Group therapy via videoconferencing for individuals with early psychosis: A pilot study.

AIM: The COVID-19 pandemic has introduced many mental health professionals to therapy via videoconferencing. Mostly individual teletherapy has been offered and studied, although group therapy is often offered in clinics. In fact, little is known regarding group therapy's acceptability, feasibility, and potential impact when offered via videoconferencing. METHODS: This pilot study offered group cognitive-behavioural therapy for psychosis via videoconferencing to 14 individuals with early psychosis either living in remote areas or confined during the pandemic. RESULTS: The rate of consenting to the study (79%) and actual participation rates were acceptable (18.5 sessions out of 24). Although some technological obstacles were encountered, solutions offered allowed the videoconferencing group to be considered feasible for most participants and therapists. Prepost results on symptoms and self-esteem were comparable to those of other studies using the same group treatment but in-person. Alliance scores seemed similar as well. CONCLUSIONS: More studies are warranted on the efficacy of group therapy via videoconferencing. This pilot study does offer promising results, suggesting that a wider range of people with early psychosis can be reached and benefit from the advantages of receiving an evidence-based group intervention.

Exploratory Study of the Clinical Characteristics of Adolescent Girls with a History of Physical or Sexual Abuse Consulting in a Mood Disorder Clinic.

OBJECTIVE: To examine the clinical characteristics of adolescent girls consulting in a mood disorder clinic with a history of physical or sexual abuse. METHOD: A retrospective review was conducted of the charts of 55 adolescent girls consulting in a mood disorder clinic. An analysis grid was used to gather data on demographics, personal antecedents, symptoms and diagnoses. Girls with a history of physical or sexual abuse were compared with girls without such a history. Univariate analyses and a logistic regression analysis were performed. RESULTS: Adolescent girls with a history of physical or sexual abuse did not differ statistically from those without such a history in terms of depressive symptoms or type and number of diagnoses. However, proportionally more girls with a history of physical or sexual abuse presented self-harm and relational problems with their parents and peers. CONCLUSION: Both history of physical or sexual abuse and self-destructive behaviors are rooted in relational problems. The results show that these are related to one another among those adolescent girls. Clinically, these findings suggest that it is important for clinicians do a thorough exploration of self-destructive behaviors and family and peer relations when assessing depressed adolescent girls.

OBJECTIF: Examiner les caractéristiques cliniques des adolescentes consultant à une clinique des troubles de l'humeur et ayant été victime d'abus physique ou sexuel dans le passé. MÉTHODE: Une étude rétrospective de 55 dossiers d'adolescentes a été réalisée. Une grille d'analyse fut utilisée pour recueillir les données sociodémographiques, les antécédents personnels, les symptômes et les diagnostics. Les adolescentes ayant été victime d'abus physique ou sexuel dans le passé ont été comparées à d'autres adolescentes sans histoire d'abus. Une analyse univariée et une analyse de régression logistique ont été effectuées. RÉSULTATS: Les adolescentes ayant été victimes d'abus physiqueou sexuel ne différaient pas statistiquement de celles sans histoire d'abus, en ce qui a trait aux symptômes dépressifs, ou au type et au nombre de diagnostics. Toutefois, elles présentaient une proportion plus élevée d'automutilation et de problèmes relationnels avec leurs parents et leurs pairs. CONCLUSION: Un passé de victimisation physique ou sexuel et des comportements autodestructeurs traduisent des problèmes relationnels. Les résultats montrent que ces variables sont reliées l'une à l'autre chez ces adolescentes ayant été victimes d'abus physique ou sexuel. Ce résultat suggère l'importance pour le clinicien d'explorer en profondeur les comportements autodestructeurs ainsi que les relations avec la famille et les pairs lors de l'évaluation des adolescentes dépressives.

[Functional Neuroimaging Pilot Study of Borderline Personality Disorder in Adolescents]. / Neuroimagerie fonctionnelle chez l'adolescent avec un trouble de personnalité limite.

Borderline personality disorder (BPD) is being increasingly recognized by clinicians working with adolescents, and the reliability and validity of the diagnosis have been established in the adolescent population. Adolescence is known to be a period of high risk for BPD development as most patients identify the onset of their symptoms to be in the adolescent period. As with other mental health disorders, personality disorder, are thought to result from the interaction between biological and environmental factors. Functional neuroimaging studies are reporting an increasing amount of data on abnormal neuronal functions in BPD adult patients. However, no functional neuroimaging studies have been conducted in adolescents with BPD.Objectives This pilot project aims to evaluate the feasibility of a functional magnetic resonance imaging (fMRI) study coupled with clinical and psychological measures in adolescent girls with a diagnosis of BPD. It also aims to identify neuronal regions of interest (ROI) for the study of BPD in adolescent girls.Method Six female adolescents meeting DSM-IV criteria for BPD and 6 female adolescents without psychiatric disorder were recruited. Both groups were evaluated for BPD symptoms, depressive symptoms, impulsivity, affective lability, and other potential psychiatric comorbidities. We used fMRI to compare patterns of regional brain activation between these two groups as they viewed 20 positive, 20 negative and 20 neutral emotion-inducing pictures, which were presented in random order.Results Participants were recruited over a period of 22 months. The protocol was well tolerated by participants. Mean age of the BPD group and control group was 15.8 ± 0.9 years-old and 15.5 ± 1.2 years-old respectively. Psychiatric comorbidity and use of medication was common among participants in the BPD group. This group showed higher impulsivity and affective lability scores. For the fMRI task, BPD patients demonstrated greater differences in activation than controls, when viewing negative pictures compared with neutral pictures, in limbic regions (amygdala and right hippocampus and parahippocampal areas) as well as in the superior frontal gyrus, right precentral gyrus and cerebellum, while control group showed greater activation in left precentral gyrus and right orbitofrontal area. Viewing positive pictures compared with neutral pictures led to increased activation of the left hippocampus and both parahippocampal regions, as well as middle cingulate cortex, superior temporal gyrus and cerebellum in the BPD group. In the control group, positive-scene viewing led to increased activity in the left superior parietal gyrus and right middle/superior temporal gyrus.Conclusion Limbic regions and areas from the prefrontal and orbitofrontal cortex are potential ROI for the study of the neurophysiology of BPD in female adolescents. The larger studies are needed to better understand the neural features found in these young patients.

Treatment Options for the Cardinal Symptoms of Disruptive Mood Dysregulation Disorder.

OBJECTIVE: DSM-5 has added a new developmentally appropriate child and adolescent mood disorder subtype called disruptive mood dysregulation disorder (DMDD). The core features of DMDD are temper outbursts (manifested by either verbal rages and/or physical aggression) and unrelenting irritability or anger. Currently, the literature is lacking a thorough review of the possible treatment options for the cardinal symptoms constituting DMDD. The objective of this article is to provide a thorough review of peer-reviewed studies on the subject of pharmacological treatment options for children and adolescents with the cardinal symptoms of DMDD. METHODS: Relevant articles for this study were obtained through Pubmed, Medline, PsychINFO and PsychINDEXplus using the key words: "adolescents," "children," "paediatric," "youth," "irritability," "temper outbursts," "aggression," "rage," "disruptive behaviour," "treatment," "dysphoria," "autism," "mental retardation/intellectual disability," "impulsivity," "ADHD," "oppositional defiant disorder," and "conduct disorder." A total of 823 studies were generated; only English studies focusing on pharmacological treatment were retained. RESULTS: Currently there are no established guidelines or thorough reviews summarizing the treatment of DMDD. Pharmacotherapeutic treatment options of both aggression and chronic irritability include: antidepressants/selective norepinephrine reuptake inhibitors, mood stabilizers, psychostimulants, antipsychotics, and alpha-2 agonists. CONCLUSION: Treatment options of severe, persistent irritability in youth are numerous, and a consensual treatment algorithm has not yet emerged from the literature. Further studies and clinical trials are warranted to determine efficacious and safe treatment modalities.

OBJECTIF: Le DSM-5 a ajouté un nouveau sous-type de trouble de l'humeur adapté au développement des enfants et des adolescents qui porte le nom de trouble disruptif avec dysrégulation de l'humeur (TDDH). Les principales caractéristiques du TDHE sont des accès de colère (manifestés soit par des rages verbales et/ou une agression physique) et une irritabilité ou une colère persistante. À l'heure actuelle, la littérature ne présente pas de revue approfondie des options de traitement possibles des symptômes cardinaux constituant le TDHE. L'objectif de cet article est d'offrir une revue approfondie des études révisées par des pairs sur le sujet des options de traitement pharmacologique pour les enfants et les adolescents présentant les symptômes cardinaux du TDHE. MÉTHODES: Les articles pertinents pour cette étude ont été obtenus dans Pubmed, Medline, PsychINFO et PsychINDEXplus à l'aide des mots clés: « adolescents ¼, « enfants ¼, « pédiatrie ¼, « jeunesse ¼, « irritabilité ¼, « accès de colère ¼, « agressivité ¼, « rage ¼, « comportement perturbateur ¼, « traitement ¼, « dysphorie ¼, « autisme ¼, « retard mental/déficience intellectuelle ¼, « impulsivité ¼, « TDAH ¼, « trouble oppositionnel avec provocation ¼, et « trouble des conduites ¼. Au total, 823 études ont été relevées; seulement les études en anglais portant sur le traitement pharmacologique ont été retenues. RÉSULTATS: À l'heure actuelle, il n'y a pas de lignes directrices établies ou de revues approfondies qui résument le traitement du TDHE. Les options de traitement pharmacologique de l'agressivité et de l'irritabilité chronique sont notamment: les antidépresseurs/inhibiteurs spécifiques du recaptage de la noradrénaline, les stabilisateurs de l'humeur, les psychostimulants, les antipsychotiques, et les agonistes alpha-2. CONCLUSION: Les options de traitement de l'irritabilité grave et persistante chez les adolescents sont nombreuses, et un algorithme de traitement consensuel n'a pas encore été dégagé de la littérature. D'autres études et essais cliniques sont nécessaires pour déterminer des modes de traitement efficaces et sûrs.

Arterial stiffness and dialysis calcium concentration.

Arterial stiffness is the major determinant of isolated systolic hypertension and increased pulse pressure. Aortic stiffness is also associated with increased cardiovascular morbidity and mortality in patients with chronic kidney disease, hypertension, and general population. Hemodynamically, arterial stiffness results in earlier aortic pulse wave reflection leading to increased cardiac workload and decreased myocardial perfusion. Although the clinical consequence of aortic stiffness has been clearly established, its pathophysiology in various clinical conditions still remains poorly understood. The aim of the present paper is to review the studies that have looked at the impact of dialysis calcium concentration on arterial stiffness. Overall, the results of small short-term studies suggest that higher dialysis calcium is associated with a transient but significant increase in arterial stiffness. This calcium dependant increase in arterial stiffness is potentially explained by increased vascular smooth muscle tone of the conduit arteries and is not solely explained by changes in mean blood pressure. However, the optimal DCa remains to be determined, and long term studies are required to evaluate its impact on the progression of arterial stiffness.

Impact of dialysate calcium concentration on the progression of aortic stiffness in patients on haemodialysis.

BACKGROUND: Higher dialysate calcium (DCa) can result in an acute and transient increase in arterial stiffness. The aim of the present study is to evaluate the impact of DCa on the progression of arterial stiffness, calcium balance and bone metabolism in haemodialysis (HD) patients over a 6-month period. Method. We randomly assigned 30 patients on chronic HD to be dialysed with a DCa of 1.12 or 1.37 mmol/L for a period of 6 months. Aortic stiffness and brachial stiffness were respectively measured by carotid-femoral pulse wave velocities (cf-PWV) and carotid-radial pulse wave velocity (cr-PWV) at baseline and at 3 and 6 months. Central pulse pressure (PP) and augmentation index were determined by radial artery tonometry. Dialysis calcium balance and parathyroid hormone (PTH) were measured monthly. Procollagen type-1 amino-terminal propeptide (P1NP) and C-terminal telopeptide of type-I collagen (CTX) were measured as markers of bone formation and resorption, respectively. Data was analysed by linear mixed model. RESULTS: Twenty-seven patients (66 ± 13 years old) with a mean duration of HD of 5.8 ± 3.6 months completed the study. At baseline, the groups were similar with respect to age, serum levels of calcium, phosphate and PTH, blood pressure (BP), cf-PWV and cr-PWV. The cf-PWV at baseline and 3 and 6 months were, respectively, 13.4 ± 4.2, 14.7 ± 3.31 and 13.6 ± 2.5 m/s in the DCa 1.12 group and 14.6 ± 5.9, 15.8 ± 7.8 and 17.0 ± 7.0 m/s in the DCa 1.37 group. After correction for mean BP, cf-PWV increased with DCa 1.37 as compared to DCa 1.12 (Time-DCa interaction P = 0.002). However, there were no significant effects of DCa on progression of cr-PWV, central PP or augmentation index. During the intervention period, the mean PTH was slightly higher in the DCa 1.12 group as compared to the DCa 1.37 group (325 ± 185 versus 211 ± 128 ng/L, P = 0.054), and dialysis calcium balance was -8.1 ± 4.4 versus -0.2 ± 4.7 mmol/session, respectively, in groups with DCa 1.12 and DCa 1.37 (P = 0.0001). Treatment with DCa 1.12 mmol/L resulted in increasing levels of CTX as compared to DCa 1.37 (P = 0.02), whereas the P1NP levels did not change significantly in either group. CONCLUSIONS: In this study, aortic stiffness progressed with DCa 1.37, while it remained stable with DCa 1.12 over a 6-month period. These results suggest that higher DCa concentrations could be a risk factor for the progression of aortic stiffness in HD patients. In the context of limited oral calcium, the long-term safety of DCa 1.12 on bone metabolism remains to be established.

The impact of arteriovenous fistulas on aortic stiffness in patients with chronic kidney disease.

BACKGROUND: The creation of arteriovenous fistulas (AVF) in patients with advanced chronic kidney disease (CKD) has been shown to have adverse effects on their central pulse wave profile suggesting a likely increase in arterial stiffness. The aim of the present study was to directly evaluate the effect of AVF on arterial stiffness. Method. Thirty-one stage-5 CKD patients underwent haemodynamic assessment prior to and 3 months after creation of AVF. Haemodynamic assessment included measurement of blood pressure (BP), central and carotidal pulse wave profile analysis, and carotido-femoral and carotido-radial pulse wave velocities (PWV). Pre-AVF and post-AVF haemodynamic parameters were compared using the Wilcoxon signed-rank test or the paired Student t-test as appropriate. Pearson correlations, single and multiple linear regressions, were used to determine the association between variables. RESULTS: After creation of AVF, peripheral and central BPs decreased without significant change in heart rate (HR) or pulse pressure. Carotido-femoral PWV ((c-f)PWV) fell from 13.2 +/- 4.1 to 11.7 +/- 3.1 m/s (P < 0.001). There was an increase in the central augmentation index (20.8% +/- 11.5 versus 23.7% +/- 11.6, P = 0.07) of borderline significance, and a significant reduction in the subendocardial viability ratio (153% +/- 34 versus 143% +/- 32, P < 0.05), which was mainly the result of a decrease in the diastolic pressure time index (DPTI) without any significant change in the diastolic duration. The reduction of (c-f)PWV was explained by changes in mean BP and HR (R(2) = 0.29). The reduction in DPTI was related to changes in central diastolic BP and changes in end-systolic BP (adjusted R(2) = 0.87). The significant improvement in aortic stiffness was mostly the result of the relative reduction of (c-f)PWV in the subgroup of patients with baseline (c-f)PWV above the median value of 13 m/s. CONCLUSION: The creation of AVF is associated with a passive improvement of aortic stiffness especially in patients with stiffer arteries. This improvement in arterial stiffness could potentially be beneficial to the cardiovascular system despite an associated deterioration in the aortic pulse wave profile.
