The absolute risk was small, but those with high levels of regular physical activity were less susceptible to the triggering effect of episodic physical activity.
A study found that long-term bisphosphonate therapy is associated with an increased risk of subtrochanteric or femoral shaft fractures, while reducing typical osteoporotic fractures. The researchers suggest reconsidering extended therapy for patients at low fracture risk and exploring drug holidays to mitigate this risk.
Researchers analyzed data from 592 patients with type 1 diabetes and macroalbuminuria to identify predictors of End-Stage Renal Disease (ESRD) and pre-ESRD mortality. The study found that poor glycemic control increases ESRD risk but not pre-ESRD mortality, while improved lipid management affects both outcomes.
A recent study found that adhering to current guidelines for treating intensive-care unit patients with multi-drug resistant pneumonia may result in higher mortality rates. The authors suggest re-assessing the guidelines due to a lack of evidence supporting triple antibiotic therapy.
