E xercise testing remains a remarkably durable and versatile tool that provides valuable diagnostic and prognostic information regarding patients with cardiovascular and pulmonary disease. Exercise testing has been available for more than a half century and, like many other cardiovascular procedures, has evolved in its technology and scope. When combined with exercise testing, adjunctive imaging modalities offer greater diagnostic accuracy, additional information regarding cardiac structure and function, and additional prognostic information. Similarly, the addition of ventilatory gas exchange measurements during exercise testing provides a wide array of unique and clinically useful incremental information that heretofore has been poorly understood and underutilized by the practicing clinician. The reasons for this are many and include the requirement for additional equipment (cardiopulmonary exercise testing [CPX] systems), personnel who are proficient in the administration and interpretation of these tests, limited or absence of training of cardiovascular specialists and limited training by pulmonary specialists in this technique, and the lack of understanding of the value of CPX by practicing clinicians.Modern CPX systems allow for the analysis of gas exchange at rest, during exercise, and during recovery and yield breath-by-breath measures of oxygen uptake (V O 2 ), carbon dioxide output (V CO 2 ), and ventilation (V E). These advanced computerized systems provide both simple and complex analyses of these data that are easy to retrieve and store, which makes CPX available for widespread use. These data can be readily integrated with standard variables measured during exercise testing, including heart rate, blood pressure, work rate, electrocardiography findings, and symptoms, to provide a comprehensive assessment of exercise tolerance and exercise responses. CPX can even be performed with adjunctive imaging modalities for additional diagnostic assessment. Hence, CPX offers the clinician the ability to obtain a wealth of information beyond standard exercise electrocardiography testing that when appropriately applied and interpreted can assist in the management of complex cardiovascular and pulmonary disease.

Healthcare providers must be aware of the differences in graduate nursing roles, especially in comparing the CNS with other roles to avoid confusion that may lead to roles being underused with a limited job scope. The CNS provides a unique set of services at all system outcome levels and is an essential part of the healthcare team especially in the acute care setting.

People with diabetes are at risk of developing complications that contribute to substantial morbidity and mortality. In 2011, the American Association of Diabetes Educators convened an invitational Reducing Risks Symposium, during which an interdisciplinary panel of 11 thought leaders examined current knowledge about the reduction and prevention of diabetes-related risks and translated evidence into diabetes care and self-management education. Symposium participants reviewed findings from the literature and engaged in a moderated roundtable discussion. This report summarizes the discussion and presents recommendations to incorporate into practice to improve outcomes. The objective of the symposium was to develop practical advice for diabetes educators and other members of the diabetes care team regarding the reduction of diabetes-related risks. Optimal diabetes management requires patients to actively participate in their care, which occurs most effectively with a multidisciplinary team. Diabetes education is an integral part of this team approach because it not only helps the patient understand diabetes, its progression, and possible complications, but also provides guidance and encouragement to the patient to engage in proactive risk-reduction decisions for optimal health. A variety of tools are available to help the diabetes educator develop an individualized, patient-centered plan for risk reduction. More research is needed regarding intervention efficacy, best practices to improve adherence, and quantification of benefits from ongoing diabetes support in risk reduction. Diabetes educators are urged to stay abreast of evolving models of care and to build relationships with health care providers both within and beyond the diabetes care team.
