Breaking Down Barriers to Detection and Care in Early-Age-Onset Colorectal Cancer in Canada.

The second Early-Age-Onset Colorectal Cancer Symposium, convened in October 2022, sought solutions to the barriers to early detection and care for colorectal cancer in Canada. This meeting built on a previous symposium, held in 2021 and reported in this journal. Early-age-onset colorectal cancer (EAOCRC) affects increasing numbers of people under the age of 50 in Canada and throughout the developed world. Two main themes emerged from the meeting: the importance of timely detection, and the need for a tailored approach to the care of EAOCRC. Early detection is crucial, especially in light of the later stage at diagnosis and unique tumour characteristics. Symposium participants were strongly in favour of reducing the age of eligibility for screening from 50 to 45, and promoting the development of non-invasive screening techniques such as testing for circulating tumour DNA and biomarkers. Leading approaches to care were described and discussed, which meet the unique treatment needs of younger CRC patients. Multidisciplinary practices within and outside Canada address such factors as fertility, family roles, education, careers and financial responsibilities. These models can be applied in treatment centres across the country.

Early-Age-Onset Colorectal Cancer in Canada: Evidence, Issues and Calls to Action.

The inaugural Early-Age-Onset Colorectal Cancer Symposium was convened in June 2021 to discuss the implications of rapidly rising rates of early-age-onset colorectal cancer (EAO-CRC) in Canadians under the age of 50 and the impactful outcomes associated with this disease. While the incidence of CRC is declining in people over the age of 50 in Canada and other developed countries worldwide, it is significantly rising in younger people. Canadians born after 1980 are 2 to 2.5 times more likely to be diagnosed with CRC before the age of 50 than previous generations at the same age. While the etiology of EAO-CRC is largely unknown, its characteristics differ in many key ways from CRC diagnosed in older people and warrant a specific approach to risk factor identification, early detection and treatment. Participants of the symposium offered directions for research and clinical practice, and developed actionable recommendations to address the unique needs of these individuals diagnosed with EAO-CRC. Calls for action emerging from the symposium included: increased awareness of EAO-CRC among public and primary care practitioners; promotion of early detection programs in younger populations; and the continuation of research to identify unique risk factor profiles, tumour characteristics and treatment models that can inform tailored approaches to the management of EAO-CRC.

Barriers to and facilitators of return to learning following a sport-related concussion: Perspectives of female secondary school students.

OBJECTIVE: To identify barriers to and facilitators of return to learning (RTL) for female secondary school students following a sport-related concussion (SRC), and to identify critical junctures on the injury-to-recovery continuum that can be targeted to enhance the RTL process. DESIGN: A grounded theory approach using in-depth qualitative interviews. SETTING: Secondary schools within the York Region District School Board in Ontario. PARTICIPANTS: Ten female secondary school students who presented to a sports medicine physician with an SRC in 2015 or 2016. Five of the students received a Green Folder intervention containing an RTL strategy, while 5 students received no RTL intervention following their SRC. METHODS: In-depth interviews were conducted in person or by telephone. All interviews were audiorecorded and transcribed. The transcriptions were analyzed, coded, and examined for common themes by 2 independent reviewers. MAIN FINDINGS: Barriers to RTL included a lack of a graduated RTL process, students' own internal stress, poor communication of expectations, lack of concussion education, and inadequate support from teachers. Facilitators of RTL included academic accommodations and having a primary contact person within the school system. Owing to inconsistent implementation, the impact of the Green Folder intervention as a facilitator of RTL remains unknown. CONCLUSION: Results of this study support existing findings in the realm of concussion research. A novel finding includes the importance of a primary contact person as a facilitator of RTL. This person could help to overcome some of the identified barriers to RTL and improve outcomes by assisting with academic accommodations, providing reassurance regarding these accommodations, improving education among teachers and students, and enhancing communication between stakeholders.

Does routine ultrasound change management in the follow-up of patients with vesicoureteral reflux?

INTRODUCTION: Children with vesicoureteral reflux (VUR) usually need a renal ultrasound (RUS). There is little data on the role of follow-up RUS in VUR. We evaluated the impact of follow-up RUS on the change in clinical management in patients with VUR. METHODS: We prospectively analyzed children with a previous diagnosis of VUR seen in the outpatient clinic with a routine follow-up RUS within 4 months. Variables collected included: demographic data, VUR history, dysfunctional voiding symptoms and concurrent ultrasound findings. Change in management was defined as addition of new medication, nurse counselling, surgery or further investigations. RESULTS: The study included 114 consecutive patients. The mean patient age was 4.5 years old, mean age of VUR diagnosis was 1.7 years, with average follow-up of 2.8 years. A change in management with stable RUS occurred in 14 patients, in which the change included ordering a DMSA in 9, nurse counselling for dysfunctional voiding in 3, and booking surgery in 2 patients. Change on RUS was seen in 4 patients. Multivariable analysis showed that history of urinary tract infection (UTI) since the last follow-up visit was more significant than RUS findings. CONCLUSIONS: The RUS findings in most patients followed for VUR remain stable or with minimal changes. The variable showing a significant effect on change in management in our study was history of UTI since the last follow-up visit rather than RUS findings. The value of follow-up RUS for children with VUR may need to be revisited.

Psychological screening measures for cosmetic plastic surgery patients: a systematic review.

With the increasing popularity of cosmetic surgery procedures, preoperative psychological assessment of cosmetic surgery patients may improve outcomes by highlighting patient expectations and motivations, as well as by identifying those who may require psychological referral. In this article, the authors describe a systematic literature review to identify and evaluate current self-report tools used in the psychological screening of cosmetic surgery patients prior to surgery. Articles related to the preoperative mental health assessment of cosmetic surgery patients were identified by searching MEDLINE, EMBASE, HAPI, CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials through November 2010. The full text of potentially relevant articles was examined by 2 reviewers, and articles that met the inclusion criteria were reported. Close reading of 100 full-text articles showed that although a variety of instruments are currently being used as preoperative assessment tools, there are limitations to their validity and usefulness in the screening of cosmetic surgery patients. To properly assess cosmetic surgery patients, a scientifically sound and clinically useful instrument is needed.

Imaging biomarker dynamics in an intracranial murine glioma study of radiation and antiangiogenic therapy.

PURPOSE: There is a growing need for noninvasive biomarkers to guide individualized spatiotemporal delivery of radiation therapy (RT) and antiangiogenic (AA) therapy for brain tumors. This study explored early biomarkers of response to RT and the AA agent sunitinib (SU), in a murine intracranial glioma model, using serial magnetic resonance imaging (MRI). METHODS AND MATERIALS: Mice with MRI-visible tumors were stratified by tumor size into 4 therapy arms: control, RT, SU, and SU plus RT (SURT). Single-fraction conformal RT was delivered using MRI and on-line cone beam computed tomography (CT) guidance. Serial MR images (T2-weighted, diffusion, dynamic contrast-enhanced and gadolinium-enhanced T1-weighted scans) were acquired biweekly to evaluate tumor volume, apparent diffusion coefficient (ADC), and tumor perfusion and permeability responses (K(trans), K(ep)). RESULTS: Mice in all treatment arms survived longer than those in control, with a median survival of 35 days for SURT (P<.0001) and 30 days for RT (P=.009) and SU (P=.01) mice vs 26 days for control mice. At Day 3, ADC rise was greater with RT than without (P=.002). Sunitinib treatment reduced tumor perfusion/permeability values with mean K(trans) reduction of 27.6% for SU (P=.04) and 26.3% for SURT (P=.04) mice and mean K(ep) reduction of 38.1% for SU (P=.01) and 27.3% for SURT (P=.02) mice. The magnitude of individual mouse ADC responses at Days 3 and 7 correlated with subsequent tumor growth rate R values of -0.878 (P=.002) and -0.80 (P=.01), respectively. CONCLUSIONS: Early quantitative changes in diffusion and perfusion MRI measures reflect treatment responses soon after starting therapy and thereby raise the potential for these imaging biomarkers to guide adaptive and potentially individualized therapy approaches in the future.
