Effectiveness and safety of late midtrimester cervical cerclage.

Objectives: To evaluate the safety and effectiveness of late cervical cerclage performed beyond 17 weeks of gestation. The outcomes of interest were effectiveness of late cerclage in prolongation of pregnancy and evaluation of pregnancy outcome including maternal and fetal complications. Study design: A total of 30 patients underwent late cervical cerclage during the study period. Of them, two were twin pregnancies. A late cerclage was performed after the diagnosis of cervical shortening or dilatation in 20 patients. We performed a retrospective case series review. One case was lost to follow up (delivery in another medical center). Medical information was retrieved from all cases of patients who underwent a late cervical cerclage between the years 2010 and 2016 at the Soroka University Medical Center, a tertiary medical center. Continuous variables were expressed as mean ± standard deviation. Categorical variables were expressed as proportions. Results: The average gestational age at birth was 35 ± 5.1 weeks of gestation. The mean interval between cerclage and delivery in the study population was 17 ± 5.62 weeks. Nine cases (32.1%) resulted in preterm deliveries, three of them below 34 weeks of gestation (one twin pregnancy and two pregnancies diagnosed with cervical dilation prior to cerclage). Among all the preterm deliveries, there were four cases of preterm prelabor rupture of membranes (13.3%). Of the 28 deliveries, 24 women (85.7%) had a vaginal delivery, while four women (14.3%) underwent a cesarean section. No cases of cervical tear were described. The cerclage was sent to bacteriology after removal, showing positive cultures for Candida species in nine cases (31%). Conclusions: In our study population, late cervical cerclage was found to be a safe procedure resulting in almost 90% of successful vaginal deliveries without maternal or fetal complications. This procedure might be effective in the prolongation of pregnancy in women with cervical dynamics in the late second trimester.

Does gender of the fetus have any relation with fetal heart monitoring during the first and second stage of labor?

OBJECTIVE: To investigate fetal gender and its influences on neonatal outcomes, taking into consideration the available tools for the assessment of fetal well-being. METHODS: We conducted a retrospective study comparing maternal, fetal and neonatal outcomes according to fetal gender, in women carrying a singleton gestation. A multivariate analysis was performed for the prediction of adverse neonatal outcomes according to fetal gender, after adjustment for gestational age, maternal age and fetal weight. RESULTS: A total of 682 pregnancies were included in the study, of them 56% (n = 383) were carrying a male fetus and 44% (n = 299) a females fetus. Male gender was associated with a significant higher rate of abnormal fetal heart tracing patterns during the first (67.7% versus 55.1, p = 0.001) and the second stage (77.6 versus 67.7, p = 0.01) of labor. Male gender was also significantly associated with lower Apgar scores at 1' (19.1% versus 10.7%, p < 0.01), as well as lower pH values (7.18 ± 0.15 versus 7.23 ± 0.18, p < 0.001), and significant differences in cord blood components (PCO2, PO2) compared with female fetuses. In the multivariate analysis, male gender was found to be significantly associated with first (OR 1.76, 95% CI 1.28-2.43, p = 0.001) and second stage (OR 1.73, 95% CI 1.20-2.50, p < 0.01) pathological fetal heart tracing patterns, pH < 7.1, and for Apgar scores at 1'< 7. CONCLUSIONS: The present study confirms the general trend of a lower clinical performance of male neonates compared with females. In addition, the relation between fetal heart rate patterns during all stages of labor and fetal gender showed an independent association between male fetal gender and abnormal fetal heart monitoring during labor.

[Stress and distress in infertility among women].

In the industrialized world, approximately 12% of couples suffer from infertility. As a result of its collective political and historical experience, Israel boasts one of the world's most progressive fertility policies ranging from hormonal treatment to In Vitro Fertilization (IVF). Approximately 40% of the causes of infertility are attributed to the woman. Among the factors contributing to reduced fertility are endocrine factors, immune factors and mechanical factors. Studies have accumulated information regarding the contribution of psychological factors to infertility in women. Among the identified risk factors are depression, anxiety and stress-dependent changes like altered heart rate and increased blood cortisol levels. The hypothalamic-pituitary-adrenal axis (HPA) has been shown to be an important mediator of infertility, involved in the excretion of CRH, ACTH and cortisol, respectively. Data gathered in the literature suggests the involvement of the HPA axis on the hypothalamic-pituitary-gonadotropic axis (HPG). Specifically, changes in diurnal excretion patterns of cortisol have been shown to accompany mental stress and to mediate the down-regulation of the HPG axis. This impact could possibly involve inhibitory mechanisms at the pituitary level, by reducing the release of FSH and LH by GnRH. Furthermore, research has shown that the effect of cortisol on the HPG axis is dependent on the endocrine status of the ovary in its different stages within the menstrual cycle. From the studies presented in this review it can be hypothesized that stress can induce altered cortisol-excretion patterns along the menstrual cycle, which ultimately affect the hormonal profile in critical stages of the fertilization process.

Mitogen-activated protein kinases, inhibitory-kappaB kinase, and insulin signaling in human omental versus subcutaneous adipose tissue in obesity.

MAPKs and inhibitory-kappaB kinase (IKK) were suggested to link various conditions thought to develop in adipose tissue in obesity (oxidative, endoplasmic reticulum stress, inflammation) with insulin resistance. Yet whether in obesity these kinases are affected in a fat-depot-differential manner is unknown. We assessed the expression and phosphorylation of these kinases in paired omental and abdominal-sc fat biopsies from 48 severely obese women (body mass index > 32 kg/m(2)). Protein and mRNAs of p38MAPK, ERK, c-Jun kinase-1, and IKKbeta were increased 1.5-2.5-fold in omental vs. sc fat. The phosphorylated (activated) forms of these kinases were also increased to similar magnitudes as the total expression. However, phosphorylation of insulin receptor substrate-1 on Ser312 (equivalent of murine Ser307) was not increased in omental, compared with sc, fat. Consistently, fat tissue fragments stimulated with insulin demonstrated that tyrosine phosphorylation and signal transduction to Akt/protein kinase B in omental fat was not inferior to that observable in sc fat. Comparison with lean women (body mass index 23.2 +/- 2.9 kg/m(2)) revealed similar ERK2 and IKKbeta expression and phosphorylation in both fat depots. However, as compared with lean controls, obese women exhibited 480 and 270% higher amount of the phosphorylated forms of p38MAPK and c-Jun kinase, respectively, in omental, but not sc, fat, and this expression level correlated with clinical parameters of glycemia and insulin sensitivity. Increased expression of stress-activated kinases and IKK and their phosphorylated forms in omental fat occurs in obesity, potentially contributing to differential roles of omental and sc fat in the pathophysiology of obesity.
