    HIV-1 compartmentalisation is likely to have important implications for a preventative vaccine as well as eradication strategies. We genetically characterised HIV-1 subtype C variants in lymph nodes, peripheral blood mononuclear cells and plasma of six antiretroviral (ART) naïve individuals and four individuals on ART. Full-length env (n = 171) and gag (n = 250) sequences were generated from participants using single genome amplification. Phylogenetic relatedness of sequences was assessed, and compartmentalisation was determined using both distance and tree-based methods implemented in HyPhy. Additionally, potential associations between compartmentalisation and immune escape mutations were assessed. Partial viral compartmentalisation was present in nine of the ten participants. Broadly neutralising antibody (bnAb) escape was found to be associated with partial env compartmentalisation in some individuals, while cytotoxic T lymphocyte escape mutations in Gag were limited and did not differ between compartments. Viral compartmentalisation may be an important consideration for bnAb use in viral eradication

    Aim: The ability of a hen egg white bovine colostrum supplement to prevent severe COVID-19 was tested in a double-blind randomized control study. Methods: Adults with mild/moderate COVID-19, risk factors for severe disease, and within 5 days of symptom onset were assigned to the intervention (n = 77) or placebo (n = 79) arms. Symptoms were documented until day 42 post-enrollment and viral clearance was assessed at 11-13 days post-symptom onset. Results: One participant developed severe COVID-19. The severe-type symptom score was lower in the active arm at 11-13 days post-symptom onset (p = 0.049). Chest pain, fever/chills, joint pain/malaise, and sore throat were significantly less frequent in the active arm. No differences in viral clearance were observed. Conclusion: The intervention reduced symptoms of mild/moderate COVID-19

    Reflections on the concomitants of the restrictive visitation policy during the COVID-19 pandemic : an ubuntu perspective

    Get PDF
    Caregiving is a prominent concept in the Ubuntu philosophy, and caring and visitation of the sick is regarded as an example of Ubuntu. The restrictive visitation policy adopted in the hospitals during the coronavirus disease 2019 (COVID-19) pandemic affected the exhibition of this concept among patients, nurses, and families. The narrative inquiry was used to explore the reflections of the participants on the impact caused by the nonvisitation policy experienced during the first and second waves of the COVID-19 pandemic in South Africa. The narrative inquiry approach allowed the participants to tell their story as it is unique to them. The study used purposive sampling technique to select five participants for the webinar. Three themes emerged from the narrated stories which are 1) moral anguish of the caregivers; 2) mental health instability, and 3) erosion of trust in health care practitioners (HCPs). The non-visitation hospital policy was intended to reduce the danger of spreading COVID-19 within and outside the hospital; however, the care provided was devoid of the values of Ubuntu such as mutual respect, relational, responsibility, reciprocity, and interconnectedness. In retrospect, a case-by-case application of the policy would reduce the non-desirable effect of the policy on the patients, nurses, and patients’ family members.https://www.frontiersin.org/journals/sociologydm2022Nursing Scienc

    Haulout site selection by southern elephant seals at Marion Island

    Get PDF
    Using data from an ongoing mark-resight programme at Marion Island, we tested empirically whether southern elephant seals prefer certain terrestrial sites to others during the breeding, moulting and winter haulouts, and whether the pattern of site use is the same for different age and sex groups. Southern elephant seals preferred some sites, while discriminating against other sites, with different age and sex classes using different sites for certain haulout events. Wintering young animals did not show strong site selection. Some popular sites were used for all haulouts by all age and sex groups, and apparently have all the requirements of a good site for terrestrial haulout by southern elephant seals. Site selection becomes more apparent with age, suggesting the role of haulout experience in site selection

    Communication of health messages using theatre: Appreciative inquiry from Ubuntu theatre group

    Get PDF
    Background: Theatre involves expressing meaning in a collaborative art using words, movements, and visual elements. However, theatre remains poorly used as a viable teaching strategy or a method for communicating health messages. Instead, it is relegated to solemnly transmitting indigenous knowledge. Aim: To explore and describe communication of educational health messages through theatre using an appreciative inquiry approach. Setting: The study was conducted among the Ubuntu theatre group from a rural province in South Africa. The group is famous for using theatre to communicate educational health messages through the lens of Ubuntu philosophy. Methods: A qualitative exploratory descriptive design was followed. A non-probability purposive sampling was used to select thirteen members of the Ubuntu theatre group. Data were collected by two moderators from the two focus group discussions through conference calls. Deductive thematic content data analysis was used to describe the 4-Ds of appreciative inquiry. Results: Theatre is a playful pedagogy that can cut through language and cultural barriers when used to communicate educational health messages. There is a need to formalise it as an alternative pedagogy within the health care sciences curriculum. Furthermore, the sustainability of theatre as an educational tool is dependent on expanding educational practices, documenting its success stories and periodical in-service training. Conclusion: Using Ubuntu innovation to communicate complex educational health messages through theatre can maximise learning. This study recommends that Ubuntu-infused health messages be conveyed using theatre. Contribution: The study adds to the body of knowledge by presenting Ubuntu innovation in communicating health messages through theatre

    Effect of thermal treatment and storage on bioactive compounds, organic acids and antioxidant activity of baobab fruit (Adansonia digitata) pulp from Malawi

    Get PDF
    Bioactive compounds of baobab (Adansonia digitata) pulp from Malawi were investigated. The effect of thermal treatment and storage on selected quality attributes of the juice was also evaluated. Organic compounds were analysed by HPLC; total phenol content (TPC) and total antioxidant activity (FRAP, ABTS and DPPH) were measured by spectrophotometry. Malawi baobab pulp contains high levels of procyanidin B2 (533 ± 22.6 mg/100 g FW), vitamin C (AA + DHA) (466 ± 2.5 mg/100 g FW), gallic acid (68.5 ± 12.4 mg/100 g FW) and (−)-epicatechin (43.0 ± 3.0 mg/100 g FW) and showed a maximum TPC of 1.89 × 103 ± 1.61 mg GAE/100 g FW. The maximum antioxidant activity was 2.81 × 103 ± 92.8 mg TEAC/100 g FW for FRAP, 1.52 × 103 ± 17.1 mg TEAC/100 g FW for ABTS and 50.9 ± 0.43% DPPH for DPPH. Thermal pasteurisation (72 °C, 15 s) retained vitamin C which further showed extended half-life under refrigeration temperature (6 °C). Procyanidin B2, (−)-epicatechin, TPC and antioxidant activity fluctuated during storage. Antioxidant activity was significantly correlated (p ≤ 0.05) with bioactive compounds and TPC
