Development and validation of a meta-learner for combining statistical and machine learning prediction models in individuals with depression
(2022-05)The debate of whether machine learning models offer advantages over standard statistical methods when making predictions is ongoing. We discuss the use of a meta-learner model combining both approaches as an alternative. ... -
Development and validation of a prediction model for the probability of responding to placebo in antidepressant trials: a pooled analysis of individual patient data
(2019-02)Background: Identifying potential placebo responders among apparent drug responders is critical to dissect drug-specific and nonspecific effects in depression. Objective: This project aimed to develop and test a prediction ... -
A Dissociation of the Acute Effects of Bupropion on Positive Emotional Processing and Reward Processing in Healthy Volunteers
(2018-10)Background: Previous research indicates that antidepressants can restore the balance between negative and positive emotional processing early in treatment, indicating a role of this effect in later mood improvement. However, ... -
A dose-effect network meta-analysis model: an application in antidepressants
(2021-04)Network meta-analysis (NMA) has been used to answer a range of clinical questions about the preferable intervention for a given condition. Although the effectiveness and safety of pharmacological agents depend on the dose ... -
Dose–effect meta-analysis for psychopharmacological interventions using randomised data
(2022-01)Objective The current practice in meta-analysis of the effects of psychopharmacological interventions ignors the administered dose or restricts the analysis in a dose range. This may introduce unnecessary uncertainty and ... -
A dose–effect network meta-analysis model with application in antidepressants using restricted cubic splines
(2022-02)Network meta-analysis has been used to answer a range of clinical questions about the preferred intervention for a given condition. Although the effectiveness and safety of pharmacological agents depend on the dose ... -
Effect of acute citalopram on self-referential emotional processing and social cognition in healthy volunteers
(2020-10)Background Depression is characterised by negative views of the self. Antidepressant treatment may remediate negative self-schema through increasing processing of positive information about the self. Changes in affective ... -
Effect of selective serotonin reuptake inhibitor treatment following diagnosis of depression on suicidal behaviour risk: a target trial emulation
(2023-07)There is concern regarding the impact of selective serotonin reuptake inhibitors (SSRIs) on suicidal behaviour. Using the target trial framework, we investigated the effect on suicidal behaviour of SSRI treatment following ... -
The effect of sertraline on emotional processing: secondary analyses of the PANDA randomised controlled trial
(2021-01)Background. According to the cognitive neuropsychological model, antidepressants reduce symptoms of depression and anxiety by increasing positive relative to negative information processing. Most studies of whether ... -
Effect of the NMDA receptor partial agonist, d-cycloserine, on emotional processing and autobiographical memory
(2020-04)Background: Studies suggest that d-cycloserine (DCS) may have antidepressant potential through its interaction with the glycine site of the N-Methyl-D-aspartate receptor (NMDAR); however clinical evidence of DCS’s efficacy ... -
Effectiveness and Acceptability of Cognitive Behavior Therapy Delivery Formats in Adults With Depression A Network Meta-analysis
(2019-04)Importance Cognitive behavior therapy (CBT) has been shown to be effective in the treatment of acute depression. However, whether CBT can be effectively delivered in individual, group, telephone-administered, guided ... -
Effects of escitalopram therapy on functional brain controllability in major depressive disorder
(2022-04)Antidepressant drugs are the mainstay of treatment for patients with major depressive disorders (MDD). Given the critical role of the underlying neural control mechanism in the physiopathology of depression, this study ... -
Efficacy and acceptability of next step treatment strategies in adults with treatment-resistant major depressive disorder: protocol for systematic review and network meta-analysis
(2022-04)For major depression, a one-size-fits-all treatment does not exist. Patients enter a ‘trial-and-change’ algorithm in which effective therapies are subsequently applied. Unfortunately, an empirically based order of treatments ... -
Endocannabinoid system mediates the association between gut-microbial diversity and anhedonia/amotivation in a general population cohort
(2021-05)Anhedonia and amotivation are debilitating symptoms and represent unmet therapeutic needs in a range of clinical conditions. The gut-microbiome-endocannabinoid axis might represent a potential modifiable target for ... -
ENIGMA MDD: Seven Years of Global Neuroimaging Studies of Major Depression through Worldwide Data Sharing
(2019-10)A key objective in the field of translational psychiatry over the past few decades has been to identify the brain correlates common to individuals with major depressive disorder (MDD). Identifying measurable indicators ... -
An Experimental Medicine Investigation of the Effects of Subacute Pramipexole Treatment on Emotional Information Processing in Healthy Volunteers
(2021-08)Treatment with the dopamine D2/D3 receptor agonist pramipexole has demonstrated promising clinical effects in patients with depression. However, the mechanisms through which pramipexole might alleviate depressive symptoms ... -

Fifty years on: Serotonin and depression
(2023-03)It has been over 50 years since the original serotonin hypothesis was proposed by the British Psychiatrist Alec Coppen. Recently, some authors have questioned the validity of the hypothesis. In this narrative review, we ... -
Glucocorticoid ultradian rhythmicity differentially regulates mood and resting state networks in the human brain: A randomised controlled clinical trial
(2021-02)Adrenal glucocorticoid secretion into the systematic circulation is characterised by a complex rhythm, composed of the diurnal variation, formed by changes in pulse amplitude of an underlying ultradian rhythm of short ... -
How effective is augmentation with psychotherapy as a next-step option for treatment-resistant depression?
