Engagement in physical activity (PA) is one of the important aims of long-term asthma treatment. The objective of this study is to evaluate whether improvement of asthma control is associated with enhanced PA during regular follow-up in children with asthma. Children, 6-18 years, with asthma were eligible for inclusion when their asthma was uncontrolled at a regular follow-up visit. Participants completed a seven-day recall questionnaire to assess engagement in different physical activities (Physical Activity Questionnaires for Children) at baseline and at the time asthma control was achieved according to predefined criteria. They were also instructed to wear an accelerometer (ActigraphTM GT1M) for seven consecutive days at these timepoints. Thirty children (21 boys), aged 10.5 (2.9) years, with uncontrolled asthma were included. After a median (IQR) follow up time of 163 (94-253) days PA was assessed again. Accelerometer obtained moderate vigorous PA (median (IQR) 56 (43-66) versus 53 (35-63) minutes) as well as self-reported PA (median (IQR) PAQ score 7.4 (5.9-10.1) versus 7.2 (6.5-11.0)) were not significantly different at the time of uncontrolled and controlled asthma. Moderate vigorous PA increased in 46.2%, was comparable in 23.1%, and decreased in 30.7% of patients, respectively. Self-reported PA increased in 19.0%, was comparable in 52.4%, and decreased in 28.6% of patients, respectively. Based on the results of this study we conclude that asthma control is not associated with self-reported and accelerometer obtained level of physical activity during regular follow-up in children with asthma.

Background: Oral food challenges (OFCs) are used to confirm or reject a diagnosis of food allergy. However, younger children may encounter difficulties in consuming all offered doses during an OFC in the absence of symptoms, resulting in inconclusive outcomes. Our aim is to assess the eliciting dose for objective symptoms among various age groups and determine the necessity of consuming the final dose step during an uneventful OFC to avoid false negative outcomes., Methods: OFCs for common food allergens performed between 2012 and 2019 were analyzed retrospectively. The primary outcome was the association of age with stop dose for OFCs with inconclusive outcome. Secondary outcome measures were the association of age with eliciting dose and the potential number of false negative outcomes., Results: A total of 1327 OFCs were performed in 707 patients. Of these, 514 (38.7%) were positive, 589 (44.4%) negative, and 224 (16.9%) inconclusive. In OFCs with inconclusive outcome, age appeared to be a significant predictor of the stop dose only for almond (p = .005). Objective symptoms occurred after the last dose step in 2%-13% of all OFCs with positive outcome. In our cohort, potential false negative outcomes may have been drawn in 27.6% of uneventful OFCs., Conclusions: Two third of children under 6 years of age successfully consumed all the provided doses during OFCs with a negative outcome. The eliciting dose for objective symptoms was not associated with age, and in a substantial number of OFCs with positive outcome, symptoms occurred after eating the final dose. These findings suggest that in case of an uneventful OFC, the outcome should be drawn only after a cumulative dose of 4.4 g has been consumed to avoid the risk of a potential false negative outcome., (© 2024 The Authors.

We recently demonstrated that an innovative asthma score independent of auscultation could accurately predict the requirement for bronchodilator nebulization compared to the physician's routine clinical judgment to administer bronchodilators. We aimed to standardize inpatient care for children with acute asthma by implementing a clinical pathway based on this innovative asthma score., Methods: We designed a nurse-driven clinical pathway. This pathway included standardized respiratory assessments and a protocol for the nursing staff to administer bronchodilators without a specific order from the physician. We compared the length of stay and the number of readmissions to a historical cohort., Results: Seventy-nine patients with moderate acute asthma completed the pathway. We obtained a total of 858 Childhood asthma scores in these patients, with a median of 11 scores per patient (interquartile range 8-17). Patients treated according to the nurse-driven protocol were 3.3 times more likely to be discharged earlier (hazard ratio, 3.29; 95% confidence interval, 2.33-4.66; P < 0.05), and length of stay was significantly reduced (median 28 versus 53 h) compared to the historical standard practice. On request, the attending physician assessed the patient's respiratory status 42 times (4.9% of all childhood asthma score assessments). Patient safety was not compromised, and none of the patients were removed from the pathway. In each group, we readmitted two (2.5%) patients within 1 week after discharge., Conclusion: This nurse-driven clinical pathway for children with acute asthma based on an asthma score independent of auscultation findings significantly decreased length of stay without compromising patient safety., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2020 the Author(s).

Background: Failure of milk introduction after a negative food challenge test is reported in a substantial number of patients. For this reason, guidelines recommend that the total dose of milk protein for a food challenge test should be comparable to a normal serving., Objective: Our aim is to compare the success rate of milk introduction after a negative double-blind placebo-controlled challenge test performed with different doses of milk protein and different milk products., Methods: We conducted a retrospective chart review of 485 patients challenged with a low or high dose of milk protein. Pasteurized milk and milk protein powder were used for the low-dose challenge tests, and condensed milk for the high-dose challenge tests. Successful introduction was defined as regular milk consumption, and discontinuation of further introduction due to the reappearance of symptoms as unsuccessful introduction. We also evaluated the association between milk products and successful introduction., Results: The outcome of 288 (59.4%) double-blind placebo-controlled food challenge tests was negative. There were no significant differences between the low and high dose of milk protein in patient characteristics, percentage of patients lost to follow-up (15% vs 20%), in whom introduction had not yet been performed (4% vs 3.1%), reappearance of symptoms (18% vs 17%), and successful introduction (88.0% and 83.4%). Age, gender, specific immunoglobulin E for milk, dose of milk protein, and atopy were not associated with successful introduction. Children who experienced symptoms during the introduction were less likely to consume milk (P < .001). There was a nonsignificant trend toward higher successful introduction rate if pasteurized milk was used as test material compared to milk protein powder, and condensed milk., Conclusion and Clinical Relevance: Successful introduction of milk after a negative challenge test is independent of the total dose of milk protein, and milk product used during the challenge test., (© 2020 The Authors.

Background: Participation in voluntary work may be associated with individual and societal benefits. Because of these benefits and as a result of challenges faced by governments related to population ageing, voluntary work becomes more important for society, and policy measures are aimed at increasing participation rates. In order to effectively identify potential volunteers, insight in the determinants of volunteering is needed. Therefore, we conducted a systematic review including meta-analyses., Methods: A systematic search in MEDLINE, PsycINFO, SocINDEX, Business Source Premier, and EconLit was performed on August 12th 2015. We included longitudinal cohort studies conducted in developed countries that quantified factors associated with volunteering among samples from the general adult population. Two reviewers independently selected eligible studies, extracted the data and assessed the risk of bias of the included studies using the QUIPS tool. Estimates reported in the papers were transformed into Odds Ratios and 95% Confidence Intervals. For each determinant, random-effects meta-analyses were used to generate summary estimates., Results: We found that socioeconomic status, being married, social network size, church attendance and previous volunteer experiences are positively associated with volunteering. Age, functional limitations and transitions into parenthood were found to be inversely related to volunteering., Conclusions: Important key factors have been identified as well as gaps in the current literature. Future research should be directed towards deepening the knowledge on the associations between the factors age, education, income, employment and participation in voluntary work. Moreover, major life course transitions should be studied in relation to volunteering.

Introduction: Diastolic dyssynchrony has correlated with pulmonary capillary wedge pressures in patients with normal cardiac anatomy. No data exist in single right ventricle (sRV) patients. Goal of this study was to determine if diastolic dyssynchrony in sRV patients correlates with ventricular end-diastolic pressures (VEDP)., Methods: Tissue Doppler imaging (TDI) and strain rate (SR) analysis of sRV patients undergoing catheterization were performed. Time interval from onset of QRS to peak TDI e'-wave was obtained. Differences in intervals were calculated: QRS (RV) - QRS (IVS) and QRS (RV) - QRS (LV). Time interval from onset of QRS to peak strain rate early diastolic wave (SRe) was obtained for the 6 segment model sRV. Standard deviation of the 6 SRe time intervals was calculated. Correlation of VEDP with timing intervals was analyzed., Results: Forty sRV patients were evaluated. Age was 2.8 ± 3.5 years. Catheterization VEDP of the sRV was 9.3 ± 3.9 mmHg (median 8 mmHg range 4-24 mmHg). QRS (RV) - QRS (IVS) was 22.3 ± 18.1 msec and QRS (RV) - QRS (LV) was 23.7 ± 19.0 msec. SRe standard deviation of the sRV was 61.6 ± 23.9 msec. There was no significant correlation with VEDP and QRS (RV) - QRS (IVS) (r = 0.1, P = NS) or with QRS (RV) - QRS (LV) (r = 0.2, P = NS). There was a significant correlation of VEDP with the SRe standard deviation value (r = 0.4, P < 0.05)., Conclusion: Diastolic dyssynchrony correlated with VEDP in patients with sRV physiology. Future studies are needed to determine the significance of these findings., (© 2013, Wiley Periodicals, Inc.)
