This study assessed the association of chronic conditions and multimorbidity with perceived stress among community-dwelling adults in 44 low- and middle-income countries. Data were analyzed from the World Health Survey (2002-2004) including 229,293 adults. A perceived stress score [range 0 (lowest stress) -100 (highest stress)] was computed based on two questions from the Perceived Stress Scale. Eleven chronic conditions were assessed. Multivariable linear regression analyses were conducted to explore the associations...

NOTCH is a fundamental signaling system that regulates normal embryonic development and tissue homeostasis in adult life. NOTCH receptor is a single-pass transmembrane protein normally triggered via direct cell-to-cell contact, in which NOTCH ligands bind the extracellular domain of the receptor, inducing γ-secretase cleavage and release of intracellular domain. The intracellular domain binds to the transcriptional effector RBPJκ to activate transcription of target genes that regulate cell differentiation, patterning, and morphogenesis during embryonic development and adult life...

Asthma and COPD are highly prevalent chronic obstructive lung diseases with an associated high burden of disease. Asthma, which is often allergic in origin, frequently begins in infancy or childhood with variable airflow obstruction and intermittent wheezing, cough, and dyspnea. Patients with COPD, in contrast, are usually current or former smokers who present after the age of 40 years with symptoms (often persistent), including dyspnea and a productive cough. Based on age and smoking history, it is often easy to distinguish between asthma and COPD...

Asthma and obstructive sleep apnea syndrome (OSAS) are one of the most common chronic respiratory diseases. These have common risk factors that include obesity, gastroesophageal reflux disease (GERD) and impaired nasal breathing (allergic rhinitis, sinusitis). At the same time, experimental evidence demonstrates common pathophysiological mechanisms of these diseases, such as involvement in the process of the respiratory tract, a systemic inflammatory response, and implementation of neuromechanical reflexes...

Asthma is an airway disease characterised by chronic inflammation with intermittent or permanent symptoms including wheezing, shortness of breath, chest tightness, and cough, which vary in terms of their occurrence, frequency, and intensity. The most common associated feature in the airways of patients with asthma is airway inflammation. In recent decades, efforts have been made to characterise the heterogeneous clinical nature of asthma. The interest in improving the definitions of asthma phenotypes and endotypes is growing, although these classifications do not always correlate with prognosis nor are always appropriate therapeutic approaches...

Taking fish oil supplements in the third trimester of pregnancy was associated with significantly less wheezing or asthma in the child at the age of 3-5 years, according to a randomized clinical trial by Bisgaard et al., NEJM 2017. However, the results of this study should be interpreted with caution. The primary end points were modified at a late stage in the study, and two primary end points, eczema in the first 3 years of life and allergic sensitization at 18 months of age, were demoted to secondary end points, and showed no significant effect of treatment...

OBJECTIVE: Since the Affordable Care Act's implementation, emergency department (ED) visits have increased. Poor asthma control increases the risk of acute exacerbations and preventable ED visits. The Centers for Medicare and Medicaid Services support the reduction of preventable ED visits to reduce healthcare spending. Implementation of interventions to avoid preventable ED visits has become a priority for many healthcare systems yet little data exist examining children's missed asthma management primary care (PC) appointments and subsequent ED visits...

BACKGROUND: In a subset of severe asthma patients, chronic airway inflammation is associated with infiltration of neutrophils, Th-17 cells and elevated expression of Th-17-derived cytokines (e.g., interleukin [IL]-17, IL-21, IL-22). Peripheral neutrophils from allergic asthmatics are known to express higher IL-17 cytokine levels than those from healthy subjects, but the regulatory mechanisms involved are not well understood. We hypothesize that Th-17 regulatory cytokines could modulate IL-17 expression in neutrophils...

BACKGROUND: Living with an allergic disease has consequences for both affected children and their families. The aim of this qualitative study was to gain deeper knowledge of what life is like for families of children with severe allergic disease, in order to improve care and thereby reduce the consequences of living with a chronic disease. METHODS: Four focus group interviews were performed with Swedish parents of children, aged 6-11 and 12-16 years, with severe allergic disease (from one or more allergic conditions, such as food allergy/eczema/hay fever/asthma)...

Asthma is a chronic respiratory disease characterized by reversible airway obstruction with persistent airway inflammation and airway remodeling, which is associated with increased airway smooth muscle (ASM) mass. Licochalcone A is the predominant characteristic chalcone in licorice root. We found that licochalcone A inhibited vascular endothelial growth factor (VEGF)-induced ASM cell proliferation and induced cell cycle arrest. Additionally, VEGF-induced ASM cell proliferation was suppressed via inhibition of extracellular signal-regulated kinase 1/2 (ERK1/2) activity, but not that of Akt...

One of the main challenges in asthma control is adherence to pharmaceutical treatment. The aim of this study was to test the association between adherence to asthma medication, control and medical beliefs, cognitive and emotional perceptions using three different validated questionnaires. Beliefs about asthma medicine, cognitive and emotional factors were determined in a cross-sectional survey of patients attending outpatient pulmonologist practices in Latvia (n = 352). The validated Beliefs about Medicines Questionnaire and the Brief Illness Perception Questionnaire were used...
