TOPLINE:

Changes in plasma growth hormone mediators such as growth hormone receptor (GHR) and insulin-like growth factor-binding protein 1 (IGFBP-1) were associated with glycemic failure in youth-onset type 2 diabetes (T2D), an analysis of the TODAY trial showed.

METHODOLOGY:

• In youth, T2D often occurs during or after puberty, hinting at hormonal influences in the development and/or progression of the disease.
• This secondary analysis assessed the role of growth hormone mediators including insulin-like growth factor-1 (IGF-1), GHR, and IGFBP-1 in glycemic failure in a subset of 398 youths, aged 10-17 years, with a T2D duration of less than 2 years (62% girls; 21% White).
• The participants were followed up for a mean of 3.9 years.
• The primary outcomes included glycemic failure, defined as an A1c level of 8% or more for 6 months, or acute metabolic decompensation requiring insulin.
• Other assessments included baseline and 36-month measures of glycemia, insulin sensitivity, high molecular weight adiponectin, and beta cell function.

TAKEAWAY:

• Of 398 participants, 182 (46%) experienced glycemic failure, while 216 (54%) retained glycemic control.
• At 36 months, youths with glycemic failure had lower IGF-1 levels (P < .001) and higher log₂ GHR (P = .03) and log₂ IGFBP-1 (P = .009) levels than those who maintained glycemic control.
• A greater increase in IGF-1 level at 36 months was associated with lower odds of glycemic failure (odds ratio [OR], 0.995; P < .001).
• Increased levels of log₂ GHR and log₂ IGFBP-1 were associated with higher odds of glycemic failure (OR, 1.75; P = .04 and OR, 1.37; P = .007, respectively). Results were adjusted for body mass index (BMI), suggesting that associations between GHR level and glycemic outcomes exist independent of BMI.
• Interhormonal correlations suggested an association between glucose metabolism and growth hormone signaling or a shared process leading to changes in both processes.

IN PRACTICE:

“Our study has identified GHR level as a novel biomarker of decrease in glycemic control in youths with T2D,” the study authors wrote. Future research is needed, with an emphasis on assessing alterations in growth hormone mediators which may contribute to diabetes complications in youth.

SOURCE:

The study, published online in JAMA Network Open, was led by Chang Lu, MD, Division of Endocrinology, Boston Children’s Hospital, and Joslin Diabetes Center at Harvard Medical School, Boston, Massachusetts.

LIMITATIONS:

The study did not include a control group (individuals without diabetes). The cohort largely included youth in late puberty or after puberty, affecting subgroup analysis. Moreover, only circulating growth hormone mediators were measured, limiting the identity of the source tissue of the hormone and the target organs.

DISCLOSURES:

Some authors reported receiving grants from the National Institutes of Health and National Institute of Diabetes and Digestive and Kidney Diseases while conducting the study. Also, certain authors reported receiving grants and personal fees from various trusts as well as pharmaceutical, healthcare, and medical technology companies outside the submitted work.

TOPLINE:

The remission period of type 1 diabetes (T1D) can be prolonged with high-dose ergocalciferol (a vitamin D analog), by preserving the function of insulin-producing beta cells in newly diagnosed patients.

METHODOLOGY:

• Beta cells may retain approximately 30%-50% function at the time of T1D diagnosis and continue producing insulin for months or years. Preserving beta-cell function early on can extend this remission period and improve long-term glycemic control.
• Researchers conducted a secondary post hoc analysis of a randomized clinical trial looking at residual beta function and vitamin D supplementation in 36 youths (age, 10-21 years; mean age, 13.5 years; 33.3% women) with recently diagnosed T1D.
• Participants were randomly assigned to receive vitamin D (50,000 international units) or placebo every week for 2 months and then biweekly for 10 months.
• Mixed-meal tolerance tests were performed after overnight fasting at 0, 3, 6, 9, and 12 months, and blood draws were obtained 30 minutes and 90 minutes for post-meal C-peptide and glucose estimations.
• The fasting proinsulin to C-peptide ratio (PI:C) and the percentage change in the area under the curve of C-peptide from baseline (%ΔAUC) were calculated to test the effect of vitamin D on beta-cell function.

TAKEAWAY: 

• Vitamin D supplementation improved the insulin secretion capacity of beta cells, as observed by the decrease in the mean fasting PI:C ratio compared with placebo (−0.0009 vs 0.0011; P =.01).
• The reduction in %ΔAUC of C-peptide was notably slower with vitamin D than placebo (−2.8% vs −4.7%; P =.03), indicating a longer delay in the loss of C-peptide.

IN PRACTICE:

“It is exciting to know that vitamin D could protect the beta cells of the pancreas and increase the natural production of good and functional insulin in these patients. This, in turn, prolongs the honeymoon phase of type 1 diabetes and leads to reduced long-term complications of this disease,” Benjamin Udoka Nwosu, MD, Northwell Health, Division of Endocrinology, Department of Pediatrics, Cohen Children’s Medical Center, New Hyde Park, New York, the principal author, said in a press release.

TOPLINE:

Higher dietary niacin intake is associated with a lower risk for all-cause mortality among people with metabolic dysfunction-associated steatotic liver disease (MASLD), but there is no connection between niacin consumption and cardiovascular disease (CVD) mortality, a recent study suggested.

METHODOLOGY:

• Researchers analyzed data from the National Health and Nutrition Examination Survey (2003-2018) for 4315 adults with MASLD (mean age, 52.5 years; 55%, men; 67%, non-Hispanic White).
• Dietary niacin intake levels were based on two 24-hour dietary recall interviews to report the types and quantities of foods that participants consumed in the 24 hours prior to the interviews.
• Participants were categorized by tertile of dietary niacin intake: Tertile 1 (n = 1440), < 18.4 mg; tertile 2 (n = 1441), 18.5-26.6 mg; and tertile 3 (n = 1434), > 26.7 mg.

TAKEAWAY:

• During a median follow-up of 8.8 years, 566 deaths occurred, of which 197 were attributed to CVD.
• Compared with participants with a niacin intake of 18.4 mg or lower (the lowest tertile), the multivariable-adjusted hazard ratios (HRs) for participants with a niacin intake of 26.7 mg or higher (the highest tertile) were 0.70 for all-cause mortality and 0.65 for CVD mortality.
• For the subgroup with diabetes compared with the reference group (the first tertile), the HR of all-cause mortality in the third tertile was 0.82.
• When the subgroup without diabetes was compared with the reference group, the HR of all-cause mortality in the third tertile was 0.58, suggesting a significant interaction between niacin and diabetes with the risk of all-cause mortality.
• An inverse association between dietary niacin intake and all-cause mortality was seen in sensitivity analyses, when excluding a participant who died within 2 years of follow-up.

IN PRACTICE:

“Higher dietary niacin intake was associated with a lower risk of all-cause mortality,” but not CVD, among individuals with MASLD, and “the dose-response association…needs to be further investigated to determine optimal intake level,” the authors wrote.

SOURCE:

The study, led by Jie Pan, MD, Sun Yat-sen University, Guangzhou, China, was published online in JAMA Network Open.

LIMITATIONS:

Physical activity data were missing and could not be adjusted for. The National Death Index used by the researchers has only “modest” ability to accurately classify CVD mortality, and the dietary data were subject to recall bias.

DISCLOSURES:

One author was supported by a grant from the National Nature Science Foundation of China. No other conflicts of interest were reported.

A new position statement from the International Diabetes Federation advises using a 1-hour 75-g oral glucose tolerance test (OGTT) to improve identification of people at risk of developing type 2 diabetes.

“There are many, many people who may appear ‘normal’ if you use A1c or fasting glucose, but if you do a glucose tolerance test, they may have an abnormality after a glucose load. …The 1-hour plasma glucose has been found to be a more sensitive biomarker for the earlier identification of these high-risk individuals,” lead author Michael Bergman, MD, professor of medicine and population health at New York University Grossman School of Medicine, New York City, told this news organization in an interview.

Dr. Bergman presented the document, written by a 22-member international expert panel, on March 6, 2024, at the annual Advanced Technologies & Treatments for Diabetes meeting. It was simultaneously published in Diabetes Research and Clinical Practice.

This is the International Diabetes Federation’s (IDF’s) proposed screening algorithm for “intermediate hyperglycemia” and type 2 diabetes:

• At-risk high-risk individuals are first screened with a validated questionnaire such as the FINDRISK or the American Diabetes Association’s (ADA’s) risk screening tool.
• People identified as high risk should undergo laboratory screening with a 1-hour 75-g OGTT (although a 2-hour OGTT, fasting glucose, or A1c, as currently recommended by several organizations, is still considered acceptable).
• People with a 1-hour plasma glucose value at or above 155 mg (8.6 mmol/L) are considered to have intermediate hyperglycemia and should be prescribed lifestyle intervention and referred to a diabetes prevention program.
• Those with a 1-hour value greater than or equal to 209 mg/dL (11.6 mmol/L) are considered to have type 2 diabetes and should have a repeat test to confirm the diagnosis, with referral for further evaluation and treatment.

The new guidance is based on increasing evidence that the 1-hour test is a better predictor than other tests, including the 2-hour OGTT, of progression to type 2 diabetes and its associated complications, in a variety of populations. The document cites data showing that a plasma glucose of 155 mg/dl or greater on the 1-hour post-75-g test can identify people with undiagnosed type 2 diabetes or who are at increased risk but who have “normal” glucose tolerance as defined by an A1c < 5.7% (38.8 mmol/mol), a fasting plasma glucose < 100 mg/dL (5.6 mmol/L), or a 2-hour value below 140 mg/dL (7.8 mmol/L).

However, even though a 1-hour test may be more convenient than the traditional 2-hour test, incorporating OGTT into busy clinical practice may still pose logistical problems and may not improve ultimate outcomes, Elizabeth Selvin, PhD, MPH, of the Johns Hopkins University Bloomberg School of Public Health, Baltimore, Maryland, told this news organization. “I worry that emphasizing a burdensome test is not going to improve diabetes screening or diabetes prevention. Doing more 1-hour glucose screening is not going to get more people into diabetes prevention programs.”

When an audience member raised the logistics concern during the session Q&A, Dr. Bergman replied, “It’s no different than recommending colonoscopy or a mammogram. … I tell patients that we want to learn more about what is going on before we make a firm diagnosis. … I’ve done more than a hundred 1-hour glucose tolerance tests and have not seen one patient who refused because of inconvenience. Everything depends on the way we discuss things with patients.”
 

Recommendation Based on Emerging Evidence

“Intermediate hyperglycemia” is the World Health Organization’s term to refer to either impaired fasting glucose (IFG) or impaired glucose tolerance (IGT). These conditions are often called “prediabetes,” especially in the United States, but that term has been controversial because not everyone with IFG and IGT will go on to develop type 2 diabetes, said Dr. Bergman, who is also director of the NYU Langone Diabetes Prevention Program.

“With ‘prediabetes’ you’re labeling someone with a disease they may not develop. It’s not normal, but it’s not diabetes, so it’s an intermediate state,” he explained.

The statement provides a detailed summary of the data from 19 studies supporting use of a 1-hour plasma glucose of ≥ 155 mg/dL (8.6 mmol/L) to diagnose intermediate hyperglycemia and type 2 diabetes, including links between that level of glycemia and worsened metabolic and atherogenic profiles, risk for microvascular and macrovascular complications and mortality, and identification of risks for obstructive sleep apnea, cystic fibrosis-related diabetes mellitus, fatty liver disease, and premature mortality.

One major problem with current testing, Dr. Bergman said, is that “there is a huge disconnect between A1c and glucose values. … Only about 30% of individuals with an abnormal A1c will have an abnormal fasting glucose, and the inverse is also true. There’s a big mismatch between the two.”

Current guidelines suggest using both A1c and fasting glucose, but Dr. Bergman said that even then “you’re still missing about 20-30% who have IGT. … Part of the problem is that the criteria we use for defining abnormal fasting and 2-hour levels are too high. … 140 [mg/dL] for the 2-hour is too high and 100 [mg/dL] fasting is too high. … And that’s one of the reasons why many people progress to type 2 diabetes, because we’re using screening thresholds that are nonphysiologic.”

But Dr. Selvin disagrees, pointing to her own work showing that “using a combination of fasting glucose and A1c for screening does an excellent job at identifying high-risk individuals.”

She’s also unconvinced by other data cited in the paper. “I am deeply skeptical about 1-hour glucose being more prognostic than all other glycemic tests. … Associations of glucose tests with incident diabetes are inherently a circular analysis since diabetes is defined by elevations in those same tests. It is helpful to look at progression of diabetes, but these analyses are not simple and doing them well, especially with head-to-head comparisons against different glycemic tests, is hard,” she said.

In her view, “lifestyle interventions and weight loss should be recommended in at-risk individuals, including those with overweight and obesity, hypertension, metabolic syndrome, etc., regardless of 1-hour glucose test results.”

She added, “If we want to prevent diabetes, we need to focus on preventing weight gain and obesity and managing cardiometabolic risk factors. Lifestyle interventions are not effective unless they are intensive and patients are highly adherent. We need to make lifestyle interventions available and affordable for patients. That is the big barrier. I don’t think more screening with 1-hour glucose is going to help.”

Dr. Bergman pointed out that the International Diabetes Federation represents more than 100 countries, including many that are middle- and low-income. “They need a simple, cost-effective tool for screening effectively. A1c is more expensive, and fasting glucose alone will underestimate disease prevalence. So, the IDF felt, after doing a fairly comprehensive due diligence, that the data warranted recommendation of the 1-hour glucose.”

He’s hoping other organizations like the ADA and the World Health Organization will sign on to bring this guidance into the primary care arena. This news organization reached out to ADA for comment, but their representative hadn’t responded by press time.

Dr. Bergman had no disclosures. Dr. Selvin was supported by the National Institutes of Health.

“There are many, many people who may appear ‘normal’ if you use A1c or fasting glucose, but if you do a glucose tolerance test, they may have an abnormality after a glucose load. …The 1-hour plasma glucose has been found to be a more sensitive biomarker for the earlier identification of these high-risk individuals,” lead author Michael Bergman, MD, professor of medicine and population health at New York University Grossman School of Medicine, New York City, told this news organization in an interview.

Dr. Bergman presented the document, written by a 22-member international expert panel, on March 6, 2024, at the annual Advanced Technologies & Treatments for Diabetes meeting. It was simultaneously published in Diabetes Research and Clinical Practice.

This is the International Diabetes Federation’s (IDF’s) proposed screening algorithm for “intermediate hyperglycemia” and type 2 diabetes:

• At-risk high-risk individuals are first screened with a validated questionnaire such as the FINDRISK or the American Diabetes Association’s (ADA’s) risk screening tool.
• People identified as high risk should undergo laboratory screening with a 1-hour 75-g OGTT (although a 2-hour OGTT, fasting glucose, or A1c, as currently recommended by several organizations, is still considered acceptable).
• People with a 1-hour plasma glucose value at or above 155 mg (8.6 mmol/L) are considered to have intermediate hyperglycemia and should be prescribed lifestyle intervention and referred to a diabetes prevention program.
• Those with a 1-hour value greater than or equal to 209 mg/dL (11.6 mmol/L) are considered to have type 2 diabetes and should have a repeat test to confirm the diagnosis, with referral for further evaluation and treatment.

The new guidance is based on increasing evidence that the 1-hour test is a better predictor than other tests, including the 2-hour OGTT, of progression to type 2 diabetes and its associated complications, in a variety of populations. The document cites data showing that a plasma glucose of 155 mg/dl or greater on the 1-hour post-75-g test can identify people with undiagnosed type 2 diabetes or who are at increased risk but who have “normal” glucose tolerance as defined by an A1c < 5.7% (38.8 mmol/mol), a fasting plasma glucose < 100 mg/dL (5.6 mmol/L), or a 2-hour value below 140 mg/dL (7.8 mmol/L).

However, even though a 1-hour test may be more convenient than the traditional 2-hour test, incorporating OGTT into busy clinical practice may still pose logistical problems and may not improve ultimate outcomes, Elizabeth Selvin, PhD, MPH, of the Johns Hopkins University Bloomberg School of Public Health, Baltimore, Maryland, told this news organization. “I worry that emphasizing a burdensome test is not going to improve diabetes screening or diabetes prevention. Doing more 1-hour glucose screening is not going to get more people into diabetes prevention programs.”

When an audience member raised the logistics concern during the session Q&A, Dr. Bergman replied, “It’s no different than recommending colonoscopy or a mammogram. … I tell patients that we want to learn more about what is going on before we make a firm diagnosis. … I’ve done more than a hundred 1-hour glucose tolerance tests and have not seen one patient who refused because of inconvenience. Everything depends on the way we discuss things with patients.”
 

Recommendation Based on Emerging Evidence

“Intermediate hyperglycemia” is the World Health Organization’s term to refer to either impaired fasting glucose (IFG) or impaired glucose tolerance (IGT). These conditions are often called “prediabetes,” especially in the United States, but that term has been controversial because not everyone with IFG and IGT will go on to develop type 2 diabetes, said Dr. Bergman, who is also director of the NYU Langone Diabetes Prevention Program.

“With ‘prediabetes’ you’re labeling someone with a disease they may not develop. It’s not normal, but it’s not diabetes, so it’s an intermediate state,” he explained.

The statement provides a detailed summary of the data from 19 studies supporting use of a 1-hour plasma glucose of ≥ 155 mg/dL (8.6 mmol/L) to diagnose intermediate hyperglycemia and type 2 diabetes, including links between that level of glycemia and worsened metabolic and atherogenic profiles, risk for microvascular and macrovascular complications and mortality, and identification of risks for obstructive sleep apnea, cystic fibrosis-related diabetes mellitus, fatty liver disease, and premature mortality.

One major problem with current testing, Dr. Bergman said, is that “there is a huge disconnect between A1c and glucose values. … Only about 30% of individuals with an abnormal A1c will have an abnormal fasting glucose, and the inverse is also true. There’s a big mismatch between the two.”

Current guidelines suggest using both A1c and fasting glucose, but Dr. Bergman said that even then “you’re still missing about 20-30% who have IGT. … Part of the problem is that the criteria we use for defining abnormal fasting and 2-hour levels are too high. … 140 [mg/dL] for the 2-hour is too high and 100 [mg/dL] fasting is too high. … And that’s one of the reasons why many people progress to type 2 diabetes, because we’re using screening thresholds that are nonphysiologic.”

But Dr. Selvin disagrees, pointing to her own work showing that “using a combination of fasting glucose and A1c for screening does an excellent job at identifying high-risk individuals.”

She’s also unconvinced by other data cited in the paper. “I am deeply skeptical about 1-hour glucose being more prognostic than all other glycemic tests. … Associations of glucose tests with incident diabetes are inherently a circular analysis since diabetes is defined by elevations in those same tests. It is helpful to look at progression of diabetes, but these analyses are not simple and doing them well, especially with head-to-head comparisons against different glycemic tests, is hard,” she said.

In her view, “lifestyle interventions and weight loss should be recommended in at-risk individuals, including those with overweight and obesity, hypertension, metabolic syndrome, etc., regardless of 1-hour glucose test results.”

She added, “If we want to prevent diabetes, we need to focus on preventing weight gain and obesity and managing cardiometabolic risk factors. Lifestyle interventions are not effective unless they are intensive and patients are highly adherent. We need to make lifestyle interventions available and affordable for patients. That is the big barrier. I don’t think more screening with 1-hour glucose is going to help.”

Dr. Bergman pointed out that the International Diabetes Federation represents more than 100 countries, including many that are middle- and low-income. “They need a simple, cost-effective tool for screening effectively. A1c is more expensive, and fasting glucose alone will underestimate disease prevalence. So, the IDF felt, after doing a fairly comprehensive due diligence, that the data warranted recommendation of the 1-hour glucose.”

He’s hoping other organizations like the ADA and the World Health Organization will sign on to bring this guidance into the primary care arena. This news organization reached out to ADA for comment, but their representative hadn’t responded by press time.

TOPLINE:

Patients on weekly glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have high residual gastric content, a major risk factor for aspiration under anesthesia, despite following fasting guidelines before undergoing elective procedures.

METHODOLOGY:

• The increasing use of GLP-1 RAs to manage weight and hyperglycemia has sparked safety concerns because of the drugs’ association with slow gastric emptying, a major risk factor for aspiration under anesthesia.
• This cross-sectional study used gastric ultrasonography to examine the link between GLP-1 RA use and the prevalence of increased residual gastric content.
• All 124 participants (median age, 56 years; 60% women) — half of whom received once-weekly GLP-1 RAs such as semaglutide, dulaglutide, or tirzepatide — adhered to the guideline-recommended fasting duration before undergoing elective procedures under anesthesia.
• The primary outcome focused on identifying increased residual gastric content, defined by the presence of solids, thick liquids, or > 1.5 mL/kg of clear liquids on ultrasound.
• An exploratory analysis examined the association between the duration of GLP-1 RA discontinuation and increased residual gastric content.

TAKEAWAY:

• The adjusted prevalence of increased residual gastric content was 30.5% (95% CI, 9.9%-51.2%) higher in participants who received GLP-1 RA than those who did not.
• Most patients took their last dose of GLP-1 RA within 5 days before their procedure, but elevated residual gastric content persisted even after 7 days of GLP-1 RA discontinuation.
• There was also no significant association between the type of GLP-1 RA used and the prevalence of increased residual gastric content.

IN PRACTICE:

“We expect healthcare professionals will encounter these classes of drugs with increasing frequency in the perioperative period. Perioperative physicians, including anesthesiologists, surgeons, and primary care physicians, should be well-informed about the safety implications of GLP-1 RA drugs,” the authors wrote.

SOURCE:

The study was led by Sudipta Sen, MD, from the Department of Anesthesiology, Critical Care and Pain Medicine, McGovern Medical School, University of Texas Health Center at Houston, Houston, Texas, and published online in JAMA Surgery.

LIMITATIONS:

Residual gastric content, the primary outcome, served as a proxy for aspiration risk and does not have an exact threshold of volume associated with increased risk. The study did not directly evaluate aspiration events. The authors also acknowledged potential bias from unmeasured confounders owing to the observational nature of this study. A small sample size limited the ability to detect a risk difference for each additional day of drug discontinuation before surgery.

DISCLOSURES:

One of the authors reported receiving a grant from the National Institutes of Health. The authors declared no conflicts of interest.

Adults with persistent metabolic syndrome that worsens over time are at increased risk for any type of cancer, according to a new study of more than 44,000 individuals.

The conditions that comprise metabolic syndrome (high blood pressure, high blood sugar, increased abdominal adiposity, and high cholesterol and triglycerides) have been associated with an increased risk of diseases, including heart disease, stroke, and type 2 diabetes, wrote Li Deng, PhD, of Capital Medical University, Beijing, China, and colleagues.

A systematic review and meta-analysis published in Diabetes Care in 2012 showed an association between the presence of metabolic syndrome and an increased risk of various cancers including liver, bladder, pancreatic, breast, and colorectal.

More recently, a 2019 study published in Diabetes showed evidence of increased risk for certain cancers (pancreatic, kidney, uterine, cervical) but no increased risk for cancer overall.

However, the reasons for this association between metabolic syndrome and cancer remain unclear, and the effect of the fluctuating nature of metabolic syndrome over time on long-term cancer risk has not been explored, the researchers wrote.
 

What Does New Study Add to Other Research on Metabolic Syndrome and Cancer Risk?

In the new study, published in Cancer on March 11 (doi: 10.1002/cncr.35235), 44,115 adults in China were separated into four trajectories based on metabolic syndrome scores for the period from 2006 to 2010. The scores were based on clinical evidence of metabolic syndrome, defined using the International Diabetes Federation criteria of central obesity and the presence of at least two other factors including increased triglycerides, decreased HDL cholesterol, high blood pressure (or treatment for previously diagnosed hypertension), and increased fasting plasma glucose (or previous diagnosis of type 2 diabetes).

The average age of the participants was 49 years. The four trajectories of metabolic syndrome were low-stable (10.56% of participants), moderate-low (40.84%), moderate-high (41.46%), and elevated-increasing (7.14%), based on trends from the individuals’ initial physical exams on entering the study.

Over a median follow-up period of 9.4 years (from 2010 to 2021), 2,271 cancer diagnoses were reported in the study population. Those with an elevated-increasing metabolic syndrome trajectory had 1.3 times the risk of any cancer compared with those in the low-stable group. Risk for breast cancer, endometrial cancer, kidney cancer, colorectal cancer, and liver cancer in the highest trajectory group were 2.1, 3.3, 4.5, 2.5, and 1.6 times higher, respectively, compared to the lowest group. The increased risk in the elevated-trajectory group for all cancer types persisted when the low-stable, moderate-low, and moderate-high trajectory pattern groups were combined.

The researchers also examined the impact of chronic inflammation and found that individuals with persistently high metabolic syndrome scores and concurrent chronic inflammation had the highest risks of breast, endometrial, colon, and liver cancer. However, individuals with persistently high metabolic syndrome scores and no concurrent chronic inflammation had the highest risk of kidney cancer.
 

 What Are the Limitations of This Research?

The researchers of the current study acknowledged the lack of information on other causes of cancer, including dietary habits, hepatitis C infection, and Helicobacter pylori infection. Other limitations include the focus only on individuals from a single community of mainly middle-aged men in China that may not generalize to other populations.

Also, the metabolic syndrome trajectories did not change much over time, which may be related to the short 4-year study period.
 

What Is the Takeaway Message for Clinical Practice?

The results suggest that monitoring and managing metabolic syndrome could help reduce cancer risk, the researchers concluded. 

“This research suggests that proactive and continuous management of metabolic syndrome may serve as an essential strategy in preventing cancer,” senior author Han-Ping Shi, MD, PhD, of Capital Medical University in Beijing, said in a press release accompanying the study.

More research is needed to assess the impact of these interventions on cancer risk, he noted. However, the data from the current study can guide future research that may lead to more targeted treatments and more effective preventive strategies, he said in a statement.

The study was supported by the National Key Research and Development Program of China. The researchers had no financial conflicts to disclose.

 What Are the Limitations of This Research?

The researchers of the current study acknowledged the lack of information on other causes of cancer, including dietary habits, hepatitis C infection, and Helicobacter pylori infection. Other limitations include the focus only on individuals from a single community of mainly middle-aged men in China that may not generalize to other populations.

Also, the metabolic syndrome trajectories did not change much over time, which may be related to the short 4-year study period.
 

What Is the Takeaway Message for Clinical Practice?

The results suggest that monitoring and managing metabolic syndrome could help reduce cancer risk, the researchers concluded. 

“This research suggests that proactive and continuous management of metabolic syndrome may serve as an essential strategy in preventing cancer,” senior author Han-Ping Shi, MD, PhD, of Capital Medical University in Beijing, said in a press release accompanying the study.

More research is needed to assess the impact of these interventions on cancer risk, he noted. However, the data from the current study can guide future research that may lead to more targeted treatments and more effective preventive strategies, he said in a statement.

The study was supported by the National Key Research and Development Program of China. The researchers had no financial conflicts to disclose.

Hospital administrators and some department heads have been vocal about the potential for unions to affect both the attending-resident relationship and the ability for residents to directly discuss concerns and educational plans.

Critics feel that having a third party at the table, such as a union representative who isn’t as knowledgeable about the nuances of medical education, could complicate the decision-making process.

Sometimes, there are institution-specific issues as well. One example was at Loma Linda. They argued that unionization would go against their religious principles. They filed a lawsuit. That didn’t go through, and the residents won a few months later.

I know there’s always that one senior, older doctor who says, “Back in our day, we just worked, and we never complained.”

Look at the current situation that residents are facing now, with housing and rent prices and increasing costs of childcare. Sprinkle in some inflation, poor hospital staffing, increasing workload, and add in the fact that the average first-year resident salary in 2023 was around $64,000.

Now, if you look back to 2012, the average salary was around $55,000. If you adjust that for inflation, it would be around $75,000 today, which is more than what the average resident is getting paid.

Then, there are hospital administrators who say that the hospital does not have the money to meet these demands; meanwhile, hospital graduate medical education (GME) offices receive about $150,000 of Medicare funds per resident.

Obviously, there are additional costs when it comes to training and supporting residents. In general, unionizing freaks out the people handling all the cash.

There’s also the threat of a strike, which no hospital wants on their public record. A recent highly publicized event happened at New York’s Elmhurst Hospital, when 160 residents went on strike for 3 days until a deal was made.

Critics of unionizing also cite a particular study in JAMA, which included a survey of 5700 general surgery residents at 285 programs. It found that while unions helped with vacation time and housing stipends, the unions were not associated with improved burnout rates, suicidality, job satisfaction, duty hour violations, mistreatment, educational environment, or salary.

Now, granted, this isn’t the strongest study. It only sampled one group of residents, so I wouldn’t generalize these findings, but it’s still commonly cited by anti-union advocates.

Another potential downside, which is purely anecdotal because I can’t find any data to support this, is potential retaliation against residents or harm to the attending-resident relationship.

I’m an attending. I don’t really understand this one. I don’t exactly own stock in my hospital, nor am I making millions of dollars by siphoning GME money. I’m just trying to focus on educating and supporting my residents the best I can.

TOPLINE:

Exposure to organophosphate ester (OPE) metabolites, a newer group of widely used chemical flame retardants, is linked to a higher risk for thyroid disease, bis(2-chloroethyl) phosphate (BCEP) being the main contributor.

METHODOLOGY:

• Prior studies have reported that OPEs — used in building materials, electronic products, furniture, and textiles — may interfere with thyroid function, hinting at a possible association of OPEs with thyroid disease.
• Researchers assessed the association between OPE exposure and the risk for thyroid disease using data from the 2011-2014 US National Health and Nutrition Examination Survey cycle.
• They included 2449 participants (mean age, 46 years; half of whom were women) who had complete values for seven OPE metabolites through urinalysis and completed questionnaires regarding the presence of thyroid disease.
• The seven OPE metabolites assessed in this study were diphenyl phosphate (DPHP), bis(1,3-dichloro-2-propyl) phosphate, bis(1-chloro-2-propyl) phosphate, BCEP, dibutyl phosphate, dibenzyl phosphate, and 2,3,4,5-tetrabromobenzoic acid.
• Several mixed exposure models were used to investigate the associations between the risk for thyroid disease and exposure to individual and mixed OPEs.

TAKEAWAY:

• A history of thyroid disease was self-reported by 228 participants.
• In one model, the risk for thyroid disease was 57% higher in people in the highest vs the lowest tertile of BCEP exposure (P = .005).
• A newer method confirmed the positive association between exposure to mixed OPE metabolites and a higher risk for thyroid disease (odds ratio, 1.03; P = .013), with BCEP (65%) being the main contributing factor, followed by DPHP (35%).
• A model from another new method showed a J-shaped relationship between the risk for thyroid disease and increasing levels of BCEP exposure, in which the risk first dropped but then rose with increasing exposure.

IN PRACTICE:

“The three models in our study provided similar results, with exposure to mixed OPEs having a tendency to increase the risk of thyroid disease and pointing to BCEP as the most significant compound responsible for this trend,” wrote the authors.

SOURCE:

This study was led by Yuxin Lin, from the Department of Epidemiology and Health Statistics, School of Public Health, Fujian Medical University, Fuzhou, China, and published online in Frontiers in Endocrinology.

LIMITATIONS:

The cross-sectional design cannot establish a causal relationship between OPE exposure and thyroid disease. The study used unweighted data, which could have limited the generalizability of the findings. Moreover, urine sample measurements were performed only once.

DISCLOSURES:

The study was supported by the Fujian Natural Science Foundation Program and the Scientific Research Program of High-level Talents of Fujian Medical University. The authors declared no potential conflicts of interest.

TOPLINE:

The anti-inflammatory shift in mid-pregnancy may be linked to changes in gut microbiota, which, in turn, may wield their influence through fecal and plasma metabolites.

METHODOLOGY:

• Midway through a normal pregnancy, the maternal immune system shifts to a more anti-inflammatory state, which may be linked to changes in the gut microbial community by unknown mechanisms.
• The study explored the associations between the gut microbiota, fecal and plasma metabolites, and cytokine levels of pregnant women and compared them with those of nonpregnant women.
• The study recruited 30 pregnant women (ages 18-34 years; prepregnancy body mass index [BMI], 18.5-21.9) who conceived naturally with a singleton pregnancy and 15 nonpregnant women of similar age and BMI from the First Affiliated Hospital of Jinan University, Guangzhou, China, between February 2019 and August 2020.
• All participants had not used probiotics or antibiotics in the 6 months prior to participating in the study.
• Fecal and blood samples were collected during or after the 37th week of pregnancy in pregnant women until their labor and on the 14th day of the menstrual cycle in nonpregnant women.

TAKEAWAY:

• Pregnant women had more Actinobacteriota than nonpregnant women (9.15% vs 2.98%, respectively; P = .002) in their gut microbiomes, and the most enriched other microbes showed a negative correlation with pro-inflammatory cytokines.
• Pregnant women had differences in 44 fecal and 53 plasma metabolites, with certain enriched metabolites negatively correlated with pro-inflammatory cytokines and certain depleted ones positively correlated.
• Levels of pro-inflammatory plasma cytokines such as interleukins (IL)-1β, IL-2, IL-6, IL-12, interferon gamma, and tumor necrosis factor alpha were reduced, while levels of the anti-inflammatory cytokine IL-4 were elevated in pregnant vs nonpregnant women.
• Researchers identified a total of 46 connections between gut microbes, metabolites, and cytokines, with details suggesting that gut microbes may alter plasma cytokine levels by interacting with host metabolites.

IN PRACTICE:

“Our study revealed complicated associations among gut microbiota, metabolites, and immune system during pregnancy and identified some specific metabolites which may act as mediators between symbiotic microorganisms and immune homeostasis,” the authors wrote.

SOURCE:

The study, led by Ting Huang, Department of Obstetrics and Gynecology, the First Affiliated Hospital of Jinan University, Guangzhou, China, was published online on February 7, 2024, in mSystems.

LIMITATIONS:

The small sample size of the study may have limited capacity to address errors resulting from individual differences. No causal relationships between gut microbiota, metabolites, and immune system response could be confirmed. Researchers were unable to account for the possible effects of confounding variables, such as diet, because of the cross-sectional nature of this study.

DISCLOSURES:

This study was funded by the National Natural Science Foundation of China. The authors declared no conflicts of interest.

Lawmakers have added a provision to raise Medicare payments to clinicians to a $460 billion bipartisan package of federal spending bills that passed in the House on March 6 and is expected to be passed in the Senate and signed by President Biden before then end of March 8, but industry groups have criticized it as paltry.

Lawmakers often tweak Medicare policy by adding provisions to other kinds of legislation, including the spending bills Congress must pass to keep the federal government running.

Physicians’ groups and some lawmakers have long pressed Congress to change Medicare payment rules with little success, even as inflation has caused physicians’ expenses to rise. Doctors now face a 3.4% cut to Medicare reimbursements in 2024, which would be only partly mitigated by the recently announced provision.

The Medical Group Management Association (MGMA) said the proposed increase would total 1.68%. The increase, part of a bipartisan package of bills released by the House and Senate Appropriations committees on March 3, would apply to the budget for fiscal 2024, which began on October 1, 2023.

“We are deeply disappointed with Congress’ half-hearted attempt to remedy the devastating blow physician practices were dealt by the 2024 Medicare Physician Fee Schedule,” Anders Gilberg, senior vice president of MGMA, said in a statement. “Anything less than a full reversal of the 3.4% cut is appallingly inadequate.”

The American Medical Association said it was “extremely disappointed” that the boost only eased, but did not fully reverse, a deeper planned cut.

The American Academy of Family Physicians (AAFP) also expressed disappointment with the proposed increase.

“The AAFP has repeatedly told Congress that the 3.4% Medicare payment reduction that went into effect on January 1 is untenable for family physicians and threatens patients’ access to primary care,” the group said in a statement.

“While we appreciate the partial relief, family physicians continue to face an annual threat of payment cuts that are detrimental to practices and patients,” AAFP said.
