Does having had a COVID-19 infection increase your risk for the development of diabetes subsequently? Some data say yes and other data say no. No matter what, it’s obviously important to screen people for diabetes routinely, pandemic or not. Remember, screening should start at age 35.

For over a decade, we have known that SARS-type viruses bind to beta cells. This could cause either direct damage to the beta cell or in some way trigger beta cell autoimmunity. We also know that COVID-19 infection increases the levels of inflammatory mediators, which could cause damage to beta cells and potentially to insulin receptors. There is a potential that having had a COVID-19 infection could increase rates of developing type 1 and/or type 2 diabetes.

However, there are other possible causes for people to develop diabetes after having a COVID-19 infection. A COVID-19 infection could cause one to seek medical care, unmasking latent type 1 and/or type 2 diabetes by causing infection-related insulin resistance and worsening preexisting mild hypoglycemia. In addition, people could have sought more medical care in the years since the pandemic has been ebbing, which may make it look like cases have increased.

For example, during the worst of the pandemic, I had multiple referrals for “COVID-19–caused new-onset diabetes” only to find that the patient had an A1c level above 10% and a history of mildly elevated blood glucose levels. This suggests to me that COVID-19 did not cause the diabetes per se but rather worsened an underlying glucose abnormality.

Since the pandemic has improved, I have also seen people diagnosed with type 2 diabetes that I think is associated with pandemic-related weight gain and inactivity.

The bigger issue is what is happening to people after COVID-19 infection who lack risk factors. What about those who we didn’t think were at high risk to get diabetes to begin with and didn’t have prediabetes?

An article by Xie and Al-Aly in The Lancet Diabetes & Endocrinology showed an increase in rates of diabetes in a large VA cohort among those who had a COVID-19 infection compared with both a contemporaneous control who did not have COVID-19 and a historical control. The researchers looked at the patient data 1 year after they’d had COVID-19, so it wasn’t the immediate post–COVID-19 phase but several months later.

They found that the risk for incident type 2 diabetes development was increased by 40% after adjusting for many risk factors. This included individuals who didn’t have traditional risk factors before they developed type 2 diabetes.

What does this mean clinically? First, pandemic or not, people need screening for diabetes and encouragement to have a healthy lifestyle. There may be an increased risk for the diagnosis of type 2 diabetes after COVID-19 infection due to a variety of different mechanisms.

As for people with type 1 diabetes, we also don’t know if having a COVID-19 infection increases their risk. We do know that there was an increase in the severity of diabetic ketoacidosis presentation during the pandemic, so we need to be sure that we reinforce sick-day rules with our patients with type 1 diabetes and that all individuals with type 1 diabetes have the ability to test their ketone levels at home.

In people with new-onset diabetes, whether type 1 or type 2, caused by COVID-19 or not, we need to treat appropriately based on their clinical situation.

Data from registries started during the pandemic will provide more definitive answers and help us find out if there is a relationship between having had COVID-19 infection and developing diabetes.

Perhaps that can help us better understand the mechanisms behind the development of diabetes overall.

Nearly half of all U.S. adults aged 45 and older have modifiable risk factors for Alzheimer’s disease and related dementias (ADRD), including hypertension, low levels of physical activity, and obesity, new research shows.

Data from the Centers for Disease Control and Prevention reveal that among nearly 162,000 adults aged 45 and older who were surveyed in 2019 as part of the Behavioral Risk Factor Surveillance System (BRFSS), nearly half had high blood pressure and did not achieve aerobic physical activity recommendations. These were the two most common modifiable risk factors for ADRD.

In addition, more than one-third (35%) of adults were obese, 19% had diabetes, 18% had depression, 15% were smokers, 11% had hearing loss, and 10% were binge drinkers.

The findings were published online in the CDC’s Morbidity and Mortality Weekly Report.
 

A missed prevention opportunity

More than 1 in 10 (11.3%) adults surveyed reported subjective cognitive decline (SCD), an early indicator of possible future ADRD. 

The prevalence of SCD increased from about 4% among adults with no modifiable risk factors for ADRD to 25% for those with four or more risk factors.

Adults with SCD were more apt to report having almost all modifiable risk factors and were more likely to report four or more risk factors (34%) than were peers without SCD (13%)

The prevalence of SCD ranged from a high of about 29% in those with depression and 25% in those with hearing loss to 11% in those who reported binge drinking.

In line with previous research, the findings indicate that American Indian or Alaska Native, Black or African American, and Hispanic populations were more likely to have modifiable risk factors for ADRD than other racial groups, the researchers reported.

The CDC’s National Healthy Brain Initiative supports culturally tailored interventions that address ADRD risk factors specifically in these populations.

In 2021, the federal government’s National Plan to Address Alzheimer’s Disease was updated to include a new goal to reduce risk factors for ADRD.

“Given the prevalence of modifiable risk factors for ADRD and anticipated growth of the older adult population and those with ADRD, this new goal has the potential to benefit a large proportion of U.S. adults,” the investigators wrote.

“In addition to helping patients discuss concerns about memory loss, health care professionals should also screen patients for modifiable risk factors, counsel patients with risk factors, and refer them to effective programs and interventions where recommended,” they advised.

A recent report from the Lancet Commission on Dementia Prevention, Intervention, and Care found that modifying 12 risk factors over the life course could delay or prevent 40% of dementia cases.

MADRID – There is increasing evidence of the impact that SARS-CoV-2 infection has on patients with diabetes. It involves the relationship between COVID-19 and new diagnoses of diabetes and blood glucose disorders, among others, in the post–COVID-19 period. These topics were addressed at the XXXIII National Congress of the Spanish Diabetes Society. They were also the central theme of the inaugural conference, Pancreatic Involvement During COVID-19: From Preclinical Studies to Clinical Relevance, which was led by Alexander Kleger, MD, PhD, head of the department of pancreatology at the Ulm (Germany) University Clinic for Internal Medicine.

The chair of the scientific committee of the congress, Franz Martín, MD, launched the conference by noting that the work of Dr. Kleger and his team has made it possible to ascertain that SARS-CoV-2 can infect pancreatic beta cells that produce insulin. This observation may help in understanding why patients with COVID-19 sometimes experience symptoms related to greater difficulty regulating blood glucose.

“In addition, the German expert and his group have described the abnormalities that occur in beta cells when they are infected by SARS-CoV-2, something especially important, given that knowledge of these abnormalities may be of great importance to understanding the possible appearance of more cases of diabetes in the future,” Dr. Martín added.

“Our data identify the human pancreas as a target of SARS-CoV-2 infection and suggest that pancreatic beta cell involvement could contribute to the metabolic dysregulation seen in COVID-19 patients,” Dr. Kleger pointed out.

In his speech, Dr. Kleger reviewed the evidence on the effects of SARS-CoV-2 that has been garnered since the start of the pandemic, and he presented his research group’s findings on the impact at the pancreatic level.

“Since March 2020, it has been seen that COVID-19 affected the pancreas, and studies published in August of that same year clearly spoke of both a worsening of diabetes and an increase in new cases of this disease diagnosed after SARS-CoV-2 infection. Also, the data showed how hospitalized patients with no previous history of diabetes experienced rapid increases in glucose levels 5 days after admission,” Dr. Kleger said.
 

Angiotensin-converting enzyme 2

As an example of the pace at which evidence on the pancreatic impact of this virus has been evolving, Dr. Kleger referred to early studies that found no angiotensin-converting enzyme 2 receptor on cells of the endocrine and exocrine pancreas. “To our surprise, in our work, we did observe the obvious presence of angiotensin-converting enzyme 2 specifically expressed in human pancreatic beta cells, something confirmed by other investigations. Another surprising aspect was verifying that the viral infection lasts longer in the pancreas than in the lungs,” said the expert.

These findings caused the researchers to realize that SARS-CoV-2 may be directly or indirectly associated with diabetes. “It is currently the subject of debate whether it may be a direct effect, infecting or directly reaching the pancreatic beta cells, or whether this involvement is a result of the effect of the infection at systemic level, in the context of the cytokine storm and the proinflammatory environment derived from it. Our current challenge is to confirm whether this virus can really replicate in pancreatic beta cells and to assess the possible existence of reinfections, among other aspects,” said Dr. Kleger.

Along with these “developing areas of knowledge,” there are several certainties regarding the link between diabetes and COVID-19. Dr. Kleger summarized the most relevant one. “Preexisting diabetes is known to be a highly prevalent comorbidity seen in 11%-22% of patients and increases the risk of severe disease and mortality.

“SARS-CoV-2 infection has also been shown to affect the exocrine pancreas, manifesting as pancreatitis in 5% of critically ill patients with COVID-19, as well as enlargement of the pancreas and abnormal levels of amylase or lipase in 7.5%-17% of patients.

“Furthermore, it is obvious that SARS-CoV-2 infection produces glycometabolic dysfunction in these patients, with increased hyperglycemia in people with type 2 diabetes and ketoacidosis in 2%-6.4% of patients with and without diabetes.”
 

After recovery

The most recent research reveals the persistence of this dysregulation long after recovery from COVID-19. “We’ve seen that in a significant proportion of patients, hyperglycemia is maintained for some time; in the specific case of hospitalized patients [without the need for assisted ventilation or other intensive care requirements], for up to more than 2 months after overcoming the illness.

“In the same way, there are studies that have shown that insulin resistance and hyperstimulation of pancreatic beta cells remain at pathological levels in the post–COVID-19 phase. And in line with increased insulin resistance, signs of hyperinflammation have also been detected in these patients.”

Dr. Kleger noted that another research area is the increased incidence of newly diagnosed diabetes after recovery from SARS-CoV-2 infection, “something that seems to be correlated with how severely the disease has been experienced and also depending on whether hospitalization or intensive care was needed. Likewise, retrospective studies have shown that the risk of developing type 2 diabetes is higher in COVID-19 patients, compared with those with other respiratory infections. Regarding the incidence of type 1 diabetes, there is evidence, particularly in the case of children, of a clear correlation between the pandemic waves and the increase in cases.

“Therefore, and in view of this data, we could say that, with regard to the involvement of SARS-CoV-2 in pancreatic beta cells, something is up, but we are not yet able to fully understand what it is. What can be confirmed based on the numerous studies carried out in this regard is that COVID-19 produces a metabolic dysregulation [hyperglycemia, insulin resistance, diabetic ketoacidosis] which in turn favors the development of diabetes in patients with no history of this disease,” said Dr. Kleger.

“Likewise, everything points to the existence of a definitively feasible infection in pancreatic beta cells associated with SARS-CoV-2, but there are still unknown aspects of the physiology that explain this effect that remain the subject of debate and deserve future studies,” he concluded.
 

Consequences of the pandemic

The experts agreed that, although COVID-19 is no longer at the center of specialist care, it is still a subject of investigation. On the conference’s opening day, an update was made on the approach to diabetes.

Care activity is gradually recovering as the time that professionals devote to COVID-19 care is reduced, “but it will take time to catch up with the care activities not carried out during the pandemic, and, unfortunately, in the coming years, we will see the repercussion of the lack or reduction of care during these years,” stressed the SED chair, Antonio Pérez Pérez, MD, director of endocrinology and nutrition of Hospital de la Santa Creu i Sant Pau, Barcelona.

Dr. Pérez stressed that the pandemic has revealed health system deficiencies in diabetes care. He added that the impact of COVID-19 on diabetes (resulting from the effects of the infection itself or from the inadequacy of prevention, diagnosis, and treatment measures) fostered a deterioration of metabolic control and a delay in the diagnosis of the disease and its complications.

“All this contributes to the fact that we currently continue to see patients with complications, especially in the case of type 2 diabetes, with more serious decompensations and diagnoses in more advanced stages of the disease. This impact has been more significant in older people from disadvantaged areas and with less capacity for self-monitoring and self-adjustment of treatment,” he added.

Describing lessons learned through the experiences accumulated in diabetes care during the pandemic, Dr. Pérez highlighted the push for virtual consultations, accessibility to drugs prescribed in electronic prescriptions, and the use of educational resources online and of telemedicine tools. “The need to invest in the health sector has also been assumed, endowing it with robustness in well-trained health personnel, to promote health education, boost efficient health organization, and invest in innovation aimed at facilitating care.”

Dr. Kleger and Dr. Pérez disclosed no relevant financial relationships.

This impact has been more significant in older people from disadvantaged areas and with less capacity for self-monitoring and self-adjustment of treatment,” he added.

Describing lessons learned through the experiences accumulated in diabetes care during the pandemic, Dr. Pérez highlighted the push for virtual consultations, accessibility to drugs prescribed in electronic prescriptions, and the use of educational resources online and of telemedicine tools. “The need to invest in the health sector has also been assumed, endowing it with robustness in well-trained health personnel, to promote health education, boost efficient health organization, and invest in innovation aimed at facilitating care.”

MADRID – There is increasing evidence of the impact that SARS-CoV-2 infection has on patients with diabetes. It involves the relationship between COVID-19 and new diagnoses of diabetes and blood glucose disorders, among others, in the post–COVID-19 period. These topics were addressed at the XXXIII National Congress of the Spanish Diabetes Society. They were also the central theme of the inaugural conference, Pancreatic Involvement During COVID-19: From Preclinical Studies to Clinical Relevance, which was led by Alexander Kleger, MD, PhD, head of the department of pancreatology at the Ulm (Germany) University Clinic for Internal Medicine.

The chair of the scientific committee of the congress, Franz Martín, MD, launched the conference by noting that the work of Dr. Kleger and his team has made it possible to ascertain that SARS-CoV-2 can infect pancreatic beta cells that produce insulin. This observation may help in understanding why patients with COVID-19 sometimes experience symptoms related to greater difficulty regulating blood glucose.

“In addition, the German expert and his group have described the abnormalities that occur in beta cells when they are infected by SARS-CoV-2, something especially important, given that knowledge of these abnormalities may be of great importance to understanding the possible appearance of more cases of diabetes in the future,” Dr. Martín added.

“Our data identify the human pancreas as a target of SARS-CoV-2 infection and suggest that pancreatic beta cell involvement could contribute to the metabolic dysregulation seen in COVID-19 patients,” Dr. Kleger pointed out.

In his speech, Dr. Kleger reviewed the evidence on the effects of SARS-CoV-2 that has been garnered since the start of the pandemic, and he presented his research group’s findings on the impact at the pancreatic level.

“Since March 2020, it has been seen that COVID-19 affected the pancreas, and studies published in August of that same year clearly spoke of both a worsening of diabetes and an increase in new cases of this disease diagnosed after SARS-CoV-2 infection. Also, the data showed how hospitalized patients with no previous history of diabetes experienced rapid increases in glucose levels 5 days after admission,” Dr. Kleger said.
 

Angiotensin-converting enzyme 2

As an example of the pace at which evidence on the pancreatic impact of this virus has been evolving, Dr. Kleger referred to early studies that found no angiotensin-converting enzyme 2 receptor on cells of the endocrine and exocrine pancreas. “To our surprise, in our work, we did observe the obvious presence of angiotensin-converting enzyme 2 specifically expressed in human pancreatic beta cells, something confirmed by other investigations. Another surprising aspect was verifying that the viral infection lasts longer in the pancreas than in the lungs,” said the expert.

These findings caused the researchers to realize that SARS-CoV-2 may be directly or indirectly associated with diabetes. “It is currently the subject of debate whether it may be a direct effect, infecting or directly reaching the pancreatic beta cells, or whether this involvement is a result of the effect of the infection at systemic level, in the context of the cytokine storm and the proinflammatory environment derived from it. Our current challenge is to confirm whether this virus can really replicate in pancreatic beta cells and to assess the possible existence of reinfections, among other aspects,” said Dr. Kleger.

Along with these “developing areas of knowledge,” there are several certainties regarding the link between diabetes and COVID-19. Dr. Kleger summarized the most relevant one. “Preexisting diabetes is known to be a highly prevalent comorbidity seen in 11%-22% of patients and increases the risk of severe disease and mortality.

“SARS-CoV-2 infection has also been shown to affect the exocrine pancreas, manifesting as pancreatitis in 5% of critically ill patients with COVID-19, as well as enlargement of the pancreas and abnormal levels of amylase or lipase in 7.5%-17% of patients.

“Furthermore, it is obvious that SARS-CoV-2 infection produces glycometabolic dysfunction in these patients, with increased hyperglycemia in people with type 2 diabetes and ketoacidosis in 2%-6.4% of patients with and without diabetes.”
 

After recovery

The most recent research reveals the persistence of this dysregulation long after recovery from COVID-19. “We’ve seen that in a significant proportion of patients, hyperglycemia is maintained for some time; in the specific case of hospitalized patients [without the need for assisted ventilation or other intensive care requirements], for up to more than 2 months after overcoming the illness.

“In the same way, there are studies that have shown that insulin resistance and hyperstimulation of pancreatic beta cells remain at pathological levels in the post–COVID-19 phase. And in line with increased insulin resistance, signs of hyperinflammation have also been detected in these patients.”

Dr. Kleger noted that another research area is the increased incidence of newly diagnosed diabetes after recovery from SARS-CoV-2 infection, “something that seems to be correlated with how severely the disease has been experienced and also depending on whether hospitalization or intensive care was needed. Likewise, retrospective studies have shown that the risk of developing type 2 diabetes is higher in COVID-19 patients, compared with those with other respiratory infections. Regarding the incidence of type 1 diabetes, there is evidence, particularly in the case of children, of a clear correlation between the pandemic waves and the increase in cases.

“Therefore, and in view of this data, we could say that, with regard to the involvement of SARS-CoV-2 in pancreatic beta cells, something is up, but we are not yet able to fully understand what it is. What can be confirmed based on the numerous studies carried out in this regard is that COVID-19 produces a metabolic dysregulation [hyperglycemia, insulin resistance, diabetic ketoacidosis] which in turn favors the development of diabetes in patients with no history of this disease,” said Dr. Kleger.

“Likewise, everything points to the existence of a definitively feasible infection in pancreatic beta cells associated with SARS-CoV-2, but there are still unknown aspects of the physiology that explain this effect that remain the subject of debate and deserve future studies,” he concluded.
 

Consequences of the pandemic

The experts agreed that, although COVID-19 is no longer at the center of specialist care, it is still a subject of investigation. On the conference’s opening day, an update was made on the approach to diabetes.

Care activity is gradually recovering as the time that professionals devote to COVID-19 care is reduced, “but it will take time to catch up with the care activities not carried out during the pandemic, and, unfortunately, in the coming years, we will see the repercussion of the lack or reduction of care during these years,” stressed the SED chair, Antonio Pérez Pérez, MD, director of endocrinology and nutrition of Hospital de la Santa Creu i Sant Pau, Barcelona.

Dr. Pérez stressed that the pandemic has revealed health system deficiencies in diabetes care. He added that the impact of COVID-19 on diabetes (resulting from the effects of the infection itself or from the inadequacy of prevention, diagnosis, and treatment measures) fostered a deterioration of metabolic control and a delay in the diagnosis of the disease and its complications.

“All this contributes to the fact that we currently continue to see patients with complications, especially in the case of type 2 diabetes, with more serious decompensations and diagnoses in more advanced stages of the disease. This impact has been more significant in older people from disadvantaged areas and with less capacity for self-monitoring and self-adjustment of treatment,” he added.

The diverse effects of obesity on lung health and disease are increasingly being teased apart, with researchers honing in on the impact of metabolic dysfunction, circulating inflammatory factors produced by adipose tissue, lipid handling, and other factors – in addition to body mass index – that are associated with the obese state.

“The bird’s eye view is that obesity completely changes lung health. It’s something we’ve only recently begun to appreciate,” said Anne E. Dixon, MA, BM, BCh, director of the Vermont Lung Center at the University of Vermont, Burlington, who is focused on the research field of obesity and lung disease.

OSA and OHS

“With sleep apnea we tend to focus on anatomic considerations, but there may be relationships or interactions between obesity and neuromuscular function and neuroventilatory control,” Susheel P. Patil, MD, PhD, director of the sleep medicine program for University Hospitals and assistant professor at Case Western Reserve University, Cleveland, said in an interview.

Some studies suggest, for instance, that TNF-alpha can increase obstructive sleep apnea (OSA) susceptibility and severity through its neuroventilatory modulating properties during sleep. And the potential for additional proinflammatory cytokines produced by adipose tissue to similarly affect upper airway neuroventilatory control is an “intriguing line” of inquiry for researchers in the sleep apnea space, he said.

Leptin is of interest particularly in obesity hypoventilation syndrome (OHS), which is characterized by chronic daytime hypercapnia. Best known as a satiety hormone, leptin is produced by adipose tissue and suppresses appetite at the central nervous system level. But it has long been known that leptin also affects ventilation and the control of breathing.

When transported across the blood-brain barrier, leptin increases the hypercapnic ventilatory response, Babak Mokhlesi, MD, MSc, codirector of the Rush Lung Center and chief of pulmonary, critical care, and sleep medicine at Rush University Medical Center in Chicago, said in an interview.

Research suggests that patients with OHS may have resistance to leptin at the central nervous system level – with leptin not reaching the sites of ventilatory control. This is a “prevailing theory” and could explain why these patients “do not augment their ventilation to maintain homeostasis, normal levels of CO₂,” Dr. Mokhlesi said.

“Why some patients with severe obesity develop CO₂ retention while others do not is not fully understood,” he said, noting that patients with OHS can normalize their CO₂ quickly when instructed to take deep breaths. “What we know is that the centers in the brain responsible for augmenting ventilation when CO₂ goes up are somehow blunted.”

In a study of obese mice led by Vsevolod Y. Polotsky, MD, PhD, of Johns Hopkins University, Baltimore – and highlighted by Dr. Mokhlesi as an example of important, recent research – leptin delivered intranasally alleviated hypoventilation (and upper-airway obstruction), while intraperitoneally administered leptin did not, seemingly overcoming “central leptin deficiency.” (Am J Respir Crit Care Med. 2019;199[6]:773-83).

“This proved that there is some level of resistance in this animal model ... and has potential for therapeutics in the future,” Dr. Mokhlesi said.

Understanding the role of insulin resistance in OSA is another research focus. Some data suggest that insulin resistance, which is more common in obesity, is more prevalent in populations with OSA, Dr. Patil said. Researchers have discussed a bidirectional relationship for years, but it’s likely that insulin resistance is a precursor, he said.

In a mechanistic study published in 2016, Dr. Patil and his coinvestigators found that obese individuals with insulin resistance but without frank diabetes or sleep apnea demonstrated preclinical elevations in pharyngeal collapsibility during sleep. The findings suggest that insulin resistance could play a causal role in OSA pathogenesis by “generating requisite elevations in pharyngeal collapsibility,” they wrote (Eur. Respir J. 2016;47[6]:1718-26).

More recently, Dr. Patil noted in the interview, there is increasing appreciation in academia that the type of fat may be important to predicting OSA. “Visceral fat has a completely different cytokine-secretion profile than subcutaneous fat ... it is the more metabolically active fat that may secondarily impact upper airway function though a neuroinflammatory mechanism,” he said. “That is one of the working hypotheses today.”
 

Asthma

Research has so roundly suggested that metabolic dysfunction contributes to severe, poorly controlled asthma that there’s recent and growing interest in targeting metabolic dysfunction as part of the treatment of obese asthma, said Dr. Dixon, whose own research in obesity and lung disease has focused on asthma.

Data from animal models and some epidemiologic studies have suggested that drugs used to treat type 2 diabetes mellitus, such as glucagon-like peptide receptor-1 (GLPR-1) agonists and metformin, may help control asthma. In one recent study – cited by Dr. Dixon in a 2022 review of obesity and asthma – people with obesity and asthma who were prescribed GLPR-1 agonists for diabetes had fewer asthma exacerbations compared with those who took other medications for diabetes (Semin Respir Crit Care Med. 2022 Feb 17. doi: 10.1055/s-0042-1742384).

There is also research interest in targeting the pro-inflammatory adipokine interleukin 6 (IL-6), since increased circulating levels of IL-6 correlate with asthma severity, and in addressing oxidative stress in asthma through treatment with a mitochondrially targeted antioxidant, she said. Oxidative stress is increased in the airways of people with obesity, and researchers believe it may contribute to the pathophysiology of obese asthma through effects on airway nitric oxide levels.

(Her own research work at the University of Vermont has found associations between poor asthma control and high levels of leptin, and similar associations involving low levels of adiponectin, an anti-inflammatory adipokine that has been shown to downregulate eosinophil recruitment in the airways.)

Weight loss has been shown in mostly small, single-center studies to improve asthma control, but short of weight loss, researchers are also investigating the role of poor dietary quality. Thus far, data suggest that it’s the composition of the diet, and not just its contribution to weight gain, that could be impactful, Dr. Dixon said.

More basic research questions cited by Dr. Dixon include the extent to which adipose tissue inflammation causes inflammation in the lungs. “It’s a little unclear whether all the metabolic dysfunction associated with poor asthma control is causing inflammation in the lungs,” she said, though “we’ve done some work here that shows mediators produced by the adipose tissue could be impacting production of inflammatory mediators by the airway epithelium.”

Overall, she said, “the big questions [in asthma] are, how does adipose tissue affect the airway? Is it through direct effects? Through effects on the immune system? And obesity is affected by diet and the gut microbiome – how can these be [impacting] the airway?”

Obesity “is associated with so many changes – the gut, the immune system, and metabolic dysfunction, in addition to airway mechanics,” she said, “that I no longer think, as I did when I came to this, that it’s just one thing. It’s probably all of these things together.”

In the meantime, questions about potential shared pathways for the development of obesity and asthma remain. “Obesity is a risk factor for developing asthma, but it’s also entirely possible that asthma is a risk factor for developing obesity,” she said. (Some data from pediatric populations, she noted, suggest that nonobese children with asthma are at increased risk of developing obesity.)

Also important, Dr. Dixon said, is “emerging literature in the last 5-10 years” that suggests that people with obesity are more susceptible to the effects of air pollution. Research involving inner-city schoolchildren with asthma, for instance, has shown that those with obesity had worse symptoms with air pollution exposure than did those who were not obese.
 

Pulmonary arterial hypertension

Some research has looked at adipose tissue–produced substances in PAH, but the most well-established association in obesity and PAH involves insulin resistance.

“I don’t think we’re certain as a community that obesity [in general] is the problem – it’s not itself considered a risk factor for PAH,” Anna R. Hemnes, MD, associate professor of medicine at Vanderbilt University Medical Center in Nashville, Tenn., said in an interview. She noted that it’s “hard to dissect obesity” apart.

Researchers are “more confident,” she said, “that insulin resistance – one feature of obesity [in some people] – is associated with worse outcomes in PAH.” Metabolic disease resembling insulin resistance is common in PAH and is believed to contribute to pulmonary vascular disease and right ventricular (RV) failure – the main cause of mortality in PAH – at least in part because of increased oxidative stress.

Dr. Hemnes led a mechanistic phase II clinical trial of metformin in PAH in which the drug was associated with improved RV fractional area change and reduced RV lipid deposition (J Am Heart Assoc. 2020;9[22]:e018349), and she’s now leading a National Institutes of Health–funded multicenter trial looking at the impact of metformin and an exercise intervention on 6-minute walk distance and World Health Organization functional class in PAH.

At the Rush Lung Center, in the meantime, Dr. Mokhlesi is utilizing animal models of OSA and OHS to explore the effect of hypoxia and nighttime hypercapnia on the development of PAH. “I think the jury is still out as to whether obesity itself is a major risk factor, but if so, by what mechanism?” he said. “Is it worsening [sleep-disordered breathing], which then worsens PAH?”
 

COPD

The focus in COPD has traditionally been on underweight, but the relationship between obesity and COPD has increasingly been recognized in the last 10-15 years, said Frits M. E. Franssen, MD, PhD, of CIRO, a research institute in Horn, the Netherlands, that treats COPD and other chronic lung diseases, and of the department of respiratory medicine at Maastricht University.

Researchers like Dr. Franssen are trying, for one, to understand obesity’s impact on COPD pathophysiology and to tease apart the impact of both conditions on disease severity and patient-related outcomes such as exercise capacity and exercise-related symptoms.

When Dr. Franssen’s group compared responses to weight-bearing exercise (6-min. walk test) and weight-supported exercise (cycling) in obese and normal weight COPD patients matched for age, gender, and degree of airflow limitation, the researchers found that walking capacity was significantly reduced while cycling capacity was preserved in the obese group (Respirology. 2016;21[3]:483-8).

Exercise-related symptoms (dyspnea and leg fatigue) were largely comparable between the obese and normal-weight COPD patients in both exercise modalities. However, in other studies, dyspnea ratings during cycling – at any given level of ventilation – have been lower in obese patients, indicating that “additional fat mass may have a beneficial effect on lung functioning [in non–weight-bearing exercise],” he said in an interview.

Dr. Franssen’s group also has assessed body composition in overweight and obese patients with COPD and found that a significant number have low muscle mass. These patients had worse lung function, exercise tolerance, and muscle strength compared to patients with comparable BMI and normal muscle mass (Respir Res. 2021 Mar 25. doi: 10.1186/s12931-021-01689-w).

“We’d always thought that obese patients have normal muscle mass ... but now we know it can be dramatically low,” he said. In assessing obesity and formulating any weight loss plans, “we’re now interested not only in weight but in the distribution of fat mass and fat-free mass ... and in maintaining muscle mass in patients who are [prescribed dietary interventions].”

Paradoxically, in patients with severe COPD, obesity is associated with prolonged survival, while in patients with mild to moderate COPD, obesity is associated with increased mortality risk, he noted.

The impact of adipose tissue and the chronic inflammation and metabolic disturbances that characterize obesity are currently largely unexplored, he said. Researchers have not yet studied what optimal weights may be for patients with COPD. “And we’re interested in the questions, are body weight and body composition the result of the disease, or [are they] determining the type of COPD one will get?” Dr. Franssen said.

Patients with COPD who are obese have “more of the phenotype of chronic bronchitis,” he noted, “while typical emphysema patients are normally underweight.”

The diverse effects of obesity on lung health and disease are increasingly being teased apart, with researchers honing in on the impact of metabolic dysfunction, circulating inflammatory factors produced by adipose tissue, lipid handling, and other factors – in addition to body mass index – that are associated with the obese state.

“Why some patients with severe obesity develop CO₂ retention while others do not is not fully understood,” he said, noting that patients with OHS can normalize their CO₂ quickly when instructed to take deep breaths. “What we know is that the centers in the brain responsible for augmenting ventilation when CO₂ goes up are somehow blunted.”

In a study of obese mice led by Vsevolod Y. Polotsky, MD, PhD, of Johns Hopkins University, Baltimore – and highlighted by Dr. Mokhlesi as an example of important, recent research – leptin delivered intranasally alleviated hypoventilation (and upper-airway obstruction), while intraperitoneally administered leptin did not, seemingly overcoming “central leptin deficiency.” (Am J Respir Crit Care Med. 2019;199[6]:773-83).

“This proved that there is some level of resistance in this animal model ... and has potential for therapeutics in the future,” Dr. Mokhlesi said.

Understanding the role of insulin resistance in OSA is another research focus. Some data suggest that insulin resistance, which is more common in obesity, is more prevalent in populations with OSA, Dr. Patil said. Researchers have discussed a bidirectional relationship for years, but it’s likely that insulin resistance is a precursor, he said.

In a mechanistic study published in 2016, Dr. Patil and his coinvestigators found that obese individuals with insulin resistance but without frank diabetes or sleep apnea demonstrated preclinical elevations in pharyngeal collapsibility during sleep. The findings suggest that insulin resistance could play a causal role in OSA pathogenesis by “generating requisite elevations in pharyngeal collapsibility,” they wrote (Eur. Respir J. 2016;47[6]:1718-26).

More recently, Dr. Patil noted in the interview, there is increasing appreciation in academia that the type of fat may be important to predicting OSA. “Visceral fat has a completely different cytokine-secretion profile than subcutaneous fat ... it is the more metabolically active fat that may secondarily impact upper airway function though a neuroinflammatory mechanism,” he said. “That is one of the working hypotheses today.”
 

Asthma

Research has so roundly suggested that metabolic dysfunction contributes to severe, poorly controlled asthma that there’s recent and growing interest in targeting metabolic dysfunction as part of the treatment of obese asthma, said Dr. Dixon, whose own research in obesity and lung disease has focused on asthma.

Data from animal models and some epidemiologic studies have suggested that drugs used to treat type 2 diabetes mellitus, such as glucagon-like peptide receptor-1 (GLPR-1) agonists and metformin, may help control asthma. In one recent study – cited by Dr. Dixon in a 2022 review of obesity and asthma – people with obesity and asthma who were prescribed GLPR-1 agonists for diabetes had fewer asthma exacerbations compared with those who took other medications for diabetes (Semin Respir Crit Care Med. 2022 Feb 17. doi: 10.1055/s-0042-1742384).

There is also research interest in targeting the pro-inflammatory adipokine interleukin 6 (IL-6), since increased circulating levels of IL-6 correlate with asthma severity, and in addressing oxidative stress in asthma through treatment with a mitochondrially targeted antioxidant, she said. Oxidative stress is increased in the airways of people with obesity, and researchers believe it may contribute to the pathophysiology of obese asthma through effects on airway nitric oxide levels.

(Her own research work at the University of Vermont has found associations between poor asthma control and high levels of leptin, and similar associations involving low levels of adiponectin, an anti-inflammatory adipokine that has been shown to downregulate eosinophil recruitment in the airways.)

Weight loss has been shown in mostly small, single-center studies to improve asthma control, but short of weight loss, researchers are also investigating the role of poor dietary quality. Thus far, data suggest that it’s the composition of the diet, and not just its contribution to weight gain, that could be impactful, Dr. Dixon said.

More basic research questions cited by Dr. Dixon include the extent to which adipose tissue inflammation causes inflammation in the lungs. “It’s a little unclear whether all the metabolic dysfunction associated with poor asthma control is causing inflammation in the lungs,” she said, though “we’ve done some work here that shows mediators produced by the adipose tissue could be impacting production of inflammatory mediators by the airway epithelium.”

Overall, she said, “the big questions [in asthma] are, how does adipose tissue affect the airway? Is it through direct effects? Through effects on the immune system? And obesity is affected by diet and the gut microbiome – how can these be [impacting] the airway?”

Obesity “is associated with so many changes – the gut, the immune system, and metabolic dysfunction, in addition to airway mechanics,” she said, “that I no longer think, as I did when I came to this, that it’s just one thing. It’s probably all of these things together.”

In the meantime, questions about potential shared pathways for the development of obesity and asthma remain. “Obesity is a risk factor for developing asthma, but it’s also entirely possible that asthma is a risk factor for developing obesity,” she said. (Some data from pediatric populations, she noted, suggest that nonobese children with asthma are at increased risk of developing obesity.)

Also important, Dr. Dixon said, is “emerging literature in the last 5-10 years” that suggests that people with obesity are more susceptible to the effects of air pollution. Research involving inner-city schoolchildren with asthma, for instance, has shown that those with obesity had worse symptoms with air pollution exposure than did those who were not obese.
 

Pulmonary arterial hypertension

Some research has looked at adipose tissue–produced substances in PAH, but the most well-established association in obesity and PAH involves insulin resistance.

“I don’t think we’re certain as a community that obesity [in general] is the problem – it’s not itself considered a risk factor for PAH,” Anna R. Hemnes, MD, associate professor of medicine at Vanderbilt University Medical Center in Nashville, Tenn., said in an interview. She noted that it’s “hard to dissect obesity” apart.

Researchers are “more confident,” she said, “that insulin resistance – one feature of obesity [in some people] – is associated with worse outcomes in PAH.” Metabolic disease resembling insulin resistance is common in PAH and is believed to contribute to pulmonary vascular disease and right ventricular (RV) failure – the main cause of mortality in PAH – at least in part because of increased oxidative stress.

Dr. Hemnes led a mechanistic phase II clinical trial of metformin in PAH in which the drug was associated with improved RV fractional area change and reduced RV lipid deposition (J Am Heart Assoc. 2020;9[22]:e018349), and she’s now leading a National Institutes of Health–funded multicenter trial looking at the impact of metformin and an exercise intervention on 6-minute walk distance and World Health Organization functional class in PAH.

At the Rush Lung Center, in the meantime, Dr. Mokhlesi is utilizing animal models of OSA and OHS to explore the effect of hypoxia and nighttime hypercapnia on the development of PAH. “I think the jury is still out as to whether obesity itself is a major risk factor, but if so, by what mechanism?” he said. “Is it worsening [sleep-disordered breathing], which then worsens PAH?”
 

COPD

The focus in COPD has traditionally been on underweight, but the relationship between obesity and COPD has increasingly been recognized in the last 10-15 years, said Frits M. E. Franssen, MD, PhD, of CIRO, a research institute in Horn, the Netherlands, that treats COPD and other chronic lung diseases, and of the department of respiratory medicine at Maastricht University.

Researchers like Dr. Franssen are trying, for one, to understand obesity’s impact on COPD pathophysiology and to tease apart the impact of both conditions on disease severity and patient-related outcomes such as exercise capacity and exercise-related symptoms.

When Dr. Franssen’s group compared responses to weight-bearing exercise (6-min. walk test) and weight-supported exercise (cycling) in obese and normal weight COPD patients matched for age, gender, and degree of airflow limitation, the researchers found that walking capacity was significantly reduced while cycling capacity was preserved in the obese group (Respirology. 2016;21[3]:483-8).

Exercise-related symptoms (dyspnea and leg fatigue) were largely comparable between the obese and normal-weight COPD patients in both exercise modalities. However, in other studies, dyspnea ratings during cycling – at any given level of ventilation – have been lower in obese patients, indicating that “additional fat mass may have a beneficial effect on lung functioning [in non–weight-bearing exercise],” he said in an interview.

Dr. Franssen’s group also has assessed body composition in overweight and obese patients with COPD and found that a significant number have low muscle mass. These patients had worse lung function, exercise tolerance, and muscle strength compared to patients with comparable BMI and normal muscle mass (Respir Res. 2021 Mar 25. doi: 10.1186/s12931-021-01689-w).

“We’d always thought that obese patients have normal muscle mass ... but now we know it can be dramatically low,” he said. In assessing obesity and formulating any weight loss plans, “we’re now interested not only in weight but in the distribution of fat mass and fat-free mass ... and in maintaining muscle mass in patients who are [prescribed dietary interventions].”

Paradoxically, in patients with severe COPD, obesity is associated with prolonged survival, while in patients with mild to moderate COPD, obesity is associated with increased mortality risk, he noted.

The impact of adipose tissue and the chronic inflammation and metabolic disturbances that characterize obesity are currently largely unexplored, he said. Researchers have not yet studied what optimal weights may be for patients with COPD. “And we’re interested in the questions, are body weight and body composition the result of the disease, or [are they] determining the type of COPD one will get?” Dr. Franssen said.

Patients with COPD who are obese have “more of the phenotype of chronic bronchitis,” he noted, “while typical emphysema patients are normally underweight.”

An intensive 1-year behavior therapy program aimed at changing a person’s response to food “cues” might help people with obesity lose a modest amount of weight, a randomized clinical trial suggests.

“Patients who are food-cue sensitive often feel out of control with their eating; they cannot resist food and/or cannot stop thinking about food,” said lead author Kerri N. Boutelle, PhD.

“Behavioral weight loss skills are not sufficient for these individuals,” so they designed this new approach, Dr. Boutelle, of the University of California, San Diego, explained in a press release.

The regulation of cues (ROC) intervention trains individuals to respond to their hunger and to resist eating highly craved foods (internal management), in contrast to behavioral weight loss programs that focus on counting calories (external management), Dr. Boutelle explained in an email.

The results of the Providing Adult Collaborative Interventions for Ideal Changes (PACIFIC) clinical trial, including follow-up out to 2 years, were published  in JAMA Network Open.

Patients in the behavioral weight loss therapy group or the combined ROC and behavioral weight loss therapy group lost more weight at 6 months than patients in the ROC group – but then they slowly regained weight (whereas patients in the ROC group did not).

At 24 months, the three groups had a similar modest weight loss, compared with a control group that did not lose weight.

“We believe these internal management strategies are more durable over time,” said Dr. Boutelle.  

However, two obesity experts, who helped develop the Canadian Adult Obesity Clinical Practice Guidelines, cautioned in emails that the intervention is very labor-intensive with less than 5% weight loss.

Four interventions

The trial was conducted at the Center for Healthy Eating and Activity Research at the University of California, San Diego, from December 2015 to December 2019.

Researchers randomized 271 adults with a mean BMI of 35 kg/m² to one of four interventions:

• Regulation of cues: Patients were not given a prescribed diet but instead were given skills to tolerate cravings and respond better to hunger or satiety cues.
• Behavioral weight loss therapy: Patients were advised to follow a balanced, calorie-deficit diet based on their weight and given related skills.
• Combined regulation of cues plus behavioral weight loss therapy.
• Control: Patients received information about nutrition and stress management plus mindfulness training and were encouraged to find social support.

Therapy was given as 26 group sessions, 90 minutes each, over 12 months, with 16 weekly sessions, four biweekly sessions, and six monthly booster sessions.

Participants were asked to take part in 150 minutes of moderate to high intensity exercise each week and aim for 10,000 steps per day. All patients except those in the control group received a pedometer.

The patients were a mean age of 46 years, 82% were women and 62% were White.

At the end of the 12-month intervention, mean BMI had dropped by –1.18 kg/m² in the ROC group and by –1.58 kg/m² and –1.56 kg/m² in the other two groups, compared with the control group, where BMI was virtually unchanged.

At 24 months follow-up, mean BMI was similar (roughly 33.5 kg/m²) in the ROC, the behavioral weight loss therapy, and the ROC plus behavioral weight loss therapy groups.

There was weight regain from 12 months in the latter two groups but not in the ROC group.
 

‘Nice study, but not practical’

“This is a nice study, but in no way is it practical,” Sean Wharton, MD, summarized.

“I think it may have difficulty finding its way into everyday practice,” said Dr. Wharton, adjunct professor at McMaster University, Hamilton, Ontario.

Also, “it does not compare ROC to pharmacotherapy,” he added, which is “quickly becoming the gold standard for obesity management. We have learned that adding intensive behavioral therapy – more visits and possibly a liquid diet as part of the weight management and some light group counseling – to pharmacotherapy does not add much.”

However, Dr. Wharton conceded that if an individual did not want, or could not take, pharmacotherapy and had access to ROC sessions, this might be a good option.

“The challenge will be offering this labor-intensive tool to 40% of Americans living with obesity,” he said.

The ROC intervention “is very different than a GP’s office that may see a patient two to three times/year max, with limited supports,” Dr. Wharton pointed out.

“It is labor-intensive, not reproducible in most places, and cannot be sustained forever. There is no evidence that the learning remains past the treatment interval. For example, 2 to 3 years later, are patients still adhering to ROC? Is weight still decreased or do they need to come to classes every month forever?”  
 

‘Modest weight loss, doubtful long-term benefits’

Similarly, Arya M. Sharma, MD, said: “While this [ROC] approach may be helpful for some individuals, given the rather modest weight loss achieved (despite considerable efforts and a cash incentive), the long-term clinical benefits remain doubtful.”

The weight loss of less than 5% over 24 months is “in the ballpark of other behavioral weight-loss interventions,” said Dr. Sharma, of the University of Edmonton, Alberta, and past scientific director of Obesity Canada.  

“I’m not convinced” about less weight regain, he added. “The difference between the groups is minimal. While this approach may well help individuals better deal with food cues, it does not change the underlying biology of weight regain.”

“This approach at best may help prevent future weight gain in susceptible individuals,” he speculated. “I would consider this more as a weight-stabilization than a weight-loss strategy.”
 

Next steps

Insurance doesn’t always cover weight loss with a mental health professional, Dr. Boutelle agreed. “However, there are eating disorder categories that also apply to many of our food-cue-sensitive patients, including binge eating,” she noted.

“We believe that ROC is an alternative model for weight loss that could be offered to patients who are interested or for whom behavioral weight loss has not been successful ... who are highly food-cue-responsive.”

The group is writing a manual about the ROC program to disseminate to other behavior therapists. They are also studying ROC in another clinical trial, Solutions for Hunger and Regulating Eating (SHARE). The ROC program is being offered at the UC San Diego Center for Healthy Eating and Activity Research, of which Dr. Boutelle is director.

The study was supported by grants from the National Institutes of Health. The researchers have reported no relevant financial relationships. Dr. Wharton has reported receiving honoraria and travel expenses and has participated in academic advisory boards for Novo Nordisk, Bausch Health, Eli Lilly, and Janssen. He is the medical director of a medical clinic specializing in weight management and diabetes. Dr. Sharma has reported receiving speakers bureau and consulting fees from Novo Nordisk, Bausch Pharmaceuticals, and AstraZeneca.

Many strategies widely considered “standard care” for managing spontaneous intracerebral hemorrhage (ICH) are not as effective as previously thought and are no longer recommended in updated guidelines from the American Heart Association/American Stroke Association (ASA).

Compression stockings, antiseizure medication, and steroid treatment are among the treatments with uncertain effectiveness, the writing group says.

The 2022 Guideline for the Management of Patients With Spontaneous ICH was published online  in Stroke. The 80-page document contains major changes and refinements to the 2015 guideline on ICH management.

“Advances have been made in an array of fields related to ICH, including the organization of regional health care systems, reversal of the negative effects of blood thinners, minimally invasive surgical procedures, and the underlying disease in small blood vessels,” Steven M. Greenberg, MD, PhD, chair of the guideline writing group with Harvard Medical School and Massachusetts General Hospital, both in Boston, said in a news release.

“We’ve updated sections across the board. There’s probably no area that went untouched with some tweaking and new evidence added that led to some changes in level of evidence or strength of a recommendation,” Dr. Greenberg added in an interview with this news organization.

“Each section comes with knowledge gaps, and it wasn’t hard to come up with knowledge gaps in every section,” Dr. Greenberg acknowledged.

Time-honored treatments no more?

Among the key updates are changes to some “time-honored” treatments that continue to be used with some “regularity” for patients with ICH, yet appear to confer either no benefit or harm, Dr. Greenberg said.

For example, for emergency or critical care treatment of ICH, prophylactic corticosteroids or continuous hyperosmolar therapy is not recommended, because it appears to have no benefit for outcome, while use of platelet transfusions outside the setting of emergency surgery or severe thrombocytopenia appears to worsen outcome, the authors say.

Use of graduated knee- or thigh-high compression stockings alone is not an effective prophylactic therapy for prevention of deep vein thrombosis (DVT). Instead, intermittent pneumatic compression (IPC) starting on the day of diagnosis is now recommended for DVT prophylaxis.

“This is an area where we still have a lot of exploration to do. It is unclear whether even specialized compression devices reduce the risks of deep vein thrombosis or improve the overall health of people with a brain bleed,” Dr. Greenberg said in the release.

The new guidance advises against use of antiseizure or antidepressant medications for ICH patients in whom there is no evidence of seizures or depression.

In clinical trials, antiseizure medication did not contribute to improvements in functionality or long-term seizure control, and the use of antidepressants increased the chance of bone fractures, the authors say.

The guideline also provides updated recommendations for acute reversal of anticoagulation after ICH. It highlights the use of protein complex concentrate for reversal of vitamin K antagonists, such as warfarin; idarucizumab for reversal of the thrombin inhibitor dabigatran; and andexanet alfa for reversal of factor Xa inhibitors, such as rivaroxaban, apixaban, and edoxaban.

For acute blood pressure lowering after mild to moderate ICH, treatment regimens that limit blood pressure variability and achieve smooth, sustained blood pressure control appear to reduce hematoma expansion and yield better functional outcome, the guideline says.

It also notes that minimally invasive approaches for hematoma evacuation, compared with medical management alone‚ have been shown to reduce mortality.

For patients with cerebellar hemorrhage, indications for immediate surgical evacuation with or without an external ventricular drain to reduce mortality now include larger volume (> 15 mL) in addition to previously recommended indications of neurologic deterioration, brainstem compression, and hydrocephalus, the authors note.

However, a “major knowledge gap is whether we can improve functional outcome with hematoma evacuation,” Dr. Greenberg said.
 

Multidisciplinary care

For rehabilitation after ICH, the guideline reinforces the importance of having a multidisciplinary team to develop a comprehensive plan for recovery.

Starting rehabilitation activities such as stretching and functional task training may be considered 24 to 48 hours following mild or moderate ICH. However, early aggressive mobilization within the first 24 hours has been linked to an increased risk of death within 14 days after an ICH, the guideline says.

Knowledge gaps include how soon it’s safe to return to work, drive, and participate in other social engagements. Recommendations on sexual activity and exercise levels that are safe after a stroke are also needed.

“People need additional help with these lifestyle changes, whether it’s moving around more, curbing their alcohol use, or eating healthier foods. This all happens after they leave the hospital, and we need to be sure we are empowering families with the information they may need to be properly supportive,” Dr. Greenberg says in the release.

The guideline points to the patient’s home caregiver as a “key and sometimes overlooked” member of the care team. It recommends psychosocial education, practical support, and training for the caregiver to improve the patient’s balance, activity level, and overall quality of life.
 

Opportunity for prevention?

The guideline also suggests there may be an opportunity to prevent ICH in some people through neuroimaging markers.

While neuroimaging is not routinely performed as a part of risk stratification for primary ICH risk, damage to small blood vessels that is associated with ICH may be evident on MRI that could signal future ICH risk, the guideline says.

“We added to the guidelines for the first time a section on mostly imaging markers of risk for having a first-ever hemorrhage,” Dr. Greenberg said in an interview.

“We don’t make any recommendations as to how to act on these markers because there is a knowledge gap. The hope is that we’ll see growth in our ability to predict first-ever hemorrhage and be able to do things to prevent first-ever hemorrhage,” he said.

“We believe the wide range of knowledge set forth in the new guideline will translate into meaningful improvements in ICH care,” Dr. Greenberg adds in the release.

The updated guideline has been endorsed by the American Association of Neurological Surgeons and Congress of Neurological Surgeons, the Society of Vascular and Interventional Neurology, and the Neurocritical Care Society. The American Academy of Neurology has affirmed the value of this statement as an educational tool for neurologists.

Many strategies widely considered “standard care” for managing spontaneous intracerebral hemorrhage (ICH) are not as effective as previously thought and are no longer recommended in updated guidelines from the American Heart Association/American Stroke Association (ASA).

Compression stockings, antiseizure medication, and steroid treatment are among the treatments with uncertain effectiveness, the writing group says.

The 2022 Guideline for the Management of Patients With Spontaneous ICH was published online  in Stroke. The 80-page document contains major changes and refinements to the 2015 guideline on ICH management.

“Advances have been made in an array of fields related to ICH, including the organization of regional health care systems, reversal of the negative effects of blood thinners, minimally invasive surgical procedures, and the underlying disease in small blood vessels,” Steven M. Greenberg, MD, PhD, chair of the guideline writing group with Harvard Medical School and Massachusetts General Hospital, both in Boston, said in a news release.

“We’ve updated sections across the board. There’s probably no area that went untouched with some tweaking and new evidence added that led to some changes in level of evidence or strength of a recommendation,” Dr. Greenberg added in an interview with this news organization.

“Each section comes with knowledge gaps, and it wasn’t hard to come up with knowledge gaps in every section,” Dr. Greenberg acknowledged.

Time-honored treatments no more?

Among the key updates are changes to some “time-honored” treatments that continue to be used with some “regularity” for patients with ICH, yet appear to confer either no benefit or harm, Dr. Greenberg said.

For example, for emergency or critical care treatment of ICH, prophylactic corticosteroids or continuous hyperosmolar therapy is not recommended, because it appears to have no benefit for outcome, while use of platelet transfusions outside the setting of emergency surgery or severe thrombocytopenia appears to worsen outcome, the authors say.

Use of graduated knee- or thigh-high compression stockings alone is not an effective prophylactic therapy for prevention of deep vein thrombosis (DVT). Instead, intermittent pneumatic compression (IPC) starting on the day of diagnosis is now recommended for DVT prophylaxis.

“This is an area where we still have a lot of exploration to do. It is unclear whether even specialized compression devices reduce the risks of deep vein thrombosis or improve the overall health of people with a brain bleed,” Dr. Greenberg said in the release.

The new guidance advises against use of antiseizure or antidepressant medications for ICH patients in whom there is no evidence of seizures or depression.

In clinical trials, antiseizure medication did not contribute to improvements in functionality or long-term seizure control, and the use of antidepressants increased the chance of bone fractures, the authors say.

The guideline also provides updated recommendations for acute reversal of anticoagulation after ICH. It highlights the use of protein complex concentrate for reversal of vitamin K antagonists, such as warfarin; idarucizumab for reversal of the thrombin inhibitor dabigatran; and andexanet alfa for reversal of factor Xa inhibitors, such as rivaroxaban, apixaban, and edoxaban.

For acute blood pressure lowering after mild to moderate ICH, treatment regimens that limit blood pressure variability and achieve smooth, sustained blood pressure control appear to reduce hematoma expansion and yield better functional outcome, the guideline says.

It also notes that minimally invasive approaches for hematoma evacuation, compared with medical management alone‚ have been shown to reduce mortality.

For patients with cerebellar hemorrhage, indications for immediate surgical evacuation with or without an external ventricular drain to reduce mortality now include larger volume (> 15 mL) in addition to previously recommended indications of neurologic deterioration, brainstem compression, and hydrocephalus, the authors note.

However, a “major knowledge gap is whether we can improve functional outcome with hematoma evacuation,” Dr. Greenberg said.
 

Multidisciplinary care

For rehabilitation after ICH, the guideline reinforces the importance of having a multidisciplinary team to develop a comprehensive plan for recovery.

Starting rehabilitation activities such as stretching and functional task training may be considered 24 to 48 hours following mild or moderate ICH. However, early aggressive mobilization within the first 24 hours has been linked to an increased risk of death within 14 days after an ICH, the guideline says.

Knowledge gaps include how soon it’s safe to return to work, drive, and participate in other social engagements. Recommendations on sexual activity and exercise levels that are safe after a stroke are also needed.

“People need additional help with these lifestyle changes, whether it’s moving around more, curbing their alcohol use, or eating healthier foods. This all happens after they leave the hospital, and we need to be sure we are empowering families with the information they may need to be properly supportive,” Dr. Greenberg says in the release.

The transition from perimenopause to menopause is accompanied by a proatherogenic shift in lipids and other circulating metabolites that potentially predispose women to cardiovascular disease (CVD). Now, for the first time, a new prospective cohort study quantifies the link between hormonal shifts and these lipid changes.

However, hormone therapy (HT) somewhat mitigates the shift and may help protect menopausal women from some elevated CVD risk, the same study suggests.

“Menopause is not avoidable, but perhaps the negative metabolite shift can be diminished by lifestyle choices such as eating healthily and being physically active,” senior author Eija Laakkonen, MD, University of Jyväskylä, Finland, told this news organization in an email.

“And women should especially pay attention to the quality of dietary fats and amount of exercise [they get] to maintain cardiorespiratory fitness,” she said, adding that women should discuss the option of HT with their health care providers.

Asked to comment, JoAnn Manson, MD, of Harvard Medical School, Boston, and past president of the North American Menopause Society, said there is strong evidence that women undergo negative cardiometabolic changes during the menopausal transition.

Changes include those in body composition (an increase in visceral fat and waist circumference), as well as unfavorable shifts in the lipid profile, as reflected by increases in low-density lipoprotein cholesterol (LDL-C) and triglycerides and a decrease in high-density lipoprotein cholesterol (HDL-C).

It’s also clear from a variety of cohort studies that HT blunts menopausal-related increases in body weight, percentage of body fat, as well as visceral fat, she said.

So the new findings do seem to “parallel” those of other perimenopausal to menopausal transition studies, which include HT having “favorable effects on lipids,” Dr. Manson said. HT “lowers LDL-C and increases HDL-C, and this is especially true when it is given orally,” but even transdermal delivery has shown some benefits, she observed.
 

Shift in hormones causes 10% of lipid changes after menopause

The new study, by Jari E. Karppinen, also of the University of Jyväskylä, and colleagues, was recently published in the European Journal of Preventive Cardiology. The data are from the Estrogenic Regulation of Muscle Apoptosis (ERMA) prospective cohort study.

In total, 218 women were tracked from perimenopause through to early postmenopause, 35 of whom started HT, mostly oral preparations. The women were followed for a median of 14 months. Their mean age was 51.7 years when their hormone and metabolite profiles were first measured.

Previous studies have shown that menopause is associated with levels of metabolites that promote CVD, but this study is the first to specifically link this shift with changes in female sex hormones, the researchers stress.

“Menopause was associated with a statistically significant change in 85 metabolite measures,” Mr. Karppinen and colleagues report.

Analyses showed that the menopausal hormonal shift directly explained the change in 64 of the 85 metabolites, with effect sizes ranging from 2.1% to 11.2%. 

These included increases in LDL-C, triglycerides, and fatty acids. Analyses were adjusted for age at baseline, duration of follow-up, education level, smoking status, alcohol use, physical activity, and diet quality.

More specifically, investigators found that all apoB-containing particle counts as well as particle diameters increased over follow-up, although no change occurred in HDL particles.

They also found cholesterol concentrations in all apoB-containing lipoprotein classes to increase and triglyceride concentrations to increase in very low-density lipoprotein and HDL particles.

“These findings, including HDL triglycerides, can be interpreted as signs of poor metabolic health since, despite higher HDL-C being good for health, high HDL triglyceride levels are associated with a higher risk of coronary heart disease,” Dr. Laakkonen emphasized.

Among the 35 women who initiated HT on study enrollment, investigators did note, on exploratory analysis, increases in HDL-C and reductions in LDL-C.

“The number of women starting HT was small, and the type of HT was not controlled,” Dr. Laakkonen cautioned, however.

“Nevertheless, our observations support clinical guidelines to initiate HT early into menopause, as this timing offers the greatest cardioprotective effect,” she added.

The study was supported by the Academy of Finland. The authors and Dr. Manson have reported no relevant financial relationships. Dr. Manson is a contributor to Medscape.

Infertile men may be twice as likely to develop invasive breast cancer as those without fertility issues, according to new research funded by the charity Breast Cancer Now and published in Breast Cancer Research. The study is one of the largest ever into male breast cancer, enabling the team to show a highly statistically significant association.  

A link with infertility had been suspected, since parity markedly reduces the risk of female breast cancer; there are known genetic links in both sexes, and a high risk of both breast cancer and infertility among men with Klinefelter syndrome, suggesting some sex hormone-related involvement. However, the rarity of breast cancer in men – with an annual incidence of about 370 cases and 80 deaths per year in the United Kingdom – meant that past studies were necessarily small and yielded mixed results.

“Compared with previous studies, our study of male breast cancer is large,” said study coauthor Michael Jones, PhD, of the division of genetics and epidemiology at the Institute of Cancer Research (ICR) in London. “It was carried out nationwide across England and Wales and was set in motion more than 15 years ago. Because of how rare male breast cancer is, it took us over 12 years to identify and interview the nearly 2,000 men with breast cancer who were part of this study.”

The latest research is part of the wider Breast Cancer Now Male Breast Cancer Study, launched by the charity in 2007. For the new study, the ICR team interviewed 1,998 males living in England and Wales who had been diagnosed with breast cancer between 2005 and 2017. All were aged under 80 but most 60 or older at diagnosis; 92% of their tumors were invasive, and almost all were estrogen receptor positive (98.5% of those with known status).

Their responses were compared with those of a control group of 1,597 men without breast cancer, matched by age at diagnosis and geographic region, recruited from male non-blood relatives of cases and from husbands of women participating in the Generations cohort study of breast cancer etiology.
 

Raised risk with history of male infertility

Overall, 112 cases (5.6%) and 80 controls (5.0%) reported that they had had infertility problems for which they or their partner had consulted a doctor or infertility clinic. This represented a raised odds ratio of 1.29 (95% confidence interval, 0.94-1.77), which was statistically not significant. However, when analyzed by outcome of the infertility consultation, there was a significant and more than doubled risk of breast cancer among men who were diagnosed as the source of the couple’s infertility (OR = 2.03 [1.18-3.49]), whereas this was not the case among men whose partner was the source (OR = 0.86 [0.51-1.45]) or for whom no source was identified (OR = 1.26 [0.71-2.24]).

In addition, proportionately fewer cases (1,615, or 80.8%) compared with controls (1,423, or 89.1%) had fathered any children, also giving a statistically significantly raised risk of breast cancer for men with no biological children (OR = 1.50 [1.21-1.86], P < .001), “congruent with infertility as a risk factor,” the authors said. The risk was statistically significant for invasive tumors but not for the much smaller number of in situ tumors.

Analysis by number of children showed a decreasing risk with increasing numbers of children, with a highly significant (P < .001) inverse trend where zero was included as a value, but a borderline significant trend (P = .04) if it was not. The team noted that number of children beyond one is difficult to interpret as an indicator of male fertility, since it may more reflect social and cultural factors than fertility per se.

Baseline demographic factors were adjusted for in the risk analyses, and results were not materially changed by sensitivity analyses adjusting additionally for alcohol consumption, smoking, liver disease, and family history of breast cancer. The association also largely remained after exclusion of patients with other preexisting potential confounders including severe obesity and testicular abnormalities, and was consistent irrespective of HER-2 status (there were too few ER-negative tumors to analyze results by ER status).
 

Potential underlying factors

“The causes of breast cancer in men are largely unknown, partly because it is rare and partly because previous studies have been small,” Dr. Jones said. “The evidence presented in our study suggests that the association of infertility and breast cancer should be confirmed with further research, and future investigations are needed into the potential underlying factors, such as hormone imbalances.”

Commenting on the study, Fiona Osgun, senior health information manager at Cancer Research UK, told this news organization: “Overall, there isn’t strong evidence that infertility is a risk factor for male breast cancer. This study helps to shed light onto a cancer type that is sadly still not very well understood, but much more research is needed to say that infertility is a risk factor for male breast cancer.”

She added that although male breast cancer is a rare condition, it’s still important for men to be aware of what looks and feels normal for them, and to be encouraged to seek medical advice if something is not quite right.

A spokesperson for Breast Cancer UK told this news organization: “[We] believe it’s important to understand what leads to breast cancer in men as well as women and that high quality, long-term studies such as this will help with this understanding.

The findings are consistent with an earlier study that found that U.S. men who have never fathered children are at higher risk of breast cancer. This new long-term U.K. study provides strong evidence, which supports this finding.  

“As the authors note, the biological reasons are unclear, but may be associated with altered hormone levels. The ratio of circulating levels of estrogen and androgens (e.g. testosterone) is crucial in healthy functioning of breast tissue. Disruption to this, for example as a result of damage to testes, may affect both fertility and breast cancer risk.

“It is also possible that external factors, such as exposure to certain endocrine (hormone) disrupting chemicals (EDCs), which affect sex hormones, may also affect both fertility and breast cancer risk.

“More studies into breast cancer in men are needed to help us understand better all the risk factors associated with this disease including both hormonal factors and chemical exposures.”

Simon Vincent, PhD, director of research, support, and influencing at Breast Cancer Now, said: “Research has discovered different treatments directed at some features of breast cancer in women; however, breast cancer is not as well understood for men. This is why Breast Cancer Now funds the Male Breast Cancer Study, which looks at what might cause the disease in men. Discovering a link between infertility and male breast cancer is a step towards us understanding male breast cancer and how we could find more ways to diagnose and treat men – and possibly women – with this devastating disease.”

However, the rarity of breast cancer in men – with an annual incidence of about 370 cases and 80 deaths per year in the United Kingdom – meant that past studies were necessarily small and yielded mixed results.

“Compared with previous studies, our study of male breast cancer is large,” said study coauthor Michael Jones, PhD, of the division of genetics and epidemiology at the Institute of Cancer Research (ICR) in London. “It was carried out nationwide across England and Wales and was set in motion more than 15 years ago. Because of how rare male breast cancer is, it took us over 12 years to identify and interview the nearly 2,000 men with breast cancer who were part of this study.”

The latest research is part of the wider Breast Cancer Now Male Breast Cancer Study, launched by the charity in 2007. For the new study, the ICR team interviewed 1,998 males living in England and Wales who had been diagnosed with breast cancer between 2005 and 2017. All were aged under 80 but most 60 or older at diagnosis; 92% of their tumors were invasive, and almost all were estrogen receptor positive (98.5% of those with known status).

Their responses were compared with those of a control group of 1,597 men without breast cancer, matched by age at diagnosis and geographic region, recruited from male non-blood relatives of cases and from husbands of women participating in the Generations cohort study of breast cancer etiology.
 

Raised risk with history of male infertility

Overall, 112 cases (5.6%) and 80 controls (5.0%) reported that they had had infertility problems for which they or their partner had consulted a doctor or infertility clinic. This represented a raised odds ratio of 1.29 (95% confidence interval, 0.94-1.77), which was statistically not significant. However, when analyzed by outcome of the infertility consultation, there was a significant and more than doubled risk of breast cancer among men who were diagnosed as the source of the couple’s infertility (OR = 2.03 [1.18-3.49]), whereas this was not the case among men whose partner was the source (OR = 0.86 [0.51-1.45]) or for whom no source was identified (OR = 1.26 [0.71-2.24]).

In addition, proportionately fewer cases (1,615, or 80.8%) compared with controls (1,423, or 89.1%) had fathered any children, also giving a statistically significantly raised risk of breast cancer for men with no biological children (OR = 1.50 [1.21-1.86], P < .001), “congruent with infertility as a risk factor,” the authors said. The risk was statistically significant for invasive tumors but not for the much smaller number of in situ tumors.

Analysis by number of children showed a decreasing risk with increasing numbers of children, with a highly significant (P < .001) inverse trend where zero was included as a value, but a borderline significant trend (P = .04) if it was not. The team noted that number of children beyond one is difficult to interpret as an indicator of male fertility, since it may more reflect social and cultural factors than fertility per se.

Baseline demographic factors were adjusted for in the risk analyses, and results were not materially changed by sensitivity analyses adjusting additionally for alcohol consumption, smoking, liver disease, and family history of breast cancer. The association also largely remained after exclusion of patients with other preexisting potential confounders including severe obesity and testicular abnormalities, and was consistent irrespective of HER-2 status (there were too few ER-negative tumors to analyze results by ER status).
 

Potential underlying factors

“The causes of breast cancer in men are largely unknown, partly because it is rare and partly because previous studies have been small,” Dr. Jones said. “The evidence presented in our study suggests that the association of infertility and breast cancer should be confirmed with further research, and future investigations are needed into the potential underlying factors, such as hormone imbalances.”

Commenting on the study, Fiona Osgun, senior health information manager at Cancer Research UK, told this news organization: “Overall, there isn’t strong evidence that infertility is a risk factor for male breast cancer. This study helps to shed light onto a cancer type that is sadly still not very well understood, but much more research is needed to say that infertility is a risk factor for male breast cancer.”

She added that although male breast cancer is a rare condition, it’s still important for men to be aware of what looks and feels normal for them, and to be encouraged to seek medical advice if something is not quite right.

A spokesperson for Breast Cancer UK told this news organization: “[We] believe it’s important to understand what leads to breast cancer in men as well as women and that high quality, long-term studies such as this will help with this understanding.

The findings are consistent with an earlier study that found that U.S. men who have never fathered children are at higher risk of breast cancer. This new long-term U.K. study provides strong evidence, which supports this finding.  

“As the authors note, the biological reasons are unclear, but may be associated with altered hormone levels. The ratio of circulating levels of estrogen and androgens (e.g. testosterone) is crucial in healthy functioning of breast tissue. Disruption to this, for example as a result of damage to testes, may affect both fertility and breast cancer risk.

“It is also possible that external factors, such as exposure to certain endocrine (hormone) disrupting chemicals (EDCs), which affect sex hormones, may also affect both fertility and breast cancer risk.

“More studies into breast cancer in men are needed to help us understand better all the risk factors associated with this disease including both hormonal factors and chemical exposures.”

Simon Vincent, PhD, director of research, support, and influencing at Breast Cancer Now, said: “Research has discovered different treatments directed at some features of breast cancer in women; however, breast cancer is not as well understood for men. This is why Breast Cancer Now funds the Male Breast Cancer Study, which looks at what might cause the disease in men. Discovering a link between infertility and male breast cancer is a step towards us understanding male breast cancer and how we could find more ways to diagnose and treat men – and possibly women – with this devastating disease.”

That Toxoplasma gondii looks good on you

Parasite and attractiveness don’t usually go together, but it appears that nobody told Toxoplasma gondii. The world’s most successful parasite affects 30%-50% of the world’s population, and it’s mainly thought to go after the brain in humans, possibly changing behavior and leading to neurological disorders and mental illness.

Now, are you ready to be super confused? According to a recent study, those affected with T. gondii were seen as more attractive and healthy looking, compared with noninfected people. It doesn’t make much sense to us, but it could be an evolutionary thing: The more attractive the parasite makes a person or animal, the more likely it is to spread.

“Some sexually transmitted parasites, such as T. gondii, may produce changes in the appearance and behavior of the human host, either as a by-product of the infection or as the result of the manipulation of the parasite to increase its spread to new hosts,” Javier Borráz-León, PhD, of the University of Turku (Finland), and associates wrote in PeerJ.

Previous research has suggested that men with more testosterone are more likely to become infected because of their behavior with the extra hormones. It’s also been noted that the parasite may manipulate hormones for its own gain, but that’s not proven. Infected women were found to have a lower BMI, more confidence in their appearance, and more partners. Dr. Borráz-León and associates also found that “Toxoplasma-infected subjects had significantly lower facial fluctuating asymmetry than the noninfected people,” ScienceAlert said.

We usually perceive parasites as a bad thing, but honestly this one isn’t sounding too bad. It seems to help with some confidence boosters, and who doesn’t want that? We’re thinking that T. gondii could be the Next Big Thing. All it needs is some marketing and … what if it was covered with nonpareils?

Give it to me straight, Doc. Don’t sugar coat it.

Okay, so he’s not a doctor – not a medical doctor, anyway – but that’s exactly what he did. William H. Grover, PhD, has sugar coated drugs in the name of fraud prevention. We will explain.

The sugar coating comes in the form of nonpareils, the tiny and colorful round sprinkles often found covering small discs of chocolate. Dr. Grover, a bioengineering professor at the University of California, Riverside, who has been working on ways to ensure the authenticity of pharmaceuticals, “started wondering how many different patterns of colored nonpareils were possible on these candies,” he said in a statement from the university.

With just eight colors and an average of 92 individual nonpareils on each candy, the combinations, he found out, are almost endless. Could the same thing be done with a pill? Could the nonpareils be applied as a coating to a pill, giving it a unique pattern that could be stored by the manufacturer and used later as identification?

After much time and effort involving edible cake-decorating glue, Tylenol capsules, smartphones, and computer simulations, he produced CandyCode, an algorithm that converts a photo of a nonpareil-covered pill “into a set of text strings suitable for storing in a computer database and querying by consumers,” the statement explained.

Dr. Grover also mentioned a side benefit: “Anecdotally, I found that CandyCoded caplets were more pleasant to swallow than plain caplets, confirming Mary Poppins’ classic observation about the relationship between sugar and medicine.”

First of all, we can’t believe we just used a Mary Poppins reference. Not exactly what you’d call MDedgey, is it? Second of all, what about the children? We’re talking about drugs that, literally, have been turned into candy. Are the kids going to love them, too? Sounds more like a job for Mr. Yuk.
 

So you want to be a superhero?

Be honest, who didn’t want to be a superhero when they were a kid? There’s a reason every other movie released in the past decade has been a superhero movie. That’s how we’ve ended up with the millionth Batman reboot and Marvel scraping the bottom of the C-list hero barrel. (Seriously, who’d actually heard of Moon Knight before now?)

rudall30/iStockphoto.com

Point is, we all like to fantasize, and now a meta-analysis from researchers in Germany and the United States has given us all a reason to strike those dashing superhero poses. Through evaluation of 130 studies and over 10,000 people, the researchers found that power posing (and perfect posture) was strongly associated with increased confidence and self-worth. It was also associated with improved behavior, though the connection was less strong.

Sadly though, the research found no connection with power posing and changes in testosterone or cortisol levels. Standing like a superhero may make you feel good, but it won’t give your body any cool powers or superhuman abilities. But don’t despair, because we’re not finished yet. In fact, it may be the biggest news we’ve ever reported for LOTME: A group of scientists from the University of Kentucky has assembled the full genome of a salamander.

Wait, we have more! Beyond having a genome ten times bigger than a human, this salamander, the axolotl from Mexico, is the model of natural regeneration. Name a body part, and the axolotl can grow it back. It can even regenerate portions of its brain. And now that we have access to the complete genome, it’s possible that one day we could use the axolotl’s regeneration for ourselves. Growing back limbs, regenerating spinal cords, the sky’s the limit. And if Wolverine and Deadpool are anything to go by, it’s all you need to get that superhero career off the ground. Salamander powers may not have the cachet of a radioactive spider, but we’ll take what we can get.
 

Post your way to financial hardship

After you pump your gas at the gas station, how do you pay? At the pump or inside? How frequently do you post to your social media pages? What kind of content are you posting?

That kind of nontraditional credit data hasn’t been considered by lenders and credit agencies, but that is changing. The reasoning? It’s opening more opportunities for those without much credit history. But according to a paper published by Janine S. Hiller of Virginia Tech and Lindsay Sain Jones, a financial regulation researcher at the University of Georgia, this just opens a can of worms.

Why is this so dangerous? Well, alternative credit scoring isn’t covered by the Fair Credit Reporting Act or Equal Opportunity Act, so the consumer doesn’t have the ability to dispute any data the credit agencies or lenders receive. Then there’s the “credit boost,” which some companies offer to gain access to the consumer’s data. Often there are no limitations on how long it’s kept. That purchase you made 2 years ago can come back to haunt you.

It also creates a cause for the possibility of discrimination based on “lifestyle-related data points,” which some lenders use to determine creditworthiness: zip code, age, gender, race, socioeconomic status. Even where the consumer went to college is a factor taken under consideration.

“There are all kinds of factors that can be correlated with creditworthiness, but that doesn’t mean they should be used,” Ms. Jones said in the EurekAlert statement.

Let’s say someone applies for a loan needed for a medical procedure. They could be denied because the lender or a credit-reporting agency didn’t like the data they received (most times without the consumer’s consent). Talk about a broken system.

It also creates a cause for the possibility of discrimination based on “lifestyle-related data points,” which some lenders use to determine creditworthiness: zip code, age, gender, race, socioeconomic status. Even where the consumer went to college is a factor taken under consideration.

“There are all kinds of factors that can be correlated with creditworthiness, but that doesn’t mean they should be used,” Ms. Jones said in the EurekAlert statement.

Let’s say someone applies for a loan needed for a medical procedure. They could be denied because the lender or a credit-reporting agency didn’t like the data they received (most times without the consumer’s consent). Talk about a broken system.
 

“Here and now is what counts. So, let’s go to work!” –Walter Orthmann, 100 years old
 

How long before you retire? If you know the answer in exact years, months, and days, you aren’t alone. For many good reasons, we doctors are more likely to be counting down the years until we retire rather than counting up the years since we started working. For me, if I’m to break the Guinness World Record, I have 69 more years, 3 months and 6 days left to go. That would surpass the current achievement for the longest career at one company, Mr. Walter Orthmann, who has been sitting at the same desk for 84 years. At 100 years old, Mr. Orthmann still shows up every Monday morning, as bright eyed and bushy tailed as a young squirrel. I’ll be 119 when I break his streak, which would also put me past Anthony Mancinelli, a New York barber who at 107 years of age was still brushing off his chair for the next customer. Unbelievable, I know! I wonder, what’s the one weird trick these guys are doing that keeps them going?

Guinness World Records

Of course, the job itself matters. Some jobs, like being a police officer, aren’t suitable for old people. Or are they? Officer L.C. “Buckshot” Smith was still keeping streets safe from his patrol car at 91 years old. After a bit of searching, I found pretty much any job you can think of has a very long-lasting Energizer Bunny story: A female surgeon who was operating at 90 years old, a 100-year-old rheumatologist who was still teaching at University of California, San Francisco, and a 105-year-old Japanese physician who was still seeing patients. There are plenty of geriatric lawyers, nurses, land surveyors, accountants, judges, you name it. So it seems it’s not the work, but the worker that matters. Why do some older workers recharge daily and carry on while many younger ones say the daily grind is burning them out? What makes the Greatest Generation so great?

We all know colleagues who hung up their white coats early. In my medical group, it’s often financially feasible to retire at 58 and many have chosen that option. Yet, we have loads of Partner Emeritus docs in their 70’s who still log on to EPIC and pitch in everyday.

“So, how do you keep going?” I asked my 105-year-old patient who still walks and manages his affairs. “Just stay healthy,” he advised. A circular argument, yet he’s right. You must both be lucky and also choose to be active mentally and physically. Mr. Mancinelli, who was barbering full time at 107 years old, had no aches and pains and all his teeth. He pruned his own bushes. The data are crystal clear that physical activity adds not only years of life, but also improves cognitive capabilities during those years.

As for beating burnout, it seems the one trick that these ultraworkers do is to focus only on the present. Mr. Orthmann’s pithy advice as quoted by NPR is, “You need to get busy with the present, not the past or the future.” These centenarian employees also frame their work not as stressful but rather as their daily series of problems to be solved.

When I asked my super-geriatric patient how he sleeps so well, he said, “I never worry when I get into bed, I just shut my eyes and sleep. I’ll think about tomorrow when I wake up.” Now if I can do that about 25,000 more times, I’ll have the record.
