Background/aim: Desmoid tumors (DTs), or aggressive fibromatosis, are rare neoplasms arising from connective tissue, frequently exhibiting local invasiveness. The limited treatment options and high recurrence rates of DTs highlight the need for novel therapeutic strategies. This study investigated the efficacy of chlorhexidine dihydrochloride (CD) in inhibiting the growth of DTs and colorectal cancer (CRC).

Background/aim: Desmoid tumors (DTs), also referred to as aggressive fibromatosis, originate from connective tissues and typically manifest with a propensity for local invasion. Despite extensive research efforts aimed at exploring novel anti-tumor agents for DTs, the development of effective clinical management strategies remains an ongoing challenge due to the limited success of current treatments, which frequently lead to inconsistent outcomes and a high recurrence rate of DTs. To overcome these limitations, we focused our research aim on a drug repositioning approach to identify existing medications that could be effective against DTs.

Backgrounds: High-intensity statin is recommended for patients undergoing percutaneous coronary intervention (PCI), and ezetimibe is recommended to be added in patients not achieving low-density lipoprotein cholesterol (LDL-C) targets. Moderate-intensity statin plus ezetimibe can reduce LDL-C levels similar to high-intensity statin. The aim of this study is to examine the long-term efficacy and safety of moderate-intensity statin plus ezetimibe as the first-line strategy compared to high-intensity statin in patients undergoing PCI.

Article Synopsis
  • A study called the THRIVE trial is looking at how exercise can help Hispanic/Latinx and Black cancer patients who are getting chemotherapy and might not be very active.
  • The trial includes 45 patients who are split into three groups: one gets supervised exercise at home, another exercises on their own, and the last group does stretching exercises.
  • Researchers will check how much exercise the patients do and other health factors before, during, and after the 16-week program to see what works best.

Creeping fat (CrF) is an extraintestinal manifestation observed in patients with Crohn's disease (CD). It is characterized by the accumulation of mesenteric adipose tissue (MAT) that wraps around the intestinal wall. Although the role of CrF in CD is still debated, multiple studies have highlighted a correlation between CrF and inflammation, as well as fibrostenosais of the intestine, which contributes to the worsening of CD symptoms.
