Permanent pacing is a risk factor for the development of heart failure.

No previous study has examined the importance of right ventricular pacing as a risk factor for the development of heart failure (HF) in subjects without a history of HF. A cohort study of patients who underwent initial pacemaker implantation (n = 11,426) was conducted to test the hypothesis that patients with ventricular dyssynchrony created by permanent pacing would develop HF, as shown by new HF hospitalizations or HF-related deaths, at a higher rate than matched controls

Long-term effect of diuretic-based therapy on fatal outcomes in subjects with isolated systolic hypertension with and without diabetes.

Diuretic-based antihypertensive therapy is associated with the development of diabetes but with improved clinical outcomes. It has been proposed that the duration of clinical trials has been too short to detect the adverse effects of diabetes. We assessed the long-term mortality rate of subjects in the Systolic Hypertension in the Elderly Program (n = 4,732) who were randomized to stepped-care therapy with 12.5 to 25.0 mg/day of chlorthalidone or matching placebo. If blood pressure remained above the goal, atenolol or matching placebo was added. At a mean follow-up of 14.3 years, cardiovascular (CV) mortality rate was significantly lower in the chlorthalidone group (19%) than in the placebo group (22%; adjusted hazard ratio [HR] 0.854, 95% confidence interval [CI] 0.751 to 0.972). Diabetes at baseline (n = 799) was associated with increased CV mortality rate (adjusted HR 1.659, 95% CI 1.413 to 1.949) and total mortality rate (adjusted HR 1.510, 95% CI 1.347 to 1.693). Diabetes that developed during the trial among subjects on placebo (n = 169) was also associated with increased CV adverse outcome (adjusted HR 1.562, 95% CI 1.117 to 2.184) and total mortality rate (adjusted HR 1.348, 95% CI 1.051 to 1.727). However, diabetes that developed among subjects during diuretic therapy (n = 258) did not have significant associations with CV mortality rate (adjusted HR 1.043, 95% CI 0.745 to 1.459) or total mortality rate (adjusted HR 1.151, 95% CI 0.925 to 1.433). Diuretic treatment in subjects who had diabetes was strongly associated with lower long-term CV mortality rate (adjusted HR 0.688, 95% CI 0.526 to 0.848) and total mortality rate (adjusted HR 0.805, 95% CI 0.680 to 0.952). Thus, chlorthalidone-based treatment improved long-term outcomes, especially among subjects who had diabetes. Subjects who had diabetes associated with chlorthalidone had no significant increase in CV events and had a better prognosis than did those who had preexisting diabetes

Toward evidence-based teaching: evaluating the effectiveness of two teaching strategies in an associate degree nursing program

The need for evidence based teaching has become an important ideology for nurse educators who are frequently encouraged to expand their teaching strategies based on recent advances in technology and student learning styles. Traditional lecture is often preferred by students, yet the literature encourages case study methodology for the development of critical thinking. A pilot study was conducted comparing learning outcomes using two different teaching strategies: lecture and case study instruction. Recommendations for using case study as a teaching methodology are offered

The “Ebb and Flow” of Documentation: Does the Transition Between Two Electronic Medical Records Systems Affect Emergency Department Efficiency?

Background: Electronic Medical Record (EMR) systems are electronic databases for compiling patient records. As healthcare networks expand, it is critical for providers to have access to patient data more broadly. As a result individual healthcare facilities must adjust to enterprise wide EMRs. Objective: This study examined the operational effects of transitioning from an Emergency Department (ED) specific EMR to an enterprise wide EMR by evaluating throughput metrics in a community ED. Methods: During a 6-month transition period (July-December 2017) in a community-based, academic ED located in North Central West Virginia, length of stay (LOS) and the following operational metrics were analyzed: door-to-provider times, door to disposition time, average LOS, left without treatment (LWOT) rates, and total ED volumes. These metrics were compared with the prior year’s same 6-month period to account for seasonal variability in patient pathology or ED volumes. Results: Overall, there was a statistically significant increase in the LOS measures, including door-to-provider time (p=0.0003), door to disposition time (p Conclusion: An ED-specific EMR to enterprise wide EMR transition in a community ED had a negative effect on the overall efficiency of the emergency department

Clarifying Definitions for the Massage Therapy Profession: the Results of the Best Practices Symposium†

Background: Massage therapists are at times unclear about the definition of massage therapy, which creates challenges for the profession. It is important to investigate the current definitions and to consider the field as a whole in order to move toward clarity on what constitutes the constructs within the profession.Purpose: To determine how a sample of experts understand and describe the field of massage therapy as a step toward clarifying definitions for massage and massage therapy, and framing the process of massage therapy practice.Setting: A two-day symposium held in 2010 with the purpose of gathering knowledge to inform and aid in the creation of massage therapy best practice guidelines for stress and low back pain.Participants: Thirty-two experts in the field of massage therapy from the United States, Europe, and Canada.Design: Qualitative analysis of secondary crosssectional data using a grounded theory approach.Results: Three over-arching themes were identified: 1) What is massage?; 2) The multidimensional nature of massage therapy; and 3) The influencing factors on massage therapy practice.Discussion: The data offered clarifying definitions for massage and massage therapy, as well as a framework for the context for massage therapy practice. These clarifications can serve as initial steps toward the ultimate goal of creating new theory for the field of massage therapy, which can then be applied in practice, education, research, and policy.Conclusions: Foundational research into how experts in the profession understand and describe the field of massage therapy is limited. Understanding the potential differences between the terms massage and massage therapy could contribute to a transformation in the profession in the areas of education, practice, research, policy and/or regulation. Additionally, framing the context for massage therapy practice invites future discussions to further clarify practice issues

Vimentin is a novel AKT1 target mediating motility and invasion.

The PI3K/AKT signaling pathway is aberrant in a wide variety of cancers. Downstream effectors of AKT are involved in survival, growth and metabolic-related pathways. In contrast, contradictory data relating to AKT effects on cell motility and invasion, crucial prometastatic processes, have been reported pointing to a potential cell type and isoform type-specific AKT-driven function. By implication, study of AKT signaling should optimally be conducted in an appropriate intracellular environment. Prognosis in soft-tissue sarcoma (STS), the aggressive malignancies of mesenchymal origin, is poor, reflecting our modest ability to control metastasis, an effort hampered by lack of insight into molecular mechanisms driving STS progression and dissemination. We examined the impact of the cancer progression-relevant AKT pathway on the mesenchymal tumor cell internal milieu. We demonstrate that AKT1 activation induces STS cell motility and invasiveness at least partially through a novel interaction with the intermediate filament vimentin (Vim). The binding of AKT (tail region) to Vim (head region) results in Vim Ser39 phosphorylation enhancing the ability of Vim to induce motility and invasion while protecting Vim from caspase-induced proteolysis. Moreover, vimentin phosphorylation was shown to enhance tumor and metastasis growth in vivo. Insights into this mesenchymal-related molecular mechanism may facilitate the development of critically lacking therapeutic options for these devastating malignancies
