[Visual deficit as a marker of cognitive impairment.].

Glaucoma and cataract continue to be the leading causes of visual deficits, especially in older age groups, but the association of visual deficits with cognitive impairments has not been sufficiently studied. The aim of this study is to study visual impairment as a marker of cognitive impairment in patients with cataracts and glaucoma. The study included 326 elderly patients with cataracts and 318 elderly patients with primary open-angle glaucoma.

[Nanotechnologies in ophthalmology].

Application of new materials and methods in the diagnosis and treatment of eye diseases is one of the promising research areas in modern ophthalmology. Significant progress has been made in understanding the pathogenesis, diagnosis and treatment of eye diseases using nanotechnologies and nanomaterials. This paper presents the main achievements and results of original research on this issue.

[The effect of sarcopenic obesity and age-associated ophthalmopathology on patients' daily activities.].

Along with an increase in the number of elderly and senile populations, there will simultaneously be an increase in the prevalence of age-associated ophthalmopathology and sarcopenic obesity, which can potentially contribute to a decrease in patients' activities in everyday life, but the latter remains practically unexplored, and if analyzed, then without the use of special scales for patients with visual organ pathology or quality of life indicators. The aim of the study was to study the effect of sarcopenic obesity and age-associated ophthalmopathology on the activities of patients in everyday life. 125 mature and elderly patients suffering from sarcopenic obesity combined with cataract and 138 patients of similar age with sarcopenic obesity combined with glaucoma were examined.

[Effect of combined diabetic retinopathy and cataract on instrumental functional activity of patients.].

A potential factor that significantly reduces the social activity of older people is visual impairment due to age-associated eye diseases - cataracts and diabetic retinopathy, which dominate in this age cohort. The aim of the study was to study the social activity of elderly patients with diabetic retinopathy and cataracts. According to a special questionnaire, 115 people 60-74 years old with combined cataract and diabetic retinopathy and 102 people 60-74 years old without ophthalmological diseases were questioned based on the Tambov branch of the MNTK «Academician S.

[Prognostic value of matrix metalloproteinases in the development of diabetic retinopathy in the elderly].

The development of diabetic retinopathy is associated with matrix metalloproteinases, but they are rarely used to predict this pathology. The aim of the study was to predict the development of non-proliferative diabetic retinopathy in old age by the level of matrix metalloproteinases in blood plasma. The main study group consisted of 63 patients aged 60-74 years with type 2 diabetes mellitus and non-proliferative diabetic retinopathy, the control was 56 patients of the same age with type 2 diabetes mellitus and the absence of diabetic retinopathy and other ophthalmopathology at present and in the anamnesis.

"Flora of Russia" on iNaturalist: a dataset.

Background: The "Flora of Russia" project on iNaturalist brought together professional scientists and amateur naturalists from all over the country. Over 10,000 people were involved in the data collection.

New Information: Within 20 months, the participants accumulated 750,143 photo observations of 6,857 species of the Russian flora.

Experimental evidence for short-pulse laser heating of solid-density target to high bulk temperatures.

Heating efficiently solid-density, or even compressed, matter has been a long-sought goal in order to allow investigation of the properties of such state of matter of interest for various domains, e.g. astrophysics.

[TRANSCUTANEOUS PUNCTURE DRAINING OF THE LIQUID ACCUMULATIONS IN RETROPERITONEAL CELLULAR TISSUE IN PURULENT—SEPTIC COMPLICATIONS OF AN ACUTE PANCREATITIS].

The results of miniinvasive transcutaneous interventions for purulent—septic complications of pancreonecrosis are presented. The computeric tomography (CT) and the ultrasound investigation data where compared while choosing of transcutaneous access towards purulent focus. Peculiar attention was drawn to searching of extraperitoneal trajectory for the drain conduction way.

[THE RISK OF OCCURRENCE OF THE VARICOSE DISEASE RECURRENCE, DEPENDING ON DIAMETER OF VARICOSE--CHANGED VEINS OF LOWER EXTREMITIES WHILE PERFORMANCE OF THE FOAM SCLEROTHERAPY].

The results of treatment of 139 patients, to whom for the varicose disease of lower extremities there was conducted a foam sclerotherapy of trunks and tributaries of big subcutaneous vein, small subcutaneous vein and/or nonsaphenous veins with signs of a valvular insufficiency under ultrasonographic control were presented. Complex of measures for prophylaxis of the disease recurrences and complications was elaborated.

[A MIDDLE-TERM RESULTS OF ENDOVENOUS LASER ABLATION FOR VARICOSE DISEASE OF THE LOWER EXTREMITIES].

Abstract The results of endovascular laser ablation (EVLA) under ultrasonographic control in treatment of the lower extremities varicose disease (LEVD) in 189 patients (214 extremities) were analyzed. There was established, that for the trustworthy information obtaining the ultrasonographic duplex angioscanning conduction is necessary. The fibrous involution of a big subcutaneous vein trunk was achieved in (97.

[Tactics in the treatment of postoperative intestinal fistula].

The experience with treatment of 331 patient with external intestinal fistulas is summarized. It is necessary to remove the high non-shaped "emaciating" fistulas at day 1-2 after their development. A rational method for the treatment of other non-shaped intestinal fistulas is their open management with active aspiration, or flowing drainage.
