Increasing the capacity of health sciences to address health disparities.

In order to create a cohort of investigators who are engaged in health disparities research, scholarship, and practice, and to increase the amount of funding in the university that is invested in research focused on reducing health disparities, the San Diego EXPORT Center implemented 2 major initiatives: (1) the support of underrepresented minority (URM) junior faculty development and (2) the funding for pilot research grants in health disparities. This paper describes the activities employed by the center and summarizes the outcomes of these two initiatives. Ninety-five percent (18 of 19) URM junior faculty completed the faculty development program, and 83.3% (15 of 18) of the completers are advancing in their academic careers at University of California San Diego (UCSD) and are teaching, working with populations at risk and/or conducting research in health disparities. EXPORT awarded 7 investigators a total of $429186 to conduct pilot research, and 71.4% (5/7) have now obtained $4.7 million in independent extramural funding. The San Diego EXPORT Center has increased the research capacity, strengthened the infrastructure for health disparities research, and created a cohort of successful URM junior faculty who are advancing in their academic careers. These investigators are already changing the climate at UCSD by their leadership activities, research focus, peer-networking, and mentoring of students.

Career experiences and perceptions of underrepresented minority medical school faculty.

BACKGROUND: Although studies have outlined the benefit of diversity in academic medicine, the number of underrepresented minority (URM) faculty remains low. In 1998, University of California, San Diego (UCSD) School of Medicine with the Hispanic Center of Excellence began a formalized proactive faculty development program. Over the past 10 years, recruitment and retention of URM junior faculty have increased. We undertook a study to explore factors associated with this improvement. METHODS: Semistructured interviews were conducted with 18 out of 26 URM and 12 out of 26 randomly chosen non-URM assistant and associate faculty members throughout 2005. Interview content, based on a conceptual framework from Joanne Moody, included career path, knowledge and experience with faculty development programs and perceived faculty standing. RESULTS: URM faculty were more likely than majority faculty (44% vs. 8%, p = 0.04) to mention the importance of a role model in choosing their career path. URM faculty participated in faculty development programs at a higher rate than majority faculty (78% vs. 17%, p < 0.001), were more likely to find out about programs through personal contact (94% vs. 42%, p = 0.001) and reported more personal contacts prior to participation (78% vs. 33%, p = 0.02). URM faculty were older, graduated earlier and were more likely hired into a staff position prior to faculty appointment (61% vs. 17%, p = 0.02). CONCLUSIONS: Academic medical centers may find competitive URM candidates in staff positions and alternative faculty tracks within their institution. Informing URM faculty often and personally about opportunities for faculty development may increase their participation in career development programs and improve retention.

Navigating between cultures: the role of culture in youth violence.

The purpose of this paper is to review three cultural concepts (acculturation, ethnic identity, bicultural self-efficacy) and their relationship to the known risk and protective factors associated with youth violence. We conducted a review of the relevant literature that addresses these three cultural concepts and the relationship among culture, violent behavior, and associated cognition. The available literature suggests that ethnic identity and bicultural self-efficacy can be best thought of as protective factors, whereas acculturation can be a potential risk factor for youth violence. We examine the connection between these cultural concepts and the risk and protective factors described in the 2001 Surgeon General's Report on Youth Violence, and present a summary table with cultural risk and protective factors for violence prevention. These concepts can assist physicians in identifying risk and protective factors for youth violence when working with multicultural adolescents and their families. Physicians are more effective at providing appropriate referrals if they are aware that navigating among different cultures influences adolescent behavior.

The San Diego East County school shootings: a qualitative study of community-level post-traumatic stress.

INTRODUCTION: Within one month (March 2001), two separate incidents of school shootings occurred at two different high schools within the same school district in San Diego's East County. OBJECTIVE: To examine community-wide expressions of post-traumatic distress resulting from the shootings that may or may not fulfill DSM-IV criteria for post-traumatic stress disorder (PTSD), but which might interfere with treatment and the prevention of youth violence. METHODS: A qualitative study was undertaken using Rapid Assessment Procedures (RAP) in four East San Diego County communities over a six-month period following the two events. Semi-structured interviews were conducted with 85 community residents identified through a maximum variation sampling technique. Interview transcripts were analyzed by coding consensus, co-occurrence, and comparison, using text analysis software. RESULTS: Three community-wide patterns of response to the two events were identified: (1) 52.9% of respondents reported intrusive reminders of the trauma associated with intense media coverage and subsequent rumors, hoaxes, and threats of additional acts of school violence; (2) 44.7% reported efforts to avoid thoughts, feelings, conversations, or places (i.e., schools) associated with the events; negative assessment of media coverage; and belief that such events in general cannot be prevented; and (3) 30.6% reported anger, hyper-vigilance, and other forms of increased arousal. Twenty-three (27.1%) respondents reported symptoms of fear, anxiety, depression, drug use, and psychosomatic symptoms in themselves or others. CONCLUSIONS: School shootings can precipitate symptoms of post-traumatic stress disorder at the community level. Such symptoms hinder the treatment of individuals with PTSD and the implementation of effective prevention strategies and programs.

Dietary phosphorus reduction by pretreatment of human breast milk with sevelamer.

Hyperphosphatemia leading to hyperparathyroidism and ultimately renal osteodystrophy is a well-known complication of chronic renal failure. A new hydrogel binder, sevelamer, has recently become available for use in hyperphosphatemic patients with renal failure. We had previously mixed the capsule with pumped breast milk and formula, but discovered that the hydrogel formed a viscous solution that infants were unable or unwilling to swallow. We therefore evaluated the phosphorus content of fresh and frozen breast milk before and after treating with different doses of sevelamer at different temperatures and for varying lengths of time. The hydrogel bound promptly to phosphorus, reducing the phosphorus content 78% within 5 min. The viscous hydrogel settled to the bottom of the container within 10 min allowing the supernatant to be easily decanted. We also evaluated the breast milk for changes in other electrolytes, osmolality, pH, and macronutrient content. These results show that fresh or frozen breast milk can be safely pretreated with sevelamer without significantly changing its macronutrient or ionic content, with the exception of calcium and protein. The supernatant can be fed to infants or instilled through a gastrostomy tube without difficulty since the viscous hydrogel settles rapidly to the bottom of the container.

Mycobacterial peritonitis in pediatric peritoneal dialysis patients.

Peritonitis is the most common complication and the leading cause of death in pediatric peritoneal dialysis (PD) patients. According to the most recent data available from the North American Pediatric Renal Transplant Cooperative Study (NAPRTCS), approximately 25% of pediatric PD patients who die succumb to infection. There are no reported cases of Mycobacterium tuberculosis (MTB) or Mycobacterium avium-intracellulare peritonitis in the NAPRTCS registry. With an increasing incidence of MTB worldwide and the impairment of cellular immunity in chronic renal failure patients, it is not surprising that mycobacterium peritonitis can occur in PD patients. We report two pediatric PD patients with mycobacterial peritoneal infection diagnosed over an 11-year period at our institution. One patient presented with a malfunctioning Tenckhoff catheter and again 3 years later with hyponatremia and ascites. The other presented with recurrent culture-negative peritonitis. These cases illustrate the importance of more extensive evaluation of PD complications, to include evaluation for mycobacterium with special media or peritoneal biopsy, in the above clinical settings if the routine work-up is unrevealing.
