Efficacy Study of Multidisciplinary Team Participating in the Perioperative Administration for Elderly Patients With Intertrochanteric Fractures: A Prospective Randomized Controlled Trail.

OBJECTIVE: To evaluate the efficacy of the multidisciplinary team (MDT) participating in the perioperative administration and 1-year follow-up for elderly patients with intertrochanteric fractures. METHOD: Elderly patients who underwent surgical treatment of intertrochanteric fractures in our hospital, from January 2018 to December 2020, were taken as the research object. According to the inclusion and exclusion criteria, a total of 76 patients were prospectively included and equally allocated to form a MDT group and a conventional group in this trial by the random number table method. The MDT was composed of doctors from nine disciplines, who would work jointly to evaluate the perioperative risk and formulate the treatment plan and the rehabilitation program. RESULTS: Compared with the conventional group, the time before weight-bearing (59.93 ± 5.93 days vs 67.93 ± 5.87 days), fracture healing time (68.98 ± 7.82 days vs 78.91 ± 7.09 days), and the length of hospital stay (10.43 ± 2.01 days vs 13.87 ± 2.13 days) in the MDT group were all shorter, P < 0.001, and the VAS declined from 3.18 ± 0.81 to 2.28 ± 0.87 at 3 days after the operation and from 0.26 ± 0.04 to 0.23 ± 0.03 at 3 months after the operation in the MDT group, P < 0.001. Compared with the only case in the MDT group which had postoperative complications, postoperative complications were more common in the conventional group, and the difference was statistically significant, P = 0.025. At 1 month and 1 year after the operation, the Harris hip score results of the MDT group were all higher in the seven aspects than those in the conventional group; the difference was statistically significant ( P < 0.001). CONCLUSION: The MDT participated in the perioperative management and the guidance of postoperative rehabilitation of elderly patients with intertrochanteric fractures can markedly improve perioperative symptoms, promote postoperative recovery, and improve long-term hip joint function.

Correlation between fat infiltration of paraspinal muscle and L4 degenerative lumbar spondylolisthesis in asymptomatic adults.

OBJECTIVE: To explore the relationship between different indicators of the degree of fat infiltration and L4 Degenerative lumbar spondylolisthesis (DLS). METHODS: 128 patients received annual health check-up underwent lumbar lateral Digital Radiography (DR) and abdominal Computed tomography (CT) imaging were enrolled. The DLS group included 60 patients diagnosed with DLS, and the control group included 68 patients without DLS. The data collected included vertebral density of L4-L5, fat infiltration ratio (FIR) of paravertebral muscle (PM) and psoas major muscle (PMM), skeletal muscle density of PM and PMM, low attenuation muscle ratio (LTR) of PM and PMM, paraspinal muscle density (PMD), psoas major muscle density (PMMD), low attenuation muscle density (LMD) of PM and PMM, facet joint angle (FJA), facet joint degeneration (FJD), etc. RESULTS: PM FIR and PM LTR were weakly positively correlated with the degree of L4 DLS, and there was a weak negative correlation between PMD and the degree of L4 DLS in asymptomatic adults (P < 0.05). Logistic regression analysis showed that PM FIR was an independent related factor of L4 DLS (Q3 vs. Q1, OR = 3.746, 95% CI: 1.076-13.048, p = 0.038). ROC curve analysis showed that the PM FIR has a high predictive value for L4 DLS in asymptomatic adults. CONCLUSION: The indicator of PM FIR was an independent related factor of L4 DLS in asymptomatic adults. It has a high predictive value for L4 DLS and can be applied as a potential target for clinical treatment of L4 DLS in asymptomatic adults.

Recent Advances in High-Mobility and High-Stretchability Organic Field-Effect Transistors: From Materials, Devices to Applications.

Stretchable organic field-effect transistors (OFETs) are one of the essential building blocks for next-generation wearable electronics due to the high stretchability of OFET well matching with the large deformation of human skin. In recent years, some significant progress of stretchable OFETs have already been made via the strategies of stretchable molecular design and geometry engineering. However, the main opportunity and challenge of stretchable OFETs is still to simultaneously improve their stretchability and mobility. This review covers the recent advances in the research of stretchable OFETs with high mobility. First, the core stretchable materials are summarized, including organic semiconductors, electrodes, dielectrics, and substrates. Second, the materials and healing mechanism of self-healing OFET are summarized in detail. Subsequently, their different configurations and the potential applications are summarized. Finally, an outlook of future research directions and challenges in this area is presented.
