Reliable predictors for electroconvulsive therapy (ECT) effectiveness would allow a more precise and personalized approach for the treatment of major depressive disorder (MDD). Prediction models were created using a priori selected clinical variables based on previous meta-analyses. Multivariable linear regression analysis was used, applying backwards selection to determine predictor variables while allowing non-linear relations, to develop a prediction model for depression outcome post-ECT (and logistic regression for remission and response as secondary outcome measures). Internal validation and internal-external cross-validation were used to examine overfitting and generalizability of the model's predictive performance. In total, 1892 adult patients with MDD were included from 22 clinical and research cohorts of the twelve sites within the Dutch ECT Consortium. The final primary prediction model showed several factors that significantly predicted a lower depression score post-ECT: higher age, shorter duration of the current depressive episode, severe MDD with psychotic features, lower level of previous antidepressant resistance in the current episode, higher pre-ECT global cognitive functioning, absence of a comorbid personality disorder, and a lower level of failed psychotherapy in the current episode. The optimism-adjusted R² of the final model was 19%. This prediction model based on readily available clinical information can reduce uncertainty of ECT outcomes and hereby inform clinical decision-making, as prompt referral for ECT may be particularly beneficial for individuals with the above-mentioned characteristics. However, despite including a large number of pretreatment factors, a large proportion of the variance in depression outcome post-ECT remained unpredictable., (© 2024.

Introduction: Major depressive disorder (MDD) is a common psychiatric disorder. Despite several treatment options, a subgroup of patients will not respond to the commonly used antidepressant treatments and thus express treatment resistance (TRD). TRD can be quantified with the Dutch Measure for Treatment Resistance in Depression (DM-TRD). Electroconvulsive therapy (ECT) is an effective treatment for MDD, also in TRD. Yet, the position of ECT as "treatment-of-last-resort" may decrease the likelihood of beneficial outcome. Our aim was to investigate the association between treatment resistance and outcome and course of ECT., Methods: We performed a retrospective, multicenter cohort study with 440 patients of which data was retrieved from patient records as collected in the Dutch ECT Cohort database. Linear and logistic regression models were used to explore the association between level of treatment resistance and outcome of ECT. Median split was used to explore the differences between high and low level of TRD and course of treatment., Results: A higher DM-TRD score was associated with significantly smaller reduction of depression symptoms (R 2  = 0.160; β = -2.968; p < 0.001) and lower chance of response (OR = 0.821 [95 CI: 0.760-0.888]; β = -0.197; p < 0.001). Low level TRD patients underwent fewer ECT sessions (mean 13 ± 6 SD vs. 16 ± 7 SD; p < 0.001) and fewer switches from right unilateral tot bifrontotemporal electrode placement (29% vs. 40%; p = 0.032)., Conclusion: Reserving ECT as "treatment-of-last-resort" in the treatment algorithm for MDD seems questionable, because in our study lower level of treatment resistance predicted more beneficial ECT-outcome. Moreover, providing ECT in less treatment resistant patients showed fewer needed ECT-sessions and less switches to BL electrode placement, which may decrease the risk for cognitive side-effects., (© 2023 The Authors.

Background: Cognitive side-effects are an important reason for the limited use of electroconvulsive therapy (ECT). Cognitive side-effects are heterogeneous and occur frequently in older persons. To date, insight into these side-effects is hampered due to inconsistencies in study designs and small sample sizes. Among all cognitive side-effects, confusion and delirious states are especially troublesome for patients, relatives and clinicians. In particular inter-ictal delirium-like states are worrisome, since they may lead to premature treatment discontinuation. Besides a need for further insight into determinants of cognitive side-effects of ECT, there is a great need for treatment options., Methods and Design: The Rivastigmine for ECT-induced Cognitive Adverse effects in Late Life depression (RECALL) study combines a multicenter, prospective cohort study on older patients with depression, treated with ECT, with an embedded randomized, placebo-controlled cross-over trial to examine the effect of rivastigmine on inter-ictal delirium. Patients are recruited in four centers across the Netherlands and Belgium. We aim to include 150 patients into the cohort study, in order to be able to subsequently include 30 patients into the trial. Patients are included in the trial when inter-ictal delirium, assessed by the Confusion Assessment method (CAM), or a drop in Mini Mental State Examination (MMSE) score of ≥4 during ECT, develops. In the cohort study, comprehensive measurements of ECT-related cognitive side-effects-and their putative determinants-are done at baseline and during the ECT-course. The primary outcome of the clinical trial is the effectiveness of rivastigmine on inter-ictal delirium-severity, assessed with a change in the Delirium Rating Scale-Revised-98. Secondary outcomes of the clinical trial are several ECT-characteristics and side-effects of rivastigmine., Discussion: This study is the first clinical trial with a focus on ECT-induced, inter-ictal delirium. The cohort provides the basis for recruitment of patients for the cross-over trial and additionally provides an excellent opportunity to unravel cognitive side-effects of ECT and identify putative determinants.

Aims: The clinical relevance of diabetes-distress is increasingly recognized, but little is known about the efficacy of interventions specifically targeted to treat elevated diabetes-distress. Therefore, this systematic review sought to determine the efficacy of psychological interventions aimed at treating elevated diabetes-distress in people with Type 1 or Type 2 diabetes., Methods: We systematically searched literature from five databases. Randomized controlled trials (RCTs) with an English abstract, describing the results of a psychological intervention in adults with diabetes were included. Articles were eligible for inclusion if the primary outcome was diabetes-distress measured by the Problem Areas in Diabetes Scale (PAID-5/PAID-20) or the Diabetes Distress Scale (DDS-17). Only mean group diabetes-distress values above cut-off at baseline or the results of a subgroup above cut-off (PAID-5 ≥ 8, PAID-20 ≥ 40 or DDS-17 ≥ 3) were included., Results: The search yielded 8907 articles. After removing 2800 duplicates, 6107 articles remained. Titles and abstracts were screened, leaving 394 potential articles of interest, nine of which were RCTs. In a random-effects meta-analysis, the pooled effect size for diabetes-distress was 0.48 (Cohen's d), Z = 3.91, P < 0.0001. Statistical heterogeneity was I² = 46.67% (confidence intervals 45.06% to 48.28%). Diabetes-tailored psychological interventions reduced HbA 1c (Cohen's d = 0.57), whereas mindfulness-based interventions did not (Cohen's d = 0.11)., Conclusions: This systematic review shows that specifically diabetes-tailored psychological interventions are effective in reducing elevated diabetes-distress and HbA 1c . More rigorous studies are warranted to establish the full potential of these interventions. PROSPERO database registration ID: CRD42017075290., (© 2018 Diabetes UK.)

Background: Research, aimed at improving the continuity of care after hospital discharge following attempted suicide focuses on the effectiveness of the interventions. Little attention has been paid to patients who immediately decline guidance to advised post-discharge care. We aimed to identify differences between accepters and decliners of guidance to care (GtC) in relation to the characteristics of patients who presented at the emergency department (ED) of an urban hospital in the Netherlands after attempted suicide., Method: This cross-sectional study included all patients who presented at the ED of OLVG-West Amsterdam with a suicide attempt or intentional self-harm and were referred for psychiatric evaluation. Data were collected over a period of twenty months using a semi-structured questionnaire. Subgroups were described in relation the acceptance of GtC using univariate and multivariate logistic regression analyses., Results: In total, 257 patients were included. GtC was accepted by 77%. Suicide attempters who reported loneliness as reason for the attempt showed a positive relation to acceptance. No indication was found that patients at higher risk for suicide are more reluctant to accept GtC. Suicide attempters with a non-Western ethnicity, especially patients with a Turkish/Moroccan ethnicity, declined contact by the GtC nurse significantly more often. In addition, patients who currently did not receive care were significantly more often of non-Western ethnicity and younger than 25., Conclusion: Acceptance of GtC is high among patients who presented at the ED after attempted suicide. The patients who were the most reluctant to accept GtC were young suicide attempters of non-Western ethnicity who were not in current care. As this study is the first to address the acceptance of GtC, we point out two lines of inquiry for further research. First, reasons to accept or decline need to be investigated further since only interventions that are accepted by patients have a chance to improve clinically relevant outcome. Second, follow-up research is warranted comparing the adherence to advised post-discharge care and attempted or completed suicide among accepters versus decliners of GtC in various ethnic and sociodemographic subgroups.
