title: IMPACT OF MEASURES TO FIGHT THE PANDEMIC COVID-19 ON KNEE ARTHROPLASTIES IN BRAZIL

description: ABSTRACT Objective: To assess the impacts of measures to face COVID-19 on total knee arthroplasty procedures in the country, based on data provided by the SUS Information and Informatics Department (DATASUS). Methods: Cross-sectional study of secondary data in the public domain, available on the website of the Department of Information and Informatics of SUS (DATASUS), containing information about hospital admissions in the SUS. Results: Brazil suffered a 51.82% decrease, on average, in the performance of total knee arthroplasty by the Unified Health System (SUS) in 2020, due to measures to face COVID-19. The analysis by region offers more details on this reduction in the number of procedures. In the Northeast, the decrease was on average 48.02%, whereas in the Center-West it was 65.61%. Southeast, North, and South registered an average decrease of 49.38%, 51.81%, and 55.06%, respectively. Conclusion: COVID-19 impacted the realization of TKA in Brazil, with greater and lesser levels of decline observed in different Brazilian regions. In the Southeast region, for example, the states of São Paulo and Minas Gerais were the most affected, mainly due to the large population concentration, as well as Paraná, which has high numbers of procedures and a sharp decrease in 2020. Level of Evidence III, Retrospective Comparative Study.

title: AN EFFICIENT INVENTORY MODEL-BASED GA FOR FOOD DETERIORATION PRODUCTS IN THE TOURISM INDUSTRY

description: ABSTRACT Background: The inventory control practice of deteriorating food products that are subject to an expiration date is a challenging process. Inappropriate inventory control practice leads to substantial waste of products and significant holding and purchasing costs. Purpose: This paper aims to develop an inventory control model-based Genetic Algorithm (GA) to minimize the Total Annual Inventory Cost (TAIC) function developed explicitly for the proposed model. Methodology: GA is used and tailored to provide the best reorder level of deteriorating food products. A case study of one of the five-star hotels in Iraq is conducted, followed by a sensitivity analysis study to validate the proposed model for varying reorder levels. Results and Conclusion: A minimum inventory cost is obtained with an optimum reorder level achieved by running GA. It is concluded that the optimal reorder level provided by the proposed GA minimized the monthly inventory cost of products.

title: Engineers of the Grande Mar Redondo: engineering and nature in the bays of Paranaguá and Antonina (1871-1879)

description: ABSTRACT The construction of a railroad between the coast and the capital of Paraná generated conflicts among Brazilian engineers, as the local political elites claimed the port station and the railroad layout. Engineers are considered to be experts who, according to Bruno Latour (2004), handled technical processes transitioning between science and politics. The article analyzes the performance of these engineers in the spatial configuration of the coast of Paraná, seeking to understand the engineering projects in the set of relations between society and nature. The research was developed from the analysis of the technical reports of the engineers and it is concluded that, based on a positivist science, the engineers legitimized the desires of the political groups that idealized the modernization and progress of the province.

title: The insertion of Baptist Christianity in Mozambique: Reasons that led missionaries to choosing only Portuguese settlers as their object of evangelization (1950-1971)

description: ABSTRACT This article analyzes the insertion of Baptist Christianity in Mozambique, a former Portuguese colony in Africa, between the years of 1950 and 1971. In that context, the Christian missionaries get involved only settlers who lived there. The question that we will try to answer is: why such evangelicals did not include native Mozambicans in their projects? We will consider the historical reasons that explain the socio-racial primacy mentioned, questioning some concepts used in studies about the history of Protestantism, especially those of “mission” and “migration” Protestantism, here questioned from notes of the Italian School of History of Religions, which supports for the main conclusion of the text, namely: instead of an alleged non-missionary nature, this project was, rather, proselytizing. The group’s confessional print media will be our main documentary source. We hope to contribute to the debates on Christian missions in Africa during the 20th century, especially in the scope of the Cultural History of Religions.

title: Development of a sodium fluoride and stannous chloride-containing gel for treatment of dental erosion

description: Abstract: This study synthesized and tested experimental gels containing fluoride (F-) and stannous (Sn2+) ions for the control of dental erosion. Enamel and dentin polished specimens were eroded (1% citric acid solution, 10 min) and randomly allocated into 5 groups (n=10): Placebo - Hydroxypropyl Methylcellulose (HMC) gel; F+Sn+HMC - 7,500 ppm F- / 15,000 ppm Sn2+; F+HMC - 7,500 ppm F-; Commercial acidulated phosphate fluoride gel (12,300 ppm F-); and Control - no treatment. After treatment (applied for 60 s), specimens underwent an erosion-remineralization cycling (5 min in 0.3% citric acid solution, 60 min in artificial saliva, 4×/day, 20 days). Surface loss (SL, in µm) was determined after the 5th, 10th and 20th days of cycling (α=0.05). For enamel, after 5 and 10 days, F+Sn+HMC presented the lowest SL, which did not differ from the commercial gel. After 20 days, no differences were found between commercial, F+HMC, and F+Sn+HMC groups. Placebo did not differ from the control at any time points, and both groups presented the highest SL when compared to the other groups. For dentin, on the 5th day, F+Sn+HMC, F+HMC and commercial did not differ significantly, showing lower SL than the control and the placebo. On the 10th day, F+Sn+HMC and commercial presented the lowest SL compared to control and placebo. After 20 days, only the commercial gel showed lower SL than the control and placebo. Thus, the experimental F+Sn+HMC gel was able to control the progression of tooth erosion.

title: Association between hypomineralization of deciduous and molar incisor hypomineralization and dental caries

description: Abstract This study aimed to evaluate the association between the severity of hypomineralized second primary molars (HSPM), molar-incisor hypomineralization (MIH) and dental caries in children. 450 children between the ages of 6 and 7 years were included in this cross-sectional study. A calibrated examiner classified the enamel hypomineralizations and dental caries lesions using the MIH and HSPM and the Nyvad criteria, respectively. The primary outcome was the severity of MIH according to the severity of HSPM. Statistical analysis was performed using the generalized linear model and ordinal logistic regression. The prevalence of concomitant MIH and HSPM was 26% sex and age adjusted. Mild enamel defects were more frequent than severe enamel defects. An association was found between the severity of MIH and HSPM, both for mild defects (OR=87.54; 95%CI: 55.87, 137.17) and severe defects (OR=82.15; 95%CI: 45.72, 147.61). The severity of hypomineralization in permanent molars was associated with the activity of dental caries lesions (OR=29.85; 95%CI: 12.95, 68.83). To conclude, there is a strong association between the severity of HSPM and MIH, which is more significant in the presence of active dental caries lesions.

title: A computational modeling method for root canal endoscopy using a specific CBCT filter: A new era in the metaverse of endodontics begins

description: Abstract A contemporary technological revolution has started a new era in the metaverse of Endodontics, a world of virtual operational possibilities that use an exact replica of the natural structures of the maxillofacial complex. This study describes a modeling method for root canal endoscopy using modern cone-beam CT (CBCT) software in a series of clinical cases. The method consists in acquiring thin CBCT slices (0.10mm) in the coronal, sagittal, and axial planes. A specific 3D volume filter, the pulp cavity filter of the e-Vol DX CBCT software, was used to navigate anatomical root canal microstructures, and to scan them using root canal endoscopy. The pulp cavity filter should be set to synchronize CBCT scans from 2D mode - multiplanar reformations (MPR) - to 3D mode - volumetric reconstruction. This filter, when adopting the option of volumetric reconstruction, the developed algorithm leaves the dentin density in transparent mode so that the pulp cavity may be visualized. The algorithm applied performs the suppression (visual) of areas with dentin density. This ensures 3D visualization of the slices and the microanatomy of the root canal, as well as a dynamic navigation throughout the pulp cavity. This computational modeling method adds new resources to Endodontics, which may impact the predictability of root canal treatments positively. The virtual visualization of the internal anatomy of an exact replica of the canal ensures better communications, reliability, and clinical operationalization. Root canal endoscopy using this novel CBCT filter may be used for clinical applications together with innovative digital and virtual-reality resources that will be naturally incorporated into the principles of Endodontics.

title: Labour and free labourers: the Indians in the Rio de Janeiro Navy Arsenal, 19th century

description: ABSTRACT The present text proposes to recover the process of incorporating the Indians into the universe of urban labourers in Rio de Janeiro in the 19th century, analyzing their presence in the Navy Arsenal. The proposal is to reintroduce the Indians on the world of labour and seeking to open new fields of debate with a historiography of African slavery. By addressing the presence of native populations in the world of Rio’s labour, it is expected to contribute to an expansion of the complexity of the concept of “free labourers” in the 19th century.

title: STUDY BETWEEN SEMI-CONSTRAINED TOTAL KNEE ARTHROPLASTY WITH OR WITHOUT INTRAMEDULLARY STEM

description: ABSTRACT Objective: This research sought to carry out a comparative study observing the clinical and radiographic analysis of primary prostheses of the type TC3 Depuy Johnson® with or without a stem during a short-term follow-up. Methods: The sample was divided into three groups: Group 1 (with stem), Group 2 (without stem) and Group 3 (mixed). Patients were evaluated to assess whether the implants were loosening and a clinical analysis was performed. Results: Preoperative deformities were predominantly considered severe. The total range of motion in the postoperative period was above 96.7° in the three groups. In the postoperative period, the femoral-tibial angle oscillated on average between 5 to 6° valgus. There was no record of implant loosening for cases treated with stem, and the incidence of loosening was 14.3% for the group without stem and 16.7% among cases in the mixed group. Conclusion: In general, preoperative deformities were considered severe. In the postoperative period, the total range of motion was above 96.7°. The postoperative femoral-tibial angle obtained an average of 5 to 6° valgus. There is no significant difference in implants loosening in the three groups.

title: RESULTS OF THE SURGICAL TREATMENT OF ARTICULAR SCAPULAR FRACTURES

description: ABSTRACT Introduction: Scapular fractures are rare injuries and are often associated with high-energy trauma, with joint fractures accounting for only 15% of all scapular fractures. Surgical treatment is indicated for fractures with large deviations and with joint instability. Objective: This study evaluates the clinical and functional results after surgical treatment of scapular fractures. Methods: Eight patients with scapular fractures were surgically treated between 2013 and 2019. For indication for surgical treatment, mediolateral deviations, glenopolar angle, angular deviations and joint deviations greater than 4 mm were taken into account. Radiographic results of consolidation, range of motion, functional score and visual analogue pain scale were obtained. Results: In the mean follow-up of twenty-nine months (13-40 months), all patients presented fracture consolidation. The mean UCLA score was 29 points (with 75% good results and 25% moderate results). Regarding the range of motion, the mean elevation was 146° (ranging from 110° to 60°), lateral rotation of 62° (36-80°) and medial rotation at the level of T7 (T6-T10). The final VAS mean was 2.3. All patients returned to the pre-injury level at work. Conclusion: In this series of cases, surgical treatment of scapular articular fractures provided satisfactory results with low rates of complications, showing to be an option in selected cases of deviated fractures. Level of Evidence IV, Case Series.
