ABSTRACT

The prevalence of cardiovascular disease (CVD) has increased in South Africa, emphasizing the importance of prevention strategies. This study used echocardiography to investigate the impact of Rooibos on cardiovascular function in those at risk of CVD. This research aims to contribute to understanding its effects on reducing cardiovascular risk factors. The study design involved a 12-week randomized, parallel, double-blinded, placebo-controlled dietary intervention trial using capsules containing standardized water-soluble extracts of green and traditional fermented Rooibos alongside a placebo control. Echocardiography was incorporated as a diagnostic imaging tool to assess cardiac function in the participant cohort. Aorta (AO) dimensions showed no significant change in any intervention group. Left atrium (LA) reduced in size from 3.832 ± 0.071 cm to 3.675 ± 0.067 cm (P = 0.01). There was no significant change in LA/AO ratio in any intervention group. Interventricular septum diameter in the placebo group decreased from 1.334 ± 0.030 cm to 1.250 ± 0.025 cm (P = 0.002), with no significance in fermented Rooibos, while green Rooibos resulted in a decrease from 1.282 ± 0.036 cm to 1.186 ± 0.029 cm (P = 0.002). Left ventricle posterior wall (LVPW) showed no significant changes in any of the intervention group. The left ventricle mass in the placebo and green Rooibos groups demonstrated no significance changes, while fermented Rooibos caused a decrease from 204.102 ± 7.102 g to 191.394 ± 6.707 g (P = 0.015). The phytochemical bioactive components, such as the polyphenolic antioxidants present in green and fermented Rooibos, improved cardiovascular function. This study confirms the effectiveness of echocardiography as imaging tool for assessing cardiac function in this particular population. Regular Rooibos consumption may offer promising therapeutic benefits for preventing and managing CVD risk.

ABSTRACT

Objective: To identify and appraise mobile-based application (mAPP) interventions that have been used to support cancer control and care in low- and middle-income countries (LMICs). Methods: Four electronic databases were systematically searched for studies that reported primary research findings related to mAPP interventions applied in oncology settings in LMICs. A narrative synthesis was performed using the Mhealth Index and Navigation Database as an analytical framework. Results: Twenty studies reporting 18 cancer control and care mAPPs were included in this review. Among these mAPPs, ten focused on prevention, screening and early detection of cancer, five provided information to optimise supportive and palliative care, two provided support to assist treatment-shared decision-making and one covered information for follow-up and survivorship care. Conclusion: Cancer mAPP interventions are gradually gaining attention in LMICs as they provide unique resources for empowering and strengthening the role of people with cancer in their own care. To enhance cancer control, a focus on prevention and early detection is important; however, more mAPP interventions related to cancer treatment, follow-up and survivorship are also needed to enable more cost-effective cancer care.

ABSTRACT

Chronic exposure to stress throughout the lifespan has been the focus of many studies on Alzheimer's disease (AD) because of the similarities between the biological mechanisms involved in chronic stress and the pathophysiology of AD. In fact, the earliest abnormality associated with the disease is the presence of phosphorylated tau protein in locus coeruleus neurons, a brain structure highly responsive to stress and perceived threat. Here, we introduce allostatic load as a useful concept for understanding many of the complex, interacting neuropathological changes involved in the AD degenerative process. In response to chronic stress, aberrant tau proteins that begin to accumulate within the locus coeruleus decades prior to symptom onset appear to represent a primary pathological event in the AD cascade, triggering a wide range of interacting brain changes involving neuronal excitotoxicity, endocrine alterations, inflammation, oxidative stress, and amyloid plaque exacerbation. While it is acknowledged that stress will not necessarily be the major precipitating factor in all cases, early tau-induced changes within the locus coeruleus-norepinephrine pathway suggests that a therapeutic window might exist for preventative measures aimed at managing stress and restoring balance within the HPA axis.

ABSTRACT

Background: Literature indicates the need to prepare health professionals who are clinically competent and socially conscious. Engagement in community projects, as an extension of workplace learning, can build professional competence and social awareness. Aim: To interrogate one such engagement; an emergency first aid responder training course was orchestrated by undergraduate students studying Emergency Medical Care. Setting: The intervention was offered in response to a community need emerging from the research project being conducted in a community in the Western Cape, South Africa. Method: Qualitative data were gathered as narrative texts from participants in the intervention and student reports about their learning experience. The data were interrogated through the application of reflexive thematic analysis and the theoretical lens of asymmetrical reciprocity. Findings: The three themes that emerged were: from research to a student led intervention, deep authentic learning, and learning as a shared experience. Benefit accrued to the students and community through a partnership of asymmetrical participants. The community offered a learning experience while students offered desired skills acquisition to community members. Conclusion: Through this interaction, students learnt respect for local knowledges, and gained enhanced social awareness, in a transdisciplinary partnership, that aimed to create a learning environment where academics, students, and community members are partners in a project delivered with a core value of social justice. Contribution: A pedagogy of partnership describes an education model arising from community-based research that enabled a social programme intervention as a relevant learning project for health science students.

ABSTRACT

Decades of research provide evidence that certain phytochemicals in tea (Camellia sinensis) and other herbal beverages are protective against the development of sporadic types of dementia in later life. Since tea drinking is an economical and widely adopted social-cultural practice across all age groups, it is an ideal product to target in designing low-cost dietary interventions for Alzheimer's Disease (AD), the most prevalent form of dementia. In this review, we focus on the protective roles of tea-derived polyphenols and other phytochemicals on mood, the stress response, attention, and sleep, in keeping with the perspective that many early neuropathological events in AD may stem, in part, from allostatic overload. This approach aligns with the perspective that many forms of dementia, including AD, begin to take root in the brain decades prior to symptom onset, underscoring the need for early uptake of accessible and viable lifestyle interventions. The findings reviewed here suggest that consuming green and oolong tea can improve mood and reduce overall stress. However, given the caffeine content in tea and its association with stress reactivity, the effects of daily whole tea consumption on the emotional state are likely dose-dependent with an inverted-U relationship to wellbeing. Plant-based beverages that are to be consumed in high daily quantities for health purposes and which are naturally free of caffeine, such as Rooibos, may be more appropriate as a dietary supplement for managing emotional regulation over the lifetime.

ABSTRACT

Background: Lipid metabolism may impact disability in people with multiple sclerosis (pwMS). Methods: Fifty-one pwMS entered an ultrasound and MRI study, of whom 19 had followed a pathology-supported genetic testing program for more than 10 years (pwMS-ON). Genetic variation, blood biochemistry, vascular blood flow velocities, diet and exercise were investigated. Results: pwMS-ON had significantly lower (p < 0.01) disability (Expanded Disability Status Scale) than pwMS not on the program (1.91 ± 0.75 vs 3.87 ± 2.32). A genetic variant in the lipid transporter FABP2 gene (rs1799883; 2445G>A, A54T) was significantly associated (p < 0.01) with disability in pwMS not on the program, but not in pwMS-ON (p = 0.88). Vascular blood flow velocities were lower in the presence of the A-allele. Conclusion: Pathology-supported genetic testing may provide guidance for lifestyle interventions with a significant impact on improved disability in pwMS.


This study investigated the role of a genetic variant that increases saturated fat absorption and may make people with multiple sclerosis (MS) more susceptible to disability progression. Of 51 people with MS, 19 had followed a program which includes normalization of blood test results and daily intake of unsaturated fatty acids for more than 10 years, while the others had not. The latter group had significantly greater disability than the people who had followed the program, suggesting that the unsaturated fatty acids modulated the effect of the genetic variant. Six MS cases are presented as examples, including a marathon athlete (Case 1) and a patient who showed a dramatic decrease in disability from being wheelchair-bound for 15 years to walking freely (Case 2).

ABSTRACT

A systematic literature review was carried out to explore articles that reported the use of radiation dose management systems (RDMSs) in computed tomography (CT). The preferred reporting items for systematic review and meta-analysis flow chart were used to screen articles in PubMed, EBSCOhost, Web of Science, SCOPUS and Cochrane Library. A total of 1041 articles were retrieved and screened. After evaluation against criteria, 38 articles were selected and synthesised narratively. The results revealed that several RDMSs have been used in CT. The review also indicated that the use of RDMSs has promoted the implementation of diagnostic reference levels for dose optimisation. A RDMS, such as DoseWatch, is associated with compatibility challenges and failure in data transmission, while manual RDMSs are cumbersome and prone to data entry errors. Thus, a robust automated RDMS that is compatible with the different CT systems would provide efficient CT dose management.

ABSTRACT

Global health inequities have created an urgency for health professions education to transition towards responsive and contextually relevant curricula. Such transformation and renewal processes hold significant implications for those educators responsible for implementing the curriculum. Currently little is known about how health professions educators across disciplines understand a responsive curriculum and how this understanding might influence their practice. We looked at curricula that aim to deliver future health care professionals who are not only clinically competent but also critically conscious of the contexts in which they serve and the health care systems within which they practice. We conducted a qualitative study across six institutions in South Africa, using focus group discussions and in-depth individual interviews to explore (i) how do health professions educators understand the principles that underpin their health professions education curriculum; and (ii) how do these understandings of health professions educators shape their teaching practices? The transcripts were analysed thematically following multiple iterations of critical engagement to identify patterns of meaning across the entire dataset. The results reflected a range of understandings related to knowing, doing, and being and becoming; and a range of teaching practices that are explicit, intentionally designed, take learning to the community, embrace a holistic approach, encourage safe dialogic encounters, and foster reflective practice through a complex manner of interacting. This study contributes to the literature on health professions education as a force for social justice. It highlights the implications of transformative curriculum renewal and offers insights on how health professions educators embrace notions of social responsiveness and health equity to engage with these underlying principles within their teaching.

ABSTRACT

BACKGROUND: Although multiple sclerosis (MS) is an immune-related disorder, pharmaceutical interventions targeting the immune system do not stop or reverse disability progression; the major challenge for this condition. Studies show that disability progression in MS is associated with vascular comorbidity and brain volume loss, indicating that a multi-targeted approach is required to prevent debilitation. The aim of the present study was to examine the associations between vascular ultrasound, disability, biochemistry and lifestyle data in people with MS (pwMS). METHODS: Extracranial vascular ultrasound was performed on 51 pwMS and 25 age-matched controls. Sonographic interrogation determined carotid intima-media thickness (cIMT) and abnormal blood flow patterns. Disability was assessed using the Expanded Disability Status Scale (EDSS). Biochemical and lifestyle data were obtained for all participants. RESULTS: The EDSS had a highly significant positive association with the cIMT of the right (r = 0.63; p = 0.001) and left (r = 0.49; p = 0.001) common carotid arteries and negative associations with the peak systolic blood flow velocity of the right vertebral artery (r = -0.42; p = 0.01) as well as end-diastolic velocity of the left internal carotid artery (r = -0.47; p = 0.01). These associations were significantly influenced by biochemical and lifestyle factors. Both cIMT and age showed significant associations with the EDSS. When cIMT was adjusted for age in a regression analysis, the association between the EDSS and the cIMT remained significant (p < 0.01), while the age association was reduced to being significant only at 10% (p = 0.06). There was no association between the use of MS medication and the EDSS (p = 0.56). CONCLUSION: PwMS who had increased cIMT, a surrogate marker for atherosclerosis, and reduced carotid artery blood flow velocities were at risk for greater disability over and above the effect of aging. These findings provide important information for disease management and disability prevention in pwMS. Modification of diet and lifestyle may promote the unhindered flow of essential nutritional factors into the brain in pwMS.

ABSTRACT

INTRODUCTION: Radiology is a technical service that provides medical imaging for all sectors of healthcare. Hospital-acquired infections (HAIs) is a major challenge in radiology and this is exacerbated in contexts where the healthcare system is unable to provide adequate funding and attention to effective infection control measures. The objectives of this study were to audit current cleaning procedures through the observation of practices in a radiology department, and to determine the types and numbers of nosocomial pathogens present on selected radiology imaging equipment and accessories before and after decontamination. METHODOLOGY: In phase one we observed seven radiographers to audit cleaning procedures and practices. In phase two we collected swab samples from selected radiology imaging equipment and accessories and then cultured them for identification of microbes. RESULTS: It was observed that radiographers partially practiced infection control measures. This was due to the absence of documented protocol for infection control procedures. Our results indicated that all the selected equipment and accessories were contaminated with microorganisms pre- and post-cleaning. The identified microbes were Staphylococcus aureus, Coagulase negative Staphylococci (CoNS), Bacillus species (spp.), Shigella spp., Shigella sonnei., Klebsiella spp., Salmonella paratyphi A (S. paratyphi A), Salmonella typhi (S. typhi), Providencia rettgeri, Enterobacter spp. and Citrobacter spp. and Methicillin resistant strains of Staphylococcus aureus (MRSA). CONCLUSIONS: The research concluded that the recommended cleaning agents did not effectively reduce the number of microorganisms making the selected equipment and accessories fomites for nosocomial pathogens.

ABSTRACT

BACKGROUND: Postmortem computed tomography (CT) and magnetic resonance imaging have been gradually introduced to forensic pathology centres over the past two decades, with varying results in comparison to autopsy. OBJECTIVE: The purpose of this study was to determine the accuracy of postmortem CT in determining a cause of death in children who died of unnatural causes. MATERIALS AND METHODS: This was a prospective recruitment of 30 children (< 18 years) who underwent postmortem CT and a forensic autopsy. A cause of death was independently assigned by two experienced paediatric radiologists and compared to that of the forensic autopsy. RESULTS: A correct cause of death was assigned by reviewers 1 and 2 in 70% (n = 21/30) and 67% (n = 20/30) of cases, respectively. For gunshot injuries and blunt force head injuries, there was 91% (n = 10/11) and 100% (n = 6/6) agreement between forensic autopsy and both reviewers, respectively. No cause of death could be assigned by reviewers 1 and 2 in 27% (n = 8) and 30% (n = 9) of cases, respectively. An incorrect cause of death was assigned by both reviewers in one case (3%). The Cohen Kappa level of agreement between the forensic autopsy and reviewers 1 and 2 was k = 0.624 (95% confidence interval [CI]: 0.45-0.80, P = 0) and k = 0.582 (95% CI 0.41-0.76, P = 0), respectively. There was near perfect agreement between reviewers 1 and 2 (k = 0.905) (95% CI 0.78-1.00, P = 0). CONCLUSION: Postmortem CT has good diagnostic accuracy for identifying a cause of death related to trauma, but it has poor accuracy for children dying from causes not associated with apparent physical injury.

ABSTRACT

In this Review (Part I), we investigate the scientific evidence that multiple sclerosis (MS) is caused by the death of oligodendrocytes, the cells that synthesize myelin, due to a lack of biochemical and nutritional factors involved in mitochondrial energy production in these cells. In MS, damage to the myelin sheaths surrounding nerve axons causes disruption of signal transmission from the brain to peripheral organs, which may lead to disability. However, the extent of disability is not deterred by the use of MS medication, which is based on the autoimmune hypothesis of MS. Rather, disability is associated with the loss of brain volume, which is related to the loss of grey and white matter. A pathology-supported genetic testing (PSGT) method, developed for personalized assessment and treatment to prevent brain volume loss and disability progression in MS is discussed. This involves identification of MS-related pathogenic pathways underpinned by genetic variation and lifestyle risk factors that may converge into biochemical abnormalities associated with adverse expanded disability status scale (EDSS) outcomes and magnetic resonance imaging (MRI) findings during patient follow-up. A Metabolic Model is presented which hypothesizes that disability may be prevented or reversed when oligodendrocytes are protected by nutritional reserve. Evidence for the validity of the Metabolic Model may be evaluated in consecutive test cases following the PSGT method. In Part II of this Review, two cases are presented that describe the PSGT procedures and the clinical outcomes of these individuals diagnosed with MS.

ABSTRACT

In Part I of this Review we evaluated the scientific evidence for a Metabolic Model of multiple sclerosis (MS). Part II outlines the implementation of an adaptive pathology-supported genetic testing (PSGT) algorithm aimed at preventing/reversing disability in two illustrative MS cases, starting with a questionnaire-based risk assessment, including family history and lifestyle factors. Measurement of iron, vitamin B12, vitamin D, cholesterol and homocysteine levels identified biochemical deficits in both cases. Case 1, after following the PSGT program for 15 years, had an expanded disability status scale (EDSS) of 2.0 (no neurological sequelae) together with preserved brain volume on magnetic resonance imaging (MRI). A novel form of iron deficiency was identified in Case 1, as biochemical testing at each hospital submission due to MS symptoms showed low serum iron, ferritin and transferrin saturation, while hematological status and erythrocyte sedimentation rate measurement of systemic inflammation remained normal. Case 2 was unable to walk unaided until her EDSS improved from 6.5 to 4.0 over 12 months after implementation of the PSGT program, with amelioration of her suboptimal biochemical markers and changes to her diet and lifestyle, allowing her to regain independence. Genotype-phenotype correlation using a pathway panel of functional single nucleotide variants (SNVs) to facilitate clinical interpretation of whole exome sequencing (WES), elucidated the underlying metabolic pathways related to the biochemical deficits. A cure for MS will remain an elusive goal if separated from nutritional support required for production and maintenance of myelin, which can only be achieved by a lifelong investment in wellness.

ABSTRACT

A powerful set of projections has constructed post-apartheid higher education in South Africa. Among these is the expectation that technikons (institutions similar to the British polytechnics) would become universities of technology, with a mission to drive the technology of national reconstruction and development. In this paper, one of the new universities of technology serves as a case study to explore organizational structure and to highlight the ethics of university management and leadership. Building a new university provides the opportunity to place ethics "upfront", rather than as an afterthought, by constructing an organizational framework that makes ethical issues integral to management and decision-making processes. In imagining the structure of a university of technology, the authors were inspired by future scripting methods developed by Bastiaan De Laat, and by Duncan Den Boer, Arie Rip and Sandra Speller. The research process firstly involved the identification of themes related to values and ethics through an analysis of the environment. These themes were incorporated into three scenarios of possible futures for this new university type. Using these scenarios, the ethical issues that emerged (according to how the university of technology might choose to organise itself), are compared with the original themes. Conclusions are then drawn with regard to management structures that are hierarchical and entrench compliance, or that are traditionally collegiate and expertise-based, or that might enable mutual appreciation and allow for leaders to emerge within any functional space at a university of technology.

ABSTRACT

PURPOSE: This study aimed to share the application, experiences, and lessons learnt regarding the value of the Mmogo-method that is a visual projective research method, in the context of exploring the experiences and coping of undergraduate diagnostic radiography students with death and dying patients in the workplace. METHODS: Verbatim data were gathered during the debriefing phase of the adapted Mmogo-method technique from the participants. In addition, the reflective memos of the independent coder and interviewer were used as data sources. RESULTS: The experiences of various stakeholders positively supported the use of the visual projective research method. The method enabled them to freely and openly verbalise their experiences of coping with death and dying in the workplace. Juxtaposing these was one experience of indifference. CONCLUSION: The Mmogo-method provides rich data and enables an ethically and methodologically rigorous opportunity to obtain new insights into sensitive topics. It is recommended for consideration when researching sensitive topics.

ABSTRACT

Multiple sclerosis (MS) is a disorder related to myelin damage, which can be investigated by neuroimaging techniques such as fractional anisotropy (FA), a measure of microstructural white matter properties. The objectives of this study were to investigate (1) the relationship between FA and disability using an extremes of outcome approach, and (2) whether blood iron parameters were associated with FA and/or disability. Patients diagnosed with MS (n = 107; 14 males and 93 females) had iron parameter tests and disability determinations using the Expanded Disability Status Scale (EDSS). FA was recorded in 48 white matter tracts in 11 of the female patients with MS and 12 female controls. RESULTS: In patients with high disability scores the mean FA was significantly lower (0.34 ± 0.067) than in the control group (0.45 ± 0.036; p = 0.04), while patients with low disability had mean FA values (0.44 ± 0.014) similar to controls (p = 0.5). Positive associations were found between FA and the iron parameters serum iron, ferritin and percentage transferrin saturation (%Tfsat) in all the white matter tracts. For % Tfsat, the associations were highly significant in 14 tracts (p < 0.01; r-values 0.74-0.84) and p < 0.001 (r = 0.83) in the superior fronto occipital fasciculus (LH). In the whole patient group a trend was found towards an inverse association between the EDSS and the %Tfsat (r = -0.26, p = 0.05) after excluding male gender and smoking as confounders, suggesting reduced disability in the presence of higher blood iron parameters. Additionally, significant inverse associations between disease duration and haemoglobin (p = 0.04) as well as %Tfsat (p = 0.02) suggested that patients with MS may experience a decrease in blood iron concentrations over time.
