Urinary Incontinence, Body Mass Index, and Physical Activity in Young Women
Current evidence suggests that overweight and obesity are important risk factors for urinary incontinence in women. However, little is known about the relationships between body mass index (BMI), physical activity and urinary incontinence in women in their 20s.

Utility of Follow up Cervical Length Screening in Low Risk Women with Cervical Length 26-29mm
In women with a prior preterm birth, a protocol for serial cervical length screening has been studied and recommended for identification and treatment of short cervix. Cervical length screening has been suggested for low risk singletons in order to treat short cervix vaginal progesterone and reduce preterm birth. However, specific protocols for single versus serial cervical length ultrasound in this population are not established. Cost effectiveness of universal cervical length screening depends on the cost of screening; follow up of borderline measurements can contribute to increased costs with uncertain benefit. (Source:...

Urban-Rural Differences in Pregnancy-Related Deaths, United States, 2011 –2016
The U.S. pregnancy-related mortality ratio has not improved over the past decade and includes striking disparities by race/ethnicity and by state. Understanding differences in pregnancy-related mortality across and within urban and rural areas can guide the development of interventions for preventing future pregnancy-related deaths.

Unfolding the pathophysiology of congenital thrombotic thrombocytopenic purpura in pregnancy: Lessons from a cluster of familial cases
Thrombotic Thrombocytopenic Purpura (TTP), a rare, potentially life-threatening thrombotic microangiopathy, manifests as both congenital (cTTP) and acquired forms. It is caused by the absence of or severe depletion in a disintegrin and metalloproteinase with thrombospondin motifs 13 (ADAMTS13) protease leading to the accumulation of ultra large von Willebrand Factor (vWF) multimers and extensive platelet adhesion and clumping, which can ultimately result in severe secondary end-organ damage. Pregnancy can provoke or exacerbate TTP leading to maternal and fetal complications. (Source: American Journal of Obstetrics and Gynecology)

Predicting obstetric anal sphincter injuries (OASIS) in patients who undergo vaginal birth after cesarean section (VBAC).
Women with a history of prior cesarean section must weigh the numerous potential risks and benefits of elective repeat cesarean section or trial of labor (TOLAC). One important risk of vaginal delivery is obstetric anal sphincter injury (OASIS), and it occurs at higher rates among women undergoing vaginal birth after cesarean (VBAC). However, the risk of OASIS is not routinely included in TOLAC counseling and there is no tool available to risk stratify OASIS among women undergoing VBAC.

Genital tuberculosis screening at an academic fertility center in the United States
We read with great interest the article published by Tal et  al1 which aimed to determine the prevalence of female genital tuberculosis (FGTB) among infertile patients presenting to an academic fertility center. In their prospective cohort study, the authors found that a higher proportion of patients with positive QuantiFERON Gold test were foreign born and had recurrent pregnancy loss and Asherman syndrome compared with those who had a negative test. They concluded that multiple diagnostic modalities including endometrial sampling are required to diagnose FGTB in infertile patients, and they recommend screening of al...

Syncytiotrophoblast stress in preeclampsia: the convergence point for multiple pathways
Preeclampsia evolves in 2 stages: a placental problem that generates signals to the mother to cause a range of responses that comprise the second stage (preeclampsia syndrome). The first stage of early-onset preeclampsia is poor placentation, which we here call malplacentation. The spiral arteries are incompletely remodeled, leading to later placental malperfusion, relatively early in the second half of pregnancy. The long duration of the first stage (several months) is unsurprisingly associated with fetal growth restriction. (Source: American Journal of Obstetrics and Gynecology)
