Rectal squamous metaplasia in inflammatory bowel disease is rare. We present 2 cases of rectal squamous metaplasia, one in a patient with Crohn's disease and another with ulcerative colitis. Given the risk of malignant transformation, dysplasia surveillance is important particularly in areas of chronic inflammation.

Background: Metastatic colon cancer (MCC) is a debilitating condition with a poor prognosis. Currently, there is limited data that investigates MCC in relation to mismatch repair (MMR) status. The aims of this study are to compare sociodemographic and clinicopathologic features and mortality between patients with MMR-proficient (MMR-P) and MMR-deficient (MMR-D) MCC.

Cardiac disease in young children can be unrecognized until symptoms are unmasked by a precipitating event, such as an infection. We present a case of anomalous left coronary artery from the pulmonary artery causing clinically significant disease in a four-month-old male with concomitant mitral regurgitation and pulmonary coccidioidomycosis who required modification of his surgical management due to the infection. This case highlights how timely diagnosis and perioperative management and recovery can be affected by concurrent infections in patients with congenital heart disease.

Background: With increasingly restricted access to facility-based abortion in the United States, pregnant people are increasingly relying on models of care that utilize history-based or no-test approaches to eligibility assessment. Minimal research has examined the accuracy of abortion patients' self-assessment of eligibility for medication abortion using their health history, a necessary step towards ensuring optimal access to history-based or no-test models, as well as potential over-the-counter access.

Objective: To examine the accuracy of pregnant people's eligibility for medication abortion determined using their self-reported health history as compared to clinician assessment with ultrasound and other tests.

Carcinogenetic mechanisms employed by the oral microbiome: a narrative review.

Am J Med Sci

January 2025

Cancers of the oral cavity, lip, salivary gland, and oropharynx cause substantial global disease burden. While tobacco-use and alcohol use are highly associated with oral cancers, the rising incidence of disease in patients who do not use tobacco or alcohol points to additional carcinogenic risk factors. Chronic inflammation, disruption of the oral microbiome, and dysbiosis are becoming more widely implicated in the pathogenesis of oral cancer.

BRAF and MEK inhibitor (BRAFi + MEKi) therapy has improved the treatment of solid tumors with BRAF mutation. However, their neurologic adverse events (nAEs) have been largely unexplored. This study aimed to provide clinicians with more updated knowledge on nAEs associated with BRAFi + MEKi therapy in patients with malignant melanoma compared with nonmelanoma cancers.

Cholangiocarcinoma is a heterogenous malignancy with various classifications based on location, morphological features, histological features, and actionable genetic mutations. Intrahepatic cholangiocarcinoma (ICC), which arises in and proximal to second order bile ducts, is the second most common primary liver malignancy after hepatocellular carcinoma. In this review, we will discuss ICC risk factors, precursor lesions, various growth, anatomic, morphologic, and histologic classifications, rare variants, and differential diagnoses.

Several microRNAs (miRNAs) strongly influence blood pressure and the development of hypertension by modulating vascular, renal, and other physiological mechanisms. In addition, miRNAs may contribute to the genetic regulation of blood pressure. Future research should focus on investigating select miRNAs with potent physiological effects, understanding cellular context-dependent mechanisms conferring specificity to miRNA action, and integrating miRNAs as powerful modulators into the molecular system that underlies the regulation of blood pressure and the development of hypertension.

Background The use of automatic external defibrillators (AEDs) by lay rescuers can reduce the time to defibrillation and improve survival in out-of-hospital cardiac arrest (OHCA). AEDs use voice prompts to guide users through the defibrillation process, creating a potential barrier for deaf and hard-of-hearing (HoH) individuals. The objective of this study is to assess familiarity with and concerns regarding AED use among members of these communities.

Aim: Chemoradiation therapy (CRT) is considered as the first line of treatment for patients with squamous cell carcinoma of the anal canal. Following initial CRT, patients who present with either persistent or locally recurrent disease are treated by surgical intervention. The aim of our study is to determine the prognostic factors associated with failure of CRT and overall mortality in patients with anal squamous cell carcinoma (SCC).

Volumetric CT Assessment of In Situ Induced Hepatic Lesions in a Transgenic Swine Model.

Life (Basel)

October 2024

Department of Interventional Radiology, MD Anderson Cancer Center, The University of Texas, 1515 Holcombe Blvd., Houston, TX 77030, USA.

The growth rate of in situ-induced hepatic lesions in an Oncopig large animal model is quantitatively assessed. Oncopigs (n = 9) received baseline triple-phase CT scans prior to lesion induction. Lesions were subsequently induced by delivering the Ad-Cre vector to four locations in the liver.

Article Synopsis
  • - The study aimed to explore how a polygenic risk score (PRS) for QT prolongation (QTc-PRS) is linked to QTc intervals and sudden cardiac death (SCD) in people with and without sleep-disordered breathing (SDB) using data from the UK Biobank.
  • - Results showed that a higher QTc-PRS was connected to longer QTc intervals, with SDB significantly affecting the relationship between QTc-PRS and SCD risk; those with SDB had a much higher risk of SCD.
  • - In particular, Black participants with SDB were found to have a notably high risk of sudden cardiac death, highlighting the importance of SDB as a modifier for genetic risk factors.

Introduction: For the first time, our study tracked disparities in the utilization of audio-video and audio-only telehealth for outpatient visits before and during the COVID-19 pandemic.

Methods: Using a dataset of de-identified claims corresponding to telehealth and in-person visits, a retrospective cohort study was conducted for all beneficiaries continuously enrolled in Arizona Medicaid between October 2019 and November 2020. Our definition of telehealth only covered outpatient services delivered remotely via the audio-video or audio-only modality.

The physiologic sequelae of the atypical vasculature in patients with congenital heart disease can result in potentially fatal lymphatic complications, especially after corrective cardiac surgery. Transcatheter embolization of the thoracic duct or lymphatic collaterals can reduce morbidity and mortality in these patients. While typically performed transabdominally via an antegrade approach, retrograde embolization may be preferable in cases where this is not feasible, including in rare variants of thoracic duct anatomy.
