Mpox vaccine acceptance among healthcare workers: a systematic review and meta-analysis.

INTRODUCTION: Mpox is a zoonotic viral disease that emerged in May 2022 and has since shown a high prevalence in non-mpox-endemic areas, resulting in an outbreak that caused more than 84,000 cases in 110 countries around the globe. Several vaccines are available to prevent the disease, and multiple studies have been conducted to assess the attitudes of different populations toward receiving the mpox vaccine. This study systematically reviews all the studies conducted on mpox vaccine acceptance/hesitancy among healthcare workers. METHODS: A systematic literature search was conducted through four electronic databases, including PubMed, Scopus, Web of Science, and Google Scholar, up to March 2023. Studies that described mpox vaccine acceptance/hesitancy among healthcare workers were included, and the data were extracted using a uniform extraction sheet. Following the extraction, the meta-analysis included ten studies with 7322 healthcare workers. Three researchers independently assessed the risk of bias in the included study using the Newcastle-Ottawa Scale (NOS). RESULTS: Ten studies were included in the review. This review indicates that the prevalence of mpox vaccine acceptance was 58.5%, and the prevalence of mpox vaccine hesitancy was 41.5%. There was a higher prevalence of acceptance in countries located in Asian and African areas compared to those in North America and Europe, estimated at 68% and 44.3%, respectively. Among the studies conducted solely among physicians, there was a high prevalence of mpox vaccine acceptance, at 77.1%, compared to 49% in studies that included all healthcare workers. CONCLUSION: There is a significant variation in the prevalence of mpox vaccine acceptance among different populations. Further research is needed to identify the factors that contribute to this variation and to develop interventions to increase vaccine acceptance. In addition, it is important to promote research on mpox vaccine acceptance and hesitancy among healthcare workers in countries where data is limited. This research will help policymakers develop effective policies to increase acceptance and reduce the disease burden.

Characteristics of the clinical and global neurosurgical research publications from Africa: A scoping review.

Introduction: Scientific research has a direct, profound impact on healthcare systems worldwide. While an upward trend can be observed in the number of produced papers in the neurosurgical specialty, disparities still exist between African neurosurgeons on one side and between African neurosurgeons and neurosurgeons from high income countries, on the other. Research question: This study aims to analyze neurosurgical research produced in Africa to identify gaps in the literature and provide recommendations for aspiring African neurosurgeons for essential research areas. Materials and methods: Four electronic databases (PubMed, Scopus, Web of Science, and Embase) were systematically searched for relevant articles on neurosurgery published by African authors. The three main inclusion criteria were: Articles published in the Neurosurgical field, articles published by African authors (whether first authors or co-authors) and articles published in Africa. Data extracted included the study design, scope, neurosurgical subspecialty, and the authors' nationalities. Results: A total of 982 articles were included in the analysis. Of these articles, 889 (90.6%) were primary, 48 (4.9%) secondary, and 44 (4.5%) other types of research. Global Neurosurgery papers represent 7% of African neurosurgery research output. Most common primary studies included retrospective cohort (32.4%), case reports (28.3%), and prospective cohort (13.8%) studies. The most common secondary research articles were literature reviews (4.9%), letters to the editor (1.2%), and systematic reviews and meta-analyses (0.8%). Common research areas were neuro-oncology 242 (24.7%), spinal surgery 157 (16%), and cerebrovascular (14%). The most common nationalities of the first authors were Egyptian (32.4%), Moroccan (15%), and Nigerian (14.2%). Discussion and conclusion: This study identifies increased African authorship in neurosurgical research in recent years. Nevertheless, many countries still lack representation in the neurosurgical research scene.Furthermore, a high percentage of the published papers is of low evidence. Therefore, we recommend that African neurosurgical researchers focus more on clinical trials and systematic reviews that directly translate to improving clinical practice. African neurosurgeons should also consider more collaboration between African authors.

Conventional anatomical landmark versus preprocedural ultrasound for thoracic epidural analgesia: A systematic review and meta-analysis.

BACKGROUND: Thoracic epidural analgesia is the gold standard for major thoracic and abdominal surgeries. AIM: Ultrasound-guided and landmark-based thoracic epidural insertion are compared in this systematic review. METHODS: Randomised controlled trials were sought in six databases for a systematic review and meta-analysis. With a 95% confidence interval, a fixed-effects model calculated risk ratio or mean difference. Cochrane risk of bias assessed bias. Four randomised controlled trials were examined. FINDINGS: Preprocedural ultrasound increased thoracic epidural placement first-puncture success rate (risk ratio = 1.28, 95% confidence interval (1.05 to 1.56), p value = 0.02) and decreased the need for two or more skin punctures (mean difference = -2.41, 95% confidence interval (-3.34 to -1.47), p value = 0.00001). The ultrasound group reduced needle redirections (risk ratio = 0.6, 95% confidence interval (0.38 to 0.94), p value = 0.02). The epidural block success rate was equal in both groups (risk ratio = 1.02, 95% confidence interval (0.96 to 1.07), p value = 0.6). CONCLUSION: Thoracic epidural insertion is improved by ultrasound but not the success rate. Quality research with larger samples is needed to emphasise these conclusions.

Surfactant replacement therapy as promising treatment for COVID-19: an updated narrative review.

Patients with COVID-19 exhibit similar symptoms to neonatal respiratory distress syndrome. SARS-CoV-2 spike protein has been shown to target alveolar type 2 lung cells which synthesize and secrete endogenous surfactants leading to acute respiratory distress syndrome in some patients. This was proven by post-mortem histopathological findings revealing desquamated alveolar type 2 cells. Surfactant use in patients with COVID-19 respiratory distress syndrome results in marked improvement in respiratory parameters but not mortality which needs further clinical trials comparing surfactant formulas and modes of administration to decrease the mortality. In addition, surfactants could be a promising vehicle for specific drug delivery as a liposomal carrier, which requires more and more challenging efforts. In this review, we highlight the current reviews and two clinical trials on exogenous surfactant therapy in COVID-19-associated respiratory distress in adults, and how surfactant could be a promising drug to help fight the COVID-19 infection.

Examination of sleep in relation to dietary and lifestyle behaviors during Ramadan: A multi-national study using structural equation modeling among 24,500 adults amid COVID-19.

Background: Of around 2 billion Muslims worldwide, approximately 1.5 billion observe Ramadan fasting (RF) month. Those that observe RF have diverse cultural, ethnic, social, and economic backgrounds and are distributed over a wide geographical area. Sleep is known to be significantly altered during the month of Ramadan, which has a profound impact on human health. Moreover, sleep is closely connected to dietary and lifestyle behaviors. Methods: This cross-sectional study collected data using a structured, self-administered electronic questionnaire that was translated into 13 languages and disseminated to Muslim populations across 27 countries. The questionnaire assessed dietary and lifestyle factors as independent variables, and three sleep parameters (quality, duration, and disturbance) as dependent variables. We performed structural equation modeling (SEM) to examine how dietary and lifestyle factors affected these sleep parameters. Results: In total, 24,541 adults were enrolled in this study. SEM analysis revealed that during RF, optimum sleep duration (7-9 h) was significantly associated with sufficient physical activity (PA) and consuming plant-based proteins. In addition, smoking was significantly associated with greater sleep disturbance and lower sleep quality. Participants that consumed vegetables, fruits, dates, and plant-based proteins reported better sleep quality. Infrequent consumption of delivered food and infrequent screen time were also associated with better sleep quality. Conflicting results were found regarding the impact of dining at home versus dining out on the three sleep parameters. Conclusion: Increasing the intake of fruits, vegetables, and plant-based proteins are important factors that could help improve healthy sleep for those observing RF. In addition, regular PA and avoiding smoking may contribute to improving sleep during RF.
