Premium Monovision versus Bilateral Myopic Monovision, Hybrid Monovision and Bilateral Trifocal Implantation: A Comparative Study.

Purpose: Contemporary monovision techniques use premium intraocular lenses (IOLs), either in both eyes or at least in the non-dominant one. Primary objective of this study was to compare the efficacy of premium monovision (implantation of the trifocal diffractive Panoptix IOL in the non-dominant eye and the bifocal hybrid refractive-diffractive Restor IOL in the dominant eye), against bilateral myopic monovision (implantation of the monofocal SN60WF IOL targeting -0.50 D in the dominant eye and -1.

Determinants of compliance to the facemask directive in Greece: A population study.

Purpose: Primary objective of this study was to identify potential difficulties and/or discomfort when using a facemask. Moreover, to explore the impact of spectacles, contact lenses and visual acuity on the compliance to the facemask directive.

Methods: This is a prospective study that was conducted at the Department of Ophthalmology, University Hospital of Alexandroupolis, Greece between June 2020 and August 2020.

Assessment of cardiac function with Doppler tissue imaging in asymptomatic HIV-infected patients.

Doppler tissue imaging (DTI) is a useful tool for the detection of subtle systolic function abnormalities related to the longitudinal contraction. We assessed left ventricular (LV) systolic function with DTI in 45 human immunodeficiency virus (HIV)-infected patients without any heart-related symptoms and in 30 healthy control subjects. Although conventional echocardiography showed no differences between groups, DTI revealed lower peak systolic velocities in group A patients when compared with group B ones (Sms: 8.

Functional electrical stimulation improves endothelial function and reduces peripheral immune responses in patients with chronic heart failure.

Background: Previous studies have shown beneficial effects of functional electrical stimulation (FES) on muscle performance and exercise capacity of patients with chronic heart failure. This study evaluates the impact of FES on endothelial function and peripheral markers of immune activation in patients with moderate to severe heart failure.

Methods: Twenty-four patients with a left ventricular ejection fraction of less than 40% and New York Heart Association class II-III symptoms, undergoing optimized drug therapy, were randomly assigned (2 : 1) to a 6-week training programme of FES (n=16) or served as controls (n=8).

Tissue Doppler echocardiography reveals insufficient contractile reserve recruitment during effort in subjects with mitral valve prolapse and those with thick mitral valve.

Objective: To assess by tissue Doppler echocardiography (TDE), the tissue velocities, both at rest and after exercise stress testing, in subjects with mitral valve prolapse (MVP) and those with thick mitral valve (TMV).

Methods: Twenty individuals with typical MVP, 30 with TMV, and 30 healthy controls were enrolled. TDE was performed at the basal-inferior wall and the parameters evaluated were the S, Em, and Am velocities, as well as the Em/Am ratio.
