Patient-Reported Work Ability During the First Two Years After Rectal Cancer Diagnosis

BACKGROUND: Rectal cancer treatment is associated with substantial short- and longer-term morbidity that may affect patients' ability to work. OBJECTIVE: We evaluated patient-reported work ability during the first 2 years after rectal cancer diagnosis, relative to the Dutch general population. Also, we assessed the association between clinical factors and work ability. DESIGN: This is a prospective cohort study. SETTINGS: This study was conducted at the Radiation-Oncology Department of a tertiary center. PATIENTS: Patients with rectal cancer, <67 years of age, and treated with curative intent were selected. MAIN OUTCOME MEASURES: Work ability was assessed with the Work Ability Index before the start of treatment (baseline) and at 3, 6, 12, 18, and 24 months after. The Work Ability Index scores of patients with paid employment were compared with the scores of matched population controls. Mixed models were used to estimate the impact of clinical factors on work ability. RESULTS: Of the 230 eligible patients, 172 (75%) had paid employment. Work ability decreased at 3 and 6 months compared with baseline. At 12 months, work ability recovered to baseline level but remained significantly lower than in population controls up to 24 months. Fifty-four percent reported 100 to 365 days of sick leave during the first 12 months of treatment versus 2% in the general population. At 24 months, 32% needed substantial adaptations in work activities, worked reduced hours, or were unable to work due to the disease versus 6% in the general population. Female sex, multiple comorbidities, oligometastatic disease, chemoradiation, and abdominoperineal resection were associated with lower work ability. LIMITATIONS: The study was limited by a decrease in questionnaire response rate from 83% to 64% over time. CONCLUSIONS: Patient-reported work ability deteriorates during rectal cancer treatment. Within 24 months after diagnosis, work ability returns to pretreatment level but remains lower than that of the general population. See Video Abstract at http://links.lww.com/DCR/B175. CAPACIDAD DE TRABAJO REPORTADO POR PACIENTES DURANTE LOS PRIMEROS DOS AÑOS DESPUÉS DEL DIAGNÓSTICO DE CÁNCER RECTAL ANTECEDENTES: El tratamiento del cáncer rectal se asocia con una morbilidad significante a corto y largo plazo que puede afectar la capacidad de trabajo de pacientes. OBJETIVO: Evaluamos la capacidad de trabajo reportado por pacientes durante los primeros dos años después del diagnóstico de cáncer rectal, en relación con la población general holandesa. Además, evaluamos la asociación entre los factores clínicos y capacidad para trabajar. DISEÑO: Estudio de cohorte prospectivo. ENTORNO CLINICO: Este estudio se realizó en el Departamento de Radiación Oncológica de en un centro de referencia de tercer nivel. PACIENTES: Se seleccionaron pacientes con cáncer rectal, <67 años de edad, y tratados con intención curativa. PRINCIPALES MEDIDAS DE RESULTADO: La capacidad de trabajo se evaluó con el índice de capacidad de trabajo antes del inicio del tratamiento (línea de base) y a los 3, 6, 12, 18 y 24 meses después. Los puntajes de capacidad laboral de los pacientes con empleo remunerado se compararon con los puntajes de los controles de población pareados. Se utilizaron modelos mixtos para estimar el impacto de los factores clínicos en la capacidad laboral. RESULTADOS: De los 230 pacientes elegibles, 172 (75%) tenían empleo remunerado. La capacidad de trabajo disminuyó a los 3 y 6 meses en comparación con la línea de base. A los 12 meses, la capacidad de trabajo se recuperó al nivel de referencia, pero se mantuvo significativamente más baja que en los controles de la población hasta 24 meses. Durante los primeros 12 meses, el 54% reportó 100-365 días de baja por enfermedad versus el 2% en la población general. A los 24 meses, el 32% necesitaba adaptaciones sustanciales en las actividades laborales, trabajó horas reducidas o no pudo trabajar debido a la enfermedad frente al 6% en la población general. El sexo femenino, las comorbilidades múltiples, la enfermedad oligometastásica, la quimiorradiación y la resección abdominoperineal se asociaron con una menor capacidad de trabajo. LIMITACIONES: El estudio estuvo limitado por una disminución en la tasa de respuesta al cuestionario del 83% al 64% a lo largo plazo. CONCLUSIONES: La capacidad laboral informada por el paciente se deteriora durante el tratamiento del cáncer rectal. Dentro de los 24 meses posteriores al diagnóstico, la capacidad laboral vuelve al nivel de pretratamiento, pero sigue siendo inferior a la de la población general.

3D black blood VISTA vessel wall cardiovascular magnetic resonance of the thoracic aorta wall in young, healthy adults: reproducibility and implications for efficacy trial sample sizes: a cross-sectional study

Background: Pre-clinical detection of atherosclerosis enables personalized preventive strategies in asymptomatic individuals. Cardiovascular magnetic resonance (CMR) has evolved as an attractive imaging modality for studying atherosclerosis in vivo. Yet, the majority of aortic CMR studies and proposed sequences to date have been performed at 1.5 tesla using 2D BB techniques and a slice thickness of 4-5 mm. Here, we evaluate for the first time the reproducibility of an isotropic, T1-weighted, three-dimensional, black-blood, CMR VISTA sequence (3D-T1-BB-VISTA) for quantification of aortic wall characteristics in healthy, young adults. Methods: In 20 healthy, young adults (10 males, mean age 31.3 years) of the AMBITYON cohort study the descending thoracic aorta was imaged with a 3.0 T MR system using the 3D-T1-BB-VISTA sequence. The inter-scan, inter-rater and intra-rater reproducibility of aortic lumen, total vessel and wall area and mean and maximum wall thickness was evaluated using Bland-Altman analyses and Intraclass Correlation Coefficients (ICC). Based on these findings, sample sizes for detecting differences in aortic wall characteristics between groups were calculated. Results: For each studied parameter, the inter-scan, inter-rater and intra-rater reproducibility was excellent as indicated by narrow limits of agreement and high ICCs (ranging from 0.76 to 0.99). Sample sizes required to detect a 5 % difference in aortic wall characteristics between two groups were 203, 126, 136, 68 and 153 per group for lumen area, total vessel area and vessel wall area and for mean and maximum vessel wall thickness, respectively. Conclusion: The 3D-T1-BB-VISTA sequence provides excellent reproducibility for quantification of aortic wall characteristics and can detect small differences between groups with reasonable sample sizes. Hence, it may be a valuable tool for assessment of the subtle vascular wall changes of early atherosclerosis in asymptomatic populations

Preoperative unintended weight loss and low body mass index in relation to complications and length of stay after cardiac surgery

BACKGROUND: Several studies reported increased adverse outcomes after cardiac surgery in patients with low body mass index (BMI; in kg/m(2)). Little is known yet, however, about the effect of preoperative unintended weight loss (UWL) in cardiac surgery patients. OBJECTIVE: We explored the prevalence and effect of UWL in view of low BMI and vice versa adjusted for a validated set of preoperative risks, inflammatory activity, and duration of extracorporeal circulation on postoperative adverse outcome. DESIGN: A prospective cohort study was performed. Nutritional data of cardiac surgery patients were collected within 24 h of admission and linked to the standard postoperative complication registration database. RESULTS: The cohort consisted of 331 cases. Multivariate logistic regression analyses showed that preoperative UWL of >or=10% in the past 6 mo (>or=10%UWLin6m) was associated with a prolonged length of stay in the hospital independent from low BMI [odds ratio (OR): 7.06; 95% CI: 1.78, 28.04]. Preoperative BMI or=10%UWLin6m (OR: 4.62; 95% CI: 1.20, 17.82; and OR: 5.27; 95% CI: 1.28, 21.76, respectively). Preoperative undernutrition in cardiac surgery patients (>or=10%UWLin6m or BMI or=10%UWLin6m or BMI <or= 21.0 because both variables are independently related to adverse outcomes. Preoperative referral to a dietitian for further diagnostic assessment and nutritional treatment is strongly recommende

Reference Values for Cardiac and Aortic Magnetic Resonance Imaging in Healthy, Young Caucasian Adults.

Reference values for morphological and functional parameters of the cardiovascular system in early life are relevant since they may help to identify young adults who fall outside the physiological range of arterial and cardiac ageing. This study provides age and sex specific reference values for aortic wall characteristics, cardiac function parameters and aortic pulse wave velocity (PWV) in a population-based sample of healthy, young adults using magnetic resonance (MR) imaging.In 131 randomly selected healthy, young adults aged between 25 and 35 years (mean age 31.8 years, 63 men) of the general-population based Atherosclerosis-Monitoring-and-Biomarker-measurements-In-The-YOuNg (AMBITYON) study, descending thoracic aortic dimensions and wall thickness, thoracic aortic PWV and cardiac function parameters were measured using a 3.0T MR-system. Age and sex specific reference values were generated using dedicated software. Differences in reference values between two age groups (25-30 and 30-35 years) and both sexes were tested.Aortic diameters and areas were higher in the older age group (all p<0.007). Moreover, aortic dimensions, left ventricular mass, left and right ventricular volumes and cardiac output were lower in women than in men (all p<0.001). For mean and maximum aortic wall thickness, left and right ejection fraction and aortic PWV we did not observe a significant age or sex effect.This study provides age and sex specific reference values for cardiovascular MR parameters in healthy, young Caucasian adults. These may aid in MR guided pre-clinical identification of young adults who fall outside the physiological range of arterial and cardiac ageing

Predictors of Knowledge and Image Interpretation Skill Development in Radiology Residents

Purpose To investigate knowledge and image interpretation skill development in residency by studying scores on knowledge and image questions on radiology tests, mediated by the training environment. Materials and Methods Ethical approval for the study was obtained from the ethical review board of the Netherlands Association for Medical Education. Longitudinal test data of 577 of 2884 radiology residents who took semiannual progress tests during 5 years were retrospectively analyzed by using a nonlinear mixed-effects model taking training length as input variable. Tests included nonimage and image questions that assessed knowledge and image interpretation skill. Hypothesized predictors were hospital type (academic or nonacademic), training hospital, enrollment age, sex, and test date. Results Scores showed a curvilinear growth during residency. Image scores increased faster during the first 3 years of residency and reached a higher maximum than knowledge scores (55.8% vs 45.1%). The slope of image score development versus knowledge question scores of 1st-year residents was 16.8% versus 12.4%, respectively. Training hospital environment appeared to be an important predictor in both knowledge and image interpretation skill development (maximum score difference between training hospitals was 23.2%; P < .001). Conclusion Expertise developed rapidly in the initial years of radiology residency and leveled off in the 3rd and 4th training year. The shape of the curve was mainly influenced by the specific training hospital. (©) RSNA, 2017 Online supplemental material is available for this article
