- IntroductionProvoked vestibulodynia (PVD) is a common type of dyspareunia among young women. The patho-physiology remains largely unclear. Women with PVD have general pain hypersensitivity and often report additional pain symptoms. Signs point towards PVD being a chronic pain disorder similar to other syndromes of longstanding pain, including a common comorbidity of anxiety and depression. Polymorphism in the serotonin receptor gene, 5HT-2A, has been associated with other chronic pain disorders such as fibromyalgia but has not been investigated in PVD patients. AimWe aimed to investigate a possible contribution of polymorphism in the 5HT-2A gene to the etiology of PVD as well as a potential influence on pain sensitivity. MethodsIn this case-control study 98 women with PVD and 103 healthy controls between 18 and 44 years and in the same menstrual cycle phase completed questionnaires and underwent quantitative sensory testing. Venous blood samples were collected for DNA isolation. Main Outcome MeasuresConcomitant pain was reported, a bodily pain score was created and pressure pain thresholds (PPTs) on the arm, leg, and in the vestibule were measured. Intensity of coital pain was rated on a visual analog scale, range 0-100. The T102C (rs6313) and A-1438G (rs6311) single nucleotide polymorphisms (SNPs) in the 5HT-2A gene were analyzed. ResultsThe probability of PVD was elevated in participants carrying the 1438G- and 102C-alleles of the 5HT-2A gene (OR 2.9). The G-/C- genotypes were also associated with more concomitant bodily pain in addition to the dyspareunia, but not with experimental PPTs or coital pain ratings. PVD patients reported more concomitant bodily pain and had lower PPTs compared with controls. ConclusionThe results indicate a contribution of alterations in the serotonergic system to the patho-genesis of PVD and gives further evidence of PVD being a general pain disorder similar to other chronic pain disorders.

- Body mass index (BMI) is a modifiable lifestyle factor that has been associated with an increased risk of fatal prostate cancer and biochemical recurrence. The main purpose of the present study was to investigate the association between the exposure BMI at the time of a prostate cancer diagnosis and weight change after diagnosis, and the outcomes of prostate cancer progression and mortality in a large cohort study. Data from 4,376 men diagnosed with clinically localized prostate cancer between 1997 and 2002 were analyzed. BMI and weight change were self-reported in 2007. Hazard ratios (HRs) with 95 % confidence intervals (CIs) were estimated in complete-case analysis (n = 3,214) using Cox proportional hazards models. Progression was experienced among 639 (14.6 %) of the study participants, and in total, 450 (10.3 %) deaths of any cause and 134 (3.1 %) prostate cancer-specific deaths were recorded during follow-up. Obese men had a 47 % increased rate of overall mortality compared to normal weight men (HR 1.47, 95 % CI 1.03-2.10). No statistically significant associations were found for BMI and prostate cancer progression or prostate cancer-specific mortality. A weight loss > 5 % after diagnosis almost doubled the rate of overall mortality compared to maintaining a stable weight (HR 1.94, 95 % CI 1.41-2.66), while a weight gain > 5 % was associated with an almost doubled increased rate of prostate cancer-specific mortality (HR 1.93, 95 % CI 1.18-3.16). Being obese was associated with an increased rate of overall mortality, and gaining weight after a prostate cancer diagnosis was associated with an increased rate of prostate cancer-specific mortality.

- Objective: This study aimed to evaluate the association between perceived stress, social support, disease progression and mortality in a nationwide population-based cohort of men with prostate cancer. Materials and methods: The study surveyed 4105 Swedish men treated for clinically localized prostate cancer regarding stress, grief, sleep habits and social support. Associations between these factors and mortality were assessed using multivariate Cox regression analysis. Results: Men with the highest levels of perceived stress had a statistically significantly increased rate of prostate cancer-specific mortality compared with men with low stress levels (hazard ratio 1.66, 95% confidence interval 1.05-2.63). Men with high stress levels also had a high frequency of grieving and sleep loss. They also had fewer people with whom to share their emotional problems and felt an inability to share most of their problems with partners, friends and family. Conclusions: This study contributes to the growing field of psychosocial quality of life research in men with prostate cancer. The findings show a significant association between prostate cancer-specific mortality and perceived stress in patients initially diagnosed with localized, non-metastatic prostate cancer. Significant associations between perceived stress and various psychosocial factors were also seen. The findings of this study could prove useful to target interventions to improve quality of life in men with prostate cancer.

- BACKGROUND: Deletion polymorphism of the UDP-glucuronosyltransferase 2B17 (UGT2B17) gene has been associated with an increased prostate cancer risk in two previous independent studies. Here we determine the risk in a large-scale population-based case-control study.METHODS: Genotyping was conducted with a 5'-nuclease activity assay to distinguish those with one or two UGT2B17 gene copies (ins/del and ins/ins) from individuals homozygous for the deletion (del/del) allele.RESULTS: In contrast to previous findings, no association between the UGT2B17 deletion polymorphism and prostate cancer risk was found. Furthermore the UGT2B17 gene deletion did not affect the risk for prostate cancer specific death.CONCLUSION: The UGT2B17 deletion polymorphism does not play a major role in prostate cancer susceptibility as previously indicated.

- OBJECTIVE: Being physically active postdiagnosis has been associated with lower rates of prostate cancer progression and mortality, but studies investigating postdiagnostic time spent sitting are lacking. We aim to study the association between leisure time sitting after a prostate cancer diagnosis and overall and prostate cancer-specific mortality. METHODS: Data from 4595 men in Sweden, diagnosed with localized prostate cancer between 1997-2002 and followed-up until the end of 2012, were analyzed. Time spent sitting during leisure time postdiagnosis was categorized into <2, 2-3, 3-4, and >4 h/day. Multivariable-adjusted Cox proportional hazards models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CI) of postdiagnosis leisure time sitting and a joint variable of sitting time and exercise, and time to overall or prostate cancer-specific death. RESULTS: The results showed no significant associations between postdiagnostic leisure time sitting and overall or prostate cancer-specific mortality rates. When the joint effect of both sitting and exercise time was considered, borderline significantly lower mortality rates for overall and prostate cancer-specific mortality were seen among participants that sat the least and exercised the most compared to the reference category with participants sitting the most and exercising least (HR: 0.75; 95% CI: 0.56-1.00 and HR: 0.61; 95% CI: 0.36-1.05, respectively). CONCLUSIONS: No significant association between leisure time sitting and mortality rates among men diagnosed with localized prostate cancer was seen. This study does not support an association between leisure time sitting per se; however, being physically active may have beneficial effects on survival among men diagnosed with localized prostate cancer.

- Bladder monitoring, including urinary incontinence management and bladder urinary volume monitoring, is a vital part of urological care. Urinary incontinence is a common medical condition affecting the quality of life of more than 420 million people worldwide, and bladder urinary volume is an important indicator to evaluate the function and health of the bladder. Previous studies on non-invasive techniques for urinary incontinence management technology, bladder activity and bladder urine volume monitoring have been conducted. This scoping review outlines the prevalence of bladder monitoring with a focus on recent developments in smart incontinence care wearable devices and the latest technologies for non-invasive bladder urine volume monitoring using ultrasound, optical and electrical bioimpedance techniques. The results found are promising and their application will improve the well-being of the population suffering from neurogenic dysfunction of the bladder and the management of urinary incontinence. The latest research advances in bladder urinary volume monitoring and urinary incontinence management have significantly improved existing market products and solutions and will enable the development of more effective future solutions. © 2023 by the authors.
