AI Article Synopsis
- The study examines how smoking affects the function of the left and right ventricles of the heart using Doppler imaging techniques in 20 healthy individuals.
- Significant changes in diastolic function parameters, such as mitral and tricuspid inflow velocities, were observed 30 minutes after smoking a cigarette.
- Results indicate that acute smoking has a negative impact on both the left and right ventricular function, emphasizing the immediate cardiovascular risks associated with smoking even in healthy nonsmokers.
Article Abstract
Acute effects of smoking on left and right ventricular function is determined by conventional and tissue Doppler imaging methods in this study. Pulsed-wave Doppler indices of the left and right ventricle diastolic function, including mitral and tricuspid inflow peak early and late velocity and their ratio were obtained from 20 healthy subjects by conventional Doppler and tissue Doppler imaging. Echocardiographic indices of left and right ventricles, including isovolumetric relaxation time, deceleration time, isovolumetric contraction time, ejection time, and myocardial performance index of right ventricle were measured before and 30 minutes after smoking a cigarette. Mitral and tricuspid inflow parameters and right ventricular myocardial performance index significantly altered after smoking a cigarette. Among the tissue Doppler imaging parameters, mitral and tricuspid lateral annulus diastolic, but not systolic, velocities altered after smoking a cigarette. Acute cigarette smoking alters left and right ventricular diastolic functions in healthy nonsmokers.

Combination immune checkpoint inhibitors (nivolumab and ipilimumab) are currently a first-line treatment for mesothelioma; however, not all patients respond. The efficacy of treatment is influenced by the tumor microenvironment. Murine mesothelioma tumors were irritated with various radiotherapy doses.

Background: Inflammation is increasingly recognised as a treatment target in hand osteoarthritis, and therefore correct measurement of local inflammation is essential. This study aimed to assess ultrasound scoring of synovitis and the additional value of the Global OMERACT/EULAR Ultrasound Synovitis Score (GLOESS) in hand osteoarthritis.
Methods: Data from the randomised, double-blinded Hand Osteoarthritis Prednisolone Efficacy (HOPE) trial were used.

Background/aim: Tumors exhibit impaired blood flow and hypoxic areas, which can reduce the effectiveness of treatments. Characterizing these tumor features can inform treatment decisions, including the use of vasculature modulation therapies. Imaging provides insight into these characteristics, with techniques varying between clinical and preclinical settings.

Cardiovascular (CV) diseases caused 20.5 million deaths in 2021, making up nearly one-third of global mortality. This highlights the need for practical prognostic markers to better classify patients and guide treatment, especially in ischemic heart disease (IHD), which represents one of the leading causes of CV mortality.

The effect of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) on left ventricular dyssynchrony was unclear. Patients with one CTO vessel were included. Tissue Doppler imaging (TDI) was used to assess the left ventricular dyssynchrony index (DI) in twelve segments before and after successful CTO PCI.
