Diaphragm ultrasound for muscle strength assessment: A systematic literature re...
Leote, Joao; Monteiro, Margarida; Rocha, Cláudia; Rodrigues, Carolina; Pereira, Marco; Antunes, Maria Luz; Dias, Hermínia; Antunes, Maria da LuzObjective: To assess if diaphragmatic ultrasound (DU) reflects diaphragmatic muscle strenght when compared to respiratory tests and neurophysiological studies. Methods: A systematic literature review was conducted on adults undergoing DU, compared to any respiratory or neurophysiological technique. The search strategy was applied in PubMed, Scopus, and Web of Science, and the analysis was conducted using the PR...
Total signal intensity of ultrasound laboratory vertical artifacts: a semi-quan...
Leote, Joao; Loução, Ricardo; Aguiar, Madalena; Tavares, Mariana; Ferreira, Paloma; Muxagata, Tiago; Guerreiro, Diana; Dias, Hermínia BritesQuantitative approaches to improve lung ultrasound (LUS) vertical artifacts (VA) interpretation using total signal intensity (ITOT) are not widely available for clinical practice. In this study, we aimed to i) develop a mathematical algorithm to extract ITOT as a post-hoc LUS analysis and ii) confirm ITOT utility by conducting laboratory VA research using an in vitro model with different acoustic channels. The ...
Considerações de anestesiologia na eletroconvulsoterapia.
Leote, JoaoIntrodução A eletroconvulsoterapia (ECT) é um procedimento com um papel insubstituível no tratamento de patologias graves do foro psiquiátrico. No entanto, possui efeitos adversos relacionados com a estimulação elétrica transcraniana, pelo que é realizado sob anestesia geral. O presente trabalho pretende descrever e rever os cuidados de anestesiologia peri-procedimento para otimização de segurança e eficácia ...
Influence of ultrasound settings on laboratory vertical artifacts
Leote, Joao; Muxagata, Tiago; Guerreiro, Diana; Francisco, Cláudia; Dias, Hermínia Brites; Loução, Ricardo; Bacariza, Jacobo; Gonzalez, FilipeObjective: The aim of the work described here was to analyze the relationship between the change in ultrasound (US) settings and the vertical artifacts' number, visual rating, and signal intensity METHODS: An in vitro phantom consisting of a damp sponge and gelatin mix was created to simulate vertical artifacts. Furthermore, several US parameters were changed sequentially (i.e., frequency, dynamic range, line d...
Combined brain language connectivity and intraoperative neurophysiologic techni...
Leote, JoaoSpeech processing can be disturbed by primary brain tumors (PBT). Improvement of presurgical planning techniques decrease neurological morbidity associated to tumor resection during awake craniotomy. The aims of this work were: 1. To perform Diffusion Kurtosis Imaging based tractography (DKI-tract) in the detection of brain tracts involved in language; 2. To investigate which factors contribute to functional ma...
