National Standards for Diabetes Self-Management Education and Support

Abstract: By the most recent estimates, 18.8 million people in the U.S. have been diagnosed with diabetes and an additional 7 million are believed to be living with undiagnosed diabetes. At the same time, 79 million people are estimated to have blood glucose levels in the range of prediabetes or categories of increased risk for diabetes. Thus, more than 100 million Americans are at risk for developing the devastating complications of diabetes (1). Diabetes self-management education (DSME) is a critical element of care for all people with diabetes and those at risk for developing the disease. It is necessary in order to prevent or delay the complications of diabetes (2–6) and has elements related to lifestyle changes that are also essential for individuals with prediabetes as part of efforts to prevent the disease (7,8). The National Standards for Diabetes Self-Management Education are designed to define quality DSME and support and to assist diabetes educators in providing evidence-based education and self-management support. The Standards are applicable to educators in solo practice as well as those in large multicenter programs—and everyone in between. There are many good models for the provision of diabetes education and support. The Standards do not endorse any one approach, but rather seek to delineate the commonalities among effective and excellent self-management education strategies. These are the standards used in the field for recognition and accreditation. They also serve as a guide for nonaccredited and nonrecognized providers and programs. Because of the dynamic nature of health care and diabetes-related research, the Standards are reviewed and revised approximately every 5 years by key stakeholders and experts within the diabetes education community. In the fall of 2011, a Task Force was jointly convened by the American Association of Diabetes Educators (AADE) and the American Diabetes Association …

Too engaged? A conservation of resources view of the relationship between work engagement and work interference with family.

Abstract: In a number of studies, researchers interested in positive organizational behavior have sought to better understand the favorable aspects of work engagement-a pervasive state of emotional attachment and motivation toward work In this study, however, we investigate a potentially negative outcome of engagement Drawing upon conservation of resources theory, we hypothesize that engagement will be associated with higher work interference with family due to the resources engaged employees may expend when they engage in extrarole work behavior such as organizational citizenship behaviors (OCBs) We further propose that conscientiousness, as a personal resource, serves to buffer the relationship between OCB and work interference with family Examining multisource data, collected at multiple points in time, from 3 diverse samples (total N = 844), we find that state engagement is associated with higher levels of work interference with family and that this relationship is mediated by the performance of OCBs The findings also indicate that engaged employees who are highly conscientious experience lower levels of work interference with family than engaged employees who are less conscientious The implications of our study and directions for future research are also discussed

Crystal structure of the outer membrane active transporter FepA from Escherichia coli.

Abstract: Integral outer membrane receptors for iron chelates and vitamin B12 carry out specific ligand transport against a concentration gradient. Energy for active transport is obtained from the proton-motive force of the inner membrane through physical interaction with TonB-ExbB-ExbD, an inner membrane complex. Here we report the crystal structure of an active transport, outer membrane receptor at 2.4 A resolution. Two distinct functional domains are revealed: (i) a 22-stranded beta-barrel that spans the outer membrane and contains large extracellular loops which appear to function in ligand binding; and (ii) a globular N-terminal domain that folds into the barrel pore, inhibiting access to the periplasm and contributing two additional loops for potential ligand binding. These loops could provide a signaling pathway between the processes of ligand recognition and TonB-mediated transport. The blockage of the pore suggests that the N-terminal domain must undergo a conformational rearrangement to allow ligand transport into the periplasm.
