Brain Stimulation Therapeutic Interventions in Neuropsychiatry: A Cambrian Explosion

Brain stimulation interventions alter neural activity by applying electrical, magnetic, sonic, or other forms of energy to the nervous system, using invasive or noninvasive methods. In recent years, the basic science and clinical science of neuromodulation have markedly advanced,...

Perceptions of Incidental Findings on Lung Cancer Screening Exams: A National Survey of Primary Care Clinicians and Radiologists

RATIONALE: Unlike other common cancer screenings, annual lung cancer screening often identifies a spectrum of incidental findings unrelated to lung cancer. While these findings could be actionable, how to best communicate and manage them can be a challenge, often falling upon pri...

Radiology considerations for the PREMIUM study: a multicenter randomized controlled trial of abbreviated MRI versus ultrasound for liver cancer screening in cirrhosis

Abstract This paper describes the rationale and radiology considerations in the implementation of the Preventing Liver Cancer Mortality through Imaging with Ultrasound versus MRI (PREMIUM) study. PREMIUM is a multicenter, randomized controlled trial sponsored by the Department of...

Baroreflex Activation Therapy in Patients with Heart Failure with a Reduced Ejection Fraction.

A randomized, controlled trial of baroreflex activation therapy (BAT) in patients with heart failure and reduced ejection fraction demonstrated that BAT was safe and significantly improved patient-centered symptomatic outcomes, increasing exercise capacity, improving quality of l...

Probing the neurochemical mechanisms of rTMS for alcohol use disorder: Results from a randomized, sham-controlled, double-blind, crossover, proton MR Spectroscopy study

Abstract With growing knowledge of the neural circuitry involved in alcohol use disorder (AUD), interest in developing neural-circuit-based therapeutic tools, including transcranial magnetic stimulation (TMS), for people with AUD has increased. While mounting evidence supports th...

Impact of Medical Treatment on Nasal Discharge in Chronic Rhinosinusitis: A Systematic Review and Meta-Analysis

Background One of the defining symptoms of chronic rhinosinusitis is nasal discharge. There are multiple treatment options, and the relative efficacy of each medication on discharge is unclear. Objective To characterize the effects of medical treatment on the various forms of nas...

Timing and Duration of Prediabetic Metabolic Dysfunction Differentially Impact Cerebral Perfusion, Vascular Structure, and Behavior

Abstract Obesity is a major risk factor for metabolic dysfunction and cognitive decline, yet the influence of age of onset and sex on neurovascular outcomes remains unclear. We examined how the age at initiation and duration of diet-induced obesity influence metabolism, cognition...

Impaired but now diagnosable: Combining analytic frameworks for incorporating symptom weighting in the classification of full‐threshold and subthreshold posttraumatic stress disorder

Abstract Individuals with subthreshold posttraumatic stress disorder (PTSD) often experience significant impairment yet face barriers to care (e.g., insurance denials and exclusion from clinical trials) due to strict Diagnostic and Statistical Manual of Mental Disorders ( DSM )–b...

RAS inhibition limits oncogenic signaling and tumorigenesis in neuroblastoma regardless of RAS mutational status

Abstract Neuroblastoma (NBL) is a rare and aggressive pediatric malignancy with a 5-year survival rate of 40–50% for patients diagnosed with high-risk disease. NBLs arise in the sympathetic nervous system and causes 11% of all pediatric cancer deaths. MYCN amplification or overex...
