1Evidence 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 2016World Journal of Gastrointestinal Endoscopy2016,8,2:2

9Development and Validation of a Deep Learning Based Automated Minirhizotron Image Analysis Pipeline显示文摘Root systems of crops play a significant role in agroecosystems.The root system is essential for water and nutrient uptake,plant stability,symbiosis with microbes,and a good soil structure.Minirhizotrons have shown to be effective to noninvasively investigate the root system.Root traits,like root length,can therefore be obtained throughout the crop growing season.Felix Maximilian Bauer Lena Lärm Shehan Morandage Guillaume Lobet Jan Vanderborght Harry Vereecken Andrea Schnepf 2022Plant Phenomics2022,4,1:1

11Faecal calprotectin and magnetic resonance imaging in detecting Crohn's disease endoscopic postoperative recurrence显示文摘AIM To assess magnetic resonance imaging(MRI) and faecal calprotectin to detect endoscopic postoperative recurrence in patients with Crohn's disease(CD).METHODS From two tertiary centers, all patients with CD who underwent ileocolonic resection were consecutively and prospectively included. All the patients underwent MRI and endoscopy within the first year after surgery or after the restoration of intestinal continuity [median = 6 mo(5.0-9.3)]. The stools were collected the day before the colonoscopy to evaluate faecal calprotectin level. Endoscopic postoperative recurrence(POR) was defined as Rutgeerts' index ≥ i2b. The MRI was analyzed independently by two radiologists blinded from clinical data.RESULTS Apparent diffusion coefficient(ADC) was lower in patients with endoscopic POR compared to those with no recurrence(2.03 ± 0.32 vs 2.27 ± 0.38 × 10^(-3) mm^2/s, P = 0.032). Clermont score(10.4 ± 5.8 vs 7.4 ± 4.5, P = 0.038) and relative contrast enhancement(RCE)(129.4% ± 62.8% vs 76.4% ± 32.6%, P = 0.007) were significantly associated with endoscopic POR contrary to the magnetic resonance index of activity(Ma RIA)(7.3 ± 4.5 vs 4.8 ± 3.7; P = 0.15) and MR scoring system(P = 0.056). ADC < 2.35 × 10^(-3) mm^2/s [sensitivity = 0.85, specificity = 0.65, positive predictive value(PPV) = 0.85, negative predictive value(NPV) = 0.65] and RCE > 100%(sensitivity = 0.75, specificity = 0.81, PPV = 0.75, NPV = 0.81) were the best cutoff values to identify endoscopic POR. Clermont score > 6.4(sensitivity = 0.61, specificity = 0.82, PPV = 0.73, NPV = 0.74), Ma RIA > 3.76(sensitivity = 0.61, specificity = 0.82, PPV = 0.73, NPV = 0.74) and a MR scoring system ≥ MR1(sensitivity = 0.54, specificity = 0.82, PPV = 0.70, and NPV = 0.70) demonstrated interesting performances to detect endoscopic POR. Faecal calprotectin values were significantly higher in patients with endoscopic POR(114 ± 54.5 μg/g vs 354.8 ± 432.5 μg/g; P = 0.0075). Faecal calprotectin > 100 μg/g demonstrated high performances to detect endoscopic POR(sensitivity = 0.67, specificity = 0.93, PPV = 0.89 and NPV = 0.77).CONCLUSION Faecal calprotectin and MRI are two reliable tools to detect endoscopic POR in patients with CD.Pierre Baillet Guillaume Cadiot Marion Goutte Felix Goutorbe Hedia Brixi Christine Hoeffel Christophe Allimant Maud Reymond Hélène Obritin-Guilhen Benoit Magnin Gilles Bommelaer Bruno Pereira Constance Hordonneau Anthony Buisson 2018World Journal of Gastroenterology2018,24,5:1
