Patient-reported experiences with direct acting antiviral therapy in an integrated model of hepatitis C care in homeless shelters. J Viral Hepat 2021; 28:1488-1490. [PMID: 34003525 PMCID: PMC8574070 DOI: 10.1111/jvh.13544] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 03/18/2021] [Accepted: 04/19/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIM: Patient reported experience (PRE) is critical for engagement in hepatitis C (HCV) therapy in hard to reach populations. However, there is no data on patient reported experience with DAA therapy among homeless patients accessing shelters. We assessed PRE with DAA treatment following implementation of HCV therapy within homeless shelters in two diverse regions in the United States. METHODS: In a study of integrated HCV testing and treatment in four homeless shelters in San Francisco (SF) and Minnesota (MN), 66 patients received DAA therapy from 11/2018–4/2020. PREs were assessed at the end of therapy with constructs: satisfaction with communication with their HCV treatment provider, receipt of social support during therapy, perceived stigma associated with HCV infection, and their overall satisfaction with DAA therapy. Descriptive statistics and factors associated with satisfaction with HCV therapy were assessed. RESULTS: At end of therapy, 41 patients completed the questionnaire (response rate was 62%). Median age was 56 years, 74.4% were men, 44% White (45% Black, 6% Latino), 35% had more than a high school diploma, 65% had a history of IV drug use, 56% had received SUD treatment, and 12% were co-infected with HIV. During DAA treatment, the majority of patients lived in shelters, 37% used illicit drugs, 24% consumed alcohol, and 14% received psychiatric treatment. Patient reported experience with DAA therapy were as follows: 100% agreed or strongly agreed that HCV providers seemed non-judgmental, 98% reported that their provider seemed to care about them, 98% reported that people close to them had been supportive of their care, and 98% were satisfied with their HCV treatment. There were no patient level or clinical predictors associated with PREs of stigma, perceived lack of social support or satisfaction with DAA treatment. CONCLUSIONS: Nearly all (>95%) homeless patients receiving integrated HCV testing and therapy within homeless shelters felt supported and reported favorable views toward their providers and a high level of satisfaction with DAA treatment. As patient reported experience is key for engagement in HCV therapy, our onsite treatment intervention within shelters can serve as a model of HCV care to enhance treatment uptake in patients experiencing homelessness.

Abstract
BACKGROUND Rural populations experience several disparities, influenced by structural-, community-, and individual-level barriers, across the breast and cervical cancer continuum. OBJECTIVES This study seeks to identify structural-, community-, and individual-level barriers that affect rural populations across the cancer continuum, understand the role of nurses serving rural populations in breast and cervical cancer screening and diagnostics, and provide recommendations for working with rural patients. METHODS This is a secondary analysis of qualitative interviews conducted with public health nurses serving rural populations. FINDINGS Emergent themes indicate that rural populations experience barriers that affect disparities across the breast and cervical cancer continuum, including a changing healthcare landscape, access to cancer-focused care, access to insurance, collective poverty, and demographic factors. Nurses working with rural communities can address these disparities as they fulfill multiple roles and responsibilities.

Abstract
BACKGROUND Though artificial intelligence (AI) has the potential to augment the patient-physician relationship in primary care, bias in intelligent health care systems has the potential to differentially impact vulnerable patient populations. OBJECTIVE The purpose of this scoping review is to summarize the extent to which AI systems in primary care examine the inherent bias toward or against vulnerable populations and appraise how these systems have mitigated the impact of such biases during their development. METHODS We will conduct a search update from an existing scoping review to identify studies on AI and primary care in the following databases: Medline-OVID, Embase, CINAHL, Cochrane Library, Web of Science, Scopus, IEEE Xplore, ACM Digital Library, MathSciNet, AAAI, and arXiv. Two screeners will independently review all abstracts, titles, and full-text articles. The team will extract data using a structured data extraction form and synthesize the results in accordance with PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines. RESULTS This review will provide an assessment of the current state of health care equity within AI for primary care. Specifically, we will identify the degree to which vulnerable patients have been included, assess how bias is interpreted and documented, and understand the extent to which harmful biases are addressed. As of October 2020, the scoping review is in the title- and abstract-screening stage. The results are expected to be submitted for publication in fall 2021. CONCLUSIONS AI applications in primary care are becoming an increasingly common tool in health care delivery and in preventative care efforts for underserved populations. This scoping review would potentially show the extent to which studies on AI in primary care employ a health equity lens and take steps to mitigate bias.

Abstract
This study-using multinomial logistic regressions-analyzed a national sample of 2977 older adults to examine factors associated with their health services utilization in four types of health providers-namely, commune health stations (CHSs), private clinics, private hospitals, and public hospitals in Vietnam. Older Vietnamese favored using public hospitals for their health consultancies, even for regular health checkups. For nonsevere illness, the relative risk ratio of choosing private clinics was three times (95% CI: 2.2-4.1) that of CHSs. Possession of public health insurance was a key enabling factor that influenced the older adults' choice of CHSs over private clinics. Older adults of ethnic minority and living in rural areas were more likely to use CHSs than other health facilities. This study suggests a substantial quality improvement of services at CHSs, an innovative reform toward a diversified structure of private and public clinics to address diverse needs and to strengthen primary care for older adults.

Abstract
AIM This scoping review identifies strengths and weakness of culturally tailored interventions for ethnic minorities' care in the United States. It reviews recently published studies to improve understanding of these interventions for future research and practice. DESIGN Scoping review. METHODS By searching five electronic databases-CINAHL, PubMed, Ovid, Scopus and Web of Science, this review located 58 empirical studies published between 2015-2019. This review was guided by the PRISMA statements. RESULTS The review identified four weaknesses and five strengths of culturally tailored interventions. Weaknesses included unclear guidelines, low attention and retention rates, failure to measure processes and inadequate training for healthcare providers. The intervention strengths were culturally respectful and patient-centred care, healthy lifestyle promotion, increased family and community supports, technology use for efficient and timely care and increased knowledge of disease by participants.

Abstract
BACKGROUND Early in the Covid-19 pandemic, there was uncertainty regarding critical illness prognosis and challenges to traditional face-to-face family meetings. Ethnic minority populations have suffered disproportionately worse outcomes during the pandemic, which may in part relate to differences in end-of-life decision-making. AIM Characterize patterns of and factors associated with decisions to forgo resuscitative efforts, as measured by do-not-resuscitate orders, during critical illness with Covid-19. DESIGN Retrospective cohort with medical record abstraction. SETTING/PARTICIPANTS Adult patients diagnosed with SARS-Cov-2 virus via polymerase chain reaction and admitted to the intensive care unit at an academic hospital, which cares for the city's underserved communities, between March 1 and June 7, 2020 who underwent invasive mechanical ventilation for at least 48 hours. RESULTS In this cohort (n = 155), 45% were black people, and 51% spoke English as their primary language. Median time to first goals-of-care conversation was 3.9 days (IQR 1.9-7.6) after intensive care unit admission. Overall 61/155 patients (39%) transitioned to do-not-resuscitate status, and 50/62 (82%) patients who died had do-not-resuscitate orders. Multivariate analysis shows age and palliative care involvement as the strongest predictors of decision to instate do-not-resuscitate order. There was no association between race, ethnicity, or language and decisions to forego resuscitation. CONCLUSIONS During this time of crisis and uncertainty with limited resources and strained communication, time to first goals of care conversation was shorter than in pre-pandemic studies, but rates of foregoing resuscitation remained similar, with no differences observed by race, ethnicity, or language. This study suggests that early palliative care involvement and non-traditional communications, including videoconferencing, to facilitate goals of care conversations could have mitigated potential disparities in end-of-life decision making patterns during the pandemic.

Abstract
Objective The primary objective of this study was to assess trends in bowel preparation among patients who had elective colectomy between 2012 and 2018. The secondary objective was to assess patient and procedure-related factors predictive of bowel preparation use or lack thereof. Background Numerous studies have demonstrated that bowel preparation before elective colorectal surgery can reduce the risk of postoperative complications. Studies of surgeon practices found 75% to 98% prescribe bowel preparation to their patients, although biases in the study design may lead to overestimation of bowel preparation practice. Methods Cross-sectional study of the National Surgical Quality Improvement Program colectomy procedure targeted dataset. We included patients from 18 to 90 years old who underwent elective colectomy (n = 101,096). The primary outcomes were bowel preparation before elective colectomy, including oral antibiotic only, mechanical only, both oral and mechanical, or none. Results Twenty percent of patients did not do any bowel preparation before elective colectomy. Almost all covariates were independently associated with any bowel preparation, although some were not clinically relevant. The odds that Black/African American or Hispanic patients had any bowel preparation were lower than that of White patients. Additionally, the odds minimally invasive colectomy patients completed any bowel preparation was 1.46 times that of open surgery patients. Conclusions This study is the first of its kind to assess trends in bowel preparation using an objective dataset. Our study highlights disparities in bowel preparation. Further studies should focus on delineating the root cause of this disparity, identifying the barriers, and finding solutions.

Aging (Albany NY) 2021; 13:20029-20049.

Abstract
Introduction: Despite associated with multiple geriatric disorders, whether housing type, an indicator of socioeconomic status (SES) and environmental factors, is associated with accelerated biological aging is unknown. Furthermore, although individuals with low-SES have higher body mass index (BMI) and are more likely to smoke, whether BMI and smoking status moderate the association between SES and biological aging is unclear. We examined these questions in urbanized low-SES older community-dwelling adults. Methods: First, we analyzed complete blood count data using the cox proportional hazards model and derived measures for biological age (BA) and biological age acceleration (BAA, the higher the more accelerated aging) (N = 376). Subsequently, BAA was regressed on housing type, controlling for covariates, including four other SES indicators. Interaction terms between housing type and BMI/smoking status were separately added to examine their moderating effects. Total sample and sex-stratified analyses were performed. Results: There were significant differences between men and women in housing type and BAA. Compared to residents in ≥3 room public or private housing, older adults resided in 1–2 room public housing had a higher BAA. Furthermore, BMI attenuated the association between housing type and BAA. In sex-stratified analyses, the main and interaction effects were only significant in women. In men, smoking status instead aggravated the association between housing type and BAA. Conclusion: Controlling for other SES indicators, housing type is an independent socio-environmental determinant of BA and BAA in a low-SES urbanized population. There were also sex differences in the moderating effects of health behaviors on biological aging.

COVID-19 Deaths in the United States: Shifts in Hot Spots over the Three Phases of the Pandemic and the Spatiotemporally Varying Impact of Pandemic Vulnerability. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:8987. [PMID: 34501577 PMCID: PMC8431027 DOI: 10.3390/ijerph18178987] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 08/20/2021] [Accepted: 08/22/2021] [Indexed: 01/27/2023]
Abstract
The geographic areas most impacted by COVID-19 may not remain static because public health measures/behaviors change dynamically, and the impacts of pandemic vulnerability also may vary geographically and temporally. The nature of the pandemic makes spatiotemporal methods essential to understanding the distribution of COVID-19 deaths and developing interventions. This study examines the spatiotemporal trends in COVID-19 death rates in the United States from March 2020 to May 2021 by performing an emerging hot spot analysis (EHSA). It then investigates the effects of the COVID-19 time-dependent and basic social vulnerability factors on COVID-19 death rates using geographically and temporally weighted regression (GTWR). The EHSA results demonstrate that over the three phases of the pandemic (first wave, second wave, and post-vaccine deployment), hot spots have shifted from densely populated cities and the states with a high percentage of socially vulnerable individuals to the states with relatively relaxed social distancing requirements, and then to the states with low vaccination rates. The GTWR results suggest that local infection and testing rates, social distancing interventions, and other social, environmental, and health risk factors show significant associations with COVID-19 death rates, but these associations vary over time and space. These findings can inform public health planning.

Urinary PGE-M in Men with Prostate Cancer. Cancers (Basel) 2021; 13:cancers13164073.

Abstract
Simple Summary Elevated levels of urinary prostaglandin E metabolite (PGE-M), a marker of inflammation, have previously been associated with cancer incidence and metastasis. Studies investigating PGE-M in prostate cancer are lacking even though chronic inflammation is a candidate risk factor for the disease. We investigated the association of PGE-M with lethal prostate cancer. We measured PGE-M in the urine of men with prostate cancer and in men without prostate cancer (population controls). Our participants included African American and European American men. Because African American men die more frequently from prostate cancer than European American men, we investigated whether high PGE-M may contribute to the increased mortality among African American prostate cancer patients. We did not observe a relationship between PGE-M and prostate cancer aggressiveness or prostate cancer-specific mortality in our study population, neither in the combined cohort nor in the race/ethnicity stratified analysis. Interestingly, however, we observed a significant relationship between high PGE-M and all-cause mortality in African American men with prostate cancer. Yet, there was no association between high PGE-M and all-cause mortality when these men were regular aspirin users. Abstract Urinary PGE-M is a stable metabolite of prostaglandin E2 (PGE2). PGE2 is a product of the inflammatory COX signaling pathway and has been associated with cancer incidence and metastasis. Its synthesis can be inhibited by aspirin. We investigated the association of PGE-M with lethal prostate cancer in a case–control study of African American (AA) and European American men. We measured urinary PGE-M using mass-spectrometry. Samples were obtained from 977 cases and 1022 controls at the time of recruitment. We applied multivariable logistic and Cox regression modeling to examine associations of PGE-M with prostate cancer and participant survival. Median survival follow-up was 8.4 years, with 246 deaths among cases. Self-reported aspirin use over the past 5 years was assessed with a questionnaire. Race/ethnicity was self-reported. Urinary PGE-M levels did not differ between men with prostate cancer and population-based controls. We observed no association between PGE-M and aggressive disease nor prostate-cancer-specific survival. However, we observed a statistically significant association between higher (>median) PGE-M and all-cause mortality in AA cases who did not regularly use aspirin (HR = 2.04, 95% CI 1.23–3.37). Among cases who reported using aspirin, there was no association. Our study does not support a meaningful association between urinary PGE-M and prostate cancer. Moreover, PGE-M levels were not associated with aggressive prostate cancer. However, the observed association between elevated PGE-M and all-cause mortality in AA non-aspirin users reinforces the potential benefit of aspirin to reduce mortality among AA men with prostate cancer.

Abstract
Aim: To assess the perception of telehealth visits among a multiracial cancer population during the coronavirus disease 2019 pandemic. Methods: This cross-sectional study was conducted at outpatient cancer clinics in Hawaii between March and August 2020. Patients were invited to participate in the survey either by phone or email. Results: Of the 212 survey respondents, 61.3% were Asian, 23.6% were White and 15.1% were Native Hawaiians or Pacific Islanders. Asians, Native Hawaiians and Pacific Islanders were less likely to desire future telehealth visits compared with Whites. Predictors with regard to preferring future telehealth visits included lower income and hematopoietic cancers. Conclusion: The authors found racial differences in preference for telehealth. Future studies aimed at overcoming these racial disparities are needed to provide equitable oncology care.

Abstract
Suicide remains the leading cause of death among homeless youth. We assessed differences in health-care utilization between homeless and nonhomeless youth presenting to the emergency department or hospital after a suicide attempt. New York Statewide Inpatient and Emergency Department Databases (2009-2014) were used to identify homeless and nonhomeless youth aged 10-17 who utilized health-care services following a suicide attempt. To evaluate associations with homelessness, we used logistic regression models for use of violent means, intensive care unit utilization, log-transformed linear regression models for hospitalization cost, and negative binomial regression models for length of stay. All models adjusted for individual characteristics with a hospital random effect and year fixed effect. We identified 18,026 suicide attempts with health-care utilization rates of 347.2 (95% confidence interval (CI): 317.5, 377.0) and 67.3 (95% CI: 66.3, 68.3) per 100,000 person-years for homeless and nonhomeless youth, respectively. Length of stay for homeless youth was statistically longer than that for nonhomeless youth (incidence rate ratio = 1.53, 95% CI: 1.32, 1.77). All homeless youth who visited the emergency department after a suicide attempt were subsequently hospitalized. This could suggest a higher acuity upon presentation among homeless youth compared with nonhomeless youth. Interventions tailored to homeless youth should be developed.

Abstract
BACKGROUND Thromboxane A2 (TXA2) is a platelet- and cyclooxygenase-derived eicosanoid that has been linked to metastasis. We investigated the role of TXA2 in the development of lethal prostate cancer in African American (AA) and European American (EA) men. METHODS We measured urinary 11-dehydrothromboxane B2 (TXB2), a stable metabolite of TXA2, with mass-spectrometry. Samples were obtained from 977 cases and 1022 controls at time of recruitment. We applied multivariable logistic and Cox regression modeling to examine associations of TXB2 with prostate cancer and patient survival. Median survival follow-up was 8.4 years with 246 deaths among cases. Aspirin use was assessed with a questionnaire. Race/ethnicity was self-reported. RESULTS Urinary TXB2 was inversely associated with aspirin use. High (> median) TXB2 was associated with prostate cancer in AA (adjusted odds ratio [OR] = 1.50, 95% confidence interval [CI]= 1.13-2.00) but not EA men (OR = 1.07, 95% CI = 0.82-1.40), suggesting upregulated TXA2 synthesis in AA men with prostate cancer. High TXB2 was positively associated with metastatic prostate cancer (OR = 2.60, 95%CI = 1.08-6.28), compared with low (≤ median) TXB2. Furthermore, high TXB2 was also associated with all-cause (adjusted hazard ratio = 1.59, 95% CI = 1.06-2.40) and prostate cancer-specific mortality (hazard ratio = 4.74, 95%CI = 1.62-13.88 in AA men only. CONCLUSION We report a distinct association of TXB2 with prostate cancer outcomes in AA men. In this high-risk group of men, upregulation of TXA2/TXB2 synthesis may promote metastasis and lethal disease. Our observation identifies a potential benefit of aspirin in preventing lethal prostate cancer through inhibition of TXA2 synthesis.

Abstract
BACKGROUND To understand the clinical, bacterial, and host characteristics associated with recurrent Staphylococcus aureus bacteremia (R-SAB), patients with R-SAB were compared to contemporaneous patients with a single episode of SAB (S-SAB). METHODS All SAB isolates underwent spa genotyping. All isolates from R-SAB patients underwent pulsed-field gel electrophoresis (PFGE). PFGE-indistinguishable pairs from 40 patients underwent whole genome sequencing (WGS). Acute phase plasma from R-SAB and S-SAB patients was matched 1:1 for age, race, sex, and bacterial genotype, and underwent cytokine quantification using 25-analyte multiplex bead array. RESULTS R-SAB occurred in 69 (9.1%) of the 756 study patients. Of the 69 patients, 30 experienced relapse (43.5%) and 39 reinfection (56.5%). Age, race, hemodialysis dependence, presence of foreign body, methicillin-resistant Staphyloccus aureus, and persistent bacteremia were individually associated with likelihood of recurrence. Multivariate risk modeling revealed that black hemodialysis patients were nearly 2 times more likely (odds ratio [OR] = 9.652 [95% confidence interval [CI], 5.402-17.418]) than white hemodialysis patients (OR = 4.53 [95% CI, 1.696-10.879]) to experience R-SAB. WGS confirmed PFGE interpretations in all cases. Median RANTES (regulated on activation, normal T cell expressed and secreted) levels in acute phase plasma from the initial episode of SAB were higher in R-SAB than in matched S-SAB controls (P = .0053, false discovery rate < 0.10). CONCLUSION This study identified several risk factors for R-SAB. The largest risk for R-SAB is among black hemodialysis patients. Higher RANTES levels in R-SAB compared to matched controls warrants further study.

Abstract
PURPOSE We investigate whether exposure to violence (ETV) during adolescence and emerging adulthood predicts engagement in chronic disease-related health risk behaviors years later among African Americans. DESIGN A longitudinal study following youth from mid-adolescence (mean age = 14.8 years) to young adulthood (mean age = 32.0 years). SETTING Flint, Michigan. SAMPLE Four hundred forty-two African American (96.2%) and mixed African American and White (3.8%) participants. MEASURES Outcomes were diet, smoking, drinking, and physical inactivity. Covariates were ETV, sex, mother's educational attainment, and substance use by siblings, peers, and parents. ANALYSIS Latent profile analysis was conducted to identify distinct patterns of adult health risk behaviors and assess the association of youth ETV and identified patterns. RESULTS Four latent profiles were identified: high substance use (n = 46; 10.41%), high overall risk (n = 71; 16.06%), low overall risk (n = 140; 31.67%) and inactive (n = 185, 41.86%). Relative to the low overall risk profile, ETV was associated with being in the high overall risk profile (b = 0.37, p = 0.04), but not other profiles. Female gender and higher maternal education were associated with being in the inactive profile compared to the low overall risk profile. Peer alcohol and tobacco use were associated with being in the high substance use profile. CONCLUSION ETV during adolescence and emerging adulthood increased the risk of engagement in multiple health risk behaviors later in life.

Abstract
Health equity can be defined as the absence of systematic disparities in health between more and less advantaged social groups. Gout is one of the most common forms of arthritis and disproportionally affects Indigenous peoples, including Māori in Aotearoa New Zealand. Inequities in gout management are well documented and clearly evidenced in Indigenous populations. For example, while gout occurs at a younger age and is more severe in Māori, there is less regular dispensing of urate-lowering therapies. Indigenous peoples are also under-represented in clinical trials. Herein, we will review inequities in gout using Aoteoaroa New Zealand as an example. We will explore reasons for health inequities and challenges that need to be faced to achieve health equity.

Abstract
Introduction Ovarian cancer is the fifth-leading cause of cancer-related mortality in US women. There are survival disparities between non-Hispanic black (NHB) and non-Hispanic white (NHW) women. We assessed if insurance status or extent of disease modified the effect of race/ethnicity on survival for ovarian cancer. Methods A historical cohort was assembled using the 2007-2015 National Cancer Institute’s Surveillance, Epidemiology, and End Result (SEER) dataset. Adult NHB and NHW (>18 years) diagnosed with regional and distant ovarian cancer were included. The outcome was five-year cause-specific mortality. Multivariable Cox regression models were fitted, including race by the extent of disease and race by insurance status interaction terms. Results For each significant interaction, separate Cox models were fitted. In total 8,043 women were included. The insurance status/race interaction was not statistically significant, but the extent of disease modified the effect of race on survival. NHB survival was lower in regional disease (adjusted hazard ratio (HR) =1.6; 95% confidence interval (CI) 1.1-2.4), while there was no difference in survival between women with distant disease (adjusted HR =1.0; 95%CI 0.9-1.2). Conclusions Ovarian cancer mortality is similar between NHB and NHW women with the distant disease but higher in NHB women with regional disease. Further research should clarify whether this difference is due to access to quality cancer treatment or other factors affecting treatment response.

Abstract
ARIC (Atherosclerosis Risk In Communities) initiated community-based surveillance in 1987 for myocardial infarction and coronary heart disease (CHD) incidence and mortality and created a prospective cohort of 15,792 Black and White adults ages 45 to 64 years. The primary aims were to improve understanding of the decline in CHD mortality and identify determinants of subclinical atherosclerosis and CHD in Black and White middle-age adults. ARIC has examined areas including health disparities, genomics, heart failure, and prevention, producing more than 2,300 publications. Results have had strong clinical impact and demonstrate the importance of population-based research in the spectrum of biomedical research to improve health.

Abstract
Weighing the dilemma of reopening schools during the pandemic is no longer a matter of self-determination but harm. Coronavirus disease 2019 has shown gross health inequality and, by extension, the inequality of society per se. The assertion that ‘education continues despite the pandemic’ using access to technological means is a privileged position.

Abstract
Despite substantial improvements in cancer survival, not all population groups have benefitted equally from this progress. For prostate cancer, men of African descent in the United States and England continue to have about double the rate of fatal disease compared to other men. Studies suggest that when there is equal access to care, survival disparities are greatly diminished. However, notable differences exist in prostate tumor biology across population groups. Ancestral factors and disparate exposures can lead to altered tumor biology, resulting in a distinct disease etiology by population group. While equal care remains the key target to improve survival, additional efforts should be made to gain comprehensive knowledge of the tumor biology in prostate cancer patients of African descent. Such an approach may identify novel intervention strategies in the era of precision medicine. A growing body of evidence shows that inflammation and the immune response may play a distinct role in prostate cancer disparities. Low-grade chronic inflammation and an inflammatory tumor microenvironment are more prevalent in African American patients and have been associated with adverse outcomes. Thus, differences in activation of immune-inflammatory pathways between African American and European American men with prostate cancer may exist. These differences may influence the response to immune therapy which is consistent with recent observations. This review will discuss mechanisms by which inflammation may contribute to the disparate outcomes experienced by African American men with prostate cancer and how these immunogenic and inflammatory vulnerabilities could be exploited to improve their survival.

Abstract
Job loss and evictions tied to the COVID-19 pandemic are expected to significantly increase homelessness in the coming months. Reciprocally, homelessness and the many vulnerabilities that inevitably accompany it are driving COVID-19 outbreaks in U.S. shelters and other congregate living situations. Unless we intervene to address homelessness, these co-existing and synergistic situations will make the current public health crisis even worse. Preventing homelessness and providing permanent affordable housing has reduced the ravages of the HIV epidemic. We must take the lessons learned in 40 years of fighting HIV to respond effectively to the COVID-19 crisis. Housing is an investment that will curb the spread of COVID-19 and help protect all of us from future pandemics.

Abstract
Background: Black mothers in the United States have shorter breastfeeding (BF) durations and less exclusive breastfeeding (EBF) than others. The factors underlying these disparities require investigation. Methods: Using longitudinal data from a CDC-sponsored birth cohort in Cincinnati, Ohio, we analyzed the factors mediating racial disparity in BF outcomes. Study mothers were enrolled in prenatal clinics associated with two large birth hospitals. Analysis was restricted to racial groups with sufficient numbers in the cohort, non-Hispanic Black (n = 92) and White (n = 113) mothers, followed to at least 6 months postpartum. Results: Black mothers were 25 times more likely to reside in socioeconomically deprived neighborhoods and 20 times more likely to have an annual household income <$50,000/year than White mothers (p < 0.001). The gap in EBF for 6 weeks was 45 percentage points by racial group (13%-Black mothers versus 58%-White mothers, p < 0.001); in any BF at 6 months was 37 percentage points (28%-Black mothers versus 65%-White mothers, p < 0.001); and in mothers meeting their own intention to BF at least 6 months was 51 percentage points (29%-Black mothers versus 80%-White mothers, p < 0.001). Racial disparity in EBF at 6 weeks was mediated in logistic regression models by inequities in socioeconomic position, maternal hypertension, and BF intention. Racial disparities in BF at 6 months or meeting 6-month BF intention were mediated by inequities in socioeconomic position, maternal obesity, and EBF at 6 weeks. Not all BF disparities could be explained by models used in these analyses. Conclusions: Efforts to lessen BF disparities should address the underlying structural inequities that disproportionately affect Black mothers and children, should incorporate maternal health, and focus on breastfeeding exclusivity and duration. Few Black mothers achieved EBF at 6 weeks, which contributed to disparity in BF duration. Greater attention to Black mother-infant pairs is a public health priority.

Abstract
Comorbid chronic diseases affect cancer patients with an increasing frequency as populations get older. They negatively and disproportionately impact underserved populations and influence cancer diagnosis, tumor biology and metastasis, and choice of treatment. Many comorbidities are associated with a delayed cancer diagnosis. Although the relationship between comorbidities and cancer risk and survivorship has been studied extensively, we still lack knowledge on how they affect tumor biology and the metastatic process. Here, we will discuss our current understanding of mechanisms linking comorbidities to an adverse tumor biology and lethality and introduce thoughts of how we can close existing gaps in this knowledge. We argue that research into comorbidity-induced alterations in cancer metastasis, immunity, and metabolism should be prioritized.
