CPT Pharmacometrics Syst Pharmacol

January 2025

Division of Clinical Pharmacology, Department of Pediatrics, Spencer Fox Eccles School of Medicine, University of Utah, Salt Lake City, Utah, USA.

Sotalol, a class III antiarrhythmic agent, is used to maintain sinus rhythm in patients with atrial fibrillation or atrial flutter (AFIB/AFL). Despite its efficacy, sotalol's use is limited by its potential to cause life-threatening ventricular arrhythmias due to QT interval prolongation. Traditionally, sotalol administration required hospitalization to monitor these risks.

On the Limits of Anonymization for Promoting Diversity in Organizations.

Pers Soc Psychol Bull

January 2025

Negotiation, Organizations & Markets Unit, Harvard Business School, Harvard University, Boston, Massachusetts.

Anonymization of job applicant resumes is a recommended strategy to increase diversity in organizations, but large-scale tests have shown mixed results. We consider decision-makers' social dominance orientation (SDO), a measure of anti-egalitarianism/endorsement of group-based hierarchy, to illustrate the limits of anonymization. Across four pre-registered studies ( = 3,150), we show that (a) lower SDO individuals are less likely to hire individuals from underrepresented groups when job materials are anonymized and (b) they are more likely to opt into using anonymization.

Background: Genetic testing has traditionally been divided into molecular genetics and cytogenetics, originally driven by the use of different assays and their associated limitations. Cytogenetic technologies such as karyotyping, fluorescent in situ hybridization or chromosomal microarrays are used to detect large "megabase level" copy number variants and other structural variants such as inversions or translocations. In contrast, molecular methodologies are heavily biased toward subgenic "small variants" such as single nucleotide variants, insertions/deletions, and targeted detection of intragenic, exon level deletions or duplications.

Racial, Socioeconomic, and Geographic Disparities in Preamputation Vascular Care for Patients With Chronic Limb-Threatening Ischemia.

Circ Cardiovasc Qual Outcomes

January 2025

Penn Cardiovascular Outcomes, Quality, and Evaluative Research Center, Perelman School of Medicine, University of Pennsylvania, Philadelphia. (L.Y., K.S., E.G., S.M.D., G.J.W., A.S.N., L.A.E., H.M.J., T.J.K., P.W.G., J.G., A.C.F.).

Background: Black patients, those with low socioeconomic status (SES), and those living in rural areas have elevated rates of major lower extremity amputation, which may be related to a lack of subspecialty chronic limb-threatening ischemia care. We evaluated the association between race, rurality, SES, and preamputation vascular care.

Methods: Among patients aged 66 to 86 years with fee-for-service Medicare who underwent major lower extremity amputation for chronic limb-threatening ischemia from July 2010 to December 2019, we compared the proportion who received vascular care in the 12 months before amputation by race (Black versus White), rurality, and SES (dual eligibility for Medicaid versus no dual eligibility) using multivariable logistic regression adjusting for clinical and demographic covariates.

Front Immunol

January 2025

Department of Basic and Translational Sciences, School of Dental Medicine, University of Pennsylvania, Philadelphia, PA, United States.

Introduction: A subtype of human mast cells (MCs) found in the skin and to a lesser extent in the lung and gut express a novel G protein-coupled receptor (GPCR) known as Mas-related GPCR-X2 (MRGPRX2, mouse counterpart MrgprB2). In addition to drug-induced pseudoallergy and cutaneous disorders, MrgprB2 contributes to ulcerative colitis, IgE-mediated lung inflammation and systemic anaphylaxis. Interestingly, most agonists activate MRGPRX2 with higher potency than MrgprB2.

The ability to adapt to changing circumstances has strong survival value. Individuals with substance use disorders tend to get "stuck" over-responding to drug-reward signals and pursuing drugs despite negative consequences. A lack of flexibility may be tied to impairments in neurocognition, including learning, memory, and executive function.

Unlabelled: The Alzheimer's disease (AD) research field has entered a new era, where our fundamental understanding of the pathophysiology of AD and advances in biomarkers have not only allowed for earlier, timely, and accurate detection and diagnosis of the disease, but that amyloid removal has been shown to be associated with signals of slowing cognitive and functional decline. Although recent FDA-approved amyloid plaque-lowering monoclonal antibody therapies have shifted the trajectory of AD, additional treatment options will be key to further slowing clinical decline or stopping disease progression. Thus, new and emerging therapies for AD have created an evolving therapeutic landscape.
