Can folic acid prevent or promote breast cancer? It depends on dose and DNA
Folic acid plays a dual role in breast cancer depending on dose and context. While moderate intake may reduce risk, high levels or genetic variants disrupting metabolism may promote tumor progression via altered DNA methylation.
Study: Nicotine pouch use nearly doubles among U.S. high school students
The use of nicotine pouches - small, easily concealed sachets of nicotine and additives that are placed between the gum and lip - nearly doubled among U.S. high school students between 2023 and 2024, according to a new USC study.
Mindfulness-based therapy found to decrease opioid cravings and improve emotional health
Researchers from the University of California San Diego have found that Mindfulness-Oriented Recovery Enhancement (MORE) can help rewire the brain's response to natural healthy pleasure, leading to improved mood, greater attention to positive experiences and reduced opioid cravings.
Racial disparities in breast reconstruction persist despite ACA implementation
Despite steady increases in rates of immediate breast reconstruction (IBR) after mastectomy, racial disparities in IBR have persisted in the years since implementation of the Affordable Care Act (ACA), reports a study in the May issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons.
Parental or caregiver alcohol use tied to increased child maltreatment
A new systematic review has found that parents and other child caregivers who have alcohol-related diagnoses are twice as likely to maltreat children in their care than parents and caregivers with no alcohol-related diagnoses.
Rare TYROBP gene variant found in Finns linked to increased Alzheimer's risk
Found in the Finnish population, a rare variant of the TYROBP gene significantly increases the risk of Alzheimer's disease, a new study led by the University of Eastern Finland shows.
Curcumin shows promise for treating obesity, inflammation, and neurodegenerative diseases
Researchers explore the medicinal role of curcumin in the treatment and prevention of neuroinflammation and metabolic disorders.
New antiviral compounds show broad protection against COVID-19 variants
Novel Mpro inhibitors exhibit broad activity against SARS-CoV-2 and other coronaviruses.
ADHD and anxiety show different patterns in boys and girls
ADHD can exacerbate anxiety, and anxiety can exacerbate ADHD. Girls are particularly vulnerable to developing anxiety disorders, but researchers have recently discovered something that may help slow down – or prevent – the development of these types of disorders.
Study uncovers why anxiety and depression lead to low self-belief
Researchers at UCL have uncovered why individuals who experience anxiety and depression often struggle with persistent low self-belief in their abilities.
Exercise helps mitigate cancer treatment side effects
Exercise can counter the detrimental effects of cancer treatment, such as heart and nerve damage and brain fog, suggests an overarching review of the existing pooled data analyses of the most recent research, published online in the British Journal of Sports Medicine.
Higher cigarette taxes could save thousands of children's lives
A higher tax on cigarettes in low and middle-income countries can help to reduce child mortality, especially amongst the poorest children, a new study led by researchers at Karolinska Institutet and published in The Lancet Public Health suggests.
More permanent nurses could save lives and lower healthcare costs
Employing too few permanent nurses on hospital wards is linked to longer inpatient stays, readmissions, patient deaths, and ultimately costs more in lives and money, finds a long term study published online in the journal BMJ Quality & Safety.
Mathematical models point to broader antibiotic use as a tool against cholera
Cholera kills thousands of people and infects hundreds of thousands every year-and cases have spiked in recent years, leaving governments with an urgent need to find the best ways to control outbreaks.
Substance use drives up severity and hospital costs of scooter-related injuries
Analyzing data from the 2016-2021 National Inpatient Sample, UCLA researchers found that 25% of 7350 patients hospitalized for scooter-related injuries were using substances such as alcohol, opioids, marijuana and cocaine when injured.
Breast cancer deaths decline in young women across all racial and subtype groups
From 2010 to 2020, breast cancer deaths among women ages 20-49 declined significantly across all breast cancer subtypes and racial/ethnic groups, with marked declines starting after 2016, according to an analysis of data from the Surveillance, Epidemiology, and End Results (SEER) registry presented at the American Association for Cancer Research (AACR) Annual Meeting 2025, held April 25-30.
Study links pregnancy specific genes to poorer lung cancer outcomes in women
Lung cancer can co-opt genes that normally help a fetus develop and evade the mother's immune system. And while these pregnancy-specific glycoproteins (PSGs) can get activated in the cancers of both men and women, female patients had poorer outcomes, a Memorial Sloan Kettering Cancer Center (MSK) research team has found.
Financial Toxicity Tumor Board approach provides relief from cancer treatment costs
Financial toxicity, the financial distress linked to cancer treatment, significantly impacts patient outcomes. To combat this, the Atrium Health Levine Cancer Institute established a Financial Toxicity Tumor Board in 2019.
Brain damage linked to increased impulsivity and social influence
People who have damage to a specific part of their brains are more likely to be impulsive, and new research has found that damage also makes them more likely to be influenced by other people.
Study highlights changes in bladder and urinary tract health across the menopause transition
The menopause transition is often accompanied by a wide array of symptoms, some of which receive more attention than others.
