Ultrasound detection of sub-clinical atherosclerosis (ATS) may help identify individuals at high cardiovascular risk. Most studies evaluated intima-media thickness (IMT) at carotid level. We compared the relationships between main cardiovascular risk factors (CVRF) and five indicators of ATS (IMT, mean and maximal plaque thickness, mean and maximal plaque area) at both carotid and femoral levels. Ultrasound was performed on 496 participants aged 45-64 years randomly selected from the general population of the Republic of Seychelles. 73.4 % participants had ≥ 1 plaque (IMT thickening ≥ 1.2 mm) at carotid level and 67.5 % at femoral level. Variance (adjusted R2) contributed by age, sex and CVRF (smoking, LDL-cholesterol, HDL-cholesterol, blood pressure, diabetes) in predicting any of the ATS markers was larger at femoral than carotid level. At both carotid and femoral levels, the association between CVRF and ATS was stronger based on plaque-based markers than IMT. Our findings show that the associations between CVRF and ATS markers were stronger at femoral than carotid level, and with plaque-based markers rather than IMT. Pending comparison of these markers using harder cardiovascular endpoints, our findings suggest that markers based on plaque morphology assessed at femoral artery level might be useful cardiovascular risk predictors.

The study considered the discrepancy between the official status and real position of Russian provincial officialdom in the middle of the 19th century. The law was not entirely coherent in all aspects of the officials' life and activity, with ordinary deviations from the law being adopted in practice and accepted, albeit not openly, by the public and sometimes even by the authorities. The main law determining the rights and duties of governors was never followed to the letter and in reality governors' activities were determined by the common (unwritten) law existing in the governmental sphere. The volume and nature of the governors' rights depended on a range of factors, with specific regional features and the governor's personal qualities having a particular significance. The standard of living of government clerks was much higher than their official salary would permit and Matkhanova studied the most widespread cases of abuse, identifying those positions in the administration which offered the most opportunities for such abuses. At the start of the period and on the eve of the reforms public opinion towards the bribery of officials underwent a change. From the late 1850s onwards, there appeared among provincial officials a group of young well-educated clerks with liberal ideas and a new system of moral values which did not allow them to accept bribes or infringe the law in any way. There was also a non-official hierarchy side by side with the legally existing one. A significant role in governing the region, and one which has been underestimated by historians, was played by the head of the governor's office, but the reforms of the 1860s contributed to changing this state of affairs.
