Despite its importance as an indicator for the development of diabeticcomplications, recent studies have revealed that this metric has some limitations; it conveys a rather complex message, which has to be taken into consideration for diabetes screening and treatment. On the basis of recent clinical trials, the relationship between Hb A1 c and cardiovascular outcomes in long-standing diabetes has been called into question. It becomes obvious that other surrogate and biomarkers are needed to better predict cardiovascular diabetes complications and assess efficiency of therapy. Glycated albumin, fructosamin, and 1,5-anhydroglucitol have received growing interest as alternative markers of glycemic control. In addition to measures of hyperglycemia, advanced glucose monitoring methods became available. An indispensible adjunct to Hb A1 c in routine diabetes care is selfmonitoring of blood glucose. This monitoring method is now widely used, as it provides immediate feedback to patients on short-term changes, involving fasting, preprandial, and postprandial glucose levels. Beyond the traditional metrics, glycemic variability has been identified as a predictor of hypoglycemia, and it might also be implicated in the pathogenesis of vascular diabetes complications. Assessment of glycemic variability is thus important, but exact quantification requires frequently sampled glucose measurements. In order to optimize diabetes treatment, there is a need for both key metrics of glycemic control on a day-to-day basis and for more advanced, user-friendly monitoring methods. In addition to traditional discontinuous glucose testing, continuous glucose sensing has become a useful tool to reveal insufficient glycemic management. This new technology is particularly effective in patients with complicated diabetes and provides the opportunity to characterize glucose dynamics. Several continuous glucose monitoring(CGM) systems, which have shown usefulness in clinical practice, are presently on the market. They can broadly be divided into systems providing retrospective or real-time information on glucose patterns. The widespread clinical application of CGM is still hampered by the lack of generallyaccepted measures for assessment of glucose profiles and standardized reporting of glucose data. In this article, we will discuss advantages and limitations of various metrics for glycemic control as well as possibilities for evaluation of glucose data with the special focus on glycemic variability and application of CGM to improve individual diabetes management.展开更多

These modifications include phosphory- lation, methylation, acetylation, ubiqulUnation, SUMOy- lation, and O-GIcNAcylation. Recent studies have shed light on the importance of lysine acetylation at nonhis- tone proteins including transcription factors. Acetyla- tion of transcription factors affects subcellular distribution, DNA affinity, stability, transcriptional activity, and current investigations are aiming to further expand our understanding of the role of lysine acetyla- tion of transcription factors. In this review, we summarize recent studies that provide new insights into the role of protein lysine-acetylation in the transcriptional regulation of metabolic homeostasis.展开更多

METHODS: Using a cross sectional study design, information was obtained by self-administered questionnaires from 300 university individuals. FeMS was defined as any individuals self-reporting at least one of the clinical diagnoses of diabetes, hypertension, hyperlipidemia, or obesity. Finally, two categories were created for cross tabulation, and individuals with and without FeMS were compared. RESULTS: Of the 192 individuals completing the study, 39% (n=76) were currently using or had used CAM therapies in the past 12 months. Individuals with FeMS (n=54, 28%) were more likely (P〈0.05) to use different types of CAM therapies, in particular dietary and herbal supplements, aromatherapy and massage therapy compared to individuals without FeMS (n=138, 72%). CONCLUSION: Individuals with FeMS were more likely to use CAM, particularly supplements. Doctors need to properly inquire about and understand their patients' supplement use, especially if CAM therapies are used in coniunction with conventional medications.展开更多
