Background: In the early postoperative stage after heart transplantation, there is a lack of predictive tools to guide postoperative management. Whether the vasoactive-inotropic score (VIS) can aid this prediction is not well illustrated. Methods: In total, 325 adult patients who underwent heart transplantation at our center between January 2015 and December 2018 were included. The maximum VIS (VISmax) within 24 h postoperatively was calculated. The Kaplan-Meier method was used for survival analysis. A logistic regression model was established to determine independent risk factors and to develop a nomogram for a composite severe adverse outcome combining early mortality and morbidity. Results: VISmax was significantly associated with extensive early outcomes such as early death, renal injury, cardiac reoperation and mechanical circulatory support in a gradedependent manner, and also predicted 90-day and 1-year survival (p < 0.05). A VIS-based nomogram for the severe adverse outcome was developed that included VISmax, preoperative advanced heart failure treatment, hemoglobin and serum creatinine. The nomogram was well calibrated (Hosmer-Lemeshow p = 0.424) with moderate to strong discrimination (C-index = 0.745) and good clinical utility. Conclusion: VISmax is a valuable prognostic index in heart transplantation. In the early post-transplant stage, this VIS-based nomogram can easily aid intensive care clinicians in inferring recipient status and guiding postoperative management. [ABSTRACT FROM AUTHOR]

Background The global prevalence of low back pain is gradually increasing, and it is the main cause of disability, sick leave, and unemployment, posing a heavy burden on individuals and society. Assessing the degree of disability in patients with chronic low back pain is crucial for evaluating the efficacy of clinical interventions and clinical epidemiology. The Roland-Morris Disability Questionnaire (RMDQ) is currently the main tool for evaluating disability in patients with low back pain, but the applicability of its measurement performance in the Chinese population remains unclear. Objective To evaluate the applicability of RMDQ in the Chinese population with low back pain and provide evidence for clinical practice and research application. Methods CNKI, Wanfang Data Knowledge Service Platform, SinoMed, PubMed, Embase and Web of Science were searched from inception to 2023-10-01, to establish a literature base for the performance of the low back pain scale, and then select research on the measurement performance of RMDQ from it. The measurement performance of the RMDQ scale was evaluated according to the COSMIN system evaluation guidelines, and the evidence evaluation level was used to grade the evidence. Results A total of six RMDQ documents were included, with insufficient methodological quality for RMDQ content validity and adequate measurement performance. The quality of internal consistency methodology was very good with uncertainty and measurement performance was adequate; the methodological quality of retesting was uncertain, and the measurement performance was sufficient; the methodological quality of measurement error was uncertain, and the measurement performance was sufficient; the methodological quality of criterion validity was uncertain, and the measurement performance was insufficient; hypothesis testing methodological quality was very good with uncertain, and the measurement performance was sufficient and uncertain; the quality of reactivity methodology was very good, with sufficient and insufficient, while the measurement performance was sufficient with insufficient. According to the GRADE evidence quality rating results, there is low quality evidence to prove uncertainty in content validity, and moderate quality evidence to prove sufficient retesting reliability and internal consistency; there is sufficient evidence of low quality to prove the measurement error and reactivity. There is very low quality evidence of insufficient calibration validity when using the Oswestry Dysfunction Index (ODI) and the Visual Analog Scale (VAS) as calibrators; hypothesis testing had moderate quality evidence of uncertainty. Conclusion The methodological quality of the RMDQ scale is not high, with acceptable measurement performanceand low quality of evidence, and needs to be used cautiously in clinical practice or trials of low back pain in China. Although there is sufficient evidence of moderate quality to prove the reliability and internal consistency of retesting, the research content and methods are not standardized. In future research, attention should be paid to standardization to more accurately assess its applicability in the Chinese population.

Newcastle disease (ND) and infectious bursal disease (IBD) are both one of the most economically important infectious diseases, which cause high infection rate and mortality of chickens and restrict the development of the poultry industry. Currently, vaccination is the most effective method to prevent ND and IBD. In this study, the biological adjuvant bivalent vaccine (rClone30- VP2L-chGM-CSF) was developed for preventing ND and IBD. Furthermore, the immune and protective effects of rClone30- VP2L-chGM-CSF were evaluated in specific-pathogen-free chickens. The experimental results indicated that chickens immunized with rClone30-VP2L-chGM-CSF vaccine significantly improved anti-IBDV and anti-NDV antibody titer; the level of CD4+ T, CD8+ T, B+, MHC-II+, and monocyte/macrophagocyte+ cells; the concentrations of IL-1β, IL-4, IL-17, IFN-α, IFN-β, and IFN-γ; and the splenocyte proliferation rate. Anti-NDV antibody titer reached the theoretical protection value of 4log2 at 7 days after immunization in chickens of rClone30-VP2L-chGM-CSF group; however, which at 14 days after immunization in chickens of rClone30-VP2L and rClone30. These results showed that chickens immunized with rClone30-VP2L-chGM-CSF stimulated stronger immune response than those with the rClone30-VP2L and rClone30. Chickens were challenged with virulent IBDV BC6/ 85, which were protected in the rClone30-VP2L-chGM-CSF group. Furthermore, IBDV RNA was not measured, and there appeared to be little apoptosis in the bursa of Fabricius in the rClone30-VP2L-chGM-CSF group. Therefore, rClone30-VP2L-chGM-CSF is a promising vaccine candidate against infectious bursal disease virus (IBDV) and newcastle disease virus (NDV), and it provides an idea for developing other poultry vaccines.

A plasma jet (a high temperature jet formed by blowing a free arc through high pressure air) method based on free arc was carried out to disperse carbon nanotubes (CNTs) in gas phase while generating Pt nanoparticles (Pt-NPs) on them at the same time. The plasma jet is generated through the discharge between the cathode composed of CNTs, PtCl 4 and DI water and the anode with a hole. Plasma jet prepares the Pt/CNT catalyst by directly spraying. The CNT carrier in the catalyst have good dispersion by SEM images. The mean size of Pt-NPs estimated by TEM images is 3.41 nm with the plasma jet method and about 4.77 nm with the commercial Pt/C respectively. It was showed that the bulk of Pt-NPs produced by plasma jet is in metal state in the analysis of XPS measurements. Compared with Pt/C, Pt/CNT have roughly equal catalytic activity and higher durability by cyclic voltammetry measurements. Based on these properties, the plasma injection method solves the problems of carrier dispersion and metal particle preparation at the same time, which greatly simplifies the catalyst preparation process. Plasma jet structure and process based on free arc. [Display omitted] • A plasma jet method based on free arc was carried out to disperse carbon nanotubes (CNTs) in gas phase and produce Pt nanoparticles (Pt-NPs) on them at the same time. The plasma jet is generated through the discharge between the cathode composed of CNTs, PtCl 4 and ID water and the anode with a hole. Plasma jet prepares the Pt/CNT catalyst by directly spraying. • The method of preparing transparent and conductive FLM through free arc dispersion of carbon nanotubes and hot pressing bonding is suitable for thin films and composite materials, and has achieved good results. In this work, we continue to explore and discover that while the free arc disperses carbon nanotubes, it can also reduce platinum ions and form platinum nanoparticles (Pt NP) on the surface of carbon nanotubes, ultimately preparing Pt/CNT catalysts. • The self-made device is composed of movable and automatically replenished CNTs cathode and a cooled conical tungsten anode. The formula of CNT Cathode used in CNT-Open and CNT-Jet is the same: 18.4 wt% CNTs, 7.95 wt% PtCl4, 73.6 wt% ID water. • The average particle size of Pt-NPs prepared by plasma jet method is 3.41nm, which is smaller than 4.77nm of commercially available catalysts. ADT shows that Pt/CNT has better durability, which means that CNT and Pt-NP have stronger interactions under the action of free arc. [ABSTRACT FROM AUTHOR]
