This paper presents the results of the literature review conducted for the working group topic on inflammation, infection, exposure, and the human microbiome. Infection and chronic inflammation can elevate risk for cardiovascular disease and cancer. Environmental exposures common among South Asian (SA) subgroups, such as arsenic exposure among Bangladeshis and particulate matter air pollution among taxi drivers, also pose risks. This review explores the effects of exposure to arsenic and particulate matter, as well as other infections common among SAs, including human papillomavirus (HPV) and hepatitis B/C infection. Emerging research on the human microbiome, and the effect of microbiome changes on obesity and diabetes risk among SAs are also explored.

PURPOSE/UNASSIGNED:Housing status can become compromised in the wake of financial hardship for some patients with cancer and become a source of disparity. This qualitative study describes the types of housing issues experienced by patients with cancer and survivors of cancer in New York City. METHODS/UNASSIGNED:Semistructured interviews were conducted with a volunteer sample of 21 patients with cancer or survivors of cancer treated in New York City who reported housing needs in the period after diagnosis through survivorship. Nine supplemental interviews were conducted with cancer and housing key informants. Conventional content analysis was conducted on transcripts to create a codebook describing types of housing needs. RESULTS/UNASSIGNED:Patients and survivors most commonly had breast (n = 9) and blood (n = 4) cancers and ranged from recently diagnosed to many years posttreatment. Twenty-nine distinct housing-related issues were identified, which were grouped into the following six major categories: housing costs (eg, rent, mortgage), home loss, doubled up or unstable housing, housing conditions, accessibility (eg, stairs, proximity to amenities), and safety. Issues were often interrelated. Housing needs sometimes predated cancer diagnosis. Other issues newly emerged in the wake of cancer-related physical limitations and disruption to finances. Needs ranged in severity and caused patients and survivors considerable burden during a difficult period of poor health and financial strain. CONCLUSION/UNASSIGNED:This study contributes depth to current understandings of housing needs among patients with cancer and survivors by providing detailed disaggregated descriptions. We recommend increasing availability of services responsive to these needs and exploring promising options such as patient navigation and legal services. Findings also highlight the importance of creative solutions addressing ecologic-level factors such as housing affordability.

BACKGROUND:Language barriers can influence the quality of health care and health outcomes of limited English proficient patients with cancer. The use of medical interpretation services can be a valuable asset for improving communications in emergency care settings. OBJECTIVE:To evaluate whether a mobile translation application increased call frequency to interpreter services among providers in an Urgent Care Center at a comprehensive cancer center and to assess provider satisfaction of the mobile application. RESEARCH DESIGN/METHODS:Prospective pre-post nonrandomized intervention of a mobile translation application with access to an over the phone interpreter (OPI) service at the push of a button and poststudy satisfaction survey. SUBJECTS/METHODS:Sixty-five clinicians working at the Urgent Care Center in a cancer center in New York City. MEASURES/METHODS:Mean call frequency to OPI services, tested by the nonparametric Wilcoxon Mann Whitney test, and self-reported provider satisfaction descriptives. RESULTS:The mobile application contributed to increasing the frequency of phone calls to OPI services during the intervention period (mean=12.8; P=0.001) as compared with the preintervention period (mean=4.3), and showed continued use during the postintervention period (mean=5.7). Most clinicians were satisfied with the use of the mobile application and access to the OPI services. CONCLUSIONS:The results suggest that mobile application tools contribute to increasing the use and ease of access to language services. This has the potential to improve the quality of communication between medical providers and limited English proficient patients in the delivery of cancer care in urgent care settings.

Following a 1983 chromic acid (hexavalent chromium [CrVI]) spill from a Garfield, NJ electroplating plant, CrVI-contaminated water was found in a local firehouse basement in 1993. An ATSDR public health advisory was issued for the plant site in 2010, and from 2008-2015, fourteen residential properties have required remediation to address CrVI-contaminated dust in the basements. As part of the Community Outreach and Engagement Core of the NYU NIEHS Center, seventytwo Garfield residents aged 18-65 years, participated in a community survey with the goal of identifying concerns related to environmental and community health. Thirty-two percent responded that they 'didn't know' if they were exposed to chemicals or pollutants where they live. This finding suggests a limited awareness of environmental chemical exposures, chromium contamination and/or potential exposure to CrVI. Furthermore, toenail clippings were collected from forty-seven Garfield residents and analyzed for total chromium levels to assess potential long-term exposure. On average, residents living on/inside the contaminated plume area had higher total chromium levels in their toenail clippings than residents living outside the plume area. However, chromium levels for all participants were within the range of historical normal. This study highlights the value of partnerships between environmentally-impacted community's and academic scientists working together to identify potential contaminant exposures and address public health concerns through research and environmental health education.

The incidence of hepatocellular carcinoma (HCC) is rising sharply in the United States and deaths from HCC have increased at the highest rate of all cancers. Though Asians have the highest incidence of HCC of all ethnicities in the US, racial/ethnic minorities, including Asians, have worse survival from HCC. We sought to identify barriers to care in treatment of HCC among affected individuals in the NYC Chinese immigrant community. We held focus groups with Chinese immigrant patients in NYC with HCC. 29 individuals participated in the focus groups. We analyzed focus group data using grounded theory methodology. Barriers to care identified included insurance, money, time, language, residency status, and stigma. The impact of provider bias and culture were also discussed. Knowledge gathering with minority patients with HCC is essential for us to fully comprehend the barriers to healthcare experienced by this community. Future policy and intervention efforts must be founded in this reality.

OBJECTIVE:In the United States, hepatocellular carcinoma (HCC) is more common among communities with low socioeconomic status (SES), and these groups tend to be diagnosed with later-stage cancers. Sorafenib is the primary treatment for advanced HCC, however its substantial cost raises concern for access to treatment. METHODS:The newly developed Case-Background method was used to estimate odds ratios for the impacts of various sociodemographic factors on sorafenib access in clinically eligible patients. Socioeconomic status was defined as a factor of median income and education level based on ZIP code of residence. RESULTS:There was a strong association between sorafenib prescription and residence in an area of higher SES. While controlling for age, race/ethnicity, and insurance status, high SES residence doubled the odds of sorafenib prescription (OR=2.05, p<.01). CONCLUSIONS:Low socioeconomic status communities appear to have a reduced chance of receiving the only effective treatment for advanced HCC.

Exposure to fine particulate matter (PM2.5) and black carbon (BC) have been linked to negative health risks, but exposure among professional taxi drivers is understudied. This pilot study measured drivers' knowledge, attitudes, and beliefs (KAB) about air pollution compared with direct measures of exposures. Roadside and in-vehicle levels of PM2.5 and BC were continuously measured over a single shift on each subject, and exposures compared with central site monitoring. One hundred drivers completed an air pollution KAB questionnaire, and seven taxicabs participated in preliminary in-cab air sampling. Taxicab PM2.5 and BC concentrations were elevated compared with nearby central monitoring. Average PM2.5 concentrations per 15-min interval were 4-49 mug/m3. BC levels were also elevated; reaching>10 mug/m3. Fifty-six of the 100 drivers surveyed believed they were more exposed than non-drivers; 81 believed air pollution causes health problems. Air pollution exposures recorded suggest that driver exposures would likely exceed EPA recommendations if experienced for 24 h. Surveys indicated that driver awareness of this was limited. Future studies should focus on reducing exposures and increasing awareness among taxi drivers.Journal of Exposure Science and Environmental Epidemiology advance online publication, 11 May 2016; doi:10.1038/jes.2016.23.

Breast cancer affects one in eight women across the United States, and low-income minority survivors of breast cancer are at increased risk of job loss, compared to higher-income white survivors. Employer accommodations, such as schedule flexibility, have been associated with job retention in higher-income whites, but the role of such accommodations in job retention among low-income minorities is not well understood. We conducted a longitudinal study of 267 employed women ages 18-64 who were undergoing treatment for early-stage breast cancer and spoke English, Chinese, Korean, or Spanish. We categorized patients by income level and by race/ethnicity. The category with the lowest job retention after treatment was low-income women (57 percent). Job retention varied widely by race/ethnicity, ranging from 68 percent among Chinese women to 98 percent among non-Latina whites. Women who had accommodating employers were more than twice as likely to retain their jobs as those without accommodating employers. Low-income women were less likely than higher-income women to have accommodating employers, however. More uniform implementation of accommodations across low- and high-paying jobs could reduce disparities in employment outcomes among workers with a cancer diagnosis. Additional research is needed to better understand the barriers that employers, particularly those with low-income workers, may face in providing accommodations.
