When fees fall: Conceptualizing "free" higher education as a public good

This article conceptualizes “free” higher education as a public good. It draws on a qualitative study conducted between 2018‒2019, exploring academics’ understanding of the relationship between higher education and the public good, and the conditions of possibility for higher education to be and contribute to the public good. In so doing, this article argues that funding for free education is a necessary condition for higher education to be a public good that can be accessed by students from different socioeconomic backgrounds. It argues that commodification of higher education undermines the public good character of higher education, and ultimately reproduces inequalities in society, and the injustices of the past, particularly in a country like South Africa characterised by colonial and apartheid histories. It anchors this argument on an analysis of 15 in-depth one-on-one interviews with academics from historically white and historically black universities in South Africa. From this analysis emerged three main findings on the issue of higher education funding. Firstly, the view that funding for higher education is scarce due to austerity, among other things. Secondly, the notion that if higher education is a public good and for the public good, it must be funded by the state. Lastly, the argument that adopting private funding models opens higher education to commodification, elitism, and the risk of being captured and used as an instrument of advancing private goods at the expense of the public good. The implication of these findings is the notion that when fees fall, one obstacle is removed, opening access to higher education – a public good – even for the poorest of the poor

Moving from discourse to Praxis: Situating academics at the centre of decolonisation struggle:

As part of contributing to the decolonisation debate to reclaim and re-purpose the universities as public good institutions, drawing from Freire’s notion of praxis we argue that there is a need to move from theorisation of concepts or what we refer to as discourses to praxis, and academics must drive the decolonisation project. Unlike students, academics have immense power to influence choices of pedagogical approaches, processes of curriculum design, and knowledge production. Academics enjoy academic freedom. This implies that they have the freedom to teach and conduct research without external control in their area of expertise, which gives them special protection within the classroom and the parameters of their field of expert knowledge. Thus, we argue that the freedom that academics enjoy puts them in a good position to be drivers of the project of decolonising higher education. As key role players on processes of teaching and learning as well as knowledge production in higher education, they have some degree of power that they are better positioned to drive the decolonial project. They can use their roles as teachers and researchers to advance the decolonisation agenda

Starvation ketoacidosis in pregnancy presenting as euglycaemic, high anion gap metabolic acidosis: A case report highlighting the significance of early recognition and prompt intervention

Starvation ketoacidosis (SKA) constitutes an important consideration in the pregnant patient who presents with profound metabolic acidosis. Pregnancy-related changes predispose the patient to develop SKA following relatively short periods (12 - 14 hours) of ‘starvation’. Patients also typically look clinically well in relation to the significant metabolic derangements that accompany the condition. Prompt recognition and early institution of appropriate therapy is therefore extremely important in terms of optimising maternal and fetal outcome. We describe a pregnant patient with SKA who presented with profound euglycaemic ketoacidosis that resolved rapidly following the early initiation of appropriate therapy. Furthermore, appropriate therapy resulted in our patient avoiding the need for an emergency caesarean section, which is often reported in this scenario. The ensuing discussion addresses SKA in pregnancy, the unique features of our patient, and management considerations from a maternal and fetal perspective. We also discuss the various causes of ketoacidosis such as diabetic ketoacidosis (DKA), euglycaemic DKA, alcohol-induced euglycaemic ketoacidosis and SKA in pregnant patients

Cognitive deficits in people who have recovered from COVID-19.

BACKGROUND: There is growing concern about possible cognitive consequences of COVID-19, with reports of 'Long COVID' symptoms persisting into the chronic phase and case studies revealing neurological problems in severely affected patients. However, there is little information regarding the nature and broader prevalence of cognitive problems post-infection or across the full spread of disease severity. METHODS: We sought to confirm whether there was an association between cross-sectional cognitive performance data from 81,337 participants who between January and December 2020 undertook a clinically validated web-optimized assessment as part of the Great British Intelligence Test, and questionnaire items capturing self-report of suspected and confirmed COVID-19 infection and respiratory symptoms. FINDINGS: People who had recovered from COVID-19, including those no longer reporting symptoms, exhibited significant cognitive deficits versus controls when controlling for age, gender, education level, income, racial-ethnic group, pre-existing medical disorders, tiredness, depression and anxiety. The deficits were of substantial effect size for people who had been hospitalised (N = 192), but also for non-hospitalised cases who had biological confirmation of COVID-19 infection (N = 326). Analysing markers of premorbid intelligence did not support these differences being present prior to infection. Finer grained analysis of performance across sub-tests supported the hypothesis that COVID-19 has a multi-domain impact on human cognition. INTERPRETATION: Interpretation. These results accord with reports of 'Long Covid' cognitive symptoms that persist into the early-chronic phase. They should act as a clarion call for further research with longitudinal and neuroimaging cohorts to plot recovery trajectories and identify the biological basis of cognitive deficits in SARS-COV-2 survivors.

Noise-induced hearing loss and hearing conservation in the iron and steel industry in South Africa

BACKGROUND AND PURPOSE: The iron and steel industry in South Africa has been identified as one of the highest risk industries in terms of noise induced hearing loss (NIHL). The National Institute for Occupational Health was commissioned by the Department of Labour to audit the current noise exposure levels and hearing conservation practices in eight major producers of iron and steel, and to make recommendations regarding prevention strategies. METHODS: The audit was conducted in two parts: the noise exposure levels and hearing conservation practices were assessed by the occupational hygiene department. The occupational medicine department assessed the hearing conservation policies and procedures, reviewed employees’ medical records to ascertain the number of NIHL cases, and conducted verification of audiograms on a sample of employees working in noise zones. RESULTS: Area noise levels exceeding 105 dB(A) were measured in four of the eight workplaces. The estimated average annual incidence of NIHL varied from 0.7 - 8.3/1000/year. All companies did baseline, periodic and exit audiometric testing, but there were notable discrepancies between companies and verification audiograms and differences of more than 20 dB(A) were found. Although information and training on noise was reportedly done in all worksites, a high proportion of workers could not demonstrate correct fitting of hearing protection devices or recall when last they were trained. CONCLUSION: A detailed standard operating procedure should be implemented for medical surveillance for NIHL with action timelines that initiate remedial processes prior to employee developing compensable disease. Aggregated audiometric testing results should be communicated to managers and health and safety teams to provide guidance to prioritise areas for control measures. A quality assurance programme for audiometric testing must be implemented. An evaluation tool to measure the effectiveness of the noise and hearing conservation training provided to employees, including contracted employees, should be adopted.http://www.occhealth.co.zaam201

Cholinergic modulation of disorder-relevant human defensive behaviour in generalised anxiety disorder

Drugs that are clinically effective against anxiety disorders modulate the innate defensive behaviour of rodents, suggesting these illnesses reflect altered functioning in brain systems that process threat. This hypothesis is supported in humans by the discovery that the intensity of threat-avoidance behaviour is altered by the benzodiazepine anxiolytic lorazepam. However, these studies used healthy human participants, raising questions as to their validity in anxiety disorder patients, as well as their generalisability beyond GABAergic benzodiazepine drugs. BNC210 is a novel negative allosteric modulator of the alpha 7 nicotinic acetylcholine receptor and we recently used functional Magnetic Resonance Imaging to show it reduced amygdala responses to fearful faces in generalised anxiety disorder patients. Here we report the effect of BNC210 on the intensity of threat-avoidance behaviour in 21 female GAD patients from the same cohort. We used the Joystick Operated Runway Task as our behavioural measure, which is a computerised human translation of the Mouse Defense Test Battery, and the Spielberger state anxiety inventory as our measure of state affect. Using a repeated-measures, within-subjects design we assessed the effect of BNC210 at two dose levels versus placebo (300 mg and 2000 mg) upon two types of threat-avoidance behaviour (Flight Intensity and Risk Assessment Intensity). We also tested the effects of 1.5 mg of the benzodiazepine lorazepam as an active control. BNC210 significantly reduced Flight Intensity relative to placebo and the low dose of BNC210 also significantly reduced self-reported state anxiety. Risk Assessment Intensity was not significantly affected. Results show both human defensive behaviour and state anxiety are influenced by cholinergic neurotransmission and there provide converging evidence that this system has potential as a novel target for anxiolytic pharmacotherapy

An effectiveness study of an integrated, community-based package for maternal, newborn, child and HIV care in South Africa: study protocol for a randomized controlled trial

BACKGROUND: Progress towards MDG4 in South Africa will depend largely on scaling up effective prevention against mother to child transmission (PMTCT) of HIV and also addressing neonatal mortality. This imperative drives increasing focus on the neonatal period and particularly on the development and testing of appropriate models of sustainable, community-based care in South Africa in order to reach the poor. A number of key implementation gaps affecting progress have been identified. Implementation gaps for HIV prevention in neonates; implementation gaps for neonatal care especially home postnatal care; and implementation gaps for maternal mental health support. We have developed and are evaluating and costing an integrated and scaleable home visit package delivered by community health workers targeting pregnant and postnatal women and their newborns to provide essential maternal/newborn care as well as interventions for Prevention of Mother to Child Transmission (PMTCT) of HIV. METHODS: The trial is a cluster randomized controlled trial that is being implemented in Umlazi which is a peri-urban settlement with a total population of 1 million close to Durban in KwaZulu Natal, South Africa. The trial consists of 30 randomized clusters (15 in each arm). A baseline survey established the homogeneity of clusters and neither stratification nor matching was performed. Sample size was based on increasing HIV-free survival from 74% to 84%, and calculated to be 120 pregnant women per cluster. Primary outcomes are higher levels of HIV free survival and levels of exclusive and appropriate infant feeding at 12 weeks postnatally. The intervention is home based with community health workers delivering two antenatal visits, a postnatal visit within 48 hours of birth, and a further four visits during the first two months of the infants life. We are undertaking programmatic and cost effectiveness analysis to cost the intervention. DISCUSSION: The question is not merely to develop an efficacious package but also to identify and test delivery strategies that enable scaling up, which requires effectiveness studies in a health systems context, adapting and testing Asian community-based studies in various African contexts

The Impact of a Community-based Pilot Health Education Intervention for Older People as Caregivers of Orphaned and Sick Children as a Result of HIV and AIDS in South Africa

The increasing HIV and AIDS epidemic in South Africa poses a substantial burden to older people, in particular older women who mainly provide care for sick adult children and their grandchildren who have become orphaned and rendered vulnerable by the death or illness of their parents. In this study, 202 isiXhosa speaking older caregivers from Motherwell in the Eastern Cape Province of South Africa were trained to provide care for grandchildren and adult children living with HIV or AIDS. Based on a community needs assessment, a health education intervention comprising four modules was designed to improve skills and knowledge which would be used to assist older people in their care-giving tasks. Some topics were HIV and AIDS knowledge, effective intergenerational communication, providing home-based basic nursing care, accessing social services and grants, and relaxation techniques. Structured one-on-one interviews measured differences between pre-intervention and post-intervention scores among those who attended all four modules vs. those that missed one or more of the sessions. The results demonstrated that older people who participated in all four workshops perceived themselves more able and in control to provide nursing care. The participants also showed a more positive attitude towards people living with HIV or AIDS and reported an increased level of HIV and AIDS knowledge. The results provided valuable information upon which the development of future interventions may be based and psychosocial and structural needs of the older caregivers may be addressed by relevant stakeholders
