Unveiling the Impact of COVID-19 on Ovarian Function and Premature Ovarian Insufficiency: A Systematic Review.

: Premature ovarian insufficiency (POI) is a disorder that affects women under the age of 40. It is characterized by decreased ovarian function, elevated gonadotropin levels, and decreased estradiol. SARS-CoV-2 disrupts ovarian function largely through oxidative stress, inflammation, and immunological dysregulation, which are enhanced by its entrance into ovarian tissues via ACE2 receptors.

Unlocking Fertility: How Nitric Oxide Pathways Connect Obesity and Reproductive Health-The Role of Bariatric Surgery.

This study examines the relationship between obesity, oxidative stress, and reproductive dysfunction. It focuses on the effects of sleeve gastrectomy on gene expression and hormone profiles in 29 women with severe obesity (BMI ≥ 40 kg/m). Pre- and post-surgical investigations revealed significant differences in major gene expressions and hormonal markers.

Incomplete Uterine Rupture During the Second Trimester of Pregnancy, Successful Management With Continued Gestation Until 37 Weeks: A Case Report.

Uterine rupture is rare but one of the most severe and fatal complications in obstetrics. Nonetheless, its presence in the second trimester is exceptionally rare, posing considerable difficulties for diagnosis and management. This case report demonstrates a 38-year-old woman with a history of a previous cesarean delivery who presented at 18 weeks of gestation at the emergency department with severe, acute onset abdominal pain at the right iliac fossa.

Bariatric Surgery as a Molecular Modulator: The Role of FSHR Polymorphisms in Enhancing eNOS Expression and Reproductive Hormone Dynamics in Women with Severe Obesity.

Background/objectives: Severe obesity (BMI > 40 kg/m) has a severe influence on vascular health and reproduction. This study looks at how bariatric surgery affects endothelial nitric oxide synthase (eNOS) expression and reproductive hormone regulation across different follicle-stimulating hormone receptor (FSHR) polymorphism groups in women with extreme obesity.

Methods: Twenty-nine women with extreme obesity had bariatric surgery.

Nitrate-Nitrite-Nitric Oxide Pathway, Oxidative Stress, and Fertility Outcomes in Morbidly Obese Women Following Bariatric Surgery: A Systematic Review.

Obesity reduces nitric oxide (NO) production due to endothelial nitric oxide synthase (eNOS) dysfunction, resulting in oxidative stress, mitochondrial dysfunction, and chronic inflammation. These factors have a negative impact on reproductive health, including oocyte quality, endometrial receptivity, and embryo implantation. When oxidative stress affects eNOS function, the nitrate-nitrite-nitric oxide (NO-NO-NO) pathway provides an alternate route for NO production.

Investigation of cardiac remodeling and cardiac function on fetuses conceived via artificial reproductive technologies: a review.

The prevalence of artificial reproductive technologies (ART), such as intra-uterine insemination (IUI), fertilization (IVF), and intracytoplasmic sperm injection (ICSI), has surged in response to the global increase in infertility rates, now impacting 17.5 % of couples. With over nine million babies born through ART, the safety and efficacy of these methods are largely recognized; however, emerging concerns regarding their association with prenatal and long-term health risks, especially cardiovascular disease (CVD), necessitate a thorough examination.

Survival outcomes of endometrial cancer patients with disease involving the lower uterine segment: A meta-analysis.

Objectives: Lower uterine segment (LUS) involvement is encountered in a small proportion of endometrial cancer patients and is associated with aggressive histological features. Despite the available evidence, there seems to be a lack of consensus concerning its actual impact on disease related survival.

Study Design: The search strategy involved the Medline, Scopus, Clinicaltrials.

Search for Soft Unclustered Energy Patterns in Proton-Proton Collisions at 13 TeV.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

Safety of Obstetric Ultrasound: Mechanical and Thermal Indexes-A Systematic Review.

: Obstetric ultrasound is one of the most commonly used imaging modalities during pregnancy to detect any fetal abnormalities. The aim of this systematic review was to appraise all available scientific literature and summarize current evidence regarding the safety of fetal ultrasound by using the thermal index (TI) and mechanical index (MI). : We applied the PRISMA guidelines in order to prepare the review, and a 2-step process was performed in order to evaluate the available literature and decide which studies to be included.

Central Precocious Puberty During the COVID-19 Pandemic Period: A Systematic Review of Literature.

Central precocious puberty (CPP) is a condition where the hypothalamus-pituitary-gonadal axis is activated earlier than normal, leading to premature development of secondary sexual characteristics before eight years of age in girls and nine years of age in boys. The purpose of this study was to critically and systematically evaluate the literature regarding CPP rise during the COVID-19 pandemic. We searched PubMed and Google Scholar for relevant articles using the following MeSH terms: "COVID-19, "precocious puberty," "early puberty," "pediatric endocrinology," and "pandemic effects.

Comparing Perinatal Outcomes of Assisted Reproductive Technology (ART)-Induced vs. Naturally Conceived Twin Pregnancies.

The occurrence of multiple pregnancies is consistently and significantly linked to the growing use of assisted reproductive technology (ART). Even very young women opt for having multiple embryos implanted by medical professionals in order to increase the chances of a successful outcome. Our aim is to review the research on cesarean section rates and perinatal outcomes, like perinatal morbidity, risk of preterm delivery, and low birth weight (LBW) of neonates in multiple pregnancies that resulted from ART in comparison to those that were naturally conceived.

Factors Influence Breastfeeding Duration after High Risk and Low Risk Pregnancies.

Background: Breastfeeding provides vital nutrients and fosters maternal-infant bonding, benefiting both mother and child. However, breastfeeding duration is influenced by various factors, especially in women of high-risk pregnancy. This study aims to identify predictors of breastfeeding duration among women of high-risk and low-risk pregnancy, focusing on exclusive and mixed feeding practices.

Cervical length evolution in pregnancy and prediction of preterm delivery.

Purpose: To construct reference charts for cervical length (CL) in pregnancy based on longitudinal measurements and to assess the value of measuring cervical length after 24 weeks of gestation.

Methods: CL was measured transvaginally in singleton pregnancies at 5 to 41 weeks. Pregnancies with more than one measurement were used for creating the CL chart, whereas any measurement after 24 weeks was considered for assessing the correlation of CL with preterm delivery.
