- Early glycemic control and incretin improvement after gastric bypass: the role of oral and gastrostomy route(2019) FERNANDES, Gustavo; SANTO, Marco Aurelio; CRESPO, Andrea de Fatima Crispino Bastos; BIANCARDI, Gabriel Barbosa; MOTA, Filippe Camarotto; ANTONANGELO, Leila; CLEVA, Roberto deBackground: Patients with obesity have a suppressed incretin effect and a consequent imbalance of glycemic homeostasis. Several studies have shown improved type 2 diabetes after Roux-en-Y gastric bypass (RYGB). The mechanisms of early action are linked to caloric restriction, improvement of insulin resistance, pancreatic beta cell function, and the incretin effect of glycogen-like protein 1 and gastric inhibitory polypeptide, but reported data are conflicting. Objective: The objective of this study was to evaluate glycemic metabolism, including the oral glucose tolerance test and enterohormonal profile in the early postoperative period in severely obese patients who underwent RYGB with gastrostomy, comparing the preoperative supply of a standard bolus of nutrient against the postoperative administration through an oral and a gastrostomy route. Setting: Clinics Hospital of University of Sao Paulo, Brazil. Methods: Eleven patients with obesity and diabetes underwent RYGB with a gastrostomy performed in the excluded gastric remnant. Patients were given preoperative assessments of glycemic and enterohormone profiles and an oral glucose tolerance test; these were compared with early postoperative assessments after oral and gastrostomy route administrations. Results: The mean preoperative body mass index of the group was 44.1 +/- 6.6 kg/m(2), mean fasting blood glucose of 194.5 +/- 62.4 mg/dL, and glycated hemoglobin 8.7 +/- 1.6%. In 77.7% of the patients, there was normalization of the glycemic curve in the early postoperative period as evaluated by the oral glucose tolerance test. Significant decreases in glycemia, insulinemia, and homeostatic model assessment-insulin resistance were also observed, regardless of the route of administration. There was significant increase in glycogen-like protein 1 by the postoperative oral route and reduction of gastric inhibitory polypeptide in both routes. Ghrelin did not change. Conclusion: Glycemia and peripheral insulin resistance reductions were observed in early postoperative RYGB, independent of the oral or gastrostomy route. Incretin improvement, mediated by glycogen-like protein 1 increased was observed only in the postoperative oral route, while GIP reduced for both routes.

conferenceObject Usefulness of type V collagen and alpha 2 beta 1-integrin in the cytological diagnosis of pleural liquid biopsy(2019) ANTONANGELO, L.; TEODORO, W. Rosolia; FARIA, C. Silverio; QUEIROZ, Z. A.; SILVEIRA, L. Ramos da; VELOSA, A. P.; CAPELOZZI, V.- Tuberculous pleural effusion: diagnosis & management(2019) ANTONANGELO, Leila; FARIA, Caroline S.; SALES, Roberta K.Background: Tuberculosis (TB) is the world's leading cause of death from infectious disease. The World Health Organization (WHO) recognized 6.3 million new TB cases in 2017, 16% corresponding to extrapulmonary forms; pleural tuberculosis (PT) is the most common extrapulmonary form in adults. PT diagnosis is often challenging because the scarcity of bacilli in pleural fluid (PF), sometimes requiring invasive procedures to obtain pleural tissue for histological, microbiological or molecular examination. In regions of medium and high disease prevalence, adenosine deaminase (ADA), interferon gamma (IFN-gamma) and interleukin 27 (IL-27) dosages are useful to establish presumptive diagnosis in patients with compatible clinical/radiological picture who present with lymphocytic pleural effusion. PT treatment is similar to the pulmonary TB treatment regimen recommended by WHO. Area covered: In this update, we present a PT review, including epidemiology, pathogenesis, clinical features, diagnosis, and therapy. Expert opinion: There is no PF test alone accurate for PT diagnosis, despite the evolution in clinical laboratory. ADA, IFN-gamma and IL-27 are valuable laboratory biomarkers; however, IFN-gamma and IL-27 are quite expensive. Molecular tests present low sensitivity in PF, being useful for diagnostic confirmation. Multidrug therapy remains the PT treatment choice. Advancing research in immunotherapy may bring benefits to PT patients.

- Hybrid panel of biomarkers can be useful in the diagnosis of pleural and peritoneal effusions(2019) FARIA, Daniel K.; FARIA, Caroline S.; DOI, Dimitria; ACENCIO, Milena M. P.; ANTONANGELO, LeilaBackground: In clinical practice, pleural and peritoneal effusions are usual diagnosis. We evaluated the performance of a hybrid panel of biomarkers in the diagnosis of the main diseases affecting pleura and/or peritoneum. Methods: Samples of pleural/ peritoneal fluid from 120 patients were evaluated for: CEA (carcinoembryonic antigen), VEGF-A (vascular endothelial growth factor A), PD-L1/B7-H1 (programmed death-ligand 1), NGAL (neutrophil gelatinase-associated lipocalin), TREM-1 (triggering receptor expressed in myeloid cells type-1) and IFN gamma (gamma-interferon) by Luminex (R); CALP (Calprotectin) by ELISA, and ADA (adenosine deaminase) by enzymatic deamination. Results: For malignant effusion (ME) diagnosis, CEA and NGAL presented superior performance than VEGF-A, PD-L1 and CALP. A CEA-NGAL association showed good sensitivity (86.6%) and accuracy (79.2%). For non-tuberculous infectious effusion (NTBIE), NGAL presented the best performance with sensitivity (75.0%), specificity (62.0%) and accuracy (65.0%) higher than TREM-1 and CALP; however, when associated, although with good sensitivity, there was important decrease in specificity. For tuberculous pleural effusion (TPE), IFNy-ADA presented excellent sensitivity (100%), specificity (87.6%), NPV (100%) and accuracies (similar to 90%). Conclusions: CEA, NGAL, ADA and IFNy were useful in discriminating ME and TPE. However, for NTBIE diagnosis, the hybrid panel did not demonstrate advantages over the classic parameters.

Oliveira da; NASCIMENTO, A. Mendes; CARVALHO, G. Francisco da Silva; DIAS, A. Torchio; KULIKOWSKI, L. Domenici- Transient abnormal myelopoiesis with pericardial effusion in Down syndrome: Case report(2019) FALASCO, Bianca Francisco; DURANTE, Brenda; FARIA, Daniel Kanaan; FARIA, Caroline Silveri; ROSOLEN, Debora Cristina Batista; ANTONANGELO, LeilaPericardial effusion associated with transient abnormal myelopoiesis in Down's syndrome neonates needs to be diagnosed in a timely manner, and the comorbidities must be treated to prevent mortality. To our knowledge, the occurrence of basophilic/eosinophilic pericardial effusion without an increase of these cells in the peripheral blood and with no evidence of associated hypothyroidism is rare.
