The peer-review process, which is used by scientific journals to validate legitimate research, is now under legal scrutiny. The US District Court for the Southern District of New York will soon rule on whether scientific publishers have compromised this system for profit. In mid-September, University of California, Los Angeles neuroscientist Lucina Uddin filed a class action lawsuit against six leading academic publishers — Elsevier, Wolters Kluwer, Wiley, Sage Publications, Taylor & Francis, and Springer Nature — accusing them of violating antitrust laws and obstructing academic research.

The lawsuit targets several long-standing practices in scientific publishing, including the lack of compensation for peer reviewers, restrictions that require submitting to only one journal at a time, and bans on sharing manuscripts under review. Uddin’s complaint argues that these practices contribute to inefficiencies in the review process, thus delaying the publication of critical discoveries, which could hinder research, clinical advancements, and the development of new medical treatments.

The suit also noted that these publishers generated $10 billion in revenue in 2023 in peer-reviewed journals. However, the complaint seemingly overlooks the widespread practice of preprint repositories, where many manuscripts are shared while awaiting peer review.
 

Flawed Reviews

A growing number of studies have highlighted subpar or unethical behaviors among reviewers, who are supposed to adhere to the highest standards of methodological rigor, both in conducting research and reviewing work for journals. One recent study published in Scientometrics in August examined 263 reviews from 37 journals across various disciplines and found alarming patterns of duplication. Many of the reviews contained identical or highly similar language. Some reviewers were found to be suggesting that the authors expand their bibliographies to include the reviewers’ own work, thus inflating their citation counts.

As María Ángeles Oviedo-García from the University of Seville in Spain, pointed out: “The analysis of 263 review reports shows a pattern of vague, repetitive statements — often identical or very similar — along with coercive citations, ultimately resulting in misleading reviews.”

Experts in research integrity and ethics argue that while issues persist, the integrity of scientific research is improving. Increasing research and public disclosure reflect a heightened awareness of problems long overlooked.

“There is indeed a problem with research reliability, but it’s not as widespread or severe as some portray,” said Daniele Fanelli, a metascientist at the London School of Economics and Political Science in England. Speaking to this news organization, Fanelli, who has been studying scientific misconduct for about 20 years, noted that while his early work left him disillusioned, further research has replaced his cynicism with what he describes as healthy skepticism and a more optimistic outlook. Fanelli also collaborates with the Luxembourg Agency for Research Integrity and the Advisory Committee on Research Ethics and Bioethics at the Italian National Research Council (CNR), where he helped develop the first research integrity guidelines.
 

Lack of Awareness

A recurring challenge is the difficulty in distinguishing between honest mistakes and intentional misconduct. “This is why greater investment in education is essential,” said Daniel Pizzolato, European Network of Research Ethics Committees, Bonn, Germany, and the Centre for Biomedical Ethics and Law, KU Leuven in Belgium.

While Pizzolato acknowledged that institutions such as the CNR in Italy provide a positive example, awareness of research integrity is generally still lacking across much of Europe, and there are few offices dedicated to promoting research integrity. However, he pointed to promising developments in other countries. “In France and Denmark, researchers are required to be familiar with integrity norms because codes of conduct have legal standing. Some major international funding bodies like the European Molecular Biology Organization are making participation in research integrity courses a condition for receiving grants.”

Pizzolato remains optimistic. “There is a growing willingness to move past this impasse,” he said.

A recent study published in The Journal of Clinical Epidemiology reveals troubling gaps in how retracted biomedical articles are flagged and cited. Led by Caitlin Bakkera, Department of Epidemiology, Maastricht University, Maastricht, the Netherlands, the research sought to determine whether articles retracted because of errors or fraud were properly flagged across various databases.

The results were concerning: Less than 5% of retracted articles had consistent retraction notices across all databases that hosted them, and less than 50% of citations referenced the retraction. None of the 414 retraction notices analyzed met best-practice guidelines for completeness. Bakkera and colleagues warned that these shortcomings threaten the integrity of public health research.
 

Fanelli’s Perspective

Despite the concerns, Fanelli remains calm. “Science is based on debate and a perspective called organized skepticism, which helps reveal the truth,” he explained. “While there is often excessive skepticism today, the overall quality of clinical trials is improving.

“It’s important to remember that reliable results take time and shouldn’t depend on the outcome of a single study. It’s essential to consider the broader context, the history of the research field, and potential conflicts of interest, both financial and otherwise. Biomedical research requires constant updates,” he concluded.

TOPLINE:

Metformin use in adults with type 2 diabetes (T2D) is associated with a slightly lower incidence of long COVID and death within 180 days after SARS-CoV-2 infection.

METHODOLOGY:

• Previous studies have shown that metformin use before and during SARS-CoV-2 infection reduces severe COVID-19 and postacute sequelae of SARS-CoV-2 (PASC), also referred to as long COVID, in adults.
• A retrospective cohort analysis was conducted to evaluate the association between metformin use before and during SARS-CoV-2 infection and the subsequent incidence of PASC.
• Researchers used data from the National COVID Cohort Collaborative (N3C) and National Patient-Centered Clinical Research Network (PCORnet) electronic health record (EHR) databases to identify adults (age, ≥ 21 years) with T2D prescribed a diabetes medication within the past 12 months.
• Participants were categorized into those using metformin (metformin group) and those using other noninsulin diabetes medications such as sulfonylureas, dipeptidyl peptidase-4 inhibitors, or thiazolidinediones (the comparator group); those who used glucagon-like peptide 1 receptor agonists or sodium-glucose cotransporter-2 inhibitors were excluded.
• The primary outcome was the incidence of PASC or death within 180 days after SARS-CoV-2 infection, defined using International Classification of Diseases U09.9 diagnosis code and/or computable phenotype defined by a predicted probability of > 75% for PASC using a machine learning model trained on patients diagnosed using U09.9 (PASC computable phenotype).

TAKEAWAY:

• Researchers identified 51,385 and 37,947 participants from the N3C and PCORnet datasets, respectively.
• Metformin use was associated with a 21% lower risk for death or PASC using the U09.9 diagnosis code (P < .001) and a 15% lower risk using the PASC computable phenotype (P < .001) in the N3C dataset than non-metformin use.
• In the PCORnet dataset, the risk for death or PASC was 13% lower using the U09.9 diagnosis code (P = .08) with metformin use vs non-metformin use, whereas the risk did not differ significantly between the groups when using the PASC computable phenotype (P = .58).
• The incidence of PASC using the U09.9 diagnosis code for the metformin and comparator groups was similar between the two datasets (1.6% and 2.0% in N3C and 2.2 and 2.6% in PCORnet, respectively).
• However, when using the computable phenotype, the incidence rates of PASC for the metformin and comparator groups were 4.8% and 5.2% in N3C and 25.2% and 24.2% in PCORnet, respectively.

IN PRACTICE:

“The incidence of PASC was lower when defined by [International Classification of Diseases] code, compared with a computable phenotype in both databases,” the authors wrote. “This may reflect the challenges of clinical care for adults needing chronic medication management and the likelihood of those adults receiving a formal PASC diagnosis.” 

SOURCE:

The study was led by Steven G. Johnson, PhD, Institute for Health Informatics, University of Minnesota, Minneapolis. It was published online in Diabetes Care.

LIMITATIONS:

The use of EHR data had several limitations, including the inability to examine a dose-dependent relationship and the lack of information on whether medications were taken before, during, or after the acute infection. The outcome definition involved the need for a medical encounter and, thus, may not capture data on all patients experiencing symptoms of PASC. The analysis focused on the prevalent use of chronic medications, limiting the assessment of initiating metformin in those diagnosed with COVID-19.

DISCLOSURES:

The study was supported by the National Institutes of Health Agreement as part of the RECOVER research program. One author reported receiving salary support from the Center for Pharmacoepidemiology and owning stock options in various pharmaceutical and biopharmaceutical companies. Another author reported receiving grant support and consulting contracts, being involved in expert witness engagement, and owning stock options in various pharmaceutical, biopharmaceutical, diabetes management, and medical device companies.

BOSTON — Gastroesophageal reflux disease (GERD) is associated with better in-hospital outcomes for patients hospitalized with chronic obstructive pulmonary disease (COPD). The finding is a surprise, considering that GERD has been associated with more COPD exacerbations. GERD is also more common among patients with COPD than in the general population.

“It was a very surprising result. We double-checked the analysis once we got it the first time because the whole expectation was that the outcomes will be worse. But because it’s a retrospective study and it’s based on a national database, there are some limitations,” said ABM Nasibul Alam, MD, who presented the study at the annual meeting of the American College of Chest Physicians (CHEST) . Alam is an internal medicine resident at Northwestern Medicine McHenry Hospital, McHenry, Illinois.

One possible conclusion is that acid reflux therapies received in hospital may be benefitting COPD. The retrospective nature of the study precludes establishing a causal relationship, but there are possible mechanisms that could account for a benefit, according to Alam.

“They might prevent micro-aspirations or silent aspirations in COPD patients. Sometimes you may not have a clinical diagnosis of GERD, but the patient might have silent micro-aspirations, so it might contribute to decreasing that,” said Alam.

The study was conducted to fill a gap in the literature. “Some studies have shown that the lung function in COPD patients gets moderately decreased if they have coexisting GERD, but there aren’t any studies that have looked into how it impacts COPD patients when they’re hospitalized, and especially acute complications,” said Alam.

The researchers retrospectively analyzed data from the Nationwide Readmissions Database from 2017 to 2020, utilizing ICD-10 codes to identify 3,798,952 hospitalized adults with a primary diagnosis of COPD, of which 26.97% also had GERD. Individuals without GERD were more likely to be male (47.72% vs 39.88%).

After multivariate adjustment, the presence of GERD was associated with a lower mortality rate (adjusted odds ratio [aOR], 0.717; P < .001) and reduced risks for acute respiratory failure (aOR, 0.915; P < .001), need for noninvasive mechanical ventilation (aOR, 0.907; P < .001), need for invasive ventilation for 24 hours or more (aOR, 0.727; P < .001), acute kidney injury (aOR, 0.877; P < .001), septic shock (aOR, 0.731; ^P < .001), and acute heart failure (aOR, 0.762; P < .001).

Despite these improved in-hospital outcomes, the researchers found that patients with GERD were at a higher risk for 30-day readmission (aOR, 1.08; P < .001). They also had slightly longer lengths of stay (+0.09 day; P < .001) and lower total charges (−$2824.5996; P < .001).

There have also been studies suggesting that GERD can directly lead to worse lung function among patients with COPD. “So it will be interesting to see if these medications have some kind of impact on the lung function as well. We need more robust studies [to determine that],” said Alam.

It is also important to keep in mind the long-term risk of proton pump inhibitors, especially in older patients. “We have to have good data before we start recommending this,” said Alam.

He suggested that physicians should begin to think more holistically about COPD management and consider the comorbidities. Alam has studied vitamin B12 deficiency in patients with COPD and found an association with cardiovascular comorbidities. “There are so many comorbidities with COPD. COPD itself puts patients at risk of cardiovascular comorbidity, for example. So when we have patients with COPD, we have to think about all those comorbidities and have to manage the patients comprehensively rather than just focusing on the specific targeted interventions,” said Alam.

The study should encourage further research, according to Kunal Deokar, MD, who moderated the session where the study was presented. “It does give us a signal that probably we should have more studies to look into whether patients hospitalized for COPD with GERD really have lower mortality rates, and what will be the effect of treatment on these patients,” said Deokar, who is an assistant professor of pulmonary medicine at the All India Institute of Medical Sciences, Delhi, India.

Alam and Deokar disclosed no relevant financial relationships.

There have also been studies suggesting that GERD can directly lead to worse lung function among patients with COPD. “So it will be interesting to see if these medications have some kind of impact on the lung function as well. We need more robust studies [to determine that],” said Alam.

It is also important to keep in mind the long-term risk of proton pump inhibitors, especially in older patients. “We have to have good data before we start recommending this,” said Alam.

He suggested that physicians should begin to think more holistically about COPD management and consider the comorbidities. Alam has studied vitamin B12 deficiency in patients with COPD and found an association with cardiovascular comorbidities. “There are so many comorbidities with COPD. COPD itself puts patients at risk of cardiovascular comorbidity, for example. So when we have patients with COPD, we have to think about all those comorbidities and have to manage the patients comprehensively rather than just focusing on the specific targeted interventions,” said Alam.

The study should encourage further research, according to Kunal Deokar, MD, who moderated the session where the study was presented. “It does give us a signal that probably we should have more studies to look into whether patients hospitalized for COPD with GERD really have lower mortality rates, and what will be the effect of treatment on these patients,” said Deokar, who is an assistant professor of pulmonary medicine at the All India Institute of Medical Sciences, Delhi, India.

BOSTON — Gastroesophageal reflux disease (GERD) is associated with better in-hospital outcomes for patients hospitalized with chronic obstructive pulmonary disease (COPD). The finding is a surprise, considering that GERD has been associated with more COPD exacerbations. GERD is also more common among patients with COPD than in the general population.

“It was a very surprising result. We double-checked the analysis once we got it the first time because the whole expectation was that the outcomes will be worse. But because it’s a retrospective study and it’s based on a national database, there are some limitations,” said ABM Nasibul Alam, MD, who presented the study at the annual meeting of the American College of Chest Physicians (CHEST) . Alam is an internal medicine resident at Northwestern Medicine McHenry Hospital, McHenry, Illinois.

One possible conclusion is that acid reflux therapies received in hospital may be benefitting COPD. The retrospective nature of the study precludes establishing a causal relationship, but there are possible mechanisms that could account for a benefit, according to Alam.

“They might prevent micro-aspirations or silent aspirations in COPD patients. Sometimes you may not have a clinical diagnosis of GERD, but the patient might have silent micro-aspirations, so it might contribute to decreasing that,” said Alam.

The study was conducted to fill a gap in the literature. “Some studies have shown that the lung function in COPD patients gets moderately decreased if they have coexisting GERD, but there aren’t any studies that have looked into how it impacts COPD patients when they’re hospitalized, and especially acute complications,” said Alam.

The researchers retrospectively analyzed data from the Nationwide Readmissions Database from 2017 to 2020, utilizing ICD-10 codes to identify 3,798,952 hospitalized adults with a primary diagnosis of COPD, of which 26.97% also had GERD. Individuals without GERD were more likely to be male (47.72% vs 39.88%).

After multivariate adjustment, the presence of GERD was associated with a lower mortality rate (adjusted odds ratio [aOR], 0.717; P < .001) and reduced risks for acute respiratory failure (aOR, 0.915; P < .001), need for noninvasive mechanical ventilation (aOR, 0.907; P < .001), need for invasive ventilation for 24 hours or more (aOR, 0.727; P < .001), acute kidney injury (aOR, 0.877; P < .001), septic shock (aOR, 0.731; ^P < .001), and acute heart failure (aOR, 0.762; P < .001).

Despite these improved in-hospital outcomes, the researchers found that patients with GERD were at a higher risk for 30-day readmission (aOR, 1.08; P < .001). They also had slightly longer lengths of stay (+0.09 day; P < .001) and lower total charges (−$2824.5996; P < .001).

TOPLINE:

Gestational supplementation of 1000 IU/d cholecalciferol (vitamin D3) from early pregnancy until delivery increases the bone mineral content, bone mineral density (BMD), and bone mineral apparent density in children at age 6-7 years.

METHODOLOGY:

• The double-blinded, placebo-controlled MAVIDOS trial of gestational vitamin D supplementation previously showed increased BMD at age 4 years (but no difference at birth), and it is unclear how the effect may persist or change over time.
• In the original trial, researchers randomized 1134 pregnant women with singleton pregnancy from three UK hospitals from 2008 to 2014, and the 723 children born to mothers recruited in Southampton were invited to continue in offspring follow-up.
• Mothers were randomly assigned to receive either 1000-IU/d vitamin D or placebo from 14-17 weeks’ gestation until delivery; women in the placebo arm could take up to 400-IU/d vitamin D.
• In this post hoc analysis, among 454 children who were followed up at age 6-7 years, 447 had a usable whole body and lumbar spine dual-energy x-ray absorptiometry scan (placebo group: n = 216; 48% boys; 98% White mothers and vitamin D group: n = 231; 56% boys; 96% White mothers).
• Offspring follow-up measures at birth and 4 and 6-7 years were bone area, bone mineral content, BMD, and bone mineral apparent density, derived from a dual-energy x-ray absorptiometry scan of whole body less head (WBLH), as well as fat and lean mass.

TAKEAWAY:

• The effect of gestational vitamin D supplementation on bone outcomes in children was similar at ages 4 and 6-7 years.
• At age 6-7 years, gestational vitamin D supplementation resulted in higher WBLH bone mineral content (0.15 SD; 95% CI, 0.04-0.26) and BMD (0.18 SD; 95% CI, 0.06-0.31) than placebo.
• The WBLH bone mineral apparent density (0.18 SD; 95% CI, 0.04-0.32) was also higher in the vitamin D group.
• The lean mass was greater in the vitamin D group (0.09 SD; 95% CI, 0.00-0.17) than in the placebo group.

IN PRACTICE:

“These findings suggest that pregnancy vitamin D supplementation may be an important population health strategy to improve bone health,” the authors wrote.

SOURCE:

This study was led by Rebecca J. Moon, PhD, MRC Lifecourse Epidemiology Centre, University of Southampton, Southampton General Hospital, England. It was published online in The American Journal of Clinical Nutrition.

LIMITATIONS: 

Only individuals with baseline vitamin D levels of 25-100 nmol/L were eligible, excluding those with severe deficiency who might have benefited the most from supplementation. The participants were mostly White and well-educated, commonly overweight, which may have limited generalizability to other populations. Only 47% of the original cohort participated in the follow-up phase. Differences in maternal age, smoking status, and education between participants who remained in the study and those who did not may have introduced bias and affected generalizability.

DISCLOSURES:

The study was supported by Versus Arthritis UK, Medical Research Council, Bupa Foundation, and National Institute for Health and Care Research, Southampton Biomedical Research Centre, and other sources. Some authors disclosed receiving travel reimbursement, speaker or lecture fees, honoraria, research funding, or personal or consultancy fees from Alliance for Better Bone Health and various pharmaceutical, biotechnology, medical device, healthcare, and food and nutrition companies outside the submitted work.

Breast cancer incidence has been on the rise, particularly among White women under age 50, but breast cancer deaths — for some, but not all, populations — have been steadily decreasing, according to a biennial update from the American Cancer Society (ACS).

The ACS update, which underscores the persistence of racial and ethnic disparities in breast cancer incidence and outcomes, noted an overall 1% annual increase in breast cancer incidence from 2012 to 2021. The additional cases were largely composed of localized-stage and hormone receptor (HR)–positive disease, which generally have better prognoses than more advanced and HR–negative disease.

Deaths from breast cancer, however, declined from 1989 to 2022, with an overall drop of 44%. That percentage drop “translates to almost 518,000 fewer women dying from breast cancer in the United States during this time,” Angela N. Giaquinto and ACS colleagues noted in the report, published in CA: A Cancer Journal for Clinicians.

“This progress is the result of advances in treatment and earlier detection through screening,” the authors wrote, while stressing that “these interventions have not been disseminated equally.”

The ACS also published an educational companion — Breast Cancer Facts & Figures 2024-2025 — that provides additional insights about trends in breast cancer and steps needed to bolster prevention, detection, and treatment advances.
 

Incidence and Mortality

Although the overall annual increase in breast cancer incidence from 2012 to 2021 was 1%, the increase was steeper among women under age 50, at 1.4% annually vs 0.7% among those aged 50 or older.

Asian American/Pacific Islander women had the greatest increases in breast cancer incidence among both age groups, with a 2.7% annual increase for those aged under 50 and a 2.5% increase for those aged 50 or older. This group, however, had the second lowest breast cancer rate in 2000 at 57.4 cases per 100,000 persons, but the highest rate in 2021 at 86.3 cases per 100,000, alongside White women (86.4 cases per 100,000). Black women were not far behind at 81.5 cases per 100,000.

Black women were least likely to be diagnosed with localized-stage breast cancer and most likely to be diagnosed with distant-stage or unstaged cancer, with American Indian/Alaska Native women not far behind.

Despite the rising incidence of breast cancer, death rates from the disease have gone down considerably overall from about 33 deaths per 100,000 women in 1989 to 19 deaths per 100,000 in 2022.

However, not all women have experienced these survival gains equally, Ms. Giaquinto and colleagues noted.

Since 1990, the mortality rate has remained unchanged among American Indian/Alaska Native women. Black women, however, have experienced a 38% higher mortality rate than White women, despite having a 5% lower incidence of breast cancer.

In fact, Black women have the lowest survival of any racial and ethnic group for every breast cancer subtype and stage of disease except localized disease.

Additional key findings from the report:

• In 2024, an estimated 310,720 new invasive breast cancers and 56,500 cases of ductal carcinoma in situ will be diagnosed among women in the United States, and an additional 2790 cases will be diagnosed in men.
• On the mortality front, in 2024, approximately 42,250 women are expected to die of breast cancer; 530 breast cancer deaths are anticipated in men.
• As for the lifetime risk for breast cancer, approximately one in eight women in the United States (13.1%) will be diagnosed with invasive breast cancer; 1 in 43 (2.3%) will die from the disease.
• The 5-year relative survival rate for breast cancer is 91%, but that drops to 86% at 10 years and 81% at 15 years.
• The 5-year relative survival rate is over 99% for breast cancer diagnosed at a localized stage but drops to 87% for regional-stage and 32% for distant-stage disease.
• American Indian/Alaska Native women have a 10% lower breast cancer incidence than White women but 6% higher mortality.

Similar to the ACS report, a recent study published in JAMA Network Open reported rising breast cancer incidence among US women aged 20-49 years of different races in different age groups over the past 2 decades.

The increased incidence of breast cancer in younger women “is an area of concern and an area where we really need to spend more effort trying to understand why,” said lead study author and breast surgeon Adetunji T. Toriola, MD, PhD, MPH, of Washington University in St Louis, Missouri.

Although reproductive and lifestyle factors, such as weight gain, diet, and physical activity, may contribute to the growing breast cancer incidence in younger women — and preliminary findings from Dr. Toriola’s own research suggest that reproductive factors may be a particularly strong driver — environmental factors, including exposure to forever chemicals, may also play a role.

Early-life factors, such as exposure to toxins, remain an underexplored area, Dr. Toriola noted, stressing the importance of teasing out the long-term effects of environmental exposures in puberty and during adolescence.

Overall, the trends observed both in this study and the ACS report highlight the need for enhanced prevention efforts that address racial disparities as well as the rising incidence in young women, said Dr. Toriola, also professor of surgery at the Washington University Institute of Public Health, St Louis.

For now, Dr. Toriola urges women to “engage with mammographic screening as soon as qualified” as per guidelines. Women at average risk should go for screening beginning at age 40, and those with a family history or other risk factors should talk to their physician about earlier screening, he said.

Ms. Giaquinto is employed by the ACS, which receives grants from private and corporate foundations, including foundations associated with companies in the health sector, for research outside of the submitted work. Dr. Toriola reported having no disclosures.

• In 2024, an estimated 310,720 new invasive breast cancers and 56,500 cases of ductal carcinoma in situ will be diagnosed among women in the United States, and an additional 2790 cases will be diagnosed in men.
• On the mortality front, in 2024, approximately 42,250 women are expected to die of breast cancer; 530 breast cancer deaths are anticipated in men.
• As for the lifetime risk for breast cancer, approximately one in eight women in the United States (13.1%) will be diagnosed with invasive breast cancer; 1 in 43 (2.3%) will die from the disease.
• The 5-year relative survival rate for breast cancer is 91%, but that drops to 86% at 10 years and 81% at 15 years.
• The 5-year relative survival rate is over 99% for breast cancer diagnosed at a localized stage but drops to 87% for regional-stage and 32% for distant-stage disease.
• American Indian/Alaska Native women have a 10% lower breast cancer incidence than White women but 6% higher mortality.

Similar to the ACS report, a recent study published in JAMA Network Open reported rising breast cancer incidence among US women aged 20-49 years of different races in different age groups over the past 2 decades.

The increased incidence of breast cancer in younger women “is an area of concern and an area where we really need to spend more effort trying to understand why,” said lead study author and breast surgeon Adetunji T. Toriola, MD, PhD, MPH, of Washington University in St Louis, Missouri.

Although reproductive and lifestyle factors, such as weight gain, diet, and physical activity, may contribute to the growing breast cancer incidence in younger women — and preliminary findings from Dr. Toriola’s own research suggest that reproductive factors may be a particularly strong driver — environmental factors, including exposure to forever chemicals, may also play a role.

Early-life factors, such as exposure to toxins, remain an underexplored area, Dr. Toriola noted, stressing the importance of teasing out the long-term effects of environmental exposures in puberty and during adolescence.

Overall, the trends observed both in this study and the ACS report highlight the need for enhanced prevention efforts that address racial disparities as well as the rising incidence in young women, said Dr. Toriola, also professor of surgery at the Washington University Institute of Public Health, St Louis.

For now, Dr. Toriola urges women to “engage with mammographic screening as soon as qualified” as per guidelines. Women at average risk should go for screening beginning at age 40, and those with a family history or other risk factors should talk to their physician about earlier screening, he said.

Ms. Giaquinto is employed by the ACS, which receives grants from private and corporate foundations, including foundations associated with companies in the health sector, for research outside of the submitted work. Dr. Toriola reported having no disclosures.

Common arm positions for blood pressure (BP) measurements that stray from guidelines — arm in lap or hanging at side — led to substantial overestimation of hypertension in a study published in JAMA Internal Medicine.

Guidelines for BP measurement recommend arm support on a desk with the midcuff at heart level. Overestimating BP can lead to unnecessary patient follow-up and overtreatment. Hypertension affects approximately 86 million  adults in the United States and more than 1 billion people globally.

This study has widespread implications given the number of settings where BP checks are performed and the growth in patients taking their own BP readings at home, said Donald DiPette, MD, who was not part of the research and was asked to comment on the findings. Dr. DiPette is the Distinguished Health Sciences Professor at the School of Medicine, University of South Carolina, Columbia.
 

Substantial Overestimation

In the crossover, randomized trial of 133 adults, Hairong Liu, MHS, with the Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, and colleagues found that supporting the arm on the lap overestimated systolic BP (SBP) by 3.9 mmHg and diastolic BP (DBP) by 4.0 mm Hg. When the arm hung at the side, readings overestimated SBP by 6.5 mm Hg and DBP by 4.4 mm Hg, with consistent results across subgroups.

Participants were randomly assigned to get a series of BP measurements with the arm positioned in three ways: Supported on a desk; hand supported on lap; and arm unsupported at the side. Because BP readings are intrinsically variable, all had a fourth set of BP measurements with the arm supported on a desk. 

Participants’ mean age was 57 years; 48 participants (36%) had SBP of ≥ 130 mm Hg; and 55 participants (41%) had a body mass index of ≥ 30.

Two researcher team staff members conducted all the measurements. They received standardized training and completed a certification test in BP measurement, administered by a study author. Measurements were taken from 9 am to 6 pm using a validated oscillometric BP device (ProBP 2000 Digital Blood Pressure Device, Welch Allyn). Only the right arms were used unless a specific condition was present, such as an open sore.
 

Study’s Design Sets It Apart

The authors wrote that the design of the study set this work apart. “Earlier studies have shown that unsupported or arm positioning below heart level can overestimate SBP by 4-23 mm Hg and DBP by 3-12 mm Hg.” But the strength of this study is the randomized, crossover design, “which is in contrast to the majority of published studies where the order of arm positions before seated BP measurement was not randomized or not clearly described.”

Dr. DiPette, who says, “I’ve given my career to understanding hypertension,” praised the design as well.

Randomization of which position patients were assigned to first was important because the first reading is often higher than subsequent readings, Dr. DiPette said.

“That makes sense as the person acclimatizes to the environment,” he explained. BP can even vary within the same reading, he noted.
 

Incorrect Readings for Many Reasons

Incorrect measures are common given the number of settings and number of providers and patients taking blood pressure even with training, certification in the method, and educational materials.

“We recommend taking a blood pressure in any possible setting you can. Because it’s that critical,” he said. “Most of the time it’s taken in busy primary care settings. The pressures are there. Most times it’s only one reading. It’s the medical environment of today.”

He noted that although this study finds overestimation, different arm positions not recommended by guidelines could potentially result in underestimation of hypertension. 

“I liken the BP measurement to a laboratory test that has clear treatment implications. We would want the BP measurement to have the same rigorous accuracy as a blood test or radiologic machine,” he said. 

Dr. DiPette said more education is needed for patients as well as providers as patients may be monitoring their own BP at home. Patients should also know they can ask for a measurement to be repeated, know the correct arm position recommended by guidelines, and the implications of incorrect readings, he said.

This study was supported by Resolve to Save Lives, which is funded by Bloomberg Philanthropies, the Bill and Melinda Gates Foundation, and Gates Philanthropy Partners, which is funded with support from the Chan Zuckerberg Foundation. 

Ms. Liu reported grants from Resolve to Save Lives outside the submitted work. One coauthor reported grants from the National Institutes of Health and personal fees from Kowa, RhythmX AI, and Fukuda Denshi outside the submitted work. Dr. DiPette declared no relevant financial relationships. He was part of a leadership team that developed World Health Organization guidelines on hypertension.

The latest research on therapeutic management of patients with relapsing-remitting multiple sclerosis (MS) presented at the European Committee for Treatment and Research in Multiple Sclerosis 2024 Congress is reported by Dr Patricia Coyle from Stony Brook University Hospital, in Stony Brook, New York. 

Dr Coyle first discusses a registry study looking at initiation of monoclonal antibody therapy for patients with pediatric-onset MS. Results showed a significant reduction in disability at age 23 and beyond when therapy was initiated in childhood.   

Next, Dr Coyle discusses a trial examining the safety and efficacy of frexalimab, a second-generation anti-CD40L antibody. In an open-label extension trial through 72 weeks, frexalimab provided a sustained reduction of disease activity, as measured by MRI, and was well tolerated. 

She then details a study looking at the effects of disease-modifying therapies (DMTs) on pregnancy outcomes in patients with MS. Using a German MS registry, researchers looked at 3722 pregnancies, 2885 with DMT exposure, and concluded that most pregnancy outcomes are unaffected by DMT exposure; however, the data showed the potential risk for reduced birth rates. 

Finally, Dr Coyle examines the efficacy of the Bruton tyrosine kinase (BTK) inhibitor tolebrutinib, as evidenced by the HERCULES trial and the two GEMINI trials. In HERCULES, the BTK inhibitor reduced 6-month disability progression by a significant 31% compared with placebo.

In 2024, the Royal Swedish Academy of Sciences is honoring two US researchers with the Nobel Prize in Medicine for the discovery of a fundamental principle of how gene activity is regulated. Victor Ambros, PhD, a researcher at the University of Massachusetts Chan Medical School, Worcester, and Gary Ruvkun, PhD, professor of genetics at Harvard Medical School in Boston, Massachusetts, discovered microRNAs, a new class of RNA molecules.

“Their groundbreaking discovery in the small worm Caenorhabditis elegans revealed a completely new principle of gene regulation. This turned out to be essential for multicellular organisms, including humans,” said the Nobel Assembly in a statement.
 

Protein Expression 

Genetic information flows from DNA during transcription to messenger RNA (mRNA) and then to protein biosynthesis. In that stage, mRNAs are translated so that proteins are produced according to the genetic instructions stored in the DNA.

Different cell types or tissues express unique sets of proteins, however. This specialized expression results from precise regulation of gene activity, so that in each cell type, only the correct set of genes is active. In this way, for example, muscle cells, intestinal cells, and various types of nerve cells can fulfill their functions.

Furthermore, gene activity must constantly be fine-tuned to adapt cell functions to changing conditions in our body and environment. When gene regulation goes awry, it can lead to serious outcomes such as cancer, diabetes, or autoimmune diseases. Therefore, understanding the regulation of gene activity has been an important goal for many decades.

In the 1960s, researchers had shown that specialized proteins called transcription factors bind to specific regions of DNA and control the flow of genetic information by determining which mRNAs are produced. Since that time, thousands of transcription factors have been identified. For a long time, scientists thought that the main principles of gene regulation were understood. 
 

Roundworm Research 

In the late 1980s, Dr. Ambros and Dr. Ruvkun were postdoctoral researchers in the laboratory of Robert Horvitz, PhD, who received the Nobel Prize in 2002 with Sydney Brenner and John Sulston. In Dr. Horvitz’s laboratory, they studied the relatively inconspicuous, 1-mm long roundworm C elegans.

Despite its small size, C elegans has many specialized cell types such as nerve and muscle cells that are also found in larger, more complex animals. These features make it a popular animal model.

Dr. Ambros and Dr. Ruvkun were interested in genes that ensure that different cell types develop at the right time. They examined two mutated worm strains, lin-4 and lin-14, that exhibited defects in the temporal activation of specific genes during development. The laureates wanted to identify mutated genes and understand their function.

Dr. Ambros had previously shown that lin-4 appeared to be a negative regulator of lin-14. But how lin-14 activity was blocked was unknown.
 

Collaboration Yields Breakthrough

After his postdoctoral years, Dr. Ambros analyzed the lin-4 mutant in his newly established laboratory at Harvard University. Systematic mapping allowed the cloning of the gene and led to an unexpected result: lin-4 produced an unusually short RNA molecule that lacked a code for protein synthesis. These surprising results suggested that this small RNA from lin-4 was responsible for inhibiting lin-14. 

At the same time, Dr. Ruvkun, in his newly founded laboratory at Massachusetts General Hospital and Harvard Medical School, studied the regulation of lin-14. In contradiction to the current understanding of gene regulation, he showed that it was not the production of lin-14 mRNA that was inhibited by lin-4. The regulation seems to occur at a later stage in the gene expression process, namely through the shutdown of protein synthesis. In addition, a section in lin-14 mRNA was discovered to be necessary for inhibition by lin-4.

The two laureates compared their results, leading to a groundbreaking discovery. The short lin-4 sequence matched complementary sequences in the relevant section of the lin-14 mRNA. Dr. Ambros and Dr. Ruvkun conducted further experiments showing that the lin-4 microRNA silences lin-14 by binding to the complementary sequences of its mRNA, thus blocking the production of the lin-14 protein. A new principle of gene regulation, mediated by a previously unknown type of RNA, the microRNA, had been discovered.
 

Subdued Initial Response

The results were published in Cell in 1993 and initially received little attention. However, interest grew in 2000 when Dr. Ruvkun’s research group published the discovery of another microRNA encoded by let-7.

In contrast to lin-4, let-7 was highly conserved and present throughout the animal kingdom. The article sparked great interest. In the following years, hundreds of microRNAs were identified. Today, researchers know that there are more than 1000 genes for various microRNAs in humans and that gene regulation by microRNAs is found in all multicellular organisms.

In addition to mapping new microRNAs, experiments by several research groups have elucidated fundamental mechanisms. Their binding leads to inhibition of protein synthesis or degradation of mRNA. Interestingly, a single microRNA can regulate the expression of many genes. Conversely, a single gene can be regulated by multiple microRNAs, thus coordinating and fine-tuning entire gene networks.

The cellular machinery for producing functional microRNAs is also used to produce other small RNA molecules in plants and animals, for example, as a means of protecting plants from viral infections. Andrew Z. Fire and Craig C. Mello, who were awarded the Nobel Prize in 2006, described RNA interference, in which specific mRNA molecules are inactivated by the addition of double-stranded RNA molecules to cells.
 

Small RNAs, Great Importance

Gene regulation by microRNA has likely existed for hundreds of millions of years. This mechanism has enabled the evolution of increasingly complex organisms.

From genetic research, it is known that cells and tissues do not develop normally without microRNAs. Abnormal regulation can lead to cancer. Mutations in genes encoding microRNAs cause, among other things, congenital deafness and eye and skeletal diseases. And mutations in one of the proteins required for microRNA production lead to the DICER1 syndrome, a rare but severe syndrome associated with cancer in various organs and tissues.

When gene regulation goes awry, it can lead to serious outcomes such as cancer, diabetes, or autoimmune diseases. Therefore, understanding the regulation of gene activity has been an important goal for many decades.

In the 1960s, researchers had shown that specialized proteins called transcription factors bind to specific regions of DNA and control the flow of genetic information by determining which mRNAs are produced. Since that time, thousands of transcription factors have been identified. For a long time, scientists thought that the main principles of gene regulation were understood. 
 

Roundworm Research 

In the late 1980s, Dr. Ambros and Dr. Ruvkun were postdoctoral researchers in the laboratory of Robert Horvitz, PhD, who received the Nobel Prize in 2002 with Sydney Brenner and John Sulston. In Dr. Horvitz’s laboratory, they studied the relatively inconspicuous, 1-mm long roundworm C elegans.

Despite its small size, C elegans has many specialized cell types such as nerve and muscle cells that are also found in larger, more complex animals. These features make it a popular animal model.

Dr. Ambros and Dr. Ruvkun were interested in genes that ensure that different cell types develop at the right time. They examined two mutated worm strains, lin-4 and lin-14, that exhibited defects in the temporal activation of specific genes during development. The laureates wanted to identify mutated genes and understand their function.

Dr. Ambros had previously shown that lin-4 appeared to be a negative regulator of lin-14. But how lin-14 activity was blocked was unknown.
 

Collaboration Yields Breakthrough

After his postdoctoral years, Dr. Ambros analyzed the lin-4 mutant in his newly established laboratory at Harvard University. Systematic mapping allowed the cloning of the gene and led to an unexpected result: lin-4 produced an unusually short RNA molecule that lacked a code for protein synthesis. These surprising results suggested that this small RNA from lin-4 was responsible for inhibiting lin-14. 

At the same time, Dr. Ruvkun, in his newly founded laboratory at Massachusetts General Hospital and Harvard Medical School, studied the regulation of lin-14. In contradiction to the current understanding of gene regulation, he showed that it was not the production of lin-14 mRNA that was inhibited by lin-4. The regulation seems to occur at a later stage in the gene expression process, namely through the shutdown of protein synthesis. In addition, a section in lin-14 mRNA was discovered to be necessary for inhibition by lin-4.

The two laureates compared their results, leading to a groundbreaking discovery. The short lin-4 sequence matched complementary sequences in the relevant section of the lin-14 mRNA. Dr. Ambros and Dr. Ruvkun conducted further experiments showing that the lin-4 microRNA silences lin-14 by binding to the complementary sequences of its mRNA, thus blocking the production of the lin-14 protein. A new principle of gene regulation, mediated by a previously unknown type of RNA, the microRNA, had been discovered.
 

Subdued Initial Response

The results were published in Cell in 1993 and initially received little attention. However, interest grew in 2000 when Dr. Ruvkun’s research group published the discovery of another microRNA encoded by let-7.

In contrast to lin-4, let-7 was highly conserved and present throughout the animal kingdom. The article sparked great interest. In the following years, hundreds of microRNAs were identified. Today, researchers know that there are more than 1000 genes for various microRNAs in humans and that gene regulation by microRNAs is found in all multicellular organisms.

In addition to mapping new microRNAs, experiments by several research groups have elucidated fundamental mechanisms. Their binding leads to inhibition of protein synthesis or degradation of mRNA. Interestingly, a single microRNA can regulate the expression of many genes. Conversely, a single gene can be regulated by multiple microRNAs, thus coordinating and fine-tuning entire gene networks.

The cellular machinery for producing functional microRNAs is also used to produce other small RNA molecules in plants and animals, for example, as a means of protecting plants from viral infections. Andrew Z. Fire and Craig C. Mello, who were awarded the Nobel Prize in 2006, described RNA interference, in which specific mRNA molecules are inactivated by the addition of double-stranded RNA molecules to cells.
 

Small RNAs, Great Importance

Gene regulation by microRNA has likely existed for hundreds of millions of years. This mechanism has enabled the evolution of increasingly complex organisms.

From genetic research, it is known that cells and tissues do not develop normally without microRNAs. Abnormal regulation can lead to cancer. Mutations in genes encoding microRNAs cause, among other things, congenital deafness and eye and skeletal diseases. And mutations in one of the proteins required for microRNA production lead to the DICER1 syndrome, a rare but severe syndrome associated with cancer in various organs and tissues.

In 2024, the Royal Swedish Academy of Sciences is honoring two US researchers with the Nobel Prize in Medicine for the discovery of a fundamental principle of how gene activity is regulated. Victor Ambros, PhD, a researcher at the University of Massachusetts Chan Medical School, Worcester, and Gary Ruvkun, PhD, professor of genetics at Harvard Medical School in Boston, Massachusetts, discovered microRNAs, a new class of RNA molecules.

“Their groundbreaking discovery in the small worm Caenorhabditis elegans revealed a completely new principle of gene regulation. This turned out to be essential for multicellular organisms, including humans,” said the Nobel Assembly in a statement.
 

Protein Expression 

Genetic information flows from DNA during transcription to messenger RNA (mRNA) and then to protein biosynthesis. In that stage, mRNAs are translated so that proteins are produced according to the genetic instructions stored in the DNA.

Different cell types or tissues express unique sets of proteins, however. This specialized expression results from precise regulation of gene activity, so that in each cell type, only the correct set of genes is active. In this way, for example, muscle cells, intestinal cells, and various types of nerve cells can fulfill their functions.

Furthermore, gene activity must constantly be fine-tuned to adapt cell functions to changing conditions in our body and environment. When gene regulation goes awry, it can lead to serious outcomes such as cancer, diabetes, or autoimmune diseases.

A 1-year course of methotrexate (MTX) in clinically suspected arthralgia may prevent the development of rheumatoid arthritis (RA) in at-risk individuals who test negative for anti-citrullinated protein antibody (ACPA), according to 4-year results from the TREAT EARLIER study.

While 2-year data did not show a preventive effect, researchers risk-stratified patients in this most recent data. The previous study also grouped all individuals together, while this new analysis separated patients by seropositivity.

“Heterogeneity in risk of rheumatoid arthritis development in ACPA–negative participants with clinically suspect arthralgia might have concealed a treatment effect due to dilution,” wrote senior author Annette H. van der Helm-van Mil, MD, PhD, professor of rheumatology at Leiden University Medical Center, Leiden, the Netherlands, and colleagues. “Therefore, risk-stratified analyses are required to adequately assess the possibility of prevention of rheumatoid arthritis in people with clinically suspect arthralgia who are ACPA–negative.”

Leiden University

To qualify for the study, participants needed to have recent-onset joint pain that a treating rheumatologist suspected of progressing to RA. Second, participants had to have subclinical joint inflammation, detected via MRI.

These are “promising results” for a group where predicting risk for RA has been more difficult than for their ACPA–positive counterparts, said Kevin Deane, MD, PhD, a professor of medicine and rheumatologist at the University of Colorado School of Medicine, Aurora, who was not involved with the study. However, additional research is necessary to investigate these findings.

The clinical utility of this finding is also unclear, he noted, as it would be an “extensive process” for all ACPA–negative individuals with joint pain to undergo MRI screening, he continued.

“It’s hard to find people who would meet these criteria, and healthcare systems need to understand how ultimately this could be implemented in clinical care,” he said.
 

Adding Risk Stratification

The TREAT EARLIER trial included 236 participants; nearly two thirds were women, and 77% were ACPA–negative (specifically for anti-cyclic citrullinated peptide 2). Patients randomly assigned to active treatment received a single intramuscular glucocorticoid injection (methylprednisolone 120 mg) upon inclusion and then completed a 1-year course of MTX. The comparator group received a single placebo injection at the beginning of the trial and a 1-year course of placebo tablets. All trial screenings and visits were conducted at the Leiden University Medical Center.

At the 2-year mark, there was no difference in the development of RA between the treatment and placebo groups, although there was improvement in joint pain, physical functioning, and MRI-detected joint inflammation in all at-risk groups given MTX — ACPA–positive patients and those at high risk for clinical arthritis development.

MTX delayed the onset of RA, with a statistically significant difference between treatment and placebo at 6 and 12 months, but not at 24 months.

For this 4-year analysis, published in The Lancet Rheumatology, authors stratified patients at their time of enrollment according to their risk of developing RA based on a published model for predicting inflammatory arthritis. Predictors included ACPA positivity (2 points), rheumatoid factor positivity (1 point), more than two locations of subclinical inflammation on MRI (2 points), and presence of metacarpophalangeal extensor tenosynovitis on MRI (1 point).

Patients with at least 4 points were classified as “high-risk,” with a 70% or higher predicted risk of developing RA. Participants with 2-3 points were at “increased risk” — translating to a 25%-70% higher likelihood of developing the condition. Low-risk patients, with 0-1 points, had < 25% chance of developing RA.

Of the 182 ACPA–negative participants in the study, none were considered high risk, 66 (36%) were at increased risk, and 116 (64%) were at low risk.
 

Decreased Rates of RA Development

Of these ACPA–negative patients stratified as increased risk, 3 of 35 (9%) in the treatment group developed RA, compared with 9 of 31 (29%) in the placebo arm (hazard ratio [HR], 0.27; P = .034).

All 54 ACPA–positive patients enrolled in the study were classified as either increased risk or high risk, but the treatment showed no difference in the rate of RA development in this group, and more than half (56%) developed RA during 4 years of follow-up. However, Dr. van der Helm-van Mil noted that the 2-year data showed treatment improved the severity of subclinical inflammation and symptoms over time in these patients.

The 5-year data from the trial, including physical function and other measures of disease burden, will be analyzed in 2025, she said, and will reveal whether ACPA–negative patients treated with MTX had sustained improvements in these measures.

Additional studies are needed to validate these findings, Dr. van der Helm-van Mil said, but the results indicate that ACPA–positive and ACPA–negative patients “are different populations, and we should evaluate them separately.”

Future RA prevention studies should also risk stratify patients before enrollment so that patients at low risk of developing the disease are not included in the interventions. “You can’t expect a treatment effect if there is no risk for disease,” she added.
 

Is It Cost-Effective?

In a separate analysis, published in Annals of the Rheumatic Diseases, Dr. van der Helm-van Mil and colleagues sought to investigate the cost-effectiveness of the TREAT EARLIER intervention at 2 years of follow-up.

“There is an ongoing debate whether people with arthralgia at risk for RA should be treated with DMARDs [disease-modifying antirheumatic drugs]; however, the economic effects of an intervention in the arthralgia at risk phase are unknown.”

The analysis calculated healthcare productivity and work productivity costs from enrollment to 2 years of follow-up. To demonstrate effect, they also calculated change in quality-adjusted life years (QALYs).

Over the course of 2 years, estimated costs for the treatment arm were €4809 lower (−$5304) than the placebo arm per patient. Lower productivity costs accounted for 97% of this difference.

The treatment arm also resulted in a small improvement (+0.041) in QALYs, compared with placebo.

“These data provide the first evidence that first-line treatment aiming at secondary prevention in arthralgia at-risk for RA is cost-effective,” the authors wrote.

Dr. van der Helm-van Mil emphasized that this cost analysis used only 2-year follow-up data (rather than the newly published 4-year data) and did not differentiate ACPA–negative patients. Despite including a greater heterogeneity of patients, the intervention was still cost-effective. A future analysis that includes 5-year follow-up data and stratifies patients by ACPA status and excludes low-risk individuals could demonstrate more cost benefits to a temporary MTX regimen, she said.

Considering the costs of these preventive interventions is important, added Dr. Deane, who agreed that future analyses should examine cost-effectiveness in groups at high risk of developing RA. (Dr. Deane noted that he had reviewed this article for publication.) However, this analysis did not include the costs of screening patients before enrollment in the study.
