Acrylic resins-based artificial teeth are frequently used for the fabrication of dentures has and contribute a very strong share in the global market. However, the scientific literature reporting the comparative analysis data of various artificial teeth is scarce. Focusing on that, the present study investigated various types of commercially available artificial teeth, composed of polymethyl methacrylate (PMMA). Artificial teeth are characterized for chemical analysis, morphological features, thermal analysis, and mechanical properties (surface hardness, compressive strength). Different types of artificial teeth showed distinct mechanical (compression strength, Vickers hardness) and thermal properties (thermal gravimetric analysis) which may be attributed to the difference in the content of PMMA and type and quantity of different fillers in their composition. Thermogravimetric analysis (TGA) results exhibited that vinyl end groups of PMMA degraded above 200 °C, whereas 340-400 °C maximum degradation temperature was measured by differential thermal analysis (DTA) for all samples. Crisma brand showed the highest compressive strength and young modulus (88.6 MPa and 1654 MPa) while the lowest value of Vickers hardness was demonstrated by Pigeon and Vital brands. Scanning electron microscope (SEM) photographs showed that Crisma, Pigeon, and Vital exhibited characteristics of a brittle fracture; however, Artis and Well bite brands contained elongated voids on their surfaces. According to the mechanical analysis and SEM data, Well bite teeth showed a significantly higher mechanical strength compared to other groups. However, no considerable difference was observed in Vickers hardness of all groups. Graphical abstract.

Fulltext Association between sarcoidosis and cardiovascular Outcomes: A systematic review and Meta-analysis

BACKGROUND: Sarcoidosis is a chronic inflammatory disorder of unknown etiology associated with high morbidity and mortality. Its association with cardiovascular outcomes is under-documented.
AIM: The aim of this study was to assess the adverse cardiovascular outcomes in patients with sarcoidosis compared with that of non-sarcoidosis.
METHODOLOGY: Online databases including PubMed, Embase and Scopus were queried from inception until March 2022. The outcomes assessed included all-cause mortality (ACM) and incidence of ventricular tachycardia (VT), heart failure (HF) and atrial arrhythmias (AA).
RESULT: A total of 6 studies with 22,539,096 participants (42,763 Sarcoidosis, 22,496,354 Non-Sarcoidosis) were included in this analysis. The pooled prevalence of sarcoidosis was 13.1% (95% CI 1% to 70%). The overall mean age was 47 years. The most common comorbidities were hypertension (12.7% vs 12.5%), and diabetes mellitus (5.5% vs 4%) respectively. The pooled analysis of primary endpoints showed that all-cause mortality (RR, 2.08; 95% CI: 1.17 to 3.08; p = 0.01) was significantly increased in sarcoidosis patients. The pooled analysis of secondary endpoints showed that the incidence of VT (RR, 15.3; 95% CI: 5.39 to 43.42); p
Fulltext Inflammatory bowel disease and associated cardiovascular disease outcomes: A systematic review

BACKGROUND: There is limited and conflicting data available regarding the cardiovascular disease outcomes associated with inflammatory bowel disease (IBD).
OBJECTIVE: We aim to perform a systematic review to evaluate the cardiovascular outcomes and mortality associated with IBD patients.
METHODS: A systematic literature search has been performed on PubMed, Embase, Cochrane, and Scopus from inception till May 2022 without any language restrictions.
RESULTS: A total of 2,029,941 patients were included in the analysis from 16 studies. The mean age of the patients was 45.6 years. More females were found compared with males (57% vs 43%). The most common risk factors for cardiovascular disease (CVD) included smoking (24.19%) and alcohol (4.60%). The most common comorbidities includes hypertension (30%), diabetes mellitus (14.41%), dyslipidemia (18.42%), previous CVD (22%), and renal disease (10%). Among outcomes, all-cause mortality among IBD patients was 1.66%; ulcerative colitis (UC): 15.92%; and Crohn disease (CD): 0.30%. Myocardial Infarction (MI) among IBD patients were 1.47%, UC: 30.96%; and CD: 34.14%. CVD events among IBD patients were 1.95%. Heart failure events among IBD patients were 5.49%, stroke events among IBD patients were 0.95%, UC: 2.63%, and CD: 2.41%, respectively.
CONCLUSION: IBD patients are at higher risk for adverse cardiovascular outcomes, especially in women. Although there remains a lack of concrete treatment algorithms and assessment parameters that better characterize IBD risk factors, nutritional modifications and physical activity should be at the forefront of CVD prevention in IBD.
