HIV/AIDS Pandemic in Africa: Trends and Challenges

Three-quarters of the world’s AIDS population lives in Sub-Saharan Africa; most have no access to lifesaving drugs, testing facilities or even basic preventative health care. One of the major factors inhibiting medical professionals in Africa from treating this disease is the inability to access vast areas of the continent with adequately equipped medical facilities. To meet this need, Architecture for Humanity challenged the world’s architects and health care professionals to submit designs for a mobile HIV/AIDS health clinic. The pandemic is changing the demographic structure of Africa and wiping out life expectancy gains. Indeed, in many African countries, life expectancy is dropping from more than 60 years to around 45 years or even less. In this paper, we highlight the uniqueness of factors associated with HIV/AIDS pandemic in Africa and present its impact and challenges.HIV/AIDS, Africa

�We shall have gone to a higher standard�: Training village heath teams (VHTs) to use a smartphone-guided intervention to link older Ugandans with hypertension and diabetes to care

Background: It is not clear whether village health teams (VHTs) can be empowered to participate in interventions to prevent and control hypertension and diabetes in older adults in Uganda. We conducted this study in rural Uganda to establish the experiences of VHTs in managing older adults with health problems, their knowledge of hypertension and diabetes and their understanding of referral systems. We also explored their experiences with smartphones and whether VHTs could be effectively trained to use a smartphone-guided intervention to link older adults with hypertension and diabetes mellitus to care. Methods: We conducted in-depth interviews (IDIs) with and trained 20 VHTs randomly selected from Bukulula sub-county in Kalungu district from October 2017-December 2018. We used interview guides to explore topics relevant to our study objectives. VHTs were trained to measure blood sugar and blood pressure using digital machines. VHTs were trained on identifying symptoms of diabetes mellitus. Data from IDIs were analysed using thematic content analysis. Competence tests were used to evaluate the training. Results: Most of the VHTs were female (75%). All VHTs had some knowledge on hypertension and diabetes and other chronic diseases. They did not have any experience in treating older adults since they had been trained to deal mainly with children. Half of the VHTs owned smartphones. All were willing to participate in an intervention using a smartphone to link older adults with hypertension and diabetes mellitus to care. By the end of the training, all but three participants could comprehend the symptoms of diabetes and measure blood sugar and blood pressure. Conclusion: Village health teams in the study setting need training in managing the health needs of older adults before engaging with an intervention using smartphones to link older adults with diabetes mellitus and hypertension to care.</ns3:p

Data for: Feasibility of village health teams (VHTs) in using a smart phone guided intervention to link older Ugandans with chronic conditions to care

This data collection was produced as part of a feasibility study to determine if Village Health Teams (VHTs) could be trained to use smart phone guided intervention to support older people with chronic conditions. This involved the use of smart phones to record information on residents of the Kalungu district of south-western Uganda and using it to link them to health facilities for the purpose of treatment and care. The collection consists of 20 transcribed interviews, each of which was conducted with a village health team member. Transcripts contain variables on demographic characteristics, activities for VHTs, dealing with older people, linking older people with health problems to care, knowledge on chronic diseases, experiences in using smart phones and willingness to use a smartphone guided intervention in future

Population based haematology reference ranges for old people in rural South-West Uganda

Background: Haematology reference values are needed to interpret haematology results and make clinical decisions, but these have not been established for old people in sub-Saharan Africa. The objective of this study was to establish haematology reference values for people aged 50 years and above in Uganda, to compare the haematology reference values for those aged 65 years and over with those less than 65 years and to compare these haematology reference values with established haematology reference values for old people from high income countries.  Methods: A total of 1449 people aged 50 years and above were recruited from the Medical Research Council/Uganda Virus Research Institute general population cohort between January 2012 and January 2013 (response rate 72.3 %). From the blood samples collected, we did haematology, HIV testing and malaria tests. We also obtained stool samples and tested them for hookworm infection. Questionnaire data were obtained through interviews. In the analysis, we excluded those with HIV infection, malaria infection, hookworm infection and those not feeling well at the time of recruitment. Medians and reference ranges for 12 haematology parameters were determined, based on the Clinical Laboratory and Standards institute's guidelines.  Results: In total, 903 people aged 50 years and above were included in the analysis with the majority 545 (60.3 %) being female. Men had significant difference in median haemoglobin, haematocrit, erythrocytes counts and white blood cells counts, which were higher than those of women. Women had significant difference in mean platelet counts and neutrophil percentages which were higher than those of men. Comparing those aged 65+ and those aged less than 65 years, the following parameters were significantly lower in those aged above 65 years: haemoglobin, haematocrit, erythrocytes counts, platelets and mean corpuscular volume. Compared to the reference intervals from old people in high income countries, all the haematology parameters from our study population were low.  Conclusion: The differences between haematology reference ranges in old people compared to adults and the very old (65+) compared to those between 50 and 65 call for more population based studies using nationwide surveys to be carried out among old people in other study settings in Uganda and the rest of Africa to explore the differences in haematology reference ranges between these different age groups with a view of establishing whether there is need to have separate reference range for these different categories of old people

Mathematical model for pneumonia dynamics among children

The 2012 Southern Africa mathematical sciences association Conference (SAMSA 2012)26th -29th Nov 2012There are major advances which have been made to understand the epidemiology of infectious diseases. However, more than 2 million children in the developing countries still die from pneumonia each year. The eorts to promptly detect, eectively treat and control the spread of pneumonia is possible if its dynamics is understood. In this paper,we develop a mathematical model for pneumonia among children underve years of age. The model is analyzed using the theory of ordinary dierential equations and dynamical systems. We derive the basic reproduction number, R0, analyze the stability of equilibrium points and bifurcation analysis. The results of the analysis shows that there exist a locally stable disease free equilibrium point, Ef when R0 1.The analysis also shows that there is a possibility of a forward bifurcation

They ‘don't cure old age’: older Ugandans’ delays to health-care access

ABSTRACT Uganda's population is ageing, which comes with increased and varied burdens of disease and health-care needs. At the same time, gerontological care in Uganda remains neglected. This paper examines the factors that cause older Ugandans to delay health-care access. We conduct a thematic analysis of data drawn from nine focus groups held with rural Ugandans aged 60-plus. Our analysis highlights the factors that delay older persons’ access to health care and how these align with the Three-Delay Model, which was originally developed to assess and improve obstetric care in low-resource settings. Our participants report delays in deciding to seek care related to mobility and financial limitations, disease aetiology, severity and stigma (Delay I); reaching care because of poor roads and limited transportation options (Delay II); and receiving appropriate care because of ageism among health-care workers, and poorly staffed and under-supplied facilities (Delay III). We find these delays to care are interrelated and impacted by factors at the individual, community and health-system levels. We conclude by arguing for multi-pronged interventions that will address these delays, improve access to care and ultimately enhance older Ugandans’ health and wellbeing

The experiences of caregivers of children living with HIV and AIDS in Uganda: a qualitative study.

BACKGROUND: Home-based care for HIV patients is popular in contexts severely affected by the epidemic and exacts a heavy toll on caregivers. This study aimed at understanding the experiences of caregivers and their survival strategies. METHODS: A total of 18 caregivers (3 males and 15 females) were interviewed using a semi-structured interview guide, and thematic analysis was used to analyse the data. RESULTS: Analysis suggests that the caregivers are burdened with insecure provisions for food and difficulties in accessing health care. They however survived these strains through managing their relationships, sharing burden with care-recipients, social networks and instrumental spirituality. These findings are discussed under two major themes: 1). Labour of caregiving and 2). Survivalism. CONCLUSIONS: Home-based care presents huge opportunities for community response to the HIV/AIDS epidemic in African settings. It is however burdensome and thus should not be left for families alone to shoulder. There is therefore an urgent need for protecting home-based care for HIV children in Uganda. Implications for improving and strengthening social interventions in home-based care of HIV/AIDS in the Ugandan context are addressed

Corporate Image and Organizational Performance of State Owned Enterprises Monitored by Privatization Unit (PU) Uganda

This study was carried out to establish whether corporate image has any influence on organizational performance in state-owned enterprises in Uganda. This was consider relevant as a study area after a realization that state-owned enterprises operate with huge backing from the state unlike the privately owned enterprises. This prompted to ask the big question of whether corporate image has any impact on the overall performance of these entities. A cross sectional research design was adopted for the study. The unit of analysis considered was an entity. The entities were divided into four groups in relation to the industry. Out of a population of 140 firms, 104 were selected to form a sample. All the 103 firms successfully responded representing 100% response rate. In the analysis phase, Correlation and Regression Analyses were used. Findings indicated that Corporate Image of state-owned enterprises has a significant influence on the organizational performance (Sig=0.000; Sig &lt; 0.01; ? = 0.337). Basing on this finding, it has been recommended that the state-owned companies stop counting on the backing of the state and start working on their image so that they can get a wider acceptance in the Ugandan Market.
