Informal human milk sharing among US mothers

JAMA Network Open

2025-11-06

(Press-News.org) About The Study: In this large, diverse sample of first-time mothers in the U.S., 1 in 27 participants reported feeding their infants shared human milk. Prior work indicates that families engage in many, but not all, recommended milk sharing risk mitigation measures and fear disclosing their milk sharing to practitioners. Given the prevalence in this study, pediatric practitioners should be aware that milk sharing occurs across demographics; they can counsel families considering or using shared milk on risks and risk-reduction strategies recommended by the Academy of Breastfeeding Medicine and the American Academy of Nursing, while noting that evidence on home pasteurization is still evolving.

Non-prescription pain meds work equally well for men and women after tooth extraction

2025-11-06

Over-the-counter pain medications work as well or better than opioids after wisdom tooth extraction for both men and women, according to a Rutgers Health-led follow-up to a landmark paper on comparative pain relief. That first paper on the collective experience of more than 1,800 trial patients found that the combination of ibuprofen and acetaminophen provided better pain relief than hydrocodone with acetaminophen for the first two days after surgery and greater satisfaction over the post-operative period. The new subgroup analysis, published in JAMA Network Open, demonstrated that the results held for both ...

Mifepristone access through community pharmacies when regulated as a routine prescription medication

2025-11-06

About The Study: The results of this study of pharmacies in British Columbia, Canada, suggest that when medication abortion is available as a routine health service and mifepristone is regulated as a routine prescription, pharmacists play a key role in providing geographically distributed access to medication abortion. These findings may inform policy and initiatives to enhance pharmacist referral networks and improve mifepristone access, as well as service planning for international jurisdictions considering a similar medication abortion ...

UBC study shows good B.C. abortion pill access, but gaps remain

2025-11-06

Most pharmacies in British Columbia can provide the abortion pill mifepristone within days, but uneven access still leaves some women facing barriers to this time-sensitive medication, according to new research. The study, published Nov. 6 in JAMA Network Open, offers the first province-wide look at pharmacy-level access to mifepristone in B.C. Mifepristone is used for medical abortions and can be prescribed across Canada by any physician or nurse practitioner and filled at community pharmacies. Initially available only from pharmacists who had completed a training module and pharmacies registered with the manufacturer, Health Canada removed these requirements ...

Researchers find that adaptive music technologies enhance exercise engagement and enjoyment

2025-11-06

Researchers from University of Jyväskylä have found that personalized interactive music systems – smart technologies that adapt rhythm and tempo to users’ movements – can make exercise more enjoyable and help people stay active longer. These systems, known as PIMSs, use real-time data from wearables and smartphones to adjust musical features such as beat, tempo, and style to match the user’s pace – whether walking, cycling or lifting weights. For example, when the systems detects you speeding up, it raises the music’s tempo to match your ...

Meditation retreat rapidly reprograms body and mind

2025-11-06

Researchers at the University of California San Diego have found that an intensive retreat combining multiple mind-body techniques, including meditation and healing practices, produced rapid and wide-ranging changes in brain function and blood biology. The researchers found that the retreat engaged natural physiological pathways promoting neuroplasticity, metabolism, immunity and pain relief. The findings, published in Communications Biology, provide insights into how consciousness and psychological practices can enhance physical health. Meditation and other mind-body practices ...

Biohub launches first large-scale scientific initiative combining Frontier AI with Frontier Biology to cure or prevent disease

2025-11-06

Mark Zuckerberg and Priscilla Chan today announced the launch of a first-of-its-kind initiative combining frontier artificial intelligence and frontier biology to dramatically accelerate scientific progress toward understanding and addressing human disease. Since its founding in 2016, Biohub’s multidisciplinary teams of scientists and engineers have developed groundbreaking technologies to observe, measure, and program biology at the cellular level. The organization has built the largest single-cell datasets and established large-scale compute ...

High-impact clinical trials generate promising results for improving kidney health - part 1

2025-11-06

The nonsteroidal mineralocorticoid receptor antagonist finerenone has been shown to reduce the risks of major clinical kidney and cardiovascular outcomes in individuals with chronic kidney disease (CKD) and type 2 diabetes. In the phase 3 FINE-ONE trial, investigators assessed the efficacy and safety of finerenone in people with CKD and type 1 diabetes, a patient population that has not had new therapies in the last 30 years. FINE-ONE randomized 242 patients to finerenone or placebo. “The study used albuminuria change over 6 months of treatment as endpoint and bridging biomarker to translate evidence of long-term kidney protective effects from type 2 diabetes and CKD ...

New hope for treating kidney disease in type 1 diabetes

2025-11-06

The drug finerenone has a positive effect on patients with type 1 diabetes and chronic kidney disease. The drug reduces the amount of proteins excreted in the urine of these patients. This reduction indicates that the degree of kidney damage is reduced and that the drug has a protective effect on kidney function. Clinical pharmacologist Hiddo Lambers Heerspink of the UMCG led a large international study into the effect of this drug. He will present the initial results of this study at the American Society of Nephrology conference in Houston, where he will present the results during the plenary ...

Populist parties choose divisive issues on purpose, researchers say

2025-11-06

Election researchers from across Europe have looked at how populist parties profile themselves on Facebook. Their findings are quite clear. "Populist parties much more often use controversial, divisive issues when they want to show themselves to potential voters," says Melanie Magin, a professor of media sociology at the Norwegian University of Science and Technology (NTNU's) Department of Sociology and Political Science. Magin and her fellow researchers believe this is probably quite deliberate in order to get the debate into a track that these parties believe they benefit from. The elections to the European Parliament ...

Hollings researcher co-leads AACR subcommittee calling for nicotine limits

2025-11-06

The American Association for Cancer Research (AACR) has endorsed a federal policy that would make cigarettes far less addictive. The proposed policy by the Food and Drug Administration (FDA) sets a maximum nicotine product standard, limiting nicotine levels in combustible cigarettes and related tobacco products to 0.7 milligrams per gram (mg/g) – about 95% less than what is currently allowed. That reduction would make cigarettes minimally or nonaddictive, striking at the chemical that keeps people hooked. The AACR policy statement is published in Clinical Cancer Research. Leading the policy statement ...
