Associations between Medicaid enrollment and diagnosis stage and survival among pediatric cancer patients.

BACKGROUND: Medicaid-associated disparities in childhood and adolescent (pediatric) cancer diagnosis stage and survival have been reported. However, a key limitation of prior studies is the assessment of health insurance at a single time point. To evaluate Medicaid-associated disparities more robustly, we used Surveillance, Epidemiology, and End Results (SEER)-Medicaid linked data to examine diagnosis stage and survival disparities in those (i) Medicaid-enrolled and (ii) with discontinuous and continuous Medicaid enrollment. METHODS: SEER-Medicaid linked data from 2006 to 2013 were obtained on cases diagnosed from 0 to 19 years. Medicaid enrollment was classified as enrolled versus not enrolled, with further classifications as continuous when enrolled 6 months before through 6 months after diagnosis, and discontinuous when not enrolled continuously for this period. We used multinomial logistic and Cox proportional hazards regression models to determine associations between enrollment measures, diagnosis stage, and cancer death adjusted for covariates. RESULTS: Among 21,502 cases, a higher odds of distant stage diagnoses were observed in association with Medicaid enrollment (odds ratio [OR] = 1.56, 95% confidence interval [CI]: 1.48-1.65), with the highest odds for discontinuous enrollment (OR = 2.0, 95% CI: 1.86-2.15). Among 30,654 cases, any Medicaid enrollment, continuous enrollment, and discontinuous enrollment were associated with 1.68 (95% CI: 1.35-2.10), 1.66 (95% CI: 1.35-2.05), and 1.89 (95% CI: 1.54-2.33) times higher hazards of cancer death versus no enrollment, respectively. CONCLUSIONS: Medicaid enrollment, particularly discontinuous enrollment, is associated with a higher  distant stage diagnosis odds and risk of death. This study supports the critical need for consistent health insurance coverage in children and adolescents.

Facility patient volume and survival among individuals diagnosed with malignant central nervous system tumors.

PURPOSE: Prior research indicates that the volume of central nervous system (CNS) tumor patients seen by a facility is associated with outcomes. However, most studies have focused on short-term survival and specific CNS tumor subtypes. Our objective was to examine whether facility CNS tumor patient volume is associated with longer-term CNS tumor survival overall and by subtype. METHODS: We obtained National Cancer Database (NCDB) data including individuals diagnosed with CNS tumors from 2004 to 2016. Analyses were stratified by age group (0-14, 15-39, 40-64, and ≥ 65 years) and tumor type. We used Cox Proportional Hazards (PH) regression and restricted mean survival time (RMST) analyses to examine associations between survival and facility patient volume percentile category adjusting for potential confounding factors. RESULTS: Our analytic dataset included data from 130,830 individuals diagnosed with malignant first primary CNS tumors. We found a consistently reduced hazard rate of death across age groups for individuals reported by higher vs. lower (> 95th vs. ≤ 70th percentile) volume facilities (hazard ratio (HR)0-14 = 0.78, 95% confidence interval (CI) 0.64-0.95; HR15-39 = 0.87, 95% CI 0.78-0.96; HR40-64 = 0.82, 95% CI 0.76-0.88; HR≥65 = 0.80, 95% CI 0.75-0.86). Significantly longer survival times within 5 years for higher vs. lower volume facilities were observed ranging from 1.20 months (15-39) to 3.08 months (40-64) higher. Associations varied by CNS tumor subtype for all age groups. CONCLUSIONS: These results suggest facility factors influence CNS tumor survival with longer survival for patients reported by higher volume facilities. Understanding these factors will be critical to developing strategies that eliminate modifiable differences in survival times.

Fully Reduced and Mixed-Valent Multi-Copper Aggregates Supported by Tetradentate Diamino Bis(thiolate) Ligands.

Tetradentate diamino bis(thiolate) ligands (l-N2S2(2-)) with saturated linkages between heteroatoms support fully reduced [(Cu(l-N2S2))2Cu2] complexes that bear relevance as an entry point toward molecules featuring the Cu2ICu2II(µ4-S) core composition of nitrous oxide reductase (N2OR). Tetracopper [(Cu(l-N2(SMe2)2))2Cu2] (l-N2(SMe2H)2 = N1,N2-bis(2-methyl-2-mercaptopropane)-N1,N2-dimethylethane-1,2-diamine) does not support clean S atom oxidative addition but undergoes Cl atom transfer from PhICl2 or Ph3CCl to afford [(Cu(l-N2(SMe2)2))3(CuCl)5], 14. When introduced to Cu(I) sources, the l-N2(SArH)2 ligand (l-N2(SArH)2 = N1,N2-bis(2-mercaptophenyl)-N1,N2-dimethylethane-1,2-diamine), made by a newly devised route from N1,N2-bis(2-fluorophenyl)-N1,N2-dimethylethane-1,2-diamine, ultimately yields the mixed-valent pentacopper [(Cu(l-N2SAr2))3Cu2] (19), which has 3-fold rotational symmetry (D3) around a Cu2 axis. The single CuII ion of 19 is ensconced within an equatorial l-N2(SAr)2(2-) ligand, as shown by 14N coupling in its EPR spectrum. Formation of 19 proceeds from an initial, fully reduced product, [(Cu(l-N2SAr2))3Cu2(Cu(MeCN))] (17), which is C2 symmetric and exceedingly air-sensitive. While unreactive toward chalcogen donors, 19 supports reversible reduction to the all-cuprous state; generation of [19]1- and treatment with S atom donors only return 19 because structural adjustments necessary for oxidative addition are noncompetitive with outer-sphere electron transfer. Oxidation of 19 is marked by intense darkening, consistent with greater mixed valency, and by dimerization in the crystalline state to a decacopper species ([20]2+) of S4 symmetry.

Risk of suicide among individuals with a history of childhood cancer.

BACKGROUND: Previous studies have described suicidal ideation among survivors of childhood cancer, but small numbers of events limit the understanding of suicide risk. The objectives of this study were to assess whether childhood cancer survivors are at increased risk of suicide in comparison with the general population and to determine risk factors associated with risk in a population-based cohort. METHODS: First primary malignancies among individuals aged 0 to 19 years from 1975 to 2016 were identified from Surveillance, Epidemiology, and End Results (SEER) databases. Standardized mortality ratios (SMRs) of suicide were obtained via SEER*Stat software from SEER 9. Fine and Gray proportional hazards models were used to identify suicide-associated factors among childhood cancer patients included in SEER 18. RESULTS: In all, 96,948 childhood cancer cases and 89 suicides were identified. Across all attained ages, the suicide risk for individuals with a childhood cancer history (11.64 per 100,000 person-years) was similar to the risk for those without a cancer history (SMR, 1.14; 95% confidence interval [CI], 0.91-1.43). However, for survivors alive beyond the age of 28 years (the median age of death by suicide), the suicide risk was significantly elevated (suicides per 100,000 person-years, 22.43; SMR, 1.40; 95% CI, 1.02-1.87). Females (hazard ratio, 0.29; 95% CI, 0.18-0.59; P < .01) had lower risks than males. CONCLUSIONS: These results suggest that long-term childhood cancer survivors may be at increased suicide risk. Male sex is an independent risk factor for suicide. However, the absolute risk of suicide in older survivors is still low at ~1 per 5000 person-years. Future efforts should identify survivorship strategies to mitigate suicide risk.

Associations between geographic residence and US adolescent and young adult cancer stage and survival.

BACKGROUND: Multiple studies have indicated that place of residence can influence cancer survival; however, few studies have specifically focused on geographic factors and outcomes in adolescents and young adults (AYAs) with cancer. The objective of this study was to evaluate evidence for geographic disparities in cancer diagnosis stage and overall survival in AYAs and to examine whether stage mediated survival associations. METHODS: National Cancer Database data on AYAs aged 15 to 39 years who were diagnosed with cancer from 2010 to 2014 were obtained. Residence in Metropolitan (metro), urban, or rural counties at the time of diagnosis was defined using Rural-Urban Continuum Codes. Distance between the patient's residence and the reporting hospital was classified as short (≤2.5 miles), intermediate (>12.5 to <50 miles), or long (≥50 miles). Logistic and Cox proportional hazards regression models were used for analyses. RESULTS: The stage and survival analyses included 146,418 and 178,688 AYAs, respectively. The odds of a late versus early stage at diagnosis (stages III and IV vs I and II) were 1.16 (95% CI, 1.05-1.29) times greater for AYAs living in rural versus metro counties and 1.20 (95% CI, 1.16-1.25) times greater for AYAs living at long versus short distances to the reporting hospital. The hazard of death was 1.17 (95% CI, 1.05-1.31) and 1.30 (95% CI, 1.25-1.36) times greater for those living in rural versus metro counties, respectively, and for long versus short distances to the reporting hospital, respectively. Disease stage mediated 54% and 31% of the associations between metro, urban, or rural residence and residential distance categories and survival. CONCLUSIONS: Rural residence and living long distances from the reporting hospital were associated with later stage diagnoses and lower survival in AYAs with cancer. Further research is needed to understand mechanisms. LAY SUMMARY: Adolescents and young adults (AYAs) with cancer are a vulnerable population because cancer is of low suspicion in this population and may not be diagnosed in a timely manner. The authors evaluated evidence for geographic disparities in cancer stage at diagnosis and survival in the AYA population. The findings indicate that AYAs living in rural versus metropolitan US counties and those living farther from the diagnosis reporting hospital are more likely to be diagnosed at a later cancer stage, when it is generally less treatable, and have lower survival compared with AYAs living in metropolitan counties.

Residential distance from the reporting hospital and survival among adolescents, and young adults diagnosed with CNS tumors.

PURPOSE: Prior research shows that residential distance to a treatment facility may be an important factor in central nervous system (CNS) tumor outcomes. Our goal was to examine residential distance to the reporting hospital and overall survival in adolescents and young adults (AYA) diagnosed with CNS tumors. METHODS: National Cancer Database data on AYA 15-39 years old diagnosed with CNS and Other Intracranial and Intraspinal Neoplasms (CNS tumors) from 2010 to 2014 were obtained. Distance between the case's residence at diagnosis or initial treatment and the reporting hospital was classified in miles as short (≤ 12.5), intermediate (> 12.5 and < 50), and long (≥ 50). Cox proportional hazards regression models were used for analyses. RESULTS: Among 9335 AYA diagnosed with CNS tumors, hazard ratios (HRs) were 1.06 (95% CI 0.96-1.17) and 0.82 (95% CI 0.73-0.93) for those with residences at intermediate and long vs. short distances, respectively, after adjusting for age, sex, race/ethnicity, and zip-code level education and income. After adjusting for the facility volume of CNS tumor patients, the association was attenuated for long vs. short distance residences (HR 0.92, 95% CI 0.81-1.04). The HRs varied by tumor type, race/ethnicity, and zip-code level income with significantly lower hazards of death for those with residences at long vs. short distances for low-grade astrocytic tumors, ependymomas, non-Hispanic Whites, and those from higher-income areas. CONCLUSIONS: Living at long distances for CNS tumor care may be associated with better survival in AYA patients. This may be explained by travel to facilities with more experience treating CNS tumors.

Impact of the Patient Protection and Affordable Care Act on cost-related medication underuse in nonelderly adult cancer survivors.

BACKGROUND: Cost-related medication underuse (CRMU), a measure of access to care and financial burden, is prevalent among cancer survivors. The authors quantified the impact of the Patient Protection and Affordable Care Act (ACA) on CRMU in nonelderly cancer survivors. METHODS: Using National Health Interview Survey data (2011-2017) for cancer survivors aged 18 to 74 years, the authors estimated changes in CRMU (defined as taking medication less than prescribed due to costs) before (2011-2013) to after (2015-2017) implementation of the ACA. Difference-in-differences (DID) analyses estimated changes in CRMU after implementation of the ACA in low-income versus high-income cancer survivors, and nonelderly versus elderly cancer survivors. RESULTS: A total of 6176 cancer survivors aged 18 to 64 years and 4100 cancer survivors aged 65 to 74 years were identified. In DID analyses, there was an 8.33-percentage point (PP) (95% confidence interval, 3.06-13.6 PP; P = .002) decrease in CRMU for cancer survivors aged 18 to 64 years with income <250% of the federal poverty level (FPL) compared with those with income >400% of the FPL. There was a reduction for cancer survivors aged 55 to 64 years compared with those aged 65 to 74 years with income <400% of the FPL (-9.35 PP; 95% confidence interval, -15.6 to -3.14 PP [P = .003]). CONCLUSIONS: There was an ACA-associated reduction in CRMU noted among low-income, nonelderly cancer survivors. The ACA may improve health care access and affordability in this vulnerable population.

Impact of the affordable care act dependent coverage provision on young adult cancer patient insurance coverage by sociodemographic and economic characteristics.

PURPOSE: To evaluate the impact of the Affordable Care Act Dependent Care Provision by sociodemographic and economic characteristics in young adult cancer patients. METHODS: The National Cancer Database (NCDB) and the Surveillance, Epidemiology, and End Results (SEER) 18 database were queried for young adult cancer cases diagnosed during 2007-2014. Using a difference-in-differences approach, we examined insurance coverage in different subgroups of policy-eligible 19-25 year-olds versus policy-ineligible 27-29 year-olds from the pre- (2007-2009) to post- (2011-2014) Dependent Care Provision period. RESULTS: Across subgroups and study populations, insurance coverage increased significantly following the Provision enactment in the policy-eligible versus policy-ineligible group across most subgroups (range in NCDB: 1.83 to 6.38% for low and mid-low education areas, respectively; range in SEER: 1.43 to 6.18 for Non-Hispanic Others and Hispanics, respectively). Heterogenous impacts were observed by sex with a larger impact in males (NCDB: 5.14%, 95% CI 3.59-6.69; SEER: 4.46, 2.12-6.8) than females (NCDB: 2.51%, 95% CI 1.39-3.62; SEER: 2.50, 0.82-4.18). We observed no other statistical evidence for Dependent Care Provision subgroup heterogeneity except for a smaller impact in individuals from low education areas in NCDB. CONCLUSIONS: Our results indicate a positive Dependent Care Provision impact on insurance coverage in young adults with cancer across subgroups, with evidence for a smaller impact in females relative to males and in low relative to high education areas.

Outcomes of renal salvage for penetrating renal trauma: a single institution experience.

INTRODUCTION: Conservative management of penetrating renal trauma is emerging, with data originating from centers with variable level of trauma care. This study reviews the outcomes of renal salvage after penetrating trauma at a level I trauma center. MATERIALS AND METHODS: An institutional review board approved trauma registry at Saint Louis University Hospital was retrospectively analyzed, for patients with penetrating renal trauma from 2009 to 2014. Patients were divided into nephrectomy group (NG) or non-nephrectomy group (non-NG), and compared. A multi-variable analysis was performed to determine predictors of nephrectomy, with cross validation to evaluate the performance of the multi-variable model. Data was analyzed using R version 3.3.2. A p value of < 0.05 was considered as significant. RESULTS: A total of 121 patients were identified with penetrating renal trauma. Gunshot injury was the leading cause of injury (87%). Eighteen (15%) patients required nephrectomy. The overall mean injury severity score (ISS). was 20. High grade (grade 4-5) renal injuries were noted in 41 patients (34%). Among these, 14 patients (34%) underwent a nephrectomy, while 27 patients (66%) were managed conservatively to salvage renal units. CT grade of renal injury was the only predictor of nephrectomy, on multi-variable analysis (OR 17.09 CI 2.75-105.99, p = 0.002). CT grade of injury and injury severity score were predictors of endoscopic intervention on a sub group analysis of non-NG. CONCLUSIONS: CT grade of injury predicts nephrectomy after penetrating renal trauma. Conservative management is a feasible option in penetrating renal trauma even with a higher grade of injury.

MACRA Meets Your Revenue Cycle: Four Steps for the Value Journey.

The shift from fee-for-service to value-based reimbursement models represents one of the biggest billing transitions and greatest financial opportunities for physician practices. On the heels of ICD-10 adoption and against the backdrop of new digital infrastructure and workflows, practices face a new journey toward the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) and the Quality Payment Program. Knowledge of how to traverse the path, navigate the intersections, and optimize the opportunities of healthcare payment reform is essential. This article offers an overview of the new Medicare reimbursement landscape and specific steps that practices can take to protect revenue streams today and ensure they thrive tomorrow.

Global "omics" evaluation of human placental responses to preeclamptic conditions.

BACKGROUND: Preeclampsia (PE) is a leading cause of maternal death. Its cause is still debated but there is general agreement that the placenta plays a central role. Perhaps the most commonly proposed contributors to PE include placental hypoxia, oxidative stress, and increased proinflammatory cytokines. How the placenta responds to these abnormalities has been considered but not as part of a comprehensive analysis of low-molecular-weight biomolecules and their responses to these accepted PE conditions. OBJECTIVE: Using a peptidomic approach, we sought to identify a set of molecules exhibiting differential expression in consequence of provocative agents/chemical mediators of PE applied to healthy human placental tissue. STUDY DESIGN: Known PE conditions were imposed on normal placental tissue from 13 uncomplicated pregnancies and changes in the low-molecular-weight peptidome were evaluated. A t test was used to identify potential markers for each imposed stress. These markers were then submitted to a least absolute shrinkage and selection operator multinomial logistic regression model to identify signatures specific to each stressor. Estimates of model performance on external data were obtained through internal validation. RESULTS: A total of 146 markers were increased/decreased as a consequence of exposure to proposed mediators of PE. Of these 75 changed with hypoxia; 23 with hypoxia-reoxygenation/oxidative stress and 48 from exposure to tumor necrosis factor-α. These markers were chemically characterized using tandem mass spectrometry. Identification rates were: hypoxia, 34%; hypoxia-reoxygenation, 60%; and tumor necrosis factor-α, 50%. Least absolute shrinkage and selection operator modeling specified 16 markers that effectively distinguished all groups, ie, the 3 abnormal conditions and control. Bootstrap estimates of misclassification rates, multiclass area under the curve, and Brier score were 0.108, 0.944, and 0.160, respectively. CONCLUSION: Using this approach we found previously unknown molecular changes in response to individual PE conditions that allowed development biomolecular signatures for exposure to each accepted pathogenic condition.

Purkinje cell ataxin-1 modulates climbing fiber synaptic input in developing and adult mouse cerebellum.

Previous studies indicate that while transgenic mice with ATXN1[30Q]-D776-induced disease share pathological features caused by ATXN1[82Q] having an expanded polyglutamine tract, they fail to manifest the age-related progressive neurodegeneration seen in spinocerebellar ataxia type 1. The shared features include morphological alterations in climbing fiber (CF) innervation of Purkinje cells (PCs). To further investigate the ability of ataxin-1 (ATXN1) to impact CF/PC innervation, this study used morphological and functional approaches to examine CF/PC innervation during postnatal development in ATXN1[30Q]-D776 and ATXN1[82Q] cerebella. Notably, ATXN1[30Q]-D776 induced morphological alterations consistent with the development of the innervation of PCs by CFs being compromised, including a reduction of CF translocation along the PC dendritic tree, and decreased pruning of CF terminals from the PC soma. As previously shown for ATXN1[82Q], ATXN1[30Q]-D776 must enter the nucleus of PCs to induce these alterations. Experiments using conditional ATXN1[30Q]-D776 mice demonstrate that both the levels and specific timing of mutant ATXN1 expression are critical for alteration of the CF-PC synapse. Together these observations suggest that ATXN1, expressed exclusively in PCs, alters expression of a gene(s) in the postsynaptic PC that are critical for its innervation by CFs. To investigate whether ATXN1[30Q]-D776 curbs the progressive disease in ATXN1[82Q]-S776 mice, we crossed ATXN1[30Q]-D776 and ATXN1[82Q]-S776 mice and found that double transgenic mice developed progressive PC atrophy. Thus, the results also show that to develop progressive cerebellar degeneration requires expressing ATXN1 with an expanded polyglutamine tract.

The impact of individual-level income predicted from the BRFSS on the association between insurance status and overall survival among adults with cancer from the SEER program.

INTRODUCTION: Among patients with cancer in the United States, Medicaid insurance is associated with worse outcomes than private insurance and with similar outcomes as being uninsured. However, prior studies have not addressed the impact of individual-level socioeconomic status, which determines Medicaid eligibility, on the associations of Medicaid status and cancer outcomes. Our objective was to determine whether differences in cancer outcomes by insurance status persist after accounting for individual-level income. METHODS: The Surveillance, Epidemiology, and End Results (SEER) database was queried for 18-64 year-old individuals with cancer from 2014-2016. Individual-level income was imputed using a model trained on Behavioral Risk Factors Surveillance Survey participants including covariates also present in SEER. The association of 1-year overall survival and insurance status was estimated with and without adjustment for estimated individual-level income and other covariates. RESULTS: A total of 416,784 cases in SEER were analyzed. The 1-yr OS for patients with private insurance, Medicaid insurance, and no insurance was 88.7%, 76.1%, and 73.7%, respectively. After adjusting for all covariates except individual-level income, 1-year OS differences were worse with Medicaid (-6.0%, 95% CI = -6.3 to -5.6) and no insurance (-6.7%, 95% CI = -7.3 to -6.0) versus private insurance. After also adjusting for estimated individual-level income, the survival difference for Medicaid patients was similar to privately insured (-0.4%, 95% CI = -1.9 to 1.1) and better than uninsured individuals (2.1%, 95% CI = 0.7 to 3.4). CONCLUSIONS: Income, rather than Medicaid status, may drive poor cancer outcomes in the low-income and Medicaid-insured population. Medicaid insurance coverage may improve cancer outcomes for low-income individuals.

Soluble and insoluble lysates from the human A53T mutant α-synuclein transgenic mouse model induces α-synucleinopathy independent of injection site.

Pathological aggregation of a-synuclein (aS) is implicated in the pathogenesis of Parkinson's disease (PD) and other a-synucleinopathies. The current view is that neuron-to-neuron spreading of aS pathology contributes to the progression of a-synucleinopathy. We used an A53T mutant human aS transgenic mouse model (TgA53T) to examine whether the site of pathogenic aS inoculation affects the pattern of neuropathology and whether soluble and insoluble fractions derived from crude pathogenic tissue lysates exhibit differential capacities to initiate aS pathology. To test whether the inoculation site impacts the ultimate spatial/temporal patterns of aS pathology, aS preformed fibrils (PFF), or brain homogenates from TgA53T mice with a-synucleinopathy, were injected into the cortex/striatum, brain stem, or skeletal muscle. In all cases, inoculation of pathogenic aS induced end-stage motor dysfunction within ~100 days post-inoculation (dpi). Significantly, irrespective of the inoculation sites, ultimate distribution of the aS pathology was like that seen in normally aged TgA53T mice at end-stage, indicating that the intrinsic neuronal vulnerability is a significant determinant in the induction of aS pathology, even when initiated by inoculation of pathogenic aS. Temporal analysis of brain stem injected TgA53T mice show that initial aS pathology was seen by 30 days post-inoculation and inflammatory changes occur at later stages. To determine if the aS species with differential solubility are differentially pathogenic, brain lysates from end-stage TgA53Tmice were fractionated into highly soluble (S150) and insoluble (P150) fractions, as well as the endoplasmic reticulum (ER)-enriched fraction (P100). Significantly, all fractions were able to seed de novo aS pathology in vivo, when injected unilaterally into TgA53Tmice with the ER fractions being most pathogenic. Our results suggest that multiple aS species from brain can initiate the development of progressive aS pathology.

Impact of COVID-19 pandemic on breast cancer screening in a large midwestern United States academic medical center.

BACKGROUND: Access to breast screening mammogram services decreased during the COVID-19 pandemic. Our objectives were to estimate: 1) the COVID-19 affected period, 2) the proportion of pandemic-associated missed or delayed screening encounters, and 3) pandemic-associated patient attrition in screening encounters overall and by sociodemographic subgroup. METHODS: We included screening mammogram encounter EPIC data from 1-1-2019 to 12-31-2022 for females ≥40 years old. We used Bayesian State Space models to describe weekly screening mammogram counts, modeling an interruption that phased in and out between 3-1-2020 and 9-1-2020. We used the posterior predictive distribution to model differences between a predicted, uninterrupted process and the observed screening mammogram counts. We estimated associations between race/ethnicity and age group and return screening mammogram encounters during the pandemic among those with 2019 encounters using logistic regression. RESULTS: Our analysis modeling weekly screening mammogram counts included 231,385 encounters (n = 127,621 women). Model-estimated screening mammograms dropped by >98% between 03-15-2020 and 05-24-2020 followed by a return to pre-pandemic levels or higher with similar results by race/ethnicity and age group. Among 79,257 women, non-Hispanic (NH) Asians, NH Blacks, and Hispanics had significantly (p < .05) lower odds of screening encounter returns during 2020-2022 vs. NH Whites with odds ratios (ORs) from 0.70 to 0.91. Among 79,983 women, those 60-69 had significantly higher odds of any return screening encounter during 2020-2022 (OR = 1.28), while those ≥80 and 40-49 had significantly lower odds (ORs 0.77, 0.45) than those 50-59 years old. A sensitivity analysis suggested a possible pre-existing pattern. CONCLUSIONS: These data suggest a short-term pandemic effect on screening mammograms of ~2 months with no evidence of disparities. However, we observed racial/ethnic disparities in screening mammogram returns during the pandemic that may be at least partially pre-existing. These results may inform future pandemic planning and continued efforts to eliminate mammogram screening disparities.

Associations of State Supplemental Nutrition Assistance Program Eligibility Policies With Mammography.

PURPOSE: The Supplemental Nutrition Assistance Program (SNAP) addresses food insecurity for low-income households, which is associated with access to care. Many US states expanded SNAP access through policies eliminating the asset test (ie, restrictions based on SNAP applicant assets) and/or broadening income eligibility. The objective of this study was to determine whether state SNAP policies were associated with the use of mammography among women eligible for breast cancer screening. METHODS: Data for income-eligible women 40 to 79 years of age were obtained from the 2006 to 2019 Behavioral Risk Factor Surveillance System. Difference-in-differences analyses were conducted to compare changes in the percentage of mammography in the past year from pre- to post-SNAP policy adoption (asset test elimination or income eligibility increase) between states that and did not adopt policies expanding SNAP eligibility. RESULTS: In total, 171,684 and 294,647 income-eligible female respondents were included for the asset test elimination policy and income eligibility increase policy analyses, respectively. Mammography within 1 year was reported by 58.4%. Twenty-eight and 22 states adopted SNAP asset test elimination and income increase policies, respectively. Adoption of asset test elimination policies was associated with a 2.11 (95% confidence interval [CI], 0.07-4.15; P = .043) percentage point increase in mammography received within 1 year, particularly for nonmetropolitan residents (4.14 percentage points; 95% CI, 1.07-7.21 percentage points; P = .008), those with household incomes <$25,000 (2.82 percentage points; 95% CI, 0.68-4.97 percentage points; P = .01), and those residing in states in the South (3.08 percentage points; 95% CI, 0.17-5.99 percentage points; P = .038) or that did not expand Medicaid under the Patient Protection and Affordable Care Act (3.35 percentage points; 95% CI, 0.36-6.34; P = .028). There was no significant association between mammography and state-level policies broadening of SNAP income eligibility. CONCLUSIONS: State policies eliminating asset test requirements for SNAP eligibility were associated with increased mammography among low-income women eligible for breast cancer screening, particularly for those in the lowest income bracket or residing in nonmetropolitan areas or Medicaid nonexpansion states.

Inpatient Care and Outcomes Among People With Cancer Experiencing Homelessness.

Importance: Cancer is a leading cause of death among people experiencing homelessness (PEH) in the US. Acute care settings are important sources of care for PEH; however, the association of housing status with inpatient care remains understudied, particularly in the context of cancer. Objective: To assess whether housing status is associated with differences in the inpatient care of hospitalized adults with cancer. Design, Setting, and Participants: This cross-sectional study included hospitalized inpatient adults aged 18 years or older diagnosed with cancer who were identified using data from the 2016 to 2020 National Inpatient Sample. Propensity score matching was used to create a cohort of PEH and housed individuals matched according to age, sex, race and ethnicity, insurance type, cancer diagnosis, number of comorbidities, substance use disorder, severity of illness, year of admission, hospital location, hospital ownership, region, and hospital bed size. Matched pairs were identified using a 1:1 nearest neighbor matching algorithm without replacement, accounting for survey weights. Data were analyzed from August 1, 2022, to April 30, 2024. Exposure: Housing status. Main Outcomes and Measures: The associations of receipt of invasive procedures, systemic therapy, or radiotherapy during hospitalization (primary outcomes) as well as inpatient death, high cost of stay, and discharge against medical advice (AMA) (secondary outcomes) with housing status. Odds ratios and 95% CIs were estimated with multivariable logistic regression, with adjustment for patient, disease, and hospital characteristics of the matched cohort. Results: The unmatched cohort comprised 13 838 612 individuals (median [IQR] age, 67 [57-76] years; 7 329 473 males [53.0%]) and included 13 793 462 housed individuals (median [IQR] age, 68 [58-77] years) and 45 150 (median [IQR] age, 58 [52-64] years) individuals who were experiencing homelessness after accounting for survey weights. The PEH cohort had a higher prevalence of lung (17.3% vs 14.5%) and upper gastrointestinal (15.2% vs 10.5%) cancers, comorbid substance use disorder (70.2% vs 15.3%), and HIV (5.3% vs 0.5%). Despite having higher rates of moderate or major illness severity (80.1% vs 74.0%) and longer length of stay (≥5 days: 62.2% vs 49.1%), PEH were less likely to receive invasive procedures (adjusted odds ratio [AOR], 0.53; 95% CI, 0.49-0.56), receive systemic therapy (AOR, 0.73; 95% CI, 0.63-0.85), or have a higher-than-median cost of stay (AOR, 0.71; 95% CI, 0.65-0.77). Although PEH had lower rates of inpatient death (AOR, 0.79; 95% CI, 0.68-0.92), they were 4 times more likely to be discharged AMA (AOR, 4.29; 95% CI, 3.63-5.06). Conclusions and Relevance: In this nationally representative cross-sectional study of hospitalized adults with cancer, disparities in inpatient care of PEH highlight opportunities to promote equitable cancer care in this socioeconomically vulnerable population.

Trends and factors associated with receipt of human papillomavirus (HPV) vaccine in private, public, and alternative settings in the United States.

BACKGROUND: One of the goals of the President's Cancer Panel was to maximize access to human papillomavirus (HPV) vaccination through expansion of alternative settings for receiving the vaccine, such as in public health settings, schools, and pharmacies. METHODS: In a cross-sectional analysis, we utilized the National Immunization Survey-Teen data from 2014 to 2020 (n = 74,645) to describe trends and factors associated with HPV vaccine uptake in private, public, and alternative settings. We calculated annual percent change (APC) between 2014 and 2020, estimating rate of HPV vaccine uptake across settings. Using multinomial logistic regression, we estimated the odds of receipt of HPV vaccine in public health settings and other alternative settings compared to private healthcare settings, adjusting for sociodemographic covariates. RESULTS: We found a 5 % annual increase in the use of private facilities between 2014-2018 (APC = 5.3; 95 % CI 3.4, 7.1), and almost 7 % between 2018-2020 (APC = 6.7; 95 % CI 1.4, 12.3). Adjusted multinomial logistic regression analyses found that odds of receiving vaccinations at a public facility vs. a private facility increased almost two times for adolescents living below poverty (aOR = 1.82, 95 % CI: 1.60, 2.08) compared to above poverty. Additionally, adolescents without physician recommendations had lower odds of receiving vaccines at public versus private facilities (aOR = 1.75, 95 % CI: 1.44, 2.12). Finally, odds of receiving HPV vaccines at public facilities vs. private facilities decreased by 33 % for White adolescents (aOR = 0.67, 95 % CI: 0.57, 0.78) versus Black adolescents. CONCLUSIONS: Sociodemographic factors such as race, and socioeconomic factors such as poverty level, and receipt of physician HPV recommendations are associated with receiving the vaccine at private settings vs. public health facilities and alternative settings. This information is important in strengthening alternative settings for HPV vaccine uptake to increase access to the vaccine among disadvantaged individuals.
