BackgroundThe benefits of telemedicine include cost savings and decentralized care. Video consultation is one form that enables early detection of deteriorating patients and promotion of self-efficacy in patients who are well but anxious. Abdominal pain is a common symptom presented by patients in emergency departments. These patients could benefit from video consultation, as it enables remote follow-up of patients who do not require admission and facilitates early discharge of patients from overcrowded hospitals. ObjectiveThe study aimed to evaluate the safety and efficacy of the use of digital telereview in patients presenting with undifferentiated acute abdominal pain. MethodsThe SAVED study was a prospective randomized controlled trial in which follow-up using existing telephone-based telereview (control) was compared with digital telereview (intervention). Patients with undifferentiated acute abdominal pain discharged from the emergency department observation ward were studied based on intention-to-treat. The control arm received routine, provider-scheduled telereview with missed reviews actively coordinated and rescheduled by emergency department staff. The intervention arm received access to a platform for digital telereview (asynchronous and synchronous format) that enabled patient-led appointment rescheduling. Patients were followed-up for 2 weeks for outcomes of service utilization, efficacy (compliance with their disposition plan), and safety (re-presentation for the same condition). ResultsA total of 70 patients participated, with patients randomly assigned to each arm (1:1 ratio). Patients were a mean age of 40.0 (SD 13.8; range 22-71) years, predominantly female (47/70, 67%), and predominantly of Chinese ethnicity (39/70, 56%). The telereview service was used by 32 patients in the control arm (32/35, 91%) and 18 patients in the intervention arm (18/35, 51%). Most patients in control (33/35, 94%; 95% CI 79.5%-99.0%) and intervention (34/35, 97%; 95% CI 83.4%-99.9%) arms were compliant with their final disposition. There was a low rate of re-presentation at 72 hours and 2 weeks for both control (72 hours: 2/35, 6%; 95% CI 1.0%-20.5%; 2 weeks: 2/35, 6%, 95% CI 1.0%-20.5%) and intervention (72 hours: 2/35, 6%; 95% CI 1.0%-20.5%; 2 weeks: 3/35, 9%, 95% CI 2.2%-24.2%) arms. There were no significant differences in safety (P>.99) and efficacy (P>.99) between the two groups. ConclusionsThe application of digital telereview for the follow-up of patients with abdominal pain may be safe and effective. Future studies are needed to evaluate its cost-effectiveness and usefulness for broader clinical application. Trial RegistrationISRCTN Registry ISRCTN28468556; http://www.isrctn.com/ISRCTN28468556.

A new adsorbent(DES@ZIF@MG) was prepared by grafting deep eutectic solvents(DES) onto metal organic framework ZIF/magnetic reduced graphene oxide(MG) for the adsorption of methamphetamine. A series of structural characterization analyses (SEM, FT-IR, BET, VSM, TGA) were facilitated to explore the microscopic morphology and physicochemical properties of DES@ZIF@MG. The adsorption performances of methamphetamine onto the adsorbent were investigated by adsorption kinetics, isotherms, and adsorption effect experiments(pH, ionic strengths, and humic acid). The results showed that the adsorption of methamphetamine onto DES@ZIF@MG was consistent with the pseudo-second-order model and the Langmuir model, indicating that the adsorption process was an energetically homogeneous adsorption dominated by chemisorption. The XPS characterization illustrated that the adsorption process of methamphetamine by DES@ZIF@MG mainly involved hydrogen bonding, π-π interaction, electrostatic interaction, and chelation.

Background: Benign uretero‐ileal anastomotic stricture (UIAS) is a potentially serious complication that can arise after radical cystectomy (RC) and subsequent urinary diversion. To preserve residual renal function and improve prognosis, it is crucial to derive insights from experience and tailor individualized treatment strategies for different patients. Patients and Methods: From October 2014 to June 2021, a total of 47 patients with benign UIAS underwent endoscopic management (n = 19) or reimplantation surgery (n = 28). The basic data, perioperative conditions, and postoperative outcomes of the two groups were compared and analyzed to evaluate efficacy. Results: Comparing preoperative and postoperative clinical efficacy within the same group, the endoscopic group showed no significant differences in creatinine and blood urea nitrogen (BUN) levels before surgery or after extubation (p > 0.05). However, significant differences were observed in glomerular filtration rate (GFR) levels on the affected side before surgery and after extubation (p < 0.05). In contrast, the laparoscopic reimplantation group did not exhibit significant differences in creatinine, BUN, or GFR levels of affected side before surgery and after extubation (p > 0.05). Postoperative clinical efficacy showed no significant difference in creatinine and BUN levels between the two groups (p > 0.05). However, GFR values of affected side in the endoscopic treatment group decreased more than those in the laparoscopic reimplantation group (p < 0.05). Additionally, the laparoscopic reimplantation group was able to remove the single‐J tube earlier than the endoscopic treatment group (p < 0.05), had a lower recurrence rate of hydronephrosis after extubation (p < 0.05), and experienced a later onset of hydronephrosis compared to the endoscopic treatment group (p < 0.05). Conclusions: Based on our experience in treating UIAS following RC combined with urinary diversion, laparoscopic reimplantation effectively addresses the issue of UIAS, allowing for the removal of the ureteral stent relatively soon after surgery. This approach maintains long‐term ureteral patency, preserves residual renal function, reduces the risk of ureteral restenosis and hydronephrosis, and has demonstrated superior therapeutic outcomes in this study.
