Exploring cancer health disparities among formerly incarcerated African Americans

Incarcerated populations have a higher burden of chronic disease and elevated risk factors for cancer (BJS, 2012). In 2013, cancer (31%) and heart disease (26%) accounted for over half of all prisoner deaths. The Genomics Research Program of the National Cancer Institute’s Division of Cancer Control and Population Sciences (2016) identified incarcerated persons as an understudied population about which there is limited data regarding cancer risks and outcomes. A majority of studies on corrections populations focus on health issues associated with reduction of infectious diseases such as HIV, Tuberculosis, and Hepatitis. Scant research has been conducted on issues associated with cancer prevention and control among African Americans with a history of incarceration. This qualitative, participatory, pilot research study explores the domains of cancer health disparities among African American men and women who were formerly incarcerated in Illinois prisons. Four qualitative focus groups will be conducted. The primary purpose of the focus groups is to collect and qualitatively analyze preliminary data on the barriers to access, utilization and treatment of cancer. This presentation seeks to: (1) describe the need for enhanced access to cancer care and treatment, (2) advocate for the inclusion of best practices in cancer care in corrections systems and, (3) identify policy recommendations and initiatives aimed at reducing cancer disparities among incarcerated and formerly incarcerated persons

Implications of the Plastid Genome Sequence of Typha (Typhaceae, Poales) for Understanding Genome Evolution in Poaceae

Plastid genomes of the grasses (Poaceae) are unusual in their organization and rates of sequence evolution. There has been a recent surge in the availability of grass plastid genome sequences, but a comprehensive comparative analysis of genome evolution has not been performed that includes any related families in the Poales. We report on the plastid genome of Typha latifolia, the first non-grass Poales sequenced to date, and we present comparisons of genome organization and sequence evolution within Poales. Our results confirm that grass plastid genomes exhibit acceleration in both genomic rearrangements and nucleotide substitutions. Poaceae have multiple structural rearrangements, including three inversions, three genes losses (accD, ycf1, ycf2), intron losses in two genes (clpP, rpoC1), and expansion of the inverted repeat (IR) into both large and small single-copy regions. These rearrangements are restricted to the Poaceae, and IR expansion into the small single-copy region correlates with the phylogeny of the family. Comparisons of 73 protein-coding genes for 47 angiosperms including nine Poaceae genera confirm that the branch leading to Poaceae has significantly accelerated rates of change relative to other monocots and angiosperms. Furthermore, rates of sequence evolution within grasses are lower, indicating a deceleration during diversification of the family. Overall there is a strong correlation between accelerated rates of genomic rearrangements and nucleotide substitutions in Poaceae, a phenomenon that has been noted recently throughout angiosperms. The cause of the correlation is unknown, but faulty DNA repair has been suggested in other systems including bacterial and animal mitochondrial genomes

Inside to Outside: A Collaborative Effort to Address Cancer Disparities among Incarcerated and Formerly Incarcerated Populations

Inmates experience higher rates of serious and chronic illness. Among the chronic illnesses experienced by this population is the diagnosis of cancer. During the past decade the incidence of cancer has slowly but steadily increased. One explanation for this increase in cancer diagnosis in correctional populations is the aging of the population. However, cancer diagnosis is not only evident in the aging inmate population (65 or older) but there is evidence of a younger population (30-45) presenting with cancer at intake or receiving a cancer diagnosis within months of admission to our jails and prisons. The consistent increase in patients with or diagnosis with cancer suggest a need to explore strategies to successfully manage and provide care meeting best practice standards for this special population. The increase in patients with a diagnosis of cancer further suggests a need to develop policies that decrease the risk of cancer disparities in the inmate population and among formerly incarcerated persons. Ensuring access to quality of care and continuity of care for patients with cancer requires health professionals to be vigilant in screening, health promotion, prevention and treatment. Presenters will discuss approaches to care and treatment and policy implications for this population

Nurse academic partnerships in justice systems: Building upon the evidence.

Students in corrections are vital to meet the needs of this population, decrease stigmatization and increase compassion.•Clinical experience in correctional settings can provide a meaningful learning experience for nursing students at all levels.•Research partnerships between corrections and academia can contribute to enhancing the care provided in correctional systems.•Correctional health offers opportunities for faculty to grow clinical, research, leadership and advocacy skills

A Type VI secretion system encoding locus is required for Bordetella bronchiseptica immunomodulation and persistence in vivo.

Type VI Secretion Systems (T6SSs) have been identified in numerous gram-negative pathogens, but the lack of a natural host infection model has limited analysis of T6SS contributions to infection and pathogenesis. Here, we describe disruption of a gene within locus encoding a putative T6SS in Bordetella bronchiseptica strain RB50, a respiratory pathogen that circulates in a broad range of mammals, including humans, domestic animals, and mice. The 26 gene locus encoding the B. bronchiseptica T6SS contains apparent orthologs to all known core genes and possesses thirteen novel genes. By generating an in frame deletion of clpV, which encodes a putative ATPase required for some T6SS-dependent protein secretion, we observe that ClpV contributes to in vitro macrophage cytotoxicity while inducing several eukaryotic proteins associated with apoptosis. Additionally, ClpV is required for induction of IL-1β, IL-6, IL-17, and IL-10 production in J774 macrophages infected with RB50. During infections in wild type mice, we determined that ClpV contributes to altered cytokine production, increased pathology, delayed lower respiratory tract clearance, and long term nasal cavity persistence. Together, these results reveal a natural host infection system in which to interrogate T6SS contributions to immunomodulation and pathogenesis

The association of resistin with cardiovascular disease in the Multi-Ethnic Study of Atherosclerosis

ObjectiveTo describe the relationship between circulating resistin levels and cardiovascular diseases (CVD) and all-cause death in a multi-ethnic cohort.Methods and resultsWe studied 1913 participants from the Multi-Ethnic Study of Atherosclerosis with measurements of plasma resistin levels. Absolute proportions experiencing new-onset atrial fibrillation (AF), atherosclerotic CVD (myocardial infarction, angina, resuscitated cardiac arrest, stroke), heart failure (HF), and all-cause death were calculated for each quartile of resistin. We used adjusted Cox proportional regression modeling resistin as a continuous variable per standard deviation of log-transformed resistin and secondarily as a categorical variable using resistin quartiles. Results were stratified by sex and race/ethnicity. The mean age of the population was 64.5 ± 10 years with half being female and a median resistin concentration of 15.1 ng/mL (11.9-19.1). Mean follow-up time was 7.2 ± 1.8 years. There was a graded increase in the occurrence of all outcomes across increasing quartiles of resistin. Modeled as a continuous variable, after adjustment for anthropomorphic measures, traditional risk factors, markers of inflammation, and other adipokines, significant associations were noted for HF (HR 1.4, CI 1.0-2.0), hard and all CVD (HR 1.3, 1.1-1.7 and 1.3, 1.1-1.6, respectively), and CHD (HR 1.31, 1.0-1.6), but not for AF or death. Significant interaction terms were noted between resistin and race, with Hispanic race/ethnicity showing the strongest relationship between resistin and outcomes.ConclusionsIn an ethnically diverse population without known CVD at baseline, there was a strong, independent association between higher resistin levels and incident CVD, CHD and HF

Multistate analysis of prospective Legionnaires' disease cluster detection using SaTScan, 2011-2015.

Detection of clusters of Legionnaires' disease, a leading waterborne cause of pneumonia, is challenging. Clusters vary in size and scope, are associated with a diverse range of aerosol-producing devices, including exposures such as whirlpool spas and hotel water systems typically associated with travel, and can occur without an easily identified exposure source. Recently, jurisdictions have begun to use SaTScan spatio-temporal analysis software prospectively as part of routine cluster surveillance. We used data collected by the Active Bacterial Core surveillance platform to assess the ability of SaTScan to detect Legionnaires' disease clusters. We found that SaTScan analysis using traditional surveillance data and geocoded residential addresses was unable to detect many common Legionnaires' disease cluster types, such as those associated with travel or a prolonged time between cases. Additionally, signals from an analysis designed to simulate a real-time search for clusters did not align with clusters identified by traditional surveillance methods or a retrospective SaTScan analysis. A geospatial analysis platform better tailored to the unique characteristics of Legionnaires' disease epidemiology would improve cluster detection and decrease time to public health action
