Background: Hip fracture is common and associated with high morbidity and mortality rates. Selective serotonin reuptake inhibitors (SSRIs) influence platelet hemostasis and might result in abnormal bleeding. This study aims to determine whether the use of SSRIs in older patients undergoing hip fracture surgery is associated with the risk of perioperative red blood cell (RBC) transfusion.

Tropical ectotherms are already living in environments matching their thermal tolerance range and may be expected to conform to environmental temperatures. We tracked the body temperatures () of 163 estuarine crocodiles across 13 years and compared of 39 crocodiles to water temperature gathered using fish-borne sensors () across 3 years (2015-2018).

- A study was conducted during the COVID-19 pandemic in France to evaluate the effectiveness of various biomarkers in predicting short-term worsening (STW) of the disease in hospitalized patients.
- The research involved analyzing data from 511 consecutive COVID-19 patients across 20 hospitals, identifying key blood test markers that could help in severity triage.
- The results showed that out of the patients analyzed, 11.7% experienced STW, with certain biomarker levels at admission indicating a higher risk of rapid deterioration within seven days.
Article Synopsis
- - The study explores how social environments impact individual behavior, particularly under competition, suggesting that higher population density leads to greater behavioral variation and predictability among animals.
- - Using the eastern water dragon lizard, researchers found that while females were generally more sociable, there were no significant sex differences in behavioral variation or predictability.
- - The results indicate that for females, predictable social behavior is linked to improved survival, while males show a connection between average social behavior and fitness, pointing to sex-dependent effects of social predictability.
Article Synopsis
- Squamate reptiles, including the Australian water dragon, are diverse tetrapods that offer insights into amniote evolution.
- The Australian water dragon has a genome assembly of 1.8 Gb with 23,675 annotated protein-coding genes, highlighting its urban adaptability and social systems.
- Comparative analyses indicate gene expansions related to immune function, energy balance, and wound healing, making this genome a key resource for studying lizard evolution and resilience.
