Psychometric Assessment of an Item Bank for Adaptive Testing on Patient-Reported Experience of Care Environment for Severe Mental Illness: Validation Study.

Background: The care environment significantly influences the experiences of patients with severe mental illness and the quality of their care. While a welcoming and stimulating environment enhances patient satisfaction and health outcomes, psychiatric facilities often prioritize staff workflow over patient needs. Addressing these challenges is crucial to improving patient experiences and outcomes in mental health care.

Development of the PREMIUM computerized adaptive testing for measuring the access and care coordination for patients with severe mental illness.

Severe mental illness (SMI) patients often have complex health needs, which makes it difficult to access and coordinate their care. This study aimed to develop a computerized adaptive testing (CAT) tool, PREMIUM CAT-ACC, to measure SMI patients' experience with access and care coordination. This multicenter and cross-sectional study included 496 adult in- and out-patients with SMI (i.

Digital Phenotyping for Differential Diagnosis of Major Depressive Episode: Narrative Review.

Background: Major depressive episode (MDE) is a common clinical syndrome. It can be found in different pathologies such as major depressive disorder (MDD), bipolar disorder (BD), posttraumatic stress disorder (PTSD), or even occur in the context of psychological trauma. However, only 1 syndrome is described in international classifications (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition [DSM-5]/International Classification of Diseases 11th Revision [ICD-11]), which do not take into account the underlying pathology at the origin of the MDE.

Medications as a Trigger of Sleep-Related Eating Disorder: A Disproportionality Analysis.

Sleep-related eating disorder (SRED) is a parasomnia with recurrent, involuntary, amnestic eating episodes during sleep. There is growing evidence of the association between SRED and medications. Therefore, we aimed to rank drugs showing the strongest association.

COVID-19 Vaccine-Associated Transient Global Amnesia: A Disproportionality Analysis of the WHO Safety Database.

Coronavirus disease 2019 (COVID-19) spread rapidly, resulting in a global pandemic for which vaccines were quickly developed. As their safety continues to be monitored, cases of transient global amnesia (TGA) following mRNA vaccination with elasomeran have been reported. TGA is characterized by sudden onset of anterograde amnesia with preservation of other cognitive functions and resolution within 24 h.

Personality Related to Quality-of-Life Improvement After Deep Brain Stimulation in Parkinson's Disease (PSYCHO-STIM II).

Background: Deep brain stimulation of the sub-thalamic nucleus (DBS-STN) reduces symptoms in Parkinson's disease (PD) patients with motor fluctuations. However, some patients may not feel ameliorated afterwards, despite an objective motor improvement. It is thus important to find new predictors of patients' quality of life (QoL) amelioration after DBS-STN.

Functional and dysfunctional impulsivities changes after subthalamic nucleus-deep brain stimulation in Parkinson disease.

Objectives: We investigated changes of impulsivity after deep brain stimulation (DBS) of the subthalamic nucleus (STN) in Parkinson's disease (PD) patients, distinguishing functional from dysfunctional impulsivity and their contributing factors.

Methods: Data of 33 PD patients treated by STN-DBS were studied before and 6 months after surgery: motor impairment, medication (dose and dopaminergic agonists), cognition, mood and occurrence of impulse control disorders. Impulsivity was assessed by the Dickman Impulsivity Inventory, which distinguishes functional impulsivity (FI), reflecting the potential for reasoning and rapid action when the situation requires it, and dysfunctional impulsivity (DI), reflecting the lack of prior reasoning, even when the situation demands it.

Personality dimensions of patients can change during the course of parkinson's disease.

Background: Studies assessing personality dimensions by the "Temperament and Character Inventory" (TCI) have previously found an association between Parkinson's disease (PD) and lower Novelty Seeking and higher Harm Avoidance scores. Here, we aimed to describe personality dimensions of PD patients with motor fluctuations and compare them to a normative population and other PD populations.

Methods: All PD patients awaiting Deep Brain Stimulation (DBS) answered the TCI before neurosurgery.

Anterior pallidal deep brain stimulation for Tourette's syndrome: a randomised, double-blind, controlled trial.

Background: Deep brain stimulation (DBS) has been proposed to treat patients with severe Tourette's syndrome, and open-label trials and two small double-blind trials have tested DBS of the posterior and the anterior internal globus pallidus (aGPi). We aimed to specifically assess the efficacy of aGPi DBS for severe Tourette's syndrome.

Methods: In this randomised, double-blind, controlled trial, we recruited patients aged 18-60 years with severe and medically refractory Tourette's syndrome from eight hospitals specialised in movement disorders in France.

Midgut microbiota and host immunocompetence underlie Bacillus thuringiensis killing mechanism.

Bacillus thuringiensis is a widely used bacterial entomopathogen producing insecticidal toxins, some of which are expressed in insect-resistant transgenic crops. Surprisingly, the killing mechanism of B. thuringiensis remains controversial.

[Negative symptoms of schizophrenia: historical aspects].

The history of negative symptoms of schizophrenia rises early days of medicine in clinical and pathophysiological differences between positive and negative and their complex joint. Forming a set of typical core of symptoms, and some feature of a syndrome belonging to a specific pathophysiological mechanism, negative symptoms of schizophrenia emerge from old descriptions of clinical pictures, related to the overall look of madness, the heart of alienation, a central sign of early dementia, gradually more precisely describing the strange nature of the autistic withdrawal and schizophrenic apragmatism. At therapeutic era, negative symptoms have taken over the positive symptoms to establish an operational criteria whose importance lies in the progressive severity of this clinical type and in their contribution to therapeutic resistance.

[Comorbidity of affective disorders and alcohol use disorder].

The comorbidity of affective disorders with alcohol use disorder remains insufficiently taken into account. In spite of the well-known frequency of the addict comorbidity in most psychiatric disorders, the level of association between affective disorders and alcohol is still underestimated and poorly understood. The label of "double diagnosis" relates to a simple addition of two independent pathologies.

Limbic versus cognitive target for deep brain stimulation in treatment-resistant depression: accumbens more promising than caudate.

High-frequency deep brain stimulation (DBS) represents a major stake for treatment for treatment-resistant depression (TRD). We describe a preliminary trial of DBS of two potential brain targets in chronic TRD: the nucleus accumbens (Acb) and, in the event of failure, the caudate nucleus. Patients were followed for 6 months before surgery (M0).

Patients' perspectives on residual symptoms in bipolar disorder: a focus group study.

Euthymic bipolar patients are often impacted by residual symptoms (RSs) that increase the risk of relapse or low functioning. We aimed to identify the perceptions of RSs, barriers to management, and service needs in euthymic bipolar patients. A qualitative methodology (focus group) was used.

Residual symptoms and functional performance in a large sample of euthymic bipolar patients in France (the OPTHYMUM study).

Background: Some residual symptoms were found to be associated with impaired functioning in euthymic bipolar patients, but their impact and relevance are unclear in clinical practice. We re-examined the functional influence of a large set of residual symptoms in 525 euthymic bipolar outpatients using self- and clinician-rated questionnaires (OPTHYMUM study).

Methods: This was a multi-centre, cross-sectional, non-interventional study of adult bipolar outpatients.

Functional analysis of an immune gene of Spodoptera littoralis by RNAi.

Insect immune defences rely on cellular and humoral responses targeting both microbial pathogens and metazoan parasites. Accumulating evidence indicates functional cross-talk between these two branches of insect immunity, but the underlying molecular mechanisms are still largely unknown. We recently described, in the tobacco budworm Heliothis virescens, the presence of amyloid fibers associated with melanogenesis in immune capsules formed by hemocytes, and identified a protein (P102) involved in their assembly.

[Mixed states: evolution of classifications].

The nosological position of mixed states has followed the course of classifying methods in psychiatry, the steps of the invention of the clinic, progress in the organization of care, including the discoveries of psychopharmacology. The clinical observation of a mixture of symptoms emerging from usually opposite clinical conditions is classical. In the 70s, a syndromic specification fixed the main symptom combinations but that incongruous assortment failed to stabilize the nosological concept.

[Endophenotypes of the biorhythms and the sleep in depression].

Chronobiological markers of depression display a biological desynchronization which participates in the pathogenesis of depression. Mood disorders and clock genes have shown significant associations suggesting a possible pathogenetic link between them, providing a privileged base for exploring biorhythmic endophenotypes. They would be useful indicators of vulnerability mechanisms, giving rise to new therapies and prevention programs.

[Treatment initiation in psychotic and manic episodes: French attitudes collected by Focus Group].

An accurate treatment of first episodes in schizophrenia and bipolar disorders has a significant impact on compliance and prognosis. However, existing therapeutic guidelines may be poorly respected and may concern only typical clinical situations. Medical attitudes in clinical practice have been collected and structured on the basis of small interactive meetings (Focus Group [FG]), and a synthesis of practical attitudes has been compared with updated guidelines.

Functional analysis of a fatty acid binding protein produced by Aphidius ervi teratocytes.

Aphidius ervi (Hymenoptera, Braconidae) is an endophagous parasitoid of various aphid species, including Acyrthosiphon pisum (Homoptera, Aphididae), the model host used in the present study. Parasitized hosts show a marked increase of their nutritional suitability for the developing parasitoid larvae. This alteration of the biochemical and metabolic profile is due to a castration process mediated by the combined action of the venom, injected at the oviposition, and of the teratocytes, cells deriving from the dissociation of the embryonic membrane.

The CPP Tat enhances eGFP cell internalization and transepithelial transport by the larval midgut of Bombyx mori (Lepidoptera, Bombycidae).

Cell-Penetrating Peptides (CPPs) are short peptides that are able to translocate across the cell membrane a wide range of cargoes. In the past decade, different mammalian cell lines have been used to clarify the mechanism of CPPs penetration and to characterize the internalization process, which has been described either as an energy-independent direct penetration through the plasma membrane, or as endocytic uptake. Whatever the mechanism involved, the cell penetration properties of these peptides make their use very attractive as vector for promoting the cellular uptake of coupled bioactive macromolecules, such as peptides, proteins and oligonucleotides.

A viral chitinase enhances oral activity of TMOF.

In this study we investigate the combined effect on Heliothis virescens (Lepidoptera, Noctuidae) larvae of Aedes aegypti-Trypsin Modulating Oostatic Factor (Aea-TMOF), a peptide that inhibits trypsin synthesis by the gut, impairing insect digestive function, and Autographa californica nucleopolyhedrovirus Chitinase A (AcMNPV ChiA), an enzyme that is able to alter the permeability of the peritrophic membrane (PM). Aea-TMOF and AcMNPV ChiA were provided to the larvae by administering transgenic tobacco plants, co-expressing both molecules. Experimental larvae feeding on these plants, compared to those alimented on plants expressing only one of the two molecules considered, showed significantly stronger negative effects on growth rate, developmental time and mortality.
