Study Reveals Sugar Amplifies Antibiotic Damage to Gut Microbiome in Cancer Patients

Study Reveals Sugar Amplifies Antibiotic Damage to Gut Microbiome in Cancer Patients

A new study, led by researchers from NYU Langone Health, City of Hope, and Memorial Sloan Kettering, indicates that consuming sweets while taking antibiotics can worsen the damage these drugs inflict on the gut's bacterial community. The research, published in the journal Nature, tracked the dietary intake of 173 hospitalized cancer patients, analyzing over 9,000 meals and daily gut microbiome samples. It found that for every 100 grams of sugar consumed in the 48 hours before antibiotic treatment, there was an additional 21% reduction in alpha diversity, a measure of beneficial bacterial species. This combination of a sugary diet and antibiotics also led to a proliferation of harmful bacterial species like Enterococcus faecium, which is associated with difficult-to-treat infections. Experiments in mice corroborated these findings, showing a significant increase in Enterococcus populations when exposed to antibiotics and dietary sucrose. The study highlights the vulnerability of the gut microbiome, especial...

Sugar-Rich Diets Exacerbate Antibiotic-Induced Gut Microbiome Disruption, Study Finds

Sugar-Rich Diets Exacerbate Antibiotic-Induced Gut Microbiome Disruption, Study Finds

A study published in Nature reveals that sugar-rich foods can worsen the disruption of the gut microbiome caused by antibiotics. The research, conducted on adult allo-HCT recipients at Memorial Sloan Kettering Cancer Center in New York between 2017 and 2022, involved monitoring dietary intake and microbiome changes. Patients were asked to record their consumption of each meal item, and this data was linked to detailed food classifications. The study found that the interaction between sugar intake and antibiotic exposure significantly impacted microbial diversity. Specifically, a 100g increase in 'sweets' (dehydrated weight) exacerbated the negative effects of antibiotics on the gut microbiome. This finding was consistent across different conditioning intensities for transplant patients.

NYU Langone Health Study Reveals Sugar Amplifies Antibiotic Damage to Gut Microbiome

A new study led by researchers from NYU Langone Health, City of Hope, and Memorial Sloan Kettering has found that consuming sugar while taking antibiotics can worsen the damage to the gut's bacterial community. The research, published in the journal Nature, tracked the diets of 173 hospitalized cancer patients, analyzing 9,419 meals and their corresponding gut microbiome changes. The study observed an additional 21% reduction in alpha diversity, a measure of beneficial bacterial species variety, for every 100 grams of sugar consumed within 48 hours before antibiotic treatment. This combination of a sugary diet and antibiotics was also linked to an increase in harmful bacterial species like Enterococcus faecium, which is associated with difficult-to-treat infections. Experiments in mice further confirmed this pattern, showing a significant increase in Enterococcus populations when exposed to antibiotics and dietary sucrose.

City of Hope Study Links Sugar Consumption During Antibiotic Treatment to Gut Microbiome Disruption

City of Hope Study Links Sugar Consumption During Antibiotic Treatment to Gut Microbiome Disruption

A new study conducted by researchers at City of Hope suggests that consuming less sugar during antibiotic treatment may help protect the gut microbiome. The study, published in 'Nature', followed blood cancer patients undergoing allogeneic hematopoietic cell transplant, a population highly susceptible to severe gut microbiome disruption. Researchers analyzed over 9,400 meals and 1,000 stool samples from 173 hospitalized patients, linking sugar-rich foods to greater antibiotic-related microbiome disruption. Co-senior author Marcel van den Brink, M.D., Ph.D., stated that antibiotics disrupt the diversity of gut bacteria, which are crucial for immune system support. The study found that patients who consumed more sweets while taking antibiotics experienced a significant loss of microbiome diversity, with aggressive microbes like Enterococcus crowding out other bacterial strains. This effect was particularly pronounced with broad-spectrum antibiotics and high-sugar intake, leading to a 24% drop in bacterial di...

Dietary Sugar Intake Linked to Gut Microbiome Disruption During Antibiotic Treatment in Cancer Patients

Dietary Sugar Intake Linked to Gut Microbiome Disruption During Antibiotic Treatment in Cancer Patients

A study conducted by Jonathan Peled at the Memorial Sloan Kettering Cancer Center in New York and his colleagues has revealed that consuming high-sugar foods while taking antibiotics can significantly reduce the diversity of the gut microbiome. The research, involving 158 blood cancer patients undergoing chemotherapy and antibiotic treatment, meticulously tracked dietary intake and changes in gut bacteria. The findings indicate that for every 100-gram increase in high-sugar food or drink consumption during antibiotic treatment, the drop in total bacterial diversity was, on average, 24% greater. This combination also led to an increase in potentially pathogenic bacteria, such as Enterococcus faecium, which can cause hospital-acquired infections. The study suggests that antibiotics disrupt the gut's bacterial balance, and sugar acts as 'rocket fuel' for the remaining, often less beneficial, strains.

Study Finds No Increase in Drug Launch Prices Following IRA Medicare Negotiation Implementation

Study Finds No Increase in Drug Launch Prices Following IRA Medicare Negotiation Implementation

A recent study by Harvard-affiliated researchers, including Benjamin H. Rome, M.D., M.P.H., indicates that the Inflation Reduction Act (IRA) and its provision for Medicare drug price negotiation have not led to an increase in drug launch prices. Prior to the IRA, drug launch prices, specifically wholesale acquisition cost (WAC) prices, increased by an average of 7.82% per year. Following the implementation of the IRA, the study identified a trend change of -3.71%. While this figure suggests a potential decrease in the rate of price increases, Rome noted that the wide confidence interval around this nominal figure makes its statistical significance questionable. This research challenges earlier concerns from commentators, such as Avalere Health’s Laura Housman, Dr. P.H., M.P.H., MBA, who speculated that drugmakers might increase initial launch prices to offset leaner margins resulting from Medicare's new pricing power. The findings align with previous research from Vanderbilt’s Stacie B. Dusetzina, which al...

UNC Charlotte Professor Co-Authors Landmark Bat Genome Study Revealing 65-Million-Year Origins

UNC Charlotte Professor Co-Authors Landmark Bat Genome Study Revealing 65-Million-Year Origins

Laurel Yohe, Ph.D., an assistant professor of bioinformatics at The University of North Carolina at Charlotte, is a co-author of a significant bat genome study published in Nature. This study, the largest combined bat genome and fossil analysis ever conducted, was led by the international Bat1K consortium, involving 137 researchers from 64 countries. The research integrated 103 bat genomes, representing all 21 recognized bat families, with 44 fossil specimens. The Bat1K consortium aims to sequence the genomes of over 1,400 living bat species, and this paper marks substantial progress toward that goal. The findings indicate that bats originated in Europe approximately 65 million years ago before spreading globally, and they also shed light on the evolution of echolocation and powered flight, suggesting these traits co-evolved earlier than previously believed.

Canton Police Chief Raises Alarm Over Unregulated Kratom Derivative 7-OH

Canton Police Chief Raises Alarm Over Unregulated Kratom Derivative 7-OH

Canton Police Chief Joseph Bialy has issued a warning regarding 7-OH, a synthetic derivative of kratom, highlighting its unregulated sale and potential health risks. Unlike regulated substances such as alcohol, tobacco, and cannabis, kratom and its derivatives are largely unregulated, leading to concerns about product consistency and safety. Chief Bialy noted that labels on these products often do not accurately reflect their chemical compounds. The synthetic derivative 7-OH is particularly concerning as it can mimic the effects of heroin and is easily accessible. The Canton Township board recently approved an ordinance, the Kratom and Unsafe Psychoactive Substance Regulation, to address these issues. This new regulation aims to control the sale of kratom, ban synthetic products, and prohibit sales to individuals under 21 years of age. The state's agricultural department is collaborating with local police agencies to investigate these products, many of which are imported from overseas and marketed as food ...

Columbia University Irving Medical Center Rallies on Capitol Hill Against Proposed NIH Funding Cuts

Columbia University Irving Medical Center Rallies on Capitol Hill Against Proposed NIH Funding Cuts

The Columbia University Irving Medical Center (CUIMC) recently organized a rally on Capitol Hill to advocate for sustained and increased funding for the National Institutes of Health (NIH). This comes in response to the President’s budget request for the 2027 federal fiscal year, which proposes a 12% cut to NIH funding. A contingent of 15 students, faculty, and staff from various schools within Columbia, including VP&S, School of Nursing, Teachers College, and School of Social Work, met with staff from the New York and New Jersey Congressional delegations. Ross Frommer, vice president of government affairs at CUIMC, emphasized the importance of educating policymakers about the role of NIH-funded research in medical innovation. This year's rally, held on September 17, brought together over 300 participants from more than 40 states, marking it as the second-largest rally since the event's inception in 2013, which was also initiated in response to threatened NIH budget cuts. Last year, a proposed 40% NIH budg...

U.S. Study Reveals High Nutritional Deficiency Rates in Children on GLP-1 Medicines for Diabetes and Obesity

U.S. Study Reveals High Nutritional Deficiency Rates in Children on GLP-1 Medicines for Diabetes and Obesity

A recent U.S. study has found that approximately one in six children and teenagers (16.8%) prescribed GLP-1 receptor agonists for type 2 diabetes, severe obesity, or related metabolic conditions developed a nutritional deficiency or related complication within a year of starting treatment. The study analyzed insurance records of 2,031 young individuals aged 10 to 17 who began GLP-1 treatment between 2017 and 2022. Before starting the medication, none of these participants had a recorded nutritional deficiency. Within six months, 10.2% had been diagnosed with at least one deficiency, a figure that rose to 16.8% by the one-year mark. Vitamin D deficiency was the most common issue, affecting 12.4% of the group, followed by nutritional anemia (1.6%), iron-deficiency anemia (1.4%), and muscle loss (0.8%). The research also highlighted a significant gap in nutritional support, with only 5.8% receiving a nutrition consultation within 30 days of starting treatment, and only 23.3% by six months.

UTHealth Houston Researchers Utilize Claims Database to Enhance Long COVID Surveillance

UTHealth Houston Researchers Utilize Claims Database to Enhance Long COVID Surveillance

Researchers at UTHealth Houston have leveraged the Texas All-Payer Claims Database (TX-APCD) to analyze patterns in long COVID diagnoses across various populations and SARS-CoV-2 variant periods from October 2021 to October 2023. This initiative aims to address the existing gap in comprehensive surveillance systems for long COVID, which, unlike acute COVID-19, lacks a dedicated tracking mechanism. The study, published in the International Journal of Infectious Diseases, found that long COVID diagnoses generally followed waves of acute COVID-19 infection, with peaks in emergency department visits preceding increases in long COVID claims by two to three weeks. Key findings indicate that older adults, particularly those 70 and older, and Medicare fee-for-service beneficiaries had substantially higher documented rates of long COVID. Women also showed higher rates than men. Geographic disparities were observed, with higher documented long COVID incidence in parts of the High Plains and Northwest Texas regions, ...

Study Links Irregular Weekend Meal Times to Increased Heart Disease Risk in Men

Study Links Irregular Weekend Meal Times to Increased Heart Disease Risk in Men

A new study conducted by research teams from France and Spain has found a correlation between variations in meal times between weekdays and weekends and an increased risk of cardiovascular disease in men. The study analyzed data from 104,806 adults over an average of 8.1 years, tracking their meal times and health status. Participants were categorized into groups based on how much their meal time midpoint shifted between weekdays and weekends. The findings indicate that for every one-hour shift in the midpoint of meal times, the overall incidence of cardiovascular disease in men increased by 14%, and specifically, coronary artery disease incidence rose by 21%. This association remained consistent even after accounting for factors like changes in sleep patterns and dietary quality. The study suggests that disruptions to the natural circadian rhythm, caused by inconsistent meal times, may place additional stress on the heart. The same correlation was not observed in women, which researchers believe may be du...
