- Lung infections with Mycobacterium abscessus, a species of multidrug-resistant nontuberculous mycobacteria, are emerging as an important global threat to individuals with cystic fibrosis (CF), in whom M. abscessus accelerates inflammatory lung damage, leading to increased morbidity and mortality. Previously, M. abscessus was thought to be independently acquired by susceptible individuals from the environment. However, using whole-genome analysis of a global collection of clinical isolates, we show that the majority of M. abscessus infections are acquired through transmission, potentially via fomites and aerosols, of recently emerged dominant circulating clones that have spread globally. We demonstrate that these clones are associated with worse clinical outcomes, show increased virulence in cell-based and mouse infection models, and thus represent an urgent international infection challenge.

- 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 (5.222.3) 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.

- A taskforce formed in 2013 by the International Federation of Clinical Neurophysiology developed an EEG terminology with international consensus. In the following, the result - the second version of Standardized Computer-based Organized Reporting of EEG (SCORE) will be summarised. The terminology was tested in clinical practice using a software package (SCORE-EEG) applied to over 12,000 EEGs. The selection of terms is context-dependent: the initial selection determines which further options are available. A report is automatically generated and individual features are fed into a database. SCORE contains specialised modules for reporting on epileptic seizures, as well as for characteristic neonatal and intensive care EEG features. SCORE is a useful tool not only for outpatient, clinical and research settings, but also for quality control, data sharing and education.

- Introduction Multiple breath washout (MBW) is used for early detection of cystic fibrosis (CF) lung disease, with SF6MBW commonly viewed as the reference method. The use of N2MBW in infants and toddlers has been questioned for technical and physiological reasons, but a new correction of the N(2 )signal has minimized the technical part. The present study aimed to assess the remaining differences and the contributing mechanisms for the differences between SF6 and N2MBW,corrected-such as tidal volume reduction during N-2 washout with pure O-2. Method This was a longitudinal multicenter cohort study. SF6MBW and N2MBW were performed prospectively at three CF centers in the same visits on 154 test occasions across 62 children with CF (mean age: 22.7 months). Offline analysis using identical algorithms to the commercially available program provided outcomes of N-2,N-original and N-2,N-corrected for comparison with SF6MBW. Results Mean functional residual capacity, FRCN2,corrected was 14.3% lower than FRCN2, original, and 1.0% different from FRCSF6. Lung clearance index, LCIN2,corrected was 25.2% lower than LCIN2,original, and 7.3% higher than LCISF6. Mean (SD) tidal volume decreased significantly during N2MBWcorrected, compared to SF6MBW (-13.1 ml [-30.7; 4.6], p < 0.0001, equal to -12.0% [-25.7; 1.73]), but this tidal volume reduction did not correlate to the differences between LCIN2,corrected and LCISF6. The absolute differences in LCI increased significantly with higher LCISF6 (0.63/LCISF6) and (0.23/LCISF6), respectively, for N-2,N-original and N-2,N-corrected, but the relative differences were stable across disease severity for N-2,N-corrected, but not for N-2,N-original. Conclusion Only minor residual differences between FRCN2,corrected and FRCSF6 remained to show that the two methods measure gas volumes very similar in this age range. Small differences in LCI were found. Tidal volume reduction during N2MBW did not affect differences. The corrected N2MBW can now be used with confidence in young children with CF, although not interchangeably with SF6.

- There is currently no international consensus procedure for performing comprehensive periictal testing of patients in the epilepsy monitoring units (EMUs). Our primary goal was to develop a standardized procedure for managing and testing patients during and after seizures in EMUs. The secondary goal was to assess whether it could be implemented in clinical practice (feasibility). A taskforce was appointed by the International League Against Epilepsy (ILAE)—Commission on European Affairs and the European Epilepsy Monitoring Unit Association, to develop a standardized ictal testing battery (ITB) based on expert opinion and experience with various local testing protocols. ITB contains a comprehensive set of 10 items that evidence the clinically relevant semiologic features, and it is adaptive to the dynamics of the individual seizures. The feasibility of the ITB was prospectively evaluated on 250 seizures from 152 consecutive patients in 10 centers. ITB was successfully implemented in clinical practice in all 10 participating centers and was considered feasible in 93% of the tested seizures. ITB was not feasible for testing seizures of very short duration. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy
