- OBJECTIVES: To develop and validate a short patient self-assessment screening questionnaire: bladder control self-assessment questionnaire (B-SAQ) for the evaluation of lower urinary tract symptoms. This first validation study was undertaken amongst women. PATIENTS AND METHODS: Three hundred twenty-nine women attending general gynaecology and urogynaecology clinics completed both the B-SAQ and Kings Health questionnaire prior to medical consultation, and independent physician assessment of the presence of lower urinary tract symptoms (LUTS) and need for treatment. The psychometric properties of the B-SAQ were subsequently analysed. RESULTS: The B-SAQ was quick and easy to complete, with 89% of respondents completing all items correctly in less than 5min. The internal consistency (Cronbach's alpha score 0.90-0.91), criterion validity (Pearson's correlation values of 0.79 and 0.81, p<0.0001 with the incontinence impact domain of the Kings Health questionnaire), and test-retest reliability of the questionnaire were good. The sensitivity and specificity of the questionnaire to identify patients with bothersome LUTS was 98% and 79%, respectively. CONCLUSIONS: LUTS are commonly underreported. Empowering patients to self-assess their bladder symptoms and the need for treatment will improve treatment-seeking behaviour. The B-SAQ is a psychometrically robust, short screening questionnaire that offers patients the ability to assess their bladder symptoms and the bother they cause, and the potential benefit of seeking medical help.

- Introduction. The prevalence of sexual dysfunction, including erectile dysfunction (ED), is greater in men with lower urinary tract symptoms (LUTS), including overactive bladder (OAB), than in men without LUTS. Aim. To evaluate the prevalence of ED, the impact of urinary symptoms on sexual activity and sexual enjoyment, and sexual satisfaction in men with OAB. Methods. A nested case-control analysis was performed on data from a subset of men with (cases) and without (controls) OAB frequency-matched for age (5-year age strata) and country from the EPIC study. Respondents were asked about OAB symptoms (using the 2002 International Continence Society [ICS] definitions) and sexual activity. Sexually active respondents were asked about ED, sexual enjoyment, and overall satisfaction with their sex lives. Conditional logistic regression was used to assess factors associated with ED. Main Outcome Measures. The percentage of cases and controls reporting ED, a reduction in the frequency of sexual activity or enjoyment of sexual activity because of urinary symptoms, and overall satisfaction with their sex lives was determined for cases and controls. Results. A total of 502 cases and 502 controls were matched for age strata and country. Significantly more cases (14%) reported reduced sexual activity because of urinary symptoms compared with controls (4%; P

- OBJECTIVE: Estimate the prevalence of urinary incontinence (UI), overactive bladder (OAB), and other lower urinary tract symptoms (LUTS) among men and women in five countries using the 2002 International Continence Society (ICS) definitions. METHODS: This population-based, cross-sectional survey was conducted between April and December 2005 in Canada, Germany, Italy, Sweden, and the United Kingdom using computer-assisted telephone interviews. A random sample of men and women aged >/= 18 yr residing in the five countries and who were representative of the general populations in these countries was selected. Using 2002 ICS definitions, the prevalence estimates of storage, voiding, and postmicturition LUTS were calculated. Data were stratified by country, age cohort, and gender. RESULTS: A total of 19,165 individuals agreed to participate; 64.3% reported at least one LUTS. Nocturia was the most prevalent LUTS (men, 48.6%; women, 54.5%). The prevalence of storage LUTS (men, 51.3%; women, 59.2%) was greater than that for voiding (men, 25.7%; women, 19.5%) and postmicturition (men, 16.9%; women, 14.2%) symptoms combined. The overall prevalence of OAB was 11.8%; rates were similar in men and women and increased with age. OAB was more prevalent than all types of UI combined (9.4%). CONCLUSIONS: The EPIC study is the largest population-based survey to assess prevalence rates of OAB, UI, and other LUTS in five countries. To date, this is the first study to evaluate these symptoms simultaneously using the 2002 ICS definitions. The results indicate that these symptoms are highly prevalent in the countries surveyed.

The economic impact of overactive bladder syndrome in six Western countries

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To calculate up-to-date estimates of the economic impact of overactive bladder syndrome (OAB) with and without urgency urinary incontinence (UUI) on the health sector of six countries (Canada, Germany, Italy, Spain, Sweden and the UK), as OAB is a significant health concern for adults aged >18 years living in Western countries. MATERIALS AND METHODS: The prevalence data derived from the EPIC study were combined with healthcare resource-use data to derive current direct and indirect 1-year or annual cost of illness estimates for OAB including UUI in Canada, Germany, Italy, Spain, Sweden and the UK. This model estimates the direct healthcare costs attributed to OAB, as well as the impact of work absenteeism. RESULTS: The estimated average annual direct cost of OAB per patient ranged between 262 in Spain and 619 in Sweden. The estimated total direct cost burden for OAB per country ranges between 333 million in Sweden and 1.2 billion in Germany and the total annual direct cost burden of OAB in these six countries is estimated at 3.9 billion. In addition, nursing home costs were estimated at 4.7 billion per year and it was estimated that work absenteeism related to OAB costs 1.1 billion per year. CONCLUSIONS: The cost of illness for OAB is a substantial economic and human burden. This study may under-estimate the true economic burden, as not all costs for sequelae associated with OAB have been included. Cost-effective treatments and management strategies that can reduce the burden of OAB and in particular UUI have the potential to significantly reduce this economic burden.

Mapping the interaction of the STT3 subunit of the oligosaccharyl transferase complex with nascent polypeptide chains

- Many secretory and membrane proteins are N-glycosylated by the oligosaccharyl transferase complex during their translocation across the endoplasmic reticulum membrane. Several experimental observations suggest that the highly conserved STT3 subunit contains the active site of the oligosaccharyl transferase. Here, we report a detailed study of the interaction between the active site of the STT3 protein and nascent polypeptide chains using an in vitro photocrosslinking technique. Our results show that the addition of a glycan moiety in a stretch of similar to 15 residues surrounding a QK*T cross-linking site impairs the interaction between the nascent chain and STT3.

The genome of black cottonwood, Populus trichocarpa (Torr. & Gray).

- We report the draft genome of the black cottonwood tree, Populus trichocarpa. Integration of shotgun sequence assembly with genetic mapping enabled chromosome-scale reconstruction of the genome. More than 45,000 putative protein-coding genes were identified. Analysis of the assembled genome revealed a whole-genome duplication event; about 8000 pairs of duplicated genes from that event survived in the Populus genome. A second, older duplication event is indistinguishably coincident with the divergence of the Populus and Arabidopsis lineages. Nucleotide substitution, tandem gene duplication, and gross chromosomal rearrangement appear to proceed substantially more slowly in Populus than in Arabidopsis. Populus has more protein-coding genes than Arabidopsis, ranging on average from 1.4 to 1.6 putative Populus homologs for each Arabidopsis gene. However, the relative frequency of protein domains in the two genomes is similar. Overrepresented exceptions in Populus include genes associated with lignocellulosic wall biosynthesis, meristem development, disease resistance, and metabolite transport.
