Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Objective:To investigate the effect of early enteral nutrition on intestinal function in patients with complicated intra-abdominal infection.Methods:In this study,a prospective single-center randomized controlled trial was used to select 88 patients with severe abdominal infections in the surgical intensive care ward from January 2021 to December 2023.Among them,65 patients were eligible and were randomly divided into 33cases in the intervention group(who received early enteral nutrition),and 32cases in the control group(who did not receive early enteral nutrition).The clinical baseline characteristics of the two groups,conditions such as abdominal distension and diarrhea during enteral nutrition,intra-abdominal pressure,the time to reach the standard of complete enteral nutrition,and the indexes of pre-albumin,CRP,and leukocyte count on the third and the seventh day postoperative day were observed.The t-test was used to compare between groups for normally distributed measures.The Mann-Whitney U test was used to compare between groups for skewed measures.The χ2 test or continuity-corrected χ2 test was used to compare the count data between groups.Repeated measures data were analyzed by repeated measures ANOVA.Results:The clinical baseline characteristics of the two groups were completely matched;There were significant differences in the changes of intra-abdominal pressure over time between the two groups(Fgroup=9.665,P=0.004),There were significant differences in the changes of intra-abdominal pressure over time between the two intervention group(Ftime=64.124,P<0.001)and the control group.and the trend of intra-abdominal pressure reduction in the intervention group was more significant than that in the control group(Finteractive=3.938,P=0.023);The time required for the recovery of bowel sounds was significantly shorter in the experimental group than in the control group[(19.5±3.5)h vs(35.3±4.5)h,P<0.001,t=15.829];there was no significant difference in the frequency of abdominal distention,vomiting and aspiration between the two groups(P>0.05),and the difference in the frequency of diarrhea was statistically significant(P=0.003);The time to reach the standard of enteral nutrition in the intervention group was shorter than that in the control group[(6.3±1.2)d vs(7.4±1.5)d,P=0.002];The total hospital stay of the intervention group was significantly shorter than that of the control group[(11±3.2)d vs(14±4.1)d,P=0.007].The prealbumin(0.21±0.2,0.28±0.2)g/L,CRP(175.5±23.6,45.4±14.5)mg/L,and white blood cell count(11.7±2.9,9.1±3.5)109/L of the intervention group on the 3rd and 7th days after surgery were significantly improved compared with those of the control group(P<0.05).Conclusion:Early enteral nutrition can effectively promote the recovery of intestinal function in patients with complicated intra-abdominal infection.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
