Long noncoding RNA (lncRNA) has been proven to be involved in many biological processes in ovarian cancer (OC). However, the mechanism still remains unknown. In this study, we screened significantly downregulated NBAT-1, which has been proven to play a significant role in breast cancer, clear cell renal cell carcinoma, and neuroblastoma, but not in OC, in two independent datasets with relatively more samples (GSE18520 and GSE38666) from Gene Expression Omnibus. We found that lncRNA NBAT-1 was obviously downregulated in OC tissue compared to normal ovarian tissue (P<0...

Concerns have been raised about the health and development of children conceived by assisted reproductive technologies (ART) since 1978. Controversially, ART has been linked with adverse obstetric and perinatal outcomes, an increased risk of birth defects, cancers, and growth and development disorders. Emerging evidence suggests that ART treatment may also predispose individuals to an increased risk of chronic ageing related diseases such as obesity, type 2 diabetes and cardiovascular disease. This review will summarize the available evidence on the short-term and long-term health outcomes of ART singletons, as multiple pregnancies after multiple embryos transfer, are associated with low birth weight and preterm delivery, which can separately increase risk of adverse postnatal outcomes, and impact long-term health...

Long noncoding RNAs (lncRNAs) have recently emerged as pivotal regulators that govern fundamental biological processes and disease pathogenesis. LncRNA MNX1-AS1 has been reported to promote cell proliferation and invasion in gallbladder cancer, but its biological role and regulatory mechanism in ovarian cancer are poorly defined. In this study, it was found that higher expression of lncRNA MNX1-AS1 is closely associated with International Federation of Gynecology and Obstetrics stage and lymphatic metastasis in ovarian cancer patients...

Despite years of research, miscarriage, particularly when recurrent, continues to pose a medical challenge. An embryo chromosomal error is responsible for 50-60% of recurrent cases; however, up to 30-50% remains an enigma. Successful pregnancy involves different maternal physiologic changes and certain complex interactions between the fetus and the mother by cytokines, angiogenic mediators and hormones. To date, research lines have focused on genetic and epigenetic polymorphisms related mainly to immune response and inflammatory mediators, and have yielded a significant relationship between recurrent miscarriage and immune mechanisms...

The "obstetrical dilemma" posits that increases in birth canal dimensions during hominin evolution were constrained by mechanical factors associated with bipedal gait. This model has recently been challenged, in part on the basis of experimental data showing little association between pelvic and proximal femoral dimensions and locomotor costs among human experimental subjects. However, complete rejection of the model is premature, for two reasons: (1) it is difficult to extrapolate experimental results to naturalistic conditions and the much more varied body form and possibly locomotor style of early hominins...

Cardiotocography (CTG) is a technique used to monitor intrapartum fetal condition and is one of the most common obstetric procedures. Second line methods of fetal monitoring have been developed in an attempt to reduce unnecessary interventions due to continuous cardiotocography and to better identify fetuses at risk of intrapartum asphyxia. The acid-base balance of the fetus is evaluated by fetal blood scalp samples, the modification of the myocardial oxygenation by the fetal ECG ST-segment analysis (STAN) and the autonomic nervous system by the power spectral analysis of the fetal heart variability...

Cervical cancer is the second most common gynecological cancer worldwide and remains as one of the leading causes of cancer-related death among women. Despite great progress in the treatment of cervical cancer, the 5-year overall survival rate for patients with this disease remains unsatisfactory. Over the past decade, an increasing number of studies indicate a central role for microRNAs in the initiation and progression of cervical cancer. microRNA‑329-3p (miR-329-3p) has been studied in many types of human cancer; however, the expression level, biological role and the underlying mechanism of miR-329-3p in cervical cancer has not yet been investigated...

Systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) are the most prevalent autoimmune rheumatic diseases, predominantly occurring in women during childbearing years. Research has focused on assessing the risk of immediate complications during SLE and RA pregnancies, with studies documenting a higher risk of adverse obstetric outcomes, such as preterm births and infants small for gestational age. Until recently, little was known regarding the long-term health of children born to affected women. We present a review of the current evidence regarding the risk of adverse health outcomes in SLE and RA offspring, and potential mechanisms involved in their pathogenesis...

Aspirin is one of the most frequently used and cheapest drugs in medicine. It belongs to the non-steroidal anti-inflammatory drugs with a wide range of pharmacological activities, including analgesic, antipyretic, and antiplatelet properties. Currently, it is accepted to prescribe a low dose of aspirin to pregnant women who are at high risk of preeclampsia (PE) because it reduces the onset of this complication. Another pregnancy alteration in which a low dose of aspirin is recommended is the obstetric antiphospholipid syndrome (APS)...

José María Ceriani Cernadas
For at least over 200 years, multiple controversies have arisen around the timing of umbilical cord clamping. In the past decades, early cord clamping (within the first 15 seconds) had markedly prevailed. Only in the 21st century, randomized controlled trials have demonstrated the benefits of delayed cord clamping (at 2-3 minutes). Delayed cord clamping has been practiced in obstetrics based on the recommendations made by scientific societies and in systematic reviews, which have provided solid evidence to support this practice in term infants...
