Discursive positioning and planned change in organizations

This study uses discursive positioning theory to explore how planned change messages influence organizational members’ identity and the way they experienced organizational change. Based on an in-depth case study of a home healthcare and hospice organization that engaged in a multiyear planned change process, our analysis suggests that workers experienced salient change messages as constituting unfavorable identities, which were associated with the experiences of violation, recitation, habituation, or reservation. Our study also explores the way discursive and material contexts enabled and constrained the governing board’s change messages as they responded to external and internal audiences. We highlight the importance of viewing messaging as a process of information transfer as well as discursive construction, which has important implications for the way change agents approach issues of sense making, emotionality, resistance, and materiality during planned change processes.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Trace elements in glucometabolic disorders: an update

Many trace elements, among which metals, are indispensable for proper functioning of a myriad of biochemical reactions, more particularly as enzyme cofactors. This is particularly true for the vast set of processes involved in regulation of glucose homeostasis, being it in glucose metabolism itself or in hormonal control, especially insulin. The role and importance of trace elements such as chromium, zinc, selenium, lithium and vanadium are much less evident and subjected to chronic debate. This review updates our actual knowledge concerning these five trace elements. A careful survey of the literature shows that while theoretical postulates from some key roles of these elements had led to real hopes for therapy of insulin resistance and diabetes, the limited experience based on available data indicates that beneficial effects and use of most of them are subjected to caution, given the narrow window between safe and unsafe doses. Clear therapeutic benefit in these pathologies is presently doubtful but some data indicate that these metals may have a clinical interest in patients presenting deficiencies in individual metal levels. The same holds true for an association of some trace elements such as chromium or zinc with oral antidiabetics. However, this area is essentially unexplored in adequate clinical trials, which are worth being performed

Incremental Health Care Burden of Bleeding Among Patients with Venous Thromboembolism in the United States

BACKGROUND: The health care and economic burden of venous thromboembolism (VTE) has been evaluated in regard to acute VTE, VTE recurrence, and some VTE complications, such as postthrombotic syndrome, but the cost burden attributed to bleedings is not well understood. OBJECTIVE: To evaluate health care resource utilization and costs associated with major bleeding (MB) and clinically relevant nonmajor bleeding (CRNMB) among a large U.S. commercially and Medicare-insured population with VTE. METHODS: Patients (≥ 18 years of age, continuously insured) with a diagnosis of VTE between January 1, 2008, and December 31, 2011, were identified from the Truven Health Analytics Commercial and Medicare MarketScan databases. Patients who did not have any bleedings during the study period were grouped into a no-bleedings cohort and a random date after VTE diagnosis was selected as the index date. VTE patients who experienced MB within 1 year of the initial VTE diagnosis were grouped into a MB cohort, and patients without MB but with CRNMB were grouped into a CRNMB cohort. Baseline patient demographics and clinical characteristics were determined for study cohorts. All-cause and bleeding-related health care resource utilization and costs (inflation adjusted to 2013 level) during a 12-month follow-up period after the index date of the initial bleeding event were measured and compared. Descriptive statistics were used to evaluate differences in demographics, clinical characteristics, and unadjusted health care resource utilization and costs of patient cohorts. Multivariable generalized linear models were used to evaluate incremental health care costs of bleedings after adjusting for key patient characteristics.   RESULTS: Among the 112,885 patients identified with a VTE diagnosis, 14% (n = 15,897) had MB and 14% (n = 15,842) had CRNMB; 72% (n = 81,146) had neither of these events occur during the study period. The mean ages of the MB and CRNMB cohorts were both 63.6 years, while the mean age of the no-bleedings cohort was significantly lower at 59.6 years (P  less than  0.001). Mean Charlson Comorbidity Index scores were highest for the MB cohort (3.2), followed by those of the CRNMB cohort (2.5) and the no-bleedings cohort (1.6). The MB cohort had the greatest proportion of patients with an initial VTE event of pulmonary embolism only (23.5%), followed by that of the CRNMB cohort (20.2%), and the no-bleedings cohort (16.7%). For MB and CRNMB cohorts, the total mean bleeding-related inpatient and outpatient costs during the follow-up period were $49,779 (SE =$820) and $2,187 ($89), respectively. After adjustment for key patient characteristics, the estimated mean differences in total bleeding-related medical costs were $45,367 ($1,853) for patients with MB and $2,140 ($88) for patients with CRNMB versus patients with no bleedings. CONCLUSIONS: Among patients with VTE diagnosis in the United States, approximately 28% have a bleeding event within 1 year of VTE diagnosis, and about half of these patients experience MB. Patients with MB have greatly elevated health care costs
