Early Detection Of Amniotic Fluid Embolism Leading To Extracorporeal Membrane Oxygenation Prior To Cardiac Arrest, Enad Haddad, Hamza Muhammadzai, Shayan Iqbal Khan, Angad Bedi, Rajesh Patel

Abington Jefferson Health Papers

Amniotic fluid embolism is a life-threatening peripartum condition with high morbidity and mortality rates. It is defined as the passage of fetal material into the maternal circulation which elicits a multisystem reaction that can lead to disseminated intravascular coagulopathy and severe hemodynamic instability. Despite established diagnostic criteria for amniotic fluid embolism, its identification relies heavily on clinical judgment, and early diagnosis is key to patient survival. In several cases, early utilization of extracorporeal membrane oxygenation support has provided a salvage approach to correct cardiopulmonary collapse. Herein, we present a case of successful application of venoarterial extracorporeal membrane oxygenation in a …

Predicting Kidney Graft Function And Failure Among Kidney Transplant Recipients, Yi Yao, Brad C Astor, Wei Yang, Tom Greene, Liang Li

Faculty, Staff and Student Publications

Background: Graft loss is a major health concern for kidney transplant (KTx) recipients. It is of clinical interest to develop a prognostic model for both graft function, quantified by estimated glomerular filtration rate (eGFR), and the risk of graft failure. Additionally, the model should be dynamic in the sense that it adapts to accumulating longitudinal information, including time-varying at-risk population, predictor-outcome association, and clinical history. Finally, the model should also properly account for the competing risk by death with a functioning graft. A model with the features above is not yet available in the literature and is the focus of …

Implications Of Myocardial Strain In Primary Mitral Regurgitation-A Cardiovascular Magnetic Resonance Study, Simone Romano, Danai Kitkungvan, Duc T Nguyen, Carlos El-Tallawi, Edward A Graviss, Afshin Farzaneh-Far, Dipan J Shah

Faculty, Staff and Student Publications

Aims: Chronic primary mitral regurgitation (MR) results in progressive left ventricular (LV) remodelling. Abnormal myocardial deformation (strain) can be present despite preserved ejection fraction (EF). Cardiovascular magnetic resonance (CMR) feature-tracking techniques allow assessment of global longitudinal strain (GLS) from routine cine images. The aim of this study is to evaluate the prognostic value of CMR feature tracking-derived GLS in patients with primary MR.

Methods and results: Consecutive patients undergoing CMR for chronic MR from January 2012 to June 2018 were enrolled. Patients with LVEF < 50% were excluded. The composite primary outcome aiming to detect decompensation related to MR comprised (i) referral for mitral surgery owing to symptoms or LV systolic dysfunction or (ii) cardiovascular death. The secondary outcome was all-cause death. A total of 422 patients were followed for a median of 2.7 years, and the primary endpoint was met in 93 patients (34 patients reported symptoms at baseline). At multivariable analysis, GLS≥ -16.6% was associated with primary outcome [hazard ratio (HR) 1.90, P = 0.01]. In moderate MR cohort, patients with GLS≥ -16.6% had worse event-free survival, whereas there was no significant difference in mild or severe MR groups. GLS≥ -16.0% remained associated with all-cause death after adjusting for other covariates including the MR severity (HR 2.24, P = 0.02).

Conclusion: In patients with primary MR with preserved systolic function, GLS was associated with our composite …

Abington Jefferson Health Papers

Among viral myocarditis, human metapneumovirus (hMPV) is a rare causative agent with associated cardiac complications. This report provides insight into the disease progression and sheds light on reported cases from the literature. We present the clinical courses of two patients, aged 68 and 58, who developed myocarditis secondary to hMPV infection. Despite the typical severity associated with viral myocarditis in older populations, both patients experienced significant improvement in their condition and ultimately survived. This report highlights the necessity of recognizing hMPV as a potential cause of myocarditis, particularly in older adults presenting with simultaneous respiratory and cardiac symptoms. The recovery …

Potential Of Right Ventricular Function Assessment With Echocardiography In Transcatheter Aortic Valve Replacement, Yoshihisa Morita, Taro Kariya, Michael Dougherty, Andrew Peters, Nicholas Ruggiero

Division of Cardiology Faculty Papers

BACKGROUND: Right ventricular (RV) function assessment by echocardiography can be challenging due to its complex morphology. Also, increasing use of sedation rather than general anesthesia for transfemoral approach transcatheter aortic valve replacement (TAVR) reduces the need for intraoperative transesophageal echocardiography (TEE). Recent clinical studies have demonstrated the importance of 3-dimensional (3D) echocardiography and a longitudinal strain for RV function assessment. In this study, we compared RV function echocardiographic assessment methodologies in TAVR and investigated its clinical utility.

METHODS: This was a prospective, observational study of TAVR at a large academic hospital. Inclusion criteria were adult patients undergoing TAVR requiring intraoperative …

2020-Current year OA Pubs

E-cigarette/vaping-associated lung injury (EVALI) is strongly associated with vitamin E acetate and often occurs with concomitant tetrahydrocannabinol (THC) use. To uncover pathways associated with EVALI, we examined cytokines, transcriptomic signatures, and lipidomic profiles in bronchoalveolar lavage fluid (BALF) from THC-EVALI patients. At a single center, we prospectively enrolled mechanically ventilated patients with EVALI from THC-containing products (N = 4) and patients with non-vaping acute lung injury and airway controls (N = 5). BALF samples were analyzed by Luminex multiplex assay, RNA sequencing, and mass spectrometry. After treating BEAS-2B lung epithelial cells with vaping and non-vaping BALF, LDH release was quantified. …

Surgical Delay-Associated Mortality Risk Varies By Subtype In Loco-Regional Breast Cancer Patients In Seer-Medicare, Macall Leslie Salewon, Rashmi Pathak, William Dooley, Ronald Squires, Hallgeir Rui, Inna Chervoneva, Takemi Tanaka

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Substantial evidence supports that delay of surgery after breast cancer diagnosis is associated with increased mortality risk, leading to the introduction of a new Commission on Cancer quality measure for receipt of surgery within 60 days of diagnosis for non-neoadjuvant patients. Breast cancer subtype is a critical prognostic factor and determines treatment options; however, it remains unknown whether surgical delay-associated breast cancer-specific mortality (BCSM) risk differs by subtype. This retrospective cohort study aimed to assess whether the impact of delayed surgery on survival varies by subtype (hormone [HR] + /HER2 -, HR -/HER2 -, and HER2 +) in patients with …

Metaplastic breast cancer (MpBC) is a highly chemoresistant subtype of breast cancer with no standardized therapy options. A clinical study in anthracycline-refractory MpBC patients suggested that nitric oxide synthase (NOS) inhibitor NG-monomethyl-l-arginine (L-NMMA) may augment anti-tumor efficacy of taxane. We report that NOS blockade potentiated response of human MpBC cell lines and tumors to phosphoinositide 3-kinase (PI3K) inhibitor alpelisib and taxane. Mechanistically, NOS blockade leads to a decrease in the S-nitrosylation of c-Jun NH

Eight (12%) transitioned back to intravenous antifungal therapy, one due to perceived treatment failure defined by clinical progression or worsening. Global treatment response at study completion was successful in 66 participants who transitioned to enteral therapy.

Age-Dependent Regulation Of Axoglial Interactions And Behavior By Oligodendrocyte Ankyring, Xiaoyun Ding, Yu Wu, Anna Vainshtein, Victoria Rodriguez, Emily Ricco, James T Okoh, Yanhong Liu, Daniel C Kraushaar, Elior Peles, Matthew N Rasband

Faculty, Staff and Students Publications

The bipolar disorder (BD) risk gene ANK3 encodes the scaffolding protein AnkyrinG (AnkG). In neurons, AnkG regulates polarity and ion channel clustering at axon initial segments and nodes of Ranvier. Disruption of neuronal AnkG causes BD-like phenotypes in mice. During development, AnkG is also expressed at comparable levels in oligodendrocytes and facilitates the efficient assembly of paranodal junctions. However, the physiological roles of glial AnkG in the mature nervous system, and its contributions to BD-like phenotypes, remain unexplored. Here, we show that oligodendroglia-specific AnkG conditional knockout results in destabilization of axoglial interactions in aged but not young adult mice. In …

Carboxyl Ester Lipase Hybrid 1 (Cel-Hyb1) Haplotypes Confer Varying Risk For Chronic Pancreatitis, Gergő Berke, Xunjun K Xiao, Mark E Lowe, Et Al.

2020-Current year OA Pubs

The CEL-HYB1 hybrid allele of the carboxyl ester lipase (CEL) gene and its pseudogene (CELP) has been associated with chronic pancreatitis (CP). Recent work indicated that amino acid positions 488 and 548 in CEL-HYB1 determined pathogenicity. Haplotype Thr488-Ile548 was associated with CP while haplotypes Thr488-Thr548 and Ile488-Thr548 were benign. However, functional analysis revealed that Thr488 is the primary determinant of CEL-HYB1 misfolding and associated endoplasmic reticulum (ER) stress. To address this contradiction, we analyzed a cohort from Hungary and found significantly increased CEL-HYB1 carrier frequency in CP cases (9/319, 2.8%) versus controls (5/618, 0.8%), yielding an odds ratio of 3.6 …

Refinement Of An Algorithm To Detect And Predict Freezing Of Gait In Parkinson Disease Using Wearable Sensors, Allison M Haussler, Lauren E Tueth, David S May, Gammon M Earhart, Pietro Mazzoni

2020-Current year OA Pubs

Freezing of gait (FOG) is a debilitating symptom of Parkinson disease (PD). It is episodic and variable in nature, making assessment difficult. Wearable sensors used in conjunction with specialized algorithms, such as our group's pFOG algorithm, provide objective data to better understand this phenomenon. While these methods are effective at detecting FOG retrospectively, more work is needed. The purpose of this paper is to explore how the existing pFOG algorithm can be refined to improve the detection and prediction of FOG. To accomplish this goal, previously collected data were utilized to assess the prediction ability of the current algorithm, the …

Aggressive breast cancers often fail or acquire resistance to radiotherapy. To develop new strategies to improve the outcome of aggressive breast cancer patients, we studied how PARP inhibition radiosensitizes breast cancer models to proton therapy, which is a radiotherapy modality that generates more DNA damage in the tumor than standard radiotherapy using photons. Two human BRCA1-mutated breast cancer cell lines and their isogenic BRCA1-recovered pairs were treated with a PARP inhibitor and irradiated with photons or protons. Protons (9.9 and 3.85 keV/µm) induced higher cell kill independent of BRCA1 status. PARP inhibition amplified the cell kill effect to both photons …

Alteration of responses to salient stimuli occurs in a wide range of brain disorders and may be rooted in pathophysiological brain state dynamics. Specifically, tonic and phasic modes of activity in the reticular activating system (RAS) influence, and are influenced by, salient stimuli, respectively. The RAS influences the spectral characteristics of activity in the neocortex, shifting the balance between low- and high-frequency fluctuations. Aperiodic '1/f slope' has emerged as a promising composite measure of these brain state dynamics. However, the relationship of 1/f slope to state-dependent processes, such as saliency, is less explored, particularly intracranially in humans. Here, we record …

Background: Breast cancer is the most prevalent cancer among women worldwide. Most breast cancer-related deaths result from metastasis and drug resistance. Novel therapies are imperative for targeting metastatic and drug-resistant breast cancer cells. Accumulating evidence suggests that dysregulated microRNAs (miRNAs) promote breast cancer progression, metastasis, and drug resistance. Compared with healthy breast tissue, miR-660-5p is notably overexpressed in breast cancer tumor tissues. However, the downstream effectors of miR-660-5p in breast cancer cells have not been fully elucidated. Our aim was to investigate the role of miR-660-5p in breast cancer cell proliferation, migration, invasion, and angiogenesis and to identify its potential …
