Longitudinal person-centered measurement: A psychometric evaluation of the Preparedness for Colorectal Cancer Surgery Questionnaire (PCSQ)

OBJECTIVE

The Preparedness for Colorectal Cancer Surgery Questionnaire (PCSQ) was previously developed in Swedish to assess patients' knowledge seeking and sense making capabilities. Aiming to measure preparedness at different phases during the pre-surgery and recovery period, the objectives were to (a) evaluate psychometric properties of the longitudinal PCSQ, (b) establish measurement invariance over time, and (c) describe change in preparedness.

METHODS

Elective colorectal cancer surgery patients completed a questionnaire at five time points from pre-surgery until 6 months post-surgery (n=250). The longitudinal PCSQ consists of 23 items measuring four domains: Searching for and making use of information, Understanding and involvement in care, Making sense of recovery, Support and access to care. Psychometric analyses, including confirmatory factor analysis, were applied to evaluate internal consistency reliability and ascertain invariance over time of the measurement structure and parameters.

RESULTS

The psychometric analyses revealed good fit of the measurement models, high internal consistency reliability (≥.94), and support for configural, metric and scalar measurement invariance of the four PCSQ domains. Patients reported lower levels of preparedness after surgery than pre-surgery.

CONCLUSION

The adapted version of the PCSQ can be used for longitudinal analyses.

PRACTICE IMPLICATIONS

The measurement of preparedness is important for evaluating person-centred outcomes before and during recovery from colorectal cancer surgery.

Thermogenic activity of UCP1 in human white fat-derived beige adipocytes

Heat-producing beige/brite (brown-in-white) adipocytes in white adipose tissue have the potential to suppress metabolic disease in mice and hold great promise for the treatment of obesity and type 2 diabetes in humans. Here, we demonstrate that human adipose-derived stromal/progenitor cells (hASCs) from subcutaneous white adipose tissue can be efficiently converted into beige adipocytes. Upon pharmacological activation of peroxisome proliferator-activated receptor-γ, hASC-derived adipocytes activated beige fat-selective genes and a brown/beige fat-selective electron transport chain gene program. Importantly, hASC-derived beige fat cells displayed the bioenergetic characteristics of genuine brown fat cells, including a capacity for increased respiratory uncoupling in response to β-adrenergic agonists. Furthermore, knock-down experiments reveal that the thermogenic capacity of human beige fat cells was entirely dependent on the presence of Uncoupling protein 1. In summary, this study reveals that hASCs can be readily differentiated into beige adipocytes that, upon activation, undergo uncoupling protein 1-dependent thermogenesis.

Long-term adjustment to living with an ileal pouch-anal anastomosis

PURPOSE

The aim of this study was to describe long-term adjustment to life with an ileal pouch-anal anastomosis after surgery for ulcerative colitis, to investigate the relationship of pouch function to adjustment, and to explore factors affecting quality of life.

METHODS

A total of 369 patients treated between 1982 and 1993 were included in the study. Questionnaires designed to assess bowel (pouch) function (Öresland score) and disease-specific adjustment (Swedish version of the Ostomy Adjustment Scale), plus open-ended questions regarding quality of life, were sent by mail. Open-ended questions were analyzed with qualitative content analysis.

RESULTS

A total of 252 patients (84%) returned the disease-specific adjustment questionnaire (141 males/111 females); median age, 51 (range, 26-77) years; median follow-up, 15 (range, 10-21) years after construction of the ileal pouch-anal anastomosis. High adjustment ratings were found for all statements, with the maximum median score of 6 on 28 of the 36 items. Items with the lowest ratings (median score, 5) pertained to things one would do if not for the IPAA, feeling free to travel, ability to enjoy sexual activities, comfort with body image, ability to laugh about awkward situations, confidence in the appliance, and whether the surgery helped with decisions on what things are most important in life. Participants with the lowest adjustment scores had low bowel function scores (P < .0001). Open-ended quality of life questions were answered by 150 patients (59.5%). The most important areas for quality of life were health, family, restroom access, and friends. Five categories emerged from the qualitative content analysis: living a "normal" life, food restrictions, physical limitations, influence of restroom access on social life, and being dependent on medical care.

CONCLUSIONS

Most participants had adjusted well to life with an ileal pouch-anal anastomosis and considered life to be normal. Good public restrooms were important for quality of life. Improving pouch function may help patients adjust to the postoperative state, but deeper understanding of reasons for poor adjustment despite good pouch function is needed.
