Influence of acute heat shock on antioxidant defense of tropical fish, Psalidodon bifasciatus.

Psalidodon bifasciatus is a fish species sensitive to physical and chemical changes in water. It serves as a good bioindicator of temperature variations and is utilized in environmental monitoring studies in Brazilian rivers. The objective of this study was to evaluate antioxidant defense biomarkers in the heart, brain, and muscle of P. bifasciatus exposed to a 10 °C thermal increase. P. bifasciatus were collected and divided into a control group (21 °C) and groups subjected to thermal shock (31 °C) for periods of 2, 6, 12, 24, and 48h. Two-way ANOVA indicated that a 10 °C temperature increase caused oxidative stress in P. bifasciatus. This was evidenced by altered levels of lipid peroxidation (LPO), carbonylated proteins (PCO), and glutathione peroxidase (GPx) in the heart, catalase (CAT) and LPO in the brain, and LPO in the muscle. Principal component analysis (PCA) and integrated biomarker response (IBR) analysis indicated that, compared to the heart and muscle, the brain exhibited a greater activation of the antioxidant response. Sensitivity analysis indicated that the muscle was the most sensitive organ, followed by the brain and heart. Our results indicate that the stress response is tissue-specific through the activation of distinct mechanisms. These responses may be associated with the tissue's function as well as its energy demand. As expected, P. bifasciatus showed changes in response to thermal stress, with the brain showing the greatest alteration in antioxidant defenses and the muscle being the most sensitive tissue.

Physiological strategies of acute thermal conditions of Rhamdia voulezi collected in the Iguaçu river watershed, Paraná, Brazil: biochemical markers of metabolic and oxidative stress.

Thermal pollution creates substantial challenges that alter energy demand and produce reactive oxygen species that damage fish DNA, proteins, and lipids. Rhamdia voulezi is a species of fish native to the Iguaçu river, Paraná, Brazil, that does not have scientific records of minimum (CTmin) and maximum (CTmax) temperatures required for survival. As it is a top predator species in the food chain and lives at temperatures below 22 °C, the loss of the species can cause functional problems in controlling the ecosystem and energy flow. The study evaluated the tissue metabolism of the brain, heart, and muscle of R. voulezi (n = 72) subjected to acute thermal stress of 31 °C for 2, 6, 12, 24, and 96 h after acclimatization to 21 °C. The biochemical markers SOD, GPx, MDH, HK, and CK of the brain, PCO of the heart and CAT, glycogen, G6PDH, and ALT of muscle were significant. PCA, IBR, thermal sensitive, and condition factor suggested that R. voulezi has different physiological strategies for acclimatization to 31 °C to mobilize and sustain the metabolic needs of oxygenation and energy allocation/utilization for tissue ATP production.

Impact of SumiLarv® 2MR on Aedes aegypti larvae: a multicenter study in Brazil.

BACKGROUND: Aedes aegypti is associated with dengue, Zika, and chikungunya transmission. These arboviruses are responsible for national outbreaks with severe public health implications. Vector control is one of the tools used to prevent mosquito proliferation, and SumiLarv® 2MR is an alternative commercial product based on pyriproxyfen for larval/pupal control. In this study, the residual effectiveness of SumiLarv® 2MR in different regions of Brazil was evaluated in simulated field conditions. METHODS: We conducted a multicenter study across four Brazilian states-Amapá, Pernambuco, Rio de Janeiro, and São Paulo-given the importance to the country's climatic variances in the north, northeast, and southeast regions and their influence on product efficiency. The populations of Ae. aegypti from each location were held in an insectary. Third-instar larvae (L3) were added every 2 weeks to water containers with SumiLarv® 2MR discs in 250-, 500- and 1000-l containers in Amapá and Rio de Janeiro, and 100-l containers in Pernambuco and São Paulo, using concentrations of 0.04, 0.08, and 0.16 mg/l. RESULTS: Adult emergence inhibition over 420 days was observed in all tests conducted at a concentration of 0.16 mg/l; inhibition for 308-420 days was observed for 0.08 mg/l, and 224-420 days for 0.04 mg/l. CONCLUSIONS: Sumilarv® 2MR residual activity demonstrated in this study suggests that this new pyriproxyfen formulation is a promising alternative for Aedes control, regardless of climatic variations and ideal concentration, since the SumiLarv® 2MR showed adult emergence inhibition of over 80% and residual activity greater than 6 months, a period longer than that recommended by the Ministry of Health of Brazil between product re-application in larval breeding sites.

Assessing physiological responses and oxidative stress effects in Rhamdia voulezi exposed to high temperatures.

Exposure to high temperatures induces changes in fish respiration, resulting in an increased production of reactive oxygen species. This, in turn, affects the enzymatic and non-enzymatic components of antioxidant defenses, which are essential for mitigating cellular stress. Rhamdia voulezi, an economically important fish species endemic to Brazil's Iguaçu River, served as the subject of our study. Our goal was to assess enzymatic antioxidant biomarkers (superoxide dismutase, catalase, glutathione peroxidase, glutathione S-transferase, glutathione reductase, glucose-6-phosphate dehydrogenase), non-protein thiol levels (reduced glutathione), and markers of oxidative damage (lipoperoxidation and carbonylation) in the liver, gills, and kidneys of R. voulezi after acute exposure to high temperatures (31°C) for 2, 6, 12, 24, and 96 h. Control groups were maintained at 21°C. Our findings revealed that the liver exhibited increased superoxide dismutase levels up to 12 h and elevated glutathione S-transferase levels at 12 and 96 h at 31°C. In the gills, superoxide dismutase levels increased up to 24 h, along with increased lipoperoxidation at 2, 6, 12, and 96 h of exposure to high temperatures. The kidneys responded to heat stress at 12 h, with an increase in superoxide dismutase and catalase activity, and lipid peroxidation was observed at 2 and 6 h at 31°C. The three tissues evaluated responded differently to heat stress, with the liver demonstrating greater physiological adjustment to high temperatures. The intricate interplay of various antioxidant defense biomarkers and oxidative damage suggests the presence of oxidative stress in R. voulezi when exposed to high temperatures.

Social networking website increases efficacy and engagement in a distance learning course about oral lesions.

PURPOSE: Distance learning appears to be an attractive approach to continuing education courses, but one barrier is maintaining learner engagement throughout the course. The primary aim of this research was to evaluate the operational efficacy of a private Facebook™ group (FG) in serving as a support mechanism for distance learning courses, and its impact on three fundamental dimensions: the attrition rates of participants who did not complete the course (commonly referred to as dropout rates), the rates of course completion and approval, and the overall performance of the participants. METHODS: The participants of this quasi-experimental study comprised 159 dental students and 565 dentists enrolled in an e-learning course on oral mucosal lesion diagnosis. Prior to the initiation of the course, all participants were provided with the option to join a private FG. Within this group, moderators shared motivational messages and provided reminders concerning deadlines. Moreover, participants had the opportunity to engage in interactive discussions pertaining to topics related to the course. The course itself followed a self-guided format, employing the flipped-classroom methodology, spanning a total of 50 instructional hours. In order to assess the effectiveness of the course, participants were presented with photographs illustrating 30 oral lesions and were asked to propose diagnostic hypotheses both before and after the educational intervention (pre-tests and post-tests). RESULTS: Dentists who participated in the FG exhibited a significantly lower rate of discontinuation. As for dental students, their involvement in the group was positively associated with better performance, as determined by the percentage of accurate diagnostic hypotheses (a minimum of 70% correct responses was required for their approval in the course). CONCLUSIONS: Facebook™ demonstrates promise as a supplementary pedagogical tool in distance education courses. The interactive nature of the platform has the potential to alleviate the inherent challenges of remote learning.

Influência dos indicadores socioeconômicos na distribuição dos casos suspeitos de dengue no município de São Carlos-SP / Influence of socioeconomic indicators on the distribution of suspected dengue

Resumo O estabelecimento definitivo do Aedes aegypti nas Américas está associado às mudanças ambientais, urbanização desorganizada, ausência de água e saneamento básico e deslocamentos populacionais, definindo, assim, a trajetória da doença. O objetivo deste estudo foi analisar a distribuição espacial dos casos suspeitos de dengue e a relação com indicadores socioeconômicos no município de São Carlos-SP. Trata-se de estudo ecológico, realizado nesse município, em que foram utilizados dados secundários do Sistema de Informação sobre Agravos de Notificação no período de 2016 a 2017 e do Instituto Brasileiro de Geografia e Estatística do Censo Demográfico de 2010. Os dados foram analisados por meio da Análise de Componentes Principais pelo software Statistica 12.0 e os mapas temáticos foram gerados pelo software Arcgis versão 10.5. Os resultados mostraram elevadas taxas de casos suspeitos de dengue em áreas de ponderação com condições sociais adequadas e taxas reduzidas em áreas de ponderação com iniquidades sociais. Concluiu-se que o perfil de casos suspeitos por dengue na população de São Carlos não está relacionado a baixos indicadores socioeconômicos, uma vez que a dinâmica e a mobilidade populacional relacionadas ao elevado fluxo de universitários podem influenciar no padrão de distribuição espacial da doença.

Abstract The definitive establishment of Aedes aegypti in the Americas is associated with environmental changes, disorganized urbanization, lack of water and basic sanitation and population displacement, thus defining the trajectory of the disease. The aim of this study was to analyze the spatial distribution of the dengue suspected cases and understand its correlation with the socioeconomic indicators in the city of São Carlos (SP). This is an ecological study, carried out at the São Carlos (SP). Secondary data from the Information System on Notifiable Diseases in the period from 2016 to 2017 and from the Brazilian Institute of Geography and Statistics of the 2010 Demographic Census were used. The data were analyzed using Principal Component Analysis (ACP) by the software Statistica 12.0 and the thematic maps were generated by the software Arcgis version 10.5. The results showed high rates of suspected dengue cases in areas with adequate social conditions and reduced rates in areas with worst social condition. It was concluded that the outline of suspected dengue cases in the population of São Carlos (SP) is not related to low socioeconomic indicators, once the population dynamics and mobility related to the high flow of university students can influence the pattern of spatial distribution of the disease.

Evaluation of Long-lasting insecticidal nets (LLINs) for malaria control in an endemic area in Brazil.

BACKGROUND: Most cases of malaria in Brazil are concentrated in the Amazon region. One of the vector control alternatives recommended by the WHO is the long-lasting insecticidal net (LLIN). This tool is used in the nine federal states of the Brazilian Legal Amazon, where LLINs are essential for reducing vector density and disease transmission as they prevent contact between the mosquito and the individual. The objective of this study was to evaluate the residuality and use of LLIN insecticides in different health regions in a city located in the Brazilian Amazon. METHODS: A total of 17,027 LLINs were installed in the third, fifth and ninth health regions of the municipality of Porto Velho, Rondonia State, Brazil. The LLINs were of two types: Olyset (permethrin), for around the bed, and Interceptor (alphacypermethrin), for around hammocks. The residuality of 172 LLINs was evaluated using cone bioassays to verify the mortality rate of the mosquito Nyssorhynchus darlingi, over a period of 2 years. Structured questionnaires on the acceptance and use of LLINs were distributed to the participating population (n = 391), covering a total sample of 1147 mosquito nets. The mortality rate was evaluated both in terms of days after LLIN installation and the type of insecticide used. Statistical analyses were based on analysis of variance (ANOVA) and Chi-square and were performed using the SPSS statistical program. RESULTS: For the Ny. darlingi mosquito, Interceptor-type LLINs showed residual efficacy, with mortality rates ≥ 80% during the 2-year study period, as determined by the WHO. In contrast, Olyset-type LLINs were associated with a reduction in mortality rates, with 76% and 45% mortality rates in the last two assessments, which occurred during the last 6 months of the study period. Based on the structured questionnaires, the acceptance rate, i.e. percentage of individuals accepting the permanence of the 1147 LLINs sampled, in the three health regions of Porto Velho was 93.8% (of 1076 LLINs). CONCLUSION: The alphacypermethrin-impregnated LLIN was more effective than the LLIN impregnated with permethrin. The results indicate that the correct use of mosquito nets-and consequently the protection of the population-needs to be supported by health promotion actions. These initiatives are considered to be essential for the success of this vector control strategy. New studies that consider the monitoring of the placement of mosquito nets are necessary to provide effective support in the correct use of this methodology.

Raça/cor da pele e morbimortalidade por COVID-19 no estado de São Paulo - SP / Race/skin color and covid-19 morbidity and mortality in the state of São Paulo ­ SP / Raza/color de piel y morbimortalidad por covid-19 en el estado de São Paulo - SP

Objetivo: analisar a relação entre a raça/cor da pele e a morbimortalidade por COVID-19 no estado de São Paulo-SP. Métodos: Estudo ecológico, retrospectivo e analítico, cujos dados foram coletados no Sistema Estadual de Análise de Dados (SEADE) do Governo do Estado de São Paulo e correspondem ao período de fevereiro de 2020 a setembro de 2021. Na análise de dados, utilizou-se o modelo de regressão com distribuição binomial-negativa múltipla, para comparar a incidência e a mortalidade específica entre as raças/cores de pele. Resultados: ao se compararem as curvas de incidência de COVID-19, houve diferença estatística significativa entre as comparações de todos os grupos de raça/cor da pele. Na comparação entre tendências branca vs parda, o resultado foi p = 0,007; na comparação entre tendências branca vs preta, p = <0,001; na comparação entre tendências parda vs preta, p = 0,003. Porém, quando foram comparadas as tendências de incidência por sexo e faixa etária e as tendências de óbito, não houve diferença estatística. Conclusão: a raça/cor da pele influenciou nas curvas de incidência geral por COVID-19 no estado de São Paulo, porém a não associação com a mortalidade pode estar relacionada com a falta de informação sobre raça/cor/etnia nas fichas de notificação, afetando consequentemente sua disponibilidade nos sistemas de informação, o que reforça a importância da divulgação de dados epidemiológicos oficiais de qualidade.(AU)

Objective: to analyze the relationship between ethnicity/skin color and morbi-mortality from COVID-19 in the state of São Paulo-SP. Methods: ecological, retrospective, and analytical study, whose data were collected from the State Data Analysis System (SE-ADE) of the Government of the State of São Paulo, covering from February 2020 to September 2021. Data analysis used a regression model with multiple binomial negative distribution, to compare the incidence and mortality specific between ethnicities/skin colors. Results: a comparison between the incidence curves of COVID-19 showed a signi-ficant statistical difference between all groups of ethnicity/skin color. In the comparison of trends between white and brown, the result was p = 0.007; in the comparison of trends between white and black, it was p = 0.001; in the comparison of trends between brown and black, p = 0.003. However, when we compare the trends of incidence per sex and age group with death trends, there was no statistical difference. Conclusion: ethnicity/skin color has influenced general incidence curves by COVID-19 in São Paulo. The fact that it was not associated with mortality can be related with the lack of information about ethnicity/color in notification forms, thus affecting the availability of such data in information systems, which reiterates the importance of publicizing quality official epidemiological data.(AU)

Sin embargo, cuando se compararon las tendencias de incidencia por sexo y grupo etario y las tendencias de muerte, no hubo diferencia estadística. Conclusión: la raza/color de piel influyó en las curvas de incidencia general por Covid-19 en el estado de São Paulo, sin embargo, la no-asociación con la mortalidad puede estar relacionada con la falta de información sobre raza/color/etnia en las fichas de notificación, y consecuentemente su disponibilidad en los sistemas de información, reforzando la importancia de la divulgación de datos epidemiológicos oficiales de calidad.(AU)

Association between perceived self-confidence and abilities to distinguish oral mucosal lesions amongst dental students.

INTRODUCTION: Dentists usually refer to difficulties in performing the diagnosis of oral mucosal lesions. This may be attributed to limited access to theoretical lectures and practical training on this subject along the graduation course. The primary aim of this cross-sectional study was to verify if there is an association between the perception of time dedicated to lectures/training and oral diagnosis abilities in oral medicine. The secondary aim was to evaluate the association between self--confidence to perform oral mucosal lesions diagnosis and performance in a diagnostic abilities test. MATERIALS AND METHODS: The sample comprised 36 final-year dental students of a South-Brazilian dental school. The participants answered a questionnaire on their perception of time dedicated to lectures on oral medicine along the course (sufficient or insufficient) and their self-confidence to diagnose oral mucosal lesions or oral cancer (yes or not). The students were also submitted to a diagnostic abilities test based on 30 clinical photos of oral lesions, which should be classified as benign, potentially malignant or malignant. Moreover, the participants had to inform their clinical impression for each case. Finally, the participants informed their decision making for the case (refer the patient to a specialist or not). RESULTS: Students with higher self-confidence showed a higher percentage of correct answers on classification of the nature of lesions (81.1% vs. 68.5%, p = .03, teste t de Student) and on their clinical impression (66.3% vs. 41.7%, p < .01, Student's t-test). The perception of time dedicated to theoretical lectures on oral medicine as sufficient did not influence the students' diagnostic abilities (p > .05, Student's t-test) CONCLUSION: It may be concluded that self-confidence to diagnose oral lesions is associated with dental students' diagnostic abilities.

Primary health care organization in the Covid-19 pandemic: scoping review.

OBJECTIVE: Mapping available scientific evidence on the organization of primary health care services and professionals during the Covid-19 pandemic. METHODS: This is a scoping review that followed the Joanna Briggs Institute method. Articles published in Portuguese, Spanish, and English from January 2020 to January 2021 in the CINAHL, Lilacs, Medline, PubMed, and Web of Science databases were included. RESULTS: We selected 24 articles that presented the reorganization of primary health care services and professionals to care suspected or confirmed Covid-19 cases. Coordination measures to tackle this disease in primary health care help to control its infection, especially by the active search for respiratory symptoms, the detection of new cases, and the monitoring of confirmed cases. CONCLUSION: This study presents an overview of how primary health care services and professionals organized themselves to tackle the Covid-19 pandemic, addressing adjustments in infrastructure and care flows, such as establishing specific Covid-19 care units, separating infected and non-infected patients, using telemedicine as an alternative modality of care, and monitoring cases by applications and phone.

Incorporation of copaiba and oregano essential oils on the shelf life of fresh ground beef patties under display: Evaluation of their impact on quality parameters and sensory attributes.

The preservative effect of the addition of different essential oils (copaiba and oregano) on meat quality parameters and sensorial acceptability was analyzed for fresh ground beef patties over 21 days of display. Five treatments were assessed: control (CON) without antioxidants; addition of the synthetic additive butylated hydroxytoluene (BHT); addition 0.05% of copaiba essential oil (CEO); 0.05% of oregano essential oil (OEO); or blend of 0.025% copaiba and 0.025% oregano essential oils (BEO). The lowest cooking losses and greatest tenderness (P <0.05) were reached with the blend (BEO). The inclusion of oregano essential oil presented a more intense chroma (P <0.05), with the best color retained during display. Oregano essential oil (OEO) and the blend (BEO) showed the highest antioxidant activity, reducing the lipid oxidation of beef patties during display (P < 0.05). Consumers preferred the odor of beef patties with essential oils (OEO and BEO) to the CON; however, the flavor from OEO had the lowest acceptability and the worst scores for overall acceptability (P < 0.05). Patties with the blend addition (BEO) were the best scored on overall acceptability assessments. In conclusion, the oregano and copaiba essential oils blend had a good preservative effect on fresh beef patties during display and increased sensory acceptability of the product, thus being a possible alternative for replacing synthetic compounds in processed foods.

Distance learning course improves primary care dentists' diagnosis and self-efficacy in the management of oral lesions.

Oral cancer represents a public health issue because of its high mortality rate, resulting mainly from diagnostic delays. Insufficient training in oral diagnosis is usually perceived by dentists. Distance learning could be used as an auxiliary tool to bridge that gap. This study evaluated the impact of a distance learning course on oral mucosal lesion diagnosis offered to public healthcare dentists. Participants of an online course answered a pretest/posttest comprising clinical images of 30 clinical cases. Participants were questioned about the diagnosis and informed their decision on the cases (referring the cases to a specialist or managing them themselves), as a parameter of perceived self-efficacy. A total of 442 dentists enrolled in the course. Their pass rate was 97%. Classification of the nature of the lesions, diagnostic hypotheses, sensitivity, and specificity improved by 13.4%, 10.0%, 13.4%, and 6.6%, respectively (p<0.01, Wilcoxon test). Regarding management, there was a 16.6% reduction in the intention to refer cases, while confidence in the diagnosis of benign lesions increased by 40%. A distance learning course may be useful in continuing education actions for primary care dentists, improving their diagnostic abilities and encouraging them in the management of oral lesions. Moreover, this strategy could contribute to disseminating knowledge to remote regions, particularly among primary health care professionals.
