Creation of a brief group intervention to reduce caregivers burden in an intensive home treatment unit

Introduction

Intensive home-treatment (IHT) for people experiencing a mental health crisis has been progressively established in many European countries as an alternative to in-ward treatment. However, the management of acute episodes at home can cause burden in the caregivers of these patients.

Objectives

To create a brief group intervention (BGI) to reduce burden in the caregivers of the patients admitted to an IHT unit.

Methods

A preliminary version of the BGI (BGI 1.0) was designed based on literature’s review. It consisted of 4 sessions of 90 minutes (one per week), on-line (COVID-19), focused on caregivers burden, stress and self-care, communication skills, and self-compassion. All the caregivers of the patients admitted for IHT from 10/01/2020 to 06/01/2021 were offered the BGI 1.0. At the end of the intervention, participants (caregivers and therapists) were asked about their opinion on its contents and usefulness.

Results

A total of 31 caregivers received the BGI 1.0. Most of them felt satisfied with the intervention. Opinions varied as to which contents should be expanded or included. The therapists thought that the number of sessions should be increased to take a closer look at some contents or to include new ones. They also believed that the on-line format hindered the adherence and the interaction between the participants.

Conclusions

The BGI 1.0 seems to be a good starting point to design the final version of the intervention. However, an exhaustive assessment of the construct of burden in a larger sample of caregivers should be performed prior to its design.

Changes over the last 15 years in the psychopharmacological management of persons with borderline personality disorder

OBJECTIVE

To describe the pharmacological management of borderline personality disorder (BPD) in Spain from 2001 through 2016, the factors associated with prescriptions, and changes in pharmacotherapy over this time period.

METHODS

Retrospective, cross-sectional, observational study conducted in a sample of 457 patients with BPD consecutively admitted to a specialist BPD Program between January 2001 and November 2016. Data on sociodemographic and clinical variables, as well as pharmacological treatment upon the admission to the programme, were used to describe pharmacological prescriptions, the factors associated with these medications, and changes in prescription over the last 15 years.

RESULTS

Most (88.4%) patients were on pharmacological treatment, with 53.8% of persons taking ≥3 medications. No significant changes in these percentages were observed over the study period. The use of tricyclic antidepressants and benzodiazepines decreased, while the use of atypical antipsychotics increased. Axis I comorbidity was the main factor associated with pharmacological treatment and polypharmacy.

CONCLUSIONS

This study provides further evidence confirming the worldwide overuse of prescription medications for BPD and shows that there has been a shift in the prescription pattern in the last 15 years. These results suggest that real clinical practice only partially adheres to clinical treatment guidelines.

Volumetric MRI study of the habenula in first episode, recurrent and chronic major depression

The habenula (Hb) can play an important role in major depressive disorder (MDD) as it is a key node between fronto-limbic areas and midbrain monoaminergic structures. In vivo neuroimaging studies have shown reductions in Hb volume in a post-mortem sample of patients with affective disorders but findings in unipolar MDD are not consistent. The current study aimed to investigate whether the Hb volume differed between patients with different stages of unipolar MDD and healthy subjects. We also explored differences in grey (GM) and white matter (WM) volumes and potential age and gender effects. High-resolution images were acquired using a 3T-scanner from 95 participants (21 with first-episode MDD; 20 with remitted-recurrent MDD; 20 with treatment-resistant/chronic MDD; and 34 healthy controls).Two researchers blinded to clinical data manually delineated habenular nuclei, with excellent inter-rater agreement. Multivariate analysis of covariance revealed a significant group-by-gender interaction (F9,258=2.22; p=0.02). Univariate effects emerged for Hb-WM volumes (F3,86=3.12; p=0.03) but not for total Hb volumes (F3,86=0.59; p=0.62) or Hb-GM volumes (F3,86=2.01; p=0.12). Women with a first-episode MDD had greater Hb-WM volumes than healthy controls and patients with treatment-resistant/chronic MDD (p<0.01). These findings remained unaltered when controlled for total intracranial volume or medication load. Our results do not support decreased total Hb volumes in unipolar MDD, in patients with first-episode or in patients with long-lasting recurrent or chronic depression. However, the increased Hb-WM volume we observed in women with a first-episode suggests involvement of Hb and its projections in early stages of the recovery process and in the course of MDD.

Microstructural white-matter abnormalities associated with treatment resistance, severity and duration of illness in major depression

BACKGROUND

Although white-matter abnormalities have been reported in middle-aged patients with major depressive disorder (MDD), few data are available on treatment-resistant MDD and the influence of relevant variables related to clinical burden of illness is far from being well established.

METHOD

The present study examined white-matter microstructure in a sample of 52 patients with MDD in different stages (treatment-resistant/chronic MDD, n = 18; remitted-recurrent MDD, n = 15; first-episode MDD, n = 19) and 17 healthy controls, using diffusion tensor imaging with a tract-based spatial statistics approach. Groups were comparable in age and gender distribution, and results were corrected for familywise error (FWE) rate.

RESULTS

Widespread significant reductions of fractional anisotropy (FA) - including the cingulum, corpus callosum, superior and inferior longitudinal fascicule - were evident in treatment-resistant/chronic MDD compared with first-episode MDD and controls (p < 0.05, FWE-corrected). Decreased FA was observed within the ventromedial prefrontal region in treatment-resistant/chronic MDD even when compared with the remitted-recurrent MDD group (p < 0.05, FWE-corrected). Longer duration of illness (β = -0.49, p = 0.04) and higher depression severity (at a trend level: β = -0.26, p = 0.06) predicted lower FA in linear multiple regression analysis at the whole-brain level. The number of previous episodes and severity of symptoms were significant predictors when focused on the ventromedial prefrontal area (β = -0.28, p = 0.04; and β = -0.29, p = 0.03, respectively). Medication effects were controlled for in the analyses and results remained unaltered.

CONCLUSIONS

Our findings support the notion that disruptions of white-matter microstructure, particularly in fronto-limbic networks, are associated with resistance to treatment and higher current and past burden of depression.
