IntroductionIt is widely assumed that sepsis is a life-threatening systemic inflammation caused by a dysregulated host response to infection mediated by an increase in multiple proinflammatory cytokines. The levels of key proinflammatory cytokines tumour necrosis factor, interleukin-1β and interferon γ are poorly characterised during sepsis. We believe this project will produce a ‘gold-standard’ document to which other reports on cytokine levels will be compared. The objective of this systematic review will be to identify key cytokine circulating levels in patients with sepsis and assess the association between these levels and morbidity and mortality outcomes related to sepsis.Methods and analysisWe would include reports of any design except for case reports. Sepsis patients will comprise those with a diagnosis of sepsis, severe sepsis or septic shock. The primary exposure is levels of three proinflammatory cytokines. The primary outcome is mortality at 28 or 30 days. Study subjects can be of any age, sex or ethnicity. Studies will be restricted to the English language. Medline, Embase, Cochrane Library and Web of Science Core Collection will be searched for eligible studies. A database search will include studies from 1985 to May 2020. Two reviewers will independently screen and select studies, assess methodological quality and extract data. A meta-analysis will be performed, if possible, and the Grading of Recommendations Assessment Development and Evaluation Summary of Findings presented.Ethics and disseminationFormal ethical approval is not required as data will be extracted from existing literature. This systematic review will be disseminated through a peer-reviewed publication and at conference meetings.PROSPERO registration numberCRD42020179800.

IntroductionPrevalence of suicidal ideation (SI) and behaviours are higher among patients with cancer than general population. No systematic review/meta-analysis investigated this topic; therefore, our aim will be to assess the relationship between cancer and SI and behaviours.MethodsWe will search PubMed/MEDLINE, EMBASE, SCOPUS, Web of Science, PsycINFO and Cochrane Library databases from their inception until 30 June 2018. Case–control and cohort studies focused on the association between cancer (any type) and suicidal outcomes (suicide, suicide attempt and SI) will be included. Two team members will independently: (A) perform the selection of the included studies and data extraction, with the supervision of a third member in case of discrepancies and (B) assess each study with: (1) Newcastle-Ottawa Scale (NOS); (2) Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement; (3) Grading of Recommendations Assessment, Development and Evaluation (GRADE). We will conduct a random-effects meta-analysis. Individual and pooled ORs and associated 95% CIs will be calculated as well as between-study heterogeneity. We will examine the potential for publication bias. If possible, we will explore reasons for potential between-study heterogeneity.Ethics and disseminationThis study does not require ethical approval. The study will be submitted to a peer-reviewed journal, will be publicly disseminated and will be the topic of research presentations.PROSPERO registration numberCRD42017072482.

IntroductionPatients with lung cancer often experience heavy psychological distress, especially depression, which results in poorer quality of life, shorter survival time and greater mortality. Our aim is to summarise data on the prevalence and risk factors of depression in patients with lung cancer.Methods and analysisWe will search PubMed, EMBASE, MEDLINE, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang and Chinese Biomedicine Literature Database (SinoMed) for studies on the prevalence and risk factors of depression in patients with lung cancer, which should be published from 1 January 1975 to 25 November 2018 in English/Chinese. Two reviewers will independently screen studies, extract data and assess the risk of bias. We will use RevMan V.5.0 and STATA V.12.0 software for statistical analysis. The I² test will be used to identify the extent of heterogeneity. Publication bias will be assessed by generating a funnel plot and performing the Begg and Egger test. The quality of the systematic review will be evaluated using the AMSTAR (‘A Measurement Tool to Assess Systematic Reviews’) criteria and ‘The Grading of Recommendations Assessment, Development and Evaluation’.Ethics and disseminationSince this is a review involving analysis of publicly available data, ethical approval is not required. The final results of this study will be published in a peer-reviewed journal.PROSPERO registration numberCRD42018118167.

Purpose The aim of this work is to assess the clinical outcomes of implants placed after a nasal floor elevation procedure. Methods A systematic review was conducted using four electronic databases; Medline (Pubmed), Cochrane library, DOAJ and SCOPUS, following the PRISMA statement recommendations to answer the PICO question: “In patients undergoing dental implant placement in the maxillary anterior region (P), Do implants placed after nasal floor elevation (I) have a different survival (O) from those implants placed without grafting procedures (C)?. The study was pre-registered in PROSPERO (CRD42021229479). Included articles quality was assessed using the “NIH quality assessment tool”, “The Newcastle-Ottawa scale” and “JBI critical appraisal tools for case reports''. Results Twelve articles were finally selected, including 151 patients and 460 implants. The weighted mean follow-up was 32.2 months, and the weighted survival rate after this period was 97.64% (range 89.2-100%). No statistical differences could be inferred between the treatments performed in one-stage or two-stage, following a lateral approach or a transcrestal approach or using different grafting materials. A great heterogeneity was found in terms of study design and methodological aspects. For this reason, a quantitative analysis followed by meta-analysis was not possible. Conclusion Within the limitations of this study, implants placed after a nasal floor elevation present a good survival and a low range of complications. In absence of randomized studies, the level of evidence was low, attending the GRADE system and based on the study quality level, the strength of evidence attending the SORT taxonomy was B.

Abstract Background Early provision of palliative care, at least 3–4 months before death, can improve patient quality of life and reduce burdensome treatments and financial costs. However, there is wide variation in the duration of palliative care received before death reported across the research literature. This study aims to determine the duration of time from initiation of palliative care to death for adults receiving palliative care across the international literature. Methods We conducted a systematic review and meta-analysis that was registered with PROSPERO (CRD42018094718). Six databases were searched for articles published between Jan 1, 2013, and Dec 31, 2018: MEDLINE, Embase, CINAHL, Global Health, Web of Science and The Cochrane Library, as well undertaking citation list searches. Following PRISMA guidelines, articles were screened using inclusion (any study design reporting duration from initiation to death in adults palliative care services) and exclusion (paediatric/non-English language studies, trials influencing the timing of palliative care) criteria. Quality appraisal was completed using Hawker’s criteria and the main outcome was the duration of palliative care (median/mean days from initiation to death). Results One hundred sixty-nine studies from 23 countries were included, involving 11,996,479 patients. Prior to death, the median duration from initiation of palliative care to death was 18.9 days (IQR 0.1), weighted by the number of participants. Significant differences between duration were found by disease type (15 days for cancer vs 6 days for non-cancer conditions), service type (19 days for specialist palliative care unit, 20 days for community/home care, and 6 days for general hospital ward) and development index of countries (18.91 days for very high development vs 34 days for all other levels of development). Forty-three per cent of studies were rated as ‘good’ quality. Limitations include a preponderance of data from high-income countries, with unclear implications for low- and middle-income countries. Conclusions Duration of palliative care is much shorter than the 3–4 months of input by a multidisciplinary team necessary in order for the full benefits of palliative care to be realised. Furthermore, the findings highlight inequity in access across patient, service and country characteristics. We welcome more consistent terminology and methodology in the assessment of duration of palliative care from all countries, alongside increased reporting from less-developed settings, to inform benchmarking, service evaluation and quality improvement.

IntroductionPneumoconiosis is characterised by diffuse fibrosis in lung tissue, and its incidence is on the rise. At present, there are limited therapeutic options for pneumoconiosis. Pulmonary rehabilitation (PR) has been widely used to treat pneumoconiosis，however, there is limited evidence concerning its efficacy. Therefore, we plan to conduct a systematic review to investigate the efficacy and safety of PR for pneumoconiosis.Methods and analysisThe following databases will be searched from their inception to 1 April 2019: PubMed, Embase, The Cochrane Library, Web of Science, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chongqing VIP and Wanfang Data. Randomised controlled trials of PR for pneumoconiosis will be included. Primary outcomes will include 6 min walk distance and St. George’s Respiratory Questionnaire. Study selection, extraction of data and assessment of study quality each will be independently undertaken. Statistical analysis will be conducted using Review Manager software.Ethics and disseminationThis systematic review will provide up-to-date information on PR for pneumoconiosis. The review does not require ethical approval and will be disseminated electronically through a peer-reviewed publication or conference presentations.PROSPERO registration numberCRD42018095266.

The Impact

150 Background: Nearly 50% of men diagnosed with prostate cancer may receive treatment with some form of androgen deprivation therapy (ADT). While some side effects of ADT are well acknowledged, the specific impact of ADT on cognitive function is uncertain. Our objective was to perform a systematic review and meta-analysis assessing the impact of ADT on overall cognitive decline, and the risks of Alzheimers, Parkinson’s disease. Methods: Relevant studies were identified through search of English language articles indexed in PubMed Medline, PsycINFO, Cochrane Library and Web of Knowledge/Science. First, we assessed rates of cognitive decline in five cohorts from three studies. Second, we assessed rates of Alzheimer’s or Parkinson disease using three large retrospective studies. A pooled-analysis was conducted using a meta-analysis. Weighted averages were reported as odds ratios (OR) with 95% confidence intervals (CI) using RevMan and a DerSimonian and Laird random-effects model. The heterogeneity test was measured using the Q-Mantel-Haenszel ( P< 0.10 was considered of significant heterogeneity). Results: With respect to overall cognitive decline (defined as scoring 1.5 standard deviations [SD] in two or more objective cognitive tests), patients receiving ADT had higher odds of overall cognitive decline than patients with prostate cancer not treated with ADT or health controls (OR: 2.03, 95% CI: 1.42–2.90). Furthermore, men with a history of ADT for prostate cancer had higher odds of developing Alzheimer’s and Parkinson dementia compared to men with prostate cancer not treated with ADT (OR: 1.32, 95% CI: 1.27–1.37). Conclusions: Men receiving ADT for prostate cancer performed significantly worse on measures of overall cognitive function. Additionally, results from the three large observational trials included suggest men exposed to ADT for prostate cancer have higher rates of Parkinson/Alzheimer’s compared to men without ADT.

Abstract Reporting

Background: An increasing number of systematic reviews are published on an annual basis. Although perusal of the full text of articles is preferable, abstracts are sometimes relied upon to guide clinical decisions. Despite this, the abstracts of systematic reviews have historically been poorly reported. We evaluated the reporting quality of systematic review abstracts within hand and wrist pathology literature. Methods: We searched MEDLINE®, EMBASE and Cochrane Library from inception to December 2017 for systematic reviews in hand and wrist pathology using the 12-item PRISMA-A checklist to assess abstract reporting quality. Results: A total of 114 abstracts were included. Most related to fracture (38%) or arthritis (17%) management. Forty-seven systematic reviews (41%) included meta-analysis. Mean PRISMA-A score was 3.6/12 with Cochrane reviews having the highest mean score and hand-specific journals having the lowest. Abstracts longer than 300 words (mean difference [MD]: 1.43, 95% CI [0.74, 2.13]; p <0.001) and systematic reviews with meta-analysis (MD: 0.64, 95% CI [0.05, 1.22]; p = 0.034) were associated with higher scores. Unstructured abstracts were associated with lower scores (MD: –0.65, 95% CI [–1.28, –0.02]; p = 0.044). A limitation of this study is the possible exclusion of relevant studies that were not published in the English language. Conclusion: Abstracts of systematic reviews pertaining to hand and wrist pathology have been suboptimally reported as assessed by the PRISMA-A checklist. Improvements in reporting quality could be achieved by endorsement of PRISMA-A guidelines by authors and journals, and reducing constraints on abstract length.

Abstract Background: ALT value is often used to reflect the hepatic inflammation and injury in NAFLD patients, but many studies proved that ALT values were normal in many NAFLD patients. The aim of this study was to identify the summarized proportion of NAFLD patients with normal ALT value in the overall NAFLD patients. Methods: Electronic databases PubMed, EMBASE, Ovid, and the Cochrane Library were searched for potential studies published from January 1, 2000 to September 30, 2019. Studies that have reported the number of NAFLD or NASH patients with normal and abnormal ALT value were included and analyzed. Abstracts, reviews, case reports, and letters were excluded. Results: A total of 11 studies with 4084 patients were included for assessing the summarized proportion of NAFLD patients with normal ALT in overall NAFLD patients. As the results shown, the summarized proportion of NAFLD patients with normal ALT value in overall NAFLD patients was 25% (95%CI: 20%-31%) which was calculated by the random-effects model. The summarized proportion of NASH patients with normal ALT value in overall NASH patients was 19% (95%CI: 13%-27%). Subgroup analysis includes region, study type, diagnostic method, and group size were conducted to investigate the resource of heterogeneity in the summarized proportion of NAFLD and NASH patients with normal ALT value. Conclusions: 25% NAFLD patients and 19% NASH patients possess the normal ALT value in the clinical manifestation. The value of ALT in the clinical diagnosis of NAFLD and NASH remains need be further testified.

Cytokine Levels

Abstract Background Sepsis is a global health problem associated with significant morbidity and mortality and is attributed to a “cytokine storm.”. However, anti-cytokine therapies have failed to lower sepsis mortality in clinical trials. Linking cytokine excess to sepsis pathogenesis requires quantification of cytokine levels in sepsis. This systematic review and meta-analysis characterizes levels of key cytokines in the circulation of sepsis patients and relates TNFα levels to mortality and patient characteristics. Methods Medline, Embase, Cochrane Library, and Web of Science Core Collection databases were searched from 1946 to May 2020 for studies in English disclosing cytokine levels in sepsis. Keywords included sepsis, septic shock, purpura fulminans, and tumor necrosis factor (TNF)α. We related cytokine amounts to 28-day mortality. Data analyses were performed using a random-effects model to estimate pooled odds ratios (OR) and 95% confidence intervals (CI). This systematic review is registered in PROSPERO under number CRD42020179800. Results A total of 3656 records were identified. After exclusions, 103 studies were included. Among these studies, 72 disclosed TNFα levels, 25 showed interleukin (IL)-1β levels, and 6 presented interferon (IFN)γ levels. The pooled estimate mean TNFα concentration in sepsis patients was 58.4 pg/ml (95% CI, 39.8-85.8 pg.ml; I2 = 99.4%). Pooled estimate means for IL-1α and IFNγ in sepsis patients were 21.8 pg/ml (95% CI, 12.6-37.8 pg.ml; I2 =99.8%) and 63.3 pg/ml (95% CI, 19.4-206.6 pg/ml; I2 = 99.7%), respectively. Elevated TNFα concentrations were associated with increased 28-day mortality (P=0.001). In a subgroup analysis, TNFα levels did not relate to sepsis source, sepsis severity, or sequential organ failure assessment (SOFA) score (figure 1). In a metaregression, TNFα associated with age, percentage of females and mortality at 28 days. Figure 1: A: TNFa levels according to sepsis source. B: TNFa levels according to measurement technique. C: TNFa levels according to presence or absence of cardiovascular disease. D: TNFa levels according to presence or absence of malignancy. E: TNFa levels according to sepsis severity. F: TNFa levels in fungal compared to other causes of sepsis (Yes=fungal sepsis; No= Other types of sepsis). G: TNFa levels according to SOFA score. H: TNFa levels and mortality at 28 days. Conclusion We presented levels of TNFα, IL-1β, and IFNγ in human sepsis and showed that TNFα elevations are associated with sepsis mortality. TNFα concentrations did not correlate with sepsis severity. We believe the concept that elevated cytokines cause sepsis should be revisited in the context of these data.

Abstract Background Self-medication of medicines is a global issue particularly among those with good access and familiarity with medications such as university students. It has a significant impact on drug resistance and medication-related complications. There are limited and inconsistent studies on self-medication practices in Ethiopia. The aim of this systematic review and meta-analysis was to estimate the pooled prevalence of self-medication and its predictors among university students in Ethiopia. Methods A systematic review and meta-analysis was conducted to assess the prevalence and predictors of self-medication among university students in Ethiopia. Published articles from various electronic databases such as Medline, Hinari, Pub Med, Cochrane library, and the Web of Science were accessed. In addition, a manual search was performed including Google Scholar. Searching of articles were searched from January 1st to February 1, 2021. All observational studies conducted among university students in English language were included in the review. Two reviewers independently assessed articles before inclusion in the final review using the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) instrument for critical appraisal. The I2 test was used to assess heterogeneity. Since the included studies exhibited high heterogeneity, a random-effects model was used to estimate the pooled prevalence of self-medication. Results We found of 812 published and unpublished studies in our search. Finally, 31 full-text studies were reviewed, and 13 studies fulfilled the inclusion criteria and were included in the final meta-analysis. A total of 5377 study respondents from 13 studies were included in the study. The results of our study revealed that the pooled prevalence of self-medication among university students was 49.41% (95% CI 38.67%, 60.13%). The included studies had a sample size ranging from 250 to 792 with the lowest prevalence (19.87%) of self-medication from the University of Gondar, whereas the highest prevalence (77.01%) was recorded in a study conducted at Arsi University. From the pooled estimation, there was a significant association between self-medication and income (OR = 0.67: 95% CI 0.55–0.80). However, the association between self-medication and year of study and sex of participants was insignificant. Conclusion The pooled prevalence of self-medication among Ethiopian university students was relatively high compared to the current global health problem with an increase in anti-microbial resistance. Health professionals and concerned bodies should pay attention to raising awareness regarding the consequences of using medications without prescription.
