Application of positive airway pressure in restoring pulmonary function and thoracic mobility in the postoperative period of bariatric surgery: a randomized clinical trial / Aplicação de pressão positiva nas vias aéreas na restauração da função pulmonar e da mobilidade torácica no pós-operatório de cirurgia bariátrica: um ensaio clínico randomizado

Objective: To evaluate whether the application of bilevel positive airway pressure in the postoperative period of bariatric surgery might be more effective in restoring lung volume and capacity and thoracic mobility than the separate application of expiratory and inspiratory positive pressure. Method: Sixty morbidly obese adult subjects who were hospitalized for bariatric surgery and met the predefined inclusion criteria were evaluated. The pulmonary function and thoracic mobility were preoperatively assessed by spirometry and cirtometry and reevaluated on the 1st postoperative day. After preoperative evaluation, the subjects were randomized and allocated into groups: EPAP Group (n=20), IPPB Group (n=20) and BIPAP Group (n=20), then received the corresponding intervention: positive expiratory pressure (EPAP), inspiratory positive pressure breathing (IPPB) or bilevel inspiratory positive airway pressure (BIPAP), in 6 sets of 15 breaths or 30 minutes twice a day in the immediate postoperative period and on the 1st postoperative day, in addition to conventional physical therapy. Results: There was a significant postoperative reduction in spirometric variables (p<0.05), regardless of the technique used, with no significant difference among the techniques (p>0.05). Thoracic mobility was preserved only in group BIPAP (p>0.05), but no significant difference was found in the comparison among groups (p>0.05). Conclusion: The application of positive pressure does not seem to be effective in restoring lung function after bariatric surgery, but the use of bilevel positive pressure can preserve thoracic mobility, although this technique was not superior to the other techniques. .

Objetivo: Avaliar se a aplicação de dois níveis de pressão positiva nas vias aéreas no pós-operatório de cirurgia bariátrica pode ser mais efetiva do que quando aplicadas pressões positivas expiratória e inspiratória separadamente na restauração dos volumes e capacidades pulmonares e na mobilidade torácica. Método: Foram avaliadas 60 voluntárias adultas, obesas mórbidas, internadas para realização da cirurgia bariátrica. Afunção pulmonar e a mobilidade torácica foram avaliadas por meio da espirometria e da cirtometria no pré-operatório e reavaliadas no primeiro pós-operatório. Após a avaliação pré-operatória, as voluntárias foram randomizadas e alocadas nos grupos G EPAP (n=20), G RPPI (n=20) e G BIPAP (n=20) e então receberam a intervenção proposta, pressão positiva expiratória nas vias aéreas (EPAP), respiração por pressão positiva inspiratória (RPPI) ou pressão positiva binível nas vias aéreas (BIPAP), em sessões de seis séries de 15 respirações ou de 30 minutos, duas vezes ao dia no pós-operatório imediato e no primeiro pós-operatório, além do tratamento fisioterapêutico convencional. Resultados: Houve redução significativa das variáveis espirométricas no pós-operatório (p<0,05), independente do recurso utilizado, não havendo diferença significativa entre as técnicas (p>0,05), e preservação da mobilidade torácica somente nas voluntárias do grupo BIPAP (p>0,05), porém sem diferença nas comparações entre os grupos (p>0,05). Conclusão: A aplicação de pressão positiva parece não ser efetiva na restauração da função ...

Functional priorities reported by parents of children with cerebral palsy: contribution to the pediatric rehabilitation process / Prioridades funcionais identificadas por pais de crianças com paralisia cerebral:contribuições para o processo de reabilitação infantil

Background: Collaborative actions between family and therapist are essential to the rehabilitation process, and they can be a catalyst mechanism to the positive outcomes in children with cerebral palsy (CP). Objectives: To describe functional priorities established by caregivers of CP children by level of severity and age, and to assess changes on performance and satisfaction on functional priorities reported by caregivers, in 6-month interval. Method: 75 CP children, weekly assisted at Associação Mineira de Reabilitação, on physical and occupational therapy services. The following information was collected: gross motor function (Gross Motor Function Classification System-GMFCS) and functional priorities established by caregivers (Canadian Occupational Performance Measure-COPM). Data were collected in two moments, with a 6-month interval. Results: The main functional demands presented by caregivers were related to self-care activities (48.2%). Parents of children with severe motor impairment (GMFCS V) pointed higher number of demands related to play (p=0.0036), compared to the other severity levels. Parents of younger children reported higher number of demands in mobility (p=0.025) and play (p=0.007), compared to other age groups. After 6 months, there were significant increase on COPM performance (p=0.0001) and satisfaction scores (p=0.0001). Conclusions: Parents of CP children identified functional priorities in similar performance domains, by level of severity and age. Orienting the pediatric rehabilitation process to promote changes in functional priorities indentified by caregivers can contribute to the reinforcement of the parent-therapist collaboration. .

Contextualização: Ações colaborativas entre família e terapeuta são essenciais para o processo de reabilitação, podendo constituir mecanismo catalisador de desfechos funcionais positivos para crianças com paralisia cerebral (PC). Objetivos: Descrever prioridades funcionais identificadas por cuidadores de crianças com PC por nível de gravidade e idade e avaliar mudanças no desempenho e satisfação reportadas pelos cuidadores nas prioridades identificadas no intervalo de seis meses. Método: De 75 crianças com PC, atendidas semanalmente naAssociação Mineira de Reabilitação, nos serviços de fisioterapia e de terapia ocupacional, foram coletadas informações referentes à função motora grossa (Sistema de Classificação da Função Motora Grossa-GMFCS) e às prioridades funcionais estabelecidas pelos cuidadores (Medida Canadense de Desempenho Ocupacional-COPM). Os dados foram coletados em dois períodos, com intervalo de seis meses. Resultados: As principais demandas apontadas pelos cuidadores referiram-se às atividades de cuidados pessoais (48,2%). Pais de crianças com comprometimento motor grave (GMFCS V) apresentaram maior número de demandas relacionadas ao brincar (p=0,036), comparadas com outros níveis de comprometimento. Pais de crianças mais jovens reportaram maior número de demandas em mobilidade (p=0,025) e brincar (p=0,007) em relação aos outros grupos etários. Após seis meses, observou-se aumento significativo dos escores de desempenho (p=0,0001) e de satisfação (p=0,0001) da COPM. Conclusões: Pais de crianças com PC identificaram prioridades funcionais em áreas de desempenho semelhantes por nível de gravidade da função motora grossa e por grupo etário.

Breathing exercises: influence on breathing patterns and thoracoabdominal motion in healthy subjects / Exercícios respiratórios: influência sobre o padrão respiratório e o movimento toracoabdominal em indivíduos saudáveis

BACKGROUND: The mechanisms underlying breathing exercises have not been fully elucidated. OBJECTIVES: To evaluate the impact of four on breathing exercises (diaphragmatic breathing, inspiratory sighs, sustained maximal inspiration and intercostal exercise) the on breathing pattern and thoracoabdominal motion in healthy subjects. METHOD: Fifteen subjects of both sexes, aged 23±1.5 years old and with normal pulmonary function tests, participated in the study. The subjects were evaluated using the optoelectronic plethysmography system in a supine position with a trunk inclination of 45° during quiet breathing and the breathing exercises. The order of the breathing exercises was randomized. Statistical analysis was performed by the Friedman test and an ANOVA for repeated measures with one factor (breathing exercises), followed by preplanned contrasts and Bonferroni correction. A p<0.005 value was considered significant. RESULTS: All breathing exercises significantly increased the tidal volume of the chest wall (Vcw) and reduced the respiratory rate (RR) in comparison to quiet breathing. The diaphragmatic breathing exercise was responsible for the lowest Vcw, the lowest contribution of the rib cage, and the highest contribution of the abdomen. The sustained maximal inspiration exercise promoted greater reduction in RR compared to the diaphragmatic and intercostal exercises. Inspiratory sighs and intercostal exercises were responsible for the highest values of minute ventilation. Thoracoabdominal asynchrony variables increased significantly during diaphragmatic breathing. CONCLUSIONS: The results showed that the breathing exercises investigated in this study produced modifications in the breathing pattern (e.g., increase in tidal volume and decrease in RR) as well as in thoracoabdominal motion (e.g., increase in abdominal contribution during diaphragmatic breathing), among others. .

CONTEXTUALIZAÇÃO: Os mecanismos envolvidos na execução dos exercícios respiratórios não foram completamente elucidados. OBJETIVOS: Avaliar o impacto de quatro exercícios respiratórios(diafragmático, suspiros inspiratórios, inspiração máxima sustentada e intercostal) sobre o padrão respiratório e o movimento toracoabdominal em indivíduos saudáveis. MÉTODO: Participaram do estudo15 indivíduos de ambos os sexos (23±1,5 anos com prova de função pulmonar normal). Os indivíduos foram avaliados por meio da pletismografia optoeletrônica na posição supina com inclinação de tronco de 45° durante a respiração tranquila e durante a realização dos exercícios respiratórios. A ordem dos exercícios foi randomizada. Os dados foram analisados pelo teste de Friedman e ANOVA para medidas repetidas com um fator (exercícios respiratórios) seguidos de contrastes pré-planejados e correção de Bonferroni, sendo p<0,005 considerado significativo. RESULTADOS: Todos os exercícios respiratórios promoveram aumento significativo do volume corrente da parede torácica (VCpt) e redução da frequência respiratória (f) quando comparados à respiração tranquila. O exercício diafragmático foi responsável pelo menor VCpt, menor contribuição da caixa torácica e maior contribuição do abdômen. A inspiração máxima sustentada promoveu redução significativamente maior da f comparada aos exercícios diafragmático e intercostal. Os exercícios suspiros inspiratórios e intercostal foram responsáveis pelos maiores valores de ventilação minuto. Os índices de assincronia toracoabdominal aumentaram significativamente ...

EC-18, a Synthetic Monoacetyldiacylglyceride, Inhibits Hematogenous Metastasis of KIGB-5 Biliary Cancer Cell in Hamster Model

EC-18 (monoacetyldiacylglyceride) stimulates T cell production of IL-2, IL-4, IL-12, IFN-gamma, and GM-CSF in vitro. To study the effects of these cytokines stimulated by EC-18 on cancer cells, we applied hamster biliary cancer model, a difficult cancer to treat. Cancer (KIGB-5) cells were given intravenously to produce hematogenous metastatic lung lesions which were treated with EC-18 at 10, 25, and 50 mg/kg/day respectively. The fourth group was untreated control. At 4th, 8th, and 12th week the lungs were examined. EC-18 treated groups showed only a few microscopic lung lesions and no evidence of metastatic lesion with highest dose whereas widespread gross lung lesions were observed in untreated control. To investigate whether the anti-tumor effect of EC-18 is associated with suppression of tumor cell Toll-like receptor 4 (TLR-4) expression in addition to stimulation of the immune cells, KIGB-5 cells were exposed to LPS with or without EC-18. TLR-4 mRNA and protein expression, measured by reverse transcriptase PCR (RT-PCR), real-time quantitative PCR and western blot analysis, showed suppression of TLR-4 expression in KIGB-5 cells treated with EC-18 compared with control. In conclusion, EC-18 has a significant anti-tumor effect in this experimental model of biliary cancer suggesting potential for clinical application to this difficult cancer.

Evaluation of garlic oil as a contact dissolution agent for gallstones: comparison with monooctanoin.

AIM: To find a better contact solvent to dissolve gallstones we studied invitro use of garlic oil and compared it with monooctanoin. METHODS: In the first stage gall stones obtained from patients after cholecystectomy were subjected to dissolution in different concentrations of garlic oil. Then the rate of dissolution of gall stones in garlic oil was compared to that in monooctanoin in stage II. Efficacy of various concentration of garlic oil and monoocatanoin in dissolving gallstones in artificial gall bladder and common bile duct models were compared in stage III. RESULTS: Garlic oil dissolved the cholesterol gall stones in proportion to the concentration used. The gall stone fragmentation was faster [6 hours V/s 36 hours] and more [88.30% V/s 71.01%] by garlic oil in comparison to monooctanoin in test tubes and even in artificial gallbladder and common bile duct models. CONCLUSIONS: Garlic oil is a better contact dissolving agent of gallstones than monooctanoin.
