ABSTRACTObjectives Because African Americans are at elevated risk for cognitive decline and Alzheimer's disease, it is important to understand which health and lifestyle factors are most important for reducing this risk. Obesity and poor sleep quality are common in lower-income, urban African Americans and have been linked to cognitive decline in older age. Fortunately, increasing aerobic fitness via regular exercise can improve cognitive function. This study sought to (1) examine the cross-sectional relationship between aerobic fitness and cognitive function in older African Americans, and (2) determine whether body mass index and sleep quality moderated the relationship between aerobic fitness and cognition. Design 402 older African Americans, ages 60-90 (84% female, mean education level = 14 years) completed neuropsychological testing, computerized behavioral tasks, physical performance measures, and health and lifestyle questionnaires. Hierarchical linear regressions were performed to determine associatioder social and environmental context.Objective To compare the effects of hyaluronic acid (HA) and dextrose prolotherapy (DPT) injections in patients with chronic lateral epicondylalgia (LE). Materials and Methods Thirty-two patients with at least 6 months of signs and symptoms of LE were randomly allocated into two groups an HA group (n = 16) and a DPT group (n = 16). HA injection was performed as a single dose of 30 mg/2 mL 1500 kDa high-molecular-weight preparation (baseline). DPT injection was administered with 15% dextrose solution in three doses (baseline, third week, and sixth week). Severity of pain using the visual analog scale score, grip strength with a hand dynamometer, and physical function as determined by the Quick-Disabilities of the Arm, Shoulder, and Hand (Q-DASH) score were determined. Results DPT was favored over HA for improvements from 0 to 12 weeks for pain with activity (4.81 ± 1.2 vs. 3.18 ± 2.3; p = 0.04), pain at night (5.1 ± 1.9 vs. 4.1 ± 2.2; p = 0.03), and pain at rest (3.8 ± 2.09 vs. 2.7 ± 1.7; p = 0.04). Q-DASH scores improved significantly more from 0 to 12 weeks in the DPT group (43.5 ± 17.6 vs. 28.4 ± 13.4; p = 0.04). No between-group improvement was observed for grip pain (7.3 ± 6.4 vs. 4.8 ± 3.2; p = 0.38). Conclusions HA and DPT injections were both effective in reducing pain and increasing grip strength and function in patients with chronic LE. DPT injection was more effective in the short term than HA injection, in terms of pain relief and functional outcome. The study was registered at ClinicalTrials.gov under the identifier number NCT04395417.
Sequence variation at chromosome 9p21.3 accounts for 20% of myocardial infarctions (MIs) in several populations. Whereas the risk conferred by the 9p21.3 locus appears to act independently of traditional risk factors, studies suggest that the association between 9p21.3 and MI is modified by glucose homeostasis and lifestyle. We examined if the 9p21.3 variant rs1333049, along with the previously identified predictor fasting insulin, modifies the preventive effect of bariatric surgery on MI incidence.

rs1333049 was genotyped in 1852 patients treated by bariatric surgery and 1803 controls given usual care in the SOS study (Swedish Obese Subjects). MI incidence was determined using national registers. Median follow-up was 21 years (interquartile range 18-24 years).

Overall, 366 MIs occurred during follow-up. Among rs1333049 risk-allele carriers (CC+GC), the incidence of MI was reduced in the surgery group compared with the control group (hazard ratio=0.72 [95% CI, 0.57-0.92],
=0.008). selleck inhibitor By contrast, noncarriers (GG) showed no significant differences in MI incidence between the treatment groups (hazard ratio=1.28 [0.86-1.90],
=0.227; interaction between treatment and the risk-allele
=0.016). In addition, carriers with higher fasting insulin (above the median [17 mmol/L]) experienced significantly higher MI incidence than carriers with lower fasting insulin (hazard ratio=0.58 [0.42-0.78],
<0.001, interaction
=0.031).

In the SOS cohort, patients with the chromosome 9p21.3 rs1333049 risk allele together with high fasting insulin levels benefitted from bariatric surgery in terms of reduced incidence of MI. Registration URL https//www.clinicaltrials.gov. Unique identifier NCT01479452.

Racial and socioeconomic disparities in health access and outcomes for many conditions is well known. However, for time-sensitive high-acuity diseases such as traumatic injuries, disparities in access and outcomes should be significantly diminished. Our primary objective was to characterize racial disparities across majority, mixed-race, and minority hospitals for African American ([AA] vs White) males with high-grade splenic injuries.

Data from the National Trauma Data Bank were utilized from 2007 to 2015; 24 855 AA or White males with high-grade splenic injuries were included. Multilevel mixed-effects regression analysis was used to evaluate disparities in outcomes and resource allocation.

Mortality was significantly higher for AA males at mixed-race (OR 1.6; 95% CI 1.3-2.1;
< .001) and minority (OR 2.1; 95% CI 1.5-3.0;
< .001) hospitals, but not at majority hospitals. At minority hospitals, AA males were significantly less likely to be admitted to the intensive care unit (OR 0.7; 95% CI, 0.49-0.97;
= .04) and experienced a significantly longer time to surgery (IRR 1.5;
= .02). Minority hospitals were significantly more likely to have failures from angiographic embolization requiring operative intervention (OR 2.2,
= .009). At both types of nonmajority hospitals, AA males with penetrating injuries were more likely to be managed with angiography (mixed-race hospitals OR 1.7;
= .046 vs minority hospitals OR 1.6;
= .08).

While multiple studies have shown that minority hospitals have increased mortality compared to majority hospitals, this study found this disparity only existed for AAs.
