Bipolar disorder (BD) is a severe mental disorder, characterized by episodes of mania and depression. The longitudinal neurobiological impact of BD episodes on brain structure remains largely unknown. In 124 age-sex-matched participants (62 BD patients; 62 healthy controls; HCs), aged 20-62 years, we investigated the longitudinal relationship between BD episodes and whole-brain gray matter volume (GMV) changes (3 Tesla MRI) during a two-year interval, using voxel-based morphometry in SPM12/CAT12.

The role of residential greenness exposure (RGE) in prevention and control of allergic diseases remains controversial. This systematic review evaluated the association between RGE and the risk of developing asthma, allergic rhinitis (AR), food allergy, atopic dermatitis (AD), and asthma control. MEDLINE and EMBASE searches retrieved 17 cohort and case-control longitudinal studies (12 for asthma, 6 AR, 1 food allergy, 1 ad).

This systematic review evaluated the association between lower respiratory tract infections (LRTI) in infancy with respiratory syncytial virus (RSV), rhinovirus (RV) or infestation with helminths and the risk of developing asthma and allergic diseases. The risk of bias was assessed with ROBINS-E, and the certainty of evidence (CoE) with GRADE. Meta-analysis applied a random-effects model.

Previously, we uncovered the association of increased ERα expression in airway epithelial cells with poor pulmonary function and epithelial-mesenchymal transition (EMT) in asthma patients. This study further investigated the association of ERα expression with the ferroptosis and EMT levels in a cohort of eosinophilic asthma (EA) patients as well as in an eosinophil-epithelial coculture cell model.

Objectives: Asthma is a heterogeneous disease regarding its pathophysiology, clinical symptoms, and response to treatment. Eicosanoids are important inflammatory mediators, able to either promote or attenuate the underlying chronic airway inflammation. We compared eicosanoid expression patterns in the blood circulation and in stimulated blood leukocytes of asthma patients to identify differences in eicosanoid release which may be related to airway inflammation.

The hemolytic, lipemic, and icteric (HIL) indices are critical markers of sample quality, detecting common preanalytical interferences such as hemolysis, lipemia, and icterus. Drone technology offers a novel transport method for medical logistics, particularly in remote or underserved regions.

This study examines the specific role of type-2 immune response in the atopy-PDAC inverse association. To endotype atopic conditions using type-2 immune effectors (i.

These emissions have significant public health implications, contributing to increased morbidity and mortality. Epidemiological and clinical studies have consistently shown that exposure to wildfire smoke exacerbates respiratory conditions such as chronic obstructive pulmonary disease (COPD) and asthma.

Background: Atopic eczema often develops in the first year of life, when the composition of the gut microbiota is most plastic as illustrated by the decrease in bifidobacteria after weaning. This may provide the opportunity for microbial stimuli and their environmental determinants to alter the disease course.
Objectives: To determine the role of the genus Bifidobacterium for atopic eczema in early childhood.

Unlabelled: Non-communicable diseases (NCDs) characterised by type 2 inflammation, including asthma, allergic rhinitis, chronic rhinosinusitis with nasal polyps, atopic dermatitis, food allergies and eosinophilic esophagitis, are increasing in prevalence worldwide. Currently, there is a major paradigm shift in the management of these diseases, towards the concept of disease modification and the treatment goal remission, regardless of severity and age. Remission as a treatment goal in chronic inflammatory NCDs was first introduced in rheumatoid arthritis, and then adopted in other non-type 2 inflammatory diseases.
View Article and Find Full Text PDFImmunoglobulin A (IgA), the most abundantly produced antibody at mucosal surfaces, is thought to play key roles in immune responses to respiratory and enteric pathogens and in the regulation of commensal colonization. Low IgA levels have been associated with recurrent infections and immune dysregulation, including inflammatory bowel disease and autoimmunity. Levels of IgA in maternal breast milk and infant stool are both inversely associated with the emergence of immune responses to food antigens in infants and, in naturally resolving food sensitivity and immunotherapy protocols, the induction of IgA antibodies to dietary antigens has been associated with the acquisition of food tolerance.

Human activities, primarily the burning of fossil fuels, widespread deforestation, soil erosion or machine-intensive farming methods, manufacturing, food processing, mining, construction, and the iron, cement, steel, and chemicals industries, have been the main drivers of the observed increase in Earth's average surface temperature and climate change. Rising global temperatures, extreme weather events, ecosystems disruption, agricultural impacts, water scarcity, problems in access to good quality water, food and housing, and profound environmental disruptions such as biodiversity loss and extreme pollution are expected to steeply increase the prevalence and severity of acute and chronic diseases. Its long-term effects cannot be adequately predicted or mitigated without a comprehensive understanding of the adaptive ecosystems.

Immune activation status determines non-small cell lung cancer (NSCLC) prognosis, with reported positive/negative associations for T helper type 2 (TH2) responses, including allergen-specific IgE and eosinophils. Our study seeks to explore the potential impact of these comorbid immune responses on the survival rates of patients with NSCLC. Our retrospective study used data from the Data Warehouse of the German Center for Lung Research (DZL) and Lung Biobank at Thoraxklinik Heidelberg.

Climate change is not just jeopardizing the health of our planet but is also increasingly affecting our immune health. There is an expanding body of evidence that climate-related exposures such as air pollution, heat, wildfires, extreme weather events, and biodiversity loss significantly disrupt the functioning of the human immune system. These exposures manifest in a broad range of stimuli, including antigens, allergens, heat stress, pollutants, microbiota changes, and other toxic substances.

Inherited alpha-1-antitrypsin deficiency (AATD) is one of the best recognized genetic factors increasing the risk for an early onset COPD with emphysema. The aim of this study was to gain a better understanding of the associations between comorbidities and specific biomarkers in COPD patients with and without AATD to enable future investigations aimed, for example, at identifying risk factors or improving care.

These environmental stressors alter the human exposome and trigger complex immune responses. In parallel, pollutants, allergens, and other environmental factors increase the risks of skin and mucosal barrier disruption and microbial dysbiosis, while a loss of biodiversity and reduced exposure to microbial diversity impairs tolerogenic immune development.
