RESUMEN
Background: Sleep quality has been always an important problem for patients after hepatectomy. The main purpose of the study is to investigate the effects of early ambulation on sleep quality in patients after liver resection via a quantitative study. Methods: Patients undergoing liver tumor resection were randomly divided into two groups, and the Pittsburgh Sleep Quality Index (PSQI) was used to assess the postoperative activities and sleep quality. Results: Patients who started early ambulation after liver resection had significantly better sleep quality, faster recovery of gastrointestinal function and shorter lengths of postoperative hospital stay compared with the control group. And there was no significant difference in the incidence of postoperative complications between the two groups. Conclusion: Early standardized physical activities are feasible for patients after liver resection, which can significantly improve patient's sleep quality, reduce patient's pain and the nursing workload, and achieve rapid recovery.
RESUMEN
The development of bifunctional non-noble metal electrocatalysts demonstrating high activity and stability for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is of great significance for renewable and clean energy. In this work, we report hierarchically structured integrated Fe-MoS2/Ni3S2/NF (NF = nickel foam) materials prepared by a facile in situ solvothermal method, and among them, the Fe-doped MoS2 was assembled into spine-like nanorods. The optimized electrocatalyst (denoted as Fe-MoS2/Ni3S2/NF-2) demonstrated excellent activity and durability for performing the HER and OER in an alkaline electrolyte (pH = 14) with low overpotentials of 130.6 mV and 256 mV (vs. RHE) at a current density of 10 mA cm-2, as well as no significant loss in catalytic performance even after 2000 cyclic voltammetry (CV) cycles. An outstanding durability of 180 h could be achieved for OER. The overall water splitting made up of the two-electrode system with Fe-MoS2/Ni3S2/NF-2 as both the anode and the cathode required a voltage of only 1.61 V to drive a current density of 10 mA cm-2 along with an outstanding long-term stability of 20 h, displaying its great potential for application in water splitting. The effective construction of multi-component synergistic structures shows a good pathway for high-performance electrocatalysis and energy storage.
RESUMEN
OBJECTIVE: This randomized controlled study investigated the feasibility of early ambulation after liver resection and the effect of the amount of activity on postoperative recovery. METHODS: A total of 120 patients who underwent liver resection were randomly divided into two groups for the comparative analysis of the following factors: amount of activity, pain control, sleeping state, perioperative gastrointestinal function recovery, incidence of complications and postoperative hospital stay. RESULTS: Compared with the control group, patients undergoing liver resection performing early postoperative ambulation had faster gastrointestinal function recovery (First exhaust time 2.2⯱â¯1.4 vs. 3.3⯱â¯2.3 pâ¯<â¯0.01; First flatus time 2.3⯱â¯1.7 vs. 3.1⯱â¯2.5 pâ¯=â¯0.04) and shorter postoperative hospital stays (6.6⯱â¯2.3 vs. 7.7⯱â¯2.1 pâ¯=â¯0.01), with statistically significant differences. There was no significant difference in the incidence of postoperative complications between the two groups (pâ¯>â¯0.05). CONCLUSION: Early ambulation after liver resection is safe and feasible. It can reduce the patient's pain and economic burden, increase the patient's comfort, reduce the nursing workload, achieve rapid recovery, and improve patient satisfaction.
