Objective: To assess the effects of body mass index (BMI) on the outcome of IVF cycles among poor responders.
Methods: A prospective cohort study in Egypt enrolled 185 poor responders who underwent intracytoplasmic sperm injection via an antagonist protocol between 2012 and 2017. Participants were classified into three groups by BMI (calculated as weight in kilograms divided by the square of height in meters): 18.5-24.9 (normal, n=48); 25-29.9 (overweight, n=54); 30 or higher (obese, n=83). Outcomes were clinical pregnancy rate, implantation rate, chemical pregnancy rate, gonadotropin dose, number of oocytes and embryos, and cancellation rate.
Results: There was no significant difference among the three groups in gonadotropin dose; duration of stimulation; endometrial thickness on trigger day; number of oocytes retrieved, injected, or fertilized; number of embryos, transferred embryos, or frozen embryos; or day of embryo transfer. Frequency of implantation (11/81 [14%] vs 6/96 [6%] or 5/155 [3%]), chemical pregnancy (20 [42%] vs 14 [30%] or 12 [14%]) and clinical pregnancy (15 [31%] vs 12 [22%] and 9 [11%]) was significantly higher for normal than for overweight or obese women, respectively.
Conclusion: Implantation, chemical pregnancy, and clinical pregnancy rates were inversely related to increasing BMI. CLINICALTRIALS.GOV: NCT03457233.

Objectives: As part of the "Japan Environment and Children's Study (JECS)," a national prospective birth cohort study, we examined the association between the maternal work environment and psychological distress during pregnancy in Japan.
Methods: Employing a cross-sectional design, we analyzed data from 42,797 participants, originally collected between 2011 and 2014. Associations between the maternal work environment and psychological distress (Kessler 6) were examined using generalized estimation equation models adjusted for confounding factors.

Objective: The effects of sex hormones remain largely unexplored in pheochromocytomas and paragangliomas (PPGLs) and gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
Methods: We evaluated the effects of estradiol, progesterone, Dehydroepiandrosterone sulfate (DHEAS), and testosterone on human patient-derived PPGL/GEP-NET primary culture cell viability (n = 38/n = 12), performed next-generation sequencing and immunohistochemical hormone receptor analysis in patient-derived PPGL tumor tissues (n = 36).
Results: In PPGLs, estradiol and progesterone (1 µm) demonstrated overall significant antitumor effects with the strongest efficacy in PPGLs with NF1 (cluster 2) pathogenic variants.

Although several environmental factors may increase the risk of nervous system anomalies, the association between exposure to particulate matter with an aerodynamic diameter of ≤ 2.5 μm (PM) and nervous system anomalies is not completely understood. This study aimed to examine the association between expoure to PM and nervous system anomalies, including specific phenotypes during preconception and early pregnancy and determine the crucial time windows.

Objective: To investigate the association between an abnormal hysterosalpingogram (HSG) and obstetrical and neonatal outcomes.
Design: A retrospective cohort study comparing outcomes between women with normal versus abnormal tubal patency and uterine cavity on HSG.
Results: Among 2181 women included in the study, 494 (22.
