Energy efficiency through the use of technology in South African industry
Abstract: South Africa’s increasing cost of industrial energy has recently caused the country to be ranked among the top five countries in the world with the most expensive industrial electricity tariffs. For various reasons, energy is often not optimally used in industry. According to Zavanella and Zanoni (2009), there has been a growing interest in more rational and responsible consumption of energy, especially in industrial processes and services. This research study demonstrates the use of technology for energy efficiency in the industry, in order to reduce energy consumed per unit produced on industrial process plants
Challenges and innovations brought about by the Covid-19 pandemic regarding medical and pharmacy education especially in Africa and implications for the future
Background: Multiple measures introduced early to restrict COVID-19 have dramatically impacted the teaching of medical and pharmacy students, exacerbated by the lack of infrastructure and experience with e-learning at the start of the pandemic. In addition, the costs and reliability of the Internet across Africa pose challenges alongside undertaking clinical teaching and practical programmes. Consequently, there is a need to understand the many challenges and how these were addressed, given increasingly complex patients, to provide future direction. Method: An exploratory study was conducted among senior-level medical and pharmacy educators across Africa, addressing four key questions, including the challenges resulting from the pandemic and how these were dealt with. Results: Staff and student members faced multiple challenges initially, including adapting to online learning. In addition, concerns with the lack of equipment (especially among disadvantaged students), the costs of Internet bundles, and how to conduct practicals and clinical teaching. Multiple activities were undertaken to address these challenges. These included training sessions, developing innovative approaches to teaching, and seeking ways to reduce Internet costs. Robust approaches to practicals, clinical teaching, and assessments have been developed. Conclusions: Appreciable difficulties to teaching arising from the pandemic are being addressed across Africa. Research is ongoing to improve education and assessments
Mental health care - a public health priority in South Africa
Mental health is an integral part of health and it includes an individual’s emotional, psychological and social well-being. Mental illness remains underreported and underdiagnosed, particularly in low- and middle-income countries, including South Africa. South Africa carries a huge burden of mental illnesses with the most prevalent being anxiety disorders, substance abuse disorders, mood disorders and depression. People with mental health conditions often face neglect in the health system as well as stigma and discrimination. This has resulted in poor health outcomes, isolation and high suicide rates, including amongst adolescents. The South African National Mental Health Policy Framework and Strategic Plan (2013–2020) aims to integrate mental health into the health system to provide quality mental health services that are accessible, equitable and comprehensive, particularly for community-based mental health. This article provides an overview of mental health care in South Africa, highlighting its public health importance
Case Report: Successful treatment of bilateral visual loss caused by HIV-associated optic neuritis
Optic neuritis is not an uncommon diagnosis in HIV-infected patients, but it is rarely idiopathic. We report a case of a young HIV-infected woman who developed optic neuritis as her presenting manifestation of HIV infection. She had initially experienced sudden-onset right-sided painful visual loss; the left eye had become involved within days. Bilateral swollen discs were apparent on fundoscopy. Investigations were performed for meningitis (including bacterial, cryptococcal, tuberculous and syphilitic types), auto-immune diseases, toxoplasma, rubella, cytomegalovirus, viral hepatitis, HTLV-1/2, HIV-1/2 and syphilis. The only positive result was a reactive HIV enzymelinked immunosorbent assay. The CD4 count was 85 cells/μl. A post-contrast magnetic resonance imaging scan of the brain illustrated enhancement of the optic nerves. Treatment was 3 days of intravenous methylprednisolone 1 g daily, followed by 11 days of oral prednisone 60 mg daily. Highly active antiretroviral therapy was initiated after 2 weeks. Vision improved from day 6 after commencement of steroid therapy, with ongoing recovery at 5 months
