ABSTRACT

ABSTRACT Objective: Obesity is an important factor for cardiovascular and metabolic events. Thus, this study aimed to assess the prevalence of overweight/obesity and the associated factors among healthcare university students. Materials and methods: A cross-sectional university-based study of 2,245 healthcare university students in the Midwest region of Brazil was conducted in 2018. Overweight and obesity were defined as body mass index (BMI) ≥ 25 kg/m2 and BMI ≥ 30 kg/m2, respectively. Demographic, socioeconomic, behavioral, family and comorbidities characteristics were investigated. Poisson regression was used for the multivariable analysis. All analysis was stratified by sex. Results: The mean age of the sample was 22.7 years (standard deviation = 4.1) and 69.5% of the students was female. The prevalence of overweight and obesity were 13.9% (95% confidence interval [CI]: 12.2-15.6) and 4% (95% CI: 3.0-4.9) for women and 34.5% (95% CI: 30.9-38.1) and 11.3% (95% CI: 8.9-13.6) for men, respectively. After multivariate adjustment, the prevalence of overweight/obesity was at least 70% higher in female students aged 24 years or older (prevalence ratio [PR] = 1.73; 95% CI: 1.24-2.41) and those who smoke (PR = 1.95; 95% CI: 1.66-3.02). Additionally, female students with a family history of obesity (PR = 2.01; 95% CI: 1.46-2.77) or with two or three comorbidities (PR = 2.09; 95% CI: 1.43-3.04) exhibited a significantly higher probability for overweight/obesity. Similar findings were observed in male students, but with smaller effect sizes. Conclusion: This study revealed a high prevalence of overweight/obesity among healthcare university students, especially in men. It was related to the socio-demographic and family characteristics rather than behavioral factors.

ABSTRACT

Resumo: A translação do conhecimento (TC) tem como propósito a utilização prática dos resultados de pesquisas científicas e o monitoramento dos benefícios causados à saúde da população. Na área de saúde, o governo e, principalmente, a sociedade esperam que os investimentos em pesquisas obtenham resultados que vão além da produção e da publicação do conhecimento, e provoquem soluções como políticas públicas, sistemas, produtos e tecnologias para beneficiar a saúde da população. Contudo, verifica-se ainda a necessidade de superar diversos desafios para eliminar as lacunas existentes entre a investigação e a aplicação. O objetivo deste estudo é propor estratégias, com base na identificação de barreiras e fatores facilitadores de um instituto de ciência e tecnologia (ICT) em saúde, para fomentar o processo de transformação do conhecimento científico, gerado nas pesquisas, em ações e produtos que contribuam para a melhoria da saúde da população. Os relatos das entrevistas, realizadas com 16 pesquisadores, permitiram a identificação de 10 categorias de barreiras, tendo destaque: "financiamento em ciência, tecnologia e informação (CT&I) limitado" e "apoio técnico insuficiente para a translação do conhecimento". "Infraestrutura e apoio institucional" foi a categoria de fatores facilitadores mais citada pelos participantes. Por fim, foi desenvolvido o artefato "estratégias e abordagens para superação de barreiras à implementação de resultados de pesquisa". Entre as estratégias, sugere-se a inclusão de uma disciplina de TC nos programas de pós-graduação stricto sensu e a criação de uma instância na estrutura organizacional do ICT voltada à prestação de suporte técnico e gerencial à aplicação de resultados de pesquisa.


Abstract: Knowledge translation (KT) aims at the practical use of scientific research results and at the monitoring of the benefits caused to the population's health. In health, the government and especially society expect that investments in research will produce results that go beyond the production and publication of knowledge, provoking outcomes such as public policies, systems, products, and technologies to benefit the health of the population. However, closing the gaps between research and application requires overcoming a number of challenges. This study aimed to propose strategies to foster the process of transforming the scientific knowledge generated in research into actions and products that contribute to improving the population's health based on the identification of barriers and facilitating factors of a health science and technology institute. The reports of interviews conducted with 16 researchers showed 10 categories of barriers, especially: "limited funding to the science and technology institute" and "insufficient technical support for knowledge translation". "Infrastructure and institutional support" was the facilitating factor category participants mentioned the most. Finally, we developed the artifact "strategies and approaches for overcoming barriers to implement research results". Among the strategies, we suggest the inclusion of a knowledge translation discipline in stricto sensu graduate programs and the creation of an instance in the organizational structure of the science and technology institute to technically and managerially support the application of research results.

ABSTRACT

ABSTRACT The objective of this study was to report a clinical case of facial rehabilitation with an acrylic implant-retained nasal prosthesis after partial rhinectomy resulting from the resection of a basal cell carcinoma in the patient, a 53-year-old Caucasian, normosystemic, professional cowboy. After clinical examination and in possession of computed tomography images, surgery was performed for the placement of conventional dental implants in the premaxillary region (left side). After the surgery, a three-month period of waiting was observed to allow osseointegration of the implants. Later, the nasal prosthesis was prepared, and at the end of treatment, this presented satisfactory peripheral adaptation, retention and esthetics. The patient has returned for follow-up every 6 months, regarding analysis of the prosthesis color, peri-implant health, hygiene, and exchange of the magnets and relays when necessary. The authors concluded that this therapy may be well indicated in patients with partial and total nasal defects, provided that there is correct planning and execution of the surgical, clinical and laboratory phases.


RESUMO O objetivo deste trabalho é relatar um caso clínico de reabilitação facial com prótese nasal acrílica implanto-retida pós-rinectomia parcial decorrente da ressecção de um carcinoma basocelular em um paciente do sexo masculino, vaqueiro, 53 anos de idade, caucasiano e normossistêmico. Após exame clínico e de posse da tomografia computadorizada, foi realizada a cirurgia de instalação dos implantes dentários convencionais na região da pré-maxila (lado esquerdo). Depois de realizada a cirurgia, esperou-se a osseointegração dos implantes por três meses e, posteriormente, foi realizada a confecção da prótese nasal que, ao final do tratamento, apresentou adaptação periférica, retenção e estética satisfatórias. O paciente tem retornado a cada 6 meses para proservação quanto à análise da cor da prótese, saúde periimplantar, higienização, troca dos magnetos e reembasamentos quando necessários. Os autores concluem que essa terapia pode ser bem indicada em defeitos nasais parciais e totais, desde que haja correto planejamento e execução das fases cirúrgica, clínica e laboratorial.

ABSTRACT

ABSTRACT OBJECTIVE: To analyze the cost effectiveness of the diagnostic program for the germline mutation in BRCA1/2 genes and of preventative strategies for the relatives of patients diagnosed with ovarian cancer associated with this mutation. METHODS: The study analyzed the cost effectiveness by developing an analysis of the Markov decision process from the perspective of the National Health System. The strategies compared reflect upon the adoption of genetic testing and preventative strategies for relatives or the usual care currently proposed. The incremental cost-effectiveness ratio was expressed in terms of cost per case avoided. The sensitivity analysis was performed in a univariate and deterministic manner. RESULTS: The study showed increments for effectiveness and for costs when performing genetic testing and adopting prophylactic measures for family members. The incremental cost-effectiveness ratio was estimated at R$908.58 per case of cancer avoided, a figure considered lower than the study's cost-effectiveness threshold (R$7,543.50). CONCLUSIONS: The program analyzed should be considered a cost-effective strategy for the national situation. Studies in various other countries have reached similar conclusions. One possible ramification of this research might the need to perform a budgetary-impact analysis of making the program one of the country's health policies.

ABSTRACT

ABSTRACT Introduction: The etiology of pulmonary infections in HIV patients is determined by several variables including geographic region and availability of antiretroviral therapy. Materials and methods: A cross-sectional prospective study was conducted from 2012 to 2016 to evaluate the occurrence of pulmonary fungal infection in HIV-patients hospitalized due to pulmonary infections. Patients' serums were tested for (1-3)-β-D-Glugan, galactomannan, and lactate dehydrogenase. The association among the variables was analyzed by univariate and multivariate regression analysis. Results: 60 patients were included in the study. The patients were classified in three groups: Pneumocystis jirovecii pneumonia (19 patients), community-acquired pneumonia (18 patients), and other infections (23 patients). The overall mortality was 13.3%. The time since diagnosis of HIV infection was shorter in the pneumocystosis group (4.94 years; p = 0.001) than for the other two groups of patients. The multivariate analysis showed that higher (1-3)-β-D-Glucan level (mean: 241 pg/mL) and lactate dehydrogenase (mean: 762 U/L) were associated with the diagnosis of pneumocystosis. Pneumocystosis was the aids-defining illness in 11 out of 16 newly diagnosed HIV-infected patients. Conclusion: In the era of antiretroviral therapy, PJP was still the most prevalent pulmonary infection and (1-3)-β-D-Glucan and lactate dehydrogenase may be suitable markers to help diagnosing pneumocystosis in our HIV population.

ABSTRACT

ABSTRACT The increasing loss of local ecological knowledge may have negative impacts on the resilience of socio-ecological systems and may also negatively impact bioprospecting efforts, since local ecological knowledge is an important source of information for searching new drugs. Recent studies try to evaluate whether communities are experiencing loss of local ecological knowledge. However, some of them make conclusions which are erroneously based on specific analyses of a single indicator. We propose an integrative analysis of three indicators, namely: number of plants cited by young people and elders, therapeutic choices and people's connectance in terms of medicinal plant learning. The study was carried out in the community of Sucruiuzinho (Bahia, Brazil). We conducted semistructured interviews and a therapeutic recall with 24 local dwellers. We did not find evidence of local ecological knowledge loss in the studied community. Although younger people know fewer plants, they are well connected in terms of knowledge transmission. Moreover, in illness events, young people and adults have similar proportions of choice for plants when compared to allopathy. Concomitant use of the three indicators leads to a more realistic scenario of local ecological knowledge loss than the use of only one of them.

ABSTRACT

OBJECTIVE To analyze if size, administrative level, legal status, type of unit and educational activity influence the hospital network performance in providing services to the Brazilian Unified Health System.METHODS This cross-sectional study evaluated data from the Hospital Information System and the Cadastro Nacional de Estabelecimentos de Saúde (National Registry of Health Facilities), 2012, in Sao Paulo, Southeastern Brazil. We calculated performance indicators, such as: the ratio of hospital employees per bed; mean amount paid for admission; bed occupancy rate; average length of stay; bed turnover index and hospital mortality rate. Data were expressed as mean and standard deviation. The groups were compared using analysis of variance (ANOVA) and Bonferroni correction.RESULTS The hospital occupancy rate in small hospitals was lower than in medium, big and special-sized hospitals. Higher hospital occupancy rate and bed turnover index were observed in hospitals that include education in their activities. The hospital mortality rate was lower in specialized hospitals compared to general ones, despite their higher proportion of highly complex admissions. We found no differences between hospitals in the direct and indirect administration for most of the indicators analyzed.CONCLUSIONS The study indicated the importance of the scale effect on efficiency, and larger hospitals had a higher performance. Hospitals that include education in their activities had a higher operating performance, albeit with associated importance of using human resources and highly complex structures. Specialized hospitals had a significantly lower rate of mortality than general hospitals, indicating the positive effect of the volume of procedures and technology used on clinical outcomes. The analysis related to the administrative level and legal status did not show any significant performance differences between the categories of public hospitals.


OBJETIVO Analisar se porte, esfera administrativa, natureza jurídica, tipo de unidade e atividade de ensino influenciam o desempenho de rede hospitalar prestadora de serviços ao Sistema Único de Saúde.MÉTODOS Neste estudo transversal foram avaliados dados disponíveis no Sistema de Informações Hospitalares e no Cadastro Nacional de Estabelecimentos de Saúde de 2012, no estado de São Paulo, Brasil. Foram calculados indicadores de desempenho como: relação de pessoas por leito; valor médio da autorização de internação hospitalar paga; taxa de ocupação hospitalar; tempo médio de permanência; índice de rotatividade; e taxa de mortalidade hospitalar. Dados foram expressos em média e desvio-padrão. Os grupos foram comparados utilizando-se análise de variância (ANOVA) e correção de Bonferroni.RESULTADOS A taxa de ocupação hospitalar em hospitais de pequeno porte mostrou-se inferior a de hospitais de porte médio, grande e especial. Observaram-se maiores taxas de ocupação hospitalar e índice de rotatividade nos hospitais com atividade de ensino. A taxa de mortalidade hospitalar apresentou-se inferior nos hospitais especializados, em comparação com hospitais gerais, apesar da maior proporção de internações de alta complexidade. Não foram observadas diferenças entre hospitais da administração direta e indireta para a maioria dos indicadores analisados.CONCLUSÕES O estudo indicou a importância do efeito escala para a eficiência, de modo que hospitais de maior porte apresentaram desempenho superior. A presença de atividades de ensino determinou maior desempenho operacional, ainda que tenha se associado à importante utilização de recursos humanos e de estrutura de alta complexidade. Os hospitais especializados apresentaram taxa de mortalidade hospitalar sensivelmente inferior a de hospitais gerais, indicando o efeito positivo do volume de procedimentos e da tecnologia empregada sobre o desfecho clínico. As análises relativas à esfera administrativa e à natureza jurídica não mostraram diferenças significativas de desempenho entre as categorias de hospitais públicos.

ABSTRACT

Ethnopharmacological and ethnobotanical approaches are described in the literature as efficient to identify plants of interest for phytochemical and pharmacological studies. In the present work, we reflect on the quality of the data collected in ethno-directed studies. In accordance to the problems identified in published studies, and their theoretical and methodological underpinnings, we believe that these studies are poorly suited to contribute to the advancement of research aimed at the development of novel drugs.

ABSTRACT

OBJECTIVE: To determine the incidence of Mycobacterium tuberculosis complex and non-tuberculous mycobacterial isolates in the routine setting of a large general hospital using an "in-house" multiplex polymerase chain reaction method and to establish a paradigm for the definitive identification of mycobacteria isolated using semi-automated equipment. METHODS: Established tests, including polymerase chain reaction restriction enzyme analysis, PNB, and NAP inhibition tests as the gold standard, showed 100% agreement with an IS6110/hsp65 multiplex polymerase chain reaction when used to identify stock strains (n = 117). RESULTS: In a subsequent study, 8,790 clinical specimens producing 476 isolates were evaluated with multiplex PCR and also showed 100% agreement in identification using PRA-polymerase chain reaction as the gold standard. The application of this technique to routine analysis was demonstrated in this study. A method was established with the initial application of multiplex PCR for all positive liquid cultures and the subsequent identification of non-tuberculous mycobacteria by polymerase chain reaction restriction enzyme analysis. In total, 77% of isolates belonged to the Mycobacterium tuberculosis complex, and 23% were non-tuberculous mycobacteria. CONCLUSIONS: Several non-tuberculous mycobacterial species were identified, primarily M. avium, but other potentially pathogenic species were also frequently observed, including M. fortuitum, M. abscessus, and M. kansasii. The expeditious communication of these data to the clinical staff was fundamental for the diagnosis of clinical cases. Even in settings where tuberculosis is of major importance, the incidence of non-tuberculous mycobacteria infection is substantial.

ABSTRACT

Objetivo. Avaliar a capacidade de selamento e a adaptação de intermediários UCLA, com ou sem uma cinta de cobalto-cromo (CoCr), em um sistema de implante de hexágono externo. Materiais e métodos. 120 implantes hexágono externo (Sistema de Implante Nacional - SIN, SP, Brazil) foram dividos em dois grupos (n=60) para receber intermediários UCLA de 6 fabricantes (n=10), com ou sem cinta pré-fabricada de CoCr (n=60). Os intermediários foram fundidos e subdivididos em 12 grupos da seguinte forma: M (Microplant), I (Impladen), S (SIN), Sv (Signo Vinces), T (TitaniumFix), and B (Bionnovation). A capacidade de selamento foi determinada pela colocação de 0.7 μL de azul de toluidina, 0.1% (TB) no espaço interno dos implantes antes do torque nos intermediários. Os espécimes implante-intemediários foram colocados dentro de tubos de 2.0 mL, contendo 0.7 mL de água destilada, a fim de manter a interface implante-intemediário submersa. Amostras de 100 μl foram coletadas após 1, 3, 6, 24, 48, 72, 96 e 144 horas de incubação para medição da absorbância em um espectofotômetro e devolvidos para medidas subsequentes. Para análise estatística, foram empregados o teste ANOVA a dois critérios (p < 0.05) e o teste de Tukey. Microscopia eletrônica de varredura (MEV) foi usado para visualização da adaptação da interface implante-intermediário. Resultados. Os grupos M, Sv, e T sem cinta CoCr apresentaram completa liberação de corante (TB) em 1 h, enquanto que nos grupos I, S, e B, a liberação do corante ocorreu em 3, 24 e 96 h, respectivamente. Para os intermediários com cinta préfabricada, a completa liberação de corante ocorreu em 6 h para o grupo S, em 24 h para os grupos Sv, T e B, e em 72 h para os grupos M e I. Foram observados desajustes na interface implante/intermediário em todos os grupos. Os desajustes mais evidentes foram observados para os grupos M e T, sem cinta de CoCr. Conclusões. A completa liberação de corante foi observada em diferentes períodos de...


To evaluate the effect of the presence of a prefabricated cobalt-chromium (CoCr) margin in a universal castable long abutment (UCLA) in the sealing capability and fit of the implant-abutment mating zone. Materials andmethods. One-hundred and twenty external hexagon implants (SIN, SP, Brazil) were divided in two groups (n=60 each) to receive UCLA abutments from 6 manufacturers (n=10 each) either with or without a CoCr margin (n=60 each). Abutments were cast and 12 groups were formed and named as: M (Microplant), I (Impladen), S (SIN), Sv (Signo Vinces), T (TitaniumFix), and B (Bionnovation). Sealing was determined by placing 0.7 μL of 0.1% toluidine blue (TB) in the implant wells before abutment torquing. Implant-abutment samples were placed into 2.0 mL vials containing 0.7 mL of distilled water to maintain the implant-abutment interface submerged. Aliquots of 100 μl of water were retrieved at 1, 3, 6, 24, 48, 72, 96 and 144 hours incubation times for absorbance measurement in a spectrophotometer, and returned for repeated measurements. Two-way ANOVA (p < 0.05) and Tukey's test were used. Scanning electron microscopy (SEM) was used for observation of the implant-abutment fit. Results. Groups M, Sv, and T without the CoCr margin resulted in complete release of TB at 1 h, whereas I, S, and B did at 3, 24 and 96 h, respectively. Complete leakage in abutments with the prefabricated marginoccurredat 6 h for S, 24 h for Sv, T and B, and 72 h for M and I. Implant/abutment gaps were observed in all groups. A poorer fit was depicted for groups M and T without the CoCr margin. Conclusions. Complete leakage was observed for all UCLA abutments regardless of the presence of the CoCrmargin. Implant-abutment gaps was observed for all groups.

Assistência ambulatorial pode ser definida como modalidade de atuação realizada por um ou mais integrantes da equipe de saúde a pacientes em regime de não internação, com conjunto de ações delimitado. Com o objetivo de dimensionar os recursos necessários para a assistência ambulatorial em um hospital público universitário estadual de grande porte, localizado no município de São Paulo, foi desenvolvida metodologia específica. A metodologia envolveu coleta retrospectiva de dados a partir da observação da cooperação in loco, sendo aplicada aos ambulatórios de 27 especialidades médicas, durante os meses de abril, maio e junho de 2011. Foram utilizadas informações relacionadas a consultas ofertadas, agendadas e realizadas, além de informações relacionadas ao período pós consulta. Os seguintes indicadores relacionados a consultas foram propostos: relação consulta seguimento/nova, relação matrículas/alta e altas em consultas novas. Foram propostos também mecanismos para cálculo de tempo médio de permanência do paciente no ambulatório e tempo médio de atendimento. Para a projeção de horas-sala necessárias a cada especialidade, é proposta uma relação entre horas-sala de ambulatórios utilizadas e horas-sala de ambulatórios disponíveis. Finalmente, são propostos indicadores para cálculo do número de consultórios necessários para atender a produção da clínica analisada, número de médicos necessários nos ambulatórios de especialidades cirúrgicas e número de médicos necessários nos ambulatórios de especialidades clínicas.
