RESUMO
BACKGROUND: Nearly half of Americans with diagnosed hypertension have uncontrolled blood pressure (BP) while some integrated healthcare systems, such as Kaiser Permanente Northern California, have achieved control rates upwards 90%. METHODS AND RESULTS: We adapted Kaiser Permanente's evidence-based treatment protocols in a racially and ethnically diverse population at 12 safety-net clinics in the San Francisco Health Network. The intervention consisted of 4 elements: a hypertension registry, a simplified treatment intensification protocol that included fixed-dose combination medications containing diuretics, standardized BP measurement protocol, and BP check visits led by registered nurse and pharmacist staff. The study population comprised patients with hypertension who made ≥1 primary care visits within the past 24 months (n=15 917) and had a recorded BP measurement within the past 12 months. We conducted a postintervention time series analysis from August 2014 to August 2016 to assess the effect of the intervention on BP control for 24 months for the pilot site and for 15 months for 11 other San Francisco Health Network clinics combined. Secondary outcomes were changes in use of guideline-recommended medication prescribing. Rates of BP control increased at the pilot site (68%-74%; P<0.01) and the 11 other San Francisco Health Network clinic sites (69%-74%; P<0.01). Statistically significant improvements in BP control rates (P<0.01) at the 11 San Francisco Health Network clinic sites occurred in all racial and ethnic groups (blacks, 60%-66%; whites, 69%-75%; Latinos, 67%-72%; Asians, 78%-82%). Use of fixed-dose combination medications increased from 10% to 13% (P<0.01), and the percentage of angiotensin-converting enzyme inhibitor prescriptions dispensed in combination with a thiazide diuretic increased from 36% to 40% (P<0.01). CONCLUSIONS: Evidence-based system approaches to improving BP control can be implemented in safety-net settings and could play a pivotal role in achieving improved population BP control and reducing hypertension disparities.

Importance: Neural tube defects are among the most common major congenital anomalies in the United States and may lead to a range of disabilities or death. Daily folic acid supplementation in the periconceptional period can prevent neural tube defects. However, most women do not receive the recommended daily intake of folate from diet alone. Objective: To update the 2009 US Preventive Services Task Force (USPSTF) recommendation on folic acid supplementation in women of childbearing age. Evidence Review: In 2009, the USPSTF reviewed the effectiveness of folic acid supplementation in women of childbearing age for the prevention of neural tube defects in infants. The current review assessed new evidence on the benefits and harms of folic acid supplementation. Findings: The USPSTF assessed the balance of the benefits and harms of folic acid supplementation in women of childbearing age and determined that the net benefit is substantial. Evidence is adequate that the harms to the mother or infant from folic acid supplementation taken at the usual doses are no greater than small. Therefore, the USPSTF reaffirms its 2009 recommendation. Conclusions and Recommendation: The USPSTF recommends that all women who are planning or capable of pregnancy take a daily supplement containing 0.4 to 0.8 mg (400-800 µg) of folic acid. (A recommendation).

BACKGROUND: Obesity is associated with poor asthma control, increased asthma morbidity, and decreased response to inhaled corticosteroids. We hypothesized that obesity would be associated with decreased bronchodilator responsiveness in children and adolescents with asthma. In addition, we hypothesized that subjects who were obese and unresponsive to bronchodilator would have worse asthma control and would require more asthma controller medications. METHODS: In the Study of African Americans, Asthma, Genes, and Environments (SAGE II) and the Genes-environments and Admixture in Latino Americans (GALA II) study, two identical, parallel, case-control studies of asthma, we examined the association between obesity and bronchodilator response in 2,963 black and Latino subjects enrolled from 2008 to 2013 using multivariable logistic regression. Using bronchodilator responsiveness, we compared asthma symptoms, controller medication usage, and asthma exacerbations between nonobese (< 95th% BMI) and obese (≥ 95th% BMI) subjects. RESULTS: The odds of being bronchodilator unresponsive were 24% (OR, 1.24; 95% CI, 1.03-1.49) higher among obese children and adolescents compared with their not obese counterparts after adjustment for age, race/ethnicity, sex, recruitment site, baseline lung function (FEV1/FVC), and controller medication. Bronchodilator-unresponsive obese subjects were more likely to report wheezing (OR, 1.38; 95% CI, 1.13-1.70), being awakened at night (OR, 1.34; 95% CI, 1.09-1.65), using leukotriene receptor inhibitors (OR, 1.33; 95% CI, 1.05-1.70), and using inhaled corticosteroid with long-acting ß2-agonist (OR, 1.37; 95% CI, 1.05-1.78) than were their nonobese counterpart. These associations were not seen in the bronchodilator-responsive group. CONCLUSIONS: Obesity is associated with bronchodilator unresponsiveness among black and Latino children and adolescents with asthma. The findings on obesity and bronchodilator unresponsiveness represent a unique opportunity to identify factors affecting asthma control in blacks and Latinos.
