Analysis of risk factors for delirium in critically ill patients in a psychiatric hospital： a retrospective study / 四川精神卫生

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）］

Gender disparity in early death after ST-elevation myocardial infarction / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Females with acute myocardial infarction (AMI) have a higher risk of adverse outcomes because of receiving less evidence-based medical care. Our aim was to investigate the gender disparity in early death after ST-elevation myocardial infarction (STEMI) in the current era.</p><p><b>METHODS</b>A total of 1429 consecutive patients with STEMI in the Liaoning district were analyzed. We compared hospital care and cardiac event data by sex for in-patients with acute STEMI within 24 hours of symptom onset.</p><p><b>RESULTS</b>In the emergency reperfusion group (n = 754), in-hospital mortality occurred in 4.2% of the males and 11.2% of the females (P = 0.001). In the non-emergency reperfusion group (n = 675), in-hospital mortality occurred in 13.0% of the males and 22.9% of the females (P = 0.001). Multivariate Logistic regression analysis revealed female sex as an independent risk factor of death for STEMI patients during hospitalization (OR = 1.691, P = 0.007). After controlling for patients who died within 24 hr after admission, female sex was no longer an independent risk factor (OR = 1.409, P = 0.259).</p><p><b>CONCLUSION</b>Female sex was an independent risk factor for in-hospital mortality of STEMI patients, which is explained by an excess of very early deaths.</p>

Effect of high-dose rosuvastatin loading before percutaneous coronary intervention in female patients with non-ST-segment elevation acute coronary syndrome / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Early loading statin therapy before percutaneous coronary intervention (PCI) is associated with reduced mortality and periprocedural myocardial injury. The aim of this study was to study the effect of rosuvastatin loading therapy before PCI in female patients with non-ST-segment elevation acute coronary syndrome (NSTEACS).</p><p><b>METHODS</b>Consecutive 117 female patients with NSTEACS were randomly assigned to either the group of rosuvastatin loading before PCI (20 mg 12 hours before angioplasty procedure, with a further 10 mg dose 2 hours before procedure, the loading dose group, n = 59) or the no rosuvastatin treatment group before PCI (control group, n = 58). Periprocedural myocardial injury, periprocedural changes of high sensitivity C-reactive protein (hs-CRP), interleukin (IL)-1, IL-6, and tumor necrosis factor (TNF)-a in serum and the incidence of major adverse cardiac events (MACE) 3 months and 6 months later were assessed.</p><p><b>RESULTS</b>The incidence of periprocedural myocardial injury was higher in control group than loading dose group (CKMB: 10.17% vs. 25.86%, P = 0.027; Troponin I: 11.86% vs. 29.31%, P = 0.019). MACE occurred in 1.69% of patients in loading dose group and 12.07% of those in control group 3 months after procedure (P = 0.026), 3.39% vs. 17.24% at 6 months (P = 0.014). The levels of hs-CRP, IL-1, IL-6, and TNF-a in serum were not significantly different between the two groups before PCI, but after PCI they were significantly higher in control group.</p><p><b>CONCLUSIONS</b>High-dose rosuvastatin loading before PCI significantly reduced periprocedural myocardial injury and periprocedural inflammation cytokines release and improved 3-month and 6-month clinical outcomes in female patients with NSTEACS who underwent PCI.</p>

Prospective multi-center study of female patients with ST-elevation myocardial infarction in Liaoning province, China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>In cardiology, it is controversial whether gender influences prognosis after acute myocardial infarction (MI). We examined the 30-day and 1-year prognosis for female patients with ST-elevation myocardial infarction (STEMI) in Liaoning province, and we analyzed factors that influenced these outcomes.</p><p><b>METHODS</b>This was a prospective, multicenter, observational study in which patient data were collected by questionnaire at the time of diagnosis and at approximately 30 days and 1 year later by telephone inquiries. Patients were diagnosed with STEMI between June 1, 2009 and June 1, 2010 at any of the 20 hospitals that gave treatment representative of current STEMI treatment in Liaoning Province. Unified follow-up questionnaire was used to visit the STEMI patients.</p><p><b>RESULTS</b>We analyzed data from a total of 1429 consecutive patients with STEMI in Liaoning province. Female patients were older (70.0 vs. 60.3, P < 0.001) and were less likely to receive emergency reperfusion therapy than male ones (39.2% vs. 58.0%, P < 0.001). Female gender was associated with higher unadjusted 30-day mortality rates (HR = 2.118, 95%CI: 1.572 - 2.854, P < 0.001) and higher unadjusted 1-year mortality rates (HR = 2.174, 95%CI: 1.659 - 2.848, P < 0.001). Multivariate Cox regression analysis showed that female gender was not an independent predictor of 30-day mortality rates (HR = 1.273, 95%CI: 0.929 - 1.745, P = 0.133) nor of 1-year mortality rates (HR = 1.112, 95%CI: 0.831 - 1.487, P = 0.475).</p><p><b>CONCLUSIONS</b>Women with STEMI appear to be at increased risk of 30-day and 1-year mortality compared with male STEMI patients, but this difference may be explained by older age and less frequent receipt of reperfusion therapy among the women.</p>
