Background: The purpose of this exploratory study is to examine the role of sociodemographic, clinical, and cognitive - both objective and subjective - factors in overall and in specific domains of psychosocial functioning, in patients with depression at different clinical states of the disease (remitted and non-remitted).
Methods: A sample of 325 patients with major depressive disorder, 117 in remission and 208 in non-remission, were assessed with a semi-structured interview collecting sociodemographic, clinical, cognitive (with neuropsychological tests and the Perceived Deficit Questionnaire), and functional (Functioning Assessment Short Test) characteristics. Backward regression models were conducted to determine associations of global and specific areas of functioning with independent factors, for both clinical states.
To replicate previous findings and to investigate related clinical factors of long-term benefits and safety of subcallosal cingulate gyrus deep brain stimulation (SCG-DBS) for treatment-resistant depression (TRD). Sixteen patients with TRD (with either major depressive disorder or bipolar disorder, and criteria) receiving chronic SCG-DBS were followed for up to 11 years (January 2008 to June 2019). Demographic, clinical, and functioning data were collected pre-surgery and during the follow-up.

Cognitive dysfunction has been proposed to be a primary mediator of functional impairment. Therefore, the new non-pharmacological procognitive strategy INtegral Cognitive REMediation for Depression (INCREM) has been developed with the aim of targeting cognitive and psychosocial functioning.

Despite the considerable amount of research evidence on the significant role of subjective happiness on mental health, there is no psychometric study of the Subjective Happiness Scale (SHS) in psychiatric samples. This study was aimed at exploring the psychometric properties of the SHS in a Spanish sample of patients with depressive disorders. Participants were 174 patients with a depressive disorder (70% diagnosed as major depressive disorder) who completed the SHS, the Quick Inventory of Depressive Symptomatology-Self Report (QIDS-SR), and the EQ-5D Visual Analogue Scale (EQ-5D VAS).

Nevertheless, results have been inconsistent, focusing on fully developed major depression neglecting first episode patients (FED). Longitudinal studies have also been rare and with short follow-up periods.

Deep brain stimulation (DBS) has been used in treatment resistant patients with other psychiatric disorders, but there is a lack of trials in schizophrenia, partly due to uncertainties over where to site the electrodes. This trial aimed to examine the effectiveness of nucleus accumbens (NAcc) and subgenual anterior cingulate cortex (subgenual ACC) targeted DBS; the primary outcome measure was PANSS total score, as assessed fortnightly.

This study investigates the efficacy of an INtegral Cognitive REMediation (INCREM) that includes a combination of a Functional Remediation (FR) strategy plus a Computerized Cognitive Training (CCT) in order to improve not only cognitive performance but also the psychosocial functioning and the quality of life.
Methods: A single blind randomized controlled clinical trial in 81 patients with a diagnosis of MDD in clinical remission or in partial remission.
Exploring depressive symptom severity is progressively shifting from the traditional assessment of symptom domains to detailed examination of individual symptoms. This study aimed at determining whether using an alternative scoring method (i.e.

Despite safety concerns raised by the European Medicines Agency (EMA), evidence supporting QT-lengthening effects of escitalopram is far to be conclusive. We aimed to evaluate the relationship between escitalopram plasma levels (Escit-PL) and corrected QT-interval length (QTc-length) in 91 outpatients recruited from a hospital setting. Fifteen patients had an abnormally prolonged QTc-interval, and 3 had QTc-intervals ≥500 ms.

The aim of this study was to examine the prognostic potential of clinical and structural magnetic resonance imaging (sMRI) in the long-term MDD clinical outcomes (COs).
Methods: Forty-nine MDD patients were grouped into one of four different CO categories according to their trajectory: recovery, partial remission, remission recurrence, and chronic depression.
Background: To date, antidepressant drugs show limited efficacy, leaving a large number of patients experiencing severe and persistent symptoms of major depression. Previous open-label clinical trials have reported significant sustained improvements with deep brain stimulation (DBS) of the subcallosal cingulate gyrus (SCG) in patients with severe, chronic treatment-resistant depression (TRD). This study aimed to confirm the efficacy and measure the impact of discontinuation of the electrical stimulation.

Background: Positron emission tomography (PET) studies have shown that the antidepressant effect of chronic deep brain stimulation (DBS) of the subcallosal cingulate gyrus (SCG) may be consequence of modifications of brain metabolism at key structures involved in depression. Like clinical benefits, these metabolic changes may reverse when the stimulation is discontinued, even preceding clinical worsening. However no data on immediate effects of DBS discontinuation are available.

This is a psychometric study of the Spanish version of the Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR16) in a clinical sample.
Method: One-hundred and seventy-three patients (65% women) with a psychiatric disorder including depressive symptoms were recruited.
Introduction: Clozapine is a second-generation antipsychotic drug that is mainly prescribed for treatment-resistant psychotic disorder. It is known to have several undesirable side effects, including cognitive functional complaints, such as memory or attention. The aim of this work is to study if reduction of the dosage within the therapeutic margins could improve cognitive performance of Clozapine treated patients.

This study was aimed at exploring the psychometric properties of the Spanish version of the Clinically Useful Depression Outcome Scale (CUDOS) in a clinical sample.
Method: Participants were 162 patients (72% women) with a mood disorder (86% diagnosed as major depressive disorder).
Background: Findings of brain structural changes in major depressive disorder are still inconsistent, partly because some crucial clinical variables have not been taken into account.
Aims: To investigate the effect of major depressive disorder on grey matter volumes.
Method: Voxel-based morphometry was used to compare 66 patients with depression at different illness stages (22 each with first-episode, remitted-recurrent and treatment resistant/chronic depression) with 32 healthy controls.
Background: Smaller hippocampal volumes in major depressive disorder (MDD) have been linked with earlier onset, previous recurrences and treatment refractoriness. The aim of our study was to investigate metabolite abnormalities in the hippocampus associated with past depressive illness burden.
Methods: Glutamate/glutamine (Glx), N-acetylaspartate (NAA) and choline (Cho), potential markers of glial/neuronal integrity and membrane turnover, respectively, were measured in adults with depression and healthy controls using a 3 T magnetic resonance spectroscopy scanner.
Deep brain stimulation (DBS) is currently tested as an experimental therapy for patients with treatment-resistant depression (TRD). Here we report on the short- and long-term (1 yr) clinical outcomes and tolerance of DBS in eight TRD patients. Electrodes were implanted bilaterally in the subgenual cingulate gyrus (SCG; Broadman areas 24-25), and stimulated at 135 Hz (90-μs pulsewidth).

Given the controversial previous findings with enhancing strategies such as pindolol, we examined whether the speed of selective serotonin reuptake inhibitor (SSRI) action can be truly accelerated with optimized pindolol dosage. Additionally, we aimed at elucidating whether pindolol benefits emerge, particularly in a population with nonresistant depression.

Measurement of brain metabolites by means of Magnetic Resonance spectroscopy (MRS) can indirectly deliver information about glial and neuronal integrity or potential cellular loss. The aim of this study was to investigate whether Glutamate (Glu), Choline (Cho) and total N-acetylaspartate (total-NAA) levels in the vmPFC differed among MDD patients in distinct stages of illness and healthy controls.
