It is estimated that almost a quarter of a billion people between the ages of 15 and 64 years used an illicit drug in 2013. This corresponds to a global prevalence of 5.2 per cent (range: 3.4-7.0 per cent), suggesting that drug use has remained stable in the past three years, although the estimated number of drug users has actually risen by 6 million to 246 million (range: 162 million-329 milli...

the formulation of global health policy is political; and all institutions operating in the global health landscape are political. this is because policies and institutions inevitably represent certain values, reflect particular ideologies, and preferentially serve some interests over others. this may be expressed explicitly and consciously; or implicitly and unconsciously. but it’s important t...

background: resistance to anti-tuberculosis (tb) drugs is a global problem. previous studies showed that the prevalence of primary mdr-tb is higher and has been increasing. the purpose of this study was to determine the primary drug resistance in strains isolated from patients with smear-positive of the new cases to anti-tb drugs. methods: in this cross-sectional study, 266 smear positive pulmo...

The modern concept of globalization in health care and clinical research often carries a positive message for the "Global South" nations of Africa, South America and Southeast Asia. However, bioethical abuse of participants in clinical trials still exists in the Global South. Unethical studies directed by the "Global North", formed by the medically advanced nations in North America, Western Eur...

In this paper, the author attempts to explore some of the problems connected with the formulation and application of international biomedical ethical guidelines, with particular reference to Africa. Recent attempts at revising and updating some international medical ethical guidelines have been bedevilled by intractable controversies and wrangling regarding both the content and formulation. Fro...

Focuses on the direct and indirect impact of environmental abuse on human wellbeing. In some instances, the impact of environmental abuse on human health is not still unknown, merely being subject to scientific suspicion. This would suggest caution and the need for preventive measures to be applied. The threat to human health from environmental factors is not an isolated problem that exists on ...

The paper shows how to give a direct discrete formulation of the wave equation starting directly from physical laws, i.e. without passing through differential formulation. Using global variables instead of scalar and vector field functions, a close link between global variables and spatial and temporal elements immediately appears. A preliminary classification of physical variables into three c...
