Clinical Implications of Single Nucleotide Polymorphisms in Diagnosis of Asthma and its Subtypes.

Yonsei Med J 2019 Jan;60(1):1-9

Department of Interdisciplinary Program in Biomedical Science, Graduate School, Soonchunhyang University, Bucheon, Korea.

For the past three decades, a large number of genetic studies have been performed to examine genetic variants associated with asthma and its subtypes in hopes of gaining better understanding of the mechanisms underlying disease pathology and to identify genetic biomarkers predictive of disease outcomes. Various methods have been used to achieve these objectives, including linkage analysis, candidate gene polymorphism analysis, and genome-wide association studies (GWAS); however, the degree to which genetic variants contribute to asthma pathogenesis has proven to be much less significant than originally expected. Subsequent application of GWAS to well-defined phenotypes, such as occupational asthma and non-steroidal anti-inflammatory drugexacerbated respiratory diseases, has overcome some of these limitations, although with only partial success.

Innate T cells in the intensive care unit.

Mol Immunol 2018 Dec 13;105:213-223. Epub 2018 Dec 13.

Brigham and Women's Hospital, Pulmonary and Critical Care Medicine, Boston, MA, 02115, United States; Harvard Medical School, Boston, MA, 02115, United States.

Rapid onset of acute inflammation is a hallmark of critical illnesses that bring patients to the intensive care unit (ICU). In critical illness, innate T cells rapidly reach full activation and drive a robust acute inflammatory response. As "cellular adjuvants," innate T cells worsen inflammation and mortality in several common critical illnesses including sepsis, ischemia-reperfusion injury, stroke, and exacerbations of respiratory disease.

Increasing complexity and interactions of oxidative stress in chronic respiratory diseases: An emerging need for novel drug delivery systems.

Chem Biol Interact 2018 Dec 13. Epub 2018 Dec 13.

Priority Research Centre for Healthy Lungs, Hunter Medical Research Institute (HMRI) & School of Biomedical Sciences and Pharmacy, University of Newcastle, Callaghan, NSW, 2308, Australia; Faculty of Science, University of Technology Sydney, Ultimo, NSW, 2007, Australia; Centre for Inflammation, Centenary Institute, Sydney, NSW, 2050, Australia.

Oxidative stress is intensely involved in enhancing the severity of various chronic respiratory diseases (CRDs) including asthma, chronic obstructive pulmonary disease (COPD), infections and lung cancer. Even though there are various existing anti-inflammatory therapies, which are not enough to control the inflammation caused due to various contributing factors such as anti-inflammatory genes and antioxidant enzymes. This leads to an urgent need of novel drug delivery systems to combat the oxidative stress. Read More

Effects of co-exposure of lipopolysaccharide and β-glucan (Zymosan A) in exacerbating murine allergic asthma associated with Asian sand dust.

Environmental Chemistry Division, National Institute for Environmental Studies, Ibaraki, 305-8506, Japan.

During the 2000s, Asian sand dust (ASD) was implicated in the increasing prevalence of respiratory disorders, including asthma. We previously demonstrated that a fungus from ASD aerosol exacerbated ovalbumin (OVA)-induced airways inflammation. Exposure to heat-inactivated ASD (H-ASD) and either Zymosan A (ZymA, containing β-glucan) or lipopolysaccharide (LPS) exacerbated allergic airways inflammation in a mouse model, but the effects of co-exposure of LPS and β-glucan are unclear.

Obesity and inflammation.

Eur Cytokine Netw 2018 Sep;29(3):83-94

Department of Gastroenterology, Human Nutrition and Internal Medicine, Poznan University of Medical Sciences, Fredry 10, Poznan 61-701, Poland.

The prevalence of obesity has recently increased dramatically and has contributed to the increasing prevalence of various pathological conditions, including type 2 diabetes mellitus, nonalcoholic fatty liver disease, asthma, various types of cancer, cardiovascular and neurodegenerative diseases, and others. Accumulating evidence points to localized inflammation in adipose tissue, which, in turn, promotes systemic low-grade inflammation as a primary force contributing to the development of these pathologies. A better understanding of the underlying mechanisms behind obesity-induced adipose tissue inflammation is required to develop effective therapeutic or prophylactic strategies. Read More

Methods for Assessing Mast Cell Responses to Engineered Nanomaterial Exposure.

Methods Mol Biol 2019 ;1894:31-45

Department of Pharmaceutical Sciences, Colorado Center for Nanomedicine and Nanosafety, Skaggs School of Pharmacy and Pharmaceutical Sciences, University of Colorado, Aurora, CO, USA.

Mast cells are key effector cells in inflammatory and allergic immune responses such as asthma, rhinitis, and atopic dermatitis. Activation of mast cells leads to immediate release of preformed mediators such as histamine and proteases, which can regulate vascular permeability and the function of a number of immune and nonimmune cells. Engineered nanomaterials (ENM) have been utilized for a wide range of applications and introduced into a number of consumer products; yet the consequent increase in human exposure and any potential adverse effects have not been fully evaluated.

Uneven distribution of ventilation, or ventilation heterogeneity, has been observed in asthma for over 60 years using multiple breath nitrogen washout (MBNW) studies. Ventilation heterogeneity has been known to predict airway hyperresponsiveness (the ability of the airways to constrict too easily and by too much) in asthma, which is a core physiological characteristic of this disease. SPECT ventilation imaging allows topographical analysis of changes in ventilation distribution. Read More

Proposal for a screening questionnaire for detecting habitual mouth breathing, based on a mouth-breathing habit score.

BMC Oral Health 2018 Dec 13;18(1):216. Epub 2018 Dec 13.

Department of Oral Biomedical Research, Total Health Advisers Co., Chiba-shi, Chiba, Japan.

Background: When mouth breathing becomes habitual, it can cause sleep disorders and abnormal maxillofacial growth, thus early detection of habitual mouth breathing is important. We created a questionnaire for early detection of habitual mouth breathing using a score based on a spectrum of factors found to be characteristic of mouth breathers.

Methods: First, a draft 50-question questionnaire was given to 101 random dental clinic patients, classified by dental professionals into habitual mouth breathers (n = 28) and nose breathers (n = 73). Read More

Asthma is an inflammatory disease caused by an imbalance of Th1 and Th2 cells. In general, asthma is characterized by a stronger Th2 response. Most conventional asthma treatment focuses on improving airway flow or suppression of airway inflammation. Read More

Tarsal Tunnel Mechanosensitivity Is Increased in Patients with Asthma: A Case-Control Study.

J Clin Med 2018 Dec 12;7(12). Epub 2018 Dec 12.

Department of Nursing, University Center of Plasencia, University of Extremadura, 10600 Plasencia, Spain.

Based on changes in lung function and musculoskeletal disorders in patients with asthma, this study aimed to compare the tarsal tunnel and fibular bone pressure pain thresholds (PPTs) of patients with asthma and healthy matched-paired controls. A case-control study was performed. One hundred participants were recruited: 50 asthma patients and 50 healthy matched-paired controls. Read More
