Background: The association between the intestinal microbiota and psychiatric disorders is becoming increasingly apparent. The gut microbiota contributes to colorectal carcinogenesis (CRC), as demonstrated with colibactin-producing Escherichia coli (CoPEC)., Aim: To evaluate the association between CoPEC prevalence and anxiety- and depressive-like behaviors with both preclinical and clinical approaches., Methods: Patients followed after a CRC surgery and for whom the prevalence of CoPEC has been investigated underwent a psychiatric interview. Results were compared according to the CoPEC colonization. In parallel C57BL6/J wild type mice and mice with a CRC susceptibility were chronically infected with a CoPEC strain. Their behavior was assessed using the Elevated Plus Maze test, the Forced Swimming Test and the Behavior recognition system PhenoTyper ® ., Results: In a limited cohort, all patients with CoPEC colonization presented with psychiatric disorders several years before cancer diagnosis, whereas only one patient (17%) without CoPEC did. This result was confirmed in C57BL6/J wild-type mice and in a CRC susceptibility mouse model (adenomatous polyposis coli multiple intestinal neoplasia/+ ). Mice exhibited a significant increase in anxiety- and depressive-like behaviors after chronic infection with a CoPEC strain., Conclusion: This finding provides the first evidence that CoPEC infection can induce microbiota-gut-brain axis disturbances in addition to its procarcinogenic properties., Competing Interests: Conflict-of-interest statement: Pr. Bonnet has nothing to disclose., (©The Author(s) 2024. Published by Baishideng Publishing Group Inc. All rights reserved.)

In photodynamic therapy (PDT), light-sensitive photosensitizers produce reactive oxygen species (ROS) after irradiation in the presence of oxygen. Atomically-precise thiolate-protected gold nanoclusters are molecule-like nanostructures with discrete energy levels presenting long lifetimes, surface biofunctionality, and strong near-infrared excitation ideal for ROS generation in PDT. We directly compare thiolate-gold macromolecular complexes (Au 10 ) and atomically-precise gold nanoclusters (Au 25 ), and investigate the influence of ligands on their photoexcitation. With the ability of atomically-precise nanochemistry, we produce Au 10 SG 10 , Au 10 AcCys 10 , Au 25 SG 18 , and Au 25 AcCys 18 (SG: glutathione; AcCys: N-acetyl-cysteine) fully characterized by high-resolution mass spectrometry. Our theoretical investigation reveals key factors (energetics of excited states and structural influence of surface ligands) and their relative importance in singlet oxygen formation upon one- and two-photon excitation. Finally, we explore ROS generation by gold nanoclusters in living cells with one- and two-photon excitation. Our study presents in-depth analyses of events within gold nanoclusters when photo-excited both in the linear and nonlinear optical regimes, and possible biological consequences in cells., (© 2023.

Background: Skin-restricted lupus is a chronic inflammatory disease associated with high rates of depression and anxiety disorders. Patients without psychiatric disorders can experience anxiety and depressive symptoms at a subclinical level, which could be risk factors for progression towards psychiatric disorders. It was decided, therefore, to investigate the presence of specific symptoms in skin-restricted lupus patients without axis I psychiatric disorders and their impact on the occurrence of axis I psychiatric disorders during the study follow-up., Methods: Longitudinal data of 38 patients and 76 matched controls without active axis I psychiatric disorders from the LuPsy cohort were used. Depressive, neurovegetative, psychic and somatic anxiety symptom scores were established from the Montgomery-Asberg Depression Rating Scale (MADRS) and the Hamilton Anxiety Rating scale (HAMA)., Results: None of the participants had any current active axis I psychiatric disorders but the patients had personality disorders more frequently and had received more past psychotropic treatments than the controls. They also had higher MADRS and HAMA scores than the controls, in particular neurovegetative, psychic anxiety and somatic symptoms scores. No dermatological factor tested was associated with these scores, whereas being a lupus patient was associated with higher neurovegetative and somatic symptoms scores, having a current personality disorder with higher depressive and neurovegetative scores and receiving more past psychotropic treatments with psychic anxiety and somatic symptoms scores. The occurrence of psychiatric disorders during the study follow-up was associated with an elevated psychic anxiety score at baseline and past psychotropic treatment but not with history of psychiatric disorder., Limitations: The LuPsy cohort included a large number of patients with axis I psychiatric disorders, the sample without axis I psychiatric disorders is therefore limited., Conclusions: We observed numerous psychiatric symptoms among the skin-restricted lupus patients. They should therefore receive special attention in the management of their subclinical symptoms before they progress towards full psychiatric disorders., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Rondepierre et al.

Introduction: The aim of this study was to create a new version of the French GTS-QOL adapted to adolescents with GTS aged 12-16 years (GTS-QOL-French-Ado) and to evaluate its psychometric properties., Methods: We assessed the psychometric properties of the GTS-QOL-French-Ado in 84 adolescents (mean age 13.6 years, standard deviation 1.2) in terms of factor structure, internal consistency, reliability and convergent validity with the Child Depression Inventory (CDI), the Multidimensional Anxiety Scale for Children (MASC), the Motor tic, Obsessions and compulsions, Vocal tic Evaluation Survey (MOVES) and the French "Vécu et Santé Perçue de l'Adolescent" (VSP-A), a generic self-administered measure of health-related quality of life (HRQoL) in adolescents., Results: Exploratory factor analysis of the GTS-QOL-French-Ado resulted in a 5-factor solution. The GTS-QOL-French-Ado demonstrated good acceptability with missing values per subscale ranging from 0% to 1.2%, good internal consistency for four of the five subscales with Cronbach's alpha ranging from 0.56 to 0.87 and good test-retest reliability with intraclass correlation coefficients ranging from 0.74 (95% CI: 0.52-0.86) to 0.82 (95% CI: 0.66-0.91). Convergent validity was supported by correlations with CDI, MASC, MOVES, VSP-A and clinical variables., Discussion: The GTS-QOL-French-Ado is the first disease-specific HRQoL tool for French-speaking adolescents with GTS aged 12-16 years, and shows good psychometric properties. Further psychometric testing on responsiveness to change would be of great interest., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2022 Jalenques et al.

The magnitude of the association between psoriasis and depression has been evaluated, but not that between psoriasis and anxiety. The aim of this systematic review and meta-analysis was to examine the prevalence and odds of anxiety disorders and symptoms in patients with psoriasis. Five medical databases (Cochrane Database, EMBASE, PubMed, PsychINFO, ScienceDirect) were searched for relevant literature. A total of 101 eligible articles were identified. Meta-analysis revealed different prevalence rates depending on the type of anxiety disorder: 15% [95% confidence interval [CI] 9-21] for social anxiety disorder, 11% [9-14] for generalized anxiety disorder, and 9% [95% CI 8-10] for unspecified anxiety disorder. There were insufficient studies assessing other anxiety disorders to be able to draw any conclusions on their true prevalence. Meta-analysis also showed a high prevalence of anxiety symptoms (34% [95% CI 32-37]). Case-control studies showed a positive association between psoriasis and unspecified anxiety disorder (odds ratio 1.48 [1.18; 1.85]) and between psoriasis and anxiety symptoms (odds ratio 2.51 [2.02; 3.12]). All meta-analyses revealed an important heterogeneity, which could be explained in each case by methodological factors. The results of this study raise the necessity of screening for the presence of anxiety disorders, as previously recommended for depressive disorders, in patients with psoriasis and, if necessary, to refer such patients for evaluation by a mental health professional and appropriate treatment.

Background: Major depressive disorder with psychotic features (MDDPsy), compared to nonpsychotic MDD, involves an increased risk of suicide and failure to achieve treatment response. Symptom scales can be useful to assess patients with MDDPsy. The aim of the present study was to validate French versions of the Delusion Assessment Scale (DAS) and Psychotic Depression Assessment Scale (PDAS)., Methods: One hundred patients were included. The scales were filled out by psychiatrists. Data from participants who accepted a second interview were used for inter-judge reliability. The scalability and psychometric properties of both scales were assessed., Results: Data from 94 patients were used. Owing to low score variability between patients, the predefined threshold for scalability (≥0.40) was not reached for both scales. Factorial analysis of the DAS identified five factors, different from those of the original version. Five factors were also identified in the PDAS, of which two comprised items from the HDRS and the other three items from the BPRS. Floor and ceiling effects were observed in both scales, due in part to the construction of certain subscales. Unlike the PDAS, the DAS had good internal consistency. Multiple correlations were observed between the DAS dimensions but none between those of the PDAS. Both scales showed good inter-judge reliability. Convergent validity analyses showed correlations with HDRS, BPRS and CGI., Limitations: Inter-judge reliability was calculated from a relatively small number of volunteers., Conclusions: The good psychometric properties of the French versions of the DAS and PDAS could help in assessing MDDPsy, in particular its psychotic features, and hence improve response to treatment and prognosis., Competing Interests: The authors have declared that no competing interests exist.

Introduction: The Gilles de la Tourette Syndrome-Quality of Life Scale (GTS-QOL) is a self-rated disease-specific questionnaire to assess health-related quality of life of subjects with GTS. Our aim was to perform the cross-cultural adaptation of the GTS-QOL into French and to assess its psychometric properties., Methods: The GTS-QOL was cross-culturally adapted by conducting forward and backward translations, following international guidelines. The psychometric properties of the GTS-QOL-French were assessed in 109 participants aged 16 years and above with regard to factor structure, internal consistency, reliability and convergent validity with the MOVES (Motor tic, Obsessions and compulsions, Vocal tic Evaluation Survey) and the WHOQOL-BREF (World Health Organization Quality of Life Brief)., Results: Exploratory factor analysis of the GTS-QOL-French resulted in a 6-factor solution and did not replicate the original structure in four subscales. The results showed good acceptability (missing values per subscale ranging from 0% to 0.9%), good internal consistency (Cronbach's alpha ranging from 0.68 to 0.94) and good test-retest reliability (intraclass correlation coefficients ranging from 0.70 to 0.81). Convergent validity with the MOVES and WHOQOL-BREF scales showed high correlations., Discussion: Our study provides evidence of the good psychometric properties of the GTS-QOL-French. The cross-cultural adaptation and validation of this specific instrument will make it possible to assess health-related quality of life in French-speaking subjects with GTS. The GTS-QOL-French could be recommended for use in future research., Competing Interests: The authors have declared that no competing interests exist.

The association between certain chronic inflammatory skin diseases and psychiatric disorders or conditions has been well documented. However, the exact magnitude of the association between lichen planus and depression/anxiety symptoms and disorders is un-known. A systematic review and pooled meta-analyses were performed to examine the prevalence and odds of depression and anxiety in patients with lichen planus. The meta-analyses showed a high prevalence of signs of depression (27% [19-36%]) and anxiety (28% [21-36%]). The geographical location of the study may partly explain these vari-ations, but method-ological differences could also be involved. Case-control studies showed a strong association between lichen planus and signs of depression (odds ratio 3.79, 95% confidence interval [2.35; 6.12]) or anxiety (odds ratio 2.54, 95% confidence interval [1.73; 3.72]). These results raise the necessity of screening for the presence of depressive and anxiety symptoms or disorders in patients with lichen planus, and of referring such patients for psychiatric evaluation and appropriate treatment, if necessary.

Cognitive memory and introspection disturbances are considered core features of schizophrenia. Moreover, it remains unclear whether or not participants with schizophrenia are more cognitively impaired with ageing than healthy participants. The aims of this study were to use a metacognitive approach to determine whether elderly participants with schizophrenia are able to improve their memory performance using a specific generation strategy and to evaluate the memory benefits for them using this strategy. 20 younger and 20 older participants with schizophrenia and their comparison participants matched for age, gender and education learned paired associates words with either reading or generation, rated judgment of learning (JOL) and performed cued recall. Participants with schizophrenia recalled fewer words than healthy comparison participants, but they benefited more from generation, and this difference was stable with ageing. Their JOL magnitude was lower than that of healthy comparison participants, but JOL accuracy was not affected by either age or the pathology. In spite of their memory deficit, elderly and younger participants with schizophrenia benefited remarkably from the memory generation strategy. This result gives some cause for optimism as to the possibility for participants with schizophrenia to reduce memory impairment if learning conditions lead them to encode deeply., Competing Interests: The authors have declared that no competing interests exist.

Background: The proportion of people living to a very old age is continuously increasing. One of the possibilities explored in policies and services to meet this health and societal challenge is to encourage the very old to continue living at home. This initiative is in line with the wishes of most elderly people. However, owing to the great changes that occur during old age attention should be paid to health-related quality of life (HRQoL). The aims of this study were to assess HRQoL in French community-dwelling people aged 80 years and over and to investigate the sociodemographic and health characteristics and life events associated with HRQoL., Methods: A cross-sectional study was conducted in France to assess the HRQoL of people aged 80 years or more living at home. All people recruited were sent a letter explaining the aim of the study and requesting their consent to take part. Those who accepted then received a series of sociodemographic and medical questionnaires, a questionnaire concerning life events of the previous 12 months and the LEIPAD questionnaire, which assesses HRQoL in elderly people., Results: The data of 184 participants (54.9% female) with a mean age of 83.9 years (almost 40% older than 85 years), were analysed. Low scores, indicating better HRQoL, were obtained on the 'Self-Care' and 'Depression and Anxiety' scales with 50.9 and 40.8% of responders, respectively, having the minimum score of zero. The highest score was found on the 'Sexual Functioning' scale, with 59.1% of participants having the maximum score of 100. Elderly females declared a significantly less satisfactory HRQoL. Deteriorating health, an unsatisfactory environment, not being able to drive, perceived modest income and financial worries negatively affected HRQoL., Conclusion: Identifying factors in our study that are potential determinants of HRQoL would be of direct benefit for individuals. Concrete public policy initiatives concerning means of transport, living environment and financial resources could then be implemented to improve the HRQoL of very old community-dwelling individuals.

Impaired emotional abilities (higher scores of alexithymia and lower levels of emotional awareness) were found in patients with skin-restricted lupus, warranting examination of the relationship between these abilities and the evolution of skin-restricted lupus, using longitudinal data. A total of 75 consecutive outpatients with skin-restricted lupus were recruited and assessed by a dermatologist and a psychiatrist every 6 months over a period of 2.5 years. Alexithymia and emotional awareness were evaluated with the French versions of the Toronto Alexithymia Scale (TAS-20) and the Levels of Emotional Awareness Scale (LEAS). During follow-up, good stability of the LEAS scores was observed, whereas TAS-20 scores varied; those variations were positively associated both with lupus duration and current psychiatric and personality disorders, but not with lupus remission. Such findings regarding 2 complementary aspects of emotional functioning are of direct interest for the management of patients with skin-restricted lupus.

Background: Few studies have addressed health-related quality of life in community-dwelling individuals aged 80 years and above and very few self-assessment quality of life questionnaires have been formally validated in these populations. This study aimed to validate a French version of the LEIPAD, a self-administered questionnaire assessing the health-related quality of life of people aged 80 years and over., Method: A cross-sectional study of people aged 80 years and over living at home in France was conducted. All subjects recruited were sent a letter explaining the study and requesting their consent to take part. Those who accepted then received the questionnaires, including the LEIPAD, which assesses health-related quality of life in the subjects aged 65 years and above. We assessed its psychometric properties: data completeness, score distribution, floor and ceiling effects, internal consistency, item-total correlations, inter-scale correlations, reliability and convergent validity with the Medical Outcome Study Short-Form 36 (SF-36)., Results: The results obtained from 184 older people (mean age of 83.9 years, standard deviation 3.3) showed very good acceptability (missing data between 1.1% and 11.4% for LEIPAD scales) Factor analysis of the instrument confirmed the multi-dimensional structure in seven independent scales similar to the original version. Good internal consistency (Cronbach's alpha ranging from 0.68 to 0.87) and strong test-retest reliability of the LEIPAD scales (intraclass correlation coefficients ranging from 0.77 to 0.95) were found. Convergent validity with the SF-36 showed moderate to strong correlations, consistent with the hypotheses stated., Conclusions: The validation of this specific questionnaire will make it possible to investigate individually the health-related quality of life of French older people living at home and will enable French-speaking investigators to contribute to national and international research projects., Competing Interests: The authors have declared that no competing interests exist.

Psychiatric and personality disorders have been extensively documented in patients with systemic lupus erythematosus (SLE). However, the prevalence of personality disorders in skin-restricted lupus (SRL) patients remains unknown. The aim of this study was to assess the prevalence of personality disorders in SRL outpatients and to examine the associated factors. We evaluated 60 SRL outpatients and 118 controls matched for sex, age and education level. On the basis of the Personality Diagnostic Questionnaire 4+, 38% of patients vs 20% of controls fulfilled the criteria for at least one personality disorder (OR 2.2 [95% CI 1.01-4.6], p = 0.048). Only one patient with a personality disorder had specialised mental health care. Late lupus onset and more frequent past treatments by thalidomide were associated factors. This study evidences a high prevalence of personality disorders in SRL patients and shows that most SRL patients with personality disorder do not receive specialised mental health care.
