ABSTRACT
ObjectiveTo investigate the status of different antiretroviral therapy（ART） initiation times in patients with HIV/AIDS and analyze the relevant characteristics and influencing factors of delayed ART. MethodsFrom December 2018 to December 2020， a survey was conducted among adult HIV/AIDS patients treated in 28 designated AIDS prevention and treatment institutions in Beijing， Shanghai， Guangdong， Jiangsu， Henan， Jiangxi， Guangxi， Yunnan and other places. Data of the basic demographic information， lifestyle and chronic disease prevalence， and characteristics of diagnosis and treatment were collected. The characteristics and related factors of delayed ART were compared and analyzed. ResultsThe median age of 1 741 patients was 41 years old （IQR： 32‒52）. The initial CD4 count of most patients was less than 200 cells·μL-1（51.4%）. Among them， 1 027 patients had delayed ART （59.0%）， and the association between ART initiation time and initial CD4 count varied with the time of diagnosis of HIV infection. Multivariate logistic analysis showed that the older age （aOR=0.99， 95%CI： 0.98‒0.99） was associated with a higher rate of starting ART within 1 month after diagnosis， while those diagnosed before 2017 and with the initial CD4 count >200 cells·μL-1 were more likely to delay ART. Delayed initiation of ART may be a risk factor for poor sleep quality and co-infection in HIV/AIDS patients. ConclusionWith the expansion of free ART in China， the proportion of delayed ART with HIV/AIDS shows a downward trend. Timely ART management should be strengthened for the young HIV/AIDS patients and patients with high CD4 counts.
ABSTRACT
OBJECTIVES@#To study the influence of enteral feeding initiation time on intestinal flora and metabolites in very low birth weight (VLBW) infants.@*METHODS@#A total of 29 VLBW infants who were admitted to the Department of Neonatology, Children's Hospital of Chongqing Medical University, from June to December, 2020, were enrolled as subjects. According to the enteral feeding initiation time after birth, the infants were divided into two groups: <24 hours (n=15) and 24-72 hours (n=14). Fecal samples were collected at weeks 2 and 4 of hospitalization, and 16S rDNA high-throughput sequencing and gas chromatography-mass spectrometry were used to analyze the microflora and short-chain fatty acids (SCFAs) respectively in fecal samples.@*RESULTS@#The analysis of microflora showed that there was no significant difference between the two groups in Chao index (reflecting the abundance of microflora) and Shannon index (reflecting the diversity of microflora) at weeks 2 and 4 after birth (P>0.05). The analysis of flora composition showed that there was no significant difference in the main microflora at the phylum and genus levels between the two groups at weeks 2 and 4 after birth (P>0.05). The comparison of SCFAs between the two groups showed that the <24 hours group had a significantly higher level of propionic acid than the 24-72 hours group at week 4 (P<0.05), while there was no significant difference in the total amount of SCFAs and the content of the other SCFAs between the two groups (P>0.05).@*CONCLUSIONS@#Early enteral feeding has no influence on the diversity and abundance of intestinal flora in VLBW infants, but enteral feeding within 24 hours can increase the level of propionic acid, a metabolite of intestinal flora.

Objective To discuss the related factors influencing the initiation time of forensic psychiatric assessment by analysis of the initiation time of forensic psychiatric assessment of criminal cases in Hunan Province. Methods Related data in assessment files of criminal cases accepted by 8 forensic psychiatric assessment institutions in Hunan Province from January 1, 2011 to December 31, 2016 were extracted. The Logistic regression analysis was used to explore the factors influencing the initiation time of forensic psychiatric assessment. After using property score matching （PSM） to control the influence of confounding factors, the efficiency of public security organs to initiate assessments of suspects with （without） mental disorders and with （without） responsibilities were compared. Results A total of 4 346 cases were included. The Logistic regression analysis suggested that the factors independently related to the initiation time of assessment include： cause of assessment, nationality of the assessed, history of diagnosis and treatment of mental illnesses, history of crimes, history of drug abuse, and status of alcohol consumption before the crime （all P<0.05）. The initiation time of assessment of suspects diagnosed with mental disorder was shorter than those with none （P<0.05）; the initiation time of assessment of suspects without criminal responsibility was shorter than those with responsibility （P<0.05）. After using PSM to control confounding factors, the differences above still existed. Conclusion The cause of assessment, nationality of the assessed, history of diagnosis and treatment of mental illnesses, history of crimes, history of drug abuse, and status of alcohol consumption before the crime are factors that influence the efficiency of public security organs to initiate forensic psychiatric assessments. Under the current assessment initiation mode, forensic psychiatric assessment of suspects who have mental disorders, especially those with no responsibility may be given priority to initiate.
