RESUMO
SUMMARY OBJECTIVE: The aim of this study was to explore the efficacy of imipenem combined with glutamine in the treatment of severe acute pancreatitis with abdominal infection in mainland China using meta-analysis. METHODS: We searched China National Knowledge Network, Wanfang Medical Network, Chinese Science Citation Database, PubMed, and Embase Databases for publications of imipenem combined with glutamine in the treatment of severe acute pancreatitis abdominal infection. The search time limit was from the establishment of the database to April 10, 2021. Stata software version 12.0 was used for statistical analysis; the combined effect size odds ratio and standardized mean difference values were calculated for the count data and measurement data, respectively; and the heterogeneity test was performed in this study. RESULTS: A total of five randomized controlled trials were included. A total of 499 cases were included, with 251 in the observation group and 248 in the control group. Meta-analysis results showed that the efficacy of imipenem combined with glutamine in the treatment of severe acute pancreatitis with abdominal infection was significantly better than that of imipenem alone (odds ratio=0.78, 95%CI 0.71-0.86, p=0.040). CONCLUSION: Imipenem combined with glutamine can significantly improve the efficacy in the treatment of severe acute pancreatitis with abdominal cavity infection.
RESUMO
Objective@#To study the compliance and associated factors of smartphone application (APP) usage in childhood dietary and exercise intervention.@*Methods@#Based on one childhood intervention of diet and exercise in Beijing, Changzhi of Shanxi Province and Urumqi of Xinjiang Province, 694 children (and their primary caregivers) in the intervention group were investigated regarding usage of APP during the intervention. Compliance of APP usage was evaluated by the click times of APP, and Logistic regression models were used to analyze influencing factors of the compliance.@*Results@#The median (inter quartile range) click times of APP in the four modules (information dissemination, behavior monitoring, homework uploading and feedback) were 10 (5，21), 20 (14，26), 7(4，10), 26 (15，53), respectively. Multivariable logistic regression analysis found that compliance of APP usage was higher among subjects in Changzhi region ( OR =1.67，95% CI =1.12-2.48), whose primary caregiver was mother ( OR =1.55，95% CI =1.09-2.22), or whose mother did not work ( OR =0.47， 95% CI =0.31-0.74).@*Conclusion@#Compliance of APP usage was generally high in the childhood intervention of diet and exercise. Some factors are associated with compliance of APP usage. Findings of the study provide a scientific basis for better implementation of APP based childhood interventions of diet and exercise in the future.
RESUMO
Objective@#To study the relationship between nutrition status and physical fitness in 8-10 year-old children in 3 cities, and to provide a scientific reference for improving physical condition of chidren of pre-school age.@*Methods@#To investigate the weight, height and physical fitness (standing long jump, endurance running, rope skipping in one minute and sit-ups in one minute) of 1 384 children in grade four from 24 primary schools in Beijing, Changzhi, Urumchi in 2018. Evaluated overweight and obesity by using the standard of “Screening for Overweight and Obesity among School-age Children”. Then used mixed linear model to compare the physical fitness of students with different nutritional status and to analyze the relationship between BMI and physical fitness.@*Results@#The prevalence of overweight and obesity were 17.41% and 23.48%, respectively. And the prevalence in boys was both more than that in girls(χ2=9.84，47.68，P<0.01). The increase in BMI of children from the same age and the same gender was related with the decrease in physical fitness by correlation analysis(P<0.05). In comparison method, the performance of the students of normal weight was better than obese students, but the male and female students had got the same results in their physical fitness test(P<0.05).@*Conclusion@#There is a negative correlation between nutrition status and physical fitness and the physical fitness in normal weight and obese children are better than the overweight children or obese children.
RESUMO
Objective@#To investigate the incidence of malnutrition in children and adolescents aged between 8 and 16 years in Zhongshan, Guangdong Province and to explore the impact of lower body mass index in early childhood on malnutrition in children and adolescents.@*Methods@#A retrospective cohort of 2 188 students with complete data on weight and height from grade one in primary school to grade one in high school in Zhongshan were included in this analysis. Normal weight individuals with BMI lower than the 50th percentiles (P50) were defined as lower BMI, according to "Report on the Physical Fitness and Health Surveillance of Chinese School Students" in 2005. Screening Standard for Malnutrition of School-age Children and Adolescents in 2014 (WS/T 456—2014) was used to define malnutrition. Prevalence and incidence of malnutrition was calculated, and chi-square test was used to compare the difference of the incidence of malnutrition between children with BMI <P50 and those with BMI ≥P50 at baseline.@*Results@#The prevalence of malnutrition was 15.08% for children in grade one of primary school, which reached highest of 16.32% in grade two of primary school and decreased to 7.27% in grade one in high school. The annual incidence of malnutrition among students with normal weight decreased from 8.37% in grade two in primary school to 1.22% in grade one in high school. Boys with lower BMI in grade one in primary school had the incidence of malnutrition with 12.47% in grade two in primary school, while those with BMI ≥P50 had the incidence of 0.63%. Girls with lower BMI had higher incidence of malnutrition than those with BMI ≥P50.@*Conclusion@#Incident malnutrition between grade one in primary school and grade one in high school is more likely to occur in early childhood. Lower BMI in early childhood significantly increases the risk of malnutrition in children and adolescents. Malnutrition prevention should be implemented from early childhood, especially for those with lower BMI.
