Evaluation of treatment and long-term management of anaphylaxis in pediatric departments of Greece: a 2-year nationwide survey.

BACKGROUND: Anaphylaxis proportions of incidence are increasing globally. However, limited data are available regarding anaphylaxis in the pediatric population of Greece. PURPOSE: The aim of the study was to evaluate management of anaphylaxis in Greek pediatric departments. METHODS: We performed a questionnaire-based study of children aged less than 16 years presenting with anaphylaxis in 10 national pediatric hospitals over a period of 2 years. Management of anaphylaxis was assessed prior to and after an informative intervention. RESULTS: In all, 127 cases of anaphylaxis were identified. Epinephrine was administered in almost half of all cases (51.2%), predominantly through intramuscular route (88.5%), while the majority of anaphylaxis patients were treated with antihistamines (92.9%) and corticosteroids (70.1%). Epinephrine was more likely administered by physicians if the elicitor was a drug (P < 0.003). Regarding long-term management, an epinephrine auto-injector was prescribed in 66.9% of patients. Follow-up information was available for most of the patients (92.9%), the majority of whom (76.3%) were referred to an allergist. More than half of these patients (63.6%) had a documented allergy follow-up, which identified a causative allergen in 53.3% of cases. No statistically significant differences were recorded prior to and after the intervention regarding management of anaphylaxis. CONCLUSIONS: This nationwide study highlighted the necessity of further improvement in terms of anaphylaxis treatment and secondary prevention measures. This presupposes appropriate education and training of healthcare professionals, thus contributing to proper and comprehensive care of the pediatric population.

The Presence of Smoking and Alcohol Imaginary in Popular Movies Available in Netflix Online Streaming Platform.

Exposure of tobacco and alcohol consumption in media and filmmaking has been related to promotion of smoking and drinking in adults. Current regulation aims to restrict tobacco and alcohol advertising in order to avoid alcohol consumption and smoking habits. We aimed to assess the impact of smoking and drinking habits in video-on-demand services. Three independent investigators watched the 50 most popular movies available in Netflix streaming platform, according to York Times and recorded incidence of smoking and drinking scenes for both primary and secondary actors. 45 movies were included in our analysis. Main characters appeared to smoke in 19 movies and to consume alcohol in 33 movies, while secondary characters in 32 movies with 121 scenes and consumed alcohol in 38 movies, respectively. First actors were males in 22 movies, females in 7 movies and both males and females in 6 movies. Movies' directors were males in 29 movies and females in 6 movies. Our analysis found increased content of smoking and drinking scenes in online movies and showed that recently released movies presented with increased incidence of drinking and smoking scenes, while era depicted in movies also affects smoking and drinking content.

Factors Affecting CPAP Adherence in an OSA Population during the First Two Years of the COVID-19 Pandemic.

Background: Obstructive sleep apnea (OSA) is a common disorder associated with major cardiovascular and neurocognitive sequelae. Continuous positive airway pressure (CPAP) is the standard treatment for OSA. The aim of this study was to investigate the prevalence and associations of long-term CPAP adherence in newly diagnosed OSA patients. Methods: We enrolled patients who were diagnosed with OSA during the COVID-19 pandemic. Adherence was defined as CPAP use ≥4 h per night on ≥70% of nights over 30 consecutive days. Patient demographics were retrieved from medical records, and CPAP adherence at 6 months and 1 year after initiation was monitored. Results: Overall, 107 patients were included in the analysis. A number of 73 (68%) and 63 (59%) patients were adherent to CPAP treatment at 6 months and 12 months accordingly. Among the factors examined and analyzed (age, gender, BMI, Apnea-Hypopnea Index (AHI)), no significant correlation was found. Further analysis revealed the potential role of comorbidities. CPAP compliance at 6 months was shown to be associated with better CPAP adherence at 12 months. Conclusions: CPAP adherence at 6 months is correlated to long-term adherence to treatment. Therefore, early close follow-up is important. Further prospective studies are needed to identify other potential predictors.

"The Saint" gone good. Smoking and drinking over time in the popular series.

BACKGROUND: Alcohol-related health and social problems are prevalent in almost all societies that consume alcohol and the presence of alcohol use in the movies is a known issue. The same holds true for smoking prevalence in film-making. OBJECTIVES: The aim of this study is to assess tobacco-related content and alcohol consumption in "The Saint" series and movies. METHODS: Five episodes from each "The Saint" TV series, from the '60s, were randomly selected. A predefined template was used for data collection and multiple variables were recorded and then analyzed. RESULTS: The main character was reported to smoke in 81.9% of episodes and consume alcohol in 87.1% episodes and similar were the results for supporting actors. Mean time to first cigarette and first drink ranged from 0.5 to 40 minutes and from 0.5 to 40.5 minutes, respectively. CONCLUSION: The prevalence of smoking and drinking in "The Saint" movies is high on average; however, the main character has ceased smoking and reduced alcohol consumption in the two contemporary movies, probably following the changes in the era and respecting the law.

Cardiopulmonary exercise testing in people with minimally impaired multiple sclerosis.

BACKGROUND: Multiple sclerosis (MS) is a chronic demyelinating inflammatory disorder of the central nervous system that may affect respiratory system at the later stages of the disease. The aim of our study was to evaluate respiratory function and cardiopulmonary exercise testing in ambulatory without aid people with MS (pwMS), and to investigate quality of life parameters and fatigue in this population. METHODS: 25 pwMS and 16 healthy controls were included in this study. Pulmonary function tests were performed and were followed by proper cardiopulmonary exercise testing with the use of treadmill. Quality of life assessment was done with SF-36 questionnaire. RESULTS: The mean age of the patient group was 38.4 ± 8.2 years. Spirometric values were within normal limits, and so did lung diffusion capacity, while maximal voluntary ventilation was reduced. In cardiopulmonary exercise testing the patient group showed impairment compared to control group. The statistically significant lower parameters were V'O2 peak, V'CO2 peak, RER, V'O2/kg peak, V'CO2/kg peak, oxygen pulse peak and V'E/V'CO2 slope. Moreover, there was a negative and statistically significant correlation between CPET values and BMI and MFIS, while there was a positive and statistically significant correlation with quality of life, evaluated by SF-36. CONCLUSION: Our study showed that the main cardiopulmonary exercise testing parameters were affected in ambulatory pwMS, even without evidence of respiratory symptoms. Therefore, these people should be evaluated for pulmonary function compromise.

Novel volumetric capnography indices measure ventilation inhomogeneity in cystic fibrosis.

Background: Volumetric capnography (VCap) is a simpler alternative to multiple-breath washout (MBW) to detect ventilation inhomogeneity in patients with cystic fibrosis (CF). However, its diagnostic performance is influenced by breathing dynamics. We introduce two novel VCap indices, the capnographic inhomogeneity indices (CIIs), that may overcome this limitation and explore their diagnostic characteristics in a cohort of CF patients. Methods: We analysed 320 N2-MBW trials from 50 CF patients and 65 controls (age 4-18 years) and calculated classical VCap indices, such as slope III (SIII) and the capnographic index (KPIv). We introduced novel CIIs based on a theoretical lung model and assessed their diagnostic performance compared to classical VCap indices and the lung clearance index (LCI). Results: Both CIIs were significantly higher in CF patients compared with controls (mean±sd CII1 5.9±1.4% versus 5.1±1.0%, p=0.002; CII2 7.7±1.8% versus 6.8±1.4%, p=0.002) and presented strong correlation with LCI (CII1 r2=0.47 and CII2 r2=0.44 in CF patients). Classical VCap indices showed inferior discriminative ability (SIII 2.3±1.0%/L versus 1.9±0.7%/L, p=0.013; KPIv 3.9±1.3% versus 3.5±1.2%, p=0.071), while the correlation with LCI was weak (SIII r2=0.03; KPIv r2=0.08 in CF patients). CIIs showed lower intra-subject inter-trial variability, calculated as coefficient of variation for three and relative difference for two trials, than classical VCap indices, but higher than LCI (CII1 11.1±8.2% and CII2 11.0±8.0% versus SIII 16.3±13.5%; KPIv 15.9±12.8%; LCI 5.9%±4.2%). Conclusion: CIIs detect ventilation inhomogeneity better than classical VCap indices and correlate well with LCI. However, further studies on their diagnostic performance and clinical utility are required.

Exercise Limitation in Children and Adolescents with Mild-to-Moderate Asthma.

BACKGROUND: Children with uncontrolled asthma are less tolerant to exercise due to ventilatory limitation, exercise-induced bronchoconstriction (EIB), or physical deconditioning. The contribution of these factors in children with controlled mild-to-moderate asthma is unknown. OBJECTIVE: To explore the underlying mechanisms of reduced exercise capacity in children with controlled mild-to-moderate asthma. METHODS: This was a cross-sectional study of 45 children and adolescents (age 8-18 years) with controlled mild-to-moderate asthma (asthma control test score 21-25) and 61 age-matched healthy controls. All participants completed a physical activity questionnaire and performed spirometry and cardiopulmonary exercise testing (CPET; maximal incremental protocol). Spirometric indices and CPET parameters were compared between the two groups. The effect of EIB (FEV1 decrease >10% post CPET), ventilatory limitation and physical deconditioning on maximum oxygen uptake (O2peak), was assessed by multivariable linear regression. RESULTS: 62.2% of children with asthma and 29.5% of controls (P = 0.002) were categorized as inactive. Reduced exercise capacity (O2peak <80%) was noted in 53.3% of asthmatics and 16.4% of controls (P < 0.001). EIB was documented in 11.1% of participants with asthma. Physical deconditioning was noted in 37.8% of children with asthma and in 14.8% of controls (P = 0.013). Physical deconditioning emerged as the only significant determinant of O2peak, irrespective of asthma diagnosis, body mass index, ventilatory limitation and EIB. CONCLUSION: Children with controlled mild-to-moderate asthma are less tolerant to strenuous exercise than their healthy peers. The decreased exercise capacity in this population should mainly be attributed to physical deconditioning, while the contribution of ventilatory limitation and EIB is rather small.
