Age-Specific Approach to Arterial Stiffness Prediction in Apparently Healthy Patients.

Background: The high prevalence of traditional cardiovascular risk factors among the patients without cardiovascular disease (CVD) allows us to predict an increase in cardiovascular morbidity rate in the future. Arterial stiffness is one of the most important predictors and pathogenetic mechanisms of CVD development. The aim of our study was to evaluate the predictive differences of age-related and age-independent (universal) cardio-ankle vascular index (CAVI) reference values for detecting increased arterial stiffness in individuals without CVD.

The trade-off between COVID-19 and mental diseases burden during a lockdown: Mathematical modeling of control measures.

Background: During the COVID-19 pandemic, many countries used lockdowns as a containment measure. While lockdowns successfully contributed to slowing down the contagion, the related mobility restrictions were reportedly associated with an increased risk of major depressive and anxiety disorders. We aimed to quantify the trade-off between the quality-adjusted life years (QALY) gain due to lower COVID-19 incidence as a result of a lockdown and QALY loss due to lockdown-induced mental disorders.

Effect of Humid Air Exposed to IR Radiation on Enzyme Activity.

Water vapor absorbs well in the infra-red region of the electromagnetic spectrum. Absorption of radiant energy by water or water droplets leads to formation of exclusion zone water that possesses peculiar physico-chemical properties. In the course of this study, normally functioning and damaged alkaline phosphatase, horseradish peroxidase and catalase were treated with humid air irradiated with infrared light with a wavelength in the range of 1270 nm and referred to as coherent humidity (CoHu).

Radiomorphological Manifestations of Femoral and Tibial Cortical Bones at Different Stages of Limb Lengthening.

Background: There has been a lot of research done on Ilizarov's limb lengthening; however, very few publications focus on the quantitative assessment of the distractional bone regeneration in tibial and femur lengthening. Data regarding quality of the bone after lengthening are needed to consider the time of frame removal and develop a rehabilitation program.

Materials And Methods: Computed tomography (CT) assessment of a parent bone was performed on 136 patients with limb length discrepancy and bone deformity of various etiologies before and after lengthening.

Detecting reasons for recurrent deformity in treatment of patients with vitamin D-resistant rickets using diagnostic imaging.

Purpose: To assess age related manifestations of the femur and tibia in patients with vitamin D-resistant rickets (VDR) and explore causes for recurrent deformity using imaging modalities.

Methods: Computed tomography (CT), magnetic resonance imaging (MRI) and dual energy X-ray densitometry (DEXA) were used to assess conditions of long bones of lower limbs in patients with vitamin D-resistant rickets aged from 4 years to 30 years preoperatively and after limb lengthening.

Results: Age related MRI findings showed specific structure of the femur and tibia in patients with VDR preoperatively and after operative treatment.
