Cumulus cell DNA damage linked to fertilization success in females with an ovul...
Rodrigues, B; Sousa, V; Esteves, F; Vale-Fernandes, E; Costa, S; Sousa, D; Brandão, R; Leal, C; Pires, J; Gaivão, I; Teixeira, JP; Nogueira, AJAIntracytoplasmic sperm injection (ICSI) is a widely used technique in fertility centers. ICSI success depends on both nuclear and cytoplasmic oocyte maturation. Cumulus cells, which surround the oocytes, play a pivotal role in oocyte competence. However, the significance of DNA damage in cumulus cells as a marker of fertilization success remains largely unexplored. This study aims to investigate the relationshi...
Contextual Hospital Conditions and the Risk of Nosocomial SARS-CoV-2 Infection:...
Almeida, F; Correia, S; Leal, C; Guedes, M; Duro, R; Andrade, P; Pedrosa, A; Rocha-Pereira, N; Lima-Alves, C; Azevedo, AObjective: Knowledge of the role of hospital conditions in SARS-CoV-2 transmission should inform strategies for the prevention of nosocomial spread of this pathogen and of similarly transmitted viruses. This study aimed to identify risk factors for nosocomial acquisition of SARS-CoV-2. Methods: We ran a nested case-control study with incidence density sampling among adult patients hospitalized for >7 days (Augu...
Increase of Antimicrobial Consumption in a Tertiary Care Hospital during the Fi...
Castro-Lopes, A; Correia, S; Leal, C; Resende, I; Soares, P; Azevedo, A; Paiva, JABackground: The COVID-19 pandemic poses novel challenges in antimicrobial consumption metrics and stewardship strategies. COVID-19 patients became the major cause of hospital admission during the first wave of the pandemic, often leading to an antimicrobial prescription upon admission or treatment for superinfections. The aim of this study was to understand how antimicrobial consumption was impacted at the begi...
Does the association of prostate cancer with night-shift work differ according ...
Mancio, J; Leal, C; Ferreira, M; Norton, P; Lunet, NBackground: Recent studies suggested that the relation between night-shift work and prostate cancer may differ between rotating and fixed schedules. Objectives: We aimed to quantify the independent association between night-shift work and prostate cancer, for rotating and fixed schedules. Methods: We searched MEDLINE for studies assessing the association of night-shift work, by rotating or fixed schedules, with...
Idiopathic Pulmonary Fibrosis in the Era of Antifibrotic Therapy: Searching for...
Robalo-Cordeiro, C; Campos, P; Carvalho, L; Borba, A; Clemente, S; Freitas, S; Furtado, S; Jesus, JM; Leal, C; Marques, A; Melo, N; Souto-Moura, CIdiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease that up to now has been associated with a poor prognosis. However, the results of the INPULSIS and ASCEND trials and the approval of nintedanib and pirfenidone have marked the beginning of a new era for IPF patients. Questions remain, however. Should these drugs be used earlier? What effect will they have on more severe disease? Will th...
The Utility of Apparent Diffusion Coefficient Values in the Risk Stratification...
Lopes Dias, J; Magalhães Pina, J; Vasco Costa, N; Carmo, S; Leal, CPurpose: To evaluate the relationship between mean apparent diffusion coefficient (ADC) and post-surgical Gleason scores. To determine the diagnostic accuracy of multiparametric magnetic resonance imaging (mp-MRI) on a 1.5 T magnet in distinguishing low, intermediate and highgrade prostate tumors. Material and methods: This is a retrospective institutional-review-board-approved, singlecenter study including 30 ...
Bailout Intravenous Esmolol for Heart Rate Control in Cardiac Computed Tomograp...
Rosa, S; Ramos, R; Marques, H; Santos, R; Leal, C; Casado, H; Saraiva, M; Figueiredo, L; Cruz Ferreira, ROBJECTIVE: To evaluate the efficacy and safety of a heart rate (HR) reduction protocol using intravenous esmolol as bailout for failed oral metoprolol regimens in patients undergoing coronary computed tomography angiography (CCTA) with 64-slice multidetector computed tomography (64-MDCT). METHODS: Patients who underwent cardiac 64-MDCT in a single institution between 2011 and 2014 were analyzed. Those with HR a...
Post-Treated Prostate Cancer: Normal Findings and Signs of Local Relapse on Mul...
Lopes Dias, J; Lucas, R; Pina, J; João, R; Costa, N; Leal, C; Bilhim, T; Campos Pinheiro, L; Mateus Marques, RThe use of multiparametric magnetic resonance imaging (mp-MRI) for prostate cancer has increased over recent years, mainly for detection, staging, and active surveillance. However, suspicion of recurrence in the set of biochemical failure is becoming a significant reason for clinicians to request mp-MRI. Radiologists should be able to recognize the normal post-treatment MRI findings. Fibrosis and atrophic remna...
Thoracic Manifestations of Connective Tissue Diseases
Ruano, C; Lucas, R; Leal, C; Lourenço, J; Pinheiro, S; Fernandes, O; Figueiredo, LConnective tissue diseases (CTDs) comprise several immunologic systemic disorders, each of which associated with a particular set of clinical manifestations and autoimmune profile. CTDs may cause numerous thoracic abnormalities, which vary in frequency and pattern according to the underlying disorder. The CTDs that most commonly involve the respiratory system are progressive systemic sclerosis, systemic lupus e...
Prostate Cancer: The Role of Multiparametric Magnetic Resonance Imaging
Lopes Dias, J; Pina, J; João, R; Fialho, J; Carmo, S; Leal, C; Bilhim, T; Mateus Marques, R; Campos Pinheiro, LMultiparametric Magnetic Resonance Imaging has been increasingly used for detection, localization and staging of prostate cancer over the last years. It combines high-resolution T2 Weighted-Imaging and at least two functional techniques, which include Dynamic Contrast–Enhanced Magnetic Resonance Imaging, Diffusion-Weighted Imaging, and Magnetic Resonance Imaging Spectroscopy. Although the combined use of a pelv...
