1Metabolic complications in liver transplant recipients显示文摘The metabolic syndrome(MS), which includes obesity,dyslipidaemia, hypertension and hyperglycaemia according to the most widely accepted definitions now used, is one of the most common post-transplant complications, with a prevalence of 44%-58%. The MS, together with the immunosuppression, is considered the main risk factor for the development of cardiovascular disease(CVD) in transplant recipients, which in turn accounts for 19%-42% of all deaths unrelated to the graft. The presence of MS represents a relative risk for the development of CVD and death of 1.78. On the other hand, non-alcoholic fatty liver disease(NAFLD), considered as the manifestation of the MS in the liver, is now the second leading reason for liver transplantation in the United States after hepatitis C and alcohol. NAFLD has a high rate of recurrence in the liver graft and a direct relation with the worsening of other metabolic disorders, such as insulin resistance or diabetes mellitus. Consequently, it is vitally important to identify and treat as soon as possible such modifiable factors as hypertension, overweight, hyperlipidaemia or diabetes in transplanted patients to thus minimise the impact on patient survival. Additionally, steroid-free regimens are favoured, with minimal immunosuppression to limit the possible effects on the development of the MS.Miguel Jiménez-Pérez Rocío González-Grande Edith Omonte Guzmán Víctor Amo Trillo Juan Miguel Rodrigo López 2016World Journal of Gastroenterology2016,22,28:10
2New approaches in the treatment of hepatitis C显示文摘About 130-170 million people, is estimated to be infected with the hepatitis C virus(HCV). Chronic HCV infection is one of the leading causes of liverrelated death and in many countries it is the primaryreason for having a liver transplant. The main aim of antiviral treatment is to eradicate the virus. Until a few years ago the only treatment strategy was based on the combination of pegylated interferon and ribavirin(PEG/RBV). However, in genotypes 1 and 4 the rates of viral response did not surpass 50%, reaching up to 80% in the rest. In 2011 approval was given for the first direct acting antiviral agents(DAA), boceprevir and telaprevir, for treatment of genotype 1, in combination with traditional dual therapy. This strategy managed to increase the rates of sustained viral response(SVR) in both naive patients and in retreated patients, but with greater toxicity, interactions and cost, as well as being less safe in patients with advanced disease, in whom this treatment can trigger decompensation or even death. The recent, accelerated incorporation since 2013 of new more effective DAA, with pan-genomic properties and excellent tolerance, besides increasing the rates of SVR(even up to 100%), has also created a new scenario: shorter therapies, less toxicity and regimens free of PEG/RBV. This has enabled their almost generalised applicability in all patients. However, it should be noted that most of the scientific evidence available is based on expert opinion, case-control series, cohort studies and phase 2 and 3 trials, some with a reduced number of patients and select groups. Few data are currently available about the use of these drugs in daily clinical practice, particularly in relation to the appearance of side effects and interactions with other drugs, or their use in special populations or persons with the less common genotypes. This situation suggests the need for the generalised implementation of registries of patients receiving antiviral therapy. The main inconvenience of these new drugs is their high cost. This necessitates selection and prioritization of candidate patients to receive them, via strategies established by the various national organs, in accordance with the recommendations of scientific societies.rocío gonzález-grande miguel jiménez-pérez carolina gonzález arjona josémostazo torres 2016World Journal of Gastroenterology2016,22,4:9

4Timing, method and discontinuation of hydrocortisone administration for septic shock patients显示文摘AIM To characterize the prescribing patterns for hydrocortisone for patients with septic shock and perform an exploratory analysis in order to identify the variables associated with better outcomes.METHODS This prospective cohort study included 59 patients with septic shock who received stress-dose hydrocortisone.It was performed at 2 critical care units in academic hospitals from June 1st, 2015, to July 31 st, 2016. Demographic data, comorbidities, medical management details, adverse effects related to corticosteroids, and outcomes were collected after the critical care physician indicated initiation of hydrocortisone. Univariate comparison between continuous and bolus administration of hydrocortisone was performed, including multivariate analysis, as well as Kaplan-Meier analysis to compare the proportion of shock reversal at 7 d after presentation. Receiver operating characteristic(ROC) curves determined the best cut-off criteria for initiation of hydrocortisone associated with the highest probability of shock reversal. We addressed the effects of the taper strategy for discontinuation of hydrocortisone, noting risk of shock relapse and adverse effects.RESULTS All-cause 30-d mortality was 42%. Hydrocortisone was administered as a continuous infusion in 54.2% of patients; time to reversal of shock was 49 h longer in patients who were given a bolus administration [59 h(range, 47.5-90.5) vs 108 h(range, 63.2-189); P = 0.001]. The maximal dose of norepinephrine after initiation of hydrocortisone was lower in patients on continuous infusion [0.19 μg/kg per minute(range, 0.11-0.28 μg)] compared with patients who were given bolus [0.34 μg/kg per minute(range, 0.16-0.49); P = 0.004]. Kaplan-Meier analysis revealed a higher proportion of shock reversal at 7 d in patients with continuous infusion compared to those given bolus(83% vs 63%; P = 0.004). There was a good correlation between time to initiation of hydrocortisone and time to reversal of shock(r = 0.80; P < 0.0001); ROC curve analysis revealed that the best criteria for prediction of shock reversal was a time to initiation of hydrocortisone of ≤ 13 h after administration of norepinephrine, with an area under the curve of 0.81(P < 0.001). The maximal dose of norepinephrine at initiation of hydrocortisone with the highest association with shock reversal was ≤ 0.28 μg/kg per minute, with an area under the curve of 0.75(P = 0.0002). On a logistic regression model, hydrocortisone taper was not associated with a lower risk of shock relapse(RR = 1.29; P = 0.17) but was related to a higher probability of hyperglycemia [odds ratio(OR), 5.3; P = 0.04] and hypokalemia(OR = 10.6; P = 0.01). CONCLUSION Continuous infusion of hydrocortisone could hasten the resolution of septic shock compared to bolus administration. Earlier initiation corresponds with a higher probability of shock reversal. Tapering strategy is unnecessary.Miguel A Ibarra-Estrada Quetzalcóatl Chávez-Pe?a Claudia I Reynoso-Estrella Jorge Rios-Zerme?o Pável E Aguilera-González Miguel A García-Soto Guadalupe Aguirre-Avalos 2017World Journal of Critical Care Medicine2017,6,1:4
5Biliary cystadenoma显示文摘The diagnosis of cystadenoma is rare, even more so when located in the extrahepatic bile duct.Unspeciflc clinical signs may lead this pathology to be misdiagnosed.The need for pathological anatomy in order to distinguish cystadenomas from simple biliary cysts is crucial.The most usual treatment nowadays is resection of the bile duct, together with cholecystectomy and Roux-en-Y reconstruction.Miguel A Hernandez Bartolome Sagrario Fuerte Ruiz Israel Manzanedo Romero Beatriz Ramos Lojo Ignacio Rodriguez Prieto Luis Gimenez Alvira Rosario Granados Carreo Manuel Limones Esteban 2009World Journal of Gastroenterology2009,15,28:4
6Management of recurrent hepatitis C virus after liver transplantation显示文摘Chronic hepatitis C virus(HCV) infection is the leading cause of death from liver disease and the leading indication for liver transplantation(LT) in the United States and western Europe. LT represents the best therapeutic alternative for patients with advanced chronic liver disease caused by HCV or those who develop hepatocarcinoma. Reinfection by HCV of the graft is universal and occurs in 95% of transplant patients. This reinfection can compromise graft function and patient survival. In a few cases, the histological recurrence is minimal and non-progressive; however, in most patients it follows a more rapid course than in immunocompetent persons, and frequently evolves into cirrhosis with graft loss. In fact, the five-year and ten-year survival of patients transplanted because of HCV are 75% and 68%, respectively, compared with 85% and 78% in patients transplanted for other reasons. There is also a pattern of recurrence that is very severe, but rare(< 10%), called fibrosing cholestatic hepatitis, which often involves rapid graft loss. Patients who present a negative HCV viremia after antiviral treatment have better survival. Many studies published over recent years have shown that antiviral treatment of post-transplant HCV hepatitis carried out during the late phase is the best option for improving the prognosis of these patients. Until 2011, PEGylated interferon plus ribavirin was the standard of care, resulting in a sustained virological response in around 30% of recipients. The addition of protease inhibitors, such as boceprevir or telaprevir, to the standard of care, or the use of other direct-acting antiviral drugs may involve therapeutic changes in the context of HCV recurrence. This may result a better prognosis for these patients, particularly those with severe recurrence or factors predicting rapid progression of fibrosis. However, the use of these agents in LT still requires clarification in terms of safety and efficacy.Miguel Jiménez-Pérez Rocío González-Grande Francisco Javier Rando-Mu?oz 2014World Journal of Gastroenterology2014,20,44:3
7Management of hepatitis B virus infection after liver transplantation显示文摘Chronic hepatitis B virus(HBV) infection is responsible for up to 30% of cases of liver cirrhosis and up to 53% of cases of hepatocellular carcinoma. Liver transplantation(LT) is the best therapeutic option for patients with end-stage liver failure caused by HBV. The success of transplantation, though, depends on receiving prophylactic treatment against post-transplant viral reactivation. In the absence of prophylaxis, liver transplantation due to chronic hepatitis B(CHB) is associated with high rates of viral recurrence and poor survival. The introduction of treatment with hepatitis B immunoglobulins(HBIG) during the 1990 s and later the incorporation of oral antiviral drugs have improved the prognosis of these patients. Thus, LT for CHB is now a universally accepted option, with an estimated 5 years survival of around 85% vs the 45% survival seen prior to the introduction of HBIG. The combination of lamivudine plus HBIG has for many years been the most widely used prophylactic regimen. However, with the appearance of new more potent oral antiviral agents associated with less resistance(e.g., entecavir and tenofovir) for the treatment of CHB, new prophylactic strategies are being designed, either in combination with HBIG or alone as a monotherapy. These advances have allowed for more personalized prophylaxis based on the individual risk profile of a given patient. In addition, the small pool of donors has required the use of anti-HBc-positive donors(with the resulting possibility of transmitting HBV from these organs), which has been made possible by suitable prophylactic regimens.Miguel Jiménez-Pérez Rocío González-Grande José Mostazo Torres Carolina González Arjona Francisco Javier Rando-Mu?oz 2015World Journal of Gastroenterology2015,21,42:3
8运动表现分析:过去、现在与未来显示文摘对运动表现分析的发展历程、现状、未来进行研究发现,运动表现分析起源于标记分析,历经一个多世纪的实践与研究完成了由方法向方法论的转型,进入21世纪后逐渐发展成为运动科学(Sports Science)的一个新兴分支学科。在运动表现分析实践中采用定性、定量以及两者相结合的方法对“人的运动”进行直接描述和分析,分析手段主要包括标记分析和移动分析,通常需要从方法和学科2个层面来理解其定义。技术和战术表现评估、信效度分析、负荷监控以及学科交叉研究是近年来运动表现分析领域的研究热点。运动表现分析相关专业的设立以及运动表现分析师这一新职业的出现有力地推动了运动训练的科学化。当前,运动表现分析的理论基础、技术手段、人才培养和学科影响力等方面还面临挑战,未来其理论体系将趋向完善,向分析智能化、服务对象大众化和人才培养专业化等方向发展。易清 黎涌明 张铭鑫 崔一雄 刘天彪 张绍良 龚炳南 黄展煜 周长敬 MiguelÁngel Gómez Ruano Daniel Memmert Peter O'Donoghue 刘鸿优 2023上海体育学院学报2023,47,2:3
9Treatment of chronic hepatitis C with direct-acting antivirals: The role of resistance显示文摘The use of direct-acting antivirals(DAAs) to treat chronic hepatitis C has resulted in a significant increase in rates of sustained viral response(around 90%-95%) as compared with the standard treatment of peginterferon/ribavirin. Despite this, however, the rates of therapeutic failure in daily clinical practice range from 10%-15%. Most of these cases are due to the presence of resistant viral variants, resulting from mutations produced by substitutions of amino acids in the viral target protein that reduce viral sensitivity to DAAs, thus limiting the efficacy of these drugs. The high genetic diversity of hepatitis C virus has resulted in the existence of resistance-associated variants(RAVs), sometimes even before starting treatment with DAAs, though generally at low levels. These preexisting RAVs do not appear to impact on the sustained viral response, whereas those that appear after DAA therapy could well be determinant in virological failure with future treatments. As well as the presence of RAVs, virological failure to treatment with DAAs is generally associated with other factors related with a poor response, such as the degree of fibrosis, the response to previous therapy, the viral load or the viral genotype. Nonetheless, viral breakthrough and relapse can still occur in the absence of detectable RAVs and after the use of highly effective DAAs, so that the true clinical impact of the presence of RAVs in therapeutic failure remains to be determined.Miguel Jiménez-Pérez Rocío González-Grande Pilar Espana Contreras Isabel Pinazo Martínez Jesús de la Cruz Lombardo Raúl Olmedo Martín 2016World Journal of Gastroenterology2016,22,29:3

11Dendritic cell deficiencies persist seven months after SARS-CoV-2 infection显示文摘Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components.Dendritic cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFN-α).In COVID-19 there is a deficit in DC numbers and IFN-αproduction,which has been associated with disease severity.In this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory markers.Remarkably,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 infection.Moreover,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were observed.These findings contribute to a better understanding of the immunological sequelae of COVID-19.Alberto Pérez-Gómez Joana Vitallé Carmen Gasca-Capote Alicia Gutierrez-Valencia María Trujillo-Rodriguez Ana Serna-Gallego Esperanza Muñoz-Muela María de los Reyes Jiménez-Leon Mohamed Rafii-El-Idrissi Benhnia Inmaculada Rivas-Jeremias Cesar Sotomayor Cristina Roca-Oporto Nuria Espinosa Carmen Infante-Domínguez Juan Carlos Crespo-Rivas Alberto Fernández-Villar Alexandre Pérez-González Luis Fernando López-Cortés Eva Poveda Ezequiel Ruiz-Mateos JoséMiguel Cisneros Sonsoles Salto-Alejandre Judith Berastegui-Cabrera Pedro Camacho-Martínez Carmen Infante-Domínguez Marta Carretero-Ledesma Juan Carlos Crespo-Rivas Eduardo Márquez JoséManuel Lomas Claudio Bueno Rosario Amaya JoséAntonio Lepe Jerónimo Pachón Elisa Cordero Javier Sánchez-Céspedes Manuela Aguilar-Guisado Almudena Aguilera Clara Aguilera Teresa Aldabo-Pallas Verónica Alfaro-Lara Cristina Amodeo Javier Ampuero María Dolores Avilés Maribel Asensio Bosco Barón-Franco Lydia Barrera-Pulido Rafael Bellido-Alba Máximo Bernabeu-Wittel Candela Caballero-Eraso Macarena Cabrera Enrique Calderón Jesús Carbajal-Guerrero Manuela Cid-Cumplido Yael Corcia-Palomo Juan Delgado Antonio Domínguez-Petit Alejandro Deniz Reginal Dusseck-Brutus Ana Escoresca-Ortega Fátima Espinosa Nuria Espinosa Michelle Espinoza Carmen Ferrándiz-Millón Marta Ferrer Teresa Ferrer Ignacio Gallego-Texeira Rosa Gámez-Mancera Emilio García Horacio García-Delgado Manuel García-Gutiérrez María Luisa Gascón-Castillo Aurora González-Estrada Demetrio González Carmen Gómez-González Rocío González-León Carmen Grande-Cabrerizo Sonia Gutiérrez Carlos Hernández-Quiles Inmaculada Concepción Herrera-Melero Marta Herrero-Romero Luis Jara Carlos Jiménez-Juan Silvia Jiménez-Jorge Mercedes Jiménez-Sánchez Julia Lanseros-Tenllado Carmina López Isabel López Álvaro López-Barrios Luis F.López-Cortés Rafael Luque-Márquez Daniel Macías-García Guillermo Martín-Gutiérrez Luis Martín-Villén JoséMolina Aurora Morillo María Dolores Navarro-Amuedo Dolores Nieto-Martín Francisco Ortega María Paniagua-García Amelia Peña-Rodríguez Esther Pérez Manuel Poyato Julia Praena-Segovia Rafaela Ríos Cristina Roca-Oporto Jesús F.Rodríguez María Jesús Rodríguez-Hernández Santiago Rodríguez-Suárez Ángel Rodríguez-Villodres Nieves Romero-Rodríguez Ricardo Ruiz Zida Ruiz de Azua Celia Salamanca Sonia Sánchez Víctor Manuel Sánchez-Montagut César Sotomayor Alejandro Suárez Benjumea Javier Toral 2021Cellular & Molecular Immunology2021,18,9:2
