Pelvic organ prolapse is common and is strongly associated with childbirth and increasing age. Women with prolapse are often advised to do pelvic floor muscle exercises, but evidence supporting the benefits of such exercises is scarce. We aimed to establish the effectiveness of one-to-one individualised pelvic floor muscle training for reducing prolapse symptoms. We did a parallel-group, multicentre, randomised controlled trial at 23 centres in the UK, one in New Zealand, and one in Australia, between June 22, 2007, and April 9, 2010. Female outpatients with newly-diagnosed, symptomatic stage I, II, or III prolapse were randomly assigned (1:1), by remote computer allocation with minimsation, to receive an individualised programme of pelvic floor muscle training or a prolapse lifestyle advice leaflet and no muscle training (control group). Outcome assessors, and investigators who were gynaecologists at trial sites, were masked to group allocation; the statistician was masked until after data analysis. Our primary endpoint was participants' self-report of prolapse symptoms at 12 months. Analysis was by intention-to-treat analysis. This trial is registered, number ISRCTN35911035. 447 eligible patients were randomised to the intervention group (n=225) or the control group (n=222). 377 (84%) participants completed follow-up for questionnaires at 6 months and 295 (66%) for questionnaires at 12 months. Women in the intervention group reported fewer prolapse symptoms (ie, a significantly greater reduction in the pelvic organ prolapse symptom score [POP-SS]) at 12 months than those in the control group (mean reduction in POP-SS from baseline 3.77 [SD 5.62] vs 2.09 [5.39]; adjusted difference 1.52, 95% CI 0.46-2.59; p=0.0053). Findings were robust to missing data. Eight adverse events (six vaginal symptoms, one case of back pain, and one case of abdominal pain) and one unexpected serious adverse event, all in women from the intervention group, were regarded as unrelated to the intervention or to participation in the study. One-to-one pelvic floor muscle training for prolapse is effective for improvement of prolapse symptoms. Long-term benefits should be investigated, as should the effects in specific subgroups.

The use of transvaginal mesh and biological graft material in prolapse surgery is controversial and has led to a number of enquiries into their safety and efficacy. Existing trials of these augmentations are individually too small to be conclusive. We aimed to compare the outcomes of prolapse repair involving either synthetic mesh inlays or biological grafts against standard repair in women. We did two pragmatic, parallel-group, multicentre, randomised controlled trials for our study (PROSPECT [PROlapse Surgery: Pragmatic Evaluation and randomised Controlled Trials]) in 35 centres (a mix of secondary and tertiary referral hospitals) in the UK. We recruited women undergoing primary transvaginal anterior or posterior compartment prolapse surgery by 65 gynaecological surgeons in these centres. We randomly assigned participants by a remote web-based randomisation system to one of the two trials: comparing standard (native tissue) repair alone with standard repair augmented with either synthetic mesh (the mesh trial) or biological graft (the graft trial). We assigned women (1:1:1 or 1:1) within three strata: assigned to one of the three treatment options, comparison of standard repair with mesh, and comparison of standard repair with graft. Participants, ward staff, and outcome assessors were masked to randomisation where possible; masking was obviously not possible for the surgeon. Follow-up was for 2 years after the surgery; the primary outcomes, measured at 1 year and 2 years, were participant-reported prolapse symptoms (i.e. the Pelvic Organ Prolapse Symptom Score [POP-SS]) and condition-specific (ie, prolapse-related) quality-of-life scores, analysed in the modified intention-to-treat population. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN60695184. Between Jan 8, 2010, and Aug 30, 2013, we randomly allocated 1352 women to treatment, of whom 1348 were included in the analysis. 865 women were included in the mesh trial (430 to standard repair alone, 435 to mesh augmentation) and 735 were included in the graft trial (367 to standard repair alone, 368 to graft augmentation). Because the analyses were carried out separately for each trial (mesh trial and graft trial) some women in the standard repair arm assigned to all treatment options were included in the standard repair group of both trials. 23 of these women did not receive any surgery (15 in the mesh trial, 13 in the graft trial; five were included in both trials) and were included in the baseline analyses only. Mean POP-SS at 1 year did not differ substantially between comparisons (standard 5·4 [SD 5·5] vs mesh 5·5 [5·1], mean difference 0·00, 95% CI -0·70 to 0·71; p=0·99; standard 5·5 [SD 5·6] vs graft 5·6 [5·6]; mean difference -0·15, -0·93 to 0·63; p=0·71). Mean prolapse-related quality-of-life scores also did not differ between groups at 1 year (standard 2·0 [SD 2·7] vs mesh 2·2 [2·7], mean difference 0·13, 95% CI -0·25 to 0·51; p=0·50; standard 2·2 [SD 2·8] vs graft 2·4 [2·9]; mean difference 0·13, -0·30 to 0·56; p=0·54). Mean POP-SS at 2 years were: standard 4·9 (SD 5·1) versus mesh 5·3 (5·1), mean difference 0·32, 95% CI -0·39 to 1·03; p=0·37; standard 4·9 (SD 5·1) versus graft 5·5 (5·7); mean difference 0·32, -0·48 to 1·12; p=0·43. Prolapse-related quality-of-life scores at 2 years were: standard 1·9 (SD 2·5) versus mesh 2·2 (2·6), mean difference 0·15, 95% CI -0·23 to 0·54; p=0·44; standard 2·0 (2·5) versus graft 2·2 (2·8); mean difference 0·10, -0·33 to 0·52; p=0·66. Serious adverse events such as infection, urinary retention, or dyspareunia or other pain, excluding mesh complications, occurred with similar frequency in the groups over 1 year (mesh trial: 31/430 [7%] with standard repair vs 34/435 [8%] with mesh, risk ratio [RR] 1·08, 95% CI 0·68 to 1·72; p=0·73; graft trial: 23/367 [6%] with standard repair vs 36/368 [10%] with graft, RR 1·57, 0·95 to 2·59; p=0·08). The cumulative number of women with a mesh complication over 2 years in women actually exposed to synthetic mesh was 51 (12%) of 434. Augmentation of a vaginal repair with mesh or graft material did not improve women's outcomes in terms of effectiveness, quality of life, adverse effects, or any other outcome in the short term, but more than one in ten women had a mesh complication. Therefore, follow-up is vital to identify any longer-term potential benefits and serious adverse effects of mesh or graft reinforcement in vaginal prolapse surgery.

Ultrasound-guided foam sclerotherapy and endovenous laser ablation are widely used alternatives to surgery for the treatment of varicose veins, but their comparative effectiveness and safety remain uncertain.

Introduction: Severe sepsis is associated with high levels of morbidity and mortality, placing a high burden on healthcare resources. We aimed to study outcomes in the five years after severe sepsis. Methods: This was a cohort study using data from a prospective audit in 26 adult ICUs in Scotland. Mortality was measured using clinical databases and quality of life using Short Form 36 (SF-36) at 3.5 and 5 years after severe sepsis. Results: A total of 439 patients were recruited with a 58% mortality at 3.5 years and 61% mortality at 5 years. A total of 85 and 67 patients responded at 3.5 and 5 years follow-up, respectively. SF-36 physical component score (PCS) was low compared to population controls at 3.5 years (mean 41.8 (SD 11.8)) and at 5 years (mean 44.8 (SD 12.7)). SF-36 mental component score (MCS) was slightly lower than population controls at 3.5 years (mean 47.7 (SD 14.6)) and at 5 years after severe sepsis (mean 48.8 (SD 12.6)). The majority of patients were satisfied with their current quality of life (QOL) (80%) and all patients would be willing to be treated in an ICU again if they become critically ill despite many having unpleasant memories (19%) and recall (29%) of ICU events. Conclusions: Patients with severe sepsis have a high ongoing mortality after severe sepsis. They also have a significantly lower physical QOL compared to population norms but mental QOL scores were only slightly below population norms up to five years after severe sepsis. All survivors would be willing to be treated in an ICU again if critically ill. Mortality and QOL outcomes were broadly similar to other critically ill cohorts throughout the five years of follow-up.
