Specific features of growth and development of cultured mucosal cells from the upper respiratory tract were studied during their in vitro stimulation by keratinocyte growth factor (KGF) and epidermal growth factor (EGF). Phenotypic composition and quantitative characteristics of cultured epithelial cells was investigated with the use of monoclonal CD49F antibodies and flow cytofluorometry. The culture technique makes it possible to obtain a large amount of cells for the evaluation of their pathological changes. Moreover, cell cultures can be used to restore lesioned mucosa of the upper respiratory tract both in experiment and under clinical conditions.

The global spread of the novel coronavirus disease 2019, caused by SARS-CoV-2 virus, impacts individuals of all age groups, including lactating women and children. Concerns have been raised regarding the potential transmission of SARS-CoV-2 from mother to child, following the discovery of SARS-CoV-2 RNA in human milk. Therefore, this study aims to investigate whether the Omicron novel coronavirus variants are transmitted through human milk.

Lip ulcers associated with endotracheal tube fixation are a known complication in adults, but their prevalence in neonates and preterm infants remains unclear. We report a case of a right oral commissure ulcer that developed during endotracheal tube fixation at the right oral commissure and left lateral decubitus positioning in an extremely preterm infant with unilateral pulmonary interstitial emphysema (PIE). A male infant was born at 24 weeks and four days of gestation, weighing 696 gm.

Background: Clinical and epidemiological analyses have found an association between coronavirus disease 2019 (COVID-19) and knee osteoarthritis (KOA). Infection with COVID-19 may increase the risk of developing KOA.
Objectives: This study aimed to investigate the potential causal relationship between COVID-19 and KOA using Mendelian randomization (MR) and to explore the underlying mechanisms through a systematic bioinformatics approach.

Objective: To report host-related and environmental factors associated with otitis media (OM), and compare the prevalence of OM in 12-month-old infants reported by parents with that predicted from audiological assessment results.
Design: A non-randomised, cross-sectional design was used. Data were collected via a parental questionnaire during children's audiology appointment at 12 months of age.

Obstructive sleep apnea is a globally prevalent concern with significant health impacts, especially when coupled with comorbidities. Accurate detection and localization of airway obstructions are crucial for effective diagnosis and treatment, which remains a challenge for traditional sleep monitoring methods. Here, we report a catheter-based flexible pressure sensor array that continuously monitors soft tissue pressure in the upper airway and facilitates at the millimeter level.
