Sexual functioning of male anabolic steroid abusers

The effects of anabolic steroid use on male sexual behavior were assessed using a structured clinical interview administered to male body builders currently using steroids, and to two comparison groups (body builders with a past but not current history of steroid use, and a group of natural body builders who had never used steroids). Current anabolic steroid users had a significantly higher coital and orgasmic frequency than did comparison athletes. They also reported a significantly higher incidence of erectile difficulties during the past month. Beliefs concerning the sexually stimulating effects of steroids did not correlate with the frequencies of specific sexual behaviors. The data support the contention that anabolic steroids, as androgenic compounds, enhance sexual desire.     

1992 entry-level athletic trainer salaries

The purpose of this study was to examine the salaries for entry-level positions in athletic training during the year 1992. An entry-level position was defined as an athletic trainer, certified by the National Athletic Trainers' Association (NATA), with no full-time paid employment experience. According to the “Placement Vacancy Notice” published by the NATA, there were 234 entry-level vacancies in the hospital/clinic, 135 with the college/university, and 58 at the high school setting. A survey was designed and mailed to the location of each of these 427 entry-level positions. Distribution of responses was 78 (33%), 55 (41%), and 23 (40%) for hospital/clinic, college/university, and high school, respectively. Overall, beginning salaries for entry-level athletic training positions were $23,108 (± $3,309) for a bachelor's degree and $25,223 (± $3, 794) for a master's degree. A stipend ($4,219 ± $1,458) was included in most of the high school positions. Term of contract for high school was usually 10 months (10.2 ± 0.8 months), hospital/clinic was 12 months (11.9 ± 0.6 months), while the college/university varied from 9 to 12 months (10.8 ± 1.3 months). Further studies are recommended to establish salary norms and trends for entry-level positions so that athletic trainers will understand what monetary compensation is expected for their services.     

Comparison of the precision of two standardized co-ordinate systems for the quantitation of brain anatomy: preliminary results

We assessed reproducible definition of two standardized co-ordinate systems for intersubject analysis of brain images. The baselines in the two co-ordinate systems were a modification of the canthomeatal (inCM) line and the anterior-posterior commissural )AC-PC) line. Axial spin-echo MR images of four subjects at 1.5T were used. Operator error was computed from the replicate analyses of two operators. The mCM line was determined by the lens of the eye and the internal auditory canal, and the AC-PC line was determined by the intersection of the AC and PC with the interhemispheric fissure. Reproducibility of the mCM markers (SD=0.59 mm) did not differ significantly from that of the AC-PC line (SD=0.68 mm). The measurement error of the angle of the baseline (), however, was more than 7 times as large for the AC-PC line as for the mCM line. An additional error affecting the rostrocaudal rotation of the co-ordinate systems, attributable to the distance between the anatomic markers, was 2.1 and 3.6° (3 mm and 5 mm slice thickness) for the mCM co-ordinate system and 8.2 and 11.0° (3 mm and 5 mm slice thickness) for the AC-PC system. The AC-PC line based co-ordinate system is therefore, less reproducible than the mCM line based system. this could be improved if a combination of axial and sagittal images were used for the definition of the AC-PC line.     

Self-rated health and mortality in people with diabetes.

OBJECTIVES. This study examined whether self-rated health is an independent and significant predictor of mortality in people with diabetes, using data collected in the Wisconsin Epidemiologic Study of Diabetic Retinopathy. METHODS. Participants were asked to rate their health in comparison with others their age. A proportional hazards model was used to regress survival time on self-rated health and a number of covariates measuring physical health. RESULTS. People with younger onset diabetes (n = 891) who rated their health relative to their peers as "worse" or "don't know" were no more likely to die than those rating their health as "the same" or "better" when physical health status was controlled. In contrast, those with older onset diabetes (n = 987) who rated their health as "worse" or "don't know" were almost twice as likely to die as those rating their health as "the same" or "better" when physical health status was controlled. CONCLUSIONS. Self-rated health is a significant predictor of mortality in people with older onset diabetes but not in those with younger onset diabetes when physical health status is controlled.     

A study of patients identified as unmanageable prior to admission to an independent medium-secure hospital

A previous study of patient admissions to an independent medium-secure psychiatric hospital by Moss, Green and Naismith (1996) suggested an increased flexibility in the admission of patients identified as having 'exceptional management problems.' In particular this was found to relate to a cohort of 59 patients admitted after having been identified as 'unmanageable' in their parent district. This appeared to provide the impetus, for a number of reasons, for their subsequent referral to the private sector. This study examines the characteristics of these patients, and discusses how the independent sector may be providing a service either unavailable within the National Health Service or for which the National Health Service is unsuitable, in terms of patients either requiring medium- to long-term hospital care in conditions of security, or those who cannot live independently and therefore require 'asylum' (which is no longer available within the National Health Service). In this sense the independent sector could be seen as meeting a national need by acting as a 'safety valve' for National Health Service psychiatric facilities.     

Subclavian and internal jugular veins at Doppler US: abnormal cardiac pulsatility and respiratory phasicity as a predictor of complete central occlusion

In 21 consecutive patients, the authors analyzed changes in venous Doppler waveforms of damped or diminished cardiac pulsatility and respiratory phasicity. Each patient was suspected of having upper limb venous thrombosis, but thrombus was not visible at gray-scale ultrasonography (US) in the subclavian and brachiocephalic veins. US findings were compared with phlebographic findings. The results show that US can be used to establish the presence or absence of thrombosis in the distal portion of the brachiocephalic or subclavian veins, which are inaccessible to direct insonation.     

Is serum cholesterol associated with progression of diabetic retinopathy or macular edema in persons with younger-onset diabetes of long duration?

PURPOSE: To quantitate the relationships of total cholesterol and high-density lipoprotein cholesterol to the incidence and progression of diabetic retinopathy and macular edema 5 years later in those with younger-onset diabetes of long duration. METHODS: Casual serum specimens for lipid values and fundus photography at the time of the lipid determinations were evaluated with regard to retinal lesions in photographs taken 5 years later during the course of a population-based cohort study. RESULTS: Univariable associations were significant for associations of incident retinal lesions with total cholesterol/high-density lipoprotein cholesterol, but multivariable associations considering covariates were not significant. CONCLUSION: Our data suggest that lowering cholesterol by therapeutic means may not be indicated for the sole purpose of decreasing the incidence or progression of these retinal lesions.     

Effect of hydrazine upon vitamin B12-dependent methionine synthase activity and the sulphur amino acid pathway in isolated rat hepatocytes

The effect of the industrial chemical, hydrazine (4-12 mM), on methionine synthase (EC 2.1.1.13) activity and levels of the sulphur amino acids homocysteine, cysteine, and taurine as well as GSH were investigated in vitro in isolated rat hepatocyte suspensions and monolayers in order to explain some of the adverse in vivo effects of hydrazine. None of the concentrations of hydrazine were overtly cytotoxic in hepatocyte suspensions (measured as lactate dehydrogenase [LDH] leakage) after 3 hr. However, after 24 hr in culture cells treated with 12 mM, hydrazine showed a significant increase in LDH leakage. Methionine synthase activity was reduced by hydrazine (8 and 12 mM) in suspensions (by 45 and 55%, after 3 hr) and monolayers (12 mM; 65-80% after 24 hr). This was not due to nitric oxide production and the inhibitor of nitric oxide synthase, Nomega-nitro-L-arginine, failed to protect against the hydrazine-induced loss of ATP and GSH and the reduction in urea synthesis at 24 hr. Homocysteine export was increased by 6 mM hydrazine, and total taurine content of treated cells was increased by 12 mM hydrazine. Thus, hydrazine was found to have several important and possibly deleterious effects on some parts of the sulphur amino acid pathway.
