Construction and application of an ICU nursing electronic medical record quality control system in a Chinese tertiary hospital: a prospective controlled trial.

BACKGROUND: ICU nurses provide critical care and meticulously document electronic medical records (EMRs), tracking vital signs, interventions, and medication hourly. Despite China's ICUs effectively integrating real-time monitor and ventilator data into EMRs, challenges persist. Patient movements can introduce inaccuracies, and the demands of critical care may lead nurses to miss assessments like pain and nutrition. Traditional manual EMR verification is inefficient and error-prone, highlighting the urgent need for standardized, technology-aided EMR practices in ICU nursing. OBJECTIVE: This study aimed to describe the development and evaluation of an electronic medical records quality control system implemented in a Chinese tertiary care ICU setting, where current practices impact the accuracy of electronic medical records. METHODS: A prospective controlled trial was conducted with 600 ICU patients in Zhejiang Province from January to December 2023. An automated EMR quality control system was implemented in July 2023, facilitating real-time data collection and quality control for vital signs, medication management, and nursing evaluations. RESULTS: After implementing the ICU nursing electronic medical record quality control system, the prevalence of false data on vital signs decreased from 9 to 1.33%. Additionally, the incidence of incomplete medication administration dropped from 3.33 to 1.67%, and the rate of missing evaluations of assessment items in EMRs was reduced from 8 to 1.33%. Besides, the average time spent on quality control of the electronic medical records was 62 (48,76) seconds per record, which was significantly lower than the 264 (195.5,337.5) seconds using the traditional method. The nurses' satisfaction with the nursing electronic medical record quality control was (105.73 ± 9.31). CONCLUSIONS: The ICU nursing electronic medical record quality control system has led to substantial improvements in the quality and reliability of EMRs. The reduction in false data on vital signs, instances of incomplete medication administration, and missing evaluations of assessment items demonstrates the system's positive impact on nursing documentation practices. These improvements not only enhance the accuracy of patient records but also contribute to better patient care and safety within the ICU setting.

Precycling Strategy in Suitable Voltage to Improve the Stability of Interfacial Film and Suppress the Decline of LiNi0.6Mn0.2Co0.2O2 Cathode at Elevated Temperatures.

Layered ternary oxide LiNixMnyCo1-x-yO2 is a promising cathode candidate for high-energy lithium-ion batteries (LIBs). However, the capacity of LIBs is significantly restricted by several factors, including the repeated dissolution-regeneration of the interfacial film at high temperatures, the dissolution of transition metals, and the increase of impedance. Herein, a new precycling strategy in suitable voltage scope at room temperature is proposed to construct a uniform, thermally stable, and insoluble cathode-electrolyte interface (CEI), which helps to maintain stable cycling performances at high temperatures. Specifically, after 5 precycles in the range of 3.85-4.3 V at room temperature, a CEI layer containing numerous inorganic components and oligomers is formed on the surface of LiNi0.6Mn0.2Co0.2O2. Subsequently, the harmful side reactions are effectively suppressed, endowing the cell with an excellent capacity retention of 84.67% after 50 cycles at 0.5C and 55 °C, much higher than that of 65.61% under the conventional film-forming process conditions. This work emphasizes the crucial role of the precycling strategy in regulating the characteristics of CEI layer on the surface of cathode electrode, opening up a new avenue for the high-temperature application of positive electrodes of LIBs.

Panaxadiol carbamate derivatives: Synthesis and biological evaluation as potential multifunctional anti-Alzheimer agents.

It is reported that panaxadiol has neuroprotective effects. Previous studies have found that compound with carbamate structure introduced at the 3-OH position of 20 (R) -panaxadiol showed the most effective neuroprotective activity with an EC50 of 13.17 µM. Therefore, we designed and synthesized a series of ginseng diol carbamate derivatives with ginseng diol as the lead compound, and tested their anti-AD activity. It was found that the protective effect of compound Q4 on adrenal pheochromocytoma was 80.6 ±â€¯10.85 % (15 µM), and the EC50 was 4.32 µM. According to the ELISA results, Q4 reduced the expression of Aß25-35 by decreasing ß-secretase production. Molecular docking studies revealed that the binding affinity of Q4 to ß-secretase was -49.67 kcal/mol, indicating a strong binding affinity of Q4 to ß-secretase. Western blotting showed that compound Q4 decreased IL-1ß levels, which may contribute to its anti-inflammatory effect. Furthermore, compound Q4 exhibits anti-AD activities by reducing abnormal phosphorylation of tau protein and activation of the mitogen activated protein kinase pathway. The learning and memory deficits in mice treated with Q4in vivo were significantly alleviated. Therefore, Q4 may be a promising multifunctional drug for the treatment of AD, providing a new way for anti-AD drugs.

PET/MRI in Endometrial Cancer: Imaging Biomarkers are Associated with Disease Progression and Overall Survival.

RATIONALE AND OBJECTIVES: To evaluate the association between positron emission tomography (PET)/magnetic resonance imaging (MRI) biomarkers and survival outcomes in patients with endometrial cancer. MATERIALS AND METHODS: Between April 2014 and April 2016, 88 patients with newly diagnosed endometrial cancer participated this prospective study and underwent [18F] fluorodeoxyglucose PET/MRI. Sixty-nine patients with measurable tumors on PET/MRI were included in the image analysis. Imaging biomarkers included the minimum and mean apparent diffusion coefficients (ADCmin and ADCmean), maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) of the primary tumors. The log-rank test and Cox proportional hazards model were used to assess the relationship between imaging biomarkers and survival. RESULTS: After a median follow-up of 80 months, 15 (22%) patients had tumor progression and six (9%) patients died. The results of ADCmin, ADCmean, and SUVmax did not show a significant association with progression-free survival (PFS) and overall survival (OS). Significantly shorter PFS was noted in patients with primary tumors with higher MTV (P < 0.001) and TLG (P < 0.001). Significantly shorter OS was also noted in patients with primary tumors with higher MTV (P = 0.048) and TLG (P = 0.034). In the multivariate analysis, MTV was an independent predictor of PFS (hazard ratio = 10.84, P = 0.033). CONCLUSION: PET/MRI biomarkers, particularly MTV and TLG, are associated with PFS and OS in patients with endometrial cancer. MTV was an independent predictor of PFS.

Exposure or pandemic effect: Export boom in instant noodles from South Korea during COVID-19.

Amid the pandemic, it is crucial to comprehend both people's preferred food choices and the factors influencing food consumption. This understanding not only guarantees a stable food supply but also plays a pivotal role in economic recovery during times of recession. In 2020, South Korean instant noodles experienced an unprecedented surge in exports, catapulting the nation to the forefront of the global instant noodle market. The surge in the popularity of instant noodles during the pandemic can be partly attributed to their unique characteristics. However, the South Korean film Parasite, which garnered global acclaim around the same time, prominently featured instant noodle products. This exposure led to an extraordinary increase in internet searches for Korean-brand instant noodles. Therefore, this study utilized an interrupted time series model to investigate whether the surge in South Korean instant noodle exports was primarily a result of the 2019 coronavirus pandemic or the influence of the film. Our estimations indicate that the film's exposure effect predominantly explains the export boom of South Korean instant noodles.

Design, synthesis fusidic acid derivatives alleviate acute lung injury via inhibiting MAPK/NF-κB/NLRP3 pathway.

Acute lung injury (ALI) refers to a series of lung lesions resulting from multiple lung injuries, even leading to morbidity and death, abundant previous reports have showed that anti-inflammatory as a key to treatment of ALI. Fusidic acid (FA) as an antibiotic has significant anti-bacterial activity and anti-inflammatory effects. In this study, we designed and synthesized 34 FA derivatives to identify new anti-inflammatory drugs. The anti-inflammatory activities of the derivatives were screened using lipopolysaccharide (LPS)-induced RAW264.7 cells to evaluate the anti-inflammatory activity of the compounds, we measured nitric oxide (NO) and interleukin-6 (IL-6). Most of compounds showed inhibitory effects on inflammatory NO and IL-6 in LPS-induced RAW264.7 cells. Based on the screening results, compound a1 showed the strongest anti-inflammatory activity. Compared with FA, the inhibition rate NO and IL-6 of compound a1 increased 3.08 and 2.09 times at 10 µM, respectively. We further measured a1 inhibited inflammatory factor NO (IC50 = 3.26 ± 0.42 µM), IL-6 (IC50 = 1.85 ± 0.21 µM) and TNF-α (IC50 = 3.88 ± 0.55 µM). We also demonstrated that a1 markedly inhibits the expression of certain immune-related cytotoxic factors, including cyclooxygenase-2 (COX-2) and inducible nitric-oxide synthase (iNOS). In vivo results indicate that a1 can reduce lung inflammation and NO, IL-6, TNF-α, COX-2 and iNOS in LPS-induced ALI mice. On the one hand, we demonstrated a1 inhibits the mitogen-activated protein kinase (MAPK) signaling pathway by down-regulating the phosphorylation of p38 MAPK, c-Jun N-terminal kinase (c-JNK) and extracellular signal-regulated kinase (ERK). Moreover, a1 also suppressing the phosphorylation of inhibitory NF-κB inhibitor α (IκBα) inhibits the activation of the nuclear factor-κB (NF-κB) signaling pathway. On the other hand, we demonstrated a1 also role in anti-inflammatory by inhibits nucleotide-binding domain (NOD)-like receptor protein 3 (NLRP3) inflammasome and further inhibits Caspase-1 and inflammatory factor interleukin-1ß (IL-1ß). In conclusion, our study demonstrates that a1 has an anti-inflammatory effect and alleviates ALI by regulating inflammatory mediators and suppressing the MAPK, NF-κB and NLRP3 inflammasome signaling pathways.

Inhibition of transition-metal dissolution with an inert soluble product interface constructed by high-concentration electrolyte.

The formation of a compact and stable cathode electrolyte interphase (CEI) film is a promising way to improve the high voltage resistance of lithium-ion batteries (LIBs). However, challenges arise due to the corrosion of hydrogen fluoride (HF) and the dissolution of transition metal ions (TMs) in harsh conditions. To address this issue, researchers have constructed an anion-derived CEI film enriched with LiF and LiPO2F2 soluble product on the surface of LiNi0.5Mn1.5O4 (LNMO) cathode in highly concentrated electrolytes (HCEs). The strong binding of LiF and LiPO2F2 generated an inert LiPO2F2 soluble product interface, which inhibited HF corrosion and maintained the spinel structure of LNMO, contributing to a capacity retention of 92% after 200 cycles at 55°C in the resulting cell with a soluble LiPO2F2-containing CEI film. This new approach sheds light on improving the electrode/electrolyte interface for high-energy LIBs.

Improving performances of the electrode/electrolyte interface via the regulation of solvation complexes: a review and prospect.

The electrode/electrolyte interface (EEI) is a research hotspot in lithium-ion batteries, while the electrolyte solvation complex can be regarded as a factor that cannot be ignored in determining the performance of the EEI. From the perspective of the electrolyte solvation complex, this review summarizes the effects of solvation complexes on the composition of an EEI film and the Li+ desolvation process, and further clarifies the internal mechanism of the electrolyte composition controlling solvation chemistry. Finally, combined with doubtful points that are not comprehensively considered in the regulation of solvated complexes, this review puts forward some cutting-edge views, which are of great significance for future guidance in improving the performance of lithium-ion batteries.

In vitro and in vivo biological evaluation of newly synthesized multi-target 20(R)-panaxadiol derivatives for treating Alzheimer's disease.

An extensive study was performed to discover a series of novel 20(R)-panaxadiol derivatives with various substituents at the 3-OH position as nontoxic, brain-permeable, multi-target leads for treating Alzheimer's disease. In vitro analysis revealed that a compound bearing benzyl-substituted carbamate, which we denoted compound 14a, exhibited the most potent neuroprotective activity, with an EC50 of 13.17 µM. The neuroprotective effect of compound 14a was slightly more potent than that of donepezil and much more potent than that of 20(R)-panaxadiol. Compound 14a at 7.5-120 µM exhibited low toxicity in various cell lines. In addition, compound 14a exhibited a wide range of biological activities, including inhibiting apoptosis; inducing tau hyperphosphorylation; affecting beta-amyloid (Aß), ß-secretase, reactive oxygen species, tumor necrosis factor-α, cyclooxygenase-2, and interleukin-1ß production; and promoting Aß25-35 disaggregation. The effective permeability of compound 14a across the blood-brain barrier was 26.13 × 10-6 cm/s, indicating that it can provide adequate exposure in the central nervous system. Further, compound 14a improved learning, memory, and novel object recognition in mice, and in vivo toxicity experiments confirmed a good therapeutic safety range. Thus, compound 14a is a promising multifunctional lead for treating Alzheimer's disease and offers new avenues for natural product-derived anti-Alzheimer's disease drugs.

Optimizing the composition of LiFSI-based electrolytes by a method combining simplex with normalization.

The optimizing method of electrolyte formulation is always vital for the development of high-performance lithium-ion batteries. Traditional optimization methods are mainly aimed at the optimization of the electrolyte composition type, and less attention is paid to the optimization of the composition proportion in a certain electrolyte formulation. In this paper, in order to balance the relationship between aluminum (Al) foil corrosion inhibition and battery electrochemical performance, the electrolyte system LiFSI0.6-LiBOB0.4-EC/DEC/EMC (1 : 1 : 1, by volume) was optimized by combining the simplex method, normalization and electrochemical testing. A lithium iron phosphate (LiFePO4) cathode with the optimized electrolyte of LiFSI0.53-LiBOB0.35-EC/DEC/EMC (1.3 : 1.5 : 1.5) delivers a high capacity (143.1 mA h g-1 at 0.5C) and remarkable cycle life (94.9% retention after 100 cycles) at 45 °C. The outstanding performance is attributed to the composition of the cathode electrolyte interphase (CEI) containing the solid and dense LiF, AlF3, B2O3 and Li2CO3. This provides a new method and idea for future electrolyte formulation optimization.

Rarely occurring naturally, 1 is 2-methoxybenzofuranone type compound against α-glucosidase and exhibits a potential inhibitory effect on α-glucosidase(IC50 = 1.8 µM), with a Ki value of 709 nM. In silico molecular docking was performed for the investigation of the inhibition mechanism. H. erythrostictum is a potential source of antidiabetic agent. This information is useful in finding more potent antidiabetic candidates from medicinal plants for the clinical development of therapeutics.

[Assessment of Medical Waste Disposal Technologies Based on the AHP].

Five types of medical waste disposal technologies that are currently applied in our country were analyzed and compared such as the rotary kiln incineration method, pyrolysis method, high-temperature steam sterilization method, chemical disinfection method, and microwave disinfection method. The five methods were quantitatively evaluated and screened using an analytical hierarchy process (AHP). Based on this process, the ranking weights of optimal and suboptimal alternatives were studied using sensitivity analysis. The results show that the rotary kiln incineration and pyrolysis methods are presently the most widely used technologies for medical waste disposal in our country. The AHP shows that the comprehensive benefits of high-temperature steam sterilization in medical waste disposal are the best compared with the other four methods in terms of social, environmental, technological, and economic factors, followed by the chemical disinfection method. The sensitivity analysis shows that the change points of the guideline layer factors that lead to the change of the alternatives are the social factors (0.2100), environmental factors (0.3500), technical factors (0.1200), and economic factors (0.2400). Subcriteria factors have less influence on the weight ranking of the alternatives.

The infection of Mycoplasma hominis after total knee replacement: Case report and literature review.

The Mycoplasma hominis infection is a rare postoperative complication after joint replacement. Based on our knowledge, there were only two cases reported by Korea all over the world currently. A case of postoperative Mycoplasma hominis infection after total knee replacement in our hospital was reported in this article. It was confirmed through mass spectrometer and Mycoplasma cultivation and treated by the first stage debridement, polyethylene insert replacement, and then drainage and irrigation combined with sensitive antibiotics after the operation. We observed that the C reactive protein (CRP) level correlates with the development of disease, while the erythrocyte sedimentation rate (ESR) remains at a high level, indicating the relevance between the Mycoplasma hominis infection caused by knee joint replacement and CRP. This study aims to report the case and review relevant literature.

Passivity analysis for memristor-based recurrent neural networks with discrete and distributed delays.

In this paper, based on the knowledge of memristor and recurrent neural networks (RNNs), the model of the memristor-based RNNs with discrete and distributed delays is established. By constructing proper Lyapunov functionals and using inequality technique, several sufficient conditions are given to ensure the passivity of the memristor-based RNNs with discrete and distributed delays in the sense of Filippov solutions. The passivity conditions here are presented in terms of linear matrix inequalities, which can be easily solved by using Matlab Tools. In addition, the results of this paper complement and extend the earlier publications. Finally, numerical simulations are employed to illustrate the effectiveness of the obtained results.

Identification and expression profiles of nine glutathione S-transferase genes from the important rice phloem sap-sucker and virus vector Laodelphax striatellus (Fallén) (Hemiptera: Delphacidae).

BACKGROUND: Glutathione S-transferases (GSTs) have received considerable attention in insects for their roles in insecticide resistance. Laodelphax striatellus (Fallén) is a serious rice pest. L. striatellus outbreaks occur frequently throughout eastern Asia. A key problem in controlling this pest is its rapid adaptation to numerous insecticides. In this research, nine cDNAs encoding GSTs in L. striatellus were cloned and characterised. RESULTS: The cloned GSTs of L. striatellus belonged to six cytosolic classes and a microsomal subgroup. Exposure to sublethal concentrations of each of the six insecticides, DDT, chlorpyrifos, fipronil, imidacloprid, buprofezin and beta-cypermethrin, quickly induced (6 h) up-expression of LsGSTe1. The expression of LsGSTs2 was increased by chlorpyrifos, fipronil and beta-cypermethrin. Furthermore, exposure of L. striatellus to fipronil, imidacloprid, buprofezin and beta-cypermethrin increased the expression of the LsGSTm gene after 24 or 48 h. CONCLUSION: This work is the first identification of GST genes from different GST groups in Auchenorrhyncha species and their induction characteristics with insecticide types and time. The elevated expression of GST genes induced by insecticides might be related to the enhanced tolerance of this insect to insecticides and xenobiotics.

In the title coordination polymer, {[Zn(C(11)H(15)O(3))(2)(C(10)H(8)N(2))(C(11)H(16)O(3))]·H(2)O}(n), the Zn(II) ion is five coordinated by two N atoms from two 4,4'-bipyridine (4,4'-bpy) mol-ecules and three O atoms from two 3-hy-droxy-adamantane-1-carboxyl-ate anions (L) and one 3-hy-droxy-adamantane-1-carb-oxy-lic acid (HL) mol-ecule. The resulting coordination polyhedron is a near regular ZnN(2)O(3) trigonal bipyramid, with the N atoms in axial sites. The 4,4'-bpy mol-ecules [dihedral angle between the aromatic rings = 17.2 (2)°] act as bridges, connecting the metal ions into an infinite polymeric chain propagating in [[Formula: see text]01]. O-H⋯O hydrogen bonds help to consolidate the packing.

Comparison of interface contact profiles of a new minimum contact locking compression plate and the limited contact dynamic compression plate.

In this study, we investigated whether or not a new minimum contact locking compression plate (MC-LCP) can provide advantages over the limited contact dynamic compression plate (LC-DCP) in the context of interface contact area and force. Six matched pairs of cadaveric bones were used for each of three bone types of the humerus, radius and ulna. For each bone type, one of two bone plates was fixed to either of two matched cadaveric bones at the middle of the diaphysis. The interface contact area and force of the plate fixed to three types of human cadaveric bones were evaluated using Fuji prescale pressure sensitive film. Data were quantitated using computer-assisted image analysis. Results showed that the average force between the MC-LCP and humerus or radius was about half of that of the LC-DCP. And the average force between the MC-LCP and ulna was one third less than that of the LC-DCP. Meanwhile, the interface contact area between the MC-LCP and humerus or radius was also about half of that of the LC-DCP, and the interface contact area between the MC-LCP and ulna was less than one third of that of the LC-DCP. These results indicate that the MC-LCP has lower interface contact area and lower average force than that of the LC-DCP. Thus, the MC-LCP system may be a good alternate to treat forearm diaphyseal fractures.

[The comparative study of patients with severe polytrauma treated by damage control orthopedits in normal time and in earthquake].

OBJECTIVE: To compare the outcome of damage control in patients with severe polytrauma in normal time and in the earthquake of 2008 Sichuan China. METHODS: In the retrospective study, 26 cases with severity polytrauma in peacetime and 24 cases with severe polytrauma who have mainly sustained in the earthquake of 2008 Sichuan China were involovd. The patients' demographics, the methods and effects of damage control were evaluated. RESULTS: In the earthquake group, 24 cases succeeded in the rescuing life; among whom, 3 patients needed the further debridement and dermoplasty. In the normal time group, 26 cases succeeded in the rescuing life; among whom, 19 patients had returned to their former work and 3 patients needed the further treatment. There was no difference between two groups in therapeutic effects (P > 0.05). CONCLUSION: Both in earthquake and in normal time, treating the severity polytrauma by damage control orthopedics can acquire satisfied effect.

Damage control orthopaedics in 53 cases of severe polytrauma who have mainly sustained orthopaedic trauma.

OBJECTIVE: To discuss damage control orthopaedics in 53 cases of severe polytrauma who have mainly sustained orthopaedic trauma. METHODS: The data of 53 cases of severe polytrauma who had mainly sustained orthopaedic trauma were retrospectively analyzed. And the methods and timing of damage control orthopaedics were discussed in this study. RESULTS: We succeeded in rescuing the lives of all the 53 patients, and 38 patients returned to their former work. CONCLUSIONS: Injury Severity Score (ISS(90)) should be 17 in severe polytrauma patients, but in severe polytrauma patients who have mainly sustained orthopaedic trauma, the ISS(90) of bone and joint injuries should be 16. We recommend that primary minimally-invasive external fracture stabilization should be made for extremities and pelvis in these patients to avoid additional surgical trauma and that definitive secondary fracture care should be performed after medical stabilization for these patients in intensive care unit (ICU).
