Background Elevated fibrinogen (Fg) level is a known risk factor for ischemic stroke. There are few clinical trials on oral fibrinogen-depleting therapies for secondary ischemic stroke prevention. We aimed to assess the effects of one-year therapy with oral lumbrokinase enteric-coated capsules on secondary ischemic stroke prevention. Methods This is a multicenter, randomized, parallel group and controlled study that began treatment in hospitalized patients with ischemic stroke and continued for 12 months. Patients were randomized to either the control group that received the standard stroke treatment or the fibrinogen-depleting group that received the standard stroke treatment plus enteric-coated lumbrokinase capsules. The NIH Stroke Scale scores (NIHSSs) and plasma Fg level were recorded. The carotid artery intima-media thickness (IMT) and status of plaques were examined through carotid ultrasound examination. Primary outcomes included all-cause mortality, any event of recurrent ischemic stroke/transient ischemic attack (TIA), hemorrhagic stroke, myocardial infarction and angina, and other noncerebral ischemia or hemorrhage. Kaplan-Meier survival analysis and the Long-rank test were used to compare total vascular end point incidence between the two groups. Comparison of median values between two groups was done by the Student t test, one-way analysis of variance (ANOVA), or non-parametric rank sum test. Results A total of 310 patients were enrolled, 192 patients in the treatment group and 118 patients in the control group. Compared to the control group, the treatment group showed favorable outcomes in the Fg level, carotid IMT, the detection rate of vulnerable plaques, the volume of carotid plaques, NIHSS scores, and incidence of total vascular (6.78% and 2.08%, respectively) and cerebral vascular events (5.93% and 1.04%, respectively) (P <0.05). In the treatment group, the volume of carotid plaques was significantly related to the carotid IMT, the plaque diameter, width and number (P=0.000, 0.000, 0.000, 0.022; F=13.51, 2.52, 11.33, -3.29, but there was a weak correlation with the Fg level (P=0.056). After 1-year therapy, the incidence of overall vascular end points was reduced by 4.7%. Conclusion Long-term oral fibrinogen-depleting therapy may be beneficial for secondary ischemic stroke prevention. Source

Pressure ulcers are very common in hospital patients. Though many studies have been reported in many countries, the large-scale benchmarking prevalence of pressure ulcers in China is not available. The aim of this study is to quantify the prevalence of pressure ulcers and the incidence of hospital-acquired pressure ulcers and analyze risk factors in hospitalized patients in China. A multi-central cross-sectional survey was conducted in one university hospital and 11 general hospitals in China. The Minimum Data Set (MDS) recommended by European Pressure Ulcer Advisory Panel (EUPAP) was used to collect information of inpatients. All patients stayed in hospital more than 24 hours and older than 18 years signed consent form and were included. Data from 39952 out of 40415 (98.85%) inpatients were analyzed. Of the 39952 patients, 631 patients (including 1024 locations) had pressure ulcers. The prevalence rate of pressure ulcers in 12 hospitals was 1.58% (0.94-2.97%). The incidence of hospital-acquired pressure ulcers (HAPU) was 0.63% (0.20-1.20%). The most common locations developed pressure ulcers were sacrum, heels, and iliac crests. The common stages of pressure ulcers were stage I and II. Patients in Intensive Care Unit, Geriatric and Neurological Department were easier to develop pressure ulcers. The prevalence and incidence of pressure ulcers in China was lower than that reported in European and other countries. The stages of pressure ulcers in China were different than that reported in European countries. Our study provides with a baseline value for intensive research on pressure ulcer in China. Source

Background: Retinal vein occlusion (RVO) is a common retinal vascular disease and it is one of the most frequently reported causes of visual damage and blindness in the elderly. The current study investigated the potential association between antiphospholipid antibodies (APLA) and RVO risk by conducting a meta-analysis of case-control studies. Methods: A systematic literature search of Pubmed and Embase databases was conducted in August 1st, 2014. Odds ratios (ORs) were used to evaluate the associations between APLA and the incidence of RVO. A random-effects model was obtained for the quantitative synthesis. Results: A total of 11 studies were included in this meta-analysis. A meta-analysis of all studies assessing the risk of RVO revealed that APLA was associated with a statistically increased risk of RVO incidence (OR = 5.18, 95% CI = [3.37, 7.95]). The association between anticardiolipin antibodies (ACA) and the risk of RVO was significant (n =8, OR = 4.59, 95% CI = [2.75, 7.66]). However, the association between lupus anticoagulants (LA) and risk of RVO was non-significant (n = 5, OR = 3.90, 95% CI = [0.99, 15.37]). No significant publication bias was found in the 11 selected studies. Conclusion: APLA was significantly associated with the risk of RVO. Advanced analyses showed that ACA rather than LA affected the risk of RVO. Additional well-designed and well-conducted epidemiological studies are required to further our understanding of the relationship between APLA and RVO risk. © 2015 Zhu et al. Source
