Venous Thromboembolism in Patients With Atrial Fibrillation: A Systematic Review and Meta-Analysis of 4,170,027 Patients.

Background: Data on the association between atrial fibrillation (AF) and venous thromboembolism (VTE) are controversial.

Objectives: The purpose of this study was to investigate the risk of VTE in patients with AF according to the time from AF diagnosis.

Methods: Systematic review of MEDLINE (PubMed), Embase, Cumulative Index to Nursing and Allied Health Literature (EBSCO host), Cochrane Central Register of Controlled Trials (2020) in the Cochrane Library, and World Health Organization Global Index Medicus databases and meta-analysis of observational studies.

Acute upper and lower gastrointestinal bleeding management in older people taking or not taking anticoagulants: a literature review.

Acute upper and lower gastrointestinal (GI) bleeding may be a potentially life-threatening event that requires prompt recognition and an early effective management, being responsible for a considerable number of hospital admissions. Methods. We perform a clinical review to summarize the recent international guidelines, helping the physician in clinical practice.

COVID-Vaccines in Pregnancy: Maternal and Neonatal Response over the First 9 Months after Delivery.

Vaccination against SARS-CoV-2 has been demonstrated to be safe during gestation. Nevertheless, there are no robust data investigating the entity of maternal antibodies' transmission through the placenta to the newborn and the persistence of the antibodies in babies' serum. The objective of this study is to assess the maternal antibody transmission and kinetics among newborns in the first months of life.

Potential application of mesenchymal stromal cells as a new therapeutic approach in acute respiratory distress syndrome and pulmonary fibrosis.

While the COVID-19 outbreak and its complications are still under investigation, post-inflammatory pulmonary fibrosis (PF) has already been described as a long-term sequela of acute respiratory distress syndrome (ARDS) secondary to SARS-CoV2 infection. However, therapeutical strategies for patients with ARDS and PF are still limited and do not significantly extend lifespan. So far, lung transplantation remains the only definitive treatment for end-stage PF.

Left atrium veno-arterial extra corporeal membrane oxygenation as temporary mechanical support for cardiogenic shock: A case report.

Background: Veno-arterial extra corporeal membrane oxygenation (VA-ECMO) support is commonly complicated with left ventricle (LV) distension in patients with cardiogenic shock. We resolved this problem by transeptally converting VA-ECMO to left atrium veno-arterial (LAVA)-ECMO that functioned as a temporary paracorporeal left ventricular assist device to resolve LV distension. In our case LAVA-ECMO was also functioning as a bridge-to-transplant device, a technique that has been scarcely reported in the literature.
