Preterm birth (PTB), which occurs in about 12% of pregnancies worldwide, is the main cause of neonatal morbidity and mortality. Symptomatic treatment of pregnancies presenting in preterm labor with corticosteroids and antibiotics has improved neonatal outcomes but has not reduced the incidence of PTB. Evidence suggests that the rate of PTB may be reduced by the prophylactic use of progesterone in women with a previous history of preterm delivery and in those with a short cervical length identified by routine transvaginal ultrasound. This review summarizes the evidence (level A evidence) of the effectiveness of progesterone on the rate of PTB.

Lateralization of Neural Speech Discrimination at Birth Is a Predictor for Later Language Development.
Dev Sci

Newborns are able to neurally discriminate between speech and nonspeech right after birth. To date it remains unknown whether this early speech discrimination and the underlying neural language network is associated with later language development. Preterm-born children are an interesting cohort to investigate this relationship, as previous studies have shown that preterm-born neonates exhibit alterations of speech processing and have a greater risk of later language deficits.

Background: Periviable infants are a highly vulnerable neonatal group, and their survival rates are considerably affected by patient-, caregiver-, and institution-level factors, exhibiting wide variability across different income countries and time periods. This study aims to systematically review the literature on the survival rates of periviable infants and compare rates among countries with varied income levels and across different time periods.
Methods: Comprehensive searches were conducted across MEDLINE, Embase, CENTRAL, and Web of Science.
Thymol and Carvacrol as Potential Tocolytic and Anti-inflammatory Agents in Pregnant Rat Uterus.
Curr Mol Pharmacol

Área Académica de Medicina del Instituto de Ciencias de la Salud, Universidad Autónoma del Estado de Hidalgo, Pachuca, Hidalgo, México.
Introduction: This work aimed to evaluate the anti-inflammatory and myorelaxant effect of thymol (TM) and carvacrol (CAR) in the pregnant rat uterus. Both compounds exhibit considerable antimicrobial, antispasmodic, and anti-inflammatory effects and due to these properties, they were studied in this in vitro model of premature birth induced by infection.
Method: All uterine tissues were studied in uterine contraction tests to determine the inhibitory effect of TM, CAR (10, 56, 100, 150, and 230 μM), and nifedipine (a calcium channel antagonist) on phasic and tonic contraction induced by electro- and pharmacomechanical stimuli.
Objectives: The objective of this study was to identify factors associated with in-hospital deaths of newborns admitted to a special care newborn unit (SCANU) in southern Bangladesh.
Design: Retrospective cohort.
Setting: SCANU of Patuakhali Medical College Hospital, Patuakhali, Bangladesh.

Introduction: Medical progress has significantly improved the survival rates of very preterm-born infants in recent decades. Nevertheless, these infants are still at increased risk for long-term impairments as compared with term-born infants. While the homecoming of a preterm-born infant is long-awaited and brings relief to families, it also marks the end of intensive monitoring and highly specialised professional care.
