BACKGROUND AND STUDY AIMS The approach to small bowel preparation before capsule endoscopy (CE) is still suboptimal. PATIENTS AND METHODS One hundred eighty patients were randomly allocated to 3 groups. Patients in Group A took 250 mL 20% mannitol and 1 L 0.9% saline orally at 05:00 hours on the day of the procedure. In Group B the same preparation was taken at 20:00 on the day before, and at...

Let p be a prime congruent to 1 modulo 4, and let t, u be rational integers such that (t + u √ p )/2 is the fundamental unit of the real quadratic field Q(√p ). The Ankeny-Artin-Chowla conjecture (AAC conjecture) asserts that p will not divide u. This is equivalent to the assertion that p will not divide B(p−1)/2, where Bn denotes the nth Bernoulli number. Although first published in 1952, this...

Abstract For treatment effects—one of the core issues in modern econometric analysis—prediction and estimation are two sides same coin. As it turns out, machine learning methods tool for generalized prediction models. Combined with theory, they allow us to estimate not only average but a personalized effect—the conditional effect (CATE). In this tutorial, we give an overview novel methods, expl...

BACKGROUND AND PURPOSE We review preliminary experience with patients harboring intracerebral hematoma (ICH) treated by stereotactic computed tomographic (CT) guided thrombolysis and aspiration and assess procedure feasibility and safety. METHODS Twelve patients with supratentorial ICH >/=25 mL without suspected underlying structural etiology or coagulopathy and an initial Glasgow Coma Scale ...

background despite significant advances in the treatment of chronic hepatitis c in the past decades, factors which can affect response rates to combination therapy; peginterferon and ribavirin, are still under study and reaching sustained virological response (svr) is affected by several different factors. objectives to investigate predictor factors contributing to svr in iranian patients. pati...

OBJECTIVE To assess the effect of high-dose vitamin D in patients with painful diabetic neuropathy. METHODS A single intramuscular dose of 600 000 IU vitamin D was administered, and the effects on metabolic parameters and neuropathic pain assessed over 20 weeks. RESULTS 143 participants with predominantly type 2 diabetes, aged 52.31±11.48 years, with a Douleur Neuropathique 4 (DN4) score (3...

Recurrent HCV infection following liver transplantation can lead to accelerated allograft injury that is difficult to treat with interferon. The aim of this study is to describe the first ever use of an interferon-free, all oral regimen in a liver transplant recipient with severe recurrent HCV. A 54-year-old male with HCV genotype 1b developed severe cholestatic HCV at 6 months posttransplant w...
