Introduction: Stroke is the second most common cause of mortality worldwide. Data regarding the predictors of mortality of acute ischemic stroke are widely discordant. Identifying the predictors and providing the utmost care to a high-risk patient is still an unmet need in middle- to low-income countries. We did this study to identify the predictor of in-hospital mortality of acute ischemic stroke. Materials and Methods: We conducted a retrospective study of patients with acute ischemic stroke presented to the tertiary care center in eastern Nepal from January 2012 to December 2016...

Background and aims Precut papillotomy is widely used after failed biliary cannulation. Endoscopic ultrasound (EUS)-guided biliary access techniques are newer methods to facilitate access and therapy in failed cannulation. We evaluated the impact of EUS-guided biliary access on endoscopic retrograde cholangiopancreatography (ERCP) success and compared these techniques to precut papillotomy. Patients and methods We retrospectively compared two ERCP cohorts. One cohort consisted of biliary ERCPs (n = 1053) attempted in patients with native papillae and surgically unaltered anatomy in whom precut papillotomy and/or EUS-guided biliary access were routinely performed immediately after failed cannulation...

The aim of this paper is to present several popular methods for in vitro culture of osteocytes and osteocyte cell lines. Osteocytes are located extremely suitably within the calcified bone matrix to sense mechanical signals, and are equipped with a multitude of molecular features that allow mechanosensing. However, osteocytes are more than specialized mechanosensing cells. Several signaling molecules are preferentially produced by osteocytes, and osteocytes hold a tight reign over osteoblast and osteoclast formation and activity, but also have a role as endocrine cell, communicating with muscles or organs as remote as the kidneys...

BACKGROUND AND AIMS: Endoscopic resection (ER) is an efficacious treatment for complex colon polyps (CCPs). Many patients are referred for surgical resection because of concerns over procedural safety, incomplete polyp resection, and adenoma recurrence after ER. Efficacy data for both resection strategies are widely available, but a paucity of data exist on the cost-effectiveness of each modality. The aim of this study was to perform an economic analysis comparing ER and laparoscopic resection (LR) strategies in patients with CCP...

BACKGROUND & AIMS: Plastic stents, placed via endoscopy to drain pancreatic fluid collections (PFCs), require repeat access. Covered metal stents are larger in diameter and can be inserted in a single step, but can migrate. We evaluated the safety and efficacy of a lumen-apposing, covered, self-expanding metal stent (LACSEMS) for PFC drainage. METHODS: We performed a prospective study of the outcomes of stent placement in 33 patients (18 men; age, 53 ± 14 y; 28 with chronic pancreatitis) with symptomatic pancreatic pseudocysts and walled-off necrosis (≥ 6 cm with ≥ 70% fluid content)...
