OBJECTIVE: In 2020, the COVID-19 pandemic brought a work and stress overload to healthcare workers, increasing their vulnerability to mental health impairments. In response, the authors created the COMVC-19 program. The program offered preventive actions and mental health treatment for the 22,000 workers of The Hospital das Clinicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP). This paper aims to describe its implementation and share what we have learned from this experience. METHODS: Workers were able to easily access the program through a 24/7 hotline. Additionally, a mobile phone app that screened for signs and symptoms of emotional distress and offered psychoeducation and/or referral to treatment was made available. Data from both these sources as well as any subsequent psychiatric evaluations were collected. RESULTS: The first 20 weeks of our project revealed that most participants were female, and part of the nursing staff working directly with COVID-19 patients. The most frequently reported symptoms were: anxiety, depression and sleep disturbances. The most common diagnoses were Adjustment, Anxiety, and Mood disorders. CONCLUSIONS: Implementing a mental health program in a multimodal intervention was feasible in a major quaternary public hospital. Our data also suggests that preventive actions should primarily be aimed at anxiety and depression symptoms, with a particular focus on the nursing staff.

RESUMO Objetivo Evidenciar os fatores predisponentes relativos à ansiedade em minorias sexuais e de gênero na literatura. Métodos Trata-se de uma revisão integrativa. A busca dos artigos foi realizada em três bases de dados eletrônicas: PubMed/Medline, Scopus e ISI Web of Knowledge . Foram utilizados os descritores “ anxiety ”, “ LGBT people ”, “ gay ”, “ bisexual ”, “ lesbian ” e “ transgender ”, com textos completos, publicados no período de 2013 a 2018, no idioma inglês, e foi usado o operador boleano AND . Resultados Foram encontrados 712 artigos. Cinquenta e oito (58) artigos foram selecionados para serem lidos na íntegra e 13 atenderam aos critérios de inclusão desta revisão. As evidências mostram que a população LGBT apresenta maior risco para transtornos mentais, entre eles a ansiedade, quando comparada aos heterossexuais. O aparecimento dos sinais e sintomas de ansiedade estão relacionados com a vergonha e o comportamento evitativo dessa população devido à forte discriminação e à ausência de apoio social e familiar, o que ocasiona altos níveis de angústia. Apenas dois artigos estudaram menores de 18 anos. Conclusões Os profissionais da saúde devem estar abertos, acolhedores e atentos à saúde mental desse público, visando contribuir com a promoção da saúde, apoio social, familiar e a redução da discriminação.

ABSTRACT Objective To evidence the predisposing factors related to anxiety in sexual and gender minorities in the literature. Methods This is an integrative review. The search of the articles was conducted in three databases: PubMed/Medline, Scopus and ISI Web of Knowledge. The descriptors "anxiety", "LGBT people", "gay", "bisexual", "lesbian" and "transgender" were used, with complete texts, published between 2013 and 2018, in the English language, boolean operator AND was used. Results A total of 712 articles were found. Fifty-eight (58) articles were selected to be read in their entirety and 13 met the inclusion criteria of this review. Evidence shows that LGBT people is at higher risk for mental disorders, including anxiety, when compared to heterosexual. The appearance of signs and symptoms of anxiety are related to shame and the avoidant behavior of this population due to the strong discrimination and lack of social and family life, which causes high levels of distress. Only two articles studied minors 18 years old. Conclusions Health professionals should be welcoming and attentive to health mental health of this public, with a view to contributing to health promotion, social and family support and reduction of discrimination.

ABSTRACT. The objective of this study was to evaluate the inclusion of protease and sugarcane yeast in poultry diets on performance, organ weight, intestinal biometry, chemical composition and deposition of body nutrients in the 1 to 7-day old phase. The experimental design consisted of a randomized complete block design, in a factorial arrangement of 2 (without and with the enzyme protease) x3 (yeast levels: 0, 6 and 12%) +1 (positive control diet), totaling seven treatments with five replicates, birds per experimental unit. The treatments used consisted of a positive control diet and the others were the negative control, with reductions in nutritional levels of protein and amino acids by 4% requirement. In the negative control diets, protease enzyme was included in three levels of sugarcane yeast. In isolation, treatments with or without inclusion of protease influenced the chemical composition of the birds. The levels of yeast from sugarcane yeast presented effects for weight gain, feed conversion, moisture and crude protein in the nutrient deposition. The inclusion of protease in diets for broiler chicks cannot remedy the poor performance provided by the use of sugarcane yeast, in addition to presenting lower levels of deposition of body nutrients.

ABSTRACT The objective of this study was to evaluate the effect of three levels of crude cottonseed oil on performance, organ weights, and blood parameters of growing broilers. Carcass and cut yields after 33 and 42 days of age and the economic viability of the diets were also evaluated. Male broilers of the Ross line were distributed in a completely randomized design, in a 4 × 2 factorial arrangement (0, 2, 4, and 6% inclusion of cottonseed oil, with and without ferrous sulfate) with five replicates. In the period from 22 to 33 days, quadratic and increasing linear effects were observed on feed intake and weight gain, respectively. Feed conversion during the same period was better with the addition of ferrous sulfate. The addition of ferrous sulfate caused a reduction in heart weight. From 22 to 42 days, carcass and cuts yield, organ weight, and intestine length were not influenced by the levels of oil or by the addition of ferrous sulfate. Supplementation with iron salts provided a lower red blood cell count and increased mean cell volume. Balanced diets formulated with up to 6% of crude cottonseed oil for broilers from 22-33 and 22-42 days of age do not affect their performance or the weight of their organs. Supplementation with ferrous sulfate improved feed conversion up to 33 days. Diets formulated with 4% cottonseed oil supplemented with ferrous sulfate are economically viable in the period from 22 to 42 days.

RESUMO O Programa Segundo Tempo (PST) é o mais amplo programa social orientado para a participação de crianças, adolescentes e jovens no esporte atualmente no Brasil. No entanto, ainda sabemos pouco sobre o alcance dos seus objetivos, especialmente em relação ao macrossistema. Objetivo desse estudo é analisar o alcance do PST em relação à democratização do acesso à prática e à cultura de esporte. Trata-se de um estudo exploratório realizado no contexto do PST. Foram utilizados dados secundários, de acesso público e administrado por órgãos oficiais. Foi tomado como indicador do macrossistema o Índice de Desenvolvimento Humano dos Municípios (IDHM), número de convênios e a população estimada de municípios que mantiveram convênios com o Ministério do Esporte para o PST entre 2003-2013. Concluímos que os municípios com os melhores indicadores sociais e estrutura para o esporte conseguiram ter mais acesso ao PST, além de conseguir manter por mais tempo.

ABSTRACT The “Segundo Tempo” Program (PST) is the largest social program aimed at the youth participation in sport currently in Brazil. However, we still know little about the scope of its objectives, particularly in relation to the macro-system. The aim of this study is to analyze the scope of the PST in relation to the democratization of access to sport practice and culture. This is an exploratory study in PST context. Secondary data from public access and official agencies managed was used. It was taken as macro-indicator the Human Development Index of Municipalities (HDIM), number of agreements and the estimated population of municipalities that have maintained agreements with the Ministry of Sports for the PST from 2003 to 2013. We conclude that the municipalities with the best social indicators and structure for sport practice have more access to the PST, and can keep it longer.

A fitoextração de metais pesados usando agentes quelantes tem sido amplamente estudado para a remediação de solos contaminados. Para avaliar a eficiência do EDTA na fitoextração induzida de Ba e Pb, usando Brachiaria decumbens para a remediação de solos contaminados por perfuração poço de petróleo e resíduos de exploração, foi conduzido um experimento, aplicando uma dose única (6 mmol EDTA kg-1 solo) e divisão de doses de EDTA (três aplicações de 2 mmol EDTA kg-1 solo). As amostras foram submetidas a extrações sequenciais com o método proposto por Ure et al. (1993), conforme modificado por Rauret et al. (1999). A aplicação de EDTA não influenciou a distribuição do Ba nas diferentes frações geoquímicas. A produção de matéria seca não diferiu significativamente entre os tratamentos e o controle, demonstrando assim a tolerância das plantas com as condições experimentais. Houve maior absorção de Pb pelas plantas com a aplicação de EDTA. A aplicação de uma dose única de EDTA influenciou a absorção de Pb e sua translocação para a parte aérea das plantas. A aplicação dividida das doses favoreceu maior acúmulo de Pb nas raízes. Devido à sua tolerância para os metais pesados EDTA, B. decumbens tem o potencial para ser utilizado em fitoestabilização.

The phytoextraction of heavy metals using chelating agents has been widely studied for the remediation of contaminated soils. To evaluate the efficiency of EDTA-induced phytoextraction of Ba and Pb using Brachiaria decumbens for the remediation of soil contaminated by oil well drilling and exploration waste, an experiment was conducted by applying a single dose (6 mmol EDTA kg-1 soil) and split doses of EDTA (three applications of 2 mmol EDTA kg-1 soil). The samples were subjected to sequential extractions using the method proposed by Ure et al. (1993) as modified by Rauret et al. (1999).The application of EDTA did not influence the distribution of Ba in various chemical fractions of the soil. The dry matter production did not differ significantly between the treatments and the control, thereby demonstrating the tolerance of plants to the experimental conditions. The absorption of Pb by plants was influenced by the application of EDTA. The application of a single dose of EDTA influenced the absorption of Pb and its translocation to the aerial plant parts. The application of split doses favoured higher accumulation of Pb in roots. Because of its tolerance to heavy metals and EDTA, B. decumbens has the potential to be used in phytostabilisation.

Abstract: En | Text: En | PDF: En

PURPOSE: To investigate the effects of occupational exposure to waste anesthetic gases on genetic material and antioxidant status in professionals during their medical residency.METHODS: The study group consisted of 15 medical residents from Anesthesiology and Surgery areas, of both genders, mainly exposed to isoflurane and to a lesser degree to sevoflurane and nitrous oxide; the control group consisted of 15 young adults not exposed to anesthetics. Blood samples were drawn from professionals during medical residency (eight, 16 and 22 months of exposure to waste anesthetic gases). DNA damage was evaluated by comet assay, and antioxidant defense was assessed by total thiols and the enzymes glutathione peroxidase (GPX), superoxide dismutase (SOD) and catalase (CAT).RESULTS: When comparing the two groups, DNA damage was significantly increased at all time points evaluated in the exposed group; plasma thiols increased at 22 months of exposure and GPX was higher at 16 and 22 months of exposure.CONCLUSION: Young professionals exposed to waste anesthetic gases in operating rooms without adequate scavenging system have increased DNA damage and changes in redox status during medical residency. There is a need to minimize exposure to inhalation anesthetics and to provide better work conditions.

INTRODUÇÃO: O comprometimento da qualidade de vida das pessoas acometidas pelo câncer pode causar danos devastadores. A auto-imagem dos pacientes pós-laringectomizados poderá encontrar-se comprometida, interferindo na qualidade de vida desta população. OBJETIVO: Caracterizar qualidade de vida em comunicação em pessoas que foram submetidas à laringectomia total. MÉTODO: Trata-se de um estudo do tipo observacional, transversal, descritivo. Desenho do tipo estudos de séries. Participaram do estudo 15 pacientes, no período de janeiro a fevereiro de 2011. Utilizou-se o Protocolo de Qualidade de Vida em Comunicação em Pós-laringectomizados adaptado de Bertocello (2004), que contém 55 questões. O protocolo foi organizado a partir da natureza das respostas classificadas em aspecto positivo e negativo, propostas em cinco domínios de comunicação: relação familiar; relação social; análise pessoal; aspecto morfofuncional; uso da escrita. Para promoção e garantia da autonomia dos respondentes, fez-se uso de tecnologia assistiva com a Escala de Resposta Visual. RESULTADOS: As respostas que comprometem a qualidade de vida em comunicação somaram 463 ocorrências (65,7%), e as que sugerem boa qualidade de vida foram representadas com 242 ocorrências (34,3%), de um total de 705 ocorrências. Dos cinco domínios da comunicação, quatro obtiveram percentuais acima de 63% ocorrências de teor negativo para a comunicação. Em aspecto morfofuncional, obteve-se o maior percentual de teor negativo, 77,3% das ocorrências. CONCLUSÕES: Os resultados apontaram limitações importantes de natureza pessoal e social decorrentes de uma comunicação precária com seus pares. Assim, há necessidade de intervenções multidisciplinares que visem minimizar o enclausuramento comunicacional dessas pessoas.

INTRODUCTION: Among people affected by cancer, the impairment of quality of life of people affected by cancer can cause have devastating effects. The self-image of patients after post-laryngectomyzed patients may be find themselves compromised, affecting the quality of life in this population. OBJECTIVE: To characterize quality of life in related to communication in people who have undergone went total laryngectomy surgery. METHODS: This is an observational study, with a cross-sectional and descriptive series. DESIGN OF SERIES STUDY. The sample were comprised 15 patients interviewed the period from January to February of 2011. We used the Quality Protocol for Life Communication in Post-laryngectomy adapted from Bertocello (2004); which this questionnaire contains 55 questions. The protocol was organized from the nature of using responses classified as positive and negative aspects, proposals in with respect to five 5 communication domains: family relationships, social relationships, personal analysis; morphofunctional aspect, and use of writing. To promote and guarantee the autonomy of the respondents, was examiners made use of used assistive technology with the Visual Response Scale.

OBJETIVO: Caracterizar a atividade elétrica muscular do masseter durante a deglutição de líquido em indivíduos adultos jovens saudáveis. MÉTODOS: A população constou de 14 voluntários considerados saudáveis seguindo os critérios de inclusão e exclusão estabelecidos para esta pesquisa. Foi realizada avaliação eletromiográfica do músculo masseter bilateralmente, durante o repouso e nas tarefas de deglutição de 14,5 ml, 20 ml e 100 ml de líquido. O sinal eletromiográfico foi normalizado pela máxima atividade voluntária resistida (MAVR), considerada como 100% de atividade elétrica muscular. RESULTADOS: No masseter direito, a maior média percentual foi encontrada na tarefa de deglutição de 20 ml e no masseter esquerdo na tarefa de 14,5 ml. No masseter direito ocorreu diferença entre as deglutições de 14,5 ml e 20 ml. No masseter esquerdo não houve diferença entre as tarefas de deglutição. CONCLUSÃO: A atividade elétrica muscular do masseter em adultos jovens saudáveis durante a deglutição de líquido pode ser influenciada pelo volume deglutido e apresenta diferentes respostas bilateralmente.

PURPOSE: To characterize the electrical activity of the masseter muscle during swallowing of liquids in healthy young adults. METHODS: Participants were 14 volunteers considered healthy according to the inclusion and exclusion criteria established for this study. The bilateral electromyographic evaluation of the masseter muscle was conducted at rest and in swallowing tasks of 14.5 ml, 20 ml and 100 ml of liquid. The electromyographic signal was normalized by the maximum voluntary activity resisted (MVAR), considered as 100% of the muscle's electrical activity. RESULTS: In the right masseter, the highest average percentage was found in the 20 ml task, and in the left masseter, in the 14.5 ml task. In the right masseter there was difference between the 14.5 ml and the 20 ml swallowing tasks. In the left masseter, no differences were found between the swallowing tasks. CONCLUSION: The electrical activity of the masseter muscle in healthy young adults during deglutition of liquids can be influenced by volume swallowed, and present different responses bilaterally.

In order to evaluate possible solubility of BaSO4 in soils under reducing conditions, column leaching assay was settled down, where the soil received three doses of BaSO4 (100, 300 and 3000 mg kg-1) at two humidities. After reaching an Eh of -200 mV rainfall of 200 mm per day-1 was simulated. The condition of reduction led to the increased levels of barium in the fractions of higher lability and the highest levels of barium in the leachate extract, which were above the potability standards. Only 0.05% of barium in the column that received the highest dose was removed by leaching.

Um experimento foi conduzido com o objetivo de estudar os efeitos dos níveis de cálcio nas rações sobre o desempenho e a qualidade de ovos de poedeiras comerciais. Foram utilizadas 216 poedeiras da linhagem Lohmann Brown no período de 39 a 55 semanas de idade. O delineamento utilizado foi inteiramente casualizado, composto de seis níveis de cálcio (3,0; 3,4; 3,8; 4,2; 4,6; 5,0%) e seis repetições de seis aves por parcela. Os níveis de cálcio avaliados não influenciaram os parâmetros produtivos, mas afetaram significativamente as porcentagens de albúmen e casca do ovo. O aumento do cálcio na dieta promove incremento na qualidade da casca do ovo em relação aos demais componentes do ovo. Recomenda-se nível de 4,3% de cálcio em dietas para poedeiras semipesadas após o pico de postura.

Two hundred and sixteen layers were raised from 39 to 55 weeks of age to study the effects of levels of calcium in the rations on performance and eggs quality of brown commercial layers. A completely randomized experimental design were used with six levels of calcium (3.0; 3.4; 3.8; 4.2; 4.6 and 5.0%) and six replicates of six layers hens. There was no effect of calcium levels on hen performance, however significantly affected the percentage of albumen and egg shell. The increase of calcium in the diet promoted increment in egg shell quality in relationship to other eggs components. The calcium level of 4.3% is recommended for brown layer hens after production peak.

O experimento foi desenvolvido no aviário de Departamento de Zootecnia do Centro de Ciências Agrárias da UFPB, em Areia-PB. Foram utilizadas 432 pintainhas Lohmann Brown de três dias de idade, distribuídas em um delineamento inteiramente casualizado, em esquema Fatorial 3x3, com três níveis de PB e três níveis de EM. Na primeira fase, de 1 a 6 semanas de idade, as aves foram alimentadas com rações contendo três níveis de PB (21, 22 e 23%) e três de EM (2900, 3000 e 3100kcal/kg de ração). Na segunda e terceira fases, as aves com idades de 7 a 12 e de 13 a 18 semanas, respectivamente, foram alimentadas com três níveis de PB sendo 18, 19 e 20% de sete a doze semanas e 16, 17 e 18% de treze a dezoito semanas e três níveis de EM sendo 2700, 2800 e 2900kcal/kg de ração nessas duas fases. Não foi encontrada interação entre os níveis de PB e de EM. Com base nos resultados obtidos, recomenda-se, respectivamente, para as fases de 1 a 6, de 7 a 12 e de 13 a 18 semanas de idade, os níveis de 21% de PB e 2900 kcal de EM/kg de ração, 20% de PB e 2700 kcal de EM/kg de ração e 16% de PB e 2700 kcal de EM/kg de ração.

The aim of this experiment was to evaluate the performance of commercial layers between 1 and 18 weeks of age submitted to different crude protein (CP) and metabolizable energy (ME) levels. The trial was carried out at the poultry sector of the Department of Animal Science, of the Centro de Ciências Agrárias, Universidade Federal of Paraiba, Areia-PB, Brazil. Four hundred and thirty-two Lohmann Brown chicks were used at 3 days of age according to a completely randomized design in a 3 x 3 factorial scheme, with three CP levels and three ME levels. In the first phase (1-6 wk), the birds were fed with diets containing three levels of CP: 21, 22 or 23% CP and three levels of ME: 2,900, 3,000 and 3,100 kcal/kg diet. In the second phase (7-12 wk) and in the third phases (13-18 wk), CP levels of feeding were 18, 19 or 20%, and 16, 17 or 18%, respectively, and three ME levels being 2,700, 2,800 or 2,900 kcal ME/kg diet in these two phases. It was not found interaction between CP and ME levels. Based on the results obtained one recommends for the phases from 1 to 6, 7 to 12 and 13 to 18 weeks of age the levels of 21 % of CP and 2900 kcal of ME /kg diets, 20% of CP and 2700 kcal of ME/kg diets and 16% of CP and 2700 kcal of ME/kg diets respectively.
