ABSTRACT Rocky Mountain Spotted Fever is a rickettsial disease caused by the bacteria Rickettsia rickettsii. In Brazil, the disease is known as Brazilian spotted fever (BSF), being the most significant tick-borne disease in the country. Among the affected patients, only 5% of cases occur in children aged one to nine years. Typical symptoms of the disease are fever, rash, headache and digestive symptoms. Neurological manifestations such as seizures, aphasia and hemiparesis have been described in few patients. This study aimed to describe the case of an infant diagnosed with BSF who presented severe signs of neurological manifestation. rickettsii Brazil BSF, , (BSF) tickborne tick borne country patients 5 years rash seizures manifestation (BSF

Abstract Borosilicate glass was developed to enhance the mechanical behavior and smoothness of dental zirconia as an alternative to conventional glaze. This study assessed the mechanical and optical properties of 3 mol% yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) coated with borosilicate glass or a commercial glaze fired for an extended period of time. Disc-shaped 3Y-TZP zirconia specimens (Zpex, Tosoh) were sintered at 1550°C for 2 hours. The specimens were divided into three groups: as-sintered (control, C); commercial glaze (G); and borosilicate glass (SL). The glaze and borosilicate glass were applied over the zirconia and fired for 20 minutes at 950°C and 1200°C, respectively. Biaxial flexural strength, fractography, X-ray diffraction (XRD), roughness (Ra and Rz), fracture toughness (Vickers indentation method), color difference (∆E00), and translucency (TP00) analyses were conducted. The t-test or the one-way ANOVA and Tukey’s tests were used to analyze the data (α = 0.05). Flexural strength data were subjected to the Weibull analysis. The SL group exhibited the highest flexural strength (1025.8 MPa), whereas the C (859.41 MPa) and G (816.0 MPa) groups exhibited similar values. The SL group also had the highest characteristic strength. The fracture origin in all groups was on the zirconia surface. XRD analysis revealed that the specimens from the SL group contained tetragonal, cubic, and monoclinic phases. The SL group presented the lowest surface roughness. Fracture toughness in the SL group was lower than in the C group, but similar to that observed in the G group. The translucency and color differences observed in the G and SL groups were similar. Borosilicate glass enhanced the flexural strength of 3Y-TZP, promoted the smoothest surface, and exhibited optical properties similar to those of the glaze. mol yttriastabilized yttria stabilized 3YTZP YTZP 3Y TZP Y (3Y-TZP time Discshaped Disc shaped Zpex, Zpex (Zpex Tosoh 1550C 1550 hours assintered control, control (control C) (G) SL. .

Abstract Background Patients with immune-mediated rheumatic diseases (IMRDs) have been prioritized for COVID-19 vaccination to mitigate the infection severity risks. Patients with rheumatoid arthritis (RA) are at a high risk of severe COVID-19 outcomes, especially those under immunosuppression or with associated comorbidities. However, few studies have assessed the safety of the COVID-19 vaccine in patients with RA. Objective To evaluate the safety of vaccines against SARS-CoV-2 in patients with RA. Methods This data are from the study “Safety and Efficacy on COVID-19 Vaccine in Rheumatic Diseases,” a Brazilian multicentric prospective phase IV study to evaluate COVID-19 vaccine in IMRDs in Brazil. Adverse events (AEs) in patients with RA of all centers were assessed after two doses of ChAdOx1 (Oxford/AstraZeneca) or CoronaVac (Sinovac/Butantan). Stratification of postvaccination AEs was performed using a diary, filled out daily and returned at the end of 28 days for each dose. Results A total of 188 patients with RA were include, 90% female. CoronaVac was used in 109 patients and ChAdOx1 in 79. Only mild AEs were observed, mainly after the first dose. The most common AEs after the first dose were pain at the injection (46,7%), headache (39,4%), arthralgia (39,4%), myalgia (30,5%) and fatigue (26,6%), and ChAdOx1 had a higher frequency of pain at the injection (66% vs 32 %, p < 0.001) arthralgia (62% vs 22%, p < 0.001) and myalgia (45% vs 20%, p < 0.001) compared to CoronaVac. The more common AEs after the second dose were pain at the injection (37%), arthralgia (31%), myalgia (23%), headache (21%) and fatigue (18%). Arthralgia (41,4% vs 25%, p = 0.02) and pain at injection (51,4% vs 27%, p = 0.001) were more common with ChAdOx1. No serious AEs were related. With Regard to RA activity level, no significant difference was observed between the three time periods for both COVID-19 vaccines. Conclusion In the comparison between the two immunizers in patients with RA, local reactions and musculoskeletal symptoms were more frequent with ChAdOx1 than with CoronaVac, especially after the first dose. In summary, the AE occurred mainly after the first dose, and were mild, like previous data from others immunizing agents in patients with rheumatoid arthritis.

ABSTRACT Ensilage of refused fruit with forage is a viable approach to increase resource use in ruminant feed. The use of refused melon (Cucumis melo L. subsp. melo var. inodorus H. Jacq.) fruit (RMF), ensiled at 0%, 2%, 4%, 6%, or 8% of natural matter with sorghum (Sorghum bicolor (L.) Moench), was assessed in terms of chemical- bromatological composition and fermentative profile. Experimental silos filled with mixtures and hermetically sealed were used. After 34 d of fermentation, the silos were opened, and samples were analyzed. Dry matter concentration shows a quadratic increase (P < 0.05) with RMF inclusion in sorghum silage rising from 30.83% to 32.08% at 4% of RMF inclusion, followed by a reduction in the subsequent levels. There was a linear increase (P < 0.05) in ether extract, total digestible nutrients, digestible energy, metabolizable energy, and in vitro digestibility of DM and organic matter, increasing respectively 3.96%, 5.32%, 0.25 Mcal kg-1, 0.19 Mcal kg-1, 1.89% and 0.74% from 0% to 8% of RMF inclusion. There was a linear reduction (P < 0.05) of neutral detergent fiber, cellulose, hemicellulose, and lignin with RMF inclusion. We also observed a linear increase (P < 0.05) in ammoniacal N, acetic acid, propionic acid, butyric acid, and lactic acid concentrations in silage with the addition of RMF. The inclusion of RMF improved the chemical-bromatological composition and fermentative profile of sorghum silage, and an inclusion level of 8% is recommended.

Abstract Objective: To describe the health-related quality of life (QOL) in children with cerebral palsy (CP) associated with congenital Zika infection. Methods: Cross-sectional study of a consecutive series of children, followed in a referral multicentric rehabilitation network in Brazil. We invited the caregivers to respond to the Brazilian version of the Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM) questionnaire. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) 26.0™. We used absolute and relative frequencies for categorical variables and mean and standard deviation for continuous variables. Results: The sample consisted of 193 children, at mean age of 50.3±7.6 months. We observed a predominance of children with cerebral palsy (CP) with Gross Motor Function Classification System (GMFCS) level V (93.7%). Epilepsy (88.4%) was the most common comorbidity. CPCHILDTM mean scores were activities of daily living (ADL)/personal care 43.2±12.6; positioning, transferring and mobility 33.7±16.5; comfort and emotions 84.4±15.2; communication and social interaction (CoSI) 48.2±24.3; health 70.9±17.1; and overall quality of life (OQOL) 72.1±17.1. Total score was 54.8±11.3. Conclusions: Among children with cerebral palsy (CP) related to congenital Zika syndrome, the quality of life (QOL) scores were very similar to other populations with cerebral palsy (CP). The activities of positioning, transferring and mobility had the greatest impact on health-related quality of life (QOL). Rehabilitation strategies and public policies should prioritize aspects related to mobility for this population.

SUMMARY OBJECTIVE: This study aimed to evaluate the quality of life of patients with endometriosis before and after surgical treatment. METHODS: An observational, longitudinal, and prospective study was conducted with 102 women with pelvic pain and endometriosis that was unimproved by clinical treatment and indicated for surgical treatment. The patients’ quality of life was assessed using the 30-item Endometriosis Health Profile (EHP-30) questionnaire before and 3 and 6 months after surgery. The statistical tests were analyzed using the Statistical Package for Social Sciences version 17.0, and the Friedman test was used. RESULTS: There was a reduction in EHP-30 scores 3 and 6 months after surgery compared to before surgery, as well as 6 months after surgery compared to 3 months after surgery, in the central questionnaire (PART 1) and in Sections A, B, C, E, and F (p<0.0001). For Section D, there was a reduction in scores 6 months after surgery compared to before surgery (p<0.0001). CONCLUSION: Surgical treatment of endometriosis improves quality of life in several areas assessed by the EHP-30 questionnaire.

ABSTRACT The SISBIOTA-BRASIL was a three-year multimillion-dollar research program of the Brazilian government to document plants and animals in endangered/understudied areas and biomes in Brazil. Distributional patterns and the historical events that generated them are extensively unknown regarding Brazilian fauna and flora. This deficiency hinders the development of conservation policies and the understanding of evolutionary processes. Conservation decisions depend on precise knowledge of the taxonomy and geographic distribution of species. Given such a premise, we proposed to research the diversity of Diptera of the Brazilian western arc of Amazon, Cerrado, and Pantanal in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia. Three important biomes of the South American continent characterize these Brazilian states: Amazon forest, Cerrado (Brazilian Savannah), and Pantanal. Besides their ecological relevance, these biomes historically lack intensive entomological surveys. Therefore, they are much underrepresented in the Brazilian natural history collections and in the scientific literature, which is further aggravated by the fact that these areas are being exponentially and rapidly converted to commercial lands. Our project involved over 90 collaborators from 24 different Brazilian institutions and one from Colombia among researchers, postdocs, graduate and undergraduate students, and technicians. We processed and analyzed nearly 300,000 specimens from ~60 families of Diptera collected with a large variety of methods in the sampled areas. Here, we provide a detailed overview of the genera and species diversity of 41 families treated. Our results point to a total of 2,130 species and 514 genera compiled and identified for the three states altogether, with an increase of 41% and 29% in the numbers of species and genera known for the three states combined, respectively. Overall, the 10 most species-rich families were Tachinidae, Cecidomyiidae, Tabanidae, Psychodidae, Sarcophagidae, Stratiomyidae, Bombyliidae, Syrphidae, Tephritidae, and Asilidae. The 10 most diverse in the number of genera were Tachinidae, Stratiomyidae, Asilidae, Mycetophilidae, Syrphidae, Tabanidae, Muscidae, Dolichopodidae, Sarcophagidae, and Chloropidae. So far, 111 scientific papers were published regarding taxonomic, phylogenetic, and biogeographical aspects of the studied families, with the description of 101 new species and three new genera. We expect that additional publications will result from this investigation because several specimens are now curated and being researched by specialists.

Abstract Introduction: The association of diabetes with subclinical thyroid diseases may increase the risk of cardiovascular diseases. We analyzed the association of subclinical hypothyroidism, diabetes, and both diseases with carotid Intima-Media Thickness (cIMT) as a surrogate maker for early cardiovascular disease in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Methods: Cross-sectional analysis with data from the 3rd visit (2017‒2019). Linear regression models were used to evaluate the association of subclinical hypothyroidism, diabetes and of both diseases with a cIMT presented as Beta (95% Confidence Interval – 95% CI) without adjustment, with adjustment for sociodemographic variables (Model 1) and multivariable adjustment (Model 1 more cardiovascular risk factors). We also used logistic regression models to analyze the Odds Ratio (OR) and 95% CI for the association of both diseases using cIMT > P75%. Results: After the exclusion of patients with previous cardiovascular disease, 5,077 participants with no diseases, 1578 with diabetes, 662 with subclinical hypothyroidism, and 234 with both diseases were included in the analysis. Linear regression models showed an association of cIMT with only diabetes (β = 0.019; 95% CI 0.012 to 0.027; p < 0.0001) and subclinical hypothyroidism more diabetes (β = 0.03; 95% CI 0.010‒0.047, p < 0.0001). The logistic regression model reported an association between diabetes and CIMT higher than P75% (OR = 1.49, 95% CI 1.30‒1.71). No interaction between diabetes and subclinical hypothyroidism was detected using cIMT respectively as a continuous (p = 0.29) or as a categorical variable (p = 0.92). Discussion: Diabetes was associated with higher cIMT values. However, no additive effect of subclinical hypothyroidism associated with diabetes over cIMT was detected.

Objetivos: Identificar los riesgos a los que están expuestos los niños, así como trabajos científicos que aborden la prevención de accidentes domésticos en la primera infancia. Métodos: Se trata de una revisión integrativa de la literatura realizada en las siguientes bases de datos: LILACS, MEDLINE, BDENF y SciELO. La evaluación, del nivel de evidencia de los artículos encontrados se obtuvo por medio del método Oxford Center for Evidence-based Medicine. Resultados: Diez artículos cumplieron con los criterios de búsqueda establecidos. Los accidentes domésticos que se destacaron en los artículos fueron: caídas, quemaduras, envenenamiento y caídas de televisión. Con relación al ambiente familiar, fue notorio que la mayoría de las familias en los estudios analizados eran de bajos ingresos. Conclusión: Los padres o responsables de los niños son fundamentales para prevenir accidentes domésticos por diversas causas. Además, el papel de los profesionales de la salud es fundamental para desarrollar o potencializar programas de prevención, principalmente dirigidos a personas en situación de vulnerabilidad social o económica, con el fin de capacitar a la población en la identificación y minimización de riesgos.

Abstract: Introduction: Early childhood is a phase marked by intense child development, with improved motor, cognitive and sensory skills. Given this, children are exposed to risks and, therefore, must redouble care to prevent accidents, especially at home. Aim: To identify the risks to which children are exposed, as well as scientific works that address the prevention of domestic accidents in early childhood. Methods: This is an integrative literature review conducted in the following databases: LILACS, MEDLINE, BDENF, and SciELO. The level of evidence of the articles found was assessed using the Oxford Center for Evidence-based Medicine method. Results: Ten articles met the established search criteria. The domestic accidents that stood out in the articles were: falls, burns, poisoning, and tipping over television sets. Regarding the family environment, it was clear that most families in the analyzed studies were of low income. Conclusion: Parents or guardians of children are essential to prevent domestic accidents from various causes. In addition, the role of health professionals is necessary to develop or enhance prevention programs, mainly aimed at the socially or economically vulnerable, to train the population in identifying and minimizing risks.

ABSTRACT Objective: To identify dietary patterns in an adult population and to verify the factors associated with them. Methods: We conducted a cross-sectional population-based household study with 1,574 individuals aged >20 years, of both sexes, living in Teresina and Picos, Piauí, Brazil. Sociodemographic, lifestyle and food consumption data were collected. Dietary patterns were obtained using principal component analysis. Results: There was a positive and significant association with the healthy eating pattern in women, elderly people, individuals with secondary and higher education and smokers. The white-meat pattern was positively associated with people without a partner and non-white skin, as well as with women, elderly people and smokers, and inversely with individuals with longer screen time and individuals with high school and college education. The unhealthy pattern was positively associated with individuals with excessive screen time and individuals with secondary and higher education, and inversely associated with individuals who were insufficiently active. Conclusion: Women, the elderly, individuals with a partner, non-smokers and active people have a healthier diet. However, men, smokers, with longer screen time and insufficiently active had a more inadequate diet, while the level of education showed contrasting results.

RESUMEN Objetivo: Identificar patrones dietéticos en una población de adultos y adultos mayoresy verificar los factores asociados a ellos. Métodos: Estudio transversal poblacional y domiciliario realizado en 1574 personas mayores de 20 años, de ambos sexos, residentes en Teresina y Picos, Piauí, Brasil. Se recogieron datos sociodemográficos, de estilo de vida y de consumo de alimentos. Los patrones dietéticos se obtuvieron mediante análisis de componentes principales. Resultados: Hubo asociación positiva y significativa con el patrón de alimentación saludable en mujeres, adultos mayores, individuos con educación secundaria y superior y fumadores. El patrón de carnes blancas se asoció positivamente con personas sin pareja y piel no blanca, así como con mujeres, personas mayores y fumadores, e inversamente con personas con mayor tiempo de pantalla y personas con educación secundaria y universitaria. El patrón insalubre se asoció positivamente con individuos con tiempo de pantalla excesivo y con individuos con educación secundaria y superior, y se asoció inversamente con individuos que eran insuficientemente activos. Conclusión: Las mujeres, los adultos mayores, las personas en pareja, los no fumadores y las personas activas tienen una dieta más saludable. Sin embargo, los hombres, fumadores, con mayor tiempo de pantalla e insuficientemente activos tenían una dieta más inadecuada, mientras que el nivel de educación mostró resultados contrastantes.

Abstract Schinus terebinthifolia Raddi green fruits essential oil (EO) was evaluated regarding its phytochemical profile, antimicrobial and cytotoxic activities, and toxicity. Gas chromatography with mass spectrometry was applied to identify its constituents, thereafter the minimum inhibitory concentration, minimum bactericidal and fungicidal concentrations, and its antibiofilm activity were evaluated. The EO cytotoxicity was assessed in tumor and non-tumor human cells, and in vivo toxicity was evaluated in a Galleria mellonella model. The major constituents of S. terebinthifolia EO were alpha-phellandrene and beta-phellandrene. The EO had a weak activity against all strains of Candida albicans (MIC 1000μg/mL) and had no activity against non-albicans strains, bacteria, and C. albicans biofilm. Cytostatic activity against all tumor cell lines was shown. Additionally, cell viability remained at EO concentrations up to 62.5 μg/mL. At 16 mg/mL, 50% hemolysis was observed, and it had low toxicity in vivo. Overall, the S. terebinthifolia EO was characterized by low antimicrobial and antibiofilm activities, with no evidence of toxicity to human tumor and non-tumor cells.

ABSTRACT Chagas disease is among the 21 neglected diseases according to the World Health Organization. This study aimed to investigate the morbidity and mortality distribution of Chagas disease for identifying areas with greater prevalences and deaths of the disease in Northeast Brazil. A population-based ecological study was performed from 2016 to 2018 using data on acute Chagas disease patients from the Disease Notification Information System, chronic cases from the Chagas Disease and the referral Heart Failure Outpatient Clinic in Pernambuco, and Chagas disease-related mortality from the Mortality Information System. The unit of analysis were Pernambuco State mesoregions. The indicators were spatialized into thematic maps on the occurrence and mortality of the disease per 100,000 inhabitants. No cases of acute disease were reported in the period analyzed. Data on 801 chronic Chagas disease patients were analyzed. The population showed an average age of 62 years, with female predominance. The most prevalent comorbidity was systemic arterial hypertension and cardiologic involvement without ventricular dysfunction. The average chronic disease occurrence rate was 3.2/ 100,000 people/ year. As for deaths in the mortality system; in total, 350 deaths were recorded, showing male predominance, age ≥ 60 years, and chronic disease with cardiac involvement as the main mortality cause. The annual average mortality proportion was 1.6/100,000 people. The chronic case distribution showed spatial heterogeneity, with the highest rates of chronic disease and deaths observed in two mesoregions, with the main cause of death being heart-related. This highlights the need for more specialized services in areas with higher burden of the disease to avoid delay in the patients’ care.

Abstract Objective: To evaluate the effectiveness of chewing gums containing CPP-ACP in remineralisation of demineralised enamel around orthodontic brackets. Material and Methods: Enamel blocks from 120 bovine incisors were used. The blocks were flattened and polished, followed by the development of incipient subsurface caries. The blocks have been subjected to a baseline microhardness analysis. Orthodontic brackets were bonded to the exposed area of the blocks, reserving an area for hardness analysis. An in situ crossover (three-way crossover phases of 21 days with an interval of one week between them), controlled, randomised and blind experimental model was used, with the participation of 12 volunteers divided into groups: G1 – negative control group, without chewing gum; G2 – conventional sugar-free chewing gum, without CPP-ACP (placebo); and G3 – sugar-free chewing gum with CPP-ACP. The following parameters were analysed: superficial linear (Ra), volumetric roughness (Sa), and superficial structural loss, which was indicated by Gap measurement (difference between the healthy and treated area). Statistical tests used were the Friedman, Wilcoxon and Shapiro-Wilk, Kruskal Wallis' nonparametric tests and ANOVA. Results: There was a significant reduction in enamel microhardness after demineralisation in all the groups (p<0.05). This deleterious effect was attenuated in the three groups after the final evaluation, although there were no statistical differences (p<0.05); however, the final values did not return to the baseline values (p<0.05). Conclusion: Chewing gum containing CPP-ACP did not promote in situ remineralisation of demineralised enamel around orthodontic brackets.

Abstract The topical glucocorticoid budesonide has been prescribed before and after sinus lift surgery as adjuvant drug treatment for maxillary sinus membrane inflammation. However, there is no study on the effects of budesonide on the regenerative process of bone grafting biomaterials. We investigated the effect of the association of budesonide with some biomaterials on the growth and differentiation capacity of pre-osteoblastic cells (MC3T3-E1 subclone 4). Xenogeneic (Bio-Oss and Bio-Gen) and synthetic hydroxyapatites (Osteogen, Bonesynth, and HAP-91) were tested in conditioned medium (1% w/v). The conditioned medium was then supplemented with budesonide (0.5% v/v). Cell viability was assessed using the MTT assay (48, 96, and 144 h), and mineralized nodules were quantified after 14 days of culture using the Alizarin Red Staining. Alkaline phosphatase activity was assessed through the release of thymolphthalein at day seven. All biomaterials showed little or no cytotoxicity. The Bio-Gen allowed significantly less growth than the control group regardless of the experimental time. Regarding differentiation potential of MC3T3-E1, the HAP-91-conditioned medium showed remarkable osteoinductive properties. In osteodifferentiation, the addition of budesonide favored the formation of mineral nodules when cells were cultured in medium conditioned with synthetic materials, whereas it weakened the mineralization potential of cells cultured in xenogeneic medium. Regardless of whether budesonide was added or not, Osteogen and Bio-Oss showed higher alkaline phosphatase activity than the other groups. Budesonide may improve bone formation when associated with synthetic biomaterials. Conversely, the presence of this glucocorticoid weakens the mineralization potential of pre-osteoblastic cells cultured with xenogeneic hydroxyapatites.
