Cross-cultural adaptation and validation of the neurogenic bladder symptom score questionnaire for brazilian portuguese

ABSTRACT Objective: To cross-culturally adapt and check for the reliability and validity of the neurogenic bladder symptom score questionnaire to Brazilian Portuguese, in patients with spinal cord injury and multiple sclerosis. Materials and Methods: The questionnaire was culturally adapted according to international guidelines. The Brazilian version was applied in patients diagnosed with neurogenic bladder due to spinal cord injury or multiple sclerosis, twice in a range of 7 to 14 days. Psychometric properties were tested such as content validity, construct validity, internal consistency, and test-retest reliability. Results: Sixty-eight patients participated in the study. Good internal consistency of the Portuguese version was observed, with Cronbach α of 0.81. The test-retest reliability was also high, with an Intraclass Correlation Coefficient of 0.86 [0.76 - 0.92] (p<0.0001). In the construct validity, the Pearson Correlation revealed a moderate correlation between the Portuguese version of the NBSS and the Qualiveen-SF questionnaire (r = 0.66 [0.40-0.82]; p <0.0001). Conclusions: The process of cross-cultural adaptation and validation of the NBSS questionnaire for the Brazilian Portuguese in patients with neurogenic lower urinary tract dysfunction was concluded.

Evaluation of the World Health Organization 2009 classification of dengue severity in autopsied individuals, during the epidemics of 2011 and 2012 in Brazil

Abstract: INTRODUCTION: The dengue classification proposed by the World Health Organization (WHO) in 2009 is considered more sensitive than the classification proposed by the WHO in 1997. However, no study has assessed the ability of the WHO 2009 classification to identify dengue deaths among autopsied individuals suspected of having dengue. In the present study, we evaluated the ability of the WHO 2009 classification to identify dengue deaths among autopsied individuals suspected of having dengue in Northeast Brazil, where the disease is endemic. METHODS: This retrospective study included 121 autopsied individuals suspected of having dengue in Northeast Brazil during the epidemics of 2011 and 2012. All the autopsied individuals included in this study were confirmed to have dengue based on the findings of laboratory examinations. RESULTS: The median age of the autopsied individuals was 34 years (range, 1 month to 93 years), and 54.5% of the individuals were males. According to the WHO 1997 classification, 9.1% (11/121) of the cases were classified as dengue hemorrhagic fever (DHF) and 3.3% (4/121) as dengue shock syndrome. The remaining 87.6% (106/121) of the cases were classified as dengue with complications. According to the 2009 classification, 100% (121/121) of the cases were classified as severe dengue. The absence of plasma leakage (58.5%) and platelet counts <100,000/mm3 (47.2%) were the most frequent reasons for the inability to classify cases as DHF. CONCLUSIONS: The WHO 2009 classification is more sensitive than the WHO 1997 classification for identifying dengue deaths among autopsied individuals suspected of having dengue.
