Transseptal Balloon-Assisted Translocation of Mitral Leaflet for Mitral Calcification: A First in Human Experience.

We present a first in human experience of transseptal balloon-assisted translocation of a mitral anterior leaflet (BATMAN) to facilitate transcatheter mitral valve replacement in a patient with severe mitral annular calcification who was at high risk of left ventricular outflow tract obstruction.

The Impact of Attentiveness Interventions on Survey Data.

Social and behavioral science researchers who use survey data are vigilant about data quality, with an increasing emphasis on avoiding common method variance (CMV) and insufficient effort responding (IER). Each of these errors can inflate and deflate substantive relationships, and there are both a priori and post hoc means to address them. Yet, little research has investigated how both IER and CMV are affected with the use of these different procedural or statistical techniques used to address them.

Discriminatory power of trabeculectomy bleb internal reflectivity and morphology in surgical success using anterior segment optical coherence tomography.

Background: The post-operative evaluation of trabeculectomy blebs has traditionally relied on subjective clinical grading systems performed at the slit-lamp. This study explores the use of swept source anterior-segment optical coherence tomography (AS-OCT) to objectively measure bleb internal reflectivity and morphology, and to distinguish blebs with surgical success vs. failure.

Rhesus Cytomegalovirus-encoded Fcγ-binding glycoproteins facilitate viral evasion from IgG-mediated humoral immunity.

Human cytomegalovirus (HCMV) encodes four viral Fc-gamma receptors (vFcγRs) that counteract antibody-mediated activation in vitro, but their role in infection and pathogenesis is unknown. To examine their in vivo function in an animal model evolutionarily closely related to humans, we identified and characterized Rh05, Rh152/151 and Rh173 as the complete set of vFcγRs encoded by rhesus CMV (RhCMV). Each one of these proteins displays functional similarities to their prospective HCMV orthologs with respect to antagonizing host FcγR activation in vitro.

Comparative efficacy and safety of stent retrievers as a bailout strategy following failed contact aspiration technique in acute stroke thrombectomy.

Background: The contact aspiration (CA) technique is often used to perform endovascular thrombectomy (EVT) for acute ischemic stroke (AIS); however, rescue strategies are necessary if CA fails to achieve recanalization. This study investigates the outcomes of incorporating stent retriever (SR) thrombectomy in the rescue strategy following failed CA.

Methods: EVT patients with failed CA attempts were identified from a large multicenter registry and stratified by rescue technique: CA alone or incorporating SR in the rescue strategy.

Environmentally persistent free radicals stimulate CYP2E1-mediated generation of reactive oxygen species at the expense of substrate metabolism.

Environmentally persistent free radicals (EPFRs) are a recently recognized component of particulate matter that cause respiratory and cardiovascular toxicity. The mechanism of EPFR toxicity appears to be related to their ability to generate reactive oxygen species (ROS), causing oxidative damage. EPFRs were shown to affect cytochrome P450 (P450) function, inducing the expression of some forms through the Ah receptor.

Revised Process for ACNS Guidelines Development.

The development of clinical practice guidelines is an evolving field. In response to the need for consistent, evidence-based medical practice, the American Clinical Neurophysiology Society identified the need to update the Society's guideline development process. The American Clinical Neurophysiology Society Guidelines Committee created an action plan with the goal of improving transparency and rigor for future guidelines and bringing existing guidelines to current standards.

Identifying At-Risk Populations for Reoperations, Readmissions, and Interventions in MBSAQIP Using a Novel Inpatient Postoperative Care Metric.

Introduction: Metabolic and bariatric surgery (MBS) is increasingly used for obesity and metabolic disease, with safety profiles showing it is among the safest major operations. The last 20 + years have noted significantly improved safety that has been accompanied by decreasing length of stay and select populations electing for outpatient surgery, leading to continued decreases in cost. Regardless, readmissions and complications still occur, requiring inpatient postoperative care (IP-POC).

Recent Findings: INOCA/MINOCA has a complex pathophysiology. In this review article, we aim to summarize the complex pathophysiology and clinical diagnosis, and review the current management options.

Sickle Cell Trait Does Not Cause "Sickle Cell Crisis" Leading to Exertion-Related Death: A Systematic Review.

Globally, an estimated 300 million individuals have sickle cell trait (SCT), the carrier state for sickle cell disease. While sickle cell disease (SCD) is associated with increased morbidity and shortened lifespan, SCT has a lifespan comparable to that of the general population. However, "sickle cell crisis" has been used as a cause of death for decedents with SCT in reports of exertion-related death in athletes, military personnel, and individuals in police custody.

Increased expression of the small lysosomal gene SVIP in the Drosophila gut suppresses pathophysiological features associated with a high-fat diet.

Lysosomes are digestive organelles that are crucial for nutrient sensing and metabolism. Lysosome impairment is linked to a broad spectrum of metabolic disorders, underscoring their importance to human health. Thus, lysosomes are an attractive target for metabolic disease therapies.

Safety and efficacy of sugammadex in management of patients with myasthenia gravis undergoing general anesthesia: A systematic review.

Objective: The objective of this study was to analyze available evidence on efficacy and safety of sugammadex in reversing neuromuscular blockades in patients with Myasthenia Gravis (MG), thereby providing a comprehensive understanding of its potential benefits and risks in this specific patient population.

Methods: We performed a systematic search for studies from PubMed, Embase, Web of Science, and Google Scholar. Sources were screened using Rayyan, following predefined inclusion and exclusion criteria focusing on English articles published from 2010 to 2024 on MG patients under general anesthesia.

Effects of vitamin D and L-cysteine cosupplementation on circulating bioavailable and total 25-hydroxy-vitamin D, the free/total testosterone ratio and inflammatory biomarkers in healthy vitamin D-deficient African Americans: a placebo-controlled double-blind clinical trial.

Background: Subjects with metabolic syndrome and obesity have higher levels of inflammation with depression of the vitamin D (VD) hydroxylase/metabolising genes () required to convert VD consumed in the diet into 25(OH)VD. Compared with total 25(OH)VD levels, measurement of bioavailable 25(OH)VD is a better method to determine the beneficial effect of VD.

Objective: This study investigates whether cosupplementation with VD and L-cysteine (LC), which downregulates inflammation and upregulates VD-regulating genes, provides a better therapeutic benefit than supplementation with VD-alone in African Americans (AA).

Systemic bupropion treatment reduces long-access cocaine self-administration in male and female rats.

Background: More than 1 million people in the United States meet the criteria for cocaine use disorder (CUD), and over 19,000 people died from cocaine-related overdoses in 2020, but there are currently no FDA-approved medications for the treatment of CUD. Bupropion is an antidepressant currently prescribed to treat depression and nicotine addiction that acts by inhibiting norepinephrine and dopamine transporters.

Methods: In this study, we tested the effect of several doses of systemic bupropion on cocaine self-administration in male and female Wistar rats.

Institutional, neighborhood, and life stressors on loneliness among older adults.

Background: Loneliness is a public health epidemic in the United States (US), with older adults being vulnerable to experiencing loneliness. Predictors of loneliness are less understood among racial/ethnic groups of US older adults, and few studies have included perceived institutional discrimination (PID), stressful life events (SLE), and perceived neighborhood characteristics (PNC) as antecedent stressors of loneliness in diverse older adult samples. Our study assessed the relationship between these stressors and loneliness among specific racial/ethnic groups of older adults.

Capillary Wave-Assisted Colloidal Assembly.

Arithmetic normalisation models for the effects of lipid on carbon stable isotope values in silver carp () tissue.

Invasive silver carp () threaten Mississippi River basin ecosystems due to their ability to outcompete native species. Stable carbon (δC) and nitrogen (δN) isotope analysis has been used to study how silver carp impact native ecosystems, but lipids in fish tissues commonly bias their δC values. Chemical lipid extraction and mathematical equations that normalise δC values for lipid content can account for this bias, but have not been assessed for silver carp.

The application of non-invasive neuromodulation in stuttering: Current status and future directions.

Non-invasive neuromodulation methods such as transcranial Direct Current Stimulation (tDCS) and Transcranial Magnetic Stimulation (TMS), have been extensively utilized to enhance treatment efficacy for various neurogenic communicative disorders. Recently, these methods have gained attention for their potential to reveal more about the underlying nature of stuttering and serve as adjunct therapeutic approaches for stuttering intervention. In this review, we present existing research and discuss critical factors that might influence the efficacy of these interventions, such as location, polarity, intensity, and duration of stimulation, as well as the impact of combined behavioral training.

Dispersal of Sensu Lato Conidia from Infected Citrus and Strawberry Under Simulated Rainfall and Different Laminar and Turbulent Wind Speeds.

Species of the complex cause postbloom fruit drop of citrus and anthracnose fruit rot of strawberries. produces acervuli in diseased citrus flowers and strawberry fruit, surviving asymptomatically on vegetative tissues. Previous studies have suggested that dispersal mechanisms other than windblown rain may be involved in dispersal of conidia of sensu lato.

Climate change aggravates bird mortality in pristine tropical forests.

Stable understory microclimates within undisturbed rainforests are often considered refugia against climate change. However, this assumption contrasts with emerging evidence of Neotropical bird population declines in intact rainforests. We assessed the vulnerability of resident rainforest birds to climatic variability, focusing on dry season severity characterized by hotter temperatures and reduced rainfall.

Defect Conformal Field Theory from Sachdev-Ye-Kitaev Interactions.

The coupling between defects and extended critical degrees of freedom gives rise to the intriguing theory known as defect conformal field theory (CFT). In this work, we introduce a novel family of boundary and interface CFTs by coupling N Majorana chains with SYK_{q} interactions at the defect. Our analysis reveals that the interaction with q=2 constitutes a new marginal defect.
