ObjectiveThe objective of this study is to determine associations between anthropometry and echocardiographic measures of cardiac structure and function in Hispanic/Latinos.MethodsA total of 1,824 participants from ECHO-SOL were included. We evaluated associations between echocardiographic measures of left ventricular structure and function and anthropometric measures using multivariable-adjusted linear and logistic regression models adjusting for traditional cardiovascular risk factors.ResultsThe mean age was 56 ± 0.17 years, 57% were women. The mean body mass index (BMI) was 30 ± 9.4 kg m-2, waist circumference (WC) was 100 ± 18 cm, and waist-to-hip ratio (WHR) was 0.93 ± 0.15. Adjusted analysis showed that 5-unit increment in BMI and 5-cm increase in WC was associated with 3.4 ± 0.6 and 1.05 ± 0.05 g m-2.7 (p

Importance: Apolipoprotein B (apoB) distribution and its implications as an atherosclerotic cardiovascular disease (ASCVD) risk-enhancing factor among individuals of diverse Hispanic or Latino backgrounds have not been described., Objective: To describe the distribution of apoB in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) cohort and to characterize associations of baseline sociodemographic and clinical variables with apoB and self-identified Hispanic or Latino background., Design, Setting, and Participants: The HCHS/SOL was a prospective, population-based cohort study of diverse Hispanic or Latino adults living in the US who were recruited and screened between March 2008 and June 2011. Sampling weights were used to generate a population-based sample of Hispanic or Latino participants aged 18 to 74 years who resided in 4 US metropolitan areas (Bronx, New York; Chicago, Illinois; Miami, Florida; and San Diego, California). ApoB concentration was measured in participants from the HCHS/SOL, and apoB tertiles were compared across demographic groups, including self-identified Hispanic or Latino background. Median percentage continental genetic ancestry (West African, Amerindian, and European) was compared across apoB tertiles., Exposure: ApoB measured in mg/dL from serum or plasma using an immunoturbidimetric assay., Main Outcomes and Measures: ApoB tertiles were determined, and traditional lipids were evaluated across apoB tertiles. ApoB and traditional lipid measurements were assessed across ASCVD risk categories. Additionally, scatterplots were created to observe correlations between apoB and low-density lipoprotein cholesterol or non-high-density lipoprotein cholesterol., Results: Overall mean (SD) apoB concentration was 99.8 (0.4) mg/dL, with male participants displaying significantly higher mean levels than female participants (102.4 vs 97.4 mg/dL, respectively). Mean (SD) participant age was 41.1 (0.8) years, and 8376 participants (51.9%) were female. ApoB levels were higher among older age groups. There was significant heterogeneity in mean apoB concentrations across self-identified Hispanic or Latino background groups, ranging from 95.1 mg/dL in Dominican individuals to 104.8 mg/dL in Cuban individuals. The prevalence of elevated apoB (≥130 mg/dL) was greater across higher predicted ASCVD risk categories. Among participants with a 10-year predicted ASCVD risk of 7.5% or higher, 26.5% had an elevated apoB. Median West African ancestry was lower across higher tertiles of apoB., Conclusions and Relevance: In this cohort study among participants from the HCHS/SOL, elevated apoB was present in one-quarter of a diverse cohort study of Hispanic or Latino individuals who were at intermediate or high predicted ASCVD risk. Differences in apoB distribution among Hispanic or Latino individuals may have important implications for apoB's use in ASCVD risk assessment.

Background: Hispanics/Latinos of Dominican background living in United States (US) have the highest hypertension prevalence compared with other Hispanic/Latino persons., Objective: To understand cardiovascular health among Dominicans, we evaluated hypertension prevalence and risk factors among Dominicans from the US and Dominican Republic (DR) using data from Hispanic Community Health Study/ Study of Latinos [HCHS/SOL] and the Prevalencia de Hipertension Arterial y Factores de Riesgo Cardiovasculares en la República Dominicana al 2017 (ENPREFAR-HAS 17) study., Methods: Hypertension was defined as blood pressure ≥140/90 mmHg, self-reported hypertension, or antihypertensive use. Exposures included sociodemographic/socioeconomic, clinical, and lifestyle/behavioral characteristics. Weighted generalized linear models were used to estimate associations between study characteristics and hypertension prevalence (PR = prevalence ratio), age-and-sex adjusted. HCHS/SOL (n = 1,473, US Dominicans; mean age 41 years, 60.4% female) was analyzed with survey procedures, while ENPREFAR-HAS 17 (n = 2,015 DR Dominicans; mean age 40 years, 50.3% female) was analyzed with statistical analyses for simple random sampling., Results: Hypertension prevalence was 30.5% and 26.9% for DR and US Dominicans, respectively. Hypertension control was low in both cohorts (36.0% DR, 35.0% US). Alcohol use among DR Dominicans was inversely associated with hypertension prevalence (PR DR = 0.8) with no association among US Dominicans. In both settings, diabetes (PR DR = 1.4; PR US = 1.4) and obesity (PR DR = 1.8; PR US = 2.0) were associated with greater hypertension prevalence in Hispanics/Latinos of Dominican background. Physical activity was lower among US Dominicans (PR = 0.80) but higher among DR Dominicans (PR = 1.16); all p < 0.05., Conclusions: Variations in social, lifestyle/behavioral, and clinical characteristics associated with hypertension among Dominicans in the US and DR were identified, suggesting that social context and cultural factors matter among immigrant populations., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2024 The Author(s).)

Background: Pre-heart failure (pre-HF) is an entity known to progress to symptomatic heart failure (HF)., Objectives: This study aimed to characterize pre-HF prevalence and incidence among Hispanics/Latinos., Methods: The Echo-SOL (Echocardiographic Study of Latinos) assessed cardiac parameters on 1,643 Hispanics/Latinos at baseline and 4.3 years later. Prevalent pre-HF was defined as the presence of any abnormal cardiac parameter (left ventricular [LV] ejection fraction <50%; absolute global longitudinal strain <15%; grade 1 or more diastolic dysfunction; LV mass index >115 g/m 2 for men, >95 g/m 2 for women; or relative wall thickness >0.42). Incident pre-HF was defined among those without pre-HF at baseline. Sampling weights and survey statistics were used., Results: Among this study population (mean age: 56.4 years; 56% female), HF risk factors, including prevalence of hypertension and diabetes, worsened during follow-up. Significant worsening of all cardiac parameters (except LV ejection fraction) was evidenced from baseline to follow-up (all P < 0.01). Overall, the prevalence of pre-HF was 66.7% at baseline and the incidence of pre-HF during follow-up was 66.3%. Prevalent and incident pre-HF were seen more with increasing baseline HF risk factor burden as well as with older age. In addition, increasing the number of HF risk factors increased the risk of prevalence of pre-HF and incidence of pre-HF (adjusted OR: 1.36 [95% CI: 1.16-1.58], and adjusted OR: 1.29 [95% CI: 1.00-1.68], respectively). Prevalent pre-HF was associated with incident clinical HF (HR: 10.9 [95% CI: 2.1-56.3])., Conclusions: Hispanics/Latinos exhibited significant worsening of pre-HF characteristics over time. Prevalence and incidence of pre-HF are high and are associated with increasing HF risk factor burden and with incidence of cardiac events., Competing Interests: Funding Support and Author Disclosures The baseline examination of HCHS/SOL was conducted as a collaborative study supported by contracts from the National Heart, Lung, and Blood Institute to the University of North Carolina (N01-HC65233), University of Miami (N01-HC65234), Albert Einstein College of Medicine (N01-HC65235), Northwestern University (N01-HC65236), and San Diego State University (N01-HC652237).

Importance: Lipoprotein(a) (Lp[a]) is a genetically determined risk-enhancing factor for atherosclerotic cardiovascular disease (ASCVD). The Lp(a) distribution among the diverse Hispanic or Latino community residing in the US has not been previously described, to the authors' knowledge., Objective: To determine the distribution of Lp(a) levels across a large cohort of diverse Hispanic or Latino adults living in the US and by key demographic groups., Design, Setting, and Participants: The Hispanic Community Health Study/Study of Latinos (HCHS/SOL) is a prospective, population-based, cohort study of diverse Hispanic or Latino adults living in the US. At screening, participants aged 18 to 74 years were recruited between 2008 and 2011 from 4 US metropolitan areas (Bronx, New York; Chicago, Illinois; Miami, Florida; San Diego, California). HCHS/SOL included 16 415 noninstitutionalized adults recruited through probability sampling of randomly selected households. The study population represents Hispanic or Latino participants from diverse self-identified geographic and cultural backgrounds: Central American, Cuban, Dominican, Mexican, Puerto Rican, and South American. This study evaluated a subset of HCHS/SOL participants who underwent Lp(a) measurement. Sampling weights and surveys methods were used to account for HCHS/SOL sampling design. Data for this study were analyzed from April 2021 to April 2023., Exposure: Lp(a) molar concentration was measured by a particle-enhanced turbidimetric assay with minimized sensitivity to apolipoprotein(a) size variation., Main Outcome and Measure: Lp(a) quintiles were compared using analysis of variance among key demographic groups, including self-identified Hispanic or Latino background. Median percentage genetic ancestry (Amerindian, European, West African) were compared across Lp(a) quintiles., Results: Lp(a) molar concentration was measured in 16 117 participants (mean [SD] age, 41 [14.8] years; 9680 female [52%]; 1704 Central American [7.7%], 2313 Cuban [21.1%], 1436 Dominican [10.3%], 6395 Mexican [39.1%], 2652 Puerto Rican [16.6%], 1051 South American [5.1%]). Median (IQR) Lp(a) level was 19.7 (7.4-59.7) nmol/L. Across Hispanic or Latino background groups, there was significant heterogeneity in median Lp(a) levels ranging from 12 to 41 nmol/L in those reporting a Mexican vs Dominican background. Median (IQR) West African genetic ancestry was lowest in the first quintile of Lp(a) level and highest in the fifth quintile (5.5% [3.4%-12.9%] and 12.1% [5.0%-32.5%]; respectively; P < .001), whereas the converse was seen for Amerindian ancestry (32.8% [9.9%-53.2%] and 10.7% [4.9%-30.7%], respectively; P < .001)., Conclusions and Relevance: Results of this cohort study suggest that differences in Lp(a) level distribution across the diverse US Hispanic or Latino population may carry important implications for the use of Lp(a) level in ASCVD risk assessment for this group. Cardiovascular outcomes data are needed to better understand the clinical impact of differences in Lp(a) levels by Hispanic or Latino background.

Objective: To assess the prevalence of low-flow state (LFS) with left ventricular (LV) stroke volume index of less than 35 mL/m 2 and the demographics, clinical and echocardiographic characteristics associated with LV remodeling and function in a Hispanic/Latino population., Participants and Methods: The study included 1346 asymptomatic participants from the Hispanic Community Health Study/Study of Latinos with normal LV ejection fraction (≥55%) and no valvular heart disease. LV volume, mass and left atrial volume, LV ejection fraction, global longitudinal strain, and myocardial contraction fraction were measured by echocardiography. The participants were divided into LFS or normal flow state (NFS: stroke volume index ≥35 mL/m 2 ). Demographics, clinical and echocardiographic characteristics, and measures of LV remodeling and function were compared between the LFS and NFS groups., Results: The prevalence of LFS was 41%. In comparison with NFS, the LFS had lower LV mass index (77.2±0.96 g/m 2 vs 84.6±0.86 g/m 2 ; P <.001), left atrial volume index (20.6±0.35 mL/m 2 vs 23.5±0.37 mL/m 2 ; P <.001), global longitudinal strain (-16.8±0.16% vs -17.7±0.17%; P <.001), and myocardial contraction fraction (43.3±0.63% vs 55.7±0.64%; P <.001). There was no significant difference in the relative wall thickness (LFS: 0.40±0.004 vs NFS: 0.40±0.005; P =.57). The LFS group had significantly higher hemoglobin A1c (6.18±0.07% vs 5.97±0.04%; P =.01) than the NFS group., Conclusion: A high prevalence of LFS associated with echocardiographic characteristics reflecting unfavorable LV remodeling and function was observed in a Hispanic/Latino population. Further studies of the prognostic significance of LFS in a large multiethnic population are warranted., (© 2022 The Authors.)

Objective: The cross-sectional association between accelerometer-measured physical activity (PA), sedentary behaviour (SB) and cardiac structure and function is less well described. This study's primary aim was to compare echocardiographic measures of cardiac structure and function with accelerometer measured PA and SB., Methods: Participants included 1206 self-identified Hispanic/Latino men and women, age 45-74 years, from the Echocardiographic Study of Latinos. Standard echocardiographic measures included M-mode, two-dimensional, spectral, tissue Doppler and myocardial strain. Participants wore an Actical accelerometer at the hip for 1 week., Results: The mean±SE age for the cohort was 56±0.4 years, 57% were women. Average moderate to vigorous PA (MVPA) was 21±1.1 min/day, light PA was 217±4.2 min/day and SB was 737±8.1 min/day. Both higher levels of light PA and MVPA (min/day) were associated with lower left ventricular (LV) mass index (LVMI)/end-diastolic volume and a lower E/e' ratio. Higher levels of MVPA (min/day) were associated with better right ventricular systolic function. Higher levels of SB were associated with increased LVMI. In a multivariable linear regression model adjusted for demographics and cardiovascular disease modifiable factors, every 10 additional min/day of light PA was associated with a 0.03 mL/m 2 increase in left atrial volume index (LAVI) (p<0.01) and a 0.004 cm increase in tricuspid annular plane systolic excursion (p<0.01); every 10 additional min/day of MVPA was associated with a 0.18 mL/m 2 increase in LAVI (p<0.01) and a 0.24% improvement in global circumferential strain (p<0.01)., Conclusions: Our findings highlight the potential positive association between the MVPA and light PA on cardiac structure and function., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background: Nearly half of operative mortalities occur outside the traditionally studied 30-day period after surgery. To identify additional opportunities to improve surgical safety, the circumstances of deaths occurring 31-90 days after complex cancer surgery are analyzed., Patients and Methods: Patients aged ≥ 65 years who died within 90 days of complex cancer surgery for nonmetastatic cancer were analyzed in the Surveillance, Epidemiology, and End Results (SEER)-Medicare and the Connecticut Tumor Registry (CTR) databases., Results: Of the 36,114 patients undergoing complex cancer surgery from 2004 to 2013 in SEER-Medicare, 1367 (3.8%) died within 31-90 days ("late mortalities"). Seventy-eight percent of late mortalities were readmitted prior to death. The highest proportion of late mortalities occurred during a readmission (49%), and 11% were never discharged from their index admission. Cause of death (COD) was largely attributed to the malignancy itself (56%), which is unlikely to be the underlying cause. Of the noncancer COD, cardiac causes were most frequent (34%), followed by pulmonary causes (18%). Death was rarely attributed to thromboembolic disease (< 1%). The CTR provided location of death, which was most commonly in a hospital (65%) or nursing facility (20%); death at home was rare (6%)., Conclusions: The vast majority of patients dying between 31 and 90 days of surgery were admitted to a hospital or nursing facility at the time of their death after initially being discharged, and few patients died at home. Greater clarity in death documentation is needed to identify specific opportunities to rescue patients from fatal complications arising in the later postoperative period.

Background: Presence of cardiovascular disease (CVD) risk factors (RFs) should prompt patients and their providers to work aggressively towards controlling those that are modifiable. The extent to which a greater CVD RF burden is related to CVD RF control in a contemporary and diverse Hispanic/Latino population is not well-understood., Methods: Using multicenter community-based data from the Hispanic Community Health Study/Study of Latinos, we assessed the self-reported prevalence of hypertension, hypercholesterolemia, diabetes, and prevalent CVD (ischemic heart disease or stroke). We used contemporaneous guidelines to define RF control. Multivariable logistic regression for complex survey sampling was used to examine whether having more CVD RFs was associated with CVD RF control (adjusting for age, sex, Hispanic background group, education, and health insurance)., Results: Our sample included 8521 participants with at least one CVD RF or prevalent CVD. The mean age in HCHS/SOL target population was 49 (SE 0.3) years and 56% were women. Frequency of one, two, or three self-reported CVD RFs was 57%, 26%, 8%, respectively, and overall 9% of participants had prevalent CVD. After adjusting for sociodemographic factors, compared to those reporting one CVD RF, individuals with three CVD RFs were the least likely to have blood pressure, cholesterol, and glucose optimally controlled (odds ratio [OR]: 0.56; 95% confidence interval [CI]: 0.40-0.80). However, those with prevalent CVD were more likely to have all three risk factors controlled, (OR: 1.43; 95% CI: 1.01-2.01)., Conclusion: Hispanic/Latino adults with three major CVD RFs represent a group with poor overall CVD RF control. Secondary CVD prevention fares better. The potential contributors to inadequate CVD RF control in this highly vulnerable group warrants further investigation., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2021 The Authors.)

Background Our objective was to determine associations of occupational exposures with cardiac structure and function in Hispanic/Latino adults. Methods and Results Employed participants were included (n=782; 52% women, mean age 52.9 years). Occupational exposures to burning wood, vehicle exhaust, solvents, pesticides, and metals at the current and longest-held job were assessed by questionnaire. Survey multivariable linear regression analyses were used to model the relationship of each self-reported exposure with echocardiographic measures of cardiac structure and function. Exposure to burning wood at the current job was associated with decreased left ventricular (LV) ejection fraction (-3.1%; standard error [SE], 1.0 [ P =0.002]). When the analysis was restricted to exposure at the longest-held job, occupational exposure to burning wood was associated with increased LV diastolic volume (6.7 mL; SE, 1.6 [ P <0.0001]), decreased LV ejection fraction (-2.7%; SE, 0.6 [ P <0.0001]), worse LV global longitudinal strain (1.0%; SE, 0.3 [ P =0.0009]), and decreased right ventricular fractional area change (-0.02; SE, 0.004 [ P <0.001]). Exposure to pesticides was associated with worse average global longitudinal strain (0.8%; SE, 0.2 [ P <0.0001]). Exposure to metals was associated with worse global longitudinal strain in the 2-chamber view (1.0%; SE, 0.5 [ P =0.04]), increased stroke volume (3.6 mL; SE, 1.6 [ P =0.03]), and increased LV mass indexed to BSA (9.2 g/m 2 ; SE, 3.8 [ P =0.01]) or height (4.4 g/m 2.7 ; SE, 1.9 [ P =0.02]). Conclusions Occupational exposures to burning wood, vehicle exhaust, pesticides, and metals were associated with abnormal parameters of LV and right ventricular systolic function. Reducing exposures to toxic chemicals and particulates in the workplace is a potential opportunity to prevent cardiovascular disease in populations at risk.

Importance: During the past several decades, breast cancer incidence has been increasing for women younger than 40 years. The increase matches the decrease in parity, an established breast cancer risk factor, but secular trends in incidence have not been examined prior to the 1970s., Objective: To examine whether secular trends in parity explain the increase in breast cancer incidence among US women aged 25 to 39 years from 1935 to 2015., Design, Setting, and Participants: This population-based cohort study used population-based aggregate-level data from the Connecticut Tumor Registry (CTR) to examine breast cancer incidence and age-standardized rates among women aged 25 to 39 years from 1935 to 2015. National mean live births were calculated using birth data from the National Vital Statistics System (NVSS) from 1930 to 2015 (allowing for 5-year lag). Linear regression was used to compare a baseline model of year estimating age-adjusted breast cancer incidence rate with a model that adjusted for parity constructs., Main Outcomes and Measures: Breast cancer incidence rates among women aged 25 to 39 years from 1935 to 2015., Results: Among women in Connecticut aged 25 to 39 years from 1935 to 2015, incidence of breast cancer for women aged 25 to 39 years increased 0.65% (95% CI, 0.53%-0.77%) per year, from 16.3 breast cancer diagnoses per 100 000 women in 1935 to 38.5 breast cancer diagnoses per 100 000 women in 2015. This increase began nearly 4 decades before the secular decrease in parity (mean [SD] parity peaked at 2.26 [0.87] live births per woman in 1966 and in 2010 had decreased to 1.41 [0.71] live births per woman). Age-specific parity trends explained only 0% to 4% of the variability in incidence over time., Conclusion and Relevance: These findings suggest that breast cancer incidence for women aged 25 to 39 years has been significantly increasing since the 1930s and cannot be attributed to changes in parity over time.

Objective: Hispanics/Latinos, the largest immigrant population in the USA, undergo the process of acculturation and have a large burden of heart failure risk. Few studies have examined the association of acculturation on cardiac structure and function., Design: Cross-sectional., Setting: The Echocardiographic Study of Latinos., Participants: 1818 Hispanic adult participants with baseline echocardiographic assessment and acculturation measured by the Short Acculturation Scale, nativity, age at immigration, length of US residence, generational status and language., Primary and Secondary Outcome Measures: Echocardiographic assessment of left atrial volume index (LAVI), left ventricular mass index (LVMI), early diastolic transmitral inflow and mitral annular velocities., Results: The study population was predominantly Spanish-speaking and foreign-born with mean residence in the US of 22.7 years, mean age of 56.4 years; 50% had hypertension, 28% had diabetes and 44% had a body mass index >30 kg/m 2 . Multivariable analyses demonstrated higher LAVI with increasing years of US residence. Foreign-born and first-generation participants had higher E/e' but lower LAVI and e' velocities compared with the second generation. Higher acculturation and income >$20K were associated with higher LVMI, LAVI and E/e' but lower e' velocities. Preferential Spanish-speakers with an income <$20K had a higher E/e'., Conclusions: Acculturation was associated with abnormal cardiac structure and function, with some effect modification by socioeconomic status., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Background: Hispanics/Latinos represent the largest ethnic minority group in the United States. Atrial fibrillation (AF) is the most common cardiac arrhythmia in the United States., Objective: The purpose of this study was to provide data on the prevalence of AF and its correlates in a representative Hispanic/Latino population-based sample inclusive of all background groups., Methods: Hispanic Community Health Study/Study of Latinos participants (n=16,415; 60% women; 59% age >45 years) were enrolled between March 2008 and June 2011, representing individuals of Cuban, Dominican, Mexican, Puerto Rican, Central American, and South American heritage. AF was defined by the 12-lead electrocardiogram and/or participant self-report of a physician diagnosis. Hispanic background-specific AF prevalence rates were determined. Weighted sequential logistic regression models were adjusted for demographic factors (age and sex) and clinical variables (diabetes, hypertension, body mass index, tobacco use, and estimated glomerular filtration rate)., Results: The overall weighted prevalence of AF was 1.0% (n=162), with the highest prevalence in Hispanics of Dominican and Puerto Rican backgrounds (1.9% and 2.5% respectively) and the lowest in those of Mexican background (0.3%). Diabetes, hypertension, renal disease, left ventricular hypertrophy determined by the electrocardiogram, alcohol use, and English language preference (greater acculturation) (P < .01 for all) were significantly associated with higher AF prevalence. Multivariate analysis by Hispanic/Latino background group showed that Hispanics of Dominican and Puerto Rican backgrounds were at a 3- to 6-fold higher risk of AF than their Mexican counterparts., Conclusion: In a diverse representative population of Hispanics/Latinos, overall AF prevalence was low and varied significantly across Hispanic/Latino background groups independent of clinical or demographic factors., (Copyright © 2018 Heart Rhythm Society.

Objective: To describe the relationship of household secondhand smoke (SHS) exposure and cardiac structure and function., Methods: Participants (n=1069; 68 % female; age 45-74 years) without history of tobacco use, coronary artery disease or severe valvular disease were included. Past childhood (starting at age <13 years), adolescent/adult and current exposure to household SHS was assessed. Survey linear regression analyses were used to model the relationship of SHS exposure and echocardiographic measures of cardiac structure and function, adjusting for covariates (age, sex, study site, alcohol use, physical activity and education)., Results: SHS exposure in childhood only was associated with reduced E/A velocity ratio (β=-0.06 (SE 0.02), p=0.008). SHS exposure in adolescence/adult only was associated with increased left ventricular ejection fraction (LVEF) (1.2 (0.6), p=0.04), left atrial volume index (1.7 (0.8), p=0.04) and decreased isovolumic relaxation time (-0.003 (0.002), p=0.03). SHS exposure in childhood and adolescence/adult was associated with worse left ventricular global longitudinal strain (LVGLS) (two-chamber) (0.8 (0.4), p= 0.049). Compared with individuals who do not live with a tobacco smoker, individuals who currently live with at least one tobacco smoker had reduced LVEF (-1.4 (0.6), p=0.02), LVGLS (average) (0.9 (0.40), p=0.03), medial E' velocity (-0.5 (0.2), p=0.01), E/A ratio (-0.09 (0.03), p=0.003) and right ventricular fractional area change (-0.02 (0.01), p=0.01) with increased isovolumic relaxation time (0.006 (0.003), p=0.04)., Conclusions: Past and current household exposure to SHS was associated with abnormalities in cardiac systolic and diastolic function. Reducing household SHS exposure may be an opportunity for cardiac dysfunction prevention to reduce the risk of future clinical heart failure., Competing Interests: Competing interests: None declared.

Objective: We assessed the hypothesis that metabolic syndrome is associated with adverse changes in cardiac structure and function in participants of the Echocardiographic Study of Latinos (Echo-SOL)., Methods: Non-diabetic Echo-SOL participants were included in this cross-sectional analysis. Metabolic syndrome was defined according to the American Heart Association/National Heart, Lung, and Blood Institute 2009 Joint Scientific Statement. Survey multivariable linear regression analyses using sampling weights were used adjusting for multiple potential confounding variables. Additional analysis was stratified according to the presence/absence of obesity (body mass index (BMI) ≥25 kg/m 2 ) and the presence/absence of metabolic syndrome., Results: Within Echo-SOL, 1260 individuals met inclusion criteria (59% female; mean age 55.2 years). Compared with individuals without metabolic syndrome, those with metabolic syndrome had lower medial and lateral E' velocities (-0.4 cm/s, (SE 0.1), p=0.0002; -0.5 cm/s (0.2), p=0.02, respectively), greater E/E' (0.5(0.2), p=0.01) and worse two-chamber left ventricular longitudinal strain (0.9%(0.3), p=0.009), after adjusting for potential confounding variables. Increased left ventricular mass index (9.8 g/m 2 (1.9), p<0.0001 and 7.5 g/m 2 (1.7), p<0.0001), left ventricular end-diastolic volume (11.1 mL (3.0), p=0.0003 and 13.3 mL (2.7), p<0.0001), left ventricular end-systolic volume (5.0 mL (1.4), p=0.0004 and 5.7 mL (1.3) p<0.0001) and left ventricular stroke volume (10.2 mL (1.8), p<0.0001 and 13.0 mL (2.0), p<0.0001) were observed in obese individuals with and without metabolic syndrome compared with individuals with normal weight without metabolic syndrome. In sensitivity analyses, individuals with normal weight (BMI <25 kg/m 2 ) and metabolic syndrome had worse left ventricular global longitudinal strain (2.1%(0.7), p=0.002) and reduced left ventricular ejection fraction (-3.5%(1.4), p=0.007) compared with normal-weight individuals without metabolic syndrome., Conclusions: In a sample of US Hispanics/Latinos metabolic syndrome was associated with worse left ventricular systolic and diastolic function. Adverse changes in left ventricular size and function were observed in obese individuals with and without metabolic syndrome but decreased left ventricular function was also present in normal-weight individuals with metabolic syndrome., Competing Interests: Competing interests: None declared.

Objective: To study the associations of comprehensive measures of cardiac structure and function with multidimensional neurocognitive measures., Patients and Methods: The Echocardiographic Study of Latinos is a population-based cohort of Hispanic/Latino adults older than 45 years enrolled from October 1, 2011, through June 30, 2014. Neurocognitive measures included Word Fluency (WF), Brief-Spanish English Verbal Learning Test (B-SEVLT), and Digit Symbol Substitution Test. The B-SEVLT included B-SEVLT-recall and B-SEVLT-sum. Echocardiographic measures included cardiac structure, systolic and diastolic function, and myocardial strain. Multivariable regression models were fit using survey statistics and sampling probabilities., Results: A total of 1794 participants (mean age, 56±0.5 years; 56% women) were included in the analysis. In the adjusted model, higher left ventricular mass index was associated with lower B-SEVLT-sum and Digit Symbol Substitution Test scores. Left ventricular systolic dysfunction was associated with lower WF scores. Abnormal left ventricular geometry was associated with lower B-SEVLT-sum scores. Higher relative wall thickness was associated with B-SEVLT-recall and B-SEVLT-sum scores. Mitral annular relaxation velocities were associated with lower B-SEVLT-recall, B-SEVLT-sum, and WF scores. Higher mitral inflow to annular early diastolic velocity ratio was associated with lower B-SEVLT-recall and B-SEVLT-sum scores. Diastolic dysfunction was associated with lower B-SEVLT-sum scores. Finally, lower global longitudinal strain was associated with lower WF scores., Conclusion: Alterations in cardiac structure, systolic and diastolic function, and myocardial strain were associated with worse neurocognitive function. Further study is needed to determine the mechanisms (ie, impairment of cerebral flow and silent brain infarctions) mediating these heart-brain associations.

Objective: Cardiovascular disease is the leading cause of death in smokers and this relationship is complicated by the multiplicity of cardiovascular effects of smoking. However, the relationship between intensity and duration of cigarette smoking and echocardiographic measures of right and left ventricular structure and function has been poorly studied., Methods: We examined ECHO-SOL (Echocardiographic Study of Hispanics/Latinos) participants, a subset of the Hispanic Community Health Study/Study of Latinos. Participants were administered a detailed tobacco exposure questionnaire and a comprehensive echocardiography exam. Multivariable linear regression models (adjusted for age, sex, obesity, hypertension and diabetes statuses) were performed using sampling weights. Statistical significance was defined at p<0.01., Results: There were 1818 ECHO-SOL participants (57.4% women, mean age 56.4 years). Among current smokers (n=304), increased duration of smoking, as measured by a younger age of smoking initiation, was significantly associated with higher mean left ventricular mass (LVM) and lower right ventricular (RV) function (lower right ventricular stroke volumes). More cigarettes smoked per day was significantly associated with higher mean LVM, worse diastolic function (higher E/e' ratio), worse LV geometry (increased relative wall thickness) and worse RV function (decreasing right ventricular stroke volume). Among current smokers, higher mean lifetime pack-years (a combined measure of smoking intensity and duration) was associated with higher LVM, worse LV geometry, worse diastolic function, greater RV dilatation and worse RV function., Conclusions: There is a dose-response relationship between intensity and duration of cigarette tobacco smoking with unfavourable changes of multiple measures of right-sided and left-sided cardiac structure and function., Competing Interests: Competing interests: None declared.

Background: The prevalence estimates of statin eligibility among Hispanic/Latinos living in the United States under the new 2013 American College of Cardiology/American Heart Association (ACC/AHA) cholesterol treatment guidelines are not known., Methods and Results: We estimated prevalence of statin eligibility under 2013 ACC/AHA and 3rd National Cholesterol Education Program Adult Treatment Panel (NCEP/ATP III) guidelines among Hispanic Community Health Study/Study of Latinos (n=16 415; mean age 41 years, 40% males) by using sampling weights calibrated to the 2010 US census. We examined the characteristics of Hispanic/Latinos treated and not treated with statins under both guidelines. We also redetermined the statin-therapy eligibility by using black risk estimates for Dominicans, Cubans, Puerto Ricans, and Central Americans. Compared with NCEP/ATP III guidelines, statin eligibility increased from 15.9% (95% CI 15.0-16.7%) to 26.9% (95% CI 25.7-28.0%) under the 2013 ACC/AHA guidelines. This was mainly driven by the ≥7.5% atherosclerotic cardiovascular disease risk criteria (prevalence 13.9% [95% CI 13.0-14.7%]). Of the participants eligible for statin eligibility under NCEP/ATP III and ACC/AHA guidelines, only 28.2% (95% CI 26.3-30.0%) and 20.6% (95% CI 19.4-21.9%) were taking statins, respectively. Statin-eligible participants who were not taking statins had a higher prevalence of cardiovascular risk factors compared with statin-eligible participants who were taking statins. There was no significant increase in statin eligibility when atherosclerotic cardiovascular disease risk was calculated by using black estimates instead of recommended white estimates (increase by 1.4%, P =0.12) for Hispanic/Latinos., Conclusions: The eligibility of statin therapy increased consistently across all Hispanic/Latinos subgroups under the 2013 ACC/AHA guidelines and therefore will potentially increase the number of undertreated Hispanic/Latinos in the United States., (© 2017 The Authors.

Introduction: Female sex is a risk factor for heart failure with preserved ejection fraction (HFpEF). Previous literature suggests that some diastolic dysfunction (DD) develops during pregnancy and may persist postdelivery. Our objective was to examine the relationship between parity and cardiac structure and function in a population-based cohort., Methods: Participants included 1172 Hispanic/Latina women, aged ≥45 years, enrolled in the Echocardiographic Study of Latinos from four US communities (Bronx, Miami, San Diego and Chicago). Standard echocardiographic techniques were used to measure cardiac volumes, left ventricular mass, systolic and diastolic function. Using sampling weights and survey statistics, multivariable linear and logistic regression models were constructed adjusting for age, body mass index, diabetes or prediabetes, systolic blood pressure, use of antihypertensive medications, smoking, total cholesterol and high-density lipoprotein cholesterol., Results: In the target population, 5.0% were nulliparous (no live births) and 10.5% were grand multiparous (≥5 live births). Among the nulliparous women, 46% had DD as compared with 51%-58% of women with 1-4 live births and 81% of women with ≥5 live births (p<0.01). In full multivariate models, higher parity was significantly associated with greater left ventricular end-systolic volumes, end-diastolic volumes, left atrial volume indices and presence of DD (all p<0.01) but was not associated with ejection fraction. The log odds for having any grade of DD in grand-multiparous women was over three times that seen in nulliparous women (OR=3.4, 95% CI 1.5 to 7.9, p<0.01) in models further adjusted for income and education., Conclusions: Higher parity is associated with increased cardiac mass, volumes and the presence of DD. Further studies are needed to elucidate this apparent deleterious relation and whether parity can help explain the increased risk of HFpEF in women., Competing Interests: Competing interests: None declared.

Background: We examined the relationship between glucose homeostasis and comprehensive measures of cardiac structure and function among a representative sample of US Hispanics., Methods and Results: ECHO-SOL (Echocardiographic Study of Latinos), an echocardiographic ancillary study of the HCHS/SOL (Hispanic Community Health Study/Study of Latinos), enrolled 1818 Hispanic/Latino men (43%) and women (57%) aged ≥45 years (mean=56). Glucose intolerance was defined as follows: (1) prediabetes: hemoglobin (HbA1c) ≥5.7 and <6.5% and (2) diabetes mellitus: fasting plasma glucose ≥126 mg/dL, 2-hour postload glucose ≥200 mg/dL, HbA1c ≥6.5%, or hypoglycemic agent use. Uncontrolled diabetes mellitus was defined as HbA1c ≥7.0%. Insulin resistance was defined using the homeostatic model assessment for insulin resistance. Echocardiography examinations assessed left ventricular structure and systolic/diastolic function. Multivariable linear and logistic regression models were used. Prediabetes prevalence was 42%, and diabetes mellitus prevalence was 28% (47% uncontrolled). Glucose intolerance was associated with increased left ventricular posterior wall and interventricular septal and relative wall thicknesses (all P<0.05), reduced ejection fraction (P<0.01), reduced stroke and end-diastolic volumes (both P<0.001), decreased peak E' velocity (lateral and septal P<0.001), and increased E/E' ratio (lateral and septal P<0.01). The odds ratios (95% confidence intervals) for diastolic dysfunction among individuals with prediabetes and diabetes mellitus (versus diabetes mellitus free) were 1.36 (0.96-1.9) and 1.90 (1.3-2.8), respectively(P=0.006). Results were consistent for uncontrolled diabetes mellitus versus diabetes mellitus. Homeostatic model assessment for insulin resistance was associated with increased E/E' (P<0.001), and greater relative wall thickness and septal thickness (both P<0.05); lower stroke volume (P<0.0001); and lower peak lateral and septal E' velocities (both P<0.01)., Conclusions: Glucose intolerance and insulin resistance are associated with unfavorable cardiac structure and function, particularly worsened measures of diastolic function, even before the development of diabetes mellitus., (© 2016 American Heart Association, Inc.)

The effect of dietary isoflavone intake on systolic blood pressure (SBP) has not been studied in a large community-based cohort inclusive of African Americans. The authors analyzed data from the year 20 examination of the Coronary Artery Risk Development in Young Adults (CARDIA) study, including medical history, physical examination, and dietary intake surveys for 3142 participants. Multivariable linear regression models controlled for age, sex, body mass index, smoking, physical activity, and intakes of alcohol and total energy. Effect modification by race was tested. Overall, patients with hypertension had a lower daily intake of total dietary isoflavones (2.2±5.2 mg/d vs 4.1±11.7 mg/d; P<.001). In fully adjusted models, the highest quartile of dietary isoflavone intake was associated with a 4.4 mm Hg lower SBP on average compared with SBP for the lowest quartile. The relationship between dietary isoflavone intake and SBP was more pronounced among African Americans compared with Caucasians (P for interaction <.001). Greater dietary intake of isoflavones was independently associated with a lower SBP., (© 2015 Wiley Periodicals, Inc.)

Background: Population-based estimates of cardiac dysfunction and clinical heart failure (HF) remain undefined among Hispanics/Latino adults., Methods and Results: Participants of Hispanic/Latino origin across the United States aged 45 to 74 years were enrolled into the Echocardiographic Study of Latinos (ECHO-SOL) and underwent a comprehensive echocardiography examination to define left ventricular systolic dysfunction (LVSD) and left ventricular diastolic dysfunction (LVDD). Clinical HF was defined according to self-report, and those with cardiac dysfunction but without clinical HF were characterized as having subclinical or unrecognized cardiac dysfunction. Of 1818 ECHO-SOL participants (mean age 56.4 years; 42.6% male), 49.7% had LVSD or LVDD or both. LVSD prevalence was 3.6%, whereas LVDD was detected in 50.3%. Participants with LVSD were more likely to be males and current smokers (all P<0.05). Female sex, hypertension, diabetes mellitus, higher body mass index, and renal dysfunction were more common among those with LVDD (all P<0.05). In age-sex adjusted models, individuals of Central American and Cuban backgrounds were almost 2-fold more likely to have LVDD compared with those of Mexican backgrounds. Prevalence of clinical HF with LVSD (HF with reduced EF) was 7.3%; prevalence of clinical HF with LVDD (HF with preserved EF) was 3.6%. 96.1% of the cardiac dysfunction seen was subclinical or unrecognized. Compared with those with clinical cardiac dysfunction, prevalent coronary heart disease was the only factor independently associated with subclinical or unrecognized cardiac dysfunction (odds ratio: 0.1; 95% confidence interval: 0.1-0.4)., Conclusions: Among Hispanics/Latinos, most cardiac dysfunction is subclinical or unrecognized, with a high prevalence of diastolic dysfunction. This identifies a high-risk population for the development of clinical HF., (© 2016 American Heart Association, Inc.)

Background: Reference limits for echocardiographic quantification of cardiac chambers in Hispanics are not well studied., Methods and Results: We examined the reference values of left atrium and left ventricle (LV) structure in a large ethnically diverse Hispanic cohort. Two-dimensional transthoracic echocardiography was performed in 1818 participants of the Echocardiographic Study of Latinos (ECHO-SOL). Individuals with body mass index ≥30 kg/m(2), hypertension, diabetes mellitus, coronary artery disease, and atrial fibrillation were excluded leaving 525 participants defined as healthy reference cohort. We estimated 95th weighted percentiles of LV end systolic volume, LV end diastolic volume, relative wall and septal thickness, LV mass, and left atrial volume. We then used upper reference limits of the 2005 and 2015 American Society of Echocardiography (ASE) and 95th percentile of reference cohort to classify the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) target population into abnormal and normal. Reference limits were also calculated for each of 6 Hispanic origins. Using ASE 2015 defined reference values, we categorized 7%, 21%, 57%, and 17% of men and 18%, 29%, 60%, and 26% of women as having abnormal LV mass index, relative, septal, and posterior wall thickness, respectively. Conversely, 10% and 11% of men and 4% and 2% of women were classified as having abnormal end-diastolic volume and internal diameter by ASE 2015 cutoffs, respectively. Similar differences were found when we used 2005 ASE cutoffs. Several differences were noted in distribution of cardiac structure and volumes among various Hispanic/Latino origins. Cubans had highest values of echocardiographic measures, and Central Americans had the lowest., Conclusions: This is the first large study that provides normal reference values for cardiac structure. It further demonstrates that a considerable segment of Hispanic/Latinos residing in the United States may be classified as having abnormal measures of cardiac chambers when 2015 and 2005 ASE reference cutoffs are used., (© 2015 American Heart Association, Inc.)

How African American hair fragility relates to hair care practices and biologic differences between races is not well understood. To assess the differences between perceptions of hair health, hair care practices, and several biologic hair parameters between Caucasian and African American women. A questionnaire on perceptions of hair health and hair care practices was administered. Biological and structural parameters of hair shaft and scalp, including growth, density, diameter, cycle, breakage, and scalp blood flow were also assessed in this case-control study. Significant differences between the Caucasian and African American women were observed in the questionnaire and biologic study data. Regarding self-reported perceptions of hair health, there were differences in the following: hair shaft type (P < 0.001), hair breakage (P = 0.040), and desire to change hair (P = 0.001). Regarding self-reported hair care practices, there were differences in the following: location of haircutting (P = 0.002) and washing (P = 0.010), washing frequency (P < 0.001), chemical relaxer use (P < 0.001), hooded hair dryer use (P < 0.001), and hair shaft conditioner use (P = 0.005). The two groups had similar practices in regard to the use of hair color, frequency of hair color use, chemical curling agents, and handheld blow dryer use. Regarding biological and structural parameters, there were differences in the following: hair growth rate (P < 0.001), density (P = 0.0016), diameter (P = 0.01), number of broken hairs (P < 0.001), and blood flow (P = 0.03). There was no significant difference in hair cycle parameters.The differences in hair care practices and hair fiber morphology among African American women may contribute to clinically observed variation in hair fragility and growth., (© 2015 Wiley Periodicals, Inc.)

Background: We assessed high cholesterol (HC) awareness, treatment, and control rates among US Hispanic/Latino adults and describe factors associated with HC awareness and management., Methods and Results: Baseline data (collected 2008-2011) from a multisite probability sample of Hispanic/Latino adults in the Hispanic Community Health Study/Study of Latinos (18 to 74 years old; N=16 207) were analyzed. HC was defined as low-density lipoprotein-cholesterol ≥130 mg/dL and/or total cholesterol ≥240 mg/dL or use of cholesterol-lowering medication. Among Hispanic/Latino adults with HC, almost half (49.3%) were not aware of their condition and only 29.5% were receiving treatment. Men had a higher HC prevalence than women (44.0% versus 40.5%) but a lower rate of treatment (28.1% versus 30.6%). Younger adults were significantly less likely to be HC aware compared to those who were older. Those with hypertension, diabetes, and high socioeconomic position were more likely to be HC aware. US-born Hispanic/Latino were more likely to be HC unaware than foreign-born Hispanics/Latinos, but longer US residency was significantly associated with being HC aware, treated, and controlled. Cholesterol control was achieved among 64.3% of those who were HC treated. However, younger adults, women, those with lower income, those uninsured, and more recent immigrants were less likely to be HC controlled. Individuals of Puerto Rican or Dominican background were most likely to be HC aware and treated, whereas those of Mexican or Central American background were least likely to be HC treated. Individuals of Cuban and South American background had the lowest rates of HC control, whereas Puerto Ricans had the highest., Conclusions: Understanding gaps in HC awareness, treatment, and control among US Hispanic/Latino adults can help inform physicians and policymakers to improve disease management and patient education programs., (© 2015 The Authors.

Purpose: We studied incident atrial fibrillation (AF) in the prospective community-based Multi-Ethnic Study of Atherosclerosis (MESA). Reportedly, non-Hispanic blacks (NHBs) have a lower AF burden compared with their non-Hispanic white (NHW) counterparts. Information on the epidemiology of AF in Hispanic and Asian populations is much more limited., Methods: We excluded participants with a history of AF at enrollment. A total of 6721 MESA participants were monitored for the first AF event ascertained according to hospital discharge International Classification of Diseases, Ninth Revision, codes. Age- and sex-adjusted incidence rates (IRs) of AF were calculated per 1000 person-years of observation. IR ratios were calculated using NHWs as the reference group. Age- and sex-adjusted population attributable fractions (PAFs) of established modifiable AF risk factors were ascertained., Results: In the MESA cohort, 47.2% was male; at baseline, 25.7% had hypertension; 12.5% had diabetes. Three hundred five incident hospitalized AF events occurred over a mean follow-up of 7.3 years. Age- and sex-adjusted IRs and IR ratios showed that overall AF incidence was significantly lower among Hispanics, NHBs and Chinese compared with NHWs (all P < .001). Among participants 65 years of age or greater, Hispanics, Chinese, and blacks had significantly lower AF incidence than NHWs (all P ≤ .01), but IRs were similar among participants under age 65 years. The PAF for smoking was 27% among NHBs but lower among other race-ethnic groups. Among NHWs, the PAF for hypertension was 22.2%, but this was higher among NHBs (33.1%), Chinese (46.3%), and Hispanics (43.9%)., Conclusions: Overall, the incidence of hospitalized AF was significantly lower in Hispanics, NHBs, and Chinese than in NHWs. A larger proportion of AF events appear to be attributable to hypertension among nonwhite populations compared with NHWs., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Background: Patients with central nervous system (CNS) malignancies represent an "at-risk" population for contracting influenza, particularly if they are receiving ongoing chemotherapy, radiation, and/or glucocorticoid treatment. The Centers for Disease Control endorses vaccination for these patients, although data are not available to indicate whether they mount an immunologic response adequate to achieve clinical protection., Methods: A pilot prospective cohort study was designed to evaluate the immunogenicity of the standard-dose trivalent inactivated influenza vaccine in patients with malignant CNS tumors. Baseline data collection included diagnosis, chemotherapy, timing of chemotherapy or radiation relative to vaccination, and glucocorticoid dose. Serum samples were collected at baseline, day 14, day 28, and month 3 following vaccination. Samples were tested using hemagglutinin inhibition to determine seroconversion (4-fold rise in titer) and seroprotection (titer >1:40)., Results: A total of 38 patients were enrolled (mean age, 54 years ±13.5 years, 60.5% male, 94.7% Caucasian, and 5.3% African American). CNS tumor diagnoses included glioblastoma multiforme (55.2%), other high-grade glioma (13.2%), low-grade glioma (15.8%), and primary CNS lymphoma (15.8%). At enrollment, 20 patients (52.6%) were taking glucocorticoids, 25 (65.8%) were on active chemotherapy, and 3 (7.9%) were undergoing radiation. Seroconversion rates at day 28 for the A/H1N1, A/H3N2, and B strains were 37%, 23% and 23%, respectively. Seroprotection was 80%, 69%, and 74%, respectively. All rates were significantly lower than published rates in healthy adults (P < .001)., Conclusion: Influenza vaccine immunogenicity is significantly reduced in patients with CNS malignancies. Future studies are needed to determine the causative etiologies and appropriate vaccination strategies., (© The Author(s) 2014.

Background: The prevalence and determinants of dyslipidemia patterns among Hispanics/Latinos are not well known., Methods: Lipid and lipoprotein data were used from the Hispanic Community Health Study/Study of Latinos—a population-based cohort of 16,415 US Hispanic/Latinos ages 18-74 years. National Cholesterol Education Program cutoffs were employed. Differences in demographics, lifestyle factors, and biological and acculturation characteristics were compared among those with and without dyslipidemia., Results: Mean age was 41.1 years, and 47.9% were male. The overall prevalence of any dyslipidemia was 65.0%. The prevalence of elevated low-density lipoprotein cholesterol was 36.0%, and highest among Cubans (44.5%; P < .001). Low high-density lipoprotein cholesterol (HDL-C) was present in 41.4% and did not significantly differ across Hispanic background groups (P = .09). High triglycerides were seen in 14.8% of Hispanics/Latinos, most commonly among Central Americans (18.3%; P < .001). Elevated non-HDL-C was seen in 34.7%, with the highest prevalence among Cubans (43.3%; P < .001). Dominicans consistently had a lower prevalence of most types of dyslipidemia. In multivariate analyses, the presence of any dyslipidemia was associated with increasing age, body mass index, and low physical activity. Older age, female sex, diabetes, low physical activity, and alcohol use were associated with specific dyslipidemia types. Spanish-language preference and lower educational status were associated with higher dyslipidemia prevalence., Conclusion: Dyslipidemia is highly prevalent among US Hispanics/Latinos; Cubans seem particularly at risk. Determinants of dyslipidemia varied across Hispanic backgrounds, with socioeconomic status and acculturation having a significant effect on dyslipidemia prevalence. This information can help guide public health measures to prevent disparities among the US Hispanic/Latino population., (Copyright © 2014 Elsevier Inc. All rights reserved.)

The National Cancer Data Base (NCDB) of the American College of Surgeons gather demographic and survival data on ~70% of cancers in the USA. We wanted to investigate the demographic and survivorship data on this potentially more representative cohort of patients with soft tissue sarcomas. We selected 34 of the most commonly encountered soft tissue sarcomas reported to the NCDB, provided that each entity contained a minimum of 50 cases. This report summarizes the demographic and survivorship data on 63,714 patients with these 34 histologically distinct soft tissue sarcomas reported to the NCDB from 1998 to 2010. The overall survivorships of these sarcomas were near the lower limits of many prior reports due to the all-inclusive, minimally biased inclusion criteria. The overall best prognosis was Dermatofibrosarcoma NOS (not otherwise specified). (5-year survivorship 92%). The worst prognosis was Dedifferentiated Chondrosarcoma (5-year survivorship 19%). New observations included Biphasic Synovial Sarcoma demonstrating a better 5-year survivorship (65%) compared to spindle-cell synovial sarcoma (56%, P < 0.031) and Synovial Sarcoma, NOS (52%, P < 0.001). The demographic and 2- and 5-year survivorship data for all 34 soft tissue sarcomas are presented herein. This extent of demographic and survival data in soft tissue sarcomas is unprecedented. Because of the large number of cases and the inclusive nature of the NCDB, without restriction to certain stages, categories, or treatments, it is less subject to selection bias. Therefore, these data are thought to be more reflective of the true overall prognosis given the current management of sarcoma across the NCDB contributing sites., (© 2014 The Authors.

Importance: Studies document a progressive increase in heart disease risk as systolic blood pressure (SBP) rises above 115 mm Hg, but it is unknown whether an SBP lower than 120 mm Hg among adults with hypertension (HTN) lowers heart failure, stroke, and myocardial infarction risk., Objective: To examine the risk of incident cardiovascular (CV) events among adults with HTN according to 3 SBP levels: 140 mm Hg or higher; 120 to 139 mm Hg; and a reference level of lower than 120 mm Hg., Design, Setting, and Participants: A total of 4480 participants with HTN but without prevalent CV disease at baseline (years 1987-1989) from the Atherosclerosis Risk in Communities Study were included. Measurements of SBP were taken at baseline and at 3 triennial visits; SBP was treated as a time-dependent variable and categorized as elevated (≥140 mm Hg), standard (120-139 mm Hg), and low (<120 mm Hg). Multivariable Cox regression models included baseline age, sex, diabetes status, BMI, high cholesterol level, smoking status, and alcohol intake., Main Outcomes and Measures: Incident composite CV events (heart failure, ischemic stroke, myocardial infarction, or death related to coronary heart disease)., Results: After a median follow-up of 21.8 years, a total of 1622 incident CV events had occurred. Participants with elevated SBP developed incident CV events at a significantly higher rate than those in the low BP group (adjusted hazard ratio [HR], 1.46; 95% CI, 1.26-1.69). However, there was no difference in incident CV event-free survival among those in the standard vs low SBP group (adjusted HR, 1.00; 95% CI, 0.85-1.17). Further adjustment for BP medication use or diastolic BP did not significantly affect the results., Conclusions and Relevance: Among patients with HTN, having an elevated SBP carries the highest risk for cardiovascular events, but in this categorical analysis, once SBP was below 140 mm Hg, an SBP lower than 120 mm Hg did not appear to lessen the risk of incident CV events.

Background: The role of systemic chemotherapy (SC) in conjunction with cytoreductive surgery (CS) with hyperthermic intraperitoneal chemotherapy (HIPEC) in appendiceal mucinous carcinoma peritonei (MCP) is unknown., Methods: A retrospective review (1999-2011) of MCP patients who had undergone CS/HIPEC with or without perioperative SC., Results: Twenty-two low-grade MCP patients treated with CS/HIPEC and SC were matched to patients who received CS/HIPEC alone. Median overall survival (OS) was 107 months for patients treated with perioperative SC compared to 72 without (P = 0.46). CS/HIPEC was performed on 109 patients with high-grade MCP: 70 were treated with perioperative SC, while 39 were not. Median OS (22.1 vs. 19.6 months, P = 0.74) and progression-free survival (PFS) (10.9 vs. 7.0 months, P = 0.47) were similar in patients treated with SC compared to CS/HIPEC alone. Progression while on pre-operative SC was seen in eight patients (17%), while four (8%) had a partial response. Treatment with post-operative SC was associated with longer PFS (13.6 months) compared to pre-operative SC (6.8 months, P < 0.01) and CS/HIPEC alone (7.0 months, P = 0.03)., Conclusions: Post-operative SC appears to improve PFS in patients with high-grade appendiceal MCP treated with CS/HIPEC. In contrast, there is no evidence to support the routine use of perioperative SC in low-grade disease., (© 2013 Wiley Periodicals, Inc.)

Radical antegrade modular pancreatosplenectomy (RAMPS) has been reported to provide improved margin resection and lymph node retrieval for tumors of the body and tail of the pancreas compared with standard resection. We examined our experience with RAMPS and standard resection to determine differences in clinicopathologic outcomes. A comparison of RAMPS procedures was made to standard distal pancreatectomy and splenectomy examining various clinicopathologic variables through retrospective chart review. Twenty-six patients underwent distal pancreatectomy with or without splenectomy between November 2004 and June 2011. Twenty patients underwent standard resection and six patients underwent RAMPS procedures for a variety of histologies. As a result of the heterogeneity of diseases, which included benign lesions, margin status was not applicable in some cases and therefore was not assessed overall. Fisher's exact test and Wilcoxon rank sum tests demonstrated a significant difference in number of lymph nodes removed with mean of 4.3 and 11.2 lymph nodes obtained for standard resection and RAMPS, respectively (P = 0.03). The RAMPS procedure for lesions of the body and tail of the pancreas retrieved significantly more lymph nodes than standard distal pancreatectomy and splenectomy. It should be the preferred surgical approach when lymph node count is important for tumor staging.

Little is known about the neural correlates of expository text comprehension. In this study, we sought to identify neural networks underlying expository text comprehension, how those networks change over the course of comprehension, and whether information central to the overall meaning of the text is functionally distinct from peripheral information. Seventeen adult subjects read expository passages while being scanned using functional magnetic resonance imaging (fMRI). By convolving phrase onsets with the hemodynamic response function (HRF), we were able to identify regions that increase and decrease in activation over the course of passage comprehension. We found that expository text comprehension relies on the co-activation of the semantic control network and regions in the posterior midline previously associated with mental model updating and integration [posterior cingulate cortex (PCC) and precuneus (PCU)]. When compared to single word comprehension, left PCC and left Angular Gyrus (AG) were activated only for discourse-level comprehension. Over the course of comprehension, reliance on the same regions in the semantic control network increased, while a parietal region associated with attention [intraparietal sulcus (IPS)] decreased. These results parallel previous findings in narrative comprehension that the initial stages of mental model building require greater visuospatial attention processes, while maintenance of the model increasingly relies on semantic integration regions. Additionally, we used an event-related analysis to examine phrases central to the text's overall meaning vs. peripheral phrases. It was found that central ideas are functionally distinct from peripheral ideas, showing greater activation in the PCC and PCU, while over the course of passage comprehension, central and peripheral ideas increasingly recruit different parts of the semantic control network. The finding that central information elicits greater response in mental model updating regions than peripheral ideas supports previous behavioral models on the cognitive importance of distinguishing textual centrality.

Background: Defining dispersal of influenza virus via aerosol is essential for the development of prevention measures., Methods: During the 2010-2011 influenza season, subjects with influenza-like illness were enrolled in an emergency department and throughout a tertiary care hospital, nasopharyngeal swab specimens were obtained, and symptom severity, treatment, and medical history were recorded. Quantitative impaction air samples were taken not ≤0.305 m (1 foot), 0.914 m (3 feet), and 1.829 m (6 feet) from the patient's head during routine care. Influenza virus was detected by rapid test and polymerase chain reaction., Results: Sixty-one of 94 subjects (65%) tested positive for influenza virus. Twenty-six patients (43%) released influenza virus into room air, with 5 (19%) emitting up to 32 times more virus than others. Emitters surpassed the airborne 50% human infectious dose of influenza virus at all sample locations. Healthcare professionals (HCPs) were exposed to mainly small influenza virus particles (diameter, <4.7 µm), with concentrations decreasing with increasing distance from the patient's head (P < .05). Influenza virus release was associated with high viral loads in nasopharyngeal samples (shedding), coughing, and sneezing (P < .05). Patients who reported severe illness and major interference with daily life also emitted more influenza virus (P < .05)., Conclusions: HCPs within 1.829 m of patients with influenza could be exposed to infectious doses of influenza virus, primarily in small-particle aerosols. This finding questions the current paradigm of localized droplet transmission during non-aerosol-generating procedures.

Background: Cytoreductive surgery (CS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is the treatment most likely to achieve prolonged survival in peritoneal carcinomatosis (PC). Yet the efficacy of HIPEC in rectal patients is controversial because of the retroperitoneal location of the primary tumor. Therefore, we reviewed our experience in patients with PC from a rectal primary tumor., Methods: A retrospective analysis of a prospective database of 950 HIPEC procedures was performed. Performance status, age, albumin level, prior surgical score, resection status, morbidity, mortality, and survival were reviewed., Results: A total of 13 and 204 patients with PC from rectal and colon cancer, respectively, were identified. Median follow-up was 40.1 and 88.1 months, respectively. Eastern Cooperative Oncology Group (ECOG) score was zero or one for 92 % of patients with rectal cancer and 83 % for colon, while R1 resection was achieved in 54 and 51 %. The 30-day mortality was 5 % for colon cancer. There were no deaths in the rectal group. The morbidity for the colon and rectal groups was 57 and 46 %, respectively, with a 23 % 30-day readmission rate. In univariate analysis, age, ECOG, prior surgical score, albumin level, and node and resection status were not statistically significant in predicting survival for the rectal cancer patients. Median survival for the rectal and colon groups was 14.6 versus 17.3 months, while the 3-year survival was 28.2 versus 25.1 %., Conclusions: Our data demonstrate similar 3-year survival for patients with rectal and colon cancer PC treated with CS/HIPEC. This can be attributed to patient selection bias. Selected rectal cancer PC patients should not be excluded from an attempted cytoreduction and HIPEC.

Objective: To characterize the influence of hair style maintenance on exercise behavior in African American women., Design: A 40-item survey with questions concerning hair care practices, physical activity, and the relationship between the two., Setting: University-affiliated dermatology department at an academic medical center in Winston-Salem, North Carolina., Participants: A total of 123 African American women from 21 to 60 years of age were surveyed; 103 women completed the questionnaire., Main Outcome Measures: The statistical significance of relationships between hair care practices and physical activity was determined., Results: Fifty percent of African American women surveyed have modified their hair style to accommodate exercise and nearly 40% (37.9%) avoid exercise at times owing to hair-related issues. Respondents who exercised less owing to hair concerns were 2.9 times less likely to exercise more than 150 min/wk (95% CI,0.9-9.4; P=.08)., Conclusion: Dermatologists can discuss hair management strategies during exercise that facilitate routinely performing exercise.

Over the past 30 years, the treatment of metastatic colorectal cancer to the liver has undergone major changes. Once considered terminal and incurable, the prognosis of patients with colorectal hepatic metastases has seen dramatic improvements using modern multimodality therapy and now long-term survival and even cure are possible in some patients. Despite the advances seen in systemic therapy, hepatic resection offers the longest survival potential and remains the only curative option. Based on long-term outcomes and the improved safety of hepatic resection using modern operative techniques and critical care support, an aggressive locoregional approach to colorectal hepatic metastasis has become the standard of care. This article focuses on the management of colorectal hepatic metastases and highlights the importance of multimodality therapy. We also report our 18-year experience treating patients with hepatic resection for colorectal metastases.
