Background: Surgical mortality data are collected routinely in high-income countries, yet virtually no low-or middle-income countries have outcome surveillance in place. The aim was prospectively to collect worldwide mortality data following emergency abdominal surgery, comparing findings across countries with a low, middle or high Human Development Index (HDI).Methods: This was a prospective, multicentre, cohort study. Self-selected hospitals performing emergency surgery submitted prespecified data for consecutive patients from at least one 2-week interval during July to December 2014. Postoperative mortality was analysed by hierarchical multivariable logistic regression.

Pregnancy blocking in M. agrestis was associated with a rapid degeneration of CL, growth of follicles, a loss of embryos and return of the uterus to its non-pregnant state, and a return to cornified vaginal smears. These results are discussed in relation to the proposal that the immediate cause of pregnancy block is a failure of prolactin secretion resulting in a failure of CL function.

Splenectomized patients are at risk of overwhelming infection and are advised to take life-long prophylactic oral penicillin. Compliance studies have not been published for adults in this situation. We used a standard biological assay to detect penicillin in the urine of 58 splenectomized patients. 24 (42%) patients had evidence of penicillin in their urine. Patients' sex, age, years from splenectomy and underlying diagnosis were not important factors in identifying good or poor compliance. Since 58% of patients did not take their penicillin on the day studied, we need to consider alternative strategies of antibiotic use and patient education.
