A Light Touch: Solar Photocatalysis Detoxifies Oil Sands Process-Affected Waters Prior to Significant Treatment of Naphthenic Acids.

Environmental reclamation of Canada's oil sands tailings ponds is among the single largest water treatment challenges globally. The toxicity of oil sands process-affected water (OSPW) has been associated with its dissolved organics, a complex mixture of naphthenic acid fraction components (NAFCs). Here, we evaluated solar treatment with buoyant photocatalysts (BPCs) as a passive advanced oxidation process (P-AOP) for OSPW remediation.

Altered aortic shape in bicuspid aortic valve relatives influences blood flow patterns.

Aims: Bicuspid aortic valve (BAV) is known to exhibit familial inheritance and is associated with aortopathy and altered aortic haemodynamics. However, it remains unclear whether BAV-related aortopathy can be inherited independently of valve morphology.

Methods And Results: Four-dimensional flow magnetic resonance imaging for the in vivo assessment of thoracic aortic 3D blood flow was performed in 24 BAV relatives with trileaflet aortic valves (age = 40 ± 14 years) and 15 healthy controls (age = 37 ± 10 years).

Understanding Why Residents May Inaccurately Log Their Role in Operations: A Look at the 2013 In-Training Examination Survey.

Background: With increased time and quality pressures, it may be more difficult for residents in cardiothoracic surgery residency programs to get independent operative experience. That may lead residents to inaccurately report their role as "surgeon" to meet American Board of Thoracic Surgery (ABTS) case requirements.

Methods: The 2013 In-Training Examination surveyed 312 cardiothoracic surgery residents and was used to contrast residents in traditional 2-year and 3-year cardiothoracic surgery residencies (traditional, n = 216) with those in 6-year integrated or 3+4-year programs (integrated, n = 96).

A Decade of Change: Training and Career Paths of Cardiothoracic Surgery Residents 2003 to 2014.

Background: During the past decade, cardiothoracic surgery (CTS) education has undergone tremendous change with the advent of new technologies and the implementation of integrated programs, to name a few. The goal of this study was to assess how residents' career paths, training, and perceptions changed during this period.

Methods: The 2006 to 2014 surveys accompanying the Thoracic Surgery Residents Association/Thoracic Surgery Directors' Association in-training examination taken by CTS residents were analyzed, along with a 2003 survey of graduating CTS residents.

Predictors of Career Choice Among Cardiothoracic Surgery Trainees.

Background: The impact of factors influencing career choice by cardiothoracic surgery (CTS) trainees remains poorly defined in the modern era. We sought to examine the associations between CTS trainee characteristics and future career aspirations.

Methods: The 2012 Thoracic Surgery In-Training Examination survey results were used to categorize responders according to career interest: congenital, adult cardiac, mixed cardiac/thoracic, and general thoracic surgery.
