Relationship between transcranial magnetic stimulation markers of motor control and clinical recovery in obsessive compulsive disorder/Gilles de la Tourette syndrome: a proof of concept case study.

Background: Obsessive compulsive disorder (OCD) and Gilles de la Tourette syndrome (GTS) are neurodevelopmental disorders characterized by difficulties in controlling intrusive thoughts (obsessions) and undesired actions (tics), respectively. Both conditions have been associated with abnormal inhibition but a tangible deficit of inhibitory control abilities is controversial in GTS. Methods: Here, we examined a 25 years-old male patient with severe OCD symptoms and a mild form of GTS, where impairments in motor control were central. Transcranial magnetic stimulation (TMS) was applied over the primary motor cortex (M1) to elicit motor-evoked potentials (MEPs) during four experimental sessions, allowing us to assess the excitability of motor intracortical circuitry at rest as well as the degree of MEP suppression during action preparation, a phenomenon thought to regulate movement initiation. Results: When tested for the first time, the patient presented a decent level of MEP suppression during action preparation, but he exhibited a lack of intracortical inhibition at rest, as evidenced by reduced short-interval intracortical inhibition (SICI) and long-interval intracortical inhibition (LICI). Interestingly, the patient's symptomatology drastically improved over the course of the sessions (reduced obsessions and tics), coinciding with feedback given on his good motor control abilities. These changes were reflected in the TMS measurements, with a significant strengthening of intracortical inhibition (SICI and LICI more pronounced than previously) and a more selective tuning of MEPs during action preparation; MEPs became even more suppressed, or selectively facilitated depending on the behavioral condition in which they we probed. Conclusion: This study highlights the importance of better understanding motor inhibitory mechanisms in neurodevelopmental disorders and suggests a biofeedback approach as a potential novel treatment.

Physical Exercise to Redynamize Interoception in Substance use Disorders.

Physical exercise is considered a promising medication-free and cost-effective adjunct treatment for substance use disorders (SUD). Nevertheless, evidence regarding the effectiveness of these interventions is currently limited, thereby signaling the need to better understand the mechanisms underlying their impact on SUD, in order to reframe and optimize them. Here we advance that physical exercise could be re-conceptualized as an "interoception booster", namely as a way to help people with SUD to better decode and interpret bodily-related signals associated with transient states of homeostatic imbalances that usually trigger consumption. We first discuss how mismatches between current and desired bodily states influence the formation of reward-seeking states in SUD, in light of the insular cortex brain networks. Next, we detail effort perception during physical exercise and discuss how it can be used as a relevant framework for re-dynamizing interoception in SUD. We conclude by providing perspectives and methodological considerations for applying the proposed approach to mixed-design neurocognitive research on SUD.

Mental Health Nurses' Social Representations of People Who Experience Mental Illness: A Story of Paradoxes.

Public representations of people who experience mental illness (PEMI) have been well documented within the stigma literature. However, studies about mental health nurses' representations of PEMI are still scarce and characterized by contradictions. Using the theoretical concept of social representation instead of stigma, the current study aims to explore and understand mental health nurses' social representations of PEMI. Qualitative research was conducted based on 13 semi-structured interviews with nurses from two psychiatric units in general hospitals. Data were analyzed using interpretative phenomenological analysis. Results showed that nurses' social representations were characterized by paradoxes. They explicitly displayed positive social representations, while nuancing them from an implicit point of view. The nurses wanted to work toward a destigmatizing voice for PEMI while nuancing their assertions to sound honest and accurate, which led them to a state of cognitive dissonance.

Split Hospitalizations: a Model for Mood Disorders.

Depression is a major burden for society. While most mood disorders are treated on an outpatient basis, specific indications warrant hospitalization. Besides progresses in pharmacology, psychotherapy, or interventional procedures, we suggest that the hospital setting could also be used as a tool to address specific aspects of the mood disorder problem. Hospitalizations may present some iatrogenic effects and participate to the chronicization of some inpatients. In this paper, we propose a split hospitalization model for the treatment of mood disorders, where the stay in the hospital is split by a period of return to home, to test their ability to find own solutions to their mood difficulties. This split model could offset some of the negative effects inherent in long-term or repeated hospitalization, and chronicization. This model, where patients are treated as actors of their recovery supports the self-efficacy dimension by deconstructing a self-fulfilling prophecy based on the idea that the main function of the hospital is to serve as an asylum where the patient seeks protection against own self-destructive tendencies. This article outlines how the system was set up, described the expected therapeutic prospects, and presents a critical discussion of the main issues at stake.

Split Hospitalization as an Inpatient Care Proposal for Severe Alcohol-Use-Disorder: Considering Hospitalization as a Transition Towards Recovery.

BACKGROUND: The clinical dimensions of alcohol-use-disorder are complex and require sensitivity to these specificities. There are currently many inpatient and outpatient treatment facilities for severe alcohol-use-disorder patients (SAUD). We are also looking at the lack of access to care for this population. Recent research carried out in the cognitive and affective neurosciences and shed new light on the biological processes involved in addiction. SUBJECT AND METHOD: We wrote a perspective article describing the specific framework that we developed in our academic hospital. KEYWORDS: Hospital stay, hospital stay duration, benefits from hospitalization, alcoholism, alcohol use desorder. RESULTS: Through a review of the clinical characteristics that we observe in encounters with SAUD patients, we are going to describe a specific model of split hospitalisation. This is an open setting, with a fixed time frame and a multidisciplinary approach, designed to reduce the stigma attached to access and to support the development of the alcohol-dependent patient. CONCLUSION: In this paper, we describe the creation of an inpatient ward, that is complementary to the existing structures and take into account the cognitive and affective impairments of these patients.

Personal and Interpersonal Factors Moderate the Relation Between Human-Made Trauma and Hypertension: A Path Analysis Approach.

BACKGROUND: Although the link between trauma, posttraumatic stress disorder (PTSD), and hypertension is established, its underlying mechanisms remain underexplored. OBJECTIVE: This study tested a theoretical model exploring the moderating influence of psychological (emotion regulation) and interpersonal (social support) factors on the mediation between trauma and hypertension, through PTSD. METHODS: We measured these variables through self-reported questionnaire on 212 patients, recruited from internal medicine in a general hospital of Bukavu, a region affected by more than 25 years of armed conflicts. We first evaluated the PTSD mediation in the absence of moderators, before testing each moderator using moderated path analysis. RESULTS: Results showed that PTSD partially mediates the relationship between human-made trauma and hypertension, whereas social support and maladaptive emotion regulation moderate the relationship between human-made trauma and PTSD. CONCLUSIONS: The relationship between human-made trauma, PTSD, and hypertension might be modulated by psychological and interpersonal factors, which paves the way for new interventions targeting emotion regulation and social support to reduce PTSD and hypertension in populations exposed to human-made violence.

Links between psychopathological symptoms and cortical thickness in men with severe alcohol use disorder: A Magnetic Resonance Imaging study.

BACKGROUND: Anxiety and depression are psychopathological states frequently co-occurring with severe alcohol use disorder (SAUD). These symptoms generally disappear with abstinence but may persist in some patients, increasing the relapse risk. METHODS: The cerebral cortex thickness of 94 male patients with SAUD was correlated with symptoms of depression and anxiety, both measured at the end (2-3 weeks) of the detoxification treatment. Cortical measures were obtained using surface-based morphometry implemented with Freesurfer. RESULTS: Depressive symptoms were associated with reduced cortical thickness in the superior temporal gyrus of the right hemisphere. Anxiety level was correlated with lower cortical thickness in the rostral middle frontal region, inferior temporal region, and supramarginal, postcentral, superior temporal, and transverse temporal regions of the left hemisphere, as well as with a large cluster in the middle temporal region of the right hemisphere. CONCLUSIONS: At the end of the detoxification stage, the intensity of depressive and anxiety symptoms is inversely associated with the cortical thickness of regions involved in emotions-related processes, and the persistence of the symptoms could be explained by these brain deficits.

Prescribing and deprescribing trends in schizophrenia: An overview of inpatients in Belgium and in the Canadian province of Québec.

Although switching to antipsychotic monotherapy improves patient outcomes in schizophrenia, antipsychotic deprescribing is rarely performed, and its use varies between countries, as do psychotropic prescribing patterns. This study aimed to determine factors associated with antipsychotic deprescribing at discharge after a psychiatric hospitalization and to compare psychotropic prescribing patterns between Belgium and Québec, Canada. Data on adult inpatients with schizophrenia were collected retrospectively in seven hospitals. At discharge, the number of antipsychotics had decreased in 22.2% of the 63 Canadian patients and 9.9% of the 516 Belgian patients. A number of factors increased the likelihood of antipsychotic deprescribing: a hospitalization in the Canadian hospital (aOR = 4.13, 95% CI 1.48-11.5), living in a residential facility (aOR = 2.51, 95% CI 1.05-4.39), ≥2 previous antipsychotic trials (aOR = 15.38, 95% CI 3.62-65.36), having an antipsychotic side effect (aOR = 1.86, 95% CI 1.01-3.44) and being in a general hospital (aOR = 2.28, 95% CI 1.09-4.75). Patients on a long-acting injectable antipsychotic (aOR = 0.51, 95% CI 0.26-0.98), with prior clozapine use (aOR = 0.36, 95% CI 0.13-0.95), greater antipsychotic exposure (aOR = 0.35, 95% CI 0.2-0.61) and more hypno-sedatives (aOR = 0.65, 95% CI 0.43-0.98), were less likely to be deprescribed. Specific deprescribing interventions could target patients who are less likely to be deprescribed.

Impact of a Caffeine Restriction Policy on Inpatients With Schizophrenia: A Pre-Post Comparison Using Electronic Health Records.

BACKGROUND/PURPOSE: Caffeine is the most commonly used psychostimulant worldwide. Although its large intake is suspected to worsen psychotic symptoms because of increasing dopamine neurotransmission, schizophrenic patients are heavier caffeine consumers than the general population. This study aims to assess the impact of a caffeine restriction policy in a psychiatric hospital on patient psychopathology, hospitalization characteristics, and psychotropic prescribing patterns. METHODS: It is a retrospective cross-sectional study based on electronic health records of a psychiatric hospital in the French-speaking area of Belgium. Two different periods were compared, the first (n = 142), in 2017, when caffeine was available in the institution and the second (n = 119), between November 2018 and November 2019 after the restriction of access to caffeine was implemented. Adult inpatients with schizophrenia or schizoaffective disorder admitted for an acute hospitalization were included. Antipsychotic exposure, benzodiazepine daily dose, Global Assessment of Functioning scores, length of hospital stay, and some other factors were tested for their potential association with the decaffeinated period. RESULTS: After adjusting for potential confounders, reduced caffeine availability inside the hospital was significantly associated with higher Global Assessment of Functioning scores at discharge (adjusted odds ratio [aOR] = 2.86, 95% confidence interval [CI] = 1.77-4.62) and shorter hospital stays (aOR = 0.68, 95% CI = 0.47-0.99) but was not associated with change in antipsychotic exposure at discharge (aOR = 1.04, 95% CI = 0.64-1.7) or benzodiazepine daily dose (aOR = 0.89, 95% CI = 0.61-1.29). CONCLUSIONS: Limiting access to caffeine in psychiatric hospitals is a simple and inexpensive intervention that should be promoted, especially for patients with schizophrenia.

Molecular Imaging Studies of Alcohol Use Disorder.

Alcohol use disorder (AUD) is a serious public health problem in many countries, bringing a gamut of health risks and impairments to individuals and a great burden to society. Despite the prevalence of a disease model of AUD, the current pharmacopeia does not present reliable treatments for AUD; approved treatments are confined to a narrow spectrum of medications engaging inhibitory γ-aminobutyric acid (GABA) neurotransmission and possibly excitatory N-methyl-D-aspartate (NMDA) receptors, and opioid receptor antagonists. Molecular imaging with positron emission tomography (PET) and single-photon emission computed tomography (SPECT) can open a window into the living brain and has provided diverse insights into the pathology of AUD. In this narrative review, we summarize the state of molecular imaging findings on the pharmacological action of ethanol and the neuropathological changes associated with AUD. Laboratory and preclinical imaging results highlight the interactions between ethanol and GABA A-type receptors (GABAAR), but the interpretation of such results is complicated by subtype specificity. An abundance of studies with the glucose metabolism tracer fluorodeoxyglucose (FDG) concur in showing cerebral hypometabolism after ethanol challenge, but there is relatively little data on long-term changes in AUD. Alcohol toxicity evokes neuroinflammation, which can be tracked using PET with ligands for the microglial marker translocator protein (TSPO). Several PET studies show reversible increases in TSPO binding in AUD individuals, and preclinical results suggest that opioid-antagonists can rescue from these inflammatory responses. There are numerous PET/SPECT studies showing changes in dopaminergic markers, generally consistent with an impairment in dopamine synthesis and release among AUD patients, as seen in a number of other addictions; this may reflect the composite of an underlying deficiency in reward mechanisms that predisposes to AUD, in conjunction with acquired alterations in dopamine signaling. There is little evidence for altered serotonin markers in AUD, but studies with opioid receptor ligands suggest a specific up-regulation of the µ-opioid receptor subtype. Considerable heterogeneity in drinking patterns, gender differences, and the variable contributions of genetics and pre-existing vulnerability traits present great challenges for charting the landscape of molecular imaging in AUD.

An eye-tracking study of biased attentional processing of emotional faces in severe alcohol use disorder.

BACKGROUND: Social cognition impairments in severe alcohol use disorder (SAUD) are increasingly established. However, fundamental aspects of social cognition, and notably the attentional processing of socio-affective information, remain unexplored, limiting our understanding of underlying mechanisms. Here, we determined whether patients with SAUD show attentional biases to specific socio-affective cues, namely emotional faces. METHOD: In a modified dot-probe paradigm, 30 patients with SAUD and 30 demographically matched healthy controls (HC) were presented with pairs of neutral-emotional (angry, disgusted, happy, sad) faces while having their eye movements recorded. Indices of early/automatic (first fixations, latency to first fixations) and later/controlled (number of fixations, dwell-time) processes were computed. RESULTS: Patients with SAUD did not differ from HC in their attention to angry/disgusted/sad vs. neutral faces. However, patients with SAUD fixated/dwelled less on happy vs. neutral faces in the first block of stimuli than HC, who presented an attentional bias to happy faces. LIMITATIONS: Sample-size was determined to detect medium-to-large effects and subtler ones may have been missed. Further, our cross-sectional design provides no explanation as to whether the evidenced biases precede or are a consequence of SAUD. CONCLUSIONS: These results extend the social cognition literature in SAUD to the attentional domain, by evidencing the absence of a controlled attentional bias toward positive social cues in SAUD. This may reflect reduced sensitivity to social reward and could contribute to higher order social cognition difficulties and social dysfunction.

Exploring the links between gut microbiota and excitatory and inhibitory brain processes in alcohol use disorder: A TMS study.

While the impact of the gut microbiota on brain and behavior is increasingly recognized, human studies examining this question are still scarce. The primary objective of the current study was to explore the potential relationships between the gut microbiota composition, motor cortical excitability at rest and during inhibitory control, as well as behavioral inhibition, in healthy volunteers and in patients suffering from alcohol use disorder. Motor cortical excitability was examined using a range of transcranial magnetic stimulation (TMS) measures probed at rest, including the recruitment curve, short and long intracortical inhibition, and intracortical facilitation within the primary motor cortex. Moreover, TMS was applied during a choice reaction time task to assess changes in motor excitability associated with inhibitory control. Finally, behavioral inhibition was investigated using a neuropsychological task (anti-saccade). Overall, our results highlight several interesting correlations between microbial composition and brain measures. Hence, higher bacterial diversity, as well as higher relative abundances of UGC-002 and Christensenellaceae R-7 group were correlated with stronger changes in motor excitability associated with inhibitory control. Also, higher abundance of Anaerostipes was associated with higher level of corticospinal excitability. Finally, relative abundances of Bifidobacterium and Faecalibacterium were positively related to performance in the neuropsychological task, suggesting that they might have a positive impact on behavioral inhibition. Although correlation is not causation, the present study suggests that excitatory and inhibitory brain processes might be related to gut microbiota composition. This article is part of the Special Issue on 'Microbiome & the Brain: Mechanisms & Maladies'.

Drug adherence and psychological factors in patients with apparently treatment-resistant hypertension: Yes but which ones?

The aim of the study was to assess drug adherence, as well as association of psychological factors with both drug adherence and severity of hypertension in two subtypes of patients with apparently treatment-resistant hypertension (ATRH): younger patients with uncomplicated hypertension (YURHTN) versus patients ≥60-year-old and/or with a history of cardio- or cerebrovascular complication (OCRHTN). Drug adherence was assessed in urine by targeted Liquid Chromatography-Mass Spectrometry. The severity of hypertension was assessed by 24-h ambulatory blood pressure adjusted for the number of antihypertensive drugs and for drug adherence. Psychological profile was assessed using five validated questionnaires. The proportion of totally non-adherent patients was three times higher (24.1 vs. 7.1%, P = 0.026) in the YURHTN (n = 54) than in OCRHTN subgroup (n = 43). Independent predictors of drug adherence in YURHTN were ability to use adaptive strategies, male sex and family history of hypertension, accounting for 39% of variability in drug adherence. In the same subgroup, independent predictors of severity of hypertension were somatization and lower recourse to planification, accounting for 40% of variability in the severity of hypertension. In contrast, in the OCRHTN subgroup, independent predictors of drug adherence and severity of hypertension were limited to the number of yearly admissions to the emergency room and the total number of prescribed drugs. In conclusion, poor drug adherence and altered psychological profiles appear to play a major role in younger patients with ATRH devoid of cardiovascular complication. This subgroup should be prioritized for chemical detection of drug adherence and psychological evaluation.

Antipsychotic polypharmacy and clozapine prescribing patterns: evolution and correlates before and after a psychiatric hospitalisation.

Background: Antipsychotic polypharmacy (APP) prescribing and clozapine underuse are considered inappropriate prescribing in schizophrenia. Psychiatric hospitalisations may be suitable occasions to re-evaluate patient pharmacotherapy and to switch to monotherapy. Objectives: To explore the evolution of APP and other psychotropic prescribing patterns during psychiatric hospitalisations, to detect characteristics associated with APP on admission and at discharge, and to examine clozapine prescribing patterns. Design: We performed a retrospective observational study based on electronic health records. Methods: Data on adult inpatients diagnosed with schizophrenia spectrum disorders were collected retrospectively from 6 Belgian hospitals in 2020-2021. Results: Of the 516 patients included, APP prescribing increased significantly from 47.9% on hospital admission to 59.1% at discharge. On admission and at discharge, APP was associated with prior clozapine use (ORadmission = 2.53, CI = 1.1-5.84, ORdischarge = 11.01, CI = 4.45-27.28), treatment with a first-generation antipsychotic (ORadmission = 26.79, CI = 13.08-54.86, ORdischarge = 25.2, CI = 12.2-52.04), increased antipsychotic exposure (ORadmission = 8.93, CI = 5.13-15.56, ORdischarge = 19.89, CI = 10-39.54), and a greater number of hypno-sedatives (ORadmission = 1.88, CI = 1.23-2.88, ORdischarge = 4.18, CI = 2.53-6.91). APP was negatively associated with involuntary admission (ORadmission = 0.31, CI = 0.14-0.7, ORdischarge = 0.3, CI = 0.13-0.68). When using an alternative definition of monotherapy (i.e. including patients with an add-on low-dose antipsychotic for sleep disorders), alcohol use disorder (ORadmission = 0.26, CI = 0.13-0.54) and higher age (ORdischarge = 0.53, CI = 0.29-0.95) were negatively associated with APP, and living in a residential facility (ORdischarge = 2.39 CI = 1.21-4.71) and a higher daily dosage of benzodiazepines during the stay (ORdischarge = 1.32 CI = 1.03-1.69) increased the odds of being discharged on APP. On admission, 9.3% of patients were being treated with clozapine. Although 28.1% of patients were eligible for clozapine treatment, only 11% of patients were discharged with a clozapine prescription. For 7 of the 10 patients with a new clozapine prescription, it was directly prescribed in combination with another antipsychotic, without a prior trial of clozapine monotherapy. Conclusion: Suboptimal prescriptions of antipsychotics in patients with schizophrenia persist after psychiatric hospitalisations and are associated with identifiable characteristics.

Psychopathological states among Congolese health workers during the first wave of COVID-19 pandemic: links with emotion regulation and social support.

Background: The COVID-19 pandemic is an unprecedented stressor for frontline healthcare workers, notably increasing acute stress disorder and depression rates. Emotion regulation and social support could be major protective factors against such psychopathological states, but their role has not been explored outside Western contexts. Objective: To assess the association between emotion regulation, social support, acute stress disorder, and depression among healthcare workers directly confronted with the first wave of COVID-19 pandemic in the eastern Democratic Republic of the Congo. Method: A cross-sectional study assessed acute stress disorder, depression, adaptive (i.e. acceptance, positive refocusing, …) and maladaptive (i.e. self-blame, rumination, catastrophizing, …) emotion regulation strategies, social support (instrumental, emotional, and informational levels), as well as self-reported situations and feelings related to COVID-19, in a population of 252 frontline healthcare workers (121 women; 131 men; mean age: 39 ± 11 years old) at the Referral General Hospital of Bukavu. We also explored the relations between these variables through bivariate and multivariate logistic regression. Results: Forty percent of participants presented symptoms of depression, and 16% presented acute stress disorder. In bivariate logistic regression, these psychiatric outcomes were associated with the availability of a COVID-19 protection kit [OR = 0.24 (0.12-0.98)], hostility toward health workers [OR = 3.21 (1.23-4.21)], putting into perspective [OR = 0.91 (0.43-0.98)], self-blame [OR = 1.44 (1.11-2.39)], catastrophizing [OR = 1.85 (1.01-4.28)], blaming others [OR = 1.77 (1.04-3.32)], emotional support [OR = 0.83 (0.49-0.98)], instrumental support [OR = 0.74 (0.28-0.94)], and informational support [OR = 0.73 (0.43-0.98)]. In multivariate logistic regression, hostility [OR = 2.21 (1.54-3.78)], self-blame [OR = 1.57 (1.02-2.11)], rumination [OR = 1.49 (1.11-3.13)] and emotional support [OR = 0.94 (0.65-0.98)] remained significantly associated with psychiatric outcomes. Conclusion: Depression and acute stress disorder were highly prevalent among Congolese healthcare workers during the first wave of the COVID-19 health pandemic. Hostility, self-blame, rumination, and social support were associated with depression and/or acute stress disorder and should be targeted by interventions aiming to support health workers' wellbeing. HIGHLIGHTS: Frontline health workers presented high prevalence of acute stress disorder (16%) and depression (40%) during the first wave of COVID-19 pandemic in the Eastern Democratic Republic of the Congo, as they were working in hostile environment without enough protection kits.Acute stress disorder and depression were negatively associated with adaptive emotion regulation and social support; and positively with maladaptive emotion regulation.Intervention aiming to support health workers in pandemics should target emotion regulation and social support.

Antecedentes: La pandemia de COVID-19 es un factor estresante sin precedentes para los trabajadores de atención médica de primera línea, que aumenta notablemente las tasas de trastorno por estrés agudo y depresión. La regulación de las emociones y el apoyo social podrían ser factores protectores importantes contra tales estados psicopatológicos, pero su papel no ha sido explorado fuera de los contextos occidentales.Objetivo: Evaluar la asociación entre la regulación de las emociones, el apoyo social, el trastorno de estrés agudo y la depresión entre los trabajadores de la salud que confrontaron directamente la primera ola de la pandemia de COVID-19 en el este de la República Democrática del Congo.Método: Un estudio transversal evaluó el trastorno de estrés agudo, la depresión, estrategias de regulación emocional adaptativas (es decir, aceptación, refocalización positiva, …) y desadaptativas (es decir, autoculpabilización, rumiación, catastrofización, …), apoyo social (niveles instrumental, emocional, e informacional), así como situaciones y sentimientos autoinformados relacionados con el COVID-19, en una población de 252 trabajadores de salud de primera línea (121 mujeres; 131 hombres; edad media: 39 ± 11 años) en el Hospital General de Referencia de Bukavu. También exploramos las relaciones entre estas variables mediante regresión logística bivariada y multivariada.Resultados: Cuarenta por ciento de los participantes presentó síntomas de depresión y el dieciséis por ciento presentó trastorno de estrés agudo. En regresión logística bivariada, estos resultados psiquiátricos se asociaron con la disponibilidad de un kit de protección COVID-19 [OR = 0.24 (0.12­0.98)], hostilidad hacia los trabajadores de la salud [OR = 3.21 (1.23­4.21)], postura en perspectiva [ OR = 0.91 (0.43­0.98)], autoculpabilización [OR = 1.44 (1.11­2.39)], catastrofización [OR = 1.85 (1.01­4.28)], heteroculpabilización [OR = 1.77 (1.04­3.32)], apoyo emocional [OR = 0.83 (0.49­0.98)], apoyo instrumental [OR = 0.74 (0.28­0.94)] y apoyo informativo [OR = 0.73 (0.43­0.98)]. En la regresión logística multivariada, hostilidad [OR = 2.21 (1.54­3.78)], autoculpabilización [OR = 1.57 (1.02­2.11)], rumiación [OR = 1.49 (1.11­3.13)] y apoyo emocional [OR = 0.94 (0.65­0.98)] permanecieron significativamente asociados con los resultados psiquiátricos.Conclusión: La depresión y el trastorno de estrés agudo fueron muy frecuentes entre los trabajadores de la salud congoleños durante la primera ola de la pandemia sanitaria de COVID-19. La hostilidad, la autoculpabilización, la rumiación y el apoyo social se asociaron con depresión y/o trastorno de estrés agudo y deberían ser el objetivo de las intervenciones destinadas a apoyar el bienestar de los trabajadores de la salud.

Predictors of acute stress disorder in victims of violence in Eastern Democratic Republic of the Congo.

Background: The Democratic Republic of the Congo underwent more than 25 years of war resulting in millions of deaths and in survivants struggling with trauma related disorders. The factors contributing to acute stress disorder following a traumatic event remain little understood. Emotion regulation might play a role in the development of acute stress disorder among victims of war-related violence. Objectives: We assessed the association between acute stress disorder expression and cognitive strategies of emotion regulation among injured victims of violence in the Eastern Democratic Republic of the Congo. Methods: This cross-sectional study included 120 patients (77% males, mean age 30 ± 11 years) with traumatic wounds admitted at the Bukavu General Hospital. We assessed acute stress disorder through the Stanford Acute Reaction Stress Questionnaire and emotion regulation strategies through the Cognitive emotional regulation questionnaire. Results: Using Pearson Chi2 and Student t-test we found that compared with patients without acute stress disorder (N = 56), patients with acute stress disorder (N = 64) were more likely to be victims of armed robbery (p = .02), of a bullet (p = .04), of having wounds with fracture (p = .03) or neurological damage (p = .05). In multivariate logistic regression, wounds with neurological damage [OR = 2.23 (1.03-6.05)] and maladaptive emotion regulation, namely self-blame [OR = 1.71 (1.01-3.21)] and rumination [OR = 1.97 (1.04-4.13)], were significant predictors of acute stress disorder. Conclusion: Acute stress disorder was prevalent in the aftermath of violence induced injuries and might be associated with emotion regulation strategies such as self-blame and rumination. HIGHLIGHTS Acute stress disorder is strongly associated with maladaptive emotion regulation strategies such as self-blame and rumination.Interventions targeting emotion regulation may reduce acute stress reactions in the aftermath of violence induced injuries.

Antecedentes: La República Democrática del Congo atravesó más de 25 años de guerra, resultando en millones de muertos y en los sobrevivientes experimentando trastornos relacionados con trauma. Los factores que contribuyen a desarrollar un trastorno de estrés agudo después de un evento traumático permanecen poco comprendidos. La regulación emocional podría jugar un rol en el desarrollo del trastorno de estrés agudo entre las víctimas de violencia relacionada con la guerra.Objetivos: Evaluamos la asociación entre la expresión del trastorno de estrés agudo y estrategias cognitivas de regulación emocional entre las víctimas de violencia lesionadas en el este de la República Democrática del Congo.Métodos: Este estudio transversal incluyó a 120 pacientes (77% varones, edad media 30 ± 11 años) con heridas traumáticas ingresados al Hospital General de Bukavu. Evaluamos el trastorno de estrés agudo a través del Cuestionario de Reacción Aguda al Estrés de Stanford y estrategias de regulación emocional a través del Cuestionario de Regulación Emocional Cognitiva.Resultados: Usando el Chi2 de Pearson y la prueba de t de Student encontramos que en comparación con pacientes sin trastorno de estrés agudo (N=56), los pacientes con trastorno de estrés agudo (N=64) fueron más probablemente víctimas de robo a mano armada (p=.02), de bala (p=.04), de tener heridas con fractura (p=.03) o daño neurológico [OR= 2.23 (1.03-6.05)] y regulación emocional desadaptativa, esto es, culpa [OR= 1.71 (1.01-3.21)] y rumiación [OR= 1.97 (1.04-4.13)], fueron predictores significativos de trastorno de estrés agudo.Conclusión: El trastorno de estrés agudo fue prevalente después de lesiones provocadas por violencia y podría asociarse con estrategias de regulación emocional como la culpa y la rumiación.

Feasibility of Online High-Intensity Interval Training (HIIT) on Psychological Symptoms in Students in Lockdown During the COVID-19 Pandemic: A Randomized Controlled Trial.

Objective: We aimed to evaluate the feasibility of an online High-Intensity Interval Training (HIIT) program on clinical psychological symptoms in higher education students in the context of the COVID-19 pandemic lockdown. Materials and Methods: During the lockdown, 30 students aged 18-25 years, who had been screened previously with a cut-off score ≥5 in the Generalized Anxiety Disorder-7 (GAD-7) questionnaire, were randomly assigned to either the 4-week HIIT program with three sessions per week conducted through online videos, or a no-intervention control group. The primary outcome was the feasibility assessment. The secondary outcome was a psychological self-report with the 21-items Depression, Anxiety, and Stress Scale (DASS-21). Assessment and intervention were performed in compliance with social distancing rules. Results: Two participants in the HIIT were lost to follow-up, leaving 13 participants vs. 15 in the control group. We observed high adherence (87%) and complete safety for mental and physical status with the HIIT intervention delivered by online videos. The Mann-Whitney test demonstrated a significant (group × time, P-Value = 0.046) reduction of clinical stress symptoms and a trend (group × time, P-Value = 0.08) toward reduction of clinical depression symptoms, both favoring the HIIT group. No significant (group × time, P-Value = 0.118) interaction was found for anxiety symptoms. Conclusion: The online HIIT program was found to be feasible and safe in a clinical sample of young adults, who were experiencing social and physical restrictions due to COVID-19. HIIT reduced stress and depressive symptoms and thus these preliminary results show promise for broader application among higher education students during the present lockdown necessitated by the global COVID-19 health crisis.

Psychological determinants of drug adherence and severity of hypertension in patients with apparently treatment-resistant vs. controlled hypertension.

PURPOSE: In a pilot study including 35 patients with apparently treatment-resistant hypertension (ATRH), we documented associations between psychological profile, drug adherence and severity of hypertension. The current study aims to confirm and expand our findings in a larger and more representative sample of patients with ATRH, using controlled hypertensive patients as the comparator. MATERIALS AND METHODS: Patients with ATRH were enrolled in hypertension centres from Brussels and Torino. The psychological profile was assessed using five validated questionnaires. Drug adherence was assessed by high-performance liquid chromatography-tandem mass spectrometry analysis of urine samples, and drug resistance by 24-hour ambulatory blood pressure was adjusted for drug adherence. RESULTS: The study sample totalised 144 patients, including 81 ATRH and 63 controlled hypertensive patients. The mean adherence level was significantly lower in the "resistant" group (78.9% versus 92.7% in controlled patients, p-value = .022). In patients with ATRH, independent predictors of poor drug adherence were somatisation, smoking and low acceptance level of difficult situations, accounting for 41% of the variability in drug adherence. Independent predictors of severity of hypertension were somatisation, smoking, more frequent admissions to the emergency department and low acceptation, accounting for 63% of the variability in the severity of hypertension. In contrast, in patients with controlled hypertension, the single predictors of either drug adherence or severity of hypertension were the number of years of hypertension and, for the severity of hypertension, alcohol consumption, accounting for only 15-20% of the variability. CONCLUSION: Psychological factors, mostly related to somatisation and expression of emotions are strong, independent predictors of both drug adherence and severity of hypertension in ATRH but not in controlled hypertensive patients.

This study included 144 patients with Apparently-Treatment Resistant (ATRH) or controlled Hypertension: Patients with ATRH were more often poorly adherent to antihypertensive treatment than controlled hypertensive patients.In patients with ARTH but not patients with controlled hypertension, psychological traits were strong, independent predictors of drug adherence and severity of hypertension, over and above demographic and health-related factors.In patients with ATRH, the tendency to somatize, i.e. expressing somatic symptoms that cannot be adequately explained by organic findings was the most potent predictor of both poor drug adherence and severity of hypertension.These patients also often presented alterations in the expression of emotions. It may be hypothesised that subjects who have difficulties identifying and expressing emotions with words will express them by physical complaints, and, in the mid-long term, might develop overt diseases.In addition to more classical lifestyle and drug management and irrespective of their drug adherence level, patients with ATRH may benefit in priority from psychological evaluation and interventions. However, this needs to be studied in an interventional trial in the future.
