Odds of developing cancer among male and female volunteer firefighters in Florida: A case-control study design.

OBJECTIVE: Determine whether volunteer firefighters in Florida are at increased odds of developing cancer compared to non-firefighters. METHODS: A case-control study design was implemented to assess the odds of developing cancer among male and female volunteer firefighters in Florida. Gender-specific age and calendar year-adjusted odds ratios (aOR) and 95% confidence intervals (95%CI) were estimated. RESULTS: Male volunteer firefighters were at increased odds for developing prostate (aOR = 1.26; 95%CI;[1.10- 1.44]) and male genital cancers combined (1.22;[1.07-1.39]), while reduced odds for endocrine cancer (0.41;[0.17-1.00]), and all leukemias (0.55;[0.35-0.86]), including lymphocytic (0.48;[0.24-0.97]); and chronic lymphocytic (0.40;[0.17-0.97]) leukemias. Female volunteer firefighters were at increased odds of developing of kidney cancer (2.51;[1.29-4.91]). CONCLUSIONS: Male volunteer firefighters are at increased odds for prostate and overall male genital cancers, while female volunteers are increased odds of kidney cancer.

Methodological and Practical Challenges in Synthesizing Occupational Cancer Studies.

Studies examining occupational exposures and cancer risk frequently report mixed findings; it is thus imperative for researchers to synthesize study results and identify any potential sources that explain such variabilities in study findings. However, when synthesizing study results using meta-analytic techniques, researchers often encounter a number of practical and methodological challenges. These challenges include (1) an incomparability of effect size measures due to large variations in research methodology; (2) a violation of the independence assumption for meta-analysis; (3) a violation of the normality assumption of effect size measures; and (4) a variation in cancer definitions across studies and changes in coding standards over time. In this paper, we first demonstrate these challenges by providing examples from a real dataset collected for a large meta-analysis project that synthesizes cancer mortality and incidence rates among firefighters. We summarize how each of these challenges has been handled in our meta-analysis. We conclude this paper by providing practical guidelines for handling challenges when synthesizing study findings from occupational cancer literature.

Clinician-Level Knowledge and Barriers to Hepatocellular Carcinoma Surveillance.

Importance: Surveillance for hepatocellular carcinoma (HCC) in patients with cirrhosis is underused. Identifying potentially modifiable factors to address barriers in HCC surveillance is critical to improve patient outcomes. Objective: To evaluate clinician-level factors contributing to underuse of HCC surveillance in patients with cirrhosis. Design, Setting, and Participants: This survey study included primary care clinicians (PCCs) and gastroenterology and hepatology clinicians at 5 safety-net health systems in the US. Clinicians were surveyed from March 15 to September 15, 2023, to assess knowledge, attitudes, beliefs, perceived barriers, and COVID-19-related disruptions in HCC surveillance in patients with cirrhosis. Data were analyzed from October to November 2023. Main Outcome and Measures: HCC surveillance knowledge was assessed with 6 questions querying the respondent's ability to correctly identify appropriate use of HCC surveillance. Attitudes, perceived barriers, and beliefs regarding HCC surveillance and perceived impact of the COVID-19 pandemic-related disruptions with HCC surveillance were assessed with a series of statements using a 4-point Likert scale and compared PCCs and gastroenterology and hepatology clinicians. Results: Overall, 347 of 1362 clinicians responded to the survey (25.5% response rate), among whom 142 of 237 (59.9%) were PCCs, 48 of 237 (20.3%) gastroenterology and hepatology, 190 of 236 (80.5%) were doctors of medicine and doctors of osteopathic medicine, and 46 of 236 (19.5%) were advanced practice clinicians. On HCC knowledge assessment, 144 of 270 (53.3%) scored 5 or more of 6 questions correctly, 37 of 48 (77.1%) among gastroenterology and hepatology vs 65 of 142 (45.8%) among PCCs (P < .001). Those with higher HCC knowledge scores were less likely to report barriers to HCC surveillance. PCCs were more likely to report inadequate time to discuss HCC surveillance (37 of 139 [26.6%] vs 2 of 48 [4.2%]; P = .001), difficulty identifying patients with cirrhosis (82 of 141 [58.2%] vs 5 of 48 [10.4%]; P < .001), and were not up-to-date with HCC surveillance guidelines (87 of 139 [62.6%] vs 5 of 48 [10.4%]; P < .001) compared with gastroenterology and hepatology clinicians. While most acknowledged delays during the COVID-19 pandemic, 62 of 136 PCCs (45.6%) and 27 of 45 gastroenterology and hepatology clinicians (60.0%) reported that patients with cirrhosis could currently complete HCC surveillance without delays. Conclusions and Relevance: In this survey study, important gaps in knowledge and perceived barriers to HCC surveillance were identified. Effective delivery of HCC education to PCCs and health system-level interventions must be pursued in parallel to address the complex barriers affecting suboptimal HCC surveillance in patients with cirrhosis.

Endometrial Cancer Survival in Populations of African Descent.

To examine whether the endometrial cancer (EC) survival disadvantage among Black populations is US-specific, a comparison between African descent populations from different countries with a high development index is warranted. We analyzed 28,213 EC cases from cancer registries in Florida (2005-2018) and Martinique (2005-2018)/Guadeloupe (2008-2018), French Caribbean islands. Kaplan-Meier and all-cause Cox proportional hazards models were used to compare survival. Models were stratified by EC histology type and the main predictor examined was race/ethnicity [non-Hispanic White (NHW) and Black (NHB) women in the US versus Black women residing in the Caribbean]. For endometrioid and non-endometrioid EC, after adjusting for age, histology, stage at diagnosis, receipt of surgery, period of diagnosis, and poverty level, US NHB women and Caribbean Blacks had a higher risk of death relative to US NHWs. There was no difference between US NHBs and Caribbean Blacks (HR 1.07, 95% CI: 0.88-1.30) with endometrioid EC. However, Caribbean Black women with non-endometrioid carcinomas had a 40% (HR 1.40, 95% CI: 1.13-1.74) higher risk of death than US NHBs. The low EC survival among US Black women extends to foreign populations of African descent. For the aggressive non-endometrioid ECs, survival in Caribbean Blacks outside of the US is considerably worse.

Avanzando Caminos (Leading Pathways): design and procedures of the Hispanic/Latino Cancer Survivorship Study.

Avanzando Caminos (Leading Pathways): The Hispanic/Latino Cancer Survivorship Cohort Study aims to examine the influence of sociocultural, medical, stress-related, psychosocial, lifestyle, behavioral, and biological factors on symptom burden, health-related quality of life, and clinical outcomes among Hispanics/Latinos who have been previously treated for cancer. Avanzando Caminos is a prospective, cohort-based study of 3000 Hispanics/Latinos who completed primary cancer treatment within the past 5 years that is representative of the general Hispanic/Latino population in the United States. Participants will complete self-report measures at baseline (time [T] 1), 6 months (T2), 1 year (T3), 2 years (T4), 3 years (T5), 4 years (T6), and 5 years (T7). Blood samples drawn for assessment of leukocyte gene expression, cardiometabolic markers, and genetic admixture will be collected at baseline (T1), 1 year (T3), 3 years (T5), and 5 years (T7). Medical and cancer characteristics and clinical outcomes will be extracted from the electronic medical record and/or state cancer registry at each time point. Data analysis will include general latent variable modeling and latent growth modeling. Avanzando Caminos will fill critical gaps in knowledge in order to guide future secondary and tertiary prevention efforts to mitigate cancer disparities and optimize health-related quality of life among Hispanic/Latino cancer survivors.

Disparities in incidence and survival for patients with Ewing sarcoma in Florida.

BACKGROUND: Ewing sarcoma (ES) is a malignant bone tumor most commonly affecting non-Hispanic White (NHW) adolescent males, though recognition among Hispanic individuals is rising. Prior population-based studies in the United States (US), utilizing Surveillance, Epidemiology, and End Results (SEER) have shown higher all-cause mortality among White Hispanics, Blacks, and those of low socioeconomic status (SES). Florida is not part of SEER but is home to unique Hispanic populations including Cubans, Puerto Ricans, South Americans that contrasts with the Mexican Hispanic majority in other US states. This study aimed to assess racial/ethnic disparities on incidence and survival outcomes among this diverse Florida patient population. METHODOLOGY: Our study examined all patients diagnosed with osseous ES (2005-2018) in Florida (n = 411) based on the state's population-based cancer registry dataset. Florida Age-adjusted Incidence Rates (AAIRs) were computed by sex and race-ethnicity and compared to the equivalent populations in SEER. Cause-specific survival disparities among Florida patients were examined using Kaplan-Meier analysis. Univariable and multivariable analyses using Cox regression were performed for race/ethnicity, with adjustment for age, sex, year of diagnosis, site of disease, staging, SES, and insurance type. RESULTS: There was a significantly higher incidence of osseous ES in Florida Hispanic males (AAIR 2.6/1,000,000); (95% CI: 2.0-3.2 per 1,000,000; n = 84) compared to the SEER Hispanic males (AAIR 1.2/1,000,000;1.1-1.4 per 1,000,000; n = 382). Older age, distant metastasis, lack of chemotherapy or surgical resection were statistically significant determinants of poor survival while SES, insurance status and race-ethnicity were not. However, among nonmetastatic ES, Florida Hispanics had an increased risk of death compared to Florida NHW (adjusted Hazard Ratio 2.32; 95%CI: 1.20-4.46; p = 0.012). CONCLUSIONS: Florida Hispanic males have a higher-than-expected incidence of osseous ES compared to the US. Hispanics of both sexes show remarkably worse survival for nonmetastatic disease compared to NHW. This disparity is likely multifactorial and requires further in-depth studies.

Distinct Prostate Cancer Survival Outcomes in Firefighters: A Population-Based Study.

Introduction: Survival outcomes for prostate cancer among specific occupational groups prone to regular medical check-ups vis-à-vis the general population have been understudied. For firefighters, a demographic subject to rigorous medical evaluations, possessing above-average medical expertise, and exposed to specific carcinogens of interest, prostate cancer survival in the US has never been studied. Methods: We conducted a retrospective study, utilizing data from the Florida Cancer Data System spanning 2004 to 2014, coupled with firefighter certification records from the Florida State Fire Marshal's Office. Our study cohort consisted of 1058 prostate cancer cases among firefighters as well as prostate cases for the Florida general population (n = 150,623). We compared cause-specific survival between the two using Cox regression models adjusted for demographics and clinical characteristics, including PSA levels, Gleason scores, and treatment modalities. Results: Firefighters demonstrated a higher five-year cause-specific survival rate (96.1%, 95% CI: 94.7-97.1%) than the general population (94.2%, 95%CI: 94.1-94.3%). Overall, firefighters' diagnoses were established at younger ages (median age 63 vs. 67 in the general population), exhibited a higher proportion of localized stage cancers (84.7% vs. 81.1%), and had a greater utilization of surgery (46.4% vs. 37.6%), a treatment modality with a high success rate but potential side effects. In multivariable analysis, firefighters displayed a survival advantage for localized stage (adjusted hazard ratio [aHR] = 0.53; 95%CI: 0.34-0.82). However, for regional or distant stages, firefighters aged 65 and above exhibited a higher risk of death (aHR = 1.84; 95% CI: 1.18-2.86) than the general population. Conclusion: Firefighters experience enhanced prostate cancer survival, primarily in cases diagnosed at localized stages, likely due to increased PSA testing. Nonetheless, for regional or distant stage, survival among older firefighters' lags behind that of the general population. Further investigations are warranted to unravel factors influencing the development of aggressive disease beyond PSA and Gleason scores in this population, as well as to assess the impact of a higher rate of surgical treatment on firefighters' quality of life.

ZIP Code to Genomic Code: Neighborhood Disadvantage, Aggressive Breast Cancer Biology, and Breast Cancer Outcomes.

OBJECTIVE: To determine the association between objective (geospatial) and subjective (perceived) measures of neighborhood disadvantage (ND) and aggressive breast cancer tumor biology, defined using validated social adversity-associated transcription factor (TF) activity and clinical outcomes. BACKGROUND: ND is associated with shorter breast cancer recurrence-free survival (RFS), independent of individual, tumor, and treatment characteristics, suggesting potential unaccounted biological mechanisms by which ND influences RFS. METHODS: We quantified TF-binding motif prevalence within promoters of differentially expressed genes for 147 tissue samples prospectively collected on the protocol. Covariate-adjusted multivariable regression analyzed objective and subjective ND scores with 5 validated TFs of social adversity and aggressive biology-pro-inflammatory activity [nuclear factor-κB ( NF-kB ), activator protein 1 ( AP-1 )], sympathetic nervous system (SNS) activity [cyclic 3'-5' adenosine monophosphate response element-binding protein ( CREB )], and protective cellular responses [interferon-regulatory factor ( IRF ) and signal transducer and activator of transcription ( STAT )]. To clinically validate these TFs as prognostic biomarkers of aggressive biology, logistic regression and multivariable Cox proportional-hazards models analyzed their association with Oncotype DX scores and RFS, respectively. RESULTS: Increasing objective ND was associated with aggressive tumor biology (up-regulated NF-kB , activator protein 1, down-regulated IRF , and signal transducer and activator of transcription) and SNS activation (up-regulated CREB ). Increasing subjective ND (eg, threat to safety) was associated with up-regulated NF-kB and CREB and down-regulated IRF . These TF patterns were associated with high-risk Oncotype DX scores and shorter RFS. CONCLUSIONS: In the largest human social genomics study, objective and subjective ND were significantly associated with TFs of aggressive biology and SNS activation. These TFs also correlated with worse clinical outcomes, implicating SNS activation as one potential mechanism behind ND survival disparities. These findings remain to be validated in a national cohort.

Assessing racial, ethnic, and nativity disparities in US cancer mortality using a new integrated platform.

BACKGROUND: Foreign-born populations in the United States have markedly increased, yet cancer trends remain unexplored. Survey-based Population-Adjusted Rate Calculator (SPARC) is a new tool for evaluating nativity differences in cancer mortality. METHODS: Using SPARC, we calculated 3-year (2016-2018) age-adjusted mortality rates and rate ratios for common cancers by sex, age group, race and ethnicity, and nativity. Trends by nativity were examined for the first time for 2006-2018. Traditional cancer statistics draw populations from decennial censuses. However, nativity-stratified populations are from the American Community Surveys, thus involve sampling errors. To rectify this, SPARC employed bias-corrected estimators. Death counts came from the National Vital Statistics System. RESULTS: Age-adjusted mortality rates were higher among US-born populations across nearly all cancer types, with the largest US-born, foreign-born difference observed in lung cancer among Black women (rate ratio = 3.67, 95% confidence interval [CI] = 3.37 to 4.00). The well-documented White-Black differences in breast cancer mortality existed mainly among US-born women. For all cancers combined, descending trends were more accelerated for US-born compared with foreign-born individuals in all race and ethnicity groups with changes ranging from -2.6% per year in US-born Black men to stable (statistically nonsignificant) among foreign-born Black women. Pancreas and liver cancers were exceptions with increasing, stable, or decreasing trends depending on nativity and race and ethnicity. Notably, foreign-born Black men and foreign-born Hispanic men did not show a favorable decline in colorectal cancer mortality. CONCLUSIONS: Although all groups show beneficial cancer mortality trends, those with higher rates in 2006 have experienced sharper declines. Persistent disparities between US-born and foreign-born individuals, especially among Black people, necessitate further investigation.

Trends and Disparities in Curative-Intent Treatment for Early-Stage Non-Small Cell Lung Cancer: A Population-Based Analysis of Surgery and SBRT.

BACKGROUND: Despite the increasing adoption of stereotactic body radiotherapy (SBRT) as a recommended alternative for early-stage non-small cell lung cancer (NSCLC), population-based research on racial/ethnic disparities in curative-intent treatment accounting for SBRT remains limited. This study investigated trends and disparities in receiving curative-intent surgery and/or SBRT in a diverse, retrospective cohort. METHODS: Early-stage NSCLC cases (2005-2017) from the Florida cancer registry were linked to individual-level statewide discharge data containing comorbidities and specific treatment information. Joinpoint regression assessed trends in treatment receipt. Multivariable logistic regression examined associations between race/ethnicity and treatment type. RESULTS: Among 64,999 patients with early-stage NSCLC, 71.6% received curative-intent treatment (surgery and/or SBRT): 73.1%, 72.4%, and 60.3% among Hispanic, White, and Black patients, respectively (P < 0.01). SBRT use increased steeply from 2005 to 2007 and then by 7.9% annually from 2007 to 2017 (P < 0.01); curative-intent surgery remained stable from 2005 to 2014 before declining by 6.2% annually during 2014-2017 (P = 0.04). The Black-White disparity in receipt of curative-intent treatment was significant [ORadj, 0.65; 95% confidence interval (CI), 0.60-0.71]. Patients with Charlson comorbidity index (CCI)≥3 had 36% (ORadj, 0.64; 95% CI, 0.60-0.69) lower odds of receiving curative-intent surgery and no significant difference for SBRT (ORadj, 1.06; 95% CI, 0.93-1.20) compared with CCI = 0. CONCLUSIONS: Racial disparities in receiving curative-intent treatment for early-stage NSCLC persist despite the availability of SBRT, suggesting the full potential of curative-intent treatment for early-stage NSCLC remains unachieved. IMPACT: Addressing disparities in early-stage NSCLC requires addressing differential treatment patterns and enhancing accessibility to treatments like underutilized SBRT, particularly for high-comorbidity populations such as Black patients.

Cancer mortality in Germany-born Americans and Germans.

INTRODUCTION: Comparing cancer mortality and associated risk factors among immigrant populations in a host country to those in their country of origin reveals disparities in cancer risk, access to care, diagnosis, and disease management. This study compares cancer mortality between the German resident population and Germany-born individuals who migrated to the US. METHODS: Cancer mortality data from 2008-2018 were derived for Germans from the World Health Organization database and for Germany-born Americans resident in four states (California, Florida, Massachusetts, and New York) from respective Departments of Vital Statistics. We calculated age-standardized mortality rates (ASMRs) using the European standard population and standardized mortality ratios (SMR) compared to the German resident population along with 95% confidence intervals (CIs). RESULTS: Germany-born American males had lower ASMRs (253.8 per 100,000) than German resident population (325.6 per 100,000). The difference in females was modest, with ASMRs of 200.7 and 203.7 per 100,000, respectively. For all cancers, Germany-born American males had an SMR of 0.72 (95% CI: 0.70-0.74) and females 0.98 (95% CI: 0.95-1.00). Male SMRs among Germany-born Americans were significantly below one for oral cavity, stomach, colorectal, liver, lung, prostate, and kidney cancer. Among females, SMRs were below one for oral cavity, stomach, colorectal, gallbladder, breast, cervix uteri, and kidney cancer. For both sexes, SMRs were over one for bladder cancer (1.14 for males, 1.21 for females). Mortality was higher for lung cancer (SMR: 1.68), non-Hodgkin's lymphoma (1.18) and uterine cancer (1.22) among Germany-born American females compared to the German resident population. CONCLUSION: Germany-born American males but not females showed lower cancer mortality than German resident population. Disparities may stem from variations in risk factors (e.g., smoking and alcohol use) as well as differences in screening practices and participation, cancer treatment, besides some residual potential "healthy immigrant effect".

Macroevolution of floral scent chemistry across radiations of male euglossine bee-pollinated plantsMacroevolución de olores florales a través de radiaciones de plantas polinizadas por abejas euglosinas machosMacroevolução dos voláteis florais em radiações de plantas polinizadas por machos de abelhas Euglossini.

Floral volatiles play key roles as signaling agents that mediate interactions between plants and animals. Despite their importance, few studies have investigated broad patterns of volatile variation across groups of plants that share pollinators, particularly in a phylogenetic context. The "perfume flowers," Neotropical plant species exhibiting exclusive pollination by male euglossine bees in search of chemical rewards, present an intriguing system to investigate these patterns due to the unique function of their chemical phenotypes as both signaling agents and rewards. We leverage recently developed phylogenies and knowledge of biosynthesis, along with decades of chemical ecology research, to characterize axes of variation in the chemistry of perfume flowers, as well as understand their evolution at finer taxonomic scales. We detect pervasive chemical convergence, with many species across families exhibiting similar volatile phenotypes. Scent profiles of most species are dominated by compounds of either the phenylpropanoid or terpenoid biosynthesis pathways, while terpenoid compounds drive more subtle axes of variation. We find recapitulation of these patterns within two independent radiations of perfume flower orchids, in which we further detect evidence for the rapid evolution of divergent floral chemistries, consistent with the putative importance of scent in the process of adaptation and speciation.

Incidence of Etiology-specific Hepatocellular Carcinoma: Diverging Trends and Significant Heterogeneity by Race and Ethnicity.

BACKGROUND & AIMS: The main causes of hepatocellular carcinoma (HCC) include chronic hepatitis C and B viral infections (HCV, HBV), nonalcoholic fatty liver disease (NAFLD), and alcohol-related disease (ALD). Etiology-specific HCC incidence rates and temporal trends on a population-basis are needed to improve HCC control and prevention. METHODS: All 14,420 HCC cases from the Florida statewide cancer registry were individually linked to data from the hospital discharge agency and the viral hepatitis department to determine the predominant etiology of each case diagnosed during 2010 to 2018. Age-adjusted incidence rates (AAIRs) were used to assess the intersection between etiology and detailed race-ethnicity. Etiology-specific temporal trends based on diagnosis year were assessed using Joinpoint regression. RESULTS: HCV remains the leading cause of HCC among men, but since 2017 NAFLD-HCC is the leading cause among women. HCV-HCC AAIRs are particularly high among U.S.-born minority men, including Puerto Rican (10.9 per 100,000), African American (8.0 per 100,000), and U.S.-born Mexican American men (7.6 per 100,000). NAFLD is more common among all Hispanics and Filipinos and HBV-HCC among Asian and Haitian black men. HCV-HCC surpasses HBV-HCC in Asian women. ALD-HCC is high among specific Hispanic male groups. Population-based HCV-HCC rates experienced a rapid decline since 2015 (-9.6% annually), whereas ALD-HCC (+6.0%) and NAFLD-HCC (+4.3%) are rising (P < .05). CONCLUSIONS: New direct acting anti-viral drugs have impacted rates of HCV-HCC, offsetting important increases in both ALD- and NAFLD-HCC. Hispanics may be a group of concern because of higher rates for ALD- and NAFLD-HCC. HCC etiology varies remarkably and may warrant specific interventions by detailed race-ethnicity.

Associations Between Neighborhood-Level Income and Triple-Negative Breast Cancer in a Majority-Minority Population.

BACKGROUND: Previous studies on disparities in triple-negative breast cancer (TNBC) focus on race/ethnicity, with few exploring the impact of contextual factors such as neighborhood-level income. This study evaluates the effect of neighborhood-level income on disparities in TNBC among a racially and ethnically diverse cohort, after accounting for granular individual-level risk factors of TNBC. PATIENTS AND METHODS: Patients with stage I-IV breast cancer from 2005 to 2017 were identified from our local tumor registry. The primary outcome was diagnosis of TNBC. Using 5-years estimates from the American Community Survey, we obtained median household income for each census tract which was categorized into quartiles. Mixed effects logistic regression was conducted and stratified by race and ethnicity, controlling for individual-level sociodemographic, comorbidities, and tumor characteristics. RESULTS: Among 5377 breast cancer registry patients, 16.5% were diagnosed with TNBC. The majority were Hispanic (50.1%) followed by non-Hispanic Black (NHB) (28.0%). After controlling for individual-level covariables including race and ethnicity, comorbidities, and tumor characteristics, women from low-income neighborhoods had increased odds of TNBC compared with other breast cancer subtypes, compared with those in high-income neighborhoods [odds ratio (OR) 1.33; 95% confidence interval (CI) 1.04, 1.70, p < 0.001]. In stratified analyses, NHB patients from low-income neighborhoods had two times the odds of TNBC diagnosis compared with those from high-income neighborhoods (OR 2.11; 95% CI 1.02, 4.37). CONCLUSION: We found that living in a low-income neighborhood is associated with an increased odds of TNBC independent of granular individual-level TNBC risk factors, particularly NHB race. More striking, NHB living in low-income neighborhoods had increased odds of TNBC compared with NHB living in high-income neighborhoods. Our results suggest potential unaccounted gene-environment and/or social (api)genomic interactions between neighborhood-level income and TNBC subtype development.

Increasing risk of hepatocellular carcinoma with successive generations in the United States among Mexican American adults: The Multiethnic Cohort.

BACKGROUND: US-born Latinos have a higher incidence of hepatocellular carcinoma (HCC) than foreign-born Latinos. Acculturation to unhealthy lifestyle behaviors and an immigrant self-selection effect may play a role. In this study, the authors examined the influence of generational status on HCC risk among Mexican American adults. METHODS: The analytic cohort included 31,377 self-reported Mexican Americans from the Multiethnic Cohort Study (MEC). Generational status was categorized as: first-generation (Mexico-born; n = 13,382), second-generation (US-born with one or two parents born in Mexico; n = 13,081), or third-generation (US-born with both parents born in the United States; n = 4914). Multivariable Cox proportional hazards regression was performed to examine the association between generational status and HCC incidence. RESULTS: In total, 213 incident HCC cases were identified during an average follow-up of 19.5 years. After adjusting for lifestyle and neighborhood-level risk factors, second-generation and third-generation Mexican Americans had a 37% (hazard ratio [HR], 1.37; 95% confidence interval [CI], 0.98-1.92) and 66% (HR, 1.66; 95% CI, 1.11-2.49) increased risk of HCC, respectively, compared with first-generation Mexican Americans (p for trend = 0.012). The increased risk associated with generational status was mainly observed in males (second-generation vs. first-generation: HR, 1.60 [95% CI, 1.05-2.44]; third-generation vs. first-generation: HR, 2.08 [95% CI, 1.29-3.37]). CONCLUSIONS: Increasing generational status of Mexican Americans is associated with a higher risk of HCC. Further studies are needed to identify factors that contribute to this increased risk.

Migração e mortalidade por câncer entre os migrantes colombianos nos EUA: um estudo com dados de declaração de óbito / Migration and cancer mortality among Colombian migrants in the USA: a death certification study

Resumo Este estudo teve como objetivo comparar padrões de mortalidade por câncer entre os imigrantes colombianos nos EUA e colombianos em sua terra natal. Dados de 2008 a 2012 foram coletados, e foram calculadas taxas de mortalidade por câncer de colombianos residindo em seu país natal e colombianos residindo em Califórnia, Flórida e Nova York, bem como taxas específicas de mortalidade por idade e sexo por cada 100.000 pessoas. Para comparar as duas populações, tanto antes como após a correção pela escolaridade, as razões de taxas de mortalidade (MRR) foram estimadas por modelo de regressão binomial negativa. Foi descoberto que colombianos em sua terra natal apresentam taxas de mortalidade por câncer mais altas quando comparados aos que residem nos EUA (MRR masculino 1,4 (IC 95%: 1,2-1,5), MRR feminino 1,5 (IC 95%: 1,3-1,7)). Essas diferenças persistem para a maioria dos tipos de câncer, mesmo após correção pela escolaridade. Os colombianos em sua terra natal apresentaram taxa de mortalidade por câncer gástrico (MRR masculino 2,6; feminino 2,8) e cervical (MRR 5,0) significativamente mais alta em comparação com os que residem nos EUA. As desigualdades educacionais na mortalidade por câncer foram mais acentuadas para aqueles que moram em sua terra natal. A menor taxa de mortalidade por câncer observada entre os colombianos nos EUA, porém, não pode ser atribuída às diferenças de escolaridade, um indicador de status socioeconômico. Em vez disso, provavelmente ocorre devido à maior acessibilidade aos serviços de saúde preventivos e curativos nos EUA.

Abstract We aim to compare cancer mortality rates of USA Colombian migrants (USA Colombians) to Colombians in their country of origin (CO Colombians). Using Colombian national mortality data and data on cancer deaths among Colombians residing in the states of California, Florida, and New York (USA Colombians) for the period 2008-2012, we estimated sex-specific and age-standardized mortality rates (ASMR), expressed per 100,000 persons. For comparisons between the two populations before and after adjustment for educational level, negative binomial regression models were used to compute Mortality Rate Ratios (MRR). CO Colombians had higher cancer mortality rates compared with USA Colombians (male MRR 1.4 [95%CI: 1.2-1.5], female MRR 1.5 [95%CI: 1.3-1.7]). These differences persisted for most cancers even after adjustment for education. CO Colombians had significantly higher mortality from gastric (MRR 2.6 in males and 2.8 in females) and cervical cancer (MRR 5.0) compared with US Colombians. Educational inequalities in cancer mortality were more pronounced among CO Colombians than among USA Colombians. Lower cancer mortality observed among USA Colombians cannot be attributed to differences in education, an indicator of socio-economic status. Rather, it is likely due to better access to preventive and curative healthcare in the USA.

Male Emphorini (Hymenoptera: Apidae) bees use flowers of Ipomoea carnea (Convolvulaceae) as overnight resting sites / Machos de abelhas Emphorini (Hymenoptera: Apidae) utilizam flores de Ipomoea carnea (Convolvulaceae) como locais de pernoite

Abstract The present study describes the behavior of male Emphorini bees in exploiting Convolvulaceae flowers as sleeping-sheltering place. The observations occurred inadvertently during a field study in an Agroforestry System in the Caatinga region, near the banks of the São Francisco River in Petrolina, Pernambuco - NE-Brazil. Males were observed and collected in wilted flowers of Ipomoea carnea (Convolvulaceae) during the evening. The sampling revealed nine Emphorini bees, belonging to three oligolectic species specialized on Convolvulaceae. We propose that the infundibuliform morphology of Ipomoea carnea flowers and the varied timing of anthesis could influence the choice of these flowers as overnight resting places. Furthermore, we endorse the idea present in the literature that males of oligolectic bees generally engage in patrolling flowers utilized by females, thereby enhancing the chances of encountering potential mates, making these flowers rendezvous places. The observation of this behavior highlights the interdependence between bees and plants and raises the possibility that the loss of these flowers could negatively impact bees not only in a nutrition aspect but also regarding shelter and reproduction.

Resumo O presente estudo documenta o comportamento de abelhas machos do grupo Emphorini em explorar flores da família Convolvulaceae como local para dormir e se abrigar. As observações foram realizadas inadvertidamente durante um estudo de campo em um Sistema Agroflorestal na região da Caatinga, próximo às margens do Rio São Francisco, em Petrolina, Pernambuco - Nordeste do Brasil. Machos foram observados e coletados em flores fechadas de Ipomoea carnea (Convolvulaceae) durante o entardecer. Em nossa amostragem, encontramos nove machos da tribo Emphorini, pertencentes a três espécies oligoléticas especializadas em Convolvulaceae. Propomos que a morfologia infundibuliforme das flores de Ipomoea carnea e os diferentes períodos de antese das flores podem influenciar a escolha dessas flores como locais de descanso durante à noite. Além disso, nossos dados endossam a ideia de que machos de abelhas oligoléticas geralmente patrulham flores utilizadas por fêmeas, aumentando assim as chances de encontrar possíveis parceiras, tornando essas flores locais de encontro para acasalamento. O registro desse comportamento destaca a interdependência entre abelhas e plantas e levanta a possibilidade de que a perda dessas flores possa impactar negativamente as abelhas não apenas em relação a sua nutrição, mas também em relação ao abrigo e reprodução.

Demographic and socioeconomic determinants of access to care: A subgroup disparity analysis using new equity-focused measurements.

Disparities in healthcare access and utilization associated with demographic and socioeconomic status hinder advancement of health equity. Thus, we designed a novel equity-focused approach to quantify variations of healthcare access/utilization from the expectation in national target populations. We additionally applied survey-weighted logistic regression models, to identify factors associated with usage of a particular type of health care. To facilitate generation of analysis datasets, we built an National Health and Nutrition Examination Survey (NHANES) knowledge graph to help automate source-level dynamic analyses across different survey years and subjects' characteristics. We performed a cross-sectional subgroup disparity analysis of 2013-2018 NHANES on U.S. adults for receipt of diabetes treatments and vaccines against Hepatitis A (HAV), Hepatitis B (HBV), and Human Papilloma (HPV). Results show that in populations with hemoglobin A1c level ≥6%, patients with non-private insurance were less likely to receive newer and more beneficial antidiabetic medications; being Asian further exacerbated these disparities. For widely used drugs such as insulin, Asians experienced insignificant disparities in odds of prescription compared to White patients but received highly inadequate treatments with regard to their distribution in U.S. diabetic population. Vaccination rates were associated with some demographic/socioeconomic factors but not the others at different degrees for different diseases. For instance, while equity scores increase with rising education levels for HBV, they decrease with rising wealth levels for HPV. Among women vaccinated against HPV, minorities and poor communities usually received Cervarix while non-Hispanic White and higher-income groups received the more comprehensive Gardasil vaccine. Our study identified and quantified the impact of determinants of healthcare utilization for antidiabetic medications and vaccinations. Our new methods for semantics-aware disparity analysis of NHANES data could be readily generalized to other public health goals to support more rapid identification of disparities and development of policies, thus advancing health equity.
