The incidence of transfusion and associated risk factors in pelvic reconstructive surgery.
Almost 400,000 female pelvic reconstructive operations were performed in 2010 for urinary incontinence and pelvic organ prolapse in the United States, and it is likely that this will continue to increase each year. There is a lack of population-based data evaluating the risk of blood transfusion after urogynecologic procedures. ⋯ Transfusion after pelvic reconstructive surgery is uncommon. The variables associated with transfusion are preoperative hematocrit <30%, American Society of Anesthesiologists class, bleeding disorders, nonwhite race, Hispanic ethnicity, and concomitant hysterectomy. Recognition of these factors can help guide preoperative counseling regarding transfusion risk after pelvic reconstructive surgery and individualize preoperative preparation.

Aspirin for Evidence-Based Preeclampsia Prevention trial: effect of aspirin in prevention of preterm preeclampsia in subgroups of women according to their characteristics and medical and obstetrical history.
The Combined Multimarker Screening and Randomized Patient Treatment with Aspirin for Evidence-Based Preeclampsia Prevention trial demonstrated that in women who were at high risk for preterm preeclampsia with delivery at <37 weeks' gestation identified by screening by means of an algorithm that combines maternal factors and biomarkers at 11-13 weeks' gestation, aspirin administration from 11 to 14 until 36 weeks' gestation was associated with a significant reduction in the incidence of preterm preeclampsia (odds ratio 0.38; 95% confidence interval, 0.20 to 0.74; P=0.004). ⋯ The beneficial effect of aspirin in the prevention of preterm preeclampsia may not apply in pregnancies with chronic hypertension. There was no evidence of heterogeneity in the aspirin effect in subgroups defined according to maternal characteristics and obstetrical history.

Heavy menstrual bleeding affects up to one third of women in the United States, resulting in a reduced quality of life and significant cost to the health care system. Multiple treatment options exist, offering different potential for symptom control at highly variable initial costs, but the relative value of these treatment options is unknown. ⋯ Comparing all trade-offs associated with 4 possible treatments of heavy menstrual bleeding, the levonorgestrel-releasing intrauterine system was superior to both hysterectomy and endometrial ablation in terms of cost and quality of life. Hysterectomy is associated with a superior quality of life and fewer complications than either type of ablation but at a higher cost. For women who are unwilling or unable to choose the levonorgestrel-releasing intrauterine system as a first-course treatment for heavy menstrual bleeding, consideration of cost, procedure-specific complications, and patient preferences can guide the decision between hysterectomy and ablation.

First sacral nerve and anterior longitudinal ligament anatomy: clinical applications during sacrocolpopexy.
The recommended location of graft attachment during sacrocolpopexy is at or below the sacral promontory on the anterior surface of the first sacral vertebra. Graft fixation below the sacral promontory may potentially involve the first sacral nerve. ⋯ Awareness of the first sacral nerve position, approximately 2.5 cm below the midpoint of the sacral promontory and 2 cm to the right of midline, should help anticipate and avoid somatic nerve injury during sacrocolpopexy. Knowledge of the approximate 2-mm thickness of the anterior longitudinal ligament should help reduce risk of discitis and osteomyelitis, especially when graft is affixed above the level of the sacral promontory.

Evidence that children born at early term (37-38 6/7 weeks) are at increased risk for diabetes and obesity-related disorders.
Prematurity is known to be associated with high rates of endocrine and metabolic complications in the offspring. Offspring born early term (37-38 6/7 weeks' gestation) were also shown to exhibit long-term morbidity resembling that of late preterm, in several health categories. ⋯ Deliveries occurring at early term are associated with higher rates of long-term pediatric endocrine and metabolic morbidity of the offspring as compared with deliveries occurring at a later gestational age. This association may be due to absence of full maturity of the hormonal axis in early term neonates or, alternatively, suggest an underlying fetal endocrine dysfunction as the initial mechanism responsible for spontaneous early term delivery.
