Abstract

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive-aged women. A recent study found that many obstetrics and gynecology (ObGyn) practicing physicians are unaware of the Rotterdam criteria recommended for diagnosis. Our objective was to identify gaps in trainee knowledge of PCOS diagnostic criteria and management. An online survey was sent out to US ObGyn physicians-in-training in 2018. The primary outcomes were identification of at least one component of each Rotterdam criteria (Rot-3): (1) oligomenorrhea/amenorrhea, (2) clinical or biochemical hyperandrogenism, and (3) ovarian volume or antral follicle count, and identification of all five components (Rot-5). Secondary outcomes were identification of comorbidities and management of PCOS. Multivariable logistic regression was used controlling for gender, seniority (PGY) status, program type, completion of an REI rotation, and number of PCOS patients seen. 85.4% of 347 trainees completing the survey reported using Rotterdam criteria to diagnose PCOS. However, only 55% identified Rot-3 and less than 10% identified Rot-5. Seniority (PGY4 OR 2.2; 95% CI: 1.2–4.1; p?=?.01) and completion of REI rotation (OR 1.8 95% CI: 1.2, 1.8; p?=?.006) were associated with identifying Rot-3. Similar findings were noted with identifying Rot-5. Our study identified significant gaps in knowledge regarding PCOS, suggesting an urgent need for improving strategies for trainee education to increase patient satisfaction and provide comprehensive care.  相似文献

Background

Nutrition specialists are considered key members of multicomponent pediatric weight management intervention teams, but to date, their contribution has not been quantified.

Objective

The purpose of this systematic review was to estimate the effectiveness of interventions provided by treatment teams that include a nutrition specialist on pediatric weight management outcomes, including body mass index (BMI), BMI z score, and waist circumference when compared with treatment teams that do not include a nutrition specialist.

Methods

The results of a comprehensive literature search and a systematic and more targeted update of that search were included in the meta-analyses: a search of controlled trials published between July 2005 and April 2012, conducted during the 2015 Pediatric Weight Management Update Project of the Academy of Nutrition and Dietetics Evidence Analysis Library, and an update search of controlled trials published between May 2012 and December 2015 focusing on a more specific topic within the previous search. Studies included overweight and/or obese patients aged 6 to 18 years receiving outpatient weight management treatment. Data extraction of all studies identified was performed using a standardized tool. The resulting data from the search and the systematic update were merged. Ninety-nine studies and 209 study arms were included in the analysis. An exploratory meta-analysis using alternative meta-analytic methods designed for complex, heterogenous interventions was conducted to identify relative contributions by intervention provider category at selected time points. Meta-regression analyses were used to evaluate significant differences from the reference category for each provider category.

Results

The nutrition specialist-only condition resulted in increased reductions in BMI z score compared with behavioralist-only, combined nutrition specialist and behavioralist, and neither nutrition specialist or behavioralist category (reference) throughout the analysis. Meta-regression analysis indicated that the difference in BMI z score between the nutrition specialist-only category and the reference category was significant at 3 to <6 months, 6 months to <1 year, and 1-year to 2-year time points (P=0.01, P=0.05, and P=0.01, respectively). There were smaller increases in BMI over time for the nutrition specialist-only provider category compared with reference categories, and this difference was significant at the 3 to <6 months and 1-year to 2-years time points (P=0.001 and P=0.05, respectively). There were no significant differences among provider categories for waist circumference at any time point.

Conclusions

Indirect evidence indicated that pediatric weight management outcomes for BMI z score and BMI at selected time points appeared to be better when a nutrition specialist was involved in delivering care.  相似文献

Three new diketopiperazine derivatives (DKPs), saroclazines A–C (13) along with three known DKPs (46) were isolated from mangrove-derived fungi Sarocladium kiliense HDN11-84. Saroclazines A–B (1 and 2) possessed a free amide structure, which was first found in sulfur-containing aromatic DKPs. Their structures were elucidated by NMR, HRESIMS and X-ray. The cytotoxic activity of new compounds (13) was tested against HeLa cell lines, among which compound 2 showed an IC50 value of 4.2 µM.  相似文献
