In recent years, therapeutic endoscopy has become a fundamental tool in the management of gallbladder diseases in light of its minimal invasiveness, high clinical efficacy, and good safety profile. Both endoscopic transpapillary gallbladder drainage (TGBD) and endoscopic ultrasound (EUS)-guided gallbladder drainage (EUS-GBD) provide effective internal drainage in patients with acute cholecystitis unfit for cholecystectomy, avoiding the drawbacks of external percutaneous gallbladder drainage (PGBD). The availability of dedicated lumen-apposing metal stents (LAMS) for EUS-guided transluminal interventions contributed to the expansion of endoscopic therapies for acute cholecystitis, making endoscopic gallbladder drainage easier, faster, and hence more widely available.

Int J Mol Sci

February 2024

Departamento de Medicina y Psiquiatría, Instituto de Investigación Sanitaria Valdecilla (IDIVAL), Facultad de Medicina, Universidad de Cantabria, 39011 Santander, Spain.

Article Synopsis
  • - This study examines genetic factors linked to atypical femoral fractures (AFF), which occur in patients on long-term anti-resorptive therapy, focusing on specific genes related to bone health.
  • - Analysis of 13 AFF patients revealed only one with a pathogenic gene variant (ALPL), but significantly more genetic variants were found in AFF patients compared to those without AFF, especially in genes associated with bone formation.
  • - The findings suggest that a combination of genetic variants influences the risk of AFF, highlighting specific genes (ACAN, SUCO, AKAP13, ARHGEF3, PITX2, P4HB) as potential risk factors, warranting larger studies for effective patient risk assessment.
