Parkinson's Disease: What Can Retinal Imaging Tell Us?

Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor symptoms such as tremors, rigidity, and bradykinesia. While the diagnosis of PD primarily relies on clinical assessments and neurological examination, there has been growing interest in exploring non-invasive imaging techniques to aid in early detection and monitoring of the disease. In recent years, retinal imaging has emerged as a promising tool for studying PD due to the close anatomical and functional similarities between the retina and the brain.

Prognostic value of deep echocardiographic phenotyping in pulmonary arterial hypertension.

Background: A novel approach to derive prognostic information from echocardiography in pulmonary arterial hypertension (PAH) is to define a phenotype of right heart function combining standard echocardiographic parameters which describe right ventricular pump function and systemic venous congestion. We tested the hypothesis that the combination of advanced strain imaging parameters could yield high prognostic accuracy.

Methods: This was a prospective observational study with a single centre derivation cohort and a second centre validation cohort.

[Short dual antiplatelet therapy: how, when and why].

Dual antiplatelet therapy (DAPT) is a cornerstone of antithrombotic treatment in patients undergoing percutaneous coronary intervention. The optimal duration of DAPT, i.e.
