Background: Mortality and morbidity of congenital tracheal stenosis (CTS) remain high. The aim of this study was to determine the factors predicting 12-month survival and 2-month successful extubation after tracheoplasty in patients with CTS.
Methods: Retrospective chart reviews were conducted in patients with CTS undergoing tracheoplasty at a single institution between 1997 and 2014. Patients' characteristics at disease onset and tracheoplasty were summarized. Twelve-month survival rate and 2-month extubation rate without tracheotomy after tracheoplasty were analyzed.
Results: We reviewed 81 patients' records. Multivariate analysis for 12-month survival revealed that older age (>2 months, hazard ratio [HR]: 0.08, 95% confidence interval [CI]: 0.02-0.36) or heavier body weight (>4.4 kg, HR: 0.13, 95% CI: 0.02-0.73) at tracheoplasty was a predictive factor for survival. Body weight at tracheoplasty (>8.2 kg, HR: 3.83, 95% CI: 1.88-7.79), preoperative balloon dilatation (HR: 0.30, 95% CI: 0.12-0.78), and carina involvement (HR: 0.36, 95% CI: 0.19-0.69) were predictive factors for successful extubation.
Conclusions: Although CTS management is individualized, age or body weight at tracheoplasty needs to be considered and assessed for survival, as well as preoperative balloon dilatation, and carina involvement for successful extubation.
Levels Of Evidence: Level III.

Background: Over the past five years, the pregnancy rate in assisted reproductive technology (ART) programs in Russia has remained relatively stable. The aim of this study was to assess the distribution of monocyte and macrophage subsets in the blood and follicular fluid of infertile women undergoing assisted reproductive technology.
Methods: The study involved 45 women with a mean age of 35 ± 4.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are emerging as an important class of drugs in the management of Type 2 Diabetes Mellitus (T2DM) and obesity. There are rising concerns of pulmonary aspiration with these medications due to drug-induced gastroparesis. While definitive association is uncertain, it is essential to be prudent and manage these patients as per the current evidence and recommendations.

This study explores the relationship between specific SARS-CoV-2 mutations and obesity, focusing on how these mutations may influence COVID-19 severity and outcomes in high-BMI individuals. We analyzed 205 viral mutations from a cohort of 675 patients, examining the association of mutations with BMI, hospitalization, and mortality rates. Logistic regression models and statistical analyses were applied to assess the impact of significant mutations on clinical outcomes, including inflammatory markers and antibody levels.

Background: Salbutamol, a short-acting β-agonist used in asthma treatment, is available in multiple formulations, including inhalers, nebulizers, oral tablets, and intravenous, intramuscular, and subcutaneous routes. Each formulation exhibits distinct pharmacokinetic (PK) and pharmacodynamic (PD) profiles, influencing therapeutic outcomes and adverse effects. Although asthma management predominantly relies on inhaled salbutamol, understanding how these formulations interact with patient-specific characteristics could improve personalized medicine approaches, potentially uncovering the therapeutic benefits of alternative formulations for an individual patient.
