Associations of neighborhood deprivation with breast cancer tumor genomics, targeted treatment use, and survival.

PURPOSE: Neighborhood environments appear to influence breast cancer biology and outcomes. This study evaluated somatic, treatment, and outcome differences by Area Deprivation Index in patients with metastatic breast cancer. METHODS: Retrospective, population-based cohort study using clinical and genomic data gathered between 2015 and 2024 at four academic institutions in the United States. The outcomes were differences in circulating tumor DNA mutation profiles, PI3K inhibitor use, and survival between patients with metastatic breast cancer living in high deprivation (Area Deprivation Index ≥ 60 by national rank) and low deprivation (< 60) neighborhoods. RESULTS: Among 1127 patients with metastatic breast cancer, 335 (29.7%) lived in high deprivation areas. These patients were more likely to have TP53 mutations (Odds ratio 1.49, 95% Confidence Interval 1.07-2.08, P = 0.018). Among hormone receptor-positive, HER2-negative patients eligible for PI3K inhibitors, those from high deprivation areas were less likely to receive them (17.4% vs. 36.7%, p = 0.02). Median survival from the time of circulating tumor DNA testing was significantly shorter in the high deprivation group (24 months versus 28 months, p = 0.04) and for Black patients in the high deprivation group versus Black patients in low deprivation group and all White patients (15 months versus 25-28 months, p = 0.02). CONCLUSIONS: We found that patients with metastatic breast cancer living in high deprivation neighborhoods were more likely to have TP53 mutations, an indicator of aggressive disease biology, less likely to receive PI3K inhibitors, and had shorter overall survival compared to patients living in low deprivation neighborhoods by Area Deprivation Index.

Neighborhood Deprivation and Screening Mammography Utilization: A Retrospective Cross-Sectional Study.

RATIONALE AND OBJECTIVES: Access to screening mammography reduces breast cancer mortality disparities. The Area Deprivation Index (ADI) is a validated measure of neighborhood socioeconomic disadvantage linked to adverse health outcomes. There is limited data evaluating mammography utilization among patients residing in areas of higher deprivation. This study evaluated the association between ADI and screening mammography utilization within an accountable care organization (ACO) affiliated with a multicenter academic medical center in the Upper Midwest. METHODS: This retrospective cross-sectional study included women aged 40-85 years attributed to the ACO in 2022, based on Wisconsin Collaborative for Healthcare Quality criteria. The primary outcome was receipt of screening mammography within two years. The primary exposure was ADI, analyzed by decile (ordinal) and as low (deciles 1-5) versus high (deciles 6-10) deprivation. The logistic regression models evaluated associations between ADI and screening, unadjusted and adjusted for age, race, ethnicity, and preferred language. RESULTS: Among 7463 participants with geographic data, 74.4% completed screening. Screening rates were 75.7% in low-deprivation areas versus 66.2% in high-deprivation areas. Increasing ADI decile was associated with reduced screening in unadjusted (OR 0.891, 95% CI 0.87-0.91, p<0.001) and adjusted analyses (OR 0.897, 95% CI 0.88-0.92, p<0.001). Black participants (OR 0.444, p<0.001) and individuals preferring non-English languages (OR 0.333, p<0.001) had lower screening odds after adjustment. CONCLUSION: Higher neighborhood deprivation is independently associated with lower screening mammography utilization. Targeted, equity-focused interventions addressing neighborhood, racial, and language-related barriers are needed to reduce screening disparities.

Children of imprisoned fathers.

John Bowlby's influential 1951 World Health Organization monograph, Maternal Care and Mental Health, pointed to a causal relationship between loss of maternal care and disturbed personality development, and had a profound effect on psychiatrists' thinking about antisocial behavior in particular, and character formation in general. More recently, psychiatric investigators have been increasingly interested in the effects of a child separation from his father. This has been stimulated by sociological concerns for one-parent, fatherless families (Adams, 1973) and by our realizing how historically neglected has been the paternal role in theories of child development. Herzog and Sudia (1971) have recently compiled an extensive bibliography of the fatherless family. Numerous clinical studies of loss of the father, through death (Nagera, 1970; Wolfenstein, 1966; Bonnard, 1964), suicide (Cain and Fast 1966), divorce (McDermott, 1970), military service (Crumley and Blumenthal, 1973), occupations (Rosenfeld et al., 1973), desertion (Thomes, 1968), and mental hospitalization (Schiff, 1965), have all reported various adverse effects, particularly on male children. It has been difficult, however, to sort out the effects of the loss itself from more general prevailing and prior family relationships. My interest in this subject was quickened when I began to see boys brought to a neighborhood clinic for aggressive and antisocial behavior soon after their fathers were imprisoned. I was impressed by the lack of reports in the literature on this form of father separation. I am presenting here my clinical observations of six families seen over a three-year period as part of a general child psychiatric experience at a comprehensive neighborhood health center sponsored by the Massachusetts General Hospital in Boston. Although there are obvious selection biases that limit generalization when families referred to psychiatrists are the only source of information, it seems a useful place to begin an examination of the consequences for children of father-separation as a result of imprisonment.

The association between neighbourhood marginalization and SARS-CoV-2 outcomes in patients presenting to emergency departments.

OBJECTIVE: Social and economic marginalizations have been associated with inferior health outcomes in Canada. Our objective was to describe the relationship between neighbourhood marginalization and COVID-19 outcomes among patients presenting to Canadian emergency departments (ED). METHODS: We conducted an observational study among consecutive COVID-19 patients recruited from 47 hospitals participating in the Canadian COVID-19 ED Rapid Response Network (CCEDRRN) between March 3, 2020, and July 24, 2022. We linked data with the Canadian Marginalization Index (CAN-Marg). We used multivariable, multi-level logistic regression models to understand the association between dimensions of neighbourhood marginalization, and severe COVID-19 and in-hospital mortality. RESULTS: There were 55,588 eligible patients. Those from neighbourhoods with a higher proportion of recent immigrants (OR = 0.86 per unit increase [0.81, 0.92]), lower workforce participation (OR = 0.84 per unit increase [0.75, 0.94]), and more housing insecurity (OR = 0.81 per unit increase [0.77, 0.86]) were less likely to present to EDs with severe COVID-19. However, patients from materially marginalized neighbourhoods had increased odds of dying in hospital (OR = 1.19 per unit increase [95% CI 1.09, 1.30]) compared to patients from less materially marginalized neighbourhoods. Patients living in neighbourhoods with a higher proportion of recent immigrants (OR = 0.83 per unit increase [0.78, 0.91]) and lower participation in the workforce (OR = 0.77 per unit increase [0.66, 0.87]) experienced lower odds of dying. CONCLUSION: Despite no association with severe COVID-19 at ED presentation, the only marginalization domain associated with in-hospital mortality was material deprivation. Our findings present insights on ED-seeking behaviour, hospital access, and care that population studies could not.

The effect of outreach workers' educational efforts on disadvantaged preschool children's use of preventive services.

A special program of outreach services was implemented to assist a poverty population to appropriately use health services in the Kaiser-Permanente Medical Care Program. A study was conducted to determine the effect of outreach workers' intervention on the use of preventive services by this population. Intially, families were divided into two groups, one with and one without outreach workers. Outreach workers (neighborhood health coordinators) were trained in prevention and health education. They were then assigned to specific subgroups of the poverty population to teach the importance of preventive services and to motivate persons to use these services. This paper focuses on the effect of outreach workers' services on the use of selected preventive care services (immunizations and tine test) by preschool children from poverty families. Preschool children in families with coordinator services had higher use rates for preventive care. The sub-group for which outreach workers were specially trained to focus on preventive procedures for the pre-school group had markedly higher use rates for preventive care. The findings suggest that special intervention programs, using indigenous and nonprofessional outreach workers, can increase preventive service utilization by poverty groups.
