Purpose: Existing literature describes the interdependence between neurotrophic and vascular signals in the central nervous system. We hypothesize a similar crosstalk important to extremity healing involving the peripheral nervous system and angiogenic cells. Nerves are difficult to capture via axons found in the periphery alone. Thus, we have interrogated from publicly available single-nuclei transcriptomic data of peripheral nerve soma (dorsal root ganglia), injured by physical transection or chemically induced pain. We present a combined analysis of extremity polytrauma (burn/tenotomy HO model) and peripheral nerve (post-injury/pain DRG model) to determine if there is expression of vascular signals by nerves and reciprocal neurotrophic signals by cells local to the injury site. Methods: A 30% dorsal burn and Achilles transection was performed in C57/BL6J mice. The tendon site tissues were harvested from baseline (t0) and day 7, 42 after induction. Samples were prepared for library generation on a 10x Genomics Chromium Controller, sequenced on a Illumina HiSeq 4000, and analyzed with Cell Ranger Software for pre-processing and alignment to the mm10 genome. DRG analyses and clusters were abstracted from NIH-GEO (GSE154659). Downstream analyses including unsupervised clustering downstream analyses were performed with Seurat. Results: We first examined candidate neurotrophins and vascular signals in nerve (DRG), finding robust upregulation of Bdnf and Vegfa. In HO, the site of injury contains many cells that may potentially respond to these signals. Indeed, in sequencing data from the pre-HO anlagen, endothelium and smooth muscle cell populations express upregulation for receptors to the nerve-derived Vegfa via Flt1/VEGFR1. This population in addition to being sensitive to the VEGFA ligand, also demonstrates upregulation of Ngf, signifying a potential vasculo-neuro axis where a vascular signal induces endothelium/SMCs to produce neurotrophic signals. Completing the circuit, the original DRG cells and by logical extension, regenerating peripheral nerves, are highly enriched for the neurotrophin receptors: Ntrk1/TrkA (responsive to the SMC derived NGF), Ntrk2/TrkB (responsive to the nerve-autonomous BDNF), and Ntrk3/TrkC (partial combined NGF/BDNF response). This potentially signifies a feedforward loop where peripheral nerve induces angiogenesis which in return, promotes nascent nerve ingrowth in a cyclical process. Indeed, in targeted knockout of a local VEGFA source (VegfaPrrx1 mice), the injury site demonstrates parallel reduction in vascular density (77%) and reduction in nerve fiber frequency (62%) within the HO site. Conclusions: These findings represent the first work characterizing the coordination between neurogenic and angiogenic transcription programs following extremity trauma. We demonstrate through NextGen sequencing, evidence of neuroangiogenic crosstalk following musculoskeletal/neural injury. This VEGFA/NGF axis involves vascular signaling as a potential source for additional proliferation of NGF expressing pericyte/SMCs. The presented data describe the potential nerve-driven regulation contributing to the formation of HO at the extremity that with antagonism or inhibition may lead to better treatments for aberrant extremity wound healing.

Purpose: It is controversial whether subsidence after trapeziectomy prognosticates pain, poor outcomes, and need for revision. The aim of this study was to investigate the degree of subsidence following trapeziectomy and whether subsidence contributes to poor outcomes. Methods: An IRB approved retrospective review of all patients who underwent trapeziectomy for osteoarthritis of the first carpometacarpal (CMC) joint was conducted from 2003 to 2019. Patients with available radiographic imaging greater than three months postoperatively were included. Patients with arthritis of the metacarpophalangeal joint of the thumb, arthritis of radiocarpal, distal radioulnar, and midcarpal joints were excluded. Demographic information, pain scores, and revision procedures were recorded. Conolly-Rath patient function scores were determined. Subsidence was measured by the ratio of the difference between the trapezial space (TS = distance from base of thumb metacarpal to scaphoid) preoperatively and TS postoperatively over the TS preoperatively. Patients were divided as having a high degree of subsidence (≥50%) or low degree of subsidence (

Objective: The authors hypothesized that the depression treatment preferences of elderly home care patients would vary by their experience of depression and that preferences for active treatment would be associated with current depression and with antidepressant treatment.Methods: The authors conducted cross-sectional secondary analyses of data from the TRIAD study (Training in the Assessment of Depression) of 256 randomly selected elderly patients newly admitted to home care. The study assessed preference for active treatments (medication or psychotherapy) and nonactive or complementary approaches (such as religious activities or doing nothing). Nondepressed patients were asked to choose as if they had serious depression. Two separate indicators of depression experience were used: a current diagnosis of major or minor depression and current or previous antidepressant treatment.Results: Of the 256 patients, 16% (N=41) met criteria for major or minor depression. Forty-seven percent of the sample (N=121) preferred an active treatment as their first choice, and others preferred nonactive or complementary approaches. Logistic regression indicated that current antidepressant use, previous psychotherapy experience, white or Hispanic race-ethnicity (versus black), greater impairment in instrumental activities of daily living, and less personal stigma about depression were independently associated with preference for an active treatment.Conclusions: Elderly home care patients had a variety of treatment preferences, ranging from active treatments, to religious or spiritual activities, to no treatment. Several factors were associated with a preference for active treatment, including treatment experience, physical impairment, race-ethnicity, and attitudes and beliefs. An understanding of patient preferences may help engage older depressed home care patients in treatment. [ABSTRACT FROM AUTHOR]

Objective: To compare the frequency of anxiety disorders in older and younger persons with major depressive disorder with psychotic features.Design: Cross-sectional.Setting: University medical centers.Participants: Two hundred fifty-nine persons (N = 117 aged 18-59 years and N = 142 aged > or =60 years) with major depressive disorder with psychotic features who were enrolled in the Study of the Pharmacotherapy of Psychotic Depression (STOP-PD).Measurements: Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, (DSM-IV) defined anxiety disorders were determined by Structured Clinical Interview for DSM-IV interview at baseline assessment. Younger and older participants were compared on the frequencies of any current anxiety disorder and any lifetime anxiety disorder, as well as the frequencies of individual anxiety disorders.Results: Older persons had significantly lower frequencies of any current anxiety disorder and any lifetime anxiety disorder, even after controlling for relevant demographic and clinical variables. With respect to specific anxiety disorders, older persons had significantly lower frequencies of current and lifetime panic disorder, current and lifetime social anxiety disorder, and current and lifetime posttraumatic stress disorder.Conclusion: The findings of this study are consistent with those of community-based epidemiologic surveys that anxiety disorders are less prevalent in older than younger adults. Because of the rigorous assessment used in STOP-PD, our findings suggest that the age-related decline in the prevalence of anxiety disorders is not simply due to a failure to detect cases in older people, as has been previously suggested.

OBJECTIVE: To assess the completeness and accuracy of clinical information provided by referral sources to visiting nurses for patients admitted to receive home health care. METHODS: Clinical referral information for a representative sample of 243 older adults admitted to receive skilled home-health nursing was compared to medical record information from home-health charts and in-home research interviews to determine their concordance. Measures used included referral information, home-care chart documentation, in-home nurse review of medications, medication allergies, caregiver contact information, cognitive status, depression status, and follow-up plan. RESULTS: There were medication discrepancies between in-home nurse review and admission information in 215 cases (88.4%). Clinical information on medication allergies was lacking from referrers in 85 cases (34.9%). No information was provided by the referrers about cognitive status in 38 (73%) cases classified as cognitively impaired and in only 2 of 35 cases with major depression identified with the Structured Clinical Interview for Axis I Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID), was depression related information provided by referrers. CONCLUSIONS: The primary finding of this study is that during a transfer of an older adult to the home care service sector, essential clinical information is often missing, and there are significant discrepancies between medication regimens. These findings support the need for both educational initiatives and technology to address the complex care needs of older adults across settings to reduce the risk for medication errors and poor outcomes.

Objective: To reexamine the conclusions of the 1991 National Institutes of Health Consensus Panel on Diagnosis and Treatment of Depression in Late Life in light of current scientific evidence.Participants: Participants included National Institutes of Health staff and experts drawn from the Planning Committee and presenters of the 1991 Consensus Development Conference.Evidence: Participants summarized relevant data from the world scientific literature on the original questions posed for the conference.Process: Participants reviewed the original consensus statement and identified areas for update. The list of issues was circulated to all participants and amended to reflect group agreement. Selected participants prepared first drafts of the consensus update for each issue. All drafts were read by all participants and were amended and edited to reflect group consensus.Conclusions: The review concluded that, although the initial consensus statement still holds, there is important new information in a number of areas. These areas include the onset and course of late-life depression; comorbidity and disability; sex and hormonal issues; newer medications, psychotherapies, and approaches to long-term treatment; impact of depression on health services and health care resource use; late-life depression as a risk factor for suicide; and the importance of the heterogeneous forms of depression. Depression in older people remains a significant public health problem. The burden of unrecognized or inadequately treated depression is substantial. Efficacious treatments are available. Aggressive approaches to recognition, diagnosis, and treatment are warranted to minimize suffering, improve overall functioning and quality of life, and limit inappropriate use of health care resources.

Little is known about factors that contribute to attrition in clinical trials of the pharmacotherapy of psychotic depression. The purpose of this study was to identify factors associated with attrition during acute pharmacotherapy in the Study of the Pharmacotherapy of Psychotic Depression II (STOP-PD II) clinical trial. Sociodemographic and clinical variables were assessed at baseline in 269 men and women, aged 18-85 years, who were treated with up to 12 weeks of open-label sertraline plus olanzapine. Univariate analyses examined the association of baseline variables with overall non-completion, as well as reasons for non-completion. Logistic regression was used to model the relationship of the significant univariate predictors with non-completion and its reasons. Seventy-four (27.5 %) participants did not complete the acute treatment phase of STOP-PD II. Male gender, younger age, inpatient status, higher Clinical Global Impression (CGI) severity of illness, and higher severity of psychomotor disturbance were associated with non-completion in univariate analyses. In regression models, higher CGI severity of illness score was the only significant independent predictor of non-completion, explained by withdrawal of consent. Our findings have implications for the retention of persons with psychotic depression in clinical trials., Competing Interests: Declaration of competing interest R. A.

Background: Remitted psychotic depression (MDDPsy) has heterogeneity of outcome. The study's aims were to identify subgroups of persons with remitted MDDPsy with distinct trajectories of depression severity during continuation treatment and to detect predictors of membership to the worsening trajectory., Method: One hundred and twenty-six persons aged 18-85 years participated in a 36-week randomized placebo-controlled trial (RCT) that examined the clinical effects of continuing olanzapine once an episode of MDDPsy had remitted with sertraline plus olanzapine. Latent class mixed modeling was used to identify subgroups of participants with distinct trajectories of depression severity during the RCT. Machine learning was used to predict membership to the trajectories based on participant pre-trajectory characteristics., Results: Seventy-one (56.3%) participants belonged to a subgroup with a stable trajectory of depression scores and 55 (43.7%) belonged to a subgroup with a worsening trajectory. A random forest model with high prediction accuracy (AUC of 0.812) found that the strongest predictors of membership to the worsening subgroup were residual depression symptoms at onset of remission, followed by anxiety score at RCT baseline and age of onset of the first lifetime depressive episode. In a logistic regression model that examined depression score at onset of remission as the only predictor variable, the AUC (0.778) was close to that of the machine learning model., Conclusions: Residual depression at onset of remission has high accuracy in predicting membership to worsening outcome of remitted MDDPsy. Research is needed to determine how best to optimize the outcome of psychotic MDDPsy with residual symptoms.

Background: The neurobiology of psychotic depression is not well understood and can be confounded by antipsychotics. Magnetic resonance spectroscopy (MRS) is an ideal tool to measure brain metabolites non-invasively. We cross-sectionally assessed brain metabolites in patients with remitted psychotic depression and controls. We also longitudinally assessed the effects of olanzapine versus placebo on brain metabolites., Methods: Following remission, patients with psychotic depression were randomized to continue sertraline + olanzapine (n = 15) or switched to sertraline + placebo (n = 18), at which point they completed an MRS scan. Patients completed a second scan either 36 weeks later, relapse, or discontinuation. Where water-scaled metabolite levels were obtained and a Point-RESolved Spectroscopy sequence was utilized, choline, myo-inositol, glutamate + glutamine (Glx), N-acetylaspartate, and creatine were measured in the left dorsolateral prefrontal cortex (L-DLPFC) and dorsal anterior cingulate cortex (dACC). An ANCOVA was used to compare metabolites between patients (n = 40) and controls (n = 46). A linear mixed-model was used to compare olanzapine versus placebo groups., Results: Cross-sectionally, patients (compared to controls) had higher myo-inositol (standardized mean difference [SMD] = 0.84; 95%CI = 0.25-1.44; p = 0.005) in the dACC but not different Glx, choline, N-acetylaspartate, and creatine. Longitudinally, patients randomized to placebo (compared to olanzapine) showed a significantly greater change with a reduction of creatine (SMD = 1.51; 95%CI = 0.71-2.31; p = 0.0002) in the dACC but not glutamate + glutamine, choline, myo-inositol, and N-acetylaspartate., Conclusions: Patients with remitted psychotic depression have higher myo-inositol than controls. Olanzapine may maintain creatine levels. Future studies are needed to further disentangle the mechanisms of action of olanzapine., (© 2023. The Author(s).)

The effect of antipsychotic medication on resting state functional connectivity in major depressive disorder (MDD) is currently unknown. To address this gap, we examined patients with MDD with psychotic features (MDDPsy) participating in the Study of the Pharmacotherapy of Psychotic Depression II. All participants were treated with sertraline plus olanzapine and were subsequently randomized to continue sertraline plus olanzapine or be switched to sertraline plus placebo. Participants completed an MRI at randomization and at study endpoint (study completion at Week 36, relapse, or early termination). The primary outcome was change in functional connectivity measured within and between specified networks and the rest of the brain. The secondary outcome was change in network topology measured by graph metrics. Eighty-eight participants completed a baseline scan; 73 completed a follow-up scan, of which 58 were usable for analyses. There was a significant treatment X time interaction for functional connectivity between the secondary visual network and rest of the brain (t = -3.684; p = 0.0004; pFDR = 0.0111). There was no significant treatment X time interaction for graph metrics. Overall, functional connectivity between the secondary visual network and the rest of the brain did not change in participants who stayed on olanzapine but decreased in those switched to placebo. There were no differences in changes in network topology measures when patients stayed on olanzapine or switched to placebo. This suggests that olanzapine may stabilize functional connectivity, particularly between the secondary visual network and the rest of the brain., (© 2023.

Background: Psychomotor disturbance is common in psychotic depression and is associated with relapse. In this analysis, we examined whether white matter microstructure is associated with relapse probability in psychotic depression and, if so, whether white matter microstructure accounts for the association between psychomotor disturbance and relapse., Methods: We used tractography to characterize diffusion-weighted MRI data in 80 participants enrolled in a randomized clinical trial that compared efficacy and tolerability of sertraline plus olanzapine with sertraline plus placebo in the continuation treatment of remitted psychotic depression. Cox proportional hazard models tested the relationships between psychomotor disturbance (processing speed and CORE score) at baseline, white matter microstructure (fractional anisotropy [FA] and mean diffusivity [MD]) in 15 selected tracts at baseline, and relapse probability., Results: CORE was significantly associated with relapse. Higher mean MD was significantly associated with relapse in the each of the following tracts: corpus callosum, left striato-frontal, left thalamo-frontal, and right thalamo-frontal. CORE and MD were each associated with relapse in the final models., Limitations: As a secondary analysis with a small sample size, this study was not powered for its aims, and is vulnerable to types I and II statistical errors. Further, the sample size was not sufficient to test the interaction of the independent variables and randomized treatment group with relapse probability., Conclusions: While both psychomotor disturbance and MD were associated with psychotic depression relapse, MD did not account for the relationship between psychomotor disturbance and relapse. The mechanism by which of psychomotor disturbance increases the risk of relapse requires further investigation., Clinical Trial Registration: Study of the Pharmacotherapy of Psychotic Depression II (STOP-PD II); NCT01427608.

Background: Impaired insight into delusions is associated with a lower probability of remission of psychotic depression, independent of illness severity. The relationship between participant characteristics and impaired insight into delusions in remitted psychotic depression, and whether impaired insight is associated with risk of relapse of psychotic depression during continuation pharmacotherapy were examined., Methods: Data were analyzed from 126 participants in the STOP-PD II study who experienced sustained remission of psychotic depression during 8-week stabilization treatment with sertraline plus olanzapine and were then randomized to 36 weeks of continuation treatment with sertraline plus either olanzapine or placebo. Insight into delusions was assessed with the Resolution of Delusions Scale (RODS). Linear regression analyses examined the associations between participant characteristics and insight into delusions. Cox proportional-hazards models examined whether i) change in RODS during stabilization treatment; or ii) RODS at the end of stabilization treatment predicted risk of relapse during 36 weeks of continuation treatment., Results: Severity of psychosis before initiation of treatment was the only participant characteristic associated with the change in insight during stabilization treatment. Neither change in insight during stabilization treatment nor insight at the end of stabilization treatment was associated with risk of relapse., Limitations: Insufficient statistical power and the lack of variability in RODS scores at the time of randomization may have contributed to the absence of a relationship between RODS and risk of relapse., Conclusion: Residual or reemergent insight impairment following acute treatment does not preclude patients from sustaining remission of psychotic depression in a randomized placebo-controlled trial., Competing Interests: Conflict of interest J.

Introduction: Little is known regarding genetic factors associated with treatment outcome of psychotic depression. We explored genomic associations of remission and relapse of psychotic depression treated with pharmacotherapy., Methods: Genomic analyses were performed in 171 men and women aged 18-85 years with an episode of psychotic depression who participated in the Study of the Pharmacotherapy of Psychotic Depression II (STOP-PD II). Participants were treated with open-label sertraline plus olanzapine for up to 12 weeks; those who achieved remission or near-remission and maintained it following 8 weeks of stabilization were eligible to participate in a 36-week randomized controlled trial that compared sertraline plus olanzapine with sertraline plus placebo in preventing relapse., Results: There were no genome-wide significant associations with either remission or relapse. However, at a suggestive threshold, SNP rs1026501 (31 kb from SYNPO2) in the whole sample and rs6844137 (within the intronic region of SYNPO2) in the European ancestry subsample were associated with a decreased likelihood of remission. In polygenic risk analyses, participants who had greater improvement after antidepressant treatments showed a higher likelihood of reaching remission. Those who achieved remission and had a higher polygenic risk for Alzheimer's disease had a significantly decreased likelihood of relapse., Conclusion: Our analyses provide preliminary insights into the genetic architecture of remission and relapse in a well-characterized group of patients with psychotic depression., (© 2023 The Author(s).

Psychotic depression has a high rate of relapse. The study aims were to identify a prediction model of risk of relapse of psychotic depression and examine whether predictors moderated the effect of treatment on relapse. One hundred and twenty-six men and women aged 18-85 years, who experienced sustained remission or near-remission of psychotic depression with sertraline plus olanzapine, participated in a 36-week randomized controlled trial that compared sertraline plus olanzapine with sertraline plus placebo in preventing relapse (NCT01427608). Cox regression analyses were performed to identify significant predictors of relapse and to model the combined role of significant predictors. Concordance statistic was calculated to determine the accuracy of the best fit multivariable models in predicting relapse. Finally, interaction terms were tested for each significant predictor to examine whether they moderated the effect of treatment on risk of relapse. Lifetime number of depressive episodes, severity of residual depressive symptoms at the time of randomization, and psychomotor disturbance both at acute enrollment when participants were depressed and at the time of randomization predicted risk of relapse. Multivariable models had 69-70% accuracy in predicting relapse. Psychomotor disturbance was associated with increased risk of relapse in the sertraline plus olanzapine group compared with sertraline plus placebo, whereas the other predictors did not moderate the effect of treatment on relapse. Future research is needed to determine whether a combination of clinical and biological variables can further increase the accuracy of prediction of relapse of psychotic depression., Competing Interests: Declaration of competing interest A.J.

Importance: Familial exudative vitreoretinopathy (FEVR) is a nonsyndromic autosomal dominant retinal disorder commonly caused by variants in the FZD4 gene. This study investigates the potential role beyond ocular abnormalities for FZD4 gene variants in patients with FEVR., Objective: To evaluate the role of FZD4 in symptoms beyond those associated with FEVR through a patient with biallelic variants in FZD4., Design, Setting, and Participants: This case series included the DNA testing and phenotyping of 1 patient proband and her parents, combined with signaling assays, to determine the association of patient-derived compound heterozygous variants on FZD4 signaling and biologic function., Main Outcomes and Measures: FZD4 genes were tested using next-generation sequencing and Sanger sequencing. Cell-based assays measured the effect of the variants on FZD4 signaling., Results: The proband presented with absent red reflexes from complete tractional retinal detachments diagnosed at 3 days of age and failed the newborn screening hearing test. Auditory brainstem response at 6 months of age showed bilateral mild to moderate high-frequency sensorineural hearing loss. The patient manifested developmental delays in speech and walking. Intravenous fluorescein angiography (IVFA) of the patient's parents detected stage 1 FEVR. Genetic testing revealed 2 FZD4 variants in the patient, each variant found in 1 parent. Signaling assays confirmed that the presence of both variants was associated with significantly worse signaling activity compared with the heterozygous state., Conclusions and Relevance: Results of this case series suggest that extraocular syndromic FEVR was associated with FZD4 variants. The decrease in FZD4 signaling owing to the biallelic nature of the disease resulted in hearing deficits, developmental delays, and a more severe retinal phenotype.

The CORE instrument is commonly used to measure psychomotor disturbance. We examined the factor structure of the CORE in 266 adults with an acute episode psychotic depression, a disorder with a high rate of psychomotor disturbance. Exploratory factor analysis identified a two-factor solution: Factor 1 corresponded to the CORE's retardation and non-interactiveness items and Factor 2 corresponded to its agitation items. Internal consistency was excellent for Factor 1 but questionable for Factor 2. These findings suggest that the CORE's retardation and non-interactiveness items should be combined in one subscale when assessing patients with an acute episode of psychotic depression., (Copyright © 2022.

Background: Over the past 2 decades there has been a substantial increase in the number of new cancer medicines; this has been accompanied by a dramatic rise in drug costs. It is unknown how these trends impact the revenue of the pharmaceutical sector., Methods: Retrospective cohort study to characterize temporal trends of revenue generated from cancer medicines as a proportion of total drug revenue among 10 large pharmaceutical companies from 2010 to 2019. Itemized product-sales data publicly available through company websites or annual filings were used to identify annual drug revenue. Revenue data were adjusted for inflation and converted to 2019 US dollars., Results: During the study period, cumulative annual revenue generated from cancer drugs increased by 70%: from $55.8 billion to $95.1 billion, while cumulative revenue from nononcology drugs decreased 18%: from $342.2 billion to $281.5 billion. The proportion of total drug revenue generated from oncology drugs increased substantially over the study period: from 14% in 2010 to 25% in 2019 (τ = 1.0, P < .001)., Conclusions: Among 10 of the world's largest pharmaceutical companies, revenues generated from the sale of cancer drugs have increased by 70% over the past decade, while revenues from other medicines have decreased by 18%. Revenues from cancer drugs now account for one-quarter of the net revenues from these companies. Further work is needed to understand if this increase in sales revenue reflects industry profit, and to what extent increased spending has translated into improvements in patient and population outcomes., (© 2021 American Cancer Society.)

Objective: To examine the effect of older versus younger age on change in anthropometric and metabolic measures during extended treatment of psychotic depression with sertraline plus olanzapine., Methods: Two hundred and sixty-nine men and women aged 18-85 years with an episode of psychotic depression were treated with open-label sertraline plus olanzapine for up to 12 weeks. Participants who remained in remission following an 8-week stabilization phase were eligible to participate in a 36-week randomized controlled trial (RCT) that compared the efficacy and tolerability of sertraline plus olanzapine with sertraline plus placebo. Weight, waist circumference and plasma lipids, glucose, HbA1c, and insulin were measured at regular intervals during the acute, stabilization and randomized phases of the study. Linear mixed models were used to analyze the trajectories of anthropometric and metabolic measures., Results: Participants aged 60 years or older experienced less weight gain and less increase in cholesterol during the combined acute and stabilization phases of the study compared with those aged 18-59 years. At the acute-stabilization termination visit, mean weight in older participants was 6.5 lb. less than premorbid weight, whereas it was 17.9 lb. more than premorbid weight in younger participants. In the RCT, there was a significant interaction of treatment and age group for the trajectory of weight, but the post hoc tests that compared age groups within each treatment arm were not statistically significant. There were no clinically significant differences between younger and older participants in glycemic measures., Conclusion: Older patients with psychotic depression experienced less increase in weight and total cholesterol than their younger counterparts during acute and stabilization treatment with sertraline plus olanzapine. In the older group, weight gained during the acute and stabilization phases appeared to be partial restoration of weight lost during the index episode of depression, whereas weight gain in younger participants was not., (Copyright © 2020 American Association for Geriatric Psychiatry.

Background: Little is known about the relationship between psychomotor disturbance (PMD) and treatment outcome of psychotic depression. This study examined the association between PMD and subsequent remission and relapse of treated psychotic depression., Methods: Two hundred and sixty-nine men and women aged 18-85 years with an episode of psychotic depression were treated with open-label sertraline plus olanzapine for up to 12 weeks. Participants who remained in remission or near-remission following an 8-week stabilization phase were eligible to participate in a 36-week randomized controlled trial (RCT) that compared the efficacy and tolerability of sertraline plus olanzapine (n = 64) with sertraline plus placebo (n = 62). PMD was measured with the psychiatrist-rated sign-based CORE at acute phase baseline and at RCT baseline. Spearman's correlations and logistic regression analyses were used to analyze the association between CORE total score at acute phase baseline and remission/near-remission and CORE total score at RCT baseline and relapse., Results: Higher CORE total score at acute phase baseline was associated with lower frequency of remission/near-remission. Higher CORE total score at RCT baseline was associated with higher frequency of relapse, in the RCT sample as a whole, as well as in each of the two randomized groups., Conclusions: PMD is associated with poorer outcome of psychotic depression treated with sertraline plus olanzapine. Future research needs to examine the neurobiology of PMD in psychotic depression in relation to treatment outcome.

Purpose/background: Electroconvulsive therapy (ECT) is effective in the treatment of acute episodes of psychotic depression. However, no adequately powered studies have directly investigated the efficacy of antipsychotic pharmacotherapy in relapse prevention of psychotic depression after ECT. In the absence of such literature, we reviewed the clinical practice of 4 academic medical centers that have made research contributions in the treatment of psychotic depression over the past 20 years., Methods/procedures: We reviewed medical records of patients with a diagnosis of psychotic depression who received 1 or more acute courses of ECT over the span of 3 years. Chi-square tests were used to compare pharmacotherapy prescribed at the time of completion of ECT., Findings/results: A total of 163 patients received 176 courses of ECT for separate episodes of psychotic depression. The combination of an antidepressant plus an antipsychotic was the most common regimen, ranging from 61.9% to 85.5% of all prescriptions. One center added lithium in 45.5% of cases treated with the combination of an antidepressant plus an antipsychotic. An antipsychotic alone was prescribed in less than 10% of cases. An antidepressant alone or other drug combinations were rare., Implications/conclusions: The combination of an antidepressant plus an antipsychotic was the most commonly prescribed regimen at the completion of ECT for relapse prevention in patients with psychotic depression acutely treated with ECT. Although this report offers a view of the clinical practice of 4 academic medical centers, it also points to the need of randomized controlled trials on continuation pharmacotherapy after treatment of psychotic depression with ECT., (Copyright © 2021 Wolters Kluwer Health, Inc.

Importance: Prescriptions for antipsychotic medications continue to increase across many brain disorders, including off-label use in children and elderly individuals. Concerning animal and uncontrolled human data suggest antipsychotics are associated with change in brain structure, but to our knowledge, there are no controlled human studies that have yet addressed this question., Objective: To assess the effects of antipsychotics on brain structure in humans., Design, Setting, and Participants: Prespecified secondary analysis of a double-blind, randomized, placebo-controlled trial over a 36-week period at 5 academic centers. All participants, aged 18 to 85 years, were recruited from the multicenter Study of the Pharmacotherapy of Psychotic Depression II (STOP-PD II). All participants had major depressive disorder with psychotic features (psychotic depression) and were prescribed olanzapine and sertraline for a period of 12 to 20 weeks, which included 8 weeks of remission of psychosis and remission/near remission of depression. Participants were then were randomized to continue receiving this regimen or to be switched to placebo and sertraline for a subsequent 36-week period. Data were analyzed between October 2018 and February 2019., Interventions: Those who consented to the imaging study completed a magnetic resonance imaging (MRI) scan at the time of randomization and a second MRI scan at the end of the 36-week period or at time of relapse., Main Outcomes and Measures: The primary outcome measure was cortical thickness in gray matter and the secondary outcome measure was microstructural integrity of white matter., Results: Eighty-eight participants (age range, 18-85 years) completed a baseline scan; 75 completed a follow-up scan, of which 72 (32 men and 40 women) were useable for final analyses. There was a significant treatment-group by time interaction in cortical thickness (left, t = 3.3; P = .001; right, t = 3.6; P < .001) but not surface area. No significant interaction was found for fractional anisotropy, but one for mean diffusivity of the white matter skeleton was present (t = -2.6, P = .01). When the analysis was restricted to those who sustained remission, exposure to olanzapine compared with placebo was associated with significant decreases in cortical thickness in the left hemisphere (β [SE], 0.04 [0.009]; t34.4 = 4.7; P <.001), and the right hemisphere (β [SE], 0.03 [0.009]; t35.1 = 3.6; P <.001). Post hoc analyses showed that those who relapsed receiving placebo experienced decreases in cortical thickness compared with those who sustained remission., Conclusions and Relevance: In this secondary analysis of a randomized clinical trial, antipsychotic medication was shown to change brain structure. This information is important for prescribing in psychiatric conditions where alternatives are present. However, adverse effects of relapse on brain structure support antipsychotic treatment during active illness., Trial Registration: ClinicalTrials.gov Identifier: NCT01427608.

Major depressive disorder with psychotic features (psychotic depression) is a severe disorder. Compared with other psychotic disorders such as schizophrenia, relatively few studies on the neurobiology of psychotic depression have been pursued. Neuroimaging studies investigating psychotic depression have provided evidence for distributed structural brain abnormalities implicating the insular cortex and limbic system. We examined structural brain networks in participants (N = 245) using magnetic resonance imaging. This sample included healthy controls (n = 159) and the largest cross-sectional sample of patients with remitted psychotic depression (n = 86) collected to date. All patients participated in the Study of Pharmacotherapy of Psychotic Depression II randomized controlled trial. We used a novel, whole-brain, data-driven parcellation technique-non-negative matrix factorization-and applied it to cortical thickness data to derive structural covariance networks. We compared patients with remitted psychotic depression to healthy controls and found that patients had significantly thinner cortex in five structural covariance networks (insular-limbic, occipito-temporal, temporal, parahippocampal-limbic, and inferior fronto-temporal), confirming our hypothesis that affected brain networks would incorporate cortico-limbic regions. We also found that cross-sectional depression and severity scores at the time of scanning were associated with the insular-limbic network. Furthermore, the insular-limbic network predicted future severity scores that were collected at the time of recurrence of psychotic depression or sustained remission. Overall, decreased cortical thickness was found in five structural brain networks in patients with remitted psychotic depression and brain-behavior relationships were observed, particularly between the insular-limbic network and illness severity.

Background: Some patients with major depression continue to demonstrate deficits in health-related quality of life (HRQL) following remission. No data exist, however, regarding HRQL in remitted psychotic depression. In this study, we aimed to characterize HRQL in patients with psychotic depression receiving controlled pharmacotherapy., Methods: This is a secondary analysis of a randomized controlled trial studying continuation pharmacotherapy of psychotic depression. We compared participants' HRQL (measured using the SF-36) between baseline and remission and to population norms. We also compared SF-36 scores stratified by age and gender and examined the correlation between SF-36 scores and medical burden, depression score and neuropsychological performance in remission., Results: SF-36 scores were significantly lower than population norms at baseline, but improved following remission to the level of population norms. Neither SF-36 scores nor magnitude of SF-36 improvement differed substantially between genders or between younger and older participants. In remission, depression scores were correlated with most SF-36 scales and medical burden was correlated with SF-36 scales measuring physical symptoms. Neuropsychological measures were generally not correlated with SF-36 scores., Limitations: This study was a secondary analysis not powered specifically to measure HRQL as an outcome variable and the SF-36 was the only HRQL measure used., Conclusions: Participants with remitted psychotic depression demonstrated levels of HRQL comparable to population norms, despite marked impairment in HRQL when acutely ill. This finding suggests that, when treated in a rigorous manner, many patients with this severe illness improve significantly from a clinical and HRQL perspective., (Copyright © 2019.

Importance: Psychotic depression is a severely disabling and potentially lethal disorder. Little is known about the efficacy and tolerability of continuing antipsychotic medication for patients with psychotic depression in remission., Objective: To determine the clinical effects of continuing antipsychotic medication once an episode of psychotic depression has responded to combination treatment with an antidepressant and antipsychotic agent., Design, Setting, and Participants: Thirty-six week randomized clinical trial conducted at 4 academic medical centers. Patients aged 18 years or older had an episode of psychotic depression acutely treated with sertraline plus olanzapine for up to 12 weeks and met criteria for remission of psychosis and remission or near-remission of depressive symptoms for 8 weeks before entering the clinical trial. The study was conducted from November 2011 to June 2017, and the final date of follow-up was June 13, 2017., Interventions: Participants were randomized either to continue olanzapine (n = 64) or switch from olanzapine to placebo (n = 62). All participants continued sertraline., Main Outcomes and Measures: The primary outcome was risk of relapse. Main secondary outcomes were change in weight, waist circumference, lipids, serum glucose, and hemoglobin A1c (HbA1c)., Results: Among 126 participants who were randomized (mean [SD] age, 55.3 years [14.9 years]; 78 women [61.9%]), 114 (90.5%) completed the trial. At the time of randomization, the median dosage of sertraline was 150 mg/d (interquartile range [IQR], 150-200 mg/d) and the median dosage of olanzapine was 15 mg/d (IQR, 10-20 mg/d). Thirteen participants (20.3%) randomized to olanzapine and 34 (54.8%) to placebo experienced a relapse (hazard ratio, 0.25; 95% CI, 0.13 to 0.48; P < .001). The effect of olanzapine on the daily rate of anthropometric and metabolic measures significantly differed from placebo for weight (0.13 lb; 95% CI, 0.11 to 0.15), waist circumference (0.009 inches; 95% CI, 0.004 to 0.014), and total cholesterol (0.29 mg/dL; 95% CI, 0.13 to 0.45) but was not significantly different for low-density lipoprotein cholesterol (0.04 mg/dL; 95% CI, -0.01 to 0.10), high-density lipoprotein cholesterol (-0.01 mg/dL; 95% CI, -0.03 to 0.01), triglyceride (-0.153 mg/dL; 95% CI, -0.306 to 0.004), glucose (-0.02 mg/dL; 95% CI, -0.12 to 0.08), or HbA1c levels (-0.0002 mg/dL; 95% CI, -0.0021 to 0.0016)., Conclusions and Relevance: Among patients with psychotic depression in remission, continuing sertraline plus olanzapine compared with sertraline plus placebo reduced the risk of relapse over 36 weeks. This benefit needs to be balanced against potential adverse effects of olanzapine, including weight gain., Trial Registration: ClinicalTrials.gov Identifier: NCT01427608.

Background: There is paucity of neurobiological knowledge about major depressive disorder with psychotic features ("psychotic depression"). This study addresses this knowledge gap by using resting state functional magnetic resonance imaging (R-fMRI) to compare functional connectivity in patients with psychotic depression and healthy controls., Methods: We scanned patients who participated in a randomized controlled trial as well as healthy controls. All patients achieved remission from depressive and psychotic symptoms with sertraline and olanzapine. We employed Independent Component Analysis in independent samples to isolate the default mode network (DMN) and compared patients and controls., Findings: The Toronto sample included 28 patients (mean [SD], age 56·2 [13·7]) and 39 controls (age 55·1 [13·5]). The Replication sample included 29 patients (age 56·1 [17·7]) and 36 controls (age 48·3 [17·9]). Patients in the Toronto sample demonstrated decreased between-network functional connectivity between the DMN and bilateral insular, somatosensory/motor, and auditory cortices with peak activity in the right planum polare (t = 4·831; p = 0·001, Family Wise Error (FWE) corrected). A similar pattern of between-network functional connectivity was present in our Replication sample with peak activity in the right precentral gyrus (t = 4·144; p = 0·003, FWE corrected)., Interpretation: Remission from psychotic depression is consistently associated with an absence of increased DMN-related functional connectivity and presence of decreased between-network functional connectivity. Future research will evaluate this abnormal DMN-related functional connectivity as a potential biomarker for treatment trajectories., Funding: National Institute of Mental Health., (Copyright © 2018 The Authors.

Objective: We conducted a 12-week double-blind study of stabilization pharmacotherapy in patients with remitted psychotic depression (PD)., Methods: Seventy-one persons aged 18 years or older who had achieved remission of PD when randomized to either olanzapine plus sertraline or olanzapine plus placebo were continued on the double-blind treatment associated with remission. Symptoms of depression and psychosis, and weight, were measured once every 4 weeks. Cholesterol, triglycerides, and glucose were measured at stabilization phase baseline and Week 12/termination., Results: The effect of treatment did not significantly change with time for depression, weight, or metabolic measures in the stabilization phase. Eight of the 71 participants (11.3%; 95% CI: 5.8, 20.7) experienced a relapse of major depression, psychosis, or both. Treatment groups did not differ in the frequency of relapse. In the entire study group, the adjusted estimate for change in weight was an increase of 1.66 kg (95% CI: 0.83, 2.48) and the adjusted estimate for change in total cholesterol was a decrease of 14.8 mg/dL (95% CI: 3.5, 26.1) during the 12-week stabilization phase; the remaining metabolic measures did not significantly change., Conclusion: Continuation of acute treatment was associated with stability of remission., (© 2018 John Wiley & Sons A/S.

Objective: To examine the association between baseline suicidality and outcome of major depression in a randomized controlled trial of the pharmacotherapy of psychotic depression and to explore the interaction of suicidality, randomized treatment assignment, and depression outcome., Methods: This study was a secondary analysis of data from 258 persons aged 18 years or older with DSM-IV-defined major depressive disorder with psychotic features who participated in a 12-week randomized controlled trial (RCT) comparing olanzapine plus sertraline with olanzapine plus placebo (the Study of the Pharmacotherapy of Psychotic Depression [STOP-PD], which ran from 2002 to 2007). The independent variable was baseline suicidality, defined by 4 groups (suicide attempt in the current episode, active suicidal ideation, passive suicidal ideation, and no suicidality). The outcome variables were change in 16-item Hamilton Depression Rating Scale (HDRS₁₆) total score (excluding the suicide item) over time and remission of psychotic depression over time., Results: Suicidality groups did not significantly differ on baseline HDRS₁₆ total score. Baseline suicidality group was significantly associated with change in HDRS₁₆ score over time in the sample as a whole (F₃,₁₃₉₄ = 8.17; P < .0001), but was not significantly associated with probability of remission over time. Among participants assigned to olanzapine and placebo, persons with no suicidality had a significantly greater reduction in HDRS₁₆ total score compared to those with passive suicidal ideation (7.5-point difference in change scores between the 2 groups; 95% CI, 4.3-10.7 t₁₃₉₄ = 4.61, P < .0001), active suicidal ideation (4.4 points; 95% CI, 1.4-7.4; t₁₃₉₄ = 2.85, P = .0176), or suicide attempts (6.1 points; 95% CI, 2.8-9.4; t₁₃₉₄ = 3.66, P = .0015). The 12-week change from baseline in HDRS₁₆ score for patients with no suicidality was not significantly different between the 2 treatment arms. However, the 12-week HDRS₁₆ improvement was significantly greater in the olanzapine plus sertraline arm, compared with the olanzapine plus placebo arm, for patients with suicide attempts (8.7-point difference in change scores between the 2 groups; 95% CI, 5.1-12.4; t₁₃₉₄ = 4.75, P < .0001), active suicidal ideation (8.1 points; 95% CI, 4.5-11.7; t₁₃₉₄ = 4.38, P < .0001), or passive suicidal ideation (5.7 points; 95% CI, 2.2-9.2; t₁₃₉₄ = 3.23, P = .0012), respectively., Conclusions: Baseline suicidality predicted worse acute treatment outcome of psychotic depression. However, participants with suicidality had a better outcome when treated with the combination of olanzapine and sertraline than when treated with olanzapine plus placebo., Trial Registration: ClinicalTrials.gov identifier: NCT00056472​., (© Copyright 2017 Physicians Postgraduate Press, Inc.)

Objective: To characterize cognitive function at baseline and investigate the relationship between change in cognition, depression, and psychosis after treatment among older adults with major depressive disorder with psychotic features., Methods: This was a secondary analysis of a double-blind, randomized, controlled treatment trial at inpatient and outpatient settings at four academic health centers on "Young Old" (aged 60-71 years, N = 71) and "Older" (aged 72-86 years, N = 71) participants diagnosed with psychotic depression. Olanzapine plus sertraline or olanzapine plus placebo were given until week 12 or termination., Results: At baseline, Young Old and Older participants did not differ on measures of depression severity or global cognition, information processing speed, and executive function. Improvement in depressive and psychotic symptoms from baseline to treatment end was similar in both the Young Old and Older groups. However, improvement in depressive symptoms was significantly associated with improvement in global cognitive function in Young Old participants but not in Older participants., Conclusion: Cognitive dysfunction was not a detriment to improvement in symptoms of psychotic major depression in our geriatric patients. Young Old and Older patients improved to a similar degree on measures of depression and delusions from baseline to treatment end. However, improvement in cognition over the course of treatment was more prominent in the Young Old group than in the Older group., (Copyright © 2017 American Association for Geriatric Psychiatry.

Objective: We recently reported an unexpected interaction between olanzapine and sertraline in a population being treated for psychotic depression. Contrary to knowledge of cytochrome p450 interactions sertraline increased apparent clearance of olanzapine by 30%. Here we examined the pharmacokinetics of sertraline in the same population. Existing studies suggest that sertraline apparent clearance is significantly increased in male subjects and suggested an age/sex interaction., Methods: We studied subjects undergoing combination of sertraline/olanzapine treatment for psychotic depression in the Study of the Pharmacotherapy of Psychotic Depression. Nonlinear mixed effect modelling software was used to examine the sertraline pharmacokinetics, evaluating age, sex, race, and olanzapine exposure as covariates., Results: Eighty-seven subjects (median age 62 years, 28 male subjects, 11 African-Americans) provided 138 samples for sertraline concentration. Olanzapine exposure had a 14.8-fold range. A one compartment model with combined residual error described the sertraline concentration data adequately. Half-life and sex effect on sertraline apparent clearance (males averaging 50% higher (p < 0.005); 96.6 l/h vs 64.8 in female subjects) were similar to previous reports. No other covariate (age, race or olanzapine exposure) had a significant impact on apparent clearance, and no age/sex interaction emerged., Conclusion: Sertraline pharmacokinetics were similar to historical descriptions in populations not taking antipsychotics. Unlike our unexpected finding that sertraline increases olanzapine apparent clearance, olanzapine exposure had no impact on sertraline pharmacokinetics.

Background: The Psychotic Depression Assessment Scale (PDAS) is a rating scale dedicated to the measurement of severity in psychotic depression (PD). The aim of this study was to establish the PDAS cut-off for remission of PD as well as PDAS score-ranges for mild, moderate, and severe PD. The secondary aim was to test how remission, as defined by the PDAS, would perform as outcome measure when applied to the data from a large randomized controlled trial (RCT) in PD., Methods: The study was based on data from the Study of Pharmacotherapy in Psychotic Depression (STOP-PD). The cut-off for remission on the PDAS and the severity-ranges for mild, moderate, and severe PD were defined using the Clinical Global Impression - Severity scale (CGI-S) as reference by means of pair-wise receiver operating characteristic (ROC) analyses. Subsequently, it was tested whether remission on the PDAS could separate the effects of Olanzapine+Sertraline vs. Olanzapine+Placebo through an intention-to-treat, mixed-effects logistic regression of the data from STOP-PD., Results: According to the ROC analyses, the ideal cut-off for remission of PD was a PDAS total score <8, while the severity-ranges for mild, moderate and severe PD were 8-15, 16-23, and >23 respectively. When applying the PDAS total score <8 (remission) as outcome on the STOP-PD data, treatment with Olanzapine+Sertraline performed significantly better than Olanzapine+Placebo (p<0.001)., Limitations: The STOP-PD was not designed specifically to answer the research questions of the present study., Conclusions: According to this study, a total score <8 on the PDAS corresponds to remission of PD., (Copyright © 2015 Elsevier B.V.

Objective: To examine whether cerebrovascular risk, executive function, and processing speed are associated with acute treatment outcome of psychotic depression in older adults., Methods: The authors analyzed data from 142 persons aged 60 years or older with major depression with psychotic features who participated in a 12-week randomized controlled trial (RCT) comparing olanzapine plus sertraline with olanzapine plus placebo. The independent variables were baseline cerebrovascular risk (Framingham Stroke Risk Score), baseline executive function (Stroop interference score and the initiation/perseveration subscale of the Mattis Dementia Rating Scale), and baseline processing speed (color and word reading components of the Stroop). The outcome variable was change in severity of depression, measured by the 17-item Hamilton Depression Rating Scale total score, during the course of the RCT., Results: Greater baseline cerebrovascular risk was significantly associated with less improvement in depression severity over time, after controlling for pertinent covariates. Neither executive function nor processing speed predicted outcome., Conclusion: This study suggests an association of cerebrovascular risk, but not executive function or processing speed, with treatment outcome of major depression with psychotic features in older adults., (Copyright © 2015 American Association for Geriatric Psychiatry.
