ABSTRACT
BackgroundThe incidence of delirium in critically ill psychiatric patients is high， and there are many factors affecting delirium occurrence. At present， epidemiological studies on delirium among critically ill patients in psychiatric hospitals are limited. ObjectiveTo explore the risk factors for delirium in critically ill patients in a psychiatric hospital， so as to guide the clinical management of delirium in psychiatric hospitals. MethodsThis retrospective study included 427 critically ill patients who were admitted to Shenzhen Kangning Hospital from January 1， 2019 to May 31， 2021. The delirium situation， gender， age， pre-admission course of illness （duration from the onset of acute mental state changes to in-patient registration at a psychiatric hospital）， history of mental illness， history of cognitive dysfunction， history of using psychoactive substances， history of using sedative and hypnotic drugs， number of combined chronic diseases， number of combined drugs and type of disease were examined as potential risk factors for delirium. Single Logistic regression was used to analyze the potential risk factors for delirium， and the potential risk factors were incorporated into the multi-factor Logistic regression analysis model so as to gradually screen out the risk factors for delirium in critically ill psychiatric patients. ResultsDelirium was present in 33.49% （143/427） of critically ill patients. Multi-factor Logistic regression analysis demonstrated that the presence of delirium was associated with mental and behavioral disorders caused by psychoactive substances （OR=8.949， P<0.01）， absent history of mental illness （OR=4.202， P<0.01）， number of combined chronic diseases （OR=1.249， P<0.01）， age （OR=1.031， P<0.01） and pre-admission course of illness （OR=0.942， P<0.01） . ConclusionDelirium was present in nearly 1/3 critically ill patients in the psychiatric hospital. The risk factors for delirium included short course of illness before admission， age， more combined chronic diseases， absent history of mental illness， mental and behavioral disorders caused by psychoactive substances. ［Funded by Shenzhen Fund for Guangdong Provincial High-level Clinical Key Specialties （number， SZGSP013）］
ABSTRACT
OBJECTIVE@#To study the expression of IgE in recur repeatedly children otitis media with effusion (OME), and the relativity of IgE between adenoid and middle ear effusion.@*METHOD@#Thirty-five cases diagnosed of OME in our department, were enrolled in the research. Thirty-one adenoidal hypertrophy cases were selected as control group. Obtained middle ear effusion and adenoid samples from experimental group, and obtained adenoid samples from control group. All adenoid samples were taken for tissue homogenate. Determination all samples of concentration of IgE by ELISA. SPSS 18.0 statistical software was used for all relevant data processing and analysis.@*RESULT@#Compared the IgE content between experimental group and control group with adenoid samples, IgE content increased significantly in experimental group (P < 0.05), and IgE in experimental group of middle ear effusion samples were also increased (P < 0.05). The content of IgE in the experimental group of middle ear effusion and adenoid assumed straight-line correlation, in negative correlation (r = 0.580, P < 0.05).@*CONCLUSION@#The occurrence of OME is related to immune factors. Adenoidal hypertrophy may lead to local immunity enhancement, may cause middle ear cavity immune system abnormality, give rise to recur repeatedly with OME and procrastinate does not recover.
