Current cystic fibrosis (CF) treatment strategies are primarily focused on oral/inhaled anti-inflammatories and antibiotics, resulting in a considerable treatment burden for CF patients. Therefore, combination treatments consisting of anti-inflammatories with antibiotics could reduce the CF treatment burden. However, there is an imperative need to understand the potential drug-drug interactions of these combination treatments to determine their efficacy. Thus, this study aimed to determine the interactions of the anti-inflammatory agent Ibuprofen with each of the CF-approved inhaled antibiotics (Tobramycin, Colistin and its prodrug colistimethate sodium/Tadim) and anti-bacterial and anti-inflammatory efficacy. Chemical interactions of the Ibuprofen:antibiotic combinations were elucidated using High-Resolution Mass-Spectrometry (HRMS) and 1H NMR. HRMS showed pairing of Ibuprofen and Tobramycin, further confirmed by 1H NMR whilst no pairing was observed for either Ibuprofen:Colistin or Ibuprofen:Tadim combinations. The anti-bacterial activity of the combinations against Pseudomonas aeruginosa showed that neither paired nor non-paired Ibuprofen:antibiotic therapies altered the anti-bacterial activity. The anti-inflammatory efficacy of the combination therapies was next determined at two different concentrations (Low and High) using in vitro models of NuLi-1 (healthy) and CuFi-1 (CF) cell lines. Differential response in the anti-inflammatory efficacy of Ibuprofen:Tobramycin combination was observed between the two concentrations due to changes in the structural conformation of the paired Ibuprofen:Tobramycin complex at High concentration, confirmed by 1H NMR. In contrast, the non-pairing of the Ibuprofen:Colistin and Ibuprofen:Tadim combinations showed a significant decrease in IL-8 secretion at both the concentrations. Importantly, all antibiotics alone showed anti-inflammatory properties, highlighting the inherent anti-inflammatory properties of these antibiotics.

1107 Immunology, 1115 Pharmacology and Pharmaceutical Sciences - Abstract
Objective: Offspring born to mothers with asthma in pregnancy are known to have lower lung function which tracks with age. Human group 2 innate lymphoid cells (ILC2) accumulate in foetal lungs, at 10-fold higher levels compared to adult lungs. However, there are no data on foetal ILC2 numbers and the association with respiratory health outcomes such as lung function in early life. We aimed to investigate cord blood immune cell populations from babies born to mothers with asthma in pregnancy. Methods: Cord blood from babies born to asthmatic mothers was collected, and cells were stained in whole cord blood. Analyses were done using traditional gating approaches and computational methodologies (t-distributed stochastic neighbour embedding and PhenoGraph algorithms). At 6 weeks of age, the time to peak tidal expiratory flow as a percentage of total expiratory flow time (tPTEF/tE%) was determined as well as Lung Clearance Index (LCI), during quiet natural sleep. Results: Of 110 eligible infants (March 2017 to November 2019), 91 were successfully immunophenotyped (82.7%). Lung function was attempted in 61 infants (67.0%), and 43 of those infants (70.5% of attempted) had technically acceptable tPTEF/tE% measurements. Thirty-four infants (55.7% of attempted) had acceptable LCI measurements. Foetal ILC2 numbers with increased expression of chemoattractant receptor-homologous molecule (CRTh2), characterised by two distinct analysis methodologies, were associated with poorer infant lung function at 6 weeks of age." Conclusion: Foetal immune responses may be a surrogate variable for or directly influence lung function outcomes in early life.

© 2017 the American Physiological Society. The forced oscillation technique (FOT) can provide unique and clinically relevant lung function information with little cooperation with subjects. However, FOT has higher variability than spirometry, possibly because strategies for quality control and reducing artifacts in FOT measurements have yet to be standardized or validated. Many quality control procedures rely on either simple statistical filters or subjective evaluation by a human operator. In this study, we propose an automated artifact removal approach based on the resistance against flow profile, applied to complete breaths. We report results obtained from data recorded from children and adults, with and without asthma. Our proposed method has 76% agreement with a human operator for the adult data set and 79% for the pediatric data set. Furthermore, we assessed the variability of respiratory resistance measured by FOT using within-session variation (wCV) and between-session variation (bCV). In the asthmatic adults test data set, our method was again similar to that of the manual operator for wCV (6.5 vs. 6.9%) and significantly improved bCV (8.2 vs. 8.9%). Our combined automated breath removal approach based on advanced feature extraction offers better or equivalent quality control of FOT measurements compared with an expert operator and computationally more intensive methods in terms of accuracy and reducing intrasubject variability. NEW &NOTEWORTHY The forced oscillation technique (FOT) is gaining wider acceptance for clinical testing; however, strategies for quality control are still highly variable and require a high level of subjectivity. We propose an automated, complete breath approach for removal of respiratory artifacts from FOT measurements, using feature extraction and an interquartile range filter. Our approach offers better or equivalent performance compared with an expert operator, in terms of accuracy and reducing intrasubject variability.

BACKGROUND The safe and appropriate use of long-acting beta-agonists (LABAs) for the treatment of asthma has been widely debated. In two large clinical trials, investigators found a potential risk of serious asthma-related events associated with LABAs. This study was designed to evaluate the risk of administering the LABA salmeterol in combination with an inhaled glucocorticoid, fluticasone propionate. METHODS In this multicenter, randomized, double-blind trial, adolescent and adult patients (age, ≥12 years) with persistent asthma were assigned to receive either fluticasone with salmeterol or fluticasone alone for 26 weeks. All the patients had a history of a severe asthma exacerbation in the year before randomization but not during the previous month. Patients were excluded from the trial if they had a history of lifethreatening or unstable asthma. The primary safety end point was the first serious asthma-related event (death, endotracheal intubation, or hospitalization). Noninferiority of fluticasone–salmeterol to fluticasone alone was defined as an upper boundary of the 95% confidence interval for the risk of the primary safety end point of less than 2.0. The efficacy end point was the first severe asthma exacerbation. RESULTS Of 11,679 patients who were enrolled, 67 had 74 serious asthma-related events, with 36 events in 34 patients in the fluticasone–salmeterol group and 38 events in 33 patients in the fluticasone-only group. The hazard ratio for a serious asthmarelated event in the fluticasone–salmeterol group was 1.03 (95% confidence interval [CI], 0.64 to 1.66), and noninferiority was achieved (P = 0.003). There were no asthma-related deaths; 2 patients in the fluticasone-only group underwent asthmarelated intubation. The risk of a severe asthma exacerbation was 21% lower in the fluticasone–salmeterol group than in the fluticasone-only group (hazard ratio, 0.79; 95% CI, 0.70 to 0.89), with at least one severe asthma exacerbation occurring in 480 of 5834 patients (8%) in the fluticasone–salmeterol group, as compared with 597 of 5845 patients (10%) in the fluticasone-only group (P

Radiation injury claims may arise under various legal theories. In addition, plaintiffs may advance such claims within different jurisdictional venues, such as federal and state courts and workers' compensation boards. Irrespective of the jurisdiction or the legal theory underlying the claim, one element remains common to these claims--the quality and quantity of the evidence. While many different pieces of evidence may be needed to litigate a radiation injury claim, the most important evidence for the investigating health physicist is that which establishes the nature and extent of radiation exposure. Most radiation injury claims are associated with late radiation injury, often an allegation of radiation-induced cancer. Because radiation-induced cancers have a long latency period, claims may not arise for years, or even decades, after exposure. Therefore, the immediate challenge to the health physicist, who investigates an exposure, is to avoid the temptation of a "wait and see" approach to gathering evidence. Not only may evidence be short-lived in nature, but with the passage of time memories grow dim and witnesses may become unavailable. Prompt and thorough gathering of pertinent evidence likely will be a determining factor in the outcome of any radiation injury claim. Although ensuring the availability of all pertinent evidence is the key role of the investigating health physicist, he or she also can help to ensure that the evidence does not inadvertently become inadmissible in a court of law, for example, under the hearsay rule. To ensure that the necessary evidence is available in admissible form, the task of gathering evidence should be systematically approached using a pre-established process that reflects a basic understanding of the rules of evidence. Such a process is discussed here.

- Abstract
AIM: To define the demographics and clinical characteristics of cases presenting with nutritional rickets to paediatric centres in Sydney, Australia. METHODS: Retrospective descriptive study of 126 cases seen from 1993 to 2003 with a diagnosis of vitamin D deficiency and/or confirmed rickets defined by long bone x ray changes. RESULTS: A steady increase was seen in the number of cases per year, with a doubling of cases from 2002 to 2003. Median age of presentation was 15.1 months, with 25% presenting at less than 6 months of age. The most common presenting features were hypocalcaemic seizures (33%) and bowed legs (22%). Males presented at a younger age, with a lower weight SDS, and more often with seizures. The caseload was almost exclusively from recently immigrated children or first generation offspring of immigrant parents, with the region of origin predominantly the Indian subcontinent (37%), Africa (33%), and the Middle East (11%). Seventy nine per cent of the cases were born in Australia. Eleven cases (all aged <7 months) presented atypically with hyperphosphataemia. CONCLUSIONS: This large case series shows that a significant and increasing caseload of vitamin D deficiency remains, even in a developed country with high sunlight hours. Cases mirror recent immigration trends. Since birth or residence in Australia does not appear to be protective, screening of at risk immigrant families should be implemented through public health policies. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Tai Chi Chuan (TTC) exercise has beneficial effects on the components of physical condition and can produce a substantial reduction in the risk of multiple falls. Previous studies have shown that short term TCC exercise did not improve the scores in the single leg stance test with eyes closed and the sit and reach test. There has apparently been no research into the effects of TCC on total body rotation flexibility and heart rate responses at rest and after a three minute step test.Methods: In this cross sectional study, 28 male TCC practitioners with an average age of 67.5 years old and 13.2 years of TCC exercise experience were recruited to form the TCC group. Another 30 sedentary men aged 66.2 were selected to serve as the control group. Measurements included resting heart rate, left and right single leg stance with eyes closed, modified sit and reach test, total body rotation test (left and right), and a three minute step test.Results: Compared with the sedentary group, the TCC group had significantly better scores in resting heart rate, three minute step test heart rate, modified sit and reach, total body rotation test on both right and left side (p < 0.01), and both right and left leg standing with eyes closed (p < 0.05). According to the American Fitness Standards, the TCC group attained the 90th percentile rank for sit and reach and total body rotation test, right and left.Conclusion: Long term regular TCC exercise has favourable effects on the promotion of balance control, flexibility, and cardiovascular fitness in older adults.

- Abstract
Background: This study aimed to determine the proportion of patients receiving clinical practice guideline (CPG)-inconsistent care related to chemotherapy-induced vomiting (CIV) prophylaxis, and to describe the association between CPG-inconsistent care and site size. The association between delivery of CPG-inconsistent care and patient outcomes (CIV control, admission prolongation, and unplanned healthcare visits) was also described., Methods: This was a retrospective study conducted at Children's Oncology Group (COG) National Cancer Institute Community Oncology Research Program (NCORP) sites. Eligible patients received highly (HEC) or moderately emetogenic chemotherapy (MEC) as inpatients from January 2014 through December 2015, and were previously enrolled in a COG study. The COG generated a patient list from which patients were randomly selected for chart review by participating sites. A central panel adjudicated CIV prophylaxis received as CPG-consistent or -inconsistent., Results: Twenty-four sites participated. Over half of patients received CPG-inconsistent CIV prophylaxis (HEC: 59/112, 52.6%; MEC: 119/215, 55.3%). The most common reasons for CPG-inconsistency were shortened duration of antiemetic administration or omission of dexamethasone. Site size was not found to be associated with CPG-inconsistent care delivery (HEC: adjusted odds ratio [OR]: 0.96, 95% confidence interval [CI]: 0.76-1.23; MEC: adjusted OR: 1.07; 95% CI: 0.92-1.24). Additionally, there was no statistically significant association between receipt of CPG-inconsistent care and patient outcomes., Conclusions: Patients receiving MEC or HEC often received CPG-inconsistent CIV prophylaxis. Site size was not associated with receipt of CPG-inconsistent care. Future studies should evaluate strategies to improve CIV control among pediatric oncology patients including those aimed at improving CPG adherence., (© 2024 The Author(s).

- Abstract
Background: Many children undergo allogeneic hematopoietic stem cell transplantation (HSCT) for the treatment of malignant and nonmalignant conditions. Unfortunately, pulmonary complications occur frequently post-HSCT, with bronchiolitis obliterans syndrome (BOS) being the most common noninfectious pulmonary complication. Current international guidelines contain conflicting recommendations regarding post-HSCT surveillance for BOS, and a recent NIH workshop highlighted the need for a standardized approach to post-HSCT monitoring. As such, this guideline provides an evidence-based approach to detection of post-HSCT BOS in children. Methods: A multinational, multidisciplinary panel of experts identified six questions regarding surveillance for, and evaluation of, post-HSCT BOS in children. A systematic review of the literature was undertaken to answer each question. The Grading of Recommendations, Assessment, Development, and Evaluation approach was used to rate the quality of evidence and the strength of recommendations. Results: The panel members considered the strength of each recommendation and evaluated the benefits and risks of applying the intervention. In formulating the recommendations, the panel considered patient and caregiver values, the cost of care, and feasibility. Recommendations addressing the role of screening pulmonary function testing and diagnostic tests in children with suspected post-HSCT BOS were made. Following a Delphi process, new diagnostic criteria for pediatric post-HSCT BOS were also proposed. Conclusions: This document provides an evidence-based approach to the detection of post-HSCT BOS in children while also highlighting considerations for the implementation of each recommendation. Further, the document describes important areas for future research.

- Abstract
Hematopoietic stem cell transplantation (HSCT) is undertaken in children with the aim of curing a range of malignant and nonmalignant conditions. Unfortunately, pulmonary complications, especially bronchiolitis obliterans syndrome (BOS), are significant sources of morbidity and mortality post-HSCT. Currently, criteria developed by a National Institutes of Health (NIH) working group are used to diagnose BOS in children post-HSCT. Unfortunately, during the development of a recent American Thoracic Society (ATS) Clinical Practice Guideline on this topic, it became apparent that the NIH criteria have significant limitations in the pediatric population, leading to late diagnosis of BOS. Specific limitations include use of an outdated pulmonary function testing reference equation, a reliance on spirometry, use of a fixed forced expiratory volume in 1 second (FEV
1 ) threshold, focus on obstructive defects defined by FEV1 /vital capacity, and failure to acknowledge that BOS and infection can coexist. In this review, we summarize the evidence regarding the limitations of the current criteria. We also suggest potential evidence-based ideas for improving these criteria. Finally, we highlight a new proposed criteria for post-HSCT BOS in children that were developed by the authors of the recently published ATS clinical practice guideline, along with a pathway forward for improving timely diagnosis of BOS in children post-HSCT., (Copyright © 2024 The American Society for Transplantation and Cellular Therapy.

- Abstract
Background: Effective detection of early lung disease in cystic fibrosis (CF) is critical to understanding early pathogenesis and evaluating early intervention strategies. We aimed to compare ability of several proposed sensitive functional tools to detect early CF lung disease as defined by CT structural disease in school aged children., Methods: 50 CF subjects (mean±SD 11.2 ± 3.5y, range 5-18y) with early lung disease (FEV
1 ≥70 % predicted: 95.7 ± 11.8 %) performed spirometry, Multiple breath washout (MBW, including trapped gas assessment), oscillometry, cardiopulmonary exercise testing (CPET) and simultaneous spirometer-directed low-dose CT imaging. CT data were analysed using well-evaluated fully quantitative software for bronchiectasis and air trapping (AT)., Results: CT bronchiectasis and AT occurred in 24 % and 58 % of patients, respectively. Of the functional tools, MBW detected the highest rates of abnormality: Scond 82 %, MBWTG RV 78 %, LCI 74 %, MBWTG IC 68 % and Sacin 51 %. CPET VO2 peak detected slightly higher rates of abnormality (9 %) than spirometry-based FEV1 (2 %). For oscillometry AX (14 %) performed better than Rrs (2 %) whereas Xrs and R5-19 failed to detect any abnormality. LCI and Scond correlated with bronchiectasis (r = 0.55-0.64, p < 0.001) and AT (r = 0.73-0.74, p < 0.001). MBW-assessed trapped gas was detectable in 92 % of subjects and concordant with CT-assessed AT in 74 %., Conclusions: Significant structural and functional deficits occur in early CF lung disease, as detected by CT and MBW. For MBW, additional utility, beyond that offered by LCI, was suggested for Scond and MBW-assessed gas trapping. Our study reinforces the complementary nature of these tools and the limited utility of conventional oscillometry and CPET in this setting., Competing Interests: Declaration of competing interest The authors have no conflict of interests to declare, (Copyright © 2024 The Author(s).

- Abstract
Background: Several techniques can be used to assess bronchodilator response (BDR) in preschool-aged children, including spirometry, respiratory oscillometry, the interrupter technique, and specific airway resistance. However, there has not been a systematic comparison of BDR thresholds across studies yet., Methods: A systematic review was performed on all studies up to May 2023 measuring a bronchodilator effect in children 2-6 years old using one of these techniques (PROSPERO CRD42021264659). Studies were identified using MEDLINE, Cochrane, EMBASE, CINAHL via EBSCO, Web of Science databases, and reference lists of relevant manuscripts., Results: Of 1224 screened studies, 43 were included. Over 85% were from predominantly European ancestry populations, and only 22 studies (51.2%) calculated a BDR cutoff based on a healthy control group. Five studies included triplicate testing with a placebo to account for the within-subject intrasession repeatability. A relative BDR was most consistently reported by the included studies (95%) but varied widely across all techniques. Various statistical methods were used to define a BDR, with six studies using receiver operating characteristic analyses to measure the discriminative power to distinguish healthy from wheezy and asthmatic children., Conclusion: A BDR in 2- to 6-year-olds cannot be universally defined based on the reviewed literature due to inconsistent methodology and cutoff calculations. Further studies incorporating robust methods using either distribution-based or clinical anchor-based approaches to define BDR are required., (© 2024 The Author(s).

- Abstract
Purpose: This study describes chemotherapy-induced nausea and vomiting (CINV) control rates in pediatric and adult patients who did or did not receive guideline-consistent CINV prophylaxis., Methods: We conducted a systematic literature review of studies published in 2000 or later that evaluated CINV control in patients receiving guideline-consistent vs. guideline-inconsistent CINV prophylaxis and reported at least one CINV-related patient outcome. Studies were excluded if the guideline evaluated was not publicly available or not developed by a professional organization. Over-prophylaxis was defined as antiemetic use recommended for a higher level of chemotherapy emetogenicity than a patient was receiving., Results: We identified 7060 citations and retrieved 141 publications for full-text evaluation. Of these, 21 publications (14 prospective and seven retrospective studies) evaluating guidelines developed by six organizations were included. The terms used to describe CINV endpoints and definition of guideline-consistent CINV prophylaxis varied among studies. Included studies either did not address over-prophylaxis in their definition of guideline-consistent CINV prophylaxis (48%; 10/21) or defined it as guideline-inconsistent (38%; 8/21) or guideline-consistent (3/21; 14%). Eleven included studies (52%; 11/21) reported a clinically meaningful improvement in at least one CINV endpoint in patients receiving guideline-consistent CINV prophylaxis. Ten reported a statistically significant improvement., Conclusions: This evidence supports the use of guideline-consistent prophylaxis to optimize CINV control. Institutions caring for patients with cancer should systematically adapt CINV CPGs for local implementation and routinely evaluate CINV outcomes., (© 2024.

- Abstract
Purpose: The Pediatric Oncology Group of Ontario (POGO) supported an effort to implement infection management care pathways based on clinical practice guidelines, to improve the consistency of infection management in pediatric cancer patients. The objective of this qualitative study was to describe the perspective of healthcare professionals (HCPs) following implementation., Methods: Four tertiary pediatric oncology centers in Ontario, Canada, implemented the pathways. We randomly identified three HCPs per group (clinical pharmacists; nurse case managers, educators or practitioners and physician assistants; pediatric oncology fellows; or pediatric oncology staff physicians) per site and invited them to participate in a qualitative interview. One-on-one interviews were conducted remotely, followed by thematic analysis of interview transcripts., Results: A total of 66 invitations were extended and 42 HCPs participated. Identified themes were: (1) implementation approach, (2) access and navigation, (3) engagement, (4) concerns, (5) workplace benefits, (6) reception, and (7) provincial harmonization. HCPs preferred in-person implementation strategies over e-mail communication. They identified teaching/educational utility and benefits to non-oncology departments and non-tertiary centers participating in shared care of patients. Other positive aspects related to evidence-based practice, safety, supporting oncology HCPs, and benefits to patients and families. Concerns included need to ensure users applied clinical judgement and loss of autonomy. Provincial harmonization of practice was viewed positively, although potential logistical and institutional cultural barriers were raised., Conclusions: Following infection management care pathway implementation, HCPs described educational utility and benefits to non-oncology departments, oncology HCPs, patients, and families. Our findings may facilitate future infection management care pathway provincial harmonization., (© 2024.

- Abstract
Background: Fetal exposure to tobacco smoking throughout pregnancy is associated with wheezing in infancy. We investigated the influence of in utero smoking exposure on lung ventilation homogeneity and the relationship between lung ventilation inhomogeneity at 7 weeks of age and wheezing in the first year of life., Methods: Maternal smoking was defined as self-reported smoking of tobacco or validated by exhaled (e)CO > 6 ppm. Lung function data from healthy infants (age 5-9 weeks) born to asthmatic mothers and parent-reported respiratory questionnaire data aged 12 months were collected in the Breathing for Life Trial (BLT) birth cohort. Tidal breathing analysis and SF
6 -based Multiple Breath Washout testing were performed in quiet sleep. Descriptive statistics and regression analysis were used to assess associations., Results: Data were collected on 423 participants. Infants born to women who self-reported smoking during pregnancy (n = 42) had higher lung clearance index (LCI) than those born to nonsmoking mothers (7.90 vs. 7.64; p = .030). Adjusted regression analyzes revealed interactions between self-reported smoking and LCI (RR: 1.98, 95% CI: 1.07-3.63, 0.028, for each unit increase in LCI) and between eCO > 6 ppm and LCI (RR: 2.25, 95% CI: 1.13-4.50, 0.022) for the risk of wheeze in the first year of life., Conclusion: In utero tobacco smoke exposure induces lung ventilation inhomogeneities. Furthermore, an interaction between smoke exposure and lung ventilation inhomogeneities increases the risk of having a wheeze in the first year of life., (© 2024 The Authors.

Kjellberg S, Olin AC, Schiöler L, and Robinson PD
- Abstract
Background: Small airway dysfunction (SAD) is increasingly recognized as an important feature of pediatric asthma yet typically relies on spirometry-derived FEF
25-75 to detect its presence. Multiple breath washout (MBW) and oscillometry potentially offer improved sensitivity for SAD detection, but their utility in comparison to FEF25-75 , and correlations with clinical outcomes remains unclear for school-age asthma. We investigated SAD occurrence using these techniques, between-test correlation and links to clinical outcomes in 57 asthmatic children aged 8-18 years., Methods: MBW and spirometry abnormality were defined as z -scores above/below ± 1.96, generating MBW reference equations from contemporaneous controls ( n = 69). Abnormal oscillometry was defined as > 97.5th percentile, also from contemporaneous controls ( n = 146). Individuals with abnormal FEF25-75 , MBW, or oscillometry were considered to have SAD., Results: Using these limits of normal, SAD was present on oscillometry in 63% (resistance at 5-20 Hz; R5-R20; >97.5th percentile), on MBW in 54% (Scond ; z -scores> +1.96) and in spirometry FEF25-75 in 44% of participants ( z -scores< -1.96). SAD, defined by oscillometry and/or MBW abnormality, occurred in 77%. Among those with abnormal R5-R20, Scond was abnormal in 71%. Correlations indicated both R5-R20 and Scond were linked to asthma medication burden, baseline FEV1 and reversibility. Additionally, Scond correlated with FE NO and magnitude of bronchial hyper-responsiveness. SAD, detected by oscillometry and/or MBW, occurred in almost 80% of school-aged asthmatic children, surpassing FEF25-75 detection rates., Conclusions: Discordant oscillometry and MBW abnormality suggests they reflect different aspects of SAD, serving as complementary tools. Key asthma clinical features, like reversibility, had stronger correlation with MBW-derived Scond than oscillometry-derived R5-R20.- Published

- Abstract
Background: The primary objective was to measure adherence to clinical practice guideline (CPG) recommendations for fertility preservation (FP) in pediatric cancer patients treated in National Cancer Institute Community Oncology Research Program (NCORP) sites. Secondary objectives were to describe factors such as site size associated with CPG-inconsistent care delivery and cryopreservation completion. Methods: This retrospective, multicenter study included patients 15 to 21 years old with a first cancer diagnosis from January 2014 through December 2015 who were previously enrolled to a Children's Oncology Group (COG) study and received care at a participating NCORP site. Patients were randomly selected from a list generated by the COG for chart review by participating sites. Primary outcome was care delivery that was inconsistent with a strong CPG recommendation on FP, namely discussion and offering of FP options before cancer treatment initiation, as adjudicated centrally by a panel. Results: A total of 129 patients from 25 sites were included. Among these, 48% (62/129) received CPG-inconsistent care. Most CPG-inconsistent care was due to lack of FP discussion documentation (93.5%, 58/62). Small site size, treatment at a pediatric (vs mixed adult/pediatric) site, and female sex were associated with higher odds of CPG-inconsistent care delivery. Conclusions: Newly diagnosed pediatric cancer patients often received CPG-inconsistent care for FP, with disproportionate gaps noted for females, and those treated at smaller or pediatric NCORP sites. The primary reason for CPG-inconsistent care is lack of FP discussion from clinicians. Opportunities to improve FP CPG implementation are highlighted.

- Abstract
Our objective was to update a clinical practice guideline for the prevention and treatment of Clostridioides difficile infection (CDI) in pediatric patients with cancer and hematopoietic cell transplantation recipients. We reconvened an international multi-disciplinary panel. A systematic review of randomized controlled trials (RCTs) for the prevention or treatment of CDI in any population was updated and identified 31 new RCTs. Strong recommendations were made to use either oral metronidazole or oral vancomycin for non-severe CDI treatment, and to use either oral vancomycin or oral fidaxomicin for severe CDI. A strong recommendation that fecal microbiota transplantation should not be routinely used to treat CDI was also made. The panel made two new good practice statements to follow infection control practices including isolation in patients experiencing CDI, and to minimize systemic antibacterial administration where feasible, especially in patients who have experienced CDI., Competing Interests: BTF has served on a data safety monitoring board for Astellas and BTF's institution has received grant support from Allovir and Pfizer as well as CDC, FDA and NIH for research performed.

- Abstract
Background: The primary objective was to measure the proportion of episodes where care delivery was inconsistent with selected recommendations of a clinical practice guideline (CPG) on fever and neutropenia (FN) management. The influence of site size on CPG-inconsistent care delivery, and association between patient outcomes and CPG-inconsistent care were described., Methods: This retrospective, multicenter study included patients less than 21 years old with cancer who were at high risk of poor FN outcomes and were previously enrolled to a Children's Oncology Group (COG) study at participating National Cancer Institute Community Oncology Research Program (NCORP) institutions from January 2014 through December 2015. Patients were randomly selected for chart review by participating sites from a COG-generated list. Care delivered in each episode was adjudicated (CPG-consistent or CPG-inconsistent) against each of five selected recommendations., Results: A total of 107 patients from 22 sites, representing 157 FN episodes, were included. The most common CPG-inconsistent care delivered was omission of pulmonary computerized tomography in patients with persistent FN (60.3%). Of 74 episodes where assessment of four (episodes without persistent FN) or five (episodes with persistent FN) recommendations was possible, CPG-inconsistent care was delivered with respect to at least one recommendation in 63 (85%) episodes. Site size was not associated with CPG-inconsistent care delivery. No statistically significant association between CPG-inconsistent care and fever recurrence was observed., Conclusions: In this cohort of pediatric patients at high risk of poor FN outcomes, CPG-inconsistent care was common. Opportunities to optimize resource stewardship by boosting supportive care CPG implementation are highlighted., (© 2024 The Authors. Pediatric Blood & Cancer published by Wiley Periodicals LLC.)

- Abstract
Background: Rhinovirus (RV) positive bronchiolitis episodes in infancy confer a higher risk to develop asthma in later childhood with associated lung function impairments. We aimed to investigate the association between the type of virus causing a bronchiolitis hospitalization episode and lung ventilation inhomogeneities at preschool age., Methods: Infants hospitalized with a clinical diagnosis of moderate (ward admission) or severe (pediatric intensive care ward admission) bronchiolitis were prospectively followed-up at preschool age to assess nitrogen (N
2 ) multiple breath washout (MBW). Lung clearance index (LCI), functional residual capacity (FRC), and concentration normalized phase III slope analysis (SnIII ) indices were reported from ≥2 technically acceptable trials. Differences between groups were calculated using logistic and linear regression and adjusted for confounders (sex, age at bronchiolitis admission, height at visit, maternal asthma, and doctor-diagnosed asthma, including interaction terms between the latter three). An interaction term was included in a regression model to test for an interaction between RV bronchiolitis severity and MBW parameters at preschool age., Results: One hundred and thirty-nine subjects attended preschool follow-up, of which 84 out of 103 (82%) performing MBW had technically acceptable data. Children with a history of RV positive bronchiolitis (n = 39) had increased LCI (adjusted β-coefficient [aβ] = 0.33, 95% confidence interval [CI] 0.02-0.65, p = 0.040) and conductive airways ventilation inhomogeneity [Scond ] (aβ = 0.016, CI 0.004-0.028, p = 0.011) when compared with those with a RV negative bronchiolitis history (n = 45). In addition, we found a statistical interaction between RV bronchiolitis and bronchiolitis severity strengthening the association with LCI (aβ = 0.93, CI 0.20-1.58, p = 0.006)., Conclusion: Children with a history of hospital admission for RV positive bronchiolitis in infancy might be at a higher risk of lung ventilation inhomogeneities at preschool age, arising from the peripheral conducting airways., (© 2023 The Authors.

- Abstract
Landscape fires are increasing in frequency and severity globally. In Australia, extreme bushfires cause a large and increasing health and socioeconomic burden for communities and governments. People with asthma are particularly vulnerable to the effects of landscape fire smoke (LFS) exposure. Here, we present a position statement from the Thoracic Society of Australia and New Zealand. Within this statement we provide a review of the impact of LFS on adults and children with asthma, highlighting the greater impact of LFS on vulnerable groups, particularly older people, pregnant women and Aboriginal and Torres Strait Islander peoples. We also highlight the development of asthma on the background of risk factors (smoking, occupation and atopy). Within this document we present advice for asthma management, smoke mitigation strategies and access to air quality information, that should be implemented during periods of LFS. We promote clinician awareness, and the implementation of public health messaging and preparation, especially for people with asthma., (© 2023 The Authors.

- Abstract
Background: Cystic fibrosis (CF) lung disease starts in infancy and can be assessed for structural lung abnormalities using computed tomography or magnetic resonance scans, or for lung function impairment using multiple breath washout (MBW). However, in infancy these two methods are not well correlated. Trajectories of CF lung disease assessed by MBW in infants and toddlers remain poorly described, which is why we aimed to 1) describe the trajectory of lung function, 2) explore risk factors for progression and 3) explore the real-life effect of lumacaftor/ivacaftor., Methods: This was a nationwide observational cohort study (2018-2021) using data collected as part of the routine clinical surveillance programme (including MBW and monthly endo-laryngeal suction sampling for bacterial pathogens) in children born after implementation of newborn screening for CF (May 2016). Lumacaftor/ivacaftor commenced from age 2 years in children homozygous for F508del. Ventilation distribution efficiency (VDE), recently described to have advantages over lung clearance index (LCI), was reported as the primary MBW outcome after z-score calculations based on published reference data. Mixed effect linear regression models were the main statistical analyses performed in this study., Results: 59 children, aged 2-45 months, contributed with 211 MBW occasions (median (interquartile range (IQR)) 3 (2-5) MBW occasions per child) with a median (IQR) follow-up time of 10.8 (5.2-22.3) months. An overall mean annual deterioration rate of -0.50 (95% CI -0.78- -0.22) z-VDE was observed, starting from an estimated mean z-VDE of -1.68 (95% CI -2.15- -1.22) at age 0.0 years (intercept). Pseudomonas aeruginosa "ever" (n=14, MBWs 50) had a significantly worse z-VDE trajectory versus P. aeruginosa "never" (mean difference 0.53 (95% CI 0.16-0.89) per year; p=0.0047) and lumacaftor/ivacaftor treatment (n=22, MBWs 46) significantly improved the trajectory of z-VDE (mean difference 1.72 (95% CI 0.79-2.66) per year; p=0.0004), leading to a stable mean z-VDE trajectory after start of treatment., Conclusions: Infants and toddlers with CF demonstrated progressive deterioration in z-VDE over the first years of life. P. aeruginosa isolation "ever" was associated with an accelerated deterioration in lung function, while lumacaftor/ivacaftor therapy significantly improved and stabilised the trajectory., Competing Interests: Conflict of interest: None of the authors have personal financial relationships with any organisations that might have an interest in the submitted work., (Copyright ©The authors 2023.)

- Abstract
Following discovery of the cystic fibrosis transmembrane conductance regulator (CFTR) gene in 1989 and subsequent elucidation of the varied CFTR protein abnormalities that result, a new era of cystic fibrosis management has emerged-one in which scientific principles translated from the bench to the bedside have enabled us to potentially treat the basic defect in the majority of children and adults with cystic fibrosis, with a resultant burgeoning adult cystic fibrosis population. However, the long-term effects of these therapies on the multiple manifestations of cystic fibrosis are still under investigation. Understanding the effects of modulators in populations excluded from clinical trials is also crucial. Furthermore, establishing appropriate disease measures to assess efficacy in the youngest potential trial participants and in those whose post-modulator lung function is in the typical range for people without chronic lung disease is essential for continued drug development. Finally, recognising that a health outcome gap has been created for some people and widened for others who are not eligible for, cannot tolerate, or do not have access to modulators is important., Competing Interests: Declaration of interests In the last 36 months, unrelated to this work, JLT-C has received grants to her institution from the Cystic Fibrosis Foundation (CFF), the National Institutes of Health, Vertex Pharmaceuticals, Eloxx, and 4DMT; she has received fees from Vertex Pharmaceuticals related to consultation on clinical research design, participation on advisory boards, and speaking engagements; and has served on advisory boards or provided clinical trial design consultation for Insmed, 4DMT, and AbbVie.

- Abstract
Objective was to update a clinical practice guideline (CPG) for the management of fatigue in children and adolescents with cancer or pediatric hematopoietic cell transplant recipients. We reconvened a multi-disciplinary and multi-national panel. While the previous 2018 CPG evaluated adult and pediatric randomized controlled trials (RCTs) to manage fatigue, this 2023 update revised previous recommendations based only on pediatric RCTs. Twenty RCTs were included in the updated systematic review. Physical activity significantly reduced fatigue (standardized mean difference -0.44, 95% confidence interval -0.64 to -0.24; n = 8 RCTs). Using the 2018 recommendations as a basis, the panel continued to make strong recommendations to use physical activity, and to offer relaxation, mindfulness or both, to manage fatigue in pediatric patients. Cognitive or cognitive behavioral therapies may be offered. Pharmacological approaches should not be routinely used. The panel made a new good practice statement to routinely assess for fatigue, ideally using a validated scale., Competing Interests: PSH received grants or research support from NIH; royalties or licenses from Lippincott; consulting fees from MSKCC and participated on the REACH Board at Nemours, Delaware.

- Abstract
Mycobacterium abscessus is a nontuberculous mycobacterium (NTM) of particular concern in individuals with obstructive lung diseases such as cystic fibrosis (CF). Treatment requires multiple drugs and is characterised by high rates of relapse; thus, new strategies to limit infection are urgently required. This study sought to determine how Bacille Calmette-Guérin (BCG) vaccination may impact NTM infection, using a murine model of Mycobacterium abscessus infection and observational data from a non-BCG vaccinated CF cohort in Sydney, Australia and a BCG-vaccinated CF cohort in Cape Town, South Africa. In mice, BCG vaccination induced multifunctional antigen-specific CD4
+ T cells circulating in the blood and was protective against dissemination of bacteria to the spleen. Prior infection with M. abscessus afforded the highest level of protection against M. abscessus challenge in the lung, and immunity was characterised by a greater frequency of pulmonary cytokine-secreting CD4+ T cells compared to BCG vaccination. In the clinical CF cohorts, the overall rates of NTM sampling during a three-year period were equivalent; however, rates of NTM colonisation were significantly lower in the BCG-vaccinated (Cape Town) cohort, which was most apparent for M. abscessus . This study provides evidence that routine BCG vaccination may reduce M. abscessus colonisation in individuals with CF, which correlates with the ability of BCG to induce multifunctional CD4+ T cells recognising M. abscessus in a murine model. Further research is needed to determine the optimal strategies for limiting NTM infections in individuals with CF.- Published

- Abstract
This clinical practice guideline update provides recommendations for treating breakthrough chemotherapy-induced nausea and vomiting (CINV) and preventing refractory CINV in pediatric patients. Two systematic reviews of randomized controlled trials in adult and pediatric patients informed the recommendations. In patients with breakthrough CINV, escalation of antiemetic agents to those recommended for chemotherapy of the next higher level of emetogenic risk is strongly recommended. A similar recommendation to escalate therapy is made to prevent refractory CINV in patients who did not experience complete breakthrough CINV control and are receiving minimally or low emetogenic chemotherapy. A strong recommendation to use antiemetic agents that controlled breakthrough CINV for the prevention of refractory CINV is also made., (© 2023 The Authors.

- Abstract
Pulmonary chronic graft- versus -host disease (cGVHD) is a substantial cause of pulmonary morbidity and mortality post-haematopoietic stem cell transplantation (HSCT). Current spirometry-based monitoring strategies have significant limitations. Understanding the utility of novel peripheral airway function tests - multiple breath washout (MBW) and oscillometry - is critical in efforts to improve detection, facilitate earlier intervention and improve outcomes. In this scoping review, we identified 17 studies investigating MBW or oscillometry, or both, after allogenic HSCT. Despite small study numbers limiting the ability to draw firm conclusions, several themes were evident. Detectable peripheral airway abnormality in MBW occurred in a substantial proportion prior to HSCT. MBW indices post-HSCT were more frequently abnormal than spirometry when reporting group data and among those with extrapulmonary cGVHD and pulmonary cGVHD. Changes in MBW indices over time may be more indicative of pulmonary complications than absolute values at any given time point. Oscillometry indices were often normal at baseline, but more frequently abnormal in those who developed pulmonary cGVHD. Pooling currently available individual participant data across these studies may improve our ability to formally compare their respective sensitivity and specificity at specific time points and assess the trajectory of MBW and oscillometry indices over time., Competing Interests: Conflict of interest: N.

- Abstract
Haemoptysis occurs in up to 25 % of young people with Cystic fibrosis (CF) [1]. We undertook a literature review and described the management approach to haemoptysis in CF between 2010 and 2020 at an Australian tertiary paediatric centre, The Children's Hospital Westmead, Sydney, New South Wales, using a retrospective review of the medical records which identified 67 episodes. Sixty episodes met inclusion criteria, including 31 patients. Using the US CF Foundation guidelines, episodes were classified as scant (53.3 %), moderate (38.3 %) or massive (8.3 %). Fifty-two percent of patients were female, mean age at presentation was 15.4 years (SD+/- 2.4) and 58 % were homozygous for the Fdel508 genotype. Twelve episodes (9 patients) required bronchial artery embolization (BAE). BAE was used in all cases of massive haemoptysis 5/5 (100 %), 6/23 (22 %) episodes of moderate and 1/32 (3 %) episode of scant haemoptysis as an elective procedure for recurrent haemoptysis. Our literature review and institutional experience highlights the need for up-to-date management guidelines in the management of haemoptysis in Cystic Fibrosis. Based on our experience, we provide a proposed algorithm to help guide the management of haemoptysis in CF., Competing Interests: Conflict of Interest The authors have no conflict of interest to disclose., (Copyright © 2022.

- Abstract
Sensor errors resulting in elevated values of N
2 concentration [N2 ] in commercial multiple-breath washout (MBW) devices have been shown to prolong the washout and result in erroneously high functional residual capacity (FRC) and lung clearance index (LCI) values. The errors also affect the indices of conductive and acinar ventilatory heterogeneity ( Scond and Sacin ) although the mechanism by which this change in values occurs remains unclear. Exploring these effects also provides a timely opportunity to examine the appropriateness of the algorithm used to calculate these indices. Using a two-compartment model with differing specific ventilation (SV) such that the lower SV unit empties late, noise-free MBW were simulated both corrected and uncorrected for the recent sensor error. Scond was calculated using regression of normalized phase III slope (SnIII ) against lung turnover (TO) from a TO range starting at 1.5 and ending at an upper turnover (TOupper ) between 4 and 8 (default 6) over a range of simulated values. The principal effect of the sensor error was that as the MBW proceeded the phase III slope of successive breaths was normalized by an increasingly overestimated [N2 ], resulting in SnIII values that fell precipitously at high TO, greatly reducing Scond . Reanalysis of previously published data and of simulated data showed a large proportional bias in Scond , whereas Sacin was only minimally affected. In adult subject data, reducing TOupper below 5.5 was associated with a large drop of up to ∼60% in Scond calculated from data corrected for sensor error. Raising the upper TO limit elevated Scond by ∼20% but with a large concomitant increase in variability. In contrast to Scond , Sacin was relatively unaffected by changes in TOupper with changes of <3%. This work serves to emphasize that the upper limit of TO of 6 represents an appropriate upper limit for the calculation of Scond . NEW & NOTEWORTHY Sensor errors that elevated values of N2 concentration in commercial multiple-breath washout (MBW) devices resulted in errors in calculated parameters including Scond and Sacin . We examined the mechanism of the change in values produced by these errors and explored the appropriateness of the calculation of Scond and Sacin . This work serves to emphasize that the current algorithm in use is appropriate for the calculation of Scond and Sacin .- Published

- Abstract
We recently developed a model-based method for analyzing multiple breath nitrogen washout data that does not require identification of Phase-III. In the present study, we assessed the effect of irregular breathing patterns on the intra-subject variabilities of the model parameters. Nitrogen fraction at the mouth was measured in 18 healthy and 20 asthmatic subjects during triplicate performances of multiple breath nitrogen washout, during controlled (target tidal volume 1 L at 8-12 breaths per minute) and free (unrestricted) breathing. The parameters S
cond , Sacin and functional residual capacity (FRC) were obtained by conventional analysis of the slope of Phase-III. Fitting the model to the washout data provided functional residual capacity (FRCM ), dead space volume (VD ), the coefficient of variation of regional specific ventilation ([Formula: see text]), and the model equivalent of Sacin (Sacin-M ). Intra-participant coefficients of variation for the model parameters for both health and asthma were FRCM < 5.2%, VD < 5.4%, [Formula: see text] < 9.0%, and Sacin-M < 45.6% for controlled breathing, and FRCM < 4.6%, VD < 5.3%, [Formula: see text] < 13.2%, and Sacin-M < 103.2% for free breathing. The coefficients of variation limits for conventional parameters were FRC < 6.1%, with Scond < 73.6% and Sacin < 49.2% for controlled breathing and Scond < 35.0% and Sacin < 74.4% for free breathing. The model-fitting approach to multiple breath nitrogen washout analysis provides a measure of regional ventilation heterogeneity in [Formula: see text] that is less affected by irregularities in the breathing pattern than its corresponding Phase-III slope analysis parameter Scond ., (© 2022.
