Assess the relationship between inhaled corticosteroid use (ICS) and weight (BMI) in pediatric patients with moderate-severe asthma. Assess if the number of emergency department (ED) visits correlates with overall BMI trajectory. Assess the trend of prescribing biologic therapy in pediatric patients with moderate-severe asthma and determine its relationship with weight (BMI). A retrospective chart review was performed on 93 pediatric patients with moderate-severe asthma to determine the relationship between ICS use and weight (BMI), biologic therapy and BMI, and number of ED visits and BMI trajectory. A mixed effects model was employed with the correlation between repeated measures accounted for through the random effects. There is a statistically significant increase of 0.369 kg/m 2 in BMI trajectory per year in subjects on high-dose steroids compared to an increase of 0.195 kg/m 2 in the low dose group (p BMI of subjects initiated on biologic therapy (omalizumab or mepolizumab) had a statistically significant decrease in BMI trajectory of 0.818 kg/m 2 per year (p BMI trajectory (p BMI trajectory; the higher the dose, the greater the projected BMI increase per year. Initiation of biologic therapy decreased BMI trajectory over time. Lastly, those with frequent ED visits had a higher BMI trend. Future prospective studies are warranted that further evaluate the potential metabolic impacts of ICS and assess the effects of biologic therapy on BMI.
Full Text Available The search for the new noninvasive and information methods to estimate the intensity of the inflammatory processes during the bronchial asthma is an important task for the modern medicine, pediatrics, in particular. We have examined 20 children, suffering from moderately severe bronchial asthma in remission. patients underwent the induction of the sputum by means of nail hypertonic solution, bronchoscopic examination along with the sampling of the lavage fluid and bronchial biopsy, cytometry of the induced sputum and bronchoalveolar lavage fluid, morphometric examination of the biopsy samples of bronchi walls, determination of the nitric oxide contents in the expired air. We revealed high self descriptiveness of the cytological characteristics of the induced sputum. High percentage of neutrophiles and eosinophiles in the induced sputum disclosed during remission of the bronchial asthma, as well as thickness increase of the basilemma, ratio distortion of the ciliated and cyathiform cells in the favor of the latter, especially along with the high nitric oxide contents in the expired air indicate the continuous persistence in the allergic respiratory inflammation.Key words: induced sputum, bronchial asthma, children.
Full Text Available Background/Aim: The incidence of bronchial asthma is on increase. Chemotherapy is helpful during early course of the disease, but later on morbidity and mortality increases. The efficacy of yoga therapy though appreciated is yet to be defined and modified. Aim: To study the effect of breathing exercises ( pranayama in patients with bronchial asthma of mild to moderate severity. Materials and Methods: Fifty cases of bronchial asthma (Forced Expiratory Volume in one second (FEV1 > 70% were studied for 12 weeks. Patients were allocated to two groups: group A and group B (control group. Patients in group A were treated with breathing exercises (deep breathing, Brahmari , and Omkara , etc. for 20 minutes twice daily for a period of 12 weeks. Patients were trained to perform Omkara at high pitch (forceful with prolonged exhalation as compared to normal Omkara . Group B was treated with meditation for 20 minutes twice daily for a period of 12 weeks. Subjective assessment, FEV1%, and Peak Expiratory Flow Rate (PEFR were done in each case initially and after 12 weeks. Results: After 12 weeks, group A subjects had significant improvement in symptoms, FEV1, and PEFR as compared to group B subjects. Conclusion: Breathing exercises ( pranayama , mainly expiratory exercises, improved lung function subjectively and objectively and should be regular part of therapy.

Full Text Available OBJECTIVE:to compare physical performance and cardiorespiratory responses in the six-minute walk test (6MWT in asthmatic children with reference values for healthy children in the same age group, and to correlate them with intervening variables.METHODS:this was a cross-sectional, prospective study that evaluated children with moderate/severe asthma, aged between 6 and 16 years, in outpatient follow-up. Demographic and spirometric test data were collected. All patients answered the pediatric asthma quality of life (QoL questionnaire (PAQLQ and level of basal physical activity. The 6MWT was performed, following the American Thoracic Society recommendations. Comparison of means was performed using Student's t-test and Pearson's correlation to analyze the 6MWT with study variables. The significance level was set at 5%.RESULTS:40 children with moderate or severe asthma were included, 52.5% males, 70% with normal weight and sedentary. Mean age was 11.3 ± 2.1 years, mean height was 1.5 ± 0.1 m, and mean weight was 40.8 ± 12.6 Kg. The mean distance walked in the 6MWT was significantly lower, corresponding to 71.9% ± 19.7% of predicted values; sedentary children had the worst values. The difference between the distance walked on the test and the predicted values showed positive correlation with age (r = 0.373, p = 0.018 and negative correlation with cardiac rate at the end of the test (r = -0.518, p < 0.001. Regarding QoL assessment, the values in the question about physical activity limitations showed the worst scores, with a negative correlation with walked distance difference (r = -0.311, p = 0.051.CONCLUSIONS:asthmatic children's performance in the 6MWT evaluated through distance walked is significantly lower than the predicted values for healthy children of the same age, and is directly influenced by sedentary life style.

Differences between the opinions of patients and physicians on the impact of asthma are common. We hypothesised that patient-physician discordance may negatively affect asthma outcome. A total of 2902 patients (61% women, mean age 47 years) with moderate-severe asthma and 231 physicians participated in a prospective study. At the baseline visit, data on demographics, clinical variables, degree of asthma control according to the Asthma Control Test (ACT), basic spirometry and the Hospital Anxiety and Depression Scale (HADS) were collected and an ad hoc questionnaire was completed that allowed the degree of concordance between doctors and patients to be assessed. A scheduled telephone call after 3 months was used to elicit the ACT score and the future risk of asthma. At the final visit at 6 months, the following data were recorded: ACT score, spirometry, HADS score and an ad hoc questionnaire to assess the agreement between the doctor and the patient. Changes in study variables according to patient-physician concordance or discordance were analysed. The rate of patient-physician discordance was 27.2%, with overestimation of disease impact by the physician in 12.3% and underestimation in 14.9%. Patient-physician opinion discordance, particularly in the case of physicians underestimating the impact of asthma, showed worse results with statistically significant differences in ACT score, a higher percentage of patients with poor asthma control and lower HADS scores. The need for hospital and emergency department admissions was also higher. Patient-physician opinion discordance may be contributing to lower symptomatic control and increased future risk, with a higher impact when physicians underestimate the impact of asthma on their patients.
Moderate severity asthma occurs in approximately 10 to 15% of patients with chronic reversible airway obstruction and is de- fined by more than four daytime symptoms per week, more than four night time symptoms per month and peak expiratory flow rates of between 60 and 80% of predicted values.

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.

Full Text Available Hallux valgus is one of the commonest conditions of the foot and has been reported to affect nearly half of the adult population. It is most effectively treated by a corrective osteotomy of which there a numerous subtypes. The Mau osteotomy confers the greatest structural stability but is not thought to provide adequate correction of moderate-severe deformities. Accordingly, complications such as under correction and non-union are common. The aim of this study was to determine the functional outcome in patients with moderate-severe hallux valgus following a Mau osteotomy. A retrospective review of 23 patients with moderate-severe hallux valgus treated by Mau osteotomy was conducted. Patients were assessed clinically by the American Orthopedic Foot and Ankle Society (AOFAS scoring system and radiologically by measuring the first intermetatarsal (IM and hallux abductovalgus angles (HAV. The mean AOFAS score had improved from 47 preoperatively to 92 postoperatively (P<0.01. Additionally, preoperative HAV and IM angles improved from 39° and 15° respectively to 15° and 9° respectively (P<0.01. There were no cases of undercorrection or non-union. In this series, the Mau osteotomy was able to achieve good correction of the IM and HAV angles in patients with moderate-severe hallux valgus. This was reflected in a significantly higher postoperative AOFAS score. Contrary to other studies there were no cases of undercorrection and despite allowing patients to fully weight-bear postoperatively there were no cases of non-union.

According to the revised Atlanta classification, severe and moderately severe acute pancreatitis (AP) includes patients with pancreatic and peripancreatic collections with or without organ failure. These collections suggest the presence of pancreatic juice leakage. The aim of this study was to evaluate the efficacy of a percutaneous catheter drainage (PCD) protocol designed to control leakage and decrease disease severity. Among 663 patients with clinical AP, 122 were classified as moderately severe or severe AP (all had collections). The computed tomography severity index (CTSI) score was calculated. The indication for PCD was based on progressive clinical signs and symptoms. Drain patency, position, and need for additional drainage sites were assessed using CT scans and drain studies initially every 3 days using a proactive protocol. Drain fluid was examined for amylase concentration and microbiological culture. Clinicopathological variables for patients with and without PCD were compared. Since there was no mortality, we used prolonged drainage time to measure the success of PCD. Within the group treated with PCD, variables that resulted in prolonged drainage time were analyzed. PCD was used in 47/122 (39 %) patients of which 33/47 (70 %) had necrosis. PCD cases had a median CTSI of 8 and were classified as moderately severe AP (57 %) and severe AP (43 %). Inhospital mortality was zero. Surgical necrosectomy was not required for patients with necrosis. Independent risk factors for prolonged drainage time were persistent organ failure >48 h (P = 0.001), CTSI 8-10 (P = 0.038), prolonged duration of amylase-rich fluid in drains (P drainage fluid resulting in a mortality rate of zero.

This report describes improved signs and symptoms of previously untreated symptomatic spinal deformity in an adult female diagnosed with moderately severe thoracic scoliosis at the age of .7 years. Current treatment initiated at the age of forty included massage therapy, manual traction, ischemic pressure, and comprehensive manipulative medicine (CMM). A left-right chest circumference inequity was reduced by >10 cm, in correlation with improved appearance of the ribcage deformity and a 40% reduction in magnitude of Cobb angle, which had been stable for 30 years. The changes occurred gradually over an eight-year period, with the most rapid improvement occurring during two periods when CMM was employed.

Cognitive environmental enrichment (C-EE) offers promise for offsetting neural decline that is observed in chronic moderate-severe traumatic brain injury (TBI). Brain games are a delivery modality for C-EE that can be self-administered over the Internet without therapist oversight. To date, only one study has examined the feasibility of self-administered brain games in TBI, and the study focused predominantly on mild TBI. Therefore, the primary purpose of the current study was to examine the feasibility of self-administered brain games in moderate-severe TBI. A secondary and related purpose was to examine the feasibility of remote monitoring of any C-EE-induced adverse symptoms with a self-administered evaluation tool. Ten patients with moderate-severe TBI were asked to complete 12 weeks (60 min/day, five days/week) of online brain games with bi-weekly self-evaluation, intended to measure any adverse consequences of cognitive training (e.g., fatigue, eye strain). There was modest weekly adherence (42.6% ± 4.4%, averaged across patients and weeks) and 70% patient retention; of the seven retained patients, six completed the self-evaluation questionnaire at least once/week for each week of the study. Even patients with moderate-severe TBI can complete a demanding, online C-EE intervention and a self-administered symptom evaluation tool with limited therapist oversight, though at daily rate closer to 30 than 60 min per day. Further self-administered C-EE research is underway in our lab, with more extensive environmental support. Implications for Rehabilitation Online brain games (which may serve as a rehabilitation paradigm that can help offset the neurodegeneration observed in chronic TBI) can be feasibly self-administered by moderate-to-severe TBI patients. Brain games are a promising therapy modality, as they can be accessed by all moderate-to-severe TBI patients irrespective of geographic location, clinic and/or therapist availability, or impairments that

We report the clinical, neuroimaging, and neuropathologic characteristics of 2 patients who developed early onset dementia after a moderate-severe traumatic brain injury (TBI). Neuropathological evaluation revealed abundant β-amyloid neuritic and cored plaques, diffuse β-amyloid plaques, and frequent hyperphosphorylated-tau neurofibrillary tangles (NFT) involving much of the cortex, including insula and mammillary bodies in both cases. Case 1 additionally showed NFTs in both the superficial and deep cortical layers, occasional perivascular and depth-of-sulci NFTs, and parietal white matter rarefaction, which corresponded with decreased parietal fiber tracts observed on ex vivo MRI. Case 2 additionally showed NFT predominance in the superficial layers of the cortex, hypothalamus and brainstem, diffuse Lewy bodies in the cortex, amygdala and brainstem, and intraneuronal TDP-43 inclusions. The neuropathologic diagnoses were atypical Alzheimer disease (AD) with features of chronic traumatic encephalopathy and white matter loss (Case 1), and atypical AD, dementia with Lewy bodies and coexistent TDP-43 pathology (Case 2). These findings support an epidemiological association between TBI and dementia and further characterize the variety of misfolded proteins that may accumulate after TBI. Analyses with comprehensive clinical, imaging, genetic, and neuropathological data are required to characterize the full clinicopathological spectrum associated with dementias occurring after moderate-severe TBI. 2017 American Association of Neuropathologists, Inc.

The Dependence Scale (DS) was designed to measure dependence on others among patients with Alzheimer's disease (AD). The objectives of this research were primarily to strengthen the psychometric evidence for the use of the DS in AD studies. Patients with mild to moderately severe AD were examined in 3 study databases. Within each data set, internal consistency, validity, and responsiveness were examined, and structural equation models were fit. The DS has strong psychometric properties. The DS scores differed significantly across known groups and demonstrated moderate to strong correlations with measures hypothesized to be related to dependence (|r| ≥ .31). Structural equation modeling supported the validity of the DS concept. An anchor-based DS responder definition to interpret a treatment benefit over time was identified. The DS is a reliable, valid, and interpretable measure of dependence associated with AD and is shown to be related to--but provides information distinct from--cognition, functioning, and behavior.

Full Text Available MODERATE-severe depression (MSD is linked to overexpression of proinflammatory cytokines and chemokines. Fractalkine (FKN and macrophage inflammatory protein-1 alpha (MIP-1α are, respectively, members of CX3C and C-C chemokines, and both are involved in recruiting and activating mononuclear phagocytes in the central nervous system. We analysed the presence of FKN and MIP-1α in sera of untreated MSD patients and healthy donors. High FKN levels were observed in all MSD patients as compared with values only detectable in 26% of healthy donors. MIP-1α was measurable in 20% of patients, while no healthy donors showed detectable chemokine levels. In conclusion, we describe a previously unknown involvement of FKN in the pathogenesis of MSD, suggesting that FKN may represent a target for a specific immune therapy of this disease.

Bark beetle outbreaks in Western North American forests are often considered a high-severity disturbance from a carbon (C) cycling perspective, but field measurements that quantify impacts on C dynamics are very limited. Often, factors out of the researcher's control complicate the separation of beetle impacts from other drivers of C cycling variability and restrict statistical inference. Fortuitously, we had four years of pre-spruce beetle outbreak C cycle measurements in a subalpine forest in southeastern Wyoming (Glacier Lakes Ecosystem Experiments Site, or GLEES) and sustained intermittent monitoring for nearly a decade after the outbreak. Here, we synthesize published and unpublished pre- and post-outbreak measurements of key C cycle stocks and fluxes at GLEES. Multiple lines of evidence, including chamber measurements, eddy covariance measurements, and tracking of soil and forest floor C pools over time, point to the GLEES outbreak as a moderate-severity disturbance for C loss to the atmosphere, despite 70% to 80% of overstory tree death. Reductions in NEE were short-lived and the forest quickly returned to a carbon-neutral state, likely driven by an uptick in understory growth. Effect of mortality on the C cycle was asymmetrical, with a 50% reduction in net carbon uptake (NEE) two years into the outbreak, yet no measureable change in either ecosystem or growing season soil respiration. A small pulse in soil respiration occurred but was only detectable during the winter and amounted to < 10% of NEE. Possible reasons for the lack of measureable respiration response are discussed with emphasis on lessons learned for monitoring and modeling future outbreaks. We suggest a comprehensive assessment and definition of "moderate-severity" disturbances for Western forests and suggest that all tree mortality events may not be high-severity when it comes to C fluxes.

For asymptomatic patients with moderate-severe valvular heart disease, in whom symptoms may be obscured, objective exercise tolerance measures are warranted for decisions concerning physical activities and surgical treatment. We compared 61 patients (39 with aortic stenosis, 22 with aortic or mitral regurgitation) to 23 controls without valvular heart disease but with indications for stress testing. All participants underwent cardiopulmonary function testing and dobutamine stress echocardiography. Blood was drawn before as well as after bicycle stress to assess high-sensitivity cardiac troponin T (hscTnT). Patients who underwent surgery were re-evaluated 1.5 ±0.9 years after the operation. Conventional bicycle test following guideline criteria revealed a pathologic result in 26% of the patients, whereas spiroergometry showed an objectively reduced exercise tolerance in 59%, reaching a prognostically relevant feature in 39%. Stress echocardiography detected a reduced systolic reserve in 33% and elevated filling pressures in 62%. These abnormalities were significantly less present in the control group (4, 17, 9, 9, 4% respectively, p valvular heart disease beyond stress-test criteria recommended in recent guidelines. High-sensitivity cardiac troponin I may be of additional value. Results of these tests presage post-operative function.

Full Text Available Traumatic brain injury (TBI is the leading cause of death and disability in children and can lead to a wide range of impairments. Brain imaging methods such as DTI (diffusion tensor imaging are uniquely sensitive to the white matter (WM damage that is common in TBI. However, higher-level analyses using tractography are complicated by the damage and decreased FA (fractional anisotropy characteristic of TBI, which can result in premature tract endings. We used the newly developed autoMATE (automated multi-atlas tract extraction method to identify differences in WM integrity. 63 pediatric patients aged 8–19 years with moderate/severe TBI were examined with cross sectional scanning at one or two time points after injury: a post-acute assessment 1–5 months post-injury and a chronic assessment 13–19 months post-injury. A battery of cognitive function tests was performed in the same time periods. 56 children were examined in the first phase, 28 TBI patients and 28 healthy controls. In the second phase 34 children were studied, 17 TBI patients and 17 controls (27 participants completed both post-acute and chronic phases. We did not find any significant group differences in the post-acute phase. Chronically, we found extensive group differences, mainly for mean and radial diffusivity (MD and RD. In the chronic phase, we found higher MD and RD across a wide range of WM. Additionally, we found correlations between these WM integrity measures and cognitive deficits. This suggests a distributed pattern of WM disruption that continues over the first year following a TBI in children.

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.

Abstract Traumatic brain injury leads to significant loss of brain volume, which continues into the chronic stage. This can be sensitively measured using volumetric analysis of MRI. Here we: (i) investigated longitudinal patterns of brain atrophy; (ii) tested whether atrophy is greatest in sulcal cortical regions; and (iii) showed how atrophy could be used to power intervention trials aimed at slowing neurodegeneration. In 61 patients with moderate-severe traumatic brain injury (mean age = 41.55 years ± 12.77) and 32 healthy controls (mean age = 34.22 years ± 10.29), cross-sectional and longitudinal (1-year follow-up) brain structure was assessed using voxel-based morphometry on T1-weighted scans. Longitudinal brain volume changes were characterized using a novel neuroimaging analysis pipeline that generates a Jacobian determinant metric, reflecting spatial warping between baseline and follow-up scans. Jacobian determinant values were summarized regionally and compared with clinical and neuropsychological measures. Patients with traumatic brain injury showed lower grey and white matter volume in multiple brain regions compared to controls at baseline. Atrophy over 1 year was pronounced following traumatic brain injury. Patients with traumatic brain injury lost a mean (± standard deviation) of 1.55% ± 2.19 of grey matter volume per year, 1.49% ± 2.20 of white matter volume or 1.51% ± 1.60 of whole brain volume. Healthy controls lost 0.55% ± 1.13 of grey matter volume and gained 0.26% ± 1.11 of white matter volume; equating to a 0.22% ± 0.83 reduction in whole brain volume. Atrophy was greatest in white matter, where the majority (84%) of regions were affected. This effect was independent of and substantially greater than that of ageing. Increased atrophy was also seen in cortical sulci compared to gyri. There was no relationship between atrophy and time since injury or age at baseline. Atrophy rates were related to memory performance at the end of the

Full Text Available Background. Acetylcholinesterase (AChE/cholinesterase (ChE inhibitors (Is and memantine are licensed for symptomatic treatment of mild-moderate and moderate-severe forms of Alzheimer’s disease (AD, respectively. High doses of the AChE-I donepezil were licensed in the USA for moderate-severe AD, and the association AChE/ChE-Is plus memantine was proposed for AD at this stage. Objectives. This paper has reviewed evidence from clinical trials of the effectiveness of memantine, donepezil, or the two drugs in association in managing moderate-severe AD. Method. Double-blind, placebo-controlled randomized trials (RCTs using memantine or donepezil alone or in association versus placebo in moderate-severe AD were reviewed. Analysis done in January 2013 considered the years 2007–2012. Results and Conclusion. Only 83 of the 941 papers selected were considered relevant, and only 13 met the criterion of “adequacy and representativeness.” Memantine and donepezil lead to improvements in moderate-to-severe AD and the choice between the compounds should be based on their contraindications more than on disease severity. No evidence was found of advantages of the association of memantine-donepezil. The heterogeneity of conditions explored by RCTs, the relatively short time of observation (24–52 weeks, and the different cognitive assessment tools used did not allow comparing properly different trials.

The benefits of treating children at home or in an ambulatory setting have been well documented. We aimed to describe the characteristics and evaluate the outcomes of children with moderate/severe cellulitis treated at home with intravenous (IV) ceftriaxone via direct referral from the Emergency Department to a hospital-in-the-home (HITH) program. Patients aged 3 months to 18 years with moderate/severe cellulitis referred from a tertiary pediatric Emergency Department to HITH from September 2012 to January 2014 were prospectively identified. Data collection included demographics, clinical features, microbiological characteristics and outcomes. To ensure home treatment did not result in inferior outcomes, these patients were retrospectively compared with patients who were hospitalized for IV flucloxacillin, the standard-of-care over the same period. The primary outcome was home treatment failure necessitating hospital admission. Secondary outcomes included antibiotic changes, complications, length of stay and cost. Forty-one (28%) patients were treated on HITH and 103 (72%) were hospitalized. Compared with hospitalized patients, HITH patients were older (P antibiotic changes was similar in both groups (5% vs. 7%, P = 0.67), as was IV antibiotic duration (2.3 vs. 2.5 days, P = 0.23). Older children with moderate/severe limb cellulitis without systemic symptoms can be treated at home. To ascertain if this practice can be applied more widely, a comparative prospective, ideally randomized, study is needed.

The aim of this study was to investigate the relationship between symptom severity, cost, and impairment in women with moderate/severe premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD) in a Latin American setting. A model was constructed based on analysis of an observational dataset. Data were included from four Latin American countries. Responder-level data were analysed according to four categories of symptom severity: Category 1 comprised Daily Record of Severity of Problems score 21 to 41.9, Category 2 score was 42 to 62.9, Category 3 score was 63 to 83.9, and Category 4 was a score of 84 or higher. Burden was estimated in terms of impact on job and activities using the modified work productivity and impairment questionnaire and affect on quality of life using the SF-12 questionnaire. Costs were estimated in Brazilian reals from a Brazilian private health care and societal perspective. The outputs of the analysis were estimates of burden, mean annual cost and affect on quality of life (as measured by quality adjusted life years) by symptom severity. Confidence intervals around key outcomes were generated through nonparametric bootstrapping. Analysis suggests a significant cost burden associated with moderate/severe PMS and PMDD with mean per patient annual costs estimated at 1618 BRL (95% confidence interval 957-2,481). Although the relationship between cost, quality of life, and severity was not clear, analysis showed a consistent relationship between disease severity and measures of disease burden (job and daily activity). Burden on activities increased with disease severity. Our analysis, conducted from a Latin American perspective, suggests a significant burden and an increasing impairment associated with moderate/severe PMS and PMDD.

Full Text Available Abstract Background Balance dysfunction and falls are common problems in later stages of dementia. Exercise is a well-established intervention to reduce falls in cognitively intact older people, although there is limited randomised trial evidence of outcomes in people with dementia. The primary objective of this study is to evaluate whether a home-based balance exercise programme improves balance performance in people with mild to moderate severity Alzheimer's disease. Methods/design Two hundred and fourteen community dwelling participants with mild to moderate severity Alzheimer's disease will be recruited for the randomised controlled trial. A series of laboratory and clinical measures will be used to evaluate balance and mobility performance at baseline. Participants will then be randomized to receive either a balance training home exercise programme (intervention group from a physiotherapist, or an education, information and support programme from an occupational therapist (control group. Both groups will have six home visits in the six months following baseline assessment, as well as phone support. All participants will be re-assessed at the completion of the programme (after six months, and again in a further six months to evaluate sustainability of outcomes. The primary outcome measures will be the Limits of Stability (a force platform measure of balance and the Step Test (a clinical measure of balance. Secondary outcomes include other balance and mobility measures, number of falls and falls risk measures, cognitive and behavioural measures, and carer burden and quality of life measures. Assessors will be blind to group allocation. Longitudinal change in balance performance will be evaluated in a sub-study, in which the first 64 participants of the control group with mild to moderate severity Alzheimer's disease, and 64 age and gender matched healthy participants will be re-assessed on all measures at initial assessment, and then at 6, 12

Since anemia is associated with poor health outcomes, the prevalence of anemia is a significant public health indicator. Even though anemia is primarily caused by iron deficiency, low oxygen-carrying capacity may result from other conditions such as chronic diseases, which remain a relevant health concern in the United States. However, studies examining current rates of anemia in the total US population and in more specific subgroups are limited. Data from five National Health and Nutrition Examination Surveys (NHANES) from 2003 to 2012 were analyzed to assess two outcomes: anemia and moderate-severe anemia, which were based upon serum hemoglobin levels (Hb) as per World Health Organization (WHO) definitions. Statistical analysis using SAS examined temporal trends and the prevalence of anemia among sexes, age groups, and races/ethnicities. The study estimated that an average of 5.6% of the U.S. population met the criteria for anemia and 1.5% for moderate-severe anemia during this 10-year period. High-risk groups such as pregnant women, elderly persons, women of reproductive age, non-Hispanic blacks, and Hispanics were identified, and relationships between multiple risk factors were examined. Rates of anemia in men increased monotonically with age, while that of women increased bimodally with peaks in age group 40–49 years and 80–85 years. The effect of risk factors was observed to compound. For instance, the prevalence of anemia in black women aged 80–85 years was 35.6%, 6.4 times higher than the population average. Moreover, anemia is a growing problem because of the increased prevalence of anemia (4.0% to 7.1%) and moderate-severe anemia (1.0% to 1.9%), which nearly doubled from 2003–2004 to 2011–2012. Thus, these results augment the current knowledge on anemia prevalence, severity, and distribution among subgroups in the US and raised anemia as an issue that requires urgent public health intervention.

Mandibular kinematic and standardized surface electromyography (sEMG) characteristics of masticatory muscles of subjects with short lasting TMD of mild-moderate severity were examined. Volunteers were submitted to clinical examination and questionnaire of severity. Ten subjects with TMD (age 27.3years, SD 7.8) and 10 control subjects without TMD, matched by age, were selected. Mandibular movements were recorded during free maximum mouth opening and closing (O-C) and unilateral, left and right, gum chewing. sEMG of the masseter and temporal muscles was performed during maximum teeth clenching either on cotton rolls or in intercuspal position, and during gum chewing. sEMG indices were obtained. Subjects with TMD, relative to control subjects, had lower relative mandibular rotation at the end of mouth opening, larger mean number of intersection between interincisal O-C paths during mastication and smaller asymmetry between working and balancing side, with participation beyond the expected of the contralateral muscles (Pkinematic parameters and the EMG indices of the static test, although some changes in the mastication were observed.

Full Text Available Abstract Background Abnormal breathing patterns may cause characteristic symptoms and impair quality of life. In a cross-sectional survey 29% of adults treated for asthma in primary care had symptoms suggestive of dysfunctional breathing (DB, more likely to be female and younger, with no differences for severity of asthma. No clear risk factors were demonstrated for DB in asthma, nor the impact of asthma medication was evaluated. The objective of this study was to describe the DB phenotype in adults with asthma treated in a specialised asthma centre. Methods Adult patients aged 17–65 with diagnosed asthma were screened for DB using the Nijmegen questionnaire (positive predictive score >23 and confirmed by progressive exercise testing. The following were evaluated as independent risk factors for DB in the multiple regression analysis: female sex; atopy, obesity, active smoker, moderate/severe rhinitis, psychopathology, GERD, arterial hypertension; severe asthma, asthma duration > 5 years, lack of asthma control, fixed airway obstruction, fast lung function decline, frequent exacerbator and brittle asthma phenotypes; lack of ICS, use of LABA or LTRA. Results 91 adults with asthma, mean age 35.04 ±1.19 years, 47(51.65% females were evaluated. 27 (29.67% subjects had a positive screening score on Nijmegen questionnaire and 16(17.58% were confirmed by progressive exercise testing as having DB. Independent risk factors for DB were psychopathology (p = 0.000002, frequent exacerbator asthma phenotype (p = 0.01 and uncontrolled asthma (p Conclusion Dysfunctional breathing is not infrequent in asthma patients and should be evaluated in asthma patients presenting with psychopathology, frequent severe asthma exacerbations or uncontrolled asthma. Asthma medication (ICS, LABA or LTRA had no significant relation with dysfunctional breathing.

Nutrition is the major environmental factor that influences the risk of developing pathologies, such as obesity. Although a number of recent reviews pinpoint a protective effects of milk on body weight and obesity related co-morbidities, an inaccurate estimate of milk might contribute to hamper its beneficial effects on health outcomes. Seven-day food records provide prospective food intake data, reducing recall bias and providing extra details about specific food items. Milk intake stimulates the somatotropic axis at multiple levels by increasing both growth hormone (GH) and insulin-like growth factor-1 (IGF-1) secretion. On the other hand, obesity is associated with reduced spontaneous and stimulated GH secretion and basal IGF-1 levels. Aim of this study was to evaluate the milk consumption by using the 7-days food record in obese individuals and to investigate the association between milk intake and GH secretory status in these subjects. Cross-sectional observational study carried out on 281 adult individuals (200 women and 81 men, aged 18-74 years) with moderate-severe obesity (BMI 35.2-69.4 kg/m 2 ). Baseline milk intake data were collected using a 7 day food record. Anthropometric measurements and biochemical profile were determined. The GH/IGF-1 axis was evaluated by peak GH response after GHRH + ARGININE and IGF-1 standard deviation score (SDS). The majority of individuals (72.2%) reported consuming milk; 250 mL low-fat milk was the most frequently serving of milk consumed, while no subjects reported to consume whole milk. Milk consumers vs no milk consumers presented the better anthropometric measurements and metabolic profile. At the bivariate proportional odds ratio model, after adjusting for BMI, age and gender, milk consumption was associated the better GH status (OR = 0.60; p milk consumers, subjects consuming 250 mL reduced-fat milk vs 250 mL low-fat milk presented the better anthropometric measurements and metabolic profile.

Full Text Available The incidence of hypertriglyceridemia induced acute pancreatitis (HTAP continues to rise in China. It has systemic complications and high mortality, making the early assessment of the severity of this disease even more important. Circulating microRNAs (miRNAs could be novel, non-invasive biomarkers for disease progression judgment. This study aimed to identify the potential role of serum miRNAs as novel biomarkers of HTAP progression. HTAP patients were divided into two groups: moderately severe (HTMSAP and severe (HTSAP, healthy people were used as control group. The serum miRNA expression profiles of these three groups were determined by microarray and verified by qRT-PCR. The functions and pathways of the targeted genes of deregulated miRNAs were predicted, using bioinformatics analysis; miRNA-mRNA network was generated. Moreover, the correlation between miR-181a-5p and pancreatitis metabolism related substances were studied and the serum concentration of inflammatory cytokines and miRNAs at different time points during the MSAP and SAP were investigated, respectively. Finally, the receiver operating characteristic (ROC curve of miRNAs was studied. Significant changes in the serum concentration of the following miRNAs of HTAP patients (P<0.05 were discovered: miR24-3p, 361-5p, 1246, and 222-3p (constantly upregulated, and 181a-5p (constantly downregulated (P<0.05. Bioinformatics analysis predicted that 13 GOs and 36 pathways regulated by overlap miRNAs were involved in glucose, fat, calcium (Ca++, and insulin metabolism (P<0.001. miRNA-mRNA network revealed that the overlap miRNAs targeted genes participating in pancreas metabolism and miR-181a-5p, the only downregulated miRNA, had good negative correlation with triglyceride (TG, total cholesterol (TC, and fast blood glucose (FBG, but a positive correlation with Ca++. When compared with inflammatory cytokines, the changes of all five overlap miRNAs were more stable. It was found that when

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.

Retrospective secondary analysis of data. To investigate the external validity of the whiplash clinical prediction rule (CPR). We recently derived a whiplash CPR to consolidate previously established prognostic factors for poor recovery from a whiplash injury and predicted 2 recovery pathways. Prognostic factors for full recovery were being less than 35 years of age and having an initial Neck Disability Index (NDI) score of 32% or less. Prognostic factors for ongoing moderate/severe pain and disability were being 35 years of age or older, having an initial NDI score of 40% or more, and the presence of hyperarousal symptoms. Validation is required to confirm the reproducibility and accuracy of this CPR. Clinician feedback on the usefulness of the CPR is also important to gauge acceptability. A secondary analysis of data from 101 individuals with acute whiplash-associated disorder who had previously participated in either a randomized controlled clinical trial or prospective cohort study was performed using accuracy statistics. Full recovery was defined as NDI score at 6 months of 10% or less, and ongoing moderate/severe pain and disability were defined as an NDI score at 6 months of 30% or greater. In addition, a small sample of physical therapists completed an anonymous survey on the clinical acceptability and usability of the tool. Results The positive predictive value of ongoing moderate/severe pain and disability was 90.9% in the validation cohort, and the positive predictive value of full recovery was 80.0%. Surveyed physical therapists reported that the whiplash CPR was simple, understandable, would be easy to use, and was an acceptable prognostic tool. External validation of the whiplash CPR confirmed the reproducibility and accuracy of this dual-pathway tool for individuals with acute whiplash-associated disorder. Further research is needed to assess prospective validation, the impact of inclusion on practice, and to examine the efficacy of linking treatment

At our hospital the current model of care for children with moderate-severe CF is focused on intensive inpatient intervention, regular outpatient clinic review and specialist outreach care as required. An alternative model providing more regular physiotherapy and dietetic outreach support, in addition to these specialist services, may be more effective. 16 children (4 male; 12 female; mean age 10.9±2.93; range 4-15 years) who required >40days of IV antibiotics in the 12-months pre-intervention were enrolled. Physiotherapy included weekly-supervised exercise sessions, alongside regular review of home physiotherapy regimens. Dietetic management included 1-2 monthly monitoring of growth, appetite, intake and absorption, and nutrition education sessions. There was a 23% reduction in inpatient IV antibiotic requirement and 20% reduction in home IV antibiotic requirement during the intervention year. Cost-benefit analyses showed savings of £113,570. VO(2Peak) increased by 4.9 ml·kg·min(-1) (95%CI 1.01 to 8.71; p=0.02), and 10 m-MSWT distance and increment achieved increased by 229 m (95%CI 109 to 350; pchildren with moderate-severe CF.

After the GINA 2006 publication, asthma therapy is based on control of symptoms. However there are suggestions of monitoring of airway inflammation. Aim of the study was to compare clinical criteria of asthma control with cellular markers of lower airway inflammation in induced sputum in a group of young asthmatics. To assess relationship between sputum eosinophilia, asthma severity and spirometry. A group of 154 young patients with chronic asthma (8-21 years) underwent sputum induction by inhalation of 4,5% saline solution. Sputum induction was effective in 121 patients (78%), and in this group control of clinical symptoms was assessed according to GINA 2006 criteria. Asthma was controlled in 82 subjects (67.8%) and uncontrolled in 39 (32.2%). Patients with controlled asthma had higher FEV1/FVC (79.8 +/- 7.1% vs 74.2 +/- 9.9%; p = 0.004) and MMEF (80.7 +/- 23.0% vs 65.3 +/- 21.8%; p 3%) was observed in 24.4% of patients with controlled asthma and in 61.5% with uncontrolled asthma (p astma than in patients with moderate-severe disease (3.1 +/- 5.7% vs 7.1% +/- 8.8; p = 0.006). Patients with high sputum eosinophil count had lower FEV1 (89.4 +/- 14.9% vs 94.9 +/- 13.9%; p = 0.047), FEV1/FVC (74.5 +/- 10.1% vs 79.2 +/- 9.3%; p = 0.01) and MMEF (68.7 +/- 23.3% vs 81.7 +/- 23.1%; p = 0.004). In this study of young asthmatics, control of asthma symptoms was observed in 67.8% of patients. However, cellular markers of lower airway inflammation were present in 1/4 of patients with controlled asthma and in 3/4 with uncontrolled disease. Sputum eosinophilia was related to asthma severity. FEV1/FVC and MMEF were more important that FEV1 for estimating control of asthma. Improvement of asthma control scoring is needed as well as availability of simple methods of inflammation monitoring.

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.

However, it is not clear why this is, since many different aspects of lifestyle and the environment have been linked with the onset of asthma. In Africa, asthma has typically been thought of as being very uncommon, and indeed in many African dialects there is no word for asthma or the symptoms, such as wheezing, that ...

Asthma is a complex disease influenced by multiple genetic and environmental factors. While Madeira has the highest prevalence of asthma in Portugal (14.6%), the effect of both genetic and environmental factors in this population has never been assessed. We categorized 98 asthma patients according to the Global Initiative for Asthma (GINA) guidelines, established their sensitization profile, and measured their forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) indexes. Selected single nucleotide polymorphisms (SNPs) were analysed as potential markers for asthma susceptibility and severity in the interleukin 4 (IL4), interleukin 13 (IL13), beta-2-adrenergic receptor (ADRB2), a disintegrin and metalloprotease 33 (ADAM33), gasdermin-like (GSDML) and the signal transducer and activator of transcription 6 (STAT6) genes comparatively to a population reference set. Although mites are the major source of allergic sensitization, no significant difference was found amongst asthma severity categories. IL4-590*CT/TT and IL4-RP2*253183/183183 were found to predict the risk (2-fold) and severity (3 to 4-fold) of asthma and were associated with a lower FEV1 index. ADRB2-c.16*AG is a risk factor (3.5-fold), while genotype GSDML-236*TT was protective (4-fold) for moderate-severe asthma. ADAM33-V4*C was associated to asthma and mild asthma by the transmission disequilibrium test (TDT). Finally, ADAM33-V4*CC and STAT6-21*TT were associated with higher sensitization (mean wheal size ≥10 mm) to house dust (1.4-fold) and storage mite (7.8-fold). In Madeira, IL4-590C/T, IL4-RP2 253/183, GSDML-236C/T and ADAM33-V4C/G SNPs are important risk factors for asthma susceptibility and severity, with implications for asthma healthcare management.

Caregivers who smoke and have children with asthma are an important group for intervention. Home-based interventions successfully reduce asthma morbidity, yet are costly. This study evaluated the financial return on investment (ROI) of the Parents of Asthmatics Quit Smoking (PAQS) program, a combined asthma education and smoking cessation intervention. Participants included caregivers (n = 224) that smoked, had a child with asthma, and were enrolled in a Medicaid managed care plan. Participants received nurse-delivered asthma education and smoking counseling in three home visits. Program implementation costs were estimated, and healthcare expenses were obtained from insurance claims data 12 months pre- and 12 months post intervention. ROI was calculated for all participants, children <6 years, children 6-18 years, and children with moderate/severe persistent asthma. Total program implementation cost was $34,481. After intervention, there was increased mean annual refills of beta-agonist (0.51 pre, 1.64 post; P < 0.001), and controller medications (0.65 pre, 2.44 post; P < 0.001). Reductions were found in mean annual emergency department visits (0.33 pre, 0.14 post; P < 0.001), hospitalizations (0.23 pre, 0.08 post; P < 0.001), and outpatient visits (2.33 pre, 1.45 post, P < 0.001). The program had negative ROI (-21.8%) for the entire sample. The ROI was positive (+106.9) for children <6 years, negative (-150.3) for children 6-18, and negligible for moderate/severe persistent asthma (+6.9%). PAQS was associated with increased medication use and decreased healthcare utilization. While the overall ROI for PAQS was negative, PAQS had a positive ROI for caregivers of young children with asthma. Copyright © 2012 Wiley Periodicals, Inc.

It is recognized that human rhinovirus (HRV) infection is an important factor in asthma exacerbations requiring hospitalization in children. However, previous studies have disagreed on the differential impact of various HRV species. We sought to assess the impact of HRV species on the severity of asthma exacerbations in children and adolescents. We also examined whether the effect of HRV species on severity was modified by age and gender. Virus strain was determined for 113 children with HRV detectable at the time of admission for asthma exacerbation. Patient characteristics were collected on admission and exacerbation severity was scored using several validated scales. HRV species by itself was not associated with moderate/severe vs. mild exacerbations. Boys with HRV-C infections were more likely (OR: 3.7, 95% CI: 1.2-13.4) to have a moderate/severe exacerbation than girls with HRV-C (p = 0.04 for interaction term). Higher odds were observed in younger boys (3 years old: OR: 9.1, 95% CI: 1.8-47.1 vs 5 years old: OR: 3.3, 95% CI: 0.9-11.8 vs 7 years old: OR: 1.2, 95% CI: 0.2-6.6). In contrast, children with HRV-C infection and sensitized to pollen during the pollen season were less likely to have moderate/severe exacerbations (p = 0.01 for the interaction term). Acute asthma exacerbations are more likely to be moderate/severe in boys under 5 years of age who had HRV-C infection on admission. The opposite was found in children with sensitization to pollen during pollen season.

Background: Optimal asthma control in pregnant women is very much essential for the good health of both mother and the fetus. Maternal and fetal complications occur due to poor control of asthma. There are concerns that management of bronchial asthma in pregnant women should be optimal by the health professionals. Objective: The aim of the study was to evaluate the knowledge and practices of young female doctors about the bronchial asthma management in pregnancy. Study Design: Randomized evidence based. Study Setting: Punjab Public Service Commission (PPSC) interviews for women medical officers and female doctors working in different medical units and chest unit of Mayo Hospital a tertiary care hospital affiliated with King Edward Medical University, Lahore. Materials and Methods: A questionnaire based survey of knowledge and practices of one hundred and one female doctors in the management of bronchial asthma was made. Amongst these, 32 doctors were FCPS 1 in medicine and gynecology. Remaining 69 doctors were in the pipeline and they have completed one year house job in different specialties. The case scenario was Asthma management approach during pregnancy in a stable patient of moderate severity. Inclusion Criteria 1. All those female doctors who have completed one year house job. 2. Female doctors working in gynecology, medicine, surgery and allied specialties. Results: Overall 14 (13.6%) doctors (5 (35.7%) PGs and 9 (64.3%) Non PGs) have the standard prescription of inhaled corticosteroids with long acting inhaled B2 agonists and montelukast as controller medication and short acting inhaled B2 agonist as needed as reliever medication according to the standard guidelines. Conclusion: The majority of young female doctors had the suboptimal knowledge and practice of asthma management in pregnancy. We suggest initiating the training programs to optimize their knowledge and practices. (author)

Childhood asthma is a complex disease. In this study, we aim to identify genes associated with childhood asthma through a multiomics "vertical" approach that integrates multiple analytical steps using linear and logistic regression models. In a case-control study of childhood asthma in Puerto Ricans (n = 1,127), we used adjusted linear or logistic regression models to evaluate associations between several analytical steps of omics data, including genome-wide (GW) genotype data, GW methylation, GW expression profiling, cytokine levels, asthma-intermediate phenotypes, and asthma status. At each point, only the top genes/single-nucleotide polymorphisms/probes/cytokines were carried forward for subsequent analysis. In step 1, asthma modified the gene expression-protein level association for 1,645 genes; pathway analysis showed an enrichment of these genes in the cytokine signaling system (n = 269 genes). In steps 2-3, expression levels of 40 genes were associated with intermediate phenotypes (asthma onset age, forced expiratory volume in 1 second, exacerbations, eosinophil counts, and skin test reactivity); of those, methylation of seven genes was also associated with asthma. Of these seven candidate genes, IL5RA was also significant in analytical steps 4-8. We then measured plasma IL-5 receptor α levels, which were associated with asthma age of onset and moderate-severe exacerbations. In addition, in silico database analysis showed that several of our identified IL5RA single-nucleotide polymorphisms are associated with transcription factors related to asthma and atopy. This approach integrates several analytical steps and is able to identify biologically relevant asthma-related genes, such as IL5RA. It differs from other methods that rely on complex statistical models with various assumptions.

Disturbances that alter the structure and function of forest ecosystems occur along a continuum of severity. In contrast to the extremes of the disturbance gradient (i.e., stand-replacing disturbance and small gap formation), moderate severity disturbances are poorly understood, even though they make up the majority of the gradient and their spatial extent (and likely overall importance to regional disturbance regimes) often exceeds that of more severe disturbances. Moderate severity disturbances originate from a variety of causes, such as fires, ice storms, or pest and pathogen outbreaks, and each of these could reshape structure and function in different ways. Observational data from a limited number of sites shows that moderate disturbance can increase ecosystem complexity, but the generality of this effect has not been tested across a broad range of disturbance types and severities. Here, we utilize data from a set of five case studies of experimental or natural moderate disturbance to assess the effects of different types and severities of disturbance on forest canopy structural complexity (CSC) and the relationship of canopy structure with ecosystem functioning. Using pre- and post-disturbance measures of CSC derived from aerial and terrestrial LiDAR, UAV imagery, and Landsat data we quantified changes in CSC following an experimental ice storm, a low-severity surface fire, Beech Bark Disease and Hemlock Wooly Adelgid outbreaks, and experimental accelerated succession. Our initial findings indicate that different disturbance types have highly variable effects on CSC, and also that progressive increases in disturbance severity alter CSC differently among disturbance types. Differential effects of variable disturbance types on CSC has implications for the carbon cycle, as forest structure is strongly linked with both growth-limiting resource (e.g., nutrients and light) acquisition and net primary productivity. Understanding how different types and severities of

To determine if the type of continuous positive airway pressure (CPAP) mask interface influences CPAP treatment efficacy, adherence, side effects, comfort and sleep quality in patients with moderate-severe obstructive sleep apnea (OSA). This took place in a hospital-based tertiary sleep disorders unit. It is a prospective, randomized, crossover trial comparing three CPAP interfaces: nasal mask (NM), nasal mask plus chinstrap (NM-CS) and oronasal mask (ONM) each tried in random order, for 4 weeks. After each 4-week period, patient outcomes were assessed. Participants had a new diagnosis of obstructive sleep apneas. Forty-eight patients with moderate-severe OSA (32 males, mean ± standard deviation apnea-hypopnea index (AHI) 55.6 ± 21.1 events/h, age 54.9 ± 13.1 years, body mass index 35.8 ± 7.2 kg/m 2 ) were randomized. Thirty-five participants completed the full study, with complete data available for 34 patients. There was no statistically significant difference in CPAP adherence; however, residual AHI was higher with ONM than NM and NM-CS (residual AHI 7.1 ± 7.7, 4.0 ± 3.1, 4.2 ± 3.7 events/h respectively, main effect P = .001). Patient satisfaction and quality of sleep were higher with the NM and NM-CS than the ONM. Fewer leak and mask fit problems were reported with NM (all chi-square P CPAP adherence did not differ between the three different mask interfaces but the residual AHI was lower with NM than ONM and patients reported greater mask comfort, better sleep, and overall preference for a NM. A nasal mask with or without chinstrap should be the first choice for patients with OSA referred for CPAP treatment.

Aims Although we previously demonstrated abdominal paracentesis drainage (APD) preceding percutaneous catheter drainage (PCD) as the central step for treating patients with moderately severe (MSAP) or severe acute pancreatitis (SAP), the predictors leading to PCD after APD have not been studied. Methods Consecutive patients with MSAP or SAP were recruited between June 2011 and June 2013. As a step-up approach, all patients initially received medical management, later underwent ultrasound-guided APD before PCD, if necessary, followed by endoscopic necrosectomy through the path formed by PCD. APD primarily targeted fluid in the abdominal or pelvic cavities, whereas PCD aimed at (peri)pancreatic fluid. Results Of the 92 enrolled patients, 40 were managed with APD alone and 52 received PCD after APD (14 required necrosectomy after initial PCD). The overall mortality was 6.5%. Univariate analysis showed that among the 20 selected parameters, 13 factors significantly affected PCD intervention after APD. Multivariate analysis revealed that infected (peri)pancreatic collections (P = -0.001), maximum extent of necrosis of more than 30% of the pancreas (P = -0.024), size of the largest necrotic peri(pancreatic) collection (P = -0.007), and reduction of (peri)pancreatic fluid collections by collections, a largest necrotic peri(pancreatic) collection of more than 100 ml, and reduction of (peri)pancreatic fluid collections by <50% after APD could effectively predict the need for PCD in the early course of the disease.

Acne patients experience not only a medical disease but also an aesthetic condition, and this latter complication greatly motivates patients to seek out the best treatment regimen to hasten improvement in their appearance. The available clinical procedures for acne treatment include salicylic acid 30% peel and pneumatic broadband light (PBBL). The objective of this study was to compare the efficacy of salicylic acid 30% peel and PBBL treatments in patients with mild to moderately severe facial acne vulgaris. Twelve patients were recruited for a 12-week prospective, single-blind, randomized, split-face study. Patients were treated with a salicylic acid 30% peel on one side of the face and PBBL treatment was administered on the opposite side of the face for 6 consecutive weeks without other acne treatments. At every visit, treatment evaluations were performed using a modified Global Acne Grading Score (mGAGS), acne quality of life (QOL) questionnaire, Wong-Baker FACES Pain Rating Scale (WBPRS) assessments, and clinical photography. Improvement in acne symptoms was observed for both treatment procedures without significant differences and with minimal side effects. Salicylic acid 30% peel and PBBL were well tolerated in our study, and both clinical procedures were efficacious and well-tolerated by the patients.

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.

Chronic inflammation in the lung has long been linked to the pathogenesis of asthma. Central to this airway inflammation is a T-cell response to allergens, with Th2 cytokines driving the differentiation, survival and function of the major inflammatory cells involved in the allergic cascade. PI3Kδ (phosphoinositide 3-kinase δ) is a lipid kinase, expressed predominantly in leucocytes, where it plays a critical role in immune receptor signalling. A selective PI3Kδ inhibitor is predicted to block T-cell activation in the lung, reducing the production of pro-inflammatory Th2 cytokines. PI3Kδ is also involved in B-cell and mast cell activation. Therefore the inhibition of PI3Kδ should dampen down the inflammatory cascade involved in the asthmatic response through a wide breadth of pharmacology. Current anti-inflammatory therapies, which are based on corticosteroids, are effective in controlling inflammation in mild asthmatics, but moderate/severe asthmatic patients remain poorly controlled, experiencing recurrent exacerbations. Corticosteroids have no effect on mast cell degranulation and do not act directly on B-cells, so, overall, a PI3Kδ inhibitor has the potential to deliver improvements in onset of action, efficacy and reduced exacerbations in moderate/severe asthmatics. Additionally, PI3Kδ inhibition is expected to block effects of Th17 cells, which are increasingly implicated in steroid-insensitive asthma.

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.

Acute asthma is one of the most common medical emergencies in children. Appropriate assessment/treatment and early identification of factors that predict hospitalization are critical for the effective utilization of emergency services. To identify risk factors that predict hospitalization and to compare the concordance of the Modified Pulmonary Index Score (MPIS) with the Global Initiative for Asthma (GINA) guideline criteria in terms of attack severity. The study population was composed of children aged 5-18 years who presented to the Emergency Departments (ED) of the tertiary reference centers of the country within a period of 3 months. Patients were evaluated at the initial presentation and the 1(st) and 4(th) hours. Of the 304 patients (median age: 8.0 years [interquartile range: 6.5-9.7]), 51.3% and 19.4% required oral corticosteroids (OCS) and hospitalization, respectively. Attack severity and MPIS were found as predicting factors for hospitalization, but none of the demographic characteristics collected predicted OCS use or hospitalization. Hospitalization status at the 1(st) hour with moderate/severe attack severity showed a sensitivity of 44.1%, specificity of 82.9%, positive predictive value of 38.2%, and negative predictive value of 86.0%; for MPIS ≥ 5, these values were 42.4%, 85.3%, 41.0%, and 86.0%, respectively. Concordance in prediction of hospitalization between the MPIS and the GINA guideline was found to be moderate at the 1(st) hour (κ = 0.577). Attack severity is a predictive factor for hospitalization in children with acute asthma. Determining attack severity with MPIS and a cut-off value ≥ 5 at the 1(st) hour may help physicians in EDs. Having fewer variables and the ability to calculate a numeric value with MPIS makes it an easy and useful tool in clinical practice. Copyright © 2013 Elsevier Inc. All rights reserved.

Many individuals who sustain moderate-severe traumatic brain injuries (TBI) are poor at recognizing emotional expressions, with a greater impairment in recognizing negative (e.g., fear, disgust, sadness, and anger) than positive emotions (e.g., happiness and surprise). It has been questioned whether this "valence effect" might be an artifact of the wide use of static facial emotion stimuli (usually full-blown expressions) which differ in difficulty rather than a real consequence of brain impairment. This study aimed to investigate the valence effect in TBI, while examining emotion recognition across different intensities (low, medium, and high). Twenty-seven individuals with TBI and 28 matched control participants were tested on the Emotion Recognition Task (ERT). The TBI group was more impaired in overall emotion recognition, and less accurate recognizing negative emotions. However, examining the performance across the different intensities indicated that this difference was driven by some emotions (e.g., happiness) being much easier to recognize than others (e.g., fear and surprise). Our findings indicate that individuals with TBI have an overall deficit in facial emotion recognition, and that both people with TBI and control participants found some emotions more difficult than others. These results suggest that conventional measures of facial affect recognition that do not examine variance in the difficulty of emotions may produce erroneous conclusions about differential impairment. They also cast doubt on the notion that dissociable neural pathways underlie the recognition of positive and negative emotions, which are differentially affected by TBI and potentially other neurological or psychiatric disorders.

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.

The objective of the present work was to search for the tissue and cellular markers of remodeling of bronchial mucosa in the patients with different clinical forms of bronchial asthma (BA). The use of up-to-date morphometric techniques has demonstrated that mild and moderately severe forms of bronchial asthma are accompanied by the development of Th2-immune response associated with increased production of interleukin-4 and marked degranulation of eosinophilic granulocytes resulting in desquamation of epithelium and goblet cell hyperplasia. The severe BA phenotype of "chronic asthma with fixed obstruction" is associated with the development of non-atopic inflammation in the bronchial mucous membrane that manifests itself as the increased concentration of interleukin-8 in bronchial mucosa and its neutrophilic infiltration leading to the development of pronounced subepithelial fibrosis, thickening of the basal membrane, and atrophy of epithelium. Specific structural changes in bronchial mucosa of the patients presenting with BA underlie functional disturbances that cause severe bronchial obstructive syndrome.

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. This article reviews the current biologics available and under development and how their use has affected asthma and which subpopulations appear to benefit the greatest.

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.
The goal of asthma management is to achieve disease control. Poorly controlled asthma is associated with an increased number of days lost from school, exacerbations and days in hospital. Furthermore, children with uncontrolled asthma have more frequent contacts with the health-care system. Recent...... studies have added new information about the effects of poorly controlled asthma on a range of important, but less studied outcomes, including risk of obesity, daily physical activity, cardiovascular fitness, stress, concentration and focused attention, learning disabilities and risk of depression. From...... these studies it seems that poor asthma control may have a greater impact on the child than previously thought. This may have important long-term consequences for the child such as an increased risk of life-style associated diseases and poorer school performance. The level of control seems to be the most...

Full Text Available By dopplerechocardiography method there was studied functional state of cardiac ventricles and character of hemodynamic disorders in 48 patients aged 5-17 years in attack period of moderately-severe and severe bronchial asthma. Group of comparison included 40 healthy peers. Disorders of central and peripheral hemodynamic in attack period of bronchial asthma in children were accompanied both by systolic and diastolic dysfunction of the left and right heart ventricles, herewith right ventricle was functioning in the mode of hyperdynamic, and left one – in the mode of hypodynamic. Combined systolic-diastolic variant of dysfunction both of right and left ventricles was developing in 58,3% of patients with moderately-severe and in 91,6% of patients with severe bronchial asthma. In the attack period of bronchial asthma in children equal directionality of systolic and diastolic dysfunction of heart ventricles was developing; this was characterized by synchronization of their function. Assessment of functional interaction of the ventricles under conditions of severe asthma attack showed direct and high (r=0,67 correlative interaction between finding of Tei index of the left and right ventricles, which characterize their systolic function; this, under conditions of increased hemodynamic pre-loading testified to compensatory increase of systolic interaction of ventricles. Direct and high (r=0,69 correlative interaction between time indices of isovolumic relaxation of the left and right ventricles, characterizing their diastolic function, testified to compensatory increase of diastolic interaction of ventricles under conditions of increase of hemodynamic post-loading. Imbalance of central and peripheral link of hemodynamic in attack period of bronchial asthma in children testified to development of cardiac insufficiency, which was compensated predominantly at the expense of increase of heart contractions rate.

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)

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.

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.

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.

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

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.

Omalizumab is a subcutaneously administrated monoclonal anti-IgE antibody indicated in adults, adolescents and children 6 years of age and older with moderate to severe allergic asthma uncontrolled by conventional pharmacological treatments and sensitization to at least one perennial allergen. Area covered: This drug evaluation summarizes published data on pharmacokinetic and pharmacodynamic properties of omalizumab, on clinical efficacy and safety, including real-world evidence, and provides a medico-economic evaluation of the drug. Expert opinion: Omalizumab represents an efficient therapeutic option for the management of patients with uncontrolled moderate/severe allergic asthma. It provides a significant reduction in the asthma exacerbation rate with a steroid-sparing effect, an improvement in quality of life in adults and adolescents, despite a lack of evidence about its efficacy specifically in severe allergic asthma. Clinical trials have demonstrated its efficacy in the pediatric population but further real-life evidence is expected to better characterize long-term effects in this population. There is still some debate about the optimal treatment duration but, to date, it is recommended not to stop the treatment as cessation has resulted in symptom recurrence. Omalizumab is an expensive treatment, but a key therapeutic option when used for uncontrolled severe allergic asthma.

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.

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

Bias in estimating the cross-sectional smoking, alcohol, obesity and diabetes associations with moderate-severe periodontitis in the Atherosclerosis Risk in Communities study: comparison of full versus partial-mouth estimates.
Akinkugbe, Aderonke A; Saraiya, Veeral M; Preisser, John S; Offenbacher, Steven; Beck, James D
To assess whether partial-mouth protocols (PRPs) result in biased estimates of the associations between smoking, alcohol, obesity and diabetes with periodontitis. Using a sample (n = 6129) of the 1996-1998 Atherosclerosis Risk in Communities study, we used measures of probing pocket depth and clinical attachment level to identify moderate-severe periodontitis. Adjusting for confounders, unconditional binary logistic regression estimated prevalence odds ratios (POR) and 95% confidence limits. Specifically, we compared POR for smoking, alcohol, obesity and diabetes with periodontitis derived from full-mouth to those derived from 4-PRPs (Ramfjörd, National Health and Nutrition Examination survey-III, modified-NHANES-IV and 42-site-Random-site selection-method). Finally, we conducted a simple sensitivity analysis of periodontitis misclassification by changing the case definition threshold for each PRP. In comparison to full-mouth PORs, PRP PORs were biased in terms of magnitude and direction. Holding the full-mouth case definition at moderate-severe periodontitis and setting it at mild-moderate-severe for the PRPs did not consistently produce POR estimates that were either biased towards or away from the null in comparison to full-mouth estimates. Partial-mouth protocols result in misclassification of periodontitis and may bias epidemiologic measures of association. The magnitude and direction of this bias depends on choice of PRP and case definition threshold used. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

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.

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.

Full Text Available Bronchial asthma is a prevalent chronic allergic disease of lungs at early ages. A priority task in allergology is to search biological markers related to uncontrolled atopic bronchial asthma. Cytokines fulfill their distinct function in pathogenesis of atopic bronchial asthma, participating at the initiation, development and persistence of allergic inflammation in airways, causing different variations of clinical course of the disease (with respect to its acuteness, severity, frequency of exacerbations. The present work has studied indices of cellular and humoral links of immunity, as well as levels of some pro and anti-inflammatory cytokines in peripheral blood serum (IL-4, IL-10, IL-2 and TNFα, aiming to determine potential markers of uncontrolled atopic bronchial asthma in children. A group of Caucasian (European children was involved into the research: Cohort 1, moderate atopic bronchial asthma with controlled course during the last 3 months (n = 59; Cohort 2, severe/moderate-severe atopic bronchial asthma with uncontrolled course of the disease within last 3 months (n = 51, Cohort 3 – control, practically healthy children without signs of atopy (n = 33. All the children included in the group with atopic bronchial asthma underwent regular mono/combined basic therapy at high/ intermediate therapeutic doses. We performed a comparative analysis of cell population indices reflecting certain cellular immunity links, and determined significantly lower levels of CD3+ lymphocytes, as well as decrease in relative and absolute contents of CD4+ and CD8+ cells in the cohort with uncontrolled course of atopic bronchial asthma, as compared with controlled-course cohort. When evaluating concentrations of cytokines in peripheral blood serum of the patients with controlled and uncontrolled atopic bronchial asthma, we revealed significantly higher

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.
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.

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.

Asthma is characterized by a chronic inflammatory reaction in the airways. Roughly, asthma can be subdivided into atopic asthma involving elevated levels of serum IgE and a less familiar form, non-atopic asthma. Non-atopic asthma is an increasing problem in the developed world. The mechanisms
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

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.

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...

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.

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.
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.

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.
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.
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.

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.

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.

The aim was to develop and implement an evidence based guideline for the treatment of acute asthma using a metered dose inhaler and spacer combination. Children admitted to Cork University Hospital Paediatric Department with acute asthma were identified during two identical 2 month seasonal periods before (2005) and after (2006) implementation of the new guidelines in September 2006. Pre-intervention and post-intervention audits by case note review were performed to determine the impact of and compliance with this evidence-based guideline emphasising patient assessment, spacer delivered bronchodilator and specific discharge criteria. Patients had similar characteristics during the two study periods. There was a raised threshold for admission after guideline implementation with 11\\/52 patients having mild exacerbations in 2006, compared to 21\\/36 in 2005. Duration of admission was less in the post-implementation group for equivalent exacerbation severity e.g. for moderate severity; 28 hours in 2005, 23 hours in 2006. Duration of bronchodilator therapy was shorter in 2006 and more likely to be given by spacer device earlier for equivalent levels of severity e.g. for moderate exacerbations, in 2006 the average length of salbutamol therapy was 18 hours with 12 hours by spacer device, in 2005 the average length of therapy was 25 hours with 3 hours by spacer. There was earlier initiation of oral corticosteroids; the average time to administration was 56 minutes in 2006 and 227 minutes in 2005. There was an improved documentation of asthma education in 2006 e.g. inhaler technique was reviewed in 37\\/52 in 2006, 21\\/35 in 2005 and better use of written action plans.

In asthma, socio-economic and health care factors may operate by a number of mechanisms to influence asthma morbidity and mortality. To determine the quality of medical care including the patient perception of the doctor-patient relationship, and the level of socio-economic disadvantage in patients admitted to hospital with acute severe asthma. One hundred and thirty-eight patients (15-50 years) admitted to hospital (general ward or intensive care unit) with acute asthma were prospectively assessed using a number of previously validated instruments. The initial subjects had severe asthma on admission (pH = 7.3 +/- 0.2, PaCO2 = 7.1 +/- 5.0 kPa, n = 90) but short hospital stay (3.7 +/- 2.6 days). Although having high morbidity (40% had hospital admission in the last year and 60% had moderate/severe interference with sleep and/or ability to exercise), they had indicators of good ongoing medical care (96% had a regular GP, 80% were prescribed inhaled steroids, 84% had a peak flow meter, GP measured peak flow routinely in 80%, 52% had a written crisis plan and 44% had a supply of steroids at home). However, they were severely economically disadvantaged (53% had experienced financial difficulties in the last year, and for 35% of households the only income was a social security benefit). In the last year 39% had delayed or put off GP visit because of cost. Management of the index attack was compromised by concern about medical costs in 16% and time off work in 20%. Patients admitted to hospital with acute asthma have evidence of good quality on-going medical care, but are economically disadvantaged. If issues such as financial barriers to health care are not acknowledged and addressed, the health care services for asthmatics will not be effectively utilised and the current reductions in morbidity and mortality may not be maintained.

Acute asthma attack is a frequent condition in children. It is one of the most common reasons for emergency department (ED) visit and hospitalization. Appropriate care is fundamental, considering both the high prevalence of asthma in children, and its life-threatening risks. Italian Society of Pediatrics recently issued a guideline on the management of acute asthma attack in children over age 2, in ambulatory and emergency department settings. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was adopted. A literature search was performed using the Cochrane Library and Medline/PubMed databases, retrieving studies in English or Italian and including children over age 2 year. Inhaled ß 2 agonists are the first line drugs for acute asthma attack in children. Ipratropium bromide should be added in moderate/severe attacks. Early use of systemic steroids is associated with reduced risk of ED visits and hospitalization. High doses of inhaled steroids should not replace systemic steroids. Aminophylline use should be avoided in mild/moderate attacks. Weak evidence supports its use in life-threatening attacks. Epinephrine should not be used in the treatment of acute asthma for its lower cost / benefit ratio, compared to β 2 agonists. Intravenous magnesium solphate could be used in children with severe attacks and/or forced expiratory volume1 (FEV1) lower than 60% predicted, unresponsive to initial inhaled therapy. Heliox could be administered in life-threatening attacks. Leukotriene receptor antagonists are not recommended. This Guideline is expected to be a useful resource in managing acute asthma attacks in children over age 2.

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

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.

Allergic rhinitis and asthma represent global problems of public health affecting all age groups; asthma and allergic rhinitis frequently coexist in the same patients. In Latin American prevalence of allergic rhinitis, although variable, is very high. Allergic rhinitis and its Impact on Asthma (ARIA) started during a workshop of the World Health Organization performed in 1999 and was published in 2001. ARIA proposed a new classification of allergic rhinitis in intermittent or persistent and mild or moderate-severe. This approach of classification reflects more nearly the impact of allergic rhinitis in patients. In its review of 2010 ARIA developed guidelines for diagnosis and treatment of allergic rhinitis and of clinical practices for management of comorbidities of allergic rhinitis and asthma based on GRADE (Grading of Recommendations, Development and Evaluation). ARIA has been spread and implemented in more than 50 countries. In Latin American an intense activity has been developed to spread these recommendations in almost all the countries of the region and it is important to record the obtained goals in the diffusion and implementation of ARIA, as well as to identify the unsatisfied needs from the clinical, research and implementation points of view. Final objective is to reinforce the priority that allergy and asthma should have, especially in children, in the programs of public health, as they have been prioritized in European Union in 2011.

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.

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.

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...

Allergic rhinitis is the commonest chronic respiratory disorder in children and young adults having an important impact for those suffering this condition, as well as for the public health. Allergic rhinitis is frequently associated to other co-morbidities, particularly asthma and conjunctivitis but, also, sinusitis and otitis media. Most of patients suffering rhinitis are cared by GPs and pediatricians and there are evidences that allergic rhinitis is undertreated, particularly the moderate/severe persistent forms. Clinical guidelines have become an important tool providing recommendations for diagnosis and treatment of different medical conditions. They help the process of decision making for GPs and pediatricians, and many of them, contain an update on basic science and epidemiology. In respiratory medicine, guidelines on asthma and rhinitis are available; however, they do not look at the patients globally and focus the disorder on an organ-specific basis without recommendations on co-morbidities. ARIA, Allergic rhinitis and its impact on asthma, has not been developed only to update specialists in allergy/immunology, otorhinolaryngology and neumology on rhinitis and its comorbidities but, also, to provide recommendations for non-specialists. A new classification and severity of allergic rhinitis is proposed replacing the classic perennial and seasonal forms for persistent and intermittent, mild to moderate/severe. ARIA is an initiative in collaboration with the World Health Organization and the master document has been endorsed by many national and international scientific societies and organizations. ARIA is an evidence-based document also stressing on pediatric aspects and providing recommendations for low-income countries.

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...

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.

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.
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.

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.

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.

BACKGROUND: Long term administration of oral corticosteroids in patients with asthma may be associated with serious side effects. Non-steroidal anti-inflammatory drugs, including gold salts, have been shown to reduce the need for systemic corticosteroid treatment in uncontrolled studies. The effect of oral gold (auranofin) on asthma symptoms, lung function, and the need for oral prednisone treatment was investigated. METHODS: A 26 week randomised, double blind, placebo controlled, parallel group trial of auranofin was performed in 32 patients with moderately severe chronic asthma who required an oral corticosteroid dose of at least 5 mg prednisone a day (or equivalent) or 2.5 mg/day prednisone plus more than 800 micrograms/day inhaled corticosteroids. Auranofin was given orally in a dose of 3 mg twice daily. Asthma symptoms, lung function, and adverse effects were assessed at regular intervals. After 12 weeks of treatment prednisone dosage was tapered down by 2.5 mg every two weeks if the patient was clinically stable. Asthma exacerbations were treated with short courses of high doses of oral steroids. RESULTS: Twenty eight of the 32 patients, 13 in the placebo group and 15 in the auranofin group, completed the study. The total corticosteroid reduction achieved after 26 weeks of treatment was significantly greater (4 mg) in the auranofin group than in the placebo group (0.3 mg). The number of exacerbations requiring an increase of steroids was greater in the placebo group (2.1) than in the active group (0.9). A significant increase in FEV1 of 6.4% predicted occurred in the auranofin group during the study and there was a reduction of asthma symptoms such as wheezing and cough. There was no difference between the groups in peak flow measurements or in the number of asthma attacks. The incidence of side effects of auranofin was low, but exacerbations of constitutional eczema were noticeable. CONCLUSION: Auranofin provides an effective adjunct to treatment for steroid

Assessment of asthma control in children by physicians, patients and their parents was compared, assuming parents may underestimate symptoms in asthmatic children and exploring whether physicians tend to agree with them. Asthma control perception was assessed in 4- to 11-year-old asthmatic children and their parents, using C-ACT, during 2011-2012. Pediatric pulmonologists used GINA guidelines for their assessment; pediatricians, not having spirometry, used the information given in addition to physical examination. The C-ACT scores given by the children and their parents were further analyzed separately, and compared with their physicians' assessment. Statistical methods, which also measured possible influence of different variables, included kappa, Chi-square, linear-by-linear association, McNemar test and logistic regression. The study comprised 354 parents and children aged 4-11 years with moderate-severe asthma; 129 (36.4%) were treated by 23 pediatricians; 225 (63.6%) by 11 pediatric pulmonologists. The C-ACT was generally found valid in assessing asthma control (P children the asthma was uncontrolled. Nevertheless, of the 229 children who indicated their asthma was uncontrolled, 124 (54.1%) of their parents (κ 0.245; CI 0.15, 0.34) and 96 (41.9%) of their physicians believed it to be controlled (κ 0.331; 0.24, 0.43). Comparing the physician-child discordance vis-à-vis the parents, the significant difference was when 96/229 children (41.9%) and 34/126 parents (27.0%) indicated the asthma was uncontrolled while the physician determined it controlled (OR 1.95; 1.19, 3.24). There were no significant differences between pediatric pulmonologists and pediatricians. In addition to increasing awareness of parents to symptoms in their asthmatic children, physicians should question the child appropriately, as well as using the children's responses to C-ACT as an information source for properly assessing asthma control. © 2013 Wiley Periodicals, Inc.

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.

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...

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
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.
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.
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.

Full Text Available The increasing prevalence of asthma (A and diabetes mellitus type 2 (DM2T necessitates administration of the adequate antiasthmatic long-term basic therapy with consideration of comorbid states. The purpose consisted in revealing the therapeutic potential of Tiotropium bromide (TB and L-arginine (Tivortine in patients having uncontrolled moderately severe asthma in combination with DM2T (A+DM2T. Forty seven A+DM2T patients underwent an in-depth study before and after their treatment. They were divided into 2 groups: treatment (group 1, n=28 and comparison (group 2, n=19. Both groups received the standard 2-component therapy: budesonide/formoterol fumarate dihydrate – 160/4.5µg by 2 breaths twice a day and metformin at a dose of 500 mg twice a day. The complex of their basic therapy for group 1 additionally included TB (18 µg a day and arginine hydrochloride preparation (Tivortine® aspartate, Yuriya-Farm orally by 15 ml twice a day during 3 months (90 days. The patients were followed up 3 months and one year later. Their general condition demonstrated positive dynamics in both groups, the number of exacerbations in group 1 reducing by a factor of 4. The complex use of L-arginine and TB preparations against a background of the basic therapy in A+DM2T patients produced a better control over the disease, a more rapid elimination of obstruction manifestations, achievement and prolongation of the clinical spirographic remission, an improvement of the quality of life, correction of disturbances in haemocoagulation, fibrinolysis and the functional state of endothelium.

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

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.

To study the intensity of inflammatory infiltrate and production of interleukin-1β (ll-1β), tumor necrosis factor-β (TNF-β), fibroblast growth factor-2 (FGF-2), glutathione peroxidase (GPX), and osteocalcin in response to in-office tooth bleaching in rats. Twenty male Wistar rats were randomized into four groups (n=5) according to the received treatment (tooth bleaching or no treatment - control) and the period of euthanasia after treatment (24 h or 10 days). We performed tooth bleaching using a 38% hydrogen peroxide gel on maxillary and mandibular incisors. After euthanasia, incisors (20 per group) were processed for histological analysis, immunohistochemistry staining of ll-1β, TNF-β, FGF-2 and GPX and osteocalcin by immunofluorescence. We analyzed data using the Mann-Whitney and Kruskal-Wallis/Dunn tests (p<0.05). The bleached groups presented statistically significant differences regarding the pulp inflammation stage compared with the control groups. Bleached teeth showed moderate/severe inflammatory infiltrate and control groups presented absent inflammatory cells or a negligible number of mononuclear cells (p<0.001) at two times (24 h and 10 days). There was strong staining for ll-1β, TNF-β, and GPX in bleached groups at 24 h and strong staining for ll-1β, TNF-β, GPX and FGF-2 at 10 days. After 10 days of tooth bleaching, the bleached group showed a statistically superior amount of osteocalcin than the other groups (p<0.01). Tooth bleaching with 38% hydrogen peroxide causes severe pulp inflammation, but characteristics of tissue repair after 10 days.

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 availabi...

Severe asthma is defined by persistent symptoms and frequent exacerbations despite intensive asthma therapy. The prevalence is estimated to be 5-10% of all asthmatics. Severe asthma is responsible for a major burden of illness including low quality of life and a disproportionate use of health......-care resources. The clinical assessment of severe asthma must include verification of the correct diagnosis, adherence to medication, excluding differential diagnosis and identification and treatment of aggravating co-morbidities and trigger factors....
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.

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.

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.

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.

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.

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

Objective: The aim of the study was to evaluate determinants for the prognosis of asthma in a population-based cohort of young adults. Design: The study was a nine-year clinical follow up of 239 asthmatic subjects from an enriched population-based sample of 1,191 young adults, aged 20-44 years, who...... participated in an interviewer-administered questionnaire and clinical examination at baseline in 2003-2006. From the interview, an asthma score was generated as the simple sum of affirmative answers to five main asthma-like symptoms in order to analyse symptoms of asthma as a continuum. The clinical...... examination comprised spirometry, bronchial challenge or bronchodilation, and skin prick test. Results: Among the 239 individuals with asthma at baseline 164 (69%) had persistent asthma at follow up, while 68 (28%) achieved remission of asthma and seven (3%) were diagnosed with COPD solely. Determinants...

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.

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 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.

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.
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.

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.

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.

Conclusion: A high index of suspicion is warranted for the overlap of OSA and asthma, particularly in the presence of obesity, GERD, and in patients with severe asthma. Individualized therapy addressing these moderating factors is warranted for optimal health outcomes. Recognition and treatment of OSA in asthmatics is an important element in improving asthma control.

Abstract The incidence, prevalence, and mortality of asthma have increased in children over the past three to four decades, although there has been some decline in the most recent decade. These trends are particularly marked and of greatest concern in preschool children. Internationally, there are huge variations among countries and continents, as demonstrated by the International Study of Asthma and Allergies in Childhood. In general, asthma rates were highest in English-speaking countries (...

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.

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...

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.

To focus on both positive and negative aspects of the interaction between asthmatic patients and the social networks, and to highlight the need of a psychological approach in some individuals to integrate pharmacological treatment is the purpose of review. There is evidence that in some asthmatic patients, the excessive use of social networks can induce depression and stress triggering bronchial obstruction, whereas in others their rational use can induce beneficial effects in terms of asthma management. The increasing asthma prevalence in developed countries seen at the end of last century has raised concern for the considerable burden of this disease on society as well as individuals. Bronchial asthma is a disease in which psychological implications play a role in increasing or in reducing the severity of bronchial obstruction. Internet and, in particular, social media are increasingly a part of daily life of both young and adult people, thus allowing virtual relationships with peers sharing similar interests and goals. Although social network users often disclose more about themselves online than they do in person, there might be a risk for adolescents and for sensitive individuals, who can be negatively influenced by an incorrect use. However, although some studies show an increased risk of depression, other observations suggest beneficial effects of social networks by enhancing communication, social connection and self-esteem.

To perform a cost-utility analysis on asthmatic patients on beclomethasone/formoterol fixed combination in Primary Health Care. Material and methods Non-probability sampling was used to select a group of asthmatic patients with moderate/severe persistent severity (GEMA 2009), treated with beclomethasone/formoterol fixed combination, over 18 years, had given their informed consent. The study observation period was 6 months. The variables studied were: age, sex, duration of disease, health resources used, analysis of health related quality of life by EQ-5D and SF-36, and the specific Asthma Quality of Life Questionnaire. For the qualitative variables, the frequency and percentages were calculated, and for the quantitative variables, the mean, SD and 95% CI. Chi-square, Student t-test and ANOVA were used for statistical inference. Comparisons were made with a statistical significance of 0.05. Of the 64 patients that completed the study, 59.4% were female. The mean age was 49 years, and mean disease duration was 93 months. For asthma control, 53% of patients had a prescription pattern of one/12h. All health related quality of life scales were modified with respect to the baseline and the differences were statistically significant. Our patients had a better health related quality of life than Spanish asthma cohort. The incremental cost utility beclomethasone/formoterol versus usual treatment option was € 6,256/QALY.

Observational studies report inverse associations between the use of feather upper bedding (pillow and/or quilt) and asthma symptoms but there is no randomised controlled trial (RCT) evidence assessing the role of feather upper bedding as a secondary prevention measure. To determine whether, among children not using feather upper bedding, a new feather pillow and feather quilt reduces asthma severity among house dust mite (HDM) sensitised children with asthma over a 1-year period compared with standard dust mite avoidance advice, and giving children a new mite-occlusive mattress cover. RCT. The Calvary Hospital in the Australian Capital Territory and the Children's Hospital at Westmead, Sydney, New South Wales. 197 children with HDM sensitisation and moderate to severe asthma. Intervention New upper bedding duck feather pillow and quilt and a mite-occlusive mattress cover (feather) versus standard care and a mite-occlusive mattress cover (standard). The proportion of children reporting four or more episodes of wheeze in the past year; an episode of speech-limiting wheeze; or one or more episodes of sleep disturbance caused by wheezing; and spirometry with challenge testing. Statistical analysis included multiple logistic and linear regression. No differences between groups were found for primary end points--frequent wheeze (OR 1.51, 95% CI 0.83 to 2.76, p=0.17), speech-limiting wheeze (OR 0.70, 95% CI 0.32 to 1.48, p=0.35), sleep disturbed because of wheezing (OR 1.17, 95% CI 0.64 to 2.13, p=0.61) or for any secondary end points. Secondary analyses indicated the intervention reduced the risk of sleep being disturbed because of wheezing and severe wheeze to a greater extent for children who slept supine. No differences in respiratory symptoms or lung function were observed 1 year after children with moderate-severe asthma and HDM sensitisation were given a mite-occlusive mattress cover and then received either feather upper bedding (pillow and quilt) or standard

BACKGROUND: Women are more often admitted to hospital for asthma than men. A study was undertaken to determine whether this is caused by gender differences in the prevalence or severity of the disease. METHODS: Admissions to hospital for asthma in 13,540 subjects were followed from 1977 to 1993....... RESULTS: At baseline 315 subjects (2.3%) reported asthma, 2.2% of women and 2.5% of men. During follow up 160 subjects were admitted to hospital for asthma. After controlling for self-reported asthma and smoking, women had a higher risk of being admitted to hospital than men (relative risk 1.7, 95...

In 2010, an estimated 8.2% of U.S. adults had current asthma, and among these persons, 49.1% had had an asthma attack during the past year (1). Workplace exposures can cause asthma in a previously healthy worker or can trigger asthma exacerbations in workers with current asthma* (2). To assess the industry- and occupation-specific prevalence of current asthma, asthma attacks, and asthma-related emergency department (ED) visits among working adults, CDC analyzed 2011-2016 National Health Interview Survey (NHIS) data for participants aged ≥18 years who, at the time of the survey, were employed at some time during the 12 months preceding the interview. During 2011-2016, 6.8% of adults (11 million) employed at any time in the past 12 months had current asthma; among those, 44.7% experienced an asthma attack, and 9.9% had an asthma-related ED visit in the previous year. Current asthma prevalence was highest among workers in the health care and social assistance industry (8.8%) and in health care support occupations (8.8%). The increased prevalence of current asthma, asthma attacks, and asthma-related ED visits in certain industries and occupations might indicate increased risks for these health outcomes associated with workplace exposures. These findings might assist health care and public health professionals in identifying workers in industries and occupations with a high prevalence of current asthma, asthma attacks, and asthma-related ED visits who should be evaluated for possible work-related asthma. Guidelines intended to promote effective management of work-related asthma are available (2,3).

Wheezing in infancy has been associated with subsequent asthma, but whether cough similarly influences asthma risk has been little studied. We sought to determine whether prolonged cough and cough without cold in the first year of life are associated with childhood asthma. Participants in the Infant Immune Study, a non-selected birth cohort, were surveyed 7 times in the first 9 months of life regarding the presence of wheeze and cough. Cough for more than 28 days was defined as prolonged. Parents were asked at 1 year if the child ever coughed without a cold. Asthma was defined as parental report of physician diagnosis of asthma, with symptoms or medication use between 2 and 9 years. Logistic regression was used to assess adjusted odds for asthma associated with cough characteristics. A total of 24% (97) of children experienced prolonged cough and 23% (95) cough without cold in the first 9 months, respectively. Prolonged cough was associated with increased risk of asthma relative to brief cough (OR 3.57, CI: 1.88, 6.76), with the risk being particularly high among children of asthmatic mothers. Cough without cold (OR 3.13, 95% CI: 1.76, 5.57) was also independently associated with risk of childhood asthma. Both relations persisted after adjustment for wheeze and total IgE at age 1. Prolonged cough in infancy and cough without cold are associated with childhood asthma, independent of infant wheeze. These findings suggest that characteristics of cough in infancy are early markers of asthma susceptibility, particularly among children with maternal asthma. © 2015 John Wiley & Sons Ltd.

The objective of the present study was to estimate the efficacy and safety of combination of anti-inflammatory treatment of bronchial asthma (BA) and therapy with erespal. A total of 57 children aged from 6 to 14 years were available for the observation. They presented with mild intermittent (n=27), mild persisting (n=20), and moderately severe (n=10) forms of the disease. The traditional treatment of all the patients was supplemented by daily intake of erespal syrup at a dose of 4 mg/kg b.w. from the first day after admission to the hospital. It is concluded based on the results of the study that the use of erespal reduces the duration of the disease and the time of recovery of bronchial patency; also, it accelerates the process of arterial blood saturation with oxygen.

Full Text Available Abstract Background In well-child care it is difficult to determine whether preschool children with asthma symptoms actually have or will develop asthma at school age. The PIAMA (Prevention and Incidence of Asthma and Mite Allergy Risk Score has been proposed as an instrument that predicts asthma at school age, using eight easy obtainable parameters, assessed at the time of first asthma symptoms at preschool age. The aim of this study is to present the rationale and design of a study 1 to externally validate and update the PIAMA Risk Score, 2 to develop an Asthma Risk Appraisal Tool to predict asthma at school age in (specific subgroups of preschool children with asthma symptoms and 3 to test implementation of the Asthma Risk Appraisal Tool in well-child care. Methods and design The study will be performed within the framework of Generation R, a prospective multi-ethnic cohort study. In total, consent for postnatal follow-up was obtained from 7893 children, born between 2002 and 2006. At preschool age the PIAMA Risk Score will be assessed and used to predict asthma at school age. Discrimination (C-index and calibration will be assessed for the external validation. We will study whether the predictive ability of the PIAMA Risk Score can be improved by removing or adding predictors (e.g. preterm birth. The (updated PIAMA Risk Score will be converted to the Asthma Risk Appraisal Tool- to predict asthma at school age in preschool children with asthma symptoms. Additionally, we will conduct a pilot study to test implementation of the Asthma Risk Appraisal Tool in well-child care. Discussion Application of the Asthma Risk Appraisal Tool in well-child care will help to distinguish preschool children at high- and low-risk of developing asthma at school age when asthma symptoms appear. This study will increase knowledge about the validity of the PIAMA risk score and might improve risk assessment of developing asthma at school age in (specific subgroups

Obesity and asthma are two chronic conditions that affect millions of people. Genetic and lifestyle factors such as diet, physical activity, and early exposure to micro-organisms are important factors that may contribute to the escalating prevalence of both conditions. The prevalence of asthma is higher in obese individuals. Recently, two major phenotypes of asthma with obesity have been described: one phenotype of early-onset asthma that is aggravated by obesity, and a second phenotype of later-onset asthma that predominantly affects women. Systemic inflammation and mechanical effect, both due to the expansion of the adipose tissue, have been proposed as the main reasons for the association between obesity and asthma. However, the mechanisms involved are not yet fully understood. Moreover, it has also been suggested that insulin resistance syndrome can have a role in the association between these conditions. The intestinal microbiota is an important factor in the development of the immune system, and can be considered a link between obesity and asthma. In the obese state, higher lipopolysaccharide (LPS) serum levels as a consequence of a microbiota dysbiosis have been found. In addition, changes in microbiota composition result in a modification of carbohydrate fermentation capacity, therefore modifying short chain fatty acid (SCFA) levels. The main objective of this review is to summarize the principal findings that link obesity and asthma.

Asthma is common and in many, particularly those with more severe disease, there remains a substantial unmet need. Success with biologics targeting eosinophilic inflammation underscore the value of treating inflammation in asthma beyond corticosteroids. Fevipiprant (QAW039) is an oral treatment for asthma. It competitively and reversibly antagonises the prostaglandin D2 receptor 2 (DP2) expressed on inflammatory and structural cells. Areas covered: We reviewed fevipiprant's mode of action and efficacy against other current and emerging pharmacological interventions for moderate-to-severe asthma. We undertook a literature review using the PubMed/Medline database, the U.S. National Library of Medicine's Clinical Trials website and from manufacturers' press releases with the search terms: 'QAW039', 'Fevipiprant', 'CRTH2 antagonists', 'DP2', 'DP1', 'monoclonal antibody', 'eosinophil' with 'asthma' plus the names of individual drugs. Three Phase 2 trials have been conducted and three Phase 3 trials (NCT02563067, NCT03052517, NCT02555683) are in progress. To date Fevipiprant's greatest success has been in targeting severe eosinophilic asthma. Expert opinion: Fevipiprant presents the possibility of a new orally active therapy for asthma. If successful in phase 3 trials it will have an enormous impact on the treatment paradigm for asthma and will potentially widen access for pre-biologic treatment to a larger population.

Successfully diagnosing concomitant asthma in people with cystic fibrosis (CF) is a challenging proposition, and the utility of conventional diagnostic criteria of asthma in CF populations remains uncertain. Nonetheless, the accurate identification of individuals with CF and asthma allows appropriate tailoring of therapy, and should reduce the unnecessary use of asthma medication in broader CF cohorts. In this review, we discuss the diagnostic challenge posed by asthma in CF, both in terms of clinical evaluation, and of interpretation of pulmonary function testing and non-invasive markers of airway inflammation. We also examine how the role of cross-sectional thoracic imaging in CF and asthma can assist in the diagnosis of asthma in these patients. Finally, we critically appraise the evidence base behind the use of asthma medications in CF populations, with a particular focus on the use of inhaled corticosteroids and bronchodilators. As shall be discussed, the gaps in the current literature make further high-quality research in this field imperative. © 2014 Wiley Periodicals, Inc.

Full Text Available Asthma in childhood is a heterogeneous disease with different phenotypes and variable clinical manifestations, which depend on the age, gender, genetic background, and environmental influences of the patients. Several longitudinal studies have been conducted to classify the phenotypes of childhood asthma, on the basis of the symptoms, triggers of wheezing illness, or pathophysiological features of the disease. These studies have provided us with important information about the different wheezing phenotypes in young children and about potential mechanisms and risk factors for the development of chronic asthma. The goal of these studies was to provide a better insight into the causes and natural course of childhood asthma. It is well-known that complicated interactions between genes and environmental factors contribute to the development of asthma. Because childhood is a period of rapid growth in both the lungs and the immune system, developmental factors should be considered in the pathogenesis of childhood asthma. The pulmonary system continues to grow and develop until linear growth is completed. Longitudinal studies have reported significant age-related immune development during postnatal early life. These observations suggest that the phenotypes of childhood asthma vary among children and also in an individual child over time. Improved classification of heterogeneous conditions of the disease will help determine novel strategies for primary and secondary prevention and for the development of individualized treatment for childhood asthma.

To evaluate the effects on growth of inhaled corticosteroid treatment (ICT) and of the quality of control of asthma, height velocity was studied in 58 prepubertal children attending a specialist asthma clinic because of chronic asthma that was difficult to control. The height velocity standard deviation (SD) score was maximal when the asthma was well controlled both before (0.01) and after (-0.07) starting ICT. It was least when the asthma was poorly controlled both before (-1.50) and after (-1.55) starting ICT. The effectiveness of control correlated significantly with the height velocity SD score, both before and after ICT was started. No evidence was found that the administration of ICT has an adverse effect on growth.

articles published in English since 2000 were considered. The search identified 29 studies; 8 additional studies were found by hand search, generating 37 studies. RESULTS: Of the 37 studies investigating biological treatments of asthma, 5 were on the effects of anti-IgE (omalizumab); 12 on anti-IL-5; 8...... TSLP, IL-9, and TNF-α lacked convincing effectiveness. CONCLUSION: Research on the biological treatment of asthma shows promising results. While anti-IgE (omalizumab) has been used in the treatment of asthma for some years, anti-IL-5 has recently been approved for use. The efficacy of results of other...... large studies with a longer duration is needed to draw a firm conclusion. Such studies should not only focus on clinical outcomes, but also consider asthma-related quality of life. Knowledge on the asthma phenotypes and identification of biomarkers associated with these will be useful for physicians...

Bacterial pneumonia has hitherto been considered the key cause of the high respiratory morbidity and mortality in children under five years of age (under-5s) in low-income countries, while asthma has not been stated as a significant reason. This paper explores the definitions and concepts...... of pneumonia and asthma/wheezing/bronchiolitis and examines whether asthma in under-5s may be confused with pneumonia. Over-diagnosing of bacterial pneumonia can be suspected from the limited association between clinical pneumonia and confirmatory test results such as chest x-ray and microbiological findings...... and poor treatment results using antibiotics. Moreover, children diagnosed with recurrent pneumonia in infancy were often later diagnosed with asthma. Recent studies showed a 10-15% prevalence of preschool asthma in low-income countries, although under-5s with long-term cough and difficulty breathing...

Asthma is not a single disease, but an umbrella term for a number of distinct diseases, each of which are caused by a distinct underlying pathophysiological mechanism. These discrete disease entities are often labelled as 'asthma endotypes'. The discovery of different asthma subtypes has moved from subjective approaches in which putative phenotypes are assigned by experts to data-driven ones which incorporate machine learning. This review focuses on the methodological developments of one such machine learning technique-latent class analysis-and how it has contributed to distinguishing asthma and wheezing subtypes in childhood. It also gives a clinical perspective, presenting the findings of studies from the past 5 years that used this approach. The identification of true asthma endotypes may be a crucial step towards understanding their distinct pathophysiological mechanisms, which could ultimately lead to more precise prevention strategies, identification of novel therapeutic targets and the development of effective personalized therapies.
Inflammation is an essential component of asthma pathophysiology. While beta(2)-agonists are often used for short-term relief of acute bronchospasm, anti-inflammatory agents are required for the long-term management of chronic inflammation in this disease. Corticosteroids have emerged as the first......-line anti-inflammatory therapy for asthma management. However, in some patients, especially children, the high doses of corticosteroids that may be required to control features of hyperresponsiveness, including exercise-induced asthma, raise safety concerns. Thus, there is a need for complementary anti......-inflammatory, steroid-sparing agents in asthma therapy. Several inflammatory mediators have been targeted in an attempt to thwart this inflammatory process, but so far with little success. The cysteinyl leukotrienes (CysLT), LTC(4), LTD(4), and LTE(4), have been shown to be essential mediators in asthma, making them...

The aim of this study was to estimate the relative influence of genetic and environmental factors on the aetiology of asthma. The classic twin study design was used to analyse data on self-reported asthma obtained by a questionnaire mailed to 34,076 individuals, aged 12-41 yrs and originating from...... in the monozygotic than in the dizygotic twins. Using biometric modelling, a model including additive genetic and nonshared environmental effects provided the best overall fit to the data. According to this model, 73% of the variation in liability to asthma was explained by genetic factors. No sex difference or age......-dependency in the magnitude of genetic effects was observed. The biometric analysis emphasized a major influence of genetic factors in the aetiology of asthma. However, a substantial part of the variation in liability to asthma is due to the impact of environmental factors specific to the individual. There is no evidence...

Psychological distress of patients with asthma may be reduced when they learned to live with their illness. Asthma can change the psychological and personality characteristics. We aim to investigate the psychological and personality characteristics of patients with asthma using MMPI (Minnesota Multiphasic Personality Inventory). Thirty-three adult patients with asthma (23 female and 10 male) and 20 healthy controls (14 females and 6 males) were enrolled in this study. Psychometric evaluation was made with the Turkish version of the MMPI. The patients were separated into two groups according to the duration of symptoms (recent-onset asthma introvert. Patients with long-standing asthma have less psychological distress, suggesting that learned to cope with his illness. © 2016 John Wiley & Sons Ltd.

Full Text Available Asthma is a heterogeneous disease with variability among patients in characteristics such as lung function, symptoms and control, body weight, markers of inflammation, and responsiveness to glucocorticoids (GC. Cluster analysis of well-characterized cohorts can advance understanding of disease subgroups in asthma and point to unsuspected disease mechanisms. We utilized an hypothesis-free cluster analytical approach to define the contribution of obesity and related variables to asthma phenotype.In a cohort of clinical trial participants (n = 250, minimum-variance hierarchical clustering was used to identify clinical and inflammatory biomarkers important in determining disease cluster membership in mild and moderate persistent asthmatics. In a subset of participants, GC sensitivity was assessed via expression of GC receptor alpha (GCRα and induction of MAP kinase phosphatase-1 (MKP-1 expression by dexamethasone. Four asthma clusters were identified, with body mass index (BMI, kg/m(2 and severity of asthma symptoms (AEQ score the most significant determinants of cluster membership (F = 57.1, p<0.0001 and F = 44.8, p<0.0001, respectively.

Objectives Previous research has established links between child, family, and neighborhood disadvantages and child asthma. We add to this literature by first characterizing neighborhoods in Houston, TX by demographic, economic, and air quality characteristics to establish differences in pediatric asthma diagnoses across neighborhoods. Second, we identify the relative risk of social, economic, and environmental risk factors for child asthma diagnoses. Methods We geocoded and linked electronic pediatric medical records to neighborhood-level social and economic indicators. Using latent profile modeling techniques, we identified Advantaged, Middle-class, and Disadvantaged neighborhoods. We then used a modified version of the Blinder-Oaxaca regression decomposition method to examine differences in asthma diagnoses across children in these different neighborhoods. Results Both compositional (the characteristics of the children and the ambient air quality in the neighborhood) and associational (the relationship between child and air quality characteristics and asthma) differences within the distinctive neighborhood contexts influence asthma outcomes. For example, unequal exposure to PM 2.5 and O 3 among children in Disadvantaged and Middle-class neighborhoods contribute to asthma diagnosis disparities within these contexts. For children in Disadvantaged and Advantaged neighborhoods, associational differences between racial/ethnic and socioeconomic characteristics and asthma diagnoses explain a significant proportion of the gap. Conclusions for Practice Our results provide evidence that differential exposure to pollution and protective factors associated with non-Hispanic White children and children from affluent families contribute to asthma disparities between neighborhoods. Future researchers should consider social and racial inequalities as more proximate drivers, not merely as associated, with asthma disparities in children.
There are few studies pertaining to asthma patients' views on complementary and alternative medicine (CAM). The driving question behind the study is why some asthma patients choose noncompliance to conventional western medicine and resort to other modalities, often deemed as being 'alternative,' 'complementary,' or 'integrated.' Does the patients' emancipation movement lead to greater awareness of the benefits of alternative medicine? Does the patients' identity as asthma sufferers play a role in their decision? Case studies based on semistructured interviews were conducted between June 2009 and January 2010 with 19 asthma patients in The Netherlands who have chosen complementary and alternative medicine (CAM). Patients were contacted through online forum of Dutch asthma patients' organization Astma Fonds. We have discovered that on the whole patients in the present study were well informed about risks and benefits of both prescribed and alternative medicines. We have argued that noncompliance to medical regime by some asthma patients can be explained by the rationality of their choice based on evidence of clinical trials of commonly assigned asthma medication as well as partial and anecdotal evidence of the benefits of CAM therapies. It is the patients themselves who, by invoking the same evidence-based dominant paradigm choose to address the conflict between protagonists of 'conventional,' western medicine and other modalities. The author argues that asthma patients' noncompliance with (Western) medical regime and choice for alternative medical treatment of asthma is a matter of rational choice informed by evidence-based awareness. This evidence-based rationality particularly refers here to the patients' awareness of the rather controversial results of clinical trials of commonly used asthma medicines, particularly those containing elements of budesonide (Pulmicort), an anti-inflammatory corticosteroid, and formoterol (Oxis, Foradil), a rapid-acting and long

The relationship between age and asthma phenotypes is important as population is ageing, asthma is becoming common in older ages and recently developed treatments for asthma are guided by phenotypes. The aim of this study is to evaluate whether age is associated with specific asthma phenotypes. This is a cross-sectional study. We included subjects with asthma of varied degrees of severity. Subjects underwent spirometry, skin prick test to aeroallergens, answered the Asthma Control Questionnaire and had blood samples collected. We performed binary logistic regression analysis to evaluate whether age is associated with asthma phenotypes. We enrolled 868 subjects. In comparison with subjects ≤ 40 years, older subjects had high odds of irreversible airway obstruction (from 41 to 64 years, OR: 1.83 (95% CI: 1.32-2.54); ≥65 years, OR: 3.45 (2.12-5.60)) and severe asthma phenotypes (from 41 to 64 years, OR: 3.23 (2.26-4.62); ≥65 years, OR: 4.55 (2.39-8.67)). Older subjects had low odds of atopic (from 41 to 64 years, OR: 0.56 (0.39-0.79); ≥65 years, OR: 0.47 (0.27-0.84)) and eosinophilic phenotypes (from 41 to 64 years, OR: 0.63 (0.46-0.84); ≥65 years, OR: 0.39 (0.24-0.64)). Older subjects with asthma have low odds of atopic and eosinophilic phenotypes, whereas they present high odds of irreversible airway obstruction and severe asthma. © 2017 Asian Pacific Society of Respirology.

Objectives There is evidence that exposure to air pollution affects asthma, but the effect of air pollution on asthma severity has not been addressed. The aim was to assess the relation between asthma severity during the past 12 months and home outdoor concentrations of air pollution. Methods Asthma severity over the last 12 months was assessed in two complementary ways among 328 adult asthmatics from the French Epidemiological study on the Genetics and Environment of Asthma (EGEA) examined between 1991 and 1995. The 4-class severity score integrated clinical events and type of treatment. The 5-level asthma score is based only on the occurrence of symptoms. Nitrogen dioxide (NO2), sulphur dioxide (SO2) and ozone (O3) concentrations were assigned to each residence using two different methods. The first was based on the closest monitor data from 1991–1995. The second consisted in spatial models that used geostatistical interpolations and then assigned air pollutants to the geo-coded residences (1998). Results Higher asthma severity score was significantly related to the 8-hour average of ozone during April-September (O3-8hr) and the number of days (O3-days) with 8-hour ozone averages above 110 μg.m−3 (for a 36-day increase, equivalent to the inter quartile range, in O3-days, odds ratio (95% confidence interval) 2.22 (1.61–3.07) for one class difference in score). Adjustment for age, sex, smoking habits, occupational exposure, and educational level did not alter results. Asthma severity was unrelated to NO2. Both exposure assessment methods and severity scores resulted in very similar findings. SO2 correlated with severity but reached statistical significance only for the model based assignment of exposure. Conclusions The observed associations between asthma severity and air pollution, in particular O3, support the hypothesis that air pollution at levels far below current standards increases asthma severity.

The single-center double-blind, randomized controlled Managing Asthma in Pregnancy (MAP) trial in Newcastle, Australia, compared a treatment algorithm using the fraction of exhaled nitric oxide (FENO) in combination with asthma symptoms (FENO group) against a treatment algorithm using clinical symptoms only (clinical group) in pregnant asthmatic women (Australian New Zealand Clinical Trials Registry, no. 12607000561482). The primary outcome was a 50% reduction in asthma exacerbations during pregnancy in the FENO group. However, the effect of FENO-guided management on the development of asthma in the offspring is unknown. We sought to investigate the effect of FENO-guided asthma management during pregnancy on asthma incidence in childhood. A total of 179 mothers consented to participate in the Growing into Asthma (GIA) double-blind follow-up study with the primary aim to determine the effect of FENO-guided asthma management on childhood asthma incidence. A total of 140 children (78%) were followed up at 4 to 6 years of age. FENO-guided as compared to symptoms-only approach significantly reduced doctor-diagnosed asthma (25.9% vs 43.2%; odds ratio [OR], 0.46, 95% CI, 0.22-0.96; P = .04). Furthermore, frequent wheeze (OR, 0.27; 95% CI, 0.09-0.87; P = .03), use of short-acting β-agonists (OR, 0.49; 95% CI, 0.25-0.97; P = .04), and emergency department visits for asthma (OR, 0.17; 95% CI, 0.04-0.76; P = .02) in the past 12 months were less common in children born to mothers from the FENO group. Doctor-diagnosed asthma was associated with common risk alleles for early onset asthma at gene locus 17q21 (P = .01 for rs8069176; P = .03 for rs8076131), and higher airways resistance (P = .02) and FENO levels (P = .03). A causal mediation analysis suggested natural indirect effects of FENO-guided asthma management on childhood asthma through "any use" and "time to first change in dose" of inhaled corticosteroids during the MAP trial (OR: 0.83; 95% CI: 0

Monitoring the level of asthma control is important in determining the effectiveness of current treatment which may decrease the frequency and intensity of symptoms and functional limitations. Uncontrolled asthma has been associated with decreased quality of life and increased health care use. The objectives of this study were to assess the level of asthma control and identify related risk factors among persons with current asthma. Using the 2006 to 2010 BRFSS child and adult Asthma Call-back Survey, asthma control was classified as well-controlled or uncontrolled (not-well-controlled or very-poorly-controlled) using three impairment measures: daytime symptoms, night-time symptoms, and taking short-acting β2-agonists for symptom control. Multivariate logistic regression identified predictors of asthma control. Fifty percent of adults and 38.4% of children with current asthma had uncontrolled asthma. About 63% of children and 53% of adults with uncontrolled asthma were on long-term asthma control medications. Among children, uncontrolled asthma was significantly associated with being younger than 5 years, having annual household income asthma (low educational attainment, low income, cigarette smoking, and co-morbid conditions including obesity and depression) could improve asthma control.

Both asthma and obstructive sleep apnoea cause sleep disturbance, daytime sleepiness and diminished quality of life. Continuous positive airway pressure (CPAP) is efficient in reducing symptoms related to sleep apnoea. Here we report the impact of long-term use of CPAP on asthma symptoms. A survey questionnaire was distributed to all of our obstructive sleep apnoea patients with CPAP therapy in 2013. We used the Finnish version of the Asthma Control Test™ (ACT) and a visual analogue scale (0 = no symptoms, 100 = severe asthma symptoms). Asthma was defined as self-reported physician-diagnosed disease and a special reimbursement for asthma medication by the Social Insurance Institution. We sent 2577 questionnaires and received 1586 answers (61 %). One hundred ninety-seven patients were asthmatics with a prevalence of asthma among CPAP users of 13 %. We studied 152 patients (58 females) whose CPAP therapy was initiated after starting asthma medication. Their mean (SD) age was 62 (10) years, duration of CPAP 5.7 (4.7) years and their CPAP daily use was 6.3 (2.4) h. Self-reported asthma severity decreased significantly from 48.3 (29.6) to 33.1 (27.4) (p CPAP (P CPAP in patients with both asthma and obstructive sleep apnoea.

Although it is thought that inner-city areas have a high burden of asthma, the prevalence of asthma in inner cities across the United States is not known. We sought to estimate the prevalence of current asthma in US children living in inner-city and non-inner-city areas and to examine whether urban residence, poverty, or race/ethnicity are the main drivers of asthma disparities. The National Health Interview Survey 2009-2011 was linked by census tract to data from the US Census and the National Center for Health Statistics. Multivariate logistic regression models adjusted for sex; age; race/ethnicity; residence in an urban, suburban, medium metro, or small metro/rural area; poverty; and birth outside the United States, with current asthma and asthma morbidity as outcome variables. Inner-city areas were defined as urban areas with 20% or more of households at below the poverty line. We included 23,065 children living in 5,853 census tracts. The prevalence of current asthma was 12.9% in inner-city and 10.6% in non-inner-city areas, but this difference was not significant after adjusting for race/ethnicity, region, age, and sex. In fully adjusted models black race, Puerto Rican ethnicity, and lower household income but not residence in poor or urban areas were independent risk factors for current asthma. Household poverty increased the risk of asthma among non-Hispanics and Puerto Ricans but not among other Hispanics. Associations with asthma morbidity were very similar to those with prevalent asthma. Although the prevalence of asthma is high in some inner-city areas, this is largely explained by demographic factors and not by living in an urban neighborhood.

Full Text Available Abstract Background The morbidity and mortality from asthma have markedly increased since the late 1970s. The hospitalization rate, an important marker of asthma severity, remains substantial. Methods In adults with health care access, we prospectively studied 242 with asthma, aged 18–50 years, recruited from a random sample of allergy and pulmonary physician practices in Northern California to identify risk factors for subsequent hospitalization. Results Thirty-nine subjects (16% reported hospitalization for asthma during the 18-month follow-up period. On controlling for asthma severity in multiple logistic regression analysis, non-white race (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.1–8.8 and lower income (OR, 1.1 per $10,000 decrement; 95% CI, 0.9–1.3 were associated with a higher risk of asthma hospitalization. The severity-of-asthma score (OR, 3.4 per 5 points; 95%, CI 1.7–6.8 and recent asthma hospitalization (OR, 8.3; 95%, CI, 2.1–33.4 were also related to higher risk, after adjusting for demographic characteristics. Reliance on emergency department services for urgent asthma care was also associated with a greater likelihood of hospitalization (OR, 3.2; 95% CI, 1.0–9.8. In multivariate analysis not controlling for asthma severity, low income was even more strongly related to hospitalization (OR, 1.2 per $10,000 decrement; 95% CI, 1.02–1.4. Conclusion In adult asthmatics with access to health care, non-white race, low income, and greater asthma severity were associated with a higher risk of hospitalization. Targeted interventions applied to high-risk asthma patients may reduce asthma morbidity and mortality.

To compare the conventional pulmonary function test results of children with asthma or cough variant asthma (CVA). A total of 140 children, who were diagnosed with asthma or CVA from May 2010 to May 2011, were divided into acute asthma attack (n=50), asthma remission (n=50) and CVA groups (n=40); 30 healthy children were included as a control group. The forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), forced expiratory flow after 25% of vital capacity has been expelled (FEF25), forced expiratory flow after 50% of vital capacity has been expelled (FEF50), forced expiratory flow after 75% of vital capacity has been expelled (FEF75) and maximal midexpiratory flow (MMEF75/25) were measured. The mean percent predicted values of all the above indices were lower than 80% in the acute asthma attack group, with FEF50, FEF75 and MMEF75/25 declining markedly; the mean percent predicted values of FEF75 and MMEF75/25 were lower than 80% in the CVA group. All the pulmonary function indices in the acute asthma attack group were lower than those in the control group. The mean percent predicted values of FVC, FEV1, FEF25 and MMEF75/25 in the asthma remission and CVA groups were lower than in the control group. All the pulmonary function indices in the acute asthma attack group were lower than in the asthma remission and CVA groups, but there were no significant differences between the asthma remission and CVA groups. There is small and large airway dysfunction, particularly small airway dysfunction, in children with acute asthma attack. Children with CVA present mainly with mild small airway dysfunction, as do those with asthma in remission.

The aims of this survey were (1) to assess the quality of asthma treatment and control in Latin America, (2) to determine how closely asthma management guidelines are being followed, and (3) to assess perception, knowledge and attitudes related to asthma in Latin America. We surveyed a household sample of 2,184 adults or parents of children with asthma in 2003 in 11 countries in Latin America. Respondents were asked about healthcare utilization, symptom severity, activity limitations and medication use. Daytime asthma symptoms were reported by 56% of the respondents, and 51% reported being awakened by their asthma at night. More than half of those surveyed had been hospitalized, attended a hospital emergency service or made unscheduled emergency visits to other healthcare facilities for asthma during the previous year. Patient perception of asthma control did not match symptom severity, even in patients with severe persistent asthma, 44.7% of whom regarded their disease as being well or completely controlled. Only 2.4% (2.3% adults and 2.6% children) met all criteria for asthma control. Although 37% reported treatment with prescription medications, only 6% were using inhaled corticosteroids. Most adults (79%) and children (68%) in this survey reported that asthma symptoms limited their activities. Absence from school and work was reported by 58% of the children and 31% of adults, respectively. Asthma control in Latin America falls short of goals in international guidelines, and in many aspects asthma care and control in Latin America suffer from the same shortcomings as in other areas of the world.

The T lymphocyte takes primacy in driving the inflammatory response through upregulation of cytokines, specifically those encoded in the IL-4 gene cluster: IL-4 and IL-13 (IgE isotype switching; IL-3, IL-5 and GM-CSF (eosinophil and basophil recruitment; and IL-9 (mast cell maturation. Additional cytokines of importance include TNFa and a range of related C-x-C and C-C cytokines. Although allergens are involved in initiating the Th-2 T-cell response, other factors are likely to operate that expand and maintain the inflammatory reaction. These include a potential role for superantigens and autoimmune mechanisms as well as the recruitment of accessory cytokine producing cells, especially mast cells and eosinophils. Leucocytes recruited from the microvasculature through interactions with specific adhesion molecules release an array of mediators, which in addition to causing bronchoconstriction also lead to damage to the epithelium and underlying structures. Neutral proteases from mast cells, metalloproteases from eosinophils and an array of mediators from the formed elements of the airway all contribute to the tissue destruction remodelling process. It was concluded that asthma is a dynamic disease process involving an interplay between inflammation and repair processes and that the differing proportions of these could account for the various disease phenotypes associated with severity and progression.
Full Text Available Introduction: The coexistence of asthma and chronic rhinosinusitis (CRS is more common than expected given their individual prevalence in the general population and may affect patient’s quality of life. The aim of this study was to evaluate the prevalence of asthma in chronic rhinosinusitis in Mashhad, Northeast Iran. Materials and Methods: This study was performed in two university hospital from November 2012 for 12 months. In total, 153 patients with chronic rhinosinusitis were enrolled and referred to a particular pulmonologist for asthma evaluation. Results: The mean age of participants was 40.54±13.11 years, and 41.8% were male. In total, 63.4% of patients had the polypoid form of CRS. The proportion of patients in this study with asthma was 41.8%, compared with a general asthma prevalence in this region of 13.5%. Conclusion: There is a high prevalence of asthma among patients with CRS, but it often remains undiagnosed. Asthma in CRS patients should be diagnosed and treated in order to improve patient’s quality of life. We recommend an evaluation of the lower airways in all of these patients as well as further studies in this field.

Childhood asthma is a substantial health burden in Thailand. Due to a lack of pediatric respiratory specialists (pediatric pulmonologists and allergists; RS), most Thai children are cared for by general pediatricians (pediatric primary care providers (PCP)). We investigated whether current practices of Thai pediatricians complied with asthma guidelines and compared practices (diagnosis and treatments) provided by PCP and RS. A cross-sectional study was conducted using electronic surveys including four case scenarios of different asthma phenotypes distributed to Thai pediatricians. Asthma diagnosis and management were evaluated for compliance with standard guidelines. The practices of PCP and RS were compared. From 800 surveys distributed, there were 405 respondents (51%). Most respondents (81%) were PCP, who preferred to use clinical diagnosis rather than laboratory investigations to diagnose asthma. For acute asthmatic attacks, 58% of the pediatricians prescribed a systemic corticosteroid. For uncontrolled asthma, 89% of the pediatricians prescribed at least one controller. For exercise-induced bronchospasm, 55% of the pediatricians chose an inhaled bronchodilator, while 38% chose a leukotriene receptor antagonist (LTRA). For virus-induced wheeze, 40% of the respondents chose an LTRA, while 15% chose inhaled corticosteroids (ICS). PCP prescribed more oral bronchodilators (31% vs. 18%, p = 0.02), antibiotics (20% vs. 6%, p attack. Most of the Thai pediatricians' practices toward diagnosis and treatment of acute asthmatic attack and uncontrolled asthma conform to the guidelines. PCP prescribed more oral bronchodilators, antibiotics, and antihistamines than RS.

Omalizumab is a recombinant humanized anti-IgE monoclonal antibody approved in the US for moderate to severe persistent allergic asthma (severe persistent asthma in the European Union), uncontrolled despite treatment with inhaled corticosteroids and long-acting beta2 agonists. It reduces asthma exacerbations, symptoms, oral corticosteroid doses, and improves quality of life. Omalizumab may have an antiviral effect when used as a preventive therapy for fall exacerbations in children and teenagers. Two proof-of-concept studies have evaluated omalizumab in nonatopic asthma and showed that it is safe and possibly efficacious in some patients. Omalizumab has been successfully studied as add-on to specific immunotherapy in moderate allergic asthma. Its safety in pregnancy has been assessed in the EXPECT registry. Case series also report positive effects in cases of allergic bronchopulmonary aspergillosis, and in nasal disorders frequently associated with asthma. Last, omalizumab may have corticosteroid-sparing effect in a subset of patients with eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome). Recent studies argue in favor of positive effects of omalizumab beyond its current indications in asthma. Well-designed studies are needed in order to demonstrate the safety and efficacy of omalizumab in these possible novel indications.

This review presents seven national asthma programmes to support the European Asthma Research and Innovation Partnership in developing strategies to reduce asthma mortality and morbidity across Europe. From published data it appears that in order to influence asthma care, national/regional asthma programmes are more effective than conventional treatment guidelines. An asthma programme should start with the universal commitments of stakeholders at all levels and the programme has to be endorsed by political and governmental bodies. When the national problems have been identified, the goals of the programme have to be clearly defined with measures to evaluate progress. An action plan has to be developed, including defined re-allocation of patients and existing resources, if necessary, between primary care and specialised healthcare units or hospital centres. Patients should be involved in guided self-management education and structured follow-up in relation to disease severity. The three evaluated programmes show that, thanks to rigorous efforts, it is possible to improve patients' quality of life and reduce hospitalisation, asthma mortality, sick leave and disability pensions. The direct and indirect costs, both for the individual patient and for society, can be significantly reduced. The results can form the basis for development of further programme activities in Europe.

Full Text Available This review summarizes the results of epidemiological studies focusing on the detrimental effects of home environmental factors on asthma morbidity in adults. We reviewed the literature on indoor air quality (IAQ, physical and sociodemographic factors, and asthma morbidity in homes, and identified commonly reported asthma, allergic, and respiratory symptoms involving the home environment. Reported IAQ and asthma morbidity data strongly indicated positive associations between indoor air pollution and adverse health effects in most studies. Indoor factors most consistently associated with asthma and asthma-related symptoms in adults included fuel combustion, mold growth, and environmental tobacco smoke. Environmental exposure may increase an adult’s risk of developing asthma and also may increase the risk of asthma exacerbations. Evaluation of present IAQ levels, exposure characteristics, and the role of exposure to these factors in relation to asthma morbidity is important for improving our understanding, identifying the burden, and for developing and implementing interventions aimed at reducing asthma morbidity.
Asthma is a chronic airway disease that affects all ages, but does this definition also include the elderly? Traditionally, asthma has been considered a disease of younger age, but epidemiological studies and clinical experience support the concept that asthma is as prevalent in older age as it is in the young. With the ever-increasing elderly population worldwide, the detection and proper management of the disease in old age may have a great impact from the public health perspective. Whether asthma in the elderly maintains the same characteristics as in young populations is an interesting matter. The diagnostic process in older individuals with suspected asthma follows the same steps, namely a detailed history supported by clinical examination and laboratory investigations; however, it should be recognised that elderly patients may partially lose reversibility of airway obstruction. The correct interpretation of spirometric curves in the elderly should take into account the physiological changes in the respiratory system. Several factors contribute to delaying the diagnosis of asthma in the elderly, including the age-related impairment in perception of breathlessness. The management of asthma in advanced age is complicated by the comorbidities and polypharmacotherapy, which advocate for a comprehensive approach with a multidimensional assessment. It should be emphasised that older age frequently represents an exclusion criterion for eligibility in clinical trials, and current asthma medications have rarely been tested in elderly asthmatics. Ageing is associated with pharmacokinetic changes of the medications. As a consequence, absorption, distribution, metabolism and excretion of antiasthmatic medications can be variably affected. Similarly, drug-to-drug interactions may reduce the effectiveness of inhaled medications and increase the risk of side-effects. For this reason, we propose the term “geriatric asthma” be preferred to the more generic “asthma in the

Animal data have suggested that the transient receptor potential ankyrin-1 (TRPA1) ion channel plays a key role in promoting airway inflammation in asthma and may mediate effects of paracetamol on asthma, yet confirmatory human data are lacking. To study associations of TRPA1 gene variants with childhood asthma and total IgE concentration, and interactions between TRPA1 and prenatal paracetamol exposure on these outcomes. We analysed associations between 31 TRPA1 single nucleotide polymorphisms (SNPs) and current doctor-diagnosed asthma and total IgE concentration at 7.5 years in the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort. We sought to confirm the most significant associations with comparable outcomes in the Prevention and Incidence of Asthma and Mite Allergy (PIAMA) and Generation R birth cohorts. In ALSPAC, we explored interactions with prenatal paracetamol exposure. In ALSPAC, there was strong evidence for association between six SNPs and asthma: rs959974 and rs1384001 (per-allele odds ratio for both: 1.30 (95% CI: 1.15-1.47), p = 0.00001), rs7010969 (OR 1.28 (1.13-1.46), p = 0.00004), rs3735945 (OR 1.30 (1.09-1.55), p = 0.003), rs920829 (OR 1.30 (1.09-1.54), p = 0.004) and rs4738202 (OR 1.22 (1.07-1.39), p = 0.004). In a meta-analysis across the three cohorts, the pooled effect estimates confirmed that all six SNPs were significantly associated with asthma. In ALSPAC, TRPA1 associations with asthma were not modified by prenatal paracetamol, although associations with IgE concentration were. This study suggests that TRPA1 may play a role in the development of childhood asthma. (249 words). © 2016 The Authors Pediatric Allergy and Immunology Published by John Wiley & Sons Ltd.

Asthma has been systematically stigmatized in Hollywood feature films, including films seen by children. Through content analysis of 66 movies containing one or more scenes showing asthma, and through informant interviews with a dozen U.S. children about representative scenes, the study explores how stigmatizing portrayals are interpreted, accepted, or resisted. Children suffering from asthma actively counterargued with incriminating excerpts, but in some respects their healthy friends were less critical. Overall, children viewed stigmatizing scenes in terms of the social interaction and the social ethics entailed. They did not scrutinize the characters for damaged selfhood, per se, but dwelled on the social processes out of which stigma is erected.

Allergic diseases and asthma are the result of complex interactions between genetic predisposition and environmental factors. Asthma is one of the most prevalent chronic disease among children. In this article we review some environmental factors like: allergen exposition, tobacco, bacteria, microbial components, diet, obesity and stress, which influences during intrauterine and infancy life in the epigenetic regulation of asthma and allergic diseases. The review has been done in three models: in-vitro, animal and human. Copyright © 2016 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.

For successful long-term asthma care, self-management education is a cornerstone. Little is known about associations between patients' interest in education, asthma control and care delivery. We compared patients' characteristics, asthma control and patients' perspective about asthma care in subjects with and without interest in asthma education. Moreover, we assessed reasons, why patients denied participating in asthma education. Baseline data of 223 patients with asthma (age 43 ± 12 years, 38% male, 58% non-smokers, 13% current smokers), who participated in a multicentre longitudinal controlled study, are reported. At baseline, patients completed the Asthma Control Test (ACT), the Patient Assessment Chronic Illness Care questionnaire (PACIC 5A) and stated their interest in an asthma education programme. Overall, 34% of all participants showed uncontrolled asthma. One hundred and twenty-five (56%) patients were interested in education. Compared to patients without interest, they were characterised by male gender (p = 0.013), worse asthma control (p < 0.001), and perception of lower quality of chronic asthma care delivery, in particular lower self-management support (p < 0.001). Main reasons for rejecting asthma education were having sufficient asthma knowledge, having only mild asthma, receiving adequate medical support and lack of time. More than half of the patients were interested in asthma education. Interest was associated with worse asthma control and lower receipt of care according to the Chronic Care Model. Considering these aspects, this approach may help to improve care quality and allow targeting interventions to those patients who are interested in becoming active participants in their care and who might benefit most.

Although asthma is the most common cause of cough, wheeze, and dyspnea in children and adults, asthma is often attributed inappropriately to symptoms from other causes. Cough that is misdiagnosed as asthma can occur with pertussis, cystic fibrosis, primary ciliary dyskinesia, airway abnormalities such as tracheomalacia and bronchomalacia, chronic purulent or suppurative bronchitis in young children, and habit-cough syndrome. The respiratory sounds that occur with the upper airway obstruction caused by the various manifestations of the vocal cord dysfunction syndrome or the less common exercise-induced laryngomalacia are often mischaracterized as wheezing and attributed to asthma. The perception of dyspnea is a prominent symptom of hyperventilation attacks. This can occur in those with or without asthma, and patients with asthma may not readily distinguish the perceived dyspnea of a hyperventilation attack from the acute airway obstruction of asthma. Dyspnea on exertion, in the absence of other symptoms of asthma or an unequivocal response to albuterol, is most likely a result of other causes. Most common is the dyspnea associated with normal exercise limitation, but causes of dyspnea on exertion can include other physiologic abnormalities including exercise-induced vocal cord dysfunction, exercise-induced laryngomalacia, exercise-induced hyperventilation, and exercise-induced supraventricular tachycardia. A careful history, attention to the nature of the respiratory sounds that are present, spirometry, exercise testing, and blood-gas measurement provide useful data to sort out the various causes and avoid inappropriate treatment of these pseudo-asthma clinical manifestations.

Providing asthma education about controller medication use and appropriate management of asthma exacerbation are the keys to improving the disease outcome. Many asthma guidelines recommend that physicians provide written asthma action plan (WAAP) to all of their asthmatic patients. However, the benefit of WAAP is unclear. Thus, we have created a new WAAP which is simplified in Thai and more user friendly. To determine the effectiveness of the newly developed asthma action plan in management of children with asthma. Asthmatic children who meet inclusion criteria all received the WAAP and they were followed up for 6 months with measurement of outcome variables, such as asthma exacerbation that required emergency room visit, unscheduled OPD visit, admission and school absence in order to compare with the past 6 months before receiving the WAAP. The analyzed outcomes of forty-nine children show significantly reduced emergency room visit (P-value 0.005), unscheduled OPD visit (P-value 0.046), admission days (P-value 0.026) and school absence days (P-value 0.022). Well controlled group and mild severity group were not the factors that contribute to decreased emergency room visit but step up therapy may be the co-factor to decreased ER visit. The results of this study suggest that the provision of newly developed WAAP is useful for improving self-care of asthma patients and reducing asthma exacerbation.

Clinical asthma studies across different age groups (ie, cross-age studies) can potentially offer insight into the similarities, differences, and relationships between childhood and adult asthma. The National Institutes of Health's Asthma Research Network (AsthmaNet) is unique and innovative in that it has merged pediatric and adult asthma research into a single clinical research network. This combination enhances scientific exchange between pediatric and adult asthma investigators and encourages the application of cross-age studies that involve participants from multiple age groups who are generally not studied together. The experience from AsthmaNet in the development of cross-age protocols highlights some of the issues in the evaluation of cross-age research in asthma. The aim of this review is to summarize these challenges, including the selection of parallel cross-age clinical interventions, identification of appropriate controls, measurement of meaningful clinical outcomes, and various ethical and logistic issues.

This study sought to investigate parents' needs and preferences for school-based asthma support in Saudi Arabian primary schools. Semi-structured qualitative interviews were conducted in the period between November 2015 and February 2016, with a convenience sample that comprised Saudi parents and carers of children with asthma. Recruitment of participants was primarily driven through Saudi primary schools; passive snowballing and social networks were used to boost participation rates further. Interviews were audio-recorded, transcribed verbatim, translated and data were thematically organised using a latent content analysis approach. Twenty interviews were conducted. Six themes emerged from the interviews and were grouped into three major categories: (1) general asthma management issues; (2) school-based asthma management issues; and (3) communication dissatisfaction. Participants expressed concern at schools' social and physical environments and a lack of confidence in the ability of schools to manage their child's asthma, especially when their child was ill. Most of the participants advocated for staff training and school community engagement to improve the management of asthma in Saudi primary schools. This research clearly describes a need for school-based asthma support, including asthma-related policies, procedures and education on asthma and first aid in Saudi primary schools.

Full Text Available Introduction: Asthma is a chronic inflammatory disease which has increased during the last 20 years, putting a strain on medical resources, particularly severe forms of the disease. Treatment in such cases is inhaled corticosteroids and beta agonist drugs that can produce a range of side effects. The aim of this study is to identify echocardiograph abnormalities and correlate them with severity of disease. Methodology: Eight-seven outpatients were selected at the asthma unit of the Gaffree Guinle University Hospital (HUGG. Each patient underwent spirometry, electrocardiogram (ECG and echocardiogram (ECO during the trial within a month maximum. Echocardiograph abnormalities found related to degree of asthma. Statistical analysis was made by nonparametric tests. Results: We found significant differences (pÂ â¤Â 0.05 for age, disease duration and haemoglobin saturation (SaO2 between the moderate and severe groups. In the sample a high prevalence of tricuspid insufficiency (41.4% was identified. Conclusions: ECO identified a series of abnormalities that were not always dependent on severity of disease. ECO can identify pulmonary hypertension through calculation of mean pressure of the pulmonary artery.

Full Text Available Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

In this article, we analyze qualitative data from a purposeful sample of limited English proficiency (LEP) asthma health caregivers. We used ethnically concordant, semistructured, in-depth Spanish-language interviews and a follow-up focus group to explore issues related to communication during pediatric asthma encounters in medical settings. Inductive coding of Spanish transcripts by a bilingual research team was performed until thematic saturation was reached. Several key findings emerged. LEP caregivers encountered significant asthma burdens related to emotional stress, observed physical changes, and communication barriers. Language-discordant communication and the use of ad hoc interpreters were common. This finding is complex, and was influenced by perceptions of interpreter availability, delays in care, feelings of mistrust toward others, and individual emotional responses. Language-concordant education and suitable action plans were valued and desired. We discuss a revealing depiction of the LEP caregiver experience with asthma health communication and recommend areas for further inquiry. © The Author(s) 2014.

Full Text Available It is important to assess patients of difficult/therapy resistant asthma carefully in order to identify whether there are any correctable factors that may contribute to their poor control. It is critical to make a diagnosis of asthma and to exclude other airway diseases. A 65-years-old lady presented with repeated acute episodes of dyspnoea and wheezing. She was on regular medication for bronchial asthma for 18 years. There was no history of foreign body aspiration or loss of consciousness. Her chest radiograph was normal. She showed poor response to corticosteroids and bronchodilators. Fibreoptic bronchoscopy (FOB showed intracordal cyst of the left vocal cord and 1cm size irregular piece of betel nut in right main bronchus, which was removed endoscopically with the help of dormia basket, following which her condition improved and asthma was controlled on inhaled bronchodilators.

Therapy for bronchial asthma should be preventive when possible. Around-the-clock treatment with theophylline is a new way of using an old drug. Beta2-adrenergic receptor stimulators, cromolyn sodium, and steroids in aerosol form are new drugs that are useful in treatment of asthma. The good news with respect to drug treatment of asthma is that in addition to the old reliable medications which have provided good relief-including epinephrine, ephedrine, isoproterenol, aminophylline, and steroids given orally and parenterally-new drugs are available which have been extremely helpful in controlling symptoms in many patients. The bad news is that none of the new agents is a panacea and that many of them have significant undesirable side effects. It is the physician's responsibility to be wary of the new drugs for asthma and to use them appropriately.

Despite great efforts in establishing optimal asthma management, asthma may remain uncontrolled. To effectively manage chronic diseases, such as asthma, it is important to train patients in self-management skills. The aim of this study was to assess the potential benefit of standardised asthma education in Switzerland for asthma control and patients' perception of received asthma care and of self-management support. For this multicentre longitudinal controlled study, asthma patients were recruited in Switzerland. The Asthma Control Test (ACT) was used to assess asthma control. The Patient Assessment of Chronic Illness Care questionnaire (PACIC 5A) was applied to evaluate received health-care services and self-management support. Patients were offered the possibility to attend asthma education sessions conducted by the Swiss Lung League and Swiss Allergy Centre. After 1 year, attenders and non-attenders completed the questionnaires again. Changes in ACT and PACIC 5A scores were analysed using dependent t tests. Overall, 223 patients with asthma were investigated (mean age 43 ± 12 years, 38% male, 13% current smokers, 29% ex-smokers). Sixty-one (27%) patients attended education sessions. Both groups had improved asthma control at follow-up (attenders: t(56) = -3.2, r = 0.4 [medium effect size], p = 0.002; non-attenders: t(141) = -2.6, r = 0.2 [small effect size], p = 0.010). Attenders improved in PACIC and 5A sum scores (t(50) = -3.6, r = 0.5 [medium effect size], p = 0.001). A comprehensive self-management asthma education programme in Switzerland improved asthma control and patients' perception of received asthma care and of self-management support. Professionals should motivate patients to attend asthma education in order to become active partners in managing their disease. © 2017 S. Karger AG, Basel.

The relationship between asthma controller medication use and exacerbation rates over time is unclear at the population level. To estimate the change in asthma controller medication use between 2 time periods as measured by the controller-to-total asthma medication ratio and its association with changes in asthma exacerbation rates between 1997-1998 and 2004-2005. The study design was a cross-sectional population-level comparison between individuals from 1997-1998 and 2004-2005. Study participants were individuals aged 5 to 56 years identified as having asthma in the Medical Expenditure Panel Survey (MEPS). The main outcome measures were a controller-to-total asthma medication ratio greater than 0.5 and asthma exacerbation rates (dispensing of systemic corticosteroid or emergency department visit/hospitalization for asthma) in 1997-1998 compared with 2004-2005. The proportion of individuals with a controller-to-total asthma medication ratio greater than 0.5, when adjusted for other demographic factors, has improved by 16.1% (95% CI: 10.8%, 21.3%) for all individuals from 1997-1998 to 2004-2005. Annual asthma exacerbation rates did not change significantly in any group from 1997-1998 to 2004-2005 (0.27/year to 0.23/year). African American and Hispanic individuals with asthma had higher asthma exacerbation rates and a lower proportion with a controller-to-total asthma medication ratio greater than 0.5 than whites in both 1997-1998 and 2004-2005; however, these differences were not statistically significant. An increase in asthma controller-to-total medication ratio in a sample reflective of the US population was not associated with a decreased asthma exacerbation rate comparing 1997-1998 and 2004-2005.

The high burden of asthma indicates suboptimal control of this chronic condition. This review describes approaches for establishing asthma control based on an understanding of potential issues in the achievement and maintenance of asthma control, recent changes in asthma management guidelines that facilitate attainment of treatment goals, and the importance of the healthcare provider-patient partnership to emphasize treatment based on asthma control. Review of the published literature, asthma management guidelines, and patient asthma education resources. Asthma control is best achieved by patient-oriented versus disease-oriented management strategies that incorporate a combination of pharmacologic and nonpharmacologic treatment modalities. Tools that assess and monitor asthma may facilitate the achievement and maintenance of asthma control. Key components of an optimal management strategy include solid partnerships between healthcare providers and patients, comprehensive patient and caregiver education, personalized written asthma action plans, patient-reported evaluation of symptom control, appropriate drug therapy, strategies for improving compliance with asthma medication regimens, and a treatment algorithm that outlines the facets of asthma management. Information presented in this article will guide nurse practitioners in helping patients with asthma achieve and maintain long-term disease control.

Asthma mortality rates have increased worldwide during the past several years despite the increased availability of new and effective medications. Few studies show reliable data from Latin American countries. To determine asthma mortality rates from 1984 to 1998 and to relate mortality to sales of asthma medications. We conducted a retrospective epidemiologic study in the total population of Uruguay. Data were obtained from the Department of Statistics of the Ministry of Public Health. Trends in mortality rates were analyzed using linear regression procedures. Spearman rank correlations were used to relate mortality rates to sales of asthma medications. The mean overall mortality rate was 5.10 per 100,000 during the period 1984 to 1998, (range 6.08 to 3.39) and showed a decreasing trend (P = 0.001). During the period 1995 to 1998, a more pronounced decrease was observed (mean mortality rate, 4.10 per 100,000). In the 5- to 34-year-old age group the mean mortality rate was 0.43 (range 0.65 to 0.13). Similarly, the mortality rate in this age group decreased particularly in the 1994 to 1998 period (mean 0.19; P = 0.005). Finally, the mortality rate was inversely correlated with sales of inhaled corticosteroids; for the overall mortality rate, p = -0.71, P = 0.003; for 5- to 34-year-old age group, p = -0.63, P = 0.01. Although mortality attributable to asthma seems to be decreasing, the overall mortality rate is still high compared with more economically developed countries. A more pronounced decrease in asthma mortality has been seen in the 5- to 34-year-old group. At present, Uruguay is a Latin American country with a low rate of asthma mortality. This is probably related to the use of new therapies to treat asthma.

Full Text Available ABSTRACT Objective: To evaluate risk factors associated with asthma symptoms in adolescents in the 13- to 14-year age bracket. Methods: This was a cross-sectional study involving adolescents enrolled in randomly selected public schools in the city of Belo Horizonte, Brazil, and conducted with the use of the International Study of Asthma and Allergies in Childhood (ISAAC questionnaire and its supplementary module for risk factor assessment. The ISAAC questionnaire was completed by the students themselves, whereas the supplementary questionnaire was completed by their parents or legal guardians. Variables showing p ≤ 0.25 in the univariate analysis were included in the multivariate analysis. Stepwise regression with backward elimination was used for variable selection. Results: We evaluated 375 adolescents, 124 (33.1% of whom had asthma symptoms. The final multivariate analysis model revealed that asthma symptoms were associated with birth weight < 2,500 g (p < 0.001, day care center or nursery attendance (p < 0.002, maternal history of asthma (p < 0.001, contact with animals during the first year of life (p < 0.027, current contact with animals outside the home (dogs, cats, or farm animals; p < 0.005, and more than 20 cigarettes per day smoked by parents or other household members (p < 0.02. Conclusions: Exposure to animals in and outside the home is associated with asthma symptoms, as is environmental tobacco smoke exposure. Families, health professionals, and administrators of health care facilities should take that into account in order to prevent asthma and reduce asthma morbidity.

Asthma is the most prevalent chronic respiratory disease both in children and adults and resembles a complex syndrome rather than a single disease. Different methods have been developed to better characterise distinct asthma phenotypes in childhood and adulthood. In studies of adults, most phenotyping relies on biomaterials from the lower airways; however, this information is missing in paediatric studies because of restricted accessibility. Few patients show symptoms throughout childhood, adolescence, and adulthood. Risk factors for this might be genetics, family history of asthma and atopy, infections early in life, allergic diseases, and lung function deficits. In turn, a large proportion of children with asthma lose their symptoms during school age and adolescence. This improved prognosis, which might also reflect a better treatment response, is associated with being male and with milder and less allergic disease. Importantly, whether clinical remission of symptoms equals the disappearance of underlying pathology is unknown. In fact, airway hyper-responsiveness and airway inflammation might remain despite the absence of overt symptoms. Additionally, a new-onset of asthma symptoms is apparent in adulthood, especially in women and in the case of impaired lung function. However, many patients do not remember childhood symptoms, which might reflect relapse rather than true initiation. Both relapse and adult-onset of asthma symptoms have been associated with allergic disease and sensitisation in addition to airway hyper-responsiveness. Thus, asthma symptoms beginning in adults might have originated in childhood. Equivocally, persistence into, relapse, and new-onset of symptoms in adulthood have all been related to active smoking. However, underlying mechanisms for the associations remain unclear, and future asthma research should therefore integrate standardised molecular approaches in identical ways in both paediatric and adult populations and in longitudinal

There have been no reports on the evaluation of the usefulness of long-term asthma management based on the Japanese Pediatric Guideline for the Treatment and Management of Bronchial Asthma 2005 (JPGL 2005). The purpose of the present study was to retrospectively investigate the records of 350 patients admitted to Yamaguchi University Hospital who had asthma attacks from January 2006 to June 2008. There were 149 patients who were treated for more than 3 months in accordance with the guideline (long-term management group) and 201 who were not (non-long-term management group). The patients were divided into three age groups: 100 infants, 159 toddlers, and 91 schoolchildren. The onset age of asthma in the long-term management group was earlier than that in the non-long-term management group in toddlers and schoolchildren. The white blood cell counts and C-reactive protein levels were higher in the non-long-term management group in schoolchildren, suggesting the complication of some infections. The severity of asthma in the long-term management group was greater than that in the non-long-term management group among all three age groups. There were no significant differences, however, in the severity of asthma attack at admission between the long-term and non-long-term management groups in the three age groups. Patients who had severe asthma tended to be treated with long-term management, which suggests that long-term asthma management according to JPGL 2005 may reduce the severity of asthma attack at that admission, because the severity of asthma in patients undergoing long-term management correlates with the severity of asthma attack.
Childhood asthma is a major concern because it leads to more hospital visits and a heavy economic burden. Proper management and prevention strategies for childhood asthma must be based on correct evaluation of prevalence and risk factors for its development. In Korea, nationwide studies were conducted in 1995 and 2000 on students from 68 elementary schools (age, 6-12 years) and junior high schools (age, 12-15 years) by the Korean Academy of Pediatric Allergy and Respiratory Diseases. We used the Korean version of the International Study of Asthma and Allergies in Childhood (ISAAC) written and video questionnaires at the same schools during the same period (October-November). The prevalence of asthma in junior high school children seemed to increase over 5 years. However, in elementary school children, the prevalence of asthma symptoms decreased, although the prevalence of 'diagnosis of asthma, ever' and 'treatment of asthma, last 12 months' increased. In addition, it was found that various factors, such as obesity, passive smoking, dietary habits, raising pets at home, and fever/antibiotic use during infancy were associated with childhood asthma. When prevalence of asthma in Korea was compared with that in different regions, the prevalence changes in the 6-7 years age group did not seem to be consistent between regions, whereas similar trends were observed among children aged 13-14 years. To conduct another epidemiological study to evaluate the time trend over time, a third nationwide survey is planned in 2010, and we anticipate ISAAC Phase 3 will explore recent changes in the prevalence of childhood asthma and assess its risk factors in Korean children. On the basis of accurate data on the current status of childhood asthma in 2010, we will be able to establish proper management strategies.

In urban communities with high prevalence of childhood asthma, school-based educational programs may be the most appropriate approach to deliver interventions to improve asthma morbidity and asthma-related outcomes. The purpose of this study was to evaluate the implementation of Kickin' Asthma, a school-based asthma curriculum designed by health educators and local students, which teaches asthma physiology and asthma self-management techniques to middle and high school students in Oakland, CA. Eligible students were identified through an in-class asthma case identification survey. Approximately 10-15 students identified as asthmatic were recruited for each series of the Kickin' Asthma intervention. The curriculum was delivered by an asthma nurse in a series of four 50-minute sessions. Students completed a baseline and a 3-month follow-up survey that compared symptom frequency, health care utilization, activity limitations, and medication use. Of the 8488 students surveyed during the first 3 years of the intervention (2003-2006), 15.4% (n = 1309) were identified as asthmatic; approximately 76% of eligible students (n = 990) from 15 middle schools and 3 high schools participated in the program. Comparison of baseline to follow-up data indicated that students experienced significantly fewer days with activity limitations and significantly fewer nights of sleep disturbance after participation in the intervention. For health care utilization, students reported significantly less frequent emergency department visits or hospitalizations between the baseline and follow-up surveys. A school-based asthma curriculum designed specifically for urban students has been shown to reduce symptoms, activity limitations, and health care utilization for intervention participants.
Full Text Available Identification and characterization of asthma phenotypes are challenging due to disease complexity and heterogeneity. The Severe Asthma Research Program (SARP used unsupervised cluster analysis to define 5 phenotypically distinct asthma clusters that they replicated using 3 variables in a simplified algorithm. We evaluated whether this simplified SARP algorithm could be used in a separate and diverse urban asthma population to recreate these 5 phenotypic clusters.The SARP simplified algorithm was applied to adults with asthma recruited to the New York University/Bellevue Asthma Registry (NYUBAR to classify patients into five groups. The clinical phenotypes were summarized and compared.Asthma subjects in NYUBAR (n = 471 were predominantly women (70% and Hispanic (57%, which were demographically different from the SARP population. The clinical phenotypes of the five groups generated by the simplified SARP algorithm were distinct across groups and distributed similarly to those described for the SARP population. Groups 1 and 2 (6 and 63%, respectively had predominantly childhood onset atopic asthma. Groups 4 and 5 (20% were older, with the longest duration of asthma, increased symptoms and exacerbations. Group 4 subjects were the most atopic and had the highest peripheral eosinophils. Group 3 (10% had the least atopy, but included older obese women with adult-onset asthma, and increased exacerbations.Application of the simplified SARP algorithm to the NYUBAR yielded groups that were phenotypically distinct and useful to characterize disease heterogeneity. Differences across NYUBAR groups support phenotypic variation and support the use of the simplified SARP algorithm for classification of asthma phenotypes in future prospective studies to investigate treatment and outcome differences between these distinct groups.Clinicaltrials.gov NCT00212537.

Asthma and allergic rhinitis are the two most common chronic disorders in childhood and adolescence. To date, no study has examined the impact of comorbid allergic rhinitis on asthma control in children. To examine the prevalence of allergic rhinitis in children with asthma, and the impact of the disease and its treatment on asthma control. A cross-sectional survey in 203 children with asthma (5-18 years) using validated questionnaires on rhinitis symptoms (stuffy or runny nose outside a cold) and its treatment, and the paediatric Asthma Control Questionnaire (ACQ). Fraction of nitric oxide in exhaled air (FeNO) was measured with a Niox Mino analyser; total and specific IgE levels were assessed by the Immunocap system. 157 children (76.2%) had symptoms of allergic rhinitis but only 88 of these (56.1%) had been diagnosed with the condition by a physician. ACQ scores were worse in children with allergic rhinitis than in those without the condition (p=0.012). An ACQ score ≥ 1.0 (incomplete asthma control) was significantly more likely in children with allergic rhinitis than in those without (OR 2.74, 95% CI 1.28 to 5.91, p=0.0081), also after adjustment for FeNO levels and total serum IgE. After adjustment for nasal corticosteroid therapy, allergic rhinitis was no longer associated with incomplete asthma control (OR 0.72, 95% CI 0.47 to 1.12, p=0.150). Allergic rhinitis is common in children with asthma, and has a major impact on asthma control. The authors hypothesise that recognition and treatment of this condition with nasal corticosteroids may improve asthma control in children, but randomised clinical trials are needed to test this hypothesis.

Asthma is a leading cause of chronic disease-related school absenteeism. Few data exist on how information on absenteeism might be used to identify children for interventions to improve asthma control. This study investigated how asthma-related absenteeism was associated with asthma control, exacerbations, and associated modifiable risk factors using a sample of children from 35 states and the District of Columbia. The Behavioral Risk Factor Surveillance System Child Asthma Call-back Survey is a random-digit dial survey designed to assess the health and experiences of children aged 0-17 years with asthma. During 2014-2015, multivariate analyses were conducted using 2006-2010 data to compare children with and without asthma-related absenteeism with respect to clinical, environmental, and financial measures. These analyses controlled for sociodemographic and clinical characteristics. Compared with children without asthma-related absenteeism, children who missed any school because of asthma were more likely to have not well controlled or very poorly controlled asthma (prevalence ratio=1.50; 95% CI=1.34, 1.69) and visit an emergency department or urgent care center for asthma (prevalence ratio=3.27; 95% CI=2.44, 4.38). Mold in the home and cost as a barrier to asthma-related health care were also significantly associated with asthma-related absenteeism. Missing any school because of asthma is associated with suboptimal asthma control, urgent or emergent asthma-related healthcare utilization, mold in the home, and financial barriers to asthma-related health care. Further understanding of asthma-related absenteeism could establish how to most effectively use absenteeism information as a health status indicator. Published by Elsevier Inc.

Inhalation of cannabis smoke is its most common use and the pulmonary complications of its use may be the single most common form of drug-induced pulmonary disease worldwide. However, the role of cannabis consumption in asthma patients and allergic clinical situations still remains controversial. To review the evidence of asthma and allergic diseases associated with the use of marijuana, we conducted a search of English, Spanish, and Portuguese medical using the search terms asthma, allergy, marijuana, marihuana, and cannabis. Entries made between January 1970 and March 2017 were retrieved. Several papers have shown the relationship between marijuana use and increase in asthma and other allergic diseases symptoms, as well as the increased frequency of medical visits. This narrative review emphasizes the importance to consider cannabis as a precipitating factor for acute asthma and allergic attacks in clinical practice. Although smoking of marijuana may cause respiratory symptoms, there is a need for more studies to elucidate many aspects in allergic asthma patients, especially considering the long-term use of the drug. These patients should avoid using marijuana and be oriented about individual health risks, possible dangers of second-hand smoke exposure, underage use, safe storage, and the over smoking of marijuana.
Full Text Available Asthma is the most common chronic lower respiratory tract disease in childhood throughout the world. Despite advances in asthma management, acute exacerbations continue to be a major problem in patients and they result in a considerable burden on direct/indirect health care providers. A severe exacerbation occurring within 1 year is an independent risk factor. Respiratory tract viruses have emerged as the most frequent triggers of exacerbations in children. It is becoming increasingly clear that interactions may exist between viruses and other triggers, increasing the likelihood of an exacerbation. In this study, we provide an overview of current knowledge about asthma exacerbations, including its definition, impact on health care providers, and associated factors. Prevention management in intermittent asthma as well as intermittent wheeze in pre-school children and those with persistent asthma are discussed. Our review findings support the importance of controlling persistent asthma, as indicated in current guidelines. In addition, we found that early episodic intervention appeared to be crucial in preventing severe attacks and future exacerbations. Besides the use of medication, timely education after an exacerbation along with a comprehensive plan in follow up is also vitally important.
Full Text Available Asthma is characterized by lung inflammation caused by complex interaction between the immune system and environmental factors such as allergens and inorganic pollutants. Recent research in this field is focused on discovering new biomarkers associated with asthma pathogenesis. This review illustrates updated research associating biomarkers of allergic asthma and their potential use in systems biology of the disease. We focus on biomolecules with altered expression, which may serve as inflammatory, diagnostic and therapeutic biomarkers of asthma discovered in human or experimental asthma model using genomic, proteomic and epigenomic approaches for gene and protein expression profiling. These include high-throughput technologies such as state of the art microarray and proteomics Mass Spectrometry (MS platforms. Emerging concepts of molecular interactions and pathways may provide new insights in searching potential clinical biomarkers. We summarized certain pathways with significant linkage to asthma pathophysiology by analyzing the compiled biomarkers. Systems approaches with this data can identify the regulating networks, which will eventually identify the key biomarkers to be used for diagnostics and drug discovery.

Researchers often struggle with the gap between efficacy and effectiveness in clinical research. To bridge this gap, the Community Healthcare for Asthma Management and Prevention of Symptoms (CHAMPS) study adapted an efficacious, randomized controlled trial that resulted in evidence-based asthma interventions in community health centers. Children (aged 5-12 years; N = 590) with moderate to severe asthma were enrolled from 3 intervention and 3 geographically/capacity-matched control sites in high-risk, low-income communities located in Arizona, Michigan, and Puerto Rico. The asthma intervention was tailored to the participant's allergen sensitivity and exposure, and it comprised 4 visits over the course of 1 year. Study visits were documented and monitored prospectively via electronic data capture. Asthma symptoms and health care utilization were evaluated at baseline, and at 6 and 12 months. A total of 314 intervention children and 276 control children were enrolled in the study. Allergen sensitivity testing (96%) and home environmental assessments (89%) were performed on the majority of intervention children. Overall study activity completion (eg, intervention visits, clinical assessments) was 70%. Overall and individual site participant symptom days in the previous 4 weeks were significantly reduced compared with control findings (control, change of -2.28; intervention, change of -3.27; difference, -0.99; P asthma in these high-need populations.

Thoracic surgery poses a risk for complications in the respiratory system. In particular, for patients with bronchial asthma, we need to care for perioperative complications because it is well known that these patients frequently have respiratory complications after surgery, and they may have bronchial spasms during surgery. If we can get good control of their bronchial asthma, we can usually perform surgery for these patients without limitations. For safe postoperative care, it is desirable that these patients have stable asthma conditions that are well-controlled before surgery, as thoracic surgery requires intrabronchial intubation for anesthesia and sometimes bronchial resection. These stimulations to the bronchus do not provide for good conditions because of the risk of bronchial spasm. Therefore, we should use the same agents that are used to control bronchial asthma if it is already well controlled. If it is not, we have to administer a β₂ stimulator, aminophylline, or steroidal agents for good control. Isoflurane or sevoflurane are effective for the safe control of anesthesia during surgery, and we should use a β₂ stimulator, with or without inhalation, or steroidal agents after surgery. It is important to understand that we can perform thoracic surgery for asthma patients if we can provide perioperative control of bronchial asthma, although these patients still have severe risks.

To investigate the links between naturalistically observed conflict, self-reported caregiver-youth conflict, and youth asthma symptoms. Fifty-four youth with asthma (age range: 10-17 years) wore the Electronically Activated Recorder (EAR) for a 4-day period to assess interpersonal conflict and caregiver-youth conflict as they occur in daily life. Conflict also was assessed with baseline self-report questionnaires and daily diaries completed by youth participants and their caregivers. Asthma symptoms were assessed using daily diaries, baseline self-reports, and wheezing, as coded from the EAR. EAR-observed measures of conflict were strongly associated with self-reported asthma symptoms (both baseline and daily diaries) and wheezing coded from the EAR. Further, when entered together in regression analyses, youth daily reports of negative caregiver-youth interactions and EAR-observed conflict uniquely predicted asthma symptoms; only EAR-observed conflict was associated with EAR-observed wheezing. These findings demonstrate the potential impact of daily conflict on youth asthma symptoms and the importance of assessing conflict as it occurs in everyday life. More broadly, they point to the importance of formulating a clear picture of family interactions outside of the lab, which is essential for understanding how family relationships "get under the skin" to affect youth health.

Allergic diseases, including asthma, allergic rhinitis, atopic dermatitis, food allergy, and urticaria are common in general pediatric practice. This review highlights several significant advances in pediatric allergy over the past year, focusing on asthma and atopic dermatitis. With increasing options for the treatment of allergic diseases, much work is now focused on methods for individualizing treatments to a patient's phenotype and genotype. Progress over the past year includes the characterization of effects of regular albuterol use in patients with genetic variations in the beta-adrenergic receptor. Maintenance asthma regimens for children in the first years of life are also an ongoing focus. The relation between upper airway allergic inflammation and asthma has continued to accumulate support and now extends to the middle ear. Environmental influences on asthma and interventions have been described, including environmental controls for asthma and the role of air pollution on lung development in children. Finally, concerns have been raised regarding the use of topical immunomodulators in young children with atopic dermatitis. Progress continues in the care of children with atopic diseases. Attention to treatment with appropriate medications, patient-individualized environmental controls, and extensive education are the keys to successfully treating atopic children. This review highlights several recent advances but is not intended to be a comprehensive review.
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

The aim of our study is to analyse hospital readmissions due to asthma, as well as the factors associated with their increase. We carried out a retrospective study including all admissions of patients over 18 years old due to exacerbation of asthma occurring in our hospital between the years 2000 and 2010. The data were gathered by two members of the research team, by reviewing the clinical records. The first hospital admission of each patient was included for this study. An early readmission (ER) was defined as that which occurred in the following 15 days after hospital discharge and late readmission (LR) to that occurring from 16 days after discharge. This study included 2166 hospital admissions and 1316 patients, with a mean age of 62.6 years. Of the 1316 patients analysed, 36 (2.7%) had one ER and 313 (23.8%) one LR. The only factor independently associated with a higher probability of an ER was poor lung function. A higher probability of LR was associated with a greater severity of the asthma (OR: 17.8, for severe asthma versus intermittent asthma), to have had any hospital admission in the previous year (OR: 3.5) and the use of a combination of ICS-LABA as maintenance treatment. About 25% of the patients in our area admitted to hospital due to asthma exacerbation had repeat episodes of hospitalisation.

Studies from the UK and the USA suggest that frequent use of paracetamol (acetaminophen) may increase the risk of asthma, but data across Europe are lacking.As part of a multi-centre case-control study organised by the GA(2)LEN network we have examined whether frequent paracetamol use is associated...... with adult asthma across Europe. The network compared 521 cases with a diagnosis of asthma and reporting asthma symptoms in the last 12 months with 507 controls with no diagnosis of asthma and no asthmatic symptoms in the last 12 months across 12 European centres. All cases and controls were selected from...... the same population defined by age (20-45 years) and place of residence.In a random effects meta-analysis, after controlling for confounders, the adjusted odds ratio for asthma associated with weekly use of paracetamol, compared with less frequent use, was 2.87 (95% CI: 1.49 to 5.37), P=0...

Although the measurement of fractional exhaled nitric oxide (FE(NO)) has been recommended for observational studies and clinical trials of asthma, FE(NO) has not been examined in studies of childhood asthma in Latin America, To examine the relationship between FE(NO) and indicators of disease control or severity [asthma control test/childhood asthma control test (ACT/C-ACT), lung function, and exercise challenge test (ECT)] in Mexican children with persistent asthma, Children (6-18 years of age) with persistent asthma were consecutively recruited in a tertiary asthma clinic and divided into two groups, e.g. FE(NO) children, Children with FE(NO)children with FE(NO) ≥20 ppb, those with FE(NO) children with persistent asthma, low levels of FE(NO) ( asthma control, and higher lung function.

This study investigates the prevalence of asthma and asthma-related symptoms in New Orleans inner-city schoolchildren. A cross-sectional survey of 1535 elementary, middle, and high school children (aged 5-18) was conducted by using the International Study of Asthma and Allergies in Childhood (ISAAC) written questionnaire. Lifetime prevalence of wheezing was 39.4%, and lifetime prevalence of asthma was 24.4%. Wheezing during the previous 12 months was reported by 25.7% of the sample. Twenty-one percent of respondents reported having one or more attacks of wheezing per year, with 5.6% reporting four or more attacks per year. Many participants reported sleep disturbance (15.4%), with 6.2% reporting sleep disturbance more than once a week. The 12-month rate of speech limitation due to asthma exacerbation was 6.6%. Exercise-induced asthma was reported by 16.9% of the students, and nocturnal cough (not associated with cold) was reported by 27.3%. Overall, boys reported higher rates of symptoms than girls, and younger children (aged 6-7) reported greater symptoms than older children (aged 13-14). These findings show that prevalence of asthma in this population is elevated, and the ISAAC written questionnaire successfully identified inner-city children at risk for asthma in New Orleans.

Background: We examined associations between asthma and sleep in a sample of inner-city adolescents with asthma-like symptoms who are undiagnosed, and to assess the extent to which youth's report of perceived stress moderates this association. Methods: A total of 349 adolescents (83% girls), with a mean age of 15.8 years, and their primary…
