RESUMO

African-ancestry (AA) participants are underrepresented in genetics research. Here, we conducted a transcriptome-wide association study (TWAS) in AA female participants to identify putative breast cancer susceptibility genes. We built genetic models to predict levels of gene expression, exon junction, and 3' UTR alternative polyadenylation using genomic and transcriptomic data generated in normal breast tissues from 150 AA participants and then used these models to perform association analyses using genomic data from 18,034 cases and 22,104 controls. At Bonferroni-corrected P < 0.05, we identified six genes associated with breast cancer risk, including four genes not previously reported (CTD-3080P12.3, EN1, LINC01956 and NUP210L). Most of these genes showed a stronger association with risk of estrogen-receptor (ER) negative or triple-negative than ER-positive breast cancer. We also replicated the associations with 29 genes reported in previous TWAS at P < 0.05 (one-sided), providing further support for an association of these genes with breast cancer risk. Our study sheds new light on the genetic basis of breast cancer and highlights the value of conducting research in AA populations.

RESUMO

Human subjects research and drug and device development currently base their findings largely on the genetic data of the non-Hispanic White population, excluding People of Color. This practice puts People of Color at a distinct and potentially deadly disadvantage in being treated for sickness, disability, and disease, as seen during the COVID-19 pandemic. Major disparities exist in all chronic health conditions, including cancer. Data show that less than 2% of genetic information being studied today originates from people of African ancestry. If genomic datasets do not adequately represent People of Color, new drugs and genetic therapies may not work as well as for people of European descent. Addressing the urgent concern that historically marginalized people may again be excluded from the next technological leap affecting human health and the benefits it will bring will requires a paradigm shift. Thus, on behalf of underserved and marginalized people, we developed the Together for CHANGE (T4C) initiative as a unique collaborative public-private partnership to address the concern. The comprehensive programs designed in the T4C initiative, governed by the Diaspora Human Genomics Institute founded by Meharry Medical College, will transform the landscape of education and health care and positively affect global Black communities for decades to come.

RESUMO

BACKGROUND: Improving equity and early access to palliative care for underserved populations in Canada is a priority. Little is known regarding access to palliative and end-of-life care in the Black population. METHODS: We undertook a scoping review using the framework by Arksey and O'Malley to identify knowledge, access gaps, and experiences of palliative and end-of-life care among Blacks living with life-limiting illnesses in Canada. Primary studies, discussion papers, books, and reports were considered eligible. We followed a comprehensive search strategy developed by an information scientist. Searches were performed in the following bibliographic databases: Medline, EMBASE, PsycINFO via OVID, CINAHL via EBSCOhost, Scopus and Cochrane Library via Wiley. The search strategy was derived from three main concepts: (1) Black people; (2) Canada and Canadian provinces; (3) Palliative, hospice, or end-of-life care. No publication date or language limits were applied. Titles and abstracts were screened for eligibility by one reviewer and full text by two independent reviewers. RESULTS: The search yielded 233 articles. Nineteen articles were selected for full-text review, and 7 articles met the inclusion criteria. These studies were published between 2010 and 2021, and conducted in the provinces of Ontario and Nova Scotia only. Studies used both quantitative and qualitative methods and included cancer decedents, next of kin, family caregivers and religious leaders. Sample sizes in various studies ranged from 6 - 2,606 participants. Included studies reported a general lack of understanding about palliative and end-of-life care, positive and negative experiences, and limited access to palliative and end-of-life care for Blacks, across all care settings. CONCLUSION: Findings suggest limited knowledge of palliative care and inequities in access to palliative and end-of-life care for Blacks living with life-limiting illnesses in 2 Canadian provinces. There is an urgent need for research to inform tailored and culturally acceptable strategies to improve understanding and access to palliative care and end-of-life care among Blacks in Canada.

RESUMO

Human papillomavirus (HPV) proteins may elicit antibody responses in the process toward HPV-related malignancy. However, HPV seroepidemiology in noncervical HPV-related cancers remains poorly understood, particularly in populations with a high prevalence of human immunodeficiency virus (HIV). Using a glutathione S-transferase-based multiplex serology assay, antibodies against E6, E7 and L1 proteins of HPV16 and HPV18 were measured in sera of 535 cases of noncervical HPV-related cancers (anal (n = 104), vulval (n = 211), vaginal (n = 49), penile (n = 37) and oropharyngeal (n = 134)) and 6651 non-infection-related cancer controls, from the Johannesburg Cancer Study that recruited Black South African with newly diagnosed cancer between 1995 and 2016. Logistic and Poisson regression models were used to calculate adjusted odds ratios (aOR) and prevalence ratios (aPR) and 95% confidence intervals (CI) in cases versus controls. HPV16 E6 was more strongly associated with noncervical HPV-related cancers than HPV16 L1 or E7, or HPV18 proteins: anal (females (HPV16 E6 aOR = 11.50;95%CI:6.0-22.2), males (aOR = 10.12;95%CI:4.9-20.8), vulval (aOR = 11.69;95%CI:7.9-17.2), vaginal (aOR = 10.26;95%CI:5.0-21), penile (aOR = 18.95;95%CI:8.9-40), and oropharyngeal (females (aOR = 8.95;95%CI:2.9-27.5), males (aOR = 3.49;95%CI:1.8-7.0)) cancers. HPV16-E6 seropositivity ranged from 24.0% to 35.1% in anal, vulval, vaginal and penile cancer but was significantly lower (11.2%) in oropharyngeal cancer. After adjustment for HIV, prevalence of which increased from 22.2% in 1995-2005 to 54.1% in 2010-2016, HPV16 E6 seropositivity increased by period of diagnosis (aPR for 2010-2016 vs. 1995-2006 = 1.84;95%CI:1.1-3.0). Assuming HPV16 E6 seroprevalence reflects HPV attributable fraction, the proportion of certain noncervical-HPV-related cancers caused by HPV is increasing over time in South Africa. This is expected to be driven by the increasing influence of HIV.

RESUMO

BACKGROUND: Black-White racial disparities in cancer mortality are well-documented in the US. Given the estimated shortage of oncologists over the next decade, understanding how access to oncology care might influence cancer disparities is of considerable importance. We aim to examine the association between oncology provider density in a county and Black-White cancer mortality disparities. METHODS: An ecological study of 1048 US counties was performed. Oncology provider density was estimated using the 2013 National Plan and Provider Enumeration System data. Black:White cancer mortality ratio was calculated using 2014-2018 age-standardized cancer mortality rates from State Cancer Profiles. Linear regression with covariate adjustment was constructed to assess the association of provider density with (1) Black:White cancer mortality ratio, and (2) cancer mortality rates overall, and separately among Black and White persons. RESULTS: The mean Black:White cancer mortality ratio was 1.12, indicating that cancer mortality rate among Black persons was on average 12% higher than that among White persons. Oncology provider density was significantly associated with greater cancer mortality disparities: every 5 additional oncology providers per 100 000 in a county was associated with a .02 increase in the Black:White cancer mortality ratio (95% CI: .007 to .03); however, the unexpected finding may be explained by further analysis showing that the relationship between oncology provider density and cancer mortality was different by race group. Every 5 additional oncologists per 100 000 was associated with a 1.6 decrease per 100 000 in cancer mortality rates among White persons (95% CI: -3.0 to -.2), whereas oncology provider density was not associated with cancer mortality among Black persons. CONCLUSION: Greater oncology provider density was associated with significantly lower cancer mortality among White persons, but not among Black persons. Higher oncology provider density alone may not resolve cancer mortality disparities, thus attention to ensuring equitable care is critical.


Our study provides timely information to address the growing concern about the need to increase oncology supply and the impact it might have on racial disparities in cancer outcomes. This analysis of counties across the US is the first study to estimate the association of oncology provider density with Black-White racial disparities in cancer mortality. We show that having more oncology providers in a county is associated with significantly lower cancer mortality among the White population, but is not associated with cancer mortality among the Black population, thereby leading to a disparity. Our findings suggest that having more oncology providers alone may be insufficient to overcome existing disadvantages for Black patients to access and use high-quality cancer care. These findings have important implications for addressing racial disparities in cancer outcomes that are persistent and well-documented in the US.

RESUMO

BACKGROUND: Uterine fibroids are non-cancerous neoplasms that arise from the uterus affecting over 75% of women. However, there is a disparity with Black women having an increased prevalence of nearly 80%. Black women also experience increased symptom burden, including younger age at the time of diagnosis and increased number and volume of fibroids. Less is known about other ethnoracially diverse women such as Latinas and the potential cultural impacts on fibroid burden and treatment. METHODS: Community engagement studios were conducted to facilitate discussions with stakeholders on their uterine fibroid and menstruation experience. We recruited Black women (n = 6) diagnosed with uterine fibroids and Latinas (n = 7) without uterine fibroids. We held two virtual community engagement studios split by uterine fibroid diagnosis. The studios were not audio recorded and notes were taken by four notetakers. The notes were thematically analyzed in Atlas.ti using content analysis. RESULTS: Participants felt there was a lack of discussion around menstruation overall, whether in the home or school settings. This lack of menstruation education was pronounced when participants had their first menstruation experience, with many unaware of what to expect. This silence around menstruation led to a normalization of painful menstruation symptoms. When it came to different treatment options for uterine fibroids, some women wanted to explore alternative treatments but were dismissed by their healthcare providers. Many participants advocated for having discussions with their healthcare provider about life goals to discuss different treatment options for their uterine fibroids. CONCLUSION: Despite uterine fibroid diagnosis, there is silence around menstruation. Menstruation is a normal biological occurrence and needs to be discussed to help prevent delayed diagnosis of uterine fibroids and possibly other gynecological disorders. Along with increased discussions around menstruation, further discussion is needed between healthcare providers and uterine fibroid patients to explore appropriate treatment options.

RESUMO

Despite increasing numbers of regulatory approvals, deep learning-based computational pathology systems often overlook the impact of demographic factors on performance, potentially leading to biases. This concern is all the more important as computational pathology has leveraged large public datasets that underrepresent certain demographic groups. Using publicly available data from The Cancer Genome Atlas and the EBRAINS brain tumor atlas, as well as internal patient data, we show that whole-slide image classification models display marked performance disparities across different demographic groups when used to subtype breast and lung carcinomas and to predict IDH1 mutations in gliomas. For example, when using common modeling approaches, we observed performance gaps (in area under the receiver operating characteristic curve) between white and Black patients of 3.0% for breast cancer subtyping, 10.9% for lung cancer subtyping and 16.0% for IDH1 mutation prediction in gliomas. We found that richer feature representations obtained from self-supervised vision foundation models reduce performance variations between groups. These representations provide improvements upon weaker models even when those weaker models are combined with state-of-the-art bias mitigation strategies and modeling choices. Nevertheless, self-supervised vision foundation models do not fully eliminate these discrepancies, highlighting the continuing need for bias mitigation efforts in computational pathology. Finally, we demonstrate that our results extend to other demographic factors beyond patient race. Given these findings, we encourage regulatory and policy agencies to integrate demographic-stratified evaluation into their assessment guidelines.

RESUMO

Purpose: Conjunctival squamous cell carcinoma (conjSCC) is more prevalent and aggressive in sub-Saharan African countries compared with the rest of the world. This study aims to compare the genomic, immunophenotypic, and histologic features between patients from the United States and Ethiopia, to identify etiopathogenic mechanisms and unveil potential treatment strategies. Methods: We compared histologic features and mutational profiles using whole exome sequencing, high-risk human papillomavirus (HPV) status, PD-L1 expression, and tumor-infiltrating lymphocytes in conjSCC tumors of patients from Ethiopia (ETH; n = 25) and the United States (from MD Anderson [the MDA cohort]; n = 29). Genomic alterations were compared with SCCs from other anatomic sites using data from The Cancer Genome Atlas. Results: Solar elastosis was seen in 78% of ETH and 10% of MDA samples. Thicker tumors had higher density of CD8+ and CD3+ cells. HPV status was similar between the cohorts (ETH = 21% and MDA = 28%). The mean tumor mutation burden (TMB) was significantly higher in conjSCC (3.01/Mb, log10) and cutaneous SCC compared other SCC subtypes. ETH samples had higher TMB compared to the MDA cohort (3.34 vs. 2.73). Mutations in genes associated with ultraviolet light (UV) signature were most frequently encountered (SBS7b = 74% and SBS7a = 72%), with higher prevalence in the ETH cohort, whereas SBS2 and SBS13 signatures were more common among MDA HPV+ conjSCCs. Conclusions: Our findings suggest that UV exposure may play a major role in conjSCC, with a higher prevalence in the ETH cohort compared with the MDA cohort, where HPV also contributes.

RESUMO

OBJECTIVES: Eradication of Helicobacter pylori reduces the risk of gastric cancer (GC). Individuals with type 2 diabetes mellitus (T2DM) are known to be at increased risk for GC. In a cohort of H. pylori-positive individuals, we assessed whether those with T2DM were at risk of persistent infection following H. pylori treatment compared with individuals without T2DM. METHODS: A random subset of all individuals diagnosed as having H. pylori without intestinal metaplasia at endoscopy from 2015 to 2019 were stratified evenly by race (Black and White). After excluding those with T1DM and those without eradication testing after H. pylori treatment, logistic regression analysis was used to determine the association of T2DM with the risk of persistent H. pylori infection following treatment. RESULTS: In 138 patients, H. pylori eradication rates did not differ between the 27% of individuals with T2DM compared to those without (81.1% vs 81.2%). After adjusting for age, race, and insurance status, we found no significant increased risk of persistent H. pylori infection for individuals with T2DM (odds ratio 1.40; 95% confidence interval 0.49-3.99). CONCLUSIONS: H. pylori eradication rates do not differ by T2DM status, providing support for clinical trials of H. pylori eradication to reduce GC incidence among high-risk populations in the United States, such as individuals with T2DM.

RESUMO

BACKGROUND: Despite numerous studies on racial/ethnic disparities among patients with breast cancer, there is a paucity of literature evaluating racial/ethnic differences in 21-gene recurrence score (RS) and survival differences stratified by RS risk categories. We thus performed an observational cohort study to examine racial/ethnic disparities in the context of RS. METHODS: The National Cancer Database (NCDB) was queried for female patients diagnosed between 2006 and 2018 with estrogen receptor (ER)-positive, pT1-3N0-1aM0 breast cancer who received surgery followed by adjuvant endocrine therapy and had RS data available. Logistic multivariable analysis (MVA) was built to evaluate variables associated with RS ≥ 26. Cox MVA was used to evaluate OS. Subgroup analyses were performed to compare the magnitude of racial/ethnic differences stratified by RS. P values less than 0.017 were considered statistically significant based on Bonferroni correction. RESULTS: A total of 140,133 women were included for analysis. Of these, 115,651 (82.5%), 8,213 (5.9%), 10,814 (7.7%), and 5,455 (3.9%) were NHW, Hispanic, Black, and API women, respectively. Median (IQR) follow up was 66.2 months (48.0-89.8). Logistic MVA showed that, compared with NHW women, Black women were associated with higher RS (≥ 26 vs < 26: adjusted odds ratio [aOR] 1.19, 95% confidence interval [CI] 1.12-1.26, p < 0.001), while HW (aOR 0.93, 95% CI 0.86-1.00, p = 0.04) and API women (aOR 1.03, 95% CI 0.95-1.13, p = 0.45) were not. Cox MVA showed that, compared with NHW women, Black women had worse OS (adjusted hazards ratio [aHR] 1.10, 95% CI 1.02-1.19, p = 0.012), while HW (aHR 0.85, 95% CI 0.77-0.94, p = 0.001) and API (aHR 0.66, 95% CI 0.56-0.77, p < 0.001) women had better OS. In subgroup analysis, similar findings were noted among those with RS < 26, while only API women were associated with improved OS among others with RS ≥ 26. CONCLUSION: To our knowledge, this is the largest study using nationwide oncology database to suggest that Black women were associated with higher RS, while HW and API women were not. It also suggested that Black women were associated with worse OS among those with RS < 26, while API women were associated with improved OS regardless of RS when compared to NHW women.

RESUMO

BACKGROUND: Perforation of peptic ulcer (PPU) is the most morbid complication of peptic ulcer disease (PUD) with scant recent reports from sub-Saharan Africa. The aim of this study was to describe a PPU series from a single centre in South Africa and contrast the findings with other recent reports from sub-Saharan Africa. METHODS: A retrospective study of PPU at Kalafong Hospital in Pretoria was performed. The relationship of patient demographics, risk factors, ulcer pathology and severity scores to mortality were analysed. Recent similar reports from sub-Saharan Africa were reviewed and the findings compared to the current study and findings from high income countries (HIC). RESULTS: The study comprised 121 patients. The majority were black men with an average age of 46.6 years, with few comorbidities. A large proportion of patients admitted to risk factors and most presented to hospital 48 hours after the onset of symptoms. The majority (71%) of the perforations occurred in the stomach. The patient sex, age, risk factors and the mortality at 4% were similar to other African studies, although perforations were mainly duodenal in most of the African studies. The median age of patients in the East African studies was lower by 13 years. Patients in HIC series of PPU were older, more likely to be female, have duodenal perforations and a higher mortality than in the African series. CONCLUSION: Patients were mostly smokers, presented late to hospital and had gastric perforations. The findings of low mortality and male predominance concurred with those of other sub-Saharan African reports and were the opposite of trends in HIC.

RESUMO

Differences in tumor biology and genetic predisposition have been suggested as factors influencing overall survival and increased mortality in Black breast and ovarian cancer patients. Therefore, it is key to evaluate genetic susceptibilities in Afro-Caribbean patients because the black population in the US is not homogeneous. Identifying a high incidence of hereditary breast and ovarian cancer (HBOC) in Afro-Caribbean countries can lead to understanding the pattern of inherited traits in US-Caribbean immigrants and their subsequent generations. The paucity of projects studying the genetic landscape in these populations makes it difficult to design studies aimed at optimizing screening and prophylaxis strategies, which in turn, improve survival and mortality rates. This scoping review identifies and categorizes current research on the genetic paradigm of HBOC in the Afro-Caribbean population. We performed an evaluation of the evidence and generated a summary of findings according to preferred reporting items for systematic review and meta-analysis (PRISMA) Extension for Scoping Reviews guidelines. We included articles that assessed the incidence and prevalence of pathologic germline mutations and experience/barriers for genetic testing in Afro-Caribbean Countries and US-Caribbean patients. Our results highlight countries where genetic landscapes remain severely understudied and support recommending multigene testing in Caribbean-born patients. They highlight a need for further research on the genetic paradigm of HBOC in the Afro-Caribbean population to improve genetic testing/counseling and the subsequent adoption of early detection and risk reduction strategies.

RESUMO

IMPORTANCE: Epidemiologic evidence regarding the outcomes of dietary sodium intake on mortality remains limited for low-income individuals, particularly Black people. OBJECTIVE: To investigate the associations of excessive dietary sodium with all-cause and cause-specific mortality among predominantly low-income Black and White Americans. DESIGN, SETTING, AND PARTICIPANTS: This cohort study included participants aged 40 to 79 years from the Southern Community Cohort Study who were recruited at Community Health Centers in 12 southeastern states from 2002 to 2009. Analyses were conducted between March 2022 and June 2023. EXPOSURES: Dietary sodium intake was assessed using a validated food frequency questionnaire at baseline. MAIN OUTCOMES AND MEASURES: Multivariable-adjusted Cox regression was used to estimate hazard ratios (HRs) and 95% CIs for mortality outcomes (all-cause, cardiovascular disease [CVD], coronary heart disease [CHD], stroke, heart failure, cancer, and other) associated with sodium intake. Nonlinear associations and population-attributable risk (PAR) of the mortality burden associated with excess sodium were further assessed. RESULTS: Among the 64 329 participants, 46 185 (71.8%) were Black, 18 144 (28.2%) were White, and 39 155 (60.9%) were female. The mean (SD) age at study enrollment was 51.3 (8.6) years for Black participants and 53.3 (9.3) years for White counterparts. Mean (SD) dietary sodium intake was 4512 (2632) mg/d in Black individuals and 4041 (2227) mg/d in White individuals; 37 482 Black individuals (81.2%) and 14 431 White individuals (79.5%) exceeded the current dietary recommendations of 2300 mg/d. During a median (IQR) follow-up of 13.8 (11.3-15.8) years, 17 811 deaths were documented, including 5701 from CVD. After adjustment for potential confounders, in Black individuals, HRs per 1000-mg increase in daily sodium intake were 1.07 (95% CI, 1.03-1.10) and 1.08 (95% CI, 1.02-1.14) for deaths from total CVD and CHD, respectively; while in White individuals, the corresponding HRs were 1.08 (95% CI, 1.02-1.14) and 1.13 (95% CI, 1.03-1.23). No significant associations were found for cancer mortality. PAR estimates suggest that sodium intake above the recommended threshold may account for 10% of total CVD, 13% of CHD, and 30% of heart failure deaths in this low-income southern population. CONCLUSIONS AND RELEVANCE: In this cohort study of 64 329 low-income Americans, nearly 80% of study participants consumed sodium exceeding the current recommended daily amount, which was associated with 10% to 30% of CVD mortality. Public health programs targeted to reduce sodium intake among this underserved population may be beneficial.

RESUMO

INTRODUCTION: Complex challenges amongst ageing cohorts of adolescents and adults living with perinatally acquired HIV (PaHIV) may impact on hospitalisation. We report hospitalisation rates and explored predictive factors for hospitalisation in adolescents and adults (10-35 years) living with PaHIV in England. METHOD: Retrospective observational cohort study over a three-year period 2016-2019. Data collected included cause and duration of hospitalisation, HIV viral load and CD4 lymphocyte count. The primary outcome was overnight hospitalisation. Patients exited at study end/ transfer of care (TOC)/ loss to follow up (LTFU) or death. Maternity/hospital admissions at other centres were excluded. Admission rates per 100 person-years (95% CI) were calculated by age group. Negative binomial regression with generalized estimating equations was performed. RESULTS: 255 patients contributed 689 person-years of follow up. 56% were female and 83% were of a Black, Black British, Caribbean or African ethnicity. At baseline, the median age was 19 years (IQR 16-22). 36 individuals experienced a total of 62 admissions which resulted in 558 overnight stays (median stay was 5 nights). One person died (lymphoma), six had TOC and one was LTFU by the end of the three-year study period. Crude incidence of admission for the whole cohort was 9.0 per 100 PY (6.9-11.6). The respective crude incidence rates were 1.5 PY (0.0-8.2) in those aged 10-14 years and 3.5 PY (1.5-7.0) in the 15-19-year-olds. In those aged 20-24 years it was 14.5 PY (10.1-20.2) and in those >25 years the crude incidence rate was 11.7 PY (6.9-18.5). Factors significantly associated with admission were a CD4 lymphocyte count <200 cells/uL, adjusted IRR 4.0 (1.8-8.8) and a history of a CDC-C diagnosis, adjusted IRR 2.9 (1.6-5.3). 89% admissions were HIV-related: 45% new/current CDC-C diagnoses, 76% due to infection. CONCLUSIONS: Hospitalisation rates were four-fold higher in adults (>20 years of age) compared to adolescents (10-19-year-olds). The continuing challenges experienced by PaHIV youth require enhanced multidisciplinary support throughout adulthood.

RESUMO

Background: Black men are more likely to be diagnosed with prostate cancer than white men and may present with prostate cancer at a much later stage during the cancer journey. This could be due to a lower awareness of the signs and symptoms of prostate cancer, an unwillingness to report symptoms or a lack of trust in the healthcare system or a combination of these.Aim: The aims of this study were to raise awareness of prostate cancer in black communities in South of England and to evaluate the engagement and raising awareness campaigns.Method: This project involved two phases. The first phase focused on raising awareness of prostate cancer in black men and their families. The awareness was delivered using public facing activities such as stands and talks with participants. Additionally, online awareness activities were undertaken with either black men alone or black men and their families. The second phase of the project involved an evaluation of the raising awareness campaigns through interviews. A total of 320 black men and their families were involved in the awareness sessions and of these, 12 black men were interviewed. The interview transcripts were analysed using thematic analysis.Results: Analysis of the data generated three main themes including: increased knowledge and mindset change regarding prostate cancer, empowered to take community and personal action, as well as strategies and tools to raise awareness of prostate cancer among black communities.Conclusion: The raising awareness campaigns had a positive effect in terms of increasing black men's awareness of the risk factors associated with prostate cancer. Moreover, the campaigns enabled them to make lifestyle adjustments that could help them to reduce their likelihood of developing prostate cancer. Additionally, the participant's knowledge had improved, and they were empowered and motivated to make a difference to their lives and that of their communities.

RESUMO

This ecological study examined time series, from 2002 to 20121, of age-adjusted coefficients of cervical cancer mortality, in Brazil, in women aged 20 years or more, by race. The information sources were Brazil's mortality information system (Sistema de Informação sobre Mortalidade - SIM) and the official bureau of statistics (Instituto Brasileiro de Geografia e Estatística - IBGE). Annual changes in age-adjusted mortality rates were calculated using the Prais-Winsten linear regression method. Black women die more and the rate is decreasing less. Racial inequality has increased over the years. In 2002, there were 0.08 more deaths per 100,000 women in the black population than among white women; in 2021, the number was one death. Health policymaking should consider racial differences in the implementation of strategies and goals.


O objetivo desse artigo é analisar séries temporais da mortalidade por câncer de colo do útero segundo raça/cor no Brasil de 2002 a 2021. Estudo ecológico de séries temporais com dados do Sistema de Informação sobre Mortalidade e informações populacionais do IBGE. Variações anuais das taxas de mortalidade ajustadas por idade de mulheres de 20 anos ou mais foram estimadas pelo modelo de regressão linear simples com correção de Prais-Winsten. Foram registrados 133.429 óbitos por câncer de colo de útero, destes, 51,2% foram de mulheres negras. As mulheres negras morrem mais e têm menor queda do coeficiente. Houve aumento da desigualdade racial ao longo dos anos. Em 2002, ocorriam 0,08 óbitos/100 mil mulheres a mais na população negra comparada com a população branca; em 2021 esse número é de aproximadamente 1 óbito. Para a elaboração de políticas de saúde da mulher devem ser consideradas as diferenças raciais na implementação de estratégias e metas.

RESUMO

Importance: Medical debt is increasingly common in the US. Little is known regarding its association with population health. Objective: To examine the associations of medical debt with health status, premature death, and mortality at the county level in the US. Design, Setting, and Participants: This cross-sectional study was conducted at the US county level using 2018 medical debt data from the Urban Institute Debt in America project linked with 2018 data on self-reported health status and premature death from the County Health Rankings & Roadmaps and with 2015 to 2019 mortality data from the National Center for Health Statistics. Data analysis was performed from August 2022 to May 2023. Exposure: Share of population with any medical debt in collections and median amount of medical debt. Main Outcomes and Measures: Health status was measured as (1) the mean number of physically and mentally unhealthy days in the past 30 days per 1000 people, (2) the mean number of premature deaths measured as years of life lost before age 75 years per 1000 people, and (3) age-adjusted all-cause and 18 cause-specific mortality rates (eg, malignant cancers, heart disease, and suicide) per 100 000 person-years. Multivariable linear models were fitted to estimate the associations between medical debt and health outcomes. Results: A total of 2943 counties were included in this analysis. The median percentage of the county population aged 65 years or older was 18.3% (IQR, 15.8%-20.9%). Across counties, a median 3.0% (IQR, 1.2%-11.9%) of the population were Black residents, 4.3% (IQR, 2.3%-9.7%) were Hispanic residents, and 84.5% (IQR, 65.7%-93.3%) were White residents. On average, 19.8% (range, 0%-53.6%) of the population had medical debt. After adjusting for county-level sociodemographic characteristics, a 1-percentage point increase in the population with medical debt was associated with 18.3 (95% CI, 16.3-20.2) more physically unhealthy days and 17.9 (95% CI, 16.1-19.8) more mentally unhealthy days per 1000 people during the past month, 1.12 (95% CI, 1.03-1.21) years of life lost per 1000 people, and an increase of 7.51 (95% CI, 6.99-8.04) per 100 000 person-years in age-adjusted all-cause mortality rate. Associations of medical debt and elevated mortality rates were consistent for all leading causes of death, including cancer (1.12 [95% CI, 1.02-1.22]), heart disease (1.39 [95% CI, 1.21-1.57]), and suicide (0.09 [95% CI, 0.06-0.11]) per 100 000 person-years. Similar patterns were observed for associations between the median amount of medical debt and the aforementioned health outcomes. Conclusions and Relevance: These findings suggest that medical debt is associated with worse health status, more premature deaths, and higher mortality rates at the county level in the US. Therefore, policies increasing access to affordable health care, such as expanding health insurance coverage, may improve population health.

RESUMO

Disparities in data underlying clinical genomic interpretation is an acknowledged problem, but there is a paucity of data demonstrating it. The All of Us Research Program is collecting data including whole-genome sequences, health records, and surveys for at least a million participants with diverse ancestry and access to healthcare, representing one of the largest biomedical research repositories of its kind. Here, we examine pathogenic and likely pathogenic variants that were identified in the All of Us cohort. The European ancestry subgroup showed the highest overall rate of pathogenic variation, with 2.26% of participants having a pathogenic variant. Other ancestry groups had lower rates of pathogenic variation, including 1.62% for the African ancestry group and 1.32% in the Latino/Admixed American ancestry group. Pathogenic variants were most frequently observed in genes related to Breast/Ovarian Cancer or Hypercholesterolemia. Variant frequencies in many genes were consistent with the data from the public gnomAD database, with some notable exceptions resolved using gnomAD subsets. Differences in pathogenic variant frequency observed between ancestral groups generally indicate biases of ascertainment of knowledge about those variants, but some deviations may be indicative of differences in disease prevalence. This work will allow targeted precision medicine efforts at revealed disparities.

RESUMO

Black communities bear a hugely disproportionate share of Canada's HIV epidemic. Black persons annually represent up to one quarter of new diagnoses, while in contrast, diagnoses have been falling among white Canadians for the past two decades. There has been a notable lack of urgency and serious debate about why the trend persists and what to do about it. For too long, public institutions have reproduced hegemonic white supremacy and profoundly mischaracterized Black life. Consequently, Black communities suffer policies and programs that buttress systemic anti-Black racism, socio-economically disenfranchise Black communities, and in the process marginalize knowledgeable, experienced, and creative Black stakeholders. The Interim Committee on HIV among Black Canadian Communities (ICHBCC) is a group of Black researchers, service providers, and community advocates who came together in early 2022 to interject urgency to the HIV crisis facing Black communities. Specifically, the ICHBCC advocates for self-determined community leadership of research, policies, and programs, backed by access to appropriate resources, to change the trajectory of HIV among Black Canadian communities. In this article, we introduce the wider community to the Black HIV Manifesto that we developed in 2022.


RéSUMé: Les communautés noires constituent une part très disproportionnée de l'épidémie de VIH du Canada. Les personnes noires représentent annuellement jusqu'au quart des nouveaux diagnostics, tandis que les diagnostics diminuent chez les Canadiennes et les Canadiens de race blanche depuis 20 ans. Il y a une absence notable d'urgence et de débat sérieux sur la raison de la persistance de ces tendances et sur ce qu'il faudrait y faire. Pendant trop longtemps, les institutions publiques ont reproduit l'hégémonie de la suprématie blanche et extrêmement mal caractérisé les vies noires. Par conséquent, les communautés noires souffrent de politiques et de programmes qui soutiennent le racisme anti-Noirs systémique, privent les communautés noires de leurs droits socioéconomiques et marginalisent ainsi les connaissances, l'expérience et la créativité des parties prenantes noires. Le comité intérimaire sur le VIH dans les communautés noires du Canada (ICHBCC) est un groupe de chercheurs et de chercheuses, de prestataires de services et de porte-parole communautaires de race noire qui se sont regroupés au début de 2022 pour mettre l'accent sur le caractère urgent de la crise du VIH dans les communautés noires. Plus précisément, l'ICHBCC plaide en faveur d'un leadership communautaire autodéterminé de la recherche, des politiques et des programmes, appuyé par un accès aux ressources nécessaires, pour changer la trajectoire du VIH dans les communautés noires du Canada. Dans cet article, nous présentons à l'ensemble de la communauté le « manifeste noir sur le VIH ¼ que nous avons élaboré en 2022.

RESUMO

PURPOSE: This study assessed the prevalence of specific major adverse financial events (AFEs)-bankruptcies, liens, and evictions-before a cancer diagnosis and their association with later-stage cancer at diagnosis. METHODS: Patients age 20-69 years diagnosed with cancer during 2014-2015 were identified from the Seattle, Louisiana, and Georgia SEER population-based cancer registries. Registry data were linked with LexisNexis consumer data to identify patients with a history of court-documented AFEs before cancer diagnosis. The association of AFEs and later-stage cancer diagnoses (stages III/IV) was assessed using separate sex-specific multivariable logistic regression. RESULTS: Among 101,649 patients with cancer linked to LexisNexis data, 36,791 (36.2%) had a major AFE reported before diagnosis. The mean and median timing of the AFE closest to diagnosis were 93 and 77 months, respectively. AFEs were most common among non-Hispanic Black, unmarried, and low-income patients. Individuals with previous AFEs were more likely to be diagnosed with later-stage cancer than individuals with no AFE (males-odds ratio [OR], 1.09 [95% CI, 1.03 to 1.14]; P < .001; females-OR, 1.18 [95% CI, 1.13 to 1.24]; P < .0001) after adjusting for age, race, marital status, income, registry, and cancer type. Associations between AFEs prediagnosis and later-stage disease did not vary by AFE timing. CONCLUSION: One third of newly diagnosed patients with cancer had a major AFE before their diagnosis. Patients with AFEs were more likely to have later-stage diagnosis, even accounting for traditional measures of socioeconomic status that influence the stage at diagnosis. The prevalence of prediagnosis AFEs underscores financial vulnerability of patients with cancer before their diagnosis, before any subsequent financial burden associated with cancer treatment.
