Depressive Symptoms and Amyloid Pathology.
JAMA Psychiatry
January 2025
Department of Psychiatry and Neurochemistry, Institute of Neuroscience and Physiology, Sahlgrenska Academy at the University of Gothenburg, Mölndal, Sweden.
Importance: Depressive symptoms are associated with cognitive decline in older individuals. Uncertainty about underlying mechanisms hampers diagnostic and therapeutic efforts. This large-scale study aimed to elucidate the association between depressive symptoms and amyloid pathology.

Brain tumours are one of the most deadly and noticeable types of cancer, affecting both children and adults. One of the major drawbacks in brain tumour identification is the late diagnosis and high cost of brain tumour-detecting devices. Most existing approaches use ML algorithms to address problems, but they have drawbacks such as low accuracy, high loss, and high computing cost.

Abdom Radiol (NY)
January 2025
Severance Hospital, Seoul, Republic of Korea.
Purpose: To evaluate the performance of R2* in distinguishing intrapancreatic accessory spleens (IPASs) from pancreatic neuroendocrine tumors (PNETs).
Methods: Two radiologists (R1 and R2) retrospectively reviewed the MRIs of 20 IPAS and 20 PNET patients. IPASs were diagnosed with uptake on 99mTc labeled heat-damaged red blood cell scintigraphy or characteristic findings on CT/MRI and ≥ 12 month-long-stability.
Ascending aortic replacement versus aortic root replacement in patients with type A aortic dissection involving the aortic root.
Ther Adv Cardiovasc Dis
January 2025
Department of Cardiac Surgery, LMU University Hospital, Ludwig Maximilian University, Munich, Germany.
Background: Extensive surgical resection of the thoracic aorta in patients with type A aortic dissection (TAAD) is thought to reduce the risk of late aortic wall degeneration and the need for repeat aortic operations.
Objectives: We evaluated the early and late outcomes after aortic root replacement and supracoronary ascending aortic replacement in patients with TAAD involving the aortic root.
Design: Retrospective, multicenter cohort study.
Imaging predictors of adverse prognosis in Fabry disease cardiomyopathy: A systematic review and meta-analysis.
Eur J Clin Invest
January 2025
Department of Clinical Therapeutics, National and Kapodistrian University of Athens, Athens, Greece.
Background: Cardiac involvement represents the main cause of death in patients with Fabry disease (FD). Echocardiography and cardiovascular magnetic resonance (CMR) have an established diagnostic role, but their prognostic value remains unresolved. This systematic review and meta-analysis sought to assess the prognostic implications of imaging parameters in FD.
