Manufacturing and Joining PP/NBR Blends in the Presence of Dual Compatibilizer and Halloysite Nanotubes.

Polypropylene (PP)/acrylonitrile butadiene rubber (NBR) composite plates reinforced with halloysite nanotubes (HNTs) were manufactured in the presence of dual compatibilizers: PP-grafted maleic anhydride (PP-g-MA) and styrene ethylene butylene styrene-grafted maleic anhydride (SEBS-g-MA). The mechanical characteristics and microstructure of the PP/NBR/HNT nanocomposites were investigated as a function of NBR content (10, 20, and 30 wt.%) and HNTs content (3, 5, and 7 wt.

Upper gastrointestinal bleeding following transcatheter aortic valve replacement: A retrospective analysis.

Objectives: The aim of this study was to identify the incidence of upper gastrointestinal bleeding (UGIB) in the postprocedural period following transcatheter aortic valve replacement (TAVR).

Background: As TAVR moves into intermediate- and low-risk patients, it has become increasingly important to understand its extracardiac complications. The patient population undergoing TAVR have clinical and demographic characteristics that place them at significant risk of UGIB.

Body mass index and body surface area and their associations with outcomes in stage II and III colon cancer.

Background: Our study aims were to measure the associations between body mass index (BMI) and body surface area (BSA) with outcomes for stage II and III colon cancer and to evaluate if the effect of obesity is modified by disease stage and receipt of adjuvant therapy.

Methods: Using a prospective cohort of stage II and III colon cancer patients who were referred between 2001 and 2005, we compared 3-year relapse-free survival (3-year RFS), 5-year cancer-specific survival (5-year CSS), and 5-year overall survival (5-year OS) rates among different BMI and BSA categories. Cox proportional-hazards models were constructed to explore the relationships between different body compositions and outcomes while adjusting for confounders.

Transition from cognitively impaired not demented to Alzheimer's disease: an analysis of changes in functional abilities in a dementia clinic cohort.

Background: Patients with cognitive impairment no dementia (CIND) are at an increased risk of progression to Alzheimer's disease (AD). Whether subtle impairments in functional or social abilities at the CIND stage can predict progression to AD is not yet fully determined. We evaluated whether impairments on the Disability Assessment for Dementia (DAD) and Functional Rating Scale (FRS) can predict progression to AD.
