- Acute fibrinous and organizing pneumoniaPublication . Santos, C; Fradinho, F; Catarin0, AThe histologic pattern of Acute Fibrinous and Organizing Pneumonia (AFOP), described by Beasley in 2002, is characterized by the existence of intra alveolar fibrin in the form of fibrin "balls" and diffuse organizing pneumonia. Presenting symptoms of this interstitial pulmonary disease can be acute or subacute. However, it differs from the well -recognized histologic patterns of acute pulmonary lesion - Diffuse Alveolar Damage (DAD), Organizing Pneumonia (OP) and Eosinophilic Pneumonia (EP). The authors carry out a review of the literature concerning this topic and describe the clinical case of a 44 -year -old patient with unusual imaging features and outcome
- Deciduoid Pleural Mesothelioma - a Rare Entity in a Young WomanPublication . Santos, C; Gamboa, F; Fradinho, F; Pêgo, A; Carvalho, L; Bernardo, JDeciduoid Mesothelioma is a rare variant of epithelioid mesothelioma; it was initially thought that it only occurred in the peritoneum of young women and had nothing to do with asbestos exposure. However, since these early findings it has also been observed in the pleura and the pericardium, with possible association to asbestos. In general the prognosis is poor compared to epithelioid mesothelioma. 45 cases have been reported in the literature up to now, 22 of these were located in the pleural cavity. The authors describe a case of deciduoid pleural mesothelioma in a 40-year-old-woman who presented with right pleuritic chest pain, with no history of asbestos exposure, treated with chemotherapy followed by surgery and who died postoperatively.

- Peripheral biomarkers to diagnose obstructive sleep apnea in adults: A systematic review and meta-analysisPublication . Gaspar, LS; Santos-Carvalho, A; Santos, B; Carvalhas-Almeida, C; Barros-Viegas, AT; Oliveiros, B; Donato, H; Santos, C; Moita, J; Cavadas, C; Álvaro, ARBackground: Obstructive Sleep Apnea (OSA) has been recognized as a major health concern worldwide, given its increasing prevalence, difficulties in diagnosis and treatment, and impact on health, economy, and society. Clinical guidelines highlight the need of biomarkers to guide OSA clinical decision-making, but so far, without success. In this systematic review and meta-analysis, registered on the International Prospective Register of Systematic Reviews database (ID CRD42020132556), we proposed to gather and further explore candidates identified in the literature as potential OSA biomarkers. Methods: Search strategies for eight different databases (PubMed/Medline, Cochrane Library, Biblioteca Virtual da Saúde, Web of Science, EMBASE, World Intellectual Property Organization database, and bioRxiV and medRxiV Preprint Servers) were developed. We identified studies exploring potential biomarkers of OSA, in peripheral samples of adults, with and without OSA, with no comorbidities defined in study inclusion criteria, published after the last systematic review and meta-analysis conducted on OSA biomarkers, until May 31st, 2020. Risk of bias was assessed through the 14-item Quality Assessment Tool for Diagnostic Accuracy Studies. Demographic, clinical, and candidate biomarkers' data were collected and analyzed via random effects meta-analyses. Findings: Among the 1512 unique studies screened, 120 met the inclusion criteria and 16 studies with low risk of bias were selected for meta-analyses. The selected 16 studies enrolled a total of 2156 participants, from which 1369 were diagnosed with OSA and 787 were disease-free controls. The assessed variables showed high heterogeneity. From the 38 biomarker candidates evaluated, only two were evaluated in more than one study. Most studies pinpointed candidates with more potential for OSA prognosis. ADAM29, FLRT2 and SLC18A3 mRNA levels in PBMCs, Endocan and YKL-40 levels in serum, and IL-6 and Vimentin levels in plasma revealed the most promising candidates for OSA diagnosis. Interpretation: Although the current systematic review and meta-analysis allowed us to identify candidates to further explore as potential biomarkers in future studies, it is evident that OSA biomarkers research is still at an early stage. Most findings derive from small-size single-center study cohorts and single-candidate studies. We point several gaps in current OSA biomarker research that may guide into new directions and approaches towards the identification of OSA biomarkers.
