Difficult airway simulation-based training for anaesthesiologists: efficacy and skills retention within six months.

Background: The aim of this study was to evaluate how anaesthesiologists manage a "cannot intubate, can ventilate" (CI) and "cannot intubate, cannot ventilate" (CICV) scenarios, and how following simulation training will affect their guideline adherence, skills and decision-making immediately after training and 6 months later.

Methods: A prospective controlled study was conducted from July to December 2022. Anaesthesiologists who applied for the continuous medical education course "Difficult Airway Management" were involved in the study.

A comparative study of thermally and chemically treated dairy waste: Impacts on soil phosphorus turnover and availability using 33P isotope dilution.

Dairy processing sludge (DPS) and DPS-derived secondary products such as struvite, biochar, hydrochar and ash (collectively known as SRUBIAS) are emerging as alternatives to fertilizers produced from mined rock phosphate. However, little is known about how these products affect soil P availability and daily P turnover rates..

The incidence and outcomes of healthcare-associated respiratory tract infections in non-ventilated neurocritical care patients: Results of a 10-year cohort study.

The incidence of healthcare-associated respiratory tract infections in non-ventilated patients (NVA-HARTI) in neurosurgical intensive care units (ICUs) is unknown. The impact of NVA-HARTI on patient outcomes and differences between NVA-HARTI and ventilator-associated healthcare-associated respiratory tract infections (VA-HARTI) are poorly understood. Our objectives were to report the incidence, hospital length of stay (LOS), ICU LOS, and mortality in NVA-HARTI patients and compare these characteristics to VA-HARTI in neurocritical care patients.

Influence of sludge layer properties on the hydraulic behaviour of gravel-based vertical flow constructed wetlands for primary treatment of sewage.

Sludge accumulation on the first stage of French design vertical flow constructed wetlands has been reported to improve treatment performance by favouring even sewage distribution on the beds' surface and increasing water retention time. However, due to its relatively low permeability, sludge layer can restrict the hydraulic capacity of the wetlands, requiring careful consideration of the feeding and resting strategy in order to avoid system ponding. This study aimed to elucidate the impact that sludge layer properties have on its permeability and investigate artificial modifications that could enhance it.

Absorption- and Excitation-Modulated Luminescence of Pr, Nd, and Lu Compounds with Dianions of Tetrafluoroterephthalic and Camphoric Acids.

The luminescence of coordination polymers of Pr, Nd, and Lu with tetrafluoroterephthalate and camphorate, [Ln(Fbdc)(DMF)(HO)] (Ln = Pr, Nd, Lu) and [Ln(Camph)(NO)(MeOH)] (Ln = Pr, Nd, Lu), was studied. Ligand-centered and/or metal-centered emissions appear, which depend on the excitation wavelength, ultimately allowing the emitted light color to be adjusted. Low-efficiency ligand-to-metal energy transfer leads to a difference between the excitation spectra of the tetrafluoroterephthalate- and camphorate-Pr compounds, arising from a primary filtering effect on the ligand-centered excitation, by Pr absorption.

Validation of the Russian Version of the Positive and Negative Syndrome Scale (PANSS-Ru) and Normative Data.

: The Positive and Negative Syndrome Scale (PANSS) is widely used to assess psychopathology. The Russian version (PANSSRu) has not been validated, and normative data for the Russian-speaking population currently do not exist. The aims of this study were to 1) complete linguistic validation for the PANSSRu, 2) perform psychometric validation of the Russian translation, and 3) present norms for the Russian and Belarusian population.

Healthcare-associated ventriculitis and meningitis in a neuro-ICU: Incidence and risk factors selected by machine learning approach.

Purpose: To define the incidence of healthcare-associated ventriculitis and meningitis (HAVM) in the neuro-ICU and to identify HAVM risk factors using tree-based machine learning (ML) algorithms.

Methods: An observational cohort study was conducted in Russia from 2010 to 2017, and included high-risk neuro-ICU patients. We utilized relative risk analysis, regressions, and ML to identify factors associated with HAVM development.

Luminescence study of nanosized AlO:Tb obtained by gas-dispersed synthesis.

Terbium-doped AlO samples were obtained by gas-dispersed synthesis. It was shown that the resulting powders, with particle sizes of 10-70 nm, consist of a mixture of transition aluminas, among which the δ -polymorph is dominant. The luminescence properties of AlO:Tb have been studied upon excitation in the UV-visible range of the spectrum.

[Features of prevalence and risk factors of GERD in different age-gender groups].

Aim: To study prevalence and risk factors of gastroesophageal reflux disease in different age-gender groups.

Material And Methods: 506 men of military age, in 375 men in age 40-60 years old, 296 women in age 18-30 years old were investigated. The research included clinical examination with standard questionnaires filling and endoscopy.

Reduction of the transcription level of the mitochondrial genome in human glioblastoma.

Screening of human fetal brain cDNA library by glioblastoma (GB) and normal human brain total cDNA probes revealed 80 differentially hybridized clones. Hybridization of the DNA from selected clones and the same cDNA probes confirmed this difference for 38 clones, of which eight clones contained Alu-repeat inserts with increased levels in GB. Thirty clones contained cDNAs corresponding to mitochondrial genes for ATP synthase subunit 6 (ATP6), cytochrome c oxidase subunit II (COXII), cytochrome c oxidase subunit III (COXIII), NADH dehydrogenase subunit 1 (ND1), NADH dehydrogenase subunit 4 (ND4), and mitochondrial 12S rRNA.

Downregulation of putative tumor suppressor gene TSC-22 in human brain tumors.

Background And Objectives: Our objective was to identify differentially expressed genes involved in the pathogenesis of glioblastoma multiforme (GBM).

Methods: Screening of arrayed human fetal brain and human postnatal brain cDNA libraries was performed by differential hybridization with glioblastoma multiforme and human normal brain cDNAs.

Results: Repeated differential hybridization of more than 100 cDNA clones selected by primary screening and analysis of RNA from adult normal brain and glial tumors showed 16 nucleotide sequences differentially expressed between normal brain and brain tumors.
