Abstract: Introduction: Stress is a state in which the body homeostasis is threatened, leading to adaptive, physiological and behavioral responses. Anxiety is an unpleasant feeling that occurs whenever a future potential threat is perceived. Whenever these states are prolonged, both lead to metabolic, cardiovascular, neuropsychiatric and immunological consequences. University students are more susceptible to stress and anxiety symptoms than the general population. Mindfulness is a technique that allows its practitioners to become more aware of their emotions, dealing with stress in a more skilled way. Objective: To; evaluate the efficacy of a modified mindfulness program in reducing stress and anxiety symptoms in medicine and dentistry undergraduate students. Methods: This was a single blinded, randomized, clinical trial. Students from the aforementioned courses enrolled in the 1st to the 8th semesters of a higher education institution, answered Lipp’s Inventory of Stress symptoms for Adults (ISSL) (n=418) and the State-Trace Anxiety Inventory (STAI) (n=369). Those who showed a positive score for symptoms of stress and/or anxiety and accepted to take part in the intervention (n=59), were randomized into one of the two groups - mindfulness (a 2-week modified program), or control. After the intervention, the students were asked to answer the STAI and ISSL tools once again. Results: The global prevalence of stress and anxiety symptoms were 67% (n=280) and 76.4% (n=282), respectively. At the end of the second week, symptoms of stress and anxiety decreased 30.8% and 22.2%, respectively. There were no statistically significant differences between the mindfulness and control groups (p>0.05). Conclusion: Symptoms of stress and anxiety are highly prevalent among the studied population. Among medicine and dentistry undergraduate students in this higher education institution, a shortened mindfulness program was unable to reduce symptoms of stress and anxiety in a statistically significant way when compared to a control group.

Resumo: Introdução: O estresse é um estado no qual ocorrem ameaças à homeostase do organismo, com respostas adaptativas fisiológicas e comportamentais. A ansiedade é uma sensação desagradável advinda da percepção de uma ameaça potencial futura. Quando prolongados, ambos levam a repercussões metabólicas, cardiovasculares, imunológicas e neuropsiquiátricas. Os estudantes universitários são mais susceptíveis a sintomas de estresse e ansiedade do que a população em geral. A técnica de mindfulness permite que os seus praticantes se tornem mais conscientes de suas emoções, passando a responder de forma habilidosa ao estresse e à ansiedade Objetivo: Este estudo teve como objetivo avaliar a eficácia de um programa de mindfulness na redução de sintomas de estresse e ansiedade em estudantes de Medicina e Odontologia. Método: Trata-se de um ensaio clínico, randomizado, simples-cego. Acadêmicos regularmente matriculados do primeiro ao oitavo período desses cursos de uma instituição de ensino superior responderam ao Inventário de Sintomas de Stress para Adultos de Lipp (ISSL) (n = 418) e ao Inventário de Ansiedade Traço-Estado (IDATE) (n = 369). Os participantes que apresentaram sintomas de estresse e/ou ansiedade e aceitaram participar da intervenção (n = 59) foram randomizados em grupos mindfulness (programa modificado de duas semanas) e de controle. Ao final da intervenção, o ISSL e o IDATE foram reaplicados. Resultado: As prevalências globais de estresse e ansiedade foram de 67% (n = 280) e 76,4% (n = 282), respectivamente. Ao final da segunda semana, a redução dos sintomas de estresse e ansiedade foi de 30,8% e 22,2%, respectivamente. Não houve diferença estatisticamente significativa entre os grupos mindfulness e de controle (p > 0,05). Conclusão: Percebe-se uma alta prevalência de sintomas de estresse e ansiedade na população estudada. Um programa de mindfulness em formato reduzido não foi capaz de diminuir significativamente os sintomas de estresse e ansiedade em comparação ao grupo de controle, em acadêmicos de Medicina e Odontologia dessa instituição.

Abstract: Background: Exposure to UVR provides benefits related to vitamin D synthesis, but also causes harms, since UVB is considered a complete carcinogen. There is no definition of the level of sun exposure and the proportion of exposed body required for proper synthesis of vitamin D in the skin without causing it damage. Objectives: This study aims to analyze the sun exposure index, vitamin D levels and clinical changes in the skin caused by constant sun exposure in the fishermen population. Methods: It is a cross-sectional, observational and analytical study. The sample consisted of fishermen and was calculated in 174 individuals. The questionnaire was applied, the dermatological examination was carried out and the examinations of calcidiol, parathyroid hormone, calcium and phosphorus were requested. Data were expressed as percentages. The comparative analysis was done through the Chi-square test, and the correlations were established through the Pearson's linear coefficient. Results: We observed that there was vitamin D deficiency in a small part of the cases (11.46%), and the frequency of diagnosis of skin cancer was 2.7% of the cases surveyed. Study Limitations: The difficulty in categorizing the sun exposure index. Conclusion: The fact that fishermen expose themselves to the sun chronically and have been exposed to the sun for more than 15 years, between 21 and 28 hours a week, and without photoprotection, were indicative factors for protection against vitamin D deficiency. Chronic exposure to sun and high vitamin levels D may be indicative of protection of this population against skin cancer.

Abstract Objective: To evaluate the influence of gustatory stimuli on the buffering capacity of saliva. Material and Methods: The buccal ph of 18 male volunteers aged 18-35 years was measured after a mouthwash with 20 ml of water as a control, and in individual disposable cups they collected the saliva for two minutes. Then, each of chewed bubble gum with sugar for two minutes, discarding the gum and made new collection of saliva, for two minutes in other disposable cups individualized. After collection, each volunteer was again subject to regular brushing with toothpaste and waited another ten minutes. The same procedure was repeated with all other substances. Salivary buffer capacity was determined by Ericsson technique. Data were submitted to analysis of variance and the means were compared by the Scott-Knott grouping test and Mann-Whitney test at 5% probability. Estimates of Pearson correlations were calculated in order to determine possible associations between the variables. Results: It was not found statistically significant differences between the initial pH variation and after eating food (p>0.05), or between gustatory stimulation and variation of salivary buffer capacity (p>0.05). Conclusion: There is no influence of gustatory stimulus aroma and flavor on the variation of salivary buffer capacity.

RESUMO Objetivo: analisar a associação de sintomas vocais autorreferidos com aspectos pessoais, ocupacionais, clínicos e relacionar com a qualidade de vida de professores da rede federal de ensino profissional e tecnológico. Métodos: estudo com 157 docentes de uma instituição pública federal de educação profissional e tecnológica, que responderam aos questionários World Health Organization Quality Of Life/bref (WHOQOL-bref), Qualidade de Vida em Voz (QVV) e o formulário de dados (sociais, condições de saúde, sintomas vocais, hábitos, organização e ambiente de trabalho). A análise estatística foi realizada por meio do teste Qui-quadrado. Resultados: 29% dos professores apresentaram sintomas vocais. As queixas prevalentes foram garganta seca (38,2%), tosse (37,6%) e rouquidão (30,6%). Houve maior prevalência dos sintomas no sexo feminino. Para o WHOQOL-bref, a média foi 71,3 pontos, considerada regular. O domínio com maior pontuação foi o psicológico com 75,3. Quanto ao QVV, o escore médio no domínio global foi de 92,5 pontos, sendo o físico o mais comprometido. 90,5% dos docentes apresentaram baixo impacto da voz na qualidade de vida. Conclusão: embora os docentes apresentem queixas vocais, elas não se refletem na limitação da qualidade de vida.

ABSTRACT Purpose: to analyze the association of self-reported vocal symptoms with personal, occupational and clinical aspects and relate them to the quality of life of teachers/professors of the federal network of vocational and technological education. Methods: study carried out with 157 teachers from a federal public institution of vocational and technological education, who answered the World Health Organization Quality of Life questionnaire (WHOQOL-bref), Quality of Life in the Voice (V-RQOL) questionnaire and a data form (on social information, health conditions, vocal symptoms, habits, organization and working environment). Statistical analysis was performed using the Chi-square test. Results: 29% of the teachers presented vocal symptoms. The prevalent complaints were dry throat (38.2%), cough (37.6%) and hoarseness (30.6%). There was a higher prevalence of symptoms in females. For the WHOQOL-bref, the average was 71.3 points, which is considered regular. The domain with the highest score was the psychological one with 75.3. Regarding V-RQOL, the average score in the global domain was 92.5 points, and the physical score was the most compromised one. 90.5% of teachers showed low voice impact on quality of life. Conclusion: although these teachers present vocal complaints, they do not reflect in the limitation of the quality of life.
