dissertationPelvic floor disorders (PFD) affect one in four women in the United States. Elevated intra-abdominal pressure (IAP) during daily activity or strenuous physical activity has been identified as a risk factor in the prevalence of PFD. However, the relationship between IAP and physical activity remains poorly understood. Despite the lack of scientific evidence, clinicians oftentimes prescribe long-term activity restrictions to urogynecologic postoperative patients to minimize IAP, which is thought to lessen the load on the pelvic floor. Since many health benefits are associated with exercise, it is necessary to understand how IAP changes with activity in order to reduce risk to the pelvic floor while allowing women to be physically active. Current methods of measuring IAP include invasive catheters in the vagina, rectum, bladder, or stomach that are tethered to laboratory equipment and have been shown to have poor dynamic response. These characteristics limit the potential for tracking IAP during daily physical activity away from the clinic. The objectives of this research were to determine how intra-abdominal routine that may be adapted for postsurgical patients. Three phases of this work included (1) development of a wireless gel-filled intravaginal pressure sensor to accurately track intra-abdominal pressure, (2) testing the newly developed intravaginal sensor in benchtop and in vivo settings to determine the utility of sensors in real-world deployments, and (3) using the wireless intravaginal pressure sensor to characterize IAP during exercise and, based upon results, create a low intra-abdominal pressure routine that can be used to exercise while minimizing pressure load on the pelvic floor

Rehabilitation for Multiple Sclerosis in Adults (I); Impairment and Impact on Functioning and Quality of Life: An Overview

Multiple sclerosis (MS) is a chronic, central nervous system, disabling disease. International Classification of Functioning and relevant generic and specific outcome measures are reported. Problems perceived by people with MS (PwMS) affect mobility, sight, continence, feeding, or cognitive impairment, depending on whether acute, chronic, or long-term disability was involved. The most common body function and structure impairments leading to disability and reported by health care professionals are fatigue, weakness, decreased fitness, sensory disorders, pain, upper motor neuron syndromes, ataxia and tremor, balance and postural control problems, gait pattern disorders, visual problems, and neurogenic lower urinary tract and bowel dysfunction; sexual, autonomic, neuropsychological, and neuropsychiatric impairment; dysarthrophonia, dysphagia, and respiratory and sleep disorders. The most frequently affected activities and relationships include mobility, domestic life, community and social activities, remunerative employment, interpersonal relationships, self-care, learning and applying knowledge, and economic life. Limitations in activities of daily life because of fatigue, pain, visual problems, incontinence, sexual and cognitive impairment, depressive disorders, sleep disorders, economic pressure, employment status, and lack of information have an impact on quality of life (QoL). Increased caregiving tasks, psychological burden, limitation in activities and participation, and reduced QoL have a profound influence on caregivers. This paper summarizes the perception of problems and needs, the disease's impact on functioning and QoL of PwMS, and the impact on their significant others and caregivers, according to health and social research.Martinez-Assucena, A.; Marnetoft, S.; Roig Rovira, T.; Hernandez-San-Miguel, J.; Bernabeu, M.; Martinell-Gispert-Sauch, M.

Single-incision mini-slings versus standard synthetic mid-urethral slings for surgical treatment of stress urinary incontinence in women:The SIMS RCT

BACKGROUND: Stress urinary incontinence is the most common type of urinary incontinence in premenopausal women. Until recently, synthetic mid-urethral slings (mesh/tape) were the standard surgical treatment, if conservative management failed. Adjustable anchored single-incision mini-slings are newer, use less mesh and may reduce perioperative morbidity, but it is unclear how their success rates and safety compare with those of standard tension-free mid-urethral slings. OBJECTIVE: The objective was to compare tension-free standard mid-urethral slings with adjustable anchored single-incision mini-slings among women with stress urinary incontinence requiring surgical intervention, in terms of patient-reported effectiveness, health-related quality of life, safety and cost-effectiveness. DESIGN: This was a pragmatic non-inferiority randomised controlled trial. Allocation was by remote web-based randomisation (1 : 1 ratio). SETTING: The trial was set in 21 UK hospitals. PARTICIPANTS: Participants were women aged ≥ 18 years with predominant stress urinary incontinence, undergoing a mid-urethral sling procedure. INTERVENTIONS: Single-incision mini-slings, compared with standard mid-urethral slings. MAIN OUTCOME MEASURES: The primary outcome was patient-reported success rates on the Patient Global Impression of Improvement scale at 15 months post randomisation (≈ 1 year post surgery), with success defined as outcomes of 'very much improved' or 'much improved'. The primary economic outcome was incremental cost per quality-adjusted life-year gained. Secondary outcomes were adverse events, impact on other urinary symptoms, quality of life and sexual function. RESULTS: A total of 600 participants were randomised. At 15 months post randomisation, adjustable anchored single-incision mini-slings were non-inferior to tension-free standard mid-urethral slings at the 10% margin for the primary outcome [single-incision mini-sling 79% (212/268) vs. standard mid-urethral sling 76% (189/250), risk difference 4.6, 95% confidence interval -2.7 to 11.8; pnon-inferiority < 0.001]. Similarly, at 3 years' follow-up, patient-reported success rates in the single-incision mini-sling group were non-inferior to those of the standard mid-urethral sling group at the 10% margin [single-incision mini-sling 72% (177/246) vs. standard mid-urethral sling 67% (157/235), risk difference 5.7, 95% confidence interval -1.3 to 12.8; pnon-inferiority < 0.001]. Tape/mesh exposure rates were higher for single-incision mini-sling participants, with 3.3% (9/276) [compared with 1.9% (5/261) in the standard mid-urethral sling group] reporting tape exposure over the 3 years of follow-up. The rate of groin/thigh pain was slightly higher in the single-incision mini-sling group at 15 months [single-incision mini-sling 15% (41/276) vs. standard mid-urethral sling 12% (31/261), risk difference 3.0%, 95% confidence interval -1.1% to 7.1%]; however, by 3 years, the rate of pain was slightly higher among the standard mid-urethral sling participants [single-incision mini-sling 14% (39/276) vs. standard mid-urethral sling 15% (39/261), risk difference -0.8, 95% confidence interval -4.1 to 2.5]. At the 3-year follow-up, quality of life and sexual function outcomes were similar in both groups: for the International Consultation on Incontinence Questionnaire Lower Urinary Tract Symptoms Quality of Life, the mean difference in scores was -1.1 (95% confidence interval -3.1 to 0.8; p = 0.24), and for the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, International Urogynecological Association-Revised, it was 0 (95% confidence interval -0.1, 0.1; p = 0.92). However, more women in the single-incision mini-sling group reported dyspareunia [12% (17/145), compared with 4.8% (7/145) in the standard mid-urethral sling group, risk difference 7.0%, 95% confidence interval 1.9% to 12.1%]. The base-case economics results showed no difference in costs (-£6, 95% confidence interval -£228 to £208) or quality-adjusted life-years (0.005, 95% confidence interval -0.068 to 0.073) between the groups. There is a 56% probability that single-incision mini-slings will be considered cost-effective at the £20,000 willingness-to-pay threshold value for a quality-adjusted life-year. LIMITATIONS: Follow-up data beyond 3 years post randomisation are not available to inform longer-term safety and cost-effectiveness. CONCLUSIONS: Single-incision mini-slings were non-inferior to standard mid-urethral slings in patient-reported success rates at up to 3 years' follow-up. FUTURE WORK: Success rates, adverse events, retreatment rates, symptoms, and quality-of-life scores at 10 years' follow-up will help inform long-term effectiveness.
