Pancreatectomy with En Bloc Superior Mesenteric Vein and All Its Tributaries Resection without PV/SMV Reconstruction for "Low" Locally Advanced Pancreatic Head Cancer.

The "vein definition" for locally advanced pancreatic ductal adenocarcinoma (LA PDAC) assumes portal-to-superior mesenteric vein (PV/SMV) unreconstructability due to tumor involvement or occlusion. Radical pancreatectomies with SMV resection without PV/SMV reconstruction are scarcely discussed in the literature. Retrospective analysis of 19 radical pancreatectomies for "low" LA PDAC with SMV and all its tributaries resection without PV/SMV reconstruction has shown zero mortality; overall morbidity-56%; Dindo-Clavien-3-10.

The predictive potential of autoimmune-inflammatory syndrome induced by adjuvants (ASIA) criteria to assess the risk of adverse events and efficacy of immune checkpoint inhibitor therapy.

At the moment, there are no approved predictive markers of immune adverse events (irAES) induced by immune checkpoint inhibitors (ICIs) and the treatment efficacy. The early stages of irAES have some similarities with adjuvant-induced autoimmune/pro-inflammatory syndrome (ASIA). This study aims to assess the predictive possibility of using the "ASIA questionnaire" in patients on immune checkpoint inhibitor therapy in comparison with determination of PD-L1 expression to predict the risk of irAES development and therapy efficacy.

The Novel Diagnostic Index Based on HLA-DRB1 Genotype and PD-L1 Expression can Predict Severe irAEs in Patients with Metastatic Melanoma Taking Immune Checkpoint Inhibitors. The Results of the Pilot Study.

Immune-related adverse events (irAEs) occur in up to 50% of patients treated with an anti-CTLA-4 antibody and 30% of patients treated with PD-1/PD-L1 antibodies. Severe forms of toxicity are observed in 3% of patients and require systemic steroid therapy and constant monitoring. One of the considered predictor biomarkers of irAEs development is HLA-genotypes.

Case report of mild form of a new coronavirus infection in patient with idiopathic pulmonary hypertension.

The article presents a clinical case of mild novel coronavirus infection COVID-19 complicated with bilateral interstitial pneumonia in a female patient with idiopathic pulmonary hypertension.

Correlations between clinical and laboratory findings and prognostically unfavorable CMR-based characteristics of acute ST-elevation myocardial infarction.

Aim To evaluate factors associated with unfavorable predictive characteristics of ST-segment elevation acute myocardial infarction (STEMI) as per data of magnetic resonance imaging (MRI).Material and methods The study included 52 patients with STEMI who underwent a primary percutaneous coronary intervention (pPCI). Contrast-enhanced cardiac MRI was performed for all patients on days 3-7.

[The State of Vascular Bed, Parenchyma and Perfusion of Lungs in Chronic Thromboembolic Pulmonary Hypertension According to Data of Subtraction Pulmonary Angiography].

Aim: to assess the state of vascular bed, parenchyma, and perfusion of lungs in patients with chronic thromboembolic pulmonary hypertension (CTEPH) using the method of subtraction computed tomography (CT).

Methods: CT pulmonary angiography (CTPA) was performed in 45 patients with verified CTEPH (18 men, 27 women, age 26-79 years) by CT scanner using the "Lung subtraction" standard protocol. Parameters analyzed were characteristics of the state of main pulmonary artery (MPA) and the right ventricle (RV), and calculated CT angiographic (CTA) obstruction and perfusion defect scores.

[Subtraction CT angiopulmonographic assessment of the vascular bed and lung perfusion in patients with chronic thromboembolic pulmonary hypertension: A pilot study].

Aim: To evaluate the vascular bed and lung perfusion in patients with chronic thromboembolic pulmonary hypertension (CTEPH) by computed tomography (CT) and to compare the severity of pulmonary arterial (PA) thrombotic lesions concurrent with parenchymal perfusion disorders with angiopulmonographic findings and clinical and hemodynamic characteristics.

Subjects And Methods: In the period from November 2015 to May 2016, 22 patients (7 men, 15 women) aged 27 to 67 years with a verified diagnosis of CTEPH were examined using an Aquilion ONE VISION Edition 640 (Toshiba Medical Systems, Japan) CT scanner with a 320-row detector. Perfusion defect in this study was evaluated with the new software allowing one to combine contrast and contrast-free images by a subtraction method.
