The 2005 National Institutes of Health (NIH) Consensus Conference proposed new criteria for diagnosing and scoring the severity of chronic graft-versus-host disease (GVHD). The 2014 NIH consensus maintains the framework of the prior consensus with further refinement based on new evidence. Revisions have been made to address areas of controversy or confusion, such as the overlap chronic GVHD subcategory and the distinction between active disease and past tissue damage. Diagnostic criteria for involvement of mouth, eyes, genitalia, and lungs have been revised. Categories of chronic GVHD should be defined in ways that indicate prognosis, guide treatment, and define eligibility for clinical trials. Revisions have been made to focus attention on the causes of organ-specific abnormalities. Attribution of organ-specific abnormalities to chronic GVHD has been addressed. This paradigm shift provides greater specificity and more accurately measures the global burden of disease attributed to GVHD, and it will facilitate biomarker association studies.

To develop recommendations for the diagnosis, management and treatment of lupus nephritis in Brazil. Extensive literature review with a selection of papers based on the strength of scientific evidence and opinion of the Commission on Systemic Lupus Erythematosus members, Brazilian Society of Rheumatology. 1) Renal biopsy should be performed whenever possible and if this procedure is indicated; and, when the procedure is not possible, the treatment should be guided with the inference of histologic class. 2) Ideally, measures and precautions should be implemented before starting treatment, with emphasis on attention to the risk of infection. 3) Risks and benefits of treatment should be shared with the patient and his/her family. 4) The use of hydroxychloroquine (preferably) or chloroquine diphosphate is recommended for all patients (unless contraindicated) during induction and maintenance phases. 5) The evaluation of the effectiveness of treatment should be made with objective criteria of response (complete remission/partial remission/refractoriness). 6) ACE inhibitors and/or ARBs are recommended as antiproteinuric agents for all patients (unless contraindicated). 7) The identification of clinical and/or laboratory signs suggestive of proliferative or membranous glomerulonephritis should indicate an immediate implementation of specific therapy, including steroids and an immunosuppressive agent, even though histological confirmation is not possible. 8) Immunosuppressives must be used during at least 36 months, but these medications can be kept for longer periods. Its discontinuation should only be done when the patient achieve and maintain a sustained and complete remission. 9) Lupus nephritis should be considered as refractory when a full or partial remission is not achieved after 12 months of an appropriate treatment, when a new renal biopsy should be considered to assist in identifying the cause of refractoriness and in the therapeutic decision.

OBJECTIVES: It is well known that the efficacy and the efficiency of a Class II malocclusion treatment are aspects closely related to the severity of the dental anteroposterior discrepancy. Even though, sample selection based on cephalometric variables without considering the severity of the occlusal anteroposterior discrepancy is still common in current papers. In some of them, when occlusal parameters are chosen, the severity is often neglected. The purpose of this study is to verify the importance given to the classification of Class II malocclusion, based on the criteria used for sample selection in a great number of papers published in the orthodontic journal with the highest impact factor. MATERIAL AND METHODS: A search was performed in PubMed database for full-text research papers referencing Class II malocclusion in the history of the American Journal of Orthodontics and Dentofacial Orthopedics (AJO-DO). RESULTS: A total of 359 papers were retrieved, among which only 72 (20.06%) papers described the occlusal severity of the Class II malocclusion sample. In the other 287 (79.94%) papers that did not specify the anteroposterior discrepancy severity, description was considered to be crucial in 159 (55.40%) of them. CONCLUSIONS: Omission in describing the occlusal severity demands a cautious interpretation of 44.29% of the papers retrieved in this study.

The aim of this study was to determine how abiotic factors drive the phytoplankton community in a water supply reservoir within short sampling intervals. Samples were collected at the subsurface (0.1 m) and bottom of limnetic (8 m) and littoral (2 m) zones in both the dry and rainy seasons. The following abiotic variables were analyzed: water temperature, dissolved oxygen, electrical conductivity, total dissolved solids, turbidity, pH, total nitrogen, nitrite, nitrate, total phosphorus, total dissolved phosphorus and orthophosphate. Phytoplankton biomass was determined from biovolume values. The role abiotic variables play in the dynamics of phytoplankton species was determined by means of Canonical Correspondence Analysis. Algae biomass ranged from 1.17×10(4) to 9.21×10(4) µg.L-1; cyanobacteria had biomass values ranging from 1.07×10(4) to 8.21×10(4) µg.L-1. High availability of phosphorous, nitrogen limitation, alkaline pH and thermal stability all favored cyanobacteria blooms, particularly during the dry season. Temperature, pH, total phosphorous and turbidity were key factors in characterizing the phytoplankton community between sampling times and stations. Of the species studied, Cylindrospermopsis raciborskii populations were dominant in the phytoplankton in both the dry and rainy seasons. We conclude that the phytoplankton was strongly influenced by abiotic variables, particularly in relation to seasonal distribution patterns.

Therapeutic failure of benznidazole (BZ) is widely documented in Chagas disease and has been primarily associated with variations in the drug susceptibility of Trypanosoma cruzi strains. In humans, therapeutic success has been assessed by the negativation of anti-T. cruzi antibodies, a process that may take up to 10 years. A protocol for early screening of the drug resistance of infective strains would be valuable for orienting physicians towards alternative therapies, with a combination of existing drugs or new anti-T. cruzi agents. We developed a procedure that couples the isolation of parasites by haemoculture with quantification of BZ susceptibility in the resultant epimastigote forms. BZ activity was standardized with reference strains, which showed IC50 to BZ between 7.6-32 µM. The assay was then applied to isolates from seven chronic patients prior to administration of BZ therapy. The IC50 of the strains varied from 15.6 ± 3-51.4 ± 1 µM. Comparison of BZ susceptibility of the pre-treatment isolates of patients considered cured by several criteria and of non-cured patients indicates that the assay does not predict therapeutic outcome. A two-fold increase in BZ resistance in the post-treatment isolates of two patients was verified. Based on the profile of nine microsatellite loci, sub-population selection in non-cured patients was ruled out.

OBJETIVO: Comparar duas abordagens baseadas em critérios do Quality Assessment of Diagnostic Accuracy Studies (QUADAS) e do Standards for Reporting Studies of Diagnostic Accuracy (STARD) na avaliação de qualidade de estudos de validação do teste rápido OptiMal®, para diagnóstico de malária. MÉTODOS: Foi realizada busca de artigos de validação do teste rápido na base bibliográfica Medline acessada pelo PubMed, no ano de 2007. Treze artigos foram recuperados na busca. Foram combinados 12 critérios do QUADAS e três do STARD para comparação com os critérios do QUADAS isoladamente. Foi considerado que artigos de regular a boa qualidade atenderiam pelo menos 50% dos critérios do QUADAS. RESULTADOS: Dos 13 artigos recuperados, 12 cumpriram pelo menos 50% dos critérios do QUADAS, e apenas dois atenderam à combinação dos critérios. Considerando-se a combinação dos dois critérios (> 6 QUADAS e > 3STARD), dois estudos (15,4%) apresentaram boa qualidade metodológica. A seleção de artigos usando a combinação proposta variou de dois a oito artigos, dependendo do número de itens considerados como ponto de corte. CONCLUSÕES: A combinação do QUADAS com o STARD tem o potencial de conferir maior rigor nas avaliações da qualidade de artigos publicados sobre validação de testes diagnósticos em malária, por incorporar a checagem de informações relevantes não alcançáveis pelo uso do QUADAS isoladamente.

OBJETIVO: realizar revisão sistemática de estudos de prevalência dos sintomas depressivos na perimenopausa.MÉTODO: A pesquisa foi efetuada a partir das bases de dados MEDLINE e EMBASE. Foram incluídos estudos transversais originais com populações adultas (idade de 40 a 55 anos), no período de 1996 a 2006, que estimaram a prevalência de sintomas depressivos na perimenopausa nos idiomas: inglês, francês, espanhol e português. A seleção dos estudos pela estratégia de busca foi feita de forma independente por dois avaliadores. Foram incluídos os estudos que preencheram os seguintes critérios metodológicos: características epidemiológicas, definições de perimenopausa, instrumentos válidos utilizados para sintomas depressivos.RESULTADOS: Após a avaliação de 1.345 artigos, restaram apenas cinco que caracterizaram uma população de 11.020 mulheres com idades entre 40 e 60 anos. Constatamos que a prevalência de sintomas depressivos na perimenopausa variou entre 19% e 73%.CONCLUSÃO: A presente revisão sistemática mostrou expressiva variação na prevalência de sintomas depressivos na perimenopausa; ademais, não foi possível caracterizar se a sintomatologia depressiva na perimenopausa decorreu exclusivamente de flutuações hormonais observadas neste estágio da vida ou de antecedentes prévios de depressão

Este artigo se propõe a analisar o tipo de relação que as Unidades de Saúde estabelecem com os adolescentes no município de Fortaleza, CE, na perspectiva da violência simbólica de Pierre Bourdieu. Para tanto, foram organizados seis grupos focais constituídos de profissionais das Unidades Básicas de Saúde da Família. O número de participantes variou de 10 a 15 pessoas. Os critérios de escolha das Unidades foram: aquelas que já realizaram algum projeto de promoção à saúde ou prevenção de doenças com adolescentes; que possuem profissionais que são reconhecidos por desenvolverem atendimento junto aos adolescentes. As falas do grupo foram anotadas e transcritas por um observador independente. O material coletado foi analisado de acordo com os critérios clássicos da análise de conteúdo. Os resultados mostraram que há uma descrença na implantação de políticas públicas para a saúde na adolescência e que a sustentabilidade de programas e projetos fica fragilizada pela ausência dessa estrutura de apoio às ações no cuidado aos adolescentes

Dados secundários de uma amostra aleatória de pré-escolares brasileiros foram analisados com o objetivo de avaliar a prevalência de desvios oclusais na dentição decídua, que podem adversamente afetar a dentição permanente, com base em critérios revisados. Overjet e overbite apresentaram pontos de corte descritos na literatura para a remoção dos casos de má oclusão leve. Overjet > 3mm e overbite > 3mm afetaram 16% e 7% das crianças, respectivamente. No plano sagital foram consideradas apenas as taxas de desvios bilaterais: relação molar em degrau distal (9,7%) e mesial (6,0%); relação dos caninos Classe 2 (11,0%) e Classe 3 (2,9%). Para os demais desvios não foram relatados na literatura critérios de severidade. Valores brutos de mordida aberta anterior (27,9%); mordida cruzada posterior (11,3%); apinhamento dentário maxilar (7,0%) e mandibular (11,3%) foram registrados. A avaliação da má oclusão na dentição decídua deve considerar a severidade dos desvios para a identificação de casos e não-casos de relevância em saúde pública. Enfatiza-se a necessidade de maior consenso e melhora na interpretação de dados epidemiológicos sobre a má oclusão nesse estágio de desenvolvimento

The investigation of the nature of motor difficulties children experiment resulted in the identification of a Developmental Coordination Disorder (DCD). The lack of consensus on the nature and the mechanisms of DCD might not be due to an apparent resilience of the disorder to the scientific enterprise. On the contrary, the present paper has a goal of presenting a thesis according to which the problem resides on the definition of DCD and on the selection of samples in studies that do not distinguish between clinical and research criteria. In conclusion, three steps for characterizing DCD are presented.

Grapholita molesta (Lepidoptera: Tortricidae) is one of the main pests of peach trees in Brazil, causing fruit losses of 3-5%. Among possible biological control agents, Trichogramma pretiosum (Hymenoptera: Trichogrammatidae) has been found in peach orchards. Our objectives were to study the rearing of T pretiosum in eggs of G. molesta and Anagasta kuehniella (Lepidoptera: Pyralidae), and select lineages of this parasitoid that have the potential to control G. molesta. Selection of best lineages was made from 5 populations of T pretiosum collected from organically-cultivated peach orchards. The study was done under controlled temperature (25 +/- 2 degrees C), relative humidity (70 +/- 10%) and 14:10 h (light:dark) photoperiod conditions. Grapholita molesta eggs were found to be adequate hosts for the development of T pretiosum, and the parameters for number of parasitized eggs, percent parasitized eggs, and sex ratio were similar to those for A. kuehniella eggs. The highest rate of parasitism of G. molesta eggs occurred in eggs with up to 48 h of embryonic development. Among the lineages of T pretiosum that were collected, HO8, PO8, PEL, and L3M showed the best biological performance and are therefore indicated for semi-field and field studies for biological control of oriental fruit moth.
