[CHARACTERISTICS OF THE SYMPTOMS DURING FOOD AND EXERCISE PROVOCATION TESTS IN PATIENTS AFTER ORAL IMMUNOTHERAPY: COMPARISON WITH FOOD-DEPENDENT EXERCISE-INDUCED ANAPHYLAXIS].

Objective: We aim to examine the characteristics of the symptoms induced by exercise provocation tests following allergen consumption in patients who have undergone oral immunotherapy (OIT).

Method: Patients who were positive for exercise provocation tests in Miyagi Children's Hospital from April 2012 to January 2019 were retrospectively analyzed. Patients were classified into food-dependent exerciseinduced anaphylaxis (FDEIA) group and post-OIT-FDEIA group.

Can Pediatricians Assess Exercise-Induced Bronchoconstriction From Post-exercise Videos?

Exercise-induced bronchoconstriction (EIB) is a highly prevalent morbidity of childhood asthma and defined by a transient narrowing of the airways during or after physical exercise. An exercise challenge test (ECT) is the reference standard for the diagnosis of EIB. Video evaluation of EIB symptoms could be a practical alternative for the assessment of EIB.

Exercise-induced bronchoconstriction in elite or endurance athletes:: Pathogenesis and diagnostic considerations.

Objective: To review the pathogenesis and evaluation of exercise-induced bronchoconstriction pertaining to the elite or endurance athlete, as well as propose a diagnostic algorithm based on the current literature.

Data Sources: Studies were identified using Ovid MEDLINE and reference lists of key articles.

Study Selections: Randomized controlled trials were selected when available.

Common Prescription Medications Used in Athletes.

Athletes of various skill levels commonly use many different types of medications, often at rates higher than the general population. Common medication classes used in athletes include analgesics such as nonsteroidal anti-inflammatory drugs and acetaminophen, inhalers for asthma and exercise-induced bronchoconstriction, antihypertensives, antibiotics, and insulin. Prescribers must be aware of the unique considerations for each of these medications when using them in patients participating in physical activity.

Special Considerations and Perspectives for Exercise-Induced Bronchoconstriction (EIB) in Olympic and Other Elite Athletes.

Diagnosing and treating elite and Olympic athletes with exercise-induced bronchoconstriction has been well established. However, a subset of elite and Olympic athletes with exercise-induced bronchoconstriction experience symptoms of breathlessness due to lack of adherence, improper medications, and/or generalized breathing dysfunction. A short review of traditional treatment plans for elite and Olympic athletes is presented along with the challenges of adherence, managing dysfunctional breathing, and measuring and treating mental skills deficits that may impact breathing.

Determinants of severe exercise-induced bronchoconstriction in Nigerian children with asthma.

Background/purpose: Asthmatics with severe exercise-induced bronchoconstriction (EIB) are at high risk of exacerbations. The purpose of this study was to determine the prevalence, phenotypic, and laboratory determinants of severe EIB in Nigerian children with asthma.

Methods: Children with controlled asthma (n = 101) underwent characterization and free-running exercise bronchoprovocation at a center in Nigeria.

Treadmill exercise restores memory and hippocampal synaptic plasticity impairments in ovalbumin-sensitized juvenile rats: Involvement of brain-derived neurotrophic factor (BDNF).

Studies demonstrate that asthma, especially during childhood, affects the functions of the brain including learning and memory. Exercise is well known for its neuroprotective functions and for its beneficial effects on asthma. We aimed to assess the effects of exercise on cognitive function, synaptic plasticity, and hippocampal brain-derived neurotrophic factor (BDNF) levels in ovalbumin (OVA) sensitized juvenile rats.

Association between regular exercise and asthma control among adults: The population-based Northern Finnish Asthma Study.

Previously those with asthma were often advised to avoid strenuous exercise because of fear for exercise-induced asthmatic reactions, but recent findings suggest many beneficial effects on health related to exercise. We elaborated on the relation between regular exercise and asthma control among adults. This was a population-based cross-sectional Northern Finnish Asthma Study (NoFAS), in which altogether 1922 adult subjects 17-73 years old living in Northern Finland answered the NoFAS questionnaire.

Impact of respiratory muscle training on respiratory muscle strength, respiratory function and quality of life in individuals with tetraplegia: a randomised clinical trial.

Background: Respiratory complications remain a leading cause of morbidity and mortality in people with acute and chronic tetraplegia. Respiratory muscle weakness following spinal cord injury-induced tetraplegia impairs lung function and the ability to cough. In particular, inspiratory muscle strength has been identified as the best predictor of the likelihood of developing pneumonia in individuals with tetraplegia.

Exercise-induced anaphylaxis: a case report and review of the literature.

Surgical intervention for exercise-induced laryngeal obstruction: A UK perspective.

Objectives: Exercise-induced laryngeal obstruction (EILO) is a prevalent cause of exertional breathlessness and wheeze in young individuals. Typically diagnosed using the continuous laryngoscopy during exercise (CLE) test, treatment is largely based on breathing retraining promoting improved laryngeal function. In some cases, these techniques fail to alleviate symptoms, and surgical intervention with supraglottoplasty can be valuable in the supraglottic form of EILO.

Dust mite ingestion-associated, exercise-induced anaphylaxis: a case report and literature review.

Background: Oral mite anaphylaxis (OMA) is a condition characterized by severe allergic reactions after ingesting food containing dust mite-contaminated flour. Physical exertion is recognized as a common trigger factor inducing anaphylaxis. The association of OMA with exercise-induced anaphylaxis has rarely been reported.

Exercise-Induced Bronchoconstriction in Iraq and Afghanistan Veterans With Deployment-Related Exposures.

Introduction: Acute exposure to high-levels of ambient fine particulate matter while exercising results in airway narrowing, but the long-term effects of repeated exposure on exercise-induced bronchoconstriction (EIB) are not well known. The goal of this preliminary study is to determine the rate of EIB among a sample of non-treatment seeking veterans deployed to Iraq and Afghanistan.

Materials And Methods: Twenty-four veterans (median [interquartile range]: 35.

Exercise-Induced Bronchoconstriction Identified Using the Forced Oscillation Technique.

Lung mechanics using the forced oscillation technique (FOT) is suggested to be equivalent and more sensitive in determining exercise-induced bronchoconstriction (EIB) than spirometry. Dynamic alterations in minute ventilation (V) may affect this measurement. We investigated changes in FOT parameters post exercise challenge (EC) in people with asthma as compared to spirometry.

Sex Differences in the Prevalence and Severity of Exercise-Induced Bronchoconstriction in Kindergarteners in Japan.

Background: Exercise-induced bronchoconstriction (EIB), a strong positive predictor of asthma, becomes progressively less frequent with age. Although asthma tends to become less common only in boys during adolescence, sex differences in EIB, especially in preschoolers, remain unclear. To find EIB for early diagnosis and intervention asthma, mass-screening tests considering sex differences in preschoolers are needed.

Tai Chi Chuan Exercise Improves Lung Function and Asthma Control through Immune Regulation in Childhood Asthma.

Background: Tai Chi Chuan (TCC) is an exercise of low to moderate intensity with key features of mindfulness, structural alignment, and flexibility to relax the body and mind in adults. Our previous study showed that TCC could improve the quality of life (QoL), pulmonary function, and fractional exhaled nitric oxide in asthmatic children. We further investigated whether the benefits induced by TCC were associated with immune regulation.

Effects of a heat and moisture exchanger on respiratory function and symptoms post-cold air exercise.

Purpose: Exercise at temperatures below -15°C induces drying and cooling of lung airways which causes exercise-induced bronchoconstriction (EIB) and respiratory symptoms, especially in winter sport athletes. The objective of this study was to evaluate whether a heat and moisture exchanger (HME) worn during intense cold air exercise improves lung function and reduces respiratory symptoms in healthy winter sport athletes.

Methods: Seven active males and six active females (maximum oxygen uptake 61.

Many continuous variables should be analyzed using the relative scale: a case study of β-agonists for preventing exercise-induced bronchoconstriction.

Background: The relative scale adjusts for baseline variability and therefore may lead to findings that can be generalized more widely. It is routinely used for the analysis of binary outcomes but only rarely for continuous outcomes. Our objective was to compare relative vs absolute scale pooled outcomes using data from a recently published Cochrane systematic review that reported only absolute effects of inhaled β-agonists on exercise-induced decline in forced-expiratory volumes in 1 s (FEV).

Controlled Delivery of 80 mg Aerosol Furosemide Does Not Achieve Consistent Dyspnea Relief in Patients.

Purpose: Aerosol furosemide may be an option to treat refractory dyspnea, though doses, methods of delivery, and outcomes have been variable. We hypothesized that controlled delivery of high dose aerosol furosemide would reduce variability of dyspnea relief in patients with underlying pulmonary disease.

Methods: Seventeen patients with chronic exertional dyspnea were recruited.

Clinical Characterization and Predictors of IOS-Defined Small-Airway Dysfunction in Asthma.

Background: The involvement of small airways has recently gained greater recognition in asthma. Impulse oscillometry (IOS) is a simple and noninvasive method based on the forced oscillation technique, for the detection of small-airway dysfunction (SAD).

Objective: To identify the predictors of SAD in an unselected sample of 400 patients with physician-diagnosed asthma.

Dehydration affects exercise-induced asthma and anaphylaxis.

Allergies are generally triggered by food, medication, physical exercise, stress, alcohol consumption, and dehydration. There are reports that indicate dehydration affects various kinds of physical allergies. However, there are few studies that have focused on the effects of dehydration on asthma and allergy anaphylaxis.
