- Purpose: Epilepsy patients consider driving issues to be one of their most serious concerns. Ideally, decisions regarding fitness to drive should be based upon thorough evaluations by specialists in epilepsy care. In 2009, an EU directive was published aiming to harmonize evaluation practices within European countries, but, despite these recommendations, whether all epileptologists use the same criteria is unclear. We therefore conducted this study to investigate routine practices on how epileptologists at European epilepsy centers evaluate fitness to drive. Methods: A questionnaire was sent to 63 contact persons identified through the European Epi-Care and the Epilepsy network. The questionnaire addressed how fitness-to-drive evaluations were conducted, the involvement of different professionals, the use and interpretation of EEG, and opinions on existing regulations and guidelines. Results: The questionnaire was completed by 35 participants (56 % response rate). Results showed considerable variation regarding test routines and the emphasis placed on the occurrence and extent of epileptiform discharges revealed by EEG. 82 % of the responders agreed that there was a need for more research on how to better evaluate fitness-to-drive in people with epilepsy, and 89 % agreed that regulations on fitness to drive evaluations should be internationally coordinated. Conclusion: Our survey showed considerable variations among European epileptologists regarding use of EEG and how findings of EEG pathology should be assessed in fitness-to-drive evaluations. There is a clear need for more research on this issue and international guidelines on how such evaluations should be carried out would be of value.

- PURPOSE: In the context of sarcoidosis, lung transplantation is often performed in patients with irreversible advanced lung disease unresponsive to medical therapy. The clinical phenotypes and posttransplant survival remain unclear, due primarily to the recurring nature of the disease and extrapulmonary involvement. The objective of this study in a large multicenter European cohort was to describe the clinical characteristics and outcomes of patients with pulmonary sarcoidosis treated by lung transplantation. METHODS: We retrospectively reviewed the data of 147 patients with pulmonary sarcoidosis who underwent lung or heart-lung transplantation between 1990 and 2019 at 15 European centers. Inclusion criteria were sarcoidosis meeting international diagnostic criteria and availability of data from pretransplantation right heart catheterization, lung function testing, and chest computed tomography (CT) staged using a standardized system. RESULTS: At transplantation, mean age was 50±8 years, 62% were male, and 20% had extrapulmonary manifestations. Mean values before transplantation were as follows: FVC (%pred), 46±17%; FEV1 (%pred), 38±19; FVC/FEV1 (%), 55±32; DLCO (%pred), 31±13; mPAP (mmHg), 36±13; PCWP (mmHg), 10±5; cardiac index (L/min/m²), 3.0±0.8; and pulmonary vascular resistance (dyn·s·cm-5), 480±340; furthermore, 60% of patients had severe pulmonary hypertension. Posttransplant survival rates after 1, 3, and 5 years were 85%, 69%, and 63%, respectively. During the median [range] follow-up of 43 [17-79] months, 38% of patients developed chronic lung allograft dysfunction. Factors significantly associated with outcomes were high emergency transplantation, era of transplantation, preoperative extrapulmonary sarcoidosis, and extent of fibrosis by CT. CONCLUSION: Posttransplant survival rates and freedom from chronic lung allograft dysfunction in patients with pulmonary sarcoidosis were similar to those in patients with other reasons for lung transplantation. Factors associated with worse outcomes were high emergency transplantation, earlier transplantation era, preoperative extrapulmonary sarcoidosis, and greater burden of fibrosis by CT.

- Introduction We examine the role of brain apolipoprotein B (apoB) as a putative marker of early tau pathology and cognitive decline. Methods Cerebrospinal fluid (CSF) samples from cognitively normal and Alzheimer's disease (AD) participants were collected to measure protein levels of apoB and AD biomarkers amyloid beta (A beta), t-tau and p-tau, as well as synaptic markers GAP43, SYNAPTOTAGMIN-1, synaptosome associated protein 25 (SNAP-25), and NEUROGRANIN. CSF apoB levels were contrasted with positron emission tomography (PET) scan measures of A beta (18F-NAV4694) and Tau (flortaucipir) along with cognitive assessment alterations over 6 to 8 years. Results CSF apoB levels were elevated in AD participants and correlated with t-tau, p-tau, and the four synaptic markers in pre-symptomatic individuals. In the latter, CSF apoB levels correlated with PET flortaucipir-binding in entorhinal, parahippocampal, and fusiform regions. Baseline CSF apoB levels were associated with longitudinal visuospatial cognitive decline. Discussion CSF apoB markedly associates with early tau dysregulation in asymptomatic subjects and identifies at-risk individuals predisposed to develop visuospatial cognitive decline over time.

- We present a novel chemical database for gas-phase astrochemistry. Named the KInetic Database for Astrochemistry (KIDA), this database consists of gas-phase reactions with rate coefficients and uncertainties that will be vetted to the greatest extent possible. Submissions of measured and calculated rate coefficients are welcome, and will be studied by experts before inclusion into the database. Besides providing kinetic information for the interstellar medium, KIDA is planned to contain such data for planetary atmospheres and for circumstellar envelopes. Each year, a subset of the reactions in the database (kida.uva) will be provided as a network for the simulation of the chemistry of dense interstellar clouds with temperatures between 10 K and 300 K. We also provide a code, named Nahoon, to study the time-dependent gas-phase chemistry of zero-dimensional and one-dimensional interstellar sources.

- Objective: To define benchmark cutoffs for redo liver transplantation (redo-LT). Background: In the era of organ shortage, redo-LT is frequently discussed in terms of expected poor outcome and wasteful resources. However, there is a lack of benchmark data to reliably evaluate outcomes after redo-LT. Methods: We collected data on redo-LT between January 2010 and December 2018 from 22 high-volume transplant centers. Benchmark cases were defined as recipients with model of end stage liver disease (MELD) score <= 25, absence of portal vein thrombosis, no mechanical ventilation at the time of surgery, receiving a graft from a donor after brain death. Also, high-urgent priority and early redo-LT including those for primary nonfunction (PNF) or hepatic artery thrombosis were excluded. Benchmark cutoffs were derived from the 75th percentile of the medians of all benchmark centers. Results: Of 1110 redo-LT, 373 (34%) cases qualified as benchmark cases. Among these cases, the rate of postoperative complications until discharge was 76%, and increased up to 87% at 1-year, respectively. One-year overall survival rate was excellent with 90%. Benchmark cutoffs included Comprehensive Complication Index CCI (R) at 1-year of <= 72, and in-hospital and 1-year mortality rates of <= 13% and <= 15%, respectively. In contrast, patients who received a redo-LT for PNF showed worse outcomes with some values dramatically outside the redoLT benchmarks. Conclusion: This study shows that redo-LT achieves good outcome when looking at benchmark scenarios. However, this figure changes in high-risk redo-LT, as for example in PNF. This analysis objectifies for the first-time results and efforts for redo-LT and can serve as a basis for discussion about the use of scarce resources.

- INTRODUCTION Measuring day-to-day sleep variability might reveal unstable sleep-wake cycles reflecting neurodegenerative processes. We evaluated the association between Alzheimer's disease (AD) fluid biomarkers with day-to-day sleep variability. METHODS In the PREVENT-AD cohort, 203 dementia-free participants (age: 68.3 +/- 5.4; 78 males) with a parental history of sporadic AD were tested with actigraphy and fluid biomarkers. Day-to-day variability (standard deviations over a week) was assessed for sleep midpoint, duration, efficiency, and nighttime activity count. RESULTS Lower cerebrospinal fluid (CSF) ApoE, higher CSF p-tau181/amyloid-beta (A beta)(42), and higher plasma p-tau231/A beta(42) were associated with higher variability of sleep midpoint, sleep duration, and/or activity count. The associations between fluid biomarkers with greater sleep duration variability were especially observed in those that carried the APOE4 allele, mild cognitive impairment converters, or those with gray matter atrophy. DISCUSSION Day-to-day sleep variability were associated with biomarkers of AD in at-risk individuals, suggesting that unstable sleep promotes neurodegeneration or, conversely, that AD neuropathology disrupts sleep-wake cycles.
