Influences on the Selection of Dietetics as a Career

Objective To gather information on the factors that influence students’ decisions to choose dietetics as a career.Design Self-administered questionnaires regarding the point at which career decisions were made were completed by 1,695 students in Plan IV/V dietetics programs throughout the United States.Subjects All Plan IV/V dietetics programs that reported greater than five graduates in the academic year 1989 to 1990 were selected from the 1990-1991 Directory of Dietetic Programs for the sample population. Of the 156 schools that were mailed questionnaires, responses were received from 84 schools (54%). Almost 90% of the students were women, 10.6% were men.Statistical analyses Data were analyzed using the Statistical Package for the Social Sciences. A χ² analysis was used to examine the relationship between point of decision and factors that influenced career choice, including people who influence career choice.Results The majority of students (55%) questioned reported making their career decision in college. Students rated interest in nutrition (96.3%) and job enjoyment (93.8%) as factors that were important in their decision to pursue a career in dietetics. College catalogs were rated by 48.3% of the students as being either useful or very useful in helping them make their career selection. With respect to gender differences, women rated a diverse work environment as being very important to their career decision more frequently than men (χ²=15.44, P<.01). Women were more likely than men to rate part-time work opportunities as being very important (χ²=26.75, P<.001); and selected working with people as being very important to their career decision (χ²=17.59, P<.01).Conclusions Findings identified that recruitment strategies need to be audience specific. Because career decision making appears to occur during one of three time frames (high school, college, or work experience), recruitment activities should be developed to specifically target students at these times. One way to increase the exposure of students to the profession of dietetics is for registered dietitians to give guest lectures in introductory college courses and high school upper-class courses in health, home economics, and biology. The use of university/college catalogs as effective marketing tools should also not be underestimated.Data suggest that gender differences exist in factors that influence persons to choose dietetics as a career. To increase the number of men who pursue careers in dietetics, future research should be designed to more fully explore gender differences, so that strategies to recruit more men into the profession can be developed.

The palmar radiocarpal ligaments: A study of adult and fetal human wrist joints

The palmar radiocarpal ligaments were studied with use of fifty-four dissected adult cadaver wrists and serial sections on twenty-three wrists from fetuses ranging in size from 23 to 230 millimeters crown-rump length. Three palmar radiocarpal ligaments were clearly identified: the radioscaphocapitate, long radiolunate, and short radiolunate ligaments. The radioscaphocapitate ligament originates from the radial styloid process and inserts into the radial aspect of the waist of the scaphoid, hemicircumferentially around the distal pole of the scaphoid and interdigitates with fibers from the palmar aspect of the triangular fibrocartilage complex just palmar to the head of the capitate, with only a minor insertion distally into the body of the capitate. The long radiolunate ligament originates just ulnar to the radioscaphocapitate ligament, being separated from it throughout its course by the interligamentous sulcus. The long radiolunate supports, but is separate from, the palmar aspect of the scapholunate interosseous ligament, and inserts into the radial half of the palmar surface of the lunate. The short radiolunate ligament, previously not described, originates just palmar to the lunate facet of the distal radius articular surface and inserts as a flat sheet of fibers into the proximal margin of the palmar surface of the lunate. Each ligament is intracapsular, enveloped within a continuous superficial fibrous stratum and deep synovial stratum.     

Budesonide versus prednisolone retention enemas in active distal ulcerative colitis

Methods: Efficacy and safety of the topically acting glucocorticosteroid budesonide retention enema (2.3 mg/ 11 5 mL) were compared with prednisolone disodium phosphate enema (31.25 mg/125 mL) in patients with active distal ulcerative colitis. The study was a randomized, multicentre trial, with two parallel groups and single-blind to the investigator. One hundred patients with active ulcerative colitis, not reaching beyond the splenic flexure as determined by endoscopy, were treated for up to 8 weeks. Results: Forty-five patients were randomized to receive budesonide and 5 5 to prednisolone. Both treatment groups improved significantly in terms of endoscopic and histological scoring during the study, but there were no statistically significant differences between the two groups. Clinical remission, defined as no more than three daily bowel movements without blood and endoscopically non-inflamed mucosa, was achieved in 16% of the patients in the budesonide group after four weeks and in 24% in the prednisolone group (N.S.). After 8 weeks treatment the clinical remission rate in the groups had increased to 36 % for budesonide and 47% for prednisolone (N.S.). Mean morning plasma cortisol levels were unchanged in the budesonide group, whereas they were significantly suppressed in the prednisolone group after 2, 4 and 8 weeks (P < 0.0001). Side effects were mild and rare in both groups. Conclusions: Treatment with budesonide enema in active distal ulcerative colitis was comparable, regarding efficacy, to treatment with conventional prednisolone enema. A prolongation of the treatment time from 4 to 8 weeks doubled the clinical remission rate in both groups. However, budesonide may be preferable to prednisolone since it causes less systemic effects as reflected by a lack of plasma cortisol suppression.     

Reconstruction of the lateral tibial plateau using a vascular pedicled patellar transplant

A case of surgical reconstruction in posttraumatic necrosis of the lateral tibial plateau after impression fracture is presented. Joint reconstruction was performed by transposition of the distally pedicled lateral third of the patella combined with a cancellous bone graft. The surgical procedure is described and the indications for it are discussed.     

Quality Ratings of a Hospital Foodservice Department by Inpatients and Postdischarge Patients

Objectives To examine quality of food and nutrition services using the ratings of inpatients and patients who had been discharged (postdischarge patients).Design Questionnaires were used to collect perceptions of inpatients and postdischarge patients on the quality of food and nutrition services. A 5-point scale allowed subjects to rate quality from very poor to very good.Subjects Questionnaires were completed by 252 inpatients and 437 postdischarge patients of a midwestern teaching hospital.Statistical analysis Analysis of variance was used to assess differences in quality ratings on the basis of demographic variables. Stepwise regression was used to determine variables that best predicted overall satisfaction. Paired t tests were conducted to compare matched inpatient and postdischarge ratings.Results Ratings of food and nutrition services indicated that patients were satisfied; few differences were found in ratings on the basis of patient demographics. Food quality was the best predictor of overall satisfaction for both inpatients and postdischarge patients. As patient expectations were increasingly met or exceeded, patient ratings of quality increased. The majority of patients in the matched sample gave the same ratings on the inpatient and postdischarge questionnaires.Applications Foodservice managers who desire to improve patient satisfaction should focus attention on meeting or exceeding patient expectations for food quality.

Precision of dual-photon absorptiometry

Summary Precision of dual-photon absorptiometry (DPA) measurements was determined in a lumbar spine phantom and in humans. Approximately half of the measurements were made before and half after a¹⁵³gadolinium source change. The phantom was measured with different amounts of acrylic, which simulates human soft tissue, in order to evaluate the influence of body thickness on bone mineral density (BMD). Results of scans analyzed with two software versions from Lunar Radiation Corp., the widely used 08B and a prototype 08C, are compared. DPA with a cold source significantly overestimated BMD in the phantom in the presence of large amounts (more than 25 cm) of soft tissue equivalent with version 08B but not with the newer version 08C. Similiarly, in nine subjects, there was a significant decrease in spine BMD after a source change when scans were analyzed with version 08B (mean difference 0.026 g/cm²,P=0.002) but not with 08C (0.01 g/cm²,P=0.234). No systematic effect of source change on femoral BMD measurements was observed. The SD of the mean difference of two measurements of the nine subjects was 0.019 g/cm² (1.6% of the mean value) for the spine with software version 08B and 0.024 g/cm² (2.0%) with version 08C, 0.03 g/cm² (3.3%) for the femur neck, 0.03 g/cm² (4.0%) for the greater trochanter, and 0.04 g/cm² (4.9%) for Ward's triangle region of the proximal femur. The spine phanton was scanned on two other commercial bone densitometers in order to assess inter-instrument variation. Phantom measurements of L2-4 BMD made on two Lunar Radiation Corp model DP3 scanners which differed by 2% were 10 and 12% higher than those with a Norland Corp. model 2600 scanner.
