Urban ecosystem services research in Russia: Systematic review on the state of the art.

Research on urban ecosystem services (ES) covers many regions globally, yet significant gaps remain in several areas, including Russia. Furthermore, the number of publications on Russian ES is still very low, and most of them focus on ES assessment on the national level which results in an incomplete understanding of ES provision in Russian cities. To fill this gap, 197 publications on urban ES have been systematically reviewed.

COVID-19 pandemic changes the recreational use of Moscow parks in space and time: Outcomes from crowd-sourcing and machine learning.

The limited access to urban green spaces during the COVID-19 pandemic had a negative impact on the human-nature interaction in cities and human well-being. Number of visitors to green areas, initially declined due to imposed restrictions, was restored after they were lifted as established by several studies across the globe However, little is still known about changes in behavior and preferences of park visitors in the post-COVID time. In this study, we investigated spatial-temporal patterns of recreational activities in the three urban parks in Moscow (Russia) prior, during and after the COVID-19 lockdown (in 2019 and 2020).

[Etiopathogenetic principles fo surgical treatment for purulent wounds].

Application of gas-liquid chromatography methods and mass-spectrometry enabled the authors to develop objective criteria, which provided prompt acceptance of quantity information about the stage ams severity of the wound process, its influence on the organism and prognosis of expectant complications (taking into account aerobic or anaerobic components of microflora) and early correction of surgical policy.

[Reconstructive and restorative operations in surgical treatment of suppurative diseases].

The principles of active surgical treatment of purulent wounds made it possible to perform reconstructive operations on 5,422 patients with large purulent wounds and tissue defects. In 3,887 patients the wounds were closed with sutures and drained, in 1,535 patients the wound surfaces were closed and tissue defects repaired by various methods of cutaneo- and osteoplasty, in 1,261 of these patients free skin graft was carried out. In 274 patients wounds in the region of important anatomical structures and functionally active surfaces were closed by transposed vascularized tissues with good cosmetic and functional results.

[General principles of the treatment of suppurative wounds and suppurative surgical diseases].

The article discusses the results of treatment of 7,092 patients with purulent wounds and septic surgical diseases by means of a suggested method of active surgical management. The main principles of the method are as follows: preoperative examination and preparation of the patients for operation for 12-36 hours; radical excision of all purulent and nonviable tissues followed by active drainage and treatment under conditions of controlled abacterial medium or by ointments on a water-soluble base; use of auxiliary methods for the treatment of the wound surface (pulsed stream of antiseptics, ultrasonic cavitation, vacuum treatment); performance of laboratory tests (microbial dissemination per 1 g tissue, cytologic and morphologic studies, values of tissue hemostasis) as an objective criterion of the course of the wound process and for determining whether the wound surface is ready for closure; accomplishment of intensive therapy; early closure of the wound surface with sutures or by plastic operations. Analysis of the data allows the conclusions that active surgical treatment may be accepted as an optimal and universal method for the management of purulent wounds of any etiology and septic surgical diseases.

[Effect of controlled bacteria-free medium on the course of the wound process in patients with chronic venous insufficiency of the legs complicated by trophic ulcer].

Treatment in a controlled abacterial medium was applied to 102 patients with venous ulcer of the lower limbs. The course of the wound process was studied on the basis of objective examination methods (microbiological, cytological, morphological, study of the activity of tissue hemostasis factors). The results showed that a controlled abacterial medium causes favourable changes in the course of the wound process and allows the trophic ulcer to be prepared for operation in a short period of time (9-12 days).

[Morphology of the suppurative wound in the treatment process in a regulated environment].

Morphological and histochemical studies of biopsies from the areas of purulent wounds in the process of their treatment in a chamber with regulated environment were carried out. After 2-week course of treatment the purulent wound heals like a pure surgical wound. The granulation tissue contains a small number of leukocytes, the vessel is filled with polymorphonuclear leukocytes.
