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.

ABSTRACT

Cholestatic liver diseases are important causes of liver cirrhosis and liver transplantation, but few drugs are available for treatment. D-chiro-inositol (DCI), an isomer of inositol found in many Leguminosae plants and in animal viscera, is used clinically for the treatment of polycystic ovary syndrome (PCOS) and diabetes mellitus. In this study, we investigated whether DCI exerted an anti-cholestatic effect and its underlying mechanisms. A cholestatic rat model was established via bile duct ligation (BDL). After the surgery, the rats were given DCI (150 mg·kg-1·d-1) in drinking water for 2 weeks. Oral administration of DCI significantly decreased the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and attenuated bile duct proliferation, parenchymal necrosis and fibrosis in BDL rats. Furthermore, DCI treatment significantly increased the serum and bile levels of total bile acid (TBA), and decreased TBA levels in the liver. Moreover, DCI treatment significantly increased expression of the genes encoding bile acid transporters BSEP (Abcb11) and MRP2 (Abcc2) in liver tissues. DCI treatment also markedly decreased hepatic CD68 and NF-kappaB (NF-κB) levels, significantly decreased the serum and hepatic MDA levels, markedly increased superoxide dismutase activity in both serum and liver tissues. Using whole-genome oligonucleotide microarray, we revealed that DCI treatment altered the expression profiles of oxidation reduction-related genes in liver tissues. Collectively, DCI effectively attenuates BDL-induced hepatic bile acid accumulation and decreases the severity of injury and fibrosis by improving bile acid secretion, repressing inflammation and decreasing oxidative stress. The results suggest that DCI might be beneficial for patients with cholestatic disorders.

ABSTRACT

AIM: To evaluate the protective effect of bicyclol against bile duct ligation (BDL)-induced hepatic fibrosis in rats. METHODS: Sprague-Dawley male rats underwent BDL and sham-operated animals were used as healthy controls. The BDL rats were divided into two groups which received sterilized PBS or bicyclol (100 mg/kg per day) orally for two consecutive weeks. Serum, urine and bile were collected for biochemical determinations. Liver tissues were collected for histological analysis and a whole genome oligonucleotide microarray assay. Reverse transcription-polymerase chain reaction and Western blotting were used to verify the expression of liver fibrosis-related genes. RESULTS: Treatment with bicyclol significantly reduced liver fibrosis and bile duct proliferation after BDL. The levels of alanine aminotransferase (127.7 ± 72.3 vs 230.4 ± 69.6, P < 0.05) and aspartate aminotransferase (696.8 ± 232.6 vs 1032.6 ± 165.8, P < 0.05) were also decreased by treatment with bicyclol in comparison to PBS. The expression changes of 45 fibrogenic genes and several fibrogenesis-related pathways were reversed by bicyclol in the microarray assay. Bicyclol significantly reduced liver mRNA and/or protein expression levels of collagen 1a1, matrix metalloproteinase 2, tumor necrosis factor, tissue inhibitors of metalloproteinases 2, transforming growth factor-ß1 and α-smooth muscle actin. CONCLUSION: Bicyclol significantly attenuates BDL-induced liver fibrosis by reversing fibrogenic gene expression. These findings suggest that bicyclol might be an effective anti-fibrotic drug for the treatment of cholestatic liver disease.

ABSTRACT

<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>

ABSTRACT

BACKGROUND: Many patients who survive a myocardial infarction (MI) remain at risk of sudden cardiac death despite revascularization and optimal medical treatment. We used the modified moving average (MMA) method to assess the utility of T-wave alternans (TWA) and heart rate turbulence (HRT) as risk markers in MI patients with or without diabetes mellitus (DM). METHODS: We prospectively enrolled 248 consecutive patients: 96 with MI (post-MI patients); 77 MI with DM (post-MI + DM patients); 75 controls without cardiovascular disease (group control). Both TWA and HRT were measured on ambulatory electrocardiograms (AECGs). HRT was assessed by two parameters ─ turbulence onset (TO) and turbulence slope (TS). HRT was considered positive when both TO ≥0% and TS ≤2.5 ms/R-R interval were met. The endpoint was cardiac mortality. RESULTS: TWA values differed significantly between MI and controls. Post-MI + DM patients had higher TWA values than post-MI patients (58 ± 21 µV VS 52 ± 18 µV, P = 0.029). Impaired HRT--increased TO and decreased TS were observed in MI patients with or without DM. During follow-up of 578 ± 146 days, cardiac death occurred in ten patients and three of them suffered sudden cardiac death (SCD). Multivariate analysis determined that a HRT-positive outcome [HR (95% CI): 5.01, 1.33-18.85; P = 0.017], as well as the combination of abnormal TWA (≥47 µV) and positive HRT had significant association with the endpoint [HR (95% CI): 9.08, 2.21-37.2; P = 0.002)]. CONCLUSION: This study indicates that AECGs-based TWA and HRT can predict cardiac mortality in MI patients with or without DM. Combined analysis TWA and HRT may be a convenient and useful method of identifying patients at high risk for cardiovascular death.

ABSTRACT

<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>

ABSTRACT

<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>
