Purpose Elderly patients are vulnerable to malnutrition and we have started systematic screening for preoperative malnutrition risk in our institution. This study aims to determine the prevalence and risk factors of preoperative malnutrition risk among elderly surgical patients, and its impact on surgical outcomes. Methods In this retrospective cohort study of patients C 65 yr old undergoing elective surgery, we recorded demographics, medications, preoperative effort tolerance, Malnutrition Universal Screening Tool (MUST) score, American Society of Anesthesiologists physical status (ASA), Charlson Comorbidity Index (CCI), and Edmonton Frailty Score (EFS). Postoperative complications based on This article is accompanied by an editorial. Please see Can J Anesth 2021; this issue.
Renal complications from snakebite result in high mortality and morbidity. Acute kidney injury (AKI) occurs in 5–30% of cases. Renal manifestation could include acute tubular necrosis, cortical necrosis, interstitial nephritis, glomerulonephritis, and vasculitis. We present a case of thrombotic microangiopathy (TMA) resulting in renal cortical necrosis. Renal biopsy showed fibrin thrombi in glomeruli and arterioles with cortical necrosis. Our patient progressed to end-stage renal disease.
