Epidemiology of West Nile virus in Africa: An underestimated threat

Background West Nile virus is a mosquito-borne flavivirus which has been posing continuous challenges to public health worldwide due to the identification of new lineages and clades and its ability to invade and establish in an increasing number of countries. Its current distribution, genetic variability, ecology, and epidemiological pattern in the African continent are only partially known despite the general consensus on the urgency to obtain such information for quantifying the actual disease burden in Africa other than to predict future threats at global scale. Methodology and principal findings References were searched in PubMed and Google Scholar electronic databases on January 21, 2020, using selected keywords, without language and date restriction. Additional manual searches of reference list were carried out. Further references have been later added accordingly to experts’ opinion. We included 153 scientific papers published between 1940 and 2021. This review highlights: (i) the co-circulation of WNV-lineages 1, 2, and 8 in the African continent; (ii) the presence of diverse WNV competent vectors in Africa, mainly belonging to the Culex genus; (iii) the lack of vector competence studies for several other mosquito species found naturally infected with WNV in Africa; (iv) the need of more competence studies to be addressed on ticks; (iv) evidence of circulation of WNV among humans, animals and vectors in at least 28 Countries; (v) the lack of knowledge on the epidemiological situation of WNV for 19 Countries and (vii) the importance of carrying out specific serological surveys in order to avoid possible bias on WNV circulation in Africa. Conclusions This study provides the state of art on WNV investigation carried out in Africa, highlighting several knowledge gaps regarding i) the current WNV distribution and genetic diversity, ii) its ecology and transmission chains including the role of different arthropods and vertebrate species as competent reservoirs, and iii) the real disease burden for humans and animals. This review highlights the needs for further research and coordinated surveillance efforts on WNV in Africa.

Identifying occupational health hazards among healthcare providers and ancillary staff in Ghana: a scoping review protocol

IntroductionThe formation, modification and implementation of occupational health and safety policy for the Ghana healthcare industry hinge on data and reviews on occupational exposures. However, there is no synthesised review to speak to the issues of these occupational exposures. A scoping review on occupational exposures among the health workforce in Ghana will provide a broad overview of exposures, and can guide and assist in making decisions on occupational health issues relating to healthcare workers.Methods and analysisArksey and O’Malley’s scoping review methodology framework will guide the conduct of this scoping review. Primary research studies, government documents and other information on occupational exposures among healthcare workers published in the English language will be retrieved from databases including PubMed, CINAHL, Embase, MEDLINE, Scopus, PsycINFO and Google scholar. A systematic search strategy will be employed to identify articles from 1 January 2010 until 30 November 2021. Also, grey literature sources in Ghana including government and tertiary institutions websites will be searched. A reference list of key studies and other available non-electronic materials will also be screened to identify relevant studies for inclusion. The review will consider studies that address prevalence, knowledge and predisposing factors of occupational exposures along with the use of occupational hazards control/preventive measures. After removal of duplicates, and title and abstract screening, relevant articles will be subjected to full-text analysis. The screening processes will be conducted independently by two reviewers. Data will then be extracted and presented in tabular form with a narrative to aid easy comprehension.Ethics and disseminationThis scoping review does not require ethical approval. The findings will be disseminated through publications, conference presentations and stakeholder meetings.

What is known from the existing literature about self-management of pessaries for pelvic organ prolapse? A scoping review protocol

IntroductionPelvic organ prolapse (POP) can be managed with a pessary; however, regular follow-up may deter women from pessary management due to the inconvenience of frequent appointments, as well as preventing pessary users from autonomous decision-making. Pessary self-management, whereby the woman removes and inserts her own pessary may be a solution to these issues. However, there remains a number of uncertainties regarding the potential benefits and risks of pessary self-management. This scoping review aims to map available evidence about the subject of pessary self-management for POP to identify knowledge gaps providing the basis for future research.Methods and analysisThe scoping review will be conducted using the Joanna Briggs Institute scoping review methodology and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. A search of Medline, CINAHL, Embase and PsycInfo will be undertaken to identify relevant articles which meet the eligibility criteria using the search terms ‘pessary’ and ‘self-management’ or ‘self-care’. A hand search of the reference list of non-original research identified during the search but excluded, will be conducted for additional publications which meet the inclusion and exclusion criteria. Data relevant to the topic of pessary self-management will be extracted and critical appraisal of all included publications undertaken.Ethics and disseminationNo ethical or Health Research Authority approval is required to undertake the scoping review. However, it has been registered with The Open Science Framework (DOI 10.17605/OSF.IO/DNGCP). The findings will inform future research exploring pessary self-management and be disseminated via both a presentation at a national conference and publications in peer reviewed journals.

The relationship between mental health and risk of active tuberculosis: a systematic review

ObjectivesTuberculosis (TB) and mental illnesses are highly prevalent globally and often coexist. While poor mental health is known to modulate immune function, whether mental disorders play a causal role in TB incidence is unknown. This systematic review examines the association between mental health and TB disease risk to inform clinical and public health measures.DesignSystematic review, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.Search strategy and selection criteriaMEDLINE, PsycINFO and PsycEXTRA databases were searched alongside reference list and citation searching. Inclusion criteria were original research studies published 1 January 1970–11 May 2020 reporting data on the association between mental health and TB risk.Data extraction, appraisal and synthesisData were extracted on study design and setting, sample characteristics, measurement of mental illness and TB, and outcomes including effect size or prevalence. Studies were critically appraised using Critical Appraisal Skills Programme (CASP) and Appraisal Tool for Cross-Sectional Studies (AXIS) checklists.Results1546 records published over 50 years were screened, resulting in 10 studies included reporting data from 607 184 individuals. Studies span across Asia, South America and Africa, and include mood and psychotic disorders. There is robust evidence from cohort studies in Asia demonstrating that depression and schizophrenia can increase risk of active TB, with effect estimates ranging from HR=1.15 (95% CI 1.03 to 1.28) to 2.63 (95% CI 1.74 to 3.96) for depression and HR=1.52 (95% CI 1.29 to 1.79) to RR=3.04 for schizophrenia. These data align with evidence from cross-sectional studies, for example, a large survey across low-income and middle-income countries (n=242 952) reports OR=3.68 (95% CI 3.01 to 4.50) for a depressive episode in those with TB symptoms versus those without.ConclusionsIndividuals with mental illnesses including depression and schizophrenia experience increased TB incidence and represent a high-risk population to target for screening and treatment. Integrated care for mental health and TB is needed, and interventions tackling mental illnesses and underlying drivers may help reduce TB incidence globally.PROSPERO registration numberCRD42019158071.

Paediatric Multiple Sclerosis: A Scoping Review of Patients’ and Parents’ Perspectives

Dealing with paediatric-onset multiple sclerosis is particularly challenging for the young patients and their families, due to its unpredictable symptoms and uncertain outcome. This review aimed at synthesising the qualitative evidence regarding the perspectives about paediatric-onset multiple sclerosis, as expressed by the patients and/or their parents. A literature search was conducted on PubMed and CINAHL. The advanced multi-field search allowed to perform an abstract/title search in both databases, using keywords, combined through Boolean operators. Additional search strategies were adopted: searching the reference list of the selected papers; searching for key authors in the field. All the relevant papers were thoroughly revised using The Joanna Briggs Institute’s data extraction form for qualitative evidence as a guidance. Eight papers were selected. The analysis of these papers allowed to identify some common issues pertaining paediatric-onset multiple sclerosis: (1) onset of symptoms, (2) diagnostic process, (3) reaction to the diagnosis, (4) management and acceptance of multiple sclerosis. The burden of multiple sclerosis was confirmed. However, the young patients and their parents can adjust to the disease. Both the community and the health care professionals must strive to prevent the families dealing with multiple sclerosis from experiencing solitude and rejection.

Lumbo-Pelvic and Lower Limb Joint Kinematics in Subjects with and Without Low Back Pain: A Protocol for Systematic Review

Background Low back pain (LBP) is one of the leading causes of disability worldwide. While its main cause is mostly unknown, more than 80% of people experience this disorder during their lifetime .Some clinical evidence suggests that people with chronic LBP have various lower extremity movement disorders. This study aims to systematically review the literature on comparing the kinematics of the lumbopelvic region and lower limb joints in people with non-specific low back pain (NS-LBP) compared to healthy individuals. Methods/design: We will search main electronic databases (Medline/PubMed, Scopus, Embase, Web of Science, Pedro, ProQuest and Google Scholar) and two key journals (Journal of Electromyography and Kinesiology, Clinical Biomechanics). Also, the reference list of the previous systematic reviews would be hand-searched. Studies that have examined the kinematic differences in lumbopelvic or lower limbs between NS-LBP and healthy individuals will be included. We will examine the methodological quality and statistical reporting of each eligible trial using the Newcastle – Ottawa Scale (NOS). Discussion To our knowledge, this study will be the first systematic review to examine the kinematic differences of the lower limb joints and pelvic complex between healthy people and NS-LBP. Since the kinematic assessment of the lower extremities and pelvic joints during daily activities may help understand underlying factors causing LBP, it is important to evaluate the kinematic changes in these regions, during repetitive daily functions in these patients.

Essential Academic Journals Tend to Be of Universal Importance, While Many Journals Available on For-Profit Platforms Appear to Be Ancillary

A Review of: Mongeon, P., Siler, K., Archambault, A., Sugimoto, C. R., & Larivière, V. (2021). Collection development in the era of big deals. College & Research Libraries, 82(2), 219–236. https://doi.org/10.5860/crl.82.2.219 Abstract Objective – (1) Present a method of journal appraisal that combines reference list, article download, and survey data. (2) Gauge journal usage patterns across selected universities. Design – Analysis of reference lists, article downloads, and survey data. Setting – 28 Canadian universities. Subjects – 47,012 distinct academic journal titles. Methods – Download data for the 2011-2015 period was sourced from standard Journal Report 1 (JR1) usage reports as supplied by the vendors. Download figures were summed for journals that were available through multiple platforms. Reference list data (i.e., the number of times documents published in each journal were cited by authors affiliated with a participating institution) was sourced from Clarivate Analytics’ Web of Science, limiting for the years 2011-2015. An unknown number of researchers at 23 of the 28 participating universities were invited by email to complete a survey. The survey asked respondents to list the scholarly journals they considered essential for their research and teaching (up to 10 journals for each purpose). The three datasets (download, reference list, and survey data) were then merged. Duplicates and non-academic journals were removed. Journals were then grouped into broad discipline areas. A list of “core journals” (p. 228) was created for each institution. These journals produce 80% of downloads, 80% of citations, or 80% of survey mentions at each institution. A journal only had to reach the threshold in one category (i.e., in either downloads, citations, or mentions) to make it onto the core journals list. A “low” (p. 228) survey response rate meant “one mention [was] generally enough" (p. 228) for a journal to be classified as core. Main results – Fewer than 500 titles (n=484, ~1%) made it to the core journals list at all 28 universities. Two thirds (66%, n unknown) of journals did not make it onto the core list of any university. Of the journals deemed to be core, most (60%, n unknown) were shared across all institutions. On average, platforms from not-for-profit organizations and scientific societies contain a higher proportion of core journals than for-profit platforms. Notably, 63.6% of Springer journals, 58.9% of Taylor & Francis journals, and 45.8% of Elsevier’s journals do not appear on the core journal list of any university. Conclusion – Libraries should consider ways to share resources and work more cooperatively in their negotiations with publishers. Further, libraries may be able to cancel entire journal bundles without this having a “sizable” (p. 233) impact on resource access.

Heterogeneity in outcome assessment for inflammatory bowel disease in routine clinical practice: a mixed-methods study in a sample of English hospitals

ObjectivesKnowledge of the extent of variation in outcome assessment for inflammatory bowel disease (IBD) in routine practice is limited. We aimed to describe and quantify variation in outcome coverage and to explore patient, clinician and practitioner factors associated with it.DesignProspective exploratory mixed-methods study.SettingIBD clinics at six hospitals in North West England with differing electronic health record (EHR) systems.MethodsMixed-methods study comprising: (a) structured observations of outcomes elicited during consultations (102 patients consulting 24 clinicians); (b) retrospective analysis of outcomes recorded in the EHR (909 consultations; 127 clinicians) and (c) semistructured interviews with the 24 observed clinicians. We determined whether specific outcome ‘sets’ were elicited or recorded, including: (1) a minimum set of symptom pairs (‘PRO-2’); (2) symptom sets from disease activity indices and (3) a reference list of 37 symptoms, signs and impacts. Factors associated with variation were explored in univariate and multivariate binary logistic regression analyses and from clinician interviews.ResultsPRO-2 coverage was not invariable (elicited during 81% of observed consultations; recorded in 56% of EHR) and infrequent for complete activity indices (all domains from Harvey-Bradshaw Index: elicited, 18%; recorded, 5%). The median number of outcomes from the reference list elicited per consultation was 12 (13-fold variation) and recorded in EHR was 7 (>20-fold variation). Symptom quantification (PRO-2) seldom adhered closely to standardised descriptors and an explicit timeframe was defined rarely. PRO-2 recording in EHR was associated with a diagnosis of ulcerative colitis (OR: 2.09 (95% CI 1.15 to 3.80)) and nurse-led consultations (OR: 6.98 (95% CI 3.28 to 14.83)) and a three-way model suggested 26% of total variability lay between clinicians, 17% between patients but the remainder was unexplained. Most clinicians expressed preference for individualised health status evaluations versus standardised outcome assessments.ConclusionsThere was little evidence for standardised assessment and recording of IBD outcomes and substantial intra-clinician and inter-clinician variation from one consultation to another. Nurses demonstrated a greater tendency to standardised practice.
