Objective:To explore the perioperative safety management of patients with severe limb dysplasia, to select appropriate methods to monitor vital signs, and to prevent intraoperative acquired pressure sore, nosocomial infection and other related complications.Methods:A case of severe developmental disorder of extremities caused by acroscleroderma in November 2019 in Peking University Shenzhen Hospital needed to be amputated. By organizing multidisciplinary consultation to discuss the operation plan, repeatedly selecting appropriate tools, and multiple scenario simulation exercises, continuous transcutaneous oxygen saturation and noninvasive blood pressure monitoring could be realized for the patients with acromegaly deficiency of the extremities. Under the monitoring of color ultrasound, the arterial blocking pressure of the extremities was determined as the tourniquet pressure during the operation value, take appropriate measures to prevent intraoperative acquired pressure sore, nosocomial infection and other related complications.Results:With the cooperation of multidisciplinary team, amputation was successfully carried out for the patients. The position was comfortable during the operation, the operation process was smooth, the residual limbs healed well after the operation, and there was no intraoperative acquired pressure sore, nosocomial infection and other related complications.Conclusions:To establish a multidisciplinary cooperation mechanism, strengthen the construction of the operating room special group, and use evidence-based nursing methods and actual scenario simulation exercise can ensure the perioperative safety of patients with severe developmental disorder of extremities and similar patients with special body shape or very low weight.

Objective To investigate the characteristics of intestinal microbiota in neonates on the first and third day after birth.Methods A total of 50 healthy singleton neonates who were born between June 15,2016 and August 3,2016 in Shanghai First Maternity and Infant Hospital were enrolled.Their stool samples were collected on the first and third day after birth and the samples were labeled according to the time of collection (D1 and D3 groups,n=50 each).Illumina NexSeq high-throughput sequencing platform was used to sequence the variable region 4 and 5 of all bacterial 16S rRNA genes in the samples.The composition of intestinal microbial communities was determined and the differences between the two groups were compared by Metastats analysis.Results (1) A total of 100 stool samples were sequenced and the retrieved sequences were from 25 bacterial phyla,119 families,227 genera and 159 species.(2) Major phyla in the two groups were the same,namely,Proteobacteria,Frimicutes,Bacteroidetes and Actinobacteria.The relative abundances of Frimicutes (0.27 ± 0.03 vs 0.41 ± 0.05) and Bacteroidetes (0.07 ± 0.01 vs 0.09 ± 0.03) increased over time,while that of Actinobacteria (0.10±0.01 vs 0.01 ±0.00) decreased on day 3.No significant difference in the relative abundance of Proteobacteria (0.51 ±0.03 vs 0.49± 0.05) was observed between D1 and D3 groups.There were significant difference in relative abundances of Frimicutes and Actinobacteria between the two groups (both q=-0.01,both P＜0.05).(3) Among the top ten most abundant families,Enterobacteriaceae,Staphylococcaceae,Enterococcaceae,Streptococcaceae and Lachnospiraceae were detected in both of the two groups.The relative abundances of Enterobacteriaceae (0.25 ± 0.02 vs 0.46 ± 0.06),Staphylococcaceae (0.07 ± 0.02 vs 0.12 ± 0.03),Enterococcaceae (0.04±0.02 vs 0.10±0.04),Streptococcaceae (0.03 ±0.02 vs 0.06±0.01) increased over time,while that of Lachnospiraceae (0.03 ± 0.01 vs 0.02 ± 0.02) decreased on day 3.Only the relative abundance of Enterobacteriaceae had statistical difference between the two groups (q=0.00,P＜0.05).(4) Among the top ten most abundant genera,Staphylococcus,Enterococcus,Streptococcus,Bacteroides and Pseudomonas were detected in both groups.The relative abundances of aerobic and facultative anaerobic bacteria which belonged to genera of Stenotrophomonas,Propionibacterium,Acinetobacter,Bacillus,Sphingomonas and so on decreased on day 3 as compared with those on day 1 (0.00±0.00 vs 0.07±0.02,0.00±0.00 vs 0.06±0.01,0.00±0.00 vs 0.03±0.01,0.00±0.00 vs 0.02±0.01,0.00±0.00 vs 0.02±0.00,all q=0.00,all P＜0.05).However,the relative abundances of anaerobic bacteria which belonged to Bacteroides,Veillonella,Parabacteroides and so on increased on day 3 (0.01 ±0.00 vs 0.08±0.03,0.00±0.00 vs 0.03±0.02,0.00±0.00 vs 0.01 ±0.00,q=0.01,0.01 and 0.00,all P＜0.05).(5) The most abundant species in intestinal microbiota was escherichia coli in both groups.Three less abundant species including lactobacillus gasseri,lactobacillus animalis and bifidobacterium bifidum were detected in both groups.(6) Regardless of the mode of delivery,Staphylococcus,was the highest predominant genera in meconium samples,followed by stenotrophomonas.Stool samples collected on the third day after birth were divided into four groups based on deliver modes and feeding patterns.Neonates who were born abdominally with exclusive breastfed thereafter were different from those of the other three groups in predominant intestinal bacteria,but the difference was not statistically significant.Bifidobacterium and Subdoligranulum were only detected in the vaginally born neonates.Conclusions Meconium is not sterile.Although the intestinal microbiota on the first day of life is different from that on the third day of life,the dominant bacteria are common.During the first three days of life,the relative abundances of aerobic and facultative anaerobic bacteria decreased significantly over time,while the relative abundance of anaerobic bacteria increased.

Objective:To develop a negative emotion screening scale for inpatients(NESSI) and test its validity and reliability.Methods:Based on our previous studies and the theory model of psychological stress, the original item pool was established through literature review, expert interviews and patient consultation.The first version of NESSI was constructed by Delphi method, then initially tested in 421 inpatients followed by the project analysis and reliability test. After those above, the formal scale was developed and tested in 318 inpatients followed by confirmatory factor analysis and reliability test.Finally, 7-item generalized anxiety disorder scale (GAD-7), 9-item patient health questionnaire (PHQ-9), anger state expression scale (SAS) and simplified Chinese version of fear of disease progression scale(FoP-Q-SF) were used to test the criterion validity.Results:After exploratory factor analysis, 17 items were retained in the final scale, which can be categorized into four dimensions: fear of illness, depression, somatization and anger, which could explain 63.49% of the total variation.Confirmatory factor analysis showed that the fitting degree of each factor model was good and met the requirements of reference value (χ 2/ df=2.949, RMR=0.044, CFI=0.929, NFI=0.897, IFI=0.930, TLI=0.915, PGFI=0.655, RMSEA=0.078). The Cronbach's α coefficient of the total scale was 0.925, and the Cronbach's α coefficient of the four factors ranged from 0.762 to 0.898.The criterion validity showed that there was a significant positive correlation between the scale and the four criterion scales ( r= 0.574-0.805, all P<0.01). Conclusion:The NESSI scale has good reliability and validity, and can be used as a psychological problem screening tool among non-psychiatric inpatients.

Objective:To investigate the assessment and occurrence of first-occured venous thromboembolism(VTE) among hospitalized patients.Methods:The clinical data of 6 532 surgical patients in Shenzhen Hospital, Peking University who were admitted from May 1, 2021 to June 30, 2021 were collected and analyzed retrospectively. The demographic data, Caprini score at admission and the incidence of VTE during hospitalization were analyzed by two independent sample t test and chi square test. Results:The Caprini score at admission of 6 532 patients was 1.81 ± 1.71. The number of cases in high, medium and low risks was 363 (5.6%), 1 189 (18.2%), 4 980 (76.2%), respectively. There was significant difference in VTE risk assessment scores and grades in different gender ( t=5.31, χ 2=48.31), length of stay ( F=195.21, χ 2=548.52) and hypertension ( t=17.07, χ 2=280.89), diabetes ( t=12.14, χ 2=51.18), smoking ( F=31.71, χ 2=53.23) and drinking ( F=18.78, χ 2=30.07) ( P<0.05). Forty-four(0.7%) patients got hospital-acquired VTE totally, among which, 24 cases (6.6%) were in high-risk, 14 cases (1.2%) were in medium-risk and 6 cases (0.1%) were in low-risk. What′s more, the top five VTE risky departments based on the assessment were not completely consistent with the top five departments with the highest incidence of VTE. Conclusions:The hospitalized patients are at high risk of VTE. The risk factors of diabetes, hypertension, smoking, drinking and other related factors should be included in the evaluation model. Meanwhile, the VTE risk assessment of in-patients should be emphasized and prophylactic treatments should be taken to reduce the incidence of VTE.

Objective:A comparison was made between the predictive efficacy of the Padua Score and the simplified Assessment Scheme Recommended by Chinese experts (hereinafter referred to as the Simplified Method) for the risk assessment of venous thromboembolism (VTE) in medical inpatients, aiming to provide a reference for the clinical selection of appropriate risk assessment tools.Methods:A retrospective cohort study was conducted, selecting 42 257 internal medicine inpatients discharged from Peking University Shenzhen Hospital between May 1, 2021, and April 30, 2022, using a convenience sampling method. Data collected included general information upon admission, VTE-related information, occurrences of VTE during hospitalization, and results from the two assessment tools. The predictive efficacy of the tools was evaluated by plotting ROC curves and calculating AUC, sensitivity, specificity, positive predictive value, negative predictive value, and predictive accuracy.Results:Among 42 257 patients, there were 21 065 male and 21 192 female participants, aged (55.04 ± 15.17) years old. The incidence rate of VTE among medical inpatients was 2.24% (948/42 257). The AUC for Padua Score and the Simplified Method in medical patients were 0.735 (95% CI 0.717-0.753) and 0.582 (95% CI 0.561-0.602), respectively. Sensitivities were 49.4% and 18.2%, specificities were 89.6% and 98.1%, positive predictive values were 9.9% and 17.7%, negative predictive values were 98.7% and 98.1%, and predictive accuracy were 88.7% and 96.3%, respectively. The departments with the highest incidence rates of VTE during hospitalization were rehabilitation medicine, emergency, neurology, geriatrics, and respiratory medicine. Within these departments, the AUC values for the Padua Score and the Simplified Method were as follows: 0.864 and 0.612, 0.782 and 0.653, 0.792 and 0.664, 0.850 and 0.551, 0.867 and 0.664, respectively. Conclusions:The Padua Score demonstrated better predictive efficacy compared to the Simplified Method. However, the Simplified Method had more accessible assessment criteria and could serve as an initial VTE risk screening tool in emergency situations or when complete data are not available.

OBJECTIVETo evaluate the efficacy and safety of meropenem in Chinese patients, we conducted a study for the treatment of patients with lower respiratory tract infections, urinary tract infections and other infections.

METHODSA total of 182 hospitalized patients were enrolled in the study. 90 patients received 500 mg meropenem every 12 hours (or 1 g every 12 hours if necessary) and 92 patients received imipenem/cilastatin 500 mg/500 mg every 12 hours (or 1 g every 12 hours if necessary) by intravenous infusion. The duration of treatment was 7 - 14 days for both groups.

RESULTSSeventy of 90 cases receiving meropenem and 70 of 92 cases receiving imipenem/cilastatin were assessable for clinical efficacy. The overall efficacy rates were 90% for the meropenem group and 87% for the imipenem/cilastatin group, and the bacterial eradication rates were 86% in both groups. 93 (76%) of 123 strains isolated from patients produced beta-lactamases. Adverse drug reactions were evaluated in 72 cases in the meropenem group and 70 cases in the imipenem/cilastatin group. The adverse drug reaction rates were 9.7% and 8.6%, respectively. The results showed that there were no statistical differences between these two groups (P > 0.05).

CONCLUSIONMeropenem is effective and safe for the treatment of bacterial infections caused mainly by beta-lactamase-producing strains.
