Evaluation of the Lung Cancer Risks at Which to Screen Ever- and Never-Smokers: Screening Rules Applied to the PLCO and NLST Cohorts

BackgroundLung cancer risks at which individuals should be screened with computed tomography (CT) for lung cancer are undecided. This study''s objectives are to identify a risk threshold for selecting individuals for screening, to compare its efficiency with the U.S. Preventive Services Task Force (USPSTF) criteria for identifying screenees, and to determine whether never-smokers should be screened. Lung cancer risks are compared between smokers aged 55–64 and ≥65–80 y.ConclusionsThe USPSTF criteria for CT screening include some low-risk individuals and exclude some high-risk individuals. Use of the PLCO_m2012 risk ≥0.0151 criterion can improve screening efficiency. Currently, never-smokers should not be screened. Smokers aged ≥65–80 y are a high-risk group who may benefit from screening. Please see later in the article for the Editors'' Summary     

Hemoglobin A1C Criterion for Diabetes Diagnosis Among Hispanic and Non-Hispanic Populations

ObjectiveTo report on the performance of the recently recommended hemoglobin A1c (A1C) criterion for diabetes diagnosis in comparison with the standard fasting plasma glucose and 2-hour post-glucose challenge (PG) test criteria across racial and ethnic groups.MethodsWe evaluated local and national survey data from 689 Dominican, 4, 862 Hispanic, 4, 694 African American, and 6, 883 white study subjects. We compared rates of diabetes classification by diagnostic criteria, agreement and disagreement between A1C and PG criteria for diagnosing diabetes, and differences in cardiometabolic risk among the 3 diagnostic groups across racial and ethnic stratifications.ResultsThe A1C-based diabetes diagnoses were higher among Dominican and African American study subjects (81.6% and 67.0%, respectively), and lower among Hispanic and white subjects (46.0% and 37.9%, respectively). Among those not meeting any PG criterion for diabetes, the A1C criterion identified diabetes in 8.3% of Dominican, 3.5% of African American, 0.9% of Hispanic, and 0.5% of white study subjects. The A1C criterion, however, did not identify diabetes in 64.5% of white, 46.1% of Dominican, 44.0% of African American, and 41.9% of Hispanic subjects who were diagnosed with diabetes by a PG criterion. For single tests, the agreement was greatest between A1C and fasting plasma glucose test criteria among Dominican, Hispanic, and African American study populations—76.9%, 65.6%, and 60.7%, respectively. There was no clear difference in selected cardiometabolic risks between A1C and PG-only diabetes diagnoses across racial and ethnic groups.ConclusionThe A1C criterion yields racialand ethnic-specific differences in diagnosing diabetes and in test agreements with PG-based criteria. Furthermore, diagnostic differences were observed between the Dominican subgroup and the Hispanic study population, of whom 91.5% were Mexican American. (Endocr Pract. 2011;17: 210-217)     

Determinants of racial/ethnic differences in blood pressure management among hypertensive patients

Background

Prior literature has shown that racial/ethnic minorities with hypertension may receive less aggressive treatment for their high blood pressure. However, to date there are few data available regarding the confounders of racial/ethnic disparities in the intensity of hypertension treatment.

Methods

We reviewed the medical records of 1,205 patients who had a minimum of two hypertension-related outpatient visits to 12 general internal medicine clinics during 7/1/01-6/30/02. Using logistic regression, we determined the odds of having therapy intensified by patient race/ethnicity after adjustment for clinical characteristics.

Results

Blacks (81.9%) and Whites (80.3%) were more likely than Latinos (71.5%) to have therapy intensified (P = 0.03). After adjustment for racial differences in the number of outpatient visits and presence of diabetes, there were no racial differences in rates of intensification.

Conclusion

We found that racial/ethnic differences in therapy intensification were largely accounted for by differences in frequency of clinic visits and in the prevalence of diabetes. Given the higher rates of diabetes and hypertension related mortality among Hispanics in the U.S., future interventions to reduce disparities in cardiovascular outcomes should increase physician awareness of the need to intensify drug therapy more agressively in patients without waiting for multiple clinic visits, and should remind providers to treat hypertension more aggressively among diabetic patients.     

Improving Ambulatory Diabetes Care In High-Risk Racial Minorities:Use Of Culture-Specific Education And Close Follow-Up

ObjectiveTo describe a project aimed at improving diabetes care in the ambulatory setting among 2 high-risk racial minorities (African American and Hispanic patients) by using culture-specific education provided by trained diabetes educators from the same racial groups as the targeted patients.MethodsTwo nurse educators, 1 Hispanic and 1 African American, completed a standardized chronic disease management program, as did 2 patients with diabetes from each of the aforementioned ethnic groups in preparation for training other patients. The study patients participated in group classes or one-on-one sessions to learn about appropriate management of their diabetes, related complications, and improved lifestyle habits. Close follow-up by telephone and regular appointments ensured that appropriate glucose monitoring and laboratory tests were performed. Outcome measures before and after the intervention were recorded, with final project follow-up at 24 months. A control group was identified during the same period, which received standard care (follow-up with a physician every 3 to 6 months).ResultsAn improvement in control of diabetes occurred, as determined by a significant decline in hemoglobin A1c levels in both minority study groups. Emergency department visits also decreased significantly.Lipid profiles and microalbumin showed improvement as well. More than 90% of patients kept appointments and had all laboratory studies performed.Conclusion: The project intervention had a notable effect, physically and psychologically, on the 2 ethnic sample populations studied. These results have major implications, both clinically and financially, for public health policy planning for diabetes care in minority populations. (Endocr Pract 2010;16:171-177)     

Racial disparities in incidence of human papillomavirus-associated oropharyngeal cancer in an urban population

BackgroundRecent studies suggest that rates of human papillomavirus related oropharyngeal cancer (HPVOPC) in the US are higher in Caucasians than minorities. We hypothesized that this disparity would be less marked in a racially and ethnically diverse population from New York City.MethodsThis is a retrospective chart review of 210 patients with biopsied or surgically treated OPC at the Icahn School of Medicine at Mount Sinai (ISMMS) between 1999 and 2013. Polymerase chain reaction (PCR) was used to detect the presence of HPV-DNA in paraffin-embedded tumor blocks. Incidence of HPV-positive cancers was compared between Caucasians and minorities (defined as African Americans, Asians, and Hispanics) using Fisher’s exact test.ResultsWe found a higher incidence of HPV-positive OPC in Caucasians than racial minorities within the ISMMS population (p = 0.002). HPV incidence detected by PCR was 139/165 [84.2%] for Caucasians and 28/45 [62.2%] for minorities. Specifically, there was a higher rate in Caucasians compared to African Americans (p = 0.017), but no significant difference between Caucasians and Hispanics (p = 0.087).ConclusionWe documented a disparity in incidence of HPVOPC amongst racial groups, consistent with previously reported trends from study populations in less urbanized areas. Thus we conclude that the factors underlying racial/ethnic disparities in HPVOPC incidence are likely to be similar across communities with different levels of urbanization and population diversity.     

Receipt of Glucose Testing and Performance of Two US Diabetes Screening Guidelines, 2007–2012

Background

Screening guidelines are used to help identify prediabetes and diabetes before implementing evidence-based prevention and treatment interventions. We examined screening practices benchmarking against two US guidelines, and the capacity of each guideline to identify dysglycemia.

Methods

Using 2007–2012 National Health and Nutrition Examination Surveys, we analyzed nationally-representative, cross-sectional data from 5,813 fasting non-pregnant adults aged ≥20 years without self-reported diabetes. We examined proportions of adults eligible for diagnostic glucose testing and those who self-reported receiving testing in the past three years, as recommended by the American Diabetes Association (ADA) and the US Preventive Services Task Force (USPSTF-2008) guidelines. For each screening guideline, we also assessed sensitivity, specificity, and positive (PPV) and negative predictive values in identifying dysglycemia (defined as fasting plasma glucose ≥100 mg/dl or hemoglobin A1c ≥5.7%).

Results

In 2007–2012, 73.0% and 23.7% of US adults without diagnosed diabetes met ADA and USPSTF-2008 criteria for screening, respectively; and 91.5% had at least one major risk factor for diabetes. Of those ADA- or USPSTF-eligible adults, about 51% reported being tested within the past three years. Eligible individuals not tested were more likely to be lower educated, poorer, uninsured, or have no usual place of care compared to tested eligible adults. Among adults with ≥1 major risk factor, 45.7% reported being tested, and dysglycemia yields (i.e., PPV) ranged from 45.8% (high-risk ethnicity) to 72.6% (self-reported prediabetes). ADA criteria and having any risk factor were more sensitive than the USPSTF-2008 guideline (88.8–97.7% vs. 31.0%) but less specific (13.5–39.7% vs. 82.1%) in recommending glucose testing, resulting in lower PPVs (47.7–54.4% vs. 58.4%).

Conclusion

Diverging recommendations and variable performance of different guidelines may be impeding national diabetes prevention and treatment efforts. Efforts to align screening recommendations may result in earlier identification of adults at high risk for prediabetes and diabetes.     

Potential impact of the Affordable Care Act's preventive services provision on breast cancer stage: A preliminary assessment

IntroductionThe Affordable Care Act's (ACA) preventive services provision (PSP) removes copayments for preventive services such as cancer screening. We examined: 1) whether a shift in breast cancer stage occurred, and 2) the impact of the provision on racial/ethnic disparities in stage.Materials and methodsData from the National Cancer Database were used. The pre- and post-PSP periods were identified as 2007–2009 and 2011–2013, respectively. Proportion differences (PDs) and 95% confidence Intervals (CIs) were calculated.ResultsAll three racial/ethnic groups experienced a statistically significant shift toward Stage I breast cancer. Pre-PSP, the black:white disparity in Stage I cancer was −9.5 (95% CI: −8.9, −10.4) and the Latina:white disparity was −5.2 (95% CI: −4.0, −6.1). Post-PSP, the disparities improved slightly.DiscussionPreliminary data suggest that the ACA's PSP may have a meaningful impact on cancer stage overall and by race/ethnicity. However, more time may be needed to see reductions in disparities.     

When markets blink: US stock price responses to the appointment of minority leaders

This study examines whether the appointment of racial/ethnic minorities into top management positions has a different impact on share price than the appointment of members of the racial/ethnic majority into equivalent positions. Our dependent variable is the degree of change in share price following the announcement of minority and majority men into senior management positions. Market reaction to the naming of minorities into corporate leadership positions is significant and negative while the market's reaction to the naming of members of the racial/ethnic majority is significant and positive. Our findings suggest that racial/ethnic integration of corporate hierarchies may be impeded as investor reaction increasingly drives firm-level governance decisions.     

Effectiveness of patient-targeted interventions to promote cancer screening among ethnic minorities: A systematic review

BackgroundCancer is a major public health problem due to its incidence, morbidity and mortality. A large proportion of cancer cases and deaths could be prevented through the implementation of cancer screening programmes. However, there are social inequalities in patient access to these programmes, especially in underserved communities and minority populations.ObjectiveTo identify, characterise and analyse the effectiveness of patient-targeted healthcare interventions to promote cancer screening programmes in ethnic minorities.MethodsA comprehensive search of bibliographic databases was conducted. The results of our systematic review were reported in accordance with the PRISMA guidelines.ResultsSeventeen articles were identified and included in the review. Sixteen of the seventeen studies were conducted in the United States and one was conducted in Israel. Fifteen of the seventeen interventions selected were effective in increasing cancer screening rates. Moreover, five of the seventeen studies found an improvement in cancer knowledge, awareness, self-efficacy, attitudes, intention and perceptions, and three studies found a positive change in health beliefs and barriers. The results show that culturally adapted interventions appear to increase the rate of participation in cancer screening. In addition, the effectiveness of the interventions seems to be related to the use of small media, one-on-one interactions, small group education sessions, reminder strategies, and strategies for reducing structural barriers and out-of-pocket costs.ConclusionCulturally adapted patient-targeted healthcare interventions can help to reduce racial or ethnic inequalities in access to cancer screening programmes. Further research is needed to develop interventions to promote adherence to cancer screening programmes with repeat testing and vigorous economic evaluation methodologies.     

Revised Case Finding Protocol for Dysglycemia in Chile: A Call for Action in Other Populations

ObjectiveGuidelines recommend case finding for dysglycemia (prediabetes and type 2 diabetes [T2D]) in adults or youth older than 10 years with overweight/obesity, but increased adiposity has not been associated with dysglycemia in some Hispanic populations. This study aims to determine the prevalence of dysglycemia in this population using simplified criteria independent of body mass index and age to request an oral glucose tolerance test (OGTT).MethodsCross-sectional retrospective analysis of medical records from a clinical center in Chile (2000-2007). OGTT was obtained from any patient with 1 cardiometabolic risk factor (CMRF) independent of age and body mass index.ResultsIn total, 4969 adults (mean age ± SD) 45.7 ± 15.9 years and 509 youths 16.6 ± 3.0 years were included. The prevalence (%, 95% CI) of prediabetes doubled that of T2D in youths (14.1%, 1.4-17.4 vs 6.3%, 4.5-8.7) and tripled it in adults (36.0%, 34.7-37.4 vs 10.7%, 9.8-11.5). In underweight and normal-weight adults, 22% (12.0-36.7) and 29.2% (26.4-32.1) had prediabetes, whereas 4.9% (1.3-16.1) and 8.8% (7.2-10.7) had T2D, respectively. In normal weight youths, 10.5% (6.7-15.9) and 2.9% (1.2-6.6) had prediabetes and T2D, respectively. In adults, but not in youths, most dysglycemia categories were related to overweight/obesity.ConclusionThis study supports a public health policy to identify more people at risk for cardiovascular disease by implementing a revised case finding protocol for dysglycemia using OGTT in even normal weight patients over 6 years of age when there is at least 1 CMRF. Reanalysis of case finding protocols for cardiometabolic risk in other populations is warranted.     

Endocrine Follow-up During Post-Acute COVID-19: Practical Recommendations Based on Available Clinical Evidence

ObjectiveCOVID-19 affects multiple endocrine organ systems during the disease course. However, follow-up data post-COVID-19 is scarce; hitherto available limited data suggest that most of the biochemical endocrine dysfunctions observed during acute phase of COVID-19 tend to improve after recovery. Hence, we aim to provide a rational approach toward endocrine follow-up of patients during post-acute COVID-19.MethodsWe performed a literature review across PubMed/MEDLINE database looking into the effects of COVID-19 on endocrine system and subsequent long-term endocrine sequelae. Accordingly, we have presented a practical set of recommendations regarding endocrine follow-up post-acute COVID-19.ResultsCOVID-19 can lead to new-onset hyperglycemia/diabetes mellitus or worsening of dysglycemia in patients with preexisting diabetes mellitus. Hence, those with preexisting diabetes mellitus should ensure optimum glycemic control in the post-COVID-19 period. New-onset diabetes mellitus has been described post-acute COVID-19; hence, a selected group of patients (aged <70 years and those requiring intensive care unit admission) may be screened for the same at 3 months. Thyroid dysfunction (euthyroid sick syndrome and atypical thyroiditis) and adrenal insufficiency have been described in COVID-19; however, thyroid/adrenal functions usually normalize on follow-up; hence, widespread screening post-acute COVID-19 should not be recommended. Pituitary apoplexy and male hypogonadism have rarely been documented in COVID-19; therefore, appropriate follow-up may be undertaken as per clinical context. Hypocalcemia during COVID-19 is not uncommon; however, routine estimation of serum calcium post-COVID-19 is not warranted.ConclusionThe recommendations herein provide a rational approach that would be expected to guide physicians to better delineate and manage the endocrine sequelae during post-acute COVID-19.     

Abdominal Obesity and Ethnic Differences in Diabetes Awareness,Treatment, and Glycemic Control

Objective: To compare racial/ethnic differences in diabetes awareness, treatment, and glycemic control between non-Hispanic white, non-Hispanic black, and Hispanic Americans. We also determined the impact of abdominal obesity on racial/ethnic differences in diabetes awareness, treatment, and glycemic control between these population groups. Research Methods and Procedures: Third National Health and Nutrition Examination Survey (NHANES III) data were utilized for this study. Diabetes awareness was defined as acknowledging diabetic status. Diabetes treatment was defined as current use of anti-diabetic medications, good glycemic control as HbA_1c < 8%, and abdominal obesity as waist circumference larger than expected. The impacts of abdominal obesity on racial/ethnic differences in diabetes awareness, treatment, and glycemic control were assessed using logistic regression analyses. Adjustments were made for age, education, smoking, alcohol intake, and health insurance. Results: Rates of diabetes awareness in whites, blacks, and Hispanics suffering from abdominal obesity were ∼74%, 30%, and 21% in men and 77%, 32%, and 19% in women, respectively. Rates of diabetes treatment were 70%, 23%, and 14% in men and 57%, 45%, and 23% in women, respectively. In men, rates of glycemic control were 64%, 40%, and 30%, and in women, they were 62%, 51%, and 27%, respectively. Abdominal obesity was associated with decreased diabetes awareness and glycemic control in women. Discussion: Subjects with abdominal obesity were found to have poorer glycemic controls compared to those without abdominal obesity. Because diabetes prevalences were partially explained by racial/ethnic differences in diabetes awareness, treatment, and glycemic control, there is a need to craft diabetes awareness, treatment, and control programs along racial/ethnic origins.     

American Indian/Alaska Native and black colon cancer patients have poorer cause-specific survival based on disease stage and anatomic site of diagnosis

ObjectivesStudies of race-specific colon cancer (CC) survival differences between right- vs. left-sided CC typically focus on Black and White persons and often consider all CC stages as one group. To more completely examine potential racial and ethnic disparities in side- and stage-specific survival, we evaluated 5-year CC cause-specific survival probabilities for five racial/ethnic groups by anatomic site (right or left colon) and stage (local, regional, distant).MethodsWe obtained cause-specific survival probability estimates from National Cancer Institute’s population-based Surveillance, Epidemiology, and End Results (SEER) for CC patients grouped by five racial/ethnic groups (Non-Hispanic American Indian/Alaska Native [AIAN], Non-Hispanic Asian/Pacific Islander [API], Hispanic, Non-Hispanic Black [NHB], and Non-Hispanic White [NHW]), anatomic site, stage, and other patient and SEER registry characteristics. We used meta-regression approaches to identify factors that explained differences in cause-specific survival.ResultsDiagnoses of distant-stage CC were more common among NHB and AIAN persons (>22 %) than among NHW and API persons (< 20 %). Large disparities in anatomic site-specific survival were not apparent. Those with right-sided distant-stage CC had a one-year cause-specific survival probability that was 16.4 % points lower (99 % CI: 12.2–20.6) than those with left-sided distant-stage CC; this difference decreased over follow-up. Cause-specific survival probabilities were highest for API, and lowest for NHB, persons, though these differences varied substantially by stage at diagnosis. AIAN persons with localized-stage CC, and NHB persons with regional- and distant-stage CC, had significantly lower survival probabilities across follow-up.ConclusionsThere are differences in CC presentation according to anatomic site and disease stage among patients of distinct racial and ethnic backgrounds. This, coupled with the reality that there are persistent survival disparities, with NHB and AIAN persons experiencing worse prognosis, suggests that there are social or structural determinants of these disparities. Further research is needed to confirm whether these CC cause-specific survival disparities are due to differences in risk factors, screening patterns, cancer treatment, or surveillance, in order to overcome the existing differences in outcome.     

Impact of Race/Ethnicity on the Efficacy and Safety of Commonly used Insulin Regimens: A Post HOC Analysis of Clinical Trials in Type 2 Diabetes Mellitus

ObjectiveTo explore the impact of race/ethnicity on the efficacy and safety of commonly used insulin regimens in patients with type 2 diabetes mellitus.MethodsIn this post hoc analysis, pooled data from 11 multinational clinical trials involving 1455 patients with type 2 diabetes were used to compare specific insulin treatments in Latino/Hispanic, Asian, African-descent, and Caucasian patients. Insulin treatments included once daily insulin glargine or neutral protamine Hagedorn (BASAL), insulin lispro mix 75/25 twice daily (LMBID), or insulin lispro mix 50/50 three times daily (LMTID).ResultsRace/ethnicity was associated with significant outcome differences for each of the insulin regimens. BASAL therapy was associated with greater improvement in several measures of glycemic control among Latino/Hispanic patients compared with Caucasian patients (lower end point hemoglobin A1c, greater reduction in hemoglobin A1c from baseline, and a larger proportion of patients achieving hemoglobin A1c level < 7%). In contrast, LMBID therapy was associated with higher end point hemoglobin A_1c and a smaller decrease in hemoglobin A_1c from baseline in Latino/Hispanic and Asian patients than in Caucasian patients. Furthermore, fewer Asian patients attained a hemoglobin A_1c level < 7% than did Caucasians patients. For LMTID therapy, hemoglobin A_1c outcomes were comparable across patient groups. Fasting blood glucose and glycemic excursions varied among racial/ethnic groups for the 3 insulin regimens. Weight change was comparable among racial/ethnic groups in each insulin regimen. During treatment with LMTID, Asian patients experienced higher incidence and rate of severe hypoglycemia than Caucasian patients.ConclusionsLatino/Hispanic, Asian, and African-descent patients with type 2 diabetes show different metabolic responses to insulin therapy, dependent in part on insulin type and regimen intensity.

Using Allostatic Load to Validate Self-rated Health for Racial/Ethnic Groups in the United States

This study evaluates the validity of subjective health measurement for racial/ethnic comparisons in the United States, by assessing whether allostatic load (AL) is equally associated with poor/fair self-rated health (SRH) for different racial/ethnic groups. This study used data from the National Health and Nutrition Survey (NHANES) for 2006–2010. Multivariable logistic regression models were fit and stratified by race/ethnicity to study the association between AL and poor/fair SRH. Higher levels of AL were associated with higher odds of reporting poor/fair SRH. However, this association differs by race/ethnicity. Analysis of interactions and racial/ethnic-stratified models suggest that AL is less associated with poor/fair SRH status for non-Hispanic Blacks and Hispanics populations. These results demonstrate that subjective health ratings potentially underestimate actual measures of biological health risk, especially for racial/ethnic minorities. As a result, population-based assessments of racial/ethnic health disparities based on SRH may be significantly understated.     

Sociocultural factors and the genetic diversification of Amazonian Indians: A brief overview

Abstract

Within SES categories in the United States, racial and ethnic minorities generally fare less well on a variety of health‐related indicators than do majority groups. Important differences exist within subgroups, however, and at present, these differences are poorly understood. In this paper we address Hispanic subgroup (Cuban American, Mexican American, Puerto Rican, and Central/South American) differences in utilization of prenatal care. Data from the 1986 and 1987 national Linked Birth/Infant Death files are used to assess patterns of prenatal care utilization across subgroups. Using Kotelchuck's Adequacy of Prenatal Care Utilization Index, we find that when controlling for other factors, Cuban American and Puerto Rican women are more likely to obtain adequate care than are Hispanic women of Mexican or Central/South American origin. Other factors important in understanding utilization patterns include marital status, education level, birthplace, and region of the country. We conclude with a discussion of the relatively weak link between prenatal care and birth outcomes and identify important cultural factors that may be important in understanding why this relationship is not stronger.     

Survival disparities for childhood cancers exist when defined by race/ethnicity and sex

BackgroundThere are documented racial/ethnic and sex differences in pediatric cancer survival; however, it is unknown whether pediatric cancer survival disparities exist when race/ethnicity and sex are considered jointly.MethodsUsing SEER data (2000–2017), we estimated survival differences by race/ethnicity within sexes and by sex within race/ethnicity (White, Black, Hispanic, and Asian/Pacific Islander [API]) for 17 cancers in children aged (0–19 years). Kaplan-Meier curves (Log-Rank p-values) were assessed. Cox regression was used to estimate hazards ratios (HRs) and 95 % confidence intervals (95 % CIs) between race/ethnicity/sex and cancer.ResultsWe included 51,759 cases (53.6 % male, 51.9 % White). There were statistically significant differences in 18-year survival by race/ethnicity-sex for 12/17 cancers. Within sexes, minorities had an increased risk of death compared to Whites for various cancers including acute lymphoblastic leukemia (ALL) (females: HispanicHR: 1.78, 95 % CI: 1.52, 2.10; BlackHR: 1.70, 95 % CI: 1.29, 2.24; APIHR: 1.42, 95 % CI: 1.07–1.89; males ALL: HispanicHR: 1.58, 95 % CI: 1.39,1.79; BlackHR: 1.57, 95 % CI: 1.26,1,95; API-HR: 1.39, 95 % CI: 1.11, 1.75) and astrocytoma (females: HispanicHR: 1.49, 95 % CI: 1.19, 1.85; BlackHR: 1.67, 95 % CI: 1.29, 2.17; API-HR: 1.51, 95 % CI: 1.05, 2.15; males: HispanicHR:1.27, 95 % CI: 1.04, 1.56; BlackHR: 1.69, 95 % CI: 1.32, 2.17; API-HR: 1.92, 95 % CI: 1.43, 2.58). Sex differences in survival within racial/ethnic groups were observed for White (ALL, osteosarcoma), Hispanic (medulloblastoma), and API (Primitive Neuro-Ectodermal Tumor [PNET]) children.ConclusionsThere are disparities in survival by both race/ethnicity and sex highlighting the societal and biologic influences these features have on survival in children with cancer.     

Dynamics of human populations

This study expands on earlier findings of racial/ethnic and education–allostatic load associations by assessing whether racial/ethnic differences in allostatic load persist across all levels of educational attainment. This study used data from four recent waves of the National Health and Nutrition Survey (NHANES). Results from this study suggest that allostatic load differs significantly by race/ethnicity and educational attainment overall, but that the race/ethnicity association is not consistent across education level. Analysis of interactions and education-stratified models suggest that allostatic load levels do not differ by race/ethnicity for individuals with low education; rather, the largest allostatic load differentials for Mexican Americans (p < .01) and non-Hispanic blacks (p < .001) are observed for individuals with a college degree or more. These findings add to the growing evidence that differences in socioeconomic opportunities by race/ethnicity are likely a consequence of differential returns to education, which contribute to higher stress burdens among minorities compared to non-Hispanic whites.     

Becoming American by becoming Muslim: strategic assimilation among second-generation Muslim American parents

ABSTRACT

Strategic assimilation describes how individuals use boundary work to construct identities which allow them to selectively maintain ties to a minority community while assimilating into the mainstream. However, scholarship that accounts for the role that minority religious identity plays in these processes is warranted. The current study fills a theoretical and empirical niche by exploring boundary work among not only racial, but religious minorities in their processes of identity construction and assimilation. Based on two years of ethnographic fieldwork as well as 72 in-depth interviews with Muslim Americans in Metro-Detroit, I demonstrate how upper-middle-class suburban second-generation parents actively deconstructed class, racial, and ethnic boundaries to construct boundaries around religious identity and generational identity. In so doing, they consciously crafted a de-ethnicized interpretation of Islam and hence a Muslim American identity that they saw as integral in promoting upward assimilation for themselves and their third-generation children.     

LDCT lung cancer screening eligibility and use of CT scans for lung cancer among sexual minorities

ObjectiveTo compare eligibility for lung cancer screening and receipt of a CT scan for lung cancer among sexual minorities.MethodsSecondary data analysis of cross-sectional data from older U.S. adults in the Behavioral Risk Factor Surveillance System survey during the 2017 cycle (n = 20,685).ResultsRates of eligibility for low-dose helical computed tomography (LDCT) were roughly twice as high among sexual minorities than among heterosexuals (21.1% vs. 11.7%). The odds of gay men and lesbian women indicating eligibility for LDCT screening were four to five times higher when compared to their heterosexual peers. No statistically significant differences were found between sexual minorities and heterosexuals with respect to having a CT scan for lung cancer in the past year.ConclusionsThere are potential sexual-identity-related disparities in the utilization of lung cancer screening among eligible smokers. Interventions are needed to increase awareness and uptake of lung cancer screening in order to detect and manage this common form of cancer in the U.S.
