BACKGROUND: Primary Health Care (PHC) is well suited for management of low back pain (LBP). Prevalence of (chronic) LBP is suspected to be high among visitors of the South African primary care centers, but currently no information exists on prevalence or guideline adherence.OBJECTIVES: To establish if treatment received for LBP in public PHC in the Cape Town area compares with international evidence based guidelines.METHODS: Cluster randomization determined the 8 community health centres where the study took place. A measurement tool was developed and validated for this population. Descriptive analysis and logistic regression analytical techniques were applied.RESULTS: 489 participants (mean age: 44.8) were included in this study. Lifetime prevalence was 73.2% and 26.3% suffered from chronic low back pain (CLBP) . Pain medication was the only form of treatment received by 90% of the sample. Interventions received seemed to be unrelated to type of LBP (acute, sub acute and chronic). Referral to physiotherapy, education and advice to stay active were rarely done. Participants expressed low satisfaction with treatment.CONCLUSIONS: Current management of LBP at PHC level appears to be ineffective and not conform guidelines. Further South African research should focus on barriers as well as measures to be taken for implementation of LBP guidelines.

Urban planning will benefit from tools that can assess the vulnerabilityto thermal stress in urban dense cities. Detailed quick-scan heat stressmaps, as made in this study for Johannesburg, have proven valuable inthe decision-making process on this topic. It raised awareness on theurgent need to implement measures to tackle the effects of climatechange and urbanization. Awareness on heat stress has led to theimplementation of measures to mitigate the effects of climate change.As in other countries, nature-based solutions (e.g. green roofs and walls,swales, rain gardens, planting trees etc) are considered in urban areasin South Africa for various reasons. The awareness of the effect ofnature based solutions on heat stress is still low, which can be improvedby the use of heat stress maps. Some of these measures are alreadymapped on the open source web tool, Climate-scan(www.climatescan.nl) for international knowledge exchange aroundthe globe.
In veel Afrikaanse landen zien we een inperking van de maatschappelijke ruimte (‘civic space’). Deze ruimte is cruciaal om in democratische staten transparantie, vrijheid van meningsuiting en verantwoording van bestuur te realiseren. In een steeds sterke digitaliserende maatschappij wordt toegang tot digitale middelen een mensenrecht. Daar waar regeringen proberen hun burgers en organisaties dat recht tot digitale informatievoorziening en –uitwisselingen te ontnemen komen de Sustainable Development Goals in het gedrang. Doel African Digital Rights Network (ADRN) wil inzicht verkrijgen in de stakeholders ne technologieën die betrokken zijn net het openen of onderdrukken van de online maatschappelijke ruimte (‘civic space’). Het netwerk beoogt bij te dragen aam empowerment van burgers om hun digitale mensenrechten uit te oefenen. Resultaten ADRN heeft een vergelijkende studie van 10 Afrikaanse landen uitgevoerd naar het gebruik van digitale technologieën voor het openen of onderdrukken van de online maatschappelijke ruimte (‘civic space’). Het project heeft onder andere geleidt tot de volgende publicatie: Mapping the Supply of Surveillance Technologies to Africa: Case Studies from Nigeria, Ghana, Morocco, Malawi, and Zambia Looptijd 01 mei 2020 - 20 april 2021 Aanpak ADRN organiseert een netwerk van onderzoekers, analisten, digitale rechtenorganisaties en activisten om de dynamiek van het openen en onderdrukken van de digitale maatschappelijke ruimte in kaart te brengen. Het netwerk bouwt op een interdisciplinaire onderzoeksaanpak o.l.v. het Institute for Development Studies, een vooraanstaand onderzoeksinstituut. Relevantie van het project Het onderzoek leidt tot aanbevelingen voor o.a. beleidsmakers en maatschappelijke organisaties ter bevordering van de digitale maatschappelijke ruimte. Daarnaast worden digitale tools en trainingsmateriaal gefaciliteerd voor het monitoren van ontwikkelingen en dreigingen van de digitale maatschappelijke ruimte.

Micro and macro algae are a rich source of lipids, proteins and carbohydrates, but also of secondary metabolites like phytosterols. Phytosterols have important health effects such as prevention of cardiovascular diseases. Global phytosterol market size was estimated at USD 709.7 million in 2019 and is expected to grow with a CAGR of 8.7% until 2027. Growing adoption of healthy lifestyle has bolstered demand for nutraceutical products. This is expected to be a major factor driving demand for phytosterols. Residues from algae are found in algae farming and processing, are found as beachings and are pruning residues from underwater Giant Kelp forests. Large amounts of brown seaweed beaches in the province of Zeeland and are discarded as waste. Pruning residues from Giant Kelp Forests harvests for the Namibian coast provide large amounts of biomass. ALGOL project considers all these biomass residues as raw material for added value creation. The ALGOL feasibility project will develop and evaluate green technologies for phytosterol extraction from algae biomass in a biocascading approach. Fucosterol is chosen because of its high added value, whereas lipids, protein and carbohydrates are lower in value and will hence be evaluated in follow-up projects. ALGOL will develop subcritical water, supercritical CO2 with modifiers and ethanol extraction technologies and compare these with conventional petroleum-based extractions and asses its technical, economic and environmental feasibility. Prototype nutraceutical/cosmeceutical products will be developed to demonstrate possible applications with fucosterol. A network of Dutch and African partners will supply micro and macro algae biomass, evaluate developed technologies and will prototype products with it, which are relevant to their own business interests. ALGOL project will create added value by taking a biocascading approach where first high-interest components are processed into high added value products as nutraceutical or cosmeceutical.
