Oxidative stress (OS) is a condition that occurs as a result of an imbalance between the production of reactive oxygen species (ROS) and the body’s ability to detoxify and neutralize them. It can play a role in a variety of reproductive system conditions, including polycystic ovary syndrome (PCOS), endometriosis, preeclampsia, and infertility. In this review, we briefly discuss the links between oxidative stress and PCOS. Mitochondrial mutations may lead to impaired oxidative phosphorylation (OXPHOS), decreased adenosine triphosphate (ATP) production, and an increased production of ROS. These functional consequences may contribute to the metabolic and hormonal dysregulation observed in PCOS. Studies have shown that OS negatively affects ovarian follicles and disrupts normal follicular development and maturation. Excessive ROS may damage oocytes and granulosa cells within the follicles, impairing their quality and compromising fertility. Impaired OXPHOS and mitochondrial dysfunction may contribute to insulin resistance (IR) by disrupting insulin signaling pathways and impairing glucose metabolism. Due to dysfunctional OXPHOS, reduced ATP production, may hinder insulin-stimulated glucose uptake, leading to IR. Hyperandrogenism promotes inflammation and IR, both of which can increase the production of ROS and lead to OS. A detrimental feedback loop ensues as IR escalates, causing elevated insulin levels that exacerbate OS. Exploring the relations between OS and PCOS is crucial to fully understand the role of OS in the pathophysiology of PCOS and to develop effective treatment strategies to improve the quality of life of women affected by this condition. The role of antioxidants as potential therapies is also discussed.

Diet and nutrition are fundamental in maintaining the general health of populations, including women’s health. Health status can be affected by nutrient deficiency and vice versa. Gene–nutrient interactions are important contributors to health management and disease prevention. Nutrition can alter gene expression, as well as the susceptibility to diseases, including cancer, through several mechanisms. Gynecological diseases in general are diseases involving the female reproductive system and include benign and malignant tumors, infections, and endocrine diseases. Benign diseases such as uterine fibroids and endometriosis are common, with a negative impact on women’s quality of life, while malignant tumors are among the most common cause of death in the recent years. In this comprehensive review article, a bibliographic search was performed for retrieving information about nutrients and how their deficiencies can be associated with gynecological diseases, namely polycystic ovary syndrome, infertility, uterine fibroids, endometriosis, dysmenorrhea, and infections, as well as cervical, endometrial, and ovarian cancers. Moreover, we discussed the potential beneficial impact of promising natural compounds and dietary supplements on alleviating these significant diseases.

This article provides a detailed review of current knowledge on the role of vitamin D and its receptor in the biology and management of uterine fibroids (UFs). Authors present ideas for future steps in this area. A literature search was conducted in PubMed using the following key words: “uterine fibroid” and “vitamin D”. The results of the available studies, published in English from January 2002 up to April 2018, have been discussed. Vitamin D is a group of steroid compounds with a powerful impact on many parts of the human body. This vitamin is believed to regulate cell proliferation and differentiation, inhibit angiogenesis, and stimulate apoptosis. Nowadays, hypovitaminosis D is believed to be a major risk factor in the development of UFs. In many studies vitamin D appears to be a powerful factor against UFs, resulting in inhibition of tumor cell division and a significant reduction in its size, however, the exact role of this compound and its receptor in the pathophysiology of UFs is not fully understood. According to available studies, vitamin D and its analogs seem to be promising, effective, and low-cost compounds in the management of UFs and their clinical symptoms, and the anti-tumor activities of vitamin D play an important role in UF biology. The synergy between vitamin D and selected anti-UF drugs is a very interesting issue which requires further research. Further studies about the biological effect of vitamin D on UF biology are essential. Vitamin D preparations (alone or as a co-drugs) could become new tools in the fight with UFs, with the additional beneficial pleiotropic effect.

Background: Cesarean section is a surgical procedure, which is the most frequently performed in gynecology and obstetrics. It is commonly believed that an operative delivery is a less painful and safer mode of delivery, which translates into an increasing number of the procedures performed without medical indications. The maternal sequelae of cesarean sections are well elucidated and widely discussed in the literature, while long-term neonatal consequences still remain the issue of research and scientific dispute. The aim of the present paper was to perform a systematic review of current literature regarding pediatrics consequences of cesarean section. Methods: We reviewed available data from PubMed, Science Direct as well as Google Scholar bases concerning early and long-term neonatal sequelae of operative deliveries. The following key words were used: “cesarean section”, “caesarean section”, “neonatal outcomes”, “respiratory disorders”, “asthma”, “obesity”, “overweight”, and “neurological disorders”. A total of 1636 papers were retrieved out of which 27 were selected for the final systematic review whereas 16 articles provided data for meta-analysis. Statistical analyses were performed using RevMan 5.4. To determine the strength of association between the caesarean section and respiratory tract infections, asthma, diabetes type 1 as well as obesity the pooled odds ratios (OR) with the 95% confidence intervals (CI) were calculated. Results: Conducted meta-analyses revealed that caesarean section is a risk factor for respiratory tract infections (pooled OR = 1.30 95%CI 1.06–1.60, p = 0.001), asthma (pooled OR = 1.23 95%CI 1.14–1.33, p < 0.00001) as well as obesity (pooled OR = 1.35 95%CI 1.29–1.41, p < 0.00001) in offspring. Conclusions: The results of the studies included indicated that children delivered by cesarean section more commonly developed respiratory tract infections, obesity and the manifestations of asthma than children delivered vaginally. The risk of developing diabetes mellitus type 1 or neurological disorders in offspring after caesarean section is still under discussion.

The human microbiome plays a crucial role in determining the health status of every human being, and the microbiome of the genital tract can affect the fertility potential before and during assisted reproductive treatments (ARTs). This review aims to identify and appraise studies investigating the correlation of genital microbiome to infertility. Publications up to February 2021 were identified by searching the electronic databases PubMed/MEDLINE, Scopus and Embase and bibliographies. Only full-text original research articles written in English were considered eligible for analysis, whereas reviews, editorials, opinions or letters, case studies, conference papers, and abstracts were excluded. Twenty-six articles were identified. The oldest studies adopted the exclusive culture-based technique, while in recent years PCR and RNA sequencing based on 16S rRNA were the most used technique. Regardless of the anatomical site under investigation, the Lactobacillus-dominated flora seems to play a pivotal role in determining fertility, and in particular Lactobacillus crispatus showed a central role. Nonetheless, the presence of pathogens in the genital tract, such as Chlamydia trachomatis, Gardnerella vaginalis, Ureaplasma species, and Gram-negative stains microorganism, affected fertility also in case of asymptomatic bacterial vaginosis (BV). We failed to identify descriptive or comparative studies regarding tubal microbiome. The microbiome of the genital tract plays a pivotal role in fertility, also in case of ARTs. The standardization of the sampling methods and investigations approaches is warranted to stratify the fertility potential and its subsequent treatment. Prospective tubal microbiome studies are warranted.

Introduction One of the key challenges regarding the management of twins involves choosing the optimal mode of delivery, which is strongly influenced by the final presentation of both fetuses. In cases of vertex–nonvertex pregnancies attempting the trial of vaginal delivery, external cephalic version (ECV) is one of possible management options. The main objective of this review was to collect and summarize available data in terms of the application of ECV in the population of nonvertex second twins. Material and Methods Using the PRISMA guidelines, we searched for original, English‐language studies investigating ECV in nonvertex second twins. The PubMed/MEDLINE, SCOPUS, and COCHRANE databases were searched until May 2024. Reviews, case reports, editorials, and conference papers were excluded from further analysis. Out of 260 papers retrieved, 10 were subjected to the final analysis in terms of success rates, modes of delivery, and adverse outcomes. Results The total number of ECVs was 289, with an overall success rate of 64.4%. In the group of successful versions, vertex vaginal delivery was achieved in 171 cases (91.9%). The incidence of adverse maternal and neonatal outcomes was low. Conclusions The purpose of this review was to consolidate and update the current knowledge regarding ECV in nonvertex second twins. Based on the results of this series of studies, ECV appears to be a reasonable management option. However, it is important to highlight several significant limitations. The primary concern is the lack of recent research in this field over the past three decades, with the most recent study in our review being published in 1998. Furthermore, the actual number of studies addressing this topic is relatively low, characterized by a retrospective nature and questionable methodologies. These limitations make it challenging to draw definitive conclusions for clinical practice. This is an important message for our community, emphasizing the need for further studies in this area, particularly randomized controlled trials, to evaluate the safety and success rate of vaginal twin delivery after ECV when the second twin presents in a nonvertex position. This review provides updated knowledge on the external cephalic version in non‐vertex second twins. Although the results suggest that the procedure seems reasonable, the low quality of the studies, and more importantly, the lack of recent research, are significant limitations. The key message is the urgent need for new, high‐quality research in this area, particularly to evaluate the safety and success rates of this procedure in clinical practice.

Uterine fibroids are the most common benign neoplasm of the female reproductive tract in reproductive age women. Their prevalence is age dependent and can be detected in up to 80% of women by the age of 50 years. Patients affected by uterine fibroids may experience a significant physical, emotional, social, and financial toll as well as losses in their quality of life. Unfortunately, curative hysterectomy abolishes future pregnancy potential, while uterine-sparing surgical and radiologic alternatives are variously associated with reduced long-term reproductive function and/or high tumor recurrence rates. Recently, pharmacological treatment against uterine fibroids have been widely considered by patients to limit uterine fibroid-associated symptoms such as heavy menstrual bleeding. This hormonal therapy seemed effective through blocking the stimulatory effects of gonadal steroid hormones on uterine fibroid growth. However, they are contraindicated in women actively pursuing pregnancy and otherwise effective only during use, which is limited because of long-term safety and other concerns. Accordingly, there is an urgent unmet need for safe, durable, and fertility-compatible non-surgical treatment options for uterine fibroids. In this review article, we cover the current pharmacological treatments for uterine fibroids including their comparable efficacy and side effects as well as emerging safe natural compounds with promising anti-uterine fibroid effects.

A Multicenter, Retrospective Comparison Study of Pregnancy Outcomes According to Placental Location in Placenta Previa Placenta previa is one of the most serious pregnancy complications, and may lead to significant maternal–fetal complications, including massive bleeding, the need for the early completion of pregnancy, and an increased risk of postpartum complications. Occurrence and Risk Factors of Cholestasis in Newborns with Hemolytic Disease—A Case–Control Study Neonatal cholestasis is a serious condition that may occur in newborns with hemolytic disease (HDFN), leading to impaired liver function and long-term health consequences. The case–control study conducted by Drozdowska-Szymczak et al. allowed for the identification of key risk factors conducive to the development of cholestasis in this population [13]. First-trimester screening plays a key role in identifying the risk of such complications. A scoping review by Machura et al. indicated increased risks of premature delivery, gestational hypertension, and urinary tract infections in women with renal colic [19]. [...]untreated renal colic may lead to intrauterine growth restriction and a low birth weight of the newborn.

Obesity is associated with inflammation, which can disturb genome stability. Tumor necrosis factor ( TNF-α ) polymorphism was found to affect TNF-α protein production and inflammation. Therefore, the present study illustrates the relationship between TNF-α polymorphism, the degree of inflammation assessed by serum high sensitivity C-reactive protein concentration (CRP-hs) and basal DNA damage in patients with obesity (BMI 30–34.9 kg/m 2 ) and control subjects with proper body mass (BMI < 25 kg/m 2 ). A total of 115 participants (75 obese premenopausal women; and 40 age-, and gender-matched controls) were included. Biochemical parameters (serum concentrations of total-cholesterol, HDL-cholesterol, LDL- cholesterol, triglycerides, glucose, apolipoprotein AI, CRP-hs) and endogenous DNA damage (determined by comet assay) were measured. TNF-α G-308A polymorphism (rs1800629) was analyzed by PCR-RFLP (PCR-restriction fragments length polymorphism). An effect of TNF-α genotype on serum CRP-hs concentration was noted ( p  = 0.031). In general, carriers of the rare A allele of the TNF-α G-308A polymorphism had significantly lower endogenous DNA damage and serum CRP-hs concentrations than GG homozygotes, however, the protective effect of the A allele was especially visible in non-obese women. Serum CRP-hs concentrations and levels of DNA damage (% DNA in tail) were significantly higher in obese than in controls ( p  = 0.001 and p  < 0.0001, respectively ) . The adjusted multiple linear regression analyses revealed a significant, independent impact of obesity on DNA damage ( p  = 0.00000) and no effect of other covariates i.e. age, TNF-α genotype and serum CRP-hs concentration. Our study showed that obesity has a significant impact on the levels of endogenous DNA damage. Obesity abolished the protective effect of A allele of the TNF-α G-308A polymorphism on DNA damage and on inflammation development observed in non-obese A allele carriers.

Indocyanine green (ICG) is a fluorescent agent which is characterized by a wide range of applications in the proper visualization of the operating field, differentiation of vital structures, and localization of lesions to be excised. An investigation and overview of novel approaches of indocyanine green in modern gynecological oncology was conducted, including ovarian cancer surgery with its compartmental approach and compartmental surgery in endometrial cancer. Ureteral visualization and perfusion, lymphography, lymph node transfers, or the localization of anastomotic leakage in bowel surgery are examples of applications aimed at reducing the risk of surgical complications and improving the patients’ quality of life. The general use of indocyanine green in lymph node detection, subcategorized and analyzed, is constantly improved and reviewed. A therapeutic approach with macromolecules is being tested in preclinical models. Early results could suggest the future application of indocyanine green not only in broad-sense imaging but also as a cytotoxic agent conjugated with macromolecules. Further studies on the application of indocyanine green in laparoscopy, open surgery, and finally as a curative cytotoxic agent are needed.
