Association of dementia and patient outcomes among COVID-19 patients: A multi-center retrospective case-control study.

Background: We conducted a retrospective cohort study on COVID-19 patients with and without dementia by extracting data from the HCA Healthcare Enterprise Data Warehouse between January-September 2020.

Aims: To describe the role of patients' baseline characteristics specifically dementia in determining overall health outcomes in COVID-19 patients.

Methods: We grouped in-patients who had ICD-10 codes for dementia (DM) with age and gender-matched (1:2) patients without dementia (ND).

Thrombocytopenia After Aortic Valve Replacement: Comparison Between Sutureless Perceval S Valve and Perimount Magna Ease Bioprosthesis.

Introduction: The incidence of postoperative thrombocytopenia after aortic valve replacement (AVR) with the Perceval S Sutureless bioprosthesis remains unclear. The aim of this study was to report thrombocytopenia associated with the use of sutureless AVR.

Methods: The data was collected retrospectively for patients who had isolated AVR with sutureless Perceval S valve (Group A: 72 patients) and was compared with patients who underwent isolated sutured AVR with Perimount Magna Ease Bioprosthesis (Group B: 101 patients) in our institution between June 2014 and January 2017.

Aortic Valve Replacement with a Conventional Stented Bioprosthesis versus Sutureless Bioprosthesis: a Study of 763 Patients.

Objective: The aim of this retrospective study was to compare early postoperative outcomes after aortic valve replacement (AVR) with sutureless bioprostheses and conventional stented bioprostheses implanted through median sternotomy.

Methods: From January 2011 to December 2016, 763 patients underwent aortic valve replacement with bioprostheses; of these, 139 received a Perceval S sutureless valve (Group A) and 624 received a Perimount Magna Ease valve (Group B). These groups were further divided into A1 (isolated Perceval AVR), A2 (Perceval AVR with coronary artery bypass grafting [CABG]), B1 (isolated conventional stented bioprosthesis), and B2 (conventional stented bioprosthesis + CABG).

Early Clinical Results of Perceval Sutureless Aortic Valve in 139 Patients: Freeman Experience.

Objective: The aim of this retrospective study is to evaluate the safety and performance of the Perceval sutureless valve in patients undergoing aortic valve replacement. We report the 30-day clinical outcomes of 139 patients.

Methods: From January 2014 to December 2016, 139 patients underwent sutureless aortic valve replacement.

Haemoptysis in an intravenous drug user: injection needle impacted in the left main bronchus.

We report a case of a 35-year-old man who presented with 4-week history of haemoptysis, with a history of intravenous drug use. There was no other significant medical or surgical history and no recollection of any foreign body aspiration. Chest X-ray and CT scan showed 40 mm long needle in left main bronchus, partly lying outside the bronchus into the mediastinum.
