How Can I Help You?Eligibility Worker: Navigating Patients Through the Social Services Maze

Introduction: Vermont has programs to assist low income individuals in obtaining basic needs such as health insurance, food security, fuel assistance, housing and transportation. However, these services are often underutilized by eligible individuals. Major barriers to enrollment include lack of knowledge about available programs and their income cutoffs, cumbersome application processes, literacy barriers, and lack of transportation to application sites. In other states, efforts to reduce these barriers have included shortened application forms, removal of asset tests, mail-in applications, media outreach, and eligibility workers placed in outreach agencies. Many studies suggest that the presence of an eligibility worker at a community health center can help overcome some social service enrollment barriers.https://scholarworks.uvm.edu/comphp_gallery/1012/thumbnail.jp

Removing Barriers to Health Care: Healthy Starts for New Americans

Objectives: • To determine if refugees completing a Medical Orientation Program for New Americans are better with several aspects of medicine in the US, such as making appointments; knowing more about diet and hygiene; and understanding the implications of mental and chronic illnesses. • To determine if Medical Passports provided to these individuals to improve continuity of care are useful and effective. • To make recommendations for improvements to the Medical Orientation Program for New Americans to the Community Health Center of Burlington (CHCB).https://scholarworks.uvm.edu/comphp_gallery/1052/thumbnail.jp

Identifying barriers to care in the Burmese and Bhutanese refugee populations of Burlington, Vermont

Introduction: Many refugees who escape persecution in their own country have trouble navigating and accessing the American health care system. Language barriers often impair effective communication, while financial challenges can be prohibitive after the eight-month government insurance subsidy for new refugees expires. In addition many refugees do not understand the concept of chronic disease, which is a concern considering the overall rise in hypertension (HTN) and type-two diabetes mellitus (T2DM) in the US population. Understanding how refugees access health care, and how well they understand chronic disease, is essential for organizations providing medical care for these populations. Little is known about how the Burmese and Bhutanese refugees experience the Vermont health care system, nor how well they understand chronic diseases such as HTN and T2DM. To address these limitations, we conducted focus groups with these two Vermont refugee populations at the Community Health Center of Burlington, Vermont (CHCB).https://scholarworks.uvm.edu/comphp_gallery/1035/thumbnail.jp

Health Coverage History of Local Uninsured PatientsAssessing the Need for an Eligibility Specialist

Abstract: Uninsured Americans are a growing population as insurance premiums climb and fewer employers offer health coverage. Providing medical care to the uninsured often represents a significant financial loss to medical institutions. Our study sought to describe the insurance history and barriers to obtaining health coverage for uninsured patients at the Community Health Center of Burlington, Vermont (CHCB). The potential benefit of adding an insurance eligibility position to the staff at CHCB was also explored. Data were collected by random phone survey from 100 CHCB patients identified as uninsured at their last visit; patients were queried regarding insurance history and interest in enrollment assistance. At the time of survey 66% were currently uninsured, and the majority (87.9%) of these respondents previously held insurance. Loss of insurance was most often due to a change in job status, income or a change in eligibility. Cost was a major barrier to insurance noted by individuals; on average respondents indicated they would be willing to pay around $65 per month for overage. A majority (75.7%) of uninsured respondents also expressed interest in an onsite eligibility worker. These data suggest that the patient population at CHCB would be well served by implementing some form of eligibility staffing. There are a number of different health insurance options in Vermont that could benefit these patients, provided they have assistance with applying. Due to the small sample size of our survey, we recommend that the scope of the eligibility position be determined by closely examining the caseload encountered.https://scholarworks.uvm.edu/comphp_gallery/1025/thumbnail.jp

The SWI/SNF complex acts to constrain distribution of the centromeric histone variant Cse4

In order to gain insight into the function of the Saccharomyces cerevisiae SWI/SNF complex, we have identified DNA sequences to which it is bound genomewide. One surprising observation is that the complex is enriched at the centromeres of each chromosome. Deletion of the gene encoding the Snf2 subunit of the complex was found to cause partial redistribution of the centromeric histone variant Cse4 to sites on chromosome arms. Cultures of snf2Δ yeast were found to progress through mitosis slowly. This was dependent on the mitotic checkpoint protein Mad2. In the absence of Mad2, defects in chromosome segregation were observed. In the absence of Snf2, chromatin organisation at centromeres is less distinct. In particular, hypersensitive sites flanking the Cse4 containing nucleosomes are less pronounced. Furthermore, SWI/SNF complex was found to be especially effective in the dissociation of Cse4 containing chromatin in vitro. This suggests a role for Snf2 in the maintenance of point centromeres involving the removal of Cse4 from ectopic sites

Genomic agonism and phenotypic antagonism between estrogen and progesterone receptors in breast cancer

The functional role of progesterone receptor (PR) and its impact on estrogen signaling in breast cancer remain controversial. In primary ER+ (estrogen receptor-positive)/PR+ human tumors, we report that PR reprograms estrogen signaling as a genomic agonist and a phenotypic antagonist. In isolation, estrogen and progestin act as genomic agonists by regulating the expression of common target genes in similar directions, but at different levels. Similarly, in isolation, progestin is also a weak phenotypic agonist of estrogen action. However, in the presence of both hormones, progestin behaves as a phenotypic estrogen antagonist. PR remodels nucleosomes to noncompetitively redirect ER genomic binding to distal enhancers enriched for BRCA1 binding motifs and sites that link PR and ER/PR complexes. When both hormones are present, progestin modulates estrogen action, such that responsive transcriptomes, cellular processes, and ER/PR recruitment to genomic sites correlate with those observedwith PR alone, but not ER alone. Despite this overall correlation, the transcriptome patterns modulated by dual treatment are sufficiently different from individual treatments, such that antagonism of oncogenic processes is both predicted and observed. Combination therapies using the selective PRmodulator/antagonist (SPRM) CDB4124 in combination with tamoxifen elicited 70% cytotoxic tumor regression of T47D tumor xenografts, whereas individual therapies inhibited tumor growth without net regression. Our findings demonstrate that PR redirects ER chromatin binding to antagonize estrogen signaling and that SPRMs can potentiate responses to antiestrogens, suggesting that cotargeting of ER and PR in ER+/PR+ breast cancers should be explored
