RESUMO

Exposure to environmental tobacco smoke (ETS) is associated with increased risk of disease and death. Reports on ETS and religion are lacking. Data from the National Health and Nutrition Examination Survey were used to test this association. In 4,712 nonsmokers, serum cotinine level of 0.05-3.99 ng/mL indicated ETS exposure. Frequency of attendance at religious services was categorized as > = weekly or less. In bivariate analysis, ETS exposure occurred in 28.6% of those with > = weekly attendance but 36.4% of less frequent attenders (p = 0.0004). In logistic regression controlling for multiple confounders OR = 0.72, 95%CI 0.61-0.85. ETS exposure was negatively associated with religion.

RESUMO

AIMS: There is debate about the optimum algorithm for cardiovascular disease (CVD) risk estimation. We conducted head-to-head comparisons of four algorithms recommended by primary prevention guidelines, before and after 'recalibration', a method that adapts risk algorithms to take account of differences in the risk characteristics of the populations being studied. METHODS AND RESULTS: Using individual-participant data on 360 737 participants without CVD at baseline in 86 prospective studies from 22 countries, we compared the Framingham risk score (FRS), Systematic COronary Risk Evaluation (SCORE), pooled cohort equations (PCE), and Reynolds risk score (RRS). We calculated measures of risk discrimination and calibration, and modelled clinical implications of initiating statin therapy in people judged to be at 'high' 10 year CVD risk. Original risk algorithms were recalibrated using the risk factor profile and CVD incidence of target populations. The four algorithms had similar risk discrimination. Before recalibration, FRS, SCORE, and PCE over-predicted CVD risk on average by 10%, 52%, and 41%, respectively, whereas RRS under-predicted by 10%. Original versions of algorithms classified 29-39% of individuals aged ≥40 years as high risk. By contrast, recalibration reduced this proportion to 22-24% for every algorithm. We estimated that to prevent one CVD event, it would be necessary to initiate statin therapy in 44-51 such individuals using original algorithms, in contrast to 37-39 individuals with recalibrated algorithms. CONCLUSION: Before recalibration, the clinical performance of four widely used CVD risk algorithms varied substantially. By contrast, simple recalibration nearly equalized their performance and improved modelled targeting of preventive action to clinical need.

RESUMO

PURPOSE: There is presently an ongoing debate on the relative merits of suggested criteria for spirometric airway obstruction. This study tests the null hypothesis that no superiority exists with the use of fixed ratio (FR) of forced expiratory volume in the first second (FEV1)/forced vital capacity (FVC) < 0.7 versus less than lower limit predicted (LLN) criteria with or without FEV1 <80% predicted in regards to future mortality. METHODS: In 1988-1994 the Third National Health and Nutrition Examination Survey (NHANES III) measured FEV1 and FVC with mortality follow-up data through December 31, 2011. For this survival analysis 7472 persons aged 40 and over with complete data formed the analytic sample. RESULTS: There were a total of 3554 deaths. Weighted Cox proportional hazards regression revealed an increased hazard ratio in persons with both fixed ratio and lower limit of normal with a low FEV1 (1.79, p < 0.0001), in those with fixed ratio only with a low FEV1 (1.77, p < 0.0001), in those with abnormal fixed ratio only with a normal FEV1 (1.28, p < 0.0001) compared with persons with no airflow obstruction (reference group). These remained significant after adjusting for demographic variables and other confounding variables. CONCLUSIONS: The addition of FEV1 < 80% of predicted increased the prognostic power of the fixed ratio <0.7 and/or below the lower limit of predicted criteria for airway obstruction.

RESUMO

BACKGROUND: It is increasingly evident that high blood pressure can promote reduction in global and regional brain volumes. While these effects may preferentially affect the hippocampus, reports are inconsistent. METHODS: Using data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), we examined the relationships of hippocampal volume to pulse pressure (PPR) and systolic (SBP) and diastolic (DBP) blood pressure according to apolipoprotein (APOE) ɛ4 positivity and cognitive status. The ADNI data included 1,308 participants: Alzheimer disease (AD = 237), late mild cognitive impairment (LMCI = 454), early mild cognitive impairment (EMCI = 254), and cognitively normal (CN = 365), with up to 24 months of follow-up. RESULTS: Higher quartiles of PPR were significantly associated with lower hippocampal volumes (Q1 vs. Q4, p = 0.034) in the CN and AD groups, but with increasing hippocampal volume (Q1, p = 0.008; Q2, p = 0.020; Q3, p = 0.017; Q4 = reference) in the MCI groups. In adjusted stratified analyses among non-APOE ɛ4 carriers, the effects in the CN (Q1 vs. Q4, p = 0.006) and EMCI groups (Q1, p = 0.002; Q2, p = 0.013; Q3, p = 0.002; Q4 = reference) remained statistically significant. Also, higher DBP was significantly associated with higher hippocampal volume (p = 0.002) while higher SBP was significantly associated with decreasing hippocampal volume in the EMCI group (p = 0.015). CONCLUSION: Changes in PPR, SBP, and DBP differentially influenced hippocampal volumes depending on the cognitive and APOE genotypic categories.

RESUMO

Chronic obstructive pulmonary disease (COPD) mortality based on the underlying cause of death (UCOD) underestimates disease burden. We aimed to determine the current COPD mortality rate, trends and the distribution of co-morbidities using United States (US) multiple-cause of death (MCOD) records. All 38,905,575 death certificates of decedents aged ≥45 years in the United States were analyzed for 1999-2015. COPD was defined by ICD-10 codes J40-J44 and J47 based either on the UCOD or up to 20 contributing causes coded. Annual age-standardized COPD death rates were computed by age, gender and race/ethnicity for those with any mention of COPD. In 2015, COPD was mentioned in 11.59% (292,572 deaths) in MCOD, compared to 11.13% (243,617 deaths) in 1999, a 4% increase. However, it was reported as the UCOD for only 5.56% and 4.97% in 2015 and 1999 respectively, an 11% increase. The most common UCOD in subjects with any mention of COPD was respiratory disorders in 49% of males and 55% of females. The relative change in death rates differed between MCOD and UCOD. For example, among non-Hispanic white females aged 65-74 years the UCOD rate per 100,000 (95% CI) decreased from 163 (160-166) to 147 (145-150), average annual percent decrease (AAPD) -0.26, while the MCOD rate decreased from 308 (304-311) to 263 (260-267), AAPD -0.87. Statistics based on UCOD understated the burden of COPD in the United States. MCOD rates were twice as high as UCOD rates. The relative change in death percent or rates differed between MCOD and UCOD. MCOD analysis should be repeated periodically to help evaluate the burden of COPD-related mortality.

RESUMO

BACKGROUND: The burden of stroke in low- and middle-income countries (LMICs) is large and increasing, challenging the already stretched health-care services. AIMS AND OBJECTIVES: To determine the quality of existing stroke-care services in LMICs and to highlight indigenous, inexpensive, evidence-based implementable strategies being used in stroke-care. METHODS: A detailed literature search was undertaken using PubMed and Google scholar from January 1966 to October 2015 using a range of search terms. Of 921 publications, 373 papers were shortlisted and 31 articles on existing stroke-services were included. RESULTS: We identified efficient models of ambulance transport and pre-notification. Stroke Units (SU) are available in some countries, but are relatively sparse and mostly provided by the private sector. Very few patients were thrombolysed; this could be increased with telemedicine and governmental subsidies. Adherence to secondary preventive drugs is affected by limited availability and affordability, emphasizing the importance of primary prevention. Training of paramedics, care-givers and nurses in post-stroke care is feasible. CONCLUSION: In this systematic review, we found several reports on evidence-based implementable stroke services in LMICs. Some strategies are economic, feasible and reproducible but remain untested. Data on their outcomes and sustainability is limited. Further research on implementation of locally and regionally adapted stroke-services and cost-effective secondary prevention programs should be a priority.

RESUMO

Few studies have examined the relationship between television viewing, computer use, and sleep symptoms. We hypothesized that television and computer time was associated with sleep symptoms. Screen hours were the sum of daily TV hours and computer hours. A total of 4342 participants 20 years and older had data on screen hours. After adjusting for confounders, 4 or more screen hours were significantly associated with increased odds of reporting long sleep latency, nighttime awakening, high sleep hours, and snoring (P < .05). These findings suggest that increased screen/TV time is an important risk factor for sleep symptoms.

RESUMO

PURPOSE: New onset supraventricular arrhythmias (SVA) are commonly reported in mixed intensive care settings. We sought to determine the incidence, risk factors and outcomes of new onset SVA in African American (AA) patients with severe sepsis admitted to medical intensive care unit (MICU). METHODS: Patients admitted to MICU between January 2012 through December 2012 were studied. Patients with a previous history of arrhythmia or with new onset of ventricular arrhythmia were excluded. Data on risk factors, critical care interventions and outcomes were obtained. RESULTS: One hundred and thirty-one patients were identified. New onset SVA occurred in 34 (26%) patients. Of those 34, 20 (59%) had atrial fibrillation (AF), 6 (18%) had atrial flutter and 8 (24%) had other forms of SVA. Compared with patients without SVA, patients with new onset SVA were older (69 ± 12 yrs vs 59 ± 13 yrs, P=.003), had congestive heart failure (47% vs 24%, P=.015) and dyslipidemia (41% vs 15%, P=.002). Additionally, they had a higher mean mortality prediction model (MPM II) score (65 ± 25 vs 49 ± 26, P=.001) and an increased incidence of respiratory failure (85% vs 55%, P=.001). Hospital mortality in patients with new onset SVA was 18 (53%) vs 30 (31%); P=.024; however, in a multivariate analysis, new onset SVA was associated with non-significantly increased odds (OR 2.58, 95% CI 0.86-8.05) for in-hospital mortality. CONCLUSIONS: New onset SVA was prevalent in AA patients with severe sepsis and occurred more frequently with advanced age, increased severity of illness, congestive heart failure, and acute respiratory failure; it was associated with higher unadjusted in hospital mortality. However, after multiple adjustments, new onset SVA did not remain an independent predictor of mortality.

RESUMO

INTRODUCTION: This book review analyzes the complex and profound impact active religious participation has on relationships and family outcomes among African Americans and Latinos. In Soul Mates, Wilcox and Wolfinger discuss the legacy of slavery and Jim Crow laws and the resulting devastating effects on African American and Latino families despite their high religious involvement. The authors make the case that many African American men are unlikely candidates for marriage or stable relationships due to trends of family instability driven by the declining income-power of working-class men as well as entry of more women into the labor force, government penalties for low-income couples, revolt against traditional values, increased access to birth control and abortion, and the persistence of discrimination and incarceration of minority men. METHODS: The authors examine data from six national surveys as well as additional data from interviews, focus groups, ethnographic field work, and an extensive literature review. RESULTS: Wilcox and Wolfinger find evidence that when African American couples actively participate in Christian churches, the men are more likely to adhere to a "code of decency" which decreases street behaviors, such as binge drinking, having multiple sex partners, and having multi-partner fertility, which are known to inhibit family stability. CONCLUSIONS: This book will be helpful for health providers who would like to better understand and serve their African American and Latino patients. The findings suggest that health care providers can promote a healthy emotional environment for families by encouraging minority men to renew or maintain church involvement.

RESUMO

BACKGROUND: The global burden of atrial fibrillation (AF) is unknown. METHODS AND RESULTS: We systematically reviewed population-based studies of AF published from 1980 to 2010 from the 21 Global Burden of Disease regions to estimate global/regional prevalence, incidence, and morbidity and mortality related to AF (DisModMR software). Of 377 potential studies identified, 184 met prespecified eligibility criteria. The estimated number of individuals with AF globally in 2010 was 33.5 million (20.9 million men [95% uncertainty interval (UI), 19.5-22.2 million] and 12.6 million women [95% UI, 12.0-13.7 million]). Burden associated with AF, measured as disability-adjusted life-years, increased by 18.8% (95% UI, 15.8-19.3) in men and 18.9% (95% UI, 15.8-23.5) in women from 1990 to 2010. In 1990, the estimated age-adjusted prevalence rates of AF (per 100 000 population) were 569.5 in men (95% UI, 532.8-612.7) and 359.9 in women (95% UI, 334.7-392.6); the estimated age-adjusted incidence rates were 60.7 per 100 000 person-years in men (95% UI, 49.2-78.5) and 43.8 in women (95% UI, 35.9-55.0). In 2010, the prevalence rates increased to 596.2 (95% UI, 558.4-636.7) in men and 373.1 (95% UI, 347.9-402.2) in women; the incidence rates increased to 77.5 (95% UI, 65.2-95.4) in men and 59.5 (95% UI, 49.9-74.9) in women. Mortality associated with AF was higher in women and increased by 2-fold (95% UI, 2.0-2.2) and 1.9-fold (95% UI, 1.8-2.0) in men and women, respectively, from 1990 to 2010. There was evidence of significant regional heterogeneity in AF estimations and availability of population-based data. CONCLUSIONS: These findings provide evidence of progressive increases in overall burden, incidence, prevalence, and AF-associated mortality between 1990 and 2010, with significant public health implications. Systematic, regional surveillance of AF is required to better direct prevention and treatment strategies.

RESUMO

BACKGROUND: There is debate about the value of assessing levels of C-reactive protein (CRP) and other biomarkers of inflammation for the prediction of first cardiovascular events. METHODS: We analyzed data from 52 prospective studies that included 246,669 participants without a history of cardiovascular disease to investigate the value of adding CRP or fibrinogen levels to conventional risk factors for the prediction of cardiovascular risk. We calculated measures of discrimination and reclassification during follow-up and modeled the clinical implications of initiation of statin therapy after the assessment of CRP or fibrinogen. RESULTS: The addition of information on high-density lipoprotein cholesterol to a prognostic model for cardiovascular disease that included age, sex, smoking status, blood pressure, history of diabetes, and total cholesterol level increased the C-index, a measure of risk discrimination, by 0.0050. The further addition to this model of information on CRP or fibrinogen increased the C-index by 0.0039 and 0.0027, respectively (P<0.001), and yielded a net reclassification improvement of 1.52% and 0.83%, respectively, for the predicted 10-year risk categories of "low" (<10%), "intermediate" (10% to <20%), and "high" (≥20%) (P<0.02 for both comparisons). We estimated that among 100,000 adults 40 years of age or older, 15,025 persons would initially be classified as being at intermediate risk for a cardiovascular event if conventional risk factors alone were used to calculate risk. Assuming that statin therapy would be initiated in accordance with Adult Treatment Panel III guidelines (i.e., for persons with a predicted risk of ≥20% and for those with certain other risk factors, such as diabetes, irrespective of their 10-year predicted risk), additional targeted assessment of CRP or fibrinogen levels in the 13,199 remaining participants at intermediate risk could help prevent approximately 30 additional cardiovascular events over the course of 10 years. CONCLUSIONS: In a study of people without known cardiovascular disease, we estimated that under current treatment guidelines, assessment of the CRP or fibrinogen level in people at intermediate risk for a cardiovascular event could help prevent one additional event over a period of 10 years for every 400 to 500 people screened.

RESUMO

BACKGROUND: Asthma mortality and morbidity are higher in black than in white children. Fractional exhaled nitric oxide (FeNO) is a noninvasive biomarker of eosinophilic airway inflammation. Identification of differences in the effect of environmental tobacco smoke (ETS) on airway inflammation by race and ethnicity from a large sample is needed. OBJECTIVE: To estimate a racial difference in association with ETS and FeNO. METHODS: Data from the 2007 to 2012 National Health and Nutrition Examination Survey were analyzed to compare associations of ETS and FeNO levels in US black and other children. No ETS exposure was defined as a serum cotinine level lower than 0.05 ng/mL and ETS exposure was defined as a serum cotinine level of at least 0.05 ng/mL. FeNO was measured using a device that relies on an electrochemical sensor. Analyses took the complex survey design into account. RESULTS: The analytic sample was formed by 5,473 participants (6-11 years old, n = 2,385; 12-19 years old, n = 3,088) with complete data on demographics, serum cotinine levels, and 2 reproducible FeNO measurements. In weighted linear regression analyses at 6 to 11 years, the interaction term for ETS and black race was not significant (P = .15). At 12 to 19 years, the interaction term was significant (P = .03) in an analysis of all racial groups. In race-specific models, the coefficient for ETS exposure in blacks was -0.033 and that in others was -0.175, ie, ETS exposure was associated with a greater decrease in FeNO in non-blacks than in blacks. CONCLUSION: There was no evidence at 6 to 11 years of age for an effect modification by race of the association between ETS and FeNO. At 12 to 19 years, the data suggested an effect modification.

RESUMO

IMPORTANCE: The prevalence of cardiometabolic multimorbidity is increasing. OBJECTIVE: To estimate reductions in life expectancy associated with cardiometabolic multimorbidity. DESIGN, SETTING, AND PARTICIPANTS: Age- and sex-adjusted mortality rates and hazard ratios (HRs) were calculated using individual participant data from the Emerging Risk Factors Collaboration (689,300 participants; 91 cohorts; years of baseline surveys: 1960-2007; latest mortality follow-up: April 2013; 128,843 deaths). The HRs from the Emerging Risk Factors Collaboration were compared with those from the UK Biobank (499,808 participants; years of baseline surveys: 2006-2010; latest mortality follow-up: November 2013; 7995 deaths). Cumulative survival was estimated by applying calculated age-specific HRs for mortality to contemporary US age-specific death rates. EXPOSURES: A history of 2 or more of the following: diabetes mellitus, stroke, myocardial infarction (MI). MAIN OUTCOMES AND MEASURES: All-cause mortality and estimated reductions in life expectancy. RESULTS: In participants in the Emerging Risk Factors Collaboration without a history of diabetes, stroke, or MI at baseline (reference group), the all-cause mortality rate adjusted to the age of 60 years was 6.8 per 1000 person-years. Mortality rates per 1000 person-years were 15.6 in participants with a history of diabetes, 16.1 in those with stroke, 16.8 in those with MI, 32.0 in those with both diabetes and MI, 32.5 in those with both diabetes and stroke, 32.8 in those with both stroke and MI, and 59.5 in those with diabetes, stroke, and MI. Compared with the reference group, the HRs for all-cause mortality were 1.9 (95% CI, 1.8-2.0) in participants with a history of diabetes, 2.1 (95% CI, 2.0-2.2) in those with stroke, 2.0 (95% CI, 1.9-2.2) in those with MI, 3.7 (95% CI, 3.3-4.1) in those with both diabetes and MI, 3.8 (95% CI, 3.5-4.2) in those with both diabetes and stroke, 3.5 (95% CI, 3.1-4.0) in those with both stroke and MI, and 6.9 (95% CI, 5.7-8.3) in those with diabetes, stroke, and MI. The HRs from the Emerging Risk Factors Collaboration were similar to those from the more recently recruited UK Biobank. The HRs were little changed after further adjustment for markers of established intermediate pathways (eg, levels of lipids and blood pressure) and lifestyle factors (eg, smoking, diet). At the age of 60 years, a history of any 2 of these conditions was associated with 12 years of reduced life expectancy and a history of all 3 of these conditions was associated with 15 years of reduced life expectancy. CONCLUSIONS AND RELEVANCE: Mortality associated with a history of diabetes, stroke, or MI was similar for each condition. Because any combination of these conditions was associated with multiplicative mortality risk, life expectancy was substantially lower in people with multimorbidity.

RESUMO

BACKGROUND: The extent to which diabetes mellitus or hyperglycemia is related to risk of death from cancer or other nonvascular conditions is uncertain. METHODS: We calculated hazard ratios for cause-specific death, according to baseline diabetes status or fasting glucose level, from individual-participant data on 123,205 deaths among 820,900 people in 97 prospective studies. RESULTS: After adjustment for age, sex, smoking status, and body-mass index, hazard ratios among persons with diabetes as compared with persons without diabetes were as follows: 1.80 (95% confidence interval [CI], 1.71 to 1.90) for death from any cause, 1.25 (95% CI, 1.19 to 1.31) for death from cancer, 2.32 (95% CI, 2.11 to 2.56) for death from vascular causes, and 1.73 (95% CI, 1.62 to 1.85) for death from other causes. Diabetes (vs. no diabetes) was moderately associated with death from cancers of the liver, pancreas, ovary, colorectum, lung, bladder, and breast. Aside from cancer and vascular disease, diabetes (vs. no diabetes) was also associated with death from renal disease, liver disease, pneumonia and other infectious diseases, mental disorders, nonhepatic digestive diseases, external causes, intentional self-harm, nervous-system disorders, and chronic obstructive pulmonary disease. Hazard ratios were appreciably reduced after further adjustment for glycemia measures, but not after adjustment for systolic blood pressure, lipid levels, inflammation or renal markers. Fasting glucose levels exceeding 100 mg per deciliter (5.6 mmol per liter), but not levels of 70 to 100 mg per deciliter (3.9 to 5.6 mmol per liter), were associated with death. A 50-year-old with diabetes died, on average, 6 years earlier than a counterpart without diabetes, with about 40% of the difference in survival attributable to excess nonvascular deaths. CONCLUSIONS: In addition to vascular disease, diabetes is associated with substantial premature death from several cancers, infectious diseases, external causes, intentional self-harm, and degenerative disorders, independent of several major risk factors.

RESUMO

Is there a full-blown stroke epidemic and a growing ischemic heart disease (IHD) epidemic in Sub-Saharan Africa? We aim to further understand the evolution of stroke and IHD in Sub-Saharan Africa with an analysis of the most recent Global Burden of Disease estimates of mortality for men of Sub-Saharan African descent in Africa and in the Caribbean and a review of recent studies found on PubMed and reference lists of published articles. Stroke is the most important cause of cardiovascular disease mortality in men aged 60-64 years in Africa and the Caribbean, but death rates and rank may vary by region. Ischemic heart disease is a leading cause in the Caribbean.

RESUMO

Smoking and gender are known risk factors for sleep disorders. Studies of samples from Norway and Japan have suggested stronger associations between smoking and disrupted sleep in women; therefore, we examined, gender differences in the association in the U.S. population. We analyzed data from the 2005-2006 National Health and Nutrition Examination Survey. We examined the associations between smoking and self-reported measures of sleep disorders (i.e., snoring, short sleep, long sleep, poor sleep, and health care provider diagnosis of sleep disordered breathing) using multivariate logistic regression with odds ratios (OR) and 95% confidence intervals (CI) as measures of association. We also assessed whether the associations varied by gender using a gender x smoking interaction term. Compared to never smokers, current smokers had significantly higher odds of self-reported snoring (OR = 2.0; 95% CI = 1.56-2.56), short sleep (OR 1.68; 95% CI = 1.35-2.10) and poor sleep (OR = 1.38; 95% CI = 1.09-1.74). A dose-response relationship was observed between the amount smoked and sleep symptoms. In multivariate analyses, no significant gender x smoking interaction was observed for snoring, short sleep or poor sleep. Current smoking was independently associated with increased odds of snoring, short sleep, and poor sleep in women and men among U.S. adults.

RESUMO

BACKGROUND: Social variables are correlates of mortality. A number of social variables were used by the Centers for Disease Control and Prevention (CDC) to create a Social Vulnerability Index (SVI). SVI has been used as a correlate of health status. Age-adjusted mortality rates have been higher in Mississippi than in other states. Within Mississippi, the Delta region has had higher mortality. To test the hypothesis that social vulnerability was associated with mortality rate within the state, we examined SVI of counties in Mississippi as related to mortality from all causes in 2016-2020. METHODS: The CDC/ATSDR SVI ranks each census tract on 16 social factors, including poverty, lack of vehicle access, and crowded housing, and groups them into four related themes. Using CDC Wonder, we gathered data analyzing age-adjusted rate of death from all causes (AAR) in Mississippi Counties from 2016 to 2020, combined (reporting the death rate per 100,000 persons). Descriptive statistics were computed for each variable. Pearson correlation analysis, bivariable and multivariable regression analysis was done using Microsoft Excel version 16.77. The dependent variable was AAR and independent variables were for themes from the SVI. RESULTS: AAR varied greatly amongst counties in Mississippi. Higher AAR was seen in northwestern areas of Mississippi. The county with the lowest AAR (730 per 100,000 persons) had only half the AAR of the county with the highest AAR (1313.3 per 100,000 persons). The association of SVI THEME 1 (socioeconomic status) with AAR in Mississippi was positive. Linear regression analysis showed a coefficient of 203.5, 95 % CI 111.9-295.0, p = 0. 0.0000305. R square was 0.20. The addition of the following themes added little to the variation in AAR explained: SVI THEME 2 (household characteristics), SVI THEME 3 (racial and ethnic minority status), and SVI THEME 4 (housing type/transportation). CONCLUSION: Socioeconomic status explained a fifth of the variation in AAR among Mississippi counties in 2016-2020.

RESUMO

BACKGROUND: Persistent inflammation has been proposed to contribute to various stages in the pathogenesis of cardiovascular disease. Interleukin-6 receptor (IL6R) signalling propagates downstream inflammation cascades. To assess whether this pathway is causally relevant to coronary heart disease, we studied a functional genetic variant known to affect IL6R signalling. METHODS: In a collaborative meta-analysis, we studied Asp358Ala (rs2228145) in IL6R in relation to a panel of conventional risk factors and inflammation biomarkers in 125,222 participants. We also compared the frequency of Asp358Ala in 51,441 patients with coronary heart disease and in 136,226 controls. To gain insight into possible mechanisms, we assessed Asp358Ala in relation to localised gene expression and to postlipopolysaccharide stimulation of interleukin 6. FINDINGS: The minor allele frequency of Asp358Ala was 39%. Asp358Ala was not associated with lipid concentrations, blood pressure, adiposity, dysglycaemia, or smoking (p value for association per minor allele ≥0·04 for each). By contrast, for every copy of 358Ala inherited, mean concentration of IL6R increased by 34·3% (95% CI 30·4-38·2) and of interleukin 6 by 14·6% (10·7-18·4), and mean concentration of C-reactive protein was reduced by 7·5% (5·9-9·1) and of fibrinogen by 1·0% (0·7-1·3). For every copy of 358Ala inherited, risk of coronary heart disease was reduced by 3·4% (1·8-5·0). Asp358Ala was not related to IL6R mRNA levels or interleukin-6 production in monocytes. INTERPRETATION: Large-scale human genetic and biomarker data are consistent with a causal association between IL6R-related pathways and coronary heart disease.

RESUMO

BACKGROUND: In the US, little is known about aspirin use as a preventive measure for cardiovascular disease by immigration status. METHODS: Combined data from the National Health and Nutrition Examination Survey (NHANES) 2015-2016 and 2017- March 2020 (pre-pandemic data) were analyzed. Persons were asked about demographics including country of birth and those aged 40 years and older were asked about current use of aspirin to prevent cardiovascular disease (CVD). RESULTS: Among 2,321 born in the US, preventive aspirin use was significantly more prevalent (39.6%) than among 910 others (27.5%, p < 0.01). However, after stratifying by race/ethnicity and history of CVD, the difference was significant only in Hispanics with CVD. In logistic regression analyses in Hispanics controlling for age, gender and education, the US born had significantly higher odds of aspirin use in those with or without CVD. DISCUSSION: Among US Hispanics, use of aspirin for prevention of CVD was more prevalent in those born in the US than in others.
