If one word describes Eladio (“Lad”) Braganza, age 77, it’s “tenacious.” For 28 days, he clung to life on a ventilator in a Seattle ICU. Now – after a 46-day hospitalization for SARS-CoV-2 infection – he’s making progress in inpatient rehab, determined to regain function.

“We were not sure if he was going to make it through his first night in the hospital, and for a while after that. We were really prepared that he would not survive his ventilator time,” his daughter, Maria Braganza, said in an interview just 5 days after her father had been transferred to inpatient rehab.

In many ways, Mr. Braganza’s experience is typical of seriously ill COVID-19 patients. Many go from walking and talking to being on a ventilator within 10 hours or less. Mr. Braganza was admitted to the hospital on March 21 and was intubated that day. To keep him on the ventilator, he was heavily sedated and unconscious at times. In the ICU, he experienced bouts of low blood pressure, a pattern of shock that occurs in COVID-19 patients and that does not always respond to fluids.

Doctors have quickly learned to treat these patients aggressively. Many patients in the ICU with COVID-19 develop an inflamed, atypical form of acute respiratory distress syndrome (ARDS), in which the lung’s compliance, or stiffness, does not match the severity of hypoxia. These patients require high levels of oxygen and high ventilator settings. Many develop pneumothorax, or collapsed lungs, because of the high pressures needed to deliver oxygen and the prolonged time on ventilation.

“The vast majority of COVID patients in the ICU have lung disease that is quite severe, much more severe than I have seen in my 20 years of doing this,” said critical care specialist Anna Nolan, MD, of the department of medicine at New York University.

After about 2 weeks, some of these patients can come off the ventilator, or they may undergo a tracheostomy, a hole in the neck through which a tube is placed to deliver oxygen. By this time, many have developed ICU-acquired weakness and muscle wasting. Some may be so debilitated that they cannot walk. Even the respiratory muscles that help them breathe may have weakened as a result of the ventilator doing the work for them.

These patients “get sick very fast, and it takes a long time for them to heal. What’s not really well appreciated is how much rehab and how much recovery time these patients are going to need,” said David Chong, MD. He is medical director of the ICU at New York–Presbyterian Hospital/Columbia University Medical Center, and he has been on the front lines during the COVID-19 surge in New York City.

The road to recovery

Regardless of the cause, many people who have a prolonged stint in the ICU face an even longer convalescence. Still-unanswered questions concern whether recovery time will be longer for those with COVID-19, compared with other illnesses, and whether some of the damage may be permanent. A number of small studies in Hong Kong and China, as well as studies of severe acute respiratory syndrome patients’ recoveries, have promoted speculation about possible long-lasting damage to lungs and other organs from COVID-19.

Yet some of these reports have left out important details about ARDS in COVID-19 patients who also may be most at risk for long-lasting damage. To clear up some of the confusion, the Pulmonary Fibrosis Foundation said on April 6 that some but not all of COVID-19 patients who develop ARDS may go on to develop lung fibrosis – scarring of the lungs – which may be permanent.

“Post-ARDS fibrosis typically is not progressive, but nonetheless can be severe and limiting. The recovery period for post-ARDS fibrosis is approximately 1 year and the residual deficits persist, but generally do not progress,” the foundation noted.

Emerging research on lung damage in COVID-19

Because the pandemic is only a few months in, it’s unclear as yet what the long-term consequences of severe COVID-19 may be. But emerging data are enabling researchers to venture an educated guess about what may happen in the months and years ahead.

The key to understanding the data is knowing that ARDS is a syndrome – the end product of a variety of diseases or insults to the lung. Under the microscope, lung damage from ARDS associated with COVID-19 is indistinguishable from lung damage resulting from other causes, such as vaping, sepsis, or shock caused by a motor vehicle accident, said Sanjay Mukhopadhyay, MD, director of pulmonary pathology at Cleveland Clinic.

Dr. Mukhopadhyay, who specializes in lung pathology, performed one of the first complete autopsies of a COVID-19 patient in the United States. In most autopsy series published to date, he said, the most common lung finding in patients who have died from COVID-19 is diffuse alveolar damage (DAD), a pattern of lung injury seen in ARDS from many other causes.

In DAD, the walls of the alveoli – thinly lined air sacs that facilitate gas exchange in the lung – develop a pink, hyaline membrane composed of damaged cells and plasma proteins that leak from capillaries in the wall of the alveolus. This hyaline membrane gets plastered against the wall of the alveolus and interferes with diffusion of oxygen into the body.

“We know what happens in ARDS from other causes. If you follow people who have been on a ventilator long term, some of their respiratory function goes back to normal,” Dr. Mukhopadhyay said. “But there are other people in whom some degree of respiratory impairment lingers. In these patients, we think the DAD progresses to an organizing stage.”

Organizing pneumonia refers to a family of diseases in which fibroblasts (cells involved in wound healing) arrive and form scar tissue that forms hyaline membranes and fibrin balls (tough proteins) that fill up the alveoli, making gas exchange very difficult.

Also called BOOP (bronchiolitis obliterans organizing pneumonia), this condition is sensitive to steroids. Early aggressive steroid treatment can prevent long-term lung damage. Without steroids, damage can become permanent. A variant of this condition is termed acute fibrinous and organizing pneumonia (AFOP), which is also sensitive to steroids. A report from France demonstrates AFOP in some patients who have died from COVID-19.

The trick is identifying who is developing BOOP and who is not, and beyond that, who might be most amenable to treatment. Use of steroids for patients with certain other problems, such as a bacterial infection on top of COVID-19, could be harmful. David H. Chong, MD, and colleagues at Columbia University Irving Medical Center, New York, are investigating this to determine which COVID-19 patients may benefit from early steroid therapy.

“It’s not clear if there is a predominant histologic type or if we are catching people at different phases of their disease, and therefore we’re seeing different lung pathology,” Dr. Chong said.

He thinks that many patients with severe COVID-19 probably will not develop this pattern of lung scarring. “We’re speculating that lung damage from severe COVID-19 is probably going to behave more like lung damage from regular ARDS, which is often reversible. We think the vast majority of these patients probably have DAD that is similar to most patients with ARDS from other etiologies,” Dr. Chong said.

That would be consistent with information from China. In an April interview with Chinese domestic media, Zhong Nanshan, MD, a pulmonologist at the head of China’s COVID-19 task force, stated that he expects that the lungs in most patients with COVID-19 will gradually recover. He was responding to a widely publicized small study that found evidence of residual lung abnormalities at hospital discharge in most patients (94%, 66/70) who suffered from COVID-19 pneumonia in Wuhan, China, from January to February 2020.

Tough research conditions

Experts say that follow-up in this Chinese study and others to date has not been nearly long enough to allow predictions about lasting lung damage in COVID-19.

They also highlight the tough conditions in which researchers are working. Few autopsies have been performed so far – autopsies take time, extra precautions must be taken to avoid spread of COVID-19, and many patients and families do not consent to an autopsy. Furthermore, autopsy data from patients who died of COVID-19 may not extrapolate to survivors.

“I would not hang my hat on any of the limited data I have seen on autopsies,” said Lina Miyakawa, MD, a critical care and pulmonary medicine specialist at Mount Sinai Hospital in New York City.

“Even though we have answers about how the lungs are damaged at the end stage, this does not elucidate any answers about the earlier lung damage from this disease,” she continued. “It would be informative to have pathological data from the early or transitional phase, to see if that may translate into a treatment modality for COVID-19 patients.”

The problem is that these patients often experience a large amount of sloughing of airway cells, along with mucous plugging (collections of mucous that can block airflow and collapse alveoli). Bronchoscopy, which is used to view the inside of the lungs and sometimes to retrieve biopsy specimens for microscopic evaluation, is too risky for many COVID-19 patients.

In addition, few CT data exist for severely ill COVID-19 patients, who can be so unstable that to transport them to undergo a CT scan can be dangerous, not to mention the concern regarding infection control.

Even if sufficient data did exist, findings from chest x-rays, CTs, pathology studies, and lung function tests do not always match up. A patient who has lung abnormalities on CT may not necessarily have clinically impaired lung function or abnormal pathologic findings, according to Ali Gholamrezanezhad, MD, an emergency radiologist who is with the department of clinical radiology at the University of Southern California, Los Angeles.

Together with colleagues at USC, Dr. Gholamrezanezhad has started a long-term study of patients who were hospitalized with COVID-19. The researchers will follow patients for at least 1 year and will use chest x-ray, chest CT, and exercise testing to evaluate lung recovery over time.

“In the acute phase, we have acute inflammation called ground glass opacities, which usually happen bilaterally in COVID-19. That is totally reversible damage that can return to normal with no scarring,” Dr. Gholamrezanezhad said.

On the basis of data from survivors of other severe pneumonias, such as Middle East respiratory syndrome, SARS-CoV-1 infection, and H1N1 influenza, Gholamrezanezhad thinks that most survivors of COVID-19 will be able to return to work and normal life, although some may show residual lung dysfunction. Age, underlying medical conditions, smoking, length of hospital stay, severity of illness, and quality of treatment may all play a role in how well these people recover.

The lung has a remarkable capacity to recover, he added. Critical illness can destroy type one pneumocytes — the cells that line the alveoli in the lung — but over time, these cells grow back and reline the lungs. When they do, they can also help repair the lungs.

On top of that, the lung has a large functional reserve, and when one section becomes damaged, the rest of the lung can compensate.

However, for some people, total maximum exercise capacity may be affected, he commented.

Mukhopadhyay said: “My feeling is you will get reversal to normal in some patients and you will get long-term fibrosis from ARDS in some survivors. The question is, how many will have complete resolution and how many will have fibrosis? To know the answer, we will need a lot more data than we have now.”

Convalescence of COVID-19 Patients

Like many who become seriously ill with COVID-19, Braganza had underlying medical problems. Before becoming ill, he had had a heart attack and stroke. He walked with a walker and had some age-related memory problems.

Five days after transfer to inpatient rehab, Braganza was walking up and down the hallway using a walker. He was still shaking off the effects of being heavily sedated for so long, and he experienced periods of confusion. When he first came off the ventilator, he mixed up days and nights. Sometimes he did not remember being so sick. A former software engineer, Braganza usually had no problem using technology, but he has had to relearn how to use his phone and connect his iPad to Wi-Fi.

“He is still struggling quite a bit with remembering how to do basic things,” Maria Braganza said. “He has times of being really depressed because he feels like he’s not making progress.”

Doctors are taking note and starting to think about what lies ahead for ICU survivors of COVID-19. They worry about the potential for disease recurrence as well as readmission for other problems, such as other infections and hip fractures.

“As COVID-19 survivors begin to recover, there will be a large burden of chronic critical illness. We expect a significant need for rehabilitation in most ICU survivors of COVID-19,” said Steve Lubinsky, MD, medical director of respiratory care at New York University Langone Tisch Hospital.

Thinking about her father, Maria Braganza brings an extra dimension to these concerns. She thinks about depression, loneliness, and social isolation among older survivors of COVID-19. These problems existed long before the pandemic, but COVID-19 has magnified them.

The rehab staff estimates that Mr. Braganza will spend 10-14 days in their program, but discharge home creates a conundrum. Before becoming ill, Mr. Braganza lived in an independent senior living facility. Now, because of social distancing, he will no longer be able to hang out and have meals with his friends.

“Dad’s already feeling really lonely in the hospital. If we stay on a semipermanent lockdown, will he be able to see the people he loves?” Maria Braganza said. “Even though somebody is older, they have a lot to give and a lot of experience. They just need a little extra to be able to have that life.”

Dr. Nolan, Dr. Chong, Dr. Mukhopadhyay, Dr. Miyakawa, Dr. Gholamrezanezhad, and Dr. Lubinsky report no relevant financial relationships.

Furthermore, autopsy data from patients who died of COVID-19 may not extrapolate to survivors.

“I would not hang my hat on any of the limited data I have seen on autopsies,” said Lina Miyakawa, MD, a critical care and pulmonary medicine specialist at Mount Sinai Hospital in New York City.

“Even though we have answers about how the lungs are damaged at the end stage, this does not elucidate any answers about the earlier lung damage from this disease,” she continued. “It would be informative to have pathological data from the early or transitional phase, to see if that may translate into a treatment modality for COVID-19 patients.”

The problem is that these patients often experience a large amount of sloughing of airway cells, along with mucous plugging (collections of mucous that can block airflow and collapse alveoli). Bronchoscopy, which is used to view the inside of the lungs and sometimes to retrieve biopsy specimens for microscopic evaluation, is too risky for many COVID-19 patients.

In addition, few CT data exist for severely ill COVID-19 patients, who can be so unstable that to transport them to undergo a CT scan can be dangerous, not to mention the concern regarding infection control.

Even if sufficient data did exist, findings from chest x-rays, CTs, pathology studies, and lung function tests do not always match up. A patient who has lung abnormalities on CT may not necessarily have clinically impaired lung function or abnormal pathologic findings, according to Ali Gholamrezanezhad, MD, an emergency radiologist who is with the department of clinical radiology at the University of Southern California, Los Angeles.

Together with colleagues at USC, Dr. Gholamrezanezhad has started a long-term study of patients who were hospitalized with COVID-19. The researchers will follow patients for at least 1 year and will use chest x-ray, chest CT, and exercise testing to evaluate lung recovery over time.

“In the acute phase, we have acute inflammation called ground glass opacities, which usually happen bilaterally in COVID-19. That is totally reversible damage that can return to normal with no scarring,” Dr. Gholamrezanezhad said.

On the basis of data from survivors of other severe pneumonias, such as Middle East respiratory syndrome, SARS-CoV-1 infection, and H1N1 influenza, Gholamrezanezhad thinks that most survivors of COVID-19 will be able to return to work and normal life, although some may show residual lung dysfunction. Age, underlying medical conditions, smoking, length of hospital stay, severity of illness, and quality of treatment may all play a role in how well these people recover.

The lung has a remarkable capacity to recover, he added. Critical illness can destroy type one pneumocytes — the cells that line the alveoli in the lung — but over time, these cells grow back and reline the lungs. When they do, they can also help repair the lungs.

On top of that, the lung has a large functional reserve, and when one section becomes damaged, the rest of the lung can compensate.

However, for some people, total maximum exercise capacity may be affected, he commented.

Mukhopadhyay said: “My feeling is you will get reversal to normal in some patients and you will get long-term fibrosis from ARDS in some survivors. The question is, how many will have complete resolution and how many will have fibrosis? To know the answer, we will need a lot more data than we have now.”

Convalescence of COVID-19 Patients

Like many who become seriously ill with COVID-19, Braganza had underlying medical problems. Before becoming ill, he had had a heart attack and stroke. He walked with a walker and had some age-related memory problems.

Five days after transfer to inpatient rehab, Braganza was walking up and down the hallway using a walker. He was still shaking off the effects of being heavily sedated for so long, and he experienced periods of confusion. When he first came off the ventilator, he mixed up days and nights. Sometimes he did not remember being so sick. A former software engineer, Braganza usually had no problem using technology, but he has had to relearn how to use his phone and connect his iPad to Wi-Fi.

“He is still struggling quite a bit with remembering how to do basic things,” Maria Braganza said. “He has times of being really depressed because he feels like he’s not making progress.”

Doctors are taking note and starting to think about what lies ahead for ICU survivors of COVID-19. They worry about the potential for disease recurrence as well as readmission for other problems, such as other infections and hip fractures.

“As COVID-19 survivors begin to recover, there will be a large burden of chronic critical illness. We expect a significant need for rehabilitation in most ICU survivors of COVID-19,” said Steve Lubinsky, MD, medical director of respiratory care at New York University Langone Tisch Hospital.

Thinking about her father, Maria Braganza brings an extra dimension to these concerns. She thinks about depression, loneliness, and social isolation among older survivors of COVID-19. These problems existed long before the pandemic, but COVID-19 has magnified them.

The rehab staff estimates that Mr. Braganza will spend 10-14 days in their program, but discharge home creates a conundrum. Before becoming ill, Mr. Braganza lived in an independent senior living facility. Now, because of social distancing, he will no longer be able to hang out and have meals with his friends.

“Dad’s already feeling really lonely in the hospital. If we stay on a semipermanent lockdown, will he be able to see the people he loves?” Maria Braganza said. “Even though somebody is older, they have a lot to give and a lot of experience. They just need a little extra to be able to have that life.”

Dr. Nolan, Dr. Chong, Dr. Mukhopadhyay, Dr. Miyakawa, Dr. Gholamrezanezhad, and Dr. Lubinsky report no relevant financial relationships.

The American Diabetes Association has dedicated a whole section of its journal, Diabetes Care, to the topic of “Diabetes and COVID-19,” publishing a range of articles with new data to help guide physicians in caring for patients.

“Certain groups are more vulnerable to COVID-19, notably older people and those with underlying medical conditions. Because diabetes is one of the conditions associated with high risk, the diabetes community urgently needs to know more about COVID-19 and its effects on people with diabetes,” an introductory commentary noted.

Entitled “COVID-19 in people with diabetes: Urgently needed lessons from early reports,” the commentary is penned by the journal’s editor-in-chief, Matthew Riddle, MD, of Oregon Health & Science University, Portland, and colleagues.

Also writing in the same issue, William T. Cefalu, MD, and colleagues from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) noted it is known that the SARS-CoV-2 virus enters cells via the angiotensin-converting enzyme 2 (ACE-2) receptor. The ACE-2 receptor is known to be in the lungs and upper respiratory tract, “but we also know that it is expressed in other tissues such as heart, small and large intestines, and pancreas,” they wrote, and also “in the kidney.”

Hence, there are emerging reports of acute kidney injury resulting from COVID-19, as well as the impact on many other endocrine/metabolic and gastrointestinal outcomes.

“Pilot clinical studies (observational and interventional) are needed that will support the understanding or treatment of COVID-19–related diseases within the mission of the NIDDK,” they stated.
 

Although rapidly collected, data “offer important clues”

Some of the new ground covered in the journal articles includes an analysis of COVID-19 outcomes by type of glucose-lowering medication; remote glucose monitoring in hospitalized patients with COVID-19; a suggested approach to cardiovascular risk management in the COVID-19 era, as already reported by Medscape Medical News; and the diagnosis and management of gestational diabetes during the pandemic.

Other articles provide new data for previously reported phenomena, including obesity as a risk factor for worse COVID-19 outcomes and the role of inpatient glycemic control on COVID-19 outcomes.

“The data reported in these articles were rapidly collected and analyzed, in most cases under urgent and stressful conditions,” Dr. Riddle and colleagues cautioned. “Thus, some of the analyses are understandably limited due to missing data, incomplete follow-up, and inability to identify infected but asymptomatic patients.”

Even so, they wrote, some points are clear. “The consistency of findings in these rapidly published reports is reassuring in terms of scientific validity, but the story unfolding is worrisome.”

Specifically, while diabetes does not appear to increase the likelihood of SARS-CoV-2 infection, progression to severe illness is more likely in people with diabetes and COVID-19: They are two to three times as likely to require intensive care, and to die, compared with those infected but without diabetes.

“Neither the mechanisms underlying the increased risk nor the best interventions to limit it have yet been defined, but the studies in this collection of articles offer important clues,” Dr. Riddle and colleagues wrote.
 

Existing insulin use linked to COVID-19 death risk

One of the articles is a retrospective study of 904 hospitalized COVID-19 patients by Yuchen Chen, MD, of the Huazhong University of Science and Technology, Wuhan, China, and colleagues.

Among the 136 patients with diabetes, risk factors for mortality included older age (adjusted odds ratio, 1.09 per year increase; P = .001) elevated C-reactive protein (aOR, 1.12; P = .043), and insulin use (aOR, 3.58; P = .009).

“Attention needs to be paid to patients with diabetes and COVID-19 who use insulin,” the Chinese authors wrote. “Whether this was due to effects of insulin itself or to characteristics of the patients for whom it was prescribed is not clear,” Dr. Riddle and colleagues noted.

Dr. Chen and colleagues also found no difference in clinical outcomes between those diabetes patients with COVID-19 who were taking an ACE inhibitor or angiotensin II type I receptor blocker, compared with those who did not, which supports existing recommendations to continue use of this type of medication.
 

Remote glucose monitoring a novel tool for COVID-19 isolation

Another publication, by Gilat Shehav-Zaltzman of Sheba Medical Center, Tel Hashomer, Israel, and colleagues, describes the use of remote continuous glucose monitoring (CGM) in two hospitalized COVID-19 patients who were in isolation – one with type 1 diabetes and the other with type 2 diabetes – treated with basal-bolus insulin.

Using Medtronic CGM systems, the hospital staff was able to view patients’ real-time data uploaded to the Web from computer terminals in virus-free areas outside the patients’ rooms. The hospital’s endocrinology team had trained the intensive care staff on how to replace the sensors weekly and calibrate them twice daily.

“Converting a personal CGM system originally designed for diabetes self-management to team-based, real-time remote glucose monitoring offers a novel tool for inpatient diabetes control in COVID-19 isolation facilities,” the authors wrote.

“Such a solution in addition to ongoing remotely monitored clinical parameters (such as pulse rate, electrocardiogram, and oxygen saturation) adds to quality of diabetes care while minimizing risk of staff exposure and burden,” they observed.

Dr. Riddle and colleagues concurred: “Newer methods of remotely monitoring glucose patterns could be uniquely helpful.”

Key question: Does glycemic management make a difference?

With regard to the important issue of in-hospital control of glucose, Celestino Sardu, MD, PhD, of the University of Campania Luigi Vanvitelli, Naples, Italy, and colleagues reported on 59 patients hospitalized with confirmed COVID-19 and moderately severe pneumonia.

They were categorized as normoglycemic (n = 34) or hyperglycemic (n = 25), as well as with or without diabetes, on the basis of a diagnosis preceding the current illness. Of the 25 patients with hyperglycemia, 15 patients were treated with insulin infusion and 10 patients were not.

In a risk-adjusted analysis, both patients with hyperglycemia and patients with diabetes had a higher risk of severe disease than did those without diabetes and with normoglycemia. Patients with hyperglycemia treated with insulin infusion had a lower risk of severe disease than did patients who didn’t receive an insulin infusion.

And although they noted limitations, the authors wrote, “Our data evidenced that optimal glucose control in the immediate postadmission period for almost 18 days was associated with a significant reduction of inflammatory cytokines and procoagulative status.”

Dr. Riddle and colleagues wrote that the findings of this unrandomized comparison were interpreted “as suggesting that insulin infusion may improve outcomes.”

“If the benefits of seeking excellent glycemic control by this means are confirmed, close monitoring of glucose levels will be essential.”
 

More on obesity and COVID-19, this time from China

Because it has become increasingly clear that obesity is a risk factor for severe COVID-19, new data from China – where this was less apparent initially – support observations in Europe and the United States.

An article by Qingxian Cai, PhD, of Southern University of Science and Technology, Shenzhen, Guangdong, China, and colleagues looks at this. They found that, among 383 hospitalized patients with COVID-19, the 41 patients with obesity (defined as a body mass index ≥ 28 kg/m²) were significantly more likely to progress to severe disease compared with the 203 patients classified as having normal weight (BMI, 18.5-23.9), with an odds ratio of 3.4.

A similar finding comes from Feng Gao, MD, PhD, of the First Affiliated Hospital of Wenzhou (China) Medical University and colleagues, who studied 75 patients hospitalized with confirmed COVID-19 and obesity (defined as a BMI > 25 in this Asian population) to 75 patients without obesity matched by age and sex. After adjustment for clinical characteristics including the presence of diabetes, those with obesity had a threefold greater risk of progression to severe or critical COVID-19 status, with a nearly linear relationship.
 

Emerging from the crisis: Protect the vulnerable, increase knowledge base

As the research community emerges from the crisis, “there should be renewed efforts for multidisciplinary research ... aimed at greatly increasing the knowledge base to understand how ... the current COVID-19 threat” affects “both healthy people and people with chronic diseases and conditions,” Dr. Cefalu and colleagues concluded in their commentary.

Dr. Riddle and coauthors agreed: “We will enter a longer interval in which we must continue to support the most vulnerable populations – especially older people, those with diabetes or obesity, and those who lack the resources to limit day-to-day exposure to infection. We hope a growing sense of community will help in this task.”

Dr. Riddle has reported receiving research grant support through Oregon Health & Science University from AstraZeneca, Eli Lilly, and Novo Nordisk, and honoraria for consulting from Adocia, AstraZeneca, Eli Lilly, GlaxoSmithKline, Novo Nordisk, Sanofi, and Theracos. Dr. Cefalu has reported no relevant financial relationships.

Children with COVID-19 are more likely to develop severe illness and require intensive care than previously realized, data from a single-center study suggest.

Jerry Y. Chao, MD, of the department of anesthesiology, Albert Einstein College of Medicine, New York, and colleagues reported their findings in an article published online May 11 in the Journal of Pediatrics.

“Thankfully most children with COVID-19 fare well, and some do not have any symptoms at all, but this research is a sobering reminder that children are not immune to this virus and some do require a higher level of care,” senior author Shivanand S. Medar, MD, FAAP, attending physician, Cardiac Intensive Care, Children’s Hospital at Montefiore, and assistant professor of pediatrics, Albert Einstein College of Medicine, said in a Montefiore Medical Center news release.

The study included 67 patients aged 1 month to 21 years (median, 13.1 years) who were treated for COVID-19 at a tertiary care children’s hospital between March 15 and April 13. Of those, 21 (31.3%) were treated as outpatients.

“As the number of patients screened for COVID-19 was restricted during the first weeks of the outbreak because of limited testing availability, the number of mildly symptomatic patients is not known, and therefore these 21 patients are not included in the analysis,” the authors wrote.

Of the 46 hospitalized patients, 33 (72%) were admitted to a general pediatric medical ward, and 13 (28%) were admitted to the pediatric intensive care unit (PICU).

Almost one-third (14 children; 30.4%) of the admitted patients were obese, and almost one-quarter (11 children; 24.4%) had asthma, but neither factor was associated with an increased risk for PICU admission.

“We know that in adults, obesity is a risk factor for more severe disease, however, surprisingly, our study found that children admitted to the intensive care unit did not have a higher prevalence of obesity than those on the general unit,” Dr. Chao said in the news release.

Three of the PICU patients (25%) had preexisting seizure disorders, as did one (3%) patient on the general medical unit. “There was no significant difference in the usage of ibuprofen prior to hospitalization among patients admitted to medical unit compared with those admitted to the PICU,” the authors wrote.

Platelet counts were lower in patients admitted to the PICU compared with those on the general medical unit; however, C-reactive protein, procalcitonin, and pro–brain natriuretic peptide levels were all elevated in patients admitted to the PICU compared with those admitted to the general medical unit.

Patients admitted to the PICU were more likely to need high-flow nasal cannula. Ten (77%) patients in the PICU developed acute respiratory distress syndrome (ARDS), and six (46.2%) of them needed “invasive mechanical ventilation for a median of 9 days.”

The only clinical symptom significantly linked to PICU admission was shortness of breath (92.3% vs 30.3%; P < .001).

Eight (61.5%) of the 13 patients treated in the PICU were discharged to home; four (30.7%) were still hospitalized and receiving ventilatory support on day 14. One patient had metastatic cancer and died as a result of the cancer after life-sustaining therapy was withdrawn.

Those admitted to the PICU were more likely to receive treatment with remdesivir via compassionate use compared with those treated in the general medical unit. Seven (53.8%) patients in the PICU developed severe sepsis and septic shock syndromes.

The average hospital stay was 4 days longer for the children admitted to the PICU than for the children admitted to the general medical unit.

Cough (63%) and fever (60.9%) were the most frequently reported symptoms at admission. The median duration of symptoms before admission was 3 days. None of the children had traveled to an area affected by COVID-19 before becoming ill, and only 20 (43.5%) children were confirmed to have had contact with someone with COVID-19. “The lack of a known sick contact reported in our study may have implications for how healthcare providers identify and screen for potential cases,” the authors explained.

Although children are believed to experience milder SARS-CoV-2 illness, these results and those of an earlier study suggest that some pediatric patients develop illness severe enough to require PICU admission. “This subset had significantly higher markers of inflammation (CRP, pro-BNP, procalcitonin) compared with patients in the medical unit. Inflammation likely contributed to the high rate of ARDS we observed, although serum levels of IL-6 and other cytokines linked to ARDS were not determined,” the authors wrote.

A retrospective cohort study found that of 177 children and young adults treated in a single center, patients younger than 1 year and older than 15 years were more likely to become critically ill with COVID-19 (J Pediatr. 2020 May. doi: 10.1016/j.jpeds.2020.05.007).

Each of the two age groups accounted for 32% of the hospitalized patients.

Children with COVID-19 are more likely to develop severe illness and require intensive care than previously realized, data from a single-center study suggest.

Jerry Y. Chao, MD, of the department of anesthesiology, Albert Einstein College of Medicine, New York, and colleagues reported their findings in an article published online May 11 in the Journal of Pediatrics.

“Thankfully most children with COVID-19 fare well, and some do not have any symptoms at all, but this research is a sobering reminder that children are not immune to this virus and some do require a higher level of care,” senior author Shivanand S. Medar, MD, FAAP, attending physician, Cardiac Intensive Care, Children’s Hospital at Montefiore, and assistant professor of pediatrics, Albert Einstein College of Medicine, said in a Montefiore Medical Center news release.

The study included 67 patients aged 1 month to 21 years (median, 13.1 years) who were treated for COVID-19 at a tertiary care children’s hospital between March 15 and April 13. Of those, 21 (31.3%) were treated as outpatients.

“As the number of patients screened for COVID-19 was restricted during the first weeks of the outbreak because of limited testing availability, the number of mildly symptomatic patients is not known, and therefore these 21 patients are not included in the analysis,” the authors wrote.

Of the 46 hospitalized patients, 33 (72%) were admitted to a general pediatric medical ward, and 13 (28%) were admitted to the pediatric intensive care unit (PICU).

Almost one-third (14 children; 30.4%) of the admitted patients were obese, and almost one-quarter (11 children; 24.4%) had asthma, but neither factor was associated with an increased risk for PICU admission.

Adult female survivors of domestic abuse were at least one-third more likely to develop cardiovascular disease, type 2 diabetes mellitus, and all-cause mortality over a short follow-up period, although they did not face a higher risk of hypertension, a new British study finds.

The study, published in the Journal of the American Heart Association, provides more evidence of a link between domestic abuse and poor health, even in younger women.

“The prevalence of domestic abuse is vast, so any increased risk in cardiometabolic disease may translate into a large burden of potentially preventable illness in society,” said study lead author Joht Singh Chandan, PhD, MBBS, of the University of Birmingham (England) and University of Warwick in Coventry, England, in an interview.

The researchers retrospectively tracked primary care patients in the United Kingdom from 1995-2017. They compared 18,547 adult female survivors of domestic abuse with a group of 72,231 other women who were matched to them at baseline by age, body mass index, smoking status, and a measure known as the Townsend deprivation score.

The average age of women in the groups was 37 years plus or minus 13 in the domestic abuse group and 37 years plus or minus 12 in the unexposed group. In both groups, 45% of women smoked; women in the domestic abuse group were more likely to drink excessively (10%), compared with those in the unexposed group (4%).

Researchers followed the women in the domestic abuse group for an average of 2 years and the unexposed group for 3 years. Those in the domestic abuse group were more likely to fall out of the study because they transferred to other medical practices.

Over the study period, 181 women in the domestic abuse group and 644 women in the unexposed group developed cardiovascular disease outcomes (adjusted incidence rate ratio, 1.31; 95% confidence interval, 1.11-1.55; P = .001). They were also more likely to develop type 2 diabetes (adjusted IRR, 1.51; 95% CI, 1.30-1.76; P less than .001) and all-cause mortality (adjusted IRR, 1.44; 95% CI, 1.24-1.67; P less than.001). But there was no increased risk of hypertension (adjusted IRR, 0.99; 95% CI, 0.88-1.12; P = 0.873).

Why might exposure to domestic abuse boost cardiovascular risk? “Although our study was not able to answer exactly why this relationship exists, we believe that it is likely due to the effects of acute and chronic stress caused by [domestic abuse],” Dr. Chandan said. “These can be broadly put into three categories: adoption of poor lifestyle behaviors due to difficult circumstances (physical inactivity, poor diet, disrupted sleep, substance misuse and smoking); associated development of mental ill health; and the alteration of the immune, metabolic, neuroendocrine, and autonomic nervous system due to the impact of stress on the body.”

It’s not clear why the risk of hypertension may be an outlier among cardiovascular outcomes, Dr. Chandan said. However, he pointed to a similar study whose results hinted that survivors of emotional abuse may be more susceptible to a negative impact on hypertension (Ann Epidemiol. 2012 Aug;22[8]:562-7). The new study does not provide information about the type of abuse suffered by subjects.

Adrienne O’Neil, PhD, a family violence practitioner and cardiovascular epidemiologist at Deakin University in Geelong, Australia, said in an interview that the study is “a very useful contribution to the literature.” However, she cautioned that the study might have missed cases of domestic abuse because it relies on reports from primary care practitioners.

As for the findings, she said they’re surprising because of the divergence of major cardiovascular outcomes such as ischemic heart disease and stroke in groups of women with an average age of 37. “These differential health outcomes were observed over a 2-3 period. You probably wouldn’t expect to see a divergence in cardiovascular outcomes for 5-10 years in this age group.”

Dr. O’Neil said that, moving forward, the research can be helpful to understanding the rise of cardiovascular disease in women aged 35-54, especially in the United States. “The way we assess an individual’s risk of having a heart attack in the future is largely guided by evidence based on men. For a long time, this has neglected female-specific risk factors like polycystic ovary syndrome and hypertensive disorders of pregnancy but also conditions and exposures to which young women are especially vulnerable like depression, anxiety and [domestic abuse],” she said.

“This research is important as it gives us clues about who may be at elevated risk to help us guide prevention efforts. Equally, there is some evidence that chest pain presentation may be a useful predictor of domestic abuse victimization so there could be multiple lines of further inquiry.”

Dr. Chandan, the other study authors, and Dr. O’Neil reported no relevant disclosures.

A single negative screening colonoscopy is associated with long-lasting, significant reductions in the incidence of, and mortality from, colorectal cancer (CRC), but only if the colonoscopy is of high quality, a new study concludes.

The population-based study showed a durable reduction in CRC risk over 17.4 years of follow-up.

“Our findings confirm that a 10-year interval between high-quality screening colonoscopies [as is currently recommended] is safe and that there is no benefit from more frequent screening,” lead author Nastazja Pilonis, MD, from the Maria Sklodowska-Curie National Research Institute of Oncology in Warsaw, Poland, told Medscape Medical News.

“Furthermore, our findings suggest that this interval could even be prolonged, provided the baseline colonoscopy is of high quality,” she added.

However, she emphasized that “only high-quality colonoscopy provided a durable reduction in mortality risk,” and noted that “low-quality colonoscopy was associated with a significantly increased risk of CRC death after the first 5 years following the examination.”

The study was published online May 25 in the Annals of Internal Medicine.
 

Polish Colonoscopy Screening Program

The study included 165,887 average-risk patients enrolled in the Polish Colonoscopy Screening Program who had a single negative screening colonoscopy between October 2000 and December 2011.

Negative colonoscopy was defined as an examination where no evidence of any neoplastic lesion was found.

A high-quality screening colonoscopy was defined by three key properties: cecal intubation, adequate bowel preparation, and an endoscopist’s adenoma detection rate (ADR) of 20% or greater calculated on a yearly basis.

A total of 505 different endoscopists performed the colonoscopies over a median follow-up of 10.1 years.

Compared with the general population, among individuals with a negative colonoscopy, the incidence of CRC was 72% lower and CRC mortality was 81% lower over a period of 5.1 to 10 years, Pilonis and colleagues report.

“This was mainly driven by long-lasting reductions in CRC incidence and mortality (by 84% and 90%, respectively) after high-quality screening colonoscopies,” the investigators emphasize.

Beyond 10 years of follow-up, reductions in CRC incidence and mortality were similar to those observed for the earlier period of 5.1 to 10 years but only for participants who had had a high-quality screening colonoscopy, they emphasize.

Subgroup analyses

In addition, subgroup analyses showed that high-quality colonoscopy – although not those of low-quality – effectively reduced the incidence of, and mortality from, CRC in women and in the proximal colon.

As Pilonis pointed out, previous studies have suggested that women may not benefit from screening colonoscopy to the same extent as men. Plus previous research suggests a reduced CRC risk in the proximal colon relative to that in the distal colon.

Overall, standardized incidence ratios (SIRs) and standardized mortality ratios (SMRs) significantly differed between men and women in the current study, but this difference was not observed after high-quality examinations, the investigators report.

“This is an extremely important finding because, for the first time, we showed that when you have high-quality colonoscopy, women benefit from screening colonoscopy as much as men,” Pilonis emphasized.

Similarly, high-quality screening colonoscopy was associated with a 50% reduction in mortality in the proximal colon throughout the 17.4-year follow-up, whereas there was no decrease in mortality from CRC in the proximal colon with low-quality colonoscopies.

As Pilonis noted, lesions in the proximal colon are more subtle and are harder to detect.”It’s also easier to achieve good bowel preparation in the distal colon than in the proximal colon,” she added.

Women are also more prone to develop lesions in the right (proximal) side of the colon and appear to have more pain with colonoscopy than men, all of which could have contributed to previous reports of colonoscopy not being very effective in women or for the detection of lesions in the proximal colon, as Pilonis suggested.

As the authors explain, current guidelines recommend a 10-year screening interval for the average-risk patient when colonoscopy results are negative.

This interval was partially based on the estimated time it was thought to take an adenoma to progress to a carcinoma and partially on the estimated sensitivity of screening colonoscopy.

“We showed that high-quality is a prerequisite for safe intervals between colonoscopies, Pilonis said. “So I would say that if, at a certain age, a patient has a negative colonoscopy of high-quality, a negative colonoscopy is highly predictive of a very low future risk of CRC,” she added.

The study was funded by the Polish Ministry of Health.

Negative colonoscopy was defined as an examination where no evidence of any neoplastic lesion was found.

A high-quality screening colonoscopy was defined by three key properties: cecal intubation, adequate bowel preparation, and an endoscopist’s adenoma detection rate (ADR) of 20% or greater calculated on a yearly basis.

A total of 505 different endoscopists performed the colonoscopies over a median follow-up of 10.1 years.

Compared with the general population, among individuals with a negative colonoscopy, the incidence of CRC was 72% lower and CRC mortality was 81% lower over a period of 5.1 to 10 years, Pilonis and colleagues report.

“This was mainly driven by long-lasting reductions in CRC incidence and mortality (by 84% and 90%, respectively) after high-quality screening colonoscopies,” the investigators emphasize.

Beyond 10 years of follow-up, reductions in CRC incidence and mortality were similar to those observed for the earlier period of 5.1 to 10 years but only for participants who had had a high-quality screening colonoscopy, they emphasize.

Subgroup analyses

In addition, subgroup analyses showed that high-quality colonoscopy – although not those of low-quality – effectively reduced the incidence of, and mortality from, CRC in women and in the proximal colon.

As Pilonis pointed out, previous studies have suggested that women may not benefit from screening colonoscopy to the same extent as men. Plus previous research suggests a reduced CRC risk in the proximal colon relative to that in the distal colon.

Overall, standardized incidence ratios (SIRs) and standardized mortality ratios (SMRs) significantly differed between men and women in the current study, but this difference was not observed after high-quality examinations, the investigators report.

“This is an extremely important finding because, for the first time, we showed that when you have high-quality colonoscopy, women benefit from screening colonoscopy as much as men,” Pilonis emphasized.

Similarly, high-quality screening colonoscopy was associated with a 50% reduction in mortality in the proximal colon throughout the 17.4-year follow-up, whereas there was no decrease in mortality from CRC in the proximal colon with low-quality colonoscopies.

As Pilonis noted, lesions in the proximal colon are more subtle and are harder to detect.”It’s also easier to achieve good bowel preparation in the distal colon than in the proximal colon,” she added.

Women are also more prone to develop lesions in the right (proximal) side of the colon and appear to have more pain with colonoscopy than men, all of which could have contributed to previous reports of colonoscopy not being very effective in women or for the detection of lesions in the proximal colon, as Pilonis suggested.

As the authors explain, current guidelines recommend a 10-year screening interval for the average-risk patient when colonoscopy results are negative.

This interval was partially based on the estimated time it was thought to take an adenoma to progress to a carcinoma and partially on the estimated sensitivity of screening colonoscopy.

“We showed that high-quality is a prerequisite for safe intervals between colonoscopies, Pilonis said. “So I would say that if, at a certain age, a patient has a negative colonoscopy of high-quality, a negative colonoscopy is highly predictive of a very low future risk of CRC,” she added.

The study was funded by the Polish Ministry of Health.

A single negative screening colonoscopy is associated with long-lasting, significant reductions in the incidence of, and mortality from, colorectal cancer (CRC), but only if the colonoscopy is of high quality, a new study concludes.

The population-based study showed a durable reduction in CRC risk over 17.4 years of follow-up.

“Our findings confirm that a 10-year interval between high-quality screening colonoscopies [as is currently recommended] is safe and that there is no benefit from more frequent screening,” lead author Nastazja Pilonis, MD, from the Maria Sklodowska-Curie National Research Institute of Oncology in Warsaw, Poland, told Medscape Medical News.

“Furthermore, our findings suggest that this interval could even be prolonged, provided the baseline colonoscopy is of high quality,” she added.

However, she emphasized that “only high-quality colonoscopy provided a durable reduction in mortality risk,” and noted that “low-quality colonoscopy was associated with a significantly increased risk of CRC death after the first 5 years following the examination.”

The study was published online May 25 in the Annals of Internal Medicine.

When results in a series of robotic-assisted total knee arthroplasties (TKA) were compared with a series of arthroplasties performed manually by the same surgeon, results were comparable even though the robotic procedures included a learning phase. The results of the study were reported in an abstract scheduled for release at the annual meeting of the American Academy of Orthopaedic Surgeons. The meeting was canceled because of COVID-19.

“Robotics appears to level the playing field for those who are less experienced, so that robotic total knee arthroplasty might be particularly well suited to low-volume surgeons,” reported Sridhar R. Rachala, MD, assistant professor of orthopaedic surgery, University of Buffalo (N.Y.).

In this retrospective cohort study, radiographic and clinical outcomes were evaluated in 164 total knee arthroplasties performed manually over an 8-month period and compared with 300 procedures performed robotically by the same experienced surgeon over the subsequent 15-month period.

There were no significant differences between patient groups for mean age or body mass index. Dr. Rachala, who performed both sets of procedures, reported inherent differences in technique. Specifically, the mechanical alignment was planned for a traditional neutral mechanical axis, while the robotic procedures were planned in kinematic alignment.

When evaluated at 1 year, the mean KOOS JR (Knee Injury and Osteoarthritis Outcome for Joint Replacement) scores were not significantly different for the robotic and manually performed procedures (76.0 vs. 73.9; P = .54). There were also no differences in the final extension (P = .64) or flexion (P = .59).

However, the difference in mean length of stay (2.0 vs. 2.4 days; P = .0002) favored the robotic approach, and the higher proportion of patients discharged to home after robotic surgery (73% vs. 66%; P = .11) suggested a favorable trend. Planned and postoperative alignment was within two degrees for both groups and not significantly different.

“The robotic series were at a disadvantage because it included cases that I performed when first switching to this approach,” reported Dr. Rachala in an interview.

Although a growing number of total hip arthroplasties are performed robotically, there have not so far been many comparisons of clinical outcomes among surgeons experienced with both approaches, according to Dr. Rachala. Acknowledging that a single-surgeon experience could be considered a limitation of this series, Dr. Rachala also considers it a potential strength. Dr. Rachala was highly experienced with manually instrumented total knee arthroplasty when he switched.

“Positioning and alignment are not just more accurate but easier to perform with robotic assistance,” he said, explaining why this approach is likely to offer a particular advantage to surgeons who perform these types of arthroplasties at low volume. He noted that robotic programming helps prevent errors and adopt alternative more personalized alignments.

Although Dr. Rachala acknowledged that long-term and controlled studies are needed, his experience suggests that robotic-assisted procedures are emerging as a viable alternative with advantages for the surgeon as well as the patient.

The principle that robotic assistance can add consistency to total joint arthroplasty is valid, according to Gwo-Chin Lee, MD, an associate professor of orthopaedic surgery, University of Pennsylvania, Philadelphia. “Robotic-assisted arthroplasty improves the accuracy and consistency of the procedure, which can potentially reduce the likelihood of failure. In knees, it is proven to be valuable in unicompartmental replacements in which results are correlated to a surgeon’s surgical volume. It has an equalizing effect relative to a surgeon with more extensive experience,” Dr. Lee said.

The senior author of a recent systematic review and meta-analysis of robotic-assisted unicompartmental knee arthroplasty (J Knee Surg. 2020 Jan 30; doi: 10.1055/s-0040-1701455), Dr. Lee said, “While the impact of robotics on other metrics including patient satisfaction and early recovery continues to be debated among surgeons who specialize in total knee arthroplasties, the technology can aid surgeons in component position, sizing, and ligament balance, particularly for the lower-volume surgeons and ultimately lead to more predictable outcomes.”

Movement-based yoga appears to ease depressive symptoms in a wide range of mental health disorders, a new systematic review and meta-analysis suggest.

Results of the research, which included 19 studies and more than 1,000 patients with a variety of mental health diagnoses, showed that those who practiced yoga experienced greater reductions in depressive symptoms versus those undergoing no treatment, usual treatment, or attention-control exercises. In addition, there was a dose-dependent effect such that more weekly yoga sessions were associated with the greatest reduction in depressive symptoms.

“Once we reviewed all the existing science about the mental health benefits of movement-based yoga, we found that movement-based yoga – which is the same thing as postural yoga or asana – helped reduce symptoms of depression,” study investigator Jacinta Brinsley, BClinExPhys, of the University of South Australia, Adelaide, said in an interview.

“We also found those who practiced more frequently had bigger reductions. However, it didn’t matter how long the individual sessions were; what mattered was how many times per week people practiced,” she added.

The researchers noted that the study is the first to focus specifically on movement-based yoga.

“We excluded meditative forms of yoga, which have often been included in previous reviews, yielding mixed findings. The other thing we’ve done a bit differently is pool all the different diagnoses together and then look at depressive symptoms across them,” said Ms. Brinsley.

The study was published online May 18 in the British Journal of Sports Medicine.
 

Getting clarity

Depressive disorders are currently the world’s leading cause of disability, affecting more than 340 million people.

Most individuals who suffer from depressive disorders also experience a host of physical comorbidities including obesity, type 2 diabetes, metabolic syndrome, and cardiovascular disease.

Perhaps not surprisingly, physical inactivity is also associated with higher levels of depressive symptoms, which may be the reason some international organizations now recommend that physical activity be included as part of routine psychiatric care.

One potential form of exercise is yoga, which has become popular in Western culture, including among psychiatric patients. Although previous systematic reviews and meta-analyses have examined the effects of various yoga interventions on mental health, none has investigated the benefits of yoga across a range of psychiatric diagnoses.

What’s more, the authors of these reviews all urge caution when interpreting their results because of potential heterogeneity of the various yoga interventions, as well as poor methodological reporting.

“As an exercise physiologist, I prescribe evidence-based treatment,” said Ms. Brinsley. “I was interested in seeing if there’s evidence to support movement-based yoga in people who were struggling with mental health or who had a diagnosed mental illness.

“The [previous] findings are quite contradictory and there’s not a clear outcome in terms of intervention results, so we pooled the data and ran the meta-analysis, thinking it would be a great way to add some important evidence to the science,” she added.

To allow for a more comprehensive assessment of yoga’s potential mental health benefits, the investigators included a range of mental health diagnoses.

Dose-dependent effect

Studies were only included in the analysis if they were randomized, controlled trials with a yoga intervention that had a minimum of 50% physical activity during each session in adults with a recognized diagnosed mental disorder. Control conditions were defined as treatment as usual, wait list, or attention controls.

Two investigators independently scanned article titles and abstracts, and a final list of articles for the study was decided by consensus. Study quality was reported using the PEDro checklist; a random-effects meta-analysis was conducted using Comprehensive Meta-Analysis software.

A total of 3,880 records were identified and screened. The investigators assessed full-text versions of 80 articles, 19 of which (1,080 patients) were eligible for inclusion in the review.

Of these, nine studies included patients with a depressive disorder; five trials were in patients with a diagnosis of schizophrenia, three studies included patients with a diagnosis of PTSD, one study included patients diagnosed with alcohol dependence, and one study included patients with a range of psychiatric disorders.

Of the 1,080 patients included in the review, 578 were assigned to yoga and 502 to control conditions. Yoga practice involved a mixture of movement, breathing exercises, and/or mindfulness, but the movement component took up more than half of each session.

The yoga interventions lasted an average of 2.4 months (range, 1.5-2.5 months), with an average of 1.6 sessions per week (range, 1-3 sessions) that lasted an average of 60 minutes (range, 20-90 minutes).

Of the 19 studies (632 patients), 13 reported changes in depressive symptoms and were therefore included in the meta-analysis. The six studies excluded from the quantitative analysis did not report depression symptom scores.

With respect to primary outcomes, individuals who performed yoga showed a greater reduction in depressive symptoms, compared with the three control groups (standardized mean difference, –0.41; 95% CI, –0.65 to –0.17; P < .001).

Specific subgroup analyses showed a moderate effect of yoga on depressive symptoms, compared with wait-list controls (SMD, –0.58; P < .05), treatment as usual (SMD, –0.39; P = .31), and attention controls (SMD, –0.21; P = .22).

Subgroup analyses were also performed with respect to diagnostic category. These data showed a moderate effect of yoga on depressive symptoms in depressive disorders (SMD, –0.40; P < .01), no effect in PTSD (SMD, –0.01; P = .95), a nominal effect in alcohol use disorders (SMD, –0.24; P = .69), and a marked effect in schizophrenia (SMD, –0.90; P < .01).

Movement may be key

Researchers also performed a series of meta-regression analyses, which showed that the number of yoga sessions performed each week had a significant effect on depressive symptoms. Indeed, individuals with higher session frequencies demonstrated a greater improvement in symptoms (beta, –0.44; P < .001).

These findings, said Ms. Brinsley, suggest yoga may be a viable intervention for managing depressive symptoms in patients with a variety of mental disorders.

Based on these findings, Ms. Brinsley said she would encourage mental health practitioners to consider yoga as an evidence-based exercise modality for their patients, along with other conventional forms of exercise.

Equally important was the finding that the number of weekly yoga sessions moderated the effect of depressive symptoms, as it may inform the future design of yoga interventions in patients with mental disorders.

With this in mind, the researchers recommended that such interventions should aim to increase the frequency or weekly sessions rather than the duration of each individual session or the overall duration of the intervention.

However, said Ms. Brinsley, these findings suggest it is the physical aspect of the yoga practice that may be key.

“Yoga comprises several different components, including the movement postures, the breathing component, and the mindfulness or meditative component, but in this meta-analysis we looked specifically at yoga that was at least 50% movement based. So it might have also included mindfulness and breathing, but it had to have the movement,” she said.

Don’t discount meditation

Commenting on the findings, Holger Cramer, MSc, PhD, DSc, who was not involved in the study, noted that the systematic review and meta-analysis builds on a number of previous reviews regarding the benefits of yoga for mental disorders.

“Surprisingly, the largest effect in this analysis was found in schizophrenia, even higher than in patients with depressive disorders,” said Dr. Cramer of the University of Duisburg-Essen (Germany). “This is in strong contradiction to what would otherwise be expected. As the authors point out, only about a quarter of all schizophrenia patients suffer from depression, so there should not be so much room for improvement.”

Dr. Cramer also advised against reducing yoga to simply a physical undertaking. “We have shown in our meta-analysis that those interventions focusing on meditation and/or breathing techniques are the most effective ones,” he added.

As such, he urged that breathing techniques be a part of yoga for treating depression in psychiatric disorders, though care should be taken in patients with PTSD, “since breath control might be perceived as unpleasant.”

For Ms. Brinsley, the findings help solidify yoga’s potential as a genuine treatment option for a variety of mental health patients suffering depressive symptoms.

“It’s about acknowledging that yoga can be a helpful part of treatment and can have a significant effect on mental health,” she noted.

At the same time, practitioners also need to acknowledge that patients suffering from mental health disorders may struggle with motivation when it comes to activities such as yoga.

“Engaging in a new activity can be particularly challenging if you’re struggling with mental health. Nevertheless, it’s important for people to have a choice and do something they enjoy. And yoga can be another tool in their toolbox for managing their mental health,” she said.

The study was funded by the U.K. National Institute for Health Research and Health Education England. Ms. Brinsley and Dr. Cramer have reported no relevant financial relationships.

These data showed a moderate effect of yoga on depressive symptoms in depressive disorders (SMD, –0.40; P < .01), no effect in PTSD (SMD, –0.01; P = .95), a nominal effect in alcohol use disorders (SMD, –0.24; P = .69), and a marked effect in schizophrenia (SMD, –0.90; P < .01).

Movement may be key

Researchers also performed a series of meta-regression analyses, which showed that the number of yoga sessions performed each week had a significant effect on depressive symptoms. Indeed, individuals with higher session frequencies demonstrated a greater improvement in symptoms (beta, –0.44; P < .001).

These findings, said Ms. Brinsley, suggest yoga may be a viable intervention for managing depressive symptoms in patients with a variety of mental disorders.

Based on these findings, Ms. Brinsley said she would encourage mental health practitioners to consider yoga as an evidence-based exercise modality for their patients, along with other conventional forms of exercise.

Equally important was the finding that the number of weekly yoga sessions moderated the effect of depressive symptoms, as it may inform the future design of yoga interventions in patients with mental disorders.

With this in mind, the researchers recommended that such interventions should aim to increase the frequency or weekly sessions rather than the duration of each individual session or the overall duration of the intervention.

However, said Ms. Brinsley, these findings suggest it is the physical aspect of the yoga practice that may be key.

“Yoga comprises several different components, including the movement postures, the breathing component, and the mindfulness or meditative component, but in this meta-analysis we looked specifically at yoga that was at least 50% movement based. So it might have also included mindfulness and breathing, but it had to have the movement,” she said.

Don’t discount meditation

Commenting on the findings, Holger Cramer, MSc, PhD, DSc, who was not involved in the study, noted that the systematic review and meta-analysis builds on a number of previous reviews regarding the benefits of yoga for mental disorders.

“Surprisingly, the largest effect in this analysis was found in schizophrenia, even higher than in patients with depressive disorders,” said Dr. Cramer of the University of Duisburg-Essen (Germany). “This is in strong contradiction to what would otherwise be expected. As the authors point out, only about a quarter of all schizophrenia patients suffer from depression, so there should not be so much room for improvement.”

Dr. Cramer also advised against reducing yoga to simply a physical undertaking. “We have shown in our meta-analysis that those interventions focusing on meditation and/or breathing techniques are the most effective ones,” he added.

As such, he urged that breathing techniques be a part of yoga for treating depression in psychiatric disorders, though care should be taken in patients with PTSD, “since breath control might be perceived as unpleasant.”

For Ms. Brinsley, the findings help solidify yoga’s potential as a genuine treatment option for a variety of mental health patients suffering depressive symptoms.

“It’s about acknowledging that yoga can be a helpful part of treatment and can have a significant effect on mental health,” she noted.

At the same time, practitioners also need to acknowledge that patients suffering from mental health disorders may struggle with motivation when it comes to activities such as yoga.

“Engaging in a new activity can be particularly challenging if you’re struggling with mental health. Nevertheless, it’s important for people to have a choice and do something they enjoy. And yoga can be another tool in their toolbox for managing their mental health,” she said.

The study was funded by the U.K. National Institute for Health Research and Health Education England. Ms. Brinsley and Dr. Cramer have reported no relevant financial relationships.

Movement-based yoga appears to ease depressive symptoms in a wide range of mental health disorders, a new systematic review and meta-analysis suggest.

Results of the research, which included 19 studies and more than 1,000 patients with a variety of mental health diagnoses, showed that those who practiced yoga experienced greater reductions in depressive symptoms versus those undergoing no treatment, usual treatment, or attention-control exercises. In addition, there was a dose-dependent effect such that more weekly yoga sessions were associated with the greatest reduction in depressive symptoms.

“Once we reviewed all the existing science about the mental health benefits of movement-based yoga, we found that movement-based yoga – which is the same thing as postural yoga or asana – helped reduce symptoms of depression,” study investigator Jacinta Brinsley, BClinExPhys, of the University of South Australia, Adelaide, said in an interview.

“We also found those who practiced more frequently had bigger reductions. However, it didn’t matter how long the individual sessions were; what mattered was how many times per week people practiced,” she added.

The researchers noted that the study is the first to focus specifically on movement-based yoga.

“We excluded meditative forms of yoga, which have often been included in previous reviews, yielding mixed findings. The other thing we’ve done a bit differently is pool all the different diagnoses together and then look at depressive symptoms across them,” said Ms. Brinsley.

The study was published online May 18 in the British Journal of Sports Medicine.
 

Getting clarity

Depressive disorders are currently the world’s leading cause of disability, affecting more than 340 million people.

Most individuals who suffer from depressive disorders also experience a host of physical comorbidities including obesity, type 2 diabetes, metabolic syndrome, and cardiovascular disease.

Perhaps not surprisingly, physical inactivity is also associated with higher levels of depressive symptoms, which may be the reason some international organizations now recommend that physical activity be included as part of routine psychiatric care.

One potential form of exercise is yoga, which has become popular in Western culture, including among psychiatric patients. Although previous systematic reviews and meta-analyses have examined the effects of various yoga interventions on mental health, none has investigated the benefits of yoga across a range of psychiatric diagnoses.

What’s more, the authors of these reviews all urge caution when interpreting their results because of potential heterogeneity of the various yoga interventions, as well as poor methodological reporting.

“As an exercise physiologist, I prescribe evidence-based treatment,” said Ms. Brinsley. “I was interested in seeing if there’s evidence to support movement-based yoga in people who were struggling with mental health or who had a diagnosed mental illness.

“The [previous] findings are quite contradictory and there’s not a clear outcome in terms of intervention results, so we pooled the data and ran the meta-analysis, thinking it would be a great way to add some important evidence to the science,” she added.

To allow for a more comprehensive assessment of yoga’s potential mental health benefits, the investigators included a range of mental health diagnoses.

Dose-dependent effect

Studies were only included in the analysis if they were randomized, controlled trials with a yoga intervention that had a minimum of 50% physical activity during each session in adults with a recognized diagnosed mental disorder. Control conditions were defined as treatment as usual, wait list, or attention controls.

Two investigators independently scanned article titles and abstracts, and a final list of articles for the study was decided by consensus. Study quality was reported using the PEDro checklist; a random-effects meta-analysis was conducted using Comprehensive Meta-Analysis software.

A total of 3,880 records were identified and screened. The investigators assessed full-text versions of 80 articles, 19 of which (1,080 patients) were eligible for inclusion in the review.

Of these, nine studies included patients with a depressive disorder; five trials were in patients with a diagnosis of schizophrenia, three studies included patients with a diagnosis of PTSD, one study included patients diagnosed with alcohol dependence, and one study included patients with a range of psychiatric disorders.

Of the 1,080 patients included in the review, 578 were assigned to yoga and 502 to control conditions. Yoga practice involved a mixture of movement, breathing exercises, and/or mindfulness, but the movement component took up more than half of each session.

The yoga interventions lasted an average of 2.4 months (range, 1.5-2.5 months), with an average of 1.6 sessions per week (range, 1-3 sessions) that lasted an average of 60 minutes (range, 20-90 minutes).

Of the 19 studies (632 patients), 13 reported changes in depressive symptoms and were therefore included in the meta-analysis. The six studies excluded from the quantitative analysis did not report depression symptom scores.

With respect to primary outcomes, individuals who performed yoga showed a greater reduction in depressive symptoms, compared with the three control groups (standardized mean difference, –0.41; 95% CI, –0.65 to –0.17; P < .001).

Specific subgroup analyses showed a moderate effect of yoga on depressive symptoms, compared with wait-list controls (SMD, –0.58; P < .05), treatment as usual (SMD, –0.39; P = .31), and attention controls (SMD, –0.21; P = .22).

Subgroup analyses were also performed with respect to diagnostic category. These data showed a moderate effect of yoga on depressive symptoms in depressive disorders (SMD, –0.40; P < .01), no effect in PTSD (SMD, –0.01; P = .95), a nominal effect in alcohol use disorders (SMD, –0.24; P = .69), and a marked effect in schizophrenia (SMD, –0.90; P < .01).

One of the greatest tragedies of the first wave of the COVID-19 pandemic has been the failure of health policy makers to anticipate and mitigate the enormous havoc the policy of social distancing would wreak on mental health and cognitive function in older persons, speakers agreed at a webinar on COVID-19, social distancing, and its impact on social and mental health in the elderly hosted by the International Psychogeriatric Association in collaboration with INTERDEM.

“Social distancing” is a two-edged sword: It is for now and the foreseeable future the only available effective strategy for protecting against infection in the older population most vulnerable to severe forms of COVID-19. Yet social distancing also has caused many elderly – particularly those in nursing homes and other long-term care facilities – to plunge into a profound experience of loneliness, isolation, distress, feelings of abandonment, anxiety, depression, and accelerated cognitive deterioration. And this needn’t have happened, the mental health professionals asserted.

“When are we going to get rid of the term ‘social distancing?’ ” asked IPA President William E. Reichman, MD. “Many have appreciated – including the World Health Organization – that the real issue is physical distancing to prevent contagion. And physical distancing doesn’t have to mean social distancing.”

Social connectedness between elderly persons and their peers and family members can be maintained and should be emphatically encouraged during the physical distancing required by the pandemic, said Myrra Vernooij-Dassen, PhD, of Radboud University in Nigmegen, the Netherlands, and chair of INTERDEM, a pan-European network of dementia researchers.

This can be achieved using readily available technologies, including the telephone and videoconferencing, as well as by creating opportunities for supervised masked visits between a family member and an elderly loved one in outdoor courtyards or gardens within long-term care facilities. And yet, as the pandemic seized hold in many parts of the world, family members were blocked from entry to these facilities, she observed.
 

Impact on mental health, cognition

Dr. Vernooij-Dassen noted that studies of previous quarantine periods as well as preliminary findings during the COVID-19 pandemic demonstrate an inverse relationship between social isolation measures and cognitive functioning in the elderly.

“A striking finding is that lack of social interaction is associated with incident dementia. Conversely, epidemiologic data indicate that a socially integrated lifestyle had a favorable influence on cognitive functioning and could even delay onset of dementia,” she said.

INTERDEM is backing two ongoing studies evaluating the hypothesis that interventions fostering increased social interaction among elderly individuals can delay onset of dementia or favorably affect its course. The proposed mechanism of benefit is stimulation of brain plasticity to enhance cognitive reserve.

“This is a hypothesis of hope. We know that social interaction for humans is like water to plants – we really, really need it,” she explained.

Diego de Leo, MD, PhD, emeritus professor of psychiatry and former director of the Australian Institute for Suicide Research and Prevention at Griffith University in Brisbane, was living in hard-hit Padua, Italy, during the first surge of COVID-19. He described his anecdotal experience.

“What I hear from many Italian colleagues and friends and directors of mental health services is that emergency admissions related to mental disorders declined during the first wave of the COVID pandemic. For example, not many people attended emergency departments due to suicide attempts; there was a very marked decrease in the number of suicide attempts during the worst days of the pandemic,” he said.

People with psychiatric conditions were afraid to go to the hospital because they thought they would contract the infection and die there. That’s changing now, however.

“Now there is an increased number of admissions to mental health units. A new wave. It has been a U-shaped curve. And we’re now witnessing an increasing number of fatal suicides due to persistent fears, due to people imagining that there is no more room for them, and no more future for them from a financial point of view – which is the major negative outcome of this crisis. It will be a disaster for many families,” the psychiatrist continued.

A noteworthy phenomenon in northern Italy was that, when tablets were made available to nursing home residents in an effort to enhance their connectedness to the outside world, those with dementia often became so frustrated and confused by their difficulty in using the devices that they developed a hypokinetic delirium marked by refusal to eat or leave their bed, he reported.

It’s far too early to have reliable data on suicide trends in response to the pandemic, according to Dr. de Leo. But one thing is for sure: The strategy of social distancing employed to curb COVID-19 has increased the prevalence of known risk factors for suicide in older individuals, including loneliness, anxiety, and depression; increased alcohol use; and a perception of being a burden on society. Dr. de Leo directs a foundation dedicated to helping people experiencing traumatic bereavement, and in one recent week, the foundation was contacted by eight families in the province of Padua with a recent death by suicide apparently related to fallout from the COVID-19 pandemic. That’s an unusually high spike in suicide in a province with a population of 1 million.

“People probably preferred to end the agitation, the fear, the extreme anxiety about their destiny by deciding to prematurely truncate their life. That has been reported by nursing staff,” he said.

The Italian government has determined that, to date, 36% of all COVID-related deaths have occurred in people aged 85 years or older, and 84% of deaths were in individuals aged at least 70 years. And in Milan and the surrounding province of Lombardy, it’s estimated that COVID-19 has taken the lives of 25% of all nursing home residents. The North American experience has been uncomfortably similar.

“Almost 80% of COVID deaths in Canada have occurred in congregate settings,” observed Dr. Reichman, professor of psychiatry at the University of Toronto, and president and CEO of Baycrest Health Sciences, a geriatric research center.

“Certainly, the appalling number of deaths in nursing homes is the No. 1 horror of the pandemic,” declared Carmelle Peisah, MBBS, MD, a psychiatrist at the University of New South Wales in Kensington, Australia.
 

The fire next time

The conventional wisdom holds that COVID-19 has caused all sorts of mayhem in the delivery of elder care. Not so, in Dr. Reichman’s view.

“I would suggest that the pandemic has not caused many of the problems we talk about, it’s actually revealed problems that have always been there under the surface. For example, many older people, even before COVID-19, were socially isolated, socially distant. They had difficulty connecting with their relatives, difficulty accessing transportation to get to the store to buy food and see their doctors, and to interact with other older people,” the psychiatrist said.

“I would say as well that the pandemic didn’t cause the problems we’ve seen in long-term congregate senior care. The pandemic revealed them. We’ve had facilities where older people were severely crowded together, which compromises their quality of life, even when there’s not a pandemic. We’ve had difficulty staffing these kinds of environments with people that are paid an honest wage for the very hard work that they do. In many of these settings they’re inadequately trained, not only in infection prevention and control but in all other aspects of care. And the pandemic has revealed that many of these organizations are not properly funded. The government doesn’t support them well enough across jurisdictions, and they can’t raise enough philanthropic funds to provide the kind of quality of life that residents demand,” Dr. Reichman continued.

Could the pandemic spur improved elder care? His hope is that health care professionals, politicians, and society at large will learn from the devastation left by the first surge of the pandemic and will lobby for the resources necessary for much-needed improvements in geriatric care.

“We need to be better prepared should there be not only a second wave of this pandemic, but for other pandemics to come,” Dr. Reichman concluded.

The speakers indicated they had no financial conflicts regarding their presentations.
