Practical Guidance on the Detection of NTRK Fusions in Sarcomas: Current Status...
Fernandes, I; Macedo, D; Gouveia, E; Ferreira, A; Lima, J; Lopez, D; Melo-Alvim, C; Carvalho, A; Tavares, P; Rodrigues-Santos, P; Cardoso, PSarcomas are a rare and heterogeneous group of mesenchymal malignant tumors and account for approximately 1% of all adult cancers and around 20% of all pediatric solid tumors in Europe. Technology advances have enabled a more accurate and efficient characterization of the molecular mechanisms underlying the pathogenesis of sarcoma subtypes and revealed novel and unexpected therapeutic targets with prognostic/pr...
Chronic Intestinal Failure and Short Bowel Syndrome in Adults: The State of the...
Vara-Luiz, F; Glória, L; Mendes, I; Carlos, S; Guerra, P; Nunes, G; Oliveira, CS; Ferreira, A; Santos, AP; Fonseca, JBackground: Short bowel syndrome (SBS) is a devastating malabsorptive condition and the most common cause of chronic intestinal failure (CIF). During the intestinal rehabilitation process, patients may need parenteral support for months or years, parenteral nutrition (PN), or hydration/electrolyte supplementation, as a bridge for the desired enteral autonomy. Summary: Several classification criteria have been h...
The effect of the attitude towards risk/ambiguity on examination grades: cross-...
Leite-Mendes, F; Delgado, L; Ferreira, A; Severo, MGiven the high prevalence of multiple-choice examinations with formula scoring in medical training, several studies have tried to identify other factors in addition to the degree of knowledge of students which influence their response patterns. This study aims to measure the effect of students’ attitude towards risk and ambiguity on their number of correct, wrong, and blank answers. In October 2018, 233 3rd yea...
Hypomagnesemia: a Potential Underlooked Cause of Persistent Vitamin D Deficienc...
Matias, P; Ávila, G; Ferreira, AC; Laranjinha, I; Ferreira, AMagnesium and vitamin D play important roles in most cells of the body. These nutrients act in a coordinated fashion to maintain physiologic functions of various organs, and their abnormal balance could adversely affect these functions. Therefore, deficient states of both nutrients may lead to several chronic medical conditions and increased cardiovascular and all-cause mortality. Chronic kidney disease (CKD) p...
Application of Optical Coherence Tomography Angiography for Microvascular Chang...
Ferreira, A; Anjos, R; José-Vieira, R; Afonso, M; Abreu, AC; Monteiro, S; Macedo, M; Andrade, J; Furtado, MJ; Lume, MBackground: Retinal toxicity with long-term hydroxychloroquine (HCQ) treatment is a major concern. This systematic review aims to assess the application of optical coherence tomography angiography (OCTA) to detect microvascular alterations in patients under HCQ. Methods: PubMed, Scopus, Web of Science, and Cochrane Library databases were systematically searched until January 14, 2023. Studies using OCTA as a pr...
Pancreas Rejection in the Artificial Intelligence Era: New Tool for Signal Pati...
Vigia, E; Ramalhete, L; Ribeiro, R; Barros, I; Chumbinho, B; Filipe, E; Pena, A; Bicho, L; Nobre, A; Carrelha, S; Sobral, M; Lamelas, J; Coelho, JSIntroduction: Pancreas transplantation is currently the only treatment that can re-establish normal endocrine pancreatic function. Despite all efforts, pancreas allograft survival and rejection remain major clinical problems. The purpose of this study was to identify features that could signal patients at risk of pancreas allograft rejection. Methods: We collected 74 features from 79 patients who underwent simu...
Utility of Prophylactic Percutaneous Gastrostomy in Patients With Head and Neck...
Neves, MT; Ferreira, A; Branco, V; Abreu, M; Alves, FR; Baptista, C; Graça, J; Ferreira, F; Malheiro, M; Martins, AIntroduction: Patients with head and neck cancer (HNC) have an elevated incidence of cachexia and malnutrition due to the tumor's location interfering with oral feeding. Concurrent chemoradiation (CCRT) can have an emetic effect and cause dysphagia and oral mucositis. Adequate nutrition improves immunity, raises the response to therapy, reduces adverse effects, and improves survival. Numerous studies have sugge...
Complete blood count parameters as biomarkers of retinopathy of prematurity: a ...
Fevereiro-Martins, M; Santos, AC; Marques-Neves, C; Guimarães, H; Bicho, M; Afonso, C; Ferreira, J; Espírito Santo, R; Teixeira, F; Rosa, RPurpose: To evaluate complete blood count (CBC) parameters in the first week of life as predictive biomarkers for the development of retinopathy of prematurity (ROP). Methods: Multicenter, prospective, observational study of a cohort of preterm infants born with gestational age (GA) < 32 weeks or birth weight < 1500 g in eight Portuguese neonatal intensive care units. All demographic, clinical, and laboratory d...
Adenovirus Infection in a Kidney–Pancreatic Transplant Recipient: Case Report
Damas, J; Vida, AC; Marques, J; Caeiro, F; Aires, I; Dias, JM; Bigotte Vieira, M; Cotovio, P; Magriço, R; Ferreira, AAdenovirus infection in transplant recipients may present from asymptomatic viremia to multisystemic involvement. Most frequently, it occurs in the first year after a kidney transplant, and it is secondary to the reactivation of latent disease. However, primary infection may occur, and disseminated disease is more common when related to primary infection. Kidney involvement may be confirmed by biopsy, although ...
Heterotopic Caval Valve-in-Valve Procedure for Prosthetic Migration: Two Case R...
Grazina, A; Ferreira, A; Ramos, R; Cacela, DBackground: Heterotopic bicaval stenting or caval valve implantation (CAVI) either with non-dedicated balloon-expandable Sapien™ valves (Edwards Lifesciences) or with dedicated TricValve™ (Products + Features) has emerged as a safe and effective percutaneous treatment for high-risk patients with severe tricuspid regurgitation (TR). One technical difficulty of CAVI is the lack of native calcified structures to a...
