RESUMO

CONTEXT: Type 2 diabetes (T2D) is reduced in postmenopausal women randomized to estrogen-based hormone therapy (HT) compared with placebo. Insulin sensitivity is a key determinant of T2D risk and overall cardiometabolic health, and studies indicate that estradiol (E2) directly impacts insulin action. OBJECTIVE: We hypothesized that the timing of E2 administration after menopause is an important determinant of its effect on insulin action. DESIGN: We performed a randomized, crossover, placebo-controlled study. PARTICIPANTS: Study participants were early postmenopausal (EPM; ≤ 6 years of final menses; n = 22) and late postmenopausal (LPM; ≥ 10 years since last menses; n = 24) women naive to HT. INTERVENTION: Study interventions included short-term (1 week) transdermal E2 and placebo. MAIN OUTCOMES AND MEASURES: The study's main outcome was insulin-mediated glucose disposal (glucose disposal rate [GDR]) via hyperinsulinemic-euglycemic clamp. RESULTS: Compared to EPM women, LPM women were older (mean ± SD; 63 ± 3 vs 56 ± 4 years, P < .05) and more years past menopause (12 ± 2 vs 3 ± 2 years, P < .05). Body mass index (24 ± 3 vs 25 ± 7 kg/m(2)) and fat mass (25 ± 7 vs 23 ± 6 kg) did not differ between groups, but fat-free mass (FFM) was lower in LPM women compared to EPM women (40 ± 4 vs 43 ± 5 kg, P < .05). Baseline GDR did not differ between groups (11.7 ± 2.8 vs 11.5 ± 2.9 mg/kg FFM/min). In support of our hypothesis, 1 week of E2 decreased GDR in LPM women compared to an increase in EPM women (+0.44 ± 1.7 vs - 0.76 ± 2.1 mg/kg FFM/min, P < .05). CONCLUSIONS: There was not an apparent decline in GDR with age or time since menopause per se. However, E2 action on GDR was dependent on time since menopause, such that there was an apparent benefit early (≤ 6 years) compared to harm later (≥ 10 years) in menopause. E2-mediated effects on insulin action may be one mechanism by which HT reduces the incidence of T2D in early postmenopausal women.

RESUMO

Providing quality prenatal care to high-risk, pregnant adolescents represents an important challenge to health care providers and health plans. Using national prenatal care guidelines, this study sought to evaluate the quality of important processes and outcomes of prenatal care delivered to women age 21 years and younger enrolled in three health plans serving the Connecticut Medicaid population. Some important findings include 93% compliance with recommended processes of prenatal care, an 11% C-section rate, an average length of hospital stay of 4.0 days for women having a C-section, and a 10% premature delivery rate. Opportunities for improvement include 40% failing to begin prenatal care in the first trimester, 31% not receiving the recommended number of prenatal care visits, and 8% delivering a low-birth-weight infant. This study provides important descriptive information on processes and outcomes of care for pregnant adolescents within Medicaid Managed Care and also identifies opportunities for improvement.

RESUMO

BACKGROUND: Many states have enrolled Medicaid beneficiaries in managed care organizations (MCOs). Few assessments of the quality of asthma care provided by these new programs are available. OBJECTIVE: To describe the quality of care provided to asthmatic Medicaid children enrolled in MCOs. METHODS: For this cross-sectional survey, a chart abstraction tool was developed to evaluate fulfillment of key performance measures chosen from a national guideline for asthma diagnosis and management. These measures were prescription of an inhaled anti-inflammatory medication, accomplishment of patient education, evaluation of exposure to environmental triggers of asthma, and administration of influenza vaccination. From State of Connecticut administrative databases, a random sampling of Medicaid children, ages 5 to 18 years, enrolled in four MCOs was selected. Chart entries from July 1, 1996 to June 30, 1997 were reviewed using the abstraction tool. Accomplishment of performance measures was evaluated for the total sample and for children who were high utilizers of medical services (at least one ED visit or hospitalization during the study period). RESULTS: For 80 high utilizers among 315 children, completion of performance measures was suboptimal: 46% were prescribed inhaled steroids; an action plan was outlined for 43%; evaluation of patient or family tobacco use was documented for 56%; evaluation of the presence of a pet for 43% or mite exposure for 19%; and allergy skin testing or RAST was accomplished for 15%. CONCLUSIONS: This information suggests that opportunities exist to improve the quality of care for these children.
