AimThe anticholinergic properties of medications are associated with poorer cognitive performance in schizophrenia. Numerous scales have been developed to assess anticholinergic burden and yet, there is no consensus indicating which anticholinergic burden scale is more relevant for patients with schizophrenia. We aimed to identify valid scales for estimating the risk of iatrogenic cognitive impairment in schizophrenia.MethodsWe identified 27 scales in a literature review. The responses to neuropsychological tests of 839 individuals with schizophrenia or schizoaffective disorder in the FACE-SZ database were collected between 2010 and 2021. We estimated the association between objective global cognitive performance and the 27 scales, the number of psychotropic drugs, and chlorpromazine and lorazepam equivalents in bivariable regressions in a cross-sectional design. We then adjusted the bivariable models with covariates: the predictors significantly associated with cognitive performance in multiple linear regressions were considered to have good concurrent validity to assess cognitive performance.ResultsEight scales, the number of psychotropic drugs, and drug equivalents were significantly associated with cognitive impairment. The number of psychotropic drugs, the most convenient predictor to compute, was associated with worse executive function (Standardized β = −0.12, p = .004) and reasoning (Standardized β = −0.08, p = .037).ConclusionAnticholinergic burden, the number of psychotropic drugs, and drug equivalents were weakly associated with cognition, thus suggesting that cognitive impairment in schizophrenia and schizoaffective disorder is explained by factors other than medication. The number of psychotropic drugs was the most parsimonious method to assess the risk of iatrogenic cognitive impairment.

Background: Metabolic syndrome (MetS) is a highly prevalent and harmful medical disorder often comorbid with psychosis where it can contribute to cardiovascular complications. As immune dysfunction is a key shared component of both MetS and schizophrenia (SZ), this study investigated the relationship between immune alterations and MetS in patients with SZ, whilst controlling the impact of confounding clinical characteristics including psychiatric symptoms and comorbidities, history of childhood maltreatment and psychotropic treatments. Method: A total of 310 patients meeting DSM-IV criteria for SZ or schizoaffective disorders (SZA), with or without MetS, were systematically assessed and included in the FondaMental Advanced Centers of Expertise for Schizophrenia (FACE-SZ) cohort. Detailed clinical characteristics of patients, including psychotic symptomatology, psychiatric comorbidities and history of childhood maltreatment were recorded and the serum levels of 18 cytokines were measured. A penalized regression method was performed to analyze associations between inflammation and MetS, whilst controlling for confounding factors. Results: Of the total sample, 25% of patients had MetS. Eight cytokines were above the lower limit of detection (LLOD) in more than 90% of the samples and retained in downstream analysis. Using a conservative Variable Inclusion Probability (VIP) of 75%, we found that elevated levels of interleukin (IL)-6, IL-7, IL-12/23 p40 and IL-16 and lower levels of tumor necrosis factor (TNF)-α were associated with MetS. As for clinical variables, age, sex, body mass index (BMI), diagnosis of SZ (not SZA), age at the first episode of psychosis (FEP), alcohol abuse, current tobacco smoking, and treatment with antidepressants and anxiolytics were all associated with MetS. Conclusion: We have identified five cytokines associated with MetS in SZ suggesting that patients with psychotic disorders and MetS are characterized by a specific “immuno-metabolic” profile. This may help to design tailored treatments for this subgroup of patients with both psychotic disorders and MetS, taking one more step towards precision medicine in psychiatry.

ABSTRACT: We studied the chemical composition and the in vivo AMEn content and apparent (AID) and standardized (SID) ileal digestibility of CP and amino acids (AA) of 27 samples of soybean meals (SBM) from Argentina (ARG), Brazil (BRA), and USA, collected in Spain. On 88% DM basis, the BRA meals had more CP (46.9 vs. 46.0 and 45.9%; P < 0.05) and less sucrose (5.21 vs. 6.28 and 6.47%; P < 0.001) and stachyose (4.20 vs. 4.66 and 4.78%; P < 0.05) than the USA and ARG meals. Urease activity, protein dispersibility index, KOH protein solubility, and trypsin inhibitor activity values, were higher for the USA meals than for the South American meals (P < 0.05). In the in vivo trial, broilers received a common crumble diet from 0 to 16 d of age and then, their respective experimental diets (53% of a N-free diet and 47% of each of the 27 SBM tested) in mash form, for 5 d. The AMEn (2,334 vs. 2,282 and 2,277 kcal/kg; P = 0.062) and the AID (87.3 vs. 86.7 and 86.4%; P = 0.054) and SID (91.9 vs. 91.2 and 90.8%; P < 0.05) of the protein, were greater for the USA meals than for the ARG and BRA meals. In fact, the SID of Lys (93.5 vs. 93.0 and 92.1%; P < 0.001) and of the sum of Lys, Met, Thr, Trp, and Cys (91.4 vs. 91.0 and 90.2%; P < 0.05) were greater for the USA meals than for the ARG and BRA meals. In summary, the chemical composition, protein quality indicators, AMEn content, and ileal digestibility of the CP and the AA of the SBM, varied with the country of origin of the soybeans. In order to increase the accuracy of the feed formulation process, the composition and nutrient content of commercial batches of SBM, by country of origin should be controlled and periodically updated.

ABSTRACT: The influence of the Ca and nutrient content of the diet fed from 16 to 19 wk of age, on egg production, egg quality, and tibiae mineralization, was studied in brown egg-laying hens from 16 to 63 wk of age. The experimental design was completely randomized with 4 prelay diets organized as a 2 × 2 factorial with 2 levels of Ca (2.5 vs. 3.8%) and 2 standardized ileal digestible Lys (g/kg) to AMEn (Mcal/kg) ratios (DLys:ME; 2.84 vs. 3.13) as main effects. From 20 to 63 wk of age, all hens received a common diet with 2.75 Mcal AMEn/kg, 0.75% DLys, and 3.8% Ca. Each treatment was replicated 18 times and the experimental unit was a cage with 10 hens. Hen production and egg quality traits were measured by period (4 wk), feeding phase (prelay and lay), and cumulatively (16–63 wk of age) and tibiae mineralization was measured at 63 wk of age. During the prelay phase, an increase in Ca delayed egg production (P = 0.065), reduced feed intake (P < 0.05), and increased BW gain (P < 0.01) and percentage of shell of the egg (P < 0.05). An increase in the DLys:ME ratio increased feed intake (P < 0.01) and reduced egg size (P < 0.01). Nutrient content of the prelay diets did not affect hen production during the lay phase, except egg weight that increased (P < 0.05) in hens previously fed the low DLys:ME ratio. Eggshell quality (weight, percentage, strength, and thickness) in this phase was better (P < 0.05) in hens previously fed 3.8% Ca. Cumulatively (16–63 wk of age), hens fed the high Ca prelay diets had better shell quality but tibiae mineralization was not affected. In conclusion, an increase in Ca content of the prelay diet from 2.5 to 3.8% improved shell quality for the entire egg cycle without showing any negative effect on hen production.

The influence of the energy and the standardized ileal digestible lysine (DLys) content of the diet on egg production and egg quality, was studied in brown-egg laying hens from 18 to 41 wk of age. The experimental design was completely randomized with 10 treatments organized as a 2 × 5 factorial with 2 energy concentrations (2,750 and 2,800 kcal AMEn/kg) and 5 levels of DLys (values varied from 0.66 to 0.78% and 0.67 to 0.79%, for the low and high energy diets, respectively). Each treatment was replicated 10 times (10 hens per replicate). The data were analyzed using the MIXED procedure of SAS with energy concentration and DLys content of the diets as main effects. In addition, the effects of the DLys on the variables studied were partitioned into its lineal and quadratic components. From 18 to 21 wk of age (pre-peak phase), diet composition had limited effects on egg production. From 22 to 41 wk of age (peak phase), however, an increase of 50 kcal AMEn/kg diet increased egg weight (P < 0.05) and tended to improve energy intake (P = 0.083) and feed conversion ratio (P = 0.074). An increase in DLys improved linearly (P < 0.001) egg production, egg weight, egg mass, feed conversion, and energy conversion ratio, and tended to increase BW gain (P = 0.074). Diet composition did not any affect egg quality trait except shell strength that increased linearly (P < 0.05) with increases in the DLys. Cumulatively (18–41 wk of age), egg weight increased (P < 0.05) as the energy and the DLys content of the diet increased. In summary, an increase in energy and DLys content of the diet had limited effects on egg production during the prepeak phase but improved egg production, feed conversion ratio, and BW gain during the peak phase. The data indicate that hens require at least 839 mg DLys/d to maximize egg production in the peak production phase.

We studied the effects of restricting the access to feed on the anticipatory eating behavior, growth performance, and the development of the proximal part of the gastrointestinal tract (GIT) in broilers. The experiment consisted in physical restriction of the access of broilers to feed for 0, 4, 6, or 8 h per day from 7 to 19 D of age. At 10, 13, 16, and 19 D of age, immediately before the start of the feed restriction (FR) period, 2 birds per cage were euthanized to evaluate crop and gizzard development. The experimental design was completely randomized, and the linear (L) and quadratic (Q) effects of fasting length on growth performance and GIT traits were determined. In addition, the effect of broiler age on GIT development was studied. From 7 to 19 D of age, ADFI (L, Q; P ≤ 0.05) and BW gain (L; P ≤ 0.01) decreased as the length of the FR period increased, with most of the differences observed with 6 or more hours of fasting. However, feed conversion ratio was not affected by FR length. The relative weight of the crop (% BW) and its fresh content increased (L; P ≤ 0.001) and the moisture of the digesta (%) decreased (L; P ≤ 0.001) as the FR period increased. The DM content (g) of the crop increased with FR, with most of the differences observed with 6 or more hours of fasting (L, Q; P ≤ 0.001). At 19 D of age, the Lactobacillus spp. count in the crop increased (L; P ≤ 0.05) with increase in the FR period. Fasting did not affect any gizzard trait at any age. In summary, physical restriction of the access to feed for 6 h or more reduced BW gain but did not affect feed conversion ratio in broilers from 7 to 19 D of age. Feed restriction for 4 to 8 h stimulated the anticipatory feeding behavior and crop development in broilers.

The relevance of the study is due to the need to study the characteristics of the resettlement of the local Evenki group of the Olekma River Basin, which influenced the modern land use and economic and cultural relations of Evenki living now in the Olekminsky District of the Republic of Sakha (Yakutia), the Kalarsky and Tungiro-Olekminsky Districts of the Trans-Baikal Territory and the Tyndinsky District of Amur region. The article focuses on the study of the Evenki population dynamics based on a comparative analysis of the materials of the censuses of the 20th century. For comparison, current data on the number of Evenks in their areas of residence according to the 2010 census are given. An analysis of archival sources showed that changes in the resettlement of Evenk clans occurred simultaneously with changes in the administrative-territorial division. Factographic materials found in the National Archives of the Republic of Sakha (Yakutia) confirm that when deciding on the administrative-territorial structure, the opinions and proposals of the local population were taken into account. Author’s maps were compiled, which allowed a spatial analysis of the distribution of the population and the forms of organization of the Evenki economy. It was found out that each region has its own specific land use determined by administrative decisions and regional policies.

ABSTRACT: The influence of nutrient density and standardized ileal digestible lys (DLys) content of the diet on egg production and egg quality traits, was studied in brown-egg laying hens from 19 to 59 wk of age. The experimental design was completely randomized with eight treatments arranged as a 2×4 factorial with two AMEn concentrations (2,680 and 2,780 kcal/kg) and four levels of DLys (0.68, 0.72, 0.76, and 0.80%). Each treatment was replicated nine times and the experimental unit was a cage with nine hens. Hen production, egg components (proportion of albumen, yolk, and shell), egg quality traits (Haugh units, egg shell strength, and incidence of broken, dirty, and shell-less eggs) were measured by period (28 d) and cumulatively. Data were analyzed as a completely randomized design with energy concentration, level of DLys, and their interactions as main effects. In addition, the effects of the level of DLys on the variables studied, were partitioned into its linear and quadratic components. No interactions between AMEn and DLys content of the diet were detected for any of the traits studied and therefore, only main effects are presented. An increase in the AMEn concentration of the diet from 2,680 to 2,780 kcal/kg increased energy intake (P < 0.05) and egg weight (P < 0.001) and improved feed conversion ratio (P < 0.05). An Increase in DLys from 0.68 to 0.80% did not affect the number of eggs produced but increased linearly egg weight (P < 0.01) and egg mass production (P < 0.05). Diet did not affect egg quality. In conclusion, an increase in the AMEn content of the diet from 2,680 to 2,780 kcal/kg increased egg weight and improved feed efficiency. Laying hens require no more than 744 mg DLys/d (corresponding to 0.68% DLys) to optimize egg production. However, when the objective is to maximize egg weight, hens should consume at least 843 mg DLys/d (corresponding to 0.76% D Lys).

Introduction: Previous studies set out cognitive impairments in major depression. However, only two studies were performed among patients suffering from treatment-resistant depression (TRD) and conducted on limited sample sizes. Here, we aimed to characterize cognitive impairments in TRD, and their association with the severity of depression and daily functioning. Method: We included 288 patients suffering from TRD (178 women, 52.5 ± 13.1 years old). They undertook sociodemographic, clinical, daily functioning and neuropsychological testing (TMT, Baddeley task, verbal fluencies, WAIS-4 subtests, D2 and RLRI-16). We compared our patients’ performances to theoretical performances of the general population. Results: TRD was associated with poorer neuropsychological performances, except for similarities task. We found an effect of depression severity on processing speed and memory, and an impact on daily functioning affecting memory, selective attention and executive function. Conclusion: Patients suffering from TRD have significant cognitive impairments. Therapeutic interventions should be developed to manage such impairments.

Background: The objective of this study was to develop a conceptual framework to define a domain map describing the experience of patients with severe mental illnesses (SMIs) on the quality of mental health care. Methods: This study used an exploratory qualitative approach to examine the subjective experience of adult patients (18–65 years old) with SMIs, including schizophrenia (SZ), bipolar disorder (BD) and major depressive disorder (MDD). Participants were selected using a purposeful sampling method. Semistructured interviews were conducted with 37 psychiatric inpatients and outpatients recruited from the largest public hospital in southeastern France. Transcripts were subjected to an inductive analysis by using two complementary approaches (thematic analysis and computerized text analysis) to identify themes and subthemes. Results: Our analysis generated a conceptual model composed of 7 main themes, ranked from most important to least important as follows: interpersonal relationships, care environment, drug therapy, access and care coordination, respect and dignity, information and psychological care. The interpersonal relationships theme was divided into 3 subthemes: patient-staff relationships, relations with other patients and involvement of family and friends. All themes were spontaneously raised by respondents. Conclusion: This work provides a conceptual framework that will inform the subsequent development of a patient-reported experience measure to monitor and improve the performance of the mental health care system in France. The findings showed that patients with SMIs place an emphasis on the interpersonal component, which is one of the important predictors of therapeutic alliance. Trial registration: NCT02491866

Introduction: Genetic polymorphisms in genes encoding enzymes metabolizing psychotropics drugs result in various isoenzymes with different catalytic efficacies. Of particular interest, some of these isoenzymes are highly catalytic leading to an ultrarapid metabolism (UM) of their substrate medication, which in turn results in lower medication concentrations and possibly poor clinical outcomes, including a higher risk for suicidal behavior. In this study, we investigate the role of CYP2D6 (metabolizing most antidepressant medications) and CYP2C19 (important in metabolizing antipsychotics) UM isoenzymes on suicidal behavior among a cohort of patients with schizophrenia., Methods: One hundred and seventy-eight patients diagnosed with schizophrenia were recruited from the day hospital of a regional psychiatric academic hospital. Lifetime suicide attempts were compared between groups of patients stratified according to their enzymatic profile. Several socio-demographics and clinical covariates were controlled for., Results: Among the 178 patients, 16 and 44 were UM as determined by their CYP2D6 and CYP2C19 genotype respectively. Univariate analysis showed a significant association between suicidal attempts and CYP2D6 and CYP2C19 UM status (P=0.041 and P=0.029 respectively). These associations remained significant in multivariate analyses (adjusted for age, sex, dose exposure and antidepressant use…) for both CYP2D6 (P=0.020, OR=4.096, 95% CI [1.25-13.48]) and CYP2C19 (P=0.016, OR=2.680, 95% CI [1.21-5.95])., Conclusion: This study suggests that the UM phenotypes for both CYP2D6 and CYP2C19 are associated with an increased risk for suicide attempts in patients with schizophrenia., (Copyright © 2024 L'Encéphale, Paris.

Background: Osteoarthritis and rheumatoid arthritis (RA) are prevalent chronic joint disorders, with prevalence rates varying by sex. However, few studies have comprehensively documented the factors contributing to the sex-specific prevalence of osteoarthritis and RA, including sociological factors and the impact of the COVID-19 pandemic., Objective: This study aims to identify long-term trends in the sex-specific prevalence of osteoarthritis and RA from 2005 to 2021 while examining the factors that serve as vulnerabilities specific to each sex within the context of the COVID-19 pandemic., Methods: Data were collected from a nationally representative sample of 110,225 individuals through the Korea National Health and Nutrition Examination Survey from 2005 to 2021. The study included patients aged 19 years and older diagnosed with osteoarthritis or RA in South Korea. Data were analyzed using weighted trends to accurately represent the sample population, with a 95% CI. Weighted logistic and regression models were used to identify vulnerable groups at risk of osteoarthritis or RA during the pandemic to assess sex-specific trends., Results: In total, 110,225 individuals (n=48,410, 43.92% male participants) were analyzed from 2005 to 2021, with prevalence rates remaining stable over time and higher in female than in male participants. Notably, during the pandemic, female participants aged 60 years and older exhibited a prevalence of osteoarthritis that was 4.92 times greater than male participants and a prevalence of RA that was 6.44 times greater (osteoarthritis: prevalence ratio [PR] 69.78, 95% CI 41.66-116.88; RA: PR 17.27, 95% CI 8.75-34.07). In terms of osteoarthritis, male participants did not show a significant association with BMI (PR 1.40, 95% CI 1.21-1.61; P=.47), whereas female participants exhibited a significantly higher vulnerability within the obese group (PR 1.68, 95% CI 1.55-1.83; P<.001). Regarding RA, lower education levels were associated with increased vulnerability, with male participants showing a greater risk than female participants (male participants: PR 2.29, 95% CI 1.61-3.27 and female participants: PR 1.50, 95% CI 1.23-1.84)., Conclusions: This study reveals that women in South Korea have a higher prevalence of osteoarthritis and RA than men. Understanding these sex-specific trends and identifying vulnerability factors can enhance preventive efforts and patient care., (©Seoyoung Park, Yejun Son, Hyeri Lee, Hayeon Lee, Jinseok Lee, Jiseung Kang, Lee Smith, Masoud Rahmati, Elena Dragioti, Mark A Tully, Guillaume Fond, Laurent Boyer, Jun Hyuk Lee, Damiano Pizzol, Jaeyu Park, Selin Woo, Dong Keon Yon.

Vision impairment (VI) and eye diseases such as age-related macular degeneration (AMD), diabetic retinopathy (DR), glaucoma and cataract have been reported to be associated with cognitive impairment and dementia, however, to date, very little attempt has been made to collate and synthesizes such literature. Therefore, the aim of this umbrella review is to systematically assesses the credibility and certainty of evidence of associations between vision impairment (VI) and eye diseases with cognitive impairment, dementia and dementia subtypes. We conducted an umbrella review of meta-analyses by screening articles in any language in PubMed, MEDLINE (Ovid), EMBASE, Web of Science, Cochrane CENTRAL and CDSR published from database inception up to May 30, 2024. Quality appraisal of each included original meta-analysis was assessed using A Measurement Tool for Assessing Systematic Reviews 2 (AMSTAR2). The certainty of the evidence was based on statistical significance, study size, heterogeneity, small study effects, prediction intervals (PI), and bias. We followed an a-priori protocol registered with PROSPERO (CRD42024564249). We identified 13 meta-analyses (AMSTAR 2; high accuracy of the findings 1, moderate 10, and low 2) that included 232 original articles based on 99,337,354 participants. Overall, no evidence was highly suggestive or convincing. Suggestive evidence was found for associations between cataract and dementia (equivalent odds ratio [eOR] 1.20, 95 %CI, 1.16-1.25), cataract and Alzheimer's disease (eOR 1.21, 95 %CI, 1.15-1.28), and AMD and Alzheimer's disease (eOR 1.27, 95 %CI, 1.27-1.27). Weak evidence was found for associations between VI and dementia (eOR 1.50, 95 %CI, 1.23-1.84), DR and dementia (eOR 1.33, 95 %CI, 1.17-1.50), cataract and vascular dementia (eOR 1.26, 95 %CI, 1.09-1.45), VI identified by cross-sectional studies and cognitive impairment (eOR 2.37, 95 %CI, 2.31-2.44), and VI identified by objective measures and cognitive impairment (eOR 1.56, 95 %CI, 1.12-2.18). The observed suggestive level of evidence for the relationship between eye disease and dementia (as well as dementia subtypes) suggests that policy and interventions to aid in the prevention and management of eye disease may also aid in the prevention of dementia syndrome. Where the level of evidence is weak, further studies are needed with stronger methodological approaches., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: Despite the widespread use of attention-deficit hyperactivity disorder (ADHD) medications and their known sympathomimetic effects on the cardiovascular system, cardiovascular risk assessment of these medications using comprehensive global data is limited. This study investigated the association between individual ADHD medications and cardiovascular disease (CVD) using global pharmacovigilance data., Methods: Reports from the World Health Organization international pharmacovigilance database were utilized (1967-2023; total reports, n=131,255,418). Reporting odds ratios (ROR), and information components (IC) were calculated to evaluate the association between each medication and specific CVDs., Results: We identified 13,344 CVD cases related to ADHD medications out of 146,489 cases of all reports on ADHD medications. Cumulative reports on ADHD medications have shown a steady increase, notably in adults since 2010. ADHD medications were associated with a higher risk of CVD overall (ROR [95 % CI], 1.60 [1.58-1.63]; IC [IC 0.25 ], 0.63 [0.60]), with a higher association observed in females than in males. Among specific CVDs, all drugs were associated with an increased risk of torsade de pointes/QT prolongation, cardiomyopathy, and myocardial infarction. Conversely, heart failure, stroke, and cardiac death/shock were exclusively associated with amphetamines. Lisdexamfetamine showed a weaker association with all CVDs compared to amphetamines, and methylphenidate exhibited the lowest overall association with CVD. Atomoxetine had the second-highest association with torsade de pointes/QT prolongation., Conclusions: The associations between CVDs and ADHD medications vary, with amphetamines posing a higher risk, while lisdexamfetamine and methylphenidate exhibit better safety profiles., Competing Interests: Declaration of Competing Interest All the authors declared no competing interests., (Copyright © 2024 Elsevier B.V.

Aim: To evaluate the potential association between suicidality and glucagon-like peptide-1 receptor agonists (GLP-1RAs), as well as other medications used for obesity and diabetes, using comprehensive global data., Materials and Methods: This study utilized the World Health Organization's pharmacovigilance database, encompassing adverse drug reaction reports from 1967 to 2023, from 170 countries (total reports, N = 131 255 418). We present the reported odds ratios (RORs) with 95% confidence intervals (CIs) and information component (IC) with IC 025 regarding the association between GLP-1RA use and suicidality., Results: Although reports of GLP-1RA-associated suicidality increased gradually from 2005 to 2023 (n = 332), no evidence of an association was observed (ROR 0.15 [95% CI 0.13 to 0.16]; IC -2.77 [IC 025 -2.95]). The lack of evidence of an association persisted regardless of whether GLP-1RAs were used for diabetes treatment (ROR 0.13 [95% CI 0.11 to 0.14]; IC -2.95 [IC 025 -3.14]) or obesity treatment (ROR 0.44 [95% CI 0.34 to 0.58]; IC -1.16 [IC 025 -1.62]). However, an association was found between suicidality and other diabetes medications excluding GLP-1RAs (ROR 1.13 [95% CI 1.10 to 1.15]; IC 0.17 [IC 025 0.13]). Similarly, the potential association with suicidality was observed in medications used to treat obesity excluding GLP-1RAs (ROR 1.08 [95% CI 1.01 to 1.14]; IC 0.10 [IC 025 0.01])., Conclusions: The suspected association between GLP-1RA use and suicidality, as raised by the European Medicines Agency, was not found in our global analysis. This indicates that the sporadic reports of GLP-1RA-associated suicidality are likely influenced by factors such as comorbidities present in the GLP-1RA user population., (© 2024 John Wiley & Sons Ltd.)

Background: Amidst reports that one in five doctors and one in four nurses might leave their professions within three to five years due to high levels of burnout, this qualitative review explored the deeper crisis impacting healthcare workers in France, questioning whether factors beyond burnout contributed to their distress., Methodology: This study analyzed testimonies from French healthcare workers and reviewed relevant literature to uncover the underlying causes of their distress., Results: The qualitative analysis revealed profound distress among healthcare workers, stemming from a misalignment between their ethical standards, specifically the principle to 'put patients first,' and the practical realities of their work. Testimonies underscored unsustainable working conditions and economic pressures that compel healthcare workers to make decisions that compromise care quality and their own integrity. Nurses reported closing their practices due to non-profitability, forced to prioritize financial considerations over patient needs. Similarly, general practitioners expressed disillusionment, feeling disconnected from the type of medicine they aspired to practice. This distress goes beyond mere burnout, touching on deep-seated conflicts between personal values and professional demands, leading to significant attrition among healthcare workers. Comparative insights from the United States highlight a global trend where healthcare professionals face diminishing trust in systems that favor financial or operational efficiency over patient-centric care. 'Moral Injury,' as identified in our literature review, aptly describes the situation faced by French healthcare workers. It refers to the psychological distress that occurs when they cannot practice according to their ethical beliefs due to external constraints-whether from profit maximization in predominantly financialized systems like those in the United States or from funding and management gaps in public systems like those in France., Conclusion: Healthcare workers observe that the French healthcare system, once praised for its excellence and accessibility, no longer allows them to put patients at the heart of their concerns, in contradiction with their values. It is therefore essential to recognize the existence of "Moral Injury" to guide the structural and organizational reforms necessary to transform our healthcare system., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

There is no comprehensive umbrella review exploring the connection between schizophrenia and various health outcomes. Therefore, we aimed to systematically review existing meta-analyses about schizophrenia-associated comorbid health outcomes and validate the evidence levels. We performed an umbrella review of meta-analyses of observational studies to explore comorbid health outcomes in individuals with schizophrenia. Searches were conducted across PubMed/MEDLINE, EMBASE, ClinicalKey, and Google Scholar up to September 5, 2023, targeting meta-analyses of observational studies related to comorbid health outcomes in individuals with schizophrenia. We applied AMSTAR2 for data extraction and quality assessment, adhering to PRISMA guidelines. Evidence credibility was evaluated and categorized by evidence quality. Our protocol was registered with PROSPERO (CRD42024498833). Risk and protective factors were analyzed and presented through equivalent odds ratios (eRR). In this umbrella review, we analyzed 9 meta-analyses, including 88 original articles, covering 21 comorbid health outcomes with over 66 million participants across 19 countries. Patients with schizophrenia showed significant associations with multiple health outcomes, including asthma (eRR, 1.71 [95% CI, 1.05-2.78], class and quality of evidence [CE] = non-significant), chronic obstructive pulmonary disease (1.73 [1.25-2.37], CE = weak), pneumonia (2.63 [1.11-6.23], CE = weak), breast cancer of female patients (1.31 [1.04-1.65], CE = weak), cardiovascular disease (1.53 [1.12-2.11], CE = weak), stroke (1.71 [1.30-2.25], CE = weak), congestive heart failure (1.81 [1.21-2.69], CE = weak), sexual dysfunction (2.30 [1.75-3.04], CE = weak), fracture (1.63 [1.10-2.40], CE = weak), dementia (2.29 [1.19-4.39], CE = weak), and psoriasis (1.83 [1.18-2.83] CE = weak). Our study underscores the imperative for an integrated treatment approach to schizophrenia, highlighting its broad impact across respiratory, cardiovascular, sexual, neurological, and dermatological health domains. Given the predominantly non-significant to weak evidence levels, further studies are needed to reinforce our understanding., (© 2024.

Background: Despite several studies on self-evaluation of health and body shape, existing research on the risk factors of self-perceived overweight is insufficient, especially during the COVID-19 pandemic., Objective: This study aims to identify the risk factors affecting self-perceived overweight and examine how the prevalence of self-perceived overweight has changed before and during the COVID-19 pandemic. Specifically, we analyzed the impact of altered lifestyles due to COVID-19 on this phenomenon., Methods: The data used in the study were obtained from middle and high school students who participated in the Korean Youth Risk Behavior Web-based Survey (N=1,189,586). This survey was a 2-stage stratified cluster sampling survey representative of South Korean adolescents. We grouped the survey results by year and estimated the slope in the prevalence of self-perceived overweight before and during the pandemic using weighted linear regression, as well as the prevalence tendencies of self-perceived overweight according to various risk factors. We used prevalence ratios to identify the risk factors for self-perceived overweight. In addition, we conducted comparisons of risk factors in different periods to identify their associations with the COVID-19 pandemic., Results: The prevalence of self-perceived overweight was much higher than BMI-based overweight among 1,189,586 middle and high school participants (grade 7-12) from 2005 to 2022 (female participants: n=577,102, 48.51%). From 2005 to 2019 (prepandemic), the prevalence of self-perceived overweight increased (β=2.80, 95% CI 2.70-2.90), but from 2020 to 2022 (pandemic) it decreased (β=-0.53, 95% CI -0.74 to -0.33). During the pandemic, individuals with higher levels of stress or lower household economic status exhibited a more substantial decrease in the rate of self-perceived overweight. The prevalence of self-perceived overweight tended to be higher among individuals with poor academic performance, lower economic status, poorer subjective health, and a higher stress level., Conclusions: Our nationwide study, conducted over 18 years, indicated that self-perceived overweight decreased during the COVID-19 period while identifying low academic performance and economic status as risk factors. These findings suggest the need for policies and facilities to address serious dieting and body dissatisfaction resulting from self-perceived overweight by developing counseling programs for adolescents with risk factors such as lower school performance and economic status., (©Jinyoung Jeong, Seungjun Lee, Kyeongmin Lee, Seokjun Kim, Jaeyu Park, Yejun Son, Hyeri Lee, Hayeon Lee, Jiseung Kang, Masoud Rahmati, Damiano Pizzol, Lee Smith, Guillermo F López Sánchez, Elena Dragioti, Guillaume Fond, Laurent Boyer, Selin Woo, Sang Youl Rhee, Dong Keon Yon.

Background: Adolescents frequently encounter a spectrum of psychiatric conditions, predominantly depressive and anxiety disorders, along with various behavioral disturbances., Objective: This investigation aims to delineate the prevalence of depressive disorders among adolescents in urban Vietnam and to elucidate the interrelationships between familial and school-related dynamics and adolescent depression., Materials and Methods: A cross-sectional survey was conducted in 2022, involving 507 students aged 15 to 17 from high schools in Hanoi, Vietnam. Reynolds Adolescent Depression Scale - Second Edition (RADS-2) was used to assess the presence of depressive symptoms. Social-demographic characteristics, adolescent-family and adolescent-school relationships, and academic environment characteristics of high school students were interviewed. Multivariate Tobit regression models were employed to discern contributory factors across four domains of RADS-2., Results: Among the 507 adolescents, the mean scores on the RADS scale were 15.1 ± 4.2 for the dysphoric mood domain, 16.4 ± 4.0 for the anhedonia-negative domain, 13.1 ± 4.4 for the negative self-evaluation domain, and 12.4 ± 3.7 for the somatic complaints domain. The analysis indicated that adolescents with suboptimal parental relationships, absence of confidants, frequent parental conflicts, exposure to parental arguments, substantial exam-related stress, or overwhelming academic demands were more likely to exhibit elevated depressive symptoms. Conversely, adolescents who were satisfied with their friendships at school and received care, support from teachers or friends, and involved in school's extracurricular activities lower exhibited levels of depression., Conclusions: Findings reveal the significant impact of family and peer relationships, as well as academic stress, on the development of depressive symptoms. These significant results inform the design and development of future interventions aimed at mitigating depression risks among high school students, emphasizing the crucial roles of both educational institutions and family dynamics., Competing Interests: Declaration of competing interest 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 © 2024 Elsevier Masson SAS.

Background: The coronavirus disease 2019 (COVID-19) pandemic, a global health crisis, profoundly impacted all aspects of daily life. Adolescence, a pivotal stage of psychological and social development, is heavily influenced by the psychosocial and socio-cultural context. Hence, it is imperative to thoroughly understand the psychosocial changes adolescents experienced during the pandemic and implement effective management initiatives., Data Sources: We examined the incidence rates of depressive and anxiety disorders among adolescents aged 10-19 years globally and regionally. We utilized data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 to compare pre-pandemic (2018-2019) and pandemic (2020-2021) periods. Our investigation covered 204 countries and territories across the six World Health Organization regions. We conducted a comprehensive literature search using databases including PubMed/MEDLINE, Scopus, and Google Scholar, employing search terms such as "psychosocial", "adolescent", "youth", "risk factors", "COVID-19 pandemic", "prevention", and "intervention"., Results: During the pandemic, the mental health outcomes of adolescents deteriorated, particularly in terms of depressive and anxiety disorders. According to GBD 2021, the incidence rate of anxiety disorders increased from 720.26 [95% uncertainty intervals (UI) = 548.90-929.19] before the COVID-19 pandemic (2018-2019) to 880.87 per 100,000 people (95% UI = 670.43-1132.58) during the COVID-19 pandemic (2020-2021). Similarly, the incidence rate of major depressive disorder increased from 2333.91 (95% UI = 1626.92-3138.55) before the COVID-19 pandemic to 3030.49 per 100,000 people (95% UI = 2096.73-4077.73) during the COVID-19 pandemic. This worsening was notably pronounced in high-income countries (HICs). Rapid environmental changes, including heightened social anxiety, school closures, economic crises, and exacerbated racism, have been shown to adversely affect the mental well-being of adolescents., Conclusions: The abrupt shift to remote learning and the absence of in-person social interactions heightened feelings of loneliness, anxiety, sadness, and stress among adolescents. This change magnified existing socioeconomic disparities, posing additional challenges. These complexities profoundly impact adolescents' well-being, especially vulnerable groups like those from HICs, females, and minorities. Acknowledging the underreporting bias in low- to middle-income countries highlights the importance of addressing these mental health alterations in assessments and interventions within these regions as well. Urgent interventions are crucial as the pandemic-induced mental stress may have lasting effects on adolescents' mental health., (© 2024. Children's Hospital, Zhejiang University School of Medicine.)

We aimed to assess the association between antibiotic exposure in fetal and postnatal life (within six months after birth) and the risk of neuropsychiatric disorders in childhood. A nationwide, population-based birth cohort study(infants, n = 3,163,206; paired mothers, n = 2,322,735) was conducted in South Korea, with a mean follow-up duration of 6.8 years, using estimates of hazard ratio [HR] and 95 % confidence intervals (CIs). Following propensity score matching including the baseline variables, antibiotic exposure in both fetal (HR,1.07 [95 % CI, 1.05-1.08]) and postnatal life (1.05 [1.03-1.07]) was associated with an increased risk of overall childhood neuropsychiatric disorders. A synergistic effect was observed with prenatal and postnatal exposures (1.12 [1.09-1.15]). The risk increases with the increasing number and duration of prescriptions. Significant associations were found for both common (1.06 [1.05-1.08]) and severe outcomes (1.17 [1.09-1.26]), especially for intellectual disability (1.12 [1.07-1.17]), ADHD (1.10 [1.07-1.13]), anxiety (1.06 [1.02-1.11]), mood (1.06 [1.00-1.12]), and autism (1.03 [1.01-1.07]). When comparing siblings with different exposure statuses to consider familial factors, prenatal and postnatal exposure risk increased to 10 % (95 % CI, 6-12) and 12 % (7-17), respectively. Similar results were observed in the unmatched and health screening cohort, which considers maternal obesity, smoking, and breastfeeding. Based on these findings, clinicians may consider potential long-term risks when assessing the risk-benefit of early-life antibiotic prescription., Competing Interests: Declaration of competing interest None reported., (Copyright © 2024 Elsevier B.V.

Improving vaccine coverage among children is crucial to prevent the long-term consequences of COVID-19 infections and the emergence of resistant COVID-19 variants, especially in resource-scarce settings. This study determined factors influencing the willingness to take and pay for COVID-19 vaccine for children among Vietnamese healthcare professionals and the public. A Theory-Based discrete-choice experiment was focused on a different topic related to vaccines, including the COVID-19 vaccine for children, Monkeypox, the adult COVID-19 booster, the HIV vaccine, and a potential future pandemic. The recruitment period was from April to August 2022, and a total of 5700 Vietnamese individuals aged 16 and above from various regions of the country participated in the study. The data for the sub-study on the COVID-19 vaccination for children was completed by 891 of these participants. Most participants agreed on vaccination for all children. Among healthcare professionals it was 76.2% and 69.3% for the general population. Healthcare professionals were the main source of vaccine information (70.7%). Payment options of 50%, 100%, and full subsidy were the most popular. Concerns about vaccine characteristics were associated with lower acceptance among healthcare professionals and the general public. The burden of historical medical expenses negatively correlated with willingness to pay for vaccination, while service satisfaction positively correlated with willingness to pay. To develop an effective vaccination program among children in Vietnam, providing accurate information and satisfying vaccine services, primarily through knowledgeable and professional healthcare providers, can improve the willingness to vaccinate and pay for the COVID-19 vaccine., (© 2024.

Background: Although previous studies have investigated trends in unmet health care and dental care needs, most have focused on specific groups, such as patients with chronic conditions and older adults, and have been limited by smaller data sets., Objective: This study aims to investigate the trends and relative risk factors for unmet health care and dental care needs, as well as the impact of the COVID-19 pandemic on these needs., Methods: We assessed unmet health care and dental care needs from 2009 to 2022 using data from the Korea Community Health Survey (KCHS). Our analysis included responses from 2,750,212 individuals. Unmet health care or dental care needs were defined as instances of not receiving medical or dental services deemed necessary by experts or desired by patients., Results: From 2009 to 2022, the study included 2,700,705 individuals (1,229,671 men, 45.53%; 673,780, 24.95%, aged 19-39 years). Unmet health care needs decreased before the COVID-19 pandemic; however, during the pandemic, there was a noticeable increase (β diff 0.10, 95% CI 0.09-0.11). Unmet dental care needs declined before the pandemic and continued to decrease during the pandemic (β diff 0.23, 95% CI 0.22-0.24). Overall, the prevalence of unmet dental care needs was significantly higher than that for unmet health care needs. While the prevalence of unmet health care needs generally decreased over time, the β difference during the pandemic increased compared with prepandemic values., Conclusions: Our study is the first to analyze national unmet health care and dental care needs in South Korea using nationally representative, long-term, and large-scale data from the KCHS. We found that while unmet health care needs decreased during COVID-19, the decline was slower compared with previous periods. This suggests a need for more targeted interventions to prevent unmet health care and dental care needs., (©Yeji Kim, Soeun Kim, Somin Lee, Jaeyu Park, Ai Koyanagi, Lee Smith, Min Seo Kim, Guillaume Fond, Laurent Boyer, Guillermo Felipe López Sánchez, Elena Dragioti, Hyeon Jin Kim, Hayeon Lee, Yejun Son, Minji Kim, Sunyoung Kim, Dong Keon Yon.

Background: We aimed to systematically review meta-analyses on the link between attention-deficit/hyperactivity disorder (ADHD) and a broad range of psychiatric, physical, and behavioral health conditions (PROSPERO; no.CRD42023448907)., Results: We identified 22 meta-analyses that included 544 primary studies, covering 76 unique conditions in over 234 million participants across 36 countries and six continents. We found high-certainty evidence for the associations between ADHD and neuropsychiatric conditions (bipolar disorders, personality disorders, schizophrenia, and pragmatic language skills), night awakenings, obesity, decayed incipient surfaces, asthma, astigmatism, hyperopia and hypermetropia, strabismus, and suicide ideation. Moderate-certainty evidence suggested that ADHD was associated with headache, mood/affective disorders, depression, bruxism, bone fractures, atopic rhinitis, vision problems, suicide attempts, completed suicide, and all-cause mortality. Low-certainty evidence indicated associations with eating disorders, sleep efficiency, type 2 diabetes, dental trauma prevalence, atopic diseases, and atopic dermatitis. Very low-certainty evidence showed associations between ADHD and several sleep parameters., Conclusion: We found varied levels of evidence for the associations of ADHD with multiple health conditions. Therefore, clinicians should consider a wide range of neurological, psychiatric, sleep and suicide-related, metabolic, musculoskeletal, oral, allergic, and visual conditions, as well as the increased risk of mortality when assessing individuals with ADHD., Competing Interests: Declaration of Competing Interest We declare no competing interests., (Copyright © 2024 Elsevier B.V.

Aim: This study classified 99 countries into four income groups and then analysed the impact of secondhand smoke (SHS) exposure at home, in public places and at school, on current cigarette smoking prevalence., Methods: We utilised data from the WHO Global Youth Tobacco Survey and a meta-analysis was conducted to evaluate the prevalence and weighted odds ratios (wORs) of adolescent smoking behaviour and SHS exposure locations., Results: Both smoking behaviours increased with higher national income levels. Smoking behaviours in high and upper-middle-income countries (HICs and UMICs) exhibited an association with SHS exposure in public places (HIC: wOR, 3.50 [95% CI, 2.85-4.31]; UMIC: wOR, 2.90 [2.60-3.23]) compared to home. Low- and lower-middle-income countries (LICs and LMICs) showed an association with SHS exposure in the home (LIC: wOR, 5.33 [3.59-7.93]; LMIC: wOR, 2.71 [2.33-3.17]) than public places. The association between current cigarette smoking and SHS exposure at home increased with lower income levels, while anticipated future use of any form of tobacco with SHS exposure in public places rose in lower income countries., Conclusions: Targeted interventions based on income levels are essential, emphasising home strategies in lower income countries and public place efforts in higher income countries., (© 2024 Foundation Acta Paediatrica.

Background: Suicide is the second leading cause of death in young people worldwide and is responsible for about 52,000 deaths annually in children and adolescents aged 5-19 years. Familial, social, psychological, and behavioral factors play important roles in suicide risk. As traumatic events such as the COVID-19 pandemic may contribute to suicidal behaviors in young people, there is a need to understand the current status of suicide in adolescents, including its epidemiology, associated factors, the influence of the pandemic, and management initiatives., Data Sources: We investigated global and regional suicide mortality rates among children and adolescents aged 5-19 years using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. The suicide mortality rates from 1990 to 2019 were examined in 204 countries and territories across six World Health Organization (WHO) regions. Additionally, we utilized electronic databases, including PubMed/MEDLINE and Scopus, and employed various combinations of terms such as "suicide", "adolescents", "youth", "children", "risk factors", "COVID-19 pandemic", "prevention", and "intervention" to provide a narrative review on suicide within the pediatric population in the post-pandemic era., Results: Despite the decreasing trend in the global suicide mortality rate from 1990 to 2019, it remains high. The mortality rates from suicide by firearms or any other specified means were both greater in males. Additionally, Southeast Asia had the highest suicide rate among the six WHO regions. The COVID-19 pandemic seems to contribute to suicide risk in young people; thus, there is still a strong need to revisit appropriate management for suicidal children and adolescents during the pandemic., Conclusions: The current narrative review integrates up-to-date knowledge on suicide epidemiology and the effects of the COVID-19 pandemic, risk factors, and intervention strategies. Although numerous studies have characterized trends in suicide among young people during the pre-pandemic era, further studies are required to investigate suicide during the pandemic and new strategies for suicide prevention in the post-pandemic era. It is necessary to identify effective prevention strategies targeting young people, particularly those at high risk, and successful treatment for individuals already manifesting suicidal behaviors. Care for suicidal children and adolescents should be improved with parental, school, community, and clinical involvement., (© 2024. Children's Hospital, Zhejiang University School of Medicine.)

Background: Although several meta-analyses have examined the association between bipolar disorder (BD) and its comorbid health outcomes, this evidence has not been comprehensively assembled., Objective: We aimed to systematically review existing meta-analyses based on multiple physical outcomes and validate the evidence level by examining the existing certainty of evidence., Methods: We systematically searched databases, including PubMed/MEDLINE, Embase, Google Scholar, and CINAHL, for articles published up to July 2023. We included meta-analyses of cohort, case-control, and/or cross-sectional studies investigating any comorbid health outcomes in patients with BD. We conducted quality assessments of the included meta-analysis using AMSTAR2. The credibility of findings was categorized into five levels of class and quality of evidence (CE), including convincing, highly suggestive, suggestive, weak, or not significant., Results: We analyzed 12 meta-analyses, including 145 original articles, covering 14 unique health outcomes with over 60 million participants across 29 countries and five continents. Among 14 health outcomes, BD was significantly associated with eight comorbid health outcomes, including dementia (equivalent odds ratio [eOR], 2.96 [95 % confidence intervals {CI}, 1.69-5.17]; CE=suggestive), Parkinson's disease (3.35 [1.72-6.53]; CE=suggestive), asthma (1.86 [1.42-2.42]; CE=weak), toxoplasmosis (1.69 [1.21-2.37]; CE=weak), hypertension (1.28 [1.02-1.60]; CE=convincing), breast cancer (1.33 [1.15-1.55]; CE=weak), obesity (1.64 [1.30-1.99]; CE=suggestive), and type 2 diabetes mellitus (1.98 [1.55-2.52]; CE=weak)., Conclusion: Individuals with BD are predisposed to numerous comorbid physical conditions, though these links are supported by various evidence levels and necessitate further studies. It is imperative that physicians be aware of these potential comorbidities in patients with BD and take proactive measures to manage them., Competing Interests: Declaration of Competing Interest None., (Copyright © 2024 Elsevier B.V.

Purpose: To evaluate diabetic retinopathy (DR) screening global adherence rate and the association between sociodemographic and clinical variables and adherence rates to DR screening in individuals with diabetes., Design: Systematic review and meta-analysis., Methods: This systematic review was registered with International Prospective Register of Systematic Reviews (ID: CRD42024507035). We conducted a systematic review of relevant literature from inception of databases to February 24, 2024, using electronic databases searches including PubMed, MEDLINE (Ovid), EMBASE, Web of Science, Cochrane CENTRAL, and CDSR and national level DR screening databases through Google searches following PRISMA guidelines. The articles were screened for title and abstract and then for the full-text reports by two independent reviewers and study quality was appraised. Meta-analysis was performed using random effects model to calculate the pooled effects size and 95% confidence interval (CI) of each finding., Results: Data from a total of 11,383,715 participants from 77 studies and two national websites from 28 countries over five continents were included. Global DR screening adherence rate was 66.9% in high-income countries and 39.3% in low-and-middle-income countries. DR screening adherence rate was lowest in Africa (36.1%) and was highest in Europe (81.3%). Older age (odds ratio [OR] 1.45, 95% CI 1.30-1.62), higher education level (OR = 1.65, 95% CI 1.45-1.78), marriage (OR = 1.42, 95% CI 1.14-1.77), living in an urban area (OR = 1.57, 95% CI 1.08-2.29), higher family income (OR = 1.29, 95% CI 1.24-1.35), having any health insurance (OR = 1.90, 95% CI 1.56-2.31), longer duration of diabetes (OR = 1.57, 95% CI 1.27-1.94), type 2 diabetes (OR = 1.68, 95% CI 1.34-2.10), family history of diabetes (OR = 2.25, 95% CI 1.56-3.25), vision impairment (OR = 2.07, 95% CI 1.43-2.98), history of eye diseases (OR = 1.99, 95% CI 1.36-2.90), insulin treatment (OR = 1.38, 95% CI 1.37-1.39), and good mental health (OR = 1.14, 95% CI 1.04-1.24) were associated with DR screening adherence., Conclusion: This meta-analysis provides key information about which population subgroups may require more targeted intervention and highlights the urgent need to identify ways to improve adherence to DR screening., Registration Information: PROSPERO; ref. no.

Introduction: Mindfulness meditation has gained prominence in somatic and psychiatric care in several countries including France. Studies have shown its effectiveness in various conditions, in particular the prevention of depressive relapses. However, there are criticisms and concerns about its potential links to Buddhism and spirituality, raising issues of secularism and sectarianism. This issue is particularly conflicting in France with regard its historical and political relationship with secularism., Objectives: This study aims to assess quantitative data regarding the impact of mindfulness meditation on spirituality and religiosity using quantitative validated scales., Methods: A systematic review was conducted. PubMed was searched for relevant studies using keywords related to mindfulness and spirituality/religiosity scales. Four scales assessing spirituality were identified: FACIT-sp, INSPIRIT, DSES, and DUREL. Qualitative analysis determined if scale items pertained to spirituality or other topics considered by opponents to mindfulness as "at risk" for deviances or sectarian aberrations. Quantitative analysis assessed the effect size of changes in scale scores before and after mindfulness meditation interventions., Results: Eighteen studies were analyzed, with varying scales and program durations including 1272 participants. Qualitative analysis showed that most scales contained items related to spirituality as well as "at risk" elements like religion and mysticism. Quantitative analysis revealed that a few studies reported significant increases in spirituality scores following mindfulness meditation, but the clinical relevance of these changes was questioned. In general, control groups had smaller score changes., Interpretation: While some studies suggest a potential increase in spirituality due to mindfulness meditation, the clinical significance of these findings remains uncertain. Moreover, mindfulness meditation's ties to Buddhism are disputed, and its roots are intertwined with various psychotherapy traditions that incorporate spirituality. The role of secularism in psychotherapy is also debated in France, emphasizing the need for proper use and regulation policy rather than prohibition of mindfulness-based approaches. This study highlights the complexity of assessing the impact of mindfulness meditation on spirituality and religiosity. It suggests that a pragmatic approach focusing on risk and harm reduction may be more suitable than labeling the practice as "at risk". Further research is needed to clarify these issues in the specific cultural context of France., (Copyright © 2024 L'Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.)

We investigated whether SARS-CoV-2 infection is associated with short- and long-term neuropsychiatric sequelae. We used population-based cohorts from the Korean nationwide cohort (discovery; n = 10,027,506) and the Japanese claims-based cohort (validation; n = 12,218,680) to estimate the short-term (<30 days) and long-term (≥30 days) risks of neuropsychiatric outcomes after SARS-CoV-2 infection compared with general population groups or external comparators (people with another respiratory infection). Using exposure-driven propensity score matching, we found that both the short- and long-term risks of developing neuropsychiatric sequelae were elevated in the discovery cohort compared with the general population and those with another respiratory infection. A range of conditions including Guillain-Barré syndrome, cognitive deficit, insomnia, anxiety disorder, encephalitis, ischaemic stroke and mood disorder exhibited a pronounced increase in long-term risk. Factors such as mild severity of COVID-19, increased vaccination against COVID-19 and heterologous vaccination were associated with reduced long-term risk of adverse neuropsychiatric outcomes. The time attenuation effect was the strongest during the first six months after SARS-CoV-2 infection, and this risk remained statistically significant for up to one year in Korea but beyond one year in Japan. The associations observed were replicated in the validation cohort. Our findings contribute to the growing evidence base on long COVID by considering ethnic diversity., (© 2024.

Background: Given the increasing focus on patient safety in healthcare systems worldwide, understanding the impact of Continuous Quality Improvement Programs (QIPs) is crucial. QIPs, including Morbidity and Mortality Conferences (MMCs) and Experience Feedback Committees (EFCs), have been identified as effective strategies for enhancing patient safety culture. These programs engage healthcare professionals in the identification and analysis of adverse events to foster a culture of safety (ie the product of individual and group value, attitudes, and perceptions about quality and safety). This study aimed to determine whether patient safety culture differed regarding care provider participation in MMCs and EFCs activities., Methods: A cross-sectional web-only survey was conducted in 2022 using the Hospital Survey on Patient Safety Culture (HSOPS) among 4780 employees at an 1836-bed, university-affiliated hospital in France. We quantified the mean differences in the 12 HSOPS dimension scores according to MMCs and EFCs participation, using Cohen d effect size. We performed a multivariate analysis of variance to examine differences in dimension scores after adjusting for background characteristics., Results: Of 4780 eligible employees, 1457 (30.5%) participated in the study. Among the respondents, 571 (39.2%) participated in MMCs or EFCs activities. Participants engaged in MMCs or EFCs reported significantly higher scores in six out of twelve HSOPS dimensions, particularly in "Nonpunitive response to error", "Feedback and communication about error", and "Organizational learning" (Overall effect size = 0.14, 95% confidence interval = 0.11 to 0.17, P<0.001). Notably, involvement in both MMCs and EFCs was associated with higher improvements in patient safety culture compared to non-participation or singular involvement in either program. However, certain dimensions such as "Staffing", "Hospital management support", and "Hospital handoffs and transition" showed no significant association with MMCs or EFCs participation, highlighting broader systemic challenges., Conclusion: The study confirms the positive association between participation in MMCs or EFCs and an enhanced culture of patient safety, emphasizing the importance of such programs in fostering an environment conducive to learning, communication, and nonpunitive responses to errors. While MMCs or EFCs are effective in promoting certain aspects of patient safety culture, addressing broader systemic challenges remains crucial for comprehensive improvements in patient safety., Competing Interests: Laurent Boyer reports honoraria/has been a consultant for Lundbeck, outside the submitted work.

Sub-optimal response in schizophrenia is frequent, warranting augmentation strategies over treatment-as-usual (TAU). We assessed nutraceuticals/phytoceutical augmentation strategies via network meta-analysis. Randomized controlled trials in schizophrenia/schizoaffective disorder were identified via the following databases: PubMed, MEDLINE, EMBASE, Scopus, PsycINFO, CENTRAL, and ClinicalTrials.gov. Change (Standardized Mean Difference = SMD) in total symptomatology and acceptability (Risk Ratio = RR) were co-primary outcomes. Secondary outcomes were positive, negative, cognitive, and depressive symptom changes, general psychopathology, tolerability, and response rates. We conducted subset analyses by disease phase and sensitivity analyses by risk of bias and assessed global/local inconsistency, publication bias, risk of bias, and confidence in the evidence. The systematic review included 49 records documenting 50 studies (n = 2384) documenting 22 interventions. Citicoline (SMD =-1.05,95%CI = -1.85; -0.24), L-lysine (SMD = -1.04,95%CI = -1.84; -0.25), N-acetylcysteine (SMD = -0.87, 95%CI = -1.27; -0.47) and sarcosine (SMD = -0.5,95%CI = -0.87-0.13) outperformed placebo for total symptomatology. High heterogeneity (tau 2  = 0.10, I 2  = 55.9%) and global inconsistency (Q = 40.79, df = 18, p = 0.002) emerged without publication bias (Egger's test, p = 0.42). Sarcosine improved negative symptoms (SMD = -0.65, 95%CI = -1.10; -0.19). N-acetylcysteine improved negative symptoms (SMD = -0.90, 95%CI = -1.42; -0.39)/general psychopathology (SMD = -0.76, 95%CI = -1.39; -0.13). No compound improved total symptomatology within acute phase studies (k = 7, n = 422). Sarcosine (SMD = -1.26,95%CI = -1.91; -0.60), citicoline (SMD = -1.05,95%CI = -1.65;-0.44), and N-acetylcysteine (SMD = -0.55,95%CI = -0.92,-0.19) outperformed placebo augmentation in clinically stable participants. Sensitivity analyses removing high-risk-of-bias studies confirmed overall findings in all phases and clinically stable samples. In contrast, the acute phase analysis restricted to low risk-of-bias studies showed a superior effect vs. placebo for N-acetylcysteine (SMD = -1.10, 95%CI = -1.75,-0.45), L-lysine (SMD = -1.05,95%CI = -1.55, -0.19), omega-3 fatty acids (SMD = -0.83,95%CI = -1.31, -0.34) and withania somnifera (SMD = -0.71,95%CI = -1.21,-0.22). Citicoline (SMD = -1.05,95%CI = -1.86,-0.23), L-lysine (SMD = -1.04,95%CI = -1.84,-0.24), N-acetylcysteine (SMD = -0.89,95%CI = -1.35,-0.43) and sarcosine (SMD = -0.61,95%CI = -1.02,-0.21) outperformed placebo augmentation of TAU ("any phase"). Drop-out due to any cause or adverse events did not differ between nutraceutical/phytoceutical vs. placebo+TAU. Sarcosine, citicoline, and N-acetylcysteine are promising augmentation interventions in stable patients with schizophrenia, yet the quality of evidence is low to very low. Further high-quality trials in acute phases/specific outcomes/difficult-to-treat schizophrenia are warranted., (© 2024. The Author(s), under exclusive licence to Springer Nature Limited.)

Background: A previous study reported significant excess mortality among non-COVID-19 patients due to disrupted surgical care caused by resource prioritization for COVID-19 cases in France. The primary objective was to investigate if a similar impact occurred for medical conditions and determine the effect of hospital saturation on non-COVID-19 hospital mortality during the first year of the pandemic in France., Methods: We conducted a nationwide population-based cohort study including all adult patients hospitalized for non-COVID-19 acute medical conditions in France between March 1, 2020 and 31 May, 2020 (1st wave) and September 1, 2020 and December 31, 2020 (2nd wave). Hospital saturation was categorized into four levels based on weekly bed occupancy for COVID-19: no saturation (< 5%), low saturation (> 5% and ≤ 15%), moderate saturation (> 15% and ≤ 30%), and high saturation (> 30%). Multivariate generalized linear model analyzed the association between hospital saturation and mortality with adjustment for age, sex, COVID-19 wave, Charlson Comorbidity Index, case-mix, source of hospital admission, ICU admission, category of hospital and region of residence., Results: A total of 2,264,871 adult patients were hospitalized for acute medical conditions. In the multivariate analysis, the hospital mortality was significantly higher in low saturated hospitals (adjusted Odds Ratio/aOR = 1.05, 95% CI [1.34-1.07], P < .001), moderate saturated hospitals (aOR = 1.12, 95% CI [1.09-1.14], P < .001), and highly saturated hospitals (aOR = 1.25, 95% CI [1.21-1.30], P < .001) compared to non-saturated hospitals. The proportion of deaths outside ICU was higher in highly saturated hospitals (87%) compared to non-, low- or moderate saturated hospitals (81-84%). The negative impact of hospital saturation on mortality was more pronounced in patients older than 65 years, those with fewer comorbidities (Charlson 1-2 and 3 vs. 0), patients with cancer, nervous and mental diseases, those admitted from home or through the emergency room (compared to transfers from other hospital wards), and those not admitted to the intensive care unit., Conclusions: Our study reveals a noteworthy "dose-effect" relationship: as hospital saturation intensifies, the non-COVID-19 hospital mortality risk also increases. These results raise concerns regarding hospitals' resilience and patient safety, underscoring the importance of identifying targeted strategies to enhance resilience for the future, particularly for high-risk patients., (© 2024.

Background: Limited evidence exists on the influence of hospital procedure volume, socioeconomic status, and comorbidities on surgical abortion outcomes., Objective: Our study aimed to assess the association between hospital procedure volume, individual and neighborhood deprivation, comorbidities, and abortion-related adverse events., Study Design: A nationwide population-based cohort study of all women hospitalized for surgical abortion was conducted from January 1, 2018 to December 31, 2019 in France. Annual hospital procedure volume was categorized into 4 levels based on spline function visualization: very low (<80), low ([80-300]), high ([300-650]), and very high-volume (≥650) centers. The primary outcome was the occurrence of at least one surgical-related adverse event, including hemorrhage, retained products of conception, genital tract and pelvic infection, transfusion, fistulas and neighboring lesions, local hematoma, failure of abortion, and admission to an intensive care unit or death. These events were monitored during the index stay and during a subsequent hospitalization up to 90 days. The secondary outcome encompassed general adverse events not directly linked to surgery., Results: Of the 112,842 hospital stays, 4951 (4.39%) had surgical-related adverse events and 256 (0.23%) had general adverse events. The multivariate analysis showed a volume-outcome relationship, with lower rates of surgical-related adverse events in very high-volume (2.25%, aOR=0.34, 95% CI [0.29-0.39], P<.001), high-volume (4.24%, aOR=0.61, 95% CI [0.55-0.69], P<.001), and low-volume (4.69%, aOR=0.81, 95% CI [0.75-0.88], P<.001) wh en compared to very low-volume centers (6.65%). Individual socioeconomic status (aOR=1.69, 95% CI [1.47-1.94], P<.001), neighborhood deprivation (aOR=1.31, 95% CI [1.22-1.39], P<.001), and comorbidities (aOR=1.79, 95% CI [1.35-2.38], P<.001) were associated with surgical-related adverse events. Conversely, the multivariate analysis of general adverse events did not reveal any volume-outcome relationship., Conclusion: The presence of a volume-outcome relationship underscores the need for enhanced safety standards in low-volume centers to ensure equity in women's safety during surgical abortions. However, our findings also highlight the complexity of this safety concern which involves multiple other factors including socioeconomic status and comorbidities that policymakers must consider., (Copyright © 2024 Elsevier Inc.

To investigate the long-term trends in counseling for stress and depression using data from a nationwide survey in South Korea. We conducted a nationwide serial, large-scale, cross-sectional, survey-based study using data from 2,903,887 Korean adults from the Korea Community Health Survey, 2009-2022. Our study investigated the trends and risk factors for counseling for stress and depression during the pre-pandemic (2009-2019) and pandemic era (2020-2022). The prevalence of counseling for stress and depression increased across pre-pandemic (counseling for stress: β, 0.217 [95 % CI, 0.194 to 0.241]; counseling for depression: β, 0.136 [0.118 to 0.154]) and pandemic periods (β, 0.324 [0.287 to 0.360]; β, 0.210 [0.182 to 0.239], respectively). The prevalence of counseling for stress and depression showed steeper slopes for increasing trends after the outbreak. In addition, subgroups with female sex, urban residence, lower household income, lower self-rated health, shorter sleep time, and higher worries about contracting COVID-19 were the risk factors associated with the increased prevalence of counseling for stress and depression. Our study analyzed the trends in counseling for stress and depression among over two million South Korean adults in 2009-2022, revealing a significant escalation during the pandemic. These findings emphasize the need for mental health policies to support vulnerable groups during the pandemic., Competing Interests: Declaration of competing interest None to declare., (Copyright © 2024 Elsevier B.V.

Background: The fear of clinical errors among healthcare workers (HCW) is an understudied aspect of patient safety. This study aims to describe this phenomenon among HCW and identify associated socio-demographic, professional, burnout and mental health factors., Methods: We conducted a nationwide, online, cross-sectional study targeting HCW in France from May to June 2021. Recruitment was through social networks, professional networks, and email invitations. To assess the fear of making clinical errors, HCW were asked: "During your daily activities, how often are you afraid of making a professional error that could jeopardize patient safety?" Responses were collected on a 7-point Likert-type scale. HCW were categorized into "High Fear" for those who reported experiencing fear frequently ("once a week," "a few times a week," or "every day"), vs. "Low Fear" for less often. We used multivariate logistic regression to analyze associations between fear of clinical errors and various factors, including sociodemographic, professional, burnout, and mental health. Structural equation modeling was used to explore how this fear fits into a comprehensive theoretical framework., Results: We recruited a total of 10,325 HCW, of whom 25.9% reported "High Fear" (95% CI: 25.0-26.7%). Multivariate analysis revealed higher odds of "High Fear" among males, younger individuals, and those with less professional experience. High fear was more notable among physicians and nurses, and those working in critical care and surgery, on night shifts or with irregular schedules. Significant associations were found between "High Fear" and burnout, low professional support, major depressive disorder, and sleep disorders., Conclusions: Fear of clinical errors is associated with factors that also influence patient safety, highlighting the importance of this experience. Incorporating this dimension into patient safety culture assessment could provide valuable insights and could inform ways to proactively enhance patient safety., 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 © 2024 Boyer, Wu, Fernandes, Tran, Brousse, Nguyen, Yon, Auquier, Lucas, Boussat and Fond.)

Background: Burnout and absenteeism are prevalent among healthcare workers, reflecting prolonged work-related stress and dissatisfaction with their job. Identifying poor sleep as a contributing factor can assist in developing targeted interventions. This study explored the relationship between burnout, absenteeism, and sleep among healthcare workers., Methods: A nationwide online cross-sectional study was conducted among healthcare professionals in France during the third wave of COVID-19, from May 2021 to June 2021. Recruitment strategies included outreach through social and professional networks and email invitations. Burnout was assessed using the Maslach Burnout Inventory, absenteeism through self-reported days absent in the preceding 12 months, and sleep quality using the Pittsburgh Sleep Quality Index. The association between burnout, absenteeism, and poor sleep was analyzed using multivariate logistic regression, accounting for individual and professional variables. The study also explored various sleep dimension abnormalities., Results: Of 10,087 healthcare workers, 55.2 % reported burnout, 20.5 % absenteeism, and 64.8 % poor sleep. Burnout and absenteeism were more frequent in individuals with poor sleep compared to those with good sleep (74.2 % vs. 25.8 % and 75.6 % vs. 24.4 %, respectively). The multivariate analyses confirmed the associations between burnout, absenteeism, and poor sleep (Adjusted Odds Ratio [aOR] = 2.15, 95 % CI [1.97-2.35], p < 0.001; and aOR = 1.49, 95 % CI [1.32-1.67], p < 0.001, respectively)., Interpretation: The study highlighted the intricate relationship between burnout, absenteeism, and poor sleep among healthcare professionals, informing workforce management and policy decisions to foster a supportive work environment and enhance their well-being., Competing Interests: Declaration of competing interest None., (Copyright © 2024.

Aim: The anticholinergic properties of medications are associated with poorer cognitive performance in schizophrenia. Numerous scales have been developed to assess anticholinergic burden and yet, there is no consensus indicating which anticholinergic burden scale is more relevant for patients with schizophrenia. We aimed to identify valid scales for estimating the risk of iatrogenic cognitive impairment in schizophrenia., Methods: We identified 27 scales in a literature review. The responses to neuropsychological tests of 839 individuals with schizophrenia or schizoaffective disorder in the FACE-SZ database were collected between 2010 and 2021. We estimated the association between objective global cognitive performance and the 27 scales, the number of psychotropic drugs, and chlorpromazine and lorazepam equivalents in bivariable regressions in a cross-sectional design. We then adjusted the bivariable models with covariates: the predictors significantly associated with cognitive performance in multiple linear regressions were considered to have good concurrent validity to assess cognitive performance., Results: Eight scales, the number of psychotropic drugs, and drug equivalents were significantly associated with cognitive impairment. The number of psychotropic drugs, the most convenient predictor to compute, was associated with worse executive function (Standardized β = -0.12, p = .004) and reasoning (Standardized β = -0.08, p = .037)., Conclusion: Anticholinergic burden, the number of psychotropic drugs, and drug equivalents were weakly associated with cognition, thus suggesting that cognitive impairment in schizophrenia and schizoaffective disorder is explained by factors other than medication. The number of psychotropic drugs was the most parsimonious method to assess the risk of iatrogenic cognitive impairment., 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 © 2024 Vidal, Roux, Urbach, Belmonte, Boyer, Capdevielle, Clauss-Kobayashi, D’Amato, Dassing, Dubertret, Dubreucq, Fond, Honciuc, Leignier, Llorca, Mallet, Misdrahi, Pignon, Rey, Schürhoff, Tessier, the FACE-SZ (FondaMental Academic Centers of Expertise—Schizophrenia) Group, Passerieux and Brunet-Gouet.)

Delirium is a common condition across different settings and populations. The interventions for preventing and managing this condition are still poorly known. The aim of this umbrella review is to synthesize and grade all preventative and therapeutic interventions for delirium. We searched five databases from database inception up to March 15th, 2023 and we included meta-analyses of randomized controlled trials (RCTs) to decrease the risk of/the severity of delirium. From 1959 records after deduplication, we included 59 systematic reviews with meta-analyses, providing 110 meta-analytic estimates across populations, interventions, outcomes, settings, and age groups (485 unique RCTs, 172,045 participants). In surgery setting, for preventing delirium, high GRADE evidence supported dexmedetomidine (RR=0.53; 95%CI: 0.46-0.67, k=13, N=3988) and comprehensive geriatric assessment (OR=0.46; 95%CI=0.32-0.67, k=3, N=496) in older adults, dexmedetomidine in adults (RR=0.33, 95%CI=0.24-0.45, k=7, N=1974), A2-adrenergic agonists after induction of anesthesia (OR= 0.28, 95%CI= 0.19-0.40, k=10, N=669) in children. High certainty evidence did not support melatonergic agents in older adults for delirium prevention. Moderate certainty supported the effect of dexmedetomidine in adults and children (k=4), various non-pharmacological interventions in adults and older people (k=4), second-generation antipsychotics in adults and mixed age groups (k=3), EEG-guided anesthesia in adults (k=2), mixed pharmacological interventions (k=1), five other specific pharmacological interventions in children (k=1 each). In conclusion, our work indicates that effective treatments to prevent delirium differ across populations, settings, and age groups. Results inform future guidelines to prevent or treat delirium, accounting for safety and costs of interventions.

Transcranial direct current stimulation (tDCS), which delivers a direct current to the brain, emerged as a non-invasive potential therapeutic in treating a range of neurological and neuropsychiatric disorders. However, a comprehensive quantitative evidence synthesis on the effects of tDCS on a broad range of mental illnesses is lacking. Here, we systematically assess the certainty of the effects and safety of tDCS on several health outcomes using an umbrella review of randomized controlled trials (RCTs). The methodological quality of each included original meta-analysis was assessed by the A Measurement Tool for Assessing Systematic Reviews 2 (AMSTAR2), and the certainty of the evidence for each effect was evaluated with Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). We followed an a priori protocol (PROSPERO CRD42023458700). We identified 15 meta-analyses of RCTs (AMSTAR 2; high 3, moderate 3, and low 9) that included 282 original articles, covering 22 unique health endpoints across 22 countries and six continents. From meta-analyses of RCTs supported by very low to high certainty of evidence, it was found that tDCS improved symptoms related to post-stroke, including post-stroke depression scale score (equivalent standardized mean difference [eSMD], 1.61 [95% confidence level, 0.72-2.50]; GRADE=moderate), activities of daily living independence (7.04 [3.41-10.67]; GRADE=high), motor recovery of upper and lower extremity (upper extremity: 0.15 [0.06-0.24], GRADE=high; lower extremity: 0.10 [0.03-0.16], GRADE=high), swallowing performance (GRADE=low), and spasticity (GRADE=moderate). In addition, tDCS had treatment effects on symptoms of several neurological and neuropsychiatric disorders, including obsessive-compulsive disorder (0.81 [0.44-1.18]; GRADE=high), pain in fibromyalgia (GRADE=low), disease of consciousness (GRADE=low), insight score (GRADE=moderate) and working memory (0.34 [0.01-0.67]; GRADE=high) in schizophrenia, migraine-related pain (-1.52 [-2.91 to -0.13]; GRADE=high), attention-deficit/hyperactivity disorder (reduction in overall symptom severity: 0.24 [0.04-0.45], GRADE=low; reduction in inattention: 0.56 [0.02-1.11], GRADE=low; reduction in impulsivity: 0.28 [0.04-0.51], GRADE=low), depression (GRADE=low), cerebellar ataxia (GRADE=low), and pain (GRADE=very low). Importantly, tDCS induced an increased number of reported cases of treatment-emergent mania or hypomania (0.88 [0.62-1.13]; GRADE=moderate). We found varied levels of evidence for the effects of tDCS with multiple neurological and neuropsychiatric conditions, from very low to high certainty of evidence. tDCS was effective for people with stroke, obsessive-compulsive disorder, fibromyalgia, disease of consciousness, schizophrenia, migraine, attention-deficit/hyperactivity disorder, depression, cerebellar ataxia, and pain. Therefore, these findings suggest the benefit of tDCS for several neurological and neuropsychiatric disorders; however, further studies are needed to understand the underlying mechanism and optimize its therapeutic potential., (© 2024.

Background: Suicide is the second-leading cause of death among adolescents and is associated with clusters of suicides. Despite numerous studies on this preventable cause of death, the focus has primarily been on single nations and traditional statistical methods., Objective: This study aims to develop a predictive model for adolescent suicidal thinking using multinational data sets and machine learning (ML)., Methods: We used data from the Korea Youth Risk Behavior Web-based Survey with 566,875 adolescents aged between 13 and 18 years and conducted external validation using the Youth Risk Behavior Survey with 103,874 adolescents and Norway's University National General Survey with 19,574 adolescents. Several tree-based ML models were developed, and feature importance and Shapley additive explanations values were analyzed to identify risk factors for adolescent suicidal thinking., Results: When trained on the Korea Youth Risk Behavior Web-based Survey data from South Korea with a 95% CI, the XGBoost model reported an area under the receiver operating characteristic (AUROC) curve of 90.06% (95% CI 89.97-90.16), displaying superior performance compared to other models. For external validation using the Youth Risk Behavior Survey data from the United States and the University National General Survey from Norway, the XGBoost model achieved AUROCs of 83.09% and 81.27%, respectively. Across all data sets, XGBoost consistently outperformed the other models with the highest AUROC score, and was selected as the optimal model. In terms of predictors of suicidal thinking, feelings of sadness and despair were the most influential, accounting for 57.4% of the impact, followed by stress status at 19.8%. This was followed by age (5.7%), household income (4%), academic achievement (3.4%), sex (2.1%), and others, which contributed less than 2% each., Conclusions: This study used ML by integrating diverse data sets from 3 countries to address adolescent suicide. The findings highlight the important role of emotional health indicators in predicting suicidal thinking among adolescents. Specifically, sadness and despair were identified as the most significant predictors, followed by stressful conditions and age. These findings emphasize the critical need for early diagnosis and prevention of mental health issues during adolescence., (©Hyejun Kim, Yejun Son, Hojae Lee, Jiseung Kang, Ahmed Hammoodi, Yujin Choi, Hyeon Jin Kim, Hayeon Lee, Guillaume Fond, Laurent Boyer, Rosie Kwon, Selin Woo, Dong Keon Yon.

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., Objective: This study is part of the Patient-Reported Experience Measure for Improving Quality of Care in Mental Health (PREMIUM) project and aims to establish an item bank (PREMIUM-CE) and to develop computerized adaptive tests (CATs) to measure the experience of the care environment of adult patients with schizophrenia, bipolar disorder, or major depressive disorder., Methods: We performed psychometric analyses including assessments of item response theory (IRT) model assumptions, IRT model fit, differential item functioning (DIF), item bank validity, and CAT simulations., Results: In this multicenter cross-sectional study, 498 patients were recruited from outpatient and inpatient settings. The final PREMIUM-CE 13-item bank was sufficiently unidimensional (root mean square error of approximation=0.082, 95% CI 0.067-0.097; comparative fit index=0.974; Tucker-Lewis index=0.968) and showed an adequate fit to the IRT model (infit mean square statistic ranging between 0.7 and 1.0). DIF analysis revealed no item biases according to gender, health care settings, diagnosis, or mode of study participation. PREMIUM-CE scores correlated strongly with satisfaction measures (r=0.69-0.78; P<.001) and weakly with quality-of-life measures (r=0.11-0.21; P<.001). CAT simulations showed a strong correlation (r=0.98) between CAT scores and those of the full item bank, and around 79.5% (396/498) of the participants obtained a reliable score with the administration of an average of 7 items., Conclusions: The PREMIUM-CE item bank and its CAT version have shown excellent psychometric properties, making them reliable measures for evaluating the patient experience of the care environment among adults with severe mental illness in both outpatient and inpatient settings. These measures are a valuable addition to the existing landscape of patient experience assessment, capturing what truly matters to patients and enhancing the understanding of their care experiences., Trial Registration: ClinicalTrials.gov NCT02491866; https://clinicaltrials.gov/study/NCT02491866., (©Sara Fernandes, Yann Brousse, Xavier Zendjidjian, Delphine Cano, Jérémie Riedberger, Pierre-Michel Llorca, Ludovic Samalin, Daniel Dassa, Christian Trichard, Vincent Laprevote, Anne Sauvaget, Mocrane Abbar, David Misdrahi, Fabrice Berna, Christophe Lancon, Nathalie Coulon, Wissam El-Hage, Pierre-Emmanuel Rozier, Michel Benoit, Bruno Giordana, Alejandra Caqueo-Urízar, Dong Keon Yon, Bach Tran, Pascal Auquier, Guillaume Fond, Laurent Boyer.
