A prospective, observational cohort study comparing cancer clinical trial availability and enrollment between early adolescents/young adults and children.

ABSTRACT: BACKGROUND:Poor enrollment of adolescents and young adults (AYAs) (ages 15-39 years) onto cancer clinical trials (CCTs) may contribute to inferior survival gains compared with children. In this study, the authors assessed whether differences in CCT availability would explain lower CCT enrollment for early AYAs (eAYAs) (ages 15-21 years). METHODS:This prospective, observational cohort study was conducted at a single academic children's hospital. For consecutive patients who were newly diagnosed with cancer over a 13-month period, it was determined whether an appropriate CCT existed nationally or was available locally and whether enrollment on that CCT occurred. The proportions of eAYAs versus children in each category were compared using the chi-square test. The impact of age and other factors on enrollment status was assessed using logistic regression analysis. RESULTS:Among 216 patients, 58 were eAYAs, and 158 were children. There was no difference in the proportion of eAYAs versus children who had an existing CCT (28 of 58 eAYAs [48.3%] vs 85 of 158 children [53.8%]; P = .47) or an available CCT (23 of 58 eAYAs [39.7%] vs 75 of 158 children [47.5%]; P = .31). However, significantly fewer eAYAs were enrolled when a CCT was available (7 of 23 eAYAs [30.4%] vs 50 of 75 children [67.7%]; P = .002). In multivariable analysis, eAYAs were significantly less likely than children to be enrolled in an available CCT (adjusted odds ratio, 0.22; 95% confidence interval, 0.08-0.62). CONCLUSIONS:Equal proportions of children and eAYAs had CCTs available, but significantly fewer eAYAs were enrolled. These findings suggest that, for eAYAs, factors other than CCT availability are important enrollment barriers and should be addressed. Cancer 2018;124:983-90. © 2017 American Cancer Society.

Project description:Acute kidney injury (AKI) has been characterized in high-risk pediatric hospital inpatients, in whom AKI is frequent and associated with increased mortality, morbidity, and length of stay. The incidence of AKI among patients not requiring intensive care is unknown.Retrospective cohort study.13,914 noncritical admissions during 2011 and 2012 at our tertiary referral pediatric hospital were evaluated. Patients younger than 28 days or older than 21 years of age or with chronic kidney disease (CKD) were excluded. Admissions with 2 or more serum creatinine measurements were evaluated.Demographic features, laboratory measurements, medication exposures, and length of stay.AKI defined as increased serum creatinine level in accordance with KDIGO (Kidney Disease: Improving Global Outcomes) criteria. Based on time of admission, time interval requirements were met in 97% of cases, but KDIGO time window criteria were not strictly enforced to allow implementation using clinically obtained data.2 or more creatinine measurements (one baseline before or during admission and a second during admission) in 2,374 of 13,914 (17%) patients allowed for AKI evaluation. A serum creatinine difference ?0.3mg/dL or ?1.5 times baseline was seen in 722 of 2,374 (30%) patients. A minimum of 5% of all noncritical inpatients without CKD in pediatric wards have an episode of AKI during routine hospital admission.Urine output, glomerular filtration rate, and time interval criteria for AKI were not applied secondary to study design and available data. The evaluated cohort was restricted to patients with 2 or more clinically obtained serum creatinine measurements, and baseline creatinine level may have been measured after the AKI episode.AKI occurs in at least 5% of all noncritically ill hospitalized children, adolescents, and young adults without known CKD. Physicians should increase their awareness of AKI and improve surveillance strategies with serum creatinine measurements in this population so that exacerbating factors such as nephrotoxic medication exposures may be modified as indicated.

Project description:BackgroundAdolescents and early young adults (AYAs) with cancer are at high risk for poor outcomes. Positive psychological responses such as benefit-finding may buffer the negative impacts of cancer but are poorly understood in this population.ObjectiveWe aimed to prospectively describe the content and trajectory of benefit- and burden-finding among AYAs to develop potential targets for future intervention.Patients and methodsOne-on-one semistructured interviews were conducted with English-speaking AYA patients (aged 14-25 years) within 60 days of diagnosis of a noncentral nervous system malignancy requiring chemotherapy, 6-12 and 12-18 months later. Interviews were coded using directed content analyses with a priori schema defined by existing theoretical frameworks, including changed sense of self, relationships, philosophy of life, and physical well-being. We compared the content, raw counts, and ratios of benefit-to-burden by patient and by time point.Setting/subjectsSeventeen participants at one tertiary academic medical center (mean age 17.1 years, SD = 2.7) with sarcoma (n = 8), acute leukemia (n = 6), and lymphoma (n = 3) completed 44 interviews with >100 hours of transcript-data.ResultsAverage benefit counts were higher than average burden counts at each time point; 68% of interviews had a benefit-to-burden ratio >1. Positive changed sense-of-self was the most common benefit across all time points (44% of all reported benefits); reports of physical distress were the most common burden (32%). Longitudinal analyses suggested perceptions evolved; participants tended to focus less on physical manifestations and more on personal strengths and life purpose.ConclusionsAYAs with cancer identify more benefits than burdens throughout cancer treatment and demonstrate rapid maturation of perspectives. These findings not only inform communication practices with AYAs but also suggest opportunities for interventions to potentially improve outcomes.

Project description:BACKGROUND:One in three adolescents and young adults with type 1 diabetes have at least one early diabetes-related complication or comorbidity. We aimed to examine the prevalence and pattern of co-occurring complications in this population, as well as the related risk factors. METHODS:This observational cohort study includes data from individuals diagnosed with type 1 diabetes before age 20 years who participated in the SEARCH for Diabetes in Youth Study across five sites in the USA. We assessed sociodemographic and metabolic risk factors at baseline and at follow-up, and diabetes complications at follow-up. A frequency analysis was done to examine the difference in observed versus expected prevalence (calculated using a contingency table assuming independence across cells) of co-occurring complications or comorbidities. A cluster analysis was done to identify unique clusters of participants based on demographic characteristics and metabolic risk factors. FINDINGS:1327 participants who completed the follow-up visit were included in the frequency analysis. The mean age was 10·1 (SD 3·9) years at the time of type 1 diabetes diagnosis and 18·0 (4·1) years at follow-up. At a mean diabetes duration of 7·8 [SD 1·9] years, co-occurrence of any two or more complications was observed in 78 (5·9%) participants, more frequently than expected by chance alone (58 [4·4%], p=0·015). Specifically, the complications that co-occurred more frequently than expected were retinopathy and diabetic kidney disease (11 [0·8%] vs three [0·2%]; p=0·0007), retinopathy and arterial stiffness (13 [1·0%] vs four [0·3%]; p=0·0016), and arterial stiffness and cardiovascular autonomic neuropathy (24 [1·8%] vs 13 [1·0%]; p=0·015). We identified four unique clusters characterised by progressively worsening metabolic risk factor profiles (longer duration of diabetes and higher glycated haemoglobin, non-HDL cholesterol, and waist-to-height ratio). The prevalence of at least two complications increased across the clusters (six [2·3%] of 261 in the low-risk cluster, 32 [6·3%] of 509 in the moderate-risk cluster, 28 [8%] of 348 in the high-risk cluster, and five [20·8%] of 24 in the highest-risk cluster). Compared with the low-risk and moderate-risk clusters, the high-risk and highest-risk clusters were characterised by a lower proportion of participants who were non-Hispanic white, and a higher proportion of participants who had a household income below US$50?000 and did not have private health insurance. INTERPRETATION:Early complications co-occur in adolescents and young adults with type 1 diabetes more frequently than expected. Identification of individuals with adverse risk factors could enable targeted behavioural or medical interventions that reduce the likelihood of early development of lifelong diabetes-related morbidity.
