Efficacy of levamisole with standard care treatment vs. standard care in clinical presentations of non-hospitalized patients with COVID-19: a randomized clinical trial
Objective: The aim of this study was to evaluate the influence of adding a 10-day course of levamisole (LVM) to the standard care compared with standard care alone, on the clinical status of COVID-19 patients with mild to moderate disease. Methods: In this randomized open-label trial, we enrolled non-hospitalized patients with mild to moderate COVID-19 at nine health centers in Tehran province, Iran, in 2021. Patients were randomly assigned to receive a 10-day course of LVM with standard care (n=185) or standard care alone (n=180) in a 1:1 ratio. On days 1 to 10, LVM was administered orally at a dosage of 50 mg. The participants were called and followed on days 1, 3, 5, 7, 9, and 14. The measured parameters were general health condition, hospitalization rate, signs and symptoms, and adverse events. The generalized estimating equations model was used for analysis. Results: Among 507 randomized patients, 473 patients started the experiment and received LVM plus standard care or received the standard care alone; 385 patients included in the analysis; 346 (98%) patients completed the trial. The median age of the patients was 40 years [IQR: 32-50.75]; and 201 (55.1%) patiens were male. The mean age, sex ratio, and frequency of the underlying diseases of the patients in the two study groups had no statistically significant differences (P>0.05). Compared to the control group, LVM improved the general health condition of the patients (B=-0.635; 95% CI: -0.041,-0.329; P<0.001). Patients receiving LVM compared with standard care group had significantly lower odds of developing fever (OR=0.260; 95% CI: 0.113,0.599; P=0.002), chills (OR=0.223; 95% CI: 0.076,0.648; P= 0.006), fatigue (OR=0.576; 95% CI: 0.346,0.960; P=0.034), and myalgia (OR=0.544; 95% CI: 0.317,0.932; P=0.027). No significant difference was observed in the rate of hospitalization. Although the intervention group had greater adverse effects than the control group, the difference was not statistically significant. Conclusion: Findings of this study suggest that LVM has clinical benefits in improving patients’ health condition with mild to moderate COVID-19

Risk of permanent medical impairment after road traffic crashes: A systematic review
Purpose: To systematically review the risk of permanent disability related to road traffic injuries (RTIs) and to determine the implications for future research regarding permanent impairment following road traffic crashes. Methods: We conducted this systematic review according to the preferred reporting items for systematic reviews and meta-analysis statement. An extended search of the literature was carried out in 4 major electronic databases for scientific research papers published from January 1980 to February 2020. Two teams include 2 reviewers each, screened independently the titles/abstracts, and after that, reviewed the full text of the included studies. The quality of the studies was assessed using the strengthening the reporting of observational studies in epidemiology (STROBE) checklist. A third reviewer was assessed any discrepancy and all data of included studies were extracted. Finally, the data were systematically analyzed, and the related data were interpreted. Results: Five out of 16 studies were evaluated as high-quality according to the STROBE checklist. Fifteen studies ranked the initial injuries according to the abbreviated injury scale 2005. Five studies reported the total risk of permanent medical impairment following RTIs which varied from 2% to 23% for car occupants and 2.8% to 46% for cyclists. Seven studies reported the risk of permanent medical impairment of the different body regions. Eleven studies stated the most common body region to develop permanent impairment, of which 6 studies demonstrated that injuries of the cervical spine and neck were at the highest risk of becoming permanent injured. Conclusion: The finding of this review revealed the necessity of providing a globally validated method to evaluate permanent medical impairment following RTIs across the world. This would facilitate decision-making about traffic injuries and efficient management to reduce the financial and psychological burdens for individuals and communities
Therapeutic Effects of Hydroalcoholic Extracts from the Ancient Apple Mela Rosa dei Monti Sibillini in Transient Global Ischemia in Rats
The Mela Rosa dei Monti Sibillini is an ancient apple variety cultivated by Romans in the foothills of the Sibillini Mountains, central Italy, showing potential as a source of nutraceuticals. The purpose of this study was to evaluate the protective effects of the hydroalcoholic extracts from the peel (APE) and pulp (APP) of this fruit in an animal model of transient global ischemia. Chemical constituents were analyzed by liquid chromatography–mass spectrometry (LC-DAD-MSn) indicating several polyphenols such as B-type procyanidins, quercetin derivatives and hydroxycinnamic acids as the main bioactive components. Acute pre-treatment of extracts (30 mg/kg, i.p.) significantly decreased the brain levels of the pro-inflammatory cytokines IL-1β (p < 0.01) and TNF-α (p < 0.001 and p < 0.01 for APE and APP, respectively), the expression of caspase-3 (p < 0.01, For APE) and MDA (p < 0.05), a lipid peroxidation biomarker in rats. Both extracts restricted the pathological changes of the brain induced by ischemic stroke in hematoxylin and eosin assay. Moreover, they improved the scores of behavioral tests in grid-walking and modified neurological severity scores (mNSS) tests. In conclusion, these results proved this ancient Italian apple is a source of nutraceuticals able to protect/prevent damage from brain ischemia
