Mortality and ocular parameters and diseases.

Background: To assess associations between mortality and major ocular parameters and diseases.

Methods: The population-based Ural Eye and Medical Study (UEMS) and Ural Very Old Study (UVOS) included 5899 individuals (age: 40+ years) and 1526 individuals (age: 85+ years), respectively. Cause-specific mortality was determined using the government regional information and analytical system.

Atrial fibrillation and flutter and ocular diseases. The Ural eye and medical study and the Ural very old study.

Purpose: To assess associations between atrial fibrillation/atrial flutter (AF) and ocular parameters and diseases.

Methods: The population-based Ural Eye and Medical Study (UEMS) and the Ural Very Old Study (UVOS) included 4894 individuals (age: 40+ years) and 835 individuals (age: 85+ years), respectively.

Results: In the UEMS, AF prevalence (80/4894; 1.

Intraocular pressure and its determinants in a very old population. The ural very old study.

Purpose: To explore intraocular pressure (IOP) and its associated parameters in an aged population.

Methods: The epidemiologic Ural Very Old Study (UVOS) conducted in Bashkortostan/Russia included 1526 participants with an age of ≥85 years. Besides a whole series of ocular and systemic examinations, IOP was determined applying non-contact tonometry.

Myopic axial elongation in school children and the COVID-19 lockdown in Russia: The Ural Children Myopia Study.

Background: To explore an influence of the COVID-19-related lockdown on ocular axial elongation in school children in Russia.

Methods: The participants of the school-based Ufa Children Myopia Study in Ufa/Russia underwent, at baseline in 2019/2020 before the COVID-19 outbreak and after a COVID-19-related lockdown, a detailed interview and ophthalmological examination including laser interferometric biometry for axial length measurement.

Results: The study included 461 children (age:10.

Recent Advances in the Chemistry of Saturated Annulated Nitrogen-Containing Polycyclic Compounds.

This review is devoted to the analysis of works published over the past 20 years on the chemistry of saturated annulated nitrogen-containing polycyclic compounds, the molecules of which consist of four, five, six, and seven cycles, and contain from one to eight endocyclic nitrogen atoms.
