Abstract
The incidence of obesity and asthma continues to enhance, significantly impacting global public health. Adipose tissue is an organ that secretes hormones and cytokines, causes meta-inflammation, and contributes to the intensification of bronchial hyperreactivity, oxidative stress, and consequently affects the different phenotypes of asthma in obese people. As body weight increases, the risk of severe asthma increases, as well as more frequent exacerbations requiring the use of glucocorticoids and hospitalization, which consequently leads to a deterioration of the quality of life. This review discusses the relationship between obesity and severe asthma, the underlying molecular mechanisms, changes in respiratory function tests in obese people, its impact on the occurrence of comorbidities, and consequently, a different response to conventional asthma treatment. The article also reviews research on possible future therapies for severe asthma. The manuscript is a narrative review of clinical trials in severe asthma and comorbid obesity. The articles were found in the PubMed database using the keywords asthma and obesity. Studies on severe asthma were then selected for inclusion in the article. The sections: 'The classification connected with asthma and obesity', 'Obesity-related changes in pulmonary functional tests', and 'Obesity and inflammation', include studies on subjects without asthma or non-severe asthma, which, according to the authors, familiarize the reader with the pathophysiology of obesity-related asthma.

Abstract
Asthma is the most common chronic medical condition in pregnancy. Asthma exacerbations in pregnancy are unpredictable, and are associated with adverse maternal and fetal perinatal outcomes such as preterm birth and low birthweight. Goals of asthma management in pregnancy are to establish effective asthma control and prevent exacerbations. Optimising the management of asthma in pregnancy is an important goal of practice and future research.Treatable traits is a precision medicine paradigm proposed for the management of airways diseases, which holistically addresses the complexity and heterogeneity of airways disease. It is an individualised treatment approach that aims to improve outcomes. This makes treatable traits well suited for pregnant women with asthma, who have a high prevalence of obesity, mental health conditions, poor symptom perception and suboptimal asthma management skills including low treatment adherence. These traits are measurable and treatable. In this review, we explore current knowledge on the burden of asthma, maternal and perinatal consequences of asthma during pregnancy, the treatable traits paradigm, the prevalence of treatable traits in pregnant women with asthma, and consider how the treatable traits paradigm can be integrated into the management of asthma in pregnancy.

Abstract
Reflux asthma is an entity characterized by typical symptoms and, in some cases, is "silent"; it is more dangerous when associated with obesity and sleep apnea syndrome. Numerous studies demonstrate its high prevalence in the general population, particularly in the pediatric population, where, despite medical specialists' treatment, asthma symptoms remain poorly controlled with a high risk of acute exacerbations. This clinical study aims to show how the addition of a particular type of alginate (Deflux Plus sachets) containing hyaluronic acid and melatonin at low doses administered over a prolonged period of 6 months causes a reduction in vagal reflex stimulation of the esophagus and pulmonary microaspiration reflexes by regulating lower esophageal sphincter motility in asthmatic patients, improving the asthma control test (ATC) score. In the reported statistical analysis, receiver operating characteristic curves were performed for sensitivity and specificity for the analyzed parameters, including the ACT score, with statistically significant data p<0.0001. We conclude that combining conventional therapy for reflux asthma with alginates may improve the risk of acute asthma exacerbations and dynamic lung volumes.

Abstract
Asthma is the most common chronic disease in childhood. Overweight and obesity are included among the comorbidities considered in patients with difficult-to-treat asthma, suggesting a specific phenotype of the disease. Therefore, the constant increase in obesity prevalence in children and adolescents raises concerns about the parallel increase of obesity-associated asthma. The possible correlation between obesity and asthma has been investigated over the last decade by different authors, who suggest a complex multifactorial relationship. Although the particular non-eosinophilic endotype of obesity-related asthma supports the concept that high body weight precedes asthma development, there is ongoing debate about the direct causality of these two entities. A number of mechanisms may be involved in asthma in combination with obesity disease in children, including reduced physical activity, abnormal ventilation, chronic systemic inflammation, hormonal influences, genetics and additional comorbidities, such as gastroesophageal reflux and dysfunctional breathing. The identification of the obesity-related asthma phenotype is crucial to initiate specific therapeutic management. Besides the cornerstones of asthma treatment, lifestyle should be optimized, with interventions aiming to promote physical exercise, healthy diet, and comorbidities. Future studies should clarify the exact association between asthma and obesity and the mechanisms underlying the pathogenesis of these two related conditions with the aim to define personalized therapeutic strategies for asthma management in this population.

Abstract
Asthma is the most common chronic respiratory disease in childhood. The long-term goals in managing asthma aim to control symptoms and prevent exacerbations, as well as to reduce side effects of therapy and mortality disease-related. Most of patients have mild to moderate asthma and respond well to standard therapies. However, a minor proportion of children with asthma has severe disease that remains uncontrolled despite optimal adherence to prescribed therapy and treatment of contributory factors, including trigger exposures and comorbidities, which can mimic or worsen asthma and contribute to exacerbations and poor quality of life. Evaluation of comorbidities is fundamental to optimize the management of the disease in a subgroup of patients with poor responder asthma. The overall aim of this article is to describe characteristics of main pediatric severe asthma comorbidities reported in literature, giving clinicians tools to recognize and manage properly these conditions.

Abstract
OBJECTIVE To investigate worldwide practices of otolaryngologists in the management of laryngopharyngeal reflux (LPR). METHODS An online survey was sent on the management of LPR to members of many otolaryngological societies. The following aspects were evaluated: LPR definition, prevalence, clinical presentation, diagnosis, and treatment. RESULTS A total of 824 otolaryngologists participated, spread over 65 countries. The symptoms most usually attributed to LPR are cough after lying down/meal, throat clearing and globus sensation while LPR-related findings are arytenoid erythema and posterior commissure hypertrophy. Irrespective to geography, otolaryngologists indicate lack of familiarity with impedance pH monitoring, which they attribute to lack of knowledge in result interpretation. The most common therapeutic regimens significantly vary between world regions, with a higher use of H2 blocker in North America and a lower use of alginate in South America. The duration of treatment also significantly varies between different regions, with West Asia/Africa and East Asia/Oceania otolaryngologists prescribing medication for a shorter period than the others. Only 21.1% of respondents are aware about the existence of nonacid LPR. Overall, only 43.2% of otolaryngologists believe themselves sufficiently knowledgeable about LPR. CONCLUSIONS LPR knowledge and management significantly vary across the world. International guidelines on LPR definition, diagnosis, and treatment are needed to improve knowledge and management around the world. LEVEL OF EVIDENCE N.A. Laryngoscope, 131:E1589-E1597, 2021.

Abstract
INTRODUCTION Obesity-associated asthma (OA) is frequently severe, with an increased rate of hospitalizations, numerous comorbidities and low response to corticosteroids. Despite progress in applying for personalized medicine in asthma, no specific recommendations exist for the management of OA. AREAS COVERED The aim of this review is to summarize recent data about the relationship obesity-asthma, describe clinical characteristics, potential mechanisms involved and possible therapeutic interventions to improve OA outcomes. Extensive research in the PubMed was performed using the following terms: "asthma and obesity" and "obese asthma" in combination with "phenotypes", "airway inflammation", "biomarkers", "lung function", "weight loss", "lifestyle interventions", "therapies" Currently two phenotypes are described. Early-onset atopic asthma is conventional allergic asthma aggravated by the pro-inflammatory properties of adipose tissue in excess, while late-onset non-atopic asthma is due to airway dysfunction as a consequence of the chronic lung compression caused by the obese chest walls. Previous data showed that different therapeutic strategies used in weight loss have a positive impact on OA outcomes. EXPERT OPINION The presence of a multidisciplinary team (chest physician, nutritionist, exercise physiologist, physiotherapist, psychologist, bariatric surgeon) and the collaboration between different specialists are mandatory to optimize the management and to apply the personalized medicine in OA.

Abstract
INTRODUCTION Occupational asthma is a disease where the pathophysiological characteristics of asthma are linked to repeated exposure to a sensitizing agent present in the workspace. Assessment of patients with severe asthma to identify and manage comorbidities improves asthma control and is recommended in international guidelines on the management of severe asthma. CASE REPORT We report the case of a 49-year-old patient, nonsmoker, without atopy, who had severe work-related asthma due to exposure to isocyanates, which was uncontrolled despite the avoidance of the occupational exposure and maximal medical treatment. A systematic assessment for possible comorbidities revealed gastroesophageal reflux and obstructive sleep apnea syndrome. The specific management of these two comorbidities led to an improvement of asthma control with a reduction in the number of exacerbations, a reduced burden of treatment and a resumption of employment. CONCLUSIONS As with all cases of severe asthma, the assessment of comorbidities must be systematic in the presence of an occupational asthma which persists after the cessation of the occupational exposure. The management of these comorbidities can lead to an improvement in asthma control and severity.

Abstract
BACKGROUND Recent data among pediatric otolaryngology patients showed unexplained higher rates of serious perioperative respiratory adverse events (PRAE) in black children compared to their white peers. We evaluated whether preoperative respiratory comorbidity (PRC) burden contributes to racial disparity in serious PRAE in children undergoing non-otolaryngologic procedures. METHODS Rates of serious PRAE (laryngospasm and/or bronchospasm) were compared across racial groups in a retrospective cohort of black and white children (N = 18538; black 10%) who underwent various elective, non-otolaryngologic procedures between 2007 and 2014 at a US tertiary Children's hospital. Self-reported race was the primary exposure while age, gender, recent upper respiratory tract infection, use of endotracheal intubation, PRC burden and an interaction term between PRC and race were covariates. RESULTS Serious PRAE occurred in 9.6% of black children and 6.6% of white children. Although there was no significant difference in age between the groups, being black (odds ratio (OR) 1.70; 95% confidence interval (CI) 1.11-2.62) was independently associated with serious PRAE. Similarly, baseline PRC was independently linked (p < 0.001) with serious PRAE. Notably, there was no significant (p = 0.454) interactions between race and PRC and serious PRAE in our subjects. CONCLUSION Race and PRC are important considerations in the risk of serious PRAE and black children are especially at risk compared to their white peers. Children, with PRC (particularly those with SDB and asthma) are also at risk suggesting that due consideration should be given to these factors in the perioperative care of children undergoing elective surgical procedures. Mechanisms underlying these associations deserve further evaluation.

Abstract
Obesity is an important global health issue for both children and adults. Obesity increases the prevalence and incidence of asthma and also increases the risk for severe asthma. Here we describe the features of severe asthma phenotypes for which obesity is a defining characteristic, including steroid resistance, airway inflammation, and co-morbidities. We also review current concepts regarding the mechanistic basis for the impact of obesity in severe asthma, including possible roles for vitamin D deficiency, systemic inflammation, and the microbiome. Finally, we describe data indicating a role for diet, weight loss, and exercise in the treatment of severe asthma with obesity. Better understanding of the mechanistic basis for the role of obesity in severe asthma could lead to new therapeutic options for this population.

Abstract
There is increasing prevalence of both asthma and obesity in children globally in recent years. Various epidemiological studies link obesity as a risk factor for asthma and suggest a possible causal association. Obesity asthma phenotype is considered as distinct in view of greater severity and poor asthma control. Various mechanisms underlying this phenotype have been suggested including mechanical effects of obesity and systemic inflammation, but still the exact mechanism is unclear. Also, the comorbidities like gastroesophageal reflux disease (GERD) and sleep disordered breathing (SDB) lead to inflammation in airways and contribute to asthma obesity association. A better understanding of mechanisms by which obesity and GERD lead to inflammation in airways and increase the risk of asthma may provide insight towards targeted treatment approach of these patients.

Abstract
The older population has seen the greatest increase in the prevalence of current asthma in recent years. Asthma may begin at any age and when it occurs at an advanced as opposed to a young age, it is often nonatopic, severe, and unremitting. Unfortunately, geriatric-specific guidelines are not available for the diagnosis and treatment of asthma. However, with objective monitoring, avoidance of asthma triggers, appropriate pharmacotherapy, and patient education, the disease can be managed successfully.
