The NixCu(1-x)Fe2O4 (x = 0, 0.2, 0.8, 1) mixed nickel and copper ferrites were synthesized using the EDTA-Citrate complexation method and calcined at 700°C. The structure, properties and characterization of the samples were analyzed by DRX, Rietveld refinement, SEM, and DRE UV-Vis, indicating the phase formation of tetragonal (CuFe2O4 and Ni0.2Cu0.8Fe2O4) and cubic (Ni0.8Cu0.2Fe2O4 and NiFe2O4). The materials exhibited morphologies suitable for photocatalytic applications and a UV-Vis absorption range near 2 eV as expected for spinel ferrites. These materials were evaluated as photocatalysts for the degradation of Rhodamine B dye under heterogeneous photocatalysis conditions, simulating solar light irradiation, air injection, and different pH levels (2, 6, and 10). The results showed that the catalytic efficiency was higher for samples with a higher copper content and in a basic medium. Therefore, NixCu(1-x)Fe2O4 mixed ferrites have promising potential as photocatalysts.

Resumen Introducción: Los homicidios son causas importantes de mortalidad en el mundo, especialmente en Brasil, que representa aproximadamente dos tercios de las muertes por causas externas y el tercer lugar entre las causas de muerte en el país. Materiales Y métodos: Estudio retrospectivo sobre la ocurrencia de causas de muertes violentas ocurridas en diferentes regiones de Municipio de São Paulo de 2000 a 2014 según el Sistema de Información de Mortalidad de la Secretaría de Salud Municipal. Se calculó el coeficiente estandarizado (CP) para la ocurrencia de homicidios y las tasas de riesgo según la población y el sexo masculino. Resultados: De 11.981 casos, el CP mostró que las regiones sur y este mostraron un aumento en la ocurrencia de homicidios entre los años 2000 y 2005 en comparación con los años 2010 y 2014. Considerando la suma del CP en los 15 años, Es posible observar la mayor ocurrencia de homicidios en las regiones sur y oriente de la ciudad de São Paulo, sin embargo, con una reducción entre los años 2010 y 2014. En cuanto a la tasa de riesgo relativo de homicidio, la región norte tuvo tasas más altas entre 2000 y 2005. Al considerar el género masculino, la región oeste mostró un aumento en la tasa de riesgo entre 2000 y 2005. Para los años 2010 la tasa de riesgo se mantuvo elevada para las regiones: norte (1,14) y este (1,15), mientras que para los hombres la tasa de riesgo (0,91) se mantuvo alta para la región sur. En 2014, la tasa de riesgo más alta (1,18) se trasladó a la región occidental, mientras que para los hombres la tasa de riesgo más alta se dirigió a la región central (0,92). Conclusiones: Se mantuvieron altas tasas de ocurrencia de homicidios para las regiones sur y oriente de la ciudad de São Paulo durante los últimos 15 años. La tasa de riesgo difiere entre las regiones de la ciudad de São Paulo, destacando la región norte entre los años 2000, 2005 y 2010 y la región occidental en 2014. El género masculino influye en las tasas de riesgo entre regiones, especialmente la región occidental entre 2000 y 2005, la región sur en 2010 y la región central en 2014, mostrando su influencia en la ocurrencia de homicidios.

Abstract Introduction : Homicides are important causes of mortality in the world, especially in Brazil, which represents approximately two thirds of deaths from external causes and the third place among the causes of death in the country. Methods: Retrospective study on the occurrence of causes of violent deaths occurring in different regions of the city of São Paulo from 2000 to 2014 according to the Mortality Information System of the Municipal Health Secretariat. The standardized coefficient (CP) for the occurrence of homicides and risk rates according to population and male gender were calculated. Results: The PC showed that the south and east regions had increased homicide occurrence between 2000 and 2005 when compared to the years 2010 and 2014. Considering the sum of the PC over the 15 years can be observed the highest occurrence of homicide. in the southern and eastern regions of São Paulo, however, with a reduction in occurrence between 2010 and 2014. Regarding the relative risk rate for homicide, the northern region presented higher rates between 2000 and 2005. When considering gender male population, the western region showed an increase in the risk rate between 2000 and 2005. For 2010, the risk rate remained higher for the northern (1.14) and eastern (1.15) regions, while for the male gender. For men, the risk rate (0.91) remained high for the southern region. In 2014 the highest risk rate (1.18) moved to the western region while for males the highest risk rate was directed to the central region (0.92). Conclusions: High homicide rates have remained in the southern and eastern regions of the city of São Paulo over the past 15 years. The risk rate differs between the regions of the city of São Paulo, highlighting the northern region between 2000, 2005 and 2010 and the western region in 2014. The male gender influences the risk rates between the regions, especially the western region between 2000 and 2005, the southern region in 2010 and the central region in 2014, showing their influence on homicide.

RESUMO O DC de Neuroimunologia da ABN e o BCTRIMS trazem, nesse documento, as recomendações sobre vacinação da população com doenças desmielinizantes do sistema nervoso central (SNC) contra infecções em geral e contra o coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2), causador da COVID-19. Destaca-se a gravidade do atual momento frente ao avanço da COVID-19 em nosso País, o que torna mais evidente e importante a criação de guia de referência para orientação aos médicos, pacientes e autoridades de saúde pública quanto à vacinação, meio efetivo e seguro no controle de determinadas doenças infecciosa. O DCNI/ABN e o BCTRIMS recomendam que os pacientes com doenças desmielinizantes do SNC (ex., EM e NMOSD) sejam constantemente monitorados, quanto a atualização do seu calendário vacinal, especialmente, no início ou antes da mudança do tratamento com uma droga modificadora de doença (DMD). É importante também salientar que as vacinas são seguras e os médicos devem estimular o seu uso em todos os pacientes. Evidentemente, deve ser dada especial atenção às vacinas com vírus vivos atenuados. Por fim, é importante que os médicos verifiquem qual DMD o paciente está em uso e quando foi feita a sua última dose, pois cada fármaco pode interagir de forma diferente com a indução da resposta imune.

ABSTRACT The Scientific Department of Neuroimmunology of the Brazilian Academy of Neurology (DCNI/ABN) and Brazilian Committee for Treatment and Research in Multiple Sclerosis and Neuroimmunological Diseases (BCTRIMS) provide recommendations in this document for vaccination of the population with demyelinating diseases of the central nervous system (CNS) against infections in general and against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19. We emphasize the seriousness of the current situation in view of the spread of COVID-19 in our country. Therefore, reference guides on vaccination for clinicians, patients, and public health authorities are particularly important to prevent some infectious diseases. The DCNI/ABN and BCTRIMS recommend that patients with CNS demyelinating diseases (e.g., MS and NMOSD) be continually monitored for updates to their vaccination schedule, especially at the beginning or before a change in treatment with a disease modifying drug (DMD). It is also important to note that vaccines are safe, and physicians should encourage their use in all patients. Clearly, special care should be taken when live attenuated viruses are involved. Finally, it is important for physicians to verify which DMD the patient is receiving and when the last dose was taken, as each drug may affect the induction of immune response differently.

RESUMO Antecedentes: A catastrofização é um aspecto psicológico da dor, alterando sua percepção e expressão. Objetivos: Investigar o fenômeno da catastrofização na enxaqueca. Métodos: Pesquisa online com indivíduos que sofrem de crises de enxaqueca pelo menos duas vezes por mês, por pelo menos um ano. O sigilo foi assegurado. O participante dava detalhes de sua dor de cabeça (incluindo escala de dor analógica visual) e respondeu à Escala de Ansiedade e Depressão Hospitalar e à Escala de Catastrofização. Resultados: A pesquisa identificou 242 indivíduos com ataques de enxaqueca pelo menos duas vezes por mês. Os escores medianos observados neste grupo de indivíduos foram 7 para dor, 11 para ansiedade, 7 para depressão e 2 para catastrofização. Catastrofização não teve correlação com a duração (p=0,78) ou intensidade (p=0,79) da dor na crise de enxaqueca. Não houve correlação entre catastrofização e frequência de crises (p=0,91) ou quantidade mensal de medicação usada para tratar a cefaleia (p=0,85). Foram identificados escores elevados para catastrofização (≥3,0) em um terço dos participantes. Esses escores elevados não foram associados à idade, duração da dor de cabeça, gravidade da dor, frequência de ataques e traços de depressão ou de ansiedade. Houve moderada associação entre casos com concomitante depressão e ansiedade e catastrofização. Conclusões: A catastrofização parece ser um traço do indivíduo e parece não estar relacionada às características da enxaqueca.

ABSTRACT Background: Catastrophization is a psychological aspect of pain that alters its perception and expression. Objective: To investigate the feature of catastrophization in migraine. Methods: An online survey of individuals suffering from migraine attacks at least twice a month, for at least one year was carried out. Confidentiality was assured and participants gave details of their headache (including a visual analogue pain scale) and answered the Hospital Anxiety and Depression Scale and the Catastrophization Scale questionnaires. Results: The survey included 242 individuals with migraine attacks at least twice a month. The median scores observed in this group of individuals were 7 for pain, 11 for anxiety, 7 for depression, and 2 for catastrophization. Catastrophization had no correlation with the duration (p=0.78) or intensity (p=0.79) of the migraine. There was no correlation between catastrophization and headache frequency (p=0.91) or the monthly amount of headache medication taken (p=0.85). High scores for catastrophization (≥3.0) were identified in one third of the participants. These high scores were not associated with age, headache duration, pain severity, frequency of attacks, or traits of depression or anxiety. There was a moderate association between both depression and anxiety traits with catastrophization. Conclusions: Catastrophization seems to be a trait of the individual and appears to be unrelated to the characteristics of the migraine.

This work aims to evaluate the possible relations between the confirmed daily cases of COVID-19 and the environmental parameters for the Cuiabá-Várzea Grande conurbation in the state of Mato Grosso, Brazil. The data sets used to cover the rainy-dry periods, from January to December 2020, were achieved from a database of government institutions, and processed through the Spearman correlation test. Our results showed that atmospheric pressure and fire radiative power has a significant positive correlation, suggesting that these parameters favor the transmission of COVID-19. On the other hand, the relative humidity of the air and the total column of water vapor showed a significant negative correlation with the number of confirmed daily cases of COVID-19, which indicates that the water vapor present in the atmosphere acts in the regulation of virus transmission. Thus, taking into account the results obtained, there is a need for collaborative policies and measures among the three spheres of executive power in Brazil, to act in the surveillance of fire cases, which can favor the transmission of COVID-19. In addition, prevention and protection measures aimed at reducing the spread of coronavirus continue to be indispensable.

Resumo Os sintomas da doença renal crônica (DRC) são frequentemente inespecíficos ou ausentes nos estágios iniciais desta doença. Desta forma, existe uma demanda para o desenvolvimento de plataformas com baixo custo, não-invasivas e com alta acurácia para o diagnóstico da DRC. Nós hipotetizamos que o nível dos componentes salivares se alteram pela DRC, o que pode ser clinicamente utilizado para discriminar pacientes portadores de DRC de indivíduos controles. O objetivo deste estudo foi comparar componentes salivares entre pacientes portadores de DRC e sujeitos controles utilizando um sistema de reflectância total atenuada com espectroscopia infravermelho com transformada em Fourier (ATR-FTIR). O poder preditivo dos componentes salivares foi avaliado pela curva característica de operação do receptor (ROC). Diversos componentes salivares foram identificados e 4 destes apresentaram diferença na expressão (p<0,05) entre DRC e sujeitos controles. O modos vibracionais do tiocianato (2052 cm-1) e de fosfolipídeos/carbohidratos (924 cm-1) utilizando espectros originais e da segunda-derivada pelo ATR-FTIR podem potencialmente ser utilizados como biomarcadores salivares para discriminar a DRC de sujeitos controles. A combinação dos espectros originais e da segunda-derivada pelo ATR-FTIR do modo vibracional 924 cm-1 pode apresentar sensibilidade de 92.8% e especificidade de 85.7% para a detecção da DRC. Este estudo indicou que modos vibracionais da saliva pela plataforma ATR-FTIR podem ser uma ferramenta auxiliar no diagnóstico da DRC.

Abstract The symptoms of chronic kidney disease (CKD) are often not specific or absent in the early stages of this illness. Therefore, there is a demand for developing low cost, non-invasive and highly accurate platforms for CKD diagnostics. We hypothesized that the level of specifics salivary components changes when CKD is emplace, which could be clinically used to discriminate CKD patients from healthy subjects. The present study aimed to compare salivary components between CKD patients and matched control subjects by using attenuated total reflection-Fourier Transform Infrared (ATR-FTIR) spectroscopy. The predictive power of salivary components was evaluated by receiver operating characteristic (ROC) curves. Several components were identified, and 4 of them showed different expression (p<0.05) between CKD and control subjects. Thiocyanate (SCN-, 2052 cm-1) and phospholipids/carbohydrates (924 cm-1) vibrational modes using original and second-derivative spectra by ATR-FTIR could potentially be used as salivary biomarkers to differentiate CKD than control subjects. The combination of original and second-derivative spectra by ATR-FTIR of 924 cm-1 vibrational modes could reach 92.8% sensitivity and 85.7% specificity for CKD detection. Despite, the limitation of our investigation, the acquired data indicates that salivary vibrational modes by ATR-FTIR platform should be further explored as an auxiliary diagnostic tool for CKD.

Conclusão O estudo mostrou que pessoas que convivem com HIV aderem a TARV, porém com média adesão e os principais fatores associados a esse resultado foram a orientação sexual e o tempo de diagnóstico.

Abstract Objective To identify the factors associated to non-compliance with antiretroviral treatment in HIV / AIDS patients at a reference hospital in Manaus. Methods Hospital-based, quantitative, cross-sectional study developed with 100 participants with HIV / AIDS in outpatient follow-up. For the data collection, the self-administered “Questionnaire for the evaluation of compliance with antiretroviral treatment in people with HIV / AIDS” (CEAT-VIH) was used. Descriptive analysis was performed using the Pearson chi-square to obtain the p-value. Results Male participants were predominant (57%), age between 40 and 59 years (34%), secondary education (49%), without employment bond (84%), monthly income of one to three minimum wages (54% ), unmarried (47%), heterosexual (76%), with sexual partner (56%), without active sexual life (61%), time since diagnosis between six months and five years (59%), no hospitalization (%). The predominant level of compliance was medium compliance (85%). The sociodemographic variables that revealed a statistically significant association with ARVT were sexual orientation (p = 0.010) and time since diagnosis (p = 0.035). Conclusion The study showed that people living with HIV comply with ARVT, but with medium compliance. The main factors associated with this result were sexual orientation and time since diagnosis.

RESUMO Esclerose múltipla (EM) é uma complexa doença autoimune e neurodegenerativa do sistema nervoso central. Uma vez que EM afeta principalmente mulheres em idade fértil, assuntos relacionados à gravidez frequentemente surgem na prática diária. O presente estudo avaliou o uso pós-parto de imunoglobulina (IVIG) na EM. Métodos Os autores individualmente pesquisaram as bases de dados PubMed, Medline, EMBASE, Cochrane, SciELO, LILACS, e Google Scholar usando os termos “multiple sclerosis” OR “MS” AND “pregnancy” OR “gestation” OR “partum” OR “post-partum” OR “puerperium” AND “immunoglobulin”. Resultados A pesquisa inicial retornou 321 artigos. Havia 11 artigos elegíveis para a revisão. No total, havia relato de 380 pacientes que receberam IVIG após a gravidez visando reduzir o número de surtos. O número necessário para tratar não ajustado foi 6,3 para análise quantitativa e 5,8 para análise qualitativa. Conclusão O efeito terapêutico da IVIG para prevenção dos surtos pós-parto na EM não pôde ser claramente estabelecida nesta meta-análise.

ABSTRACT Multiple sclerosis (MS) is a complex autoimmune and neurodegenerative disease of the central nervous system. Since MS affects mostly fertile women, pregnancy issues often arise in daily practice. The present study assessed the use of postpartum intravenous immunoglobulin (IVIG) in MS. Methods The authors individually searched for records using PubMed, Medline, EMBASE, Cochrane, SciELO, LILACS, and Google Scholar, using the terms “multiple sclerosis” OR “MS” AND “pregnancy” OR “gestation” OR “partum” OR “post-partum” OR “puerperium” AND “immunoglobulin”. Results The initial search returned 321 papers. There were 11 eligible articles selected for the review. In total, 380 patients had received post-natal IVIG to reduce the number of postpartum relapses. The unadjusted number needed to treat was 6.3 for the quantitative and 5.8 for the qualitative analyses. Conclusion The therapeutic effect of IVIG for prevention of postnatal relapses in MS could not clearly be established in this meta-analysis.

RESUMO Augusta Marie Déjerine-Klumpke (1859-1927) foi uma formidável neurologista, neuroanatomista e pesquisadora na França. Uma das primeiras mulheres aceitas para estágios médicos internos e externos ao hospital, e pesquisa em Paris, Augusta fez seu nome estudando e ensinando anatomia, histologia e dissecção, participando de atividades clínicas em neurologia, obstetrícia, pediatria e trauma neurológico, participando de necrópsias, e escrevendo artigos científicos e capítulos de livros. Sua principal pesquisa em neurologia lhe rendeu um epônimo para a avulsão da raiz inferior do plexo braquial (paralisia de Klumpke). Casada com seu professor, o notável Dr. Joseph Jules Déjerine, Augusta continuou sua carreira e se tornou a primeira mulher presidente da Sociedade Francesa de Neurologia.

ABSTRACT Augusta Marie Déjerine-Klumpke (1859-1927) was a formidable neurologist, neuroanatomist and researcher in France. One of the first women to be accepted for medical internship, externship and research in Paris, Augusta made her name studying and teaching anatomy, histology and dissection, attending clinical activities in neurology, obstetrics, pediatrics and neurologic trauma, performing necropsies, and writing scientific papers and book chapters. Her main research in neurology awarded her an eponym for the avulsion of the lowest root of the brachial plexus (Klumpke's palsy). Married to her professor, the remarkable Dr. Joseph Jules Déjerine, Augusta continued her career and became the first female president of the French Society of Neurology.

RESUMO Mary Broadfoot Walker foi uma médica escocesa que em 1935 descreveu em grande detalhe o efeito de uma droga anticolinesterásica (fisostigmina) nos sinais e sintomas da myasthenia gravis. Um filme original com cinco minutos de duração está disponível online e a reação cética dos colegas médicos contemporâneos de Mary é compreensível dado o drástico efeito terapêutico mostrado neste filme. O que Mary Walker nos ensinou mais de oito décadas atrás continua a ser a base de um teste diagnóstico farmacológico e do tratamento da myasthenia gravis.

ABSTRACT Mary Broadfoot Walker was a Scottish physician who, in 1935, described in great detail the effect of an anticholinesterase drug (physostigmine) on the signs and symptoms of myasthenia gravis. An original five-minutes movie is available online and the skepticism of her contemporary British medical doctors is understandable when the drastic effect of the treatment is shown in this movie. What Mary Walker taught us, more than eight decades ago, about myasthenia gravis continues to be the basis of a pharmacological diagnostic test and treatment of this disease.

RESUMO Objetivo: Vitamina D assumiu um papel central na pesquisa e tratamento da esclerose múltipla (EM). O objetivo deste estudo foi avaliar os níveis séricos de vitamina D de pacientes com EM e controles que residem em uma área tropical. Métodos: Foram analisados dados de 535 pacientes com EM e 350 indivíduos controle em 14 cidades próximas ao Trópico de Capricórnio. Resultados: O valor médio da determinação de 25-OH vitamina D foi 26,07 ± 10,27 ng/mL para controles e 28,03 ± 12,19 ng/mL para pacientes com EM. Não houve correlação entre os níveis de vitamina D e o grau de incapacidade ao longo da duração da doença. Conclusão: Pelo menos na região que cerca o Trópico de Capricórnio, os níveis séricos de vitamina D estão entre valores de 20 a 30 ng/mL tanto para controles quanto para pacientes com EM.

ABSTRACT Objective: Vitamin D has taken center stage in research and treatment of multiple sclerosis (MS). The objective of the present study was to assess the serum vitamin D levels of a large population of patients with MS and controls living in a restricted tropical area. Methods: Data from 535 patients with MS and 350 control subjects were obtained from 14 cities around the Tropic of Capricorn. Results: The mean serum 25-OH vitamin D level was 26.07 ± 10.27 ng/mL for the control subjects, and 28.03 ± 12.19 ng/mL for patients with MS. No correlation was observed between vitamin D levels and the disability of patients over the disease duration. Conclusion: At least for the region around the Tropic of Capricorn, serum levels of vitamin D typically are within the range of 20 to 30 ng/mL for controls and patients with MS.

Abstract INTRODUCTION The relationships between monocytes and lymphocytes through MHC class II molecules and costimulatory, are of utmost importance for the production of an efficient immune response. In this work, we assessed the expression of surface molecules CD80 and CD86 on CD14+HLA-DR+ monocytes from patients with Chagas disease. METHODS: The study population consisted of 31 patients with chronic clinical forms of Chagas disease. Patient blood samples were cultured in the presence of recombinant cytoplasmic repetitive antigen (CRA) and flagellar repetitive antigen (FRA). RESULTS: We found considerable differences in the expression profile of surface molecules involved in antigen presentation. CONCLUSIONS: CRA and FRA may contribute to host immune response evasion by Trypanozoma cruzi.

Objetivo: Relatar os resultados de uma oficina de trabalho sobre programas e centros de atenção a asmáticos (PCAAs) no Brasil para que possam servir como instrumento para melhoria e avanço dos PCAAs existentes e criação de novos. Métodos: A oficina de trabalho constituiu-se de cinco apresentações e discussões em grupos. Os grupos de trabalho discutiram os seguintes temas: implementação de uma linha de cuidado em asma; recursos humanos necessários para os PCAA; recursos necessários para financiar os PCAA; e manutenção do funcionamento dos PCAAs. Resultados: A oficina envolveu 39 participantes de todas as regiões do país, representando associações de asmáticos (n = 3), centros universitários (n = 7) e PCAAs (n = 29). Evidenciou-se uma relação direta entre a ausência de planejamento e o insucesso dos PCAAs. Com base nas experiências brasileiras elencadas durante a oficina, as premissas comuns foram a importância da sensibilização do gestor, maior participação da comunidade, interdependência entre a atenção primária e a especializada, observação da regionalização e utilização dos medicamentos disponíveis no sistema público de saúde. Conclusões: O Brasil já tem um núcleo de experiências na área programática da asma. A implementação de uma linha de cuidado em doenças respiratórias crônicas e sua inclusão nas redes de saúde parecem ser o caminho natural. Porém, a experiência nessa área ainda é pequena. Agregar pessoas com experiência nos PCAAs na elaboração da linha de cuidado em asma encurtaria tempo na criação de redes de atenção com possível efeito multiplicador, evitando que se partisse do zero em cada local isolado.

Objective: To report the results of a workshop regarding asthma management programs and centers (AMPCs) in Brazil, so that they can be used as a tool for the improvement and advancement of current and future AMPCs. Methods: The workshop consisted of five presentations and the corresponding group discussions. The working groups discussed the following themes: implementation of asthma management strategies; human resources needed for AMPCs; financial resources needed for AMPCs; and operational maintenance of AMPCs. Results: The workshop involved 39 participants, from all regions of the country, representing associations of asthma patients (n = 3), universities (n = 7), and AMPCs (n = 29). We found a direct relationship between a lack of planning and the failure of AMPCs. Based on the experiences reported during the workshop, the common assumptions about AMPCs in Brazil were the importance of raising awareness of managers; greater community participation; interdependence between primary care and specialized care; awareness of regionalization; and use of medications available in the public health system. Conclusions: Brazil already has a core of experience in the area of asthma management programs. The implementation of strategies for the management of chronic respiratory disease and their incorporation into health care system protocols would seem to be a natural progression. However, there is minimal experience in this area. Joint efforts by individuals with expertise in AMPCs could promote the implementation of asthma management strategies, thus speeding the creation of treatment networks, which might have a multiplier effect, precluding the need for isolated centers to start from zero.
