Tailoring prostate cancer radiotherapy to body clock could cut long-term side effects

A study by Leicester researchers shows that the timing of radiotherapy treatment may be as important as how it is given for prostate cancer patients.

Multivitamins boost key vitamin levels, but do they improve your health?

A scoping review of 157 clinical trial reports found that multivitamins consistently improved circulating levels of folate, vitamin B6, and vitamin B12, while other nutritional and clinical effects varied by formulation, population, and baseline nutritional status. Selected prenatal and cognitive outcomes improved in some trials, but evidence for cardiovascular disease prevention was largely negative, and the review could not establish the overall certainty of clinical benefits.

Worried nuts will cause weight gain? A large review puts that concern in perspective

A systematic review and meta-analysis of randomized trials found that eating nuts modestly reduced body fat and improved cholesterol levels without significantly changing body weight. The review did not establish that nuts rich in monounsaturated fats offered greater body-composition benefits than those rich in polyunsaturated fats.

Can broccoli sprouts help with insulin resistance? New review offers clues

A review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their clinical benefits.

New study reveals why college athletes experience severe burnout

As both athletes and students, college athletes face a lot of pressure. In fact, the NCAA Student-Athlete Health and Wellness Study (2023) found that 16-35% of athletes felt mentally exhausted most days.

Circadian desynchronization: The hidden cost of daylight saving time transitions

Turning the clocks back an hour each fall can feel like a gift: an extra hour of sleep. But the tradeoff is less daylight in the evening, and the annual switch continues to earn mixed reviews.

Cedars-Sinai initiative helps LGBTQ+ communities overcome barriers to quitting tobacco

Quitting tobacco can be difficult, especially when people face barriers to healthcare or lack support that reflects their experiences.

Researchers tested an unexpected addition to vaginal treatment: oxygen

Researchers investigated the effects of topical vaginal oxygen treatment, alone or combined with antimicrobials, on the vaginal microbiota of 22 women with bacterial vaginosis or vaginitis. The combined treatment reduced the relative abundance of strict anaerobes and increased Lactobacillus abundance, but the absence of an antimicrobial-only control group prevented researchers from establishing whether oxygen contributed independently to these changes.

Ketones may change sleep patterns, but not always for the better

Researchers reviewed animal and human studies and found that ketone bodies may affect sleep stages through energy metabolism and cellular signaling, with the clearest direct evidence involving acetoacetate in mice. They reported mixed human findings and called for controlled studies to separate ketone-specific effects from changes linked to diet, disease, circadian timing, and physiological stress.

Prefrontal cortex activity fails to predict individual emotion regulation

A supervisor criticizes a report in front of the entire team – you feel exposed and hurt. But if you tell yourself, "She takes my work seriously and wants the project to succeed," the same situation can lose some of its intensity. In psychology, this deliberate reinterpretation is called cognitive reappraisal.

Review highlights essential neurological considerations for gender dysphoria care

Gender dysphoria involves distress caused by a mismatch between a person's gender identity and sex assigned at birth.

One in four young Australians experienced physical abuse during childhood

New research shows one in four young people have experienced physical abuse in childhood at the hands of their parents - and most commonly before the age of ten.

A loneliness trial puts personalized nature-based support on the research agenda

In a randomized trial involving 320 adults experiencing loneliness, researchers found that loneliness scores declined in both a facilitated nature-based group program and an active signposting group, with no significant difference between them at three months. Neither approach significantly improved health-related quality of life, while exploratory analyses suggested that people with lower emotional wellbeing might benefit more from facilitated group activities.

Low vitamin B12 is linked to heart disease. Supplements tell a different story

A narrative review published in Nutrition Journal examines how vitamin B12 deficiency may contribute to cardiovascular disease through elevated homocysteine, endothelial dysfunction, oxidative stress and altered methylation. The authors found that B12 supplementation has not consistently prevented heart attacks or cardiovascular deaths in clinical trials, although combined B-vitamin therapy may modestly reduce stroke risk, particularly in populations without folic acid fortification.

Amyloid fibers help sperm deliver RNA to mouse embryos

Researchers identified RNA-associated amyloid fibrils in human seminal fluid and demonstrated that synthetic PAP fibrils could enter mammalian sperm. In mouse IVF experiments, these fibrils helped sperm deliver RNA to embryos, where the detected reporter-protein signal was at least tenfold higher than without fibril exposure.

Non-drug and non-surgical low back pain treatments are highly cost-effective options

Non-drug and non-surgical treatments for low back pain, including psychological support, exercise and self-management strategies are cost-effective interventions, according to a study published October 27th in the open access journal PLOS Medicine by Manuela Loureiro Ferreira from the George Institute for Global Health, Australia, and colleagues.

Plasma proteins offer clues to biological aging and mortality risk

A new study published in Geromedicine has identified 17 plasma proteins associated with all-cause mortality in older adults and found that several of these proteins also track with measures of biological aging across multiple organ systems.

Mount Sinai wins $4 million NIH grant to improve prediction of postoperative acute kidney injury

Researchers at the Icahn School of Medicine at Mount Sinai have received a five-year National Institutes of Health grant of approximately $4 million to improve prediction and prevention of postoperative acute kidney injury (AKI), a potentially serious complication after surgery.

First human endothelial cell atlas maps how blood vessels age

To uncover how endothelial cells, the inner linings of blood vessels. change over the course of a lifespan, an international research team led by Laura de Rooij at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences has created the Human Aging Endothelial Cell Atlas, the first comprehensive atlas of vascular aging.

Blocking cellular communication reduces the spread of deadly glioblastoma

In a new study published in Cancer Cell, researchers at VIB-KU Leuven reduced the spread of glioblastoma by interrupting specific interactions between the brain's immune cells and tumor cells.
