Trend of cross-sectional survey results of healthcare-associated infection in Wuhan City from 2016 to 2020 / 中国感染控制杂志

Objective To understand the current situation of healthcare-associated infection(HAI)and communi-ty-associated infection(CAI)in medical institutions in Wuhan City,and analyze the epidemic trend and key manage-ment of HAI.Methods The combination of medical record and bedside survey was adopted to conduct a survey ac-cording to the table of cross-sectional survey formulated by National HAI Monitoring and Management Training Base.Survey data from 2016,2018,and 2020 were analyzed.Results HAI prevalence rates in Wuhan City in 2016,2018,and 2020 were 2.66％,2.21％,and 1.85％,respectively.CAI prevalence rates were 17.81％,17.82％,and 16.29％,respectively.Both showed decreasing trends(both P＜0.05).Departments with high pre-valence rates of HAI were the intensive care unit(ICU),departments(groups)of hematology,neurosurgery,tho-racic surgery,and pediatric neonatal.Departments with high prevalence rates of CAI were the departments(groups)of pediatric non-neonatal,respiratory diseases,infectious diseases,general ICU,and pediatric neonatal.The main infection sites of HAI and CAI were lower respiratory tract.The proportions of postoperative HAI at lower respiratory tract in 2016,2018,and 2020 were 12.85％,18.39％,and 22.09％,respectively.HAI rates at surgical site in 2016,2018,and 2020 were 0.99％,0.82％,and 0.69％,respectively.HAI and CAI were mainly caused by Gram-negative bacteria.Conclusion The management of HAI in medical institutions in Wuhan City in 2016,2018,and 2020 have made achievements.However,infection control in general ICU and of HAI at lower respiratory tract still need to be strengthened and improved.

Analysis of risk factors for severe illness caused by coronavirus disease 2019 in Fuzhou city / 解放军医学杂志

Objective To analyze the risk factors for severe illness caused by coronavirus disease 2019 in Fuzhou city.Methods The data of 4081 confirmed cases with current address in Fuzhou was collected from China Information System for Disease Control and Prevention from January 1 to June 30,2023.The epidemiological data of those cases was investigated such as the demographic characteristics,clinical manifestations and past medical history,etc.The risk factors of severe cases were analyzed by using the logistic regression.Results 4081 confirmed cases had been reported including 671 severe cases and 3410 non-severe cases.The demographic characteristics of severe cases,such as the proportion of male,age and current address in community were higher than that of non-severe cases,vaccination rate was lower than non-severe cases(59.02%vs.80.12%),the differences are statistically significant(P＜0.001).The clinical manifestations such as interval time between onset and visit(P=0.001),fever(P=0.002),difficulty in breathing/shortness of breath(P=0.001)were the factors related to severe illness.The past medical histories such as history of chronic lung disease,history of heart cerebrovascular disease of severe cases,were higher than that of non-severe cases(P＜0.001).Multivariate logistic regression showed that the male,the higher age,current address in community,no vaccination,the longer interval time between onset and visit,fever,difficulty in breathing/shortness of breath,the history of chronic lung disease,the history of heart cerebrovascular disease raised the risk of becoming severe cases.The healing time for severe cases was longer than that for non-severe cases(P＜0.001).Conclusion Sex,age,current address,vaccination,interval time between onset and visit,fever,difficulty in breathing/shortness of breath,history of chronic lung disease,and history of heart cerebrovascular disease are the influencing factors for severe illness.

Subchronic Oral Toxicity Evaluation of Lanthanum: A 90-day, Repeated Dose Study in Rats / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>The present study was undertaken to evaluate the subchronic toxicity of lanthanum and to determine the no observed adverse effect level (NOAEL), which is a critical factor in the establishment of an acceptable dietary intake (ADI).</p><p><b>METHODS</b>In accordance with the Organization for Economic Co-operation and Development (OECD) testing guidelines, lanthanum nitrate was administered once daily by gavage to Sprague-Dawley (SD) rats at dose levels of 0, 1.5, 6.0, 24.0, and 144.0 mg/kg body weight (BW) per day for 90 days, followed by a recovery period of 4 weeks in the 144.0 mg/kg BW per day and normal control groups. Outcome parameters were mortality, clinical symptoms, body and organ weights, serum chemistry, and food consumption, as well as ophthalmic, urinary, hematologic, and histopathologic indicators. The benchmark dose (BMD) approach was applied to estimate a point of departure for the hazard risk assessment of lanthanum.</p><p><b>RESULTS</b>Significant decreases were found in the 144.0 mg/kg BW group in the growth index, including body weight, organ weights, and food consumption. This study suggests that the NOAEL of lanthanum nitrate is 24.0 mg/kg BW per day. Importantly, the 95% lower confidence value of the benchmark dose (BMDL) was estimated as 9.4 mg/kg BW per day in females and 19.3 mg/kg BW per day in males.</p><p><b>CONCLUSION</b>The present subchronic oral exposure toxicity study may provide scientific data for the risk assessment of lanthanum and other rare earth elements (REEs).</p>

Effect of Bubble Bath Coordinating with Functional Training on the Children with Spastic Cerebral Palsy / 中国康复理论与实践

@#ObjectiveTo observe the effect of bubble bath coordinating with functional training on the children with spastic cerebral palsy.Methods210 children with spastic cerebral palsy were randomly divided into the treatment group (n=118) and control group (n=92). All children were treated with functional training, acupuncture and other physical therapies. Children in the treatment group were added with bubble bath one time every day, twenty days as one course. Muscular tension was evaluated with modified Ashworth Scale and range of motion was measured before and after treatment.ResultsIn the treatment group, 55 cases were significant, 53 cases were effective, 10 cases were invalid, the total effective rate was 91.5%; in the control group, 26 cases were significant, 46 cases were effective, 20 cases were invalid, the total effective was 78.2%. There was a significant difference between the total effective rates of two groups (P<0.05).ConclusionBubble bath can significantly decrease the muscular tension of children with spastic cerebral palsy.

Clinical study of auditory nerve pathway injury complicated with cerebral palsy / 中华物理医学与康复杂志

Objective To investigate the incidence of auditory nerve pathway injury complicated with cere- bral palsy(CP) and its related factors relationship between the incidence rate of it and sexes,classification and risk factors. Methods The clinical data of 272 children with CP,including the data of brainstem auditory evoked po- tentials,were retrospectively reviewed.The incidence of auditory nerve pathway injury and the related factors were analyzed.Results In the 272 CP children,the incidence of auditory nerve pathway injury was 29.8% (81:272), which had a significantly relationship with the clinical types of CP (P0.05).In addition,it was found that the pathological jaundice (OR=2.945,95% CI:1.649-5.260) and intrauterine infection (OR=3.319,95% CI:1.037-10.625) were significantly related to auditory nerve pathway injury. Conclusion The auditory nerve pathway injury is common in CP children,especially in those with athetosis and mixed CP.Pathological jaundice and intrauterine infection are the risk factors of auditory nerve pathway injury.
