How to Optimize Goal-Directed Medical Therapy (GDMT) in Patients with Heart Failure.

Purpose Of Review: Heart failure is a clinical syndrome with signs and symptoms from underlying cardiac abnormality and evidence of pulmonary or systemic congestion on laboratory testing or other objective findings (Bozkurt et al. in Eur J Heart Fail 23:352-380, 2021). Heart failure with reduced ejection fraction (HFrEF), when heart failure is due to underlying reduction in ejection fraction to 40.

The protective roles of coping self-efficacy and social support for posttraumatic stress during the COVID-19 pandemic.

Objective: This study examined the roles of social support and coping self-efficacy (CSE) in attenuating posttraumatic stress (PTS) symptoms during the COVID-19 pandemic among a nonclinical university student sample.

Method: Participants ( = 610; 59% female) completed questionaries assessing psychological distress (Kessler Psychological Distress Scale) at baseline and 6-month follow-up, and social support (Interpersonal Support Evaluation List-12), CSE Scale, and PTS symptoms (Impact of Event Scale-Revised) at 6 months. A path analysis was conducted using SPSS Amos to examine the direct and indirect pathways from psychological distress to PTS symptoms that are accounted for by social support and CSE, controlling for gender.

Late Right Heart Failure After Left Ventricular Assist Device Implantation: Contemporary Insights and Future Perspectives.

Late right heart failure (RHF) is increasingly recognized in patients with long-term left ventricular assist device (LVAD) support and is associated with decreased survival and increased incidence of adverse events such as gastrointestinal bleeding and stroke. Progression of right ventricular (RV) dysfunction to clinical syndrome of late RHF in patients supported with LVAD is dependent on the severity of pre-existing RV dysfunction, persistent or worsening left- or right-sided valvular heart disease, pulmonary hypertension, inadequate or excessive left ventricular unloading, and/or progression of the underlying cardiac disease. RHF likely represents a continuum of risk with early presentation and progression to late RHF.

Single-cell analysis of human nasal mucosal IgE antibody secreting cells reveals a newly minted phenotype.

Immunoglobulin (Ig) E is central to the pathogenesis of allergic conditions, including allergic fungal rhinosinusitis. However, little is known about IgE antibody secreting cells (ASCs). We performed single-cell RNA sequencing from cluster of differentiation (CD)19 and CD19 ASCs of nasal polyps from patients with allergic fungal rhinosinusitis (n = 3).

Reduced hepatocyte mitophagy is an early feature of NAFLD pathogenesis and hastens the onset of steatosis, inflammation and fibrosis.

Nonalcoholic fatty liver disease (NAFLD) encompasses a spectrum of pathologies that includes steatosis, steatohepatitis (NASH) and fibrosis and is strongly associated with insulin resistance and type 2 diabetes. Changes in mitochondrial function are implicated in the pathogenesis of NAFLD, particularly in the transition from steatosis to NASH. Mitophagy is a mitochondrial quality control mechanism that allows for the selective removal of damaged mitochondria from the cell via the autophagy pathway.

Total artificial heart implantation as a bridge to transplantation in the United States.

Objectives: Although the SynCardia total artificial heart (SynCardia Systems, LLC) was approved for use as a bridge to transplantation in 2004 in the United States, most centers do not adopt the total artificial heart as a standard bridging strategy for patients with biventricular failure. This study was designed to characterize the current use and outcomes of patients placed on total artificial heart support.

Methods: The United Network of Organ Sharing Standard Transplant Research File was queried to identify total artificial heart implantation in the United States between 2005 and 2018.

Psychological distress of college students during the COVID-19 pandemic.

Objectives To assess levels of psychological distress among a group of US undergraduate college students during the initial phases of the novel coronavirus (SARS-CoV-2) pandemic. All undergraduates at Kent State University were surveyed in three randomly selected cohorts on March 18, March 25, and April 1, yielding 3924 valid responses for the weighted dataset (73.8% female, 88.

Distress and Prevention Behaviors During the COVID-19 Pandemic Among College Students: the Moderating Role of Resilience.

Background: Pandemics can generate considerable distress, which can affect prevention behaviors. Resilience may buffer the negative effects of distress on engagement in relevant prevention behaviors, which may also hold true for COVID-19 prevention behaviors. The objective of the current study was to evaluate whether resilience moderated the relationship between distress and COVID-19 prevention behaviors early in the pandemic.

Evolutionary rate covariation identifies SLC30A9 (ZnT9) as a mitochondrial zinc transporter.

Recent advances in genome sequencing have led to the identification of new ion and metabolite transporters, many of which have not been characterized. Due to the variety of subcellular localizations, cargo and transport mechanisms, such characterization is a daunting task, and predictive approaches focused on the functional context of transporters are very much needed. Here we present a case for identifying a transporter localization using evolutionary rate covariation (ERC), a computational approach based on pairwise correlations of amino acid sequence evolutionary rates across the mammalian phylogeny.

Structural and functional cardiac changes in endomyocardial fibrosis treated with endomyocardial resection: Disease progression captured by multimodality imaging.

Eosinophilic myocarditis, a rare and under-recognized disease process, occurs due to cytotoxic inflammation of the endomyocardium that over time may lead to a restrictive cardiomyopathy. We report clinical, multimodality imaging, and pathologic findings in a 45-year-old woman over a 17-month period as she progressed from suspected acute eosinophilic myocarditis to phenotypic endomyocardial fibrosis resulting in recurrent ascites. Interval echocardiograms demonstrate definitive pathologic structural changes that reflect the hemodynamic consequences of the underlying cardiomyopathy.

Ileal Derived Organoids From Crohn's Disease Patients Show Unique Transcriptomic and Secretomic Signatures.

Background & Aims: We used patient-derived organoids (PDOs) to study the epithelial-specific transcriptional and secretome signatures of the ileum during Crohn's disease (CD) with varying phenotypes to screen for disease profiles and potential druggable targets.

Methods: RNA sequencing was performed on isolated intestinal crypts and 3-week-old PDOs derived from ileal biopsies of CD patients (n = 8 B1, inflammatory; n = 8 B2, stricturing disease) and non-inflammatory bowel disease (IBD) controls (n = 13). Differentially expressed (DE) genes were identified by comparing CD vs control, B1 vs B2, and inflamed vs non-inflamed.

RIP3-dependent necroptosis contributes to the pathogenesis of chronic obstructive pulmonary disease.

Necroptosis has emerged as a potential mechanism in the pathogenesis of chronic obstructive pulmonary disease (COPD). Here, we found that markers of necroptosis, including high mobility group box 1 release and phosphorylation of mixed lineage kinase domain-like protein (p-MLKL), were markedly induced in the late stage of cigarette smoking-induced (CS-induced) emphysema in mouse lung tissue as well as in lung epithelial cells and organoids with higher dosage of or more prolonged exposure to cigarette smoking extract (CSE). Apoptotic signals were also detected and maximally induced in the early stage of CS-exposed mice and CSE-treated epithelial cells.

Using Ligand-Accelerated Catalysis to Repurpose Fluorogenic Reactions for Platinum or Copper.

The development of a fluorescent probe for a specific metal has required exquisite design, synthesis, and optimization of fluorogenic molecules endowed with chelating moieties with heteroatoms. These probes are generally chelation- or reactivity-based. Catalysis-based fluorescent probes have the potential to be more sensitive; however, catalytic methods with a biocompatible fluorescence turn-on switch are rare.

A long non-coding RNA GATA6-AS1 adjacent to GATA6 is required for cardiomyocyte differentiation from human pluripotent stem cells.

Long noncoding RNAs (lncRNAs) are crucial in many cellular processes, yet relatively few have been shown to regulate human cardiomyocyte differentiation. Here, we demonstrate an essential role of GATA6 antisense RNA 1 (GATA6-AS1) in cardiomyocyte differentiation from human pluripotent stem cells (hPSCs). GATA6-AS1 is adjacent to cardiac transcription factor GATA6.

COVID-19 in recent heart transplant recipients: Clinicopathologic features and early outcomes.

Background: The impact of COVID-19 on heart transplant (HTx) recipients remains unclear, particularly in the early post-transplant period.

Methods: We share novel insights from our experience in five HTx patients with COVID-19 (three within 2 months post-transplant) from our institution at the epicenter of the pandemic.

Results: All five exhibited moderate (requiring hospitalization, n = 3) or severe (requiring ICU and/or mechanical ventilation, n = 2) illness.

Targeting HIF-1α in combination with PPARα activation and postnatal factors promotes the metabolic maturation of human induced pluripotent stem cell-derived cardiomyocytes.

Immature phenotypes of cardiomyocytes derived from human induced pluripotent stem cells (hiPSC-CMs) limit the utility of these cells in clinical application and basic research. During cardiac development, postnatal cardiomyocytes experience high oxygen tension along with a concomitant downregulation of hypoxia-inducible factor 1α (HIF-1α), leading to increased fatty acid oxidation (FAO). We hypothesized that targeting HIF-1α alone or in combination with other metabolic regulators could promote the metabolic maturation of hiPSC-CMs.

Assessing the Geographic Context of Risk Perception and Behavioral Response to Potential Ebola Exposure.

The 2014⁻2016 Ebola Virus Disease (EVD) epidemic outbreak reached over 28,000 cases and totaled over 11,000 deaths with 4 confirmed cases in the United States, which sparked widespread public concern about nationwide spread of EVD. Concern was elevated in locations connected to the infected people, which included Kent State University in Kent, Ohio. This threat of exposure enabled a unique opportunity to assess self-reported knowledge about EVD, risk perception, and behavior response to EVD.

Meso-scale topological cues influence extracellular matrix production in a large deformation, elastomeric scaffold model.

Physical cues are decisive factors in extracellular matrix (ECM) formation and elaboration. Their transduction across scale lengths is an inherently symbiotic phenomenon that while influencing ECM fate is also mediated by the ECM structure itself. This study investigates the possibility of enhancing ECM elaboration by topological cues that, while not modifying the substrate macro scale mechanics, can affect the meso-scale strain range acting on cells incorporated within the scaffold.

Quantitative and qualitative assessment of glymphatic flux using Evans blue albumin.

Background: The glymphatic system is a proposed pathway for clearance of proteins and macromolecules from brain, and disrupted glymphatic flux is implicated in neurological disease. We capitalized on colorimetric, fluorescent, and protein-binding properties of Evans blue to evaluate glymphatic flux.

New Method: Twenty-five μL of 1% Evans blue-labeled albumin (EBA) in artificial cerebrospinal fluid (aCSF) was injected into the intracisternal space of anesthetized postnatal day 17 rats.

Free Chlorine Disinfection of Full-Scale MBR Effluent to Achieve 5-Log Virus Inactivation.

  A series of full-scale testing was performed at the City of Lathrop Consolidated Treatment Facility to determine the "concentration times time" (Ct) value for free chlorine disinfection of nitrified membrane bioreactor (MBR) effluent to achieve more than 5-log virus inactivation. The full-scale testing consisted of tracer study, chlorine decay study, and virus seeding study. The virus seeding study was performed at a flow rate of 1 million gal/d (3800 m3/min), which corresponded to a theoretical contact time of 117 minutes in the chlorine contact basin.
