Postpartum tension fracture regarding bilateral leg: An instance statement.
The objective of this study is to present a tool to help understand how variables associated with oral cancer prevention relate to each other in a social network. A search of the Scopus database was performed using terms related to oral cancer and prevention from 2000 to 2020. The keywords were used as nodes and were analyzed using NodeXL, which produced the network graphic analysis. From the 1004 publications available, 4038 different keywords were obtained and then grouped into 75 constructs based on conceptual similarity. The most influential nodes were risk factors, comorbidities, epidemiology, and treatment. However, topics such as technology, telemedicine, self-examination, and diagnostic delay remain far removed from central relations. Network analysis enabled us to observe the bias of biological and basic science in the field and identify a need for studies concerning primary prevention, behavioral interventions, and inequalities in oral cancer.This study assessed the association between self-reported oral health and the normative indices of dental caries in an adolescent population. This study is based on a 6-year data from a cohort, beginning in 2012, with 1,134 twelve-year-old adolescents. After three phases of data collection, 68% of the samples were followed up. Self-reported oral health was evaluated through the question "Would you say that the health of your teeth, lips, jaws, and mouth is …?", and answers were categorized as "good" or "poor." Calibrated dentists examined clinical conditions using the decayed, missing, and filled teeth (DMFT) index. Statistical analysis was performed using multilevel logistic regression models, considering the dependence of those observed thrice and adjusted for demographic, socioeconomic, and dental visit variables. Adolescents who evaluated their oral health as poor had higher mean DMFT (OR 1.35; CI95% 1.22-1.50). When evaluated separately, decayed (OR 2.43; CI95% 1.83-3.23) and missing (OR 3.94; CI95% 1.26-12.26) teeth also presented significant results, showing poor self-reported oral health associated with a higher mean. Adolescents' self-perceived oral health was associated with normative dental caries indices, and this association was maintained throughout adolescence.This study aimed to screen the public procurement for dental adhesives in a public health system and evaluate the variables associated with the type and cost of purchased materials. A time series was conducted with secondary data collated from the Brazilian Databank of Healthcare Prices (BDHP). All public procurements for adhesive systems registered from 2010 to 2019 were collated. The frequency of purchase was described, and a multiple linear regression model was used to assess the influence of unit price on predictor variables. read more Multinomial logistic regression was conducted to describe the influence of selected variables on the probability of purchase for different classes of adhesive systems. A total of 2,752 purchases were analyzed, and the total cost of these materials reached US$ 7,022,659.00 in the 10 analyzed years. The 3-step Etch & Rinse adhesives corresponded to 45.63% of the processes, with increased probability of being purchased over time. The process conducted by public universities in recent years, using the auction modality, presented lower unit prices. The year of purchase, the type of institutions, the institution's location, and the procurement modality influenced the procurement process. The performed analyses contribute to the understanding of the variables associated with the procurements for adhesive systems, providing valuable information for rationalizing public expenditure and for implementing evidence-based practices to guarantee cost-effective and clinically effective procedures for users of the Brazilian public healthcare system.Aldehyde dehydrogenase 1 (ALDH-1) is a marker of stem cells in a variety of diseases, but its role in individuals with chronic inflammatory periapical lesions remains unknown. The aim of this study was to investigate the presence of cells with a stem cell profile based on the immunoexpression of ALDH-1 in periapical granulomas (PGs) and radicular cysts (RCs). A total of 51 cases of periapical lesions (25 PGs and 26 RCs) were subjected to immunohistochemical study. The anti-ALDH-1 antibody was applied using the immunoperoxidase technique. An immunoexpression score (intensity vs. percentage of cells) was used, with the cases being classified as low expression (score 0 to 4) and high expression (score 6 to 9). The Chi-square test was used with a 5% level of significance. Immunoexpression of ALDH-1 was detected in all cases of PGs and RCs. In PG cases, the expression was diffuse in connective tissue cells, with most cases exhibiting high expression (n = 18; 69.2%), while in RC cases the expression revealed focal distribution in cells of the capsule and epithelial cells of the cystic lining, with most cases classified as low expression (n = 18; 72%). Significant differences in the expression scores of ALDH-1 were observed in PGs (p = 0.003). The variable expression of ALDH-1 suggests the presence of cells with stem cell profiles in PGs and RCs. These findings suggest that periapical tissues infiltrated by chronic inflammation can recruit important cells for the repair or evolution of periapical lesions.This study evaluated the association between socioeconomic factors and stages of dental caries in children one to five years of age. A cross-sectional study was conducted involving 759 children enrolled in preschools in Diamantina, Brazil. The parents/caregivers filled out a form addressing socioeconomic factors. Add to the end of this sentence and categorized in caries free (code 0 and 1), no obvious decay (code 2 and 3) and obvious decay (code 4, 5 and 6). Statistical analysis was performed using the Mann-Whitney test and multinomial regression. The prevalence of "no obvious decay" was higher among children from families with a larger number of income-dependent individuals (OR 2.47; 95%CI 1.41-4.31). The higher prevalence of "obvious decay" was associated with the child's age (OR 1.36; 95%CI 1.16-1.58), attending a public preschool (OR 2.38; 95%CI 1.31-4.34), a larger number of income-dependent individuals (four to five individuals OR 1.71; 95%CI 1.09-2.74; more than five individuals OR 3.41; 95%CI 1.95-5.94), no access to a dentist (OR 2.14; 95%CI 1.48-3.09), and lower income (OR 1.72; 95%CI 1.19--2.49). It was concluded that the variable of a larger number of income-dependent individuals was associated with both no obvious decay and obvious decay. Child's age, type of preschool, access to a dentist, and income were associated with obvious decay.Appropriate research reports are important to facilitate the evaluation of studies and the decision-making by dentists and policymakers. This meta-research study assessed the conformity of randomized clinical trials (RCTs) on atraumatic restorative treatment (ART) restorations with the CONSORT recommendations and their risk of bias (RoB). Cochrane Library, MEDLINE, BBO, LILACS, Scopus, and Web of Science databases were searched from April 2019 to June 2021 for RCTs that assessed the longevity of ART restorations in children. A specific tool was used to assess adherence to the CONSORT recommendations; RoB was evaluated with the Cochrane risk-of-bias tool. Descriptive analyses included the number of studies by journal, follow-up period, country, and quality assessments. A total of 2,181 papers were retrieved and 36 of them were analyzed qualitatively. The overall CONSORT mean score (CONms) was 22.52 ± 6.17 out of 32 points. The best described items were intervention and outcomes, whereas allocation concealment was described in only 22% of the papers. Significant differences in CONms were detected in the analysis by country and publication dates. High CONms were observed in recently published papers (26.7 ± 3.1) when compared to first ART studies (18.1 ± 4.6; p less then 0.001). RoB was low in four studies, unclear in 11, and high in 21. Adherence of the papers to the CONSORT recommendations was not fully achieved and most of the papers had unclear and high RoB (PROSPERO registration #CRD42020201460).The aim of the present study was to analyze the relationship of OM with possible risk factors such as oral health condition, immunological status and IL-1β profile in patients submitted to hematopoietic stem cell transplantation (HSCT). Fifty-four individuals submitted to HSCT were included. All patients received previous dental treatment and photobiomodulation (PBM) as the institutional OM preventive protocol. OM scores, immune status, and IL-1β levels were determined during the conditioning period and at D+3 and D+8 after HSC infusion. IL-1β gene polymorphism was also analyzed during conditioning. Possible associations of OM with risk factors were analyzed using conditional Fisher's exact test. OM was observed in 34 patients (62.9%) classified as Grade 1 (13 patients/24.1%), Grade 2 (14 patients/25.9%), Grade 3 (3 patients/5.5%), and Grade 4 (4 patients/7.4%). Allogeneic HSCT individuals exhibited a higher OM grade than autologous subjects. Moreover, an association was observed between severe OM and severe gingivitis (p = 0.01), neutropenia (p = 0.03), and leukopenia (p = 0.04). A significant association between OM and lower IL-1β levels was detected at three time points, i.e., conditioning (p = 0.048), D+3 (p = 0.01), and D+8 (p = 0.005). The results showed that IL-1β gene polymorphism was not associated with OM. Our study provided important insights into the scope of OM risk factors in the setting of HSCT. Patients submitted to HSCT with severe gingivitis prior to chemotherapy and with severe neutropenia and leukopenia exhibited a higher OM grade. Further investigation will be necessary to better understand the exact role of IL-1β in the context of OM pathobiology and to validate cytokine analysis in larger cohorts.Oral tolerance blocks the development of specific immune responses to proteins ingested by the oral route. One of the first registries of oral tolerance showed that guinea pigs fed corn became refractory to hypersensitivity to corn proteins. Mice fed with chow containing corn are tolerant to zein, and parenteral injection of zein plus adjuvant blocks immunization to unrelated proteins injected concomitantly and reduces unspecific inflammation. Extensive and prolonged inflammatory infiltrate in the wound bed is one of the causes of pathological wound healing. Previous research shows that intraperitoneal injection of zein concomitant with skin injuries reduces the inflammatory infiltrate in the wound bed and improves wound healing. Herein, we tested if one subcutaneous injection of zein before skin injury improves wound healing. We also investigated how long the effects triggered by zein could improve skin wound healing. Mice fed zein received two excisional wounds on the interscapular skin under anesthesia. Zein plus Al(OH)3 was injected at the tail base at 10 min, or 3, 5, or 7 days before skin injuries. Wound healing was analyzed at days 7 and 40 after injury. Our results showed that a zein injection up to 5 days before skin injury reduced the inflammatory infiltrate, increased the number of T-cells in the wound bed, and improved the pattern of collagen deposition in the neodermis. These findings could promote the development of new strategies for the treatment and prevention of pathological healing using proteins normally found in the common diet.
