A creative approach to reducing food waste by reusing industrial cake waste can result in the development of a worldwide favorite snack. This study aimed to evaluate the potential of industrial cake wastes-basic mini cake (BMC), filled mini cake (FMC), and traditional mini cake (TMC)-as sustainable alternatives to wheat flour in producing ring-shaped cookies. After initial screening, FMC was upcycled at 10%, 15%, 20%, 30%, and 50% of wheat flour replacement for ring-shaped cookie processing.

Biodegradable starch foam trays offer an eco-friendly substitute for petroleum-based single-use packaging, notably polystyrene foams. However, they lack flexibility, tensile strength, and water-sensitivity, addressable through lignocellulosic reinforcement. This study aimed to develop biodegradable starch foam trays filled with different food-chain side streams for sustainable alternative packaging.

Despite remarkable progress in applied Surface Plasmon Resonance (SPR)-based methods, concise monitoring of kinetic properties for native biomarkers from patient samples is still lacking. Not only are low concentrations of native targets in patient samples, often in the pM range, a limiting and challenging factor, but body fluids as complex matrices furthermore complicate measurements. The here-described method enables the determination of kinetic constants and resulting affinities for native antigens from patients' cerebrospinal fluid (CSF) and sera binding to antibodies.

Background: Adolescent and young adult (AYA) solid organ transplant recipients experience worsening medical outcomes during transition to adult healthcare. Current understanding and definitions of transition success emphasize first initiation of appointment attendance in adult healthcare; however, declines in attendance over time after transfer remain possible, particularly as AYAs are further removed from their pediatric provider and assume greater independence in their care.

Methods: The current study assessed health-care utilization, medical outcomes, and transition success among 49 AYA heart, kidney, or liver recipients recently transferred to adult healthcare.

Background: Pediatric solid organ transplant recipients are susceptible to posttraumatic stress symptoms (PTSS), given the presence of a life-threatening chronic medical condition and potential for complications. However, little is known about what individual characteristics are associated with an increased risk for PTSS among youth who received an organ transplant. The aim of the current study was to evaluate PTSS and its associations with executive functioning (EF) and personality (i.

Objective: To inform efforts to better support caregivers of children with cancer during the transition from treatment to survivorship, this study sought to characterize caregiver mental health-related quality of life (HRQOL) and anxiety, and examine the influence of family psychosocial risk and caregiver problem-solving on these outcomes.

Method: Participants included 124 caregivers (child age M = 10.05 years; SD = 4.

Objective: Adolescents and young adults (AYAs) with solid organ transplants must attain responsibility for healthcare tasks during transition to adult healthcare. However, healthcare systems often initiate transfer based on age and not independence in care. This study examines specific responsibilities distinguishing AYA organ transplant recipients reporting readiness to transfer.

To examine the role of executive functioning (EF) in health self-management and the transition to adult health care among college students. A total of 378 undergraduate students from a public university participated in the study. Participants reported on EF, health self-management skills, and their readiness to transition to adult care.

Objective: To evaluate the factor structure, validity, and reliability of the Caregiver Medication Barriers to Adherence Scale (CMBAS), which assesses caregivers' barriers to facilitating medication adherence in adolescent and young adults (AYAs) with solid organ transplants.

Methods: The sample included 93 caregivers of AYAs ages 12-22 years who received a liver, kidney, or heart transplant. Caregivers completed the CMBAS and surveys to assess its validity, including internalizing symptoms, personality traits (i.

Objective: Much of the extant literature on adherence barriers has focused on modifiable factors (e.g., knowledge, social support); however, less is known about how barriers may be associated with relatively stable constructs, such as personality traits.

Objective: This systematic review examined the literature regarding health literacy among pediatric cancer patients, survivors, and their caregivers. Specific aims were to identify and summarize measures used, levels of and demographic correlates of health literacy, effects of health literacy interventions, and associations between health literacy and health outcomes.

Methods: The search strategy was executed in the following databases: PubMed, EMBASE, PsycINFO, CINAHL, ERIC, and the Cochrane Library.

Purpose: We investigated whether older donor kidneys aged >75 years have acceptable long-term function and if recipients can benefit sufficiently from the transplantation.

Methods: This single-center study retrospectively analyzed patient data from 217 deceased donor kidney transplants performed between 1998 and 2014 as part of the Eurotransplant Senior Program, where the organ donors were ≥65 years old. Depending on donor age, the groups "older donors" (OD; n = 161) and "very old donors" (VOD; n = 56) received transplants from donors aged 65 to 75 years and >75 years, respectively.

Introduction: Better family adjustment following pediatric solid organ transplantation has been associated with a number of beneficial medical and psychosocial outcomes. Yet few studies have examined which pretransplant variables are associated with posttransplant family adjustment. This information can aid in identifying families that may need support going into the transplantation process and those who are at lower risk of worse posttransplant adjustment.

This study examined patient-reported sleep quality in a single-center cross-sectional sample of adolescents with solid organ transplants and evaluated associations between sleep quality, psychosocial functioning (ie, depression/anxiety symptoms), and HRQOL. Health disparities associated with minority race/ethnicity and socioeconomic variables were also examined. Sixty-nine adolescents (M = 16.

Objective: To identify factors associated with nonmuscle invasive bladder cancer (NMIBC) American Urological Association (AUA) guideline compliance in a rural state, to evaluate compliance rates over time, and to assess the impact of patient and provider rurality on delivery of NMIBC care.

Methods: We identified 847 Iowans in Surveillance, Epidemiology, and End Results-Medicare from 1992 to 2009 with high-grade NMIBC who survived 2 years and were not treated with cystectomy or radiation during this period. Compliance with AUA guidelines was assessed over time and compared to patient demographic, tumor, and treatment institution variables.

Objective: To evaluate the feasibility and acceptability of computerized working memory training in pediatric brain tumor survivors (PBTS) with cognitive deficits, as well as computerized working memory training that is enhanced with parental problem-solving skills training (PSST).

Methods: Twenty-seven PBTS (ages 7-16) recruited from a large, tertiary academic medical center were randomly assigned to computerized working memory training (Standard; n = 14) or computerized working memory training plus PSST (Combined; n = 13). PBTS completed a baseline assessment and parents completed acceptability surveys.

Background: The objective of this study was to examine prospectively the associations between family functioning at the end of tumor-directed treatment and the health-related quality of life (HRQL) of pediatric brain tumor survivors (PBTSs) approximately 9 months later.

Procedure: Thirty-five PBTS (age 6-16 years) and their mothers completed measures of family functioning and survivor HRQL within 5 months of completing tumor-directed therapy (baseline) and again approximately 9 months later (follow-up).

Results: Survivor-rated general family functioning at baseline significantly predicted mother proxy- and self-reported survivor HRQL at follow-up when controlling for survivor HRQL at baseline and relevant demographic and treatment-related variables.
