Objective:To explore the current situation of work stress and job burnout of nursing staff in the Department of Infectious Diseases, and analyze its influencing factors.Methods:From January to June 2020, 63 nurses from the Department of Infectious Diseases of Zhejiang Hospital and the Affiliated Hospital of Chengde Medical University were selected as research subjects. Questionnaires were used to investigate general information, work stress, and job burnout.Results:63 questionnaires were issued and 60 were recovered. There was a statistically significant difference in work stress scores of nurses with different working hours, daily number of patients admitted, public recognition and respect, and training times ( P<0.05) . There were statistically significant differences in the scores of the personal accomplishment dimension of nurses with or without administrative positions and different professional titles, and in the scores of the depersonalization tendency dimension of nurses with different education levels, public recognition and respect, and training times, and in the scores of the emotional exhaustion dimension of nurses with different working hours, daily number of patients admitted, public recognition and respect, and training times ( P<0.05) . Conclusions:Nursing staff in the Department of Infectious Diseases are under high work stress, overall burnout is mild, and the personal sense of accomplishment of the nursing staff is low. The main reasons for this are closely related to the daily number of patients admitted, public recognition and respect, and the training times.

Objective:To explore the clinical efficacy and safety of the new targeted anti-immunoglobulin E (IgE) drug Omalizumab in the treatment of children with moderate and severe allergic bronchial asthma in China.Methods:The clinical data of children with moderate and severe allergic asthma who were treated in the Department of Pediatrics of Peking University First Hospital from July 2018 to January 2020 and treated with Omalizumab were retrospectively analyzed.A comparison was performed on the changes of questionnaires, including childhood asthma control test (C-ACT), pediatric asthma quality of life questionnaire (PAQLQ), mini-asthma quality of life questionnaire (Mini-AQLQ) and global evaluation of asthma treatment effectiveness (GETE), pulmonary function test, including forced expiratory volume in the first second (FEV 1), percentage to predicted value (FEV 1% pred) and small airway function, fractional concentration of exhaled nitric oxide (FeNO) and so on, before and after treating with Omalizumab. Results:A total of 15 pediatric patients completed 16 weeks of treatment follow-up.After 16 weeks of Omazumab treatment, the score of C-ACT increased from (16.001.66) scores to (25.38±0.64) scores ( F=11.969, P<0.001), PAQLQ increased from (118.08 ± 23.78) scores to (141.00 ± 11.91) scores ( F=9.289, P=0.001), Mini-AQLQ increased from (78.93±7.43) scores to (97.92±3.12) scores ( F=4.145, P=0.042), and GETE decreased from (2.47±0.27) scores to (1.60±0.19) scores ( t=2.982, P=0.010). The actual value of FEV 1, FEV 1% pred, the maximum expiratory flow percentage of the predicted value (PEF% pred), forced expiratory flow at 25% (MEF 75), forced expiratory flow at 50% (MEF 50) and maximum midexpiratory flow (MMEF 75/25), increased from (1.96±0.12) L to (2.17±0.21) L ( F=0.425, P=0.789), (81.46±2.85)% to (82.64±1.55)% ( F=0.926, P=0.465), (82.05±3.58)% to (91.10±4.67)% ( F=1.909, P=0.128), (60.36±7.43)% to (76.94±4.65)% ( F=2.120, P=0.096), (52.72±3.75)% to (73.80±8.34)% ( F=3.140, P=0.047) and (60.05±8.47)% to (74.86±10.85)% ( F=7.860, P=0.010), respectively.FeNO decreased from 25.0 (14.5, 35.5) μg/L to 20.0 (18.5, 30.0) μg/L ( Z=-0.206, P=0.840). Transient headache was observed in 1 case and evanescent eruption in 2 cases during the treatment, respectively. Conclusions:Omalizumab can significantly improve the clinical manifestations, lung function indicators and quality of life of children with moderate and severe allergic asthma, and has good safety.Thus, it is expected to play an important role in the treatment of children with moderate-to-severe allergic asthma.

Objective To investigate the correlation between the frailty and nutritional status of the elderly hospitalized patients.Methods A total of 244 hospitalized patients were enrolled in this investigation. By using comprehensive geriatric assessment (CGA),patients answered these questions together with experts (questionnaire assessment by professional instructions). Researchers input the result into computer at same time. Results Compared with normal patients,frailty patients were older (P<0.001),and had lower ability to take care of themselves (P<0.001),in other words,they had more demands from their families and carers in terms of medical care (P<0.01). In addition, frailty patients had higher risks of having depressive symptom (P=0.016),cognitive impairment (P<0.001), living function disability (P<0.001),as well as malnutrition (P<0.001). Regression analysis result showed a negative correlation between frailty and nutrition (P=0.005).Conclusions Malnutrition is closely related to frailty,and malnutrition patients and patients with risks of malnutrition were easily to acquire frailty.

ObjectiveTo explore the effects of comprehensive geriatric assessment(CGA)on nursing safety management in general geriatric wards.Methods The safety problems existing before CGA,including falls, pressure sores,falling down from bed,catheter slippage and aspiration,were analyzed retrospectively. CGA was performed for each patient. Individualized intervention and integrated safety management was given to the patients on the basis of assessment results,after which,safety data were collected and analyzed again.Results Based on the CGA for the incidence of adverse nursing safety events within 2 years before and after the intervention,the incidence of falls dropped from 2.46% to 0.56%,the incidence of pressure sores from 1.23% to 0,the incidence of falling down from bed from 0.92% to 0,the incidence of catheter slippage from 3.08% to 0.56%,and the incidence of aspiration from 1.54% to 0.56%. The incidence of adverse events after the CGA,including falls,falling down from bed and catheter slippage,was lower than that before the CGA(P<0.05).Conclusions Early general assessment and intervention as well as ward safety management and assessment on the basis of CGA can reduce or eliminate adverse events in hospital,and enhance the effects of ward safety management.

Objective To study the correlation between time of fever onset in the course of patients'illness and etiologies of fever of unknown origin (FUO).Methods A total of 1 570 patients with FUO admitted from January 2013 to December 2014 were retrospectively analyzed, and clinical data ( sex, age, time of fever onset) of 348 patients meeting FUO diagnosis criteria with definite etiology diagnosis and time of fever onset were collected for multivariate logistic regression analysis after bias check.Results No statistically significant bias was found between 348 selected cases and 1 570 overall cases in gender (χ2 =0.029, P=0.903) and age (t=-1.040, P=0.299), and multivariate logistic regression analysis showed positive correlation between fever onset during 13: 00-18: 00 and infection (P=0.044, B=1.275), 18:00-24: 00 and connective tissue diseases ( P =0.029, B =0.838 ) , and showed negative correlation between age and miscellaneous (P =0.010, B =-0.042).Conclusions Characteristics of fever onset time may have significant value in preliminary diagnosis and guiding the correct direction of final definite diagnosis by means of targeted examinations or diagnostic treatments.It is worth to be further studied and discussed.

Objective To construct the risk model for healthcare-associated infection (HAI)with multidrug-re-sistant organisms(MDROs)in intensive care unit (ICU).Methods 836 patients who were admitted to ICU for more than 48 hours between October 2012 and September 2015 were analyzed retrospectively,logistic regression model of HAI was constructed,the model was conducted goodness of fit tests and the area under ROC curve analysis. Results Among 836 patients,incidence of HAI with MDROs was 14.23%(n=119).15 variables that were statis-tically significant in univariate analysis were included in logistic multivariate analysis,the results showed that the following variables entered into logistic regression equation:length of ICU stay (OR,2.493 [95%CI ,1 .816 -3.494]),underlying diseases (OR,1 .536 [95%CI ,1 .243 - 1 .898 ]),hypoproteinemia (OR,87.211 [95%CI , 36.165-210.304]),ventilator days (OR,1 .723 [95%CI ,1 .399-2.121 ]),fever(OR,20.639 [95%CI ,3.462 -123.043]),and primary pulmonary infection (OR,0.295 [95%CI ,0.133 -0.664]).Evaluation of model effect:sensitivity 95%,specificity 87.9%,the area under ROC curve 0.973.Conclusion Logistic regression model has a high goodness of fit in predicting HAI among ICU patients.

Objective: To evaluate the clinical value of echocardiography in aortic valvuloplasty (AVP) in the low-age pediatric patients with congenital aortic valve stenosis. Methods: We retrospectively studied 39 low-age (at median of 23 months) patients with congenital aortic valve stenosis who received aortic valve repair in our hospital for their echocardiography information, and statistically analyzed the main indicator changes by 4 time points as pre-operation and 1 week, 1-3 months, 6-12 months after the operation respectively. Results: In our study, the bicuspid to tricuspid valve ratio was approximately at 5.5/1 and 2 patients died during peri-operative period. Compared with pre-operative time point, Doppler aortic valve peak velocity (Vmax ) and the mean aortic transvalvular pressure gradient (MPG) were reduced accordingly, for Vmax: (4.30 ± 0.73) m/s vs (2.65 ± 0.78) m/s, (2.93 ± 0.63) m/s, (3.01 ± 0.83) m/s,P<0.01, for MPG: (45.78 ± 15.19) mmHg vs (18.24 ± 10.08) mmHg, (21.01 ± 10.08) mmHg, (22.31 ± 13.41) mmHg. Compared with pre-operative time point, left ventricular ejection fractions (LVEF) were similar in 3 post-operative time points. Compared with 1 week post operative time point, left ventricular end-diastolic anteroposterior diameter (LVEDD) was increased at 6-12 months post-operative time point, the relative wall thickness (RWT) was decreased, bothP<0.05, and aorta valve regurgitation (AR) was increasedP<0.01. Pearson correlation analysis showed that aortic annulus (AA) inner diameter was positively related to LVEDD (r= 0.648,P<0.01), negatively related to Vmax (r= -0.205,P<0.05) and RWT was positively related to Vmax (r= 0.196,P<0.05). There were 6 patients with pre-operatively decreased LVEF, 1 of them died and the rest 5 with elevated LVEF at 6-12 months post-operative period,P<0.05. Conclusion: Echocardiograghy could be used as the ifrst choice of imaging method for diagnosing congenital aortic valve stenosis, it has the important role for in-operative monitoring and post-operative evaluation of AVP in relevant patients.

Extra-nodal malignant lymphoma is often characterized by a lack of typical symptoms and positive results of auxiliary examinations, which make diagnosis difficult. In some cases, fever can be the only clinical manifestation. For the lymphoma patients presenting with persistent fever with a duration over 3 weeks, characteristics of fever including time of fever attack, fever type and effects of drugs may have significant value in the diagnosis, especially in the early stage of the disease or in rare cases.
