Light-dark shift promotes colon carcinogenesis through accelerated colon aging.

Colorectal cancer (CRC) is the third most common cancer worldwide, with rising prevalence among younger adults. Several lifestyle factors, particularly disruptions in circadian rhythms by light-dark (LD) shifts, are known to increase CRC risk. Epidemiological studies previously showed LD-shifts are associated with increased risk of CRC.

Adaptive measurement of cognitive function based on multidimensional item response theory.

Introduction: Up to 20% of older adults in the United States have mild cognitive impairment (MCI), and about one-third of people with MCI are predicted to transition to Alzheimer's disease (AD) within 5 years. Standard cognitive assessments are long and require a trained technician to administer. We developed the first computerized adaptive test (CAT) based on multidimensional item response theory (MIRT) to more precisely, rapidly, and repeatedly assesses cognitive abilities across the adult lifespan.

at Scientific Sessions 2023: Moving Toward Social Justice in Cardiovascular Health in the United States.

Attention to social justice is essential to improving cardiovascular health outcomes. In the absence of social justice, equitable cardiovascular health is impossible. This viewpoint provides a brief synopsis of the 2023 -sponsored session titled "Moving Towards Social Justice in Cardiovascular Health.

Prospective associations of interleukin-6 and allele with cognitive decline in biracial community-dwelling older adults: The Chicago Health and Aging Project (CHAP).

Introduction: It is unclear whether inflammation, that is, high interleukin-6 (IL-6) levels, and genetic risk, that is, apolipoprotein E () ε4 allele, have a compounding effect on cognitive decline (CD).

Methods: We analyzed a subset of participants from the longitudinal cohort study, Chicago Health and Aging Project, comprising 1120 biracial community-dwelling older adults (60% Black and 62% women), and mean follow-up = 6.4 years.

Failure to Rescue After Resection of Perhilar Cholangiocarcinoma in an International Multicenter Cohort.

Background: Failure to rescue (FTR) is defined as the inability to prevent death after the development of a complication. FTR is a parameter in evaluating multidisciplinary postoperative complication management. The aim of this study was to evaluate FTR rates after major liver resection for perihilar cholangiocarcinoma (pCCA) and analyze factors associated with FTR.

Landscape of exosomes to modified exosomes: a state of the art in cancer therapy.

Exosomes are a subpopulation of extracellular vesicles (EVs) that naturally originate from endosomes. They play a significant role in cellular communication. Tumor-secreted exosomes play a crucial role in cancer development and significantly contribute to tumorigenesis, angiogenesis, and metastasis by intracellular communication.

Educator's blueprint: Key considerations for using social media in survey-based medical education research.

In this paper, we present a set of recommendations for using social media as a tool for participant recruitment in survey-based medical education research. Drawing from a limited but growing body of literature, we discuss the opportunities and challenges inherent to social media recruitment. This article builds on the authors' previous educator's blueprints about survey design and administration.

Educator's blueprint: A how-to guide for creating high-quality slides.

Didactics are the primary modality in which educators disseminate knowledge. The accompanying slides are a critical element, which can enhance or distract from the corresponding presentation. This Educator's Blueprint provides 10 strategies for creating high-quality presentation slides.

Trends and predictors of unfilled emergency medicine residency positions: A comparative analysis of the 2023 and 2024 Match cycles.

Background: The emergency medicine (EM) landscape has evolved due to the increasing number of programs paired with fewer applicants. This study analyzed the characteristics of EM residency programs associated with unfilled positions during the 2024 Match and compared them with data from the 2023 Match to identify persistent and emerging trends influencing these outcomes.

Methods: In this cross-sectional, observational study, we investigated factors associated with unfilled EM residency positions in the 2024 Match.

Biological effects of sodium phenylbutyrate and taurursodiol in Alzheimer's disease.

Introduction: Sodium phenylbutyrate and taurursodiol (PB and TURSO) is hypothesized to mitigate endoplasmic reticulum stress and mitochondrial dysfunction, two of many mechanisms implicated in Alzheimer's disease (AD) pathophysiology.

Methods: The first-in-indication phase 2a PEGASUS trial was designed to gain insight into PB and TURSO effects on mechanistic targets of engagement and disease biology in AD. The primary clinical efficacy outcome was a global statistical test combining three endpoints relevant to disease trajectory (cognition [Mild/Moderate Alzheimer's Disease Composite Score], function [Functional Activities Questionnaire], and total hippocampal volume on magnetic resonance imaging).

Cardiovascular Diseases Increase Cancer Mortality in Adults: NHANES-Continuous Study.

Background: Both cancer and cardiovascular disease (CVD) are the leading causes of death worldwide. Although our previous study detected a relationship between CVD and cancer incidence, limited evidence is available regarding the relationship between CVD, cardiovascular risk factors, and cancer mortality.

Methods And Results: A prospective cohort study using data from the continuous NHANES (National Health and Nutrition Examination Survey, 1999-2016) merged with Medicare and National Death Index mortality data, through December 31, 2018.

Comparative Performance of ChatGPT 3.5 and GPT4 on Rhinology Standardized Board Examination Questions.

Objective: Advances in deep learning and artificial intelligence (AI) have led to the emergence of large language models (LLM) like ChatGPT from OpenAI. The study aimed to evaluate the performance of ChatGPT 3.5 and GPT4 on Otolaryngology (Rhinology) Standardized Board Examination questions in comparison to Otolaryngology residents.

Genetics and Pathophysiological Mechanisms of Lipoprotein(a)-Associated Cardiovascular Risk.

Elevated lipoprotein(a) is a genetically transmitted codominant trait that is an independent risk driver for cardiovascular disease. Lipoprotein(a) concentration is heavily influenced by genetic factors, including kringle IV-2 domain size, single-nucleotide polymorphisms, and interleukin-1 genotypes. Apolipoprotein(a) is encoded by the gene and contains 10 subtypes with a variable number of copies of kringle -2, resulting in >40 different apolipoprotein(a) isoform sizes.

Incorporating implementation science principles into curricular design.

Implementation science (IS) is an approach focused on increasing the application of evidence-based health interventions into practice, through purposive and thoughtful planning to maximize uptake, scalability, and sustainability. Many of these principles can be readily applied to medical education, to help augment traditional approaches to curriculum design. In this paper, we summarize key components of IS with an emphasis on application to the medical educator.

Immune Checkpoint Inhibitors and Cardiotoxicity: A Comparative Meta-Analysis of Observational Studies and Randomized Controlled Trials.

Background: Immune checkpoint inhibitors (ICIs) have uncommon associations with cardiotoxicity, yet these cardiotoxic effects are associated with high mortality. An accurate assessment of risk for cardiotoxicity is essential for clinical decision-making, but data from randomized controlled trials often differ from real-world observational studies.

Methods And Results: A systematic search of PubMed, Embase, Cochrane Library, and Scopus was performed, including phase II and III randomized controlled trials (RCTs) and observational studies (OSs) reporting myocarditis or pericardial disease, myocardial infarction, or stroke with an immunotherapy.
