Predictors of attrition and immunological failure in HIV- 1 patients on highly ...
Palladino, Claudia; Briz, Verónica; Bellón, José María; Bártolo, Inês; Carvalho, Patrícia; Camacho, Ricardo; Munõz-Fernandes, M. Ángeles; Bastos, Rui"In Mozambique, the evaluation of retention in HIV care and ART programmes is limited. To assess rate and predictors of attrition (no retention in care) and HAART effectiveness in HIV-1 infected patients who pay for medication and laboratory testing in Mozambique, we conducted a multicenter survey of HIV-1-infected patients who started HAART during 2002– 2006. Cox proportional hazard models were used to assess ...
Cell-associated viral burden provides evidence of ongoing viral replication in ...
Soares, Rui S.; Tendeiro, Rita; Foxall, Russell B.; Baptista, António P.; Cavaleiro, Rita; Gomes, Perpétua; Camacho, Ricardo; Valadas, EmíliaCopyright © 2011, American Society for Microbiology. All Rights Reserved. ; Viremia is significantly lower in HIV-2 than in HIV-1 infection, irrespective of disease stage. Nevertheless, the comparable proviral DNA burdens observed for these two infections indicate similar numbers of infected cells. Here we investigated this apparent paradox by assessing cell-associated viral replication. We found that untreate...
Origin and Epidemiological History of HIV-1 CRF14_BG
Bártolo, Inês; Abecasis, Ana B.; Borrego, Pedro; Barroso, Helena; McCutchan, Francine; Gomes, Perpétua; Camacho, Ricardo; Taveira, NunoBackground: CRF14_BG isolates, originally found in Spain, are characterized by CXCR4 tropism and rapid disease progression. This study aimed to identify the origin of CRF14_BG and reconstruct its epidemiological history based on new isolates from Portugal. ; Methodology/Principal Findings: C2V3C3 env gene sequences were obtained from 62 samples collected in 1993–1998 from Portuguese HIV-1 patients. Full-length...
Compile the hypothesis space: do it once, use it often
Nuno A. Fonseca; Rui Camacho; Ricardo Rocha; Vítor Santos CostaInductive Logic Programming (ILP) is a powerful and well-developed abstraction for multi-relational data mining techniques. Despite the considerable success of ILP, deployed ILP systems still have efficiency problems when applied to complex problems. In this paper we propose a novel technique that avoids the procedure of deducing each example to evaluate each constructed clause. The technique is based on the Mo...
Cirurgia conservadora de próteses aórtica e mitral na endocardite infecciosa
KASSAB,Kanim Kalil; MENEGOLI,José Antônio Garcia; PICARDI,Vera Lúcia A. M.; ALMEIDA,Marcos Cesar V. de; SABINO,Emil; SAN JUAN,EdgardA endocardite infecciosa (EI) acometendo próteses valvares é uma complicação freqüente, sendo tratada geralmente com cirurgia, devido ao seu difícil controle clínico e má resposta à antibioticoterapia. Este relato descreve o caso de uma paciente com EI, acometendo simultaneamente as biopróteses aórtica (Ao) e mitral (Mi) após vinte e quatro meses de cirurgia de implantes valvares, submetida a tratamento cirúrgi...
Mixoma de átrio esquerdo associado a derrame pleural
MEIRA,Enoch Brandão de Souza; CAMACHO,Ricardo Gomes; MEIRA,Daniela Barros de Souza; PÓVOA,Rui; KASSAB,Kanim Kalil; ANIJAR,Alberto MauroHomem de 65 anos apresentando emagrecimento, dispnéia e derrame pleural (DP) recorrente. A avaliação cardiológica evidenciou ruflar diastólico (3/6) no foco mitral e hiperfonese da 1ª bulha. O ecocardiograma e o estudo hemodinâmico mostraram uma grande massa tumoral no átrio esquerdo (AE), sugerindo mixoma e hipertensão pulmonar. A biópsia pleural revelou pleurite crônica inespecífica. O paciente foi submetido ...
