The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases.

The epithelial barrier theory proposes that modern environmental exposures compromise skin and mucosal surfaces, initiating local inflammation that propagates systemically. The theory integrates epidemiological trends, molecular mechanistic data, and emerging clinical data to show how everyday exposures cause the development and exacerbation of more than 70 chronic noncommunicable diseases. A canonical epithelial cell and barrier injury cascade takes place, generating oxidative stress with increased reactive oxygen species, the release of alarmins, and multiple chemokines and epithelial barrier disruption.

The Evolution, Immunopathogenesis and Biomarkers of Type 2 Inflammation in Common Allergic Disorders.

The prevalence of allergic diseases, including allergic rhinitis, chronic rhinosinusitis, asthma, eosinophilic esophagitis, food and drug allergies, and atopic dermatitis, has been increasing globally over the past few decades. Allergic diseases are closely linked to type 2 immunity, which is characterized by the coordinated interplay between innate and adaptive immune responses. Significant advancements have been achieved in elucidating the cellular and molecular mechanisms that govern type 2 immunity, chiefly mediated by type 2 cytokines, including IL-4, IL-5, IL-9, and IL-13, which are primarily secreted by T helper 2 cells and group 2 innate lymphoid cells.

Type 2 immunity in allergic diseases.

Significant advancements have been made in understanding the cellular and molecular mechanisms of type 2 immunity in allergic diseases such as asthma, allergic rhinitis, chronic rhinosinusitis, eosinophilic esophagitis (EoE), food and drug allergies, and atopic dermatitis (AD). Type 2 immunity has evolved to protect against parasitic diseases and toxins, plays a role in the expulsion of parasites and larvae from inner tissues to the lumen and outside the body, maintains microbe-rich skin and mucosal epithelial barriers and counterbalances the type 1 immune response and its destructive effects. During the development of a type 2 immune response, an innate immune response initiates starting from epithelial cells and innate lymphoid cells (ILCs), including dendritic cells and macrophages, and translates to adaptive T and B-cell immunity, particularly IgE antibody production.

The epithelial barrier theory and its associated diseases.

The prevalence of many chronic noncommunicable diseases has been steadily rising over the past six decades. During this time, over 350,000 new chemical substances have been introduced to the lives of humans. In recent years, the epithelial barrier theory came to light explaining the growing prevalence and exacerbations of these diseases worldwide.

The markers of the predictive DNA test for canine hip dysplasia may have a stronger relationship with elbow dysplasia.

Canine hip and elbow dysplasias, which are prevalent orthopedic conditions rooted in developmental and hereditary factors are yet to be comprehensively assessed. This study aimed to address this gap by exploring the prognostic significance of five markers linked to canine hip dysplasia using available genome-wide association studies (GWAS) data. The influence of these markers on both hip and elbow dysplasia was examined in dogs exposed to standardized environmental conditions.

Allergen-specific B cell responses in oral immunotherapy-induced desensitization, remission, and natural outgrowth in cow's milk allergy.

Background: Antigen-specific memory B cells play a key role in the induction of desensitization and remission to food allergens in oral immunotherapy and in the development of natural tolerance (NT). Here, we characterized milk allergen Bos d 9-specific B cells in oral allergen-specific immunotherapy (OIT) and in children spontaneously outgrowing cow's milk allergy (CMA) due to NT.

Methods: Samples from children with CMA who received oral OIT (before, during, and after), children who naturally outgrew CMA (NT), and healthy individuals were received from Stanford biobank.

Machine learning algorithm predicts urethral stricture following transurethral prostate resection.

Purpose: To predict the post transurethral prostate resection(TURP) urethral stricture probability by applying different machine learning algorithms using the data obtained from preoperative blood parameters.

Methods: A retrospective analysis of data from patients who underwent bipolar-TURP encompassing patient characteristics, preoperative routine blood test outcomes, and post-surgery uroflowmetry were used to develop and educate machine learning models. Various metrics, such as F1 score, model accuracy, negative predictive value, positive predictive value, sensitivity, specificity, Youden Index, ROC AUC value, and confidence interval for each model, were used to assess the predictive performance of machine learning models for urethral stricture development.

Unveiling the molecular Hallmarks of Peyronie's disease: a comprehensive narrative review.

Peyronie's disease, a fibroinflammatory disorder, detrimentally impacts the sexual well-being of men and their partners. The manifestation of fibrotic plaques within penile tissue, attributed to dysregulated fibrogenesis, is pathognomonic for this condition. The onset of fibrosis hinges on the perturbation of the equilibrium between matrix metalloproteinases (MMPs), crucial enzymes governing the extracellular matrix, and tissue inhibitors of MMPs (TIMPs).

The First Case of Burkholderia cepacia-Induced Myasthenic Crisis.

We report the case of a 62-year-old male patient with a previous diagnosis of myasthenia gravis who experienced a myasthenic crisis due to a lower respiratory tract infection caused by . The patient was admitted to the neuro-intensive care unit and received ventilatory support to address respiratory insufficiency. Treatment included tigecycline and piperacillin-tazobactam for the suspected bacterial infection, as well as targeted management for the myasthenic crisis.

The epithelial barrier: The gateway to allergic, autoimmune, and metabolic diseases and chronic neuropsychiatric conditions.

Since the 1960 s, our health has been compromised by exposure to over 350,000 newly introduced toxic substances, contributing to the current pandemic in allergic, autoimmune and metabolic diseases. The "Epithelial Barrier Theory" postulates that these diseases are exacerbated by persistent periepithelial inflammation (epithelitis) triggered by exposure to a wide range of epithelial barrier-damaging substances as well as genetic susceptibility. The epithelial barrier serves as the body's primary physical, chemical, and immunological barrier against external stimuli.

Household laundry detergents disrupt barrier integrity and induce inflammation in mouse and human skin.

Background: Epithelial barrier impairment is associated with many skin and mucosal inflammatory disorders. Laundry detergents have been demonstrated to affect epithelial barrier function in vitro using air-liquid interface cultures of human epithelial cells.

Methods: Back skin of C57BL/6 mice was treated with two household laundry detergents at several dilutions.

Mechanisms of gut epithelial barrier impairment caused by food emulsifiers polysorbate 20 and polysorbate 80.

Background: The rising prevalence of many chronic diseases related to gut barrier dysfunction coincides with the increased global usage of dietary emulsifiers in recent decades. We therefore investigated the effect of the frequently used food emulsifiers on cytotoxicity, barrier function, transcriptome alterations, and protein expression in gastrointestinal epithelial cells.

Methods: Human intestinal organoids originating from induced pluripotent stem cells, colon organoid organ-on-a-chip, and liquid-liquid interface cells were cultured in the presence of two common emulsifiers: polysorbate 20 (P20) and polysorbate 80 (P80).

Action Myoclonus-Renal Failure Syndrome: A Case Report with Bioinformatic Annotations.

Action myoclonus-renal failure (AMRF) syndrome is a rare autosomal recessive disorder characterized by myoclonic epilepsy with occasional renal failure comorbidity. This study examines a consanguineous family with multiple members presenting myoclonic epilepsy. The disease's continued transmission within the family is attributable to a lack of genetic testing and the inability to establish a definitive diagnosis.
