For individuals with treatment-resistant depression (TRD), transcranial magnetic stimulation (TMS) has become a well-established approach. In the past decade, intravenous (IV) racemic ketamine has also emerged as a potential treatment for TRD. Currently, little data is available on the clinical effects of IV racemic ketamine in TRD patients who experienced TMS-failure.
Twenty-one (21) TRD patients who had failed to respond to a standard course of high-frequency left-dorsolateral prefrontal cortex TMS were subsequently scheduled to received IV racemic ketamine infusions. The IV racemic ketamine protocol consisted of 0,5 mg/kg infusions over 60 min, 3 times a week over 2 weeks.
Treatment was safe with minimal side-effects. Mean baseline MADRS score was 27.6 ± 6.4 (moderate depression), decreasing down to 18.6 ± 8.9 (mild depression) post-treatment. Mean percent improvement was 34.5 % ± 21.1 from baseline to post-treatment. Paired sample t-test showed significant MADRS score decrease pre- to post-treatment [t(20) = 7.212, p < .001]. Overall, four (4) patients (19.0 %) responded and two (2) of those achieved remission (9.5 %).
Limitations of this case series include its retrospective and uncontrolled open-label nature, the lack of self-rating and standardized adverse events questionnaires, as well as follow-ups beyond the immediate treatment period.
Novel ways to increase the clinical effects of ketamine are being explored. We discuss potential combination approaches of ketamine with other modalities to augment its effects. Given the global burden of TRD, novel approaches are needed to curb the current mental health epidemic around the world.

BACKGROUND: Progress towards understanding the aetiology of major depression is compromised by its clinical heterogeneity. The variety of contexts underlying the development of a major depressive episode may contribute to such heterogeneity.
OBJECTIVE: To compare risk factor profiles for three subgroups of major depression according to episode context.
METHODS: Using self-report questionnaires and administrative records from the UK Biobank, we characterised three contextual subgroups of major depression: postpartum depression (3581 cases), depression following diagnosis of a chronic disease (409 cases) and a more typical (named heterogeneous) major depression phenotype excluding the two other contexts (34 699 cases). Controls with the same exposure were also defined. We tested each subgroup for association with the polygenic risk scores (PRS) for major depression and with other risk factors previously associated with major depression (bipolar disorder PRS, neuroticism, reported trauma in childhood and adulthood, socioeconomic status, family history of depression, education).
RESULTS: Major depression PRS was associated with all subgroups, but postpartum depression cases had higher PRS than heterogeneous major depression cases (OR = 1.06, 95% CI 1.02-1.10). Relative to heterogeneous depression, postpartum depression was more weakly associated with adulthood trauma and neuroticism. Depression following diagnosis of a chronic disease had weaker association with neuroticism and reported trauma in adulthood and childhood relative to heterogeneous depression.
CONCLUSIONS: The observed differences in risk factor profiles according to the context of a major depressive episode help provide insight into the heterogeneity of depression. Future studies dissecting such heterogeneity could help reveal more refined aetiological insights.

This study addressed ongoing questions about the meaning of patients\' perceptions of change during treatment. The study used data from the Veterans Outcome Assessment survey for patients with a depressive disorder, without mental health comorbidities, treated in Department of Veterans Affairs general mental health clinics (n = 694). Perceived changes in problems/symptoms, other domains, and the quality of communication with providers were evaluated with items from the Experience of Care & Health Outcomes (ECHO) survey. Depressive symptoms were measured with the Patient Health Questionnaire-9 (PHQ-9). Linear regression models evaluated associations of perceived change at 3-months post-baseline with observed change in PHQ-9 scores, scores on other patient-reported outcome measures (PROMs), and ratings of communication with providers. Patients\' reports of their clinical condition at follow-up together with ratings of communication accounted for approximately one-third of the variance in patients\' perceptions of change. Adding change-scores based on baseline and follow-up scores on the PHQ-9 and other PROMs did not improve model fit. The findings suggest that patient reports of perceived change during treatment reflect their current clinical state and their experience of care more closely than actual changes in the PHQ-9 or other PROMs.

Despite extensive evidence for its effectiveness, electroconvulsive therapy remains the subject of fierce opposition from those contesting its benefits and claiming extreme harms. Alongside some reflections on my experiences of this treatment, I examine the case against electroconvulsive therapy and find that it appears to rest primarily on unsubstantiated claims about major ethical violations, rather than clinical factors such as effectiveness and risk.

Treatment-resistant depression is a complex condition often requiring specialist psychiatric care. Many different psychiatric, physical and social factors can lead to a poor response to initial treatment of depression, and a careful assessment is required to determine the most appropriate management option. This can be particularly complex in the older population, who often have multiple physical and social comorbidities. We have used a fictional case to illustrate this, alongside an anonymised vignette of someone with personal experience of this condition. We have also provided an overview of the current evidence for treatment options, as well as a discussion of potential aetiological factors. By the end of this article, readers should understand the ambiguity of this diagnostic term, the aetiological factors that need to be assessed and the rationale for the treatment options available. They should be able to recognise how these ideas apply to the geriatric population.

Depressive disorders in adolescence are among the most challenging clinical syndromes to diagnostically identify and treat in psychotherapy. The Psychodynamic Diagnostic Manual, Second Edition (PDM-2) proposes an integration between nomothetic knowledge and an idiographic understanding of adolescent patients suffering from depression to promote a person-centered approach. This single-case study was aimed at describing and discussing the clinical value of an accurate diagnostic assessment within the PDM-2 framework.
Albert, a 16-year-old adolescent with a DSM-5 diagnosis of major depressive disorder, was assessed using instruments from various perspectives: the Structured Clinical Interview for DSM-5; the Psychodynamic Chart-Adolescent of the PDM-2, and other clinician-report instruments; and the Shedler-Westen Assessment Procedure for Adolescents and Defense Mechanisms Rating Scale Q-sort, coded by external observers.
Albert\'s assessment revealed impairments in various mental capacities, especially in regulating self-esteem. He presented a borderline personality organization at a high level and an emerging narcissistic personality syndrome.
The case discussion showed the importance of providing clinically meaningful assessments to plan for effective treatments in youth populations. Especially, it is necessary to understand the adolescent\'s unique characteristics in terms of mental and personality functioning and consider the developmental trajectories and adaptation processes that characterize this specific developmental period.

BACKGROUND: Questions have been raised regarding differences in the standards of care that patients receive when they are admitted to or discharged from in-patient units at weekends.
OBJECTIVE: To compare the quality of care received by patients with anxiety and depressive disorders who were admitted to or discharged from psychiatric hospital at weekends with those admitted or discharged during the \'working week\'.
METHODS: Retrospective case-note review of 3795 admissions to in-patient psychiatric wards in England. Quality of care received by people with depressive or anxiety disorders was compared using multivariable regression analyses.
RESULTS: In total, 795 (20.9%) patients were admitted at weekends and 157 (4.8%) were discharged at weekends. There were minimal differences in quality of care between those admitted at weekends and those admitted during the week. Patients discharged at weekends were less likely to be given sufficient notification (48 h) in advance of being discharged (OR = 0.55, 95% CI 0.39-0.78), to have a crisis plan in place (OR = 0.65, 95% CI 0.46-0.92) or to be given medication to take home (OR = 0.45, 95% CI 0.30-0.66). They were also less likely to have been assessed using a validated outcome measure (OR = 0.70, 95% CI 0.50-0.97).
CONCLUSIONS: There is no evidence of a \'weekend effect\' for patients admitted to psychiatric hospital at weekends, but the quality of care offered to those who were discharged at weekends was relatively poor, highlighting the need for improvement in this area.

Overweight/obesity and depression are common among women especially in the elderly and can lead to unfavorable outcomes. We aimed to determine the association of overweight with depression and also to find any correlation of depression with some anthropometric indices in old women. A total of 94 depressed elderly women were compared with 99 non-depressed controls. The structured diagnostic interview based on DSM-IV were performed to diagnose depression, and Geriatric Depression Scale (GDS) was completed to rate it. Anthropometric indices were measured and compared between groups. Pearson correlation coefficients were determined for linear relations between variables. Odds Ratio of obesity and overweight in depressed subjects comparing with normal participants was 1.45 (95%CI=0.63-3.32). A significant correlation was observed between BMI and GDS score (r=0.231, P-value=0.001). Total body fat (P-value=0.001) and BMI (P-value=0.016) were significantly higher in depressed women than non-depressed women. Despite the significantly higher total body fat and BMI among old women with depression, only a weak correlation was seen between BMI and GDS score.

Cotard\'s syndrome is a relatively rare condition that involves a delusion of negation in which an individual believes he or she has lost his or her soul, is dead, or is without functional body systems. This syndrome is observed in various neuropsychiatric disorders but most commonly in mood disorders. Pramipexole has often been used in the adjunctive treatment of both bipolar and unipolar depression, and it is known to cause rare but serious adverse effects such as compulsive behaviours in the treatment of Parkinson\'s disease. Here we report a case of Cotard\'s syndrome in treatment-resistant major depression associated with abnormal behaviours that might be caused by pramipexole. In the present case, the patient\'s abnormal behaviours gradually disappeared about 2 months after the discontinuation of pramipexole. The hypoperfusion in the bilateral parieto-occipital lobe found on single-photon emission computed tomography suggests the presence of Lewy body disease pathology. Nonetheless, the patient\'s abnormal behaviours disappeared after the discontinuation of pramipexole, indicating that they are mainly attributable to pramipexole treatment. However, the possible existence of Lewy body pathology could facilitate the emergence of abnormal behaviours after treatment with pramipexole. The patient\'s abnormal behaviours, such as eating other patients\' food and taking her medicine before the scheduled time, might differ from typical compulsive behaviours induced by pramipexole (such as pathological gambling and hypersexuality), but they could be regarded as disinhibition. Therefore, we should follow up on the clinical course of this case carefully through neuroimaging investigation and neurocognitive assessment.

This paper focuses on the relationship between depressive disorders, personality configurations, and mental functioning. A one-year treatment of a young man with the diagnosis of Depression is presented: the clinical and empirical points of view are described in depth through an assessment at the beginning and at one year after of an oriented psychodynamic psychotherapy. SCID I and II and HAMRS were administered to the patient in assessment phase. In the same phase he filled in BDI-II, and DEQ; the psychotherapist completed SWAP-200. These clinician instruments were used again after 1 year of the treatment. The PDM point of view is also presented. All sessions are audiotaped: 12 verbatim transcripts were coded with the Defense Mechanisms Rating Scale and CCRT. The results show a decrease in depressive symptoms, a change in some personality configurations, but a substantial invariance of the introjective profile, and a modification in mental functioning.
