Evidence of perturbations of the cytokine network in preterm labor.
Intraamniotic inflammation/infection is the only mechanism of disease with persuasive evidence of causality for spontaneous preterm labor/delivery. Previous studies about the behavior of cytokines in preterm labor have been largely based on the analysis of the behavior of each protein independently. Emerging evidence indicates that the study of biologic networks can provide insight into the pathobiology of disease and improve biomarker discovery. The goal of this study was to characterize the inflammatory-related protein network in the amniotic fluid of patients with preterm labor. ⋯ We report for the first time an analysis of the inflammatory-related protein network in spontaneous preterm labor. Patients with preterm labor and microbial-associated intraamniotic inflammation had more coordinated amniotic fluid inflammatory-related proteins than either those with sterile intraamniotic inflammation or those without intraamniotic inflammation. The correlations were also stronger in patients with sterile intraamniotic inflammation than in those without intraamniotic inflammation. The findings herein could be of value in the development of biomarkers of preterm labor.

Randomized Controlled Trial Multicenter StudyDoes 17-alpha hydroxyprogesterone caproate prevent recurrent preterm birth in obese women?
We sought to determine if maternal weight or body mass index (BMI) modifies the effectiveness of 17-alpha hydroxyprogesterone caproate (17OHP-C). ⋯ The effectiveness of 17OHP-C is modified by maternal weight and BMI, and treatment does not appear to reduce the rate of PTB in women who are obese or have a weight >165 lb. This finding may be due to subtherapeutic serum levels in women with increased BMI or weight. Studies of adjusted-dose 17OHP-C in women who are obese or who weigh >165 lb are warranted, and current recommendations regarding the uniform use of 17OHP-C regardless of maternal BMI and weight may deserve reassessment.

Multimodal nociceptive mechanisms underlying chronic pelvic pain.
We sought to evaluate candidate mechanisms underlying the pelvic floor dysfunction in women with chronic pelvic pain (CPP) and/or painful bladder syndrome (PBS)/interstitial cystitis. Notably, prior studies have not consistently controlled for potential confounding by psychological or anatomical factors. ⋯ Both experimental assessment of pelvic floor pain thresholds and measurement of sustained pain are independently associated with pelvic pain phenotypes. These findings suggest systematic clinical assessment of the time course of provoked pain symptoms, which occurs over seconds for mechanical pain thresholds vs minutes for aftersensation pain, would be helpful in identifying the fundamental mechanisms of pelvic floor pain. Longitudinal studies of therapies differentially targeting these discrete mechanisms are needed to confirm their clinical significance.

Burnout and associated factors among members of the Society of Gynecologic Oncology.
Burnout is specific to the work domain and in physicians is indicative of emotional exhaustion, depersonalization in relationships with coworkers and detachment from patients, and a sense of inadequacy or low personal accomplishment. The purpose of this study was to determine the burnout rate among gynecologic oncologists and evaluate other personal, professional, and psychosocial factors associated with this condition. ⋯ Burnout is a significant problem associated with psychosocial distress and lower levels of career satisfaction in gynecologic oncologists. Burnout in obstetrics-gynecology and gynecologic oncology is of particular concern as young age and female gender are often identified as risk factors for this significant problem. Interventions targeted at improving quality of life, treatment of depression, or alcohol abuse may have an impact on burnout. However, significant barriers may exist as 44.5% of respondents in this study reported that they would be reluctant to seek medical care for depression, substance use, or other mental health issues due to concerns about their medical license.

Effect of stage of initial labor dystocia on vaginal birth after cesarean success.
The objective of the study was to examine whether the stage of labor dystocia causing a primary cesarean delivery (CD) affects a trial of labor after cesarean (TOLAC) success. ⋯ Nearly half of women with a history of primary CD for labor dystocia will achieve VBAC. Women with a history of second-stage labor dystocia have a slightly higher VBAC rate, seen to a statistically significant degree in those without a history of prior VD. TOLAC should be offered to all eligible women and should not be discouraged in women with a prior second-stage arrest.
