Deregulation in uterine contractility can cause common pathological disorders of the female reproductive system, including preterm labor, infertility, inappropriate implantation, and irregular menstrual cycle. A better understanding of human myometrium contractility is essential to designing and testing interventions for these important clinical problems. Robust studies on the physiology of human uterine contractions require in vitro models, utilizing a human source. Importantly, uterine contractility is a three-dimensionally (3D)-coordinated phenomenon and should be studied in a 3D environment...

Objective Risk factors for placental abruption have changed, but there has not been an updated systematic review investigating outcomes. Methods We searched PubMed, EMBASE, Web of Science, SCOPUS, and CINAHL for publications from January 1, 2005 through December 31, 2016. We reviewed English-language publications reporting estimated incidence and/or risk factors for maternal, labor, delivery, and perinatal outcomes associated with abruption. We excluded case studies, conference abstracts, and studies that lacked a referent/comparison group or did not clearly characterize placental abruption...

Almost every part of our body has a coevolved microbial community. The expressed microbial genes comprise the various microbiomes that play important roles in normal physiology and development. The various microbiomes are separate, yet often connected, with the species composition of one affecting others. The female reproductive system microbiomes (eg, vaginal, placental, and mammary/milk) remain less well explored than the gut microbiome although they comprise a large proportion of the female microbial network...

In the United States, preterm delivery is the leading cause of neonatal morbidity and is the most common reason for hospitalization during pregnancy. The rate of preterm delivery (before 37 weeks' gestation) has been declining since 2007. Clinical diagnosis of preterm labor is made if there are regular contractions and concomitant cervical change. Less than 10% of women with a clinical diagnosis of preterm labor will deliver within seven days of initial presentation. Women with a history of spontaneous preterm delivery are 1...

The aim of this review is to present the beliefs related to sexual activity during pregnancy. We identified 13 studies (3122 participants). The main positive beliefs about sex in pregnancy were that it makes labor easier, promotes marital harmony, prevents infidelity and improves fetal well-being. Negative beliefs were more frequent; they were that sex could harm the unborn child (cause injuries, miscarriage or fetal infection) and endanger the pregnancy or maternal health (cause membrane rupture, bleeding, preterm labor and maternal infection)...

It is estimated that six million perinatal deaths occur every year worldwide, with premature birth being the main cause. Scientific evidence has shown that there is an association between periodontal health during pregnancy and adverse outcomes of labor, although interventional studies based on the treatment of periodontitis have failed to document an impact on reducing the incidence of preterm birth (PB) or low birth weight (LBW). Two pathogenic mechanisms have been proposed to explain this association. The direct pathway is based on the presence of gram-negative anaerobic bacteremia originating in the gingival biofilm, whereas the indirect pathway involves the production of pro-inflammatory markers which enter the bloodstream from the gingival submucosa...

Hypoxic-ischemic encephalopathy (HIE) due to lack of oxygen is a debilitating disorder experienced by a significant number of preterm infants during birth. Studies show that the brain undergoes different phases of injury following hypoxic insult, but the first 6-8 hours (known as a latent phase) are the key to treatment efficacy. Cerebral hypothermia is one known treatment, and for it to be effective it must be started during the latent phase and continued for several days. In order to determine the effectiveness of treatment it is important to pinpoint the time of insult...

BACKGROUND: Counseling for patients with impending premature delivery has been traditionally based primarily on the projected gestational age at delivery. There are limited data regarding how the indications for the preterm birth affect the neonatal outcome and whether this issue should be taken into account in decisions regarding management and patient counseling. OBJECTIVE: We performed a prospective study of pregnancies resulting in premature delivery at less than 32 weeks to determine the influence of both the Indications for Admission and their associated Indications for Delivery on neonatal mortality and complications of prematurity...
