AI brings gamechanging approaches for soccer analytics where soccer has been a typical benchmark for AI research. The combination has been an emerging topic. In this paper, soccer match analytics are taken as a complete observation-orientation-decision-action(OODA) loop.In addition, as in AI frameworks such as that for reinforcement learning, interacting with a virtual environment enables an evolving model. Therefore, both soccer analytics in the real world and virtual domains are discussed. With the intersection of the OODA loop and the real-virtual domains, available soccer data, including event and tracking data, and diverse orientation and decisionmaking models for both real-world and virtual soccer matches are comprehensively reviewed. Finally, some promising directions in this interdisciplinary area are pointed out. It is claimed that paradigms for both professional sports analytics and AI research could be combined. Moreover, it is quite promising to bridge the gap between the real and virtual domains for soccer match analysis and decision-making.展开更多

The odds ratio(OR) for all types of cancer was 1.79(1.56–2.05), and for individual cancers was 1.92(1.42–2.59) for lung cancer, 1.57(1.40–1.76) for breast cancer, 1.52(1.12–2.05) for bladder cancer, and 1.37(1.08–1.73) for liver cancer. The OR for circulatory system diseases was 1.92(1.29–2.85), with a value of 2.29(1.26–4.159) for stroke. The OR of respiratory system diseases was 1.76(1.13–2.74), with a value of 1.82(1.07–3.11) for childhood asthma. The original ORs were also shown for other diseases. Subgroup analyses were performed for lung and breast cancer. The ORs varied according to time period and were significant during exposure in the household;For lung cancer, the OR was significant in women.Conclusion The effect of SHS exposure in China was similar to that in Western countries, but its definition and characterization require further clarification. Studies on the association between SHS exposure and certain diseases with high incidence rates are insufficient.展开更多

Randomized controlled trials(RCTs) regarding the comparison of CHI-WM combination therapy and WM monotherapy were included. Literature search, risk-of-bias assessment, and data extraction were conducted by 2 reviewers independently. NMA was performed by Stata 14.0, R 4.0.4 software, and the latest risk of bias assessment tool 2(RoB 2).Results: A total of 53 RCTs were finally included, involving 4445 participants and 16 CHIs. RoB 2 showed that 2 of these studies had a high risk of bias. Tianqi injection(TQ) + WM was the most effective in reducing serum creatinine(Scr) level. Xingding injection(XD) + WM was the most effective in reducing blood urea nitrogen(BUN) and cystatin C(Cys C) levels. Guhong injection(GH) + WM had the highest endogenous creatinine clearance rate(Ccr). Shuxuetong injection(SXT) + WM was the most effective in improving the clinical effective rate. Danhong injection(DH) + WM resulted in the lowest 24-h urinary protein quantity(24 h-UPQ), while Danshen injection(DS) + WM led to the lowest blood uric acid(UA)level. Shenfu injection(SF) + WM was the most effective in increasing hemoglobin(Hb) level.Conclusion: CHIs-WM combination therapy is more effective than WM monotherapy in treating CRF.Considering all of the indicators, SK + WM may be the optimal treatment option for improving renal function in patients with CRF.展开更多

文摘BACKGROUND Hepatitis C virus(HCV)is a blood-borne virus which globally affects around 79 million people and is associated with high morbidity and mortality.Chronic infection leads to cirrhosis in a large proportion of patients and often causes hepatocellular carcinoma(HCC)in people with cirrhosis.Of the 6 HCV genotypes(G1-G6),genotype-3 accounts for 17.9%of infections.HCV genotype-3 responds least well to directly-acting antivirals and patients with genotype-3 infection are at increased risk of HCC even if they do not have cirrhosis.AIM To systematically review and critically appraise all risk factors for HCC secondary to HCV-G3 in all settings.Consequently,we studied possible risk factors for HCC due to HCV-G3 in the literature from 1946 to 2023.METHODS This systematic review aimed to synthesise existing and published studies of risk factors for HCC secondary to HCV genotype-3 and evaluate their strengths and limitations.We searched Web of Science,Medline,EMBASE,and CENTRAL for publications reporting risk factors for HCC due to HCV genotype-3 in all settings,1946-2023.RESULTS Four thousand one hundred and forty-four records were identified from the four databases with 260 records removed as duplicates.Three thousand eight hundred and eighty-four records were screened with 3514 excluded.Three hundred and seventy-one full-texts were assessed for eligibility with seven studies included for analysis.Of the seven studies,three studies were retrospective case-control trials,two retrospective cohort studies,one a prospective cohort study and one a cross-sectional study design.All were based in hospital settings with four in Pakistan,two in South Korea and one in the United States.The total number of participants were 9621 of which 167 developed HCC(1.7%).All seven studies found cirrhosis to be a risk factor for HCC secondary to HCV genotype-3 followed by higher age(five-studies),with two studies each showing male sex,high alpha feto-protein,directly-acting antivirals treatment and achievement of sustained virologic response as risk factors for developing HCC.CONCLUSION Although,studies have shown that HCV genotype-3 infection is an independent risk factor for end-stage liver disease,HCC,and liver-related death,there is a lack of evidence for specific risk factors for HCC secondary to HCV genotype-3.Only cirrhosis and age have demonstrated an association;however,the number of studies is very small,and more research is required to investigate risk factors for HCC secondary to HCV genotype-3.
文摘BACKGROUND Frailty is a common condition in elderly patients who receive percutaneous coronary intervention(PCI).However,how frailty affects clinical outcomes in this group is unclear.AIM To assess the link between frailty and the outcomes,such as in-hospital complic-ations,post-procedural complications,and mortality,in elderly patients post-PCI.METHODS The PubMed/MEDLINE,EMBASE,Cochrane Library,and Web of Science databases were screened for publications up to August 2023.The primary outcomes assessed were in-hospital and all-cause mortality,major adverse cardiovascular events(MACEs),and major bleeding.The Newcastle-Ottawa Scale was used for quality assessment.RESULTS Twenty-one studies with 739693 elderly patients undergoing PCI were included.Frailty was consistently associated with adverse outcomes.Frail patients had significantly higher risks of in-hospital mortality[risk ratio:3.45,95%confidence interval(95%CI):1.90-6.25],all-cause mortality[hazard ratio(HR):2.08,95%CI:1.78-2.43],MACEs(HR:2.92,95%CI:1.85-4.60),and major bleeding(HR:4.60,95%CI:2.89-7.32)compared to non-frail patients.CONCLUSION Frailty is a pivotal determinant in the prediction of risk of mortality,development of MACEs,and major bleeding in elderly individuals undergoing percutaneous coronary intervention.

文摘BACKGROUND Although the past decade has seen remarkable advances in treatment options for hepatocellular carcinoma(HCC),the dismal overall prognosis still envelops HCC patients.Several comparative trials have been conducted to study whether transarterial chemoembolization(TACE)could improve clinical outcomes in patients receiving sorafenib for advanced HCC;however,the findings have been inconsistent.AIM To study the potential synergies and safety of sorafenib plus TACE vs sorafenib alone for treating advanced HCC,by performing a systematic review and metaanalysis.METHODS This study was conducted following the PRISMA statement.A systematic literature search was conducted using the Cochrane Library,Embase,PubMed,and Web of Science databases.Data included in the present work were collected from patients diagnosed with advanced HCC receiving sorafenib plus TACE or sorafenib alone.Data synthesis and meta-analysis were conducted using Review Manager software.RESULTS The present study included 2780 patients from five comparative clinical trials(1 was randomized control trial and 4 were retrospective studies).It was found that patients receiving sorafenib plus TACE had better prognoses in terms of overall survival(OS),with a combined hazard ratio(HR)of 0.65[95%confidence interval(95%CI):0.46–0.93,P=0.02,n=2780].Consistently,progression free survival(PFS)and time to progression(TTP)differed significantly between the sorafenib plus TACE arm and sorafenib arm(PFS:HR=0.62,95%CI:0.40–0.96,P=0.03,n=443;TTP:HR=0.73,95%CI:0.64-0.83,P<0.00001,n=2451).Disease control rate(DCR)was also significantly increased by combination therapy(risk ratio=1.36,95%CI:1.02-1.81,P=0.04,n=641).Regarding safety,the incidence of any adverse event(AE)was increased due to the addition of TACE;however,no significant difference was found in grade≥3 AEs.CONCLUSION The combination of sorafenib with TACE has superior efficacy to sorafenib monotherapy,as evidenced by prolonged OS,PFS,and TTP,as well as increased DCR.Additional high-quality trials are essential to further validate the clinical benefit of this combination in the treatment of advanced HCC.
文摘BACKGROUND Polycystic kidney disease(PKD)is the most common genetic cause of kidney disease.It is a progressive and irreversible condition that can lead to end-stage renal disease and many other visceral complications.Current comprehensive data on PKD patterns in Africa is lacking.AIM To describe the prevalence and outcomes of PKD in the African population.METHODS A literature search of PubMed,African journal online,and Google Scholar databases between 2000 and 2023 was performed.The Preferred Reporting Items for Systematic Reviews and Meta-Analyses were followed to design the study.Clinical presentations and outcomes of patients were extracted from the included studies.RESULTS Out of 106 articles,we included 13 studies from 7 African countries.Ten of them were retrospective descriptive studies concerning 943 PKD patients with a mean age of 47.9 years.The accurate prevalence and incidence of PKD were not known but it represented the third causal nephropathy among dialysis patients.In majority of patients,the diagnosis of the disease was often delayed.Kidney function impairment,abdominal mass,and hypertension were the leading symptoms at presentation with a pooled prevalence of 72.1%(69.1-75.1),65.8%(62.2-69.4),and 57.4%(54.2-60.6)respectively.Hematuria and infections were the most frequent complications.Genotyping was performed in few studies that revealed a high proportion of new mutations mainly in the PKD1 gene.CONCLUSION The prevalence of PKD in African populations is not clearly defined.Clinical symptoms were almost present with most patients who had kidney function impairment and abdominal mass at the diagnostic.Larger studies including genetic testing are needed to determine the burden of PKD in African populations.
文摘Objective:Many strategic efforts were made to address nurses'shortage in controlling Coronavirus disease 2019(COVID-19),including recruiting student health volunteers.This review aimed to explore the contribution and involvement of nursing student volunteers during COVID-19.Methods:A systematic review was registered in PROSPERO International CRD42021283069.Electronic databases for ar ticle search included:SCOPUS,EBSCO MEDLINE,Pub Med,Pro Quest,Springer,Sage Pub,and hand searching.The critical appraisal study quality using The Joanna Briggs Institutes.Data extraction and synthesis used Population,Intervention,Comparison,Outcome,and Design(PICO and D)framework with thematic analysis.Results:Twelve studies were enrolled from 2545 retrieved,with 4 synthesized themes:(1)determinant of the involvement of nursing student volunteers during COVID-19,which includes 3 subthemes:motivations,perception,and barriers,(2)expectations and actual condition of nursing students as volunteers,(3)the need for nursing student volunteers,and(4)the impact and level of student volunteers'contribution.All student volunteers contribute to providing direct or indirect services to patients.Conclusions:This review provides an overview of nursing student volunteers'needs useful in developing competency frameworks and the role of culturally sensitive volunteers in education and training.In the future,student volunteers could choose the appropriate volunteer program and location according to their competence.
文摘BACKGROUND Virtual reality(VR)has emerged as an innovative technology in endoscopy training,providing a simulated environment that closely resembles real-life scenarios and offering trainees a valuable platform to acquire and enhance their endoscopic skills.This systematic review will critically evaluate the effectiveness and feasibility of VR-based training compared to traditional methods.AIM To evaluate the effectiveness and feasibility of VR-based training compared to traditional methods.By examining the current state of the field,this review seeks to identify gaps,challenges,and opportunities for further research and implementation of VR in endoscopic training.METHODS The study is a systematic review,following the guidelines for reporting systematic reviews set out by the PRISMA statement.A comprehensive search command was designed and implemented and run in September 2023 to identify relevant studies available,from electronic databases such as PubMed,Scopus,Cochrane,and Google Scholar.The results were systematically reviewed.RESULTS Sixteen articles were included in the final analysis.The total number of participants was 523.Five studies focused on both upper endoscopy and colonoscopy training,two on upper endoscopy training only,eight on colonoscopy training only,and one on sigmoidoscopy training only.Gastrointestinal Mentor virtual endoscopy simulator was commonly used.Fifteen reported positive results,indicating that VR-based training was feasible and acceptable for endoscopy learners.VR technology helped the trainees enhance their skills in manipulating the endoscope,reducing the procedure time or increasing the technical accuracy,in VR scenarios and real patients.Some studies show that the patient discomfort level decreased significantly.However,some studies show there were no significant differences in patient discomfort and pain scores between VR group and other groups.CONCLUSION VR training is effective for endoscopy training.There are several well-designed randomized controlled trials with large sample sizes,proving the potential of this innovative tool.Thus,VR should be more widely adopted in endoscopy training.Furthermore,combining VR training with conventional methods could be a promising approach that should be implemented in training.

文摘Due to ever-growing soccer data collection approaches and progressing artificial intelligence(AI) methods, soccer analysis, evaluation, and decision-making have received increasing interest from not only the professional sports analytics realm but also the academic AI research community. AI brings gamechanging approaches for soccer analytics where soccer has been a typical benchmark for AI research. The combination has been an emerging topic. In this paper, soccer match analytics are taken as a complete observation-orientation-decision-action(OODA) loop.In addition, as in AI frameworks such as that for reinforcement learning, interacting with a virtual environment enables an evolving model. Therefore, both soccer analytics in the real world and virtual domains are discussed. With the intersection of the OODA loop and the real-virtual domains, available soccer data, including event and tracking data, and diverse orientation and decisionmaking models for both real-world and virtual soccer matches are comprehensively reviewed. Finally, some promising directions in this interdisciplinary area are pointed out. It is claimed that paradigms for both professional sports analytics and AI research could be combined. Moreover, it is quite promising to bridge the gap between the real and virtual domains for soccer match analysis and decision-making.

文摘Objective To analyze the association between exposure to second-hand smoke(SHS) and 23 diseases,categorized into four classifications, among the Chinese population.Methods We searched the literature up to June 30, 2021, and eligible studies were identified according to the PECOS format: Participants and Competitors(Chinese population), Exposure(SHS),Outcomes(Disease or Death), and Study design(Case-control or Cohort).Results In total, 53 studies were selected. The odds ratio(OR) for all types of cancer was 1.79(1.56–2.05), and for individual cancers was 1.92(1.42–2.59) for lung cancer, 1.57(1.40–1.76) for breast cancer, 1.52(1.12–2.05) for bladder cancer, and 1.37(1.08–1.73) for liver cancer. The OR for circulatory system diseases was 1.92(1.29–2.85), with a value of 2.29(1.26–4.159) for stroke. The OR of respiratory system diseases was 1.76(1.13–2.74), with a value of 1.82(1.07–3.11) for childhood asthma. The original ORs were also shown for other diseases. Subgroup analyses were performed for lung and breast cancer. The ORs varied according to time period and were significant during exposure in the household;For lung cancer, the OR was significant in women.Conclusion The effect of SHS exposure in China was similar to that in Western countries, but its definition and characterization require further clarification. Studies on the association between SHS exposure and certain diseases with high incidence rates are insufficient.
文摘BACKGROUND Irritable bowel syndrome(IBS)is the most prevalent gastrointestinal disorder in developed countries and reduces patients’quality of life,hinders their ability to work,and increases health care costs.A growing number of trials have demonstrated an aberrant gut microbiota composition in IBS,also known as‘gut dysbiosis’.Fecal microbiota transplantation(FMT)has been suggested as a treatment for IBS.AIM To assess the efficacy and safety of FMT for the treatment of IBS.METHODS We searched Cochrane Central,MEDLINE,EMBASE and Web of Science up to 24 October 2022 for randomised controlled trials(RCTs)investigating the effectiveness of FMT compared to placebo(including autologous FMT)in treating IBS.The primary outcome was the number of patients with improvements of symptoms measured using a validated,global IBS symptoms score.Secondary outcomes were changes in quality-of-life scores,non-serious and serious adverse events.Risk ratios(RR)and corresponding 95%CI were calculated for dichotomous outcomes,as were the mean differences(MD)and 95%CI for continuous outcomes.The Cochrane risk of bias tool was used to assess the quality of the trials.GRADE criteria were used to assess the overall quality of the evidence.RESULTS Eight RCTs(484 participants)were included in the review.FMT resulted in no significant benefit in IBS symptoms three months after treatment compared to placebo(RR 1.19,95%CI:0.68-2.10).Adverse events were reported in 97 participants in the FMT group and in 45 participants in the placebo group(RR 1.17,95%CI:0.63-2.15).One serious adverse event occurred in the FMT group and two in the placebo group(RR 0.42,95%CI:0.07-2.60).Endoscopic FMT delivery resulted in a significant improvement in symptoms,while capsules did not.FMT did not improve the quality of life of IBS patients but,instead,appeared to reduce it,albeit non significantly(MD-6.30,95%CI:-13.39-0.79).The overall quality of the evidence was low due to moderate-high inconsistency,the small number of patients in the studies,and imprecision.CONCLUSION We found insufficient evidence to support or refute the use of FMT for IBS.Larger trials are needed.

文摘Objective: To conduct a systematic review and network meta-analysis(NMA) for the comparison of the efficacy and safety of Chinese herbal injection(CHI) combined with Western medicine(WM) and WM monotherapy for chronic renal failure(CRF).Methods: Eight databases were searched from inception to August 30, 2022. Randomized controlled trials(RCTs) regarding the comparison of CHI-WM combination therapy and WM monotherapy were included. Literature search, risk-of-bias assessment, and data extraction were conducted by 2 reviewers independently. NMA was performed by Stata 14.0, R 4.0.4 software, and the latest risk of bias assessment tool 2(RoB 2).Results: A total of 53 RCTs were finally included, involving 4445 participants and 16 CHIs. RoB 2 showed that 2 of these studies had a high risk of bias. Tianqi injection(TQ) + WM was the most effective in reducing serum creatinine(Scr) level. Xingding injection(XD) + WM was the most effective in reducing blood urea nitrogen(BUN) and cystatin C(Cys C) levels. Guhong injection(GH) + WM had the highest endogenous creatinine clearance rate(Ccr). Shuxuetong injection(SXT) + WM was the most effective in improving the clinical effective rate. Danhong injection(DH) + WM resulted in the lowest 24-h urinary protein quantity(24 h-UPQ), while Danshen injection(DS) + WM led to the lowest blood uric acid(UA)level. Shenfu injection(SF) + WM was the most effective in increasing hemoglobin(Hb) level.Conclusion: CHIs-WM combination therapy is more effective than WM monotherapy in treating CRF.Considering all of the indicators, SK + WM may be the optimal treatment option for improving renal function in patients with CRF.

文摘BACKGROUND Pancreatic cancer is difficult to be diagnosed early clinically,while often leads to poor prognosis.If optimal personalized treatment plan can be provided to pancreatic cancer patient at an earlier stage,this can greatly improve overall survival(OS).Circulating tumor cells(CTCs)are a collective term for various types of tumor cells present in the peripheral blood(PB),which are formed by detachment during the development of solid tumor lesions.Most CTCs undergo apoptosis or are phagocytosed after entering the PB,whereas a few can escape and anchor at distal sites to develop metastasis,increasing the risk of death for patients with malignant tumors.AIM To investigate the significance of CTCs in predicting the prognosis of early pancreatic cancer patients.METHODS The PubMed,EMBASE,Web of Science,Cochrane Library,China National Knowledge Infrastructure,China Biology Medicine,and ChinaInfo databases were searched for articles published through December 2022.Studies were considered qualified if they included patients with early pancreatic cancer,analyzed the prognostic value of CTCs,and were full papers reported in English or Chinese.Researches were selected and assessed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol and the Newcastle-Ottawa Scale criteria.We used a funnel plot to assess publication bias.RESULTS From 1595 publications,we identified eight eligible studies that collectively enrolled 355 patients with pancreatic cancer.Among these original studies,two were carried out in China;three in the United States;and one each in Italy,Spain,and Norway.All eight studies analyzed the relevance between CTCs and the prognosis of patients with early-stage pancreatic cancer after surgery.A meta-analysis showed that the patients that were positive pre-treatment or post-treatment for CTCs were associated with decreased OS[hazard ratio(HR)=1.93,95% confidence interval(CI):1.197-3.126,P=0.007]and decreased relapse-free/disease-free/progressionfree survival(HR=1.27,95%CI:1.137-1.419,P<0.001)in early-stage pancreatic cancer.Additionally,the results suggest no statistically noticeable publication bias for overall,disease-free,progression-free,and recurrence-free survival.CONCLUSION This pooled meta-analysis shows that CTCs,as biomarkers,can afford reliable prognostic information for patients with early-stage pancreatic cancer and help develop individualized treatment plans.

文摘Currently,there is no cure for traumatic spinal co rd injury but one therapeutic approach showing promise is gene therapy.In this systematic review and meta-analysis,we aim to assess the efficacy of gene therapies in pre-clinical models of spinal cord injury and the risk of bias.In this metaanalysis,registe red at PROSPERO(Registration ID:CRD42020185008),we identified relevant controlled in vivo studies published in English by searching the PubMed,Web of Science,and Embase databases.No restrictions of the year of publication were applied and the last literature search was conducted on August 3,2020.We then conducted a random-effects meta-analysis using the restricted maximum likelihood estimator.A total of 71 studies met our inclusion crite ria and were included in the systematic review.Our results showed that overall,gene therapies were associated with improvements in locomotor score(standardized mean difference[SMD]:2.07,95%confidence interval[CI]:1.68-2.47,Tau^(2)=2.13,I^(2)=83.6%)and axonal regrowth(SMD:2.78,95%CI:1.92-3.65,Tau^(2)=4.13,I^(2)=85.5%).There was significant asymmetry in the funnel plots of both outcome measures indicating the presence of publication bias.We used a modified CAMARADES(Collaborative Approach to M eta-Analysis and Review of Animal Data in Experimental Studies)checklist to assess the risk of bias,finding that the median score was 4(IQR:3-5).In particula r,reports of allocation concealment and sample size calculations were lacking.In conclusion,gene therapies are showing promise as therapies for spinal co rd injury repair,but there is no consensus on which gene or genes should be targeted.
文摘Objective No consensus exists on the relative risk(RR)of lung cancer(LC)attributable to active smoking in China.This study aimed to evaluate the unified RR of LC attributable to active smoking among the Chinese population.Methods A systematic literature search of seven databases was conducted to identify studies reporting active smoking among smokers versus nonsmokers in China.Primary articles on LC providing risk estimates with their 95%confidence intervals(CIs)for“ever”“former”or“current”smokers from China were selected.Meta-analysis was used to estimate the pooled RR of active smoking.Results Forty-four unique studies were included.Compared with that of nonsmokers,the pooled RR(95%CI)for“ever”“former”and“current”smokers were 3.26(2.79–3.82),2.95(1.71–5.08),and 5.16(2.58–10.34)among men,3.18(2.78–3.63),2.70(2.08–3.51),and 4.27(3.61–5.06)among women,and2.71(2.12–3.46),2.66(2.45–2.88),and 4.21(3.25–5.45)in both sexes combined,respectively.Conclusion The RR of LC has remained relatively stable(range,2–6)over the past four decades in China.Early quitting of smoking could reduce the RR to some extent;however,completely refraining from smoking is the best way to avoid its adverse effects.
