“…Hypertension and acute respiratory infections dominated CVD and respiratory emergency visits. Hypertension is a risk factor for stroke and heart disease (O’Donnell et al, 2010); for both of them, Arkansas has one of the highest mortality and incidence rates in the nation, with Blacks/African Americans having higher risks than whites (Reeve et al, 2012). The increasing trend of CVD emergency visits over the 2002–2012 period may be contributed to earlier diagnoses of specific risk factors (eg, hypertension) and subsequent treatment, which, in turn, may have contributed to the declining trends of mortality (Crimmins and Beltran-Sanchez, 2014; Koton et al, 2014).…”

Background Heart disease and stroke mortality and morbidity rates in Arkansas are among the highest in the U.S. While the effect of air pollution on cardiovascular health was identified in traffic-dominated metropolitan areas, there is a lack of studies for populations with variable exposure profiles, demographic and disease characteristics. Objective Determine the short-term effects of air pollution on cardiovascular and respiratory morbidity in the stroke and heart failure belt. Methods We investigated the associations of fine particles and ozone with respiratory and cardiovascular emergency room visits during the 2002–2012 period for adults in Central Arkansas using Poisson generalized models adjusted for temporal, seasonal and meteorological effects. We evaluated sensitivity of the associations to mutual pollutant adjustment and effect modification patterns by sex, age, race and season. Results We found effects on cardiovascular and respiratory emergencies for PM2.5 (1.52% [95%CI: −1.10, 4.20]; 1.45% [95%CI: −2.64, 5.72] per 10 μg/m3) and O3 (0.93% [95%CI: −0.87, 2.76]; 0.76 [95%CI: −1.92, 3.52] per 10 ppbv) during the cold period (October–March). The effects were stronger among whites, except for the respiratory effects of O3 that were higher among Blacks/African-Americans. Effect modification patterns by age and sex differed by association. Both pollutants were associated with increases in emergency room visits for hypertension, heart failure and asthma. Effects on cardiovascular and respiratory emergencies were observed during the cold period when particulate matter was dominated by secondary nitrate and wood burning. Conclusion Outdoor particulate pollution during winter had an effect of cardiovascular morbidity in central Arkansas, the region with high stroke and heart disease incidence rates.

“…Based on an approach suggested in The Lancet, 20,21 we conducted a post hoc meta-analysis, in which the findings of the current trial were combined meta-analytically with the three other randomized studies in noncardiac and nonthoracic surgical populations that have incorporated BIS-guided care as an intervention and have evaluated postoperative delirium as the primary outcome. 6-8 A DerSimonian-Laird random effects meta-analysis was conducted using the R statistical environment (R Foundation for Statistical Computing, Vienna, Austria).…”

“…As SRs are used more and rated more highly by health professionals in terms of relevance to clinical practice than original articles on primary research with other designs, it is inefficient that they are not easily recognizable. 35,36 Because impact factors of rehabilitation journals are often smaller compared with other medical journals, most reviews were published in journals with impact factors less than 5. Nevertheless, 15 SRs (17%) were published in journals with moderate to high impact factors (5.1-10.0), in which we might assume a highly selective peer-review process, including Cochrane reviews.…”
