Prediction of mortality in adult patients with sepsis using six biomarkers: a systematic review and meta-analysis

Abstract Background Angiopoietin-1 (Ang-1) and 2 (Ang-2), high mobility group box 1 (HMGB1), soluble receptor for advanced glycation endproducts (sRAGE), soluble triggering receptor expressed on myeloid cells 1 (sTREM1), and soluble urokinase-type plasminogen activator receptor (suPAR) have shown promising results for predicting all-cause mortality in critical care patients. The aim of our systematic review and meta-analysis was to assess the prognostic value of these biomarkers for mortality in adult patients with sepsis. Methods A systematic literature search of the MEDLINE, PubMed, EMBASE, and Cochrane Library databases, for articles in English published from 01.01.1990 onwards, was conducted. The systematic review focused exclusively on observational studies of adult patients with sepsis, any randomized trials were excluded. For the meta-analysis, only studies which provide biomarker concentrations within 24 h of admission in sepsis survivors and nonsurvivors were included. Results are presented as pooled mean differences (MD) between nonsurvivors and survivors with 95% confidence interval for each of the six biomarkers. Studies not included in the quantitative analysis were narratively summarized. The risk of bias was assessed in all included studies using the Quality in Prognosis Studies (QUIPS) tool. Results The systematic literature search retrieved 2285 articles. In total, we included 44 studies in the qualitative analysis, of which 28 were included in the meta-analysis. The pooled mean differences in biomarker concentration (nonsurvivors − survivors), measured at onset of sepsis, are listed as follows: (1) Ang-1: − 2.9 ng/ml (95% CI − 4.1 to − 1.7, p < 0.01); (2) Ang-2: 4.9 ng/ml (95% CI 2.6 to 7.1, p < 0.01); (3) HMGB1: 1.2 ng/ml (95% CI 0.0 to 2.4, p = 0.05); (4) sRAGE: 1003 pg/ml (95% CI 628 to 1377, p < 0.01); (5) sTREM-1: 87 pg/ml (95% CI 2 to 171, p = 0.04); (6) suPAR: 5.2 ng/ml (95% CI 4.5 to 6.0, p < 0.01). Conclusions Ang-1, Ang-2, and suPAR provide beneficial prognostic information about mortality in adult patients with sepsis. The further development of standardized assays and the assessment of their performance when included in panels with other biomarkers may be recommended. Trial registration This study was recorded on PROSPERO, prospective register of systematic reviews, under the registration ID: CRD42018081226

The Relationship

Abstract Background Published studies have shown contradictory results regarding the relationship between somatometric parameters and varicoceles. We performed a systematic review and meta-analysis to investigate the possible effects of age, height, weight, and body mass index (BMI) on the presence and severity of varicoceles. Methods Databases including EMBASE, MEDLINE, PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Web of Science, and Google Scholar were systematically searched to identify relevant articles published up to March 2020. Two researchers independently identified eligible articles and extracted data. Cochran’s Q statistic and I2 statistics were used to assess heterogeneity. Meta-analysis was performed using StataSE 12.0 software (StataCorp LP, USA). Random-effects models were used to obtain the weighted mean differences (WMDs) and 95% confidence intervals (CIs). Publication bias was assessed using Begg’s funnel plot and Egger’s regression test. Results The search strategy produced 272 articles, of which 18 articles were eligible according to the inclusion/exclusion criteria. A total of 56,325 patients with varicocele and 1,334,694 patients without varicocele were included in the meta-analysis to evaluate the effect of somatometric parameters on the presence and severity of varicocele. The overall results demonstrated that the presence of varicoceles was significantly associated with height (WMD = 1.41, 95% CI = 1.07 to 1.74, P < 0.001) and inversely correlated with BMI (WMD = − 1.35, 95% CI = -1.67 to − 1.03, P < 0.001) but not with age (WMD = -0.93, 95% CI = -2.19 to 0.33, P = 0.149) or weight (WMD = 0.24, 95% CI = -2.24 to 2.72, P = 0.850). The severity of varicocele was inversely correlated with increased BMI but not with age. Conclusion The presence of varicoceles was significantly associated with height and inversely correlated with BMI.

Background: This study aimed to synthesize the evidence of the effect of practicing Tai Chi on oxidative stress markers (OxSM). Methods: This systematic review and meta-analysis was conducting using the MEDLINE, Cochrane Library, ScienceDirect, Scopus, Epistemonikos, Lilacs, and Ovid databases to identify randomized (RCT) and non-randomized (NRCT) clinical trials that evaluated the Tai Chi effect on OxSM compared to sedentary behavior, walking or yoga. Pooled mean differences (MDs) with 95% confidence intervals (95%CI) were estimated using the inverse variance method to determine the effect of Tai Chi on OxSM. PROSPERO register: CRD42019138362. Results: Five RCT and five NRCT were included. Compared to sedentary behavior, regular Tai Chi practice increases the levels of the enzymes superoxide dismutase (MD = 34.97 U/mL, (95%CI, 9.45 to 60.48), 344 participants) and catalase (MD = 15.63 U/mL, (95%CI, 4.05 to 27.22), 110 participants), as well as reducing the levels of lipoperoxides (MD = −0.02 µmol/L, (95%CI, −0.04 to −0.00), 234 participants). For comparisons with walking or yoga, only one study per activity was identified comparing the effect on OxSM. Conclusions: Regular Tai Chi practice increases the levels of superoxide dismutase and catalase, as well as reducing the levels of lipoperoxides. More studies are necessary to determine the effect of Tai Chi on OxSM when compared to other physical activities.

The Impact

Background: The impact of magnetic resonance imaging–detected extramural vascular invasion (mrEMVI) in distant metastasis is well known but its correlation with prevalence of lymph node metastasis is less studied. The aim of this systematic review and meta-analysis was to assess the prevalence of nodal disease in mrEMVI–positive and negative cases in rectal cancer. Methods: Following guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses, a systematic literature search in PubMed, Web of Science, Cochrane Library, and EMBase was carried out to identify relevant studies published up to May 2019. Results: Our literature search generated 10 studies (863 and 1212 mrEMVI–positive and negative patients, respectively). The two groups (mrEMVI–positive and negative) were significantly different in terms of nodal disease status (odds ratio [OR] 3.15; 95% confidence interval [CI] 2.12–4.67; p < 0.001). The prevalence of nodal disease was 75.90% vs 52.56% in the positive mrEMVI vs negative mrEMVI group, respectively ( p < 0.001). The prevalence of positive lymph node in positive mrEMVI patients treated with neoadjuvant/adjuvant chemoradiotherapy (nCRT/CRT) (OR 2.47; 95% CI 1.65–3.69; p < 0.001) was less compared with the patients who underwent surgery alone (OR 6.25; 95% CI 3.74–10.44; p < 0.001). Conclusion: The probability of positive lymph nodes in cases of positive mrEMVI is distinctly greater compared with negative cases in rectal cancer. Positive mrEMVI indicates risk of nodal disease prevalence increased by threefold in rectal cancer.

Enamel Formation

Previous studies have reported the association between multiple genetic variants in enamel formation-related genes and the risk of dental caries with inconsistent results. We performed a systematic literature search of the PubMed, Cochrane Library, HuGE and Google Scholar databases for studies published before March 21, 2020 and conducted meta-, gene-based and gene-cluster analysis on the association between genetic variants in enamel- formation-related genes and the risk of dental caries. Our systematic literature search identified 21 relevant publications including a total of 24 studies for analysis. The genetic variant rs17878486 in AMELX was significantly associated with dental caries risk (OR=1.40, 95% CI: 1.02-1.93, P=0.037). We found no significant association between the risk of dental caries with rs12640848 in ENAM (OR=1.15, 95% CI: 0.88-1.52, P=0.310), rs1784418 in MMP20 (OR=1.07, 95% CI: 0.76-1.49, P=0.702) and rs3796704 in ENAM (OR=1.06, 95% CI: 0.96-1.17, P=0.228). Gene-based analysis indicated that multiple genetic variants in AMELX showed joint association with the risk of dental caries (6 variants; P<10-5), so did genetic variants in MMP13 (3 variants; P=0.004), MMP2 (3 variants; P<10-5), MMP20 (2 variants; P<10-5) and MMP3 (2 variants; P<10-5). The gene-cluster analysis indicated a significant association between the genetic variants in this enamel-formation gene cluster and the risk of dental caries (P<10-5). The present meta-analysis revealed that genetic variant rs17878486 in AMELX were associated with dental caries, and multiple genetic variants in enamel-formation-related genes jointly contribute to the risk of dental caries, supporting the role of genetic variants in the enamel-formation genes in the etiology of dental caries.

Anaerobic Test

Background: There are many athletes who like to listen to music while making a high intensity effort. However, research into the effects of listening to music on athletic performance has provided controversial results, and it is suggested that the timing and type of music might affect the anaerobic performance response. Purpose: The main aim of the current systematic review and meta-analysis was to analyze the effects while listening to music tasks via the 30 s Wingate anaerobic test (WAnT) on absolute performance and relative peak power (APP and RPP), absolute and relative mean power (AMP and RMP), and fatigue index (FI). Methods: PRISMA guidelines were used as a basis for conducting this systematic review, with inclusion criteria being set out according to the PICOS model. Computer-based literature research was undertaken until 10 March 2020 using the following online databases: PubMed/Medline, WOS, Cochrane Library, and Scopus. The literature was reviewed with regard to the effects of listening to music on the WAnT using several music variables on: APP, RPP, AMP, RMP and FI. Hedges’ g formula was used to calculate both standard mean differences and 95% confidence intervals, in order to establish continuous outcomes. Furthermore, the I2 statistic evaluated systematic differences (heterogeneity) together with a random effect meta-analysis model. Results: This systematic review included nine articles that researched into the effects of music on WAnT performance (six studies describe improvements in APP and/or RPP, four in AMP and/or RMP and three in FI). The random effects model was used to undertake a final meta-analysis, with standardized mean differences (SMD) and magnitude of standardized mean differences (MSMD) (Hedges’ g) being pooled accordingly. The resulting meta-analysis incorporated eight studies that had been previously published, with results showing that there were no apparent beneficial effects on APP (p = 0.09), AMP (p = 0.33) and FI (p = 0.46) as a consequence of listening to music. However, listening to music showed beneficial effects on RPP (SMD: 0.65; 95%: CI 0.35 to 0.96; MSMD: moderate; I2, 0%; p < 0.001) and RMP (SMD: 1.03; 95%: CI, 0.63 to 1.42; MSMD: trivial; I2, 0%; p < 0.001). Conclusion: This systematic review and meta-analysis has shown that listening to music during the WAnT might physiologically enhance relative anaerobic exercise performance, although reasons remain speculative.

Abstract Oesophagectomy is associated with high morbidity. One of the postoperative complication observed after esophageal resection is Post Operative Delirium (POD), a psychiatric disease caused by major surgical stress and pharmacological treatments. POD can jeopardize patient healing-process since patients are not collaborative to perioperative care but also because they can harm themselves. Thus the aim of this systematic review was to identify POD factors and its effective management in patients undergone oesophagectomy for oesophageal/oesophagogastric-junction cancer. Methods A comprehensive systematic literature search was conducted using PubMed, Cochrane Library, Scopus, psycINFO and psycARTICLES in order to identify all articles published until January 2020. The following combinations of terms were used for the search strategy: neoplasm; esophagus; gastro-esophageal junction; oesophagectomy; delirium. The following inclusion criteria were set: full article published in English; patients with esophageal cancer undergone oesophagectomy; POD observed. Two researchers independently selected studies matching the inclusion criteria. Duplicate studies, non-relevant topic, data from abstracts or unpublished were excluded. Any disagreements between the researchers’ evaluation concerning inclusion of studies were resolved by consensus. Results Of 235 studies yielded by systematic literature search, 21 met inclusion criteria. POD incidence was observed between 3 and 38% of patients and was precursor of other complications in 1/3 of POD patients. Preoperative risk factors were older age, cerebrovascular disease and pulmonary disfunction. Anxiety and depression resulted predisposing factors. Perioperative risk factors were duration of surgery, ICU length of stay, colloids infusion and blood transfusion. Open-surgery seemed to influence POD more than minimally-invasive and robotic surgery. Interventions identified to treat POD were pharmacological (prophylactic haloperidol, insomnia treatment) and behavioral (patient reorientation by family involvement, bright-light therapy, early mobilization). Conclusion This systematic review identified preoperative, intraoperative and postoperative risk factors of POD after oesophagectomy. No standardized prevention nor treatment of POD was identified. POD impacts patients’ ability in perceiving postoperative symptoms. The difficulty in communicating with health professionals may lead to delay the diagnosis of others complications and prolong hospital stay. Therefore further trials are required to assess efficacy of different POD treatments aimed to enhance postoperative management.

Pain Syndromes

Background: Post-stroke pain is one of the most common sequelae of stroke, which stands among the leading causes of death and adult-acquired disability worldwide. The role and clinical efficacy of opioids in post-stroke pain syndromes is still debated.Objectives: Due to the important gap in knowledge on the management of post-stroke pain, this systematic review aimed at assessing the efficacy of opioids in post-stroke pain syndromes.Methods: A literature search was conducted on databases relevant for medical scientific literature, i.e. PubMed/MEDLINE, Scopus, Web of Science and Cochrane Library databases from databases inception until August 31st, 2020 for clinical trials assessing the effects of opioids and opioid antagonists on pain reduction and pain related symptoms in patients with post-stroke pain syndromes. Studies assessing the effects of other medications (e.g., tricyclic antidepressant, pregabalin) or non - pharmacological management strategies (e.g., neurostimulation techniques) were excluded. The selected studies have been subjected to examination of the risk of bias.Results: The literature search retrieved 83,435 results. After duplicates removal, 34,285 articles were title and abstract screened. 25 full texts were assessed and 8 articles were identified to be eligible for inclusion in the qualitative summary and narrative analysis, of which three were placebo-controlled and two were dose-response. Among placebo-controlled studies, two evaluated the analgesic effect of morphine and one assessed the effects of the opioid antagonist naloxone on patients with central post-stroke pain. With regard to dose-response studies, both were on patients with central post-stroke pain, one assessing the efficacy of levorphanol, and the other on naloxone. Seven out of eight included studies showed an overall slight analgesic effect of opioids, with less consistent effects on other pain-related symptoms (e.g., mood, quality of life). The randomized controlled trials were subjected to meta-analysis and rating of the quality of evidence for the two outcomes considered according to GRADE (Grading of Recommendations, Assessment, Development and Evaluations) system. The overall results are inconclusive because of the small number of studies and of patients.Conclusions: The limited number of the included studies and their heterogeneity in terms of study design do not support the efficacy of opioids in post-stroke pain and in pain-related outcomes. Large double-blind randomized clinical trials with objective assessment of pain and related symptoms are needed to further investigate this topic.

Abstract BackgroundWe performed an updated systematic review and meta-analysis to compare the outcomes of CHA and UCHA in patients with FNFs.MethodsWe searched 6 English databases (Cochrane Library, ScienceDirect, PubMed, Embase, Medline, and Web of Science) and 4 Chinese databases (CNKI, VIP, Wang Fang, and Sino Med) in July 2020. The quality of each study was assessed according to the Cochrane handbook of systematic reviews. Data were pooled as risk ratios (RRs) and weighted mean differences (WMDs) with 95% confidence intervals (95% CIs). We used the random-effects model despite the heterogeneity among the studies. Data regarding baseline characteristics, hip function, complications both prosthetic-related and common, and operative outcomes are reported. ResultsA total of 24 RCTs based on 22 trials involving 3119 patients (CHA, 1575; UCHA, 1544) were included. Patients in CHA group show better hip function with HHS within 6 weeks (WMD=9.097, 95% CI, 3.034-15.161; P<0.003), 3 months (WMD=3.347, 95% CI, 1.478-5.216; P<0.001), 12 months (WMD=2.183, 95% CI, 0.161-4.205; P=0.034). The pooled results show that CHA had lower rates of refracture (RR=0.227, 95% CI, 0.135-0.381; P<0.0001), subsidence or loosening (RR=0.295, 95% CI, 0.112,0.778; P<0.014) and revision (RR=0.468, 95% CI, 0.279-0.786; P=0.004). Furthermore, CHA group tend to have lower pain(VAS score) (WMD=-0.568, 95% CI, -0.897 to -0.239; P=0.001), lower rate of pressure injury(RR=0.432, 95% CI, 0.221-0.846; P=0.014) and mortality at 1 year after surgery(RR=0.852, 95% CI, 0.727-0.998; P=0.047). UCHA showed a shorter operative duration(WMD=8.739, 95% CI, 6.354-11.124; P<0.0001).ConclusionsThis meta-analysis demonstrates that CHA has better hip function, lower rates of refracture, subsidence or loosening, revision, pressure ulcer, pain and one-year mortality than UCHA, while UCHA has shorter operative duration.

Purpose. Associations between XRCC1, XRCC3, and ERCC2 gene polymorphism and prognosis have been investigated in several cancers. The aim of this meta-analysis was to assess the prognostic value of XRCC1, XRCC3, and ERCC2 gene polymorphism in hepatocellular carcinoma (HCC). Methods. A systematic literature search was performed to identify relevant studies in PubMed, Embase, and the Cochrane library up to December 2018. The prognostic values of XRCC1, XRCC3, and ERCC2 polymorphisms in HCC were estimated using crude HRs with 95% CIs. Results. Ten studies involving 2687 patients were included in the quantitative analysis. There were no statistically significant associations between XRCC1 rs1799782 C>T, XRCC1 rs25487 G>A, and ERCC2 rs1799793 G>A polymorphisms and overall survival (OS). OS was significantly longer for the ERCC2 rs13181 CC genotype than for AA (CC vs. AA: HR = 0.33, 95% CI = 0.15–0.72). A significantly lower OS was observed for patients with the CT genotype compared with the CC genotype at XRCC3 rs861539 (CT vs. CC: HR = 1.64, 95% CI = 1.11–2.42). Conclusion. The ERCC2 rs13181 A>C polymorphism and XRCC3 rs861539 C>T polymorphism may be predictive markers for prognosis in patients with HCC. Well-designed studies with larger sample sizes are needed to verify our findings.

Objective: The aim of this systematic review and meta-analysis was to investigate whether or not the use of haloperidol could reduce the incidence of delirium in adult patients. Subjects and Methods: PubMed, Embase, the Cochrane Library, Elsevier, Wiley, and Ovid were searched for randomized controlled trials and prospective interventional cohort studies that compared haloperidol with placebo for delirium prophylaxis or with second generation antipsychotics for delirium treatment. The primary end point was the incidence and severity of delirium. After reviewing 272 relevant articles, 10 studies with 1,861 patients were finally included (haloperidol vs. placebo in 8 studies [n = 1,734], and haloperidol vs. second-generation antipsychotics in 2 studies [n = 127]). Revman 5.3 was used for the data analysis. Results: Compared with placebo, a high dose of prophylactic haloperidol (≥5 mg/day) may help reduce the incidence of delirium in surgical patients (risk ratio 0.50, 95% CI 0.32, 0.79). There were no differences in the duration of delirium, QTc interval prolongation, extrapyramidal symptoms, intensive care unit stay, hospital stay, or mortality between the haloperidol and placebo groups. For delirium treatment, haloperidol exhibited similar effects as the second-generation antipsychotics. Conclusions: In this study, the limited available data revealed that prophylaxis haloperidol at a dose of ≥5 mg/day might help reduce delirium in adult surgical patients. Further outcome studies with larger sample sizes are required to confirm these findings.
