- Abstract
Introduction: Polypharmacy in patients with advanced cancer represents a major public health problem, leading to risk of iatrogenesis, decrease of quality of life and increase of healthcare costs. In the field of geriatrics, health policies have been developed to address polypharmacy through the use of deprescribing tools. Recently, palliative care initiatives have been introduced, yet these have not fully considered the specificities of this population, particularly their perceptions. It is therefore important to better understand patients' perceptions of deprescribing in order to adapt tools and actions to make these approaches more effective., Objectives: The aim is to investigate patients' perceptions of deprescribing in palliative oncology care, and to explore factors that may influence patients' attitudes and beliefs about deprescribing and to validate a specific questionnaire (rPATD) in this population. An ancillary study will investigate the relationship between patients' health literacy and their perception of deprescribing., Method: A prospective, observational, multicenter study will be conducted using a sequential mixed exploratory design in a population of patients living with advanced cancer and with a physician-estimated life expectancy of less than 1 year. The study will include an initial qualitative phase. Individual semi-structured interviews using a descriptive approach (thematic analysis) will be conducted (upon saturation). Following analysis of the qualitative data, a quantitative study including 300 patients will be realized to meet secondary objectives. Several data will be collected and 2 self-questionnaires will be administered: the BMQ (beliefs about medicine) and rPATD (perception of deprescribing) possibly supplemented by additional items if required by the qualitative analysis. The auxiliary study will be conducted during this second phase, using a validated self-questionnaire to assess patients' level of literacy., Conclusion: The disparate outcomes will facilitate the understanding of the perception of deprescribing in palliative oncology care, enabling the development of tailored approaches adapted to this population., Trial Registration: ClinicalTrials Identifier: NCT06193083., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Evin et al.

- Abstract
Purpose: To compare the efficacy of treatment of optic neuritis (ON) with corticosteroids (CTC) alone, CTC+plasmapheresis (PLP), and CTC+intravenous immunoglobulin (IVIG)., Design: After an episode of ON, although visual recovery is usually good, some patients may have significant visual sequelae. While the efficacy of first-line CTC is now indisputable, there is no consensus on the nature of second-line treatment. To date, no systematic review has compared the efficacy of treatment of ON with CTC alone, CTC+plasmapheresis (PLP), and CTC+intravenous immunoglobulin (IVIG). A meta-analysis is needed to compare the efficacy of PLP and IVIG in steroid-resistant ON., Methods: This systematic review included all studies comparing at least two of the three treatments for steroid-resistant ON (CTC alone, CTC+PLP, and CTC+IVIG). From all articles published on PubMed between January 2000 and June 2022, two independent ophthalmologists selected studies of interest using the PRISMA method. Methodology, patient characteristics, and outcomes were identified. A network metaanalysis was then performed to compare the efficacy of the three treatments., Results: Six comparative studies were included, representing 209 patients. The percentage of significant visual recovery after CTC alone, CTC+PLP, and CTC+IVIG in the acute treatment of steroid-resistant ON was 30 %, 45 %, and 77 %, respectively. Comparison of CTC+IVIG vs CTC alone, CTC+PLP vs CTC only, and CTC+PLP vs CTC+IVIG yielded odds ratios of 12.81, 2.47, and 0.19 respectively., Conclusion: Treatment of steroid-resistant ON with CTC+PLP or CTC+IVIG is more effective than treatment with CTC alone. Although no study has directly compared the two treatments, IVIG may be more effective than PLP., Competing Interests: Declaration of competing interest None, (Copyright © 2024 Elsevier B.V.

- Abstract
Objectives: To develop a simple, practical methodology to equate or link equivalent domains of the 36-item Short-Form Health Survey (SF-36) and the Patient-Reported Outcomes Measurement Information System 29-item questionnaire (PROMIS-29) using the Rasch framework., Study Design and Setting: In April 2016, the PROMIS-29 and SF-36 were completed by 1501 individuals selected to be representative of the French population. For each domain common to the two questionnaires, a Partial Credit Model was fitted to the items related to that dimension in the two questionnaires. These items were then calibrated on the same metric, which enabled the scores from one questionnaire to be associated with the scores from the other., Results: Six of the seven PROMIS-29 scales and five of the six SF-36 subscales (physical, pain, social, vitality, depression and anxiety domains) were equated or linked. Correspondence tables between scores, with a 95% confidence interval, were established for each domain. A freely available Stata macro program was developed to automatize the equating or linking process., Conclusion: These results should facilitate comparisons across studies using the SF-36 and the PROMIS-29 in France. The equating or linking process developed is simple to implement and can be used in other countries and for other instruments., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Author(s).

- Abstract
Background: The Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) questionnaire evaluates manual therapists' biomedical and biopsychosocial beliefs regarding the management of chronic low back pain. Its usage in clinical settings is an important step in the implementation of national guidelines and policies to improve patient management., Objectives: The objective of this study was to translate the PABS-PT questionnaire into French, to adapt it culturally, and to conduct a psychometric analysis., Design: Qualitative and cross-sectional study., Method: The translation process followed published guidelines with cross-cultural validation by an expert committee. We followed a forward and backward translation procedure and an expert committee, including the original author of the questionnaire and a linguistics expert ensuring good cultural adaptation, issued a finalised version. Psychometric analysis of the French version of the questionnaire was conducted among 390 French manual therapists in two phases. The first phase evaluated structural validity as well as external validity compared with the TSK and BBQ questionnaires. Then, reliability and scalability were analysed. The second phase evaluated test-retest reproducibility by sending the same questionnaire 3 months later., Results: The validity study revealed three subscales: the classic biomedical subscale and two subscales for biopsychosocial beliefs (aetiology of pain and physical activity). With 21 items in total for the PABS-PT-FR, the structural validity scores were good (BM: alpha = 0.82, H = 0.38; Physical Activity: alpha = 0.62, H = 0.32; Aetiology of Pain: alpha = 0.55, H = 0.29)., Conclusions: This study provides a validated tool to assess French physiotherapists' and, more generally, healthcare providers' beliefs about chronic low back pain, with a new insight into the BPS subscale internal construct., (© 2024 John Wiley & Sons Ltd.)

- Abstract
Background and Aims: While the concept of recovery is receiving increasing attention in the context of gambling disorder (GD), no consensus has yet been reached regarding its definition. This scoping review aims to map the literature on GD recovery, identify gaps, and provide insights for a more holistic and patient-centred perspective., Methods: A systematic search of three databases was conducted (PubMed, PsycINFO, and ScienceDirect). Based on the method by which the results of these studies were produced, the studies included were sorted into four categories (quantitative, instrument validation, qualitative, and mixed studies) and subsequently examined using conceptual analysis., Results: One hundred thirteen articles were included in this research after the screening process. In the quantitative and instrument validation studies, recovery was defined or operationalized in terms of abstinence, the absence of a GD diagnosis, or mild GD severity, or by reference to treatment outcomes or controlled gambling. A meta-synthesis of the results of the qualitative studies revealed four core features of recovery (insight, empowerment and commitment, wellbeing enhancement, and reconsideration of the issue of relapse)., Discussion: Discrepancies in definitions, outcomes, and variables used were evident across studies. Additionally, the quantitative and standardized approaches employed in most studies exhibited severe limitations with regard to defining recovery from the subjective and multidimensional perspectives of people recovering from GD., Conclusions: This lack of definitional clarity emphasizes the necessity for further qualitative research. This research should encompass multiple stakeholder perspectives to develop a working definition promoting recovery from a holistic, patient-centred, and tailored approach.

- Abstract
Objective: A large body of literature has examined the links between the use of dopamine replacement therapy (DRT) in Parkinson's disease (PD) and the development of "impulsive-compulsive behaviors (ICBs)." Little is known regarding the link between the development of ICBs and health-related quality of life (HRQOL). We aimed to explore the factors that are associated with poorer HRQOL, especially in relation to DRT-induced ICBs, in a sample of PD patients., Methods: This PARKADD (PARK: PARKinson's disease; ADD: behavioral ADDictions) study was a prospective case‒control study initially designed to assess the factors associated with ICBs in PD patients. A prospective clinical follow-up was added, aiming to capture the long-term evolution of HRQOL in relation to ICBs occurring or worsening after the beginning of PD. We focused on sociodemographic and PD characteristics and the history or presence of ICBs. HRQOL was measured using the Parkinson's Disease Questionnaire-8. A multivariate linear regression was performed to identify factors related to poorer HRQOL., Results: A total of 169 patients were eligible for the follow-up study. The presence of an ICB, a higher levodopa equivalent daily dose (LEDD) and a longer PD duration were significantly associated with poorer HRQOL, with an interaction between LEDD and PD duration., Conclusion: The presence of an ICB was related to poorer HRQOL and should be considered a crucial factor for the management of PD patients. Several studies were recently published that provide guidelines for the management of these patients, with recommendations based on two key principles: prevention and specific treatment.

- Abstract
Aim: This study aimed to evaluate the incidence of self-reported taste and smell alterations (TSA) in cancer paediatric patients and evaluate the impact of TSA on nutritional status in this population. We also developed and validated a composite score to detect TSA in children undergoing chemotherapy., Methods: Paediatric patients who were undergoing chemotherapy in a paediatric oncology unit were included. TSA were assessed from the Gustonco questionnaire from which a composite score was developed and internally validated, eating behaviour was assessed using Child Eating Behaviour Questionnaire, and major weight loss was defined from nutritional status. All data were calculated at 1, 3 and 6 months after chemotherapy start. Associations between nutritional status and scores were studied by using logistic models., Results: Among 49 patients included, TSA occurred in 71.7% of patients at 1 month after chemotherapy start and persisted at 3 and 6 months. TSA led to altered appetite since 1 month after chemotherapy start. The occurrence of a major weight loss at 6 months seemed to be associated with a high Gustonco score., Conclusion: Taste and smell alterations often occurred in paediatric cancer patients after chemotherapy start and seemed to be associated with impaired nutrition at 6 months after chemotherapy., (© 2023 Foundation Acta Paediatrica.

Dubuy Y, Hardouin JB, Blanchin M, and Sébille V
- Abstract
When analyzing patient-reported outcome (PRO) data, sources of differential item functioning (DIF) can be multiple and there may be more than one covariate of interest. Hence, it could be of great interest to disentangle their effects. Yet, in the literature on PRO measures, there are many studies where DIF detection is applied separately and independently for each covariate under examination. With such an approach, the covariates under investigation are not introduced together in the analysis, preventing from simultaneously studying their potential DIF effects on the questionnaire items. One issue, among others, is that it may lead to the detection of false-positive effects when covariates are correlated. To overcome this issue, we developed two new algorithms (namely ROSALI-DIF FORWARD and ROSALI-DIF BACKWARD). Our aim was to obtain an iterative item-by-item DIF detection method based on Rasch family models that enable to adjust group comparisons for DIF in presence of two binary covariates. Both algorithms were evaluated through a simulation study under various conditions aiming to be representative of health research contexts. The performance of the algorithms was assessed using: (i) the rates of false and correct detection of DIF, (ii) the DIF size and form recovery, and (iii) the bias in the latent variable level estimation. We compared the performance of the ROSALI-DIF algorithms to the one of another approach based on likelihood penalization. For both algorithms, the rate of false detection of DIF was close to 5%. The DIF size and form influenced the rates of correct detection of DIF. Rates of correct detection was higher with increasing DIF size. Besides, the algorithm fairly identified homogeneous differences in the item threshold parameters, but had more difficulties identifying non-homogeneous differences. Over all, the ROSALI-DIF algorithms performed better than the penalized likelihood approach. Integrating several covariates during the DIF detection process may allow a better assessment and understanding of DIF. This study provides valuable insights regarding the performance of different approaches that could be undertaken to fulfill this aim., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Dubuy, Hardouin, Blanchin and Sébille.)

- Abstract
Introduction: Malignant tumors of the extremities are uncommon. Their surgical treatment, whether conservative or not, may cause sequelae. Functional assessment of patients is essential for research purposes, but also follow-ups and adaptation of treatments. The Musculoskeletal Tumor Society Rating Scale (MSTS) is a disease-specific functional scoring system often used in English literature. Currently, no studies have been published on a valid French translation of the MSTS, whether for the lower or upper extremities. We, therefore, conducted a prospective study to answer the following questions: (1) Are the proposed adapted French versions of the MSTS valid? (2) Do the psychometric properties of the two versions obtained make their use relevant?, Materials and Methods: The translation and cross-cultural adaptation were carried out following the recommendations of Beaton and Guillemin to obtain two versions: one for patients who had undergone upper extremity surgery (MSTS-UE) and one for those who had undergone lower extremity surgery (MSTS-LE). A prospective multicenter cohort study was then carried out to analyze the psychometric properties of these two versions., Results: A total of 250 patients from 3 referral centers were enrolled in this study. A confirmatory factor analysis (CFA) demonstrated that the two French versions of the MSTS (MSTS-LE and MSTS-UE) were a good fit with a root mean square error of approximation (RMSEA)<0.08 and a comparative fit index (CFI)>0.90. The psychometric properties of the two versions were validated with internal consistency (Cronbach alpha>0.7), convergent validity of each item with its score (> 0.4), and sufficient criterion validity (Pearson correlation coefficient>0.4). The discriminant validity analysis showed that there was a significant correlation between each version and the performance status (PS) (p<0.05)., Conclusion: This study produced a French version of the MSTS scoring system and validated the psychometric properties of the two versions obtained (MSTS-UE and MSTS-LE). Therefore, the French MSTS scoring system is a valid measurement that can be used in international studies., Level of Evidence: I., (Copyright © 2023. Published by Elsevier Masson SAS.)

- Abstract
Background: In emergency medicine, pain is a frequent reason for consultation. However, there is a great variation in its management which is often insufficient. The use intravenous morphine alone or multimodal analgesia with paracetamol is recommended for severe pain. But robust data are lacking to justify the association of paracetamol with morphine versus morphine alone for pain management in the emergency room (ER). The aim of our study is therefore to assess if in patients with acute pain of moderate to severe intensity with a numerical verbal scale (NVS) ≥5 in the ER, the intravenous administration of morphine alone is not inferior to the administration of intravenous morphine combined with paracetamol at 30 min from the first administration of the study drug., Methods: ADAMOPA is a prospective, non-inferiority, multicenter, placebo-controlled, parallel-group, randomized (1:1), double-blind trial. Subjects will be enrolled in the ER if they experience moderate to severe, acute, non-traumatic, and traumatic pain, defined as an NVS ≥5. The primary endpoint will be the between-group difference in mean change in NVS pain scores among patients receiving the combination of intravenous morphine plus paracetamol or intravenous morphine given alone, measured from the time before administration of the study medication to 30 min later., Discussion: This trial will determine the clinical utility of the association of paracetamol with morphine for pain management in the emergency room. The ADAMOPA trial will be conducted in accordance with the International Council on Harmonization Good Clinical Practices., Trial Registration: EudraCT number: 2019-002149-39., Clinicaltrials: gov identifier: NCT04148495.

- Abstract
Background: The Posttraumatic growth inventory (PTGI) aims to assess the positive psychological changes that individuals can perceive after a traumatic life event such as a cancer diagnosis. Several French translations of the PTGI have been proposed, but comprehensive data on their psychometric properties are lacking. This study aimed to provide a more complete assessment of the psychometric properties of one of the most used PTGI translations in early-stage breast cancer and melanoma patients., Methods: A sample of 379 patients completed the PTGI two years after their cancer diagnosis. A confirmatory analysis was first performed to determine whether the initial five-factor structure of the PTGI was adequate for this French version. As issues were identified in the translation and in the questionnaire structure, we performed an exploratory analysis to determine the most suitable structure for this questionnaire. Validity and reliability of the evidenced structured were then assessed., Results: The exploratory analysis evidenced a four-factor structure close to the initial structure: four of the five initial domains were recovered, and items from the unrecovered domain were split into the other domains. This new structure showed good internal consistency and acceptable validity., Conclusions: This study highlights that the process of translation and cross-cultural validation of questionnaires is crucial to obtain valid and reliable psychometric instruments. We advise French psycho-oncology researchers and psychotherapists to (i) use the revised translation of Lelorain et al. (2010) proposed in this manuscript and (ii) use the four scores newly evidenced with a grouping of two response categories., (© 2022. The Author(s).)

- Abstract
Background and Aims: Gambling disorder is characterized by problematic gambling behavior that causes significant problems and distress. This study aimed to develop and validate a predictive model for screening online problem gamblers based on players' account data., Methods: Two random samples of French online gamblers in skill-based (poker, horse race betting and sports betting, n = 8,172) and pure chance games (scratch games and lotteries, n = 5,404) answered an online survey and gambling tracking data were retrospectively collected for the participants. The survey included age and gender, gambling habits, and the Problem Gambling Severity Index (PGSI). We used machine learning algorithms to predict the PGSI categories with gambling tracking data. We internally validated the prediction models in a leave-out sample., Results: When predicting gambling problems binary based on each PGSI threshold (1 for low-risk gambling, 5 for moderate-risk gambling and 8 for problem gambling), the predictive performances were good for the model for skill-based games (AUROCs from 0.72 to 0.82), but moderate for the model for pure chance games (AUROCs from 0.63 to 0.76, with wide confidence intervals) due to the lower frequency of problem gambling in this sample. When predicting the four PGSI categories altogether, performances were good for identifying extreme categories (non-problem and problem gamblers) but poorer for intermediate categories (low-risk and moderate-risk gamblers), whatever the type of game., Conclusions: We developed an algorithm for screening online problem gamblers, excluding online casino gamblers, that could enable the setting of prevention measures for the most vulnerable gamblers.

- Abstract
Background: Meaningfully interpreting patient-reported outcomes (PRO) results from randomized clinical trials requires that the PRO scores obtained in the trial have the same meaning across patients and previous applications of the PRO instrument. Calibration of PRO instruments warrants this property. In the Rasch measurement theory (RMT) framework, calibration is performed by fixing the item parameter estimates when measuring the targeted concept for each individual of the trial. The item parameter estimates used for this purpose are typically obtained from a previous "calibration" study. But imposing this constraint on item parameters, instead of freely estimating them directly in the specific sample of the trial, may hamper the ability to detect a treatment effect. The objective of this simulation study was to explore the potential negative impact of calibration of PRO instruments that were developed using RMT on the comparison of results between treatment groups, using different analysis methods., Methods: PRO results were simulated following a polytomous Rasch model, for a calibration and a trial sample. Scenarios included varying sample sizes, with instrument of varying number of items and modalities, and varying item parameters distributions. Different treatment effect sizes and distributions of the two patient samples were also explored. Cross-sectional comparison of treatment groups was performed using different methods based on a random effect Rasch model. Calibrated and non-calibrated approaches were compared based on type-I error, power, bias, and variance of the estimates for the difference between groups., Results: There was no impact of the calibration approach on type-I error, power, bias, and dispersion of the estimates. Among other findings, mistargeting between the PRO instrument and patients from the trial sample (regarding the level of measured concept) resulted in a lower power and higher position bias than appropriate targeting., Conclusions: Calibration does not compromise the ability to accurately assess a treatment effect using a PRO instrument developed within the RMT paradigm in randomized clinical trials. Thus, given its essential role in producing interpretable results, calibration should always be performed when using a PRO instrument developed using RMT as an endpoint in a randomized clinical trial., (© 2022.

- Abstract
Background and Aims: Parkinson's disease (PD) is one of the most prevalent neurodegenerative diseases. First-line medications consist of drugs that act by counteracting dopamine deficiency in the basal ganglia. Unfortunately, iatrogenic impulsive-compulsive behaviors (ICBs) can occur in up to 20% of PD patients over the course of their illness. ICBs must be considered multifactorial disorders that reflect the interactions of the medication with an individual's vulnerability and the underlying neurobiology of PD. We aimed to explore the predictive genetic, psychopathological and neurological factors involved in the development of ICBs in PD patients by building a complete model of individual vulnerability., Methods: The PARKADD study was a case/non-case study. A total of 225 patients were enrolled ("ICB" group, N = 75; "no ICB" group, N = 150), and 163 agreed to provide saliva samples for genetic analysis. Sociodemographic, neurological and psychiatric characteristics were assessed, and genotyping for the characterization of polymorphisms related to dopaminergic and opioid systems was performed., Results: Factors associated with "ICBs" were younger age of PD onset, personal history of ICB prior to PD onset and higher scores on the urgency and sensation seeking facets of impulsivity. No gene variant was significantly associated, but the association with the opioid receptor mu 1 (OPRM1) rs1799971 polymorphism was close to significance., Discussion and Conclusions: The influence of gene-environment interactions probably exists, and additional studies are needed to decipher the possible role of the opioid system in the development of ICBs in PD patients.

- Abstract
Interpreting observed changes over time in Patient-Reported Outcomes (PRO) measures is still considered a challenge. Indeed, concluding an observed change at group level is statistically significant does not necessarily equate this change is meaningful from the perspective of the patient. To help interpret within and/or between group changes in the measure over time, the estimation of the Minimal Important Difference (MID) of the instrument - the smallest value that patients consider as a perceived change - is useful. In the last 30 years, a plethora of methods and estimators have been proposed to derive this MID value using clinical data from sample of patients. MIDs for hundreds of PROs have been estimated, with frequently a substantial variability in the results depending on the method used. Nonetheless, a rigorous assessment of the statistical performances of numerous proposed methods for estimating MIDs by experimental design such as Monte-Carlo study has never been performed. The purpose of this paper is to thoroughly depict a protocol for a large-scale simulation study designed to investigate the statistical performances, especially bias against a true populational value, of the common proposed estimators for MID. This paper depicts how investigated methods and estimators were retained after the conduct of a systematic review, the design of a conceptual model that formally defines what is the true populational MID value and the translation of the conceptual model into a model allowing the simulation of responses of items to a hypothetical PRO at two times of measurement along with the response to a Patient Global Rating of Change at the second time under the constraint of a known true MID value. A statistical analysis plan is depicted in order to conclude if working hypotheses on what could be appropriate MID estimators will be verified. Strengths, assumptions, and limits of the simulation model are exposed. Finally, we show how this protocol could be the basis for fostering future methodological research on the issue of interpreting changes in PRO measures., (Copyright © 2022.

- Abstract
Personal recovery from psychiatric disorders is a journey toward a satisfying and hopeful life despite the possible persistence of symptoms. This concept has gained interest and become an increasingly important goal in mental health care programmes. Personal Recovery is well described in the context of severe mental illnesses in general, but little is known about this journey in bipolar disorders and the factors underlying it. A systematic review was conducted according to the PRISMA recommendations, focusing on studies exploring personal recovery in bipolar disorder specifically. The latter have integrated a comprehensive approach to the concept, the existing means of measurement or have explored the levers of recovery in care. Twenty-four articles were selected, including seven qualitative, 12 observational, and five interventional studies. The Bipolar Recovery Questionnaire was the only scale developed de novo from qualitative work with bipolar people. Personal recovery did not correlate very closely with symptomatology. Some elements of personal recovery in bipolar disorder were similar to those in other severe mental illnesses: meaning in life, self-determination, hope, and low self-stigma. Specific levers differed: mental relationships with mood swings, including acceptance and decrease in hypervigilance, and openness to others, including trust and closeness. The studies highlighted the role of caregiver posture and the quality of communication within care, as well as the knowledge gained from peers. The choice to exclude articles not focused on bipolar disorder resulted in the provision of very specific information, and the small number of articles to date may limit the scope of the evidence. New components of personal recovery in bipolar disorder emerged from this review; these components could be taken into account in the construction of care tools, as well as in the caregiving posture. Strengthening skills of openness to others could also be a central target of recovery-focused care., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Chirio-Espitalier, Schreck, Duval, Hardouin, Moret and Bronnec.)

- Abstract
Aims: To estimate whether the use of wagering inducements has a significant impact on the gambling behaviors of on-line gamblers and describe this temporal relation under naturalistic conditions., Design: This longitudinal observational study is part of the second stage of the Screening for Excessive Gambling Behaviors on the Internet (EDEIN) research program., Setting: Gambling tracking data from the French national on-line gambling authority (poker, horse race betting and sports betting) and from the French national lottery operator (lotteries and scratch games)., Participants: A total of 9306 gamblers who played poker, horse race or sports betting and 5682 gamblers who played lotteries and scratch games completed an on-line survey. The gender ratio was largely male (between 87.1% and 92.9% for poker, horse race betting and sports betting, and equal to 65.1% for lotteries). Median age ranged from 35 (sports betting) to 53 (horse race betting and lotteries)., Measurements: The survey used the Problem Gambling Severity Index (PGSI) to determine the status of the gamblers (at-risk or not). Gambling tracking data included weekly gambling intensity (wagers, deposits), gambling frequency (number of gambling days), proxies of at-risk gambling behaviors (chasing and breadth of involvement) and use of wagering inducements., Findings: The use of wagering inducements was associated with an increase of gambling intensity [β between -0.06 (-0.08; -0.05) and 0.57 (0.54; 0.60)], gambling frequency [β between 0.12 (0.10; 0.18) and 0.29 (0.28; 0.31)] and at-risk gambling behaviors [odds ratio between 1.32 (1.16; 1.50) and 4.82 (4.61; 5.05)] at the same week of their use. This effect was stronger for at-risk gambling behaviors and at-risk gamblers., Conclusions: Wagering inducements may represent a risk factor for developing or exacerbating gambling problems., (© 2021 The Authors.

- Abstract
Background: The resurgence of heroin use and the misuse of pharmaceutical opioids are some of the reasons for a worldwide increase in opioid dependence. Opioid Medication Therapies (OMT) have amply demonstrated their efficacy. From a medical point of view, the main objectives of OMT concern medical and social outcomes, centred on risk reduction and the cessation of opioid use. But patient points of view can differ and few studies have explored opioid-dependent patient viewpoints on their OMT. This variable seems important to consider in a patient-centred approach. The aim of our study was to explore points of view of people who use drugs (PWUD) treated with OMT, in a large multicentre sample., Method: A cross-sectional multicentre study explored the points of view of PWUD with Opioid Use Disorder following OMT. Data regarding the patients' points of view were collected using a self-administered questionnaire developed by the scientific committee of the study. A descriptive analysis and an exploratory factor analysis were performed to explore the structure of items exploring patient viewpoints., Results: 263 opioid dependent PWUD were included, a majority were men consuming heroin prior to being prescribed OMT. 68% were on methadone, 32% were on buprenorphine. Most PWUD identified a positive impact on their lives, with 92.8% agreeing or strongly agreeing that OMT had changed a lot of things in their lives. The exploratory factor analysis identified three factors: (F1) items related to points of views concerning the objectives and efficacy of OMT; (F2) items related to the legitimacy of OMT as a treatment compared to a drug, (F3) items related to experiences and relationships with OMT., Conclusion: Patient viewpoints on efficacy were correlated with the pharmacological benefits of OMT and with the associated psychosocial measures. The implications of OMT in relationships, such as the feeling of being judged, concerned a majority. Points of view were ambivalent concerning the role of OMT as a treatment or as a drug. Involving patient points of view in therapeutic strategies decisions could help enhance positive views among PWUD on OMT and help PWUD towards their recovery., Trial Registration: OPAL study was registered: (NCT01847729)., (© 2022.

- Abstract
Introduction: COVID-19 sequelae are numerous and multisystemic, and how to evaluate those symptomatic patients is a timely issue. Klok et al proposed the Post-COVID-19 Functional Status (PCFS) Scale as an easy tool to evaluate limitations related to persistent symptoms. Our aim was to analyse PCFS Scale ability to detect functional limitations and its correlation with quality of life in a cohort of patients, 2-9 months after hospitalisation for COVID-19 hypoxemic pneumonia., Methods: PCFS Scale was evaluated in 121 patients together with quality of life and dyspnoea questionnaires, pulmonary function tests and CT scans., Results: We observed a high correlation with multiple questionnaires (Short Form-36, Hospital Anxiety and Depression Scale, modified Medical Research Council, end Borg Six-Minute Walk Test), making the PCFS Scale a quick and global tool to evaluate functional limitations related to various persistent symptoms following COVID-19 pneumonia., Discussion: The PCFS Scale seems to be a suitable instrument to screen for patients who will require careful follow-up after COVID-19 hypoxemic pneumonia even in the absence of pulmonary sequelae., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

- Abstract
Purpose: Kidney transplantation (KT) can impact patients' evaluation of health-related quality of life (HRQoL) as they adapt to their new life with a graft and its changes. Patients may adapt to KT in a different way, depending on whether they were on dialysis prior to transplantation or not (i.e. preemptive group). This may result in lack of measurement invariance between these patients' groups and/or over time (i.e. response shift, RS) which may invalidate the between-group comparison of HRQoL change scores. The aim of this study was to investigate and compare RS before and after KT between these two patients' groups. Measurement invariance was investigated between groups and over time with three measurement occasions., Methods: Adult patients completed the SF-36 at the last visit before KT, and 3, 6 months after. A structural equation model-based procedure was used to (i) detect and take into account measurement non-invariance between groups and RS, if appropriate, (ii) identify the period of occurrence of RS, (iii) study the heterogeneity of RS between the two groups., Results: Before KT (i.e. baseline), measurement invariance was not rejected between dialyzed (n = 196) and preemptive (n = 178) patients' groups. Between baseline and 3 months after KT, similar uniform recalibration was detected on the general health domain in both groups. Uniform recalibration was found between 3- and 6 months after KT on the vitality domain for preemptive patients only., Conclusion: HRQoL, adjusted for RS, increased overall for preemptive and dialyzed kidney transplant patients after transplantation. RS may reflect differing adaptation processes following KT., (© 2021. The Author(s), under exclusive licence to Springer Nature Switzerland AG.)

- Abstract
Background: Transcranial Direct Current Stimulation (tDCS) and Virtual Reality Exposure Therapy (VRET) are individually increasingly used in psychiatric research., Objective/hypothesis: Our study aimed to investigate the feasibility of combining tDCS and wireless 360° full immersive active and embodied VRET to reduce height-induced anxiety., Methods: We carried out a pilot randomized, double-blind, controlled study associating VRET (two 20 min sessions with a 48 h interval, during which, participants had to cross a plank at rising heights in a building in construction) with online tDCS (targeting the ventromedial prefrontal cortex) in 28 participants. The primary outcomes were the sense of presence level and the tolerability. The secondary outcomes were the anxiety level (Subjective Unit of Discomfort) and the salivary cortisol concentration., Results: We confirmed the feasibility of the association between tDCS and fully embodied VRET associated with a good sense of presence without noticeable adverse effects. In both groups, a significant reduction in the fear of height was observed after two sessions, with only a small effect size of add-on tDCS (0.1) according to the SUD. The variations of cortisol concentration differed in the tDCS and sham groups., Conclusion: Our study confirmed the feasibility of the association between wireless online tDCS and active, fully embodied VRET. The optimal tDCS paradigm remains to be determined in this context to increase effect size and then adequately power future clinical studies assessing synergies between both techniques.

- Abstract
Background: Sterols are the main components of fungal membranes. Inhibiting their biosynthesis is the mode of action of azole antifungal drugs that are widely used to treat fungal disease including aspergillosis. Azole resistance has emerged as a matter of concern but little is known about sterols biosynthesis in azole resistant Aspergillus fumigatus ., Methods: We explored the sterol composition of 12 A. fumigatus isolates, including nine azole resistant isolates with TR
34 /L98H, TR46 /Y121F/T289A or TR53 alterations in the cyp51A gene and its promoter conferring azole resistance. Modifications in sterol composition were also investigated after exposure to two azole drugs, itraconazole and voriconazole., Results: Overall, under basal conditions, sterol compositions were qualitatively equivalent, whatever the alterations in the target of azole drugs with ergosterol as the main sterol detected. Azole exposure reduced ergosterol composition and the qualitative composition of sterols was similar in both susceptible and resistant isolates. Interestingly TR53 strains behaved differently than other strains., Conclusions: Elucidating sterol composition in azole-susceptible and resistant isolates is of interest for a better understanding of the mechanism of action of these drugs and the mechanism of resistance of fungi.- Published

- Abstract
Statement of Problem: Intraoral scanners have significantly improved over the last decade. Nevertheless, data comparing intraoral digital scans with conventional impressions are sparse., Purpose: The purpose of this systematic review and meta-analysis was to determine the impact of impression technique (digital scans versus conventional impressions) on the clinical time, patient comfort, and marginal fit of tooth-supported prostheses., Material and Methods: The authors conducted a literature search based on the Population, Intervention, Comparison, and Outcome (PICO) framework in 3 databases to identify clinical trials with no language or date restrictions. The mean clinical time, patient comfort, and marginal fit values of each study were independently extracted by 2 review authors and categorized according to the scanning or impression method. The authors assessed the study-level risk of bias., Results: A total of 16 clinical studies met the inclusion criteria. The mean clinical time was statistically similar for digital scan procedures (784 ±252 seconds) and for conventional impression methods (1125 ±159 seconds) (P>.05). The digital scan techniques were more comfortable for patients than conventional impressions; the mean visual analog scale score was 67.8 ±21.7 for digital scans and 39.6 ±9.3 for conventional impressions (P<.05). The mean marginal fit was 80.9 ±31.9 μm and 92.1 ±35.4 μm for digital scan and conventional impressions, respectively, with no statistically significant difference (P>.05)., Conclusions: Digital scan techniques are comparable with conventional impressions in terms of clinical time and marginal fit but are more comfortable for patients than conventional impression techniques., (Copyright © 2020 Editorial Council for the Journal of Prosthetic Dentistry.

- Abstract
Purpose: Methods for response shift (RS) detection at the individual level could be of great interest when analyzing changes in patient-reported outcome data. Guttman errors (GEs), which measure discrepancies in respondents' answers compared to the average sample responses, might be useful for detecting RS at the individual level between two time points, as RS may induce an increase in the number of discrepancies over time. This study aims to establish the link between recalibration RS and the change in the number of GEs over time (denoted index [Formula: see text]) via simulations and explores the discriminating ability of this index., Methods: We simulated the responses of individuals affected or not affected by recalibration RS (defined as changes in the patients' standard of measurement) to determine whether simulated individuals with recalibration had a greater change in the number of GEs over time than individuals without recalibration. The effects of factors related to the sample, the questionnaire structure and recalibration were investigated. As an illustrative example, the change in the number of GEs was computed in patients suffering from eating disorders., Results: Within simulations, simulated individuals affected by recalibration had, on average, a greater change in the number of GEs over time than did individuals without RS. Some of the parameters related to the questionnaire structure and recalibration magnitude appeared to have substantial effects on the values of [Formula: see text]. Discriminating abilities appeared, however, globally low., Conclusion: Some evidence of the link between recalibration and the change in GEs was found in this study. GEs could be a valuable nonparametric tool for RS detection at a more individual level, but further investigation is needed., (© 2021.

- Abstract
Context: The PP Convergences criteria group together 10 of the most significant clinical criteria for sensitization in the context of chronic pelvic pain. They are the result of a consensus of experts and represent to date the only clinical evaluation guide to identify patients with pelvic perineal pain in whom a pelvic sensitization component can be evoked., Objective: This work concerns the psychometric validation of these criteria. The aim is to answer 3 questions: 1) is the instrument reliable (i.e., sensitive, specific and accurate)?; 2) can we define a screening score for pelvic-perineal pain by sensitization from the CPP criteria?; 3) can combinations of criteria be defined to predict pelvic-perineal sensitization from the CPP criteria?, Methodology and Subjects: In total, 308 patients with pelviperineal pain were recruited during their medical consultation., Procedure: Fifteen expert physicians were asked to judge the presence or absence of the 10 CPP criteria and to make a diagnosis of the presence or absence of pelviperineal sensitization in their patient., Results: ROC curve analysis indicated that a score of 5 was the closest to a perfect score with a sensitivity of 95% and a specificity of 87%. They also indicate that the CPP criteria have a very good sensitivity (97%) and specificity (91%) and present globally a good reproducibility on all the criteria (Kappa>0.6). Finally, the statistical analyses reveal that the most discriminating criterion for predicting sensitization is Q8 (pain persisting after sexual activity)., Conclusion: The CPP criteria represent a very good screening tool for pelvic sensitization. The score of 5 corresponds to the score at which the patient has sufficient clinical criteria to be classified as sensitized., Level of Evidence: 4., (Copyright © 2021.

- Abstract
Background and Aims: Since June 2018, gaming disorder (GD) has been recognized as a disease. It is frequently associated with attention deficit hyperactivity disorder (ADHD), as there are common vulnerability factors and bidirectional interactions between the two disorders. This study aims to evaluate the presence of ADHD symptoms and predictive factors of ADHD among patients with GD., Methods: Ninety-seven patients ≥16 years old referred to the University Hospital of Nantes between 2012 and 2020 for GD were included. The diagnosis of GD was given a posteriori in accordance with the new ICD-11 GD definition. ADHD was screened using the Adult-ADHD Self-Report Scale and the Wender-Utah Rating Scale. A multivariate logistic regression model was used to identify explanatory factors for ADHD-GD comorbidity., Results: The rate of GD patients who screened positive for ADHD was 39%. Predictive factors of ADHD-GD comorbidity were impulsivity (higher score on the negative urgency dimension) and low self-esteem., Discussion: The rate of ADHD found among patients with GD is consistent with that from the literature on internet GD but higher than that found for other behavioural addictions. The identification of a higher negative urgency score and low self-esteem as predictive factors of AHDH-GD comorbidity indicates that gaming could be considered a dysfunctional way to cope with emotional dysregulation in ADHD or to virtually escape., Conclusions: Comorbid ADHD must be taken into consideration to minimize its functional impact on GD patients and gaming-related damage. In contrast, the evaluation of gaming habits in patients with ADHD could be useful for both prevention and care.

- Abstract
Background: Dementia with Lewy bodies remains underdiagnosed in clinical practice mainly because of the low sensitivity of existing diagnostic criteria and a strong overlap with Alzheimer's pathology that can mask the Lewy phenotype., Objective: The objective of this study was therefore to develop and validate a new clinical scale designed to detect signs of Lewy body disease, called LeSCoD for Lewy body Screening scale in Cognitive Disorders., Methods: 128 patients who fulfilled the clinical criteria of dementia with Lewy bodies (DLB; n = 32), Alzheimer's disease (AD; n = 77) or both (n = 19) was prospectively enrolled.
18 F-DOPA PET imaging and/or CSF biomarkers were available in some patients. LeSCoD scale was systematically administered and the potential correlation with18 F-DOPA PET imaging was evaluated in a subgroup of patients., Results: LeSCoD scale showed robust internal and external validity. We determined a cut-off of 10 above which the sensitivity and specificity for Lewy body disease diagnosis were 86% and 95%, respectively. The LeSCoD scale correlated with striatal dopamine uptake in18 F-DOPA PET., Conclusion: LeSCoD scale is a simple and reliable tool for the evaluation of Lewy body disease in routine clinical practice, with a higher sensitivity and specificity than the existing criteria. It might be an alternative to the use of dopamine-specific imaging., (© 2021. Springer-Verlag GmbH Germany, part of Springer Nature.)- Published
