PURPOSE Social network analysis (SNA) provides a way of quantitatively analyzing relationships among people or other information-processing agents. Using 2 practices as illustrations, we describe how SNA can be used to characterize and compare communication patterns in primary care practices. METHODS Based on data from ethnographic field notes, we(More)
The light-harvesting chlorophyll a/b complex (LHC II) and four photosystem II (PS II) core proteins (8.3, 32, 34 and 44 kDa) become phosphorylated in response to reduction of the intersystem electron transport chain of green plant chloroplasts. Previous studies indicated that reduction of the plastoquinone (PQ) pool is the key event in kinase activation.(More)
PURPOSE Care of patients with diabetes requires management of complex clinical information, which may be improved by the use of an electronic medical record (EMR); however, the actual relationship between EMR usage and diabetes care quality in primary care settings is not well understood. We assessed the relationship between EMR usage and diabetes care(More)
Leukemia is the fourth most commonly occurring cancer in the United States population between the ages of 17 and 34 years, an age group heavily represented in the US Navy. Historical computerized military career records maintained at the Naval Health Research Center, San Diego, California, were used to determine person-years at risk (total, 4,072,502(More)
Emergency department (ED) use for non-urgent needs is widely viewed as a contributor to various health care system flaws and inefficiencies. There are few qualitative studies designed to explore the complexity of patients' decision-making process to use the ED vs. primary care alternatives.

Shared decision making is recommended before prostate cancer screening. Little is known regarding reasons why men choose to get or not get prostate cancer screening, particularly in white or Hispanic men. We conducted semi-structured in-depth interviews of 64 men, age 50 years and over, purposively sampled from men who were never screened for prostate(More)
Extensive research has focused on understanding family dynamics of men with prostate cancer. However, little qualitative work has examined the role of family ties on men's prostate cancer decisions across the spectrum of screening, diagnosis, and treatment. Using data from a larger study, we qualitatively explored the influence of family ties on men's(More)
Melanoma is the second most common cancer, after testicular cancer, in males in the U.S. Navy. A wide range of occupations with varying exposures to sunlight and other possible etiologic agents are present in the Navy. Person-years at risk and cases of malignant melanoma were ascertained using computerized service history and inpatient hospitalization files(More)
