The impact of sex on pathophysiological processes, clinical presentation, treatment options, as well as outcomes of degenerative aortic stenosis remain poorly understood. Female patients are well represented in transfemoral aortic valve implantation (TAVI) trials and appear to derive favorable outcomes with TAVI. However, higher incidences of major bleeding, vascular complications, and stroke have been reported in women following TAVI. The anatomical characteristics and pathophysiological features of aortic stenosis in women might guide a tailored planning of the percutaneous approach. We highlight whether a sex-based TAVI management strategy might impact on clinical outcomes. This review aimed to evaluate the impact of …

Platelets are anucleate cells that mediate hemostasis. This occurs via a primary signal that is reinforced by secreted products such as ADP that bind purinergic receptors (P2Y1 and P2Y12) on the platelet surface. We recently identified a human subject, whom we termed platelet defect subject 25 (PDS25) with a platelet functional disorder associated with the P2Y12 receptor. PDS25 has normal blood cell counts and no history of bleeding diathesis. However, platelets from PDS25 have virtually no response to 2-MeSADP (a stable analogue of ADP). Genetic analysis of P2Y12 from PDS25 revealed a heterozygous mutation of D121N within the DRY motif. …

Despite therapeutic interventions for glioblastoma (GBM), cancer stem cells (CSCs) drive recurrence. The precise mechanisms underlying CSC resistance, namely inhibition of cell death, are unclear. We built on previous observations that the high cell surface expression of junctional adhesion molecule-A drives CSC maintenance and identified downstream signaling networks, including the cysteine protease inhibitor SerpinB3. Using genetic depletion approaches, we found that SerpinB3 is necessary for CSC maintenance, survival, and tumor growth, as well as CSC pathway activation. Knockdown of SerpinB3 also increased apoptosis and susceptibility to radiation therapy. SerpinB3 was essential to buffer cathepsin L-mediated cell death, which was enhanced …

Selpercatinib is a first-in-class, highly selective and potent, central nervous system-active RET kinase inhibitor. In the phase I/II trial, selpercatinib demonstrated clinically meaningful antitumor activity with manageable toxicity in heavily pre-treated and treatment-naive patients with RET-mutant medullary thyroid cancer (MTC). LIBRETTO-531 (NCT04211337) is a multicenter, open-label, randomized, controlled, phase III trial comparing selpercatinib to cabozantinib or vandetanib in patients with advanced/metastatic RET-mutant MTC. The primary objective is to compare progression-free survival (per RECIST 1.1) by blinded independent central review of patients with progressive, advanced, multikinase inhibitor-naive, RET-mutant MTC treated with selpercatinib versus cabozantinib or vandetanib. …

The critical role of G protein-coupled receptor kinase 2 (GRK2) in regulating cardiac function has been well documented for >3 decades. Targeting GRK2 has therefore been extensively studied as a novel approach to treating cardiovascular disease. However, little is known about its role in hemostasis and thrombosis. We provide here the first evidence that GRK2 limits platelet activation and regulates the hemostatic response to injury. Deletion of GRK2 in mouse platelets causes increased platelet accumulation after laser-induced injury in the cremaster muscle arterioles, shortens tail bleeding time, and enhances thrombosis in adenosine 5'-diphosphate (ADP)-induced pulmonary thromboembolism and in FeCl3-induced carotid …
Predictive Factors And Outcomes For Ibrutinib In Relapsed/Refractory Marginal Zone Lymphoma: A Multicenter Cohort Study, Narendranath Epperla, Qiuhong Zhao, Sayan Mullick Chowdhury, Lauren Shea, Tamara K Moyo, Nishitha Reddy, Julia Sheets, David M Weiner, Praveen Ramakrishnan Geethakumari, Malathi Kandarpa, Ximena Jordan Bruno, Colin Thomas, Michael C Churnetski, Andrew Hsu, Luke Zurbriggen, Cherie Tan, Kathryn Lindsey, Joseph Maakaron, Paolo F Caimi, Pallawi Torka, Celeste Bello, Sabarish Ayyappan, Reem Karmali, Seo-Hyun Kim, Anna Kress, Shalin Kothari, Yazeed Sawalha, Beth Christian, Kevin A David, Irl Brian Greenwell, Murali Janakiram, Vaishalee P Kenkre, Adam J Olszewski, Jonathon B Cohen, Neil D.

Ibrutinib is effective in the treatment of relapsed/refractory (R/R) marginal zone lymphoma (MZL) with an overall response rate (ORR) of 48%. However, factors associated with response (or lack thereof) to ibrutinib in R/R MZL in clinical practice are largely unknown. To answer this question, we performed a multicenter (25 US centers) cohort study and divided the study population into three groups: "ibrutinib responders"-patients who achieved complete or partial response (CR/PR) to ibrutinib; "stable disease (SD)"; and "primary progressors (PP)"-patients with progression of disease as their best response to ibrutinib. One hundred and nineteen patients met the eligibility criteria with 58%/17% …

Half The Picture: Word Frequencies Reveal Racial Differences In Clinical Documentation, But Not Their Causes, Jacqueline A Penn, Denis Newman-Griffis
Department of Medicine Faculty Papers
Clinical notes are the best record of a provider's perceptions of their patients, but their use in studying racial bias in clinical documentation has typically been limited to manual evaluation of small datasets. We investigated the use of computational methods to scale these insights to large, heterogeneous clinical text data. We found significant differences in negative emotional tone and language implying social dominance in clinical notes between Black and White patients, but identified multiple contributing factors in addition to potential provider bias, including mis-categorization of some healthcare vocabulary as emotion-related. We further found that notes for Black patients were significantly …

Pseudoxanthoma elasticum (PXE) and generalized arterial calcification of infancy (GACI) are clinically distinct genetic entities of ectopic calcification associated with differentially reduced circulating levels of inorganic pyrophosphate (PPi), a potent endogenous inhibitor of calcification. Variants in ENPP1, the gene mutated in GACI, have not been associated with classic PXE. Here we report the clinical, laboratory, and molecular evaluations of ten GACI and two PXE patients from five and two unrelated families registered in GACI Global and PXE International databases, respectively. All patients were found to carry biallelic variants in ENPP1. Among ten ENPP1 variants, one homozygous variant demonstrated uniparental disomy …

Background: When it comes to scheduling interviews, medical students may wonder if they need a strategy to increase their likelihood of matching. Previous studies examined the temporal effects of the residency interview on overall match rate; however, there are additional factors that affect the match process, including board examination scores and letters of recommendation. Only few studies have examined the effect interview time of day has on match success. The current study examines the impact date and time of interview during the interview season have on candidates' respective interview scores.
Methods: Interview data over a three-year period (i.e., three interview …

Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver and is a leading cause of mortality worldwide. While there are many risk factors for HCC including alcohol, obesity, and diabetes, hepatitis B virus (HBV) and hepatitis C virus (HCV) infection still account for the majority of HCC worldwide. Globally, HBV is the leading risk factor for HCC. Patients with chronic hepatitis B (CHB) and advanced liver disease are at high risk for HCC. Screening for HCC is done routinely with ultrasound with or without alpha-fetoprotein (AFP) at six-month intervals. The combination of ultrasound and AFP has been …

Baroreflex Sensitivity In Facioscapulohumeral Muscular Dystrophy, Miguel Anselmo, Shandon Coffman, Mia Larson, Kathryn Vera, Emma Lee, Mary Mcconville, Michael Kyba, Manda L Keller-Ross
Department of Medicine Faculty Papers
Facioscapulohumeral muscular dystrophy (FSHD), a common form of muscular dystrophy, is caused by a genetic mutation that alters DUX4 gene expression. This mutation contributes to significant skeletal muscle loss. Although it is suggested that cardiac muscle may be spared, people with FSHD have demonstrated autonomic dysregulation. It is unknown if baroreflex function, an important regulator of blood pressure (BP), is impaired in people with FSHD. We examined if baroreflex sensitivity (BRS) is blunted in patients with FSHD. Thirty minutes of resting BP, heart rate, and cardiovagal BRS were measured in 13 patients with FSHD (age: 50 ± 13 years, avg …

Hepatitis B Virus-Associated Hepatocellular Carcinoma And Chronic Stress, Nicholas Noverati, Rukaiya Bashir, Dina Halegoua-De Marzio, Hie-Won Hann
Department of Medicine Faculty Papers
The Hepatitis B virus is one of the most significant hepatocarcinogens globally. The carcinogenic mechanisms of this virus are complex, and may include interactions with the host's immune system. Certain factors, such as stress on the body, can also potentiate these mechanisms. Stress, although adaptive in an acute form, is deleterious to health when chronic and can both suppress and activate the host's defense system. In hepatocellular carcinoma, this can lead to tumor initiation and progression. Those that are more prone to stress, or exposed to situations that incite stress, may be at higher risk of developing cancer. Racial disparities, …

Transitions Of Care: Completeness Of The Interoperability Data Standard For Communication From Home Health Care To Primary Care., Edgar Chou, Paulina S Sockolow
Department of Medicine Faculty Papers
Data sharing is necessary to address communication deficits along the transitions of care among community settings. Evidence-based practice supports home healthcare (HHC) patients to see their primary care team within the first two weeks of hospital discharge to reduce rehospitalization risk. A small subset of patient data collected at HHC admission is mandated to be transmitted to primary care, predominantly by fax. Using qualitative analysis, we assessed completeness of the United States Core Data for Interoperability (USCDI) interoperability standard, as compared to the patient data collected by the primary care team (topics) and HHC (classes) during the initial visit; and …

Department of Medicine Faculty Papers
Összefoglaló. A malignus daganatok és a stroke együttesen gyakran fordulnak elő a stroke tradicionális rizikófaktoraival (magas vérnyomás, hyperlipidaemia, cukorbetegség, elhízás, dohányzás) rendelkező betegekben. Az elmúlt évtized kutatási eredményei alátámasztották, hogy a rosszindulatú daganatban szenvedő betegekben szignifikánsan nagyobb a stroke kockázata. A malignus daganatokhoz társuló stroke a leggyakrabban a malignus daganat diagnózisát követő fél-egy év során jelentkezik. A kapcsolat a másik irányban is létezik: stroke-betegek követése során malignus daganat szignifikánsan gyakrabban jelent meg, mint a stroke-mentes kontrollcsoportban. A daganatot a leginkább a stroke utáni első hat hónapban diagnosztizálják. A korábban nem ismert rosszindulatú daganat időnként az akut stroke kezelése során derül …

Heparin-induced thrombocytopenia (HIT) is associated with severe and potentially lethal thrombotic complications. NETosis was recently shown to be an important driver of thrombosis in HIT. We investigated the role of reactive oxygen species (ROS) and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 2 (NOX2) and their contributions to thrombus development in HIT. We showed that neutrophil activation by HIT immune complexes induced ROS-dependent NETosis. Analysis of thrombi formed in a microfluidics system showed ROS production in both platelets and neutrophils, and abundant neutrophil extracellular traps (NETs) and ROS distributed throughout the clot. Neutrophil-targeted ROS inhibition was sufficient to block HIT-induced NETosis …

Department of Medicine Faculty Papers
Coronavirus disease 2019 (COVID-19) has rapidly become a worldwide pandemic ushering in a global health and economic crisis. In the absence of vaccines or definitive drug therapies, current strategies against COVID-19 rely on preventing the transmission of disease through nonpharmaceutical interventions such as social distancing and proper hand hygiene. For practical and perhaps ethical reasons, the clinical efficacy of these public health measures for managing pandemics has not been demonstrated in randomized controlled clinical trials. Accordingly, guideline recommendations for using nonpharmaceutical interventions are based primarily on observational and modeling studies and on expert opinion. A recent position paper from the …

Along with cancer, cardiovascular and cerebrovascular diseases remain by far the most common causes of death. Heart attacks and strokes are diseases in which platelets play a role, through activation on ruptured plaques and subsequent thrombus formation. Most platelet agonists activate platelets via G protein-coupled receptors (GPCRs), which make these receptors ideal targets for many antiplatelet drugs. However, little is known about the mechanisms that provide feedback regulation on GPCRs to limit platelet activation. Emerging evidence from our group and others strongly suggests that GPCR kinases (GRKs) are critical negative regulators during platelet activation and thrombus formation. In this review, …

PURPOSE: To report the medium to long-term safety and performance outcomes of the KeraKlear nonpenetrating artificial cornea (KeraKlear) as the primary procedure in patients with corneal blindness due to noninflammatory anterior cornea disease.
METHODS: Fifteen patients with corneal blindness (preoperative visual acuity [VA] of ≥20/200) due to a non-inflammatory anterior corneal condition were included in this prospective, single-center study. Preoperative diagnoses included corneal scars, keratoconus, and corneal dystrophies. Diseased corneas were implanted with the KeraKlear (KeraMed Inc., Irvine, California, USA) by a single surgeon (JMV) using a femtosecond laser to create all incisions. Participants were followed up with for as …
