My long day’s journey into sleep began as an adolescent trying to manage my evening chronotype. The relief I felt when my undergraduate finals were scheduled at night and as a medical student being able to select psychiatry over surgery deepened my interest in sleep and chronobiology. That interest was allowed to flourish at the National Institute...
We conducted a 16-week randomized controlled trial in psychiatric outpatients with a lifetime diagnosis of a mood and/or anxiety disorder to measure the impact of a first-of-its-kind precision digital intervention software solution based on social rhythm regulation principles. The full intent-to-treat (ITT) sample consisted of 133 individuals, aged...

Exercise is presumed to be a potentially helpful smoking cessation adjunct reputed to attenuate the negative effects of deprivation. The present study examined the effectiveness of moderate within-session exercise to reduce 4 key symptoms of smoking deprivation during 3 72-hr nicotine abstinence blocks in both male and female smokers. Forty-nine (2...
Importance
Early identification of individuals at high risk for the onset of bipolar spectrum disorder (BPSD) is key from both a clinical and research perspective. While previous work has identified the presence of a bipolar prodrome, the predictive implications for the individual have not been assessed, to date.
Objective
To build a risk calculat...
Objective:
Current suicide risk screening and measurement are inefficient, have limited measurement precision, and focus entirely on suicide-related items. For this study, a psychometric harmonization between related suicide, depression, and anxiety symptom domains that provides a more balanced and complete spectrum of suicidal symptomatology was...
Background:
Sleep disturbances are a prominent feature of bipolar disorder (BP). However, it remains unclear how sleep phenotypes may evolve among at-risk youth, and their relevance to BP onset.
Methods:
Pittsburgh Bipolar Offspring Study (BIOS) offspring (ages 10-18) and their parents completed assessments approximately every two years pertaini...
Background:
Previous studies have explored the role of stressful life events in the development of mood disorders. We examined the frequency and nature of stressful life events as measured by the Stressful Life Events Schedule (SLES) among 3 groups of adolescent offspring of probands with bipolar (BD), with non-BD psychiatric disorders, and health...

Study objectives:
The mechanisms linking short sleep duration to cardiovascular disease (CVD) are poorly understood. Emerging evidence suggests that endothelial dysregulation may lie along the causal pathway linking sleep duration to cardiovascular risk, although current evidence in humans is based on cross-sectional studies. Our objective was to...
Delgado-Gomez et al. (2016) have provided an interesting example of the comparison of computerized adaptive testing (CAT) based on unidimensional item response theory (IRT) and a machine learning approach based on decision trees (DT) in the prediction of people who have a history of suicide attempts. ... In the following we attempt to better articu...
Background
The diagnostic scheme for psychiatric disorders is currently based purely on descriptive nomenclature given that biomarkers subtypes and clearly defined causal mechanisms are lacking for the vast majority of disorders. The emerging field of “immuno-psychiatry” has the potential to widen the exploration of a mechanism-based nosology, poss...
We aim to close a methodological gap in analyzing durations of successive events that are subject to induced dependent censoring as well as competing-risk censoring. In the Bipolar Disorder Center for Pennsylvanians study, some patients who managed to recover from their symptomatic entry later developed a new depressive or manic episode. It is of g...
Study objective:
The neurobiological mechanisms of insomnia may involve altered patterns of activation across sleep-wake states in brain regions associated with cognition, self-referential processes, affect, and sleep-wake promotion. The objective of this study was to compare relative regional cerebral metabolic rate for glucose (rCMRglc) in these...
Background:
Individuals diagnosed with bipolar 1 disorder (BP1), bipolar 2 disorder (BP2), or major depressive disorder (MDD) experience varying levels of depressive and (hypo)manic symptoms. Clarifying symptom heterogeneity is meaningful, as even subthreshold symptoms may impact quality of life and treatment outcome. The MOODS Lifetime self-repor...
In this review we explore recent developments in computerized adaptive diagnostic screening and computerized adaptive testing for the presence and severity of mental health disorders such as depression, anxiety, and mania. The statistical methodology is unique in that it is based on multidimensional item response theory (severity) and random forest...

Electroencephalographic slow-wave activity (0.5–4 Hz) during non-rapid eye movement (NREM) sleep is a marker for cortical reorganization, particularly within the prefrontal cortex. Greater slow wave activity during sleep may promote greater waking prefrontal metabolic rate and, in turn, executive function. However, this process may be affected by a...
Objectives:
Disruptions in sleep and dysregulation in circadian functioning may represent core abnormalities in the pathophysiology of bipolar disorder (BP). However, it is not clear whether these dysfunctions are state or trait markers of BP. This report compared sleep and circadian phenotypes among three groups: offspring of parents with BP diag...
Objectives:
As outlined in the social zeitgeber hypothesis, social rhythm disrupting (SRD) life events begin a cascade of social and biological rhythm disruption that may lead to the onset of affective episodes in those vulnerable to bipolar disorder. Thus, the study of SRD events is particularly important in individuals with this chronic conditio...
Neuroscience based Nomenclature (NbN) is a new system of classifying psychotropic drugs by their pharmacological profile. The NbN was developed to replace the current indication-based nomenclature and to provide an up-to-date and more useful framework to better inform pharmacological decisions. NbN provides updated relevant and specific scientific,...
The DSM-5 process, and the publication of DSM-5 in 2013, have had a considerable impact on the classification of anxiety disorders. Major changes included the reorganization of the chapter structure, individual groupings of disorders within each chapter from a life span viewpoint, and the use of specifiers. The DSM-5 chapter on anxiety disorders do...
The need for innovative methods to promote training, advancement, and retention of clinical and translational investigators in order to build a pipeline of trainees to focus on mental health-relevant research careers is pressing.

Although bipolar disorder is increasingly recognised as a spectrum of multisystem disorders (ie, bipolar disorders), proposed staging models and theories of bipolar disease progression often fail to incorporate longitudinal data or data from multiple domains of dysfunction. We propose that bipolar disorders are best thought of as syndromes, with di...
Crohn's disease (CD) is associated with depression. It is unclear if psychosocial interventions offer benefit for depressive symptoms during active CD. In this secondary analysis of a larger study of treating depression in pediatric inflammatory bowel disease, we assessed whether cognitive behavioral therapy (CBT) would differentiate from supportiv...
Objective:
The authors sought to identify diagnostic risk factors of manic, mixed, or hypomanic episodes in the offspring of parents with bipolar disorder ("high-risk offspring").
Method:
High-risk offspring 6-18 years old (N=391) and demographically matched offspring (N=248) of community parents without bipolar disorder were assessed longitudin...
There is growing evidence that bipolar disorder (BD) is associated with inflammation, including abnormal levels of acute-phase C-reactive protein (CRP). Our meta-analysis was conducted to estimate the size of the association between CRP levels and BD, accounting also for subgroup differences (mood phases and treatment).

Objectives
Many of the first-line screening tools for obstructive sleep apnea (OSA) may not be accurate in patients with bipolar disorder due to confounding factors, such as chronic depressive symptoms, weight gain, and sedation due to medications. In the present study, we assessed the feasibility of in-home screening for sleep apnea in patients wi...
The authors describe a model for teaching grant writing and other research survival skills to postdoctoral clinical-research fellows in psychiatry and for improving research mentoring. Over the past 4 years, the authors have developed a course on writing grant applications for postdoctoral clinical-research fellows, using peer-review processes mode...
This review considers evidence that sleep and circadian rhythms are disturbed in bipolar patients during both mood episodes and periods of remission. Indeed, bipolar patients display disturbances of subjective and objective circadian markers, in sleep continuity, and in cortisol and melatonin secretion. Better characterization of sleep and circadia...
Psychiatric disorders have traditionally been classified using a static, categorical approach. However, this approach falls short in facilitating understanding of the development, common comorbid diagnoses, prognosis and treatment of these disorders. We propose a 'staging' model of bipolar disorder that integrates genetic and neural information wit...
Objective:
Pediatric inflammatory bowel disease (IBD) is associated with high rates of depression. This study compared the efficacy of cognitive behavioral therapy (CBT) to supportive nondirective therapy (SNDT) in treating youth with comorbid IBD and depression.
