Implementing an AI algorithm in the clinical setting: a case study for the accuracy paradox.

Objectives: We report our experience implementing an algorithm for the detection of large vessel occlusion (LVO) for suspected stroke in the emergency setting, including its performance, and offer an explanation as to why it was poorly received by radiologists.

Materials And Methods: An algorithm was deployed in the emergency room at a single tertiary care hospital for the detection of LVO on CT angiography (CTA) between September 1st-27th, 2021. A retrospective analysis of the algorithm's accuracy was performed.

Extracellular Vesicles in Implantation: Cross-Talk Between the Embryo and Endometrium.

Extracellular vesicles (EVs), including exosomes and microvesicles, have emerged as pivotal mediators of intercellular communication. Embryo implantation is a critical process in early pregnancy and requires communication between the embryo and maternal uterus. EVs are important in coordinating the communication between the embryo and maternal uterus.

Cystic masses of the pediatric lung: update on congenital pulmonary airway malformation and its differential diagnosis.

Localized cystic lung lesions in pediatric patients encompass a spectrum of benign and rare malignant conditions that are quite distinct from cystic lung disease arising in adulthood. The majority have historically fallen under the diagnostic category of "congenital pulmonary airway malformation," a term that has been used to denote a diverse group of diseases ranging in etiology from ectopia to bronchial atresia to mosaic oncogenic mutation or neoplasia. This article reviews the clinical characteristics, gross and histologic features, and pathogenetic underpinnings of congenital pulmonary airway malformation as well as lesions that enter its histologic differential diagnosis.

EGFR status assessment using reflex testing targeted next-generation sequencing for resected non-squamous non-small cell lung cancer.

EGFR status assessment is mandatory for adjuvant decision-making of resected stage IB-IIIA non-squamous non-small cell lung cancer (NS-NSCLC). It is questionable whether single-gene RT-PCR versus next-generation sequencing (NGS) should be used for this evaluation. Moreover, co-occurring mutations have an impact on tumor behavior and may influence future therapeutic decision-making.

A Needs Assessment of Labor and Delivery Nurses Performing NRP in the Delivery Room.

Introduction: Labor and delivery (L&D) nurses are often responsible for initiating the critical first steps of the Neonatal Resuscitation Program (NRP). Identification of knowledge gaps and underlying reasons for NRP non-adherence is crucial for designing educational interventions.

Methods: A convenience sample of 37 L&D nurses from two delivery hospitals were enrolled.

The impact of gender-affirming interventions on eating disorder diagnosis risk among transgender and gender-diverse individuals.

Background: The objective of this study is to evaluate the risk of being diagnosed with an eating disorder among transgender and gender-diverse (TGD) individuals, specifically examining how this risk differs following gender-affirming medical therapy (GAMT).

Methods: The study utilizes electronic medical record (EMR) data from the TriNetX database. A total of 90,955 TGD individuals were identified in the TriNetX database.

Modeling bladder mechanics with 4D reconstruction of murine ex vivo bladder filling.

This study presents a novel methodology for high-resolution 3D bladder modeling during filling, developed by leveraging improved imaging and computational techniques. Using murine bladder filling data, the methodology generates accurate 3D geometries across time, enabling in-depth mechanical analysis. Comparison with a traditional spherical model revealed similar stress trends, but the 3D model permitted nuanced quantifications, such as localized surface curvature and stress analysis.

Cigarette smoking is associated with reduced neuroinflammation and better cognitive control in people living with HIV.

People living with HIV (HIV+) are roughly twice as likely to smoke cigarettes (Smok+) as the general population. With the advent of effective antiretroviral therapies, it is increasingly important to understand the effects of chronic HIV infection and cigarette smoking on brain function and cognition since HIV+ individuals have heightened neuroinflammation and cognitive deficits even with such therapies. Based on prior studies demonstrating that smoking reduces a marker for neuroinflammation in HIV- individuals, we hypothesized that HIV+/Smok+ individuals would have less neuroinflammation and better cognitive control than HIV+/Smok- individuals.

Simulation training with haptic feedback of instrument vibrations reduces resident workload during live robot-assisted sleeve gastrectomy.

Background: New surgeons experience heavy workload during robot-assisted surgery partially because they must use vision to compensate for the lack of haptic feedback. We hypothesize that providing realistic haptic feedback during dry-lab simulation training may accelerate learning and reduce workload during subsequent surgery on patients.

Methods: We conducted a single-blinded study with 12 general surgery residents (third and seventh post-graduate year, PGY) randomized into haptic and control groups.

Longitudinal changes in reinforcement learning during smoking cessation: a computational analysis using a probabilistic reward task.

Despite progress in smoking reduction in the past several decades, cigarette smoking remains a significant public health concern world-wide, with many smokers attempting but ultimately failing to maintain abstinence. However, little is known about how decision-making evolves in quitting smokers. Based on preregistered hypotheses and analysis plan ( https://osf.

SPOCK2 controls the proliferation and function of immature pancreatic β-cells through MMP2.

Human pluripotent stem cell-derived β-cells (SC-β-cells) represent an alternative cell source for transplantation in diabetic patients. Although mitogens could in theory be used to expand β-cells, adult β-cells very rarely replicate. In contrast, newly formed β-cells, including SC-β-cells, display higher proliferative capacity and distinct transcriptional and functional profiles.

Trogocytosis-mediated immune evasion in the tumor microenvironment.

Trogocytosis is a dynamic cellular process characterized by the exchange of the plasma membrane and associated cytosol during cell-to-cell interactions. Unlike phagocytosis, this transfer maintains the surface localization of transferred membrane molecules. For example, CD4 T cells engaging with antigen-presenting cells undergo trogocytosis, which facilitates the transfer of antigen-loaded major histocompatibility complex (MHC) class II molecules from antigen-presenting cells to CD4 T cells.

Unraveling the associations between voice pitch and major depressive disorder: a multisite genetic study.

Major depressive disorder (MDD) often goes undiagnosed due to the absence of clear biomarkers. We sought to identify voice biomarkers for MDD and separate biomarkers indicative of MDD predisposition from biomarkers reflecting current depressive symptoms. Using a two-stage meta-analytic design to remove confounds, we tested the association between features representing vocal pitch and MDD in a multisite case-control cohort study of Chinese women with recurrent depression.

Proteolysis targeting chimera (PROTAC)-driven antibody internalization of oncogenic cell surface receptors.

Antibody-drug conjugates (ADCs) are increasingly used in clinic for multiple indications and may improve upon the activity of parental antibodies by delivering cytotoxic payloads into target cells. This activity is predicated upon internalization to release the cytotoxic payloads intracellularly. Since binding of ADCs to their cell surface targets does not guarantee their internalization, we hypothesize that proteolysis targeting chimeras (PROTACs) could improve the activity of ADCs through forced internalization.

Energetics of substrate transport in proton-dependent oligopeptide transporters.

The PepT transporter mediates the transport of peptides across biological membranes. Despite advancements in structural biology, including cryogenic electron microscopy structures resolving PepT in different states, the molecular basis of peptide recognition and transport by PepT is not fully elucidated. In this study, we used molecular dynamics simulations, Markov State Models (MSMs), and Transition Path Theory (TPT) to investigate the transport mechanism of an alanine-alanine peptide (Ala-Ala) through the PepT transporter.

An isothermal calorimetry assay for determining steady state kinetic and Ensitrelvir inhibition parameters for SARS-CoV-2 3CL-protease.

This manuscript details the application of Isothermal Titration Calorimetry (ITC) to characterize the kinetics of 3CL, the main protease from the Severe Acute Respiratory Syndrome CoronaVirus-2 (SARS-CoV-2), and its inhibition by Ensitrelvir, a known non-covalent inhibitor. 3CL is essential for producing the proteins necessary for viral infection, which led to the COVID-19 pandemic. The ITC-based assay provided rapid and reliable measurements of 3CL activity, allowing for the direct derivation of the kinetic enzymatic constants K and k by monitoring the thermal power required to maintain a constant temperature as the substrate is consumed.

Open problems in synthetic multicellularity.

Multicellularity is one of the major evolutionary transitions, and its rise provided the ingredients for the emergence of a biosphere inhabited by complex organisms. Over the last decades, the potential for bioengineering multicellular systems has been instrumental in interrogating nature and exploring novel paths to regeneration, disease, cognition, and behaviour. Here, we provide a list of open problems that encapsulate many of the ongoing and future challenges in the field and suggest conceptual approaches that may facilitate progress.

Membrane-targeted push-pull azobenzenes for the optical modulation of membrane potential.

We introduce a family of membrane-targeted azobenzenes (MTs) with a push-pull character as a new tool for cell stimulation. These molecules are water soluble and spontaneously partition in the cell membrane. Upon light irradiation, they isomerize from trans to cis, changing the local charge distribution and thus stimulating the cell response.

Sub-terahertz transmissive reconfigurable intelligent surface for integrated beam steering and self-OOK-modulation.

Boasting superior flexibility in beam manipulation and a simpler framework than traditional phased arrays, terahertz metasurface-based phased arrays show great promise for 5G-A/6G communication networks. Compared with the reflective reconfigurable intelligent surface (reflective RIS), the transmissive RIS (TRIS) offers more feasibility for transceiver multiplexing systems to meet the growing demand for high-performance beam tracking in terahertz communication and radar systems. However, the terahertz TRIS encounters greater challenges in phase shift, beam efficiency, and complex circuitry.

Enhanced sensitivity via non-Hermitian topology.

Sensors are indispensable tools of modern life that are ubiquitously used in diverse settings ranging from smartphones and autonomous vehicles to the healthcare industry and space technology. By interfacing multiple sensors that collectively interact with the signal to be measured, one can go beyond the signal-to-noise ratios (SNR) attainable by the individual constituting elements. Such techniques have also been implemented in the quantum regime, where a linear increase in the SNR has been achieved via using entangled states.

"When you leave out the door": The streets, Medicaid, and boundary spaces of healthcare in urban poverty.

Attending closely to the lived experiences of people moving in and out of Medicaid-funded institutions, I argue that "the streets" are critical to understanding healthcare in US urban poverty. Exploring the relationship between "the streets" and Medicaid-funded institutions, this essay asks: How does the relationship between "the streets"-and in the words of my research interlocutors-"life on the other side" shape life in Medicaid-funded institutions in the Northeast US city? How do the social and symbolic conditions of this relationship-conditions structured by anti-Blackness-formulate the human in urban poverty? By joining Medicaid-funded institutions together as a broader health-governing network, I demonstrate how these institutions become boundary spaces that reveal the socially and symbolically interdependent worlds of "the streets" and life off them. Ultimately, this essay argues that "the streets" contain the social and symbolic conditions that dehumanize the poor through the logics of anti-Blackness, thus defining the terms of humanization that Medicaid-funded institutions afford.

Anesthesia and Myopathies of Horses.

Pre-existing muscle disorders in horses can often be subtle and may only become evident during or after anesthesia. Advancements in veterinary medicine, along with increased knowledge and research in this field, help minimize anesthesia-related problems. Adequate preanesthesia assessment, early disease diagnosis, and proper management are crucial in minimizing risks to the neuromuscular system during general anesthesia.
