The C-index of the RFS nomogram was 0.850, which was higher than that of the AGR, the NMLR and the TNM stage. Analogously, the areas under the receiver operating characteristics curves (AUROCs, 0.920 for OS and 0.897 for RFS, respectively) of the two nomograms were higher than that of the NMLR, the AGR and the TNM stage. In the internal validation cohort, the C-indexes of the OS and RFS nomograms were 0.812 and 0.826, respectively. In the external validation cohort, the C-indexes of the OS and RFS nomograms were 0.866 and 0.880, respectively.The proposed nomograms including nutrition and immunity parameters were proved to have excellent predictive ability in survival and recurrence for patients with GC after R0 resection.The effects of exercise interventions on blood pressure control in hypertensive patients have received extensive attention and recognition. However, the influence of exercise-related behaviors on the effects of blood pressure control and the management factors that affect exercise behaviors remain inconclusive. Therefore, this study aimed to explore the relationships between exercise and exercise-related behaviors and blood pressure control, expecting to provide a scientific basis for further improvement of exercise intervention programs for patients with hypertension.Long-term residents in a community in Fuzhou, Fujian Province, China who were diagnosed with hypertension at a medical facility were recruited for this study. Hypertensive patients with uncontrolled blood pressure were placed in the case group, and those with controlled blood pressure were placed in the control group. The count data were analyzed with the χ test based on α = 0.05. A univariate logistic regression analysis was performed to screen% CI 1.279-3.954), health belief (OR = 0.016, 95% CI 0.004-0.059), and company of a family member during exercise (OR = 0.048, 95% CI 0.025-0.094) were significant factors predictive of regular exercise in hypertensive patients.Improving exercise-related behaviors and their management can help improve the effects of exercise interventions on blood pressure control in middle-aged and elderly hypertensive patients.OBJECTIVES To understand the possible effect of a novel salt substitute with very low sodium in reducing blood pressure, salt intake and use of anti-hypertensive medications among patients on regular medications, to inform the future randomized trials. DESIGN Single-arm pilot trial. SETTING A community health service center in Chongqing, China. PARTICIPANTS A total of 43 patients with hypertension taking anti-hypertensive medications regularly. INTERVENTION Patients received the salt substitute with 18% sodium chloride for 8 weeks. MAIN OUTCOME MEASURES Patients were followed up weekly for the use of antihypertensive medications and measurements of blood pressure. We collected 24-h urine before and after the trial to measure sodium and potassium intake. RESULTS Among 39 patients who completed the 8 weeks' intervention, 30.8% patients stopped or reduced anti-hypertensive medications during the trial. For patients that stopped or reduced medication, the mean SBP and DBP before intervention were 122.1 ± 9.6 and 68.9 ± 9.4 mm Hg and both did not increase after intervention (SBP change 2.8 mm Hg (-5.1, 10.8), P = .48; DBP change 1.8 mm Hg (-2.2, 5.7), P = .38). For the rest patients, the mean SBP and DBP before intervention were 141.6 ± 16.9 and 74.6 ± 6.6 mm Hg but reduced significantly after the intervention (SBP change -16.0 mm Hg (-21.3, -10.6), P  less then  .001; DBP change -5.5 mm Hg (-8.1, -2.9), P  less then  .001). The 24-h urine sodium decreased (P  less then  .001) and potassium increased (P  less then  .001) among all patients. No severe adverse events were reported. CONCLUSIONS The novel salt substitute showed potential in reducing blood pressure and use of antihypertensive medications. Further randomized double-blind controlled trial is warranted to validate these findings.Clinical Trial Registration-URLhttp//www.clinicaltrials.gov. Unique identifier NCT03226327.Barrett's esophagus has 0.5% to 7% risk of progression to esophageal adenocarcinoma. The method of obtaining biopsies to diagnose Barrett's is challenging. Seattle protocol has been considered as the gold standard, however its difficulty limits its applicability in practice. Narrow band imaging guided biopsy has been proposed as an alternative.To investigate the accuracy, sensitivity, specificity and applicability of Narrow band guided biopsy as a screening tool for Barret's esophagus in gastroesophageal reflux patients.Endoscopy was done in 2 different sessions 2 weeks apart for 100 patients in Alexandria, Egypt. Patients had at least one of the following Chronic Gastroesophageal reflux disease, frequent Gastroesophageal reflux disease, or two or more risk factors for Barrett's esophagus. selleck All patients with known Barrett's esophagus were excluded.Seventeen patients had Barrett's esophagus either by one of the two techniques or by both, 4 patients by both methods, 7 patients by narrow band imaging alone and 6 patients by Seattle protocol alone (P  less then  .001, κ = 0.461). Sensitivity, specificity, negative predictive value and positive predictive value for Seattle protocol were 58.8%, 100%, 92.2%, 100% vs 76.5%, 100%, 95.4%, 100% respectively for narrow band imaging. A mean of 7.73 samples/patient was taken in Seattle protocol vs 3.42 samples in narrow band imaging (P  less then  .001). A mean of 8.63 minutes was consumed in Seattle protocol vs 2.65 minutes in narrow band imaging (P  less then  .001).Narrow band imaging guided biopsy might have higher accuracy, sensitivity and negative predictive value as well as fewer number of biopsies and shorter time of the procedure compared to Seattle protocol which might increases its applicability as screening protocol for Barrett's esophagus. However, further larger multicentric studies are needed.BACKGROUND The aim of this study was to evaluate the effectiveness and safety of surgical treatment of intra-articular distal radius fractures (DRFs) with the assistance of three-dimensional (3D) printing technique. METHODS Patients with intra-articular DRFs in our hospital from February 2017 to November 2018 were enrolled in this study, and were randomly assigned to 2 parallel groups to receive surgical treatment with the assistance of 3D printing technique or not. For patients in the 3D printing group, the surgical procedure was simulated with 3D physical model before surgery. Volar plate and K-wire fixation were performed in all patients. Patients in the 2 groups were compared in terms of intraoperative indexes and postoperative function. RESULTS A total of 32 patients were included in our study. During surgery, mean operation time in the 3D model group was significantly lower than that in the routine group (P  .05). CONCLUSION With the assistance of 3D printing technique, the operation time, amount of intraoperative bleeding, and times of intraoperative fluoroscopy can be reduced during the surgical treatment of intra-articular DRFs with volar plating and K-wire fixation.
