Abstract: In this study, we evaluated the knowledge, attitudes, and psychosocial impacts among Brazilian pediatric dentists during the COVID-19 pandemic. A cross-sectional study with primary data collection was carried out using an online structured questionnaire. Data were submitted to descriptive analysis by using absolute and relative frequencies. A chi-square test was used for association analysis and log-linear regression models to estimate the prevalence ratio (5%). The population comprised mostly women and knowledge regarding COVID-19 was satisfactory (above 80% in most items). N95 masks and faceshields were used, albeit 64.22% reported difficulty in providing dental care to children due to the need for extra Personal Protective Equipment. Thirty eight percent provided urgency/emergency dental care, 59.78% performed invasive procedures, 59.56% used high speed handpieces, 8.44% started using cariostatics, and 6.22% introduced the use of chemomechanical caries removal agents. Fear for the future (PR = 1.21) and use of medications (for anxiety, depression, or insomnia) increased (PR = 1.16) among the ones who had wage losses. Brazilian pediatric dentists have knowledge about COVID-19, and attitudes in their clinical routines changed due the pandemic. Financial life was harmed and a negative impact of the pandemic in psychosocial aspects of workers was found.

SUMMARY: The rabbit is considered an ideal animal model for studies that describe abnormalities in the testicles due to the similar morphogenetic mechanisms of sexual development and diseases commonly found in humans. The aim of this study was to determine the male sexual differentiation of the New Zealand rabbit (Oryctolagus cuniculus) through development. The gestational age was estimated and classified as 9, 12, 14, 16, 18, 20, 23 and 28 gestational days. The morphological and sexual determination were performed by histological analysis of the reproductive tract in the embryos and fetuses (9-28 days) as well as by immunohistochemistry- Desert hedgehog-Dhh- (testis-specific protein on Y chromosome- 16, 20, 23 days and adult rabbits). Gonads were observed from the 14th day in an undifferentiated stage and with homogeneous aspect. Sexual differentiation was observed from the 16th day with presence of cells forming gonadal cords and Dhh+ cells in the gonadal parenchyma. From the 18th gestational day testicular cords were observed, which evolved into organized seminiferous tubules. The formation of the efferent ducts and ductus deferens and epididymis was observed on the 20th and 23rd days, respectively. The differentiation of the external genitalia occurred from the 23rd days from the anogenital distance and was identified to identify the penile structures. In summary, the features of the sexual differentiation were determined by observation of the Dhh+ protein in embryos from the 16th day to adulthood, and the morphological particularities observed from the 18th gestational day, determined by differentiation of the external genitalia from the 23rd day.

RESUMEN: El conejo se considera un modelo animal ideal para estudios que describen anomalías a nivel testícular debido a que presenta mecanismos morfogenéticos similares al desa- rrollo sexual y enfermedades que se encuentran comúnmente en los seres humanos. El objetivo de este estudio fue determinar la diferenciación sexual masculina del conejo de Nueva Zelanda (Oryctolagus cuniculus) a través del desarrollo. La edad gestacional se estimó y clasificó en 9, 12, 14, 16, 18, 20, 23 y 28 días gestacionales. La determinación morfológica y sexual se realizó mediante análisis histológico del tracto reproductivo en los embriones y fetos (9 - 28 días) así como mediante inmunohistoquímica -Desert hedgehog-Dhh- (proteína testicular específica en el cromosoma Y- 16, 20, 23 días y conejos adultos). Las gónadas se observaron a partir del día 14 en un estadio indiferenciado y con aspecto homogéneo. Se observó diferenciación sexual a partir del día 16 con presencia de células formadoras de cordones gonadales y células Dhh+ en el parénquima gonadal. A partir del día 18 de gestación se observaron cordones testiculares, que evolucionaron a túbulos seminíferos organizados. La formación de los conductos eferentes, deferentes y del epidídimo se observó a los 20 y 23 días, respectivamente. La diferenciación de los genitales externos ocurrió a partir del día 23 desde la distancia anogenital y se utilizó para identificar las estructuras del pene. En conclusión, las características de la diferenciación sexual se determinaron mediante la observación de la proteína Dhh en embriones desde el día 16 hasta la edad adulta, y las particularidades morfológicas observadas a partir del día 18 de gestación, determinadas por diferenciación de los genitales externos a partir del día 23.

Abstract Background Takotsubo syndrome (TTS) is an acquired form of cardiomyopathy. National Brazilian data on this condition are scarce. The Takotsubo Multicenter Registry (REMUTA) is the first to include multicenter data on this condition in Brazil. Objective To describe the clinical characteristics, prognosis, in-hospital treatment, in-hospital mortality, and mortality during 1 year of follow-up. Methods This is an observational, retrospective registry study including patients admitted to the hospital with diagnosis of TTS and patients admitted for other reasons who developed this condition. Evaluated outcomes included triggering factor, analysis of exams, use of medications, complications, in-hospital mortality, and mortality during 1 year of follow-up. A significance level of 5% was adopted. Results The registry included 169 patients from 12 centers in the state of Rio de Janeiro, Brazil. Mean age was 70.9 ± 14.1 years, and 90.5% of patients were female; 63% of cases were primary TTS, and 37% were secondary. Troponin I was positive in 92.5% of patients, and median BNP was 395 (176.5; 1725). ST-segment elevation was present in 28% of patients. Median left ventricular ejection fraction was 40 (35; 48)%. We observed invasive mechanical ventilation in 25.7% of cases and shock in 17.4%. Mechanical circulatory support was used in 7.7%. In-hospital mortality was 10.6%, and mortality at 1 year of follow-up was 16.5%. Secondary TTS and cardiogenic shock were independent predictors of mortality. Conclusion The results of the REMUTA show that TTS is not a benign pathology, as was once thought, especially regarding the secondary TTS group, which has a high rate of complications and mortality.

Resumo Fundamento A síndrome de takotsubo (takotsubo) é uma forma de cardiomiopatia adquirida. Dados nacionais sobre essa condição são escassos. O Registro REMUTA é o primeiro a incluir dados multicêntricos dessa condição no nosso país. Objetivo Descrever as características clínicas, prognóstico, tratamento intra-hospitalar e mortalidade hospitalar e em 1 ano de seguimento. Métodos Estudo observacional, retrospectivo, tipo registro. Incluídos pacientes internados com diagnóstico de takotsubo ou que desenvolveram esta condição durante internação por outra causa. Os desfechos avaliados incluíram fator desencadeador, análise dos exames, uso de medicações, complicações e óbito intra-hospitalar e em 1 ano de seguimento. O nível de significância adotado foi de 5%. Resultados Foram incluídos 169 pacientes, em 12 centros no Estado do Rio de Janeiro. A idade média foi de 70,9 ± 14,1 anos e 90,5% eram do sexo feminino; 63% dos casos foram de takotsubo primário e 37% secundário. Troponina I foi positiva em 92,5% dos pacientes e a mediana de BNP foi de 395 (176,5; 1725). Supradesnivelamento do segmento ST esteve presente em 28% dos pacientes. A fração de ejeção do ventrículo esquerdo teve mediana de 40 (35; 48)%. Observamos taxa de 25,7% de ventilação mecânica invasiva e 17,4% de choque. Suporte circulatório mecânico foi utilizado em 7,7%. A mortalidade intra-hospitalar foi de 10,6% e a mortalidade ao final de 1 ano foi de 16,5%. Takotsubo secundário e choque cardiogênico foram preditores independentes de mortalidade. Conclusão Os resultados do REMUTA mostram que takotsubo não se trata de patologia benigna como se pensava, especialmente no grupo de takotsubo secundário que acarreta elevada taxa de complicações e de mortalidade.

Abstract: En

Objective: To evaluate the best strategy for pacifier disinfection methods. Material and Methods: The literature search was conducted on MEDLINE/PubMed, Scielo, Lilacs, Web of Science, and Scopus databases to find all relevant articles published over the past 20 years, based on PRISMA guidelines. Two reviewers extracted data independently by using a standardized form. The following factors were recorded: country of study, type of study, pacifier material, sample number, microorganisms analyzed, decontamination methods used, method accessibility and results found. Results: A total of 121 articles were obtained from all databases. The selected documents underwent a final screening, resulting in 8 articles. The method of disinfection analyzed by the literature were: 3.5% neutral detergent, apple cider vinegar 70% spray, boiling water during 15 minutes, sodium hypochlorite 2.5, hydrogen peroxide 70% spray, chlorhexidine 0.12%, Brushtox®, sterile water and microwave. Conclusion: Because of the broad methods for pacifier disinfection and different levels of accessibility to disinfectant agents, the pacifier consensus for decontamination remains unclear. Although the disinfection methods are diverse, the methods suggested to its disinfection were identified and described in this article.

ABSTRACT Objective We aimed to identify the frequency of monogenic diabetes, which is poorly studied in multiethnic populations, due to GCK or HNF1A mutations in patients with suggestive clinical characteristics from the Brazilian population, as well as investigate if the MODY probability calculator (MPC) could help patients with their selection. Subjects and methods Inclusion criteria were patients with DM diagnosed before 35 years; body mass index < 30 kg/m2; negative autoantibodies; and family history of DM in two or more generations. We sequenced HNF1A in 27 patients and GCK in seven subjects with asymptomatic mild fasting hyperglycemia. In addition, we calculated MODY probability with MPC. Results We identified 11 mutations in 34 patients (32.3%). We found three novel mutations. In the GCK group, six cases had mutations (85.7%), and their MODY probability on MPC was higher than 50%. In the HNF1A group, five of 27 individuals had mutations (18.5%). The MPC was higher than 75% in 11 subjects (including all five cases with HNF1A mutations). Conclusion Approximately one third of the studied patients have GCK or HNF1A mutations. Inclusion criteria included efficiency in detecting patients with GCK mutations but not for HNF1A mutations (< 20%). MPC was helpful in narrowing the number of candidates for HNF1A screening.

Abstract Objective Monitor the use of chlorhexidine gel dressing in the central venous catheter of children and adults submitted to hematopoietic stem cell transplantation (HSCT) to check for catheter-related bloodstream infection and skin irritation while using this dressing. Methods This is a prospective observational study with 25 patients with central venous catheters (CVC) inserted for hematopoietic stem cell transplantation. Dressing characteristics, skin characteristics, clinical conditions of patients and infection-related characteristics were evaluated daily. Patients were monitored from the first day of CVC insertion until removal, up to 45 days from the CVC insertion date. Results Catheter-related bloodstream infection (CRBSI) occurred in 28% of all patients, with an association between febrile neutropenia and infection (p<0.01). Skin irritation was identified in 24% of patients. No association was found between catheter-related bloodstream infection and skin irritation (p=0.51). A significant association was observed between skin irritation and dressing removal (p=0.03). Unscheduled dressing changes corresponded to 50% of all dressing changes identified during the study, and the main reason was presence of blood in the dressing (57.8%). Conclusion Using chlorhexidine gel dressing in patients submitted to HSCT proved to be an effective measure to reduce the occurrence of catheter-related infections, when compared to literature data. The cases of CRBSI found in this study were mainly associated with the condition of neutropenia, which is very common in this population. The cases of dressing-related skin irritation and presence of blood as the main reason for unscheduled change highlight the importance of nurses having proper knowledge about how to use this dressing in order to create protocols for safe dressing use and handling.

Resumen Objetivo Hacer un seguimiento del uso del vendaje gel de clorhexidina en catéter venoso central (CVC) en niños y adultos sometidos al trasplante de células madre hematopoyéticas (TCMH) para verificar los casos de infección del flujo sanguíneo relacionados con el catéter (IFSRC) y la irritación cutánea durante la validez de este vendaje. Métodos Estudio observacional y prospectivo, con 25 pacientes con catéter venoso central insertado para realizar el trasplante de células madre hematopoyéticas. Diariamente se evaluaron las características del vendaje y de la piel, las características clínicas del paciente y las relacionadas con la infección. Los pacientes recibieron un seguimiento a partir del primer día de la inserción del CVC hasta su retirada, con un límite de 45 días a partir de la fecha de inserción del CVC. Resultados La infección del flujo sanguíneo relacionada con el catéter se presentó en el 28% de los pacientes, hubo relación entre neutropenia febril e infección (p<0,01). Se identificó irritación cutánea en el 24% de los pacientes. No se identificó relación entre la infección del flujo sanguíneo relacionada con el catéter y la irritación cutánea (p=0,51). Hubo relación significativa entre la irritación cutánea y la suspensión del uso del vendaje (p=0,03). Los cambios no programados sucedieron en el 50% de los cambios registrados, y el motivo principal fue la presencia de sangre en el vendaje (57,8%). Conclusión El uso del vendaje gel de clorhexidina en pacientes sometidos al TCMH demostró ser una medida eficaz para la reducción de casos de infecciones relacionadas con el catéter, en comparación con los datos de la literatura. Los casos de IFSRC encontrados se relacionaron principalmente con la condición de neutropenia, muy común en esta población. Los casos identificados de irritación cutánea relacionados con el vendaje y la presencia de sangre como principal motivo de cambio no programado resaltan la importancia del conocimiento del uso del vendaje por parte de los enfermeros asistenciales, a fin de crear protocolos que indiquen el uso y manejo seguro del vendaje.

BACKGROUND The heat-labile nature of Dengue virus (DENV) in serum samples must be considered when applying routine diagnostic tests to avoid issues that could impact the accuracy of test results with direct implications for case management and disease reporting. OBJECTIVES To check if pre-analytical variables, such as storage time and temperature, have an impact on the accuracy of the main routine diagnostic tests for dengue. METHODS Virus isolation, reverse transcription real-time polymerase chain reaction (RT-PCR) and NS1 enzyme-linked immunosorbent assay (ELISA) were evaluated using 84 samples submitted to different pre-analytical conditions. FINDINGS Sensitivity and negative predictive value were directly affected by sample storage conditions. RT-PCR and virus isolation showed greater dependence on well-conserved samples for an accurate diagnosis. Interestingly, even storage at -30ºC for a relatively short time (15 days) was not adequate for accurate results using virus isolation and RT-PCR tests. On the other hand, NS1 ELISA showed no significant reduction in positivity for aliquots tested under the same conditions as in the previous tests. MAIN CONCLUSIONS Our results support the stability of the NS1 marker in ELISA diagnosis and indicate that the accuracy of routine tests such as virus isolation and RT-PCR is significantly affected by inadequate transport and storage conditions of serum samples.

SUMMARY: Due to the very important role in Brazilian ecosystems, studying the anatomy of opossums is extremely relevant for their natural preservation and possible clinical and surgical interventions with captive animals. These marsupials occupy diversified niches being well distributed throughout the Brazilian territory. They collaborate in the control of urban and agricultural pests such as rodents and insects. They are also excellent dispersers of seeds through their feces. The conclusion is that opossums can be a great model for the study of the anatomy of wild animals.

RESUMEN: Las zarigüeyas desempeñan un papel muy relevante en los ecosistemas brasileños, siendo extremadamente importante estudiar su anatomía para su preservación natural y posibles intervenciones clínicas y quirúrgicas de los animales en cautiverio. Estos marsupiales ocupan nichos diversificados y están bien distribuidos en todo el territorio brasileño. Colaboran en el control de plagas urbanas y agrícolas, como roedores e insectos. También son excelentes dispersores de semillas a través de sus heces. Por lo tanto, se concluye que las zarigüeyas pueden ser un gran modelo para estudiar la anatomía de los animales salvajes.

SUMMARY: Natural anatomical pieces of wild animals are rare and teachers seek alternatives in satisfactory quantity and quality to inform their students. This article aims to describe the use of multiplanar reconstructions and 3D volume rendering computed tomography (CT) images, rapid prototyping and 3D printing of opossum head to create a biomodel to veterinary education in descriptive anatomy of wild animals. A six-step method study was conducted to construct the biomodel: (1) selection of opossum head from museum; (2) CT scanning of bones structures in veterinary hospital; (3) DICOM visualization medical images in multiplanar reconstructions and 3D volume rendering; (4) .dicom file conversion to .stl; (5) 3D printing of opossum head by rapid prototyping; (6) comparison of 3D model printed with the original anatomical piece. The use of CT images with their different forms of reconstruction can provide a more comprehensive 3D view of opossum craniofacial region and allow a better understanding of head anatomy of this species. The 3D printed biomodel can be a viable alternative to original bone specimens when used in anatomy education. However, further studies must be continued to validate the method in Veterinary Medicine courses.

RESUMEN: Las piezas anatómicas naturales de animales salvajes son raras y los profesores buscan alternativas satisfactorias, en cantidad y calidad, para enseñar a sus alumnos. Este artículo tuvo como objetivo describir el uso de la reconstrucción volumétrica por tomografía computarizada, la creación rápida de prototipos y la impresión 3D de la cabeza de zarigüeya para obtener un biomodelo en anatomía descriptiva de animales salvajes para educación veterinaria. Se realizó un estudio en seis pasos para construir el biomodelo: (1) selección de cabeza de zarigüeya del museo; (2) tomografía computarizada de estructuras óseas en hospital veterinario; (3) visualización de las imágenes médicas en DICOM por reconstrucciones multiplanares y renderización de volumen 3D; (4) conversión de archivos .dicom a .stl; (5) impresión 3D de cabeza de zarigüeya mediante prototipado rápido; (6) comparación del modelo 3D impreso con la pieza anatómica original. El uso de imágenes de tomografía computarizada, con sus diferentes formas de reconstrucción, puede proporcionar una vista 3D más completa de la región craneofacial de zarigüeya y permitir una mejor comprensión de la anatomía de la cabeza de esta especie. El biomodelo 3D impreso puede ser una alternativa viable a las muestras óseas originales cuando se utiliza en la educación de la anatomía. Sin embargo, se deben continuar los estudios para validar el método en los cursos de Medicina Veterinaria.

Resumo Este artigo busca discutir a evolução das desigualdades em saúde e no acesso aos serviços de saúde nas grandes regiões a partir de inquéritos domiciliares realizados de 1998 a 2013. As desigualdades sociais foram analisadas pelas razões de extremos de anos de escolaridade, considerando duas faixas etárias (18 a 59 anos e 60 anos ou mais). Nas condições de saúde, observa-se, nos dois grupos etários, uma pior avaliação do estado de saúde e um aumento da prevalência de diabetes e hipertensão, o que pode estar relacionado à expansão da atenção básica. Quanto à realização de consultas médicas no último ano, encontra-se, no geral, maior acesso, com manutenção de pequenas desigualdades. A maior utilização de consulta odontológica entre os de menor escolaridade provoca uma redução nas desigualdades, que ainda são significativas. As internações hospitalares, ao longo da série, são maiores entre os menos escolarizados, e há uma redução nas taxas nos dois grupos etários, em quase todas as regiões. Percebe-se um aumento na realização de mamografia por mulheres menos escolarizadas, com diminuição da desigualdade. Os resultados corroboram a necessidade da continuidade dos inquéritos domiciliares para o monitoramento das desigualdades regionais e sociais no acesso ao sistema de saúde.

Abstract This article discusses trends in health inequalities and access to health services across the regions of Brazil using data from household surveys conducted between 1998 and 2013. Social inequality was measured based on the ratio between the extremes of years of schooling considering two age groups (18 to 59 years and 60 years and over). The findings show a decline in health status and increase in prevalence of diabetes and hypertension in both age groups, which may be related to the expansion of primary healthcare. The findings regarding the percentage of people who had had a medical appointment in the last 12 months show that low levels of inequalities persist despite a general improvement in access. Despite an increase in the percentage of people with up to 3 years of schooling who had had a dental appointment in the last year, significant inequalities persist. The percentage of people who reported being admitted to hospital in the last 12 months was greater among people with up to 3 years of schooling throughout the study period. The hospitalization rate decreased in both age groups across almost all regions. The proportion of women aged between 50 and 69 years with up to 3 years of schooling who had had a mammogram increased, leading to a decrease in inequality. The findings show the need to ensure the continuity of household surveys to monitor inequalities in access to health care services by region and social group.

ABSTRACT This study aimed to longitudinally evaluate the functional performance of infants affected by Congenital Zika Syndrome (CZS). A study was carried out with infants from the Laboratório de Estudos em Pediatria of the Universidade Federal de Pernambuco and the Aliança de Mães e Famílias Raras, aged between 6 and 24 months, of both genders. The Pediatric Evaluation of Disability Inventory (PEDI) was applied to analyze functional performance in two evaluations, with a minimum of six months interval between them. Data analysis was performed using the Wilcoxon test. In the sample of 16 infants, we observed a change in the classification from normal to delay in the domains of self-care and social function, with a significant decrease in normative scores (p=0.001 and p<0.001, respectively); in the mobility, individuals initially classified with delay also presented reduction of normative scores (p=0.001), remaining in the same classification. Despite the significant increase in gross self-care scores (p=0.024) and mobility (p=0.001), infants remained classified as delayed. Caregiver care was analyzed in these evaluation, in which 100% of infants were delayed in all three domains of the PEDI, receiving maximum or full care. The main environmental modifications were those focused on the child. We concluded that infants with CZS presented significant delays in functional performance, with a slow evolution in the evaluated range.

RESUMEN El objetivo del estudio fue evaluar longitudinalmente el desempeño funcional de lactantes con síndrome congénito del zika (SCZ). Se realizó un estudio con lactantes de entre 6 y 24 meses, de ambos los sexos, identificados por el Laboratorio de Estudios en Pediatría de la Universidad Federal de Pernambuco y por la Aliança de Mães e Famílias Raras (Alianza de Madres y Familias Raras). Se aplicó el Inventario de Evaluación Pediátrica de Discapacidad (PEDI) para análisis del desempeño funcional en dos evaluaciones, con al menos seis meses de intervalo. El análisis de los datos fue realizado por la prueba de Wilcoxon. En la muestra de 16 lactantes se observó cambio en los campos de autocuidado y función social, de “normal” para “retraso”, con disminución significativa de los puntajes normativos (p=0,001 y p<0,001, respectivamente). En la movilidad, los lactantes inicialmente clasificados con retraso también presentaron reducción de los puntajes normativos (p=0,001), manteniéndose en la clasificación. A pesar del aumento significativo en los puntajes netos del autocuidado (p=0,024) y movilidad (p=0,001), los lactantes continuaron clasificados en retraso. En la asistencia del cuidador, un 100% de los lactantes se encontraban en retraso en los tres dominios del PEDI, recibiendo asistencia máxima o total. Las principales modificaciones ambientales encontradas fueron las centradas en el niño. En resumen, los lactantes con SCZ presentaron retrasos significativos en el desempeño funcional, con una evolución lenta en el intervalo de tiempo evaluado.

RESUMO O objetivo do estudo foi avaliar longitudinalmente o desempenho funcional de lactentes acometidos pela síndrome congênita do zika (SCZ). Realizou-se um estudo com lactentes provenientes do Laboratório de Estudos em Pediatria da Universidade Federal de Pernambuco e da Aliança de Mães e Famílias Raras, com idade entre 6 e 24 meses, de ambos os sexos. O Inventário de Avaliação Pediátrica de Incapacidade (PEDI) foi aplicado para análise do desempenho funcional em duas avaliações, com no mínimo seis meses de intervalo. A análise dos dados foi realizada pelo teste de Wilcoxon. Na amostra de 16 lactentes, observou-se que entre as avaliações houve mudança na classificação de normal para atraso nos domínios de autocuidado e função social, com diminuição significativa dos escores normativos (p=0,001 e p<0,001, respectivamente); na mobilidade, os lactentes inicialmente classificados com atraso também apresentaram redução dos escores normativos (p=0,001), mantendo-se na classificação. Apesar do aumento significativo nos escores brutos do autocuidado (p=0,024) e mobilidade (p=0,001), os lactentes continuaram classificados em atraso. Na assistência do cuidador, 100% dos lactentes se encontraram em atraso nos três domínios do PEDI, recebendo assistência máxima ou total. As principais modificações ambientais encontradas foram as centradas na criança. Em suma, os lactentes com SCZ deste estudo apresentaram atrasos significativos no desempenho funcional, com uma evolução lenta no intervalo de tempo avaliado.

Abstract: En | Text: En | PDF: En

A total of 124 Neisseria gonorrhoeae isolates recovered during a 12-year period (2003-2015) from outpatients assisted at Centro de Referência e Treinamento DST/AIDS-CRT of São Paulo city, Brazil, were analysed. The following resistance rates were observed: penicillin-59.6%, ciprofloxacin-15.3%, and azithromycin-6.7%. Although reduced susceptibility to these drugs was observed since 2003, no ceftriaxone-resistant isolates were detected. Ciprofloxacin- and azithromycin non-susceptible isolates were grouped in 11 clusters. Mutations were detected in GyrA and ParC of isolates 124 and 260, and a C2611T substitution on 23S rRNA alleles was also observed in isolate 260. Both isolates belonged to ST1901/ST6210 (MSLT/NG-MAST schemes).
