Effectiveness of pharmacological agents for the treatment of non-infectious scleritis: a systematic review protocol.

ABSTRACT: BACKGROUND:Non-infectious scleritis is a potentially sight-threatening condition in which the sclera, the white outer layer of the eye, becomes inflamed. Whilst scleritis can be infective, the majority of cases are due to non-infectious causes, often occurring in association with an underlying systemic autoimmune or auto-inflammatory condition. Thorough systemic work-up is crucial to identify disease aetiology and exclude infection; however, a significant proportion of disease remains idiopathic with the underlying cause unknown. Non-infectious scleritis is normally managed with systemic corticosteroid and immunosuppression, yet there is no widely agreed consensus on the most appropriate therapy, and no national or international guidelines exist for treatment of non-infectious scleritis. METHODS:Standard systematic review methodology will be used to identify, select and extract data from comparative studies of pharmacological interventions used to treat patients with non-infectious scleritis. Searches of bibliographic databases (Cochrane Library, MEDLINE, CINAHL and EMBASE) and clinical trial registers will be employed. No restrictions will be placed on language or date of publication. Non-English articles will be translated where necessary. The primary outcome of interest will be disease activity measured by reduction in scleritis grading according to standardised grading systems. Secondary outcomes will include change in best corrected visual acuity, reduction in concurrent dose of systemic corticosteroid, time to treatment failure, adverse events and health-related quality of life. Risk of bias assessment will be conducted appropriate to each study design. Study selection, data extraction and risk of bias assessment will be completed by two reviewers independently. Data will be presented in a table and a narrative synthesis will be undertaken. Meta-analysis will be performed where methodological and clinical homogeneity exists. Subgroup and sensitivity analysis will be undertaken if appropriate. DISCUSSION:Many studies have investigated the effectiveness of pharmacological agents used in the management of non-infectious scleritis. A systematic review is needed to collate and analyse this evidence. Findings of this systematic review will help guide ophthalmologists managing patients with non-infectious scleritis and may form the basis for evidence-based recommendations for future clinical practice and encourage standardisation of treatment protocols.

Project description:IntroductionPostpartum fatigue is a common symptom among new mothers after their pregnancy. It has a considerable negative impact on women's functional and mental status as well as the development of babies. Identifying effective interventions to prevent or reduce postpartum fatigue is meaningful to improve the quality of life and avoid adverse outcomes of this vulnerable population. This systematic review aims to synthesise non-pharmacological evidence and evaluate the effectiveness of interventions for reducing postpartum fatigue among puerperas.Methods and analysisThis review will be conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. We will systematically search the Cochrane Library, PubMed, Embase, Web of Science, PsycINFO, CINAHL and ProQuest databases to identify clinical trials implementing non-pharmacological interventions conducted during 0-78 weeks postpartum for fatigue reduction. An additional search of OpenGrey will be conducted to identify grey literature. The search will be performed on 30 March 2021 without restrictions on time and language. Two independent reviewers will be responsible for study selection, data extraction and study quality assessment. The Cochrane risk-of-bias tool will be adopted to evaluate the risk biases of the included randomised controlled trials, and the Risk of Bias in Non-randomised Studies of Interventions will be applied to evaluate non-randomised controlled trials. Any disagreements will be referred to a third reviewer to reach a consensus. Findings will be qualitatively synthesised, and a meta-analysis will be conducted for the statistical combination if outcome data are sufficient and available.Ethics and disseminationThis systematic review will not involve the collection of primary data and will be based on published data. Therefore, ethics approval is not required. The final findings will be disseminated through peer-reviewed journals and academic conferences.Prospero registration numberCRD42021234869.

Project description:BackgroundNon-infectious uveitis represents a sub-type of intraocular inflammation often associated with disorders of immune dysregulation. If untreated, the intraocular inflammation may progress to severe visual impairment and blindness. Current treatment is heavily reliant on systemic corticosteroid, often at doses associated with severe side effects. There is a need for efficacious corticosteroid-sparing immunomodulatory therapy for these patients. Current immunomodulators include various immunosuppressants and biologics but mammalian target of rapamycin (mTOR) inhibitors (such as sirolimus and everolimus) may also be contenders for this role. The systematic review proposed here will evaluate the evidence for the use of sirolimus and everolimus in the context of non-infectious uveitis.Method/designStandard systematic review methodology will be used to identify, select and extract data from any comparative or non-comparative study of mTOR inhibitors in patients with non-infectious uveitis excluding case reports. Searches of bibliographic databases (MEDLINE, EMBASE, The Cochrane Library and CINAHL) and clinical trials registers will be performed, with no restriction on language or date of publication. Translation of non-English language articles will be undertaken where necessary. The primary outcome of interest will be uveitis activity as measured by vitreous haze. Secondary outcomes will include other pre-specified measures of uveitis activity (such as anterior chamber cells or central macular thickness) best corrected visual acuity, heath-related quality of life, requirement for concurrent treatment and adverse events. Risk of bias assessment will be performed appropriate to each study design. Study selection, data extraction and risk of bias assessment will be undertaken by two reviewers independently. Data will be grouped, tabulated and narratively synthesised. Meta-analysis will be undertaken where appropriate clinical and methodological homogeneity exists. The review will be published according to PRISMA guidance.DiscussionStudies of various designs have investigated the clinical use of mTOR inhibitors for non-infectious uveitis, and a large international randomised controlled trail of sirolimus for non-infectious uveitis is due to report. The findings of this systematic review will help inform ophthalmologists and aid the improvement of treatment protocols for non-infectious uveitis with regard to the use of mTOR inhibitors.Systematic review registrationPROSPERO CRD42017056390.

Project description:IntroductionMany patients experience acute lower back pain that becomes chronic pain. The proportion of patients using complementary and alternative medicine to treat lower back is increasing. Even though several moxibustion clinical trials for lower back pain have been conducted, the effectiveness and safety of moxibustion intervention is controversial. The purpose of this study protocol for a systematic review is to evaluate the effectiveness and safety of moxibustion treatment for non-specific lower back pain patients.Methods and analysisWe will conduct an electronic search of several databases from their inception to May 2017, including Embase, PubMed, Cochrane Central Register of Controlled Trial, Allied and Complementary Medicine Database, Wanfang Database, Chongqing VIP Chinese Science and Technology Periodical Database, China National Knowledge Infrastructure Database, Korean Medical Database, Korean Studies Information Service System, National Discovery for Science Leaders, Oriental Medicine Advanced Searching Integrated System, the Korea Institute of Science and Technology, and KoreaMed. Randomised controlled trials investigating any type of moxibustion treatment will be included. The primary outcome will be pain intensity and functional status/disability due to lower back pain. The secondary outcome will be a global measurement of recovery or improvement, work-related outcomes, radiographic improvement of structure, quality of life, and adverse events (presence or absence). Risk ratio or mean differences with a 95% confidence interval will be used to show the effect of moxibustion therapy when it is possible to conduct a meta-analysis.Ethics and disseminationThis review will be published in a peer-reviewed journal and will be presented at an international academic conference for dissemination. Our results will provide current evidence of the effectiveness and safety of moxibustion treatment in non-specific lower back pain patients, and thus will be beneficial to patients, practitioners, and policymakers.Trial registration numberCRD42016047468 in PROSPERO 2016.
