In the early stages of the COVID-19 pandemic, many guidelines for the management of patients with new coronavirus infection did not include recommendations for the use of non-invasive ventilation (NIV) due to the concerns that NIV could be accompanied by high tidal volumes that could cause lung damage. In addition, there was an opinion that NIV increases the risk of spreading bioaerosol containing the SARS-CoV-2 virus. At the same time, NIV was widely used in real clinical practice in the management of severe patients with COVID-19 (in some countries, up to 60% of all respiratory support methods). The accumulated experience demonstrates that when applying NIV, the risk of contamination with viral infections is minimized with adequate use of personal protective equipment. To date, the results of a limited number of studies about effectiveness of NIV in hypoxemic acute respiratory failure (ARF) in patients with COVID-19 are available. In most studies, the need for tracheal intubation and hospital mortality, were on average, 20 β 30%, that suggests a fairly high effectiveness of NIV in ARF in patients with COVID-19.ΠΠ° Π½Π°ΡΠ°Π»ΡΠ½ΡΡ

The inactivation of eggs of helminthes under the action of narrowband ultraviolet radiation of excilamps
The inactivation of eggs of Opisthorchis felineus and Diphyllobothrium latum in the water under the action of UV excilamps at 222 and 282 nm in dependence on the surface dose of radiation was studied. It was observed that the water disinfection from eggs of helminthes was more efficient at 222 nm, than at 282 nm. At the surface dose up to 5 mJ/cm2 of UV radiation at 222 nm up to 85 % of Opisthorchis felineus eggs were inactivated. At the comparable surface dose of UV radiation at 222 nm up to 56 % of Diphyllobothrium latum eggs were inactivated

The use of noninvasive ventilation (NIV) of lungs during the last two decades significantly improved the results of management of severe COPD patients with acute or chronic respiratory failure during both periods of exacerbation and stability. At present, NIV is considered to be the first-line therapy for acute exacerbation of COPD with hypercapnia and respiratory acidosis. This method of airway support turned out to be effective in patients after extubation both for the relief of excommunication from a respirator and for prophylaxis and treatment of postextubation respiratory failure. NIV was proven to be successful in patients with a combination of COPD and obstructive sleep apnea (overlap syndrome), in COPD with pneumonia and in postoperative COPD patients who have undergone lung resectional surgery. The efficacy of NIV under intensive care and intensive therapy unit conditions has stimulated the interest to the use of mask ventilation in hospitals and out-patient departments (for a prolonged domestic therapy). This article presents a review of NIV use in patients with COPD during both periods of exacerbation and stability.Β ΠΠ΅ΠΈΠ½Π²Π°Π·ΠΈΠ²Π½Π°Ρ Π²Π΅Π½ΡΠΈΠ»ΡΡΠΈΡ Π»Π΅Π³ΠΊΠΈΡ

The probability of cultivation of citrus crops on the territory of the Black Sea coast of the Caucasus
According to the result of analysis of 30-year series of agro-climatic data, it shown that south part (Sochi region) of the Black Sea coast of the Caucasus is the most suitable area on the coast for citrus fruits cultivation. Central part of coast has almost optimal agroclimatic indicators and corresponds to all demands and limiting factors of citrus, except for rear short frosts, but without extra loss in crop yields. Northwest part of the Black Sea coast (Anapa region) correspond to the citrus fruits cultivation in terms of heat supply, but inferior in terms of water supply, soils, and criterion of frost susceptibility of the territory. As a result, the cultivation of citrus crops in this area is quite risky, since involves large losses in harvest without appropriate adaptive agrotechnical activities
Neutron scattering studies on ionic diffusion behaviors of superionic -CuSe
We present studies on crystal structure and ionic diffusion behaviors of
superionic CuSe (=0, 0.04, and 0.2) by utilizing neutron
powder diffraction and quasi-elastic neutron scattering. In the superionic
phase, the structural model with Cu ions occupying the Wyckoff sites of 8
and 32 provides the best description of the structure. As the content of Cu
increasing in CuSe, the Cu occupancy increases on the 32 site,
but decreases on the 8 site . Fitting to the quasi-elastic neutron
scattering spectra reveals two diffusion modes, the localized diffusion between
the 8 and 32 sites and the long-range diffusion between the adjacent 8
sites using the 32 site as a bypass, respectively. Between 430 and 650 K, we
measured that the compound with more Cu content exhibits a larger long-range
diffusion coefficient. Temperature in this range does not affect the long-range
diffusion process obviously. Our results suggest the two diffusion modes
cooperative and thus provide a microscopic understanding of the ionic diffusion
of the Cu ions in superionic CuSe.Comment: 6 pages, 3 figure

New equation for determination of overpressure of fuel-air mixture blast
The problems of assessing the consequences of fuel-air mixtures and their prevention are topical and of practical interest. Such the explosions pose a real danger during processing, transportation and storage of fuels at various industrial and civil facilities. Forecast of possible consequences of explosions of fuel-air mixtures is a key element in development of protective measures. Today, various calculation methods have been developed and approved by different departments and organizations. The authors of the article have previously verified methods of Gosatomnadzor (RB G-05-039-96), Rostechnadzor (RD 03-409-01, PB 09-540-03, Method for assessment of consequences of accidental explosions of fuel-air mixtures, General explosion safety rules for explosive chemicals, petrochemicals and refineries), EMERCOM of Russia (GOST R 12.3.047-98, GOST R 12.3.047-2012, SP 12.13130.2009), Netherlands Organisation for Applied Scientific Research, Dorofeev, Baker-Strehlow and Baker-Strehlow-Tang for prediction of consequences of air-fuel mixture explosions at the example of real explosions. It is established that the detonation regime is best described by the Dorofeev's method and multi-energy method of Netherlands Organisation for Applied Scientific Research (ME-TNO) for deflagration regime. Thus, it is promising to create a synthesis method that could combine approaches of the methods. Detonation mode was picked out using the ME-TNO method and replaced by Dorofeev's method. Such a technique allowed proposing a new equation for predicting explosion pressure of fuel-air mixtures. As a result of the research, a new equation is proposed. An equation allows calculating the overpressure of explosion, which more accurately predicts the consequences of fuel-air explosions at petroleum and gas, petrochemical and chemical industries

The aim of this study was to investigate clinical course, survival and predictors of mortality in patients with chronic obstructive pulmonary disease (COPD) with or without pulmonary hypertension (PH). Methods. The study involved 288 patients with COPD (276 males, 12 females; mean age, 59.50 Β± 9.27 years; smoking history, 23.10 Β± 11.42 pack-years; body mass index, 27.20 Β± 12.06 kg Γ m-2; the annual exacerbation rate, 2.40 Β± 0.89), GOLD stage, II β IV (GOLD, 2016). PH was diagnosed if resting systolic pulmonary artery pressure (sysPAP) measured by Doppler echocardiography was > 40 mm Hg. The patients were divided on three groups: those without PH (sysPAP < 40 mm Hg; n = 168), those with moderate PH (sysPAP, 40 β 55 mm Hg; n = 101), and those with severe PH (sysPAP > 55 mm Hg; n = 19). Results. Increased sysPAP was found in 120 patients (41.7%) including 101 patients with moderate PH (35.1%) and 19 patients with severe PH (6.6%). Clinical symptoms of PH were more prominent in COPD patients with severe PH. Clinical symptoms assessed by CAT and Borg's scales, COPD exacerbation rate, the right atrium size, sysPAP, blood levels of C-reactive protein, fibrinogen, NT-proCNP and NT-proBNP predicted mortality of patients with COPD and PH. Survival of COPD patients with PH depended on PH severity. Conclusion. In most patients with COPD and PH, PH was moderate. PH aggravated severity of clinical signs and symptoms and increased the risk of mortality. In-hospital survival of patients with COPD and PH depended on PH severity.Π¦Π΅Π»Ρ.
