Objective: While emerging evidence suggests that electroconvulsive therapy (ECT) is an effective treatment for depressive symptoms in patients with co-occurring borderline personality disorder (BPD) traits, it is unclear whether the presence of BPD traits modulates the tolerability of ECT. This study estimates the association between BPD traits and retention in acute course ECT treatment.

Methods: This study used a retrospective cohort of patients receiving ECT between 2015 and 2020 and who were assessed using the McLean Screening Instrument for BPD, the Quick Inventory of Depressive Symptomatology Self-Report 16-item scale, and the Montreal Cognitive Assessment before initiating treatment.

Background: Researchers are increasingly investigating therapeutic response associated with new patient subgroups as a way to improve electroconvulsive therapy (ECT) treatment outcomes and reduce adverse events. This study is the first to examine baseline cognitive impairment status as a predictor of clinical outcome in first acute-course ECT patients.

Methods: Baseline cognitive function at various thresholds and serial depressive symptom severity data from first-time ECT patients were examined using generalized linear mixed-effects models.

Community mental health centers (CMHCs) provide the majority of mental health services for low-income individuals in the United States. Exposure and response prevention (ERP), the psychotherapy of choice for obsessive-compulsive disorder (OCD), is rarely delivered in CMHCs. This study aimed to establish the acceptability and feasibility of testing a behavioral therapy team (BTT) intervention to deliver ERP in CMHCs.

Background: Electroconvulsive therapy (ECT) is the gold-standard treatment for refractory depression. Borderline personality disorder (BPD) is generally considered a poor predictor of treatment response. We sought to assess symptom-severity outcomes among depressed patients with (BPD+) and without (BPD-) comorbid BPD undergoing acute phase ECT.

Comorbid personality disorders are common in patients with major depressive disorder (MDD). Individuals with comorbid borderline personality disorder (BPD) may be less responsive to electroconvulsive therapy (ECT), but it remains unclear whether BPD affects responsiveness to transcranial magnetic stimulation (TMS). We sought to investigate the association between BPD and response to TMS.

A first episode of psychosis (FEP) can derail a patient's educational goals, including attainment of a college education, and this can have lasting ramifications for socioeconomic and health outcomes. Despite this, few studies have examined return to college, which is an important index of real-world educational success after a FEP. In this study, we conducted a longitudinal medical record review of patients in a transdiagnostic outpatient FEP program and performed survival analysis, setting return to college as the endpoint, among the subset of patients whose college education was interrupted.

Background: Standard clinical protocols for repetitive transcranial magnetic stimulation (rTMS) for major depressive disorder (MDD) apply 10 Hz pulses over left prefrontal cortex, yet little is known about the effects of rTMS in more diagnostically complex depressed patients.

Objective/hypothesis: Posttraumatic stress disorder (PTSD) is commonly comorbid with MDD, and while rTMS has been shown to alleviate PTSD symptoms in preliminary studies, ideal parameters remain unclear. We conducted a prospective, open-label study of 5 Hz rTMS for patients with comorbid PTSD + MDD and hypothesized stimulation would reduce symptoms of both disorders.

Objective: The purpose of the current study was to conduct a randomized controlled trial testing the efficacy of aerobic exercise for decreasing OCD symptom severity, other mental health outcomes, and increasing exercise behaviors and cardiorespiratory fitness among individuals with OCD.

Method: Fifty-six patients (64% female; mean age=38.8years) with OCD and a Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score of 16 or greater despite engaging in OCD treatment were randomized to 12-weeks of supervised plus home-based moderate-intensity aerobic exercise (AE; n=28) or to 12-weeks of health education sessions (HE; n=28).

Background: Repetitive transcranial magnetic stimulation (TMS) has been shown to be safe and effective for treatment-resistant depression (TRD) in the general adult population. Efficacy among older (≥60 years) patients, who have a greater burden of cognitive, physical, and functional impairment compared to their younger counterparts, remains unclear. The current study aimed to characterize antidepressant response to an acute course of TMS therapy among patients aged ≥60 years compared to those <60 years in naturalistic clinical practice settings.

Objective: Few data are available to inform clinical expectations about course and prognosis of severe obsessive-compulsive disorder (OCD). Such information is necessary to guide clinicians and to inform criteria for invasive interventions for severe and intractable OCD. This study sought to examine course and prospective predictors of a chronic course in patients with severe OCD over 5 years.

Dysfunction in circuits linking frontal cortex and basal ganglia (BG) is strongly implicated in obsessive-compulsive disorder (OCD). On MRI studies, neuropsychiatric disorders with known BG pathology have abnormally short T2 relaxation values (a putative biomarker of elevated iron) in this region. We asked if BG T2 values are abnormal in OCD.

Background: To find specific genes predisposing to heavy alcohol consumption (self-reported consumption of 24 grams or more of alcohol per day among men and 12 grams or more among women), we studied 330 families collected by the Framingham Heart Study made available to participants in the Genetic Analysis Workshop 13 (GAW13).

Results: Parametric and nonparametric methods of linkage analysis were used. No significant evidence of linkage was found; however, weak signals were identified in several chromosomal regions, including 1p22, 4q12, 4q25, and 11q24, which are in the vicinity of those reported in other similar studies.

Background: Atherogenic dyslipidemia (AD) is a common feature in persons with premature coronary heart disease. While several linkage studies have been carried out to dissect the genetic etiology of lipid levels, few have investigated the AD lipid triad comprising elevated serum triglyceride, small low density lipoprotein (LDL) particles, and reduced high density lipoprotein (HDL) cholesterol levels. Here we report the results of a whole-genome screen for AD using the Framingham Heart Study population.

Background: The Framingham Heart Study has contributed a great deal to advances in medicine. Most of the phenotypes investigated have been univariate traits (quantitative or qualitative). The aims of this study are to derive multivariate traits by identifying homogeneous groups of people and assigning both qualitative and quantitative trait scores; to assess the heritability of the derived traits; and to conduct both qualitative and quantitative linkage analysis on one of the heritable traits.
