Treatment of uterine prolapse stage 2 or higher: a randomized multicenter trial comparing sacrospinous fixation with vaginal hysterectomy (SAVE U trial)

Contains fulltext : 97471.pdf (publisher's version ) (Open Access)BACKGROUND: Pelvic organ prolapse is a common health problem, affecting up to 40% of parous women over 50 years old, with significant negative influence on quality of life. Vaginal hysterectomy is currently the leading treatment method for patients with symptomatic uterine prolapse. Several studies have shown that sacrospinous fixation in case of uterine prolapse is a safe and effective alternative to vaginal hysterectomy. However, no large randomized trials with long-term follow-up have been performed to compare efficacy and quality of life between both techniques.The SAVE U trial is designed to compare sacrospinous fixation with vaginal hysterectomy in the treatment of uterine prolapse stage 2 or higher in terms of prolapse recurrence, quality of life, complications, hospital stay, post-operative recovery and sexual functioning. METHODS/DESIGN: The SAVE U trial is a randomized controlled multi-center non-inferiority trial. The study compares sacrospinous fixation with vaginal hysterectomy in women with uterine prolapse stage 2 or higher. The primary outcome measure is recurrence of uterine prolapse defined as: uterine descent stage 2 or more assessed by pelvic organ prolapse quantification examination and prolapse complaints and/or redo surgery at 12 months follow-up. Secondary outcomes are subjective improvement in quality of life measured by generic (Short Form 36 and Euroqol 5D) and disease-specific (Urogenital Distress Inventory, Defecatory Distress Inventory and Incontinence Impact Questionnaire) quality of life instruments, complications following surgery, hospital stay, post-operative recovery and sexual functioning (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire). Analysis will be performed according to the intention to treat principle. Based on comparable recurrence rates of 3% and considering an upper-limit of 7% to be non-inferior (beta 0.2 and one sided alpha 0.025), 104 patients are needed per group. DISCUSSION: The SAVE U trial is a randomized multicenter trial that will provide evidence whether the efficacy of sacrospinous fixation is similar to vaginal hysterectomy in women with uterine prolapse stage 2 or higher.

Low oxygen affects photophysiology and the level of expression of two-carbon metabolism genes in the seagrass <i>Zostera muelleri</i>

© 2017, Springer Science+Business Media B.V. Seagrasses are a diverse group of angiosperms that evolved to live in shallow coastal waters, an environment regularly subjected to changes in oxygen, carbon dioxide and irradiance. Zostera muelleri is the dominant species in south-eastern Australia, and is critical for healthy coastal ecosystems. Despite its ecological importance, little is known about the pathways of carbon fixation in Z. muelleri and their regulation in response to environmental changes. In this study, the response of Z. muelleri exposed to control and very low oxygen conditions was investigated by using (i) oxygen microsensors combined with a custom-made flow chamber to measure changes in photosynthesis and respiration, and (ii) reverse transcription quantitative real-time PCR to measure changes in expression levels of key genes involved in C4 metabolism. We found that very low levels of oxygen (i) altered the photophysiology of Z. muelleri, a characteristic of C3 mechanism of carbon assimilation, and (ii) decreased the expression levels of phosphoenolpyruvate carboxylase and carbonic anhydrase. These molecular-physiological results suggest that regulation of the photophysiology of Z. muelleri might involve a close integration between the C3 and C4, or other CO2 concentrating mechanisms metabolic pathways. Overall, this study highlights that the photophysiological response of Z. muelleri to changing oxygen in water is capable of rapid acclimation and the dynamic modulation of pathways should be considered when assessing seagrass primary production

Rectal obstruction after a vaginal posterior compartment polypropylene mesh fixed to the sacrospinous ligaments

Item does not contain fulltextWe present a case in which a polypropylene mesh was placed over the posterior vaginal wall and was fixed to the sacrospinous ligaments on both sides. Postoperative a rectal obstruction developed which was only resolved after splitting the entire mesh in the midline. It is hypothesised that the obstruction was due to the fixation of the mesh with irresolvable suture material to the sacrospinous ligaments acting as a hinge on which the bowel folded

Surgical management of pelvic organ prolapse and uterine descent in the Netherlands

Contains fulltext : 117705.pdf (publisher's version ) (Closed access)INTRODUCTION AND HYPOTHESIS: To evaluate current practice in the surgical treatment of uterine descent among members of the Dutch Urogynecological Society and to analyze possible trends in the surgical treatment of pelvic organ prolapse in the Netherlands during the last decade. METHODS: A questionnaire, including case scenarios, was sent to the members of the Dutch Urogynecological Society. Using a nationwide registry from the Netherlands, we assessed the number and type of surgical procedures performed for pelvic organ prolapse between 1997 and 2009. RESULTS: The response rate was 73%, with 161 questionnaires completed. Vaginal hysterectomy, sacrospinous hysteropexy, and the Manchester Fothergill procedure were the most frequently performed surgical interventions for uterine descent. In the case of lower stage uterine descent, uterus preservation was preferred, but in the case of higher stage there was wide variation. Two thirds of the respondents stated that in recent years they tended to save the uterus more often. The registered number of hospital admissions for uterine descent increased by 30% between 1997 and 2009 and the number of surgical procedures almost doubled. The number of vaginal hysterectomies performed because of uterine descent increased by only 15% in this period. CONCLUSIONS: In the Netherlands, surgical policy in the case of uterine descent is very variable, with no clear preference for either hysterectomy or uterus preservation. There was a high increase in hospital admissions and pelvic organ prolapse procedures in the last decade. The number of vaginal hysterectomies performed because of uterine descent did not follow this change, which reflects a trend toward preserving the uterus
