A Survey of Major Ethno Medicinal Plants of Kano North, Nigeria, Their Knowledge and Uses by Traditional Healers

An ethno botanical survey of major ethnomedicinal plants was carried out in the study area (Kano north senatorial district, Nigeria), their knowledge and uses by the local healers was determined. Data was obtained through the use of interviewer administered questionnaires, distributed at random to the traditional healers as the target respondents. Research shows that various plant species from 25 families were reported to be used in the treatment of various human ailments. Majority of these plants (73.2%) were wild, and 40% were harvested mainly for their leaves. Most of the plants were trees (44%). About 45.2% have been reported to be used in dry form. Concoction was the major method of preparation of the medicinal plants (46%). The most reported threat to the availability of medicinal plants was deforestation (43.6%). Many additives like edible oil, honey, butter, porridge, garlic were used in almost 58% of the remedy preparations. In addition, more than one medicinal plant species were used more frequently than the use of single species for medicinal preparations.Keywords: Ethnobotany, Senatorial zone, Knowledge, Use

Lessons from co-production of evidence and policy in Nigeria's COVID-19 response

In February 2020, Nigeria faced a potentially catastrophic COVID-19 outbreak due to multiple introductions, high population density in urban slums, prevalence of other infectious diseases and poor health infrastructure. As in other countries, Nigerian policymakers had to make rapid and consequential decisions with limited understanding of transmission dynamics and the efficacy of available control measures. We present an account of the Nigerian COVID-19 response based on co-production of evidence between political decision-makers, health policymakers and academics from Nigerian and foreign institutions, an approach that allowed a multidisciplinary group to collaborate on issues arising in real time. Key aspects of the process were the central role of policymakers in determining priority areas and the coordination of multiple, sometime conflicting inputs from stakeholders to write briefing papers and inform effective national decision making. However, the co-production approach met with some challenges, including limited transparency, bureaucratic obstacles and an overly epidemiological focus on numbers of cases and deaths, arguably to the detriment of addressing social and economic effects of response measures. Larger systemic obstacles included a complex multitiered health system, fragmented decision-making structures and limited funding for implementation. Going forward, Nigeria should strengthen the integration of the national response within existing health decision bodies and implement strategies to mitigate the social and economic impact, particularly on the poorest Nigerians. The co-production of evidence examining the broader public health impact, with synthesis by multidisciplinary teams, is essential to meeting the social and public health challenges posed by the COVID-19 pandemic in Nigeria and other countries

Limited emergence of resistance to integrase strand transfer inhibitors (INSTIs) in ART-experienced participants failing dolutegravir-based antiretroviral therapy: a cross-sectional analysis of a Northeast Nigerian cohort

Background Due to the high prevalence of resistance to NNRTI-based ART since 2018, consolidated recommendations from the WHO have indicated dolutegravir as the preferred drug of choice for HIV treatment globally. There is a paucity of resistance outcome data from HIV-1 non-B subtypes circulating across West Africa. Aims We characterized the mutational profiles of persons living with HIV from a cross-sectional cohort in North-East Nigeria failing a dolutegravir-based ART regimen. Methods WGS of plasma samples collected from 61 HIV-1-infected participants following virological failure of dolutegravir-based ART were sequenced using the Illumina platform. Sequencing was successfully completed for samples from 55 participants. Following quality control, 33 full genomes were analysed from participants with a median age of 40 years and median time on ART of 9 years. HIV-1 subtyping was performed using SNAPPy. Results Most participants had mutational profiles reflective of exposure to previous first- and second-line ART regimens comprised NRTIs and NNRTIs. More than half of participants had one or more drug resistance-associated mutations (DRMs) affecting susceptibility to NRTIs (17/33; 52%) and NNRTIs (24/33; 73%). Almost a quarter of participants (8/33; 24.4%) had one or more DRMs affecting tenofovir susceptibility. Only one participant, infected with HIV-1 subtype G, had evidence of DRMs affecting dolutegravir susceptibility—this was characterized by the T66A, G118R, E138K and R263K mutations. Conclusions This study found a low prevalence of resistance to dolutegravir; the data are therefore supportive of the continual rollout of dolutegravir as the primary first-line regimen for ART-naive participants and the preferred switch to second-line ART across the region. However, population-level, longer-term data collection on dolutegravir outcomes are required to further guide implementation and policy action across the region

Effect of Standard Tuberculosis Treatment on Plasma Cytokine Levels in Patients with Active Pulmonary Tuberculosis

CITATION: Riou, C. et al. 2012. Effect of standard tuberculosis treatment on plasma cytokine levels in patients with active pulmonary tuberculosis. PLoS ONE, 7(5): e36886, doi:10.1371/journal.pone.0036886.The original publication is available at http://journals.plos.org/plosoneBackground: Sputum Mycobacterium tuberculosis (Mtb) culture is commonly used to assess response to antibiotic treatment in individuals with pulmonary tuberculosis (TB). Such techniques are constrained by the slow growth rate of Mtb, and more sensitive methods to monitor Mtb clearance are needed. The goal of this study was to evaluate changes in plasma cytokines in patients undergoing treatment for TB as a means of identifying candidate host markers associated with microbiologic response to therapy. Methods: Twenty-four plasma cytokines/chemokines were measured in 42 individuals diagnosed with active pulmonary TB, 52% were HIV co-infected. Individuals, undergoing a 26-week standard TB treatment, were followed longitudinally over 18 months and measurements were associated with HIV status and rates of sputum culture conversion. Results: Plasma concentrations of interferon-inducible protein-10 (IP-10) and vascular endothelial growth factor (VEGF) were significantly reduced upon TB treatment, regardless of HIV status. By the end of treatment, IP-10 concentrations were significantly lower in HIV negative individuals when compared to HIV-positive individuals (p = 0.02). Moreover, in HIV negative patients, plasma VEGF concentrations, measured as early as 2-weeks post TB treatment initiation, positively correlated with the time of sputum conversion (p = 0.0017). No significant changes were observed in other studied immune mediators. Conclusions: These data suggest that VEGF plasma concentration, measured during early TB treatment, could represent a surrogate marker to monitor sputum culture conversion in HIV uninfected individuals.http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0036886Publisher's versio

The mediating effects of first call resolution on call centers’ performance

This article aims to examine and validate the prepositions of the mediating impacts of first call resolution (FCR) on caller satisfaction within the contact center industry.A survey of 168 call center managers was analyzed through structural equation modeling, constituting an overall 43.3 per cent response rate for this study.The results show that FCR positively mediates the relationship between knowledge management, technology-based CRM and caller satisfaction within the inbound customer contact centers.We have empirically assessed call centers/contact centers’ success through caller satisfaction (an observed variable through their 2009 customer survey in Malaysia).Consequently, this study cannot generalize its findings in all other countries.Our strong argument is that within the operational variables, FCR is statistically significant and positively mediates knowledge management applications. But very important to note is that the customer contact centers are first touch points to a company's goods or services, and that many other factors such as product quality, company policy, target markets, decision-making processes and so on are also determinants of caller satisfaction, but fall outside the operational control of contact center activities.This research has empirically established that a company's capability in effectively acquiring a valid understanding of its current and potential customers’ information through CRM technologies will positively impact its acquisitions, customization, management and retention of customers.It also avails both the academic and contact center management the benefits that are inherent in measuring the impact of knowledge management and technology-based CRM on inbound FCR and caller satisfaction.This study finally recommends alternative areas for future research
