简介:AbstractBackground:Resting heart rate (RHR) is considered as a strong predictor of total mortality and hospitalization due to heart failure in hypertension patients. Bisoprolol fumarate, a second-generation beta-adrenoreceptor blockers (β-blocker) is commonly prescribed drug to manage hypertension. The present study was to retrospectively evaluate changes in the average RHR and its association with cardiovascular outcomes in bisoprolol-treated coronary artery disease (CAD) patients from the CAD treated with bisoprolol (BISO-CAD) study who had comorbid hypertension.Methods:We performed ad-hoc analysis for hypertension sub-group of the BISO-CAD study (n = 866), which was a phase IV, multination, multi-center, single-arm, observational study carried out from October 2011 to July 2015 across China, South Korea, and Vietnam. Multivariate regression analysis was used to identify factors associated with incidence of composite cardiac clinical outcome (CCCO), the results were presented as adjusted odds ratio (OR) along with 95% confidence interval (CI) and adjusted P value.Results:A total of 681 patients (mean age: 64.77 ± 10.33 years) with hypertension from BISO-CAD study were included in the analysis. Bisoprolol improved CCCOs in CAD patients with comorbid hypertension, with RHR <65 and <70 beats/min compared with RHR ≥65 and ≥75 beats/min, respectively, in the efficacy analysis (EA) set. In addition, it lowered RHR in both intent-to-treat (ITT) and EA groups after 6, 12, and 18 months of treatment. Further, RHR 70 to 74 beats/min resulted in significantly higher risk of CCCOs EA set of patients (adjusted OR: 4.34; 95% CI: 1.19-15.89; P = 0.03). Also, events of hospitalization due to acute coronary syndrome were higher when RHR 69 to 74 beats/min compared to RHR <69 beats/min in ITT patients.Conclusion:Bisoprolol can effectively reduce RHR in Asian CAD patients with comorbid hypertension and hence, improve CCCO without affecting their blood pressure.
简介:AbstractGroup B streptococcus (GBS) is a leading cause of neonatal infection. Maternal vaginal-rectal colonization with GBS during the intrapartum period is a prerequisite for GBS early-onset disease (EOD). The obstetric measures for effective prevention of GBS EOD include universal prenatal screening by vaginal-rectal culture, correct specimen collection and processing, appropriate implementation of intrapartum antibiotic prophylaxis, and coordination with pediatric care providers. It is now recommended to universal screen GBS between 360/7 and 376/7 weeks of gestation and to identify groups of women who are eligible for intravenous intrapartum antibiotic prophylaxis as a means of preventing GBS EOD.

简介:AbstractBrucellosis is a zoonotic disease caused by a number of bacteria in the genus Brucella. In animals, classical Brucella species naturally affiliate with mammals in which they cause epididymitis and orchitis in males and abortion storms in pregnant females. Because Brucella proliferates to a vast number of free organisms in the fetal organs and fluids, abortion plays a key mechanism in disease spread in nature. B. melitensis, B. suis, and B. abortus construct the three most severe zoonotic species and their role in human brucellosis stems from their association with domesticated farm animals in which they strive and transmit the disease. Here we review the relevant literature on genus Brucella, vaccination and diagnostic approaches. Meanwhile, the prevention and control programs based on the combination of vaccination coverage of the population with differentiating serological diagnosis of the infected from vaccinated animals (DIVA) and herd clearance by a test and cull strategy using validated serological tests were discussed.

简介:AbstractBackground:Cystic echinococcosis is one of the most severe helminth zoonosis with a drastic impact on human health and livestock industry. Investigating optimal control strategy and assessing the crucial factors are essential for developing countermeasures to mitigate this disease.Methods:Two compartment models were formulated to study the dynamics of cystic echinococcosis transmission, to evaluate the effectiveness of various control measures, and to find the optimal control strategy. Sensitive analyses were conducted by obtaining PRCCs and contour plot was used to evaluate the effect of key parameters on the basic reproduction number. Based on forward-backward sweep method, numerical simulations were employed to investigate effects of key factors on the transmission of cystic echinococcosis and to obtain the optimal control strategy.Results:The food resources of stray dog and invalid sheep vaccination rate, which are always neglected, were significant to the transmission and control of cystic echinococcosis. Numerical simulations suggest that, the implementation of optimal control strategy can significantly reduce the infections. Improving the cost of health education and domestic dog deworming could not decrease human infections.Conclusions:Our study showed that only a long-term use of the optimal control measures can eliminate the disease. Meanwhile, during the intervention, sheep vaccination and stray dogs disposing should be emphasized ahead of domestic dogs deworming to minimize the control cost. Simultaneously reducing other wild intermediate hosts and strengthening the sheep vaccination as well as disposing the stray dogs would be most effective.

简介:AbstractGlobally, rabies remains a serious threat to public health. In particular, large number of cases continue to be detected in Africa and Asia. China has experienced three major outbreaks with the current epizootic starting in 1990s, peaking in 2007 with 3,300 cases, and consistently decreasing since this point. A key factor of the success in keeping the rabies outbreak under control is the National Public Health Reporting Program that was introduced to coordinate surveillance at provincial and regional levels. Through this program, it is possible to obtain an integrated overview of how rabies was spreading and how various factors were contributing to the outbreak. At the same time, samples have been collected from suspected rabies cases and a subset of positive samples selected for sequencing. In this way, it is possible to investigate the outbreak from a phylogenetic perspective, providing the comprehensive description of a rabies outbreak to date. In this work, we review rabies control efforts over the last 20 years, and show how this integrated approach has led to a deeper characterization of the outbreak and a better understanding of the factors driving the spread of the disease.
