- Age‐related white matter hyperintensities and overactive bladder: a systematic reviewPublication . Pereira E Silva, Ricardo; de Sousa, Diana Aguiar; Lopes, Filipe Abadesso; Silva‐Ramos, Miguel; Verdelho, AnaIntroduction: Age-related white matter hyperintensities (ARWMHs) on brain magnetic resonance imaging have been associated with lower urinary tract symptoms/dysfunction (LUTS/LUTD), namely overactive bladder (OAB) and detrusor overactivity. We aimed to systematically review existing data on the association between ARWMH and LUTS and which clinical tools have been used for this assessment. Materials and methods: We searched PubMed/MEDLINE, Cochrane Library, and clinicaltrials.gov (from 1980 to November 2021) and considered original studies reporting data on ARWMH and LUTS/LUTD in patients of both sexes aged 50 or above. The primary outcome was OAB. We calculated the unadjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) for the outcomes of interest using random-effects models. Results: Fourteen studies were included. LUTS assessment was heterogeneous and mainly based on the use of nonvalidated questionnaires. Urodynamics assessment was reported in five studies. ARWMHs were graded using visual scales in eight studies. Patients with moderate-to-severe ARWMHs were more likely to present with OAB and urgency urinary incontinence (UUI; OR = 1.61; 95% CI: 1.05-2.49, p = 0.03), I2 = 21.3%) when compared to patients with similar age and absent or mild ARWMH. Discussion and conclusions: High-quality data on the association between ARWMH and OAB is scarce. Patients with moderate to severe ARWMH showed higher levels of OAB symptoms, including UUI, when compared to patients with absent or mild ARWMH. The use of standardized tools to assess both ARWMH and OAB in these patients should be encouraged in future research.
- Translation and validation of the Portuguese version of the International Consultation on Incontinence Questionnaire (ICIQ) Bladder DiaryPublication . Pereira E Silva, Ricardo; Lopes, Filipe; Fernandes, Miguel; Polido, Joana; Ponte, Carolina; Esteves, André; Uren, Alan; dos Reis, José PalmaIntroduction and hypothesis: The International Consultation on Incontinence Questionnaire (ICIQ) Bladder Diary (BD) is a standardized and validated diary, developed in the English language, designed to assess lower urinary tract symptoms (LUTS) in men and women. This study reports the translation, cross-cultural adaptation and validation process of this diary to the Portuguese language. Methods: After translation and back-translation of the ICIQ-BD to Portuguese, 140 urologic patients were asked to fill in this 3-day diary as well as the Overactive Bladder questionnaire Short Form (OABqSF) and a questionnaire evaluating the difficulties in filling out the ICIQ-BD. A subset of 60 patients filled out a second diary with/without LUTS treatment in between (30 patients in each group). In addition, content validity, internal consistency, criterion and construct validity were tested. Results: The Portuguese version of the ICIQ-BD showed adequate internal consistency (Cronbach's alpha of 0.78), and patients reported few difficulties in filling out this tool, answering most commonly 1 on a 1-6 scale of difficulty. Excellent test-retest reliability and responsiveness of the diary were observed when comparing the first diary to a second completed 2-6 weeks later. Criterion validity was also confirmed, given the good correlation with the OABqSF (Pearson's 0.386-0.447). Finally, construct validity was established through statistically significant concordance between data obtained in the BD with generally accepted theories. Conclusion: The present version of the ICIQ-BD is the first bladder diary successfully validated in the Portuguese language. It is a suitable and standardized tool for scientific research and diagnostic assessment of LUTS in adult men and women.
