Small molecule quinone compounds are attractive cathode materials for rechargeable aqueous zinc‐organic batteries (AZOBs) because of their structural diversity and low‐cost merits. Among them, nonpolar quinones are dominant given the relatively low solubilities in aqueous electrolytes. However, their poor electronic conductivity and accumulated Coulombic repulsion lead to underutilized active sites and sluggish redox kinetics. Here, polar 2,6‐dimethoxy‐1,4‐benzoquinone (m‐DMBQ) works as an advanced AZOB cathode with unexpectedly superior performance over the nonpolar isomer of 2,5‐dimethoxy‐1,4‐benzoquinone (p‐DMBQ). The asymmetric charge distribution of active centers in the p−π conjugated backbone of m‐DMBQ induces reduced bandgap with improved electronic conductivity and redox activity, thus achieving a high specific capacity of 312 mAh g−1 approaching the theoretical limit. Additionally, the lowest unoccupied molecular orbital energy level is lowered for an increased average discharge voltage of 0.88 V. Characterizations and computational studies revealed boosted competitiveness of H+ relative to Zn2+ for significantly enhanced charge transfer kinetics and reversibility. As a result, the as‐fabricated AZOB achieves a high energy density of 275 Wh kg−1 based on m‐DMBQ along with high‐rate capability and long‐term cycling stability. This work provides a new molecular engineering strategy through regulating charge distribution symmetry for boosting charge storage in organic cathodes. [ABSTRACT FROM AUTHOR]

Aim: To explore the role of missed nursing care in mediating the relationship between career calling and intention to leave among nurses. Introduction: Increasing nurse turnover is still a major concern in the global healthcare system. The most reliable indicator of turnover is turnover intention. It is crucial to understand its affecting elements to suggest measures to lower nurses' turnover intention. Background: Turnover intention has been linked to career calling and missed nursing care. Little empirical research has investigated the possibility that missed nursing care mediates between career calling and turnover intention. Methods: A cross‐sectional survey of 347 nurses was conducted. The survey instruments included the General Information Questionnaire, Calling Scale, Missed Nursing Care Scale and Turnover Intention Questionnaire. Structural equation models were used to build the model. This study made use of the STROBE checklist. Results: For 43.8% of nurses, turnover intention was high or very high. Missed nursing care and turnover intention were negatively correlated with career calling. Missed nursing care and turnover intention were positively related. Missed nursing care mediated the relationship between career calling and turnover intention. Discussion: Career calling and missed nursing care can both influence turnover intention. Career calling can reduce the likelihood of turnover by preventing missed nursing care. Conclusion: Missed nursing care mediated the relationship between career calling and intention to leave. Implications for nursing and nursing policy: Nursing managers should improve nurses' career calling through professional education and minimize missed nursing care by using electronic nursing reminder devices to reduce turnover intention.

The transmembrane glycoprotein adhesion molecule CD146 is overexpressed in a wide variety of cancers. CD146 expression constitutes a marker of poor prognosis and correlates with cancer progression. Through molecular imaging, a specific biomarker's expression and distribution can be viewed in vivo non‐invasively. Radionuclide‐labeled monoclonal antibodies or relevant fragments that target CD146 may find potential applications in cancer imaging, thereby offering tremendous value in cancer diagnosis, staging, prognosis evaluation, and prediction of drug resistance. This review discusses the recent developments of CD146‐targeted molecular imaging via nuclear medicine, especially in malignant melanoma, brain tumor, lung cancer, liver cancer, breast cancer, and pancreatic cancer. Many studies have proved that CD146 targeting may present a promising strategy for cancer theranostics. [ABSTRACT FROM AUTHOR]

Autism spectrum disorder (ASD) has a pronounced male predominance, but the underlying neurobiological basis of this sex bias remains unclear. Gender incoherence (GI) theory suggests that ASD is more neurally androgynous than same‐sex controls. Given its central role, altered structures and functions, and sex‐dependent network differences in ASD, the triple network model, including the central executive network (CEN), default mode network (DMN), and salience network (SN), has emerged as a candidate for characterizing this sex difference. Here, we measured the sex‐related effective connectivity (EC) differences within and between these three networks in 72 children with ASD (36 females, 8–14 years) and 72 typically developing controls (TCs) (36 females, 8–14 years) from 5 sites of the Autism Brain Imaging Data Exchange repositories using a 2 × 2 analysis of covariance factorial design. We also assessed brain‐behavior relationships and the effects of age on EC. We found significant diagnosis‐by‐sex interactions on EC: females with ASD had significantly higher EC than their male counterparts within the DMN and between the SN and CEN. The interaction pattern supported the GI theory by showing that the higher EC observed in females with ASD reflected a shift towards the higher level of EC displayed in male TCs (neural masculinization), and the lower EC seen in males with ASD reflected a shift towards the lower level of EC displayed in female TCs (neural feminization). We also found significant brain‐behavior correlations and significant effects of age on EC. Lay Summary: The triple network model offers a parsimonious framework for understanding autism spectrum disorder (ASD)‐related symptoms. Using functional brain imaging, our study revealed that effective connectivity showed a shift towards female typically developing controls (TCs) in males with ASD, whereas a shift towards male TCs in females with ASD, revealing a gender incoherence. These findings provide novel evidence for sex differences in ASD at the neurobiological level. [ABSTRACT FROM AUTHOR]

Frying is one of the most common methods of preparing foods. However, it may lead to the formation of potentially hazardous substances, such as acrylamide, heterocyclic amines, trans fatty acids, advanced glycation end products, hydroxymethyl furfural and polycyclic aromatic hydrocarbons, and adversely alter the desirable sensory attributes of foods, thereby reducing the safety and quality of fried foods. Currently, the formation of toxic substances is usually reduced by pretreatment of the raw materials, optimization of process parameters, and the use of coatings. However, many of these strategies are not highly effective at inhibiting the formation of these undesirable reaction products. Plant extracts can be used for this purpose because of their abundance, safety, and beneficial functional attributes. In this article, we focus on the potential of using plant extracts to inhibit the formation of hazardous substances, so as to improve the safety of fried food. In addition, we also summarized the effects of plant extracts, which inhibit the production of hazardous substances, on food sensory aspects (flavor, color, texture, and taste). Finally, we highlight areas where further research is required. [ABSTRACT FROM AUTHOR]

Fabrication of single‐crystalline organic semiconductor patterns is of key importance to enable practical applications. However due to the poor controllability on nucleation locations and the intrinsic anisotropic nature of single‐crystals, growth of single‐crystal patterns with homogeneous orientation is a big challenge especially by the vapor method. Herein a vapor growth protocol to achieve patterned organic semiconductor single‐crystals with high crystallinity and uniform crystallographic orientation is presented. The protocol relies on the recently invented microspacing in‐air sublimation assisted with surface wettability treatment to precisely pin the organic molecules at desired locations, and inter‐connecting pattern motifs to induce homogeneous crystallographic orientation. Single‐crystalline patterns with different shapes and sizes, and uniform orientation are demonstrated exemplarily by using 2,7‐dioctyl[1]benzothieno[3,2‐b][1]benzothiophene (C8‐BTBT). Field‐effect transistor arrays fabricate on the patterned C8‐BTBT single‐crystal patterns show uniform electrical performance: a 100% yield with an average mobility of 6.28 cm2 V−1 s−1 and in a 5 × 8 array. The developed protocols overcome the uncontrollability of the isolated crystal patterns in vapor growth on non‐epitaxial substrates, making it possible to align the anisotropic electronic nature of single‐crystal patterns in large‐scale devices integration.

This paper investigates the state interval estimation and fault detection (FD) problems for a Lipschitz nonlinear switched system based on the combination of the H∞$$ {H}_{\infty } $$ observer and the zonotope method. To begin with, an H∞$$ {H}_{\infty } $$ observer that is robust to the disturbance is designed, and the stability of the observer error dynamic system is analyzed under the average dwell time (ADT) concept. After this, the zonotope theory is applied on the H∞$$ {H}_{\infty } $$ observer error dynamic system such that the interval state estimation can be calculated iteratively when the system suffers from no fault. Furthermore, for FD purpose, a residual is constructed based on the H∞$$ {H}_{\infty } $$ observer. Because the constructed residual contains disturbance, it cannot be used for FD directly. To overcome this drawback, the interval estimation method of the residual is proposed by using the zonotope method, and a residual‐based FD scheme is developed. Finally, a simulation example is given to verify the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

The development of Mg‐ion batteries is hindered by the lack of cathode materials that allow facile and reversible Mg2+ intercalation at high potential. Herein, the authors present a polyanion cathode material of K2(VO)2(HPO4)2(C2O4)⋅4.5H2O (KVPCH) for Mg‐ion batteries. The inductive effect of polyanions ensures the high redox potential of the vanadium centers. In addition, the material contains structural water located between the layers. It helps with Mg2+ desolvation at the electrode–electrolyte interface and facilitates its diffusion in the structure, as confirmed by experimental analysis and theoretical calculations. Thanks to those factors, the KVPCH electrode presents excellent Mg storage capability at room temperature. It delivers 121 mAh g–1 capacity at 1C with a high average discharge potential of 0.16 V versus Ag/Ag+ (3.2 V vs Mg/Mg2+). A capacity retention of 87% is realized after 1500 cycles at 5C. A rocking‐chair Mg‐ion full cell is also demonstrated with the KVPCH cathode and a MoOx anode, which achieves 46 mAh g–1 capacity (based on the total active material mass of two electrodes). This work would bring effective paths for the design of cathode materials for Mg‐ion batteries. [ABSTRACT FROM AUTHOR]

Mn‐based materials for aqueous energy storage are reaching the capacity ceiling due to the limited Mn4+/Mn3+ redox. The disproportionation of Mn3+ often occurs, forming soluble Mn2+ and thus leading to severer capacity decays. Here, an amorphous manganese phosphate material [AMP, Na1.8Mn4O1.4(PO4)3] is fabricated using an electrochemical method for the first time. Benefitting from the open framework and the insoluble nature of Mn2+ in AMP, the Mn3+/Mn2+ and Mn4+/Mn3+ redox couples can participate in the charge storage processes. The AMP electrode shows a high capacity of 253.4 mAh g−1 (912.4 F g−1 or 912.4 C g−1) at the current density 1 A g−1 and good rate capability. Experimental results indicate AMP experiences a mixed charge storage mechanism (i.e., cation intercalation and conversion reactions) in Na2SO4 electrolyte. Besides, electrolyte engineering can effectively prevent the decomposition of AMP during cycling test, achieving capacity retention of 97% in 5000 cycles. Importantly, AMP can accommodate different cations (e.g., Mg2+, Ca2+, etc.), exhibiting great potential for aqueous energy storage. [ABSTRACT FROM AUTHOR]

Lymphoma is a heterogeneous disease with varying clinical manifestations and outcomes. Many subtypes of lymphoma, such as Burkitt′s lymphoma and diffuse large B cell lymphoma, are highly aggressive with dismal prognosis even after conventional chemotherapy and radiotherapy. As such, exploring specific biomarkers for lymphoma is of high clinical significance. Herein, a potential marker, CD38, is investigated for differentiating lymphoma. A CD38‐targeting monoclonal antibody (mAb, daratumumab) is then radiolabeled with Zr‐89 and Lu‐177 for theranostic applications. As the diagnostic component, the Zr‐89‐labeled mAb is highly specific in delineating CD38‐positive lymphoma via positron emission tomography (PET) imaging, while the Lu‐177‐labeled mAb serves well as the therapeutic component to suppress tumor growth after a one‐time administration. These results strongly suggest that CD38 is a lymphoma‐specific marker and prove that 89Zr/177Lu‐labeled daratumumab facilitates immunoPET imaging and radioimmunotherapy of lymphoma in preclinical models. Further clinical evaluation and translation of this CD38‐targeted theranostics may be of significant help in lymphoma patient stratification and management. [ABSTRACT FROM AUTHOR]

Developing cost‐effective and active catalysts for oxygen evolution reaction (OER) towards renewable energy‐related system, and applying the catalysts under both alkaline and acidic conditions is still a great challenge. In this work, a facile wet‐chemical method is reported to synthesize ultrafine IrxNiy alloy encapsulated in porous N‐doped carbon (BMNC) derived from bimetallic zeolitic imidazolate frameworks (ZIFs). Benefiting from the advantages of alloy effect between Ir and Ni, high surface area and more active site exposing, the optimal sample Ir3Ni2/BMNC with only 7.7 wt% Ir content reveals outstanding OER electrocatalytic activity in alkaline and acidic electrolyte. When evaluated in 1 m KOH, Ir3Ni2/BMNC exhibits low overpotential of 279 mV to drive current density of 10 mA cm−2 compared with IrO2 (322 mV), 59.4 times Ir mass activity of 303 A gIr−1 higher than IrO2 (5.1 AgIr−1) and prominent durability of 40 000 s for chronopotentiometry test. Assessed in 0.1 m HClO4, Ir3Ni2/BMNC also possesses long stability of 40 000 s for chronopotentiometry, high current density (η10 = 321 mV) and 19.9 times Ir mass activity (303 A gIr−1) superior to IrO2 of η10 = 350 mV and 15.2 A gIr−1, respectively. The brilliant durability attributes to the structure of alloy nanoparticles anchored in porous N‐doped carbon. [ABSTRACT FROM AUTHOR]

New evidences suggest that long non‐coding RNAs (lncRNAs) may play important roles in a variety of kidney diseases, including diabetic nephropathy (DN). Our present study investigated the potential function of LINC00462 in high glucose (HG)‐induced apoptosis of renal tubular epithelial cells (RTEC) and to determine the underlying mechanism. The expression of LINC00462 in renal biopsy tissues was examined using quantitative reverse‐transcription polymerase chain reaction (qRT‐PCR). Then, a loss of function assay was performed to determine the protective effect of LINC00462 in HG‐induced RTEC damage. In addition, the downstream signaling pathway of LINC00462 was also investigated. The qRT‐PCR results showed that the expression of LINC00462 was significantly up‐regulated in renal biopsies from DN patients. At the same time, LINC00462 was enhanced in a glucose concentration‐ and time‐dependent manner in human kidney (HK‐2 and HKC) cells subjected to HG treatment. The knockdown of LINC00462 improved the significantly reduced cell viability of HG treatment, decreased HG‐induced reactive oxygen species (ROS) and malondialdehyde levels, and up‐regulated the response of antioxidant systems to ROS by increasing superoxide dismutase and catalase levels. In addition, knockdown of LINC00462 inhibited HG‐induced cell apoptosis and affected the expression of apoptosis‐related proteins. Most importantly, we found that knockdown of LINC00462 enhanced the expression of p‐AKT. Moreover, AKT‐specific inhibitor LY294002 restored the effect of LINC00462 knockdown on apoptosis. In conclusion, our study demonstrated that knockdown of LINC00462 can ameliorate oxidative stress and apoptosis in HG‐induced RTEC by activating the AKT pathway, suggesting that knockdown of LINC00462 may provide a potential therapeutic approach for DN.

VOPO4⋅x H2O has been proposed as a cathode for rechargeable aqueous zinc batteries. However, it undergoes significant voltage decay in conventional Zn(OTf)2 electrolyte. Investigations show the decomposition of VOPO4⋅x H2O into VOx in the electrolyte and voltage drops after losing the inductive effect from polyanions.PO43− was thus added to shift the decomposition equilibrium. A high concentration of cheap, highly soluble ZnCl2 salt in the electrolyte further prevents VOPO4⋅x H2O dissolution. The cathode shows stable capacity and voltage retentions in 13 m ZnCl2/0.8 m H3PO4 aqueous electrolyte, in direct contrast to that in Zn(OTf)2 where the decomposition product VOx provides most electrochemical activity over cycling. Sequential H+ and Zn2+ intercalations into the structure are revealed, delivering a high capacity (170 mAh g−1). This work shows the potential issue with polyanion cathodes in zinc batteries and proposes an effective solution using fundamental chemical principles. [ABSTRACT FROM AUTHOR]

BACKGROUND: Proton‐exchange membrane (PEM) has a significant effect on the performance and overall cost of microbial fuel cells (MFCs). In this study, a novel composite PEM is fabricated by compositing sulfonated graphene oxide (SGO) with the Poly(vinylidene fluoride)‐g‐Poly(styrene sulfonic acid) (PVDF‐g‐PSSA) copolymer. The performance of MFCs with these newly prepared composite PEMs as separators was evaluated. A Quartz crystal microbalance with dissipation (QCM‐D) combined with membrane‐coated sensor crystals was used to investigate the biofouling mechanism of PEMs in MFCs at a micro‐perspective. RESULTS: The successful sulfonation of GO was confirmed by Fourier transform infrared spectrometry and X‐ray photoelectron spectroscopy. When the SGO loading was 1.0 wt%, the SGO/PVDF‐g‐PSSA membrane had higher water uptake (32.56%), proton conductivity (0.083 S cm−1) and excellent hydrophilicity (contact angle 70.78°) than that of Nafion 117. QCM‐D results further confirmed its better anti‐fouling property vs that of the PVDF‐g‐PSSA, GO/PVDF‐g‐PSSA, and Nafion 117 membranes. Moreover, the MFC working with the SGO/PVDF‐g‐PSSA membrane exhibited the highest maximum power density and best stability of power production after 3 months of operation. CONCLUSION: The SGO/PVDF‐g‐PSSA‐1.0 composite PEM can be used as an alternative material to Nafion in MFCs and is conducive to the long‐term stable operation of MFCs. © 2018 Society of Chemical Industry [ABSTRACT FROM AUTHOR]

A proton exchange membrane with low dimensional swelling and fuel crossover plays a critical role in improving the performance of fuel cells. Here, we present a facile way to overcome the high dimensional swelling and fuel crossover issues of the sulfonated poly (ether ether ketone) (SPEEK) membranes at a high ion exchange capacity (IEC) level by incorporation of sulfonated fully aromatic polyamide (S‐fa‐PA). A series of the S‐fa‐PA/SPEEK composite membranes (S‐fa‐PASPs) with various amount of the S‐fa‐PA were prepared. The influence of the S‐fa‐PA on thermal stability, mechanical stability, water uptake, dimensional swelling both in water and methanol aqueous solution, proton conductivity and methanol permeability was systematically investigated and compared. The excellent dimensional stabilities both in water and methanol aqueous solution of the S‐fa‐PASP membranes were obtained. The almost an order of magnitude lower methanol permeability than that of Nafion 117 was obtained for the S‐fa‐PASP membranes, suggesting that the study provides an effective approach for promoting the practical application of the SPEEK based membranes in DMFCs. Reduce the methanol permeability of the SPEEK membrane by using sulfonated fully aromatic polyamide (S‐fa‐PA) and improve the battery performance of the direct methanol fuel cell (DMFC) at high methanol concentrations [ABSTRACT FROM AUTHOR]

Low methanol permeability is one of the most critical factors for proton exchange membranes utilized in direct methanol fuel cells (DMFCs). Here, sulfonated poly(ether ether ketone) (SPEEK) polymer chains are interpenetrated into the semi‐interpenetrating polymer networks (semi‐IPNs) constructed by the alkylation reaction between bromobenzyl groups of bromomethylated poly(phenylene oxide) and amine groups of 2,2′‐(ethylenedioxy)bis(ethylamine) cross‐linker. The influences of crosslinking network contents on the key properties of SPEEK membranes are systematically investigated. Dimensional stability and methanol‐permeability resistance are enhanced as the increase of the crosslinking network contents. The relative selectivity is significantly improved due to the largely reduced methanol permeability. The DMFC assembled by the membrane with 20 wt.% crosslinking networks demonstrates four times higher power output than the Nafion 117 DMFC in 5 M methanol solution. SPEEK polymer chains are interpenetrated into the semi‐interpenetrating polymer networks with acid‐base ion pairs to improve dimensional stability and methanol‐permeability resistance. The DMFC assembled by the membrane with 20 wt.% crosslinking networks demonstrates four times higher power output than the Nafion 117 DMFC in 5 M methanol solution. [ABSTRACT FROM AUTHOR]

The adolescent brain is vulnerable to long‐lasting cognitive disturbances resulting from nicotine exposure. Although exercise has been used as an intervention for ameliorating cognitive deficits in various disorders, the effect on cognitive changes induced by nicotine exposure and its underlying mechanisms remain unclear. The purpose of this study was to investigate the effects of exercise on nicotine reward‐associated cognitive behaviors in adolescent rats subjected to nicotine conditioned place preference paradigm (CPP). Male adolescent rats were trained on the Go/NoGo task, then subjected to nicotine CPP, and then randomly separated into four groups: sedentary (SED), high‐ (HE), moderate‐ (ME), and low‐intensity (LE) exercise. Rats in exercise groups performed treadmill running 30 min daily for 10 days. Results showed that MEs had shorter escape latencies in the Morris water maze (MWM) test compared to SEDs. Although time spent and distance swam in the target quadrant significantly increased in both the MEs and HEs, the number of target quadrant crosses increased significantly only in MEs. MEs and HEs showed higher performance accuracy on NoGo and lower scores on CPP tasks. Expression of α7 nicotinic acetylcholine receptors (nAChRs) and downstream signaling molecules increased in MEs in prefrontal cortex but not hippocampus, with α7 nAChRs expression positively associated with NoGo accuracy and MWM probe test performance, but negatively correlated with CPP scores. The findings of this study suggest that moderate‐intensity exercise can improve nicotine induced cognitive behaviors, and implicates prefrontal cortical α7 nAChR‐mediated signal transduction as a possible mechanism.

Abstract: A polymer electrolyte with a particular molecular architecture plays a critical role in the improvement of the performances of both a polymer electrolyte and a battery device. Here, we present the design and synthesis of a sp3‐boron‐based single‐ion polymer electrolyte (SIPE), lithium poly(bisphenol AF borate) (LiPFB), by using partially aromatic bisphenol AF as a linker. As a result of the torsional, flexible, and strong electron‐withdrawing properties of the bistrifluoromethyl methylene group (−C(CF3)2−), the prepared poly(vinylidene fluoride‐co‐hexafluoropropene (PVDF‐HFP)/LiPFB membrane displays an enhanced ionic conductivity and a remarkable compatibility with electrodes compared to that of the PVDF‐HFP/lithium poly(4,4′‐biphenol borate) membrane, in which a linear and fully aromatic 4,4′‐biphenol is used as a linker. Consequently, an excellent battery performance both at room temperature and high charge/discharge rates was demonstrated. This study underscores the fundamental importance of the molecular structure of SIPE materials in battery performance enhancement and suggests ways to design new SIPE materials to enhance battery devices with improved electrochemical performance.

Abstract: The self‐assembly process between rigid fully aromatic single ion conducting polymer electrolytes (SIPEs) and flexible aliphatic binder for fabrication of macro‐scale porosity of membrane for enhancement of ionic conductivity has been demonstrated in our previous works. In this article, the bulky and rigid fluorene cardo groups are successfully introduced into the fully aromatic polymeric backbone to synthesize the fluorene‐containing cardo fully aromatic single ion conducting polymer electrolyte (fca‐SIPE). The synthesized fca‐SIPE is then blended with a flexible aliphatic PVDF‐HFP binder to prepare fca‐SIPE membrane via a solution cast method. By comparing with results of the previous works, in this case, not only the macro‐scale porous morphology derived from the self‐assembly process between PVDF‐HFP and fca‐SIPE, but also the interior nano‐scale lithium ion transport pathway throughout the free volume formed by the fluorene groups is obtained. The effect of the fluorene group on the key properties of membrane, such as ionic conductivity and battery performance, is systematically investigated. The excellent performance at high C‐rates at room temperature is demonstrated. [ABSTRACT FROM AUTHOR]

Aim: Over the past few decades, a large number of rural residents have migrated to cities in China and left their children behind. This study estimated how many 10- to 14-year-old children in rural Anhui drank alcohol and examined the association between parental migration and children's alcohol use.Methods: A cross-sectional study was conducted in six cities in Anhui between July and August 2012. All participants had lived in the study villages for at least six months during the previous year and were interviewed face-to-face using a standardised questionnaire.Results: More than half (57%) of the 1367 subjects were left-behind children, 43% lived with both parents and 9.6% currently drank alcohol. When we controlled for other variables, the rate of alcohol use was statistically higher among left-behind children if both parents had migrated (14.0%) than among children living with both parents (7.8%) (p = 0.002). Boys, children with siblings and those with a poorer academic performance were more likely to drink.Conclusion: Children in rural China were more likely to drink if both their parents had migrated in search of work. School-based interventions could help to reduce alcohol use among rural left-behind children, especially boys. [ABSTRACT FROM AUTHOR]

Objective The primary objectives of this rapid assessment were to assess the clinical evidence of Da Vinci surgical system (DVSS) comparing with open procedures and laparoscopic procedures, and in order to provide the evidence for health decision makers and clinician. Methods A comprehensive search of electronic databases (EMbase, PubMed, The Cochrane Library, Web of Science, CNKI, VIP, CBM and Wanfang) and HTA websites were completed up to 9 October, 2013. Two reviews (Jiajie Yu and Yingqiang Wang) independently extracted data of the manuscripts, and assessed quality of included studies using AMSTAR tools. Qualitative description and GRADE were used to report the outcomes and evidence quality. Outcomes A total of 17 studies were included: 3 were HTA and 14 were SR/meta-analysis. The included studies focused on prostatectomy, nephrectomy, hysterectomy colorectal surgery, and cardiac surgery. DVSS was shown to be associated with statistically significant reduction in length of hospital stay, blood loss, and transfusion rate compared with open and laparoscopic surgery, but increase in operative time when compared with open surgery. Conclusion Based on the evidence included in this rapid assessment, DVSS has a limited impact on several clinical outcomes. Considering no available data from randomized controlled trials and much higher cost, decisions will be complex and need to be made carefully. Decision makers should cut down the quantity of purchasing and reasonable allocate them. [ABSTRACT FROM AUTHOR]

Herein, a novel electrospun single‐ion conducting polymer electrolyte (SIPE) composed of nanoscale mixed poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) and lithium poly(4,4′‐diaminodiphenylsulfone, bis(4‐carbonyl benzene sulfonyl)imide) (LiPSI) is reported, which simultaneously overcomes the drawbacks of the polyolefin‐based separator (low porosity and poor electrolyte wettability and thermal dimensional stability) and the LiPF6 salt (poor thermal stability and moisture sensitivity). The electrospun nanofiber membrane (es‐PVPSI) has high porosity and appropriate mechanical strength. The fully aromatic polyamide backbone enables high thermal dimensional stability of es‐PVPSI membrane even at 300 °C, while the high polarity and high porosity ensures fast electrolyte wetting. Impregnation of the membrane with the ethylene carbonate (EC)/dimethyl carbonate (DMC) (v:v = 1:1) solvent mixture yields a SIPE offering wide electrochemical stability, good ionic conductivity, and high lithium‐ion transference number. Based on the above‐mentioned merits, Li/LiFePO4 cells using such a SIPE exhibit excellent rate capacity and outstanding electrochemical stability for 1000 cycles at least, indicating that such an electrolyte can replace the conventional liquid electrolyte–polyolefin combination in lithium ion batteries (LIBs). In addition, the long‐term stripping–plating cycling test coupled with scanning electron microscope (SEM) images of lithium foil clearly confirms that the es‐PVPSI membrane is capable of suppressing lithium dendrite growth, which is fundamental for its use in high‐energy Li metal batteries. A novel electrospun single‐ion conducting polymer electrolyte (SIPE) is reported in this research paper, offering wide electrochemical stability, good ionic conductivity, high lithium‐ion transference number, and superior cell performance. SIPE is capable of suppressing lithium dendrite growth, possibly enabling its use in high‐energy Li metal batteries. [ABSTRACT FROM AUTHOR]
