Multicenter Study Comparative Study
Primary care outcomes and provider practice styles.
The purpose of this study was to evaluate change in patient outcomes as a function of practice styles of primary care providers. A prospective, repeated-measures, correlational design was used. Data were collected about (1) providers' self-ratings of practice styles, inclusive of practice model, confidence, autonomy, collaboration, information giving, and job satisfaction, and (2) primary care patients' self-ratings of health status, functional status, information seeking, and satisfaction. ⋯ Practice style did affect patient satisfaction. Patients were least satisfied with providers who scored high on collaboration and most satisfied with providers who scored low on the practice model. Neither provider type nor interpersonal attributes had an effect on health outcomes; sicker patients got better and healthy patients stayed that way.

Comparative Study
Comparison of oxygenated perfluorocarbon and humidified oxygen for rewarming hypothermic miniswine.
This study examines a method to rapidly rewarm the core using total liquid ventilation with warmed, oxygenated perfluorocarbon. Yucatan miniswine were splenectomized and surgically implanted with telemetry devices to transmit electrocardiographic response, arterial pressure, and core temperature. Hypothermia (core temperature = 25.9 +/- 1.3 degrees C) was induced by placing cold-water circulating blankets over the animals. ⋯ Lactate dehydrogenase and aspartate aminotransferase were significantly increased in the control animals compared with the experimental animals. All animals that survived being chilled to 25 degrees C survived rewarming. This method may provide a means of more rapidly rewarming profoundly hypothermic victims while reducing the risks associated with current methods.

This study tested the associations between acculturation and mental and physical health among Hispanic Vietnam veterans. Secondary data analyses of the National Vietnam Veterans Readjustment Survey, an epidemiological study of a representative sample of veterans who served during the Vietnam era (N = 1,195), were conducted. An acculturation index was constructed using standard acculturation measures (range, 0-13), and its predictive validity was tested using nine outcome measures of physical health and eight measures of mental health. ⋯ Mexican Americans and Puerto Ricans did not differ in mental or physical health risk compared with non-Hispanic whites. The association between acculturation and mental and physical health among Hispanics may not be generalized to Hispanic veterans. Hispanics who have been through an intensive assimilating experience, such as being in the military, appear to have health outcomes similar to whites.
