A segurança dos alimentos nos Centros de Tradições Gaúchas do Rio Grande do Sul / Food safety in the Centros de Tradições Gaúchas of Rio Grande do Sul

Os Centros de Tradições Gaúchas (CTG) são entidades de divulgação e perpetuação da cultura do Rio Grande do Sul. A produção de refeições nessas entidades ocorre nos ensaios dos grupos de danças tradicionais e nos eventos oferecidos à comunidade, como jantares. Sabendo do impacto das doenças transmitidas por alimentos (DTA) na saúde humana, o objetivo deste trabalho é identificar a adequação dos CTG às boas práticas para manipulação de alimentos (BPM), explorar quem são os responsáveis pelas atividades de manipulação de alimentos e identificar a frequência e o número da produção de refeições servidas nessas instituições. A Portaria SES-RS nº 78/2009 e um questionário de coleta de dados dos grupos de dança e da produção de refeições foram aplicados em 5 CTG do Rio Grande do Sul. Outros 17 CTG do estado responderam a um segundo questionário, semelhante ao primeiro, com adição de perguntas sobre controle sanitário. Obteve-se uma média de adequação às BPM de 38% entre os CTG. Verificou-se que são servidas, em média, 4 refeições por semana entre os ensaios das invernadas artísticas próximos a competições. Em 36% dos CTG, ocorrem de 2 a 3 eventos por trimestre com produção de refeições. Em 45% dos CTG, são servidas de 100 a 200 pessoas nos eventos. Em relação aos trabalhos na cozinha, apenas 23,5% dos CTG têm como responsáveis dessas atividades pessoas devidamente capacitadas. Sendo os CTG instituições sem fins lucrativos, a criação de programas para a garantia do alimento seguro nesses espaços se faz necessária.

Centros de Tradições Gaúchas (CTG) are entities for the dissemination and perpetuation of Rio Grande do Sul culture. The production of meals in these entities takes place in the rehearsals of traditional dance groups and in events offered to the community, such as dinners. Knowing the impact of the foodborne diseases in human health, the objective of this work is to identify the adequacy of CTG to good food handling practices, to explore who are responsibles for food handling activities and identify the frequency and number of meals served in these institutions. The Portaria SES-RS No. 78/2009 and a questionnaire for data collection from dance groups and meals production were applied in 5 CTG in Rio Grande do Sul. Another 17 CTG in the state answered a second questionnaire, similar to the first, with the addition of questions about sanitary control. The average compliance with good practices was 38% among the CTG. It was found that, on average, 4 meals are served per week between rehearsals of the dance groups close to competitions. In 36% of the CTG, 2 to 3 events are held per quarter with production of meals. In 45% of the CTG, the number of people served at the events varies from 100 to 200. Regarding the work in the kitchen, only 23.5% of the CTG have duly trained people for these activities. Given that CTG are non-profit institutions, the creation of programs to ensure food safety in these spaces is necessary.

Função do Ventrículo Direito e Estresse Oxidativo Melhoram com a Administração de Hormônios da Tireoide e Suco de Uva em um Modelo de Hipertensão Pulmonar / Right Ventricular Function and Oxidative Stress Improve with the Administration of Thyroid Hormones and Grape Juice in a Pulmonary Hypertension Model

Resumo Fundamento A remodelação adversa dos vasos pulmonares eleva a pressão pulmonar e provoca hipertensão arterial pulmonar (HAP). A HAP resulta em aumento da pós-carga do ventrículo direito (VD), causando hipertrofia ventricular e consequente insuficiência cardíaca. Não existe um tratamento específico para o remodelamento desadaptativo do VD secundário à HAP. Objetivos Este estudo tem como objetivo explorar duas abordagens terapêuticas, o suco de uva (SU) e os hormônios tireoidianos (HT), no tratamento do estresse oxidativo induzido pela HAP e nas alterações funcionais cardíacas. Métodos Parâmetros ecocardiográficos relacionados à resistência dos vasos pulmonares (relação TA/TE), contratilidade do VD (ESPAT) e função diastólica do VD (relação dos picos E/A) foram avaliados. Além disso, foram medidos ROS totais, peroxidação lipídica, enzimas antioxidantes, proteínas de manipulação de cálcio, expressão de proteínas pró-oxidantes e antioxidantes. Valores de p<0,05 foram considerados estatisticamente significativos. Resultados Ambos os tratamentos, com SU e HT, demonstraram uma redução na resistência pulmonar (~22%), além de melhorias na ESPAT (inotropismo ~11%) e na relação TA/TE (~26%) (p<0,05). Não houve alterações entre os grupos na relação do pico de E/A. Embora ROS e TBARS não tenham sido estatisticamente significativos, os tratamentos com SU e HT diminuíram os níveis de xantina oxidase (~49%) e normalizaram a expressão de HSP70 e proteínas de manipulação de cálcio (p<0,05). No entanto, apenas o tratamento com HT melhorou a função diastólica (~50%) e aumentou o imunoconteúdo de NRF2 (~48%) (p<0,05). Conclusões Até onde sabemos, este estudo é pioneiro ao mostrar que o HT administrado em conjunto com o SU promoveu melhorias funcionais e bioquímicas em um modelo de HAP. Além disso, nossos dados sugerem que os tratamentos com SU e HT se mostraram cardioprotetores, sejam combinados ou não, e exibiram seus benefícios ao modular o estresse oxidativo e as proteínas de manipulação do cálcio.

Abstract Background Adverse remodeling of lung vessels elevates pulmonary pressure and provokes pulmonary arterial hypertension (PAH). PAH results in increased right ventricle (RV) afterload, causing ventricular hypertrophy and the onset of heart failure. There is no specific treatment for maladaptive RV remodeling secondary to PAH. Objectives This study aims to explore two therapeutic approaches, grape juice (GJ) and thyroid hormones (TH), on PAH-induced oxidative stress and cardiac functional changes. Methods Parameters of echocardiography related to lung vessel resistance (AT/ET ratio), RV contractility (TAPSE), and RV diastolic function (E/A peaks ratio) were evaluated. Also, total ROS, lipid peroxidation, antioxidant enzymes, calcium handling proteins, pro-oxidant and antioxidant protein expression were measured. Values of p<0.05 were considered statistically significant. Results Both GJ and TH treatments demonstrated reductions in pulmonary resistance (~22%) and improvements in TAPSE (inotropism ~11%) and AT/ET ratio (~26%) (p<0.05). There were no changes amongst groups regarding the E/A peak ratio. Although ROS and TBARS were not statistically significant, GJ and TH treatments decreased xanthine oxidase (~49%) levels and normalized HSP70 and calcium handling protein expression (p<0.05). However, only TH treatment ameliorated diastolic function (~50%) and augmented NRF2 immunocontent (~48%) (p<0.05). Conclusions To the best of our knowledge, this study stands as a pioneer in showing that TH administered together with GJ promoted functional and biochemical improvements in a PAH model. Moreover, our data suggest that GJ and TH treatments were cardioprotective, combined or not, and exhibited their beneficial effects by modulating oxidative stress and calcium-handling proteins.

Comportamiento de la población chilena en las buenas prácticas de higiene

Las enfermedades transmitidas por los alimentos causan una alta carga de morbilidad, con una mayor ocurrencia en ambientes domiciliarios. El objetivo del estudio es asociar hábitos relacionados con buenas prácticas de higiene con variables sociodemográficas en una muestra representativa de la población chilena. Estudio de análisis secundario, realizado a partir de la Encuesta nacional de Salud (ENS) 2016-2017, donde se analizaron las preguntas de buenas prácticas de higiene. La muestra contempla 6.233 participantes, de los cuales el 62,8% corresponde a sexo femenino. Se identificó que las mujeres tienen mejores hábitos de higiene en la manipulación de alimentos respecto a los hombres. Por otro lado, los adultos entre 45-64 años y mayores a 65 años, presentan mejores hábitos relacionados con inocuidad alimentaria, en relación con otros grupos etarios. En conclusión, las variables sociodemográficas como sexo, edad, nivel educativo son determinantes en las buenas prácticas de higiene. Se debe educar a la población en la manipulación de alimentos, para garantizar la inocuidad alimentaria.

Foodborne diseases cause a high burden of morbidity, with a greater occurrence in home environments. The objective of the study is to associate habits related to good hygiene practices with sociodemographic variables in a representative sample of the Chilean population. Secondary analysis study, conducted from the National Health Survey (NHS) 2016-2017, where the questions of good hygiene practices were analyzed. The sample contemplates 6,233 participants, of which 62.8% corresponds to female sex. It was identified that women have better hygiene habits in food handling compared to men. On the other hand, adults aged 45-64 years and over 65 years had better habits related to food safety than other age groups. In conclusion, sociodemographic variables such as sex, age and educational level are determining factors in good hygiene practices. The population should be educated in food handling to ensure food safety.

Effect of gamete aging on fertilization success of the sea urchin Arbacia dufresnii (Arbacioida: Arbaciidae) / Efecto del envejecimiento de los gametos sobre el éxito en la fecundación del erizo de mar Arbacia dufresnii (Arbacioida: Arbaciidae)

Abstract Introduction: Short-term gametes storage is an inexpensive and simple technique that allows the use of the same batch of eggs or sperm at different times, maximizing the application of research protocols and the use of gametes in production. Arbacia dufresnii is a sea urchin species with proven aquaculture potential and already used in the nutraceutical industry. Aging of its gametes is unknown and is a needed information to scale up the production. Objective: Determine the effect of male and female gamete aging on the fertilization success of Arbacia dufresnii. This will allow optimizing the use of gametes after collection decoupling spawning from fertilization. Methods: A. dufresnii individuals were induced to spawn and gametes were kept at 12 ± 1 °C throughout each bioassay. Sperm was separated into two treatments: activated sperm in seawater (AS), and dry sperm (DS). Two bioassays were made: Bioassay 1 evaluated the effect of time on fertility by performing fertilization tests at 0 h, 24 h, 48 h, 72 h, and 96 h after spawning. Bioassay 2 evaluated the contribution of each type of aged gamete on fertility, combining aged gametes (96 h) with fresh gametes (0 h). Results: Bioassay 1: the fertilization success obtained by combining eggs (E) with AS or DS presented important differences. While the fertilization success remained acceptable (greater than 50 %) for up to 72 h using ExDS, it only remained acceptable for up to 48 h using ExAS. Bioassay 2: acceptable fertilization success was found by combining aged E (96 h) with fresh sperm, or aged DS (96 h) with fresh E, but not using aged AS with fresh E. Conclusions: The findings of this work show that fertilization success in A. dufresnii gametes remains relatively unchanged for up to 48 h after spawning when combining ExAS, and for up to 72 h when combining ExDS. However, when combining aged E or aged DS with a fresh gamete, post-collection fertilization can be extended up to 96 h. In this work, the first steps have been taken to understand the conservation time of A. dufresnii gametes with minimum intervention.

Resumen Introducción: El almacenamiento de gametos a corto plazo es una técnica económica y sencilla que permite utilizar el mismo lote de óvulos o espermatozoides en diferentes momentos, maximizando la aplicación de protocolos de investigación y el uso de gametos en la producción. Arbacia dufresnii es una especie con probado potencial acuícola como fuente de gametos para la industria nutracéutica. Sin embargo, se desconoce el envejecimiento de sus gametos y es una información necesaria para escalar la producción. Objetivo: Determinar el efecto del envejecimiento de los gametos masculinos y femeninos en el éxito de la fecundación de Arbacia dufresnii con el fin de optimizar el aprovechamiento de los gametos después de la recolecta desincronizando el desove de la fecundación. Métodos: Se indujo el desove de individuos de A. dufresnii y los gametos se mantuvieron a 12 ± 1 °C durante cada bioensayo. El esperma se separó en dos tratamientos: esperma activado en agua de mar (AS) y esperma seco (DS). Se realizaron dos bioensayos: El Bioensayo 1 evaluó el efecto del tiempo sobre la fertilidad realizando pruebas de fecundación a las 0 h, 24 h, 48 h, 72 h y 96 h después del desove. El bioensayo 2 evaluó la contribución de cada tipo de gameta envejecida (96 h) sobre la fertilidad, combinando gametos envejecidas (96 h) con gametos frescas (0 h). Resultados: Bioensayo 1: el éxito de fecundación obtenido combinando huevos (E) con AS o DS presentó diferencias importantes. Si bien el éxito de la fecundación se mantuvo aceptable (más del 50 %) durante un máximo de 72 h con ExDS, solo permaneció aceptable hasta 48 h con ExAS. Bioensayo 2: se encontró un éxito de fecundación aceptable combinando E envejecidos (96 h) con esperma fresco, o DS envejecido (96 h) con E fresco (0 h), pero no usando AS envejecido con E fresco (0 h). Conclusiones: Los hallazgos de este trabajo muestran que el éxito de la fecundación en los gametos de A. dufresnii permanece relativamente sin cambios hasta 48 h después del desove cuando se combina ExAS, y hasta 72 h cuando se combina ExDS. Sin embargo, cuando se combina E envejecido o DS envejecido con un gameto fresco, el tiempo entre la recolección y la fecundación puede extenderse hasta 96 h. En este trabajo se han dado los primeros pasos para entender el tiempo de conservación de los gametos de A. dufresnii con mínima intervención.

Longitudinal association between processed food consumption and anxiety symptoms among college students in Yunnan Province / 中国学校卫生

Objective@#To explore the association between processed food consumption and anxiety symptoms among college students in Yunnan Province, so as to provide a reference for the prevention and treatment of anxiety symptoms in this population.@*Methods@#A cluster random sample of 2 515 first year students from two universities in Yunnan Province was selected to carry out a longitudinal investigation which included a baseline survey (November 2021, T1) and three follow up visits (June 2022, T2; November 2022, T3; June 2023, T4). The food frequency questionnaire was administered to assess processed food consumption, and the Depression Anxiety Stress Scale-21 (DASS-21, Chinese version) was used to evaluate anxiety symptoms. A generalized estimation equation model was used to analyze the relationship between processed food consumption and anxiety symptoms.@*Results@#The detection rates of T1-T4 anxiety symptoms among college students in Yunnan Province were 29.70%, 36.70%, 37.69% and 38.73 %, respectively, and the corresponding anxiety symptom scores were 4(0,8), 4(0,10), 4(0,12), 2(0,14). After controlling for demographic variables and confounding factors in the generalized estimation equation model, a statistically significant association was found between consumption of carbonated beverages ( β=0.06, 95%CI =0.03-0.08), and other processed snacks ( β= 0.04 , 95%CI =0.01-0.07) ( P <0.05). The stratified analysis by gender showed that the consumption of carbonated beverages ( β=0.08, 95%CI =0.05-0.12) and fast food ( β=0.03, 95%CI =0.00-0.06) was significantly associated with anxiety symptoms in female college students ( P <0.05). There was no significant association between processed food consumption and anxiety symptoms in male college students ( P >0.05).@*Conclusions@#Processed food consumption by college students in Yunnan Province may increase the risk of anxiety symptoms, particularly among female students. There is a need to strengthen guidance in respect to processed food consumption, so as to prevent and treat anxiety symptoms.

Su cumplimiento podría prevenir consecuencias negativas en salud pública. Objetivos: Evaluar el cumplimiento de la Resolución N° 16.264/13, venta de alimentos saludables y funcionamiento de cantinas de escuelas públicas de Tobatí. Materiales y métodos: Estudio transversal en las cantinas de 11 escuelas. El instrumento fue una encuesta elaborada en base al Anexo 2 de la mencionada Resolución. Este estudio fue aprobado por el Comité de Ética en Investigación de la FCQ-UNA (Dictamen 242/16). Resultados: Los manipuladores de 8/11 cantinas, afirmaron conocer la Resolución N° 16.264/13 y la mayoría no recibió capacitación correspondiente. En 8/11 establecimientos se constataron que los pisos, paredes y techos no estaban en buen estado; 6/11 mantenían limpias las superficies de contacto con alimentos; 7/8 contaba con ventilación adecuada. En todas las cantinas un solo personal manipula alimentos y dinero en simultáneo, la mayoría de ellos no contaba con la indumentaria adecuada (cofia y delantal). En los establecimientos estudiados, se observó con mayor frecuencia que se comercializaban embutidos y snacks dulces y salados, aunque también frutas y lácteos. No existían minutas con vegetales disponibles ni las preparaciones fritas se reemplazaban por las horneadas. Conclusión: El cumplimiento de la Resolución N° 16.264/13 en la mayoría de estas cantinas escolares fue bajo y en ellas predominó la venta de alimentos con alto contenido energético y escaso valor nutritivo.

Introduction: The Resolution No. 16,264/13 of the Ministry of Education and Science (MEC) regulates the procedure and monitoring of school canteens in Paraguay. Its compliance could prevent negative consequences on public health. Objectives: Evaluate compliance to Resolution No. 16,264/13, sale of healthy food and operation of canteens in public schools in Tobatí. Materials and methods: A Cross-sectional study in 11 schools´ canteens. The questionaire was a survey based on Annex 2 of the Resolution and was approved by the FCQ-UNA Research Ethics Committee (242/16). Results: The food handlers of 8/11 canteens stated that they were familiar with Resolution No. 16.264/13 and most of them received the corresponding training. In 8/11 establishments it was found that floors, walls, and ceilings were not in good condition; 6/11 kept food contact surfaces clean; 7/8 had adequate ventilation. In all the canteens, only one staff handled food and money at the same time, most of them did not have the appropriate clothing (cap and apron). Most of the establishments sold sausages and sweet and salty snacks, where fruits and dairy products were also sold, and no vegetable meal menus available, nor were fried foods replaced by baked foods. Conclusion: compliance to Resolution No. 16,264/13 in most of these school canteens was low and the sale of food with high energy content and low nutritional value predominated.

All this is carried out in strict compliance with the dose limits established for the zone, the occupation times, the control points and the corresponding measurement equipment. The proposed methodology is designed to address the practical needs of radiometabolic therapy centers in their daily operation, considering real exposure conditions. The results confirm the suitability of the shielding systems, specifically adapted to the activities carried out in these installations

Control microbiológico de alimentos en la vía pública en Cuenca, Ecuador

El comercio ambulante de alimentos listos para el consumo ha crecido exponencialmente a nivel mundial. Sin embargo, la falta de condiciones óptimas de preparación y expendio de estos alimentos pueden afectar su inocuidad. El objetivo de este estudio fue evaluar la calidad microbiológica de 19 tipos de alimentos (n= 417), con y sin tratamiento térmico, expendidos en espacios públicos en Cuenca, Ecuador. Según el grupo de alimentos, se analizaron aerobios mesófilos, coliformes/Escherichia coli, mohos y levaduras, Staphylococcus aureus, Salmonella, Listeria spp., Clostridium perfringes y Vibrio parahaemolyticus. Para la identificación y recuento de los microorganismos se aplicaron normativas nacionales y, en casos de ausencia, se adoptaron normas de otros países. Como resultado, el 55,4% de las muestras se consideraron no aptas para el consumo. S. aureus fue el microorganismo patógeno presuntivo de mayor prevalencia (81,7%). El incumplimiento de las normativas fue significativamente mayor entre los alimentos sin tratamiento térmico (54,1%) en comparación con aquellos térmicamente tratados (24%) y los que combinan ingredientes con y sin tratamiento (21,9%) (p<0,001). Se destaca el alto porcentaje de incumplimiento de alimentos sin tratamiento térmico que son manipulados en su preparación, como los jugos. Además, se observó que el tratamiento térmico no garantizó la inocuidad, sugiriendo una posible recontaminación del alimento luego de su preparación hasta su expendio y consumo, por medios ambientales y/o adición de otros ingredientes contaminados. Este estudio recalca la necesidad de acciones concretas con este sector, basados principalmente en capacitación, infraestructura e inclusión, para garantizar la salud de los consumidores.

Street-vending trade in ready-to-eat foods has grown exponentially, worldwide. However, the lack of optimal conditions for the preparation and sale of these foods can affect their safety. The objective of this study was to evaluate the microbiological quality of 19 types of foods (n= 417), with and without heat treatment, sold in public spaces in Cuenca, Ecuador. According to the food group, mesophilic aerobes, coliforms/Escherichia coli, molds and yeasts, Staphylococcus aureus, Salmonella, Listeria spp., Clostridium perfringens, and Vibrio parahaemolyticus were examined. For microorganisms identification and counting, national regulations were applied and, in cases of absence, regulations from other countries were adopted. As a result, 55,4% of the samples were considered inadequate for consumption. S. aureus was the most prevalent presumptive pathogenic microorganism (81.7%). Non-compliance with regulations was significantly higher among foods without heat treatment (54.1%) compared to those heat treated (24%) and those that combine ingredients with and without treatment (21.9%) (p<0.001). The high percentage of non-compliance with foods without heat treatment that is handled for preparation, such as juices, stands out. In addition, it was observed that the heat treatment did not guarantee safety, suggesting possible food recontamination after preparation until sale and consumption, due to environmental means and/or the addition of other contaminated ingredients. This study emphasizes the need for concrete actions in this sector, mainly based on training, infrastructure, and inclusion, to guarantee consumers' health.

Use of Schirmer strips and conjunctival swabs for virus detection on the ocular surface of adults: a scoping review / Fitas de Schirmer e swab conjunctival para detecção de vírus na superfície ocular de adultos: scoping review

ABSTRACT Schirmer strips and conjunctival swabs are used in ophthalmology for the collection of tears and fluids. One of the biggest challenges during the COVID-19 pandemic has been accurate diagnosis and, in some cases, ocular manifestations are among the first symptoms. In this context, this study aimed to collect evidence to support the use of Schirmer strips and conjunctival swabs as a method of sample collection for viral analysis. A literature search was conducted following the Scoping Review protocol defined by The Joanna Briggs Institute. Studies were analyzed regarding virus research, collection methods, and sample analysis. The findings support that viruses can be detected on the ocular surface through analysis of Schirmer strips and conjunctival swabs. However, additional studies with larger samples and time data are necessary to confirm these conclusions.

RESUMO A fita de Schirmer e o swab conjunctival são utilizados na oftalmologia como métodos de coleta para lágrimas e fluidos. Durante a pandemia da COVID-19, um dos desafios foi o diagnóstico correto e se sabe que, em alguns casos, as manifestações oculares podem ser um dos primeiros sintomas. Nesse contexto, este estudo tem como objetivo levantar evidência que destaque o uso de fitas de Schirmer e de swabs conjuntivais como método de coleta para análise viral. Conduziu-se uma revisão de literatura seguindo o protocolo para Scoping Review definido pelo Joanna Briggs Institute. Os pesquisadores analisaram os estudos em busca do vírus pesquisado, os métodos de coleta e os métodos de análise. Vírus podem ser detectados na superfície ocular através da análise de fitas de Schirmer e de swabs conjuntivais, entretanto novos estudos com populações maiores e com definições claras de tempo são necessários para conclusões mais assertivas no tema.

Citopatológico do colo uterino e adequabilidade da amostra: ensaio clínico randomizado controlado / Cervical cytopathology and sample suitability: a randomized controlled clinical trial

Resumo Objetivo Avaliar duas técnicas de coleta cervicovaginal à adequabilidade da amostra e aos demais achados do laudo colpocitopatológico. Métodos O estudo foi realizado no período de setembro de 2018 a julho de 2019, em um centro de saúde-escola, localizado no município de Fortaleza - Ceará. A amostra foi composta por 365 mulheres divididas aleatoriamente, sendo 184 participantes no Grupo Controle (técnica na qual o esfregaço da ectocérvice foi disposto na lâmina antes da coleta do material da endocérvice) e 181 no Grupo Comparação (no qual o esfregaço da ectocérvice vaginal foi disposto na lâmina apenas após a coleta do material da endocérvice). Utilizou-se um instrumento contendo variáveis sociodemográficas, clínicas, sexuais, reprodutivas e referentes aos achados no laudo citopatológico. Incluíram-se mulheres na faixa etária de 18 a 64 anos, que já tinham iniciado vida sexual e que realizaram o exame de prevenção do câncer de colo uterino no período da coleta de dados. Os testes do qui-quadrado, Fisher e Kruskal-Wallis foram utilizados. Resultados Não houve associação estatística entre a adequabilidade da amostra citopatológica às duas técnicas de coleta cervicovaginal empregadas e às demais variáveis clínicas, sexuais, reprodutivas e referentes aos demais achados no laudo citopatológico, obtendo-se valor de p>5% em todas as associações realizadas.

Resumen Objetivo Evaluar dos técnicas de toma de muestra cervicovaginal con la adecuación de la muestra y con los demás resultados del informe colpocitológico. Métodos El estudio fue realizado durante el período de septiembre de 2018 a julio de 2019, en un centro de salud-escuela, ubicado en el municipio de Fortaleza, estado de Ceará. La muestra estaba compuesta por 365 mujeres divididas aleatoriamente, de las cuales 184 participantes estaban en el Grupo Control (técnica por la que el frotis del ectocérvix fue colocado en la lámina antes de la toma del material del endocérvix) y 181 en el Grupo Comparación (en el que el frotis del ectocérvix vaginal fue colocado sobre la lámina únicamente después de la toma del material del endocérvix). Se utilizó un instrumento con variables sociodemográficas, clínicas, sexuales, reproductivas y relativas a los resultados del informe citológico. Fueron incluidas mujeres del grupo de edad de 18 a 64 años, que ya habían empezado su vida sexual y que realizaron la prueba de prevención de cáncer de cuello uterino durante el período de la recopilación de datos. Se utilizaron las pruebas χ2 de Pearson, Fisher y Kruskal-Wallis. Resultados No hubo asociación estadística entre la adecuación de la muestra citológica con las dos técnicas de toma cervicovaginal utilizadas y con las demás variables clínicas, sexuales, reproductivas y referentes a los demás resultados del informe citológico, y se obtuvo un valor de p>5 % en todas las asociaciones realizadas. Conclusión Las dos técnicas de toma de células cervicales que se describen en manuales oficiales no difirieron en la obtención de una muestra celular adecuada y son igualmente eficaces y favorecen la garantía de un informe colpocitológico preciso y oportuno.

Abstract Objective To assess two cervicovaginal collection techniques to sample suitability and the other findings of Pap smear. Methods The study was conducted from September 2018 to July 2019, in a school health center located in the city of Fortaleza - Ceará. The sample consisted of 365 women randomly divided, with 184 participants in the Control Group (technique in which the ectocervix smear was placed on the slide before endocervical material was collected) and 181 in the Comparison Group (in which the vaginal ectocervix smear was placed on the slide only after collecting the material from the endocervix). An instrument containing sociodemographic, clinical, sexual, reproductive and findings in cytopathological report was used. Women aged between 18 and 64 years, who had already started their sexual life and who underwent the cervical cancer prevention test during the data collection period, were included. Chi-square, Fisher and Kruskal-Wallis tests were used. Results There was no statistical association between cytopathological sample suitability for the two cervicovaginal collection techniques used and for the other clinical, sexual, reproductive and other variables related to the other findings in cytopathological report, obtaining a value of p>5% in all associations performed. Conclusion The two techniques for collecting cervical cells described in official manuals did not differ for obtaining an adequate cell sample, being equally effective and providing the guarantee of an accurate and timely Pap smear.

8. Introduction of Consideration for Students at University of Tsukuba / 医学教育

The University of Tsukuba aims to be a university where all members, not only LGBT but also everyone with diverse personalities, can share their abilities. The Bureau of Human Empowerment plays a central role in student support in line with the Basic Principles and Guidelines on LGBT+ Inclusion at the University of Tsukuba (2020 revision). Students' gender information is accessible only to those who need it, such as teachers in charge. Faculty and staff are encouraged to handle information carefully. While basic knowledge of LGBT and others is necessary, it is also important to consider all students based on the premise that there are those with diverse personalities who are not LGBT, rather than treating LGBT and other students specially. We shared our opinions with faculty and the faculty development (FD) committee members at FD meetings.

Optimization and simulation of maneuverability and stability of electric wheelchair based on three degrees of freedom model / 中国康复理论与实践

ObjectiveTo propose a three-degree-of-freedom model of electric wheelchair, to optimize the steering stability of the wheelchair. MethodsBased on the two degrees of freedom vehicle model and considering the influence of body inertia and lateral wind, the wheelchair roll angle was introduced to establish the three degrees of freedom steering model of wheelchair. The lateral velocity, centroid sideslip angle, yaw rate and body roll angle response of the motor angular velocity input under different working conditions were simulated and analyzed respectively. Taking KS2 electric wheelchair as an example, the wheelchair steering experiment was designed to verify the rationality and feasibility of the model, and the optimization effect of the model algorithm on the wheelchair handling and stability. ResultsThe maneuverability and stability of the electric wheelchair with three degrees of freedom model algorithm were significantly improved, and the response curve was smoother. The smaller the |VL-VR|/t was, the better the handling stability was when the left and right motors of the wheelchair had the same steering direction. When |VL-VR|/t was the same, the steering maneuverability was better on the reverse rotation of the motor, but the handling stability also decreased. ConclusionThe simulation analysis is in good agreement with the experimental results, which verifies that the model is reasonable and feasible. The model algorithm can better optimize the handling stability of electric wheelchairs, and can be generally applied to study and analyze the handling stability of different wheelchairs when they turn.

Características microscópicas del cérvix uterino mediante citología líquida

Introducción: La citología líquida es un método que puede contribuir a identificar de manera precoz los cambios microscópicos del cérvix uterino que pudieran progresar a la malignidad, al disminuir el número de muestras insatisfactorias en relación a la citología convencional. Objetivo: Analizar las características microscópicas identificadas mediante la citología de base líquida del cérvix uterino en mujeres atendidas en la Unidad de Bienestar Estudiantil de la Universidad Técnica de Manabí, Ecuador. Métodos : Se realizó un estudio de serie de casos donde se analizaron las características sociodemográficas, microbiológicas e histológicas procedentes de las fichas médicas de 132 mujeres que participaron en la campaña de Papanicolaou realizado durante junio de 2019. Resultados: El rango de edad predominante fue el de 19 a 33 años, residían en área urbana, 64 % de las mujeres inició la vida sexual antes o durante sus 18 años. Los hallazgos microbiológicos mostraron presencia de flora cocoide en 50 % y 100 % de las muestras manifestaron la calidad adecuada. El estudio citológico presentó, según el sistema Bethesda, 75 % de muestras negativas, con 13 % de LIE de bajo grado y 11 % de ASCUS. El fondo del frotis inflamatorio leve se presentó en 52 %, mientras los antecedentes de más de tres citologías anteriores positivas resultaron en 34 % de las féminas. No se encontró relación entre la presencia de lesión intraepitelial y la edad de las pacientes (p=0,3076). Conclusiones: El total de las muestras fueron útiles lo cual puede indicar que la citología de base líquida ofrece una mayor calidad del diagnóstico histológico.

Introduction: Liquid-based cytology is a method that can contribute to the early identification of microscopic changes in the uterine cervix that can progress to malignancy, by reducing the number of unsatisfactory samples compared to conventional cytology. Objective: To analyze the microscopic characteristics identified by liquid-based cytology of the uterine cervix in women treated at the Student Welfare Unit of the Technical University of Manabí, Ecuador. Methods: A descriptive, cross-sectional, retrospective and quantitative study was carried out where the sociodemographic, microbiological and histological characteristics collected in the medical records of 132 women who participated in the Pap smear campaign carried out during June 2019 were analyzed. Results: The age range that prevailed was 19 to 33 years who lived in urban areas, 64% of women began their sexual life before or at 18 years of age. The microbiological findings showed the presence of coccoid flora in 50% and 100% of the samples showed adequate quality. The cytological study presented, according to the Bethesda system, 75% of negative samples, with 13% low-grade IEL and 11% ASCUS. The background of the mild inflammatory smears was present in 52%, the history of previous positive cytology in 34% was more than three. All of the samples were useful. No relationship was found between the presence of intraepithelial lesion and the age of the patients (p=0.3076). Conclusions: CBL can ensure a higher quality of histological diagnosis by guaranteeing a greater number of useful samples.

Condições higiênicossanitárias de unidades de alimentação e nutrição de escolas participantes do Programa Nacional de Alimentação Escolar: qual a realidade em Goiás? / Hygienic and sanitary conditions of "Units of food and nutrition" at schools participating in the Brazilian School Feeding Program: What is the reality in Goiás?

Introdução: Para a oferta de refeições seguras aos estudantes, preconizado pelo Programa Nacional de Alimentação Escolar, se faz necessária uma condição higiênicossanitária adequada da Unidade de Alimentação e Nutrição. Objetivo: Avaliar as condições higiênicossanitárias das Unidades de Alimentação e Nutrição de escolas participantes do Programa Nacional de Alimentação Escolar em municípios goianos, bem como verificar possíveis associações com: índices municipais, características da escola e supervisão de nutricionista. Método: Estudo transversal, realizado entre 2017 e 2019, com amostra de 395 escolas, de 103 municípios de Goiás. As condições higiênicossanitárias foram verificadas por nutricionistas, por meio de um checklist baseado na RDC nº 216, de 15 de setembro de 2004 da Agência Nacional de Vigilância Sanitária e nos índices municipais de desenvolvimento humano e da educação básica em base de dados públicas. As características da escola e o recebimento de supervisão foram perguntados aos diretores escolares. Realizou-se uma análise descritiva dos itens do checklist e testes de hipóteses e correlação. Resultados: A maioria das unidades (69,4%) foi classificada como de risco sanitário regular, de acordo com o checklist. Obteve-se diferenças significativas entre: as escolas municipais e estaduais (p = 0,02); a mesorregião Norte das outras (p = 0,00) e o baixo Índice de Desenvolvimento Humano das demais categorias (p = 0,02). Ademais, o alto Índice de Desenvolvimento da Educação Básica (5º ano) apresentou uma associação com o muito baixo risco sanitário (p = 0,04). Conclusões: Infere-se que há necessidade de medidas corretivas. Sugere-se a implementação de manuais de boas práticas; a formação de manipuladores; a supervisão contínua do nutricionista e do Conselho de Alimentação Escolar; e o investimento da gestão com vistas à Segurança Alimentar e Nutricional dos escolares.

Introduction: In order to offer safe meals to students, recommended by the Brazilian School Feeding Program (PNAE, in Portuguese), an adequate hygienic-sanitary condition of "Units of Food and Nutrition" is necessary. Objective: To evaluate the hygienic-sanitary conditions of the "Units of Food and Nutrition" at schools participating in the Brazilian School Feeding Program in municipalities in Goiás, as well as to verify possible associations with municipal indexes, school characteristics and supervision by a nutritionist. Method: Cross-sectional study, carried out between 2017 and 2019, with a sample of 395 schools, from 103 municipalities in Goiás. The hygienic-sanitary conditions were collected by nutritionists, through a checklist based on Anvisa's RDC nº 216/2004 and municipal indexes of human development and basic education in public databases. The school's characteristics and the existence of supervision by a nutritionist were asked to school directors. Descriptive analysis of the checklist items and hypothesis and correlation tests were performed. Results: Most units (69.4%) were classified as having regular health risk, according to the checklist. Significant differences were obtained between municipal and state schools (p = 0.02); difference of northern mesoregion from the others (p = 0.00) and low Human Development Index of the other categories (p = 0.02) were observed. Furthermore, the high Basic Education Development Index (5th grade) was associated with a very low health risk (p = 0.04). Conclusions: It is inferred that there is a need for corrective measures. Manuals of good practices should be implemented, along with training of handlers, ongoing supervision by the nutritionist and the School Feeding Council, and investment in management with a view to the Food and Nutritional Security of schoolchildren.

Food handling in the domestic environment: an online questionnaire study with respondents from 24 of 26 Brazilian states / Manipulação de alimentos no ambiente doméstico: um estudo realizado com emprego de questionário online respondido por habitantes de 24 dos 26 estados brasileiros

Using an online questionnaire, this study evaluated the profile of a Brazilian population's food handling practices in the home environment. The questionnaire, containing questions about domestic behavior in terms of hygiene and food handling, was built and available through social media sites. Information about the participants' profiles, their food pre-preparation, food preparation, and food post-preparation practices, and the occurrence of foodborne diseases (FBDs) was included in the questionnaire. A total of 701 responses were obtained. The interviewees included 78.31% female participants and 21.68% male participants, with an average age of 31.2 years. Nearly all (94.3%) had a complete or incomplete higher education. In the pre-preparation stage, the participants evaluated the shelf life (97.28%) and storage temperature (44.79%) of the products while purchasing them. Regarding food handling practices, only a few participants washed the food packages before storing them (31.95%) or removed hand jewelry or other adornments when washing food (61.48%). Most participants washed their hands (91.58%) and washed vegetables (99.28%). But a group of interviewees reported washing raw meat (27.81%) before preparing it. Cutting surfaces such as plastic (50.36%) and glass (49.36%) tops were the most prevalent in the study. Most respondents did not know how long they had been using their cutting boards (67.62%) and mentioned using the same surface to handle both raw and ready-to-eat products (84.17%). As for the preparation, most interviewees declared they did not check the food temperature during preparation (86.31%), ignoring the ideal cooking temperature (88.26%). Regarding the occurrence of FBDs, 79.17% of the interviewees reported having suspicious clinical signs associated with contaminated foods and 65.59% did not seek medical help. Thus, the participants demonstrated ignorance about adequate practices for food safety in the home environment, highlighting the need to conduct health education programs within the Brazilian population.(AU)

Este estudo teve como objetivo avaliar o perfil das práticas de manipulação de alimentos no ambiente domiciliar no Brasil utilizando um questionário online. Um questionário contendo perguntas sobre comportamento doméstico em nível de higiene e manipulação de alimentos foi construído e disponibilizado por redes sociais. O questionário continha informações sobre o perfil dos participantes, suas práticas de pré-preparo, preparo e pós-preparo de alimentos e a ocorrência de doenças transmitidas por alimentos (DTA). Obteve-se 701 respostas, os entrevistados foram 78,31% do sexo feminino e 21,68% do sexo masculino, com média de idade de 31,2 anos. A maioria (94,3%) possuia ensino superior completo ou incompleto. Na etapa de pré-preparo, os participantes avaliam o prazo de validade (97,28%) e a temperatura de armazenamento (44,79%) dos produtos no momento da compra. Em relação às práticas de manipulação dos alimentos, apenas alguns participantes lavavam as embalagens dos alimentos antes de armazená-los (31,95%) ou retiravam adornos ao lavar os alimentos (61,48%). A maioria dos participantes lavam as mãos (91,58%) e os vegetais (99,28%); entretanto, um grupo de entrevistados relatou lavar carne crua (27,81%) antes de prepará-la. Superfícies de corte como tábuas de plástico (50,36%) e de vidro (49,36%) foram os mais prevalentes no estudo. A maioria dos entrevistados não sabe há quanto tempo usa as tábuas de corte (67,62%) e utilizam a mesma superfície para manusear produtos crus e prontos para o consumo (84,17%). Quanto ao preparo, a maioria dos entrevistados declarou não verificar a temperatura dos alimentos durante o preparo (86,31%), ignorando a temperatura ideal de cozimento (88,26%). Em relação à ocorrência de DVA, 79,17% dos entrevistados relataram que já apresentaram sinais clínicos suspeitos associados a alimentos contaminados e 65,59% não procuraram atendimento médico. Nesse sentido, os participantes demonstraram desconhecimento sobre as práticas adequadas para a segurança dos alimentos no ambiente domiciliar, evidenciando a necessidade de realização de programas de educação em saúde com a população brasileira.(AU)
