Advancing textural heterogeneity: Effect of manipulating multi-component model foods on the perception of textural complexity.

The aim of this study was to identify the individual and interacting effects of varying the mechanical properties of two inserts (к-carrageenan beads; 1, 2 and 4% w/w and/or agar-based disks; 0.3, 1.2 and 3% w/w) in pectin-based gels on the perception of textural complexity. A full factorial design was utilised, 16 samples were characterised with sensory and instrumental tests. Rate-All-That-Apply (RATA) was performed by 50 untrained participants. RATA selection frequency provided different information to attribute intensity regarding the detection of low yield stress inserts. In the two-component samples, the perception of textural complexity (n = 89) increased with insert yield stress for both к-carrageenan beads and agar disks. However, with the addition of medium and high yield stress к-carrageenan beads to three-component samples, the increases in perceived textural complexity caused by increased agar yield stress were eliminated. The definition of textural complexity, the number and intensity of texture sensations, as well as their interactions and contrasts, was in line with the results, and the hypothesis that not only mechanical properties but also the interaction of components play a key role in the perception of textural complexity.

A Systematic Review of Patient and Caregiver Experiences with a Tracheostomy.

BACKGROUND: A tracheostomy is a surgically created opening through the anterior neck tissues and the trachea, into which a tube is inserted. Despite its influence on basic human needs such as respiration, communication and nutrition, little is known about the impact of tracheostomy on patients and their caregivers or what could be done to enable better care and quality of life (QoL) for these individuals. OBJECTIVE: The aim of this review was to better understand the current knowledge related to the experience and QoL of adults living with a tracheostomy and their caregivers so as to be able to improve these experiences. METHOD: A systematic review of the English-language, peer-reviewed literature was conducted in PubMed, Scopus, PsychINFO, Google Scholar, and CINAHL databases. Articles were eligible if they included adult patient or lay caregiver-reported experiences of tracheostomy. RESULTS: Overall, 1080 articles were identified and 17 eligible for inclusion. Fourteen articles reported on experiences of tracheostomy patients, while three focused on those of their caregivers. Studies were conducted in the home setting (n = 5), on a hospital ward (n = 4), in an intensive care unit (n = 3), in an outpatient clinic (n = 3), in a rehab facility (n = 1), and online (n = 1). Patients and their caregivers reported a range of mostly negative experiences related to the care, support, and management of a tracheostomy, speech and communication, wellbeing and QoL, disfigurement and body image, and stigma and social withdrawal. CONCLUSION: Few studies have published data on the patient and caregiver experiences with tracheostomy, especially in the community setting. There is a need to better understand these experiences in order to be able to formulate strategies and provide resources to improve the quality of care and overall QoL of patients with a tracheostomy and their caregivers in-hospital and in the community.
