The impact of pharmacological and non-pharmacological interventions on physical health outcomes in people with mood disorders across the lifespan: An umbrella review of the evidence from randomised controlled trials.

OBJECTIVE: People with mood disorders have increased risk of comorbid medical diseases versus the general population. It is paramount to identify interventions to improve physical health in this population. METHODS: Umbrella review of meta-analyses of randomised controlled trials (RCTs) on pharmacological/non-pharmacological interventions for physical health outcomes/intolerability-related discontinuation in mood disorders (any age). RESULTS: Ninety-seven meta-analyses were included. Among youths, against placebo, in depression, antidepressants/antipsychotics had higher discontinuation rates; in bipolar depression, olanzapine+fluoxetine worsened total cholesterol (TC)/triglycerides/weight gain (WG) (large ES). In adults with bipolar disorder, olanzapine worsened HbA1c/TC/WG (moderate/large ES); asenapine increased fasting glucose (small ES); quetiapine/cariprazine/risperidone induced WG (small/moderate ES). In bipolar depression, lurasidone was metabolically neutral. In depression, psychological interventions improved physical health-related quality of life (PHQoL) (small ES), fasting glucose/HbA1c (medium/large ES); SSRIs improved fasting glucose/HbA1c, readmission for coronary disease, pain (small ES); quetiapine/aripiprazole/olanzapine induced WG (small to large ES). Exercise improved cardiorespiratory fitness (moderate ES). In the elderly, fluoxetine yielded more detrimental cardiovascular effects than sertraline/escitalopram (large ES); antidepressants were neutral on exercise tolerance and PHQoL. In mixed age groups, in bipolar disorder aripiprazole was metabolically neutral; in depression, SSRIs lowered blood pressure versus placebo and serotonin-noradrenaline reuptake inhibitors (small ES); brexpiprazole augmentation caused WG and was less tolerated (small ES); exercise improved PHQoL (moderate ES). CONCLUSIONS: Some interventions (psychological therapies, exercise and SSRIs) improve certain physical health outcomes in mood disorders, few are neutral, but various pharmacological interventions are associated with negative effects. Evidence from this umbrella review has limitations, should consider evidence from other disorders and should be integrated with recent evidence from individual RCTs, and observational evidence. Effective treatments with either beneficial or physically neutral profiles should be prioritized.

Changes associated with the COVID-19 pandemic on postpartum screening results in Ontario, Canada: The healthy babies healthy children screening tool.

BACKGROUND: Research on the impact of the COVID-19 pandemic on mothers/childbearing parents has mainly been cross-sectional and focused on psychological symptoms. This study examined the impact on function using ongoing, systematic screening of a representative Ontario sample. METHODS: An interrupted time series analysis of repeated cross-sectional data from a province-wide screening program using the Healthy Babies Healthy Children (HBHC) tool assessed changes associated with the pandemic at the time of postpartum discharge from hospital. Postal codes were used to link to neighborhood-level data. The ability to parent or care for the baby/child and other psychosocial and behavioral outcomes were assessed. RESULTS: The co-primary outcomes of inability to parent or care for the baby/child were infrequently observed in the pre-pandemic (March 9, 2019-March 15, 2020) and initial pandemic periods (March 16, 2020-March 23, 2021) (parent 209/63,006 (0.33%)-177/56,117 (0.32%), care 537/62,955 (0.85%)-324/56,086 (0.58%)). Changes after pandemic onset were not observed for either outcome although a significant (p = 0.02) increase in slope was observed for inability to parent (with questionable clinical significance). For secondary outcomes, worsening was only seen for reported complications during labor/delivery. Significant improvements were observed in the likelihood of being unable to identify a support person to assist with care, need of newcomer support, and concerns about money over time. CONCLUSIONS: There were no substantive changes in concerns about ability to parent or care for children. Adverse impacts of the pandemic may have been mitigated by accommodations for remote work and social safety net policies.

Posterior Fossa Sub-Arachnoid Cysts Observed in Patients with Bipolar Disorder: a Retrospective Cohort Study.

Posterior fossa arachnoid cysts (PFACs) are rare congenital abnormalities observed in 0.3 to 1.7% of the population and are traditionally thought to be benign. While conducting a neuroimaging study investigating cerebellar structure in bipolar disorder, we observed a higher incidence of PFACs in bipolar patients (5 of 75; 6.6%) compared to the neuronormative control group (1 of 54; 1.8%). In this report, we detail the cases of the five patients with bipolar disorder who presented with PFACs. Additionally, we compare neuropsychiatric measures and cerebellar volumes of these patients to neuronormative controls and bipolar controls (those with bipolar disorder without neuroanatomical abnormalities). Our findings suggest that patients with bipolar disorder who also present with PFACs may have a milder symptom constellation relative to patients with bipolar disorder and no neuroanatomical abnormalities. Furthermore, our observations align with prior literature suggesting an association between PFACs and psychiatric symptoms that warrants further study. While acknowledging sample size limitations, our primary aim in the present work is to highlight a connection between PFACs and BD-associated symptoms and encourage further study of cerebellar abnormalities in psychiatry.

Homelessness and health-related outcomes: an umbrella review of observational studies and randomized controlled trials.

BACKGROUND: Homelessness has been associated with multiple detrimental health outcomes across observational studies. However, relatively few randomized controlled trials (RCTs) have been conducted on people who experience homelessness (PEH). Thus, this umbrella review ranked the credibility of evidence derived from systematic reviews (SRs) and meta-analyses (MAs) of observational studies investigating the associations between homelessness and any health outcome as well as RCTs targeting health needs in this population. METHODS: Several databases were systematically searched from inception through April 28, 2021. Any SR and/or MA reporting quantitative data and providing a control group were eligible for inclusion. The credibility of the evidence derived from observational studies was appraised by considering the significance level of the association and the largest study, the degree of heterogeneity, the presence of small-study effects as well as excess significance bias. The credibility of evidence was then ranked in five classes. For SRs and/or MAs of RCTs, we considered the level of significance and whether the prediction interval crossed the null. The AMSTAR-2 and AMSTAR-plus instruments were adopted to further assess the methodological quality of SRs and/or MAs. The Newcastle-Ottawa Scale (NOS) was employed to further appraise the methodological quality of prospective cohort studies only; a sensitivity analysis limited to higher quality studies was conducted. RESULTS: Out of 1549 references, 8 MAs and 2 SRs were included. Among those considering observational studies, 23 unique associations were appraised. Twelve of them were statistically significant at the p≤0.005 level. Included cases had worst health-related outcomes than controls, but only two associations reached a priori-defined criteria for convincing (class I) evidence namely hospitalization due to any cause among PEH diagnosed with HIV infection, and the occurrence of falls within the past year among PEH. According to the AMSTAR-2 instrument, the methodological quality of all included SRs and/or MAs was "critically low." Interventional studies were scant. CONCLUSION: While homelessness has been repeatedly associated with detrimental health outcomes, only two associations met the criteria for convincing evidence. Furthermore, few RCTs were appraised by SRs and/or MAs. Our umbrella review also highlights the need to standardize definitions of homelessness to be incorporated by forthcoming studies to improve the external validity of the findings in this vulnerable population.

A week long "pep" talk - initial and 2-3-year longitudinal data on the Ottawa Psychiatry Enrichment Program (OPEP).

BACKGROUND: Recruitment to psychiatry as a career has been challenging in Canada and abroad despite the known shortage and increasing burden of psychiatric issues globally. Deterrents to choosing psychiatry as a career include its negative stigma and paucity of knowledge about the field. The study goal was to evaluate the Ottawa Psychiatry Enrichment Program (OPEP), a one-week extracurricular program about psychiatry as a career for 1st and 2nd year medical students. We hypothesized OPEP would improve students' attitudes towards psychiatry, and positive changes would be sustained 2-3 years later following their residency match. We hypothesized there would be a high recruitment of OPEP attendees to psychiatry programs. METHODS: 1st and 2nd year medical students from Canada applied to OPEP. Attendees completed the Attitudes Towards Psychiatry Questionnaire (ATP-30) at three times: before OPEP (PreOPEP), after OPEP (PostOPEP) and after their Canadian Residency Matching Service (CaRMs) match 2-3 years later. OPEP ATP-30 scores were compared to third-year student ATP-30 scores before and after their psychiatry rotation. Data were analysed using Friedman non-parametric ANOVA and post hoc testing by either Wilcoxon rank sum test, Wilcoxon matched pairs signed rank test, or parametric Welch independent t-test as appropriate. Effect sizes of group mean differences were calculated using Cohen's "d". RESULTS: Between 2017-2018, 29/53 Canadian applicants were selected for OPEP. 100%, 93.1% and 75.8% of OPEP students completed the PreOPEP, PostOPEP, and CaRMs ATP-30 surveys respectively. 43% of OPEP attendees matched to psychiatry. PostOPEP ATP-30 scores (mean = 133, median = 137, SD = 10.6) were significantly higher than PreOPEP ATP-30 (mean score = 121, median = 122, SD = 9.3, p < 0.001) and CaRMS ATP-30 (mean = 126, median = 127, SD = 12.3, p < 0.02) scores. OPEP effect size on ATP-30 scores was large (d = 1.2) but decreased 2-3 years later (p = 0.078, d = 0.44). 97/202 students completed the ATP-30 before and after their psychiatry rotation (clerkship). Clerkship effect size on improvement in ATP-30 was moderate (d = 0.39). There was a non-significant difference between OPEP CaRMS ATP-30 and post clerkship ATP-30 scores (median 127 vs 121, p = 0.056). CONCLUSIONS: OPEP ameliorated attitudes toward Psychiatry, but improvement deteriorated longitudinally. Strategies for program design, and innovations to boost/retain improvements during clerkship years are discussed.

Changes in Attitudes and Confidence in the Integration of Psychiatry in Other Areas of Medicine.

OBJECTIVE: The authors describe how attitudes and confidence in the integration of psychiatry into other areas of medicine change over time during clinical clerkship in medical school. METHODS: From January 2015 to December 2016, medical students from the University of Iowa were recruited for a prospective study of changes in the Attitudes and Confidence in the Integration of Psychiatry Scale (ACIP) scale. The survey instrument was completed before their psychiatry clerkship, after the clerkship, and at the end of the year following that and other clinical clerkships. Other information such as gender, time spent in clerkship, USMLE Step 1 score, and clerkship grades was also collected. RESULTS: A total of 172 surveys were completed by 138 students. The ACIP score was significantly higher at the end of the participants' clinical clerkship (67.2 to 76.6; t=-7.72, p<0.0001). Of the two ACIP subscales, confidence increased significantly (25.6 to 33.3; t=-9.82, p<0.0001), but attitudes toward integration of psychiatry did not (41.7 to 43.4; t=-1.96, p=0.059). Similar findings were seen in the subset of 34 students for whom pre- and post-clerkship data could be matched. CONCLUSIONS: At the end of their clinical clerkship, medical students feel more confident providing psychiatric care. The lack of significant increase in the ACIP scale's attitude subscale either demonstrates that attitude scores going into clerkship were already high and did not deteriorate, or highlights an area for clerkship curriculum development.

A randomized controlled trial for symptoms of anxiety and depression: Effects of a 1-day acceptance and commitment training workshop.

BACKGROUND: Cognitive-behavioral therapies often are recommended for anxiety disorders. However, treatment adherence and compliance are major barriers for these treatments, which are often delivered in 10 to 12 sessions over several months. This randomized controlled trial (trial registration NCT02915874 at www.clinicaltrials.gov) examined the effectiveness and feasibility of a 1-day cognitive-behavioral intervention for mixed anxiety. METHODS: A total of 72 adults with moderate-to-high anxiety were randomized into a 1-day acceptance and commitment therapy (ACT) work-shop (n = 44) or treatment as usual (n = 28). Follow-up assessments were conducted 6 and 12 weeks after the workshop. Clinical outcomes were anxiety (primary) and depressive (secondary) symptoms, as measured by the Beck Anxiety Inventory and Beck Depression Inventory-II, respectively. Proposed mediators of ACT-psychological flexibility and commit-ted action-also were examined. RESULTS: Participants assigned to the ACT workshop showed significant improvements in anxiety (beta = -1.13; P = .02) and depression (beta = -1.09; P = .02) after 12 weeks. Consistent with the theoretical model, these clinical improvements were mediated by psychological flexibility and committed action. Notable limitations included the sample size, inability to blind to treatment condition, and a racially and ethnically homogeneous sample. CONCLUSIONS: Our 1-day ACT workshop was effective for anxiety with co-occurring depressive symptoms. One-day interventions are a promising alternative to weekly treatments.

Management of Cardiovascular Health in People with Severe Mental Disorders.

PURPOSE OF REVIEW: To review evidence regarding the association between bipolar disorder and schizophrenia, henceforth referred to as severe mental disorders (SMD), and cardiovascular morbidity and mortality, its mechanisms, and the interventions to reduce this burden. RECENT FINDINGS: Much of the loss in life expectancy in people with SMD remains driven by cardiovascular mortality. Antipsychotics and mood stabilizers are associated with negative cardio-metabolic outcomes, but large inter-individual differences are observed, and not treating SMD might be associated with even greater cardiovascular mortality. Classical modifiable cardiovascular risk factors remained inadequately screened and, once identified, too seldom treated in people with SMD. After a myocardial infarction, aggressive tertiary prevention may be as effective in people with SMD as in the general population but is less prescribed. Reduced healthcare quality and increased prevalence of cardiovascular risk factors may not fully explain the excess cardiovascular mortality associated with SMDs, which themselves should be considered risk factors in risk calculators. Hazardous health behaviors, the cardio-metabolic adverse effects of medications, and a reduced access to quality healthcare remain priority targets for intervention.

Call to action regarding the vascular-bipolar link: A report from the Vascular Task Force of the International Society for Bipolar Disorders.

OBJECTIVES: The association of bipolar disorder with early and excessive cardiovascular disease was identified over a century ago. Nonetheless, the vascular-bipolar link remains underrecognized, particularly with regard to how this link can contribute to our understanding of pathogenesis and treatment. METHODS: An international group of experts completed a selective review of the literature, distilling core themes, identifying limitations and gaps in the literature, and highlighting future directions to bridge these gaps. RESULTS: The association between bipolar disorder and vascular disease is large in magnitude, consistent across studies, and independent of confounding variables where assessed. The vascular-bipolar link is multifactorial and is difficult to study given the latency between the onset of bipolar disorder, often in adolescence or early adulthood, and subsequent vascular disease, which usually occurs decades later. As a result, studies have often focused on risk factors for vascular disease or intermediate phenotypes, such as structural and functional vascular imaging measures. There is interest in identifying the most relevant mediators of this relationship, including lifestyle (eg, smoking, diet, exercise), medications, and systemic biological mediators (eg, inflammation). Nonetheless, there is a paucity of treatment studies that deliberately engage these mediators, and thus far no treatment studies have focused on engaging vascular imaging targets. CONCLUSIONS: Further research focused on the vascular-bipolar link holds promise for gleaning insights regarding the underlying causes of bipolar disorder, identifying novel treatment approaches, and mitigating disparities in cardiovascular outcomes for people with bipolar disorder.

Impact of preexisting mental illness on breast cancer endocrine therapy adherence.

PURPOSE: Patients with estrogen receptor positive (ER+) breast cancer are often non-adherent to endocrine therapies, despite clear survival benefits. We utilized a nationally representative cancer cohort to examine the role of specific mental illnesses on endocrine therapy adherence. METHODS: Using the SEER-Medicare database, we included 21,894 women aged 68+ at their first surgically treated stage I-IV ER+ breast cancer during 2007-2013. All had continuous fee-for-service Medicare Parts A and B for 36+ months before, 18+ months after diagnosis, and continuous Part D for 4+ months before, 18+ after diagnosis. Mental illness was defined as occurring in the 36 months prior to cancer onset. We analyzed endocrine therapy adherence, initiation, and discontinuation using longitudinal linear and Cox regression models. RESULTS: Unipolar depression (11.0%), anxiety (9.5%), non-schizophrenia psychosis (4.6%), and dementias (4.6%) were the most prevalent diagnoses. Endocrine therapies were initiated by 80.0% of women. Among those with at least one year of use, 28.0% were non-adherent (< 0.80 adherence, mean = 0.84) and 25.7% discontinued. Patients with dementia or bipolar depression/psychotic/schizophrenia disorders had lower adjusted initiation probabilities by year one of follow-up, versus those without these diagnoses [0.74 95% CI (0.73-0.74) and 0.73 (0.72-0.73), respectively, reference 0.76 (0.76-0.77)]. Patients with substance use or anxiety disorders less frequently continued endocrine therapy for at least one year, after adjustment, [0.85 95% CI (0.85-0.86) and 0.88 (0.87-0.88), respectively, reference 0.90 (0.89-0.90)]. Patients with substance use disorders had 2.3% lower adherence rates (p < 0.001). CONCLUSIONS: Nearly one-quarter of female Medicare beneficiaries have diagnosed mental illness preceding invasive breast cancer. Those with certain mental illnesses have modestly reduced rates of initiation, adherence, and discontinuation and this may help define patients at higher risk of treatment abandonment. Overall, endocrine therapy adherence remains suboptimal, unnecessarily worsening recurrence and mortality risk.

Changes in inflammation with treatment for bipolar II depression: Pilot trial data on differential effects of psychotherapy and medication.

OBJECTIVES: Limited prospective data, mostly focused on bipolar I disorder, suggests that pro-inflammatory cytokines are elevated in abnormal mood states. We evaluated whether treatment normalizes peripheral markers of inflammation in bipolar II disorder. METHODS: Using data from a randomized clinical trial of Interpersonal and Social Rhythm Therapy (IPSRT) + quetiapine vs. IPSRT + placebo for bipolar II depression, we examined whether these treatments for bipolar II depression impact inflammatory cytokines and whether observed changes in cytokines are associated with changes in depressive symptomatology as measured by the Hamilton Rating Scale for Depression (HRSD-17). RESULTS: Cytokine values were available for 33 participants who completed baseline and 20-week followup visits. After excluding those with CRP values >=10 mg/L, there were 27 patients available for analysis (IPSRT+quetiapine N=10, IPSRT+placebo N=17). Baseline measure of inflammation did not appear to moderate treatment response, nor was change in HRSD-17 score correlated with changes in cytokines. Those who received IPSRT+quetiapine had significantly greater increases in IL-6 (p=0.02) and TNF-α (p=0.04), even after adjusting for changes in body mass index, than the IPSRT alone group. Descriptively, the quetiapine group showed increases in pro-inflammatory and decreases in anti-inflammatory cytokines and the psychotherapy group showed reduced pro-inflammatory cytokines. CONCLUSIONS: Despite both groups showing depression improvement, this small study suggests a more pro-inflammatory cytokine profile over time with quetiapine plus psychotherapy compared to psychotherapy alone. Elevated risk of cardiovascular morbidity and mortality among those with bipolar II disorder underscores the importance of delivering treatments that do not exacerbate these risk factors.

Relative burst amplitude of muscle sympathetic nerve activity is an indicator of altered sympathetic outflow in chronic anxiety.

Relative burst amplitude of muscle sympathetic nerve activity (MSNA) is an indicator of augmented sympathetic outflow and contributes to greater vasoconstrictor responses. Evidence suggests anxiety-induced augmentation of relative MSNA burst amplitude in patients with panic disorder; thus we hypothesized that acute stress would result in augmented relative MSNA burst amplitude and vasoconstriction in individuals with chronic anxiety. Eighteen participants with chronic anxiety (ANX; 8 men, 10 women, 32 ± 2 yr) and 18 healthy control subjects with low or no anxiety (CON; 8 men, 10 women, 39 ± 3 yr) were studied. Baseline MSNA and 24-h blood pressure were similar between ANX and CON ( P > 0.05); however, nocturnal systolic blood pressure % dipping was blunted among ANX ( P = 0.02). Relative MSNA burst amplitude was significantly greater among ANX compared with CON immediately preceding (anticipation) and during physiological stress [2-min cold pressor test; ANX: 73 ± 5 vs. CON: 59 ± 3% arbitrary units (AU), P = 0.03] and mental stress (4-min mental arithmetic; ANX: 65 ± 3 vs. CON: 54 ± 3% AU, P = 0.02). Increases in MSNA burst frequency, incidence, and total activity in response to stress were not augmented among ANX compared with CON ( P > 0.05), and reduction in brachial artery conductance during cold stress was similar between ANX and CON ( P = 0.92). Relative MSNA burst amplitude during mental stress was strongly correlated with state ( P < 0.01) and trait ( P = 0.01) anxiety (State-Trait Anxiety Inventory), independent of age, sex, and body mass index. Thus in response to acute stress, both mental and physiological, individuals with chronic anxiety demonstrate selective augmentation in relative MSNA burst amplitude, indicating enhanced sympathetic drive in a population with higher risk for cardiovascular disease. NEW & NOTEWORTHY Relative burst amplitude of muscle sympathetic nerve activity in response to acute mental and physiological stress is selectively augmented in individuals with chronic anxiety, which is a prevalent condition that is associated with the development of cardiovascular disease. Augmented sympathetic burst amplitude occurs with chronic anxiety in the absence of common comorbidities. These findings provide important insight into the relation between anxiety, acute stress and sympathetic activation.

Mixed state and suicide: Is the effect of mixed state on suicidal behavior more than the sum of its parts?

OBJECTIVE: To assess whether suicidal behavior during mixed states exceeds that expected from the manic or depressive components alone. METHODS: This study included 429 participants with bipolar disorder from the National Institute of Mental Health Collaborative Depression Study (CDS). Mood and suicidal behavior were captured using the Longitudinal Interval Follow-up Evaluation and the Schedule of Affective Disorders and Schizophrenia. Suicidal behavior during each mood state, relative to euthymia, was analyzed using Cox regression to allow for repeated events, with a frailty term to account for intra-participant correlation. Mixed states were modeled as a depression-by-mania interaction. RESULTS: Individuals with a history of mixed states were at higher risk of suicidal behavior and spent more time depressed, compared to subjects with no such history. In bipolar I disorder, risk increased during episodes of mania (hazard ratio [HR]: 1.96, 95% confidence interval [CI]: 1.28-2.99, P = .0019) and depression (HR: 5.49, 95% CI: 4.01-7.51, P < .0001) and there was a less than additive effect of mixed states. In bipolar II disorder, risk was increased during episodes of depression (HR: 3.66, 95% CI: 2.51-5.35, P < .0001) and there was no excess risk during mixed states beyond that attributable to the depressed component. Most of the excess risk (71%) among those with a history of mixed states was attributable to a depression predominant course of illness. CONCLUSIONS: Individuals with mixed states are at high risk of suicidal behavior, largely due to more time spent depressed. Clinicians should aggressively treat depression to mitigate suicide risk for patients with or without mixed states.

Alterations of the cerebellum and basal ganglia in bipolar disorder mood states detected by quantitative T1ρ mapping.

OBJECTIVES: Quantitative mapping of T1 relaxation in the rotating frame (T1ρ) is a magnetic resonance imaging technique sensitive to pH and other cellular and microstructural factors, and is a potentially valuable tool for identifying brain alterations in bipolar disorder. Recently, this technique identified differences in the cerebellum and cerebral white matter of euthymic patients vs healthy controls that were consistent with reduced pH in these regions, suggesting an underlying metabolic abnormality. The current study built upon this prior work to investigate brain T1ρ differences across euthymic, depressed, and manic mood states of bipolar disorder. METHODS: Forty participants with bipolar I disorder and 29 healthy control participants matched for age and gender were enrolled. Participants with bipolar disorder were imaged in one or more mood states, yielding 27, 12, and 13 imaging sessions in euthymic, depressed, and manic mood states, respectively. Three-dimensional, whole-brain anatomical images and T1ρ maps were acquired for all participants, enabling voxel-wise evaluation of T1ρ differences between bipolar mood state and healthy control groups. RESULTS: All three mood state groups had increased T1ρ relaxation times in the cerebellum compared to the healthy control group. Additionally, the depressed and manic groups had reduced T1ρ relaxation times in and around the basal ganglia compared to the control and euthymic groups. CONCLUSIONS: The study implicated the cerebellum and basal ganglia in the pathophysiology of bipolar disorder and its mood states, the roles of which are relatively unexplored. These findings motivate further investigation of the underlying cause of the abnormalities, and the potential role of altered metabolic activity in these regions.

Spaced learning using emails to integrate psychiatry into general medical curriculum: Keep psychiatry in mind.

OBJECTIVES: Traditionally, medical students on clinical rotations receive instruction on principles of mental health only during the psychiatry clerkship. We used emails to insert teaching of psychiatric concepts beyond the psychiatry clerkship into other rotations using the method of spaced learning, the delivery of brief morsels of information repeated over time intervals. We predicted that the intervention would improve attitudes and confidence towards the integration of psychiatry and knowledge retention. METHODS: We developed and distributed a series of emails relating key psychiatric concepts targeted to the other core clerkships. RESULTS: In a cluster-randomized trial over one academic year (intervention group n = 71, control group n = 61), scores on the Attitudes and Confidence in the Integration of Psychiatry scale and on the knowledge quiz did not differ significantly. Students who actively engaged with the emails demonstrated significantly higher scores on the knowledge test. Email users valued the timing, format of delivery and application of psychiatric principles outside the psychiatric setting. Participants recommended simplifying the format and previewing the benefits of spaced learning to increase utilization. CONCLUSION: Delivering spaced learning through emails, within a curriculum designed to foster engagement, may provide an efficient means of addressing the widely-recognized but elusive goal of integrating teaching across medical disciplines.

Attitudes and Confidence in the Integration of Psychiatry Scale.

OBJECTIVE: The authors sought to measure attitudes and confidence in the integration of psychiatry into other fields of medicine. METHODS: The Attitudes and Confidence in Integration of Psychiatry in Medicine (ACIP) scale was developed through discussion with content experts across disciplines and pilot testing of items and administered to third- and fourth-year medical students at University of Iowa, University of Michigan, Rush University for validation, focused on assessment of variability, internal consistency, factor structure, and test-retest reliability. RESULTS: A total of 310 medical students completed the survey (35% participation rate). The scale had a high internal consistency (Cronbach's alpha = 0.88) and was without ceiling or floor effects. Students rated the integration of psychiatry into the practice of surgery and its subspecialties as less relevant than its integration into other specialties; however, scores were not biased by students' interest in procedural vs. non-procedural specialties. Test-retest reliability was high (Cronbach's alpha = 0.90). CONCLUSIONS: The ACIP may serve a useful role in determining the outcome of educational efforts toward integrated care.

Rapid adipose deposition with mood disorders.

BACKGROUND: Persons with bipolar disorder represent a high-risk group for obesity, but little is known about the time course by which weight gain occurs in bipolar disorder. METHODS: We prospectively studied changes in fat distribution using dual-energy x-ray absorptiometry in relationship to medication exposure and mood symptom burden in 36 participants with bipolar disorder. We assessed the relationship between prior medication exposure and course of illness with adiposity measures at baseline (N = 36) and at 6-month follow-up (N = 22). RESULTS: At baseline, greater adiposity was associated with advanced age and female sex, not retrospectively assessed symptom course or medication exposure (past 2 years). Over 6 months of prospective follow-up, participants developed greater adiposity (fat mass index +0.82 kg/m(²), P = .007; visceral fat area +8.6 cm(²), P = .02; total percent fat +1.6%, P = .02). Manic symptomatology, not antipsychotic exposure, was related to the increased adiposity. CONCLUSIONS: Acute exacerbations of mood disorders appear to represent high-risk periods for adipose deposition. Obesity prevention efforts may be necessary during acute exacerbations.

Results of the citalopram to enhance cognition in Huntington disease trial.

BACKGROUND: The objective of this study was to evaluate citalopram for executive functioning in Huntington's disease (HD). METHODS: The study was randomized, double-blind, and placebo-controlled. Thirty-three adults with HD, cognitive complaints, and no depression (Hamilton Depression [HAM-D] rating scale ≤ 12) were administered citalopram 20 mg or placebo (7 visits, 20 weeks), with practice and placebo run-ins. The primary outcome was change in executive functioning. RESULTS: The intent to treat analysis was controlled for practice effects, comparing visits 1 and 2 to visits 5 and 6 for citalopram versus placebo. There were no significant benefits on the executive function composite (treatment-placebo mean difference -0.167; 95% confidence interval [CI], -0.361 to 0.028; P = .092). Citalopram participants showed improved clinician-rated depression symptoms on the HAM-D (t = -2.02; P = 0.05). There were no group differences on motor ratings, self-reported executive functions, psychiatric symptoms, or functional status. CONCLUSIONS: There was no evidence that short-term treatment with citalopram improved executive functions in HD. Despite excluding patients with active depression, participants on citalopram showed improved mood, raising the possibility of efficacy for subsyndromal depression in HD.

Depression and cardiovascular disease: an update on how course of illness may influence risk.

Depression constitutes a novel and independent risk factor for cardiovascular disease, which despite extensive support in the literature has been underappreciated. While much of the evidence for depression as a risk factor for cardiovascular disease is based on studies following myocardial infarction, the elevated vascular risk conveyed by depression is not confined to periods following acute coronary syndromes. For that matter, the risk appears across mood disorders with evidence for even greater risk in bipolar disorder. This review summarizes the literature linking depressive disorders to cardiovascular mortality with a focus on how the course of illness of mood disorders may influence this risk. Mood disorders may influence risk over decades of illness in a dose-response to symptom burden, or the persistence of affective symptomatology. This may be mediated through changes in the activity of the autonomic nervous system, the hypothalamic-pituitary-adrenal axis, and inflammatory cytokines. Whether treatment of depression can mitigate this risk is not established although there are suggestions to support this contention, which could be better studied with more effective treatments of depression and larger standardized samples. Directions for future study of mechanisms and treatment are discussed. Regardless of causal mechanisms, persons with depressive disorders and other risk factors for vascular disease represent a neglected, high-risk group for cardiovascular events. In addition to the appropriate treatment for depression, screening and optimized management of traditional risk factors for cardiovascular diseases is necessary.

Obstructive sleep apnea and risk for late-life depression.

BACKGROUND: Obstructive sleep apnea (OSA) is a sleep-related breathing disorder characterized by repetitive pharyngeal collapse. Because of the association between OSA, ischemia, and late-life depression, we hypothesized that older patients with OSA would have a higher prevalence of depression relative to their younger counterparts. METHODS: We retrospectively reviewed charts of patients evaluated at the Sleep Disorders Center (SDC) at University of Iowa Hospitals and Clinics. A total of 617 patients age≥18 seen at SDC for diagnostic and therapeutic sleep studies were identified. Patients with a chart diagnosis of depressive disorder or treatment with antidepressants were identified as having a depressive disorder. Patients with an Apnea/Hypopnea Index≥5 were identified as having OSA. RESULTS: No evidence of an escalating prevalence of depression with age was found in patients with OSA relative to those without the disorder. Prevalence of depression was similar in the OSA and the nonapnea groups (40.9% vs 40.3%, respectively; χ2=0.02; df=1; P=.89). Individuals with OSA had a significantly higher body mass index and greater number of chart diagnoses of hypertension, diabetes mellitus, and coronary artery disease compared with the nonapnea group. CONCLUSIONS: The prevalence of depression among individuals with OSA does not appear to be moderated by age. Similarly high rates of depression were observed across the population of individuals referred for sleep studies, whether or not they were diagnosed with OSA.
