RESUMO

Mobility is a crucial element in comprehending the possible expansion of the transmission chain in an epidemic. In the initial phases, strategies for containing cases can be directly linked to population mobility restrictions, especially when only non-pharmaceutical measures are available. During the pandemic of COVID-19 in Brazil, mobility limitation measures were strongly opposed by a large portion of the population. Hypothetically, if the population had supported such measures, the sharp rise in the number of cases could have been suppressed. In this context, computational modeling offers systematic methods for analyzing scenarios about the development of the epidemiological situation taking into account specific conditions. In this study, we examine the impacts of interstate mobility in Brazil. To do so, we develop a metapopulational model that considers both intra and intercompartmental dynamics, utilizing graph theory. We use a parameter estimation technique that allows us to infer the effective reproduction number in each state and estimate the time-varying transmission rate. This makes it possible to investigate scenarios related to mobility and quantify the effect of people moving between states and how certain measures to limit movement might reduce the impact of the pandemic. Our results demonstrate a clear association between the number of cases and mobility, which is heightened when states are closer to each other. This serves as a proof of concept and shows how reducing mobility in more heavily trafficked areas can be more effective.

RESUMO

The evaluation of the reactivity and distress of cattle during corral management, by means of subjective scores, aims at the standardization of behavioral indicators, through non-invasive methods, in addition to enabling the development of more appropriate management practices, thus promoting the comfort and well-being of these animals. Therefore, in this study, we aimed to characterize the temperament and distress of cattle managed in a corral using behavioral indicators during the rainiest period. For this, the experiment was conducted on a property located in the municipality of Mojuí dos Campos, during the rainiest quarter (February-April). Thus, 30 male cattle, not castrated, approximately 29 months of age, clinically healthy, and weighing 310 + 20 kg, were divided into three rearing systems: silvopastoral (SP), traditional (SS), and integrated (SI) systems. There were 10 animals per system. Physiological parameters were collected to evaluate rectal temperature (RT) and respiratory rate (RR), as well as body surface temperature (BST), through thermal windows (head and flank infrared temperature and rump infrared temperature). To evaluate temperament and reactivity, scores indicative of corral behavior were used, namely escape speed (ES), tension score (SS_1), tension score (SS_2), reactivity scale (RS), movement score (MS), and temperament scale (TS). The results showed that there was a thermal amplitude of 5.9 °C on average and 8.6 °C at maximum when comparing the structure of the corral and the trees. In addition, the comparisons between the production systems for the behavioral variables did not differ at the 5% significance level, except for ES, where the traditional system differed from the integrated system and the silvopastoral system, showing intermediate average values for both. In addition, there was a positive correlation between the variables RT and RR (r = 0.72; p < 0.01), RR and SS_2 (r = 0.38; p = 0.04), flank infrared temperature and MS (r = 0.47; p = 0.01), rump infrared temperature and RS (r = 0.37; p = 0.04), SS_1 and RS (r = 0.41; p = 0.02), SS_1 and SS_2 (r = 0.39; p = 0.03), RS and SS_2 (r = 0.58; p = 0.00), RS and MS (r = 0.50; p = 0.01), RS and TS (r = 0.61; p = 0.00), SS_2 and MS (r = 0.51; p = 0.00), SS_2 and TS (r = 0.47; p = 0.01), and MS and TS (r = 0.44; p = 0.02), and a negative correlation between ES and TS (r = -0.42; p = 0.02). The rainy season had a major influence on the evaluation of temperature and distress levels during handling in the corral, as evidenced by the association between physiological and behavioral parameters.

RESUMO

Introduction: Although the United States and other countries have implemented comprehensive legislation, regulations, and policies to support biosafety and biosecurity of high- and maximum-containment laboratories, Brazil's legislation has notable gaps and inconsistencies. Objective: To evaluate the Brazilian approach to ensuring nationwide biosafety and biosecurity oversight and governance of high- and maximum-containment laboratories. Methods: A systematic gap analysis was conducted to compare Brazilian biosafety and biosecurity legislation, regulations, and policies with their international counterparts, with a particular focus on the oversight and governance of high- and maximum-containment laboratories. Results: We found that Brazilian biosafety and biosecurity legislation, regulations, and policies have relevant gaps. Governance and regulatory oversight of Brazil's high- and maximum-containment laboratories are decentralized with variable levels of adherence to commonly accepted global biosafety and biosecurity compliance standards. These findings represent a limitation not only to governance but also to the preparedness to face current and future challenges related to emergent infectious diseases in Brazil. Enhancing the Brazilian legal framework on laboratory biosafety and biosecurity is necessary and urgent. Reviewing the lessons learned and regulations applied in the United States and other international frameworks helped identify potential areas for improving Brazil's ability to inventory and manage its diverse biocontainment laboratory capabilities and assure these valuable resources align with national needs and priorities. Conclusion: The Brazilian government has an opportunity to revise and improve upon a national set of legislation, regulations, and policies for its high- and maximum-containment laboratories, taking advantage of legislation and guidelines published by other countries.

RESUMO

This study aimed to assess whether patients feel safe or anxious when receiving dental care at a teaching clinic; the study was carried out from the perspective of patients, given the biosafety protocol during the 2019 Coronavirus (COVID-19) pandemic. Thiscross-sectional study was carried out with 217 patients assisted by students in the Dental Clinic of the Pontifícia Universidade Católica do Paraná. A semi-structured questionnaire was used to collect sociodemographic data, humanization and the safety protocols followed during care. Multivariate analysis was performed using Poisson regression (PR), and p values ≤0.05 were understood. Around 90% of patients reported that students were attentive, communicative, welcoming and confident during treatment about the risk of contracting COVID-19 during care. Patients who showed anxiety during treatment were 32.2%. Some patients were unable to keep their distance in the waiting room (PR 3.439) and did not feel safe during the appointment (PR 2.64) had a higher prevalence of anxiety during dental care. Anxiety about care was associated with the individual's color or ethnicity, ability to maintain social distancing in the waiting room, and feeling safe when receiving care (AU).

Metodología: Se realizó una investigación descriptiva observacional de corte transversal en el servicio Ortodoncia de la Clínica Estomatológica Docente Provincial Dr. Justo Ortelio Pestana Lorenzo de la provincia Sancti Spíritus, desde septiembre 2019 a febrero 2022. Se seleccionaron 20 pacientes que iniciaron su etapa de contención en este período y cumplieron los criterios de inclusión. Se utilizaron métodos del nivel empírico y estadístico. Se analizaron las variables: edad, sexo, variables morfológicas clínicas y cefalométricas, así como resultado de la contención. Resultados: Se constató una edad promedio de 15.6; el 65 % de los escolares pertenecían al sexo femenino. Al año de iniciada la contención se mantuvo el sobrepase incisivo en 2.95 mm, la relación molar de neutroclusión en el 65 %, ángulo SNB en 79°, el ángulo ANB en 2.80°, la posición del incisivo superior 2.45 mm, la posición del incisivo inferior en 1.90 mm y el perfil estético en 0.55 mm. Solo existió incremento en el valor promedio del resalte incisivo de 2.70 mm a 2.75 mm. Conclusiones: Al año de iniciada la contención con el aparato funcional postratamiento de Waveney no se observó modificación de las variables estudiadas, excepto el resalte incisivo con incremento de su valor promedio.


Background: For mandibular advancement containment, it is necessary to use an appliance that holds the jaw in the achieved position by active appliances and that its design does not provoke undesired dental movements. Objective: To describe the clinical and cephalometric changes of the Orthodontic Appliances after the Waveney treatment as an alternative in the mandibular advancement containment. Methodology: A descriptive observational cross-sectional research was conducted at the Dr. Justo Ortelio Pestana Lorenzo Provincial Teaching Stomatology Clinic orthodontic service in Sancti Spíritus province, from September 2019 to February 2022. 20 patients who started their containment stage in this period and fulfilled the inclusion criteria were selected. Empirical and statistical methods were used. The following variables were analyzed: age, sex, clinical morphological and cephalometric variables, as well as the containment result. Results: An average age of 15.6 was found; 65% of the schoolchildren were female. One year after the containment was started, the incisive overpass was maintained at 2.95 mm, the neutroclusion molar rate at 65%, SNB angle at 79°, the ANB angle at 2.80°, the upper incisor position 2.45 mm, the lower incisor position by 1.90 mm and the esthetic profile by 0.55 mm. There was only an average increase in the incisor protrusion value from 2.70 mm to 2.75 mm. Conclusions: One year after containment with the Waveney post-treatment Orthodontic Appliances was initiated no changes were observed in the studied variables, except for incisor protrusion with an increase in its average value.

RESUMO

Descorna cirúrgica em bovinos é uma prática bastante realizada na medicina veterinária, com indicação principalmente para evitar acidentes com fraturas, trabalhadores e outros animais. O objetivo do presente relato seria ressaltar o uso de analgésicos e sedativos em bovinos submetidos a este procedimento cirúrgico, compartilhar técnica cirúrgica utilizada, informações de monitoramento de sinais vitais no trans cirúrgico e recomendações pré, trans e pós-cirúrgicas, assim como possíveis complicações. Foi atendido um bovino da raça Jersey, fêmea, 1 ano de idade, pesando cerca de 222kg, submetido a descorna bilateral devido ao comportamento agressivo. Contido em tronco de contenção e tranquilizado com acepromazina, recebeu meloxicam e associação de sulfa com trimetropim. Após tricotomia e antissepsia foi realizado bloqueio perineural do ramo cornual do nervo zigomático temporal e bloqueio infiltrativo ao contorno de cada corno com lidocaína sem vasoconstritor. Com os cornos insensíveis, se deu início ao procedimento de descorna cirúrgica pela associação das técnicas de serra de gigli com o alicate do tipo Dick Kaber. Concluímos ser de extrema importância a execução da técnica cirúrgica por médico veterinário apto, realizando o procedimento de forma asséptica e com analgesia visando o bem estar do animal. No caso em questão, a associação das técnicas de serra de gigli com o alicate do tipo Dick Kaber foi parcialmente satisfatória, o animal apresentou boa margem de fechamento da sutura e sem deiscência dos pontos, porém houve dificuldades de retirada de margens ósseas pontiagudas após uso do alicate. A tranquilização associada ao bloqueio local foi efetiva para tal procedimento.(AU)


Surgical dehorning in cattle is widely performed practice in veterinary medicine, primarily indicated to prevent accidents involving workers, fights between animals, and skull fractures. This procedure involves the removal of the horns of the horns of cattle and should be performed using ethical methods by a qualified veterinarian. The objective of this case report is to highlight the use of analgesics and sedatives in cattle undergoing this surgical procedure, share the surgical technique employed, information on vital sign monitoring during the procedure, and pre-, intra-, and post-surgical recommendations, as well as potential complications. A Jersey cattle, female, 1 year old, weighing approximately 222kg, underwent bilateral dehorning due to aggressive behavior. Restrained in a cattle chute and tranquilized with acepromazine, she received meloxicam and a combination of sulfadiazine with trimethoprim. After trichotomy and antiseptic preparation, perineural blockade of cornual branch of the zygomatic temporal nerve was performed, follows by infiltrative blockade around each horn with lidocaine without vasoconstrictor. With the horns desensitized, the surgical dehorning procedure began using a combination of Gigli saw and Dick Kaber-type wire snare. In conclusion, it is of utmost importance for the surgical technique to be performed by a qualified veterinarian, ensuring aseptic procedure and correct analgesia for the well-being of the cattle. In this case, the combination of Gigli saw and Dick Kaber-type wire snare was partially satisfactory; the animal had a good suture closure margin and did not present suture dehiscence, but there were difficulties in we moving pointed bony margins after using the wire snare. Tranquilization combined with local blockade was effective for this procedure.(AU)

El objetivo de este informe sería resaltar el uso de analgésicos y sedantes en bovinos sometidos a este procedimiento quirúrgico, compartir la técnica quirúrgica utilizada, información sobre el monitoreo de signos vitales durante la cirugía y recomendaciones pre, trans y posquirúrgicas, así como posibles complicaciones. Se trata de una hembra bovina Jersey, de 1 año de edad, con un peso aproximado de 222 kg, siendo sometida a descornado bilateral por comportamiento agresivo. Se recibieron contenidos en un baúl de contención y tranquilizados con acepromacina, meloxicam y una combinación de sulfas y trimetopim. Mediante tricotomía y antisepsia se realizó bloqueo perineural de la rama cornual del nervio temporal cigomático y bloqueo infiltrativo en todo el contorno de cada miembro con lidocaína sin vasoconstrictor. Con cuerpos insensibles se inició el procedimiento de descornado quirúrgico, combinando técnicas de aserrado con alicates Dick Kaber. Concluimos que es de suma importancia realizar la técnica quirúrgica por un veterinario calificado, realizando el procedimiento de manera aséptica y con analgesia administrada para el bienestar del animal. En el caso que nos ocupa, la asociación de técnicas de la sierra con la pinza tipo Dick Kaber fue parcialmente satisfactoria, el animal presentó un buen margen de cierre de sutura y ninguna dehiscencia de los puntos, sin embargo, hubo dificultades para eliminar los márgenes óseos afilados después de usar alicates La tranquilidad asociada al bloqueo local fue eficaz para este procedimiento.(AU)

RESUMO

Abstract The study aimed to compare the adherence of Brazilian and Italian pediatric dentists to the biosafety measures and operative protocols recommended by the health authorities during COVID-19 pandemic and to classify the participants according to their risk of infection. An online questionnaire with 34 questions about sociodemographic and occupational data, dental practice organization, biological risk management, and clinical operative protocols was sent to Brazilian and Italian pediatric dentists using a convenience sampling strategy. Chi-square test and multivariate analysis (two-step cluster) were performed (α = 5%). Of 641 respondents (377 Brazilians and 264 Italians), most were female (94% and 70%, respectively), aged 20-39 years (63%), with over 10 years of professional experience (58% and 49%, respectively). Based on adherence to recommended biosafety measures, participants were classified as "safer" (n = 219) or "less safe" (n = 422). Adherence to recommended protocols by the majority of participants resulted in low contagion rates (Brazilians = 5%; Italians = 12.5%). Participants with extensive professional experience in the dental setting exhibited a greater tendency to implement multiple adaptations (three or more) in their practice. Most participants (Brazilians = 92%; Italians = 80.7%) adopted the recommended minimal intervention dentistry approaches, with the use of fissure sealants and the use of non-rotary instruments for caries removal the most frequently techniques used among Brazilians (36%) and Italians (66%), respectively. Two different profiles of pediatric dentists were identified based on the biosafety protocols adopted during the pandemic. In addition, changes were implemented in the dental care provided to children, with focus on the minimal intervention dentistry.

RESUMO

The analysis of curated genomic, metagenomic and proteomic data is of paramount importance in the fields of biology, medicine, education, and bioinformatics. Although this type of data is usually hosted in raw format on free international repositories, the full access requires lots of computing power and large storage disk space for the domestic user. The purpose of the study is to offer a comprehensive set of microbial genomic and proteomic reference databases in an accessible and easy-to-use form to the scientific community and demonstrate its advantages and usefulness. Also, we present a case study on the applicability of the sketched data, for the determination of overall genomic coherence between two members of the Brucellacea family, which suggests they belong to the same genomospecies that remain as discrete ecotypes. A representative set of genomes, proteomes (from type material), and metagenomes were directly collected from the NCBI Assembly database and Genome Taxonomy Database (GTDB), associated with the major groups of Bacteria, Archaea, Virus, and Fungi. Sketched databases were subsequently created and stored on handy reduced representations by using the MinHash algorithm implemented in Mash software. The obtained dataset contains more than 133 GB of space disk reduced to 883.25 MB and represents 125,110 genomics/proteomic records from eight informative contexts, which have been prefiltered to make them accessible, usable, and user-friendly with limited computational resources. Potential uses of these sketched databases are discussed, including but not limited to microbial species delimitation, estimation of genomic distances and genomic novelties, paired comparisons between proteomes, genomes, and metagenomes; phylogenetic neighbor's exploration and selection, among others.


A análise de dados genômicos, metagenômicos e proteômicos com curadoria é de suma importância nos campos da biologia, medicina, educação e bioinformática. Embora esse tipo de dados geralmente seja hospedado em formato bruto em repositórios internacionais gratuitos, o acesso total requer muita capacidade de computação e grande espaço em disco de armazenamento para o usuário doméstico. Os objetivos do estudo são oferecer um conjunto abrangente de bancos de dados de referência genômica e proteômica microbiana de forma acessível e fácil de usar para a comunidade científica e demonstrar suas vantagens e utilidade. Além disso, apresentamos um estudo de caso sobre a aplicabilidade dos dados esboçados para a determinação da coerência genômica geral entre dois membros da família Brucellacea, o que sugere que eles pertencem às mesmas genomoespécies que permanecem como ecótipos discretos. Um conjunto representativo de genomas, proteomas (de material tipo) e metagenomas foi coletado diretamente do banco de dados NCBI Assembly e do banco de dados de taxonomia do genoma (GTDB), associada aos principais grupos de bactérias, Archaea, vírus e fungos. Bancos de dados esboçados foram subsequentemente criados e armazenados em representações reduzidas práticas usando o algoritmo MinHash implementado no software Mash. O conjunto de dados obtido contém mais de 133 GB de espaço em disco reduzido para 883,25 MB e representa 125,110 registros genômicos/proteômicos de oito contextos informativos, que foram pré-filtrados para torná-los acessíveis, utilizáveis ​​e amigáveis ​​com recursos computacionais limitados. Os usos potenciais desses bancos de dados esboçados são discutidos, incluindo, mas não se limitando, a delimitação de espécies microbianas, estimativa de distâncias genômicas e novidades genômicas, comparações emparelhadas entre proteomas, genomas e metagenomas, exploração e seleção filogenética de vizinhos, entre outros.

RESUMO

Despite the undeniable effect of vaccination against COVID-19 in reducing disease severity, there is still a need to monitor and limit SARS-CoV-2 circulation and transmission. Thus, this study evaluated the presence of the SARS-CoV-2 genome on the surfaces of highly touched objects manipulated in the biological sample collection point and at the reception unit of the diagnostic laboratory. Surfaces were sampled once a week, for 6 weeks, between September 18th and October 23rd, 2020. RT-qPCR was used for SARS-CoV-2 detection. The coolers for biological sample transportation and the envelope containing the patient form were the objects with the highest occurrence of viral genome detection, although it was detected in each object in only two of the 6 evaluations. And the SARS-CoV-2 genome was detected just once on the vehicle steering wheel, computer keyboard, bathroom door handle and disinfection bench. The virus genome was not detected in any object on three of the six evaluations. And eight was the largest number of surfaces contaminated by the virus genome on one occasion. The reduced incidence of object contamination by the SARS-CoV-2 genome can be explained by the exposure of the objects to environmental conditions and the adoption of virus-spread containment measures. It can also reflect the low incidence of SARS-CoV-2 during the study's development period. Despite the low frequency of SARS-CoV-2 genome detection, our findings show that the virus was present in the environment at some point. This highlights the importance of adopting personal preventive measures to reduce respiratory virus spread, especially during epidemics and outbreaks.

RESUMO

Objectives: The study aims to understand the impact of containment policy and mobility on COVID-19 cases in Chile, Singapore, South Korea and Israel. To provide experience in epidemic prevention and control. Methods: Structural equation modeling (SEM) of containment policies, mobility, and COVID-19 cases were used to test and analyze the proposed hypotheses. Results: Chile, Israel and Singapore adopted containment strategies, focusing on closure measures. South Korea adopted a mitigation strategy with fewer closure measures, focusing on vaccination and severe case management. There was a significant negative relationship among containment policies, mobility, and COVID-19 cases. Conclusion: To control the COVID-19 and slow down the increase of COVID-19 cases, countries can increase the stringency of containment policies when COVID-19 epidemic is more severe. Thus, countries can take measures from the following three aspects: strengthen the risk monitoring, and keep abreast of the COVID-19 risk; adjust closure measures in time and reduce mobility; and strengthen public education on COVID-19 prevention to motivate citizen to consciously adhere to preventive measures.

RESUMO

Introducción: Las Infecciones Asociadas a la Atención en Salud (IAAS) son un serio problema para los establecimientos de salud, no solo como causal de morbimortalidad sino también por los altos costos que generan. La contaminación de ambientes son un peligro para cualquier establecimiento sanitario. Objetivo: Determinar la eficacia de los desinfectantes de uso hospitalario frente a microorganismos aislados de superficies (respirador, monitor y superficie de la cama clínica) de áreas críticas del Hospital Santa Rosa, Lima, Perú. Material y Métodos: Estudio observacional, prospectivo y transversal, se evaluaron varios productos de desinfección de superficies. Se utilizó la prueba de reto en superficie utilizando cepas control. Las muestras fueron recolectadas de los servicios de Unidad de Cuidados Intensivos Adultos (UCI), Unidad de Cuidados Intensivos Neonatal (UCINEO), Unidad de Cuidados Especiales de Medicina (UCEM) del Hospital San Rosa. El efecto de los desinfectantes evaluados se realizó a los 5, 10 y 15 minutos. Resultados: En las condiciones del ensayo y considerando los tiempos y velocidad de muerte bacteriana por efecto del desinfectante, los productos de mayor eficacia resultaron ser el amonio cuaternario (Supersafe D) e hipoclorito de sodio a 1 por ciento. Conclusiones: Ninguno de los desinfectantes logró alcanzar las exigencias del test de Chambers. Los productos lograron efectos esperados a partir de los 10 ó15 minutos(AU)


Introduction: Infections Associated with Health Care (IAAS) are a serious problem for health care facilities, not only as a cause of morbidity and mortality but also because of the high costs they generate. Contaminated environments are a danger for any health care facilities. Objective: To determine the efficacy of hospital disinfectants against microorganisms isolated from surfaces (ventilator, monitor and surface of the hospital bed) in critical areas of the "Santa Rosa" Hospital, Lima-Peru. Material and Methods: An observational, prospective and cross-sectional study was conducted to evaluate disinfection products used to clean floors and surfaces. The surface challenge test was performed using control strains. Samples were collected from the adult intensive care unit (ICU), the neonatal intensive care unit (NICU) and the special care unit (SCU) of the Santa Rosa Hospital. The effect of the disinfectants was evaluated at the fifth, tenth and fifteen minutes. Results: Under the study conditions and considering the time and speed of bacterial death due to the disinfectant effect, the most effective products were quaternary ammonium (Supersafe-D) and 1 percent sodium hypochlorite. Conclusions: None of the disinfectants met the chamber test requirements. The products achieved the expected effects after 10 to 15 minutes(AU)

RESUMO

Due to the COVID-19 emergency, face-to-face classes were suspended. After the vaccination of teachers and to mitigate educational backwardness, the schools have begun to reopen with protocols established by the government. Here, we investigated the COVID-19 outbreak in summer courses during the reopening of a private elementary school in July 2021. We report confirmed cases of COVID-19 in staff members, students, and their families. A total community of 290 people was part of this study, and we built the contact network. The clinical features of all cases are described. We used the methodology of cases and contacts. The index case was identified by epidemiological tracking, and containment measures were activated, as well as further infection chains in the setting. We estimate the attack rate for staff members at 15.68% (95% CI 7.0-28.6), students at 12.24% (95% CI 4.6-24.8), and family members at 2.6% (95% CI 0.8-6.0). An incubation period of 48-72 h was determined. A student-teacher-student-family transmission sequence was identified. The area where the infection was identified was the school swimming pool, an area where face masks are not worn or, in some cases, inadequately used. Finally, we continue with intermittent staff testing and early detection actions, reinforcing prevention measures, environmental control, cleaning, and educational interventions with students regarding the implementation of preventive measures through classes led by school health staff.

RESUMO

Introduction: the first COVID-19 case in Brazil was confirmed on February 26, 2020. As of March 17, 2023, the Ministry of Health reported 699,634 deaths from COVID-19, with a case fatality rate of 1.9%. The impact of the COVID-19 pandemic in Brazil extends to socioeconomic and healthcare systems, reflecting significant regional disparities. Objective: To analyze mortality, incidence, and case fatality rates for COVID-19 in the states of Paraná and Santa Catarina, in the southern region of Brazil. Methods: This is an ecological time-series study using official Brazilian secondary data for COVID-19 cases and deaths. Data were extracted from the dashboard of the State Health Department of Santa Catarina and Paraná. Temporal series were developed for trend analysis using the Prais-Winsten regression model. Statistical analyses were performed using STATA 14.0 software (College Station, TX, USA, 2013). Results: In the analysis of rates over the entire period, trends for mortality, case fatality, and incidence in the state of Santa Catarina are decreasing, decreasing, and stationary, respectively. In Paraná, rates over the entire period showed a stationary trend for mortality, decreasing for case fatality, and increasing for incidence. Conclusion: COVID-19 had a devastating effect on the states of Santa Catarina and Paraná. Both states experienced the progression of the COVID-19 pandemic, with higher case fatality and mortality rates observed in Paraná, while Santa Catarina had a higher incidence rate over the three years of the COVID-19 pandemic.

RESUMO

Fraturas ósseas e luxações são mais comuns em animais jovens e, na maioria das vezes, essas fraturas ocorrem devido ao manejo incorreto desses animais, podendo levar a uma queda de produção a curto ou longo prazo, gerando perdas econômicas e produtivas de animais de alto padrão genético. Nesse contexto, o objetivo deste trabalho foi relatar a ocorrência de uma fratura na região metacarpiana do membro torácico esquerdo de uma bezerra Gir de 12 dias de idade, causada por uma contenção ineficaz durante a pesagem. O animal proveniente de uma fazenda em Umirim/CE foi encaminhado ao Hospital Veterinário de Grandes Animais do Centro Universitário INTA em Sobral/CE. Ao passar pelo exame radiográfico, foi constatada a fratura na região metacarpiana do membro torácico esquerdo. O animal foi imobilizado de forma manual, seguindo-se métodos semiológicos para minimizar o estresse. Para a imobilização do membro, foi utilizada a muleta de Thomas modificada e bandagens, associadas ao controle da dor com as drogas Flunixin meglumine (1,1mg/kg) e Fenilbutazona (4,4mg/kg). Depois da imobilização, o animal seguiu internado no HOVET-GA e, após 18 dias, foi realizada uma nova radiografia para ver o progresso a partir do tratamento adotado. Constatou-se a formação de um calo ósseo, com a ossificação da fratura, não sendo necessário o encaminhamento cirúrgico do animal. Assim, o tratamento com muleta de Thomas modificada foi efetivo para a recuperação do membro fraturado, além de ser um tratamento de baixo custo e fácil aplicação, tendo o animal apresentado uma boa resposta ao tratamento terapêutico para controle da dor.


Bone fractures and dislocations are more common in young animals and mostly occur due to incorrect handling of these animals, which can lead to a short or long-term drop in production, generating economic and productive losses of animals of high genetic standard. This study aimed to report the occurrence of a fracture in the metacarpal region of the left thoracic limb of a 12-day-old Gir heifer, caused by an ineffective restraint during weighing. The animal from a farm in Umirim/CE was sent to the Veterinary Hospital of Large Animals of the University Center INTA in Sobral/CE. The radiographic examination found a fracture in the metacarpal region of the left thoracic limb. The animal was manually immobilized following semiological methods to minimize stress. For the limb immobilization, a modified Thomas crutch and bandages associated with pain control with the drugs Flunixin meglumine (1.1mg/kg) and Phenylbutazone (4.4mg/kg) were used. After immobilization, the animal remained hospitalized at HOVET-GA and after 18 days a new radiograph was performed to evaluate the progress achieved with the treatment adopted. It was found the formation of a bone callus with the ossification of the fracture, not requiring the surgical referral of the animal. Thus, the treatment with the modified Thomas crutch was effective for the recovery of the fractured limb, in addition to being a low-cost and easy-to-apply treatment. The animal showed a good response to the therapeutic treatment for pain control.

RESUMO

According to the social stress process model, global crises are macro-level stressors that generate physiological stress and psychological distress. However, existing research has not identified immigrants' COVID-19 containment policy stressors or examined the social stress of sending remittances amid crises. Drawing on in-depth longitudinal interviews with 46 Venezuelan immigrants-half before and half during the pandemic-in Chile and Argentina, we identified the COVID-19 containment policies' stressors. We focused on Venezuelan immigrants because they constitute one of the largest internationally displaced populations, with most migrating within South America. We found that the governmental COVID-19 containment measures in both countries generated four stressors: employment loss, income loss, devaluation of employment status, and inability to send needed remittances. Moreover, sending remittances helped some migrants cope with concerns about loved ones in Venezuela. However, sending remittances became a social stressor when immigrants struggled to simultaneously sustain their livelihoods and send financial support to relatives experiencing hardships in Venezuela. For some immigrants, these adversities generated other stressors (e.g., housing instability) and symptoms of anxiety and depression. Broadly, for immigrants, the stressors of global crises transcend international borders and generate high stress, which strains their psychological well-being.

RESUMO

OBJETIVO: Descrever o conhecimento dos estudantes de enfermagem sobre as medidas de biossegurança no contexto hospitalar em tempos de pandemia. MÉTODO: Estudo descritivo, exploratório, qualitativo, com estudantes de enfermagem de uma universidade pública da baixada litorânea do Rio de Janeiro, Brasil, através de entrevista em ambiente virtual, entre julho e setembro de 2021. Utilizou-se o Interface de R pour Analyses Multidimensionnelles de Textes Et de Questionnaires para processamento do corpus textual e Análise de Conteúdo Temática para interpretação das falas. RESULTADOS: Participaram 29 estudantes que reconhecem a biossegurança, mas não possuem segurança ao abordá-la. Para eles, trata-se de normas para proteção do trabalhador e pacientes, associando-as aos EPIs e ao uso durante a pandemia. CONCLUSÃO: A biossegurança não é reconhecida na sua totalidade entre estudantes de enfermagem que estarão no mercado de trabalho futuramente. É necessário um olhar ampliado em perspectiva transversal, especialmente nas disciplinas do ciclo profissionalizante da enfermagem.


OBJECTIVE: To describe Nursing students' knowledge about the biosafety measures in the hospital context in pandemic times. METHOD: A descriptive, exploratory and qualitative study conducted through interviews in a virtual environment between July and September 2021 with Nursing students from a public university in the coastal lowland of Rio de Janeiro, Brazil. Interface de R pour Analyses Multidimensionnelles de Textes Et de Questionnaires was used to process the text corpus and Thematic Content Analysis was employed to interpret the testimonies. RESULTS: The participants were 29 students that recognize biosafety but are not confident enough to address it. For them, it is but a set of standards for the protection of workers and patients alike, associating it with PPE and with its use during the pandemic. CONCLUSION: Biosafety is not recognized in its entirety by the Nursing students who will enter the labor market in the near future. An expanded and cross-sectional perspective is required, especially in the academic disciplines of Nursing training cycle.

RESUMO

A pandemia da COVID-19 impôs desafios importantes para a formação dos futuros enfermeiros no que tange aos conhecimentos e habilidades necessárias sobre as medidas de biossegurança dos equipamentos de proteção individual. Diante disto, neste estudo objetivou-se avaliar a efetividade da intervenção educativa no conhecimento e habilidade técnica de estudantes de enfermagem sobre paramentação e desparamentação e medidas preventivas no contexto da COVID-19 antes e após intervenção educativa. Trata-se de um estudo misto, composto de duas etapas. Na primeira etapa, foi conduzido um estudo metodológico de junho a setembro de 2021 com a construção e validação Exame Clínico Objetivo Estruturado (OSCE) por 22 juízes, foram convidados via e-mail através do Google Forms para validar os instrumentos. E a segunda etapa, consistiu em um estudo quase-experimental tipo antes e depois, de junho a agosto de 2022, constituído por 80 estudantes de enfermagem regularmente matriculados em uma instituição de ensino superior do interior de São Paulo, do segundo ao quarto ano, aplicando teste de conhecimento (pré e pós teste), intervenção educativa, OSCE sobre paramentação e desparamentação, uso de escalas acerca de precauções padrão e medo da COVID-19, dados analisados por meio de estatística descritiva e inferencial. Para verificar se houve diferença entre pré e pós-teste das escalas CSPS, SPQ-PB e escala de Medo, além de verificar se houve associação entre as variáveis sociodemográficas e o conhecimento, foi realizado o Teste de Wilcoxon. Para comparar possíveis diferenças nos acertos no teste de conhecimento entre pré e pós, foi utilizado o Teste de Mcnemar, em todos adotou-se um nível de significância de α ≤0,05. Na etapa I, obteve-se a validação do OSCE por juízes/especialistas, onde o IVC relativo à objetividade e conteúdo foi de 0,95 e 1; IVC de 0,82 e 0,95 referente à clareza e avaliação geral. A intervenção educativa mostrou-se efetiva sobre o aumento do conhecimento dos estudantes, as variáveis com associações significantes foram: sexo feminino, pertencer ao Curso de Bacharelado em Enfermagem. Houve aumento nos acertos em 14 questões, onde em sete identificou-se diferença estatisticamente significante. Quanto ao desempenho dos estudantes observou-se que os estudantes tiveram maiores acertos nas etapas da paramentação comparado a desparamentação, em nenhuma das etapas da desparamentação foi alcançado 100% de acertos. Observou-se que 78 (97,5%) se autocontaminaram durante a realização da desparamentação dos EPI e apenas 2 (2,5%) não se autocontaminaram. Quanto a avaliação do cumprimento às PP por meio da escala CSPS tanto no pré-teste como no pós-teste, encontrou-se que oito itens obtiveram taxas de cumprimento acima de 80%. Entre os fatores que facilitam a adesão às PP, 77 (96,3%) dos estudantes afirmaram ser totalmente eficaz estar capacitado no que se refere às precauções-padrão tanto no pré como no pós-teste e redução do medo de morrer de COVID-19 para 17,5%. Assim, foi percebida a melhora conhecimento e habilidades acerca da paramentação e desparamentação de EPI, das medidas preventivas sobre COVID-19 pelos estudantes de enfermagem, além de esmiuçar as áreas com maiores presenças de autocontaminação simulada após a desparamentação


The COVID-19 pandemic has imposed significant challenges for the education of future nurses regarding the necessary knowledge and skills regarding biosafety measures and personal protective equipment. Therefore, this study aimed to evaluate the effectiveness of an educational intervention on the knowledge and technical skills of nursing students on donning and doffing, as well as preventive measures in the context of COVID-19, before and after the intervention. This mixed-methods study consisted of two stages. In the first stage, a methodological study was conducted from June to September 2021, involving the construction and validation of the Objective Structured Clinical Examination (OSCE) by 22 judges. The judges were invited via email using Google Forms to validate the instruments. The second stage consisted of a quasi-experimental pre- and post-test study conducted from June to August 2022, involving 80 nursing students regularly enrolled in a higher education institution in the interior of São Paulo, Brazil. The students were in their second to fourth year of study. The study included a knowledge test (pre- and post-test), an educational intervention, OSCE donning and doffing, the use of scales regarding standard precautions and fear of COVID-19. The data were analyzed using descriptive and inferential statistics. The Wilcoxon test was used to verify if there was a difference between the pre- and post-test scores of the scales CSPS (Compliance with Standard Precautions Scale), SPQ-PB (Standard Precautions Questionnaire-Perceived Barrier Scale), and Fear Scale. The association between sociodemographic variables and knowledge was also examined. The McNemar test was used to compare possible differences in knowledge test scores between the pre-and post-tests. A significance level of α ≤0.05 was adopted for all analyses. In Stage I, the OSCE was validated by judges/experts. The Content Validity Index (CVI) for objectivity and content was 0.95 and 1, respectively. The CVI for clarity and overall evaluation was 0.82 and 0.95, respectively. The educational intervention was effective in increasing students' knowledge. The variables with significant associations were female gender and enrollment in the Bachelor of Nursing program. There was an increase in correct answers for 14 questions, with statistically significant differences observed in seven questions. Regarding student performance, it was observed that students had higher scores in the donning stages compared to the doffing stages. None of the doffing stages achieved 100% accuracy. It was observed that 78 (97.5%) students self-contaminated during the doffing, while only 2 (2.5%) did not self-contaminate. Regarding compliance with standard precautions, as evaluated by the CSPS scale in both the pre- and post-tests, eight items achieved compliance rates above 80%. Among the factors that facilitate adherence to standard precautions, 77 (96.3%) students reported that being trained in standard precautions was fully effective, both in the pre- and post-tests. The fear of dying from COVID-19 decreased by 17.5%. Thus, an improvement in knowledge and skills on donning and doffing, as well as preventive measures for COVID-19, was observed among nursing students. The areas with the highest presence of simulated self-contamination after doffing were also identified

RESUMO

Objetivos: identificar fatores associados à acidentes com material biológico e à percepção do risco biológico entre Agentes Comunitários de Saúde (ACS). Métodos: estudo transversal analítico realizado com ACS, mediante aplicação de questionário e consulta de registros no cartão de vacinas. Regressão múltipla de Poisson com variância robusta foi realizada para analisar os fatores associados aos acidentes com material biológico e à percepção do risco biológico. Resultados: dos 207 participantes, 50,24% (IC 95% = 43,4 - 56,9) apresentou autorrelato de acidentes com material biológico, tendo como fatores associados possuir formação de nível superior [RP ajustada = 2,2 (IC 95% = 1,0 - 4,7)], ter outro vínculo empregatício [RP ajustada = 1,5 (IC 95% = 1,0 - 2,3)] e conhecimento quanto às vacinas necessárias ao ACS [RP ajustada = 0,7 (0,5 - 0,9)]. Constatou-se que 74,39% dos ACS tinham percepção de algum risco biológico, mesmo de forma limitada. Entre as variáveis investigadas, na análise ajustada, nenhuma mostrou associação com a percepção de risco biológico pelos ACS. Conclusão: a prevalência de acidentes com material biológico em ACS é elevada, sendo fatores associados possuir formação de nível superior, ter outro vínculo empregatício e apresentar conhecimento quanto as vacinas necessárias para a atividade laboral. Há limitada percepção de risco pela maioria dos ACS. Não foram encontrados fatores associados à esta variável.


Objectives: to identify factors associated with accidents involving biological material and the perception of biological risk among community health workers (CHWs). Methods: an analytical cross-sectional study was carried out with CHWs using a questionnaire and consultation of vaccination card records. Poisson multiple regression with robust variance was conducted to analyze the factors associated with accidents involving biological material and perception of biological risk. Results: of the 207 participants, 50.24% (95% CI = 43.4 - 56.9) self-reported accidents with biological material, and the associated factors were having a university degree [adjusted PR = 2.2 (95% CI = 1.0 - 4.7)], having another job [adjusted PR = 1.5 (95% CI = 1.0 - 2.3)] and knowledge of the vaccines needed by CHWs [adjusted PR = 0.7 (0.5 - 0.9)]. It was found that 74.39% of CHWs were aware of some biological risk, even to a limited extent. Among the variables investigated, in the adjusted analysis, none showed an association with the perception of biological risk by CHWs. Conclusion: the prevalence of accidents involving biological material among CHWs is high, and the associated factors are having a university degree, having another job, and having knowledge of the vaccines required for the job. Most CHWs have a limited perception of the risk. No factors were associated with this variable.
