Enhancing medical radiation science education through a design science research methodology

Recently, there has been a call for research-informed and research-developed practice in health sciences education. This prompts the consideration of alternative suitable research approaches that could be used to enhance health sciences education practice, including medical radiation sciences education (MRSE) practice. In this discussion paper, the authors uphold design science research (DSR) methodology as a suitable research approach to enhance MRSE practice and research. An overview of the DSR methodology and an example of a project that used DSR methodology are presented to demonstrate the application of this methodology in MRSE practice and research. The paper concludes that the use of DSR methodology could be instrumental in addressing practice related challenges while developing a theoretical contribution to the discipline.     

Realizing or Relinquishing Rights? Homeless Youth,Their Life on the Streets and Their Knowledge and Experience of Health and Social Services in Hillbrow,South Africa

Poverty and youth unemployment are critical issues in South Africa with homeless persons begging at traffic light intersections in all major cities. Support services represent one way of empowering homeless youth. The study therefore examined the experiences of 10 homeless young adult males in Hillbrow, Johannesburg and whether they were aware of local health and social services. Qualitative interviews revealed that participants experienced poor health, addiction, physical violence, psychological trauma, and public hostility. Despite limited education, they were aware of and utilized local health and social services. Findings are discussed in terms of their implications for social work.     

Role of CaMKII in the regulation of fatty acids and lipid metabolism

Background & aimsPrevious studies have reported the beneficial roles of the activation of calmodulin-dependent protein kinase (CaMK)II to many cellular functions associated with human health. This review aims at discussing its activation by exercise as well as its roles in the regulation of unsaturated, saturated, omega 3 fatty acids, and lipid metabolism.MethodsA wide literature search was conducted using online database such as ‘PubMed’, ‘Google Scholar’, ‘Researcher’, ‘Scopus’ and the website of World Health Organization (WHO) as well as Control Disease and Prevention (CDC). The criteria for the search were mainly lipid and fatty acid metabolism, diabetes, and metabolic syndrome (MetS). A total of ninety-seven articles were included in the review.ResultsCalmodulin-dependent protein kinase activation by exercise is helpful in controlling membrane lipids related with type 2 diabetes and obesity. CaMKII regulates many health beneficial cellular functions in individuals who exercise compared with those who do not exercise. Regulation of lipid metabolism and fatty acids are crucial in the improvement of metabolic syndrome.ConclusionsApproaches that involve CaMKII could be a new avenue for designing novel and effective therapeutic modalities in the treatment or better management of metabolic diseases such as type 2 diabetes and obesity.

Lifetime occurrence of sexually transmitted infection (STI) and substance use risk among prerelease South African prison inmates

The current study examined self-reported history of STI and substance use risk behaviors in a sample of South African prison inmates. Participants were 344 inmates from four prisons in the provinces of KwaZulu-Natal and Mpumalanga. Significance tests were conducted using univariate logistic regressions to examine the independent associations of Lifetime occurrence of a Sexual Transmitted Infection and dichotomized correlates of substance use risk behavior. Findings showed that inmates in Mpumalanga (OR 1.43; 95% CI 0.90, 2.23) had a greater risk for STIs than inmates in KwaZulu-Natal (KZN) (OR 1.11; 95% CI 0.88, 1.37). Moreover, past experience using injection drugs (OR 2.34; 95% CI 0.62, 8.88), experience of needle sharing (OR 2.13; 95% CI 0.55, 8.27), and drug/alcohol use leading to problems at school or work were the strongest indicators for inmates having a lifetime STI.     

Barriers to the management of children under five exposed to HIV in the rural areas of South Africa

BackgroundSouth Africa has made enormous progress in reducing mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV), however, MTCT and AIDS related death persist among children particularly in the rural areas. Lack of adherence to health policies and guidelines implementation remain one of the contributory factors to poor management of HIV-exposed children. Hence, the need to deeply explore the complexity of the problems and understand the barriers to the management of HIV exposed children in the rural areas.ObjectivesTo explore and synthesise the barriers to the management of children under 5 years old exposed to HIV in rural areas in South Africa.MethodAn integrative literature review was conducted. An electronic search was conducted on several databases. The researchers applied the Boolean ‘ AND’/‘OR’ in combination with phrases such as ‘HIV infection*’, ‘HIV transmission’, ‘HIV-exposed infant*, child*, and neonate*’ and ‘South Africa*’. Included studies were limited to South Africa, and articles were written in English and published in peer-reviewed journals from 2005 to 2018. Both qualitative and quantitative studies between 2005 and 2018 were utilised.ResultsThe findings highlighted that healthcare institution-related barriers, healthcare provider-related barriers, patient-related barriers and Socio-economic-related barriers were the significant barriers to the management of HIV-exposed children in the rural areas.ConclusionContinuous engagement with all relevant stakeholders should remain a priority in protecting HIV-exposed children. It is evident that there exist gaps in the current implementation of prevention of mother-to-child transmission (PMTCT), especially in rural areas. Therefore, intervention strategies that could improve implementation of PMTCT policy guidelines for HIV-exposed children in rural areas are needed.     

The psychosocial determinants of the intention to reduce the number of sexual partners among recent traditionally initiated and circumcized men in the Eastern Cape Province, South Africa

This study focuses on the factors associated with the intention to reduce the number of sexual partners. An individual face-to-face interview was used to collect data amongst 2337 traditionally initiated and circumcized men in the rural areas of Eastern Cape Province, South Africa. About 55.5% reported having a main sexual partner and of those 41.4% indicated having other sexual partners. The strongest association with intention was found for self-efficacy towards having one sexual partner, which accounted for almost 49% of the variance. These findings provide specific information for the development of a focused cultural sensitive STI/HIV prevention programme in sexually active young men, which can be integrated into the initiation and health education practices.     

Association between type of birth attendants and neonatal mortality: Evidence from a National survey

BackgroundAlthough Lesotho has one of the highest childhood mortality levels in Southern Africa, there has been limited research on the link between type of birth attendant and neonatal mortality in Lesotho. This study examined the relationship between type of birth attendant and neonatal mortality while controlling for socio-demographic characteristics of mothers in LesothoMethodsThe study used data from the children''s file of 2014 Lesotho Demographic and Health Survey data. Kaplan-Meier method was used to estimate neonatal mortality rate and Cox proportional hazard regression model was used to assess the association between type of birth attendant and neonatal mortality.ResultsResult shows that 5.3% of all births attended to by non-SBAs resulted into neonatal mortality compared to 2.8% of those attended to by SBA. Result further shows that regardless of socio-demographic characteristics, the risks of neonatal mortality were significantly higher with non-SBAs compared to SBA in Lesotho (HR: 2.00, CI: 1.31–3.06).ConclusionThe risk of neonatal mortality is two times higher among children delivered by Non-SBA. Scale-up in access and uptake of SBA is recommended in Lesotho. Thus, Policy on scale-up access to SBA at delivery at no costs need to be put in place.
