Objective:To investigate the high risk factors,diagnostic accuracy of ultrasonography and pregnan-cy outcomes of umbilical cord wrapped around the neck for≥4 loops.Methods:The clinical data of 64 pregnant women with umbilical cord around the neck for≥4 loops(the group with umbilical cord around the neck≥4 loops)in Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology from January 2011 to February 2024 were retrospectively analyzed.At the same time,80 cases with umbilical cord around the neck for 1-2 loops(the group with umbilical cord around the neck 1-2 loops)were randomly selected as the controls.General information,clinical manifestations,ultrasound diagnosis and other data of the two groups were collected.The risk factors of umbilical cord around the neck≥4 loops and diagnostic accuracy of ultrasonography were ana-lyzed with univariate and multivariate Logistic regression analysis,and the pregnancy outcomes were compared between the two groups.Results:①The incidence of pregnancy,abortion,delivery and history of cesarean sec-tion were lower in the group with umbilical cord around the neck ≥4 loops than those in the group with umbilical cord around the neck 1-2 loops.The incidence of consciously abnormal fetal movement,abnormal umbilical ar-tery systolic/diastolic(S/D)ratio,abnormal fetal heart rate monitoring(NST)and fetal distress were higher in the group with umbilical cord around the neck≥4 loops than those in the group with umbilical cord around the neck 1-2 loops,and the differences were statistically significant(P＜0.05).②Multivariate Logistic regression analysis showed that polyhydramnios and excessively long cord were independent risk factors for umbilical cord around the neck≥4 loops(OR＞1,P＜0.05).③When the time between ultrasound diagnosis and the operation was 2 days,the consistency rate between ultrasound diagnosis of umbilical cord around the neck≥4 loops and intrao-perative diagnosis was the highest,and the difference was statistically significant with＞3 days(46.2％vs.6.30％,P＜0.05).Compared with umbilical cord around the neck 3 loops,ultrasound diagnosis of umbilical cord loops around the neck at 4 or 5 loops had a higher consistency rate with intraoperative diagnosis,and the differ-ence was statistically significant(P＜0.05).④The incidence of premature delivery,neonatal asphyxia and admis-sion to neonatology in the group with umbilical cord around the neck ≥4 loops were higher than those in the group with umbilical cord around the neck 1-2 loops,and the difference was statistically significant(P＜0.05);and the gestational week and birth weight of newborns were significantly lower(P＜0.05).Conclusions:Polyhydramnios and excessively long cord are high risk factors for umbilical cord around the neck≥4 loops.The closer the ultra-sound diagnosis is to the time before cesarean section and the more times the umbilical cord is around the neck in ultrasonic diagnosis,the higher the diagnostic accuracy.Fetal outcomes with umbilical cord around the neck≥4 loops are worse.

Objective To describe the changing trend and related factors of prevalence rates of healthcare-associa-ted infection(HAI)in a tertiary hospital in the past 10 years,and analyze the influencing factors for HAI.Methods A cross-sectional survey on HAI was conducted for 10 consecutive years from 2013 to 2022(one day was selected as the survey day each year),data were collected.The distribution and related factors of prevalence rates of HAI were analyzed by trend-x2 test and Pearson correlation coefficient.Multivariate logistic regression and multilayer percep-tron(MLP)models were constructed to analyze the independent effect and significance of factors.Results From 2013 to 2022,the prevalence rates of HAI ranged from 4.66％to 8.07％in this hospital,showing a linear upward trend.The proportions of ICU patients and utilization rate of central venous catheters within 2 days before the sur-vey showed linear upward trends,while the proportion of patients with urinary catheters within 2 days before the survey and proportion of patients undergoing surgery within 30 days before the survey decreased.The MLP model revealed that the top 3 important factors for HAI were length of hospital stay＞10 days,admission in ICU,and in-dwelling central venous catheters within 2 days before the survey.Multivariate logistic regression model indicated that length of hospital stay＞10 days,indwelling central venous catheters or urinary catheters within 2 days before the survey,surgery within 30 days before the survey,and admission in ICU were independent influencing factors for HAI.Conclusion The incidence of HAI in this hospital presents a linear increase in recent 10 years,the causes should be further analyzed and the direction of intervention should be determined through targeted surveillance.Adopting trend test statistical analysis method,logistic regression,MLP multi-factor model can further explore the data value of HAI prevalence survey.

Objective To analyze whether coronavirus disease 2019(COVID-19)is a potential risk for the infec-tion/colonization with multidrug-resistant organisms(MDROs)in hospitalized patients during a surge admission of COVID-19 patients.Methods Data of hospitalized patients in a tertiary first-class hospital from December 1,2022 to January 31,2023 were retrospectively analyzed.Clinical data,antimicrobial therapy,and MDROs detection re-sult between COVID-19 patients and non-COVID-19 patients were compared.Patients with detected pathogens were divided into MDRO group and non-MDRO group.Risk factors for infection/colonization with MDROs in hos-pitalized patients were analyzed by multivariate logistic regression.Results A total of 16 710 patients were admitted in hospital,2 403 cases were in COVID-19 group,and 8.83％(113/1 280)were MDRO-infected cases;14 307 ca-ses were in non-COVID-19 group,and 4.43％(167/3 770)were MDRO-infected cases.The detection rate of car-bapenem-resistant Klebsiella pneumoniae(CRKP)in patients in COVID-19 group was higher than that in non-CO-VID-19 group(48.15％vs 30.89％,P=0.028).Multivariate analysis results showed that critical illness(OR=4.796,95％CI:3.524-6.527),antimicrobial therapy≥2days before pathogen culture(OR=2.330,95％CI:1.699-3.196),positive fungi culture(OR=1.780,95％CI:1.318-2.405),long hospital stay(OR=1.036,95％CI:1.030-1.042)were risk factors for MDRO infection/colonization in hospitalized patients(all P＜0.05).Conclusion During mass admission of COVID-19 patients,MDROs infection/colonization is related to critical ill-ness,antimicrobial use,positive fungi culture and long hospital stay,while COVID-19 infection is not a risk factor for MDROs infection/colonization.
