Abstract
Panic disorder is a common psychiatric diagnosis characterized by acute, distressing somatic symptoms that mimic medically-relevant symptoms. As a result, individuals with panic disorder overutilize personal and healthcare resources in an attempt to diagnose and treat physical symptoms that are often medically benign. A biobehavioral perspective on these symptoms is needed that integrates psychological and medical knowledge to avoid costly treatments and prolonged suffering. This narrative review examines six common somatic symptoms of panic attacks (non-cardiac chest pain, palpitations, dyspnea, dizziness, abdominal distress, and paresthesia), identified in the literature as the most severe, prevalent, or critical for differential diagnosis in somatic illness, including long COVID. We review somatic illnesses that are commonly comorbid or produce panic-like symptoms, their relevant risk factors, characteristics that assist in distinguishing them from panic, and treatment approaches that are typical for these conditions. Additionally, this review discusses key factors, including cultural considerations, to assist healthcare professionals in differentiating benign from medically relevant symptoms in panic sufferers.

Abstract
RATIONALE Chronic obstructive pulmonary disease (COPD) is characterized by dysfunctional breathing patterns that contribute to impaired lung function and symptoms of dyspnea, anxiety, and abnormal carbon dioxide (CO2) levels. OBJECTIVE The study objective was to measure the acceptability of a new mind-body intervention we developed called Capnography-Assisted, Learned Monitored (CALM) Breathing, implemented before pulmonary rehabilitation. METHODS CALM Breathing is a 4-week (8-session) intervention designed to treat dyspnea and anxiety in adults with COPD by targeting dysfunctional breathing behaviors (guided by end-tidal CO2 levels). CALM Breathing consists of ten core breathing exercises, CO2 biofeedback, and motivational interviewing. Using qualitative methods and semi-structured interviews immediately post-intervention, we evaluated the acceptability and participation process of CALM Breathing. Themes were identified using constant comparative analysis. RESULTS Sixteen participants were interviewed after receiving CALM Breathing. Three main themes of CALM Breathing were identified: (1) Process of learning self-regulated breathing, (2) Mechanisms of a mind-body intervention, (3) Clinical and implementation outcomes. CONCLUSIONS Positive themes supported the acceptability of CALM Breathing and described participants' process of learning more self-regulated breathing to manage their dyspnea and anxiety. Positive signals from qualitative participant feedback provided support for CALM Breathing as an intervention for COPD, but larger scale efficacy trials are needed.

Abstract
BACKGROUND Although dyspnea is a primary symptom of chronic obstructive pulmonary disease (COPD), its treatment is suboptimal. In both COPD and acute anxiety, breathing patterns become dysregulated, contributing to abnormal CO2, dyspnea, and inefficient recovery from breathing challenges. While pulmonary rehabilitation (PR) improves dyspnea, only 1-2% of patients access it. Individuals with anxiety who use PR have worse outcomes. METHODS We present the protocol of a randomized controlled trial designed to determine the feasibility and acceptability of a new, four-week mind-body intervention that we developed, called "Capnography-Assisted Learned, Monitored (CALM) Breathing," as an adjunct to PR. Eligible participants are randomized in a 1:1 ratio to either CALM Breathing program or Usual Care. CALM Breathing consists of 10 core, slow breathing exercises combined with real time biofeedback (of end-tidal CO2, respiratory rate, and airflow) and motivational interviewing. CALM Breathing promotes self-regulated breathing, linking CO2 changes to dyspnea and anxiety symptoms and targeting breathing efficiency and self-efficacy in COPD. Participants are randomized to CALM Breathing or a Usual Care control group. RESULTS Primary outcomes include feasibility and acceptability metrics of recruitment efficiency, participant retention, intervention adherence and fidelity, PR facilitation, patient satisfaction, and favorable themes from interviews. Secondary outcomes include breathing biomarkers, symptoms, health-related quality of life, six-minute walk distance, lung function, mood, physical activity, and PR utilization and engagement. CONCLUSION By disrupting the cycle of dyspnea and anxiety, and providing a needed bridge to PR, CALM Breathing may address a substantive gap in healthcare and optimize treatment for patients with COPD.

Abstract
OBJECTIVE The review aims to determine the effect of breathing re-training on End-tidal carbon-di-oxide (ETCO2) in patients with asthma. DATA SOURCES A systematic search of articles was performed in PubMed, Cochrane, PEDro, Scopus, and Ovid databases from their inception till May 2022. STUDY SELECTIONS Studies were included if the patients were clinically diagnosed with mild-moderate asthma. Randomized controlled trials that monitored ETCO2 as a primary or secondary outcome were included. Studies were examined for potential risk of bias using the Revised Cochrane risk of bias tool by two independent reviewers. RESULTS Eight articles were included. The trials used various techniques like Buteyko, Papworth, Biofeedback, and holistic approach. Quantitative analysis was conducted to examine the effects on ETCO2 at various time points. A significant large effect was seen on ETCO2 following breathing re-training post-treatment, 3 and 6 months post-intervention. CONCLUSION There is moderate evidence for a significant effect of breathing re-training on ETCO2 in the short and long term in patients with asthma. However, high-quality randomized controlled trials using standardized measurement of ETCO2 are required to evaluate the effects of different breathing re-training techniques.

Abstract
The management of asthma has fundamentally changed during the past decades. The present guideline for the diagnosis and treatment of asthma was developed for respiratory specialists who need detailed and evidence-based information on the new diagnostic and therapeutic options in asthma. The guideline shows the new role of biomarkers, especially blood eosinophils and fractional exhaled NO (FeNO), in diagnostic algorithms of asthma. Of note, this guideline is the first worldwide to announce symptom prevention and asthma remission as the ultimate goals of asthma treatment, which can be achieved by using individually tailored, disease-modifying anti-asthmatic drugs such as inhaled steroids, allergen immunotherapy or biologics. In addition, the central role of the treatment of comorbidities is emphasized. Finally, the document addresses several challenges in asthma management, including asthma treatment during pregnancy, treatment of severe asthma or the diagnosis and treatment of work-related asthma.

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
Hyperventilation syndrome (HVS) is a frequent disorder of which the etiology is unclear. Diagnosis is based on the ruling out of organic disease and, more positively, on results of the Nijmegen questionnaire, reproduction of symptoms during the hyperventilation provocation test (HPVT), and detected hypocapnia. Treatment is based on targeted respiratory physiotherapy consisting in voluntary hypoventilation and instructions to the patient on regular respiratory exercise over an appreciable period of time. Additional research is needed to evaluate the validity of current investigative tools leading to the diagnosis of hyperventilation syndrome and to appraise the efficacy of current respiratory physiotherapy methods.

Abstract
A sigh is a distinct respiratory behavior with specific psychophysiological roles. In two accompanying reviews we will discuss the physiological and psychological functions of the sigh. The present review will focus on the psychological functions of the sigh. We discuss the regulatory effects of a sigh, and argue how these effects may become maladaptive when sighs occur excessively. The adaptive role of a sigh is discussed in the context of regulation of psychophysiological states. We propose that sighs facilitate transitions from one psychophysiological state to the next, and this way contribute to psychophysiological flexibility, via a hypothesized resetting mechanism. We discuss how a sigh resets respiration, by controlling mechanical and metabolic properties of respiration associated with respiratory symptoms. Next, we elaborate on a sigh resetting emotional states by facilitating emotional transitions. We attempt to explain the adaptive and maladaptive functions of a sigh in the framework of stochastic resonance, in which we propose occasional, spontaneous sighs to be noise contributing to psychophysiological regulation, while excessive sighs result in psychophysiological dysregulation. In this context, we discuss how sighs can contribute to therapeutic interventions, either by increasing sighs to improve regulation in case of a lack of sighing, or by decreasing sighs to restore regulation in case of excessive sighing. Finally, a research agenda on the psychology of sighs is presented.

Abstract
Breathing is a critical, complex, and highly integrated behavior. Normal rhythmic breathing, also referred to as eupnea, is interspersed with different breathing related behaviors. Sighing is one of such behaviors, essential for maintaining effective gas exchange by preventing the gradual collapse of alveoli in the lungs, known as atelectasis. Critical for the generation of both sighing and eupneic breathing is a region of the medulla known as the preBötzinger Complex (preBötC). Efforts are underway to identify the cellular pathways that link sighing as well as sneezing, yawning, and hiccupping with other brain regions to better understand how they are integrated and regulated in the context of other behaviors including chemosensation, olfaction, and cognition. Unraveling these interactions may provide important insights into the diverse roles of these behaviors in the initiation of arousal, stimulation of vigilance, and the relay of certain behavioral states. This chapter focuses primarily on the function of the sigh, how it is locally generated within the preBötC, and what the functional implications are for a potential link between sighing and cognitive regulation. Furthermore, we discuss recent insights gained into the pathways and mechanisms that control yawning, sneezing, and hiccupping.

Abstract
Dyspnoea self-management is often suboptimal for patients with COPD. Many patients with COPD experience chronic dyspnoea as distressing and disabling, especially during physical activities. Breathing therapy is a behavioural intervention that targets reducing the distress and impact of dyspnoea on exertion in daily living. Using a qualitative design, we conducted interviews with 14 patients after they participated in a novel mind-body breathing therapy intervention adjunct, capnography-assisted respiratory therapy (CART), combined with outpatient pulmonary rehabilitation. Comprehensive CART consisted of patient-centred biofeedback, tailored breathing exercises, a home exercise programme and motivational interviewing counselling. We assessed participants' perceptions and reported experiences to gauge the acceptability of CART and refine CART based on feedback. Constant comparative analysis was used to identify commonalities and themes. We identified three main themes relating to the acceptability and reported benefits of CART: (1) self-regulating breathing; (2) impact on health; and (3) patient satisfaction. Our findings were used to refine and optimise CART (i.e. its intensity, timing and format) for COPD. By addressing dysfunctional breathing behaviours and dysregulated interoception, CART offers a promising new paradigm for relieving dyspnoea and related anxiety in patients with COPD.

Abstract
BACKGROUND High normal resting pCO2 is a risk factor for salt sensitivity of blood pressure (BP) in normotensive humans and has been associated with higher resting systolic BP in postmenopausal women. To date, however, no known studies have investigated the effects of regular practice of voluntary mild hypocapnic breathing on BP in hypertensive patients. The objective of the present research was to test the hypothesis that capnometric feedback training can decrease both resting pCO2 and 24-h BP in a series of mildly hypertensive postmenopausal women. METHODS A small portable end tidal CO2 (etCO2) monitor was constructed and equipped with software that determined the difference between the momentary etCO2 and a pre-programmed criterion range. The monitor enabled auditory feedback for variations in CO2 outside the criterion range. 16 mildly hypertensive postmenopausal women were individually trained to sustain small decreases in etCO2 during six weekly sessions in the clinic and daily sessions at home. 24-h BP monitoring was conducted before and after the intervention, and in 16 prehypertensive postmenopausal women in a control group who did not engage in the capnometric training. RESULTS Following the intervention, all 16 capnometric training participants showed decreases in resting etCO2 (- 4.3 ± 0.4 mmHg; p < .01) while 15 showed decreases in 24-h systolic BP (- 7.6 ± 2.0 mmHg; p < .01). No significant changes in either measure was observed in the control group. In addition, nighttime (- 9.5 ± 2.6; p < .01) and daytime (- 6.7 ± 0.2 mmHg) systolic BP were both decreased following capnometric training, while no significant changes in nighttime (- 2.8 ± 2.2 mmHg; p = .11) or daytime (- 0.7 ± 1.0 mmHg; p ≤ .247) systolic BP were observed in the control group. CONCLUSIONS These findings support the hypothesis that regular practice of mild hypocapnic breathing that decreases resting etCO2 reliably decreases 24-h blood pressure in hypertensive postmenopausal women. The extent to which these effects persist beyond the training period or can be observed in other hypertensive subgroups remains to be investigated.

Cost-Effectiveness of Pulmonary Rehabilitation in Patients With Bronchial Asthma: An Analysis of the EPRA Randomized Controlled Trial.

[PMID: 34452704 DOI: 10.1016/j.jval.2021.01.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 11/26/2020] [Accepted: 01/15/2021] [Indexed: 06/13/2023]
Abstract
OBJECTIVES At 3 months after the intervention, this study evaluates the cost-effectiveness of a 3-week inpatient pulmonary rehabilitation (PR) in patients with asthma compared with usual care alongside the single-center randomized controlled trial-Effectiveness of Pulmonary Rehabilitation in Patients With Asthma. METHODS Adopting a societal perspective, direct medical costs and productivity loss were assessed using the Questionnaire for Health-Related Resource Use-Lung, a modification of the FIM in an Elderly Population. The effect side was operationalized as minimal important differences (MIDs) of the Asthma Control Test (ACT) and the Asthma Quality of Life Questionnaire (AQLQ) and through quality-adjusted life-years (QALYs) gained. Adjusted mean differences in costs (gamma-distributed model) and each effect parameter (Gaussian-distributed model) were simultaneously calculated within 1000 bootstrap replications to determine incremental cost-effectiveness ratios (ICERs) and to subsequently delineate cost-effectiveness acceptability curves. RESULTS PR caused mean costs per capita of €3544. Three months after PR, we observed higher mean costs (Δ€3673; 95% confidence interval (CI) €2854-€4783) and improved mean effects (ACT Δ1.59 MIDs, 95% CI 1.37-1.81; AQLQ Δ1.76 MIDs, 95% CI 1.46-2.08; QALYs gained Δ0.01, 95% CI 0.01-0.02) in the intervention group. The ICER was €2278 (95% CI €1653-€3181) per ACT-MID, €1983 (95% CI €1430-€2830) per AQLQ-MID, and €312 401 (95% CI €209 206-€504 562) per QALY gained. CONCLUSIONS Contrasting of PR expenditures with ICERs suggests that the intervention, which achieves clinically relevant changes in asthma-relevant parameters, has a high probability to be already cost-effective in the short term. However, in terms of QALYs, extended follow-up periods are likely required to comprehensively judge the added value of a one-time initial investment in PR.

Abstract
OBJECTIVE Asthma is frequently accompanied by dysfunctional breathing of which hyperventilation has been recognized as a subtype. The prevalence of hyperventilation in stable asthma has been scantily studied using blood gas analysis. Hence, a reliable estimate of its prevalence is lacking. It is unknown whether the Nijmegen Questionnaire (NQ) is a useful screening tool for hyperventilation in asthma. Therefore, the primary aim of this study was to determine the prevalence of hyperventilation in a large sample of patients with asthma in a stable state of disease. Secondary aims were to compare the clinical characteristics between patients with and without hyperventilation, and, to examine the concurrent validity of the NQ to detect hypocapnia in patients with asthma. METHODS A real-world, observational, multicenter study was conducted. Capillary blood gas analysis was performed in adults with a confirmed diagnosis of stable asthma. A subset of patients completed the NQ. RESULTS A blood gas analysis was obtained in 1006 patients. In 17% of the patients an acute hyperventilation was found, and in another 23% a chronic hyperventilation was uncovered. Patients with a chronic hyperventilation blood gas were more often female, were younger and had a better spirometric outcomes. The NQ appeared not to correlate with PCO2. CONCLUSION Hyperventilation is common in patients with stable asthma. Chronic hyperventilation is more often found in females of younger age and with the best spirometric outcomes compared to patients without hyperventilation. The NQ is not a suitable screening tool for the presence of hyperventilation in stable asthmatics.

Abstract
Heart rate variability (HRV) and end tidal CO2 (ETCO2) in relation to treatment response have not been studied in Latino populations or in comorbid asthma and panic disorder (PD). An extension of previously published research, the current study explored psychophysiological variables as possible mediators of treatment response. Latino treatment completers (N = 32) in the Bronx with asthma-PD received either Cognitive-Behavioral Psychophysiological Therapy (CBPT) or Music Relaxation Therapy (MRT). CBPT included HRV-biofeedback (HRVB); in-the-moment heart rate data to help an individual learn to influence his/her own heart rate. The sample was primarily female (93.8%) and Puerto Rican (81.25%). Treatment groups did not differ on demographics, except for less education in CBPT. The Panic Disorder Severity Scale (PDSS) and Asthma Control Questionnaire (ACQ) assessed changes in symptoms. HRV and ETCO2 were measured at four of eight therapy sessions. Baseline ETCO2 and changes in HRV from first to last of psychophysiology sessions were investigated as mediators of change on ACQ and PDSS. Mixed model analyses indicated in the CPBT group, changes in both asthma control and PD severity were not mediated by changes in HRV. In the CBPT and MRT groups combined, changes in PD severity were not mediated by baseline ETCO2. These findings may be due to the brevity of HRVB in CBPT, multiple treatment components, ETCO2 not directly targeted, and/or unique physiological pathways in Latinos with asthma-PD.

In-Patient Pulmonary Rehabilitation to Improve Asthma Control–A Randomized Controlled Study (EPRA, Effectiveness of Pulmonary Rehabilitation for Patients with Asthma). DEUTSCHES ARZTEBLATT INTERNATIONAL 2021; 118:23-30. [PMID: 33759752 PMCID: PMC8129066 DOI: 10.3238/arztebl.m2021.0003] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 12/23/2019] [Accepted: 05/28/2020] [Indexed: 12/18/2022]
Abstract
BACKGROUND Despite the availability of effective pharmaceutical treatment options, many patients with asthma do not manage to control their illness. This randomized trial with a waiting-list control group examined whether a 3-week course of inpatient pulmonary rehabilitation (PR) improves asthma control (primary endpoint) and other secondary endpoints (e.g., quality of life, cardinal symptoms, mental stress). The subsequent observational segment of the study investigated the long-term outcome after PR. METHODS After approval of the rehabilitation´ by the insurance providers (T0), 412 adults with uncontrolled asthma (Asthma Control Test [ACT] score < 20 points) undergoing rehabilitation were assigned to either the intervention group (IG) or the waiting-list control group (CG). PR commenced 1 month (T1) after randomization in the IG and 5 months after randomization (T3) in the CG. Asthma control and the secondary endpoints were assessed 3 months after PR in the IG (T3) as an intention-to-treat analysis by means of analyses of covariance. Moreover, both groups were observed for a period of 12 months after the end of PR. RESULTS At T3 the mean ACT score was 15.76 points in the CG, 20.38 points in the IG. The adjusted mean difference of 4.71 points was clinically relevant (95% confidence interval [3.99; 5.43]; effect size, Cohen's d = 1.27). The secondary endpoints also showed clinically relevant effects in favor of the IG. A year after the end of rehabilitation the mean ACT score was 19.00 points, still clinically relevant at 3.54 points higher than when rehabilitation began. Secondary endpoints such as quality of life and cardinal symptoms (dyspnea, cough, expectoration, pain) and self-management showed moderate to large effects. CONCLUSION The trial showed that a 3-week course of PR leads to clinically relevant improvement in asthma control and secondary endpoints. Patients who do not achieve control of their asthma despite outpatient treatment therefore benefit from rehabilitation.

Abstract
Nitric oxide is a gas produced in the airways of asthmatic subjects and related to T2 inflammation. It can be measured as fractional nitric oxide (FeNO) in the exhaled air and used as a non-invasive, easy to evaluate, rapid marker. It is now widely used in many settings to determine airway inflammation. The aim of this narrative review is to report relationship between FeNO and the physiopathologic characteristics of asthmatic patients. Factors affecting FeNO levels have also been analysed as well as the impact of corticosteroid, target therapies and rehabilitation programs. Considering the availability of the test, spreading this methodology to low income countries has also been considered as a possibility for evaluating airway inflammation and monitoring adherence to inhaled corticosteroid therapy. PubMed data search has been performed restricted to English language papers. Research was limited to studies in adults unless studies in children were the only ones reported for a particular issue. This revision could be useful to summarize the role of FeNO in relation to asthma characteristics and help in the use of FeNO in different clinical settings particularly in low income countries.

Abstract
BACKGROUND Evidence supports the Buteyko breathing technique (BBT) as reducing medication and improving control and quality of life in adults with asthma, but having minimal impact on spirometry. For children with asthma, evidence addressing the utility of BBT is sparse. We evaluated the effectiveness of BBT in managing various aspects of asthma in children. METHODS Thirty-two children with partly controlled asthma (age 6-15 years, 66% male) were randomized to either Treatment as Usual (TAU) or TAU combined with Buteyko training (Buteyko group, BG). Children in the BG received an intensive five-day training followed by three months of home practice. Primary outcome was bronchodilator reduction. Secondary outcomes were changes in physiological parameters FEV1_AR (at rest), FEV1_ER (after ergometry), FEV1_BR (after bronchospasmolysis), corticosteroid use, FeNO, SpO2, breath-hold test and questionnaire data [Asthma Control Questionnaire and Pediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ)]. All measures were collected at Baseline and a three-month follow-up. RESULTS For the primary outcome, no significant between-group difference was found. Regarding the secondary outcomes, children receiving treatment augmented with BBT revealed significantly greater improvement at the follow-up than those receiving TAU for FEV1_AR (p = .04, d=-0.50), FEV1_ER (p = .02, d=-0.52), and the emotional function subscale of the PACQLQ (p < .01, d = 1.03). No between-group differences were found for the remaining secondary measures of outcome. CONCLUSIONS Our preliminary findings suggest that the addition of BBT to treatment as usual for children with asthma enhances outcomes with respect to spirometry and parental emotional function but does not lead to reductions in medication, at least over the short term.

Abstract
BACKGROUND Aerobic training and breathing exercises are interventions that improve asthma control. However, the outcomes of these 2 interventions have not been compared. OBJECTIVE To compare the effects of aerobic training versus breathing exercises on clinical control (primary outcome), quality of life, exercise capacity, and airway inflammation in outpatients with moderate-to-severe asthma. METHODS Fifty-four asthmatics were randomized into either the aerobic training group (AG, n = 29) or the breathing exercise group (BG, n = 25). Both interventions lasted for 24 sessions (2/week, 40 minutes/session). Asthma clinical control (Asthma Control Questionnaire [ACQ]), quality of life (Asthma Quality of Life Questionnaire), asthma symptom-free days (ASFD), airway inflammation, exercise capacity, psychological distress (Hospital Anxiety and Depression Scale), daily-life physical activity (DLPA), and pulmonary function were evaluated before, immediately after, and 3 months after the intervention. RESULTS Both interventions presented similar results regarding the ACQ score, psychological distress, ASFD, DLPA, and airway inflammation (P > .05). However, participants in the AG were 2.6 times more likely to experience clinical improvement at the 3-month follow-up than participants in the BG (P = .02). A greater proportion of participants in the AG also presented a reduction in the number of days without rescue medication use compared with BG (34% vs 8%; P = .04). CONCLUSIONS Outpatients with moderate-to-severe asthma who participated in aerobic training or breathing exercise programs presented similar results in asthma control, quality of life, asthma symptoms, psychological distress, physical activity, and airway inflammation. However, a greater proportion of participants in the AG presented improvement in asthma control and reduced use of rescue medication.

Abstract
Breathing at a frequency of around 0.1 Hz is widely used in basic research and in applied psychophysiology because it strongly increases fluctuations in the cardiovascular system and affects psychological functioning. Volitional control of breathing often leads to hyperventilation among untrained individuals, which may produce aversive symptoms and alter the psychological and physiological effects of the paced breathing. The present study investigated the effectiveness of a brief anti-hyperventilation instruction during paced breathing at a frequency of 0.1 Hz. Forty-six participants were randomly assigned to one of two groups: a group given an anti-hyperventilation instruction and a control group without such an instruction. The instruction asked participants to avoid excessively deep breathing and to breathe shallowly and naturally. Participants performed the breathing task for 10 min. Hyperventilation was measured by partial pressure of end-tidal CO2 (PetCO2); furthermore, symptoms of hyperventilation, feeling of air hunger, task difficulty, and affective state were measured by self-report. The results showed that paced breathing without instruction decreased PetCO2 by 5.21 mmHg and that the use of the anti-hyperventilation instruction reduced the drop in PetCO2 to 2.7 mmHg. Symptoms of hyperventilation were lower in the group with the anti-hyperventilation instruction. Neither the feeling of air hunger nor task difficulty were affected by the instruction. There were no significant effects of the instruction on affective state. The present study indicates that a brief anti-hyperventilation instruction may be used to decrease drop in PetCO2 and symptoms of hyperventilation during breathing at 0.1 Hz and that the instruction is well tolerated.

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).

[PMID: 31220170 PMCID: PMC6586331 DOI: 10.1371/journal.pone.0218550] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2019] [Accepted: 06/04/2019] [Indexed: 01/27/2023] Open
Abstract
Volitional control of breathing often leads to excessive ventilation (hyperventilation) among untrained individuals, which disrupts CO2 homeostasis and may elicit a set of undesirable symptoms. The present study investigated whether seven days of training without any anti-hyperventilation instructions improves CO2 homeostasis during paced breathing at a frequency of 0.1 Hz (6 breaths/minute). Furthermore, the present study investigated the effects of training on breathing-related changes in affective state to examine the hypothesis that training improves the influence of slow paced breathing on affect. A total of 16 participants performed ten minutes of paced breathing every day for seven days. Partial pressure of end-tidal CO2 (PetCO2), symptoms of hyperventilation, affective state (before and after breathing), and pleasantness of the task were measured on the first, fourth, and seventh days of training. Results showed that the drop in PetCO2 significantly decreased with training and none of the participants experienced a drop in PetCO2 below 30 mmHg by day seven of training (except one participant who already had PetCO2 below 30 mmHg during baseline), in comparison to 37.5% of participants on the first day. Paced breathing produced hyperventilation symptoms of mild intensity which did not decrease with training. This suggests that some participants still experienced a drop of PetCO2 that was deep enough to produce noticeable symptoms. Affective state was shifted towards calmness and relaxation during the second and third laboratory measurements, but not during the first measurement. Additionally, the breathing task was perceived as more pleasant during subsequent laboratory measurements. The obtained results showed that training paced breathing at 0.1 Hz led to decrease in hyperventilation. Furthermore, the present study suggests that training paced breathing is necessary to make the task more pleasant and relaxing.

Abstract
Smoking cessation remains a major issue for asthmatic smokers. Respiratory rehabilitation and respiratory physiotherapy have shown a benefit in controlling symptoms, preventing exacerbations and improving the quality of life. The control of the environment is crucial and must be approached in a global way. Management of obesity and psychological disorders should be systematically proposed. Allergen immunotherapy may be discussed in allergic persistent asthma to house dust mites. Certain dietary interventions or alternative medicines have not proved their worth.

Effects of respiratory and applied muscle tensing interventions on responses to a simulated blood draw among individuals with high needle fear. J Behav Med 2018; 41:771-783.

Abstract
Fear of blood and needles increases risk for presyncopal symptoms. Applied muscle tension can prevent or attenuate presyncopal symptoms; however, it is not universally effective. This study examined the effects of applied muscle tension, a respiratory intervention, and a no treatment control condition, on presyncopal symptoms and cerebral oxygenation, during a simulated blood draw with individuals highly fearful of needles. Participants (n = 95) completed questionnaires, physiological monitoring, and two trials of a simulated blood draw with recovery. Presyncopal symptoms decreased across trials; however, no group differences emerged. Applied muscle tension was associated with greater cerebral oxygenation during trial two, and greater end-tidal carbon dioxide during both trials. The respiratory intervention did not differ from the no treatment control. Applied muscle tension is an intervention that can increase cerebral oxygenation and end-tidal carbon dioxide. While the respiratory intervention is promising within therapeutic settings, it was not efficacious after a brief audio training.

Hypoventilation Therapy Alleviates Panic by Repeated Induction of Dyspnea. BIOLOGICAL PSYCHIATRY: COGNITIVE NEUROSCIENCE AND NEUROIMAGING 2018; 3:539-545. [PMID: 29573981 DOI: 10.1016/j.bpsc.2018.01.010] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2017] [Revised: 01/03/2018] [Accepted: 01/05/2018] [Indexed: 01/03/2023]
Abstract
BACKGROUND Previous research has shown that hypoventilation therapy reduces panic symptoms in part by increasing basal partial pressure of carbon dioxide (PCO2) levels. We tested an additional pathway by which hypoventilation therapy could exert its therapeutic effects: through repeated interoceptive exposure to sensations of dyspnea. METHODS A total of 35 patients with panic disorder were trained to perform exercises to raise their end-tidal PCO2 levels using a portable capnometry device. Anxiety, dyspnea, end-tidal PCO2, and respiratory rate were assessed during each exercise across 4 weeks of training. Mixed-model analysis examined whether within-exercise levels of dyspnea were predictive of reduction of panicogenic cognitions. RESULTS As expected, within-exercise anxiety and respiratory rate decreased over time. Unexpectedly, PCO2 dropped significantly from the beginning to the end of exercise, with these drops becoming progressively smaller across weeks. Dyspnea increased and remained consistently above basal levels across weeks. As hypothesized, greater dyspnea was related to significantly lower panicogenic cognitions over time even after controlling for anxiety and PCO2. Additional exploratory analyses showed that within-exercise increases in dyspnea were related to within-exercise increases in anxiety but were not related to within-exercise increases in PCO2. CONCLUSIONS In support of the interoceptive exposure model, we found that greater dyspnea during hypoventilation exercises resulted in lower panicogenic cognitions even after the effect of PCO2 was taken into account. The findings offer an additional important target in panic treatment.

Courtney R. Breathing training for dysfunctional breathing in asthma: taking a multidimensional approach. ERJ Open Res 2017; 3:00065-2017.

Abstract
Various breathing training programmes may be helpful for adults with asthma. The main therapeutic aim for many of these programmes is the correction of dysfunctional breathing. Dysfunctional breathing can be viewed practically as a multidimensional entity with the three key dimensions being biochemical, biomechanical and psychophysiological. The objectives of this review are to explore how each of these dimensions might impact on asthma sufferers, to review how various breathing therapy protocols target these dimensions and to determine if there is evidence suggesting how breathing therapy protocols might be optimised. Databases and reference lists of articles were searched for peer-reviewed English language studies that discussed asthma or dysfunctional breathing and various breathing therapies. Biochemical, biomechanical and psychophysiological aspects of dysfunctional breathing can all potentially impact on asthma symptoms and breathing control. There is significant variation in breathing training protocols and the extent to which they evaluate and improve function in these three dimensions. The various dimensions of dysfunctional breathing may be of greater or lesser importance in different cases and the effectiveness of breathing training protocols is likely to be improved when all three dimensions are considered. Outcomes for breathing training for dysfunctional breathing in asthma may be most successful when the three key dimensions of dysfunctional breathing are evaluated at the start of treatment and monitored during treatment. This allows breathing training protocols to be adjusted as appropriate to ensure that treatment is sufficiently comprehensive and intensive to produce measurable improvements where necessary.

Abstract
BACKGROUND Blood injection injury (BII) phobia is common, with debilitating consequences to the health and well being of many of its sufferers. BII phobia presents with a unique fear response that can involve drops in blood pressure and ultimately fainting. The aim of this study was to provide proof of concept for a line of brief, easy to implement, video-based interventions for reducing phobic avoidance and fears in BII sufferers. One of the interventions was a novel Hypoventilation Respiratory Training (HRT) aimed at reducing the exaggerated ventilation response (hyperventilation) seen in BII phobia. The response has been linked to cerebral vasoconstriction and fainting symptoms. METHOD Sixty BII patients were randomly assigned to one of three 12-min video-guided trainings: Symptom-Associated Tension (SAT) training, Relaxation Skills Training (RST), or HRT. Experiential and cardiorespiratory activity to phobic stimuli was assessed before and after training. RESULTS Both SAT and HRT resulted in overall greater reductions of phobic fears and symptoms than RST. SAT significantly increased heart rate during exposure, and HRT led to significantly reduced ventilation, increases in PCO2 , and elevated blood pressure throughout exposure and recovery. Treatment expectancy was rated equally high across conditions, whereas credibility ratings were highest for HRT. CONCLUSIONS Brief, video-based instructions in muscle tension and normocapnic breathing are effective in reducing BII symptom severity and require minimal time and expertise. HRT may be particularly helpful in reducing fainting caused by cerebral vasoconstriction.

Abstract
Breathing retraining (BR) improves symptoms, psychological well-being and quality of life in adults with asthma; but there remains uncertainty as to mechanism of effect. One of the intuitively logical theories is that BR works through altering breathing pattern. There is currently no evidence, however, that BR does result in measurable changes in breathing pattern. In this case report we describe the effects of physiotherapy BR on a 57-year-old female with a 10-year history of asthma. Data were collected before and after a physiotherapy BR program comprising three sessions over 18 weeks: breathing pattern (respiratory inductive plethysmography (RIP); physiology (end tidal carbon dioxide (ETCO2), heart rate, oxygen saturations, spirometric lung function); questionnaires (Asthma Control Questionnaire (ACQ), Hospital Anxiety and Depression Score, Nijmegen Questionnaire); and medication usage. After BR, the patient's symptoms improved. Her physiology was largely unchanged, although her FEV1 increased by 0.12L, peak flow by 21L/min. The patient reported using less Salbutamol, yet her asthma control improved (ACQ down 1.5). Her Nijmegen score dropped from positive to negative for hyperventilation (from 39 to 7). Her anxiety-depression levels both reduced into 'normal' ranges. The patient's expiratory time increased, with longer respiratory cycles and slower respiratory rate. No changes were seen in relative contributions of ribcage and abdomen. Controlled trials are now needed to determine the generalizability of these findings.

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
Confusion between panic and asthma symptoms can result in serious self-management errors. A cognitive behavior psychophysiological therapy (CBPT) intervention was culturally adapted for Latinos consisting of CBT for panic disorder (PD), asthma education, differentiation between panic and asthma symptoms, and heart rate variability biofeedback. An RCT compared CBPT to music and relaxation therapy (MRT), which included listening to relaxing music and paced breathing at resting respiration rates. Fifty-three Latino (primarily Puerto Rican) adults with asthma and PD were randomly assigned to CBPT or MRT for 8 weekly sessions. Both groups showed improvements in PD severity, asthma control, and several other anxiety and asthma outcome measures from baseline to post-treatment and 3-month follow-up. CBPT showed an advantage over MRT for improvement in adherence to inhaled corticosteroids. Improvements in PD severity were mediated by anxiety sensitivity in CBPT and by depression in MRT, although earlier levels of these mediators did not predict subsequent improvements. Attrition was high (40%) in both groups, albeit comparable to CBT studies targeting anxiety in Latinos. Additional strategies are needed to improve retention in this high-risk population. Both CBPT and MRT may be efficacious interventions for comorbid asthma-PD, and CBPT may offer additional benefits for improving medication adherence.

Abstract
Asthma is a common long-term condition that remains poorly controlled in many people despite the availability of pharmacological interventions, evidence-based treatment guidelines and care pathways.(1) There is considerable public interest in the use of non-pharmacological approaches for the treatment of asthma.(2) A survey of people with asthma reported that many have used complementary and alternative medicine, often without the knowledge of their clinical team.(3) Such interventions include breathing techniques, herbal products, homeopathy and acupuncture. The role of breathing exercises within the management of asthma has been controversial, partly because early claims of effectiveness were exaggerated.(4) UK national guidance and international guidelines on the management of asthma have included the option of breathing exercise programmes as an adjuvant to pharmacological treatment.(5,6) Here we discuss the types of breathing exercises used and review the evidence for their effectiveness.

Abstract
OBJECTIVES Breathing exercises are used by some asthmatic patients, yet are often difficult to perform and time-consuming. This study evaluated a simple, modified breathing exercise program regarding ease to perform and effectiveness as an adjunctive therapy. METHODS Subjects age 18 to 65 with a current diagnosis of persistent asthma were enrolled. A program that incorporated three different breathing exercises (yoga pranayama techniques, diaphragmatic breathing and pursed lip breathing) was taught to subjects. The program was designed to be completed in less than 10 minutes per day. Subjects completed the Asthma Control Test (ACT) and mini-Asthma Quality of Life Questionnaire (AQLQ) at baseline and at 1-month follow-up. They also completed a survey that asked them to rate the effectiveness and difficulty of the exercises, and whether they would recommend them in the future. RESULTS A total of 74 subjects were enrolled in this study. The intervention improved breathing for 52.9% of the subjects, while 67.6% felt that their daily activity was improved and 66.1% noted that the exercises allowed decreased use of a rescue inhaler. Most subjects (80.9%) recommended breathing exercises as a complementary therapy for asthma and 79.4% of the subjects stated the exercises took less than 10 minutes per day total. Overall, ACT scores improved significantly (p = 0.002) with a statistically non-significant improvement in AQLQ scores. CONCLUSION A simple program of breathing exercises was found to be effective and could be completed in less than 10 minutes per day. Furthermore, there was a statistically significant improvement in ACT scores post-exercise.
