- چکیده:
- چکیده انگلیسی: Background: The Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire is the most validated and the most specific tool for measuring the quality of life of patients with constipation. Over 120 million people live in countries whose official language is Persian. There is no reported Persian version of the PAC-QOL questionnaire yet. The aim of this study was to translate and culturally adapt the PAC-QOL questionnaire and to assess its reliability and validity among Persian patients with chronic constipation.Methods: Following the translation and cultural adaptation of the PAC-QOL questionnaire to Persian, 100 patients (mean±SD age=40.51±13.67) with constipation were recruited for validity measurement and 20 patients were re-examined for reliability. Content validity was assessed based on the opinions of an expert committee and the floor/ceiling effect. Construct validity was evaluated according to the hypothesis test. The SF-36 questionnaire was used for concurrent criterion validity, intra-class correlation coefficient for reliability, and Cronbach’s alpha for internal consistency.Results: The content validity of the PAC-QOL questionnaire was proven, and there was no floor/ceiling effect. Construct validity also was confirmed based on the hypothesis test. The overall Cronbach’s alpha of the PAC-QOL questionnaire was 0.92 (range=0.72–0.92), and the overall intra-class correlation coefficient of the questionnaire was 0.88 (range=0.69–0.87). The correlation between the SF-36 and PAC-QOL questionnaires was moderate.Conclusion: The Persian version of the PAC-QOL questionnaire demonstrated good validity and reliability properties in chronic constipation. Accordingly, Persian researchers and clinicians can benefit from this questionnaire in further research and assessment of treatment outcomes.

- چکیده:
- چکیده انگلیسی: Background: Colorectal cancer (CRC) is one of the most prevalent cancers worldwide. Despite recent progress in
diagnosis and treatment, it remains a major health problem and further studies are needed. We here investigated expression
profiles of the FBXO39, ETS-1 and BMI-1 genes in CRCs to validate any possible diagnostic/prognostic significance.
Material and Methods: Thirty six patients with locally advanced CRC admitted to Hazrate-Rasoul Hospital-Tehran
were enrolled. Initially the expression pattern of FBXO39, ETS-1 and BMI-1 genes were determined using RT-PCR
in CRC tumor and adjacent normal tissues then real-time RT-PCR was employed to quantify BMI-1 gene expression.
Results: FBXO39 expression was restricted to tumor tissues. Interestingly, expression of this gene was detected in all
stage-0 tumor samples. There was a significant relation between FBXO39 gene expression and lymph node involvement.
The ETS-1 gene was expressed in 66% of all tumor tissues with p-value=0.03 for increase as compared to the adjacent
normal samples. In addition, there was a significant relation between ETS-1 gene expression and tumor size and lymph
node involvement. RT-PCR demonstrated BMI-1 gene expression in both tumor and normal tissues and quantification
by real-time RT-PCR showed no association between BMI-1 levels and CRC clinicopathological features. Conclusion:
Expression of FBXO39 and ETS-1 with lymph node involvement may be considered as an alarm for the occurrence
of CRC metastasis, and therfore have prognostic value while BMI-1 appears without importance.- انتشار مقاله: 13-10-1396
