Occupational noise-induced hearing loss (ONIHL) is one of the most recognised occupational diseases globally. Mining and earthworks are among those with the greatest impact in this matter. A systematic review addressing the noise exposure characterisation, in order to develop a preventive design, is being proposed in this protocol. The Preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) guidelines were used to draw the research outline, where the study and report characteristics are provided. All of the selected keywords and databases/journals were priorly identified and are now presented. The search methodology is clarified, and an example for Scopus is provided. A methodology to deal with bias within studies is proposed, and all the systematic review narrative processes of the systematic review are discussed in the protocol, including information that will be extracted from the selected records. The Preferred Reporting Items for Systematic Review and Meta-analysis guidelines will be used to help develop the review.

ObjectiveMost of the Chinese occupational population are becoming at risk of noise-induced hearing loss (NIHL). However, there is a limited number of literature reviews on occupational NIHL in China. This study aimed to analyse the prevalence and characteristics of occupational NIHL in the Chinese population using data from relevant studies.DesignSystematic review and meta-analysis.MethodsFrom December 2019 to February 2020, we searched the literature through databases, including Web of Science, PubMed, MEDLINE, Scopus, the China National Knowledge Internet, Chinese Sci-Tech Journal Database (weip.com), WanFang Database and China United Library Database, for studies on NIHL in China published in 1993–2019 and analysed the correlation between NIHL and occupational exposure to noise, including exposure to complex noise and coexposure to noise and chemicals.ResultsA total of 71 865 workers aged 33.5±8.7 years were occupationally exposed to 98.6±7.2 dB(A) (A-weighted decibels) noise for a duration of 9.9±8.4 years in the transportation, mining and typical manufacturing industries. The prevalence of occupational NIHL in China was 21.3%, of which 30.2% was related to high-frequency NIHL (HFNIHL), 9.0% to speech-frequency NIHL and 5.8% to noise-induced deafness. Among manufacturing workers, complex noise contributed to greater HFNIHL than Gaussian noise (overall weighted OR (OR)=1.95). Coexposure to noise and chemicals such as organic solvents, welding fumes, carbon monoxide and hydrogen sulfide led to greater HFNIHL than noise exposure alone (overall weighted OR=2.36). Male workers were more likely to experience HFNIHL than female workers (overall weighted OR=2.26). Age, noise level and exposure duration were also risk factors for HFNIHL (overall weighted OR=1.35, 5.63 and 1.75, respectively).ConclusionsThe high prevalence of occupational NIHL in China was related to the wide distribution of noise in different industries as well as high-level and long-term noise exposure. The prevalence was further aggravated by exposure to complex noise or coexposure to noise and specific chemicals. Additional efforts are needed to reduce occupational noise exposure in China.

Review Protocol

A number of epidemiological studies report an association between occupational noise exposure and arterial hypertension. Existing systematic reviews report conflicting results, so we conducted an updated systematic review with meta-analysis. We registered the review protocol with PROSPERO (registration no.: CRD 42019147923) and searched for observational epidemiological studies in literature databases (Medline, Embase, Scopus, Web of Science). Two independent reviewers screened the titles/abstracts and full texts of the studies. Two reviewers also did the quality assessment and data extraction. Studies without adequate information on recruitment, response, or without a comparison group that was exposed to occupational noise under 80 dB(A) were excluded. The literature search yielded 4583 studies, and 58 studies were found through hand searching. Twenty-four studies were included in the review. The meta-analysis found a pooled effect size (ES) for hypertension (systolic/diastolic blood pressure ≥140/90 mmHg) due to noise exposures ≥80 dB(A) of 1.81 (95% CI 1.51–2.18). There is no substantial risk difference between men and women, but data concerning this question are limited. We found a positive dose-response-relationship: ES = 1.21 (95% CI 0.78–1.87) ≤ 80 dB(A), ES = 1.77 (95% CI 1.36–2.29) > 80–≤85 dB(A), and ES = 3.50 (95% CI 1.56–7.86) > 85–≤90 dB(A). We found high quality of evidence that occupational noise exposure increases the risk of hypertension.

Review Protocol

Abstract Introduction: Motor function is essential in our daily lives, one of the most common impairments caused by stroke is loss of functional movement. Over 70% of stroke survivors have motor or other neurological functional disabilities. However, rehabilitation of motor function suffered from a stroke can be rather difficult due to the complexity of organs and systems related to motor function, as well as the neural system that supported motor function. In particularly, previous evidence for the effectiveness of physiotherapy, a commonly prescribed intervention method for people with stroke, that recover motor function in people following a stroke is varied and limited in the chronic rehabilitation phase and therefore has never been reviewed systematically. With the progress of study in neurology and the development of novel tools for rehabilitation, results from more and more clinical trials are now available, thus here justifying conducting a systematic review. Methods and analysis: This systematic review protocol is developed in accordance with the methodology recommended by the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols, as well as the Cochrane handbook for systematic reviews of interventions. Relevant studies will be identified by searching the databases. We will perform searches for relevant studies in databases, including PubMed, Embase, CINAHL, and Web of Science, Physiotherapy Evidence Database and Cochrane Library databases. The reference lists of included articles and reviews will be searched manually. The date range parameters used in searching all databases will be restricted between January 2001 and January 2021. Randomized controlled trials (RCTs) published will be included. The language used in the articles included was restricted to English. The GRADE (Grading of Recommendations, Assessment, Development and Evaluation system from the Cochrane Handbook for Systematic Reviews of Interventions) approach will be used to systematically appraise the quality of methodology. We will assess the risk of bias of the RCTs included using the Cochrane Collaboration’s tool and provide a qualitative synthesis. After that, we will consider conducting a meta-analysis if the final data across outcomes shows sufficient homogeneity. Ethics and dissemination: No ethical approval is needed as the proposed study does not involve the collection of primary data, and the results of this review will be disseminated via peer-reviewed publications and conference presentations. Trial registration number: CRD42021267069.

Exposure Levels

Current legislation and threshold limits for occupational noise exposure may not sufficiently account for higher vulnerability of the foetus. We conducted a systematic literature review and identified 20 relevant studies of prenatal noise exposure levels and health. Maternal tissues attenuate industrial noise by about 30 dB. The foetus responds the earliest to noise exposure from the 19th week of gestational age. There is some evidence of an increased risk of hearing loss at prenatal noise levels≥85 dBA (8 hour average) and little evidence at lower levels. Increased risks for preterm birth, small-for-gestational-age and congenital malformations are seen as single study findings at levels≥90 dBA. There is little evidence for how noise exposure may increase the risk of extra-auditive effects in the foetus. Methodological shortcomings and the scarce number of studies limit the conclusions that can be drawn. Still, we recommend pregnant women avoid working at noise levels≥85 dBA.

IntroductionOne-quarter of the global population, including the majority of adults in tuberculosis (TB) endemic countries, are estimated to beMycobacterium tuberculosis(MTB) infected. An estimated 10 million new TB cases occurred in 2017. One of the biggest challenges confronting TB control is the lack of accurate diagnosis and prediction of prevalent and incident TB disease, respectively. Several host blood transcriptomic messenger RNA (mRNA) signatures that reflect the host immune response following infection with MTB and progression to TB disease in different study populations have recently been published, but these TB biomarkers have not been systematically described. We will conduct a systematic review of the performance of host blood transcriptional signatures for TB diagnosis and prediction of progression to TB disease.Methods and analysisThis systematic review will involve conducting a comprehensive literature search of cohort, case–control, cross-sectional and randomised-controlled studies of the performance of host blood transcriptomic signatures for TB diagnosis and prediction of progression to TB disease. We will search Medline via PubMed, Scopus, Web of Science and EBSCO libraries, complemented by a search of bibliographies of selected articles for other relevant articles. The literature search will be restricted to studies published in English from 2005 to 2018 and conducted in HIV-uninfected adults and adolescents (≥12 years old). Forest plots and a narrative synthesis of the findings will be provided. The primary outcomes will be sensitivity, specificity, as well as true/false positives and true/false negatives. Heterogeneity resulting from differences in the design, composition and structure of individual signatures will preclude meta-analysis and pooling of results.Ethics and disseminationEthics approval is not required for this systematic review protocol. The results of this review will be disseminated through a peer-reviewed journal as well as conference presentations.PROSPERO registration numberCRD42017073817.

Source Of Information

Background: PROSPERO is an international prospective register for systematic review protocols. Many of the registrations are the only available source of information about planned methods. This study investigated the extent to which records in PROSPERO contained the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). Methods: A random sample of 439 single entry PROSPERO records of reviews of health interventions registered in 2018 was identified. Using a piloted list of 19 PRISMA-P items, divided into 63 elements, two researchers independently assessed the registration records. Where the information was present or not applicable to the review, a score of 1 was assigned. Overall scores were calculated and comparisons made by stage of review at registration, whether or not a meta-analysis was planned and whether or not funding/sponsorship was reported. Results: Some key methodological details, such as eligibility criteria, were relatively frequently reported, but much of the information recommended in PRISMA-P was not stated in PROSPERO registrations. Considering the 19 items, the mean score was 4.8 (SD 1.8; median 4; range 2-11) and across all the assessed records only 25% (2081/8227) of the items were scored as reported. Considering the 63 elements, the mean score was 33.4 (SD 5.8; median 33; range 18-47) and overall, 53% (14,469/27,279) of the elements were assessed as reported. Reporting was more frequent for items required in PROSPERO than optional items. The planned comparisons showed no meaningful differences between groups. Conclusions: PROSPERO provides reviewers with the opportunity to be transparent in their planned methods and demonstrate efforts to reduce bias. However, where the PROSPERO record is the only available source of a priori reporting, there is a significant shortfall in the items reported, compared to those recommended. This presents challenges in interpretation for those wishing to assess the validity of the final review.

Abstract Background: Depression is a chronic condition of high prevalence in the world population and associated with functional disability and compromises the physical health of affected individuals. According to Traditional Chinese Medicine (TCM), depression is associated with disability, there is not enough energy for positive feelings or associated with stagnation, when there is energy, but the flow of energy and emotions is blocked. Deficiency is also associated with excess in manic depression or irregularity in depression associated with anxiety. Auricular acupuncture, also known as auriculotherapy, it is part of a set of techniques based on TCM. For this, the auricular pavilion is related to 12 meridians, stimulating points in the ear and restoring the balance between blood and Qi (energy or vital force).Methods: This is a systematic review protocol for clinical trials prepared in accordance with the guidelines of the protocol Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA-P). Studies in which participants have any depressive disorder, diagnosed through standardized criteria such as the Diagnostic and Statistical Manual of Mental Disorders (DSM), the International Classification of Diseases (ICD) and other diagnostic criteria used internationally will be included. There will be no restrictions on age, gender, ethnicity, education or economic status. Studies will be accepted that have as experimental intervention any type of auricular acupuncture (using needles, seeds, magnetic stones, lasers, ultrasound, bleeding or electrical treatment). The control interventions that will be considered for the studies will be conventional medical treatment for each depressive disorder, no treatment, placebo and other active therapies. Discussion: Auricular acupuncture can be a potential alternative complementary treatment, it is low cost and has minimal side effects presented until now. With this review we hope to complete gaps in the knowledge of auricular acupuncture, promoting an updated and comprehensive synthesis of research on this topic. Record of systematic review: In accordance with the guidelines, our systematic review protocol was registered with the International Prospective Registry of systematic reviews (PROSPERO) on 10/27/2020 (registration number CRD42020211302).
