Current tobacco use and susceptibility to using tobacco among non-users of tobacco: A cross-sectional study among school-going adolescents in Sierra Leone.

INTRODUCTION: Tobacco use is a global health threat associated with a high disease burden and death. Current tobacco use and susceptibility to using tobacco products among adolescents who are potential adult tobacco users have not been explored in Sierra Leone. Thus, we aimed to estimate the prevalence and correlates of current tobacco use and tobacco non-users susceptibility to using tobacco amongst high school students in Sierra Leone. METHODS: We used data obtained from the 2017 Sierra Leone Global Youth Tobacco Survey (GYTS), which presented information collected from 6680 students aged 11-17 years nationwide. Gender-based correlates of current use and susceptibility to using tobacco among non-tobacco users were determined by complex sample logistic regression analyses. Adjusted odds ratios (AOR) and respective 95% confidence intervals (CIs) are reported. A p<0.05 was considered significant. RESULTS: The prevalence of current tobacco use among high school adolescents in Sierra Leone was 24.6%, higher in males (27.9%) than in females (18.6%). Male (AOR=1.50; 95% CI: 1.18-1.91), parental smoking (AOR=1.73; 95% CI: 1.32-2.26) exposure to household secondhand smoke (AOR=1.82; 95% CI: 1.27-2.62), having peers who smoke (AOR=2.24; 95% CI: 1.51-3.31) were more likely to be currently using tobacco. The overall tobacco non-users susceptibility to using tobacco among adolescents in Sierra Leone was 18.2% (males 18.0%, females 18.5%). Exposure to tobacco promotion (AOR=1.50; 95% CI: 1.06-2.10) and non-exposure to anti-smoking education (AOR=1.39; 95% CI: 1.05-1.86) were significantly associated with tobacco non-users' susceptibility to using tobacco. CONCLUSIONS: Our study suggests that one in four school-going adolescents currently uses tobacco, with nearly one in five non-users susceptible to using tobacco. Given the high prevalence of tobacco product use among adults in Sierra Leone, our findings highlight the need for policies and interventions to prevent tobacco use behavior among adolescents, aimed at averting tobacco use in adulthood.

Regulating clinical trials in a resource-limited setting during the Ebola public health emergency in Sierra Leone.

Clinical trials during public health emergencies of novel medical products such as therapeutics and vaccines in resource-limited settings are daunting due to the limited capacity for regulatory assessment. Regulating clinical trials during the Ebola outbreak in Sierra Leone required expedited evaluation to identify medical products that could be promptly introduced to combat the epidemic in the absence of approved treatment or prevention. This article explored the decisions taken by the Pharmacy Board of Sierra Leone through its Expert Committee on Medicine Safety and Clinical Trials regarding clinical trials oversight during the Ebola epidemic and the lessons learned. This independent expert committee assessed and provided scientific opinions to the Pharmacy Board of Sierra Leone to inform approval of all clinical trials within 10-15 working days. We also requested for assisted review from the African Vaccine Regulatory Forum and support from the US Food and Drug Administration through a unilateral recognition and reliance memorandum of understanding. In addition, the Agency-ensured structures and systems were in place for reporting and reviewing adverse events and serious adverse events, management of biological samples, submission and review of progress reports, and good clinical practice inspections. Unfortunately, the Ebola epidemic revealed many weaknesses in the country's clinical trials regulatory structure and processes. Government and partners should further offer more resources to build the clinical trial structures and systems so that the Agency will be better poised to handle future public health emergencies.

Awareness, use, attitude and perceived need for Complementary and Alternative Medicine (CAM) education among undergraduate pharmacy students in Sierra Leone: a descriptive cross-sectional survey.

BACKGROUND: The widespread use of CAM around the world requires health professionals including pharmacists to have the required knowledge to better advise their patients. This has lead to an increased need for the inclusion of CAM instruction into the mainstream undergraduate Pharmacy education. This study was designed to describe pharmacy students awareness, use, attitude and perceived need for CAM education at COMAHS-USL and at the same time, determine how these descriptive outcomes are influenced by the socio-demographic variables considered in this study. METHODS: A descriptive cross-sectional survey was conducted among undergraduate pharmacy students (n = 90) at the College of Medicine and Allied Health Sciences, University of Sierra Leone using a structured questionnaire. Chi square, fisher exact test, and general linear model univariate analysis were used to compare data between independent cohorts. RESULTS: All 90 (100%) of the students were aware and have used (except Ayurveda) at least one of the listed CAM modalities. Herbal/Botanical/Supplements followed by Spirituality/Prayer were the most commonly known and used CAM modalities. Almost two thirds of students considered the CAM modalities they have used to be effective and not harmful. Overall, pharmacy students had a positive attitude towards CAM (Mean attitudinal score = 34.9 ± 4. 5 (range 19-43)) with fourth and fifth year students showing a significantly less positive attitude as compared to the first, second and third year (B = -3.203 p = 0.001, 95% confidence interval -5.093 to -1.314). The media [53 (58.9%)] was the most frequent source of information about CAM. Nearly all students [89 (98.9%)] agreed that CAM knowledge is important to them as future pharmacist and that CAM should be included into the Pharmacy curriculum at COMAHS-USL [81 (90.0%)]. CONCLUSION: Pharmacy students in Sierra Leone are aware of and have used at least one of the CAM modalities and do show a positive attitude towards CAM. This was demonstrated by their overwhelming endorsement for CAM course to be part of the undergraduate pharmacy training at COMAHS-USL. This study among others will inform and guide the development and implementation of CAM instruction at COMAHS-USL.

A rapid ultra performance liquid chromatography-tandem mass spectrometric method for the qualitative and quantitative analysis of ten compounds in Eucommia ulmodies Oliv.

A rapid method for qualitative and quantitative analysis of constituents in Eucommia ulmoides Oliv. was developed by ultra performance liquid chromatography with electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS). Ten compounds including iridoids, phenylpropanoids, and flavonoids were identified and further quantified as marker substances by UPLC-UV using switching UV wavelength within 16min. The separation was carried out on an Acquity UPLC BEH C(18) column with 0.1% formic acid aqueous solution and acetonitrile as the mobile phase under gradient conditions. The developed method was applied to the quality assessment of various E. ulmoides samples, including different medicinal parts, differently processed bark and bark from different habitats. The results showed that the branches of E. ulmoides were not suitable for medicinal use. The process of carbonizing led to significant loss of major components, whereas the process of stir-frying with salt-water enhanced the extraction of chlorogenic acid with negligible loss of the other components. The contents of the investigated compounds varied very remarkably for the bark of E. ulmoides collected from different habitats. This study might provide a comprehensive method for the quality assessment of E. ulmoides.
