Read about changes for the Ovid Healthstar database in the 2001 Ovid Healthstar News!
Ovid Healthstar is comprised of data from the National Library of Medicine's (NLM) MEDLINE and former HealthSTAR databases. As such, it contains citations to the published literature on health services, technology, administration, and research. It focuses on both the clinical and non-clinical aspects of health care delivery. The following topics are included: evaluation of patient outcomes; effectiveness of procedures, programs, products, services and processes; administration and planning of health facilities, services and manpower; health insurance; health policy; health services research; health economics and financial management; laws and regulation; personnel administration; quality assurance; licensure; and accreditation.
As announced in October 2000, Ovid is offering Ovid Healthstar as a continuation of the National Library of Medicine's (NLM) now-defunct HealthSTAR database. Ovid Healthstar retains all existing backfile HealthSTAR citations and is updated with new journal citations culled from MEDLINE using the NLM's HealthSTAR search strategy. The database contains citations and abstracts (when available) to journal articles, monographs, technical reports, meeting abstracts and papers, book chapters, government documents, and newspaper articles from 1975 to the present. Citations are indexed with the National Library of Medicine's Medical Subject Headings in order to ensure compatibility with other NLM databases. Information in Ovid Healthstar is derived from MEDLINE, the Hospital Literature Index, and selected journals.

Title Understanding the pathogenesis of type 2 diabetes: can we get off the metabolic merry-go-rounds?. [Review] Source Australian & New Zealand Journal of Medicine. 25(6):870-5, 1995 Dec. NLM Journal Code 9h9 Abstract The aetiology of non-insulin-dependent diabetes mellitus (NIDDM) is not known. The concordance of NIDDM in identical twins and differences in the prevalence rate of NIDDM between different racial groups suggest a genetic cause. Hyperglycaemia in established diabetes is caused by a combination of hepatic insulin resistance, impaired peripheral (muscle and fat) glucose uptake and a defect in glucose-mediated insulin secretion. However, it is not known if these defects are all inherited or if one can cause the others. This uncertainty is due to the fact that hyperglycaemia per se can cause defects in insulin action and insulin secretion that resemble those found in NIDDM. Furthermore the elevated free fatty acid (FFA) levels found when NIDDM is associated with obesity are known to cause both peripheral and hepatic insulin resistance. Recently we have demonstrated the mechanism by which elevated FFA levels can cause hepatic insulin resistance. However, we also have evidence that the converse holds in that genetically engineered hepatic insulin resistance in a transgenic rat model leads to obesity. Thus an understanding of the pathogenesis of NIDDM is complicated by the fact that hyperglycaemia and obesity can be both causes and consequences of insulin resistance. To overcome these difficulties, studies in young euglycaemic diabetes-prone subjects have been conducted. Results suggest that there may be different causes for NIDDM in different racial groups.

Title The ecology of dogs and canine rabies: a selective review. [Review] Source Revue Scientifique et Technique. 12(1):51-71, 1993 Mar. NLM Journal Code a9r Abstract Although dogs are the most widespread and abundant of all carnivores, the role of the dog in human cultures and its impact on the environment have rarely been studied. These subjects are reviewed in the context of canine rabies. To understand the epizootiology of canine rabies, the ecology and population biology of the dog must be considered. Information on dog populations (in relation to different habitats, cultures, social strata of human populations and epizootiological situations) was collected in Nepal, Sri Lanka, Switzerland and Tunisia. In Switzerland (and Western Europe in general), rabies is maintained and spread by red foxes. The low prevalence of rabies in dogs may be explained by restrictive practices of dog-keeping and high rates of vaccination. In the other areas examined, dogs are poorly supervised and their population densities are high enough to support rabies, although it is questionable whether canine rabies exists independently of a wildlife reservoir. Dog-keeping practices, high rates of exposure and various cultural factors may lead to a high human rabies mortality rate. Nevertheless, dogs in these areas remain sufficiently accessible for vaccination and well-executed control programmes could prove successful.
