Similar brain atrophy in obesity and Alzheimer’s disease
Comparisons of MRI scans for more than 1,000 participants indicate correlations between the two conditions, especially in areas of gray matter thinning, suggesting that managing excess weight might slow cognitive decline and lower the risk for AD, according to the researchers.
However, brain maps of obesity did not correlate with maps of amyloid or tau protein accumulation.
“The fact that obesity-related brain atrophy did not correlate with the distribution of amyloid and tau proteins in AD was not what we expected,” study author Filip Morys, PhD, a postdoctoral researcher at McGill University, Montreal, said in an interview. “But it might just show that the specific mechanisms underpinning obesity- and Alzheimer’s disease–related neurodegeneration are different. This remains to be confirmed.”
The study was published in the Journal of Alzheimer’s Disease.
Cortical Thinning
The current study was prompted by the team’s earlier study, which showed that obesity-related neurodegeneration patterns were visually similar to those of AD, said Dr. Morys. “It was known previously that obesity is a risk factor for AD, but we wanted to directly compare brain atrophy patterns in both, which is what we did in this new study.”
The researchers analyzed data from a pooled sample of more than 1,300 participants. From the ADNI database, the researchers selected participants with AD and age- and sex-matched cognitively healthy controls. From the UK Biobank, the researchers drew a sample of lean, overweight, and obese participants without neurologic disease.
To determine how the weight status of patients with AD affects the correspondence between AD and obesity maps, they categorized participants with AD and healthy controls from the ADNI database into lean, overweight, and obese subgroups.
Then, to investigate mechanisms that might drive the similarities between obesity-related brain atrophy and AD-related amyloid-beta accumulation, they looked for overlapping areas in PET brain maps between patients with these outcomes.
The investigations showed that obesity maps were highly correlated with AD maps, but not with amyloid-beta or tau protein maps. The researchers also found significant correlations between obesity and the lean individuals with AD.
Brain regions with the highest similarities between obesity and AD were located mainly in the left temporal and bilateral prefrontal cortices.
“Our research confirms that obesity-related gray matter atrophy resembles that of AD,” the authors concluded. “Excess weight management could lead to improved health outcomes, slow down cognitive decline in aging, and lower the risk for AD.”
Upcoming research “will focus on investigating how weight loss can affect the risk for AD, other dementias, and cognitive decline in general,” said Dr. Morys. “At this point, our study suggests that obesity prevention, weight loss, but also decreasing other metabolic risk factors related to obesity, such as type-2 diabetes or hypertension, might reduce the risk for AD and have beneficial effects on cognition.”
Lifestyle habits
Commenting on the findings, Claire Sexton, DPhil, vice president of scientific programs and outreach at the Alzheimer’s Association, cautioned that a single cross-sectional study isn’t conclusive. “Previous studies have illustrated that the relationship between obesity and dementia is complex. Growing evidence indicates that people can reduce their risk of cognitive decline by adopting key lifestyle habits, like regular exercise, a heart-healthy diet and staying socially and cognitively engaged.”
The Alzheimer’s Association is leading a 2-year clinical trial, U.S. Pointer, to study how targeting these risk factors in combination may reduce risk for cognitive decline in older adults.
The work was supported by a Foundation Scheme award from the Canadian Institutes of Health Research. Dr. Morys received a postdoctoral fellowship from Fonds de Recherche du Quebec – Santé. Data collection and sharing were funded by the Alzheimer’s Disease Neuroimaging Initiative, the National Institute on Aging, the National Institute of Biomedical Imaging and Bioengineering, and multiple pharmaceutical companies and other private sector organizations. Dr. Morys and Dr. Sexton reported no relevant financial relationships.

FROM THE JOURNAL OF ALZHEIMER’S DISEASE
Psychiatric illnesses share common brain network
Investigators used coordinate and lesion network mapping to assess whether there was a shared brain network common to multiple psychiatric disorders. In a meta-analysis of almost 200 studies encompassing more than 15,000 individuals, they found that atrophy coordinates across these six psychiatric conditions all mapped to a common brain network.
Moreover, lesion damage to this network in patients with penetrating head trauma correlated with the number of psychiatric illnesses that the patients were diagnosed with post trauma.
The findings have “bigger-picture potential implications,” lead author Joseph Taylor, MD, PhD, medical director of transcranial magnetic stimulation at Brigham and Women’s Hospital’s Center for Brain Circuit Therapeutics, Boston, told this news organization.
“In psychiatry, we talk about symptoms and define our disorders based on symptom checklists, which are fairly reliable but don’t have neurobiological underpinnings,” said Dr. Taylor, who is also an associate psychiatrist in Brigham’s department of psychiatry.
By contrast, “in neurology, we ask: ‘Where is the lesion?’ Studying brain networks could potentially help us diagnose and treat people with psychiatric illness more effectively, just as we treat neurological disorders,” he added.
The findings were published online in Nature Human Behavior.
Beyond symptom checklists
Dr. Taylor noted that, in the field of psychiatry, “we often study disorders in isolation,” such as generalized anxiety disorder and major depressive disorder.
“But what see clinically is that half of patients meet the criteria for more than one psychiatric disorder,” he said. “It can be difficult to diagnose and treat these patients, and there are worse treatment outcomes.”
There is also a “discrepancy” between how these disorders are studied (one at a time) and how patients are treated in clinic, Dr. Taylor noted. And there is increasing evidence that psychiatric disorders may share a common neurobiology.
This “highlights the possibility of potentially developing transdiagnostic treatments based on common neurobiology, not just symptom checklists,” Dr. Taylor said.
Prior work “has attempted to map abnormalities to common brain regions rather than to a common brain network,” the investigators wrote. Moreover, “prior studies have rarely tested specificity by comparing psychiatric disorders to other brain disorders.”
In the current study, the researchers used “morphometric brain lesion datasets coupled with a wiring diagram of the human brain to derive a convergent brain network for psychiatric illness.”
They analyzed four large published datasets. Dataset 1 was sourced from an activation likelihood estimation meta-analysis (ALE) of whole-brain voxel-based studies that compared patients with psychiatric disorders such as schizophrenia, BD, depression, addiction, OCD, and anxiety to healthy controls (n = 193 studies; 15,892 individuals in total).
Dataset 2 was drawn from published neuroimaging studies involving patients with Alzheimer’s disease (AD) and other neurodegenerative conditions (n = 72 studies). They reported coordinates regarding which patients with these disorders had more atrophy compared with control persons.
Dataset 3 was sourced from the Vietnam Head Injury study, which followed veterans with and those without penetrating head injuries (n = 194 veterans with injuries). Dataset 4 was sourced from published neurosurgical ablation coordinates for depression.
Shared neurobiology
Upon analyzing dataset 1, the researchers found decreased gray matter in the bilateral anterior insula, dorsal anterior cingulate cortex, dorsomedial prefrontal cortex, thalamus, amygdala, hippocampus, and parietal operculum – findings that are “consistent with prior work.”
However, fewer than 35% of the studies contributed to any single cluster; and no cluster was specific to psychiatric versus neurodegenerative coordinates (drawn from dataset 2).
On the other hand, coordinate network mapping yielded “more statistically robust” (P < .001) results, which were found in 85% of the studies. “Psychiatric atrophy coordinates were functionally connected to the same network of brain regions,” the researchers reported.
This network was defined by two types of connectivity, positive and negative.
“The topography of this transdiagnostic network was independent of the statistical threshold and specific to psychiatric (vs. neurodegenerative) disorders, with the strongest peak occurring in the posterior parietal cortex (Brodmann Area 7) near the intraparietal sulcus,” the investigators wrote.
When lesions from dataset 3 were overlaid onto the ALE map and the transdiagnostic network in order to evaluate whether damage to either map correlated with number of post-lesion psychiatric diagnosis, results showed no evidence of a correlation between psychiatric comorbidity and damage on the ALE map (Pearson r, 0.02; P = .766).
However, when the same approach was applied to the transdiagnostic network, a statistically significant correlation was found between psychiatric comorbidity and lesion damage (Pearson r, –0.21; P = .01). A multiple regression model showed that the transdiagnostic, but not the ALE, network “independently predicted the number of post-lesion psychiatric diagnoses” (P = .003 vs. P = .1), the investigators reported.
All four neurosurgical ablative targets for psychiatric disorders found on analysis of dataset 4 “intersected” and aligned with the transdiagnostic network.
“The study does not immediately impact clinical practice, but it would be helpful for practicing clinicians to know that psychiatric disorders commonly co-occur and might share common neurobiology and a convergent brain network,” Dr. Taylor said.
“Future work based on our findings could potentially influence clinical trials and clinical practice, especially in the area of brain stimulation,” he added.
‘Exciting new targets’
In a comment, Desmond Oathes, PhD, associate director, Center for Neuromodulation and Stress, University of Pennsylvania, Philadelphia, said the “next step in the science is to combine individual brain imaging, aka, ‘individualized connectomes,’ with these promising group maps to determine something meaningful at the individual patient level.”
Dr. Oathes, who is also a faculty clinician at the Center for the Treatment and Study of Anxiety and was not involved with the study, noted that an open question is whether the brain volume abnormalities/atrophy “can be changed with treatment and in what direction.”
A “strong take-home message from this paper is that brain volume measures from single coordinates are noisy as measures of psychiatric abnormality, whereas network effects seem to be especially sensitive for capturing these effects,” Dr. Oathes said.
The “abnormal networks across these disorders do not fit easily into well-known networks from healthy participants. However, they map well onto other databases relevant to psychiatric disorders and offer exciting new potential targets for prospective treatment studies,” he added.
The investigators received no specific funding for this work. Dr. Taylor reported no relevant financial relationships. Dr. Oathes reported no relevant financial relationships.

FROM NATURE HUMAN BEHAVIOR
Can a ‘smart’ skin patch detect early neurodegenerative diseases?
A new “smart patch” composed of microneedles that can detect proinflammatory markers via simulated skin interstitial fluid (ISF) may help diagnose neurodegenerative disorders such as Alzheimer’s disease and Parkinson’s disease very early on.
Originally developed to deliver medications and vaccines via the skin in a minimally invasive manner, the microneedle arrays were fitted with molecular sensors that, when placed on the skin, detect neuroinflammatory biomarkers such as interleukin-6 in as little as 6 minutes.
The literature suggests that these biomarkers of neurodegenerative disease are present years before patients become symptomatic, said study investigator Sanjiv Sharma, PhD.
“Neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease are [characterized by] progressive loss in nerve cell and brain cells, which leads to memory problems and a loss of mental ability. That is why early diagnosis is key to preventing the loss of brain tissue in dementia, which can go undetected for years,” added Dr. Sharma, who is a lecturer in medical engineering at Swansea (Wales) University.
Dr. Sharma developed the patch with scientists at the Polytechnic of Porto (Portugal) School of Engineering in Portugal. In 2022, they designed, and are currently testing, a microneedle patch that will deliver the COVID vaccine.
The investigators describe their research on the patch’s ability to detect IL-6 in an article published in ACS Omega.
At-home diagnosis?
“The skin is the largest organ in the body – it contains more skin interstitial fluid than the total blood volume,” Dr. Sharma noted. “This fluid is an ultrafiltrate of blood and holds biomarkers that complement other biofluids, such as sweat, saliva, and urine. It can be sampled in a minimally invasive manner and used either for point-of-care testing or real-time using microneedle devices.”
Dr. Sharma and associates tested the microneedle patch in artificial ISF that contained the inflammatory cytokine IL-6. They found that the patch accurately detected IL-6 concentrations as low as 1 pg/mL in the fabricated ISF solution.
“In general, the transdermal sensor presented here showed simplicity in designing, short measuring time, high accuracy, and low detection limit. This approach seems a successful tool for the screening of inflammatory biomarkers in point of care testing wherein the skin acts as a window to the body,” the investigators reported.
Dr. Sharma noted that early detection of neurodegenerative diseases is crucial, as once symptoms appear, the disease may have already progressed significantly, and meaningful intervention is challenging.
The device has yet to be tested in humans, which is the next step, said Dr. Sharma.
“We will have to test the hypothesis through extensive preclinical and clinical studies to determine if bloodless, transdermal (skin) diagnostics can offer a cost-effective device that could allow testing in simpler settings such as a clinician’s practice or even home settings,” he noted.
Early days
Commenting on the research, David K. Simon, MD, PhD, professor of neurology at Harvard Medical School, Boston, said it is “a promising step regarding validation of a potentially beneficial method for rapidly and accurately measuring IL-6.”
However, he added, “many additional steps are needed to validate the method in actual human skin and to determine whether or not measuring these biomarkers in skin will be useful in studies of neurodegenerative diseases.”
He noted that one study limitation is that inflammatory cytokines such as IL-6 are highly nonspecific, and levels are elevated in various diseases associated with inflammation.
“It is highly unlikely that measuring IL-6 will be useful as a diagnostic tool. However, it does have potential as a biomarker for measuring the impact of treatments aimed at reducing inflammation. As the authors point out, it’s more likely that clinicians will require a panel of biomarkers rather than only measuring IL-6,” he said.
The study was funded by Fundação para a Ciência e Tecnologia. The investigators disclosed no relevant financial relationships.

Originally developed to deliver medications and vaccines via the skin in a minimally invasive manner, the microneedle arrays were fitted with molecular sensors that, when placed on the skin, detect neuroinflammatory biomarkers such as interleukin-6 in as little as 6 minutes.
The literature suggests that these biomarkers of neurodegenerative disease are present years before patients become symptomatic, said study investigator Sanjiv Sharma, PhD.
“Neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease are [characterized by] progressive loss in nerve cell and brain cells, which leads to memory problems and a loss of mental ability. That is why early diagnosis is key to preventing the loss of brain tissue in dementia, which can go undetected for years,” added Dr. Sharma, who is a lecturer in medical engineering at Swansea (Wales) University.
Dr. Sharma developed the patch with scientists at the Polytechnic of Porto (Portugal) School of Engineering in Portugal. In 2022, they designed, and are currently testing, a microneedle patch that will deliver the COVID vaccine.
The investigators describe their research on the patch’s ability to detect IL-6 in an article published in ACS Omega.
At-home diagnosis?
“The skin is the largest organ in the body – it contains more skin interstitial fluid than the total blood volume,” Dr. Sharma noted. “This fluid is an ultrafiltrate of blood and holds biomarkers that complement other biofluids, such as sweat, saliva, and urine. It can be sampled in a minimally invasive manner and used either for point-of-care testing or real-time using microneedle devices.”
Dr. Sharma and associates tested the microneedle patch in artificial ISF that contained the inflammatory cytokine IL-6. They found that the patch accurately detected IL-6 concentrations as low as 1 pg/mL in the fabricated ISF solution.
“In general, the transdermal sensor presented here showed simplicity in designing, short measuring time, high accuracy, and low detection limit. This approach seems a successful tool for the screening of inflammatory biomarkers in point of care testing wherein the skin acts as a window to the body,” the investigators reported.
Dr. Sharma noted that early detection of neurodegenerative diseases is crucial, as once symptoms appear, the disease may have already progressed significantly, and meaningful intervention is challenging.
The device has yet to be tested in humans, which is the next step, said Dr. Sharma.
“We will have to test the hypothesis through extensive preclinical and clinical studies to determine if bloodless, transdermal (skin) diagnostics can offer a cost-effective device that could allow testing in simpler settings such as a clinician’s practice or even home settings,” he noted.
Early days
Commenting on the research, David K. Simon, MD, PhD, professor of neurology at Harvard Medical School, Boston, said it is “a promising step regarding validation of a potentially beneficial method for rapidly and accurately measuring IL-6.”
However, he added, “many additional steps are needed to validate the method in actual human skin and to determine whether or not measuring these biomarkers in skin will be useful in studies of neurodegenerative diseases.”
He noted that one study limitation is that inflammatory cytokines such as IL-6 are highly nonspecific, and levels are elevated in various diseases associated with inflammation.
“It is highly unlikely that measuring IL-6 will be useful as a diagnostic tool. However, it does have potential as a biomarker for measuring the impact of treatments aimed at reducing inflammation. As the authors point out, it’s more likely that clinicians will require a panel of biomarkers rather than only measuring IL-6,” he said.
The study was funded by Fundação para a Ciência e Tecnologia. The investigators disclosed no relevant financial relationships.

Citing workplace violence, one-fourth of critical care workers are ready to quit
A surgeon in Tulsa shot by a disgruntled patient. A doctor in India beaten by a group of bereaved family members. A general practitioner in the United Kingdom threatened with stabbing. A new study identifies this trend and finds that 25% of health care workers polled were willing to quit because of such violence.
“That was pretty appalling,” Rahul Kashyap, MD, MBA, MBBS, recalls. Dr. Kashyap is one of the leaders of the Violence Study of Healthcare Workers and Systems (ViSHWaS), which polled an international sample of physicians, nurses, and hospital staff. This study has worrying implications, Dr. Kashyap says. In a time when hospital staff are reporting burnout in record numbers, further deterrents may be the last thing our health care system needs. But Dr. Kashyap hopes that bringing awareness to these trends may allow physicians, policymakers, and the public to mobilize and intervene before it’s too late.
Previous studies have revealed similar trends. The rate of workplace violence directed at U.S. health care workers is five times that of workers in any other industry, according to the Bureau of Labor Statistics. The same study found that attacks had increased 63% from 2011 to 2018. Other polls that focus on the pandemic show that nearly half of U.S. nurses believe that violence increased since the world shut down. Well before the pandemic, however, a study from the Indian Medical Association found that 75% of doctors experienced workplace violence.
With this history in mind, perhaps it’s not surprising that the idea for the study came from the authors’ personal experiences. They had seen coworkers go through attacks, or they had endured attacks themselves, Dr. Kashyap says. But they couldn’t find any global data to back up these experiences. So Dr. Kashyap and his colleagues formed a web of volunteers dedicated to creating a cross-sectional study.
They got in touch with researchers from countries across Asia, the Middle East, South America, North America, and Africa. The initial group agreed to reach out to their contacts, casting a wide net. Researchers used WhatsApp, LinkedIn, and text messages to distribute the survey. Health care workers in each country completed the brief questionnaire, recalling their prepandemic world and evaluating their current one.
Within 2 months, they had reached health care workers in more than 100 countries. They concluded the study when they received about 5,000 results, according to Dr. Kashyap, and then began the process of stratifying the data. For this report, they focused on critical care, emergency medicine, and anesthesiology, which resulted in 598 responses from 69 countries. Of these, India and the United States had the highest number of participants.
In all, 73% of participants reported facing physical or verbal violence while in the hospital; 48% said they felt less motivated to work because of that violence; 39% of respondents believed that the amount of violence they experienced was the same as before the COVID-19 pandemic; and 36% of respondents believed that violence had increased. Even though they were trained on guidelines from the Occupational Safety and Health Administration, 20% of participants felt unprepared to face violence.
Although the study didn’t analyze the reasons workers felt this way, Dr. Kashyap speculates that it could be related to the medical distrust that grew during the pandemic or the stress patients and health care professionals experienced during its peak.
Regardless, the researchers say their study is a starting point. Now that the trend has been highlighted, it may be acted on.
Moving forward, Dr. Kashyap believes that controlling for different variables could determine whether factors like gender or shift time put a worker at higher risk for violence. He hopes it’s possible to interrupt these patterns and reestablish trust in the hospital environment. “It’s aspirational, but you’re hoping that through studies like ViSHWaS, which means trust in Hindi ... [we could restore] the trust and confidence among health care providers for the patients and family members.”

Feds charge 25 nursing school execs, staff in fake diploma scheme
The U.S. Department of Justice recently announced charges against 25 owners, operators, and employees of three Florida nursing schools in a fraud scheme in which they sold as many as 7,600 fake nursing degrees.
The purchasers in the diploma scheme paid $10,000 to $15,000 for degrees and transcripts and some 2,800 of the buyers passed the national nursing licensing exam to become registered nurses (RNs) and licensed practice nurses/vocational nurses (LPN/VNs) around the country, according to The New York Times.
Many of the degree recipients went on to work at hospitals, nursing homes, and Veterans Affairs medical centers, according to the U.S. Attorney’s Office for the Southern District of Florida.
Several national nursing organizations cooperated with the investigation, and the Delaware Division of Professional Regulation already annulled 26 licenses, according to the Delaware Nurses Association. Fake licenses were issued in five states, according to federal reports.
“We are deeply unsettled by this egregious act,” DNA President Stephanie McClellan, MSN, RN, CMSRN, said in the group’s press statement. “We want all Delaware nurses to be aware of this active issue and to speak up if there is a concern regarding capacity to practice safely by a colleague/peer,” she said.
The Oregon State Board of Nursing is also investigating at least a dozen nurses who may have paid for their degrees, according to a Portland CBS affiliate.
The National Council of State Boards of Nursing said in a statement that it had helped authorities identify and monitor the individuals who allegedly provided the false degrees.
Nursing community reacts
News of the fraud scheme spread through the nursing community, including social media. “The recent report on falsified nursing school degrees is both heartbreaking and serves as an eye-opener,” tweeted Usha Menon, PhD, RN, FAAN, dean and health professor of the University of South Florida Health College of Nursing. “There was enough of a need that prompted these bad actors to develop a scheme that could’ve endangered dozens of lives.”
Jennifer Mensik Kennedy, PhD, MBA, RN, the new president of the American Nurses Association, also weighed in. “The accusation that personnel at once-accredited nursing schools allegedly participated in this scheme is simply deplorable. These unlawful and unethical acts disparage the reputation of actual nurses everywhere who have rightfully earned [their titles] through their education, hard work, dedication, and time.”
The false degrees and transcripts were issued by three once-accredited and now-shuttered nursing schools in South Florida: Palm Beach School of Nursing, Sacred Heart International Institute, and Sienna College.
The alleged co-conspirators reportedly made $114 million from the scheme, which dates back to 2016, according to several news reports. Each defendant faces up to 20 years in prison.
Most LPN programs charge $10,000 to $15,000 to complete a program, Robert Rosseter, a spokesperson for the American Association of Colleges of Nursing (AACN), told this news organization.
None were AACN members, and none were accredited by the Commission on Collegiate Nursing Education, which is AACN’s autonomous accrediting agency, Mr. Rosseter said. AACN membership is voluntary and is open to schools offering baccalaureate or higher degrees, he explained.
“What is disturbing about this investigation is that there are over 7,600 people around the country with fraudulent nursing credentials who are potentially in critical health care roles treating patients,” Chad Yarbrough, acting special agent in charge for the FBI in Miami, said in the federal justice department release.
‘Operation Nightingale’ based on tip
The federal action, dubbed “Operation Nightingale” after the nursing pioneer Florence Nightingale, began in 2019. It was based on a tip related to a case in Maryland, according to Nurse.org.
That case ensnared Palm Beach School of Nursing owner Johanah Napoleon, who reportedly was selling fake degrees for $6,000 to $18,000 each to two individuals in Maryland and Virginia. Ms. Napoleon was charged in 2021 and eventually pled guilty. The Florida Board of Nursing shut down the Palm Beach school in 2017 owing to its students’ low passing rate on the national licensing exam.
Two participants in the bigger scheme who had also worked with Ms. Napoleon – Geralda Adrien and Woosvelt Predestin – were indicted in 2021. Ms. Adrien owned private education companies for people who at aspired to be nurses, and Mr. Predestin was an employee. They were sentenced to 27 months in prison last year and helped the federal officials build the larger case.
The 25 individuals who were charged Jan. 25 operated in Delaware, New York, New Jersey, Texas, and Florida.
Schemes lured immigrants
In the scheme involving Siena College, some of the individuals acted as recruiters to direct nurses who were looking for employment to the school, where they allegedly would then pay for an RN or LPN/VN degree. The recipients of the false documents then used them to obtain jobs, including at a hospital in Georgia and a Veterans Affairs medical center in Maryland, according to one indictment. The president of Siena and her co-conspirators sold more than 2,000 fake diplomas, according to charging documents.
At the Palm Beach College of Nursing, individuals at various nursing prep and education programs allegedly helped others obtain fake degrees and transcripts, which were then used to pass RN and LPN/VN licensing exams in states that included Massachusetts, New Jersey, New York, and Ohio, according to the indictment.
Some individuals then secured employment with a nursing home in Ohio, a home health agency for pediatric patients in Massachusetts, and skilled nursing facilities in New York and New Jersey.
Prosecutors allege that the president of Sacred Heart International Institute and two other co-conspirators sold 588 fake diplomas.
The FBI said that some of the aspiring nurses who were talked into buying the degrees were LPNs who wanted to become RNs and that most of those lured into the scheme were from South Florida’s Haitian American immigrant community, Nurse.org reported.

Two participants in the bigger scheme who had also worked with Ms. Napoleon – Geralda Adrien and Woosvelt Predestin – were indicted in 2021. Ms. Adrien owned private education companies for people who at aspired to be nurses, and Mr. Predestin was an employee. They were sentenced to 27 months in prison last year and helped the federal officials build the larger case.
The 25 individuals who were charged Jan. 25 operated in Delaware, New York, New Jersey, Texas, and Florida.
Schemes lured immigrants
In the scheme involving Siena College, some of the individuals acted as recruiters to direct nurses who were looking for employment to the school, where they allegedly would then pay for an RN or LPN/VN degree. The recipients of the false documents then used them to obtain jobs, including at a hospital in Georgia and a Veterans Affairs medical center in Maryland, according to one indictment. The president of Siena and her co-conspirators sold more than 2,000 fake diplomas, according to charging documents.
At the Palm Beach College of Nursing, individuals at various nursing prep and education programs allegedly helped others obtain fake degrees and transcripts, which were then used to pass RN and LPN/VN licensing exams in states that included Massachusetts, New Jersey, New York, and Ohio, according to the indictment.
Some individuals then secured employment with a nursing home in Ohio, a home health agency for pediatric patients in Massachusetts, and skilled nursing facilities in New York and New Jersey.
Prosecutors allege that the president of Sacred Heart International Institute and two other co-conspirators sold 588 fake diplomas.
The FBI said that some of the aspiring nurses who were talked into buying the degrees were LPNs who wanted to become RNs and that most of those lured into the scheme were from South Florida’s Haitian American immigrant community, Nurse.org reported.

Biden to end COVID emergencies in May
Doing so will have many effects, including the end of free vaccines and health services to fight the pandemic. The public health emergency has been renewed every 90 days since it was declared by the Trump administration in January 2020.
The declaration allowed major changes throughout the health care system to deal with the pandemic, including the free distribution of vaccines, testing, and treatments. In addition, telehealth services were expanded, and Medicaid and the Children’s Health Insurance Program were extended to millions more Americans.
Biden said the COVID-19 national emergency is set to expire March 1 while the declared public health emergency would currently expire on April 11. The president said both will be extended to end May 11.
There were nearly 300,000 newly reported COVID-19 cases in the United States for the week ending Jan. 25, according to CDC data, as well as more than 3,750 deaths.

Surgeon General says 13-year-olds shouldn’t be on social media
The U.S. Surgeon General says 13 years old is too young to begin using social media.
Most social media platforms including TikTok, Snapchat, Instagram, and Facebook allow users to create accounts if they say they are at least 13 years old.
“I, personally, based on the data I’ve seen, believe that 13 is too early. ... It’s a time where it’s really important for us to be thoughtful about what’s going into how they think about their own self-worth and their relationships, and the skewed and often distorted environment of social media often does a disservice to many of those children,” U.S. Surgeon General Vivek Murthy, MD, told CNN.
Research has shown that teens are susceptible to cyberbullying and serious mental health impacts from social media usage and online activity during an era when the influence of the Internet has become everywhere for young people.
According to the Pew Research Center, 95% of teens age 13 and up have a smartphone, and 97% of teens say they use the Internet daily. Among 13- and 14-year-olds, 61% say they use TikTok and 51% say they use Snapchat. Older teens ages 15-17 use those social media platforms at higher rates, with 71% saying they use TikTok and 65% using Snapchat.
“If parents can band together and say you know, as a group, we’re not going to allow our kids to use social media until 16 or 17 or 18 or whatever age they choose, that’s a much more effective strategy in making sure your kids don’t get exposed to harm early,” Dr. Murthy said.

Six healthy lifestyle habits linked to slowed memory decline
Investigators found that a healthy diet, cognitive activity, regular physical exercise, not smoking, and abstaining from alcohol were significantly linked to slowed cognitive decline irrespective of APOE4 status.
After adjusting for health and socioeconomic factors, investigators found that each individual healthy behavior was associated with a slower-than-average decline in memory over a decade. A healthy diet emerged as the strongest deterrent, followed by cognitive activity and physical exercise.
“A healthy lifestyle is associated with slower memory decline, even in the presence of the APOE4 allele,” study investigators led by Jianping Jia, MD, PhD, of the Innovation Center for Neurological Disorders and the department of neurology, Xuan Wu Hospital, Capital Medical University, Beijing, write.
“This study might offer important information to protect older adults against memory decline,” they add.
The study was published online in the BMJ.
Preventing memory decline
Memory “continuously declines as people age,” but age-related memory decline is not necessarily a prodrome of dementia and can “merely be senescent forgetfulness,” the investigators note. This can be “reversed or [can] become stable,” instead of progressing to a pathologic state.
Factors affecting memory include aging, APOE4 genotype, chronic diseases, and lifestyle patterns, with lifestyle “receiving increasing attention as a modifiable behavior.”
Nevertheless, few studies have focused on the impact of lifestyle on memory, and those that have are mostly cross-sectional and also “did not consider the interaction between a healthy lifestyle and genetic risk,” the researchers note.
To investigate, the researchers conducted a longitudinal study, known as the China Cognition and Aging Study, that considered genetic risk as well as lifestyle factors.
The study began in 2009 and concluded in 2019. Participants were evaluated and underwent neuropsychological testing in 2012, 2014, 2016, and at the study’s conclusion.
Participants (n = 29,072; mean [SD] age, 72.23 [6.61] years; 48.54% women; 20.43% APOE4 carriers) were required to have normal cognitive function at baseline. Data on those whose condition progressed to mild cognitive impairment (MCI) or dementia during the follow-up period were excluded after their diagnosis.
The Mini–Mental State Examination was used to assess global cognitive function. Memory function was assessed using the World Health Organization/University of California, Los Angeles Auditory Verbal Learning Test.
“Lifestyle” consisted of six modifiable factors: physical exercise (weekly frequency and total time), smoking (current, former, or never-smokers), alcohol consumption (never drank, drank occasionally, low to excess drinking, and heavy drinking), diet (daily intake of 12 food items: fruits, vegetables, fish, meat, dairy products, salt, oil, eggs, cereals, legumes, nuts, tea), cognitive activity (writing, reading, playing cards, mahjong, other games), and social contact (participating in meetings, attending parties, visiting friends/relatives, traveling, chatting online).
Participants’ lifestyles were scored on the basis of the number of healthy factors they engaged in.
Participants were also stratified by APOE genotype into APOE4 carriers and noncarriers.
Demographic and other items of health information, including the presence of medical illness, were used as covariates. The researchers also included the “learning effect of each participant as a covariate, due to repeated cognitive assessments.”
Important for public health
During the 10-year period, 7,164 participants died, and 3,567 stopped participating.
Participants in the favorable and average groups showed slower memory decline per increased year of age (0.007 [0.005-0.009], P < .001; and 0.002 [0 .000-0.003], P = .033 points higher, respectively), compared with those in the unfavorable group.
Healthy diet had the strongest protective effect on memory.
Memory decline occurred faster in APOE4 vesus non-APOE4 carriers (0.002 points/year [95% confidence interval, 0.001-0.003]; P = .007).
But APOE4 carriers with favorable and average lifestyles showed slower memory decline (0.027 [0.023-0.031] and 0.014 [0.010-0.019], respectively), compared with those with unfavorable lifestyles. Similar findings were obtained in non-APOE4 carriers.
Those with favorable or average lifestyle were respectively almost 90% and 30% less likely to develop dementia or MCI, compared with those with an unfavorable lifestyle.
The authors acknowledge the study’s limitations, including its observational design and the potential for measurement errors, owing to self-reporting of lifestyle factors. Additionally, some participants did not return for follow-up evaluations, leading to potential selection bias.
Nevertheless, the findings “might offer important information for public health to protect older [people] against memory decline,” they note – especially since the study “provides evidence that these effects also include individuals with the APOE4 allele.”
‘Important, encouraging’ research
In a comment, Severine Sabia, PhD, a senior researcher at the Université Paris Cité, INSERM Institut National de la Santé et de la Recherche Medicalé, France, called the findings “important and encouraging.”
However, said Dr. Sabia, who was not involved with the study, “there remain important research questions that need to be investigated in order to identify key behaviors: which combination, the cutoff of risk, and when to intervene.”
Future research on prevention “should examine a wider range of possible risk factors” and should also “identify specific exposures associated with the greatest risk, while also considering the risk threshold and age at exposure for each one.”
In an accompanying editorial, Dr. Sabia and co-author Archana Singh-Manoux, PhD, note that the risk of cognitive decline and dementia are probably determined by multiple factors.
They liken it to the “multifactorial risk paradigm introduced by the Framingham study,” which has “led to a substantial reduction in cardiovascular disease.” A similar approach could be used with dementia prevention, they suggest.
The authors received support from the Xuanwu Hospital of Capital Medical University for the submitted work. One of the authors received a grant from the French National Research Agency. The other authors have disclosed no relevant financial relationships. Dr. Sabia received grant funding from the French National Research Agency. Dr. Singh-Manoux received grants from the National Institute on Aging of the National Institutes of Health.

Even one head injury boosts all-cause mortality risk
An analysis of more than 13,000 adult participants in the Atherosclerosis Risk in Communities (ARIC) study showed a dose-response pattern in which one head injury was linked to a 66% increased risk for all-cause mortality, and two or more head injuries were associated with twice the risk in comparison with no head injuries.
These findings underscore the importance of preventing head injuries and of swift clinical intervention once a head injury occurs, lead author Holly Elser, MD, PhD, department of neurology, Hospital of the University of Pennsylvania, Philadelphia, told this news organization.
“Clinicians should counsel patients who are at risk for falls about head injuries and ensure patients are promptly evaluated in the hospital setting if they do have a fall – especially with loss of consciousness or other symptoms, such as headache or dizziness,” Dr. Elser added.
The findings were published online in JAMA Neurology.
Consistent evidence
There is “pretty consistent evidence” that mortality rates are increased in the short term after head injury, predominantly among hospitalized patients, Dr. Elser noted.
“But there’s less evidence about the long-term mortality implications of head injuries and less evidence from adults living in the community,” she added.
The analysis included 13,037 participants in the ARIC study, an ongoing study involving adults aged 45-65 years who were recruited from four geographically and racially diverse U.S. communities. The mean age at baseline (1987-1989) was 54 years; 57.7% were women; and 27.9% were Black.
Study participants are followed at routine in-person visits and semiannually via telephone.
Data on head injuries came from hospital diagnostic codes and self-reports. These reports included information on the number of injuries and whether the injury required medical care and involved loss of consciousness.
During the 27-year follow-up, 18.4% of the study sample had at least one head injury. Injuries occurred more frequently among women, which may reflect the predominance of women in the study population, said Dr. Elser.
Overall, about 56% of participants died during the study period. The estimated median amount of survival time after head injury was 4.7 years.
The most common causes of death were neoplasm, cardiovascular disease, and neurologic disorders. Regarding specific neurologic causes of death, the researchers found that 62.2% of deaths were due to neurodegenerative disease among individuals with head injury, vs. 51.4% among those without head injury.
This, said Dr. Elser, raises the possibility of reverse causality. “If you have a neurodegenerative disorder like Alzheimer’s disease dementia or Parkinson’s disease that leads to difficulty walking, you may be more likely to fall and have a head injury. The head injury in turn may lead to increased mortality,” she noted.
However, she stressed that the data on cause-specific mortality are exploratory. “Our research motivates future studies that really examine this time-dependent relationship between neurodegenerative disease and head injuries,” Dr. Elser said.
Dose-dependent response
In the unadjusted analysis, the hazard ratio of mortality among individuals with head injury was 2.21 (95% confidence interval, 2.09-2.34) compared with those who did not have head injury.
The association remained significant with adjustment for sociodemographic factors (HR, 1.99; 95% CI, 1.88-2.11) and with additional adjustment for vascular risk factors (HR, 1.92; 95% CI, 1.81-2.03).
The findings also showed a dose-response pattern in the association of head injuries with mortality. Compared with participants who did not have head injury, the HR was 1.66 (95% CI, 1.56-1.77) for those with one head injury and 2.11 (95% CI, 1.89-2.37) for those with two or more head injuries.
“It’s not as though once you’ve had one head injury, you’ve accrued all the damage you possibly can. We see pretty clearly here that recurrent head injury further increased the rate of deaths from all causes,” said Dr. Elser.
Injury severity was determined from hospital diagnostic codes using established algorithms. Results showed that mortality rates were increased with even mild head injury.
Interestingly, the association between head injury and all-cause mortality was weaker among those whose injuries were self-reported. One possibility is that these injuries were less severe, Dr. Elser noted.
“If you have head injury that’s mild enough that you don’t need to go to the hospital, it’s probably going to confer less long-term health risks than one that’s severe enough that you needed to be examined in an acute care setting,” she said.
Results were similar by race and for sex. “Even though there were more women with head injuries, the rate of mortality associated with head injury doesn’t differ from the rate among men,” Dr. Elser reported.
However, the association was stronger among those younger than 54 years at baseline (HR, 2.26) compared with older individuals (HR, 2.0) in the model that adjusted for demographics and lifestyle factors.
This may be explained by the reference group (those without a head injury) – the mortality rate was in general higher for the older participants, said Dr. Elser. It could also be that younger adults are more likely to have severe head injuries from, for example, motor vehicle accidents or violence, she added.
These new findings underscore the importance of public health measures, such as seatbelt laws, to reduce head injuries, the investigators note.
They add that clinicians with patients at risk for head injuries may recommend steps to lessen the risk of falls, such as having access to durable medical equipment, and ensuring driver safety.
Shorter life span
Commenting for this news organization, Frank Conidi, MD, director of the Florida Center for Headache and Sports Neurology in Port St. Lucie and past president of the Florida Society of Neurology, said the large number of participants “adds validity” to the finding that individuals with head injury are likely to have a shorter life span than those who do not suffer head trauma – and that this “was not purely by chance or from other causes.”
However, patients may not have accurately reported head injuries, in which case the rate of injury in the self-report subgroup would not reflect the actual incidence, noted Dr. Conidi, who was not involved with the research.
“In my practice, most patients have little knowledge as to the signs and symptoms of concussion and traumatic brain injury. Most think there needs to be some form of loss of consciousness to have a head injury, which is of course not true,” he said.
Dr. Conidi added that the finding of a higher incidence of death from neurodegenerative disorders supports the generally accepted consensus view that about 30% of patients with traumatic brain injury experience progression of symptoms and are at risk for early dementia.
The ARIC study is supported by the National Heart, Lung, and Blood Institute. Dr. Elser and Dr. Conidi have reported no relevant financial relationships.

An analysis of more than 13,000 adult participants in the Atherosclerosis Risk in Communities (ARIC) study showed a dose-response pattern in which one head injury was linked to a 66% increased risk for all-cause mortality, and two or more head injuries were associated with twice the risk in comparison with no head injuries.
These findings underscore the importance of preventing head injuries and of swift clinical intervention once a head injury occurs, lead author Holly Elser, MD, PhD, department of neurology, Hospital of the University of Pennsylvania, Philadelphia, told this news organization.
“Clinicians should counsel patients who are at risk for falls about head injuries and ensure patients are promptly evaluated in the hospital setting if they do have a fall – especially with loss of consciousness or other symptoms, such as headache or dizziness,” Dr. Elser added.
The findings were published online in JAMA Neurology.
Consistent evidence
There is “pretty consistent evidence” that mortality rates are increased in the short term after head injury, predominantly among hospitalized patients, Dr. Elser noted.
“But there’s less evidence about the long-term mortality implications of head injuries and less evidence from adults living in the community,” she added.
The analysis included 13,037 participants in the ARIC study, an ongoing study involving adults aged 45-65 years who were recruited from four geographically and racially diverse U.S. communities. The mean age at baseline (1987-1989) was 54 years; 57.7% were women; and 27.9% were Black.
Study participants are followed at routine in-person visits and semiannually via telephone.
Data on head injuries came from hospital diagnostic codes and self-reports. These reports included information on the number of injuries and whether the injury required medical care and involved loss of consciousness.
During the 27-year follow-up, 18.4% of the study sample had at least one head injury. Injuries occurred more frequently among women, which may reflect the predominance of women in the study population, said Dr. Elser.
Overall, about 56% of participants died during the study period. The estimated median amount of survival time after head injury was 4.7 years.
The most common causes of death were neoplasm, cardiovascular disease, and neurologic disorders. Regarding specific neurologic causes of death, the researchers found that 62.2% of deaths were due to neurodegenerative disease among individuals with head injury, vs. 51.4% among those without head injury.
This, said Dr. Elser, raises the possibility of reverse causality. “If you have a neurodegenerative disorder like Alzheimer’s disease dementia or Parkinson’s disease that leads to difficulty walking, you may be more likely to fall and have a head injury. The head injury in turn may lead to increased mortality,” she noted.
However, she stressed that the data on cause-specific mortality are exploratory. “Our research motivates future studies that really examine this time-dependent relationship between neurodegenerative disease and head injuries,” Dr. Elser said.
Dose-dependent response
In the unadjusted analysis, the hazard ratio of mortality among individuals with head injury was 2.21 (95% confidence interval, 2.09-2.34) compared with those who did not have head injury.
The association remained significant with adjustment for sociodemographic factors (HR, 1.99; 95% CI, 1.88-2.11) and with additional adjustment for vascular risk factors (HR, 1.92; 95% CI, 1.81-2.03).
The findings also showed a dose-response pattern in the association of head injuries with mortality. Compared with participants who did not have head injury, the HR was 1.66 (95% CI, 1.56-1.77) for those with one head injury and 2.11 (95% CI, 1.89-2.37) for those with two or more head injuries.
“It’s not as though once you’ve had one head injury, you’ve accrued all the damage you possibly can. We see pretty clearly here that recurrent head injury further increased the rate of deaths from all causes,” said Dr. Elser.
Injury severity was determined from hospital diagnostic codes using established algorithms. Results showed that mortality rates were increased with even mild head injury.
Interestingly, the association between head injury and all-cause mortality was weaker among those whose injuries were self-reported. One possibility is that these injuries were less severe, Dr. Elser noted.
“If you have head injury that’s mild enough that you don’t need to go to the hospital, it’s probably going to confer less long-term health risks than one that’s severe enough that you needed to be examined in an acute care setting,” she said.
Results were similar by race and for sex. “Even though there were more women with head injuries, the rate of mortality associated with head injury doesn’t differ from the rate among men,” Dr. Elser reported.
However, the association was stronger among those younger than 54 years at baseline (HR, 2.26) compared with older individuals (HR, 2.0) in the model that adjusted for demographics and lifestyle factors.
This may be explained by the reference group (those without a head injury) – the mortality rate was in general higher for the older participants, said Dr. Elser. It could also be that younger adults are more likely to have severe head injuries from, for example, motor vehicle accidents or violence, she added.
These new findings underscore the importance of public health measures, such as seatbelt laws, to reduce head injuries, the investigators note.
They add that clinicians with patients at risk for head injuries may recommend steps to lessen the risk of falls, such as having access to durable medical equipment, and ensuring driver safety.

Don’t cross the friends line with patients
All that moving can make it hard to maintain friendships. Factor in the challenges from the pandemic, and a physician’s life can be lonely. So, when a patient invites you for coffee or a game of pickleball, do you accept? For almost one-third of the physicians who responded to the Medscape Physician Friendships: The Joys and Challenges 2022, the answer might be yes.
About 29% said they develop friendships with patients. However, a lot depends on the circumstances. As one physician in the report said: “I have been a pediatrician for 35 years, and my patients have grown up and become productive adults in our small, rural, isolated area. You can’t help but know almost everyone.”
As the daughter of a cardiologist, Nishi Mehta, MD, a radiologist and founder of the largest physician-only Facebook group in the country, grew up with that small-town-everyone-knows-the-doctor model.
“When I was a kid, I’d go to the mall, and my friends and I would play a game: How long before a patient [of my dad’s] comes up to me?” she said. At the time, Dr. Mehta was embarrassed, but now she marvels that her dad knew his patients so well that they would recognize his daughter in crowded suburban mall.
In other instances, a physician may develop a friendly relationship after a patient leaves their care. For example, Leo Nissola, MD, now a full-time researcher and immunotherapy scientist in San Francisco, has stayed in touch with some of the patients he treated while at the University of Texas MD Anderson Cancer Center, Houston.
Dr. Nissola said it was important to stay connected with the patients he had meaningful relationships with. “It becomes challenging, though, when a former patient asks for medical advice.” At that moment, “you have to be explicitly clear that the relationship has changed.”
A hard line in the sand
The blurring of lines is one reason many doctors refuse to befriend patients, even after they are no longer treating them. The American College of Physicians Ethics Manual advises against treating anyone with whom you have a close relationship, including family and friends.
“Friendships can get in the way of patients being honest with you, which can interfere with medical care,” Dr. Mehta said. “If a patient has a concern related to something they wouldn’t want you to know as friends, it can get awkward. They may elect not to tell you.”
And on the flip side, friendship can provide a view into your private life that you may not welcome in the exam room.
“Let’s say you go out for drinks [with a patient], and you’re up late, but you have surgery the next day,” said Brandi Ring, MD, an ob.gyn. and the associate medical director at the Center for Children and Women in Houston. Now, one of your patients knows you were out until midnight when you had to be in the OR at 5:00 a.m.
Worse still, your relationship could color your decisions about a patient’s care, even unconsciously. It can be hard to maintain objectivity when you have an emotional investment in someone’s well-being.
“We don’t necessarily treat family and friends to the standards of medical care,” said Dr. Ring. “We go above and beyond. We might order more tests and more scans. We don’t always follow the guidelines, especially in critical illness.”
For all these reasons and more, the ACP advises against treating friends.
Put physician before friend
But adhering to those guidelines can lead physicians to make some painful decisions. Cutting yourself off from the possibility of friendship is never easy, and the Medscape report found that physicians tend to have fewer friends than the average American.
“Especially earlier in my practice, when I was a young parent, and I would see a lot of other young parents in the same stage in life, I’d think, ‘In other circumstances, I would be hanging out at the park with this person,’ “ said Kathleen Rowland, MD, a family medicine physician and vice chair of education in the department of family medicine at Rush University, Chicago. “But the hard part is, the doctor-patient relationship always comes first.”
To a certain extent, one’s specialty may determine the feasibility of becoming friends with a patient. While Dr. Mehta has never done so, as a radiologist, she doesn’t usually see patients repeatedly. Likewise, a young gerontologist may have little in common with his octogenarian patients. And an older pediatrician is not in the same life stage as his patients’ sleep-deprived new parents, possibly making them less attractive friends.
However, practicing family medicine is all about long-term physician-patient relationships. Getting to know patients and their families over many years can lead to a certain intimacy. Dr. Rowland said that, while a wonderful part of being a physician is getting that unique trust whereby patients tell you all sorts of things about their lives, she’s never gone down the friendship path.
“There’s the assumption I’ll take care of someone for a long period of time, and their partner and their kids, maybe another generation or two,” Dr. Rowland said. “People really do rely on that relationship to contribute to their health.”
Worse, nowadays, when people may be starved for connection, many patients want to feel emotionally close and cared for by their doctor, so it’d be easy to cross the line. While patients deserve a compassionate, caring doctor, the physician is left to walk the line between those boundaries. Dr. Rowland said, “It’s up to the clinician to say: ‘My role is as a doctor. You deserve caring friends, but I have to order your mammogram and your blood counts. My role is different.’ ”
Friendly but not friends
It can be tricky to navigate the boundary between a cordial, warm relationship with a patient and that patient inviting you to their daughter’s wedding.
“People may mistake being pleasant and friendly for being friends,” said Larry Blosser, MD, chief medical officer at Central Ohio Primary Care, Westerville. In his position, he sometimes hears from patients who have misunderstood their relationship with a doctor in the practice. When that happens, he advises the physician to consider the persona they’re presenting to the patient. If you’re overly friendly, there’s the potential for confusion, but you can’t be aloof and cold, he said.
Maintaining that awareness helps to prevent a patient’s offhand invitation to catch a movie or go on a hike. And verbalizing it to your patients can make your relationship clear from the get-go.
“I tell patients we’re a team. I’m the captain, and they’re my MVP. When the match is over, whatever the results, we’re done,” said Karenne Fru, MD, PhD, a fertility specialist at Oma Fertility Atlanta. Making deep connections is essential to her practice, so Dr. Fru structures her patient interactions carefully. “Infertility is such an isolating experience. While you’re with us, we care about what’s going on in your life, your pets, and your mom’s chemo. We need mutual trust for you to be compliant with the care.”
However, that approach won’t work when you see patients regularly, as with family practice or specialties that see the same patients repeatedly throughout the year. In those circumstances, the match is never over but one in which the onus is on the physician to establish a friendly yet professional rapport without letting your self-interest, loneliness, or lack of friends interfere.
“It’s been a very difficult couple of years for a lot of us. Depending on what kind of clinical work we do, some of us took care of healthy people that got very sick or passed away,” Dr. Rowland said. “Having the chance to reconnect with people and reestablish some of that closeness, both physical and emotional, is going to be good for us.”
Just continue conveying warm, trusting compassion for your patients without blurring the friend lines.

Dr. Rowland said that, while a wonderful part of being a physician is getting that unique trust whereby patients tell you all sorts of things about their lives, she’s never gone down the friendship path.
“There’s the assumption I’ll take care of someone for a long period of time, and their partner and their kids, maybe another generation or two,” Dr. Rowland said. “People really do rely on that relationship to contribute to their health.”
Worse, nowadays, when people may be starved for connection, many patients want to feel emotionally close and cared for by their doctor, so it’d be easy to cross the line. While patients deserve a compassionate, caring doctor, the physician is left to walk the line between those boundaries. Dr. Rowland said, “It’s up to the clinician to say: ‘My role is as a doctor. You deserve caring friends, but I have to order your mammogram and your blood counts. My role is different.’ ”
Friendly but not friends
It can be tricky to navigate the boundary between a cordial, warm relationship with a patient and that patient inviting you to their daughter’s wedding.
“People may mistake being pleasant and friendly for being friends,” said Larry Blosser, MD, chief medical officer at Central Ohio Primary Care, Westerville. In his position, he sometimes hears from patients who have misunderstood their relationship with a doctor in the practice. When that happens, he advises the physician to consider the persona they’re presenting to the patient. If you’re overly friendly, there’s the potential for confusion, but you can’t be aloof and cold, he said.
Maintaining that awareness helps to prevent a patient’s offhand invitation to catch a movie or go on a hike. And verbalizing it to your patients can make your relationship clear from the get-go.
“I tell patients we’re a team. I’m the captain, and they’re my MVP. When the match is over, whatever the results, we’re done,” said Karenne Fru, MD, PhD, a fertility specialist at Oma Fertility Atlanta. Making deep connections is essential to her practice, so Dr. Fru structures her patient interactions carefully. “Infertility is such an isolating experience. While you’re with us, we care about what’s going on in your life, your pets, and your mom’s chemo. We need mutual trust for you to be compliant with the care.”
However, that approach won’t work when you see patients regularly, as with family practice or specialties that see the same patients repeatedly throughout the year. In those circumstances, the match is never over but one in which the onus is on the physician to establish a friendly yet professional rapport without letting your self-interest, loneliness, or lack of friends interfere.
“It’s been a very difficult couple of years for a lot of us. Depending on what kind of clinical work we do, some of us took care of healthy people that got very sick or passed away,” Dr. Rowland said. “Having the chance to reconnect with people and reestablish some of that closeness, both physical and emotional, is going to be good for us.”
Just continue conveying warm, trusting compassion for your patients without blurring the friend lines.
