    Abstract Background: The overwhelming outbreak of covid-19 has forced governments all over the world to consider different measures to face this challenging situation. A vitally important element to the declining transmission of viruses is changing behaviors based on reliable information. This study was designed and implemented to identify factors affecting the preventive behaviors during the covid-19 pandemic.
    Methods: This thematic synthesis was carried out in order to create a set of central themes that summarize all of the issues raised in the articles reviewed in this study. We used PRISMA 2020 guidelines to direct this systematic review and meta synthesis. The process of analyzing data includes three different stages: 1) creating codes; 2) production of descriptive themes; 3) and finally, the creation of analytical themes. The Standards for Reporting Qualitative Research checklist was used to evaluate the articles' quality.
    Results: Five central themes emerged from 8 included articles, (1) Social factors (subthemes: environmental context, political leadership, multimedia), (2) Cultural factors (subthemes: national culture, religious culture, the family beliefs, work culture, foreign culture), (3) Economic factors (subthemes: economic situation of the individual, the government supports, infrastructures), (4) Personal factors (subthemes: people experiences, cognitive ability, physical factors, different motivational level, sense of responsibility, risk management, and self-management skills), and (5) Knowledge and Education factors (subthemes: access to information, skill training). Furthermore, SRQR items that were weakly reported were "researcher characteristics and reflexivity", "Sampling strategy", "Data collection methods", "Data analysis", and "techniques to enhance trustworthiness.
    Conclusion: Health policymakers and other public health officials in various countries can use the factors listed to develop appropriate, evidence-based policies. They should investigate behavioral characteristics in their community based on their abilities, and then design and implement appropriate executive actions.

    Abstract Spinal anaesthesia (SA) is one of the most prevalent types of anaesthetic procedures. There are very few reports of cord herniation through the site of spinal canal stenosis due to tumour. A 33-year-old female presented with acute paraparesis after spinal anaesthesia for caesarean section. Magnetic resonance imaging (MRI) revealed an intradural mass from posterior of T6 to T8-T9 interface. We operated the patient and after laminectomy of T6 to T9, dermoid tumour containing hairs was totally resected and cord was completely decompressed. After 6 months, the patient is without any neurological deficit. Puncturing the dura with cerebrospinal fluid (CSF) in the presence of an extramedullary mass could cause cord herniation through the blockade. In these cases, awareness about related signs even in absence of symptoms or complaints could help us to prevent post-SA neurological deficit.

    Abstract Abstract Solar collectors utilize solar energy, a sustainable and renewable source, to cater to both household and industrial needs. This paper investigated the usage of mono and binary nanoparticles in parabolic trough collectors. This paper used multiwalled carbon nanotube/Fe3O4 nanoparticles as the additives to the collector heat transfer fluid (in Syltherm 800 oil) and also evaluated the performance implications of energy systems in six scenarios. A MATLAB‐based computational model is provided to investigate the influence of employing binary nanoparticles on a solar collector's performance. The influence of nanoparticle modifications and volume percentages on energy, exergy, economic, and environmental aspects is studied. Finally, the impact of nanoparticles on each of the four mentioned areas is examined. At the same total energy rate, in the best case, adding 4% by volume of Fe3O4 (Case 2) to the base fluid increases the valuable energy rate absorbed from 7.32 kW in the base state to 7.50 kW (2.5%). The carbon dioxide produced in the system life cycle by using useful energy is called EnergoEnvironmental, and the carbon dioxide produced in the system life cycle by using useful exergy is called ExergoEnvironmental. At last, the calculation of the parameters EnergoEnviroEconomic and ExergoEnviroEconomic are done, the penalty policy is considered, and the calculations are generalized to solar collector power plants due to the carbon dioxide cost policies.

    Abstract BACKGROUND: The purpose of this study was determination of the prevalence of post-traumatic hydrocephalus (PTH) in patients who had traumatic brain injury (TBI) worldwide. METHODS: Four electronic databases including Scopus, PubMed, Embase, and Web of Science were searched in this meta-analysis. The random-effects model was applied for the pooled effect size of I2 > 50%. Subgroup analysis was done to evaluate the heterogeneity, and the Egger’s test was used to test the asymmetry of the funnel plots in order to assess the publication bias. RESULTS: A total of 48 studies with 11624 patients were evaluated. The pooled prevalence of PTH was 13% [95% confidence interval (CI): 11.0-15.0] and according to decompressive craniectomy (DC) surgery was 22.0% (95% CI: 18.0-26.0). This result among patients with severe TBI (sTBI) was 16.0% (95% CI: 13.0-19.0) and it was higher in the developed countries. The prevalence of PTH was generally higher in studies with a sample size lower than 100 (21.0%) and was generally lower in studies conducted between 1990 to1999 (4.0%). These results were not too different according to the study design. CONCLUSION: It is recommended to design a prospective clinical study in order to explain the true dynamics and circulation of the cerebrospinal fluid (CSF) after DC. Moreover, there is a need to evaluate the cost-effectiveness of DC in reducing the intracranial pressure in comparison with other available options. In fact, performing the clinical studies with higher quality in less developed countries could provide more reliable related results to achieve a true global conclusion.

    Abstract Medicinal plants are used by many people with Type 2 diabetes in Iran. The aim of this study was to explore why this is so, from their perspective. Sixteen persons with Type 2 diabetes in Yazd City, Iran, were interviewed in April and May 2020 for this study. A thematic analysis of the transcripts of those interviews was done using MAXQDA 10 software. Six themes were identified: beliefs about medicinal plants, psychological factors, accessibility and economic barriers, patients' knowledge and awareness, social pressure, and the role of family culture. The recommendation of the study is that health counselors and specialists should provide needed information and skills for the proper use of medicinal plants, and the pharmaceutical infrastructures need to be expanded to provide enough drugs to facilitate better access to needed medication and reduce reliance on medicinal plants for persons with Type 2 diabetes.

    Abstract This review provides an analysis of the theoretical methods to study the effects of surface modification on structural properties of nanostructured indium tin oxide (ITO), mainly by organic compounds. The computational data are compared with experimental data such as X-ray diffraction (XRD), atomic force microscopy (AFM) and energy-dispersive X-ray spectroscopy (EDS) data with the focus on optoelectronic and electrocatalytic properties of the surface to investigate potential relations of these properties and applications of ITO in fields such as biosensing and electronic device fabrication. Our analysis shows that the change in optoelectronic properties of the surface is mainly due to functionalizing the surface with organic molecules and that the electrocatalytic properties vary as a function of size.

    Abstract Background: Cervical spondyloptosis is usually caused by trauma, and correlated with significant neurological deficits that can include quadriplegia, respiratory disorders, vertebral artery injury, and death.
    Case description: A 34-year-old male presented with C2-C3 spondylolisthesis after a fall from a tree. Although he had no neurological deficits, CT and X-ray studies confirmed C2-C3 a spondyloptosis. He was treated with emergent anterior and posterior cervical reduction, decompression, and fixation, remaining neurologically intact in the postoperative period.
    Conclusion: Patients with C2-C3 spondyloptosis documented on X-ray/CT studies should be considered for circumferential decompression/fusion to preserve neurological function.
