<p><strong>Objective:</strong> The aim of this study is to compare the perinatal outcomes of double cerclage via laparoscopic plus transvaginal technique in women with a history of transvaginal cerclage failure, between women with single transvaginal cerclage.</p><p><strong>Study Design:</strong> Five women who were diagnosed with cervical insufficiency with a history of at least one vaginal cerclage failure and 10 women who were diagnosed with cervical insufficiency were included in this study. Laparoscopic cerclage was performed to all women who have a medical history of vaginal cerclage failure, before pregnancy and additional transvaginal cervical cerclage was performed during their pregnancy (Group 1). Single transvaginal cervical cerclage was performed to the 10 women who had a short cervix and/or cervical insufficiency during their pregnancy (Group 2). The number of cerclage failure, perinatal outcomes, gestational week at the time of delivery, birth weight and Apgar scores were evaluated.</p><p><strong>Results:</strong> All five women in group 1 underwent a cesarean section. None of them had chorioamnionitis or poor obstetric outcomes and all gave birth after the 34th week of pregnancy. All ten women in group 2 were evaluated. Two women gave birth vaginally at the 33rd week of pregnancy. Remaining eight cases gave birth above 34th week of pregnancy. Six of the eight cases underwent cesarean section and two of the remaining were delivered vaginally. Mean birth weight of the fetuses were 2490±265 g and 2.710 ±361 g in group1 and group 2, respectively. Mean gestational age at the time of birth in group 1 and group 2 were found 36±1.83 weeks and 35.6±1.14 weeks, respectively.</p><p><strong>Conclusion:</strong> Laparoscopic cervical cerclage during pregnancy could be a safe and effective treatment. However, sometimes it might not be enough and transvaginal cervical cerclage may be needed to strengthen cervical tension.</p>

Introduction. The formation of isthmic-cervical insufficiency (ICI) in 80% is associated with intraamnial inflammation, this is the subject of discussion of new mechanisms of the pathogenesis of premature cervical remodeling. In this regard, it is of interest to study the relationship of ICS with intrauterine and cervicovaginal infections during pregnancy and their impact on the course and outcomes of pregnancy, which was the purpose of our study.Methods. A prospective cohort study included 100 pregnant women with ICI, taken by a continuous sample. All patients at the time of ICI manifestation underwent a comprehensive clinical and laboratory examination aimed at diagnosing cervicovaginal infections, according to e results of which the pregnant women were divided into 2 groups: the first group consisted of 72 women with ICI and cervicovaginal infections, the second group — 28 women with ICI and normocenosis of the vagina.Results. There were no significant differences between the compared groups in terms of the history of miscarriage, extragenital pathology and the frequency of complications of this pregnancy. Intrauterine infection during pregnancy in patients of group 1 was observed 4 times more often, being 55.6% (40) versus 14.3% (4) in group 2 (RR = 3.9, 95% CI = 1.5-9.9, p <0.001). Preterm birth was significantly more frequent in women of group 1, accounting for 62.5% (45), in group 2 — 28.6% (8). Perinatal mortality cases were observed only in group 1, amounting to 97‰ (7). In children from women in group 1, complications of the early neonatal period were more common, primarily due to prematurity. In addition, IUI in newborns was diagnosed 10 times more often in group 1, reaching 38.8% (26) of cases, compared with group 2 — 3.6% (1) (RR = 10.87, 95% CI = 1.55–76.22, p <0.001).Discussion. Perinatal outcomes in ICI associated with cervicovaginal infections are characterized by the presence of perinatal mortality, a higher incidence of preterm birth and IUI of the newborn than in women with ICI without cervicovaginal infection.

BackgroundLow birth weight, prematurity and higher miscarriage rates have previously been reported in women with eating disorders.AimsTo determine whether women with a history of eating disorders are at higher risk of major adverse perinatal outcomes.MethodsAdjusted birth weight, preterm delivery and miscarriage history were compared in those with a history of eating disorders (anorexia nervosa (n=171), bulimia nervosa (n=199) and both (n=82)) and those with other (n=1166) and no psychiatric disorders (n=10 636) in a longitudinal cohort study.ResultsThe group with bulimia nervosa had significantly higher rates of past miscarriages (relative risk ratio 2.0, P=0.01) and the group with anorexia nervosa delivered babies of significantly lower birth weight than the general population (P=0.01), which was mainly explained by lower pre-pregnancy body mass index. Preterm delivery rates were comparable across groups.ConclusionsWomen with a history of eating disorders are at higher risk of major adverse obstetric outcomes. Antenatal services should be aware of this higher risk.

AbstractOestradiol, an important hormone in follicular development and endometrial receptivity, is closely related to clinical outcomes of fresh in vitro fertilization-embryo transfer (IVF-ET) cycles. A supraphysiologic E2 level is inevitable during controlled ovarian hyper-stimulation (COH), and its effect on the outcome of IVF-ET is controversial. The aim of this retrospective study is to evaluate the association between elevated serum oestradiol (E2) levels on the day of human chorionic gonadotrophin (hCG) administration and neonatal birthweight after IVF-ET cycles. The data of 3659 infertile patients with fresh IVF-ET cycles were analysed retrospectively between August 2009 and February 2017 in First Hospital of Zhengzhou University. Patients were categorized by serum E2 levels on the day of hCG administration into six groups: group 1 (serum E2 levels ≤ 1000 pg/mL, n = 230), group 2 (serum E2 levels between 1001 and 2000 pg/mL, n = 524), group 3 (serum E2 levels between 2001 and 3000 pg/mL, n = 783), group 4 (serum E2 levels between 3001 and 4000 pg/mL, n = 721), group 5 (serum E2 levels between 4001 and 5000 pg/mL, n = 548 ), and group 6 (serum E2 levels > 5000 pg/mL, n = 852). Univariate linear regression was used to evaluate the independent correlation between each factor and outcome index. Multiple logistic regression was used to adjust for confounding factors. The LBW rates were as follows: 3.0% (group 1), 2.9% (group 2), 1.9% (group 3), 2.9% (group 4), 2.9% (group 5), and 2.0% (group 6) (P = 0.629), respectively. There were no statistically significant differences in the incidences of neonatal LBW among the six groups. We did not detect an association between peak serum E2 level during ovarian stimulation and neonatal birthweight after IVF-ET. The results of this retrospective cohort study showed that serum E2 peak levels during ovarian stimulation were not associated with birth weight during IVF cycles. In addition, no association was found between higher E2 levels and increased LBW risk. Our observations suggest that the hyper-oestrogenic milieu during COS does not seem to have adverse effects on the birthweight of offspring after IVF. Although this study provides some reference, the obstetric-related factors were not included due to historical reasons. The impact of the high estrogen environment during COS on the birth weight of IVF offspring still needs future research.

AimsMyeloid neoplasms occur in the setting of chronic lymphocytic leukaemia (CLL)/CLL-like disease. The underlying pathogenesis has not been elucidated.MethodsRetrospectively analysed 66 cases of myeloid neoplasms in patients with CLL/CLL-like disease.ResultsOf these, 33 patients (group 1) had received treatment for CLL/CLL-like disease, while the other 33 patients (group 2) had either concurrent diagnoses or untreated CLL/CLL-like disease before identifying myeloid neoplasms. The two categories had distinct features in clinical presentation, spectrum of myeloid neoplasm, morphology, cytogenetic profile and clinical outcome. Compared with group 2, group 1 demonstrated a younger age at the diagnosis of myeloid neoplasm (median, 65 vs 71 years), a higher fraction of myelodysplastic syndrome (64% vs 36%; OR: 3.1; p<0.05), a higher rate of adverse unbalanced cytogenetic abnormalities, including complex changes, −5/5q- and/or −7/7q- (83% vs 28%; OR: 13.1; p<0.001) and a shorter overall survival (median, 12 vs 44 months; p<0.05).ConclusionsMyeloid neoplasm in the setting of CLL/CLL-like disease can be divided into two categories, one with prior treatment for CLL/CLL-like disease and the other without. CLL-type treatment may accelerate myeloid leukaemogenesis. The risk is estimated to be 13-fold higher in patients with treatment than those without. The causative agent could be attributed to fludarabine in combination with alkylators, based on the latency of myeloid leukaemogenesis and the cytogenetic profile.

Abstract Background Racial disparities in adverse perinatal outcomes have been studied in other countries, but little has been done for the Canadian population. In this study, we sought to examine the disparities in adverse perinatal outcomes between Asians and Caucasians in Ontario, Canada. Methods We conducted a population-based retrospective cohort study that included all Asian and Caucasian women who attended a prenatal screening and resulted in a singleton birth in an Ontario hospital (April 1st, 2015-March 31st, 2017). Generalized estimating equation models were used to estimate the independent adjusted relative risks and adjusted risk difference of adverse perinatal outcomes for Asians compared with Caucasians. Results Among 237,293 eligible women, 31% were Asian and 69% were Caucasian. Asians were at an increased risk of gestational diabetes mellitus, placental previa, early preterm birth (< 32 weeks), preterm birth, emergency cesarean section, 3rd and 4th degree perineal tears, low birth weight (< 2500 g, < 1500 g), small-for-gestational-age (<10th percentile, <3rd percentile), neonatal intensive care unit admission, and hyperbilirubinemia requiring treatment, but had lower risks of preeclampsia, macrosomia (birth weight > 4000 g), large-for-gestational-age neonates, 5-min Apgar score < 7, and arterial cord pH ≤7.1, as compared with Caucasians. No difference in risk of elective cesarean section was observed between Asians and Caucasians. Conclusion There are significant differences in several adverse perinatal outcomes between Asians and Caucasians. These differences should be taken into consideration for clinical practices due to the large Asian population in Canada.

BACKGROUND: The uterine junctional zone is the inner part of the myometrium. Dysfunction of the zone may underlie the pathogenesis of adenomyosis and its clinical manifestations, while biometric characteristics of the zone are currently considered as promising early diagnostic criteria for this disease. Adenomyosis has traditionally been associated with parity and intrauterine interventions, primarily in older patients. However, modern imaging tools often allow diagnosing the disease in young patients with infertility and an unburdened gynecological history. It is assumed that the detection of changes in the structure and function of the uterine junctional zone in adenomyosis can be the basis for predicting fertility outcomes and complications of pregnancy, as well as for the development of promising therapeutic strategies at the pregravid stage. AIM: The aim of this study was to assess the influence of biometric characteristics of the uterine junctional zone on pregnancy outcomes, depending on the parity and intrauterine interventions in patients with adenomyosis. MATERIALS AND METHODS: This prospective study included 102 patients aged 2239 years old with ultrasound features of adenomyosis who were going to conceive. The patients were divided into two groups: Group 1 (n = 58) consisted of nulliparous patients with no history of previous intrauterine interventions, and Group 2 (n = 44) comprised multipara women with a history of labor and / or intrauterine interventions. Using magnetic resonance imaging, we evaluated minimal, average and maximal junctional zone thicknesses, junctional zone deferential and a ratio of junctional zone thickness to myometrium thickness. Thresholds of biometric characteristics of the uterine junctional zone for adverse pregnancy outcomes were estimated. RESULTS: The frequencies of pregnancy and retrochorial hematoma in patients of Groups 1 and 2 in the first trimester of pregnancy did not differ significantly and amounted to 43.1% and 38.6%, 13.8% and 22.7%, respectively, p 0.05. Adverse pregnancy outcomes were diagnosed in 63.8% of patients in Group 1 and in 68.2% of patients in Group 2, p 0.05. In Group 1, the frequency of retrochorial hematoma depended on the initial junctional zone deferential, as well as on the initial average and maximal junctional zone thicknesses, junctional zone deferentials and ratios of junctional zone thickness to myometrium thickness, which, with an adverse pregnancy outcome, were 1.72.5 times higher than those in patients with a favorable outcome, p 0.05. In Group 2, adverse pregnancy outcomes were recorded with significantly higher values of average and maximal junctional zone thicknesses and junctional zone deferential. ROC curves were constructed using data of logistic regression analysis based on biometric characteristics of the uterine junctional zone to predict spontaneous abortion and infertility in patients with adenomyosis. CONCLUSIONS: Fertility outcomes in patients with adenomyosis depend on a complex of biometric characteristics of the uterine junctional zone as determined by magnetic resonance imaging.

Background: Fetal macrosomia has a major influence on maternal, neonatal and pregnancy outcomes.Objective: To describe the clinical and subclinical features and the management of fetal macrosomia on pregnancy outcomes. Subjects and methods: Study subjects including pregnant women and babies born ≥ 3500 g with nulliparous and over 4000 grams with primiparous or multiparous at Departement of Obstetrics and Gynecology in Hue University of Medicine and Pharmacy Hospital. The time of choosing subjects to enter the research group is that after birth, the weight is above 3500/4000 grams, then follow up the pregnancy result and retrospect the clinical and subclinical characteristics. Results: From May 2019 to April 2020, there were 223 pregnant women with the birth weight ≥ 3500 g in this study. The mean neonatal weight for macrosomia was 3869.96 ± 315.72 (g). The birth weight ≥ 4000 g, the rate of cesarean section was 91.5%, vaginal birth was 8.5%. The birth weight 3500 - under 4000 g, the rate of cesarean section was 76%, vaginal birth was 24%. 1.1% maternal complications was perineal tear. Conclusion:Factors related to fetal macrosomia: Maternal age, gender of fetus, parity, a history of fetal macrosomia, maternal height, pregnancy weight gain. Caesarean section is the majority. Key words: Fetal macrosomia, gestational diabetes mellitus, normal labor, caesarean section.

Miscarriage, particularly recurrent mid-trimester miscarriage is a distressful condition. This form of miscarriage and preterm birth appear to have some etiologies. An important etiology is cervical incompetence that describes a disorder in which painless cervical dilatation leads to recurrent second trimester pregnancy losses. Every year more than 10 million preterm birth occurs and more than 1 million baby die from this common complication of pregnancy. The incidence of true cervical insufficiency is estimated at less than 1% of the obstetric population. In the index pregnancy, findings indicative of possible cervical insufficiency include cervical funneling, cervical shortening, and overt cervical dilatation. The main objective of the study was to explore the benefit from cervical cerclage in pregnant women with cervical incompetence. This is a retrospective observational study conducted over a period of twelve months. All cases delivered in Central Hospital were assisted by consultant obstetricians, in which 16(61.5%) out of 26 cases were delivered by caesarean section. Miscarriage rate was 11.53%. Out of the caesarean deliveries 2(12.5%) were at term and 14(87.5%) were at preterm. In this study 3(21.42%) babies born at 32nd and 33rd weeks, 6(42.85%) at 34th week and 2(14.28%) were at 35th week. There was no fetal loss. Extreme low birth weight was only one, 7(43.75%) of the babies had normal body weight for the area of study, 8 babies (50%) had low birth weight. The cervical cerclage procedure therefore should be available more widely to benefit those patients with proven or strongly suspected cervical incompetence.Faridpur Med. Coll. J.

Recent studies indicated a high prevalence of hyperglycemia in non-diabetic patients presenting with acute coronary syndrome (ACS). However, the threshold of admission glucose (AG) as a predictor of adverse events in ACS is unclear. Objective The aim of this study was to assess the threshold of admission glucose (AG) as a predictor of adverse events including Major Acute Cardiac Events (MACE) and mortality, during the first week of admitting patients presenting with ACS. Material and Methods The data of 551 patients with ACS were extracted and evaluated. Patients were stratified according to their blood glucose on admission into three groups: group 1: <7 mmol/L (n = 200, 36.3%) and group 2: >7 mmol/L and <15 mmol/L (n = 178, 32.3%) and group 3: ≥15 mmol/L (n = 173, 31.4%). Stress hyperglycemia was arbitrarily defined as AG levels > 7 mmol/L (group 2 and 3). Patients with ACS were sub-divided into two groups: patients with unstable angina (UA, n = 285) and those with ST segment elevation myocardial Infarction (STEMI, n = 266) and data were analyzed separately using multiple regression analysis. Results The mean age of patients was 59.7 ± 14.8 years and 63% were males. The overall mortality in the population was 8.5% (5.4% in STEMI and 3.1% in UA) patients. In STEMI patients, the odds ratio of stress hyperglycemia as predictor of mortality in group 3 compared with group 1 was 3.3 (CI 0.99-10.98, P < 0.05), while in group 2 compared with group 1 was 2.4 (CI: 0.75-8.07, P = 0.065) after adjustment for age and sex. Similarly, in UA patients, the odds ratio of stress hyperglycemia in group 3 compared with group 1 was 2.7 (CI 0.37-18.98, P < 0.05), while in group 2 compared with group 1 was 2.4 (CI: 0.4-15.2, P = 0.344) after adjustment for age and sex. The incidence of more than 2 MACE in both STEMI and UA patients was higher in group 3 compared with the other two groups. Regression analysis showed that history of DM, high level of LDL cholesterol, high level of HbA1c, and anterior infarction were significant predictors of adverse events while other risk factors such as BMI, history of hypertension and smoking were of no significance. Conclusion This study indicates that the stress hyperglycemia on admission is a powerful predictor of increased major adverse events and hospital mortality in patients with acute coronary syndrome.

OBJECTIVE: In preterm newborn infants transfused with erythrocytes stored up to 28 days, to compare the reduction of blood donor exposure in two groups of infants classified according to birth weight. METHODS: A prospective study was conducted with preterm infants with birth weight <1000g (Group 1) and 1000-1499g (Group 2), born between April, 2008 and December, 2009. Neonates submitted to exchange transfusions, emergency erythrocyte transfusion, or those who died in the first 24 hours of life were excluded. Transfusions were indicated according to the local guideline using pediatric transfusion satellite bags. Demographic and clinical data, besides number of transfusions and donors were assessed. . Logistic regression analysis was performed to determine factors associated with multiple transfusions. RESULTS: 30 and 48 neonates were included in Groups 1 and 2, respectively. The percentage of newborns with more than one erythrocyte transfusion (90 versus 11%), the median number of transfusions (3 versus 1) and the median of blood donors (2 versus 1) were higher in Group 1 (p<0.001), compared to Group 2. Among those with multiple transfusions, 14 (82%) and one (50%) presented 50% reduction in the number of blood donors, respectively in Groups 1 and 2. Factors associated with multiple transfusions were: birth weight <1000g (OR 11.91; 95%CI 2.14-66.27) and presence of arterial umbilical catheter (OR 8.59; 95%CI 1.94-38.13), adjusted for confounders. CONCLUSIONS: The efficacy of pediatrics satellites bags on blood donor reduction was higher in preterm infants with birth weight <1000g.
