The impact of the COVID-19 pandemic on burnout levels among healthcare workers: A comparative analysis of the pandemic period and post-pandemic period.

Emotional burnout among physicians is a serious problem that can affect their health and the quality of medical care. This condition occurs when physicians experience excessive stress and pressure at work, often due to high demands and expectations imposed on them by patients. This study aims to assess the experience and factors associated with emotional burnout among health workers who deal with COVID-19-positive patients.

Catalase: A Potential Pharmacologic Target for Hydrogen Peroxide in the Treatment of COVID-19.

Background: Acute respiratory distress syndrome in the elderly with COVID-19 complicated by airway obstruction with sputum and mucus, and cases of asphyxia with blood, serous fluid, pus, or meconium in newborns and people of different ages can sometimes cause hypoxemia and death from hypoxic damage to brain cells, because the medical standard does not include intrapulmonary injections of oxygen-producing solutions. The physical-chemical repurposing of hydrogen peroxide from an antiseptic to an oxygen-producing antihypoxant offers hope for the development of new drugs.

Methods: This manuscript is a meta-analysis performed according to PRISMA guidelines.

Mannitol as a Growth Substrate for Facultative Methylotroph Methylobrevis pamukkalensis PK2.

Biochemistry of carbon assimilation in aerobic methylotrophs growing on reduced C1 compounds has been intensively studied due to the vital role of these microorganisms in nature. The biochemical pathways of carbon assimilation in methylotrophs growing on multi-carbon substrates are insufficiently explored. Here we elucidated the metabolic route of mannitol assimilation in the alphaproteobacterial facultative methylotroph Methylobrevis pamukkalensis PK2.

Dental Tissue Density in Healthy Children Based on Radiological Data: Retrospective Analysis.

Background: Information about the range of Hounsfield values for healthy teeth tissues could become an additional tool in assessing dental health and could be used, among other data, for subsequent machine learning.

Objective: The purpose of our study was to determine dental tissue densities in Hounsfield units (HU).

Methods: The total sample included 36 healthy children (n=21, 58% girls and n=15, 42% boys) aged 10-11 years at the time of the study.

Public perceptions of families affected by pediatric cancer and educational work in pediatric oncology.

Background: This study aims to explore how Russian society perceives children with cancer and their families to determine its potential as a tool for solving the social struggles of cancer-affected youth.

Methods: The study took place between 2019 and 2020 and involved 237 parents of cancer-affected children enrolled for inpatient treatment in 5 pediatric oncology clinics in the North Caucasus Federal District (Russia). The study exploits a specially designed questionnaire survey as its main research method.
