OBJECTIVE To comprehend the main pathogens and their drug resistance of multiple organ dysfunction syndrome(MODS) patients in ICU.METHODS We retrospectively analyzed all the bacteria isolated from 40 MODS patients in ICU.RESULTS The number of bacteria strains isolated was 173,92 G-bacteria strains made up 53.18%,60 G+ bacteria strains made up 34.68%,and 21 fungi strains made up 12.14%.The top six were Staphylococcus aureus(23.70%,MRSA was 13.87%),Pseudomonas aeruginosa(14.45%),Acinetobacter baumannii(11.56%),Stenotrophomonas maltophilia(8.67%),Candida tropicalis(8.09%),and Enterococcus faecalis(7.51%).The susceptive rate of S.aureus and Enterococcus to vancomycin was all 100%,the susceptive rate of A.baumannii and Klebsiella pneumoniae to carbapenems was high.64% patients had the multiplicity of infection(MOI) which always linked with long period in ICU,respiratory failure and mechanical ventilation.CONCLUSIONS MODS patients have a high morbility of G+ bacteria,fungi and MOI,most pathogens show multi-resistance to commonly used antibiotics.Strengthening the monitoring of infection and reasonable using antibiotics should be taken.

Objective To investigate professional maturity and career planning of nursing students and explore their correlation.Methods Totals of 138 nursing students were investigated by professional maturity scale and career planning scale.Results Both professional maturity and career planning of nursing students were average level,with the score of (3.08 ± 0.24),(3.47 ± 0.41),and professional maturity degree was positively correlated with career planning level (P ＜ 0.05).Conclusions Professional maturity and career planning of nursing students have a certain degree of development,but there is still some gap to mature period,and the imbalance appears in various dimensions.Clinical nursing educators should strengthen the self-confidence of nursing students,and guide career planning according to the degree of professional

Malnutrition is relatively common in patients with cardiovascular diseases and is closely related to the poor prognosis of the disease. This article reviewed the main contents and application status, advantages and disadvantages of various nutritional assessment tools for the patients with cardiovascular diseases to provide the basis for healthcare professionals to select the appropriate nutritional assessment method of patients with cardiovascular diseases, identify their malnutrition as early as possible, and implement targeted nutritional interventions.

Objective:To learn the application of nosocomial infection prevention and control measures as stipulated in COVID-19 emergency plans by medical institutions at all levels in the region, for the purpose of strengthening epidemic prevention and control.Methods:During March 12-13, 2020, customized questionnaires were used to learn from 186 hospitals and medical institutions regarding the basics of their nosocomial prevention management departments, emergency plan application and revisions made. Comparison of the ratios or constituent ratios were tested with χ2 test, while the continuous variables analysis between groups was verified with one-way ANOVA. Results:77.53% of the medical institutions had set up independent nosocomial infection management departments, and 87.30% of the institutions were qualified. 80% of the medical institutions had in place emergency plans for respiratory infectious diseases, but 98.05% of them had revised their plans during the pandemic, with an average of 10.85 newly added and revised provisions. Only 30.11% of emergency planed provide for clearly graded early warning.Conclusions:Efforts should be upgraded to develop an emergency prevention and control system for infection prevention and control in epidemics, and improve technical support for infection prevention and control in the system; to strengthen the clearly-graded early warning and graded responses in a scientific manner; and conduct regular drills, revise plan to ensure its applicability.

ObjectiveTo systematically evaluate the safety of interferon β-1a for treatment of corona virus disease 2019 （COVID-19）， and to provide references for interferon β-1a's clinical application. MethodsThis study was conducted with the database from US Food and Drug Administration adverse event reporting system （FAERS） from January 1， 2015 to March 31， 2021. Information component （IC） and reporting odds ratio （ROR） methods were applied for signal mining. ResultsA total of 463 700 records of COVID-19 were selected for analysis， and 45 positive drug adverse event signals were detected. Headache （IC₀₂₅=1.09， ROR₀₂₅=2.28）， pyrexia （IC₀₂₅=0.51， ROR₀₂₅=1.51） and multiple sclerosis relapse （IC₀₂₅=3.67， ROR₀₂₅=14.71） were positive adverse events with higher frequency. Autoimmune disorder （IC₀₂₅=4.42， ROR₀₂₅=24.03）， streptococcal infection （IC₀₂₅=4.12， ROR₀₂₅=19.82）， and multiple sclerosis relapse （IC₀₂₅=3.67， ROR₀₂₅=14.71） were positive adverse events. Acute lung injury， cardio-respiratory arrest and metabolic acidosis were associated with a higher proportion and frequency of death. ConclusionThere are certain safety issues with interferon β-1a in the treatment of COVID-19， and some adverse events with high frequency and high death rate deserve further attention by medical staffs.
