Abstract

Abstract Background The purpose of this pilot in-vitro study was to assess the effect of sterilization on the intra-implant axis, inter-implant axis, intra-implant distance and inter-implant distance of three implants in a straight line by using laboratory scanner (LBS) versus intra-oral scanner (IOS) with intra-oral scan bodies (ISB). Methods: A printed 3D model with three internal hex analogs in the positions 15#,16#,17# was used. Zirkonzhan (ZZ) intra-oral scan body (ISB), two-piece titanium was used. The ZZ ISBs were scanned by 7 Series dental wings (LBS) and 30 times by Primescan (IOS) pre sterilization and 30 times post sterilization. For each scan (pre and post) stereolithography (STL) file was created and a comparison between all the scans pre sterilization and post sterilization were superimposed on the laboratory scan by using a 3D analyzing software. A Kolmogorov-Smirnov test performed followed by Wilcoxon Signed Ranks tests. (p

Abstract

Introduction Hydroxychloroquine (HCQ) emerged early in the course of the coronavirus disease 2019 (COVID-19) pandemic as a possible drug with potential therapeutic and prophylactic benefits. It was quickly adopted in China, Europe, and the USA. We systematically reviewed the existing clinical evidence of HCQ use for the prevention and treatment of COVID-19. Methods We screened for clinical studies describing HCQ administration to treat or prevent COVID-19 in PubMed. We included randomized controlled trials (RCTs), non-randomized comparative cohorts, and case series studies that had all undergone peer review. Results A total of 623 studies were screened; 17 studies evaluating HCQ treatment were included. A total of 13 were observational studies, and 4 were RCTs. In terms of effect on mortality rates, observational studies provided conflicting results. As a whole, RCTs, including one large British RCT that has not yet been published, showed no significant effect of HCQ on mortality rates, clinical cure, and virologic response. The use of HCQ as a post-exposure prophylactic agent was found to be ineffective in one RCT. Conclusion There is no evidence supporting HCQ for prophylaxis or treatment of COVID-19. Many observational trials were methodologically flawed. Scientific efforts have been disappointingly fragmented, and well-conducted trials have only recently been completed, more than 7 months and 600,000 deaths into the pandemic.

Abstract

Basic science studies suggest that opioids aggravate disease severity and outcomes in acute pancreatitis. We sought to determine the association of opioid use and opioid type with the clinical course and outcome of acute pancreatitis.In this retrospective single-center observational study, we included all adult patients admitted with acute pancreatitis between 2008 and 2021. Patients were classified into 3 groups based on analgesia type: morphine, noonmorphine opioid, and nonopioid.We included 2308 patients. Of the patients, 343 (14.9%) were treated with morphine, 733 (31.8%) were treated with nonmorphine opioids, and 1232 (53.4%) patients were in the nonopioid group. The incidence of 30-day mortality did not differ significantly between study groups: 3.9%, 2.9%, and 4.4% in the nonopioid, nonmorphine-opioid, and morphine groups, respectively ( P = 0.366).In multivariate analysis, the composite end point consisting of 30-day mortality, invasive ventilation, emergent abdominal surgery, and need for vasopressors was significantly more likely to occur in the morphine group than in the nonopioid group (adjusted odds ratio, 1.69; 95% confidence interval, 1.1-2.598; P = 0.01).Mortality among acute pancreatitis patients did not differ significantly between patients receiving morphine, nonmorphine opioids, and nonopioids. However, morphine treatment was associated with higher rates of some serious adverse events.

Abstract

BACKGROUND: Atrial Fibrillation (AF) is the most common sustained tachi-arrhythmia. Thrombus formation in the left atrial appendage (LAA) increases the risk of stroke and systemic embolism in patients with AF. OBJECTIVES: The aim of this study was to compare thrombin generation in the LAA to the LA among patients with AF. METHODS: A cross-sectional study of consecutive patients with AF undergoing pulmonary veins catheter ablation. Blood samples from the femoral vein (FV), right atrium (RA), left atrium (LA), and LAA were collected during the catheter ablation procedures. Thrombin generation was assessed by a Calibrated Automated Thrombogram. The LAA-calibrated automated thrombogram parameters were compared with the RA, LA, and FV. RESULTS: A total of 47 consecutive patients were enrolled in the study. The endogenous thrombin potential and peak height were significantly higher in the LAA compared with the LA, the mean differences and 95% CI between the LA and LAA were -378.9 (-680.5, -77.2) (nM∗min) and -66.7 (-119.6, -13.8) (nM) in the endogenous thrombin potential and peak height respectively. CONCLUSION: In patients with AF undergoing catheter ablation, the LAA demonstrated increased thrombin generation compared with the LA. This finding might contribute to the understanding of why the LAA is more predisposed to thrombus formation than the LA. CLINICAL TRIALS REGISTRATION: NCT03795883

ARABIC alphabet, CURSIVE type, LITERACY
Abstract

The article offers information on the project Unified Arabic (UA), started by Lebanese professor Nasri Khattar in 1932, consisting of a set of 30 letterforms, one for each letter of the Arabic alphabet. Topics discussed include UA's socio-political implications recognized by International Business Machines, simulate the cursive forms during the 15th century, economic effects of the impracticality of printed Arabic, and missionary Frank Laubach's mission for the abolishment of illiteracy.
