BACKGROUND: Previous evidence showed a possible link of dyslipidemia with bone health. Nevertheless, the correlation of remnant cholesterol (RC) with bone mineral density (BMD) has yet to be well investigated. This study investigated the association of RC with total spine BMD in general Americans.
METHODS: This study explored the relationship of RC with total spine BMD in subjects aged ≥ 20 years from the National Health and Nutrition Examination Survey (NHANES) 2013-2018. After adjusting for covariates, multivariate linear regression and stratified analyses were conducted to determine the correlation of serum RC with total spine BMD in adult Americans. Restricted cubic spline (RCS) was applied to examine the nonlinear association of serum RC with total spine BMD.
RESULTS: This study included 3815 individuals ≥ 20 years old, 1905 (49.93%) of whom were men and 1910 (50.07%) of whom were women. After adjusting for all covariates, the results showed a negative relationship of serum RC with total spine BMD (β= -0.024, 95% CI: -0.039, -0.010). The interaction tests of age, sex, race, and BMI showed no statistically significant effects on the association. The RCS also indicated a negative linear correlation of serum RC with total spine BMD (nonlinear P = 0.068, overall P < 0.001). Moreover, RC had a stronger effect on total spine BMD than total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C).
CONCLUSIONS: This study found that serum RC was negatively related to total spine BMD in U.S. adults. These findings emphasized the important role of RC in bone health in American adults.

Cardiovascular disease (CVD) continues to pose a global health challenge, demonstrating significant disparities in occurrence among various populations. A wide number of research studies have indicated a higher prevalence of cardiovascular disease in South Asian immigrants compared to the local American population. The demand to improve the cardiovascular benefits of immigrants is increasing, which calls for further research with larger and more diverse population samples. This study will investigate the major causes of this variation, which include genetically diverse characteristics and changes in nutritional status among the study population groups. To assess the increase in the prevalence of cardiovascular disease among South Asian populations compared to the US population, a narrative review of accessible data is carried out. The data in support of the present document are from the Centre for Disease Prevention and Control, Statistics for Heart Diseases and Stroke 2023, a trend analysis about incidences of cardiac diseases and global burden in 2017, all dating back to the last two decades. Relevant articles from PubMed and Google Scholar have also been included, as appropriate, and their references are provided wherever necessary. Graphs for the geographical variations in disease incidence are produced using Microsoft Excel (Microsoft® Corp., Redmond, WA). The review shows that there is a significant decline in the prevalence of CVD among American citizens when compared to the steady increase in the number of cases among South Asians, which is attributed to the unique genetic predisposition of South Asians to be more prone to CVDs. The changing dietary habits also play an important role in the fall in HDL levels in South Asians when compared to Americans. This is driven by genetic disparities, including the APOA1 and APOA2 genes, and nutritional disparities, including variance in quality and quantity of dietary consumption. Addressing the escalating cases of CVD among South Asians necessitates additional research to enhance proactive preventive measures and implement screening programs specifically tailored to address prevalent risk factors within the population.

This study determined consumers\' attitudes towards physical and mental wellness related to red meat consumption and their willingness to pay (WTP) more for the meat. In 2019, two online surveys of red meat eaters were conducted in the USA (n = 1000) and Australia (n = 523) using commercial platforms. Results showed that over 90% of respondents indicated interest in purchasing red meat to improve their wellness status. Additionally, about 85% indicated their WTP more for red meat for its wellness benefits, with Americans indicating stronger willingness than Australian respondents. The potential of meat consumption to improve overall wellness among red meat eaters was a dominant factor influencing consumers\' WTP more. Other factors that increased WTP included frequency of meat consumption, physical exercise, sleep quality, number of children in a household, partnership status, and economic position. Outcomes from this study highlight a unique opportunity for the meat industry to position meat on its qualities that include wellness improvement if backed up with robust scientific evidence.

UNASSIGNED: Little is known about the measurement invariance (MI) of resilience instruments in cancer care. This study was designed to examine MI of 10-Item Resilience Scale (RS-SC-10) in Americans and Chinese with cancer using propensity score-based multidimensional item response theory (MIRT) analysis.
UNASSIGNED: A sample of 924 patients were enrolled in the Be Resilient to Cancer trial involving 1 hospital in America and 3 hospitals in China. Data were collected from the RS-SC-10 and Hospital Anxiety and Depression Scale. Propensity score matching and MIRT were performed to evaluate Differential Item Function. Integrated Discrimination Improvement and Net Reclassification Improvement were used to indirectly estimate the MI through incremental prediction ability of MIRT-based score over total score.
UNASSIGNED: RS-SC-10 retained 10 items with monotonous thresholds and its original two-factor structure. Nonuniform Differential Item Function was recognized in Item 4 (P ​= ​0.0011, Δ%β1 ​= ​4.15%) and Item 8 (P ​= ​0.0017, Δ%β1 ​= ​5.99%). Net Reclassification Improvement ranged from 9.04% to 35.01%, and Integrated Discrimination Improvement ranged from 8.82% to 20.60%.
UNASSIGNED: Although partial MI has been identified between Americans and Chinese, RS-SC-10 remains a critical indicator to emotional distress in cancer care.

There is paucity of data on Atrial Fibrillation (AF) management and associated clinical outcomes among Asian Americans. This study sought to investigate baseline risk factor profiles, racial disparities in clinical management and adverse clinical outcomes among White and Asian Americans.
We used National Cardiovascular Data Registry (NCDR®) Practice Innovation and Clinical Excellence (PINNACLE) registry and linked Centers of Medicare and Medicaid Services data to identify Asian and White patients with AF between January 1, 2013-June 30, 2018. We compared rates of baseline risk factors, management strategies (rate versus rhythm control), anticoagulation use and rates of adverse events between racial groups. The two race groups were compared using hierarchical multivariable adjusted regression models to account for site and confounders.
In total, 1,359,827 patients (18,793 Asians and 1,341,034 Whites) were included in our analysis. Compared to White Americans, Asian Americans were more likely to use a rate control strategy (Odds Ratio [OR]: 1.20, 95% Confidence Interval [CI]: 1.15-1.25) and lower odds of rhythm control strategy (atrial ablations, cardioversions, or use of antiarrhythmic drugs) (OR: 0.83, 95% CI: 0.80-0.87) in adjusted analysis. Use of oral anticoagulants and direct oral anticoagulants were similar. There were no significant race-based differences in likelihood of all-cause mortality, stroke, and bleeding requiring hospitalization. Analyses performed using propensity score matching were consistent with the main results.
Asian Americans with AF have a lower likelihood of being managed with rhythm control strategies. Overall use of OAC and AF related adverse events remain similar between the two racial groups.

The purpose of this study was to advance a theoretical understanding of the effects of impoverished neighborhoods on mental health and to inform policy measures encouraging residents to leave such neighborhoods. To do this, we investigated whether individuals\' perceived neighborhood disadvantage served as a risk factor for clinical depression in a nationally representative sample of African Americans and Caribbean Blacks. We performed logistic regression analysis on stratified socioeconomic status (SES) subsamples from the National Survey of American Life sample of 5,019 African Americans and Caribbean Blacks. The association between perceived neighborhood social disorder and past-year depression was statistically significant for low-SES individuals (at or below the federal poverty line; odds ratio [OR] = 1.73, 95% confidence interval [CI] [1.07, 2.81], p = 0.026) and at the boundary of significance for middle-SES individuals (between 100% and 300% of the poverty line; OR = 1.74, 95% CI [1.00, 3.02], p = 0.052), but not for high-SES individuals (at or above 300% of the poverty line). Results suggest, at least for low- and middle-income African Americans, perceived neighborhood social disorder is a risk factor for depression. U.S. housing policies aimed at neighborhood improvement and poverty de-concentration may benefit the mental health of low-income African Americans and Caribbean Blacks.

BACKGROUND: There is a widespread belief that Asians are more susceptible to hemorrhagic transformation (HT) after receiving recombinant tissue-type plasminogen activator (rt-PA) for acute ischemic stroke (AIS). However, this has not been examined in clinical practice. This study aims to compare the incidence of symptomatic hemorrhagic transformation (SHT) among thrombolysis-treated AIS patients in China and in the United States.
METHODS: We compared 212 consecutive patients receiving thrombolysis within 4.5 hours of onset ± endovascular therapy from an American (n = 86) and a Chinese Stroke Center (n = 126). SHT was defined using various definitions based on the National Institute for Neurological Disorders and Stroke Recombinant Tissue Plasminogen Activator (NINDS rt-PA) trials, European-Australian Cooperative Acute Stroke Study 2 (ECASS2), and a modified version of Safe Implementation of Thrombolysis in Stroke-Monitoring Study (mSITS-MOST) study criteria. We used Firth logistic regression to adjust for confounding variables and to identify potential predictors.
RESULTS: American patients were older, and had higher prevalence of diabetes, hypertension, cardiac disease, and prestroke use of antithrombotics. They also had higher baseline serum glucose, shorter onset-to-treatment time, and fewer endovascular treatments. The rates of SHT were higher in the American cohort compared to the Chinese cohort: 18.6% versus 14.3% based on NINDS definition of SHT; 15.1% versus 12.7% based on ECASS2; and 11.6% versus 7.2% based on mSITS-MOST. However, none of these differences were significant (unadjusted and adjusted P values > .05). Fatal HT was comparable in Americans versus Chinese (8.1% versus 8.7%). Serum glucose emerged as an independent predictor of SHT (P = .024).
CONCLUSIONS: In our cohorts, the rate of SHT after thrombolysis is equivalent between Chinese and North American stroke patients.

BACKGROUND: Social support has been associated with physical and mental health; however, the relationship between social support and diet quality is not well understood.
OBJECTIVE: The purpose of this research was to assess the relationship between social support and overall diet quality among US adults.
METHODS: This study was a secondary analysis of data from adults aged 40 years and older who participated in the cross-sectional 2007-2008 National Health and Nutrition Examination Survey (N=3,243).
METHODS: Social support was determined by a modification of the Rees Social Support Index (SSI), which is the sum of five dichotomized variables addressing emotional support, financial support, marital status, close friends, and religious service attendance. Overall diet quality was measured by the Healthy Eating Index-2010 (HEI-2010) and calculated from the mean of two 24-hour dietary recalls.
METHODS: SAS survey procedures were used to incorporate the appropriate sample design weights. Unweighted frequencies are reported along with weighted means and standard errors (SE). Multivariable linear regression was used to compare the total HEI-2010 scores among the six SSI groups with additional models controlling for sex, age, race/ethnicity, income level, and education level, and stratifying by sex.
RESULTS: In an unadjusted model, the mean total HEI-2010 score for those with an SSI score of 0 (n=37) was 50.0 (SE=2.83) compared to 57.1 (SE=0.89) for those with SSI score of 5 (n=676) (P<0.0001). The results were no longer statistically significant when adjusted for age, sex, race/ethnicity, income, and education level (P=0.14). However, when stratified by sex and adjusted for other demographics, higher SSI scores were associated with higher HEI-2010 scores compared to lower SSI scores in men (P=0.02), but there was no significant difference among SSI scores and HEI-2010 scores in women (P=0.43).
CONCLUSIONS: This study suggests a positive relationship between social support and overall diet quality among middle-aged and older men, but not women, in the United States.

BACKGROUND: Dynamic diurnal changes in 24-h ambulatory systolic blood pressure (SBP) are associated with increased cardiovascular risk. We compared ambulatory BP dynamics in Japanese and American black and white populations with treatment-resistant hypertension.Methods and Results:Both HTN-Japan (n=41) and SYMPLICITY HTN-3 (n=384 white and n=140 black patients) enrolled patients with office SBP ≥160 mmHg and 24-h ambulatory SBP ≥135 mmHg while on ≥3 antihypertensive medications. Indices of circadian variation in ambulatory BP, including morning and nighttime dynamic surges, were retrospectively compared. All 3 cohorts had similar baseline office SBP. The Japanese cohort had significantly lower body mass index, less obstructive sleep apnea, and less hypercholesterolemia than the black and white cohorts, but significantly greater morning SBP levels, including moving peak morning SBP (183 vs. 169 vs. 169 mmHg, P<0.001), morning dynamic surge (37.9 vs. 28.6 vs. 24.2 mmHg, P<0.001) and nighttime dynamic surge (24.9 vs. 8.3 vs. 7.7 mmHg, P<0.001). These racial differences in SBP surge parameters persisted despite adjustment for baseline demographic population differences through multivariate regression.
CONCLUSIONS: Greater diurnal BP variability, including dynamic surges, in Japanese compared with black and white patients may indicate ethnic differences in the underlying BP regulatory mechanism of resistant hypertension. These differences may be important to take into consideration for more specific drug and device-based therapy strategies based on ethnicity.

Arterial hypertension is prevalent in the black population in the United States. It is directly related to cardiovascular and kidney damage. Its pathogenesis is complex and includes the high incidence of obesity, salt sensitivity and the activation of the renin-angiotensin-aldosterone system. This complexity requires a therapeutic combination that includes changes in dietary habits and appropriate antihypertensive regimes. The International Society of Hypertension in Blacks recommends initiating dietary intervention for values of systolic/diastolic arterial blood pressure above 115/75 mmHg and maintaining arterial blood pressure below 135/85 mmHg using appropiate antihypertensive medication. The most adequate antihypertensive drug for this population has yet to be determined.
