“…Such geographic variation in TJR rates has been also reported in other countries such as Australia [33], the United Kingdom [34], Finland [35], and Germany [36]. These differences, which often remain even after adjusting for age [36], have been attributed to various factors, including a lack of consensus regarding the indications for these procedures [24,32]. Individuals with end-stage joint disease may suffer from pain, stiffness, and limitation of movement of joints, but they may also present with radiographic evidence of joint disease [37].…”

“…As a typically useful method, spatial autocorrelation analysis is widely utilized to explore the spatial patterns of incidence or mortality of diseases in terms of Moran's I [17][18][19], which was selected due to its greater statistical power. According to the following formula [20], Moran's I is produced by standardizing the spatial autocovariance by the variance of the data using a measure of the connectivity of the data.…”

Introduction: Dengue is an important public health concern in developing countries. As it is increasingly serious in mainland China, its spatiotemporal variations in this region must be further understood. Methodology: On the basis of the data on dengue cases in 2004-2013 collected from the China Information System for Disease Control and Prevention, examinations of spatiotemporal variations of local, imported, and total dengue cases were conducted to characterize this epidemic at the city scale in China. Results: Local cases in September and October accounted for more than half of the total cases in each year. The cities with more than 50 accumulative local cases were mainly distributed along the southeast coastal areas and southwest border regions of China. In 2004-2013, local dengue transmission (indicated by the number of local cases and the locally infected cities) increased yearly and was closely associated with epidemics (represented by the amount of imported cases and the cities with imported cases). At the city level, local transmission tended to be spatially clustered in the Zhejiang-Fujian coastal area, the Pearl River Delta, and Yunnan-Burma border region, especially in 2005, 2010, 2012, and 2013. Conclusions: The results showed that China's local dengue transmission is spatially and temporally featured, and that the prevalence of this epidemic is mostly related to imported cases from overseas epidemic areas. This study provides useful support for hygiene authorities of central and local governments to take effective measures to prevent and control this disease.

“…TKA is a common surgical procedure with an age-standardized rate varying between 75 operations per 100000 in Norway, 132 operations per 100000 in Germany, 174 per 100000 in Switzerland and 221 per 100000 in the United States [9][10][11][12][13][14]. However, TKA in general is associated with significant postoperative pain [1].…”

Background:Combined epidural analgesia (EA) and patient controlled analgesia (PCA) for postoperative pain control after total knee arthroplasty (TKA) is well established. Previous studies demonstrated the effectiveness of femoral nerve block (FNB) in combination with PCA. This study compares clinical efficiency and adverse events of pain therapy of an established (EA+PCA) and a modified (FNB+PCA) protocol. Methods:A retrospective, single-center cohort study analyzing TKA patients after subarachnoid anesthesia. Matched pair analysis was performed using filters for American Society of Anesthesiologists (ASA) classification, age, gender, height, weight, comorbidities and prior use of analgesics. Surgical technique and postoperative medication protocol were similar in both groups. Primary outcome was postoperative pain on movement assessed by a visual analog scale (VAS) and use of analgesics within 72 hours after surgery. Secondary, incidence of adverse events (postoperative nausea and vomiting, pruritus, urinary retention and hypotension) was examined.Results: From a total of 846 patients, 104 matched pairs were built and analyzed within 72 hours after surgery. Mean VAS scores were similar in patients receiving EA+PCA (2.7 ± 1.1) or FNB+PCA (2.8 ± 1.2). Supplemental opioid administration was higher in EA+PCA patients. Hypotension was more frequent in EA+PCA as in FNB+PCA patients (36 % vs. 12 %). Combined adverse events were more frequent in EA+PCA as in FNB+PCA patients (75 % vs. 58 %). Conclusion: Both FNB+PCA and EA+PCA results in equivalent degrees of analgesia after TKA. Converting an established mode of pain therapy to a modified protocol may decrease incidence of adverse events rather than improve quality of analgesia.
