Colorectal Cancer Screening.

Colorectal cancer (CRC) continues to be one of the most commonly diagnosed cancers and contributes significantly to many cancer-related deaths despite sustained progress in diagnostic and treatment options. Many forms of CRC can be prevented through early and routine screening, when precancerous lesions may be detected and removed before they undergo malignant transformation or metastasis. Despite widespread efforts to improve CRC screening rates, at least 40% of age-eligible adults do not adhere to screening guidelines.

Extensive Bone Reaction From Catastrophic Oxidized Zirconium Wear.

The use of alternative bearing surfaces for total hip arthroplasty has become popular to minimize wear and increase longevity, especially in young patients. Oxidized zirconium (Oxinium; Smith & Nephew, Memphis, Tennessee) femoral heads were introduced in the past decade for use in total hip arthroplasty. The advantages of oxidized zirconium include less risk of fracture compared with traditional ceramic heads.

Predictors of malignancy in patients with suspicious or indeterminate cytology on pancreatic endoscopic ultrasound-guided fine-needle aspiration: a multivariate model.

Objective: The aim of this study was to evaluate predictors of malignancy in pancreatic lesions with suspicious or indeterminate endoscopic ultrasound fine-needle aspiration (EUS-FNA) cytology.

Methods: Suspicious/indeterminate EUS-FNA cytology was identified from our database. Stable imaging, benign pathology, or survival for 12 months after EUS-FNA was considered benign.

A pilot study to evaluate the feasibility of implementing a split-dose bowel preparation for inpatient colonoscopy: a single-center experience.

Objectives: Feasibility of using split-dose bowel preparation in an inpatient setting has not been extensively studied. We conducted a single-centre multiphase study to (1) understand the perceived barriers to split-dose administration among nursing and providers, (2) develop and implement a split-dose electronic order set and (3) evaluate the use and impact of split-dose administration on 100 consecutive colonoscopies.

Methods: Nurse/provider interviews were conducted to understand perceived concerns and potential barriers to split-dose preparation.

Prospective evaluation of the long-term outcomes after deep small-bowel spiral enteroscopy in patients with obscure GI bleeding.

Background: Spiral enteroscopy can be safe and effective in the short term for evaluation of obscure GI bleeding, but long-term data are lacking.

Objective: To assess the long-term clinical outcomes after deep small-bowel spiral enteroscopy performed for obscure GI bleeding.

Design: Prospective cohort study.

Randomized, controlled trial of standard, large-capacity versus jumbo biopsy forceps for polypectomy of small, sessile, colorectal polyps.

Background: Polypectomy with cold biopsy forceps is a frequently used technique for removal of small, sessile, colorectal polyps. Jumbo forceps may lead to more effective polypectomy because of the larger size of the forceps cup.

Objective: To evaluate the efficiency of cold jumbo biopsy forceps compared with standard forceps for polypectomy of small, sessile, colorectal polyps.

Algorithm for the management of endoscopic perforations: a quality improvement project.

Perforations are an uncommon but serious complication of endoscopy. Although they are well recognized, no universally accepted strategy for their management exists. The need for management algorithms in situations that call for multiple interventions in a short time, with coordinated effort encompassing multiple providers from different specialties, has long been recognized, but no such clinical care pathway has been developed for the management of endoscopic perforations.

The utility of repeat endoscopic ultrasound-guided fine needle aspiration for suspected pancreatic cancer.

Background. The utility of repeat EUS in patients with suspicion for pancreatic cancer after non-diagnostic EUS-FNA study is not well established. Aim.

Diagnostic value of noninvasive combined fluorine-18 labeled fluoro-2-deoxy-D-glucose positron emission tomography and computed tomography enterography in active Crohn's disease.

Background: The role of combined localized positron emission tomography (lPET) and computed tomography enterography (CTe) in Crohn's disease is unclear. We examined if this imaging modality using fluorine-18 labeled-fluoro-2-deoxy-D-glucose (FDG) could more effectively identify disease activity.

Methods: 52 lPET-CTe scans were analyzed in this retrospective study.

Erythromycin improves gastric emptying half-time in adult cystic fibrosis patients with gastroparesis.

Background: Gastrointestinal manifestations are frequently encountered in cystic fibrosis patients. Gastroparesis evidenced by a variety of diagnostic methods has been described in patients with cystic fibrosis, predominantly in children and in individuals with advanced lung disease. The presence of gastroparesis in adult patients with different degrees of lung involvement and its response to the acute and chronic administration of macrolides have not been reported.

The 90/90 pillow reduces blood loss after knee arthroplasty: a prospective randomized case control study.

Our goal was to evaluate the 90/90 pillow as an effective means of preventing blood loss after knee arthroplasty. We performed a prospective randomized case-control study on 40 patients undergoing knee arthroplasty. All patients were treated in a standard fashion, except for the use of the 90/90 pillow in one group.

Species separation of Taxus baccata, T. canadensis, and T. cuspidata (Taxaceae) and origins of their reputed hybrids inferred from RAPD and cpDNA data.

Species delimitation in Taxus (Taxaceae) has been controversial due to high levels of phenotypic plasticity. Reputed hybrids between species have been questioned due to the original crosses' accidental nature and the uncertainty regarding the parent species' distinctness. In this study 19 samples from three species (T.
