Background: As healthcare recipients and individuals affected by antimicrobial resistance (AMR), patients and their carers can be engaged in infection prevention and control (IPC) and antimicrobial stewardship (AMS) initiatives to manage AMR. To effectively participate in these initiatives, patients and carers need to understand general terms used in infection care. We explored awareness of commonly used infection-related terms among patients and carers in the surgical out-patient of a tertiary academic hospital.
View Article and Find Full Text PDFBackground: Heart transplantation in South Africa faces numerous challenges related to organ scarcity and unequal access to advanced heart therapy. There is an urgent need to analyse the current transplant referral pathway to optimise equitable access to transplantation.
Objectives: To provide an audit of heart transplant referrals to Groote Schuur Hospital, Cape Town, over a 23-year period, focusing on patient demographics, indications for referral, waiting-list dynamics, and transplant referral outcomes.
Purpose: Aortic valve disease (AVD) affects millions of people around the world, with no pharmacological intervention available. Widely considered a multi-faceted disease comprising both regurgitative pathogenesis, in which retrograde blood flows back through to the left ventricle, and aortic valve stenosis, which is characterized by the thickening, fibrosis, and subsequent mineralization of the aortic valve leaflets, limiting the anterograde flow through the valve, surgical intervention is still the main treatment, which incurs considerable risk to the patient.
Results: Though originally thought of as a passive degeneration of the valve or a congenital malformation that has occurred before birth, the paradigm of AVD is shifting, and research into the inflammatory drivers of valve disease as a potential mechanism to modulate the pathobiology of this life-limiting pathology is taking center stage.
Purpose: Coronary artery bypass grafting (CABG) on cardiopulmonary bypass (CPB) is associated with myocardial ischemia-reperfusion injury (IRI), which may limit the benefit of the surgery. Both experimental and clinical studies suggest that Intralipid, a lipid emulsion commonly used for parenteral nutrition, can limit myocardial IRI. We therefore aimed to investigate whether Intralipid administered at reperfusion can reduce myocardial IRI in patients undergoing CABG on CPB.

While the young age of such patients largely prescribes replacement with mechanical prostheses, reliable anticoagulation management is often unattainable under the prevailing socioeconomic circumstances. Cases of patients with clotted valves presenting for emergency surgery as a consequence of poor adherence to anticoagulation control are frequent.

Background: Pulmonary endarterectomy (PEA) is the only definitive and potentially curative therapy for chronic thromboembolic pulmonary hypertension (CTEPH), associated with impressive improvements in symptoms and haemodynamics. However, it is only offered at a few centres in South Africa. The characteristics and outcomes of patients undergoing PEA in Cape Town have not been reported previously.

Antibiotic stewardship (AS) interventions predominantly focus on prescribers. This study investigated the influence and participation of inpatients in infection-related care, including antibiotic decision-making, within and across two tertiary hospitals in South Africa (Cape Town) and India (Kerala).

However, there are few data about the role of surgery when combined with newer drugs. There are no outcome data from TB endemic countries, and the prognostic significance of pre-operative PET-CT remains unknown.

The primary purpose of the initial report is to document the preoperative demographics, and the preoperative and operative risk factors by individual prosthesis and by Western and Developing populations.

Method: A scoping review of the literature was conducted. PubMed, Web of Science, Scopus, and grey literature sources were searched using predefined search criteria for policies, guidelines, and studies in the English language.

Pulmonary hydatid disease is almost exclusively caused by the infestation of the larval stage of Echinococcus granulosus. Humans are infected, accidentally, through the faeco-oral route by the ingestion of food and milk, contaminated by dog faeces containing the ova of parasites or direct contact with dogs. We describe an unusual cause of massive haemoptysis in a young male who had bilateral lung hydatid cysts as well as a large splenic hydatic cyst.

Using innovative visual mapping, alongside traditional qualitative methods, we studied how surgical team dynamics and communication patterns influence infection-related decision making.
Materials/methods: Between May and November 2019, data were gathered through direct observations of ward rounds and face-to-face interviews with ward round participants in three high infection risk surgical specialties at a tertiary hospital in South Africa.
Objectives: To investigate the drivers for infection management and antimicrobial stewardship (AMS) across high-infection-risk surgical pathways.
Methods: A qualitative study-ethnographic observation of clinical practices, patient case studies, and face-to-face interviews with healthcare professionals (HCPs) and patients-was conducted across cardiovascular and thoracic and gastrointestinal surgical pathways in South Africa (SA) and India. Aided by Nvivo 11 software, data were coded and analysed until saturation was reached.
The concept of tissue engineering evolved long before the phrase was forged, driven by the thromboembolic complications associated with the early total artificial heart programs of the 1960s. Yet more than half a century of dedicated research has not fulfilled the promise of successful broad clinical implementation. A historical account outlines reasons for this scientific impasse.

Whole body temperature-controlled perfusion has been applied to limit reperfusion injury and minimize ischemia. We describe the full recovery of a patient after the application of rapid hypothermia following an intraoperative aortic rupture with ten minutes of absent cerebral blood flow.
View Article and Find Full Text PDFLung transplantation is an important therapy for end-stage respiratory failure in patients who have exhausted other therapeutic options. The lung is unique among solid-organ transplants in that it is exposed to the outside environment, and undergoes continuous stimulation from infectious and non-infectious agents, which may play a part in upregulating the immune response to the allograft. Despite induction immunosuppression and the use of aggressive maintenance regimens, acute allograft rejection is still a major problem, especially in the first year after transplant, with important diagnostic and therapeutic challenges.

Lung transplantation (LT) is a robust therapy for advanced lung disease, which offers recipients extended and good-quality survival. In South Africa (SA), patients have historically had limited access to this therapy, particularly if unfunded. LT has been used as a successful therapeutic intervention for a wide variety of end-stage pulmonary parenchymal and vascular diseases, but the most common diseases that lead to LT are chronic obstructive pulmonary disease, interstitial lung disease, cystic fibrosis, alpha-1-antitrypsin deficiency and pulmonary arterial hypertension.

The aim of this study was to determine the long-term survival and clinical outcomes after isolated aortic valve replacement in patients with rheumatic heart disease in a Sub-Saharan country where follow-up of indigent patients is often challenging.
Methods: A retrospective review of 969 aortic valve replacements performed between 2003 and 2013 was conducted at Cape Town's Groote Schuur Hospital.
