    Small airways dysfunction (SAD) contributes to the clinical expression of asthma. The identification of patients who suffer from SAD is important from a clinical perspective, as targeted therapy may improve patients' well-being and treatment efficacy. We aimed to realize the first step in the development of a simple small airways dysfunction tool (SADT) that may help to identify asthma patients having SAD. Asthma patients with and without SAD were interviewed. Patients were selected to participate in this study based on FEF50% and R5-R20 values from spirometry and impulse oscillometry respectively. Ten in depth interviews and two focus groups revealed that patients with and without SAD perceived differences in symptoms and signs, habits and health related issues. For example, patients with SAD reported to wheeze easily, were unable to breathe in deeply, mentioned more symptoms related to bronchial hyperresponsiveness, experienced more pronounced exercise-induced symptoms and more frequently had allergic respiratory symptoms after exposure to cats and birds. Based on these differences, 63 items were retained to be further explored for the SADT. The first step of the development of the SADT tool shows that there are relevant differences in signs and respiratory symptoms between asthma patients with and without SAD. The next step is to test and validate all items in order to retain the most relevant items to create a short and simple tool, which should be useful to identify asthma patients with SAD in clinical practice.

    Esophageal hemorrage due to variceal bleeding in cirrhotic patients represents a serious problem for the physician in charge, especially in this country where liver transplants are inexistent; and also, it is a drama for the patient and its familly. We propose here the Transjugular Intrahepatic Portosystemic Shunt (TIPS). Twenty one patients were part of a study where 23 TIPS were placed, observing an immediate improval in 18 of them, a rebleeding in 2, within the first 24 and 48 hours. An embolization of the coronary veins was performed in the procedure in 15 patients, and a second intervention due to rebleeding in 2 of them. In the latter patients, the embolization of the coronary veins was rutinary.The survival of the patients has been outstanding.We conclude that this interventional procedure is a worldwide reality in the treatment of esophageal hemorrage by variceal bleeding due to portal hipertension, and it does not cut down the probability of liver transplant, unfortunately inexistent in our country. This procedure results in a low morbimortality with an adequate quality of life.

    Full Text Available Abstract Asthma is the most common respiratory disorder in Canada. Despite significant improvement in the diagnosis and management of this disorder, the majority of Canadians with asthma remain poorly controlled. In most patients, however, control can be achieved through the use of avoidance measures and appropriate pharmacological interventions. Inhaled corticosteroids (ICSs represent the standard of care for the majority of patients. Combination ICS/long-acting beta2-agonists (LABA inhalers are preferred for most adults who fail to achieve control with ICS therapy. Allergen-specific immunotherapy represents a potentially disease-modifying therapy for many patients with asthma, but should only be prescribed by physicians with appropriate training in allergy. Regular monitoring of asthma control, adherence to therapy and inhaler technique are also essential components of asthma management. This article provides a review of current literature and guidelines for the appropriate diagnosis and management of asthma.

    It is well recognized that atopic sensitization is an important risk factor for asthma, both in adults and in children. However, the role of allergy in severe asthma is still under debate. The term 'Severe Asthma' encompasses a highly heterogeneous group of patients who require treatment on steps 4-5 of GINA guidelines to prevent their asthma from becoming 'uncontrolled', or whose disease remains 'uncontrolled' despite this therapy. Epidemiological studies on emergency room visits and hospital admissions for asthma suggest the important role of allergy in asthma exacerbations. In addition, allergic asthma in childhood is often associated with severe asthma in adulthood. A strong association exists between asthma exacerbations and respiratory viral infections, and interaction between viruses and allergy further increases the risk of asthma exacerbations. Furthermore, fungal allergy has been shown to play an important role in severe asthma. Other contributing factors include smoking, pollution and work-related exposures. The 'Allergy and Asthma Severity' EAACI Task Force examined the current evidence and produced this position document on the role of allergy in severe asthma. © 2016 John Wiley & Sons A/S.

  17. Diagnostic challenges of childhood asthma.

    Science.gov (United States)

    Bakirtas, Arzu

    2017-01-01

    Diagnosis of asthma in childhood is challenging. Both underdiagnosis and overdiagnosis of asthma are important issues. The present review gives information about challenging factors for an accurate diagnosis of childhood asthma. Although underdiagnosis of asthma in childhood has always been the most important diagnostic problem, overdiagnosis of asthma has also been increasingly recognized. This is probably due to diagnosis of asthma based on symptoms and signs alone. Demonstration of variable airflow obstruction by lung function tests is the most common asthma diagnostic tests used in practice and is therefore strongly recommended in children who can cooperate. Recently, an asthma guideline combining the clinical and economic evidences with sensitivity and specificity of diagnostic procedures was developed to improve accuracy of diagnosis and to avoid overdiagnosis. This guideline provided an algorithmic clinical and cost-effective approach and included fractional exhaled nitric oxide measurement as one of the diagnostic tests in addition to lung function. Diagnosis of asthma in children should be made by combining relevant history with at least two confirmatory diagnostic tests whenever possible. Diagnosis based on short-period treatment trials should be limited to young children who are unable to cooperate with these tests.

  11. Recent developments regarding periostin in bronchial asthma

    Directory of Open Access Journals (Sweden)

    Kenji Izuhara

    2015-09-01

    Full Text Available Although it is currently recognized that bronchial asthma is not a single disease but a syndrome, we have not yet made use of our new understanding of this heterogeneity as we treat asthma patients. To increase the efficacy of anti-asthma drugs and to decrease costs, it is important to stratify asthma patients into subgroups and to develop therapeutic strategies for each subgroup. Periostin has recently emerged as a biomarker for bronchial asthma, unique in that it is useful not in diagnosis but in categorizing asthma patients. We first found that periostin is a novel component of subepithelial fibrosis in bronchial asthma downstream of IL-13 signals. Thereafter, it was shown that periostin can be a surrogate biomarker of type 2 immune responses, the basis of the notion that a detection system of serum periostin is potentially a companion diagnostic for type 2 antagonists. Furthermore, we have recently shown that serum periostin can predict resistance or hyporesponsiveness to inhaled corticosteroids, based on its contribution to tissue remodeling or fibrosis in bronchial asthma. Thus, serum periostin has two characteristics as a biomarker for bronchial asthma: it is both a surrogate biomarker of type 2 immune responses and a biomarker reflecting tissue remodeling or fibrosis. We can take advantage of these characteristics to develop stratified medicine in bronchial asthma.

    2012-02-01

    The aim of this review is to underline the need for an adequate clinical and functional evaluation of respiratory function and asthma control in patients undergoing surgical procedures requiring general anesthesia to obtain useful information for an adequate preoperative pharmacological approach. It has been shown that baseline uncontrolled clinical/functional conditions of airways represent the most important risk factors for perioperative bronchospasm. In nonemergency conditions, asthma patients should undergo clinical/functional assessment at least 1 week before the surgery intervention to obtain, the better feasible control of asthma symptoms in the single patient. Some simple preoperative information given by the patient in preoperative consultation may be sufficient to identify individuals with uncontrolled or poor controlled asthmatic conditions. Spirometric evaluation is essential in individuals with poor control of symptoms, as well as in those patients with uncertain anamnestic data or limited perception of respiratory symptoms, and in those requiring lung resection. A better control of asthma must be considered the 'gold standard' for a patient at 'a reasonable low risk' to develop perioperative/postoperative bronchospasm. International consensus promoted by pulmonologists, anesthesiologists, and allergists might be useful to define a better diagnostic and therapeutic approach.

    Full Text Available Asthma is a chronic, reversible obstructive disease that when in exacerbation can present to the emergency department in a spectrum of severity. Prompt recognition of the potentially severely ill asthmatic requires a careful history and physical exam while considering alternative diagnoses for the presenting symptoms. Early administration of salbutamol and corticosteroids is indicated in almost all patients with other medications such as ipratropium and magnesium and supportive modalities like BiPAP reserved for sicker patients. The global impact of asthma is increasing, especially amongst children. While the benign clinical presentation is most common and mortality has decreased in recent decades due to improved recognition and care, the ubiquity of the condition and frequent lack of regular outpatient management contribute to the disease claiming 250,000 lives worldwide annually. The emergency physician must be prepared to assess and appropriately manage both the young child with a mild wheeze and the adult in respiratory failure.

  18. Virus-induced exacerbations in asthma and COPD

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available Chronic obstructive pulmonary disease (COPD is characterized by chronic airway inflammation and/or airflow limitation due to pulmonary emphysema. Chronic bronchitis, pulmonary emphysema, and bronchial asthma may all be associated with airflow limitation; therefore, exacerbation of asthma may be associated with the pathophysiology of COPD. Furthermore, recent studies have suggested that the exacerbation of asthma, namely virus-induced asthma, may be associated with a wide variety of respiratory viruses.COPD and asthma have different underlying pathophysiological processes and thus require individual therapies. Exacerbation of both COPD and asthma, which are basically defined and diagnosed by clinical symptoms, is associated with a rapid decline in lung function and increased mortality. Similar pathogens, including human rhinovirus, respiratory syncytial virus, influenza virus, parainfluenza virus and coronavirus, are also frequently detected during exacerbation of asthma and/or COPD. Immune response to respiratory viral infections, which may be related to the severity of exacerbation in each disease, varies in patients with both COPD and asthma. In this regard, it is crucial to recognize and understand both the similarities and differences of clinical features in patients with COPD and/or asthma associated with respiratory viral infections, especially in the exacerbative stage.In relation to definition, epidemiology, and pathophysiology, this review aims to summarize current knowledge concerning exacerbation of both COPD and asthma by focusing on the clinical significance of associated respiratory virus infections.

    2018-07-01

    We report here an unexpectedly robust ability of healthy human individuals ( n = 40) to recognize extremely distorted needle-like facial images, challenging the well-entrenched notion that veridical spatial configuration is necessary for extracting facial identity. In face identification tasks of parametrically compressed internal and external features, we found that the sum of performances on each cue falls significantly short of performance on full faces, despite the equal visual information available from both measures (with full faces essentially being a superposition of internal and external features). We hypothesize that this large deficit stems from the use of positional information about how the internal features are positioned relative to the external features. To test this, we systematically changed the relations between internal and external features and found preferential encoding of vertical but not horizontal spatial relationships in facial representations ( n = 20). Finally, we employ magnetoencephalography imaging ( n = 20) to demonstrate a close mapping between the behavioral psychometric curve and the amplitude of the M250 face familiarity, but not M170 face-sensitive evoked response field component, providing evidence that the M250 can be modulated by faces that are perceptually identifiable, irrespective of extreme distortions to the face's veridical configuration. We theorize that the tolerance to compressive distortions has evolved from the need to recognize faces across varying viewpoints. Our findings help clarify the important, but poorly defined, concept of facial configuration and also enable an association between behavioral performance and previously reported neural correlates of face perception.

  11. Viral asthma: implications for clinical practice

    Directory of Open Access Journals (Sweden)

    Roger Menendez

    2010-07-01

    Full Text Available Roger Menendez1, Michael D Goldman21Allergy and Asthma Center of El Paso, El Paso, TX, USA; 2Pulmonary Division, UCLA Gaffen School of Medicine, Los Angeles, CA, USAAbstract: The natural history of asthma appears to be driven primarily by the timing and duration of viral respiratory infections. From the very high rate of infections in childhood, to the more sporadic pattern seen in adults, the cycle of acute injury followed by an inefficient repair process helps explain the clinical patterns of asthma severity currently recognized by asthma guidelines. Why the asthmatic host responds to viral injury in a particular way is largely a mystery and the subject of intense investigation. The role of viruses in asthma extends not just to intermittent but to persistent disease, and to both the atopic as well as nonatopic phenotypes. Future therapeutic strategies should include primary prevention via the development of antiviral innate immunity-enhancing vaccines, as well as secondary prevention via the use of antiviral agents, or immunomodulators designed to boost the antiviral response or interrupt the proinflammatory cascade.Keywords: asthma, rhinoviruses, exacerbations, epidemiology, phenotypes, clinical trials

  19. The role of the primary care physician in helping adolescent and adult patients improve asthma control.

    Science.gov (United States)

    Yawn, Barbara P

    2011-09-01

    Many adolescents and adults with asthma continue to have poorly controlled disease, often attributable to poor adherence to asthma therapy. Failure to adhere to recommended treatment may result from a desire to avoid regular reliance on medications, inappropriate high tolerance of asthma symptoms, failure to perceive the chronic nature of asthma, and poor inhaler technique. Primary care physicians need to find opportunities and methods to address these and other issues related to poor asthma control. Few adolescents or adults with asthma currently have asthma "checkup" visits, usually seeking medical care only with an exacerbation. Therefore, nonrespiratory-related office visits represent an important opportunity to assess baseline asthma control and the factors that most commonly lead to poor control. Tools such as the Asthma Control Test, the Asthma Therapy Assessment Questionnaire, the Asthma Control Questionnaire, and the Asthma APGAR provide standardized, patient-friendly ways to capture necessary asthma information. For uncontrolled asthma, physicians can refer to the stepwise approach in the 2007 National Asthma Education and Prevention Program guidelines to adjust medication use, but they must consider step-up decisions in the context of quality of the patient's inhaler technique, adherence, and ability to recognize and avoid or eliminate triggers. For this review, a literature search of PubMed from 2000 through August 31, 2010, was performed using the following terms (or a combination of these terms): asthma, asthma control, primary care, NAEPP guidelines, assessment, uncontrolled asthma, burden, impact, assessment tools, triggers, pharmacotherapy, safety. Studies were limited to human studies published in English. Articles were also identified by a manual search of bibliographies from retrieved articles and from article archives of the author.

  20. How legumes recognize rhizobia.

    Science.gov (United States)

    Via, Virginia Dalla; Zanetti, María Eugenia; Blanco, Flavio

    2016-01-01

    Legume plants have developed the capacity to establish symbiotic interactions with soil bacteria (known as rhizobia) that can convert N2 to molecular forms that are incorporated into the plant metabolism. The first step of this relationship is the recognition of bacteria by the plant, which allows to distinguish potentially harmful species from symbiotic partners. The main molecular determinant of this symbiotic interaction is the Nod Factor, a diffusible lipochitooligosaccharide molecule produced by rhizobia and perceived by LysM receptor kinases; however, other important molecules involved in the specific recognition have emerged over the years. Secreted exopolysaccharides and the lipopolysaccharides present in the bacterial cell wall have been proposed to act as signaling molecules, triggering the expression of specific genes related to the symbiotic process. In this review we will briefly discuss how transcriptomic analysis are helping to understand how multiple signaling pathways, triggered by the perception of different molecules produced by rhizobia, control the genetic programs of root nodule organogenesis and bacterial infection. This knowledge can help to understand how legumes have evolved to recognize and establish complex ecological relationships with particular species and strains of rhizobia, adjusting gene expression in response to identity determinants of bacteria.

  1. Recognize and classify pneumoconiosis

    International Nuclear Information System (INIS)

    Hering, K.G.; Hofmann-Preiss, K.

    2014-01-01

    In the year 2012, out of the 10 most frequently recognized occupational diseases 6 were forms of pneumoconiosis. With respect to healthcare and economic aspects, silicosis and asbestos-associated diseases are of foremost importance. The latter are to be found everywhere and are not restricted to large industrial areas. Radiology has a central role in the diagnosis and evaluation of occupational lung disorders. In cases of known exposure mainly to asbestos and quartz, the diagnosis of pneumoconiosis, with few exceptions will be established primarily by the radiological findings. As these disorders are asymptomatic for a long time they are quite often detected as incidental findings in examinations for other reasons. Therefore, radiologists have to be familiar with the pattern of findings of the most frequent forms of pneumoconiosis and the differential diagnoses. For reasons of equal treatment of the insured a quality-based, standardized performance, documentation and evaluation of radiological examinations is required in preventive procedures and evaluations. Above all, a standardized low-dose protocol has to be used in computed tomography (CT) examinations, although individualized concerning the dose, in order to keep radiation exposure as low as possible for the patient. The International Labour Office (ILO) classification for the coding of chest X-rays and the international classification of occupational and environmental respiratory diseases (ICOERD) classification used since 2004 for CT examinations meet the requirements of the insured and the occupational insurance associations as a means of reproducible and comparable data for decision-making.

  2. Asthma as a disruption in iron homeostasis | Science ...

    Science.gov (United States)

    Over several decades, asthma has evolved from being recognized as a single disease to include a diverse group of phenotypes with dissimilar natural histories, pathophysiologies, responses to treatment, and distinctive molecular pathways. With the application of Occam’s razor to asthma, it is proposed that there is one cause underlying the numerous phenotypes of this disease and that the responsible molecular pathway is a deficiency of iron in the lung tissues. This deficiency can be either absolute (e.g. asthma in the neonate and during both pregnancy and menstruation) or functional (e.g. asthma associated with infections, smoking, and obesity). Comparable associations between asthma co-morbidity (e.g. eczema, urticaria, restless leg syndrome, and pulmonary hypertension) with iron deficiency support such a shared mechanistic pathway. Therapies directed at asthma demonstrate a capacity to impact iron homeostasis, further strengthening the relationship. Finally, pathophysiologic events producing asthma, including inflammation, increases in Th2 cells, and muscle contraction, can correlate with iron availability. Recognition of a potential association between asthma and an absolute and/or functional iron deficiency suggests specific therapeutic interventions including inhaled iron. Asthma is a public health issue that has environmental triggers. Iron homeostasis is an essential mechanism whereby the body manages the impact of environmental agents on overall

    Gupta, Atul; Bush, Andrew; Hawrylowicz, Catherine; Saglani, Sejal

    2012-12-01

    Vitamin D deficiency and insufficiency are increasingly being recognized in the general population, and have been largely attributed to lifestyle changes (reduced exposure to sunshine due to working indoors or the use of protective clothing and sunscreen; changes in diet) over the last few decades. The musculoskeletal consequences of severe vitamin D deficiency are well established, however, a number of other disorders have now been linked to vitamin D insufficiency, including asthma. There is growing appreciation of the likely importance of vitamin D as a pleiotrophic mediator that contributes to pulmonary health. Children with asthma appear to be at increased risk of vitamin D insufficiency. Epidemiologic data suggest that low serum vitamin D in children with asthma is associated with more symptoms, exacerbations, reduced lung function, increased medication usage and severe disease. In vitro studies have demonstrated that vitamin D enhances steroid responsiveness in adult asthmatics. Vitamin D may play an important role in pulmonary health by inhibiting inflammation, in part through maintaining regulatory T cells, and direct induction of innate antimicrobial mechanisms. More research is required to fully understand the role of vitamin D in the maintenance of airway homeostasis and address the diagnostic and therapeutic implications vitamin D may have in the future of asthma management. This review summarises the current understanding and uncertainties regarding the effect of vitamin D deficiency and insufficiency in children with asthma. Copyright © 2011.

  15. The association between phthalate exposure and asthma

    Directory of Open Access Journals (Sweden)

    Ming-Ju Tsai

    2012-07-01

    Full Text Available Asthma is a chronic inflammatory disorder of the airway, characterized by airway hyperresponsiveness. It is a disabling disease with an increasing prevalence, resulting in heavy social and economic burdens worldwide. Humans are extensively exposed to phthalates, and many epidemiological studies have shown a relationship between phthalate exposure and asthma in recent decades. Earlier experimental studies focused on inflammatory cells, demonstrating the adjuvant effects, immunomodulatory effects, or immunosuppressive effects related to phthalate exposure. Recent studies have shown that phthalates may have a direct effect on airway epithelial cells and contribute to airway remodeling, which is the cardinal pathologic characteristic of chronic asthma, with a high correlation with disease severity. Through these efforts, phthalates have been recognized as important environmental factors in the pathogenesis of asthma, but further studies are still required to elucidate the detailed mechanism. This review discusses the current status of human exposure to phthalates in Taiwan and summarizes the epidemiological and experimental evidence related to the roles of phthalate exposure in the development of asthma and associated diseases.

  16. Asthma phenotypes in childhood.

    Reddy, Monica B; Covar, Ronina A

    2016-04-01

    This review describes the literature over the past 18 months that evaluated childhood asthma phenotypes, highlighting the key aspects of these studies, and comparing these studies to previous ones in this area. Recent studies on asthma phenotypes have identified new phenotypes on the basis of statistical analyses (using cluster analysis and latent class analysis methodology) and have evaluated the outcomes and associated risk factors of previously established early childhood asthma phenotypes that are based on asthma onset and patterns of wheezing illness. There have also been investigations focusing on immunologic, physiologic, and genetic correlates of various phenotypes, as well as identification of subphenotypes of severe childhood asthma. Childhood asthma remains a heterogeneous condition, and investigations into these various presentations, risk factors, and outcomes are important since they can offer therapeutic and prognostic relevance. Further investigation into the immunopathology and genetic basis underlying childhood phenotypes is important so therapy can be tailored accordingly.

  20. New drugs for asthma.

    Science.gov (United States)

    Colice, Gene L

    2008-06-01

    The goal of asthma therapy is to reduce symptoms to the extent that patients can lead active, unlimited lives and to minimize concern about exacerbations. Unfortunately, despite advances in our understanding of the pathophysiology of asthma and the existence of consensus asthma-management guidelines, patients with asthma still suffer considerable morbidity and, on rare occasions, death. Part of the reason for suboptimal asthma control is poor adherence, by both providers and patients, to the recommended asthma regimens and guidelines. However, even under the ideal circumstances of a motivated patient and a knowledgeable physician, the available asthma drugs are not effective in all patients at all times. The market for asthma drugs has been dynamic; numerous new products have recently been approved for marketing by the Food and Drug Administration. Unfortunately, the products recently approved and those likely to enter the market soon mostly are either reformulations or combinations of established molecules. Developing new drugs to treat asthma, particularly with novel anti-inflammatory properties, should be a priority.

    Downes, Martin J; Roy, Angkana; McGinn, Thomas G; Wisnivesky, Juan P

    2010-09-01

    Exposure to indoor allergens is an established risk factor for poor asthma control. Current guidelines recommend removing pets from the home of patients with asthma. This cross-sectional study was conducted to determine the prevalence of furry pet ownership in asthmatics compared to non-asthmatics and to identify factors associated with furry pet ownership among those with asthma. Secondary analysis assessed characteristics among asthmatics that might be associated with allowing a furry pet into the bedroom. Using data from The National Asthma Survey collected from 2003 to 2004, we carried out univariate and multiple regression analyses, in 2009, to identify independent predictors of furry pet ownership in asthma sufferers after controlling for potential confounders. Overall, asthmatics were more likely to own a furry pet than nonasthmatic individuals in the general population (49.9% versus 44.8%, p ownership among asthmatics. Additionally, 68.7% of patients with asthma who own a furry pet allowed them into their bedroom. Higher income and carrying out ownership is equally or more common among asthmatics compared to those without asthma. The majority of asthmatics with furry pets allow them into the bedroom. Recognizing and addressing these problems may help decrease asthma morbidity.

    Full Text Available Abstract Background Attention deficit hyperactivity disorder (ADHD is increasingly recognized as a common disorder not only in children, but also in the adult population. Similarly, asthma also has a substantial prevalence among adults. Previous studies concerning a potential relationship between ADHD and asthma have not presented consistent results. Methods A cross-sectional study of 594 adult patients diagnosed with ADHD, compared with 719 persons from the general population. Information was collected between 1997 and 2005 using auto-questionnaires rating past and present symptoms of ADHD, co-morbid conditions, including asthma, and work status. Results The prevalence of asthma was significantly higher in the ADHD patient group compared to the controls, 24.4% vs. 11.3% respectively (OR = 2.54, 95% CI 1.89-3.44, and controls with asthma scored higher on ratings of both past and present symptoms of ADHD. Female ADHD patients had a significantly higher prevalence of asthma compared to male ADHD patients (30.9% vs. 18.2%, OR = 2.01, CI 1.36-2.95, but in controls a slight female preponderance was not statistically significant. In both ADHD patients and controls, having asthma was associated with an increased prevalence of symptoms of mood- and anxiety disorders. Conclusions The present findings point to a co-morbidity of ADHD and asthma, and these patients may represent a clinical and biological subgroup of adult patients with ADHD.

    1984-04-24

    An improved magnet which more easily provides a radially increasing magnetic field, as well as reduced fringe field and requires less power for a given field intensity. The subject invention comprises a pair of spaced, opposed magnetic poles which further comprise a pair of pole roots, each having a pole tip attached to its center. The pole tips define the gap between the magnetic poles and at least a portion of each pole tip is separated from its associated pole root. The separation begins at a predetermined distance from the center of the pole root and increases with increasing radial distance while being constant with azimuth within that portion. Magnets in accordance with the subject invention have been found to be particularly advantageous for use in large isochronous cyclotrons.

  6. Improved flare tip design

    Gogolek, P. [Natural Resources Canada, Ottawa, ON (Canada). CANMET Energy Technology Centre

    2004-07-01

    This paper discusses the testing procedures and development of an improved flare tip design. Design objectives included performance equal to or better than utility flares at low wind speed; conversion efficiency; fuel slip; smoking; significant improvement at high wind speed; and no increase in trace emissions. A description of the testing facility of the flare tip was provided, with reference to the fact that the facility allowed for realistic near full scale gas flares in a single-pass flare test facility. Other details of the facility included: an adjustable ceiling; high capacity variable speed fan; sampling ports along working section in stack; windows along working section; and air cooled walls, floor, and ceiling. The fuels used in the flare tip included natural gas, propane, gasoline and inert gases. Details of wind speed, appurtenances and turbulence generating grids were presented, with reference to continuous gas emission measurements. A list of design constraints was provided. Flare performance included wind speed, turbulence and fuel composition. A chart of conversion inefficiencies with a correlation of wind speed and turbulence, fuel flow and pipe size was also presented. Several new tip designs were fabricated for testing, with screening tests for comparison to basic pipe and ranking designs. Significant improvements were found in one of the new designs, including results with 30 per cent propane in fuel. Emissions reduction from 10 to 35 per cent were noted. It was concluded that future work should focus on evaluating improved tip for stability at low wind speeds. Fuel slips are the primary source of emissions, and it was recommended that further research is necessary to improve existing flare tips. tabs, figs.

  8. Asthma and Therapeutics: Recombinant Therapies in Asthma

    2005-03-01

    Full Text Available Abstract Numerous recombinant therapies are being investigated for the treatment of asthma. This report reviews the current status of several of these novel agents. Anti-immunoglobulin (IgE (omalizumab, Xolair markedly inhibits all aspects of the allergen challenge in subjects who have reduction of free serum IgE to undetectable levels. Several clinical studies in atopic asthma have demonstrated benefit by improved symptoms and lung function and a reduction in corticosteroid requirements. Early use in atopic asthmatics may be even more effective. Several approaches target interleukin (IL-4. Soluble IL-4 receptor has been shown to effectively replace inhaled corticosteroid; further studies are under way. Recombinant anti-IL-5 and recombinant IL-12 inhibit blood and sputum eosinophils and allergen-induced eosinophilia without any effect on airway responsiveness, allergen-induced airway responses, or allergen-induced airway hyperresponsiveness. Efalizumab, a recombinant antibody that inhibits lymphocyte trafficking, is effective in psoriasis. A bronchoprovocation study showed a reduction in allergen-induced late asthmatic response and allergen-induced eosinophilia, which suggests that it should be effective in clinical asthma. These exciting novel therapies provide not only promise of new therapies for asthma but also valuable tools for investigation of asthma mechanisms.

    Stepwise management of asthma remains an area of evolving research. Asthma is one of the most expensive chronic diseases in the United States; stepwise management is an important area of focus, with several recent guidelines recommending management. This is a review of published English language literature, focusing on management guidelines for asthma in adult and pediatric patients. Asthma is a chronic disease whose assessment of severity allows for therapeutic goals to match the impairment noted. Good evidence exists to aid risk reduction, leading to decreased emergency room visits, preventing loss of lung function in adults and lung growth in children, and optimizing pharmacotherapy with reduced side effects profile. Recent asthma management guidelines incorporate 4 components of asthma care including: monitoring of severity, patient education, controlling external triggers, and medications, including recent attention to medication adherence. Asthma is an expensive chronic disease with preventive measures leading to reduced healthcare costs. Future targeted cytokine therapy to decrease serum and blood eosinophils may become an integral part of asthma management. © 2015 ARS-AAOA, LLC.

    Although airway inflammation is an intrinsic and key feature of asthma, this response varies in its intensity and translation to clinical characteristics and responsiveness to treatment. The observations that clinical heterogeneity is an important aspect of asthma and a feature that likely dictates and determines responses to treatment in severe asthma, patient responsiveness to medication is incomplete, and risks for exacerbation are increased. The development of biologics, which target selected and specific components of inflammation, has been a promising advance to achieve asthma control in patients with severe disease.

    Belanger, Kathleen; Triche, Elizabeth W

    2008-08-01

    Indoor combustion produces both gases (eg, nitrogen dioxide, carbon monoxide) and particulate matter that may affect the development or exacerbation of asthma. Sources in the home include both heating devices (eg, fireplaces, woodstoves, kerosene heaters, flued [ie, vented] or nonflued gas heaters) and gas stoves for cooking. This article highlights the recent literature examining associations between exposure to indoor combustion and asthma development and severity. Since asthma is a chronic condition affecting both children and adults, both age groups are included in this article. Overall, there is some evidence of an association between exposure to indoor combustion and asthma, particularly asthma symptoms in children. Some sources of combustion such as coal stoves have been more consistently associated with these outcomes than other sources such as woodstoves.

    2018-02-01

    Allergic asthma is a heterogeneous disorder that defies a unanimously acceptable definition, but is generally recognized through its highly characteristic clinical expression of dyspnea and cough accompanied by clinical data that document reversible or exaggerated airway constriction and obstruction. The generally rising prevalence of asthma in highly industrialized societies despite significant therapeutic advances suggests that the fundamental cause(s) of asthma remain poorly understood. Detailed analyses of both the indoor (built) and outdoor environments continue to support the concept that not only inhaled particulates, especially carbon-based particulate pollution, pollens, and fungal elements, but also many noxious gases and chemicals, especially biologically derived byproducts such as proteinases, are essential to asthma pathogenesis. Phthalates, another common class of chemical pollutant found in the built environment, are emerging as potentially important mediators or attenuators of asthma. Other biological products such as endotoxin have also been confirmed to be protective in both the indoor and outdoor contexts. Proasthmatic factors are believed to activate, and in some instances initiate, pathologic inflammatory cascades through complex interactions with pattern recognition receptors (PRRs) expressed on many cell types, but especially airway epithelial cells. PRRs initiate the release of proallergic cytokines such as interleukin (IL)-33, IL-25, and others that coordinate activation of innate lymphoid cells type 2 (ILC2), T helper type 2 cells, and immunoglobulin E-secreting B cells that together promote additional inflammation and the major airway remodeling events (airway hyperresponsiveness, mucus hypersecretion) that promote airway obstruction. Proteinases, with airway fungi and viruses being potentially important sources, are emerging as critically important initiators of these inflammatory cascades in part through their effects on clotting

    2017-07-01

    Asthma is a leading chronic disorder among children and adolescents. Although some children outgrow asthma while transitioning into adulthood, there are others who continue to suffer from life-threatening asthmatic exacerbations. Teenagers tend to have certain misconceptions about their asthmatic condition and treatment which are rarely recognized or addressed in regular clinical consultations. After reviewing the literature in this field, we have identified that improving patient knowledge can be effective in augmenting engagement, and considerably improving their clinical outcomes. It is necessary to develop an effective educational intervention that can help Asthma patients change their perception about self-efficacy and ultimately reduce the total health care costs incurred. Hence, a sound transfer of knowledge during the transition from childcare to adult care is highly recommended. On these very lines, Georgia Institute of Technology designed an interactive educational application called Asthma Academy in conjunction with Children's Healthcare of Atlanta. This website resides in the public cloud and uses a novel animation video-based curriculum to deliver essential healthcare education to asthmatic adolescents in an interactive manner. What distinguishes it from similar initiatives is the use of a cost-effective technique to simulate caregiver-patient interactions and the ability to cater to a wide range of socio-economic statuses and educational levels. A group-based study with twenty asthma adolescents was conducted to evaluate the user acceptance and performance of Asthma Academy supplemented by regular check-ups over a period of eight to ten weeks. Observations recorded post the study clearly indicate higher levels of engagement and the systematic dissemination of information offered by Asthma Academy.

  12. Severe asthma in childhood

    Ciznar, P.

    2013-01-01

    Patients with severe asthma are clinically, physiologically and biologically a heterogeneous group. About half of children referred for medical examination for severe asthma have true severe, therapy resistant asthma. The rest of referred patients have difficult to treat asthma. Symptoms persist mostly due to drug non-compliance, inappropriate inhalation technique, persistent environmental exposures or co-morbid conditions. Compared with adults have children more frequently atopic form of severe asthma. This is associated with eosinophilia in peripheral blood and sensitization to inhaled allergens. The IgE levels are high. Therapy of co-morbidities and improvement of treatment compliance lead in most cases to full asthma control. Proportion of children will benefit from biologics like anti-IgE monoclonal antibody, administered by subcutaneous injections in 2 to 4 week intervals. By this therapy it is not only possible to suppress symptoms, but also decrease the total steroid dose and the risk of adverse effects associated with its long-term administration. By achieving a full asthma control we lower future risk of exacerbations and probably improve long-term prognosis of disease, frequently persisting for the rest of life. (author)

  13. Epidemiological Trends in Asthma

    Directory of Open Access Journals (Sweden)

    Malcolm R Sears

    1996-01-01

    Full Text Available Many markers of asthma morbidity have shown substantial increases over the past two decades, including family physician visits, use of anti-asthma medications, emergency room visits and hospital admissions. The reported prevalence of diagnosed asthma and of wheezing has increased, especially in children, with accompanying evidence of increased atopy and increased airway responsiveness. Allergen exposure and parental smoking are significant risk factors for childhood wheezing, whereas the influence of outdoor air pollution is uncertain. Increasing use of beta-agonist treatment, which appears to increase the severity of asthma by increasing early and late responses to allergen, may contribute to increased morbidity and mortality, especially if potent beta-agonists are used. Risk factors for asthma mortality include age, smoking, allergy and airway lability, as well as over-reliance on beta-agonists and poor compliance with other aspects of treatment. Following withdrawal of the potent beta-agonist fenoterol in New Zealand, both hospital admissions and mortality from asthma fell abruptly. Continued patient and physician education, with emphasis on avoidance of risk factors and use of appropriate treatment, should reduce morbidity and mortality from asthma in Canada.

  14. Airflow obstruction: is it asthma or is it COPD?

    2016-11-01

    Full Text Available Paola Rogliani, Josuel Ora, Ermanno Puxeddu, Mario Cazzola Department of Systems Medicine, Tor Vergata University of Rome, Rome, Italy Abstract: Despite the availability of guideline recommendations, diagnostic confusion between COPD and asthma appears common, and often it is very difficult to decide whether the obstruction is caused by asthma or COPD in a patient with airway obstruction. However, there are well-defined features that help in differentiating asthma from COPD in the presence of fixed airflow obstruction. Nonetheless, the presentations of asthma and COPD can converge and mimic each other, making it difficult to give these patients a diagnosis of either condition. The association of asthma and COPD in the same patient has been designated mixed asthma–COPD phenotype or overlap syndrome. However, since the absence of a clear definition and the inclusion of patients with different characteristics under this umbrella term, it may not facilitate treatment decisions, especially in the absence of clinical trials addressing this heterogeneous population. We are realizing that neither asthma nor COPD are single diseases, but rather syndromes consisting of several endotypes and phenotypes, consequently comprising a spectrum of diseases that must be recognized and adequately treated with targeted therapy. Therefore, we must treat patients by personalizing therapy on the basis of those treatable traits present in each subject.

  15. Characterization of metal-coated fiber tip for NSOM lithography by tip-to-tip scan

    International Nuclear Information System (INIS)

    Kubicova, I.; Pudis, D.; Suslik, L.; Skriniarova, J.

    2011-01-01

    For the optical field characterization, a tip-to-tip scan of two metal-coated fiber tips with circular aperture at the apex was performed. The optical field irradiated from the fiber probe in illumination mode was analyzed by NSOM represented by fiber probe in collection mode. The near-field intensity profile of the source fiber tip in the plane perpendicular to the axis of the tip was taken. Experimental stage requires high resolution 3D motion system controlled by computer (Fig. 1). The source and the detector fiber tip were placed on the moving and static part of the 3D nanoposition system, respectively. As a light source, a modulated 473 nm DPSS laser was used. After the source fiber tip characterization, the NSOM lithography was performed. In the experimental setup from Fig. 1, the detector fiber tip was replaced by a sample fixed in a vacuum holder. As a sample, a 600 nm positive photoresist AZ 5214E was spin-coated on a GaAs substrate. Exposure was carried out by irradiation of the sample at desired positions through the fiber tip aperture. The sample was developed in AZ 400K developer for 30 s and rinsed in DI water. A promising tip-to-tip scanning technique for characterization of metal-coated fiber tips with aperture at the apex was presented. Nearly-circular aperture shapes were documented from NSOM measurements with diameter estimated to be less than 460 nm. By knowing the source-detector distance and the FWHM of the near-field intensity profile, the tip-to-tip scan proves an easy and fast method to analyze the fiber tip aperture properties. The fiber tip resolution was confirmed by preparation of 2D planar structures in thin photoresist layer, where the NSOM lithography uses the metal-coated fiber tip characterized in previous section.

  16. Omalizumab therapy for children and adolescents with severe allergic asthma.

    Science.gov (United States)

    Romano, Ciro

    2015-01-01

    Omalizumab, a therapeutic humanized monoclonal antibody specific for human IgE, was introduced in clinical practice more than a decade ago as an add-on therapy for moderate-to-severe allergic asthma in patients aged ≥12 years. Omalizumab has been demonstrated to be effective in adults with uncontrolled persistent asthma, with an excellent safety profile. In simple terms, omalizumab works by inhibiting the allergic cascade, that is, by neutralization of the circulating free IgE. This leads to reduction in the quantity of cell-bound IgE, downregulation of high-affinity IgE receptors, and, eventually, prevention of mediator release from effector cells. Evidence is far less abundant on the role of omalizumab in pediatric asthma. Although efficacy and safety of omalizumab in children and adolescents with uncontrolled, persistent allergic asthma has been recognized as well, further studies are needed to clarify a number of open questions in this specific patient population.

  17. Eosinophilic Endotype of Asthma.

    Aleman, Fernando; Lim, Hui Fang; Nair, Parameswaran

    2016-08-01

    Asthma is a heterogeneous disease that can be classified into different clinical endotypes, depending on the type of airway inflammation, clinical severity, and response to treatment. This article focuses on the eosinophilic endotype of asthma, which is defined by the central role that eosinophils play in the pathophysiology of the condition. It is characterized by elevated sputum and/or blood eosinophils on at least 2 occasions and by a significant response to treatments that suppress eosinophilia. Histopathologic demonstration of eosinophils in the airways provides the most direct diagnosis of eosinophilic asthma; but it is invasive, thus, impractical in clinical practice.

    2004-01-01

    Bronchial asthma is one of the most frequent respiratory diseases in childhood. Recurrent emergency department visits for asthma produce anxiety and high costs for the system of health and for the family. It is important to know the factors related to these recurrent emergency department visits to assist the targeting of appropriate future interventions aimed at reducing this avoidable presentation. The objective of the present study was to identify factors associated with recurrent emergency department visits for asthma in children liable to be modified by means of an education program. Data obtained from a survey of parents of 146 pediatric patients with asthma attending an asthma clinic and educational program were examined. Parents completed an asthma knowledge and attitudes questionnaire that also included other socio demographic and illness-related variables, including the number of consultations to emergency department by their children asthma in the previous 6 months. Of the 146 asthmatic patients enrolled, 41 (28.1%) consulted repeatedly to the emergency department for asthma. After controlling for age of the patient, educational level of the parents, and functional severity of the disease, we found that parents who reported that they attended to emergency room because asthma attacks of their children were severe enough to go elsewhere (OR, 4.57; CL95%, 1.76- 11.85; P = 0.002), parents who reported that asthma medications should be administered only in symptomatic moments (OR 278, CL 95%, 1.05 - 7.33, P = 0.038 and parents that did not recognize the fact that asthma attacks can be avoided if medications are administered when there are no symptoms (between asthma attacks) (OR 2.61; CL95%; 1.03 - 7.02; p = 0,045), had a greater probability to attend rapidly the emergency room because of asthma of their children. The fact that parents of asthmatic patients have thought that asthma medications should be administered only in symptomatic patients, that they hadn

    2018-05-21

    An asthma attack or exacerbation signals treatment failure. Most attacks are preventable and failure to recognize risk of asthma attacks are well recognized as risk factors for future attacks and even death. Of the 19 recommendations made by the United Kingdom National Review of Asthma Deaths (NRAD) (1) only one has been partially implemented-a National Asthma Audit; however, this hasn't reported yet. The Harrow Clinical Commissioning Group (CCG) in London implemented a clinical asthma audit on 291 children and young people aged under 19 years (CYP) who had been treated for asthma attacks in 2016. This was funded as a Local Incentive Scheme (LIS) aimed at improving quality health care delivery. Two years after the publication of the NRAD report it is surprising that risks for future attacks were not recognized, that few patients were assessed objectively during attacks and only 10% of attacks were followed up within 2 days. However, it is encouraging that CYP hospital admissions following the audit were reduced by 16%, with clear benefit for patients, their families and the local health economy. This audit has provided an example of how clinicians can focus learning on patients who have had asthma attacks and utilize these events as a catalyst for active reflection in particular on modifiable risk factors. Through identification of these risks and active optimization of management, preventable asthma attacks could become 'never events'.

    Metabolic syndrome (MetS) is a syndrome that involves at least three disorders dyslipidemia, insulin resistance, obesity and/or hypertension. MetS has been associated with several chronic diseases in the adulthood; however, in the recent years, the syndrome was redefined in children. Girls with early menarche and asthma, and children with MetS and asthma that reach adulthood appear to have higher risk to develop severe or difficult to control asthma and a higher probability to suffer cardiovascular diseases. It has been proposed that patients with MetS and endocrinological disorders should be considered a different entity in which pharmacologic treatment should be adjusted according to the individual. Recent patents on the field have addressed new issues on how endocrine control should be managed along with asthma therapeutics. In the near future, new approaches should decrease the high morbidity and mortality associated to these types of patients.

    Full Text Available Asthma is a chronic disorder affecting millions of people worldwide. The prevalence of asthma is around 300 million and is expected to increase another 100 million by 2025. Obesity, on the other hand, also affects a large number of individuals. Overweight in adults is defined when body mass index (BMI is between 25 to 30 kg/m 2 and obesity when the BMI >30 kg/m 2 . It has been a matter of interest for researchers to find a relation between these two conditions. This knowledge will provide a new insight into the management of both conditions. At present, obese asthma patients may be considered a special category and it is important to assess the impact of management of obesity on asthma symptoms.

  20. Evolving Concepts of Asthma

    Science.gov (United States)

    Ray, Anuradha; Wenzel, Sally E.

    2015-01-01

    Our understanding of asthma has evolved over time from a singular disease to a complex of various phenotypes, with varied natural histories, physiologies, and responses to treatment. Early therapies treated most patients with asthma similarly, with bronchodilators and corticosteroids, but these therapies had varying degrees of success. Similarly, despite initial studies that identified an underlying type 2 inflammation in the airways of patients with asthma, biologic therapies targeted toward these type 2 pathways were unsuccessful in all patients. These observations led to increased interest in phenotyping asthma. Clinical approaches, both biased and later unbiased/statistical approaches to large asthma patient cohorts, identified a variety of patient characteristics, but they also consistently identified the importance of age of onset of disease and the presence of eosinophils in determining clinically relevant phenotypes. These paralleled molecular approaches to phenotyping that developed an understanding that not all patients share a type 2 inflammatory pattern. Using biomarkers to select patients with type 2 inflammation, repeated trials of biologics directed toward type 2 cytokine pathways saw newfound success, confirming the importance of phenotyping in asthma. Further research is needed to clarify additional clinical and molecular phenotypes, validate predictive biomarkers, and identify new areas for possible interventions. PMID:26161792

  1. C-Type Lectin Receptors in Asthma

    Directory of Open Access Journals (Sweden)

    Sabelo Hadebe

    2018-04-01

    Full Text Available Asthma is a heterogeneous disease that affects approximately 300 million people worldwide, largely in developed countries. The etiology of the disease is poorly understood, but is likely to involve specific innate and adaptive responses to inhaled microbial components that are found in allergens. Fungal-derived allergens represent a major contributing factor in the initiation, persistence, exacerbation, and severity of allergic asthma. C-type lectin like receptors, such as dectin-1, dectin-2, DC-specific intercellular adhesion molecule 3-grabbing nonintegrin, and mannose receptor, recognize many fungal-derived allergens and other structurally similar allergens derived from house dust mites (HDM. In some cases, the fungal derived allergens have been structurally and functionally identified alongside their respective receptors in both humans and mice. In this review, we discuss recent understanding on how selected fungal and HDM derived allergens as well as their known or unknown receptors shape allergic airway diseases.

    Clusters of asthma in athletes have been insufficiently studied. Therefore, the present study aimed to characterize asthma phenotypes in elite athletes using latent class analysis (LCA) and to evaluate its association with the type of sport practiced. In the present cross-sectional study, an analysis of athletes' records was carried out in databases of the Portuguese National Anti-Doping Committee and the Norwegian School of Sport Sciences. Athletes with asthma, diagnosed according to criteria given by the International Olympic Committee, were included for LCA. Sports practiced were categorized into water, winter and other sports. Of 324 files screened, 150 files belonged to asthmatic athletes (91 Portuguese; 59 Norwegian). LCA retrieved two clusters: "atopic asthma" defined by allergic sensitization, rhinitis and allergic co-morbidities and increased exhaled nitric oxide levels; and "sports asthma", defined by exercise-induced respiratory symptoms and airway hyperesponsiveness without allergic features. The risk of developing the phenotype "sports asthma" was significantly increased in athletes practicing water (OR = 2.87; 95% CI [1.82-4.51]) and winter (OR = 8.65; 95% CI [2.67-28.03]) sports, when compared with other athletes. Two asthma phenotypes were identified in elite athletes: "atopic asthma" and "sports asthma". The type of sport practiced was associated with different phenotypes: water and winter sport athletes had three- and ninefold increased risk of "sports asthma". Recognizing different phenotypes is clinically relevant as it would lead to distinct targeted treatments.

    Asthma is a common chronic condition. Work-related asthma (WRA) has a large socioeconomic impact and is increasing in prevalence but remains under-recognized. Although international guidelines recommend patient education, no widely available educational tool exists. To develop a WRA educational website for adults with asthma. An evidence-based database for website content was developed, which applied evidence-based website design principles to create a website prototype. This was subsequently tested and serially revised according to patient feedback in three moderated phases (one focus group and two interview phases), followed by face validation by asthma educators. Patients (n=10) were 20 to 28 years of age; seven (70%) were female, three (30%) were in university, two (20%) were in college and five (50%) were currently employed. Key format preferences included: well-spaced, bulleted text; movies (as opposed to animations); photos (as opposed to cartoons); an explicit listing of website aims on the home page; and an exploding tab structure. Participants disliked integrated games and knowledge quizzes. Desired informational content included a list of triggers, prevention⁄control methods, currently available tools and resources, a self-test for WRA, real-life scenario presentations, compensation information, information for colleagues on how to react during an asthma attack and a WRA discussion forum. The website met the perceived needs of young asthmatic patients. This resource could be disseminated widely and should be tested for its effects on patient behaviour, including job choice, workplace irritant⁄allergen avoidance and⁄or protective equipment, asthma medication use and physician prompting for management of WRA symptoms.

    Asthma is a complex and heterogeneous disease with several phenotypes, including an allergic asthma phenotype characterized by TH2 cytokine production and associated with allergen sensitization and adaptive immunity. Asthma also includes nonallergic asthma phenotypes, such as asthma associated with exposure to air pollution, infection, or obesity, that require innate rather than adaptive immunity. These innate pathways that lead to asthma involve macrophages, neutrophils, natural killer T cells, and innate lymphoid cells, newly described cell types that produce a variety of cytokines, including IL-5 and IL-13. We review the recent data regarding innate lymphoid cells and their role in asthma. Copyright © 2014 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc. All rights reserved.

    Full Text Available Observers have always been fascinated by soaring birds. An interesting feature of these birds is the existence of few feathers extending from the tip of the wing. In this paper, small lifting surfaces were fitted to the tip of a NACA0012 wing in a fashion similar to that of wing tip feathers. Experimental measurements of induced drag, longitudinal static stability and trailing vortex structure were obtained.The tests showed that adding wing tip surfaces (sails decreased the induced drag factor and increased the longitudinal static stability. Results identified two discrete appositely rotated tip vortices and showed the ability of wing tip surfaces to break them down and to diffuse them.

    Obesity is a risk factor for asthma, but standard asthma drugs have reduced efficacy in the obese. Obesity alters the gastrointestinal microbial community structure. This change in structure contributes to some obesity-related conditions and also could be contributing to obesity-related asthma. Although currently unexplored, obesity may also be altering lung microbiota. Understanding the role of microbiota in obesity-related asthma could lead to novel treatments for these patients.

    2017-10-01

    Patients with uncontrolled asthma are at a greater risk of asthma attacks requiring emergency room visits or hospital admissions. Takotsubo cardiomyopathy is potentially a significant complication in a course of status asthmaticus. We describe a 43-year-old female patient who presented with status asthmaticus that was further complicated with takotsubo cardiomyopathy. Recognizing apical ballooning syndrome is challenging in patients with a history of respiratory disease because the symptoms of the last entity may complicate the diagnostic approach. It is difficult to distinguish clinically apical ballooning syndrome from the acute airway exacerbation itself. Both asthma and takotsubo cardiomyopathy share the same clinical presentation with dyspnea and chest tightness. In our patient, the electrocardiographic abnormalities, the rapidly reversible distinctive characteristics of echocardiography, and the modest elevation of serum cardiac biomarkers levels, in combination with the presence of a stress trigger (severe asthma attack), strongly supported the diagnosis of broken heart syndrome. Clinicians should re-evaluate asthma management and be aware of the complications associated with asthma attacks such as stress-induced cardiomyopathy.

    Lima, John J.; Blake, Kathryn V.; Tantisira, Kelan G.; Weiss, Scott T.

    2009-01-01

    Purpose of review Patient response to the asthma drug classes, bronchodilators, inhaled corticosteroids and leukotriene modifiers, are characterized by a large degree of heterogeneity, which is attributable in part to genetic variation. Herein, we review and update the pharmacogenetics and pharmaogenomics of common asthma drugs. Recent findings Early studies suggest that bronchodilator reversibility and asthma worsening in patients on continuous short-acting and long-acting β-agonists are related to the Gly16Arg genotype for the ADRB2. More recent studies including genome-wide association studies implicate variants in other genes contribute to bronchodilator response heterogeneity and fail to replicate asthma worsening associated with continuous β-agonist use. Genetic determinants of the safety of long-acting β-agonist require further study. Variants in CRHR1, TBX21, and FCER2 contribute to variability in response for lung function, airways responsiveness, and exacerbations in patients taking inhaled corticosteroids. Variants in ALOX5, LTA4H, LTC4S, ABCC1, CYSLTR2, and SLCO2B1 contribute to variability in response to leukotriene modifiers. Summary Identification of novel variants that contribute to response heterogeneity supports future studies of single nucleotide polymorphism discovery and include gene expression and genome-wide association studies. Statistical models that predict the genomics of response to asthma drugs will complement single nucleotide polymorphism discovery in moving toward personalized medicine. PMID:19077707

    Dysmorphophobia is a psychiatric condition which frequently presents in the clinics of dermatologists and plastic surgeons. This disorder (also called body dysmorphic disorder) is troublesome to the patient whilst being confusing for the doctor. This commonly undiagnosed condition can be detected by a few simple steps. Timely referral to a psychiatrist benefits most patients suffering from it. This article describes with a case vignette, how to recognize body dysmorphic disorder presenting in the dermatological or aesthetic surgery set up. Diagnostic criteria, eitiology, approach to patient, management strategy and when to refer are important learning points. The importance of recognizing this disorder timely and referring the patient to the psychiatrist for appropriate treatment is crucial. This article covers all aspects of body dysmorphic disorder relevant to dermatologists and plastic surgeons and hopes to be useful in a better understanding of this disorder. PMID:26644741

    Asthma is one of the most common chronic medical conditions. The usual treatment includes quick relief bronchodilator medications of the sympathomimetic class and controller medications that may include the long-acting inhaled bronchodilator salmeterol. Mild adverse cardiac and central nervous system effects are common with these medications, requiring modifications in dose or occasionally switching to a different medication. Both asthma and thyroid disease are common disorders that occasionally occur together. Hyperthyroidism may exacerbate asthma. Many symptoms of hyperthyroidism are identical to the adverse effects of the commonly used inhaled bronchodilators and include tremor, nervousness, tachycardia, wide pulse pressure, palpitations, emotional lability, agitation, nightmares, aggressive behavior, and diarrhea. In this report we describe a patient with hyperthyroidism whose symptoms initially were thought to be adverse effects of the inhaled bronchodilator medications.

  7. Flavonoids and Asthma

    Tanaka, Toshio; Takahashi, Ryo

    2013-01-01

    Asthma is a chronic disease, characterized by airway inflammation, airflow limitation, hyper-reactivity and airway remodeling. It is believed that asthma is caused by the interaction between genetic and environmental factors. The prevalence of allergic diseases, including asthma, has increased worldwide during the past two decades. Although the precise reasons that have caused this increase remain unknown, dietary change is thought to be one of the environmental factors. Flavonoids, which are polyphenolic plant secondary metabolites ubiquitously present in vegetables, fruits and beverages, possess antioxidant and anti-allergic traits, as well as immune-modulating activities. Flavonoids are powerful antioxidants and anti-allergic nutrients that inhibit the release of chemical mediators, synthesis of Th2 type cytokines, such as interleukin (IL)-4 and IL-13, and CD40 ligand expression by high-affinity immunoglobulin E (IgE) receptor-expressing cells, such as mast cells and basophils. They also inhibit IL-4-induced signal transduction and affect the differentiation of naïve CD4+ T cells into effector T-cells through their inhibitory effect on the activation of the aryl hydrocarbon receptor. Various studies of flavonoids in asthmatic animal models have demonstrated their beneficial effects. The results of several epidemiological studies suggest that an increase in flavonoid intake is beneficial for asthma. Moreover, clinical trials of flavonoids have shown their ameliorative effects on symptoms related to asthma. However, these human studies are currently limited; further validation is required to clarify whether an appropriate intake of flavonoids may constitute dietary treatment and for part of a preventive strategy for asthma.

Obesity, on the other hand, also affects a large number of individuals. Overweight in adults is defined when body mass index (BMI) is between 25 to 30 kg/m 2 and obesity when the BMI >30 kg/m 2 . It has been a matter of interest for researchers to find a relation between these two conditions. This knowledge will provide a ...

    Asthma control is emphasized by new guidelines but remains poor in many children. Evaluation of control relies on subjective patient recall and may be overestimated by health-care professionals. This study assessed the value of spirometry and fractional exhaled nitric oxide (FeNO) measurements, used alone or in combination, in models developed by a machine learning approach in the objective classification of asthma control according to Global Initiative for Asthma guidelines and tested the model in a second group of children with asthma. Fifty-three children with persistent atopic asthma underwent two to six evaluations of asthma control, including spirometry and FeNO. Soft computing evaluation was performed by means of artificial neural networks and principal component analysis. The model was then tested in a cross-sectional study in an additional 77 children with allergic asthma. The machine learning method was not able to distinguish different levels of control using either spirometry or FeNO values alone. However, their use in combination modeled by soft computing was able to discriminate levels of asthma control. In particular, the model is able to recognize all children with uncontrolled asthma and correctly identify 99.0% of children with totally controlled asthma. In the cross-sectional study, the model prospectively identified correctly all the uncontrolled children and 79.6% of the controlled children. Soft computing analysis of spirometry and FeNO allows objective categorization of asthma control status.

    2008-01-01

    Full Text Available The article highlights the results of the act test based bronchial asthma supervision evaluation among teenagers and defines the interrelation of the objective and subjective asthma supervision parameters. The researchers examined 214 male teenagers aged from 16 to 18, suffering from the bronchial asthma, who were sent to the allergy department to verify the diagnosis. Bronchial asthma supervision evaluation was assisted by the act test. The research has showed that over a half (56% of teenagers, suffering from mild bronchial asthma, mention its un control course, do not receive any adequate pharmacotherapy and are consequently a risk group in terms of the bronchial asthma exacerbation. Act test results correlate with the functional indices (fev1, as well as with the degree of the bronchial hyperresponsiveness, which is one of the markers of an allergic inflammation in the lower respiratory passages.Key words: bronchial asthma supervision, act test, teenagers.

  13. Bronchial Thermoplasty in Asthma

    Directory of Open Access Journals (Sweden)

    Wayne Mitzner

    2006-01-01

    Full Text Available In this review we discuss the potential of a new procedure, termed Bronchial Thermoplasty to prevent serious consequences resulting from excessive airway narrowing. The most important factor in minimizing an asthmatic attack is limiting the degree of smooth muscle shortening. The premise that airway smooth muscle can be either inactivated or obliterated without any long-term alteration of other lung tissues, and that airway function will remain normal, albeit with reduced bronchoconstriction, has now been demonstrated in dogs, a subset of normal subjects, and mild asthmatics. Bronchial Thermoplasty may thus develop into a useful clinical procedure to effectively impair the ability for airway smooth muscle to reach the levels of pathologic narrowing that characterizes an asthma attack. It may also enable more successful treatment of asthma patients who are unresponsive to more conventional therapies. Whether this will remain stable for the lifetime of the patient still remains to be determined, but at the present time, there are no indications that the smooth muscle contractility will return. This successful preliminary experience showing that Bronchial Thermoplasty could be safely performed in patients with asthma has led to an ongoing clinical trial at a number of sites in Europe and North America designed to examine the effectiveness of this procedure in subjects with moderately severe asthma.

  14. Stress and asthma

    Directory of Open Access Journals (Sweden)

    Shoji Nagata

    1999-01-01

    Full Text Available Three factors in recent medical research and treatment (advances in the field of psychoneuroimmunology, epidemiological evidence regarding important interaction between psychosocial factors and development of disease, and the recognition of the importance of patient education for self-management of asthma have led clinicians and researchers to reconsider the role of psychosocial stress in asthma. There are many reports suggesting that stressful life events, family problems and a behavior pattern that increases psychological conflict may influence the development or relapse of asthma and influence its clinical course. Depression is known as one of the risk factors of fatal asthmatic attack. In laboratory studies, about 20% of asthmatics were considered reactors who showed an airway change after exposure to emotional stress. Studies regarding the pathway of stress effect on allergy and asthma are reviewed and discussed from the standpoint of psychoneuroimmunology; for example, the enhancement of IgE production and increased susceptibility to respiratory infection by stress, conditioned anaphylaxis and nerve/mast cell interaction, the effect of stress on various bronchial responses and the inhibition of the immediate and late asthmatic response by anterior hypothalamic lesioning.

    Townley, Robert G; Agrawal, Swati; Sapkota, Kiran

    2010-11-01

    Omalizumab is of proven efficacy in the treatment of severe allergic bronchial asthma and works through inhibiting the activity of IgE and the allergic immune mechanism IgE mediates. It has been demonstrated to be efficacious in children with asthma but is not approved by the FDA for use in children below 12 years of age. Omalizumab is a 95% humanized monoclonal antibody that binds to circulating IgE at the same site on the Fc domain as the high-affinity IgE receptor, FcϵRI. This blocks the interaction between IgE and mast cells and basophils, thereby preventing the release of inflammatory mediators that cause allergic signs and symptoms. From the review of the literatures and statements from the FDA, Genentec and Novartis, the reader will gain a better appreciation of the value of omalizumab in treatment of severe asthma and the current status of its reported side effects. Omalizumab is of proven efficacy in adults and children with severe asthma and allows a markedly reduced dependence on oral and inhaled corticosteroids and decreased hospitalizations. A potential mechanism of omalizumab's effect on thrombus formation and cardiovascular effect is postulated.

    Recent findings report that wild animals can recognize individual humans. To explain how the animals distinguish humans, two hypotheses are proposed. The high cognitive abilities hypothesis implies that pre-existing high intelligence enabled animals to acquire such abilities. The pre-exposure to stimuli hypothesis suggests that frequent encounters with humans promote the acquisition of discriminatory abilities in these species. Here, we examine individual human recognition abilities in a wild Antarctic species, the brown skua (Stercorarius antarcticus), which lives away from typical human settlements and was only recently exposed to humans due to activities at Antarctic stations. We found that, as nest visits were repeated, the skua parents responded at further distances and were more likely to attack the nest intruder. Also, we demonstrated that seven out of seven breeding pairs of skuas selectively responded to a human nest intruder with aggression and ignored a neutral human who had not previously approached the nest. The results indicate that Antarctic skuas, a species that typically inhabited in human-free areas, are able to recognize individual humans who disturbed their nests. Our findings generally support the high cognitive abilities hypothesis, but this ability can be acquired during a relatively short period in the life of an individual as a result of interactions between individual birds and humans.

    2017-01-01

    The worldwide prevalence of childhood asthma has been increasing considerably, and the protection afforded by breastfeeding in its development has been the subject of controversy for more than 80 years. Previous systematic reviews have generally found a protective effect of breastfeeding on allergic outcomes, although many studies have methodological limitations. Although breastfeeding is protective against lower respiratory tract infection during infancy, such protection has not been demonstrated for asthma in all studies. Breastfeeding has health benefits for the mother and child. Exclusive breastfeeding for the first 6 months of an infant's life, with continued breastfeeding for up to 2 years or longer, is recognized as the "gold" standard for infant feeding because human milk is uniquely suited to the human infant, and its nutritional content and bioactivity promote a healthy development. There is increasing concern that the practice of delaying complementary foods until 6 months may exacerbate the risk of allergic disease. Breast milk contains immunological components that protect against infections and allergic disease in infancy. The composition of human breast milk is complex, containing factors that interact with the infant immune system and intestinal milieu including allergens, cytokines, immunoglobulins, polyunsaturated fatty acids, and chemokines. Transforming growth factor β is a cytokine in human milk involved in maintaining intestinal homeostasis, inflammation regulation, and oral tolerance development. Modern day society, with increased standards of hygiene, has changed the gut flora of Western infants, potentially impacting the risk of developing immune-mediated diseases including allergic disease and asthma. Microbial diversity is intrinsic to healthy immune maturation and function. Compared to breastfed infants, formula-fed infants had lower bacterial diversity and an altered intestinal microbiota in the first few weeks of life associated with

    There comes a time in every field of science when things suddenly change. While it might not be immediately apparent that things are different, a tipping point has occurred. Biology is now at such a point. The reason is the introduction of high-throughput genomics-based technologies. I am not talking about the consequences of the sequencing of the human genome (and every other genome within reach). The change is due to new technologies that generate an enormous amount of data about the molecular composition of cells. These include proteomics, transcriptional profiling by sequencing, and the ability to globally measure microRNAs and post-translational modifications of proteins. These mountains of digital data can be mapped to a common frame of reference: the organism’s genome. With the new high-throughput technologies, we can generate tens of thousands of data points from each sample. Data are now measured in terabytes and the time necessary to analyze data can now require years. Obviously, we can’t wait to interpret the data fully before the next experiment. In fact, we might never be able to even look at all of it, much less understand it. This volume of data requires sophisticated computational and statistical methods for its analysis and is forcing biologists to approach data interpretation as a collaborative venture.

  6. Tipping the scales.

    Science.gov (United States)

    1998-12-01

    In the US, the October 1998 murder of a physician who performed abortions was an outward manifestation of the insidious battle against legal abortion being waged by radical Christian social conservatives seeking to transform the US democracy into a theocracy. This movement has been documented in a publication entitled, "Tipping the Scales: The Christian Right's Legal Crusade Against Choice" produced as a result of a 4-year investigation conducted by The Center for Reproductive Law and Policy. This publication describes how these fundamentalists have used sophisticated legal, lobbying, and communication strategies to further their goals of challenging the separation of church and state, opposing family planning and sexuality education that is not based solely on abstinence, promoting school prayer, and restricting homosexual rights. The movement has resulted in the introduction of more than 300 anti-abortion bills in states, 50 of which have passed in 23 states. Most Christian fundamentalist groups provide free legal representation to abortion clinic terrorists, and some groups solicit women to bring specious malpractice claims against providers. Sophisticated legal tactics are used by these groups to remove the taint of extremism and mask the danger posed to US constitutional principles being posed by "a well-financed and zealous brand of radical lawyers and their supporters."

    Full Text Available Asthma is one of the chronic diseases which have are widely seen among the children. The disease has recently been in the increase all over the world and affects many children. In a study conducted with International Study of Asthma and Allergies in Childhood (ISAAC method, it was found out that prevalence of childhood asthma was 17.1%. Participation in sportive activities by the children with asthma, which is today considered as a part of asthma treatment program, makes contributions to their physical, mental and psychological development and increases their quality of life. The most recommended sports for the children with asthma are swimming and water sports. Sports like tennis and volleyball are too advised. Choice of sports depends on severity of asthma, child and #8217;s choice and whether or not asthma is kept under control. Nursing approaches for the children with asthma include correction of symptoms, training of children and their families, assistance with disease adaptation, continuing asthma care at home and interventions to make children lead healthy activities of daily life of children. With protective measures to be taken by families and children; children should be encourage for sportive activities. [TAF Prev Med Bull 2014; 13(3.000: 241-244

    Full Text Available Objectives: About 5–10% of asthmatics do not respond well to standard treatment plan. Occupational exposure may be one of the factors that can be linked with treatment failure. The aim of the study was to assess the prevalence of work-related asthma (WRA among adult asthmatics under follow up in an outpatient allergy clinic and to create a useful tool for detecting individuals with possible WRA. Material and Methods: Preliminary 5-question questionnaire designed to recognize WRA was presented to 300 asthmatics. All patients with positive preliminary verification along with 50 subjects from control group were asked to fill up a detailed questionnaire. The WRA was diagnosed by positive match for asthma symptoms in combination with workplace exposure indicated in the detailed WRA questionnaire followed by confirmation of each WRA case by detailed exposure analysis. Results: Work-related asthma was recognized in 63 subjects (21% of study group. The preliminary questionnaire has 76.9% sensitivity and 94% specificity in recognition of WRA. Occupational exposure to irritants is a risk factor of WRA recognition (relative risk (RR = 2.09 (1.44:3.03. Working in exposure-free environment is a factor against WRA recognition (RR = 0.38 (0.24:0.61. Among subjects with work-related asthma, the uncontrolled course of the disease is significantly more frequent (p = 0.012. Subjects with WRA more often report sickness absenteeism due to asthma than those without WRA (9.6% vs. 3.2%, respectively, but the observed differences did not reach the statistical significance. Conclusions: Short 5-question questionnaire seems to be a promising tool to detect individuals with possible work-related asthma in the outpatient setting for further evaluation and additional attention.

  9. [Anesthesia in bronchial asthma].

    Bremerich, D H

    2000-09-01

    Asthma is defined as a chronic inflammatory airway disease in response to a wide variety of provoking stimuli. Characteristic clinical symptoms of asthma are bronchial hyperreactivity, reversible airway obstruction, wheezing and dyspnea. Asthma presents a major public health problem with increasing prevalence rates and severity worldwide. Despite major advances in our understanding of the clinical management of asthmatic patients, it remains a challenging population for anesthesiologists in clinical practice. The anesthesiologist's responsibility starts with the preoperative assessment and evaluation of the pulmonary function. For patients with asthma who currently have no symptoms, the risk of perioperative respiratory complications is extremely low. Therefore, pulmonary function should be optimized preoperatively and airway obstruction should be controlled by using steroids and bronchodilators. Preoperative spirometry is a simple means of assessing presence and severity of airway obstruction as well as the degree of reversibility in response to bronchodilator therapy. An increase of 15% in FEV1 is considered clinically significant. Most asymptomatic persons with asthma can safely undergo general anesthesia with and without endotracheal intubation. Volatile anesthetics are still recommended for general anesthetic techniques. As compared to barbiturates and even ketamine, propofol is considered to be the agent of choice for induction of anesthesia in asthmatics. The use of regional anesthesia does not reduce perioperative respiratory complications in asymptomatic asthmatics, whereas it is advantageous in symptomatic patients. Pregnant asthmatic and parturients undergoing anesthesia are at increased risk, especially if regional anesthetic techniques are not suitable and prostaglandin and its derivates are administered for abortion or operative delivery. Bronchial hyperreactivity associated with asthma is an important risk factor of perioperative bronchospasm. The

    Full Text Available 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.

    In BWR nuclear power stations the Traversing Incore Probe (TIP) system is one of the most important components in reactor monitoring and control. In previous TIP systems, however, operators have suffered from the complexity of operation and long operation time required. The system presented in this paper realizes the automatic operation of the TIP system by monitoring and driving it with a process computer. This system significantly reduces the burden on customer operators and improves plant efficiency by simplifying the operating procedure, augmenting the accuracy of the measured data, and shortening operating time. The process computer is one of the PODIA (Plant Operation by Displayed Information Automation) systems. This computer transfers control signals to the TIP control panel, which in turn drives equipment by microprocessor control. The process computer contains such components as the CRT/KB unit, the printer plotter, the hard copier, and the message typers required for efficient man-machine communications. Its operation and interface properties are described

  8. Tip model of cold fission

    International Nuclear Information System (INIS)

    Goennenwein, F.; Boersig, B.

    1991-01-01

    Cold fission is defined to be the limiting case of nuclear fission where virtually all of the available energy is converted into the total kinetic energy of the fragments. The fragments have, therefore, to be born in or at least close to their respective ground states. Starting from the viewpoint that cold fission corresponds to most compact scission configurations, energy constraints have been exploited to calculate minimum tip distances between the two nascent fragments in binary fission. Crucial input parameters to this tip model of cold fission are the ground-state deformations of fragment nuclei. It is shown that the minimum tip distances being compatible with energy conservation vary strongly with both the mass and charge fragmentation of the fission prone nucleus. The tip distances refer to nuclei with equivalent sharp surfaces. In keeping with the size of the surface width of leptodermous nuclei, only configurations where the tip distances are smaller than a few fm may be considered as valid scission configurations. From a comparison with experimental data on cold fission this critical tip distance appears to be 3.0 fm for the model parameters chosen. Whenever the model calculation yields tip distances being smaller than the critical value, a necessary condition for attaining cold fission is considered to be fulfilled. It is shown that this criterion allows to understand in fair agreement with experiment which mass fragmentations are susceptible to lead to cold fission and which fragment-charge divisions are the most favored in each isobaric mass chain. Being based merely on energy arguments, the model cannot aim at predicting fragment yields in cold fission. However, the tip model proposed appears well suited to delineate the phase space where cold fission phenomena may come into sight. (orig.)

  9. Asthma myths, controversies, and dogma.

    2015-03-01

    Although the symptom complex we call asthma has been well described since antiquity, our understanding of the causes and therapy of asthma has evolved. Even with this evolution in our understanding, there are persistent myths (widely held but false beliefs) and dogma (entrenched beliefs) regarding the causes, classification, and therapy of asthma. It is sobering that some of the knowledge we hold dear today, will become the mythology of tomorrow. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Although asthma is a condition that is managed in the outpatient setting in most patients, the poorly controlled and severe cases pose a major challenge to the health-care team. Recognition of the more common insidious and the less common rapid onset "acute asphyxic" asthma are important. The intensivist needs to be familiar with the factors that denote severity of the exacerbation. The management of respiratory failure in asthma, including pharmacologic and mechanical ventilation, are discus...

  12. Studies on provoked asthma

    International Nuclear Information System (INIS)

    Munkner, L.; Bundgaard, A.

    1982-01-01

    A group of adult patients with perennial bronchial asthma has been studied as to lung perfusion and alveolar ventilation (81m-Kr) at rest and after provocation of an acute attack. Asthma was provoked by exercise and by histamine inhalation. After provocation the peak expiratory flow values were reduced to less than 80% of the base line values. Perfusion was often deranged. Regional ventilation changed rapidly after provocation and not always in the same fashion after exercise and histamine. During attacks lung volume increased. The expansion decreased (in parallel with increased peak expiratory flow) after inhalator of a #betta#-2 agonist (terbutaline). 81m-Kr offers unique opportunities for studying acute regional changes in alveolar ventilation.

  13. Practical Considerations for the Diagnosis and Management of Asthma in Older Adults.

    Science.gov (United States)

    Yawn, Barbara P; Han, MeiLan K

    2017-11-01

    Although often considered a disease of childhood, the prevalence of asthma in US adults aged 65 years or older is similar to that in children, with the number of older patients needing care for asthma likely to continue to increase. As with most chronic diseases, there are challenges associated with the diagnosis and management of asthma in an older population. This review discusses these challenges, suggesting practical management strategies for primary care physicians and their teams. Asthma comprises a spectrum of phenotypes, some associated with adult onset. The symptoms and characteristics of patients with late-onset asthma can differ from those of patients with early-onset disease. Furthermore, older patients may fail to recognize respiratory symptoms as abnormal and have other comorbidities, complicating the differential diagnosis of asthma. Once diagnosed, the long-term goals of asthma management are no different in older adults than in anyone with asthma, with inhaled corticosteroids being the cornerstone of therapy. Comorbid conditions become more common with age and have a direct impact on a patient's respiratory symptoms and potential adverse effects of therapy, thereby influencing the choice of therapies and delivery systems and potentially increasing the likelihood of complex polypharmacy. In conclusion, asthma, although traditionally considered a disease of the young, should be considered as a potential diagnosis in older adults with respiratory symptoms, even without a history of asthma or allergies. As with all patients, the primary goals of asthma management in older adults are symptom control and exacerbation reduction. Copyright © 2017 Mayo Foundation for Medical Education and Research.

    Al-Khateeb, Anas J; Al Khateeb, Jamal M

    2015-01-01

    The importance of psychosocial factors in the management of bronchial asthma has long been recognized. This paper offers a review of research published in the English language related to psychosocial aspects of bronchial asthma in Arab countries. Several databases (PubMed, Science Direct, Springer Link, ERIC, and PsychInfo) were searched using the following keywords: bronchial asthma, Arab countries, Algiers, Bahrain, Comoros, Djibouti, Egypt, Iraq, Jordan, Kuwait, Lebanon, Libya, Mauritania, Morocco, Oman, Palestine (West Bank, Gaza), Qatar, Saudi Arabia, Syria, Tunisia, Sudan, Somalia; United Arab Emirates, and Yemen. Thirty-two studies were conducted in 9 Arab countries. Almost all studies found were published in the last fourteen years with an apparent increasing rate in the last five years. In descending order, these studies addressed: knowledge of and attitudes toward asthma, quality of life, behavioral and emotional problems and factors related to academic achievement. The main results of the studies reviewed were: (a) physicians', school staff's, and parents' knowledge of and attitudes toward asthma were generally unsatisfactory, (b) in-service asthma education programs significantly impacted parent and staff knowledge and attitudes, and asthma management practices, (c) quality of life in children and adolescents was significantly adversely affected by asthma, (d) asthma was a common cause of school absenteeism, and had a significant negative impact on academic achievement of students, and (e) students with asthma had significantly higher rates of behavioral and emotional difficulties compared to students without asthma. The paper concludes with a discussion about the implications of these results and a call for further research in this area.

  15. Diagnosis of asthma - new theories.

    Science.gov (United States)

    Löwhagen, Olle

    2015-01-01

    Recent studies have shown a remarkably high frequency of poorly controlled asthma. Several reasons for this treatment failure have been discussed, however, the basic question of whether the diagnosis is always correct has not been considered. Follow-up studies have shown that in many patients asthma cannot be verified despite ongoing symptoms. Mechanisms other than bronchial obstruction may therefore be responsible. The current definition of asthma may also include symptoms that are related to mechanisms other than bronchial obstruction, the clinical hallmark of asthma. Based on a review of the four cornerstones of asthma - inflammation, hyperresponsiveness, bronchial obstruction and symptoms - the aim was to present some new aspects and suggestions related to the diagnosis of adult non-allergic asthma. Recent studies have indicated that "classic" asthma may sometimes be confused with asthma-like disorders such as airway sensory hyperreactivity, small airways disease, dysfunctional breathing, non-obstructive dyspnea, hyperventilation and vocal cord dysfunction. This confusion may be one explanation for the high proportion of misdiagnosis and treatment failure. The current diagnosis, focusing on bronchial obstruction, may be too "narrow". As there may be common mechanisms a broadening to include also non-obstructive disorders, forming an asthma syndrome, is suggested. Such broadening requires additional diagnostic steps, such as qualitative studies with analysis of reported symptoms, non-effort demanding methods for determining lung function, capsaicin test for revealing airway sensory hyperreactivity, careful evaluation of the therapeutic as well as diagnostic effect of corticosteroids and testing of suggested theories.

  16. Japanese Guideline for Childhood Asthma

    Directory of Open Access Journals (Sweden)

    Toshiyuki Nishimuta

    2011-01-01

    JAGL differs from the Global Initiative for Asthma Guideline (GINA in that the former emphasizes long-term management of childhood asthma based on asthma severity and early diagnosis and intervention at <2 years and 2–5 years of age. However, a management method, including step-up or step-down of long-term management agents based on the status of asthma symptoms, is easy to understand and thus JAGL is suitable for routine medical treatment. JAGL also introduced treatment and management using a control test for children, recommending treatment and management aimed at complete control through avoiding exacerbation factors and appropriate use of antiinflammatory agents.

  17. Diagnosis of asthma: diagnostic testing.

    Science.gov (United States)

    Brigham, Emily P; West, Natalie E

    2015-09-01

    Asthma is a heterogeneous disease, encompassing both atopic and non-atopic phenotypes. Diagnosis of asthma is based on the combined presence of typical symptoms and objective tests of lung function. Objective diagnostic testing consists of 2 components: (1) demonstration of airway obstruction, and (2) documentation of variability in degree of obstruction. A review of current guidelines and literature was performed regarding diagnostic testing for asthma. Spirometry with bronchodilator reversibility testing remains the mainstay of asthma diagnostic testing for children and adults. Repetition of the test over several time points may be necessary to confirm airway obstruction and variability thereof. Repeated peak flow measurement is relatively simple to implement in a clinical and home setting. Bronchial challenge testing is reserved for patients in whom the aforementioned testing has been unrevealing but clinical suspicion remains, though is associated with low specificity. Demonstration of eosinophilic inflammation, via fractional exhaled nitric oxide measurement, or atopy, may be supportive of atopic asthma, though diagnostic utility is limited particularly in nonatopic asthma. All efforts should be made to confirm the diagnosis of asthma in those who are being presumptively treated but have not had objective measurements of variability in the degree of obstruction. Multiple testing modalities are available for objective confirmation of airway obstruction and variability thereof, consistent with a diagnosis of asthma in the appropriate clinical context. Providers should be aware that both these characteristics may be present in other disease states, and may not be specific to a diagnosis of asthma. © 2015 ARS-AAOA, LLC.

  18. Parental mental health, childhood psychiatric disorders, and asthma attacks in island Puerto Rican youth.

    Ortega, Alexander N; Goodwin, Renee D; McQuaid, Elizabeth L; Canino, Glorisa

    2004-01-01

    Previous research documents an association of poor parental mental health with asthma in children. This study aims to determine whether the associations between parental mental health problems and childhood asthma attacks persist after controlling for childhood anxiety and depression and other confounding factors. A community household sample of youth ages 4 to 17 years and their primary caregivers from the US Commonwealth of Puerto Rico was studied to determine the associations between parental mental health and childhood asthma attacks. Regression models that predicted asthma attacks in youth controlled for parental mental health problems, childhood anxiety and depression, zone of residence, and parents' age, education, and perception of poverty. After adjusting for children's depressive and anxiety disorders as well as other important confounders, associations between parental depression, suicide attempts, ataque de nervios, and history of mental health treatment and asthma attacks in offspring, by parental report, persisted. Additionally, the frequency of parental mental health problems was associated with children's asthma attacks. Parents with mental health problems were more likely to report histories of asthma attacks in their children compared with parents without mental health problems in Puerto Rico. These associations were not attributable to internalizing disorders in youth but persisted independent of childhood psychopathology and other confounding factors. Clinicians and researchers should recognize the relations between poor parental mental health and childhood asthma and explore the potential role of family psychosocial and behavioral factors related to the manifestation of the disease.

  19. [The Chinese experts' consensus on the evaluation and management of asthma exacerbation].

    Science.gov (United States)

    2018-01-01

    Asthma exacerbations can do a lot of harm to the patients and consume large amounts of medical resources. This consensus is based on the domestic and foreign guidelines and literatures to standardize the evaluation and management of asthma exacerbations in China. Asthma exacerbations are characterized by a progressive increase in symptoms of shortness of breath, cough, wheezing or chest tightness and progressive decrease in lung function, and usually require modification of treatment. Recognizing risk factors and triggering factors of asthma exacerbations is helpful for the prevention and long-term management. Evaluation of asthma exacerbations is based on symptoms, lung function, and arterial blood gas. Management is stratified according to the severity of disease. Different regimens to treat asthma exacerbations are discussed in this consensus. Glucocorticoids should be used properly. Overuse of antibiotics should be avoided. Management of life-threatening asthma is discussed separately. Special attention should be paid in some special respects, such as asthma during peri-operation period, gestation period, and childhood. Diagnosis and management of complications are also of great significance and are discussed in details.

  20. Acute bronchial asthma

    2007-04-01

    Full Text Available Asthma is one of the main causes of morbidity worldwide. It affects some 300 million individuals and has risen over the past 20 years, especially in the paediatric population. Asthma is a chronic inflammation of the airways, subject to periodic exacerbations, characterised by coughing and progressive dyspnoea. Clinical conditions may vary greatly, ranging from moderate exacerbation with an increase in nocturnal awakening and a less than 20% reduction in the flow peak, through to severe respiratory insufficiency that requires immediate intubation of the airways. Pharmacological treatment envisages a step approach that aims to obtain and maintain control over the symptoms, taking into consideration the effectiveness of the treatment available, potential side effects and cost. β2-agonists and corticosteroids are the drugs of election for both maintenance therapy and for treating exacerbations. Other therapeutic devices may prove useful in particular cases. One fundamental key point in treatment over time is the cooperation between patient and attending doctor. The latest review of the Global Initiative for Asthma (GINA guidelines was published in 2006.

    Salazar Cabrera, A N; Berrón Pérez, R; Ortega Martell, J A; Onuma Takane, E

    1996-01-01

    We report a male with history of recurrent infections (recurrent oral aphtous disease [ROAD], middle ear infections and pharyngo amigdalitis) every 3 weeks since he was 7 months old. At the age of 3 years cyclic neutropenia was diagnosed with cyclic fall in the total neutrophil count in blood smear every 21 days and prophylactic antimicrobial therapy was indicated. Episodic events every 3 weeks of acute asthma and allergic rhinitis were detected at the age of 6 years old and specific immunotherapy to Bermuda grass was given during 3 years with markedly improvement in his allergic condition but not in the ROAD. He came back until the age of 16 with episodic acute asthma and ROAD. The total neutrophil count failed to 0 every 21 days and surprisingly the total eosinophil count increased up to 2,000 at the same time, with elevation of serum IgE (412 Ul/mL). Specific immunotherapy to D.pt. and Aller.a. and therapy with timomodulin was indicated. After 3 months we observed clinical improvement in the asthmatic condition and the ROAD disappeared, but the total neutrophil count did not improve. We present this case as a rare association between 2 diseases with probably no etiological relationship but may be physiopatological that could help to understand more the pathogenesis of asthma.

  2. Asthma and PM10

    Directory of Open Access Journals (Sweden)

    Gilmour M Ian

    2000-07-01

    Full Text Available Abstract PM10 (the mass of particles present in the air having a 50% cutoff for particles with an aerodynamic diameter of 10 μm is the standard measure of particulate air pollution used worldwide. Epidemiological studies suggest that asthma symptoms can be worsened by increases in the levels of PM10. Epidemiological evidence at present indicates that PM10 increases do not raise the chances of initial sensitisation and induction of disease, although further research is warranted. PM10 is a complex mixture of particle types and has many components and there is no general agreement regarding which component(s could lead to exacerbations of asthma. However pro-inflammatory effects of transition metals, hydrocarbons, ultrafine particles and endotoxin, all present to varying degrees in PM10, could be important. An understanding of the role of the different components of PM10 in exacerbating asthma is essential before proper risk assessment can be undertaken leading to advice on risk management for the many asthmatics who are exposed to air pollution particles.

  6. Producing and Recognizing Analogical Relations

    Lipkens, Regina; Hayes, Steven C

    2009-01-01

    Analogical reasoning is an important component of intelligent behavior, and a key test of any approach to human language and cognition. Only a limited amount of empirical work has been conducted from a behavior analytic point of view, most of that within Relational Frame Theory (RFT), which views analogy as a matter of deriving relations among relations. The present series of four studies expands previous work by exploring the applicability of this model of analogy to topography-based rather than merely selection-based responses and by extending the work into additional relations, including nonsymmetrical ones. In each of the four studies participants pretrained in contextual control over nonarbitrary stimulus relations of sameness and opposition, or of sameness, smaller than, and larger than, learned arbitrary stimulus relations in the presence of these relational cues and derived analogies involving directly trained relations and derived relations of mutual and combinatorial entailment, measured using a variety of productive and selection-based measures. In Experiment 1 participants successfully recognized analogies among stimulus networks containing same and opposite relations; in Experiment 2 analogy was successfully used to extend derived relations to pairs of novel stimuli; in Experiment 3 the procedure used in Experiment 1 was extended to nonsymmetrical comparative relations; in Experiment 4 the procedure used in Experiment 2 was extended to nonsymmetrical comparative relations. Although not every participant showed the effects predicted, overall the procedures occasioned relational responses consistent with an RFT account that have not yet been demonstrated in a behavior-analytic laboratory setting, including productive responding on the basis of analogies.

    Environmental exposures have been recognized as critical in the initiation and exacerbation of asthma, one of the most common chronic childhood diseases. The National Institute of Allergy and Infectious Diseases; National Institute of Environmental Health Sciences; National Heart, Lung, and Blood Institute; and Merck Childhood Asthma Network sponsored a joint workshop to discuss the current state of science with respect to the indoor environment and its effects on the development and morbidity of childhood asthma. The workshop included US and international experts with backgrounds in allergy/allergens, immunology, asthma, environmental health, environmental exposures and pollutants, epidemiology, public health, and bioinformatics. Workshop participants provided new insights into the biologic properties of indoor exposures, indoor exposure assessment, and exposure reduction techniques. This informed a primary focus of the workshop: to critically review trials and research relevant to the prevention or control of asthma through environmental intervention. The participants identified important limitations and gaps in scientific methodologies and knowledge and proposed and prioritized areas for future research. The group reviewed socioeconomic and structural challenges to changing environmental exposure and offered recommendations for creative study design to overcome these challenges in trials to improve asthma management. The recommendations of this workshop can serve as guidance for future research in the study of the indoor environment and on environmental interventions as they pertain to the prevention and management of asthma and airway allergies.

    Briones, Kristi; Lustik, Faith; LaLone, Joel

    2010-11-01

    Many parents and caregivers do not recognize the symptoms of asthma in children, and consequently children may not receive the appropriate diagnosis and treatment for this potentially fatal disease. This article describes how Steps to a HealthierNY used social marketing strategies to design a media campaign called "Could It Be Asthma?" to educate parents and caregivers about the symptoms of asthma. The campaign used television advertising, brochures, and posters to educate parents and caregivers in rural Jefferson County, New York, about asthma symptoms. The campaign ran in March and April 2005. A follow-up survey was conducted among 756 parents and caregivers in collaboration with four local pediatricians' offices. Results showed that approximately 60% of participants were familiar with "Could It Be Asthma?" Of those participants, approximately 68% indicated that the ads had a positive impact and 46% indicated that they had learned the symptoms of asthma. The campaign and survey were repeated in the fall of 2005. Results were consistent, with a significant increase in the percentage of people who were familiar with the campaign. This social marketing campaign was successful in reaching parents in a rural community with important educational messages; similar strategies should be considered in educating the public about asthma and other health issues.

    Previous research has suggested an inverse relationship between T-helper 2-related atopic disorders, such as asthma, and T-helper 1-related autoimmune diseases. One controversial hypothesis postulates that asthma provides a protective effect for the development of autoimmune-related disorders. To assess the rate of newly diagnosed autoimmune disorders in a large cohort of young adults. Using cross-sectional data from the Israeli Defense Force database, the authors analyzed the prevalence of autoimmune disorders in asthmatic and nonasthmatic military personnel between 1980 and 2003. A follow-up study traced newly diagnosed autoimmune disorders among asthmatic and nonasthmatic individuals from the time of enrollment in military service until discharge (22 and 36 months for women and men, respectively). General community. 307,367 male and 181,474 female soldiers in compulsory military service who were between 18 and 21 years of age. Cases of type 1 diabetes mellitus, vasculitis, immune thrombocytopenic purpura, inflammatory bowel disease, rheumatoid arthritis, and the antiphospholipid syndrome. Of 488,841 participants at enrollment, significantly more women than men had autoimmune disorders. Compared with asthmatic women, nonasthmatic women had a significantly higher prevalence of all autoimmune disorders except for the antiphospholipid syndrome. Type 1 diabetes mellitus, vasculitis, and rheumatoid arthritis were less prevalent in men with asthma than in those without. During the follow-up period, vasculitis and rheumatoid arthritis were more frequently diagnosed in nonasthmatic persons of both sexes. There was a significantly higher incidence of immune thrombocytopenic purpura, inflammatory bowel disease, and the antiphospholipid syndrome in nonasthmatic women and a statistically significantly higher incidence of type 1 diabetes mellitus in nonasthmatic men. The study was limited to a population of young military recruits; therefore, its findings are not necessarily

    A first step in primary disease prevention is identifying common, modifiable risk factors that contribute to a significant proportion of disease development. Infant respiratory viral infection and childhood asthma are the most common acute and chronic diseases of childhood, respectively. Common clinical features and links between these diseases have long been recognized, with early-life respiratory syncytial virus (RSV) and rhinovirus (RV) lower respiratory tract infections (LRTIs) being strongly associated with increased asthma risk. However, there has long been debate over the role of these respiratory viruses in asthma inception. In this article, we systematically review the evidence linking early-life RSV and RV LRTIs with asthma inception and whether they could therefore be targets for primary prevention efforts.

    Despite the increasing attention to the relationship between asthma and work exposures, occupational asthma remains underrecognized and its population burden underestimated. This may be due, in part, to the fact that traditional approaches to studying asthma in populations cannot adequately take into account the healthy worker effect (HWE). The HWE is the potential bias caused by the phenomenon that sicker individuals may choose work environments in which exposures are low; they may be excluded from being hired; or once hired, they may seek transfer to less exposed jobs or leave work. This article demonstrates that population- and workplace-based asthma studies are particularly subject to HWE bias, which leads to underestimates of relative risks. Our objective is to describe the HWE as it relates to asthma research, and to discuss the significance of taking HWE bias into account in designing and interpreting asthma studies. We also discuss the importance of understanding HWE bias for public health practitioners and for clinicians. Finally, we emphasize the timeliness of this review in light of the many longitudinal "child to young adult" asthma cohort studies currently underway. These prospective studies will soon provide an ideal opportunity to examine the impact of early workplace environments on asthma in young adults. We urge occupational and childhood asthma epidemiologists collaborate to ensure that this opportunity is not lost.

    Background Severe asthma occurs more often in older adult patients. We hypothesized that the greater risk for severe asthma in older individuals is due to aging, and is independent of asthma duration. Methods This is a cross-sectional study of prospectively collected data from adult participants (N=1130; 454 with severe asthma) enrolled from 2002 – 2011 in the Severe Asthma Research Program. Results The association between age and the probability of severe asthma, which was performed by applying a Locally Weighted Scatterplot Smoother, revealed an inflection point at age 45 for risk of severe asthma. The probability of severe asthma increased with each year of life until 45 years and thereafter increased at a much slower rate. Asthma duration also increased the probability of severe asthma but had less effect than aging. After adjustment for most comorbidities of aging and for asthma duration using logistic regression, asthmatics older than 45 maintained the greater probability of severe asthma [OR: 2.73 (95 CI: 1.96; 3.81)]. After 45, the age-related risk of severe asthma continued to increase in men, but not in women. Conclusions Overall, the impact of age and asthma duration on risk for asthma severity in men and women is greatest over times of 18-45 years of age; age has a greater effect than asthma duration on risk of severe asthma.

    Full Text Available The Saudi Initiative for Asthma (SINA provides up-to-date guidelines for healthcare workers managing patients with asthma. SINA was developed by a panel of Saudi experts with respectable academic backgrounds and long-standing experience in the field. SINA is founded on the latest available evidence, local literature, and knowledge of the current setting in Saudi Arabia. Emphasis is placed on understanding the epidemiology, pathophysiology, medications, and clinical presentation. SINA elaborates on the development of patient-doctor partnership, self-management, and control of precipitating factors. Approaches to asthma treatment in SINA are based on disease control by the utilization of Asthma Control Test for the initiation and adjustment of asthma treatment. This guideline is established for the treatment of asthma in both children and adults, with special attention to children 5 years and younger. It is expected that the implementation of these guidelines for treating asthma will lead to better asthma control and decrease patient utilization of the health care system.

    To analyze the knowledge of asthma and its management in Spanish school teachers using the Newcastle Asthma Questionnaire (NAKQ). Descriptive, observational prevalence study, using a self-report questionnaire on knowledge about childhood asthma and its management by teachers in pre-school, primary, and secondary schools in nine Spanish cities. Age, sex, academic training, teaching experience, courses in which they taught, and personal and family history of asthma, were collected from each teacher. For knowledge determination, the validated Spanish version of the NAKQ was used. A total of 208 centers participated, including 7,494 teachers. The questionnaire was completed by 4,679 teachers (62.4%). The mean score of correct responses was 16.0 ± 4.8 points out of 31 (median = 17, range: 0-30). Only 6.8% of teachers were capable of pointing out the three main symptoms of the disease; 1.5% knew the triggering factors of an asthma attack; 8.6% knew two medicines useful during an asthma attack; 32.7% knew that inhaled medications had less side effects than pills, and only 3.8% knew of ways to prevent asthma attacks during exercise. In the multivariate analysis, variables significantly associated with a higher questionnaire score were a "lower age" (Beta coefficient = -0.09), "male gender" (Beta = 0.77), "being asthmatic" (Beta = 2.10), or "having close relatives with asthma" (Beta = 1.36) and "teaching in a private school" (Beta = 0.66) or in "compulsory secondary education" (Beta = 0.59). Teachers have a low level of knowledge about asthma, with an important limitation in some aspects of the disease. They should be trained to recognize the main symptoms of the disease, on how to act in the event of symptoms, and the early identification of situations in which the pupils require health care assistance.

    Asthma is common among pregnant women, and the incidence of asthma exacerbations during pregnancy is high. This literature review provides an overview of the impact of exacerbations of asthma during pregnancy on pregnancy-related complications. The majority of published retrospective studies reveal...... that asthma exacerbations during pregnancy increase the risk of pre-eclampsia, gestational diabetes, placental abruption and placenta praevia. Furthermore, these women also have higher risk for breech presentation, haemorrhage, pulmonary embolism, caesarean delivery, maternal admission to the intensive care...... to these outcomes. In conclusion, asthma exacerbations during pregnancy are associated with complications of pregnancy, labour and delivery. Prevention of exacerbations is essential to reduce the risk of complications and poor outcome....

  1. Predictive Biomarkers for Asthma Therapy.

    Medrek, Sarah K; Parulekar, Amit D; Hanania, Nicola A

    2017-09-19

    Asthma is a heterogeneous disease characterized by multiple phenotypes. Treatment of patients with severe disease can be challenging. Predictive biomarkers are measurable characteristics that reflect the underlying pathophysiology of asthma and can identify patients that are likely to respond to a given therapy. This review discusses current knowledge regarding predictive biomarkers in asthma. Recent trials evaluating biologic therapies targeting IgE, IL-5, IL-13, and IL-4 have utilized predictive biomarkers to identify patients who might benefit from treatment. Other work has suggested that using composite biomarkers may offer enhanced predictive capabilities in tailoring asthma therapy. Multiple biomarkers including sputum eosinophil count, blood eosinophil count, fractional concentration of nitric oxide in exhaled breath (FeNO), and serum periostin have been used to identify which patients will respond to targeted asthma medications. Further work is needed to integrate predictive biomarkers into clinical practice.

    2016-01-01

    The term asthma encompasses a disease spectrum with mild to very severe disease phenotypes whose traditional common characteristic is reversible airflow limitation. Unlike milder disease, severe asthma is poorly controlled by the current standard of care. Ongoing studies using advanced molecular and immunological tools along with improved clinical classification show that severe asthma does not identify a specific patient phenotype, but rather includes patients with constant medical needs, whose pathobiologic and clinical characteristics vary widely. Accordingly, in recent clinical trials, therapies guided by specific patient characteristics have had better outcomes than previous therapies directed to any subject with a diagnosis of severe asthma. However, there are still significant gaps in our understanding of the full scope of this disease that hinder the development of effective treatments for all severe asthmatics. In this Review, we discuss our current state of knowledge regarding severe asthma, highlighting different molecular and immunological pathways that can be targeted for future therapeutic development.

    The association between asthma and obesity is well-described, but not straightforward, and according to current guidelines asthma control is more difficult to achieve in obese patients. The currently available studies evaluating response to pharmacological asthma therapy in obese patients show...... that these patients have an altered, in general less favorable, response to both reliever and controller medication compared to normal weight patients. However, at present, the limited available evidence precludes evidence-based recommendations. The 'obesity-related asthma' phenotype has different characteristics......, including association with atopy and type of airway inflammation, compared to 'classic' asthma. Furthermore, weight loss in patients with this phenotype leads to an improvement in symptoms, lung function, and airway responsiveness, as well as a reduction in medication utilization and hospital admissions...

  4. Root tips moving through soil

    Curlango-Rivera, Gilberto

    2011-01-01

    Root elongation occurs by the generation of new cells from meristematic tissue within the apical 1–2 mm region of root tips. Therefore penetration of the soil environment is carried out by newly synthesized plant tissue, whose cells are inherently vulnerable to invasion by pathogens. This conundrum, on its face, would seem to reflect an intolerable risk to the successful establishment of root systems needed for plant life. Yet root tip regions housing the meristematic tissues repeatedly have been found to be free of microbial infection and colonization. Even when spore germination, chemotaxis, and/or growth of pathogens are stimulated by signals from the root tip, the underlying root tissue can escape invasion. Recent insights into the functions of root border cells, and the regulation of their production by transient exposure to external signals, may shed light on long-standing observations. PMID:21455030

  5. Crack tip stress and strain

    International Nuclear Information System (INIS)

    Francois, D.

    1975-01-01

    The study of potential energy variations in a loaded elastic solid containing a crack leads to determination of the crack driving force G. Generalization of this concept to cases other than linear elasticity leads to definition of the integral J. In a linear solid, the crack tip stress field is characterized by a single parameter: the stress-intensity factor K. When the crack tip plastic zone size is confined to the elastic singularity J=G, it is possible to establish relationship between these parameters and plastic strain (and in particular the crack tip opening displacement delta). The stress increases because of the triaxiality effect. This overload rises with increasing strain hardening. When the plastic zone size expands, using certain hypotheses, delta can be calculated. The plastic strain intensity is exclusively dependent on parameter J [fr

    We report on the first example of a "meta-tip" configuration that integrates a metasurface on the tip of an optical fiber. Our proposed design is based on an inverted-Babinet plasmonic metasurface obtained by patterning (via focused ion beam) a thin gold film deposited on the tip of an optical fiber, so as to realize an array of rectangular aperture nanoantennas with spatially modulated sizes. By properly tuning the resonances of the aperture nanoantennas, abrupt variations can be impressed in the field wavefront and polarization. We fabricated and characterized several proof-of-principle prototypes operating an near-infrared wavelengths, and implementing the beam-steering (with various angles) of the cross-polarized component, as well as the excitation of surface waves. Our results pave the way to the integration of the exceptional field-manipulation capabilities enabled by metasurfaces with the versatility and ubiquity of fiber-optics technological platforms.

  8. Airway remodeling and its reversibility in equine asthma

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available Despite effective therapies for controlling its clinical manifestations, human asthma remains an incurable disease. It is now recognized that inflammation induced structural changes (remodeling of the airways are responsible for the progressive loss of lung function in asthmatic patients. However, the peripheral airways, where most of the remodeling occurs in severe asthmatic patients, cannot be safely sampled in humans, and therefore, little is known of the effects of current therapies at reversing the established asthmatic remodeling, especially those occurring in the peripheral airways. Animal models have been studied to unravel etiological, immunopathological, and genetic attributes leading to asthma. However, experiments in which the disease is artificially induced have been shown to have limited translational potential for humans. To the contrary, horses naturally suffer from an asthma-like condition which shares marked similarities with human asthma making this model unique to investigate the kinetics, reversibility, as well as the physiological consequences of tissue remodeling (Bullone and Lavoie 2015. We reported an increased deposition of smooth muscle, collagen and elastic fibers in the peripheral airways of affected horses, which was correlated with the lung function (Herszberg et al., 2006; Setlakwe et al., 2014. The airway subepithelial collagen depositions were almost completely reversed with 6 to 12 months of treatment with either antigen avoidance or inhaled corticosteroids (ICS administration, and there was a modest (30% on average decrease in airway smooth muscle (Leclere et al., 2011. A recent study also found that ICS combined with long-acting ß2-agonists drugs (LABA and ICS monotherapy similarly induced a 30% decrease of the airway smooth muscle mass at 3 months (Buollone, 2017. However, only ICS/LABA and antigen avoidance decreased airway luminal neutrophilia. The findings indicate the enhance therapeutic effect of ICS

    2005-01-01

    Limitations in asthma prevalence studies and difficulties in diagnosing pediatric asthma lead to uncertainty over the full extent of mild persistent asthma in children and adolescents. Although recent surveys have reported that the majority of pediatric patients with asthma in the United States...... and Europe have symptoms consistent with mild disease, these surveys have limitations in design. Thus, the true prevalence of mild asthma remains unknown. It is unclear whether children with mild persistent asthma progress to more severe asthma, but the risk of severe asthma exacerbations seems...... to be unrelated to the symptom severity. Clinical studies restricted to pediatric patients with mild asthma are limited, but available data do suggest substantial morbidity of mild persistent asthma in this population and support inhaled corticosteroid intervention. There is a need for further investigation...

    2015-01-01

    Asthma self-management education improves asthma-related outcomes. We conducted this analysis to evaluate variation in the percentages of adults with active asthma reporting components of asthma self-management education by age at asthma onset. Data from 2011 to 2012 Asthma Call-back Surveys were used to estimate percentages of adults with active asthma reporting six components of asthma self-management education. Components of asthma self-management education include having been taught to what to do during an asthma attack and receiving an asthma action plan. Differences in the percentages of adults reporting each component and the average number of components reported across categories of age at asthma onset were estimated using linear regression, adjusted for age, education, race/ethnicity, sex, smoking status, and years since asthma onset. Overall, an estimated 76.4% of adults with active asthma were taught what to do during an asthma attack and 28.7% reported receiving an asthma action plan. Percentages reporting each asthma self-management education component declined with increasing age at asthma onset. Compared with the referent group of adults whose asthma onset occurred at 5-14 years of age, the percentage of adults reporting being taught what to do during an asthma attack was 10% lower among those whose asthma onset occurred at 65-93 years of age (95% CI: -18.0, -2.5) and the average number of components reported decreased monotonically across categories of age at asthma onset of 35 years and older. Among adults with active asthma, reports of asthma self-management education decline with increasing age at asthma onset.

  14. Asthma and dualism.

    Science.gov (United States)

    Paley, J

    2000-06-01

    The rejection of Cartesian dualism can be taken to imply that the mind is implicated in health and illness to a greater degree than conventional medicine would suggest. Surprisingly, however, there appears to be a train of thought in antidualist nursing theory which takes the opposite view. This paper looks closely at an interesting example of antidualist thinking - an article in which Benner and her colleagues comment on the ways in which people with asthma make sense of their condition - and concludes that it places unduly stringent and arbitrary limits on the mind's role. It then asks how antidualism can lead to such a dogmatic rejection of the idea that states of the body are clinically influenced by states of mind. The answer to this question is that Benner assimilates very different philosophical theories into the same 'tradition'. On this occasion, she has combined Descartes, Kant and the Platonist ascetics into a single package, misleadingly labelled 'Cartesianism', and this move accounts for her unexpected views on the relation between mind and body in asthma.

  15. Respiratory reviews in asthma 2013.

    Kim, Tae-Hyung

    2014-03-01

    From January 2012 up until March 2013, many articles with huge clinical importance in asthma were published based on large numbered clinical trials or meta-analysis. The main subjects of these studies were the new therapeutic plan based on the asthma phenotype or efficacy along with the safety issues regarding the current treatment guidelines. For efficacy and safety issues, inhaled corticosteroid tapering strategy or continued long-acting beta agonists use was the major concern. As new therapeutic trials, monoclonal antibodies or macrolide antibiotics based on inflammatory phenotypes have been under investigation, with promising preliminary results. There were other issues on the disease susceptibility or genetic background of asthma, particularly for the "severe asthma" phenotype. In the era of genome and pharmacogenetics, there have been extensive studies to identify susceptible candidate genes based on the results of genome wide association studies (GWAS). However, for severe asthma, which is where most of the mortality or medical costs develop, it is very unclear. Moreover, there have been some efforts to find important genetic information in order to predict the possible disease progression, but with few significant results up until now. In conclusion, there are new on-going aspects in the phenotypic classification of asthma and therapeutic strategy according to the phenotypic variations. With more pharmacogenomic information and clear identification of the "severe asthma" group even before disease progression from GWAS data, more adequate and individualized therapeutic strategy could be realized in the future.

  16. Diet and asthma: an update.

    Science.gov (United States)

    Han, Yueh-Ying; Forno, Erick; Holguin, Fernando; Celedón, Juan C

    2015-08-01

    Our objective was to provide an overview and discussion of recent experimental studies, epidemiologic studies, and clinical trials of diet and asthma. We focus on dietary sources and vitamins with antioxidant properties [vitamins (A, C, and E), folate, and omega-3 and omega-6 polyunsaturated fatty acids (n-3 and n-6 PUFAs)]. Current evidence does not support the use of vitamin A, vitamin C, vitamin E, or PUFAs for the prevention or treatment of asthma or allergies. Current guidelines for prenatal use of folate to prevent neural tube defects should be followed, as there is no evidence of major effects of this practice on asthma or allergies. Consumption of a balanced diet that is rich in sources of antioxidants (e.g. fruits and vegetables) may be beneficial in the primary prevention of asthma. None of the vitamins or nutrients examined is consistently associated with asthma or allergies. In some cases, further studies of the effects of a vitamin or nutrient on specific asthma phenotypes (e.g. vitamin C to prevent viral-induced exacerbations) are warranted. Clinical trials of 'whole diet' interventions to prevent asthma are advisable on the basis of existing evidence.

  17. Childhood asthma-predictive phenotype.

    2014-01-01

    Wheezing is a fairly common symptom in early childhood, but only some of these toddlers will experience continued wheezing symptoms in later childhood. The definition of the asthma-predictive phenotype is in children with frequent, recurrent wheezing in early life who have risk factors associated with the continuation of asthma symptoms in later life. Several asthma-predictive phenotypes were developed retrospectively based on large, longitudinal cohort studies; however, it can be difficult to differentiate these phenotypes clinically as the expression of symptoms, and risk factors can change with time. Genetic, environmental, developmental, and host factors and their interactions may contribute to the development, severity, and persistence of the asthma phenotype over time. Key characteristics that distinguish the childhood asthma-predictive phenotype include the following: male sex; a history of wheezing, with lower respiratory tract infections; history of parental asthma; history of atopic dermatitis; eosinophilia; early sensitization to food or aeroallergens; or lower lung function in early life.

    2013-09-23

    Childhood obesity and asthma are on the rise in the U.S. Clinical and epidemiological data suggest a link between the two, in which overweight and obese children are at higher risk for asthma. Prevention of childhood obesity is preferred over treatment, however, in order to be receptive to messages, parents must perceive that their child is overweight. Many parents do not accurately assess their child's weight status. Herein, the relation between parental perceptions of child weight status, observed body mass index (BMI) percentiles, and a measure of child feeding practices were explored in the context of asthma, food allergy, or both. Out of the children with asthma or food allergy that were classified as overweight/obese by BMI percentiles, 93% were not perceived as overweight/obese by the parent. Mean scores for concern about child weight were higher in children with both asthma and food allergy than either condition alone, yet there were no significant differences among the groups in terms of pressure to eat and restrictive feeding practices. In summary, parents of children with asthma or food allergy were less likely to recognize their child's overweight/obese status and their feeding practices did not differ from those without asthma and food allergy.

  10. Treatment of psychological factors in a child with difficult asthma: a case report.

    Science.gov (United States)

    Anbar, Ran D; Sachdeva, Shagun

    2011-07-01

    Difficult asthma is defined as the persistence of asthma symptoms, abnormal pulmonary function showing airway obstruction, and continued requirement for short-acting bronchodilator therapy, despite adequate treatment with inhaled corticosteroids. It calls for a thorough evaluation of the patient to look into alternate and complicating diagnoses. The authors report a case of a 9-year-old patient with difficult asthma who failed to respond to conventional therapy. Although it was recognized that he had a number of potential medical complicating factors including allergies, chronic sinusitis, and gastroesophageal reflux, a psychological intervention using hypnosis ultimately appeared to help alleviate his symptoms completely. Thus, psychological evaluation and intervention should be considered early in the course of management of a patient with difficult asthma, because it may help avoid time-consuming and expensive investigations of potential complicating factors, and it may yield rapid improvement in the patient's clinical condition.

    2012-11-01

    Full Text Available Abstract Background Apps have been enthusiastically adopted by the general public. They are increasingly recognized by policy-makers as a potential medium for supporting self-management of long-term conditions. We assessed the degree to which current smartphone and tablet apps for people with asthma offer content and tools of appropriate quality to support asthma self-management. Methods We adapted systematic review methodology to the assessment of apps. We identified English-language asthma apps for all ages through a systematic search of official app stores. We systematically assessed app content using criteria derived from international guidelines and systematic review of strategies for asthma self-management. We covered three domains: comprehensiveness of asthma information, consistency of advice with evidence and compliance with health information best practice principles. Results We identified 103 apps for asthma in English, of which 56 were sources of information about the condition and 47 provided tools for the management of asthma. No apps offered both types of functionality. Only three information apps approached our definition of comprehensiveness of information about asthma. No apps provided advice on lay management of acute asthma that included details of appropriate reliever medication use. In 32 of 72 instances, apps made unequivocal recommendations about strategies for asthma control or prophylaxis that were unsupported by current evidence. Although 90% of apps stated a clear purpose, compliance with other best practice principles for health information was variable. Contact details were located for 55%, funding source for 18% and confidentiality policy for 17%. Conclusions No apps for people with asthma combined reliable, comprehensive information about the condition with supportive tools for self-management. Healthcare professionals considering recommending apps to patients as part of asthma self-management should exercise

    2018-01-01

    Full Text Available Physical activity can reduce symptoms and improve wellbeing in people who have asthma, and organized sport is one way for children and youth with asthma to engage in exercise. While asthmatic youth may experience a number of barriers to sport participation, healthy physical and social sport environments supported by coaches can help asthmatic youth athletes maintain long-term engagement in activity. This paper reports results of an assessment of an online coach education tool related to air quality, physical activity, and allergic disease (e.g., asthma. Focus groups with youth team sport coaches in southern Ontario (n=12 participants were conducted to explore how users experience the module and short- and medium-term outcomes of implementation. Although coaches perceive the module as relevant, it is considered less valuable in certain contexts (e.g., indoor environments or when compared with other coach education (e.g., tactical. Although broad asthma management behaviours (e.g., athlete medical forms were recognized, specific module-identified prevention and management techniques (e.g., the Air Quality Health Index were less frequently described. Ensuring environment and health coach education emphasizes athlete performance while reducing risk is critical to promoting module application and providing safe and enjoyable youth team sport spaces.

  14. Milk consumption and mucus production in children with asthma.

    Science.gov (United States)

    Thiara, Gurkaran; Goldman, Ran D

    2012-02-01

    Many parents of children with asthma are becoming increasingly reluctant to add milk to their children's diet because they believe it will worsen their children's asthma owing to increased mucus secretion. Recognizing the importance of milk as part of a healthy diet in supporting growth and calcium consumption, is it advisable to restrict milk in the diet? Dating back to the 12th century, milk has been proscribed for patients with asthma. However, to this very date studies have not been able to provide a definitive link for this recommendation. As there is a need for more conclusive evidence to determine the effect of milk among children with asthma and further understanding of mechanisms involved in mucus production, milk should not be eliminated or restricted. Health Canada recommends 2 servings of milk (0.5 L) a day for children 2 to 8 years of age and 3 to 4 servings of milk a day (0.75 to 1 L) for children 9 to 13 years of age for unrestricted healthy development.

  15. Work-related asthma, financial barriers to asthma care, and adverse asthma outcomes: asthma call-back survey, 37 states and District of Columbia, 2006 to 2008.

    2011-12-01

    Proper asthma management and control depend on patients having affordable access to healthcare yet financial barriers to asthma care are common. To examine associations of work-related asthma (WRA) with financial barriers to asthma care and adverse asthma outcomes. Cross-sectional, random-digit-dial survey conducted in 37 states and District of Columbia. A total of 27,927 ever-employed adults aged ≥18 years with current asthma. Prevalence ratios (PR) for the associations of WRA with financial barriers to asthma care and of WRA with adverse asthma outcomes stratified by financial barriers. Persons with WRA were significantly more likely than those with non-WRA to have at least 1 financial barrier to asthma care [PR, 1.66; 95% confidence interval (CI), 1.43-1.92]. Individuals with WRA were more likely to experience adverse asthma outcomes such as asthma attack (PR, 1.31; 95% CI, 1.22-1.40), urgent treatment for worsening asthma (PR, 1.57; 95% CI, 1.39-1.78), asthma-related emergency room visit (PR, 1.69; 95% CI, 1.41-2.03), and very poorly controlled asthma (PR, 1.54; 95% CI: 1.36-1.75). After stratifying for financial barriers to asthma care, the associations did not change. Financial barriers to asthma care should be considered in asthma management, and individuals with WRA are more likely to experience financial barriers. However, individuals with WRA are more likely to experience adverse asthma outcomes than individuals with non-WRA, regardless of financial barriers. Additional studies are needed to identify medical, behavioral, occupational, or environmental factors associated with adverse asthma outcomes among individuals with WRA.

    The aim of this study was to identify a possible association between the assessment of clinical asthma control using the Asthma Control Test (ACT) and the Global Initiative for Asthma (GINA) classification and to perform comparisons with values of spirometry. Through this cross-sectional study, 103 pregnant women with asthma were assessed in the period from October 2010 to October 2013 in the asthma pregnancy clinic at the Clinical Hospital of the Federal University of Pernambuco. Questionnaires concerning the level of asthma control were administered using the Global Initiative for Asthma classification, the Asthma Control Test validated for asthmatic expectant mothers and spirometry; all three methods of assessing asthma control were performed during the same visit between the twenty-first and twenty-seventh weeks of pregnancy. There was a significant association between clinical asthma control assessment using the Asthma Control Test and the Global Initiative for Asthma classification (pspirometry. This study shows that both the Global Initiative for Asthma classification and the Asthma Control Test can be used for asthmatic expectant mothers to assess the clinical control of asthma, especially at the end of the second trimester, which is assumed to be the period of worsening asthma exacerbations during pregnancy. We highlight the importance of the Asthma Control Test as a subjective instrument with easy application, easy interpretation and good reproducibility that does not require spirometry to assess the level of asthma control and can be used in the primary care of asthmatic expectant mothers.

    Utilizing an array of three hydrophones, individual cavitation bursts in a tip vortex could be located. Theoretically, four hydrophones are necessary. Hence the data from three hydrophones are supplemented with photographic observation of the cavitating tip vortex. The cavitation sound sources are found to be localized to within one base chord length from the hydrofoil tip. This appears to correspond to the region of initial tip vortex roll-up. A more extensive study with a four sensor array is now in progress

    Radiofrequency (RF) guide wires have been applied to cardiac interventions, recanalization of central venous thromboses, and to cross biliary occlusions. Herein, the use of a RF wire technique to revise chronically occluded transjugular intrahepatic portosystemic shunts (TIPS) is described. In both cases, conventional TIPS revision techniques failed to revise the chronically thrombosed TIPS. RF wire recanalization was successfully performed through each of the chronically thrombosed TIPS, demonstrating initial safety and feasibility in this application.

  4. The poorly explored impact of uncontrolled asthma

    DEFF Research Database (Denmark)

    O'Byrne, Paul M; Pedersen, Søren; Schatz, Michael

    2013-01-01

    The goal of asthma management is to achieve disease control; however, despite the availability of effective and safe medications, for many patients asthma remains uncontrolled. One reason for this is the fear of long-term side effects from the regular use of inhaled corticosteroids (ICSs). Adverse...... effects of poorly controlled asthma (for example, obesity, pneumonia, and risks to the fetus) can be perceived as side effects of ICSs. Poorly controlled asthma adversely affects children's cardiovascular fitness, while children with well-controlled asthma perform at the same level as their peers....... Children with uncontrolled asthma also have a higher frequency of obesity than children with controlled asthma. Stress can affect asthma control, and children with poorly controlled asthma are more likely to have learning disabilities compared with those with good control. In adults, focused attention...

    Ardern, K D; Ram, F S

    2001-01-01

    Tartrazine is the best known and one of the most commonly used food additives. Food colorants are also used in many medications as well as foods. There has been conflicting evidence as to whether tartrazine causes exacerbations of asthma with some studies finding a positive association especially in individuals with cross-sensitivity to aspirin. To assess the overall effect of tartrazine (exclusion or challenge) in the management of asthma. A search was carried out using the Cochrane Airways Group specialised register. Bibliographies of each RCT was searched for additional papers. Authors of identified RCTs were contacted for further information for their trials and details of other studies. RCTs of oral administration of tartrazine (as a challenge) versus placebo or dietary avoidance of tartrazine versus normal diet were considered. Studies which focused upon allergic asthma, were also included. Studies of tartrazine exclusion for other allergic conditions such as hay fever, allergic rhinitis and eczema were only considered if the results for subjects with asthma were separately identified. Trials could be in either adults or children with asthma or allergic asthma (e.g. sensitivity to aspirin or food items known to contain tartrazine). Study quality was assessed and data abstracted by two reviewers independently. Outcomes were analysed using RevMan 4.1.1. Ninety abstracts were found, of which 18 were potentially relevant. Six met the inclusion criteria, but only three presented results in a format that permitted analysis and none could be combined in a meta-analysis. In none of the studies did tartrazine challenge or avoidance in diet significantly alter asthma outcomes. Due to the paucity of available evidence, it is not possible to provide firm conclusions as to the effects of tartrazine on asthma control. However, the six RCTs that could be included in this review all arrived at the same conclusion. Routine tartrazine exclusion may not benefit most patients

  7. Asthma and Obstructive Sleep Apnea

    2015-01-01

    Full Text Available Objective: To get a comprehensive understanding about the relationship between obstructive sleep apnea (OSA and asthma by reviewing the epidemiology, pathophysiology, and clinical manifestation and then summarizing the latest progress on diagnosis and treatment. Data Sources: Articles referred in this review were mainly collected from a comprehensive search of the PubMed published in English from 1990 to 2015 with the terms "OSA" and "asthma" as the main keywords. Highly regarded older publications were also included. Study Selection: Information about the features of the two diseases in common, the pathophysiologic association between them and their current treatments from the literature search were identified, retrieved, and summarized. Results: Both OSA and asthma are very prevalent conditions. The incidences of them have kept on rising in recent years. Asthma is often accompanied by snoring and apnea, and OSA often combines with asthma, as well. They have many predisposing and aggravating factors in common. Possible shared direct mechanistic links between them include mechanical effects, intermittent hypoxia, nerve reflex, inflammation, leptin, etc. Indirect mechanistic links include medication, nose diseases, smoking, obesity, and gastroesophageal reflux disease. Since OSA presents many similar features with nocturnal asthma, some scholars termed them as a sole syndrome - "alternative overlap syndrome," and proved that asthma symptoms in those patients could be improved through the treatment of continuous positive airway pressure. Conclusions: OSA and asthma are closely associated in pathogenesis, symptoms, and therapies. With the growing awareness of the relationship between them, we should raise our vigilance on the coexistence of OSA in those difficult-to-control asthmatic patients. Further studies are still needed to guide the clinical works.

    Adolescence is a period of change, which coincides with disease remission in a significant proportion of subjects with childhood asthma. There is incomplete understanding of the changing characteristics underlying different adolescent asthma transitions. We undertook pathophysiological characterization of transitional adolescent asthma phenotypes in a longitudinal birth cohort. The Isle of Wight Birth Cohort (N = 1456) was reviewed at 1, 2, 4, 10 and 18-years. Characterization included questionnaires, skin tests, spirometry, exhaled nitric oxide, bronchial challenge and (in a subset of 100 at 18-years) induced sputum. Asthma groups were "never asthma" (no asthma since birth), "persistent asthma" (asthma at age 10 and 18), "remission asthma" (asthma at age 10 but not at 18) and "adolescent-onset asthma" (asthma at age 18 but not at age 10). Participants whose asthma remitted during adolescence had lower bronchial reactivity (odds ratio (OR) 0.30; CI 0.10 -0.90; p = 0.03) at age 10 plus greater improvement in lung function (forced expiratory flow 25-75% gain: 1.7 L; 1.0-2.9; p = 0.04) compared to persistent asthma by age 18. Male sex (0.3; 0.1-0.7; p adolescent-onset asthma showed eosinophilic airway inflammation (3.0%, 0.7-6.6), not seen in persistent asthma (1.0%, 0-3.9), while remission group had the lowest sputum eosinophil count (0.3%, 0-1.4) and lowest eosinophils/neutrophils ratio of 0.0 (Interquartile range: 0.1). Asthma remission during adolescence is associated with lower initial BHR and greater gain in small airways function, while adolescent-onset asthma is primarily eosinophilic.

    2017-04-01

    Full Text Available Background: The need for a national guideline, with a broad basis among specialists and primary care physicians was felt in Mexico, to try unifying asthma management. As several high-quality asthma guidelines exist worldwide, it was decided to select the best three for transculturation. Methods: Following the internationally recommended methodology for guideline transculturation, ADAPTE, a literature search for asthma guidelines, published 1-1-2007 through 31-12-2015 was conducted. AGREE-II evaluations yielded 3/40 most suitable for transculturation. Their compound evidence was fused with local reality, patient preference, cost and safety considerations to draft the guideline document. Subsequently, this was adjusted by physicians from 12 national medical societies in several rounds of a Delphi process and 3 face-to-face meetings to reach the final version. Results: Evidence was fused from British Thoracic Society Asthma Guideline 2014, Global Initiative on Asthma 2015, and Guía Española del Manejo del Asma 2015 (2016 updates included. After 3 Delphi-rounds we developed an evidence-based document taking into account patient characteristics, including age, treatment costs and safety and best locally available medication. Conclusion: In cooperation pulmonologists, allergists, ENT physicians, paediatricians and GPs were able to develop an evidence-based document for the prevention, diagnosis and treatment of asthma and its exacerbations in Mexico.

  11. Indoor Air Quality and Asthma

    Directory of Open Access Journals (Sweden)

    Robert Golden

    2017-02-01

    Full Text Available Numerous contaminants in indoor air and their potential to cause or exacerbate asthma continue to be a subject of public health concern. Many agents are causally associated with or can exacerbate asthma, particularly in children. For formaldehyde, an established respiratory irritant based on numerous studies, the evidence for an association with asthma is still considered only limited or suggestive. However, there is no evidence that indicates increased sensitivity to sensory irritation to formaldehyde in people often regarded as susceptible such as asthmatics. Acrolein, but not formaldehyde, was significantly associated with asthma in a large cohort of children. This prompted an evaluation of this highly irritating chemical that had never previously been considered in the context of the indoor air/childhood asthma issue. Because acrolein is more potent than formaldehyde as a respiratory irritant and ubiquitous in indoor air, it is plausible that previous studies on potential risk factors and childhood asthma may be confounded by formaldehyde acting as an unrecognized proxy for acrolein.

    Objective: To investigate warning symptoms of asthma attack and evaluate asthma self-management status of asthma patients in urban China. Methods: A multi-center, cross-sectional, questionnaire-based survey was carried out from 30 general hospitals dispersed in 30 provinces of mainland China (except for Tibet) during Oct 2015 to May 2016. Information of frequency and warning symptoms of asthma attack, the time from warning symptoms to asthma attack, the impact of asthma attack and asthma self-management were collected from asthma patients of outpatient department. Results: Altogether 3 875 asthmatic outpatients were recruited. 78.1% (3 026/3 875) of the patients reported restriction of exercise and daily activities during asthma exacerbation. 82.5% (3 160/3 829) of the patients had warning symptoms before asthma attack, the most common warning symptoms were cough, chest tightness and shortness of breath. The median time from warning symptoms to asthma attack was 2 h, the mean time was 90 h. Only 4.4% (167/3 829) of the patients had definite confidence to control asthma when symptoms deteriorated. 76.7% (2 937/3 828) of the patients used medications to control asthma when asthma symptoms deteriorated. Medication choice: inhaled corticosteroid (ICS) + formoterol 45.8% (1 776/3 875), short-acting beta-agonist (SABA) 23.9% (927/3 875). Conclusions: Most asthma patients have warning symptoms before asthma attack, the most common symptoms are cough, chest tightness and shortness of breath. The proportion of patients conducting effective asthma self-management remains low.

    The present paper addresses severe asthma which is limited to 5-10% of the overall population of asthmatics. However, it accounts for 50% or more of socials costs of the disease, as it is responsible for hospitalizations and Emergency Department accesses as well as expensive treatments. The recent identification of different endotypes of asthma, based on the inflammatory pattern, has led to the development of tailored treatments that target different inflammatory mediators. These are major achievements in the perspective of Precision Medicine: a leading approach to the modern treatment strategy. Omalizumab, an anti-IgE antibody, has been the only biologic treatment available on the market for severe asthma during the last decade. It prevents the linkage of the IgE and the receptors, thereby inhibiting mast cell degranulation. In clinical practice omalizumab significantly reduced the asthma exacerbations as well as the concomitant use of oral glucocorticoids. In the "Th2-high asthma" phenotype, the hallmarks are increased levels of eosinophils and other markers (such as periostin). Because anti-IL-5 in this condition plays a crucial role in driving eosinophil inflammation, this cytokine or its receptors on the eosinophil surface has been studied as a potential target for therapy. Two different anti-IL-5 humanized monoclonal antibodies, mepolizumab and reslizumab, have been proven effective in this phenotype of asthma (recently they both came on the market in the United States), as well as an anti-IL-5 receptor alpha (IL5Rα), benralizumab. Other monoclonal antibodies, targeting different cytokines (IL-13, IL-4, IL-17 and TSLP) are still under evaluation, though the preliminary results are encouraging. Finally, AIT, Allergen Immunotherapy, a prototype of Precision Medicine, is considered, also in light of the recent evidences of Sublingual Immunotherapy (SLIT) tablet efficacy and safety in mite allergic asthma patients. Given the high costs of these therapies

    2017-07-01

    Asthma is a common chronic disease in children. Uncontrolled asthma is a significant contributor to school absenteeism, emergency room visits, and hospitalization, all of which can lead to low school performance, financial burdens, and emotional problems for children and their parents. Asthma in children restricts the activities of school-aged children, such as participating in before- and after-school activity and extracurricular activities such as sports. Uncontrolled asthma has the potential to impact a student's self-confidence and social interactions. This article reviews the physical, emotional, and social burden of asthma on school-aged children/parents as well as recounting school asthma intervention programs. One of the roles of the school nurse is to be the leader of the intervention programs, manage asthma, and provide education for the students, parents, and school community to promote knowledge about asthma and its management.

  16. Mechanical ventilation for severe asthma.

    Science.gov (United States)

    Leatherman, James

    2015-06-01

    Acute exacerbations of asthma can lead to respiratory failure requiring ventilatory assistance. Noninvasive ventilation may prevent the need for endotracheal intubation in selected patients. For patients who are intubated and undergo mechanical ventilation, a strategy that prioritizes avoidance of ventilator-related complications over correction of hypercapnia was first proposed 30 years ago and has become the preferred approach. Excessive pulmonary hyperinflation is a major cause of hypotension and barotrauma. An appreciation of the key determinants of hyperinflation is essential to rational ventilator management. Standard therapy for patients with asthma undergoing mechanical ventilation consists of inhaled bronchodilators, corticosteroids, and drugs used to facilitate controlled hypoventilation. Nonconventional interventions such as heliox, general anesthesia, bronchoscopy, and extracorporeal life support have also been advocated for patients with fulminant asthma but are rarely necessary. Immediate mortality for patients who are mechanically ventilated for acute severe asthma is very low and is often associated with out-of-hospital cardiorespiratory arrest before intubation. However, patients who have been intubated for severe asthma are at increased risk for death from subsequent exacerbations and must be managed accordingly in the outpatient setting.

    2016-08-01

    In 2015, progress in understanding asthma ranged from insights to asthma inception, exacerbations, and severity to advancements that will improve disease management throughout the lifespan. 2015's insights to asthma inception included how the intestinal microbiome affects asthma expression with the identification of specific gastrointestinal bacterial taxa in early infancy associated with less asthma risk, possibly by promoting regulatory immune development at a critical early age. The relevance of epigenetic mechanisms in regulating asthma-related gene expression was strengthened. Predicting and preventing exacerbations throughout life might help to reduce progressive lung function decrease and disease severity in adulthood. Although allergy has long been linked to asthma exacerbations, a mechanism through which IgE impairs rhinovirus immunity and underlies asthma exacerbations was demonstrated and improved by anti-IgE therapy (omalizumab). Other key molecular pathways underlying asthma exacerbations, such as cadherin-related family member 3 (CDHR3) and orosomucoid like 3 (ORMDL3), were elucidated. New anti-IL-5 therapeutics, mepolizumab and reslizumab, were US Food and Drug Administration approved for the treatment of patients with severe eosinophilic asthma. In a clinical trial the novel therapeutic inhaled GATA3 mRNA-specific DNAzyme attenuated early- and late-phase allergic responses to inhaled allergen. These current findings are significant steps toward addressing unmet needs in asthma prevention, severity modification, disparities, and lifespan outcomes.

    The current study focused on the role of trait mindfulness in asthma-related quality of life (QoL) and asthma control in adolescent asthma patients. Furthermore, potential underlying mechanisms (general and asthma-specific stress) of this relationship were investigated. In this cross-sectional study, questionnaire data of 94 adolescents with asthma that were prescribed daily asthma medication were included. Two Structural Equation Models (SEMs), a direct model and an indirect model, were tested. We found that trait mindfulness was directly related to asthma-related QoL, but not to asthma control. The relationship between trait mindfulness and asthma-related QoL was explained by asthma-specific, but not by general stress. Furthermore, an indirect relation from mindfulness to asthma control via asthma-specific stress was found. Cross-sectional evidence for a relation between mindfulness and asthma-related QoL is found. These findings may point to the possibility that an intervention aimed at increasing mindfulness could be a promising tool to improve asthma-related QoL in adolescents via a decrease in asthma-specific stress.

    People with asthma spend a significant amount of time in the workplace but little is known about the current state of disease management in such contexts. The aim of the current study is to explore the experiences, attitudes and perceptions of asthma across different stakeholders in the workplace to help inform potential recommendations for workplace asthma policies. Using purposive and convenience sampling methods, in-depth semi-structured interviews were conducted in Australia with 5 human resource personnel, 10 employees with asthma and 10 employees without asthma. Interviews were guided by a schedule of questions focusing on attitudes and experiences of people with asthma in the workplace, which were audio recorded, transcribed verbatim and thematically analysed. Analysis of the qualitative dataset revealed three key themes: Beliefs and Attitudes about Asthma, Asthma Solutions in the Workplace and Workplace Obstacles. Findings suggest that employees with asthma experience problems managing their asthma at work and there is a lack of workplace support in relation to asthma emergency management. Key recommendations for workplace asthma policies have been made to provide better support for employees with asthma. However, further investigation into the experience of managing asthma is required in a wider variety of occupations and work experiences to inform the development of a workplace asthma policy.

    Obstructive lung diseases represent a major health problem worldwide due to their high prevalence associated with elevated socioeconomic costs. Bronchial asthma and chronic obstructive pulmonary disease are chronic obstructive ventilatory disorders with airway inflammation, however they are separate nosological entities based on thedifferent development, diagnostic and therapeutic approaches, and prognostic features. However, these diseases may coexist and can be defined as the coexistence of increased variability of airflow in a patient with incompletely reversible airway obstruction. This phenotype is called asthma - chronic obstructive pulmonary disease overlap syndrome. The syndrome is a clinical and scientific challenge as the majority of these patients have been excluded from the clinical and pharmacological trials, thus well-defined clinical characteristics and therapeutic approaches are lacking. The aim of this review is to summarize the currently available literature focusing on pathophysiological and clinical features, and discuss possible therapeutic approaches of patients with asthma - chronic obstructive pulmonary disease overlap syndrome.

  9. The interplay between neuroendocrine activity and psychological stress-induced exacerbation of allergic asthma

    Directory of Open Access Journals (Sweden)

    Tomomitsu Miyasaka

    2018-01-01

    Full Text Available Psychological stress is recognized as a key factor in the exacerbation of allergic asthma, whereby brain responses to stress act as immunomodulators for asthma. In particular, stress-induced enhanced type 2 T-helper (Th2-type lung inflammation is strongly associated with asthma pathogenesis. Psychological stress leads to eosinophilic airway inflammation through activation of the hypothalamic-pituitary-adrenal pathway and autonomic nervous system. This is followed by the secretion of stress hormones into the blood, including glucocorticoids, epinephrine, and norepinephrine, which enhance Th2 and type 17 T-helper (Th17-type asthma profiles in humans and rodents. Recent evidence has shown that a defect of the μ-opioid receptor in the brain along with a defect of the peripheral glucocorticoid receptor signaling completely disrupted stress-induced airway inflammation in mice. This suggests that the stress response facilitates events in the central nervous and endocrine systems, thus exacerbating asthma. In this review, we outline the recent findings on the interplay between stress and neuroendocrine activities followed by stress-induced enhanced Th2 and Th17 immune responses and attenuated regulatory T (Treg cell responses that are closely linked with asthma exacerbation. We will place a special focus on our own data that has emphasized the continuity from central sensing of psychological stress to enhanced eosinophilic airway inflammation. The mechanism that modulates psychological stress-induced exacerbation of allergic asthma through neuroendocrine activities is thought to involve a series of consecutive pathological events from the brain to the lung, which implies there to be a “neuropsychiatry phenotype” in asthma.

    Background “Asthma-related quality of life” refers to the perceived impact that asthma has on the patient’s quality of life. Objective National Institutes of Health (NIH) institutes and other federal agencies convened an expert group to recommend standardized measures of the impact of asthma on quality of life for use in future asthma clinical research. Methods We reviewed published documentation regarding the development and psychometric evaluation; clinical research use since 2000; and extent to which the content of each existing quality of life instrument provides a unique, reliable, and valid assessment of the intended construct. We classified instruments as core (required in future studies), supplemental (used according to the study’s aims and standardized), or emerging (requiring validation and standardization). This work was discussed at an NIH-organized workshop convened in March 2010 and finalized in September 2011. Results Eleven instruments for adults and 6 for children were identified for review. None qualified as core instruments because they predominantly measured indicators of asthma control (symptoms and/or functional status); failed to provide a distinct, reliable score measuring all key dimensions of the intended construct; and/or lacked adequate psychometric data. Conclusions In the absence of existing instruments that meet the stated criteria, currently available instruments are classified as either supplemental or emerging. Research is strongly recommended to develop and evaluate instruments that provide a distinct, reliable measure of the patient’s perception of the impact of asthma on all of the key dimensions of quality of life, an important outcome that is not captured in other outcome measures.

  11. Prenatal stress, prematurity and asthma

    Medsker, Brock; Forno, Erick; Simhan, Hyagriv; Celedón, Juan C.

    2016-01-01

    Asthma is the most common chronic disease of childhood, affecting millions of children in the U.S. and worldwide. Prematurity is a risk factor for asthma, and certain ethnic or racial minorities such as Puerto Ricans and non-Hispanic Blacks are disproportionately affected by both prematurity and asthma. In this review, we examine current evidence to support maternal psychosocial stress as a putative link between prematurity and asthma, while also focusing on disruption of the hypothalamic-pituitary-adrenal (HPA) axis and immune responses as potential underlying mechanisms for stress-induced “premature asthma”. Prenatal stress may not only cause abnormalities in the HPA axis but also epigenetic changes in the fetal glucocorticoid receptor gene (NR3C1), leading to impaired glucocorticoid metabolism. Moreover, maternal stress can alter fetal cytokine balance, favoring Th2 (allergic) immune responses characteristic of atopic asthma: IL-6, which has been associated with premature labor, can promote Th2 responses by stimulating production of IL-4 and IL-13. Given a link among stress, prematurity, and asthma, future research should include birth cohorts aimed at confirming and better characterizing “premature asthma”. If confirmed, clinical trials of prenatal maternal stress reduction would be warranted to reduce the burden of these common co-morbidities. While awaiting the results of such studies, sound policies to prevent domestic and community violence (e.g. from firearms) are justified, not only by public safety but also by growing evidence of detrimental effects of violence-induced stress on psychiatric and somatic health.

  12. Communicating with children with asthma.

    Science.gov (United States)

    Callery, Peter

    Nurses are expected to treat children, young people and their parents as individuals and respect their dignity. Some information about asthma symptoms and about what is most important to children can only be obtained by communicating directly with children themselves rather than relying on parents. Consultations about children's asthma usually have three participants--nurse, parent and child. Children often take a passive role or are marginalised, sometimes by parents' interventions. Nurses need to take account of children's views and preferences, and build alliances with parents and children. Nursing needs to develop its own evidence base for practice, to underpin training and education.

  13. Towards easy and reliable AFM tip shape determination using blind tip reconstruction

    International Nuclear Information System (INIS)

    Flater, Erin E.; Zacharakis-Jutz, George E.; Dumba, Braulio G.; White, Isaac A.; Clifford, Charles A.

    2014-01-01

    Quantitative determination of the geometry of an atomic force microscope (AFM) probe tip is critical for robust measurements of the nanoscale properties of surfaces, including accurate measurement of sample features and quantification of tribological characteristics. Blind tip reconstruction, which determines tip shape from an AFM image scan without knowledge of tip or sample shape, was established most notably by Villarrubia [J. Res. Natl. Inst. Stand. Tech. 102 (1997)] and has been further developed since that time. Nevertheless, the implementation of blind tip reconstruction for the general user to produce reliable and consistent estimates of tip shape has been hindered due to ambiguity about how to choose the key input parameters, such as tip matrix size and threshold value, which strongly impact the results of the tip reconstruction. These key parameters are investigated here via Villarrubia's blind tip reconstruction algorithms in which we have added the capability for users to systematically vary the key tip reconstruction parameters, evaluate the set of possible tip reconstructions, and determine the optimal tip reconstruction for a given sample. We demonstrate the capabilities of these algorithms through analysis of a set of simulated AFM images and provide practical guidelines for users of the blind tip reconstruction method. We present a reliable method to choose the threshold parameter corresponding to an optimal reconstructed tip shape for a given image. Specifically, we show that the trend in how the reconstructed tip shape varies with threshold number is so regular that the optimal, or Goldilocks, threshold value corresponds with the peak in the derivative of the RMS difference with respect to the zero threshold curve vs. threshold number. - Highlights: • Blind tip reconstruction algorithms have been implemented and augmented to determine the optimal input parameters. • We demonstrate the capabilities of the algorithms using a simulated AFM

    This paper focuses on the influences of the tip mass ratio (the ratio of the tip mass to the cantilever mass), on the excitation of higher oscillation eigenmodes and also on the tip-sample interaction forces in tapping mode atomic force microscopy (TM-AFM). A precise model for the cantilever dynamics capable of accurate simulations is essential for the investigation of the tip mass effects on the interaction forces. In the present work, the finite element method (FEM) is used for modeling the AFM cantilever to consider the oscillations of higher eigenmodes oscillations. In addition, molecular dynamics (MD) is used to calculate precise data for the tip-sample force as a function of tip vertical position with respect to the sample. The results demonstrate that in the presence of nonlinear tip-sample interaction forces, the tip mass ratio plays a significant role in the excitations of higher eigenmodes and also in the normal force applied on the surface. Furthermore, it has been shown that the difference between responses of the FEM and point-mass models in different system operational conditions is highly affected by the tip mass ratio. -- Highlights: {yields} A strong correlation exists between the tip mass ratio and the 18th harmonic amplitude. {yields} Near the critical tip mass ratio a small change in the tip mass may lead to a significant force change. {yields} Inaccuracy of the lumped model depends significantly on the tip mass ratio.

    The Kaplan turbine has a small clearance gap between the blade tip and casing to allow the blades to rotate freely. This clearance gap is the cause of an undesirable Tip Leakage Vortex (TLV). A TLV might reduce the turbine efficiency, erode the turbine blades or cause instabilities for the power output. A literature study indicated that the tip clearance gap was a critical parameter affecting the behavior of the TLV. A research gap was observed for an operating Kaplan turbine where the ...

    The present study is related to the development of the tip vortex cavitation in Kaplan turbines. The investigation is carried out on a simplified test case consisting of a NACA0009 blade with a gap between the blade tip and the side wall. Computations with and without cavitation are performed using a R ANS modelling and a transport equation for the liquid volume fraction. Compared with experimental data, the R ANS computations turn out to be able to capture accurately the development of the tip vortex. The simulations have also highlighted the influence of cavitation on the tip vortex trajectory.

    To describe the information needs of a group of Australians with asthma and the extent to which their needs had been met. A self-administered survey was completed by people with asthma either presenting at community pharmacies or registered with a medical research institute database. The survey questions were developed based on a review of the literature, and included questions regarding participants' information needs about their asthma, their sources of asthma information and the extent to which these information needs had been met. The responses concerning information needs were analysed thematically. Responses concerning sources of asthma information and the extent to which needs were met were analysed using descriptive and correlational statistics. Seventy-one people completed the survey. Key information needs that were identified included medications, management of asthma, asthma triggers, cure, aetiology of asthma and latest research. A third of participants reported having only 'very little', 'a little' or 'some' of their information needs met. The most common source of information was from a doctor (94% respondents), followed by a pharmacist or pharmacy assistant (56%). Insights into the information needs of people with asthma have been provided. In light of the level of unmet information needs of people with asthma, and the types of information sought, pharmacists are in an ideal position to close the information gap and promote optimal asthma self-management practices. © 2013 Royal Pharmaceutical Society.

    To examine the concordance between spirometry and asthma symptoms in assessing asthma severity and beginning therapy by the general pediatrician. Between 2008 and 2012, spirometry testing was satisfactorily performed in 894 children (ages 5-19 years) whose asthma severity had been determined by their pediatrician using asthma guideline-based clinical criteria. Spirometry-determined asthma severity using national asthma guidelines and clinician-determined asthma severity were compared for concordance using weighted Kappa coefficients. Thirty percent of participants had clinically determined intermittent asthma; 32%, 33%, and 5% had mild, moderate, and severe, persistent asthma, respectively. Increasing disease severity was associated with decreases in the forced expiratory volume in 1 second/forced vital capacity (FVC) ratio (P spirometry-determined severity. Concordance was 0.16 (95% CI 0.10, 0.23), and when adjusted for bias and prevalence, was 0.20 (95% CI 0.17, 0.23). When accounting for age, sex, exposure to smoke, and insurance type, only spirometry-determined asthma severity was a significant predictor of agreement (P spirometry-determined severity increased. Concordance between spirometry and asthma symptoms in determining asthma severity is low even when guideline-based clinical assessment tools are used. Because appropriate therapy reduces asthma morbidity and is guided by disease severity, results from spirometry testing could better guide pediatricians in determining appropriate therapy for their patients with asthma.

    Obesity is associated with an increased risk of asthma in children. Atopic sensitization is a major risk factor for asthma including severe asthma in children. It is unclear if obesity is associated with worse asthma control or severity in children and how its effects compare to atopy. We sought to examine relationships of weight status and atopy to asthma control and severity among a population of predominantly low income, minority children and adolescents with persistent asthma. A cross-sectional analysis of 832 children and adolescents, age range 5-17 years, with persistent asthma was performed. Clinical assessments included asthma questionnaires of symptoms, asthma severity score, health care utilization and medication treatment step, lung function testing, and skin prick testing as well as measures of adiposity. Data were collected between December 2010 and August 2014 from Johns Hopkins Hospital in Baltimore, MD and Children's Hospital of Boston, MA. Obesity was not associated with worse asthma control or severity in this group of predominantly low income, minority children and adolescents with persistent asthma. However, a greater degree of atopy was associated with lower lung function, higher asthma severity score, and higher medication treatment step. Atopy may be a more important risk factor for asthma severity than obesity among low-income minority children and adolescents with persistent asthma living in Northeastern cities in the United States.

    SUMMARY Dietary changes may partly explain the high burden of asthma in industrialized nations. Experimental studies have motivated a significant number of observational studies of the relation between vitamins (A, C, D, and E) or nutrients acting as methyl donors (folate, vitamin B12, and choline) and asthma. Because observational studies are susceptible to several sources of bias, well-conducted randomized controlled trials (RCTs) remain the “gold standard” to determine whether a vitamin or nutrient has an effect on asthma. Evidence from observational studies and/or relatively few RCTs most strongly justify ongoing and future RCTs of: 1) vitamin D to prevent or treat asthma, 2) choline supplementation as adjuvant treatment for asthma, and 3) vitamin E to prevent the detrimental effects of air pollution in subjects with asthma. At this time, there is insufficient evidence to recommend supplementation with any vitamin or nutrient acting as a methyl donor to prevent or treat asthma. PMID:24461761

    Workplace bullying (WPB) behaviors negatively affect nurse productivity, satisfaction, and retention, and hinder safe patient care. The purpose of this article is to define WPB, differentiate between incivility and WPB, and recommend actions to prevent WPB behaviors. Informed occupational and environmental health nurses and nurse leaders must recognize, confront, and eliminate WPB in their facilities and organizations. Recognizing, confronting, and eliminating WPB behaviors in health care is a crucial first step toward sustained improvements in patient care quality and the health and safety of health care employees. © 2016 The Author(s).

    Many African Americans (AAs) use clergy as their primary source of help for depression, with few being referred to mental health providers. This study used face-to-face workshops to train AA clergy to recognize the symptoms and levels of severity of depression. A pretest/posttest format was used to test knowledge (N = 42) about depression symptoms. Results showed that the participation improved the clergy's ability to recognize depression symptoms. Faith community nurses can develop workshops for clergy to improve recognition and treatment of depression.

This task encapsulates Natural Language Understanding capabilities within a very simple interface: recognizing when the meaning of a text snippet is contained in the meaning of a second piece of text. This simple abstraction of an exceedingly complex problem has broad appeal partly because it can be conceived also as a component in other NLP applications, from Machine Translation to Semantic Search to Information Extraction.

    Pike, Katharine C; Levy, Mark L; Moreiras, John; Fleming, Louise

    2018-04-01

    This review discusses issues related to managing problematic severe asthma in children and young people. A small minority of children have genuinely severe asthma symptoms which are difficult to control. Children with genuinely severe asthma need investigations and treatments beyond those described within conventional guidelines. However, the majority of children with poor symptom control despite high-intensity treatment achieve improvement in their asthma control once attention has been paid to the basics of asthma management. Basic asthma management requires optimisation of inhaler technique and treatment adherence, avoidance of environmental triggers and self-management education. It is also important that clinicians recognise risk factors that predispose patients to asthma exacerbations and potentially life-threatening attacks. These correctable issues need to be tackled in partnership with children and young people and their families. This requires a coordinated approach between professionals across healthcare settings. Establishing appropriate infrastructure for coordinated asthma care benefits not only those with problematic severe asthma, but also the wider asthma population as similar correctable issues exist for children with asthma of all severities. Investigation and management of genuine severe asthma requires specialist multidisciplinary expertise and a systematic approach to characterising patients' asthma phenotypes and delivering individualised care. While inhaled corticosteroids continue to play a leading role in asthma therapy, new treatments on the horizon might further support phenotype-specific therapy. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    baker's asthma is a well-known occupational lung disease which usually develops in adults. We report the case of a two years old boy who suffered from asthma, urticaria and atopic dermatitis for twelve months, whose symptoms were associated to visits to his grandfather's bakery. skin prick tests (SPT) were made to dust mites, moulds, flours, alfa-amylase and egg. It was also determined total IgE and specific IgE antibodies to alfa-amylase and flours. Subsequently, a challenge test was carried out with wheat flour. The SPTs were positive to flours, alfa-amylase and egg. The determination of specific IgE antibodies showed 2.64 kU/L to wheat, 0.79 kU/L to glyadin and 2.98 kU/L to alfa-amylase. The patient developed asthma and rhinitis after manipulating wheat flour for 10 min. we demonstrated a type I hypersensitivity to wheat flour and alfa-amylase in a two years old child by SPT, specific IgE antibodies and challenge test. This case in the childhood equivalent of occupational baker's asthma.

    Nitric oxide (NO) and carbon monoxide (CO) are synthesized at high levels in asthmatic airways. NO can oxidize hemoglobin (Hb) to methemoglobin (MetHb). CO binds to heme to produce carboxyhemoglobin (COHb). We hypothesized that MetHb and COHb may be increased in asthma. COHb, MetHb, and Hb were measured in venous blood of healthy controls (n = 32) and asthmatics (n = 31). Arterial COHb and oxyhemoglobin were measured by pulse CO-oximeter. Hb, oxyhemoglobin, and deoxyhemoglobin were similar among groups, but arterial COHb was higher in asthmatics than controls (p = 0.04). Venous COHb was similar among groups, and thus, arteriovenous COHb (a-v COHb) concentration difference was greater in asthma compared with controls. Venous MetHb was lower in asthma compared to controls (p = 0.01) and correlated to venous NO (p = 0.009). The greater a-v COHb in asthma suggests CO offloading to tissues, but lower than normal MetHb suggests countermeasures to avoid adverse effects of high NO on gas transfer.

    Full Text Available To characterize the clinical features of fatal asthma, we retrospectively analyzed the clinical characteristics of patients who died of an acute asthma attack in our hospital during a 15-year period from 1989 to 2003. Twelve patients had fatal asthma during this period, including eight who were dead on arrival in the emergency room (ER and three who died within 1 hour of admission to the ER. Patients were categorized into three groups according to the clinical presentations during the fatal attack: (1 rapid (< 3 hours decompensation in four patients; (2 gradual development of respiratory failure over several days in two patients; and (3 acute deterioration after unstable asthma lasting several days in six patients. All patients in groups 1 and 2 had reported previous near-fatal attacks. The proportion of young patients was highest in group 3, with half of them (3/6 younger than 35 years of age. Only one patient in group 3 had had a previous near-fatal attack. Five of the seven patients, with previous near-fatal attacks, had a pattern of decompensation during their fatal attack that was similar to their previous attacks. In conclusion, nearly all patients with fatal asthma in this study died outside of the hospital or within 1 hour after admission to the ER. Patients had patterns of decompensation during the fatal attack that were similar to those of their previous attacks. Early detection of warning signs, early admission to the ER, adequate treatment, and extremely close observation of patients, especially within 1 hour after ER arrival, may prevent or decrease the incidence of fatal asthmatic attack.

    Few studies have examined school nurses preferences' for asthma training. Our purpose was to: 1) assess school nurses' perceived asthma training needs, 2) describe nurses' access to asthma educational resources, and 3) identify urban-rural differences in training needs and access to resources in southern states. A convenience sample of school nurses (n=162) from seven counties (two urban and five rural) in North Carolina and South Carolina completed an online, anonymous survey. Chi-square tests were used to examine urban-rural differences. Although most nurses (64%) had received asthma training within the last five years, urban nurses were more likely to have had asthma training than rural nurses (χ 2 =10.84, p=0.001). A majority of nurses (87%) indicated they would like to receive additional asthma training. Approximately half (45%) of nurses reported access to age-appropriate asthma education materials, but only 16% reported that their schools implemented asthma education programs. Urban nurses were more likely than rural nurses to have access to asthma education programs (χ 2 =4.10, p=0.04) and age-appropriate asthma education materials (χ 2 =8.86, p=0.003). Few schools are implementing asthma education programs. Rural nurses may be disadvantaged in terms of receiving asthma training and having access to asthma education programs and materials. Schools are an ideal setting for delivering age-appropriate asthma education. By providing school nurses with access to age-appropriate asthma education resources and additional asthma training, we can help them overcome several of the barriers that impede their ability to deliver asthma care to their students.

The aim of the present paper is to systematically review the current knowledge of the effect on overall asthma control of weight reduction in overweight and obese adults with asthma.Results: Weight loss in obese individuals with doctor-diagnosed asthma is associated with a 48%–100% remission of asthma symptoms and use of asthma medication. Published studies, furthermore, reveal that weight loss in obese asthmatics improves asthma control, and that especially surgically induced weight loss results in significant improvements in asthma severity, use of asthma medication, dyspnoea, exercise tolerance, and acute exacerbations, including hospitalizations due to asthma. Furthermore, weight loss in obese asthmatics is associated with improvements in level of lung function and airway responsiveness to inhaled methacholine, whereas no significant improvements have been observed in exhaled nitric oxide or other markers of eosinophilic airway inflammation.Conclusion: Overweight and obese adults with asthma experience a high symptomatic remission rate and significant improvements in asthma control, including objective measures of disease activity, after weight loss. Although these positive effects of weight loss on asthma-related health outcomes seem not to be accompanied by remission or improvements in markers of eosinophilic airway inflammation, it has potentially important implications for the future burden of asthma.Keywords: asthma, weight loss, diet, bariatric surgery, asthma control

    Uncontrolled asthma decreases quality of life and increases health care use. Most people with asthma need daily use of long-term control (LTC) medications for asthma symptoms and to prevent asthma attacks. Ongoing assessment of a person's level of asthma control and medication use is important in determining the effectiveness of current treatment to decrease the frequency and intensity of symptoms and functional limitations. To assess the use of LTC medication among children and adults with current asthma and identify contributing factors for LTC medication use. We used the 2006-2010 Behavioral Risk Factor Surveillance System (BRFSS) child and adult Asthma Call-back Survey (ACBS) data to assess the level of asthma control and LTC medication use. Asthma control was classified as well controlled and uncontrolled using guideline-based measures. We used multivariable logistic regression models to identify contributing factors for LTC medication use and having uncontrolled asthma. Among persons with current asthma, 46.0% of children and 41.5% of adults were taking LTC medications and 38.4% of children and 50.0% of adults had uncontrolled asthma. Among children who had uncontrolled asthma (38.4%), 24.1% were taking LTC medications and 14.3% were not taking LTC medications. Among adults who had uncontrolled asthma (50.0%), 26.7% were taking LTC medications and 23.3% were not taking LTC medications. Using BRFSS ACBS data to assess the level of asthma control and LTC medication use can identify subpopulations of persons with asthma who receive suboptimal treatment, for which better asthma-related medical treatment and management are needed.

    To investigate the perceptions and attitudes towards asthma management of general practitioners, pharmacists and people with asthma in a rural area. Qualitative semistructured interviews. Small rural centre in New South Wales. General practitioners, pharmacists and people with asthma in a rural area. General practitioners perceived that the patient provided a barrier to the implementation of optimal asthma services. They were aware that other health care professionals had a role in asthma management but were not aware of the details, particularly in relation to that of the pharmacist and would like to improve communication methods. Pharmacists also perceived the patient to be a barrier to the delivery of optimal asthma management services and would like to improve communication with the general practitioner. The impact of the rural environment for the health care professionals included workforce shortages, availability of support services and access to continuing education. People with asthma were satisfied with their asthma management and the service provided by the health care professionals and described the involvement of family members and ambulance officers in their overall asthma management. The rural environment was an issue with regards to distance to the hospital during an emergency. General practitioners and pharmacists confirmed their existing roles in asthma management while expressing a desire to improve communication between the two professions to help overcome barriers and optimise the asthma service delivered to the patient. The patient described minimal barriers to optimising asthma management, which might suggest that they might not have great expectations of asthma care.

    A climate 'tipping point' occurs when a small change in forcing triggers a strongly nonlinear response in the internal dynamics of part of the climate system, qualitatively changing its future state. Human-induced climate change could push several large-scale 'tipping elements' past a tipping point. Candidates include irreversible melt of the Greenland ice sheet, dieback of the Amazon rainforest and shift of the West African monsoon. Recent assessments give an increased probability of future tipping events, and the corresponding impacts are estimated to be large, making them significant risks. Recent work shows that early warning of an approaching climate tipping point is possible in principle, and could have considerable value in reducing the risk that they pose.

    Though severe or refractory asthma merely affects less than 10% of asthma population, it consumes significant health resources and contributes significant morbidity and mortality. Severe asthma does not fell in the routine definition of asthma and requires alternative treatment strategies. It has been observed that asthma severity increases with higher body mass index. The obese-asthmatics, in general, have the features of metabolic syndrome and are progressively causing a significant burden for both developed and developing countries thanks to the westernization of the world. As most of the features of metabolic syndrome seem to be originated from central obesity, the underlying mechanisms for metabolic syndrome could help us to understand the pathobiology of obese-asthma condition. While mitochondrial dysfunction is the common factor for most of the risk factors of metabolic syndrome, such as central obesity, dyslipidemia, hypertension, insulin resistance, and type 2 diabetes, the involvement of mitochondria in obese-asthma pathogenesis seems to be important as mitochondrial dysfunction has recently been shown to be involved in airway epithelial injury and asthma pathogenesis. This review discusses current understanding of the overlapping features between metabolic syndrome and asthma in relation to mitochondrial structural and functional alterations with an aim to uncover mechanisms for obese-asthma.

    Full Text Available Recent asthma deaths were examined from yearly reports of the Ministry of Health, Labor and Welfare of Japan and from reports published by the Japan Asthma Death Investigation Committee on 811 deaths over the period 1992–2000. The rate and number of recent asthma deaths in Japan have been decreasing rapidly. Most asthma deaths were of patients aged 70–90 years and there has been a marked trend for increased asthma deaths in the elderly. As for the circumstances surrounding the deaths, sudden death, unstable sudden aggravation and intermittent aggravation were mainly noted. Respiratory infections, fatigue and stress were the major courses of fatal attacks contributing to deaths due to asthma. Many of the patients who died from asthma had been diagnosed as having as moderate to severe asthma and many had non-atopic asthma. There are some reports that suggest that the recent decrease in asthma deaths in Japan is correlated with the use of inhaled cortico- steroids.

    Full Text Available Childhood asthma prevalence and morbidity have been shown to vary by neighborhood. Less is known about between-school variation in asthma prevalence and whether it exists beyond what one might expect due to students at higher risk of asthma clustering within different schools. Our objective was to determine whether between-school variation in asthma prevalence exists and if so, if it is related to the differential distribution of individual risk factors for and correlates of asthma or to contextual influences of schools.Cross-sectional analysis of 16,640 teens in grades 7-12 in Wave 1 (data collected in 1994-5 of the National Longitudinal Study of Adolescent Health. Outcome was current diagnosis of asthma as reported by respondents' parents. Two-level random effects models were used to assess the contribution of schools to the variance in asthma prevalence before and after controlling for individual attributes.The highest quartile schools had mean asthma prevalence of 21.9% compared to the lowest quartile schools with mean asthma prevalence of 7.1%. In our null model, the school contributed significantly to the variance in asthma (sigma(u0(2 = 0.27, CI: 0.20, 0.35. Controlling for individual, school and neighborhood attributes reduced the between-school variance modestly (sigma(u0(2 = 0.19 CI: 0.13-0.29.Significant between-school variation in current asthma prevalence exists even after controlling for the individual, school and neighborhood factors. This provides evidence for school level contextual influences on asthma. Further research is needed to determine potential mechanisms through which schools may influence asthma outcomes.

  14. 2003 Canadian Asthma Consensus Guidelines Executive Summary

    2006-03-01

    Full Text Available Abstract Background Guidelines for the diagnosis and management of asthma have been published over the last 15 years; however, there has been little focus on issues relating to asthma in childhood. Since the last revision of the 1999 Canadian Asthma Consensus Report, important new studies, particularly in children, have highlighted the need to incorporate new information into the asthma guidelines. The objectives of this article are to review the literature on asthma published between January 2000 and June 2003 and to evaluate the influence of new evidence on the recommendations made in the 1999 Canadian Asthma Consensus Report and its 2001 update, with a major focus on pediatric issues. Methods The diagnosis of asthma in young children and prevention strategies, pharmacotherapy, inhalation devices, immunotherapy, and asthma education were selected for review by small expert resource groups. The reviews were discussed in June 2003 at a meeting under the auspices of the Canadian Network For Asthma Care and the Canadian Thoracic Society. Data published through December 2004 were subsequently reviewed by the individual expert resource groups. Results This report evaluates early-life prevention strategies and focuses on treatment of asthma in children, emphasizing the importance of early diagnosis and preventive therapy, the benefits of additional therapy, and the essential role of asthma education. Conclusion We generally support previous recommendations and focus on new issues, particularly those relevant to children and their families. This document is a guide for asthma management based on the best available published data and the opinion of health care professionals, including asthma experts and educators.

    To determine the feasibility of transcaval transjugular intrahepatic portosystemic shunt (TIPS) in patients with occluded previous TIPS. Between February 1996 and December 2000 we performed five transcaval TIPS procedures in four patients with recurrent gastric cardiac variceal bleeding. All four had occluded TIPS, which was between the hepatic and portal vein. The interval between initial TIPS placement and revisional procedures with transcaval TIPS varied between three and 31 months; one patient underwent transcaval TIPS twice, with a 31-month interval. After revision of the occluded shunt failed, direct cavoportal puncture at the retrohepatic segment of the IVC was attempted. Transcaval TIPS placement was technically successful in all cases. In three, tractography revealed slight leakage of contrast materials into hepatic subcapsular or subdiaphragmatic pericaval space. There was no evidence of propagation of extravasated contrast materials through the retroperitoneal space or spillage into the peritoneal space. After the tract was dilated by a bare stent, no patient experienced trans-stent bleeding and no serious procedure-related complications occurred. After successful shunt creation, variceal bleeding ceased in all patients. Transcaval TIPS placement is an effective and safe alternative treatment in patients with occluded previous TIPS and no hepatic veins suitable for new TIPS.

  16. The tipping point: A mathematical model for the profit-driven abandonment of restaurant tipping

    2018-02-01

    The custom of voluntarily tipping for services rendered has gone in and out of fashion in America since its introduction in the 19th century. Restaurant owners that ban tipping in their establishments often claim that social justice drives their decisions, but we show that rational profit-maximization may also justify the decisions. Here, we propose a conceptual model of restaurant competition for staff and customers, and we show that there exists a critical conventional tip rate at which restaurant owners should eliminate tipping to maximize profits. Because the conventional tip rate has been increasing steadily for the last several decades, our model suggests that restaurant owners may abandon tipping en masse when that critical tip rate is reached.

    Full Text Available In 2011, the Florida Asthma Coalition began offering its Asthma-Friendly Childcare Center training online. This course teaches childcare center employees the fundamentals of effective asthma management. It covers basic asthma physiology, ways to recognize asthma attacks, techniques to help children experiencing attacks, and strategies to create healthy environments for asthmatics. A team of health services researchers evaluated both years of the online training. Evaluators used a quasi-experimental design with pretest, posttest, and follow-up assessment. Questions measured knowledge gain and retention, user satisfaction, and implementation of management strategies. Over 650 people from nearly all 67 Florida counties took AFCC training online between 2011 and 2013. Test scores improved by a minimum of 11 percentage points in all program years evaluated. Gains in both knowledge and confidence were substantial and highly significant across years. While individual trainees did forget some content on follow-up, they seemed to retain the specific messages most relevant for their own workplaces. Most trainees also planned to implement multiple management strategies recommended by the training.A large majority of participants rated the training as excellent on all quality metrics, including relevance of content and time efficiency of the online format. Nearly all respondents perceived the training as useful for both providing improved care and fulfilling licensure or certification requirements. Many participants also indicated that their centers would pursue formal certification as AFCCs via the program offered by FAC. The online AFCC course performed strongly in its first years, yielding both high participant satisfaction and substantial improvement in workplace asthma management activity. This training holds promise for introducing and improving multidimensional asthma management strategies at childcare facilities nationwide.

  19. Effect of asthma severity on symptom perception in childhood asthma

    2002-03-01

    Full Text Available Individual ability to perceive airway obstruction varies substantially. The factors influencing the perception of asthma are probably numerous and not well established in children. The present study was designed to examine the influence of asthma severity, use of preventive medication, age and gender on the association between respiratory symptoms (RS and peak expiratory flow (PEF rates in asthmatic children. We followed 92 asthmatic children, aged 6 to 16 years, for five months. Symptom scores were recorded daily and PEF was measured twice a day. The correlations among variables at the within-person level over time were analyzed for each child and for the pooled data by multivariate analysis. After pooling the data, there was a significant (P<0.05 correlation between each symptom and PEF; 60% of the children were accurate perceivers (defined by a statistically significant correlation between symptoms and PEF across time for diurnal symptoms and 37% for nocturnal symptoms. The accuracy of perception was independent of asthma severity, age, gender or the use of preventive medication. Symptom perception is inaccurate in a substantial number of asthmatic children, independently of clinical severity, age, gender or use of preventive medication. It is not clear why some asthmatic patients are capable of accurately perceiving the severity of airway obstruction while others are not.

    Particulate matter, nitrogen dioxide (NO 2 ) and ozone are recognized as the three pollutants that most significantly affect human health. Asthma is a multifactorial disease. However, the place of residence has rarely been investigated. We compared the impact of air pollution, measured near patients' homes, on emergency department (ED) visits for asthma or trauma (controls) within the Provence-Alpes-Côte-d'Azur region. Variables were selected using classification and regression trees on asthmatic and control population, 3-99 years, visiting ED from January 1 to December 31, 2013. Then in a nested case control study, randomization was based on the day of ED visit and on defined age groups. Pollution, meteorological, pollens and viral data measured that day were linked to the patient's ZIP code. A total of 794,884 visits were reported including 6250 for asthma and 278,192 for trauma. Factors associated with an excess risk of emergency visit for asthma included short-term exposure to NO 2 , female gender, high viral load and a combination of low temperature and high humidity. Short-term exposures to high NO 2 concentrations, as assessed close to the homes of the patients, were significantly associated with asthma-related ED visits in children and adults.

    Responses to the questionnaire on the diagnosis, patient education and management of asthma indicated that a reduced number of patients with severe asthma were seen in 1993 in both Pediatric and Internal Medicine Departments compared with 5 years before, despite the increase in total number of asthma patients in Japan. Specifiic IgE radioallergosorbent test (RAST measurements were frequently performed instead of skin testing for diagnosis, and eosinophil count and bronchodilator response served as an adjunct to the diagnosis. Patients were frequently asked detailed questions about aspirin-induced asthma, which accounted for 8.8, 2.2 and 1.5% of patients with asthma in the adult, schoolchildren (6–16 years and infant (≤ 5 years groups, respectively. In achieving ‘control of asthma’, first priority was given to coping with the symptoms in children aged 5 years or less and to enabling routine daily life activities in patients 6 years of age or older. Usefulness of peak flow measurements was widely recognized and a detailed plan for allergen avoidance (house dust was often given to patients.

    The significance of oxidative stress in pathogenesis of childhood asthma was recognized, but its role in the clinical manifestations of disease is still unclear. The study was conducted in 96 asthmatic children. The urinary biomarker of oxidative stress, 8-oxo-7,8-dihydro-2-deoxyguanosine (8-oxodG/creatinine) was determined by using HPLC-MS/MS. ELISA was performed to measure myeloperoxidase (MPO) and Cu,Zn- superoxide dismutase (Cu,Zn-SOD) in serum. Logistic regression analysis revealed that female gender, tobacco smoke exposure, and increased 8-oxodG/creatinine were associated with risk for intermittent asthma, while the positive allergy test and increased Cu,Zn-SOD were associated with eczema in asthmatic children. Higher MPO (p = 0.033), and percent of granulocytes (p = 0.030) were found in severe persistent asthma in comparison to intermittent or mild persistent asthma. The main findings that TSE-induced oxidative stress is a risk for intermittent asthma and eczema may be clinically significant for the disease prevention and therapeutic improvements.

    Directory of Open Access Journals (Sweden)

    André Schultz

    2013-01-01

    Full Text Available The principal aims of asthma management in childhood are to obtain symptom control that allows individuals to engage in unrestricted physical activities and to normalize lung function. These aims should be achieved using the fewest possible medications. Ensuring a correct diagnosis is the first priority. The mainstay of asthma management remains pharmacotherapy. Various treatment options are discussed. Asthma monitoring includes the regular assessment of asthma severity and asthma control, which then informs decisions regarding the stepping up or stepping down of therapy. Delivery systems and devices for inhaled therapy are discussed, as are the factors influencing adherence to prescribed treatment. The role of the pediatric health care provider is to establish a functional partnership with the child and their family in order to minimize the impact of asthma symptoms and exacerbations during childhood.

    Tip-enhanced Raman scattering microscopy, a family of scanning probe microscopy techniques, has been recognized as a powerful surface analytical technique with both single-molecule sensitivity and angstrom-scale spatial resolution. This review covers the current status of tip-enhanced Raman scattering microscopy in surface and material nanosciences, including a brief history, the basic principles, and applications for the nanoscale characterization of a variety of nanomaterials. The focus is on the recent trend of combining tip-enhanced Raman scattering microscopy with various external stimuli such as pressure, voltage, light, and temperature, which enables the local control of the molecular properties and functions and also enables chemical reactions to be induced on a nanometer scale.

    1984-01-01

    For large components machining as components of a pressurized water reactor, it is necessary to have means allowing to present them in a position determined with regard to the machine tool used. The aim of the invention is a tipping device which consists of a base resting on the ground, a support-table mounted on this base, moving in rotation with the aid of at least a pivot joint of which axis is horizontal and parallel to the table and a gear pivot allowing to get a very good precision for the orientation of the piece and a very good stability whatever the orientation may be. The output shaft pinion of the base meshes with a gear wheel segment fixed to the table structure. Safety straps fasten the table structure to the base, as they are secured by horizontal pins. The toe pins run in straight slot holes incorporated in base jaws. The table rotation may be controlled by a spring-loaded braking mechanism which acts on the pivot axis and can be released by a hydraulic jack. The hydraulic pressure is used to prevent motor operation, unless the brakes have been released [fr

  13. Tipping Points, Great and Small

    2010-12-01

    The Forum by Jordan et al. [2010] addressed environmental problems of various scales in great detail, but getting the critical message through to the formulators of public policies requires going back to basics, namely, that exponential growth (of a population, an economy, or most anything else) is not sustainable. When have you heard any politician or economist from anywhere across the ideological spectrum say anything other than that more growth is essential? There is no need for computer models to demonstrate “limits to growth,” as was done in the 1960s. Of course, as one seeks more details, the complexity of modeling will rapidly outstrip the capabilities of both observation and computing. This is common with nonlinear systems, even simple ones. Thus, identifying all possible “tipping points,” as suggested by Jordan et al. [2010], and then stopping just short of them, is impractical if not impossible. The main thing needed to avoid environmental disasters is a bit of common sense.

    Objectives: This study evaluates social, behavioral, and environmental determinants to differentiate between active and inactive asthma and how predisposing, enabling, and need factors elucidate asthma-related health services and asthma control among women in Puerto Rico. Methods: This study analyzed secondary cross-sectional data from a subsample of 625 adult females who participated in the Asthma Call Back Survey in Puerto Rico. Logistic and multinomial regression analyses were conducted to examine associations between explanatory variables and asthma outcomes. Results: In total, 63% of women reported active asthma, from which 37.9% have not well controlled or very poorly controlled asthma. Women with active asthma were significantly more likely to be out of work, have middle income (US$25,000–asthma were significantly associated with increased units of physician urgent visits and emergency room visits. Conclusion: The findings confirmed significant determinants for active asthma and adds information on odds ratio for sensitive subgroups that utilize asthma-related health services in higher proportion than their counterparts. These associations suggest a development of asthma management plan targeting women to control the condition and reduce health-care utilization.

    Perinatal programming is an emerging theory for the fetal origins of chronic disease. Maternal asthma and environmental tobacco smoke (ETS) are two of the best-known triggers for the perinatal programming of asthma, while the potential role of maternal diabetes has not been widely studied. To determine if maternal diabetes is associated with child asthma, and if so, whether it modifies the effects of ETS exposure and maternal asthma. We studied 3,574 Canadian children, aged 7-8 years, enrolled in a population-based birth cohort. Standardized questionnaires were completed by the children's parents, and data were analyzed by multivariable logistic regression. Asthma was reported in 442 children (12.4%). Compared to those without asthma, asthmatic children were more likely to have mothers (P = 0.003), but not fathers (P = 0.89), with diabetes. Among children without maternal history of diabetes, the likelihood of child asthma was 1.4-fold higher in those exposed to ETS (adjusted odds ratio, 1.40; 95% confidence interval, 1.13-1.73), and 3.6-fold higher in those with maternal asthma (3.59; 2.71-4.76). Among children born to diabetic mothers, these risks were amplified to 5.7-fold (5.68; 1.18-27.37) and 11.3-fold (11.30; 2.26-56.38), respectively. In the absence of maternal asthma or ETS, maternal diabetes was not associated with child asthma (0.65, 0.16-2.56). Our findings suggest that maternal diabetes may contribute to the perinatal programming of child asthma by amplifying the detrimental effects of ETS exposure and maternal asthma.

    Asthma is a very common chronic disease that occurs in all age groups and is the focus of various clinical and public health interventions. Both morbidity and mortality from asthma are significant. The number of disability-adjusted life years (DALYs) lost due to asthma worldwide is similar to that for diabetes, liver cirrhosis and schizophrenia. Asthma management plans have, however, reduced mortality and severity in countries where they have been applied. Several barriers reduce the availability, affordability, dissemination and efficacy of optimal asthma management plans in both developed and developing countries. The workplace environment contributes significantly to the general burden of asthma. Patients with occupational asthma have higher rates of hospitalization and mortality than healthy workers. The surveillance of asthma as part of a global WHO programme is essential. The economic cost of asthma is considerable both in terms of direct medical costs (such as hospital admissions and the cost of pharmaceuticals) and indirect medical costs (such as time lost from work and premature death). Direct costs are significant in most countries. In order to reduce costs and improve quality of care, employers and health plans are exploring more precisely targeted ways of controlling rapidly rising health costs. Poor control of asthma symptoms is a major issue that can result in adverse clinical and economic outcomes. A model of asthma costs is needed to aid attempts to reduce them while permitting optimal management of the disease. This paper presents a discussion of the burden of asthma and its socioeconomic implications and proposes a model to predict the costs incurred by the disease.

  7. Recent advances in asthma genetics

    Full Text Available Abstract There are over 100 genes that have been reported to be associated with asthma or related phenotypes. In 2006–2007 alone there were 53 novel candidate gene associations reported in the literature. Replication of genetic associations and demonstration of a functional mechanism for the associated variants are needed to confirm an asthma susceptibility gene. For most of the candidate genes there is little functional information. In a previous review by Hoffjan et al. published in 2003, functional information was reported for 40 polymorphisms and here we list another 22 genes which have such data. Some important genes such as filaggrin, interleukin-13, interleukin-17 and the cysteinyl leukotriene receptor-1 which not only were replicated by independent association studies but also have functional data are reviewed in this article.

    Rhinitis is extremely common during pregnancy, and asthma is one of the most common potentially serious medical problems to complicate pregnancy. Cutaneous allergy (urticaria/angioedema and eczema) also may occur during pregnancy. All of these entities may worsen with pregnancy in some patients and appear to improve in others. Uncontrolled asthma may directly threaten the fetus, and morbidity from the other illnesses may indirectly affect pregnancy through an effect on eating, sleeping, or emotional well-being. Appropriate diagnosis, avoiding triggering factors when possible; appropriate use of pharmacotherapy; and, when indicated, allergen immunotherapy usually allow these chronic conditions to be controlled during pregnancy so as to optimize both the health of the mother and that of her baby.

    In assessing acute asthma, the physician must seek specific historical features, symptoms and physical findings. Recent work has shown, however, that while these features are associated with severity, their absence does not imply benignity. Objective measures of pulmonary function are required for accurate assessment of severity. A sequential treatment regimen using nebulized bronchodilators, vigorous rehydration, aminophylline, and corticosteroids should be employed. Status asthmaticus may r...

  11. Environmental tobacco smoke and childhood asthma

    2010-02-01

    Full Text Available In recent years, environmental tobacco smoke (ETS has become an important worldwide public health issue. Children are particularly vulnerable to ETS because they are still developing. ETS exposure causes a wide range of adverse health effects on childhood asthma. There is convincing evidence that ETS exposure is causally associated with an increased prevalence of asthma, increased severity of asthma and worsening asthma control in children who already have the disease, even though a causal relationship with asthma onset is not yet established for asthma incidence. Mechanisms underlying these adverse effects of ETS are not clearly elucidated but e studies on this issue suggest that genetic susceptibility, impaired lung function, and augmented airway inflammation and remodeling may be involved. Children with asthma are just as likely to be exposed to ETS as children in general and there is no risk-free level of exposure. Therefore, providing a smoke-free environment may be of particular importance to the asthmatic children exposed to ETS who have adverse asthma outcomes, as well as to children with genetic susceptibility who are at increased risk of developing asthma upon exposure to ETS in early childhood.

    Full Text Available Introduction. Parental perceptions and practices are important for improving the asthma outcomes in children; indeed, evidence shows that parents of asthmatic children harbor considerable misperceptions of the disease. Objective. To investigate the perceptions and practices of parents toward asthma and its management in Saudi children. Methods. Using a self-administered questionnaire, a two-stage cross-sectional survey of parents of children aged between 3 and 15 years, was conducted from schools located in Riyadh province in central Saudi Arabia. Results. During the study interval, 2000 parents were asked to participate in the study; 1450 parents responded, of whom 600 (41.4% reported that their children had asthma, dyspnea, or chest allergy (recurrent wheezing or coughing, while 478 (32.9% of the parents reported that their children were diagnosed earlier with asthma by a physician. Therefore, the final statistical analyses were performed with 600 participants. Furthermore, 321 (53.5% respondents believed that asthma is solely a hereditary disease. Interestingly, 361 (60.3% were concerned about side effects of inhaled corticosteroids and 192 (32% about the development of dependency on asthma medications. Almost 76% of parents had previously visited a pediatric emergency department during an asthma attack. Conclusions. Parents had misperceptions regarding asthma and exhibited ineffective practices in its management. Therefore, improving asthma care and compliance requires added parental education.

    Asthma is the commonest pre-existing medical condition to complicate pregnancy. Acute severe asthma in pregnancy is rare, but poses difficult problems. In particular, the decision about when and where to deliver the fetus is complex, since maternal response to asthma treatment is unpredictable. We report the successful management of a parturient presenting with acute severe asthma at 37 weeks' gestation. The controversies involved and the importance of adopting a multi-disciplinary team approach to optimise maternal and neonatal outcomes are discussed.

    Over 20 million Americans are affected with asthma. Many will require some type of surgical procedure during which their asthma management should be optimized. Preoperative assessment of asthma should include a specialized history and physical as well as pulmonary function testing. In many asthmatic patients, treatment with systemic corticosteroids and bronchodilators is indicated to prevent the inflammation and bronchoconstriction associated with endotracheal intubation. The use of corticosteroids has not been shown to adversely affect wound healing or increase the rate of infections postoperatively. Preoperative systemic corticosteroids may be used safely in the majority of patients to decrease asthma-related morbidity.

    The Japanese Guideline for the Diagnosis and Treatment of Allergic Diseases 2017 (JAGL 2017) includes a minor revision of the Japanese Pediatric Guideline for the Treatment and Management of Asthma 2012 (JPGL 2012) by the Japanese Society of Pediatric Allergy and Clinical Immunology. The section on child asthma in JAGL 2017 provides information on how to diagnose asthma between infancy and adolescence (0-15 years of age). It makes recommendations for best practices in the management of childhood asthma, including management of acute exacerbations and non-pharmacological and pharmacological management. This guideline will be of interest to non-specialist physicians involved in the care of children with asthma. JAGL differs from the Global Initiative for Asthma Guideline in that JAGL emphasizes diagnosis and early intervention of children with asthma at asthma control levels, is easy to understand; thus, this guideline is suitable for the routine medical care of children with asthma. JAGL also recommends using a control test in children, so that the physician aims for complete control by avoiding exacerbating factors and appropriately using anti-inflammatory drugs (for example, inhaled corticosteroids and leukotriene receptor antagonists).

    A unified approach to innovation is needed to address the challenge of asthma in Europe. It is the opinion of the EARIP consortium and associated members (comprising most asthma networks, societies and professional groups) that if all of these research priority areas were funded and the 15 research...... questions addressed, asthma outcomes would be transformed and avoidable use of healthcare systems eradicated, resulting in significant financial savings. The realisation of this vision through coordinated efforts at a European level is the only way to achieve the change needed to reduce asthma deaths...

    This study examines the relationship between children's abilities to perceive their symptoms of asthma via several previously researched subjective and objective procedures compared with their performance on a standardized children's drawing task and scale criteria. Results indicated that girls verbalized significantly more emotions about their drawings and were better able to detect airflow changes in their small airways than boys. The Gabriels Asthma Perception Drawing Scales (GAPDS) is a promising clinical tool for assessing children's perceptions and emotions about asthma via nonverbal methods. Varying methods of measuring asthma symptom awareness are not highly correlated; thus, more than one methodology is appropriate for use with children.

    The relationship between sex hormones and asthma has been evaluated in several studies. The aim of this review article was to investigate the association between asthma and female sex hormones, under different conditions (premenstrual asthma, use of oral contraceptives, menopause, hormone replacement therapy and pregnancy). Narrative review of the medical literature, Universidade Federal do Tocantins (UFT) and Universidade Federal de São Paulo (Unifesp). We searched the CAPES journal portal, a Brazilian platform that provides access to articles in the MEDLINE, PubMed, SciELO, and LILACS databases. The following keywords were used based on Medical Subject Headings: asthma, sex hormones, women and use of oral contraceptives. The associations between sex hormones and asthma remain obscure. In adults, asthma is more common in women than in men. In addition, mortality due to asthma is significantly higher among females. The immune system is influenced by sex hormones: either because progesterone stimulates progesterone-induced blocking factor and Th2 cytokines or because contraceptives derived from progesterone and estrogen stimulate the transcription factor GATA-3. The associations between asthma and female sex hormones remain obscure. We speculate that estrogen fluctuations are responsible for asthma exacerbations that occur in women. Because of the anti-inflammatory action of estrogen, it decreases TNF-α production, interferon-γ expression and NK cell activity. We suggest that further studies that highlight the underlying physiopathological mechanisms contributing towards these interactions should be conducted.
