Abstract Background Lipedema is a chronic disorder of the adipose tissue that affects mainly women, characterised by symmetrical, excessive fatty tissue on the legs and pain. Standard conservative treatment is long-term comprehensive decongestive therapy (CDT) to alleviate lipedema-related pain and to improve psychosocial well-being, mobility and physical activity. Patients may benefit from surgical removal of abnormally propagated adipose tissue by liposuction. The LIPLEG trial evaluates the efficacy and safety of liposuction compared to standard CDT. Methods/design LIPLEG is a randomised controlled multicentre investigator-blinded trial. Women with lipedema (n=405) without previous liposuction will be allocated 2:1 to liposuction or CDT. The primary outcome of the trial is leg pain reduction by ≥2 points on a visual analogue scale ranging 0–10 at 12 months on CDT or post-completion of liposuction. Secondary outcomes include changes in leg pain severity, health-related quality of life, depression tendency, haematoma tendency, prevalence of oedema, modification physical therapy scope, body fat percentage, leg circumference and movement restriction. The primary analysis bases on intention-to-treat. Success proportions are compared using the Mantel-Haenszel test stratified by lipedema stage at a 5% two-sided significance level. If this test is statistically significant, the equality of the response proportions in the separate strata is evaluated by Fisher’s exact test in a hierarchical test strategy. Discussion LIPLEG assesses whether surgical treatment of lipedema is safe and effective to reduce pain and other lipedema-related health issues. The findings of this trial have the potential to change the standard of care in lipedema. Trial registration ClinicalTrials.gov NCT04272827. Registered on February 14, 2020.

IntroductionAvailable data show that approximately 8%–18% of patients with primary hypertension will develop resistant hypertension. In recent years, catheter-based renal denervation (RDN) has emerged as a potential treatment option for resistant hypertension. A number of observational studies and randomised controlled trials among non-Chinese patients have demonstrated its potential safety and efficacy.Methods and analysisThis is a multicentre, randomised, open-label, parallel-group, active controlled trial that will investigate the efficacy and safety of a 5F saline-irrigated radiofrequency ablation (RFA) used for RDN in the treatment of Chinese patients with resistant hypertension. A total of 254 patients who have failed pharmacological therapy will be enrolled. Eligible subjects will be randomised in a 1:1 ratio to undergo RDN using the RFA plus antihypertensive medication or to receive treatment with antihypertensive medication alone. The primary outcome measure is the change in 24 hours average ambulatory systolic blood pressure from baseline to 3 months, comparing the RDN-plus-medication group with the medication-alone group. Important secondary endpoints include the change in office blood pressure from baseline to 6 months after randomisation. Safety endpoints such as changes in renal function will also be evaluated. The full analysis set, according to the intent-to-treat principle, will be established as the primary analysis population.Ethics and disseminationAll participants will provide informed consent; the study protocol has been approved by the Independent Ethics Committee for each site. This study is designed to investigate the efficacy and safety of RDN using a 5F saline microirrigated RFA. Findings will be shared with participating hospitals, policymakers and the academic community to promote the clinical management of resistant hypertension in China.Trial registrationClinicalTrials.gov ID:NCT02900729; pre-results.

IntroductionIncreasing urban populations have led to the growth of informal settlements, with contaminated environments linked to poor human health through a range of interlinked pathways. Here, we describe the design and methods for the Revitalising Informal Settlements and their Environments (RISE) study, a transdisciplinary randomised trial evaluating impacts of an intervention to upgrade urban informal settlements in two Asia-Pacific countries.Methods and analysisRISE is a cluster randomised controlled trial among 12 settlements in Makassar, Indonesia, and 12 in Suva, Fiji. Six settlements in each country have been randomised to receive the intervention at the outset; the remainder will serve as controls and be offered intervention delivery after trial completion. The intervention involves a water-sensitive approach, delivering site-specific, modular, decentralised infrastructure primarily aimed at improving health by decreasing exposure to environmental faecal contamination. Consenting households within each informal settlement site have been enrolled, with longitudinal assessment to involve health and well-being surveys, and human and environmental sampling. Primary outcomes will be evaluated in children under 5 years of age and include prevalence and diversity of gastrointestinal pathogens, abundance and diversity of antimicrobial resistance (AMR) genes in gastrointestinal microorganisms and markers of gastrointestinal inflammation. Diverse secondary outcomes include changes in microbial contamination; abundance and diversity of pathogens and AMR genes in environmental samples; impacts on ecological biodiversity and microclimates; mosquito vector abundance; anthropometric assessments, nutrition markers and systemic inflammation in children; caregiver-reported and self-reported health symptoms and healthcare utilisation; and measures of individual and community psychological, emotional and economic well-being. The study aims to provide proof-of-concept evidence to inform policies on upgrading of informal settlements to improve environments and human health and well-being.EthicsStudy protocols have been approved by ethics boards at Monash University, Fiji National University and Hasanuddin University.Trial registration numberACTRN12618000633280; Pre-results.

ObjectiveTo give a comprehensive efficacy and safety ranking of different therapeutic regimens of ranibizumab for neovascular age-related macular degeneration (nAMD).DesignA systematic review and network meta-analysis.MethodsThe PubMed, Embase, Cochrane Central Register of Controlled Trials, and other clinical trial registries were searched up to 1 October 2019 to identify related randomised controlled trials (RCT) of different regimens of ranibizumab for nAMD. The primary efficacy outcome was the changes of best-corrected visual acuity (BCVA) at 1 year, the primary safety outcome was the incidence of severe ocular adverse events. Secondary outcomes such as changes of central retinal thickness (CRT) were evaluated. We estimated the standardised mean difference (SMD), ORs, 95% CIs, the surface under the cumulative ranking curves and the mean ranks for each outcome using network meta-analyses with random effects by Stata 14.0.ResultsWe identified 26 RCTs involving 10 821 patients with nAMD randomly assigned to 21 different therapeutic regimens of ranibizumab or sham treatment. Ranibizumab 0.5 mg (treat and extend, T&E) is most effective in terms of changes of BCVA (letters, SMD=21.41, 95% CI 19.86 to 22.95) and three or more lines of BCVA improvement (OR=2.83, 95% CI 1.27 to 4.38). However, it could not significantly reduce retreatment times compared with monthly injection (SMD=−0.94, 95% CI −2.26 to 0.39). Ranibizumab 0.5 mg (3+pro re nata)+non-steroidal anti-inflammatory drugs (NSAIDs) is most effective in reducing CRT and port delivery system of ranibizumab (100 mg/mL) could reduce the number of retreatment most significantly. All regimes have no more risk of severe ocular complications (including vitreous haemorrhage, rhegmatogenous retinal detachment, endophthalmitis, retinal tear and retinal pigment epithelium tear) or cardiocerebral vascular complications.ConclusionsRanibizumab 0.5 mg (T&E) is most effective in improving the visual outcome. The administration of topical NSAIDs could achieve additional efficacy in CRT reduction and visual improvement. Both interventions had acceptable risks of adverse events.
