KRAS mutations in pancreatic cancer: could we talk about a risk factor for the development of thromboembolic phenomena?

The oncogenic KRAS mutation is associated with increased tissue factor expression and thus hypercoagulability. In this regard, numerous studies published in the last decade have shown that KRAS mutations are an important risk factor for the development of thromboembolic phenomena in neoplasms of the digestive tract, such as colorectal cancer. On the other hand, some recently published studies suggest that KRAS mutations are also associated with an increased risk of developing thromboembolic phenomena in pancreatic cancer. Based on these premises, we have conducted a single-centre retrospective study on a cohort of patients with pancreatic cancer. Our aim is to demonstrate whether there is an association between the presence of KRAS mutations in our cohort of pancreatic cancer patients and an increased risk of developing thromboembolic phenomena.

Acute pancreatitis associated with levofloxacin.

According to some series, 0.3-1.5% of all cases of acute pancreatitis are drug induced. Acute pancreatitis due to levofloxacin is included in its safety data sheet as an adverse effect.

A bull horn fragment found on colonoscopy.

An 81-year-old man with mild iron deficiency anemia (Hb 12 g/dl) and a positive fecal occult blood test was referred for a colonoscopy. The patient was asymptomatic and not undergoing any treatment. A foreign body that crossed the colonic lumen and prevented the colonoscope progression was identified at 40 cm from the anal verge via colonoscopy. The object seemed to be hard and fixed when manipulated with biopsy forceps.

Adherence to patient blood management strategy in patients with gastrointestinal bleeding: a prospective nationwide multicenter study.

INTRODUCTION: Patient blood management (PBM) adherence in clinical practice is unclear. This real-world practice study assessed the management of patients with gastrointestinal (GI) bleeding after the implementation of the PBM strategy. METHODS: This was a nationwide multicenter and prospective study involving consecutive adults with GI bleeding between March 2019 and March 2021. Patients were examined according to hemoglobin (Hb) level at admission (<7 g/dl, n = 93; 7-8 g/dl, n = 47; 8-9 g/dl, n = 61; and >9 g/dl, n = 249). Study outcomes measures were morbidity and mortality during hospitalization and at 3- and 6-month follow-up. Appropriate anemia or iron deficiency management was considered when adherence to PBM policy was higher than 75%. RESULTS: A total of 450 patients (57.6% men, median age: 74 years, interquartile range: 63-82) were included. Overall, 55.1% and 59.3% of patients received transfusion and iron supplementation, respectively. The rates of appropriate transfusion and iron supplementation adherence were 90.9% (range: 86.9-93.5%, P = 0.109) and 81.8% (range: 78.5-85.1%, P = 0.041), depending on Hb level, respectively. No associations were observed between adherence to the PBM strategy and length of stay (P = 0.263) or risk of further bleeding (P = 0.742). Patients who were transfused [hazard ratio (HR): 0.79, 95% confidence interval (CI): 0.27-0.85] and iron supplemented (HR: 0.91, 95% CI: 0.38-1.41), however, appropriately achieved a lower risk of death. Age (HR: 1.12, 95% CI: 1.12-1.25) and further bleeding (HR: 39.08, 95% CI: 4.01-181.24) were poor prognostic factors. No serious adverse events were reported. CONCLUSIONS: In this nationwide study, there is a high level of adherence and safety of PBM for the treatment of GI bleeding. Adherence to the PBM strategy improved outcomes in patients with GI bleeding.
