Transcutaneous Electrical Acupoints Stimulation Improves Spontaneous Voiding Recovery After Laparoscopic Cholecystectomy: A Randomized Clinical Trial.

BACKGROUND: Facilitating the recurrence of spontaneous voiding is considered to be a way to prevent urinary retention after surgery, which is of great importance in cholecystectomy. This study aimed to assess the effect of transcutaneous electrical acupoint stimulation (TEAS) on spontaneous voiding recovery after laparoscopic cholecystectom. METHODS: Participants who underwent elective laparoscopic cholecystectomy were randomly assigned to either the TEAS group or the sham group. Active TEAS or sham TEAS at specific acupuncture points was conducted intraoperatively and postoperatively. The primary outcome was the recovery speed of spontaneous voiding ability after surgery and secondary outcomes included postoperative urinary retention (POUR), voiding dysfunction, pain, anxiety and depression, and early recovery after surgery. RESULTS: A total of 1,948 participants were recruited and randomized to TEAS (n = 975) or sham (n = 973) between August 2018 and June 2020. TEAS shortens the time delay of the first spontaneous voiding after laparoscopic cholecystectomy (5.6 h [IQR, 3.7-8.1 h] in the TEAS group vs 7.0 h [IQR, 4.7-9.7 h] in the sham group) (p < 0.001). The TEAS group experienced less POUR (p = 0.020), less voiding difficulty (p < 0.001), less anxiety and depression (p < 0.001), reduced pain (p = 0.007), and earlier ambulation (p = 0.01) than the sham group. CONCLUSIONS: Our results showed that TEAS is an effective approach to accelerate the recovery of spontaneous voiding and reduce POUR which facilitates recovery for patients after laparoscopic cholecystectomy.

Real-time use of a computer-aided system for polyp detection during colonoscopy, an ambispective study.

OBJECTIVE: This study aimed to evaluate ambispectively the effectiveness of a real-time computer-aided detection (CADe) system on the number of polyp (PPC) or adenoma per colonoscopy (APC), and polyp (PDR) or adenoma detection rate (ADR). METHODS: Eight-five videos marked using the CADe system, together with the unmarked videos, were reviewed by two senior endoscopists. Polyps detected in the marked and unmarked videos were recounted in parallel. Additionally, 128 consecutive patients were enrolled for a prospective evaluation using a standard colonoscopy or the CADe monitor alternately every 2 weeks. The PC, APC, PDR and ADR were compared between the two groups. RESULTS: The total number of polyps reported in the unmarked and marked videos were 73 and 88, respectively (mean PPC 0.86 vs 1.04, P = 0.001). The proportion of polyps detected per colonoscopy increased by 20.5%. Of the 128 prospectively enrolled patients, 186 polyps were detected. The mean PPC was higher in the CADe colonoscopy than in the standard colonoscopy (1.66 vs 1.13, P = 0.039). The PDR using the CADe colonoscopy was significantly higher than that of the standard colonoscopy (78.1% vs 56.3%, P = 0.008). CONCLUSION: Real-time CADe system significantly increases the PDR and PPC under the situation of a high rate of polyp detection.

[Physical activities and dietary intervention on metabolic syndrome in children].

OBJECTIVE: To study the effect of physical activities and dietary intervention on metabolic syndrome (MS) in primary school students. METHODS: Either one-year physical activities (PA) or dietary intervention was conducted in Grade 1-5 children from eight primary schools in Haidian district, Beijing. A 'happy 10 minutes' program was held in the PA group, while the dietary group receiving nutrition lectures. Baseline and post-intervention data on height, weight, waist circumference, serum lipids, glucose, and blood pressure were collected. RESULTS: The prevalence of MS at baseline was 9.0%. After intervention programs were carried out, improvements on triglyceride, high density lipoprotein, fasting blood glucose, diastolic blood pressure and waist circumference in the dietary group or PA group were seen, with the dietary group showed better effects than the PA group. The prevalence of MS decreased from 10.4% to 4.6% in the dietary group with statistically significant difference, while it increased in both the PA group and the control group. Girls showed better effects in the dietary group. Older students showed better effects than the younger students in the PA group. In non-overweight and overweight students of the dietary intervention group, the MS related components were significantly improved. CONCLUSION: The prevalence of metabolic syndrome was relatively high in the primary school students in Beijing. Education on nutrition could reduce the prevalence and improve the related components, which seemed to be more effective than in the PA intervention. Sex, age and nutritional status were the confounding factors for intervention programs.
