Equine leptospirosis has been associated with abortions, renal failure and uveitis, which constitutes a health economic problem. However, it is generally asymptomatic, makes this disease of little interest in equines comparison other domestic wild species. At present, the real epidemiological situation unknown; just as develops these animals. A search scientific literature was carried out; obje...

Introduction: During the last half century, all indices of mortality imply the prompt and continuous decrease of nationwide mortality. Alongside reduction of mortality, there happened a comprehensive form of transition of mortality causes, from epidemical and other communicable diseases such as mothers' (birth giving) mortalities and birth related ones, to other causes like chronic diseases r...

this paper is concerned with global analysis of a delay sveir epidemiological model in a population of varying size. by using lyapunov stability method and lasalle’s invariance principle for delay systems, we prove that when there is no endemic equilibrium, the disease free equilibrium is globally asymptotically stable, otherwise the endemic equilibrium is globally stable.

AIM To describe the epidemiological characteristics of patients with primary intraocular, conjunctival, and orbital cancers seen in Singapore from 1968 to 1995. METHODS Epidemiological data of all cancers diagnosed in Singapore are collected by the Singapore Cancer Registry. The data of all cases of Singapore residents with eye cancers (ICD-9, site 190) were retrieved for analysis. This inclu...

Over the past decade interest in the biochemical and biological properties of polyphenols has grown considerably, as epidemiological evidence for their beneficial effects on health continues to increase. Dietary polyphenol antioxidants are reported to have many ‘health promoting’ properties, including anti-inflammatory, vasoprotection, anti-cancer and anti-obesity effects. However, their absorp...

OBJECTIVE Development of a rational and enforceable basis for controlling the impact of cannabis use on traffic safety. METHODS An international working group of experts on issues related to drug use and traffic safety evaluated evidence from experimental and epidemiological research and discussed potential approaches to developing per se limits for cannabis. RESULTS In analogy to alcohol, ...

On 26 April 2016, thirty years will have elapsed since the occurrence of the Chernobyl accident, which has so far been the most severe in the history of the nuclear reactor industry. Numerous epidemiological studies were conducted to evaluate the possible health consequences of the accident. Since the credibility of the association between the radiation exposure and health outcome is highly dep...

BACKGROUND The data collected by sanitary-epidemiological stations in 2005-2014 were analyzed to determine the incidence rates of borreliosis Lyme disease in the West Pomerania group of workers exposed to tick bites. MATERIAL AND METHODS It was assumed that an adequate comparison of official epidemiological data with the data concerning the number of exposed people, is an indispensable condit...

In this review, we discuss recently accumulated data, analysing genetic influence on leprosy outcome. Most leprosy-related epidemiological studies are based on the comparison of frequencies of genetic markers in case-control designs using candidate genes, mainly on immunological pathways. Genomic scans using family-based designs also identified some chromosome regions to be tested for associati...
