Assessing attention allocation toward threat-related stimuli: a comparison of the emotional Stroop task and the attentional probe task

2003

This study examined the association of two widely used measures of attention allocation toward or away from threat-related stimuli: The emotional Stroop task and the attentional probe task. Fifty-three participants responded to computer versions of both tasks where stimuli were presented both subliminally and supraliminally. Thus, four indexes indicating attention allocation were computed for each participant. A correlation analysis showed that the attentional probe index and the emotional Stroop index were associated within each presentation mode while all other relations were nonsignificant. These results are discussed in terms of a distinction between preattentive and attentional process…

Traditional Chinese medicine research in the post-genomic era: good practice, priorities, challenges and opportunities.

2012

Abstract Background and aims GP-TCM is the 1st EU-funded Coordination Action consortium dedicated to traditional Chinese medicine (TCM) research. This paper aims to summarise the objectives, structure and activities of the consortium and introduces the position of the consortium regarding good practice, priorities, challenges and opportunities in TCM research. Serving as the introductory paper for the GP-TCM Journal of Ethnopharmacology special issue, this paper describes the roadmap of this special issue and reports how the main outputs of the ten GP-TCM work packages are integrated, and have led to consortium-wide conclusions. Materials and methods Literature studies, opinion polls and di…

Current research demonstrates beneficial effects of physical activity on brain functions and cognitive performance. To date, less is known on the effects of gross motor movements that do not fall into the category of sports-related aerobic or anaerobic exercise. In previous studies, we found beneficial effects of dynamic working environments, i.e., environments that encourage movements during cognitive task performance, on cognitive performance and corresponding brain activity. Aim of the present study was to examine the effects of working in a dynamic and a static office environment on attentional and vigilance performance, and on the corresponding electroencephalographic (EEG) brain oscil…

Force Control and Motor Unit Firing Behavior Following Mental Fatigue in Young Female and Male Adults

2020

Purpose: The neuromuscular mechanisms leading to impaired motor performance in the presence of mental fatigue remain unclear. It is also unknown if mental fatigue differentially impacts motor performance in males and females. The purpose of this study was to assess the impact of mental fatigue on force production and motor unit (MU) firing behavior in males and females. Methods: Nineteen participants performed 10-s isometric dorsiflexion (DF) contractions at 20 and 50% maximum voluntary contraction (MVC) before, during, and after completing 22 min of the psychomotor vigilance task (PVT), to induce mental fatigue. The DF force and indwelling MU firing behavior of the tibialis anterior (TA) w…

Local Sleep Slow-Wave Activity Colocalizes With the Ictal Symptomatogenic Zone in a Patient With Reflex Epilepsy

2020

Background: Slow-wave activity (SWA) during non-rapid eye movement (NREM) sleep reflects synaptic potentiation during preceding wakefulness. Epileptic activity may induce increases in state-dependent SWA in human brains, therefore, localization of SWA may prove useful in the presurgical workup of epileptic patients. We analyzed high-density electroencephalography (HDEEG) data across vigilance states from a reflex epilepsy patient with a clearly localizable ictal symptomatogenic zone to provide a proof-of-concept for the testability of this hypothesis. Methods: Overnight HDEEG recordings were obtained in the patient during REM sleep, NREM sleep, wakefulness, and during a right facial motor s…

Digoxin-related leukocytoclastic vasculitis in a very elderly woman: A case report

2016

International audience; Even though digoxin causes many side effects, few cases of skin involvement are recorded in the French Pharmacovigilance Database. We report a case of leukocytoclastic vasculitis (LV) very probably due to digoxin. A 91-year-old woman, hospitalized following a fall, presented cardiac decompensation in a context of rapid atrial fibrillation requiring treatment with digoxin. Eight days later, a rash appeared on her back and trunk. It was neither itchy, nor painful and persisted despite local treatment. There were no other clinical anomalies. After a few days, the rash spread with appearance of bullous lesions, ulcerations and a necrosis on lymphedema of the two legs. Am…

Antibiotic prophylaxis for the prevention of infective endocarditis for dental procedures is not associated with fatal adverse drug reactions in Fran…

2018

Background One of the major reasons to stop antibiotic prophylaxis (AP) to prevent infective endocarditis (IE) in the United Kingdom but not in the rest of the world was that it would result in more deaths from fatal adverse drug reactions (ADRs) than the number of IE deaths. The main aim of this study was to quantify and describe the ADRs with amoxicillin or clindamycin for IE AP. The second aim was to infer a crude incidence of anaphylaxis associated with amoxicillin for IE AP. Material and Methods The Medical Dictionary for Regulatory Activities (MedDRA) was used to group ADRs for IE AP using the broad Standardized MedDRA Queries “Anaphylactic reaction, Amoxicillin, Clindamycin, Clostrid…

Immune Checkpoint Inhibitors and Cardiotoxicity: An Analysis of Spontaneous Reports in Eudravigilance

2021

Introduction Immune checkpoint inhibitors (ICIs) are widely used in the treatment of many cancers as they improve clinical outcomes. However, ICIs have also been associated with the development of immune-related adverse drug reactions (ADRs). Among immune-related ADRs, cardiac immune-related ADRs are rare, but also associated with high mortality rates. Objective The objective of this study was to evaluate the occurrence of cardiac ADRs reported with ICIs in the European spontaneous reporting system. Methods We retrieved individual case safety reports on ICI-induced cardiac ADRs from the website of suspected ADR (www.adrreports.eu) of the European pharmacovigilance database (Eudravigilance).…

Drug-Induced Liver Injury Associated With Antidepressive Psychopharmacotherapy: An Explorative Assessment Based on Quantitative Signal Detection Usin…

2015

Drug-induced liver injury is a major problem of pharmacotherapy and is also frequent with antidepressive psychopharmacotherapy. However, there are only few studies using a consistent methodologic approach to study hepatotoxicity of a larger group of antidepress ants. We performed a quantitative signal detection analysis using data from the Uppsala Monitoring Centre from the WHO that records adverse drug reaction (ADR) data from worldwide sources; we retrieved substance- and country-specific (Australia, France, Germany, Italy, Spain, the United Kingdom, and the United States) ADR data and calculated reporting odds ratios as measures for disproportionality within a case/noncase approach. To a…

[Adverse reactions to human papillomavirus vaccine in the Valencian Community (2007-2011)].

2014

Introduction: In 2009, two cases of seizures in adolescents following quadrivalent human papillomavirus vaccine (qHPV) administration generated important media attention, and adversely affected public trust in this vaccine. Our objectives were to describe suspected adverse reactions (SARs) reported to the Pharmacovigilance Centre in the Valencian Community (PCVC) after administration of HPV vaccine, and to compare reporting rates of syncope and seizures following this vaccine with those of other vaccines administered to girls aged 13–15 years. Materials and methods: Descriptive study of SARs reported following administration of this vaccine to the PCVC between 2007 and 2011. Results: The cl…
