D.Litt. et Phil. / The condition known as hypertensive encephalopathy has thrust high blood pressure as a factor in cognitive dysfunction into the limelight. The present study seeks to explore this phenomenon, the allied considerations of adrenergic activation and blockade (as induced by the class of anti-hypertensives termed beta-adrenergic antagonists) and their relationship with attention and memory. The main impetus for the thesis derives from the disparate results of studies into the functioning of attention and memory processes in both medicated and unmedicated hypertensives, despite consistent outcomes having emerged from animal studies. An integrative, explanatory psychophysiological model 1s consequently developed to help illuminate this scientific terrain. The study constitutes an analysis of the course and pathogenesis of hypertension, with a specific emphasis on factors that maintain the disease as well as those that serve to lessen its adverse health effects. The association between hypertension and sympathetic nervous system activation receives much attention together with relevant personality and behavioural variables. It is discussed how sympathetic nervous system activation and the failure of certain negative feedback mechanisms relate to hypertension as well as memory consolidation. The disparate study outcomes and explanations regarding the connection between adrenergic activation and memory are traced to certain paradigmatic roots. These include the computer analogy of mental functioning, Cartesian dualist notions and the case of 'HM'. In contrast to, notably, the Cartesian dualist notions, it is shown that body and brain are a necessary unity for memory formation. This unity is explicated through an analysis of baroreceptor function as an example of a 'simple' cybernetic system involved in maintaining regulated cerebral blood flow.

MSc (Nursing), Faculty of Health Sciences, University of the Witwatersrand, 2009 / Pregnancy induced hypertension (PIH) occurring during pregnancy, labour and puerperium is a major contributor to the high percentage of maternal morbidity and mortality in the Eastern Cape Province, and worldwide. In South Africa (SA), PIH is the second most common of all primary causes of maternal mortality reported in the triennium from 1999 to 2001. From 1999 to 2001, PIH was the cause of 20,7 % (n = 507) of all maternal mortalities in SA (Department of Health (DOH), 2001:38). In the light of these statistics and other statistics related to other causes of MMR, the National Confidential Committee on Enquiries into Maternal Deaths (NCCEMD) developed the National Guidelines for Maternity Care in South Africa, a Manual for Clinics, Community Health Centres and District Hospitals. The guidelines related to PIH were of particular interest in this study. A quantitative, descriptive and contextual survey was conducted to determine the implementation of the National Guidelines for Maternity Care for the management of PIH by the midwife at level-1 clinics in the Eastern Cape, and to make recommendations for the management of PIH by midwives at level-1 clinics with the intention of reducing maternal mortality and morbidity due to PIH. The research method comprised a retrospective record review of the records of all patients admitted with PIH at a level-3 hospital who were referred by a midwife from a level-1 clinic. Data were collected by means of a researcher-administered data collection tool based on the iii National Guidelines for Maternity Care in SA for the management of PIH. The researcher wished to determine whether the National Guidelines for Maternity Care in SA was being implemented for the management of PIH by midwives at level-1 clinics in East London. A purposive sample of 290 maternal records of mothers who had been admitted for PIH at level 3 after being referred from level-1 clinics from May 1999 to June 2003 were used. Data were analysed using descriptive statistics. Ethical issues were taken into consideration. Validity and reliability were ensured. In conclusion, given the study findings, the researcher has made recommendations with the intention of reducing mortality due to PHI in the Eastern Cape.
