Methods: This study used a quasi-experimental design with a one-group pretest-posttest research design to identify the knowledge and skills of emergency department (ED) nurses in managing CVD. There were 16 participants in this study. The mean, standard deviation (SD), and t-test were used to analyze the data. Results: Before the participants undergo the program, they have a mean (SD) score of 17.63 (5.19). After the completion of the didactic part of the program, they garnered a mean (SD) score of 19.94 (5.22). Moreover, after completion of the practicum part of the program, the mean (SD) score was 21.94 (5.04). Comparing the scores before the program and after finishing the didactic part of the program, the t-test scored (t (15) = -3.87, P = 0.001). Further, comparing the scores before the program and after finishing the didactic and practicum parts of the program, the t-test scored (t (15) = -5.57, P = 0.001). Conclusions: Based on the study’s results, the researchers conclude that the respondents had acceptable knowledge regarding the emergency management of CVD before the program. However, the Cardiac Enhancement Program for Emergency Cardiac Care boosted their knowledge. Also, the program is effective in enhancing the participants’ knowledge of the emergency management of CVD.展开更多

文摘Shotcrete is one of the common solutions for shallow sliding.It works by forming a protective layer with high strength and cementing the loose soil particles on the slope surface to prevent shallow sliding.However,the solidification time of conventional cement paste is long when shotcrete is used to treat cohesionless soil landslide.The idea of reinforcing slope with polyurethane solidified soil(i.e.,mixture of polyurethane and sand)was proposed.Model tests and finite element analysis were carried out to study the effectiveness of the proposed new method on the emergency treatment of cohesionless soil landslide.Surcharge loading on the crest of the slope was applied step by step until landslide was triggered so as to test and compare the stability and bearing capacity of slope models with different conditions.The simulated slope displacements were relatively close to the measured results,and the simulated slope deformation characteristics were in good agreement with the observed phenomena,which verifies the accuracy of the numerical method.Under the condition of surcharge loading on the crest of the slope,the unreinforced slope slid when the surcharge loading exceeded 30 k Pa,which presented a failure mode of local instability and collapse at the shallow layer of slope top.The reinforced slope remained stable even when the surcharge loading reached 48 k Pa.The displacement of the reinforced slope was reduced by more than 95%.Overall,this study verifies the effectiveness of polyurethane in the emergency treatment of cohesionless soil landslide and should have broad application prospects in the field of geological disasters concerning the safety of people's live.
文摘Emergency department nurses face severe occupational stress leading to anxiety,depression,and burnout,which significantly impair their well-being and patientcare quality.This narrative review examined the role of mindfulness-based stress reduction(MBSR)in addressing these challenges.Rooted in nonjudgmental present-moment awareness,MBSR enhances emotional regulation and reduces psychological distress by fostering adaptive coping strategies.Studies have demonstrated its efficacy in lowering anxiety,depressive symptoms,and emotional exhaustion,while improving workplace well-being,empathy,and job satisfaction.Mechanistically,MBSR improves interoceptive awareness and autonomic balance,as evidenced by physiological markers such as heart rate variability.However,gaps remain in long-term efficacy assessments,personalized interventions,and integration with multidisciplinary approaches.Future research should prioritize tailored biomarker-driven programs,longitudinal studies,and scalable implementation strategies in high-stress clinical settings.This review underscores MBSR’s potential as a sustainable,evidence-based tool to enhance emergency department nurses’mental health and professional performance,advocating for broader adoption and further refinement of its practical applications.

文摘Typhoons can cause large-area blackouts or partial outages of distribution networks.We define a partial outage state in the distribution network as a gray state and propose a gray-start strategy and two-stage distribution network emergency recovery framework.A phase-space reconstruction and stacked integrated model for predicting wind and photovoltaic generation during typhoon disasters is proposed in the first stage.This provides guidance for second-stage post-disaster emergency recovery scheduling.The emergency recovery scheduling model is established in the second stage,and this model is supported by a thermal power-generating unit,mobile emergency generators,and distributed generators.Distributed generation includes wind power generation,photovoltaics,fuel cells,etc.Simultaneously,we con-sider the gray-start based on the pumped storage unit to be an important first step in the emergency recovery strategy.This model is val-idated on the improved IEEE 33 node system,which utilizes data from the 2022 super typhoon“Muifa”in Zhoushan,Zhejiang,China.Simulations indicate the superiority of a gray start with a pumped storage unit and the proposed emergency recovery strategy.

文摘BACKGROUND:Sepsis-associated encephalopathy(SAE)is a diff use dysfunction of the nervous system resulting from sepsis originating outside the central nervous system.Elderly individuals(≥65 years of age)constitute a particularly vulnerable population comprised by a high burden of underlying diseases and complications,which frequently leads to underdiagnosis or misdiagnosis.These patients are at increased risk of long-term or permanent central nervous system impairment,making rapid and accurate diagnosis and treatment especially critical.The review is expected to promote improvements in the diagnosis and treatment of SAE in elderly patients,ultimately achieving more standardized and effi cient SAE management.METHODS:We performed a literature search in four databases-PubMed,Embase,China National Knowledge Infrastructure(CNKI),and Wanfang-from inception to April 2025 using bilinguals(Chinese and English).RESULTS:The diagnostic criteria for SAE in elderly individuals include the following:(1)sepsis;(2)new-onset neurological dysfunction;and(3)exclusion of other causes of neurological dysfunction.Physicians should develop tailored empiric anti-infective plans for elderly SAE patients,considering comorbidities,organ function,infection site,local bacterial spectrum,and resistance.The treatment protocol can be adjusted once the pathogen is identifi ed.Stabilizing hemodynamics and ensuring cerebral perfusion are two fl uid resuscitation strategies used in elderly SAE patients.An individualized approach to fl uid resuscitation using restrictive fl uid volumes should be employed.Supportive treatment for elderly SAE patients focuses on improving tissue perfusion/oxygenation,controlling blood glucose levels,and correcting internal imbalances.Early rehabilitation,nutritional support,cognitive training,and family-based emotional support are important components of comprehensive care.CONCLUSION:The diagnosis and management of SAE in elderly patients support early recognition and timely intervention.
文摘Objective:To evaluate laboratory findings that predict bacterial meningitis in emergency service and their diagnostic effectiveness.Methods:This retrospective cohort study analyzed data from patients presenting with meningitis symptoms at a referral hospital in Mersin,Turkey,between January 2019 and January 2022.Clinical findings and laboratory results,including leukocyte count,C-reactive protein(CRP),and procalcitonin levels in blood,were examined.Logistic regression,Chi square test,and receiver operating characteristics(ROC)curve analyses assessed the predictive value of these parameters.Results:A total of 199 participants were included in the study;99 patients were diagnosed with meningitis after lumbar puncture and 100 served as controls.Patients with meningitis exhibited significantly higher leukocyte counts(median:11890×10^(3)/μL vs.7905×10^(3)/μL,P<0.001)and CRP levels(median:6.00 mg/dL vs.0.95 mg/dL,P<0.001)compared to controls.Procalcitonin levels were significantly elevated in meningitis patients(median:0.21 ng/mL vs.0.10 ng/mL,P<0.001).Logistic regression identified albumin(OR=0.16,95%CI=0.06-0.40),and CRP(OR=1.18,95%CI=1.08-1.28)as independent predictors of meningitis.ROC analysis for CRP demonstrated a sensitivity of 80.6%and specificity of 70.0%at a cut-off value of 2.23 mg/dL(AUC=0.792).Conclusions:Elevated albumin levels and CRP contents in the blood were significant predictors of meningitis in emergency service.Early identification of predictive markers may aid in timely lumbar puncture and management of atypical cases.
文摘As the healthcare system advances and expands in its services,the challenges of remaining efficient become more important.Emergency medical services(EMS)are vital cornerstones of communities.In many countries,EMS is available for every individual,regardless of their social or insurance status,via a toll-free telephone number.Understanding the risk factors for busy days in EMSs might be helpful for improving the allocation of resources,which is the key to better care for all patients in the prehospital setting.[1]An important factor influencing ambulance call volume could be the interplay of public behavior and weather.

文摘Objective: To assess the effectiveness of the created program in enhancing the knowledge of emergency room (ER) nurses in the emergency management of cardiovascular diseases (CVD). Methods: This study used a quasi-experimental design with a one-group pretest-posttest research design to identify the knowledge and skills of emergency department (ED) nurses in managing CVD. There were 16 participants in this study. The mean, standard deviation (SD), and t-test were used to analyze the data. Results: Before the participants undergo the program, they have a mean (SD) score of 17.63 (5.19). After the completion of the didactic part of the program, they garnered a mean (SD) score of 19.94 (5.22). Moreover, after completion of the practicum part of the program, the mean (SD) score was 21.94 (5.04). Comparing the scores before the program and after finishing the didactic part of the program, the t-test scored (t (15) = -3.87, P = 0.001). Further, comparing the scores before the program and after finishing the didactic and practicum parts of the program, the t-test scored (t (15) = -5.57, P = 0.001). Conclusions: Based on the study’s results, the researchers conclude that the respondents had acceptable knowledge regarding the emergency management of CVD before the program. However, the Cardiac Enhancement Program for Emergency Cardiac Care boosted their knowledge. Also, the program is effective in enhancing the participants’ knowledge of the emergency management of CVD.
