RESUMO

In order to promote the high-value utilization of waste phosphogypsum (PG), hydroxyapatite was directly synthesized from PG by acid precipitation-hydrothermal method (PGHAP), which was used for the adsorption of bovine serum albumin (BSA) and lysozyme (LYS). The synthesized PGHAP was characterized by XRD, SEM, FTIR and BET, and the effects of various factors on protein adsorption capacity were studied. The results showed that PGHAP exhibits a clear needle-like morphology, high crystallinity, and an average size of about 200 nm. The pH had the greatest effect on the adsorption of protein, and the highest adsorption capacity was obtained at pH 4.0. In addition, the adsorption mechanism of protein on PGHAP was explored by adsorption kinetics and adsorption isotherm. The adsorption of protein on PGHAP conforms to the Intra-particle diffusion model kinetic model, the maximum adsorption capacity of protein on PGHAP can reach 31 mg/g, which is comparable to other adsorbents in this field. In addition, the adsorption behaviour of PGHAP on protein is more appropriately described by Langmuir isotherm model, which indicates that the binding site with uniform energy on the surface of PGHAP realizes the monolayer adsorption of protein. The main adsorption mechanisms are ion exchange, co-precipitation, complexation reaction and so on. Therefore, the needle-like PGHAP synthesized from waste PG is a protein adsorbent with industrial application potential.

RESUMO

BACKGROUND: Sotos syndrome is an autosomal dominant disorder, whereas attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition. This report aimed to summarize the clinical and genetic features of a pediatric case of Soros syndrome and ADHD in a child exhibiting precocious puberty. CASE SUMMARY: The patient presented with accelerated growth and advanced skeletal maturation; however, she lacked any distinct facial characteristics related to specific genetic disorders. Genetic analyses revealed a paternally inherited heterozygous synonymous mutation [c.4605C>T (p.Arg1535Arg)]. Functional analyses suggested that this mutation may disrupt splicing, and bioinformatics analyses predicted that this mutation was likely pathogenic. After an initial diagnosis of Sotos syndrome, the patient was diagnosed with ADHD during the follow-up period at the age of 8 years and 7 months. CONCLUSION: The potential for comorbid ADHD in Sotos syndrome patients should be considered to avoid the risk of a missed diagnosis.

RESUMO

The primary goal of this meta-analysis is to explore the five factors of knowledge, teamwork, learning satisfaction, anxiety, and interprofessional ability to determine the value of escape rooms in medical education. Up to January 2023, we searched ScienceDirect, Scopus, PubMed, Embase, Web of Science, CNKI, and the Cochrane Library for pertinent works in either English or Chinese. The Risk of Bias 2 (RoB 2) tool and Newcastle-Ottawa Scale (NOS) were used to assess the quality of studies. Subgroup and sensitivity analyses were used to assess statistical heterogeneity, and I2 was used to measure it. Overall, escape rooms had a more significant positive effect than traditional learning on knowledge (standardized mean difference [SMD]: 0.84; 95% confidence interval [CI]: 0.36-1.33), teamwork (SMD: 4.91; 95% CI: 4.58-5.24), learning satisfaction (MD: 0.36; 95% CI: 0.08-0.64), and interprofessional ability (SMD: 1.04, 95% CI: 0.81-1.27). Moreover, the impact of escape rooms on anxiety also had significant effects (SMD: -8.23, 95% CI: -11.64 to -4.82). Escape rooms affect medical students' knowledge, teamwork, learning satisfaction, interprofessional ability, and anxiety. The findings of this study can be used as evidence that escape rooms is a more effective method than traditional teaching for improving active learning.

RESUMO

AIM: This study adopted the qualitative research method, aiming to explore the learning experience of nursing graduate professional curricula in China from the perspective of students and provided a basis for the continuous improvement of nursing graduate training. DESIGN: A qualitative study. METHODS: A purposive sampling method was employed to conduct semi-structured in-depth interviews with 14 nursing master's students enrolled in professional curricula from September 03, 2021, to December 8, 2022. The Colaizzi seven-step analysis method was utilized for data analysis, summarization and extraction. RESULTS: Four themes emerged from the study findings: (i) The study of professional curricula is the cornerstone of scientific research work, but it is relatively boring; (ii) The teaching methods and assessment methods of postgraduate education need to be diversified; (iii) The postgraduate education needs to increase the study time of specialized courses and highlight the specialty characteristics; (iv) the study of professional curricula can enhance the comprehensive ability of postgraduate students. CONCLUSION: The study of professional curricula for post-graduate nursing students plays an important role in the development of post-graduate research and can statistically significant improve their comprehensive ability, but there are some problems such as boring courses, single teaching assessment methods and insufficient time. In the future teaching reform, it is necessary to highlight the specialty characteristics of nursing scientific research, optimize curriculum education and improve students' scientific research knowledge and thinking. PATIENT AND PUBLIC CONTRIBUTIONS: We thank all participants for their valuable input throughout the study.

RESUMO

BACKGROUND: Although past research has highlighted the importance of digital technology in clinical education among undergraduate nursing programs, facilitators and barriers to application still need to be systematically understood. AIM: The objective of this systematic review is to synthesize existing literature reporting on nursing students' experiences with digital technology in clinical education among undergraduate programs to identify gaps and design future educational programs. METHODS: We conducted a qualitative systematic review and reported the following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. PubMed, Embase, CINAHL, Web of Science databases were searched for studies published in English. Qualitative studies focusing on nursing students' experiences of digital technology in clinical education were included, and data were synthesized by extracting findings, developing categories, and developing synthesized findings. RESULTS: Six synthesized findings were concluded:1) nature of digital education, 2) facilitators, 3) barriers, 4) benefits to learning, 5) mixed experience, and 6) challenges. CONCLUSIONS: The systematic review revealed that the utilization of digital technology in clinical practice is beneficial to the learning of undergraduate nursing students. Facilitators and challenges of digital education, as well as barriers to digital education identified in this review can be used to design more effective digital education activities. Digital technology can be used to supplement traditional teaching, and it is worthwhile to explore more in the area of digital education to promote the cultivation of nursing students' competency.

RESUMO

The correlation between formaldehyde (FA) exposure and prevalence of asthma has been widely reported. However, the underlying mechanism is still not fully understood. FA exposure at 2.0 mg/m3 was found to exacerbate asthma in OVA-induced murine models. IFN-γ, the cytokine produced by T helper 1 (Th1) cells, was significantly induced by FA in serum and bronchoalveolar lavage fluid (BALF) of asthmatic mice, which was different from cytokines secreted by other Th cells. The observation was also confirmed by mRNA levels of Th marker genes in CD4+ T cells isolated from BALF. In addition, increased production of IFN-γ and expression of T-bet in Jurkat T cells primed with phorbol ester and phytohaemagglutinin were also observed with 100 µM FA treatment in vitro. Upregulated STAT1 phosphorylation, T-bet expression and IFN-γ production induced by FA was found to be restrained by STAT1 inhibitor fludarabine, indicating that FA promoted Th1 commitment through the autocrine IFN-γ/STAT1/T-bet pathway in asthma. This work not only revealed that FA could bias Th lineage commitment to exacerbate allergic asthma, but also identified the signaling mechanism of FA-induced Th1 differentiation, which may be utilized as the target for development of interfering strategies against FA-induced immune disorders.

RESUMO

Soil microbes are crucial in shaping the root-associated microbial communities. In this study, we analyzed the effect of the soil-root niche gradient on the diversity, composition, and assembly of the bacterial community and co-occurrence network of two cotton varieties. The results revealed that the bacterial communities in cotton soil-root compartment niches exhibited a skewed species abundance distribution, dominated by abundant taxa showing a strong spatial specificity. The assembly processes of the rhizosphere bacterial communities were mainly driven by stochastic processes, dominated by the enrichment pattern and supplemented by the depletion pattern to recruit bacteria from the bulk soil, resulting in a more stable bacterial community. The assembly processes of the endosphere bacterial communities were determined by processes dominated by the depletion pattern and supplemented by the enrichment pattern to recruit species from the rhizosphere, resulting in a decrease in the stability and complexity of the community co-occurrence network. The compartment niche shaped the diversity of the bacterial communities, and the cotton variety genotype was an important source of diversity in bacterial communities within the compartment niche. We suggest that the moderate taxa contribute to significantly more changes in the diversity of the bacterial community than the rare and abundant taxa during the succession of bacterial communities in the cotton root-soil continuum.

RESUMO

OBJECTIVE: As an integral part of emergency medical rescue teams during public health events, understanding the core competencies that nursing personnel should possess-including theoretical knowledge, practical skills, comprehensive abilities and personal traits-can provide a practical basis for better preparation and targeted training for future emergency rescue works. Thus, this study aims to provide a scientific and applicable reference for perfecting the routine training strategy of nursing personnel assembled by emergency medical rescue teams and improving the overall guarantee ability level of this group. DESIGN: This is a qualitative study conducted using individual semi-structured interviews. All interviews were recorded and transcribed verbatim for the purpose of thematic analysis and extraction. SETTING: Participants were recruited from February to March 2023, from four comprehensive hospitals in Chongqing China with the highest number of emergency relief works. PARTICIPANTS: A sample of experts (N=15) with extensive experience in emergency relief works was recruited in Chongqing, China. RESULTS: 60% of the experts held master's degrees or higher, 73.3% held senior or higher titles, 36.7% had participated in work execution more than five times and 73.3% held leadership positions in their current units and in the execution of emergency relief works. Four main themes and 22 corresponding subthemes were derived for the core competencies required for nursing personnel selected for emergency medical rescue teams in public health events, including theoretical knowledge, practical skills, comprehensive abilities and personal traits. CONCLUSIONS: Our study revealed that through interviews with 15 experts with extensive experience in the public health event, the essential elements of core competencies for nursing personnel assigned to emergency medical rescue teams during the public health event were identified. These can serve as a reference standard for the selection of nursing personnel in public health events, and provide a basis for the cultivation and evaluation of competency for nursing personnel assigned to emergency medical rescue teams in the public health event in China and globally.

RESUMO

Hexamethylene diamine, an important chemical intermediate for polyamides, can be synthesized through the two-step route of caprolactam (CPL) ammonolysis to 6-aminocapronitrile (ACN), followed by hydrogenation. This method has received increasing attention from academia and industry. However, studies on the catalyst structure-performance correlation in CPL ammonolysis are still sporadic. In this work, a series of anatase TiO2 with different oxygen vacancy concentrations was prepared by chemical reduction using NaBH4. The oxygen vacancy on TiO2 surface, presented as Ti3+ sites, substantially enhances the adsorption and activation of NH3, which are demonstrated as the key steps in ammonolysis. Owing to the synergistic effect of Ti3+ and Ti4+ species, the CPL conversion rate and ACN selectivity of 85 and 97%, respectively, are achieved within 250 h. Density functional theory calculations showed that the intermediates on oxygen vacancy-rich TiO2 had a more favorable adsorption energy compared to those on intact TiO2, which is in good agreement with the experimental results.

RESUMO

OBJECTIVES: Gonadotropin-releasing hormone (GnRHa) is the first choice for the treatment of patients with central precocious puberty (CPP). However, the effects of GnRHa on the endocrine system of CPP patients, including insulin sensitivity, lipid level, thyroid function, bone mineral density (BMD), and testosterone (T) level, are currently contradictory. Therefore, the long-term safety of GnRHa therapy remains controversial. CONTENT: A systematic literature search was performed using PubMed, Embase, Cochrane Library, and CNKI databases. The changes in HOMA-IR, TG, LDL-C, HDL-C, TSH, FT3, FT4, T, and BMD in CPP patients before and after GnRHa treatment were compared by meta-analysis. As the heterogeneity between studies, we estimated standard deviation mean differences (SMDs) and 95 % confidence intervals (CIs) using a random-effects model. Egger's test was used to assess publication bias. SUMMARY: A total of 22 studies were included in our meta-analysis. Compared with before GnRHa treatment, there were no statistically significant differences in endocrine indicators including HOMA-IR, TG, LDL-C, HDL-C, TSH, FT4, FT3, T, and BMD of CPP patients treated with GnRHa. OUTLOOK: Treatment with GnRHa for central precocious puberty will not increase the adverse effect on the endocrine system.

RESUMO

Aldehyde dehydrogenase 2 (ALDH2) deficiency caused by   genetic variant is present in more than 560 million people of East Asian descent, which can be identified by apparent facial flushing from acetaldehyde accumulation after consuming alcohol. Recent findings indicated that ALDH2 also played a critical role in detoxification of formaldehyde (FA). Our previous studies showed that FA could enhance macrophagic inflammatory responses through the induction of HIF-1α-dependent glycolysis. In the present study, pro-inflammatory responses and glycolysis promoted by 0.5 mg/m3 FA were found in mice with Aldh2 gene knockout, which was confirmed in the primary macrophages isolated from Aldh2 gene knockout mice treated with 50 µM FA. FA at 50 and 100 µM also induced stronger dose-dependent increases of pro-inflammatory responses and glycolysis in RAW264.7 murine macrophages with knock-down of ALDH2, and the enhanced effects induced by 50 µM FA was alleviated by inhibition of HIF-1α in RAW264.7 macrophages with ALDH2 knock-down. Collectively, these results clearly demonstrated that ALDH2 deficiency reinforced pro-inflammatory responses and glycolysis in macrophages potentiated by environmentally relevant concentration of FA, which may increase the susceptibility to inflammation and immunotoxicity induced by environmental FA exposure.

RESUMO

AIMS/INTRODUCTION: Thrombospondin-1 (TSP-1) participates in a series of physiological and pathological processes by binding to various receptors regulating cell proliferation, adhesion and apoptosis. Elevated circulating TSP-1 is linked with diabetic vascular complications (DVC). This study aimed to determine the relationship between circulating TSP-1 levels and DVC. MATERIALS AND METHODS: A comprehensive search of PubMed, Embase, Web of Science and CNKI databases was carried out. A meta-analysis was carried out to compare circulating TSP-1 levels between diabetes patients without vascular complications (DNVC), diabetes patients with DVC and non-diabetes patients. The correlation between TSP-1 and metabolic parameters was also analyzed. Subgroup analysis was carried out according to complication type, defined as diabetic retinopathy, diabetic nephropathy and diabetic cardiovascular disease (DCVD). RESULTS: A total of eight studies were included. Compared with non-diabetes patients, diabetic patients, including DNVC and DVC, had significantly higher circulating TSP-1 levels (standardized mean difference [SMD] 2.660, 95% CI 1.17-4.145, P = 0.000). DNVC had significantly higher circulating TSP-1 levels than non-diabetes patients (SMD 3.613, 95% CI 1.607-5.619, P = 0.000). DVC had significantly higher TSP-1 levels than DNVC (SMD 0.568, 95% CI 0.100-1.036, P = 0.017). TSP-1 was significantly positively correlated with fasting plasma glucose (overall Fisher's z = 0.696, 95% CI 0.559-0.833) and HbA1c (overall Fisher's z = 0.849, 95% CI 0.776-0.923). CONCLUSIONS: Elevated circulating TSP-1 levels are closely related to DVC, especially in diabetic nephropathy and diabetic cardiovascular disease. Circulating TSP-1 detection might be helpful in the timely diagnosis and treatment of DVC.

RESUMO

BACKGROUND: Progressive loss of peripheral muscle strength is highly pronounced in patients receiving maintenance hemodialysis (MHD), of which the pathological mechanism tends to be multifactorial. Plasma nickel was reportedly correlated with muscular strength in non-dialysis patients. However, scarce is known regarding the association between blood nickel level and handgrip strength among the patients undergoing MHD. METHODS: This cross-sectional study included patients undergoing MHD at our center in October 2021. Blood samples were collected before the hemodialysis sessions. Nickel level was measured using inductively coupled plasma mass spectrometry. Eligible patients were stratified into three groups by the blood nickel level: tertile 1 (≥ 5.2 ug/L); tertile 2 (< 5.2 ug/L and ≥ 4.5 ug/L); and tertile 3 (< 4.5 ug/L). Handgrip strength measurement was used to evaluate the muscle status. Spearman's analyses and multivariable linear regression analyses were performed to study the relationship between blood nickel level and handgrip strength. RESULTS: A total of 236 patients were enrolled, with an average age of 55.51 ± 14.27 years and a median dialysis vintage of 83 (IQR: 48-125) months. Patients in group with a higher blood nickel level (tertile 1) tended to be female, had longer dialysis vintage and higher Kt/V, but lower BMI, serum creatinine, hemoglobin, and handgrip strength level (all p < 0.05). After adjustment for confounding factors in multivariable models, for every 1ug/L increase in nickel level, the patient's handgrip strength decreases by 2.81 kg (ß: - 2.810, 95% confidence interval: - 5.036 to - 0.584, p = 0.014). Restricted cubic spline confirmed the relationship was nearly linear. CONCLUSIONS: Our study highlighted that blood nickel level was related to handgrip strength in patients undergoing MHD. Prospective studies with larger sample sizes are still needed to confirm the result.

RESUMO

The rational design of a solid electrolyte interphase (SEI) with high ionic conductivity and high electrochemical stability is significantly important in improving the electrochemical performance of anode materials. Herein, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to generate protective SEI films on Li3VO4 (LVO) anodes. The addition of LiDFOB is beneficial to form a dense, uniform, stable and LiF-richer SEI, which is helpful to boost the Li-ion storage kinetics. In addition, the generated SEI can inhibit the further decomposition of electrolytes and maintain the morphology of LVO anodes during charge/discharge processes. As a result, LVO-based anodes exhibit a much higher capacity (769.5 mA h g-1 at 0.5 A g-1), enhanced rate performance (243.3 mA h g-1 at 5.0 A g-1) and excellent long-term cycling stability (209.9 mA h g-1 after 5000 cycles) when cycled in 1 wt% LiDFOB addition electrolyte. This work confirms that LiDFOB is a promising multi-functional additive for LiPF6 electrolytes and provides new insights into SEI construction towards high-performance LVO anodes.

RESUMO

Purpose: The triglyceride glucose (TyG) index and TyG-related indicators have been proposed as a marker of insulin resistance. It is unclear which is the best indicator to predict diabetes mellitus (DM) in Chinese. This study aimed to investigate the predictive value of different biomarkers for the incidence of DM. Patients and methods: Between January 2017 and December 2020, 5575 subjects who underwent health examinations in Hebei General Hospital were retrospectively included. The primary endpoint was new onset DM. Results: During a median follow-up of 3.03 years, 133(2.39%) individuals developed DM. Multivariable cox proportional hazards models revealed that TyG index and TyG-related parameters were positively associated with DM risk. As the interaction analyses showed, there were significant interactions with sex and age levels in relation to DM risk (both P for interaction <0.05). Risk prediction for DM was significantly improved by adding TyG index to the baseline model using conventional diabetic risk factors in predicting DM at follow-up. Conclusion: This population-based cohort study suggested a causal relationship between TyG index and DM after adjusting for other confounding factors. This independent and significant association was more apparent in females and subjects younger than 65 years. Compared with the TyG-BMI, TyG-WC, TyG-WHtR, the TyG index was a more effective predictor of DM.

RESUMO

Formaldehyde (FA) exposure has been positively correlated with many diseases including various types of cancers. However, the mechanisms of FA-related carcinogenesis are still unclear. Tumor-associated macrophages (TAMs) are the most abundant immune cells in tumor microenvironment, which is a heterogeneous population consist of both pro-inflammatory (M1) and immunosuppressive (M2) cells. TAMs are deeply involved in tumor development and progression. Our previous studies demonstrated that FA enhanced M1 polarization of macrophages through induction of HIF-1α-mediated glycolysis. To examine if TAM polarizations are also potentiated by FA, BALB/c nude mice were inoculated with A549 cells to develop subcutaneous tumors and exposed to 2.0 mg/m3 FA for 14 days. Significant increases of both M1 and M2 polarizations of TAMs were observed in tumor tissues of FA-exposed mice. After confirmation of the potentiation effects in RAW264.7 and THP-1-derived in vitro TAM models, FA at 25 and 50 µM was found to enhance TAM immunosuppressive functions and glycolytic metabolism. In addition, FA-induced glycolysis in TAMs was reversed by a specific HIF-1α inhibitor PX-478 at 5 µM, and suppression of glycolytic metabolism with a glucose analog 2-DG at 1 mM also alleviated FA-potentiated TAM functions, which indicated that FA induced TAM polarizations through the upregulation of HIF-1α-mediated glycolysis. These results illustrated a potential carcinogenic mechanism of FA through metabolic disturbance of tumor immunity, which could be utilized to develop preventative or therapeutic agents for FA-induced carcinogenesis and immune disorders.

RESUMO

Recent studies linking adult height to diabetes risk remain controversial and few were from Asia. This study, therefore, aimed to explore the association of adult height with diabetes risk in a Chinese population. This retrospective cohort study was a secondary analysis of data from the DATADRYAD website, involving 211,172 non-diabetic individuals aged ≥ 20 years from the health screening program in China. Cox regression models were employed to evaluate hazard ratios (HRs) with 95% confidence interval (CI) of diabetes related to height. During an average 3.12-year follow-up, 4156 (1.97%) subjects reported developing diabetes. After adjusting for potential confounding factors, an inverse association of height with diabetes risk was observed among men and women [HR per 10 cm (95% CI), 0.78 (0.73-0.83) and 0.76 (0.68-0.86), respectively]. Moreover, subgroup analyses indicated the inverse association was only detected in individuals with aged < 70 years, fasting plasma glucose (FPG) < 6.1 mmol/L, and men with body mass index (BMI) < 28 kg/m2. In brief, height is inversely associated with diabetes risk in Chinese adults. Specifically, this association appears to be more pronounced in individuals with aged < 70 years, FPG < 6.1 mmol/L, and men with BMI < 28 kg/m2.

RESUMO

BACKGROUND: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) showed great value in treating nonalcoholic fatty liver disease (NAFLD). We aimed to compare the effectiveness of long-acting and short-acting GLP-1RAs on improving body weight and related metabolic parameters in patients with type 2 diabetes (T2DM) as a reference for the treatment of NAFLD with T2DM. METHODS: We searched eligible randomized controlled trials (RCTs) in PubMed, Embase, Cochrane and web of science database until August 2023. The risk of bias of included RCTs were assessed by the Risk Assessment of Cochrane Review items. We mainly drew forest plots to compare the effects of long and short acting GLP-1 RAs using RevMan 5.4. RESULTS: Twelve RCTs involving 2751 patients were included in our meta-analysis. Compared with short-acting GLP-1 RAs, the long-acting group was better in body weight (P < .00001, MD = -0.65, 95% confidence interval [CI] [-0.90, -0.40], I2 = 20%), and the same results in glycosylated hemoglobin (HbA1c) (P < .00001, MD = -0.43, 95% CI [-0.54, -0.33], I2 = 55%) and fasting plasma glucose (FPG) (P < .00001, MD = -0.77, 95% CI [-1.01, -0.52], I2 =70%). For the lipid parameters, long-acting drugs lowered cholesterol (TC) (P = .02, SMD = -0.19, 95% CI [-0.35, -0.03], I2 =57%) and low-density lipoprotein (LDL) (P = .02, SMD = -0.17, 95% CI [-0.33, -0.02], I2 =51%) more significantly compared with short-acting drugs. But treatment differences were not significant in triglycerides (TG) (P = .40, SMD = -0.05, 95% CI [-0.15, -0.06], I2 = 0%), and high-density lipoprotein (HDL) (P = .85, SMD = -0.01, 95% CI [-0.11, -0.09], I2 = 0%). CONCLUSION: Long-acting GLP-1RAs may be more promise than short-acting GLP-1RAs in improving weight and related metabolic parameters.

RESUMO

The development of lithium-ion batteries (LIBs) is still facing challenges due to the design and optimization of anode materials and their Li-ion storage mechanisms. In this study, we aimed to address this issue by constructing three-dimensional hierarchical heterojunction structures using a double needle electrospinning strategy. The heterostructure was composed of insertion-type Li3VO4 and conversion/alloying-type Ga2O3 embedded porous carbon nanofibers (Li3VO4-Ga2O3@PCNF). The designed heterostructured Ga2O3 and Li3VO4 materials were found to effectively enhance charge transfer dynamics, thereby improving capacity and rate capability. Additionally, the facilitated efficient contact between the electrode and electrolyte, enabling the diffusion of ions and electrons. When applied as an anode material in LIBs, the Li3VO4-Ga2O3@PCNF composite achieved a high capacity of 630.0 mA h g-1 at 0.5 A g-1, and full capacity recovery after 6 periods of rate testing over 480 cycles. When simulating the practical application under a high discharge current of 6.0 A g-1, the Li3VO4-Ga2O3@PCNF could still deliver a high discharge capacity of 322.0 mA h g-1 after 2000 cycles. Furthermore, the composite exhibited a remarkable capacity retention of 77.2% after 2000 cycles at 6.0 A g-1. This research provides valuable guidance for the design of high-performance Li3VO4-based anodes, particularly in addressing the issue of inferior electronic conductivity.

RESUMO

BACKGROUND: With frequent conflicts, natural disasters, and public health emergencies globally, mobile medical teams (MMTs) are becoming increasingly critical. Importantly, the competency of critical care nurses in MMTs can substantially affect the effectiveness and quality of its rescue efforts. Yet, these nurses' competencies are not well understood. AIM: This study examined the competencies of critical care nurses in MMTs using the Onion Model. DESIGN: A qualitative descriptive method was used to describe the competencies of Chinese MMT critical care nurses. METHODS: From April to May 2022, a convenience sample of 18 participants (14 critical care nurses and 4 surgeons) from 10 MMTs was recruited for semi-structured interviews. Deductive and inductive coding methods were combined for content analysis. RESULTS: In total, 29 competencies were identified, which were grouped into four major domains using the Onion Model. From the outer to inner layers, these domains were knowledge and skills, professional abilities, professional quality, and personal traits. Several novel competencies emerged, including field medical equipment operation skills, on-site hazard identification and safety prevention skills, triage knowledge, and field survival skills. CONCLUSIONS: Using the Onion Model, this study furthers the understanding of the competency of critical care nurses in MMTs, especially by revealing the novel competencies. Further, the results can be used to recruit, evaluate, and train critical care nurses for MMTs. RELEVANCE TO CLINICAL PRACTICE: Understanding MMT critical care nurses' competencies can help managers plan and provide relevant training and education before deployment, which can improve nurses' performance, and especially reduce the mortalities and disabilities from trauma.
