ABSTRACT

AIMS: To evaluate effectiveness of transcutaneous tibial nerve stimulation (TTNS) for treating adults with overactive bladder (OAB) of idiopathic or neurogenic origin, using a systematic review of the literature. METHODS: Systematic searches of four databases were undertaken between 1980 and 2017. Included studies investigated effects of TTNS on OAB. Study selection, data extraction, quality appraisal was performed by two independent reviewers. Narrative analysis was undertaken where meta-analysis was not possible due to study heterogeneity. Meta-analysis of RCTs was performed using a fixed effects model. RESULTS: Ten RCTs and three prospective cohort studies involving 629 participants were reviewed. Meta-analysis of two trials comparing TTNS with sham showed mean reduction in total ICIQ Urinary Incontinence Short Form (ICIQ-UI SF) associated with TTNS of -3.79 (95% CI -5.82, -1.76; P = 0.0003, I2 = 25%). Narrative review showed TTNS and antimuscarinic treatment were equally effective (four trials), TTNS provided greater benefit for OAB symptoms than behavioral interventions (two trials), tibial nerve, and sacral foramen stimulation were equally effective but combined stimulation was most effective (one trial). Significant improvements in OAB symptoms were reported by 48-93% participants and UI cure rates of 25-45%. No adverse events were reported. CONCLUSIONS: Limited evidence is provided that TTNS is an effective, safe intervention for idiopathic OAB in adults and may be of benefit in those with neurogenic OAB. Further studies are essential to confirm these results as well as to determine efficacy and associated costs for specific patient groups, most effective stimulation dosage, duration of effect, and stimulation regimes for longer-term maintenance.

ABSTRACT

BACKGROUND: Several studies suggest that perceived psychosocial stress is associated with increased risk of stroke; however results are inconsistent with regard to definitions and measurement of perceived stress, features of individual study design, study conduct and conclusions drawn and no meta-analysis has yet been published. We performed a systematic review and meta-analysis of studies assessing association between perceived psychosocial stress and risk of stroke in adults.The results of the meta-analysis are presented. METHODS: Systematic searches of MEDLINE, EMBASE, CINAHL, PsycInfo, and Cochrane Database of Systematic Reviews were undertaken between 1980 and June 2014. Data extraction and quality appraisal was performed by two independent reviewers. Hazard ratios (HR) and odds ratios (OR) were pooled where appropriate. RESULTS: 14 studies were included in the meta-analysis, 10 prospective cohort, 4 case-control design. Overall pooled adjusted effect estimate for risk of total stroke in subjects exposed to general or work stress or to stressful life events was 1.33 (95 % confidence interval [CI], 1.17, 1.50; P < 0.00001). Sub-group analyses showed perceived psychosocial stress to be associated with increased risk of fatal stroke (HR 1.45 95 % CI, 1.19,1.78; P = 0.0002), total ischaemic stroke (HR 1.40 95 % CI, 1.00,1.97; P = 0.05) and total haemorrhagic stroke (HR 1.73 95 % CI, 1.33,2.25; P > 0.0001).A sex difference was noted with higher stroke risk identified for women (HR 1.90 95 % CI, 1.4, 2.56: P < 0.0001) compared to men (HR 1.24 95 % CI, 1.12, 1.36; P < 0.0001). CONCLUSIONS: Current evidence indicates that perceived psychosocial stress is independently associated with increased risk of stroke.
