Delivery in water, experiences in a population of Mexican women in Mexico City

Background: Labor is a physiological process during which the fetus, the membranes, the umbilical cord and the placenta are expelled from the uterus and water delivery has become popular, although its prevalence is unknown, it is supported by healthy women with full-term pregnancies, without complications; although there is insufficient evidence to support or discourage it. Objective: To identify obstetric and neonatal outcomes and complications in women who delivered in water and to compare them with traditional deliveries. Material and methods: It is a retrospective, observational and cross-sectional study, where 2486 women were included from a database of 4223 women assisted from 2004 to 2020 in private hospitals; Of the 2486 patients included, 1025 had a water delivery and 1461 had a conventional delivery, discarding 1737 women who underwent caesarean section from the study. The information obtained from the patients, their data obtained for this study were kept in the anonymity of the patients, where they were analyzed: non-parametric data reported in percentages using Chi square; Parametric, perinatal and neonatal data are reported as mean plus standard deviation (±SD) and analyzed using Student's T, using the SPSS version 25 statistical package. Results: A total of 2486 women were included in this study, the birth in 1025 was water delivery (24%) and 1461 was conventional delivery (35%), 1737 caesarean section (41%) were excluded from the study, no difference was observed maternal age; unlike weight, height, body mass index; they were higher in women with water birth compared to conventional. No difference was demonstrated between nulliparous (45.99%) and multiparous (53.86%) when comparing both birth in water and conventional; only increase in previous caesarean sections (9.36 vs 6.5%, p=0.008) and decrease in previous abortions (16.19 vs 20.94%, p=0.002) in water delivery with the conventional one; complications were not different: administration of oxytocin (3.2 vs 3.1) or postpartum hemorrhage (0.29 vs 0.13) in both deliveries; no differences in first degree perineal tears (21.4 vs 18.5%). Conclusion: Water birth reduces stress, pain sensation, second and third degree perineal lacerations and contributes to better newborn outcomes; the selection and inclusion of patients with low-risk pregnancies allows better perinatal results than conventional delivery; but, further studies are required to use it routinely.

Non-gestational primary choriocarcinoma of the ovary. Presentation of a clinical case

Background: Ovarian germ cell tumors are derived from the primordial germ cells of the ovary, they can be benign or malignant. Non-gestational ovarian choriocarcinoma is extremely rare and aggressive that are of gestational or non-gestational origin, its prevalence is less than 0.6% of all ovarian germ cell tumors. Due to the rarity of the tumor, there is a lack of information on the clinical-pathological characteristics, diagnosis and treatment. Objective: present a case of non-gestational ovarian choriocarcioma and review of the literature Clinical case: We present the case of a 20-year-old woman who presented with an acute abdomen, due to abdominal pain and distention, with scant vaginal bleeding and pain on cervical mobilization; An ultrasound was performed with a right annex with a lesion measuring 114 x83x79mm and a total volume of 394cc, heterogeneous with linear images inside punctiform and human chorionic beta-gonadotropin levels, elevated 112.337 mUI/mL, the patient underwent an exploratory laparotomy with the finding of an ovarian tumor; performing salpingo-oophorectomy and the histopathological report of the definitive surgical specimen and immunohistochemical study, the diagnosis of non-gestational ovarian choriocarcinoma was made. Conclusion: Non-gestational choriocarcinoma is an extremely rare malignant neoplasm that can present clinically in different ways, even as an acute abdomen, which requires differential diagnoses and management is the combination of surgery and adjuvant chemotherapy.

Anti-breast cancer drug screening based on Neural Networks and QSAR model

Breast cancer is one of the most lethal cancers, estrogen receptor α Subtype (ERα) is an important target. The compounds that able to fight ERα active may be candidates for treatment of breast cancer. The drug discovery process is a very large and complex process that often requires one selected from a large number of compounds. This paper considers the independence, coupling, and relevance of bioactivity descriptors, selects the 15 most potentially valuable bioactivity descriptors from 729 bioactivity descriptors. An optimized back propagation neural network is used for ERα, The pharmacokinetics and safety of 15 selected bioactivity descriptors were verified by gradient lifting algorithm. The results showed that these 15 biological activity descriptors could not only fit well with the nonlinear relationship of ERα activity can also accurately predict its pharmacokinetic characteristics and safety, with an average accuracy of 89.92~94.80%. Therefore, these biological activity descriptors have great medical research value.

Fluorescent sentinel lymph node mapping with icg in endometrial cancer. An initial experience in Argentina

Background: Near-infrared fluorescence-based sentinel lymph node (SLN) mapping technique with indocyanine green (ICG) has been found a useful surgical modality for sentinel node detection and disease staging in endometrial cancer (EC) worldwide. Objective: We aimed to introduce the SNL mapping technology using ICG and Near Infrared (NIR) fluorescence in Argentina. We aimed to assess the overall and bilateral detection rate of ICG based SNL mapping along with verifying its feasibility and effectiveness in surgical staging. We also aimed to discover the perceptions of surgeons regarding the use of ICG as a tracer and NIR as light-medium in SNL mapping. Method: ICG SLNs identification was evaluated retrospectively. This study was performed at the Hospital Aleman de Buenos Aires in September, 2017The detection rates were calculated along with the analysis of the number of SNL observed and operative time, and time taken by overall surgery. Subsequently, the surgeons were interviewed to ascertain their opinion of using ICG SNL mapping in endometrial cancer staging. Results: Four patients with endometrial cancer were included for analysis. The overall and bilateral detection rates have been 100% and 75%, respectively. While, under white light, no SLNs were identified. The average operative time of nodes resection was estimated 2.15 minutes. The fluorescence has been used for 2.2 minutes and overall time taken by surgery was estimated 71.5 minutes. The estimated blood loss (EBL) has been lower than 50 ml. The responses of surgeons’ from the interview have been 100% positive. The cost of the procedure based on the amount of dye used was 25 dollars per patient. Conclusion: Laparoscopic ICG SLN resulted to be feasible, practical and no expensive surgical modality for uterine cancer triage.

Anesthesia for cesarean in pregnant with uncorrected failot tetralogy

Tetralogy of Fallot is the most common cyanotic congenital heart disease. Hemodynamic changes can cause serious and fatal multi-organ complications, the choice of anesthesia is very difficult.Combined spinal epidural techniques have become an alternative to traditional neuraxial interventions; the advantages of spinal or subarachnoid block are fused with the flexibility of the epidural technique; they offer a fast, effective and minimally toxic spinal block, improve inadequate block, and prolong the duration of anesthesia with epidural supplements.The purpose of this article is to report the case of a pregnant woman with a diagnosis of uncorrected Tetralogy of Fallot and the anesthetic technique of effective establishment without producing harmful hemodynamic changes for the mother-child binomial.

Two modified natural in vitro fertilisation (IVF) protocols compared to conventional IVF treatment: Retrospective data from one Danish Fertility Centre

Aim of study: Over the last decade, laboratory procedures in in vitro fertilisation (IVF) have improved. Hyperstimulated ovaries cause an overload of surplus embryos. The present study was designed to evaluate the efficiency of two different modified IVF cycle protocols trying to reduce the load of medication used for IVF: simple IVF (S-IVF), Tamoxifen 40 mg daily from day 2 in the cycle to ovulation induction) and mild IVF (M-IVF), Tamoxifen 40 mg daily and every secondary 150 IU Gonal F until ovulation induction. The study aims to evaluate their efficiency compared with our conventional IVF (C-IVF) using a short antagonist protocol. Methods: A retrospective cohort study including all patients admitted to IVF for unexplained infertility, tubal factor, and male factor. In all stimulated cycles patients aimed at having fresh embryos transferred and surplus good embryos cryopreserved. All patients were recruited in the same period and allocated to the different treatments on their own request. The study was conducted between June 2019 and February 2021. Results: In total the study included 976 IVF cycles. 651 cycles from C-IVF, 145 cycles from S-IVF and 180 cycles from M-IVF. Mean age in the groups were comparable. Mean number of eggs retrieved was 6.1 (C-IVF), 1.2 (S-IVF) and 3.0 (M-IVF). Pregnancy rate per fresh transfer was found to be 29% for C-IVF, 26% in the S-IVF group and for the M-IVF 20%. Conclusion: Modified IVF stimulation protocols may be an important step towards a simpler assisted reproductive technology (ART) approach. More tolerable for women, easier and cheaper for patients and society they maintain acceptable clinical pregnancy rates. Large prospective studies need to be performed in the future.

Hysteroscopic evaluation of uterine cavity in women with unexplained infertility

Objective: To detect missed uterine abnormalities on primary work up in unexplained infertile women. Study design: An observational study was performed in the outpatient infertility clinic of Beni-Suef University Hospitals. It included 100 women with unexplained infertility. Diagnostic office hysteroscopy was done for all participants. Women were grouped according to the infertility type and compared as regards uterine abnormalities detected. Results: Uterine abnormalities were detected by hysteroscopy in 29% of women. No significant difference was found regarding the hysteroscopic findings between primary and secondary infertility groups. However, uterine polyp cases were detected more in women with primary infertility (55.5% /18). A significant difference in intrauterine adhesions between both groups being detected only in secondary infertility group (p value =0.006). Conclusion: Outpatient preliminary and routine diagnostic office hysteroscopy may be a beneficial part of a primary and secondary infertility workup.

Reproductive and neonatal outcomes in women with unicornuate uterus: a population-based study

Objective: To investigate reproductive and neonatal outcomes in women with unicornuate uterus. Study design: Data from the Health Care Cost and Utilization Project-Nationwide Inpatient Sample database were extracted from 2010 through 2014 to create a delivery cohort using ICD-9 codes. Code 752.33 was used to identify cases with unicornuate uterus and reproductive outcomes were compared to pregnancies without unicornuate uterus. A multivariate logistic regression model was used to adjust for statistically significant variables (P-value<0.05). Results: Among 3,850,226 deliveries during the study period, 802 women had unicornuate uterus. Patient with unicornuate uterus were more likely to be older (P<0.001), have thyroid disease (P<0.001), previous Caesarean section (P<0.001), and to have had in-vitro fertilization (IVF) (P<0.001). The risk of gestational diabetes, pregnancy induced hypertension, gestational hypertension and preeclampsia were significantly greater in the unicornuate uterus group relative to controls, after controlling for baseline risk factors; aOR 1.32 [95% CI 1.03–1.71], aOR 1.46 [95% CI 1.16–1.85], aOR 1.16 [95% CI 1.22-2.28] and aOR 1.70 [95% CI 1.24-2.32], respectively. Also, the rates of preterm delivery, preterm premature rupture of membranes and caesarean section were higher in the unicornuate uterus group compared to controls after controlling for confounding factors, aOR 3.83 (95% CI 3.19–4.6), aOR 5.11 (95% CI 3.73–7.14) and aOR 11.38 (95% CI 9.16–14.14) respectively. At birth, 11.1% and 2.6% of neonates were small for gestational age in the unicornuate uterus and the control groups, respectively, aOR 4.90, (95% CI 3.87-6.21). Conclusion: Women with unicornuate uterus are at higher risk for pregnancy complications, preterm delivery and having small for gestation age neonates. Women with known unicornuate uterus may benefit from increased surveillance to prevent and/or decrease maternal and neonate morbidity and mortality.

Thyroid dysfunction in pregnancy: practical perspective

Pregnancy is a complex endocrine and metabolic status in life of women, therefore role of the thyroid physiology during this period will be profoundly affected, this has been attributed to the complex interplay of Human chorionic gonadotrophin that acts as TSH receptors’ stimulant, more estrogen is produced by placenta will lead to rise in the serum level of Thyrogublin binding protein, change in iodine homeostasis, and hemodynamic changes. From 12th -16th week of pregnancy, the fetus is entirely dependent on the thyroid status of the mother, therefore any disruption in this metabolic milieu will lead to negative outcomes on both the fetus and the mother. Therefore, the current guidelines have stressed on appropriate management of thyroid dysfunction in pregnancy with particular interest on early pregnancy, a critical period for neurocognitive development, then throughout the pregnancy and postpartum period (Figure 1).

Audit of maternal deaths at the Saint Louis regional hospital from 2017 to 2019

Objective: To audit maternal deaths at the regional hospital center of Saint-Louis. Materials and methods: This was a retrospective cross-sectional study of all maternal deaths that occurred between January 1, 2017 and December 31, 2019 at the Saint-Louis regional hospital center. Data were entered on EXCEL 2013 software. Analysis was performed on Epi Info version 3 software. Results: During our study, 73 cases of maternal death were collected. Maternal mortality was 520 per 100 000 live births. The mean age of the patients was 28.1 years±6.8. Multiparous women accounted for 43.8% and nulliparous women for 1.3%. The causes of maternal death were obstetric hemorrhage (28.77%), hypertension and its complications (20.55%), labour dystocia (15.07%) and anemia (6.85%). Direct obstetric causes of death were responsible for 64.38% of cases and indirect obstetric causes were seen in 35.62%. Death occurred postpartum in 68% of cases, during pregnancy in 25% and during labor in 7%. Death was preventable in 77.5% of cases. Conclusion: Maternal mortality is a real health problem in our practice. It affects young women. Indirect causes of death are becoming more significant causes of death in our practice. Maternal mortality is avoidable in the majority of cases.
