1%). Overall, 25,554 mentions were documented from 1205 outputs (97.0% by Twitter). A greater percentage of "other studies" ranked in the lower Altmetric score categories (p = 0.0007). Similarly, the median Altmetric score was higher in the RCT subgroup comparing with "other studies" (6.5 vs. 2.0, Mann-Whitney p = 0.0001).

In this study, RCTs represented just the 7.1% of the studies and produced 11% of Twitter outputs. The median Altmetric scores obtained by RCTs were higher than those of other studies.

Feedback is a pivotal cornerstone and a challenge in psychomotor training. There are different teaching methodologies; however, some may be less effective.

A prospective randomized controlled trial was conducted in 130 medical students to compare the effectiveness of the video-guided learning (VLG), peer-feedback (PFG) and the expert feedback (EFG) for teaching suturing skills. The program lasted 4 weeks. Students were recorded making 3-simple stitches (pre-assessment and post-assessment). The primary outcome was a global scale (OSATS). The secondary outcomes were performance time, specific rating scale (SRS) and the impact of the intervention (IOI), defined as the variation between the final and initial OSATS and SRS scores.

No significant differences were found between PFG and EFG in post-assessment results of OSATS, SRS scores or in the IOI for OSATS and SRS scores. Post-assessment results of PFG and EFG were significantly superior to VLG in OSATS and SRS scores [(19.8 (18.5-21); 16.6 (15.5-17.5)) and (20.3 (19.88-21); 16.8 (16-17.5)) vs (15.7 (15-16); 13.3 (12.5-14)) (p < 0.05)], respectively. The results of PFG and EFG were significantly superior to VLG in the IOI for OSATS [7 (4.5-9) and 7.4 (4.88-10) vs 3.5 (1.5-6) (p < 0.05)] and SRS scores [5.4 (3.5-7) and 6.3 (4-8.5) vs 3.1 (1.13-4.88) (p < 0.05)], respectively.

The video-guided learning methodology without any kind of feedback is not enough for teaching suturing skills compared to expert or peer feedback. The peer feedback methodology appears to be a viable alternative to handling the emerging demands in medical education.

The optimal time interval to define early recurrence (ER) among patients who underwent resection of gallbladder cancer (GBC) is not well defined. We soughtto develop and validate a novel GBC recurrence risk (GBRR) score to predict ER among patients undergoing resection for GBC.

Patients who underwent curative-intent resection for GBC between 2000 and 2018 were identified from the US Extrahepatic Biliary Malignancy Consortiumdatabase. A minimum p value approach in the log-rank test was used to define the optimal cutoff forER. A risk stratification model was developed to predict ER based on relevant clinicopathological factors and was externally validated.

Among 309 patients, 103 patients (33.3%) had a recurrence at a median follow-up period of 15.1months. The optimal cutoff for ER was defined at 12months (p = 3.04 × 10

). On multivariable analysis, T3/T4 disease (HR 2.80; 95% CI 1.58-5.11) and poor tumordifferentiation (HR 1.91; 95% CI 1.11-3.25) were associated with greater hazards of ER. The GBRR scorout their prognosis.

This study aims to investigate the effect of lymph node examination on overall survival (OS) and lung cancer-specific survival (LCSS) in stage I second primary lung cancer (SPLC) patients who underwent second pulmonary resection.

We conducted a retrospective study with the Surveillance, Epidemiology, and End Results (SEER) database to identify stage I SPLC patients who received surgery from 1998 to 2015. The Kaplan-Meier method with landmark analysis and multivariable Cox regression analysis were performed to evaluate the prognostic value of lymph node examination.

A total of 842 patients from the SEER database with stage I SPLC who underwent a second surgical treatment were included. The 5-year survival rate was 54.8% for the whole cohort. Multivariable analysis revealed that the number of lymph nodes examined (LNE) was associated with better OS and LCSS in SPLC patients after 12months postoperatively. Patients with contralateral SPLC had significantly more nodes removed than those with ipsilateral SPLC. For contralateral SPLC, more than 10 LNE was correlated with improved long-term survival outcomes. Ipsilateral SPLC patients benefited from 4 or more LNE. However, the current analysis did not show a significant survival benefit from lymph node examination within 12months after surgery.

For stage I SPLC patients who received surgical treatment after initial resection, an adequate number of LNE would improve both OS and LCSS. We recommend more than 10 LNE for contralateral SPLC and at least 4 LNE for ipsilateral SPLC.

Whether robot-assisted minimally invasive surgery (RAMIE) is more beneficial than conventional minimally invasive surgery (MIE) remains unclear.

In total, 165 consecutive patients with esophageal carcinoma who underwent esophagectomy between January 2015 and April 2020 were retrospectively assessed. A 11 propensity score matching analysis was performed to compare the short-term outcomes between RAMIE and conventional MIE.

After matching, 45 patients were included in the RAMIE and conventional MIE groups. RAMIE had a significantly longer total operative time (708 vs. 612min, P < 0.001) and thoracic operative time (348 vs. 285min, P < 0.001) than conventional MIE. selleck inhibitor However, there were no significant differences in terms of oncological outcomes, such as R0 resection rate and number of resected lymph nodes. The overall postoperative morbidity (Clavien-Dindo [C-D] grade II or higher) rate of RAMIE and conventional MIE were 51% and 73% (P = 0.03), respectively, and the severe postoperative morbidity (C-D grade III or higher) rates were 11% and 29% (P = 0.
