Sexual risk-taking and HIV testing among health workers in Zambia

Abstract: Health workers (N=692) in five Zambian hospitals were interviewed to assess HIV/AIDS risk-taking and status awareness. They comprised of physicians, nurses, clinical officers and paramedics. Only 33% had been tested for HIV and only 24% said their partner had been tested. 26 percent of sexually active respondents had multiple partners; thirty-seven percent of these had not used condoms. Only 60% of respondents believed condoms were effective in preventing HIV. Women were less likely to trust or use condoms even in high-risk relationships. The data suggest a need to develop HIV/AIDS programs for health workers, with emphasis towards gender-based obstacles hampering safer behaviors.

Simulation of the mixed-mode natural-convection solar drying of maize

Abstract: A mathematical model for mixed mode natural convection solar drying of maize grain is presented. The drying is described by a deep bed procedure that includes conduction within the grain bed. The conduction is due to radiative energy falling on the upper surface of the bed. The results show that temperatures at the top and bottom of the bed are higher than that in the middle resulting in two drying fronts one at the top and the other at the bottom of the bed and moving in opposite directions. This results in more uniform moisture content distribution than in an indirect dryer. The results are verified against experimental data from a prototype mixed mode natural convection maize solar dryer. The laboratory solar dryer was constructed at Newcastle University, U.K. and the experiments carried out under a solar simulator. The agreement between theory and experiment is very good.

Seroprevalence and determinants of toxoplasmosis in pregnant women attending antenatal clinic at the university teaching hospital, Lusaka, Zambia.

Abstract: Toxoplasmosis is a neglected zoonotic disease which is prevalent among pregnant women especially in Africa. This study aimed to determine the seroprevalence and determinants of the disease among pregnant women attending antenatal clinic at the University Teaching Hospital (UTH). A cross-sectional study was employed where 411 pregnant women attending antenatal clinic at UTH were interviewed using closed ended questionnaires. Their blood was also tested for Toxoplasma gondii IgG and IgM antibodies using the OnSite Toxo IgG/IgM Combo Rapid test cassettes by CTK Biotech, Inc, USA. The overall seroprevalence of the infection (IgG) was 5.87%. There was no seropositive IgM result. Contact with cats showed 7.81 times the risk of contracting the infection in the pregnant women and being a farmer/being involved in construction work showed 15.5 times likelihood of contracting the infection. Socio-economic status of the pregnant women also presented an inverse relationship (showed association) with the infection graphically. However, though there were indications of association between contact with cats, employment type as well as socioeconomic status of the pregnant women with the infection, there was not enough evidence to suggest these factors as significant determining factors of Toxoplasma gondii infection in our study population. There is a low prevalence of Toxoplasma gondii infection among pregnant women in Lusaka, Zambia. Screening for the infection among pregnant women can be done once or twice during pregnancy to help protect both mother and child from the disease. Health promotion among women of child bearing age on the subject is of immense importance in order to help curb the situation. Further studies especially that of case–control and cohort studies should be carried out in the country in order to better ascertain the extent of the condition nationwide.

Tuberculous meningitis: a roadmap for advancing basic and translational research

Abstract: Tuberculous meningitis is a serious, life-threatening disease affecting vulnerable populations, including HIV-infected individuals and young children. The US National Institutes of Health convened a workshop to identify knowledge gaps in the molecular and immunopathogenic mechanisms of tuberculous meningitis and to develop a roadmap for basic and translational research that could guide clinical studies.

Promoting Renewable Energy Technologies for Rural Development in Africa: Experiences of Zambia

Abstract: The need to meet the growing energy demand from Zambia's growing economy and the large number of un-electrified households has been the major driver towards the introduction of renewable energy technology in the country. This study is based on a review of planning and policy documents, a household questionnaire survey and interviews with energy institutions, planners and rural development organisations. The paper examines Zambia's efforts to exploit renewable energy technology. The paper reveals a growing interest in renewable energy among policy makers and planners. Attempts have been made to integrate renewable energy technologies in development policy and plans. The study also shows that the use of renewable energy in rural Zambia is limited mainly to solar energy technologies with minimal exploitation of wind energy technology. However, household use of solar energy technologies in the form of solar home systems is limited to an elite group of rural population that is mostly in formal and / or government employment. The challenges of renewable energy use in Zambia include inadequate policy provision and implementation, lack of awareness among rural households about the benefits of renewable energy, the high cost of technology and the undeveloped nature of renewable energy markets.
