TL;DR: Mild to moderate asthma has imposed modest effects on the daily life but not the psychological health of this group of children, and variation in the psychological characteristics of these children was traceable to the overall psychological adaptation of their families.
Abstract: Objective To test the hypotheses that the burden of childhood asthma compromises psychological adaptation and that the degree of compromise increases with disease severity. Design The Childhood Asthma Management Program (CAMP) is a multicenter randomized clinical trial initiated and funded by the National Heart, Lung, and Blood Institute. Setting Study sites were located in Albuquerque, NM, Baltimore, Md, Boston, Mass, Denver, Colo, St Louis, Mo, San Diego, Calif, Seattle, Wash, and Toronto, Ontario. Participants A total of 1041 children aged 5 to 12 years were randomized to the trial after confirming their mild to moderate asthma. Main Outcome Measures Psychological questionnaires administered at baseline to parents and participants assessed anxiety, depression, behavioral competence, social support, and family functioning. Results Psychological difficulty was not increased in this group of asthmatic children and their families. Psychological adaptation in the children was associated with the psychological adaptation of the family but not with disease-related variables. Scores from the Impact on Family Scale, a measure of family quality of life related to the child's illness, were associated more strongly with the overall psychological characteristics of the family and child and very little with disease characteristics or severity. Conclusions Mild to moderate asthma has imposed modest effects on the daily life but not the psychological health of this group of children. Variation in the psychological characteristics of these children was, as is the case for most children, traceable to the overall psychological adaptation of their families.

TL;DR: Thirty-two single-nucleotide polymorphisms (SNPs) in or near 17 genes in 11 previously identified GWS spirometric genomic regions were tested for association with COPD status in data from four COPD case-control studies, and three loci showed evidence of association with CopD susceptibility at a 5% false discovery rate.
Abstract: Two recent metaanalyses of genome-wide association studies conducted by the CHARGE and SpiroMeta consortia identified novel loci yielding evidence of association at or near genome-wide significance (GWS) with FEV1 and FEV1/FVC. We hypothesized that a subset of these markers would also be associated with chronic obstructive pulmonary disease (COPD) susceptibility. Thirty-two single-nucleotide polymorphisms (SNPs) in or near 17 genes in 11 previously identified GWS spirometric genomic regions were tested for association with COPD status in four COPD case-control study samples (NETT/NAS, the Norway case-control study, ECLIPSE, and the first 1,000 subjects in COPDGene; total sample size, 3,456 cases and 1,906 controls). In addition to testing the 32 spirometric GWS SNPs, we tested a dense panel of imputed HapMap2 SNP markers from the 17 genes located near the 32 GWS SNPs and in a set of 21 well studied COPD candidate genes. Of the previously identified GWS spirometric genomic regions, three loci harbored SNPs...

TL;DR: A functional role for Syk is delineated in the development of mast cell- and IgE-mediated AHR and airway inflammation, and these results indicate that inhibition of Syk may be a target in the treatment of allergic asthma.
Abstract: Rationale: Spleen tyrosine kinase (Syk) is important for Fc and B-cell receptor–mediated signaling.Objective: To determine the activity of a specific Syk inhibitor (R406) on mast cell activation in vitro and on the development of allergen-induced airway hyperresponsiveness (AHR) and inflammation in vivo.Methods: AHR and inflammation were induced after 10 d of allergen (ovalbumin [OVA]) exposure exclusively via the airways and in the absence of adjuvant. This approach was previously established to be IgE, FceRI, and mast cell dependent. Alternatively, mice were passively sensitized with OVA-specific IgE, followed by limited airway challenge. In vitro, the inhibitor was added to cultures of IgE-sensitized bone marrow–derived mast cells (BMMCs) before cross-linking with allergen.Results: The inhibitor prevented OVA-induced degranulation of passively IgE-sensitized murine BMMCs and inhibited the production of interleukin (IL)-13, tumor necrosis factor α, IL-2, and IL-6 in these sensitized BMMCs. When administ...

TL;DR: LVRS reduces the frequency of COPD exacerbations and increases the time to first exacerbation and one explanation may be the postoperative improvement in lung function.
Abstract: Rationale: Lung volume reduction surgery (LVRS) has been demonstrated to provide a functional and mortality benefit to a select group of subjects with chronic obstructive pulmonary disease (COPD). The effect of LVRS on COPD exacerbations has not been as extensively studied, and whether improvement in postoperative lung function alters the risk of disease exacerbations is not known. Objectives: To examine the effect, and mechanism of potential benefit, of LVRS on COPD exacerbations by comparing the medical and surgical cohorts of the National Emphysema Treatment Trial (NETT). Methods: A COPD exacerbation was defined using Centers for Medicare and Medicaid Services data and International Classification of Diseases, Ninth Revision, discharge diagnosis. Measurements and Main Results: There was no difference in exacerbation rate or time to first exacerbation between the medical and surgical cohorts during the year before study randomization (P = 0.58 and 0.85, respectively). Postrandomization, the surgical cohort experienced an approximate 30% reduction in exacerbation frequency (P = 0.0005). This effect was greatest in those subjects with the largest postoperative improvement in FEV1 (P = 0.04) when controlling for changes in other spirometric measures of lung function, lung capacities, and room air arterial blood gas tensions. Finally, LVRS increased the time to first exacerbation in both those subjects with and those without a prior history of exacerbations (P = 0.0002 and P < 0.0001, respectively). Conclusions: LVRS reduces the frequency of COPD exacerbations and increases the time to first exacerbation. One explanation for this benefit may be the postoperative improvement in lung function. Clinical trial registered with www.clinicaltrials.gov (NCT 00000606).

TL;DR: The activation of MAPKs may play a role in Fc gammaR signal transduction, and the activation of p42MAPK is necessary for Fc Gamma R cross-linking-induced TNF-alpha synthesis is suggested.
Abstract: Fc gamma R cross-linking on murine macrophages resulted in the activation of mitogen-activated protein kinase (MAPK) family members p42MAPK, p38, and c-Jun NH2-terminal kinase (JNK)/stress-activated protein kinase (SAPK). The temporal pattern of activation was distinct for each kinase. p42MAPK activation peaked at 5 min after receptor cross-linking, while peak p38 activity occurred 5 to 10 min later. Maximal JNK/SAPK activation occurred 20 min after Fc gamma R cross-linking. The selective MAPK/extracellular signal-regulated kinase-1 (MEK-1) inhibitor PD 098059 inhibited activation of p42MAPK induced by Fc gamma R cross-linking, but not p38 or JNK/SAPK activation. PD 098059 also inhibited the synthesis of TNF-alpha induced by Fc gamma R cross-linking (IC50 approximately 0.1 microM). Together, these results suggest that 1) the activation of MAPKs may play a role in Fc gammaR signal transduction, and 2) the activation of p42MAPK is necessary for Fc gamma R cross-linking-induced TNF-alpha synthesis.
