A preconception weight loss intervention eliminates the adverse metabolic oral contraceptive effects and, compared with oral contraceptive pretreatment, leads to higher ovulation rates.
Both weight loss and OCP use result in significant improvements in several physical and mental domains related to quality of life, depressive symptoms, and anxiety disorders, and combined therapies offer further benefits in overweight/obese women with PCOS.
These data show the benefit of improved ovulation and live birth with delayed infertility treatment with clomiphene citrate when preceded by lifestyle modification with weight loss compared with immediate treatment. Pretreatment with oral contraceptives likely has little effect on the ovulation and live birth rate compared with immediate treatment.
Ovulation persists despite morbid obesity and the changes from bypass surgery. Reproductive function after surgery is characterized by a shortened follicular phase and improved female sexual function.
Objective
To address the lack of predictors of IVF success by using proteomic biometrics.
Design
Experimental study of follicular fluid specimens from a prospective cohort of IVF patients.
Setting
Academic research laboratory and IVF program.
Patient(s)
Women ≤32 years old with <11 oocytes retrieved and no pregnancy were matched to women who had ≥ 11 oocytes and live birth (10 pairs). Year of cycle start and IVF down-regulation protocol were also matched.
Intervention(s)
Follicular fluid was separated by two-dimensional polyacrylamide gel electrophoresis followed by Sypro Ruby staining and comparison with PDQuest software. Logistic regression was incorporated to calculate the likelihood of live birth in relation to the protein spot of interest.
Main Outcome Measure(s)
Protein markers.
Result(s)
Liquid chromatography–tandem mass spectrometry and searching of sequence databases revealed 11 potential protein candidates. Haptoglobin alpha, predominantly fetal expressed T1 domain, mitochondrial integrity genome (ATPase), apolipoprotein H (beta-2 glycoprotein I), dihydrolipoyl dehydrogenase, lyzozyme C, fibrinogen alpha-chain, and immunoglobulin heavy chain V-III (region BRO) were found to have increased expression in the live birth group, whereas antithrombin, vitamin D–binding protein, and complement 3 were decreased. An ELISA confirmed a significantly lower level of antithrombin.
Conclusion(s)
Proteomic evaluation of follicular fluid is able to identify potential biomarkers of good versus poor responders in matched pairs of IVF patients.
Background
Women with polycystic ovarian syndrome have a high prevalence of metabolic syndrome and type 2 diabetes mellitus. Blacks and Hispanics have a high morbidity and mortality due to cardiovascular disease and diabetes mellitus in the general population. Since metabolic syndrome is a risk factor for development of type 2 diabetes and cardiovascular disease, understanding any racial and ethnic differences in metabolic syndrome amongst women with polycystic ovarian syndrome is important for prevention strategies. However, data regarding racial/ethnic differences in metabolic phenotype amongst women with polycystic ovary syndrome is inconsistent.
Objective
To determine if there are racial/ethnic differences in insulin resistance, metabolic syndrome and hyperandrogenemia in women with polycystic ovarian syndrome.
Study Design
Secondary data analysis of a prospective multicenter, double blind controlled clinical trial, the Pregnancy in Polycystic Ovary Syndrome II study, conducted in 11 academic health centers. Data on 702 women with polycystic ovarian syndrome aged 18-40 years who met modified Rotterdam criteria for the syndrome and wished to conceive were included in the study.
Women were grouped into racial/ethnic categories
Non-Hispanic Whites, non-Hispanic Blacks and Hispanic. The main outcomes were the prevalence of insulin resistance, metabolic syndrome and hyperandrogenemia in the different racial/ethnic groups.
Results
BMI (35.1 ± 9.8 vs. 35.7 ± 7.9 vs. 36.4 ± 7.9 kg/m2) and waist circumference (106.5 ± 21.6 vs. 104.9 ± 16.4 vs. 108.7 ± 7.3 cm) did not differ significantly between non-Hispanic White, non-Hispanic Black and Hispanic women. Hispanic women with PCOS had a significantly higher prevalence of hirsutism (93.8 vs. 86.8%), abnormal free androgen index (FAI) (75.8 vs. 56.5%), abnormal homeostasis model assessment (HOMA) (52.3 vs. 38.4%) and hyperglycemia (14.8 vs. 6.5%), as well as lower sex hormone binding globulin compared to non-Hispanic Whites. Non-Hispanic Black women had a significantly lower prevalence of metabolic syndrome (24.5 vs. 42.2%) compared with Hispanic women, and lower serum triglyceride levels compared to both Hispanics and non-Hispanic Whites (85.7 ± 37.3 vs. 130.2 ± 57.0 vs. 120.1 ± 60.5 vs. mg/dL, p<0.01), with a markedly lower prevalence of hypertriglyceridemia (5.1 vs. 28.3 vs. 30.5%, p<0.01) compared to the other two groups.
Comment
Hispanic women with PCOS have the most severe phenotype, both in terms of hyperandrogenism and metabolic criteria. Non-Hispanic Black women have an overall milder polycystic ovarian syndrome phenotype than Hispanics and in some respects, than Non-Hispanic White women.
The robotic surgical platform is being utilized by a growing number of hospitals across the country, including academic medical centers. Training programs are tasked with teaching their residents how to utilize this technology. To this end, we have developed and implemented a robotic surgical curriculum, and share our initial experience here. Our curriculum was implemented for all General Surgical residents for the academic year 2014-2015. The curriculum consisted of online training, readings, bedside training, console simulation, participating in ten cases as bedside first assistant, and operating at the console. 20 surgical residents were included. Residents were provided the curriculum and notified the department upon completion. Bedside assistance and operative console training were completed in the operating room through a mix of biliary, foregut, and colorectal cases. During the fiscal years of 2014 and 2015, there were 164 and 263 robot-assisted surgeries performed within the General Surgery Department, respectively. All 20 residents completed the online and bedside instruction portions of the curriculum. Of the 20 residents trained, 13/20 (65 %) sat at the Surgeon console during at least one case. Utilizing this curriculum, we have trained and incorporated residents into robot-assisted cases in an efficient manner. A successful curriculum must be based on didactic learning, reading, bedside training, simulation, and training in the operating room. Each program must examine their caseload and resident class to ensure proper exposure to this platform.
