Clinical Characteristics and Prognosis of Thromboembolism in Elderly Patients With Stage IV Lung Cancer

Geriatrics &Gerontology International, Volume 26, Issue 1, January 2026.
ABSTRACT Background Lung cancer is associated with a high risk of thromboembolism. The incidence and mortality of lung cancer increased in the population over 60 years old. Our research aimed to reveal the risk factors and prognosis of thromboembolism in elderly patients with stage IV lung cancer.

Optimization of Contrast Injection Protocols for Time‐Resolved MRA Technique in Dogs: A Comparative Study of Vascular Signal Characteristics and Artifacts

Veterinary Radiology &Ultrasound, Volume 67, Issue 1, January 2026.
ABSTRACT This study aimed to optimize magnetic resonance angiography (MRA) protocols for time‐resolved MRA imaging in dogs by using different injection rates and contrast volumes. In this experimental and prospective study, four protocols combining two flow rates (0.2 and 2.0 mL/s) and two contrast volumes (0.2 and 0.4 mL/kg, equivalent to 0.1 and 0.2 ...

Syndromic Congenital Heart Disease Diagnosed in Adulthood: A Reminder of the Phenotypic Variability of Alagille Syndrome

Case Reports in Cardiology, Volume 2026, Issue 1, 2026.
Alagille syndrome is a rare multisystemic genetic condition most commonly associated with neonatal liver disease. Variable expressivity is a defining feature of Alagille syndrome, resulting in a broad spectrum of phenotypic variation among individuals who meet the diagnostic criteria. We present an atypical case of cardiac‐predominant Alagille syndrome

Extensive Collateral Venous Circulation and Anatomic Remodeling in Chronic Deep Vein Thrombosis

Case Reports in Cardiology, Volume 2026, Issue 1, 2026.
Chronic deep venous thrombosis (DVT) can result in a significant venous outflow obstruction, often prompting the development of extensive compensatory mechanisms to maintain adequate circulation. We report a case of recurrent DVT, presenting with left lower extremity pain and edema. Venography revealed complete occlusion of the left common femoral vein
