Time course of antipsychotic treatment response in schizophrenia: Results from a naturalistic study in 280 patients

2010

To describe the course of positive and negative symptoms during inpatient treatment and examine remission and response rates under routine clinical care conditions.Two hundred and eighty inpatients with schizophrenia (DSM-IV criteria) were assessed with the Positive and Negative Syndrome Scale (PANSS) at admission and at biweekly intervals until discharge from hospital. Remission was defined according to the symptom-severity component of the consensus criteria (Remission in Schizophrenia Working Group) as a rating of three or less in the relevant PANSS items at discharge, and response as a reduction of at least 20% in the PANSS total score from admission to discharge.The mean duration of in…

The time course of orthography and phonology: ERP correlates of masked priming effects in Spanish

2009

Abstract One key issue for computational models of visual-word recognition is the time course of orthographic and phonological information during reading. Previous research, using both behavioral and event related brain potential (ERP) measures, has shown that orthographic codes are activated very early but that phonological activation starts to occur immediately afterward. Here we report an ERP masked priming experiment in Spanish that investigates this issue further by using very strict control conditions. The critical phonological comparison was between two pairs of primes having the same orthographic similarity to the target words but differing in phonological similarity (e.g., conal-CA…

The time course of face matching for featural and relational image manipulations

2011

It was found recently that horizontal and vertical relationships of facial features are differently vulnerable to inversion (Goffaux & Rossion, 2007). When faces are upside down manipulations of vertical relations are difficult to detect, while only moderate performance deficits are found for manipulations of horizontal relations, or when features differ. We replicate the findings of Goffaux and Rossion, and record the temporal courses of face matching performance and the effects of inversion. For vertical relations and featural changes inversion effects arise immediately, starting with the first 50 ms of processing. For horizontal relations inversion effects are absent at brief timings, bu…

A 12-month Prospective Study of Tear Osmolarity in Contact Lens Wearers Refitted with Daily Disposable Soft Contact Lenses

2020

SIGNIFICANCE Tear osmolarity has been reported as one of the best diagnostic tests for dry eye disease and its management. Contact lens wear is thought to influence tear homeostasis. Understanding how regular wear of contact lenses and their type affect tear osmolarity is important. PURPOSE The purpose of this study was to assess changes in tear osmolarity and ocular symptoms over a period of 12 months following refitting contact lens wearers with daily disposable contact lenses. METHODS Fifty subjects aged (mean ± SD) 26 ± 4 years were refitted with either silicone-hydrogel (delefilcon A, SiHy, n = 34) or hydrogel (omafilcon A, Hy, n = 16) daily disposable soft contact lenses. Study includ…

ERP correlates of masked affective priming with emoticons

2013

Emoticons seem to enrich computer-mediated communication by improving enjoyment, perceived richness and usefulness of information (Huang, Yen, & Zhang, 2008). Despite their extensive use over the last decades, the way emoticons affect subsequent emotional/cognitive processing is not fully understood. Here we conducted a masked priming experiment that explored the time course of the masked affective priming effect while recording event-related potentials. Type of prime (emoticon vs. word) and prime valence (positive vs. negative) were manipulated to assess their influence in the processing of positive/negative target words. Results showed a masked affective priming effect in early (N2) and l…

État des lieux et évaluation de la surveillance des Staphylococcus aureus résistants à la méticilline (SARM) : PMSI versus surveillance Raisin

2013

Abstract Background The surveillance of methicillin-resistant Staphylococcus aureus (MRSA) is a national priority. The rate of MRSA infections is one of six indicators tracked by the Department of Health. Since 2002, the French institute for public health surveillance (InVS) has monitored MRSA infections to estimate incidence density. Today, the use of the French administrative database (PMSI) could facilitate this surveillance. The aim of this study was to compare MRSA incidence density computed at a national level using PMSI databases with the results from the InVS taken as the reference. Methods PMSI databases for the years 2006 to 2009 were used. The reference results were those publish…

The processing of consonants and vowels during letter identity and letter position assignment in visual-word recognition: an ERP study.

2009

Abstract Recent research suggests that there is a processing distinction between consonants and vowels in visual-word recognition. Here we conjointly examine the time course of consonants and vowels in processes of letter identity and letter position assignment. Event related potentials (ERPs) were recorded while participants read words and pseudowords in a lexical decision task. The stimuli were displayed under different conditions in a masked priming paradigm with a 50-ms SOA: (i) identity/baseline condition e.g., chocolate-CHOCOLATE); (ii) vowels-delayed condition (e.g., choc l te-CHOCOLATE); (iii) consonants-delayed condition (cho o ate-CHOCOLATE); (iv) consonants-transposed condition (…

The use of texture analysis to study the time course of chromatolysis

1998

Image analysis of the textural feature entropy of the Nissl substance was used to monitor the time course of chromatolysis in regenerating hypoglossal motoneurons and degenerating facial motoneurons 4-112 days after hypoglossal-facial anastomosis in rats. Changes in the Nissl substance were detected that were not obvious on the basis of subjective judgement of the light-microscopical appearance of the neurons. Chromatolysis started 4 days post operation (dpo) and was not reversed at 112 dpo in both nuclei. The increase of chromatolysis was 14-28 dpo faster in the regenerating hypoglossal neurons than in degenerating facial neurons. Maximal chromatolysis was measured at 56-70 dpo in both nuc…
