Objective
We aimed to investigate the effect of known heart disease on post‐out‐of‐hospital cardiac arrest (OHCA) survival outcomes, and its association with factors influencing survival.Methods
This was an observational, retrospective study involving an OHCA database from seven Asian countries in 2009–2012. Heart disease was defined as a documented diagnosis of coronary artery disease or congenital heart disease. Patients with non‐traumatic arrests for whom resuscitation was attempted and with known medical histories were included. Differences in demographics, arrest characteristics and survival between patients with and without known heart disease were analysed. Multivariate logistic regression was performed to identify factors influencing survival to discharge.Results
Of 19 044 eligible patients, 5687 had known heart disease. They were older (77 vs 72 years) and had more comorbidities like diabetes (40.9 vs 21.8%), hypertension (60.6 vs 36.0%) and previous stroke (15.2 vs 10.1%). However, they were not more likely to receive bystander cardiopulmonary resuscitation (P = 0.205) or automated external defibrillation (P = 0.980). On univariate analysis, known heart disease was associated with increased survival (unadjusted odds ratio 1.16, 95% confidence interval 1.03–1.30). However, on multivariate analysis, heart disease predicted poorer survival (adjusted odds ratio 0.76, 95% confidence interval 0.58–1.00). Other factors influencing survival corresponded with previous reports.Conclusions
Known heart disease independently predicted poorer post‐OHCA survival. This study may provide information to guide future prospective studies specifically looking at family education for patients with heart disease and the effect on OHCA outcomes. 相似文献2.

Melioidosis is a fatal disease caused by Burkholderia pseudomallei. Currently there is no vaccine available. Synthetic oligodeoxynucleotides with unmethylated CpG dinucleotide motifs (CpG ODN) can stimulate vertebrate immune cells and clear certain pathogens that are susceptible to a strong Th1 response. In our previous study, pretreatment with CpG ODN alone or CpG-ODN with cationic liposomes for 2–10 or 30 days before B. pseudomallei infection in mice conferred 80–100% protection. In the present study we investigated the protective effect of CpG-ODN together with heat-killed (HK) or paraformaldehyde-killed B. pseudomallei (PP). HK or PP were used to immunize BALB/c mice twice at 15-day intervals before intra-peritoneal challenge with 5LD50 of B. pseudomallei and observed for 30 days. We found that PP could significantly protect mice (60%) with an increased survival time (24.8 ± 11.63 days) while in the HK and PBS groups, all infected mice died within 6 days. Although either CpG ODN or PP conferred significant protection, giving them in combination did not enhance it further. Serum IFN-γ levels on day-5 (before challenge) of the PP and PP + CpG ODN groups were significantly higher than those of the PBS control group. The results further support the importance of IFN-γ in host protection against B. pseudomallei and suggest further study on paraformaldehyde-killed bacteria as a component of a future B. pseudomallei vaccine. 相似文献

IL-1β is known as a pro-inflammatory cytokine and plays a pivotal role in regulating immune response. IL-1β has been shown to influence immune responses in Japanese flounder Paralichthys olivaceus. To investigate the immune responses, a plasmid construct of pcDNA3.1-driven Japanese flounder IL-1β (pcDNA3.1-JFIL-1β) was co-injected into the muscle with Bovine serum albumin (BSA), as an antigen model, or pCI-neo driven with GFP (pCI-neo-GFP) as a vaccine model compared with the antigen or vaccine model alone, respectively. The IL-1β expression in the muscle was dramatically elevated in fish injected with pcDNA3.1-JFIL-1β on a day after injection, and the induction level was significantly higher than control groups. Moreover, pcDNA3.1-JFIL-1β significantly stimulated the gene expression of IL-1β in the kidney. The pcDNA3.1-JFIL-1β enhanced the antibody titer against BSA at 30 days after injection. In the DNA vaccine model, the antibody titer against GFP was also higher in the fish injected with pcDNA3.1-JFIL-1β than the group that injected pCI-neo-GFP alone. These results suggest that the pcDNA-driven Japanese flounder IL-1β could have potential immunoadjuvant effects. 相似文献

Melioidosis is a severe disease caused by the Gram-negative bacterium Burkholderia pseudomallei. Previously we showed that pretreatment of mice with CpG oligodeoxynucleotide (CpG ODN) 2 to 10 days prior to B. pseudomallei challenge conferred as high as 90% protection, but this window of protection was rather short. In the present study, we therefore aimed to prolong this protective window and to gain further insight into the mechanisms underlying the protection induced by CpG ODN against B. pseudomallei infection. It was found that the CpG ODN incorporated with cationic liposomes (DOTAP) but not zwitterionic liposomes (DOPC) provided complete protection against bacterial challenge. Although marked elevation of gamma interferon (IFN-γ) was found in the infected animals 2 days postinfection, it was significantly lowered by the DOTAP-plus-CpG ODN pretreatment. When appropriately activated, the phagocytic index and oxidative burst responses of neutrophils appeared not to be elevated. However, macrophages from stimulated mice showed higher levels of nitric oxide production and exhibited higher levels of antimicrobial activities, judging from lower numbers of viable intracellular bacteria. Taken together, our results demonstrate that DOTAP can enhance the protective window period of CpG ODN to at least 30 days and provide 100% protection against B. pseudomallei infection. The protective effect of DOTAP plus CpG ODN could provide an alternative approach to preventing this lethal infection, for which no vaccine is yet available. 相似文献

Although our previous study revealed an association between prolactin level and risperidone dosage, data regarding the plasma concentration of risperidone are lacking. Therefore, this study aimed to investigate the association between plasma drug concentrations of risperidone, 9‐hydroxyrisperidone and serum prolactin level in Thai children and adolescents with autism spectrum disorder (ASD). The individuals for this study were 103 children and adolescents with ASD (90 males and 13 females). In the 12th hour after the last risperidone dose, blood samples were collected for analysis. Serum prolactin, plasma risperidone and 9‐hydroxyrisperidone levels were measured. Patients' clinical data were collected from medical records – age, weight, height, body mass index, dose of risperidone and duration of treatment. Serum prolactin level was significantly positively correlated with plasma 9‐hydroxyrisperidone level (rs = 0.355, p < 0.001). The median concentration of 9‐hydroxyrisperidone in individuals with hyperprolactinaemia (7.59 ng/ml; IQR 4.86–15.55) was significantly higher than non‐hyperprolactinaemic individuals (5.18 ng/ml; IQR 2.10–8.99) after risperidone treatment (p = 0.006). By multivariate analysis, high prolactin level was correlated to high 9‐hydroxyrisperidone level (p = 0.010). The results of this study showed that serum prolactin levels, especially in autistic individuals with hyperprolactinaemia during risperidone treatment, were significantly correlated with the level of 9‐hydroxyrisperidone. These results suggest that hyperprolactinaemia may develop during risperidone treatment. 相似文献
