Obsessive compulsive disorder (OCD) has an increased prevalence throughout pregnancy and in the postpartum period relative to non-peripartum periods. While some obsessive-compulsive symptoms in this period present in the same manner to those in non-postpartum OCD, others are more specific to the postpartum period (e.g., obsessions related to sudden infant death syndrome [SIDS]). However, there are few validated scales assessing obsessive-compulsive symptoms during the postpartum period. This study examined the psychometric properties of the Postpartum Thoughts and Behaviors Checklist (PTBC), a semi-structured interview of intrusive thoughts and repetitive, neutralizing behaviors developed to address this gap. In a sample of 257 …

Background and aims: Enhanced inflammatory signalling causally contributes to atrial fibrillation (AF) development. Gasdermin D (GSDMD) is an important downstream effector of several inflammasome pathways. However, the role of GSDMD, particularly the cleaved N-terminal (NT)-GSDMD, in non-immune cells remains elusive. This study aimed to elucidate the function of NT-GSDMD in atrial cardiomyocytes (ACMs) and determine its contribution to atrial arrhythmogenesis.

Methods: Human atrial appendages were used to assess the protein levels and localization. A modified adeno-associated virus 9 was employed to establish ACM-restricted overexpression of NT-GSDMD in mice.

Results: The cleavage of GSDMD was enhanced in ACMs of AF patients. …

Hypertriglyceridemia (HTG), particularly in combined hyperlipidemia, increases risk for atherosclerotic cardiovascular disease, but the underlying mechanisms remain incompletely understood. We sought to determine contributions of circulating monocytes to atherosclerosis associated with HTG in combined hyperlipidemia, created by transgenic expression of human apoCIII in Ldlr−/− mice (Ldlr−/−ApoCIIItg) fed Western high-fat diet (WD). Tissue culture with THP-1 and primary human monocytes was used to examine effects of triglyceride (TG)-rich lipoproteins on monocytes. Ldlr−/−ApoCIIItg mice were also treated with apoCIII antisense oligonucleotide (ASO) and examined for foamy monocytes and atherosclerosis. Compared to Ldlr−/− mice, Ldlr−/−ApoCIIItg mice fed …

Patients with undiagnosed and/or rare disorders frequently manifest dysmorphic and neurological features. There is a lack of information on the effectiveness of telehealth in the evaluation of these disorders. We thus compared an unassisted virtual physical examination (PE) with an in-person PE in undiagnosed individuals and also assessed participant telehealth satisfaction. Twenty-six individuals enrolled in the Undiagnosed Diseases Network study underwent an in-home synchronous virtual PE, and a subsequent in-person PE, by the same clinician. The participants completed surveys on telehealth usability and provider empathy. On PE, general appearance and craniofacial features showed near perfect agreement (κ = 0.81-1.00) between …

Faculty, Staff and Students Publications

Objectives: There is limited knowledge on how providers and patients in the emergency department (ED) use electronic health records (EHRs) to facilitate the diagnostic process. While EHRs can support diagnostic decision-making, EHR features that are not user-centered may increase the likelihood of diagnostic error. We aimed to identify how EHRs facilitate or impede the diagnostic process in the ED and to identify opportunities to reduce diagnostic errors and improve care quality.

Materials and methods: We conducted semistructured interviews with 10 physicians, 15 nurses, and 8 patients across 4 EDs. Data were analyzed using a hybrid thematic analysis approach, which blends …

Background: Curative responses to immunotherapy require the generation of robust systemic immunity with limited toxicity. Recruitment of T cell populations such as precursor exhausted T cells (Tpex) from lymphoid tissues to tumors is a hallmark of effective treatment. However, the ability to efficiently induce this recruitment is lacking in current immunotherapy approaches. Furthermore, systemic administration of immunotherapies frequently results in dose-limiting toxicities, yielding an inadequate therapeutic window for eliciting durable responses.

Methods: In this investigation, we evaluated the safety and antitumor efficacy of locally administered interleukin 12 (IL-12) using a clinically translatable cytokine delivery platform (NCT05538624) to identify …

DNA damage promotes mutations that fuel cancer, aging, and neurodegenerative diseases1–3, but surprisingly, the causes and types of damage remain largely unknown. There are three identified mechanisms that damage DNA during transcription: RNA polymerase (RNAP) colliding with DNA-replication machinery head-on and co-directionally4–6, and R-loop-induced DNA breakage7–10. Here, we identify DNA-damage reaction intermediates11,12 uncharacterized previously in living cells, and uncover a surprising fourth transcription-related source: endogenous DNA damage at sites of terminated transcripts. We engineered proteins to capture single-stranded (ss)DNA ends with 3'-polarity, in both bacterial …

MEF2C is a critical transcription factor in neurodevelopment, whose loss-of-function mutation in humans results in MEF2C haploinsufficiency syndrome (MHS), a severe form of autism spectrum disorder (ASD)/intellectual disability (ID). Despite prior animal studies of MEF2C heterozygosity to mimic MHS, MHS-specific mutations have not been investigated previously, particularly in a human context as hiPSCs afford. Here, for the first time, we use patient hiPSC-derived cerebrocortical neurons and cerebral organoids to characterize MHS deficits. Unexpectedly, we found that decreased neurogenesis was accompanied by activation of a micro-(mi)RNA-mediated gliogenesis pathway. We also demonstrate network-level hyperexcitability in MHS neurons, as evidenced by excessive synaptic …

Despite major advancements in heart failure (HF) management and guideline recommendations over the past two decades, real-world evidence highlights suboptimal implementation of guideline-directed medical therapy (GDMT) for HF with reduced ejection fraction (HFrEF). Low blood pressure (BP) is common in HFrEF patients and represents a major perceived barrier to implementing life-saving treatments in clinical practice, as physicians are often concerned about symptomatic hypotension and its consequences. Although low BP can be seen in those hospitalized with signs of shock, the most common scenario involves non-severe, asymptomatic hypotension in patients receiving foundational therapy for HFrEF, where premature down-titration or discontinuation of …
