Article Abstract

Background And Aim: Combined hepatocellular-cholangiocarcinoma (CHC) is a rare liver malignancy. In this study, we compared patient characteristics and outcomes for primary CHC, intrahepatic cholangiocarcinoma (ICC), and hepatocellular carcinoma (HCC).

Methods: Medical records of patients with tissue-proven CHC (65 cases) treated at the Chang Gung Memorial Hospital between 1991 and 2005 were retrospectively reviewed. These records were compared to records of patients diagnosed with tissue-proven HCC (1985 cases) and ICC (127 cases) during the same period.

Results: Hepatitis B and C are major causes of CHC. CHC patients exhibited greater similarity to HCC than to ICC patients with respect to cirrhotic changes, age, and positive serology for hepatitis B surface antigen and anti-hepatitis C antibody. Survival was related to tumor characteristics and intervention therapies, but not to etiologies.

Conclusions: The clinical characteristics of CHC are similar to those of HCC, but overall survival is more similar to that of ICC; survival may be related to tumor biology rather than the cause. Multimodal treatment with an initial aggressive therapeutic approach can improve survival.

Importance: Previous data suggest that the time changes associated with daylight savings time (DST) may be associated with an increased incidence of acute myocardial infarction (AMI).

Objective: To determine whether the incidence of patients presenting with AMI is greater during the weeks during or after DST and compare the in-hospital clinical events between the week before DST and after DST.

Design, Setting, And Participants: This cross-sectional study examined patients enrolled in the Chest Pain MI Registry from 2013 to 2022.

Background: Migraine care is often suboptimal owing to undertreatment, variation in clinical outcomes and administration methods among existing treatments, and between- and within-individual heterogeneity in the clinical course of migraine. In response to these challenges, preference studies have been increasingly conducted to inform treatment decision-making and development. However, gaps remain in understanding how treatment preferences have been assessed across different migraine studies.

Cardiovascular Risk Prediction in Older Adults.

Curr Atheroscler Rep

September 2025

Department of Medicine, Division of Cardiovascular Disease, University of Alabama at Birmingham, 521 19th Street South-GSB 444, Birmingham, AL, 35233, USA.

Purpose Of Review: This review examines cardiovascular disease (CVD) risk prediction models relevant to older adults, a rapidly expanding population with elevated CVD risk. It discusses model characteristics, performance metrics, and clinical implications.

Recent Findings: Some models have been developed specifically for older adults, while several others consider a broader age range, including some older individuals.

Background: IgA nephropathy is a disease with a highly variable natural history, for which there is an increasing understanding of the role of complement activation in its pathogenesis and progression. We aimed to assess the clinical and prognostic implications of C4d staining in the kidney biopsy of IgA nephropathy patients.

Methods: This was a retrospective observational study wherein the medical records of IgA nephropathy patients were reviewed and baseline characteristics, kidney biopsy findings, treatment response and follow-up data were noted.

Purpose: Breast cancer (BC) is the most frequent cancer among women and the second leading cause of central nervous system (CNS) metastases. While the epidemiology of CNS metastases from BC has been well described, little is known about the treatment patterns and outcomes of young women < 40 years of age with BC that is metastatic to the CNS.

Methods: In this retrospective analysis, we identified patients with metastatic breast cancer (MBC) to the CNS who were treated at the Sunnybrook Odette Cancer Center, Toronto, Canada between 2008 and 2018.
