The liver possesses a unique regenerative capacity, driven by mechanisms that extend beyond classical growth factor signaling. Recent studies underscore the importance of metabolic reprogramming, mitochondrial adaptation, and signaling metabolites in promoting tissue injury repair. Dynamic crosstalk between hepatocytes, non-parenchymal cells, and other organs governs the regenerative process. Spatial compartmentalization within the liver and systemic cues from adipose tissue, the pancreas, the gut, the brain, skeletal muscle, and other organs play critical roles in shaping regenerative outcomes. In this review we discuss how the liver's tissue microenvironment and inter-organ communication networks regulate liver regeneration, providing new insights into the complex …

Chronic lung allograft dysfunction (CLAD) limits long-term lung graft survival, yet its specific gene expression profiles remain unclear. We performed comprehensive spatial transcriptomic analyses of human lungs from CLAD patients, non-CLAD transplant recipients, and non-transplanted controls. In CLAD, AP-1 target genes, including JUNB and FOS, were significantly upregulated in both the epithelium and endothelium, whereas anti-fibrotic genes such as A2M and surfactant proteins (SFTPA1,2) were upregulated in non-CLAD. The lymphocyte population in CLAD was predominantly composed of T cells, with elevated JAK3-IL7R signaling. TNF and IL-17 signaling pathways were commonly activated in both the epithelium and endothelium, with JUNB and …

Over the past 15 years, genetic studies of psychiatric disorders have provided important insight into the contribution of both common variants of small effect, as well as rare exonic and copy number variants with large effect sizes. Genome-wide association studies (GWAS) allow us to understand the intricate polygenicity characteristic of many psychiatric disorders. However, a considerable proportion of single nucleotide polymorphisms (SNPs) implicated in these disorders localize to the non-coding regions of the genome. Unraveling the molecular mechanisms that underlie the etiology of psychiatric illnesses requires integration using functional genomics approaches. Functional genomics methods are critical for developing a mechanistic …

Consciousness is a fundamental component of cognition1, but the degree to which higher-order pattern recognition relies on it remains disputed2,3. Here we demonstrate the persistence of oddball discrimination, semantic processing and online prediction in individuals under general-anaesthesia-induced loss of consciousness4,5. Using high-density Neuropixels microelectrodes6 to record both single-unit and local-field-potential neural activity in the human hippocampus while playing a series of tones to anaesthetized patients, we found that hippocampal neurons and local oscillations retained some detection of oddball tones. This effect size grew over the course of the experiment …

Treatment Of Obsessive-Compulsive Disorder Via Mental Health Technology, Erika S Trent, Nisha Jagannathan, Eric A Storch

Faculty, Staff and Students Publications

Obsessive-compulsive disorder (OCD) is a debilitating neuropsychiatric disorder that remains chronic unless intervened with evidence-based intervention. Cognitive behavioral therapy (CBT) with exposure and response prevention is the gold-standard psychological intervention for OCD, but many individuals do not receive this intervention due to barriers to accessing treatment. Mental health technology tools such as telehealth, computerized programs, internet-delivered CBT, and mobile applications have been adopted to expand the accessibility of CBT. An up-to-date summary of the evidence base of technology-mediated formats of CBT for OCD treatment is provided. Clinical benefits offered by such approaches, current limitations, and future research directions are discussed.

Faculty, Staff and Students Publications

Medicare beneficiaries frequently visit the emergency department (ED) at the end of life, but little is known about the epidemiology of patients admitted to hospice from the ED. We used 100 percent Medicare fee-for-service claims from the period 2018-20 to describe the frequency of direct ED-to-hospice enrollments, associated patient and hospice agency characteristics, and patient outcomes. In this sample, 4.3 percent of initial enrollments in hospice originated from the ED. ED-to-hospice admissions featured short lengths-of-stay (21.7 percent were two days or less) and high rates of general inpatient level of care at the time of enrollment (23.6 percent). The 10 …

How To … Coach Problem Representation To Strengthen Diagnostic Reasoning In Trainees, Cody Clary, Adam Cohen, Satid Thammasitboon

Faculty, Staff and Students Publications

Problem representation (PR) is a concise synthesis of clinical information that captures the core diagnostic problem in a single statement, often referred to as a 'one-liner'. Although central to diagnostic reasoning, this skill is frequently underdeveloped in medical training. Many trainees struggle to transform clinical data into meaningful representations, which can hinder communication, diagnostic reasoning and patient safety. The Assessment of Reasoning Tool-Reconstructed (ART-R) provides a structured framework that educators can adapt as a coaching rubric to strengthen PR during clinical teaching. Using the ART-R, faculty can guide trainees to refine their PR by focusing on three elements: (1) clarity …

Non-Isolated Dandy-Walker Malformation: Exome Sequencing Efficacy And Phenotypic Expansions, Sarah Araji, Xiaonan Zhao, Jill A Rosenfeld, Seema R Lalani, Daryl A Scott

Faculty, Staff and Students Publications

Dandy-Walker malformation (DWM) is a rare congenital abnormality of the posterior fossa and the cerebellum and has an incidence of 1 in 10 000 to 30 000 births. Although DWM can present in isolation, it is often associated with other central nervous system (CNS) abnormalities or extra-CNS anomalies (DWM+). A molecular cause is not identified in the majority of individuals with DWM+. This is due, in part, to uncertainty regarding optimal testing strategies and an incomplete understanding of the genetic causes of DWM+. In this study, we analyzed clinical exome sequencing (cES) data from 91 individuals with DWM+ to determine …

Smaller Right Ventricle Results In Poorer Exercise Performance In Young Patients With Repaired Tetralogy Of Fallot, Christiane Mhanna, Katerina Kourpas, Takeshi Tsuda

Department of Pediatrics Faculty Papers

BACKGROUND: Severe right ventricular (RV) dilatation and exercise intolerance are considered indications for pulmonary valve replacement in surgically repaired tetralogy of Fallot (rTOF).

METHODS AND RESULTS: Cardiopulmonary exercise testing (CPET) and cardiac magnetic resonance (CMR) were performed in rTOF patients with pulmonary insufficiency (PI). Oxygen pulse (OP), calculated as oxygen consumption (V̇O

CONCLUSIONS: A smaller RV was associated with worse exercise performance, indicating exercise intolerance is independent of RV dilatation in young rTOF with PI and represents a unique pathological entity responsible for reduced exercise performance.
