Novel short-term effects of adenovirus Ad-36 on hamster lipoproteins.

OBJECTIVE: Human adenovirus Ad-36 induces adiposity and lowers total serum cholesterol in chickens, mice and marmosets and Ad-36 antibodies are associated with human obesity. We examined the early effects of Ad-36 inoculation on plasma cholesterol levels in hamsters fed a hyperlipidemic diet. DESIGN: A total of 32 male Golden Syrian hamsters were divided into two equal weight-matched groups and intranasally inoculated with Ad-36 (INF: infected) or media (CON: control). In each group, the animals were fed either a purified diet (PF, n=8) 40%en fat +/-194 mg cholesterol/1000 kcal or chow (C, n=8) ad libitum. Animals were killed 5 weeks postinoculation. RESULTS: Nested PCR assay detected Ad-36 DNA in the lung, liver, visceral adipose tissue and skeletal muscle of the INF group, but not in the CON animals. Ad-36 antibodies were detected in the INF group only. For all animals, total plasma cholesterol (TC) was not significantly affected by Ad-36 treatment (203+/-92 vs 193+/-75 mg/dl, P=NS; INF vs CON, respectively). In 5 weeks, Ad-36 infection had no effect on TC concentration in hamsters fed chow (128+/-39 vs 130+/-27 mg/dl, INF-C vs CON-C, respectively) or those fed PF (269+/-70 vs 256+/-47 mg/dl, INF-P vs CON-P, respectively). However, lipoproteins isolated by density gradient ultracentrifugation showed a greater proportion of LDL cholesterol in INF animals, as compared to CON (28.4+/-1.6% vs 16.4+/-1.2%, P=0.02), regardless of dietary treatment (INF-P vs CON-P: 27.3+/-2.1 vs 15.7+/-1.5%, P=0.07; and INF-C vs CON-C: 29.4+/-1.2 vs 17.0+/-1.1%, P=0.009). This shift appears to be from HDL cholesterol to the LDL fractions. CONCLUSION: These data suggest that in the hamster (a model resembling several aspects of human lipoprotein metabolism), Ad-36 infection may acutely affect the intravascular processing of lipoproteins resulting in a more atherogenic lipoprotein profile.

AIDS education in rural Uganda--a way forward.

A survey of acquired immunodeficiency syndrome (AIDS)-related knowledge and attitudes was conducted during July and August 1988 in rural SW Uganda. The aim was to assess the impact of Uganda's AIDS education programme and to consider how future programmes could be more effectively implemented. Four hundred and seventy-six individuals aged 12-45 years were selected by a quota method, to form a sample stratified by age and sex. Mass AIDS education has successfully raised levels of knowledge but misconceptions persist. However, it has failed, firstly, to stress the urgency of AIDS as a personal issue, and secondly, to change negative attitudes toward people with AIDS: 57% would avoid or stigmatise an individual with AIDS. Unexpectedly, findings show that a correlation exists (P less than 0.05) between high levels of 'correct' beliefs and negative attitudes toward people with AIDS. To achieve future behavioural and attitude changes, possible ways forward for Ugandan AIDS education include involvement of HIV carriers in education, small-scale targetted approaches developed by active participation of the target group and through role playing of people with AIDS.

An international perspective on the impact of AIDS and national AIDS education policies and programmes.

During the past decade, the shadow of AIDS has lengthened to touch the lives of many millions of people around the world. The AIDS epidemic is now a global phenomenon with significant social, economic, demographic, legislative and political implications, as well as crucial practical concerns for civil rights, public health and development. This paper considers the growing global impact of AIDS, and attempts a comparative review of national responses, in terms of policies and programmes for AIDS prevention through education and health promotion.

Lake Nyos disaster, Cameroon, 1986: the medical effects of large scale emission of carbon dioxide?

Carbon dioxide was blamed for the deaths of around 1700 people in Cameroon, west Africa, in 1986 when a massive release of gas occurred from Lake Nyos, a volcanic crater lake. The clinical findings in 845 survivors seen at or admitted to hospital were compatible with exposure to an asphyxiant gas. Rescuers noted cutaneous erythema and bullae on an unknown proportion of corpses and 161 (19%) survivors treated in hospital; though these lesions were initially believed to be burns from acidic gases, further investigation suggested that they were associated with coma states caused by exposure to carbon dioxide in air. The disaster at Lake Nyos and a similar event at Lake Monoun, Cameroon, two years previously provide new information on the possible medical effects of large scale emissions of carbon dioxide, though the presence of other toxic factors in these gas releases cannot be excluded.

Lessons from the outbreak of food poisoning at Stanley Royd Hospital: what are health authorities doing now?

The committee of inquiry into the outbreak of food poisoning at Stanley Royd Hospital identified serious deficiencies in the management of the outbreak and urged all health authorities to learn from the incident and prepare adequate plans for dealing with any future outbreaks. A survey of district health authorities in England showed that most authorities do not yet have a written plan or that their plans are incomplete and inadequate. The appreciable resistance to such planning suggests that most health authorities would be unable to deal with outbreaks of food poisoning effectively and efficiently.
