Recent years have witnessed an increase in the prevalence of maternal obesity during pregnancy in the United States and worldwide. Obese women have increased risks for gestational problems, such as diabetes, hypertension, and pre-eclampsia. Further, gestational obesity can adversely impact fetal growth and result in macrosomia, congenital abnormalities, and even fetal death. Measures must be taken to reduce maternal adiposity, as even a modest weight loss during pregnancy is beneficial for the health of mothers and fetus. Calorie restriction and moderate exercise are proven safe methods of stopping weight gain and/or inducing white-fat loss in these subjects. Additionally, therapeutic drugs that activate the AMP-activated protein kinase signaling pathway may be effective in ameliorating pathological conditions in obese patients. Finally, dietary supplementation with L-arginine or its effective precursor (L-citrulline) may be beneficial for managing overweight or obese gestating women by reducing white-fat accretion. Because of ethical concerns over human studies, animal models (e.g., sheep, pigs, baboons, rats, and mice) are warranted to test novel hypotheses with enormous biological significance and clinical applications.

Background: The purpose of this article is to illustrate the application of an evidence-based, structured performance measurement methodology to identify, prioritize, and (when appropriate) generate new measures of health care quality, using primary care as a case example. Primary health care is central to the health care system and health of the American public; thus, ensuring high quality is essential. Due to its complexity, ensuring high-quality primary care requires measurement frameworks that can assess the quality of the infrastructure, workforce configurations, and processes available. This paper describes the use of the Productivity Measurement and Enhancement System (ProMES) to compile a targeted set of such measures, prioritized according to their contribution and value to primary care. Methods: We adapted ProMES to select and rank existing primary care measures according to value to the primary care clinic. Nine subject matter experts (SMEs) consisting of clinicians, hospital leaders and national policymakers participated in facilitated expert elicitation sessions to identify objectives of performance, corresponding measures, and priority rankings. Results: The SMEs identified three fundamental objectives: access, patient-health care team partnerships, and technical quality. The SMEs also selected sixteen performance indicators from the 44 pre-vetted, currently existing measures from three different data sources for primary care. One indicator, Team 2-Day Post Discharge Contact Ratio, was selected as an indicator of both team partnerships and technical quality. Indicators were prioritized according to value using the contingency functions developed by the SMEs. Conclusion: Our article provides an actionable guide to applying ProMES, which can be adapted to the needs of various industries, including measure selection and modification from existing data sources, and proposing new measures. Future work should address both logistical considerations (e.g., data capture, common data/programming language) and lingering measurement challenges, such as operationalizating measures to be meaningful and interpretable across health care settings.
