Cesarean deliveries and maternal-infant HIV transmission: results from a prospective study in South Africa.
Data from a prospective study undertaken at an urban hospital in Durban, South Africa, were used to investigate associations between maternal-infant HIV transmission, mode of delivery, and specific circumstances of cesarean deliveries. A total of 141 children of HIV-infected women were followed until the children were 15 months of age to determine their HIV status. supplementary data were collected from obstetric records, masked to the HIV status of the children. ⋯ Singleton cesarean deliveries without concurrent obstetric complications had lower rates of transmission than did vaginal deliveries (OR, 0.20; 95% CI, 0.04-0.94). These results suggest that certain intrapartum events may modify the risk of HIV transmission and highlight the importance of collecting more detailed intrapartum information in order to clarify the route by which mode of delivery may be associated with maternal-infant HIV transmission.

Perinatal morbidity and mortality in offspring of diabetic mothers in Qatif, Saudi Arabia.
Diabetic mothers and their offspring were prospectively studied. Perinatal and neonatal morbidity and mortality data were analysed. Out of 11,677 deliveries in the hospital, 133 (1.14%) were delivered by diabetic mothers. ⋯ Poor maternal diabetic control resulted in high perinatal morbidity and mortality in the offspring. In order to improve the outcome in offspring of diabetic mothers in Qatif and probably Saudi Arabia as a whole, health education and improved care of the diabetic mothers during pregnancy urgently needed. This may be true of other developing countries where data on diabetes in pregnancy are scarce.

During a 5-month study period, 323 of 863 (37.5%) children below 5 years of age admitted to Shongwe Mission Hospital in rural South Africa were malnourished, two-thirds severely so. The incidence of bacteraemia in malnourished children was 9.6%, 11.8% in those severely malnourished and 5.8% in nutritional dwarfs. The predominant organisms retrieved were Gram-negative enteric bacilli (48.5%). ⋯ The case fatality rate of severely malnourished bacteraemic children was 20.8%. In malnutrition categories overall, the case fatality rate for bacteraemic children (22.6%) was significantly greater than in those without bacteraemia (9.3%). In hospitals with limited resources, full identification of bacteria may not be necessary, provided that regular surveillance for emerging resistance is conducted.

Alterations in the myocardial β-adrenergic system during experimental endotoxemia.
In this study to investigate whether β-adrenergic receptor systems in the heart are impaired during endotoxemia, we examined two models of septic shock in rats, each of which has a different time course for the shock state. Male Wistar rats were divided into two groups: (1) the LPS (lipopolysaccharide) iv group (Escherichia coli endotoxin 1.0 mg·kg(-1) iv bolus administration), and (2) the CLP (cecal ligation and puncture model) group. As a control group for each model, a 0.9% saline injection group and a sham-operated group were also prepared. ⋯ The alteration in hemodynamics of septic-shock rats observed in this study was linked to the change in heart β-receptor density rather than the change in plasma CA. These observations suggested that the alterations which occur in the β-receptor system during endotoxemia depend upon the model of animal sepsis that is employed, and the time course of the septic-shock state. These alterations in the β-adrenergic system are thought to cause myocardial dysfunction during endotoxemia.
