We compared survival and outcomes in process of care in female versus male infants born ≤32 weeks gestational age (GA). Data were obtained from the Alere database for infants born ≤32 weeks GA. Females were compared with males for demographics, complications, and care processes. Univariate and multivariate analysis was conducted using chi-square analysis, analysis of variance, or logistic regression. Of the infants included, 6086 female and 6721 males were included. Mean GA did not differ, males were born larger than females, and females were more likely to be born SGA. Males received more surfactant, developed more CLD, received more steroids, and more often required oxygen at discharge. Females were more likely to develop a patent ductus arteriosus. After controlling for body weight, GA, and small-for-GA status, females were more likely to survive (95.4% versus 93.6%, odds ratio 1.63, P < 0.01). Male sex did not play a role in other processes of care except for weaning to a crib. Male infants born ≤32 weeks GA have a decreased rate of survival and an increased rate of respiratory morbidity in spite of higher birth weight distributions. Sex did not play a role in other processes of care.

The objective of this study was to obtain pilot data on which to judge the feasibility and sample size needed for a future comparative-effectiveness trial of platelet transfusions in the NICU. We conducted a limited-scope pilot trial in which neonates were randomized to receive platelet transfusions based on platelet mass vs. platelet count, using preset "transfusion-trigger" values. Analysis included parental consent rate, number of platelet transfusions given, bleeding episodes recorded, and mortality rate. Statistical analysis included ANOVA and Chi-square. A convenience sample of 30 were randomized; 15 per group. No differences were found between groups in gestational age, birth weight, race, gender or clinical diagnoses. The study consent rate was 52% (30/58). No differences were found in number of platelet transfusions received, bleeding episodes, or mortality. Lack of a trend in transfusion-reduction resulted in inability to estimate the number needed in a future comparative-effectiveness trial. Using platelet mass, rather than platelet count, for a NICU platelet transfusion trigger is feasible. However, any future comparative-effectiveness trial, testing the hypothesis that a platelet mass-based trigger reduces the transfusion rate will likely require a very large sample size.

We report the case of a 52-year-old male who underwent total orthotopic heart transplantation for end-stage ischemic cardiomyopathy. The postoperative course was complicated by acute intestinal infarction which was diagnosed after surgical exploration, and treated with a subtotal colectomy with Brooke ileostomy and closure of the distal sigmoid three days posttransplant. The patient survived with nutritional support and broad antibiotic prophylaxis. Review of the literature on acute abdominal complications after operations involving cardiopulmonary bypass suggests that such complications are usually fatal. Detection and diagnosis may be obscured and treatment complicated by immunosuppression after cardiac transplantation. Because of the poor prognosis without appropriate management, a high level of suspicion, early and aggressive diagnostic measures, and swift surgical intervention are essential to survival.
