Respiratory system parameters in children with low severity cystic fibrosis: is there early involvement in relation to healthy peers? / Parâmetros do sistema respiratório em crianças com fibrose cística de baixa gravidade: há acometimento precoce em relação a pares saudáveis?

ABSTRACT Objective: To compare and analyze pulmonary function and respiratory mechanics parameters between healthy children and children with cystic fibrosis. Methods: This cross-sectional analytical study included healthy children (HSG) and children with cystic fibrosis (CFG), aged 6-13 years, from teaching institutions and a reference center for cystic fibrosis in Florianópolis/SC, Brazil. The patients were paired by age and sex. Initially, an anthropometric evaluation was undertaken to pair the sample characteristics in both groups; the medical records of CFG were consulted for bacterial colonization, genotype, and disease severity (Schwachman-Doershuk Score — SDS) data. Spirometry and impulse oscillometry were used to assess pulmonary function. Results: In total, 110 children were included, 55 in each group. In the CFG group, 58.2% were classified as excellent by SDS, 49.1% showed the ΔF508 heterozygotic genotype, and 67.3% were colonized by some pathogens. Statistical analysis revealed significant differences between both groups (p<0.05) in most pulmonary function parameters and respiratory mechanics. Conclusions: Children with cystic fibrosis showed obstructive ventilatory disorders and compromised peripheral airways compared with healthy children. These findings reinforce the early changes in pulmonary function and mechanics associated with this disease.

RESUMO Objetivo: Comparar e analisar parâmetros de função pulmonar e de mecânica respiratória entre escolares saudáveis e com fibrose cística (FC). Métodos: Estudo transversal que incluiu escolares saudáveis (GES) e com FC (GFC), com idades entre seis e 13 anos, provenientes de instituições de ensino e de um centro de referência da FC em Florianópolis/SC, Brasil, pareados por idade e sexo, respectivamente. Inicialmente, conduziu-se avaliação antropométrica para pareamento e caracterização de ambos os grupos e, no GFC, consultou-se prontuário médico para registro dos dados de colonização bacteriana, genótipo e gravidade da doença (Escore de Schwachman-Doershuk — ESD). Para a avaliação da função pulmonar, realizou-se espirometria e a avaliação da mecânica respiratória foi conduzida por meio do sistema de oscilometria de impulso. Resultados: Participaram 110 escolares, 55 em cada grupo. No GFC, 58,2% foram classificados pelo ESD como excelentes, 49,1% apresentaram genótipo ∆F508 heterozigoto e 67,3% eram colonizados por alguma patógeno. Houve diferença significativa (p<0,05) na maioria dos parâmetros de função pulmonar e de mecânica respiratória entre os grupos. Conclusões: Escolares com FC apresentaram distúrbio ventilatório obstrutivo e com comprometimento de vias aéreas periféricas, em comparação aos escolares hígidos. Esse evento reforça o início precoce da alteração de função pulmonar e de mecânica respiratória nessa enfermidade, evidenciados pelos achados desta investigação.

Genetic and clinical markers for predicting treatment responsiveness in rheumatoid arthritis / 医学前沿

Although many drugs and therapeutic strategies have been developed for rheumatoid arthritis (RA) treatment, numerous patients with RA fail to respond to currently available agents. In this review, we provide an overview of the complexity of this autoimmune disease by showing the rapidly increasing number of genes associated with RA.We then systematically review various factors that have a predictive value (predictors) for the response to different drugs in RA treatment, especially recent advances. These predictors include but are certainly not limited to genetic variations, clinical factors, and demographic factors. However, no clinical application is currently available. This review also describes the challenges in treating patients with RA and the need for personalized medicine. At the end of this review, we discuss possible strategies to enhance the prediction of drug responsiveness in patients with RA.

The Usefulness of Cardiac Biomarker in Patients with Acute Ischemic Stroke

BACKGROUND: Cardiac enzymes such as creatine kinase-MB, troponin I, and brain natriuretic peptide (BNP) are thought to be useful prognostic factors in patients with acute ischemic stroke. This study investigated the efficacy of cardiac biomarkers as prognostic factors. METHODS: We reviewed patients with acute ischemic stroke whose cardiac biomarkers had been measured and who were admitted to our hospital between January 2012 and December 2013. The cardiac biomarkers were measured within 24 hours after admission to the emergency room. We evaluated the clinical characteristics and compared the outcomes of the patients based on their cardiac biomarkers. RESULTS: The following cardiac biomarkers were measured in 219 patients with acute ischemic stroke: creatine kinase-MB (n=218), troponin I (n=219), and BNP (n=143). Statistically significant differences were observed in older age (68.77+/-12.42 vs. 74.59+/-6.68, p<0.05), insula involvement (30.5% vs. 59.1%, p<0.01), and higher BNP (259.75+/-422.65 vs. 667.06+/-1093.22, p<0.01). CONCLUSIONS: These results suggest that measuring all cardiac biomarkers may be not effective in determining the prognosis of acute ischemic stroke. However, BNP may be a superior to troponin I in predicting the prognosis.

Objective To determine whether Nutritional Risk Screening 2002 (NRS2002) of admission independently predicts outcome of non-invasive positive pressure ventilation (NIPPV) in chronic obstructive pulmonary disease (COPD) patients during hypercapnic respiratory failure.Methods Patients with COPD presenting with hypercapnic respiratory failure at Sichuan University Hospital between December 2010 and May 2012 and receiving NIPPV were studied prospectively.NRS2002 was measured before NIV administration.233 patients met the inclusion criteria,with NIPPV failed in 71 cases and succeed in 162 cases.The patients were followed up till they were discharged.Results After multivariate Logistic regression,the items such as baseline PaCO2,NRS2002 score could predicted 76.4％ of the failure outcome.The area under the curve was 0.767.The positive predictive value was 35.23％.The negative predictive value was 84.21％.Conclusions We can predict the risk failure of NIPPV in patients with COPD and hypercapnic respiratory failure with NRS2002 score and baseline PaCO2,and adjust the treatment project according to the evaluation result.NRS2002 supply non-invasive and portable method for predicting the failure of NIPPV.

Estado nutricional, clínico e padrão alimentar de pessoas vivendo com HIV/Aids em assistência ambulatorial no município de São Paulo / Nutritional and clinical status, and dietary patterns of people living with HIV/AIDS in ambulatory care in Sao Paulo, Brazil

INTRODUÇÃO: Atualmente, a abordagem nutricional desempenha papel essencial no tratamento de pessoas que vivem com HIV/aids, particularmente no caso de alterações metabólicas pelo uso da terapia antirretroviral (TARV) que podem estar associadas ao maior risco de doenças cardiovasculares (DCV). OBJETIVO: Caracterizar o estado nutricional, clínico e a qualidade da dieta de pessoas que vivem com HIV/aids. METODOLOGIA: Trata-se de um estudo transversal envolvendo pessoas que vivem com HIV/aids em atendimento na rede de serviços especializados no município de São Paulo. Os usuários desta rede, em uso ou não de TARV, foram recrutados no período de dezembro de 2004 a maio de 2006, durante consultas de rotina. Foram coletados dados sociodemográficos, clínicos, bioquímicos, antropométricos e dietéticos. A qualidade da dieta foi avaliada segundo escores de padrão de consumo predominantemente "não protetor" e "protetor" para DCV. RESULTADOS: A amostra foi constituída por 238 pacientes em TARV e 76 sem TARV. A média dos níveis de colesterol total, triglicérides e glicemia foram maiores no grupo TARV (p < 0,001). A maior parte dos participantes do estudo, com e sem TARV, apresentava-se eutrófica, com média de índice de massa corporal 24,4 (± 4,3) e 24,3 (± 3,5) kg/m², respectivamente. A relação cintura-quadril foi maior entre homens em TARV que entre aqueles sem TARV (0,90 ± 0,06 versus 0,87 ± 0,05) (p < 0,001). O grupo em TARV apresentou média de escores indicativa de maior consumo de alimentos "não protetores" para DCV (p = 0,001). CONCLUSÃO: Foram evidenciadas condições nutricionais e metabólicas indesejáveis entre aqueles em TARV, predisponentes ao risco de DCV. É apontada a necessidade de direcionamento das intervenções em saúde a pessoas que vivem com HIV/aids, para o controle dos fatores associados a essas doenças antes do desfecho final.

INTRODUCTION: Nutrition currently plays a key role in the treatment of people living with HIV/AIDS (PLHA), especially in the case of metabolic alterations due to highly active antiretroviral therapy (HAART), which could be related to cardiovascular diseases (CD). OBJECTIVE: to describe the nutritional and clinical status, and the quality of diet of PLHA. METHODS: It is a cross-sectional study involving a network of ambulatory care facilities for PLHA in the city of São Paulo, Brazil. Patients, in use of HAART or not, were selected from December 2004 to may 2006, through routine clinic visits. We collected: socio-demographic, clinical, biochemical, anthropometric measures and dietary data. Diet quality was evaluated according to a "protecting" or "non-protecting" pattern of consumption scores for CD. RESULTS: The sample had 238 patients on HAART and 76 without treatment. Mean serum levels of total cholesterol, triglycerides and glucose were higher in the HAART group (p < 0.001). The majority of patients of both the treated and untreated group were eutrophic with a mean body mass index (BMI) of 24.4 (± 4.3) kg/m² and 24.3 (± 3.5), respectively. The waist-hip ratio was higher among men on HAART (0.90 ± 0.06 versus 0.87±0.05) (p < 0.001). The HAART group showed a mean food pattern score indicating a higher consumption of "non-protecting" foods for CD (p = 0.001). CONCLUSION: The results showed undesired nutritional and metabolic conditions among patients on HAART associated with CD. It is necessary to manage health intervention programs for PLHA in order to control cardiovascular risk factors before final outcomes.
