2Multimorbidity patterns and association with mortality in 0.5 million Chinese adults显示文摘Background:Few studies have assessed the relationship between multimorbidity patterns and mortality risk in the Chinese population.We aimed to identify multimorbidity patterns and examined the associations of multimorbidity patterns and the number of chronic diseases with the risk of mortality among Chinese middle-aged and older adults.Methods:We used data from the China Kadoorie Biobank and included 512,723 participants aged 30 to 79 years.Multimorbidity was defined as the presence of two or more of the 15 chronic diseases collected by self-report or physical examination at baseline.Multimorbidity patterns were identified using hierarchical cluster analysis.Cox regression was used to estimate the associations of multimorbidity patterns and the number of chronic diseases with all-cause and cause-specific mortality.Results:Overall,15.8%of participants had multimorbidity.The prevalence of multimorbidity increased with age and was higher in urban than rural participants.Four multimorbidity patterns were identified,including cardiometabolic multimorbidity(diabetes,coronary heart disease,stroke,and hypertension),respiratory multimorbidity(tuberculosis,asthma,and chronic obstructive pulmonary disease),gastrointestinal and hepatorenal multimorbidity(gallstone disease,chronic kidney disease,cirrhosis,peptic ulcer,and cancer),and mental and arthritis multimorbidity(neurasthenia,psychiatric disorder,and rheumatoid arthritis).During a median of 10.8 years of follow-up,49,371 deaths occurred.Compared with participants without multimorbidity,cardiometabolic multimorbidity(hazard ratios[HR]=2.20,95%confidence intervals[CI]:2.14-2.26)and respiratory multimorbidity(HR=2.13,95%CI:1.97-2.31)demonstrated relatively higher risks of mortality,followed by gastrointestinal and hepatorenal multimorbidity(HR=1.33,95%CI:1.22-1.46).The mortality risk increased by 36%(HR=1.36,95%CI:1.35-1.37)with every additional disease.Conclusion:Cardiometabolic multimorbidity and respiratory multimorbidity posed the highest threat on mortality risk and deserved particular attention in Chinese adults.Junning Fan Zhijia Sun Canqing Yu Yu Guo Pei Pei Ling Yang Yiping Chen Huaidong Du Dianjianyi Sun Yuanjie Pang Jun Zhang Simon Gilbert Daniel Avery Junshi Chen Zhengming Chen Jun Lyu Liming Li On Behalf of the China Kadoorie Biobank Collaborative Group 2022Chinese Medical Journal2022,,6:17
3Minimally invasive surgery for gastric cancer: A comparison between robotic, laparoscopic and open surgery显示文摘AIM To investigate the role of minimally invasive surgery for gastric cancer and determine surgical, clinical, and oncological outcomes.METHODS This is a propensity score-matched case-control study, comparing three treatment arms: robotic gastrectomy(RG), laparoscopic gastrectomy(LG), open gastrectomy(OG). Data collection started after sharing a specific study protocol. Data were recorded through a tailored and protected web-based system. Primary outcomes: harvested lymph nodes, estimated blood loss, hospital stay, complications rate. Among the secondary outcomes, there are: operative time, R0 resections, POD of mobilization, POD of starting liquid diet and soft solid diet. The analysis includes the evaluation of type and grade of postoperative complications. Detailed information of anastomotic leakages is also provided.RESULTS The present analysis was carried out of 1026 gastrectomies. To guarantee homogenous distribution of cases, patients in the RG, LG and OG groups were 1:1:2 matched using a propensity score analysis with a caliper = 0.2. The successful matching resulted in a total sample of 604 patients(RG = 151; LG = 151; OG = 302). The three groups showed no differences in all baseline patients characteristics, type of surgery(P = 0.42) and stage of the disease(P = 0.16). Intraoperative blood loss was significantly lower in the LG(95.93 ± 119.22) and RG(117.91 ± 68.11) groups compared to the OG(127.26 ± 79.50, P = 0.002). The mean number of retrieved lymph nodes was similar between the RG(27.78 ± 11.45), LG(24.58 ± 13.56) and OG(25.82 ± 12.07) approach. A benefit in favor of the minimally invasive approaches was found in the length of hospital stay(P < 0.0001). A similar complications rate was found(P = 0.13). The leakage rate was not different(P = 0.78) between groups.CONCLUSION Laparoscopic and robotic surgery can be safely performed and proposed as possible alternative to open surgery. The main highlighted benefit is a faster postoperative functional recovery.Amilcare Parisi Daniel Reim Felice Borghi Ninh T Nguyen Feng Qi Andrea Coratti Fabio Cianchi Maurizio Cesari Francesca Bazzocchi Orhan Alimoglu Johan Gagnière Graziano Pernazza Simone D'Imporzano Yan-Bing Zhou Juan-Santiago Azagra Olivier Facy Steven T Brower Zhi-Wei Jiang Lu Zang Arda Isik Alessandro Gemini Stefano Trastulli Alexander Novotny Alessandra Marano Tong Liu Mario Annecchiarico Benedetta Badii Giacomo Arcuri Andrea Avanzolini Metin Leblebici Denis Pezet Shou-Gen Cao Martine Goergen Shu Zhang Giorgio Palazzini Vito D'Andrea Jacopo Desiderio 2017World Journal of Gastroenterology2017,23,13:17
4The role of the androgen receptor in prostate development and benign prostatic hyperplasia:A review显示文摘Benign prostatic hyperplasia(BPH)is a benign enlargement of the prostate in which incidence increases linearly with age,beginning at about 50 years old.BPH is a significant source of morbidity in aging men by causing lower urinary tract symptoms and acute urinary retention.Unfortunately,the etiology of BPH incidence and progression is not clear.This review highlights the role of the androgen receptor(AR)in prostate development and the evidence for its involvement in BPH.The AR is essential for normal prostate development,and individuals with defective AR signaling,such as after castration,do not experience prostate enlargement with age.Furthermore,decreasing dihydrotestosterone availability through therapeutic targeting with 5a-reductase inhibitors diminishes AR activity and results in reduced prostate size and symptoms in some BPH patients.While there is some evidence that AR expression is elevated in certain cellular compartments,how exactly AR is involved in BPH progression has yet to be elucidated.It is possible that AR signaling within stromal cells alters intercellular signaling and a“reawakening”of the embryonic mesenchyme,loss of epithelial AR leads to changes in paracrine signaling interactions,and/or chronic inflammation aids in stromal or epithelial proliferation evident in BPH.Unfortunately,a subset of patients fails to respond to current medical approaches,forcing surgical treatment even though age or associated co-morbidities make surgery less attractive.Fundamentally,new therapeutic approaches to treat BPH are not currently forthcoming,so a more complete molecular understanding of BPH etiology is necessary to identify new treatment options.Renee E.Vickman Omar E.Franco Daniel C.Moline Donald J.Vander Griend Praveen Thumbikat Simon W.Hayward 2020Asian Journal of Urology2020,7,3:11
5Stem cell treatment and cerebral palsy: Systemic review and meta-analysis显示文摘BACKGROUND Perinatal complications may result in life-long morbidities,among which cerebral palsy(CP)is the most severe motor disability.Once developed,CP is a nonprogressive disease with a prevalence of 1-2 per 1000 live births in developed countries.It demands an extensive and multidisciplinary care.Therefore,it is a challenge for our health system and a burden for patients and their families.Recently,stem cell therapy emerged as a promising treatment option and raised hope in patients and their families.AIM The aim is to evaluate the efficacy and safety of stem cell treatment in children with CP using a systematic review and meta-analysis METHODS We performed a systematic literature search on PubMed and EMBASE to find randomized controlled clinical trials(RCT)investigating the effect of stem cell transplantation in children with CP.After the review,we performed a randomeffects meta-analysis focusing on the change in gross motor function,which was quantified using the gross motor function measure.We calculated the pooled standardized mean differences of the 6-and/or 12-mo-outcome by the method of Cohen.We quantified the heterogeneity using the I-squared measure.RESULTS We identified a total of 8 RCT for a qualitative review.From the initially selected trials,5 met the criteria and were included in the meta-analysis.Patients’population ranged from 0.5 up to 35 years(n=282).We detected a significant improvement in the gross motor function with a pooled standard mean difference of 0.95(95%confidence interval:0.13-1.76)favoring the stem cell group and a high heterogeneity(I2=90.1%).Serious adverse events were rare and equally distributed among both intervention and control groups.CONCLUSION Stem cell therapy for CP compared with symptomatic standard care only,shows a significant positive effect on the gross motor function,although the magnitude of the improvement is limited.Short-term safety is present and further highquality RCTs are needed.Simone Eggenberger Céline Boucard Andreina Schoeberlein Raphael Guzman Andreas Limacher Daniel Surbek Martin Mueller 2019World Journal of Stem Cells2019,11,10:8
6Strategies to optimize the use of marginal donors in liver transplantation显示文摘Liver transplantation is the treatment of choice for end stage liver disease, but availability of liver grafts is still the main limitation to its wider use. Extended criteria donors(ECD) are considered not ideal for several reasons but their use has dramatically grown in the last decades in order to augment the donor liver pool. Due to improvement in surgical and medical strategies, results using grafts from these donors have become acceptable in terms of survival and complications; nevertheless a big debate still exists regarding their selection, discharge criteria and allocation policies. Many studies analyzed the use of these grafts from many points of view producing different or contradictory results so that accepted guidelines do not exist and the use of these grafts is still related to non-standardized policies changing from center to center. The aim of this review is to analyze every step of the donationtransplantation process emphasizing all those strategies, both clinical and experimental, that can optimize results using ECD.Daniele Pezzati Davide Ghinolfi Paolo De Simone Emanuele Balzano Franco Filipponi 2015World Journal of Hepatology2015,7,26:8

9Towards maximized utilization of iridium for the acidic oxygen evolution reaction显示文摘The reduction in noble metal content for efficient oxygen evolution catalysis is a crucial aspect towards the large scale commercialisation of polymer electrolyte membrane electrolyzers.Since catalytic stability and activity are inversely related,long service lifetime still demands large amounts of low-abundant and expensive iridium.In this manuscript we elaborate on the concept of maximizing the utilisation of iridium for the oxygen evolution reaction.By combining different tin oxide based support materials with liquid atomic layer deposition of iridium oxide,new possibilities are opened up to grow thin layers of iridium oxide with tuneable noble metal amounts.In-situ,time-and potential-resolved dissolution experiments reveal how the stability of the substrate and the catalyst layer thickness directly affect the activity and stability of deposited iridium oxide.Based on our results,we elaborate on strategies how to obtain stable and active catalysts with maximized iridium utilisation for the oxygen evolution reaction and demonstrate how the activity and durability can be tailored correspondingly.Our results highlight the potential of utilizing thin noble metal films with earth abundant support.materials for future catalytic applications in the energy sector.Marc Ledendecker Simon Geiger Katharina Hengge Joohyun Lim Serhiy Cherevko Andrea M.

10pRB expression in esophageal mucosa of individuals at high risk for squamous cell carcinoma of the esophagus显示文摘AIM: To investigate the pRb expression in a large group of patients with history of chronic exposure to the main risk factors for development of squamous cell carcinoma of the esophagus. METHODS: One hundred and seventy asymptomatic individuals at high risk for esophageal squamous cell carcinoma (consumption of more than 80 g of ethanol and 10 cigarettes/d for at least 10 years) underwent upper gastrointestinal endoscopy with biopsies of the esophageal mucosa. As a control group, specimens of esophageal mucosa obtained from 20 healthy subjects were also studied. Immunohistochemical assessment of the tissues was performed using a monoclonal antibody anti-pRB protein. RESULTS: Absence of the pRB staining, indicating loss of RB function, was observed in 33 (19.4%) of the individuals at risk for esophageal cancer, but in none of the healthy controls (P < 0.02). Loss of pRb expression increased in a stepwise fashion according to the severity of the histological findings (P < 0.005): normal mucosa (11/97 or 11.3%), chronic esophagitis (17/60 or 28.3%), low-grade dysplasia (3/10 or 30%), high-grade dysplasia 1/2 or 50%) and squamous cell carcinoma (1/1 or 100%). CONCLUSION: Our findings suggest that abnormal expression of the pRB protein may be implicated in the process of esophageal carcinogenesis. Additional studies are warranted to define the role of the pRBprotein as a biomarker for development of esophageal squamous cell carcinoma in individuals at high risk for this malignancy.Simone S Contu Paulo C Contu Daniel C Damin Renato B Fagundes Fabiano Bevilacqua Aline S Rosa Joo C Prolla Luis F Moreira 2007World Journal of Gastroenterology2007,13,11:5
11An Exploration of Deep-Learning Based Phenotypic Analysis to Detect Spike Regions in Field Conditions for UK Bread Wheat显示文摘Wheat is one of the major crops in the world,with a global demand expected to reach 850 million tons by 2050 that is clearly outpacing current supply.The continual pressure to sustain wheat yield due to the world’s growing population under fluctuating climate conditions requires breeders to increase yield and yield stability across environments.We are working to integrate deep learning into field-based phenotypic analysis to assist breeders in this endeavour.We have utilised wheat images collected by distributed CropQuant phenotyping workstations deployed for multiyear field experiments of UK bread wheat varieties.Based on these image series,we have developed a deep-learning based analysis pipeline to segment spike regions from complicated backgrounds.As a first step towards robust measurement of key yield traits in the field,we present a promising approach that employ Fully Convolutional Network(FCN)to performsemantic segmentation of images to segment wheat spike regions.We also demonstrate the benefits of transfer learning through the use of parameters obtained from other image datasets.We found that the FCN architecture had achieved a Mean classification Accuracy(MA)>82%on validation data and>76%on test data and Mean Intersection over Union value(MIoU)>73%on validation data and and>64%on test datasets.Through this phenomics research,we trust our attempt is likely to form a sound foundation for extracting key yield-related traits such as spikes per unit area and spikelet number per spike,which can be used to assist yield-focused wheat breeding objectives in near future.Tahani Alkhudaydi Daniel Reynolds Simon Griffiths Ji Zhou Beatriz de la Iglesia 2019Plant Phenomics2019,1,1:5
12Clinical applications of feature-tracking cardiac magnetic resonance imaging显示文摘Cardiovascular diseases represent the leading cause of mortality and morbidity in the western world. Assessment of cardiac function is pivotal for early diag-nosis of primitive myocardial disorders, identification of cardiac involvement in systemic diseases, detection of drug-related cardiac toxicity as well as risk stratification and monitor of treatment effects in patients with heart failure of various etiology. Determination of ejection fraction with different imaging modalities currently represents the gold standard for evaluation of cardiac function. However, in the last few years, cardiovascular magnetic resonance feature tracking techniques has emerged as a more accurate tool for quantitative evalu-ation of cardiovascular function with several parameters including strain, strain-rate, torsion and mechanical dispersion. This imaging modality allows precise quantification of ventricular and atrial mechanics by directly evaluating myocardial fiber deformation. The purpose of this article is to review the basic principles, current clinical applications and future perspectives of cardiovascular magnetic resonance myocardial feature tracking, highlighting its prognostic implications.Daniele Muser Simon A Castro Pasquale Santangeli Gaetano Nucifora 2018World Journal of Cardiology2018,10,11:4

14Outcome analysis of management of liver trauma: A 10-year experience at a trauma center显示文摘AIM: To review the outcomes of liver trauma in patients with hepatic injuries only and in patients with associated injuries outside the liver.METHODS: Data of liver trauma patients presented to our center from January 2003 to October 2013 were reviewed. The patients were divided into two groups. Group 1 consisted of patients who had hepatic injuries only. Group 2 consisted of patients who also had associated injuries outside the liver.RESULTS: Seven(30.4%) patients in group 1 and 10(28.6%) patients in group 2 received non-operative management; the rest underwent operation. Blunt trauma occurred in 82.8%(48/58) of the patients and penetrative trauma in 17.2%(10/58). A higher injury severity score(ISS) was observed in group 2(median 45 vs 25, P < 0.0001). More patients in group 1 were hemodynamically stable(65.2% vs 37.1%, P = 0.036). Other parameters were comparable between groups. Group 1 had better 30-d survival(91.3% vs 71.4%, P = 0.045). On multivariate analysis using the logistic regression model, ISS was found to be associated with mortality(P = 0.004, hazard ratio = 1.035, 95%CI:CONCLUSION: Liver trauma patients with multiple injuries are relatively unstable on presentation. Despite a higher ISS in group 2, non-operative management was possible for selected patients. Associated injuries outside the liver usually account for morbidity and mortality.Wong Hoi She Tan To Cheung Wing Chiu Dai Simon HY Tsang Albert CY Chan Daniel KH Tong Gilberto KK Leung Chung Mau Lo 2016World Journal of Hepatology2016,8,15:3
15Update on pathogenesis and predictors of response of therapeutic strategies used in inflammatory bowel disease显示文摘The search for biomarkers that characterize specific aspects of inflammatory bowel disease(IBD), has received substantial interest in the past years and is moving forward rapidly with the help of modern technologies. Nevertheless, there is a direct demand to identify adequate biomarkers for predicting and evaluating therapeutic response to different therapies. In this subset, pharmacogenetics deserves more attention as part of the endeavor to provide personalized medicine. The ultimate goal in this area is the adjustment of medication for a patient's specific genetic background and thereby to improve drug efficacy and safety rates. The aim of the following review is to utilize the latest knowledge on immunopathogenesis of IBD and update the findings on the field of Immunology and Genetics, to evaluate the response to the different therapies. In the present article, more than 400 publications were reviewed but finally 287 included based on design, reproducibility(or expectancy to be reproducible and translationable into humans) or already measured in humans. A few testshave shown clinical applicability. Other, i.e., genetic associations for the different therapies in IBD have not yet shown consistent or robust results. In the close future it is anticipated that this, cellular and genetic material, as well as the determination of biomarkers will be implemented in an integrated molecular diagnostic and prognostic approach to manage IBD patients.Emilio G Quetglas Zlatan Mujagic Simone Wigge Daniel Keszthelyi Sebastian Wachten Ad Masclee Walter Reinisch 2015World Journal of Gastroenterology2015,21,44:3
16Recurrence in node-negative advanced gastric cancer:Novel findings from an in-depth pathological analysis of prognostic factors from a multicentric series显示文摘AIM To analyze the clinicopathological characteristics of patients with both node-negative gastric carcinoma and diagnosis of recurrence during follow-up. METHODS We enrolled 41 patients treated with curative gastrectomy for p T2-4 a N0 gastric carcinoma between 1992 and 2010,who developed recurrence(Group 1). We retrospectively selected this group from the prospectively collected database of 4 centers belonging to the Italian Research Group for Gastric Cancer,and compared them with 437 p T2-4 a N0 patients without recurrence(Group 2). We analyzed lymphatic embolization,microvascular infiltration,perineural infiltration,and immunohistochemical determination of p53,Ki67,and HER2 in Group 1 and in a subgroup of Group 2(Group 2 bis) of 41 cases matched with Group 1 according to demographic and pathological characteristics. RESULTS T4 a stage and diffuse histotype were associated with recurrence in the group of p N0 patients. In-depth pathological analysis of two homogenous groups of p N0 patients,with and without recurrence during longterm follow-up(groups 1 and 2 bis),revealed two striking patterns: lymphatic embolization and perineural infiltration(two parameters that pathologists can easily report),and p53 and Ki67,represent significant factors for recurrence.CONCLUSION The reported pathological features should be considered predictive factors for recurrence and could be useful to stratify node-negative gastric cancer patients for adjuvant treatment and tailored follow-up.Gian Luca Baiocchi Sarah Molfino Carla Baronchelli Simone Giacopuzzi Daniele Marrelli Paolo Morgagni Maria Bencivenga Luca Saragoni Carla Vindigni Nazario Portolani Maristella Botticini Giovanni De Manzoni 2017World Journal of Gastroenterology2017,23,45:3
