Cholesterol screening: observed cholesterol reduction in a prospective study in Norway

The general public of the City of Bergen, Norway was Invitedto participate in a cholesterol screening programme in October1988. Participants received the results of the cholesterol screeningand nutritional information from trained health personnel. Ashort questionnaire was mailed to all 354 participants 1–2weeks after the initial cholesterol screening. In March 1990,all participants were invited to have their cholesterol levelsre-examined. Psychosocial factors believed to be predictiveof future serum cholesterol changes were assessed at baselinealong with demographic variables. The majority of participants(61%) reduced their cholesterol level from October 1988 to March1990, and the average reduction in cholesterol level for thetotal population was 4.0%. Baseline cholesterol levels, beingconfident of one's own ability to change one's diet (self-efficacy),seeing heart disease risk reduction as very important, and maritalstatus were factors that significantly predicted successfulcholesterol reduction 18 months later.     

The applicability and utility of the MMPI-based offender classification system in a correctional mental health unit

This study investigated the applicability and utility of Megargee and Bohn's MMPI-based offender classification system in correctional mental health units (MHUs). Previous studies found that 11 MHU samples (n = 1723) had substantially more offenders classified in the more pathological MMPI types than did 21 samples (n = 5881) drawn from general male populations in US prisons. In this study of 63 severely disturbed felons, 43% belonged to the most pathological type (‘group How’). Comparing MHU patients with general offenders from the same IvfIvIPI types on staff ratings and case history variables, we found that the MHU patients were significantly poorer in adjustment. Within the MHU sample, there was no difference in case history variables or adjustment ratings between those in the most and least severe MMPI types. These findings differed from those of studies using less severely disturbed, more heterogeneous, MHU populations. It was concluded that, in settings in which the entire population is flagrantly disturbed, the MMPI-based system is more useful in screening potential admissions than it is in making meaningful distinctions among those already admitted.     

Progress in Rhesus Histocompatibility Typing Resulting from the Second International Nonhuman Primate Histocompatibility Workshop (1973)

The Second International Nonhuman Primate Histocompatibility Workshop permitted comparison of rhesus monkey alloantisera developd in various laboratories on a single common panel of related and unrelated monkeys. Analysis of the data permits the conclusion that at least nine specificities are recognized by more than one laboratory, including six at the first locus and three at the second locus.     

Seroprevalence of Helicobacter pylori Infection in Urban and Rural Vietnam

Helicobacter pylori-associated diseases, such as peptic ulcer and gastric cancer, are common in Vietnam, but the prevalence of the infection is largely unknown. A validated enzyme-linked immunosorbent assay was used for seroepidemiology with 971 samples from the general population, ages 0 to 88 years, with 546 samples from an urban population (Hanoi), and with 425 samples from a poor, rural province (Hatay). The overall seroprevalence of the infection was 746 per 1,000, with a prevalence of 788 per 1,000 in Hanoi and 692 per 1,000 in Hatay (P = 0.0007). The risk for infection in the rural area of Hatay was 40% lower than in the urban population of Hanoi, with the odds ratio being 0.59 (95% confidence interval, 0.43 to 0.81). The study shows that the prevalence of H. pylori infection is high in Vietnam and especially high in a large urban area, such as the city of Hanoi.     

Inhibition of the Mixed Lymphocyte Culture Response by Antibody Following Successful Human Renal Transplantation

Immunoglobulin G, appearing after several months in the serum of a recipient of a successful kidney transplant from a closely matched sibling donor, was demonstrated to progressively inhibit unidirectional mixed lymphocyte cultures when donor lymphocytes were used either in responding or stimulating cell populations. The active recipient IgG had no effect in cultures in which donor cells were not used, nor did IgG obtained from other individuals show nonspecific inhibitory effects on cultures containing donor cells. It is suggested that the MLC inhibitory immunoglobulin may serve an immunoregulatory function after renal transplantation.
