Prioritizing Residents' Needs: On the Creation of a Residents as Teachers and Leaders Program

Introduction: Residents are responsible for the majority of medical student teaching and directly supervise, instruct, and evaluate students. Many organizations now recommend that residency training programs include venues specifically designed to develop resident teaching skills. [See PDF for abstract].

Health, education and community: Assets and needs of a small urban community in north east Tamaulipas, Mexico: A community based participatory research assessment

This study explored the health, education, social assets, needs, attitudes, and behaviors of residents of Ferrocarril #4, a small urban community in Tamaulipas, Mexico. A collaborative Participatory Action Research approach was used to emphasize community involvement. Using Triangulation to ensure validity, qualitative methods included key informant in depth interviews, participant observation and participatory discussion groups with women and men. A personal interview with a probability sample of women was done. The median age of interviewees was 37 years. The majority was married or had a partner. Over half of respondents completed grades 6-9. Employed women (25%) earned a median weekly salary equivalent to ∼56 USD. Women with health insurance (67.7%) were covered mainly through Social Security and Seguro Popular. One in 5 reported bad health. Barriers to care were primarily money and transportation. To improve health care, women wanted a full service clinic in or close to the community and affordable health care. Socially, 28% of respondents had no close friends in the community and most did not participate in beneficial community activities. Many women did not socialize with others and help from neighbors was situational. Primary school teachers lacked parental support and it interfered with classroom efforts. Healthy community discussion groups focused on personal and environmental hygiene and safety. Valuable assets exist in the community. To date, collaborative efforts resulted in a school First Aid station, a school nurse visit weekly, posting of emergency contact phone numbers in the school and community center, and development of a student health information form. ^

Homeless access to dental health care: Creation of a dental service model

This project involved developing a model for planning a dental emergency treatment center that could function as an embedded component of a shelter for the homeless population. The dental services provided by such a clinic should include treatment for tooth pain, dental caries or cavities, chipped or broken teeth, broken partials, abscessed teeth, emergency cleanings, periodontal disease or gum disease and fillings. These are the dental services that are most often sought by homeless people in hospital emergency rooms.^ The underlying assumption for this project was that the oral health needs of the homeless community can most effectively be addressed by implementing small dental clinics in existing facilities that provide shelter and other services for this population. The model described in this project identifies oral health care services that would be provided by the clinic, facility (physical plant) requirements and associated infrastructure to operate an embedded dental clinic, methods for obtaining funding, strategies of recruiting dental professionals to staff the facility, and methods to assess the outcomes of the embedded clinic strategy. As an example, this project describes a strategy for developing such an embedded clinic at San Antonio Metropolitan Ministries SAMM shelter based on recommendations from community health care leaders, managers of homeless shelters, members of the homeless community and dental professionals^

Creation of a retinoblastoma mutant with dominant -negative activity

The Retinoblastoma tumor suppressor gene (RB) plays a role in a variety of human cancers. Experimental analyses have indicated that the protein product of the RB gene (pRb) plays a role in cell cycle regulation, and that this protein is required in cellular differentiation, senescence, and cell survival. pRb function is dependent on its ability to bind to cellular factors. There are multiple protein binding domains within pRb. Mutations within these domains which eliminate the ability of pRb to bind its targets result in loss of function. Loss of pRb function leads to tumorigenesis, although uncontrolled cellular proliferation is not a universal response to pRb inactivation. The ultimate response to the loss of pRb is influenced by both the genetic and epigenetic environments. Targeted disruption of RB in mice results in embryonic lethality, demonstrating the requirement for functional pRb in development. Close examination of various tissues from the embryos which lack wildtype RB shows problems in differentiation as well as showing induction of apoptosis. Although disruption of RB has provided useful information, complete inactivation of a gene precludes the possibility of discovering the functions that separate domains may have within the system. Creation of a dominant negative mutant by domain deletion whose phenotype is expressed in the presence of the wildtype may provide information about the intermediate functions of the protein. In addition, tissue specific targeting of a dominant negative mutant of pRb allows for comprehensive analysis of pRb function in organogenesis. In this thesis, a series of RB deletion mutants were created and tested for dominant negative activity as well as cellular localization. A tissue culture assay for dominant negative activity was developed which screens for the phenotype of apoptosis due to loss of pRb function. Two mutants from this series scored positive for dominant negative activity in this assay. The effect of these mutants within the assay environment can be explained by a model in which pRb acts as a facilitator of cell fate pathway decisions. ^
