The bidirectional epidemiological association between asthma and obesity is well known. Recent evidence suggests that there is an intersection of the pathophysiological molecular pathways leading to either obesity or asthma, at the level of mitochondria. This is not surprising, because mitochondria, beyond their roles as the metabolic powerhouses of the cell, serve as sensors of threats, regulators of stress signaling, and effectors of cytotoxicity. Reduced mitochondrial function and low metabolic activity are well-recognized features of obesity...

Obesity is one of the major health problems and a determining factor in the prevalence of diseases such as metabolic syndrome, asthma, sleep apnea, infertility and various types of cancer. Its origin is multifactorial, involving genetic, socioeconomic and environmental factors. These last ones contribute mostly to explain the current epidemic growth of this disease. The sedentary lifestyle, inadequate diet, lack of sleep, alterations in intestinal microbiota and stress are factors related to its development...

Movement is the basic attribute of life. It is not surprising that the return to regular physical activity is a very effective and cheap means of preventing and treating most non-cummunicable diseases. Therefore, every physician should be able to prescribe a suitable physical activity. The minimum amount of physical activity with proven effects in primary prevention of chronic diseases is relatively low: 150 minutes of moderate physical activity or 75 minutes of high intensity exercise per week or a combination of the two...

PURPOSE OF REVIEW: Despite currently available treatments, many asthma patients remain inadequately controlled, but identifying distinct patient populations (phenotypes/endotypes) may optimize their management. This review discusses some of the controversies and opportunities for improved disease control in severe asthma. RECENT FINDINGS: Currently approved anti-immunoglobulin E and anti-interleukin 5 biologics, which target specific pathways instead of using a 'one size fits all' strategy, are efficacious and well tolerated therapies for severe asthma...

BACKGROUND: Previous studies have shown that dietary pattern is associated with allergy prevention. METHODS: We conducted a prospective cohort study on all primary schools in Omihachiman City, Shiga Prefecture, Japan. Questionnaires regarding allergic symptoms and diet were distributed to the parents of all 759 7-year-old schoolchildren for 4 consecutive years, from 2011-2014. Specific immunoglobulin E to inhalant allergens were measured at 10 years of age. Participants were then categorized as low, medium, or high intake during the study period for four food groups (fruits, vegetables, fish and beans)...

Acute lung injury (ALI) is a life-threatening syndrome which causes a high mortality rate worldwide. In traditional medicine, lots of aromatic plants-such as some Thymus species-are used for treatment of various lung diseases including pertussis, bronchitis, and asthma. Thymol, one of the primary active constituent derived from Thymus vulgaris (thyme), has been reported to exhibit potent anti-microbial, anti-oxidant, and anti-inflammatory activities in vivo and in vitro. The present study aims to investigate the protective effects of thymol in lipopolysaccharide (LPS)-induced lung injury mice model...

BACKGROUND: A previous aggregate data meta-analysis of randomised controlled trials showed that vitamin D supplementation reduces the rate of asthma exacerbations requiring treatment with systemic corticosteroids. Whether this effect is restricted to patients with low baseline vitamin D status is unknown. METHODS: For this systematic review and one-step and two-step meta-analysis of individual participant data, we searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and Web of Science for double-blind, placebo-controlled, randomised controlled trials of vitamin D3 or vitamin D2 supplementation in people with asthma that reported incidence of asthma exacerbation, published between database inception and Oct 26, 2016...

PURPOSE OF REVIEW: Specific allergen immunotherapy is considered a key candidate for a successful preventive intervention in atopic diseases. The strong association of atopic manifestations such as rhinitis and asthma with atopic sensitizations (specific serum IgE) provide a rationale for early intervention in childhood and adolescence. RECENT FINDINGS: Currently, the documentation of the disease-modifying intervention effects is limited to the secondary prevention of asthma symptoms in children with allergic rhinoconjunctivitis...

BACKGROUND: Sublingual immunotherapy (SLIT) has been successfully employed in IgE-mediated respiratory allergies. However, it is not known whether the modulation of immune responses in the sublingual area during SLIT has any deleterious effect on oral health. We sought to determine the oral health prospectively in children receiving SLIT for house dust mite allergy. MATERIAL AND METHODS: Eighteen children with allergic asthma and/or rhinitis and 31 age-matched healthy controls (HC) were included in an open-labeled trial...

BACKGROUND: Rhinovirus infection triggers acute asthma exacerbations. IL-33 is an instructive cytokine of type 2 inflammation whose expression is associated with viral load during experimental rhinovirus infection of asthmatic patients. OBJECTIVE: We sought to determine whether anti-IL-33 therapy is effective during disease progression, established disease, or viral exacerbation using a preclinical model of chronic asthma and in vitro human primary airway epithelial cells (AECs)...

OBJECTIVES: To assess the oral health status and salivary composition in a group of children suffering from bronchial asthma. MATERIALS AND METHODS: The sample consisted of sixty asthmatic children, sixty healthy negative controls, and sixty healthy positive controls of both sexes with age ranging from 4 to 12 years old. The asthmatics were grouped according to disease severity into mild, moderate, or severe asthmatic. All the children were clinically examined to assess their dental caries experience (decayed, indicated for extraction, and filled primary tooth [def] and decayed-missing-filled permanent tooth [DMF]), dental erosion condition (tooth wear index), and gingival health condition (gingival index [GI])...

Fibroblast to myofibroblast transition (FMT) contributes to bronchial wall remodelling in persistent asthma. Among other numerous factors involved, transforming growth factor type β (TGF-β) plays a pivotal role. Recently it has been demonstrated that connective tissue growth factor (CTGF), a matricellular protein, combines with TGF-β in the pathomechanism of many fibrotic disorders. However, it is not clear whether this interaction takes place in asthma as well. Primary cultures of human bronchial fibroblasts from asthmatic and non-asthmatic subjects were used to investigate the impact of CTGF and TGF-β1 on the fibroblast to myofibroblast transition...

A challenge in the Choosing Wisely campaign is to identify low-value clinical actions supported by high-quality evidence. We applied a method based on crowdsourcing the Daily POEM (patient-oriented evidence that matters) to identify low-value clinical actions from research studies consistent with the principles of Choosing Wisely. In 2016, we analyzed an average of 1,382 questionnaires on 265 unique POEMs delivered to physician members of the Canadian Medical Association. From these questionnaires, we identified the POEMs ranking highest on one questionnaire item directly linked to reducing overdiagnosis or overtreatment...

REVIEW
Paul E Pfeffer, Catherine M Hawrylowicz
There is increasing interest in the therapeutic utility of vitamin D in asthma, which is supported by a significant body of evidence on epidemiologic associations between vitamin D insufficiency and worse asthma control. In support of a causal relationship, vitamin D beneficially modulates diverse immunologic pathways in heterogeneous asthma endotypes, regulating the actions of lymphocytes, mast cells, antigen-presenting cells, and structural cells to dampen excessive inflammatory responses. Allergic asthma is characterized by a failure of immune tolerance and the development of pathologic responses to inhaled aeroallergens, and vitamin D has been extensively shown to support immune regulation...

BACKGROUND: Asthma remains a leading cause of illness, where primary care can assist to reduce hospitalisations through prevention, controlling acute episodes, and overall management of asthma. In Victoria, Asthma hospitalisations were as high as 3.1 hospitalisations per 1000 population in 1993-94. The primary aims of this study are to: determine if changes in asthma hospitalisations have occurred between 2010 and 2015; determine the key factors that impact asthma hospitalisation over time; and verify whether rural and urban asthma hospitalisations are disparate...
