Assessment of selected non-communicable diseases in an urban health district of South Africa

Makhudu, Modise Elias 27 March 2015 (has links)
A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Public Health in the field of Hospital Management October, 2014 / Background: The World Health Organization predicts that the deaths related to Non- Communicable Diseases in Africa will rise by 27% over the next decade. As a response to the problem, the National Department of Health in South Africa introduced interventions that focussed on implementing health facility based Non- Communicable Diseases register and a monitoring tool. The Gauteng Department of Health in South Africa started introducing the monitoring tool in public health facilities since April 2011 in a phased manner. This study used a one week data collected in the month of April 2011 in selected health facilities within the Johannesburg Health District. Aim: To describe the socio-demographic and clinical profiles of the study population attending the health facilities in Johannesburg Health District. Methodology: A cross-sectional study design was used for the study. The data was collected from the selected Community Health Centres using the monitoring tool developed by the National Department of Health. The data were collected for a week from randomly selected health facilities in 2011. Results: Nine-hundred and sixty eight study participants were recruited from the five community health centres for the assessment of non-communicable diseases. Among the study participants, the prevalence of hypertension (94.6%) was highest followed by diabetes (39.4%) and hyper-cholesterolaemia (4.6%). A number of study participants had comorbidity associated with all three conditions. The majority of them were 45 years and above (88%), female (53%), and black (98%); There were no significant association between these three conditions and risk factors such as smoking and alcohol drinking. The complications among the study participants include nephropathy, cardiac diseases and retinopathy. Annual screening was done for a number of study participants but it was erratically done so that all study participants were not screened. Twenty-two percent of 968 study participants have blood pressure of more than 140/90mmHg. Twenty percent of study participants have a weight more than 90kg. The sugar level of 22% study participants was more than 7mmol/l. Conclusion: The NCD monitoring tool could be used as an effective tool for management of NCD in PHC setting like Johannesburg Health District.

Transmission of disseminated neoplasia in the soft shell clam, Mya arenaria

House, Marcia 18 September 1997 (has links)
Disseminated neoplasia (DN) is a proliferative cell disorder that occurs in the circulatory system of bivalves. The condition is progressive and lethal. At least 15 species of bivalves over a wide range of geographic locations have been reported to contract DN. Prevalence levels of disseminated neoplasia can reach up to 90% in some populations. In the laboratory, the condition can be transferred to healthy individuals by injection of hemolymph from animals of the same species with high intensity levels of DN. Studies were conducted to investigate transmission of disseminated neoplasia in the soft shell clam, Mya arenaria. It was determined that soft shell clams from two Oregon bays were susceptible to DN by injection, and that the lack of DN in these west coast populations of soft shell clams was not due to disease resistance in these animals. Additionally, it was demonstrated that onset, development of DN, and survival were directly correlated to the number of neoplastic cells injected into the animal. Experiments investigating water-borne transmission showed that the disease is infectious, and an exposure to DN cell in the hemolymph of highly affected clams was sufficient to cause disease. In a cohabitation study, transmission of DN from one DN positive animal to healthy animals was observed, with specific information collected on the length of exposure and DN intensity of the animals involved. Finally, transmission of disseminated neoplasia was not found to be successful using cell-free filtrates prepared from DN cells and DN positive soft shell clam tissue. A PCR enhanced reverse transcriptase assay was employed, and reverse transcriptase activity was detected in samples prepared from DN positive materials. / Graduation date: 1998
