The knowledge of nurses on multidrug resistant tuberculosis at primary health care facilities in the Nelson Mandela Metropolitan

Decentralisation of the multidrug resistant tuberculosis (MDR TB) programme to primary health care (PHC) facilities in the Nelson Mandela Metropolitan was implemented in order to improve the effectiveness of MDR TB services. This study explored the knowledge gaps of nurses at PHC facilities as regards MDR TB. A quantitative, cross-sectional descriptive study was conducted; data was collected using a structured questionnaire. Non-probability sampling was applied in this study. A convenient sampling technique was used and 25 of the 42 facilities were selected. Thirty-two respondents completed the questionnaire with a response rate of 64%. Descriptive statistics were used to describe the data. Only 38% of the nurses had been trained on MDR TB. Overall scores were high with a mean knowledge score of 61%. However there were knowledge gaps regarding side effects of MDR TB medication. This study revealed gaps in knowledge of certain areas of MDR TB managementHealth StudiesM.A. (Public Health

Implementation of the dual therapy prevention of mother-to-child transmission protocol

Antiretroviral drugs taken during pregnancy, reduce the rates of mother-to-child transmission from 35 percent to as low as 1 to 2 percent (UNAIDS, 2009). In 2002, the Prevention of Mother-to-Child Transmission (PMTCT) programme was implemented in South Africa. Studies on the implementation of the PMTCT programme have shown that understaffed and under-developed health care facilities were key barriers to the provision of PMTCT services (Health Systems Trust, 2002: 6; Skinner et al., 2003). The aim of this study was to assess the challenges experienced by health care workers working in public sector facilities in the Nelson Mandela Metropole after implementation of the dual therapy PMTCT programme. Four areas were investigated: Infrastructure; Drug Supply Management; Clinic Procedures and Staffing. A quantitative descriptive study was conducted in August 2009 at nine public health care facilities in the Nelson Mandela Metropole, South Africa. Questionnaires were issued to 81 nurses and 41 pharmacy personnel (pharmacists and pharmacist assistants). Checklist audit forms were issued to the Facility Manager of each facility and completed with the researcher. The key findings for Infrastructure were lack of space at patient waiting rooms (9; 100 percent n=9), counselling area (5; 55.5 percent; n=9), nurse consultation rooms (6; 66.6 percent; n=9), storage areas (5; 55.5 percent; n=9) and filing areas (7; 77.7 percent; n=9). The key findings for Drug Supply Management were none of the dispensaries (0 percent; n=10) were fully compliant with Good Pharmacy Practice, pharmacy personnel indicated that there were no stock cards for medication (13; 31.7 percent; n=41); there was less than two weeks supply of buffer stock kept for zidovudine and nevirapine (13; 35.1percent; n=37) and medication orders were placed without any reference to minimum and maximum levels of medication (15; 36.5 percent; n=41) . The key findings for Clinic Procedures were only two facilities followed up on patients that had missed appointments (22.2 percent; n=9) and four facilities (44.4 percent; n=9) had a tracking system for patients that had defaulted. Of the nine facilities only three (33.3 percent; n=9) updated patient demographic details regularly. The key findings for Staffing were a shortage of doctors, nurses, counsellors and pharmacists at the facilities. One of the major challenges identified was the lack of training offered on new PMTCT protocols with 56.2 percent (45; n=80) of the nurses stating that no training was provided on the dual PMTCT protocol. Only 54.3 percent (44; n=81) of nurses stated that they knew the criteria to start the mother on dual PMTCT therapy. In conclusion there is an urgent need for barriers such as lack of staff, lack of space, lack of training on PMTCT and standard procedures for follow up of patients to be addressed in order to ensure the successful scaling up of PMTCT

The impact of foreign exchange controls on economic performance of emerging economies and South Africa in particular

This study sets out to investigate the impact of foreign exchange controls on economic performance of emerging economies and South Africa in particular. Amidst South Africa’s newly established stable political environment and its reintroduction to the global economy, a fierce debate exists on whether some measure of exchange controls are necessary or whether they should be abolished altogether. The debate also extends to the nature of the economic liberalisation process in the removal of exchange controls, either in an instantaneous “big bang” approach or in a gradual manner. The research describes arguments for both the support of exchange controls and their abolition. This includes a description of the path South Africa has adopted and an assessment of the merits of exchange controls. Experience from other emerging economies is investigated and correlated with the South African experience. Results indicated that a gradual approach in the relaxation of exchange controls is recommended and that domestic monetary and fiscal policy and trade reforms first before liberating the capital account. It was found that the intensive use of exchange controls as a means of capital account restriction appears to hinder good economic performance; instead it is recommended to create and maintain an institutional environment in which the investment process can occur and where policy-makers can stimulate investment activity with a consequential elimination of capital flight.Dissertation (MBA)--University of Pretoria, 2010.Gordon Institute of Business Science (GIBS)unrestricte

The outcome of preterm births in pregnant women with hypertensive disorders: an observational study

Background: Hypertensive conditions occurring during pregnancy are linked to heightened chances of severe consequences, including preterm birth, intrauterine growth restriction, perinatal mortality and morbidity, acute kidney failure, sudden liver malfunction, excessive postpartum bleeding, HELLP Syndrome, disseminated intravascular coagulation, and seizures. Methods: A prospective hospital-based study was conducted in a tertiary care hospital of eastern Uttar Pradesh, over the period of one year. The total sample size calculated was 235. Data was collected using the structured questionnaire. This study recruited the hypertensive pregnant women with a blood pressure reading of 140/90 mmHg or higher, irrespective of the timing of the blood pressure elevation, who visited the hospital for delivery over the course of one year. Various maternal variables were examined, including age, gestational age, number of previous deliveries, the status of the mother's blood pressure, and the type of delivery. Results: In the present study, the births revealed the following distribution among different hypertensive disorders: chronic hypertension preterm: 100.0% 06 vs. term: 0% 0, eclampsia, preterm: 60.4% 64 vs. term: 39.6% 42, mild preeclampsia, preterm: 55.3% vs. term: 44.7%, severe preeclampsia, preterm: 48.5% vs. term: 51.5%, and gestational hypertension, preterm: 23.5% vs. term: 76.5%. Conclusions: Based on the findings of this study, it was determined that hypertensive disorders play a pivotal role in influencing both the frequency of preterm delivery and the associated complications in infants resulting from premature birth

Fulminant amoebic colitis in the era of computed tomography scan: A case report and review of the literature

Amoebic colitis, caused by ingestion of water or food contaminated with the protozoan Entamoeba histolytica, can progress to a fulminant colitis. Computed tomography (CT) findings reported in the literature on this type of colitis are sparse. We present a 59-year-old male patient with a one-week history of progressive abdominal pain, abdominal distension and associated watery and bloody diarrhoea. A CT scan revealed deep ulcerations with submucosal and intramural tracking of contrast. Colonoscopy and biopsy confirmed a diagnosis of Amoebic colitis. The patient required a laparotomy and demised. Deep ulcerations with submucosal and intramural tracking of contrast on CT are diagnostic of fulminant amoebic colitis. Although not demonstrated at CT in this case, discontinuous bowel necrosis, omental wrapping (seen at laparotomy in our case) and neovascularisation of the bowel wall may be other features to look out for

Microstructure and tribological response of selective laser melted AISI 316L stainless steel : the role of severe surface deformation

This study investigates the effect of surface mechanical attrition treatment (SMAT) (a severe surface-deformation process) on microstructure and tribological behavior of AISI 316L steel samples manufactured using the selective laser melting (SLM) technique. The specimens are built in different directions (0°, 45°, and 90°). The microstructure of annealed SLM samples shows the non-uniform distribution and random orientation of grains. It contains high-angle grain boundaries and a high density of dislocations. The average grain size is about 63, 51, and 41 μm for 0°, 45°, and 90° build direction, respectively. SMAT is beneficial for SLM steel to reduce surface roughness (by ~ 87%) and eliminate internal porosity. The deformed layer of SLM steel shows a highly dense network of slip bands, distortion of grains, and hardness gradient (up to the depth of about 600 μm). Increase in surface hardness due to SMAT is maximum (~ 54%) for the sample having 90° build direction. Typical observation of deformation-induced martensite is absent for the SMAT-processed SLM steel. Under the higher load (especially, 20 N), the tribological response of sample manufactured in the 90° direction is superior amongst the non-treated samples. Severe surface deformation enhances the wear resistance and reduces the COF of SLM steel

Quality of Life in Chronic Pancreatitis is Determined by Constant Pain, Disability/Unemployment, Current Smoking, and Associated Co-Morbidities

OBJECTIVES: Chronic pancreatitis (CP) has a profound independent effect on quality of life (QOL). Our aim was to identify factors that impact the QOL in CP patients. METHODS: We used data on 1,024 CP patients enrolled in the three NAPS2 studies. Information on demographics, risk factors, co-morbidities, disease phenotype, and treatments was obtained from responses to structured questionnaires. Physical and mental component summary (PCS and MCS, respectively) scores generated using responses to the Short Form-12 (SF-12) survey were used to assess QOL at enrollment. Multivariable linear regression models determined independent predictors of QOL. RESULTS: Mean PCS and MCS scores were 36.7+/-11.7 and 42.4+/-12.2, respectively. Significant (P \u3c 0.05) negative impact on PCS scores in multivariable analyses was noted owing to constant mild-moderate pain with episodes of severe pain or constant severe pain (10 points), constant mild-moderate pain (5.2), pain-related disability/unemployment (5.1), current smoking (2.9 points), and medical co-morbidities. Significant (P \u3c 0.05) negative impact on MCS scores was related to constant pain irrespective of severity (6.8-6.9 points), current smoking (3.9 points), and pain-related disability/unemployment (2.4 points). In women, disability/unemployment resulted in an additional 3.7 point reduction in MCS score. Final multivariable models explained 27% and 18% of the variance in PCS and MCS scores, respectively. Etiology, disease duration, pancreatic morphology, diabetes, exocrine insufficiency, and prior endotherapy/pancreatic surgery had no significant independent effect on QOL. CONCLUSIONS: Constant pain, pain-related disability/unemployment, current smoking, and concurrent co-morbidities significantly affect the QOL in CP. Further research is needed to identify factors impacting QOL not explained by our analyses

Pain Management in Acute Pancreatitis: A Systematic Review and Meta-Analysis of Randomised Controlled Trials

Background: Pain management is an important priority in the treatment of acute pancreatitis (AP). Current evidence and guideline recommendations are inconsistent on the most effective analgesic protocol. This systematic review and meta-analysis of randomised controlled trials (RCTs) aimed to compare the safety and efficacy of analgesics for pain relief in AP. Methods: A literature search was performed to identify all RCTs assessing analgesics in patients with AP. The primary outcome was the number of participants who needed rescue analgesia. Study quality was assessed using Jadad score. Pooled odds ratios (ORs) or weighted mean differences (WMDs) with 95% confidence intervals (CI) were analysed using a random-effects model. Results: Twelve studies comprising 699 patients with AP (83% mild AP) were analysed. The tested analgesics significantly decreased the need for rescue analgesia (3 studies, OR.36, 95% CI 0.21 to 0.60) vs. placebo or conventional treatment. The analgesics also improved the pain score [Visual Analogue Scale (Δ-VAS)] at 24 h (WMD 18.46, 0.84 to 36.07) and by the 3rd to 7th days (WMD 11.57, 0.87 to 22.28). Opioids vs. non-opioids were associated with a decrease in the need for rescue analgesia (6 studies, OR 0.25, 95% CI 0.07 to 0.86, p = 0.03) but without significance in pain score. In subgroup analyses, opioids were similar to non-steroidal anti-inflammatory drugs (NSAIDs) regarding the primary outcome (4 studies, OR 0.56, 95% CI 0.24 to 1.32, p = 0.18). There were no significant differences in other clinical outcomes and rate of adverse events. Other studies, comparing epidural anaesthesia vs. patient-controlled analgesia and opioid (buprenorphine) vs. opioid (pethidine) did not show significant difference in primary outcome. Study quality issues significantly contributed to overall study heterogeneity. Conclusions: NSAIDs and opioids are equally effective in decreasing the need for rescue analgesia in patients with mild AP. The relative paucity of trials and high-quality data in this setting is notable and the optimal analgesic strategy for patients with moderately severe and severe AP still requires to be determined
