Association of age at depression onset with cognitive functioning in individuals with late-life depression and executive dysfunction
To compare patterns of cognitive performance in older adults with late-onset depression (LOD; ≥65 years of age) with that of older adults with early-onset depression (EOD; <65 years).

Early adult to midlife cardiovascular risk factors and cognitive function
Studies have linked midlife and late-life cardiovascular risk factors (CVRFs) to cognitive function, yet little is known about CVRF exposure in early adulthood and subsequent cognitive function. In addition, most studies rely on single assessments of CVRFs, which may not accurately reflect long-term exposure. We sought to determine the association between cumulative exposure to CVRFs from early to middle adulthood and cognitive function at midlife.

Psychiatric Disorders: Diagnosis to Therapy
Recent findings in genetics and genomics, neurobiology, cognitive neuroscience, neuroimaging, and pharmacology are presenting an accelerating array of challenges to the conventional wisdom regarding the etiology, classification, and treatment of psychiatric conditions and forcing a reappraisal of research methods and approaches.

Efficacy of adjunctive aripiprazole in patients with major depressive disorder whose symptoms worsened with antidepressant monotherapy
Efficacy of depression treatments, including adjunctive antipsychotic treatment, has not been explored for patients with worsening symptoms after antidepressant therapy (ADT).

Substance use and drinking outcomes in Personalized Cognitive Counseling randomized trial for episodic substance-using men who have sex with men
Non-dependent alcohol and substance use patterns are prevalent among men who have sex with men (MSM), yet few effective interventions to reduce their substance use are available for these men. We evaluated whether an adapted brief counseling intervention aimed at reducing HIV risk behavior was associated with secondary benefits of reducing substance use among episodic substance-using MSM (SUMSM).

Chronicity of posttraumatic stress disorder and risk of disability in older persons
Little is known about the association between posttraumatic stress disorder (PTSD) and disability into later life. Most studies of late-life psychiatric disorders and function have focused on depression and generalized anxiety disorder.

A multi-scanner study of subcortical brain volume abnormalities in schizophrenia
Schizophrenia patients show significant subcortical brain abnormalities. We examined these abnormalities using automated image analysis software and provide effect size estimates for prospective multi-scanner schizophrenia studies.

Modafinil augments oscillatory power in middle frequencies during rule selection
Control-related cognitive processes are associated with cortical oscillations and modulated by catecholamine neurotransmitters. It remains unclear how catecholamine systems modulate control-related oscillations. We tested modafinil effects on rule-related 4-30 Hz oscillations, with double-blind, placebo-controlled (within-subjects) testing of 22 healthy adults, using EEG during cognitive control task performance.

Spiritual AIM and the work of the chaplain: a model for assessing spiritual needs and outcomes in relationship
Distinguishing the unique contributions and roles of chaplains as members of healthcare teams requires the fundamental step of articulating and critically evaluating conceptual models that guide practice. However, there is a paucity of well-described spiritual assessment models. Even fewer of the extant models prescribe interventions and describe desired outcomes corresponding to spiritual assessments.

Mindfulness-based cognitive therapy (MBCT) versus the health-enhancement program (HEP) for adults with treatment-resistant depression: a randomized study
Major depressive disorder (MDD) is the leading cause of disability in the developed world, yet broadly effective treatments remain elusive. Up to 40% of patients with depression are unresponsive to at least two trials of antidepressant medication and thus have "treatment-resistant depression" (TRD). There is an urgent need for cost-effective, non-pharmacologic, evidence-based treatments for TRD. Mindfulness-Based Cognitive Therapy (MBCT) is an effective treatment for relapse prevention and residual depression in major depression, but has not been previously studied in patients with TRD in a large randomized trial.

Visual hallucinations are associated with hyperconnectivity between the amygdala and visual cortex in people with a diagnosis of schizophrenia
While auditory verbal hallucinations (AH) are a cardinal symptom of schizophrenia, people with a diagnosis of schizophrenia (SZ) may also experience visual hallucinations (VH). In a retrospective analysis of a large sample of SZ and healthy controls (HC) studied as part of the functional magnetic resonance imaging (fMRI) Biomedical Informatics Research Network (FBIRN), we asked if SZ who endorsed experiencing VH during clinical interviews had greater connectivity between visual cortex and limbic structures than SZ who did not endorse experiencing VH.

Glutamate and choline levels predict individual differences in reading ability in emergent readers
Reading disability is a brain-based difficulty in acquiring fluent reading skills that affects significant numbers of children. Although neuroanatomical and neurofunctional networks involved in typical and atypical reading are increasingly well characterized, the underlying neurochemical bases of individual differences in reading development are virtually unknown.

Recent challenges to the psychiatric diagnostic nosology: a focus on the genetics and genomics of neurodevelopmental disorders
Recent advances in the genetics of neurodevelopmental disorder (NDD) have demonstrated that rare mutations play a role not only in Mendelian syndromes, but in complex, common forms of NDDs as well.

Multiple conserved regulatory domains promote Fezf2 expression in the developing cerebral cortex
The genetic programs required for development of the cerebral cortex are under intense investigation. However, non-coding DNA elements that control the expression of developmentally important genes remain poorly defined. Here we investigate the regulation of Fezf2, a transcription factor that is necessary for the generation of deep-layer cortical projection neurons.

A variant of sparse partial least squares for variable selection and data exploration
When data are sparse and/or predictors multicollinear, current implementation of sparse partial least squares (SPLS) does not give estimates for non-selected predictors nor provide a measure of inference. In response, an approach termed "all-possible" SPLS is proposed, which fits a SPLS model for all tuning parameter values across a set grid.

Functions of non-suicidal self-injury in adolescents and young adults with Borderline Personality Disorder symptoms
Rates of deliberate non-suicidal self-injury (NSSI) increase during adolescence and young adulthood, particularly in clinical samples, making these important developmental stages for understanding the functions of NSSI. Borderline Personality Disorder (BPD) symptoms also begin to emerge in adolescence, though little research has examined relationships between BPD symptoms and the functions of NSSI in youth, the primary goal of the present study.
