RESUMO

Infectious diseases affecting habitat-forming species can have significant impacts on population dynamics and alter the structure and functioning of marine ecosystems. Recently, a fungal infection was described as the causative agent of necrotic lesions on the stipe of the forest-forming macroalga Phyllospora comosa, a disease named "stipe rot" (SR). Here, we developed a quantitative PCR (qPCR) method for rapid detection and quantification of this pathogen, which was applied to evaluate the level of SR infection in eight P. comosa populations spanning the entire latitudinal distribution of this species along southeastern Australia. We also investigated the relationship between the abundance and prevalence of Stipe Rot Fungus (SRF) and potential host chemical defenses as well as its relationship with morphological and ecophysiological traits of P. comosa. qPCR estimates of SRF abundance reflected the levels of infection estimated by visual assessment, with higher numbers of SRF copies being observed in individuals showing high or intermediate levels of visual symptoms of SR. Concordance of conventional PCR and visual assessments was 92 and 94%, respectively, compared to qPCR detection. SRF prevalence was positively related to fucoxanthin content and herbivory, but not significant related to other traits measured (phlorotannin content, total length, thallus diameter, stipe width, number of branches, frond width, fouling, bleaching, gender, and photosynthetic efficiency). These results provide confidence for previous reports of this disease based upon visual assessments only, contribute to the development of monitoring and conservation strategies for safeguarding P. comosa forests, and generate insights into potential factors influencing host-pathogen interactions in this system.

RESUMO

OBJETIVO: Investigar as funções neuropsicológicas perceptuais visomotoras de crianças com fissura labiopalatina. MÉTODOS: Estudo observacional, prospectivo, transversal, descritivo, realizado em um hospital de referência para anomalias craniofaciais no período de agosto/2012 a fevereiro/2013. Participaram 50 crianças de ambos os sexos, 25 com fissura labiopalatina compondo o GI e 25 como grupo controle, GII, com idade de 10 anos. Utilizaram-se para a avaliação os testes Matrizes Progressivas Coloridas, Gestáltico Visomotor e as subprovas de Exame Neuropsicológico, seguidos de aplicação estatística, utilizando-se testes de promoção e correlação (Fischer) ao nível de significância de 5%. RESULTADOS: O grupo com fissura labiopalatina demonstrou desempenhos abaixo da média esperada para a idade, sendo o grupo com o tipo transforame labial o mais prejudicado na performance da competência perceptual visomotora. Os tipos de fissura pré e pós-forame obtiveram escores na média, com pontuações pareadas ao grupo controle. CONCLUSÃO: As crianças com fissura labiopalatina do tipo transforame mostraram-se mais vulneráveis a alterações nas funções visomotoras. Além disso, as habilidades nos domínios perceptivos construtivos estão relacionadas a desempenhos classificados abaixo da média esperada para a faixa etária na população-alvo

OBJECTIVE: To investigate the neuropsychological visual motor perceptual functions of children with cleft lip and palate. METHODS: Observational, prospective, cross-sectional, descriptive study, held at a referral hospital for craniofacial anomalies in the period from August 2012 to February 2013. The study included 50 children of both sexes, 25 of them with cleft lip and palate, comprising GI, and 25 children as control group, GII, aged 10 years. For evaluation, the study applied the Coloured Progressive Matrices, the Visual Motor Gestalt Test, and Neuropsychological Subtests Examination, followed by statistical evaluation, using promotion and correlation tests (Fischer) at 5% significance level. RESULTS: The group with cleft lip and palate showed performance below the expected average for their age, the group with the trans-incisive foramen cleft type being the most affected in the performance of visual motor perceptual competence. Pre- and post-foramen cleft types obtained average scores, with values matching the control group. CONCLUSION: Children with cleft lip and palate of trans-foramen type were found more liable to present disorders in visual motor functions. Furthermore, skills in the perceptual and constructive domains are related to performances classified below the expected mean for the age range in the target population

RESUMO

Background: Several studies have shown that Tai Chi Chuan can improve cardiac function in patients with heart disease. Objective: To conduct a systematic review of the literature to assess the effects of Tai Chi Chuan on cardiac rehabilitation for patients with coronary artery disease. Methods: We performed a search for studies published in English, Portuguese and Spanish in the following databases: MEDLINE, EMBASE, LILACS and Cochrane Register of Controlled Trials. Data were extracted in a standardized manner by three independent investigators, who were responsible for assessing the methodological quality of the manuscripts. Results: The initial search found 201 studies that, after review of titles and abstracts, resulted in a selection of 12 manuscripts. They were fully analyzed and of these, nine were excluded. As a final result, three randomized controlled trials remained. The studies analyzed in this systematic review included patients with a confirmed diagnosis of coronary artery disease, all were clinically stable and able to exercise. The three experiments had a control group that practiced structured exercise training or received counseling for exercise. Follow-up ranged from 2 to 12 months. Conclusion: Preliminary evidence suggests that Tai Chi Chuan can be an unconventional form of cardiac rehabilitation, being an adjunctive therapy in the treatment of patients with stable coronary artery disease. However, the methodological quality of the included articles and the small sample sizes clearly indicate that new randomized controlled trials are needed in this regard. .

Fundamento: Alguns estudos têm mostrado que o Tai Chi Chuan pode melhorar a função cardiorrespiratória de pacientes com doenças cardíacas. Objetivo: Realizar uma revisão sistemática da literatura para avaliar os efeitos do Tai Chi Chuan na reabilitação cardíaca de pacientes com doença arterial coronária. Métodos: Foi realizada uma pesquisa nas seguintes bases de dados: MEDLINE, EMBASE, LILACS e Registro Cochrane de Ensaios Controlados. Foram feitas buscas por estudos publicados em inglês, português e espanhol. Os dados foram extraídos de forma padronizada, por três investigadores independentes, que foram responsáveis pela avaliação da qualidade metodológica dos manuscritos. Resultados: A busca inicial detectou 201 estudos que, após revisão de títulos e resumos, resultou na seleção de 12 manuscritos. Os mesmos foram analisados na íntegra e, destes, nove foram excluídos. Ao final, restaram três ensaios clínicos randomizados. Os estudos incluídos nessa revisão sistemática foram compostos por amostra de pacientes com diagnóstico comprovado de doença arterial coronária, todos estáveis clinicamente e capazes de se exercitar. Os três experimentos contaram com a presença de um grupo controle praticante de qualquer categoria de treinamento físico estruturado ou receberam aconselhamento para exercício físico. O tempo de acompanhamento variou de 2 a 12 meses. Conclusão: Evidências preliminares sugerem que o Tai Chi Chuan possa ser uma forma não convencional de reabilitação cardíaca, podendo ser terapêutica adjuvante no tratamento de pacientes com doença arterial coronária estável. No entanto, a qualidade metodológica dos artigos incluídos e as amostras de tamanho reduzido ...

RESUMO

Dentre as profissões da área da saúde, a enfermagem, em particular, tem sido afetada pelos distúrbios musculoesqueléticos produzindo alterações na vida desses trabalhadores, impossibilitando-os de realizarem atividades cotidianas e laborais. Objetivo: Investigar a prevalência de dor osteomuscular e a associação com a qualidade de vida em profissionais de enfermagem que atuam em equipes de cirurgia no Hospital de Clínicas de Porto Alegre. Método: Estudo transversal realizado entre março de 2011 ejaneiro de 2012, em um hospital universitário terciário do sul do Brasil. Foram avaliados 110 trabalhadores de enfermagem das equipes de cirurgia. Foram excluídos os trabalhadores em licença saúde, fériasou outro tipo de afastamento durante o período de coleta dos dados. A dor osteomuscular foi avaliada através do questionário Nórdico de Sintomas Osteomusculares e a qualidade de vida foi avaliada atravésdo questionário Medical Outcomes Study 36 - Item Short-Form Survey (SF-36). As relações entre dor osteomuscular e qualidade de vida foram analisadas através do Teste U de Mann-Whitney, utilizandonível de significância de 95%. Resultados: A prevalência de dor osteomuscular encontrada neste estudo foi de 91,81%. Com relação às regiões anatômicas, considerou-se as queixas de dor osteomuscular retroativo há doze meses, onde o predomínio foi de dor no pescoço (56%) e ombros (56%). Quando consideramos afastamento por dor osteomuscular encontramos a prevalência de dor lombar (34%). O grupo que não relatou dor osteomuscular apresentou melhores índices de qualidade de vida nos domínios de capacidade funcional, aspectos físicos, dor, vitalidade, aspectos sociais e saúde mental. Conclusão: A dor osteomuscular apresenta maior prevalência nas regiões do pescoço e ombros. Além disso, o maior número de afastamentos ocorre por prevalência de dor lombar entre os trabalhadores de enfermagem das equipes de cirurgia. A dor influenciou na qualidade de vida afetando seis dos domínios avaliados

Among the health professions, nursing, in particular, has been affected by musculoskeletal disorders. The WMSD produce changes in the lives of these workers, impossible of them held daily activities andlabour. Objective: Investigating the prevalence of musculoskeletal pain and associated with the quality of life in nursing professionals who work in surgery teams. Method: Cross-sectional study conductedbetween March 2011 and January 2012 in a tertiary university hospital in southern Brazil. We evaluated 110 workers nursing teams. It was excluded workers on sick leave, vacation or other absence duringthe period of data collection. The musculoskeletal pain was assessed using the Nordic Musculoskeletal symptoms questionnaire the quality of life was assessed by the Medical Outcomes Study 36 - Item Short-Form Survey (SF-36). The relationship between musculoskeletal pain and quality of life were analyzed by the U of Mann-Whitney test, using a significance level of 95%. Results: The prevalence of musculoskeletal pain found in this study was 91.81%. With respect to anatomic regions, it was consideredthe complaints of musculoskeletal pain retroactive twelve months ago, where there was the predominance of neck pain (56%) and shoulders (56%). When we consider sick leaving for musculoskeletal painwe found the prevalence of low back pain (34%). The group who reported no musculoskeletal pain showed better indices of quality of life in the areas of physical functioning, physical aspect, bodily pain,vitality, social and mental health aspect. Conclusion: the higher prevalence of musculoskeletal pain in the neck and shoulder regions. Moreover, the largest number of sick leaves occurs because of the prevalenceof low back pain among nursing staff of the surgical teams. The pain influenced the quality of life affecting six of the areas assessed.

RESUMO

OBEJTIVO: avaliar o nível de desenvolvimento cognitivo e afetivo-social de crianças com diagnóstico de deficiência auditiva. MÉTODO: participaram do estudo 50 crianças com diagnóstico de deficiência auditiva, com idade média de 16,1 meses, de ambos os gêneros. Empregou-se a entrevista semi-estruturada com os pais para a obtenção da história de vida da criança, a Escala de Desenvolvimento Comportamental e a Escala de Avaliação da Reação de Retração do Bebê. RESULTADO: o estudo identificou 80% das crianças com perda auditiva profunda bilateral. O Quociente de Desenvolvimento na normalidade ocorreu em 76% da amostra, sendo as funções da linguagem e pessoal-social, as mais prejudicadas. Os níveis de ajustamento afetivo e interacional foram caracterizados pelas reações de alarme para problemas de interação pessoal-social. CONCLUSÃO: as competências defasadas de habilidades verbais e não-verbais mostraram implicações no desenvolvimento cognitivo, sugestivas da condição da criança com perda auditiva e dos fatores de risco associados, com limitação circunstancial a trocas comunicativas que promovem o desenvolvimento de competências adaptativas e o fortalecimento da auto-estima para as relações.

PURPOSE: the objective of this study was to evaluate the level of cognitive, affective and social development of children diagnosed with hearing loss. METHOD: the study included 50 children diagnosed with hearing loss, with a mean age of 16.1 months, both genders. We applied a semi-structured interview with parents for the life history of the child, Scale Development and Behavioral Assessment Scale Reaction Baby Retraction. RESULTS: the study identified 80% of children with bilateral profound hearing loss. Quotient of normal development occurred in 76% of the sample and the most affected functions were language and personal-social. The affective and interactional levels adjustment were characterized by the alarm reactions for personal problems and social interaction. CONCLUSION: the dephased verbal and nonverbal competences showed implications on cognitive development, suggesting the hearing loss condition and associated risk factors, with limited situational communicative exchanges that promote the development of adaptive skills and increased the self-esteem on the relationships.
