RESUMO

PURPOSE: To assess the level of stress and anxiety in healthcare workers in the departments of obstetrics and gynecology in France during and after the first Covid-19 lockdown. METHODS: Two web-based cross-sectional surveys using several validated questionnaires (the HAD scale, the PSS-10 questionnaire and the Short Form 12 Questionnaire [SF-12]) were proposed to all staff of obstetrics and gynecologic departments in 18 French university hospitals. RESULTS: A total of 1565 respondents answered the first questionnaire and 1109 completed the second survey. Respondents reported greater levels of stress and impaired mental quality of life during the lockdown, followed by a significant improvement after the end of lockdown (respectively p < .0001 and p = .01). Anxiety was significantly higher among the older participants during the lockdown (p = .008). The potential putative factors related to impaired mental health status were personal protective equipment (PPE) deficit (<.0001), the fear of contracting the virus from the workplace and transmitting to their families (<.0001) and concerns about information given by media and hospitals (<.0001). CONCLUSIONS: Understanding the heavy mental repercussions of the Covid-19 pandemic on healthcare workers could lead to the identification of high-risk in medical and non-medical staff and the implementation of targeted psychological monitoring program.

RESUMO

OBJECTIVES: To evaluate the diagnostic accuracy of the Impact Event Scale-Revisited assessed following ICU discharge to predict the emergence of post-traumatic stress disorder symptoms at 3 months. DESIGN: Prospective cohort study. SETTING: Three medical or surgical ICU of a French university hospital (Lyon, France). PATIENTS: Patients greater than or equal to 18 years old, leaving ICU after greater than or equal to 2 nights of stay, between September 2017 and April 2018. INTERVENTIONS: Patients completed the Impact Event Scale-Revisited and the Peritraumatic Dissociative Experiences Questionnaire within 8 days after ICU discharge and the Impact Event Scale-Revisited again at 3 months by phone. Patients having an Impact Event Scale-Revisited greater than or equal to 35 at 3 months were considered as having post-traumatic stress disorder symptoms. MEASUREMENTS AND MAIN RESULTS: Among the 208 patients screened, 174 were included and 145 reassessed by phone at 3 months. Among the patients included at baseline, 43% presented symptoms of acute stress. At 3 months, 13% had an Impact Event Scale-Revisited greater than or equal to 35 and 17% had a score between 12 and 34. Regarding the performance of the Impact Event Scale-Revisited performed within 8 days after the ICU discharge to predict post-traumatic stress disorder symptoms at 3 months, the area under the curve was 0.90 (95% CI, 0.80-0.99), and an Impact Event Scale-Revisited greater than or equal to 12 had a sensitivity of 90%, a specificity of 71%, a positive predictive value of 32%, and a negative predictive value of 98%. History of anxiety disorder odds ratio = 3.7 (95% CI, 1.24-11.05; p = 0.02) and Impact Event Scale-Revisited greater than or equal to 12 odds ratio = 16.57 (95% CI, 3.59-76.46; p < 0.001) were identified as risk factors for post-traumatic stress disorder symptoms. CONCLUSIONS: Impact Event Scale-Revisited assessed at ICU discharge has a good ability for the detection of patients at risk of developing post-traumatic stress disorder symptoms. Patients with history of anxiety disorder and those presenting acute stress symptoms at ICU discharge are more at risk to develop post-traumatic stress disorder symptoms.

RESUMO

Hemoglobin D-Punjab is a common hemoglobin variant in India but very rare in Morocco. Often, its presence has minimal or no clinical impact. Its heterozygous association with ß-thalassemia is exceptional. The purpose of the study is to describe the epidemiological, diagnostic and prophylactic aspects of hemoglobinosis D-Punjab from a family case study. MATERIAL AND METHODS: Case study of hemoglobinosis D-Punjab in a Moroccan family, diagnosed at the Laboratory of Biochemistry-Toxicology of the Mohammed V Military Teaching Hospital. The biological study was based on iron and hemolysis checkups, hemogram and study of hemoglobin (electrophoresis in alkaline and acid medium, high performance liquid chromatography). The index patient also benefited from sequencing by molecular biology. RESULTS: The index patient was heterozygous D-Punjab/ß0-thalassemia, confirmed by molecular biology. Two of her sisters had the same hemoglobin profile. At electrophoresis, all three had hemoglobin D-Punjab higher than 90%, hemoglobin A less than 1% and hemoglobin A2 higher than 6%. The results of the three hemograms showed similar abnormalities (pseudo-polycythemia, hypochromia, microcytosis, anisopoikilocytosis). Six other members of the family had a thalassemic trait and another three had heterozygous hemoglobinosis D-Punjab. CONCLUSION: Hemoglobin D-Punjab remains extremely rare in Morocco and very poorly documented in the literature. The number of reported cases is expected to raise due to increasing migration. Biologist advisory services require a precise diagnosis in order to give correct genetic counseling.

RESUMO

OBJECTIVES: The Beck Cognitive Insight Scale (BCIS) is composed of two subscales, self-reflectiveness and self-certainty, assessing reflectiveness and openness to feedback, and mental flexibility. Delusions have previously been associated with low cognitive insight. The aim of this study was to determine whether changes in BCIS scores predict changes in delusional beliefs. METHODS: The study is a secondary analysis of a previously published randomized controlled trial. All participants had a psychotic disorder diagnosis and received treatment as usual, with half of them also receiving the cognitive restructuring intervention 'Michael's game'. Participants were assessed at three different times: at baseline (T1), at 3 months (T2), and at 9 months (T3). Cognitive insight was measured with the BCIS, belief flexibility with the Maudsley assessment of delusions schedule (MADS), and psychotic symptoms with the Brief Psychiatric Rating Scale (BPRS). RESULTS: A total of 172 participants took part in the trial. After using generalized estimating equation (GEE) modelling, we observed (1) significant main effects of BCIS self-certainty and Time and (2) significant Time × BCIS self-certainty and Time × treatment group interaction effects on belief flexibility. Improvements in self-certainty (i.e., decrease in scores) were associated with more changes in conviction over time, more accommodation, improved ability in ignoring or rejecting a hypothetical contradiction and increased use of verification of facts. Medication and BPRS total scores were controlled for in the GEE analyses at their baseline values. CONCLUSIONS: Overall improvement in BCIS self-certainty scores over time predicted better treatment outcomes as assessed with MADS items. PRACTITIONER POINTS: Treatments for patients with psychosis should focus on improving cognitive insight as this seems to improve overall treatment outcomes and recovery. The Beck Cognitive Insight Scale can be used to measure changes during treatment and can predict treatment outcomes.

RESUMO

BACKGROUND: Most individuals with schizophrenia (SZ) have little to no insight regarding the presence of their illness. Psychoeducational programs are state-of-the-art interventions that consist in delivering stabilized patients with accurate knowledge about their illness and its treatment. Evidence suggests a significant relationship between levels of illness-related knowledge and insight in SZ patients. However, the effect of psychoeducation on these related outcomes needs to be explored further. METHODS: In this open label study involving 30 French-speaking patients with SZ, we propose to compare levels of knowledge and insight before and after the French P.A.C.T.® psychoeducation program to investigate how this approach affects both outcomes. Knowledge levels were measured with the self-questionnaire "What do I know?". Insight levels were measured using the Scale to Assess Unawareness of Mental Disorder (SUMD). Symptoms were assessed with the Positive And Negative Syndrome Scale (PANSS). RESULTS: A large significant improvement of knowledge was observed (p < 0.001; d = 0.77). By contrast, the analysis reported no significant effect of psychoeducation on insight (p = 0.86; d = 0.07). PANSS total scores were significantly decreased after treatment (p = 0.001; d = 0.66). CONCLUSIONS: Although the P.A.C.T.® program is a promising tool for improving illness-related knowledge in SZ patients, its use is not sufficient to significantly improve insight levels.

RESUMO

BACKGROUND: Obsessive-compulsive disorder (OCD) is a severe mental disorder with poor response to the available treatments. Neuroimaging studies have identified dysfunctions within the orbito-fronto-striato-pallido-thalamic network in patients with OCD. Here, we assessed the efficacy and safety of transcranial direct current stimulation (tDCS) applied with the cathode over the orbitofrontal cortex (OFC) and the anode over the right cerebellum to decrease OCD symptoms in patients with treatment-resistant OCD. METHODS: In a randomized sham-controlled double-blind study, 21 patients with OCD were assigned to receive ten 20-min sessions (two sessions per day) of either active (2 mA) or sham tDCS. The clinical symptoms were measured using the Yale-Brown Obsessive and Compulsive Scale (YBOCS). Acute effects on the symptoms were measured from baseline to immediately after the 10 tDCS sessions. Long-lasting effects were measured 1 and 3 months after the 10th tDCS session. RESULTS: Compared with the sham tDCS, active tDCS significantly decreased OCD symptoms immediately after the 10th tDCS session (F(1,19) = 5.26, p = 0.03). However, no significant differences were observed between the active and sham groups in terms of changes in YBOCS score or the number of responders one and 3 months after tDCS. CONCLUSION: Despite significant acute effects, tDCS with the cathode placed over the left OFC and the anode placed over the right cerebellum was not significantly effective in inducing a long-lasting reduction of symptoms in patients with treatment-resistant OCD.

RESUMO

Delusional beliefs and their behavioral consequences are predominant symptoms in patients with psychosis and play an important role in the treatment. Delusional beliefs are a multidimensional concept which can be divided into three components: distress, preoccupation and conviction of delusions. These can be measured using Peters delusions inventory (PDI-21). We question, whether changes in delusional beliefs over time during treatment measured with the PDI-21 can predict changes in belief flexibility measured with the Maudsley assessment of delusions schedule (MADS). We used a group of patients from a randomized controlled trial for a cognitive intervention for psychosis or psychotic symptoms. Aside standard treatment for psychosis, half of the patients took part in a group treatment "Michael's game". Patients were assessed at baseline (T1), at 3 months (T2), and at 9 months (T3). We measured delusional beliefs using PDI-21 and belief flexibility with the MADS. One hundred seventy-two patients were included in the analysis. We measured a main effect of PDI-21scores on belief flexibility measured with MADS. PDI-21 Conviction scores predicted outcomes for all measured MADS items. Increasing PDI Distress and Preoccupation scores were predictors for being more likely to dismiss beliefs and change conviction. Time itself was a predictor for changing conviction and being able to plan a behavioral experiment. Overall the changes in PDI scores predicted outcomes for belief flexibility measured with MADS items. The PDI-21 could be a simple and effective way to measure progress in treatment on delusional beliefs.

RESUMO

Despite the advances in psychopharmacology and established psychotherapeutic interventions, more than 40% of patients with obsessive-compulsive disorder (OCD) do not respond to conventional treatment approaches. Transcranial direct current stimulation (tDCS) has been recently proposed as a therapeutic tool to alleviate treatment-resistant symptoms in patients with OCD. The aim of this review was to provide a comprehensive overview of the current state of the art and future clinical applications of tDCS in patients with OCD. A literature search conducted on the PubMed database following PRISMA guidelines and completed by a manual search yielded 12 results: eight case reports, three open-label studies (with 5, 8, and 42 participants), and one randomized trial with two active conditions (12 patients). There was no sham-controlled study. A total of 77 patients received active tDCS with a large diversity of electrode montages mainly targeting the dorsolateral prefrontal cortex, the orbitofrontal cortex or the (pre-) supplementary motor area. Despite methodological limitations and the heterogeneity of stimulation parameters, tDCS appears to be a promising tool to decrease obsessive-compulsive symptoms as well as comorbid depression and anxiety in patients with treatment-resistant OCD. Further sham-controlled studies are needed to confirm these preliminary results.

RESUMO

Allogeneic hematopoietic stem cell transplantation can efficiently treat patients with severe hematological diseases. A human leukocyte antigen-compatible donor is required for performing transplantation. The occurrence of unexpected acute severe diseases in a donor can compromise the feasibility of allogeneic hematopoietic stem cell transplantation. However, when a severe health problem occurs in a donor while the recipient has already received a conditioning regimen, hematologists have to find the best solutions for the recipient, while the team in charge of the donor has to find the best medical solutions for the donor. We describe here the occurrence of psychiatric acute complications in an unrelated donor while the myeloablative conditioning regimen had already been given to the recipient. We report the successive decisions that were made in an emergency based upon the expertise of physicians specialized in hematology, apheresis, cell therapy, and psychiatry to preserve the donor's health and recipient's life.

RESUMO

Objectives to estimate the prevalence of persistent auditory hallucinations (AHs) in a group of schizophrenic patients, to evaluate their dimensions and to identify their clinical associated factors. Method This was a cross-sectional study carried-on 144 out-patients followed for schizophrenia, according DSM-IV-TR criteria. The assessment was consisted by the collect of epidemiological, clinical and therapeutic data and the use of the Hoffman's auditory hallucinations rating scale (AHRS), and the positive and negative symptoms scale (PANSS). Results The prevalence of persistent AHs (AHRS score ≥ 5) was 40.3%. The mean total score of the AHRS was 10.7±7.8 for all patients and 19.4±7.7 for patients with persistent AHs. The AHs dimensions with higher sub-scores were the number, the influence and the reality of the voices. The PANSS items most related to the AHRS total score were P3 "hallucinatory activity", G1 "somatic concerns", G4 "tension" and the G5 "mannerisms and posture disorders". The clinical associated factors with persistent AHs after multivariate analysis were the absence of tobacco consumption, the hallucinatory onset of disorders, the notion of previous hospitalization and the continuous course. Conclusion Our results support the multidimensionality of AHs and confirm the existence of inter individual differences in the characteristics of these hallucinations. Persistent AHs were associated with poor prognosis, requiring more effective therapeutic strategies.

RESUMO

OBJECTIVES: Schizophrenia is a group of severe psychiatric disorders with high heritability but only low odds ratios of risk genes. Despite progress in the identification of pathophysiological processes, valid biomarkers of the disease are still lacking. METHODS: This comprehensive review summarises recent efforts to identify genetic underpinnings, clinical and cognitive endophenotypes and symptom dimensions of schizophrenia and presents findings from neuroimaging studies with structural, functional and spectroscopy magnetic resonance imaging and positron emission tomography. The potential of findings to be biomarkers of schizophrenia is discussed. RESULTS: Recent findings have not resulted in clear biomarkers for schizophrenia. However, we identified several biomarkers that are potential candidates for future research. Among them, copy number variations and links between genetic polymorphisms derived from genome-wide analysis studies, clinical or cognitive phenotypes, multimodal neuroimaging findings including positron emission tomography and magnetic resonance imaging, and the application of multivariate pattern analyses are promising. CONCLUSIONS: Future studies should address the effects of treatment and stage of the disease more precisely and apply combinations of biomarker candidates. Although biomarkers for schizophrenia await validation, knowledge on candidate genomic and neuroimaging biomarkers is growing rapidly and research on this topic has the potential to identify psychiatric endophenotypes and in the future increase insight on individual treatment response in schizophrenia.

RESUMO

BACKGROUND: Obsessive-compulsive disorder (OCD) is a severe mental illness. OCD symptoms are often resistant to available treatments. Abnormalities within the orbitofronto-striato-pallido-thalamic circuitry, especially orbitofrontal cortex (OFC) hyperactivity and cerebellar hypoactivity have been observed in patients. Non-invasive brain stimulation studies have indicated that transcranial direct current stimulation (tDCS) may be a useful alternative to alleviate treatment-resistant symptoms in various neuropsychiatric conditions. METHODS: In an open-label pilot study, 8 patients with treatment-resistant OCD received 10 sessions (twice a day) of 2mA tDCS applied with the cathode over the left OFC and the anode over the right cerebellum. OCD (Y-BOCS and OCD-VAS) as well as depressive (MADRS) symptoms were measured 4 times: one time before tDCS and 3 times after (immediately after, 1 and 3months after the 10th tDCS session). RESULTS: We reported a significant 26.4% (±15.8) decrease of Y-BOCS score (p=0.002). The beneficial effect lasted during the 3month follow-up. No effect of tDCS was observed on depressive symptoms. At end point, 5 out of 8 patients had a decrease of ≥25%; and 3 out of 8 patients had a decrease of ≥35% in Y-BOCS score. tDCS was well tolerated. CONCLUSION: tDCS with the cathode placed over the left OFC combined with the anode placed over the right cerebellum is a suitable and safe approach to decrease OCD symptoms in patients with treatment-resistant OCD. Large scale randomized controlled studies are needed to confirm this promising result.

RESUMO

Auditory verbal hallucinations (AVH) in patients with schizophrenia are associated with abnormal hyperactivity in the left temporo-parietal junction (TPJ) and abnormal connectivity between frontal and temporal areas. Recent findings suggest that fronto-temporal transcranial Direct Current stimulation (tDCS) with the cathode placed over the left TPJ and the anode over the left prefrontal cortex can alleviate treatment-resistant AVH in patients with schizophrenia. However, brain correlates of the AVH reduction are unclear. Here, we investigated the effect of tDCS on the resting-state functional connectivity (rs-FC) of the left TPJ. Twenty-three patients with schizophrenia and treatment-resistant AVH were randomly allocated to receive 10 sessions of active (2 mA, 20 min) or sham tDCS (2 sessions/d for 5 d). We compared the rs-FC of the left TPJ between patients before and after they received active or sham tDCS. Relative to sham tDCS, active tDCS significantly reduced AVH as well as the negative symptoms. Active tDCS also reduced rs-FC of the left TPJ with the left anterior insula and the right inferior frontal gyrus and increased rs-FC of the left TPJ with the left angular gyrus, the left dorsolateral prefrontal cortex and the precuneus. The reduction of AVH severity was correlated with the reduction of the rs-FC between the left TPJ and the left anterior insula. These findings suggest that the reduction of AVH induced by tDCS is associated with a modulation of the rs-FC within an AVH-related brain network, including brain areas involved in inner speech production and monitoring.

RESUMO

Cognitive dysfunction is one of the hallmark deficits of schizophrenia. A wide range of studies illustrate how it is strongly interconnected to clinical presentation and daily life functioning [see Ref. (1, 2)]. Hence, cognition is an important treatment target in schizophrenia. To address the challenge of cognitive enhancement in schizophrenia, a large number of cognitive remediation programs have been developed and evaluated over the past several decades. First, an overview of these programs is presented highlighting their specificity to cognitive deficit in schizophrenia using an integrated method. In this case, cognitive training focuses on enhancing several elementary cognitive functions considered as a prerequisite to social skills or vocational training modules. These programs are based on the neurodevelopmental hypothesis of schizophrenia. However, moderate improvement for patients who benefit from these therapies has been observed as described in Wykes et al. review (3). Next, neuropsychological models of schizophrenia are then presented. They highlight the critical role of the internally generated intentions in appropriate willful actions. The cognitive control mechanism deals with this ability. Interestingly, available cognitive remediation programs have not been influenced by these models. Hence, we propose another alternative to set up a specific cognitive remediation program for schizophrenia patients by targeting the cognitive control mechanism. We describe the PrACTice program that is in the process of being validated.

RESUMO

OBJECTIVE: "Michael's game" (MG) is a card game targeting the ability to generate alternative hypotheses to explain a given experience. The main objective was to evaluate the effect of MG on delusional conviction as measured by the primary study outcome: the change in scores on the conviction subscale of the Peters delusions inventory (PDI-21). Other variables of interest were the change in scores on the distress and preoccupation subscales of the PDI-21, the brief psychiatric rating scale, the Beck cognitive insight scale, and belief flexibility assessed with the Maudsley assessment of delusions schedule (MADS). METHODS: We performed a parallel, assessor-blinded, randomized controlled superiority trial comparing treatment as usual plus participation in MG with treatment as usual plus being on a waiting list (TAU) in a sample of adult outpatients with psychotic disorders and persistent positive psychotic symptoms at inclusion. RESULTS: The 172 participants were randomized, with 86 included in each study arm. Assessments were performed at inclusion (T1: baseline), at 3 months (T2: post-treatment), and at 6 months after the second assessment (T3: follow-up). At T2, a positive treatment effect was observed on the primary outcome, the PDI-21 conviction subscale (p = 0.005). At T3, a sustained effect was observed for the conviction subscale (p = 0.002). Further effects were also observed at T3 on the PDI-21 distress (p = 0.002) and preoccupation subscales (p = 0.001), as well as on one of the MADS measures of belief flexibility ("anything against the belief") (p = 0.001). CONCLUSION: The study demonstrated some significant beneficial effect of MG.

RESUMO

Obsessive-compulsive disorder (OCD) is a disabling and frequent neuropsychiatric disorder. Forty percent to 60% of patients with OCD fail to respond to available treatments. Neuroimaging studies have highlighted an association between the severity of obsessive and compulsive symptoms and an increased activity of the left orbitofrontal cortex (OFC) in patients with OCD. Transcranial direct current stimulation (tDCS) is a powerful and easy-to-use tool to modulate brain activity. Cathodal tDCS (c-tDCS) is assumed to decrease cortical excitability in the targeted brain region. We hypothesized that c-tDCS applied over the left OFC alleviates symptoms in patients with treatment-resistant OCD. We report here the case of a patient who received 10 sessions (2 mA, 20 minutes) of c-tDCS. The tDCS sessions were delivered twice a day with a 2-hour interval, with the cathode (35 cm²) placed over the left OFC and the anode (100 cm²) placed over the contralateral occipital region. No adverse event was reported. One month after the completion of the tDCS sessions, we observed a 26% reduction in severity of obsessive and compulsive symptoms measured using the Yale-Brown Obsessive Compulsive Scale scores. These findings are consistent with a previous study reporting a similar reduction in obsessive and compulsive symptoms after a low-frequency repetitive transcranial magnetic stimulation was given to the left OFC. Our results indicate that c-tDCS applied over the left OFC may be a suitable and safe treatment in patients with treatment-resistant OCD.

RESUMO

Reduced N-acetyl-aspartate (NAA) levels have been reported in the prefrontal cortex (PFC) in patients with schizophrenia using proton magnetic resonance spectroscopy. However, it is unclear whether this NAA reduction predates the illness onset and is reported in subjects at-risk for developing schizophrenia (HRS). The aim of this study was to assess NAA levels in the PFC in HRS. We hypothesized that HRS display lower NAA levels than healthy controls in the PFC. Studies assessing levels of NAA/Creatine (NAA/Cr) in the PFC in HRS were extracted from literature. Meta-analysis tools were used to compute effect sizes of nine selected studies meeting our inclusion criteria (clinical and/or genetic HRS, groups of HRS, and healthy controls matched for age and gender, spectral acquisition in the PFC). We reported that HRS exhibited a significant lower NAA/Cr level (2.15 ± 0.29; n = 208) than healthy controls (2.21 ± 0.32; n = 234) in the PFC with a medium pooled effect size [Hedges's g = -0.42; 95% confidence interval: (-0.61; -0.23); p < 0.0001] corresponding to an average 5.7% of NAA/Cr decrease. Secondary analysis revealed that this reduction was observed in young HRS (<40 years old) who have not reached the peak age of risk for schizophrenia (-11%, g = -0.82, p < 0.00001) but not in old HRS (>40 years old) who have already passed the peak age (g = 0.11, p = 0.56), when they are compared with their matched healthy controls. Our findings suggest that the NAA/Cr reduction in the PFC reported in patients with schizophrenia is observable only in HRS who have not passed the peak age of risk for schizophrenia. NAA/Cr level in the PFC could therefore be considered as a biological vulnerability marker of schizophrenia.

RESUMO

To investigate the impact of various antipsychotic drugs on the 5-HT1A serotoninergic system, we performed a [F]4-(2-methoxyphenyl)-1-[2-(N-2-pirydynyl)-p-luorobenzamido]-ethyl-piperazine PET study in 19 schizophrenic patients treated with either aripiprazole, which has a partial agonist activity at 5-HT1A receptors, or second-generation antipsychotics (SGA) (olanzapine or risperidone), which do not demonstrate such property. We used a simplified reference tissue model to generate parametric images of [F]MPPF-binding potential (BPND). A significant reduction of [F]MPPF BPND was found in treated schizophrenic patients compared to age- and sex-matched healthy subjects. These modifications were mainly localized in the frontal and orbitofrontal cortex and may reflect either the pathophysiology of schizophrenia or medication effects. The schizophrenic patients treated with aripiprazole showed a reduction of global [F]MPPF BPND compared with healthy subjects and schizophrenic patients with SGA treatment. In addition, compared with matched controls, the reduction of regional [F]MPPF BPND was more marked in the schizophrenic patients treated with aripiprazole compared with those receiving SGA treatment, possibly reflecting the partial agonist of aripiprazole activity at 5-HT1A receptors.
