    A feasibility study to assess Imbrasia belina (mopane worm) sensitisation and related respiratory health outcomes in a rural community in Gwanda district, Zimbabwe
    (Springer Nature, 2021-02-22) Ndlovu, V.; Chimbari, M.; Sibanda, E.; Ndarukwa, P.
    Background Allergic diseases are considered to be some of the fastest growing chronic conditions in Africa. Of concern is the paucity of knowledge about the local environment and its role in allergic disease development. In response to this, we explored whether Imbrasia belina, a popular indigenous edible insect commonly known as mopane worm, is a potential allergen of clinical and public health significance in Zimbabwe. This study was intended to assess the plausibility and feasibility of this hypothesis with a view to evaluate the insect’s health impact in a larger study. Methods The study participants included male and female villagers aged 10 years and above in Gwanda district, Zimbabwe. Eligible participants who completed the household questionnaire were referred to the local clinic for skin prick tests and to measure lung function and allergic airway inflammation. Allergen sensitisation patterns were evaluated using 10 different inhalant allergen extracts including an in-house preparation of mopane worm. Lung function was measured with a Koko Legend spirometer, and fractional exhaled nitric oxide levels (FeNO) (NIOX VERO) were measured in participants with at least one abnormal spirometric parameter. Data was analysed using Stata version 13 software. Results Of the 46 eligible participants that completed the household questionnaire, 17 went to the clinic giving a response rate of 37%. The majority who completed the questionnaire were adults (91%) and the children (9%) were all female. The prevalence of sensitisation to Imbrasia belina was 50%, and the prevalence ranged from 22 to 72% for the other allergens including cockroach, mosquito and house dust mites. The data collection tools were safe and well tolerated by participants with no adverse events reported. Self-reported respiratory symptoms, abnormal lung function and elevated FeNO were recorded amongst participants sensitised to mopane worm. Conclusion Pre-defined feasibility criteria were met with the exception of a lower than expected response rate for clinic data collection in this pilot study. For the main study, modifying the sampling strategy and applying more consistent community engagement will improve the response rates.

    An Assessment of Financial Inclusion Challenges Among Women Vendors at the Bulawayo Vegetable Market
    (RSIS, 2024-05-10) Tshuma, N.; Kufa, A.T.; Sibanda, E.; Setoboli, T
    In the vibrant markets of Bulawayo, Zimbabwe, where women entrepreneurs thrive, a critical challenge persists: financial inclusion remains low. However, Mobile Financial Services (MFS) digital platforms have the potential to revolutionize access to affordable financial solutions for women entrepreneurs. Our study delved into the experiences of women vendors at the bustling Bulawayo Vegetable Market during the period from 2016 to 2023. Through a descriptive survey design, we aimed to uncover the hurdles faced by these enterprising women as they navigated the realm of MFS. Findings revealed that many women were unaware of the existence and benefits of MFS. The lack of knowledge hindered their participation. Proper documentation essential for accessing financial services remained elusive for some. Without it, women faced barriers in utilizing MFS. Limited education posed a significant obstacle. Basic financial literacy and digital skills were prerequisites for effective MFS adoption. The absence of digital skills impeded women from confidently using mobile platforms for financial transactions. Scarce availability of mobile money agents in the market area restricted women’s access to MFS. To bridge this gender gap and empower women entrepreneurs, we recommend Financial Institutions to Collaborate with MFS providers to offer targeted training programs. These sessions should focus on MFS awareness, digital literacy, and documentation procedures. NGOs Community Initiatives should launch awareness campaigns specifically tailored for women vendors. These campaigns can demystify MFS, emphasize its benefits, and address common concerns. By dismantling these barriers, we can unlock the full potential of MFS, enabling women entrepreneurs to thrive and contribute significantly to sustainable development in Zimbabwe.

    Midwife led maternity care models: A scoping review
    (2023) Danda, G.; Chaibva, C.N.; Chauraya, Y.; Gwatiringa, C.; Chamisa, J.A.; Dabengwa, I.M.; Moyo, H.; Mantula, F.; Sibanda, E.
    Introduction: Midwife led maternity care models focus on normality, continuity of care and being cared for by trusted midwives from preconception throughout pregnancy, labour and the postnatal period. The aim of this model is to provide care either in community or hospital settings, normally to healthy women with uncomplicated pregnancies. Methods: The scoping review used search terms for the PICO components with synonyms, related terms and specialist terms were harvested from the Medical Subject Headings (MeSH)© and Embase© using Rayyan. Database searches were from PubMed, EBSCO-CINAHL, Dimensions, Web of Science, SCOPUS, and the Cochrane Library of Systematic reviews and African Journals Online (AJOL). A total of 17 058 citations were identified and 69 remained for analysis after removing duplicates and others which did not meet the criteria. Results: Of the 69 included studies, 14 were qualitative, 34 were quantitative, 19 were RCTs and 2 were mixed methods. Only 13% of the studies were from Africa and the rest were from the developed world. Six themes emerged as follows: reduced interventions in labour; positive birth outcomes; satisfaction with care; cost effectiveness of services; autonomous practice and quality midwifery services; good woman–midwife relationship and several subthemes. Discussion: Midwife-led care had a significant positive effect on physiological outcomes for women when compared to physician-led care, had reduced surgical interventions and augmentation, as well as less usage of pharmacological analgesia. This may also assist in acceptability, accessibility and availability of such a model in all maternity care units and community settings in LMICs.

    Protocol for a scoping review to evaluate the extent of utilisation of healthcare services by asthma patients in subSaharan African countries
    (BMJ Open, 2021-10-29) Ndarukwa, P.; Chimbari, M.J.; Sibanda, E.
    Introduction Health systems in sub-Saharan African (SSA) countries are fragile and centralised. Consequently, majority of people have restricted access to healthcare services. Given the rise in the prevalence and burden of asthma in SSA, it is imperative to scrutinise the utilisation of healthcare services by people with asthma. We aim to understand, through this review, the extent of utilisation of healthcare services by asthma patients in SSA countries. Methods and analysis Arksey and O’Malley’s scoping review methodology framework will be used to guide the conduct of this scoping review. We will conduct a search of the literature on the electronic databases: Medline, (using PubMed interface), EMBASE, EBSCOHOST, Web of Science and Google Scholar, grey literature sources and the reference lists of key studies to identify studies appropriate for inclusion. Two reviewers will independently screen all abstracts and full-text studies for inclusion. Registration of the proposed scoping review on the PROSPERO has indicated that no similar work has been or is being done elsewhere. We will review studies published on the subject from January 2009 to May 2020 in SSA. Ethics and dissemination The proposed scoping review will contribute towards the knowledge base on utilisation of healthcare services particularly for people with asthma. This will provide a better understanding of the extent of utilisation of healthcare services by asthma patients and ultimately contribute to improvement of quality of care for people suffering from asthma. The results from the review will enlighten and guide healthcare practitioners and researchers on developing appropriate and feasible interventions to increase the utilisation of healthcare services by asthma patients in resource-constrained settings in SSA countries. Results of this scoping review will be disseminated through a peer-reviewed publication, conference presentations and a 1-day stakeholder meeting.

    Sensitisation to Imbrasia belina (mopane worm) and other local allergens in rural Gwanda district of Zimbabwe
    (2022) Ndlovu, V.; Chimbari, M.; Ndarukwa, P.; Sibanda, E.
    Background: The prevalence of allergic diseases is increasing in Zimbabwe and the data relate to local as well as exotic allergen sources. As entomophagy, the practice of eating insects, is a recognised source of local allergens, we sought to measure the prevalence of and risk factors for sensitisation to Imbrasia belina (mopane worm), a popular edible insect. This was investigated alongside other locally relevant allergens in a rural community in Gwanda district, south of Zimbabwe. Methods: A cross sectional study was conducted among 496 adults and children aged 10 years and above in Gwanda district, a mopane worm harvesting area in Zimbabwe. Data on individual characteristics and mopane worm exposure factors were collected using questionnaires. Sensitivity to allergens was assessed by performing skin prick tests at a local clinic using 10 different commercial allergen extracts (Stallergenes, France) and in-house extracts of mopane worm (Imbrasia belina) and mopane leaves (Colophospermum mopane). Data were analysed using Stata version 13 software. Results: The prevalence of sensitisation to at least one allergen was 31.17% (n = 144). The prevalence of atopy was higher in adults (33.33%) than in children (23.53%) (p = 0.059). The commonest inhalant allergen sources were mopane worm (14.29%), Tyrophagus putrescentiae (14.29%), mopane leaves (13.42%), Alternaria alternata (6.49%) and Dermatophagoides pteronyssinus (6.49%). Polysensitisation was demonstrated in the study population and of the 108 participants (75%) who were sensitised to two or more allergens, 66 (61%) were women. Sensitisation to mopane worm and mopane leaves often clustered with Tyrophagus putrescentiae amongst adults. Adjusted logistic regression analyses between mopane worm sensitisation and self-reported exposure variables showed that sensitisation was more likely amongst mopane worm harvesters (OR = 1.92, 95%CI = 0.77–4.79), those who cooked or roasted mopane worms during harvesting (OR = 2.69, 95%CI = 0.78–9.31) and harvesting without personal protective equipment (PPE) (OR = 2.12, 95%CI = 0.83–5.44) compared to non-harvesters. Conclusion: Atopic sensitization was common in this mopane worm harvesting community in Gwanda district of Zimbabwe. There was frequent co-sensitisation of mopane worm and mopane leaves with Tyrophagus putrescentiae in children and adults. It is important to determine the clinical relevance of our findings, particularly relating to mopane worm sensitisation.
