Article Abstract
Objective: Interaction of genotype and environment results in a specific phenotype of the clinical course of asthma. TGFβ-1 gene belongs to the important group of genes involved in the regulation of proliferation, differentiation, adhesion, and migration of a variety of cell types. TGFβ-1 is inhibitory for B and T cells, as well as IgE production. In particular, it is engaged in inflammation of the bronchi and airway remodeling in asthma, which processes are critical in the pathogenesis of the disease. The aim of this study was to evaluate the correlation between the level of expression of TGFβ-1 and the severity of asthma.
Methods: The study included 39 participants (20 healthy subjects and 19 patients with asthma). Each sample was analysed by using real time PCR.
Results: There was statistical associations between the control group and the group of patients (p = 0,00007). It was demonstrated strong correlation between healthy and patients with severe asthma according GINA guidelines (p = 0,017). It was found the strong statistical correlation between healthy and patients with severe corticosteroid dependent asthma (p = 0,013). Correlations were observed between levels of asthma severity according to the ATS guidelines and controls. The influence of the level of TGFβ-1 mRNA expression and the severity of asthma (ATS) in the FEV1 (%) parameter value was found.
Conclusion: It was found that an important role is played by TGFβ-1 in the pathogenesis of asthma.

Many trials are designed to collect outcomes at or around pre-specified times after randomization. If there is variability in the times when participants are actually assessed, this can pose a challenge to learning the effect of treatment, since not all participants have outcome assessments at the times of interest. Furthermore, observed outcome values may not be representative of all participants' outcomes at a given time.

Background The demand for cosmetic procedures has increased significantly due to their positive effects on self-satisfaction. However, individuals often underestimate the potential complications associated with these procedures, driven by a strong desire for transformation. Therefore, this study aimed to evaluate the Madinah community's awareness of cosmetic procedures and plastic surgery, as well as to assess the risks, complications, and clinical outcomes associated with these procedures.

Previous observational studies focused on the association of tea intake and allergic diseases. However, it is not known whether these associations are causal. We used a bidirectional Mendelian randomization (MR) study to assess the causal relationship of tea intake with the risk of allergic diseases, such as atopic dermatitis (AD), allergic rhinitis (AR), and allergic asthma (AA).

Background: The red cell distribution width to albumin ratio (RAR), a newly identified biomarker of inflammation, has been linked to a variety of inflammatory diseases. Asthma, a major burden on global health, is an inflammatory airway disease that is profoundly affected by inflammation. This study primarily sought to examine the influence of RAR on the risk of developing asthma.

Background: Nonsteroidal anti-inflammatory drugs-exacerbated respiratory disease (NSAIDs-ERD) is characterized by altered arachidonic acid (AA) metabolism. Aspirin hypersensitivity is diagnosed using aspirin challenge, while induced sputum is collected to perform cell counts and to identify local biomarkers in induced sputum supernatant (ISS). This study aimed to assess the levels of a newly identified eicosanoid, 15-oxo-eicosatetraenoic acid (15-oxo-ETE), in ISS at baseline and during aspirin-induced bronchospasm in patients with NSAIDs-ERD.
