| 1 | Watch and wait approach in rectal cancer:Current controversies and future directions显示文摘According to the main international clinical guidelines,the recommended treatment for locally-advanced rectal cancer is neoadjuvant chemoradiotherapy followed by surgery.However,doubts have been raised about the appropriate definition of clinical complete response(cCR)after neoadjuvant therapy and the role of surgery in patients who achieve a cCR.Surgical resection is associated with significant morbidity and decreased quality of life(QoL),which is especially relevant given the favourable prognosis in this patient subset. Accordingly, therehas been a growing interest in alternative approaches with less morbidity,including the organ-preserving watch and wait strategy, in which surgery isomitted in patients who have achieved a cCR. These patients are managed with aspecific follow-up protocol to ensure adequate cancer control, including the earlyidentification of recurrent disease. However, there are several open questionsabout this strategy, including patient selection, the clinical and radiologicalcriteria to accurately determine cCR, the duration of neoadjuvant treatment, therole of dose intensification (chemotherapy and/or radiotherapy), optimal followupprotocols, and the future perspectives of this approach. In the present review,we summarize the available evidence on the watch and wait strategy in thisclinical scenario, including ongoing clinical trials, QoL in these patients, and thecontroversies surrounding this treatment approach. | Fernando López-Campos Margarita Martín-Martín Roberto Fornell-Pérez Juan Carlos García-Pérez Javier Die-Trill Raquel Fuentes-Mateos Sergio López-Durán JoséDomínguez-Rullán Reyes Ferreiro AlejandroRiquelme-Oliveira Asunción Hervás-Morón Felipe Couñago | 2020 | World Journal of Gastroenterology2020,26,29: | 10 |

| 3 | Laparoscopic approach in gastrointestinal emergencies显示文摘This review focuses on the laparoscopic approach to gastrointestinal emergencies and its more recent indications. Laparoscopic surgery has a specific place in elective procedures, but that does not apply in emergency situations. In specific emergencies, there is a huge range of indications and different techniques to apply, and not all of them are equally settle. We consider that the most controversial points in minimally invasive procedures are indications in emergency situations due to technical difficulties. Some pathologies, such as oesophageal emergencies, obstruction due to colon cancer, abdominal hernias or incarcerated postsurgical hernias, are nearly always resolved by conventional surgery, that is, an open approach due to limited intraabdominal cavity space or due to the vulnerability of the bowel. These technical problems have been solved in many diseases, such as for perforated peptic ulcer or acute appendectomy for which a laparoscopic approach has become a wellknown and globally supported procedure. On the other hand, endoscopic procedures have acquired further indications, relegating surgical solutions to a second place; this happens in cholangitis or pancreatic abscess drainage. This endoluminal approach avoids the need for laparoscopic development in these diseases. Nevertheless, new instruments and new technologies could extend the laparoscopic approach to a broader array of potentials procedures. There remains, however, a long way to go. | Rosa M Jimenez Rodriguez Juan José Segura-Sampedro Mercedes Flores-Cortés Francisco López-Bernal Cristobalina Martín Verónica Pino Diaz Felipe Pareja Ciuro Javier Padillo Ruiz | 2016 | World Journal of Gastroenterology2016,22,9: | 5 |

| 5 | Fecal immunochemical test accuracy in average-risk colorectal cancer screening显示文摘AIM:To assess the fecal immunochemical test(FIT)accuracy for colorectal cancer(CRC)and advanced neoplasia(AN)detection in CRC screening.METHODS:We performed a multicentric,prospective,double blind study of diagnostic tests on asymptomatic average-risk individuals submitted to screening colonoscopy.Two stool samples were collected and the fecal hemoglobin concentration was determined in the first sample(FIT1)and the highest level of both samples(FITmax)using the OC-sensor.Areas under the curve(AUC)for CRC and AN were calculated.The best FIT1and FITmax cut-off values for CRC were determined.At this threshold,number needed to scope(NNS)to detect a CRC and an AN and the cost per lesion detected were calculated.RESULTS:About 779 individuals were included.An AN was found in 97(12.5%)individuals:a CRC in 5(0.6%)and an advanced adenoma(≥10 mm,villous histology or high grade dysplasia)in 92(11.9%)subjects.For CRC diagnosis,FIT1 AUC was 0.96(95%CI:0.95-0.98)and FITmax AUC was 0.95(95%CI:0.93-0.97).For AN,FIT1 and FITmax AUC were similar(0.72,95%CI:0.66-0.78 vs 0.73,95%CI:0.68-0.79,respectively,P=0.34).Depending on the number of determinations and the positivity threshold cut-off used sensitivity for AN detection ranged between 28%and 42%and specificity between 91%and 97%.At the best cut-off point for CRC detection(115 ng/mL),the NNS to detect a CRC were 10.2 and 15.8;and the cost per CRC was 1814€and 2985€on FIT1 and FITmax strategies respectively.At this threshold the sensitivity,NNS and cost per AN detected were 30%,1.76,and 306€,in FIT1 strategy,and 36%,2.26€and 426€,in FITmax strategy,respectively.CONCLUSION:Performing two tests does not improve diagnostic accuracy,but increases cost and NNS to detect a lesion. | Vicent Hernandez Joaquin Cubiella M Carmen Gonzalez-Mao Felipe Iglesias Concepción Rivera M Begoa Iglesias Lucía Cid Ines Castro Luisa de Castro Pablo Vega Jose Antonio Hermo Ramiro Macenlle Alfonso Martínez-Turnes David Martínez-Ares Pamela Estevez Estela Cid M Carmen Vidal Angeles López-Martínez Elisabeth Hijona Marta Herreros-Villanueva Luis Bujanda Jose Ignacio Rodriguez-Prada the COLONPREV study investigators | 2014 | World Journal of Gastroenterology2014,20,4: | 4 |
| 6 | Effectiveness of an intervention for reducing social stigma towards mental illness in adolescents显示文摘AIM: To evaluate the effectiveness of an intervention for reducing social stigma towards mental illness in adolescents. The effect of gender and knowledge of someone with mental illness was measured. METHODS: Two hundred and eighty secondary school students were evaluated using the Community Attitudes towards Mental Illness(CAMI) questionnaire. The schools were randomized and some received the intervention and others acted as the control group. The programme consisted of providing information via a documentary film and of contact with healthcare staff in order to reduce the social stigma within the school environment. RESULTS: The intervention was effective in reducing the CAMI authoritarianism and social restrictiveness subscales. The intervention showed significant changes in girls in terms of authoritarianism and social restrictiveness, while boys only showed significant changes in authoritarianism. Following the intervention, a significant reduction was found in authoritarianism and social restrictiveness in those who knew someone with mental illness, and only in authoritarianism in those who did not know anyone with mental illness. CONCLUSION: The intervention was effective to reduce social stigma towards people with mental illness, especially in the area of authoritarianism. Some differences were found depending on gender and whether or not the subjects knew someone with mental illness. | Regina Vila-Badia Francisco Martínez-Zambrano Otilia Arenas Emma Casas-Anguera Esther García-Morales Raúl Villellas José Ramón Martín María Belén Pérez-Franco Tamara Valduciel Diana Casellas Mar García-Franco Jose Miguel Joaquim Balsera Gemma Pascual Eugènia Julia Susana Ochoa | 2016 | World Journal of Psychiatry2016,6,2: | 4 |
| 7 | Hepatic flow is an intraoperative predictor of early allograft dysfunction in whole-graft deceased donor liver transplantation: An observational cohort study显示文摘BACKGROUND Early allograft dysfunction(EAD)after liver transplantation(LT)is an important cause of morbidity and mortality.To ensure adequate graft function,a critical hepatocellular mass is required in addition to an appropriate blood supply.We hypothesized that intraoperative measurement of portal venous and hepatic arterial flow may serve as a predictor in the diagnosis of EAD.AIM To study whether hepatic flow is an independent predictor of EAD following LT.METHODS This is an observational cohort study in a single institution.Hepatic arterial blood flow and portal venous blood flow were measured intraoperatively by transit flow.EAD was defined using the Olthoff criteria.Univariate and multivariate analyses were used to determine the intraoperative predictors of EAD.Survival analysis and prognostic factor analysis were performed using the Kaplan-Meier and Cox regression models.RESULTS A total of 195 liver transplant procedures were performed between January 2008 and December 2014 in 188 patients.A total of 54(27.7%)patients developed EAD.The median follow-up was 39 mo.Portal venous flow,hepatic arterial flow(HAF)and total hepatic arterial flow were associated with EAD in both the univariate and multivariate analyses.HAF is an independent prognostic factor for 30-d patient mortality.CONCLUSION Intraoperative measurement of blood flow after reperfusion appears to be a predictor of EAD;Moreover,HAF should be considered a predictor of 30-d patient mortality. | Pablo Lozano Lominchar Maitane Igone Orue-Echebarria Lorena Martín Cristina Julia Lisbona María Magdalena Salcedo Luis Olmedilla Hemant Sharma Jose Manuel Asencio JoséAngel López-Baena | 2019 | World Journal of Hepatology2019,11,9: | 4 |
| 8 | Beta-blocker therapy in elderly patients with renal dysfunction and heart failure显示文摘OBJECTIVE To assess the role of beta-blockers(BB)in patients with chronic kidney disease(CKD)aged≥75 years.METHODS AND RESULTS From January 2008 to July 2014,we included 390 consecutive patients≥75 years of age with ejection fraction≤35%and glomerular filtration rate(GFR)≤60 m L/min per 1.73 m^2.We analyzed the relationship between treatment with BB and mortality or cardiovascular events.The mean age of our population was 82.6±4.1 years.Mean ejection fraction was 27.9%±6.5%.GFR was 60-45 m L/min per 1.73 m^2 in 50.3%of patients,45-30 m L/min per 1.73 m^2 in 37.4%,and<30 m L/min per 1.73 m^2 in 12.3%.At the conclusion of follow-up,67.4%of patients were receiving BB.The median follow-up was28.04(IR:19.41-36.67)months.During the study period,211 patients(54.1%)died and 257(65.9%)had a major cardiovascular event(death or hospitalization for heart failure).BB use was significantly associated with a reduced risk of death(HR=0.51,95%CI:0.35-0.74;P<0.001).Patients receiving BB consistently showed a reduced risk of death across the different stages of CKD:stage IIIa(GFR=30-45 m L/min per 1.73 m^2;HR=0.47,95%CI:0.26-0.86,P<0.0001),stage IIIb(GFR 30-45 m L/min per 1.73 m^2;HR=0.55,95%CI:0.26-1.06,P=0.007),and stages IV and V(GFR<30 m L/min per 1.73 m~2;HR=0.29,95%CI:0.11-0.76;P=0.047).CONCLUSIONS The use of BB in elderly patients with HFr EF and renal impairment was associated with a better prognosis.Use of BB should be encouraged when possible. | Juan Martínez-Milla Marcelino Cortés García Julia Anna Palfy Mikel Taibo Urquía Marta López Castillo Ana Devesa Arbiol Ana Lucía Rivero Monteagudo María Luisa Martín Mariscal Inés Jiménez-Varas Sem Briongos Figuero Juan Antonio Franco-Pelaéz JoséTuñón | 2021 | Journal of Geriatric Cardiology2021,18,1: | 3 |

| 11 | A framework infrageneric classification of Carex (Cyperaceae) and its organizing principles显示文摘Phylogenetic studies of Carex L.(Cyperaceae)have consistently demonstrated that most subgenera and sections are para-or polyphyletic.Yet,taxonomists continue to use subgenera and sections in Carex classification.Why?The Global Carex Group(GCG)here takes the position that the historical and continued use of subgenera and sections serves to(i)organize our understanding of lineages in Carex,(ii)create an identification mechanism to break the~2000 species of Carex into manageable groups and stimulate its study,and(iii)provide a framework to recognize morphologically diagnosable lineages within Carex.Unfortunately,the current understanding of phylogenetic relationships in Carex is not yet sufficient for a global reclassification of the genus within a Linnean infrageneric(sectional)framework.Rather than leaving Carex classification in its current state,which is misleading and confusing,we here take the intermediate steps of implementing the recently revised subgeneric classification and using a combination of informally named clades and formally named sections to reflect the current state of our knowledge.This hybrid classification framework is presented in an order corresponding to a linear arrangement of the clades on a ladderized phylogeny,largely based on the recent phylogenies published by the GCG.It organizes Carex into six subgenera,which are,in turn,subdivided into 62 formally named Linnean sections plus 49 informal groups.This framework will serve as a roadmap for research on Carex phylogeny,enabling further development of a complete reclassification by presenting relevant morphological and geographical information on clades where possible and standardizing the use of formal sectional names. | Eric H.Roalson Pedro Jiménez-Mejías Andrew L.Hipp Carmen Benítez-Benítez Leo P.Bruederle Kyong-Sook Chung Marcial Escudero Bruce A.Ford Kerry Ford Sebastian Gebauer Berit Gehrke Marlene Hahn Muhammad Qasim Hayat Mathias H.Hoffmann Xiao-Feng Jin Sangtae Kim Isabel Larridon Étienne Léveillé-Bourret Yi-Fei Lu Modesto Luceño Enrique Maguilla Jose IgnacioMárquez-Corro Santiago Martín-Bravo Tomomi Masaki Mónica Míguez Robert F.C.Naczi Anton A.Reznicek Daniel Spalink Julian R.Starr Uzma Tamara Villaverde Marcia J.Waterway Karen L.Wilson and Shu-Ren Zhang | 2021 | Journal of Systematics and Evolution2021,59,4: | 3 |
| 12 | Treatment 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 | 2016 | World Journal of Gastroenterology2016,22,29: | 3 |

| 14 | Effect of femtosecond laser-assisted lens surgery on the optic nerve head and the macula显示文摘AIM: To evaluate the effect of femtosecond laser-assisted lens surgery(FLALS;cataract surgery or refractive lens exchange) on the structure of the optic nerve head and the macula.METHODS: This prospective longitudinal study included healthy eyes undergoing FLALS. Eyes with glaucoma or any other ocular disease that could alter optical coherence tomography results were excluded. Retinal nerve fiber layer(RNFL), Bruch’s membrane opening-minimum rim width(BMO-MRW) and macular thickness(MT) were measured preoperatively, 1 and 6 mo after surgery using spectral-domain optical coherence tomography(SD-OCT). Changes between preoperative and postoperative values were evaluated.RESULTS: A total of 87 eyes of 46 patients were included in this study. Preoperative RNFL, BMO-MRW and MT in microns(μm) were 100.77±10.39, 330.31±49.99 and 276.30±33.39, respectively. Postoperative RNFL, BMO-MRW and MT were 104.74±11.55, 348.32±54.05 and 279.83±22.65 1 mo after surgery and 102.93±11.17, 343.11±53.4 and 278.90±22.19 6 mo after surgery, respectively;which equals an increase of 3.93%, 5.45% and 1.27%,respectively, 1 mo after surgery, and 2.14%, 3.87% and 0.94% 6 mo after surgery. The differences between the preoperative and the postoperative RNFL and BMO-MRW values were statistically significant(P<0.001). Regarding MT values, there were not statistically significant differences(P=0.26).CONCLUSION: Our study suggests that FLALS does not have a negative impact on the structural status of the optic nerve head in healthy eyes, assessed by SD-OCT. There is a slight increase in the values of RNFL, BMO-MRW and MT 1 mo and 6 mo after surgery. | Josefina Renones de Abajo Beatriz Estévez Jorge Jesús María González Martín Humberto Carreras Díaz Juan Francisco Loro Ferrer Alfonso Antón López | 2019 | International Journal of Ophthalmology(English edition)2019,12,6: | 2 |
| 15 | Recombinant streptokinase vs hydrocortisone suppositories in acute hemorrhoids:A randomized controlled trial显示文摘AIM: To compare the efficacy and safety of recombinant streptokinase(rSK) vs hydrocortisone acetate-based suppositories in acute hemorrhoidal disease.METHODS: A multicenter(11 sites), randomized(1:1:1), open, controlled trial with parallel groups was performed. All participating patients gave their written,informed consent. After inclusion, patients with acute symptoms of hemorrhoids were centrally randomized to receive, as outpatients, by the rectal route, suppositories of rSK 200000 IU of one unit every 8 h(first 3 units)and afterwards every 12 h until 8 administrations were completed(schedule A), one unit every 8 h until 6 units were completed(schedule B), or 25 mg hydrocortisone acetate once every 8 h up to a maximum of 24 administrations. Evaluations were performed at 3, 5,and 10 d post-inclusion. The main end-point was the 5thday response(disappearance of pain and bleeding, and≥ 70% reduction of the lesion size). Time to response and need for thrombectomy were secondary efficacy variables. Adverse events were also evaluated.RESULTS: Groups were homogeneous with regards to demographic and baseline characteristics. Fifth day complete response rates were 156/170(91.8%; 95%CI:87.3-96.2), 155/170(91.2%; 95%CI: 86.6%-95.7%),and 46/170(27.1%; 95%CI: 20.1%-34.0%) with rSK(schedule A and B) and hydrocortisone acetate suppositories, respectively. These 64.6% and 63.9%differences(95%CI: 56.7%-72.2% and 55.7%-72.0%)were highly significant(P < 0.001). This advantage was detected since the early 3rd day evaluation(68.8% and64.1% vs 7.1% for the rSK and active control groups,respectively; P < 0.001) and was maintained even at the late 10 th day assessment(97.1% and 93.5% vs67.1% for rSK and hydrocortisone acetate, respectively;P < 0.001). Time to response was 3 d(95%CI: 2.9-3.1)for both rSK groups and 10 d(95%CI: 9.3-10.7) in the hydrocortisone acetate group. This difference was highly significant(P < 0.001). All subgroup stratified analyses(with or without thrombosis and hemorrhoid classification) showed a statistically significant advantage for the rSK groups. Thrombectomy was necessary in4/251 and 14/133 patients with baseline thrombosis in the rSK and hydrocortisone acetate groups, respectively(P < 0.001). There were no adverse events attributable to the experimental treatment.CONCLUSION: rSK suppositories showed a significant advantage over a widely-used over-the-counter hydrocortisone acetate preparation for the treatment of acute hemorrhoidal illness, as well as having an adequate safety profile. | Francisco Hernández-Bernal Georgina Castellanos-Sierra Carmen M Valenzuela-Silva Karem M Catasús-Alvarez Osmany Martínez-Serrano Odalys C Lazo-Diago Cimara H Bermúdez-Badell José R Causa-García Juan E Domínguez-Suárez Pedro A López-Saura 无 | 2015 | World Journal of Gastroenterology2015,21,23: | 2 |

| 17 | Conservative management of perforated duodenal diverticulum: A case report and review of the literature显示文摘Duodenal diverticula are a relatively common condition. They are asymptomatic, unless they become complicated, with perforation being the rarest but most severe complication. Surgical treatment is the most frequently performed approach. We report the case of a patient with a perforated duodenal diverticulum, which was diagnosed early and treated conservatively with antibiotics and percutaneous drainage of secondary retroperitoneal abscesses. We suggest this method could be an acceptable option for the management of similar cases, provided that the patient is in good general condition and without septic signs. | David Martínez-Cecilia Alvaro Arjona Sánchez Manuel Gómez álvarez Eva Torres Tordera Antonio Luque Molina Victor Valentí Azcárate Javier Briceo Delgado Francisco Javier Padillo Pedro López-Cillero Sebastián Rufián Pea | 2008 | World Journal of Gastroenterology2008,14,12: | 2 |
| 18 | Effects of feeding yeast(Saccharomyces cerevisiae), organic selenium and chromium mixed on growth performance and carcass traits of hair lambs显示文摘Yeasts and organic minerals are used in diets to improve health, productive performance and some carcass characteristics of ruminants and non-ruminants. Thirty-two lambs(Pelibuey×Katahdin; BW=(30.55±1.67) kg; n=8) were used in a 56-d feeding experiment to study the effects of different levels of live yeast(Saccharomyces cerevisiae; yeast), selenium(Se) and chromium(Cr) mixed(Se-Cr), and a mixture of yeast-Se-Cr on growth performance and carcass traits. Animals were stratified by body weight(BW) and randomly assigned to one of four treatments: 1) control group(0.0 g kg–1 yeast); 2) yeast(1.50 g kg–1 dry matter intake(DMI) d–1); 3) Se-Cr premix(1.5 mg kg–1 DMI d–1 for each mineral); and 4) yeast-Se-Cr mixture. There were no treatment effects on final BW; whereas lambs fed Se-Cr or yeast-Se-Cr had higher(P<0.05) DMI than animals supplemented with only yeast. Average daily gain(ADG), gain:feed ratio, chop area, dorsal fat and carcass yield were similar(P>0.05) among treatment groups. In conclusion, supplementation with yeast, Se-Cr mixed or yeast-Se-Cr did not improve ADG, final BW, back fat content and carcass yield of growing of Pelibuey×Katahdin lambs. Supplementation with Se-Cr and yeast-Se-Cr increased DMI, and approximately 250 g ADG animal–1 d–1 was produced with no negative effects on growth and health of the animals. | Pedro A Hernández-García Alejandro Lara-Bueno Germán D Mendoza-Martínez José R Bárcena-Gama Fernando X Plata-Pérez Rufino López-Ordaz José A Martínez-García | 2015 | Journal of Integrative Agriculture2015,14,3: | 2 |
| 19 | Translational pancreatic cancer research:a comparative study on patient-derived xenograft models显示文摘AIM To assess the viability of orthotopic and heterotopic patient-derived pancreatic cancer xenografts implanted into nude mice.METHODS This study presents a prospective experimental analytical follow-up of the development of tumours in mice upon implantation of human pancreatic adenocarcinoma samples. Specimens were obtained surgically from patients with a pathological diagnosis of pancreatic adenocarcinoma. Tumour samples from pancreatic cancer patients were transplanted into nude mice in three different locations(intraperitoneal, subcutaneous and pancreatic). Histological analysis(haematoxylin-eosin and Masson's trichrome staining) and immunohistochemical assessment of apoptosis(TUNEL), proliferation(Ki-67), angiogenesis(CD31) and fibrogenesis(α-SMA) were performed. When a tumour xenograft reached the target size, it was reimplanted in a new nude mouse. Three sequential tumour xenograft generations were generated(F1, F2 and F3).RESULTS The overall tumour engraftment rate was 61.1%. The subcutaneous model was most effective in terms of tissue growth(69.9%), followed by intraperitoneal(57.6%) and pancreatic(55%) models. Tumour development was faster in the subcutaneous model(17.7 ± 2.6 wk) compared with the pancreatic(23.1 ± 2.3 wk) and intraperitoneal(25.0 ± 2.7 wk) models(P = 0.064). There was a progressive increase in the tumour engraftment rate over successive generations for all three models(F1 28.1% vs F2 71.4% vs F3 80.9%, P < 0.001). There were no significant differences in tumour xenograft differentiation and cell proliferation between human samples and the three experimental models among the sequential generations of tumour xenografts. However, a progressive decrease in fibrosis, fibrogenesis, tumour vascularisation and apoptosis was observed in the three experimental models compared with the human samples. All three pancreatic patient-derived xenograft models presented similar histological and immunohistochemical characteristics.CONCLUSION In our experience, the faster development andgreatest number of viable xenografts could make the subcutaneous model the best option for experimentation in pancreatic cancer. | Mercedes Rubio-Manzanares Dorado Luis Miguel Marín Gómez Daniel Aparicio Sánchez Sheila Pereira Arenas Juan Manuel Praena-Fernández Juan Jose Borrero Martín Francisco Farfán López Miguel ángel Gómez Bravo Jordi Muntané Relat Javier Padillo Ruiz | 2018 | World Journal of Gastroenterology2018,24,7: | 2 |
