چکیده

Population samples from Angola, Mozambique, and S. Tomé e Príncipe were screened for the TPI gene promoter variants -5A-->G, -8G-->A and -24T-->G. Three haplotypes were identified in the three populations: the haplotype -5A-8G-24T (average frequency 65.3%) and two less common haplotypes -5G-8G-24T (average frequency 24.7%) and -5G-8A-24T (average frequency 10.0%). A population sample from Central Portugal showed the haplotype -5A-8G-24T in 139 chromosomes and one subject heterozygous for haplotype -5G-8A-24G. The exact test of sample differentiation among three groups of malaria-infected individuals classified according to the severity of the disease showed no significant differences. We confirmed TPI gene diversity in sub-Saharan Africa, but we could not detect any association between TPI promoter variation and a malarial protective effect. Larger scale epidemiological studies are thus required to clarify this putative mechanism of natural host defense against this worldwide public health problem.

Is the Role of Physicians Really Evolving Due to Non-physician Clinicians Predominance in Staff Makeup in Sub-Saharan African Health Systems?; Comment on “Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians”

Health workforce shortages in Sub-Saharan Africa are widely recognized, particularly of physicians, leading the training and deployment of Non-physician clinicians (NPCs). The paper by Eyal et al provides interesting and legitimate viewpoints on evolving role of physicians in context of decisive increase of NPCss in Sub-Saharan Africa. Certainly, in short or mid-term, NPCs will continue to be a...

History and structure of sub-Saharan populations of Drosophila melanogaster.

Drosophila melanogaster is an important model organism in evolutionary genetics, yet little is known about the population structure and the demographic history of this species within sub-Saharan Africa, which is thought to contain its ancestral range. We surveyed nucleotide variation at four 1-kb fragments in 240 individual lines representing 21 sub-Saharan and 4 Palearctic population samples o...

Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians

Responding to critical shortages of physicians, most sub-Saharan countries have scaled up training of nonphysician clinicians (NPCs), resulting in a gradual but decisive shift to NPCs as the cornerstone of healthcare delivery. This development should unfold in parallel with strategic rethinking about the role of physicians and with innovations in physician education and in-service training. In ...

Non-physician Clinicians – A Gain for Physicians’ Working in Sub-Saharan Africa; Comment on “Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians”

The changing demands on the health sectors in low- and middle-income countries especially sub-Saharan African countries continue to challenge efforts to address critical shortages of the health workforce. Addressing these challenges have led to the evolution of “non-physician clinicians” (NPCs), that assume some physician roles and thus mitigate the continuing shortage of doctors in these count...

A New Generation of Physicians in Sub-Saharan Africa?; Comment on “Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians”

This commentary follows up on an editorial by Eyal and colleagues in which these authors discuss the implications of the emergence of non-physician clinicians (NPCs) on the health labour market for the education of medical doctors. We generally agree with those authors and we want to stress the importance of clarifying the terminology to describe these practitioners and of defining more formall...
