Abstract BACKGROUND: Post-thrombotic syndrome (PTS) is the most common long-term complication in pediatric deep venous thrombosis (DVT), affecting approximately 25% of children with an extremity DVT. PTS leads to a high physical, psychological and financial burden in affected patients. Although several risk factors have been associated with the development of pediatric PTS, few of them have been validated in the pediatric literature. A better understanding of the prognostic factors leading to PTS is a vital step for early identification of those children at greatest risk in order to develop risk-stratified interventions aimed at preventing this complication. AIM: To perform a systematic review and meta-analysis of available published evidence from the pediatric literature on prognostic factors for pediatric PTS. METHODS: A systematic search of MEDLINE, EMBASE, and the Cochrane Library from 1960 to December 2017 was performed. MeSH terms and search strategy employed were as follows: "postthrombotic syndrome" OR "postphlebitic syndrome" AND "all child 0-18 years" AND "young adult 19-24 years". A study was eligible for inclusion if it evaluated the development of PTS in pediatric patients (<21 years of age) with a confirmed extremity DVT and reported on at least one prognostic factor for the development of PTS. Single case reports, narrative reviews, and commentaries were excluded. Studies assessing the efficacy/safety of thrombolysis, and studies including patients >21 years of age with outcomes not reported by age group, were also excluded. Two reviewers independently screened all studies and extracted the data of interest. Data were analyzed using STATA v.15 statistical software. Meta-analyses were conducted for risk factors reported in at least three studies. Summary odds ratios (ORs) and 95% confidence intervals (CI) were calculated from the effect estimates from the individual studies using a random effects model. Statistical heterogeneity was quantified by I2 statistic. RESULTS: A total of 12 studies met the final inclusion criteria (Figure 1), nine cohort studies, two cross-sectional studies, and one case-control study. These studies reported a total of 1,160 patients with venous thromboembolism (VTE), of whom 938 (81%) were assessed for PTS (Table 1). Median age across studies ranged from 0.02 - 15.5 years. VTE was considered provoked in nearly 80% of patients. The most common reported risk factor for VTE was the presence of a central venous catheter (CVC, 54%) followed by congenital heart disease (26%). PTS was diagnosed in 46% (n=434) of patients with an extremity DVT. The median time from DVT diagnosis to PTS diagnosis ranged from 12 to 33 months across studies. Among studies reporting this information, mild PTS was most frequently diagnosed, followed by moderate and severe PTS (35%, 5% and 0.6% of patients respectively). Most common prognostic factors associated with PTS in individual studies included patient characteristics: age and gender; and DVT characteristics: recurrent DVT, symptomatic DVT, DVT degree of occlusion, and time between DVT diagnosis and PTS assessment. Three studies investigated the association of elevated factor VIII and d-dimer levels with PTS. Elevated levels of these biomarkers were found to be associated with development of adverse VTE outcomes in one study but this finding was not confirmed in the other studies. Meta-analysis of reported prognostic factors identified the presence of a CVC and occlusive DVT as significant risk factors for the development of pediatric PTS (OR= 1.8, 95%CI=1.08-2.98, and OR=1.89, 95%CI=1.04-3.46 respectively; Figure 2). CONCLUSION: Among 12 studies evaluating prognostic factors for PTS in children and meeting criteria for this meta-analysis, CVC-related DVT and complete occlusion were associated with pediatric PTS. Overall, high-quality evidence on pediatric PTS is lacking. Collaborative prospective cohort studies and trials that use validated pediatric PTS measures and standardized prognostic factor definitions are needed to better understand the risk factors associated with PTS.

Pooled Prevalence

Background A number of primary studies in Ethiopia address the prevalence of birth asphyxia and the factors associated with it. However, variations were seen among those studies. The main aim of this systematic review and meta-analysis was carried out to estimate the pooled prevalence and explore the factors that contribute to birth asphyxia in Ethiopia. Methods Different search engines were used to search online databases. The databases include PubMed, HINARI, Cochrane Library and Google Scholar. Relevant grey literature was obtained through online searches. The funnel plot and Egger’s regression test were used to see publication bias, and the I-squared was applied to check the heterogeneity of the studies. Cross-sectional, case-control and cohort studies that were conducted in Ethiopia were also be included. The Joanna Briggs Institute checklist was used to assess the quality of the studies and was included in this systematic review. Data entry and statistical analysis were carried out using RevMan 5.4 software and Stata 14. Result After reviewing 1,125 studies, 26 studies fulfilling the inclusion criteria were included in the meta-analysis. The pooled prevalence of birth asphyxia in Ethiopia was 19.3%. In the Ethiopian context, the following risk factors were identified: Antepartum hemorrhage(OR: 4.7; 95% CI: 3.5, 6.1), premature rupture of membrane(OR: 4.0; 95% CI: 12.4, 6.6), primiparas(OR: 2.8; 95% CI: 1.9, 4.1), prolonged labor(OR: 4.2; 95% CI: 2.8, 6.6), maternal anaemia(OR: 5.1; 95% CI: 2.59, 9.94), low birth weight(OR = 5.6; 95%CI: 4.7,6.7), meconium stained amniotic fluid(OR: 5.6; 95% CI: 4.1, 7.5), abnormal presentation(OR = 5.7; 95% CI: 3.8, 8.3), preterm birth(OR = 4.1; 95% CI: 2.9, 5.8), residing in a rural area (OR: 2.7; 95% CI: 2.0, 3.5), caesarean delivery(OR = 4.4; 95% CI:3.1, 6.2), operative vaginal delivery(OR: 4.9; 95% CI: 3.5, 6.7), preeclampsia(OR = 3.9; 95% CI: 2.1, 7.4), tight nuchal cord OR: 3.43; 95% CI: 2.1, 5.6), chronic hypertension(OR = 2.5; 95% CI: 1.7, 3.8), and unable to write and read (OR = 4.2;95%CI: 1.7, 10.6). Conclusion According to the findings of this study, birth asphyxia is an unresolved public health problem in the Ethiopia. Therefore, the concerned body needs to pay attention to the above risk factors in order to decrease the country’s birth asphyxia.

IntroductionStudies suggest that the prevalence of food allergy may be increasing worldwide. Results regarding the prevalence and features of adverse food reactions older people have, however, scarcely been analysed in the literature. Thus, the objective of the present systematic review will be to describe the prevalence of food allergy in older individuals, its risk factors, clinical features, as well as the most frequently and commonly involved foods.Methods and analysisWe will conduct a systematic review and meta-analysis of the incidence, prevalence and risk factors for food allergy in older individuals. We will search international electronic databases including MEDLINE, EMBASE, Cochrane Library, CINAHL, AMED and ISI Web of Science for published, unpublished and ongoing studies from 1980 toJanuary 2019. There will be no restriction on the language or geography of publication. We will use the critical appraisal skills programme quality assessment tool to appraise the methodological quality of included studies. A descriptive summary with data tables will be elaborated, and if deemed clinically relevant and statistically adequate, meta-analysis using random-effects modelling will be carried out, given the expected clinical, methodological and statistical heterogeneity of studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist will guide reporting of the systematic review.Ethics and disseminationSince this systematic review will be solely based on published and retrievable literature, no ethics approval will be obtained. This study will allow us to draw up-to-date estimates of the prevalence of adverse food reactions in older individuals, worldwide, besides allowing the identification of its major risk factors, clinical manifestations and predominant foods responsible for such reactions. A multidisciplinary team has been assembled for this systematic review and will participate in relevant dissemination activities, namely reports, publications and presentations.PROSPERO registration numberCRD42018102140

Objective: The purpose of this study was assess the time trend of the prevalence of prediabetes and diabetes and risk factors associated with diabetes in Pakistan by using a systematic review and meta–analysis. Methods: A systematic literature search of Embase, PubMed, and the Cochrane library was carried out between January 1, 1995 and August 30, 2018. Diabetes and prediabetes prevalence estimates were combined by the random–effects model. The existence of publication bias was tested by Egger regression. This systematic review was reported following the PRISMA guidelines. Results: The search conceded a total of 635 studies, only 14 studies were considered for meta-analysis. The prevalence of diabetes in Pakistan was revealed 14.62% (10.651%–19.094%; 14 studies) based on 49,418 people using the inverse–variance random–effects model. The prevalence of prediabetes was 11.43% (8.26%–15.03%; 10 studies) based on a total sample of 26,999 people. The risk factors associated with diabetes were mean age (β = 0.48%, 95% CI: 0.21–0.78, p<0.001), the proportion of participants with a family history of diabetes (β = 0. 45%, 95% CI: 0.08–0.82, p =0.018, p<0.001), hypertension (β = 0.40%, 95% CI: 0.06–0.75, p = 0.022), weight (BMI) (β = 0.21%, 95% CI: 0.02–0.4, p=0.030). Conclusions: There has been a continuous increase in the prevalence of prediabetes and diabetes in Pakistan. All parts of the country have been affected, with the highest in Sindh and lowest in Khyber Pakhtunkhwa. The main factors include growing age, family history, hypertension and obesity. A nationwide diabetes care survey on risk factors and prevention policy is highly recommended. doi: https://doi.org/10.12669/pjms.35.4.194 How to cite this:Akhtar S, Nasir JA, Abbas T, Sarwar A.

Abstract Background: Infection with resistant Pseudomonas aeruginosa (RPA) in Intensive Care Unit (ICU) is known to be either endogenous or exogenous or both, but the roles of each of these contamination routes is yet to be clarified. Data regarding prevalence, risk factors and environmental factors associated with RPA in ICU are very scanty and even when they exist, they seem to be contradictory. So, there is a strong interest in understanding both individual and environmental factors associated with RPA infection. This systematic review aims to investigate individual and environmental factors associated with the colonization and infection with RPA in ICU.Methodology: MEDLINE (Pubmed), EMBASE (OVID), the Cochrane Library (Wiley), Web of Science, CINAHL (EBSCOHost) and LILACS (BIREME) will be searched from inception onwards. Grey literature will be identified through Google Scholar and open Grey. Two reviewers will independently screen all citations, abstracts and full-text articles. Potential conflicts will be resolved through discussion. Methodological quality including bias will be appraised using appropriate approaches. A narrative synthesis will describe quality and content of the epidemiological evidence. Prevalence, Odds ratio, Relative Risk, Hazard radio with their respective 95% confidence intervals will be calculated. A meta-analysis of data extracted from eligible studies with similar population and RPA testing will be performed. The analysis will evaluate factors influencing the estimates. A random effect model will be used to summarize effect sizes.Discussion: Two contrasting hypotheses on risk factors of acquisition, colonisation, and infection of RPA are being debated, especially in a context where available data are scanty or exhibit high discrepancy. Indeed, most of the reviews have been focalized on hospitalised patients, and not in ICU, and few of them really address the environmental factors issue. To fill that gap, this review will combine both analysis of individual and environmental risk factors using prevalence study in ICU and evaluation of different methodologies. These two hypotheses will be tested and challenged, and could serve as a basis for a more in-depth studies to fill the methodological gaps that will be identified as part of this current review.Systematic review registration: This protocol has been submitted registered with Prospective Register of Systematic Reviews (PROSPERO) on 07 march 2021 under number CRD42021233832

IntroductionMild cognitive impairment (MCI) often represents the earliest stage of Alzheimer’s disease. There has been considerable research investigating specific risk factors regarding the progression from normal cognition to MCI. However, different studies have come to different conclusions on the impact of particular risk factors. Therefore, it is necessary to conduct a meta-analysis of the risk factors that predict cognitive disruption in individuals based on associations with MCI.Methods and analysisWe will search seven electronic databases without time limit, including MEDLINE, EMBASE, The Cochrane Library, Web of Science, China National Knowledge Infrastructure, the Wan Fang Database and China Biology Medicine. Two researchers will independently screen for eligibility and perform data extraction. Data were extracted from cohort studies meeting the inclusive criteria according to the Newcastle Ottawa Scale (NOS) methods. A third member of the research team will be contacted when a consensus cannot be reached. Any disagreement will be settled by consensus. The NOS will be used to assess the quality of the studies. All analyses were performed using Stata V.15.1.Ethics and disseminationWe will report this review in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. We will disseminate our findings through a publication in a peer-reviewed journal.

Chronic Post Surgical Pain

IntroductionChronic post-surgical pain (CPSP) after lung or pleural surgery is a common complication and associated with a decrease in quality of life, long-term use of pain medication and substantial economic costs. An abundant number of primary prognostic factor studies are published each year, but findings are often inconsistent, methods heterogeneous and the methodological quality questionable. Systematic reviews and meta-analyses are therefore needed to summarise the evidence.Methods and analysisThe reporting of this protocol adheres to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) checklist. We will include retrospective and prospective studies with a follow-up of at least 3 months reporting patient-related factors and surgery-related factors for any adult population. Randomised controlled trials will be included if they report on prognostic factors for CPSP after lung or pleural surgery. We will exclude case series, case reports, literature reviews, studies that do not report results for lung or pleural surgery separately and studies that modified the treatment or prognostic factor based on pain during the observation period. MEDLINE, Scopus, Web of Science, Embase, Cochrane, CINAHL, Google Scholar and relevant literature reviews will be searched. Independent pairs of two reviewers will assess studies in two stages based on the PICOTS criteria. We will use the Quality in Prognostic Studies tool for the quality assessment and the CHARMS-PF checklist for the data extraction of the included studies. The analyses will all be conducted separately for each identified prognostic factor. We will analyse adjusted and unadjusted estimated measures separately. When possible, evidence will be summarised with a meta-analysis and otherwise narratively. We will quantify heterogeneity by calculating the Q and I2 statistics. The heterogeneity will be further explored with meta-regression and subgroup analyses based on clinical knowledge. The quality of the evidence obtained will be evaluated according to the Grades of Recommendation Assessment, Development and Evaluation guideline 28.Ethics and disseminationEthical approval will not be necessary, as all data are already in the public domain. Results will be published in a peer-reviewed scientific journal.PROSPERO registration numberCRD42021227888.

ABSTRACT BACKGROUND Intracranial arteriovenous malformation (AVM) is a congenital lesion that can potentially lead to devastating consequences if not treated. Many institutional cohort studies have reported on the outcomes after radiosurgery and factors associated with successful obliteration in the last few decades. OBJECTIVE To quantitatively assess the dose-response relationship and risk factors associated with AVM obliteration using a systematic review and meta-analysis approach. METHODS Data were extracted from reports published within the last 20 yr. The dose-response fit for obliteration as a function of marginal dose was performed using inverse-variance weighting. Risk factors for AVM obliteration were assessed by combining odds ratios from individual studies using inverse-variance weighting. RESULTS The logistic model fit showed a clear association between higher marginal dose and higher rates of obliteration. There appeared to be a difference in the steepness in dose-response when comparing studies with patients treated using Gamma Knife radiosurgery (Elekta), compared to linear accelerators (LINACs), and when stratifying studies based on the size of treated AVMs. In the risk-factor analysis, AVM obliteration rate decreases with larger AVM volume or AVM diameter, higher AVM score or Spetzler-Martin (SM) grade, and prior embolization, and increases with compact AVM nidus. No statistically significant associations were found between obliteration rate and age, sex, prior hemorrhage, prior aneurysm, and location eloquence. CONCLUSION A marginal dose above 18 Gy was generally associated with AVM obliteration rates greater than 60%, although lesion size, AVM score, SM grade, prior embolization, and nidus compactness all have significant impact on AVM obliteration rate.

IntroductionDelirium in the postoperative period is a wide-reaching problem that affects important clinical outcomes. The incidence and risk factors of delirium in individuals with acute myocardial infarction (AMI) after primary percutaneous coronary intervention (PCI) has not been completely determined and no relevant systematic review and meta-analysis of incidence or risk factors exists. Hence, we aim to conduct a systematic review and meta-analysis to ascertain the incidence and risk factors of delirium among AMI patients undergoing PCI.Methods and analysesWe will undertake a comprehensive literature search among PubMed, EMBASE, Cochrane Library, PsycINFO, CINAHL and Google Scholar from their inception to the search date. Prospective cohort and cross-sectional studies that described the incidence or at least one risk factor of delirium will be eligible for inclusion. The primary outcome will be the incidence of postoperative delirium. The quality of included studies will be assessed using a risk of bias tool for prevalence studies and the Cochrane guidelines. Heterogeneity of the estimates across studies will be assessed. Incidence and risk factors associated with delirium will be extracted. Incidence data will be pooled. Each risk factor reported in the included studies will be recorded together with its statistical significance; narrative and meta-analytical approaches will be employed. The systematic review and meta-analysis will be presented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.Ethics and disseminationThis proposed systematic review and meta-analysis is based on published data, and thus there is no requirement for ethics approval. The study will provide an up to date and accurate incidence and risk factors of delirium after PCI among patients with AMI, which is necessary for future research in this area. The findings of this study will be disseminated through publication in a peer-reviewed journal.PROSPERO registration numberCRD42020184388.
