Project description:BACKGROUND:Thiazolidinedione (TZD) treatment has been associated with fractures. The purpose of this study was to examine the association between TZD treatment and fractures in type 2 diabetic patients. METHODS:Using data from Translating Research into Action for Diabetes, a multicenter prospective observational study of diabetes care in managed care, we conducted a matched case-control study to assess the odds of TZD exposure in patients with type 2 diabetes with and without fractures. We identified 786 cases based on fractures detected in health plan administrative data. Up to four controls without any fracture diagnoses were matched to each case. Controls were matched on health plan, date of birth within 5 yr, sex, race/ethnicity, and body mass index within 5 kg/m(2). We performed conditional logistic regression for premenopausal and postmenopausal women and men to assess the odds of exposure to potential risk factors for fracture, including medications, self-reported limited mobility, and lower-extremity amputations. RESULTS:We found statistically significant increased odds of exposure to TZDs, glucocorticoids, loop diuretics, and self-reported limited mobility for women 50 yr of age and older with fractures. Exposure to both loop diuretics and TZDs, glucocorticoids, and insulin and limited mobility and lower-extremity amputation were associated with fractures in men. CONCLUSION:Postmenopausal women taking TZDs and the subset of men taking both loop diuretics and TZDs were at increased risk for fractures. In postmenopausal women, risk was associated with higher TZD dose. No difference between rosiglitazone and pioglitazone was apparent.

Project description:BACKGROUND:The combination of healthy lifestyle factors is associated with lower risk of coronary heart disease, diabetes, and total cardiovascular disease. Little is known about the impact of multiple lifestyle factors on the risk of stroke. METHODS AND RESULTS:We conducted a prospective cohort study among 43,685 men from the Health Professionals Follow-up Study and 71,243 women from the Nurses' Health Study. Diet and other lifestyle factors were updated from self-reported questionnaires. We defined a low-risk lifestyle as not smoking, a body mass index <25 kg/m(2), >or=30 min/d of moderate activity, modest alcohol consumption (men, 5 to 30 g/d; women, 5 to 15 g/d), and scoring within the top 40% of a healthy diet score. We documented 1559 strokes (853 ischemic, 278 hemorrhagic) among women and 994 strokes (600 ischemic, 161 hemorrhagic) among men during follow-up. Women with all 5 low-risk factors had a relative risk of 0.21 (95% confidence interval [CI], 0.12, 0.36) for total and 0.19 (95% CI, 0.09, 0.40) for ischemic stroke compared with women who had none of these factors. Among men, the relative risks were 0.31 (95% CI, 0.19, 0.53) for total and 0.20 (95% CI, 0.10, 0.42) for ischemic stroke for the same comparison. Among the women, 47% (95% CI, 18 to 69) of total and 54% (95% CI, 15 to 78%) of ischemic stroke cases were attributable to lack of adherence to a low-risk lifestyle; among the men, 35% (95% CI, 7 to 58) of total and 52% (95% CI, 19 to 75) of ischemic stroke may have been prevented. CONCLUSIONS:A low-risk lifestyle that is associated with a reduced risk of multiple chronic diseases also may be beneficial in the prevention of stroke, especially ischemic stroke.

Project description:IntroductionThere is nationwide shortage of child and adolescent behavioral health providers. Lack of diversity in the mental health care profession compounds workforce capacity issues, contributing to greater disparities in treatment access and engagement for youth from historically disenfranchised communities. Strategies are needed to foster cross-sector alignment to inform policy which can improve mental health care access and reduce disparities. This current case study details a specific research-practice-policy partnership strategy, storyboarding, as a method to engage community partners in Washington State to deliberate on information drawn from research on non-specialist models of child and adolescent mental health care to support the behavioral workforce expansion.MethodResearch evidence from a scoping literature review on non-specialist models of child and adolescent mental health care was shared via storyboards with community partners to inform policy efforts around the behavioral health workforce expansion. In Phase 1, community members with lived experience and clinical expertise contributed to the storyboard design process. In Phase 2, a broader community partner group shared their perspectives on the models of care presented in the storyboards via Qualtrics survey with open-ended questions. Listening sessions were also held with non-English speaking refugee and immigrant communities to elicit feedback on whether these models of care would meet their needs. Qualitative data was coded to explore emerging themes using a rapid deductive approach.ResultsCommunity partners shared mixed responses to models of care presented from the research literature. Immigrant and refugee communities explicitly stated these existing models would not fit their context. Regarding partnership strategy success, the smaller community partner group was engaged in the storyboard design process. The broader community interacted with and provided detailed responses to the models of care presented in the storyboards. Success was also reflected in community partners' continued participation in the next stage of the project.DiscussionFindings demonstrate how storyboarding can be effectively used to translate research evidence into accessible information to promote community partner engagement and capture community voice in policy processes. More work is needed exploring how such methods can be used to increase the use of research evidence in policy and practice spaces.

Project description:AimsRisk stratification algorithms for sudden cardiac death (SCD) in hypertrophic cardiomyopathy (HCM) and regional differences in clinical practice have evolved over time. We sought to compare primary prevention implantable cardioverter defibrillator (ICD) implantation rates and associated clinical outcomes in US vs. non-US tertiary HCM centres within the international Sarcomeric Human Cardiomyopathy Registry.Methods and resultsWe included patients with HCM enrolled from eight US sites (n = 2650) and five non-US (n = 2660) sites and used multivariable Cox-proportional hazards models to compare outcomes between sites. Primary prevention ICD implantation rates in US sites were two-fold higher than non-US sites (hazard ratio (HR) 2.27 [1.89-2.74]), including in individuals deemed at high 5-year SCD risk (≥6%) based on the HCM risk-SCD score (HR 3.27 [1.76-6.05]). US ICD recipients also had fewer traditional SCD risk factors. Among ICD recipients, rates of appropriate ICD therapy were significantly lower in US vs. non-US sites (HR 0.52 [0.28-0.97]). No significant difference was identified in the incidence of SCD/resuscitated cardiac arrest among non-recipients of ICDs in US vs. non-US sites (HR 1.21 [0.74-1.97]).ConclusionPrimary prevention ICDs are implanted more frequently in patients with HCM in US vs. non-US sites across the spectrum of SCD risk. There was a lower rate of appropriate ICD therapy in US sites, consistent with a lower-risk population, and no significant difference in SCD in US vs. non-US patients who did not receive an ICD. Further studies are needed to understand what drives malignant arrhythmias, optimize ICD allocation, and examine the impact of different ICD utilization strategies on long-term outcomes in HCM.

Project description:The Diabetes Prevention Program (DPP) lifestyle intervention reduced the incidence of type 2 diabetes mellitus (DM) among high-risk adults by 58%, with weight loss as the dominant predictor. However, it has not been adequately translated into primary care.We evaluated 2 adapted DPP lifestyle interventions among overweight or obese adults who were recruited from 1 primary care clinic and had pre-DM and/or metabolic syndrome. Participants were randomized to (1) a coach-led group intervention (n = 79), (2) a self-directed DVD intervention (n = 81), or (3) usual care (n = 81). During a 3-month intensive intervention phase, the DPP-based behavioral weight-loss curriculum was delivered by lifestyle coach-led small groups or home-based DVD. During the maintenance phase, participants in both interventions received lifestyle change coaching and support remotely-through secure email within an electronic health record system and the American Heart Association Heart360 website for weight and physical activity goal setting and self-monitoring. The primary outcome was change in body mass index (BMI) (calculated as weight in kilograms divided by height in meters squared) from baseline to 15 months.At baseline, participants had a mean (SD) age of 52.9 (10.6) years and a mean BMI of 32.0 (5.4); 47% were female; 78%, non-Hispanic white; and 17%, Asian/Pacific Islander. At month 15, the mean ± SE change in BMI from baseline was -2.2 ± 0.3 in the coach-led group vs -0.9 ± 0.3 in the usual care group (P < .001) and -1.6 ± 0.3 in the self-directed group vs usual care (P = .02). The percentages of participants who achieved the 7% DPP-based weight-loss goal were 37.0% (P = .003) and 35.9% (P = .004) in the coach-led and self-directed groups, respectively, vs 14.4% in the usual care group. Both interventions also achieved greater net improvements in waist circumference and fasting plasma glucose level.Proven effective in a primary care setting, the 2 DPP-based lifestyle interventions are readily scalable and exportable with potential for substantial clinical and public health impact.clinicaltrials.gov Identifier: NCT00842426.

Project description:Atherosclerosis is a major cause of ischemic stroke that can be effectively prevented with appropriate lifestyle modifications and control of cardiovascular risk factors. Medical advances in recent years along with aggressive cardiovascular risk factor modifications have resulted in decreased recurrence rates of atherosclerotic stroke. Non-statin lipid-lowering molecules have recently shown clinical benefit and are recommended for very high-risk patients to reduce their risk of stroke. Aggressive hypertension treatment is crucial to reduce atherosclerotic stroke risk. Advances in antithrombotic treatments include combinations of antiplatelets and new antiplatelet agents in the acute phase post-stroke, which carries a high risk of recurrence. Intensive medical treatment has also limited the indications for carotid interventions, especially for asymptomatic disease. Intracranial atherosclerotic disease may provoke stroke through various mechanisms; it is increasingly recognized as a cause of ischemic stroke with advanced imaging and is best managed with lifestyle modifications and medical therapy. The diagnostic search for the vulnerable culprit atherosclerotic plaque is an area of intense research, from the level of the intracranial arteries to that of the aortic arch. Ultrasonography and novel magnetic resonance imaging techniques (high-resolution vessel-wall imaging) may assist in the identification of vulnerable atherosclerotic plaques as the underlying cause in cryptogenic or misdiagnosed non-atherosclerotic ischemic stroke. Vertebrobasilar atherosclerotic disease is less common than carotid artery disease; thus, high-quality data on effective prevention strategies are scarcer. However, aggressive medical treatment is also the gold standard to reduce cerebrovascular disease located in posterior circulation.

Project description:Primary and secondary prevention of ischemic stroke represents a significant part of stroke management and health care. Although there are official guidelines concerning stroke management, new knowledge are introduced to them with a slight delay. This article provides an overview of current information on primary and secondary prevention of ischemic stroke. It summarizes information especially in the field of cardioembolic stroke, the use of new anticoagulants and the management of carotid stenosis based on the results of recent clinical studies. The optimal approach in stroke management is to follow these recommendations, to know new strategies and to apply an individual personalized approach in our clinical decisions.

Project description:Background and objectivesThe use of surrogate end points can decrease sample size while maintaining statistical power. This report considers incident stroke symptoms as a surrogate end point in a post hoc analysis of asymptomatic patients from the multicenter, randomized Carotid Revascularization Endarterectomy vs Stenting Trial (CREST).MethodsCREST assessed stroke symptoms using the Questionnaire for Verifying Stroke-free Status (QVSS) at baseline and follow-up. While the primary analysis of CREST defined "asymptomatic" as having been free of stroke/transient ischemic attack for 180 days, herein the population was further restricted by requiring no stroke symptoms at baseline. Incident adjudicated stroke was defined the same as for the primary analysis; incident stroke symptoms was defined as developing ≥1 stroke symptom in follow-up. Treatment differences between stenting (CAS) and endarterectomy (CEA) were assessed for 3 end points: adjudicated stroke, stroke symptoms, and adjudicated stroke or stroke symptoms.ResultsThe cohort included 826 of the 1,181 asymptomatic patients in CREST. Adjudicated stroke events occurred in 44 patients, and incident stroke symptoms occurred in 183. Analysis of adjudicated stroke end points demonstrated a nonsignificant hazard ratio (HR) for CAS compared with CEA of 1.02 (95% CI 0.57-1.85). The corresponding HR for the incident stroke symptoms outcome was 1.54 (95% CI 1.15-2.08), and the HR for the composite outcome of adjudicated stroke or incident symptoms was 1.38 (95% CI 1.04-1.83), both significant.DiscussionThe low stroke event rates in asymptomatic patients challenges the assessment of CAS-versus-CEA treatment differences. Incorporating incident stroke symptoms as a surrogate outcome increased the number of events by over 4-fold. The analysis demonstrated a previously unreported significant difference in cerebrovascular risk with CAS compared with CEA. We propose that broadening the end points of primary stroke prevention trials to include surrogate events such as incident stroke symptoms could make trials more feasible.

Project description:Two thirds of the global mortality of stroke is borne by low and middle income countries (LMICs). Pakistan is the world's sixth most populous country with a stroke-vulnerable population and is without a single dedicated chronic care center. In order to provide evidence for a viable solution responsive to this health care gap, and leveraging the existing >70% mobile phone density, we thought it rational to test the effectiveness of a mobile phone-based video intervention of short 5-minute movies to educate and support stroke survivors and their primary caregivers.Movies4Stroke will be a randomized control, outcome assessor blinded, parallel group, single center superiority trial. Participants with an acute stroke, medically stable, with mild to moderate disability and having a stable primary caregiver will be included. After obtaining informed consent the stroke survivor-caregiver dyad will be randomized. Intervention participants will have the movie program software installed in their phone, desktop, or Android device which will allow them to receive, view and repeat 5-minute videos on stroke-related topics at admission, discharge and first and third months after enrollment. The control arm will receive standard of care at an internationally accredited center with defined protocols. The primary outcome measure is medication adherence as ascertained by a locally validated Morisky Medication Adherence Scale and control of major risk factors such as blood pressure, blood sugar and blood cholesterol at 12 months post discharge. Secondary outcome measures are post-stroke complications and mortality, caregiver knowledge and change in functional outcomes after acute stroke at 1, 3, 6, 9 and 12 months. Movies4Stroke is designed to enroll 300 participant dyads after inflating 10% to incorporate attrition and non-compliance and has been powered at 95% to detect a 15% difference between intervention and usual care arm. Analysis will be done by the intention-to-treat principle.Movies4Stroke is a randomized trial testing an application aimed at supporting caregivers and stroke survivors in a LMIC with no rehabilitation or chronic support systems.NCT02202330 (28 January 2015).

Project description:The neurobiological organization of action-oriented working memory is not well understood. To elucidate the neural correlates of translating visuo-spatial stimulus sequences into delayed (memory-guided) sequential actions, we measured brain activity using functional magnetic resonance imaging while participants encoded sequences of four to seven dots appearing on fingers of a left or right schematic hand. After variable delays, sequences were to be reproduced with the corresponding fingers. Recall became less accurate with longer sequences and was initiated faster after long delays. Across both hands, encoding and recall activated bilateral prefrontal, premotor, superior and inferior parietal regions as well as the basal ganglia, whereas hand-specific activity was found (albeit to a lesser degree during encoding) in contralateral premotor, sensorimotor, and superior parietal cortex. Activation differences after long versus short delays were restricted to motor-related regions, indicating that rehearsal during long delays might have facilitated the conversion of the memorandum into concrete motor programs at recall. Furthermore, basal ganglia activity during encoding selectively predicted correct recall. Taken together, the results suggest that to-be-reproduced visuo-spatial sequences are encoded as prospective action representations (motor intentions), possibly in addition to retrospective sensory codes. Overall, our study supports and extends multi-component models of working memory, highlighting the notion that sensory input can be coded in multiple ways depending on what the memorandum is to be used for.
