ABSTRACT
Context: Health-related quality of life (HRQOL) assessment plays an important role in the decision-making process in oncology. Aims: The aim of the study was to translate European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ) OES18 and OG25 in Punjabi language for HRQOL assessment of patients diagnosed with esophagus and esophagogastric malignancies. Subjects and Methods: The EORTC translation guidelines were duly followed to translate QLQ-OES18 and OG25 into Punjabi language. Each set of questionnaire was independently translated by two forward translators, followed by backward translation of the reconciled version by two independent translators. The final version was submitted to the EORTC Translation Team and served to the patients for the pilot testing. Results: The questionnaire was administered to ten patients each of esophagus and esophagogastric malignancies who were evaluated and treated at our hospital. Every patient underwent an interview to check if any of the questions was difficult, uncomfortable, or upsetting to answer. Their concerns were recorded as per the template provided by the EORTC team and due changes done if required. Conclusions: The EORTC QLQ-OES18 and OG25 questionnaire has been translated to Punjabi language and subsequently approved for usage.
ABSTRACT
The aim of this study was to validate the translation of the Overactive Bladder (OAB) Screener (OAB V8) to the Malay language. It was to assess the reliability of the screener in the context of a Malaysian population. The original screener consists of eight symptoms indicative of OAB that has been proven to be highly sensitive and reliable. Translation was done with a modification of the Brislin Method using back translation and a panel of experts as a final review panel. The pilot study had two groups; a symptomatic (n=19 patients) and an asymptomatic group (n=18 patients). All patients performed the test twice at two week intervals once at the clinic and subsequently at home. Test-retest method was used for reliability and Cronbach’s alpha for internal consistency. The translated questionnaire demonstrated good internal consistency in both groups of patients for all eight items individually and for the total score. Cronbach’s alphas ranged from 0.972 to 0.981 for the symptomatic group and from 0.750 to 0.976 for the asymptomatic group. Testretest correlation for all items was highly significant. Intraclass correlation (ICC) was high for both the asymptomatic (ICC ranging from 0.600 to 0.953) and the symptomatic group (ranging from 0.944 to 0.989).The Malay OAB V8 showed itself to be suitable for use, reliable in distinguishing symptomatic and asymptomatic patients and a valid instrument.
ABSTRACT
Current selection guideline for CRT uses broad QRS duration (>120 ms) as a marker for ventricular dyssynchrony. However, more recent data supports mechanical marker specifically measured by Tissue Doppler Imaging (TDI) as a better criterion to predict response to CRT. Sixty seven patients with significant left ventricular dysfunction (EF less than 40%) and narrow QRS complex were prospectively enrolled. They underwent Tissue Doppler Imaging (TDI) study to evaluate intraventricular mechanical dyssynchrony. Dyssynchrony index which is defined as standard deviation of time to peak systolic velocity in twelve ventricular segments was measured. A value greater than 32.6 is taken to reflect significant ventricular dyssynchrony. Overall 38 patients (56.7%) demonstrated significant dyssynchrony. There was no significant correlation between QRS duration and the Ts-SD-12 (r = 0.14, p = 0.11). Ventricular mechanical dyssynchrony is common in patients with normal QRS duration. Therefore, QRS duration alone will miss a substantial proportion of suitable patients for CRT and therefore deny them this adjunct therapy. We propose echocardiographic parameters, specifically TDI, to be included in patient selection criteria for CRT.
