Need for services for the care and prevention of congenital disorders in South Africa as the country’s epidemiological transition evolves

The lack of prioritisation of services for the care and prevention of congenital disorders is a global concern. Reducing child mortality (MDG4) can be achieved by middle- and some low-income nations, including South Africa (SA), by focusing on congenital disorders. We performed a situational analysis of epidemiological transition and services for congenital disorders in SA to highlight their renewed need, in the form of a review of epidemiological transition in SA from 1990 related to the HIV/AIDS epidemic and services for congenital disorders. In the early 1990s in SA decreasing infant and child mortality revealed the previously hidden burden of disease of congenital disorders. Approaches to confront this burden were developed and incorporated in national policy guidelines published in 2001. The emergent HIV epidemic buried the issue, and as services for HIV/AIDS developed, services for the care and prevention of congenital disorders were simultaneously neglected. They are now at a base lower than in 2001. Infant and child mortality rates are at a more advanced level than their previous best levels in the early 1990s, but they are stagnating. There is therefore a renewed need for services for the care and prevention of congenital disorders. The present limited state of these services must be rectified urgently. Services for the care and prevention of congenital disorders require prioritisation again in accordance with Resolution WHA63.17 of the World Health Organization, and to achieve the human dignity and constitutionally and legally enshrined rights of people affected by congenital disorders.

Regenerative medicines : a new regulatory paradigm for South Africa

Clinicians are increasingly using regenerative medicines to repair, replace, regenerate or rejuvenate lost, damaged or diseased genes, cells, tissues or organs. In South Africa, access to these novel gene therapies and cell and tissue-based products is limited. The human leukocyte antigen (HLA) diversity and a paucity of suitable HLA-identical unrelated donors, results in limited access to haematopoietic stem and progenitor cell transplantation (HSPCT). Cell-based products could increase this access. Genetic diversity can also manifest in local or region-specific rare congenital disorders, and in vivo gene therapies hold the promise of developing treatments and cures for these debilitating disorders. South Africa has a disproportionate mortality rate due to non-natural causes, with many surviving with permanent injuries and disabilities. Tissue-engineered cell-based products have the potential to restore many of those affected and improve quality of life and productivity. These factors create an urgency for South Africa to develop regenerative medicines to address the country's unique needs and to provide access to these new and innovative treatment modalities. Achieving this objective requires a well-coordinated effort by multiple stakeholders and role players. A critical component of a regenerative medicine ecosystem is establishing an enabling regulatory framework for these new classes of medicines. Here we provide a brief profile of South Africa, including its genetic diversity, economy, the impact of the burden of disease, health policy and the healthcare system. We address the regulation of medicines, how the existing framework can accommodate regenerative medicines, and the steps needed to establish a future regulatory framework.South African Medical Research Council (Extramural Unit, Stem Cell Research and Therapy) and the University of Pretoria (through the Institute for Cellular and Molecular Medicine).http://www.elsevier.com/locate/biochihj2023BiochemistryGeneticsImmunologyMicrobiology and Plant Patholog

Prevention of Congenital Disorders and Care of Affected Children: A Consensus Statement

As the Sustainable Development Goals are adopted by United Nations member states, children with congenital disorders remain left behind in policies, programs, research, and funding. Although this finding was recognized by the creation and endorsement of the 63rd World Health Assembly Resolution in 2010 calling on United Nations member states to strengthen prevention of congenital disorders and the improvement of care of those affected, there has been little to no action since then. The Sustainable Development Goals call for the global health and development community to focus first and foremost on the most vulnerable and those left behind in the Millennium Development Goal era. To maximize the opportunity for every woman and couple to have a healthy child and to reduce the mortality and severe disability associated with potentially avoidable congenital disorders and their consequences for the children affected, their families and communities, and national health care systems, we propose priority measures that should be taken urgently to address this issue

Assessment of functional capacity before major non-cardiac surgery: an international, prospective cohort study.

BACKGROUND: Functional capacity is an important component of risk assessment for major surgery. Doctors' clinical subjective assessment of patients' functional capacity has uncertain accuracy. We did a study to compare preoperative subjective assessment with alternative markers of fitness (cardiopulmonary exercise testing [CPET], scores on the Duke Activity Status Index [DASI] questionnaire, and serum N-terminal pro-B-type natriuretic peptide [NT pro-BNP] concentrations) for predicting death or complications after major elective non-cardiac surgery. METHODS: We did a multicentre, international, prospective cohort study at 25 hospitals: five in Canada, seven in the UK, ten in Australia, and three in New Zealand. We recruited adults aged at least 40 years who were scheduled for major non-cardiac surgery and deemed to have one or more risk factors for cardiac complications (eg, a history of heart failure, stroke, or diabetes) or coronary artery disease. Functional capacity was subjectively assessed in units of metabolic equivalents of tasks by the responsible anaesthesiologists in the preoperative assessment clinic, graded as poor (10). All participants also completed the DASI questionnaire, underwent CPET to measure peak oxygen consumption, and had blood tests for measurement of NT pro-BNP concentrations. After surgery, patients had daily electrocardiograms and blood tests to measure troponin and creatinine concentrations until the third postoperative day or hospital discharge. The primary outcome was death or myocardial infarction within 30 days after surgery, assessed in all participants who underwent both CPET and surgery. Prognostic accuracy was assessed using logistic regression, receiver-operating-characteristic curves, and net risk reclassification. FINDINGS: Between March 1, 2013, and March 25, 2016, we included 1401 patients in the study. 28 (2%) of 1401 patients died or had a myocardial infarction within 30 days of surgery. Subjective assessment had 19·2% sensitivity (95% CI 14·2-25) and 94·7% specificity (93·2-95·9) for identifying the inability to attain four metabolic equivalents during CPET. Only DASI scores were associated with predicting the primary outcome (adjusted odds ratio 0·96, 95% CI 0·83-0·99; p=0·03). INTERPRETATION: Subjectively assessed functional capacity should not be used for preoperative risk evaluation. Clinicians could instead consider a measure such as DASI for cardiac risk assessment.
