Black heart transplant recipients have a higher mortality rate than white recipients 6–12 months after transplant. Whether there are racial disparities in post-transplant stroke incidence and all-cause mortality following post-transplant stroke among cardiac transplant recipients is unknown. Using a nationwide transplant registry, we assessed the association between race and incident post-transplant stroke using logistic regression and the association between race and mortality among adults who survived a post-transplant stroke using Cox proportional hazards regression. We found no evidence of an association between race and the odds of post-transplant stroke (OR = 1.00, 95% CI: 0.83–1.20). The median survival time of those with a post-transplant stroke in this cohort was 4.1 years (95% CI: 3.0, 5.4). There were 726 deaths among the 1139 patients with post-transplant stroke, including 127 deaths among 203 Black patients and 599 deaths among 936 white patients. Among post-transplant stroke survivors, Black transplant recipients experienced a 23% higher rate of mortality compared to white recipients (HR = 1.23, 95% CI: 1.00–1.52). This disparity is strongest in the period beyond the first 6 months and appears to be mediated by differences in the post-transplant setting of care between Black and white patients. The racial disparity in mortality outcomes was not evident in the past decade. The improved survival of Black patients in the recent decade may reflect overall protocol improvements for heart transplant recipients irrespective of race, such as advancements in surgical techniques and immediate postoperative care as well as increased awareness about reducing racial disparities.

To evaluate the association between interpregnancy interval (IPI) and risk for gestational diabetes mellitus (GDM). We conducted a retrospective cohort study among singleton, non-anomalous, live birth pregnancies of 5,705,812 pregnant individuals in the United States from 2016 to 2018. We examined IPI of 4–<6 months, 6–11 months, 12–17 months, 24–35 months, 36–47 months, 48–59 months, 60–71 months, and ≥72 months in comparison to the reference interval of 18–23 months in relation to risk for GDM. We used logistic regression to evaluate the association between IPI and risk for GDM. There is a significantly increased risk for GDM associated with IPIs of 6–11 months and 12–17 months compared to the reference of 18–23 months (adjusted Odds Ratio [aOR] 1.05, 95% CI: 1.03–1.07; aOR 1.02, 95% CI: 1.01–1.03). The risk for GDM is greater for longer IPIs (36–47 months aOR 1.10, 95% CI: 1.05–1.08; 48–59 months aOR 1.11, 95% CI: 1.09–1.13; 60–71 months aOR 1.14, 95% CI: 1.12–1.16; ≥72 months aOR 1.31, 95% CI: 1.30–1.33). Our findings support the growing evidence that shorter and longer IPI increase the risk of GDM in pregnant individuals. Screening guidelines for detection of GDM may need to be re-evaluated and updated to include longer IPIs (≥36 months) as a risk factor for earlier screening prior to current recommendation of 24 weeks gestational age.

Background: Long-term exposure to ambient air pollution has been associated with impaired cognitive function and vascular disease in older adults, but little is known about these associations among people with concerns about memory loss.Objective: To examine associations between exposures to fine particulate matter and residential proximity to major roads and markers of small vessel disease.Methods: From 2004-2010, 236 participants in the Massachusetts Alzheimer's Disease Research Center Longitudinal Cohort participated in neuroimaging studies. Residential proximity to major roads and estimated 2003 residential annual average of fine particulate air pollution (PM2.5) were linked to measures of brain parenchymal fraction (BPF), white matter hyperintensities (WMH), and cerebral microbleeds. Associations were modeled using linear and logistic regression and adjusted for clinical and lifestyle factors.Results: In this population (median age [interquartile range] = 74 [12], 57% female) living in a region with median 2003 PM2.5 annual average below the current Environmental Protection Agency (EPA) standard, there were no associations between living closer to a major roadway or for a 2μg/m3 increment in PM2.5 and smaller BPF, greater WMH volume, or a higher odds of microbleeds. However, a 2μg/m3 increment in PM2.5 was associated with -0.19 (95% Confidence Interval (CI): -0.37, -0.005) lower natural log-transformed WMH volume. Other associations had wide confidence intervals.Conclusions: In this population, where median 2003 estimated PM2.5 levels were below the current EPA standard, we observed no pattern of association between residential proximity to major roads or 2003 average PM2.5 and greater burden of small vessel disease or neurodegeneration.

Background: The medical and recreational use of marijuana is now legal in some parts of the United States; the health effects are unknown. We aimed to evaluate associations between recent marijuana use and exhaled nitric oxide (eNO) and pulmonary function.Methods: We performed a cross-sectional study of 10,327 US adults participating in the National Health and Nutrition Examination Survey in the years 2007 to 2012. We examined associations between marijuana use and eNO, FEV1, FVC, the FEV1/FVC ratio, and forced expiratory flow (midexpiratory phase) (FEF25%-75%) by weighted linear regression.Results: In the study population, there were 4,797 never users, 4,084 past marijuana users, 555 participants who used marijuana 5 to 30 days before the examination, and 891 participants who used marijuana 0 to 4 days before the examination. Current marijuana use in the past 4 days was associated with 13% lower eNO (95% CI, -18% to 8%). FVC was higher in past users (75 mL; 95% CI, 38-112) and current users in the past 5 to 30 days (159 mL; 95% CI, 80-237) and in users within 0 to 4 days of the examination (204 mL; 95% CI, 139-270) compared with never users. All associations remained unchanged and statistically significant in sensitivity analyses excluding current and past tobacco users.Conclusions: Current marijuana use was associated with lower levels of eNO and higher FVC. The lower eNO in marijuana smokers suggests that short-term exposure to marijuana may, like tobacco, acutely affect the pulmonary vascular endothelium and impair airflow through the small airways.

We investigated associations between ambient air pollution and microvessel function measured by peripheral arterial tonometry between 2003 and 2008 in the Framingham Heart Study Offspring and Third Generation Cohorts. We measured particulate matter with aerodynamic diameter ≤2.5 µm (PM2.5), black carbon, sulfates, particle number, nitrogen oxides, and ozone by using fixed monitors, and we determined moving averages for 1–7 days preceding vascular testing. We examined associations between these exposures and hyperemic response to ischemia and baseline pulse amplitude, a measure of arterial tone (n = 2,369). Higher short-term exposure to air pollutants, including PM2.5, black carbon, and particle number was associated with higher baseline pulse amplitude. For example, higher 3-day average PM2.5 exposure was associated with 6.3% higher baseline pulse amplitude (95% confidence interval: 2.0, 10.9). However, there were no consistent associations between the air pollution exposures assessed and hyperemic response. Our findings in a community-based sample exposed to relatively low pollution levels suggest that short-term exposure to ambient particulate pollution is not associated with vasodilator response, but that particulate air pollution is associated with baseline pulse amplitude, suggesting potentially adverse alterations in baseline vascular tone or compliance.

The article discusses a study on whether levels of particle matter air pollution lower than the present U.S. National Ambient Air Quality Standards raise the risk of ischemic stroke. The research involved 1,705 Boston area patients with confirmed ischemic stroke and abstracted information at the time of the onset of symptom and clinical characteristics. Results revealed that exposure to particulate matter air pollution at levels deemed safe by the U.S. EPA increases the risk of ischemic stroke.

Background: Some herbal supplements may contain lead.Objective: To examine whether use of specific herbal dietary supplements during the last 30 days is associated with blood lead levels in US men and women.Design: Cross-sectional analysis.Study Population: NHANES participants from 1999-2004, a representative sample of the civilian non-institutionalized US population.Measurements: Lead was measured in blood. Associations between lead and self-reported supplement use were estimated using multivariable regression weighted to account for NHANES sampling. Herbal supplements investigated were those previously reported to contain high heavy metal content: Ayurvedic or traditional Chinese medicine herbs, echinacea, ginkgo, ginseng, St. John's wort, and "other" herbs (specifically, kava, valerian, black cohosh, bee pollen, and nettle).Main Results: Among 6,712 women > or =20 years, those using herbal supplements had lead levels that were 10% higher than non-users (95% CI 3%-17%, p = 0.005). Women using Ayurvedic or traditional Chinese medicine herbs, St. John's wort, and "other" herbs had lead levels 24% (95% CI 5%-45%, p = 0.01), 23% (95% CI 4%-46%), p = 0.02), and 21% (95% CI 2%-44%, p = 0.03) higher, respectively, than non-users. No significant associations were observed between herb use and lead levels among men (n = 6,095). Among reproductive-aged women (16-45 years), herbal supplement users had lead levels 20% higher than non-users (95% CI 5%-34%, p = 0.008). In contrast, garlic and other dietary supplements were not associated with higher lead levels.Conclusion: Use of specific herbal supplements is associated with higher blood lead levels among women. Our data suggest testing guidelines for herbal supplements and regulations limiting lead in supplements are needed. [ABSTRACT FROM AUTHOR]

Background: The effects of weather on West Nile virus (WNV) mosquito populations in the United States have been widely reported, but few studies assess their overall impact on transmission to humans. Objectives: We investigated meteorologic conditions associated with reported human WNV cases in the United States. Methods: We conducted a case-crossover study to assess 16,298 human WNV cases reported to the Centers for Disease Control and Prevention from 2001 to 2005. The primary outcome measures were the incidence rate ratio of disease occurrence associated with mean weekly maximum temperature, cumulative weekly temperature, mean weekly dew point temperature, cumulative weekly precipitation, and the presence of ⩾ 1 day of heavy rainfall (⩾ 50 mm) during the month prior to symptom onset. Results: Increasing weekly maximum temperature and weekly cumulative temperature were similarly and significantly associated with a 35-83% higher incidence of reported WNV infection over the next month. An increase in mean weekly dew point temperature was significantly associated with a 9-38% higher incidence over the subsequent 3 weeks. The presence of at least 1 day of heavy rainfall within a week was associated with a 29-66% higher incidence during the same week and over the subsequent 2 weeks. A 20-mm increase in cumulative weekly precipitation was significantly associated with a 4-8% increase in incidence of reported WNV infection over the subsequent 2 weeks. Conclusions: Warmer temperatures, elevated humidity, and heavy precipitation increased the rate of human WNV infection in the United States independent of season and each others' effects.

Background: Case fatality rates after acute myocardial infarction (MI) have decreased markedly over the last 3 decades. Some subgroups may have benefited more than others, but this hypothesis has not been evaluated in a large nationally representative cohort. Accordingly, we sought to assess long-term temporal trends in mortality after hospitalization for MI and to assess whether these trends differ by sex, race, or age in a cohort of elderly patients.Methods: We studied a cohort of 4.9 million Medicare beneficiaries >or=65 years hospitalized for MI between 1984 and 2003 and calculated the proportion that died inhospital, within 30 days, and within 1 year of hospitalization. We used multivariable risk models to estimate relative and absolute changes in case fatality rate according to race, sex, and age groups.Results: After adjustment for age, sex, and race, between 1984 and 2003, there was a 54.3% (95% CI 53.7%-54.8%), 39.7% (95% CI 39.1%-40.3%), and 23.0% (95% CI 22.5%-23.5%) reduction in the risk of inhospital, 30-day, and 1-year mortality, respectively. Relative and absolute reductions were greater in whites than in blacks, with the biggest differences observed for 1-year mortality. Small and inconsistent differences were seen by sex after stratifying by race. Patients aged >or=90 years experienced the smallest relative reductions in case fatality rates, with the biggest differences observed for 1-year mortality.Conclusions: Among US Medicare beneficiaries, short-term MI case fatality rates have decreased significantly in all groups, but more so among whites than blacks. Additional studies are needed to clarify the basis for these observations. [ABSTRACT FROM AUTHOR]

Background: Muscle effects are the most common reported adverse effects of 3-hydroxy-3-methylglutaryl coenzyme A inhibitors (statins). However, in placebo-controlled trials the incidence of muscle pain is most often similar for placebo and active control groups.Objective: We sought to evaluate whether statin use was associated with a higher prevalence of musculoskeletal pain in a nationally representative sample.Methods: Cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES) 1999-2002. Participants were 3,580 adults > or =40 years without arthritis who were interviewed at home and examined in a mobile examination center. Participants were asked about sociodemographic characteristics, health conditions, medication use, and musculoskeletal pain. Height, weight, blood pressure, ankle brachial index, and cholesterol were measured.Measurements and Main Results: Prevalence and adjusted odds ratios (OR) of any musculoskeletal pain and musculoskeletal pain in 4 different anatomical regions (neck/upper back, upper extremities, lower back, and lower extremities) by statin use during the last 30 days. Among statin users (n = 402), 22.0% (95%CI 18.0-26.7%) reported musculoskeletal pain in at least 1 anatomical region during the last 30 days, compared with 16.7% (95%CI 15.1-18.4%) of those who did not use a statin. Compared to persons who did not use statins, those who used statins had multivariable-adjusted odds ratios (95%CI; p value) of 1.50 (1.07-2.11; p = .01) for any musculoskeletal pain, 1.59 (1.04-2.44, p = .03) for lower back pain, and 1.50 (1.02-2.22, p = .03) for lower extremity pain.Conclusion: Musculoskeletal pain is common in adults > or =40 years without arthritis. In this nationally representative sample, statin users were significantly more likely to report musculoskeletal pain. [ABSTRACT FROM AUTHOR]

United States firefighters have a high on-duty fatality rate, and coronary heart disease is the leading cause. Seasonality affects the incidence of cardiovascular events in the general population, but its effects on firefighters are unknown. This study statistically examined the seasonal and annual variation of all on-duty coronary heart disease deaths among US firefighters between 1994 and 2004 using the chi-square distribution and Poisson regression model of the monthly fatality counts. It also examined the effect of ambient temperature (apparent as well as wind chill temperature) on coronary heart disease fatalities during the study span using a time-stratified, case-crossover study design. When grouped by season, we observed the distribution of the 449 coronary heart disease fatalities to show a relative peak in winter (32%) and relative nadir in spring (21%). This pattern was significantly different (p=0.005) from the expected distribution under the null hypothesis of season having no effect. The pattern persisted in additional analyses, stratifying the deaths by the type of duty in which the firefighters were engaged at the time of their deaths. In the Poisson regression model of the monthly fatality counts, the overall goodness-of-fit between the actual and predicted case counts was excellent (χ42=16.63; p=0.002). Two distinct peaks were detected: one in January-February and the other in August-September. Overall temperature was not associated with increased risk of on-duty death. After allowing for different effects of temperature in mild/hot versus cold periods, a 1°C increase was not protective in cold weather; nor did it increase the risk of death in warmer weather. The findings of this study reveal statistical evidence for excess coronary heart disease deaths among firefighters during winter; however, the temporal pattern of coronary heart disease deaths was not linked to temperature variation. The seasonal pattern was also found to be independent of duty-related risks. [ABSTRACT FROM AUTHOR]

BACKGROUND: Long-term exposure to particulate air pollution has been associated with an increased risk of dying from cardiopulmonary and ischemic heart disease, yet few studies have evaluated cardiovascular end points other than mortality. We investigated the relationship between long-term exposure to traffic and occurrence of acute myocardial infarction (AMI) in a case-control study. METHODS: A total of 5,049 confirmed cases of AMI were identified between 1995 and 2003 as part of the Worcester Heart Attack Study, a community-wide study examining changes over time in the incidence of AMI among greater Worcester, Massachusetts, residents. Population controls were selected from Massachusetts resident lists. We used cumulative traffic within 100 m of subjects' residence and distance from major roadway as proxies for exposure to traffic-related air pollution. We estimated the relationship between exposure to traffic and occurrence of AMI using logistic regression, and we adjusted for the following potential confounders: age, sex, section of the study area, point sources emissions of particulate matter with aerodynamic diameter < 2.5 µm, area socioeconomic characteristics, and percentage of open space. RESULTS: An increase in cumulative traffic near the home was associated with a 4% increase in the odds of AMI per interquartile range [95% confidence interval (CI), 2-7%], whereas living near a major roadway was associated with a 5% increase in the odds of AMI per kilometer (95% CI, 3-6%). CONCLUSIONS: These results provide support for an association between long-term exposure to traffic and the risk of AMI. [ABSTRACT FROM AUTHOR]

We determined the relationship of alcohol consumption and Medicare costs among 4,392 participants in the Cardiovascular Health Study (CHS), a longitudinal, population-based cohort study of adults age 65 or over in four U.S. communities. We assessed 5-year Parts A and B costs and self-reported intake of beer, wine, and liquor at baseline. Among both sexes, total costs were approximately $2,000 lower among consumers of >1-6 drinks per week than abstainers. The lower costs associated with moderate drinking were most apparent among participants with cardiovascular disease (CVD) and for hospitalization costs for CVD among healthy participants. Former drinkers had the highest costs. [ABSTRACT FROM AUTHOR]

Objectives: We developed a source documentation approach that identified fluoride content of drinking water at the state or local level to estimate fluoride concentrations from public water systems. We then compared estimates from this approach with estimates obtained from a single source, the 1992 Centers for Disease Control and Prevention (CDC) Fluoridation Census.Methods: We used residential histories from a case-control study. For each residence we attempted to determine fluoride concentrations using the 1992 CDC Fluoridation Census. For the source documentation method we utilized multiple sources from state and local contacts to verify and collect additional data. We compared the fluoride estimates obtained by the two methods.Results: When fluoride values were found using both methods, there was good correlation (Kendall's tau = 0.85; 95% confidence interval = 0.79, 0.90) and concordance was 96 percent. We obtained over 99 percent of the fluoride values needed using source documentation as compared to 49 percent of the values needed when we used a single publication. When fluoride values were missing using the 1992 CDC Fluoridation Census, 21 percent had source documentation estimates of at least 0.7 ppm.Conclusions: Researchers need to consider limitations of using a secondary data source to estimate fluoride in drinking water, particularly in studies where exposure to fluoride is the primary exposure of interest.

OBJECTIVE -- To study whether obese individuals, who are at higher risk for diabetes and disparities in care than nonobese individuals, are more likely to have undiagnosed diabetes. RESEARCH DESIGN AND METHODS -- We performed an analysis of 5,514 adult participants in the 1999-2004 National Health and Nutrition Examination Survey. Particpants were interviewed about sociodemographic and medical data, including whether they had been diagnosed with diabetes, and were examined for height, weight, and fasting plasma glucose level ≥126 mg/dl or by previous physician diagnosis. After categorizing participants into normal weight, overweight, and obese according to BMI, the prevalance and diagnosis of diabetes across BMI categories was compared using χsup2;. RESULTS-- Of the 9.8% (weighted sample) of participants who had diabetes, based on fasting glucose levels and self-reported diagnosis, 28.1% were undiagnosed, translating to an estimated 5.2 million people in the U.S. population. The proportion undiagnosed was not significantly different among normal-weight (22.2%), overweight (32.5%), or obese adults (27.4%). Nevertheless, obese adults comprise more than half of the undiagnosed diabetes cases (2.7 million). Relative to normal-weight adults, the adjusted odds ratio (OR) for having undiagnosed diabetes was 1.50 (0.73-3.08) in overweight and 1.37 (0.72-2.63) in obese adults. CONCLUSIONS-- Despite a higher underlying risk of diabetes and widespread clinical recognition of this higher risk, obesity does not increase the likelihood that an individual's diabetes will be diagnosed.

Affective polarization—the tendency for individuals to exhibit animosity toward those on the opposite side of the partisan divide—has increased in the United States in recent years. This article presents evidence that this trend may have consequences for Americans' health. Structural equation model analyses of nationally representative survey data from Pew Research Center's American Trends Panel (n = 4,685) showed heterogeneous relationships between affectively polarized attitudes and self-rated health. On one hand, such attitudes were directly negatively associated with health such that the polarized political environment was proposed to operate as a sociopolitical stressor. Simultaneously, affective polarization was positively associated with political participation, which in turn was positively associated with health, although the direct negative effect was substantially larger than the indirect positive one. These results suggest that today's increasingly hostile and pervasive form of partisanship may undermine Americans' health even as it induces greater political engagement. [ABSTRACT FROM AUTHOR]

BACKGROUND: There are limited data regarding the relationship between cannabinoids and metabolic processes. Epidemiologic studies have found lower prevalence rates of obesity and diabetes mellitus in marijuana users compared with people who have never used marijuana, suggesting a relationship between cannabinoids and peripheral metabolic processes. To date, no study has investigated the relationship between marijuana use and fasting insulin, glucose, and insulin resistance. METHODS: We included 4657 adult men and women from the National Health and Nutrition Examination Survey from 2005 to 2010. Marijuana use was assessed by self-report in a private room. Fasting insulin and glucose were measured via blood samples after a 9-hour fast, and homeostasis model assessment of insulin resistance (HOMA-IR) was calculated to evaluate insulin resistance. Associations were estimated using multiple linear regression, accounting for survey design and adjusting for potential confounders. RESULTS: Of the participants in our study sample, 579 were current marijuana users and 1975 were past users. In multivariable adjusted models, current marijuana use was associated with 16% lower fasting insulin levels (95% confidence interval [CI], -26, -6) and 17% lower HOMA-IR (95% CI, -27, -6). We found significant associations between marijuana use and smaller waist circumferences. Among current users, we found no significant dose-response. CONCLUSIONS: We found that marijuana use was associated with lower levels of fasting insulin and HOMA-IR, and smaller waist circumference. [ABSTRACT FROM AUTHOR]

Objective: This study examined the frequency and temporal trends of alcohol use among women with and without myocardial infarction (MI) in the United States. Method: We pooled yearly surveys from the nationally representative Behavioral Risk Factor Surveillance System between 1997 and 2008. Subjects for this study were 1,186,951 women, of whom 50,055 had a previous MI. Yearly weighted prevalence rates and frequencies of drinking behaviors were calculated for alcohol use in women with and without previous MI. Results: Fewer post-MI women consumed alcohol than other women (24% vs. 46%), but the prevalence of drinking increased over time in both groups. Nearly one third of post-MI women and half of all women consumed more than one drink per day. Heavy episodic drinking (four or more drinks per day) increased over time in both groups. After multivariable adjustment, post-MI women were less likely to report any drinking or consuming more than one drink per day, but the prevalence of heavy episodic drinking and the increasing trends over time were similar in both groups. Conclusions: Heavy alcohol use and heavy episodic drinking among women in the United States increased over the past decade, regardless of MI history. Although this may have reflected the influence of national guidelines on alcohol consumption, the increase in heavy episodic drinking suggests that better efforts to educate clinicians and women about the harms from excessive alcohol are required.

Objective To examine associations of proximity to major roadways, sustained exposure to fine particulate matter (PM 2.5 ), and acute exposure to ambient air pollutants with adipokines and measures of glucose homeostasis among participants living in the northeastern United States. Methods We included 5958 participants from the Framingham Offspring cohort examination cycle 7 (1998–2001) and 8 (2005–2008) and Third Generation cohort examination cycle 1 (2002–2005) and 2 (2008–2011), who did not have type 2 diabetes at the time of examination visit. We calculated 2003 annual average PM 2.5 at participants' home address, residential distance to the nearest major roadway, and daily PM 2.5 , black carbon (BC), sulfate, nitrogen oxides (NO x ), and ozone concentrations. We used linear mixed effects models for fasting glucose, insulin, and homeostasis model assessment of insulin resistance (HOMA-IR) which were measured up to twice, and used linear regression models for adiponectin, resistin, leptin, and hemoglobin A1c (HbA1c) which were measured only once, adjusting for demographics, socioeconomic position, lifestyle, time, and seasonality. Results The mean age was 51 years and 55% were women. Participants who lived 64 m (25th percentile) from a major roadway had 0.28% (95% CI: 0.05%, 0.51%) higher fasting plasma glucose than participants who lived 413 m (75th percentile) away, and the association appeared to be driven by participants who lived within 50 m from a major roadway. Higher exposures to 3- to 7-day moving averages of BC and NO x were associated with higher glucose whereas the associations for ozone were negative. The associations otherwise were generally null and did not differ by median age, sex, educational attainment, obesity status, or prediabetes status. Conclusions Living closer to a major roadway or acute exposure to traffic-related air pollutants were associated with dysregulated glucose homeostasis but not with adipokines among participants from the Framingham Offspring and Third Generation cohorts.

Background: Inequities in health care predispose Indigenous populations to poor health outcomes. The objective of this study was to examine patient survival and other post-transplant outcomes of kidney transplantation among Indigenous patients compared with non-Indigenous populations., Methods: A systematic review of MEDLINE, EMBASE, and Google Scholar was undertaken from inception to September 30, 2019, using a computerized search. Publication descriptors and methodological and statistical details were extracted. Articles were assessed using the methodological index for non-randomized studies (MINORS) scale., Results: Twelve studies were included. All studies were retrospective and published between 2004 and 2018. Mean Indigenous patient age was 40 (range: 8-76), while non-Indigenous was 41 (range: 6-74). Mean sample size for Indigenous populations was 398 (range: 24-1459), while for non-Indigenous patients was 1102 (range: 53-7555). Eight studies examined indigenous populations in Australia, two in Canada, one in the United States, and one in New Zealand. All studies were considered of high methodological quality and clinically homogenous. Results indicated that patient survival, graft survival, and delayed graft function were significantly reduced among Indigenous populations compared with non-Indigenous populations., Conclusions: Post-transplant outcomes among various Indigenous populations are significantly worse compared with non-Indigenous populations. The reasons for poor outcomes are likely multifactorial. Improved standardized reporting of transplant outcomes of Indigenous patients is necessary to better inform healthcare services and improve clinical outcomes., (© 2019 John Wiley & Sons A/S.

The study seeks to describe the use of dietary supplements promoted for cardiovascular health and the relation between supplement use and coronary artery disease (CAD) and the presence of major CAD risk factors. The aim is also to explore whether use of medications for the treatment of cardiovascular disease or diabetes mellitus (DM) is associated with supplement use. We performed a cross-sectional analysis of the 1999 to 2002 National Health and Nutrition Examination Survey (NHANES) of 6,671 adults (representing 119.3 million US adults) aged ≥40 years. We categorized adults into 4 nonoverlapping groups as (1) having reported CAD or stroke (CAD/stroke), (2) DM without CAD/stroke, (3) hypertension (HTN) or hypercholesterolemia (HC) without CAD/stroke or DM (HTN/HC), or (4) none of these conditions (no reported CAD/CAD risk) and performed weighted (NHANES) multiple logistic regression to determine the odds of using supplements (reference group, no reported CAD/CAD risk). After controlling for sociodemographics, health, and lifestyle factors, we found that persons with CAD/Stroke used more supplements (any), vitamin E, folic acid, and niacin, and less fish oil. Those with DM used less coenzyme Q10, and adults with HTN/HC used more supplements (any), herbs (any), and ginseng. Adults with CAD/stroke who used medications for the treatment of cardiovascular disease or DM were more likely to use folic acid compared with those who did not use medications for these conditions. In adults with CAD/stroke, DM, or HTN/HC, those who did not use medications for these conditions were more likely to use herbs and other select supplements. In conclusion, use of dietary supplements is common in those with CAD or CAD risks. [Copyright &y& Elsevier]
