Increased risk of peripartum perinatal mortality in unplanned births outside an institution: a retrospective population-based study.
Births in midwife-led institutions may reduce the frequency of medical interventions and provide cost-effective care, while larger institutions offer medically and technically advanced obstetric care. Unplanned births outside an institution and intrapartum stillbirths have frequently been excluded in previous studies on adverse outcomes by place of birth. ⋯ Unplanned birth outside an institution was associated with increased peripartum mortality and with long travel time to obstetric institutions. Structural determinants have an important impact on perinatal health in high-income countries and also for low-risk births. The results show the importance of skilled birth attendance and warrant attention from clinicians and policy makers to negative consequences of reduced access to institutions.

Randomized Controlled TrialA randomized, double-blinded, controlled trial of the effects of fluid rate and/or presence of dextrose in intravenous fluids on the labor course of nulliparas.
Prolonged labor has been demonstrated to increase adverse maternal and neonatal outcome. A practice that may decrease the risk of prolonged labor is the modification of fluid intake during labor. ⋯ There is no difference in length of labor or delivery outcomes when comparing high-dose intravenous fluids, addition of dextrose, or use of high-dose intravenous fluids with dextrose in nulliparous women who present in active labor.

Overview of high-risk medical device recalls in obstetrics and gynecology from 2002 through 2016: implications for device safety.
The field of women's health has endured numerous recent controversies involving medical devices such as pelvic meshes, laparoscopic morcellators, and a hysteroscopic sterilization device. With the recent passage of the 21st Century Cures Act, new legislation will change how the Food and Drug Administration regulates medical devices. Given these controversies and new changes, we investigated high-risk, class I recalls in women's health from 2002 through 2016. ⋯ Class I medical device recalls are rare but serious events. Most recalled devices in women's health had minimal preapproval regulation and were recalled due to both premarketing and postmarketing reasons. Future regulatory efforts to improve postmarketing surveillance may mitigate the potential impact and frequency of class I recalls, but do not replace the need for a higher burden of proof for both safety and efficacy prior to medical device approval.

Balloon removal after fetoscopic endoluminal tracheal occlusion for congenital diaphragmatic hernia.
Isolated congenital diaphragmatic hernia defect allows viscera to herniate into the chest, competing for space with the developing lungs. At birth, pulmonary hypoplasia leads to respiratory insufficiency and persistent pulmonary hypertension that is lethal in up to 30% of patients. Antenatal measurement of lung size and liver herniation can predict survival after birth. Prenatal intervention aims at stimulating lung development, clinically achieved by percutaneous fetal endoscopic tracheal occlusion under local anesthesia. This in utero treatment requires a second intervention to reestablish the airway, either before birth or at delivery. ⋯ In these fetal treatment centers, the balloon could always be removed successfully. In 90% this was in utero, with the use of fetoscopy preferred over ultrasound-guided puncture. Ex utero removal was a fall-back procedure. In utero removal does not seem to precipitate immediate membrane rupture, labor, or delivery, although the design of the study did not allow for a formal conclusion. For fetoscopic removals, the introduction of a stylet facilitated retrieval. Successful removal may rely on a permanently prepared team with expertise in all possible techniques.

Multicenter StudyA multicenter prospective study of neonatal outcomes at less than 32 weeks associated with indications for maternal admission and delivery.
Counseling for patients with impending premature delivery traditionally has been 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. ⋯ Studies of many single factors related to the indications for preterm delivery have been shown to be associated with adverse neonatal outcome. In this study evaluating all of the most frequent indications, however, we found only suspected intrauterine growth restriction as an indication for admission and delivery was found to be so. Thus, it seems that in almost all situations counseling patients can be based primarily on gestational age along with other factors including estimated fetal weight, sex, race, plurality, and completion of a course of antenatal corticosteroids.
