Patient journey, disease burden, and functional disability in patients with axial spondyloarthritis in South Africa: results of International Map of Axial Spondyloarthritis (IMAS).

Objective: To assess the unmet needs of South Africans with axial spondyloarthritis (axSpA) focusing on the patient journey, functional disability, and health-related quality of life.

Methods: One hundred forty-six South African axSpA patients completed the International Map of Axial Spondyloarthritis (IMAS) online survey. Patient journey, functional disability, activities of daily living, and psychological stress were analyzed in relation to socio-demographic characteristics, disease activity, diagnostic delay, extra-musculoskeletal manifestations, and drug therapy.

Demanding doctorability for abortion on request: a conversation analysis of pre-abortion counselling in public hospitals in the Eastern Cape, South Africa.

Background: Research on abortion counselling generally uses retrospective interviewing regarding providers' and users' experiences. In this article we explore how requests for abortion are made and received in real time in (officially non-mandatory) pre-abortion counselling conducted by nurses and counsellors in South African public abortion clinics.

Methods: To capture turn-by-turn interactions, we recorded, using consecutive sampling, 28 sessions at three abortion clinics in 2017/2018.

The psychological impact of COVID-19 on frontline doctors in Tshwane public hospitals.

Background: The coronavirus disease 2019 (COVID-19) pandemic placed immense pressure on frontline doctors. Burnout is a psychological syndrome that develops in response to chronic work stress. It consists of emotional exhaustion (EE), depersonalisation (DP) and reduced personal accomplishment (PA).

Potential of bone morphogenetic protein-7 in treatment of lupus nephritis: addressing the hurdles to implementation.

Up to 50% of systemic lupus erythematosus (SLE) patients world-wide develop lupus nephritis (LN). In low to middle income countries and in particular in sub-Saharan Africa, where SLE is prevalent with a more aggressive course, LN and end stage renal disease is a major cause of mortality. While developed countries have the funding to invest in SLE and LN research, patients of African descent are often underrepresented in clinical trials.

The transcriptional activity of progestins used in contraception and menopausal hormone therapy via progesterone receptor A is dependent on the density of the receptor.

Studies directly comparing the efficacies and potencies of multiple progestins used in contraception and menopausal hormone therapy (MHT) in parallel via human progesterone receptor isoform A (PR-A) in the same model system are limited, and how these parameters are influenced by the density of PR-A are unclear. This is surprising as it is known that the expression levels of PR-A vary in different tissues and diseases. We thus determined for the first time the relative efficacies and potencies for transactivation of the natural PR ligand, progesterone (P), the PR-specific agonist promegestone (R5020), and selected progestins from all four generations in parallel via different densities of PR-A overexpressed in the MDA-MB-231 breast cancer cell line.

Lupus myocarditis: review of current diagnostic modalities and their application in clinical practice.

Lupus myocarditis (LM) is a potentially fatal manifestation of SLE, occurring in 5-10% of patients. Clinical manifestations may vary from an unexplained tachycardia to fulminant congestive cardiac failure (CCF). With no single clinical or imaging modality being diagnostic, a rational and practical approach to the patient presenting with possible LM is essential.

Access to chloroquine in patients with rheumatic and musculoskeletal diseases attending rheumatology outpatient clinics during the COVID-19 pandemic.

Herbal medicines made from the bark of the Cinchona tree, and later quinine, have been widely used for centuries to treat medical conditions such as tropical malaria. More recently, chloroquine (CQ) and its synthetic derivatives have been used as antimalarials and to treat systemic lupus erythematosus, rheumatoid arthritis, and in the past 14 months or so, COVID-19 pneumonia. Anecdotal evidence and the erratic covering through social media of its potential efficacy in the treatment of COVID-19 pneumonia have resulted in the widespread off-label use of CQ in South Africa and worldwide.

Outcome of clinical and subclinical myocardial injury in systemic lupus erythematosus - A prospective cohort study.

Objectives: To determine the outcome of subclinical lupus myocarditis (LM) over twelve months with regards to: mortality; incidence of clinical LM and change in imaging parameters (echocardiography and cardiac magnetic resonance [CMR]). To evaluate the impact of immunosuppression on CMR evidence of myocardial tissue injury.

Methods: SLE patients with and without CMR evidence of myocardial injury (as per 2009 Lake Louise criteria [LLC]) were included.

A retrospective review of the adverse effects of biological therapy and reasons for its discontinuation in a resource-limited setting.

Background: Biological disease-modifying antirheumatic drug therapies have become the gold standard of treatment for refractory rheumatic conditions in well-resourced countries. There is a significant risk of infection and reactivation of latent infections, in particular tuberculosis, with the use of biological therapies. Their safety and reasons for discontinuation in a resource-limited environment are still unclear.

Serum cytokine levels associated with myocardial injury in systemic lupus erythematosus.

Objectives: To identify cytokines, markers of endothelial activation [soluble vascular cell adhesion molecule-1 (sVCAM-1)] and myocyte strain [soluble ST2 (sST2)] associated with myocardial injury (MInj) in SLE, classified by cardiac magnetic resonance (CMR) criteria.

Methods: CMR was performed on patients with SLE, identifying stages of MInj (inflammation and necrosis or fibrosis). Data captured included: clinical assessment, laboratory and serological analyses, cytokine (IL-1β, IL-1Ra, IL-2, IL-6, IL-10, IL-17, IL-18, TNF-alpha), sVCAM-1 and sST2 levels.

Characterisation of progestins used in hormonal contraception and progesterone via the progesterone receptor.

Different progestogens are widely used in hormonal therapy and mediate their therapeutic actions via the progesterone receptor (PR). Little published data exist on their relative efficacies and potencies via the PR, while those available may be confounded by off-target receptors, different methodologies and model systems. We performed dose-response analysis to investigate the efficacies and potencies for transcription of progesterone and several progestins widely used in contraception via the B isoform of human PR (PR-B).

Radial artery dilatation to improve access and lower complications during coronary angiography: the RADIAL trial.

Aims: The aim of this study was to explore the use of prolonged occlusion flow-mediated dilatation (PO-FMD) to dilate the radial artery prior to cannulation to increase cannulation success, reduce puncture attempts and reduce access-site complications in transradial coronary angiography.

Methods And Results: A total of 1,156 patients undergoing transradial coronary angiography were randomised into PO-FMD and sham PO-FMD groups. PO-FMD was achieved by a 10-minute inflation of a blood pressure cuff on the arm to above systolic pressure, followed by deflation with resultant radial artery dilation.

Psychological knowledge production about abortion: the politics of location and representation.

Background: Despite considerable psychology research being conducted on abortion, there has been no study of the history of psychological knowledge production on the topic. The aim of our research was to analyse journal articles published in English language psychology journals using a politics of location and of representation analytical lens.

Study Design: A systematic search for articles published on abortion in psychology journals from 1960 to 2015 was conducted.

A Global Public Health Perspective: Facilitating Access to Assistive Technology.

Clinicians should not overlook vulnerable populations with limited access to assistive technology (AT), the importance of collaboration in multidisciplinary teams, advocacy for enabling environments, and supportive health systems. Resources, a model of care, and recommendations can assist clinicians in contributing to changing attitudes, expanding knowledge, and improving the lives of many.The increasing availability of innovative advances in AT can immeasurably enhance the quality of life of people with disabilities.

Surgical skills deficiencies and needs of rural general practitioners in South Africa.

Background: At present, much of the global surgical workforce consists of non-specialist physicians (general practitioners (GPs)) whose only formal surgical training was in medical school as an undergraduate. However, there is widespread concern that GPs do not have the skills necessary to deliver essential surgical care in a rural setting. This requires that a specific training programme be developed to train rural GPs in essential surgical skills for rural settings.

Robust forensic matching of confiscated horns to individual poached African rhinoceros.

Black and white rhinoceros (Diceros bicornis and Ceratotherium simum) are iconic African species that are classified by the International Union for the Conservation of Nature (IUCN) as Critically Endangered and Near Threatened (http://www.iucnredlist.org/), respectively [1].

Speckle tracking echocardiography in acute lupus myocarditis: comparison to conventional echocardiography.

Aims: Lupus myocarditis occurs in 5-10% of patients with systemic lupus erythematosus (SLE). No single feature is diagnostic of lupus myocarditis. Speckle tracking echocardiography (STE) can detect subclinical left ventricular dysfunction in SLE patients, with limited research on its utility in clinical lupus myocarditis.

The Use of Key Informant Method for Identifying Children with Blindness and Severe Visual Impairment in Developing Countries.

Purpose: An estimated 19 million children are visually impaired; of these, 1.4 million are irreversibly blind. A key challenge is to identify them early in life to benefit maximally from visual rehabilitation, and/or treatment.

Perforated appendicitis presenting as a thigh abscess: a lethal combination.

Typical cases of acute appendicitis have excellent treatment outcomes, if managed appropriately.1 We discuss an unusual case of perforated retrocaecal appendicitis that presented as a right thigh abscess without prominent abdominal symptoms, which highlights the lethal nature of advanced appendicitis even when appropriate surgical therapy is instituted.
