Effect of Per and Poly-Fluoroalkyl Substances on Pregnancy and Child Development.

BACKGROUND: Childhood obesity is significantly influenced by maternal exposure to Per- and Poly-Fluoroalkyl Substances (PFAS) during pregnancy. PFAS exposure occurs through the Peroxisome Proliferator-Activated Receptor (PPAR-γ) receptor, leading to increased fat deposition and profound health effects in child growth and development. Despite ongoing investigations, the relationship between maternal serum PFAS concentration and child obesity requires further exploration. OBJECTIVE: This study aimedto review the possible effects of Per and poly-fluoroalkyl substances exposure and their mechanism in overweight/obese children from pregnant ladies. METHODS: A detailed literature survey was conducted using online databases, including Science Direct, Google Scholar, Scopus, Cochrane, and PubMed. The study focused on the diverse effects of PFAS on maternal and child health, with particular emphasis on neurological complications. RESULTS: Child growth development depends upon breastfeeding and placenta health, which is disrupted by PFAS exposure, ultimately destroying the body mass index of the child. Neurotoxicity testing utilized the SH-SY5Y human-derived cell line as an in vitro model, revealing PFAS-induced increases in adipocyte number, reduced cell size, altered lipid conglomeration, increased adiposity, and changes in liver function. in vivo studies in mice and human cell lines indicated PPAR-γ and ER-α activation, leading to adiposity and weight gain through Estrogen signaling and Lipid metabolism. PFAS concentrations positively correlated in maternal sera, analyzed by liquid chromatography/quadrupole mass spectrometry. CONCLUSION: PFAS, with a long half-life of 3.5-8.5 years, is commonly found in the serum of pregnant women, crossing the placenta barrier. This exposure disrupts placental homeostasis, negatively impacting mechanisms of action and potentially leading to deterioration in pregnancy and child health. Further research is needed to comprehensively understand the complex interplay between PFAS exposure and its implications for maternal and child well-being.

Pharmacological investigation of vitamin E with combined oral contraceptives on INHBA gene against PCOS that intricate through melatonin PKC pathway.

The most prevalent endocrine and metabolic condition in women of reproductive age are polycystic ovary syndrome (PCOS) with significant risk factors such as circadian rhythm and melatonin disruption. The aim of this study is to assess the effect of vitamin E in combination with a combined oral contraceptive (COC) on continuous light-induced PCOS using hormonal measures, oxidative stress (OS) indicators, and the inhibin beta-A (INHBA) gene, which targets the melatonin protein kinase C (PKC) pathway. An in silico technique anticipated INHBA's binding affinity for vitamin E and COC. For the in vivo investigation (IAEC/240/2021), female SD rats were divided into six groups and subjected to a 16-week induction period, followed by a 2-month test drug treatment with drospirenone (DRSP) as a standard. Serum testosterone, FSH, melatonin, and OS were calculated as hormonal markers. The expression of the INHBA gene was studied to see if it could be linked to the circadian rhythm and OS via the melatonin PKC pathway. According to the in silico study, vitamin E and DRSP had higher binding energy for the INHBA (-8.6 kcal/mol and -8.4 kcal/mol, respectively). When compared to the control group, in vivo results showed a substantial decrease in testosterone levels (p = .05), as well as changes in FSH (p = .78) and melatonin (p = .13). IHNBA gene expression has also dramatically increased, stimulating FSH production in the pituitary gland. Vitamin E and COC concomitantly are beneficial against PCOS because it modulates OS, which in turn influences circadian rhythm and the melatonin PKC pathway.

Insights into Vitamin E with Combined Oral Contraceptive on INSR Gene in PCOS by Integrating In Silico and In Vivo Approaches.

Polycystic ovarian syndrome (PCOS) is a hormone disorder common among reproductive-aged women. This is associated with the symptoms like an irregular menstrual cycle, excess androgens, and polycystic ovary. Interestingly, vitamin E acts like the hormone progesterone and improves insulin sensitivity in PCOS. The study aims to evaluate the therapeutic effect of vitamin E in combination with combined oral contraceptive (COC) against PCOS by in silico and in vivo methods. The therapeutic effect of vitamin E (25 and 50mg/kg) in combination with COC (0.4mg/kg) was screened by the in silico method using Auto dock vina 4.2.6. Additionally, in vivo studies with a letrozole-induced PCOS model were performed in 30 female SD rats (n = 6 in each group) for 8 weeks with different doses of vitamin E. Furthermore, histopathological features and the insulin receptor (INSR) gene were scrutinized. An in silico study showed that drospirenone and vitamin E have an excellent affinity to bind to INSR and have higher binding energy (- 8.5 kcal/mol and - 8.7 kcal/mol, respectively). In vivo results showed a significant reduction in elevated testosterone levels compared to that of the PCOS group; follicle-stimulating hormone (FSH) and insulin levels also showed significant changes and reversed anti-oxidant levels in a dose-dependent manner. Ovarian histopathological changes were observed in different follicle counts in addition to the INSR gene, which showed changes in densitometry values. Supplementation of vitamin E combined with COC could be effective against PCOS, and clinical studies must be carried out further.

Oxalobacter formigenes reduce the risk of kidney stones in patients exposed to oral antibiotics: a case-control study.

This is the first prospective study to investigate the association between kidney stones, bone mineral density, serum testosterone, colon cancer and O. formigenes colonization. 40 kidney stone patients and 85 controls were enrolled. O. formigenes colonization was established. BMD was examined from T- and Z-scores using dual energy absorptiometry. O. formigenes was found in 28 of 40 cases and 80 of 85 controls. BMD was significantly reduced in patients (p < 0.05). The evaluation revealed a significant association between lowered O. formigenes colonization and low testosterone. Urinary calcium and oxalates levels were greater in patient. Serum testosterone and urinary citrate concentrations was reduced in patients with a significant difference. Also an association between O. formigenes and colon cancer was noted. Absence of O. formigenes might stand for a pathogenic factor in calcium oxalate stone, low bone mineral density, low testosterone levels and also colon cancer, when antibiotics are prescribed generously.
