A new study from Mass General Brigham researchers found that early menopause may be a risk factor for Alzheimer's disease dementia. However, women who received hormone therapy around the time of menopause onset did not experience an increased risk of dementia. The study suggests that timing is crucial when it comes to hormone therapy, ...

Women surgeons remain underrepresented among NIH-funded surgeon-scientists over a 25-year period, despite early career success in receiving funding. This disparity underscores the necessity of targeted support to create a more diverse surgical research workforce.
Developing postoperative delirium is associated with a 40% faster rate of cognitive decline compared to those who do not develop delirium. The study, which followed 560 older adults for up to six years, found that delirium influences every time point and is linked to sharper drops in cognition and faster declines over time.
A new study found that California's Insurance Gender Nondiscrimination Act led to a significant increase in gender-affirming surgery utilization. The data suggests that similar policies could inform state legislative efforts to protect transgender and gender-diverse patients' health coverage.
The ProtecT trial found that active monitoring of prostate cancer has the same high survival rates after 15 years as radiotherapy or surgery. Men on active monitoring were more likely to see their cancer progress, but this didn't reduce their likelihood of survival.
A UK study reviewing over 90,000 vasectomies found that chronic scrotal pain occurs in just 0.2% of patients, while post-operative infection rates are around 1.6%. The study updates outdated figures and aims to encourage more men to undergo the procedure.

Key findings suggest a significant opportunity to improve compliance and patient outcomes, but inadequate resources and limited...
A new algorithm predicts female patients are at higher risk for kidney damage after aneurysm repair, with those having reduced glomerular filtration rate facing a 4.7 times increased risk. The algorithm could help identify patients at risk and optimize them before surgery.
A new review found that spinal cord stimulation is no better than a placebo for treating low back pain, with probably little to no benefit for people with the condition. The review also highlighted gaps in clinical data and called for future trials to be longer and more comprehensive.
A new study by Weill Cornell Medicine found that the FDA's mandate to limit opioid-acetaminophen combinations resulted in significant reductions in liver injuries. The mandate, implemented in 2014, limited the dosage of acetaminophen in these drugs, leading to a decline in hospitalizations and acute liver failure cases.
Women have a roughly 30-40% higher risk of dying following coronary artery bypass surgery, with female patients having a 2.8% rate of death during or soon after surgery compared to 1.7% for male patients.
Researchers found that patients receiving salvage radiation therapy (sRT) with PSA levels above 0.25 ng/mL had a 50% higher risk of death compared to those with lower PSA levels. The study suggests delaying sRT until PSA levels exceed 0.30 ng/mL may increase mortality risk.

The study found improved event-free survival rates in the neoadjuvant group, suggesting that starting immunotherapy before surgery generates better outcomes.
A case series study of 373,000 patients found that time from diagnosis to surgery over eight weeks was associated with worse overall survival. This delay may be linked to disadvantageous social determinants of health, suggesting the importance of timely surgical interventions in breast cancer care.
Researchers at Indiana University School of Medicine have identified a new type of cell called the vasculogenic fibroblast, which can help create new blood vessels for treatment. This discovery could lead to improved treatments for ischemic diseases such as diabetic wounds.
A phase 2 clinical trial shows that treating resectable stage 3 and 4 melanoma patients with pembrolizumab both before and after surgery greatly improves outcomes compared to pembrolizumab given only after surgery. This approach resulted in significantly longer event-free survival rates.
The average age of patients requiring anaesthesia increased by 2.3 years over the last decade, with a higher proportion of patients living with overweight and obesity. Surgical cases are becoming more complex, with a decrease in ASA 1 and an increase in ASA 2 and 3 patients.
A study by researchers at TUM found that gut bacteria play a crucial role in liver regeneration. The microbiome produces short-chain fatty acids, which are essential for liver cell growth and division. In mice treated with antibiotics, liver regeneration was delayed or not possible, but a
Researchers at the University of Montreal Hospital Research Centre identified two bacterial strains that can either increase or decrease the risk of intestinal leakage after surgery. Modifying patients' gut microbiota before surgery may reduce postoperative complications and improve recovery.
A tiny soft robot has been developed to help doctors perform surgery and search in hard-to-reach places. The robot uses ultraviolet light and magnetic force to climb on any surface, including walls and ceilings, without an external power supply.
Researchers re-examine molecular characteristics of WNT-subgroup patients to identify optimal treatment strategies for low-risk medulloblastoma. Key findings suggest that therapy-related late toxicity remains a concern, despite comparable survival rates between children and adolescents with this disease subtype.
Researchers found that IVC filters were effective in preventing pulmonary embolisms (PE) in patients with deep vein blood clots, even when used prophylactically. Approximately half of the patients had their filters removed without complication or recurrence of DVT or PE.
A new study found that preoperative surgeon intuition is an independent predictor of 30-day postoperative complications, but its predictive power is not as strong as a standardized risk calculator. The study suggests that the information gathered by the calculator is better at predicting outcomes than surgeons' gut feelings.
A new study links genetic changes in kidney cancer to patient outcomes, identifying four groups of patients based on mutation presence. This research may lead to more effective prediction of recurrence risk and personalized treatment for thousands of patients annually.
