Myocardium Contructility Characterization from Echocardiograms using Optical Flow
Manuel Calheiros Lobo; A. Sousa PereiraIn this thesis we propose a method to determine the local contraction patterns of the myocardium by computing the optical flow in a sequence of echocardiograms. The displacement field describing the 2-D motion of a region-of-interest (ROI) is computed between a pair of images by solving the optical flow equations under the assumption that the 2-0 strain tensors constant within the ROI and between the pair of su...
Febre de etiologia indeterminada - encruzilhada de diagnósticos
Oliveira, M.; Meireles, C.; Costa, P.; Guedes, M.; Lobo, A.L.Introdução: Os principais diagnósticos a considerar numa febre de etiologia indeterminada incluem as causas infecciosas, reumatológicas, imunológicas e neoplásicas. Caso clínico: Apresentamos o caso de uma criança de quatro anos do sexo masculino, observada por febre, cervicalgia e claudicação da marcha. Detectou-se anemia e marcadores inflamatórios elevados. No internamento foi-se evidenciando palidez, exantem...
Pneumonia Necrotizante A Propósito de Um Caso Clínico
Prazeres, T.; Dias, A.; Moura, R.; Fernandes, A.; Aguiar, I.; Lobo, A.ABSTRACT Introduction. Necrotizing Pneumonia (NP) is a serious complication of Community Acquired Pneumonia, whose incidence has been increasing in recent years. The authors present a case report of a child with NP and make a comprehensive review of the subject. Case report. A 22 months old girl, without history of relevant diseases, presented in Hospital because of high fever lasting six days. She appeared ill...
Anti-tumor necrosis factor-a for the treatment of steroid-refractory acute graf...
Nogueira,M.C.; Azevedo,A.M.; Pereira,S.C.M.; Ferreira,J.L.; Lerner,D.; Lobo,A.M.G.; Tavares,R.C.B.S.; Tabak,D.G.; Lorenzi,N.; Renault,I.Z.Allogeneic stem cell transplantation has been increasingly performed for a variety of hematologic diseases. Clinically significant acute graft-versus-host disease (GVHD) occurs in 9 to 50% of patients who receive allogeneic grafts, resulting in high morbidity and mortality. There is no standard therapy for patients with acute GVHD who do not respond to steroids. Studies have shown a possible benefit of anti-TNF...
A brief diagnostic screening instrument for mental disturbances in general medi...
Fink, P; Ørnbøl, E; Huyse, F; Jonge, P; Lobo, A; Herzog, T; Slaets, J; Arolt, V; Cardoso, G; Rigatelli, M; Hansen, MOBJECTIVE: Mental illness is prevalent among general hospital ward patients but often goes unrecognised. The aim of this study was to validate the SCL-8d as a brief questionnaire for mental disturbances for use in general hospitals. METHODS: The study included 2040 patients, 18 years or older, consecutively admitted to 11 general internal medicine wards in seven European countries. All patients were screened on...
Feeding pattern of Salminus maxillosus (Pisces, Characidae) at Cachoeira das Em...
ESTEVES,K. E.; PINTO LÔBO,A. V.Diet of 364 specimens of the dourado (Salminus maxillosus) was studied monthly at Cachoeira das Emas from November/1996 to May/1998, considered the breeding ground of this and other migrant fishes of Mogi-Guaçu River. Only adults were found at this site, and diet consisted exclusively of fish, with predominance of Leporinus sp. Seasonal variation in feeding activity was highest during some months of the rainy a...
Consultation-Liaison psychiatric service delivery: results from a European study
Huyse, F; Herzog, T; Lobo, A; Malt, U; Opmeer, B; Stein, B; Jonge, P; Dijck, R; Creed, F; Crespo, MD; Cardoso, GThe reported findings of the European Consultation-Liaison Workgroup (ECLW) Collaborative Study describe consultation-liaison service delivery by 56 services from 11 European countries aggregated on a C-L service level. During the period of 1 year (1991), the participants applied a standardized, reliability tested method of patient data collection, and data were collected describing pertinent characteristics of...
Mental disturbances and perceived complexity of nursing care in medical inpatie...
Jonge, P; Zomerdijk, M; Huyse, F; Fink, P; Herzog, T; Lobo, A; Slaetz, J; Harolt, V; Balogh, N; Cardoso, G; Rigatelli, MAIMS AND OBJECTIVES: The relationship between mental disturbances - anxiety and depression, somatization and alcohol abuse - on admission to internal medicine units and perceived complexity of care as indicated by the nurse at discharge was studied. The goal was to study the utility of short screeners for mental disturbances to select patients for case-management on admission. DESIGN: The study had a cohort des...
COMPRI--an instrument to detect patients with complex care needs: results from ...
Huyse, F; Jongue, P; Slaets, J; Lobo, A; Herzog, T; Lyons, J; Opmeer, B; Stein, B; Arolt, V; Cardoso, GThe authors developed a screening instrument to detect patients in need of complex care coordination at admission to a general hospital. On the basis of a series of risk factors for care complexity, the authors constructed a short, care complexity prediction instrument (COMPRI) and assessed its qualities. The COMPRI is an easily administered screening instrument that detects patients at risk for complex care ne...
Risk factors for complex care needs in general medical inpatients: results from...
de Jonge, P; Huyse, F; Herzog, T; Lobo, A; Slaets, J; Lyons, J; Opmeer, B; Stein, B; Arolt, V; Balogh, N; Cardoso, GThe authors linked admission risk factors to a series of indicators for complex care delivery to enable detection of patients in need of care coordination at the moment of admission to the general hospital. The authors found 13 risk factors to be predictive of more than one indicator of care complexity. An admission risk screening procedure to detect patients in need of care coordination should focus on these r...
