Maternal obesity alters fetal liver metabolism via placental molecular signals

https://www.news-medical.net/news/20260826/Maternal-obesity-alters-fetal-liver-metabolism-via-placental-molecular-signals.aspx A mother's obesity during pregnancy may send molecular signals across the placenta that permanently alter her son's liver metabolism, according to a new study in mice published in Nature Communications. The research traces this effect to a maternal sEV–miRNA–epigenetic axis that links fetal liver programming to long-term metabolic health.

Gut bacteria may send different biological signals in Parkinson’s disease

https://www.news-medical.net/news/20260826/Gut-bacteria-may-send-different-biological-signals-in-Parkinsone28099s-disease.aspx A new study from the University of Oulu suggests that gut bacteria may send different biological signals in Parkinson’s disease. The findings add to growing evidence that changes in the gut could be linked to Parkinson’s disease and may eventually help researchers identify new underlying mechanisms for the condition.

Study tracks global patterns and socioeconomic inequalities in the burden of breast cancer

https://www.news-medical.net/news/20260826/Study-tracks-global-patterns-and-socioeconomic-inequalities-in-the-burden-of-breast-cancer.aspx Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death among women globally, accounting for nearly 2.3 million new cases and 670,000 deaths in 2022 alone. While traditional metrics like annual incidence rates provide a snapshot of disease burden, they do not capture the cumulative probability that an individual will face breast cancer over their entire lifetime. Moreover, the interplay of reproductive patterns, lifestyle factors, screening access, and treatment quality varies enormously across regions with different levels of economic development. Based on these challenges, there is a clear need for a more intuitive, comparable indicator that accounts for life expectancy and competing mortality risks to guide global cancer control strategies

Why living to 100 may depend on far more than diet and exercise

https://www.news-medical.net/news/20260825/Why-living-to-100-may-depend-on-far-more-than-diet-and-exercise.aspx From diet and exercise to social ties and genetics, researchers examined why the habits linked to healthier aging may not fully explain who survives to 100. In a recent critical narrative review published in the journal Minerva Medica, researchers synthesized multidisciplinary evidence investigating whether human longevity can be engineered through behavioral modifications and standardized lifestyle “recipes”. The review aimed to assess the scientific validity of the increasingly pervasive commercial and media narrative associating human longevity with lifestyle choices.

Ear Microbiome Composition and Its Role in Health and Disease

https://www.news-medical.net/health/Ear-Microbiome-Composition-and-Its-Role-in-Health-and-Disease.aspx From protective cerumen and resident microbes to striking shifts in bacterial and fungal communities, emerging sequencing research is uncovering a complex microbial ecosystem within the ear that may reshape our understanding of ear health and disease.

Lasers and Math Can Help Doctors Deliver Just the Right Amount of Medicine August 26, 2026 By: Henry Nonnemaker

https://www.nist.gov/blogs/taking-measure/lasers-and-math-can-help-doctors-deliver-just-right-amount-medicine When doctors need to deliver precise doses of medicine on a strict schedule, they often administer it intravenously. Intravenous drug delivery methods need to carefully control the flow of medicine into a patient. Knowing the medicine’s flow rate — or the volume of fluid flowing into the patient each second or minute — is crucial to delivering the right amount of medicine at the right time. Surprisingly, the correct amount is sometimes not very much at all. Imagine a one-liter bottle divided up into a billion parts. One of those parts is a nanoliter. Doctors may only need a handful of nanoliters of fluid to flow each minute.

Resilience and well-being as positive determinants of mental health in Israel amid challenges Rabab Awad* [1]ORCID iD , Alon Zamir [2,3]ORCID iD , Liat Ayalon [1] + +...

https://www.academia.edu/2997-9196/3/2/10.20935/MHealthWellB8346 The State of Israel, with its unique social fabric, provides a distinctive context for examining resilience and well-being as positive indicators of mental health. Although a growing body of research has addressed these issues, existing knowledge remains fragmented and lacks an integrative, multilevel synthesis. This narrative review synthesizes empirical research conducted in Israel since 2000 on resilience and well-being in the contexts of war and armed conflict, immigration waves, and the COVID-19 pandemic. The review is guided by a multidimensional analytical framework comprising two axes. The first examines resilience and well-being at the macro, meso, and micro levels, emphasizing societal-, institutional-, community-, and individual-level factors that potentially enhance or maintain resilience and well-being in the face of these challenges. The second compares findings across population groups, including ethnic groups, age cohorts, essential workers, and other vulnerable populations in Israeli society. The findings indicate that resilience and well-being vary across the individual, community, and societal levels and across different societal challenges, reflecting the interaction of personal, relational, and structural factors under prolonged stress. Overall, resilience and well-being emerge as key positive dimensions of mental health, highlighting the need for context-sensitive and multilevel approaches to strengthen adaptive functioning during challenging times. https://www.academia.edu/journals/academia-mental-health-and-well-being/articles?source=journal-top-nav
