| 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 | Applications of finite element simulation in orthopedic and trauma surgery显示文摘Research in different areas of orthopedic and trauma surgery requires a methodology that allows both a more economic approach and the ability to reproduce different situations in an easy way. Simulation models have been introduced recently in bioengineering and could become an essential tool in the study of any physiological unity, regardless of its complexity. The main problem in modeling with finite elements simulation is to achieve an accurate reproduction of the anatomy and a perfect correlation of the different structures, in any region of the human body. Authors have developed a mixed technique, joining the use of a three-dimensional laser scanner Roland Picza captured together with computed tomography(CT) and 3D CT images, to achieve a perfect reproduction of the anatomy. Finite element(FE) simulation lets us know the biomechanical changes that take place after hipprostheses or osteosynthesis implantation and biological responses of bone to biomechanical changes. The simulation models are able to predict changes in bone stress distribution around the implant, so allowing preventing future pathologies. The development of a FE model of lumbar spine is another interesting application of the simulation. The model allows research on the lumbar spine, not only in physiological conditions but also simulating different load conditions, to assess the impact on biomechanics. Different degrees of disc degeneration can also be simulated to determine the impact on adjacent anatomical elements. Finally, FE models may be useful to test different fixation systems, i.e., pedicular screws, interbody devices or rigid fixations compared with the dynamic ones. We have also developed models of lumbar spine and hip joint to predict the occurrence of osteoporotic fractures, based on densitometric determinations and specific biomechanical models, including approaches from damage and fracture mechanics. FE simulations also allow us to predict the behavior of orthopedic splints applied to the correction of deformities, providing the recovering force-displacement and angle-moment curves that characterize the mechanical behavior of the splint in the overall range of movement. | Antonio Herrera Elena Ibarz José Cego?ino Antonio Lobo-Escolar Sergio Puértolas Enrique López Jesús Mateo Luis Gracia | 2012 | World Journal of Orthopedics2012，3，4： | 8 |
| 4 | Intravitreal dexamethasone implants for diabetic macular edema显示文摘AIM: To evaluate the safety and efficacy of a dexamethasone(DEX) intravitreal implant for diabetic macular edema(DME).METHODS: Totally 113 eyes of 84 patients were divided in three subgroups: naive patients(n=11), pseudophakic patients(n=72) and phakic patients(n=30). Inclusive criterion comprised adult diabetic patients with central fovea thickening and impaired visual acuity resulting from DME for whom previous standard treatments showed no improvement in both central macular thickness(CMT) and best corrected visual acuity(BCVA) after at least 3 mo of treatment. Outcome data were obtained from patient visits at baseline and at months 1, 3, 5, 9 and 12 after the first DEX implant injection. At each of these visits, patients underwent measurement of BCVA, a complete eye examination and measurement of CMT and macular volume(MV) carried out with optical coherence tomography(OCT) images. RESULTS: Seventy-three eyes(64.5%) received a single implant, 30(26.5%) received two implants and 10(9%) received three implants. At baseline, average in BCVA, CMT and MV were 43.5±20.8, 462.8±145 and 12.6±2.5 respectively. These values improved significantly at 1 mo(BCVA: 47.2±19.5, CMT: 339.6±120, MV: 11.11±1.4) and 3 mo(BCVA: 53.2±18.1, CMT: 353.8±141, MV: 11.3±1.3)(P≤0.05). At 5 mo(BCVA: 50.9±19.8, CMT: 425±150, MV: 12.27±2.3), 9 mo(BCVA: 48.4±17.6, CMT: 445.5±170, MV: 12.5±2.3) and 12 mo(BCVA: 47.7±18.8, CMT: 413.2±149, MV: 12.03±2.5), improvements in the three parameters were no longer statistically significant and decreased progressively but did not reach baseline values. There were no clinical differences between subgroups. Ocular complications were minimal.CONCLUSION: Patients with DEX implants show maximum efficacy at 3 mo which then declined progressively, but is still better than baseline values at the end of follow-up. | Alicia Pareja-Ríos Paloma Ruiz-de la Fuente-Rodríguez Sergio Bonaque-González Maribel López-Gálvez Virginia Lozano-López Pedro Romero-Aroca | 2018 | International Journal of Ophthalmology(English edition)2018，11，1： | 8 |
| 5 | Identification of human papillomavirus in esophageal squamous papillomas显示文摘AIM:To investigate the presence of human papillomavirus (HPV) in esophageal squamous papilloma (ESP) and determine p16, p53 and Ki67 expression in a Mexican cohort. METHODS: Nineteen cases diagnosed as ESP, corresponding to 18 patients were reviewed; nineteen cases of normal esophageal mucosa were used as negative controls. HPV detection was performed by amplified chromogenic in situ hybridization (ACISH) using a wide spectrum-cocktail probe and PCR. RESULTS: The average age at presentation was 46.3 years (range 28-72 years). Patients included four (22.22%) males and 14 (77.77%) females. The most frequent location was upper third (11 cases), followed by middle third (3 cases) and unknown site (5 cases). Immunohistochemistry (IHC) revealed basal and focal p53 expression in 17 cases (89%); p16 was expressed in eight cases (42.10%) and the Ki67 index ranged from 10% to 30%. HPV was detected in 14 out of 16 cases (87.5%) by ACISH: Twelve showed diffuse nuclear patterns and two showed granular patterns. HPV DNA was identified by PCR in 12 out of 14 cases (85.7%). Low-risk HPV types were detected in the most of the cases. CONCLUSION: This study provides identification of HPV infection in almost 80% of ESP using either ACISH or PCR; overall, all of these lesions show low expression of cell-cycle markers. We suggest ACISH as an alternative diagnostic tool for HPV detection in ESP. | Olga L Bohn Leticia Navarro Jesus Saldivar Sergio Sanchez-Sosa | 2008 | World Journal of Gastroenterology2008，14，46： | 5 |

| 10 | Evidence to suggest adoption of water exchange deservesbroader consideration:Its pain alleviating impact occurs in90%of investigators显示文摘AIM: To determine variations in colonoscopy real-time insertion pain among investigators using three different insertion techniques.METHODS: From March 2013 through June 2014, 18-85-year-old diagnostic and 50-70-year-old screening patients were enrolled at each center to on-demand sedation colonoscopy with water exchange(WE), water immersion(WI) and insufflation with air or CO2 for insertion and withdrawal [air or carbon dioxide(AICD)]. Data were aggregated for analysis. Primary outcome: Variations in real-time maximum insertion pain(0 = none, 1-2 = discomfort, 10 = worst).RESULTS: One thousand and ninety-one cases analyzed: WE(n = 371); WI(n = 338); AICD(n = 382). Demographics and indications were comparable. The WE group had the lowest real-time maximum insertion pain score, mean(95%CI): WE 2.8(2.6-3.0), WI 3.8(3.5-4.1) and AICD 4.4(4.1-4.7), P < 0.0005. Ninety percent of the colonoscopists were able to use water exchange to significantly decrease maximum insertion pain scores. One investigator had high insertion pain in all groups, nonetheless WE achieved the lowest real-time maximum insertion pain score. WE had the highest proportions of patients with painless unsedated colonoscopy(vs WI, P = 0.013; vs AICD, P < 0.0005); unsedated colonoscopy with only minor discomfort(vs AICD, P < 0.0005), and completion without sedation(vs AICD, P < 0.0005).CONCLUSION: Aggregate data confirm superiority of WE in lowering colonoscopy real-time maximum insertion pain and need for sedation. Ninety percent of investigators were able to use water exchange to significantly decrease maximum insertion pain scores. Our results suggest that the technique deserves consideration in a broader scale. | Sergio Cadoni Mauro Liggi Premysl Falt Stefano Sanna Mariangela Argiolas Viviana Fanari Paolo Gallittu Donatella Mura Maria L Porcedda Vit Smajstrla Matteo Erriu Felix W Leung | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，2： | 2 |

| 13 | 在经历 transcatheter 的病人的 atrial 纤维性颤动的临床、预示的含意大动脉的阀门培植显示文摘 AIM: To study a cohort of consecutive patients under-going transcatheter aortic valve implantation (TAVI) and compare the outcomes of atrial fibrillation (AF) patients vs patients in sinus rhythm (SR). METHODS: All consecutive patients undergoing TAVI in our hospital were included. The AF group comprised patients in AF at the time of TAVI or with history of AF, and were compared with the SR group. Procedural, echocardiographic and follow-up variables were compared. Likewise, the CHA 2 DS 2-VASC stroke risk score and HAS-BLED bleeding risk score and antithrombotic treatment at discharge in AF patients were compared with that in SR patients. RESULTS: From a total of 34 patients undergoing TAVI, 17 (50%) were allocated to the AF group, of whom 15 (88%) were under chronic oral anticoagulation. Patients in the AF group were similar to those in the SR group except for a trend (P = 0.07) for a higher logistic EuroSCORE (28% vs 19%), and a higher prevalence of hypertension (82% vs 53%) and chronic renal failure (17% vs 0%). Risk of both stroke and bleeding was high in the AF group (mean CHA 2 DS 2-VASC 4.3, mean HAS-BLED 2.9). In the AF group, treatment at discharge included chronic oral anticoagulation in all except one case, and in association with an antiplatelet drug in 57% of patients. During a mean follow-up of 11 mo (maximum 32), there were only two strokes, none of them during the peri-procedural period: one in the AF group at 30 mo and one in the SR group at 3 mo. There were no statistical differences in procedural success, and clinical outcome (survival at 1 year 81% vs 74% in AF and SR groups, respectively, P = NS). CONCLUSION: Patients in AF undergoing TAVI show a trend to a higher surgical risk. However, in our cohort, patients in AF did not have a higher stroke rate compared to the SR group, and the prognosis was similar in both groups. | Pablo Salinas Raúl Moreno Luis Calvo Santiago Jiménez-Valero Guillermo Galeote Angel Sánchez-Recalde Teresa López-Fernández Sergio Garcia-Blas Diego Iglesias Luis Riera Isidro Moreno-Gómez Jose María Mesa Ignacio Plaza Rocio Ayala Rosa Gonzalez José-Luis López-Sendón | 2012 | World Journal of Cardiology2012，4，1： | 2 |
