Follicular fluid high density lipoprotein-associated micronutrient levels are associated with embryo fragmentation during IVF

To investigate whether follicular fluid lipid-soluble micronutrients are associated with embryo morphology parameters during IVF. Follicle fluid and oocytes were obtained prospectively from 81 women. Embryo morphology parameters were used as surrogate markers of oocyte health. HDL lipids and lipid-soluble micronutrients were analyzed by high-pressure liquid chromatography. Non-parametric bi-variate analysis and multivariable ordinal logistic regression models were employed to examine associations between biochemical and embryo morphology parameters. Follicular fluid HDL cholesterol (r = −0.47, p < 0.01), α-tocopherol (r = −0.41, p < 0.01), δ-tocopherol (r = −0.38, p < 0.05) and β-cryptoxanthine (r = −0.42, p < 0.01) are negatively correlated with embryo fragmentation. Ordinal logistic regression models indicate that a 0.1 μmol/L increase in β-cryptoxanthine, adjusted for γ-tocopherol, is associated with a 75% decrease in the cumulative odds of higher embryo fragmentation (p = 0.010). Follicular fluid HDL micronutrients may play an important role in the development of the human oocyte as evident by embryo fragmentation during IVF

The genomic landscape of balanced cytogenetic abnormalities associated with human congenital anomalies

Despite the clinical significance of balanced chromosomal abnormalities (BCAs), their characterization has largely been restricted to cytogenetic resolution. We explored the landscape of BCAs at nucleotide resolution in 273 subjects with a spectrum of congenital anomalies. Whole-genome sequencing revised 93% of karyotypes and demonstrated complexity that was cryptic to karyotyping in 21% of BCAs, highlighting the limitations of conventional cytogenetic approaches. At least 33.9% of BCAs resulted in gene disruption that likely contributed to the developmental phenotype, 5.2% were associated with pathogenic genomic imbalances, and 7.3% disrupted topologically associated domains (TADs) encompassing known syndromic loci. Remarkably, BCA breakpoints in eight subjects altered a single TAD encompassing MEF2C, a known driver of 5q14.3 microdeletion syndrome, resulting in decreased MEF2C expression. We propose that sequence-level resolution dramatically improves prediction of clinical outcomes for balanced rearrangements and provides insight into new pathogenic mechanisms, such as altered regulation due to changes in chromosome topology

Obesity and depression are risk factors for future eating disorder-related attitudes and behaviors in women with polycystic ovary syndrome.

Objective(s)To identify clinical predictors of future eating disorder symptoms in women with polycystic ovary syndrome (PCOS).DesignProspective cohort study.SettingUniversity center.Patient(s)One hundred sixty-four women with PCOS by the Rotterdam criteria.Intervention(s)Participants were characterized at a baseline visit between 2006 and 2017. A questionnaire including the validated Eating Disorder Examination-Questionnaire (EDE-Q) was self-administered at follow-up.Main outcome measure(s)EDE-Q global score (0-6, higher scores indicate more severe symptoms).Result(s)One hundred sixty-four women completed the follow-up survey an average of 5.3 years after the baseline visit. Compared with a normative population, women with PCOS had higher EDE-Q global scores (2.3 vs. 1.5) and scored higher on all subscales. Within the PCOS cohort, the following baseline clinical characteristics were independently predictive of scoring in the highest EDE-Q global score tertile: body mass index, waist circumference, hyperandrogenemia, high sensitivity C-reactive protein, and depression scores. Obesity at baseline conferred a 6.9-fold increase in the odds of elevated EDE-Q score (adjusted odds ratio = 6.89; 95% confidence interval, 2.70, 17.62), while a positive depression screen conferred 3.6-fold increased odds (adjusted odds ratio = 3.58; 95% confidence interval, 1.74-7.35). Compared with white women, nonwhite women were at risk of higher EDE-Q scores.Conclusion(s)Women with PCOS are at risk of disordered eating attitudes and behaviors, which may interfere with attempts at lifestyle interventions. Clinicians should screen women with PCOS for eating disorder psychopathology, especially those with obesity or depression. An exclusive focus on weight loss may have unintended consequences

A higher prevalence of endometriosis among Asian women does not contribute to poorer IVF outcomes

PurposeThe purpose of the study was to determine whether diagnosis of endometriosis or endometriosis with endometrioma influences in vitro fertilization (IVF) outcomes in an ethnically diverse population.MethodsWomen undergoing a first IVF cycle (n = 717) between January 1, 2008 and December 31, 2009, at a university-affiliated infertility clinic, were retrospectively assessed for an endometriosis diagnosis. Differences in prevalence of endometriosis by ethnicity were determined, as well as differences in IVF success by ethnicity, with a focus on country of origin for Asian women. A multivariate model was generated to assess the relative contributions of country of origin and endometriosis to chance of clinical pregnancy with IVF.ResultsEndometriosis was diagnosed in 9.5% of participants; 3.5% also received a diagnosis of endometrioma. Endometriosis prevalence in Asian women was significantly greater than in Caucasians (15.7 vs. 5.8%, p < 0.01). Women of Filipino (p < 0.01), Indian (p < 0.01), Japanese (p < 0.01), and Korean (p < 0.05) origin specifically were more likely to have endometriosis than Caucasian women, although there was no difference in endometrioma presence by race/ethnicity. Oocyte quantity, embryo quality, and fertilization rates did not relate to endometriosis. Clinical pregnancy rates were significantly lower for Asian women, specifically in Indian (p < 0.05), Japanese (p < 0.05), and Korean (p < 0.05) women, compared to Caucasian women, even after controlling for endometriosis status.ConclusionsThe prevalence of endometriosis appears to be higher in Filipino, Indian, Japanese, and Korean women presenting for IVF treatment than for Caucasian women; however, the discrepancy in IVF outcomes was conditionally independent of the presence of endometriosis. Future research should focus on improving pregnancy outcomes for Asian populations whether or not they are affected by endometriosis, specifically in the form of longitudinal studies where exposures can be captured prior to endometriosis diagnoses and infertility treatment
