- Background and aim: The impact of nocturia (getting up at night to void) on health-related quality-of-life (HRQoL) is often under-estimated. This study investigated the relative burden in terms of HRQoL and utilities of nocturia in a real-world setting. Methods: Patient data were collected from two surveys: a nocturia-specific, cross-sectional survey of physicians and their patients (DSP), and a general UK population health survey (HSFE). Utilities (EQ-5D-5L), productivity (Work Productivity and Activity Index), and the impact of nocturia symptoms (Nocturia Impact Diary and Overactive Bladder Questionnaires) were assessed against the number of voids. A robust linear regression model with propensity score weights was used to control for confounding factors in estimating utilities. Results: Physician-recorded data were available from 8,738 patients across the US, Germany, Spain, France, and the UK; of these, 5,335 (61%) included patient-reported outcomes. In total, 6,302 controls were drawn from the two surveys and compared to 1,104 nocturia patients. Deterioration of HRQoL was associated with increasing number of night-time voids (pamp;lt;0.0001). In particular, significant differences were observed between 0-1 and 2 voids (pamp;lt;0.001). The regression model demonstrated that nocturia (amp;gt;= 2 per night) is associated with a modest but significant deterioration in utility of 0.0134 (pamp;lt;0.05). Limitations: The cause of nocturia is multifactorial and the mostly elderly patients may have several concomitant diseases. The authors tried to adjust for the most common ones, but there may be diseases or unknown relationships not included. Conclusions: Nocturia negatively affected HRQoL and patient utility. A clear effect is seen already at two voids per night. Every effort should, therefore, be made to reduce nocturia below the bother threshold of two voids per night.

- Several horse breeds have been specifically selected for the ability to exhibit alternative patterns of locomotion, or gaits. A premature stop codon in the gene DMRT3 is permissive for gaitedness across breeds. However, this mutation is nearly fixed in both American Standardbred trotters and pacers, which perform a diagonal and lateral gait, respectively, during harness racing. This suggests that modifying alleles must influence the preferred gait at racing speeds in these populations. A genome-wide association analysis for the ability to pace was performed in 542 Standardbred horses (n = 176 pacers, n = 366 trotters) with genotype data imputed to similar to 74,000 single nucleotide polymorphisms (SNPs). Nineteen SNPs on nine chromosomes (ECA1, 2, 6, 9, 17, 19, 23, 25, 31) reached genome-wide significance (p < 1.44 x 10(-6)). Variant discovery in regions of interest was carried out via whole-genome sequencing. A set of 303 variants from 22 chromosomes with putative modifying effects on gait was genotyped in 659 Standardbreds (n = 231 pacers, n = 428 trotters) using a high-throughput assay. Random forest classification analysis resulted in an out-of-box error rate of 0.61%. A conditional inference tree algorithm containing seven SNPs predicted status as a pacer or trotter with 99.1% accuracy and subsequently performed with 99.4% accuracy in an independently sampled population of 166 Standardbreds (n = 83 pacers, n = 83 trotters). This highly accurate algorithm could be used by owners/trainers to identify Standardbred horses with the potential to race as pacers or as trotters, according to the genotype identified, prior to initiating training and would enable fine-tuning of breeding programs with designed matings. Additional work is needed to determine both the algorithm's utility in other gaited breeds and whether any of the predictive SNPs play a physiologically functional role in the tendency to pace or tag true functional alleles.

- Objective To evaluate the impact of nocturia on patients quality of life and healthcare resource utilisation (HRU) compared with overactive bladder (OAB) and benign prostatic hyperplasia (BPH). Methods Data were drawn from a multinational (France, Germany, Spain, UK and US) survey of physician and patient-reported outcomes. The patient groups of interests were those diagnosed with only nocturia, with only OAB, and with only BPH. Health-related quality of life (HRQoL) and productivity measures were derived from the EuroQoL-5D, OAB-q and the Work Productivity and Activity Impairment Questionnaire (WPAI). Measures of HRU included lower urinary tract symptoms (LUTS)-relevant surgeries, hospitalisations, current use of pads and related physician visits. Bivariate and multivariate regression analyses were used to evaluate associations between HRQoL/HRU/Productivity and nocturia status. Multivariate analysis was used to address any potential confounding factors among the groups, ie age, gender, body mass index (BMI), ethnicity and comorbidities. Results A total of 3552 patients were identified including 358 nocturia patients, 1415 OAB patients and 1779 BPH patients. The mean age of the nocturia patients was 61.2 years with a mean BMI of 27.3. About 60.6% were women, 87.2% were Caucasian, and their most common comorbidities included depression, hypertension and diabetes. In terms of impact, nocturia patients were significantly worse off than OAB patients in their HRQoL. There was no significant difference regarding HRU and productivity measurement. Nocturia patients also presented with significantly worse HRQoL and lower productivity compared with BPH patients. Nocturia patients also had more physician visits. Conclusions Nocturia should be emphasised as a standalone LUTS disease with substantial patient impact. Compared with OAB and/or BPH, nocturia patients presented with a significant reduction on patients quality of life, reduced work productivity and increased utilisation of healthcare resources.
