A experiência de trabalhar no enfrentamento da Covid-19, em meio a um processo tenso, contraditório e com repercussões na própria saúde, constitui o contexto desta pesquisa, que tem o objetivo de entender o trabalho de Enfermagem na experiência de enfermeira(o)s da linha de frente contra a Covid-19, em Alagoas, Brasil. Trata-se de pesquisa qualitativa, com análise de conteúdo das histórias orais temáticas de seis enfermeiras que atuaram na linha de frente das cidades de Arapiraca e Maceió, estado de Alagoas, Brasil. As categorias temáticas que se destacaram na análise foram: desvalorização; ausência de estrutura física e de recursos para o trabalho; vínculo precário de trabalho; e relação entre sobrecarga, adoecimento e desgaste. Constatou-se que essas categorias compõem o que tem sido chamado de precarização do trabalho, já estabelecida anteriormente, mas amplificada na pandemia, a exemplo da experiência das trabalhadoras de Enfermagem.

The experience of working in the confrontation of Covid-19, amid tension, contradictions and impacts in the workers’ health constitutes the context of this research, with the objective of understanding the nursing work in the experience of frontline nurses against Covid-19, in Alagoas, Brazil. This is a qualitative research, using content analysis of the thematic oral histories of 6 nurses, who worked on the frontline in the cities of Arapiraca and Maceió, state of Alagoas, Brazil. The thematic categories emerging from the analysis were: devaluation; lack of physical structure and resources for work; precarious work bond; and the relationship between overload, illness, and wear and tear. It was found that these categories are encompassed by the term work precarization, previously established, but amplified in the pandemic, following the experience of nursing workers.

ABSTRACT Objective: To investigate working conditions in nursing when facing the Covid-19 pandemic, in light of aspects of precarious work. Methods: Cross-sectional study, with 131 nursing workers who worked against Covid-19 in hospitals in Alagoas State, Northeast Brazil. Data were collected online, using a workers’ health assessment questionnaire. The Chi -Square or Fisher’s Exact test and logistic regression were used. Results: among nursing workers, 71% had precarious contracts, 33.6% reported extended working hours and 23.7% were union members. In the multivariable analysis, having little hospital experience was a predictor for poor employment (OR= 2.408; 95%CI= 1.051-5.518). The predictor variables for lengthening the working day were being a nurse (OR= 3.824; 95%CI= 1.274-11.483); overtime (OR= 3.668; 95%CI= 1.009-13.333) and inadequate number of workers (OR= 10.872; 95%CI= 3.409-34.675). Being a nursing technician was a predictor of being a union member (OR= 8.967; 95%CI=2.560-31.410). Conclusions: The pandemic has accentuated the precariousness of working conditions in nursing professionals, especially among nurses.

RESUMEN Objetivo: Investigar las condiciones de trabajo de la enfermería para el afrontamiento del Covid-19, según la visión de la precarización del trabajo. Métodos: Es un estudio transversal realizado entre 131 trabajadoras(es) de enfermería que actuaron contra el Covid-19 en hospitales de Alagoas, Brasil. Los datos se recogieron online mediante un cuestionario de la salud de los trabajadores, con la Prueba X2 o Exacto de Fisher y regresión logística. Resultados: El 71% tenía contratos precarios, 33,6% declaró jornadas laborales prolongadas y 23,7% estaba sindicado. En el análisis multivariado, tener poca experiencia hospitalaria fue un factor predictivo del empleo precario (OR= 2,408; IC95%= 1,051-5,518). Las variables predictoras de jornadas laborales extendidas fueron: ser enfermera(o) (OR= 3,824; IC95%=1,274-11,483); horas extraordinarias (OR= 3,668; IC95%= 1,009-13,333) y número inadecuado de trabajadores (OR= 10,872; IC95% =3,409-34,675). Ser técnica(o) de enfermería fue un factor predictivo de estar sindicado (OR= 8,967; IC 95%= 2,560-31,410). Conclusiones: La pandemia acentuó la precarización de las condiciones de trabajo en la enfermería, principalmente entre las(os) enfermeras(os).

RESUMO Objetivo: Investigar as condições de trabalho em enfermagem no enfrentamento da pandemia de Covid-19, à luz de aspectos da precarização do trabalho. Métodos: Estudo transversal, com 131 trabalhadoras(es) da enfermagem que atuaram contra a Covid-19 em hospitais alagoanos, no Nordeste brasileiro. Os dados foram coletados online, por questionário de avaliação da saúde dos trabalhadores. Utilizaram-se o teste do Qui-Quadrado ou Exato de Fisher e a regressão logística. Resultados: Entre as(os) trabalhadoras(es), 71% tiveram contratos precários, 33,6% referiram ao prolongamento da jornada e 23,7% eram sindicalizadas(os). Na análise multivariável, ter pouca experiência hospitalar foi preditor para o vínculo precário (OR= 2,408; IC95%= 1,051-5,518).

Resumo Fundamento: A doença pelo novo coronavírus (COVID-19) está associada a manifestações clínicas cardiovasculares, incluindo a ocorrência de arritmias cardíacas. Objetivos: Avaliar a incidência de arritmias cardíacas (taquiarritmia atrial, bradiarritmia e taquicardia ventricular sustentada) e de parada cardiorrespiratória (PCR) em uma coorte de pacientes internados com COVID-19 em hospital universitário terciário. Métodos: Estudo de coorte retrospectivo realizado por meio de revisão dos registros de prontuário médico. Para comparação entre os grupos, foi considerado como estatisticamente significativo valor de P < 0,05. Resultados: Foram incluídos 241 pacientes consecutivos com diagnóstico de COVID-19 (idade média, 57,8 ± 15,0 anos; 51,5% homens; 80,5% de raça branca) e 35,3% com necessidade de ventilação mecânica invasiva (VM). A mortalidade geral foi de 26,6%, sendo de 58,8% entre aqueles em VM. Arritmias cardíacas ocorreram em 8,7% dos pacientes, sendo a mais comum taquiarritmia atrial (76,2%). Pacientes com arritmias apresentaram maior mortalidade, 52,4% versus 24,1% (p=0,005). Em análise multivariada, apenas a presença de insuficiência cardíaca foi associada a maior risco de arritmias ( hazard ratio , 11,9; IC 95%: 3,6-39,5; p<0,001). Durante a internação, 3,3% dos pacientes foram atendidos em PCR, com predomínio de ritmos não chocáveis. Todos os atendidos em PCR evoluíram com óbito durante a internação. Conclusão: A incidência de arritmias cardíacas em pacientes internados com COVID-19 em hospital terciário brasileiro foi de 8,7%, sendo a mais comum taquiarritmias atrial. A presença de insuficiência cardíaca foi associada a maior risco de arritmias. Pacientes com COVID-19 atendidos em PCR apresentam elevada mortalidade.

Abstract Background: The coronavirus disease 2019 (COVID-19) is associated with cardiovascular clinical manifestations, including cardiac arrhythmias. Objective: To assess the incidence of cardiac arrhythmias (atrial tachyarrhythmia, bradyarrhythmia, and sustained ventricular tachycardia) and cardiac arrest (CA) in a cohort of patients hospitalized with COVID-19 in a tertiary university-affiliated hospital. Methods: Cohort study with retrospective analysis of electronic medical records. For comparison between groups, a value of p <0.05 was considered statistically significant Results: We included 241 consecutive patients diagnosed with COVID-19 (mean age, 57.8 ± 15.0 years; 51.5% men; 80.5% white), 35.3% of whom received invasive mechanical ventilation (MV). The overall mortality was 26.6%, being 58.8% among those on MV. Cardiac arrhythmias were identified in 8.7% of the patients, the most common being atrial tachyarrhythmia (76.2%). Patients with arrhythmias had higher mortality (52.4% versus 24.1%, p = 0.005). On multivariate analysis, only the presence of heart failure (HF) was associated with a higher risk of arrhythmias (hazard ratio, 11.9; 95% CI: 3.6-39.5; p <0.001). During hospitalization, 3.3% of the patients experienced CA, with a predominance of non-shockable rhythms. All patients experiencing CA died during hospitalization. Conclusions: The incidence of cardiac arrhythmias in patients admitted with COVID-19 to a Brazilian tertiary hospital was 8.7%, and atrial tachyarrhythmia was the most common. Presence of HF was associated with an increased risk of arrhythmias. Patients with COVID-19 experiencing CA have high mortality.

Resumo Este trabalho objetivou analisar a tendência e a distribuição espacial da mortalidade de motociclistas em acidentes de transporte no estado de Alagoas. Trata-se de um estudo ecológico referente a todos os óbitos decorrentes de acidentes motociclísticos no estado no período 2001-2015. Os dados de mortalidade foram obtidos do Sistema de Informações sobre Mortalidade (SIM). As taxas de mortalidade foram calculadas e estratificadas por sexo. Para a análise de tendência, foi empregado o modelo de regressão por pontos de inflexão. Calculou-se a Variação Percentual Anual (VPA). Significância de 5%. Para a análise espacial, aplicou-se modelagem bayesiana empírica local, estatística de Moran e estatística de varredura espacial. Foram registrados 1.458 óbitos de motociclistas no período estudado, sendo 91,3% homens. Três comportamentos temporais foram observados nessa população: crescimento (2001-2005), padrão estacionário (2005-2013) e declínio a partir de 2013. As maiores taxas foram observadas no agreste e sertão. Cinco aglomerados espaciais foram evidenciados no que se refere à mortalidade geral e masculina, todos situados no agreste e sertão alagoanos. A modelagem mostrou redução da mortalidade a partir de 2013 e a análise espacial evidenciou que o problema é mais grave no interior do estado.

Abstract The scope of this work was to analyze the trend and distribution of mortality among motorcyclists in traffic accidents in the State of Alagoas. It involved an ecological study relating to all deaths resulting from motorcycle accidents in the state in the period from 2001 to 2015. Mortality data were obtained from the Mortality Information System (MIS). Mortality rates were calculated and stratified by gender. The joinpoint regression model was used for trend analysis and the Annual Percentage Variation (APV) was calculated with a significance rate of 5%. For the spatial analysis, local empirical Bayesian modeling and Moran statistics and spatial scanning statistics were applied. There were 1,458 deaths of motorcyclists in the period studied, 91.3% of which were men. Three temporal behaviors were observed in this population group: growth (2001-2005), stationary pattern (2005-2013) and decline from 2013 onwards. The highest rates were observed in the ‘agreste’ and ‘sertão’ regions of the state of Alagoas. Five spatial clusters were revealed with relation to general and male mortality, all located in the ‘agreste’ and ‘sertão’ hinterlands of Alagoas. The modeling showed a reduction of mortality from 2013 onwards and the spatial analysis revealed that the problem is more acute in the interior of the state.

Abstract The mucopolysaccharidoses (MPS) are a group of lysosomal storage disorders caused by 11 enzyme deficiencies, classified into seven types. Data on the birth prevalence of each MPS type are available for only a few countries, and the totality of cases may be underestimated. To determine the epidemiological profile of MPS in each Brazilian region, we analyzed data collected between 1982 and 2019 by a national reference laboratory and identified 1,652 patients. Using data between 1994 and 2018, the birth prevalence (by 100,000 live births) for MPS was 1.57. MPS II was the most common type of MPS in Brazil, and its birth prevalence was 0.48 (0.94 considering only male births). Regarding the number of cases per region, MPS II was the most frequent in the North and Center-West (followed by MPS VI), and also in the Southeast (followed by MPS I); MPS I and MPS II were the most common types in the South; and MPS VI was the most common in the Northeast (followed by MPS II). The differences observed in the relative frequencies of MPS types across Brazilian regions are likely linked to founder effect, endogamy, and consanguinity, but other factors may be present and need further investigation.

RESUMO Objetivo: Descrever o perfil das vítimas de tentativas de suicídio atendidas pelo Corpo de Bombeiros de um município do semiárido brasileiro. Métodos: Estudo transversal contendo dados do atendimento a vítimas de tentativas de suicídio, realizado pelos bombeiros militares do estado de Alagoas, no período de 1º de janeiro de 2000 a 31 de dezembro de 2017. Foram selecionadas as variáveis: sexo, idade, desfecho, intoxicação, uso de álcool, transtorno mental, estação do ano, dia da semana, horário, natureza da ocorrência e tempo de resposta, de transporte e total. Foram utilizados os testes qui-quadrado, exato de Fisher e Kruskal-Wallis. Resultados: Foram atendidas 144 vítimas de tentativas de suicídio. A frequência de atendimentos entre homens (n = 73; 50,7%) e mulheres (n = 71; 49,3%) foi semelhante. As mulheres apresentaram idade mais jovem (p < 0,001) e utilizaram o método da intoxicação (p < 0,001) duas vezes mais que os homens. A presença de transtorno mental (p = 0,04) foi mais comum entre os homens e o tempo consumido durante o atendimento pré-hospitalar foi maior entre eles, indicando que, possivelmente, as tentativas de suicídio cometidas por homens demandam maiores cuidados durante a assistência realizada pelos bombeiros. Conclusões: O perfil das vítimas de tentativas de suicídio apresentou frequência semelhante entre homens e mulheres, sendo as mulheres mais jovens. Nas mulheres, observou-se predomínio de intoxicações. Em homens, os transtornos mentais foram mais prevalentes. Além disso, fazem-se necessários o reconhecimento precoce dos casos de tentativas de suicídio, as principais formas de atuação e o preenchimento adequado das fichas de atendimento pré-hospitalar.

ABSTRACT Objective: To describe the profile of suicide attempts assisted by the Fire Department of a Brazilian semi-arid municipality. Methods: This is a cross-sectional study, containing data of care provided to victims of suicide attempts, conducted by the military firefighters of the state of Alagoas, from January 1, 2000 to December 31, 2017. The following variables were selected: sex, age, outcome, intoxication, alcohol use, mental disorder, season of the year, day of the week, schedule, nature of occurrence, response time, transportation time and total time. The chi-square, Fisher's exact test and Kruskal-Wallis tests were used. Results: Between 2000 and 2017, 144 victims of suicide attempts were cared. The frequency of care between men (n = 73; 50,7%) and women (n = 71; 49,3%) was similar. The women showed younger age (p < 0,001) and used the intoxication method (p < 0,001) twice as often as the men. The presence of mental disorder (p = 0,04) was more common among the men and the time consumed during prehospital care was higher among them, indicating that, possibly, suicide attempts committed by men require greater care for the assistance provided by firefighters. Conclusions: The profile of victims of suicide attempts showed a similar frequency between men and women, with younger women. In women, there was a predominance of intoxications. Besides that, mental disorders were more prevalent. However, it is necessary to early recognition of cases of suicide attempts, the main forms of action and the adequate completion of pre-hospital care forms.

Abstract Objectives: To characterize cases of suspected congenital disorders of glycosylation (CDG) investigated in a laboratory in southern Brazil using the transferrin isoelectric focusing TfIEF test from 2008 to 2017. Method: Observational, cross-sectional, retrospective study. The laboratory records of 1,546 individuals (median age = 36 months, 25–75 IQR = 10–108; males = 810) submitted to the TfIEF test during the period were reviewed. Results: Fifty-one individuals (3%) had an altered TfIEF pattern (5 ± 2.8 cases/year; median age = 24 months, 25–75 IQR = 11–57 months; males = 27, 53%). For 14 of them, data on diagnosis conclusion were available (classic galactosemia = 4; hereditary fructose intolerance = 4; peroxisomal diseases = 2; PMM2-CDG = 2; MPDU1-CDG = 1; SLC35A2-CDG = 1).Comparing the cases with the normal and altered TfIEF patterns, there was a higher prevalence of altered cases in the age group from 11 months to 3 years. There was an increase in the likelihood of change in TfIEF, especially in the presence of inverted nipples or liver disease. Conclusions: The data suggest that the investigation of a case with suspected CDG is a complex problem, being aggravated by the existence of other IEMs (inborn errors of metabolism) associated with altered TfIEF pattern and lack of access to confirmatory tests. The presence of inverted nipples and liver disease, especially in individuals aged 11 months to 3 years, should suggest the need for TfIEF investigation.

Resumo Objetivos: Caracterizar os casos com suspeita de CDG investigados em laboratório do sul do Brasil pelo exame de IEFTF de 2008 a 2017. Metodologia: Estudo observacional, transversal, retrospectivo. Foram revisadas as fichas laboratoriais de 1.546 indivíduos (mediana de idade = 36 meses, IQ 25-75 = 10-108; sexo masculino = 810) que fizeram o exame de IEFTF no período. Resultados: Cinquenta e um indivíduos (3%) apresentaram padrão alterado na IEFTF (5 ± 2,8 casos/ano; mediana de idade = 24 meses, IQ 25-75 = 11-57 meses; sexo masculino = 27, 53%). Para 14 deles, estavam disponíveis dados sobre a conclusão do diagnóstico (galactosemia clássica = 4; intolerância hereditária à frutose = 4; doenças peroxissomais = 2; PMM2-CDG = 2; MPDU1-CDG = 1; SLC35A2-CDG = 1). Comparando os casos com padrão normal e alterado na IEFTF, houve maior prevalência de casos alterados na faixa etária de 11 meses a 3 anos. Verificou-se um aumento na probabilidade de alteração na IEFTF principalmente na presença de mamilos invertidos ou de hepatopatia. Conclusões: Os nossos dados sugerem que a investigação de um caso com suspeita de CDG é complexa, é agravada pela existência de outros EIM associados a padrão alterado na IEFTF e pela falta de acesso a exames confirmatórios. A presença principalmente de mamilos invertidos e de hepatopatia em indivíduos na faixa etária de 11 meses a 3 anos deve sugerir a necessidade de investigação por IEFTF.

Abstract Neuronal ceroid lipofuscinoses (NCLs), also referred as “Batten disease”, are a group of thirteen rare genetic conditions, which are part of the lysosomal storage disorders. CLN type 2 (CLN2) is caused by the deficient activity of the tripeptidyl peptidase I (TPP1) enzyme, encoded by the TPP1 gene, most frequently leading to the classic late infantile phenotype. Nearly 140 CLN2-causing mutations have been described. In this case report, we describe the identification of a new disease-causing mutation and highlight the importance of appropriate laboratory investigation based on clinical suspicion. The collection of dried blood spots (DBS) on filter paper, which is a convenient sample, can be used to measure the TPP1 enzyme activity and detect CLN2-related mutations. Since the biochemical and genetic diagnoses are possible and as the disease progression is fast and the therapeutic window is short, the investigation of CLN2 should be always considered when this diagnostic hypothesis is raised in order to enable the patients to benefit from the specific pharmacological treatment.

Resumo O léxico da pobreza na Ordem Franciscana deve ser considerado em perspectiva com o vocabulário presente em outras temporalidades e em situações diversas ao longo da história do cristianismo. A análise da série histórica do uso da terminologia da pobreza é importante por afastar hipóteses ingênuas em torno de um suposto Francisco mítico e de uma Ordem Franciscana supostamente disruptiva; ao mesmo tempo, manifesta-se importante por iluminar aspectos particulares do éthos franciscano, aprofundando a capacidade de compreensão do historiador. Por essa razão, propomos aqui, a utilização da pobreza como categoria histórica, tendo como eixo da análise o fenômeno franciscano e estabelecendo, como fundamento metodológico, uma história global em sua relação dialética com as temporalidades particulares a partir das fontes documentais.

Abstract A lexical approach of the Franciscan Poverty must be placed in perspective with the general vocabulary found in different times and distinct situations over the Christian History. A long-term historical analysis is important to put away all the naïve hypothesis upon an alleged mythical Francis, as well as a supposed disruptive Franciscan Order; on the other hand, long-term historical analysis is relevant by bringing light to the uniqueness of the Franciscan éthos and, as consequence, by improving historian’s ability of comprehension. Thus, in this occasion, we propose the application of poverty as historical category for a focused analysis on Franciscan phenomenon; we also put forward the methodology of Global History that prescribes a dialectical interface between general and specific temporalities, with the intermediation of the documentary sources.

Abstract The objective was to evaluate the compressive strength (CS), diametral tensile strength (DTS), flexural strength (FS), and Knoop microhardness (KH) of different conventional restorative glass-ionomer cements (GICs) and to correlate these mechanical properties (MP) with the stabilization time (ST) of their chemical bonds. Eighteen GICs were tested: Bioglass [B], Chemfil Rock [CR], Equia Forte [EF], Gold Label 2 [GL2], Gold Label 9 [GL9], Glass Ionomer Cement II [GI], Ionglass [IG], Ion Z[ IZ], Ionomaster [IM], Ionofil Plus [IP], Ionostar Plus [IS], Ketac Molar Easymix [KM], Magic Glass [MG], Maxxion R [Ma], Riva Self Cure [R], Vidrion R [V], Vitro Fil [VF] and Vitro Molar [VM]. The mechanical strength tests were performed in a universal testing machine. KH readings were done with a diamond indenter. STs were examined by Fourier Transform Infrared spectroscopy (FTIR). Data were analyzed with ANOVA and Tukey test (p<0.05). The Spearman rank test was used to evaluate the dependence between the MPs and ST results. The highest MP values were EF, GL2, GL9, GI and KM and the lowest for MG, MA, B, VF and IM. The longest ST was for GL2 and the shortest was for B. ST correlated positively with MP. GICs with longer chemical bonds ST are generally stronger and the ST value obtained from FTIR was useful in predicting the strength of GICs tested.

Abstract Sandblasting is a common method to try to improve the Y-TZP/veneer bond strength of dental prostheses, however, it may put stress on zirconia surfaces and could accelerate the t→m phase transformation. Y-TZP sandblasting before sintering could be an alternative to improve surface roughness and bonding strength of veneering ceramic. Objectives. The aim of this study was to analyze the effect of Y-TZP pre-sintering sandblasting on surface roughness, phase transformation, and the Y-TZP/veneer shear bond strength. Material and Methods. The Y-TZP specimen surface underwent sandblasting with aluminum oxide (50 μm) pre-sintering (Z-PRE) and post-sintering (Z-POS). Z-CTR was not subjected to surface treatment. After ceramic veneer application, the specimens were subjected to shear bond testing. Surface roughness was analyzed by confocal microscopy. Y-TZP monoclinic and tetragonal phases were evaluated by micro-Raman spectroscopy. Shear bond strength and surface roughness data were analyzed by One-way ANOVA and Tukey tests (α=0.05). Differences in the wave numbers and the broadening bands of the Raman spectra were compared among groups. Results. Z-POS (9.73±5.36 MPa) and Z-PRE (7.94±2.52 MPa) showed the highest bond strength, significantly higher than that of Z-CTR (5.54±2.14 MPa). The Ra of Z-PRE (1.59±0.23 µm) was much greater and significantly different from that of Z-CTR (0.29±0.05 µm) and Z-POS (0.77±0.13 µm). All groups showed bands typical of the tetragonal (T) and monoclinic (M) phases. Y-TZP sandblasting before sintering resulted in rougher surfaces but did not increase the shear bond strength compared to post-sintering and increased surface defects. Conclusions. Surface treatment with Al3O2, regardless of the moment and application, improves the results of Y-TZP/veneer bonding and is not a specific cause of t→m transformation.

ABSTRACT Research involving the process of death regarding dysthanasia, which is defined as therapeutic obstinacy practiced with the aim to postpone death, and Orthothanasia, which is death in its natural process, without further treatment. The study aimed to recognize the perception that professionals of the health team working in an intensive care unit have about situations of Orthothanasia and Dysthanasia. The study was conducted in a university hospital. Data were collected through semi-structured interviews with 25 health professionals and submitted to thematic content analysis. Three related categories emerged: Seizing Orthothanasia and Dysthanasia; Realizing the decision-making context; Pondering Orthothanasia and Dysthanasia in the finitude of life. The perception of health professionals regarding Orthothanasia and Dysthanasia requires discussions that consider the ethical concepts involved in interventions adopted in the process of death in order to provide basis to the multidisciplinary team, family and patients in decision making at the end of life.
