Integration of FTIR Spectroscopy and Machine Learning for Kidney Allograft Reje...
Ramalhete, Luís; Araújo, Rúben; Bigotte Vieira, Miguel; Vigia, Emanuel; Aires, Inês; Ferreira, Anibal; Calado, CecíliaPublisher Copyright: © 2025 by the authors.; Background: Kidney transplantation is a life-saving treatment for end-stage kidney disease, but allograft rejection remains a critical challenge, requiring accurate and timely diagnosis. The study aims to evaluate the integration of Fourier Transform Infrared (FTIR) spectroscopy and machine learning algorithms as a minimally invasive method to detect kidney allograft...

Lafage-Proust, Marie-Helene; Jørgensen, Hanne Skou; Bravenboer, Nathalie; Ferreira, Anibal; Bégin, Marie-Josée; Cannata-Andia, Jorge; Cejka, DanielHistomorphometric analysis of an iliac bone biopsy remains the gold standard for the diagnosis of renal osteodystrophy (ROD), which comprises various histological lesions induced by chronic kidney disease (CKD). ROD belongs to the framework of CKD-associated osteoporosis. The use of bone biopsy in the routine management of CKD-associated osteoporosis has decreased over the past decades for various reasons, incl...
Predicting Cellular Rejection of Renal Allograft Based on the Serum Proteomic F...
Ramalhete, Luís; Vieira, Miguel Bigotte; Araújo, Rúben; Vigia, Emanuel; Aires, Inês; Ferreira, Anibal; Calado, CecíliaPublisher Copyright: © 2024 by the authors.; Kidney transplantation is an essential medical procedure that significantly enhances the survival rates and quality of life for patients with end-stage kidney disease. However, despite advancements in immunosuppressive therapies, allograft rejection remains a leading cause of organ loss. Notably, predictions of cellular rejection processes primarily rely on biopsy an...
What recovery position should patients adopt after percutaneous liver biopsy?
Costa, Rita S.; Cardoso, Ana F.; Ferreira, Anibal; Costa, Juliana; Costa, Dalila Amélia Amorim; Fernandes, Dália; Caetano, Ana C.Introduction Percutaneous liver biopsy (PLB) is an invasive procedure used for the assessment of liver diseases. The patient’s recovery position after the PLB differs among hospitals and departments. This study aims to evaluate adverse events and patient acceptability according to the recovery position adopted after the PLB. Patients and methods From September 2014 to March 2017, patients submitted to PLB were ...
An uncommon diagnosis done by colonoscopy
Costa, Rita Seara; Costa, Juliana M.; Ferreira, Anibal; Gonçalves, Raquel; Rolanda, Carla[Excerpt] A 74-year-old woman with a previous history of alcoholism and chronic subdural hematoma presented at the emergency department with a lipothymia. No recent trauma was noticed. She was in a hemodynamically stable condition (blood pressure, 100/50 mm Hg; heart rate, 96 bpm).[...]
Higher mineralized bone volume is associated with a lower plain X-Ray vascular ...
Adragao, Teresa; Ferreira, Anibal; Frazão, João; Papoila, Ana Luisa; Pinto, Iola; Monier-Faugere, Marie-Claude; Malluche, Hartmut H.Background and objectives In dialysis patients, there is an increasing evidence that altered bone metabolism is associated with cardiovascular calcifications. The main objective of this study was to analyse, in hemodialysis patients, the relationships between bone turnover, mineralization and volume, evaluated in bone biopsies, with a plain X-ray vascular calcification score. Design, setting, participants and m...
Interobserver agreement of EUS elastography in the evaluation of solid pancreat...
Soares, João-Bruno; Iglesias-Garcia, Julio; Goncalves, Bruno; Lindkvist, Björn; Lariño-Noia, Jose; Bastos, Pedro; Caetano, Ana Célia; Ferreira, AnibalPrevious reports assessing the reproducibility of endoscopic ultrasound elastography (EUS-E) in evaluation of solid pancreatic lesions (SPL) involved only experienced endosonographers. We aimed to assess the interobserver agreement (IOA) of EUS-E in the evaluation of SPL by endoscopists with different levels of experience in EUS and EUS-E.
Concatenative singing voice resynthesis
Fonseca, Nuno; Ferreira, Anibal; Rocha, Ana PaulaThe concept of capturing the sound of “something” for later replication is not new, and it is used in many synthesizers. But capturing sounds and use them as an audio effect, is less common. This paper presents an approach for the resynthesis of a singing voice, based on concatenative techniques, that uses pre-recorded audio material as an high level semantic audio effect, replacing an original audio recording ...
