The Health Disparities Field Experience: College students and community health workers in the field.

CONTEXT: Immersing students studying health promotion and disease prevention into community settings facing health disparities is an essential supplement to their academic experience. As part of many public health professions, these students will likely need to understand the values and beliefs of different cultures so that decisions of appropriate health promotion and treatment can be made equitably. This paper evaluates an education immersion program that was part of a National Cancer Institute funded collaboration supporting the recruitment and training of university students in cancer research. The primary aim of the Health Disparities Field Experience (HDFE) was to facilitate an experience for students pursuing a health-related degree to understand the conceptual issues in border/rural health and the cultural contexts related to health disparities among medically and financially indigent populations in the region. SUBJECTS AND METHODS: This study was conducted using qualitative research methods using a variation of the content analysis approach using open codes to categorize the data. Six students were selected to participate in the HDFE (five graduate students and one undergraduate) and all six of the participants completed pre- and post-test surveys. RESULTS: From the analysis of the data, posttest qualitative responses indicated that three participants saw racism as a primary cause of cancer-related disparities, a change from their pretest responses. When asked about the personal impact of the HDFE, respondents mentioned the importance of the experiential component. CONCLUSIONS: Participants learned about health disparities from the HDFE and expressed high satisfaction with this approach to education.

Long-term tracking demonstrates effectiveness of a partnership-led training program to advance the careers of biomedical researchers from underrepresented groups.

The demographic profile of the biomedical workforce in the U.S. does not reflect the population at large, raising concerns that there will be insufficient trained researchers in the future, and the scope of research interests will not be sufficiently broad. To diversify and expand the pool of researchers trained to conduct research on cancer and cancer health disparities, a series of training activities to recruit and train primarily Hispanic students at both the undergraduate and graduate level were developed. The strengths of both a Hispanic Serving Institution and an NIH-designated Comprehensive Cancer Center were leveraged to develop appropriate research training and professional development activities. The career progression of the participants and degree completion rates was tracked, along with persistent interest in biomedical research in general and cancer and cancer health disparities research in particular for these underrepresented individuals. Finally, this report demonstrates that these training activities increased general knowledge about cancer among participants.

Understanding and reducing obstacles in a collaboration between a minority institution and a cancer center.

Reducing the cancer incidence and mortality rates of underserved populations will require multidisciplinary efforts involving diverse teams of investigators. We describe a collaborative program between a National Cancer Institute-designated cancer center and a minority-serving institution. The organizations worked together to discover institutional and cultural barriers and facilitators to productive collaboration.

Strategies for diversifying the pool of graduate students in biomedical sciences.

As part of our National Cancer Institute-sponsored partnership between New Mexico State University and the Fred Hutchinson Cancer Research Center, we implemented the cancer research internship for undergraduate students to expand the pipeline of underrepresented students who can conduct cancer-related research. A total of 21 students participated in the program from 2008 to 2011. Students were generally of senior standing (47%), female (90 %), and Hispanic (85 %). We present a logic model to describe the short-, medium-, and long-term outputs of the program. Comparisons of pre- and post-internship surveys showed significant improvements in short-term outputs including interest (p<0.001) and motivation (p<0.001) to attend graduate school, as well as preparedness to conduct research (p=0.01) and write a personal statement (p=0.04). Thirteen students were successfully tracked, and of the nine who had earned a bachelor's degree, six were admitted into a graduate program (67 %), and four of these programs were in the biomedical sciences.

Undergraduate cancer training program for underrepresented students: findings from a minority institution/cancer center partnership.

Students from racially/ethnically diverse backgrounds are underrepresented in graduate programs in biomedical disciplines. One goal of the Minority Institution/Cancer Center partnership between New Mexico State University (NMSU) and the Fred Hutchinson Cancer Research Center (FHCRC) is to expand the number of underrepresented students who are trained in cancer research. As part of the collaboration, a summer internship program has been organized at the FHCRC. The program runs for 9 weeks and involves mentored research, research seminars, coffee breaks, social activities, and a final poster session. This study examined the graduate school attendance rates of past interns, explored interns' perceptions of the training program, and identified ways to improve the program. Thirty undergraduate students enrolled at NMSU participated in the internship program from 2002 to 2007 and telephone interviews were conducted on 22 (73%) of them. One-third of the students were currently in graduate school (32%); the remaining were either working (36%), still in undergraduate school (27%), or unemployed and not in school (5%). Students rated highly the following aspects of the program: mentored research, informal time spent with mentors, and research seminars. Students also reported the following activities would further enhance the program: instruction on writing a personal statement for graduate school and tips in choosing an advisor. Students also desired instruction on taking the GRE/MCAT, receiving advice on selecting a graduate or professional school, and receiving advice on where to apply. These findings can inform the design of internship programs aimed at increasing rates of graduate school attendance among underrepresented students.

Green tea extract inhibits the lymphatic absorption of cholesterol and alpha-tocopherol in ovariectomized rats.

Evidence indicates that green tea consumption lowers the serum level of cholesterol (CH). This study was conducted to determine whether green tea lowers the intestinal absorption of CH and other lipids in ovariectomized (OX) rats. OX rats with lymph duct cannulae were infused at 3.0 mL/h for 8 h via an intraduodenal catheter with a lipid emulsion containing (14)C-cholesterol ((14)C-CH) and alpha-tocopherol (alphaTP) without (GT0) or with green tea extract standardized to 42.9 mg (GT1) or 120.5 mg (GT2) of total catechins in PBS (pH 6.5). Green tea extracts dose-dependently reduced (P < 0.05) the lymphatic absorption of (14)C-CH. The cumulative absorptions of (14)C-CH in rats infused with GT0, GT1 and GT2 were 36.3 +/- 1.1, 20.7 +/- 4.3 and 4.8 +/- 4.1% dose, respectively. The percentage distribution of esterified CH did not differ between rats infused with GT0 and GT1 (80.2 +/- 2.3% vs. 79.0 +/- 1.7%), but was significantly lower in those given GT2 (69.1 +/- 6.8%). The absorption of alphaTP also was significantly reduced by GT1 (736.5 +/- 204.9 nmol, 20.8 +/- 5.8% dose) and GT2 (281.0 +/- 190.8 nmol, 7.9 +/- 5.4% dose) compared with GT0 (1048.8 +/- 174.9 nmol, 29.6 +/- 4.9% dose). The absorption of fat was significantly increased by GT1 (862.6 +/- 151.1 micromol) but lowered by GT2 (557.9 +/- 252.2 micromol) relative to GT0 (717.7 +/- 39.1 micromol). The findings provide direct evidence that green tea has a profound inhibitory effect on the intestinal absorption of CH and alphaTP in OX rats. Whether the inhibitory effect of green tea extract is attributable to a specific catechin(s) and other components in green tea remains to be determined.
