Pancreatoscopy plays a significant role in the diagnosis and treatment of pancreatic diseases. However, the risk of pancreatoscopy is remarkably greater than that of other endoscopic procedures, such as gastroscopy and bronchoscopy, owing to its severe invasiveness. In comparison, virtual pancreatoscopy (VP) has shown notable advantages.

Article Synopsis
  • Despite an increase in aortic valve replacement (AVR) procedures for aortic stenosis (AS), a significant number of patients who need the treatment remain untreated, especially those in low gradient subgroups.
  • The study analyzed data from 10,795 patients over 18 years to determine trends in AVR utilization based on various clinical indications and AS classifications.
  • While the overall number of AVR procedures increased, the proportion of patients who received AVR, particularly in low gradient categories, highlighted persistent undertreatment issues among those with severe AS.

Aims: Recent studies suggest an association between cardiovascular disease (CVD) and cancer incidence/mortality, but the pathophysiological mechanisms underlying these associations are unclear. We aimed to examine biomarkers previously associated with CVD and study their association with incident cancer and cancer-related death in a prospective cohort study.

Methods And Results: We used a proteomic platform to measure 71 cardiovascular biomarkers among 5032 participants in the Framingham Heart Study who were free of cancer at baseline.

Background: Unnecessary hospitalizations may pose the risk of iatrogenic complications, suboptimal patient experience, and increased cost. Administrative data lack granularity to understand the proportion and causes of hospitalizations preventable through optimizing care continuum (HPOCC). We aim to identify the incidence and causes of HPOCC through clinician-adjudicated chart review.

We sought to investigate the utilization of prasugrel and its association with outcomes relative to clopidogrel in three typical subgroups of ACS in a real-world setting. Prasugrel is superior to clopidogrel for reducing risk of ischemic events in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI), but is associated with an increased risk of bleeding complications. PROMETHEUS was a retrospective multicenter observational study of 19,913 ACS patients undergoing PCI from 8 centers in the United States between 2010 and 2013.

The role of classroom learning in medical education is rapidly changing. To promote active learning and reduce student stress, medical schools have adopted policies such as pass/fail curriculums and recorded lectures. These policies along with the rising importance of the USMLE (United States Medical Licensing Examination) exams have made asynchronous learning popular to the detriment of classroom learning.

Shown in every neuroanatomy textbook, a key morphological feature is the bumpy ridges, which we refer to as hippocampal dentation, on the inferior aspect of the hippocampus. Like the folding of the cerebral cortex, hippocampal dentation allows for greater surface area in a confined space. However, examining numerous approaches to hippocampal segmentation and morphology analysis, virtually all published 3D renderings of the hippocampus show the inferior surface to be quite smooth or mildly irregular; we have rarely seen the characteristic bumpy structure on reconstructed 3D surfaces.

Background: Extranodal natural killer/T-cell lymphoma (ENKTL) usually presents as a localized disease in the nasal cavity; extension to the male genitourinary system is very rare and has been characterized only recently. Most cases present with predominantly extranodal involvement, advanced stage disease, highly aggressive course, and strong association with Epstein-Barr virus (EBV). While metastasis is common in ENKTLs, the penis is rarely involved in both nasal and non-nasal ENKTLs and only one report was published to date.
