COVID-19 causes DNA damage to the heart, affecting the body in a completely different way than the flu does, according to a study published in Immunology. 

The study looked at the hearts of patients who died from COVID-19, the flu, and other causes. The findings could provide clues about why coronavirus has led to complications such as ongoing heart issues.

“We found a lot of DNA damage that was unique to the COVID-19 patients, which wasn’t present in the flu patients,” Arutha Kulasinghe, one of the lead study authors and a research fellow at the University of Queensland, Brisbane, Australia, told the Brisbane Times.

“So in this study, COVID-19 and flu look very different in the way they affect the heart,” he said.

Dr. Kulasinghe and colleagues analyzed the hearts of seven COVID-19 patients, two flu patients, and six patients who died from other causes. They used transcriptomic profiling, which looks at the DNA landscape of an organ, to investigate heart tissue from the patients.

Because of previous studies about heart problems associated with COVID-19, he and colleagues expected to find extreme inflammation in the heart. Instead, they found that inflammation signals had been suppressed in the heart, and markers for DNA damage and repair were much higher. They’re still unsure of the underlying cause.

“The indications here are that there’s DNA damage here, it’s not inflammation,” Dr. Kulasinghe said. “There’s something else going on that we need to figure out.”

The damage was similar to the way chronic diseases such as diabetes and cancer appear in the heart, he said, with heart tissue showing DNA damage signals. 

Dr. Kulasinghe said he hopes other studies can build on the findings to develop risk models to understand which patients may face a higher risk of serious COVID-19 complications. In turn, this could help doctors provide early treatment. For instance, all seven COVID-19 patients had other chronic diseases, such as diabetes, hypertension, and heart disease. 

“Ideally in the future, if you have cardiovascular disease, if you’re obese or have other complications, and you’ve got a signature in your blood that indicates you are at risk of severe disease, then we can risk-stratify patients when they are diagnosed,” he said. 

The research is a preliminary step, Dr. Kulasinghe said, because of the small sample size. This type of study is often difficult to conduct because researchers have to wait for the availability of organs, as well as request permission from families for postmortem autopsies and biopsies, to be able to look at the effects on dead tissues.

“Our challenge now is to draw a clinical finding from this, which we can’t at this stage,” he added. “But it’s a really fundamental biological difference we’re observing [between COVID-19 and flu], which we need to validate with larger studies.”

The Asia-Pacific Colorectal Screening (APCS) scoring system, combined with a stool DNA test, could improve the detection of advanced colorectal neoplasms and limit colonoscopy use, according to a new study published in Clinical Gastroenterology and Hepatology.

Although a colonoscopy can detect both colorectal cancer and precancerous lesions, using it as the primary screening tool can cause barriers due to high costs, limited resources, and low compliance, wrote Junfeng Xu of the gastroenterology department at the First Medical Center of Chinese PLA General Hospital, Beijing, and colleagues.

Avoiding complications

“Colonoscopy is expensive and time consuming for both the patient and the health care system. Colonoscopy is also not without risk since bowel perforation, post-procedural bleeding, and sedation-related complications all occur at low but measurable rates,” said Reid Ness, MD, associate professor of medicine and gastroenterologist at Vanderbilt University Medical Center, Nashville, Tenn.

“The primary strength of the study was that all patients eventually received colonoscopy, allowing for the best estimate of strategy sensitivity for advanced colorectal neoplasia,” he said.

At the same time, the cross-sectional study was unable to estimate the benefit of using this type of screening strategy over time, Dr. Ness said. With limited endoscopic resources available in many countries, however, clinicians need better modalities and strategies for noninvasive identification of advanced colorectal neoplasia, he added.

“Since less than 5% of the population will eventually develop colorectal cancer, the overwhelming majority can only be discomfited and possibly injured through colonoscopy screening,” he said. “For these reasons, the use of a CRC screening strategy that minimizes the use of colonoscopy without compromising the identification rate for advanced colorectal neoplasia is best for both the patient and the health care system.”

The study was supported by grants from the Beijing Municipal Science and Technology Commission. The authors declared no conflicts of interest. Dr. Ness reported no relevant disclosures.

The diagnosis and management of refractory celiac disease remains challenging, but ongoing studies can provide the proper diagnostic criteria and identify the optimal management strategies, according to a new American Gastroenterological Association expert review published in Gastroenterology.

Celiac disease is present in about 1% of the U.S. population and can cause various symptoms, wrote Peter H. R. Green, MD, director of the Celiac Disease Center at Columbia University, New York, and colleagues. Adhering to a strict gluten-free diet can improve symptoms, normalize serum antibody levels, and reverse small bowel villous atrophy. However, persistent or recurrent symptoms and elevated celiac antibodies can persist in some patients after a year of trying a gluten-free diet, a condition called nonresponsive celiac disease. In some patients, this raises concern for refractory celiac disease, or RCD.

“RCD is believed to occur in only approximately 1% of patients with celiac disease, although this may be an overestimate, as data are obtained from referral centers,” the authors wrote.

RCD can be classified into two subtypes with different diagnostic criteria, prognoses, and therapy responses. The first, called RCD1, is characterized by villous atrophy but has intraepithelial lymphocytes similar to conventional celiac disease. The other, called RCD2, is characterized by aberrant clonal T-cell expansion in the intestinal tract and other organs, has a poorer prognosis than RCD1, and has a risk of developing ulcerative jejunoileitis or enteropathy-associated T-cell lymphoma.

The experts developed 10 clinical practice advice statements based on a review of the published literature and expert opinion.

First, in patients who have persistent or recurring symptoms, an initial celiac disease diagnosis should be confirmed through review of prior diagnostic testing, including serologies, endoscopies, and histologic findings. Celiac disease can overlap with other gastrointestinal conditions, and some pathologic findings aren’t specific to celiac disease. Results of serologic testing with tissue transglutaminase immunoglobulin A, deamidated gliadin peptide IgA and IgG, and endomysial antibodies should be reviewed or obtained if not previously performed.

Next, in those with confirmed but nonresponsive celiac disease, ongoing gluten ingestion should be excluded as a cause of symptoms with serologic testing, dietitian review, and potentially detection of immunogenic peptides in stool or urine samples. The authors noted that persistent gluten ingestion, whether intentional or inadvertent, accounts for 40%-50% of patients with nonresponsive celiac disease. In these cases, esophagogastroduodenoscopy and small bowel biopsies should be performed to look for persistent villous atrophy, which can also be caused by common variable immunodeficiency, autoimmune enteropathy, tropical sprue, and medication-induced enteropathy. Patients with villous atrophy due to other causes won’t respond to a gluten-free diet.

After excluding gluten, clinicians should perform a systematic evaluation for other potential causes of symptoms, including functional bowel disorders, lactose or fructose intolerance, microscopic colitis, pancreatic insufficiency, inflammatory bowel disease, and small intestinal bacterial growth. Irritable bowel syndrome, for instance, may contribute to persistent symptoms and respond to fermentable oligo-, di-, and monosaccharides and polyols (FODMAP) restriction. RCD should be strongly considered in patients with persistent symptoms or signs of malabsorption after the exclusion of the other causes.

To distinguish between the two subtypes of RCD and exclude enteropathy-associated T-cell lymphoma, clinicians should use flow cytometry, immunohistochemistry, and T-cell receptor rearrangement studies. RCD1 has a normal intraepithelial lymphocyte population, and RCD2 has an aberrant, clonal intraepithelial lymphocyte population. Consulting with a hematopathologist may be necessary to interpret these studies.

After RCD2 is diagnosed, complications such as enteropathy-associated T-cell lymphoma and ulcerative jejunoileitis should be excluded through small bowel imaging with capsule endoscopy and either computed tomography (CT) or magnetic resonance enterography. In general, the extent and severity of villous atrophy is greater in patients with RCD2, compared with RCD1.

In patients diagnosed with RCD, clinicians should complete a detailed nutritional assessment with investigation of micronutrient and macronutrient deficiencies. Check albumin as an independent prognostic factor. Then, try to correct deficiencies with oral supplements. Malnourished patients may need enteral support, and those with severe malnutrition due to malabsorption may need parenteral support.

So far, RCD management suggestions are based on small retrospective studies and expert opinion, with minimal prospective data and no Food and Drug Administration–approved therapies. The goals should be to improve symptoms and duodenal mucosal abnormalities, manage malnutrition, and prevent lymphoma. Glucocorticoids are considered first-line therapy, typically open-capsule budesonide given as 3 mg three times daily. Prednisone serves as an alternative with proven efficacy but a higher risk for adverse effects.

The optimal choice for second-line therapy is unknown, but the addition of an immunosuppressant agent to steroids appears to be effective in RCD1, including azathioprine, mercaptopurine, and tioguanine. The best treatment for RCD2 is unknown, though clinical response has been reported with steroids, and cladribine has been well tolerated in some patients.

Patients with RCD who don’t respond to steroids may benefit from referral to a center with expertise for management or evaluation for inclusion in clinical trials. Frequent medical visits are advised until the disease is well controlled, with regular follow-up after that. 

Ultimately, “patients with RCD benefit from evaluation and regular follow-up by a multidisciplinary team, including gastroenterologists and dietitians, to assess clinical and histologic response to therapy,” the authors wrote. “Identify local experts with expertise in celiac disease to assist with management.”

The authors reported no grant support or funding sources for this study. One author has received research report from Freenome, and another is on the celiac disease advisory board for Takeda. The remaining authors disclosed no conflicts.

The Safer Opioid Supply (SOS) Program near Toronto, Canada, appears to be a safe and effective harm-reduction initiative, according to new data.

An analysis indicates that the program is associated with a reduction in emergency department visits, hospitalizations, and overall health care costs. In addition, there were no opioid-related deaths among participants who were at high risk of overdose.

“Not only did hospital engagements decline immediately after starting SOS programs, but also the risk of overdose did not change, and there were no opioid-related deaths in the 1-year follow-up,” study author Tara Gomes, PhD, an assistant professor of health policy, management, and evaluation at the University of Toronto and a scientist at the Li Ka Shing Knowledge Institute of St. Michael’s Hospital in Toronto, said in an interview.

Dr. Gomes is the lead principal investigator of the Ontario Drug Policy Research Network, a collaboration between researchers and drug policy decision-makers in the province.

“These changes were not seen in a group of similar individuals who lived in the same city – so were exposed to the same illicit drug supply – but who were not part of this program, helping to reinforce that these changes are specific to SOS participation,” she said.

The study was published in the Canadian Medical Association Journal.
 

Hospital admissions declined

More than 29,000 opioid-related toxicity deaths occurred in Canada between 2016 and 2021, often as a result of high levels of fentanyl in the drug supply, according to the investigators. In response, SOS programs have been launched in several provinces, including the first formal SOS program at the London (Ont.) InterCommunity Health Centre. As part of the program, clients are prescribed pharmaceutical opioids as an alternative to the fentanyl-adulterated drug supply and are given health and social supports.

Dr. Gomes and colleagues conducted an interrupted time series analysis of residents in London, Ont., who had received a diagnosis of opioid use disorder and had had a health care encounter related to the diagnosis between January 2016 and March 2019. They followed 82 participants who entered the SOS program, as well as a comparison group of 303 people who were matched on the basis of demographic and clinical characteristics but who did not participate in the program.

The research team focused on the population’s numbers of emergency department visits, hospital admissions, infection rates, and health care costs. They used autoregressive integrated moving average models to evaluate the effect of starting the SOS program and to compare the population’s outcome rates in the year before and after entering the program.

For participants who entered the program, the rate of emergency department visits declined by about 14 visits per 100 people. In addition, hospital admissions declined by about 5 admissions per 100 people. Health care costs that weren’t related to primary care or outpatient medications declined by about $922 per person. The rate of hospital admission for infections remained about the same; the investigators observed a decline of about 1.6 infections per 100 people.

In the year after entry into the program, emergency department visits, hospital admissions, infection-related admissions, and total health care costs declined significantly among SOS clients, compared with the year before.

Conversely, there were no significant changes in any of the measured outcomes among the 303 people who didn’t participate in the program.
 

Medication costs increased

DR. Gomes and colleagues noted that the findings provide preliminary evidence that SOS programs can play a role in the harm-reduction options available to those who are at high risk of drug poisoning and overdose. At the same time, many questions remain.

For instance, although total health care costs declined among those enrolled in the program, the medication-related costs increased. About 34% of participants had HIV, 69.5% had hepatitis C virus infection, and 28% had infectious complications in the year before entering the program. This finding may indicate that the participants had serious medical complications resulting from their drug use and were able to seek health care services.

“We interpret that to be a positive finding, because of the very high prevalence of HIV and hepatitis C in the SOS clients. Treatments for HIV and hepatitis C are lifesaving but expensive,” said Dr. Gomes. “Therefore, these higher medication costs are likely reflective of improved access to treatments for these infections, which can greatly improve people’s health and quality of life but also save the health care system money over the longer term.”

DR. Gomes and colleagues are now beginning to evaluate other SOS programs across Ontario. They hope to better understand the various approaches that are available and determine which models can best support people who face high risks because of drug use.
 

A limited solution?

Commenting on the study, Andrew Ivsins, PhD, a postdoctoral fellow in social medicine at the University of British Columbia in Vancouver and a research scientist at the British Columbia Centre on Substance Abuse, said, “This is an important study and one of the first to show how safe supply can help by building connections to the health care system that didn’t exist previously.”

Dr. Ivsins, who wasn’t involved with this study, has researched safe supply programs around Vancouver. He and colleagues found that among participants in these programs, the use of illicit street-purchased drugs decreased, which led to improved health and wellness.

“Safe supply is fundamentally, at the most basic level, a response to the highly toxic drug supply and out-of-control poisoning crisis in North America,” he said. “It’s a contentious issue, but it makes so much sense that, if what’s killing people is highly toxic drugs, we need to find a way to provide an option that doesn’t kill them.”

“Up to now, safer supply has mostly been used to reduce harms, including mortality and morbidity, in persons using illicit opioids. But if we really want to lower the risk linked to heavy contamination of the unregulated drug supply, safer supply programs will have to be extended to all substances potentially sold illegally,” Marie-Eve Goyer, MD, an assistant professor of family medicine at the University of Montreal, said in an interview.

Dr. Goyer, who wasn’t involved with this study, has conducted research about substance replacement therapy in Quebec. She found that many provinces are now reporting on new potent designer benzodiazepines that are being used or that are contaminating fentanyl, which calls for a broader approach to address the drug overdose crisis.

“Let’s realize that safer supply prescription is a very medicalized (and limited) solution to an epidemic that is made of stigma, criminalization, and repressive public policies,” she said. “Without true changes in the law, we will continue to see our people dying every day.”

The study was funded by grants from the Ontario Ministry of Health and the Canadian Institutes of Health Research. Dr. Gomes has received grants to support the research of both groups, and other authors have received support or fees related to the London InterCommunity Health Centre. Dr. Ivsins and Dr. Goyer have disclosed no relevant financial relationships.

The Safer Opioid Supply (SOS) Program near Toronto, Canada, appears to be a safe and effective harm-reduction initiative, according to new data.

An analysis indicates that the program is associated with a reduction in emergency department visits, hospitalizations, and overall health care costs. In addition, there were no opioid-related deaths among participants who were at high risk of overdose.

“Not only did hospital engagements decline immediately after starting SOS programs, but also the risk of overdose did not change, and there were no opioid-related deaths in the 1-year follow-up,” study author Tara Gomes, PhD, an assistant professor of health policy, management, and evaluation at the University of Toronto and a scientist at the Li Ka Shing Knowledge Institute of St. Michael’s Hospital in Toronto, said in an interview.

Dr. Gomes is the lead principal investigator of the Ontario Drug Policy Research Network, a collaboration between researchers and drug policy decision-makers in the province.

“These changes were not seen in a group of similar individuals who lived in the same city – so were exposed to the same illicit drug supply – but who were not part of this program, helping to reinforce that these changes are specific to SOS participation,” she said.

The study was published in the Canadian Medical Association Journal.
 

Hospital admissions declined

More than 29,000 opioid-related toxicity deaths occurred in Canada between 2016 and 2021, often as a result of high levels of fentanyl in the drug supply, according to the investigators. In response, SOS programs have been launched in several provinces, including the first formal SOS program at the London (Ont.) InterCommunity Health Centre. As part of the program, clients are prescribed pharmaceutical opioids as an alternative to the fentanyl-adulterated drug supply and are given health and social supports.

Dr. Gomes and colleagues conducted an interrupted time series analysis of residents in London, Ont., who had received a diagnosis of opioid use disorder and had had a health care encounter related to the diagnosis between January 2016 and March 2019. They followed 82 participants who entered the SOS program, as well as a comparison group of 303 people who were matched on the basis of demographic and clinical characteristics but who did not participate in the program.

The research team focused on the population’s numbers of emergency department visits, hospital admissions, infection rates, and health care costs. They used autoregressive integrated moving average models to evaluate the effect of starting the SOS program and to compare the population’s outcome rates in the year before and after entering the program.

For participants who entered the program, the rate of emergency department visits declined by about 14 visits per 100 people. In addition, hospital admissions declined by about 5 admissions per 100 people. Health care costs that weren’t related to primary care or outpatient medications declined by about $922 per person. The rate of hospital admission for infections remained about the same; the investigators observed a decline of about 1.6 infections per 100 people.

In the year after entry into the program, emergency department visits, hospital admissions, infection-related admissions, and total health care costs declined significantly among SOS clients, compared with the year before.

Conversely, there were no significant changes in any of the measured outcomes among the 303 people who didn’t participate in the program.
 

Medication costs increased

DR. Gomes and colleagues noted that the findings provide preliminary evidence that SOS programs can play a role in the harm-reduction options available to those who are at high risk of drug poisoning and overdose. At the same time, many questions remain.

For instance, although total health care costs declined among those enrolled in the program, the medication-related costs increased. About 34% of participants had HIV, 69.5% had hepatitis C virus infection, and 28% had infectious complications in the year before entering the program. This finding may indicate that the participants had serious medical complications resulting from their drug use and were able to seek health care services.

“We interpret that to be a positive finding, because of the very high prevalence of HIV and hepatitis C in the SOS clients. Treatments for HIV and hepatitis C are lifesaving but expensive,” said Dr. Gomes. “Therefore, these higher medication costs are likely reflective of improved access to treatments for these infections, which can greatly improve people’s health and quality of life but also save the health care system money over the longer term.”

The Food and Drug Administration has issued a warning against cooking chicken in NyQuil after a social media challenge that encouraged people to try it went viral.

Called the “sleepy chicken challenge,” the trend tells people to cook chicken in NyQuil or similar over-the-counter cough and cold medications, which include ingredients such as acetaminophen, dextromethorphan, and doxylamine.

“The challenge sounds silly and unappetizing – and it is. But it could also be very unsafe,” the FDA said. “Boiling a medication can make it much more concentrated and change its properties in other ways.”

Even if someone doesn’t plan to eat the chicken, inhaling the vapors of the medication while it cooks could cause high levels of the drug to enter the body.

“It could also hurt your lungs,” the FDA said. “Put simply: Someone could take a dangerously high amount of the cough and cold medicine without even realizing it.”

This isn’t the first time that social media challenges involving medicine have gone viral. In a 2020 TikTok challenge, people were encouraged to take large doses of the allergy medicine diphenhydramine, called the “Benadryl challenge,” to cause hallucinations. The FDA received several reports of teens who were hospitalized or died, and it issued a warning about taking high doses of the drug.

“These video challenges, which often target youths, can harm people – and even cause death,” the FDA said. “Nonprescription (also called over-the-counter or OTC) drugs are readily available in many homes, making these challenges even more risky.”

In the latest warning, the FDA provided several ways for parents to make it less likely for children to do the social media challenges, such as locking up prescription and over-the-counter medications to prevent accidental overdoses. The FDA also encouraged parents and guardians to have open conversations with their children.

“Sit down with your children and discuss the dangers of misusing drugs and how social media trends can lead to real, sometimes irreversible, damage,” the FDA said. “Remind your children that overdoses can occur with OTC drugs as well as with prescription drugs.”

Following the FDA warning, the American Academy of Pediatrics also issued an advisory about social media trends. Some challenges, such as the ALS ice bucket challenge or the mannequin challenge, can be fun and positive activities. But medication-related challenges, such as the sleepy chicken and Benadryl challenges, can cause serious heart problems, seizures, coma, and even death.

“Teens’ brains are still developing. The part of the brain that handles rational thought, the prefrontal cortex, is not fully developed until the mid-20s,” the American Academy of Pediatrics said. “This means teens are naturally more impulsive and likely to act before thinking through all of the ramifications.”

Social media rewards outrageous behavior, it wrote, and the more outrageous the behavior, the more likely someone will get more engagement online.

“It’s a quick moving, impulsive environment, and the fear of losing out is real for teens,” the academy said. “What they will focus on is that a popular kid in class did this and got hundreds of likes and comments.”

The academy suggested that parents and guardians talk with teens about which challenges are trending on social media and at school.

“Sometimes kids are more willing to talk about their peers than themselves,” it said. “Asking questions about school trends, friends and fads may yield more answers than direct questions about their own activities.”

More than 80% of U.S. maternal deaths across a 2-year period were due to preventable causes, according to a new CDC report.

Black mothers made up about a third of deaths, and more than 90% of deaths among Indigenous mothers were preventable.

“It’s significant. It’s staggering. It’s heartbreaking,” Allison Bryant, MD, a high-risk pregnancy specialist and senior medical director for health equity at Massachusetts General Hospital, told USA Today.

“It just means that we have so much work to do,” she said.

In the report, CDC researchers looked at pregnancy-related deaths between 2017 to 2019 based on numbers from maternal mortality review committees, which are multidisciplinary groups in 36 states that investigate the circumstances around maternal deaths.

Of the 1,018 deaths during the 2-year period, 839 occurred up to a year after delivery. About 22% of deaths happened during pregnancy, and 25% happened on the day of delivery or within a week after delivery. But 53% occurred more than 7 days after delivery.

Mental health conditions, such as overdoses and deaths by suicide, were the top underlying cause, followed by hemorrhage, or extreme bleeding. About a quarter of deaths were due to mental health conditions, followed by 14% due to hemorrhage and 13% due to heart problems. The rest were related to infection, embolism, cardiomyopathy, and high blood pressure-related disorders.

The analysis included a section on maternal deaths for American Indian and Alaska Native mothers, who are more than twice as likely as White mothers to die but are often undercounted in health data due to misclassification. More than 90% of their deaths were preventable between 2017 to 2019, with most due to mental health conditions and hemorrhage.

“It’s incredibly distressful,” Brian Thompson, MD, of the Oneida Nation and assistant professor of obstetrics and gynecology at Upstate Medical University, New York, told USA Today.

Dr. Thompson is working with the National Indian Health Board to create the first national tribal review committee for maternal deaths.

“It really needs to be looked at and examined why that is the case if essentially all of them are preventable,” he said.

Black mothers were also three times as likely as White mothers to die and more likely to die from heart problems. Hispanic mothers, who made up 14% of deaths, were more likely to die from mental health conditions.

Some of the deaths, such as hemorrhage, should be highly preventable. Existing toolkits for clinicians provide evidence-based guidelines to prevent and treat excessive bleeding.

“No pregnant person should be passing away from a hemorrhage,” Andrea Jackson, MD, division chief of obstetrics and gynecology at the University of California, San Francisco, told USA Today.

“We have the tools in the United States, and we know how to deal with it,” she said. “That was really disheartening to see.”

What’s more, the new CDC report highlights the need for more mental health resources during pregnancy and the postpartum period – up to a year or more after delivery – including improvements in access to care, diagnosis, and treatment.

“These are things that need to happen systemically,” LeThenia Baker, MD, an obstetrician and gynecologist at Wellstar Health, Georgia, told USA Today.

“It can’t just be a few practices here or there who are adopting best practices,” she said. “It has to be a systemic change.”

“It really needs to be looked at and examined why that is the case if essentially all of them are preventable,” he said.

Black mothers were also three times as likely as White mothers to die and more likely to die from heart problems. Hispanic mothers, who made up 14% of deaths, were more likely to die from mental health conditions.

Some of the deaths, such as hemorrhage, should be highly preventable. Existing toolkits for clinicians provide evidence-based guidelines to prevent and treat excessive bleeding.

“No pregnant person should be passing away from a hemorrhage,” Andrea Jackson, MD, division chief of obstetrics and gynecology at the University of California, San Francisco, told USA Today.

“We have the tools in the United States, and we know how to deal with it,” she said. “That was really disheartening to see.”

What’s more, the new CDC report highlights the need for more mental health resources during pregnancy and the postpartum period – up to a year or more after delivery – including improvements in access to care, diagnosis, and treatment.

“These are things that need to happen systemically,” LeThenia Baker, MD, an obstetrician and gynecologist at Wellstar Health, Georgia, told USA Today.

“It can’t just be a few practices here or there who are adopting best practices,” she said. “It has to be a systemic change.”

Several chiropractors in the United States are posting TikTok videos of themselves working with newborns, babies, and toddlers, often promoting treatments that aren’t backed by science, according to The Washington Post.

The videos include various devices and treatments, such as vibrating handheld massagers, spinal adjustments, and body movements, which are meant to address colic, constipation, reflux, musculoskeletal problems, and even trauma that babies experience during childbirth.

Chiropractors say the treatments are safe and gentle for babies and are unlike the more strenuous movements associated with adult chiropractic care. However, some doctors have said the videos are concerning because babies have softer bones and looser joints.

“Ultimately, there is no way you’re going to get an improvement in a newborn from a manipulation,” Sean Tabaie, MD, an orthopedic surgeon at Children’s National Hospital, Washington, told the newspaper.

Dr. Tabaie said his colleagues are shocked when he sends them Instagram or TikTok videos of chiropractic clinics treating infants.

“The only thing that you might possibly cause is harm,” he said.

Generally, chiropractors are licensed health professionals who use stretching, pressure, and joint manipulation on the spine to treat patients. Although chiropractic care is typically seen as an “alternative therapy,” some data in adults suggest that chiropractic treatments can help some conditions, such as low back pain.

“To my knowledge, there is little to no evidence that chiropractic care changes the natural history of any disease or condition,” Anthony Stans, MD, a pediatric orthopedic surgeon at Mayo Clinic Children’s Center, Rochester, Minn., told the newspaper. Stans said he would caution parents and recommend against chiropractic treatment for babies.

For some parents, the treatments and TikTok videos seem appealing because they promise relief for problems that traditional medicine can’t always address, especially colic, the newspaper reported. Colic, which features intense and prolonged crying in an otherwise healthy baby, tends to resolve over time without treatment.

Recent studies have attempted to study chiropractic care in infants. In a 2021 study, researchers in Denmark conducted a randomized controlled trial with 186 babies to test light pressure treatments. Although excessive crying was reduced by half an hour in the group that received treatment, the findings weren’t statistically significant in the end.

In a new study, researchers in Spain conducted a randomized trial with 58 babies to test “light touch manual therapy.” The babies who received treatment appeared to cry significantly less, but the parents weren’t “blinded” and were aware of the study’s treatment conditions, which can bias the results.

However, it can be challenging to “get that level of evidence” to support manual therapies such as chiropractic care, Joy Weydert, MD, director of pediatric integrative medicine at the University of Arizona, Tucson, told the newspaper. Certain treatments could help reduce the discomfort of colic or reflux, which can be difficult to measures in infants, she said.

The American Academy of Pediatrics told The Post that it doesn’t have an “official policy” on chiropractic care for infants or toddlers. At the same time, a 2017 report released by the organization concluded that “high-quality evidence” is lacking for spinal manipulation in children.

The American Chiropractic Association said chiropractic treatments are safe and effective for children, yet more research is needed to prove they work.

“We still haven’t been able to demonstrate in the research the effectiveness that we’ve seen clinically,” Jennifer Brocker, president of the group’s Council on Chiropractic Pediatrics, told the newspaper.

“We can’t really say for sure what’s happening,” she said. “It’s sort of like a black box. But what we do know is that, clinically, what we’re doing is effective because we see a change in the symptoms of the child.”

Warfarin is associated with higher rates of upper gastrointestinal bleeding but not overall or lower GI bleeding rates, compared with direct oral anticoagulants (DOACs), according to a new nationwide report from Iceland.

In addition, warfarin is associated with higher rates of major GI bleeding, compared with apixaban.

“Although there has been a myriad of studies comparing GI bleeding rates between warfarin and DOACs, very few studies have compared upper and lower GI bleeding rates specifically,” Arnar Ingason, MD, PhD, a gastroenterology resident at the University of Iceland and Landspitali University Hospital, Reykjavik, said in an interview.

“Knowing whether the risk of upper and lower GI bleeding differs between warfarin and DOACs is important, as it can help guide oral anticoagulant selection,” he said.

“Given that warfarin was associated with higher rates of upper GI bleeding compared to DOACs in our study, warfarin may not be optimal for patients with high risk of upper GI bleeding, such as patients with previous history of upper GI bleeding,” Dr. Ingason added.

The study was published online in Clinical Gastroenterology and Hepatology.
 

Analyzing bleed rates

Dr. Ingason and colleagues analyzed data from electronic medical records for more than 7,000 patients in Iceland who began a prescription for oral anticoagulants between 2014 and 2019. They used inverse probability weighting to yield balanced study groups and calculate the rates of overall, major, upper, and lower GI bleeding. All events of gastrointestinal bleeding were manually confirmed by chart review.

Clinically relevant GI bleeding was defined as bleeding that led to medical intervention, unscheduled physician contact, or temporary cessation of treatment. Upper GI bleeding was defined as hematemesis or a confirmed upper GI bleed site on endoscopy, whereas lower gastrointestinal bleeding was defined as hematochezia or a confirmed lower GI bleed site on endoscopy. Patients with melena and uncertain bleeding site on endoscopy were classified as having a gastrointestinal bleed of unknown location.

Major bleeding was defined as a drop in hemoglobin of at least 20 g/L, transfusion of two or more packs of red blood cells, or bleeding into a closed compartment such as the retroperitoneum.

In total, 295 gastrointestinal bleed events were identified, with 150 events (51%) classified as lower, 105 events (36%) classified as upper, and 40 events (14%) of an unknown location. About 71% required hospitalization, and 63% met the criteria for major bleeding. Five patients died, including three taking warfarin and the other two taking apixaban and rivaroxaban.

Overall, warfarin was associated with double the rate of upper GI bleeding, with 1.7 events per 100 person-years, compared with 0.8 events per 100 person-years for DOACs. The rates of lower GI bleeding were similar for the drugs.

Specifically, warfarin was associated with nearly 5.5 times higher rates of upper gastrointestinal bleeding, compared with dabigatran (Pradaxa, Boehringer Ingelheim), 2.6 times higher than apixaban (Eliquis, Bristol-Myers Squibb), and 1.7 times higher than rivaroxaban (Xarelto, Janssen). The risk for upper GI bleeding also was higher in men taking warfarin.

Warfarin was associated with higher rates of major bleeding, compared with apixaban, with 2.3 events per 100 person-years versus 1.5 events per 100 person-years. Otherwise, overall and major bleed rates were similar for users of warfarin and DOACs.

“GI bleeding among cardiac patients on anticoagulants and antiplatelets is the fastest growing group of GI bleeders,” Neena Abraham, MD, professor of medicine and a gastroenterologist at the Mayo Clinic in Scottsdale, Ariz., said in an interview.

Dr. Abraham, who wasn’t involved with this study, runs a dedicated cardiogastroenterology practice and has studied these patients’ bleeding risk for 20 years.

“This is a group that is ever increasing with aging baby boomers,” she said. “It is anticipated by 2040 that more than 40% of the U.S. adult population will have one or more cardiovascular conditions requiring the chronic prescription of anticoagulant or antiplatelet drugs.”
 

Considering future research

In this study, peptic ulcer disease was a proportionally less common cause of upper GI bleeding for warfarin at 18%, compared with DOACs at 39%. At the same time, the absolute propensity-weighted incidence rates of peptic ulcer–induced bleeding were similar, with 0.3 events per 100 person-years for both groups.

“As warfarin is not thought to induce peptic ulcer disease but rather promote bleeding from pre-existing lesions, one explanation may be that peptic ulcer disease almost always leads to overt bleeding in anticoagulated patients, while other lesions, such as mucosal erosions and angiodysplasias, may be more likely to lead to overt bleeding in warfarin patients due to a potentially more intense anticoagulation,” Dr. Ingason said.

Dr. Ingason and colleagues now plan to compare GI bleeding severity between warfarin and DOACs. Previous studies have suggested that GI bleeding may be more severe in patients receiving warfarin than in those receiving DOACs, he said.

In addition, large studies with manual verification of GI bleed events could better estimate the potential differences in the sources of upper and lower bleeding between warfarin and DOACs, Dr. Ingason noted.

“Some DOACs, specifically dabigatran, are known to have a mucosal effect on the luminal GI tract, as well as a systemic effect,” Dr. Abraham said. “This pharmacologic effect may contribute to an increase in lower gastrointestinal bleeding in the setting of colonic diverticulosis or mucosal injuries from inflammatory processes.”

Ongoing research should also look at different ways to reduce anticoagulant-related GI bleeding among cardiac patients, she noted.

“Our research group continues to study the risk of cardiac and bleeding adverse events in patients prescribed to DOACs compared to those patients who receive a left atrial appendage occlusion device,” Dr. Abraham said. “This device often permits patients at high risk of GI bleeding to transition off anticoagulant and antiplatelet drugs.”

The study was funded by the Icelandic Centre for Research and the Landspitali University Hospital Research Fund. The funders had no role in the design, conduct, or reporting of the study. The authors declared no competing interests. Dr. Abraham reported no relevant financial relationships.

Endoscopy plays an integral role in the evaluation and management of patients with recurrent acute pancreatitis and chronic pancreatitis, according to a new American Gastroenterological Association clinical practice update published in Gastroenterology.

Acute pancreatitis remains the leading cause of inpatient care among gastrointestinal conditions, with about 10%-30% of patients developing recurrent acute pancreatitis, wrote co–first authors Daniel Strand, MD, from the University of Virginia Health System, Charlottesville, and Ryan J. Law, MD, from the Mayo Clinic, Rochester, Minn., and colleagues. About 35% of patients with recurrent acute pancreatitis will progress to chronic pancreatitis. Both conditions are associated with significant morbidity and mortality.

“Interventions aimed to better evaluate, mitigate the progression of, and treat symptoms related to [acute pancreatitis] and [chronic pancreatitis] are critical to improve patients’ quality of life and other long-term outcomes,” the authors of the expert review wrote.

The authors reviewed randomized controlled trials, observational studies, systematic reviews and meta-analyses, and expert consensus in the field to develop eight clinical practice advice statements.

First, when the initial evaluation reveals no clear explanation for acute or recurrent pancreatitis, endoscopic ultrasound is the preferred diagnostic test. The authors noted that, although there isn’t a concretely defined optimal timing for EUS defined, most experts advise a short delay of 2-6 weeks after resolution of acute pancreatitis. MRI with contrast and cholangiopancreatography can be a reasonable complementary or alternative test, based on local expertise and availability.

Second, the role of ERCP remains controversial for reducing the frequency of acute pancreatitis episodes in patients with pancreas divisum, the most common congenital pancreatic anomaly, the authors wrote. However, minor papilla endotherapy may be useful, particularly for those with objective signs of outflow obstruction, such as a dilated dorsal pancreatic duct or santorinicele. However, there is no role for ERCP in treating pain alone in patients with pancreas divisum.

Third, ERCP remains even more controversial for reducing the frequency of pancreatitis episodes in patients with unexplained recurrent acute pancreatitis and standard pancreatic ductal anatomy, according to the authors. It should only be considered after a comprehensive discussion of the uncertain benefits and potentially severe procedure-related adverse events. When used, ERCP with biliary sphincterotomy alone may be preferable to dual sphincterotomy.

Fourth, for long-term treatment of patients with painful obstructive chronic pancreatitis, surgical intervention should be considered over endoscopic therapy, the study authors wrote. Pain is the most common symptom and important driver of impaired quality of life in patients with chronic pancreatitis, among whom a subset will be affected by intraductal hypertension from an obstructed pancreatic duct. The authors noted that endoscopic intervention remains a reasonable alternative to surgery for suboptimal operative candidates or patients who want a less-invasive approach, as long as they are clearly informed that the best practice advice primarily favors surgery.

Fifth, when using ERCP for pancreatic duct stones, small main pancreatic duct stones of 5 mm or less can be treated with pancreatography and conventional stone extraction maneuvers. For larger stones, however, extracorporeal shockwave lithotripsy or pancreatoscopy with intraductal lithotripsy can be considered, although the former is not widely available in the United States and the success rates for the latter vary.

Sixth, when using ERCP for pancreatic duct strictures, prolonged stent therapy for 6-12 months is effective for treating symptoms and remodeling main pancreatic duct strictures. The preferred approach is to place and sequentially add multiple plastic stents in parallel, or up-sizing. Emerging evidence suggests that fully covered self-expanding metal stents may be useful in this case, but additional research is needed. For example, one study suggested that patients treated with these self-expanding stents required fewer ERCPs, but their adverse event rate was significantly higher (39% vs. 14%).

Seventh, ERCP with stent insertion is the preferred treatment for benign biliary stricture caused by chronic pancreatitis. Fully covered self-expanding metal stents are favored over placing multiple plastic stents when feasible, given the similar efficacy but significantly lower need for stent exchange procedures during the treatment course.

Eighth, celiac plexus block shouldn’t be routinely performed for the management of pain caused by chronic pancreatitis. Celiac plexus block could be considered in certain patients on a case-by-case basis if they have debilitating pain that hasn’t responded to other therapeutic measures. However, this should only be considered after a discussion about the unclear outcomes and its procedural risks.

“Given the current lack of evidence, additional well-designed prospective comparative studies are needed to support a more unified diagnostic and therapeutic pathway for the treatment of these complex cases,” the authors concluded.

Endoscopy plays an integral role in the evaluation and management of patients with recurrent acute pancreatitis and chronic pancreatitis, according to a new American Gastroenterological Association clinical practice update published in Gastroenterology.

Acute pancreatitis remains the leading cause of inpatient care among gastrointestinal conditions, with about 10%-30% of patients developing recurrent acute pancreatitis, wrote co–first authors Daniel Strand, MD, from the University of Virginia Health System, Charlottesville, and Ryan J. Law, MD, from the Mayo Clinic, Rochester, Minn., and colleagues. About 35% of patients with recurrent acute pancreatitis will progress to chronic pancreatitis. Both conditions are associated with significant morbidity and mortality.

“Interventions aimed to better evaluate, mitigate the progression of, and treat symptoms related to [acute pancreatitis] and [chronic pancreatitis] are critical to improve patients’ quality of life and other long-term outcomes,” the authors of the expert review wrote.

The authors reviewed randomized controlled trials, observational studies, systematic reviews and meta-analyses, and expert consensus in the field to develop eight clinical practice advice statements.

First, when the initial evaluation reveals no clear explanation for acute or recurrent pancreatitis, endoscopic ultrasound is the preferred diagnostic test. The authors noted that, although there isn’t a concretely defined optimal timing for EUS defined, most experts advise a short delay of 2-6 weeks after resolution of acute pancreatitis. MRI with contrast and cholangiopancreatography can be a reasonable complementary or alternative test, based on local expertise and availability.

Second, the role of ERCP remains controversial for reducing the frequency of acute pancreatitis episodes in patients with pancreas divisum, the most common congenital pancreatic anomaly, the authors wrote. However, minor papilla endotherapy may be useful, particularly for those with objective signs of outflow obstruction, such as a dilated dorsal pancreatic duct or santorinicele. However, there is no role for ERCP in treating pain alone in patients with pancreas divisum.

Third, ERCP remains even more controversial for reducing the frequency of pancreatitis episodes in patients with unexplained recurrent acute pancreatitis and standard pancreatic ductal anatomy, according to the authors. It should only be considered after a comprehensive discussion of the uncertain benefits and potentially severe procedure-related adverse events. When used, ERCP with biliary sphincterotomy alone may be preferable to dual sphincterotomy.

Fourth, for long-term treatment of patients with painful obstructive chronic pancreatitis, surgical intervention should be considered over endoscopic therapy, the study authors wrote. Pain is the most common symptom and important driver of impaired quality of life in patients with chronic pancreatitis, among whom a subset will be affected by intraductal hypertension from an obstructed pancreatic duct. The authors noted that endoscopic intervention remains a reasonable alternative to surgery for suboptimal operative candidates or patients who want a less-invasive approach, as long as they are clearly informed that the best practice advice primarily favors surgery.

Fifth, when using ERCP for pancreatic duct stones, small main pancreatic duct stones of 5 mm or less can be treated with pancreatography and conventional stone extraction maneuvers. For larger stones, however, extracorporeal shockwave lithotripsy or pancreatoscopy with intraductal lithotripsy can be considered, although the former is not widely available in the United States and the success rates for the latter vary.

Sixth, when using ERCP for pancreatic duct strictures, prolonged stent therapy for 6-12 months is effective for treating symptoms and remodeling main pancreatic duct strictures. The preferred approach is to place and sequentially add multiple plastic stents in parallel, or up-sizing. Emerging evidence suggests that fully covered self-expanding metal stents may be useful in this case, but additional research is needed. For example, one study suggested that patients treated with these self-expanding stents required fewer ERCPs, but their adverse event rate was significantly higher (39% vs. 14%).

Seventh, ERCP with stent insertion is the preferred treatment for benign biliary stricture caused by chronic pancreatitis. Fully covered self-expanding metal stents are favored over placing multiple plastic stents when feasible, given the similar efficacy but significantly lower need for stent exchange procedures during the treatment course.

Eighth, celiac plexus block shouldn’t be routinely performed for the management of pain caused by chronic pancreatitis. Celiac plexus block could be considered in certain patients on a case-by-case basis if they have debilitating pain that hasn’t responded to other therapeutic measures. However, this should only be considered after a discussion about the unclear outcomes and its procedural risks.

Life expectancy in the United States declined again in 2021, after a historic drop in 2020, to reach the lowest point in decades, according to new CDC data.

In 2021, the average American could expect to live until age 76, which fell from 77 in 2020 and 79 in 2019. That marks the lowest age since 1996 and the largest 2-year decline since 1923.

“Even small declines in life expectancy of a tenth or two-tenths of a year mean that on a population level, a lot more people are dying prematurely,” Robert Anderson, PhD, chief of mortality statistics at the National Center for Health Statistics, which produced the report, told The New York Times.

“This signals a huge impact on the population in terms of increased mortality,” he said.

COVID-19 played a major role, with excess death from the coronavirus contributing to half of the decline during the past 2 years. Drug overdose deaths also reached a record high in 2021, rising to about 109,000 people. Unintentional injuries, with about half due to drug overdose, were a leading cause of the decline in life expectancy, along with deaths from heart disease, chronic liver disease, cirrhosis, and suicide.

The decrease has been particularly devastating among Native Americans and Alaska Natives. Average life expectancy dropped by 4 years in 2020 alone and more than 6.5 years since the beginning of the pandemic. Now their life expectancy is 65, which was the average for all Americans in 1944.

“When I saw that in the report, I just – my jaw dropped,” Dr. Anderson told CNN.

“It was hard enough to fathom a 2.7-year decline over 2 years overall,” he said. “But then to see a 6.6-year decline for the American Indian population, it just shows the substantial impact that the pandemic has had on that population.”

Longstanding health issues and systemic problems, such as poverty, discrimination, and poor access to health care, led to the major declines among Native Americans and Alaska Natives, CNN reported.

“A lot of the talk is going to be around the pandemic, but we need to think about what has driven the conditions that have allowed certain communities to be more vulnerable,” Ruben Cantu, an associate program director with Prevention Institute, a nonprofit focused on health equity, told CNN.

The gap in life expectancy between women and men also became wider in 2021, growing to 5.9 years and marking the largest gap since 1996. The life expectancy for men in 2021 was 73.2, as compared with 79.1 for women.

The decline in overall U.S. life expectancy would have been even greater if there weren’t “offsetting effects,” the researchers wrote, such as declines in death due to the flu, pneumonia, chronic lower respiratory diseases, and Alzheimer’s disease.

The drop in U.S. life expectancy is “historic,” Steven Woolf, MD, retired director of the Center on Society and Health and Virginia Commonwealth University, told the Times.

Other high-income countries also saw a drop in life expectancy in 2020 due to the pandemic, but most began to recover last year due to major vaccine campaigns and behavior changes such as wearing masks, he said.

“None of them experienced a continuing fall in life expectancy like the U.S. did, and a good number of them saw life expectancy start inching back to normal,” he said. “The U.S. is clearly an outlier.”
