Can habits and behaviors predict colonization by community-associated MRSA in patients admitted to a Brazilian hospital?

This study aimed to identify factors associated with colonization by community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in adult patients admitted to a Brazilian hospital. This is a cross-sectional study, in which patients underwent a nasal swab and were asked about hygiene behavior, habits, and clinical history. Among the 702 patients, 180 (25.6%) had S. aureus and 21 (2.9%) MRSA. The factors associated with MRSA colonization were attending a gym (OR 4.71; 95% CI; 1.42 - 15.06), smoking habit in the last year (OR 2.37; 95% CI; 0.88 - 6.38), previous hospitalization (OR 2.18; CI 95%; 0.89 - 5.25), and shared personal hygiene items (OR 1.99; 95% CI; 0.71 - 5.55). At the time of admission, colonization by CA-MRSA isolates was higher than that found in the general population. This can be an important public health problem, already endemic in hospitals, whose factors such as those associated with habits (smoking cigarettes) and behaviors (team sports practice and activities in gyms) have been strongly highlighted. These findings may help developing infection control policies, allowing targeting patients on higher-risk populations for MRSA colonization.

Methicillin-resistant Staphylococcus aureus and coagulase-negative Staphylococcus produce antimicrobial substances against members of the skin microbiota in children with atopic dermatitis.

Coagulase-negative Staphylococcus (CoNS) species inhibiting Staphylococcus aureus has been described in the skin of atopic dermatitis (AD) patients. This study evaluated whether Staphylococcus spp. from the skin and nares of AD and non-AD children produced antimicrobial substances (AMS). AMS production was screened by an overlay method and tested against NaOH, proteases and 30 indicator strains. Clonality was assessed by pulsed-field gel electrophoresis. Proteinaceous AMS-producers were investigated for autoimmunity by the overlay method and presence of bacteriocin genes by polymerase chain reaction. Two AMS-producers had their genome screened for AMS genes. A methicillin-resistant S. aureus (MRSA) produced proteinaceous AMS that inhibited 51.7% of the staphylococcal indicator strains, and it was active against 60% of the colonies selected from the AD child where it was isolated. On the other hand, 57 (8.8%) CoNS from the nares and skin of AD and non-AD children, most of them S. epidermidis (45.6%), reduced the growth of S. aureus and other CoNS species. Bacteriocin-related genes were detected in the genomes of AMS-producers. AMS production by CoNS inhibited S. aureus and other skin microbiota species from children with AD. Furthermore, an MRSA colonizing a child with AD produced AMS, reinforcing its contribution to dysbiosis and disease severity.

Atopic dermatitis pediatric patients show high rates of nasal and intestinal colonization by methicillin-resistant Staphylococcus aureus and coagulase-negative staphylococci.

BACKGROUND: Atopic dermatitis (AD) patients have high rates of colonization by Staphylococcus aureus, which has been associated with worsening of the disease. This study characterized Staphylococcus spp isolates recovered from nares and feces of pediatric patients with AD in relation to antimicrobial susceptibility, staphylococcal cassette chromosome mec (SCCmec) type, presence of pvl genes and clonality. Besides, gut bacterial community profiles were compared with those of children without AD. RESULTS: All 55 AD patients evaluated had colonization by Staphylococcus spp. Fifty-three (96.4%) patients had colonization in both clinical sites, whereas one patient each was not colonize in the nares or gut. Staphylococcus aureus was identified in the nostrils and feces of 45 (81.8%) and 39 (70.9%) patients, respectively. Methicillin-resistant Staphylococcus spp. isolates were found in 70.9% of the patients, and 24 (43.6%) had methicillin-resistant S. aureus (MRSA). S. aureus (55.6%) and S. epidermidis (26.5%) were the major species found. The prevalent lineages of S. aureus were USA800/SCCmecIV (47.6%) and USA1100/SCCmecIV (21.4%), and 61.9% of the evaluated patients had the same genotype in both sites. Additionally, gut bacterial profile of AD patients exhibits greater dissimilarity from the control group than it does among varying severities of AD. CONCLUSIONS: High rates of nasal and intestinal colonization by S. aureus and methicillin-resistant staphylococci isolates were found in AD patients. Besides, gut bacterial profiles of AD patients were distinctly different from those of the control group, emphasizing the importance of monitoring S. aureus colonization and gut microbiome composition in AD patients.

Non­synonymous polymorphisms in the HRC and ADRB1 genes may be associated with all­cause death in patients with non­ischemic heart failure.

Sudden cardiac death (SCD) is an unpredictable and common mode of death in patients with heart failure (HF). Alterations in calcium handling may lead to malignant arrhythmias, resulting in SCD, and variants in calcium signaling-related genes have a significant association with SCD. Therefore, the aim of the present retrospective cohort study was to investigate the association of Ser96Ala [histidine-rich calcium-binding protein (HRC)], Ser49Gly [ß1-adrenergic receptor (ADRB1)], Arg389Gly (ADRB1) and Gly1886Ser [ryanodine receptor 2 (RYR2)] polymorphisms with serious arrhythmic events and overall mortality in patients with HF with reduced left ventricular ejection fraction of non-ischemic etiology. In total, 136 patients with HF underwent physical examination, routine laboratory tests, non-invasive assessment of cardiac function and an invasive electrophysiological study. The primary outcome was the occurrence of serious arrhythmic events, set as either SCD or appropriate implantable cardioverter-defibrillator (ICD) therapy, and the secondary outcome was all-cause death. During a median follow-up of 37 months, arrhythmic events occurred in 26 patients (19%) and 41 patients (30%) died. Patients carrying the Ser allele of the Ser96Ala polymorphism in HRC had worse survival than those with the Ala/Ala genotype (log-rank P=0.043). Despite the difference in survival time, the Ala/Ala genotype was not associated with all-cause death in the regression analysis [unadjusted hazard ratio (HR)=0.17; 95% CI, 0.02-1.21]. Regarding the Ser49Gly and Arg389Gly polymorphisms in ADRB1, homozygosity for the major alleles at both sites (Ser49Ser and Arg389Arg) was associated with a two-fold increased risk of all-cause death compared with the other genotype combinations (unadjusted HR=1.98; 95% CI, 1.02-3.82). However, this association was lost after controlling for clinical covariates. No association was observed for the Gly1886Ser polymorphism in RYR2. Overall, the present findings are concurrent with the hypothesis that the Ser96Ala (HRC), Ser49Gly (ADRB1) and Arg389Gly (ADRB1) polymorphisms may be associated with HF prognosis. In particular, the Ser96Ala polymorphism might aid in risk stratification and patient selection for ICD implantation.

A experiência da escrita para uma construção cartográfica: caderno digital itinerante como dispositivo / The writing experience for a cartographic construction: itinerant digital notebook as a device / La experiencia de escritura para una construcción cartográfica: el cuaderno digital itinerante como dispositivo

O objetivo deste trabalho foi discutir acerca da utilização de um dispositivo de pesquisa: o caderno digital itinerante, a partir do qual foi possível promover a construção conjunta de uma pesquisa, partindo do método cartográfico. A pesquisa de campo que deu origem a esta reflexão metodológica teve por objetivo principal cartografar experiências sapatão na cidade, por meio da construção conjunta de um caderno digital itinerante no qual as participantes, juntamente com a pesquisadora, escreviam sobre suas experiências como mulheres lésbicas e/ou pessoas que se reconheciam enquanto sapatão. Tendo como um dos instrumentos a análise do diário de campo, produzido durante a pesquisa, foi possível discutir em profundidade o enfoque metodológico adotado e questionar a dicotomia pesquisadora-objeto, provocando algumas reflexões acerca da temática da participação e do desenvolvimento de pesquisas on-line, sobretudo no período pandêmico. Por fim, apostar na cartografia enquanto método de pesquisa com e não sobre permitiu a produção de uma pesquisadora sapatão que pudesse se ocupar da escuta, lendo sobre diferentes processos de subjetivação e, com isso, produzindo outros sentidos para seu objeto de pesquisa.

The aim of this study was to discuss the use of a research tool: the itinerant digital notebook, which facilitated the collaborative construction of research based on the cartographic method. The field research that gave rise to this methodological reflection aimed to map dyke experiences in the city through the collaborative construction of an itinerant digital notebook. In this note-book, participants, alongside the researcher, wrote about their experiences as lesbian women and/or individuals who identified as dykes. Using the analysis of the field diary produced during the research as one of the instruments, it was possible to deeply discuss the adopted methodological approach and question the researcher-object dichotomy, prompting reflections on the theme of participation and the development of online research, especially during the pandemic period. Ultimately, embracing cartography as a research method with, not on, participants allowed the production of a dyke researcher who could engage in listening, reading about different processes of subjectivation, and thereby generating alternative meanings for her object of study.

Síndrome de Burnout en estudiantes y profesionales de la Carrera de Terapia Ocupacional de la Universidad Central del Ecuador / Burnout syndrome in students and professionals of the Occupational Therapy Career of the Central University of Ecuador

Introducción: El síndrome de Burnout es un fenómeno muy común en los diferentes am-bientes de trabajo, pero estudios de prevalencia en profesionales y estudiantes de terapia ocupacional son limitados.Objetivo: Establecer la presencia de síndrome de Burnout en estudiantes y profesionales de los centros de práctica de la carrera de Terapia Ocupacional de la Universidad Central del Ecuador.Material y métodos: Diseño de estudio observacional, descriptivo, de corte transversal, en 177 estudiantes de la carrera de Terapia Ocupacional y 35 profesionales en el área que laboran en los centros de práctica vinculados a la práctica preprofesional. En cada suje-to se determinó agotamiento emocional, despersonalización y falta de realización personal mediante la Escala Maslach Burnout Inventory; la presencia de nivel alto en las subescalas agotamiento emocional y despersonalización y nivel bajo en realización personal define sín-drome de Burnout. Se calculó la prevalencia del síndrome en estudiantes y profesionales y la correlación con años de ejercicio laboral y sexo.Resultados: El 2.9 % (1/35) de los profesionales y 4.5 % (8/177) de estudiantes presentaron síndrome Burnout, el que se relacionó con las variables ambientales personales incluidas en la escala de Maslach. Del 45.83% al 82.14 % de estudiantes presentaron niveles bajos de cansancio emocional y despersonalización, mientras que, del 37.14 % al 52.94 %, presenta-ron niveles medios de realización personal.Conclusión: La prevalencia del síndrome de Burnout es baja en los profesionales y en los estudiantes de la carrera de Terapia Ocupacional que hacen prácticas preprofesionales en diferentes instituciones.

Introduction: Burnout syndrome is a very common phenomenon in different work environments; however, prevalence studies in occupational therapy professionals and students are limited.Objective: To establish the presence of Burnout syndrome in students and professionals at practice centers of the Occupational Therapy Career from Universidad Central del Ecuador.Material and methods: Cross-sectional, descriptive, observational study design in 177 stu-dents belonging to the Occupational Therapy Career and 35 professionals in the area who work in the practice centers linked to pre-professional practice. Emotional exhaustion, de-personalization and lack of personal fulfillment were determined in each subject using the Maslach Burnout Inventory Scale; the presence of a high level in the emotional exhaustion and depersonalization subscales and a low level of personal fulfillment defines Burnout syn-drome. The prevalence of Burnout syndrome in students and professionals and the correla-tion with years of work practice and gender were calculated.Results: 2.9% (1/35) of the professionals and 4.5% (8/177) of the students presented Bur-nout syndrome, which was related to the personal environmental variables included in the Maslach scale. From 45.83% to 82.14% of students presented low levels of emotional fati-gue and depersonalization; on the other hand, from 37.14% to 52.94% presented average levels of personal fulfillment.Conclusion: The prevalence of Burnout syndrome is low as in professionals as in students of the Occupational Therapy Career who do pre-professional practices in different institutions.

Clinical-epidemiological characterization of women who received post-exposure HIV prophylaxis in a public hospital in Porto Alegre, Rio Grande do Sul / Caracterização clínico-epidemiológica de mulheres que receberam a profilaxia pós-exposição ao HIV em um hospital público de Porto Alegre, Rio Grande do Sul

Introduction: Prevention strategies are key to combating the epidemic of infections such as HIV and syphilis. The epidemiological scenario of Porto Alegre/RS for these infections shows the need for greater efforts in the area of prevention, seeking to characterize both the population that uses these strategies and the services involved in the care of exposed people. Objective: This study aimed to characterize the clinical and epidemiological profile of patients who received post-exposure prophylaxis (PEP) to HIV treated in a public hospital in Porto Alegre/RS. Methods: This is a retrospective, research, descriptive study based on the Clinical Protocol and Therapeutic Guidelines for PEP, updated in 2018 by the Ministry of Health. Prophylaxis request forms and medical records of patients treated were analyzed. Results: The population consisted of 87 women who received PEP from January to September 2019. There was a predominance of women aged between 20 and 29 years old (55.2%). The most frequent sexual exposure was consensual (69.0%) followed by sexual assault (31.0%). Porto Alegre was the place of residence of most patients (73.6%). The most frequently used therapeutic regimen was the combination of atazanavir, ritonavir, and tenofovir plus lamivudine. On the first visit, 8.0% of the patients showed reactive results for the treponemal syphilis test. Only 23.0% and 14.9% of patients returned for anti-HIV tests in the first and third months after exposure, respectively, and the results were non-reactive. Only 19 patients (21.8%) attended the consultations between 0 and 28 days after PEP. Conclusion: It was identified that a considerable percentage of women already had reactive serology for syphilis, most women did not return for follow-up within 28 and 90 days after the first consultation, more than half of the women were aged between 20 and 29 years old, and the most frequent sexual exposure was consensual. In this sense, efforts are needed, such as adequate counseling, adoption of interventions such as sending messages by cell phone, telephone calls, and preparation of educational materials, seeking to improve adherence to treatment and follow-up in the service, which is important given the scenario of epidemiology in Porto Alegre.Keywords: HIV. Sexually transmitted diseases. Post-exposure prophylaxis. Disease prevention

Introdução: Estratégias de prevenção são fundamentais para o combate à epidemia de infecções como o vírus da imunodeficiência humana (HIV) e sífilis. O cenário epidemiológico de Porto Alegre/RS para essas infecções mostra a necessidade de maiores esforços na área de prevenção, buscando caracterizar tanto a população que utiliza essas estratégias quanto os serviços envolvidos no atendimento das pessoas expostas. Objetivo: Caracterizar o perfil clínico-epidemiológico das pacientes que receberam a profilaxia pós-exposição (PEP) ao HIV atendidas em um hospital público de Porto Alegre/RS. Métodos: Trata-se de um estudo retrospectivo, documental, descritivo e baseado no Protocolo Clínico e Diretrizes Terapêuticas para PEP, atualizado em 2021 pelo Ministério da Saúde. Foram analisados os formulários de solicitação da profilaxia e prontuários das pacientes atendidas. Resultados: A população foi composta de 87 mulheres que receberam a PEP no período de janeiro a setembro de 2019. Predominaram mulheres com idades entre 20 e 29 anos (55,2%). A exposição sexual mais frequente foi a consentida (69,0%), seguida pela violência sexual (31,0%). Porto Alegre foi o local de residência da maioria das pacientes (73,6%). O esquema terapêutico utilizado com maior frequência foi a combinação com atazanavir, ritonavir e tenofovir associado à lamivudina. No primeiro atendimento, 8,0% das pacientes demonstraram resultados reagentes para o teste treponêmico de sífilis. Retornaram para a realização dos testes anti-HIV no primeiro e terceiro mês após a exposição apenas 23,0 e 14,9% das pacientes, respectivamente, e os resultados foram não reagentes. Apenas 19 delas (21,8%) compareceram às consultas entre zero e 28 dias posteriores à PEP. Conclusão: Foi identificado que um percentual considerável de mulheres já apresentava sorologia reagente para sífilis, a maioria das mulheres não retornou para o seguimento no período de 28 e 90 dias após o primeiro atendimento, mais da metade delas tinha idade entre 20 e 29 anos e a exposição sexual mais frequente foi a consentida. Nesse sentido, são necessários esforços como aconselhamento adequado, adoção de intervenções como o envio de mensagens pelo celular, ligações telefônicas e elaboração de materiais educativos, buscando a melhoria da adesão ao tratamento e do acompanhamento no serviço, o que é importante diante do cenário epidemiológico de Porto Alegre.Palavras-chave: HIV.

Systemic infection caused by the methicillin-resistant Staphylococcus aureus USA300-LV lineage in a Brazilian child previously colonized

ABSTRACT The methicillin-resistant Staphylococcus aureus (MRSA) USA300-Latin American variant (USA300-LV) lineage is well documented in northern Latin American countries. It has replaced established clones in hospital environments. We herein report a systemic infection caused by a USA300-LV isolate in a 15-year-old boy, from a low-income area of Rio de Janeiro, previously colonized by the same strain. During hospital stay, seven pvl-positive MRSA USA300-LV isolates were recovered by nasal swab, blood and abscess secretion. The patient underwent intravenous vancomycin, daptomycin, and oral sulfamethoxazole/trimethoprim, and was discharged after 45 days after full recovery. This is the first documented case of a community-acquired MRSA infection caused by the USA300-LV variant in Brazil in a previously colonized adolescent with no history of recent travel outside of Rio de Janeiro. The need for improved surveillance programs to detect MRSA colonization in order to control the spread of hypervirulent lineages among community and hospital settings is highlighted.

Evolução temporal da via de parto e os fatores maternos associados no Brasil (2011-2021) / Temporal evolution of the way of delivery and associated maternal factors in Brazil (2011-2021) / Evolución temporal de la vía del parto y factores maternos asociados en Brasil (2011-2021)

O processo de parto é um evento fisiológico fundamental na vida reprodutiva das mulheres. No entanto, o parto cirúrgico tem se tornado cada vez mais comum, tanto no Brasil como em outros países, resultando em preocupações com a medicalização excessiva do parto. O estudo visa fornecer informações abrangentes sobre o tema, considerando diferentes regiões geográficas do Brasil. Trata-se de estudo é ecológico e retrospectivo, utilizando dados do Sistema de Informações sobre Nascidos Vivos (SINASC) disponíveis no Departamento de Informática do Sistema Único de Saúde (DATASUS). Foram analisados dados de 2011 a 2021, com ênfase nas taxas de parto vaginal e cesariano, fatores sociodemográficos e obstétricos. Durante o período analisado, foram registrados 31.702.562 nascimentos no Brasil. Dos registros válidos, 43,9% foram partos vaginais e 56,1% foram cesarianos. Houve um aumento geral nas taxas de cesariana em todas as regiões brasileiras. A região Norte teve o maior percentual de partos vaginais (53,5%) e o menor de cesarianas (46,5%), enquanto as regiões Sul, Sudeste e Centro-Oeste apresentaram as maiores taxas de cesárea. O estudo revela um aumento nas taxas de cesariana ao longo da última década no Brasil, com diferenças regionais significativas. A prevalência de cesarianas nas regiões Sul, Sudeste e Centro-Oeste levanta preocupações sobre a medicalização do parto. Essas informações podem subsidiar ações de melhoria da qualidade da assistência ao parto e nascimento, com o objetivo de reduzir intervenções desnecessárias e promover melhores desfechos materno-fetais.

The childbirth process is a fundamental physiological event in the reproductive life of women. However, surgical delivery has become increasingly common, both in Brazil and in other countries, resulting in concerns about the excessive medicalization of childbirth. The study aims to provide comprehensive information on the subject, considering different geographic regions of Brazil. This is an ecological and retrospective study, using data from the Information System on Live Births (SINASC) available at the Department of Informatics of the Unified Health System (DATASUS). Data from 2011 to 2021 were analyzed, with emphasis on vaginal and cesarean delivery rates, sociodemographic and obstetric factors. During the analyzed period, 31,702,562 births were registered in Brazil. Of the valid records, 43.9% were vaginal deliveries and 56.1% were cesarean sections. There was a general increase in cesarean section rates in all Brazilian regions. The North region had the highest percentage of vaginal deliveries (53.5%) and the lowest of cesarean sections (46.5%), while the South, Southeast and Midwest regions had the highest cesarean rates. The study reveals an increase in cesarean rates over the last decade in Brazil, with significant regional differences. The prevalence of cesarean sections in the South, Southeast and Midwest regions raises concerns about the medicalization of childbirth. This information can support actions to improve the quality of delivery and birth care, with the aim of reducing unnecessary interventions and promoting better maternal-fetal outcomes.

Implicações da prática profissional no acolhimento institucional de crianças: perspectiva de cuidadoras / Implications of professional practice in children's institutional sheltering: caregivers' perspective / Implicaciones de la práctica profesional en el alojamiento institucional de niños: perspectiva de cuidadoras

Este estudo qualitativo teve como objetivo compreender, a partir da teoria de bioecológica de desenvolvimento, as implicações da prática profissional no processo de acolhimento de crianças em uma casa-abrigo, na perspectiva de cuidadoras. As participantes foram 10 profissionais de uma casa-abrigo localizada na região sul do Brasil. Utilizou-se a entrevista semiestruturada e a organização e análise dos dados sustentou-se na Grounded Theory, com auxílio do software Atlas.ti 8.4.14. Os resultados evidenciaram uma centralização das ações de acolhimento e atenção em torno dos cuidados físicos das crianças. As ações para promover suporte e cuidados emocionais dentro da casa-abrigo eram delegadas às profissionais da equipe técnica da instituição. Observou-se que as dificuldades encontradas pelas cuidadoras diziam respeito à falta de segurança e preparação para responder e acolher as demandas emocionais das crianças, as quais estão presentes em diversos momentos do processo de acolhimento. Percebeu-se que as práticas institucionais afetaram decisivamente tanto as ações de acolhimento das participantes e o suporte emocional oferecido às crianças na passagem pela casa-abrigo quanto as cuidadoras, no sentido de vivenciarem no trabalho sentimentos de insegurança. Os resultados tensionam ecologicamente a interação nos processos proximais presentes no desenvolvimento humano. Advoga-se pela reflexão sobre as implicações das práticas institucionais de uma casa-abrigo e o desenvolvimento infantil, visando o cuidado integral dos acolhidos.(AU)

Based on the developmental bioecological theory, this study analyzes the implications of professional practice in children's user embracement at a shelter from the caregivers' perspective. Semi-structured interviews were conducted with 10 professionals from a shelter located in southern Brazil. Data organization and analysis was performed based on Grounded Theory using the Atlas.ti 8.4.14 software. Results showed that embracement and attention focus on the physical care of children. Support and emotional care activities were delegated to the institution's technical team. Caregivers faced difficulties regarding the lack of security and preparation to respond to and accept the children's emotional demands, which arise at different moments in the embracement process. The institutional practices decisively affected both user embracement actions and the emotional support offered to the children, as well as the caregivers, in the sense of experiencing feelings of insecurity. These findings ecologically tension the interaction in the proximal processes present in human development. Further reflections on the implications of institutional shelter-based practices for child development are needed to provide comprehensive care.(AU)

Este estudio cualitativo tuvo como objetivo comprender, desde la perspectiva de la teoría bioecológica del desarrollo, las implicaciones de la práctica profesional en el proceso de acogida de niños en una institución infantil desde la perspectiva de las cuidadoras. Las participantes fueron 10 profesionales de una institución de acogida infantil ubicada en la región Sur de Brasil. Se utilizó la entrevista semiestructurada, y para la organización y análisis de datos se aplicó Grounded Theory, con el uso del software Atlas.ti 8.4.14. Los resultados mostraron que las acciones de recepción y atención se centran en el cuidado físico de los niños. Las acciones de promoción de apoyo y cuidado emocional dentro del alojamiento se asignaron a los profesionales del equipo técnico de la institución. Se observó que las dificultades encontradas por las cuidadoras estaban relacionadas con la falta de seguridad y preparación para responder y aceptar las demandas emocionales de los niños, las cuales se encuentran presentes en diferentes momentos del proceso de acogida. Se notó que las prácticas institucionales afectaron decisivamente tanto las acciones de acogida de las participantes como el apoyo emocional que la institución brinda a los niños durante su paso, así como a las cuidadoras en el sentido de experimentar sentimientos de inseguridad en el trabajo. Estos resultados tensan ecológicamente la interacción en los procesos proximales presentes en el desarrollo humano. Se aboga por reflexionar sobre las implicaciones de las prácticas institucionales en los alojamientos institucionales y el desarrollo infantil, apuntando a la atención integral de los acogidos.(AU)

Pharmaceutical evaluation of compounded furosemide capsules and excipient performance

Abstract Compounding pharmacies play an important role not only in compounding personalized formulations, but also preparing drugs at the same concentration and dosage as those from commercial manufacturers. The excipients used in compounding are generally standardized for many drugs, however they do not consider the intrinsic properties, such as the poor water solubility, of each substance. The excipient performance of commercially available compounded furosemide capsules in 7 compounding pharmacies from Manaus was evaluated and compared them to the performance of the reference medicinal product (Lasix® tablets) and 2 batches of capsules made in-house (T2 and T4) with a standardized excipient. All batches were subjected to tests for weight variation, assay, uniformity of dosage units, disintegration and dissolution profile. Of the 7 different compound formulas acquired in the compounding pharmacies, only 2 passed all tests. Most formulas passed the tests for weight determination, disintegration time and assay, however batches from 2 establishments failed in regards to the uniformity of the content and 5 batches failed the dissolution test. The reference medicinal product was approved in all tests, as were the T2 capsules made in-house with drug-excipient ratio 1:2. These results confirm the importance of the excipient composition, especially for poorly soluble drugs.

Electric eels galore: microsatellite markers for population studies

Fourteen novel microsatellite loci are described and characterized in two species of electric eels, Electrophorus variiand E. voltaifrom floodplains and rivers of the Amazon rainforest. These loci are polymorphic, highly informative, and have the capacity to detect reliable levels of genetic diversity. Likewise, the high combined probability of paternity exclusion value and low combined probability of genetic identity value obtained demonstrate that the new set of loci displays suitability for paternity studies on electric eels. In addition, the cross-amplification of electric eel species implies that it may also be useful in the study of the closely related E. electricus, and to other Neotropical electric fishes (Gymnotiformes) species as tested herein.(AU)

Catorze novos loci microsatélites são descritos e caracterizados em duas espécies de poraquês, Electrophorus varii e E. voltai de planícies alagadas e rios da floresta amazônica. Esses loci são polimórficos, altamente informativos e têm a capacidade de detectar níveis confiáveis de diversidade genética. Da mesma forma, o alto valor de exclusão de paternidade combinado com a baixa probabilidade de identidade genética demonstra que o novo conjunto de loci exibe adequação para estudos de paternidade em poraquês. Além disso, a amplificação cruzada de espécies de peixes elétricos implica que também pode ser útil no estudo da espécie intimamente relacionada E. electricus, e de outras espécies de peixes elétricos neotropicais (Gymnotiformes).(AU)

Importation and early local transmission of COVID-19 in Brazil, 2020

We conducted the genome sequencing and analysis of the first confirmed COVID-19 infections in Brazil. Rapid sequencing coupled with phylogenetic analyses in the context of travel history corroborate multiple independent importations from Italy and local spread during the initial stage of COVID-19 transmission in Brazil.

Molecular characteristics of methicillin-resistant Staphylococcus aureus isolates from hospital and community environments in northeastern Brazil

ABSTRACT This study characterized 30 MRSA isolates from intensive care unit (ICU) environment and equipment surfaces and healthy children. The SCCmec types I, IVa and V were detected in HA-MRSA isolates while CA-MRSA showed the SCCmec type IVa and V. Most isolates were classified as agr group II. All isolates presented the sei gene, and only HA-MRSA were positive for etb e tst genes. Three genotypes were related to Pediatric (ST5/SCCmecIV) and Berlin (ST45/SCCmecIV) clones. The present study showed molecular similarity between CA- and HA-MRSA isolates in hospital and community settings in a Brazilian region.

Daptomycin and vancomycin non-susceptible methicillin-resistant Staphylococcus aureus clonal lineages from bloodstream infection in a Brazilian teaching hospital

ABSTRACT Introduction: This study aimed to characterize Staphylococcus aureus isolates from bloodstream infections in patients attending a teaching hospital, between 2011 and 2015. Methods: The minimum inhibitory concentration for daptomycin, linezolid, oxacillin, teicoplanin, vancomycin, and trimethoprim/sulfamethoxazole was accessed by broth microdilution. SCCmec type and clonal profile were determined by molecular tests. Vancomycin heteroresistance was evaluated using screening tests and by population analysis profile/area under the curve. Results: Among 200 S. aureus isolates, 55 (27.5%) were MRSA, carrying SCCmec II (45.5%) or IV (54.5%). The most frequent MRSA lineages were USA100 (ST5-II) (45.5%) and USA800 (ST5-IV) (30.9%). Six isolates were confirmed as vancomycin heteroresistant, showing area under the curve ratio 1.1, 1.2 or 1.3 (four USA100, one USA800 and one USA1100 isolates). Conclusions: Daptomycin and vancomycin non-susceptible MRSA clonal lineages were found in bloodstream infections over five years, highlighting the importance of continuous surveillance of multiresistant bacteria in hospitals.

Tomada de decisão de estudantes frente a um case scenario de Endodontia / Students' decision-making in the face of an endodontic case scenario

O presente estudo do tipo transversal avalia o processo de tomada de decisão de estudantes do 4º e 5º anos do curso de Odontologia de uma universidade pública da região Nordeste, frente a um case scenario de Endodontia. A amostra foi constituída por 80 estudantes, os quais, frente ao cenário descrito e imagem radiográfica apresentada, responderam a um questionário sobre o provável motivo da rarefação, a conduta clínica e a tomada de decisão. Para análise dos dados, foram obtidas distribuições absolutas, percentuais uni e bivariadas. A maioria dos pesquisados foi do sexo feminino (55,0%). Analisando a provável causa da rarefação periapical, 43,8% dos entrevistados acreditam que se deva ao limite apical de obturação. A anamnese, o exame clínico e a radiografia foram mencionados como os meios semiotécnicos indicados para a tomada de decisão de tratamento no caso apresentado por 95% dos estudantes. A maioria (60%) decidiu pelo retratamento endodôntico utilizando medicação intracanal. Conclui-se que os estudantes consideram o limite apical de obturação indesejável como motivo da rarefação apical; que a anamnese, exame clínico, exame radiográfico são indicados para a tomada de decisão e optaram pelo retratamento endodôntico. Os estudantes do 5º ano, com mais vivência clínica que os do 4º, apresentaram decisão terapêutica mais conservadora (AU).

This cross-sectional study evaluates the decisionmaking process of students in the 4th and 5th years of the Dentistry course of a public university in the Northeast region, facing a case scenario of Endodontics. The sample consisted of 80 students, who, in view of the described scenario and radiographic image presented, answered a questionnaire about the probable reason for rarefaction, clinical conduct and decision making. For data analysis, absolute distributions, uni, and bivariate percentages were obtained. The majority of respondents were female (55.0%). Analyzing the probable cause of periapical rarefaction, 43.8% of respondents believe that it is due to the apical limit of obturation. Anamnesis, clinical examination, and radiography were mentioned by 95% of the students as the means indicated for the treatment decision-making in the case presented. The majority (60%) decided for endodontic retreatment using intracanal medication. It is concluded that the students consider the undesirable apical limit of obturation as a reason for apical rarefaction; that anamnesis, clinical examination, radiographic examination are indicated for decision making and have chosen endodontic retreatment. The students of the 5th year, with more clinical experience than those of the 4th, presented a more conservative therapeutic decision (AU).
