RESUMEN

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has resulted in significant upheaval in psychiatric care. Despite survey data collected from psychiatric patients and broad samples of individuals in single countries, there is little quantitative or qualitative data on changes to psychiatric care from the perspective of mental health providers themselves across developing countries. METHODS: To address this gap, we surveyed 27 practicing psychiatrists from Central and Eastern Europe, as well as Africa, the Middle East, and Latin America. RESULTS: Respondents observed a marked increase in anxiety in their patients, with increased (though less prominent) symptoms of depression, somatization, and addiction. They reported largescale changes in the structure of psychiatric treatment, chiefly a decline in psychiatric admissions and closing/repurposing of psychiatric beds. Results supported strong "buy in" from clinicians regarding the use of telehealth, though some clinicians perceived a reduction in the ability to connect with, and build alliances with, their patients. Finally, clinicians described an improvement in the image and meaning of psychiatry in society, increased awareness of mental illness, and greater value placed on mental health in the general population. CONCLUSIONS: These changes warrant further empirical study as to their potential long-term ramifications, particularly as the COVID-19 pandemic persists and new waves of infection occur periodically throughout the world. The increased psychiatric burden on the population coupled with the apparent salience of mental health and well-being in the public consciousness represents a global opportunity for psychiatry to advocate for further treatment, research, and education.

RESUMEN

Importance: Apathy is prevalent among individuals with late-life depression and is associated with poor response to pharmacotherapy, including chronicity and disability. Elucidating brain networks associated with apathy and poor treatment outcomes can inform intervention development. Objectives: To assess the brain network features of apathy among individuals with late-life depression and identify brain network abnormalities associated with poor antidepressant response. Design, Setting, and Participants: This secondary analysis of a single-group, open-label nonrandomized clinical trial of escitalopram conducted at an outpatient geriatric psychiatry clinic enrolled 40 adults aged 59 to 85 years with major depressive disorder from July 1, 2012, to July 31, 2019. Interventions: After a 2-week washout period, participants received escitalopram titrated to a target of 20 mg/d for 12 weeks. Main Outcomes and Measures: Baseline and posttreatment magnetic resonance imaging (MRI), clinical, and cognitive assessments were conducted. Functional MRI was used to map group differences in resting state functional connectivity (rsFC) of the salience network, and diffusion MRI connectometry was performed to evaluate pathway-level disruptions in structural connectivity. The Apathy Evaluation Scale was used to quantify apathy, and the Hamilton Depression Rating Scale (HAM-D) was used to quantify the primary outcome of depression severity. Results: Forty participants (26 women [65%]; mean [SD] age, 70.0 [6.6] years [range, 59-85 years]) with depression were included; 20 participants (50%) also had apathy. Relative to nonapathetic participants with depression, those with depression and apathy had lower rsFC of salience network seeds with the dorsolateral prefrontal cortex (DLPFC), premotor cortex, midcingulate cortex, and paracentral lobule and greater rsFC with the lateral temporal cortex and temporal pole (z score >2.7; Bonferroni-corrected threshold of P < .0125). Compared with participants without apathy, those with apathy had lower structural connectivity in the splenium, cingulum, and fronto-occipital fasciculus (t score >2.5; false discovery rate-corrected P = .02). Twenty-seven participants completed escitalopram treatment; 16 (59%) achieved remission (HAM-D score <10). Lower insula-DLPFC/midcingulate cortex rsFC was associated with less symptomatic improvement (HAM-D % change) (ß [df] = 0.588 [26]; P = .001) and a higher likelihood of nonremission (odds ratio, 1.041 [95% CI, 1.003-1.081]; P = .04) after treatment and, in regression models, was a mediator of the association between baseline apathy and persistence of depression. Lower dorsal anterior cingulate-DLPFC/paracentral rsFC was associated with residual cognitive difficulties on measures of attention (ß [df] = 0.445 [26]; P = .04) and executive function (ß [df] = 0.384 [26]; P = .04). Conclusions and Relevance: This study suggests that disturbances in connectivity between the salience network and other large-scale networks that support goal-directed behavior may give rise to apathy and may be associated with poor response of late-life depression to antidepressant pharmacotherapy. These network disturbances may serve as targets for novel interventions. Trial Registration: ClinicalTrials.gov Identifier: NCT01728194.

RESUMEN

Tamoxifen is a synthetic, nonsteroidal antiestrogen widely used in the treatment of hormone-sensitive breast cancer that has also been shown to inhibit the enzyme protein kinase C (PKC). Upregulation of PKC is associated with disruption of prefrontal cortical regulation of thinking and behavior, which can lead to mania-like symptoms in animal models. Lithium and valproate, 2 mood stabilizers that are widely used in the treatment of bipolar disorder, have also been shown to inhibit PKC. We describe the case of a 48-year-old woman who entered a hypomanic state after discontinuation of tamoxifen while remaining on unopposed venlafaxine prescribed for depression. This case highlights the risk of misdiagnosing unipolar depression in breast cancer patients with undiagnosed bipolar disorder who are being treated with tamoxifen and subsequently started on antidepressants. The use of antidepressants in this population should be carefully monitored to avoid the development of manic, hypomanic, or mixed symptoms in patients with underlying bipolar disorder once tamoxifen is discontinued.

RESUMEN

Less than 40% of depressed older adults treated with an antidepressant achieve remission. Incomplete response to treatment is common. Current augmentation strategies have limited efficacy, and many have side effects that restrict their utilization in older adults. We conducted the first open pilot trial of minocycline augmentation in older adults who had failed to achieve remission after adequate psychopharmacologic treatment. Subjects older than 55 years of age with major depression and failure to achieve substantial improvement of depressive symptoms after at least 6 weeks of antidepressant treatment were given augmentation with minocycline 100 mg twice daily over an 8-week period. At the end of 8 weeks of augmentation with minocycline, 31% (4/13) patients achieved remission. Remitters had higher baseline ratings of hopelessness and apathy. Minocycline was well tolerated with no reported adverse events or discontinuation due to intolerance. Larger placebo-controlled studies are needed to evaluate the effects of minocycline augmentation in older adults who had failed to achieve remission after adequate treatment with antidepressants.

RESUMEN

OBJECTIVE: Poststroke depression (PSD) has a heterogeneous presentation and is often accompanied by cognitive impairment. This study aimed to identify distinct dimensions of depressive symptoms in older adults with PSD and to evaluate their relationship to cognitive functioning. DESIGN: Cross-sectional factor and correlational analyses of patients with poststroke depression. SETTING: Patients were recruited from the community and from acute inpatient stroke rehabilitation hospitals. PARTICIPANTS: Participants had suffered a stroke and met DSM-IV criteria for major depression (≥18 Montgomery Åsberg Depression Scale; MADRS). INTERVENTION: None. MEASUREMENTS: MADRS was used to quantify depression severity at study entry. Neuropsychological assessment at the time of study entry consisted of measures of Global Cognition, Attention, Executive Function, Processing Speed, Immediate Memory, Delayed Memory, and Language. RESULTS: There were 135 (age ≥50) older adult participants with PSD and varying degrees of cognitive impairment (MMSE Total ≥20). Factor analysis of the MADRS identified three factors, that is sadness, distress, and apathy. Items comprising each factor were totaled and correlated with neuropsychological domain z-score averages. Symptoms of the apathy factor (lassitude, inability to feel) were significantly associated with greater impairment in executive function, memory, and global cognition. Symptoms of the sadness and distress factors had no relationship to cognitive impairment. CONCLUSION: PSD consists of three correlated dimensions of depressive symptoms. Apathy symptoms are associated with cognitive impairment across several neuropsychological domains. PSD patients with prominent apathy may benefit from careful attention to cognitive functions and by interventions that address both psychopathology and behavioral deficits resulting from cognitive impairment.

RESUMEN

BACKGROUND: Negative self-referential thinking is a common symptom of depression associated with poor treatment response. In late-life depression, white matter abnormalities may contribute to negative self-referential thoughts following antidepressant treatment. We investigated the association of fractional anisotropy (FA) in select regions of the negative valence system (NVS) with residual negative self-referential thoughts following treatment with escitalopram for late-life depression. METHODS: The participants were older adults with major depression and psychiatrically normal controls. Depressed participants received 12 weeks of treatment with escitalopram. To assess self-referential thinking, participants completed a Trait Adjective Task at baseline and at week 12. Baseline MRI scans included a diffusion imaging sequence for FA analyses. RESULTS: Participants with late-life depression differed from controls on all performance measures of the Trait Adjective Task at baseline and at 12 weeks. Depressed participants endorsed fewer negative personality traits and more positive personality traits at week 12 compared to baseline. Lower FA in the dorsal anterior cingulate and in the uncinate fasciculus in depressed participants was correlated with residual negative self-referential thinking (e.g., more endorsed negative adjectives, fewer rejected negative adjectives) at treatment end. LIMITATIONS: The sample size is modest so the findings are preliminary. FA analyses were restricted to predetermined regions. CONCLUSIONS: Negative self-referential thinking improved in depressed older adults following 12 weeks of treatment with escitalopram. Baseline FA in select white matter regions of the NVS was associated with residual negative self-referential thinking. These findings may help identify treatment targets for residual negative self-referential thoughts.

RESUMEN

Depression worsens most treatment outcomes in medically ill older adults. Chronic medical illnesses weaken and demoralize patients and compromise their ability to adhere to treatments requiring consistency and effort. Acute medical illnesses create a psychosocial storm that finds patients and their ecosystem unprepared. We describe two intervention models that can be used to target and personalize treatment in depressed, chronically, or acutely medically ill older adults. The Personalized Adherence Intervention for Depression and COPD (PID-C) is a model intervention for depressed patients with chronic medical illnesses. It targets patient-specific barriers to treatment engagement and aims to shift the balance in favor of treatment participation. PID-C led to higher remission rates of depression, reduction in depressive symptoms, and reduction in dyspnea-related disability. The addition of problem-solving training enables patients to use resources available to them and hopefully improve their outcomes. Ecosystem-focused therapy (EFT) is a model intervention for depression developing in the context of an acute medical event. It was developed for patients with poststroke depression (PSD) and targets five areas, part of the "psychosocial storm" originating from the patient's sudden disability and the resulting change in the patient's needs and family's life. A preliminary study suggests that EFT is feasible and efficacious in reducing depressive symptoms and signs and disability in PSD.

RESUMEN

Antiphospholipidsyndrome (APS) is an autoimmune disorder which causes a hyper-coagulable state characterized by recurrent thrombosis. It has a diverse range of central nervous system manifestations. We describe a case of a 61 year old man with bipolar disorder and APS, and we compare this to a previously reported case. Additionally, we reviewed literature regarding APS-related markers and the relationship of APS to other psychiatric and neurologic illnesses. We discuss possible mechanisms for an association between APS and bipolar disorder. We encourage clinicians to be aware of this possible relationship and have proposed research strategies.
