A STUDY OF OLDER STUDENTS ATTENDING UNIVERSITY CLASSES

Recently, March, Hooper, and Baum (1977) described a sample of 99 nonstudent elders in terms of their demographic characteristics and their attitudes toward lifelong learning. The sample was found to be well‐educated (mean years of education = 13.61, SD = 9.43), active in the community, well‐read, and fairly affluent. The majority demonstrated a quite open attitude toward the appropriateness of formal education in old age, but also felt that learning can be acquired outside the classroom: “living is learning.”

The present study was undertaken to similarly describe a sample of elderly people enrolled in the University of Wisconsin guest student program, and to contrast these respondents with those in the earlier study. The student group was found to be significantly younger than the nonstudent group (mean = 70.78, SD = 7.21 vs. mean = 74.69, SD = 8.45; t = 2.87, p < .001). Although there is no difference in the mean years of education of the two groups, there is significantly greater variability in years of education in the student group (F = 10.98, p < .001), with 50.4% of the nonstudent group versus 21.6% of the student group having 12 years of education or less. Additionally, it was found that only 10 of the 139 student respondents did not have either personal or vicarious personal (through familial significant others) experience with higher education in youth.

The respondents’ stated preference for class format and student group age is also summarized, and some implications for educational gerontology are discussed.     

Work/training programs for international health science librarians in American medical school libraries

World understanding is more than a desirable goal today: it may be crucial to our survival. Many universities realize this and have in the past decade spent a great deal of time and money to ensure a steady flow of faculty and students between the U.S. and other countries. Librarians with faculty or academic status may benefit from promoting such relationships themselves. Job exchanges and training programs offer librarians in the United States the opportunity to become acquainted with their counterparts in other countries. Such programs enable librarians of various countries to become aware of one another's special needs and common problems, and allow them to share ideas and expertise. This paper presents an overview of international training programs for foreign librarians in the United States, focusing on programs for health sciences librarians in United States medical school libraries. Information is given on the availability and types of institutionally sponsored programs, as well as on MLA's Cunningham Fellowship Program. Some of the difficulties and the benefits of such programs are discussed.

Spontaneous Tumor Lysis Syndrome in an Infant: A Case Report

Tumor lysis syndrome has been observed in patients with malignancies with high cellular burden and high cell turnover, tumor sensitive to therapy, especially after initiating medical treatment. It very rarely occurs spontaneously. The case described here is of 6 months male infant who presented with fever since 1 month and loose stools associated with blood since 15 days. The laboratory investigations showed lactate dehydrogenase (LDH) of 6,192 IU/L and serum uric acid 18.2 mg/dl along with pancytopenia. The infant presented with electrolyte abnormalities and renal failure.     

Impact of age on haematological markers pre- and post-marathon running

This study investigated whether haematological markers differ between young and masters marathon participants, running at similar performance levels. Nine young (31.89 ± 4.96 years) and eight masters (63.13 ± 4.61 years) runners participated. At five time points (pre-race through 54 h post-race), a complete blood cell count, basic metabolic panel and creatine kinase (CK) isoenzyme panel were assessed. Race performance was standardised using the World Masters Association Age Grading Performance Tables. Total CK levels were elevated for all participants at all time points post-race (P < 0.001). The CK-isoenzyme MB% was elevated across groups at 6, 30 and 54 h post-race (P < 0.01, P < 0.01 and P < 0.05), with masters runners having a higher CK-MB% at 30 and 54 h (P < 0.05, P < 0.05). Total white blood cell and neutrophil counts were elevated through 6 h post-race (P < 0.001), with higher levels found in younger runners (P < 0.001). When considering all blood work, masters runners had a higher number of abnormal values at 6, 30 and 54 h post-race (P < 0.05, P < 0.01 and P < 0.05). In conclusion, masters runners demonstrated sustained CK-MB elevation, which may suggest greater cardiac stress. However, future studies using additional cardiac markers should be completed to confirm these findings. In addition, masters runners showed an increased number of laboratory values outside normal range, indicating the body’s reduced capacity to respond to marathon running.
