    A global bibliometric analysis of research productivity on vaccine hesitancy from 1974 to 2019
    (Taylor & Francis, 2021-05) Jaca, Anelisa; Iwu-Jaja, Chinwe J.; Balakrishna, Yusentha; Pienaar, Elizabeth; Wiysonge, Charles S.
    Vaccine hesitancy is a phenomenon where individuals delay or refuse to take some or all vaccines. The objective of this study was to conduct a global bibliometric analysis of research productivity and identify country level indicators that could be associated with publications on vaccine hesitancy. We searched PubMed and Web of Science for publications from 1974 to 2019, and selected articles focused on behavioral and social aspects of vaccination. Data on country-level indicators were obtained from the World Bank. We used Spearman’s correlation and zero-inflated negative-binomial regression models to ascertain the association between country level indicators and the number of publications. We identified 4314 articles, with 1099 eligible for inclusion. The United States of America (461 publications, 41.9%), Canada (84 publications, 7.6%) and the United Kingdom (68 publications, 6.2%) had the highest number of publications. Although various country indicators had significant correlations with vaccine hesitancy publications, only gross domestic product (GDP) and gross national income (GNI) per capita were independent positive predictors of the number of publications. When the number of publications were standardized by GDP, the Gambia, Somalia and Malawi ranked highest in decreasing order. The United States, Canada and United Kingdom ranked highest (in that order) when standardized by current health expenditure. Overall, high-income countries were more productive in vaccine hesitancy research than low-and-middle-income countries. There is a need for more investment in research on vaccine hesitancy in low-and-middle-income countries.

    Reorganisation of primary care services during COVID-19 in the Western Cape, South Africa : perspectives of primary care nurses
    (AOSIS, 2021-11) Crowley, Talitha; Kitshoff, Danine; De Lange-Cloete, Frances; Baron, Justine; De Lange, Santel; Young, Cornelle; Esterhuizen, Tonya; Couper, Ian
    Background: Primary care nurses play a pivotal role in the response to disasters and pandemics. The coronavirus diseases 2019 (COVID-19) pandemic required preventative, diagnostic, and curative measures for persons presenting with symptoms of COVID-19 by healthcare providers, whilst continuing other essential services. We aimed to investigate the reorganisation of primary care services during COVID-19 from the perspectives of primary care nurses in the Western Cape province of South Africa. Methods: We administered an online survey with closed and open-ended questions to professional nurses enrolled for a Postgraduate Diploma in Primary Care Nursing at Stellenbosch University (2020) and alumni (2017–2019) working in the Western Cape. Eighty-three participants completed the questionnaire. Results: The majority of the participants (74.4%) reported that they were reorganising services using a multitude of initiatives in response to the diverse infrastructure, logistics and services of the various healthcare facilities. Despite this, 48.2% of the participants expressed concerns, which mainly related to possible non-adherence of patients with chronic conditions, the lack of promotive and preventative services, challenges with facility infrastructure, and staff time devoted to triage and screening. More than half of the participants (57.8%) indicated that other services were affected by COVID-19, whilst 44.6% indicated that these services were worse than before. Conclusion: Our findings suggest that the very necessary reorganisation of services that took place at the start of the COVID-19 pandemic in South Africa enabled effective management of patients infected with COVID-19. However, the reorganisation of services may have longer-term consequences for primary care services in terms of lack of care for patients with other conditions, as well as preventive and promotive care.

    Understanding the underlying drivers of obesity in Africa : a scoping review protocol
    (BMJ Publishing, 2020-11) Jaca, Anelisa; Iwu, Chinwe; Durão, Solange; Onyango, Adelheid W.; Wiysonge, Charles Shey
    Introduction: The worldwide prevalence of obesity and overweight has doubled since 1980, such that approximately a third of the world's population is reported as obese or overweight. Obesity rates have increased in all ages and both sexes irrespective of geographical area, ethnicity or socioeconomic status. Due to the high prevalence, related health consequences and costs of childhood and adult obesity, there is a need to comprehensively identify and assess the major underlying drivers of obesity and overweight in the African context. Methods and analysis: This scoping review will be carried out as per the methodological outline by Arksey and O'Malley. The search strategy will be developed and search performed in the Scopus and PubMed electronic databases. In the first search, we will identify concepts that are used as an equivalent to obesity and overweight. Subsequently, we will search for studies comprising of search terms on the underlying factors that drive the development of obesity and overweight. Lastly, we will check reference lists for additional publications. Abstracts and full-text studies will independently be screened by two authors. Ethics and dissemination: The proposed study will generate evidence from published data and hence does not require ethics approval. Evidence generated from this review will be disseminated through journal publications and conference presentations.

    Antimicrobial resistance phenotype of staphylococcus aureus and escherichia coli isolates obtained from meat in the formal and informal sectors in South Africa
    (ps202304, 2020-09) Jaja, Ishmael Festus; Jaja, Chinwe-Juliana Iwu; Chigor, Nnamdi Vincent; Anyanwu, Madubuike Umunna; Maduabuchi, Ezealisiji Kenneth; Oguttu, James Wabwire; Green, Ezekiel
    Background: Foodborne diseases (FBD) caused by resistant pathogens are a global public health problem. One main driver of the increasing FBD incidence is the transfer of pathogenic organisms from animal guts to carcasses during processing and subsequent transfer from meat products to consumers. Methods: In this study, meat samples from abattoirs in the formal meat sector (FMS) (n = 140) and slaughter points in the informal meat sector (IMS) (n = 104) were collected for microbial detection and phenotypic AMR determination using polymerase chain reaction. Results. The antibiogram of Staphylococcus aureus isolates revealed that resistance to clindamycin (74.3%) and ampicillin (59.5%) was highest in the FMS, while resistance to penicillin (83.8%) and tetracycline (82.1%) was highest in the IMS. Escherichia coli isolates show significant resistance to chloramphenicol (90.7%) and tetracycline (82.3%) in the FMS. Likewise, resistance to tetracycline (92.3%) and sulfamethoxazole/trimethoprim (87.5%) was highest in the IMS. The multiple antibiotic resistance index (MARI) for S. aureus and E. coli ranged from 0.3 to 0.8 and 0.2 to 0.5, respectively. Conclusion: This study suggests high-level contamination of meat with resistant pathogens and highlights the public health consequences associated with consuming such unhygienic products

    Utilisation and perceptions of cervical cancer screening services
    (Unisa Press, 2020) Kokuro, Mercy; Diji, Abigail Kusi-Amponsah
    Cervical cancer is the second most frequently diagnosed and the fourth commonest cause of cancer death among women worldwide. Even though cervical cancer is preventable, its screening rate has been reported to be low in Ghana. To the best of our knowledge, no study has focused on the utilisation and perceptions of cervical cancer among women in their reproductive age in Ghana. The present study aimed at assessing the utilisation and perceptions of cervical cancer screening services among women who seek reproductive healthcare services. A descriptive cross-sectional study was carried out among women aged 18 years and above. Using a two-stage sampling technique, 369 participants were selected from 2 out of 4 eligible study sites. Data on the perceptions and utilisation of cervical cancer screening services were collected following ethical approval. The data were collected using both English and Twi versions of the questionnaire. The data were descriptively and inferentially analysed. A few of the participants had been previously screened for cervical cancer (n = 69; 18.7%), while a greater proportion of the participants appropriately perceived the screening benefits (> 70%), and an equally greater percentage of them harboured negative perceptions which prevented them from engaging in such endeavours (> 80%). Significant differences in perception were, however, observed in two-fifths of the studied areas (6/14) among the screened and unscreened participants. Cervical cancer screening services were not utilised by the majority of the participating women. Screening was associated with socio-demographic characteristics such as marital status, parity, education, and employment status. Inappropriate perceptions on cervical cancer screening may account for the low utilisation of cervical cancer screening. Therefore, all-inclusive health education on the benefits of cervical cancer screening for both women and men should be a priority for stakeholders and all health organisations.
