Aims: The aim of this study is to report the development and psychometric properties of the Pulmonary Arterial Hypertension Symptom Scale (PAHSS).
Background: Patients with pulmonary arterial hypertension (PAH) experience multiple symptoms such as dyspnea, fatigue and chest pain, yet there is no comprehensive, validated symptom assessment tool to date.
Methods: This study used a cross sectional design. Participants completed: socio-demographic and medical data form, the PAHSS, the Medical Outcomes Study Short Form-36 and the Profile of Mood States short form.
Results: The PAHSS contains 17 symptoms measured on a 0 to 10 scale. Principal components analysis demonstrated a three factor solution for the PAHSS: pulmonary, diffuse, and cardiac. Coefficient alphas were good. Statistically significant Pearson coefficients were found between the PAHSS and the Medical Outcomes Study Short Form-36 and the Profile of Mood States short form.
Conclusion: Findings show that the PAHSS is a promising scale to assess symptom severity.

Arterial endothelial cells (ECs) reside in a complex biomechanical environment. ECs sense and respond to wall shear stress. Low and oscillatory wall shear stress is characteristic of disturbed flow and commonly found at arterial bifurcations and around atherosclerotic plaques.

This procedure is carried out via a full sternotomy using standard aortic and bicaval cannulations. For the aortic and pulmonary anastomoses, selective antegrade unilateral cerebral perfusion is used after cooling the body temperature to 26 °Celsius. A 12-mm Hancock conduit is interposed between the pulmonary artery and the proximal descending aorta using standard running suture techniques.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging viral hemorrhagic fever with a high fatality rate and notable public health impact, caused by a novel phlebovirus, primarily transmitted through infected tick bites. This study aimed to assess the prevalence of co-infections among hospitalized patients with SFTS, characterize isolated pathogens, and evaluate demographics, clinical features, and laboratory variations to identify potential risk factors for co-infections. In a cohort of 78 SFTS patients categorized into co-infection and non-co-infection groups, 44.
