Ukrainian healthcare providers under siege during the first year of war: challenges and adaptations.

The overlapping COVID-19 crisis and the war starting in 2022 threaten front-line healthcare workers' mental health, well-being and job retention in Ukraine. This paper provides a synopsis of a panel discussion held by the Global Mental Health Humanitarian Coalition in May 2022 and expert consultations with clinicians between December 2022 and February 2023 on these challenges. The crises created new problems and exacerbated many pre-existing difficulties. We found that healthcare workers had needed to mobilise previously untapped strengths, including portable emergency medical documents and bespoke local psychosocial support services, amid the costs and pressures of ongoing healthcare reforms.

Trends in Adverse Event Reporting Before and After the Introduction of the Med Safety App in Nigeria.

INTRODUCTION: Spontaneous reporting of adverse events (AEs) is a mainstay of pharmacovigilance, and an ongoing challenge is how to ensure that more high-quality reports are collected for comprehensive information provision. The Med Safety App, a smartphone-based application, was launched in Nigeria in November 2020 to provide an electronic platform for users to seamlessly report AEs. There has been a paucity of evidence on the use of this application or other mobile applications for reporting adverse drug reactions/AEs following immunization in the Nigerian environment. OBJECTIVE: The aim of this study was to evaluate the trends in adverse event reporting before and after the introduction of the Med Safety App in Nigeria. METHODS: This was a retrospective, observational study using data from the VigiFlow database to compare adverse event reporting in Nigeria before and after the deployment of the Med Safety App. The baseline period was 1st April 2019 to 30th October 2020 and the comparison period was 1st November 2020 to 31st May 2022. We used Vigilance Hub, the back-end system for the Med Safety App, to extract data on App downloads and de-identified user statistics. Data were summarized using descriptive statistics, frequencies and proportions. Quality was assessed by assigning a completeness score to each individual case safety report. The Kruskal-Wallis test was used to test for differences in medians between groups. RESULTS: Following deployment of the App, the Nigerian National Pharmacovigilance Centre recorded an increase in the total number of adverse event reports received in VigiFlow, from 2051 in the baseline period to 18,995 following deployment of the App, with 81.7% of those reported via the Med Safety App. There was a reduction in the proportion of paper-based reporting from 98.4 to 15.7% post-deployment, and direct reporting by consumers increased from 2.7 to 17.6%. Of the 15,526 reports submitted via the App, 15,111 (97.3%) had a completeness score above 70% and 6993 (45%) had a completeness score of 100%. The median completeness score of adverse event reports on the Med Safety App was 6 out of 7. On bivariate analysis using the Kruskal-Wallis test, there was an association between means of reporting and completeness score, and this association was significant, with a p value of 0.0001, which may reflect the validation rules that are applied within the App. CONCLUSION: Deployment of the Med Safety App increased both the number and quality of adverse event reports; however, more awareness and capacity building are needed to strengthen and sustain reporting on the tool by all categories of healthcare professionals and consumers/patients.

Treatment System Adaptations during War: Lessons from Ukrainian Addiction Treatment Providers.

Background: The war in Ukraine has posed significant challenges to the healthcare system. This paper draws upon expert consultations, held between December 2022 and February 2023, focused on HIV/AIDS, addiction, and mental health service delivery during the first year of this war, and following the Global Mental Health Humanitarian Coalition panel discussion in May 2022. Objectives: This commentary presents the experiences of frontline healthcare workers in Ukraine, challenges, and local adaptations to meet the increased mental health needs of healthcare providers. We aimed to document the adaptations made in the addiction healthcare system and to acknowledge the changes in vulnerabilities and lessons learned. Results: Burnout among healthcare providers delivering addiction, HIV/AIDS and mental health services became more visible after the second half of 2022. Challenges included increased workload, contextual threats, lack of job relocation strategies, and money-follow-the-patient policies. Recommendations: The lessons from the first year of war in Ukraine hold significant generalizability to other contexts. These include enabling bottom-up approaches to tailoring services and allowing healthcare providers to respond to the dynamics of war in an effective and active manner. Other recommendations include departmental-specific resources and strategies, particularly as vulnerable groups and challenges are unstable in humanitarian contexts. Conclusions: Globally and in Ukraine, healthcare workers need more than applause. Along with monetary incentives, other strategies to prevent burnout, ensure sustainable capacity building, job relocation opportunities, and bespoke adaptations are imperative to protect healthcare providers' wellbeing and overall public health.

Attenuation of hyperglycemia-associated dyslipidemic, oxidative, cognitive, and inflammatory crises via modulation of neuronal ChEs/NF-κB/COX-2/NOx, and hepatorenal functional deficits by the Tridax procumbens extract.

Tridax procumbens (cotton buttons) is a flowering plant with a medicinal reputation for treating infections, wounds, diabetes, and liver and kidney diseases. The present research was conducted to evaluate the possible protective effects of the T. procumbens methanolic extract (TPME) on an experimentally induced type 2 diabetes rat model. Wistar rats with streptozotocin (STZ)-induced diabetes were randomly allocated into five groups of five animals each, viz., a normal glycemic group (I), diabetic rats receiving distilled water group (II), diabetic rats with 150 (III) and 300 mg/kg of TPME (IV) groups, and diabetic rats with 100 mg/kg metformin group (V). All treatments were administered for 21 consecutive days through oral gavage. Results: Administration of the T. procumbens extract to diabetic rats significantly restored alterations in levels of fasting blood glucose (FBG), body weight loss, serum and pancreatic insulin levels, and pancreatic histology. Furthermore, T. procumbens significantly attenuated the dyslipidemia (increased cholesterol, low-density lipoprotein-cholesterol (LDL-C), triglycerides, and high-density lipoprotein (HDL) in diabetic rats), serum biochemical alterations (alanine transaminase (ALT), aspartate transaminase (AST), alanine phosphatase (ALP), blood urea nitrogen (BUN), creatinine, uric acid, and urea) and full blood count distortion in rats with STZ-induced diabetes. The TPME also improved the antioxidant status as evidenced by increased superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and decreased malondialdehyde (MDA); and decreased levels of cholinesterases (acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)), and proinflammatory mediators including nuclear factor (NF)-κB, cyclooxygenase (COX)- 2, and nitrogen oxide (NOx) in the brain of rats with STZ-induced diabetes compared to rats with STZ-induced diabetes that received distilled water. However, TPME treatment failed to attenuate the elevated monoamine oxidases and decreased dopamine levels in the brain of rats with STZ-induced diabetes. Extract characterization by liquid chromatography mass spectrometry (LC-MS) identified isorhamnetin (retention time (RT)= 3.69 min, 8.8%), bixin (RT: 25.06 min, 4.72%), and lupeol (RT: 25.25 min, 2.88%) as the three most abundant bioactive compounds that could be responsible for the bioactivity of the plant. In conclusion, the TPME can be considered a promising alternative therapeutic option for managing diabetic complications owing to its antidiabetic, antihyperlipidemic, antioxidant, and anti-inflammatory effects in rats with STZ-prompted diabetes.

Drug leads agents from methanol extract of Nigerian bee (Apis mellifera) propolis.

BACKGROUND: Propolis is a bee (Apis mellifera) product of plant origin with varied chemical composition depending on the ecology of the botanical origin. It has been reported in literature to possess various therapeutic effects both traditionally, clinical trial, and animal study. OBJECTIVES: In the present study bioactive principle in methanol extract of Nigerian bee (A. mellifera) propolis was determined by gas chromatography-mass spectrometry (GC/MS) study. MATERIALS AND METHODS: The methanol extract of Nigerian bee (A. mellifera) propolis was characterized for its chemical composition by preliminary phytochemicals screening and GC/MS analysis using standard procedures and methods. RESULTS: Phytochemical screening revealed the presence of flavonoids, saponins, alkaloids, tannins, cardiac glycosides, anthraquinones phlobatannins, and steroids while GC/MS chromatogram revealed nineteen peaks representing 60 different chemical compounds. The first compounds identified with less retention time (RT) (13.33s) were methyl tetradecanoate, tridecanoic acid, methyl ester, decanoic acid, methyl ester while squalene, all-trans-squalene, 2,6,10-dodecatrien-1-ol, 3,7,11-trimethyl-, (E,E)- and farnesol isomer a took longest RT (23.647s) to identify. Methyl 14-methylpentadecanoate, hexadecanoic acid methyl ester, methyl isoheptadecanoate, and methyl tridecanoate were the most concentrated constituent as revealed by there peak height (26.01%) while eicosanoic acid was the least concentrated (peak height 0.81%) constituent of Nigerian bee propolis. CONCLUSION: The presence of these chemical principles is an indication that methanol extract of Nigeria bee propolis, if properly screened could yield a drug of pharmaceutical importance.

Vision Screening to Detect Efractive Errors in Three Selected Secondary Schools in Birnin Kebbi; North West; Nigeria

Objective: The objective of this study was to determine the prevalence of uncorrected refractive error among students in three selected secondary schools in Birnin Kebbi metropolis as many children with poor vision due to refractive error remain undiagnosed and perform poorly in schools. Materials and Methods: This was a cross-sectional study that was conducted over a period of 2 months (May-June 2014). A total of 614 students were included from three randomly chosen secondary schools in Birnin Kebbi; Nigeria. Subjects were selected using random sampling technique from the list of students available through the help of their class teachers. Visual acuity (VA) was measured with a Snellen chart; while students with subnormal vision (VA = 6/9) were examined using pinhole; and subsequently referred for detailed eye examination and retinoscopy evaluation. Results: The age range was from 11 to 20 years comprising 50.8 (n = 312) males and 48.2 (n = 302) females. Refractive error in either eye was present in 30 (4.8) children. Of these; myopia was diagnosed in 18 (60) children; and then hyperopia in 7 (23.3); and astigmatism in 5 (16.7) subjects. Spectacle coverage was low as only three pupils were found to be using glasses with lack of awareness and lack of access to eye care services as major barriers. Conclusions: Uncorrected refractive error is found among secondary schools students in Birnin Kebbi; and there is a need for the establishment of regular and effective school vision screening program to detect and refer patients for treatment
