Modifying Informed Consent to Help Address Functional Unmasking in Psychedelic Clinical Trials.

JAMA Psychiatry

January 2025

Department of Psychiatry and Behavioral Sciences, Weill Institute for Neurosciences, University of California, San Francisco.

Importance: There is unprecedented clinician, industry, and patient interest in the therapeutic development of psychedelic drugs. This is due to a combination of promising clinical trial results, positive media coverage, and the lack of novel pharmacologic treatments for psychiatric disorders in recent decades. However, the field faces a key methodological challenge: masking participants to treatment conditions in psychedelic clinical trials has been largely unsuccessful.

Background: Stopping or reducing risky or unneeded medications ("deprescribing") could improve older adults' health. Electronic health data can support observational and intervention studies of deprescribing, but there are no standardized measures for key variables, and healthcare systems have differing data types and availability. We developed definitions for chronic medication use and discontinuation based on electronic health data and applied them in a case study of benzodiazepines and Z-drugs in five diverse US healthcare systems.

Am J Geriatr Psychiatry

April 2024

Department of Psychiatry (SN, BN, CAM), University of Florida College of Medicine, Gainesville, FL; Center for OCD, Anxiety, and Related Disorders (COARD) (SN, BN, CAM), University of Florida, Gainesville, FL. Electronic address:

Hoarding disorder (HD) is a debilitating neuropsychiatric condition that affects 2%-6% of the population and increases in incidence with age. Major depressive disorder (MDD) co-occurs with HD in approximately 50% of cases and leads to increased functional impairment and disability. However, only one study to date has examined the rate and trajectory of hoarding symptoms in older individuals with a lifetime history of MDD, including those with current active depression (late-life depression; LLD).

Association of Uremic Solutes With Cardiovascular Death in Diabetic Kidney Disease.

Am J Kidney Dis

October 2022

Division of Nephrology, Department of Internal Medicine, MetroHealth Campus, School of Medicine, Case Western Reserve University, Cleveland, Ohio; Department of Physiology and Biophysics, School of Medicine, Case Western Reserve University, Cleveland, Ohio. Electronic address:

Rationale & Objective: Cardiovascular disease (CVD) is a major cause of mortality among people with diabetic kidney disease (DKD). The pathophysiology is inadequately explained by traditional CVD risk factors. The uremic solutes trimethylamine-N-oxide (TMAO) and asymmetric and symmetric dimethylarginine (ADMA, SDMA) have been linked to CVD in kidney failure with replacement therapy (KFRT), but data are limited in populations with diabetes and less severe kidney disease.

The Degree of Nesting between Spindles and Slow Oscillations Modulates Neural Synchrony.

J Neurosci

June 2020

Graduate Program in Bioengineering, University of California, Berkeley 94720, & University of California, San Francisco, California 94115

Spindles and slow oscillations (SOs) both appear to play an important role in memory consolidation. Spindle and SO "nesting," or the temporal overlap between the two events, is believed to modulate consolidation. However, the neurophysiological processes modified by nesting remain poorly understood.

It has been surprisingly difficult to find associations between neural signatures of schizophrenia and the symptoms that define it. That is, many of the legacy components of the event-related potential (ERP)- P50, N100, P200, P300-are reduced in patients with schizophrenia, in first-degree relatives of patients with schizophrenia, in schizophrenia patients early in their illness, and even in people at clinical high risk for schizophrenia. Nevertheless, these ERP components tend to be relatively insensitive to symptoms.

Imaging of flank pain: readdressing state-of-the-art.

Emerg Radiol

February 2017

Department of Radiology and Biomedical Imaging, University of California, San Francisco, 4150 Clement Street, Building 200, Rm 2A-166, San Francisco, CA, 94121, USA.

Pain resulting from renal and ureteral stones is a common cause for patients presenting in the acute setting. Since the late 1990s, computed tomography (CT) has been the initial imaging method of choice to evaluate patients with suspected ureteral stones; however, concerns regarding both radiation dose and cost-effectiveness have prompted investigations into a different imaging algorithm. Studies utilizing ultrasound have provided evidence indicating that it may be a more appropriate first step, with selective use of CT in selected cases, in the diagnostic work-up.
