Improving organ dose sparing in left‐sided breast cancer with yaw‐limited volumetric modulated arc therapy: A dosimetric comparison to conventional and intensity modulated radiation therapy approaches

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background To assess the dose‐sparing capabilities of a yaw‐limited volumetric modulated arc therapy (YL_VMAT) beam setup for adjacent organs at risk (OAR) in comparison with 3D‐conventional radiation therapy (3D‐CRT), intensity‐modulated radiation therapy (IMRT) and conventional VMAT for radiation therapy in left‐sided breast cancer patients.

Structural and hemodynamic properties in murine pulmonary arterial networks under hypoxia-induced pulmonary hypertension [PDF]

arXiv, 2020
Detection and monitoring of patients with pulmonary hypertension, defined as mean blood pressure in the main pulmonary artery above 25 mmHg, requires a combination of imaging and hemodynamic measurements. This study demonstrates how to combine imaging data from microcomputed tomography (micro-CT) images with hemodynamic pressure and flow waveforms from

If it does not help, it might hurt: Pharmacodynamics of a second IVIg course in Guillain–Barré syndrome

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Objectives Intravenous immunoglobulin (IVIg) is an effective treatment for Guillain–Barré syndrome (GBS), but recovery varies between patients. This study aims to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of a single and a second IVIg dose (SID) in patients with GBS.

Rapamycin reverses pulmonary artery smooth muscle cell proliferation in pulmonary hypertension.

American Journal of Respiratory Cell and Molecular Biology, 2013
Pulmonary artery (PA) smooth muscle cell (SMC) proliferation in pulmonary hypertension (PH) may be linked to dysregulated mammalian target of rapamycin (mTOR) signaling.

Incidence of and Risk of Mortality After Hip Fractures in Rheumatoid Arthritis Relative to the General Population

Arthritis Care &Research, EarlyView.
Objective Osteoporosis, a known complication of rheumatoid arthritis (RA), increases the risk of hip fracture, which is associated with high morbidity and mortality. Fracture risk estimates in patients with RA treated with contemporary treatment strategies are lacking.

Delayed diagnosis of pulmonary artery thrombosis in a patient undergoing mitral valve replacement

Annals of Cardiac Anaesthesia
The occurrence of pulmonary artery thrombus in association with rheumatic mitral stenosis is a rare complication. Pulmonary artery thrombus formation may worsen pulmonary artery pressures, and this may precipitate acute right heart failure.

Prognostic relevance of a non‐invasive evaluation of right ventricular function and pulmonary artery pressure in patients with chronic heart failure

European Journal of Heart Failure, 2013
To determine the prognostic relevance of the echocardiographic evaluation of pulmonary artery systolic pressure (PASP) and tricuspid annular plane systolic excursion (TAPSE) in patients with chronic heart failure (CHF).

Application and reduction of a nonlinear hyperelastic wall model capturing ex vivo relationships between fluid pressure, area and wall thickness in normal and hypertensive murine left pulmonary arteries [PDF]

arXiv, 2022
Pulmonary hypertension is a cardiovascular disorder manifested by elevated arterial blood pressure together with vessel wall stiffening and thickening due to alterations in collagen, elastin and smooth muscle cells. Hypoxia-induced (type 3) pulmonary hypertension can be studied in animals exposed to a low oxygen environment for prolonged time periods ...

Immunosuppressive Drugs in Early Systemic Sclerosis and Prevention of Damage Accrual

Arthritis Care &Research, EarlyView.
Objective Organ damage in patients with systemic sclerosis (SSc) in individual organs such as the lungs may be prevented by receiving immunosuppressive drugs (ISs). A new measure of global organ damage, the Scleroderma Clinical Trials Consortium Damage Index (SCTC‐DI), has allowed us to investigate whether receiving ISs may reduce global organ damage ...
