RESUMO

Introduction: Veterans are at high risk for lung cancer and are an important group for lung cancer screening. Previous research suggests that lung cancer screening may not be reaching healthier and/or non-White individuals, who stand to benefit most from lung cancer screening. We sought to test whether lung cancer screening is associated with poor health and/or race and ethnicity among veterans. Methods: This cross-sectional, population-based study included veterans eligible for lung cancer screening (aged 55-79 years, ≥30 pack-year smoking history, current smokers or quit within 15 years, no previous lung cancer) in the 2017-2020 Behavioral Risk Factor Surveillance System surveys. Exposures were (1) poor health, defined as fair/poor health status and difficulty walking or climbing stairs, aligning with eligibility criteria for a pivotal lung cancer screening trial, and (2) race/ethnicity. The outcome was a receipt of lung cancer screening. All variables were self-reported. Results: Of 3,376 lung cancer screening-eligible veterans representing an underlying population of 866,000 individuals, 20.3% (95% CI=17.3, 23.6) had poor health, and 13.7% (95% CI=10.6, 17.5) identified as non-White. Poor health was strongly associated with lung cancer screening (adjusted RR=1.64, 95% CI=1.06, 2.27); one third of veterans screened for lung cancer would not qualify for a pivotal lung cancer screening trial in terms of health. Marked racial disparities were observed among veterans: after adjustment, non-White veterans were 67% less likely to report lung cancer screening than White veterans (adjusted RR=0.33, 95% CI=0.11, 0.66). Conclusions: Lung cancer screening is correlated with poorer health and White race/ethnicity among veterans, which may undermine its population-level effectiveness. These results highlight the need to promote lung cancer screening, especially for healthier and/or non-White veterans, an important group of Americans for lung cancer screening.

RESUMO

Importance: Lung cancer screening (LCS) via low-dose chest computed tomography can prevent mortality through surgical resection of early-stage cancers, but it is unknown whether poor health is associated with screening. Though LCS may be associated with better outcomes for non-Hispanic Black individuals, it is unknown whether racial or ethnic disparities exist in LCS use. Objective: To determine whether health status is associated with LCS and whether racial or ethnic disparities are associated with LCS independently of health status. Design, Setting, and Participants: This cross-sectional, population-based study of community-dwelling US adults used data from Behavioral Risk Factor Surveillance System annual surveys, 2017 to 2020. Participants were aged 55 to 79 years, with a less than 30 pack-year smoking history, and were current smokers or those who quit within 15 years. Data were analyzed from August to November 2021. Exposures: Self-reported health status and race and ethnicity. Main Outcomes and Measures: Self-reported LCS in the last 12 months. Results: Of 14 550 individuals (7802 men [55.5%]; 7527 [55.0%] aged 65-79 years [percentages are weighted]), representing 3.68 million US residents, 17.0% (95% CI, 15.1%-18.9%) reported undergoing LCS. The prevalence of LCS was lower among non-Hispanic Black than non-Hispanic White individuals but not to a significant degree (12.0% [95% CI, 4.3%-19.7%] vs 17.5% [95% CI, 15.6%-19.5%]; P = .57). Health status was associated with LCS: 468 individuals in poor health vs 96 individuals in excellent health reported LCS (25.2% [95% CI, 20.6%-29.9%] vs 7.6% [95% CI, 5.0%-10.3%]; P < .001), and those with difficulty climbing stairs were more likely to report LCS than those without this functional limitation. Adjusting for sociodemographic factors, functional status, and comorbidities, self-rated health status remained associated with LCS (adjusted odds ratio, 1.19 per each 1-step decline in health; 95% CI, 1.03-1.38), and non-Hispanic Black individuals were 53% less likely to report LCS than non-Hispanic White individuals (adjusted odds ratio, 0.47; 95% CI, 0.24-0.90). Results were robust in sensitivity analyses in which health was alternatively quantified as number of comorbidities. Conclusions and Relevance: LCS in the US is more common among those who may be less likely to benefit from screening because of poor underlying health. Furthermore, racial or ethnic disparities were evident after accounting for health status, with non-Hispanic Black individuals nearly half as likely as non-Hispanic White individuals to report LCS despite the potential for greater benefit of screening this population.

RESUMO

High alcohol intake and breast density increase breast cancer (BC) risk, but their interrelationship is unknown. We examined whether volumetric density modifies and/or mediates the alcohol-BC association. BC cases (n = 2233) diagnosed from 2006 to 2013 in the San Francisco Bay area had screening mammograms 6 or more months before diagnosis; controls (n = 4562) were matched on age, mammogram date, race or ethnicity, facility, and mammography machine. Logistic regression was used to estimate alcohol-BC associations adjusted for age, body mass index, and menopause; interaction terms assessed modification. Percent mediation was quantified as the ratio of log (odds ratios [ORs]) from models with and without density measures. Alcohol consumption was associated with increased BC risk (2-sided P trend = .004), as were volumetric percent density (OR = 1.45 per SD, 95% confidence interval [CI] = 1.36 to 1.56) and dense volume (OR = 1.30, 95% CI = 1.24 to 1.37). Breast density did not modify the alcohol-BC association (2-sided P > .10 for all). Dense volume mediated 25.0% (95% CI = 5.5% to 44.4%) of the alcohol-BC association (2-sided P = .01), suggesting alcohol may partially increase BC risk by increasing fibroglandular tissue.

RESUMO

Vulvovaginal chronic graft-versus-host disease (cGVHD) is an underrecognized complication of stem cell transplantation. Early recognition may prevent severe sequelae. Genital involvement is associated with oral, ocular, and skin manifestations. Treatment includes topical immunosuppression, dilator use, and adjuvant topical estrogen. Clinical and histologic features may mimic other inflammatory vulvar conditions. In the right clinical context, these findings are diagnostic of chronic GVHD. Female recipients of allo-hematopoietic stem cell transplantation (HCT) are at higher risk of condylomas, cervical dysplasia, and neoplasia. The National Institutes of Health publishes guidelines for the diagnosis, grading, management, and supportive care for HCT patients by organ system.

RESUMO

This study aimed to identify facility-level characteristics associated with prevention of mother-to-child HIV transmission service quality. This cross-sectional study sampled 60 health facilities in Mozambique, Côte d'Ivoire, and Kenya (20 per country). Performance score - the proportion of pregnant women tested for HIV in first antenatal care visit, multiplied by the proportion of HIV-positive pregnant women who received appropriate antiretroviral medications - was calculated for each facility using routine data from 2012 to 2013. Facility characteristics were ascertained during on-site visits, including workload. Associations between facility characteristics and performance were quantified using generalized linear models with robust standard errors, adjusting for country. Over six months, facilities saw 38,611 first antenatal care visits in total. On-site CD4 testing, Pima CD4 machine, air conditioning, and low or high (but not mid-level) patient volume were each associated with higher performance scores. Each additional first antenatal care visit per nurse per month was associated with a 4% (95% confidence interval: 1%-6%) decline in the odds that an HIV-positive pregnant woman would receive both HIV testing and antiretroviral medications. Physician workload was only modestly associated with performance. Investments in infrastructure and human resources - particularly nurses - may be critical to improve prevent mother-to-child HIV transmission service delivery and protect infants from HIV.

RESUMO

Recent research suggests that cervical screening of older women is associated with a considerable decrease in cervical cancer incidence. We sought to quantify the efficacy of cervical cytology screening to reduce death from this disease. Among enrollees of 2 US health plans, we compared Papanicolaou smear screening histories of women aged 55-79 years who died of cervical cancer during 1980-2010 (cases) to those of women at risk of cervical cancer (controls). Controls were matched 2:1 to cases on health plan, age, and enrollment duration. Cytology screening during the detectable preclinical phase, estimated as the 5-7 years before diagnosis during which cervical neoplasia is asymptomatic but cytologically detectable, was ascertained from medical records. A total of 39 cases and 80 controls were eligible. The odds ratio of cervical cancer death associated with screening during the presumed detectable preclinical phase was 0.26 (95% confidence interval: 0.10, 0.63) after adjustment for matching characteristics, smoking, marital status, and race/ethnicity using logistic regression. We estimate that cervical cytology screening of all women aged 55-79 years in the United States could avert 630 deaths annually. These results provide a minimum estimate of the efficacy of human papillomavirus DNA screening-a more sensitive test-to reduce cervical cancer death among older women.

RESUMO

Recent guidelines from the American Cancer Society, the American Society for Colposcopy and Cervical Pathology, and the American Society for Clinical Pathology recommend cessation of cervical cancer screening at age 65 years for women with an "adequate" history of negative Papanicolaou smears. In our view, those who formulated these guidelines did not consider a growing body of evidence from nonrandomized studies that provides insight into the efficacy of cervical cancer screening among older women. First, older women are not at indefinitely low risk following negative screening results. Second, recent data from the United States, the United Kingdom, and Sweden suggest that screening of older women is associated with substantial reductions in cervical cancer incidence and mortality, even among previously screened women. It may be that after consideration of the reduced incidence of (and reduced mortality from) cervical cancer that may result from screening older women, the harms and economic costs of screening will be judged to outweigh its benefits. However, it is essential to consider the now-documented benefits of cervical screening when formulating screening guidelines for older women, and recommendations that do not do so will lack an evidence base.
