RESUMEN
OBJECTIVE: Less is known concerning the evolution of coping strategies before and after deep brain stimulation (DBS) in Parkinson's disease (PD) patients. METHODS: In a randomized controlled trial, coping was measured with the neurological version of the CHIP (Coping with Health Injuries and Problem) and the BriefCOPE in PD patients before ( T1: DBS - 2 months) and after (T2: + 3 months, T3: + 6 months) DBS. Patients (N = 50, age 59 ± 5.7 years, disease duration 9.54 ± 3.7 years) were randomised in 3 groups: CRTG (preoperative psychological preparation with cognitive restructuring), PIG (preoperative non structured interviews), and CG (no psychological preparation). RESULTS: Coping strategies are modulated by the time of evaluation. Some strategies are significantly more used preoperatively than postoperatively, as strategies about the research for information (CHIP: F = 16.14; P = .000; η2 = .095; BriefCOPE F = 5.71; P = .005; η2 = .066), emotional regulation (F = 3.29; P = .042; η2 = .029), and well-being searching (F = 4.59; P = .013; η2 = .043). Some other strategies appear more used post than preoperatively, as palliative coping (F = 5.57; P = .005; η2 = .064), humour (F = 3.35; P = .041; η2 = .0.35), and use of substance (F = 4.43; P = .015; η2 = .070). No other specific time, group or time per group interaction effect was found. CONCLUSION: Coping strategies are crucial for PD patients to adapt to the evolution of their parkinsonian state. Their consideration should be more systematic in the neurosurgical process, particularly when neurological symptoms would remain after DBS. More insights are needed concerning the evolution of coping strategies through DBS and the impact of a preoperative psychotherapy over them in preoperative PD patients.
RESUMEN
Parkinson's disease (PD) is a neurodegenerative disease, that combines motor and non-motor disorders, and alters patients' autonomy. Even if subthalamic nucleus deep brain stimulation (STN-DBS) induces undisputable motor improvement, a post-operative social maladjustment was described by some patients. Our aim was to describe pre-operative illness perceptions in parkinsonian patients, and to determine the possible impact of cognitive restructuration over them. We analyzed 27 parkinsonian patient's candidates to DBS. The mean age was 59 ± 5.94 years, and mean disease duration was 9.89 ± 4.15 years. The patients had two pre-operative psychological interviews (DBS-45 days, DBS-25 days) and completed the Illness Perception Questionnaire-Revised (IPQ-R) before the first interview and at DBS-1 day. The CRTG group (n = 13) had cognitive restructuration during second interview, on dysfunctional cognitions about their perception of post-DBS life which emerged from the first interview. The PIG group (n = 14) benefited of two non-structured interviews. No significant differences were found between the visits (DBS-45 days, DBS-1 day) for IPQ-R dimensions, except for the perception of "personal control" over PD which appears significantly higher for CRTG than PIG group (p = .039) at DBS-1 day, whereas the scores were quite similar at DBS-45 days. Illness perceptions seem to be stable over time and mostly influenced by disease experience of PD. However, the perception of personal control over PD seemed to be modulated through cognitive restructuration, giving patients' control back over disease. Before DBS, illness perceptions investigation and restructuration constitute an interesting point to work on, to enhance perceived benefits of neurosurgery.Trial registration: Clinical Research Program, N°IDRCB 2008-A00655-50, approved by the local ethics committee (CPP EST III, N° CPP: 08.07.03, first version date: 04/01/2008), registered on the ClinicalTrials.gov website (NCT02893449).

Mania is characterized by affective and cognitive alterations, with heightened external and self-awareness that are opposite to the alteration of awareness during epileptic seizures. Electrical stimulations carried out routinely during stereotactic intracerebral EEG (SEEG) recordings for presurgical evaluation of epilepsy may represent a unique opportunity to study the pathophysiology of such complex emotional-behavioral phenomenon, particularly difficult to reproduce in experimental setting. We investigated SEEG signals-based functional connectivity between different brain regions involved in emotions and in consciousness processing during a manic state induced by electrical stimulation in a patient with drug-resistant focal epilepsy. The stimulation inducing manic state and an asymptomatic stimulation of the same site, as well as a seizure with alteration of awareness (AOA) were analyzed. Functional connectivity analysis was performed by measuring interdependencies (nonlinear regression analysis based on the h2 coefficient) between broadband SEEG signals and within typical sub-bands, before and after stimulation, or before and during the seizure with AOA, respectively. Stimulation of the right lateral prefrontal cortex induced a manic state lasting several hours. Its onset was associated with significant increase of broadband-signal functional coupling between the right hemispheric limbic nodes, the temporal pole and the claustrum, whereas significant decorrelation between the right lateral prefrontal and the anterior cingulate cortex was observed in theta-band. In contrast, ictal alteration of awareness was associated with increased broadband and sub-bands synchronization within and between the internal and external awareness networks, including the anterior and middle cingulate, the mesial and lateral prefrontal, the inferior parietal and the temporopolar cortex. Our data suggest the existence of network- and frequency-specific functional connectivity patterns during manic state. A transient desynchronization of theta activity between the external and internal awareness network hubs is likely to increase awareness, with potential therapeutic effect.

BACKGROUND: Schizophrenia is associated with severe cognitive deficits, particularly episodic memory deficits, that interfere with patients' socio-professional functioning. Retrieval practice (also known as testing effect) is a well-established episodic memory strategy that involves taking an initial memory test on a previously learned material. Testing later produces robust long-term memory improvements in comparison to the restudy of the same material both in healthy subjects and in some clinical populations with memory deficits. While retrieval practice might represent a relevant cognitive remediation strategy in patients with schizophrenia, studies using optimal procedures to explore the benefits of retrieval practice in this population are still lacking. Therefore, the purpose of our study was to investigate the benefits of retrieval practice in patients with schizophrenia. METHODS: Nineteen stabilised outpatients with schizophrenia (DSM-5 criteria) and 20 healthy controls first studied a list of 60 word-pairs (30 pairs with weak semantic association and 30 non associated pairs). Half the pairs were studied again (restudy condition), while only the first word of the pair was presented and the subject had to recall the second word for the other half (retrieval practice condition). The final memory test consisted in a cued-recall which took place 2 days later. Statistical analyses were performed using Bayesian methods. RESULTS: Cognitive performances were globally altered in patients. However, in both groups, memory performances for word-pairs were significantly better after retrieval practice than after restudy (56.1% vs 35.7%, respectively, Pr(RP > RS) > 0.999), and when a weak semantic association was present (64.7% vs 27.1%, respectively; Pr(weak > no) > 0.999). Moreover, the positive effect of RP was observed in all patients but one. CONCLUSIONS: Our study is the first to demonstrate that retrieval practice efficiently improves episodic memory in comparison to restudy in patients with schizophrenia. This learning strategy should therefore be considered as a useful tool for cognitive remediation programs. In this perspective, future studies might explore retrieval practice using more ecological material.

BACKGROUND: Major depressive disorder (MDD) is underdiagnosed and undertreated in schizophrenia, and has been strongly associated with impaired quality of life.AimsTo determine the prevalence and associated factors of MDD and unremitted MDD in schizophrenia, to compare treated and non-treated MDD. METHOD: Participants were included in the FondaMental Expert Centers for Schizophrenia and received a thorough clinical assessment. MDD was defined by a Calgary score ≥6. Non-remitted MDD was defined by current antidepressant treatment (unchanged for >8 weeks) and current Calgary score ≥6. RESULTS: 613 patients were included and 175 (28.5%) were identified with current MDD. MDD has been significantly associated with respectively paranoid delusion (odds ratio 1.8; P = 0.01), avolition (odds ratio 1.8; P = 0.02), blunted affect (odds ratio 1.7; P = 0.04) and benzodiazepine consumption (odds ratio 1.8; P = 0.02). Antidepressants were associated with lower depressive symptoms score (5.4 v. 9.5; P < 0.0001); however, 44.1% of treated patients remained in non-remittance MDD. Nonremitters were found to have more paranoid delusion (odds ratio 2.3; P = 0.009) and more current alcohol misuse disorder (odds ratio 4.8; P = 0.04). No antidepressant class or specific antipsychotic were associated with higher or lower response to antidepressant treatment. MDD was associated with Metabolic syndrome (31.4 v. 20.2%; P = 0.006) but not with increased C-reactive protein. CONCLUSIONS: Antidepressant administration is associated with lower depressive symptom level in patients with schizophrenia and MDD. Paranoid delusions and alcohol misuse disorder should be specifically explored and treated in cases of non-remission under treatment. MetS may play a role in MDD onset and/or maintenance in patients with schizophrenia.Declaration of interestNone.

In a perspective of personalized care for smoking cessation, a better clinical characterization of smokers with schizophrenia (SZ) is needed. The objective of this study was to determine the clinical characteristics of SZ smokers with severe nicotine (NIC) dependence. 240 stabilized community-dwelling SZ smokers (mean age = 31.9 years, 80.4% male gender) were consecutively included in the network of the FondaMental Expert Centers for Schizophrenia and assessed with validated scales. Severe NIC dependence was defined by a Fagerstrom questionnaire score ≥ 7. Depression was defined by a Calgary score ≥ 6. Childhood trauma was self-reported by the Childhood Trauma Questionnaire score (CTQ). Ongoing psychotropic treatment was recorded. Severe NIC dependence was identified in 83 subjects (34.6%), depression in 60 (26.3%). 44 (22.3%) subjects were treated by antidepressants. In a multivariate model, severe NIC dependence remained associated with depression (OR = 3.2, p = 0.006), male gender (OR = 4.5, p = 0.009) and more slightly with childhood trauma (OR = 1.03, p = 0.044), independently of socio-demographic characteristics, psychotic symptoms severity, psychotropic treatments and alcohol disorder. NIC dependence was independently and strongly associated with, respectively, depression and male gender in schizophrenia, and only slightly with history of childhood trauma. Based on these results, the care of both nicotine dependence and depression should be evaluated for an effective smoking cessation intervention in schizophrenia.

BACKGROUND: Catatonia is a neuropsychiatric syndrome with motor and behavioural symptoms. Though usually occurring in patients with schizophrenia and mood disorders, this syndrome may also be associated with neurological diseases or general medical conditions. Few cases of catatonia associated with autoimmune disorders have been described. CASE PRESENTATION: Here, we report the case of a 27-year-old woman diagnosed with Hashimoto's encephalitis (HE) who attempted suicide and infanticide by defenestration. As she presented risk factors for postpartum psychosis, she was treated principally with antipsychotics. Despite adequate treatment for psychosis, symptoms worsened and she developed catatonia. Complementary investigations showed elevated titres of anti-thyroglobulin and anti-thyroperoxidase antibodies (200 and 10 times, respectively, as compared to normal levels) and electroencephalography were suggestive of encephalopathy. In the presence of an otherwise unexplained neuropsychiatric condition, HE was suspected and oral prednisolone was introduced. Psychiatric symptoms improved dramatically within 72 h and the patient was still free of any symptom 3 years later. CONCLUSION: Catatonia of organic aetiology should always be considered before a psychiatric aetiology especially in case of clinical worsening in spite of adequate psychotropic treatment. To our knowledge, this is the first description of catatonia associated with HE.

Re-reading is the most common learning strategy, albeit not a very efficient one. Testing is highly efficient, but not perceived by students as a learning strategy. Prospective judgment-of-learning (JOL) reflect the learner's impression of subsequently being able to retrieve the ongoing learning in a cued-recall task. Estimating JOL involves attempting to retrieve the information, as in testing. The few studies that have explored the potential mnemonic benefit of JOL have yielded contradictory results. Our aim was to compare JOL and testing with re-study and to examine the impact of these strategies according to the relative difficulty of the material (cue-target association strength) in two experiments. After a first encoding phase, participants re-studied, provided JOL, or took a test. Forty-eight hours later, they participated in a final cued-recall test, during which their confidence level judgments were collected. The main result was that delayed JOL behaved in the same way as testing, and both yielded better performances than re-study when material was of moderate difficulty. The easy or very difficult material revealed no differences between these strategies. JOL is proposed as an alternative to testing when faced with difficult material.

BACKGROUND: Suicidal behaviour and deliberate self-harm are common among adults. Research indicates that maintaining contact either via letter or postcard with at-risk adults following discharge from care services can reduce reattempt risk. Feasibility trials demonstrated that intervention through text message was also effective in preventing suicide repetition amongst suicide attempters. The aim of the current study is to investigate the effect of text message intervention versus traditional treatment on reducing the risk of suicide attempt repetition among adults after self-harm. METHODS/DESIGN: The study will be a 2-year multicentric randomized controlled trial conducted by the Brest University Hospital, France. Participants will be adults discharged after self-harm, from emergency services or after a short hospitalization. Participants will be recruited over a 12-month period. The intervention is comprised of an SMS that will be sent at h48, D7, D15 and monthly. The text message enquires about the patients' well-being and includes information regarding individual sources of help and evidence-based self help strategies. Participants will be assessed at the baseline, month 6 and 13. As primary endpoint, we will assess the number of patients who reattempt suicide in each group at 6 months. As secondary endpoints, we will assess the number of patients who reattempt suicide at 13 month, the number of suicide attempts in the intervention and control groups at 6 and 13 month, the number of death by suicide in the intervention and control groups at month 6 and 13. In both groups, suicidal ideations, will be assessed at the baseline, month 6 and 13. Medical costs and satisfaction will be assessed at month 13. DISCUSSION: This paper describes the design and deployment of a trial SIAM; an easily reproducible intervention that aims to reduce suicide risk in adults after self-harm. It utilizes several characteristics of interventions that have shown a significant reduction in the number of suicide reattempts. We propose to assess its efficacy in reducing suicide reattempt in the suicide attempter (SA) population. TRIAL REGISTRATION: The study was registered on Clinical Trials Registry (clinicaltrials.gov): NCT02106949, registered on 06 June 2014.

Background: Healthcare workers' mental health has been impacted by the COVID-19 pandemic, emphasizing the need for mental health interventions in this population. Online cognitive behavioral therapy (CBT) is efficient to reduce stress and may reach numerous professionals. We developed "MyHealthToo", an online CBT program to help reduce stress among healthcare workers during the COVID-19 pandemic. Objective: The aim of our study is to investigate the efficacy of an online CBT program on stress and mental health conditions among healthcare workers during a health crisis. Methods: We performed a multicentric randomized controlled trial among 155 participants allocated either to the experimental or active control group (bibliotherapy). The primary outcome was the decrease of perceived stress scores (PSS-10) post-treatment. Secondary outcomes included depression, insomnia and PTSD symptoms along with self-reported resilience and ruminations. Assessments were scheduled pretreatment, mid-treatment (4 weeks), post-treatment (8 weeks), and at 1-month and 4-months follow-up. Results: For both interventions, mean changes on the PSS-10 were significant post-therapy (W8), as at 1-month (W12) and 4-months (W24) follow-ups. The between-group comparison showed no difference at any time point (ps > 0.88). Work-related ruminations significantly decreased in the experimental group with a significant between-group difference at W8 (Δ = -1.83 [-3.57; -0.09], p = 0.04). Posttraumatic stress symptoms significantly decreased in the experimental group with a significant between-group difference at W12 (Δ = -1.41 [-2.68; -0.14], p = 0.03). The decrease in work-related ruminations at W8 mediated the decrease in posttraumatic stress symptoms at W12 (p = 0.048). Conclusion: The "MyHealthToo" online CBT intervention may help reduce ruminations about work and posttraumatic stress symptoms among healthcare workers during a major health crisis. Work-related ruminations may represent a relevant target of online interventions to improve mental health among healthcare workers.
RESUMEN
Psychosis is more common in people with temporal lobe epilepsy than it is in the general population. Treatment can be difficult in these patients because of the complex interactions between antipsychotic and antiepileptic drugs. Some antipsychotic drugs also decrease the seizure threshold. We report the case of a 49-year-old man with a hypothalamic hamartoma, with a history of both gelastic and temporal lobe seizures. The patient was rendered seizure-free after three neurosurgical procedures but developed a drug-resistant paranoid psychosis. He was treated with electroconvulsive therapy (ECT). After two weeks with six stimulations that resulted in seizures, the psychiatric phenomena disappeared completely. There was no relapse of either the psychiatric symptoms or the seizures during the 42 months of follow-up. This case report suggests that ECT might be safe for psychosis in patients with a history of seizures that have previously been successfully treated with neurosurgery, although caution should be exercised in drawing general conclusions from a single case report.

Background: Police personnel are among the first responders exposed to terrorist attacks, raising in number in the late decades. Due to their profession, they are also exposed to repetitive violence, increasing their vulnerability to PTSD and depression.Objective: Our study aims at comparing the prevalence of PTSD and depression, and the risk factors associated with these conditions among directly and indirectly exposed versus non-exposed police personnel during the Strasbourg Christmas Market terrorist attack.Method: Three months after the attack, participants completed a survey assessing their sociodemographic characteristics, occupational data, degree of exposure, sleep debt around the event, event centrality (CES), and three mental health conditions: PTSD (PCL-5), depression (PHQ-9), and suicide risk (yes/no questions).Results: A total of 475 police personnel responded to the questionnaire: 263 were exposed to the attack (182 of them directly) and 212 were non-exposed. Among directly exposed participants, the prevalences of partial and complete PTSD were 12.6 and 6.6%, and the prevalence of moderate-to-severe depression was 11.5%. Multivariate analysis revealed that direct exposure was associated with a higher risk of PTSD (OR = 2.98 [1.10-8.12], p = .03). Direct exposure was not associated with a higher risk of depression (OR = 0.40 [0.10-1.10], p = .08). A significant sleep debt after the event was not associated with a higher risk of later PTSD (OR = 2.18 [0.81-5.91], p = .13) but was associated with depression (OR = 7.92 [2.40-26.5], p < .001). A higher event centrality was associated with both PTSD and depression (p < .001).Conclusions: Police personnel directly exposed to the Strasbourg Christmas Market terrorist attack were at higher risk of PTSD but not depression. Efforts to prevent and treat PTSD should focus on directly exposed police personnel. However, general mental health should be monitored for every personnel member.
Direct exposure to the terrorist attack and gender (female) were significantly associated with a higher risk of PTSD among police personnel.Sleep debt after the attack was significantly associated with depression but not with PTSD.No occupational factor was associated with either PTSD or depression.Both PTSD and depression were significantly associated with a higher suicide risk.A higher event centrality was significantly associated with direct exposure and a higher risk of both PTSD and depression.

Background: Stressful events during a pandemic are a major cause of serious health problems, such as burnout, depression and posttraumatic stress disorder (PTSD) among health care workers (HCWs). During three years, HCWs, on the frontline to fight the COVID-19 pandemic, have been at an increased risk of high levels of stress, anxiety, depression, burnout and PTSD. Regarding potential psychological interventions, Eye Movement Desensitization & Reprocessing (EMDR) is a structured, strongly recommended therapy based on its well-known efficacy in reducing PTSD symptoms and anxiety.Objectives: This study, designed as a trial within a cohort (TwiC), aims to 1) estimate the prevalence of depression, burnout and PTSD in a sample of HCWs after experiencing the COVID-19 emergency (cohort part) and 2) assess the efficacy and acceptability of 'EMDR + usual care' for HCWs from the cohort who report significant psychological symptoms (trial part).Methods: The study, designed as a TwiC, consists of a prospective cohort study (n = 3000) with an embedded, pragmatic, randomized open-label superiority trial with two groups (n = 900). Participants included in the trial part are HCWs recruited for the cohort with significant symptoms on at least one psychological dimension (depression, burnout, PTSD) at baseline, 3 months or 6 months, determined by using the Patient Health Questionnaire (PHQ-9), Professional Quality of Life (ProQOL) scale, and PTSD Checklist for the DSM-5 (PCL-5). The intervention consists of 12 separate EMDR sessions with a certified therapist. The control group receives usual care. The trial has three primary outcomes: changes in depression, burnout and PTSD scores from randomization to 6 months. All participants are followed up for 12 months.Conclusions: This study provides empirical evidence about the impact of the COVID-19 pandemic and the mental health burden it places on HCWs and assesses the effectiveness of EMDR as a psychological intervention.Trial registration NCT04570202.
Health care workers are at increased risk of stress, anxiety, depression, burnout and PTSD following the COVID-19 pandemic.In this study, the effectiveness of EMDR in reducing depression, burnout and PTSD in health care workers exposed to COVID-19 is investigated.In this study, an original 'trial within a cohort' (TwiC) design that consists of a cohort study with an embedded pragmatic randomized trial is used.The study is fully web-based, including online screening, consent and assessments.

Schizophrenia is a severe mental illness, which affects sense of identity. While the ability to have a coherent vision of the self (i.e., self-images) relies partly on its reciprocal relationships with autobiographical memories, little is known about how memories ground "self-images" in schizophrenia. Twenty-five patients with schizophrenia and 25 controls were asked to give six autobiographical memories related to four self-statements they considered essential for defining their identity. Results showed that patients' self-images were more passive than those of controls. Autobiographical memories underlying self-images were less thematically linked to these self-images in patients. We also found evidence of a weakened sense of self and a deficient organization of autobiographical memories grounding the self in schizophrenia. These abnormalities may account for the poor cohesiveness of the self in schizophrenia.

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.
RESUMEN
Cognition has become a target for therapeutic intervention and favoring arousal could be a way to help patients. Working memory is an arousal dependent cognitive function. This study used functional MRI (fMRI) as a surrogate marker of working memory to evaluate the sensitivity of patients' hypoactive regions to arousal in a subpopulation of rehabilitated patients. Are hypoactive regions sensitive to arousal? Does the deficit result from arousal deficit or improper coupling with cognitive activity? Eighteen patients and matched controls were recruited. Participants performed a working memory task during combined electroencephalographic (EEG) and fMRI measurements. Cortical regions sensitive to arousal were defined as those which were inversely correlated with low EEG frequencies. Overlap between the arousal-sensitive and hypoactive regions was assessed by mutual information. Arousal-cognitive coupling was evaluated by the correlation between the arousal effect and the task effect. In the patient group, most hypoactive voxels were sensitive to arousal and corresponded to the prefronto-parietal network. But patients had no arousal deficit. Although arousal seems to improve cognitive activity in most of the patients' cortical areas, this coupling appears to be specifically disturbed in their hypoactive regions. In conclusion, although increasing arousal may help cognition, it may do so in an unspecific way.

The Coronavirus Disease 2019 (COVID-19) pandemic exposed health professionals to high stress levels inducing significant psychological impact. Our region, Grand Est, was the most impacted French region during the first COVID-19 wave. In this context, we created CoviPsyHUS, local mental health prevention and care system dedicated explicitly to healthcare workers affected by the COVID-19 pandemic in one of this region's tertiary hospitals. We deployed CoviPsyHUS gradually in 1 month. To date, CoviPsyHUS comprises 60 mental health professionals dedicated to 4 complementary components: (i) a mental health support hotline (170 calls), (ii) relaxation rooms (used by 2,120 healthcare workers with 110 therapeutic workshops offered), (iii) mobile teams (1,200 contacts with healthcare staff), and (iv) a section dedicated to patients and their families. Among the critical points to integrate mental health care system during a crisis, we identified: (i) massive dissemination of mental health support information with multimodal communication, (ii) clear identification of the mental health support system, (iii) proactive mobile teams to identify healthcare professionals in difficulty, (iv) concrete measures to relieve the healthcare professionals under pressure (e.g., the relay in communication with families), (v) support for primary needs (body care (physiotherapy), advice and first-line therapy for sleep disorders), and (vi) psychoeducation and emotion management techniques. The different components of CoviPsyHUS are vital elements in meeting the needs of caregivers in situations of continuous stress. The organization of 4 targeted, modular, and rapidly deployable components makes CoviPsyHUS an innovative, reactive, and replicable mental health prevention and care system that could serve as a universal support model for other COVID-19 affected teams or other exceptional health crises in the future.
RESUMEN
INTRODUCTION: Simulation workshops for surgical training of residents are becoming popular. The gold standard for teaching thoracolumbar pedicle screw placement are cadaver labs; however, the availability of human bodies is limited. The primary objective of this study was to determine if training on a synthetic bone model improves the apprenticeship of accurate pedicle screw placement. The secondary objective was to check the influence of residents' previous experience in spine surgery. HYPOTHESIS: The main hypothesis was that theoretical learning with practical application on synthetic bone was superior to theoretical learning alone. METHODS: Twenty-three orthopedic residents were taught about free-hand pedicle screw placement using a theoretical presentation. Six residents had previous experience with screwing techniques. After randomization in two groups, 11 residents (group 1) participated in a workshop on synthetic bone, whereas 12 residents received only theoretical instruction (group 2). Each resident was asked to place two thoracic screws (T7-T11) and two lumbar screws (L1-L5) on a cadaver. Screw placement accuracy was analyzed using the Gertzbein classification on computed tomography (grades 0 and 1=accurate positioning; grades 2 and 3=malposition>2mm). RESULTS: Rates of accurate screw positioning were 64.0% and 62.5% for thoracic levels, and 72.7% and 66.6% for lumbar levels in group 1 and 2, respectively. There was no significant difference in malposition rates on cadavers between the groups (p=0.1809). A resident who was first trained by simulation had a chance of decreasing the Gertzbein score with an odds-ratio of 1.7714 [0.7710-4.1515]. The odds ratio was 4.5188 [0.0456-0.8451] when comparing residents with previous experience in spinal surgery to novice residents. DISCUSSION: Theoretical teaching associated with a simulation model is relevant for learning a surgical technique. A single simulation workshop on synthetic bone seems insufficient to improve pedicle screw placement accuracy compared to theoretical teaching alone. Progressive experience and the repetition of technical gestures during hands-on supervised learning in spine surgery with a senior surgeon had an influence on the accuracy of pedicle screw placement. LEVEL OF EVIDENCE: II.

On December 11, 2018, five people were killed and 11 injured during a terrorist attack on Strasbourg's Christmas market. As the attacker was on the run during the night, part of the population was locked down for several hours. Our study aimed at assessing factors associated with the development of PTSD and health services use among the victims. Four hundred and twelve victims were followed up from 6 to 11 months after the attacks through phone calls by psychologists. The presence of probable PTSD was assessed with the Trauma Screening Questionnaire. In addition, we evaluated the type and level of exposure, and health services use after the attacks. Two hundred and twelve participants completed the phone interview. The prevalence of probable PTSD was 26.4%. Being locked down during the attack and the level of exposure were associated with probable PTSD (OR = 2.32 [1.17-4.59], p = 0.016 and OR = 1.49 [1.10-2.03], p = 0.010 respectively). Lockdown was especially associated with symptoms suggesting adrenergic hyperactivation (startle at surprise, dreams about the event). General and mental health services use was frequent among our sample (83% consulted either their GP or a mental health professional), but people living alone tend to use these health services more infrequently than these living with others. Though necessary, measures taken to protect victims, such as lockdown, may foster PTSD. Victims of terror attacks having been subjected to lockdown may have experienced powerlessness, fostering prolonged stress and fear. These victims may benefit from mental health support over the following months.

BACKGROUND: Bilateral subthalamic nucleus deep brain stimulation improves motor symptoms and treatment-related complications in patients with Parkinson's disease. However, some patients have trouble adjusting socially after successful neurosurgery, in part because of "unrealistic" expectations and psychiatric disorders. Preoperative psychological interventions focusing on these aspects could be beneficial for such patients. METHODS: We compared the outcomes of 2 psychosocial approaches-1 based on cognitive restructuration and 1 consisting of 2 interviews-with those of a control group without preoperative preparation. All patients underwent a psychometric evaluation 2 months before surgery (M-2) and again at 3 (M+3) and 6 months (M+6) after surgery. The psychometric evaluation focused on social adjustment using the social adjustment scale-self-report. The psychiatric profile of the patients was also assessed. RESULTS: Of 73 patients initially enrolled, 62 performed the initial inclusion visit (M-2) and the 2 postoperative visits (M+3, M+6). For these 62 patients (52% male), the overall mean age was 59 ± 6.13 years, and the mean disease duration was 9.44 ± 3.62 years. No specific differences were observed for social adjustment between the groups or visits (M-2, M+3, M+6); however, an interaction was found in the cognitive restructuration group at M+6 for the family dimension of the social adjustment scale-self-report. CONCLUSION: Our results suggest that even if no overall increase in the social adjustment score was observed, patients with Parkinson's disease eligible for neurosurgery should undergo preoperative psychosocial therapy to define their expectations and help them in their psychological restructuration. This type of therapy, complementary to psychoeducation, could represent an opportunity to prevent postoperative deception and social maladjustment.
