Facilitating Smoking Cessation in Primary Care Settings.

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.

Increasing COVID-19 Vaccination Rates Among Patients With Serious Mental Illness: A Pilot Intervention Study.

Objective: This pilot project aimed to maximize COVID-19 vaccine uptake among patients with serious mental illness. Psychiatric providers were engaged to directly address COVID-19 vaccine-related concerns with patients during outpatient visits.

Methods: A quality improvement project encouraged COVID-19 vaccinations in a cohort of outpatients treated with clozapine (N=193, ages 19-81 years, mean age=46.

Alpha-synuclein pathology, microgliosis, and parvalbumin neuron loss in the amygdala associated with enhanced fear in the Thy1-aSyn model of Parkinson's disease.

In Parkinson's disease (PD), the second most common neurodegenerative disorder, non-motor symptoms often precede the development of debilitating motor symptoms and present a severe impact on the quality of life. Lewy bodies containing misfolded α-synuclein progressively develop in neurons throughout the peripheral and central nervous system, which may be correlated with the early development of non-motor symptoms. Among those, increased fear and anxiety is frequent in PD and thought to result from pathology outside the dopaminergic system, which has been the focus of symptomatic treatment to alleviate motor symptoms.

Feasibility and Acceptability of a Collaborative Lung Cancer Screening Educational Intervention Tailored for Individuals With Serious Mental Illness.

Purpose: Individuals with serious mental illness (SMI) experience disparities in lung cancer mortality. Using a two-phase, mixed-methods approach, we developed a person-centered lung cancer screening (LCS) educational intervention (phase 1) for individuals with SMI (schizophrenia and bipolar disorder) and evaluated acceptability, feasibility, and changes in attitudes toward LCS (phase 2).

Methods: Phase 1: We conducted three focus groups with mental health, primary care, and radiology clinicians and utilized rapid qualitative analysis to adapt the LCS intervention (LCS walk-through video and smoking cessation handouts) tailored for individuals with SMI.

Wilson Disease: An Overview and Approach to Management.

Wilson's disease is one of the few preventable movement disorders in which there are therapies that modify disease progression. This disease is caused by copper overload caused by reduced copper excretion secondary to genetic mutations in the ATP7B gene. Copper overload can lead to a variety of clinical presentations, including neurologic symptoms, liver failure, and/or psychiatric manifestations.

Education Research: Evaluation of curriculum to teach resilience skills to neurology residents.

Objective: To evaluate feasibility and acceptability of a health professional resilience skills training program with neurology residents.

Methods: The curriculum consists of five 1-hour-long modules that included the following skills: reflective narrative practices, emotion regulation, communication with highly distressed individuals, boundary management, and the identification of depression and trauma. Using a web-based survey tool, we administered the Brief Resilience Scale (BRS) and Abbreviated Maslach Burnout Inventory (aMBI) at baseline, in addition to a pre- and post-survey assessing change in beliefs and self-efficacy, as well as satisfaction with the intervention.

A GCase chaperone improves motor function in a mouse model of synucleinopathy.

Mutation of the lysosomal hydrolase acid-β-glucosidase (GCase), which leads to reduced GCase activity, is one of the most frequent genetic risk factors for Parkinson's disease (PD) and promotes α-synuclein accumulation in the brain, a hallmark of PD and other synucleinopathies. Whether targeting GCase pharmacologically is a valid therapeutic strategy for sporadic PD in the absence of GCase mutation is unknown. We have investigated whether increasing the stability, trafficking, and activity of wild-type GCase could be beneficial in synucleinopathies by administering the pharmacological chaperone AT2101 (afegostat-tartrate, isofagomine) to mice that overexpress human wild-type α-synuclein (Thy1-aSyn mice).

Chronic administration of cholesterol oximes in mice increases transcription of cytoprotective genes and improves transcriptome alterations induced by alpha-synuclein overexpression in nigrostriatal dopaminergic neurons.

Cholesterol-oximes TRO19622 and TRO40303 target outer mitochondrial membrane proteins and have beneficial effects in preclinical models of neurodegenerative diseases leading to their advancement to clinical trials. Dopaminergic neurons degenerate in Parkinson's disease (PD) and are prone to oxidative stress and mitochondrial dysfunction. In order to provide insights into the neuroprotective potential of TRO19622 and TRO40303 for dopaminergic neurons in vivo, we assessed their effects on gene expression in laser captured nigrostriatal dopaminergic neurons of wildtype mice and of mice that over-express alpha-synuclein, a protein involved in both familial and sporadic forms of PD (Thy1-aSyn mice).

Incidence and behavioral correlates of epileptiform abnormalities in autism spectrum disorders.

Autism spectrum disorders (ASD) are associated with an increased incidence of epilepsy and of epileptiform discharges on electroencephalograms. It is unknown whether epileptiform discharges correlate with symptoms of ASD. We completed a retrospective chart review of 101 patients with ASD who had overnight electroencephalograms.

A pilot trial of the microtubule-interacting peptide (NAP) in mice overexpressing alpha-synuclein shows improvement in motor function and reduction of alpha-synuclein inclusions.

Abnormal accumulation of α-synuclein is associated with several neurodegenerative disorders (synucleinopathies), including sporadic Parkinson's disease (PD). Genetic mutations and multiplication of α-synuclein cause familial forms of PD and polymorphisms in the α-synuclein gene are associated with PD risk. Overexpression of α-synuclein can impair essential functions within the cell such as microtubule-dependent transport, suggesting that compounds that act on the microtubule system may have therapeutic benefit for synucleinopathies.

Olfactory deficits in mice overexpressing human wildtype alpha-synuclein.

Accumulation of alpha-synuclein in neurons of the central and peripheral nervous system is a hallmark of sporadic Parkinson's disease (PD) and mutations that increase alpha-synuclein levels cause familial PD. Transgenic mice overexpressing alpha-synuclein under the Thy1 promoter (Thy1-aSyn) have high levels of alpha-synuclein expression throughout the brain but no loss of nigrostriatal dopamine neurons up to 8 months, suggesting that they may be useful to model pre-clinical stages of PD. Olfactory dysfunction often precedes the onset of the cardinal motor symptoms of PD by several years and includes deficits in odor detection, discrimination and identification.
