Electronic band evolution between Lieb and kagome nanoribbons.

We investigate the electronic properties of nanoribbons made out of monolayer Lieb, transition, and kagome lattices using the tight-binding model with a generic Hamiltonian. It allows us to map the evolutionary stages of the interconvertibility process between Lieb and kagome nanoribbons by means of only one control parameter. Results for the energy spectra, the density of states, and spatial probability density distributions are discussed for nanoribbons with three types of edges: straight, bearded, and asymmetric.

The pediatric Brain Injury Guidelines: a retrospective clinical validation study.

Objective: Pediatric traumatic brain injury (TBI) represents a significant public health concern and source of resource utilization. The aim of this study was to establish the ability of the previously published pediatric Brain Injury Guidelines (pBIG) to identify patients with traumatic intracranial hemorrhage (ICH) who might not require routine repeat neuroimaging, neurosurgical consultation, or hospital admission in a large level I and level II trauma cohort.

Methods: Pediatric patients who presented with traumatic ICH between 2018 and 2022 at the included institutions were retrospectively reviewed and sorted into pBIG categories using clinical and radiographic criteria.

Impact of Social Determinants of Health on Primary Adherence of Oral Anticoagulants Among Patients with Newly Diagnosed Atrial Fibrillation.

Introduction: Oral anticoagulants (OAC) reduce the risk of stroke among patients with atrial fibrillation (AF). However, adherence remains suboptimal. We focused on primary nonadherence to OAC and its associations with patient characteristics-specifically social determinants of health collected in electronic health records (EHR).

Patient Characteristics, Diagnoses, and Management in a Combined Uveitis-Rheumatology Clinic.

Introduction: Combined uveitis-rheumatology clinics (combined clinics) are a relatively recent clinical care model. Here we report the demographics, ocular and systemic disease characteristics, and medications utilized in patients seen in a combined clinic at a tertiary care hospital in the USA.

Methods: Medical records were reviewed of patients seen at the Combined Clinic at the University of Colorado Hospital between January 1, 2016 and November 1, 2023.

Basic Science and Pathogenesis.

Motor proteins play a key role in neuronal functions and morphology that are important for learning and memory. We have previously reported that increased expression KIF11/Kinesin-5 overrides Aß-mediated effects on dendritic spine density and long-term potentiation in a mouse model of Alzheimer's disease (AD), effectively maintaining cognitive function in the face of Aß pathology. Here, we evaluated the association of key AD phenotypes with mRNA expression levels of a select set of Dynein motor proteins METHOD: We utilized measurements of gene expression, AD neuropathology burden, and cognition provided by the ROS/MAP study to determine whether an association exists between AD phenotypes and expression of genes for cytoplasmic and axonemal dynein heavy chains.

Basic Science and Pathogenesis.

Background: Adults with Down syndrome (DS) develop Alzheimer's disease (AD) brain pathology by their 40s due to triplication of the amyloid precursor protein (APP) gene on chromosome 21, and most develop clinical symptoms by age 50-60. Inheritance of the apolipoprotein E (apoE) ε4 allele (APOE4) is the strongest risk factor for AD besides age, whereas the ε3 allele (APOE3) does not change AD risk. The APOE4 genotype is associated with earlier and more rapid cognitive decline in both typical AD and DS-associated AD (DS-AD); however, understanding of the associated mechanisms is lacking.

Basic Science and Pathogenesis.

Background: Down Syndrome (DS) is a genetic disorder caused by the triplication of human chromosome 21 that affects approximately 1 in 700 people born in the U.S. People with DS are at a greater risk of developing Alzheimer's disease (AD), with practically all individuals developing AD histopathology and more than half progressing to dementia.

Youth Homelessness in Denver, Colorado: 2017-2021.

Objectives: Homelessness is a public health crisis in the United States, yet homelessness prevalence, especially among children and youth, is not well understood. In this study, we use an indirect estimation method known as multiple systems estimation to further evaluate prevalence of youth experiencing homelessness in Denver, Colorado.

Methods: We performed a multiple systems estimation ("capture-recapture") analysis to estimate annual homelessness among youth aged 14 to 17 years in the city and county of Denver, Colorado from 2017 to 2021.

Unsupervised machine learning analysis to identify patterns of ICU medication use for fluid overload prediction.

Background: Fluid overload (FO) in the intensive care unit (ICU) is common, serious, and may be preventable. Intravenous medications (including administered volume) are a primary cause for FO but are challenging to evaluate as a FO predictor given the high frequency and time-dependency of their use and other factors affecting FO. We sought to employ unsupervised machine learning methods to uncover medication administration patterns correlating with FO.

Venom composition, toxicity and cross-neutralization by PoliVal-ICP antivenom, of Mesoamerican jumping pitvipers genus Metlapilcoatlus (Viperidae: Crotalinae).

Background: The genus Metlapilcoatlus was recently erected to include six species of stout venomous snakes, known as the jumping pitvipers, which inhabit mountainous areas of Mesoamerica. This group maintains affinity with Atropoides picadoi, another jumping pitviper with restricted distribution in Costa Rica and Panama. Although the venom of A.

Evaluation of Peer Review of Percutaneous Coronary Intervention Operator Performance.

Background: Case-based peer review of percutaneous coronary intervention (PCI) is used by many hospitals for quality improvement and to make decisions regarding physician competency. However, there are no studies testing the reliability or validity of peer review for PCI performance evaluation.

Methods: We recruited interventional cardiologists from 12 Veterans Affairs Health System facilities throughout the United States to provide PCI cases for review.

Feasibility of at-Home Sleep Monitoring in Adolescents with and without Concussion.

Background: Poor sleep is associated with longer recovery following adolescent concussion, making the longitudinal assessment of sleep important for monitoring recovery and identifying sleep disruptions. An important consideration for successful monitoring of sleep following concussion is the feasibility and adherence of a given sleep monitoring tool when used in an at-home environment. Understanding the usability of different sleep monitoring tools is essential for determining their applicability for longitudinal assessment in an ecologically valid environment.

Precision Medicine for Pulmonary Vascular Disease: The Future Is Now (2023 Grover Conference Series).

Pulmonary vascular disease is not a single condition; rather it can accompany a variety of pathologies that impact the pulmonary vasculature. Applying precision medicine strategies to better phenotype, diagnose, monitor, and treat pulmonary vascular disease is increasingly possible with the growing accessibility of powerful clinical and research tools. Nevertheless, challenges exist in implementing these tools to optimal effect.

Pseudo-endocrine Disorders: Recognition, Management, and Action.

"Pseudo-endocrine disorders" refer to proposed conditions that have never been scientifically proven to exist but, due to widespread misinformation available on the internet and other media, are relatively commonly diagnosed and treated with equally unproven and sometimes dangerous treatments. Adrenal fatigue is a nonexistent condition that supposedly results from adrenal exhaustion and atrophy due to chronic stress and has been promoted as a potential explanation for a variety of symptoms. Testing consists of nonvalidated online surveys and salivary cortisol profiles while treatment is not evidence-based at best and can be dangerous.

Education Research: The Neurohumanities in Training: Integrating a Humanities Curriculum Within Neurology Residency Programs.

Background And Objectives: Perhaps stemming from the central role of detailed examinations and a focus on the subjective sphere that grounds their clinical practice, neurologists have frequently opined on experiences traditionally a province of humanities. The increasingly technological focus on medical education and care can be seen to devalue the subjective aspects of medicine. As a counter to this, we report on the existence of neurohumanities curricula within neurology residency training.

Artificial Intelligence Assistance in Point-of-Care Ultrasound Skill Retention for Novice Users in Space Medicine Scenarios.

Introduction: As humanity progresses further into space, astronauts must be increasingly independent from mission control, especially in high-consequence medical scenarios. The high-utility and low-mass nature of point-of-care ultrasound (POCUS) makes this imaging modality ideal for spaceflight mission deployment. However, POCUS operator skill degrades over time, presenting an operational barrier to continuous, effective use.

Food Allergy Prevalence in Two Population-Based UK Cohorts Born 12 Years Apart.

Background: Adverse food reactions include food allergy (FA; immune-mediated) and food intolerances (non-immune-mediated). FA are classified into IgE- and non-IgE-mediated FA. There is limited information available about changes in FA prevalence over time.

Criminal legal penalties, substance use, and overdose: a concept mapping study examining Colorado's criminal legal penalties.

Background: In the USA, many states, including Colorado, have increased criminal penalties for illicit opioid possession, which may alter overdose risk. We aimed to evaluate the relationship between Colorado's increased drug-related criminal legal penalties, risk of overdose, and substance use patterns.

Methods: We used concept mapping - a mixed-methods approach used to develop a conceptual understanding of an issue from a community lens - to engage with people with living and/or lived experience with the criminal legal system, substance use, and/or overdose, their loved ones, and service providers.

Frequency of Spondyloarthritis Symptoms Among U.S. Patients with Inflammatory Bowel Disease: A Cross-sectional Multi-Center Study.

Objective: Spondyloarthritis (SpA) is the most common extraintestinal manifestation of inflammatory bowel disease (IBD). The application of screening tools to detect SpA in patients with IBD may lead to earlier recognition of SpA and affect treatment decisions.

Methods: A combination of two previously described SpA screening questionnaires, DETAIL and IBIS-Q, was administered to consecutive patients with IBD attending IBD specialty clinics in six U.

Identification of ferroptosis-related signature predicting prognosis and therapeutic responses in pancreatic cancer.

Ferroptosis plays a role in tumorigenesis by affecting lipid peroxidation and metabolic pathways; however, its prognostic or therapeutic relevance in pancreatic adenocarcinoma (PAAD) remains poorly understood. In this study, we developed a prognostic ferroptosis-related gene (FRG)-based risk model using cohorts of The Cancer Genome Atlas (TCGA) and the International Cancer Genome Consortium (ICGC), proposing plausible therapeutics. Differentially expressed FRGs between tumors from TCGA-PAAD and normal pancreatic tissues from Genotype-Tissue Expression were analyzed to construct a prognostic risk model using univariate and multivariate Cox regression and LASSO analyses.

A stromal inflammasome Ras safeguard against Myc-driven lymphomagenesis.

The inflammasome plays multifaceted roles in cancer, but less is known about its function during premalignancy upon initial cell transformation. We report a homeostatic function of the inflammasome in suppressing malignant transformation through Ras inhibition. We identified increased hematopoietic stem cell (HSC) proliferation within the bone marrow of inflammasome-deficient mice.

Antigen experience history directs distinct functional states of CD8 CAR T cells during the antileukemia response.

Although chimeric antigen receptor (CAR) T cells are effective against B-lineage malignancies, post-CAR relapse is common, and efficacy in other tumors is limited. These challenges may be addressed through rational manipulations to control CAR T cell function. Here we examine the impact of cognate T cell antigen experience on subsequent CD8 CAR T cell activity.
