Antithrombotic prophylaxis use and incidence of venous thromboembolism in lung cancer surgery: An observational retrospective study.

Introduction: Extended thromboprophylaxis with low-molecular-weight heparin (LMWH) for 28 days is recommended in patients undergoing major abdominal or pelvic cancer surgery, but the evidence for thoracic cancer surgery is weak. We aimed to evaluate the use of pharmacological thromboprophylaxis and incidence of venous thromboembolism (VTE) in adult patients undergoing lung cancer surgery in daily clinical practice.

Methods: Retrospective evaluation of a cohort of consecutive adult patients who had undergone lung cancer surgery.

Prehabilitation for Chilean frail elderly people - pre-surgical conditioning protocol - to reduce the length of stay: randomized control trial.

Background: Frail elderly patients have a higher risk of postoperative morbidity and mortality. Prehabilitation is a potential intervention for optimizing postoperative outcomes in frail patients. We studied the impact of a prehabilitation program on length of stay (LOS) in frail elderly patients undergoing elective surgery.

Opposite asymmetry in visual perception of humans and macaques.

In human adults, visual perception varies throughout the visual field. Performance decreases with eccentricity and varies around polar angle. At isoeccentric locations, performance is typically higher along the horizontal than vertical meridian (horizontal-vertical asymmetry [HVA]) and along the lower than the upper vertical meridian (vertical meridian asymmetry [VMA]).
