Compounded glucagon-like peptide-1 receptor agonists for weight loss: the direct-to-consumer market in Colorado.

Background: High prices and other access barriers have contributed to the rise of a market for compounded glucagon-like peptide-1 receptor agonists for weight loss in the United States. This market has not been systematically studied. We conducted a pilot study to assess the prevalence, characteristics, and advertising content of direct-to-consumer providers of compounded glucagon-like peptide-1 products for weight loss in Colorado.

Prevalence of Depression in Older Adults and the Potential Protective Role of Volunteering: Findings From the LongROAD Study.

Background: As the US population continues to age, depression and other mental health issues have become a significant challenge for healthy aging. Few studies, however, have examined the prevalence of depression in community-dwelling older adults in the United States.

Methods: Baseline data from the Longitudinal Research on Aging Drivers study were analyzed to examine the prevalence and correlates of depression in a multisite sample of community-dwelling adults aged 65-79 years who were enrolled and assessed between July 2015 and March 2017.

Enterovirus and Parechovirus Neurologic Infections in Children: Clinical Presentations and Neuropathogenesis.

Enteroviruses (EVs) and parechoviruses (PeVs) are common pathogens of childhood. Enteroviral infections cause a range of clinical syndromes from mild illness to neurologic manifestations of meningitis, encephalitis, and acute flaccid myelitis. Disease manifestations are driven by a combination of viral replication and host immune response.

Long-Term Trajectories of Older Adults Served by an Emergency Department/Hospital-Based Elder Mistreatment Response Program.

Background: An emergency department (ED) visit or hospitalization provides an opportunity to identify elder mistreatment and initiate intervention, but this seldom occurs. To address this, we developed the Vulnerable Elder Protection Team (VEPT), a novel interdisciplinary consultation service. We explored the long-term trajectories of patients receiving VEPT evaluation and intervention.

The gag-like gene RTL8 antagonizes PEG10-mediated virus like particles.

PEG10 is a retroelement-derived Mart-family gene that is necessary for placentation and has been implicated in neurological disease. PEG10 resembles both retrotransposon and retroviral proteins and forms virus-like particles (VLPs) that can be purified using iodixanol ultracentrifugation. It is hypothesized that formation of VLPs is crucial to the biological roles of PEG10 in reproduction and neurological health.

Malignant Cerebral Edema After Cranioplasty: A Case Report and Literature Insights.

BACKGROUND Decompressive craniectomy is a common life-saving intervention in the setting of elevated intracranial pressure. Cranioplasty restores the calvarium and intracranial physiology once swelling recedes. Cranioplasty is often thought of as a low-risk intervention.

Structural basis for the inhibition of PRC2 by active transcription histone posttranslational modifications.

Polycomb repressive complex 2 (PRC2) trimethylates histone H3 on K27 (H3K27me3) leading to gene silencing that is essential for embryonic development and maintenance of cell identity. PRC2 is regulated by protein cofactors and their crosstalk with histone modifications. Trimethylated histone H3 on K4 (H3K4me3) and K36 (H3K36me3) localize to sites of active transcription and inhibit PRC2 activity through unknown mechanisms.

Education strategies are the most commonly used in pediatric rehabilitation implementation research: a scoping review.

Background: Approximately one in six children has a disability, and effective, evidence-based rehabilitation can ameliorate the impact of these conditions over the lifespan. However, implementing interventions in real-world settings remains a challenge. This scoping review aimed to summarize the characteristics, implementation strategies, and outcomes of implementation studies in pediatric rehabilitation.

Divergent response to radio-immunotherapy is defined by intrinsic features of the tumor microenvironment.

Background: Treatment with immunotherapy can elicit varying responses across cancer types, and the mechanistic underpinnings that contribute to response vrsus progression remain poorly understood. However, to date there are few preclinical models that accurately represent these disparate disease scenarios.

Methods: Using combinatorial radio-immunotherapy consisting of PD-1 blockade, IL2Rβγ biased signaling, and OX40 agonism we were able to generate preclinical tumor models with conflicting responses, where head and neck squamous cell carcinoma (HNSCC) models respond and pancreatic ductal adenocarcinoma (PDAC) progresses.

The Trifecta of Industry, Academic, and Health System Partnership to Improve Mental Health Care Through Smartphone-Based Remote Patient Monitoring: Development and Usability Study.

Background: Mental health treatment is hindered by the limited number of mental health care providers and the infrequency of care. Digital mental health technology can help supplement treatment by remotely monitoring patient symptoms and predicting mental health crises in between clinical visits. However, the feasibility of digital mental health technologies has not yet been sufficiently explored.

The Circadian Response to Evening Light Spectra in Early Childhood: Preliminary Insights.

Although the sensitivity of the circadian system to the characteristics of light (e.g., biological timing, intensity, duration, spectrum) has been well studied in adults, data in early childhood remain limited.

The accuracy of a patient-specific femoral planning and delivery system for total hip arthroplasty.

Introduction: A primary objective when performing a total hip arthroplasty (THA) is to restore hip biomechanics in accordance with a chosen surgical plan. The aim of this study was to assess the accuracy of a 3D-printed patient-specific guide for delivering a planned femoral osteotomy for both a posterior and an anterior approach.

Methodology: 40 patients (20 anterior and 20 posterior) scheduled for THA received a preoperative work-up allowing for patient-specific implant sizing and positioning.

Lung Endothelial Cell Heterogeneity in Health and Pulmonary Vascular Disease.

Lung endothelial cells (ECs) are essential for maintaining organ function and homeostasis. Despite sharing some common features with ECs from organ systems, lung ECs exhibit significant heterogeneity in morphology, function, and gene expression. This heterogeneity is increasingly recognized as a key contributor to the development of pulmonary diseases like pulmonary hypertension (PH).

Single-Cell Analysis in Cerebrovascular Research: Primed for Breakthroughs and Clinical Impact.

Data generated using single-cell RNA-sequencing has the potential to transform understanding of the cerebral circulation and advance clinical care. However, the high volume of data, sometimes generated and presented without proper pathophysiological context, can be difficult to interpret and integrate into current understanding of the cerebral circulation and its disorders. Furthermore, heterogeneity in the representation of brain regions and vascular segments makes it difficult to compare results across studies.

Contributors and Solutions to High Out-of-Pocket Costs for Heart Failure Medications.

As expensive therapeutics rise to the fore of heart failure management, out-of-pocket (OOP) medication costs have become increasingly relevant to patient care. Prescription medication costs influence medical decision-making and affect adherence. Yet, individualized cost estimates are seldom available during clinical encounters when prescription decisions are made.

Oral Delivery of miR146a Conjugated to Cerium Oxide Nanoparticles Improves an Established T Cell-Mediated Experimental Colitis in Mice.

Dysregulated inflammation and oxidative stress are strongly implicated in the pathogenesis of inflammatory bowel disease. We have developed a novel therapeutic that targets inflammation and oxidative stress. It is comprised of microRNA-146a (miR146a)-loaded cerium oxide nanoparticles (CNPs) (CNP-miR146a).

Non-Genotoxic and Environmentally Relevant Lower Molecular Weight Polycyclic Aromatic Hydrocarbons Significantly Increase Tumorigenicity of Benzo[]pyrene in a Lung Two-Stage Mouse Model.

The World Health Organization has classified air pollution as a carcinogen, and polycyclic aromatic hydrocarbons (PAHs) are major components of air particulates of carcinogenic concern. Thus far, most studies focused on genotoxic high molecular weight PAHs; however, recent studies indicate potential carcinogenicity of the non-genotoxic lower molecular weight PAHs (LMW PAHs) that are found in indoor and outdoor air pollution as well as secondhand cigarette smoke. We hypothesize that LMW PAHs contribute to the promotion stage of cancer when combined with benzo[]pyrene (B[]P), a legacy PAH.

Pharmacokinetics of Oral Cannabinoid Δ8-Tetrahydrocannabivarin and Its Main Metabolites in Healthy Participants.

Background: Tetrahydrocannabivarin (THCV) is a phytocannabinoid commonly found in cannabis with potential pharmacological properties; however, its post-acute pharmacokinetics (PK) in humans have not been studied yet. THCV has two isomers, Δ9- and Δ8-THCV, which seem to have different pharmacological properties. We investigated the PK of the Δ8-THCV isomer after oral administration as part of a two-phase, dose-ranging, placebo-controlled trial in healthy participants.

Enhancement of Human Immunodeficiency Virus-Specific CD8 T Cell Responses with TIGIT Blockade Involves Trogocytosis.

Natural killer (NK) and CD8 T cell function is compromised in human immunodeficiency virus type 1 (HIV-1) infection by increased expression of inhibitory receptors such as TIGIT (T cell immunoreceptor with Ig and ITIM domains). Blocking inhibitory receptors or their ligands with monoclonal antibodies (mAb) has potential to improve antiviral immunity in general and facilitate HIV eradication strategies. We assessed the impact of TIGIT engagement and blockade on cytotoxicity, degranulation, and interferon-gamma (IFN-γ) production by CD8 T cells from persons living with HIV (PLWH).

DEAD/H Box 5 (DDX5) Augments E2F1-Induced Cell Death Independent of the Tumor Suppressor p53.

In almost all cancers, the p53 pathway is disabled and cancer cells survive. Hence, it is crucially important to induce cell death independent of p53 in the treatment of cancers. The transcription factor E2F1 is controlled by binding of the tumor suppressor pRB, and induces apoptosis by activating the gene, an upstream activator of p53, when deregulated from pRB by loss of pRB function.
