Chronic Chest Pain Control after Trans-Thoracic Biopsy in Mediastinal Lymphomas.

Healthcare (Basel) 2021 May 18;9(5). Epub 2021 May 18.

Pain Department, AORN Dei Colli-V. Monaldi, 80131 Naples, Italy.

Chest pain following a trans-thoracic biopsy often has multiple etiologies, especially in patients with lymphomas. Pathological neuronal mechanisms integrate with an overproduction of IL-6, TNF-α, IL1-β by macrophages and monocytes, which amplifies inflammation and pain. In consideration of this complex pathogenesis, international guidelines recommend diversified analgesia protocols: thoracic epidural, paravertebral block, and systemic administration of opioids.

Acute pulmonary hypertension and short-term outcomes in severe Covid-19 patients needing intensive care.

Acta Anaesthesiol Scand 2021 Jul 27;65(6):761-769. Epub 2021 Mar 27.

Department of Physiology and Pharmacology, Section of Anaesthesiology and Intensive Care, Karolinska Institutet, Stockholm, Sweden.

Introduction: Critically ill Covid-19 pneumonia patients are likely to develop the sequence of acute pulmonary hypertension, right ventricular (RV) strain, and eventually RV failure due to known pathophysiology (endothelial inflammation plus thrombo-embolism) that promotes increased pulmonary vascular resistance and pulmonary artery pressure. This study aimed to investigate the occurrence of acute pulmonary hypertension (aPH) as per established trans-thoracic echocardiography (TTE) criteria in Covid-19 patients receiving intensive care and to explore whether short-term outcomes are affected by the presence of aPH.

Methods: Medical records were reviewed for patients treated in the intensive care units at a tertiary university hospital over a month. Read More

Non-invasive, model-based measures of ventricular electrical dyssynchrony for predicting CRT outcomes.

Europace 2016 Dec;18(suppl 4):iv104-iv112

Department of Bioengineering, University of California, 9500 Gilman Drive, La Jolla, San Diego, CA 92093-0412, USA
