BACKGROUND: Preterm birth is the leading cause of child mortality under 5 years of age. Temporal trends in preterm birth rates are highly heterogeneous among countries and little information exists for China. To address this data gap, we investigated annual changes in preterm birth incidence rate and explored potential determinants of these changes in Shenzhen, China. METHODS: A total of 1.4 million live births, during 2003-2012, were included from the Shenzhen birth registry...

Since pathologies and complications occurring during pregnancy and/or during labour may cause adverse outcomes for both newborns and mothers, there is a growing interest in metabolomic applications on pregnancy investigation. In fact, metabolomics has proved to be an efficient strategy for the description of several perinatal conditions. In particular, this study focuses on premature rupture of membranes (PROM) in pregnancy at term. For this project, urine samples were collected at three different clinical conditions: out of labour before PROM occurrence (Ph1), out of labour with PROM (Ph2), and during labour with PROM (Ph3)...

Group B streptococcus (GBS) is one of the severe pathogenic bacteria during the perinatal period, both on pregnant women and newborns. GBS infection may lead to pneumonia, septicemia, meningitis or other severe disease, even death in neonates. Although only 1%-2% infections will develop into GBS disease among the neonates, the etiological mechanism of which is worth researching. This review summarizes the possible factors related to GBS infection or occurrence of the disease, including the risk in gestation period (for example, colonization of GBS on vagina of pregnant women, preterm birth or premature rupture of fetal membranes and so on), related pathogens (bacteria strains, loads or virulence), immune level (inflammatory factor or neutralizing anticytokine auto-Abs), gene defect or primary immunodeficiencies of the hosts...

BACKGROUND: Gonorrhoea is a sexually transmitted infection that is caused by Neisseria gonorrhoeae, and is a major public health challenge today. N gonorrhoeae can be transmitted from the mother's genital tract to the newborn during birth, and can cause gonococcal ophthalmia neonatorum as well as systemic neonatal infections. It can also cause endometritis and pelvic sepsis in the mother. This review updates and replaces an earlier Cochrane Review on antibiotics for treating this infectious condition...

OBJECTIVE: Progesterone supplementation prevents preterm birth (PTB) in some high-risk women, but its mechanism of action is unknown. One-third of PTB is associated with preterm premature rupture of membranes (PPROMs). We have previously shown that progesterone inhibits basal and Tumor Necrosis Factor (TNF) α-induced apoptosis in an explant model of human fetal membranes. This study investigates the molecular mechanisms responsible for progesterone-mediated inhibition of apoptosis in fetal membranes...

Passiflora incarnata is marketed in many countries as anxiolytic herbal supplement. Herbal medicines are natural products, but it doesn't mean they are always safe, especially during pregnancy. Passiflora incarnata extract was not teratogenic in experimental studies. However, there are no data available on possible effects on human pregnancy. Here we report five pregnant women with depression and/or anxiety who used passiflora incarnata in pregnancy. We observed one pregnancy resulting in neonatal death, two pregnancies with premature rupture of membranes, two infants with meconium aspiration syndrome and one infant with persistent pulmonary hypertension...

The aim of this study was to review fetoscopic laser photocoagulation (FLP), which ablates placental vascular anastomoses to treat twin-twin transfusion syndrome (TTTS). A review of studies reporting on the procedures, outcomes, complications and nonconventional applications of FLP for TTTS was conducted. FLP has been established as the primary treatment for monochorionic twin pregnancy associated with TTTS at 16-26 weeks. FLP is the only therapy that directly addresses the underlying pathophysiology. The recent technique modification of FLP, referred to as the 'Solomon technique', induces selective coagulation to connect the anastomoses ablation sites and has been introduced to reduce residual anastomoses...

The study was performed on pregnant women with a gestational age of 26-32 weeks of pregnancy, who had been admitted to the hospital with a confirmed diagnosis of premature rupture of membranes. In all eligible women, ultrasounds were performed for the evaluation of amniotic fluid index. Then, the women were divided into two groups according to amniotic fluid index of ≥5 cm and <5 cm. These women were followed and monitored up to delivery. The women of the two groups did not have significant difference between them according to age, gestational age at the time of ruptured membrane, body mass index, gravidity, parity, gestational age at delivery and route of delivery...

Diabetic macroangiopathy - a specific form of accelerated atherosclerosis - is characterized by intra-plaque new vessel formation due to excessive/abnormal neovasculogenesis and angiogenesis, increased vascular permeability of the capillary vessels, and tissue edema, resulting in frequent atherosclerotic plaque hemorrhage and plaque rupture. Mechanisms that may explain the premature and rapidly progressive nature of atherosclerosis in diabetes are multiple, and to a large extent still unclear. However, mechanisms related to hyperglycemia certainly play an important role...

Trichomonas vaginalis is a very common, sexually transmitted, infection that may sometimes be asymptomatic or cause vaginitis and urethritis. Recently, it has been associated with adverse obstetric outcomes such as preterm delivery, low birth weight and premature rupture of membranes. Trichomonas vaginalis can be vertically transmitted at birth. It has been found in pharynx and low respiratory tract of neonates with respiratory disease. It has also been involved in some cases of intellectual disability. The recommended treatment is a 2g metronidazole oral single dose, even for asymptomatic patients...

Congenital Zika virus (ZIKV) infection impacts fetal development and pregnancy outcomes. We infected a pregnant rhesus macaque with a Puerto Rican ZIKV isolate in the first trimester. The pregnancy was complicated by preterm premature rupture of membranes (PPROM), intraamniotic bacterial infection and fetal demise 49 days post infection (gestational day 95). Significant pathology at the maternal-fetal interface included acute chorioamnionitis, placental infarcts, and leukocytoclastic vasculitis of the myometrial radial arteries...
