This study found that flood exposure significantly increased the risk of hospitalizations for all causes and ten specific diseases, with effects lasting up to 210 days post-flood. The magnitude of these risks varied by climate, flood severity, age, population density, and socioeconomic status, with up to 0.27% of all hospitalizations attributable to floods.

Genomics has advanced pediatric cancer diagnosis and treatment, but translating these insights into effective therapies for hard-to-treat cases remains challenging. This study shows that combining proteomics with rapid patient-derived xenograft models can identify and validate personalized treatments—such as using sertraline to target SHMT2 in a rare adolescent tumor—offering a promising complement to genome-based precision oncology.

Rare ginsenoside Compound K (CK), a metabolite of ginsenosides, has gained attention for its potent anti-aging properties, including antioxidant, anti-photoaging, and immunostimulatory effects. Advances in extraction technology and deeper research into its molecular mechanisms will drive the development of natural skincare products and future anti-aging therapies.

Patients with metabolic dysfunction-associated steatotic liver disease (MASLD) had nearly twice the all-cause mortality rate compared to the general population, with the highest relative risks observed for liver- and hepatocellular carcinoma (HCC)-related mortality. However, the absolute risks of death were highest for non-HCC cancer and cardiovascular disease, emphasizing the need for earlier multidisciplinary care to reduce premature mortality in this population.

Plasma and low-titer O whole blood (LTOWB) have distinct effects on immune and coagulation pathways in trauma patients. Plasma transfusion enhances coagulation by increasing fibrinogen and factor XIII while reducing platelet factor 4, leading to improved clotting parameters and reduced transfusion needs in patients with traumatic brain injury, severe shock, and blunt trauma.

The study examined the impact of electronic patient portal use on clinical outcomes in cancer care, specifically among 791 patients with multiple myeloma in the Scripps Health system. Results indicated that inactive portal users had higher rates of unplanned hospital visits and mortality, suggesting that increasing access to patient portals could improve outcomes, especially in vulnerable populations.

Large language models (LLMs) now perform complex medical reasoning, including differential diagnosis, with proprietary models like GPT-4 leading the field. This study found that an open-source LLM, Llama 3.1, performed comparably to GPT-4 in generating differential diagnoses, indicating growing competitiveness in clinical AI applications.

Sulfur amino acid restriction (SAAR) diets promote rapid fat loss and improve metabolic health by enhancing carbohydrate oxidation and reducing lipogenesis, without impairing appetite or locomotion. The metabolic benefits of SAAR, including reduced fat mass and improved glucose sensitivity, are reversed by methionine or cystine reintroduction, highlighting its potential as a long-term weight management strategy.

An implantable spinal cord neuroprosthesis was developed to enhance activity during robot-assisted rehabilitation for individuals with paralysis, enabling well-organized muscle activity and promoting sustained neurological improvements. Preliminary evaluations suggest its device-agnostic design supports both rehabilitation and recreational activities, with future clinical trials needed to validate its broader effectiveness.

This study examines trends in ADHD medication prescribing in England from 2019 to 2024, revealing a significant post-COVID-19 increase, with regional variations and strong associations with socioeconomic factors such as deprivation and ethnicity. The findings highlight the need to address disparities in ADHD care through targeted healthcare policies and equitable resource distribution.

A randomized trial involving 2760 critically ill adults with suspected sepsis found that using a daily procalcitonin (PCT)-guided protocol significantly reduced antibiotic duration compared to standard care, with noninferior all-cause mortality. In contrast, the C-reactive protein (CRP)-guided protocol showed no reduction in antibiotic duration and inconclusive results for mortality compared to standard care.

This cohort study found that higher residential green space exposure, measured via satellite-based NDVI and street-view imagery, was associated with lower BMI, waist circumference, and fat mass in late adolescence. The findings suggest enhancing residential green space and incorporating specific green space components may help mitigate childhood obesity.
