Evgeny I. Kychanov was well known in Chinese academic circles since 1980s, and his translations of the ancient Tangut manuscripts into Russian are often used by Chinese scholars as reference material. This article is based on the example of The Revised and Newly Endorsed Code of the Celestial Prosperity Reign (11491168) translated by the scholar from Tangut into Russian; it analyzes some features of his translation work, his chosen strategies and methods, as well as gives comments of the Chinese specialists attitude to E.I. Kychanovs translation of the Tangut written source.

Background: Hypersensitivity pneumonitis (HP) is an interstitial lung disease (ILD) that occurs in susceptible individuals in response to various inhaled antigens. The fibrotic phenotype of HP is characterized by disease progression and can lead to pulmonary hypertension (PH). The aim of this study was to estimate the prevalence of PH and to identify predictors of PH in patients with chronic HP. Methods: We conducted an observational longitudinal study that included 85 patients with an established diagnosis of HP. Clinical examination, quality of life questionnaires, high-resolution computed tomography (HRCT) of the chest, arterial blood gases analyses, six-minute walking test (6-MWT), pulmonary function tests, and echocardiography were performed. Results: Patients were divided into groups with fibrotic (71.8%) and nonfibrotic phenotype (28.2%). PH was detected in 41 (48.2%) patients. Patients with PH had the predominant fibrotic phenotype of HP, were older, more symptomatic, and had a higher FVC/DLco ratio. The most significant predictors of PH were CT signs of fibrosis, finger clubbing, FVC/DLco, decreased distance, and SpO2 at the end of 6-MWT, as well as the presence of cardiovascular diseases. Conclusions: PH is a common condition in patients with chronic HP, especially with the fibrotic phenotype. Early detection of the PH predictors is necessary for the timely diagnosis of this complication of HP.

Active recruiting is built as a recruitment strategy using computer technology in HR management. The electronic recruiting system improves the quality of interaction between candidates and company managers. Web sites, social networks, and messengers allow building communication with a potential employee on-line. The choice of recruiting methods should be as relevant as possible and formed according to the results of the analysis of the selection funnel. Based on the conversion of the selection stages in the funnel, one can calculate how many candidates are needed to close the vacancy and identify the selection problems. Optimization of the recruitment and selection process using modern methods and tools will allow the company to attract the most qualified and efficient employees. A well-developed staff recruitment system will increase the personnel potential and achieve the strategic goals of the company.

Based on the analysis of the literature, the system of strategic effective management of the company was studied. It is noted that the implementation of the strategic goals by an organization can only be achieved through forming a common goal for all participants and staff involvement. Tools for the formation of employee engagement are proposed. Thanks to SPMS, employees and managers understand mutual expectations, thus reducing the number of conflict situations and ambiguous understanding of everyone's job responsibilities. The decrease in staff turnover, the growth of the customer satisfaction index, and the active participation of employees in a store’s projects make it possible to assess staff involvement. SPMS allows establishing the relationship between the strategic goals of the company with the daily functional responsibilities of staff, involving employees in the phased implementation of the strategy, giving importance to the work of each employee, and determining their contribution to the implementation of strategic goals.

Background: Data on the lung respiratory mechanics and gas exchange in the time course of COVID-19-associated respiratory failure is limited. This study aimed to explore respiratory mechanics and gas exchange, the lung recruitability and risk of overdistension during the time course of mechanical ventilation. Methods: This was a prospective observational study in critically ill mechanically ventilated patients (n=116) with COVID-19 admitted into Intensive Care Units of Sechenov University. The primary endpoints were: «optimum» positive end-expiratory pressure (PEEP) level balanced between the lowest driving pressure and the highest SpO2 and number of patients with recruitable lung on Days 1 and 7 of mechanical ventilation. We measured driving pressure at different levels of PEEP (14, 12, 10 and 8 cmH2O) with preset tidal volume, and with the increase of tidal volume by 100 ml and 200 ml at preset PEEP level, and calculated static respiratory system compliance (CRS), PaO2/FiO2, alveolar dead space and ventilatory ratio on Days 1, 3, 5, 7, 10, 14 and 21.Results: The «optimum» PEEP levels on Day 1 were 11.0 (10.0-12.8) cmH2O and 10.0 (9.0-12.0) cmH2O on Day 7. Positive response to recruitment was observed on Day 1 in 27.6% and on Day 7 in 9.2% of patients. PEEP increase from 10 to 14 cmH2O and VT increase by 100 and 200 ml led to a significant decrease in CRS from Day 1 to Day 14 (p2/FiO2 was 105.5 (76.2-141.7) mmHg in non-survivors on Day 1 and 136.6 (106.7-160.8) in survivors (p=0.002). In survivors, PaO2/FiO2 rose on Day 3 (p=0.008) and then between Days 7 and 10 (p=0.046). Conclusion: Lung recruitability was low in COVID-19 and decreased during the course of the disease, but lung overdistension occurred at «intermediate» PEEP and VT levels. In survivors gas exchange improvements after Day 7 mismatched CRS.Trial registration: ClinicalTrials.gov, NCT04445961.

Background This systematic review and meta-analysis aimed to assess the association between the tricuspid annular plane systolic excursion (TAPSE) measured by echocardiography and mortality in COVID-19. Methods We performed a systematic literature search using PubMed, Embase, and Scopus databases with keywords "COVID-19" OR "SARS-CoV-2" OR “2019-nCoV” AND “Tricuspid annular plane systolic excursion” OR “TAPSE” up until 20 January 2021. The main outcome was mortality; the effect estimate was reported in hazard ratio (HR) which was pooled from the unadjusted and adjusted effect estimate retrieved from the included studies. Mean difference of the TAPSE (in mm) between non-survivors and survivors were pooled. Results There were 641 patients from 7 studies included in this systematic review and meta-analysis. TAPSE was lower in non-survivors compared to survivors (mean difference -3.74 [-5.22, -2.26], p

Highlights • COVID-19 may be characterized by an abnormal coagulation process and microvascular thrombosis of the lung vasculature. • COVID-19 may also be linked with acute respiratory distress syndrome (ARDS) and acute cor pulmonale (ACP). • We confirmed the development of ACP in a patient suffering from COVID-19. • We treated our patient with systemic thrombolysis and this resulted in a marked improvement in hemodynamics. • In addition, there was a significant reduction in hypercapnia, alveolar dead space, and ventilatory ratio., Existing literature highlights the fact that patients with COVID-19 exhibit alterations in the coagulation process and are associated with respiratory and cardiovascular diseases, including acute respiratory distress syndrome and acute cor pulmonale. In this report, we describe the effects of systemic thrombolysis on acute cor pulmonale in a patient suffering from COVID-19. We demonstrated that systemic thrombolysis successfully improved the hemodynamics of our patient and resulted in a prominent reduction in hypercapnia, alveolar dead space, and ventilatory ratio.

Objective: The soluble guanylate cyclase stimulator riociguat is approved for the treatment of adult patients with pulmonary arterial hypertension (PAH) and inoperable or persistent/recurrent chronic thromboembolic pulmonary hypertension (CTEPH) following Phase 3 randomized trials. The EXPosurE Registry RiociguaT in patients with pulmonary hypertension (EXPERT) study was designed to monitor the long-term safety of riociguat in clinical practice. Methods: EXPERT was an international, multicenter, prospective, uncontrolled, non-interventional cohort study of patients treated with riociguat. Patients were followed for at least 1 year and up to 4 years from enrollment or until 30 days after stopping riociguat treatment. Primary safety outcomes were adverse events (AEs) and serious adverse events (SAEs) coded using Medical Dictionary for Regulatory Activities preferred terms and System Organ Classes version 21.0, collected during routine clinic visits and collated via case report forms. Results: In total, 956 patients with CTEPH were included in the analysis. The most common AEs in these patients were peripheral edema/edema (11.7%), dizziness (7.5%), right ventricular (RV)/cardiac failure (7.7%), and pneumonia (5.0%). The most common SAEs were RV/cardiac failure (7.4%), pneumonia (4.1%), dyspnea (3.6%), and syncope (2.5%). Exposure-adjusted rates of hemoptysis/pulmonary hemorrhage and hypotension were low and comparable to those in the long-term extension study of riociguat (Chronic Thromboembolic Pulmonary Hypertension Soluble Guanylate Cyclase–Stimulator Trial [CHEST-2]). Conclusion: Data from EXPERT show that in patients with CTEPH, the safety of riociguat in routine practice was consistent with the known safety profile of the drug, and no new safety concerns were identified. © 2020 The Authors Eli Lilly and Company; Pfizer; Bayer; GlaxoSmithKline; Merck; Actelion Pharmaceuticals; Meso Scale Diagnostics; United Therapeutics Corporation; Novartis Pharma; Merck Sharp and Dohme; GlaxoSmithKline Australia; Deutsche Forschungsgemeinschaft; Grupo Ferrer Internacional, S.A The EXPERT registry was funded by Bayer AG (Berlin, Germany) and Merck Sharp & Dohme Corp., a subsidiary of Merck & Co.

The current socio-economic situation creates similar conditions and rules for companies in various industries around the world.in this vein, the study and educate the retention factors of the company are of a great importance. The task of staff productivity increase and the overall effectiveness of its activities is relevant. The most important role in addressing the issue of employee productivity and performance increasing, as well as his retention is played by employee engagement. The researchers studying engagement at work recognize that this phenomenon is multifaceted and define it as an employee's physical, cognitive and emotional state, causing excessive performance of his functional duties. Involvement is interconnected with the motivational potential of work, therefore, the conditions for the engagement development are the following ones: work significance and diversity, the comparison of work with its result. The authors of the article conducted the study of engagement at work in the enterprises of fishing and fish processing industries. We determined the problems that impede the growth of staff engagement. The authors of the article implemented the program of corrective actions aimed to improve the factors affecting the engagement at work and retention of staff. We determined the interdependence of involvement level and the coefficient of staff turnover, as well as the return of employees to some holding.

Background One of the main pathophysiological mechanisms underlying the severe course of COVID-19 is the hyper-inflammatory syndrome associated with progressive damage of lung tissue and multi-organ dysfunction. IL-17 has been suggested to be involved in hyper-inflammatory syndrome. Objective To evaluate the efficacy and safety of the IL-17 inhibitor netakimab in patients with severe COVID-19. Study design. In our retrospective case-control study we evaluated the efficacy of netakimab in hospitalized patients with severe COVID-19 outside the intensive care unit (ICU). Patients in the experimental group were treated with standard of care therapy and netakimab at a dose of 120 mg subcutaneously. Results 171 patients with severe COVID-19 were enrolled in our study, and 88 of them received netakimab. On the 3 day of therapy, body temperature, SpO2/FiO2, NEWS2 score, and CRP improved significantly in the netakimab group compared to the control group. Other clinical outcomes such as transfer to ICU (11.4% vs 9.6%), need for mechanical ventilation (10.2% vs 9.6%), 28-day mortality (10.2% vs 8.4%), did not differ between the groups. Conclusion In hospitalized patients with severe COVID-19, anti-IL-17 therapy might mitigate the inflammatory response and improve oxygenation, but do not affect the need for mechanical ventilation and mortality.

Background We have investigated the use of nebulized surfactant as a potential therapeutic option for the patients with coronavirus disease 2019 (COVID-19)-associated acute respiratory distress syndrome (ARDS) undergoing non-invasive ventilation. Methods The patients were divided into 2 groups: surfactant (n = 33) and control (n = 32). The subjects in the surfactant group received the inhaled surfactant at daily dose of 150–300 mg. The oxygenation parameters and several clinical outcomes were analyzed. Results On the 5 day of therapy, PaO2/FiO2 improved significantly in the surfactant group compared to the control group (184 (155–212) mmHg vs 150 (91–173) mmHg, p = 0.02). The inhaled surfactant significantly reduced the need for transfer of patients to intensive care units (24.2% vs 46.9%, p = 0.05) and invasive mechanical ventilation (18.2% vs 40.6%, p = 0.04). Even more, the nebulized surfactant shortened the length of non-invasive ventilation (7 (3–13) days vs 11 (5–22) days, p = 0.02) and time spent in hospital (18 (16–27) days vs 26 (21–31) days, p = 0.003) in patients suffering from COVID-19-linked ARDS. Conclusions Our preliminary data provided indications that inhaled surfactant therapy may represent a promising option for patients with COVID-19-associated ARDS. However, larger clinical trials are crucially needed.
