RESUMEN
INTRODUCTION: The prevalence of diabetes mellitus has increased tremendously in the last two decades among women of reproductive age and this is mainly due to the pandemic of obesity. Diabetes mellitus is a well-known cause of maternal and neonatal complications in pregnancy. Diabetic nephropathy is a marker of severe diabetes and results in organ damage. However, only a small number of studies have evaluated the implications of diabetic nephropathy on pregnancy complications, with most having 50 to 100 nephropathy subjects. Our study aims to compare pregnant women with diabetes mellitus complicated by nephropathy or not and evaluate the relationship with obstetrical and perinatal morbidity and mortality, on a larger population. METHODS: This was a population-based study using data from the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample (HCUP-NIS) including women who delivered between 2004 and 2014. Multivariate logistic regression was used to control for confounding effects. RESULTS: Among 86,615 pregnancies that were complicated by diabetes mellitus, 1,241 (1.4%) had diabetic nephropathy. Diabetic nephropathy was strongly associated with preeclampsia (aOR 2.3, 95% CI 1.90-2.68), as well as chronic hypertension with superimposed preeclampsia or eclampsia (aOR 4.2, 95% CI 3.53-5.01), preterm birth (aOR 1.8, 95% CI 1.59-2.1), and blood transfusion (aOR 3.6 95% CI 2.82-4.46). Both groups were similar in age and income. CONCLUSION: Diabetic nephropathy is associated with increased obstetrical and perinatal morbidity compared to diabetes mellitus alone. These patients may benefit from a high dose of folic acid, more vigilant antenatal surveillance, delivery in a tertiary care center, and more rigorous screening and prevention methods for pregnancy-induced hypertension diseases at antenatal care visits.

OBJECTIVE: This study aims to determine the effects of early and late onset estrogen supplementation on the immature oocyte retrieval, fertilization and clinical pregnancy rates in follicle stimulating hormone (FSH) and human chorionic hormone (hCG) primed in vitro maturation (IVM) cycles of the patients with polycystic ovary syndrome (PCOS). METHODS: This is a retrospective analysis of 161 patients with PCOS who underwent FSH and hCG primed IVM. Group 1 included 120 patients who received early onset estrogen supplementation while group 2 consisted of 41 patients who had late onset estrogen supplementation in primed IVM cycles. Immature oocyte (germinal vesicle and/or metaphase I) retrieval and fertilization rates were the primary outcomes, whereas clinical pregnancy and live rates were the secondary outcomes. RESULTS: Group 1 patients had significantly higher body mass index and more previous IVF attempts (p = 0.001 and p = 0.008, respectively). All of the retrieved oocytes from the PCOS patients were either germinal vesicle or metaphase I oocytes and there were no metaphase II oocytes among the retrieved oocytes. Both groups had statistically similar numbers of metaphase I and fertilized oocytes (p > 0.05 for both). However, group 1 patients had significantly lower number of germinal vesicle oocytes but significantly higher number of metaphase II oocytes (p = 0.001 for both). Both groups had statistically similar fertilization (85.0% vs 78.0%), clinical pregnancy (49.2% vs 43.9%) and live birth (37.5% vs 39.0%) rates (p > 0.05 for all). CONCLUSION: Early onset estrogen supplementation appears to improve the quality of retrieved immature oocytes and contribute to the maturation of oocytes in stimulated IVM cycles.

PURPOSE: This study sought to compare sperm DNA fragmentation (SDF) in semen specimens after 3 days and then after 3 h of abstinence in men presenting for initial infertility evaluation. METHODS: A prospective cohort study of 112 men undergoing their first semen analysis as part of an infertility work-up was conducted. All participants presented with 3 days of abstinence for a semen analysis and DNA-fragmentation test. Both tests were repeated on a second sample collected 3 h after the first ejaculation. DNA-fragmentation was evaluated with the halo test by one of two technicians blinded to duration of abstinence. Variables analyzed include ejaculate volume, sperm concentration and motility, smoking status, cannabis use, initial specimen DNA fragmentation, and use of sperm-directed anti-oxidant formulations. RESULTS: Among all subjects, DNA fragmentation improved in the 3-h abstinence specimen (34.6 ± 19.4% vs. 23.7 ± 16.0%, p = 0.0001). Among subjects with high DNA fragmentation (> 35%) on the initial specimen, 55% improved into the normal range. Semen volume and sperm concentration decreased (3.1 ± 3.3 ml vs. 1.9 ± 0.8 ml, p < 0.01 and 41 ± 39 vs. 32 ± 31 (millions/ml), p = 0.01), while progressive motility tended to increase. Fifty-eight subjects demonstrated ≥ 30% improvement in SDF in the second specimen as compared to the first. Factors found to correlate with > 30% improvement in DNA fragmentation in the 3-h abstinence specimen compared to 3 days were younger age and use of anti-oxidants. CONCLUSION: High SDF can often be managed with a second ejaculation 3 h after the first in infertile couples, including in males with abnormal semen analyses per the 2010 WHO guide. Apart from SDF levels, changes in sperm quality were not clinically significant in the second specimen and did not increase rates of ICSI. However, a second ejaculation after 3 h probably may reduce the necessity of costly and/or invasive ART strategies.

Federal guidelines recommend that food with hormone content fall below 1% of endogenous production in the subset of the population with the lowest daily production. The majority of dairy products are obtained from pregnant cows, which increase the level of hormones present. The purpose of this article was to perform theoretical evaluation of the quantity of progesterone in cow's milk based on fat percentages and to assess whether this was within the recommended range. Daily recommended dairy product intake from various countries worldwide was researched. This was compared to the concentration of progesterone previously identified in varying fat contents of cow origin milk to assess the amount of progesterone (mg/day) that would be consumed if the guidelines were followed. The maximum daily progesterone consumption suggested will be met by ingestion of 2.7 L, 1.42 L, 1.13 L, 940 mL, 810 mL, 650 mL of 0% (skim), 1%, 2%, 3.25%, 10% (cream), and 35% (whipping cream) fat liquid cow origin dairy product, respectively. Therefore, ingestion of the highest amount of recommended daily dairy intake fell below 1% of the daily endogenous quantity produced, except in the unlikely case of consumption of 650 mL of 35% fat. Studies demonstrating an effect of cow's liquid dairy product intake may need to be revisited, since levels of progesterone consumption remain within the recommended levels. However, it should be considered that ingestion of cow's milk might have a potential effect on the hormonal profile in patients; however, this seems unlikely.
