| 1 | Umbilical cord as a mesenchymal stem cell source for treating joint pathologies显示文摘Articular cartilage disorders and injuries often result in life-long chronic pain and compromised quality of life.Regrettably,the regeneration of articular cartilage is a continuing challenge for biomedical research.One of the most promising therapeutic approaches is cellbased tissue engineering,which provides a healthy population of cells to the injured site but requires differentiated chondrocytes from an uninjured site.The use of healthy chondrocytes has been found to have limitations.A promising alternative cell population is mesenchymal stem cells(MSCs),known to possess excellent proliferation potential and proven capability for differentiation into chondrocytes.The“immunosuppressive”property of human MSCs makes them an important candidate for allogeneic cell therapy.The use of allogeneic MSCs to repair large defects may prove to be an alternative to current autologous and allogeneic tissue-grafting procedures.An allogeneic cell-based approach would enable MSCs to be isolated from any donor,expanded and cryopreserved in allogeneic MSC banks,providing a readily available source of progenitors for cell replacement therapy.These possibilities have spawned the current exponential growth in stem cell research in pharmaceutical and biotechnology communities.Our objective in this review is to summarize the knowledge about MSCs from umbilical cord stroma and focus mainly on their applications for joint pathologies. | María Carmen Arufe Alexandre De la Fuente Isaac Fuentes Francisco Javier De Toro Francisco Javier Blanco | 2011 | World Journal of Orthopedics2011，2，6： | 7 |
| 2 | Sessile serrated adenomas:Demographic,endoscopic and pathological characteristics显示文摘AIM:To study the demographic and endoscopic characteristics of patients with sessile serrated adenoma(SSA) in a single center.METHODS:Patients with SSA were identified by review of the pathology database of Mayo Clinic Arizona from 2005 to 2007.A retrospective chart review was performed to extract data on demographics,polyp characteristics,presence of synchronous adenomatous polyps or cancer,polypectomy methods,and related complications.RESULTS:One hundred and seventy-one(2.9%) of all patients undergoing colonoscopy had a total of 226 SSAs.The mean(SE) size of the SSAs was 8.1(0.4) mm;42% of SSAs were ≤ 5 mm,and 69% were ≤ 9 mm.Fifty-one per cent of SSAs were located in the cecum or ascending colon.Approximately half of the patients had synchronous polyps of other histological types,including hyperplastic and adenomatous polyps.Synchronous adenocarcinoma was present in seven(4%) cases.Ninety-seven percent of polyps were removed by colonoscopy.CONCLUSION:Among patients with colon polyps,2.9% were found to have SSAs.Most of the SSAs were located in the right side and were safely managed by colonoscopy. | Suryakanth R Gurudu Russell I Heigh Giovanni De Petris Evelyn G Heigh Jonathan A Leighton Shabana F Pasha Isaac B Malagon Ananya Das | 2010 | World Journal of Gastroenterology2010，16，27： | 7 |
| 3 | Endoscopic retrograde cholangiography for pediatric choledocholithiasis: Assessing the need for endoscopic intervention显示文摘AIM:To assess pediatric patients for choledocholithiasis.We applied current adult guidelines to identify predictivefactors in children.METHODS:A single-center retrospective analysis was performed at a tertiary children's hospital.We evaluated 44 consecutive pediatric patients who underwent endoscopic retrograde cholangiography(ERCP) for suspected choledocholithiasis.Patients were stratified into those with common bile duct stones(CBDS) at ERCP vs those that did not using the American Society of Gastrointestinal Endoscopy(ASGE) guidelines(Very Strong and Strong criteria) for suspected CBDS.RESULTS:CBDS were identified in 84% at the time of ERCP.Abdominal ultrasound identified CBDS in 36% of patients.Conjugated bilirubin ≥ 0.5 mg/d L was an independent risk factor for CBDS(P = 0.003).The Very Strong(59.5%) and Strong(48.6%) ASGE criteria identified the majority of patients(P = 0.0001).A modified score using conjugated bilirubin had a higher sensitivity(81.2% vs 59.5%) and more likely to identify a stone than the standard criteria,odds ratio of 25.7 compared to 8.8.Alanine aminotransferase and gamma-glutamyl transferase values identified significant differences in a subset of patients with odds ratio of 4.1 and 3.25,respectively.CONCLUSION:Current adult guidelines identified the majority of pediatric patients with CBDS,but specific pediatric guidelines may improve detection,thus decreasing risks and unnecessary procedures. | Douglas S Fishman Bruno P Chumpitazi Isaac Raijman Cynthia Man-Wai Tsai E O’Brian Smith Mark V Mazziotti Mark A Gilger | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，11： | 6 |
| 4 | Do age-associated changes of voltage-gated sodium channel isoforms expressed in the mammalian heart predispose the elderly to atrial fibrillation?显示文摘Atrial fibrillation(AF)is the most common cardiac arrhythmia worldwide.The prevalence of the disease increases with age,strongly implying an age-related process underlying the pathology.At a time when people are living longer than ever before,an exponential increase in disease prevalence is predicted worldwide.Hence unraveling the underlying mechanics of the disease is paramount for the development of innovative treatment and prevention strategies.The role of voltage-gated sodium channels is fundamental in cardiac electrophysiology and may provide novel insights into the arrhythmogenesis of AF.Na_v1.5 is the predominant cardiac isoform,responsible for the action potential upstroke.Recent studies have demonstrated that Na_v1.8(an isoform predominantly expressed within the peripheral nervous system)is responsible for cellular arrhythmogenesis through the enhancement of pro-arrhythmogenic currents.Animal studies have shown a decline in Na_v1.5 leading to a diminished action potential upstroke during phase 0.Furthermore,the study of human tissue demonstrates an inverse expression of sodium channel isoforms;reduction of Na_v1.5 and increase of Na_v1.8 in both heart failure and ventricular hypertrophy.This strongly suggests that the expression of voltage-gated sodium channels play a crucial role in the development of arrhythmias in the diseased heart.Targeting aberrant sodium currents has led to novel therapeutic approaches in tackling AF and continues to be an area of emerging research.This review will explore how voltage-gated sodium channels may predispose the elderly heart to AF through the examination of laboratory and clinical based evidence. | Emmanuel Isaac Stephanie M Cooper Sandra A Jones Mahmoud Loubani | 2020 | World Journal of Cardiology2020，12，4： | 3 |
| 5 | Diabetes mellitus, revascularization and outcomes in elderly patients with myocardial infarction-related cardiogenic shock显示文摘Background The prognostic role of diabetes mellitus(DM)in elderly patients with myocardial infarction-related cardiogenic shock(MI-CS)remains controversial.Little information exists about the impact of intensive cardiac care unit(ICCU)and revascularization on outcomes of elderly patients with MI-CS.We aimed to assess the prognostic impact of DM according to age in patients with MI-CS,and to analyze the impact ICCU management and revascularization on in-hospital mortality in MI-CS patients at older ages.Methods Discharge episodes with diagnosis of CS associated with MI were selected from the Spanish National Health System’s Basic Data Set.Centers were classified according to their availability of ICCU.Main outcome measured was in-hospital mortality.Results A total of 23,590 episodes of MI-CS were identified,of whom 12,447(52.8%)were in patients aged≥75 years.The impact of DM on in-hospital mortality was different among age subgroups.While in younger patients,DM was associated to a higher mortality risk(0.52 vs.0.47,OR=1.12,95%CI:1.06–1.18,χ^2<0.001),this association became non-significant in older patients(0.76 vs.0.81,χ^2=0.09).Adjusted mortality rate of MI-CS aged≥75 years was lower in patients admitted to hospitals with ICCU(adjusted mortality rate:74.2%vs.77.7%,P<0.001)and in patients undergoing revascularization(74.9%vs.77.3%,P<0.001).Conclusions Prognostic impact of DM in patients with MI-CS was different according to age,with a significantly lower impact at older ages.The availability of ICCU and revascularization were associated with better outcomes in these complex patients. | Miquel Gual Albert Ariza-Solé María García Márquez Cristina Fernández JoséL Bernal Francesc Formiga María-Isabel Barrionuevo JoséC Sánchez-Salado Victòria Lorente Júlia Pascual Isaac Llaó Oriol Alegre Angel Cequier Javier Elola | 2020 | Journal of Geriatric Cardiology2020，17，10： | 2 |
| 6 | Para-aortic lymph node involvement should not be a contraindication to resection of pancreatic ductal adenocarcinoma显示文摘BACKGROUND Para-aortic lymph nodes(PALN)are found in the aortocaval groove and they are staged as metastatic disease if involved by pancreatic ductal adenocarcinoma(PDAC).The data in the literature is conflicting with some studies having associated PALN involvement with poor prognosis,while others not sharing the same results.PALN resection is not included in the standard lymphadenectomy during pancreatic resections as per the International Study Group for Pancreatic Surgery and there is no consensus on the management of these cases.AIM To investigate the prognostic significance of PALN metastases on the oncological outcomes after resection for PDAC.METHODS This is a retrospective cohort study of data retrieved from a prospectively maintained database on consecutive patients undergoing pancreatectomies for PDAC where PALN was sampled between 2011 and 2020.Statistical comparison of the data between PALN+and PALN-subgroups,survival analysis with the Kaplan-Meier method and risk analysis with univariable and multivariable time to event Cox regression analysis were performed,specifically assessing oncological outcomes such as median overall survival(OS)and disease-free survival(DFS).RESULTS 81 cases had PALN sampling and 17(21%)were positive.Pathological N stage was significantly different between PALN+and PALN-patients(P=0.005),while no difference was observed in any of the other characteristics.Preoperative imaging diagnosed PALN positivity in one case.OS and DFS were comparable between PALN+and PALN-patients with lymph node positive disease(OS:13.2 mo vs 18.8 mo,P=0.161;DFS:13 mo vs 16.4 mo,P=0.179).No difference in OS or DFS was identified between PALN positive and negative patients when they received chemotherapy either in the neoadjuvant or in the adjuvant setting(OS:23.4 mo vs 20.6 mo,P=0.192;DFS:23.9 mo vs 20.5 mo,P=0.718).On the contrary,when patients did not receive chemotherapy,PALN disease had substantially shorter OS(5.5 mo vs 14.2 mo;P=0.015)and DFS(4.4 mo vs 9.8 mo;P<0.001).PALN involvement was not identified as an independent predictor for OS after multivariable analysis,while it was for DFS doubling the risk of recurrence.CONCLUSION PALN involvement does not affect OS when patients complete the indicated treatment pathway for PDAC,surgery and chemotherapy,and should not be considered as a contraindication to resection. | Rupaly Pande Shafiq Chughtai Manish Ahuja Rachel Brown David C Bartlett Bobby V Dasari Ravi Marudanayagam Darius Mirza Keith Roberts John Isaac Robert P Sutcliffe Nikolaos A Chatzizacharias | 2022 | World Journal of Gastrointestinal Surgery2022，14，5： | 2 |
