Novel ball head screw and screwdriver design for implant-supported prostheses with angled channels: A finite element analysis

The primary objective of this study was to design the optimal geometry of a novel screwdriver, create the grooves on a ball head screw, and demonstrate its resistance to a torque of up to 40 Ncm at angulations of 0°, 15°, and 30° by using nonlinear finite element analysis. A secondary objective was to create a foolproof, easily recognizable system. The grooved ball head screw and geometry of the screwdriver, functioning from an angulation of 0° to 30°, was generated using Pro-ENGINEER Wildfire 5.0 software. Static structural analyses among bodies in contact were performed at different angles of 0°, 15°, and 30° at a torque of 20 Ncm and 40 Ncm using nonlinear finite element simulation by means of ANSYS 12.0. The maximum stress supported by the ball head screw and screwdriver was similar at 20 Ncm and 40 Ncm. Although greater deformations were found at 40 Ncm, these were small and might not affect the performance of the system. Further, the rupture torque value for the M2 connection was 55 Ncm for 0° and 30°, and 47.5 Ncm for 15°. Numerical simulation showed that the ball head system design can achieve the mechanical strength requirements expected for screws used in implant-supported restorations at an angulation of up to 30°. Finite element analysis showed this novel ball head screw and screwdriver system to be a good solution for angled screw channels in implant-supported prostheses.Postprint (published version

Application of a library of near isogenic lines to understand context dependent expression of QTL for grain yield and adaptive traits in bread wheat

(a) Summary of the mixed model analysis performed for the grain number components studied comprising 553 NILs carrying the Avalon or Cadenza alleles in the introgressed region in 2013. (b) Average values for the two groups (carrying the Avalon or Cadenza alleles in the QTL region) based on the chromosome and background in 2013. Significant difference between Avalon and Cadenza alleles are highlighted in bold (spikes/m2 (S), spikelet/spike (s/S) and grains/spikelet (G/S). (PDF 111 kb

Comparison of COVID-19 incidence and mortality between rural and urban areas in Catalonia

Facultat de Farmàcia i Ciències de l'Alimentació, Universitat de Barcelona.Treballs Pràctics de l' Assignatura de Salut Pública del Grau de Farmàcia. Treballs Curs: 2021-2022, Tutora: Maria Grau Magaña[eng] Background. COVID-19 has had a different impact on multiple aspects, depending on the county or region where it has been studied. Therefore, in this study we have established the differences in terms of the variables of incidence and mortality between the regions of “La Garrotxa” and “Barcelonès”. Methods. This analytical and observational study compares incidence and mortality between “La Garrotxa” and “Barcelonès” regions due to COVID-19 during the period March 1, 2020 - September 30, 2021. To this end, we have standardized the data by age and sex distribution using the direct method to calculate the cumulative incidence and the indirect method to determine the mortality ratio. Results. The cumulative incidence of COVID-19 is higher in the region of “La Garrotxa” (139 / 1,000 inhabitants in men and 142 / 1,000 inhabitants in women) than in that of “Barcelonès” (125 / 1,000 inhabitants and 109 / 1,000 inhabitants, respectively). On the other hand, mortality ratio due to COVID-19 is higher in “Barcelonès” (1,226 in men and 1,891 in women) than in “La Garrotxa” (0.990 in men and 1,498 in women). Conclusion. The incidence of COVID-19 is higher in “La Garrotxa” than in “Barcelonès” and the mortality due to COVID-19 is higher in “Barcelonès”. For this reason, prevention measures for the disease should be implemented taking into account the individual characteristics of each population, such as the distribution by age and sex.[cat] Antecedents. La COVID-19 ha tingut un impacte diferent en diversos aspectes, segons la comarca o regió en la que ha estat estudiada. Per consegüent, en aquest estudi hem establert quines són les diferències en quant a les variables d’incidència i mortalitat entre les comarques de la Garrotxa i el Barcelonès. Mètodes. Aquest estudi analític i observacional compara la incidència i la mortalitat entre la comarca de la Garrotxa i el Barcelonès degudes a la COVID-19 durant el període 1 març de 2020 - 30 setembre de 2021. Amb aquest objectiu, per una banda hem estandarditzat les dades per distribució d’edat i sexe utilitzant el mètode directe per calcular la incidència acumulada i el mètode indirecte, per determinar la raó de mortalitat. Resultats. La incidència acumulada de COVID-19 és major en la comarca de la Garrotxa (139/1.000 habitants en homes i 142/1.000 habitants en dones) que en la del Barcelonès (125/ 1.000 habitants i 109/1.000 habitants, respectivament). Per contra, la raó de mortalitat deguda a la COVID-19 és major al Barcelonès (1,226 en homes i 1,891 en dones) que a la Garrotxa (0,990 en homes i 1,498 en dones). Conclusions. La incidència de COVID-19 és major a la Garrotxa que al Barcelonès i la mortalitat deguda a la COVID-19 és major al Barcelonès. Per aquest motiu, les mesures de prevenció de la malaltia s’haurien d’implantar tenint en compte les característiques individuals de cada població, com serien la distribució per edat i sexe

Markers of Monocyte Activation, Inflammation, and Microbial Translocation Are Associated with Liver Fibrosis in Alcohol Use Disorder

Background: The association between markers of inflammation (interleukin (IL)-6 and IL-10), monocyte activation (sCD163 and sCD14), and microbial translocation (lipopolysaccharide (LPS) and LPS binding protein) and liver fibrosis in patients with alcohol use disorder (AUD) and no overt liver disease is not well established. Methods: We studied patients admitted for treatment of AUD at two hospitals in Barcelona. Advanced liver fibrosis (ALF) was defined as FIB-4 > 3.25. Results: A total of 353 participants (76.3% male) were included and 94 (26.5%) had ALF. In adjusted correlation analyses, sCD163, sCD14, IL-6, IL-10, and LPS binding protein levels directly correlated with FIB-4 values (adjusted correlation coefficients 0.214, 0.452, 0.317, 0.204, and 0.171, respectively). However, LPS levels were inversely associated with FIB-4 (-0.283). All plasma marker levels in the highest quartile, except LPS, were associated with ALF (sCD163, sCD14, IL-6, IL-10, and LPS binding protein: adjusted odds ratio (aOR) 11.49 (95% confidence interval 6.42-20.56), 1.87 (1.11-3.16), 2.99 (1.79-5.01), 1.84 (1.11-3.16), and 2.13 (1.30-3.50), respectively). Conversely, LPS levels in the lowest quartile were associated with ALF (aOR 2.58 (1.48-4.58), p < 0.01). Conclusion: In AUD patients, plasma levels of the markers of inflammation, monocyte activation, and microbial translocation are associated with ALF
