Parenting and Gender as Impact Factors for Social Participation, Quality of Life, and Mental Health in Long COVID.

OBJECTIVES: This study aims to investigate the impact of gender and parental tasks on social participation, health-related quality of life (hrQoL), and mental health in persons with long COVID. METHODS: A mixed-methods approach was followed including a cross-sectional web-based survey and semi-structured interviews. Multivariable linear regressions were used to quantify the effect of gender and parenting tasks on social participation, hrQoL, and mental health. Qualitative data from interviews with participants experiencing long COVID symptoms was analyzed using content analysis. RESULTS: Data from 920 participants in the quantitative study and 25 participants in the qualitative study was analyzed. Parenting tasks were associated with increased impairments in family and domestic responsibilities in persons with long COVID compared to lower impairments in persons without long COVID (P = .02). The qualitative data indicate that coping with long COVID and pursuing parenting tasks limit participants' ability to perform leisure activities and attend social gatherings. In long COVID, men had higher anxiety symptoms than women, and in those without long COVID, the opposite was observed (P < .001). In the qualitative study, participants expressed feelings of dejection and pessimism about their future private, occupational, and health situations. No differences between the genders could be observed. CONCLUSIONS: Long COVID is associated with impairments in family and domestic responsibilities in individuals who have parenting tasks. Among participants with long COVID, anxiety symptoms are higher in men than women.

Spirometric and anthropometric improvements in response to elexacaftor/tezacaftor/ivacaftor depending on age and lung disease severity.

Introduction: Triple-combination cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapy with elexacaftor/tezacaftor/ivacaftor (ETI) was introduced in August 2020 in Germany for people with CF (pwCF) ≥12 years (yrs.) of age and in June 2021 for pwCF ≥6 yrs of age. In this single-center study, we analyzed longitudinal data on the percent-predicted forced expiratory volume (ppFEV1) and body-mass-index (BMI) for 12 months (mo.) after initiation of ETI by linear mixed models and regression analyses to identify age- and severity-dependent determinants of response to ETI. Methods: We obtained data on 42 children ≥6-11 yrs, 41 adolescents ≥12-17 yrs, and 143 adults by spirometry and anthropometry prior to ETI, and 3 and 12 mo. after ETI initiation. Data were stratified by the age group and further sub-divided into age-specific ppFEV1 impairment. To achieve this, the age strata were divided into three groups, each according to their baseline ppFEV1: lowest 25%, middle 50%, and top 25% of ppFEV1. Results: Adolescents and children with more severe lung disease prior to ETI (within the lowest 25% of age-specific ppFEV1) showed higher improvements in lung function than adults in this severity group (+18.5 vs. +7.5; p = 0.002 after 3 mo. and +13.8 vs. +7.2; p = 0.012 after 12 mo. of ETI therapy for ≥12-17 years and +19.8 vs. +7.5; p = 0.007 after 3 mo. for children ≥6-11 yrs). In all age groups, participants with more severe lung disease showed higher BMI gains than those with medium or good lung function (within the middle 50% or top 25% of age-specific ppFEV1). Regression analyses identified age as a predictive factor for FEV1 increase at 3 mo. after ETI initiation, and age and ppFEV1 at ETI initiation as predictive factors for FEV1 increase 12 mo. after ETI initiation. Discussion: We report initial data, which suggest that clinical response toward ETI depends on age and lung disease severity prior to ETI initiation, which argue for early initiation of ETI.

Differential effects of ELX/TEZ/IVA on organ-specific CFTR function in two patients with the rare CFTR splice mutations c.273+1G>A and c.165-2A>G.

Introduction: Evidence for the efficiency of highly-effective triple-CFTR-modulatory therapy with elexacaftor/tezacaftor/ivacaftor (ETI), either demonstrated in clinical trials or by in vitro testing, is lacking for about 10% of people with cystic fibrosis (pwCF) with rare mutations. Comprehensive assessment of CFTR function can provide critical information on the impact of ETI on CFTR function gains for such rare mutations, lending argument of the prescription of ETI. The mutation c.165-2A>G is a rare acceptor splice mutation that has not yet been functionally characterized. We here describe the functional changes induced by ETI in two brothers who are compound heterozygous for the splice mutations c.273+1G>C and c.165-2A>G. Methods: We assessed the effects of ETI on CFTR function by quantitative pilocarpine iontophoresis (QPIT), nasal potential difference measurements (nPD), intestinal current measurements (ICM), ß-adrenergic sweat secretion tests (SST) and multiple breath washout (MBW) prior to and 4 months after the initiation of ETI. Results: Functional CFTR analysis prior to ETI showed no CFTR function in the respiratory and intestinal epithelia and in the sweat gland reabsorptive duct in either brother. In contrast, ß-adrenergic stimulated, CFTR-mediated sweat secretion was detectable in the CF range. Under ETI, both brothers continued to exhibit high sweat chloride concentration in QPIT, evidence of low residual CFTR function in the respiratory epithelia, but normalized ß-adrenergically stimulated production of primary sweat. Discussion: Our results are the first to demonstrate that the c.165-2A>G/c.273+1G>C mutation genotype permits mutant CFTR protein expression. We showed organ-specific differences in the expression of CFTR and consecutive responses to ETI of the c.165-2A>G/c.273+1G>C CFTR mutants that are probably accomplished by non-canonical CFTR mRNA isoforms. This showcase tells us that the individual response of rare CFTR mutations to highly-effective CFTR modulation cannot be predicted from assays in standard cell cultures, but requires the personalized multi-organ assessment by CFTR biomarkers.

Comparison of Three Eradication Treatment Protocols for Pseudomonas Aeruginosa in Children and Adolescents with Cystic Fibrosis.

BACKGROUND: Pseudomonas aeruginosa (Pa) continues to affect disease progression in cystic fibrosis (CF). However, the best eradication regimen remains unclear. This work compares three different antibiotic eradication regimens in pediatric CF: an administration according to a standard-operating procedure (SOP) order vs. administration outside of this order (ooSOP). METHODS: This observational study includes all CF patients<18 years who received one of three Pa eradication treatments in the past eight years at our center: 1) inhaled high-dose tobramycin (Hi-TOBI), 2) inhaled colistin+oral ciprofloxacin (COL/Cip), 3) inhaled low-dose tobramycin+4 intravenous 14-day Pa active antibiotic treatments (lo-Tobra/IV). We compared eradication rates of the three treatment regimens performed according to the SOP-based order vs. ooSOP. Logistic regression analysis was performed to identify risk factors for eradication failure. RESULTS: Performed according to SOP order, Hi-TOBI showed the greatest efficacy, followed by lo-Tobra/IV and finally COL/Cip, while ooSOP lo-Tobra/IV was most successful, followed by COL/Cip and Hi-TOBI. Previous Pa-infections and Pa-therapies along with age at CF diagnosis were risk factors for eradication failure. CONCLUSION: Antibiotic treatment in SOP-based pre-defined order leads to significantly better eradication rates than individual modifications of the order of administration. A short course of inhalational high-dose Tobramycin is most successful at the first attempt. Prolonged antibiotic therapy seems to improve eradication after failed initial attempts.

Pulmonary Alveolar Microlithiasis: A novel patient and brief review of the literature.

Pulmonary Alveolar Microlithiasis (PAM) is a rare hereditary lung disease caused by biallelic pathogenic variants (pV) in the solute family 34 member 2 gene (SLC34A2; Izumi et al., Am J Respir Crit Care Med 2007; 175: 263-268). pVs in this sodium phosphate co-transporter gene lead to accumulation of calcium phosphate crystals within pulmonary alveoli. More than 1000 cases of PAM were thus far reported, with high variance in disease courses (Stamatis et al., Ann Thorac Surg 1993; 56: 972-975). Frequently, asymptomatic cases are observed, and often times slow disease progression until respiratory insufficiency in middle age occurs (Kosciuk, Eur Respir Rev 2020; 29: 200024). Treatment options for PAM are scarce and largely ineffective, and lung transplantation is the only effective therapy in end-stage disease (Stamatis et al., Ann Thorac Surg 1993; 56: 972-975). Here, we report a novel PAM case in an adolescent migrant from East Africa and discuss current diagnostic and therapeutic options.

Hepatitis E, Schistosomiasis and Echinococcosis-Prevalence in a Cohort of Pregnant Migrants in Germany and Their Influence on Fetal Growth Restriction.

BACKGROUND: Infections, as well as adverse birth outcomes, may be more frequent in migrant women. Schistosomiasis, echinococcosis, and hepatitis E virus (HEV) seropositivity are associated with the adverse pregnancy outcomes of fetal growth restriction and premature delivery. METHODS: A cohort study of 82 pregnant women with a history of migration and corresponding delivery of newborns in Germany was conducted. RESULTS: Overall, 9% of sera tested positive for anti-HEV IgG. None of the patients tested positive for anti-HEV IgM, schistosomiasis, or echinococcus serology. Birth weights were below the 10th percentile for gestational age in 8.5% of the neonates. No association between HEV serology and fetal growth restriction (FGR) frequency was found. CONCLUSIONS: In comparison to German baseline data, no increased risk for HEV exposure or serological signs of exposure against schistosomiasis or echinococcosis could be observed in pregnant migrants. An influence of the anti-HEV serology status on fetal growth restriction could not be found.

The First 4 Years - Outcome of Children Identified by Newborn Screening for CF in Germany.

BACKGROUND: Newborn screening (NBS) has been shown to improve cystic fibrosis (CF) disease course and has been widely implemented worldwide. This monocentric study compared children diagnosed by NBS vs. a cohort preceding the implementation of NBS in Germany in 2016 to evaluate ascribed benefits of NBS. METHODS: We compared all children with confirmed CF diagnosis (n=19, "NBS group") out of all children presenting with positive NBS at our center after implementation of NBS (n=100) to children diagnosed with CF at our center within 4 years before NBS implementation (n=29, "pre-NBS group") for outcomes of anthropometry, gastrointestinal and pulmonary disease manifestations and respiratory microbiology. RESULTS: Children diagnosed by NBS had a lower incidence of initial difficulty to thrive (15 vs. 41%) and showed higher mean z-scores for Body-Mass-Index (BMI), weight and length at diagnosis and during study period. Children in the pre-NBS group displayed higher proportions of oxygen-dependent pulmonary exacerbations (10 vs. 0%). They show a significantly lower amount of normal bacterial flora (p=0.005) along with a significantly higher number of throat swab cultures positive for Pseudomonas aeruginosa (p=0.0154) in the first year of life. Yet, pulmonary imaging did not reveal less pulmonary morbidity in the NBS group. CONCLUSIONS: Our results confirm that NBS for CF leads to earlier diagnosis and improves nutritional outcomes in early childhood. Although trajectories of structural lung damage at early age were unaffected by NBS, NBS positive CF patients at preschool age displayed less pulmonary exacerbations and pathological bacteria in throat swabs.

Acute respiratory infections in an adult refugee population: an observational study.

The presence of acute infectious respiratory diseases (ARD) is one of the main reasons why recently arrived refugees seek medical help. This paper investigates the incidence rates of acute respiratory diseases in an adult refugee population as well as associated sociodemographic factors and drug treatments. We conducted a retrospective observational study of deidentified medical records. The data were collected between 2015 and 2019 in the health care centers of two large German initial reception centers for refugees. Multivariable analyses controlling for sociodemographics were carried out using generalized estimating equations. Out of 10,431 eligible residents, 6965 medical encounters of 2840 adult patients were recorded over 30 months. Of all the adult patients, 34.4% sought medical help for a respiratory symptom or diagnosis at least once. Older patients and patients from Sub-Saharan Africa sought help less often. The occurrence of ARD showed a typical distribution over the course of the year. Facility occupancy was not associated with ARD occurrence. Acute respiratory symptoms are a leading cause for adult refugee patients to seek medical care. The doctor contact rates due to ARD were consistently two to three times higher among refugees than among German residents.

Disease burden in a large cohort of asylum seekers and refugees in Germany.

BACKGROUND: Currently, health care systems worldwide are challenged with providing care to an increasing number of migrants, refugees, and displaced persons. In this article, we report on disease burden and drug prescription patterns in a large refugee cohort in Germany. METHODS: We conducted a cross-sectional study of anonymized medical records including demographic data, diagnoses, and drug prescriptions in two refugee reception centres between 2015 and 2019. Refugees and migrants received medical assistance exclusively through the on-site clinics. Thus, this study represents all medical visits of the housed residents. RESULTS: In total, n = 15531 diagnoses from n = 4858 patients in a cohort of n = 10431 accommodated refugees were recorded. N = 11898 medications were prescribed. Overall, 29.8% of all refugees sought medical attention. Half of the patients were female (49.6%), the average age was 23.8 years (SD [standard deviation] 17.0, min 0, max 81), and 41.5% were minors (<18 years). Most patients had Middle Eastern or Northern African origin (63.9%). The largest proportion of diagnoses belonged to the ICD (International Statistical Classification of Diseases and Related Health Problems) category "R" (miscellaneous, 33.5%), followed by diseases of the respiratory system (category "J", 16.5%), or the musculoskeletal system (category "M", 7.1%). Non-steroidal anti-inflammatory drugs were most frequently prescribed. CONCLUSIONS: This analysis in two large refugee centres in Germany shows that about one third of refugees seek medical attention upon initial arrival. Complaints are manifold, with a high prevalence of respiratory infections.

Fetal growth restriction in a cohort of migrants in Germany.

BACKGROUND: Migrant women may have an increased risk of adverse birth outcomes. This study analyses the occurrence of low birth weight, preterm birth and intrauterine growth restriction / fetal growth restriction (IUGR/FGR) in pregnant migrants. METHOD: Cross-sectional study of 82 mother-child pairs of pregnant migrants attending medical care in Germany. RESULTS: The Median age was 27 years, 49% of patients were of oriental-asian ethnicity and median year of migration was 2015. At least one previous pregnancy was reported in 76% of patients, in 40% the delivery mode was caesarian section. Median gestational age was 39.7 weeks. Preterm birth occurred in 6.1% of pregnancies. Median gestational age for preterm birth was 32.3 weeks. Low birth weight (< 2500 g) occurred in 6.1%. Birth weights below the 10th percentile of birth weight for gestational age were observed in 8.5% of the total cohort. CONCLUSIONS: Compared to German data no increased occurrence of low birth weight, preterm birth or IUGR/FGR was found. We note that the rate of caesarian section births was higher than in the general population for reasons yet to be identified. The authors propose stratification according to migration status for the national documentation of birth outcomes in Germany.

Intestinal current measurement and nasal potential difference to make a diagnosis of cases with inconclusive CFTR genetics and sweat test.

BACKGROUND: Nasal potential difference (NPD) and intestinal current measurements (ICM) are cystic fibrosis transmembrane conductance regulator (CFTR) biomarkers recommended to make a diagnosis in individuals with inconclusive sweat test and CFTR genetics and a clinical suspicion for cystic fibrosis (CF) or CFTR-related disorder (CFTR-RD). METHODS: NPD and ICM were measured according to standard operating procedures of the European Cystic Fibrosis Society Diagnostic Network Working Group. RESULTS: We assessed 219 individuals by NPD or ICM who had been referred to our laboratory due to clinical symptoms suggestive of CF, but inconclusive sweat test and CFTR genetics (median age: 16.3 years, range 0.4 to 76 years). CF or CFTR-related disorder was diagnosed in 22 of 29 patients (76%) with a CFTR genotype of unknown or variable clinical significance and in 51 of 190 carriers (27%) of one (35/42) or no (16/148) identified CFTR mutation. If two CFTR sequence variants had been identified, the outcome of NPD and ICM was consistent with the classification of the CFTR2 database. Moreover, a suspected false-positive diagnosis of CF was confirmed in seven and withdrawn in eight patients. Of 26 individuals assessed by both NPD and ICM, eleven individuals exhibited discordant tracings of ICM and NPD, with one measurement being in the CF range and the other in the normal range. CONCLUSION: The majority of patients whom we diagnosed with CF or CFTR-RD by extended electrophysiology are carriers of the wild-type CFTR coding sequence on at least one of their CF alleles. The disease-causing genetic lesions should reside in the non-coding region of CFTR or elsewhere in the genome, affecting the regulation of CFTR expression in a tissue-depending fashion which may explain the large within-group variability of CFTR activity in the respiratory and intestinal epithelium seen in this group.

Strategic Anti-SARS-CoV-2 Serology Testing in a Low Prevalence Setting: The COVID-19 Contact (CoCo) Study in Healthcare Professionals.

BACKGROUND: Serology testing is explored for epidemiological research and to inform individuals after suspected infection. During the coronavirus disease 2019 (COVID-19) pandemic, frontline healthcare professionals (HCP) may be at particular risk for infection. No longitudinal data on functional seroconversion in HCP in regions with low COVID-19 prevalence and low pre-test probability exist. METHODS: In a large German university hospital, we performed weekly questionnaire assessments and anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G (IgG) measurements with various commercial tests, a novel surrogate virus neutralisation test, and a neutralisation assay using live SARS-CoV-2. RESULTS: From baseline to week 6, 1080 screening measurements for anti-SARS CoV-2 (S1) IgG from 217 frontline HCP (65% female) were performed. Overall, 75.6% of HCP reported at least one symptom of respiratory infection. Self-perceived infection probability declined over time (from mean 20.1% at baseline to 12.4% in week 6, p < 0.001). In sera of convalescent patients with PCR-confirmed COVID-19, we measured high anti-SARS-CoV-2 IgG levels, obtained highly concordant results from enzyme-linked immunosorbent assays (ELISA) using e.g. the spike 1 (S1) protein domain and the nucleocapsid protein (NCP) as targets, and confirmed antiviral neutralisation. However, in HCP the cumulative incidence for anti-SARS-CoV-2 (S1) IgG was 1.86% for positive and 0.93% for equivocal positive results over the study period of 6 weeks. Except for one HCP, none of the eight initial positive results were confirmed by alternative serology tests or showed in vitro neutralisation against live SARS-CoV-2. The only true seroconversion occurred without symptoms and mounted strong functional humoral immunity. Thus, the confirmed cumulative incidence for neutralizing anti-SARS-CoV-2 IgG was 0.47%. CONCLUSION: When assessing anti-SARS-CoV-2 immune status in individuals with low pre-test probability, we suggest confirming positive results from single measurements by alternative serology tests or functional assays. Our data highlight the need for a methodical serology screening approach in regions with low SARS-CoV-2 infection rates. TRIAL REGISTRATION: The study is registered at DRKS00021152.

Factors Influencing the Frequency of Airway Infections in Underage Refugees: A Retrospective, Cross Sectional Study.

Background: Infections are a leading cause of refugee morbidity. Recent data on the rate of airway infections and factors influencing their spread in refugee reception centers is scarce. Methods: A retrospective, cross-sectional study of de-identified medical records with a focus on respiratory infections in underage refugees was conducted at two large German refugee reception centers. Results: In total, medical data from n = 10,431 refugees over an observational period of n = 819 days was analyzed. Among pediatric patients (n = 4289), 55.3% presented at least once to the on-site medical ward with an acute respiratory infection or signs thereof. In 38.4% of pediatric consultations, acute airway infections or signs thereof were present. Airway infections spiked during colder months and were significantly more prevalent amongst preschool and resettled children. Their frequency displayed a positive correlation with the number of refugees housed at the reception centers. Conclusions: We show that respiratory infections are a leading cause for morbidity in young refugees and that their rate is influenced age, season, status, and residential density. This illustrates the need to protect refugee children from contracting airway infections which may also reduce the spread of coronavirus disease 2019 (COVID-19) during the current pandemic.

COVID-19 related reduction in pediatric emergency healthcare utilization - a concerning trend.

BACKGROUND: The COVID-19 pandemic has disrupted healthcare systems worldwide. In addition to the direct impact of the virus on patient morbidity and mortality, the effect of lockdown strategies on health and healthcare utilization have become apparent. Little is known on the effect of the pandemic on pediatric and adolescent medicine. We examined the impact of the pandemic on pediatric emergency healthcare utilization. METHODS: We conducted a monocentric, retrospective analysis of n = 5,424 pediatric emergency department visits between January 1st and April 19th of 2019 and 2020, and compared healthcare utilization during the pandemic in 2020 to the same period in 2019. RESULTS: In the four weeks after lockdown in Germany began, we observed a massive drop of 63.8% in pediatric emergency healthcare utilization (mean daily visits 26.8 ± SEM 1.5 in 2019 vs. 9.7 ± SEM 1 in 2020, p < 0.005). This drop in cases occurred for both communicable and non-communicable diseases. A larger proportion of patients under one year old (daily mean of 16.6% ±SEM 1.4 in 2019 vs. 23.1% ±SEM 1.7 in 2020, p < 0.01) and of cases requiring hospitalisation (mean of 13.9% ±SEM 1.6 in 2019 vs. 26.6% ±SEM 3.3 in 2020, p < 0.001) occurred during the pandemic. During the analysed time periods, few intensive care admissions and no fatalities occurred. CONCLUSIONS: Our data illustrate a significant decrease in pediatric emergency department visits during the COVID-19 pandemic. Public outreach is needed to encourage parents and guardians to seek medical attention for pediatric emergencies in spite of the pandemic.

An apple a day won't keep the doctor away: presentation, treatment, and outcome in pediatric apple aspirations.

INTRODUCTION: Foreign body (FB) aspiration is a frequent and preventable source of morbidity and mortality, especially in children under 4 years of age. Few comprehensive studies exist on presentation and outcome of apple aspirations in children. METHODS: In a retrospective analysis of bronchoscopy records of a tertiary medical care center from January 2007 to August 2019, we identified pediatric cases of suspected apple aspirations. RESULTS: A total of 11 suspected apple aspirations were identified (observation time 12.7 years, n = 5858 bronchoscopies, n = 226 interventions due to suspected FB aspirations in total). The mean age of patients was 24 months (standard error mean, 7 months; range, 8-83 months), and 6 out of 11 cases (55%) were male. Bronchoscopy confirmed apple aspiration in n = 6/11 cases (55%). In n = 2/11 cases (18%), a bite of the apple was located in the esophagus causing significant tracheal narrowing, and in n = 3/11 cases (27%), no FB was found. In all cases of airway FB identification, extraction was successful. Hypersalivation was associated with esophageal FB location, whereas persistent cough, stridor, or dyspnea were associated with airway FB location. Outcomes ranged from complete reconstitution 1 day after bronchoscopy in most cases to hypoxemia with severe brain damage in one patient. DISCUSSION: This analysis shows that apple aspirations are not entirely uncommon in children and may lead to disastrous complications. Typical signs of airway location are persistent cough, stridor or dyspnea, whereas hypersalivation may point toward an esophageal location. In each case of suspected apple aspiration, timely bronchoscopy with possible FB extraction should be performed by an experienced team.

Glucose Tolerance in Patients with Cystic Fibrosis - Results from the German Cystic Fibrosis Registry.

BACKGROUND: Oral glucose tolerance (OGT) deteriorates progressively in cystic fibrosis (CF). Clinical registries provide a unique basis to study real-world data. PATIENTS & METHODS: OGT tests (OGTTs) documented in the German CF-registry in 2016 were classified according WHO, modified by ADA: normal glucose tolerance (NGT), indeterminate glycaemia (INDET), impaired fasting glucose (IFG), impaired glucose tolerance (IGT), IFG+IGT, diabetes mellitus (DM). To study the association with lung function, multivariable regression adjusted for age, sex, and CFTR mutation was performed. RESULTS: Overall, OGTT screening was done in 35% of CF patients ≧10 years. Of the 996 patients (46.4% females; median age (IQR): 19 (14-27) years) with evaluable OGTTs, 56.2% had either NGT or INDET, whereas 34% had a pre-diabetic OGTT (IFG; IGT; IFG+IGT) and 9.8% a diabetic OGTT. 7 patients had glucose tolerance abnormalities <10 years. DM was more common in females or patients with F508del homozygote mutation, whereas IFG was more frequent in males (all p<0.05). Nearly 75% of patients after transplantation and about half with enteral/parental nutrition and/or steroid use had either a pre-diabetic or diabetic glucose tolerance. In the adjusted model, age (p<0.001) and OGTT category (p=0.013) had both a significant impact on %FEV1. CONCLUSION: Our data of the German CF-registry highlights incidence of glucose tolerance abnormalities in second decade of life in CF patients. However, it also underlines the need for improvement of the documentation and/or performance of OGTT screening in real-world CF care. HINTERGRUND: Bei Mukoviszidose (zystischer Fibrose: CF) verschlechtert sich die orale Glukosetoleranz (OGT) im Krankheitsverlauf. PATIENTEN & METHODEN: OGT Tests (OGTTs), die 2016 im Deutschen CF-Register dokumentiert waren, wurden gemäß WHO (modifiziert nach ADA) kategorisiert: Normale Glukosetoleranz (NGT), intermittierende Glykämie (INDET), eingeschränkte Nüchternglukosetoleranz (IFG), gestörte Glukosetoleranz (IGT), IFG+IGT, Diabetes Mellitus (DM). Um den Zusammenhang mit der Lungenfunktion zu analysieren, wurde eine multivariable Regressionsanalyse adjustiert für Alter, Geschlecht und CFTR Mutation durchgeführt. ERGEBNISSE: Insgesamt wurden 35% der CF-Patienten ≥10 Jahre mittels OGTT gescreent. Von den 996 Patienten (46,4% weiblich, medianes Alter (IQR): 19 (14-27) Jahre) mit auswertbaren OGTTs hatten 56,2% entweder NGT oder INDET, wohingegen bei 34% ein prädiabetischer (IFG; IGT; IFG+IGT) und bei 9,8% ein diabetischer OGTT beobachtet wurde. Bei 7 Patienten zeigten sich vor dem 10. LJ Abnormalitäten im Glukosestoffwechsel. DM war häufiger bei Frauen und Patienten mit homozygoter F508del Mutation, wobei IFG öfters bei Männern vorlag (alle p<0,05). Ca. 75% der Patienten mit Transplantation und etwa die Hälfte der Patienten mit künstlicher Ernährung und/oder Steroidgabe hatten eine prädiabetische oder diabetische Glukosetoleranz. Das Alter (p<0,001) und die OGTT Kategorie (p=0,013) zeigten im adjustierten Modell eine signifikante Assoziation mit %FEV1. SCHLUSSFOLGERUNG: Unsere Daten unterstreichen das Auftreten von Abnormalitäten im Glukosestoffwechsel bei CF im 2. Lebensjahrzehnt. Jedoch weißt es auf die Notwendigkeit eines regelmäßigen Diabetesscreenings und/oder Dokumentation von OGTTs bei CF hin.

Pediatric Healthcare Utilization in a Large Cohort of Refugee Children Entering Western Europe During the Migrant Crisis.

: Background: Currently, half of the population displaced worldwide is children and adolescents. Little is known on healthcare demand in underage migrants. MATERIALS AND METHODS: We analyzed healthcare utilization in n = 1.411 children and adolescents living in a large German refugee reception in 2015-2016. RESULTS: The mean age of all included refugees was 9 years (60.8% male). The majority came from the eastern Mediterranean region. During a mean camp inhabitance of 34 days, 57.6% needed primary healthcare, with a significant inverse correlation of healthcare seeking frequency with age and duration of camp inhabitance. Infants and unaccompanied minors displayed particular high demands for medical help. DISCUSSION: Our analysis showed that pediatric primary healthcare in pediatric and adolescent refugees are most sought during the first period upon arrival with particular demand in infants, toddlers, and unaccompanied minors. Based on this data, future care taking strategies should be adapted accordingly.

Assessment of a Mobile App by Adolescents and Young Adults With Cystic Fibrosis: Pilot Evaluation.

BACKGROUND: Cystic fibrosis (CF) continues to be the most common life-limiting chronic pulmonary disease in adolescents and young adults. Treatment of CF demands a high treatment time investment to slow the progression of lung function decline, the most important contributor to morbidity and mortality. Adherence is challenging in CF due to the high treatment burden and the lack of immediate health consequences in case of nonadherence. Lung function decline is particularly pronounced in the transition phase between 12 and 24 years of age. The improvement of self-management and self-responsibility and independence from parents and desire for normalcy are conflicting aspects for many adolescents with CF, which influence adherence to the time-consuming pulmonary therapy. Mobile health (mHealth) care apps could help to support self-management and independence and thereby reconcile seemingly conflicting goals to improve adherence, quality of life, and ultimately CF life expectancy. OBJECTIVE: This study aimed to (1) assess user behavior and satisfaction among adolescents and young adults with CF over an observation period of three months using an mHealth app; (2) identify areas of improvement for this mHealth app; and (3) compare overall and disease-specific satisfaction, lung function, and anthropometry before and after using the mHealth app. METHODS: A total of 27 adolescents and young adults with CF (age range 12-24 years, mean age 16 years, SD 3 years; 14 females, 11 males) used a free mHealth app for three months of whom 25 provided questionnaire data for analysis at the end of the study. Data collection was carried out using questionnaires on usage characteristics and life satisfaction, and standardized assessment of lung function and anthropometry. RESULTS: The use of the reminder function for medication declined from 70% (15/21) of the participants at week 4 to 65% (13/20) at week 8 of the observation period. At the end of the study, only 17% (4/23) of the participants wanted to continue using the app. Nevertheless, 56% (14/25) of participants saw the mobile app as a support for everyday life. Potential improvements targeting hedonistic qualities were identified to improve mHealth app adherence. Comparisons of satisfaction with different life aspects hinted at improvements or stabilization for the subitem respiration and the subitem lack of handicap by CF, suggesting that app use might stabilize certain CF-specific aspects of the weighted satisfaction with life. Lung function and anthropometry were not affected consistently. CONCLUSIONS: Most of the patients did not want to continue using the app after the study period. Only a few CF-specific aspects of weighted life satisfaction were possibly stabilized by the mHealth app; clinical parameters were not affected. Adaptation of the functions to adolescent-specific needs could improve the long-term use and thus positively affect the disease course.

Preventive Inhalation of Hypertonic Saline in Infants with Cystic Fibrosis (PRESIS). A Randomized, Double-Blind, Controlled Study.

Rationale: Cystic fibrosis (CF) lung disease starts in early infancy, suggesting that preventive treatment may be most beneficial. Lung clearance index (LCI) and chest magnetic resonance imaging (MRI) have emerged as promising endpoints of early CF lung disease; however, randomized controlled trials testing the safety and efficacy of preventive therapies in infants with CF are lacking. Objectives: To determine the feasibility, safety, and efficacy of preventive inhalation with hypertonic saline (HS) compared with isotonic saline (IS) in infants with CF, including LCI and MRI as outcome measures. Methods: In this randomized, double-blind, controlled trial, 42 infants with CF less than 4 months of age were randomized across five sites to twice-daily inhalation of 6% HS (n = 21) or 0.9% IS (n = 21) for 52 weeks. Measurements and Main Results: Inhalation of HS and IS was generally well tolerated by infants with CF, and the number of adverse events did not differ between groups (P = 0.49). The change in LCI from baseline to Week 52 was larger in infants with CF treated with HS (-0.6) than in those treated with IS (-0.1; P < 0.05). In addition, weight gain was improved in infants with CF treated with HS (P < 0.05), whereas pulmonary exacerbations and chest MRI scores did not differ in the HS group versus the IS group. Conclusions: Preventive inhalation with HS initiated in the first months of life was safe and well tolerated and resulted in improvements in LCI and weight gain in infants with CF. Our results support the feasibility of LCI as an endpoint in randomized controlled trials in infants with CF. Clinical trial registered with www.clinicaltrials.gov (NCT01619657).

Healthcare Utilization in a Large Cohort of Asylum Seekers Entering Western Europe in 2015.

During the current period of immigration to Western Europe, national healthcare systems are confronted with high numbers of asylum seekers with largely unknown health status. To improve care taking strategies, we assessed healthcare utilization in a large, representative cohort of newly arriving migrants consisting of n = 1533 residents of a reception center in Northern Germany in 2015. Most asylum seekers were young, male adults, and the majority came from the Eastern Mediterranean region. Overall, we observed a frequency of 0.03 visits to the onsite primary healthcare ward per asylum seeker and day of camp residence (IQR 0.0⁻0.07, median duration of residence 38.0 days, IQR 30.0⁻54.25). Female asylum seekers showed higher healthcare utilization rates than their male counterparts, and healthcare utilization was particularly low in asylum seekers in their second decade of life. Furthermore, a significant correlation between time after camp entrance and healthcare utilization behavior occurred: During the first week of camp residence, 37.1 visits/100 asylum seekers were observed, opposed to only 9.5 visits/100 asylum seekers during the sixth week of camp residence. This first data on healthcare utilization in a large, representative asylum seeker cohort entering Western Europe during the current crisis shows that primary care is most needed in the first period directly after arrival. Our dataset may help to raise awareness for refugee and migrant healthcare needs and to adapt care taking strategies accordingly.
