Background: Population-based data show high proportions of severe cases of cerebral palsy (CP) in resource-poor regions such as sub-Saharan Africa, where most children have potentially preventable risk factors (factors that may increase the likelihood of CP occurrence but can be mitigated through medical interventions).
Objectives: This study aimed to describe the demographic and clinical profile of children living with CP accessing services at Tygerberg Hospital over a period of 10 years (2010-2020), identify the potential gaps in care (proportion of individuals in a country requiring but not receiving suboptimal or inadequate care), and comparison with a similar study at the same centre two decades ago.
Method: This 10-year retrospective study investigated causes and morbidities in children with CP, attending a central hospital in the Western Cape, South Africa.
Mathematical models may aid researchers in describing biological processes, like growth, in animals. This study aimed to collect the body weight data of 18 Boer goat castrates and 20 Boer goat does, from birth until maturity, to model growth and determine growth trends. This is a novel investigation as sufficient information on an age-weight database for these two Boer goat sexes from birth to maturity, is lacking.

We aim to describe the impact of living with a durable LVAD on sexual quality of life (QOL), depression, and anxiety in patients and their partners.
Methods And Results: In this single-center, prospective, observational study, patients ≥4 months after LVAD implantation and their partners completed the Sexual Activities in Left Ventricular Assist Device Patients or Partners questionnaire to assess their sexual QOL, the 8-item Patient Health Questionnaire (PHQ-8) to assess symptoms of depression and the 7-item Generalized Anxiety Disorder (GAD-7) to assess symptoms of anxiety.
Article Synopsis
- - Over 30% of the global population is affected by anaemia, particularly iron deficiency anaemia, which is often linked to gastrointestinal issues; thus, a referral to a gastroenterologist is crucial for diagnosis.
- - In sub-Saharan Africa, new guidelines aim to improve management of patients with iron deficiency by focusing on the evaluation of gastrointestinal causes, enhancing clinical outcomes, and ensuring efficient use of blood resources.
- - The guidance document was created through collaboration among 21 experts in gastroenterology and haematology, using a structured process that included literature reviews, drafting recommendations, and multiple rounds of consensus voting.
Background: Little is known about the relationship between cytomegalovirus (CMV) infections and donor-derived cell-free DNA (dd-cfDNA) in heart transplant recipients.
Methods: In our study, CMV and dd-cfDNA results were prospectively collected on single-organ heart transplant recipients. If the CMV study was positive, a CMV study with dd-cfDNA was repeated 1-3 months later.
