Clinician Reviews

TOPLINE:

Most patients who receive antibiotics rather than surgical treatment for appendicitis have successful long-term outcomes, but some may require surgery up to 20 years later.

METHODOLOGY:

• Follow-up on 292 patients involved in two randomized controlled trials conducted in the 1990s by the Swedish National Patient Registry
• Both trials divided patients into two groups: those who underwent appendectomy and those who received antibiotic treatment for appendicitis.
• Researchers looked at rates of recurrent appendicitis that required surgery later in life.

TAKEAWAY:

• 29% of patients in the nonoperative group who were discharged successfully during the initial study eventually underwent surgery.
• Some patients who initially received antibiotics required surgery up to 20 years later.
• 9.5% of patients who didn’t undergo surgery went to a surgical outpatient clinic for abdominal pain, compared with 0.01% of those who had surgery.

IN PRACTICE:

“More than half of the patients treated nonoperatively did not experience recurrence and avoided surgery over approximately 2 decades. There is no evidence for long-term risks of nonoperative management other than that of recurrence of appendicitis,” the authors report.

Simon Eaton, PhD, of UCL Great Ormond Street Institute of Child Health in London, was the corresponding author of the study, published online in JAMA Surgery. The study was funded by the NIHR Biomedical Research Centre at Great Ormond Street Hospital and the Swedish Research Council.

LIMITATIONS:

The data were retrospective, so the researchers could not track how patients’ circumstances and characteristics changed over time. Most patients were male, and the researchers lacked histopathology results for patients for whom nonsurgical treatment succeeded initially but who later required appendectomy. They also relied on diagnostic standards used in the 1990s, when the initial studies were performed; these were less sophisticated and accurate than recent standards.

DISCLOSURES:

Coauthor Jan Svensson, MD, PhD, reported receiving grants from the Lovisa Foundation during the conduct of the study. No other disclosures were reported.

SAN DIEGO – Plasma levels of three proteins involved in growth hormone activity showed significant links to the controllability of type 2 diabetes in children, a finding that suggests these proteins may serve as risk markers for incident type 2 diabetes and help identify adolescents who could benefit from aggressive preventive care.

“Plasma growth hormone mediators are associated with glycemic failure in youth with type 2 diabetes,” Chang Lu, MD, said at the at the annual scientific sessions of the American Diabetes Association. “Our hope is that these mediators could be biomarkers for predicting type 2 diabetes onset,” she added in an interview.

Another potential application is to “leverage these data to find predictive markers” that could identify adolescents with type 2 diabetes “at risk for particularly aggressive disease and target them for more intervention,” added Elvira M. Isganaitis, MD, senior author of the report and a pediatric endocrinologist at the Joslin Diabetes Center in Boston.
 

Does growth hormone cause incident T2D at puberty?

Changes in levels of growth hormone–associated peptides during puberty “could potentially explain why children with type 2 diabetes have a more aggressive course” of the disorder, added Dr. Lu, a pediatric endocrinologist at Joslin and at Boston’s Children’s Hospital.

Puberty-associated changes in growth hormone and related peptides “could be why type 2 diabetes starts during puberty. Type 2 diabetes is almost unheard of before children reach about age 10,” Dr. Isganaitis said in an interview.

A current hypothesis is that “high levels of growth hormone is a cause of insulin resistance during puberty, but in healthy children their beta cells overcome this by making more insulin and so they do not develop diabetes,” said Kristen J. Nadeau, MD, a pediatric endocrinologist and professor at Children’s Hospital Colorado in Denver. 

“But this is a stress situation, and if someone has poor beta-cell function they may develop diabetes. The increase in growth hormone [during puberty] can unmask a physiologic and genetic predisposition” to developing type 2 diabetes, Dr. Nadeau said in an interview.

The analyses run by Dr. Lu, Dr. Isganaitis, and their coauthors used data collected in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study, which randomized 699 children aged 10-17 years with type 2 diabetes to one of three antidiabetes treatment regimens and tallied the subsequent incidence of glycemic failure. The study defined the latter as either 6 months with a hemoglobin A1c level of at least 8% or need for insulin treatment.

The primary outcome showed a 39%-52% incidence of failure during 5 years of follow-up depending on the specific treatments the study participants received.
 

Growth hormone correlates of glycemic failure

The new analyses focused on 310 study participants from TODAY who had plasma specimens available from baseline and a second specimen obtained after 3 years of follow-up. The researchers compared the levels of three peptides that mediate growth hormone signaling at baseline and after 3 years, and assessed these changes relative to the endpoint of glycemic failure.

The results showed that an increase in insulin-like growth factor-1 significantly linked with a reduced incidence of glycemic failure and improved glycemia and beta-cell function.

In contrast, increasing plasma levels of growth hormone receptor significantly linked with an increased rate of glycemic failure, hyperglycemia, insulin resistance, and diminished beta-cell function. Also, an increase in insulin-like growth factor binding protein-1 significantly linked with glycemic failure and hyperglycemia at 36 months, and with higher insulin sensitivity at baseline. All these analyses adjusted for baseline differences in several demographic and clinical variables.

But these post hoc analyses could not determine whether these associations resulted from, or had a causal role in, treatment failure, cautioned Dr. Lu.

Future studies should examine the relationship of growth hormone signaling and the course of glycemic control in children and adolescents with prediabetes and obesity, Dr. Lu said.

Confirming that these growth hormone-related proteins are reliable predictors of future glycemic dysfunction would open the door to studies of interventions to slow or prevent progression to type 2 diabetes in children identified as high risk.

Potential interventions include early initiation of insulin treatment, which could help preserve beta-cell function, or treatment with a glucagon-like peptide-1 (GLP-1) agonist, a class of agents that may interact with the insulin-like growth factor-1 receptors on beta cells, Dr. Lu said.

The study received no commercial funding. Dr. Lu, Dr. Isganaitis, and Dr. Nadeau reported no relevant financial relationships.

Women who continued breast cancer screenings when they reached age 70 had no lower chance of dying from the disease, and just getting a mammogram could instead set them on a path toward unnecessary risks, according to a new study from Yale University.

The findings, published in Annals of Internal Medicine, suggest that between 31% and 54% of all breast cancer diagnoses in women aged 70 years and older could be considered overdiagnoses, meaning that the cancer found during the screening would not have caused symptoms in a person’s lifetime. (For context, the average life expectancy of a woman in the U.S. is 79 years, according to the Centers for Disease Control and Prevention.) 

Overdiagnosis can be harmful because it carries the risks of complications from overtreatment, plus financial and emotional hardships and unnecessary use of limited resources.

For the study, researchers analyzed data for 54,635 women aged 70 and older and compared the rate of breast cancer diagnosis and death among women who did and did not have mammograms during a 15-year follow-up period. 

The rate of breast cancer in the study among women aged 70-74 was 6% for women who were screened and 4% for women who were not screened. The researchers estimated that 31% of the cases were potentially overdiagnosed. Among women aged 75-84, breast cancer was found in 5% of women who were screened, compared to less than 3% of unscreened women. Their estimated overdiagnosis rate was 47%. Finally, 3% of women aged 85 and older who were screened had breast cancer detected, compared with 1% of women in the unscreened group. For the older group, the overdiagnosis rate was 54%.

“While our study focused on overdiagnosis, it is important to acknowledge that overdiagnosis is just one of many considerations when deciding whether to continue screening,” researcher and Yale assistant professor of medicine Ilana Richman, MD, said in a statement. “A patient’s preferences and values, personal risk factors, and the overall balance of risks and benefits from screening are also important to take into account when making screening decisions.”

Young people diagnosed with a genetic heart disease (GHD) predisposing them to ventricular arrhythmia are at very low risk for a cardiac event while playing video games or other electronic games, provided their condition is properly treated, say researchers based on their large, single-center study.

Among more than 3,000 patients in the study with such a genetic vulnerability, just 6 – or less than 0.2% – experienced an electronic gaming–associated cardiac event.

A previous study had concluded that e-gaming, particularly with war games, might trigger potentially fatal arrhythmias in some vulnerable children. That study “sparked controversy in the field, with both clinicians and patients wondering whether electronic gaming is safe for patients with GHDs,” Michael J. Ackerman, MD, PhD, of Mayo Clinic in Rochester, Minn., said in an interview.

Dr. Ackerman and colleagues conducted the current study, published online in the Journal of the American College of Cardiology, to determine just how often e-gaming triggered cardiac events (CE) in these patients – and who was most at risk.
 

‘Extremely low’ risk

The investigators looked at records from all patients evaluated and treated at the Mayo Clinic’s genetic heart rhythm clinic from 2000 to 2022. They identified those with a history of playing electronic games at the time of their CE, defined here as such an event occurring before diagnosis, or breakthrough cardiac event (BCE), meaning an event occurring after diagnosis.

A total of 3,370 patients with a GHD (55% female) were included in the analysis. More than half (52%) were diagnosed with long-QT syndrome (LQTS). The remainder had various GHDs including, among others, catecholaminergic polymorphic ventricular tachycardia (CPVT) or hypertrophic cardiomyopathy (HCM).

The mean age at first evaluation was 27; 14% of the participants were age 6 or younger, 33% were age 7-20, and 53% were 21 or older. Most patients in each of the three age groups were diagnosed with either LQTS or CPVT.

Of the 3,370 GHD patients, 1,079 (32%) had a CE before diagnosis.

Six patients (0.5%) had a CE in the setting of e-gaming, including five for whom it was the sentinel CE. Five also had CEs in settings not involving e-gaming. Their average age at the time of the CE was 13.

Three of the six patients were diagnosed with CPVT (including two CPVT1 and one CPVT2). Of the others, one was diagnosed with LQT1, one with ventricular fibrillation triggered by premature ventricular contractions, and one with catecholamine-sensitive right ventricular outflow tract ventricular tachycardia (RVOT-VT).

After appropriate treatment, none of the six experienced a BCE during follow-ups ranging from 7 months to 4 years.

Among the full cohort of 3370 patients with GHD, 431 (13%) experienced one or more BCE during follow-up. Of those, one with catecholamine-sensitive RVOT-VT experienced an e-gaming–associated BCE.

“Although anecdotal e-gaming–associated cardiac events, including [sudden cardiac death], have been reported, the absolute risk is extremely low,” the authors wrote.

“Although there are no clear health benefits associated with e-gaming,” Dr. Ackerman said, “the risk of sudden death should not be used as an argument in an effort to curtail the amount of time patients spend e-gaming.”

Furthermore, he added, e-gaming is important to some patients’ quality of life. If patients are “properly diagnosed, risk stratified, and treated, it is okay to engage in e-gaming.”

However, “given that e-gaming may pose some risks, especially when compounded with additional factors such as dehydration, sleep deprivation, and use of performance-enhancing substances such as energy drinks, patients need to be counseled on the potential adverse health consequences,” Dr. Ackerman said.

“To this end,” he added, “we are proponents of incorporating e-gaming status into the clinical evaluation and electronic health record.”

“We would continue to urge common sense and individual risk assessment, with shared decision-making, for those where this may be an issue,” Claire M. Lawley, MBBS, PhD, Children’s Hospital at Westmead (Australia), said in an interview.

“Additionally, syncope during electronic gaming should prompt medical review,” said Dr. Lawley, lead author of the study that prompted Ackerman and colleagues to investigate the issue further.
 

Buddy system

Maully J. Shah, MBBS, led a study published in 2020 focusing on two case reports of syncope and potentially life-threatening ventricular arrhythmias provoked by emotional surges during play with violent video games. 

Nevertheless, “we do not restrict patients from participating in e-games,” Dr. Shah, a pediatric cardiac electrophysiologist at the Cardiac Center at Children’s Hospital of Philadelphia, said in an interview. “We inform them about the available data regarding the very rare but possible occurrence of an event from e-gaming so that they can make an informed decision.”

Dr. Shah agreed that, “even in children not known to have a cardiac condition, syncope associated with emotional responses during violent video games should prompt cardiac evaluation, similar to exercise-induced syncope.”

If a patient wishes to play e-games, clinicians should ensure medication compliance and recommend a “buddy” system. “Don’t be alone while playing,” she said.

“The present study and previous reports make one pause to think whether these CEs and catecholaminergic drives can occur with sports only. If we now consider electronic gaming as a potential risk, what other activities need to be included?” wrote the authors of an accompanying editorial, led by Shankar Baskar, MD, Cincinnati Children’s Medical Center.

“A catecholaminergic drive can occur in many settings with activities of daily living or activities not considered to be competitive,” the editorialists wrote. “Ultimately these events [are] rare, but they can have life-threatening consequences, and at the same time they might not be altogether preventable and, as in electronic gaming, might be an activity that improves quality of life, especially in those who might be restricted from other sports.”

Dr. Ackerman disclosed consulting for Abbott, Boston Scientific, Bristol-Myers Squibb, Daiichi Sankyo, Invitae, Medtronic, Tenaya Therapeutics, and UpToDate. Dr. Ackerman and the Mayo Clinic have license agreements with AliveCor, Anumana, ARMGO Pharma, Pfizer, and Thryv Therapeutics. The other coauthors reported no relevant relationships. Dr. Baskar and colleagues reported no relevant relationships. Dr. Shah disclosed she is a consultant to Medtronic.

Of the others, one was diagnosed with LQT1, one with ventricular fibrillation triggered by premature ventricular contractions, and one with catecholamine-sensitive right ventricular outflow tract ventricular tachycardia (RVOT-VT).

After appropriate treatment, none of the six experienced a BCE during follow-ups ranging from 7 months to 4 years.

Among the full cohort of 3370 patients with GHD, 431 (13%) experienced one or more BCE during follow-up. Of those, one with catecholamine-sensitive RVOT-VT experienced an e-gaming–associated BCE.

“Although anecdotal e-gaming–associated cardiac events, including [sudden cardiac death], have been reported, the absolute risk is extremely low,” the authors wrote.

“Although there are no clear health benefits associated with e-gaming,” Dr. Ackerman said, “the risk of sudden death should not be used as an argument in an effort to curtail the amount of time patients spend e-gaming.”

Furthermore, he added, e-gaming is important to some patients’ quality of life. If patients are “properly diagnosed, risk stratified, and treated, it is okay to engage in e-gaming.”

However, “given that e-gaming may pose some risks, especially when compounded with additional factors such as dehydration, sleep deprivation, and use of performance-enhancing substances such as energy drinks, patients need to be counseled on the potential adverse health consequences,” Dr. Ackerman said.

“To this end,” he added, “we are proponents of incorporating e-gaming status into the clinical evaluation and electronic health record.”

“We would continue to urge common sense and individual risk assessment, with shared decision-making, for those where this may be an issue,” Claire M. Lawley, MBBS, PhD, Children’s Hospital at Westmead (Australia), said in an interview.

“Additionally, syncope during electronic gaming should prompt medical review,” said Dr. Lawley, lead author of the study that prompted Ackerman and colleagues to investigate the issue further.
 

Buddy system

Maully J. Shah, MBBS, led a study published in 2020 focusing on two case reports of syncope and potentially life-threatening ventricular arrhythmias provoked by emotional surges during play with violent video games. 

Nevertheless, “we do not restrict patients from participating in e-games,” Dr. Shah, a pediatric cardiac electrophysiologist at the Cardiac Center at Children’s Hospital of Philadelphia, said in an interview. “We inform them about the available data regarding the very rare but possible occurrence of an event from e-gaming so that they can make an informed decision.”

Dr. Shah agreed that, “even in children not known to have a cardiac condition, syncope associated with emotional responses during violent video games should prompt cardiac evaluation, similar to exercise-induced syncope.”

If a patient wishes to play e-games, clinicians should ensure medication compliance and recommend a “buddy” system. “Don’t be alone while playing,” she said.

“The present study and previous reports make one pause to think whether these CEs and catecholaminergic drives can occur with sports only. If we now consider electronic gaming as a potential risk, what other activities need to be included?” wrote the authors of an accompanying editorial, led by Shankar Baskar, MD, Cincinnati Children’s Medical Center.

“A catecholaminergic drive can occur in many settings with activities of daily living or activities not considered to be competitive,” the editorialists wrote. “Ultimately these events [are] rare, but they can have life-threatening consequences, and at the same time they might not be altogether preventable and, as in electronic gaming, might be an activity that improves quality of life, especially in those who might be restricted from other sports.”

Young people diagnosed with a genetic heart disease (GHD) predisposing them to ventricular arrhythmia are at very low risk for a cardiac event while playing video games or other electronic games, provided their condition is properly treated, say researchers based on their large, single-center study.

Among more than 3,000 patients in the study with such a genetic vulnerability, just 6 – or less than 0.2% – experienced an electronic gaming–associated cardiac event.

A previous study had concluded that e-gaming, particularly with war games, might trigger potentially fatal arrhythmias in some vulnerable children. That study “sparked controversy in the field, with both clinicians and patients wondering whether electronic gaming is safe for patients with GHDs,” Michael J. Ackerman, MD, PhD, of Mayo Clinic in Rochester, Minn., said in an interview.

Dr. Ackerman and colleagues conducted the current study, published online in the Journal of the American College of Cardiology, to determine just how often e-gaming triggered cardiac events (CE) in these patients – and who was most at risk.
 

‘Extremely low’ risk

The investigators looked at records from all patients evaluated and treated at the Mayo Clinic’s genetic heart rhythm clinic from 2000 to 2022. They identified those with a history of playing electronic games at the time of their CE, defined here as such an event occurring before diagnosis, or breakthrough cardiac event (BCE), meaning an event occurring after diagnosis.

A total of 3,370 patients with a GHD (55% female) were included in the analysis. More than half (52%) were diagnosed with long-QT syndrome (LQTS). The remainder had various GHDs including, among others, catecholaminergic polymorphic ventricular tachycardia (CPVT) or hypertrophic cardiomyopathy (HCM).

The mean age at first evaluation was 27; 14% of the participants were age 6 or younger, 33% were age 7-20, and 53% were 21 or older. Most patients in each of the three age groups were diagnosed with either LQTS or CPVT.

Of the 3,370 GHD patients, 1,079 (32%) had a CE before diagnosis.

Six patients (0.5%) had a CE in the setting of e-gaming, including five for whom it was the sentinel CE. Five also had CEs in settings not involving e-gaming. Their average age at the time of the CE was 13.

Three of the six patients were diagnosed with CPVT (including two CPVT1 and one CPVT2). Of the others, one was diagnosed with LQT1, one with ventricular fibrillation triggered by premature ventricular contractions, and one with catecholamine-sensitive right ventricular outflow tract ventricular tachycardia (RVOT-VT).

After appropriate treatment, none of the six experienced a BCE during follow-ups ranging from 7 months to 4 years.

Among the full cohort of 3370 patients with GHD, 431 (13%) experienced one or more BCE during follow-up. Of those, one with catecholamine-sensitive RVOT-VT experienced an e-gaming–associated BCE.

In a large cohort of older adults with type 2 diabetes in Italy, those with the highest intake of ultraprocessed food and beverages (UPF) were more likely to die of all causes or cardiovascular disease (CVD) within a decade than those with the lowest intake – independent of adherence to a healthy Mediterranean diet.

Adults in the top quartile of UPF intake had a 64% increased risk of all-cause death and a 2.5-fold increased risk of CVD death during follow-up, compared with those in the lowest quartile, after adjusting for variables including Mediterranean diet score.

These findings from the Moli-sani study by Marialaura Bonaccio, PhD, from the Institute for Research, Hospitalization and Healthcare (IRCCS) Neuromed, in Pozzilli, Italy, and colleagues, were published online in the American Journal of Clinical Nutrition.

“Dietary recommendations for prevention and management of type 2 diabetes almost exclusively prioritize consumption of nutritionally balanced foods that are the source of fiber [and] healthy fats and [are] poor in free sugars, and promote dietary patterns – such as the Mediterranean diet and the DASH diet – that place a large emphasis on food groups (for example, whole grains, legumes, nuts, fruits, and vegetables) regardless of food processing,” the researchers note.

The research suggests that “besides prioritizing the adoption of a diet based on nutritional requirements, dietary guidelines for the management of type 2 diabetes should also recommend limiting UPF,” they conclude.

“In addition to the adoption of a diet based on well-known nutritional requirements, dietary recommendations should also suggest limiting the consumption of ultraprocessed foods as much as possible,” Giovanni de Gaetano, MD, PhD, president, IRCCS Neuromed, echoed, in a press release from the institute.

“In this context, and not only for people with diabetes, the front-of-pack nutrition labels should also include information on the degree of food processing,” he observed.

Caroline M. Apovian, MD, who was not involved with the study, agrees that it is wise to limit consumption of UPF.

However, we need more research to better understand which components of UPF are harmful and the biologic mechanisms, Dr. Apovian, who is codirector, Center for Weight Management and Wellness, Brigham and Women’s Hospital, and a professor of medicine at Harvard Medical School, both in Boston, told this news organization in an interview.

She noted that in a randomized crossover trial in 20 patients who were instructed to eat as much or as little as they wanted, people ate more and gained weight during 2 weeks of a diet high in UPF, compared with 2 weeks of an unprocessed diet matched for presented calories, carbohydrate, sugar, fat, sodium, and fiber.
 

Ultraprocessed foods classed according to Nova system

UPF is “made mostly or entirely from substances derived from foods and additives, using a series of processes and containing minimal whole foods,” and they “are usually nutrient-poor, high in calories, added sugar, sodium, and unhealthy fats,” the Italian researchers write.

High intake of UPF, they add, may exacerbate health risks in people with type 2 diabetes, who are already at higher risk of premature mortality, mainly due to diabetes-related complications.

The researchers analyzed data from a subset of patients in the Moli-sani study of environmental and genetic factors underlying disease, which enrolled 24,325 individuals aged 35 and older who lived in Molise, in central-southern Italy, in 2005-2010.

The current analysis included 1,065 participants in Moli-sani who had type 2 diabetes at baseline and completed a food frequency questionnaire by which participants reported their consumption of 188 foods and beverages in the previous 12 months.

Participants were a mean age of 65 years, and 60% were men.

Most UPF intake was from processed meat (22.4%), crispbread/rusks (16.6%), nonhomemade pizza (11.2%), and cakes, pies, pastries, and puddings (8.8%).

Researchers categorized foods and beverages into four groups with increasing degrees of processing, based on the Nova Food Classification System:

• Group 1: Fresh or minimally processed foods and beverages (for example, fruit, meat, milk).
• Group 2: Processed culinary ingredients (for example, oils, butter).
• Group 3: Processed foods and beverages (for example, canned fish, bread).
• Group 4: UPF (22 foods and beverages including carbonated drinks, processed meats, sweet or savory packaged snacks, margarine, and foods and beverages with artificial sweeteners).

Participants were divided into four quartiles based on UPF consumption.

The mean percentage of UPF consumption out of total food and beverage intake was 2.8%, 5.2%, 7.7%, and 14.4% for quartiles 1, 2, 3, and 4, respectively. By sex, these rates for quartile 1 were < 4.7% for women and < 3.7% for men, and for quartile 4 were ≥ 10.5% for women and ≥ 9% for men.

Participants with the highest UPF intake were younger (mean age, 63 vs. 67 years) but otherwise had similar characteristics as other participants.

During a median follow-up of 11.6 years, 308 participants died from all causes, including 129 who died from CVD.

Compared with participants with the lowest intake of UPF (quartile 1), those with the highest intake (quartile 4) had a higher risk of all-cause mortality (hazard ratio, 1.70) and CVD mortality (HR, 2.64) during follow-up, after multivariable adjustment. The analysis adjusted for sex, age, energy intake, residence, education, housing, smoking, body mass index, leisure-time physical activity, history of cancer or cardiovascular disease, hypertension, hyperlipidemia, aspirin use, years since type 2 diabetes diagnosis, and special diet for blood glucose control.

After further adjusting for Mediterranean diet score, the risk of all-cause and CVD mortality during follow-up for patients with the highest versus lowest intake of UPF remained similar (HR, 1.64 and 2.55, respectively).

There was a linear dose–response relationship between UPF and all-cause and CVD mortality.

Increasing intake of fruit drinks, carbonated drinks, and salty biscuits was associated with higher all-cause and CVD mortality rates, and consumption of stock cubes and margarine was further related to higher CVD death.

The researchers acknowledge that the study was observational, and therefore cannot determine cause and effect, and was not designed to specifically collect dietary data according to the Nova classification. The findings may not be generalizable to other populations.

The analysis was partly funded by grants from the AIRC and Italian Ministry of Health. The authors have reported no relevant financial relationships.

Newly discovered genes could explain body fat differences between men and women with obesity, as well as why some people gain excess weight in childhood.

Identifying specific genes adds to growing evidence that biology, in part, drives obesity. Researchers hope the findings will lead to effective treatments, and in the meantime add to the understanding that there are many types of obesity that come from a mix of genes and environmental factors.

Although the study is not the first to point to specific genes, “we were quite surprised by the proposed function of some of the genes we identified,” Lena R. Kaisinger, lead study investigator and a PhD student in the MRC Epidemiology Unit at the University of Cambridge (England), wrote in an email. For example, the genes also manage cell death and influence how cells respond to DNA damage. 

The investigators are not sure why genes involved in body size perform this kind of double duty, which opens avenues for future research.

The gene sequencing study was published online in the journal Cell Genomics.
 

Differences between women and men

The researchers found five new genes in females and two new genes in males linked to greater body mass index (BMI): DIDO1, KIAA1109, MC4R, PTPRG and SLC12A5 in women and MC4R and SLTM in men. People who recall having obesity as a child were more likely to have rare genetic changes in two other genes, OBSCN and MADD.

“The key thing is that when you see real genes with real gene names, it really makes real the notion that genetics underlie obesity,” said Lee Kaplan, MD, PhD, director of the Obesity and Metabolism Institute in Boston, who was not affiliated with the research.

Ms. Kaisinger and colleagues found these significant genetic differences by studying genomes of about 420,000 people stored in the UK Biobank, a huge biomedical database. The researchers decided to look at genes by sex and age because these are “two areas that we still know very little about,” Ms. Kaisinger said.

“We know that different types of obesity connect to different ages,” said Dr. Kaplan, who is also past president of the Obesity Society. “But what they’ve done now is find genes that are associated with particular subtypes of obesity ... some more common in one sex and some more common in different phases of life, including early onset obesity.”
 

The future is already here

Treatment for obesity based on a person’s genes already exists. For example, in June 2022, the Food and Drug Administration approved setmelanotide (Imcivree) for weight management in adults and children aged over 6 years with specific genetic markers. 

Even as encouraging as setmelanotide is to Ms. Kaisinger and colleagues, these are still early days for translating the current research findings into clinical obesity tests and potential treatment, she said.

The “holy grail,” Dr. Kaplan said, is a future where people get screened for a particular genetic profile and their provider can say something like, “You’re probably most susceptible to this type, so we’ll treat you with this particular drug that’s been developed for people with this phenotype.”

Dr. Kaplan added: “That’s exactly what we are trying to do.”

Moving forward, Ms. Kaisinger and colleagues plan to repeat the study in larger and more diverse populations. They also plan to reverse the usual road map for studies, which typically start in animals and then progress to humans.

“We plan to take the most promising gene candidates forward into mouse models to learn more about their function and how exactly their dysfunction results in obesity,” Ms. Kaisinger said. 

Three study coauthors are employees and shareholders of Adrestia Therapeutics. No other conflicts of interest were reported.

The researchers found five new genes in females and two new genes in males linked to greater body mass index (BMI): DIDO1, KIAA1109, MC4R, PTPRG and SLC12A5 in women and MC4R and SLTM in men. People who recall having obesity as a child were more likely to have rare genetic changes in two other genes, OBSCN and MADD.

“The key thing is that when you see real genes with real gene names, it really makes real the notion that genetics underlie obesity,” said Lee Kaplan, MD, PhD, director of the Obesity and Metabolism Institute in Boston, who was not affiliated with the research.

Ms. Kaisinger and colleagues found these significant genetic differences by studying genomes of about 420,000 people stored in the UK Biobank, a huge biomedical database. The researchers decided to look at genes by sex and age because these are “two areas that we still know very little about,” Ms. Kaisinger said.

“We know that different types of obesity connect to different ages,” said Dr. Kaplan, who is also past president of the Obesity Society. “But what they’ve done now is find genes that are associated with particular subtypes of obesity ... some more common in one sex and some more common in different phases of life, including early onset obesity.”
 

The future is already here

Treatment for obesity based on a person’s genes already exists. For example, in June 2022, the Food and Drug Administration approved setmelanotide (Imcivree) for weight management in adults and children aged over 6 years with specific genetic markers. 

Even as encouraging as setmelanotide is to Ms. Kaisinger and colleagues, these are still early days for translating the current research findings into clinical obesity tests and potential treatment, she said.

The “holy grail,” Dr. Kaplan said, is a future where people get screened for a particular genetic profile and their provider can say something like, “You’re probably most susceptible to this type, so we’ll treat you with this particular drug that’s been developed for people with this phenotype.”

Dr. Kaplan added: “That’s exactly what we are trying to do.”

Moving forward, Ms. Kaisinger and colleagues plan to repeat the study in larger and more diverse populations. They also plan to reverse the usual road map for studies, which typically start in animals and then progress to humans.

“We plan to take the most promising gene candidates forward into mouse models to learn more about their function and how exactly their dysfunction results in obesity,” Ms. Kaisinger said.

Newly discovered genes could explain body fat differences between men and women with obesity, as well as why some people gain excess weight in childhood.

Identifying specific genes adds to growing evidence that biology, in part, drives obesity. Researchers hope the findings will lead to effective treatments, and in the meantime add to the understanding that there are many types of obesity that come from a mix of genes and environmental factors.

Although the study is not the first to point to specific genes, “we were quite surprised by the proposed function of some of the genes we identified,” Lena R. Kaisinger, lead study investigator and a PhD student in the MRC Epidemiology Unit at the University of Cambridge (England), wrote in an email. For example, the genes also manage cell death and influence how cells respond to DNA damage. 

The investigators are not sure why genes involved in body size perform this kind of double duty, which opens avenues for future research.

As we navigate the ever-evolving landscape of diabetic foot disease management, I’d like to discuss the updated 2023 International Working Group on the Diabetic Foot guidelines and their implications for our practice. The goal is to create a common language of risk that is easily related from clinician to clinician to patient.

Whatever language we use, though, the problem we face is vast:

• Diabetic foot ulcers affect approximately 18.6 million people worldwide and 1.6 million in the United States each year.
• They are associated with high rates of premature death, with a 5-year mortality rate of 30%. This rate is greater than 70% for those with above-foot amputations, worse than all but the most aggressive cancers.
• The direct costs of treating diabetic foot ulcers in the United States is estimated at $9 billion-$13 billion annually.
• Over 550 million people worldwide have diabetes, with 18.6 million developing foot ulcers annually. Up to 34% of those with diabetes will develop a foot ulcer.
• About 20% of those with a diabetic foot ulcer will undergo amputation, a major cause of which is infection, which affects 50% of foot ulcers.
• Up to 20% of those with a foot ulcer require hospitalization, with 15%-20% undergoing amputation. Inequities exist in diabetes-related foot complications:
• –Rates of major amputation are higher in non-Hispanic Black, Hispanic, and Native American populations, compared with non-Hispanic White populations.
• –Non-Hispanic Black and Hispanic populations present with more advanced ulcers and peripheral artery disease, and are more likely to undergo amputation without revascularization attempt.

The IWGDF, a multidisciplinary team of international experts, has recently updated its guidelines. This team, comprising endocrinologists, internal medicine physicians, physiatrists, podiatrists, and vascular surgeons from across the globe, has worked tirelessly to provide us with a comprehensive guide to managing diabetes-related foot ulcers.

The updated guidelines address five critical clinical questions, each with up to 13 important outcomes. The systematic review that underpins these guidelines identified 149 eligible studies, assessing 28 different systems. This exhaustive research has led to the development of seven key recommendations that address the clinical questions and consider the existence of different clinical settings.

One of the significant updates in the 2023 guidelines is the recommendation of SINBAD – site, ischemia, neuropathy, bacterial infection, area, and depth – as the priority wound classification system for people with diabetes and a foot ulcer. This system is particularly useful for interprofessional communication, describing each composite variable, and conducting clinical audits using the full score. However, the guidelines also recommend the use of other, more specific assessment systems for infection and peripheral artery disease from the Infectious Diseases Society of America/IWGDF when resources and an appropriate level of expertise exist.

The introduction of the Wound, Ischemia and Foot Infection (WIfI) classification system in the guidelines is also a noteworthy development. This system is crucial in assessing perfusion and the likely benefit of revascularization in a person with diabetes and a foot ulcer. By assessing the level of wound ischemia and infection, we can make informed decisions about the need for vascular intervention, which can significantly affect the patient’s outcome. This can be done simply by classifying each of the three categories of wound, ischemia, or foot infection as none, mild, moderate, or severe. By simplifying the very dynamic comorbidities of tissue loss, ischemia, and infection into a usable and predictive scale, it helps us to communicate risk across disciplines. This has been found to be highly predictive of healing, amputation, and mortality.

We use WIfI every day across our system. An example might include a patient we recently treated:

A 76-year-old woman presented with a wound to her left foot. Her past medical history revealed type 2 diabetes, peripheral neuropathy, and documented peripheral artery disease with prior bilateral femoral-popliteal bypass conducted at an external facility. In addition to gangrenous changes to her fourth toe, she displayed erythema and lymphangitic streaking up her dorsal foot. While she was afebrile, her white cell count was 13,000/mcL. Radiographic examinations did not show signs of osteomyelitis. Noninvasive vascular evaluations revealed an ankle brachial index of 0.4 and a toe pressure of 10 mm Hg. An aortogram with a lower-extremity runoff arteriogram confirmed the obstruction of her left femoral-popliteal bypass.

Taking these results into account, her WIfI score was determined as: wound 2 (moderate), ischemia 3 (severe), foot infection 2 (moderate, no sepsis), translating to a clinical stage 4. This denotes a high risk for major amputation.

Following a team discussion, she was taken to the operating room for an initial debridement of her infection which consisted of a partial fourth ray resection to the level of the mid-metatarsal. Following control of the infection, she received a vascular assessment which ultimately constituted a femoral to distal anterior tibial bypass. Following both of these, she was discharged on a negative-pressure wound therapy device, receiving a split-thickness skin graft 4 weeks later.

The guidelines also emphasize the need for specific training, skills, and experience to ensure the accuracy of the recommended systems for characterizing foot ulcers. The person applying these systems should be appropriately trained and, according to their national or regional standards, should have the knowledge, expertise, and skills necessary to manage people with a diabetes-related foot ulcer.

As we continue to navigate the complexities of diabetes-related foot disease, these guidelines serve as a valuable compass, guiding our decisions and actions. They remind us of the importance of continuous learning, collaboration, and the application of evidence-based practice in our work.

I encourage you to delve into these guidelines. Let’s use them to improve our practice, enhance our communication, and, ultimately, provide better care for our patients.

As with porridge, so with blood pressure: Just right makes all the difference.

Ill-fitting blood pressure measurement cuffs produce erroneous readings that impair hypertension treatment, according to research published in JAMA Internal Medicine.

People whose mid-upper arm circumference exceeds 32 cm require larger cuffs than the standard size, but in many cases the regular-sized cuff is used on everyone. As a result, patients with larger arms may be falsely diagnosed with high blood pressure because of a too-small cuff, leading to overprescribing of medications that could make their health worse, according to the researchers.  

“A person whose blood pressure is 120/80, which is normal – if they’re using the wrong cuff, they could get a measurement that says 140/90, let’s say,” said study author Tammy M. Brady, MD, PhD, vice chair for clinical research in the department of pediatrics at Johns Hopkins University, Baltimore. “They might think they not only have hypertension, but stage 2 hypertension. Providers might give one or even two medicines to lower this, which could lead to hypotension,” Dr. Brady said.

Conversely, someone with smaller arms whose cuff is too big may present with an artificially low blood pressure. The implications of using ill-fitting cuffs are well known. Dr. Brady, among others, has studied the topic extensively. Even so, she said the measurement errors in the latest study were larger than expected.
 

The Goldilocks test

People with an arm circumference of 20-25 cm should use a smaller cuff than the regular size, Dr. Brady and colleagues reported. Circumferences of 25.1-32 cm require a regular-sized cuff; large cuffs are for circumferences of 32.1-40 cm; and extra-large cuffs should be used at 40.1-55 cm.

The study included 195 residents of Baltimore (128 women, 67 men; 132 Black, 58 White, 5 Hispanic) with an average age of 54 years. The researchers measured every participant’s blood pressure using an automated device on four occasions, taking three measurements each time.

The first three sets of measurements used, respectively, an appropriate cuff size for each person’s arm circumference; a cuff that was too big; and a cuff that was too small. This study design ensured that a regular-sized cuff would be used during one of the three measurements – sometimes that cuff was too small, sometimes it was appropriate, and other times it was too big.

The final set of three measurements used the appropriate cuff size for a person’s arm every time. Dr. Brady and colleagues then compared people’s blood pressure measurements when using the right-sized cuff to measurements with a regular-sized cuff that was not suited for them.

They found that using a cuff that was too large for the patient’s arm (i.e., using a regular cuff when a small cuff was the right choice) led to understating systolic blood pressure by –3.6 mm Hg (95% confidence interval [CI], –5.6 to –1.7). A cuff that was one size too small – using regular instead of a large – overestimated systolic blood pressure by 4.8 (3.0-6.6) mm Hg. And a cuff that was two sizes too small – someone who should have received an extra-large cuff but received the regular size – overestimated systolic blood pressure by 19.5 (16.1-22.9) mm Hg. All differences were statistically significant, the researchers reported.

“To our knowledge, this is the first randomized cross-over trial to examine the effect of miscuffing on automated blood pressure readings,” Mathias Lalika, MD, MPH, of the Mayo Clinic in Rochester, Minn.; Stephen P. Juraschek, MD, PhD, of Beth Israel Deaconess Medical Center in Boston; and LaPrincess C. Brewer, MD, MPH, of the Mayo Clinic, wrote in an editorial accompanying the journal article.

“Interestingly, the degree of underestimation or overestimation increased as the appropriate cuff size progressed from the regular to extra-large BP cuff. More importantly, the effect of miscuffing did not vary with BP or obesity status,” they wrote.

“This was more of a pragmatic trial to see real world, all comers,” Dr. Brady said, when regular-sized cuffs are used whether or not that made sense.

“This study reaffirms findings of previous studies and highlights a major source of error in blood pressure measurement,” Raj Padwal, MD, director of the University of Alberta Hypertension Clinic, Edmonton, Alta., said in an interview. Dr. Padwal, who was not involved in the study, said the findings highlight the importance of ensuring that technicians who typically measure blood pressure understand the value of using the right-sized cuff.

Dr. Brady noted that measuring arm circumference takes about 15 seconds. He advised health organizations and clinics to carry multiple cuffs sizes to avoid a scramble to find a right-sized cuff. In the editorial, Dr. Lalika, Dr. Juraschek, and Dr. Brewer call for particular attention to providing the right-sized cuffs to facilities that work with underserved populations, such as federally qualified health centers.

Dr. Padwal added that even a perfectly measured blood pressure test at a clinic indicates pressure at a moment in time. Ten minutes later the story could be different. For this reason, he and other clinicians recommend frequent home blood pressure measurements rather than relying solely on the sparse number of readings collected in the clinic setting.

“A properly educated patient can give many readings that are separated in space and time and, when averaged, can give a much better picture of overall blood pressure and future risk,” Dr. Padwal said. 

Dr. Brady agreed with the value of home readings but said home-based readings also can be erroneous if the patient uses a cuff that is the wrong size. She cochairs a committee for the American Medical Association that recommends validated home blood pressure measurement devices on a periodically updated website called Validate BP. The details for each device listing show the cuff sizes available per device. Many devices provide only the standard cuff, Dr. Brady noted, but some offer multiple cuff sizes.

“One of the things that would be great if it came out of this paper is if patients were empowered to ask physicians to measure their arm” and then use that information to select the appropriate cuff for their home device, she said.

Dr. Brady and Dr. Padwal reported no relevant financial relationships. This study was supported by Resolve to Save Lives, which is funded by Bloomberg Philanthropies, the Bill & Melinda Gates Foundation, and Gates Philanthropy Partners, which is funded with support from the Chan Zuckerberg Foundation.

Dr. Brady noted that measuring arm circumference takes about 15 seconds. He advised health organizations and clinics to carry multiple cuffs sizes to avoid a scramble to find a right-sized cuff. In the editorial, Dr. Lalika, Dr. Juraschek, and Dr. Brewer call for particular attention to providing the right-sized cuffs to facilities that work with underserved populations, such as federally qualified health centers.

Dr. Padwal added that even a perfectly measured blood pressure test at a clinic indicates pressure at a moment in time. Ten minutes later the story could be different. For this reason, he and other clinicians recommend frequent home blood pressure measurements rather than relying solely on the sparse number of readings collected in the clinic setting.

“A properly educated patient can give many readings that are separated in space and time and, when averaged, can give a much better picture of overall blood pressure and future risk,” Dr. Padwal said. 

Dr. Brady agreed with the value of home readings but said home-based readings also can be erroneous if the patient uses a cuff that is the wrong size. She cochairs a committee for the American Medical Association that recommends validated home blood pressure measurement devices on a periodically updated website called Validate BP. The details for each device listing show the cuff sizes available per device. Many devices provide only the standard cuff, Dr. Brady noted, but some offer multiple cuff sizes.

“One of the things that would be great if it came out of this paper is if patients were empowered to ask physicians to measure their arm” and then use that information to select the appropriate cuff for their home device, she said.

Dr. Brady and Dr. Padwal reported no relevant financial relationships.

As with porridge, so with blood pressure: Just right makes all the difference.

Ill-fitting blood pressure measurement cuffs produce erroneous readings that impair hypertension treatment, according to research published in JAMA Internal Medicine.

People whose mid-upper arm circumference exceeds 32 cm require larger cuffs than the standard size, but in many cases the regular-sized cuff is used on everyone. As a result, patients with larger arms may be falsely diagnosed with high blood pressure because of a too-small cuff, leading to overprescribing of medications that could make their health worse, according to the researchers.  

“A person whose blood pressure is 120/80, which is normal – if they’re using the wrong cuff, they could get a measurement that says 140/90, let’s say,” said study author Tammy M. Brady, MD, PhD, vice chair for clinical research in the department of pediatrics at Johns Hopkins University, Baltimore. “They might think they not only have hypertension, but stage 2 hypertension. Providers might give one or even two medicines to lower this, which could lead to hypotension,” Dr. Brady said.

Conversely, someone with smaller arms whose cuff is too big may present with an artificially low blood pressure. The implications of using ill-fitting cuffs are well known. Dr. Brady, among others, has studied the topic extensively. Even so, she said the measurement errors in the latest study were larger than expected.
 

The Goldilocks test

People with an arm circumference of 20-25 cm should use a smaller cuff than the regular size, Dr. Brady and colleagues reported. Circumferences of 25.1-32 cm require a regular-sized cuff; large cuffs are for circumferences of 32.1-40 cm; and extra-large cuffs should be used at 40.1-55 cm.

The study included 195 residents of Baltimore (128 women, 67 men; 132 Black, 58 White, 5 Hispanic) with an average age of 54 years. The researchers measured every participant’s blood pressure using an automated device on four occasions, taking three measurements each time.

The first three sets of measurements used, respectively, an appropriate cuff size for each person’s arm circumference; a cuff that was too big; and a cuff that was too small. This study design ensured that a regular-sized cuff would be used during one of the three measurements – sometimes that cuff was too small, sometimes it was appropriate, and other times it was too big.

The final set of three measurements used the appropriate cuff size for a person’s arm every time. Dr. Brady and colleagues then compared people’s blood pressure measurements when using the right-sized cuff to measurements with a regular-sized cuff that was not suited for them.

They found that using a cuff that was too large for the patient’s arm (i.e., using a regular cuff when a small cuff was the right choice) led to understating systolic blood pressure by –3.6 mm Hg (95% confidence interval [CI], –5.6 to –1.7). A cuff that was one size too small – using regular instead of a large – overestimated systolic blood pressure by 4.8 (3.0-6.6) mm Hg. And a cuff that was two sizes too small – someone who should have received an extra-large cuff but received the regular size – overestimated systolic blood pressure by 19.5 (16.1-22.9) mm Hg. All differences were statistically significant, the researchers reported.

“To our knowledge, this is the first randomized cross-over trial to examine the effect of miscuffing on automated blood pressure readings,” Mathias Lalika, MD, MPH, of the Mayo Clinic in Rochester, Minn.; Stephen P. Juraschek, MD, PhD, of Beth Israel Deaconess Medical Center in Boston; and LaPrincess C. Brewer, MD, MPH, of the Mayo Clinic, wrote in an editorial accompanying the journal article.

“Interestingly, the degree of underestimation or overestimation increased as the appropriate cuff size progressed from the regular to extra-large BP cuff. More importantly, the effect of miscuffing did not vary with BP or obesity status,” they wrote.

“This was more of a pragmatic trial to see real world, all comers,” Dr. Brady said, when regular-sized cuffs are used whether or not that made sense.

“This study reaffirms findings of previous studies and highlights a major source of error in blood pressure measurement,” Raj Padwal, MD, director of the University of Alberta Hypertension Clinic, Edmonton, Alta., said in an interview. Dr. Padwal, who was not involved in the study, said the findings highlight the importance of ensuring that technicians who typically measure blood pressure understand the value of using the right-sized cuff.

I’m Dr. Kenny Lin. I am a family physician and associate director of the Lancaster General Hospital Family Medicine Residency, and I blog at Common Sense Family Doctor.

I’m 47 years old. Two years ago, when the U.S. Preventive Services Task Force (USPSTF) followed the American Cancer Society and lowered the starting age for colorectal cancer (CRC) screening from 50 to 45, my family physician brought up screening options at a health maintenance visit. Although I had expressed some skepticism about this change when the ACS updated its screening guideline in 2018, I generally follow the USPSTF recommendations in my own clinical practice, so I dutifully selected a test that, fortunately, came out negative.

Not everyone in the primary care community, however, is on board with screening average-risk adults in their late 40s for colorectal cancer. The American Academy of Family Physicians (AAFP) published a notable dissent, arguing that the evidence from modeling studies cited by the USPSTF to support lowering the starting age was insufficient. The AAFP also expressed concern that devoting screening resources to younger adults could come at the expense of improving screening rates in older adults who are at higher risk for CRC and increase health care costs without corresponding benefit.

Now, the American College of Physicians has joined the AAFP by releasing an updated guidance statement for CRC screening that discourages screening asymptomatic, average-risk adults between the ages of 45 and 49. In addition to the uncertainty surrounding benefits of screening adults in this age range, the ACP pointed out that starting screening at age 45, compared with age 50, would increase the number of colonoscopies and colonoscopy complications. My colleagues and I recently published a systematic review estimating that for every 10,000 screening colonoscopies performed, 8 people suffer a bowel perforation and 16 to 36 have severe bleeding requiring hospitalization. One in 3 patients undergoing colonoscopies report minor adverse events such as abdominal pain, bloating, and abdominal discomfort in the first 2 weeks following the procedure.

Other aspects of the ACP guidance differ from other colorectal cancer screening guidelines. Unlike the USPSTF, which made no distinctions between various recommended screening tests, the ACP preferentially endorsed fecal immunochemical or high-sensitivity fecal occult blood testing every 2 years, colonoscopy every 10 years, or flexible sigmoidoscopy every 10 years plus a fecal immunochemical test every 2 years. That leaves out stool DNA testing, which my patients increasingly request because they have seen television or online advertisements, and newer blood tests that detect methylation sequences in circulating tumor DNA.

Perhaps most controversial is the ACP’s suggestion that it is probably reasonable for some adults to start screening later than age 50 or undergo screening at longer intervals than currently recommended (for example, colonoscopy every 15 years). Recent data support extending the interval to repeat screening colonoscopy in selected populations; a large cross-sectional study found a low prevalence of advanced adenomas and colorectal cancers in colonoscopies performed 10 or more years after an initial negative colonoscopy, particularly in women and younger patients without gastrointestinal symptoms. A prominent BMJ guideline suggests that patients need not be screened until their estimated 15-year CRC risk is greater than 3% (which most people do not reach until their 60s) and then only need a single sigmoidoscopy or colonoscopy.

Despite some departures from other guidelines, it’s worth emphasizing that the ACP guideline agrees that screening for CRC is generally worthwhile between the ages of 50 and 75 years. On that front, we in primary care have more work to do; the Centers for Disease Control and Prevention estimates that 28% of American adults older than 50 are not up-to-date on CRC screening. And despite some recent debate about the relative benefits and harms of screening colonoscopy, compared with less invasive fecal tests, gastroenterologists and family physicians can agree that the best screening test is the test that gets done.

COVID-19 hospitalizations continue their steady summer march upward, and now a new variant has perched atop the list of the most prevalent forms of the virus.

Called “Eris” among avid COVID trackers, the strain EG.5 now accounts for 17% of all U.S. COVID infections, according to the latest Centers for Disease Control and Prevention estimates. That’s up from 12% the week prior. 

EG.5 has been rising worldwide, just weeks after the World Health Organization added the strain to its official monitoring list. In the United Kingdom, it now accounts for 1 in 10 COVID cases, The Independent reported.

EG.5 is a descendant of the XBB strains that have dominated tracking lists in recent months. It has the same makeup as XBB.1.9.2 but carries an extra spike mutation, according to a summary published by the Center for Infectious Disease Research and Policy at the University of Minnesota. The spike protein is the part of the virus that allows it to enter human cells. But there’s no indication so far that EG.5 is more contagious or severe than other recent variants, according to the CIDRAP summary and a recent podcast from the American Medical Association. The CDC said that current vaccines protect against the variant.

U.S. hospitals saw a 12% increase in COVID admissions during the week ending on July 22, with 8,047 people being admitted because of the virus, up from an all-time low of 6,306 the week of June 24. In 17 states, the past-week increase in hospitalizations was 20% or greater. In Minnesota, the rate jumped by 50%, and in West Virginia, it jumped by 63%. Meanwhile, deaths reached their lowest weekly rate ever for the week of data ending July 29, with just 176 deaths reported by the CDC.
