RESUMO
We report on a 2.051 µm InxGaAs/InP-based discrete mode laser diode monolithically integrated with a curved tapered semiconductor optical amplifier for CO2 sensing applications. At a heat-sink temperature of 0°C, the laser emits a record InP value of more than 35 mW continuous-wave output power in a single longitudinal mode.
RESUMO
PURPOSE: To collect information regarding demographics, nutrition-related patient care encounters, and comfort levels in addressing nutrition-related problems in a population of physician assistants (PA) currently practicing in Nebraska. METHODS: A survey was developed by faculty members in the Medical Nutrition Education and Physician Assistant Education programs, School of Allied Health Professions, College of Medicine, University of Nebraska Medical Center. Data were analyzed using descriptive statistics and Fisher's exact test. A P-value of < .05 was considered statistically significant. RESULTS: The return rate of the survey was 70% (N = 266). A high percentage of PAs (86%) reported they often or occasionally encounter nutrition-related issues with patients. In contrast, only 27% of survey respondents felt "very comfortable" in addressing nutrition-related issues. Encountering nutrition issues often and having patients that ask questions about nutrition were significantly associated with a PA's comfort in addressing nutrition issues (P < .001 for both). CONCLUSION: PAs are very likely to encounter nutrition-related issues in their practice. Attention to nutrition-related topics in the PA curriculum and continuing education may be beneficial in increasing the comfort of PAs in addressing these issues.
