The results of the 20 years studies of the presence in blood serum and other body fluids of endogenous modulators of adrenergic and M-cholinergic impact as a component of humoral link of autonomic nervous system. The article is devoted to the endogenous sensitizer of beta-adrenergic receptor (ESBAR) - water-soluble low molecular weight substances, analogs of which are histidine, tryptophan, tyrosine, mildronat and preductal. It is shown, that separate dilutions of human serum and animal (as a source of ESBAR) and analogs of ESBAR ways to enhance the effectiveness of activation of beta-adrenoceptors (AR) of smooth muscle (uterus, coronary and renal arteries, trachea, stomach), myocardium, erythrocytes and platelets (respectively influenced of histidine and tryptophan). It is reported that content of ESBAR in human serum (according to the titers of its dilution) depends on the sex and the presence of somatic diseases, and at women are also on the stage of reproduction and obstetric complications It is discussed possible mechanisms of ESBAR action, its physiological role, including as a component of beta-adrenoceptor inhibitory mechanism for myometrium, as well as the prospect of the use of analogs of ESBAR, including for the prevention of preterm labor, and for the treatment of bronchial asthma, coronary heart disease, hypertension and heart failure.

Changes in contemporary obstetric and gynaecological practice in relation to ultrasound cervical screening during pregnancy, the treatment of intra-epithelial cervical neoplasia and laparoscopic surgery have resulted in an increased utilization of trans-abdominal cervico-isthmic cerclage in an attempt to reduce the incidence of mid-trimester and early preterm birth in women with repeated pregnancy loss.
Intracerebral Hemorrhage of Brainstem in triple pregnancy after in vitro fertilization by receiving Ovum Donation: A case report and review
Published on: 16th December, 2019
Deliveries prior to 28 weeks’ gestation (extreme preterm birth) pose a global health concern, according to the World Health Organization (WHO). Extreme preterm birth is associated with several complications in the newborn and management in neonatal intensive care unit would incur high expenses. In parallel, advancements in in vitro fertilization will give an opportunity for women to conceive in cases of ovarian failure. At the same time, health providers also encourage patients to receive more than one embryo simultaneously during an embryo transfer. Here we report a case of a patient in coma condition of triplet pregnancy, post ovum donation with three-embryo transfer. Following stabilization, cranial computed tomography (CCT) was performed. The result showed bleeding in the brainstem and into intraventricular spaces at 25+4 gestation weeks. Furthermore, ICH during pregnancy is considered as a rare case in obstetrical field, especially involving the brainstem. This could lead to life-threatening conditions and serious disability in the future. On the fifth day of hospitalization, she suffered from pneumonia and pulmonary edema. On the eight day (26+5 gestations weeks), an emergency caesarean section was performed due to fully dilated of the cervix with breech presentation of all fetuses. Mother and the children survived with some non-life-threatening disabilities.
This is the very first case reported of intracerebral hemorrhage in the brainstem in triplet pregnancy after receiving ovum donation. Heterologous conception could be an iceberg phenomenon of gestational complications among the population. Reproductive tourism could still become greater in the future.

Bacterial vaginosis (BV) is associated with adverse pregnancy outcomes with various treatment options.
Objective: To compare the efficacy and effect on pregnancy outcome of Metronidazole and Clindamycin in women with bacterial vaginosis in Port Harcourt, Nigeria.
Methodology: Randomized controlled study of 136 pregnant women diagnosed with BV at the University of Port Harcourt Teaching Hospital. A structured proforma was used to obtain socio-demographic characteristics and other relevant data. Treatment was with either oral Metronidazole or oral Clindamycin for seven days. A secondary test and evaluation of the effect on adverse pregnancy outcomes were determined. Data analysis was done using the SPSS statistical package version 22.0
Results: BV prevalence was 23%, with similar cure rates with both medications. The failure rates of clindamycin and metronidazole were 10.4% and 13% respectively (p = 0.639). The mean gestational age at delivery in the metronidazole treated group was 38.67 weeks ± 1.69 compared to 38.68 weeks ± 1.64 in the oral clindamycin group (p = 0.96). Pre-labour rupture of membranes and preterm delivery rates with both medications were similar (p = 0.73; OR 1.3; 95% CI 0.3-4.9) and (p = 0.73; OR 1.3; 95% CI 0.3-4.9) respectively.
Conclusion: Both medications have comparable efficacy and similar pregnancy outcomes in the treatment of bacterial vaginosis in low-risk asymptomatic pregnant Nigerian women and thus can be used interchangeably.
Trial of labor after cesarean outcomes with excessive gestational weight gain
Published on: 6th May, 2020
OCLC Number/Unique Identifier: 8601973455
The success of vaginal birth after cesarean section (VBAC) has been correlated with a variety of maternal characteristics such as age, ethnicity, and body mass index (BMI, calculated as weight in kilograms divided by height in meters squared). The patient’s BMI just prior to delivery has been shown to be a better prognostic indicator of success than pre-pregnancy BMI. Gestational weight gain was previously associated with a decreased rate of successful VBAC. More recent research has not supported such an association. The objective of our study was to further validate these findings with a larger population.
We performed a retrospective cohort study of women undergoing trial of labor after cesarean (TOLAC) at our institution from January 2010 to December 2019. Women were divided into three groups based on weight gain in pregnancy as compared to the American College of Obstetrics and Gynecology (ACOG) recommendations (i.e. < 25 pounds (lbs), 25-35 lbs, > 35 lbs). We further subdivided the pregnancies between term and preterm deliveries. The primary outcome was a successful VBAC. Of 1087 patients attempting a TOLAC, 772 (71%) were successful and 315 (29%) failed VBAC. When grouped according to ACOG weight gain recommendations, 303 (31%) women were below ACOG guidelines, 318 (33%) met guidelines, and 339 (35%) exceeded guidelines. There was no difference in the rate of VBAC success among the three groups. When counseling patients, providers should still promote healthy dietary habits but should not correlate excess weight gain with chance of TOLAC success.
Retinopathy of prematurity - Intersibling divergence of risk factors among twins
Published on: 19th February, 2020
Retinopathy of prematurity (ROP) is a consequence of an arrest in normal retinal neural and vascular development, which determines the aberrant retinal regeneration [1,2].
ROP is a disease process mostly reported in preterm neonates ranging from mild, transient changes in the retina with regression to severe progressive vasoproliferation, scarring, detachment of retina and blindness and it is common blinding disease in children and a major cause of vision loss among preterm infants [3]. Today it is well known that oxygen therapy is not the single causative factor, but many other risk factors play a causative role in the pathogenesis of ROP [4,5].
The risk factors for ROP include oxygen administration, hypoxia, hypercapnia, blood transfusion exchange transfusion, apnea,sepsis and total parenteral nutrition. The incidence of ROP has been reported to be similar in multiple and singleton births [6-8]. Twin studies show that from 70% to 80% of the susceptibility to ROP is conditioned by genetic factors [9,10].
Hence this study is to find out the incidence of ROP in twins in a tertiary care centre in a developing country. It also attempts to identify the difference in risk factors among twins which predispose to ROP in Neonatal Intensive Care Unit.
Orgasmic coitus triggered stillbirth via placental abruption: A case report

Sexual activity during healthy pregnancy is safe. There are little data on how coital activity affects outcome of the high-risk pregnancies. Hereby we report a case demonstrating that orgasmic coitus triggered placental abruption resulting in preterm stillbirth.
A 38-year-old 8-para, 12-gravida woman lived unmarriedly with a constant partner in low socioeconomic conditions. Her previous pregnancies included 7 deliveries without complication, two early miscarriages and two pregnancy terminations. Her present pregnancy was complicated with gestational hypertension successfully treated with nifedipine. She had coitus 2 to 4 times a month, mostly without orgasm. The last coitus which happened in side-by-side position was accompanied by orgasm which continued in uterine hypertonicity and massive vaginal bleeding at 29 weeks gestation. Two hours subsequently, on admission to hospital, placental abruption and fetal demise were diagnosed. At the emergency cesarean section, a dead female infant weighing 1,510 g was born. Fetal pathology was not discovered. Placental histopathology showed retroplacental hematoma, intervillous and decidual hemorrhages, focal distal villous hypoplasia and avascular villuses. Patient’s recovery rapidly occurred after intensive care.
Placental abruption complicates 0.4% - 1.0% of deliveries. It is known that most cases of abruption cannot be predicted and prevented. Our report suggests that orgasmic coitus may be a trigger for placental abruption in those women who have gestational hypertension and multiple risks for placental abruption. We infer from the above case that sexual intercourse is advised to avoid during pregnancy of such women in order to prevent placental abruption.
Efficacy of intravenous immunoglobulins in the prophylaxis of neonatal sepsis
Published on: 14th April, 2021
OCLC Number/Unique Identifier: 9006870046
Despite critical care advances, robust antibiotic therapy and improved strategies in early detection and prevention of infection, the incidence of morbidity and mortality from neonatal sepsis worldwide in preterm and low birth weight neonates remains overwhelmingly high. Neonatal sepsis is characterised by a clinical syndrome of systemic signs of infection and bloodstream bacteraemia in newborns within the first months of life. The risk of sepsis in neonates is inversely proportional to gestational age and birth weight due to deficiency in humoral immunity and the need for more invasive supportive neonatal intensive care unit interventions. Adverse effects such as necrotising enterocolitis associated with antimicrobial therapy are serious enough to warrant exploration of alternative therapeutic strategies. Immunoglobulin replacement therapy offers hope of enhancing immune competence and reducing infection rates in vulnerable populations. It is evident from the relevant studies to date that the benefits offered by intravenous immunoglobulin prophylaxis may not be significant enough for routine hospital implementation. Further research to better understand the mechanisms underlying immunodeficiency will lead to the realisation of alternative therapeutic and prophylactic interventions.

Does change in cervical dilation after anesthesia impact latency after cerclage placement?
Published on: 24th April, 2023
Background: Pregnant individuals with early cervical dilation have a high risk for preterm birth. The authors encountered cases where cervical dilation increased after anesthesia administration for a cerclage. Objective: The primary objective was to assess if a change in cervical dilation after anesthesia administration for a cerclage was associated with a shorter latency to delivery. Study design: This was a retrospective chart review of pregnancies from January 1, 2011, to December 31, 2021, who had a cerclage and delivered at our institution. Maternal demographics, obstetrical history, operative details, and delivery information were collected. Multi-fetal gestations, un-indicated cerclages, and abdominal cerclages were excluded. The primary outcome was the difference in cervical dilation between the office and the operating room after spinal anesthesia administration. A multivariable regression was performed. Results: A total of 183 pregnancies were included. The mean gestational age at cerclage placement was 18 weeks (STDEV 3.6). Twenty-nine percent of patients (53/183) were more dilated in the operating room compared to the office The latency between cerclage and delivery was not different if there was a cervical change between these settings (p = 0.655). There was an increased risk for preterm delivery with dilation in the office (OR 1.01, CI 1.01 to 2.5), but not with dilation in the operating room (OR 1.4, CI 0.9 to 2.0). Conclusion: Cervical dilation between the office and the operating room is different. Pregnancies with more dilation delivered at earlier gestations. However, a change in dilation between the office and the operating room was not associated with a shorter latency.
Neonatal Mortality Rate among Twin and Singleton Births with the Gestational Age of 34-37 Weeks: A Population-Based Study
Published on: 28th June, 2023
Introduction: Twin pregnancy, compared to a singleton pregnancy, is associated with a higher risk of preterm birth and other neonatal complications. This study aimed to compare neonatal mortality rates and risk factors among births with the gestational age of 34 weeks - 37 weeks in twin and singleton pregnancies.Methods: The study design was cross-sectional and population-based. We extracted the data from the birth information registry in Iran. Mothers' and neonates' information was removed from the registry systems between 2018 and 2020. We used Statistical R software to compare neonatal mortality rate, demographic variables, and risk factors between two groups of twin and singleton neonates.Results: Out of 579,873 live births with a gestational age of 34 weeks - 37 weeks, 729 (1.4/1000) singleton and 54(0.77/1000) twins (one out of two) neonates died in the delivery room in the first hour of life. Of the neonates who left the delivery room alive, 3129 (4.9 per 1000) neonates had died (5.7/1000 singleton and 3.04/1000 twin). The neonatal mortality rate in hospitalized singleton neonates (1.85%) was higher than twin group (1.06%). After adjustment of other variables, the mortality rate in twin pregnancy was significantly lower than in singletons (p value < 1/1000), with an odds ratio of 0.47 (CI: 0.39 - 0.55). Antenatal corticosteroid treatment in the twin group was significantly higher than in singletons.Conclusion: Twin neonatal mortality rate was lower than singletons in the neonates with gestational age 34 weeks - 37 weeks. Clinicians could consider these results for delivery timing in uncomplicated twin pregnancies. Antenatal corticosteroid therapy can be considered to reduce the mortality rate of late preterm neonates in resource-limited countries.
Antioxidants and Pregnancy Complications: Exploring Therapeutic Strategies for Better Outcomes
Published on: 25th January, 2024
Pregnancy complications present significant challenges, impacting maternal health and fetal development. Oxidative stress, a key contributor to various pregnancy-related disorders such as preeclampsia, gestational diabetes mellitus (GDM), and preterm birth, has spurred interest in exploring antioxidant interventions. Antioxidants, known for their ability to counteract oxidative damage, have emerged as potential therapeutic agents to mitigate these complications. This paper synthesizes current knowledge on the role of antioxidants in pregnancy, elucidating their mechanisms of action, sources, and impact on oxidative stress-related complications. It examines diverse antioxidant compounds, including vitamins C and E, selenium, and natural phytochemicals, highlighting their potential to modulate oxidative stress pathways and promote maternal-fetal well-being. Furthermore, this paper critically analyzes clinical studies, meta-analyses, and preclinical research exploring the efficacy and safety of antioxidant supplementation during pregnancy. It discusses the complexities surrounding optimal dosages, timing, and formulations of antioxidants, aiming to delineate strategies for their integration into prenatal care. In conclusion, this review provides insights into the promising role of antioxidants as therapeutic strategies to alleviate pregnancy complications associated with oxidative stress. It highlights avenues for future research, advocating for a deeper understanding of antioxidant mechanisms and their optimal utilization in prenatal care to enhance maternal and fetal health outcomes.
COVID-19 Pneumonia in Pregnancy: A Retrospective Study on Maternal and Neonatal Outcomes
Published on: 8th April, 2024
Objective: To identify risk factors among pregnant with COVID-19 for adverse outcomes related to disease severity, maternal mortality, and morbidity.Materials and methods: In this retrospective study, 45 pregnant patients with COVID-19 pneumonia were confirmed by RT-PCR. The inclusion criteria were pregnant patients diagnosed with COVID-19 confirmed by RT-PCR and hospitalized in the gynecology-obstetrics and intensive care unit. Exclusion criteria were non-pregnant patients and pneumonia cases with unconfirmed COVID-19 causes. The study used SPSS software to analyze the data. Results: Our study recorded 45 cases of SARS-CoV-2 infection in pregnant women over 2.5 years. The age group most affected was 20-35 years, with 75% of cases. 57% of patients had no known comorbidities. 88.8% of patients were symptomatic at diagnosis. Almost 30% of patients required admission to the ICU, with 60% requiring oxygen supplementation. The study recorded 36 live births (80%), of which 26 cases (72.2%) required no further care and had a favorable outcome.Conclusion: Pregnant women with medical conditions are at higher risk of severe COVID-19, which can cause respiratory distress syndrome and impact delivery and neonatal outcomes. Preventive measures are important.
