Randomized Trial of Fetal Surgery for Severe Left Diaphragmatic Hernia.

BACKGROUND: Observational studies have shown that fetoscopic endoluminal tracheal occlusion (FETO) has been associated with increased survival among infants with severe pulmonary hypoplasia due to isolated congenital diaphragmatic hernia on the left side, but data from randomized trials are lacking. METHODS: In this open-label trial conducted at centers with experience in FETO and other types of prenatal surgery, we randomly assigned, in a 1:1 ratio, women carrying singleton fetuses with severe isolated congenital diaphragmatic hernia on the left side to FETO at 27 to 29 weeks of gestation or expectant care. Both treatments were followed by standardized postnatal care. The primary outcome was infant survival to discharge from the neonatal intensive care unit. We used a group-sequential design with five prespecified interim analyses for superiority, with a maximum sample size of 116 women. RESULTS: The trial was stopped early for efficacy after the third interim analysis. In an intention-to-treat analysis that included 80 women, 40% of infants (16 of 40) in the FETO group survived to discharge, as compared with 15% (6 of 40) in the expectant care group (relative risk, 2.67; 95% confidence interval [CI], 1.22 to 6.11; two-sided P = 0.009). Survival to 6 months of age was identical to the survival to discharge (relative risk, 2.67; 95% CI, 1.22 to 6.11). The incidence of preterm, prelabor rupture of membranes was higher among women in the FETO group than among those in the expectant care group (47% vs. 11%; relative risk, 4.51; 95% CI, 1.83 to 11.9), as was the incidence of preterm birth (75% vs. 29%; relative risk, 2.59; 95% CI, 1.59 to 4.52). One neonatal death occurred after emergency delivery for placental laceration from fetoscopic balloon removal, and one neonatal death occurred because of failed balloon removal. In an analysis that included 11 additional participants with data that were available after the trial was stopped, survival to discharge was 36% among infants in the FETO group and 14% among those in the expectant care group (relative risk, 2.65; 95% CI, 1.21 to 6.09). CONCLUSIONS: In fetuses with isolated severe congenital diaphragmatic hernia on the left side, FETO performed at 27 to 29 weeks of gestation resulted in a significant benefit over expectant care with respect to survival to discharge, and this benefit was sustained to 6 months of age. FETO increased the risks of preterm, prelabor rupture of membranes and preterm birth. (Funded by the European Commission and others; TOTAL ClinicalTrials.gov number, NCT01240057.).

Randomized Trial of Fetal Surgery for Moderate Left Diaphragmatic Hernia.

BACKGROUND: Fetoscopic endoluminal tracheal occlusion (FETO) has been associated with increased postnatal survival among infants with severe pulmonary hypoplasia due to isolated congenital diaphragmatic hernia on the left side, but data are lacking to inform its effects in infants with moderate disease. METHODS: In this open-label trial conducted at many centers with experience in FETO and other types of prenatal surgery, we randomly assigned, in a 1:1 ratio, women carrying singleton fetuses with a moderate isolated congenital diaphragmatic hernia on the left side to FETO at 30 to 32 weeks of gestation or expectant care. Both treatments were followed by standardized postnatal care. The primary outcomes were infant survival to discharge from a neonatal intensive care unit (NICU) and survival without oxygen supplementation at 6 months of age. RESULTS: In an intention-to-treat analysis involving 196 women, 62 of 98 infants in the FETO group (63%) and 49 of 98 infants in the expectant care group (50%) survived to discharge (relative risk , 1.27; 95% confidence interval [CI], 0.99 to 1.63; two-sided P = 0.06). At 6 months of age, 53 of 98 infants (54%) in the FETO group and 43 of 98 infants (44%) in the expectant care group were alive without oxygen supplementation (relative risk, 1.23; 95% CI, 0.93 to 1.65). The incidence of preterm, prelabor rupture of membranes was higher among women in the FETO group than among those in the expectant care group (44% vs. 12%; relative risk, 3.79; 95% CI, 2.13 to 6.91), as was the incidence of preterm birth (64% vs. 22%, respectively; relative risk, 2.86; 95% CI, 1.94 to 4.34), but FETO was not associated with any other serious maternal complications. There were two spontaneous fetal deaths (one in each group) without obvious cause and one neonatal death that was associated with balloon removal. CONCLUSIONS: This trial involving fetuses with moderate congenital diaphragmatic hernia on the left side did not show a significant benefit of FETO performed at 30 to 32 weeks of gestation over expectant care with respect to survival to discharge or the need for oxygen supplementation at 6 months. FETO increased the risks of preterm, prelabor rupture of membranes and preterm birth. (Funded by the European Commission and others; TOTAL ClinicalTrials.gov number, NCT00763737.).

Autoantibody screening of plasma and peritoneal fluid of patients with endometriosis.

STUDY QUESTION: Are there specific autoantibody profiles in patients with endometriosis that are different from those in controls? SUMMARY ANSWER: This study did not reveal a significantly higher prevalence of autoantibodies in the studied groups of patients. WHAT IS KNOWN ALREADY: Various inflammatory factors are postulated to be involved in the pathomechanisms of endometriosis, and a potential link exists with autoimmune diseases, which may also play an important role. As the diagnosis of endometriosis remains invasive, it can only be confirmed using laparoscopy with histopathological examination of tissues. Numerous studies have focused on identifying useful biomarkers to confirm the disease, but without unequivocal effects. Autoantibodies are promising molecules that serve as potential prognostic factors. STUDY DESIGN, SIZE, DURATION: A multicentre, cross-sectional study was conducted over 18 months (between 2018 and 2019), at eight Departments of Obstetrics and Gynaecology in several cities across Poland on 137 patients undergoing laparoscopic examination for the diagnosis of endometriosis. PARTICIPANTS/MATERIALS, SETTINGS, METHODS: During laparoscopy, we obtained plasma samples from 137 patients and peritoneal fluid (PF) samples from 98 patients. Patients with autoimmune diseases were excluded from the study. Autoantibody profiling was performed using HuProt v3.1 human proteome microarrays. MAIN RESULTS AND THE ROLE OF CHANCE: We observed no significant differences in the expression of autoantibodies in the plasma or PF between the endometriosis and control groups. The study revealed that in the PF of women with Stage II endometriosis, compared with other stages, there were significantly higher reactivity signals for ANAPC15 and GABPB1 (adj. P < 0.016 and adj. P < 0.026, respectively; logFC > 1 in both cases). Comparison of the luteal and follicular phases in endometriosis patients revealed that levels of NEIL1 (adj. P < 0.029), MAGEB4 (adj. P < 0.029), and TNIP2 (adj. P < 0.042) autoantibody signals were significantly higher in the luteal phase than in the follicular phase in PF samples of patients with endometriosis. No differences were observed between the two phases of the cycle in plasma or between women with endometriosis and controls. Clustering of PF and plasma samples did not reveal unique autoantibody profiles for endometriosis; however, comparison of PF and plasma in the same patient showed a high degree of concordance. LIMITATIONS, REASONS FOR CAUTION: Although this study was performed using the highest-throughput protein array available, it does not cover the entire human proteome and cannot be used to study potentially promising post-translational modifications. Autoantibody levels depend on numerous factors, such as infections; therefore the autoantibody tests should be repeated for more objective results. WIDER IMPLICATIONS OF THE FINDINGS: Although endometriosis has been linked to different autoimmune diseases, it is unlikely that autoimmune responses mediated by specific autoantibodies play a pivotal role in the pathogenesis of this inflammatory disease. Our study shows that in searching for biomarkers of endometriosis, it may be more efficient to use higher-throughput proteomic microarrays, which may allow the detection of potentially new biomarkers. Only research on such a scale, and possibly with different technologies, can help discover biomarkers that will change the method of endometriosis diagnosis.

The Influence of Lactoferrin in Plasma and Peritoneal Fluid on Iron Metabolism in Women with Endometriosis.

The aim of this study was to investigate the relationship between lactoferrin and iron and its binding proteins in women with endometriosis by simultaneously measuring these parameters in plasma and peritoneal fluid. Ninety women were evaluated, of whom 57 were confirmed as having endometriosis. Lactoferrin was measured by ELISA, transferrin, ferritin and iron on a Cobas 8000 analyser. Lactoferrin and transferrin in peritoneal fluid were lower compared to plasma, in contrast to ferritin and iron. In plasma, lactoferrin showeds associations with iron and transferrin in endometriosis and with ferritin in the group without endometriosis. Lactoferrin in peritoneal fluid correlated with lactoferrin, iron and transferrin of plasma in patients without endometriosis. The ratio of lactoferrin concentration in peritoneal fluid to plasma differentiated stage I versus IV of endometriosis and was negatively correlated with the iron ratio in patients without endometriosis. The ferritin ratio differentiated women with and without endometriosis. The very high ferritin ratios, especially in advanced stages of endometriosis, suggest the protective involvement of this protein in peritoneal fluid and the loss of this role by lactoferrin. The results demonstrate the validity of assessing iron metabolism in women with endometriosis, which may be useful as a marker of the disease and its progression.

Investigation of the Changes in Concentrations of Vitamin D-Binding Protein and Lactoferin in Plasma and Peritoneal Fluid of Patients with Endometriosis.

An evaluation of the association between the concentrations of vitamin D-binding protein and lactoferrin in the plasma and peritoneal fluid may facilitate the elucidation of molecular mechanisms in endometriosis. Vitamin D-binding protein and lactoferrin concentrations were measured by ELISA in plasma and peritoneal fluid samples from 95 women with suspected endometriosis as classified by laparoscopy into groups with (n = 59) and without endometriosis (n = 36). There were no differences (p > 0.05) in the plasma and peritoneal fluid concentrations of vitamin D-binding protein and lactoferrin between women with and without endometriosis. In women with endometriosis, there was a significant correlation between plasma and peritoneal fluid vitamin D-binding protein concentrations (r = 0.821; p = 0.000), but there was no correlation between lactoferrin concentrations in those compartments (r = 0.049; p > 0.05). Furthermore, in endometriosis, lactoferrin was found to correlate poorly with vitamin D-binding protein (r= -0.236; p > 0.05) in plasma, while in the peritoneal fluid, the correlation between those proteins was significant (r = 0.399; p = 0.002). The characteristic properties of vitamin D-binding protein and lactoferrin and the associations between their plasma and peritoneal fluid concentrations found in women with endometriosis may provide a novel panel of markers to identify high-risk patients in need of further diagnostic measures.

Evaluation of Proteasome and Immunoproteasome Levels in Plasma and Peritoneal Fluid in Patients with Endometriosis.

Endometriosis is a chronic disease in which the endometrium cells are located outside the uterine cavity. The aim of this study was to evaluate circulating 20S proteasome and 20S immunoproteasome levels in plasma and peritoneal fluid in women with and without endometriosis in order to assess their usefulness as biomarkers of disease. Concentrations were measured using surface plasmon resonance imaging biosensors. Patients with suspected endometriosis were included in the study-plasma was collected in 112 cases and peritoneal fluid in 75. Based on the presence of endometriosis lesions detected during laparoscopy, patients were divided into a study group (confirmed endometriosis) and a control group (patients without endometriosis). Proteasome and immunoproteasome levels in both the plasma (p = 0.174; p = 0.696, respectively) and the peritoneal fluid (p = 0.909; p = 0.284, respectively) did not differ between those groups. There was a statistically significant difference in the plasma proteasome levels between patients in the control group and those with mild (Stage I and II) endometriosis (p = 0.047) and in the plasma immunoproteasome levels in patients with ovarian cysts compared to those without (p = 0.017). The results of our study do not support the relevance of proteasome and immunoproteasome determination as biomarkers of the disease but suggest a potentially active role in the pathogenesis of endometriosis.

Twin-to-twin transfusion syndrome complicated with in utero limb ischemia of the donor twin - a case report.

BACKGROUND: In utero limb ischemia is a rare complication of the monochorionic twin pregnancies complicated with twin to twin transfusion syndrome (TTTS). The condition is more often seen in recipient twins. There are few theories of the pathogenesis including in utero venous thromboembolism, but the cause remains unclear. However, limb ischemia is thought to be unrelated with any prenatal intervention. CASE PRESENTATION: We present a case of a monochorionic twin pregnancy complicated with TTTS admitted to the Clinic for selective fetoscopic laser photocoagulation. The invasive procedure failed due to poor visibility. In the following weeks of pregnancy, amnioreduction procedures were performed. At 28 weeks of gestation due to twin anemia-polycythemia sequence diagnosis the patient was qualified for cesarean section. Postnatally, the donor twin was diagnosed with lower right limb ischemic necrosis. The extremity was amputated 2 days later with an uncomplicated recovery. After speculations of the potential pathogeneses it was suggested that the ischemic limb occurred as a complication of the main condition - TTTS. CONCLUSIONS: In literature, there have been no cases reported of TTTS stage I complicated with donor twin limb ischemia. The actual cause of the in utero limb ischemic necrosis in monochorionic twins remains unknown. Nevertheless, increased attention to the potential complication after failed invasive procedures or conservative treatment should be required.

Plasma and Peritoneal Fluid Fibronectin and Collagen IV Levels as Potential Biomarkers of Endometriosis.

Laparoscopy as a diagnostic tool for patients with suspected endometriosis is associated with several potentially life-threatening complications. Therefore, it is imperative to identify reliable, non-invasive biomarkers of the disease. The aim of this study was to analyse the concentrations of fibronectin and type IV collagen in peritoneal fluid and plasma to assess their role as potential biomarkers in the diagnosis of endometriosis. Fibronectin and collagen IV protein levels were assessed by surface plasmon resonance imaging (SPRi) biosensors with the usage of monoclonal antibodies. All patients enrolled in the study were referred for laparoscopy for the diagnosis of infertility or chronic pelvic pain (n = 84). The study group included patients with endometriosis confirmed during surgery (n = 49). The concentration of fibronectin in the plasma (329.3 ± 98.5 mg/L) and peritoneal fluid (26.8 ± 11.1 µg/L) in women with endometriosis was significantly higher than in the control group (251.2 ± 84.0 mg/L, 7.0 ± 5.9 µg/L). Fibronectin levels were independent of endometriosis stage (p = 0.874, p = 0.469). No significant differences were observed in collagen IV levels (p = 0.385, p = 0.465). The presence of elevated levels of fibronectin may indicate abnormalities in cell-ECM signalling during the course of endometriosis, and may be a potential biomarker for early detection.

Longitudinal changes in maternal left atrial volume index and uterine artery pulsatility indices in uncomplicated pregnancy.

BACKGROUND: Data on the relationship between longitudinal changes in maternal volume-dependent echocardiographic parameters and placentation in uncomplicated pregnancy are limited. OBJECTIVE: This study aimed to evaluate changes in volume-dependent echocardiographic parameters in uncomplicated pregnancy to test the hypothesis of the existence of an association between volume-dependent echocardiographic parameters and Doppler ultrasound parameters of fetal circulation and the uterine artery in uncomplicated pregnancy and to establish which of the volume-dependent echocardiographic parameters best depicts volume changes and correlates best with Doppler ultrasound of fetal circulation and the uterine artery in healthy pregnancy. STUDY DESIGN: Data from 60 healthy pregnant women were analyzed. A complete echocardiographic study was performed at 11 to 13, 20 to 22, and 30 to 32 weeks' gestation: left ventricular end-diastolic volume, early diastolic peak flow velocity, late diastolic peak flow velocity, left atrial area, and left atrial volume index were assessed. Obstetrical assessment was performed including fetal growth and uterine artery pulsatility index. Fetal well-being was assessed by umbilical and middle cerebral artery blood flow. Serum pregnancy-associated plasma protein A and free ß-human chorionic gonadotropin were assessed during the routine first-trimester scan (11-13 weeks' gestation). RESULTS: Left ventricular end-diastolic volume and left atrial area increased significantly between 11 to 13 and 20 to 22 weeks' gestation but not between 20 to 22 and 30 to 32 weeks' gestation. Left atrial volume index measured at 30 to 32 weeks' gestation correlated with uterine artery pulsatility indices in 3 trimesters. Changes in the left atrial volume index between the third and first trimesters correlated significantly with the uterine artery pulsatility index measured at 20 to 22 weeks' gestation (r=-0.345; P=.020) and at 30 to 32 weeks' gestation (r=-0.452; P=.002). Changes in the left atrial volume index between the second and first trimesters significantly correlated with the uterine artery pulsatility index measured in the first trimester (r=-0.316; P=.025). CONCLUSION: Our study showed that in an uncomplicated pregnancy, among volume-dependent echocardiographic parameters, left atrial volume index increased between both the first and second trimesters and the second and third trimesters and correlated with parameters of Doppler ultrasound of the fetal circulation and the uterine artery. Our results expand on the previous observation on the relationship between maternal cardiovascular adaptation and placentation in women with heart diseases to the population of healthy women with uncomplicated pregnancy.

Impact of childbirth on women's sexuality in the first year after the delivery.

AIM: The aim was to compare the quality of sexual life before pregnancy and after delivery and to find out whether and how selected factors affect women's sexuality during this period. METHODS: The study group consisted of 433 women who completed the survey containing basic demographic questions and two Female Sexual Function Index (FSFI) questionnaires: a retrospective one, regarding time before pregnancy and the current period. The inclusion criteria: time between 10 weeks and 1 year after delivery, vaginal intercourses before pregnancy and the resumption of vaginal intercourses after delivery. RESULTS: We observed the negative impact of labor on the total FSFI score, regardless of the time that had passed since birth and the delivery mode. The decrease by at least 10% of the initial FSFI score was noticed in 44.3% of the participants. FSD (Female Sexual Dysfunction) occurred statistically more commonly after delivery than before pregnancy (45.3% vs 17.1%; P < 0.001). The following factors had an impact on the risk of post-partum FSD: pre-pregnancy FSD (adjusted odds ratio [aOR] = 4.17 [95% confidence interval [CI] 2.38-7.31]) and nulliparity (aOR = 1.67 [95% CI 1.09-2.53]). CONCLUSION: Childbirth has an undeniable impact on women's sexuality. The prevention and treatment of sexual dysfunctions is very important, especially in this crucial period of life.

How to avoid drug resistance during treatment and prevention of urinary tract infections.

Urinary tract infections (UTIs), defined as the presence of bacteria above the bladder sphincter, are among the most common infectious diseases. They remain a significant cause of antibiotic prescription worldwide. The incidence is much higher among women, especially of reproductive age, than among men. If the infection occurs at least 3 times a year or twice within 6 months, it is classified as recurrent urinary tract infection (rUTI). Among the causal pathogens, the vast majority are Gram-negative bacteria, the most common of which is Escherichia coli. Recommended treatment regimens differ depending on the diagnosed disease entity and the patient's clinical situation. Empirical antibiotic therapy is most often used. The first-line treatment in patients with acute simple cystitis include nitrofurantoin, trimethoprim-sulfamethoxazole, or fosfomycin. Beta-lactams and fluoroquinolones should be considered as a second-line agent. In particular cases (pregnancy or rUTIs) targeted treatment, based on the results of urine culture and antibiogram, is implemented. During pregnancy recommended treatment includes administration of cephalosporins (e.g. cefuroxime) or nitrofurantoin. In patients with uncomplicated pyelonephritis fluoroquinolones should be considered as the first-line regimen. In the case of rUTIs, there are no uniform guidelines for prophylactic management. Repeated administration of antibiotics due to infections leads to a growing problem of drug resistance. Most recommendations suggest not to use antibiotic prophylaxis routinely. Growing evidence favours non-antibiotic prophylaxis regimens for recurrent UTIs. Until now only one product - oral immunostimulant OM-89 - has been sufficiently investigated. Wider implementation of immunoprophylaxis in the future may reduce possible side effects of inappropriate antibiotic consumption.

Vascular anastomoses in intrauterine growth in monochorionic twins.

Objectives To evaluate the impact of placental anastomoses on the intrauterine growth of monochorionic (MC) twins. Methods A prospective study was conducted in a group of 53 MC twins. Intrapartally umbilical cords were clamped to identify placental sides corresponding to each twin. The postnatal dye injection technique was administered to evaluate vascular anastomoses, their number and type and visualize placental territory sharing patterns. Data from digital analysis were correlated with obstetrical follow-up. Results Vascular anastomoses were revealed in 88.7% of cases. Arteriovenous (AV) anastomoses occurred in 75.4% and arterioarterial (AA) in 71.1% while venovenous (VV) in 26.4%. In the subgroup of MC twins without placental anastomoses, significantly higher birthweight difference and discordance were revealed when compared to MC twins without anastomoses (382.0 vs. 22 g; P = 0.03 and 49.14% vs. 16.02%; P = 0.03). On the other hand, in subgroups of MC twins with at least one AA anastomosis, twins' birthweights were similar (p = ns) despite significantly higher placental territory sharing discordance (30.44% vs. 15.81%; P = 0.31). Conclusions Vascular anastomoses have a major impact on the intrauterine growth of MC twins. In certain cases, they may cause specific complications; however, in general, they regulate intertwin blood exchange and may compensate unequal placental territory.

Premature ovarian insufficiency as a variable feature of blepharophimosis, ptosis, and epicanthus inversus syndrome associated with c.223C > T p.(Leu75Phe) FOXL2 mutation: a case report.

BACKGROUND: FOXL2 gene mutations cause blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) and may be associated with premature ovarian insufficiency (POI). Two types of BPES were described in the literature. BPES type 2 is a simple association of inherited developmental defects of the eyelid area, while in type 1 female patients additionally suffer from POI. The following case study is the first report of endocrine impairments typical for menopausal transition in young female with NG_012454.1:g.138665342G > A, c.223C > T p.(Leu75Phe), mutation in FOXL2 gene. This mutation has been reported in the literature before, however until now, it was never linked to BPES type 1. CASE PRESENTATION: An 18-year-old nulliparous woman suspected of secondary amenorrhea was referred to our Endocrinology Outpatient Clinic. Blood tests revealed decreased levels of AMH (anti-Mullerian hormone) and increased levels of gonadotropins, suggesting menopausal transition. Her past medical history was remarkable for several ophthalmic defects that has required surgical interventions. BPES syndrome had not been suspected before, although the patient had reported a similar phenotype occurring in her father, sister and half-sister. Venous blood samples were collected from the female proband and from her three family members. Whole-exome sequencing and deep amplicon sequencing were performed. A potential pathogenic variant in the FOXL2 gene was revealed. Namely, the c.223C > T p.(Leu75Phe) missense variant was detected. CONCLUSIONS: The authors found mutations, c.223C > T p.(Leu75Phe) in the FOXL2 gene in a young woman with hormonal disorders suggesting menopausal transition. These results indicate that the possibility of different phenotypes should be considered in patients with a similar genetic mutation.

Sex education in Poland - a cross-sectional study evaluating over twenty thousand polish women's knowledge of reproductive health issues and contraceptive methods.

BACKGROUND: Reproductive health is a part of a comprehensive definition of complete physical, mental and social well-being. Sex education is an important aspect of public health. Ignorance, due to the lack of sex education leads to risky sexual behaviors. METHODS: Our cross-sectional study was aimed at investigating a representative group of Polish women's knowledge about the physiology of the menstrual cycle, contraceptive methods, infertility and cervical cancer prevention. The data were collected by face-to-face interviews and an anonymous electronic questionnaire. RESULTS: The study group involved 20,002 respondents. Most of the women were of reproductive age (mean 27.7), parous (60.8%), of higher education (71%) and living in large cities (> 500 k citizens, 36.8%). 62.2% of the women gave correct answers to at least 5 of 7 questions concerning the physiology of the menstrual cycle. Three factors had a significant influence on the number of correct answers: higher education (p = 0.0001), more frequent gynecological appointments (p = 0.0001) and living in a larger city (p = 0.002). Women of higher education level had more often used some form of contraceptive method previously (87% vs. 78.4%, p = 0.001), recommended natural family planning methods to their peers (18.4% vs. 15%, p = 0.001) and regularly attended gynecological appointments (85.7% vs. 78.8%, p = 0.001) when compared with those women with lower educational levels. The three most effective contraceptive methods identified by respondents were: oral contraceptives (71.1% answers), intrauterine devices (50.2%) and parenteral hormonal contraceptives (30.4%). The effectiveness of natural family planning was more often emphasized by women who had never used any contraceptives before (20.1% vs 6.7%). Most of the participants (80.8%) believed that in-vitro fertilization is an effective infertility treatment and should be reimbursed in Poland. Also, 95.2% of the respondents reported that they had undergone a Papanicolaou test within the past 3 years, but only 3% of these women were aware of all the risk factors for cervical cancer mentioned in our survey. CONCLUSIONS: It is very important to improve comprehensive reproductive health education in Poland, especially among women of lower educational levels and living in small centers. In future, educational programs and gynecologists should focus on implementing and improving these aforementioned issues.

Maternal Nutritional and Water Homeostasis as a Presage of Fetal Birth Weight.

Birth weight is a key determinant of perinatal outcomes which affect physical development and metabolic function. In this study, we evaluated the potential role of maternal body composition and nutritional status in programing fetal birth weight. This was a longitudinal study that included 29 pregnant women and their full-term newborns. Maternal dietary energy and fluid intake and body adipose tissue were assessed. In addition, we measured the serum content of copeptin, aldosterone, and angiotensin II in maternal and umbilical cord blood. The measurements were done across the three trimesters of pregnancy, on average, at 11.6 weeks, 18.3 weeks, and 30.2 weeks. Each newborn's birth weight was determined at the percentile line, using the World Health Organization (WHO) standards based on the gestational age, gender, and weight. We found no appreciable relation of fetal birth weight to the maternal dietary and fluid intakes, and the content of angiotensin II, aldosterone, or copeptin. However, birth weight correlated with increases in body adipose tissue in early pregnancy stages. Further, birth weight correlated positively with copeptin and adversely with angiotensin II in cord blood. We conclude that the present findings may be helpful in the assessment of a critical level of body adipose tissue in women of child-bearing age, above which the potential risk of macrosomia appears. The female population of child-bearing age needs a continual update on the nutritional knowledge to prevent modifiable maternal and fetal perinatal complications.

The use of atosiban prolongs pregnancy in patients treated with fetoscopic endotracheal occlusion (FETO).

Objective To evaluate the impact of atosiban as a tocolytic agent in patients treated with the fetoscopic endotracheal occlusion (FETO) procedure due to congenital diaphragmatic hernia (CDH). As premature birth after fetoscopy remains a serious concern, an effort to reduce prematurity is required. Methods A total of 43 patients with severe CDH treated with FETO were enrolled in this study. The study group consisted of 22 patients who received atosiban during the FETO procedure and a control group of 21 patients who did not receive atosiban during the FETO procedure. Demographic data, gestational age (GA) at delivery, cervical length and GA at premature rupture of membranes (PROM) were evaluated. Results The GA at delivery was significantly different between the two groups studied. The median GA at delivery was 32.6 and 34.5 weeks in the no-atosiban vs. atosiban groups, respectively (P = 0.013). The median cervical length was 29.9 and 31.2 mm for the no-atosiban and atosiban groups, respectively, and was not statistically significant (P = 0.28). There were no significant correlations between groups for the occurrence of PROM, GA at the time of PROM, duration of the procedures, parity, maternal body mass index (BMI) or age. In the univariate linear regression model, the only factor independently associated with GA at delivery was the use of atosiban during FETO procedures (ß = 0.375; P < 0.013). Conclusion In cases of severe CDH treated with FETO, the use of atosiban as a tocolytic agent during the procedure prolonged pregnancy by 2 weeks. Cervical length, duration of FETO or maternal characteristics were not associated with GA at delivery.

Pipelle biopsy and dilatation and curettage in clinical practice: are factors affecting their effectiveness the same?

AIM: Endometrial biopsy is one of the most commonly performed gynecological procedures. Apart from patient safety, the most important is to obtain an adequate specimen allowing histopathological diagnosis. The aim of the study was to determine the rate of endometrial sampling failure and factors affecting the quality of specimen obtained for histopathological examination among patients who underwent Pipelle biopsy and dilatation and curettage (D&C). METHODS: Patients who underwent endometrial biopsy (Pipelle, D&C) at the 1st Department of Obstetrics and Gynecology, Medical University of Warsaw, between June 2013 and July 2017, were included in the study. The influence of menopausal status, body mass index, obstetric history, endometrial thickness, indications for the biopsy and doctors' experience were analyzed with regard to the effectiveness of the procedure. RESULTS: Overall, 895 endometrial sampling procedures were performed. Three hundred and thirty-nine (37.9%) patients underwent Pipelle biopsy, while 556 (62.1%) had D&C. Insufficient samples were found in 60 (17.3%) and 88 (15.8%) patients, respectively. Age, menopausal status and indications were factors affecting both procedures, while the number of previous vaginal deliveries, body mass index and endometrial thickness influenced the effectiveness of Pipelle biopsy. Doctors' experience did not influence the specimen adequacy. CONCLUSION: None of the methods guarantee obtaining adequate specimens. D&C might be preferred in postmenopausal women. The effectiveness of both procedures is independent of doctors' experience.

Uterine torsion in the second trimester of pregnancy.

OBJECTIVES: Torsion of the pregnant uterus is a very rare complication. It may occur at any gestational age. The treatment depends on the intensity of symptoms, intraoperative ischemic signs and the gestational age. MATERIAL AND METHODS: We present a case report of 33-year-old primipara accidentally diagnosed with uterine torsion during appedectomy. CASE DESCRIPTION: The patient underwent surgery at 19th week of gestation due to severe pain in the right iliac fossa and increased levels of inflammation markers. Intraoperatively acute appendicitis and levorotation of the uterus by about 100 degrees were found. As the signs of ischemia were absent, the uterus was returned into its normal position. Intraoperative and postoperative period was uncomplicated. Close outpatient monitoring was introduced and the pregnancy continued without further complications. The patient underwent cesarean section at 36 weeks of pregnancy due to early leakage of amniotic fluid and failure to progress during first stage of labor. CONCLUSIONS: Uterine torsion may present with non-specific symptoms or be asymptomatic. Urgent laparotomy and rotation of the uterus into its normal anatomical position gives chance for normal course of pregnancy. Subsequent close outpatient care is obligatory to asses viability of the fetus and early detection of possible pregnancy complications.

Cervical Measurement and Pessary Application in Relation to Gestational Age at Delivery in Patients Treated with Fetoscopic Endotracheal Occlusion.

OBJECTIVE: To evaluate the impact of cervical length and cervical pessary application in congenital diaphragmatic hernia (CDH) treated by the fetoscopic endotracheal occlusion (FETO) procedure. METHODS: The study group consisted of 80 patients with severe CDH treated by FETO. Cervical length measurement was performed by transvaginal ultrasound in all patients within the 24 h prior to the FETO procedure. The study group (n = 44) had cervical pessaries applied routinely within the 24 h following the FETO procedure, whereas the control group (n = 36) were not offered pessaries and only had cervical length measurement performed. RESULTS: The median cervical length was 31 (range 22-45) mm. The median gestational age at delivery was 34.7 (range 27.8-39.2) weeks. Gestational age at delivery correlated significantly with gestational age at balloon removal (r = 0.768; p < 0.0001) and premature rupture of membranes (r = 0.501; p = 0.003). There was no significant correlation between gestational age at delivery and cervical length before the procedure (r = 0.141; p = 0.26) or pessary application (r = 0.081; p = 0.51). In the multivariate linear regression model, the only factor independently associated with gestational age at delivery was gestational age at fetoscopic balloon removal (ß = 0.713; p < 0.0001). CONCLUSION: In cases of severe CDH treated by the FETO procedure, neither cervical length before the procedure nor cervical pessary application was associated with gestational age at delivery.

Is there a future for cell-free fetal dna tests in screening for preeclampsia?

CffDNA screening is a powerful diagnostic tool in the prenatal diagnosis algorithm for chromosomal abnormalities. With detailed ultrasound examination as the mainstay of first-trimester risk assessment, cffDNA has been shown to be superior to first-trimester combined screening (FTCS) in false-positive rates for trisomy 21 detection. In light of the growing interest in cffDNA testing and the possibility of it replacing first-trimester biochemistry, we decided to investigate the usefulness of cffDNA tests in early-pregnancy risk assessment for preeclampsia (PE). The aim of this review paper was to evaluate clinical application of first-trimester cfDNA in predicting PE, as well as to investigate its possible use in first-trimester PE screening enhancement, also in cases where biochemistry is not performed.
