Watching TV, using computer have opposite ties to dementia risk
The relationship to dementia with these activities remained strong no matter how much physical activity a person did, the authors wrote in Proceedings of the National Academy of Sciences.
Both watching TV and using a computer have been linked to increased risk of chronic disease and mortality, while exercise and physical activity (PA) have shown benefit in reducing cognitive decline, structural brain atrophy, and dementia risk in older adults, the authors wrote.
The authors said they wanted to try to understand the effects of watching TV and using computers on dementia risk, because people in the United States and Europe have been engaging in both of these activities more often.
They concluded that it’s not the sitting part of sedentary behavior (SB) that potentially has the effect on dementia but what people are doing while sitting.
Some of the results were surprising, lead author David Raichlen, PhD, professor of Human and Evolutionary Biology at University of Southern California, Los Angeles, said in an interview.
Previous literature on sedentary behaviors have documented their negative effects on a wide range of health outcomes, rather than finding positive associations, he explained.
More than 140,000 included in study
The researchers conducted their prospective cohort study using data from the United Kingdom Biobank. After excluding people younger than 60, those with prevalent dementia at the start of follow-up, and those without complete data, 146,651 participants were included.
The participants were followed from their baseline visit until they received a dementia diagnosis, died, were lost to follow-up, or were last admitted to the hospital.
TV-watching time was linked with an increased risk of incident dementia (HR [95% confidence interval] = 1.31 [1.23-1.40]), and computer use was linked with a reduced risk of incident dementia HR [95% CI] = 0.80 [0.76-0.85]).
TV’s link with higher dementia risk increased in those who had the highest use, compared with those who had the lowest use (HR [95% CI] = 1.28 [1.18-1.39].
Similarly, the link with risk reduction for dementia with computer use increased with more use.
Both medium and high computer time were associated with reduced risk of incident dementia (HR [95% CI] = 0.70 [0.64-0.76] and HR [95% CI] = 0.76 [0.70-0.83] respectively).
Dr. Raichlen pointed out that the high use of TV in this study was 4 or more hours a day and computer use – which included leisure use, not work use – had benefits on dementia risk after just half an hour.
These results remained significant after researchers adjusted for demographic, health, and lifestyle variables, including time spent on physical activity, sleeping, obesity, alcohol consumption, smoking status, diet scores, education level, body mass index, and employment type.
Physical is still better than sedentary activity
One potential reason for the different effects on dementia risk in the two activities studied, the authors write, is that sitting down to watch TV is associated with “uniquely low levels of muscle activity and energy expenditure, compared with sitting to use a computer.”
Andrew Budson, MD, chief of Cognitive & Behavioral Neurology and Associate Chief of Staff for Education for the VA Boston Healthcare System, Mass., who was not part of the study, said he thinks a more likely explanation for the study findings lies in the active versus passive tasks required in the two kinds of viewing that the authors reference.
“When we’re doing cognitive activity involving using the computer, we’re using large parts of our cortex to carry out that activity, whereas when we’re watching TV, there are probably relatively small amounts of our brain that are actually active,” Dr. Budson, author of Seven Steps to Managing Your Memory, explained in an interview.
“This is one of the first times I’ve been convinced that even when the computer activity isn’t completely new and novel, it may be beneficial,” Dr. Budson said.
It would be much better to do physical activity, but if the choice is sedentary activity, active cognitive activities, such as computer use, are better than TV watching, he continued.
The results of the current study are consistent with previous work showing that the type of sedentary behavior matters, according to the authors.
“Several studies have shown that TV time is associated with mortality and poor cardiometabolic biomarkers, whereas computer time is not,” they wrote.
A limitation of the study is that sedentary behaviors were self-reported via questionnaires, and there may be errors in recall.
“The use of objective methods for measuring both SB and PA are needed in future studies,” they write.

Can folic acid halt or reverse progression of gastric precancerous conditions?
Folic acid supplementation can improve histopathologic aspects of gastric precancerous conditions (GPC), including gastric mucosal atrophy and intestinal metaplasia, according to results of a meta-analysis of relevant research.
The results, say the authors, provide evidence for the potential clinical use of folic acid in the management of GPC.
“We believe doctors can try to use folic acid to halt or reverse progression of gastric precancerous conditions, thereby reducing the incidence rate of gastric cancer,” investigator Jinhao Zeng, PhD, with Hospital of Chengdu University of Traditional Chinese Medicine, said in an interview.
Dr. Zeng cautioned, however, that the number of relevant studies “remains relatively inadequate, and the results should be interpreted with caution.”
David Johnson, MD, professor of medicine and chief of gastroenterology at the Eastern Virginia School of Medicine, Norfolk, who wasn’t involved in the study, also urged caution in interpreting the results.
“Overall, folate supplementation is unlikely to be harmful, but these data should not be used as justification for risk reduction,” Dr. Johnson said in an interview.
The study was published online in BMC Gastroenterology.
Examining prevention, treatment effects
The study is believed to be the first meta-analysis to examine the effects of folic acid on prevention and treatment for patients with GPC. The analysis included 13 randomized controlled trials that had a total of 1,252 adults with GPC living in China.
A meta-analysis of five studies showed a statistically significant positive treatment effect of folic acid supplementation on gastric mucosal atrophy (relative risk, 1.61; 95% confidence interval 1.07 – 2.41), Dr. Zeng and colleagues reported.
A meta-analysis of two trials showed a statistically significant effect of folic acid on reversal of intestinal metaplasia (RR, 1.77; 95% CI, 1.32-2.37), they also found.
“Our study indicates that folic acid has a beneficial effect in the treatment of pathological changes of GPC when the dose was maintained at 20-30 mg/d and the duration of treatment was maintained at 3-6 months,” they wrote.
Folic acid supplementation did not appear to be effective for GPC symptom relief.
The authors said that, in a separate analysis, they confirmed that folic acid can inhibit development of gastric mucosal carcinogenesis by affecting the levels of gastrin and pepsinogen.
More study needed
Commenting on the study, Judith Kim, MD, division of gastroenterology and hepatology, New York University Langone Health, said prior studies have evaluated whether folic acid supplementation is associated with a lower risk of gastric cancer, but the results have been “mixed and inconclusive.”
“While there have been prior meta-analyses on folic acid and gastric cancer, this study is noteworthy, as it evaluated the impact of folic acid on precancerous lesions, for which there is no current treatment,” Dr. Kim said.
“Currently, there is no recommendation for folic acid supplementation for the treatment or prevention of GPC and gastric cancer,” Dr. Kim said. “There has been interest in folic acid as a chemopreventive agent, given its potential protective role against DNA damage, but randomized control trials have yet to confirm these benefits.”
The analysis by Dr. Zeng and colleagues “supports the need for larger randomized controlled trials to further study this association,” Dr. Kim said.
“Given the study’s small size and limitation to a Chinese population (who have a higher incidence of precancerous lesions and gastric cancer than the general US population), I would caution against folic acid use for the sole purpose of GPC prevention, as there could be negative side effects of supplementation,” she advised.
The study was supported by the National Natural Science Foundation of China, the Hospital of Chengdu University of Traditional Chinese Medicine, and Project of Sichuan Administration of Traditional Chinese Medicine. Dr. Zeng, Dr. Johnson, and Dr. Kim reported no relevant financial relationships.

Antibiotic before oral surgery spares endocarditis; study validates guidelines
The strongest evidence yet to support clinical guidelines that recommend that people at high risk of endocarditis, such as those who’ve had previous episode the disease or who have a prosthetic cardiac valve, should take antibiotics before they have a tooth pulled or other types of oral surgery, comes from a new study that used two methodologies.
But it also pointed out that two-thirds of the time they aren’t getting that type of antibiotic coverage.
The researchers conducted a cohort study of almost 8 million retirees with employer-paid Medicare supplemental prescription benefits and dental benefits, then conducted a case-crossover study of 3,774 people from the cohort who’d been hospitalized with infectious endocarditis (IE) and who had invasive dental procedures. The bottom line is that the study supports the clinical guidelines from the American Heart Association and the European Society of Cardiology that recommend antibiotic prophylaxis (AP) before dental procedures for patients at high-risk of IE.
Likewise, lead author Martin Thornhill, MBBS, BDS, PhD, said in an interview, the findings also suggest that existing guidelines in the United Kingdom, which recommend against AP in these patients, “should be reconsidered.”
Those AHA and ESC guidelines, however, are “based on no good quality evidence,” said Dr. Thornhill, professor of translational research in dentistry at the University of Sheffield (England) School of Clinical Dentistry. “Other studies have looked at this, but we’ve done the largest study that has shown the clear association between invasive dental procedures and subsequent development of infective endocarditis.”
In the entire cohort of 7.95 million patients, 3,774 had cases of IE that required hospitalization. The study defined highest risk of IE as meeting one of these six criteria: a previous case of IE; a prosthetic cardiac valve or a valve repair that used prosthetic material; cyanotic congenital heart disease; palliative shunts or conduits to treat CHD; or a congenital heart defect that had been fully repaired, either by surgery or a transcatheter procedure, with prosthetic material or device – the latter within 6 months of the procedure.
Moderate IE risk included patients who had rheumatic heart disease, nonrheumatic valve disease or congenital valve anomalies—including mitral valve prolapse or aortic stenosis—or hypertrophic cardiomyopathy.
Risk classification and poor compliance
Highest-risk patients had significantly higher rates of IE a month after a dental procedure than lower-risk groups: 467.6 cases per 1 million procedures vs. 24.2 for moderate risk and 3.8 for low or unknown risk. A subanalysis found that the odds of IE were significantly increased for two specific dental procedures: extractions, with an odds ratio of 9.22 (95% confidence interval [CI], 5.54-15.88; P < .0001); and other oral surgical procedures, with an OR of 20.18 (95% CI, 11.22-37.74; P < .0001).
The study also found that 32.6% of the high-risk patients undergoing dental procedures got AP. “Clearly that shows a low level of compliance with the guidelines in the U.S.,” Dr. Thornhill said. “That’s something that needs to be addressed.”
The study was unique in that it used both a population cohort study and the case-crossover study. “It didn’t matter which of the two methods we used; we essentially came to the same result, which I think adds further weight to the findings,” Dr. Thornhill said.
This may be the best evidence to support the guidelines that clinicians may get. While the observational nature of this study has its limitations, conducting a randomized clinical trial to further validate the findings would be “logistically impossible,” he said, in that it would require an “absolutely enormous” cohort and coordination between medical and dental databases covering thousands of lives. An RCT would also require not using AP for some patients. “It’s not ethical to keep somebody off of antibiotic prophylaxis when there’s such a high risk of death and severe outcomes,” Dr. Thornhill said.
Ann Bolger, MD, emeritus professor of medicine at the University of California, San Francisco, and coauthor of an editorial comment on the study, said in an interview that this study is noteworthy not only for its dual methodology, but for the quality of the data that matched patients at high risk for IE with prescription and dental records. “The fact that they were able to have those details in enough granularity that they knew whether a dental procedure was likely to meet the criteria for these more invasive exposures really broke it open from my perspective,” she said.
She called the low compliance rate with AHA guidelines “one of the most sobering points of this,” and said it should put clinicians on notice that they must do more to educate and engage with high-risk patients. “The lines of communication here are somewhat fraught; it’s a little bit of a hot potato,” she said. “It’s a really great communications opportunity to get the provider’s attention back on this. You’re a cardiologist; you have to have this conversation when you see your patient with a prosthetic valve or who’s had endocarditis every time they come in. There’s a whole litany, and it takes 3 minutes, but you have to do it.”
The study received funding from Delta Dental of Michigan Research Committee and Renaissance Health Service Corp., and Dr. Thornhill received support from Delta Dental Research and Data Institute for the study. Dr. Bolger participated in the 2007 and 2021 AHA statements on AP to prevent IE.

She called the low compliance rate with AHA guidelines “one of the most sobering points of this,” and said it should put clinicians on notice that they must do more to educate and engage with high-risk patients. “The lines of communication here are somewhat fraught; it’s a little bit of a hot potato,” she said. “It’s a really great communications opportunity to get the provider’s attention back on this. You’re a cardiologist; you have to have this conversation when you see your patient with a prosthetic valve or who’s had endocarditis every time they come in. There’s a whole litany, and it takes 3 minutes, but you have to do it.”
The study received funding from Delta Dental of Michigan Research Committee and Renaissance Health Service Corp., and Dr. Thornhill received support from Delta Dental Research and Data Institute for the study. Dr. Bolger participated in the 2007 and 2021 AHA statements on AP to prevent IE.
The strongest evidence yet to support clinical guidelines that recommend that people at high risk of endocarditis, such as those who’ve had previous episode the disease or who have a prosthetic cardiac valve, should take antibiotics before they have a tooth pulled or other types of oral surgery, comes from a new study that used two methodologies.
But it also pointed out that two-thirds of the time they aren’t getting that type of antibiotic coverage.
The researchers conducted a cohort study of almost 8 million retirees with employer-paid Medicare supplemental prescription benefits and dental benefits, then conducted a case-crossover study of 3,774 people from the cohort who’d been hospitalized with infectious endocarditis (IE) and who had invasive dental procedures. The bottom line is that the study supports the clinical guidelines from the American Heart Association and the European Society of Cardiology that recommend antibiotic prophylaxis (AP) before dental procedures for patients at high-risk of IE.
Likewise, lead author Martin Thornhill, MBBS, BDS, PhD, said in an interview, the findings also suggest that existing guidelines in the United Kingdom, which recommend against AP in these patients, “should be reconsidered.”
Those AHA and ESC guidelines, however, are “based on no good quality evidence,” said Dr. Thornhill, professor of translational research in dentistry at the University of Sheffield (England) School of Clinical Dentistry. “Other studies have looked at this, but we’ve done the largest study that has shown the clear association between invasive dental procedures and subsequent development of infective endocarditis.”
In the entire cohort of 7.95 million patients, 3,774 had cases of IE that required hospitalization. The study defined highest risk of IE as meeting one of these six criteria: a previous case of IE; a prosthetic cardiac valve or a valve repair that used prosthetic material; cyanotic congenital heart disease; palliative shunts or conduits to treat CHD; or a congenital heart defect that had been fully repaired, either by surgery or a transcatheter procedure, with prosthetic material or device – the latter within 6 months of the procedure.
Moderate IE risk included patients who had rheumatic heart disease, nonrheumatic valve disease or congenital valve anomalies—including mitral valve prolapse or aortic stenosis—or hypertrophic cardiomyopathy.
Risk classification and poor compliance
Highest-risk patients had significantly higher rates of IE a month after a dental procedure than lower-risk groups: 467.6 cases per 1 million procedures vs. 24.2 for moderate risk and 3.8 for low or unknown risk. A subanalysis found that the odds of IE were significantly increased for two specific dental procedures: extractions, with an odds ratio of 9.22 (95% confidence interval [CI], 5.54-15.88; P < .0001); and other oral surgical procedures, with an OR of 20.18 (95% CI, 11.22-37.74; P < .0001).
The study also found that 32.6% of the high-risk patients undergoing dental procedures got AP. “Clearly that shows a low level of compliance with the guidelines in the U.S.,” Dr. Thornhill said. “That’s something that needs to be addressed.”
The study was unique in that it used both a population cohort study and the case-crossover study. “It didn’t matter which of the two methods we used; we essentially came to the same result, which I think adds further weight to the findings,” Dr. Thornhill said.
This may be the best evidence to support the guidelines that clinicians may get. While the observational nature of this study has its limitations, conducting a randomized clinical trial to further validate the findings would be “logistically impossible,” he said, in that it would require an “absolutely enormous” cohort and coordination between medical and dental databases covering thousands of lives. An RCT would also require not using AP for some patients. “It’s not ethical to keep somebody off of antibiotic prophylaxis when there’s such a high risk of death and severe outcomes,” Dr. Thornhill said.

Higher rates of group B strep disease found in Black and Asian newborns
Health charities called for action to address racial health disparities after population-wide analysis by the UK Health Security Agency found that Black and Asian neonates had a significantly higher risk of early-onset group B streptococcal disease (GBS), compared with White infants.
One support group said more research was now needed to identify the cause of the disparity, and called for pregnant women to be better informed about the disease and what it could mean for them and their baby.
The study, published in Pediatrics, used UKHSA data on laboratory-confirmed infant group B streptococcal (iGBS) disease cases between Jan. 1, 2016, and Dec. 31, 2020, and were linked to hospital ethnicity records.
Cases of iGBS were defined as isolation of Streptococcus agalactiae from a normally sterile site at 0-6 days of life for early-onset iGBS and 7-90 days for late-onset disease.
Hospital data and parent-reported ethnicity
Researchers found 2,512 iGBS cases in England during the study period, 65.3% were early onset and 34.8% late onset, equivalent to 0.52 and 0.28 cases per 1000 live births respectively.
Researchers were able to link 85.6% of those to ethnicity. Among those 2,149 cases, Black infants had a 48% higher risk, and Asian infants a 40% higher risk of early onset iGBS, compared with White infants. Among those from an Asian background, the risk was 87% higher for Bangladeshi and 38% higher for Pakistani neonates.
Rates of early onset iGBS per 1,000 live births were 0.43 for White infants, 0.63 for Black infants, and 0.60 for those of Asian ethnicity.
In contrast, Indian infants had an early-onset rate of 0.47 per 1,000 live births, which was similar to White infants.
Black infants had 57% higher rates of late-onset iGBS (0.37) than White infants (0.24), the researchers reported.
The study authors highlighted previous research which found higher prevalence of group B streptococcal colonization in mothers from Black and some Asian ethnic groups, but lower prevalence in mothers from the Indian subcontinent. More research was needed to establish causes, the researchers said, including whether higher preterm birth rates in minority ethnic groups led to increased iGBS risk in neonates, or whether maternal group B streptococcal disease led to higher preterm birth rates and subsequent neonatal iGBS.
The researchers concluded: “Understanding the factors underpinning differences in rates of early-onset iGBS within south Asian groups in England may lead to new opportunities for prevention such as prioritized antenatal screening. Strategies to prevent neonatal iGBS must be tailored from high-quality quantitative and qualitative data to reach all women and protect all infants, irrespective of racial or ethnic background.”
‘Shocking but not surprising’
Commenting on the study, Edward Morris, president of the Royal College of Obstetricians and Gynaecologists, said: “This research is striking reading, and is yet another example of how far we have to go to tackle health inequalities within women’s health care.”
Philip Steer, professor emeritus at Imperial College London, said that the results were “consistent with previous reports of higher GBS carriage and higher maternal and neonatal mortality rates in minority groups” and “emphasize the importance of studying not just whether, but why, these differences exist.” He added: “We need to understand the reasons for the differences before we can design much-needed intervention to eliminate them.”
Jane Plumb, chief executive of Group B Strep Support, called the findings “shocking, but unfortunately not surprising” and said that they offered “another example of racial disparities in maternal and neonatal health.” She said: “We’re calling for all pregnant women and birthing people to be informed about GBS and its risks, so they can make empowered choices for themselves and their baby. It is also critical that trusts sign up to take part in the internationally significant [National Institute for Health and Care Research]–funded GBS3 clinical trial, designed to improve the prevention of GBS infection.”
Baroness Shaista Gohir, chief executive of the Muslim Women’s Network, said: “With significantly higher rates of group B Strep infection in Black and Asian babies, greater efforts must be made to improve awareness among pregnant women within these communities.”

Indiana’s new abortion ban may drive some young ob.gyns. to leave a state where they’re needed
On a Monday morning, a group of obstetrics and gynecology residents, dressed in blue scrubs and white coats, gathered in an auditorium at Indiana University, Indianapolis. After the usual updates and announcements, Nicole Scott, MD, the residency program director, addressed the elephant in the room. “Any more abortion care questions?” she asked the trainees.
After a few moments of silence, one resident asked: “How’s Dr. Bernard doing?”
“Bernard is actually in really good spirits – I mean, relatively,” Dr. Scott answered. “She has 24/7 security, has her own lawyer.”
They were talking about Caitlin Bernard, MD, an Indiana ob.gyn. who provides abortions and trains residents at the university hospital. Dr. Bernard was recently caught in a political whirlwind after she spoke about an abortion she provided to a 10-year-old rape victim from Ohio. Dr. Bernard was the target of false accusations made on national television by pundits and political leaders, including Indiana’s attorney general.
The doctors interviewed for this article said that they are not speaking on behalf of their school of medicine but rather about their personal experiences during a tumultuous moment that they worry will affect the way they care for their patients.
The vitriol directed at Dr. Bernard hit home for this group of residents. She has mentored most of them for years. Many of the young doctors were certain they wanted to practice in Indiana after their training. But lately, some have been ambivalent about that prospect.
Beatrice Soderholm, DO, a fourth-year ob.gyn. resident, said watching what Dr. Bernard went through was “scary.” “I think that was part of the point for those who were putting her through that,” Dr. Soderholm said. They were trying “to scare other people out of doing the work that she does.”
In early August, Gov. Eric Holcomb, a Republican, signed a near-total abortion ban into law, making Indiana the first state to adopt new restrictions on abortion access since the Supreme Court struck down Roe v. Wade in June. When the ban takes effect Sept. 15, medical providers who violate the law risk losing their licenses or serving up to six years in prison.
These days, Dr. Scott, the residency program director, uses some meeting time with residents to fill them in on political updates and available mental health services. She also reminds them that legal counsel is on call round the clock to help if they’re ever unsure about the care they should provide a patient.
“Our residents are devastated,” Dr. Scott said, holding back tears. “They signed up to provide comprehensive health care to women, and they are being told that they can’t do that.”
She expects this will “deeply impact” how Indiana hospitals recruit and retain medical professionals.
A 2018 report from the March of Dimes found that 27% of Indiana counties are considered maternity care deserts, with no or limited access to maternal care. The state has one of the nation’s highest maternal mortality rates.
Dr. Scott said new laws restricting abortion will only worsen those statistics.
Dr. Scott shared results from a recent survey of nearly 1,400 residents and fellows across all specialties at IU, nearly 80% of the trainees said they were less likely to stay and practice in Indiana after the abortion ban.
Wendy Tian, MD, a third-year resident, said she is worried about her safety. Dr. Tian grew up and went to medical school in Chicago and chose to do her residency in Indiana because the program has a strong family-planning focus. She was open to practicing in Indiana when she completed her training.
But that’s changed.
“I, for sure, don’t know if I would be able to stay in Indiana post graduation with what’s going on,” Dr. Tian said.
Still, she feels guilty for “giving up” on Indiana’s most vulnerable patients.
Even before Roe fell, Dr. Tian said, the climate in Indiana could be hostile and frustrating for ob.gyns. Indiana, like other states with abortion restrictions, allows nearly all health care providers to opt out of providing care to patients having an abortion.
“We encounter other people who we work with on a daily basis who are opposed to what we do,” Dr. Tian said, adding that she and her colleagues have had to cancel scheduled procedures because the nurses on call were not comfortable assisting during an abortion.
Dr. Scott said the ob.gyn. program at the IU has provided residents with comprehensive training, including on abortion care and family planning. Since miscarriages are managed the same way as first-trimester abortions, she said, the training gives residents lots of hands-on experience. “What termination procedures allow you to do is that kind of repetition and that understanding of the female anatomy and how to manage complications that may happen with miscarriages.”
The ban on abortions dramatically reduces the hands-on opportunities for ob.gyn. residents, and that’s a huge concern, she said.
The program is exploring ways to offer training. One option is to send residents to learn in states without abortion restrictions, but Dr. Scott said that would be a logistical nightmare. “This is not as simple as just showing up to an office and saying: ‘Can I observe?’ This includes getting a medical license for out-of-state trainees. This includes funding for travel and lodging,” Dr. Scott said. “It adds a lot to what we already do to educate future ob.gyns.”
Four in 10 of all ob.gyn. residents in the United States are in states where abortion is banned or likely to be banned, so there could be a surge of residents looking to go out of state to make up for lost training opportunities. The Accreditation Council for Graduate Medical Education, the body that accredits residency programs, proposed modifications to the graduation requirements for ob.gyn. residents to account for the changing landscape.
For some of the Indiana ob.gyn. residents – including Veronica Santana, MD, a first-year resident – these political hurdles are a challenge they’re more than willing to take on. Dr. Santana is Latina, grew up in Seattle, and has been involved in community organizing since she was a teenager. One reason she chose obstetrics and gynecology was because of how the field intersects with social justice. “It’s political. It always has been, and it continues to be,” she said, “And, obviously, especially now.”
After Roe was overturned, Dr. Santana, alongside other residents and mentors, took to the streets of Indianapolis to participate in rallies in support of abortion rights.
Indiana could be the perfect battleground for Dr. Santana’s advocacy and social activism. But lately, she said, she is “very unsure” whether staying in Indiana to practice after residency makes sense, since she wants to provide the entire range of ob.gyn. services.
Dr. Soderholm, who grew up in Minnesota, has felt a strong connection to patients at the county hospital in Indianapolis. She had been certain she wanted to practice in Indiana. But her family in Minnesota – where abortion remains largely protected – has recently questioned why she would stay in a state with such a hostile climate for ob.gyns. “There’s been a lot of hesitation,” she said. But the patients make leaving difficult. “Sorry,” she said, starting to cry.
It’s for those patients that Dr. Soderholm decided she’ll likely stay. Other young doctors may make a different decision.

After the usual updates and announcements, Nicole Scott, MD, the residency program director, addressed the elephant in the room. “Any more abortion care questions?” she asked the trainees.
After a few moments of silence, one resident asked: “How’s Dr. Bernard doing?”
“Bernard is actually in really good spirits – I mean, relatively,” Dr. Scott answered. “She has 24/7 security, has her own lawyer.”
They were talking about Caitlin Bernard, MD, an Indiana ob.gyn. who provides abortions and trains residents at the university hospital. Dr. Bernard was recently caught in a political whirlwind after she spoke about an abortion she provided to a 10-year-old rape victim from Ohio. Dr. Bernard was the target of false accusations made on national television by pundits and political leaders, including Indiana’s attorney general.
The doctors interviewed for this article said that they are not speaking on behalf of their school of medicine but rather about their personal experiences during a tumultuous moment that they worry will affect the way they care for their patients.
The vitriol directed at Dr. Bernard hit home for this group of residents. She has mentored most of them for years. Many of the young doctors were certain they wanted to practice in Indiana after their training. But lately, some have been ambivalent about that prospect.
Beatrice Soderholm, DO, a fourth-year ob.gyn. resident, said watching what Dr. Bernard went through was “scary.” “I think that was part of the point for those who were putting her through that,” Dr. Soderholm said. They were trying “to scare other people out of doing the work that she does.”
In early August, Gov. Eric Holcomb, a Republican, signed a near-total abortion ban into law, making Indiana the first state to adopt new restrictions on abortion access since the Supreme Court struck down Roe v. Wade in June. When the ban takes effect Sept. 15, medical providers who violate the law risk losing their licenses or serving up to six years in prison.
These days, Dr. Scott, the residency program director, uses some meeting time with residents to fill them in on political updates and available mental health services. She also reminds them that legal counsel is on call round the clock to help if they’re ever unsure about the care they should provide a patient.
“Our residents are devastated,” Dr. Scott said, holding back tears. “They signed up to provide comprehensive health care to women, and they are being told that they can’t do that.”
She expects this will “deeply impact” how Indiana hospitals recruit and retain medical professionals.
A 2018 report from the March of Dimes found that 27% of Indiana counties are considered maternity care deserts, with no or limited access to maternal care. The state has one of the nation’s highest maternal mortality rates.
Dr. Scott said new laws restricting abortion will only worsen those statistics.
Dr. Scott shared results from a recent survey of nearly 1,400 residents and fellows across all specialties at IU, nearly 80% of the trainees said they were less likely to stay and practice in Indiana after the abortion ban.
Wendy Tian, MD, a third-year resident, said she is worried about her safety. Dr. Tian grew up and went to medical school in Chicago and chose to do her residency in Indiana because the program has a strong family-planning focus. She was open to practicing in Indiana when she completed her training.
But that’s changed.
“I, for sure, don’t know if I would be able to stay in Indiana post graduation with what’s going on,” Dr. Tian said.
Still, she feels guilty for “giving up” on Indiana’s most vulnerable patients.
Even before Roe fell, Dr. Tian said, the climate in Indiana could be hostile and frustrating for ob.gyns. Indiana, like other states with abortion restrictions, allows nearly all health care providers to opt out of providing care to patients having an abortion.
“We encounter other people who we work with on a daily basis who are opposed to what we do,” Dr. Tian said, adding that she and her colleagues have had to cancel scheduled procedures because the nurses on call were not comfortable assisting during an abortion.
Dr. Scott said the ob.gyn. program at the IU has provided residents with comprehensive training, including on abortion care and family planning. Since miscarriages are managed the same way as first-trimester abortions, she said, the training gives residents lots of hands-on experience. “What termination procedures allow you to do is that kind of repetition and that understanding of the female anatomy and how to manage complications that may happen with miscarriages.”
The ban on abortions dramatically reduces the hands-on opportunities for ob.gyn. residents, and that’s a huge concern, she said.
The program is exploring ways to offer training. One option is to send residents to learn in states without abortion restrictions, but Dr. Scott said that would be a logistical nightmare. “This is not as simple as just showing up to an office and saying: ‘Can I observe?’ This includes getting a medical license for out-of-state trainees. This includes funding for travel and lodging,” Dr. Scott said. “It adds a lot to what we already do to educate future ob.gyns.”
Four in 10 of all ob.gyn. residents in the United States are in states where abortion is banned or likely to be banned, so there could be a surge of residents looking to go out of state to make up for lost training opportunities. The Accreditation Council for Graduate Medical Education, the body that accredits residency programs, proposed modifications to the graduation requirements for ob.gyn. residents to account for the changing landscape.
For some of the Indiana ob.gyn. residents – including Veronica Santana, MD, a first-year resident – these political hurdles are a challenge they’re more than willing to take on. Dr. Santana is Latina, grew up in Seattle, and has been involved in community organizing since she was a teenager. One reason she chose obstetrics and gynecology was because of how the field intersects with social justice. “It’s political. It always has been, and it continues to be,” she said, “And, obviously, especially now.”
After Roe was overturned, Dr. Santana, alongside other residents and mentors, took to the streets of Indianapolis to participate in rallies in support of abortion rights.
Indiana could be the perfect battleground for Dr. Santana’s advocacy and social activism. But lately, she said, she is “very unsure” whether staying in Indiana to practice after residency makes sense, since she wants to provide the entire range of ob.gyn. services.
Dr. Soderholm, who grew up in Minnesota, has felt a strong connection to patients at the county hospital in Indianapolis. She had been certain she wanted to practice in Indiana. But her family in Minnesota – where abortion remains largely protected – has recently questioned why she would stay in a state with such a hostile climate for ob.gyns. “There’s been a lot of hesitation,” she said. But the patients make leaving difficult. “Sorry,” she said, starting to cry.
It’s for those patients that Dr. Soderholm decided she’ll likely stay. Other young doctors may make a different decision.

Atrial cardiopathy linked to 35% higher dementia risk
“We cautiously suggest that an understanding of this relationship might provide a basis for new interventional strategies to help thwart the development of dementia,” the authors write.
The research, led by Michelle C. Johansen, MD, department of neurology, Johns Hopkins University, Baltimore, was published online in the Journal of the American Heart Association.
Atrial cardiopathy, characterized by abnormal size and function of the left atrium, has been associated with an increased risk of stroke and atrial fibrillation (AFib), and because both stroke and AFib are associated with an increased dementia risk, the authors write, it was important to investigate whether atrial cardiopathy is linked to dementia.
If that’s the case, they reasoned, the next question was whether that link is independent of AFib and stroke, and their new research suggests that it is.
For this analysis, the researchers conducted a prospective cohort analysis of participants in the Atherosclerosis Risk in Communities (ARIC) study who were attending visit 5 (2011-2013). During their fifth, sixth, and seventh clinical visits, the ARIC participants were evaluated for cognitive decline indicating dementia.
They studied a diverse population of 5,078 older adults living in four U.S. communities: Washington County, Md.; Forsyth County, N.C.; the northwestern suburbs of Minneapolis; and Jackson, Miss.
Just more than a third (34%) had atrial cardiopathy (average age, 75 years; 59% female; 21% Black) and 763 participants developed dementia.
Investigators found that atrial cardiopathy was significantly associated with dementia (adjusted hazard ratio, 1.35 [95% confidence interval, 1.16-1.58]).
They considered ARIC participants to have atrial cardiopathy if they had at least one of the following: P-wave terminal force greater than 5,000 mV·ms in ECG lead V1; NTproBNP greater than 250 pg/mL; or left atrial volume index greater than or equal to 34 mL/m2 by transthoracic echocardiography.
The risk of dementia was even stronger when the researchers defined cardiopathy by at least two biomarkers instead of one (aHR, 1.54 [95% CI, 1.25-1.89]).
The authors point out, however, that this study is observational and cannot make a causal link.
Clifford Kavinsky, MD, PhD, head of the Comprehensive Stroke and Cardiology Clinic at Rush University Medical Center, Chicago, told this news organization that much more research would need to be done to show convincingly that atrial cardiopathy causes dementia.
He called the findings “provocative in trying to understand in a general sense how cardiac dysfunction leads to dementia.”
“We all know heart failure leads to dementia, but now we see there may be a relationship with just dysfunction of the upper chambers,” he said.
Unresolved questions
But it still not clear is what is mediating the connection, who is at risk, and how the increased risk can be prevented, he said.
He said he also wonders whether the results eliminated all patients with atrial fibrillation, a point the authors acknowledge as well.
Researchers list in the limitations that “asymptomatic AFib or silent cerebral infarction may have been missed by the ARIC adjudication process.”
There is broad understanding that preventing heart disease is important for a wide array of reasons, Dr. Kavinsky noted, and one of the reasons is cognitive deterioration.
He said this study helps identify that “even dysfunction of the upper chambers of the heart contributes to the evolution of dementia.”
The study amplifies the need to shift to prevention with heart disease in general, and more specifically in atrial dysfunction, Dr. Kavinsky said, noting a lot of atrial dysfunction is mediated by underlying hypertension and coronary disease.
Researchers evaluated cognitive decline in all participants with a comprehensive array of neuropsychological tests and interviewed some of the patients.
“A diagnosis of dementia was generated based on testing results by a computer diagnostic algorithm and then decided upon by an expert based on the Diagnostic and Statistical Manual of Mental Disorders and the criteria outlined by the National Institutes of Health and the National Institutes of Health,” they write.
Dr. Johansen reported funding from National Institute of Neurological Disorders and Stroke. Study coauthor disclosures are listed in the paper. Dr. Kavinsky has disclosed no relevant financial relationships.

Guidelines on GLP1RAs and continuous glucose monitors are among biggest news in diabetes
glucagonlike peptide-1 receptor agonists (GLP1RAs) and continuous glucose monitoring (CGM) technology. I am hoping my discussion about these major advances in this edition of Highlights will be helpful to those caring for patients with diabetes.
Tirzepatide
The first GLP1RA, exenatide, was released in April 2005. Since then, numerous daily and weekly drugs of this class have been developed. We’ve learned they are effective glucose lowering drugs, and the weekly agents dulaglutide and semaglutide have shown impressive weight reduction properties as well as cardiovascular benefits.
Secondary outcomes have also shown renal benefits to these agents, and studies for primary renal efficacy are pending. Due to all of these properties, the GLP1RAs are recommended as the first injectable for the treatment of type 2 diabetes, prior to insulin initiation.1
The next generation of these agents are a combination of a GLP1RA and a glucose-dependent insulinotropic polypeptide (GIP). Glucagonlike peptide-1 (GLP-1) stimulates insulin secretion, inhibits glucagon secretion, delays gastric emptying, and has central effects inducing satiety.
We now understand that GIP is the main incretin hormone in those without diabetes, causative of most of the incretin effects. But the insulin response after GIP secretion in type 2 diabetes is strongly reduced. It is now appreciated that this poor effect of GIP can be reduced when used in combination with a GLP1RA. This combination incretin, called by some a “twincretin,” is the basis for the drug tirzepatide which was approved by the Food and Drug Administration in May of 2022.
The data supporting this agent for both diabetes and obesity are impressive. For example, in a 40-week study with a baseline HbA1c of 8.0%, those randomized to tirzepatide at 5 mg, 10 mg, and 15 mg had HbA1c reductions of 1.87%, 1.89%, and 2.07% respectively.2 Over 81% at all doses had HbA1c levels less than 6.5% at 40 weeks.
For the 5-mg, 10-mg, and 15-mg doses, weight change from baseline was 7.9%, 9.3%, and 11.0% respectively. Like older GLP1RAs, gastrointestinal side effects were the main problem. For the three doses, 3%, 5%, and 7%, respectively, had to stop the drug, compared with the 3% who stopped taking the placebo. In another study, tirzepatide was noninferior or superior at all three doses compared with semaglutide 1 mg weekly.3
In a population without diabetes, with 40% of patients having prediabetes, weight loss percentages for the three doses were 15.0%, 19.5%, and 20.9% respectively.4 Discontinuation percentages due to side effects were 4%-7%. The exciting part is we now have a drug that approaches weight loss from bariatric surgery. The cardiovascular and renal outcome trials are now underway, but the enthusiasm for this drug is clear from the data.
Like other GLP1RAs, the key is to start low and go slowly. It is recommended to start tirzepatide at 2.5 mg four times a week, then increase to 5 mg. Due to gastrointestinal side effects, some patients will do better at the lower dose before increasing. For those switching from another GLP1RA, there are no data to guide us but, in my practice, I start those patients at 5 mg weekly.
Continuous glucose monitoring
Data continue to accumulate that this form of glycemic self-monitoring is effective to reduce HbA1c levels and minimize hypoglycemia in both type 1 and type 2 diabetes. The most important change to the 2022 American Diabetes Association (ADA) standards of care is recognizing CGM as level A evidence for those receiving basal insulin without mealtime insulin.5 There are four CGMs on the market, but most of the market uses the Dexcom G6 or the Libre 2. Both of these devices will be updated within the next few months to newer generation sensors.
While there are similarities and differences between the two devices, by late 2022 and early 2023 changes to both will reduce the dissimilarities.
The next generation Libre (Libre 3) will be continuous, and “scanning” will no longer be required. For those unable to get insurance to cover CGM, the Libre will continue to be more affordable than the Dexcom. Alerts will be present on both, but the Dexcom G7 will be approved for both the arm and the abdomen. The Dexcom also can communicate with several automated insulin delivery systems and data can be shared real-time with family members.
For clinicians just starting patients on this technology, my suggestion is to focus on one system so both the provider and staff can become familiar with it. It is key to review downloaded glucose metrics, in addition to the “ambulatory glucose profile,” a graphic overview of daily glycemia where patterns can be identified. It is also helpful to ask for assistance from endocrinologists who have experience with CGMs, in addition to the representatives of the companies.
COVID-19 and new-onset diabetes
From the beginning of the COVID 19 pandemic in 2020, it was clear that stress hyperglycemia and glucose dysregulation was an important observation for those infected. What was not known at the time is that for some, the hyperglycemia continued, and permanent diabetes ensued.
In one study of over 2.7 million U.S. veterans, men infected with COVID-19, but not women, were at a higher risk of new incident diabetes at 120 days after infection compared to no infection (odds ratio for men = 2.56).6
Another literature review using meta-analyses and cross-sectional studies concluded new-onset diabetes following COVID-19 infection can have a varied phenotype, with no risk factors, presenting from diabetic ketoacidosis to milder forms of diabetes.7
The current thought is that COVID-19 binds to the ACE2 and TMPRSS2 receptors which appear to be located on the beta-cells in the islet, resulting in insulin deficiency, in addition to the insulin resistance that seems to persist after the acute infection. Much more needs to be learned about this, but clinicians need to appreciate this appears to be a new form of diabetes and optimal treatments are not yet clear.

glucagonlike peptide-1 receptor agonists (GLP1RAs) and continuous glucose monitoring (CGM) technology. I am hoping my discussion about these major advances in this edition of Highlights will be helpful to those caring for patients with diabetes.
Tirzepatide
The first GLP1RA, exenatide, was released in April 2005. Since then, numerous daily and weekly drugs of this class have been developed. We’ve learned they are effective glucose lowering drugs, and the weekly agents dulaglutide and semaglutide have shown impressive weight reduction properties as well as cardiovascular benefits.
Secondary outcomes have also shown renal benefits to these agents, and studies for primary renal efficacy are pending. Due to all of these properties, the GLP1RAs are recommended as the first injectable for the treatment of type 2 diabetes, prior to insulin initiation.1
The next generation of these agents are a combination of a GLP1RA and a glucose-dependent insulinotropic polypeptide (GIP). Glucagonlike peptide-1 (GLP-1) stimulates insulin secretion, inhibits glucagon secretion, delays gastric emptying, and has central effects inducing satiety.
We now understand that GIP is the main incretin hormone in those without diabetes, causative of most of the incretin effects. But the insulin response after GIP secretion in type 2 diabetes is strongly reduced. It is now appreciated that this poor effect of GIP can be reduced when used in combination with a GLP1RA. This combination incretin, called by some a “twincretin,” is the basis for the drug tirzepatide which was approved by the Food and Drug Administration in May of 2022.
The data supporting this agent for both diabetes and obesity are impressive. For example, in a 40-week study with a baseline HbA1c of 8.0%, those randomized to tirzepatide at 5 mg, 10 mg, and 15 mg had HbA1c reductions of 1.87%, 1.89%, and 2.07% respectively.2 Over 81% at all doses had HbA1c levels less than 6.5% at 40 weeks.
For the 5-mg, 10-mg, and 15-mg doses, weight change from baseline was 7.9%, 9.3%, and 11.0% respectively. Like older GLP1RAs, gastrointestinal side effects were the main problem. For the three doses, 3%, 5%, and 7%, respectively, had to stop the drug, compared with the 3% who stopped taking the placebo. In another study, tirzepatide was noninferior or superior at all three doses compared with semaglutide 1 mg weekly.3
In a population without diabetes, with 40% of patients having prediabetes, weight loss percentages for the three doses were 15.0%, 19.5%, and 20.9% respectively.4 Discontinuation percentages due to side effects were 4%-7%. The exciting part is we now have a drug that approaches weight loss from bariatric surgery. The cardiovascular and renal outcome trials are now underway, but the enthusiasm for this drug is clear from the data.
Like other GLP1RAs, the key is to start low and go slowly. It is recommended to start tirzepatide at 2.5 mg four times a week, then increase to 5 mg. Due to gastrointestinal side effects, some patients will do better at the lower dose before increasing. For those switching from another GLP1RA, there are no data to guide us but, in my practice, I start those patients at 5 mg weekly.
Continuous glucose monitoring
Data continue to accumulate that this form of glycemic self-monitoring is effective to reduce HbA1c levels and minimize hypoglycemia in both type 1 and type 2 diabetes. The most important change to the 2022 American Diabetes Association (ADA) standards of care is recognizing CGM as level A evidence for those receiving basal insulin without mealtime insulin.5 There are four CGMs on the market, but most of the market uses the Dexcom G6 or the Libre 2. Both of these devices will be updated within the next few months to newer generation sensors.
While there are similarities and differences between the two devices, by late 2022 and early 2023 changes to both will reduce the dissimilarities.
The next generation Libre (Libre 3) will be continuous, and “scanning” will no longer be required. For those unable to get insurance to cover CGM, the Libre will continue to be more affordable than the Dexcom. Alerts will be present on both, but the Dexcom G7 will be approved for both the arm and the abdomen. The Dexcom also can communicate with several automated insulin delivery systems and data can be shared real-time with family members.
For clinicians just starting patients on this technology, my suggestion is to focus on one system so both the provider and staff can become familiar with it. It is key to review downloaded glucose metrics, in addition to the “ambulatory glucose profile,” a graphic overview of daily glycemia where patterns can be identified. It is also helpful to ask for assistance from endocrinologists who have experience with CGMs, in addition to the representatives of the companies.
COVID-19 and new-onset diabetes
From the beginning of the COVID 19 pandemic in 2020, it was clear that stress hyperglycemia and glucose dysregulation was an important observation for those infected. What was not known at the time is that for some, the hyperglycemia continued, and permanent diabetes ensued.
In one study of over 2.7 million U.S. veterans, men infected with COVID-19, but not women, were at a higher risk of new incident diabetes at 120 days after infection compared to no infection (odds ratio for men = 2.56).6
Another literature review using meta-analyses and cross-sectional studies concluded new-onset diabetes following COVID-19 infection can have a varied phenotype, with no risk factors, presenting from diabetic ketoacidosis to milder forms of diabetes.7
The current thought is that COVID-19 binds to the ACE2 and TMPRSS2 receptors which appear to be located on the beta-cells in the islet, resulting in insulin deficiency, in addition to the insulin resistance that seems to persist after the acute infection. Much more needs to be learned about this, but clinicians need to appreciate this appears to be a new form of diabetes and optimal treatments are not yet clear.

Poor physician access linked with unplanned return ED visits
Difficulty in accessing a family physician is associated with a higher risk for unplanned return visits to the emergency department among patients aged 75 years and older, new data indicate.
In a prospective, observational study that included almost 2,000 patients in this age group, 16% of participants attempted to contact their family physicians before their ED visits. Of this group, more than half reported having difficulty seeing their physicians for urgent problems, more than 40% had difficulty speaking with their family physicians by telephone, and more than one-third had difficulty booking appointments for new health problems.
write study author Marc Afilalo, MD, director of the ED at Jewish General Hospital in Montreal, and colleagues. “Therefore, community-based programs that target patient education and improved access to primary care are necessary not only for reducing return visits to the ED, but also for continuity of care and patient satisfaction.”
The study was published in Canadian Family Physician.
Comorbidities increased risk
Researchers have estimated that half of Canadians aged 75 years or older use emergency services. Data indicate that the number of unplanned return visits to the ED is associated with increased functional decline and death. But the question of how patient access to primary care services affects unplanned ED return visits has received little attention, according to the investigators.
They conducted a multicenter study at three tertiary adult teaching hospitals in Montreal. From 2012 to 2014, they recruited patients aged 75 years and older who had visited the ED and who lived in their own homes or in an autonomous residence.
Investigators collected data through structured interviews, administrative databases, and medical chart reviews. They followed up with participants at 3 months by telephone. The study’s main outcome was return visit to the ED.
The researchers identified 4,577 patients and included 1,998 in their analysis. Of that total, 33% were 85 or older, 34% lived alone, and 91% had a family physician. Within 3 months, 562 patients (28%) had made 894 return visits to the ED.
Among patients aged 85 years or older (relative risk, 0.80), as well as those whose triage score was less severe (RR, 0.83) and those who were admitted during the index ED visit (RR, 0.76), rates of return ED visits were lower. Among patients who had trouble booking appointments with their family doctors to address new problems (RR, 1.19), as well as those who had made ED visits within the previous 6 months (RR, 1.47) or had a higher Charlson comorbidity index score (RR, 1.06 for every 1-unit increase), rates of return visits were higher.
Factors associated with a higher likelihood of return visits were visits to the ED in the previous 6 months (odds ratio, 2.11), increased Charlson comorbidity index score (OR, 1.41 for every 1-unit increase), and having received help from local community services (OR, 3.00).
Primary care access
The study suggests that improvements in primary care access are needed to decrease return visits to the ED, Samir Sinha, MD, DPhil, director of geriatrics at Mount Sinai and the University Health Network Hospitals in Toronto, told this news organization. Dr. Sinha was not involved in the study.
“It reminds us of the importance of having a strong primary care system,” he added. “Of this population, 91% had primary care providers. And what the paper demonstrates is that those who are having trouble accessing their primary care providers are more likely to be readmitted to an ED. We can only imagine how much worse the outcomes are for people who don’t have a primary care provider.”
Patients are frequently advised to visit the ED when they contact their primary care providers, said Mark Rosenberg, PhD, professor of geography and planning and the Canada Research Chair in Aging, Health, and Development at Queens University in Kingston, Ont., said in an interview. He noted that primary care is organized as an appointment-based system. Dr. Rosenberg did not participate in the study.
“If I were to call my primary care provider in the middle of the afternoon and say that I have got chest pains, they are going to simply tell me to go to emergency,” said Dr. Rosenberg. “It is not just older people. Many people end up in the ED because they are told to go to the ED.”
Associations with age
“The higher your Charlson comorbidity index, the more multiple, complex health issues you’re dealing with,” said Sinha. He added that the data suggest the frailty of the study population.
The association between age 85 years or older and a lower rate of a return ED visits might mean that the patient did not return to independent living after the ED visit, Dr. Rosenberg speculated. “If it’s a serious health problem, you’re more likely to end up going into long-term care at that stage, and you are not going back to living in the community in your home,” he said. “You’re likely going into some sort of transition care or alternative care.”
People aged 85 years or older who are hospitalized are more likely not to survive their index hospital admission, compared with patients who are aged 75-85 years. There would be no possibility that such patients would revisit the ED in the future, said Dr. Sinha.
Expanding primary care
The major solution to decreasing reliance on the ED lies in revamping primary health care so that it offers an expanded level of care and 24/7 access, said Dr. Rosenberg.
Providing continuity of care, identifying problems, and managing them in the community before they become urgent or require a hospitalization are priorities for primary care and will help shift away from return visits to the ED, which should be a last resort for patients, said Dr. Sinha.
Moreover, patients must be able to access primary care in various ways, be it a telephone consultation, a video consultation, or a face-to-face consultation, he added. Face-to-face consultations can take place in a provider’s office or even in a patient’s home when warranted, he said. “What we need to make sure of is that all three types of consultations are available, so that people can actually get the most appropriate care at the time they’re calling.”
The study had no external funding. Dr. Afilalo, Dr. Sinha, and Dr. Rosenberg have disclosed no relevant financial relationships.

FROM CANADIAN FAMILY PHYSICIAN
Is it COVID or long COVID? Your organs may know
There’s little doubt long COVID is real. The federal government recognizes long COVID as a condition and said in two reports issued in August that one in five adult COVID-19 survivors have a health condition related to their illness.
COVID-19 can damage multiple organs in the body. Sometimes this damage leads to long COVID; sometimes other reasons are at play. Doctors are beginning to sort it out.
“COVID itself can actually cause prolonged illness, and we don’t really call that long COVID,” said Nisha Viswanathan, MD, a doctor at UCLA Health in Los Angeles. But if symptoms extend beyond 12 weeks, that puts patients in the realm of long COVID.
Symptoms can range from mild to severe and can keep people from resuming their normal lives and jobs. Sometimes they last for months, according to the U.S. Department of Health & Human Services.
Multiorgan damage
Lung scarring and other lung problems are common after COVID, said Leora Horwitz, MD, an internal medicine specialist at New York University. Even after a mild case, people can have breathing issues for months, a team at Johns Hopkins Medicine, Baltimore, said in an online briefing. One study published in the journal Radiology found damage in people a full year after a COVID-19 diagnosis.
Some people have persistent heart, kidney, liver, and nervous system problems after COVID-19. A study published in 2020 in JAMA Cardiology found 60% of people who had COVID-19 had ongoing signs of heart inflammation. Nearly a third of people hospitalized for COVID-19 get kidney damage that can become chronic, and some end up needing dialysis or a transplant, said C. John Sperati, MD, a kidney specialist at Johns Hopkins Medicine.
This might be, in part, because SARS-CoV-2, the virus that causes COVID-19, directly infects the cells in many organs.
Nicole Bhave, MD, a cardiologist at University of Michigan Health, Ann Arbor is concerned that COVID-19 appears to increase the risk of heart problems in some people.
“Some of the uptick may just be recognition bias, in that people with symptoms are seeking care,” she said. “But there’s definitely a biological basis by which COVID could tip people over into a new diagnosis of heart failure.”
Inflammation
Inflammation is probably a key part of the long-term effects of COVID-19.
Some people have a serious immune reaction to COVID-19 called a cytokine storm, said Nitra Aggarwal Gilotra, MD, a cardiologist at Johns Hopkins Medicine. This release of inflammation-causing molecules called cytokines is meant to attack the invading virus. But it can be so severe that it wreaks havoc on healthy tissues and organs and causes lasting damage – if patients even survive it.
In some people, inflammation can affect the heart, causing myocarditis. Myocarditis symptoms include chest pain, breathlessness, and heart palpitations. Though rare, it can be serious and can raise the risk of other heart problems, including heart failure, down the line.
Long COVID may also trigger an autoimmune condition, said Eline Luning Prak, MD, PhD, a pathologist at the Hospital of the University of Pennsylvania, Philadelphia. Long COVID can share many hallmark symptoms with autoimmune diseases, including fatigue, widespread pain, memory problems, and mood disorders.
Blood clots
Studies have shown the overcharged inflammatory response to COVID-19 can cause blood clots. This sometimes overwhelming clotting was an early hallmark of COVID-19 infection, and when clots restrict blood flow in the brain, lungs, kidneys, or limbs, they can cause long-term damage. Some can be deadly. Researchers in Sweden found patients were at risk of deep vein thrombosis – a blood clot usually in the leg – up to 3 months after infection and at higher risk of a blood clot in the lung, called pulmonary embolism, for as long as 3 months.
Viral reservoirs
The virus itself may also linger in a patient’s body, causing continued symptoms and, potentially, new flare-ups. Zoe Swank, PhD, of Harvard Medical School, Boston, and colleagues reported in a preprint study that they found pieces of the SARS-CoV-2 virus in the blood of most patients with long COVID symptoms they tested – some as long as a year after infection. The study has not yet been peer reviewed.
Another team found evidence of the virus in stool up to 7 months later, which suggests the virus hides out in the gut. Other early studies have found bits of viral RNA in the appendix, breast tissue, heart, eyes, and brain.
Diabetes
Diabetes is a risk factor for getting severe COVID-19, and multiple studies have shown people can get diabetes both while battling infection and afterward. One study of veterans, published in The Lancet Diabetes and Endocrinology, found COVID-19 survivors were about 40% more likely to get diabetes over the next year.
There are a few ways this might happen. Insulin-producing cells in the pancreas have SARS-CoV-2 receptors – a type of molecular doorway the coronavirus can attach to. Damage to these cells could make the body less able to produce insulin, which in turn can lead to diabetes. The virus could also disrupt the balance in the body or cause inflammation that leads to insulin resistance, which can develop into diabetes, Ziad Al-Aly, MD, of the Veterans Affairs St. Louis Health Care System, and colleagues wrote.
Nervous system issues
People who get COVID-19 are also more vulnerable to postural orthostatic tachycardia syndrome (POTS). This affects what’s known as the autonomic nervous system, which regulates blood circulation, and includes those things that happen in your body without your having to think about them, like breathing, heartbeat, and digestion. POTS can cause common long COVID neurologic symptoms, including headaches, fatigue, brain fog, insomnia, and problems thinking and concentrating. “This was a known condition prior to COVID, but it was incredibly rare,” said Dr. Viswanathan. “After COVID, I’ve seen it with increasing frequency.”
Long-term outlook
Lasting issues after COVID-19 are much more likely after a moderate or severe infection. Still, plenty of people are battling them even after a mild illness. “As for why, that’s the billion-dollar question,” said Dr. Horwitz. “It’s well known that viral infections can cause long-term dysregulation. Why that is, we really just don’t know.”
Whether it’s virus hiding out in the body, long-term organ damage, or an autoimmune reaction likely differs from person to person. “I’m believing, increasingly, that it’s a combination of all of these, just based on how different patients are responding to different medications,” said Dr. Viswanathan. “One patient will respond to something beautifully, and another patient won’t at all.”
But it’s clear a significant number of people are facing long-term health struggles because of COVID-19, which has infected at least 580 million people globally and 92 million – likely many more – in the United States, according to Johns Hopkins University.
Even a small increased risk of conditions like heart disease or diabetes translates to a huge number of people, Dr. Horwitz said. “If even 1% of people getting COVID have long-term symptoms, that’s a major public health crisis, because that’s 1% of pretty much everybody in the country.”

There’s little doubt long COVID is real. The federal government recognizes long COVID as a condition and said in two reports issued in August that one in five adult COVID-19 survivors have a health condition related to their illness.
COVID-19 can damage multiple organs in the body. Sometimes this damage leads to long COVID; sometimes other reasons are at play. Doctors are beginning to sort it out.
“COVID itself can actually cause prolonged illness, and we don’t really call that long COVID,” said Nisha Viswanathan, MD, a doctor at UCLA Health in Los Angeles. But if symptoms extend beyond 12 weeks, that puts patients in the realm of long COVID.
Symptoms can range from mild to severe and can keep people from resuming their normal lives and jobs. Sometimes they last for months, according to the U.S. Department of Health & Human Services.
Multiorgan damage
Lung scarring and other lung problems are common after COVID, said Leora Horwitz, MD, an internal medicine specialist at New York University. Even after a mild case, people can have breathing issues for months, a team at Johns Hopkins Medicine, Baltimore, said in an online briefing. One study published in the journal Radiology found damage in people a full year after a COVID-19 diagnosis.
Some people have persistent heart, kidney, liver, and nervous system problems after COVID-19. A study published in 2020 in JAMA Cardiology found 60% of people who had COVID-19 had ongoing signs of heart inflammation. Nearly a third of people hospitalized for COVID-19 get kidney damage that can become chronic, and some end up needing dialysis or a transplant, said C. John Sperati, MD, a kidney specialist at Johns Hopkins Medicine.
This might be, in part, because SARS-CoV-2, the virus that causes COVID-19, directly infects the cells in many organs.
Nicole Bhave, MD, a cardiologist at University of Michigan Health, Ann Arbor is concerned that COVID-19 appears to increase the risk of heart problems in some people.
“Some of the uptick may just be recognition bias, in that people with symptoms are seeking care,” she said. “But there’s definitely a biological basis by which COVID could tip people over into a new diagnosis of heart failure.”
Inflammation
Inflammation is probably a key part of the long-term effects of COVID-19.
Some people have a serious immune reaction to COVID-19 called a cytokine storm, said Nitra Aggarwal Gilotra, MD, a cardiologist at Johns Hopkins Medicine. This release of inflammation-causing molecules called cytokines is meant to attack the invading virus. But it can be so severe that it wreaks havoc on healthy tissues and organs and causes lasting damage – if patients even survive it.
In some people, inflammation can affect the heart, causing myocarditis. Myocarditis symptoms include chest pain, breathlessness, and heart palpitations. Though rare, it can be serious and can raise the risk of other heart problems, including heart failure, down the line.
Long COVID may also trigger an autoimmune condition, said Eline Luning Prak, MD, PhD, a pathologist at the Hospital of the University of Pennsylvania, Philadelphia. Long COVID can share many hallmark symptoms with autoimmune diseases, including fatigue, widespread pain, memory problems, and mood disorders.
Blood clots
Studies have shown the overcharged inflammatory response to COVID-19 can cause blood clots. This sometimes overwhelming clotting was an early hallmark of COVID-19 infection, and when clots restrict blood flow in the brain, lungs, kidneys, or limbs, they can cause long-term damage. Some can be deadly. Researchers in Sweden found patients were at risk of deep vein thrombosis – a blood clot usually in the leg – up to 3 months after infection and at higher risk of a blood clot in the lung, called pulmonary embolism, for as long as 3 months.
Viral reservoirs
The virus itself may also linger in a patient’s body, causing continued symptoms and, potentially, new flare-ups. Zoe Swank, PhD, of Harvard Medical School, Boston, and colleagues reported in a preprint study that they found pieces of the SARS-CoV-2 virus in the blood of most patients with long COVID symptoms they tested – some as long as a year after infection. The study has not yet been peer reviewed.
Another team found evidence of the virus in stool up to 7 months later, which suggests the virus hides out in the gut. Other early studies have found bits of viral RNA in the appendix, breast tissue, heart, eyes, and brain.
Diabetes
Diabetes is a risk factor for getting severe COVID-19, and multiple studies have shown people can get diabetes both while battling infection and afterward. One study of veterans, published in The Lancet Diabetes and Endocrinology, found COVID-19 survivors were about 40% more likely to get diabetes over the next year.
There are a few ways this might happen. Insulin-producing cells in the pancreas have SARS-CoV-2 receptors – a type of molecular doorway the coronavirus can attach to. Damage to these cells could make the body less able to produce insulin, which in turn can lead to diabetes. The virus could also disrupt the balance in the body or cause inflammation that leads to insulin resistance, which can develop into diabetes, Ziad Al-Aly, MD, of the Veterans Affairs St. Louis Health Care System, and colleagues wrote.
Nervous system issues
People who get COVID-19 are also more vulnerable to postural orthostatic tachycardia syndrome (POTS). This affects what’s known as the autonomic nervous system, which regulates blood circulation, and includes those things that happen in your body without your having to think about them, like breathing, heartbeat, and digestion. POTS can cause common long COVID neurologic symptoms, including headaches, fatigue, brain fog, insomnia, and problems thinking and concentrating. “This was a known condition prior to COVID, but it was incredibly rare,” said Dr. Viswanathan. “After COVID, I’ve seen it with increasing frequency.”
Long-term outlook
Lasting issues after COVID-19 are much more likely after a moderate or severe infection. Still, plenty of people are battling them even after a mild illness. “As for why, that’s the billion-dollar question,” said Dr. Horwitz. “It’s well known that viral infections can cause long-term dysregulation. Why that is, we really just don’t know.”
Whether it’s virus hiding out in the body, long-term organ damage, or an autoimmune reaction likely differs from person to person. “I’m believing, increasingly, that it’s a combination of all of these, just based on how different patients are responding to different medications,” said Dr. Viswanathan. “One patient will respond to something beautifully, and another patient won’t at all.”

Most people with Omicron don’t know they’re infected
Most people with Omicron likely don’t know it.
That’s according to a study in JAMA Network Open, which says 56% of people who have the Omicron variant of the coronavirus are unaware of their infection.
And it has an upside and a downside, depending on how you look at it, according to Time magazine.
“It’s good news, in some ways, since ) in vaccinated people,” Time says. “The downside is that many people are likely spreading the virus unintentionally.”
The study looked at 210 hospital patients and employees in the Los Angeles area. More than half who tested positive didn’t know it – because they had no symptoms, or they assumed they merely had a cold or allergies.
“The findings support early data from around the world suggesting that throughout the pandemic, anywhere from 25% to 40% of SARS-CoV-2 infections have been asymptomatic, which presents challenges for public health officials trying to control the spread of the virus,” Time reports.
The study found that awareness of infection rose after at-home tests became available this year. About three-quarters of people in January and February didn’t know their status, for example.
“Findings of this study suggest that low rates of Omicron variant infection awareness may be a key contributor to rapid transmission of the virus within communities,” the authors wrote. “Given that unawareness of active infection precludes self-initiated interventions, such as testing and self-isolation, even modest levels of undiagnosed infection can contribute to substantial population-level transmission.”
