Academic Degrees and Clinical Practice Characteristics: The University of Washington Physician Assistant Program: 1969-2000

CONTEXT: The physician assistant profession has been moving toward requiring master's degrees for new practitioners, but some argue this could change the face of the discipline. PURPOSE: To see if there is an association between physician assistants' academic degrees and practice in primary care, in rural areas, and with the medically underserved. METHODS: Surveys were sent to 880 graduates of the first 32 University of Washington physician assistant classes through 2000. Respondents noted their academic degree at program entry and the highest degree attained at any time up to the time of survey. Relationships between practice characteristics and academic degree levels were tested by unadjusted odds ratios and logistic regression after controlling for year of graduation and sex. RESULTS: Of the 478 respondents, 54% worked in primary care, about 30% practiced in nonmetropolitan communities, and 42% reported providing care for the medically underserved. Respondents with no degree (33% of total at entry, 24% at survey) were significantly more likely than degree holders to work in primary care and nonmetropolitan areas. Respondents with no degree at program entry were significantly more likely, and those with no degree at the time of the survey were marginally more likely, to self-report work with the medically underserved. CONCLUSION: Respondents with no academic degree are significantly more likely to demonstrate a commitment to primary, rural, and underserved health care. These findings may inform the national debate about the impact of required advanced degrees on the practice patterns of nonphysician providers.     

Effects of a very-low-calorie diet and physical-training regimens on body composition and resting metabolic rate in obese females

Sixty-nine obese females received 90 d of a liquid diet providing 2184 kJ/d in clinical trials. Groups were diet only (C), diet plus endurance exercise (EE), diet plus weight training (WT), or diet plus endurance exercise and weight training (EEWT). Changes in body weight, percent fat, fat weight, and fat-free mass were not different between groups. Declines in resting metabolic rate (RMR) were approximately 7% to approximately 12% of baseline values with no differences among groups. A significant increase in work capacity (approximately 16%) was shown for EEWT. Strength index showed declines of approximately 6% for C and EE and gains of approximately 3% and approximately 10% for EEWT and WT, respectively. These clinical trials did not show advantages of any exercise regimen over diet alone for weight loss, body-composition changes, or declines in RMR. Improvements in work capacity were limited and strength improved in groups that participated in strength training.     

Effect of the calcium entry blocker verapamil on renal ischemia

The ability of the calcium entry blocker verapamil to ameliorate the effects of renal ischemia was studied in ten sheep. Postanesthesia, bilateral cutaneous ureterostomies were placed in each sheep to facilitate urine collection and analysis. Both kidneys were made ischemic for one hour by occluding each renal artery. However, immediately before occlusion of the right renal artery, 0.05 mg/kg of verapamil was injected into the artery. Comparison of urinary creatinine excretion and urine volume for 72 h after reversal of ischemia demonstrated that those kidneys pretreated with verapamil had greater functional preservation (p less than .05). In this study, verapamil appeared to provide protection against renal damage after an ischemic insult.     

Advances in the percutaneous management of the ureteropelvic junction and other obstructions of the urinary tract in children

In conclusion, endopyelotomy has been developed over the past several decades on the basis of sound laboratory and clinical research. The success rates have been similar to those of the standard open pyeloplasty, and the procedure is not associated with undue complications. Endopyelotomy has several distinct advantages over open surgery, including the decreased morbidity and associated expense of an open operation, minimal interference with the blood supply of the ureter, and avoidance of removal of the ureter from its natural sheath, preventing the tendency to adhere to adjacent structures and thus kink. As the instrumentation available for percutaneous renal surgery has improved and been miniaturized, the techniques developed in adults have been progressively applied to younger and smaller children. There seems to be little doubt that a comparison of morbidity and socioeconomic factors associated with a successful endopyelotomy versus an open pyeloplasty in adults heavily favors the percutaneous procedures, and judicious application to children would seem warranted. However, the changing presentation of ureteropelvic junction obstruction in children that has resulted from the widespread use of prenatal ultrasonography may make the question moot. Open infant pyeloplasty is a highly successful procedure, accompanied by minimal morbidity and accomplished in a 2- to 3-day hospital stay. The socioeconomic factors are obviated in the infant, who already requires constant maternal care. However, endopyelotomy deserves consideration in the older child, especially if the obstruction is secondary in nature after a previous open procedure.     

Influences of context on early writing development

Research on children's early writing development in the past has focused primarily on product and process. In reviewing the more recent research on early writing development, however, a new focus of context emerges. Occurrences of literacy are now being observed in the home, the school, and the community. With this new emphasis, comes the task of defining context. A definition of context reflects theoretical perspectives, areas of research interests, and types of methodologies employed in conducting research. Therefore, the purpose of this article is to address the following aspects of context: #op1#cp multidiscipline perspectives and definitions of context, #op2#cp contextual shifts observed between the home and the school, #op3#cp contextual factors present when learning how to write, and #op4#cp pedagogical implications for curriculum development.     

Comparison of three immunoassays for diagnosing sensitization to latex in children with spina bifida

As natural rubber latex (latex) has become more widespread in our environment, physicians have become increasingly aware of the problem of possible allergic reactions. Many fatal and near-fatal incidents have been reported (mainly during surgery) (1—3) and data has been published on groups frequently exposed to latex, such as patients with spina bifida (4—9), healthcare professionals (10—12) and occupationally exposed persons (13). The incidence of latex allergy in children seems to be increasing (14). Tests are therefore needed which can reliably detect sensitization to latex. Our aim was to compare the diagnostic accuracy of three commercial immunoassays for measuring specific IgE in serum to latex.     

Physical symptoms/side effects during breast cancer treatment predict posttreatment distress

Background: Studies suggest that the period following completion of treatment can be distressing for cancer patients. One potentially important predictor of distress is physical symptoms/side effects during treatment.Purpose: A longitudinal, observational design was used to examine whether the number of physical symptoms/side effects experienced during treatment was a correlate of cancer-related distress and general distress 4 months after treatment completion, as measured by the Impact of Events Scale and the Mental Health subscale of the Short Form-36, respectively.Methods: Participants were 151 women who had completed chemotherapy and/or radiotherapy for ductal carcinoma in situ or stage 1 or 2 breast cancer. Hierarchical multiple regression was conducted with relevant sociodemographic, clinical, and psychiatric variables entered as controls.Results: Greater physical symptoms/side effects predicted greater total cancer-related distress, intrusive thoughts, and general distress. Physical symptoms/side effects did not significantly predict avoidance. Follow-up analyses indicated that the relationship between physical symptoms/side effects and general distress was mediated by both total cancer-related distress and intrusive thoughts.Conclusions: These results suggest that patients who experience greater physical symptoms/side effects during treatment are at greater risk for later cancer-related distress and, in turn, general distress. Future research should evaluate whether early intervention with these patients is effective in preventing or reducing distress in the posttreatment period.
