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.

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.

Background: There is an ongoing debate on surgical training and its evolution to meet the demands of a complex and changing healthcare environment.

Methods: A GI Surgery Summit was held in January 2024 that included prominent leaders and rising talents from the Society for Surgery of the Alimentary Tract, Society of Surgical Oncology, Association for Academic Surgery, and Society of University Surgeons. This meeting was held to address the multifaceted current and future challenges of surgery.

Background: Coronary microvascular dysfunction (CMD) is a common cause of angina with no obstructive coronary artery disease (ANOCA), and effective treatment options are limited.

Objectives: This study aims to assess the safety and efficacy of the coronary sinus (CS) Reducer (Neovasc, Inc/Shockwave Medical) for treatment of angina in patients with CMD.

Methods: This Phase II trial enrolled 30 patients with ANOCA, invasively diagnosed CMD, and Canadian Cardiovascular Society (CCS) class 3 to 4 angina despite medical therapy.

Arterioles are small blood vessels located just upstream of capillaries in nearly all tissues. The constriction and dilation of arterioles regulate tissue perfusion and are primary determinants of systemic blood pressure (BP). Abnormalities in arterioles are central to the development of major diseases such as hypertension, stroke, and microvascular complications of diabetes.

Article Synopsis
  • - The study investigates peripartum cardiomyopathy (PPCM) mortality rates from 1999 to 2020 and how they relate to social vulnerability as measured by the Social Vulnerability Index (SVI), finding significant disparities based on demographics and geographical locations.
  • - Researchers analyzed mortality data and SVI rankings across U.S. counties, revealing that Black populations and residents in the Southern U.S. experienced the highest age-adjusted mortality rates (AAMRs), with higher SVI linked to increased excess deaths.
  • - The findings highlight that higher social vulnerability is associated with increased PPCM mortality, indicating that both racial background and geographic location contribute to health disparities in the U.S.

Rationale: Obstructive sleep apnea (OSA) is a common condition that is usually treated by continuous positive airway pressure (CPAP) therapy, but poor adherence is common and is associated with worse patient outcomes and experiences. Patient satisfaction is increasingly adopted as a quality indicator by healthcare systems.

Objective: We tested the hypothesis that peer-driven intervention effected through interactive voice-response(PDI-IVR) system leads to better patient satisfaction (primary outcome), care-coordination, and CPAP adherence when compared to active-control.

BACKGROUNDIn type 1 diabetes (T1D), impaired insulin sensitivity may contribute to the development of diabetic kidney disease (DKD) through alterations in kidney oxidative metabolism.METHODSYoung adults with T1D (n = 30) and healthy controls (HCs) (n = 20) underwent hyperinsulinemic-euglycemic clamp studies, MRI, 11C-acetate PET, kidney biopsies, single-cell RNA-Seq, and spatial metabolomics to assess this relationship.RESULTSParticipants with T1D had significantly higher glomerular basement membrane (GBM) thickness compared with HCs.

Key Points: Proteomics analyses identified seven proteins predictive of time to development of albuminuria among youth with type 2 diabetes in the Treatment Options for Type 2 Diabetes in Adolescents and Youth cohort, 118 proteins predictive of time to development of hyperfiltration, and three proteins predictive of time to rapid eGFR decline. Seven proteins were predictive of all three outcomes (SEM4A, PSB3, dihydroxyphenylalanine decarboxylase, C1RL1, T132A, pyruvate carboxylase, and C1-esterase inhibitor) and have been implicated in immune regulatory mechanisms, metabolic dysregulation, proteostasis, and cellular signaling pathways. Elastic net Cox proportional hazards model identified distinct multiprotein signatures (38–68 proteins) of time to albuminuria, hyperfiltration, and rapid eGFR decline with concordance for models with clinical covariates and selected proteins between 0.

Over the past decade, there has been a resurgence of interest in the thoracic duct and central lymphatic system and its disorders, stimulated by advances in interventional magnetic resonance imaging techniques and urgent challenges in the clinical management of lymphatic malformations and lymphatic complications from congenital heart disease. The following chapter reprinted here written shortly after the formal founding of the discipline of lymphology and the International Society of Lymphology, describes early efforts, and also suggests future directions now being revisited and others yet to be explored (1).
