Life-Space Mobility of Subjects With COPD on Long-Term Oxygen Therapy Delivered by Non-Portable Devices.

BACKGROUND: Mobility is human body movement in all its forms, including bed-to-chair transfer, walking, daily tasks, participating in work and social functions, exercising, and using public transport. The mobility of people living with COPD is affected negatively by the disease symptoms. However, limited data are available on the life-space mobility in people with COPD on long-term oxygen therapy (LTOT). This study aimed to explore the life-space mobility in subjects with COPD on LTOT and verify whether life-space mobility is associated with comorbidities and symptoms, activity in daily life, exercise capacity performance, and quality of life. METHODS: This cross-sectional study enrolled 61 subjects with COPD on LTOT (73.0 ± 8.8 y, FEV1 41.7 ± 16.0% predicted, on LTOT for 2.8 ± 3.3 y). Life-space mobility (Life-Space Assessment), LTOT usage time, comorbidities (Charlson comorbidity index), need for support from a caregiver, exercise capacity (6-min step test), dyspnea (modified Medical Research Council scale), activities of daily living (ADLs, Katz scale), and health-related quality of life (EuroQol 5-Dimension Questionnaire) were assessed. RESULTS: Mobility restriction was identified in 90% of participants. Life-space mobility was negatively associated with the number of comorbidities (rs = -0.31, P = .02), dyspnea symptom (rs = -0.60, P < .001), and positively associated with basic ADLs performance (rs = 0.59, P < .001) and exercise capacity (rs = 0.49, P < .001). Dyspnea and exercise capacity were independent predictors of vital space mobility. CONCLUSIONS: Subjects with COPD on LTOT had limited life-space mobility. Interventions to reduce dyspnea and improve exercise capacity should be prioritized to increase this population's domestic and community mobility.

Caregiver Burden Is Associated With the Physical Function of Individuals on Long-Term Oxygen Therapy.

BACKGROUND: The influence of physical function of individuals on long-term oxygen therapy (LTOT) on caregiver burden is underexplored. This study investigated the association of caregiver burden with physical function of individuals on LTOT and the association between caregiver's burden and quality of life. METHODS: This was a cross-sectional study. Informal caregivers were assessed for burden using the Caregiver Burden Inventory (CBI), the European Quality of Life 5 Dimension questionnaire index (EQ-5D index) and its Visual Analog Scale (EQ-VAS). Physical function of subjects on LTOT was assessed by dyspnea, activities of daily living (ADLs), and mobility. Univariate and multivariate linear regression models were explored. RESULTS: Fifty-four caregivers (54.7 ± 16.1 y, 74.1% female) were included. CBI total score was correlated with subject's dyspnea (r = 0.369, P = .006) and ADLs (r = 0.300, P = .03). In the multivariate regression models, subject's physical function limitation due to dyspnea explained 26.4% of the CBI total score variance (P = .005). In the CBI dimension analysis, the time-dependence caregiver burden was correlated with subject's dyspnea (r = 0.335, P = .01), ADLs (r = 0.436, P = .001), and mobility (r = -0.415, P = .002). CBI developmental and physical caregiver burden were correlated with dyspnea (r = 0.309, P = .02; r = 0.363, P = .007) and ADLs (r = 0.274, P = .045; r = 0.299, P = .03). Emotional caregiver burden was correlated with dyspnea (r = 0.333, P = .01). Higher CBI total score was correlated with worse quality of life on EQ-5D index (rs= -0.374, P = .005) and EQ-VAS (rs= -0.494, P = .001) in caregivers. CONCLUSIONS: Increased caregiver burden was associated with higher physical limitation due to dyspnea and dependence in ADLs of individuals on LTOT. The increased burden was associated with a worse caregiver's quality of life.

Infliximab-induced remission improves physical activity in patients with active Crohn's disease.

AIM: To compare the level of physical activity (PA), exercise capacity, and body composition before and after infliximab-induced clinical remission in patients with Crohn's disease (CD). METHODS: This prospective longitudinal study evaluated 44 adult outpatients with active CD before infliximab administration and 24 weeks after infliximab therapy. The patients were evaluated for PA in daily life, exercise capacity, muscle strength, and body composition. RESULTS: 38 (86.4%) patients achieved infliximab-induced remission at 24 weeks and presented an increment in the number of steps taken of 1092 (7440±2980 vs. 6348±3177, respectively; p=0.006). The inactive time was reduced when compared to the baseline value (454.2±106.3 vs. 427.9±97.8, respectively; p=0.033). There was no difference in the distance walked before and after infliximab therapy, while there was an increase in the fat mass index in responders to infliximab compared to the baseline (19.1±7.6 vs. 14.9±5.8; p=0.001). CONCLUSIONS: Infliximab-induced remission was shown to be effective for increasing physical activity by improving the number of steps and reducing inactive time. The maintenance of clinical remission associated with incentives to regular PA may contribute to making these patients reach an ideal level of PA.

RESUMO OBJETIVO: Comparar o nível de atividade física (AF), capacidade de exercício e composição corporal antes e após remissão clínica induzida por infliximabe em pacientes com doença de Crohn (DC). MÉTODOS: Neste estudo longitudinal prospectivo, foram envolvidos 44 pacientes ambulatoriais adultos com DC ativa avaliados antes e depois de 24 semanas de terapia com infliximabe. Os pacientes foram avaliados quanto à AF, capacidade de exercício, força muscular e composição corporal. RESULTADOS: 38(86,4%) pacientes alcançaram remissão induzida por infliximabe em 24 semanas e apresentaram aumento no número de passos de 1092 (7440±2980 vs. 6348±3177, respectivamente; p=0,006). O tempo de inatividade foi reduzido quando comparado ao basal (454,2±106,3 vs. 427,9±97,8, respectivamente; p=0,033). Não houve diferença na distância percorrida antes e após a terapia com infliximabe, enquanto houve aumento no índice de massa gorda nos respondedores ao infliximabe em comparação ao basal (19,1±7,6 vs. 14,9±5,8; p=0,001). CONCLUSÕES: A remissão induzida pelo infliximabe mostrou-se eficaz no aumento da atividade física, melhorando o número de passos e reduzindo o tempo inativo. A manutenção da remissão clínica associada a incentivos à AF regular pode contribuir para que esses pacientes atinjam um nível ideal de AF.

PHYSICAL ACTIVITY IN DAILY LIFE, EXERCISE CAPACITY AND QUALITY OF LIFE IN PATIENTS WITH CROHN'S DISEASE ON INFLIXIMAB-INDUCED REMISSION: A PRELIMINARY STUDY.

BACKGROUND: Physical activity in daily life and exercise capacity have not been assessed in patients with Crohn's disease to date. OBJECTIVE: To evaluate the physical activity in daily life, exercise capacity, quality of life, and prevalence of mood disorders in patients with moderate-to-severe Crohn's disease on infliximab-induced remission and the possible associations among variables. METHODS: A cross-sectional preliminary study was conducted. Twenty-six patients with Crohn's disease and 20 controls were selected. Participants underwent evaluation of physical activity in daily life (triaxial accelerometer), exercise capacity (shuttle walk test), handgrip strength, quality of life, and presence of mood disorders. RESULTS: The number of steps taken (7446±3081 vs 7898±2487), active time (80.6±42 vs 89.7±24.3min), shuttle walk test distance [665 (405) vs 710 (409) m] and handgrip strength [31 (15) vs 29 (20) kgf did not show any difference between the patients with Crohn's disease and the controls. The time spent lying down [95.8 (68.8) vs 60.9 (74.7) min] was greater and some domains of the quality of life were superior in the patients with Crohn's disease. No correlation was observed between the physical activity in daily life and quality of life or presence of mood disorders in patients with Crohn's disease. CONCLUSION: Patients with Crohn's disease on infliximab-induced remission, despite to more time spent lying down, they have the same level of physical activity in daily life and exercise capacity min compared with the controls.

RESUMO CONTEXTO: A atividade física na vida diária e a capacidade de exercício não tem sido avaliada em pacientes com doença de Crohn. OBJETIVO: Avaliar a atividade física na vida diária, capacidade de exercício, qualidade de vida e distúrbios de humor em pacientes com doença de Crohn moderada-grave em remissão induzida pelo infliximabe, e as possíveis associações entre essas variáveis. MÉTODOS: Este foi um estudo preliminar transversal, envolvendo 26 pacientes com doença de Crohn e 20 controles. Os participantes realizaram as seguintes avaliações: atividade física na vida diária por meio de um acelerômetro triaxial, capacidade de exercício (teste de Shuttle), força de preensão palmar, qualidade de vida e distúrbios do humor. RESULTADOS: O número de passos registrados (7446±3081 vs 7898±2487), o tempo ativo (80,6±42,0 vs 89,7±24,3min), a distância caminhada no teste de Shuttle 665 (405) vs 710 (409) m, e a força de preensão manual 31(15) vs 29 (20) kgf não mostraram diferenças entre os pacientes com doença de Crohn e os controles, respectivamente. O tempo gasto na posição deitada 95.8 (68.8) vs 60.9 (74.7) min, e alguns domínios da qualidade de vida foram maiores nos pacientes com doença de Crohn. Nenhuma correlação foi observada entre a atividade física na vida diária e a qualidade de vida ou distúrbios do humor nos pacientes com doença de Crohn. CONCLUSÃO: Pacientes com doença de Crohn em remissão induzida por infliximabe, apesar de passarem mais tempo deitados, apresentam mesmo nível de atividade física e capacidade de exercício quando comparados aos controles.

Linhagens operantes e linhagens culturo-comportamentais: uma demonstração experimental / Operant lineages and culturo-behavior lineages: an experimental demonstration

Este estudo investigou a possibilidade de demonstração em laboratório de linhagens operantes e linhagens culturo-comportamentais. Linhagem operante descreve que em uma dada classe de respostas algumas topografias de respostas tornam-se mais frequentes que as demais membros dessa classe. Já linhagens culturo-comportamentais são (1) comportamentos aprendidos socialmente que (2) continuam a ser replicados no repertório de novos organismos e, cujas (3) consequências produzidas são suficientes para manter sua recorrência além de (4) manter a relação de controle por parte dos eventos ambientais antecedentes similares aqueles que evocaram o operante original. Participaram do estudo seis universitários. A tarefa experimental envolveu a inserção de algarismos em uma tarefa matemática. Os participantes desempenharam a tarefa em dupla com permissão de interações verbais.Foram mensurados os algarismos inseridos pelos participantes como propriedades definidoras da topografia das respostas. Os resultados encontrados indicaram que, em geral, uma topografia de resposta tornou-se mais frequente dentro de um universo de cinco topografias possíveis para reforçamento. Também observou-se replicação dessas topografias por aprendizagem social. Conclui-se que foi possível observar em laboratório a ocorrência de linhagens operantes e linhagens culturo-comportamentais. (AU)

This study has investigated the possibility of laboratory demonstration of operative and cultural lineages. The operant lineage describes that in a certain class of responses some topographies of responses become more frequent than the other members of this class. The culturo-behavior lineages are (1) socially learned behaviors that (2) continue to be replicated in the repertoire of new organisms and whose (3) consequences produced are sufficient to maintain their recurrence besides (4) maintaining the control relationship by previous environmental events similar to those that evoked the original operative. Six university students took part of the study. The experimental task involved the insertion of numbers in a math task. The participants performed the task in pairs with permission of verbal interactions. We measured the digits entered by the participants as defining properties of the topography of the responses. The results indicated that, in general, response topography became more frequent inside a universe of five possible topographies for reinforcement. A replication of such topographies was also observed for social learning. It was concluded that it was possible to observe, in laboratory, the occurrence of operant and culturo-behavior lineage.

Quantificação computadorizada dos índices de placa e cálculo dentais da imagem digital da superfície vestibular dos dentes de cães / Quantification computed indices card and calculation dealers of the digital picture of vestibular surface of teeth of dogs

A doença periodontal é causada pelo acúmulo de placa bacteriana sobre os dentes e estruturas adjacentes. Para sua mensuração têm sido formulados índices que consideram a quantidade e intensidade de placa bacteriana (PB) e de cálculo dental (CD) existentes na superfície dentária por meio de avaliação visual subjetiva. O presente estudo tem como objetivo avaliar o método de análise computadorizada para medição de área de PB e CD nos dentes de cães através da comparação com a avaliação visual. Foram utilizados 10 cães Beagles, três machos e sete fêmeas, com similares características e mantidos sob o mesmo manejo e dieta alimentar. As avaliações das superfícies vestibulares dos dentes ocorreram antes da profilaxia dentária, que foi realizada sob anestesia geral inalatória, e após sete dias para PB e após 28 dias para CD. A avaliação computadorizada da área de CD demonstrou ser estatisticamente melhor em relação à avaliação visual antes e após a profilaxia; entretanto, não demonstrou diferença significante na avaliação da PB. Concluiu-se que a avaliação computadorizada é vantajosa em relação à visual por conferir maior precisão na obtenção da proporção entre área total do dente e área acometida, mostrando-se estatistticamente superior na quantificação do CD após 28 dias.

Periodontal disease is caused by dental plaque accumulation on teeth and adjacent structures. Indices have been formulated for its measurement considering the amount and intensity of dental plaque (DP) and dental calculus (C) on the surface of teeth through subjective visual evaluation. This study aims at assessing the computerized analysis method for measurement of DP and C areas on the teeth of dogs by comparing it with the visual evaluation in the oral cavity. Ten beagle dogs with similar characteristics and kept under the same management and diet were used. Evaluations of oral cavity occurred before surgical prophylaxis (performed under general inhalation anesthesia) and after seven days for DP and 28 days for C. The computerized C area evaluation showed to be statistically better than the visual evaluation before and after prophylaxis. It was concluded that the computerized evaluation is beneficial when compared to visual evaluation, providing greater precision in the area measurement.

Dioctophyme renale (Goeze, 1782) in the abdominal cavity of a domestic cat from Brazil.

This study reports a case of parasitism by the giant kidney worm, Dioctophyme renale (Goeze, 1782), in the abdominal cavity of a domestic cat from Brazil. A female adult cat presenting prostration, dehydration, physical debility, pronounced jaundice and ascitis, was taken to the Department of Animal Parasitology of the Veterinary Institute of the Universidade Federal Rural do Rio de Janeiro, Brazil. Clinical signs suggested a case of peritonitis. The cat's clinical condition was grave and death occurred within a few days. During necropsy, a brownish-red nematode, 24.9cm long, was found in the abdominal cavity and was identified as a male adult D. renale. This study reports the first confirmed case of dioctophymatosis in the domestic cat. The parasite's aberrant location in the abdominal cavity suggests that the domestic cat is not a suitable host.

Hiper-infecção por Strongyloides Stercoralis: relato de caso / Strongyloides Stercoralis hyperinfection syndrome: case report

JUSTIFICATIVA E OBJETIVOS: O Strongyloides stercoralis é um agente comum de infecção do trato gastrintestinal. Em pacientes imunodeprimidos este nematódeo pode causar hiper-infecção, com manifestações pulmonares e sepse por germes gram-negativos. O objetivo deste relato foi apresentar um caso com evolução letal e ressaltar a importância do diagnóstico e do tratamento precoce. RELATO DO CASO: Paciente do sexo masculino, 60 anos, com diagnóstico de tumor de timo, submetido a tratamento cirúrgico, radioterapia e quimioterapia. Foi consultado na emergência relatando queixa de diarréia e dispnéia, sendo admitido na UTI após apresentar quadro de insuficiência respiratória aguda hipoxêmica e choque refratário, evoluindo para óbito. No aspirado traqueal, foi identificado larvas de Strongyloides stercoralis. CONCLUSÕES: A estrongiloidíase, apesar de tratar-se de infecção parasitária freqüentemente leve, em pacientes imunodeprimidos pode apresentar-se de forma grave e disseminada. Deve-se suspeitar deste agente em pacientes que vivem em áreas endêmicas, sendo o diagnóstico estabelecido através da pesquisa da larva do Strongyloides stercoralis na secreção traqueal e nas fezes.

BACKGROUND AND OBJECTIVES: Strongyloides Stercoralis is a common cause of gastrointestinal infection. This nematode can produce an overwhelming hyperinfection syndrome, especially in the immunocompromised patient. Typically, patients present with pulmonary symptoms, but subsequently they can acquire Gram-negative sepsis. The objective of this report is to describe a lethal case and call attention to the importance of early diagnosis and treatment. CASE REPORT: Male patient, 60 year-old with diagnosis of timoma, treated with surgery, radiotherapy and chemotherapy in the past. He presented to the emergency room complaining of diarrhea and dyspnea, and then transferred to the ICU after development of hypoxemic acute respiratory failure and refractory septic shock, and despite treatment the patient died. A bronchial sample of sputum showed Strongyloides stercoralis worms. CONCLUSIONS: Strongyloides stercoralis infection symptoms are usually mild, but in the setting of impaired host immunity, a disseminated and severe illness may occur. Clinicians must be aware for patients from endemic areas. Diagnosis may be established through sputum and stool examination for Strongyloides stercoralis worms.
