Anthropometric nutritional status of children (0–18 years) in South Africa 1997–2022: a systematic review and meta-analysis
Kruger, Herculina Salome; Visser, Marina; Malan, Linda; Zandberg, Lizelle; Wicks, Mariaan; Ricci, Cristian; Faber, Mieke (Cambridge University Press, 2023-10)Objective: To conduct a comprehensive systematic review and meta-analysis of the available literature on the anthropometric nutritional status of South African infants and children, 0–18 years old and to report on trends ... -
Comparison of test performance of two commonly used multiplex assays to measure micronutrient and inflammatory markers in serum: results from a survey among pregnant women in South Africa
Chimhashu, Tsitsi; Verhoef, Hans; Symington, Elizabeth; Zandberg, Lizelle; Baumgartner, Jeannine; Malan, Linda; Smuts, Cornelius; Feskens, Edith; Melse-Boonstra, Alida (Cambridge University Press, 2024)The combined sandwich-ELISA (s-ELISA; VitMin Lab, Germany) and the Quansys Q-Plex™ Human Micronutrient Array (7-Plex) are multiplex serum assays that are used to assess population micronutrient status in low-income ... -
Evaluation of the cytotoxic properties, gene expression profiles and secondary signalling responses of cultured cells exposed to fumonisin B1, deoxynivalenol and zearalenone mycotoxins
Wentzel, Johannes F.; Lombard, Martani J.; Du Plessis, Lissinda H.; Zandberg, Lizelle (Springer, 2017)Mycotoxins are toxic secondary metabolites produced by a range of fungi and are common contaminants of agricultural crops. These toxins are chemically diverse and structurally stable, enabling them to enter the food ... -
Fibrinogen and clot-related phenotypes determined by fibrinogen polymorphisms: independent and IL-6-interactive associations
Cronjé, H. Toinét; Nienaber-Rousseau, Cornelie; Zandberg, Lizelle; De Lange, Zelda; Pieters, Marlien (PLoS, 2017)Interleukin-6 (IL-6) induces the expression of fibrinogen, and polymorphic variation within the fibrinogen genes is believed to alter the magnitude of this expression. The identification of the functional relevance of ... -
Gene interactions observed with the HDL-c blood lipid, intakes of protein, sugar and biotin in relation to circulating homocysteine concentrations in a group of black South Africans
Du Plessis, Jacomina P.; Melse-Boonstra, Alida; Zandberg, Lizelle; Nienaber-Rousseau, Cornelie (Elsevier, 2020)Background Elevated homocysteine (Hcy) is associated with several pathologies. Gene–diet interactions related to Hcy might be used to customize dietary advice to reduce disease incidence. To explore this possibility, we ... -
Genetic characterisation of delta-5 and delta-6 fatty acid desaturases and associations with fatty acid status in pregnant women of African descent
Prinsloo, Anika (North-West University (South-Africa), 2021)Introduction and aim - Globally, dietary habits have shifted over the years from a traditional rural diet to a more Westernised diet. This has caused a drastic change in the intake ratio of n-6:n-3 polyunsaturated fatty ... -
The implementation of the molecular characterisation of 3-methylcrotonyl-CoA carboxylase deficiency in South Africa
Zandberg, Lizelle (North-West University, 2006)The perception is that inborn errors of metabolism (IEM) are rare, but the reality is that more than 600 lEMs are now recognized. The organic aciduria, 3-methylcrotonyl-CoA carboxylase (MCC) deficiency arises when ... -
Nutrition during pregnancy and early development (NuPED) in urban South Africa: a study protocol for a prospective cohort
Symington, Elizabeth A.; Baumgartner, Jeannine; Malan, Linda; Zandberg, Lizelle; Ricci, Cristian; Smuts, Cornelius M. (BioMed Central, 2018)Background Adequate nutrition during pregnancy is important to ensure optimal birth outcomes, maternal health and offspring development. However, little is known about the dietary intake and nutritional status of pregnant ... -
Nutritional status of Tajik children and women: transition towards a double burden of malnutrition
Barth-Jaeggi, Tanja; Zandberg, Lizelle; Bahruddinov, Mutribjon; Kiefer, Sabine; Rahmarulloev, Sherali (Wiley, 2019)The double burden of malnutrition, an emerging concern in developing countries, can exist at various levels: individual, household, and population. Here, we explore the nutritional status of Tajik women (15–49 years) and ... -
The relationship of long-chain polyunsaturated fatty acid status with blood pressure in pregnant African women : the NuPED study
Kekana, K.K. (North-West University (South-Africa), 2021)Introduction - Globally, hypertensive disorders affect 10% of pregnancies and are the most common risk factors for maternal and perinatal morbidity and mortality. Between 2011 and 2013, 14.8 % of maternal mortalities ... -
Transcriptomic and functional characterisation of marginal and clinically severe 3-methylcrotonyl-CoA carboxylase deficiency
Zandberg, Lizelle (North-West University (South Africa), 2015)Urinary 3-hydroxyisovaleric acid and 3-methylcrotonylglycine are usually indicative of the possibility of 3-methylcrotonyl-CoA carboxylase (MCC) deficiency. In this study a South African family which presented with these ...
