    The aim of this study was to evaluate the effects of ethanolic extract of the leaf of Azadirachta indica on haematological indices of rats. Twenty four adult male rats (weighing between 100 and 120g) were randomly but equally divided into four groups of six rats per group. Rats in group I (control) were administered with 10ml/kg of distilled water while rats in groups2 to 4 were respectively administered with the extract of A. indica orally at the dose levels of 100mg/kg, 200mg/kg and 300mg/kg, once daily for 14 days. On the 15th day post administration, rats of all the groups were sacrificed and their blood samples were collected through cardiac puncture into EDTA sample bottles for haematological analysis.The results showed that PCV, Hb, RBC counts were non-significantly increased in all the experimental groups compared to control, indicating that extract of A. Indica caused non-significant increase in thePCV, Hb and RBC counts. The mean white blood cell and platelet counts were significantly decreased in group3 compared to control. The mean lymphocyte values increased while the mean neutrophil values decreased in all the experimental groups compared to control. The mean values of MCH, MCHC and MCV were similar between experimental groups and the control. Therefore, in conclusion low dose of ethanolic Azadirachta indica causes increase in the cellular components of blood but higher dosesmay result in decrease of some or all of these blood parameters

    Using and improving the PHISICC paper-based tools in the health facility laboratories: examples of Human Centered Design taking systems thinking into practice, in CĂŽte d'Ivoire and Nigeria

    BackgroundHealth workers in low- and middle-income countries are increasingly demanded to collect more and more data to report them to higher levels of the health information system (HIS), in detriment of useful data for clinical and public health decision-making, potentially compromising the quality of their health care provison. In order to support health workers' decision-making, we engaged with partners in CĂŽte d'Ivoire, Mozambique and Nigeria in a research project to conceive, design, produce, implement and test paper-based health information tools: the PHISICC tools. Our aim was to understand the use of PHISICC tools by health workers and to improve them based on their feedback.MethodsThe design Health Facility Laboratories (HF Labs) in CĂŽte d'Ivoire and in Nigeria were set up after months of use of PHISICC tools. Activities were structured in three phases or 'sprints' of co-creative research. We used a transdisciplinary approach, including anthropology and Human Centered Design (HCD), observations, shadowing, structured interviews and co-creation.ResultsHealth workers appreciated the standardization of the tools across different health care areas, with a common visual language that optimized use. Several design issues were raised, in terms of formats and contents. They strongly appreciated how the PHISICC registers guided their clinical decision-making and how it facilitated tallying and counting for monthly reporting. However, adherence to new procedures was not universal. The co-creation sessions resulted in modifications to the PHISICC tools of out-patient care and postnatal care.DiscussionAlthough health systems and systemic thinking allowed the teams to embrace complexity, it was the HCD approach that actually produced a shift in researchers' mind-set: from HIS as data management tools to HIS as quality of care instruments. HCD allowed navigating the complexity of health systems interventions due to its capacity to operate change: it not only allowed us to understand how the PHISICC tools were used but also how to further improve them. In the absence of (or even with) an analytical health systems framework, HCD approaches can work in real-life situations for the ideation, testing and implementation of interventions to improve health systems and health status outcomes

    Harnessing the potential of African youth for transforming health research in Africa

    Africa faces a significant burden of infectious diseases, including Malaria and HIV/AIDS, along with an increasing prevalence of non-infectious diseases such as diabetes and cancer. This dual health challenge is amplified by socioeconomic difficulties, restricted access to healthcare, and lifestyle changes, thus present unique scientific needs. Effectively addressing these issues requires a skilled scientific workforce adept in comprehensive healthcare strategies. This analysis explores the critical landscape of health research in Africa, emphasizing the unique opportunity presented by the continent’s youthful population, projected to reach almost 1 billion by 2050. The youth’s innovative potential and fresh perspectives offer a chance to overcome development barriers in health research. Nevertheless, challenges such as under-resourced education, limited research training, inadequate mentorship, and funding difficulties persist. This paper urgently calls upon African leaders, international partners, and stakeholders to prioritize health research, mobilize funding, forge strategic partnerships, and empower the youth as essential steps to capitalize on the continent’s dynamic youth for breakthrough health outcomes. Such investments are vital not just for health but for the overall economic, social, and strategic growth of the continent. Through shared responsibility and a united effort, the potential of African youth can be harnessed, leading to transformative research, improved health outcomes, and a prosperous future. This perspective represents the collective voice of passionate young researchers and advocates across Africa, calling for a new era of health research on the continent

    Does an innovative paper-based health information system (PHISICC) improve data quality and use in primary healthcare? Protocol of a multicountry, cluster randomised controlled trial in sub-Saharan African rural settings

    INTRODUCTION: Front-line health workers in remote health facilities are the first contact of the formal health sector and are confronted with life-saving decisions. Health information systems (HIS) support the collection and use of health related data. However, HIS focus on reporting and are unfit to support decisions. Since data tools are paper-based in most primary healthcare settings, we have produced an innovative Paper-based Health Information System in Comprehensive Care (PHISICC) using a human-centred design approach. We are carrying out a cluster randomised controlled trial in three African countries to assess the effects of PHISICC compared with the current systems. METHODS AND ANALYSIS: Study areas are in rural zones of CĂŽte d'Ivoire, Mozambique and Nigeria. Seventy health facilities in each country have been randomly allocated to using PHISICC tools or to continuing to use the regular HIS tools. We have randomly selected households in the catchment areas of each health facility to collect outcomes' data (household surveys have been carried out in two of the three countries and the end-line data collection is planned for mid-2021). Primary outcomes include data quality and use, coverage of health services and health workers satisfaction; secondary outcomes are additional data quality and use parameters, childhood mortality and additional health workers and clients experience with the system. Just prior to the implementation of the trial, we had to relocate the study site in Mozambique due to unforeseen logistical issues. The effects of the intervention will be estimated using regression models and accounting for clustering using random effects. ETHICS AND DISSEMINATION: Ethics committees in CĂŽte d'Ivoire, Mozambique and Nigeria approved the trials. We plan to disseminate our findings, data and research materials among researchers and policy-makers. We aim at having our findings included in systematic reviews on health systems interventions and future guidance development on HIS. TRIAL REGISTRATION NUMBER: PACTR201904664660639; Pre-results

    Experiential learning and the acquisition of managerial tacit knowledge

    Get PDF
    Tacit knowledge is believed to be one factor that distinguishes successful managers from others. We sought to determine whether levels of accumulated managerial tacit knowledge (LAMTK) were associated with managers' dominant learning styles. Instruments used in the study, involving 356 Malaysian public sector employees, included Sternberg et al.'s (2000) Tacit Knowledge Inventory for Managers and a normative version of Kolb's (1999a) Learning Styles Inventory (LSI-Ill). Findings suggest that LAMTK is independent of the length of subjects' general work experience, but positively related to the amount of time spent working in a management context. Learning styles also had a significant relationship. Subjects who spent most of their time performing management functions and whose dominant learning styles were accommodating had significantly higher LAMTK than those with different learning styles. We also found support for the belief that learners with a strong preference for all four different abilities defined in Kolb's learning theory may be critical for effective experiential learning

    This paper discusses multidisciplinary international research collaboration team formation during the COVID-19 pandemic, challenges faced, strategies adopted, achievements and dynamics in the implementation of research on Coronavirus disease-2019 (COVID-19), by the African Translational Research Group (ATReG). The paper also discusses the lessons learnt and future opportunities for global collaborative research. In-depth virtual interviews were conducted with consenting members of ATReG. Questions were designed to provide rich, deep, and insightful opinions, lived experiences and perspectives of ATReG group members on group formation, challenges, strategies and achievements. Interview data was transcribed and analysed thematically, and the results were presented with important quotations presented. The ATReG consisted of English (n = 13) and French (n = 1) speaking sub-Saharan African (SSA) researchers who specialise in public health, epidemiology, optometry, information technology, supply chain management, psychiatry, community health, general medical practice, nutrition and biostatistics. Most members of the group reported an informal but well-coordinated structure of the group. Formed during the pandemic, all group meetings were held online, and many members are yet to meet each other in person. The group collected data from Africans and published 10 peer reviewed journal articles on COVID-19 within two years. It presented in international conferences, engaged with the media and the public and was awarded a national competitive funding in Nigeria all of which which contributed to career progression and academic promotion of some members. There have been challenges in sustaining the research collaboration and maintaining productivity. Challenges include difficulties meeting deadlines and obtaining funding for research activities. However, these challenges have been addressed through a collaborative problem-solving approach. The study found the need for operational and methodological flexibility, centralised coordination, and established funding sources as being essential for long term sustainability and performance of the group. The ATReG’s objective of providing useful data on COVID-19 and generating useful knowledge about COVID-19 in SSA has been achieved. In such a multi-disciplinary international collaborative team relaiant on the online medium to operate, the experiences and challenges can be a model for learning for researchers intending to form international multidisciplinary collaborative groups. Nonetheless, there are still many important areas of research which ATReG will continue to pursue

    The influence of learning styles on knowledge acquisition in public sector management

    This research note outlines a project designed to investigate the role of training institutions in providing effective training and development programmes for managers. The investigation is being carried out in the light of recent criticisms levelled against the nature of formal learning environments prevalent in most institutional settings. The traditional role of trainers and developers as the providers of knowledge and skills for the development of competent managers runs contrary to recent findings, which suggest that managers learn more effectively in informal settings, rather than the formal settings evident in many development programmes. The idea that explicitly extracted competencies are the target every manager should aim for to improve their effectiveness is also challenged because competencies alone are no longer regarded as a sufficient criterion for success. Recent research has attached greater importance to the need for helping managers to see knowledge as a social phenomenon, and one factor that might distinguish successful managers from others is tacit knowledge (Wagner & Sternberg, 1987; Argyris, 1999). A major focus of this study is to explore the possibility that the level and content of tacit knowledge acquired by managers may be influenced by their individual learning styles, and the degree to which their dominant styles are matched with the context of their work environment
