Predicting the need for blood during cardiopulmonary bypass
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: AR Coetzee --- Department of Anesthesiology and Critical Care, South Africa JF Coetzee --- Department of Anesthesiology and Critical Care, South AfricaBackground: Haematocrit (Hct) values <18%-20% during cardiopulmonary bypass (HctCPB) are potentially unsafe. Aims: 1. To predict when banked-blood should be pre-issued. 2. To evaluate the sparing-effect of banked-blood by autologous blood transfusions. Methods: An equation for prediction of HctCPB (Hctpred),... -
Oxygen dissociation curves of whole blood from the Egyptian free-tailed bat, Tadarida aegyptiaca E. Geoffroy, using a thin-layer optical cell
Item type: Journal Article • Journal: African Zoology • Authors: W.J. van Aardt --- School of Environmental Sciences and Development, South Africa G.N. Bronner --- Department of Zoology, South Africa Marie-Louise de Necker --- School of Environmental Sciences and Development, South AfricaTadarida aegyptiaca (mean body mass 13.5 g) is a fast flying insectivorous bat that hunts in open areas for extended periods, covering extensive distances during its foraging bouts. Whole blood samples taken from the wing arteries were analysed for 2,3-diphosphoglyceric... -
Microfilarial infections associated with body mass loss of Village Weavers Ploceus cucullatus
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Andong F Atawal --- AP Leventis Ornithological Research Institute, Nigeria Anthony C Mgbeahuruike --- Department of Veterinary Pathology and Microbiology, Faculty of Veterinary Medicine, Nigeria Martijn Hammers --- AP Leventis Ornithological Research Institute, NigeriaHaemoparasitic infections in wild birds have been widely studied in order to understand parasite–host relation- ships, but our understanding of their impact on the host's fitness is still limited. In this study, we quantified the associations between microfilarial infections and... -
Acute changes in haematocrit leading to polycythaemia in late-onset hypogonadism patients that receive testosterone replacement therapy: a South African study
Item type: Journal Article • Journal: Journal of Endocrinology, Metabolism and Diabetes of South Africa • Authors: Jesslee du Plessis --- Medicine Usage in South Africa (MUSA), North-West University, South Africa Hermanus Lambertus Bester --- Private Hospital, Emalahleni, South Africa, Marlene Julyan --- Medicine Usage in South Africa (MUSA), North-West University, South Africa Marike Cockeran --- School for Computer, Statistical and Mathematical Sciences, North-West University, South AfricaBackground: According to the literature, parenteral testosterone replacement therapy (TRT)-induced polycythaemia is associated with cardiovascular events. No or minimal data exist for the prevalence of TRT-induced polycythaemia in late-onset hypogonadism (LOH) patients from South Africa. Polycythaemia is the side effect... -
Intercolony health evaluation of wild African penguins Spheniscus demersus, in relation to parasites, along the southwest coast of South Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: MPA Espinaze --- , South Africa C Hui --- , South Africa L Waller --- , South Africa S Matthee --- , South AfricaClinical parameters of African penguins Spheniscus demersus have been recorded mostly from birds admitted to rehabilitation centres and are typically presented as mean values across a region. It is uncertain whether these values are representative of wild penguins and whether...
