Abstract To date, hydroxyurea is the only effective and safe drug that significantly reduces morbidity and mortality of individuals with Sickle cell disease. Twenty years of real-life experience has demonstrated that hydroxyurea reduces pain attacks, vaso-occlusive events, including acute chest syndrome, the number and duration of hospitalizations and the need for transfusion. The therapeutic success of hydroxyurea is directly linked to access to the drug, the dose used and adherence to treatment which, in part, is correlated to the availability of hydroxyurea. This consensus aims to reduce the number of mandatory exams needed to access the drug, prioritizing the requesting physician's report, without affecting patient safety. date disease reallife real life attacks vasoocclusive vaso occlusive events syndrome transfusion which part physicians physician s report safety

Aim The main purpose of this study was to conduct a narrative review investigating the possible relationship between permanent maxillary anterior teeth and anthropometric facial parameters in different populations. Methods Searches were performed in the PubMed, BVS (Biblioteca Virtual em Saúde) and SciELO databases to identify relevant scientific articles using the following search terms: “maxillary anterior teeth”, “facial measurements” and “anthropometry”, in such a way that 218 publications were found. After application of inclusion and exclusion criteria, 13 publications remained for full-text reading. Results All studies involved male and female samples and it was notorious that male measurements were unanimously higher than those obtained in the opposite sex. The age of the analyzed participants ranged from 17 to 60 years; however, a mean age of 18 to 25 years was the most investigated in literature. In addition, facial measurements including the bizygomatic width, interpupillary distance, intercanthal distance, interalar width and intercommissural width have been proposed to help determine the correct size of anterior teeth. Conclusion It was concluded that despite the limited number of studies, some factors that influence dental and facial dimensions, such as sex and age, can be identified. However, there is no standardization of the facial or dental parameters used in the studies, a fact that makes it difficult to establish a universal ratio for clinical dental practice. populations PubMed Biblioteca Saúde terms teeth, , teeth” anthropometry, anthropometry “anthropometry” 21 found criteria 1 fulltext full text reading 6 however 2 literature addition distance dimensions identified However practice “anthropometry

ABSTRACT OBJECTIVE To evaluate the evolution of the dietary patterns of adolescents in the northeast region of Brazil. METHODS Secondary analysis of data from the Pesquisa de Orçamentos Familiares (POF – Household Budget Surveys), collected by the Brazilian Institute of Geography and Statistics (IBGE) in the years 2008–2009 and 2017–2018. A total of 3,095 adolescents were evaluated in 2008–2009 and 3,015 in 2017–2018. Food consumption was assessed using two dietary records in 2008–2009 and two 24-hour recalls in 2017–2018, applied on non-consecutive days. Based on these data, principal components factor analysis (PCFA) was performed, followed by orthogonal rotation of the varimax type, to derive dietary patterns, stratified by sex. The results were described as means or percentage frequencies, with their respective 95% confidence intervals. RESULTS Three main dietary patterns were identified among adolescents from the northeast region of Brazil. Among boys, in 2008–2009, the patterns were called snacks, traditional Brazilian, and coffee; and in 2017–2018, traditional Brazilian, snacks, and mixed, in this order of representativeness of the group’s eating habits. Among female adolescents, in 2008–2009, the patterns were snacks, traditional Brazilian, and coffee; and in 2017–2018, traditional Brazilian, snacks, and processed meats. CONCLUSION The dietary patterns identified in 2008–2009 and 2017–2018 were similar in both genders; however, the snacks pattern, which explained most of the data variability in 2008–2009, was replaced by the traditional Brazilian.

ABSTRACT The present article focuses on the research that originated the book The Production of School Failure: Stories of Submission and Rebellion, based on the memories of the researchers. This work is considered a landmark because it makes sharp criticisms of the hegemonic practices of Psychology and Education and proposes radical theoretical and methodological ruptures in research on Brazilian public education. The article shares theoretical and methodological reflections that guided the meetings and interviews with Maria Helena Souza Patto and the three auxiliary researchers of the classic book. Once the participants’ previous trajectory is retrieved, a sewing of the researchers’ memories with the reflections registered in the book regarding the procedure developed brings details that were not highlighted in the publication and that were fundamental for the study of daily practices.

ABSTRACT Objectives: To assess the molecular profile of follicular cell-derived thyroid carcinomas (FCDTCs) and correlate the identified mutations with the clinical and pathological features of the affected patients. Materials and methods: Cross-sectional study of tumor samples from 100 adult patients diagnosed with FCDTC between 2010 and 2019. The patients’ clinical and pathological data were collected. Genomic DNA was extracted from formalin-fixed, paraffin-embedded (FFPE) tumors using the ReliaPrep FFPE gDNA Miniprep System. Genotyping of target genomic regions (KRAS, NRAS, BRAF, EGFR, and PIK3CA) was performed using the AmpliSeq panel, while sequencing was performed on the iSeq 100 platform. Results: The patients’ mean age was 39 years. In all, 82% of the tumors were classic papillary thyroid carcinomas. Overall, 54 (54%) tumor samples yielded satisfactory results on next-generation sequencing (NGS), of which 31 harbored mutations. BRAF gene mutations were the most frequent, with the BRAFV600E mutation present in 10 tumors. Seven tumors had BRAFNON-V600E mutations not previously described in FCDTCs (G464E, G464R, G466E, S467L, G469E, G596D, and the T599Ifs*10 deletion) but described in other types of cancer (i.e., skin/melanoma, lung, colorectal, and others). One tumor had a previously reported BRAFA598V mutation. EGFR gene mutations were found in 16 (29%) and KRAS or NRAS alterations in 8 (14%) of the 54 tumors analyzed. Conclusion: We described herein seven non-hotspot/novel variants in the BRAF gene, highlighting their potential role in expanding our understanding of FCDTC genetics.

Abstract This article addresses the world of healthcare work, especially in the Brazilian Unified Healthcare System (SUS) in the context of the COVID-19 pandemic in Brazil. This study used data from the following surveys: “Working conditions of health professionals in the context of COVID-19 in Brazil” and “The Invisible health workers: working conditions and mental health in the context of COVID-19 in Brazil”. Data analysis proves that the pandemic highlighted existing structural problems within SUS, involving the issue of healthcare workforce (HWF) management, which can be interpreted as another reflection of the socioeconomic inequalities that already exist in the country. This article highlights: the reduced provision of permanent education, the regulation of hybrid care, precariousness, a lack of protection in the work environment, as well as fragile biosecurity leading to tragic rates of illness and death of health workers. Our study concludes by showing the importance of formulating public policies in the scope of education and work management in SUS that ensure the discussion on hybrid care as a new way of acting without losing quality, together with the need to review issues related to permanent education, protection, valuation, and reduction of inequalities pointed out among the professional contingents analyzed in this article.

Abstract The present article analyzed the process of precarious work relations in the health sector, demonstrating how this situation generated illness and suffering among workers. The text sought to register how the institutional adoption of neoliberal economic conceptions, of the reduction of State social policies, coupled with a history of cultural rejection of labor rights, provided the attraction of mechanisms of precarious work for the public sector, notably, the outsourcing of labor and the provision of services. In a second moment, the text points out the legal improprieties committed, presenting the consequences of the weakening of the legal bond in the working conditions of these workers, mainly regarding working hours and remuneration, also highlighting how much the dissemination of these links represented a factor of a general reduction in wages and labor and social security rights in the sector. Data from Fiocruz surveys on working conditions during the pandemic were also presented. The article concludes by showing the urgency of rescuing the legal labor institutes that were abandoned in the historical path studied in order to guide the public health policies in a new direction. sector workers conceptions notably services moment committed remuneration presented direction

Resumen Objetivo: Describir la epidemiología de los accidentes de trabajo con exposición a material biológico entre los enfermeros. Método: Estudio epidemiológico, descriptivo y retrospectivo, que incluyó 102 casos de accidentes de trabajo en enfermeros. Resultados: Hubo predominio del sexo femenino (77,4 %); rango de edad de 20 a 29 años (58,8 %); raza/color de piel morena (53,9 %). La mayoría de los trabajadores tenían vinculo de trabajo formal (64,7 %). En el 68,2% de los casos, la circunstancia del accidente fue la exposición percutánea y, en el 71,5 %, por materia orgánica - sangre; el agente principal fue la aguja del lumen (66,6 %); el 44,1 % llevaba guantes y el 35,9 % mascarilla en el momento del accidente; el 43,2 % tenía el campo de evolución del caso rellenado como ignorado/en blanco. Conclusión: Los accidentes son en su mayoría el resultado de acciones de la práctica diaria, como los pinchazos, aunque estos profesionales hacen uso de equipos de protección. Por lo tanto, la educación permanente sobre la seguridad en el trabajo, combinada con la concientización sobre la relevancia de la notificación, es un desafío para el ejercicio de una práctica segura.

Abstract Objective: To describe the epidemiology of occupational accidents with exposure to biological material among nurses. Method: Epidemiological, descriptive and retrospective study, involving 102 cases of occupational accidents among nurses. Results: There was a predominance of females (77.4 %); 20 to 29 years of age (58.8 %); and brown skin color (53.9 %). Most of the workers had a work registration (64.7 %). In 68.2% of the cases, the circumstance of the accident was percutaneous exposure and, in 71.5%, by organic material - blood; the main agent was the lumen needle (66.6 %); 44.1 % were wearing gloves and 35.9 % were wearing masks at the time of the accident; (43.2 %) had the case evolution field filled in as ignored/white. Conclusion: Accidents are mostly the result of daily practice actions, such as punctures, although these professionals use protective equipment. Therefore, continuing education on safety at work, coupled with awareness about the relevance of notification is a challenge for the exercise of a safe practice.
