Psychometric Properties of the Turkish version of The Preparedness for Colorectal Cancer Surgery Questionnaire (PCSQ-TR)

© 2021 American Society of PeriAnesthesia NursesPurpose: Preparing a patient cognitively, psychosocially and emotionally for an operation is important for the healing process. The purpose of this study is to investigate the psycholinguistic and psychometric properties of the Turkish version of The Preparedness for Colorectal Cancer Surgery Questionnaire (PCSQ-TR). Design: Methodological study. Methods: The sample consisted of 220 patients. Patients who underwent operation or reoperation for colorectal cancer were included. The language validity, content validity, discriminant validity and construct validity (confirmatory factor analysis) analyses were performed. The item analysis and internal consistency were examined. Findings: Item total score correlations were between 0.38 and 0.85. The Cronbach's alpha was 0.97 for the overall PCSQ-TR and ranged between 0.85 and 0.91 for its domains. Discriminant validity revealed a statistically significant moderate positive correlation between the patients’ mean score for the overall PCSQ-TR and their subjective preparedness for surgery score (r = 0.64, P = .000). In the confirmatory factor analysis, the fit indexes were χ2/df = 2.5; P = .00, RMSEA = 0.08, CFI = 0.92, IFI = 0.92, RMR = 0.18, GFI = 0.79. Conclusions: PCSQ-TR is a valid and reliable scale that can be used to determine colorectal cancer patients’ preparedness for surgery and recovery. PCSQ-TR can be administered in writing or online and can help identify patients who do not feel ready for the surgical recovery process and need advanced nursing care support

The effects of antibiotics and melatonin on hepato-intestinal inflammation and gut microbial dysbiosis induced by a short-term high-fat diet consumption in rats

High-fat diet (HFD) consumption leads to metabolic disorders, gastrointestinal dysfunction and intestinal dysbiosis. Antibiotics also disrupt the composition of intestinal microbiota. The aim of the present study was to investigate the impact of a short-term feeding with HFD on oxidative status, enteric microbiota, intestinal motility and the effects of antibiotics and/or melatonin treatments on diet-induced hepato-intestinal dysfunction and inflammation. Male Sprague-Dawley rats were pair-fed with either standard chow or HFD (45 % fat) and were given tap water or melatonin (4 mg/kg per d) or melatonin plus antibiotics (ABX; neomycin, ampicillin, metronidazole; each 1 g/l) in drinking water for 2 weeks. On the 14th day, colonic motility was measured and the next day intestinal transit was assessed using charcoal propagation. Trunk blood, liver and intestine samples were removed for biochemical and histopathological evaluations, and faeces were collected for microbiota analysis. A 2-week HFD feeding increased blood glucose level and perirenal fat weight, induced low-level hepatic and intestinal inflammation, delayed intestinal transit, led to deterioration of epithelial tight junctions and overgrowth of colonic bacteria. Melatonin intake in HFD-fed rats reduced ileal inflammation, colonic motility and perirenal fat accumulation. ABX abolished increases in fat accumulation and blood glucose, reduced ileal oxidative damage, suppressed HFD-induced overgrowth in colonic bacteria, and reversed HFD-induced delay in intestinal transit; however, hepatic neutrophil accumulation, hepatic injury and dysfunction were further enhanced. In conclusion, the results demonstrate that even a short-term HFD ingestion results in hepato-intestinal inflammatory state and alterations in bacterial populations, which may be worsened with antibiotic intake, but alleviated by melatonin
