Prolonged or untreated intracranial pressure (ICP) can have devastating and life threatening effects. If left untreated, significant brain damage or death can occur as a result of a vicious cycle of destruction. Although clinical signs and symptoms are present with increases in intracranial pressure, ICP monitoring is the "gold standard" for assessment of intracranial pressure. Unfortunately, ICP monitoring is utilized only 50% of the time that it is indicated in the U.S. due to risks such as hemorrhage, infection, and technical malfunctions. Findings in the literature identify variables associated with infection risk when ICP monitoring devices are utilized. Factors associated with an increased risk of infection include indications for monitoring (subarachnoid or intraventricular hemorrhage), concurrent infection, duration and number of devices utilized, manipulation, and dislodgement. Other factors that may be associated with infection risk included corticosteroid use and location where the device is placed. Catheters impregnated with silver or antibiotics are associated with a decreased risk of infection. Variables deemed unimportant in regard to infection risk included age, gender, severity of illness, GCS score, CSF leak, who places the device, routine CSF sampling, prophylactic antibiotics, antibiotic irrigation, and prophylactic catheter exchange. None of the current literature is focused on nursing care. This is unfortunate, as the care nurses provide is integral to infection prevention associated with such devices. Future nursing research must address this lack of imperative information.

Dissertation submitted to the Faculty of Health Sciences, University of Witwatersrand in fulfillment of the Master of Science in Medicine in the School of Physiology / Introduction: The changing socio-economic landscape in Africa has brought with it unique health challenges previously uncommon in people of African ancestry. Noncommunicable diseases such as coronary artery disease and stroke have emerged as pressing public health concern highlighting the need to find more on-target diagnostic tools as well as therapeutic interventions. Although ambulatory blood pressure (AMBP) has in many studies conducted in the western world proved to be an independent predictor of carotid intima-media thickness (C-IMT), such results cannot outright be imputed to people of African ancestry living in Africa. That is because people of African ancestry living in Africa are not only of a different ethnicity but are still in the early phases of an epidemiological transition while people in the western countries who are mostly Caucasians, are believed to be in the middle to late phases of an epidemiological transition. Methods: The relationship between the intima-media thickness of the common carotid artery (SonoCalcTM IMT version 3.4) and AMBP (Space labs model 90207) was determined in 320 randomly selected participants of African descent living in an urban developing community in South Africa. Relationships were determined after adjustment for (clinic blood pressure) BPc, age, gender, alcohol and tobacco use, the presence or absence of diabetes mellitus or inappropriate blood glucose control measured by glycated hemoglobin (ghb), antihypertensive therapy and menopausal status. III Results: Mean age for the study population was 43.7± 16.0 years. Both BPc and AMBP parameters were strongly associated with C-IMT (p<0.001) in univariate analysis. In multivariate analysis with BPc. and AMBP entered into separate models and after adjusting for cofounders, BPc. and AMBP maintained significant associations with CIMT. [BPc (partial r=0.0648, p< 0.1612), systolic blood pressure 24 (SBP24) (partial r= 0.236, p< 0.001), systolic blood pressure day (SBPd) (partial r= 0.302, p<0.05), systolic blood pressure night (SBPn) (partial r= 0.0983, p<0.05)]. When adjustments were made with BPc. and SBP24 entered into the same model, BPc lost its association with C-IMT, [SBP24 (partial r=0.236, p<0.001) SBPd (partial r=0.149, p<0.05), SBPn (partial r=0.172, p<0.05)]. Importantly the relationship between SBP24 and C-IMT persisted independent of body mass index (BMI), BPc and age. SBP24 had the highest significant association with C-IMT. Conclusion: SBP24 independently predicts C-IMT even in a model that includes conventional systolic blood pressure (SBPc) leading to the conclusion that AMBP is a more effective tool at diagnosing C-IMT alterations while BPcdoes not have an independent relationship C-IMT.

The thesis deals with the presentation of an overview of the methods used for leak detection set by technical standards. Following the analysis of the pressure records from the pipeline, a new method is proposed, which is based on existing methods and uses the determination of the direction of arrival of the wave directly at the measurement station. The proposed concept was subsequently developed in Matlab, where the ability to detect was also verified. The whole algorithm was then implemented in programmable logic controllers and a suitable communication between them was designed. The entire solution was then tested in terms of functionality.

Yes / Ambulatory and/or home monitoring are recommended in the UK and North America for the diagnosis of hypertension but little is known about acceptability. To determine the acceptability of different methods of measuring blood pressure to people from different ethnic minority groups. Design and setting : Cross sectional study with focus groups in primary care. Methods: People with and without hypertension of different ethnicities were assessed for acceptability of clinic, home and ambulatory blood pressure measurement using completion rate, questionnaire and focus groups. Results: 770 participants were included comprising white British (n=300), South Asian (n=241) and African Caribbean (n=229). White British participants had significantly higher successful completion rates across all monitoring modalities compared to the other ethnic groups, especially for ambulatory monitoring: white British (277 completed, 92%[89-95%]) vs South Asian (171, 71%[65-76%], p<0.001 and African Caribbean (188, 82%[77-87%], p<0.001) respectively. There were significantly lower acceptability scores for minority ethnic participants across all monitoring methods compared to white British. Focus group results highlighted self-monitoring as most acceptable and ambulatory monitoring least without consistent differences by ethnicity. Clinic monitoring was seen as inconvenient and anxiety provoking but with the advantage of immediate professional input. Conclusions: Reduced acceptability and completion rates amongst minority ethnic groups raise important questions for the implementation and interpretation of blood pressure monitoring in general and ambulatory monitoring in particular. Selection of method for blood pressure monitoring should take into account clinical need and patient preference as well as consideration of potential cultural barriers to monitoring. / NIHR
