Pacientes com transtornos relacionados ao uso de substâncias psicoativas atendidos em uma unidade de emergência psiquiátrica

Study type: Prevalence study. Objective: To describe the socio demographic and clinical profile of patients with mental and behavioral disorders due to psychoactive substance (PAS) use, evaluated by the Psychiatric team of the Referenced Emergency Unit (REU) at the State University Clinical Hospital of Campinas (UNICAMP-HC). Methods and casuistic: This is a descriptive and quantitative study, which analyzed patients with mental and behavioral disorders due to PAS use, evaluated by the Psychiatric team of the REU-HC-UNICAMP during a period of 12 months, starting on May 2010. Results: There were evaluated 350 patients with PAS related disorders, representing 23.8% of those who sought psychiatric care. Most were males and younger than other patients of the emergency unit. The main reason for seeking help was psychiatric complaint other than PAS related disorders (23.1%), followed by desire to be treated oneself/being admitted to inpatient psychiatric treatment (20.8%) and intoxication (12.5%); 38.5% had a diagnosis of multiple PAS dependence and 34.8% were diagnosed with isolated alcohol dependence; 36% had psychiatric comorbidities and, when compared to other patients, they received more medications during attendance and were less directed to primary care units. Conclusion: There is a high rate of consultations of patients with PAS related problems in the psychiatric emergency unit. Data on the profile of the evaluated these patients can contribute to the improvement of care to this populationModelo do Estudo: Estudo de prevalência.

Hazardous use of alcohol among undergraduate students at a public university

Background The potentially harmful consequences of alcohol use among undergraduates have become a growing concern in recent years. Objectives This study aimed to determine the prevalence of hazardous use of alcohol in this population and to identify demographic and psychosocial factors associated with this pattern of consumption. Methods This was a cross-sectional study using an anonymous and self-completed questionnaire in the classroom. The questionnaire was administered to 1,290 enrolled male and female students, which comprised a proportional sample of the main areas of knowledge at University of Campinas. The questionnaire produced sociodemographic and psychosocial profiles and the Alcohol Use Disorders Identification Test was used to detect hazardous use of alcohol. Results The prevalence of hazardous use of alcohol among the study participants was 24%. Male gender, subjective perceived social support in case of difficulties, being sexually active, not dating, having smoked tobacco cigarettes or marijuana, and having used other illicit psychoactive substances were associated with hazardous use of alcohol. Discussion Variables related to gender, sexuality, affective partnerships, and consumption of other psychoactive substances were associated with hazardous use of alcohol, which was identified in a quarter of the evaluated students, and indicate the need for strategies to prevent and to treat problems

Isolation and enzyme bioprospection of endopytic bacteria associated with plants of Brazilian mangrove ecosystem

The mangrove ecosystem is a coastal tropical biome located in the transition zone between land and sea that is characterized by periodic flooding, which confers unique and specific environmental conditions on this biome. In these ecosystems, the vegetation is dominated by a particular group of plant species that provide a unique environment harboring diverse groups of microorganisms, including the endophytic microorganisms that are the focus of this study. Because of their intimate association with plants, endophytic microorganisms could be explored for biotechnologically significant products, such as enzymes, proteins, antibiotics and others. Here, we isolated endophytic microorganisms from two mangrove species, Rhizophora mangle and Avicennia nitida, that are found in streams in two mangrove systems in Bertioga and Cananéia, Brazil. Bacillus was the most frequently isolated genus, comprising 42% of the species isolated from Cananéia and 28% of the species from Bertioga. However, other common endophytic genera such as Pantoea, Curtobacterium and Enterobacter were also found. After identifying the isolates, the bacterial communities were evaluated for enzyme production. Protease activity was observed in 75% of the isolates, while endoglucanase activity occurred in 62% of the isolates. Bacillus showed the highest activity rates for amylase and esterase and endoglucanase. To our knowledge, this is the first reported diversity analysis performed on endophytic bacteria obtained from the branches of mangrove trees and the first overview of the specific enzymes produced by different bacterial genera. This work contributes to our knowledge of the microorganisms and enzymes present in mangrove ecosystems

Avian influenza virus (H11N9) in migratory shorebirds wintering in the Amazon region, Brazil

Aquatic birds are the natural reservoir for avian influenza viruses (AIV). Habitats in Brazil provide stopover and wintering sites for water birds that migrate between North and South America. The current study was conducted to elucidate the possibility of the transport of influenza A viruses by birds that migrate annually between the Northern and Southern Hemispheres. In total, 556 orotracheal/cloacal swab samples were collected for influenza A virus screening using real-time RT-PCR (rRT-PCR). The influenza A virus-positive samples were subjected to viral isolation. Four samples were positive for the influenza A matrix gene by rRT-PCR. From these samples, three viruses were isolated, sequenced and characterized. All positive samples originated from a single bird species, the ruddy turnstone (Arenaria interpres), that was caught in the Amazon region at Caeté Bay, Northeast Pará, at Ilha de Canelas. To our knowledge, this is the first isolation of H11N9 in the ruddy turnstone in South America. (Résumé d'auteur

Oral delivery of fish oil in oil-in-water nanoemulsion : development, colloidal stability and modulatory effect on in vivo inflammatory induction in mice

To improve the oral absorption of fish oil and test its anti-inflammatory effect, a fish oil nanoemulsion was developed using cis-4,7,10,13,16,19-docosahexaenoic fatty acid as a biomarker for oral administration. The colloidal stability tests of the fish oil nanoemulsion showed an average size of 155.44 nm ± 6.46 (4 °C); 163.04 nm ± 9.97 (25 °C) and polydispersity index 0.22 ± 0.02 (4 °C), 0.21 ± 0.02 (25 °C), indicating systems with low polydispersity and stable droplets. The fish oil nanoemulsion did not alter the cell viability of the RAW 264.7 macrophages and, at a concentration of 0.024 mg/mL, was kinetically incorporated into the cells after 18 h of contact. The nanoemulsion was maintained in the gastrointestinal region for a significantly shorter period of time (p ≤ 0.05) compared to the intake of fish oil in free form. Inflammatory tests demonstrated that nanoemulsion and fish oil showed less (p ≤ 0.05) neutrophil infiltration after 24h of sepsis induction and there was a significant reduction (p ≤ 0.05) in the volume of paw edema in female adult Balb/c mice who received the nanoemulsion diet compared to the other experimental groups (control, formalin, fish oil and sunflower oil). These results indicate that the fish oil nanoemulsion was significantly effective in the dietary conditions tested here, presenting satisfactory responses in the modulation of inflammatory disorders, demonstrating interesting and beneficial nutraceutical effects

Determinants of intensive insulin therapeutic regimens in patients with type 1 diabetes: data from a nationwide multicenter survey in Brazil

Background: To evaluate the determinants of intensive insulin regimens (ITs) in patients with type 1 diabetes (T1D).Methods: This multicenter study was conducted between December 2008 and December 2010 in 28 public clinics in 20 Brazilian cities. Data were obtained from 3,591 patients (56.0% female, 57.1% Caucasian). Insulin regimens were classified as follows: group 1, conventional therapy (CT) (intermediate human insulin, one to two injections daily); group 2 (three or more insulin injections of intermediate plus regular human insulin); group 3 (three or more insulin injections of intermediate human insulin plus short-acting insulin analogues); group 4, basal-bolus (one or two insulin injections of long-acting plus short-acting insulin analogues or regular insulin); and group 5, basal-bolus with continuous subcutaneous insulin infusion (CSII). Groups 2 to 5 were considered IT groups.Results: We obtained complete data from 2,961 patients. Combined intermediate plus regular human insulin was the most used therapeutic regimen. CSII was used by 37 (1.2%) patients and IT by 2,669 (90.2%) patients. More patients on IT performed self-monitoring of blood glucose and were treated at the tertiary care level compared to CT patients (p < 0.001). the majority of patients from all groups had HbA1c levels above the target. Overweight or obesity was not associated with insulin regimen. Logistic regression analysis showed that economic status, age, ethnicity, and level of care were associated with IT (p < 0.001).Conclusions: Given the prevalence of intensive treatment for T1D in Brazil, more effective therapeutic strategies are needed for long term-health benefits.Farmanguinhos/Fundacao Oswaldo Cruz/National Health MinistryBrazilian Diabetes SocietyFundacao do Amparo a Pesquisa do Estado do Rio de JaneiroConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Univ Estado Rio de Janeiro, Unit Diabet, BR-20551030 Rio de Janeiro, BrazilBaurus Diabet Assoc, São Paulo, BrazilFed Univ São Paulo State, Diabet Unit, São Paulo, BrazilFed Univ Hosp Porto Alegre, Porto Alegre, BrazilUniv Hosp São Paulo, Diabet Unit, São Paulo, BrazilUniv Fed Rio de Janeiro, Rio de Janeiro, BrazilUniv Fed Ceara, Fortaleza, Ceara, BrazilSanta Casa Misericordia, Belo Horizonte, MG, BrazilSanta Casa Misericordia São Paulo, São Paulo, BrazilUniv Fed Amazonas, Manaus, Amazonas, BrazilHosp Geral de Bonsucesso, Rio de Janeiro, BrazilHosp Univ Clementino Fraga Filho IPPMG, Rio de Janeiro, BrazilUniv Hosp São Paulo, São Paulo, BrazilFac Ciencias Med Santa Casa São Paulo, São Paulo, BrazilUniv São Paulo, Inst Crianca, Hosp Clin, São Paulo, BrazilUniv São Paulo, Fac Med Ribeirao Preto, Hosp Clin, Ribeirao Preto, BrazilAmbulatorio Fac Estadual Med Sao Jose Rio Preto, Ribeirao Preto, BrazilEscola Paulista Med, Ctr Diabet, Ribeirao Preto, BrazilClin Endocrinol Santa Casa Belo Horizonte, Belo Horizonte, MG, BrazilUniv Estadual Londrina, Londrina, BrazilUniv Fed Parana, Hosp Clin, Porto Alegre, RS, BrazilInst Crianca Com Diabet Rio Grande Sul, Rio Grande Do Sul, RS, BrazilGrp Hosp Conceicao, Inst Crianca Com Diabet, Porto Alegre, RS, BrazilHosp Univ Santa Catarina, Florianopolis, SC, BrazilInst Diabet Endocrinol Joinville, Joinville, BrazilHosp Reg Taguatinga, Brasilia, DF, BrazilHosp Geral Goiania, Goiania, Go, BrazilCtr Diabet & Endocrinol Estado Bahia, Goiania, Go, BrazilUniv Fed Maranhao, Sao Luis, BrazilCtr Integrado Diabet & Hipertensao Ceara, Fortaleza, Ceara, BrazilUniv Fed Sergipe, Aracaju, BrazilHosp Univ Alcides Carneiro, Campina Grande, BrazilHosp Univ Joao de Barros Barreto, Belem, Para, BrazilFed Univ São Paulo State, Diabet Unit, São Paulo, BrazilUniv Hosp São Paulo, Diabet Unit, São Paulo, BrazilUniv Hosp São Paulo, São Paulo, BrazilEscola Paulista Med, Ctr Diabet, Ribeirao Preto, BrazilWeb of Scienc

A diversidade em sala de aula e a relação professor-aluno

O presente estudo teve como objetivo identificar as percepções de professores quanto à relação professor-aluno, a partir da aplicação da Escala de Relacionamento Professor-Aluno, versão reduzida e traduzida da Student-Teacher Relationship Scale, relacionando seus domínios a características dos discentes, no que tange às variáveis necessidade educacional especial, sexo, cor/raça, série e idade. Na pesquisa, 21 professoras regentes de seis escolas públicas da cidade de Juiz de Fora, no estado de Minas Gerais, avaliaram a relação que mantêm com todos os discentes de suas turmas, perfazendo um total de 495 escalas referentes a estudantes de salas-alvo, do primeiro ao quinto ano do Ensino Fundamental. Constatou-se que a relação professor-aluno é mais conflituosa e menos positiva quando se trata de discentes do sexo masculino e com necessidade educacional especial. Observou-se uma relação mais positiva com estudantes nos anos iniciais de escolarização, e mais negativa quanto mais velho fosse o aluno. Estudos adicionais são recomendados
