Methylphenidate, modafinil, and caffeine for cognitive enhancement in chess: A double-blind, randomised controlled trial.

Stimulants and caffeine have been proposed for cognitive enhancement by healthy subjects. This study investigated whether performance in chess - a competitive mind game requiring highly complex cognitive skills - can be enhanced by methylphenidate, modafinil or caffeine. In a phase IV, randomized, double-blind, placebo-controlled trial, 39 male chess players received 2×200mg modafinil, 2×20mg methylphenidate, and 2×200mg caffeine or placebo in a 4×4 crossover design. They played twenty 15-minute games during two sessions against a chess program (Fritz 12; adapted to players' strength) and completed several neuropsychological tests. Marked substance effects were observed since all three subs…

Randomized controlled study of early medication change for non-improvers to antidepressant therapy in major depression – The EMC trial

Patients with Major Depressive Disorder (MDD) and no improvement after two weeks of antidepressant pharmacotherapy have a high risk of treatment failure. The aim of the study was to determine whether an early medication change (EMC) strategy is superior to a guideline-based treatment in MDD patients without improvement after two weeks of antidepressant pharmacotherapy. Eight-hundred-and-eighty-nine patients with MDD were enrolled, 879 patients received the SSRI escitalopram. Of those, 192 patients had no improvement, defined as a reduction of < 20% on the Hamilton Depression Rating Scale (HAMD-17) after 14 days of treatment, and were randomly assigned to open treatment with the EMC strategy…

W05-01 - Rationale and Design of an RCT Comparing “EMC-Strategy” with TAU in Patients with Major Depression - the EMC Trial

IntroductionFor Major Depression, current guidelines recommend treatment durations of 3-8 weeks until optimisation in case of insufficient outcome. Many retrospective studies indicate that improvement (HAMD-17 decrease ≥20%) occurs usually within 10-14 days and that non-improvement after 14 days of treatment is highly predictive for poor clinical outcome.MethodsIn level 1 of the EMC trial, non-improvers after 14 days of antidepressant treatment will be randomised to “early medication change” (EMC) strategy or treatment according to current guidelines (TAU). EMC schedules treatment optimisations on day 15 and day 29 in case of non-improvement. TAU schedules a medication change after 28 days …

Effect of high-caloric nutrition on serum neurofilament light chain levels in amyotrophic lateral sclerosis

Recent publications showed that circulating neurofilaments (Nfs) may be used as a diagnostic biomarker distinguishing amyotrophic lateral sclerosis (ALS) from ALS mimics with high sensitivity and specificity.1–3 Furthermore, it has been shown that patients with higher Nf levels show faster disease progression1 and shorter survival.2 3 Nf levels remain rather stable during the course of disease.2 Current literature suggests that the diagnostic value of neurofilament light chains (NfL) and phosphorylated neurofilament heavy chains in cerebrospinal fluid is about equal, whereas in blood NfL seems to be superior.4 In this study, we investigated the effect of a high-caloric fatty diet (HCFD) on …

Early switch to oral anticoagulation in patients with acute intermediate-risk pulmonary embolism (PEITHO-2) : a multinational, multicentre, single-arm, phase 4 trial

BACKGROUND: Current guidelines recommend a risk-adjusted treatment strategy for the management of acute pulmonary embolism. This is a particular patient category for whom optimal treatment (anticoagulant treatment, reperfusion strategies, and duration of hospitalisation) is currently unknown. We investigated whether treatment of acute intermediate-risk pulmonary embolism with parenteral anticoagulation for a short period of 72 h, followed by a switch to a direct oral anticoagulant (dabigatran), is effective and safe. METHODS: We did a multinational, multicentre, single-arm, phase 4 trial at 42 hospitals in Austria, Belgium, France, Germany, Italy, Netherlands, Romania, Slovenia, and Spain. …

Effect of High‐Caloric Nutrition on Survival in Amyotrophic Lateral Sclerosis

International audience; Objective: Weight loss has been identified as a negative prognostic factor in amyotrophic lateral sclerosis, but there is no evidence regarding whether a high-caloric diet increases survival. Therefore, we sought to evaluate the efficacy of a high-caloric fatty diet (HCFD) for increasing survival.Methods: A 1:1 randomized, placebo-controlled, parallel-group, double-blinded trial (LIPCAL-ALS study) was conducted between February 2015 and September 2018. Patients were followed up at 3, 6, 9, 12, 15, and 18 months after randomization. The study was performed at 12 sites of the clinical and scientific network of German motor neuron disease centers (ALS/MND-NET). Eligible…
