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.

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.

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.

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.

Psychological distress among hospital caregivers during and after the first wave of COVID-19: Individual factors involved in the severity of symptoms expression.

Coronavirus disease 2019 has spread rapidly over the globe and has put an unprecedent psychological pressure on health care workers (HCWs). The present study aimed at quantifying the psychological consequences of the COVID-19 pandemic on HCWs during and after the first wave and identify sociodemographic, situational, and psychological risk/protective factors for symptoms severity. An online survey was sent by e-mail to all nurses and physicians employed by a teaching hospital in Brussels, Belgium. 542 (20,62%) completed the survey. 47%, 55%, 32% and 52% of participants reported posttraumatic stress, anxiety, depression and insomnia symptoms, respectively, during the peak. Two to three months later, posttraumatic symptoms emerged de novo in 54% of HCWs. It persisted in 89% of those presenting severe symptoms initially. Neuroticism was the strongest predictor of posttraumatic stress, anxiety, and insomnia. Work overload was the strongest predictor of depression and second predictor of posttraumatic stress, anxiety, and insomnia. Other significant predictors included being a nurse, the number of past traumatic experiences, avoidant coping style, and expressive suppression of emotions.

Association between post-traumatic stress disorder and hypertension in Congolese exposed to violence: a case-control study.

BACKGROUND: Numerous risk factors have been involved in the pathogenesis of hypertension. The contribution of psychological factors, including post-traumatic stress disorder, remains largely underexplored, despite their potential role in hypertension. OBJECTIVES: We compared the prevalence of trauma, post-traumatic stress and other psychological disorders between hypertensive and normotensive patients from Bukavu (Democratic Republic of Congo), a 25-year war-exposed city. METHODS AND MEASURES: In this case-control study, we assessed past traumatic events with the Stressful-Events-Scale, post-traumatic stress disorder through the post-traumatic diagnostic scale, depression and alcohol use disorder through the MINI-International-Neuropsychiatric-Interview, and emotion regulation through the Emotion-Regulation-Questionnaire in 106 hypertensive and 106 normotensive patients, enrolled at the Bukavu General Hospital. RESULTS: Compared with normotensive controls (73% women, age: 43 ±â€Š14 years, BP: 121 ±â€Š10/75 ±â€Š8 mmHg), hypertensive patients (57% women, age: 42 ±â€Š13 years, BP: 141 ±â€Š12/82 ±â€Š7 mmHg, on a median of two antihypertensive drugs) were exposed to more man-made traumas (61 vs. 13%, P < 0.001), used more expressive suppression (P = 0.05) and less cognitive reappraisal (P = 0.02) as emotional regulation strategies. They developed more frequent post-traumatic stress disorder (36 vs. 7%, P < 0.001) and major depressive disorder (37 vs. 13%, P = 0.001), often in association with alcohol use disorder (23 vs. 4%, P < 0.001). In multivariate logistic regression, post-traumatic stress disorder [OR = 3.52 (1.23-6.54)], man-made trauma [OR = 2.24 (1.15-4.12)], family history of hypertension [OR = 2.24 (1.06-4.44)], fasting blood glucose [OR = 1.85 (1.07-3.08)], BMI [OR = 1.28 (1.12-2.92)], expressive suppression [OR = 1.23 (1.11-2.23)] and cognitive reappraisal [OR = 0.76 (0.63-0.98)] were independent predictors of hypertension. CONCLUSION: In Congolese populations exposed to war, man-made trauma exposure and post-traumatic stress disorder appear to be more tightly related to hypertension than classical hypertension risk factors.

Case study: Developing a strategy combining human and empirical interventions to support the resilience of healthcare workers exposed to a pandemic in an academic hospital.

The COVID-19 pandemic has put healthcare workers under important psychological pressure. Concerns have been raised regarding the mental health and psychological status of healthcare workers and have underlined the need for institutions to develop long-term interventions to support their resilience. The current case study presents the way a large university hospital in Brussels, Belgium, has evolved to deal with this health crisis and support its workers. Initiatives were multiple and complementary, as it was decided to combine different forms of clinical interventions that were developed by psychologists, psychiatrists, and human resources, to an empirical approach including a large survey that permitted to reach a much larger audience (the results of the study have been published previously). We describe the initially proposed measures of psychological support, including the creation of a telephone hotline, the presence of psychologists among teams of dedicated COVID-19 units, discussion groups, and individualized follow-ups, and their consequences on healthcare workers. Second, we address how these initial measures of support were modified to tailor in the best way possible the needs of healthcare workers, using a research action project that used a survey to measure and address the psychological distress of healthcare workers. We explain how, through different objectives (screening of distress, adaptation of initial measures based on reported needs, active reinforcement of individual and collective resilience, reminder of availability of help, and normalization of distress), a research action project can be a form of support and is an effective way for an institution to show its pre-occupation for the mental health of its teams. The current case study highlights how an institution can provide support and the importance of the use of a combined strategy to limit the consequences of a major health crisis on the mental health of its healthcare workers. Improving the resilience of healthcare workers both in the short and long term is of the essence to maintain optimal care of patients.

Gut Microbiota-Induced Changes in ß-Hydroxybutyrate Metabolism Are Linked to Altered Sociability and Depression in Alcohol Use Disorder.

Patients with alcohol use disorder (AUD) present with important emotional, cognitive, and social impairments. The gut microbiota has been recently shown to regulate brain functions and behavior but convincing evidence of its role in AUD is lacking. Here, we show that gut dysbiosis is associated with metabolic alterations that affect behavioral (depression, sociability) and neurobiological (myelination, neurotransmission, inflammation) processes involved in alcohol addiction. By transplanting the gut microbiota from AUD patients to mice, we point out that the production of ethanol by specific bacterial genera and the reduction of lipolysis are associated with a lower hepatic synthesis of ß-hydroxybutyrate (BHB), which thereby prevents the neuroprotective effect of BHB. We confirm these results in detoxified AUD patients, in which we observe a persisting ethanol production in the feces as well as correlations among low plasma BHB levels and social impairments, depression, or brain white matter alterations.

Is (poly-) substance use associated with impaired inhibitory control? A mega-analysis controlling for confounders.

Many studies have reported that heavy substance use is associated with impaired response inhibition. Studies typically focused on associations with a single substance, while polysubstance use is common. Further, most studies compared heavy users with light/non-users, though substance use occurs along a continuum. The current mega-analysis accounted for these issues by aggregating individual data from 43 studies (3610 adult participants) that used the Go/No-Go (GNG) or Stop-signal task (SST) to assess inhibition among mostly "recreational" substance users (i.e., the rate of substance use disorders was low). Main and interaction effects of substance use, demographics, and task-characteristics were entered in a linear mixed model. Contrary to many studies and reviews in the field, we found that only lifetime cannabis use was associated with impaired response inhibition in the SST. An interaction effect was also observed: the relationship between tobacco use and response inhibition (in the SST) differed between cannabis users and non-users, with a negative association between tobacco use and inhibition in the cannabis non-users. In addition, participants' age, education level, and some task characteristics influenced inhibition outcomes. Overall, we found limited support for impaired inhibition among substance users when controlling for demographics and task-characteristics.

Predictors of blood pressure control in patients with resistant hypertension after intensive management in two expert centres: the Brussels-Torino experience.

Background: Management of resistant hypertension (RHTN) is challenging and often implies the use of complex polypharmacy and interventional therapies. The main objectives of this study were (i) to describe the characteristics of patients with RHTN referred to two expert centres; (ii) to identify predictors of blood pressure (BP) control after intensive management. Methods: We reviewed electronic medical files of all patients referred for RHTN to the Brussels and Torino centres, and extracted detailed clinical data, informations on drug adherence and psychological profile. All patients with confirmed diagnosis of RHTN, according to office and ambulatory BP monitoring (ABPM) measurements, were considered eligible. Results: 313 patients (51% men; age: 56 ± 12 years; office BP 177/98 mmHg; 24-hour ABPM 153/90 mmHg) were included. At the end of follow-up (median: 2 years [1-4]), only 26% of patients (n = 81) reached BP control. When compared to patients remaining resistant, patients eventually controlled had lower pulse pressure (71 vs. 82 mmHg, p < 0.001), less often myocardial infarction (6% vs. 20%, p < 0.005) and showed a higher recourse to cognitive reappraisal as far as emotion regulation is concerned (4.8 ± 1.1 vs. 3.9 ± 1.2, p = 0.009; ERQ Questionnaire). In a multivariate analysis looking for predictors of controlled BP, only the psychological characteristic of cognitive reappraisal (i.e., changing one's thoughts about a potentially emotion-eliciting event) remained significant (OR 2.06 [1.10; 3.84], p = 0.02). Conclusions: Even in expert centres, only a minority of patients with RHTN reached BP control, irrespective of the centre involved or the interventions applied. Patients who eventually responded to therapy had lower arterial stiffness and less cardiac organ damage. Furthermore, besides vascular damage, the single predictor of BP control was the ability to modify the emotional impact of stressful situations.

Impact of psychological profile on drug adherence and drug resistance in patients with apparently treatment-resistant hypertension.

PURPOSE: Patients with apparent treatment-resistant hypertension (a-TRH) are often poorly adherent to drug treatment and have an unusual personal history and psychological profile. The aim of this study was to identify predictors of drug adherence and drug resistance in a cohort of patients with aTRH, with emphasis on psychological characteristics. METHODS: All patients with confirmed aTRH on standardized antihypertensive treatment were eligible. Drug adherence was assessed by drug dosages in urine using Liquid Chromatography coupled with tandem Mass Spectrometry (LC-MS/MS). Drug resistance was assessed by 24-hour ambulatory blood pressure adjusted for the number of antihypertensive drugs and for drug adherence. Psychological profile was assessed using a broad array of validated questionnaires. RESULTS: The analysis included 35 consecutive patients. The proportion of adherent, partly adherent and totally non-adherent patients was 29, 40 and 31%, respectively. In regression analysis, independent predictors of poor drug adherence were recent hospital admission for hypertension, a lower ability to put things into perspective when facing negative events and a higher tendency to somatize, accounting for 51% of variability in drug adherence. Independent predictors of treatment resistance were a higher recourse to the strategies of blaming others and oneself, accounting for 37% of variability in drug treatment resistance. CONCLUSION: In patients with aTRH, poor adherence is frequent but does not entirely account for treatment resistance. Psychological characteristics appear as strong predictors of both drug adherence and drug resistance. Our results suggest that therapeutic drug monitoring and psychological evaluation should be an integral part of assessment of patients with aTRH.

Differential spontaneous recovery across cognitive abilities during detoxification period in alcohol-dependence.

OBJECTIVE: There is a lack of consensus regarding the extent to which cognitive dysfunctions may recover upon cessation of alcohol intake by alcohol-dependents (AD), and the divergent findings are most likely due to methodological differences between the various studies. The present study was aimed at conducting a very strict longitudinal study of cognitive recovery in terms of assessment points, the duration of abstinence, control of age and duration of the addiction, and by use of individual analyses in addition to mean group comparisons. Our study further focused on the 2-3 week phase of alcohol detoxification that is already known to positively affect many biological, emotional, motivational, as well as neural variables, followed by longer-term therapies for which good cognitive functioning is needed. METHODS: 41 AD inpatients undergoing a detoxification program, and 41 matched controls, were evaluated twice in terms of five cognitive functions (i.e., short-term memory, working memory, inhibition, cognitive flexibility, and verbal fluency) within a three-week interval [on the first day (T1) and the 18th day (T2) of abstinence for AD patients]. Emotional (positive and negative affectivity and depression) and motivational (craving) variables were also measured at both evaluation times. RESULTS: Although verbal fluency, short-term memory, and cognitive flexibility did not appear to be affected, the patients exhibited impaired inhibition and working memory at T1. While no recovery of inhibition was found to occur, the average working memory performance of the patients was comparable to that of the controls at T2. Improvements in emotional and motivational dimensions were also observed, although they did not correlate with the ones in working memory. Individual analysis showed that not all participants were impaired or recover the same functions. CONCLUSIONS: While inhibition deficits appear to persist after 18 days of detoxification, deficits in working memory, which is a central component of cognition, are greatly reduced after alcohol detoxification. Individual differences in the trajectory of recovery do arise however, and it might be worth implementing individual assessments of impaired functions at the end of the detoxification phase in order to maximize the chances of success in longer-term treatments and abstinence.

Gender Differences in Affects and Craving in Alcohol-Dependence: A Study During Alcohol Detoxification.

BACKGROUND: Alcohol craving is a major cause of relapse in alcohol-dependent (AD) patients. It is closely related to the high depression and anxiety symptoms that are frequently observed at the early stages of abstinence, and these comorbid symptoms might thus constitute a relapse factor when they persist after detoxification. As these negative affects are known to evolve during the detoxification process, the aim of this study was to investigate the course of the relation between affects and craving during detoxification, with a particular attention given to gender in light of the known differences in affects between AD men and women. METHODS: AD patients (n = 256) undergoing a detoxification program were evaluated for positive (PA) and negative affectivity (NA), depression and anxiety symptoms, and craving, twice within a 3-week interval (on the first [T1] and the eighteenth day [T2] of abstinence). RESULTS: Detoxification course was associated with improvements regarding NA, depression and anxiety symptoms, and craving. Moreover, these negative affects were related to craving intensity. However, for men, the relation was only present at the beginning of detoxification, while, for women, it persisted at the end of detoxification as did high levels of depression. Furthermore, only with women was the level of craving at T2 proportional to negative affects reported at T1, and depression symptoms experienced at T1 were reliable predictors of craving at T2. CONCLUSIONS: Given the importance of craving in relapse, special care should be given to improve depressive symptoms in AD women to promote long-term abstinence. Also, the remaining portion of AD women who still exhibit substantial symptoms of anxiety and depression at the end of detoxification could benefit from an integrated treatment simultaneously tackling mood and alcohol-dependence disorders.

Brain Oscillations in Sport: Toward EEG Biomarkers of Performance.

Brain dynamics is at the basis of top performance accomplishment in sports. The search for neural biomarkers of performance remains a challenge in movement science and sport psychology. The non-invasive nature of high-density electroencephalography (EEG) recording has made it a most promising avenue for providing quantitative feedback to practitioners and coaches. Here, we review the current relevance of the main types of EEG oscillations in order to trace a perspective for future practical applications of EEG and event-related potentials (ERP) in sport. In this context, the hypotheses of unified brain rhythms and continuity between wake and sleep states should provide a functional template for EEG biomarkers in sport. The oscillations in the thalamo-cortical and hippocampal circuitry including the physiology of the place cells and the grid cells provide a frame of reference for the analysis of delta, theta, beta, alpha (incl.mu), and gamma oscillations recorded in the space field of human performance. Based on recent neuronal models facilitating the distinction between the different dynamic regimes (selective gating and binding) in these different oscillations we suggest an integrated approach articulating together the classical biomechanical factors (3D movements and EMG) and the high-density EEG and ERP signals to allow finer mathematical analysis to optimize sport performance, such as microstates, coherency/directionality analysis and neural generators.

Decoding of nonverbal language in alcoholism: A perception or a labeling problem?

Alcohol-dependent patients have difficulty recognizing social cues such as emotional facial expressions, prosody, and postures. However, most researchers describing these difficulties rely on labeling tasks. It therefore remains difficult to disentangle genuine emotion-decoding problems from emotion-labeling impairments. In the present study, 35 recently detoxified alcohol-dependent patients were compared with 35 matched controls on four emotion-pairing tasks to explore the distinction between labeling and perceptual abilities. First, 2 tasks were used to assess emotion-labeling ability (labeling task) and working memory (necessary to process emotional stimuli; control matching task). Next, 2 experimental pairing tasks were used to explore unimodal, Face-face or voice-voice) and cross-modal, Face-voice or voice-face) matching abilities in the absence of any labeling requirement. Patients had difficulty accurately processing voices in unimodal tasks and correctly matching emotional stimuli in cross-modal tasks. Specifically, they did not correctly identify neutral stimuli in unimodal or cross-modal tasks and did not correctly identify fear in cross-modal tasks. Reaction times were also slower in these patients. However, accuracy and reaction time (RT) differences between patients and controls were accounted for by including anxiety and depression scores as covariates in the model. These results suggest that emotion-decoding difficulties observed in recently detoxified alcohol-dependent patients are not due to a specific emotion-labeling impairment, but rather involve perceptual difficulties or later integrative processing steps in the brain. Future studies should directly compare depressed or nondepressed alcohol-dependent patients with depressive patients to disentangle the influences of these highly comorbid disorders on nonverbal language perception.

Emotion Regulation in Alcohol Dependence.

BACKGROUND: The main aim of this study was to investigate, in alcohol-dependent (AD) patients, the use of the 5 emotion regulation strategies specified in Gross's (1998, Rev Gen Psychol, 2, 271) process model of emotion regulation with the use of a semi-structured interview allowing a detailed and high-quality assessment of emotion regulation strategies. A secondary aim was to examine the possible influence of protracted abstinence and detoxification on emotion dysregulation. Finally, the association between the level of craving and the types of regulation strategies was investigated. METHODS: Forty-four treatment-seeking AD patients with varying time spent in rehabilitation, and 26 healthy controls were interviewed using a version of the Emotion Regulation Interview (Werner et al., 2011, J Psychopathol Behav Assess, 33, 346) adapted to alcohol dependence. RESULTS: Compared to controls, AD patients reported significantly greater use of response modulation and attentional deployment, but lesser use of cognitive change. Among patients, (1) rehabilitation duration was positively correlated with the use of cognitive change and (2) the use of response modulation was positively associated with the level of craving. CONCLUSIONS: These findings clarify the specific pattern of emotion dysregulation associated with alcohol dependence. They also suggest that (1) abstinence is associated with a shift toward more adaptive emotion regulation patterns and that (2) inefficient regulation strategies may lead to craving and the maintenance of alcohol use. If these findings are confirmed through longitudinal and mediation designs, they will have important clinical implications.
