Propriedades MĂŠtricas da Escala Aachen Aphasia Test
No contexto atual do exercĂcio da profissĂŁo de enfermagem, com exigĂŞncia crescente a nĂvel de eficĂĄcia, eficiĂŞncia e prĂĄtica baseada na evidĂŞncia, torna-se imperativa a utilização de instrumentos de avaliação e medida, devidamente validados para as populaçþes que assistem e avaliam. O objetivo deste estudo foi conhecer as propriedades mĂŠtricas da escala Aachen Aphasia Test (AAT), aplicada a pessoas que sofreram um Acidente Vascular Cerebral (AVC). Foi realizada uma revisĂŁo sistemĂĄtica da literatura, atravĂŠs de bases de dados eletrĂłnicas, nos Ăşltimos 5 anos. Selecionaram-se 4 artigos que cumpriam os critĂŠrios, relacionados com a temĂĄtica. Pouca informação foi obtida relacionada com as propriedades mĂŠtricas da AAT. Apenas um dos artigos aborda informaçþes exatas e referentes Ă s propriedades mĂŠtricas da sua adaptação para a versĂŁo Portuguesa, que de acordo com os autores consultados sĂŁo robustas, comparĂĄveis Ă s da versĂŁo AlemĂŁ. Os restantes estudos recorrem a este instrumento como padrĂŁo na comparação com outros instrumentos
Fractional modeling dynamics of HIV and CD4+ T-cells during primary infection
In this paper, we introduce fractional-order into a model of HIV-1 infection of CD4+ T cells. We study the effect of the changing the average number of viral particles N with different sets of initial conditions on the dynamics of the presented model. Generalized Euler method (GEM) will be used to find a numerical solution of the HIV-1 infection fractional order model
Ears of the Armadillo: Global Health Research and Neglected Diseases in Texas
Neglected tropical diseases (NTDs) have\ud
been recently identified as significant public\ud
health problems in Texas and elsewhere in\ud
the American South. A one-day forum on the\ud
landscape of research and development and\ud
the hidden burden of NTDs in Texas\ud
explored the next steps to coordinate advocacy,\ud
public health, and research into a\ud
cogent health policy framework for the\ud
American NTDs. It also highlighted how\ud
U.S.-funded global health research can serve\ud
to combat these health disparities in the\ud
United States, in addition to benefiting\ud

Use of antibiotic spacers for knee endoprosthesis infections treatment
OBJCTIVE: The aim of this study is to evaluate the use of cement spacers impregnated with antibiotics for the treatment of infections in the nonconventional endoprostheses of the knee. METHODOLOGY: We have treated seven patients since 2004 (of which six were submitted to surgery in our service and one patient had been submitted to a primary tumor surgery in another removal service) with deep infection in knee tumor prosthesis. All patients were submitted to endoprosthesis removal and reconstructed with antibiotic cement spacer. All patients were monitored both clinically and by lab tests as for monitoring the evolution, being considered able for reviews after 6 (six) months without infections signs. RESULTS: We have noted a small predominance of infectious processes on the prosthesis inserted on proximal tibia as compared with distal femur (57.1% x 42.9%). The mean follow-up time of patients was 68.2 months. During the follow up, one patient died as a result of the root disease. Six patients out of seven were regarded as cured and one persisted with infection signs and symptoms. CONCLUSION: The results obtained up to date have motivated us to continue using this method of treatment.OBJETIVO: O objetivo do estudo ĂŠ avaliar a utilização dos espaçadores de cimento acrĂlico com antibiĂłtico no tratamento das infecçþes em endoprĂłteses nĂŁo convencionais de joelho. MĂTODO: Desde de 2004 foram tratados sete pacientes (seis pacientes operados no nosso serviço e um paciente que havia sido submetido a cirurgia primĂĄria do tumor em outro serviço) com infecção peri-endoprĂłtese nĂŁo convencional de joelho. Todos pacientes foram submetidos a retirada da endoprĂłtese e reconstrução com espaçador com cimento acrĂlico com antibiĂłtico. Todos os pacientes foram monitorados clĂnica e laboratorialmente quanto ao controle da evolução, sendo considerados aptos para a revisĂŁo e recolocação de endoprĂłtese apĂłs 06 (seis) meses sem sinais infecciosos RESULTADOS: Notamos um discreto predomĂnio do do processo infeccioso nas prĂłteses realizadas na tĂbia proximal em comparação com o fĂŞmur distal (57,1% x 42,9%). O seguimento mĂŠdio dos pacientes foi 68,2 meses. Durante o seguimento, um paciente faleceu devido a doença de base. Dos sete pacientes, 6 foram considerados curados e um persistiu com sinais e sintomas de infecção. CONCLUSĂO: Os resultados obtidos atĂŠ o momento tem motivado a continuidade deste mĂŠtodo de tratamento.Universidade Federal de SĂŁo Paulo (UNIFESP) Escola Paulista de Medicina Departamento de Ortopedia e TraumatologiaUNIFESP, EPM, Depto. de Ortopedia e TraumatologiaSciEL

Massive rotator cuff tears: functional outcome after debridement or arthroscopic partial repair
Background The surgical treatment of massive rotator cuff tears (RCT) is still controversial and can be based on a variety of different surgical repair methods. This study investigated the effectiveness of arthroscopic debridement or arthroscopic partial repair in patients with massive RCT. Materials and methods This prospective, randomized study involved forty-two patients with massive RCT (fatty infiltration stage 3 or 4) treated with either arthroscopic partial repair or arthroscopic debridement were selected to detect possible differences in functional outcome. Both groups were matched according to age and gender. Patients were examined before, and 16 Âą 3 and 24 Âą 2 months after surgery. The status of the rotator cuff repair was determined using ultrasonographic evaluation. Results Regardless of the treatment group, postoperative results demonstrated highly significant improvements compared with preoperative values in most parameters. The overall Constant score in the partial repair group was superior to the outcome in the debridement group (P \ 0.01, F = 8.561), according to better results in abductio
Azimuthal anisotropy of charged particles at high transverse momenta in PbPb collisions at sqrt(s[NN]) = 2.76 TeV
The azimuthal anisotropy of charged particles in PbPb collisions at
nucleon-nucleon center-of-mass energy of 2.76 TeV is measured with the CMS
detector at the LHC over an extended transverse momentum (pt) range up to
approximately 60 GeV. The data cover both the low-pt region associated with
hydrodynamic flow phenomena and the high-pt region where the anisotropies may
reflect the path-length dependence of parton energy loss in the created medium.
The anisotropy parameter (v2) of the particles is extracted by correlating
charged tracks with respect to the event-plane reconstructed by using the
energy deposited in forward-angle calorimeters. For the six bins of collision
centrality studied, spanning the range of 0-60% most-central events, the
observed v2 values are found to first increase with pt, reaching a maximum
around pt = 3 GeV, and then to gradually decrease to almost zero, with the
decline persisting up to at least pt = 40 GeV over the full centrality range
measured.Comment: Replaced with published version. Added journal reference and DO
