Non-invasive detection of cardiac allograft rejection among heart transplant recipients using an electrocardiogram based deep learning model.

Aims: Current non-invasive screening methods for cardiac allograft rejection have shown limited discrimination and are yet to be broadly integrated into heart transplant care. Given electrocardiogram (ECG) changes have been reported with severe cardiac allograft rejection, this study aimed to develop a deep-learning model, a form of artificial intelligence, to detect allograft rejection using the 12-lead ECG (AI-ECG).

Methods And Results: Heart transplant recipients were identified across three Mayo Clinic sites between 1998 and 2021.

Cardiac structure and function in elite female athletes: A systematic review and meta-analysis.

We conducted a meta-analysis to synthesize the best available evidence comparing cardiac biventricular structure and function using cardiac magnetic resonance imaging (CMR) and transthoracic echocardiography (TTE) in elite female athletes and healthy controls (HC). Chronic exposure to exercise may induce cardiac chamber enlargement as a means to augment stroke volume, a condition known as the "athlete's heart." These changes have not been clearly characterized in female athletes.

Acute Unilateral Vision Loss Due to Optic Neuropathy in a Patient with Systemic Lupus Erythematosus.

BACKGROUND Systemic lupus erythematosus (SLE) causes sight-threatening, ophthalmologic problems that are frequently challenging to manage. Optic neuropathy is a rare ophthalmological complication of SLE that can progress to total bilateral vision loss if not identified and treated rapidly. We describe a patient with SLE who presented with an acute, painless unilateral optic neuropathy who subsequently experienced partial recovery of vision when treated with high-dose intravenous corticosteroids.

A 32-year-old man with hypoxemia and bilateral upper-lobe predominant ground-glass infiltrates on chest imaging.

Diffuse alveolar hemorrhage (DAH) is a rare, but potentially fatal, complication of antiphospholipid syndrome, and may present with acute and fulminant symptoms. We report a case of DAH presenting as sudden onset dyspnea in a gentleman with known antiphospholipid syndrome. Chest computed tomography angiography with pulmonary embolism protocol showed right lower lobe segmental filling defects, upper-lobe predominant diffuse ground-glass opacities, and centrilobular nodules bilaterally.

First Reported Case of Respiratory Syncytial Virus Infection Causing Guillain-Barré Syndrome.

Acute immune-mediated polyneuropathies are a group of illnesses that cause paralysis following an infection. We describe a case of one of these illnesses being caused by the respiratory syncytial virus (RSV). An 81-year-old female was admitted for an RSV infection.

Concurrent Spontaneous Pneumomediastinum and Pneumorrhachis.

Background: Spontaneous pneumomediastinum with concurrent pneumorrhachis (air in the spinal canal) and subcutaneous emphysema can be an alarming presentation, both clinically and radiographically. These clinical entities often require only conservative measures after ruling out any worrisome underlying causes. Management often involves appropriate imaging, hospital admission, and sub-specialty consultation as needed to help determine any potential causes for the presentation that may require anything more than a period of medical observation.
