Adherence to dietary recommendations, nutrient intake adequacy and diet quality among pediatric cystic fibrosis patients: results from the greecf study
Nutrition is an important component of cystic fibrosis (CF) therapy, with a high-fat diet being the cornerstone of treatment. However, adherence to the dietary recommendations for CF appears suboptimal and burdensome for most children and adolescents with CF, leading to malnutrition, inadequate growth, compromised lung function and increased risk for respiratory infections. A cross-sectional approach was deployed to examine the degree of adherence to the nutrition recommendations and diet quality among children with CF. A total of 76 children were recruited from Aghia Sophia’s Children Hospital, in Athens, Greece. In their majority, participants attained their ideal body weight, met the recommendations for energy and fat intake, exceeding the goal for saturated fatty acids consumption. Carbohydrate and fiber intake were suboptimal and most participants exhibited low or mediocre adherence to the Mediterranean diet prototype. It appears that despite the optimal adherence to the energy and fat recommendations, there is still room for improvement concerning diet quality and fiber intake.info:eu-repo/semantics/publishedVersio
Nocturnal Oximetry-based Evaluation of Habitually Snoring Children
Rationale: The vast majority of children around the world
undergoing adenotonsillectomy for obstructive sleep
apnea–hypopnea syndrome (OSA) are not objectively diagnosed by
nocturnal polysomnography because of access availability and cost
issues. Automated analysis of nocturnal oximetry (nSpO2), which is
readily and globally available, could potentially provide a reliable and
convenient diagnostic approach for pediatric OSA.
Methods: DeidentifiednSpO2 recordings froma total of 4,191 children
originating from13 pediatric sleep laboratories around the worldwere
prospectively evaluated after developing and validating an automated
neural network algorithm using an initial set of single-channel nSpO2
recordings from 589 patients referred for suspected OSA.
Measurements and Main Results: The automatically
estimated apnea–hypopnea index (AHI) showed high
agreement with AHI from conventional polysomnography
(intraclass correlation coefficient, 0.785) when tested in 3,602
additional subjects. Further assessment on the widely used AHI
cutoff points of 1, 5, and 10 events/h revealed an incremental
diagnostic ability (75.2, 81.7, and 90.2% accuracy; 0.788, 0.854, and
0.913 area under the receiver operating characteristic curve,
respectively).
Conclusions: Neural network–based automated analyses of
nSpO2 recordings provide accurate identification of OSA
severity among habitually snoring children with a high pretest
probability of OSA. Thus, nocturnal oximetry may enable a
simple and effective diagnostic alternative to nocturnal
polysomnography, leading to more timely interventions and
potentially improved outcomes.Supported in part by project VA037 U16 from the Consejer´ıa de Educacio´ n de la Junta de Castilla y Leo´ n and the European Regional Development Fund (FEDER), project RTC-2015-3446-1 from the Ministerio de Econom´ıa y Competitividad and FEDER, and project 153/2015 of the Sociedad Espan˜ ola de Neumolog´ıa y Cirug´ıa Tora´ cica (SEPAR).

Inflammation and Infection in Cystic Fibrosis: Update for the Clinician
Inflammation and infection play an important role in the pathophysiology of cystic fibrosis, and they are significant causes of morbidity and mortality in CF. The presence of thick mucus in the CF airways predisposes to local hypoxia and promotes infection and inflammation. A vicious cycle of airway obstruction, inflammation, and infection is of critical importance for the progression of the disease, and new data elucidate the different factors that influence it. Recent research has been focused on improving infection and inflammation in addition to correcting the basic gene defect. This review aims to summarize important advances in infection and inflammation as well as the effect of new treatments modulating the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein. New approaches to target infection and inflammation are being studied, including gallium, nitric oxide, and phage therapy for infection, along with retinoids and neutrophil elastase inhibitors for inflammation
Omalizumab Therapy for Allergic Bronchopulmonary Aspergillosis in Children with Cystic Fibrosis: A Synthesis of Published Evidence
Allergic bronchopulmonary aspergillosis (ABPA) complicating cystic
fibrosis (CF) is treated with corticosteroids. Since elevated IgE is a
cardinal abnormality, anti-IgE has been used sporadically as adjuvant
treatment. In eight case reports, 13 children with CF and ABPA received
anti-IgE resulting in improved FEV1, fewer respiratory symptoms and
decreased corticosteroid use. Pediatr Pulmonol. 2014; 49:503-507. (c)

Efficacy of Pulse Methylprednisolone in a Pediatric Case of Postinfectious Bronchiolitis Obliterans
Postinfectious bronchiolitis obliterans is a chronic incapacitating
disease with persistent airway inflammation. However, the efficacy of
systemic corticosteroids has never been studied systematically. In the
presented case, serial spirometry, plethysmography measurements, and
nocturnal oximetry demonstrated progressive decline in lung
hyperinflation and air-trapping and improvement in expiratory function
and nocturnal oxygenation during and after six three-day courses of
high-dose methylprednisolone (30mg/kg/day). At four months post
treatment, most gain in lung function was lost suggesting the need for
sustained immunosuppression. Randomized, controlled trials using serial
plethysmography measurements, spirometry, and nocturnal oximetry could
provide evidence for the management of postinfectious bronchiolitis
obliterans. Pediatr Pulmonol. 2015; 50:E13-E16. (c) 2015 Wiley

Home sleep testing for the diagnosis of pediatric obstructive sleep apnea: the times they are a changing ... !
Purpose of review
The current paradigm shift in the diagnosis of sleep apnea in adults has
further emphasized the urgent need for the development and validation of
less inconvenient and laborious approaches than the in-laboratory
nocturnal polysomnography for evaluation of children.
Recent findings
These efforts have been primarily centered around the following: first,
refinements and validation of questionnaires; second, single-channel
recordings such as oximetry, airflow, or ECG; third, home-based
polysomnography and polygraphy; and fourth, biomarkers. The major
overall findings emanating from such studies indicate that none of the
approaches provides an ideal substitute to in-laboratory nocturnal
polysomnography. Conversely, many of the proposed approaches enable
effective screening in a cost-effective manner, and may be particularly
suitable when access to pediatric sleep medicine facilities is limited
or unavailable.
Summary
The overall improvements in technologies and in our understanding of
pediatric sleep-disordered breathing should enable population-tailored
effective home-based diagnostic approaches that reduce the overall
burden to the family, while achieving high levels of diagnostic
accuracy. Newer algorithms will have to be developed and validated to
allow for effective implementation of such approaches
Nebulizer Care and Inhalation Technique in Children with Cystic Fibrosis
Nebulizers are used by the great majority of cystic fibrosis patients for delivery of cornerstone treatments. Inhalation technique and adequate disinfection and maintenance are important for optimizing medication delivery. In this study, inhalation technique and nebulizer disinfection/maintenance were assessed in cystic fibrosis patients by direct observation in clinic and completion of a scoring sheet. A total of 108 patients were recruited. The maximum inhalation technique score was attained by 30.5% and adequate inhalation technique score by 74.08% of patients. The inhalation technique score was best with the vibrating mesh nebulizer (p = 0.038), while patient age and number of nebulized medications did not affect ITS significantly (p > 0.05). Nebulizer disinfection/maintenance score was excellent in only 31.48%. Most families kept the nebulizer clean and used appropriate disinfection method, but only half of them replaced the nebulizer and nebulizer cup at the recommended time intervals. Nebulizer disinfection/maintenance score was positively affected by a number of nebulized medications and negatively by years of equipment use (p = 0.009 and p = 0.001, respectively). Even though inhalation technique and disinfection/maintenance practices were found to be adequate in a large proportion of cases, there is still a need for regular review and education. The type of nebulizer was associated with improved inhalation technique, but more data are required before making specific recommendations
