Prevalence and Determinants of Unmet Social Needs Among Rural and Urban Veterans.

Purpose: To examine the prevalence and determinants of nine unmet social needs among rural compared with urban Veterans.

Methods: Retrospective study using survey data collected in 2020 merged with Veterans Health Administration (VA) administrative data. For each unmet need, separate logistic regression modes were run predicting the odds of rural compared with urban Veterans endorsing the need adjusting for sociodemographic characteristics and comorbidities.

Relationship Between Unmet Social Needs and Care Access in a Veteran Cohort.

Background: The association between unmet social needs (e.g., food insecurity) and adverse health outcomes is well-established, especially for patients with and at risk for cardiovascular disease (CVD).

Genomic diversity and evolution of papillomaviruses in rhesus monkeys.

We are studying the diversity of and relationships among papillomaviruses (PVs) to understand the modes and timescales of PV evolution and in the hope of finding animal PVs that may serve as model systems for disease caused by human PVs (HPVs). Toward this goal, we have examined 326 genital samples from rhesus monkeys and long-tailed macaques with a PCR protocol optimized for detecting genital HPV types. In 28 of the rhesus monkey samples, we found amplicons derived from 12 different and novel PV genomes, RhPV-a to RhPV-m, with the likely taxonomic status of "type.

Genital papillomaviruses (PVs) and epidermodysplasia verruciformis PVs occur in the same monkey species: implications for PV evolution.

Portions of the genome from two different papillomaviruses (PVs) of the Abyssinian Colobus monkey were sequenced and phylogenetically analyzed. This revealed that the major evolutionary separation between genital PVs and epidermodysplasia verruciformis-associated PVs (EV-PVs) hitherto found only in human papillomaviruses (HPVs) also exists in animal PVs. The sequence of the long control region (LCR) of Colobus monkey PV type 2 (CgPV-2) reveals a small size and an arrangement of potential cis-responsive elements typical of the EV-HPVs; namely four binding sites for the viral E2 protein, with one of them being located within the L1 gene, a cluster of nuclear factor I (NFI)- and AP-1-binding sites and a 50-bp sequence upstream of the E6 gene consisting only of the nucleotides A and T.

The E5 gene product of rhesus papillomavirus is an activator of endogenous Ras and phosphatidylinositol-3'-kinase in NIH 3T3 cells.

We examined the effect of two rhesus papillomavirus 1 (RhPV) oncogenes on cytokine-induced signal transduction pathways leading to the possible activation of Ras protein (p21ras) and phosphatidylinositol kinase. p21ras in both the activated (GTP-bound) and inactivated (GDP-bound) states were quantitated. NIH 3T3 cell lines expressing the RhPV 1 E5 gene or epidermal growth factor receptor cDNA had about a sixfold higher ratio of p21ras-bound GTP to p21ras-bound GDP as compared with parental NIH 3T3 cells or a cell line expressing the RhPV 1 E7 gene under normal culture conditions, yet expressed similar levels of p21ras.
