ALLERGY, ASTHMA, AND CLINICAL IMMUNOLOGY : OFFICIAL JOURNAL OF THE CANADIAN SOCIETY OF ALLERGY AND CLINICAL IMMUNOLOGY 2023; 19:73. [PMID: 37612771 PMCID: PMC10463471 DOI: 10.1186/s13223-023-00833-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Accepted: 08/06/2023] [Indexed: 08/25/2023]
Abstract
BACKGROUND Asthma is a chronic airway inflammatory disease that affects millions of Canadians and often contributes to higher levels of anxiety among patients. Since the coronavirus disease 2019 (COVID-19) pandemic was a time of increased anxiety and fear among the Canadian population, it was thought that those with asthma may experience heightened anxiety levels due to uncertain access to care, the potential to misinterpret asthma symptoms for symptoms of COVID-19 (or vice versa), and the concern about being treated differently by those around them when experiencing asthma symptoms. Therefore, this study sought to perform a cross-sectional analysis of the asthma-anxiety relationship in adults with and without asthma in the unique context of the COVID-19 pandemic from a Canadian perspective. METHODS This study employed the COVID-19 Associated Anxiety in Allergic Rhinitis and Asthma patients Experiencing Symptoms (CAAARES) survey, consisting of COVID-19-specific questions, the Generalized Anxiety Disorder Assessment-7 (GAD-7) and the Asthma Control Questionnaire-6 (ACQ-6). Data collection occurred through the Qualtrics XM platform and data analyses were conducted with the IBM SPSS Statistics 28 software. RESULTS A total of 741 valid responses were collected (asthma group, n = 244; control group, n = 497). 31.6% and 26.2% of respondents in the asthma and control groups, respectively, met the diagnostic criteria for GAD. There was no significant difference (p = .067) in mean GAD-7 scores between the two groups. A Hierarchal Multiple Regression (HMR) model was developed, and neither asthma status nor ACQ-6 score had a significant predictive effect on the GAD-7 score. There was a statistically significant (p < .001) weak positive correlation (r = .22) between GAD-7 and ACQ-6 scores. In a simple mediation (SMM) model, perceived COVID-19 stress of others was not identified as a significant mediator of the relationship between ACQ-6 and GAD-7 (indirect effect β = 0.014). CONCLUSION Our study of a Canadian cohort demonstrates elevated levels of anxiety overall, amongst both asthma and control groups. While AR status was significantly greater in the asthma group, it was not a significant predictive variable of GAD-7 score. Our data suggests that COVID-19-specific factors appear to have a greater contribution to anxiety than asthma status or control.

Abstract
OBJECTIVE Anxiety is highly prevalent in individuals with asthma. Asthma symptoms and medication can exacerbate anxiety, and vice versa. Unfortunately, treatments of comorbid anxiety and asthma are largely lacking. A problematic feature common to both conditions is hyperventilation. It adversely affects lung function and symptoms in asthma and anxiety. We examined whether a treatment to reduce hyperventilation, shown to improve asthma symptoms, also improves anxiety in asthma patients with high anxiety. METHOD One hundred twenty English- or Spanish-speaking adult patients with asthma were randomly assigned to either Capnometry-Assisted Respiratory Training (CART) to raise P co2 or feedback to slow respiratory rate (SLOW). Although anxiety was not an inclusion criterion, 21.7% met clinically relevant anxiety levels on the Hospital Anxiety and Depression Scale (HADS). Anxiety (HADS-A) and depression (HADS-D) scales, anxiety sensitivity (Anxiety Sensitivity Index [ASI]), and negative affect (Negative Affect Scale of the Positive Affect Negative Affect Schedule) were assessed at baseline, posttreatment, 1-month follow-up, and 6-month follow-up. RESULTS In this secondary analysis, asthma patients with high baseline anxiety showed greater reductions in ASI and PANAS-N in CART than in SLOW ( p values ≤ .005, Cohen d values ≥ 0.58). Furthermore, at 6-month follow-up, these patients also had lower ASI, PANAS-N, and HADS-D in CART than in SLOW ( p values ≤ .012, Cohen d values ≥ 0.54). Patients with low baseline anxiety did not have differential outcomes in CART than in SLOW. CONCLUSIONS For asthma patients with high anxiety, our brief training designed to raise P co2 resulted in significant and sustained reductions in anxiety sensitivity and negative affect compared with slow-breathing training. The findings lend support for P co2 as a potential physiological target for anxiety reduction in asthma. TRIAL REGISTRATION Clinicaltrials.gov Identifier: NCT00975273 .

Abstract
Multiple Sclerosis is a chronic neurological disease characterized by demyelination and axonal loss. This pathology, still largely of unknown etiology, carries within it a complex series of etiopathogenetic components of which it is difficult to trace the origin. An inflammatory state is likely to be the basis of the pathology. Crucial elements of the inflammatory process are the interactions between platelets and mast cells as well as the bacterial component of the intestinal microbiota. In addition, the involvement of mast cells in autoimmune demyelinating diseases has been shown. The present work tries to hang up on that Ariadne’s thread which, in the molecular complexity of the interactions between mast cells, platelets, microbiota and inflammation, characterizes Multiple Sclerosis and attempts to bring the pathology back to the causal determinism of psychopathological phenomenology. Therefore, we consider the possibility that the original error of Multiple Sclerosis can be investigated in the genetic origin of the depressive pathology.

Abstract
Anxiety disorders are debilitating psychological disorders characterized by a wide range of cognitive and somatic symptoms. Anxiety sufferers have a higher lifetime prevalence of various medical problems. Chronic medical conditions furthermore increase the likelihood of psychiatric disorders and overall dysfunction. Lifetime rates of cardiovascular, respiratory, gastrointestinal, and other medical problems are disproportionately high in anxiety and panic/fear sufferers. The heightened comorbidity is not surprising as many symptoms of anxiety and panic/fear mimic symptoms of medical conditions. Panic disorder specifically is strongly linked to medical conditions due to its salient somatic symptoms, such as dyspnea, dizziness, numbness, chest pain, and heart palpitations, all of which can signal danger and deterioration for chronic disease sufferers. This chapter identifies shared correlates of medical illness and anxiety disorders and evidence for misinterpretation of symptoms as medically relevant and offers an analysis of implications for treatment of both types of conditions. We will concentrate on medical conditions with high associations for anxiety and panic by aspects of symptomatology, specifically neurological disorders (fibromyalgia, epilepsy, cerebral palsy), diabetes, gastrointestinal illness (irritable bowel syndrome, gastroesophageal reflux disease), and cardiovascular and respiratory illnesses (asthma).

Abstract
Objective: Considering that unknown psychopathology might play a role in the management of pediatric asthma, this study examines how self-esteem and psychosocial family environment (child-raising attitudes and parental coping strategies) influence the physical and psychosocial well-being of these children. Hence, this paper aims to predict psychosocial factors influencing health-related quality-of-life (HRQL) in children with asthma without a documented history of mental illness. Methods: 32 patients with asthma and 32 controls aged 8-18 years were included in the study. All participants were largely middle-income, Caucasian school-aged children. The child-raising attitudes examined were: dependency, egalitarianism/democratic attitude, rejection of the homemaking role, marital conflict, and strictness/authoritarianism. The parental coping strategies were; social support seeking, problem-solving attitude and avoidance. Results: Psychiatric comorbidity was present in 72% of asthma patients and 22% of the controls. The most common mental illness identified was generalized anxiety disorder; 32% vs 13%, respectively. Dependency was the only parental child-raising attitude that differed significantly between groups (47 ± 8 vs 41 ± 11, respectively. p = 0.035). There was a negative correlation between the PARI dependency subscale and the total HRQL score according to the parents (rp= -0.39, p = 0.027). The most influential factors connected with the total HRQL score in asthma were Rosenberg self-esteem scale score, presence of psychopathology and dependency according to the child. Conclusions: Simple ways to overcome emotional dependency and fortify self-esteem (exercises promoting self-awareness, opportunities cultivating decision-making, and a considerable freedom-of-choice to experience consequences) worth recommending to parents of children with asthma. Patients with suspected mental illness must be referred for psychiatric evaluations.

Abstract
OBJECTIVE To review the literature regarding the effects of caregiver depression on childhood asthma and integrate the findings into a multilevel model of pathways by which these effects occur to further the understanding of the complex biopsychosocial nature of childhood asthma and the key role that is played by caregiver depression. DATA SOURCES PubMed was searched for articles published from 2007 to the present (10-year search), and Google Scholar was searched for articles published in 2017 and 2018 to identify the most recent publications. STUDY SELECTIONS Studies selected were recent, empirical, or meta-analytic, conducted in humans, and had specific relevance to one or more of the identified pathways. Articles published before 2007 were included if deemed essential because they addressed key pathways, for which there were no more recent articles. RESULTS Review of the literature substantiates that caregiver depression plays a key role in the socioeconomic, familial, psychological, and biological cascade of effects on childhood asthma. Childhood asthma outcomes are affected indirectly by socioeconomic status and family stress mediated by caregiver depression, which affects disease management, and/or stress and depression in the child, which, in turn, affect asthma through alterations in immune modulation and autonomic regulation. CONCLUSION Findings indicate that future research should concentrate on mediators and moderators to further clarify the complex interplay of these factors that affect childhood asthma. The findings also have substantial translational implications. Given that child stress and depression contribute to asthma disease activity and that treating caregiver depression improves child stress and depression, there is strong rationale for treating depressed caregivers of children with asthma as a component means of improving childhood asthma control.

Abstract
Background Asthma is the most common obstructive airway disease in children and adults. Nasal high flow (NHF) is a recent device that is now used as a primary support for respiratory distress. Several studies have reported use of NHF as a respiratory support in status asthmaticus; however, there are no data to recommend such practice. We therefore conducted this preliminary study to evaluate NHF therapy for children with status asthmaticus admitted to our PICU in order to prepare a multicentre randomized controlled study. Results Between November 2009 and January 2014, 73 patients with status asthmaticus were admitted to the PICU, of whom 39 (53%) were treated with NHF and among these 10 (26%) presented severe acidosis at admission (pH < 7.30). Thirty-four less severe children (41%) were treated with standard oxygen. For one child (2.6%) NHF failed and was then switched to non-invasive ventilation. NHF was discontinued in another patient because of the occurrence of pneumothorax after 31 h with NHF; the patient was then switched to standard oxygen therapy. Mean ± SD heart rate (165 ± 21 vs. 141 ± 25/min, p < 0.01) and respiratory rate (40 ± 13 vs. 31 ± 8/min, p < 0.01) decreased significantly, and blood gas improved in the first 24 h. In the subgroup of patients with acidosis, median [IQR] pH increased significantly between hour 0 and 2 (7.25 [7.21–7.26] vs. 7.30 [7.27–7.33], p = 0.009) and median [IQR] pCO2 decreased significantly (7.27 kPa [6.84–7.91 vs. 5.85 kPa [5.56–6.11], p = 0.007). No patient was intubated. Conclusion This retrospective study showed the feasibility and safety of NHF in children with severe asthma. Blood gas and clinical parameters were significantly improved during the first 24 h. NHF failed in only two patients, and none required invasive ventilation.

Abstract
BACKGROUND Psychological stress has long been suspected to have a deleterious effect on asthma, with acute psychological stress being associated with physiological responses in asthma patients. OBJECTIVES The purpose of this systematic review was to provide a narrative synthesis of the impact of acute laboratory psychological stress on physiological responses among asthma patients. METHODS An extensive search was conducted by two independent authors using Pubmed, PsycINFO, PsyArticles and the Cochrane Library electronic databases (up to September 2016). English and French articles which assessed physiological responses during or post-stress and compare them to baseline or pre-stress values were included. RESULTS Thirty-two studies met the inclusion criteria. Studies indicated that exposure to active stressors (e.g., arithmetic tasks) was associated with an increase in sympathetic nervous system (SNS) responses, cortisol, and inflammatory responses, but had little effect on the caliber of the bronchi. Exposure to passive stressors (e.g., watching stressful movies or pictures) was also associated with an increase in SNS responses and with mild bronchoconstriction. However, a paucity of data for passive stressors limited conclusions on other measures. CONCLUSIONS In patients with asthma, both active and passive stressors seem to be associated with an increased activation of the SNS. Passive stressors seem to have a more immediate, deleterious impact on the airways than active stressors, but the latter may be associated with delayed inflammatory driven an asthma exacerbation. Further studies are needed to understand the impact of acute stressors on the physiological mechanisms associated with asthma, particularly HPA and immune markers.

Abstract
Panic disorder (PD) is unique among the anxiety disorders in that panic symptoms are primarily of a physical nature. Consequently, comorbidity with medical illness is significant. This review examines the association between PD and medical illness. We identify shared pathophysiological and psychological correlates and illustrate how physiological activation in panic sufferers underlies their symptom experience in the context of the fight-or-flight response and beyond a situation-specific response pattern. We then review evidence for bodily symptom perception accuracy in PD. Prevalence of comorbidity for PD and medical illness is presented, with a focus on respiratory and cardiovascular illness, irritable bowel syndrome, and diabetes, followed by an outline for potential pathways of a bidirectional association. We conclude by illustrating commonalities in mediating mechanistic pathways and moderating risk factors across medical illnesses, and we discuss implications for diagnosis and treatment of both types of conditions.

Abstract
Relaxation techniques can lead to symptom reduction and improved pulmonary functioning in asthmatics, although the mechanism is not clear. One possibility is by influencing cortisol secretion, as cortisol is implicated in inflammatory processes and relaxation has been shown to alter cortisol secretion in healthy individuals. This study explored the effect of relaxation training on cortisol levels and cortisol reactivity to stress in asthmatics. Twenty adult asthmatics participated for 21 days in their natural environment, and received relaxation training halfway through the study. Cortisol was assessed from saliva five times per day for three weeks. Relaxation training was successful, but did not lead to the hypothesized reduction in overall cortisol levels. Participants using corticosteroid medication showed increases in cortisol after relaxation, whereas those not using corticosteroids showed decreases in cortisol ( p< .05). Relaxation altered the cortisol reactivity to stress ( p= .007); before relaxation training cortisol levels increased after a stressor, whereas following relaxation training cortisol levels decreased after a stressor. This study suggests that relaxation training can influence cortisol secretion in asthmatics, but that these effects differ from those observed in healthy individuals and may be influenced by corticosteroid medication use.

Abstract
BACKGROUND Psychosocial stress and negative affect have been linked to asthma exacerbations, but longitudinal studies demonstrating a daily life association between negative affect and airway nitric oxide are missing. OBJECTIVE The longitudinal association between negative mood fluctuations, exhaled nitric oxide, and lung function in asthma was examined. METHODS Self-assessments of the fraction of exhaled nitric oxide (FeNO), spirometry (forced expiratory volume in the first second, FEV1), negative mood, and daily activities were obtained from 20 patients with asthma for 2 months, resulting in 1108 assessments for the analyses (approximately 55 per patient). Concurrent and prospective associations between FeNO, FEV1, and negative mood were analyzed using mixed effects regression models for longitudinal data. RESULTS Negative mood was positively associated with changes in FeNO during the same day, and to a stronger extent when prior day negative mood was included in the prediction. FeNO and negative mood were positively associated with same-day FEV1, with the latter relation being partially mediated by changes in FeNO. Associations between FeNO and FEV1 were stronger in younger patients, with earlier onset of asthma, or with lower asthma control. Findings were not changed when controlling for physical activity, medication, cold symptoms, air pollution, and hours spent outside. CONCLUSION Daily life changes of negative mood in asthma are positively associated with FeNO changes and FeNO increases are associated with a mild bronchodilation. These findings indicate that psychological influences need to be considered when using FeNO as indicator of airway inflammation and guide for treatment decisions.

Abstract
OBJECTIVE Earlier studies found chronic nonspecific lung disease (CNSLD) to be associated with depressive symptoms. We aimed to assess whether the association between CNSLD and depressive symptoms varies between ethnic groups. METHODS We used questionnaire data from 10916 participants of the HELIUS study in Amsterdam from six different ethnic groups. We applied logistic regression analysis to determine the association between CNSLD and depressive symptoms and interaction terms to test whether this association varied between ethnic groups. RESULTS CNSLD prevalence was higher among South-Asian Surinamese, Turkish and Moroccans (10.1% to 12.5%) than African Surinamese, Dutch and Ghanaians (4.8% to 6.3%). The prevalence of depressive symptoms was higher among participants with CNSLD (28.4% vs. 13.7%). This association was not significantly different between ethnic groups. The absolute prevalence of depressive symptoms was higher among the CNSLD patients from ethnic minority groups (19.2 % to 35.6%) as compared with the Dutch-origin majority group (11.2%). CONCLUSIONS CNSLD is associated with a high risk of depressive symptoms, especially among the five ethnic minority groups. These results imply a need to monitor the mental health of CNSLD patients in particular when a patient is from an ethnic minority group.

Abstract
OBJECTIVES Asthma is a chronic condition affecting 300 million people worldwide. Management involves adherence to pharmacological treatments such as corticosteroids and β-agonists, but residual symptoms persist. As asthma symptoms are exacerbated by stress, one possible adjunct to pharmacological treatment is expressive writing (EW). EW involves the disclosure of traumatic experiences which is thought to facilitate cognitive and emotional processing, helping to reduce physiological stress associated with inhibiting emotions. A previous trial reported short-term improvements in lung function. This study aimed to assess whether EW can improve lung function, quality of life, symptoms, and medication use in patients with asthma. METHODS Adults (18-45 years) diagnosed as having asthma requiring regular inhaled corticosteroids were recruited from 28 general practices in South East England (n = 146). In this double-blind randomized controlled trial, participants were allocated either EW or nonemotional writing instructions and asked to write for 20 minutes for 3 consecutive days. Lung function (forced expired volume in 1 second [FEV1]% predicted), quality of life (Mark's Asthma Quality of Life Questionnaire), asthma symptoms (Wasserfallen Symptom Score Questionnaire), and medication use (inhaled corticosteroids and β-agonist) were recorded at baseline, 1, 3, 6, and 12 months. RESULTS Hierarchical linear modeling indicated no significant main effects between time and condition on any outcomes. Post hoc analyses revealed that EW improved lung function by 14% for 12 months for participants with less than 80% FEV1% predicted at baseline (β = 0.93, p = .002) whereas no improvement was observed in the control condition (β = 0.10, p = .667). CONCLUSIONS EW seems to be beneficial for patients with moderate asthma (<80% FEV1% predicted). Future studies of EW require stratification of patients by asthma severity.

Abstract
A male patient presented with bronchospasm and acute respiratory distress. The patient had presented 2 previous episodes of severe bronchospasm following abdominal surgery, leading twice to intubation, mechanical ventilation, and conventional sedation. As the patient positively rejected a third episode of intubation + mechanical ventilation, noninvasive ventilation (pressure support = 8 cm H₂O, positive end-expiratory pressure = 10 cm H₂O), inhaled therapy, and clonidine orally (≈ 4 μg/kg) were combined. Over 1 to 2 hours, the acute respiratory distress disappeared. Noninvasive ventilation was discontinued on the next morning (day 2). The patient was discharged from the critical care unit on day 3 on good condition but died at a later interval from iterative bronchospasm. Evidence-based documentation of the effects of alpha-2 agonists in the setting of acute bronchospasm in the emergency department or status asthmaticus in the critical care unit is awaited.

Abstract
OBJECTIVE This study sought to determine whether social integration, defined as number of social roles, is associated with better pulmonary function in the elderly and which roles are associated with greatest benefit. It also examined pathways that connect social integration to better lung health. METHODS High functioning men (n = 518) and women (n = 629) ages 70-79 were recruited as part of the MacArthur Study of Successful Aging, and data were collected on social roles as well as pulmonary function as assessed by peak expiratory flow rate (PEFR). Multiple regressions predicting PEFR from the number of social roles controlled for age, sex, race, education, weight, and height. Physiological, behavioral, social, and psychological factors were tested as mediators of the association between the number of social roles and PEFR. RESULTS More social roles were associated with better PEFR. Analysis of specific roles indicated that marriage was the strongest positive correlate of PEFR. However, greater numbers of roles were also associated with better PEFR independent of marriage. Being a relative or friend were each also individually associated with better PEFR. Even so, greater numbers of social roles were associated with better PEFR independent of relative and friend. The data were consistent with greater happiness, not smoking, and more physical activity acting as pathways linking the number of roles to PEFR. CONCLUSIONS Number of social roles is an important correlate of healthy lung function in the elderly. This association may be driven by healthier behaviors and greater feelings of well-being.

Abstract
BACKGROUND Few data are available that evaluate the relationship among asthma exacerbations, asthma triggers, and asthma-related quality of life (QoL). OBJECTIVE To evaluate the impact of asthma exacerbations and asthma triggers on QoL. METHODS Patients with severe or difficult-to-treat asthma, ages ≥ 13 years (n = 2679) from the TENOR (The Epidemiology and Natural History of Asthma: Outcomes and Treatment Regimens) 3-year observational study were included. Exacerbations were defined hierarchically in descending order of severity (hospitalization, emergency department [ED] visit, steroid burst, no exacerbation) by using data from months 6 and 12. The total number (frequency) of exacerbations was assessed. Asthma-related QoL was measured at month 12 by using the Mini-Asthma QoL Questionnaire (Mini-AQLQ); self-reported asthma triggers were collected at baseline and annually. We used 1-way ANOVA to test for differences in Mini-AQLQ domain scores across asthma exacerbation severity, the total number of asthma exacerbations, and the number of asthma triggers. RESULTS A significant decrease (P < .001) in Mini-AQLQ domain scores was seen with increasing severity of asthma exacerbation (no exacerbation, steroid burst, ED visit, and hospitalization); symptom (5.5, 4.8, 4.3, and 4.2), activity (5.8, 5.2, 4.6, and 4.4), emotional (5.6, 5.0, 4.4, and 4.2), exposure (5.0, 4.5, 4.0, and 3.9); and overall (5.5, 4.9, 4.3, and 4.1). Increasing exacerbation frequency and the number of baseline asthma triggers also were associated with significant decreases in Mini-AQLQ domain scores. An increasing number of asthma triggers were associated with an increase in severity and frequency of exacerbations. CONCLUSION Avoidance of asthma triggers may reduce exacerbation rates and improve asthma-related QoL in patients with severe or difficult-to-treat asthma. Interventional studies are warranted to further explore these outcomes.

Abstract
Inflammatory and neuroinflammatory processes are increasingly recognized as critical pathophysiologic steps in the development of multiple chronic diseases and in the etiology of persistent pain and depression. Mast cells are immune cells now viewed as cellular sensors in inflammation and immunity. When stimulated, mast cells release an array of mediators to orchestrate an inflammatory response. These mediators can directly initiate tissue responses on resident cells, and may also regulate the activity of other immune cells, including central microglia. New evidence supports the involvement of peripheral and central mast cells in the development of pain processes as well as in the transition from acute, to chronic and neuropathic pain. That behavioral and endocrine states can increase the number and activation of peripheral and brain mast cells suggests that mast cells represent the immune cells that peripherally and centrally coordinate inflammatory processes in neuropsychiatric diseases such as depression and anxiety which are associated with chronic pelvic pain. Given that increasing evidence supports the activated mast cell as a director of common inflammatory pathways/mechanisms contributing to chronic and neuropathic pelvic pain and comorbid neuropsychiatric diseases, mast cells may be considered a viable target for the multifactorial management of both pain and depression.

Abstract
Asthma is a biomedical disorder whose presentation can be markedly influenced by neurological and psychological factors. This chapter describes several approaches that provide insight into the role of psychological factors and brain function in asthma. These include the study of placebo responses and recent explorations using functional neuroimaging during the onset of asthma symptoms. Although the specific mechanisms involved remain uncertain, we are gaining an appreciation for some of the neurocircuitry that is involved. The insula and ACC may modulate inflammatory processes by their influence on neuroendocrine responses to stress, including highly studied effects on the HPA axis and its physiologic responses. However much we have recently learned, it is clear that further study of this topic is critical to fully explicate the role of the brain in asthma.

Abstract
OBJECTIVE The fraction of exhaled nitric oxide (FeNO) has been widely used as a marker of airway inflammation in asthma in recent years. However, NO serves multiple functions throughout the organism, and various influences on FeNO levels beyond inflammation have been documented. Emerging literature indicates that psychological processes are systematically linked to FeNO. DATA SOURCES Academic Search Complete, PubMed, PsychArticles, and PsychInfo databases. STUDY SELECTIONS Relevant studies were identified using keywords exhaled nitric oxide paired with psychological stress, stress psychology, emotion, major depression, anxiety, or psychopathology. Studies measuring FeNO during naturalistic observation of emotion and stress, laboratory stress and emotion-induction protocols, and correlational designs using psychological questionnaires were included. RESULTS Acute stress, anxiety, and negative affect have been repeatedly linked with higher FeNO levels, whereas more prolonged states of stress, in particular depression, have been associated with lower FeNO levels. The literature on FeNO is paralleled by research on NO in the cardiovascular and central nervous systems, which also shows systematic associations with psychosocial variables. Potential mechanisms of association include stimulation of NO release from different cells, including the epithelia and macrophages, through noradrenaline, interferon-γ, or vascular endothelial growth factor, changes in oxidative stress or arginase levels, or facilitation of diffusion by mechanical factors. CONCLUSION Psychosocial factors may need to be considered in the interpretation of longitudinal FeNO changes in monitoring and management of patients with asthma. The distinction between constitutive and inducible sources of NO will be essential for future research.

Abstract
During functional magnetic resonance imaging studies of meditation the cortical salience detecting and executive networks become active during "awareness of mind wandering," "shifting," and "sustained attention." The anterior cingulate (AC) is activated during "awareness of mind wandering." The AC modulates both the peripheral sympathetic nervous system (SNS) and the central locus coeruleus (LC) norepinephrine systems, which form the principal neuromodulatory system, regulating in multiple ways both neuronal and non-neuronal cells to maximize adaptation in changing environments. The LC is the primary source of central norepinephrine (C-NE) and nearly the exclusive source of cortical norepinephrine. Normally activated by novel or salient stimuli, the AC initially inhibits the SNS reflexively, lowering peripheral norepinephrine and activates the LC, increasing C-NE. Moderate levels of C-NE enhance working memory through alpha 2 adrenergic receptors, while higher levels of C-NE, acting on alpha 1 and beta receptors, enhance other executive network functions such as the stopping of ongoing behavior, attentional set-shifting, and sustained attention. The actions of the AC on both the central and peripheral noradrenergic systems are implicated in the beneficial effects of meditation. This paper will explore some of the known functions and interrelationships of the AC, SNS, and LC with respect to their possible relevance to meditation.

Abstract
OBJECTIVE This review examines the evidence for psychosocial influences in asthma and behavioral medicine approaches to its treatment. METHOD We conducted a systematic review of the literature on psychosocial influences and the evidence for behavioral interventions in asthma with a focus on research in the past 10 years and clinical trials. Additional attention was directed at promising new developments in the field. RESULTS Psychosocial factors can influence the pathogenesis and pathophysiology of asthma, either directly through autonomic, endocrine, immunological, and central nervous system mechanisms or indirectly through lifestyle factors, health behaviors, illness cognitions, and disease management, including medication adherence and trigger avoidance. The recent decade has witnessed surging interest in behavioral interventions that target the various pathways of influence. Among these, self-management training, breathing training, and exercise or physical activation programs have proved particularly useful, whereas other essential or promising interventions, such as smoking cessation, dietary programs, perception and biofeedback training, and suggestive or expressive psychotherapy, require further, more rigorous evaluation. Given the high comorbidity with anxiety and mood disorders, further evaluation of illness-specific cognitive behavior therapy is of particular importance. Progress has also been made in devising community-based and culturally tailored intervention programs. CONCLUSION In concert with an essential medication treatment, behavioral medicine treatment of asthma is moving closer toward an integrated biopsychosocial approach to disease management.

Stress and infections have long been independently associated with asthma pathogenesis and exacerbation. Prior research has focused on the effect of psychological stress on Th cells with particular relevance to atopic asthma. In this review, we propose new perspectives that integrate the role of infection in the relationship between psychological stress and asthma. We highlight the essential role of the mucosal epithelia of the airways in understanding the interaction between infections and the stress-asthma relationship. In addition, we review findings suggesting that psychological stress not only modulates immune processes, but also the pathogenic qualities of bacteria, with implications for the pathogenesis and exacerbation asthma.

Abstract
Emotions have been shown to play a critical role in health outcomes, but research on this topic has been limited to studies in industrialized countries, which prevents broad generalizations. This study assessed whether emotion-health connections persist across various regions, including less-developed countries, where the degree to which people's fundamental needs are met might be a better predictor of physical well-being. Individuals from 142 countries (N = 150,048) were surveyed about their emotions, health, hunger, shelter, and threats to safety. Both positive and negative emotions exhibited unique, moderate effects on self-reported health, and together, they accounted for 46.1% of the variance. These associations were stronger than the relative impact of hunger, homelessness, and threats to safety and were not simply attributable to countries' gross domestic products (GDPs). Furthermore, connections between positive emotion and health were stronger in low-GDP countries than in high-GDP countries. Our findings suggest that emotion matters for health around the globe and may in fact be more critical in less-developed areas.

Abstract
OBJECTIVE The aim of the study was to investigate the effectiveness and feasibility of conducting a complementary 8-week comprehensive lifestyle modification program (CLMP) compared to standard care in patients with bronchial asthma over a 6-month period. METHODS This was a randomized controlled pilot trial with two groups: intervention (N = 15) group and attention-placebo control (N = 14) group. The intervention group received an 8-week CLMP in addition to standard care. Quality of life, asthma control, lung function, reduction of rescue medication, perceived stress, and psychosocial and spiritual status were measured at the end of the intervention and at the 4-month follow-up. RESULTS In the intervention group, there was a statistically significant difference in the improvements of quality of life, asthma control, lung function, and the reduction of rescue medication intake at both the end of the intervention and at the 4-month follow-up, with no change being observed in the control group. Significant stress reduction and greater psychosocial and spiritual well-being were observed during the 8-week CLMP in the intervention group. At the end of the intervention, the measures of stress and psychological and spiritual well-being reached statistical significance. CONCLUSIONS Preliminary findings suggest that adding a CLMP to standard care in patients with bronchial asthma offers greater clinical benefit than standard care alone and also suggest that conducting a large randomized clinical trial is feasible.

Abstract
Emotional factors are an obstacle in the diagnosis and management of asthma. This review discusses three problem patterns: negative emotions in relatively normal patients with asthma; patients presenting possible functional symptoms and; patients presenting asthma in conjunction with psychiatric deviations. Negative emotions influence the symptoms and management of asthma, even in relatively normal patients. Psychogenic symptoms appear normal, but culminate in functional symptoms in a minority of patients. Diagnosing and treating asthma in patients with comorbid asthma and psychiatric symptoms is very difficult. On the one hand, treating asthma may often be just treating the emotions. On the other hand, negative emotions make the treatment of asthma guesswork. Physicians should estimate emotional influences in their patients' symptoms for an optimal evaluation of medication efficacy. Assessment and analysis of emotional factors surrounding exacerbations seems essential, e.g. emotional precipitants of asthma and asthma-evoked negative emotions. Moreover, patients should be informed about stress-induced breathlessness and the consequences of overuse of bronchodilators. When patients present with atypical symptoms, or do not properly respond to asthma medication, functional symptoms should be suspected. Psychiatric analysis may often lead to the conclusion that symptoms have a functional basis. In patients with comorbid asthma and anxiety disorders, asthma should be the focus for treatment since difficult-to-control asthma often causes anxiety problems in the first place. Moreover, panic-like symptoms in asthma are often related to sudden onset asthma exacerbations. However, in patients with comorbid asthma and depression, depression should become the focus of treatment. The reason is that optimal treatment of depressive asthmatics is probably impossible. Special issues include specific problems with children, compliance problems, and physicians' dilemmas regarding the simultaneous treatment of asthma and psychiatric symptoms.

Abstract
The mast cells are multi-effector cells with wide distribution in the different body parts and traditionally their role has been well-defined in the development of IgE-mediated hypersensitivity reactions including bronchial asthma. Due to the availability of genetically modified mast cell-deficient mice, the broadened pathophysiological role of mast cells in diverse diseases has been revealed. Mast cells exert different physiological and pathophysiological roles by secreting their granular contents, including vasoactive amines, cytokines and chemokines, and various proteases, including tryptase and chymase. Furthermore, mast cells also synthesize plasma membrane-derived lipid mediators, including prostaglandins and leukotrienes, to produce diverse biological actions. The present review discusses the pathophysiological role of mast cells in different diseases, including atherosclerosis, pulmonary hypertension, ischemia-reperfusion injury, male infertility, autoimmune disorders such as rheumatoid arthritis and multiple sclerosis, bladder pain syndrome (interstitial cystitis), anxiety, Alzheimer's disease, nociception, obesity and diabetes mellitus.

Abstract
BACKGROUND High frequency chest wall oscillation (HFCWO) is used for airway mucus clearance. The objective of this study was to evaluate the use of HFCWO early in the treatment of adults hospitalized for acute asthma or chronic obstructive pulmonary disease (COPD). METHODS Randomized, multi-center, double-masked phase II clinical trial of active or sham treatment initiated within 24 hours of hospital admission for acute asthma or COPD at four academic medical centers. Patients received active or sham treatment for 15 minutes three times a day for four treatments. Medical management was standardized across groups. The primary outcomes were patient adherence to therapy after four treatments (minutes used/60 minutes prescribed) and satisfaction. Secondary outcomes included change in Borg dyspnea score (≥ 1 unit indicates a clinically significant change), spontaneously expectorated sputum volume, and forced expired volume in 1 second. RESULTS Fifty-two participants were randomized to active (n = 25) or sham (n = 27) treatment. Patient adherence was similarly high in both groups (91% vs. 93%; p = 0.70). Patient satisfaction was also similarly high in both groups. After four treatments, a higher proportion of patients in the active treatment group had a clinically significant improvement in dyspnea (70.8% vs. 42.3%, p = 0.04). There were no significant differences in other secondary outcomes. CONCLUSIONS HFCWO is well tolerated in adults hospitalized for acute asthma or COPD and significantly improves dyspnea. The high levels of patient satisfaction in both treatment groups justify the need for sham controls when evaluating the use of HFCWO on patient-reported outcomes. Additional studies are needed to more fully evaluate the role of HFCWO in improving in-hospital and post-discharge outcomes in this population. TRIAL REGISTRATION ClinicalTrials.gov: NCT00181285.

Abstract
BACKGROUND Generalized anxiety disorder (GAD) is common among people with asthma, but its association with asthma morbidity remains unexplored. This study examined cross-sectional associations between GAD and asthma control, quality of life, and self-efficacy. METHODS Seven hundred ninety-four adults with confirmed asthma were recruited from the outpatient clinic of a university hospital. Patients underwent a sociodemographic and medical history interview (to assess health service use and medications), followed by a brief psychiatric interview (Primary Care Evaluation of Mental Disorders) to assess GAD. Patients completed questionnaires assessing asthma control, quality of life, and asthma self-efficacy and underwent spirometry. General linear models and logistic regression were used to assess associations between GAD and asthma morbidity measures, adjusting for covariates. RESULTS GAD affected 4% of the sample. The analyses revealed significant associations between GAD and worse overall asthma control (β = 0.62, standard error [SE] = 0.18, p < .001), increased bronchodilator use (β = 10.60, SE = 2.64, p < .001), worse asthma quality of life (β = -0.91, SE = 0.23, p < .001), and worse asthma self-efficacy (β = -59.56, SE = 13.59, p < .001) after the adjustment for covariates. Separate sensitivity analyses including major depressive disorder and asthma self-efficacy as additional covariates rendered many of these associations nonsignificant. There were no associations between GAD and emergency visits or hospitalizations. CONCLUSIONS GAD is associated with worse asthma morbidity independent of age, sex, smoking, and asthma severity; however, comorbid major depressive disorder and low asthma self-efficacy may account for many of these associations. Only breathlessness and the frequency of bronchodilator use were uniquely associated with GAD. Future research should examine whether treatment of GAD can affect asthma outcomes.

Abstract
Earlier research found autonomic and airway reactivity in asthma patients when they were exposed to blood-injection-injury (BII) stimuli. We studied oscillatory resistance (R(os)) in asthma and BII phobia during emotional and disease-relevant films and examined whether muscle tension counteracts emotion-induced airway constriction. Fifteen asthma patients, 12 BII phobia patients, and 14 healthy controls viewed one set of negative, positive, neutral, BII-related, and asthma-related films with leg muscle tension and a second set without. R(os), ventilation, cardiovascular activity, and skin conductance were measured continuously. R(os) was higher during emotional compared to neutral films, particularly during BII material, and responses increased from healthy over asthmatic to BII phobia participants. Leg muscle tension did not abolish R(os) increases. Thus, the airways are particularly responsive to BII-relevant stimuli, which could become risk factors for asthma patients.

Abstract
BACKGROUND Few studies have analysed the relationship between anxiety and alexithymia with functional dyspnea (FD) and its impact on quality of life and asthma control. The aim of this study was to assess the prevalence of DD in asthma, its impact on quality of life and asthma control and its relationship with anxiety and alexithymia. PATIENTS AND METHODS We performed a cross-sectional study of 264 asthmatic patients and 111 controls. Both groups completed the following questionnaires: quality of life (AQLQ), alexithymia (TAS-20), anxiety (STAI) and FD (Nijmegen). In asthmatics were evaluated: asthma severity, dyspnoea, exacerbation and control of the disease (ACT test). RESULTS 38% of asthmatics and 5.5% of non-asthmatics had FD. Asthmatics had more anxiety and were more alexithymic. Asthmatics with FD had significantly more anxiety, more alexithymia, poor control of asthma, more exacerbations and poorer quality of life, that asthma without DD. Asthmatics with an ACT<19, a score >3 in the emotion subscale of the AQLQ, who were being treated for anxiety and scored >19 on the alexithymia subscale that assesses difficulty in identifying emotions, showed ORs for FD of 2.6 (1.1-5.9), 6.8 (2.9-15.8), 4.4 (1.9-9.8) and 3.3 (1.5-7), respectively. A predictive model of FD was constructed. CONCLUSIONS We demonstrated the close relationship between anxiety, alexithymia and DD in asthmatics, as well as the significant impact of FD on the control and quality of life of this asthmatics.

Abstract
Allergy is on the rise worldwide. Asthma, food allergy, dermatitis, and systemic anaphylaxis are amongst the most common allergic diseases. The association between allergy and altered behavior patterns has long been recognized. The molecular and cellular pathways in the bidirectional interactions of nervous and immune systems are now starting to be elucidated. In this paper, we outline the consequences of allergic diseases, especially food allergy and asthma, on behavior and neural activity and on the neural modulation of allergic responses.

Abstract
Considerable individual differences exist in asthma patients' airway responses to emotional stimuli, but little is known about the generalization of such responses across situations or states of airways constriction. Fifty-four asthma patients and 25 healthy controls viewed in two separate sessions, films and blocks of pictures from each of three emotional qualities, pleasant, unpleasant, and neutral. At the beginning of each session, patients received a placebo or anti-cholinergic bronchodilator (ipratropium bromide), respectively, in a randomized double-blind design. Respiratory resistance, reactance and impedance were recorded throughout stimulus presentations with impulse oscillometry. Resistance increases showed a moderate degree of generalization across unpleasant films and pictures, unpleasant and pleasant pictures, as well as cholinergic blockade and placebo. Thus, the intensity of airway responses to unpleasant emotional stimuli is a moderately stable characteristic of asthma patients. In addition to the central airway, peripheral and extrathoracic airways may also contribute the consistency of such responses.

Abstract
Psychosocial stress alters susceptibility to infectious and systemic illnesses and may enhance airway inflammation in asthma by modulating immune cell function through neural and hormonal pathways. Stress activates the hypothalamic-pituitary-adrenal axis. Release of endogenous glucocorticoids, as a consequence, may play a prominent role in altering the airway immune homeostasis. Despite substantial corticosteroid and catecholamine plasma levels, chronic psychosocial stress evokes asthma exacerbations. Animal studies suggest that social stress induces corticosteroid insensitivity that in part may be a result of impaired glucocorticoid receptor expression and/or function. Such mechanisms likely promote and amplify airway inflammation in response to infections, allergen, or irritant exposure. This review discusses evidence of an altered corticosteroid responsive state as a consequence of chronic psychosocial stress. Elucidation of the mechanisms of stress-induced impairment of glucocorticoid responsiveness and immune homeostasis may identify novel therapeutic targets that could improve asthma management.

Abstract
Chronic psychosocial stress exacerbates asthma, but the underlying mechanisms remain poorly understood. We hypothesized that psychosocial stress aggravates allergic airway inflammation by altering innate immune cell function. The effects of stress on airway inflammation, lung function, and glucocorticoid responsiveness were studied in a novel in vivo murine model of combined social disruption stress and allergic sensitization. The effects of corticosterone were assessed on cytokine profile and glucocorticoid receptor activation in LPS-stimulated spleen cell cultures in vitro. Airway inflammation resolved 48 h after a single allergen provocation in sensitized control mice, but not in animals that were repeatedly exposed to stress before allergen challenge. The enhanced eosinophilic airway inflammation 48 h after allergen challenge in these mice was associated with increased levels of IL-5, GM-CSF, IgG1, thymus-activated and regulatory chemokine, TNF-alpha, and IL-6 in the airways and a diminished inhibition of these mediators by corticosterone in LPS-stimulated splenocyte cultures in vitro. Stress-induced reduction of the corticosteroid effects paralleled increased p65 expression and a decreased DNA-binding capability of the glucocorticoid receptor in vitro. Furthermore, glucocorticoid receptor mRNA and protein expression in the lungs of mice exposed to both stress and allergen was markedly reduced in comparison with that in either condition alone or in naive mice. Thus, exposure to repeated social stress before allergen inhalation enhances and prolongs airway inflammation and alters corticosterone responsiveness. We speculate that these effects were mediated at least in part by impaired glucocorticoid receptor expression and function.

Abstract
Individuals with asthma have twice the risk of developing mood and anxiety disorders as individuals without asthma and these psychological factors are associated with worse outcomes and greater need for medical intervention. Similarly, asthma symptom onset and exacerbation often occur during times of increased psychological stress. Remission from depression, on the other hand, is associated with improvement in asthma symptoms and decreased usage of asthma medication. Yet research aimed at understanding the biological underpinnings of asthma has focused almost exclusively on the periphery. An extensive literature documents the relationship between emotion and asthma, but little work has explored the function of affective neural circuitry in asthma symptom expression. Therefore, the following review integrates neuroimaging research related to factors that may impact symptom expression in asthma, such as individual differences in sensitivity to visceral signals, the influence of expectation and emotion on symptom perception, and changes related to disease chronicity, such as conditioning and plasticity. The synthesis of these literatures suggests that the insular and anterior cingulate cortices, in addition to other brain regions previously implicated in the regulation of emotion, may be both responsive to asthma-related bodily changes and important in influencing the appearance and persistence of symptom expression in asthma.

Abstract
Gaps in understanding of how area-based differences in exposure to violence are associated with asthma prevalence may limit the development of effective prevention programs and the identification of risk for asthma episodes. The current investigation examines the associations between sexual violence victimization and asthma episodes among US adult women across three different metropolitan settings. The association between sexual assault victimizations and asthma attacks in the past year was examined using data from the 2005, 2006, and 2007 Behavioral Risk Factor Surveillance System surveys. Cross-sectional analyses were based on adult women with current asthma (n = 4,099). Multivariate logistic regression models were used to identify associations between four categories of sexual violence victimization and asthma episodes across three categories of metropolitan and non-metropolitan settings. Our findings show that unwanted touching, attempted unwanted intercourse, forced unwanted intercourse, and any sexual violence victimization (touching, attempted intercourse, or forced intercourse) were significantly associated with asthma episodes (OR(adj.) = 3.67, 95% CI, 1.76-7.69; OR(adj.) = 1.77, 95% CI, 1.32-2.37; OR(adj.) = 2.24, 95% CI, 1.64-3.05, and OR(adj.) = 1.93, 95% CI, 1.47-2.53, respectively). While no significant differences in the associations between asthma episodes and metropolitan status were found, a significant interaction between non-metropolitan areas and attempted sexual intercourse was identified (OR(adj) = 0.53, 95% CI, 0.29-0.96). Sexual victimization appears to be an important, but understudied, correlate of asthma morbidity among adult women in the USA, suggesting that additional research is needed to better understand the associations between sexual violence, psychological distress, and asthma.

Abstract
BACKGROUND People suffering from asthmatic symptoms have a lower quality of life than those without. The aim of this study is to clarify the association of quality of life with the severity of asthma, perceived stress, and other factors such as the comorbidity of allergic diseases among young adults with asthma. METHODS The study participants were 695 asthma patients, aged 20-44 years, from 29 medical centers in Japan. We excluded from the analysis of the result of the study 116 patients with complications of serious diseases, cough-variant asthma or aspirin-intolerant asthma. The patients completed the 8-Item Short-Form Health Survey (SF-8), the Airways Questionnaire 20 (AQ20), and the Japanese version of the Perceived Stress Scale (JPSS) and their doctors also provided clinical information including diagnosis, complications, severity of asthma, and results of pulmonary function and immunological tests. RESULTS There was a weak correlation between the generic quality of life (SF-8) and the disease-specific quality of life (AQ20). The AQ 20 revealed almost no association with the results of pulmonary function and immunological tests, and only a slight association with comorbidity of allergic rhinitis and food allergy. The AQ20 showed a moderate relation with perceived stress (JPSS) but a weak association with the severity of asthma. The multiple logistic models demonstrated that there was no relationship between the severity of asthma and the AQ20 in females, and in the age group of 20-34 years. CONCLUSIONS A major variable related to the disease-specific quality of life was perceived stress, followed by the severity of asthma. Stress management of patients with asthma may improve their quality of life.

Abstract
Mast cells are resident in the brain and contain numerous mediators, including neurotransmitters, cytokines, and chemokines, that are released in response to a variety of natural and pharmacological triggers. The number of mast cells in the brain fluctuates with stress and various behavioral and endocrine states. These properties suggest that mast cells are poised to influence neural systems underlying behavior. Using genetic and pharmacological loss-of-function models we performed a behavioral screen for arousal responses including emotionality, locomotor, and sensory components. We found that mast cell deficient Kit(W-sh/W-sh) (sash(-/-)) mice had a greater anxiety-like phenotype than WT and heterozygote littermate control animals in the open field arena and elevated plus maze. Second, we show that blockade of brain, but not peripheral, mast cell activation increased anxiety-like behavior. Taken together, the data implicate brain mast cells in the modulation of anxiety-like behavior and provide evidence for the behavioral importance of neuroimmune links.

Abstract
Recent research shows that exposure to community violence is, directly and indirectly, associated with asthma. This article reviews the findings on the impact of violence on asthma, and the pathways for the association of violence and asthma are suggested: 1) exposure to violence is directly associated with asthma, mainly through dysregulation of sympathetic-adrenal-medullary (SAM) and hypothalamic-pituitary-adrenal (HPA) axis, 2) exposure to violence is associated with the change of susceptibility of outdoor air pollution on asthma, probably through the change of an immune response, and 3) behavioral change due to exposure to violence (e.g. keeping children indoors) leads to more exposure to indoor pollutants. The suggested framework may be useful to develop health policy on asthma in high-violence communities.
