Aim: To examine the long-term therapeutic efficacies of endoscopic cauterization for gastric vascular ectasia, according to the type of lesion.

Methods: Thirty-eight patients with hemorrhagic gastric vascular ectasia (VE) were treated by endoscopic cauterization: 13 by heater probe coagulationand 25 by argon plasma coagulation. Depending on the number of lesions, 14 and 24 patients were classified into localized VE (≤ 10; LVE) and extensive VE (> 10; EVE), respectively. The patients were followed-up by repeated endoscopic examinations after the therapy, and the incidences of VE recurrence and re-bleeding from the lesions were evaluated.

Results: Although the VE lesions disappeared initially in all the patients after the therapy, the recurrence of VE developed in 25 patients (66%) over a mid-term observation period of 32 mo, and re-bleeding occurred in 15 patients (39%). The recurrence of VE was found in all patients with EVE, with re-bleeding occurring in 14 patients (58%). In contrast, only 1 patient (7%) with LVE showed recurrence of the lesions and complicating hemorrhage. Both the cumulative recurrence-free rates and cumulative re-bleeding-free rates were significantly lower in the EVE group than in the LVE group (P < 0.001 and P < 0.001, respectively). Moreover, the cumulative re-bleeding-free rate in the EVE group was 47.6% at 1 year and 25.4% at 2 years in patients with chronic renal failure, which were significantly lower than the rates in the patients without chronic renal failure (83.3% and 74.1%, respectively) (P < 0.05).

Conclusion: The recurrence of VE and re-bleeding from the lesions was more frequent in the patients with EVE, especially in those with complicating renal failure.

Purpose: Obesity and type 2 diabetes (T2DM) are major risk factors for hepatic steatosis. Diet or bariatric surgery can reduce liver volume, fat content, and inflammation. However, little is known about their effects on liver function, as evaluated here using the LiMAx test.

Gastric antral vascular ectasia is a frequent and potentially severe complication of systemic sclerosis. Management is presently limited to supportive care, acid suppression and endoscopic treatment. Many cases of gastric antral vascular ectasia tend to be refractory or partially responsive to standard treatment and require multiple endoscopic procedures to control the recurrent bleeding.

Background: There is controversy regarding which is the best reconstruction technique after the pancreatoduodenectomy. Currently, there are no studies comparing the three most frequent reconstruction techniques: Whipple + Roux-en-Y gastrojejunostomy (WRYGJ), pyloric-preserving + Billroth II (PPBII), and Whipple + BII (WBII).

Methods: Between 2012 and March 2023, 246 patients underwent pancreaticoduodenectomy with the following type of reconstruction techniques: (1) WRYGJ: 40 patients; (2) PPBII: 118 patients; and (3) WBII: 88 patients.

Enhanced Osteoporosis Treatment via Nano Drug Coating Encapsulating GG.

Osteoporosis is the most common systemic skeletal disorder, particularly associated with aging and postmenopausal women. With the growing knowledge about the gut-bone axis, the therapeutic strategies for osteoporosis have been shifted toward regulating gut microbiota to promote positive bone metabolism. Although GG (LGG) is widely reported to positively regulate bone metabolism by restoring the dysbiotic microbiome, oral administration is associated with sensitivity to gastric fluid and low bioavailability.

Arachidonic acid synergizes with aspirin preventing myocardial ischemia-reperfusion injury and mitigates bleeding risk.

Cardiovasc Res

Aims: The therapeutic efficacy of coronary revascularization is compromised by myocardial ischemia-reperfusion (MI/R) injury. Higher levels of circulating arachidonic acid (AA) are reportedly associated with lower risk of cardiovascular disease. The cyclooxygenase (COX) pathway metabolizes AA into prostaglandins (PGs) and the platelet-activating thromboxane A2 (TXA2), which is inhibited by aspirin.
