    Full Text Available Stroke is an important cause for neurological morbidity and mortality. Prevention of ischemic stroke involves identification and prevention of risk factors and optimal use of pharmacotherapy. Risk factors have been classified as modifiable and non-modifiable; control of modifiable factors should prevent stroke occurrence. Stroke prevention has been described at three levels: primary, secondary and tertiary. Prolonged hypertension increases an individual′s risk for developing fatal or nonfatal stroke by three times and its control has been shown to prevent stroke. Diabetes mellitus is an important cause for microangiopathy and predisposes to stroke. Statin trials have shown significant reduction in stroke in those who were treated with statins. Stroke risk can be reduced by avoiding tobacco use, control of obesity and avoiding sedentary life style. Anti platelet medications are effective for secondary prevention of stroke. Educating society regarding modifiable risk factors and optimal use of pharmacotherapy form the cornerstone for the prevention of stroke.

    Stroke is a personal, familial, and social disaster. It is the third cause of death worldwide, the first cause of acquired disability, the second cause of dementia, and its cost is astronomic. The burden of stroke is likely to increase given the aging of the population and the growing incidence of many vascular risk factors. Prevention of stroke includes--as for all other diseases--a "mass approach" aiming at decreasing the risk at the society level and an individual approach, aiming at reducing the risk in a given subject. The mass approach is primarily based on the identification and treatment of vascular risk factors and, if possible, in the implementation of protective factors. These measures are the basis of primary prevention but most of them have now been shown to be also effective in secondary prevention. The individual approach combines a vascular risk factor modification and various treatments addressing the specific subtypes of stroke, such as antiplatelet drugs for the prevention of cerebral infarction in large and small artery diseases of the brain, carotid endarterectomy or stenting for tight carotid artery stenosis, and oral anticoagulants for the prevention of cardiac emboli. There is a growing awareness of the huge evidence-to-practice gap that exists in stroke prevention largely due to socio-economic factors. Recent approaches include low cost intervention packages to reduce blood pressure and cheap "polypills" combining in a single tablet aspirin and several drugs to lower blood pressure and cholesterol. Polypill intake should however not lead to abandon the healthy life-style measures which remain the mainstay of stroke prevention.

    Full Text Available Hypertension is the most important modifiable risk factor for primary and secondary stroke prevention.All antihypertensive drugs are effective in primary prevention: the risk reduction for stroke is 30—42%. However, not all classes of drugs have the same effects: there is some indication that angiotensin receptor blockers may be superior to other classes of antihypertensive drugs in stroke prevention.Seventy-five percent of patients who present to hospital with acute stroke have elevated blood pressure within the first 24—48 hours. Extremes of systolic blood pressure (SBP increase the risk of death or dependency. The aim of treatment should be to achieve and maintain the SBP in the range 140—160 mmHg. However, fast and drastic blood pressure lowering can have adverse consequences.The PROGRESS trial of secondary prevention with perindopril + indapamide versus placebo + placebo showed a decrease in numbers of stroke recurrences in patients given both active antihypertensive agents, more impressive for cerebral haemorrhage.There were also indications that active treatment might decrease the development of post-stroke dementia.

    Full Text Available Dževdet Smajlović Department of Neurology, University Clinical Centre Tuzla, School of Medicine, University of Tuzla, Bosnia and Herzegovina Abstract: Strokes in young adults are reported as being uncommon, comprising 10%–15% of all stroke patients. However, compared with stroke in older adults, stroke in the young has a disproportionately large economic impact by leaving victims disabled before their most productive years. Recent publications report an increased incidence of stroke in young adults. This is important given the fact that younger stroke patients have a clearly increased risk of death compared with the general population. The prevalence of standard modifiable vascular risk factors in young stroke patients is different from that in older patients. Modifiable risk factors for stroke, such as dyslipidemia, smoking, and hypertension, are highly prevalent in the young stroke population, with no significant difference in geographic, climatic, nutritional, lifestyle, or genetic diversity. The list of potential stroke etiologies among young adults is extensive. Strokes of undetermined and of other determined etiology are the most common types among young patients according to TOAST (Trial of Org 10172 in Acute Stroke Treatment criteria. Prevention is the primary treatment strategy aimed at reducing morbidity and mortality related to stroke. Therefore, primary prevention is very important with regard to stroke in young adults, and aggressive treatment of risk factors for stroke, such as hypertension, smoking, and dyslipidemia, is essential. The best form of secondary stroke prevention is directed toward stroke etiology as well as treatment of additional risk factors. However, there is a lack of specific recommendations and guidelines for stroke management in young adults. In conclusion, strokes in young adults are a major public health problem and further research, with standardized methodology, is needed in order to give us more

    Stroke is a heterogeneous syndrome, and determining risk factors and treatment depends on the specific pathogenesis of stroke. Risk factors for stroke can be categorized as modifiable and nonmodifiable. Age, sex, and race/ethnicity are nonmodifiable risk factors for both ischemic and hemorrhagic stroke, while hypertension, smoking, diet, and physical inactivity are among some of the more commonly reported modifiable risk factors. More recently described risk factors and triggers of stroke include inflammatory disorders, infection, pollution, and cardiac atrial disorders independent of atrial fibrillation. Single-gene disorders may cause rare, hereditary disorders for which stroke is a primary manifestation. Recent research also suggests that common and rare genetic polymorphisms can influence risk of more common causes of stroke, due to both other risk factors and specific stroke mechanisms, such as atrial fibrillation. Genetic factors, particularly those with environmental interactions, may be more modifiable than previously recognized. Stroke prevention has generally focused on modifiable risk factors. Lifestyle and behavioral modification, such as dietary changes or smoking cessation, not only reduces stroke risk, but also reduces the risk of other cardiovascular diseases. Other prevention strategies include identifying and treating medical conditions, such as hypertension and diabetes, that increase stroke risk. Recent research into risk factors and genetics of stroke has not only identified those at risk for stroke but also identified ways to target at-risk populations for stroke prevention. © 2017 American Heart Association, Inc.

    Full Text Available Prevention plays a crucial role in counteracting morbidity and mortality related to ischemic stroke. It has been estimated that 50% of stroke are preventable through control of modifiable risk factors and lifestyle changes. Antihypertensive treatment is recommended for both prevention of recurrent stroke and other vascular events. The use of antiplatelets and statins has been shown to reduce the risk of recurrent stroke and other vascular events. Angiotensin-converting enzyme inhibitors (ACEIs and angiotensin II receptor blockers (ARBs are indicated in stroke prevention because they also promote vascular health. Effective secondary-prevention strategies for selected patients include carotid revascularization for high-grade carotid stenosis and vitamin K antagonist treatment for atrial fibrillation. The results of recent clinical trials investigating new anticoagulants (factor Xa inhibitors and direct thrombin inhibitors clearly indicate alternative strategies in stroke prevention for patients with atrial fibrillation. This paper describes the current landscape and developments in stroke prevention with special reference to medical treatment in secondary prevention of ischemic stroke.

  12. Antithrombotic therapy for secondary stroke prevention.

    Alberts, Mark J

    2011-12-01

    : Antithrombotic therapy is a key component of any strategy for the secondary prevention of ischemic stroke. A better understanding of the various therapeutic options will lead to improved stroke prevention, better medication adherence, and fewer complications. : Antiplatelet agents and anticoagulants are the two major classes of antithrombotic therapy used for stroke prevention. The etiology and mechanism of the stroke must be considered in order to make the best decision regarding which agent(s) to use for secondary stroke prevention. The recent Prevention Regimen for Effectively Avoiding Second Strokes (PRoFESS) study showed that clopidogrel and aspirin plus extended-release dipyridamole had similar event rates in terms of recurrent stroke, but clopidogrel was better tolerated, with fewer bleeding events. Several new anticoagulants are poised to replace warfarin for stroke prevention in the setting of atrial fibrillation. These include dabigatran (a new oral direct thrombin inhibitor) and possibly apixaban (a new oral factor Xa inhibitor). These new medications are much easier to use than warfarin and may be more effective and safer, with fewer drug and food interactions and no need for routine blood monitoring. Thus, these new medications may improve adherence as well as clinicians' inclination to treat with anticoagulation. : Because each antiplatelet agent or anticoagulant has certain advantages and disadvantages, clinicians must choose an agent that the patient can afford and tolerate in terms of side effects and adherence. The hope and expectation is that the proper use of these medications in accordance with current guidelines will reduce the risk of a recurrent stroke.

    Stroke patients are at high risk for recurrence or new occurrence of other cardiovascular events or cardiovascular mortality. It is estimated that a high percentage of non-cardioembolic ischemic stroke can be prevented by a suitable modification of lifestyle (diet and exercise), reducing blood pressure (BP) with antihypertensive medication, platelet aggregation inhibitors, statins and high intake reducing consumption of. Unfortunately the degree of control of the different risk factors in secondary prevention of stroke is low. The clinical practice guidelines show clear recommendations with corresponding levels of evidence, but only if implemented in a general way they will get a better primary and secondary stroke prevention.

    Despite advances in surgical techniques and improvements in perioperative care, the incidence of perioperative strokes has not decreased, reflecting the aging of the population and the increased number of patients with complication. We investigated the cases who were consulted due to perioperative stroke. From April, 2004 to March, 2007, a total of 102 patients were referred for neurological evaluation because of perioperative stroke. Types of planned or performed surgery, risk factors, types of stroke and timing of the events were analyzed. Sixty-seven cases were consulted preoperatively for history or risk factors of stroke. Forty-seven cases had ischemic risk factors and cerebral vascular recanalization was carried out in four patients who experienced severe cerebral hypoperfusion. The other patients with ischemic risk factors were treated to avoid dehydration or hypotension perioperatively. Nine cases with hemorrhagic risk factors, such as cerebral aneurysm, were treated to avoid significant hypertension during surgery. The types of planned surgery were cardiovascular surgery in 29 cases, abdominal surgery in 13, cervical surgery in 7, and thoracic surgery in 6. Except for one case, who suffered cerebral embolism due to cardiac surgery, those who were consulted preoperatively did not experience stroke. Neurological events had occurred in 35 patients and they were consulted postoperatively. The surgical procedures were cardiovascular surgery in 19 patients, thoracic surgery in 6, abdominal surgery in 6. The types of stroke were cerebral infarction in 20 cases, hypoxic brain in 8, and transient ischemic attack in 5. The cause of the cerebral infarction was considered as cerebral embolism in 19 cases. Those who were consulted preoperatively were treated to prevent intraoperative stroke and did not suffer neurological complication. Most stoke in patients undergoing surgery were not related to hypoperfusion but due to embolism.

    Full Text Available Cardiovascular disease is the leading cause of death and disability, and contributes substantially to healthcare budgets. The lipid-lowering drugs, 3-hydroxy-3-methylgulutaryl-coenzyme A (HMG-CoA reductase inhibitor or statins, reducing mortality and cardiovascular morbidity in patients with established cardiovascular disease. Statins therefore have a place in the secondary prevention of cardiovascular disease. Recent experimental and clinical studies suggest that statins may exert vascular protective effect beyond cholesterol reduction. The cholesterol-independet or “pleiotropic” effects of statin include the upregulation and activation of endothelial nitric acid synthase (eNOS that can increase nitric oxide (NO production. Augmentation of NO production increases cerebral blood flow, which can lead to neuroprotection during brain ischaemia. By inhibiting mevalonate synthesis, statins prevent the formation of several isoprenoids (including farnesylpyrophosphate and geranylgeranylpyrophosphate. Inhibiting geranylgeranylation of RhoA small G proteins increases the stability of eNOS mRNA through the remodeling of endothelial actin microfilamens. Moreover, statins directly increase eNOS activity within minutes by activating the pathway involving phosphoinositide 3-kinase and protein kinase B. In the secondary prevention of stroke, the use of statins reduces the incidence of either recurrent stroke or other major vascular events and treatment should be initiated soon after the event. The use of statins does not increase hemorrhagic stroke or cancer and may also favor atherosclerotic plaque regression.

  1. Preventing Heart Attacks and Strokes: Increasing Awareness ...

    Science.gov (United States)

    Summary: Chronic cardiovascular disease imposes a significant health and economic burden on individuals and communities. Despite decades of improvement in cardiovascular mortality, cardiovascular disease and stroke remain the leading cause of death in the U.S. and disparities in health outcomes persist. Moreover, the continuous improvement in cardiovascular mortality typical of the last four decades has ended motivating new and innovative approaches to improve population health and wellbeing. Apart from continued focus on traditional risk factor modification such as identification and treatment of high blood pressure and cholesterol, cessation of smoking, and appropriate use of evidence-based pharmacological prevention measures and disease management, other factors should be considered such as increasing physical activity, dietary sodium reduction and modification of social and environmental determinants known to cause heart attacks and stroke and exacerbate vascular disease. Such an approach will require greater cooperation among public health, environmental health, the broader public and private healthcare delivery and payment systems, and federal agencies. To introduce this concept the U.S. EPA held a workshop in September 2016 bringing together representatives of local and state public health officials, the healthcare system, educators, data analytics, and federal partners (CMS, CDC, Dept. of State and EPA) for the purpose of exploring the idea of prom

    Thiazides have been used for the control of blood pressure and primary prevention of ischemic stroke. No previous studies have assessed the influence of thiazides on functional prognosis after ischemic stroke. Demographics, prestroke conditions, poststroke National Institutes of Health Stroke Scale score, and clinical and laboratory parameters were prospectively registered in 216 Taiwanese patients. One hundred forty patients who completed follow-up 3 months after experiencing ischemic stroke were assessed with the modified Rankin scale as functional prognoses. Twenty-one patients used thiazide to control hypertension before experiencing ischemic stroke. No differences of stroke subtypes and comorbidities before stroke were observed between the 2 groups. The emergency department National Institutes of Health Stroke Scale was lesser among thiazide users (4 [2-7] versus 6 [4-16], P = .02). Among 140 patients who completed follow-up in 90 days, thiazide users had more favorable functional status (modified Rankin scale ≤2: 42.4% versus 26.9%, P = .02, odds ratio 3.34, 95%, confidence interval .130-.862). Hypertensive patients treated with thiazides long term had a lesser severity of stroke and better functional outcomes after ischemic stroke. Copyright © 2014 National Stroke Association.

    2014-01-01

    Perceptions that stress causes and stress-reduction controls hypertension have been associated with poorer blood pressure (BP) control in hypertension populations. The current study investigated these "stress-model perceptions" in stroke survivors regarding prevention of recurrent stroke and the influence of these perceptions on patients' stroke risk factor control. Stroke and transient ischemic attack survivors (N=600) participated in an in-person interview in which they were asked about their beliefs regarding control of future stroke; BP and cholesterol were measured directly after the interview. Counter to expectations, patients who endorsed a "stress-model" but not a "medication-model" of stroke prevention were in better control of their stroke risk factors (BP and cholesterol) than those who endorsed a medication-model but not a stress-model of stroke prevention (OR for poor control=.54, Wald statistic=6.07, p=.01). This result was not explained by between group differences in patients' reported medication adherence. The results have implications for theory and practice, regarding the role of stress belief models and acute cardiac events, compared to chronic hypertension.

    Full Text Available Despite vitamin K antagonists (VKAs are considered the first choice treatment for stroke prevention in atrial fibrillation (AF, literature shows their underuse in this context. Since data about VKAs use prior and after acute stroke lack, the aim of this study was to focus on management of anticoagulation with VKAs in this context. Data were retrieved from Tuscan FADOI Stroke Registry, an online data bank aimed to report on characteristics of stroke patients consecutively admitted in Internal Medicine wards in 2010 and 2011. In this period 819 patients with mean age 76.5±12.3 years were enrolled. Data on etiology were available for 715 of them (88.1%, 87% being ischemic and 13% hemorrhagic strokes. AF was present in 238 patients (33%, 165 (69.3% having a known AF before hospitalization, whereas 73 patients (31.7% received a new diagnosis of AF. A percentage of 89% of strokes in patients with known AF were ischemic and 11% hemorrhagic. A percentage of 86.7% of patients with known AF had a CHADS2 ≥2, but only 28.3% were on VKAs before hospitalization. A percentage of 78.8% of patients treated with VKAs before stroke had an international normalized ratio (INR ≤2.0; 68.7% of patients with VKAs-related hemorrhagic strokes had INR ≤3.0. Combined endpoint mortality or severe disability in patients with ischemic stroke associated with AF was present in 47%, while it was present in 19.30% and 19.20% of atherothrombotic and lacunar strokes, respectively. At hospital discharge, VKAs were prescribed in 25.9% of AF related ischemic stroke patients. AF related strokes are burdened by severe outcome but VKAs are dramatically underused in patients with AF, even in higher risk patients. Efforts to improve anticoagulation in this stroke subtype are warranted.

    Full Text Available Non-adherence to stroke prevention medications is a risk factor for first-ever and recurrent stroke. As of yet, there are no guidelines for processes to recognize and address medication non-adherence in stroke patients. We developed a new model of post-discharge prevention care that measures and addresses medication-taking (TRAnsition Coaching for Stroke or TRACS. TRACS includes personalized education about risk factors and medications prior to discharge, follow-up telephone calls, and appointments with a stroke nurse practitioner (NP. The stroke NP asks about medication use (persistence and whether doses are missed (adherence, and helps to solve problems with access to medications or side effects. In an analysis of 142 patients enrolled in TRACS from October 2012 to February 2014, medication persistence (use of medications from discharge to the time of measurement was about 80%. Medication persistence at NP visit was higher in those patients with a first-ever stroke (78.9 % vs those with recurrent stroke (60.7 %; p=0.045. Concerted efforts with 2-day RN follow-up calls and earlier NP appointments to improve medication-taking behaviors are underway.

    BACKGROUND: In patients with ischemic stroke of non-cardioembolic origin, acetylsalicylic acid, clopidogrel, or a combination of acetylsalicylic acid and dipyridamole are recommended for the prevention of a recurrent stroke. The purpose of this study was to examine the risk of bleeding or recurrent...... were calculated for each antiplatelet regimen. RESULTS: Among patients discharged after first-time ischemic stroke, 3043 patients were treated with acetylsalicylic acid, 12,295 with a combination of acetylsalicylic acid and dipyridamole, and 3885 with clopidogrel. Adjusted HRs for clopidogrel versus...... the combination of acetylsalicylic acid and dipyridamole were 1.02 (95% confidence interval [CI]: 0.89-1.17) for ischemic stroke and 1.06 (95% CI: 0.83-1.35) for bleeding. Adjusted HRs for acetylsalicylic acid versus the combination of acetylsalicylic acid and dipyridamole were 1.48 (95% CI: 1.31-1.67) for stroke...

    2017-01-01

    Full Text Available Polyphenols have an important protective role against a number of diseases, such as atherosclerosis, brain dysfunction, stroke, cardiovascular diseases, and cancer. Cardiovascular diseases are the number one cause of death worldwide: more people die annually from cardiovascular diseases than from any other cause. The most important behavioural risk factors of heart disease and stroke are unhealthy diet, physical inactivity, tobacco use, and excess alcohol intake. The dietary consumption of polyphenols has shown to be inversely associated with morbidity and mortality by cardio- and cerebrovascular diseases. It is well-known that the protective effects of polyphenols in vivo depend on the grade how they are extracted from food and on their intestinal absorption, metabolism, and biological action with target tissues. The aim of this review was to summarise the relation between polyphenols of different plant sources and stroke in human intervention studies, animal models, and in vitro studies.

    Full Text Available The paper reviews the data available in the literature on the prevention of stroke in atrial fibrillation (AF. Until recently, mainly warfarin was noted to be used to prevent stroke in AF, which required regulatory laboratory (hematological control. The authors give the results of the RE-LY trial that compared the efficacy of the new thrombin inhibitor dabigatran (pradax in a dose of 150 or 110 mg twice daily and warfarin. The trial has indicated that the use of dabigatran in a dose of 150 mg twice daily results in a reduction in the rate of stroke and systemic embolism as compared to that with warfarin treatment. The administration of dabigatran in a dose of 150 or 110 mg twice daily decreases the rate of deaths from all cases, life-threatening hemorrhages, and hemorrhagic stroke as compared to that of warfarin. The prospects for using different doses of dabigatran in AF patients with prior ischemic stroke (IS or transient ischemic attack (TIA are discussed. In our country, most patients with prior IS or TIA in the presence of AF do not take warfarin due to the difficulty of regulatory laboratory control, the introduction of dabigatran into neurological care may increase the number of patients receiving effective anticoagulant therapy to prevent re-stroke.

    Prior studies indicate that young African-Americans (AA) have a greater frequency of ischemic stroke than similarly aged European-Americans (EA). We hypothesized that differences in stroke subtype frequency mediated through sex and differing risk factor profiles may play a role in ethnicity-specific stroke. Utilizing our biracial young-onset stroke population, we explored these relationships. Fifty nine hospitals in the Baltimore-Washington area participated in a population-based study of young-onset stroke in men (218-AA, 291-EA) and women (219-AA, 222-EA) aged 16-49. Data on age, sex, ethnicity and stroke risk factors (hypertension (HTN) and smoking) were gathered through standardized interview. A pair of vascular neurologists adjudicated each case to determine TOAST subtype. Logistic regression analyses evaluating for differences in stroke risk factors by TOAST subtype were performed. Analyses controlling for age and sex demonstrated that AA were more likely to have a lacunar stroke than EA (OR = 1.61; 95% CI = 1.12-2.32; p = 0.011) when utilizing the other TOAST subtypes as the reference group. This effect was mediated by HTN, which increases the risk of lacunar stroke (OR = 2.03; 95% CI = 1.38-2.98; p = 0.0003) and large artery stroke (OR = 1.70; 95% CI = 1.01-2.88; p = 0.048) when controlling for sex, ethnicity, and age. Cases below age 40 were more likely to have a cardioembolic stroke than those above age 40 (OR = 1.62; 95% CI = 1.15-2.27; p = 0.006), controlling for sex and ethnicity. Lastly, current smokers were more likely to have a large artery stroke than non-smokers (OR = 1.79; 95% CI = 1.08-2.98; p = 0.024). Our population-based data demonstrate ethnic differences in ischemic stroke subtypes. These findings may help clarify mechanisms of stroke in young adults which may in part be driven by ethnic-specific differences in early-onset traditional risk factors, thereby indicating differing emphasis on workup and prevention.

  1. Stroke Prevention in Atrial Fibrillation: Focus on Latin America

    Science.gov (United States)

    Massaro, Ayrton R.; Lippp, Gregory Y. H.

    2016-01-01

    Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, with an estimated prevalence of 1-2% in North America and Europe. The increased prevalence of AF in Latin America is associated with an ageing general population, along with poor control of key risk factors, including hypertension. As a result, stroke prevalence and associated mortality have increased dramatically in the region. Therefore, the need for effective anticoagulation strategies in Latin America is clear. The aim of this review is to provide a contemporary overview of anticoagulants for stroke prevention. The use of vitamin K antagonists (VKAs, eg, warfarin) and aspirin in the prevention of stroke in patients with AF in Latin America remains common, although around one fifth of all AF patients receive no anticoagulation. Warfarin use is complicated by a lack of access to effective monitoring services coupled with an unpredictable pharmacokinetic profile. The overuse of aspirin is associated with significant bleeding risks and reduced efficacy for stroke prevention in this patient group. The non-VKA oral anticoagulants (NOACbs) represent a potential means of overcoming many limitations associated with VKA and aspirin use, including a reduction in the need for monitoring and a reduced risk of hemorrhagic events. The ultimate decision of which anticoagulant drug to utilize in AF patients depends on a multitude of factors. More research is needed to appreciate the impact of these factors in the Latin American population and thereby reduce the burden of AF-associated stroke in this region. PMID:28558081

    Full Text Available Atrial fibrillation is associated with a few folds higher risk of stroke. Traditional vitamin K antagonists used in the prevention of stroke in patients with non-valvular atrial fibrillation are often not efficient enough due to their interactions with a broad range of substances including medicines or food ingridients and problems with monitoring the treatment. New oral anticoagulants pose an alternative for the vitamin K antagonists. They are equally efficient in the prevention of stroke, but are safer and have no requirement for routine coagulation monitoring. We present a case of a patient with atrial fibrillation, high risk of tromboembolism and recurring episodes of hemorrhages. Considering the possible complications, rivaroxaban was administered.

    Full Text Available AbstractBackground: There are significant racial disparities in stroke incidence and mortality. Health fairs and outreach programs can be used to increase stroke literacy, but they often fail to reach those at highest risk, including African American males. Methods: We conducted a stroke outreach and screening program at an inner city market in order to attract a high-risk group for a stroke education intervention. A modified Framingham risk tool was used to estimate stroke risk and a 10-item quiz was developed to assess stroke literacy among 80 participants. We report results of the demographic and stroke risk analyses and stroke knowledge assessment. Results: The program attracted a majority male (70% and African American (95% group of participants. Self-reported hypertension (57.5%, tobacco use (40%, and diabetes (23.8% were prevalent. Knowledge of stroke warning signs, risk factors, and appropriate action to take for stroke symptoms was not poor when compared to the literature. Conclusions: Stroke outreach and screening in an inner city public market may be an effective way to target a high-risk population for stroke prevention interventions. Stroke risk among participants was high despite adequate stroke knowledge.

    Despite long-standing and worldwide efforts, hemorrhagic stroke remains a critical clinical syndrome that exerts a heavy toll on affected individuals and their families due to the lack of preventive and therapeutic targets. To clarify the pathogenesis of hemorrhagic stroke and to identify novel therapeutic targets. Targeting pericytes, the typical mural cells of microvessels, could serve as a way to modulate microvascular permeability, development, and maturation by regulating endothelial cell functions and modulating tissue fibrosis and inflammatory responses. Pericytes in hemorrhagic stroke may exert the following functions: before bleeding, the morphological aberration and dysfunction of pericytes may lead to aneurysm formation, angiopsathyrosis, and hemodynamic disturbances, ultimately causing vasculature rupture. In the acute phase after hemorrhage, pericytes are faced with a complicated bleeding environment, which results in the death of pericytes, blood-brain barrier damage, pericyte-mediated inflammatory cascades, white matter impairment, and ultimately aggravated neural injury. In the recovery period post-hemorrhage, in situ pericytes are activated and differentiate into neurons, glia and endothelial cells to repair the neural vascular network. Moreover, many pericytes are recruited to the lesion and contribute to blood-brain barrier remodeling, thus facilitating neurovascular functional recovery after stroke. Due to the multiple functions of pericytes in the development of vascular rupture and hemorrhagic stroke pathophysiology, additional drugs and trials targeting pericytes and evaluations of their effectiveness are required in future investigations to develop new strategies for the prevention and treatment of hemorrhagic stroke.

  10. B vitamins in stroke prevention: time to reconsider.

    Science.gov (United States)

    Spence, J David; Yi, Qilong; Hankey, Graeme J

    2017-09-01

    B vitamin therapy lowers plasma total homocysteine concentrations, and might be a beneficial intervention for stroke prevention; however, cyanocobalamin (a form of vitamin B12) can accelerate decline in renal function and increase the risk of cardiovascular events in patients with impaired renal function. Although early trials did not show benefit in reduction of stroke, these results might have been due to harm in participants with impaired renal function. In patients with diabetic nephropathy, cyanocobalamin is harmful, whereas B vitamins appear to reduce cardiovascular events in study participants with normal renal function. Our meta-analysis of individual patient data from two large trials of B vitamin therapy (VISP and VITATOPS) indicates that patients with impaired renal function who are exposed to high-dose cyanocobalamin do not benefit from therapy with B vitamins for the prevention of stroke (risk ratio 1·04, 95% CI 0·84-1·27), however, patients with normal renal function who are not exposed to high-dose cyanocobalamin benefit significantly from this treatment (0.78, 0·67-0·90; interaction p=0·03). The potential benefits of B vitamin therapy with folic acid and methylcobalamin or hydroxycobalamin, instead of cyanocobalamin, to lower homocysteine concentrations in people at high risk of stroke warrant further investigation.

  11. Drug treatments in the secondary prevention of ischaemic stroke.

    Science.gov (United States)

    Schulz, Ursula G

    2013-11-01

    Stroke is an important cause of death and disability. However, about two thirds of cerebrovascular events are initially minor. They carry a high risk of potentially severe recurrent events, but they also offer an opportunity for secondary prevention to avoid such recurrences. As most recurrent events occur within a short time after the initial presentation, secondary prevention has to be started as soon as possible. Dramatic risk reduction can be achieved with well-established drugs if used in a timely manner. A standard secondary preventive regimen will address multiple vascular risk factors and will usually consist of an antiplatelet agent, a lipid lowering drug, and an antihypertensive agent. Depending on the risk factor profile of each patient, this will have to be adjusted individually, for example, taking into account the presence of cardioembolism or of stenotic disease of the brain-supplying arteries. In recent years, the approach to treating these risk factors has evolved. In addition to absolute blood pressure, blood pressure variability has emerged as an important contributing factor to stroke risk, which is affected differently by different antihypertensive agents. New oral anticoagulants reduce the risk of cerebral haemorrhage and the need for regular blood checks. The best antiplatelet regimen for stroke prevention is still uncertain, and treatment of dyslipidaemia may change if trials with cholesteryl ester transfer protein (CETP) inhibitors, which increase levels of HDL-cholesterol, are successful. This article reviews the current evidence for drug treatments in the secondary prevention of ischaemic stroke. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    2017-01-01

    Abstract Background: This review aims to summarize the evidence of Tai Chi and qigong interventions for the primary prevention of stroke, including the effects on populations with major stroke risk factors. Methods: A systematic literature search was conducted on January 16, 2017 using the PubMed, Scopus, Cochrane Library, and CINAHL databases. Randomized controlled trials examining the efficacy of Tai Chi or qigong for stroke prevention and stroke risk factors were included. Risk of bias was assessed using the Cochrane Risk of Bias tool. Results: Twenty-one trials with n = 1604 patients with hypertension, hyperlipidaemia, diabetes, overweight or obesity, or metabolic syndrome were included. No trials were found that examined the effects of Tai Chi/qigong on stroke incidence. Meta-analyses revealed significant, but not robust, benefits of Tai Chi/qigong over no interventions for hypertension (systolic blood pressure: −15.55 mm Hg (95% CI: −21.16; −9.95); diastolic blood pressure: −10.66 mm Hg (95% CI: −14.90, −6.43); the homeostatic model assessment (HOMA) index (−2.86%; 95% CI: −5.35, −0.38) and fasting blood glucose (−9.6 mg/dL; 95% CI: −17.28, −1.91), and for the body mass index compared with exercise controls (−1.65 kg/m2; 95% CI: −3.11, −0.20). Risk of bias was unclear or high for the majority of trials and domains, and heterogeneity between trials was high. Only 6 trials adequately reported safety. No recommendation for the use of Tai Chi/qigong for the prevention of stroke can be given. Conclusion: Although Tai Chi and qigong show some potential more robust studies are required to provide conclusive evidence on the efficacy and safety of Tai Chi and qigong for reducing major stroke risk factors.

    (1) To demonstrate the importance of nutrition, especially sodium restriction and increased potassium and protein intakes, in the prevention of hypertension and stroke in a pilot study involving senior citizens. (2) To design a population-based intervention in the Shimane Prefecture of Japan concerning dietary factors such as low sodium and high potassium, protein, magnesium, calcium and dietary fibre in the prevention of stroke. The intervention study was carried out at a senior citizens' residence and included general health education along with a reduction of dietary salt intake and increases in vegetable and protein, especially from seafood. Sixty-three healthy senior citizens (average age: 74.8 +/- 7.7 years) had their daily meals modified to a low sodium/potassium ratio for four weeks without their knowledge by the use of a potassium chloride substitute for salt, soy sauce and bean paste, which contains much less sodium and more potassium. Monosodium L-glutamate monohydrate used for cooking was changed to monopotassium L-glutamate monohydrate. Blood pressure was measured with the patient in the sitting position. Daily dietary sodium and potassium intakes were assessed by flame photometry from 24-hour urine specimens. Extensive intervention programs were introduced into the Shimane Prefecture, which has a population of 750,000, through health education classes for housewives, home visits by health nurses and an educational TV program for dietary improvement. The mortality from stroke was monitored for 10 years and compared with the average in Japan. The blood pressure lowering effect of reducing the dietary sodium/potassium ratio was confirmed through a pilot intervention study at the senior citizens' residence. The mortality rates for stroke in the middle-aged population from the Shimane Prefecture during the 10 years after the introduction of dietary improvement had a steeper decline in hemorrhagic, ischemic and all strokes than the average for Japan.

    The effect of aspirin in primary prevention of stroke is controversial among clinical trials conducted in Western countries, and no data are available for Asian populations with a high risk of intracranial hemorrhage. The objective of this study was to evaluate the effect of aspirin on the risk of stroke and intracranial hemorrhage in the Japanese Primary Prevention Project (JPPP). A total of 14 464 patients (age, 60-85 years) with hypertension, dyslipidemia, and diabetes mellitus participated and were randomized into 2 treatment groups: 100 mg of aspirin or no aspirin. The median follow-up period was 5.02 years. The cumulative rate of fatal or nonfatal stroke was similar for the aspirin (2.068%; 95% confidence interval [CI], 1.750-2.443) and no aspirin (2.299%; 95% CI, 1.963-2.692) groups at 5 years; the estimated hazard ratio was 0.927 (95% CI, 0.741-1.160; P=0.509). Aspirin nonsignificantly reduced the risk of ischemic stroke or transient ischemic attack (hazard ratio, 0.783; 95% CI, 0.606-1.012; P=0.061) and nonsignificantly increased the risk of intracranial hemorrhage (hazard ratio, 1.463; 95% CI; 0.956-2.237; P=0.078). A Cox regression adjusted by the risk factors for all stroke, which were age >70 years, smoking, and diabetes mellitus, supported the above result. Aspirin did not show any net benefit for the primary prevention of stroke in elderly Japanese patients with risk factors for stroke, whereas age >70 years, smoking, and diabetes mellitus were risk factors for stroke regardless of aspirin treatment.

RESULTS: Over 4.9 years, strokes occurred in 576 subjects. There were reductions in fatal, severe (modified Rankin Scale score 5...

  16. Antiplatelet agents in secondary prevention of stroke: a perspective.

    Science.gov (United States)

    2005-09-01

    Antiplatelet agents are widely used in the secondary prevention of stroke and other vascular events. The purpose of this review is to give a perspective of the factors involved in clinical practice for selecting antiplatelet drugs appropriate to the patient population. Aspirin remains the most popular drug, because it is modestly effective (approximately 25% risk reduction); however, it has undesirable side effects that are sometimes serious. The nonaspirin compounds are marginally more effective but are much more expensive and subject to commercial pressures from industry. A completely new look at these compounds is necessary, rather than spending more precious resources on "drug wars" that are expensive in time and money. A "polypill" has been previously proposed, and possibly a combination of drugs targeted at the major vascular risk factors that is given to patients within 24 hours of initial stroke symptoms and to clearly defined patient populations may prove a solution.

    2013-01-01

    Full Text Available Extra cranial carotid artery stenosis is an important cause of stroke, which often needs treatment with carotid revascularization. To prevent stroke recurrence, carotid endarterectomy (CEA has been well-established for several decades for symptomatic high and moderate grade stenosis. Carotid stenting is a less invasive alternative to CEA and several recent trials have compared the efficacy of the 2 procedures in patients with carotid stenosis. Carotid artery stenting has emerged as a potential mode of therapy for high surgical risk patients with symptomatic high-grade stenosis. This review focuses on the current data available that will enable the clinician to decide optimal treatment strategies for patients with carotid stenosis.

    Stroke is the main cause of disability in high-income countries and ranks second as a cause of death worldwide. Infections occur frequently after stroke and may adversely affect outcome. Preventive antibiotic therapy in the acute phase of stroke may reduce the incidence of infections and improve outcome. In the previous version of this Cochrane Review, published in 2012, we found that antibiotics did reduce the risk of infection but did not reduce the number of dependent or deceased patients. However, included studies were small and heterogeneous. In 2015, two large clinical trials were published, warranting an update of this Review. To assess the effectiveness and safety of preventive antibiotic therapy in people with ischaemic or haemorrhagic stroke. We wished to determine whether preventive antibiotic therapy in people with acute stroke:• reduces the risk of a poor functional outcome (dependency and/or death) at follow-up;• reduces the occurrence of infections in the acute phase of stroke;• reduces the occurrence of elevated body temperature (temperature ≥ 38° C) in the acute phase of stroke;• reduces length of hospital stay; or• leads to an increased rate of serious adverse events, such as anaphylactic shock, skin rash, or colonisation with antibiotic-resistant micro-organisms. We searched the Cochrane Stroke Group Trials Register (25 June 2017); the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 5; 25 June 2017) in the Cochrane Library; MEDLINE Ovid (1950 to 11 May 2017), and Embase Ovid (1980 to 11 May 2017). In an effort to identify further published, unpublished, and ongoing trials, we searched trials and research registers, scanned reference lists, and contacted trial authors, colleagues, and researchers in the field. Randomised controlled trials (RCTs) of preventive antibiotic therapy versus control (placebo or open control) in people with acute ischaemic or haemorrhagic stroke. Two review authors independently selected

    Full Text Available Although stroke incidence in high-income countries (HICs decreased over the past four decades, it increased dramatically in low- and middle-income countries (LMICs. In this review, we describe the current status of primary prevention, treatment, and management of acute stroke and secondary prevention of and rehabilitation after stroke in LMICs. Although surveillance, screening, and accurate diagnosis are important for stroke prevention, LMICs face challenges in these areas due to lack of resources, awareness, and technical capacity. Maintaining a healthy lifestyle, such as no tobacco use, healthful diet, and physical activity are important strategies for both primary and secondary prevention of stroke. Controlling high blood pressure is also critically important in the general population and in the acute stage of hemorrhagic stroke. Additional primary prevention strategies include community-based education programs, polypill, prevention and management of atrial fibrillation, and digital health technology. For treatment of stroke during the acute stage, specific surgical procedures and medications are recommended, and inpatient stroke care units have been proven to provide high quality care. Patients with a chronic condition like stroke may require lifelong pharmaceutical treatment, lifestyle maintenance and self-management skills, and caregiver and family support, in order to achieve optimal health outcomes. Rehabilitation improves physical, speech, and cognitive functioning of disabled stroke patients. It is expected that home- or community-based services and tele-rehabilitation may hold special promise for stroke patients in LMICs.

    Full Text Available Sickle Cell Disease(SCD is one of the most common hemoglobinopathies in the world which causes stroke. The management of stroke depends on the manifestations and the age of the patient. Especially in childhood, anatomic and physiological abnormalities of CNS may be a predisposing factors. Stroke mostly affects the distal segments of the Internal Carotid Artery, but also middle and anterior segments of the cerebral arteries are involved. The most important predisposing factors are the arterial malformations, stenosis and obstructions in cranial arteries, generally involving Internal Carotid Artery, frequently Proximal Middle Cerebral or Anterior Cerebral Arteries. After infarcts at brain vessels, most frequent clinical findings are hemiparesis or hemiplegia, impaired speech, focal seizures, gait disturbances. Risk factors for predisposing stroke are prior transient ischemia, baseline Hb decrease, acute chest sydrome within previous two weeks, systolic blood pressure rises, leucocyte increases. The patient with silent stroke or transient ischemic attacks may be asymptomatic or without neurological symptoms. Neuroimaging abnormalities may be seen without significant clinical findings in children with SCD. We talk about silent stroke if there are neuroradiological abnormalities without clinical findings. Children with silent strokes are more prone to new strokes. If there is a significant stroke a ischemic stroke often present with focal neurological signs and symptoms. If patient is asymptomatic or have suspected stroke, first step may be performance of Transcranial Doppler Ultrasonography (TCD. Children with time-averaged mean velocity (TAMV, measured in Middle Carotid Artery or in distal internal carotid Artery abnormally elevated, defined as TAMV≥200cm/sec, have sixfold increase for stroke than those with normal TAMV≤170cm/sec. For these patients under the risk of stroke, chronic blood transfusion is recommended for prevention of primary

    2016-01-01

    The Preventive Antibiotics in Stroke Study (PASS), a randomized open-label masked endpoint trial, showed that preventive ceftriaxone did not improve functional outcome at 3 months in patients with acute stroke (adjusted common OR 0.95; 95% CI 0.82-1.09). Post-hoc analyses showed that among patients who received intravenous thrombolysis (IVT), patients who received ceftriaxone had a significantly better outcome as compared with the control group. This study aimed to gain more insight into the characteristics of these patients. In PASS, 2,550 patients were randomly assigned to preventive antibiotic treatment with ceftriaxone or standard care. In current post-hoc analysis, 836 patients who received IVT were included. Primary outcome included functional status on the modified Rankin Scale, analyzed with adjusted ordinal regression. Secondary outcomes included infection rate and symptomatic intracerebral hemorrhage (sICH) rate. For all patients in PASS, the p value for the interaction between IVT and preventive ceftriaxone regarding functional outcome was 0.03. Of the 836 IVT-treated patients, 437 were administered ceftriaxone and 399 were allocated to the control group. Baseline characteristics were similar. In the IVT subgroup, preventive ceftriaxone was associated with a significant reduction in unfavorable outcome (adjusted common OR 0.77; 95% CI 0.61-0.99; p = 0.04). Mortality at 3 months was similar (OR 0.75; 95% CI 0.48-1.18). Preventive ceftriaxone was associated with a reduction in infections (OR 0.43; 95% CI 0.28-0.66), and a trend towards an increased risk for sICH (OR 3.09; 95% CI 0.85-11.31). Timing of ceftriaxone administration did not influence the outcome (aOR 1.00; 95% CI 0.98-1.03; p = 0.85). According to the post-hoc analysis of PASS, preventive ceftriaxone may improve the functional outcome in IVT-treated patients with acute stroke, despite a trend towards an increased rate of post-IVT-sICH. © 2016 S.

  4. Risk factors and strategies for stroke prevention in low to middle-income countries

    Directory of Open Access Journals (Sweden)

    В. Л. Фейгин

    2015-10-01

    Full Text Available A recent meta-analysis of the population-based stroke incidence studies showed a significant trend towards almost 2-fold increasing of stroke incidence rates in low to middle-income countries over the last 4 decades. The study also demonstrated that stroke incidence rates in low to middle-income countries currently exceed the level of stroke incidence in the developed (high income countries by 20%. Compared with people in high-income countries, people in low to middle-income countries also experience a higher stroke mortality rate and greater proportions of hemorrhagic strokes. Should the current trends in stroke incidence and aging of the population continue, deaths from stroke in the developing countries will increase over the next decade by 20% and the overall burden of stroke may soon become unbearable for the economy of these countries. The way to stop the stroke pandemic and reduce stroke incidence is effective stroke prevention. In this review, we summarize current evidence for stroke risk factors and prevention in low to middle-income countries and outline possible promising strategies for tackling the problem.

    To gain better understanding of (i) beliefs and knowledge about stroke; (ii) attitudes about walking for stroke prevention; and (iii) barriers and facilitators to walking among Korean seniors for the cultural tailoring of a stroke prevention walking programme. Physical inactivity is a major risk factor for stroke. Korean immigrant seniors are one of the most sedentary ethnic groups in the United States. An explorative study using focus group data. Twenty-nine Korean immigrant seniors (64-90 years of age) who had been told by a doctor at least once that their blood pressure was elevated participated in 3 focus groups. Each focus group consisted of 8-11 participants. Focus group audiotapes were transcribed and analysed using standard content analysis methods. Participants identified physical and psychological imbalances (e.g. too much work and stress) as the primary causes of stroke. Restoring 'balance' was identified as a powerful means of stroke prevention. A subset of participants expressed that prevention may be beyond human control. Overall, participants acknowledged the importance of walking for stroke prevention, but described barriers such as lack of personal motivation and unsafe environment. Many participants believed that providing opportunities for socialisation while walking and combining walking with health information sessions would facilitate participation in and maintenance of a walking programme. Korean immigrant seniors believe strongly that imbalance is a primary cause of stroke. Restoring balance as a way to prevent stroke is culturally special among Koreans and provides a conceptual base in culturally tailoring our stroke prevention walking intervention for Korean immigrant seniors. A stroke prevention walking programme for Korean immigrant seniors may have greater impact by addressing beliefs about stroke causes and prevention such as physical and psychological imbalances and the importance of maintaining emotional well-being. © 2016 John

  6. Frequent inaccuracies in ABCD(2) scoring in non-stroke specialists' referrals to a daily Rapid Access Stroke Prevention service.

    2013-09-15

    The \\'accuracy\\' of age, blood pressure, clinical features, duration and diabetes (ABCD(2)) scoring by non-stroke specialists referring patients to a daily Rapid Access Stroke Prevention (RASP) service is unclear, as is the accuracy of ABCD(2) scoring by trainee residents. In this prospective study, referrals were classified as \\'confirmed TIAs\\' if the stroke specialist confirmed a clinical diagnosis of possible, probable or definite TIA, and \\'non-TIAs\\' if patients had a TIA mimic or completed stroke. ABCD(2) scores from referring physicians were compared with scores by experienced stroke specialists and neurology\\/geriatric medicine residents at a daily RASP clinic; inter-observer agreement was examined. Data from 101 referrals were analysed (mean age=60.0years, 58% male). The median interval between referral and clinic assessment was 1day. Of 101 referrals, 52 (52%) were \\'non-TIAs\\': 45 (86%) of 52 were \\'TIA mimics\\' and 7 (14%) of 52 were completed strokes. There was only \\'fair\\' agreement in total ABCD(2) scoring between referring physicians and stroke specialists (κ=0.37). Agreement was \\'excellent\\' between residents and stroke specialists (κ=0.91). Twenty of 29 patients scored as \\'moderate to high risk\\' (score 4-6) by stroke specialists were scored \\'low risk\\' (score 0-3) by referring physicians. ABCD(2) scoring by referring doctors is frequently inaccurate, with a tendency to underestimate stroke risk. These findings emphasise the importance of urgent specialist assessment of suspected TIA patients, and that ABCD(2) scores by non-stroke specialists cannot be relied upon in isolation to risk-stratify patients. Inter-observer agreement in ABCD(2) scoring was \\'excellent\\' between residents and stroke specialists, indicating short-term training may improve accuracy.

    2005-12-01

    Heart disease and stroke, the principal components of cardiovascular disease (CVD), are the first and third leading causes of death in the United States. In 2002, employers representing 88 companies in the United States paid an average of 18,618 dollars per employee for health and productivity-related costs. A sizable portion of these costs are related to CVD. Employers can yield a 3 dollar to 6 dollar return on investment for each dollar invested over a 2 to 5 year period and improve employee cardiovascular health by investing in comprehensive worksite health-promotion programs, and by choosing health plans that provide adequate coverage and support for essential preventive services. The most effective interventions in worksites are those that provide sustained individual follow-up risk factor education and counseling and other interventions within the context of a comprehensive health-promotion program: (1) screening, health risk assessments, and referrals; (2) environmental supports for behavior change (e.g., access to healthy food choices); (3) financial and other incentives; and (4) corporate policies that support healthy lifestyles (e.g., tobacco-free policies). The most effective practices in healthcare settings include systems that use (1) standardized treatment and prevention protocols consistent with national guidelines, (2) multidisciplinary clinical care teams to deliver quality patient care, (3) clinics that specialize in treating/preventing risk factors, (4) physician and patient reminders, and (5) electronic medical records. Comprehensive worksite health-promotion programs, health plans that cover preventive benefits, and effective healthcare systems will have the greatest impact on heart disease and stroke and are likely to reduce employers' health and productivity-related costs.

    Senoo, Keitaro; Lane, Deirdre A; Lip, Gregory Y H

    2014-09-01

    The availability of 4 non-vitamin K oral anticoagulants (NOACs), that is, dabigatran, rivaroxaban, apixaban, and edoxaban, has changed the landscape of stroke prevention in patients with atrial fibrillation. This review article provides an overview of the 4 phase III studies that have compared these NOACs, examining major outcomes of efficacy and safety. A range of practical questions relating to the NOACs have emerged, including topics such as patient selection, treating patients with renal impairment, treating elderly patients, and combining anticoagulant therapy with antiplatelet drugs. We also address the interaction of various patient characteristics with the treatments and suggest the features can assist the physician in the choice of a particular NOAC for a particular patient(s).

    Raposo, Maria Filomena de Jesus; de Morais, Alcina Maria Miranda Bernardo

    2015-03-15

    This review focuses on and discusses the primary phytochemicals present in microalgal biomass - carotenoids, phenolic compounds, antioxidant vitamins, sterols, and polyunsaturated fatty acids - and also on the exopolysaccharides, which are produced by some types of microalgae and may play a significant role in the prevention of cardiovascular diseases (CVD) and strokes. We have listed several preclinical trials and clinical studies supporting the health benefits that most of these compounds may provide. Microalgae are very easy to grow and are not vulnerable to contaminants when grown under controlled conditions. Proper handling and growth conditions may improve the production of phytochemicals. Therefore, they may represent an excellent source of nutraceuticals and food supplements once their safety as a food supplement has been confirmed. Copyright © 2014 Elsevier Inc.

    Full Text Available Introduction: Management of stroke in the remote rural areas in India faces major challenges because of lack of awareness. Stroke care services can be optimally implemented only if the communities have an understanding of the disease. Method: A population based, cross sectional survey of an adult general population sample between the ages of 31-60 years in a rural block in Tamil Nadu, India was carried out to study their knowledge, attitude, beliefs about cause, signs and symptoms, preventive measures and treatment options of stroke. Results: Of the 174 subjects studied only 69% were aware of the term stroke and 63% were able to list the symptoms. Only a little more than half the participants (58% were aware that diabetes, smoking and hypertension are risk factors for stroke. None of the participants were aware of the endovascular thrombolysis injection for better recovery from stroke. About quarter (23% of the participants did not think that the stroke is an emergency condition and they need to take the patient urgently to the hospital. Only 56% of the participants had checked their blood pressure and 49% for diabetes. A history of having either hypertension or diabetes and stroke in the family was the only factor that was significantly associated with better awareness (p=<0.001 independent of other potential facilitating factors including age, occupation, education and gender. Conclusion: There is a need to educate the rural communities about the risk factors, how to recognize the onset, the preventive measures and optimum care of stroke to reduce the burden.

    Spence, J David

    2016-10-01

    Elevated levels of total homocysteine impair endothelial dysfunction and increase thrombosis. Homocysteine is causal in animal models, and in human studies, elevated total homocysteine is significantly associated with carotid atherosclerosis, lacunar infarction, and markedly increased risk of stroke in atrial fibrillation. Because two of the early large trials of B vitamin therapy (Vitamin Intervention for Stroke Prevention and the Norwegian Vitamin Study) did not show any reduction of stroke, and the Heart Outcomes Prevention Evaluation 2 trial was mistakenly interpreted as not showing a reduction of stroke (because the authors could not think of a biological difference between stroke and myocardial infarction), there has been widespread pessimism regarding treatment to lower total homocysteine for stroke prevention. However, the Heart Outcomes Prevention Evaluation 2 trial, the French trial of folic acid and omega three oils, the Vitamins to Prevent Stroke subgroup excluding antiplatelet therapy all showed a significant reduction of stroke. Reasons why the Vitamin Intervention for Stroke Prevention trial were negative included folate fortification in North America, provision of injections of B12 to patients with low baseline serum B12, and as it turns out, harm from cyanide in cyanocobalamin among participants with impaired renal function. In the Diabetic Intervention with Vitamins in Nephropathy trial, B vitamins including cyanocobalamin were harmful, and in a Vitamin Intervention for Stroke Prevention subgroup excluding participants who received B12 injections and those with impaired renal function, there was a statistically significant reduction of stroke/myocardial infarction/vascular death. In 2015, the China Stroke Primary Prevention Trial (CSPPT), in over 20,000 participants followed for 5 years, showed a significant reduction of stroke with folic acid in a setting where folate fortification has not been implemented. In the setting of folate fortification

    2010-06-01

    Despite advances in stroke treatment in the United States, stroke remains the third leading cause of death among Americans and the leading cause of serious, long-term disability in the United States. About 780,000 Americans will have a new or recurrent stroke this year. Each year, about 60,000 more women than men have a stroke. African Americans have almost twice the risk of first-ever strokes compared with Whites. Minority populations are less likely to know all stroke symptoms and far less likely to know all heart attack symptoms. There are many benefits of early treatment of stroke, yet most minorities do not get this treatment because they do not recognize the warning signs, risk factors, and prevention of stroke. The objective of this intervention course was to increase the students' knowledge and awareness of stroke, warning signs, risk factors, and prevention. Developing community-based stroke prevention intervention courses in minority communities is a good strategy to reduce morbidity and mortality and help to eliminate health disparities in minority communities.

    We evaluated the impact of a primary stroke center (PSC) destination policy in a major metropolitan city and used geographic modeling to evaluate expected changes for a comprehensive stroke center policy. We identified suspected stroke emergency medical services encounters from 1/1/2004 to 12/31/2013 in Philadelphia, PA. Transport times were compared before and after initiation of a PSC destination policy on 10/3/2011. Geographic modeling estimated the impact of bypassing the closest hospital for the closest PSC and for the closest comprehensive stroke center. There were 2 326 943 emergency medical services runs during the study period, of which 15 099 had a provider diagnosis of stroke. Bypassing the closest hospital for a PSC was common before the official policy and increased steadily over time. Geographic modeling suggested that bypassing the closest hospital in favor of the closest PSC adds a median of 3.1 minutes to transport time. Bypassing to the closest comprehensive stroke center would add a median of 8.3 minutes. Within a large metropolitan area, the time cost of routing patients preferentially to PSCs and comprehensive stroke centers is low. © 2018 American Heart Association, Inc.

    2011-07-01

    Full Text Available Background: Stroke is the third common cause of disability and death. Diagnosis of stroke is based on its clinical manifestations and/or observation of infarct in the neuroimaging. Standard battery of diagnostic investigations and classification criteria is required for detection of stroke etiology. Materials and Method: This review article deals with the diagnosis and management of brain infarction particularly in our country and is provided for non-neurologists. Using online scientific search engines and in some parts referring to laboratory archives constituted base of this review article.Results: Acute stroke management is almost similar in its various etiologies. Neuroprotective drugs have little value in acute stroke management. At present time, a few Iranian medical centers have infrastructure of thrombolysis therapy. Prevention of stroke is based on the detection and control of its risk factors. Aspirin, 80 mg per day is the most common drug for stroke prevention. Co-administration of aspirin 80 mg/d and Dipyridamole 200-400 mg/d increases the preventive effects of aspirin. Clopidogrel 75 mg/d is the stroke preventive drug of choice in patients with peptic ulcer and coronary artery disease. Co-administration of aspirin and clopidogrel is more effective in stroke prevention but has more hemorrhagic complications. Using warfarin for stroke prevention is suggested only in patients who have facilities for repetitive coagulation tests. Carotid endarterectomy is indicated in symptomatic patients with more than 70% stenosis of extracranial internal carotid artery, if performed only by vascular surgeons experienced in carotid surgery.Conclusion: Many stroke patients are managed by general practitioners and non-neurologists, e.g. internists, cardiologists and neurosurgeons. This review article provides continuous medical education according to Iranian medical curriculum

  20. Plain packaging policy: Preventing industry innovations.

    Al-Hamdani, Mohammed

    2017-04-20

    The pack is a marketing tool for the tobacco industry - its shape, colour, fonts, descriptors and logos attract and mislead smokers. Health warnings on cigarette packs serve as a knowledge reminder for smokers to quit smoking. Plain packaging eliminates brand imagery elements from cigarette packs and has many benefits, including the reduction of intention to smoke and the denormalization of smoking behaviour. The tobacco industry has devised pack and product marketing innovations that thwart the effectiveness of health warnings. Plain packaging policy needs to address these innovations by restricting their use and preventing them from undermining health warnings.

    pressure with a renin-angiotensin system inhibitor soon after a stroke has not been clearly established. We evaluated the effects of therapy with an angiotensin-receptor blocker, telmisartan, initiated early after a stroke. METHODS: In a multicenter trial involving 20,332 patients who recently had...... an ischemic stroke, we randomly assigned 10,146 to receive telmisartan (80 mg daily) and 10,186 to receive placebo. The primary outcome was recurrent stroke. Secondary outcomes were major cardiovascular events (death from cardiovascular causes, recurrent stroke, myocardial infarction, or new or worsening...... heart failure) and new-onset diabetes. RESULTS: The median interval from stroke to randomization was 15 days. During a mean follow-up of 2.5 years, the mean blood pressure was 3.8/2.0 mm Hg lower in the telmisartan group than in the placebo group. A total of 880 patients (8.7%) in the telmisartan group...

    To identify barriers and facilitators of medication adherence in patients with stroke along with their caregivers. Qualitative thematic analysis of posts about secondary prevention medications, informed by Perceptions and Practicalities Approach. Posts written by the UK stroke survivors and their family members taking part in the online forum of the Stroke Association, between 2004 and 2011. 84 participants: 49 stroke survivors, 33 caregivers, 2 not stated, identified using the keywords 'taking medication', 'pills', 'size', 'side-effects', 'routine', 'blister' as well as secondary prevention medication terms. Perceptions reducing the motivation to adhere included dealing with medication side effects, questioning doctors' prescribing practices and negative publicity about medications, especially in regard to statins. Caregivers faced difficulties with ensuring medications were taken while respecting the patient's decisions not to take tablets. They struggled in their role as advocates of patient's needs with healthcare professionals. Not experiencing side effects, attributing importance to medications, positive personal experiences of taking tablets and obtaining modification of treatment to manage side effects were facilitators of adherence. Key practical barriers included difficulties with swallowing tablets, dealing with the burden of treatment and drug cost. Using medication storage devices, following routines and getting help with medications from caregivers were important facilitators of adherence. An online stroke forum is a novel and valuable resource to investigate use of secondary prevention medications. Analysis of this forum highlighted significant barriers and facilitators of medication adherence faced by stroke survivors and their caregivers. Addressing perceptual and practical barriers highlighted here can inform the development of future interventions aimed at improving adherence to secondary prevention medication after stroke. © Article author

    Perinatal stroke leads to significant morbidity and long-term neurological and cognitive deficits. The pathophysiological mechanisms of brain damage depend on brain maturation at the time of stroke. To understand whether microglial cells limit injury after neonatal stroke by preserving neurovascular integrity, we subjected postnatal day 7 (P7) rats depleted of microglial cells, rats with inhibited microglial TGFbr2/ALK5 signaling, and corresponding controls, to transient middle cerebral arter...

    Healthy public policy plays an essential role in a comprehensive public health approach to preventing cancer and chronic disease. Public policies spread through the 'policy diffusion' process, enabling governments to learn from another's enacted policy solutions. The Prevention Policies Directory (the Directory), an online database of municipal, provincial/territorial, and federal cancer and chronic disease prevention policies from across Canada, was developed to facilitate the diffusion of healthy public policies and support the work of prevention researchers, practitioners, and policy specialists. This information technology solution was implemented, through a participatory engagement approach, as a communication channel or policy knowledge transfer tool. It also addressed the intrinsic shortcomings of environmental scanning for policy surveillance and monitoring. A combination of quantitative web metrics and qualitative anecdotal evidence have illustrated that the Directory is becoming an important tool for healthy public policy surveillance and policy diffusion in Canada.

    Stroke is the third leading cause of death and disability. Few studies have assessed the profile and adequacy of access to rehabilitation services after ischaemic stroke both in the inpatient and community setting. The objectives of the Action on Secondary Prevention Interventions and Rehabilitation in Stroke (ASPIRE-S) study were to assess the disability and rehabilitation profile, adherence with rehabilitation recommendations and needs of patients 6 months following hospital admission for stroke. A rehabilitation prescription was completed before hospital discharge for each participant, and adherence to this prescription was assessed at 6 months to determine whether patients received their recommended rehabilitation needs. Two hundred and fifty six patients were recruited to ASPIRE-S. The average age was 69 (SD 12.8). A majority (n = 221, 86%) were referred to the hospital multidisciplinary team, 59% (n = 132) were referred to all services (physiotherapy (PT), occupational therapy (OT), speech and language therapy (SLT)). Fifty-four percent (n = 119) of patients (seen by the multidisciplinary team) were referred for further rehabilitation in the community on discharge. Of these 119 patients, 112 (95%) recalled receiving community rehabilitation services. However, while most (68%) patients were referred for several disciplines (PT, OT, SLT), the most commonly recalled therapy (55%) was from a single discipline. The most commonly recommended frequency of therapy required was on a weekly basis. Sixty-one patients (51%) reported a delay in services, with some still awaiting services at 6 months. Results from this prospective study revealed that a significant number of patients (57%) did not receive the therapy recommended on discharge. Future initiatives should include the development of policies, which support more effective, equitable multidisciplinary rehabilitation for stroke patients in the community. © 2016 S.

    Full Text Available Abstract Background Neuroserpin, primarily localized to CNS neurons, inhibits the adverse effects of tissue-type plasminogen activator (tPA on the neurovascular unit and has neuroprotective effects in animal models of ischemic stroke. We sought to evaluate the association of neuroserpin polymorphisms with risk for ischemic stroke among young women. Methods A population-based case-control study of stroke among women aged 15–49 identified 224 cases of first ischemic stroke (47.3% African-American and 211 age-matched control subjects (43.1% African-American. Neuroserpin single nucleotide polymorphisms (SNPs chosen through HapMap were genotyped in the study population and assessed for association with stroke. Results Of the five SNPs analyzed, the A allele (frequency; Caucasian = 0.56, African-American = 0.42 of SNP rs6797312 located in intron 1 was associated with stroke in an age-adjusted dominant model (AA and AT vs. TT among Caucasians (OR = 2.05, p = 0.023 but not African-Americans (OR = 0.71, p = 0.387. Models adjusting for other risk factors strengthened the association. Race-specific haplotype analyses, inclusive of SNP rs6797312, again demonstrated significant associations with stroke among Caucasians only. Conclusion This study provides the first evidence that neuroserpin is associated with early-onset ischemic stroke among Caucasian women.

    Full Text Available Stroke and other cerebrovascular diseases are among the most common causes of death worldwide. Prevention of modifiable risk factors is a cost-effective approach to decrease the risk of stroke. Oxidative stress is regarded as the major flexible operative agent in ischemic brain damage. This review presents recent scientific advances in understanding the role of carotenoids as antioxidants in lowering stroke risk based on observational studies. We searched Medline using the following terms: (Carotenoids [MeSH] OR Carotenes [tiab] OR Carotene [tiab] OR “lycopene [Supplementary Concept]” [MeSH] OR lycopene [tiab] OR beta-Carotene [tiab] AND (stroke [MeSH] OR stroke [tiab] OR “Cerebrovascular Accident” [tiab] OR “Cerebrovascular Apoplexy” [tiab] OR “Brain Vascular Accident” [tiab] OR “Cerebrovascular Stroke” [tiab] AND (“oxidative stress” [MeSH] OR “oxidative stress”[tiab]. This search considered papers that had been published between 2000 and 2017. Recent studies indicated that high dietary intake of six main carotenoids (i.e., lycopene, <- and ®-carotene, lutein, zeaxanthin, and astaxanthin was associated with reduced risk of stroke and other cardiovascular outcomes. However, the main mechanism of the action of these nutrients was not identified, and multiple mechanisms except antioxidant activity were suggested to be involved in the observed beneficial effects. The dietary intake of six major carotenoids should be promoted as this may have a substantial positive effect on stroke prevention and stroke mortality reduction.

    This research was aimed at clarifying whether high dietary fiber intake has an impact on incidence and risk of stroke at a population level. In 1647 unselected subjects, dietary fiber intake (DFI) was detected in a 12-year population-based study, using other dietary variables, anagraphics, biometrics, blood pressure, heart rate, blood lipids, glucose, insulin, uricaemia, fibrinogenaemia, erytrosedimentation rate, diabetes, insulin resistance, smoking, pulmonary disease and left ventricular hypertrophy as covariables. In adjusted Cox models, high DFI reduced the risk of stroke. In analysis based on quintiles of fiber intake adjusted for confounders, HR for incidence of stroke was lower when the daily intake of soluble fiber was >25 g or that of insoluble fiber was >47 g. In multivariate analyses, using these values as cut-off of DFI, the risk of stroke was lower in those intaking more that the cut-off of soluble (HR 0.31, 0.17-0.55) or insoluble (HR 0.35, 0.19-0.63) fiber. Incidence of stroke was also lower (-50%, p < 0.003 and -46%, p < 0.01, respectively). Higher dietary DFI is inversely and independently associated to incidence and risk of stroke in general population.

  15. Which Patent Foramen Ovales Need Closure to Prevent Cryptogenic Strokes?

    Science.gov (United States)

    Dalen, James E; Alpert, Joseph S

    2018-03-01

    Patients with cryptogenic strokes are more likely to have a patent foremen ovale than in the general population. It is speculated that these strokes are due to paradoxical embolism, that is, passage of a venous thrombus across the patent foremen ovale to enter the arterial circulation, resulting in an embolic stroke. Venous thromboembolism is rarely present in these cases of cryptogenic stroke. Thousands of patients with cryptogenic strokes have undergone transcatheter closure of their patent foremen ovale via a variety of devices. The first 3 randomized clinical trials comparing patent foremen ovale closure with medical therapy failed to show a significant advantage of patent foremen ovale closure. Three additional trials reported in 2017 had longer years of follow-up and demonstrated an advantage of patent foremen ovale closure versus medical therapy. Analysis of their data indicated that patent foremen ovale closure in patients with an atrial septal aneurysm in addition to a patent foremen ovale had a very significant decrease in cryptogenic strokes (P patent foremen ovale closure (P = .37). Aneurysms of the atrial septum are easily recognized by echocardiography and are present in approximately one-third of patients with patent foremen ovales. These data suggest that closure of patent foremen ovales in patients with an atrial septal aneurysm is indicated. In patients with a patent foremen ovale without an aneurysm of the atrial septum, patent foremen ovale closure is not indicated. Copyright © 2018 Elsevier Inc. All rights reserved.

    Primary prevention of stroke and transient ischemic attack (TIA) is important to reduce the burden of these conditions; however, prescribing of prevention drugs is suboptimal. We aimed to identify individual clinical and demographic characteristics associated with potential missed opportunities for prevention therapy with lipid-lowering, anticoagulant, or antihypertensive drugs before stroke/TIA. We analyzed anonymized electronic primary care records from a UK primary care database that covers 561 family practices. Patients with first-ever stroke/TIA, ≥18 years, with diagnosis between January 1, 2009, and December 31, 2013, were included. Missed opportunities for prevention were defined as people with clinical indications for lipid-lowering, anticoagulant, or antihypertensive drugs but not prescribed these drugs before their stroke/TIA. Mixed-effect logistic regression models evaluated the relationship between missed opportunities and individual clinical/demographic characteristics. The inclusion criteria were met by 29 043 people with stroke/TIA. Patients with coronary heart disease, chronic kidney disease, peripheral arterial disease, or diabetes mellitus were at less risk of a missed opportunity for prescription of lipid-lowering and antihypertensive drugs. However, patients with a 10-year cardiovascular disease risk ≥20% but without these diagnoses had increased risk of having a missed opportunity for prescription of lipid-lowering drugs or antihypertensive drugs. Women were less likely to be prescribed anticoagulants but more likely to be prescribed antihypertensive drugs. The elderly (≥85 years of age) were less likely to be prescribed all 3 prevention drugs, compared with people aged 75 to 79 years. Knowing the patient characteristics predictive of missed opportunities for stroke prevention may help primary care identify and appropriately manage these patients. Improving the management of these groups may reduce their risk and potentially prevent

    Full Text Available Ji-Guang WangCentre for Epidemiological Studies and Clinical Trials, Ruijin Hospital, Shanghai Jiaotong University School of Medicine, Shanghai, ChinaAbstract: Stroke is a leading cause of death and disability worldwide. The importance of lowering blood pressure for reducing the risk of stroke is well established. However, not all the benefits of antihypertensive treatments in stroke can be accounted for by reductions in BP and there may be differences between antihypertensive classes as to which provides optimal protection. Dihydropyridine calcium channel blockers, such as amlodipine, and angiotensin receptor blockers, such as valsartan, represent the two antihypertensive drug classes with the strongest supportive data for the prevention of stroke. Therefore, when combination therapy is required, a combination of these two antihypertensive classes represents a logical approach.Keywords: stroke, angiotensin, calcium channel, cerebrovascular, hypertension, blood pressure

    Cardioembolic strokes account for one-sixth of all strokes and are an important potentially preventable cause of morbidity and mortality. Vitamin K antagonists (e.g., warfarin) are effective for the prevention of cardioembolic stroke in patients with atrial fibrillation (AF) and in those with mechanical heart valves but because of their inherent limitations are underutilized and often suboptimally managed. Antiplatelet therapies have been the only alternatives to warfarin for stroke prevention in AF but although they are safer and more convenient they are much less efficacious. The advent of new oral anticoagulant drugs offers the potential to reduce the burden of cardioembolic stroke by providing access to effective, safe, and more convenient therapies. New oral anticoagulants have begun to replace warfarin for stroke prevention in some patients with AF, based on the favorable results of recently completed phase III randomized controlled trials, and provide for the first time an alternative to antiplatelet therapy for patients deemed unsuitable for warfarin. The promise of the new oral anticoagulants in patients with mechanical heart valves is currently being tested in a phase II trial. If efficacy and safety are demonstrated, the new oral anticoagulants will provide an alternative to warfarin for patients with mechanical heart valves and may also lead to increased use of mechanical valves for patients who would not have received them in the past because of the requirement for long term warfarin therapy.

    Climate change prevention has become one of the major concerns of environmental policy in the Netherlands. The Dutch government has set definite targets for CO 2 emissions in the coming decade. These targets and the measures necessary to reach them are described in the paper. In addition, the technical feasibility of realizing the Toronto objective of a 20% reduction in CO 2 emissions by the year 2005 in the Netherlands is discussed. It appears that energy conservation options are most crucial for the short-term, but that eventually new supply technologies are needed to obtain drastic reductions in the long term. The increased need for research and development efforts has led to two innovative research programmes on sustainable energy development in the Netherlands. The ENGINE (ENergy Generation In the Natural Environment) programme is implemented by the Netherlands Energy Research Foundation (ECN) and addresses the specific problems associated with the three major components of supply: cleanliness in the case of fossil fuels, safety in the case of nuclear energy, and costs in the case of renewable sources. The complementary SYRENE (SYstem integration of Renewable ENergy and End use) is implemented by the Netherlands Agency for Energy and Environment (NOVEM) and addresses the system aspects of sustainable energy development. The objectives and approaches of these two programmes are briefly presented. 1 fig., 1 tab., 4 refs

    In sickle cell disease, a common inherited haemoglobin disorder, abnormal haemoglobin distorts red blood cells, causing anaemia, vaso-occlusion and dysfunction in most body organs. Without intervention, stroke affects around 10% of children with sickle cell anaemia (HbSS) and recurrence is likely. Chronic blood transfusion dilutes the sickled red blood cells, reducing the risk of vaso-occlusion and stroke. However, side effects can be severe. To assess risks and benefits of chronic blood transfusion regimens in people with sickle cell disease to prevent first stroke or recurrences. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register, comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and conference proceedings.Date of the latest search of the Group's Haemoglobinopathies Trials Register: 28 January 2013. Randomised and quasi-randomised controlled trials comparing blood transfusion as prophylaxis for stroke in people with sickle cell disease to alternative or no treatment. Both authors independently assessed the risk of bias of the included trials and extracted data. Searches identified three eligible randomised trials (n = 342). The first two trials addressed the use of chronic transfusion to prevent primary stroke; the third utilized the drug hydroxycarbamide (hydroxyurea) and phlebotomy to prevent both recurrent (secondary) stroke and iron overload in patients who had already experienced an initial stroke. In the first trial (STOP) a chronic transfusion regimen for maintaining sickle haemoglobin lower than 30% was compared with standard care in 130 children with sickle cell disease judged (through transcranial Doppler ultrasonography) as high-risk for first stroke. During the trial, 11 children in the standard care group suffered a stroke compared to one in the transfusion group, odds ratio 0.08 (95% confidence interval 0.01 to 0.66). This meant the trial was

    Atrial fibrillation (AF) is associated with significant mortality and morbidity, and stroke represents the most-feared complication. Consequently, AF treatment has focused on thromboprophylaxis, with warfarin as the mainstay of therapy. However, concerns over ease of use and safety have limited its use. Three novel oral anticoagulants have been approved for use in stroke prevention in AF based on randomized data: 1) dabigatran, studied in Randomized Evaluation of Long-term Anticoagulation Therapy (RE-LY); 2) rivaroxaban, studied in Rivaroxaban Once-daily, Oral, Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF); and 3) apixaban, studied in Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE). In this review, we focus on apixaban and discuss subgroup analyses that have been performed in the three trials comparing novel oral anticoagulants with warfarin. We conclude with recommendations regarding further investigations.

    Full Text Available This article considers the pathogenetic mechanisms of stroke in arterial hypertension (AH with special emphasis on comorbid neurological and cardiac disorders. It presents the cardiac and neurological aspects of the current strategy of medical therapy within the secondary prevention of poststroke cardiovascular events. The secondary prevention of cardiovascular events in patients who have sustained ischemic stroke in the presence of AH involves the use of not only antihypertensive drugs, but also adequate antiplatelet therapy and statins. The most important part is assigned to the prevention and treatment of cognitive impairments, which also promotes increased patient treatment adherence and improved poststroke prognosis, including longer survival and better quality of life.

    Full Text Available We report a case of progressive ischemic stroke due to a mobile plaque, in which carotid artery stenting successfully prevented further infarctions. A 78-year-old man developed acute multiple infarcts in the right hemisphere, and a duplex ultrasound showed a mobile plaque involving the bifurcation of the left common carotid artery. Maximal medical therapy failed to prevent further infarcts, and the number of infarcts increased with his neurological deterioration. Our present case suggests that the deployment of a closed-cell stent is effective to prevent the progression of the ischemic stroke due to the mobile plaque.

    Full Text Available Abstract Background This study aimed to inform the design of a pragmatic trial of stroke prevention in primary care by evaluating data recorded in electronic patient records (EPRs as potential outcome measures. The study also evaluated achievement of recommended standards of care; variation between family practices; and changes in risk factor values from before to after stroke. Methods Data from the UK General Practice Research Database (GPRD were analysed for 22,730 participants with an index first stroke between 2003 and 2006 from 414 family practices. For each subject, the EPR was evaluated for the 12 months before and after stroke. Measures relevant to stroke secondary prevention were analysed including blood pressure (BP, cholesterol, smoking, alcohol use, body mass index (BMI, atrial fibrillation, utilisation of antihypertensive, antiplatelet and cholesterol lowering drugs. Intraclass correlation coefficients (ICC were estimated by family practice. Random effects models were fitted to evaluate changes in risk factor values over time. Results In the 12 months following stroke, BP was recorded for 90%, cholesterol for 70% and body mass index (BMI for 47%. ICCs by family practice ranged from 0.02 for BP and BMI to 0.05 for LDL and HDL cholesterol. For subjects with records available both before and after stroke, the mean reductions from before to after stroke were: mean systolic BP, 6.02 mm Hg; diastolic BP, 2.78 mm Hg; total cholesterol, 0.60 mmol/l; BMI, 0.34 Kg/m2. There was an absolute reduction in smokers of 5% and heavy drinkers of 4%. The proportion of stroke patients within the recommended guidelines varied from less than a third (29% for systolic BP, just over half for BMI (54%, and over 90% (92% on alcohol consumption. Conclusions Electronic patient records have potential for evaluation of outcomes in pragmatic trials of stroke secondary prevention. Stroke prevention interventions in primary care remain suboptimal but important

According to the Jadad Scale, 8 clinical studies were evaluated as high-quality literature (score ≥ 4, and the remaining 7 were low-quality literature (score < 4. All of systematic reviews (including Meta-analyses and reviews were of high quality. The results were as follows: 1 the use of dabigatran in stroke patients, especially Asian patients, with non-valvular atrial fibrillation showed no inferior efficiency and lower risk for major bleeding for the secondary prevention of stroke than warfarin, while the elder should be given lower dosage and blood concentration of drug might be in need of monitoring. 2 Applying dabigatran for the secondary prevention of stroke in patients with mechanical valve replacement must be cautious. Insufficient evidence had shown its inferiority in both efficiency and safety when compared to warfarin. 3 Large-scale clinical trials are needed to provide evidence for the application of dabigatran in valvular heart

    Established risk factors do not fully identify patients at risk for recurrent stroke. The SPARCL trial (Stroke Prevention by Aggressive Reduction in Cholesterol Levels) evaluated the effect of atorvastatin on stroke risk in patients with a recent stroke or transient ischemic attack and no known coronary heart disease. This analysis explored the relationships between 13 plasma biomarkers assessed at trial enrollment and the occurrence of outcome strokes. We conducted a case-cohort study of 2176 participants; 562 had outcome strokes and 1614 were selected randomly from those without outcome strokes. Time to stroke was evaluated by Cox proportional hazards models. There was no association between time to stroke and lipoprotein-associated phospholipase A 2 , monocyte chemoattractant protein-1, resistin, matrix metalloproteinase-9, N-terminal fragment of pro-B-type natriuretic peptide, soluble vascular cell adhesion molecule-1, soluble intercellular adhesion molecule-1, or soluble CD40 ligand.

    Full Text Available Objective To evaluate the evidence of migraine increasing the risk of stroke, so as to provide evidence-based foundation for primary prevention of stroke in patients with migraine.  Methods Taking migraine or migraine with aura, prevention and control, ischemia, hemorrhagic stroke, treatment or therapy as search terms, retrieve in databases such as PubMed and ScienceDirect, assisted by manual searching, in order to collect relevant literatures including clinical guidelines, systematic reviews, Meta-analysis, randomized controlled trials, clinical controlled trials, retrospective case analysis, case-observation studies and reviews. Jadad Scale was used to evaluate the quality of literature.  Results Twenty-four related articles were finally selected, including 5 clinical guidelines, 2 systematic reviews, 4 Meta-analyses, 2 randomized controlled trials, 10 case-observation studies and 1 review. Among them 20 were of high quality, while 4 were of low quality. The results were as follows: 1 migraine, particularly migraine with aura, significantly increased the risk of ischemic stroke, and the risk of women was higher than men. Smoking and oral contraceptives further increased the risk of stroke. 2 The risk of hemorrhagic stroke in migraine with aura patients was higher than that in general population. Migraine without aura did not appear to increase the risk of hemorrhagic stroke, and migraine was an independent risk factor for aneurysm rupture. 3 Frequency of migraine attacks, especially migraine with aura, and risk of ischemic stroke was positively correlated. 4 Patent foramen ovale (PFO was more common in young patients with cryptogenic stroke and migraineurs. However, closure of PFO was not indicated for preventing stroke in migraineurs. 5 Triptans, which was used to treat acute migraine, with a vasoconstrictor effect, may increase the risk of stroke, therefore prophylactic treatment of migraine was very important.  Conclusions Smoking

    Obesity is seen as a worldwide chronic disease with high prevalence that has been associated with increased morbidity from many conditions including stroke, which is the third leading cause of death in developed countries and a leading cause of severe long-term disability. The causal association between overweight or obesity and stroke is unclear and there is no definite study clarifying the role of obesity treatment in the prevention of a first stroke (primary prevention). Given the prevalence of stroke and the enormous health and economic cost of the disease, it is important to establish the possible impact of weight reduction per se on stroke incidence. To assess the effects of weight reduction in people with overweight or obesity on stroke incidence. MEDLINE, EMBASE, The Cochrane Library, LILACS, databases of ongoing trials and reference lists were used to identify relevant trials. The last search was conducted in April 2006. Randomised controlled trials comparing any intervention for weight reduction (single or combined) with placebo or no intervention in overweight or obese people. No trials were found in the literature for inclusion in this review. There are currently no results to be reported. Obesity seems to be associated with an increased risk of stroke and it has been suggested that weight loss may lead to a reduction of stroke occurrence. However, this hypothesis is not based on strong scientific evidence resulting from randomised controlled clinical trials. This systematic review identified the urgent need for well-designed, adequately-powered, multi centre randomised controlled trials assessing the effects of weight reduction in persons with overweight or obesity on stroke occurrence.

    Cervical artery dissections involve the carotid or vertebral arteries. Although the overall incidence is low, they remain a common cause of stroke in children, young adults, and trauma patients. Symptoms such as headache, neck pain, and dizziness are commonly seen in the emergency department, but may not be apparent in the obtunded trauma patient. A missed diagnosis of cervical artery dissection can result in devastating neurological sequelae, so emergency clinicians must act quickly to recognize this event and begin treatment as soon as possible while neurological consultation is obtained. This issue reviews the evidence in applying advanced screening criteria and choosing imaging and antithrombotic treatment strategies for patients with cervical artery dissections to reduce the occurrence of ischemic stroke.

    Perinatal stroke leads to significant morbidity and long-term neurological and cognitive deficits. The pathophysiological mechanisms of brain damage depend on brain maturation at the time of stroke. To understand whether microglial cells limit injury after neonatal stroke by preserving neurovascular integrity, we subjected postnatal day 7 (P7) rats depleted of microglial cells, rats with inhibited microglial TGFbr2/ALK5 signaling, and corresponding controls, to transient middle cerebral artery occlusion (tMCAO). Microglial depletion by intracerebral injection of liposome-encapsulated clodronate at P5 significantly reduced vessel coverage and triggered hemorrhages in injured regions 24 h after tMCAO. Lack of microglia did not alter expression or intracellular redistribution of several tight junction proteins, did not affect degradation of collagen IV induced by the tMCAO, but altered cell types producing TGFβ1 and the phosphorylation and intracellular distribution of SMAD2/3. Selective inhibition of TGFbr2/ALK5 signaling in microglia via intracerebral liposome-encapsulated SB-431542 delivery triggered hemorrhages after tMCAO, demonstrating that TGFβ1/TGFbr2/ALK5 signaling in microglia protects from hemorrhages. Consistent with observations in neonatal rats, depletion of microglia before tMCAO in P9 Cx3cr1(GFP/+)/Ccr2(RFP/+) mice exacerbated injury and induced hemorrhages at 24 h. The effects were independent of infiltration of Ccr2(RFP/+) monocytes into injured regions. Cumulatively, in two species, we show that microglial cells protect neonatal brain from hemorrhage after acute ischemic stroke. Copyright © 2016 the authors 0270-6474/16/362881-13$15.00/0.

    With improved life expectancy and the aging population, the global burden of atrial fibrillation (AF) continues to increase, and with AF comes an estimated fivefold increased risk of ischaemic stroke. Prophylactic anticoagulant therapy is more effective in reducing the risk of ischaemic stroke in AF patients than acetylsalicylic acid or dual-antiplatelet therapy combining ASA with clopidogrel. Non-vitamin K antagonist oral anticoagulants are the standard of care for stroke prevention in patients with non-valvular AF. The optimal anticoagulant strategy to prevent thromboembolism in AF patients who are undergoing percutaneous coronary intervention and stenting, those who have undergone successful transcatheter aortic valve replacement and those with embolic stroke of undetermined source are areas of ongoing research. This article provides an update on three randomized controlled trials of rivaroxaban, a direct, oral factor Xa inhibitor, that are complete or are ongoing, in these unmet areas of stroke prevention: oPen-label, randomized, controlled, multicentre study explorIng twO treatmeNt stratEgiEs of Rivaroxaban and a dose-adjusted oral vitamin K antagonist treatment strategy in patients with Atrial Fibrillation who undergo Percutaneous Coronary Intervention (PIONEER AF-PCI) trial; the New Approach riVaroxaban Inhibition of factor Xa in a Global trial vs Aspirin to prevenT Embolism in Embolic Stroke of Undetermined Source (NAVIGATE ESUS) trial and the Global study comparing a rivAroxaban-based antithrombotic strategy to an antipLatelet-based strategy after transcatheter aortIc vaLve rEplacement to Optimize clinical outcomes (GALILEO) trial. The data from these studies are anticipated to help address continuing challenges for a range of patients at risk of stroke. Schattauer.

    Stroke is a leading cause of death and disability affecting nearly 800,000 people in the United States every year. Obstructive sleep apnea (OSA) is found in over 60% of patients with stroke/transient ischemic attack (TIA) and identified as an independent stroke risk factor in large epidemiology studies and Canadian Stroke Prevention Guidelines (SPG) but not in the United States. The 2014 Secondary SPG recommend OSA screening and treatment as a consideration only, not a requirement. The twofold purpose of this article is, first, to present the evidence supporting OSA as an independent stroke risk factor in national SPG with mandatory recommendations and, second, to engage neuroscience nurses to incorporate OSA assessment and interventions into the nursing process and thereby promote excellence in stroke/TIA patient care. A systematic literature search was conducted in Medline, CINAHL, and PubMed to identify research from 2003 through 2013 on the independent risk, mortality, and prevalence relationship between OSA and stroke/TIA including recurrence and recovery outcomes with continuous positive airway pressure (CPAP) therapy. Twenty-eight research articles were reviewed: 14 observational cohorts, five case-control studies, four cross-sectional studies, and four randomized control trials representing 12 countries and 10,671 subjects. OSA is highly prevalent in patients with stroke/TIA independently increasing stroke risk. CPAP studies revealed reduced stroke recurrence and improved recovery with feasible initiation in stroke units. Patients with stroke/TIA have less OSA-associated daytime sleepiness and obesity, making the usual screening tools insufficient and CPAP adherence challenging. Treating OSA decreases stroke prevalence and mortality. OSA initiatives empower neuroscience nurses to integrate this OSA evidence into clinical practice and improve stroke/TIA patient outcomes.

    Full Text Available The purpose of the study was to comparatively analyze the rate of post-stroke depression and cognitive impairments in escitalopram (cipralex-treated and untreated (control patients. Emotional and affective cognitive symptoms, neurological deficit, and day-to-day activity were evaluated over time 1, 3, and 6 months after treatment. The results of the study indicated that escitalopram used to prevent depression in the acute phase of stroke provided a good effect. This drug caused a prompter recovery of cognitive impairments and reduced the pace of development of neurodegenerative disorders underlying the post-stroke 2D (depression and dementia syndrome. The study group was recorded to have more favorable functional outcomes of stroke and patient mobility indicators associated with lower disability rates.

    Drawing on the perspectives of stroke survivors, family members and domestic helpers, this study explores participants' experiences of self-perceived fall risk factors after stroke, common fall prevention strategies used, and challenges to community participation after a fall. Semi-structured interviews were conducted in Singapore with community-dwelling stroke survivors with a previous fall (n = 9), family caregivers (n = 4), and domestic helpers (n = 4) who have cared for a stroke survivor with a previous fall. Purposive sampling was used for recruitment; all interviews were audio-recorded with permission and transcribed. Thematic analysis was conducted using NVivo (v10) software. All participants shared their self-perceived intrinsic and extrinsic fall risk factors and main challenges after a fall. For stroke participants and family caregivers, motivational factors in developing safety strategies after a previous fall(s) include social connectedness, independent living and community participation. For family caregivers and domestic helpers, the stroke survivor's safety is their top priority, however this can also lead to over-protective behavior outside of the rehabilitation process. Reducing the risk of falls in community-dwelling stroke survivors seems to be more important than promoting community participation among caregivers. The study findings highlight that a structured and client-centered fall prevention program targeting stroke survivors and caregivers is needed in Singapore. Implications for rehabilitation Falls after stroke can lead to functional decline in gait and mobility and restricted self-care activities. Community-dwelling stroke survivors develop adaptive safety strategies after a fall and want to be socially connected. However, caregivers see the safety of the stroke survivors as their top priority and demonstrate over-protective behaviors. Fall prevention programs for community-dwelling stroke survivors should target both stroke

    Supplementation with B vitamins for stroke prevention has been evaluated over the years, but which combination of B vitamins is optimal for stroke prevention is unclear. We performed a network meta-analysis to assess the impact of different combinations of B vitamins on risk of stroke. A total of 17 trials (86 393 patients) comparing 7 treatment strategies and placebo were included. A network meta-analysis combined all available direct and indirect treatment comparisons to evaluate the efficacy of B vitamin supplementation for all interventions. B vitamin supplementation was associated with reduced risk of stroke and cerebral hemorrhage. The risk of stroke was lower with folic acid plus vitamin B6 as compared with folic acid plus vitamin B12 and was lower with folic acid plus vitamin B6 plus vitamin B12 as compared with placebo or folic acid plus vitamin B12. The treatments ranked in order of efficacy for stroke, from higher to lower, were folic acid plus vitamin B6 > folic acid > folic acid plus vitamin B6 plus vitamin B12 > vitamin B6 plus vitamin B12 > niacin > vitamin B6 > placebo > folic acid plus vitamin B12. B vitamin supplementation was associated with reduced risk of stroke; different B vitamins and their combined treatments had different efficacy on stroke prevention. Folic acid plus vitamin B6 might be the optimal therapy for stroke prevention. Folic acid and vitamin B6 were both valuable for stroke prevention. The efficacy of vitamin B12 remains to be studied.

    Full Text Available Blood pressure reduction is an important and effective strategy in stroke prevention in hypertensives. Recently, we found that baroreflex restoration was also crucial in stroke prevention. The present work was designed to test the hypothesis that a combination of blood pressure reduction and baroreflex restoration may be a new strategy for stroke prevention. In Experiment 1, the effects of ketanserin (0.3, 1, 3, 10 mg/kg, amlodipine (0.3, 1, 2, 3 mg/kg and their combination (1+0.3, 1+1, 1+2, 1+3 mg/kg on blood pressure and baroreflex sensitivity (BRS of stroke-prone spontaneously hypertensive rats (SHR-SP were determined under conscious state. It was found that both amlodipine and ketanserin decreased blood pressure dose-dependently. Ketanserin enfanced BRS from a very small dose but amlodipine enfanced BRS only at largest dose used. At the dose of 1 + 2 mg/kg (ketanserin + amlodipine, the combination possessed the largest synergism on blood pressure reduction. In Experiments 2 and 3, SHR-SP and two-kidney, two-clip (2K2C renovascular hypertensive rats received life-long treatments with ketanserin (1 mg/kg and amlodipine (2 mg/kg or their combination (0.5+1, 1+2, 2+4 mg/kg. The survival time was recorded and the brain lesion was examined. It was found that all kinds of treatments prolonged the survival time of SHR-SP and 2K2C rats. The combination possessed a significantly better effect on stroke prevention than mono-therapies. In conclusion, combination of blood pressure reduction and baroreflex restoration may be a new strategy for the prevention of stroke in hypertension.

    Compared to medical therapy alone, percutaneous closure of patent foramen ovale (PFO) further reduces risk of recurrent ischemic strokes in carefully selected young to middle-aged patients with a recent cryptogenic ischemic stroke. The objective of this study was to evaluate the cost-effectiveness of this therapy in the context of the United Kingdom (UK) healthcare system. A Markov cohort model consisting of four health states (Stable after index stroke, Post-Minor Recurrent Stroke, Post-Moderate Recurrent Stroke, and Death) was developed to simulate the economic outcomes of device-based PFO closure compared to medical therapy. Recurrent stroke event rates were extracted from a randomized clinical trial (RESPECT) with a median of 5.9-year follow-up. Health utilities and costs were obtained from published sources. One-way and probabilistic sensitivity analyses (PSA) were performed to assess robustness. The model was discounted at 3.5% and reported in 2016 Pounds Sterling. Compared with medical therapy alone and using a willingness-to-pay (WTP) threshold of £20,000, PFO closure reached cost-effectiveness at 4.2 years. Cost-effectiveness ratios (ICERs) at 4, 10, and 20 years were ₤20,951, ₤6,887, and ₤2,158, respectively. PFO closure was cost-effective for 89% of PSA iterations at year 10. Sensitivity analyses showed that the model was robust. Considering the UK healthcare system perspective, percutaneous PFO closure in cryptogenic ischemic stroke patients is a cost-effective stroke prevention strategy compared to medical therapy alone. Its cost-effectiveness was driven by substantial reduction in recurrent strokes and patients' improved health-related quality-of-life.

    Full Text Available Stroke patients among all patients with somatic diseases are at one of the highest risks for venous thromboembolism (VTE. The proven risk factors for venous thrombosis in stroke are prolonged immobilization, elderly age, obesity, diabetes mellitus, and inherited coagulopathies. If no drug prevention is done, the course of stroke is complicated by deep vein thrombosis (DVT in 75% of the immobilized patients and pulmonary thromboembolism develops in 20%. At present there are mechanical, pharmacological, and combined DVT prevention strategies that may considerably lower the rate of pulmonary embolism. In stroke patients, the use of low-molecular-weight heparins (LMWH reduces therisk of DVT, without increasing the risk of hemorrhagic complications. Novel oral anticoagulants used to treat venous thrombosis and VTE in stroke patients are an equivalent alternative to LMWH therapy. Treatment with novel oral anticoagulants to prevent recurrent VTE is effective and safe and may be continued up to 1–2 years.

    The preventive effects of long-term treatment with arotinolol on the development of cerebral stroke were examined in SHRSP fed a high salt diet. Arotinolol (4.87 mg/kg per day for 20 weeks) prevented cerebral lesions, reduced signs of stroke and delayed early mortality but did not alter blood pressure from control SHRSP, when the administration of the drug was started before the onset of hypertension. At dosage levels similar to arotinolol, both pindolol and labetalol were less effective in preventing cerebral lesions despite lower blood pressure. Propranolol produced no detectable effect on blood pressure or frequency of cerebral lesions. Furthermore, arotinolol (4.27 mg/kg per day) markedly inhibited the development of stroke without blood pressure reduction, when the administration was started after the onset of severe hypertension. These results suggest that arotinolol is more effective in preventing cerebral stroke than pindolol, labetalol and propranolol, and that factors other than blood pressure reduction may be involved in this preventive effect.

    In Rivaroxaban Once Daily Oral Direct Factor Xa Inhibitor Compared With Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF) trial, rivaroxaban was noninferior to dose-adjusted warfarin in preventing stroke or systemic embolism among patients with nonvalvular atrial fibrillation at moderate to high stroke risk. Because of differences in patient demographics, epidemiology, and stroke risk management in East Asia, outcomes and relative effects of rivaroxaban versus warfarin were assessed to determine consistency among East Asians versus other ROCKET AF participants. Baseline demographics and interaction of treatment effects of rivaroxaban and warfarin among patients within East Asia and outside were assessed. A total of 932 (6.5%) ROCKET AF participants resided in East Asia. At baseline, East Asians had lower weight, creatinine clearance, and prior vitamin K antagonist use; higher prevalence of prior stroke; and less congestive heart failure and prior myocardial infarction than other participants. Despite higher absolute event rates for efficacy and safety outcomes in East Asians, the relative efficacy of rivaroxaban (20 mg once daily; 15 mg once daily for creatinine clearance of 30-49 mL/min) versus warfarin with respect to the primary efficacy end point (stroke/systemic embolism) was consistent among East Asians and non-East Asians (interaction P=0.666). Relative event rates for the major or nonmajor clinically relevant bleeding in patients treated with rivaroxaban and warfarin were consistent among East Asians and non-East Asians (interaction P=0.867). Observed relative efficacy and safety of rivaroxaban versus warfarin were similar among patients within and outside East Asia. Rivaroxaban, 20 mg once daily, is an alternative to warfarin for stroke prevention in East Asians with nonvalvular atrial fibrillation. © 2014 American Heart Association, Inc.

    Introduction Due to the large number of Road Traffic Injuries (RTIs) in Iran, authorities have implemented a number of policies for the prevention of RTIs. However, a scientific analysis of these policies has thus far been neglected. Therefore, this study was conducted for policy analysis of RTIs prevention in Iran. Methods This qualitative study with a case study approach was conducted in Iran during 2016 in two phases: First, by reviewing literature and documents of the past ten years, policies that have been executed to prevent RTIs in Iran were identified. In the second phase of the study, the identified policies were ranked by prioritization matrices. The two policies with the highest scores were selected. ‘Policy triangle framework’ was used for Policy analyzing. Stakeholders of these policies (42 people) were interviewed. Data were analyzed manually by implementing Content-Analysis methods. Results The policies of “pupil liaisons” and “safety belt” were selected for analysis from thirteen potential identified polices. The results of some studies revealed that safety belts had not been properly used in Iran (less than 80%). There was an eight-year hiatus between the approval of the safety belts policy and implementation of this policy. Eight actors were identified for safety belts policy. Lack of diligence in implementation of the policy, failing to pay adequate attention to education and the culture of driving, and failing to select an organization for the implementation of the policy, were identified as the main weaknesses of this policy. For ‘pupil liaisons’ policy, five actors were identified. Following the implementation of this policy, the number of penalties was reduced (17.9%). Neglecting scientific findings and individual-based nature of the policy were identified as the primary weaknesses of this policy. Conclusions Taking serious measures to properly execute the policy, educating people, selecting an efficient organization that is

    Intracranial pressure elevation, peaking three to seven post-stroke is well recognized following large strokes. Data following small-moderate stroke are limited. Therapeutic hypothermia improves outcome after cardiac arrest, is strongly neuroprotective in experimental stroke, and is under clinical trial in stroke. Hypothermia lowers elevated intracranial pressure; however, rebound intracranial pressure elevation and neurological deterioration may occur during rewarming. (1) Intracranial pressure increases 24 h after moderate and small strokes. (2) Short-duration hypothermia-rewarming, instituted before intracranial pressure elevation, prevents this 24 h intracranial pressure elevation. Long-Evans rats with two hour middle cerebral artery occlusion or outbred Wistar rats with three hour middle cerebral artery occlusion had intracranial pressure measured at baseline and 24 h. Wistars were randomized to 2·5 h hypothermia (32·5°C) or normothermia, commencing 1 h after stroke. In Long-Evans rats (n = 5), intracranial pressure increased from 10·9 ± 4·6 mmHg at baseline to 32·4 ± 11·4 mmHg at 24 h, infarct volume was 84·3 ± 15·9 mm(3) . In normothermic Wistars (n = 10), intracranial pressure increased from 6·7 ± 2·3 mmHg to 31·6 ± 9·3 mmHg, infarct volume was 31·3 ± 18·4 mm(3) . In hypothermia-treated Wistars (n = 10), 24 h intracranial pressure did not increase (7·0 ± 2·8 mmHg, P intracranial pressure elevation 24 h after stroke in two rat strains, even after small strokes. Short-duration hypothermia prevented the intracranial pressure rise, an effect sustained for at least 18 h after rewarming. The findings have potentially important implications for design of future clinical trials. © 2013 The Authors. International Journal of Stroke © 2013 World Stroke Organization.

    Sexual violence continues to be a significant public health problem worldwide with serious consequences for individuals and communities. The implementation of prevention strategies that address risk and protective factors for sexual violence at the community level are important components of a comprehensive approach, but few such strategies have been identified or evaluated. The current review explores one potential opportunity for preventing sexual violence perpetration at the community level: alcohol policy. Alcohol policy has the potential to impact sexual violence perpetration through the direct effects of excessive alcohol consumption on behavior or through the impact of alcohol and alcohol outlets on social organization within communities. Policies affecting alcohol pricing, sale time, outlet density, drinking environment, marketing, and college environment are reviewed to identify existing evidence of impact on rates of sexual violence or related outcomes, including risk factors and related health behaviors. Several policy areas with initial evidence of an association with sexual violence outcomes were identified, including policies affecting alcohol pricing, alcohol outlet density, barroom management, sexist content in alcohol marketing, and policies banning alcohol on campus and in substance-free dorms. We identify other policy areas with evidence of an impact on related outcomes and risk factors that may also hold potential as a preventative approach for sexual violence perpetration. Evidence from the current review suggests that alcohol policy may represent one promising avenue for the prevention of sexual violence perpetration at the community level, but additional research is needed to directly examine effects on sexual violence outcomes.

    Objective: To analyse the impact of the alcohol market on the implementation of strong-willed public alcohol abuse prevention policies based on a critical review of the literature. Method: Documentary research and analysis of the alcohol market economic data were performed. An overview of public alcohol abuse prevention policies was conducted from a historical perspective by distinguishing drunkenness control policies, protection of vulnerable populations, and the fight against drink driving and drinking in the workplace. Results: Public alcohol abuse prevention policies are primarily designed to reduce the harmful consequences of alcohol occurring as a result of a drinking episode (motor vehicle accident, highway accidents, etc.), while neglecting the long-term consequences (cancer, cirrhosis, etc.). Moreover, while taxation is one of the major public health tools used to reduce the costs of alcohol-related damage on society, the State exercises legislative and tax protection for alcoholic beverages produced in France. In particular, wine benefits from a lower tax rate than other stronger forms of alcohol (spirits, liquors, etc.). The economic weight of the alcohol market can provide an explanation for these public alcohol abuse prevention policies. Conclusion: In view of the mortality caused by alcohol abuse, France must implement a proactive public policy. An alcohol taxation policy based on the alcohol content, a minimum unit pricing for alcohol, or higher taxes on alcohol are public policies that could be considered in order to reduce alcohol-related mortality.

    The most frequent cardiac arrhythmia and main cause for cardio-embolic stroke is atrial fibrillation. Prophylaxis for thrombembolic events is performed regarding individual risk of patients with either ASS or vitamin-K-antagonists. Efficacy and safety of oral anticoagulation is limited by a narrow therapeutical range as well as by inter- and intraindividual variability of INR-values due to genetic disposition, differences in alimentation, dosage errors, rare control of INR-levels and drug-interactions. New oral anticoagulants with different mechanisms of action may be a promising therapeutic option in future. This review addresses the new anticoagulants Apixaban, Rivaroxban and Dabigatranetexilat with the design and as available the results of the corresponding phase-III-trials in atrial fibrillation (ARISTOTLE, ROCKET-AF, RE-LY). © Georg Thieme Verlag KG Stuttgart · New York.

    The aims of this study were to map obesity prevention activity being implemented by government, non-government, and community-based organizations; to determine practitioner and policy-maker perceptions of the feasibility and effectiveness of a range of evidence-based obesity prevention strategies; and to determine practitioner and policy-maker perceptions of preferred settings for obesity prevention strategies. This study involved a cross-sectional survey of 304 public health practitioners and policy-makers from government, non-government, and community organizations across Victoria, Australia. Participants reported their organizations' current obesity prevention programs and policies, their own perceptions of the feasibility and effectiveness of strategies to prevent obesity and their preferred settings for obesity prevention. Thirty-nine percent had an obesity prevention policy, and 92% were implementing obesity prevention programs. The most common programs focused on education, skill-building, and increasing access to healthy eating/physical activity opportunities. School curriculum-based initiatives, social support for physical activity, and family-based programs were considered the most effective strategies, whereas curriculum-based initiatives, active after-school programs, and providing access to and information about physical activity facilities were deemed the most feasible strategies. Schools were generally perceived as the most preferred setting for obesity prevention. Many organizations had obesity prevention programs, but far fewer had obesity prevention policies. Current strategies and those considered feasible and effective are often mismatched with the empirical literature. Systems to ensure better alignment between researchers, practitioners, and policy-makers, and identifying effective methods of translating empirical evidence into practice and policy are required.

    Two decades of epidemiological research shows that silent cerebrovascular disease is common and is associated with future risk for stroke and dementia. It is the most common incidental finding on brain scans. To summarize evidence on the diagnosis and management of silent cerebrovascular disease to prevent stroke, the Stroke Council of the American Heart Association convened a writing committee to evaluate existing evidence, to discuss clinical considerations, and to offer suggestions for future research on stroke prevention in patients with 3 cardinal manifestations of silent cerebrovascular disease: silent brain infarcts, magnetic resonance imaging white matter hyperintensities of presumed vascular origin, and cerebral microbleeds. The writing committee found strong evidence that silent cerebrovascular disease is a common problem of aging and that silent brain infarcts and white matter hyperintensities are associated with future symptomatic stroke risk independently of other vascular risk factors. In patients with cerebral microbleeds, there was evidence of a modestly increased risk of symptomatic intracranial hemorrhage in patients treated with thrombolysis for acute ischemic stroke but little prospective evidence on the risk of symptomatic hemorrhage in patients on anticoagulation. There were no randomized controlled trials targeted specifically to participants with silent cerebrovascular disease to prevent stroke. Primary stroke prevention is indicated in patients with silent brain infarcts, white matter hyperintensities, or microbleeds. Adoption of standard terms and definitions for silent cerebrovascular disease, as provided by prior American Heart Association/American Stroke Association statements and by a consensus group, may facilitate diagnosis and communication of findings from radiologists to clinicians. © 2016 American Heart Association, Inc.

    Child sexual abuse affects thousands of children in the United States and is vastly underreported. Tertiary prevention policies, primarily in the form of sex offender registries and community notification programs, have received the most attention and funding. Few policies have focused on school-based prevention. One recently passed law in Illinois mandates all K-5 public schools to implement sexual abuse prevention programs. The law was championed by a young social worker, Erin Merryn. Through the multiple streams framework, this article examines the unique set of political circumstances, united with Merryn's advocacy, which created the opportunity for the law to pass.

    Heat stroke is the most severe pathology related to heat. It is defined as an increase in core body temperature accompanied by signs of neurological dysfunction. In the absence of an early treatment, it has a very high mortality rate. Topiramate is a well known drug widely used in epilepsy treatment and migraine prevention. Oligohydrosis has been described amongst topiramate side effects, favouring the risk of hyperthermia and heatstroke. We present the case of a patient who developed heat stroke due to physical exercise while under topiramate treatment. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana.

    The effect of modifiable stroke risk factors in terms of prevented cases remains unclear due to sex-specific disease rate and risk factors prevalence. Our aim was to estimate their impact on stroke by gender through population-attributable fraction (PAF), preventive fraction (PF) and their combination in EPIC-Italian cohort. 43,976 participants, age 34-75, and free of cardiovascular disease at baseline (1993-1998) were followed up for almost 11 years. Adjusted hazard ratios and PAF were estimated using Cox models. We identified 386 cases. In males, the burden for stroke was 17% (95% CI 4-28%) for smoking and 14% (95% CI 5-22%) for alcohol consumption. In females, hypertension was carrying the biggest burden with 18% (95% CI 9-26%) followed by smoking 15% (95% CI 7-22%). Their combination was 46% (95% CI 32-58%) in males and 48% (95% CI 35-59%) in females. PF for current smokers was gender unequal [males 21% (95% CI 15-27%) females 9% (95% CI 1-17%)]. Half of strokes are attributable to potentially modifiable factors. The proportion of prevented cases is gender unbalanced, encouraging sex-specific intervention.

    Full Text Available Female fertility begins to decline many years prior to the onset of menopause despite continued regular ovulatory cycles. Age related infertility is due to oocyte abnormalities and decreased ovarian reserve. Treatment of infertility when the cause is limited to decreased ovarian reserve is empirical at present except for oocyte donation. This mini review of the literature covers all available English biomedical journals that have been published from 1995 to 2008. The search based on combination of the words age, fertility, infertility, and oocyte abnormalities. The important findings from this search strategy are summarized and presented in the sub headings including female age and fertility, miscarriage and in vitro fertilization. Regarding infertility prevention, this mini review suggested that early marriage is a primordial, effective, inexpensive and easy way to prevent infertility.

    Murray, Elizabeth; Vess, Joy; Edlund, Barbara J

    2016-01-01

    Preventing patient falls begins with an accurate assessment of a patient's risk of falling followed by the initiation and continued evaluation of a fall prevention program based on patient-specific identified risks. Children have a normal tendency to fall based on developmental growth, and each child is different in physical and cognitive abilities. Falls may occur both in and out of the hospital setting. Prevention programs that have revealed the most favorable restuls include the use of a validated fall risk assessment tool. The Humpty Dumpty fall Scale is a screening tool specifically developed for pediatric patients to assess risk for fall. This project developed a pediatric fall prevention policy and implemented an inpatient pediatric fall prevention program. Pediatric staff contributed to the development of this policy and program by providing feedback, support, and cooperation, which was instrumental in the success of this program resulting in no falls after implementation.

    The impact on health of alcohol in a given society is mainly related with the volume and pattern of drinking, and these are related with individual factors, but also with environmental factors, among which public policies are important determinants. Public policies may favour or reduce alcohol use, and thus have a substantial preventive capacity. The effectiveness of policies to prevent the harm caused by alcohol has been reviewed in recent documents, which provide evidence to extract recommendations. This paper reviews the most effective policies to reduce the harm caused by alcohol, with an emphasis in the use of taxes to increase its cost, availability regulation, and policies on drinking and driving. The regulation of alcohol promotion and publicity is also assessed, as well as the detection and treatment of alcohol abuse and dependence. The state of alcohol related policies in Spain is analysed, as well as the obstacles, for the adoption of policies more prone to prevention, and recommendations for the future are made.

  7. Systems pharmacology dissection of multi-scale mechanisms of action for herbal medicines in stroke treatment and prevention.

    Directory of Open Access Journals (Sweden)

    Jingxiao Zhang

    Full Text Available Annually, tens of millions of first-ever strokes occur in the world; however, currently there is lack of effective and widely applicable pharmacological treatments for stroke patients. Herbal medicines, characterized as multi-constituent, multi-target and multi-effect, have been acknowledged with conspicuous effects in treating stroke, and attract extensive interest of researchers although the mechanism of action is yet unclear. In this work, we introduce an innovative systems-pharmacology method that combines pharmacokinetic prescreening, target fishing and network analysis to decipher the mechanisms of action of 10 herbal medicines like Salvia miltiorrhizae, Ginkgo biloba and Ephedrae herba which are efficient in stroke treatment and prevention. Our systematic analysis results display that, in these anti-stroke herbal medicines, 168 out of 1285 constituents with the favorable pharmacokinetic profiles might be implicated in stroke therapy, and the systematic use of these compounds probably acts through multiple mechanisms to synergistically benefit patients with stroke, which can roughly be classified as preventing ischemic inflammatory response, scavenging free radicals and inhibiting neuronal apoptosis against ischemic cerebral damage, as well as exhibiting lipid-lowering, anti-diabetic, anti-thrombotic and antiplatelet effects to decrease recurrent strokes. Relying on systems biology-based analysis, we speculate that herbal medicines, being characterized as the classical combination therapies, might be not only engaged in multiple mechanisms of action to synergistically improve the stroke outcomes, but also might be participated in reducing the risk factors for recurrent strokes.

    People with stroke or transient ischaemic attack (TIA) are at increased risk of future stroke and other cardiovascular events. Evidence-based strategies for secondary stroke prevention have been established. However, the implementation of prevention strategies could be improved. To assess the effects of stroke service interventions for implementing secondary stroke prevention strategies on modifiable risk factor control, including patient adherence to prescribed medications, and the occurrence of secondary cardiovascular events. We searched the Cochrane Stroke Group Trials Register (April 2013), the Cochrane Effective Practice and Organisation of Care Group Trials Register (April 2013), CENTRAL (The Cochrane Library 2013, issue 3), MEDLINE (1950 to April 2013), EMBASE (1981 to April 2013) and 10 additional databases. We located further studies by searching reference lists of articles and contacting authors of included studies. We included randomised controlled trials (RCTs) that evaluated the effects of organisational or educational and behavioural interventions (compared with usual care) on modifiable risk factor control for secondary stroke prevention. Two review authors selected studies for inclusion and independently extracted data. One review author assessed the risk of bias for the included studies. We sought missing data from trialists. This review included 26 studies involving 8021 participants. Overall the studies were of reasonable quality, but one study was considered at high risk of bias. Fifteen studies evaluated predominantly organisational interventions and 11 studies evaluated educational and behavioural interventions for patients. Results were pooled where appropriate, although some clinical and methodological heterogeneity was present. The estimated effects of organisational interventions were compatible with improvements and no differences in the modifiable risk factors mean systolic blood pressure (mean difference (MD) -2.57 mmHg; 95% confidence

  9. Towards Health in All Policies for Childhood Obesity Prevention

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available The childhood obesity epidemic can be best tackled by means of an integrated approach, which is enabled by integrated public health policies, or Health in All Policies. Integrated policies are developed through intersectoral collaboration between local government policy makers from health and nonhealth sectors. Such intersectoral collaboration has been proved to be difficult. In this study, we investigated which resources influence intersectoral collaboration. The behavior change wheel framework was used to categorize motivation-, capability-, and opportunity-related resources for intersectoral collaboration. In-depth interviews were held with eight officials representing 10 non-health policy sectors within a local government. Results showed that health and non-health policy sectors did not share policy goals, which decreased motivation for intersectoral collaboration. Awareness of the linkage between health and nonhealth policy sectors was limited, and management was not involved in creating such awareness, which reduced the capability for intersectoral collaboration. Insufficient organizational resources and structures reduced opportunities for intersectoral collaboration. To stimulate intersectoral collaboration to prevent childhood obesity, we recommend that public health professionals should reframe health goals in the terminology of nonhealth policy sectors, that municipal department managers should increase awareness of public health in non-health policy sectors, and that flatter organizational structures should be established.

    To date, stroke prevention in patients with diabetes mellitus (DM) has been based on the control of other risk factors and comorbidities, as clinical trials aimed at intensive glycemic control have failed to prove the existence of any sort of benefit in reducing macrovascular complications. However, thanks to the FDA's requirement to evaluate the vascular risk of antidiabetic drugs, there has been significant progress in the knowledge of their benefits on the risk of vascular death, acute myocardial infarction and non-fatal stroke in patients with type 2 DM and high vascular risk. This implies the need to incorporate these drugs into the overall vascular prevention strategy in patients with DM who have already suffered a stroke. This manuscript is a critical, non-systematic review on the oral antidiabetics that have demonstrated any sort of effect on stroke risk, interpreting the results of the main clinical trials from the neurologist's point of view.

    Full Text Available Post-stroke depression (PSD is a common neuropsychiatric complication of stroke. However, due to the high expense and side effects of pharmacotherapy and the difficult-to-achieve of psychotherapy, the prevention and treatment of PSD are still far from satisfaction. Inflammation hypothesis is now playing an essential role in the pathophysiological mechanism of PSD, and it may be a new preventive and therapeutic target. Remote ischemic conditioning (RIC is a non-invasive and easy-to-use physical strategy, which has been used to protect brain (including ischemic and hemorrhagic stroke, heart and many other organs in clinical trials. The underlying mechanisms of RIC include anti-inflammation, anti-oxidative stress, immune system regulation and other potential pathways. Our hypothesis is that RIC is a novel approach to prevent PSD. The important implications of this hypothesis are that: (1 RIC could be widely used in clinical practice to prevent PSD if our hypothesis were verified; and (2 RIC would be thoroughly explored to test its effects on other neurobehavioral disorders (e.g., cognitive impairment.

    This study examined the efficacy of antidepressant treatment for preventing the onset of generalized anxiety disorder (GAD) among patients with recent stroke. Of 799 patients assessed, 176 were randomized, and 149 patients without evidence of GAD at the initial visit were included in this double-blind treatment with escitalopram (N=47) or placebo (N=49) or non-blinded problem-solving therapy (PST; 12 total sessions; N=53). Participants given placebo over 12 months were 4.95 times more likely to develop GAD than patients given escitalopram and 4.00 times more likely to develop GAD than patients given PST. Although these results should be considered preliminary, the authors found that both escitalopram and PST were effective in preventing new onset of post-stroke GAD.

    Full Text Available Supplementation with B vitamins for stroke prevention has been evaluated over the years, but which combination of B vitamins is optimal for stroke prevention is unclear. We performed a network meta-analysis to assess the impact of different combinations of B vitamins on risk of stroke.A total of 17 trials (86 393 patients comparing 7 treatment strategies and placebo were included. A network meta-analysis combined all available direct and indirect treatment comparisons to evaluate the efficacy of B vitamin supplementation for all interventions.B vitamin supplementation was associated with reduced risk of stroke and cerebral hemorrhage. The risk of stroke was lower with folic acid plus vitamin B6 as compared with folic acid plus vitamin B12 and was lower with folic acid plus vitamin B6 plus vitamin B12 as compared with placebo or folic acid plus vitamin B12. The treatments ranked in order of efficacy for stroke, from higher to lower, were folic acid plus vitamin B6 > folic acid > folic acid plus vitamin B6 plus vitamin B12 > vitamin B6 plus vitamin B12 > niacin > vitamin B6 > placebo > folic acid plus vitamin B12.B vitamin supplementation was associated with reduced risk of stroke; different B vitamins and their combined treatments had different efficacy on stroke prevention. Folic acid plus vitamin B6 might be the optimal therapy for stroke prevention. Folic acid and vitamin B6 were both valuable for stroke prevention. The efficacy of vitamin B12 remains to be studied.

  17. Metabolic vitamin B12 deficiency: a missed opportunity to prevent dementia and stroke.

    Spence, J David

    2016-02-01

    The purpose of this narrative review is to highlight insights into the importance and frequency of metabolic vitamin B12 (B12) deficiency, reasons why it is commonly missed, and reasons for the widespread but mistaken belief that treatment of B12 deficiency does not prevent stroke or improve cognitive function. Metabolic B12 deficiency is common, being present in 10%-40% of the population; is frequently missed; is easily treated; and contributes importantly to cognitive decline and stroke in older people. Measuring serum B12 alone is not sufficient for diagnosis; it is necessary to measure holotranscobalamin or functional markers of B12 adequacy such as methylmalonic acid or plasma total homocysteine. B-vitamin therapy with cyanocobalamin reduces the risk of stroke in patients with normal renal function but is harmful (perhaps because of thiocyanate accumulation from cyanide in cyanocobalamin) in patients with renal impairment. Methylcobalamin may be preferable in renal impairment. B12 therapy slowed gray matter atrophy and cognitive decline in the Homocysteine and B Vitamins in Cognitive Impairment Trial. Undiagnosed metabolic B12 deficiency may be an important missed opportunity for prevention of dementia and stroke; in patients with metabolic B12 deficiency, it would be prudent to offer inexpensive and nontoxic supplements of oral B12, preferably methylcobalamin or hydroxycobalamin. Future research is needed to distinguish the effects of thiocyanate from cyanocobalamin on hydrogen sulfide, and effects of treatment with methylcobalamin on cognitive function and stroke, particularly in patients with renal failure.

Vitamin K antagonists (VKA have been the standard of care for long-term OAT for decades, but non-VKA oral anticoagulants (NOAC have recently been approved for this indication, and raised many questions, among them their influence on medication adherence. We assessed adherence to VKA and NOAC in secondary stroke prevention. Methods: All patients treated from October 2011 to September 2012 for ischemic stroke or transient ischemic attack with a subsequent indication for OAT, at three academic hospitals were entered into a prospective registry, and baseline data and antithrombotic treatment at discharge were recorded. At the 1-year follow-up, we assessed the adherence to different OAT strategies and patients’ adherence to their respective OAT. We noted OAT changes, reasons to change treatment, and factors that influence persistence to the prescribed OAT. Results: In patients discharged on OAT, we achieved a fatality corrected response rate of 73.3% (n=209. A total of 92% of these patients received OAT at the 1-year follow-up. We observed good adherence to both VKA and NOAC (VKA, 80.9%; NOAC, 74.8%; P=0.243 with a statistically nonsignificant tendency toward a weaker adherence to dabigatran. Disability at 1-year follow-up was an independent predictor of lower adherence to any OAT after multivariate analysis, whereas the choice of OAT did not have a relevant influence. Conclusion: One-year adherence to OAT after stroke is strong (>90% and patients

    The vast majority of children with sickle cell anemia (SCA) live in Africa, where evidence-based guidelines for primary stroke prevention are lacking. In Kano, Nigeria, we conducted a feasibility trial to determine the acceptability of hydroxyurea therapy for primary stroke prevention in children with abnormal transcranial Doppler (TCD) measurements. Children with SCA and abnormal non-imaging TCD measurements (≥200 cm/s) received moderate fixed-dose hydroxyurea therapy (∼20 mg/kg/day). A comparison group of children with TCD measurements hydroxyurea. The comparison group consisted of initially 210 children, of which four developed abnormal TCD measurements, and were started on hydroxyurea. None of the monthly research visits were missed (n = total 603 visits). Two and 10 deaths occurred in the treatment and comparison groups, with mortality rates of 2.69 and 1.81 per 100 patient-years, respectively (P = .67). Our results provide strong evidence, for high family recruitment, retention, and adherence rates, to undertake the first randomized controlled trial with hydroxyurea therapy for primary stroke prevention in children with SCA living in Africa. © 2017 Wiley Periodicals, Inc.

    Efforts to reverse the obesity epidemic require policy, systems, and environmental (PSE) change strategies. Despite the availability of evidence-based and other promising PSE interventions, limited evidence exists on the "how-to" of transitioning them into practice. For the past 13 years, the Los Angeles County Department of Public Health has been building capacity among community residents and other stakeholders to create effective community coalitions and to implement well-designed policy strategy campaigns using an evidence-based approach to policy change, the policy adoption model (PAM). Implementing a phase-based approach to policy change, the PAM was initially used to support the passage of over 140 tobacco control and prevention policies in Los Angeles County. Following these successes, Los Angeles County Department of Public Health applied the PAM to obesity prevention, operationalizing the policy process by training community residents and other stakeholders on the use of the model. The PAM has shown to be helpful in promoting PSE change in tobacco control and obesity prevention, suggesting a local-level model potentially applicable to other fields of public health seeking sustainable, community-driven policy change.

    The epidemiological transition in Latin America toward older urban dwelling adults has led to the rise in cardiovascular risk factors and an increase in morbidity and mortality rates related to both stroke and myocardial infarction. As a result, there is an immediate need for effective actions resulting in better detection and control of cardiovascular risk factors that will ultimately reduce cardiovascular disease burden. Data from case-control studies have identified the following risk factors associated with stroke: hypertension; smoking; abdominal obesity; diet; physical activity; diabetes; alcohol intake; psychosocial factors; cardiac causes; and dyslipidemia. In addition to its high mortality, patients who survive after a stroke present quite frequently with marked physical and functional disability. Because stroke is the leading cause of death in most Latin American countries and also because it is a clearly preventable cause of death and disability, simple, affordable, and efficient strategies must be urgently implemented in Latin America.

    Full Text Available OBJECTIVES: The effects of AT1 receptor blocker, telmisartan, and the ACE inhibitor, ramipril, were tested head-to head and in combination on stroke prevention in hypertensive rats and on potential neuroprotection in acute cerebral ischemia in normotensive rats. METHODS: Prevention study: Stroke-prone spontaneously hypertensive rats (SHR-SP were subjected to high salt and randomly assigned to 4 groups: (1 untreated (NaCl, n = 24, (2 telmisartan (T; n = 27, (3 ramipril (R; n = 27 and (4 telmisartan + ramipril (T+R; n = 26. Drug doses were selected to keep blood pressure (BP at 150 mmHg in all groups. Neurological signs and stroke incidence at 50% mortality of untreated SHR-SP were investigated. Intervention study: Normotensive Wistar rats were treated s.c. 5 days prior to middle cerebral artery occlusion (MCAO for 90 min with reperfusion. Groups (n = 10 each: (1 sham, (2 vehicle (V; 0.9% NaCl, (3 T (0.5 mg/kg once daily, (4 R (0.01 mg/kg twice daily, (5 R (0.1 mg/kg twice daily or (6 T (0.5 mg/kg once daily plus R (0.01 mg/kg twice daily. Twenty-four and 48 h after MCAO, neurological outcome (NO was determined. Forty-eight h after MCAO, infarct volume by MRI, neuronal survival, inflammation factors and neurotrophin receptor (TrkB were analysed. RESULTS: Stroke incidence was reduced, survival was prolonged and neurological outcome was improved in all treated SHR-SP with no differences between treated groups. In the acute intervention study, T and T+R, but not R alone, improved NO, reduced infarct volume, inflammation (TNFα, and induced TrkB receptor and neuronal survival in comparison to V. CONCLUSIONS: T, R or T+R had similar beneficial effects on stroke incidence and NO in hypertensive rats, confirming BP reduction as determinant factor in stroke prevention. In contrast, T and T+R provided superior neuroprotection in comparison to R alone in normotensive rats with induced cerebral ischemia.

    To describe the ongoing efforts of the Connecticut Collaboration for Fall Prevention (CCFP) to move evidence regarding fall prevention into clinical practice and state policy. A university-based team developed methods of networking with existing statewide organizations to influence clinical practice and state policy. We describe steps taken that led to funding and legislation of fall prevention efforts in the state of Connecticut. We summarize CCFP's direct outreach by tabulating the educational sessions delivered and the numbers and types of clinical care providers that were trained. Community organizations that had sustained clinical practices incorporating evidence-based fall prevention were subsequently funded through mini-grants to develop innovative interventional activities. These mini-grants targeted specific subpopulations of older persons at high risk for falls. Building collaborative relationships with existing stakeholders and care providers throughout the state, CCFP continues to facilitate the integration of evidence-based fall prevention into clinical practice and state-funded policy using strategies that may be useful to others.

    This review aims to summarize the evidence of Tai Chi and qigong interventions for the primary prevention of stroke, including the effects on populations with major stroke risk factors. A systematic literature search was conducted on January 16, 2017 using the PubMed, Scopus, Cochrane Library, and CINAHL databases. Randomized controlled trials examining the efficacy of Tai Chi or qigong for stroke prevention and stroke risk factors were included. Risk of bias was assessed using the Cochrane Risk of Bias tool. Twenty-one trials with n = 1604 patients with hypertension, hyperlipidaemia, diabetes, overweight or obesity, or metabolic syndrome were included. No trials were found that examined the effects of Tai Chi/qigong on stroke incidence. Meta-analyses revealed significant, but not robust, benefits of Tai Chi/qigong over no interventions for hypertension (systolic blood pressure: -15.55 mm Hg (95% CI: -21.16; -9.95); diastolic blood pressure: -10.66 mm Hg (95% CI: -14.90, -6.43); the homeostatic model assessment (HOMA) index (-2.86%; 95% CI: -5.35, -0.38) and fasting blood glucose (-9.6 mg/dL; 95% CI: -17.28, -1.91), and for the body mass index compared with exercise controls (-1.65 kg/m; 95% CI: -3.11, -0.20). Risk of bias was unclear or high for the majority of trials and domains, and heterogeneity between trials was high. Only 6 trials adequately reported safety. No recommendation for the use of Tai Chi/qigong for the prevention of stroke can be given. Although Tai Chi and qigong show some potential more robust studies are required to provide conclusive evidence on the efficacy and safety of Tai Chi and qigong for reducing major stroke risk factors.

  8. Population health outcome models in suicide prevention policy.

    Lynch, Frances L

    2014-09-01

    Suicide is a leading cause of death in the U.S. and results in immense suffering and significant cost. Effective suicide prevention interventions could reduce this burden, but policy makers need estimates of health outcomes achieved by alternative interventions to focus implementation efforts. To illustrate the utility of health outcome models to help in achieving goals defined by the National Action Alliance for Suicide Prevention's Research Prioritization Task Force. The approach is illustrated specifically with psychotherapeutic interventions to prevent suicide reattempt in emergency department settings. A health outcome model using decision analysis with secondary data was applied to estimate suicide attempts and deaths averted from evidence-based interventions. Under optimal conditions, the model estimated that over 1 year, implementing evidence-based psychotherapeutic interventions in emergency departments could decrease the number of suicide attempts by 18,737, and if offered over 5 years, it could avert 109,306 attempts. Over 1 year, the model estimated 2,498 fewer deaths from suicide, and over 5 years, about 13,928 fewer suicide deaths. Health outcome models could aid in suicide prevention policy by helping focus implementation efforts. Further research developing more sophisticated models of the impact of suicide prevention interventions that include a more complex understanding of suicidal behavior, longer time frames, and inclusion of additional outcomes that capture the full benefits and costs of interventions would be helpful next steps.

    Individuals with stroke fall frequently, and no exercise intervention has been shown to prevent falls post stroke. Perturbation-based balance training (PBT), which involves practicing reactions to instability, shows promise for preventing falls in older adults and individuals with Parkinson's disease. This study aimed to determine if PBT during inpatient stroke rehabilitation can prevent falls after discharge into the community. Individuals with subacute stroke completed PBT as part of routine inpatient rehabilitation (n = 31). Participants reported falls experienced in daily life for up to 6 months post discharge. Fall rates were compared to a matched historical control group (HIS) who did not complete PBT during inpatient rehabilitation. Five of 31 PBT participants, compared to 15 of 31 HIS participants, reported at least 1 fall. PBT participants reported 10 falls (.84 falls per person per year) whereas HIS participants reported 31 falls (2.0 falls per person per year). When controlled for follow-up duration and motor impairment, fall rates were lower in the PBT group than the HIS group (rate ratio: .36 [.15, .79]; P = .016). These findings suggest that PBT is promising for reducing falls post stroke. While this was not a randomized controlled trial, this study may provide sufficient evidence for implementing PBT in stroke rehabilitation practice. Copyright © 2017 National Stroke Association.

    Secondary prevention in ischaemic stroke and transient ischaemic attack (TIA) is dominated by pharmacological interventions with evidence for non-pharmacological interventions being less robust. This systematic review and meta-analysis examines the impact of lifestyle interventions on secondary prevention in stroke or TIA. A systematic literature search was performed. Randomised controlled trials (RCTs) examining the effectiveness of intervention packages incorporating any key component of health education/promotion/counselling on lifestyle and/or aerobic exercise compared to usual care ± a sham intervention in participants with ischaemic stroke or TIA were included. Outcomes of interest were mortality, cardiovascular disease (CVD) event rates, cardiovascular risk factors including blood pressure, lipid profiles and physical activity participation. Methodological quality was assessed. Statistical analyses determining treatment effect were conducted using Cochrane Review Manager Software. Seventeen RCTs were included. Data pooled from eight studies with a total of 2478 patients, demonstrated no effect in favour of lifestyle interventions compared to routine or sham interventions on mortality (risk ratio (RR) = 1.13 (95% confidence interval (CI), 0.85-1.52), I(2) = 0%). Data relating to CVD events were pooled from four studies (1013 patients), demonstrated non-significant findings (RR = 1.16 (95% CI, 0.80--1.71), I(2) = 0%). Similar results were reported for total cholesterol. Physical activity participation demonstrated significant improvement [SMD 0.24 (95% CI, 0.08-0.41), l (2) = 47%]. Blood pressure reductions were noted but were non-significant when corrected for multimodal packages including enhanced pharmacotherapy compliance. There is currently insufficient high quality research to support lifestyle interventions post-stroke or TIA on mortality, CVD event rates and cardio-metabolic risk factor profiles. Promising blood pressure reductions were noted in

  13. Calcium-channel blockers for the prevention of stroke: from scientific evidences to the clinical practice

    2013-05-01

    Full Text Available AIM OF THE REVIEW The present review aims to analyze the role of calcium-channel blockers, and particularly newer molecules, as first-line therapy for cerebrovascular disease. BACKGROUND Stroke is the leading cause of disability in the general population. Among traditional cardiovascular risk factors, hypertension has a key role in the genesis of both hemorrhagic and ischemic stroke and a direct correlation exists between blood pressure values and the risk of stroke. Moreover, blood pressure reduction has been demonstrated to be the most important route to reduce stroke incidence and recurrence. However, the mere reduction of blood pressure values does not normalize the cardiovascular risk of the hypertensive patient. It is therefore necessary to use drug classes that beyond their blood pressure-lowering effect have also an additional effect in terms of organ protection. Among these, calcium-channel blockers have a crucial profile. Firstly, they are effective in inducing left ventricular hypertrophy regression, with a strength at least equal to that of ACE-inhibitors. Secondly, they have an antithrombotic and an endothelium-protecting effect, mediated by their antioxidant activity. Finally, calcium-channel blockers are the most powerful drugs in preventing vascular remodeling. For these reasons this drug class has probably the strongest antiatherosclerotic effect, and it is the first-choice treatment mainly for cerebrovascular disease. Among different available calcium-channel blockers, the newer ones seem to possess pharmacokinetic characteristics allowing a more homogeneous 24 hours coverage as compared to older molecules, and preliminary data seem to suggest a greater beneficial effect also on left ventricular hypertrophy and lower incidence of side effects. CONCLUSIONS Although blood pressure reduction is the main tool to reduce cerebrovascular risk in hypertensive patients, some drug classes, such as calciumchannel blockers, seem to provide

    Full Text Available Abstract Background Suboptimal uptake of anticoagulation for stroke prevention in atrial fibrillation has persisted for over 20 years, despite high-level evidence demonstrating its effectiveness in reducing the risk of fatal and disabling stroke. Methods The STOP STROKE in AF study is a national, cluster randomised controlled trial designed to improve the uptake of anticoagulation in primary care. General practitioners from around Australia enrolling in this ‘distance education’ program are mailed written educational materials, followed by an academic detailing session delivered via telephone by a medical peer, during which participants discuss patient de-identified cases. General practitioners are then randomised to receive written specialist feedback about the patient de-identified cases either before or after completing a three-month posttest audit. Specialist feedback is designed to provide participants with support and confidence to prescribe anticoagulation. The primary outcome is the proportion of patients with atrial fibrillation receiving oral anticoagulation at the time of the posttest audit. Discussion The STOP STROKE in AF study aims to evaluate a feasible intervention via distance education to prevent avoidable stroke due to atrial fibrillation. It provides a systematic test of augmenting academic detailing with expert feedback about patient management.

    Background Sickle cell disease is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. Sickle cell disease can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Stroke affects around 10% of children with sickle cell anaemia (HbSS). Chronic blood transfusions may reduce the risk of vaso-occlusion and stroke by diluting the proportion of sickled cells in the circulation. This is an update of a Cochrane Review first published in 2002, and last updated in 2013. Objectives To assess risks and benefits of chronic blood transfusion regimens in people with sickle cell disease for primary and secondary stroke prevention (excluding silent cerebral infarcts). Search methods We searched for relevant trials in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Transfusion Evidence Library (from 1980), and ongoing trial databases; all searches current to 04 April 2016. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register: 25 April 2016. Selection criteria Randomised controlled trials comparing red blood cell transfusions as prophylaxis for stroke in people with sickle cell disease to alternative or standard treatment. There were no restrictions by outcomes examined, language or publication status. Data collection and analysis Two authors independently assessed trial eligibility and the risk of bias and extracted data. Main results We included five trials (660 participants) published between 1998 and 2016. Four of these trials were terminated early. The vast majority of participants had the haemoglobin (Hb)SS form of sickle cell disease. Three trials compared regular red cell transfusions to standard care in primary prevention of stroke: two in children with no previous long-term transfusions; and one in children and adolescents on long-term transfusion. Two trials compared the drug

    2013-01-01

    To estimate the cost-effectiveness and cost-utility of dabigatran in the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation in Portugal. A Markov model was used to simulate patients' clinical course, estimating the occurrence of ischemic and hemorrhagic stroke, transient ischemic attack, systemic embolism, myocardial infarction, and intra- and extracranial hemorrhage. The clinical parameters are based on the results of the RE-LY trial, which compared dabigatran with warfarin, and on a meta-analysis that estimated the risk of each event in patients treated with aspirin or with no antithrombotic therapy. Dabigatran provides an increase of 0.331 life years and 0.354 quality-adjusted life years for each patient. From a societal perspective, these clinical gains entail an additional expenditure of 2978 euros. Thus, the incremental cost is 9006 euros per life year gained and 8409 euros per quality-adjusted life year. The results show that dabigatran reduces the number of events, especially the most severe such as ischemic and hemorrhagic stroke, as well as their long-term sequelae. The expense of dabigatran is partially offset by lower event-related costs and by the fact that INR monitoring is unnecessary. It can thus be concluded that the use of dabigatran in clinical practice in Portugal is cost-effective. Copyright © 2013 Sociedade Portuguesa de Cardiologia. Published by Elsevier España.

    Aycock, Dawn M; Clark, Patricia C

    2015-01-01

    African Americans are at heightened risk of first stroke, and regular exercise can reduce stroke risk. Benefits and barriers to exercise subscales from 2 instruments were combined to create the Exercise Benefits and Barriers for Stroke Prevention (EBBSP) scale. Reliability and validity of the EBBSP scale were examined in a nonrandom sample of 66 African Americans who were primarily female, average age 43.3 ± 9.4 years, and high school graduates. Both subscales had adequate internal consistency reliability. Factor analysis revealed two factors for each subscale. More benefits and fewer perceived barriers were significantly related to current exercise and future intentions to exercise. The EBBSP scale may be useful in research focused on understanding, predicting, and promoting exercise for stroke prevention in adults.

    Currently available data do not provide definitive evidence on the comparative benefits of closure of patent foramen ovale, oral anticoagulants and antiplatelet therapy in patients with patent foramen ovale-associated cryptogenic stroke To assess whether transcatheter patent foramen ovale closure plus antiplatelet therapy is superior to antiplatelet therapy alone and whether oral anticoagulant therapy is superior to antiplatelet therapy, for secondary stroke prevention in patients aged 16 to 60 years with a large patent foramen ovale or a patent foramen ovale associated with an atrial septal aneurysm, and an otherwise unexplained ischaemic stroke or retinal ischaemia. Six hundred and sixty-four patients were included in the study. CLOSE is an academic-driven, multicentre, randomized, open-label, three-group, superiority trial with blinded adjudication of outcome events. The trial has been registered with Clinical Trials Register (Clinicaltrials.gov, NCT00562289). Patient recruitment started in December 2007. Patient follow-up will continue until December 2016. Expected mean follow-up = 5.6 years. The primary efficacy outcome is the occurrence of fatal or nonfatal stroke. Safety outcomes include fatal, life-threatening or major procedure- or device-related complications and fatal, life-threatening or major haemorrhagic complications. CLOSE is the first specifically designed trial to assess the superiority of patent foramen ovale closure over antiplatelet therapy alone and the superiority of oral anticoagulants over antiplatelet therapy to prevent stroke recurrence in patients with patent foramen ovale-associated cryptogenic stroke. © 2016 World Stroke Organization.

    The aim of this study was to evaluate whether the remote introduction of electronic decision support tools into family practices improves risk factor control after first stroke. This study also aimed to develop methods to implement cluster randomized trials in stroke using electronic health records. Family practices were recruited from the UK Clinical Practice Research Datalink and allocated to intervention and control trial arms by minimization. Remotely installed, electronic decision support tools promoted intensified secondary prevention for 12 months with last measure of systolic blood pressure as the primary outcome. Outcome data from electronic health records were analyzed using marginal models. There were 106 Clinical Practice Research Datalink family practices allocated (intervention, 53; control, 53), with 11 391 (control, 5516; intervention, 5875) participants with acute stroke ever diagnosed. Participants at trial practices had similar characteristics as 47,887 patients with stroke at nontrial practices. During the intervention period, blood pressure values were recorded in the electronic health records for 90% and cholesterol values for 84% of participants. After intervention, the latest mean systolic blood pressure was 131.7 (SD, 16.8) mm Hg in the control trial arm and 131.4 (16.7) mm Hg in the intervention trial arm, and adjusted mean difference was -0.56 mm Hg (95% confidence interval, -1.38 to 0.26; P=0.183). The financial cost of the trial was approximately US $22 per participant, or US $2400 per family practice allocated. Large pragmatic intervention studies may be implemented at low cost by using electronic health records. The intervention used in this trial was not found to be effective, and further research is needed to develop more effective intervention strategies. http://www.controlled-trials.com.

    2014-01-01

    By 2002, China’s prevalence of overweight and obesity among adults was 18.9 percent and 2.9 percent, respectively. The Chinese traditional diet has been replaced by the “Western diet” and major declines in all phases of activity and increased sedentary activity as the main reasons explaining the rapid increase in overweight and obesity, bring major economic and health costs. The Nutrition Improvement Work Management Approach was released in 2010. Overweight and obesity prevention-related policies were added to national planning for disease prevention and control. The Guidelines for Prevention and Control of Overweight and Obesity of Chinese Adults and the School-age Children and Teenagers Overweight and Obesity Prevention and Control Guidelines in China were promulgated in 2003 and 2007, respectively. Few education programs have been implemented. Selected academic intervention research projects dominate with a focus on reducing child obesity and promoting healthier diets; increasing physical activity and reducing sedentary time; and facilitating changes in family, school, social, and cultural environments. Intervention samples are small and have not addressed the increasing rates of obesity throughout the entire population. Government provision of effective policy measures, multisectoral cooperation and increasing corporate social responsibility are keys to curb the trend toward overweight and obesity in China.

    The rate of adolescent suicide has increased dramatically in the past few decades, prompting several interventions to curb the increase. Unfortunately, many of the intervention efforts have not benefited from current research findings because the communication between researchers and those who develop the interventions is inadequate. Of specific concern are the increasingly popular curriculum-based suicide prevention programs, which have not demonstrated effectiveness and may contain potentially deleterious components. This article reviews the current epidemiological research in adolescent suicide and suggests how this knowledge could be used more effectively to reduce the rate of adolescent suicide. Recommendations include support for integrated primary prevention efforts; suicide prevention education for professionals; education and policies on firearm management; education for the media about adolescent suicide; more efficient identification and treatment of at-risk youth, including those exposed to suicidal behavior; crisis intervention; and treatment for suicide attempters.

    Full Text Available Effective methods of secondary prevention after stroke or TIA are available but adherence to recommended evidence-based treatments is often poor. The study aimed to determine the quality of secondary prevention in usual care and to develop a stepwise modeled support program.Two consecutive cohorts of patients with acute minor stroke or TIA undergoing usual outpatient care versus a secondary prevention program were compared. Risk factor control and medication adherence were assessed in 6-month follow-ups (6M-FU. Usual care consisted of detailed information concerning vascular risk factor targets given at discharge and regular outpatient care by primary care physicians. The stepwise modeled support program additionally employed up to four outpatient appointments. A combination of educational and behavioral strategies was employed.168 patients in the observational cohort who stated their openness to participate in a prevention program (mean age 64.7 y, admission blood pressure (BP: 155/84 mmHg and 173 patients participating in the support program (mean age 67.6 y, BP: 161/84 mmHg were assessed at 6 months. Proportions of patients with BP according to guidelines were 50% in usual-care and 77% in the support program (p<0.01. LDL<100 mg/dl was measured in 62 versus 71% (p = 0.12. Proportions of patients who stopped smoking were 50 versus 79% (p<0.01. 72 versus 89% of patients with atrial fibrillation were on oral anticoagulation (p = 0.09.Risk factor control remains unsatisfactory in usual care. Targets of secondary prevention were met more often within the supported cohort. Effects on (cerebro-vascular recurrence rates are going to be assessed in a multicenter randomized trial.

  5. Obesity prevention: the role of policies, laws and regulations.

    The commercial drivers of the obesity epidemic are so influential that obesity can be considered a robust sign of commercial success - consumers are buying more food, more cars and more energy-saving machines. It is unlikely that these powerful economic forces will change sufficiently in response to consumer desires to eat less and move more or corporate desires to be more socially responsible. When the free market creates substantial population detriments and health inequalities, government policies are needed to change the ground rules in favour of population benefits.Concerted action is needed from governments in four broad areas: provide leadership to set the agenda and show the way; advocate for a multi-sector response and establish the mechanisms for all sectors to engage and enhance action; develop and implement policies (including laws and regulations) to create healthier food and activity environments, and; secure increased and continued funding to reduce obesogenic environments and promote healthy eating and physical activity.Policies, laws and regulations are often needed to drive the environmental and social changes that, eventually, will have a sustainable impact on reducing obesity. An 'obesity impact assessment' on legislation such as public liability, urban planning, transport, food safety, agriculture, and trade may identify 'rules' which contribute to obesogenic environments. In other areas, such as marketing to children, school food, and taxes/levies, there may be opportunities for regulations to actively support obesity prevention. Legislation in other areas such as to reduce climate change may also contribute to obesity prevention ('stealth interventions'). A political willingness to use policy instruments to drive change will probably be an early hallmark of successful obesity prevention.

    This paper is aimed at critically assessing the extent to which Non-Communicable Disease NCD-related policies introduced in Bangladesh align with the World Health Organization's (WHO) 2013-2020 Action Plan for the Global Strategy for the Prevention and Control of NCDs. The authors reviewed all relevant policy documents introduced by the Government of Bangladesh since its independence in 1971. The literature review targeted scientific and grey literature documents involving internet-based search, and expert consultation and snowballing to identify relevant policy documents. Information was extracted from the documents using a specific matrix, mapping each document against the six objectives of the WHO 2013-2020 Action Plan for the Global Strategy for the Prevention and Control of NCDs. A total of 51 documents were identified. Seven (14%) were research and/or surveys, nine were on established policies (17%), while seventeen (33%) were on action programmes. Five (10%) were related to guidelines and thirteen (25%) were strategic planning documents from government and non-government agencies/institutes. The study covered documents produced by the Government of Bangladesh as well as those by quasi-government and non-government organizations irrespective of the extent to which the intended policies were implemented. The policy analysis findings suggest that although the government has initiated many NCD-related policies or programs, they lacked proper planning, implementation and monitoring. Consequently, Bangladesh over the years had little success in effectively addressing the growing burden of non-communicable diseases. It is imperative that future research critically assess the effectiveness of national NCD policies by monitoring their implementation and level of population coverage.

    Cerebrovascular benefits using the 23-valent pneumococcal polysaccharide vaccine (PPV23) are controversial. This study assessed clinical effectiveness of PPV23 in preventing ischemic stroke in people older than 60 years. We conducted a population-based cohort study involving 27,204 individuals of 60 years or older in Tarragona, Spain, who were prospectively followed from December 01, 2008, until November 30, 2011. Outcomes were neuroimaging-confirmed ischemic stroke, 30-day mortality from stroke, and all-cause death. Pneumococcal vaccination effectiveness was evaluated by Cox regression analyses, estimating hazard ratios (HRs) adjusted for age, sex, comorbidities, and influenza vaccine status. Cohort members were followed for a total of 76,033 person-years, of which 29,065 were for vaccinated subjects. Overall, 343 cases of stroke, 45 deaths from stroke, and 2465 all-cause deaths were observed. Pneumococcal vaccination did not alter the risk of stroke (multivariable HR: 1.04; 95% confidence interval [CI]: .83-1.30; P=.752), death from stroke (HR: 1.14; 95% CI: .61-2.13; P=.686), and all-cause death (HR: .97; 95% CI: .89-1.05; P=.448). In analyses focused on people with and without a history of cerebrovascular disease, the PPV23 did not emerge effective in preventing any analyzed event, but influenza vaccine emerged independently associated with a reduced risk of death from stroke (HR: .51; 95% CI: .28-.93; P=.029) and all-cause death (HR: .73; 95% CI: .67-.81; Pvaccine in reducing specific- and all-cause mortality risk in the general population older than 60 years.

    We aimed to examine whether the efficacy of folic acid therapy in the primary prevention of stroke is jointly affected by smoking status and baseline folate levels in a male population in a post hoc analysis of the CSPPT (China Stroke Primary Prevention Trial). Eligible participants of the CSPPT were randomly assigned to a double-blind daily treatment of a combined enalapril 10-mg and folic acid 0.8-mg tablet or an enalapril 10-mg tablet alone. In total, 8384 male participants of the CSPPT were included in the current analyses. The primary outcome was first stroke. The median treatment duration was 4.5 years. In the enalapril-alone group, the first stroke risk varied by baseline folate levels and smoking status (never versus ever). Specifically, there was an inverse association between folate levels and first stroke in never smokers ( P for linear trend=0.043). However, no such association was found in ever smokers. A test for interaction between baseline folate levels and smoking status on first stroke was significant ( P =0.045). In the total sample, folic acid therapy significantly reduced the risk of first stroke in never smokers with folate deficiency (hazard risk, 0.36; 95% confidence interval, 0.16-0.83) and in ever smokers with normal folate levels (hazard risk, 0.69; 95% confidence interval, 0.48-0.99). Baseline folate levels and smoking status can interactively affect the risk of first stroke. Our data suggest that compared with never smokers, ever smokers may require a higher dosage of folic acid to achieve a greater beneficial effect on stroke. Our findings need to be confirmed by future randomized trials. URL: https://www.clinicaltrials.gov. Unique identifier: NCT00794885. © 2017 American Heart Association, Inc.

    Doppler ultrasound (DUS) is used as a screening tool to assess internal carotid artery (ICA) disease. Recent reports suggest that the DUS may be inaccurate in over 28% of patients. We sought to evaluate the accuracy of DUS, when performed in a dedicated stroke prevention clinic (SPC). We retrospectively reviewed the charts of patients who had a DUS performed in our SPC, followed by conventional cerebral angiography. Three groups of patients were defined. Group 1 had DUS measured ICA stenosis of >50%; Group II had a DUS measured ICA stenosis of 50%--a misclassification rate of 0%. Group III consisted of five patients in whom DUS showed complete ICA occlusion. The angiogram confirmed the occlusion in all five patients--a misclassification rate of 0%. Overall, misclassification rate was 1.45% (95% CI: 0 - 4.3%). Doppler ultrasound when performed in a stroke prevention clinic (SPC), has a high accuracy in measuring ICA stenosis of >50%. Doppler ultrasound is reliable in detecting complete ICA occlusion and finally DUS is a reliable screening tool to rule out clinically significant ICA stenosis.

    Packaging waste is a major issue in several countries. Representing in industrialized countries around 30-35% of municipal solid waste yearly generated, this waste stream has steadily grown over the years even if, especially in Europe, specific recycling and recovery targets have been fixed. Therefore, an increasing attention starts to be devoted to prevention measures and interventions. Filling a gap in the current literature, this explorative paper is a first attempt to map the increasingly important phenomenon of prevention policies in the packaging sector. Through a theoretical sampling, 11 countries/states (7 in and 4 outside Europe) have been selected and analyzed by gathering and studying primary and secondary data. Results show evidence of three specific trends in packaging waste prevention policies: fostering the adoption of measures directed at improving packaging design and production through an extensive use of the life cycle assessment; raising the awareness of final consumers by increasing the accountability of firms; promoting collaborative efforts along the packaging supply chains.

    Full Text Available Background. Stroke is a major healthcare problem with serious long-term disability and is one of the leading causes of death in the world. Prevention of stroke is considered an important strategy. Methods. Seven electronic databases were searched. Results. 36 eligible studies with a total of 2393 participants were identified. Primary outcome measures, TCC exercise combined with other intervention had a significant effect on decreasing the incidence of nonfatal stroke (n=185, RR = 0.11, 95% CI 0.01 to 0.85, P=0.03 and CCD (n=125, RR = 0.33, 95% CI 0.11 to 0.96, P=0.04. For the risk factors of stroke, pooled analysis demonstrated that TCC exercise was associated with lower body weight, BMI, FBG level, and decreasing SBP, DBP, plasma TC, and LDL-C level regardless of the intervention period less than half a year or more than one year and significantly raised HDL-C level in comparison to nonintervention. Compared with other treatments, TCC intervention on the basis of the same other treatments in patients with chronic disease also showed the beneficial effect on lowering blood pressure. Conclusion. The present systematic review indicates that TCC exercise is beneficially associated with the primary prevention of stroke in middle-aged and elderly adults by inversing the high risk factors of stroke.

    There is an inflammatory component in the pathogenesis of ischaemic stroke, which plays an important role in inducing atherothrombotic and embolic stroke. Statins, HMG-CoA (3-hydroxy-3-methyl-glutaryl-coenzyme A) reductase inhibitors are widely used in the primary and secondary prevention of ischaemic stroke. It has been proved that beyond their main effect on inhibition of endogenous cholesterol, they also modify the inflammatory process. Additional benefits from the use of statins result from their effect on the immune system. Increased risk of recurrent vascular episodes and risk of death after statin withdrawal in patients with vascular disorders is connected with termination of the anti-inflammatory effect of these drugs. The authors highlight that because of the anti-inflammatory effect of statins it is reasonable to use them in all patients at risk of ischaemic stroke, including those with atrial fibrillation.

  18. Intracranial Pressure Elevation 24 Hours after Ischemic Stroke in Aged Rats is Prevented by Early, Short Hypothermia Treatment

    Lucy Anne Murtha

    2016-05-01

    Full Text Available Stroke is predominantly a senescent disease, yet most preclinical studies investigate treatment in young animals. We recently demonstrated that short-duration hypothermia-treatment completely prevented the dramatic intracranial pressure (ICP rise seen post-stroke in young rats. Here, our aim was to investigate whether a similar ICP rise occurs in aged rats and to determine whether short-duration hypothermia is an effective treatment in aged animals. Experimental Middle Cerebral Artery occlusion (MCAo - 3 hour occlusion was performed on male Wistar rats aged 19-20 months. At one hour after stroke-onset, rats were randomized to 2.5 hours hypothermia-treatment (32.5 °C or normothermia (37 °C. ICP was monitored at baseline, for 3.5 hours post-occlusion, and at 24 hours post-stroke. Infarct and edema volumes were calculated from histology. Baseline pre-stroke ICP was 11.2 ± 3.3 mmHg across all animals. Twenty-four hours post-stroke, ICP was significantly higher in normothermic animals compared to hypothermia-treated animals (27.4 ± 18.2 mmHg vs. 8.0 ± 5.0 mmHg, p = 0.03. Infarct and edema volumes were not significantly different between groups. These data demonstrate ICP may also increase 24 hours post-stroke in aged rats, and that short-duration hypothermia treatment has a profound and sustained preventative effect. These findings may have important implications for the use of hypothermia in clinical trials of aged stroke patients.

    To summarize the available evidence on the issues in health economics related to oral anticoagulation for stroke prevention in atrial fibrillation (AF) in the US. A literature review was performed using PubMed, EMBASE, Cochrane Library, and International Pharmaceutical Abstracts, as well as the websites of professional organizations. The search was conducted according to a prespecified protocol, limiting articles to those published in English from 2001 to October 2012 and focused on the economics associated with AF and AF-related stroke in the US. Data from 27 studies were extracted and included in the review. Strokes in patients with AF are more debilitating and have higher recurrence rates and mortality compared with strokes unrelated to AF. However, data describing the long-term cost of AF-related stroke and stroke subtypes remain limited. The costs of major gastrointestinal (GI) bleeding and intracranial bleeding related to warfarin are significant, whereas the costs of the more frequent minor GI bleeding are relatively low. Overall, the cost-effectiveness of warfarin versus aspirin or no treatment in patients with at least 1 risk factor for stroke is well established. Economic evaluations based on results from randomized controlled clinical trials generally found that new anticoagulants were a cost-effective alternative to warfarin for stroke prevention in AF. However, these cost-effectiveness results are highly sensitive to how well optimal international normalized ratio control is maintained (within target of 2.0-3.0) for warfarin and the time horizon used for analysis. Time in therapeutic range for warfarin in routine clinical practice was lower than in clinical trials, as shown by previous studies. This review identified several areas of uncertainty regarding the economic benefit of anticoagulants. The generalizability of cost-effectiveness results of anticoagulant therapy in AF based on clinical trial data must be confirmed by comparative effectiveness

    2009-07-01

    Full Text Available Abstract Background Stroke is the most common disabling neurological condition in adults. Falls and poor mobility are major contributors to stroke-related disability. Falls are more frequent and more likely to result in injury among stroke survivors than among the general older population. Currently there is good evidence that exercise can enhance mobility after stroke, yet ongoing exercise programs for general community-based stroke survivors are not routinely available. This randomised controlled trial will investigate whether exercise can reduce fall rates and increase mobility and physical activity levels in stroke survivors. Methods and design Three hundred and fifty community dwelling stroke survivors will be recruited. Participants will have no medical contradictions to exercise and be cognitively and physically able to complete the assessments and exercise program. After the completion of the pre-test assessment, participants will be randomly allocated to one of two intervention groups. Both intervention groups will participate in weekly group-based exercises and a home program for twelve months. In the lower limb intervention group, individualised programs of weight-bearing balance and strengthening exercises will be prescribed. The upper limb/cognition group will receive exercises aimed at management and improvement of function of the affected upper limb and cognition carried out in the seated position. The primary outcome measures will be falls (measured with 12 month calendars and mobility. Secondary outcome measures will be risk of falling, physical activity levels, community participation, quality of life, health service utilisation, upper limb function and cognition. Discussion This study aims to establish and evaluate community-based sustainable exercise programs for stroke survivors. We will determine the effects of the exercise programs in preventing falls and enhancing mobility among people following stroke. This program, if

In the lower limb intervention group, individualised programs of weight-bearing balance and strengthening exercises will be prescribed. The upper limb/cognition group will receive exercises aimed at management and improvement of function of the affected upper limb and cognition carried out in the seated position. The primary outcome measures will be falls (measured with 12 month calendars) and mobility. Secondary outcome measures will be risk of falling, physical activity levels, community participation, quality of life, health service utilisation, upper limb function and cognition. This study aims to establish and evaluate community-based sustainable exercise programs for stroke survivors. We will determine the effects of the exercise programs in preventing falls and enhancing mobility among people following stroke. This program, if found to be effective, has the potential to be implemented within

    Rationale Stroke is a major cause of death and disability worldwide, yet 80% of strokes can be prevented through modifications of risk factors and lifestyle and by medication. While management strategies for primary stroke prevention in high cardiovascular disease risk individuals are well established, they are underutilized and existing practice of primary stroke prevention are inadequate. Behavioral interventions are emerging as highly promising strategies to improve cardiovascular disease risk factor management. Health Wellness Coaching is an innovative, patient-focused and cost-effective, multidimensional psychological intervention designed to motivate participants to adhere to recommended medication and lifestyle changes and has been shown to improve health and enhance well-being. Aims and/or hypothesis To determine the effectiveness of Health Wellness Coaching for primary stroke prevention in an ethnically diverse sample including Māori, Pacific Island, New Zealand European and Asian participants. Design A parallel, prospective, randomized, open-treatment, single-blinded end-point trial. Participants include 320 adults with absolute five-year cardiovascular disease risk ≥ 10%, calculated using the PREDICT web-based clinical tool. Randomization will be to Health Wellness Coaching or usual care groups. Participants randomized to Health Wellness Coaching will receive 15 coaching sessions over nine months. Study outcomes A substantial relative risk reduction of five-year cardiovascular disease risk at nine months post-randomization, which is defined as 10% relative risk reduction among those at moderate five-year cardiovascular disease risk (10-15%) and 25% among those at high risk (>15%). Discussion This clinical trial will determine whether Health Wellness Coaching is an effective intervention for reducing modifiable risk factors, and hence decrease the risk of stroke and cardiovascular disease.

    Policies are an important part of public health interventions, including in the area of sexually transmitted disease (STD) prevention. Similar to other tools used in public health, policies are often evaluated to determine their usefulness. Therefore, we conducted a nonsystematic review of policy evidence for STD prevention. Our review considers assessments or evaluations of STD prevention-specific policies, health care system policies, and other, broader policies that have the potential to impact STD prevention through social determinants of health. We also describe potential policy opportunity in these areas. It should be noted that we found gaps in policy evidence for some areas; thus, additional research would be useful for public health policy interventions for STD prevention.

    Knowing compliance with secondary prevention recommendations of stroke in primary care and to identify factors associated with compliance. Multi-centre cross-sectional. Health primary care centres in a metropolitan area (944,280 inhabitants). Patients aged 18years and over with ischemic brain disease diagnosis prior to 6months before the study. Clinical history records of demographic variables, risk factors and cardiovascular comorbidity, drugs, blood pressure values (BP), LDL-cholesterol and medical visits by doctor and nurses after the event. Good adherence was considered when BP <140/90 mmHg, LDL-cholesterol <100 mg/dL, smoking abstention and preventive drugs prescription (anti-platelet/anticoagulants, statins and angiotensin-converting-enzyme inhibitors/angiotensin-receptor-antagonists or diuretics) during the last 18months. A total of 21,976 patients, mean age 73.12 years (SD: 12.13), 48% women, 72.7% with stroke. Co-morbidity: hypertension 70.8%, dyslipidemia 55.1%, DM 30.9%, atrial fibrillation 14.1%, ischemic heart disease 13.5%, chronic renal failure 12.5%, heart failure 8.8%, peripheral arterial disease 6.2%, dementia 7.8%. No record was found for smoking in 3.7%, for BP in 3.5% and for LDL in 6.5%. Optimal control: abstention smoking in 3.7%, BP <140/90 in 65.7% and LDL <100 mg/dL in 41.0%. 86.2% anti-platelet/anticoagulants, 61.3% statins and 61.8% angiotensin-converting-enzyme inhibitors, angiotensin-receptor-antagonists or diuretic. Registration and risk factors control was higher in 66-79years aged and lower in 18-40years aged. The implementation of clinical guidelines recommendations for stroke prevention in primary care must be improved, especially among younger population. Organizational changes and more active involvement by professionals and strategies against therapeutic inertia must be taken. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    The influence of fibrates on cardiovascular risk has been the focus of several clinical trials. This Cochrane Collaboration Systematic Review evaluated the efficacy of fibrates for secondary prevention of cardiovascular events and stroke, analyzing 13 randomized controlled trials, in a total of 16 112 participants with a history of cardiovascular disease. Fibrates showed a protective effect for the composite outcome of non-fatal stroke, non-fatal myocardial infarction (MI) and vascular death, mainly due to reduction in the risk of non-fatal or fatal MI. Nonetheless, these results largely relied on studies including clofibrate, a drug withdrawn from the market in 2002. No statistically significant differences regarding adverse events were found between fibrates and placebo. Although insufficient to support the routine prescription of fibrates in this setting, this evidence should be taken into account when deciding on lipid-modifying therapy in dyslipidemic patients with a history of cardiovascular disease.

    Full Text Available Abstract Background Although cigarette smoking is a well-established risk factor for vascular disease, the genetic mechanisms that link cigarette smoking to an increased incidence of stroke are not well understood. Genetic variations within the genes of the inflammatory pathways are thought to partially mediate this risk. Here we evaluate the association of several inflammatory gene single nucleotide polymorphisms (SNPs with ischemic stroke risk among young women, further stratified by current cigarette smoking status. Methods A population-based case-control study of stroke among women aged 15–49 identified 224 cases of first ischemic stroke (47.3% African-American and 211 age-comparable control subjects (43.1% African-American. Several inflammatory candidate gene SNPs chosen through literature review were genotyped in the study population and assessed for association with stroke and interaction with smoking status. Results Of the 8 SNPs (across 6 genes analyzed, only IL6 SNP rs2069832 (allele C, African-American frequency = 92%, Caucasian frequency = 55% was found to be significantly associated with stroke using an additive model, and this was only among African-Americans (age-adjusted: OR = 2.2, 95% CI = 1.0–5.0, p = 0.049; risk factor adjusted: OR = 2.5, 95% CI = 1.0–6.5, p = 0.05. When stratified by smoking status, two SNPs demonstrated statistically significant gene-environment interactions. First, the T allele (frequency = 5% of IL6 SNP rs2069830 was found to be protective among non-smokers (OR = 0.30, 95% CI = 0.11–.082, p = 0.02, but not among smokers (OR = 1.63, 95% CI = 0.48–5.58, p = 0.43; genotype by smoking interaction (p = 0.036. Second, the C allele (frequency = 39% of CD14 SNP rs2569190 was found to increase risk among smokers (OR = 2.05, 95% CI = 1.09–3.86, p = 0.03, but not among non-smokers (OR = 0.93, 95% CI = 0.62–1.39, p = 0.72; genotype by smoking interaction (p = 0.039.

    Cryptogenic ischemic strokes constitute 20-30% of ischemic strokes, the majority of which are embolic strokes of undetermined source. The standard preventive treatment in these patients is usually acetylsalicylic acid. The Randomized, double-blind, Evaluation in secondary Stroke Prevention comparing the EfficaCy and safety of the oral Thrombin inhibitor dabigatran etexilate vs. acetylsalicylic acid in patients with Embolic Stroke of Undetermined Source (RE-SPECT ESUS) is designed to determine whether the oral thrombin inhibitor dabigatran, taken within three-months after embolic stroke of undetermined source, is superior to acetylsalicylic acid for prevention of recurrent stroke and to characterize the safety of dabigatran in this setting. Prospective, randomized, double-blind, multicenter trial in approximately 6000 patients and 550 centers with embolic stroke of undetermined source. Subjects are randomized to dabigatran or acetylsalicylic acid and treated for an expected minimum of six-months and up to approximately three-years. It is an event-driven trial aiming for 353 adjudicated primary outcome events. The primary efficacy outcome is time to first recurrent stroke (ischemic, hemorrhagic, or unspecified). Key secondary outcomes are time to first ischemic stroke and time to first occurrence in the composite outcome of nonfatal stroke, nonfatal myocardial infarction, and cardiovascular death. The primary safety outcome is major hemorrhage, including symptomatic intracranial hemorrhage. Acetylsalicylic acid is the most common antithrombotic given to patients with embolic strokes of undetermined source to reduce recurrence risk. This trial will determine whether anticoagulation with dabigatran is more effective than acetylsalicylic acid, and acceptably safe. © 2015 World Stroke Organization.

  8. A heart-healthy and "stroke-free" world through policy development, systems change, and environmental supports: a 2020 vision for sub-Saharan Africa.

    Mensah, George A

    2003-01-01

    The vision of a heart-healthy and "stroke-free" world is achievable through the aggressive prevention and control of cardiovascular risk factors. In sub-Saharan Africa, a region plagued by infectious and parasitic diseases, nutritional deficiencies, and excessive maternal and perinatal morbidity and mortality, the prevention of cardiovascular diseases (CVD) and risk factors is rarely on the public health agenda. In Africa, however, as recently documented by the World Health Organization's Africa Regional Office, CVD and other chronic non-communicable diseases are on the increase and already represent a significant burden on public health services. Age-specific mortality and morbidity associated with CVD and chronic diseases are higher in sub-Saharan Africa than in established market economies. Correspondingly, adverse trends in risk factor profile are beginning to appear especially in many urban centers in sub-Saharan Africa. Addressing and reversing these trends will take more than just targeting individuals and their behaviors and lifestyle choices. More importantly, to support heart-healthy choices, emphasis must be placed on policy development, systems changes, and issues in the social environment factors such as the need to strengthen legislation and regulatory mechanisms, which control the leading risk factors (eg, tobacco, physical inactivity, and poor nutrition). We must develop and conduct heart-healthy and "stroke-free" initiatives to take place in diverse community settings: schools, worksites, communities, and healthcare systems. In addition, public health capacity and infrastructure must be strengthened to provide adequate surveillance and the assurance that best practices are implemented. Action is needed to integrate health promotion, risk factor control and disease prevention within the primary healthcare setting. Above all, population-based approaches must be used to promote education and awareness of the importance of CVD risk factors. In sub

    Abstract Background: Previous study indicated that high-dose statin treatment might increase the risk of hemorrhagic stroke and adverse reactions. We aim to compare the efficacy and safety of intensive-dose and standard-dose statin treatment for preventing stroke in high-risk patients. Methods: A thorough search was performed of multiple databases for publications from 1990 to June 2015. We selected the randomized clinical trials comparing standard-dose statin with placebo and intensive-dose statin with standard-dose statin or placebo for the prevention of stroke events in patients. Duplicate independent data extraction and bias assessments were performed. Data were pooled using a fixed-effects model or a random-effects model if significant heterogeneity was present. Results: For the all stroke incidences, intensive-dose statin treatment compared with placebo treatment and standard-dose statin treatment compared with placebo treatment showed a significant 21% reduction in relative risk (RR) (RR 0.79, 95% confidence interval (CI) [0.71, 0.87], P statin treatment compared with standard dose or placebo was effective reducing fatal stroke (RR 0.61, 95% CI [0.39, 0.96], P = 0.03) and the RR was 1.01 (95% CI [0.85, 1.20], P = 0.90) in standard-dose statin treatment compared with placebo. Conclusion: The results of this meta-analysis suggest that intensive-dose statin treatment might be more favorable for reducing the incidences of all strokes than standard-dose statin treatment, especially for patients older than 65 years in reducing the incidences of all stroke incidences.

    OBJECTIVE Sickle cell disease (SCD) in combination with moyamoya syndrome (MMS) represents a rare complication of SCD, with potentially devastating neurological outcomes. The effectiveness of surgical revascularization in this patient population is currently unclear. The authors' aim was to determine the effectiveness of surgical intervention in their series of SCD-MMS patients by comparing stroke recurrence in those undergoing revascularization and those undergoing conservative transfusion therapy. METHODS The authors performed a retrospective chart review of patients with MMS who were seen at the Johns Hopkins Medical Institution between 1990 and 2013. Pediatric patients (age < 18 years) with confirmed diagnoses of SCD and MMS were included. Intracranial stroke occurrence during the follow-up period was compared between surgically and conservatively managed patients. RESULTS A total of 15 pediatric SCD-MMS patients (28 affected hemispheres) were included in this study, and all were African American. Seven patients (12 hemispheres) were treated with indirect surgical revascularization. The average age at MMS diagnosis was 9.0 ± 4.0 years, and 9 patients (60.0%) were female. Fourteen patients (93.3%) had strokes before diagnosis of MMS, with an average age at first stroke of 6.6 ± 3.9 years. During an average follow-up period of 11.6 years, 4 patients in the conservative treatment group experienced strokes in 5 hemispheres, whereas no patient undergoing the revascularization procedure had any strokes at follow-up (p = 0.029). Three patients experienced immediate postoperative transient ischemic attacks, but all recovered without subsequent strokes. CONCLUSIONS Indirect revascularization is suggested as a safe and effective alternative to the best medical therapy alone in patients with SCD-MMS. High-risk patients managed on a regimen of chronic transfusion should be considered for indirect revascularization to maximize the effect of stroke prevention.

    To examine the impact of a healthy lifestyle on stroke risk in men at higher risk of stroke because of other cardiovascular diseases or conditions. Our study population comprised 11,450 men in the Cohort of Swedish Men who had a history of hypertension, high cholesterol levels, diabetes, heart failure, or atrial fibrillation. Participants had completed a questionnaire about diet and lifestyle and were free from stroke and ischemic heart disease at baseline (January 1, 1998). We defined a healthy lifestyle as a low-risk diet (≥5 servings/d of fruits and vegetables and 0 to ≤30 g/d). Ascertainment of stroke cases was accomplished through linkage with the National Inpatient Register and the Swedish Cause of Death Register. During a mean follow-up of 9.8 years, we ascertained 1,062 incident stroke cases. The risk of total stroke and stroke types decreased with increasing number of healthy lifestyle factors. The multivariable relative risk of total stroke for men who achieved all 5 healthy lifestyle factors compared with men who achieved 0 or 1 factor was 0.28 (95% confidence interval 0.14-0.55). The corresponding relative risks (95% confidence interval) were 0.31 (0.15-0.66) for ischemic stroke and 0.32 (0.04-2.51) for hemorrhagic stroke. A healthy lifestyle is associated with a substantially reduced risk of stroke in men at higher risk of stroke. © 2015 American Academy of Neurology.

  17. Egyptian FGM policy fails to prevent girl's death.

    Science.gov (United States)

    1996-09-06

    The form of female genital mutilation (FGM) predominantly practiced throughout Egypt consists of the surgical removal of the clitoris and often the inner labia. The practice reduces the level of a woman's sexual sensation and causes pain, psychological trauma, and the risk of infection and hemorrhage. An estimated 80% of Egyptian girls undergo the procedure. Egypt's Ministry of Health in 1994 decided to permit only doctors in government hospitals to perform FGM. This policy was adopted in an effort to make safer what was considered to be an inevitable practice. However, the policy was revoked in October 1995 after women's rights and health advocates criticized it as a government endorsement of FGM. An 11-year-old Nile Delta girl died July 12, 1996, as a result of FGM. The Health Ministry subsequently banned all registered health professionals from performing FGM. Two months later, on August 24, a 14-year-old girl died from hemorrhaging shortly after undergoing FGM. These recent deaths challenge the effectiveness of Egypt's new attempts to prevent FGM. Barbers and midwives in Egypt perform thousands of mutilations annually. While they are theoretically subject to criminal penalties for performing surgery without a license, the laws are rarely enforced. Furthermore, despite existing regulations, no provision in the Egyptian penal code criminalizes FGM.

    risk and/or bleeding risk within the decision-making. At the 'latent-level' analysis, three overarching themes emerged: (i) The practical ease of managing NOACs over warfarin; (ii) Unbalanced explanation about stroke risk versus bleeding risk; and (iii) Individualized antithrombotic therapy selection. In general, the benefit of stroke prevention with anticoagulant use was emphasized less compared to the risk of bleeding. Overall, one in four resources had an implied preference for either warfarin or the NOACs. The implied inclination of some resources towards particular anticoagulant therapies and imbalanced information about the importance of anticoagulation in AF might misinform and confuse patients. Patients' engagement in shared decision-making and adherence to medicines may be undermined by the suboptimal quality of information provided in the resources. Health professionals have an important role to play in referring patients to appropriate resources to enable patient engagement in shared decision-making when selecting treatment. © 2016 John Wiley & Sons Ltd.

    After stroke, up to 81% of individuals develop shoulder subluxation, a condition frequently associated with poor upper limb function. Recently, electrical stimulation has been applied to shoulder muscles to treat shoulder subluxation. The purpose of this meta-analysis was to examine the efficacy of surface electrical stimulation for the prevention or reduction of shoulder subluxation after stroke. A meta-analysis of all eligible randomised or quasi-randomised trials of electrical stimulation for the treatment of shoulder subluxation identified by computerised and hand searches of the literature was carried out. The primary outcome measure of interest was subluxation. Seven (four early and three late) trials met the inclusion criteria. The mean PEDro score out of 10 for quality of the methods was 5.8 for the four early trials and 4.3 for the three late trials. Data were pooled when subluxation was measured in millimetres. Analysis found that, when added to conventional therapy, electrical stimulation prevented on average 6.5mm of shoulder subluxation (weighted mean difference, 95% CI 4.4 to 8.6) but only reduced it by 1.9mm (weighted mean difference, 95% CI -2.3 to 6.1) compared with conventional therapy alone. Therefore, evidence supports the use of electrical stimulation early after stroke for the prevention of, but not late after stroke for the reduction of, shoulder subluxation.

    Full Text Available Guidelines recommend implementation of multimodal interventions to help prevent recurrent TIA/stroke. We undertook a systematic review to assess the effectiveness of behavioral secondary prevention interventions.Searches were conducted in 14 databases, including MEDLINE (1980-January 2014. We included randomized controlled trials (RCTs testing multimodal interventions against usual care/modified usual care. All review processes were conducted in accordance with Cochrane guidelines.Twenty-three papers reporting 20 RCTs (6,373 participants of a range of multimodal behavioral interventions were included. Methodological quality was generally low. Meta-analyses were possible for physiological, lifestyle, psychosocial and mortality/recurrence outcomes. Note: all reported confidence intervals are 95%. Systolic blood pressure was reduced by 4.21 mmHg (mean (-6.24 to -2.18, P = 0.01 I2 = 58%, 1,407 participants; diastolic blood pressure by 2.03 mmHg (mean (-3.19 to -0.87, P = 0.004, I2 = 52%, 1,407 participants. No significant changes were found for HDL, LDL, total cholesterol, fasting blood glucose, high sensitivity-CR, BMI, weight or waist:hip ratio, although there was a significant reduction in waist circumference (-6.69 cm, -11.44 to -1.93, P = 0.006, I2 = 0%, 96 participants. There was no significant difference in smoking continuance, or improved fruit and vegetable consumption. There was a significant difference in compliance with antithrombotic medication (OR 1.45, 1.21 to 1.75, P<0.0001, I2 = 0%, 2,792 participants and with statins (OR 2.53, 2.15 to 2.97, P< 0.00001, I2 = 0%, 2,636 participants; however, there was no significant difference in compliance with antihypertensives. There was a significant reduction in anxiety (-1.20, -1.77 to -0.63, P<0.0001, I2 = 85%, 143 participants. Although there was no significant difference in odds of death or recurrent TIA/stroke, there was a significant reduction in the odds of cardiac events (OR 0.38, 0

    The aim of the study was to evaluate the prevalence of resistance to acetylsalicylic acid (ASA), used for secondary prevention of stroke, including the assessment of risk factors associated with the lack of ASA anti-aggregatory action. Patients after a transient ischaemic attack (TIA) or ischaemic stroke in the acute (n = 111) and chronic phase (n = 87) were enrolled in the study. The assessment of platelet function was performed by whole blood impedance aggregometry using a multi-channel platelet function analyser (Multiplate). A proper response to ASA was found in 121 patients (61.1%) (ASA responders), a partial response to ASA in 59 patients (29.8%) (ASA partial responders), and ASA resistance in 18 patients (9.1%) (ASA non-responders). Acetylsalicylic acid resistance was observed more frequently in the chronic phase. The mean low-density lipoprotein (LDL) concentration was higher in ASA non-responders (p = 0.02). The mean heart rate (p = 0.03) and the mean haematocrit (p = 0.03) were higher in the group of ASA partial responders and ASA non-responders. Angiotensin II receptor antagonists were more often used in the group of ASA partial responders and ASA non-responders (p = 0.04). Diuretics were more rarely used by ASA non-responders, whereas fibrates were more rarely used by ASA partial responders. The method enabled the detection of ASA resistance in some patients with cerebrovascular disease. The study revealed some possible risk factors of ASA resistance: long ASA therapy, increased heart rate, higher LDL concentration, and higher haematocrit value. The relationship between the effect of ASA and other medications (angiotensin II receptor blockers, fibrates, diuretics) requires further study. Platelet function monitoring should be considered in patients at a greater risk of ASA resistance.

    Current European atrial fibrillation (AF) guidelines have assigned a strong recommendation for the initiation of antithrombotic therapy to prevent thromboembolism in all but those AF patients at low risk (or with contraindications). Furthermore, the selection of antithrombotic therapy is based on the absolute risks of thromboembolism and bleeding, and the relative risk and benefit for a given patient. By their very mechanism of action, antithrombotic agents used for stroke prevention in AF will potentially increase the risk of bleeding events. Moreover, the introduction of novel oral anticoagulation agents have introduced new, hitherto ill-defined, deficiencies in the authors' knowledge with respect to anticoagulation monitoring, availability of direct antidotes, drug-drug interactions and the ability to appropriately control and reverse their actions if bleeding events occur. The authors present a comprehensive review on all aspects of bleeding related to currently licensed antithrombotic agents used for stroke prevention in patients with AF.

    An American Heart Association/American Stroke Association (AHA/ASA) writing committee has recently recommended that tissue evidence of cerebral infarction associated with temporary symptoms (CITS) lasting Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) trial. We compared outcomes in the medical (n = 227) and stenting (n = 224) groups in SAMMPRIS using the following primary end point (new components in bold): any stroke, CITS, or death within 30 days after enrollment or within 30 days after a revascularization procedure for the qualifying lesion during follow-up; or ischemic stroke or CITS in the territory of the qualifying artery beyond 30 days. We also compared the use of brain magnetic resonance imaging (MRI) after transient ischemic attacks (TIAs) in both treatment groups. By considering CITS as equivalent to stroke, the number of primary end points increased from 34 to 43 in the medical group and from 52 to 66 in the stenting group of SAMMPRIS. The Kaplan-Meier curves for the primary end points in the 2 groups were significantly different (P = .009). The percentage of patients with reported TIAs who underwent brain MRI was 69% in the medical group and 61% in the stenting group (P = .40). Using the AHA/ASA definition of stroke resulted in a substantially higher primary end point rate in both treatment groups and an even higher benefit from medical therapy over stenting than originally shown in SAMMPRIS. The higher rate of CITS in the stenting group was not due to ascertainment bias. Published by Elsevier Inc.

    Sudden death and catastrophic injuries during sport can be attenuated with the implementation of evidence-based health and safety policies. However, the extent of the implementation of these policies within secondary school athletics is unknown. To provide an assessment of the implementation of health and safety policies pertaining to the leading causes of sudden death and catastrophic injuries in sport within secondary school athletics in the United States. Descriptive epidemiology study. A rubric for evidence-based practices for preventing the leading causes of death and catastrophic injuries in sport was created. The rubric comprised 5 equally weighted sections for sudden cardiac arrest, head injuries, exertional heat stroke, appropriate medical coverage, and emergency preparedness. State high school athletic association (SHSAA) policies, enacted legislation, and Department of Education policies were extensively reviewed for all 50 states and the District of Columbia. States meeting the specific criteria in the rubric, which required policies to be mandated for all SHSAA member schools, were awarded credit; the weighted scores were tabulated to calculate an aggregate score. States were then ranked from 1 (best) to 51 (worst) based on the aggregate score achieved. The median score on the rubric was 47.1% (range, 23.00%-78.75%). States ranked 1 through 10 (from 78.75% to 56.98%) were North Carolina, Kentucky, Massachusetts, New Jersey, South Dakota, Missouri, Washington, Hawaii, Wisconsin, and Georgia, respectively. States ranked 11 through 20 (from 56.03% to 50.55%) were Arkansas, New York, Mississippi, West Virginia, Oregon, Illinois, Tennessee, Arizona, Texas, and District of Columbia, respectively. States ranked 21 through 30 (from 49.40% to 44.00%) were Virginia, Pennsylvania, Florida, New Mexico, Alabama, Maine, Rhode Island, Indiana, Nevada, and Utah, respectively. States ranked 31 through 40 (from 43.93% to 39.80%) were Ohio, Delaware, Alaska, Vermont

    Stroke is one of the major public health challenges in middle-income countries. Brazil is the world's sixth largest economy but was clearly behind the milestones in the fight against stroke, which is the leading cause of death and disability in the country. Nevertheless, many initiatives are now reshaping stroke prevention, care, and rehabilitation in the country. The present article discusses the evolution of stroke care in Brazil over the last decade. We describe the main characteristics of stroke care before 2008; a pilot study in a Southern Brazilian city between 2008 and 2010, the Brazilian Stroke Project initiative; and the 2012 National Stroke Policy Act. The National Stroke Project was followed by a major increased on the number of stroke center in the country. The key elements of the 2012 National Stroke Policy Act included: definition of the requirements and levels of stroke centers; improved reimbursement for stroke care; promotion of stroke telemedicine; definition of the Line of Stroke Care (to integrate available resources and other health programs); increased funding for stroke rehabilitation; funding for training of healthcare professionals and initiatives to increase awareness about stroke within the population. The evolution of stroke care in Brazil over the last decade is a pathway that exemplifies the challenges that middle-income countries have to face in order to improve stroke prevention, treatment and rehabilitation. The reported Brazilian experience can be extrapolated to understand the past, present, and future of stroke care in middle-income countries. © 2013 The Authors.

    Number-needed-to-treat describes the magnitude of the effect of an intervention, underpins health economic analyses, and is typically calculated for binary events. Ordered categorical outcomes provide more clinical information and their analysis using ordinal approaches is usually more efficient statistically. However, to date, techniques to calculate number-needed-to-treat based on ordinal outcomes for parallel group trials have had important limitations. Aims Numbers-needed-to-treat may be calculated for ordinal data from parallel group trials by using an unmatched comparison of all subjects or by generating matched pairs of patients nested within the study. The above approaches were assessed and compared with numbers-needed-to-treat calculated for binary outcomes using individual patient data from acute and prevention stroke trials testing the effect of interventions of varying utility and efficacy. Numbers-needed-to-treat were generally lower numerically for ordinal vs. binary, and matched vs. unmatched analyses, and the lowest in highly efficacious interventions: hemicraniectomy, ordinal matched 2.4 vs. ordinal unmatched 2.5 vs. binary matched 12 vs. binary unmatched 9 (one trial, 12 month outcome); alteplase, 4.5 vs. 6.6 vs. 8.4 vs. 8.4 (one trial with two parts, three-months); aspirin, 42 vs. 58 vs. 76 vs. 80 (one trial, six-months); and stroke units, 3.6-5.3 vs. 6.2 vs. 4.7-5.9 vs. 6.3-7.0 (two trials, three- to 60 months). Similar trends were seen for aspirin/dipyridamole vs. aspirin in secondary prevention, 22 vs. 20 vs. 31 vs. 31 (one trial, 24 months). Number-needed-to-treat may be calculated for ordinal outcome data derived from parallel group stroke trials; such numbers-needed-to-treat are lower than those calculated for binary outcomes. Their use complements the use of ordinal statistical approaches in the analysis of ordered categorical data. © 2011 The Authors. International Journal of Stroke © 2011 World Stroke Organization.

    Novel oral anticoagulants are emerging options for the prevention and treatment of thromboembolic diseases. They are increasingly used in clinical practice due to their simplicity of use and clinical benefits, but an important step is to evaluate their cost-effectiveness. The aim of the AFFORD study (A Review of Cost EFFectiveness of Novel ORal Anticoagulant Drugs) was to perform a systematic review of cost-effectiveness studies of novel oral anticoagulants for stroke prevention in non-valvular atrial fibrillation (AF). A systematic review of the literature was conducted by searching the PubMed, Embase, Scopus, Cochrane and Web of Knowledge databases to identify all cost-effectiveness studies of novel oral anticoagulants for stroke prevention in AF. The search identified 27 studies, 18 with dabigatran, three with apixaban, two with rivaroxaban and four with at least two of these drugs. The incremental cost-effectiveness ratios were 30 405 ± 16 101 euros per quality-adjusted life-year (QALY) for dabigatran 110 mg, 17 566 ± 16 902 euros/QALY for dabigatran 150 mg, 8102 ± 3252 euros/QALY for age-adjusted dabigatran, 11 897 ± 3341 euros/QALY for apixaban and 17 960 ± 12 005 euros/QALY for rivaroxaban. The present systematic review demonstrates that novel oral anticoagulants are cost-effective for stroke prevention in AF. Copyright © 2014 Sociedade Portuguesa de Cardiologia.

    Stroke risk may be more than 3-fold higher among patients with chronic kidney disease stage 5D (CKD-5D) compared to the general population, with the highest stroke rates noted among those 85 years and older. Atrial fibrillation (AF), a strong risk factor for stroke, is the most common arrhythmia and affects >7% of the population with CKD-5D. Warfarin use is widely acknowledged as an important intervention for stroke prevention with nonvalvular AF in the general population. However, use of oral anticoagulants for stroke prevention in patients with CKD-5D and nonvalvular AF continues to be debated by the nephrology community. In this National Kidney Foundation-Kidney Disease Outcomes Quality Initiative (NKF-KDOQI) controversies report, we discuss the existing observational studies that examine warfarin use and associated stroke and bleeding risks in adults with CKD-5D and AF. Non-vitamin K-dependent oral anticoagulants and their potential use for stroke prevention in patients with CKD-5D and nonvalvular AF are also discussed. Data from randomized clinical trials are urgently needed to determine the benefits and risks of oral anticoagulant use for stroke prevention in the setting of AF among patients with CKD-5D.

    Full Text Available Stroke is the leading cause of death in every hospital in Indonesia. The death rate of newly formed or recurrent stroke is estimated around 750.000 case every year nation wide, 200.000 of which are recurrent stroke. Stroke patients have higher risk to develop another stroke attack. In 5 years time, the recurrence of stroke attack is estimated around 30–43%. In many cases, elderly stroke patients who were admitted to the hospital with recurrent stroke attack also suffer from anorexia which leads to hypoalbuminemia, hyponatremia, hypokalemia and impaired renal function marked by a rise in ureum level with or without elevation in blood creatinin levels. This study uses pre and post nutrition intervention method. Hospital’s fermented soybean cake and albumin blend formula was given through nasogastric tube. The amount of calorie was adjusted according to basal needs x 1,3 and consisted of carbohydrate, protein 1 gram/kg BB (albumin : fermented soybean cake=3:1 and 25% fat. This formula was given to 11 stroke patients who had been admitted to Atma Jaya Hospital for at least 10 days and met the inclusion & exclusion criteria, such as did not receive parenteral blood and albumin transfusion without history of renal failure. All the patients’ intake and fluid balance were monitored. The average albumin level of these patients was ±3,1 mg/dL(pre intervention. After receiving nutrition (NGT and fluid (parenteral nutrition intervention, the result is as follows: There was an average of±5 mg increase in Natrium level during day 3–5 of hospital stay. There was an average of±0,3 mg increase in Kalium level during day 2–3 of hospital stay. There was an average of ±15 mg reduction of Ureum level during day 5–7 of hospital stay When there was inadequate calorie intake, protein from muscle might be broken down marked by a rise in blood ureum level with or without an increase in creatinin level. In this condition, electrolyte level, such as

    World War I catapulted the United States from traditional isolationism to international involvement in a major European conflict. Woodrow Wilson envisaged a permanent American imprint on democracy in world affairs through participation in the League of Nations. Amid these defining events, Wilson suffered a major ischemic stroke on October 2, 1919, which left him incapacitated. What was probably his fourth and most devastating stroke was diagnosed and treated by his friend and personal physician, Admiral Cary Grayson. Grayson, who had tremendous personal and professional loyalty to Wilson, kept the severity of the stroke hidden from Congress, the American people, and even the president himself. During a cabinet briefing, Grayson formally refused to sign a document of disability and was reluctant to address the subject of presidential succession. Wilson was essentially incapacitated and hemiplegic, yet he remained an active president and all messages were relayed directly through his wife, Edith. Patient-physician confidentiality superseded national security amid the backdrop of friendship and political power on the eve of a pivotal juncture in the history of American foreign policy. It was in part because of the absence of Woodrow Wilson's vocal and unwavering support that the United States did not join the League of Nations and distanced itself from the international stage. The League of Nations would later prove powerless without American support and was unable to thwart the rise and advance of Adolf Hitler. Only after World War II did the United States assume its global leadership role and realize Wilson's visionary, yet contentious, groundwork for a Pax Americana. The authors describe Woodrow Wilson's stroke, the historical implications of his health decline, and its impact on United States foreign policy.

    Sepsis is one of the leading causes of death worldwide. While the management of critically ill patients with sepsis is certainly better now compared to 20 years ago, sepsis-associated mortality remains unacceptably high. Annual deaths from sepsis in both children and adults far surpass the number of deaths from acute myocardial infarction (AMI), stroke, or cancer. Given the substantial toll that sepsis takes worldwide, prevention of sepsis remains a global priority. Multiple effective prevent...

    To review the nursing outcome, Fall Prevention Behavior, and clinically validate its indicators in people with stroke. A methodological study performed with 106 patients in two outpatient clinics, from July to September of 2013. Two pairs of trained nurses applied the NOC scale, one with and one without the use of operational definitions. The internal consistency, stability and difference between the medians obtained by nurses were compared within and between pairs. Most participants were men, elderly, with low education and income. Statistically significant differences were noted in twelve indicators. Five indicators had different means that were greater than the least significant difference. The indicators were statistically significant; the internal consistency was similar between the pairs and the intraclass correlation coefficient was more satisfactory in the pair that used the definitions. Thus, the construction of empirical referents and the clinical validation process makes the nursing indicators and outcomes more adequate for specific populations and provides an effective means to better evaluate the nursing actions.

    Aquaporin 4 (AQP4) is a water-selective transport protein expressed in astrocytes throughout the central nervous system. AQP4 level increases after cerebral ischemia and results in ischemic brain edema. Brain edema markedly influences mortality and motor function by elevating intracranial pressure that leads to secondary brain damage. Therefore, AQP4 is an important target to improve brain edema after cerebral ischemia. The Japanese herbal Kampo medicine, goreisan, is known to inhibit AQP4 activity. Here, we investigated whether goreisan prevents induction of brain edema by cerebral ischemia via AQP4 using 4-hour middle cerebral artery occlusion (4h MCAO) mice. Goreisan was orally administered at a dose of 500 mg/kg twice a day for 5 days before MCAO. AQP4 expression and motor coordination were measured by Western blotting and rotarod test, respectively. Brain water content of 4h MCAO mice was significantly increased at 24 hours after MCAO. Treatment with goreisan significantly decreased both brain water content and AQP4 expression in the ischemic brain at 24 hours after MCAO. In addition, treatment with goreisan alleviated motor coordination deficits at 24 hours after MCAO. The results of this study suggested that goreisan may be a useful new therapeutic option for ischemic brain edema. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

    2018-04-01

    Edoxaban is the most recent available representative of the Non-Vitamin K antagonist oral anticoagulants (NOAC). The approval was based on the largest phase III trials of NOACs for stroke prevention in patients with non-valvular atrial fibrillation (AF, ENGAGE-AF), and for the treatment of venous thromboembolism (VTE, HOKUSAI-VTE). In both trials, edoxaban was associated with similar efficacy and a significant reduction in bleeding events with respect to the pre-defined primary safety endpoints, as compared to warfarin.Additionally, the once daily dosing of edoxaban, the clinically investigated strategy for dose-reduction based on clearly defined criteria and the favorable pharmacokinetic profile might further support the clinical applicability of the substance.In the light of recent data, this expert consensus document aims to summarize the latest clinical trial results while providing a concise overview of current guideline recommendations on the management of patients with non-valvular AF and VTE.

    We sought to evaluate the success rates in achieving preventive therapeutic goals in patients who experienced an ischemic stroke (IS) and compare them with those achieved in patients with coronary artery disease (CAD). This was an observational multicenter case-control study (3 patients with IS and one control subject with CAD) performed in 1444 primary health centers in Spain. Preventive therapeutic objectives according to American Heart Association guidelines were predefined. Demographic data, vascular risk factors, and success/failure in achievement of objectives were recorded and compared between patients with IS and CAD. A total of 5458 patients were included, 4098 (75.1%) had IS and 1360 (24.9%) had CAD. Although more than 90% of patients with hypertension, diabetes, or dyslipidemia were under specific drug regimens, only about 25% achieved the recommended therapeutic objective for each risk factor. Success rate was especially low among patients with IS compared with CAD: hypertension (23.8% v 27.2%; P = .028); dyslipidemia (13.6% v 20.3%; P risk factors under control, compared with 5.6% of those with CAD (P = .006). For all patients, multivariate logistic regression model showed that independent predictors of full risk factor control were: presence of CAD as compared with IS (odds ratio [OR] 2.11; 95% confidence interval [CI] 1.35-3.29; P = .001), older age (OR 1.02; 95% CI 1.00-1.04; P = .028), and having less than 3 risk factors (OR 16.98; 95% CI 9.02-31.97; P risk factor control.

    Atrial fibrillation (AF), the most common cardiac arrhythmia, confers a 5-fold risk of stroke that increases to 17-fold when associated with mitral stenosis. At this time, the most effective long-term solution to protect patients from stroke and thromboembolism is oral anticoagulation, either with vitamin K antagonists (VKAs) or a novel oral anticoagulant (NOAC). Despite the significant benefits they confer, both VKAs and NOACs are underused because of their increased potential for bleeding, and VKAs are underused because of their narrow therapeutic range, need for regular international normalized ratio checks, and interactions with food or medications. In patients with nonvalvular AF, approximately 90% of strokes originate from the left atrial appendage (LAA); in patients with rheumatic mitral valve disease, many patients (60%) have strokes that originate from the left atrium itself. Surgical LAA amputation or closure, although widely used to reduce stroke risk in association with cardiac surgery, is not currently performed as a stand-alone operation for stroke risk reduction because of its invasiveness. Percutaneous LAA closure, as an alternative to anticoagulation, has been increasingly used during the last decade in an effort to reduce stroke risk in nonvalvular AF. Several devices have been introduced during this time, of which one has demonstrated noninferiority compared with warfarin in a randomized controlled trial. This review describes the available technologies for percutaneous LAA closure, as well as a summary of the published trials concerning their safety and efficacy in reducing stroke risk in AF.

    Aspiration due to dysphagia is a factor associated with pneumonia during acute stroke. In such cases, it is likely that secretions in the pyriform sinuses enter the laryngeal inlet. The present study was based on the idea that it is possible to reduce aspiration pneumonia by periodically suctioning and removing such secretions (pyriform sinus suctioning), a study was conducted in a single facility. The incidence of pneumonia as a dependent variable was compared between before (control) and after (intervention group) intervention with pyriform sinus suctioning as an independent variable. With a view of unifying the quality and frequency of intervention, two programs to: initially confirm the safety of such suctioning; subsequently enhance/evaluate knowledge and skills related to the procedure (educational); and specify conditions for the implementation and criteria for determining its appropriateness (practical), were developed. The study involved 33 (mean age: 74.6 ± 12.4) and 30 (80.0 ± 8.8) control and intervention group members, respectively, 25 (83.3%) of the latter were treated with pyriform sinus suctioning for 5 days after a stroke. Pneumonia developed in 7 (21.2%) and 2 (6.7%) of the former and latter, respectively. As individuals with a Japan Coma Scale (JCS) score of III or a midline shift on head CT tend to develop pharyngeal dysphagia, the patients were also divided into 2 groups to compare the incidence of pneumonia based on the risk level: low: Japan Coma Scale scores of I-II without a midline shift on head CT; and high: scores of II-III with it. In the latter, the incidence after intervention was markedly lower (p = 0.06, φ = 0.326), while the former did not show changes (p = 0.574, φ = 0.066), supporting the effectiveness of pyriform sinus suctioning to prevent aspiration pneumonia among patients with a low risk level.

    The use of oral anticoagulant therapy for stroke prevention in atrial fibrillation has been transformed by the availability of the nonvitamin K antagonist oral anticoagulants. Real-world studies on the use of nonvitamin K antagonist oral anticoagulants would help elucidate their effectiveness and safety in daily clinical practice. Apixaban was the third nonvitamin K antagonist oral anticoagulants introduced to clinical practice, and increasing real-world studies have been published. Our aim was to summarize current evidence about real-world studies on apixaban for stroke prevention in atrial fibrillation. We performed a systematic review and meta-analysis of all observational real-world studies comparing apixaban with other available oral anticoagulant drugs. From the original 9680 results retrieved, 16 studies have been included in the final meta-analysis. Compared with warfarin, apixaban regular dose was more effective in reducing any thromboembolic event (odds ratio: 0.77; 95% confidence interval: 0.64-0.93), but no significant difference was found for stroke risk. Apixaban was as effective as dabigatran and rivaroxaban in reducing thromboembolic events and stroke. The risk of major bleeding was significantly lower for apixaban compared with warfarin, dabigatran, and rivaroxaban (relative risk reduction, 38%, 35%, and 46%, respectively). Similarly, the risk for intracranial hemorrhage was significantly lower for apixaban than warfarin and rivaroxaban (46% and 54%, respectively) but not dabigatran. The risk of gastrointestinal bleeding was lower with apixaban when compared with all oral anticoagulant agents ( P stroke and any thromboembolic events when compared with warfarin. A better safety profile was found with apixaban compared with warfarin, dabigatran, and rivaroxaban. © 2017 American Heart Association, Inc.

  9. Adjusting the fairshare policy to prevent computing power loss

    On a typical WLCG site providing batch access to computing resources according to a fairshare policy, the idle time lapse after a job ends and before a new one begins on a given slot is negligible if compared to the duration of typical jobs. The overall amount of these intervals over a time window increases with the size of the cluster and the inverse of job duration and can be considered equivalent to an average number of unavailable slots over that time window. This value has been investigated for the Tier-1 at CNAF, and observed to occasionally grow and reach up to more than the 10% of the about 20,000 available computing slots. Analysis reveals that this happens when a sustained rate of short jobs is submitted to the cluster and dispatched by the batch system. Because of how the default fairshare policy works, it increases the dynamic priority of those users mostly submitting short jobs, since they are not accumulating runtime, and will dispatch more of their jobs at the next round, thus worsening the situation until the submission flow ends. To address this problem the default behaviour of the fairshare have been altered by adding a correcting term to the default formula for the dynamic priority. The LSF batch system, currently adopted at CNAF, provides a way to define its value by invoking a C function, which returns it for each user in the cluster. The correcting term works by rounding up to a minimum defined runtime the most recently done jobs. Doing so, each short job looks almost like a regular one and the dynamic priority value settles to a proper value. The net effect is a reduction of the dispatching rate of short jobs and, consequently, the average number of available slots greatly improves. Furthermore, a potential starvation problem, actually observed at least once is also prevented. After describing short jobs and reporting about their impact on the cluster, possible workarounds are discussed and the selected solution is motivated. Details on the

    It is widely supposed, but not well-demonstrated, that cumulative advances in standard care have reduced recurrent stroke and cardiovascular events in secondary prevention trials. Systematic search identified all randomized, controlled trials of medical secondary stroke prevention therapies published from 1960 to 2009. Randomized, controlled trials narrowly focused on single stroke mechanisms, including atrial fibrillation, cervical carotid stenosis, and intracranial stenosis, were excluded. From control arms of individual trials, we extracted data for baseline characteristics and annual event rates for recurrent stroke, fatal stroke, and major vascular events and analyzed trends over time. Fifty-nine randomized controlled trials were identified, enrolling 66 157 patients in control arms. Over the 5 decade periods, annual event rates declined, per decade, for recurrent stroke by 0.996% (P=0.001), fatal stroke by 0.282% (P=0.003), and major vascular events by 1.331% (P=0.001). Multiple regression analyses identified increasing antithrombotic use and lower blood pressures as major contributors to the decline in recurrent stroke. For recurrent stroke, annual rates fell from 8.71% in trials launched in the 1960s to 6.10% in the 1970s, 5.41% in the 1980s, 4.04% in the 1990s, and 4.98% in the 2000s. The sample size required for a trial to have adequate power to detect a 20% reduction in recurrent stroke increased 2.2-fold during this period. Recurrent stroke and vascular event rates have declined substantially over the last 5 decades, with improved blood pressure control and more frequent use of antiplatelet therapy as the leading causes. Considerably larger sample sizes are now needed to demonstrate incremental improvements in medical secondary prevention.

    Patent foramen ovale closure represents a potential secondary prevention strategy for cryptogenic stroke, but available trials have varied by size, device studied, and follow-up. We conducted a systematic search of published randomized clinical trials evaluating patent foramen ovale closure versus medical therapy in patients with recent stroke or transient ischemic attack using PubMED, EMBASE, and Cochrane through September 2017. Weighting was by random effects models. Of 480 studies screened, we included 5 randomized clinical trials in the meta-analysis in which 3440 patients were randomized to patent foramen ovale closure (n = 1829) or medical therapy (n = 1611) and followed for an average of 2.0 to 5.9 years. Index stroke/transient ischemic attack occurred within 6 to 9 months of randomization. The primary end point was composite stroke/transient ischemic attack and death (in 3 trials) or stroke alone (in 2 trials). Patent foramen ovale closure reduced the primary end point (0.70 vs 1.48 events per 100 patient-years; risk ratio [RR], 0.52 [0.29-0.91]; I 2  = 55.0%) and stroke/transient ischemic attack (1.04 vs 2.00 events per 100 patient-years; RR, 0.55 [0.37-0.82]; I 2  = 42.2%) with modest heterogeneity compared with medical therapy. Procedural bleeding was not different between study arms (1.8% vs 1.8%; RR, 0.94 [0.49-1.83]; I 2  = 29.2%), but new-onset atrial fibrillation/flutter was increased with patent foramen ovale closure (6.6% vs 0.7%; RR, 4.69 [2.17-10.12]; I 2  = 29.3%). In patients with recent cryptogenic stroke, patent foramen ovale closure reduces recurrent stroke/transient ischemic attack compared with medical therapy, but is associated with a higher risk of new-onset atrial fibrillation/flutter.

    Noncoronary forms of atherosclerosis (including transient ischemic attacks or stroke of carotid origin or >50% stenosis of the carotid artery) are associated with a 10-year vascular risk of >20% and are considered as a coronary heart disease (CHD) -risk equivalent from the standpoint of lipid management. The Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) trial included patients with stroke or transient ischemic attack and no known CHD regardless of the presence of carotid atherosclerosis. We evaluated the risk of developing clinically recognized CHD in SPARCL patients. A total of 4731 patients (mean age, 63 years) was randomized to 80 mg/day atorvastatin placebo. The rates of major coronary event, any CHD event, and any revascularization procedure were evaluated. After 4.9 years of follow-up, the risks of a major coronary event and of any CHD end point in the placebo group were 5.1% and 8.6%, respectively. The rate of outcome of stroke decreased over time, whereas the major coronary event rate was stable. Relative to those having a large vessel-related stroke at baseline, those having a transient ischemic attack, hemorrhagic stroke, small vessel stroke, or a stroke of unknown cause had similar absolute rates for a first major coronary event and for any CHD event; transient ischemic attack, small vessel, and unknown cause groups had lower absolute revascularization procedure rates. Major coronary event, any CHD event, and any revascularization procedure rates were similarly reduced in all baseline stroke subtypes in the atorvastatin arm compared with placebo with no heterogeneity between groups. CHD risk can be substantially reduced by atorvastatin therapy in patients with recent stroke or transient ischemic attack regardless of stroke subtype.

    The knowledge, attitudes, and beliefs of key policy influencers and the general public can support or hinder the development of public policies that support cancer prevention. To address gaps in knowledge concerning healthy public policy development, views on cancer causation and endorsement of policy alternatives for cancer prevention among government influencers (elected members of legislative assemblies and senior ministry bureaucrats), non-governmental influencers (school board chairs and superintendents, print media editors and reporters, and workplace presidents and senior human resource managers), and the general public were compared. Two structured surveys, one administered to a convenience sample of policy influencers (government and non-governmental) and the other to a randomly selected sample of the general public, were used. The aim of these surveys was to understand knowledge, attitudes, and beliefs regarding health promotion principles and the priority and acceptability of policy actions to prevent four behavioral risk factors for cancer (tobacco use, alcohol misuse, unhealthy eating, and physical inactivity). Surveys were administered in Alberta and Manitoba, two comparable Canadian provinces. Although all groups demonstrated higher levels of support for individualistic policies (e.g., health education campaigns) than for fiscal and legislative measures, the general public expressed consistently greater support than policy influencers for using evidence-based policies (e.g., tax incentives or subsidies for healthy behaviors). These results suggest that Canadian policy influencers may be less open that the general public to adopt healthy public policies for cancer prevention, with potential detriment to cancer rates.

    Atherosclerosis is one of the main mechanisms of stroke and cardiovascular diseases and is associated with increased risk of recurrent stroke and cardiovascular events. Intima-medial thickness (IMT) is a well-known surrogate marker of atherosclerosis and has been used to predict stroke and cardiovascular events. However, the clinical significance of IMT and IMT change in stroke has not been investigated in well-designed studies. The PreventIon of CArdiovascular events in iSchemic Stroke patients with high risk of cerebral hemOrrhage-Intima-Media Thickness (PICASSO-IMT) sub-study is designed to investigate the effects of cilostazol, probucol, or both on IMT in patients with stroke. PICASSO-IMT is a prospective sub-study of the PICASSO study designed to measure IMT and plaque score at 1, 13, 25, 37, and 49 months after randomization. The primary outcome is the change in mean carotid IMT, which is defined as the mean of the far-wall IMTs of the right and left common carotid arteries, between baseline and 13 months after randomization. PICASSO-IMT will provide the largest IMT data set in a stroke population and will provide valuable information about the clinical significance of IMT in patients with ischemic stroke.

    Oral anticoagulation is recommended for stroke prevention in intermediate/high stroke risk atrial fibrillation (AF) patients. The objective of this study was to demonstrate the usefulness of analytic software tools for descriptive analyses of disease management in atrial AF; a secondary objective is to demonstrate patterns of potential anticoagulant undertreatment in AF. Retrospective data analyses were performed using the Anticoagulant Quality Improvement Analyzer (AQuIA), a software tool designed to analyze health plan data. Two-year data from five databases were analyzed: IMS LifeLink (IMS), MarketScan Commercial (MarketScanCommercial), MarketScan Medicare Supplemental (MarketScanMedicare), Clinformatics™ DataMart, a product of OptumInsight Life Sciences (Optum), and a Medicaid Database (Medicaid). Included patients were ≥ 18 years old with a new or existing diagnosis of AF. The first observed AF diagnosis constituted the index date, with patient outcomes assessed over a one year period. Key study measures included stroke risk level, anticoagulant use, and frequency of International Normalized Ratio (INR) monitoring. High stroke risk (CHADS2 ≥ 2 points) was estimated in 54% (IMS), 22% (MarketScanCommercial), 64% (MarketscanMedicare), 42% (Optum) and 62% (Medicaid) of the total eligible population. Overall, 35%, 29%, 38%, 39% and 16% of all AF patients received an anticoagulant medication in IMS, MarketScanCommercial, MarketScanMedicare, Optum and Medicaid, respectively. Among patients at high risk for stroke, 19% to 51% received any anticoagulant. The AQuIA provided a consistent platform for analysis across multiple AF populations with varying baseline characteristics. Analyzer results show that many high-risk AF patients in selected commercial, Medicare-eligible, and Medicaid populations do not receive appropriate thromboprophylaxis, as recommended by treatment guidelines.

    Anticoagulation using vitamin K antagonists (VKAs) significantly reduces the risk of recurrent stroke in stroke patients with atrial fibrillation (AF) and is recommended by guidelines. The German Competence NETwork on Atrial Fibrillation established a nationwide prospective registry including 9,574 AF patients, providing the opportunity to analyse AF management according to German healthcare providers. On enrolment, 896 (9.4 %) patients reported a prior ischaemic stroke or transient ischaemic attack. Stroke patients were significantly older, more likely to be female, had a higher rate of cardiovascular risk factors, and more frequently received anticoagulation (almost exclusively VKA) than patients without prior stroke history. Following enrolment, 76.4 % of all stroke patients without VKA contraindications received anticoagulation, which inversely associated with age (OR 0.95 per year; 95 % CI 0.92-0.97). General practitioners/internists (OR 0.40; 95 % CI 0.21-0.77) and physicians working in regional hospitals (OR 0.47; 95 % CI 0.29-0.77) prescribed anticoagulation for secondary stroke prevention less frequently than physicians working at university hospitals (reference) and office-based cardiologists (OR 1.40; 95 % CI 0.76-2.60). The impact of the treating healthcare provider was less evident in registry patients without prior stroke. In the AFNET registry, anticoagulation for secondary stroke prevention was prescribed in roughly three-quarters of AF patients, a significantly higher rate than in primary prevention. We identified two factors associated with withholding oral anticoagulation in stroke survivors, namely higher age and-most prominently-treatment by a general practitioner/internist or physicians working at regional hospitals.

    Because primary prevention of stroke is a priority, our aim was to assess the primary preventive potential of major lifestyle risk factors for stroke in middle-aged women and men. Among 23,927 persons, 551 (195 women and 356 men) had a first diagnosis of stroke during an average follow-up of 12.7 years. Using Cox proportional hazards models, we estimated the associations of adiposity, smoking, physical activity, alcohol consumption, and diet with risk of developing stroke. A competing risk model built from cause-specific proportional hazards models accounting for concurrent risk of death was used to calculate relative and absolute reductions in stroke occurrences that could have been achieved by maintaining a healthy lifestyle pattern. Obesity, smoking, alcohol consumption, diet, and physical inactivity were each identified as modifiable lifestyle risk factors for stroke. About 38% of stroke cases were estimated as preventable through adherence to a healthy lifestyle profile (never smoking, maintaining optimal body mass index and waist circumference, performing physical exercise, consuming a moderate quantity of alcohol, and following a healthy dietary pattern). Age-specific estimates of 5-year incidence rates for stroke in the actual cohort and in a hypothetical, comparable cohort of individuals following a healthy lifestyle would be reduced from 153 to 94 per 100,000 women and from 261 to 161 per 100,000 men for the age group 60 to 65 years. Our analysis confirms the strong primary prevention potential for stroke based on avoidance of excess body weight, smoking, heavy alcohol consumption, unhealthy diet, and physical inactivity. © 2014 American Heart Association, Inc.

    Abstract Background: Intervention strategies to reduce obesity include policy and environmental changes that are designed to provide opportunities, support, and cues to help people develop healthier behaviors. Policy changes at the state level are one way to influence access, social norms, and opportunities for better nutrition and increased physical activity among the population. Methods: Ten states were selected for a broad variance in obesity rates and number of enacted obesity prevention policies during the years of 2006–2009. Within the selected states, a purely qualitative study of attitudes of childhood obesity policy using semistructured telephone interviews was conducted. Interviews were conducted with state policy makers who serve on public health committees. A set of six states that had more than eight childhood obesity policies enacted were selected for subsequent qualitative interviews with a convenience sample of well-established advocates. Results: Policy makers in states where there was more childhood obesity policy action believed in the evidence behind obesity policy proposals. Policy makers also varied in the perception of obesity as a constituent priority. The major differences between advocates and policy makers included a disconnect in information dissemination, opposition, and effectiveness of these policies. Conclusions: The findings from this study show differences in perceptions among policy makers in states with a greater number of obesity prevention bills enacted. There are differences among policy makers and advocates regarding the role and effectiveness of state policy on obesity prevention. This presents an opportunity for researchers and practitioners to improve communication and translation of evidence to policy makers, particularly in states with low legislation. PMID:22799551

    Until now, industry and government stakeholders have dominated public discourse about policy options for obesity. While consumer involvement in health service delivery and research has been embraced, methods which engage consumers in health policy development are lacking. Conflicting priorities have generated ethical concern around obesity policy. The concept of 'intrusiveness' has been applied to policy decisions in the UK, whereby ethical implications are considered through level of intrusiveness to choice; however, the concept has also been used to avert government regulation to address obesity. The concept of intrusiveness has not been explored from a stakeholder's perspective. The aim is to investigate the relevance of intrusiveness and autonomy to health policy development, and to explore consensus on obesity policy priorities of under-represented stakeholders. The Policy-Delphi technique will be modified using the James Lind Alliance approach to collaborative priority setting. A total of 60 participants will be recruited to represent three stakeholder groups in the Australian context: consumers, public health practitioners and policymakers. A three-round online Policy-Delphi survey will be undertaken. Participants will prioritise options informed by submissions to the 2009 Australian Government Inquiry into Obesity, and rate the intrusiveness of those proposed. An additional round will use qualitative methods in a face-to-face discussion group to explore stakeholder perceptions of the intrusiveness of options. The novelty of this methodology will redress the balance by bringing the consumer voice forward to identify ethically acceptable obesity policy options. Ethical approval was granted by the Bond University Health Research Ethics Committee. The findings will inform development of a conceptual framework for analysing and prioritising obesity policy options, which will be relevant internationally and to ethical considerations of wider public health issues

    Currently, in some countries occupational health and safety policy and practice have a bias toward secondary prevention and workers' compensation rather than primary prevention. Particularly, in emerging economies, research has not adequately contributed to effective interventions and improvements in workers' health. This article, using South Africa as a case study, describes a methodology for identifying candidate fiscal policy interventions and describes the policy interventions selected for occupational health and safety. It is argued that fiscal policies are well placed to deal with complex intersectoral health problems and to focus efforts on primary prevention. A major challenge is the lack of empirical evidence to support the effectiveness of fiscal policies in improving workers' health. A second challenge is the underprioritization of occupational health and safety partly due to the relatively small burden of disease attributed to occupational exposures. Both challenges can and should be overcome by (i) conducting policy-relevant research to fill the empirical gaps and (ii) reconceptualizing, both for policy and research purposes, the role of work as a determinant of population health. Fiscal policies to prevent exposure to hazards at work have face validity and are thus appealing, not as a replacement for other efforts to improve health, but as part of a comprehensive effort toward prevention.

    Recent studies reveal deficiencies in stroke awareness and knowledge of risk factors among women. Existing stroke education interventions may not address common and sex-specific risk factors in the population with the highest stroke-related rate of mortality. This pilot study assessed the efficacy of a technology-enhanced, sex-specific educational program ("SISTERS") for women's knowledge of stroke. This was an experimental pretest-posttest design. The sample consisted of 150 women (mean age, 55 years) with at least 1 stroke risk factor. Participants were randomized to either the intervention (n = 75) or control (n = 75) group. Data were collected at baseline and at a 2-week posttest. There was no statistically significant difference in mean knowledge score (P = .67), mean confidence score (P = .77), or mean accuracy score (P = .75) between the intervention and control groups at posttest. Regression analysis revealed that older age was associated with lower knowledge scores (P women may have less comfort with technology and require consideration for cognitive differences.

    Full Text Available It is known that non-rheumatic atrial fibrillation (AF is one of the most common types of cardiac arrhythmia and a common cause of cardiogenic cerebral embolism. Oral anticoagulant therapy is a leader in the prevention of thromboembolic events in AF. More than 60 years, only warfarin and other vitamin K antagonists (VKA were used as oral therapy due to their extraordinary efficacy in preventing stroke and other thromboembolic events after myocardial infarction in AF and prosthetic heart valves. In addition, there are numerous problems associated with treatment with VKA, which significantly limits their widespread use. New anticoagulants, such as the oral direct thrombin inhibitor (dabigatrana etexilate and the direct factor Xa antagonists rivaroxaban, apixaban, edoxaban, have been recently designed, clinically tested, and put into practice. The initiation of clinical use of these agents has opened up a new page of oral anticoagulant therapy in the prevention of thromboembolic events in AF.

    Real-world data are a well-recognized component within the drug lifecycle, and such data are generated from a range of sources and study designs, including claims databases, electronic health records, non-interventional studies (NIS) and registries. While this information can be of vital clinical importance, there may be challenges in understanding the relevance of the differing study designs, endpoints and populations. Here, we summarize the value of real-world evidence and considerations pertinent to their use in clinical research. Owing to the variety of analyses being conducted using real-world data, it is important for researchers and clinicians to have a clear understanding of the nature and origin of those data, and to ensure they are valid, reliable and robust in terms of extrapolating meaningful findings. There are crucial questions to address when evaluating real-world studies, and we introduce a checklist to meet these objectives. In addition to advice for appraising data quality and study designs, several updates will be covered from real-world studies of rivaroxaban for stroke prevention in patients with atrial fibrillation (AF): the nationwide Danish cohort study, U.S. Department of Defense Military Health System database, retrospective claim database study REAFFIRM and a pooled analysis from the global NIS XArelto on preveNtion of sTroke and non-central nervoUS system systemic embolism in patients with non-valvular atrial fibrillation (XANTUS). Real-world studies consistently show that rivaroxaban is an effective treatment option with acceptable safety when used for stroke prevention in a large number of patients with AF across the globe.

At this time, the most effective long-term solution to protect patients from stroke and thromboembolism is oral anticoagulation, either with vitamin K antagonists (VKAs or a novel oral anticoagulant (NOAC. Despite the significant benefits they confer, both VKAs and NOACs are underused because of their increased potential for bleeding, and VKAs are underused because of their narrow therapeutic range, need for regular international normalized ratio checks, and interactions with food or medications. In patients with nonvalvular AF, approximately 90% of strokes originate from the left atrial appendage (LAA; in patients with rheumatic mitral valve disease, many patients (60% have strokes that originate from the left atrium itself. Surgical LAA amputation or closure, although widely used to reduce stroke risk in association with cardiac surgery, is not currently performed as a stand-alone operation for stroke risk reduction because of its invasiveness. Percutaneous LAA closure, as an alternative to anticoagulation, has been increasingly used during the last decade in an effort to reduce stroke risk in nonvalvular AF. Several devices have been introduced during this time, of which one has demonstrated noninferiority compared with warfarin in a randomized controlled trial. This review describes the

    The natural product totarol, a phenolic diterpenoid and a major constituent isolated from the sap of Podocarpus totara, has been reported to have a potent antimicrobial activity. In this study, we determined whether totarol possessed an additional neuroprotective activity in vitro and in vivo. We found that totarol prevented glutamate- and oxygen and glucose deprivation-induced neuronal death in primary rat cerebellar granule neuronal cells and cerebral cortical neurons. Totarol increased Akt and GSK-3β phosphorylation, Nrf2 and heme oxygenase-1 (HO-1) protein expressions and suppressed oxidative stress by increasing GSH and SOD activities. The PI3K/Akt inhibitor LY294002 prevented totarol neuroprotective effect by suppressing the totarol-induced changes in HO-1 expression and the activities of GSH and SOD. The HO-1 inhibitor ZnPPIX also prevented totarol-increased GSH and SOD activities. In a model of acute cerebral ischemic injury in Sprague–Dawley rats, produced by occlusion of the middle cerebral artery for 2 h followed by 22 h or 46 h of reperfusion, totarol significantly reduced infarct volume and improved the neurological deficit. In this model, totarol increased HO-1 expression and the activities of GSH and SOD. These observations suggest that totarol may be a novel activator of the Akt/HO-1 pathway protecting against ischemic stroke through reduction of oxidative stress. - Graphical abstract: It is unknown whether the natural product totarol has neuroprotective effects in vitro and in vivo. This study underscores that totarol prevents neuronal injury in vitro, not only by activating PI3K/Akt pathway, but also via induction of Nrf2, HO-1, GSH and SOD expressions. Totarol also ameliorated acute cerebral ischemic injury in a rat ischemic stroke model. The findings highlight that totarol may be exploited for protecting against ischemic stroke through Akt/HO-1 pathway. - Highlights: • Totarol protects glutamate- and OGD-induced neuronal injury in vitro.

    Uncertainty remains about the efficacy of folic acid therapy for the primary prevention of stroke because of limited and inconsistent data. To test the primary hypothesis that therapy with enalapril and folic acid is more effective in reducing first stroke than enalapril alone among Chinese adults with hypertension. The China Stroke Primary Prevention Trial, a randomized, double-blind clinical trial conducted from May 19, 2008, to August 24, 2013, in 32 communities in Jiangsu and Anhui provinces in China. A total of 20,702 adults with hypertension without history of stroke or myocardial infarction (MI) participated in the study. Eligible participants, stratified by MTHFR C677T genotypes (CC, CT, and TT), were randomly assigned to receive double-blind daily treatment with a single-pill combination containing enalapril, 10 mg, and folic acid, 0.8 mg (n = 10,348) or a tablet containing enalapril, 10 mg, alone (n = 10,354). The primary outcome was first stroke. Secondary outcomes included first ischemic stroke; first hemorrhagic stroke; MI; a composite of cardiovascular events consisting of cardiovascular death, MI, and stroke; and all-cause death. During a median treatment duration of 4.5 years, compared with the enalapril alone group, the enalapril-folic acid group had a significant risk reduction in first stroke (2.7% of participants in the enalapril-folic acid group vs 3.4% in the enalapril alone group; hazard ratio [HR], 0.79; 95% CI, 0.68-0.93), first ischemic stroke (2.2% with enalapril-folic acid vs 2.8% with enalapril alone; HR, 0.76; 95% CI, 0.64-0.91), and composite cardiovascular events consisting of cardiovascular death, MI, and stroke (3.1% with enalapril-folic acid vs 3.9% with enalapril alone; HR, 0.80; 95% CI, 0.69-0.92). The risks of hemorrhagic stroke (HR, 0.93; 95% CI, 0.65-1.34), MI (HR, 1.04; 95% CI, 0.60-1.82), and all-cause deaths (HR, 0.94; 95% CI, 0.81-1.10) did not differ significantly between the 2 treatment groups.

    Low serum potassium is associated with stroke in populations with cardiovascular disease, hypertension, and diabetes mellitus but has not been studied in a mainly healthy population. We aimed to study the relation between serum potassium and incident stroke and mortality in the Malmö Preventive Project, a large cohort with screening in early mid-life and follow-up >25 years. Serum potassium measurements and covariates were available in 21 353 individuals (79% men, mean age 44 years). Mean follow-up time was 26.9 years for stroke analyses and 29.3 years for mortality analyses. There were 2061 incident stroke events and 8709 deaths. Cox regression analyses adjusted for multiple stroke risk factors (age, sex, height, weight, systolic blood pressure, fasting blood glucose, serum sodium, current smoking, prevalent diabetes mellitus, prevalent coronary artery disease, and treatment for hypertension) were fitted. There was an independent, linear association between serum potassium, per mmol/L increase, and both stroke (hazard ratio, 1.33; 95% confidence interval, 1.17-1.52; P stroke and intracerebral hemorrhage and in both hypertensive and normotensive subjects. Serum potassium, measured in early mid-life, was linearly associated with both incidence of ischemic stroke and intracerebral hemorrhage and all-cause mortality. An interaction with serum sodium implies that factors related to electrolyte balance and incident hypertension may be mediating factors. © 2017 American Heart Association, Inc.

    As overweight and obesity is a risk factor for chronic diseases, the development of environmental and healthy public policy interventions across multiple sectors has been identified as a key strategy to address this issue. In 2009, a survey was developed to assess the attitudes and beliefs regarding health promotion principles, and the priority and acceptability of policy actions to prevent obesity and chronic diseases, among key policy influencers in Alberta and Manitoba, Canada. Surveys were mailed to 1,765 key influencers from five settings: provincial government, municipal government, school boards, print media companies, and workplaces with greater than 500 employees. A total of 236 surveys were completed with a response rate of 15.0%. Findings indicate nearly unanimous influencer support for individual-focused policy approaches and high support for some environmental policies. Restrictive environmental and economic policies received weakest support. Obesity was comparable to smoking with respect to perceptions as a societal responsibility versus a personal responsibility, boding well for the potential of environmental policy interventions for obesity prevention. This level of influencer support provides a platform for more evidence to be brokered to policy influencers about the effectiveness of environmental policy approaches to obesity prevention. © 2014 The Obesity Society.

    Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with stroke, cognitive impairment, and cardiovascular death. Some predisposing factors - as aging, diabetes, hypertension - induce and maintain electrophysiological and ultrastructural remodeling that usually includes fibrosis. Interatrial conduction disturbances play a crucial role in the initiation of atrial fibrosis and in its associated complications. The diagnosis of interatrial blocks (IABs) is easy to perform using the surface ECG. IAB is classified as partial when the P wave duration is ≥120 ms, and advanced if the P wave also presents a biphasic pattern in II, III and aVF. IAB is very frequent in the elderly and, particularly in the case of the advanced type, is associated with AF, AF recurrences, stroke, and dementia. The anticoagulation in elderly patients at high risk of AF without documented arrhythmias is an open issue but recent data suggest that it might have a role, particularly in elderly patients with structural heart disease, high CHA 2 DS 2 VASc (Congestive heart failure/left ventricular dysfunction, Hypertension, Age ≥ 75 [doubled], Diabetes, Stroke [doubled] - Vascular disease, Age 65-74, and Sex category [female]), and advanced IAB. In this debate, we discuss the association of surface ECG IAB, a marker of atrial fibrosis, with AF and stroke. We also present the rationale that justifies further studies regarding anticoagulation in some of these patients.

    It remains controversial about the optimal treatment of adult hemorrhagic moyamoya disease (MMD). In this study, the authors performed a meta-analysis to determine whether surgical treatment of adult hemorrhagic MMD is superior to conservative treatment. A systematic search of the PubMed, EMBASE, and Cochrane Central databases was performed for articles published until May 2017. Randomized-controlled trials and cohort studies about the efficacy of surgical treatment and conservative treatment in patients with hemorrhagic MMD at 16 years of age or older were selected. Recurrent stroke incidence including hemorrhagic and ischemic events at the end of the follow-up period was calculated between the 2 groups with a 95% confidence interval (CI). A total of 3 articles (including 146 patients) were included in the meta-analysis. There were significant differences between the 2 groups when the authors compared the overall recurrent stroke rate at the end of the follow-up period. Surgical treatment significantly reduced the risk of stroke (risk ratio, 0.43; 95% CI, 0.24-0.76; P = 0.004). The current meta-analysis suggests that surgical treatment is better for conservative treatment in adult hemorrhagic MMD with recurrent stroke rate. Future studies are required to confirm this conclusion.

    Stroke is a major cause of mortality and disability worldwide. The main cause of stroke is atherosclerosis, and the most common risk factor for atherosclerosis is hypertension. Therefore, antihypertensive treatments are recommended for the prevention of stroke. Three angiotensin receptor blockers (ARBs), telmisartan, irbesartan and candesartan, inhibit the expression of the receptor for advanced glycation end-products (RAGE), which is one of the pleiotropic effects of these drugs. High mobility group box 1 (HMGB1) is the ligand of RAGE, and has been recently identified as a lethal mediator of severe sepsis. HMGB1 is an intracellular protein, which acts as an inflammatory cytokine when released into the extracellular milieu. Extracellular HMGB1 causes multiple organ failure and contributes to the pathogenesis of hypertension, hyperlipidemia, diabetes mellitus, atherosclerosis, thrombosis, and stroke. This is the first review of the literature evaluating the potential of three ARBs for the HMGB1-RAGE axis on stroke therapy, including prevention and acute treatment. This review covers clinical and experimental studies conducted between 1976 and 2013. We propose that ARBs, which inhibit the HMGB1/RAGE axis, may offer a novel option for prevention and acute treatment of stroke. However, additional clinical studies are necessary to verify the efficacy of ARBs. PMID:24065095

    Eating disorders and obesity are rising in prevalence and are problems of considerable public health significance. Prevailing treatments have a limited impact on public health because the disorders do not yield easily to intervention and because the treatments are costly and available to few. Shifting from a medical to a public health model argues for increased focus on both prevention and public policy. Research on prevention is in its early stages but must be aggressively pursued. Even less is known about policy, but recommendations are made to alter policy so that consumption of healthful foods increases, consumption of unhealthful foods decreases, and levels of physical activity are enhanced.

    The prevalence and cardiovascular risk factors control (CVRF) are determining to suffer a stroke and its relapse which arise the mortality and disability. To estimate the incidence of the first episode of ictus and describe the results in primary and secondary cardiovascular prevention. Observational and prospective study of a fix cohort of 130,649 people, 15-90-year-old assigned to participants centers between 01/04/2006 and 31/03/2008. Community based register. Analyses were performed with the use of time-to-event methods, included Cox's multivariate on survival, risk of it's relapse; the CVRF diagnosed and it's relative risk (RR); cardiovascular risk. 553 patients were enrolled (48,8% female), average age 73.3 ± 11.6 years with the first episode of stroke. After the episode, the hypertension (74.9% vs 88.7%), atrial fibrillation (9.9% vs 16%) and dislipemia (37.8% vs 49.8%) increased significantly as well its control. The 47% (95% CI = 42.8-51.2) of the cases had high risk of relapsing. In the 15.7% of the patients happened relapse of cardiovascular event, 48.3% of which were stroke. The main predictors variables were history of recurrent cardiovascular event (RR = 6.7; 95% CI = 2.2-21.7) and the aging (RR = 1,08; 95% CI = 1.01-1.2). The cardiovascular secondary prevention seems to be more effective both in CVRF's detection and its control and is extremely important to get better results of survival.

    To examine the efficiency of electrical stimulation in combination with Bobath techniques in the prevention of inferior and anterior shoulder subluxation in acute stroke patients. A prospective randomized controlled trial. Intensive care unit and inpatient clinics of neurology in a university hospital. Forty-eight patients with acute stroke, divided equally into control and study groups. Subjects in both groups were treated in accordance with the Bobath concept during the early hospitalization period. In addition to Bobath techniques, electrical stimulation was also applied to the supraspinatus muscle, mid and posterior portions of the deltoid muscle of patients in the study group. Two radiological methods were used to measure the horizontal, vertical and total asymmetry and vertical distance values of the shoulder joint. Motor functions of the arm were evaluated with the Motor Assessment Scale. The hospitalization period was 12.62 ± 2.24 days for the control group and 11.66 ± 1.88 days for the study group. Shoulder subluxation occurred in 9 (37.5%) subjects in the control group, whereas it was not observed in the study group. All shoulder joint displacement values were higher in the control group than in the study group (horizontal asymmetry P = 0.0001, vertical asymmetry P = 0.0001, total asymmetry P = 0.0001, vertical range P = 0.002). Application of electrical stimulation combined with the Bobath approach proved to be efficient in preventing inferior and anterior shoulder subluxation in the acute stages of stroke.

    Reilly, John J

    2012-07-01

    Prevention of obesity in childhood and adolescence remains a worthwhile and realistic goal, but preventive efforts have been beset by a number of problems, which are the subject of this review. The review draws on recent systematic reviews and evidence appraisals and has a United Kingdom (UK) perspective because there is a rich evidence base in the United Kingdom that may be helpful to obesity prevention researchers elsewhere. Recent evidence of a leveling off in child and adolescent obesity prevalence in some Western nations should not encourage the belief that the obesity prevention problem has been solved, although a better understanding of recent secular trends might be helpful for prevention strategy in future. An adequate body of evidence provides behavioral targets of preventive interventions, and there are frameworks for prioritizing these targets logically and models for translating them into generalizable interventions with a wide reach (e.g., school-based prevention interventions such as Planet Health). An improved understanding of the "energy gap" that children and adolescents experience would be helpful to the design of preventive interventions and to their tailoring to particular groups. In the United Kingdom, some recent etiological evidence has been taken as indicative of the need for paradigm shifts in obesity prevention, but this evidence from single studies has not been replicated, and paradigm shifts probably occur only rarely. Ensuring that the evidence base on etiology and prevention influences policy effectively remains one of the greatest challenges for childhood obesity researchers.

    To investigate the safety, feasibility, and efficacy of left atrial appendage occlusion (LAAO) with the AMPLATZER Cardiac Plug (ACP) for stroke prevention in patients with atrial fibrillation (AF). Data from consecutive patients treated in 22 centres were collected. A total of 1,047 patients were included in the study. Procedural success was 97.3%. There were 52 (4.97%) periprocedural major adverse events. Follow-up was complete in 1,001/1,019 (98.2%) of successfully implanted patients (average 13 months, total 1,349 patient-years). One-year all-cause mortality was 4.2%. No death at follow-up was reported as device-related. There were nine strokes (0.9%) and nine transient ischaemic attacks (0.9%) during follow-up. The annual rate of systemic thromboembolism was 2.3% (31/1,349 patient-years), which is a 59% risk reduction. There were 15 major bleedings (1.5%) during follow-up. The annual rate of major bleeding was 2.1% (28/1,349 patient-years), which is a 61% risk reduction. Patients with single LAAO on aspirin monotherapy or no therapy and longer follow-up had fewer cerebral and fewer bleeding events. In this multicentre study, LAAO with the ACP showed high procedural success and a favourable outcome for the prevention of AF-related thromboembolism. Modification in antithrombotic therapy after LAAO may result in reduction of bleeding events.

    This study analyzes the determinants of Whites' support for punitive and preventive crime policies. It focuses on the predictive power of beliefs about race as described by symbolic racism theory. A dataset with 849 White respondents from three waves of the Los Angeles County Social Survey was used. In order to assess the weight of racial factors in crime policy attitudes, the effects of a range of race-neutral attitude determinants were controlled for, namely individual and structural crime attributions, perceived seriousness of crime, crime victimization, conservatism and news exposure. Results show a strong effect of symbolic racism on both types of crime policies, and in particular on punitive policies. High levels of symbolic racism are associated with support for tough, punitive crime policies and with opposition to preventive policies. Sub-dimensions of symbolic racism qualified these relationships, by showing that internal symbolic racism (assessing perceived individual deficiencies of Blacks) was most strongly predictive of punitiveness, whereas external symbolic racism (denial of institutional discrimination) predicted opposition to structural remedies. On the whole, despite the effects of race-neutral factors, the impact of symbolic racism on policy attitudes was substantial. Thus, White public opinion on both punitive and preventive crime policies is at least partially driven by racial prejudice.

    Background South Africa has a significant violence problem. The exposure of girls and women to interpersonal violence is widespread, and the victimization of men, especially to severe and homicidal forms of aggression, is of considerable concern, with male homicide eight times the global rate. In the last two decades, there have been a plethora of South African policies to promote safety. However, indications suggest that the policy response to violence is not coherently formulated, comprehensive, or evenly implemented. Objective This study examines selected South African national legislative instruments in terms of their framing and definition of violence and its typology, vulnerable populations, and prevention. Design This study comprises a directed content analysis of selected legislative documents from South African ministries mandated to prevent violence and its consequences or tasked with the prevention of key contributors to violence. Documents were selected using an electronic keyword search method and analyzed independently by two researchers. Results The legislative documents recognized the high levels of violence, confirmed the prioritization of selected vulnerable groups, especially women, children, disabled persons, and rural populations, and above all drew on criminological perspectives to emphasize tertiary prevention interventions. There is a policy focus on the protection and support of victims and the prosecution of perpetrators, but near absent recognition of men as victims. Conclusions There is a need to broaden the policy framework from primarily criminological and prosecutorial perspectives to include public health contributions. It is likewise important to enlarge the conceptions of vulnerability to include men alongside other vulnerable groups. These measures are important for shaping and resourcing prevention decisions and strengthening primary prevention approaches to violence. PMID:26228996

    Post-stroke Depression, Obstructive sleep apnea (OSA) and Cognitive impairment ("DOC") are associated with greater mortality, worse recovery and poorer quality of life. Best practice recommendations endorse routine screening for each condition; yet, all are under-assessed, diagnosed and treated. We seek to determine the feasibility and validity of an integrated tool ("DOC" screen) to identify stroke clinic patients at high-risk of depression, OSA, and cognitive impairment. All consecutive new referrals to a regional Stroke Prevention Clinic who were English-speaking and non-aphasic were eligible to be screened. Time for screen completion was logged. DOC screen results were compared to the neuropsychological battery and polysomnogram assessments using a modified receiver operator characteristic and area under the curve analysis. Data is reported to conform to STARD guidelines. 1503 people were screened over 2 years. 89% of eligible patients completed the screen in 5 minutes or less (mean 4.2 minutes), less than half the time it takes to complete the Montreal Cognitive Assessment (MoCA). 437 people consented to detailed testing. Of those, 421 completed the Structured Clinical Interview for Depression within 3 months of screening, 387 completed detailed neuropsychological testing within 3 months, and 88 had overnight polysomnograms. Screening scores combined with demographic variables (age, sex, education, body mass index), had excellent validity compared to gold standard diagnoses: DOC-Mood AUC 0.90; DOC-Apnea AUC 0.80; DOC-Cog AUC 0.81. DOC screen scores can reliably categorize patients in to low-, intermediate- or high-risk groups for further action and can do so with comparable accuracy to more time-consuming screens. Systematic screening of depression, obstructive sleep apnea, and cognitive impairment in 5 minutes or less is feasible and valid in a high volume stroke clinic using the DOC screen. The DOC screen may facilitate improved identification and treatment

    Full Text Available This paper addresses two issues that are key to Mexico’s violence and crime prevention policy. The first part reviews how the prevention policy has been shaped over the past 10 years. In the second, the effects of Mexico’s Programa Nacional de Prevención del Delito (PRONAPRED, National Crime Prevention Programme is analysed using Propensity Score Matching. Using data at the municipal level and taking the homicide and gun-related injuries rates as output variables, we found that PRONAPRED only significantly affects the homicide rate; however, that effect is the opposite of what is expected. The results of this research show that, in order to achieve the intended results, violence and crime prevention policies in Mexico require significant changes.

    Suicide and mental disorders are a growing public health issue in Bhutan, due in part to a rapidly transitioning society. The burden of suicide has been recognized by the Royal Government of Bhutan and, as a result, it introduced the country's first ever national suicide-prevention plan in 2015. The 3-year action plan takes a holistic approach to making suicide-prevention services a top social priority, through strengthening suicide-prevention policies, promoting socially protective measures, mitigating risk factors and reaching out to individuals who are at risk of suicide or affected by incidents of suicide. This article documents Bhutan's policy and governance for addressing depression and suicide within the context of its national suicide-prevention strategy, examines progress and highlights lessons for future directions in suicide prevention. Since the endorsement of the 3-year action plan by the prime minister's cabinet, the implementation of suicide-prevention measures has been accelerated through a high-level national steering committee. Activities include suicide-prevention actions by sectors such as health, education, monastic communities and police; building capacity of gatekeepers; and improving the suicide information system to inform policies and decision-making. Suicide-prevention activities have become the responsibility of local governments, paving the way for suicide prevention as an integral mandate across sectors and at grass-root levels in the Kingdom of Bhutan.

    Objective Apathy, or lack of motivation for goal-directed activities, contributes to reduced engagement in and benefit from rehabilitation, impeding recovery from stroke. We examined the effects of strategy training, a behavioral intervention used to augment usual inpatient rehabilitation, on apathy symptoms over the first 6 months after stroke. Design Secondary analysis of randomized controlled trial. Setting Acute inpatient rehabilitation. Participants Participants with acute stroke who exhibited cognitive impairments (Quick Executive Interview Scores ≥ 3) and were admitted for inpatient rehabilitation were randomized to receive strategy training (n=15, one session per day, 5 days per week, in addition to usual inpatient rehabilitation) or reflective listening (n=15, same dose). Methods Strategy training sessions focused on participant-selected goals and participant-derived strategies to address these goals, using a global strategy training method (Goal-Plan-Do-Check). Reflective listening sessions focused on participant reflections on their rehabilitation goals and experiences, facilitated by open-ended questions and active listening skills (attending, following and responding). Main Outcome Measurements Trained raters blinded to group assignment administered the Apathy Evaluation Scale at study admission, 3 and 6 months. Data were analyzed with repeated measures fixed-effects models. Results Participants in both groups had similar subsyndromal levels of apathy symptoms at study admission (strategy training, M=25.79, SD=7.62; reflective listening, M=25.18, SD=4.40). A significant group by time interaction (F2,28 =3.61, p =.040) indicated that changes in apathy symptom levels differed between groups over time. The magnitude of group differences in change scores was large (d=−0.99, t28=−2.64, p=.013) at month 3, and moderate to large at month 6 (d=−0.70, t28=−1.86, p=.073). Conclusion Strategy training shows promise as an adjunct to usual rehabilitation

    People of African Caribbean descent have higher mortality rates from stroke than other ethnic groups. However, little is known about the prevalence of stroke risk factors in UK ethnic minority groups. We investigated the prevalence of these risk factors amongst African Caribbeans, black Africans and whites. A random sample of patients aged 45-74 registered with 16 general practices in south London was surveyed in 1995. Main outcome measures were: prevalence of hypertension, mean serum cholesterol, serum fibrinogen and glycosylated haemoglobin AIC. Logistic and linear regressions were used to determine ethnic differences in these measures. Hypertension was more prevalent in black Caribbeans (79.4%) and black Africans (71.6%) than in whites (54.3%) (p Africans had similar rates to black Caribbeans for these risk factors apart from lower triglvceride levels. These differences in risk factors may partially explain the high stroke mortality rates in black Caribbeans and black Africans compared to whites. There was little difference in prevalence of these risk factors between black Caribbean and black African groups. Specific strategies targeted to each ethnic group need to be developed to reduce risk factors.

  3. Rationale for ischemic conditioning to prevent stroke in patients with intracranial arterial stenosis

    2016-01-01

    Full Text Available Intracranial atherosclerotic arterial stenosis (ICAS is one of the most common causes of stroke worldwide and is associated with particularly a high risk of recurrent stroke. Although aggressive medical management, consisting of dual antiplatelet therapy and intensive control of vascular risk factors, has improved the prognosis of patients with ICAS, subgroups of patients remain at very high risk of stroke. More effective therapies for these high-risk patients are urgently needed. One promising treatment is remote limb ischemic conditioning, which involves producing repetitive, transient ischemia of a limb by inflating a blood pressure cuff with the intention of protecting the brain from subsequent ischemia. In this study, we review the limitations of currently available treatments, discuss the potential mechanisms of action of ischemic conditioning, describe the preclinical and clinical data suggesting a possible role of ischemic conditioning in treating patients with ICAS, and outline the questions that still need to be answered in future studies of ischemic conditioning in subjects with ICAS.

    Damage-associated molecular patterns (DAMPs) trigger sterile inflammation after tissue injury, but the mechanisms underlying the resolution of inflammation remain unclear. In this study, we demonstrate that common DAMPs, such as high-mobility-group box 1 (HMGB1), peroxiredoxins (PRXs), and S100A8 and S100A9, were internalized through the class A scavenger receptors MSR1 and MARCO in vitro. In ischemic murine brain, DAMP internalization was largely mediated by MSR1. An elevation of MSR1 levels in infiltrating myeloid cells observed 3 d after experimental stroke was dependent on the transcription factor Mafb. Combined deficiency for Msr1 and Marco, or for Mafb alone, in infiltrating myeloid cells caused impaired clearance of DAMPs, more severe inflammation, and exacerbated neuronal injury in a murine model of ischemic stroke. The retinoic acid receptor (RAR) agonist Am80 increased the expression of Mafb, thereby enhancing MSR1 expression. Am80 exhibited therapeutic efficacy when administered, even at 24 h after the onset of experimental stroke. Our findings uncover cellular mechanisms contributing to DAMP clearance in resolution of the sterile inflammation triggered by tissue injury.

    Full Text Available The aim of this study was to reduce the door-to-needle (DTN time of intravenous thrombolysis (IVT in acute ischemic stroke (AIS through a comprehensive, hospital-based implementation strategy. The intervention involved a systemic literature review, identifying barriers to rapid IVT treatment at our hospital, setting target DTN time intervals, and building an evolving model for IVT candidate selection. The rate of non-in-hospital delay (DTN time ≤ 60 min was set as the primary endpoint. A total of 348 IVT cases were enrolled in the study (202 and 146 in the pre- and post-intervention group, respectively. The median age was 61 years in both groups; 25.2% and 26.7% of patients in the pre- and post-intervention groups, respectively, were female. The post-intervention group had higher rates of dyslipidemia and minor stroke [defined as National Institutes of Health Stroke Scale (NIHSS ≤ 3]; less frequent atrial fibrillation; higher numbers of current smokers, heavy drinkers, referrals, and multi-model head imaging cases; and lower NIHSS scores and blood sugar level (all P 0.05. These findings indicate that it is possible to achieve a DTN time ≤ 60 min for up to 60% of hospitals in the current Chinese system, and that this logistical change can yield a notable improvement in the outcome of IVT patients.

    The repair-bottleneck problem as a limiting factor for system reliability can be overcome. Design need only cover the steady state, wearout induced accumulations of failures being precluded by preventive replacements with subsequent recycling. As a result, a reliable system appears to be feasible on an economic basis, optimization in detail to be left to more precised cost-benefit studies. As a reference system the radio-frequency-generator cascade of a single-cell linear accelerator is considered. (DG)

    The growing resistance of Plasmodium falciparum to sulfadoxine-pyrimethamine (SP) treatment for uncomplicated malaria led to a recommendation by the World Health Organization for the use of artemisinin-based combination therapy. Inevitably, concerns were also raised surrounding the use of SP for intermittent prevention treatment of malaria during pregnancy (IPTp) amidst the lack of alternative drugs. Malawi was the first country to adopt intermittent prevention treatment with SP in 1993, and updated in 2013. This case study examines the policy updating process and the contribution of research and key stakeholders to this process. The findings support the development of a malaria research-to-policy framework in Malawi. Documents and evidence published from 1993 to 2012 were systematically reviewed in addition to key informant interviews. The online search identified 170 potential publications, of which eight from Malawi met the inclusion criteria. Two published studies from Malawi were instrumental in the WHO policy recommendation which in turn led to the updating of national policies. The updated policy indicates that more than two SP doses, as informed by research, overcome the challenges of the first policy of two SP doses only because of ineffectiveness by P. falciparum resistance and the global lack of replacement drugs to SP for IPTp. International WHO recommendations facilitated a smooth policy change driven by motivated local leadership with technical and financial support from development partners. Policy development and implementation should include key stakeholders and use local malaria research in a research-to-policy framework.

    Models are introduced and examined for the optimum scheduling of preventive replacements. The “replace first” and “replace last” models are known from the literature if the long term expected cost per unit time is minimized. We will first introduce the one cycle counterparts of these models when the expected costs per unit time in a single cycle is minimized. If the unit performs identical projects sequentially then the “replace next” model assumes that the preventive replacement is postponed until the ongoing project is finished. The termination time of this project is random which also depends on the scheduled time of the preventive replacement in contrary to the “replace first” and “replace last” models. The mathematical models are formulated and conditions are given for the existence of finite optima. Numerical examples and a simulation study illustrate the methodology and the numerical results show interesting comparisons of the different models. - Highlights: • The Single cycle age replacement model is extended incorporating repairable failures. • In order to avoid project interruption costs, three model variants are discussed. • Model variants are replace first, replace last and replace next. • In many cases analytic solutions are derived and illustrated by numerical examples. • The different model variants and their results are compared based on simulation studies.

    Identification of neuroprotective therapies in acute ischemic stroke is imperative. We report a predefined analysis of the URICO-ICTUS trial (Efficacy Study of Combined Treatment With Uric Acid and r-tPA in Acute Ischemic Stroke) assessing the efficacy of uric acid (UA) compared with placebo to prevent early ischemic worsening (EIW) and the relevance of collateral circulation. URICO-ICTUS was a double-blind, placebo-controlled, phase 2b trial where a total of 411 patients treated with alteplase within 4.5 hours of stroke onset were randomized (1:1) to receive UA 1000 mg (n=211) or placebo (n=200) before the end of alteplase infusion. EIW defined an increment ≥4 points in the National Institutes of Health Stroke Scale score within 72 hours of treatment in the absence of hemorrhage or recurrent stroke. Logistic regression models assessed the interaction between therapy and the collateral circulation in 112 patients who had a pretreatment computed tomographic angiography. EIW occurred in 2 of 149 (1%) patients with good outcome and 23 of 262 (9%) patients with poor outcome (χ 2 ; P=0.002). EIW occurred in 7 of 204 (3%) patients treated with UA and in 18 of 200 (9%) patients treated with placebo (χ 2 ; P=0.01). There was a significant interaction between the efficacy of UA to prevent EIW and collaterals (P=0.029), with lower incidence in patients with good collaterals treated with UA compared with placebo (2% versus 15%, respectively; P=0.048). UA therapy may prevent EIW after acute stroke in thrombolysed patients. Optimal access of UA to its molecular targets through appropriate collaterals may modify the magnitude of the neuroprotective effect. URL: http://www.clinicaltrials.gov.

    2008-06-05

    As obesity prevention becomes an increasing health priority in many countries, including Australia and New Zealand, the challenge that governments are now facing is how to adopt a systematic policy approach to increase healthy eating and regular physical activity. This article sets out a structure for systematically identifying areas for obesity prevention policy action across the food system and full range of physical activity environments. Areas amenable to policy intervention can be systematically identified by considering policy opportunities for each level of governance (local, state, national, international and organisational) in each sector of the food system (primary production, food processing, distribution, marketing, retail, catering and food service) and each sector that influences physical activity environments (infrastructure and planning, education, employment, transport, sport and recreation). Analysis grids are used to illustrate, in a structured fashion, the broad array of areas amenable to legal and regulatory intervention across all levels of governance and all relevant sectors. In the Australian context, potential regulatory policy intervention areas are widespread throughout the food system, e.g., land-use zoning (primary production within local government), food safety (food processing within state government), food labelling (retail within national government). Policy areas for influencing physical activity are predominantly local and state government responsibilities including, for example, walking and cycling environments (infrastructure and planning sector) and physical activity education in schools (education sector). The analysis structure presented in this article provides a tool to systematically identify policy gaps, barriers and opportunities for obesity prevention, as part of the process of developing and implementing a comprehensive obesity prevention strategy. It also serves to highlight the need for a coordinated approach to

    2012-01-01

    Background Policies targeting obesogenic environments and behaviours are critical to counter rising obesity rates and lifestyle-related non-communicable diseases (NCDs). Policies are likely to be most effective and enduring when they are based on the best available evidence. Evidence-informed policy making is especially challenging in countries with limited resources. The Pacific TROPIC (Translational Research for Obesity Prevention in Communities) project aims to implement and evaluate a tailored knowledge-brokering approach to evidence-informed policy making to address obesity in Fiji, a Pacific nation challenged by increasingly high rates of obesity and concomitant NCDs. Methods The TROPIC project draws on the concept of ‘knowledge exchange’ between policy developers (individuals; organisations) and researchers to deliver a knowledge broking programme that maps policy environments, conducts workshops on evidence-informed policy making, supports the development of evidence-informed policy briefs, and embeds evidence-informed policy making into organisational culture. Recruitment of government and nongovernment organisational representatives will be based on potential to: develop policies relevant to obesity, reach broad audiences, and commit to resourcing staff and building a culture that supports evidence-informed policy development. Workshops will increase awareness of both obesity and policy cycles, as well as develop participants’ skills in accessing, assessing and applying relevant evidence to policy briefs. The knowledge-broking team will then support participants to: 1) develop evidence-informed policy briefs that are both commensurate with national and organisational plans and also informed by evidence from the Pacific Obesity Prevention in Communities project and elsewhere; and 2) collaborate with participating organisations to embed evidence-informed policy making structures and processes. This knowledge broking initiative will be evaluated via

    To identify the proportion of real-life patients with atrial fibrillation (AF) eligible for direct oral anticoagulant (DOAC) therapy, based on the inclusion and exclusion criteria used in the clinical studies and based on the officially approved indications as mentioned in the Summary of Product Characteristics (SmPC). Data for this retrospective cross-sectional study was extracted from the UZ Brussel Stroke Registry, containing anonymized data of 2205 patients with a suspected stroke. Characteristics of patients with documented AF were compared with the patient characteristics in clinical trials and the approved indications in the SmPC. Data of 468 patients with AF was analyzed. Based on the selection criteria of the clinical trials, significantly less patients were eligible for treatment with rivaroxaban compared to dabigatran etexilate (39.3 versus 47.6 %; p = 0.010), but not compared to apixaban (45.5 %; p = 0.055). Based on the indications and contraindications in the SmPC, significantly fewer patients were eligible for apixaban compared to dabigatran etexilate and rivaroxaban (62.0 % for apixaban, 72.9 % for dabigatran etexilate, and 75.6 % for rivaroxaban; p trials (72.9 versus 47.6 %; p trials with DOACs for stroke prevention in AF, less than half of real-life patients are eligible for therapy with one of the DOACs. However, the indications mentioned in the SmPCs of these drugs are less strict.

    Addressing childhood obesity in Latin America requires a package of multisectoral, evidence-based policies that enable environments conducive to healthy lifestyles. Identify and examine key elements to translating research into effective obesity policies in Latin America. We examined obesity prevention policies through case studies developed with an expert in the specific policy. Policies were selected based on their level of implementation, visibility and potential impact to reduce childhood obesity. They include: (i) excise taxes on sugar sweetened beverages and energy-dense foods; (ii) front-of-package food label legislation; (iii) trans fatty acids removal from processed foods; and (iv) Ciclovías recreativas or 'open streets'. Case studies were coded to identify components that explained successful implementation and sustainability using the Complex Adaptive Health Systems framework. The analysis identified key elements for effective and sustainable policy, including evidence justifying policy; evidence-based advocacy by civil society; political will; and legislation and skillful negotiations across government, academia, the private sector and civil society. Scientific evidence and evaluation played an important role in achieving tipping points for policies' launch and sustain effective implementation. Well-coordinated, intersectoral partnerships are needed to successfully implement evidence-based anti-obesity policies. Prospective policy research may be useful for advancing knowledge translation. © 2017 The Authors. Obesity Reviews published by John Wiley & Sons Ltd on behalf of World Obesity.

    Full Text Available The last ten years have seen rapid strides in the evolution of nonvitamin K oral anticoagulants (NOACs for stroke prevention in patients with atrial fibrillation (AF. For the preparation of this consensus, a comprehensive literature search was performed and data on available trials, subpopulation analyses, and case reports were analyzed. This Indian consensus document intends to provide guidance on selecting the right NOAC for the right patients by formulating expert opinions based on the available trials and Asian/Indian subpopulation analyses of these trials. A section has been dedicated to the current evidence of NOACs in the Asian population. Practical suggestions have been formulated in the following clinical situations: (i Dose recommendations of the NOACs in different clinical scenarios; (ii NOACs in patients with rheumatic heart disease (RHD; (iii Monitoring anticoagulant effect of the NOACs; (iv Overdose of NOACs; (v Antidotes to NOACs; (vi Treatment of hypertrophic cardiomyopathy (HCM with AF using NOACs; (vii NOACs dose in elderly, (viii Switching between NOACs and vitamin K antagonists (VKA; (ix Cardioversion or ablation in NOAC-treated patients; (x Planned/emergency surgical interventions in patients currently on NOACs; (xi Management of bleeding complications of NOACs; (xii Management of acute coronary syndrome (ACS in AF with NOACs; (xiii Management of acute ischemic stroke while on NOACs.

    Oral anticoagulants reduce the incidence of stroke by 68%, yet suboptimal use has been documented in surveys of patients with atrial fibrillation. The present study examined current patterns of anticoagulant use for patients hospitalized with atrial fibrillation across an entire health care system. Improving Cardiovascular Outcomes in Nova Scotia (ICONS) is a prospective cohort study involving all patients hospitalized in Nova Scotia with atrial fibrillation, among other conditions. Consecutive inpatients with atrial fibrillation from October 15, 1997 to October 14, 1998 were studied. Detailed demographic and clinical data were collected and the proportion of patients using antithrombotic therapy was tabulated by risk category. Multivariate logistic regression was used to assess the relationship of various demographic and clinical factors with the use of antithrombotic agents. There were 2202 patients hospitalized with atrial fibrillation; 644 admitted specifically for this condition. Only 21% of patients admitted with atrial fibrillation were on warfarin sodium at admission and this increased by time of discharge. Diabetes was negatively correlated with warfarin sodium use. Histories of prosthetic valve replacement, stroke/transient ischemic attack, and heart failure were positively associated with anticoagulant use on admission. Patients with prosthetic valve replacement, heart failure, or hyperlipidemia were most likely to receive anticoagulants at discharge. Antithrombotic agents remain underused by patients with atrial fibrillation. While higher risk patients are generally targeted, this is not invariably the case; thus, diabetics remain under treated. Further work is needed to explain such anomalous practice and promote optimal antithrombotic therapy use.

    2015-01-01

    Background A study was conducted to investigate home health care agency central line–associated bloodstream infection (CLABSI) definitions and prevention policies and compare them to the Joint Commission National Patient Safety Goal (NPSG.07.04.01), the Centers for Disease Control and Prevention (CDC) CLABSI prevention recommendations, and a best-practice central line care bundle for inpatients. Methods A telephone-based survey was conducted in 2011 of a convenience sample of home health care agencies associated with children’s hematology/oncology centers. Results Of the 97 eligible home health care agencies, 57 (59%) completed the survey. No agency reported using all five aspects of the National Healthcare and Safety Network/Association for Professionals in Infection Control and Epidemiology CLABSI definition and adjudication process, and of the 50 agencies that reported tracking CLABSI rates, 20 (40%) reported using none. Only 10 agencies (18%) had policies consistent with all elements of the inpatient-focused NPSG.07.04.01, 10 agencies (18%) were consistent with all elements of the home care targeted CDC CLABSI prevention recommendations, and no agencies were consistent with all elements of the central line care bundle. Only 14 agencies (25%) knew their overall CLABSI rate: mean 0.40 CLABSIs per 1,000 central line days (95% confidence interval [CI], 0.18 to 0.61). Six agencies (11%) knew their agency’s pediatric CLABSI rate: mean 0.54 CLABSIs per 1,000 central line days (95% CI, 0.06 to 1.01). Conclusions The policies of a national sample of home health care agencies varied significantly from national inpatient and home health care agency targeted standards for CLABSI definitions and prevention. Future research should assess strategies for standardizing home health care practices consistent with evidence-based recommendations. PMID:23991509

    The objective of this study is to obtain the views of a sample of adolescents and experts on adolescence, family, school, local policies and media, regarding the effectiveness of institutional policies to prevent adolescent alcohol use. Four educational centers in the province of Seville. Head office of the Alcohol and Society Foundation in Madrid. Qualitative study using the method proposed by Grounded theory (Glaser and Strauss, 1967). Data were collected from 10 discussion groups guided by semistructured interviews. The data were analyzed using Atlas ti 5 software. A total of 32 national experts and 40 adolescents of both sexes aged 15 to 20 years living in the province of Seville, selected by theoretical intentional sampling. The experts believed that most of the evaluated preventive actions were effective, while adolescents disputed the preventive impact of most of them. Adolescents proposed actions focused on the reduction of supply of alcohol. Experts proposed a mixed model as the most effective strategy to prevent alcohol consumption in adolescents, combining supply and demand reduction policies, depending on specific short and long term objectives. We have obtained, not only an overview of what is working (or not) from the view of adolescents and experts, but also the key points that should be taken into account for designing effective prevention policies.

    The National Institute for Health and Clinical Excellence (NICE) invited the manufacturer of dabigatran etexilate (Boehringer Ingelheim Ltd, UK) to submit evidence for the clinical and cost-effectiveness of this drug for the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (AF) as part of the NICE single technology appraisal process. The Centre for Reviews and Dissemination and the Centre for Health Economics at the University of York were commissioned to act as the evidence review group (ERG). This article presents a summary of the manufacturer's submission, the ERG report and the subsequent development of NICE guidance for the use of dabigatran within the UK National Health Service. Dabigatran was granted marketing authorisation by the European Medicines Agency for a sequential dosing regimen (DBG sequential), in which patients under 80 years are treated with dabigatran 150 mg twice daily (DBG150) and patients 80 years and over are given dabigatran 110 mg twice daily (DBG110). NICE decisions are bound by the marketing authorisation; therefore, the decision problem faced by the committee was whether the DBG sequential regimen was effective and cost-effective compared with warfarin or aspirin for patients with non-valvular AF and one or more risk factors. The RE-LY trial, a large multi-centre non-inferiority randomised clinical trial, was the primary source of clinical evidence. DBG150 was shown to be non-inferior, and subsequently superior to warfarin, for the primary outcome of all stroke/systemic embolism. DBG110 was found to be non-inferior to warfarin. Results were presented for a post hoc subgroup analysis for patients under and over 80 years of age, where DBG110 showed a statistically significant reduction of haemorrhagic stroke and intracranial haemorrhage in comparison to warfarin in patients over 80 years of age. This post hoc subgroup analysis by age was the basis for the licensed DBG sequential regimen

    Having previously reported that comprehensive cardiac rehabilitation (CCR) is effective for secondary prevention post-transient ischemic attack (TIA)/mild nondisabling stroke (MNDS), we present psychometric findings for the same sample that elucidate subacute TIA/MNDS psychological outcomes and test whether CCR would be independently associated with psychological improvements. In this prospective cohort trial patients with ≥1 risk factor, recruited from a stroke prevention clinic within 12 months (mean = 11.5 weeks) post-TIA/MNDS, entered CCR. Of the 110 recruited patients, 100 (mean age = 65.4 years; 46 females) entered CCR and 80 completed CCR (mean duration = 7.6 months). At CCR entry, 16.5% and 39.2% screened positively for depression and anxiety, decreasing nonsignificantly at exit to 4.2%, and significantly to 16.9% (P = .008), respectively. Age-corrected deficits occurred more frequently than expected (P ≤ .03); at entry, mental health status (13.3%), clock-drawing (31.6%), oral-verbal fluency (16.9%), word-list learning (11.2%), and recall (12.6%); at exit, clock-drawing (30.0%). Entry-to-exit, mean depression, anxiety, mental and physical health status, word-list learning, memory, digit-symbol coding, and oral-verbal fluency scores improved significantly (P ≤ .031). No reliable change indices were significant. Psychological service recipients improved significantly more than nonrecipients in depression (P = .049). Baseline North American Adult Reading Test score predicted exercise attendance (R = 0.275; P = .044); New York Heart Association (NYHA) class and depression score predicted exit physical health status (R = 0.770, P psychological improvements. CCR psychological treatment may benefit depression. Subacute NYHA class and depression may later affect quality of life.

    We examined the effectiveness of preventive interventions against occupational injuries (preferential action plans [PAPs]) developed by Spanish regional governments starting in 2000. We included 3,252,028 occupational injuries with sick leave due to mechanical causes occurring between 1994 and 2004 in manufacturing and private service companies. Time trends for occupational injury rates were estimated before and after implementation of PAPs in each region, with a control group defined for those regions in which no PAPs were implemented (e.g., Galicia, Madrid, and Cataluña). We determined annual change percentages and their 95% confidence intervals (CIs) through a negative binomial regression model. Regions were grouped into three categories according to formal quality of their PAPs. The regions with the best PAPs (Andalucia, Aragon, Valencia, and Murcia) showed annually increasing occupational injury rates (2.3%, 95% CI -2.5, 7.4) before implementation of PAPs. After PAPs were implemented, occupational injury rates decreased significantly to -7.4% (95% CI -10.2, -4.5). Similar results were also found for regions with PAPs of lower quality and even for regions that didn't implement a PAP (control group). These results did not vary substantially in stratified analysis by gender, age, type of contract, or length of sick leave. PAPs are not related to a general decline in occupational injury rates in Spain starting in 2000. Reinforcement of Spanish health and safety regulations and labor inspection activities since 2000, resulting from a social agreement between central government and social agents, remains an alternative hypothesis requiring additional research.

    Policy-makers throughout the world seek to address childhood obesity prevention, yet little is known about factors that influence policy-makers' decisions on this topic. From September 2014 to April 2015, we conducted 43 semi-structured interviews about factors that encourage and discourage policy-makers' support for childhood obesity prevention policies. We interviewed policy-makers (n = 12) and two other groups engaged with childhood obesity prevention policies: representatives of non-governmental organizations (n = 24) and academics (n = 7). Factors that encourage policy-makers' support for childhood obesity prevention policies included: positive impact on government finances, an existing evidence base, partnerships with community-based collaborators, and consistency with policy-makers' priorities. Factors that discourage policy-makers' support included the following: perceptions about government's role, food and beverage industry opposition, and policy-makers' beliefs about personal responsibility. As public health practitioners, advocates, and others seek to advance childhood obesity prevention in the U.S. and elsewhere, the factors we identified offer insights into ways to frame proposed policies and strategies to influence policy-makers.

    Full Text Available Abstract Background The purpose of this research is to develop and evaluate methods for conducting pragmatic cluster randomized trials in a primary care electronic database. The proposal describes one application, in a less frequent chronic condition of public health importance, secondary prevention of stroke. A related protocol in antibiotic prescribing was reported previously. Methods/Design The study aims to implement a cluster randomized trial (CRT using the electronic patient records of the General Practice Research Database (GPRD as a sampling frame and data source. The specific objective of the trial is to evaluate the effectiveness of a computer-delivered intervention at enhancing the delivery of stroke secondary prevention in primary care. GPRD family practices will be allocated to the intervention or usual care. The intervention promotes the use of electronic prompts to support adherence with the recommendations of the UK Intercollegiate Stroke Working Party and NICE guidelines for the secondary prevention of stroke in primary care. Primary outcome measure will be the difference in systolic blood pressure between intervention and control trial arms at 12-month follow-up. Secondary outcomes will be differences in serum cholesterol, prescribing of antihypertensive drugs, statins, and antiplatelet therapy. The intervention will continue for 12 months. Information on the utilization of the decision-support tools will also be analyzed. Discussion The CRT will investigate the effectiveness of using a computer-delivered intervention to reduce the risk of stroke recurrence following a first stroke event. The study will provide methodological guidance on the implementation of CRTs in electronic databases in primary care. Trial registration Current Controlled Trials ISRCTN35701810

    European animal disease policy seems to find its justification in a “harm to other” principle. Limiting the freedom of animal keepers—e.g., by culling their animals—is justified by the aim to prevent harm, i.e., the spreading of the disease. The picture, however, is more complicated.

    Full Text Available There is an increasing research interest in targeting interventions at the neighborhood level to prevent obesity. Healthy urban environments require including residents’ perspectives to help understanding how urban environments relate to residents’ food choices and physical activity levels. We describe an innovative community-driven process aimed to develop environmental recommendations for obesity prevention. We conducted this study in a low-income area in Madrid (Spain, using a collaborative citizen science approach. First, 36 participants of two previous Photovoice projects translated their findings into policy recommendations, using an adapted logical framework approach. Second, the research team grouped these recommendations into strategies for obesity prevention, using the deductive analytical strategy of successive approximation. Third, through a nominal group session including participants, researchers, public health practitioners and local policy-makers, we discussed and prioritized the obesity prevention recommendations. Participants identified 12 policy recommendations related to their food choices and 18 related to their physical activity. The research team grouped these into 11 concrete recommendations for obesity prevention. The ‘top-three’ ranked recommendations were: (1 to adequate and increase the number of public open spaces; (2 to improve the access and cost of existing sports facilities and (3 to reduce the cost of gluten-free and diabetic products.

    The use of adaptive designs has been increasing in randomized clinical trials. Sample size re-estimation is a type of adaptation in which nuisance parameters are estimated at an interim point in the trial and the sample size re-computed based on these estimates. The Secondary Prevention of Small Subcortical Strokes study was a randomized clinical trial assessing the impact of single- versus dual-antiplatelet therapy and control of systolic blood pressure to a higher (130-149 mmHg) versus lower (size re-estimation was performed during the Secondary Prevention of Small Subcortical Strokes study resulting in an increase from the planned sample size of 2500-3020, and we sought to determine the impact of the sample size re-estimation on the study results. We assessed the results of the primary efficacy and safety analyses with the full 3020 patients and compared them to the results that would have been observed had randomization ended with 2500 patients. The primary efficacy outcome considered was recurrent stroke, and the primary safety outcomes were major bleeds and death. We computed incidence rates for the efficacy and safety outcomes and used Cox proportional hazards models to examine the hazard ratios for each of the two treatment interventions (i.e. the antiplatelet and blood pressure interventions). In the antiplatelet intervention, the hazard ratio was not materially modified by increasing the sample size, nor did the conclusions regarding the efficacy of mono versus dual-therapy change: there was no difference in the effect of dual- versus monotherapy on the risk of recurrent stroke hazard ratios (n = 3020 HR (95% confidence interval): 0.92 (0.72, 1.2), p = 0.48; n = 2500 HR (95% confidence interval): 1.0 (0.78, 1.3), p = 0.85). With respect to the blood pressure intervention, increasing the sample size resulted in less certainty in the results, as the hazard ratio for higher versus lower systolic blood pressure target approached, but did not

    Chen, Stephanie C; Pearson, Steven D

    2016-08-01

    The US Affordable Care Act mandates that private insurers cover a list of preventive services without cost sharing. The list is determined by 4 expert committees that evaluate the overall health effect of preventive services. We analyzed the process by which the expert committees develop their recommendations. Each committee uses different criteria to evaluate preventive services and none of the committees consider cost systematically. We propose that the existing committees adopt consistent evidence review methodologies and expand the scope of preventive services reviewed and that a separate advisory committee be established to integrate economic considerations into the final selection of free preventive services. The comprehensive framework and associated criteria are intended to help policy makers in the future develop a more evidence-based, consistent, and ethically sound approach.

  11. Policy statement--Role of the pediatrician in youth violence prevention.

    Science.gov (United States)

    2009-07-01

    Youth violence continues to be a serious threat to the health of children and adolescents in the United States. It is crucial that pediatricians clearly define their role and develop the appropriate skills to address this threat effectively. From a clinical perspective, pediatricians should become familiar with Connected Kids: Safe, Strong, Secure, the American Academy of Pediatrics' primary care violence prevention protocol. Using this material, practices can incorporate preventive education, screening for risk, and linkages to community-based counseling and treatment resources. As advocates, pediatricians may bring newly developed information regarding key risk factors such as exposure to firearms, teen dating violence, and bullying to the attention of local and national policy makers. This policy statement refines the developing role of pediatricians in youth violence prevention and emphasizes the importance of this issue in the strategic agenda of the American Academy of Pediatrics.

    2015-05-05

    Collagen type IV alpha1 (COL4A1) and alpha2 (COL4A2) form heterotrimers critical for vascular basement membrane stability and function. Patients with COL4A1 or COL4A2 mutations suffer from diverse cerebrovascular diseases, including cerebral microbleeds, porencephaly, and fatal intracerebral hemorrhage (ICH). However, the pathogenic mechanisms remain unknown, and there is a lack of effective treatment. Using Col4a1 and Col4a2 mutant mouse models, we investigated the genetic complexity and cellular mechanisms underlying the disease. We found that Col4a1 mutations cause abnormal vascular development, which triggers small-vessel disease, recurrent hemorrhagic strokes, and age-related macroangiopathy. We showed that allelic heterogeneity, genetic context, and environmental factors such as intense exercise or anticoagulant medication modulated disease severity and contributed to phenotypic heterogeneity. We found that intracellular accumulation of mutant collagen in vascular endothelial cells and pericytes was a key triggering factor of ICH. Finally, we showed that treatment of mutant mice with a US Food and Drug Administration-approved chemical chaperone resulted in a decreased collagen intracellular accumulation and a significant reduction in ICH severity. Our data are the first to show therapeutic prevention in vivo of ICH resulting from Col4a1 mutation and imply that a mechanism-based therapy promoting protein folding might also prevent ICH in patients with COL4A1 and COL4A2 mutations. © 2015 American Heart Association, Inc.

    Left atrial appendage occlusion (LAAO) using the Amplatzer cardiac plug (ACP) is a preventive treatment of atrial fibrillation related thromboembolism. To assess the safety and efficacy of LAAO in patients with chronic kidney disease (CKD). Among the ACP multicentre registry, 1014 patients (75±8yrs) with available renal function were included. Patients with CKD (N=375, CHA2DS2-VASc: 4.9±1.5, HASBLED: 3.4±1.3) were at higher risk than patients without CKD (N=639, CHA2DS2-VASc: 4.2±1.6, HASBLED: 2.9±1.2; p<0.001 for both). Procedural (97%) and occlusion (99%) success were similarly high in all stages of CKD. Peri-procedural major adverse events (MAE) were observed in 5.1% of patients, 0.8% of death, with no difference between patients with and those without CKD (6.1 vs 4.5%, p=0.47). In patients with complete follow-up (1319 patients years), the annual stroke+transient ischaemic attack (TIA) rate was 2.3% and the observed bleeding rate was 2.1% (62 and 60% less than expected, similarly among patients with and those without CKD). Kaplan-Meier analysis showed a lower overall survival (84 vs 96% and 84 vs 93% at 1 and 2yrs. respectively; p<0.001) among patients with an eGFR <30ml/min/1.73m(2). LAAO using the ACP has a similar procedural safety among CKD patients compared to patients with normal renal function. LAAO with ACP offers a dramatic reduction of stroke+TIA rate and of bleeding rate persistent in all stages of CKD, as compared to the expected annual risk. Copyright © 2016 Elsevier Ireland Ltd.

    2015-06-01

    Current obesity rates in young children are a serious public health concern; developing and implementing obesity prevention interventions in childcare settings is a promising avenue to address this issue. In recent years, there has been increasing focus on environmental and policy change interventions for this setting. Improving access to and quality of outdoor play spaces and implementing the Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC) are two promising environmental change strategies in this setting. Laws at the local, state, and federal level have also been implemented; New York City and Delaware are two jurisdictions that have passed policies and provided preliminary evidence of the potential of policy interventions to change child outcomes. A combination of programmatic, environmental, and policy change strategies will likely be most effective in maximizing the potential of childcare settings to promote healthy weight in children.

It is unknown how physicians make treatment decisions in primary stroke prevention for patients with AF. Objectives: To evaluate the association between family physicians’ risk preferences (aversion risk and ambiguity and therapeutic recommendations (anticoagulation in the management of AF for primary stroke prevention by applying concepts from behavioral economics. Methods: Overall, 73 family physicians participated and completed the study. Our study comprised seven simulated case vignettes, three behavioral experiments, and two validated surveys. Behavioral experiments and surveys incorporated an economic framework to determine risk preferences and biases (e.g., ambiguity aversion, willingness to take risks. The primary outcome was making the correct decision of anticoagulation therapy. Secondary outcomes included medical errors in the management of AF for stroke prevention. Results: Overall, 23.3% (17/73 of the family physicians elected not to escalate the therapy from antiplatelets to anticoagulation when recommended by best practice guidelines. A total of 67.1% of physicians selected the correct therapeutic options in two or more of the three simulated case vignettes. Multivariate

    Full Text Available Noncommunicable diseases and injuries account for 52% of deaths in India. Burden of noncommunicable diseases and resultant mortality is expected to increase unless massive efforts are made to prevent and control NCDs and their risk factors. Based on available evidence, cancer, diabetes, hypertension, cardiovascular diseases, stroke, chronic obstructive pulmonary disease, chronic kidney disease, mental disorders and trauma are the leading causes of morbidity, disability and mortality in India. Government of India had supported the States in prevention and control of NCDs through several vertical programs since 1980s. However, during the 11 th plan, there was considerable upsurge to prevent and control NCDs. New programs were started on a low scale in limited number of districts. However, there has not been any considerable change in the burden of NCDs. Based on experiences in the past, there is need to emphasize on health promotion and preventive measures to reduce exposure to risk factors. Facilities and capacity for screening, early diagnosis and effective management are required within the public health care system. Public awareness program, integrated management and strong monitoring system would be required for successful implementation of the program and making services universally accessible in the country.

    This paper presents a system dynamics policy model of nutritional food market transformation, tracing over-time interactions between the nutritional quality of supply, consumer food choice, population health, and governmental policy. Applied to the Canadian context and with body mass index as the primary outcome, we examine policy portfolios for obesity prevention, including (1) industry self-regulation efforts, (2) health- and nutrition-sensitive governmental policy, and (3) efforts to foster health- and nutrition-sensitive innovation. This work provides novel theoretical and practical insights on drivers of nutritional market transformations, highlighting the importance of integrative policy portfolios to simultaneously shift food demand and supply for successful and self-sustaining nutrition and health sensitivity. We discuss model extensions for deeper and more comprehensive linkages of nutritional food market transformation with supply, demand, and policy in agrifood and health/health care. These aim toward system design and policy that can proactively, and with greater impact, scale, and resilience, address single as well as double malnutrition in varying country settings. © 2014 New York Academy of Sciences.

    Recurrent strokes are preventable through awareness and control of risk factors such as hypertension, and through lifestyle changes such as healthier diets, greater physical activity, and smoking cessation. However, vascular risk factor control is frequently poor among stroke survivors, particularly among socio-economically disadvantaged blacks, Latinos and other people of color. The Chronic Care Model (CCM) is an effective framework for multi-component interventions aimed at improving care processes and outcomes for individuals with chronic disease. In addition, community health workers (CHWs) have played an integral role in reducing health disparities; however, their effectiveness in reducing vascular risk among stroke survivors remains unknown. Our objectives are to develop, test, and assess the economic value of a CCM-based intervention using an Advanced Practice Clinician (APC)-CHW team to improve risk factor control after stroke in an under-resourced, racially/ethnically diverse population. In this single-blind randomized controlled trial, 516 adults (≥40 years) with an ischemic stroke, transient ischemic attack or intracerebral hemorrhage within the prior 90 days are being enrolled at five sites within the Los Angeles County safety-net setting and randomized 1:1 to intervention vs usual care. Participants are excluded if they do not speak English, Spanish, Cantonese, Mandarin, or Korean or if they are unable to consent. The intervention includes a minimum of three clinic visits in the healthcare setting, three home visits, and Chronic Disease Self-Management Program group workshops in community venues. The primary outcome is blood pressure (BP) control (systolic BP control of other vascular risk factors including lipids and hemoglobin A1c, (3) inflammation (C reactive protein [CRP]), (4) medication adherence, (5) lifestyle factors (smoking, diet, and physical activity), (6) estimated relative reduction in risk for recurrent stroke or myocardial

    Atrial fibrillation (AF) is one of the leading causes of stroke. Risks associated with oral anticoagulation (OAC) limit adherence to recommended therapy. Left atrial appendage (LAA) occlusion is a treatment alternative in patients with AF. We performed a network meta-analysis (NMA) of randomized trials evaluating the efficacy of LAA occlusion compared with oral anticoagulant, antiplatelet, and placebo for stroke prevention. We also assessed the impact of LAA occlusion on mortality, major bleeding, and operative time. We searched MEDLINE, EMBASE, PubMed, and Cochrane Library for randomized trials comparing percutaneous or surgical LAA occlusion with standard of care in AF patients. Conventional meta-analysis found no difference between groups for stroke (5 trials, 1285 patients;RR 0.78, 95% CI 0.47-1.29), and a significant reduction in mortality (5 trials, 1285 patients; RR 0.71, 95% CI 0.51-0.99) favouring LAA occlusion. NMA demonstrated a trend towards reduction in stroke (OR 0.84, 95% CrI 0.47-1.55) and mortality (OR 0.69, 95% CrI 0.44-1.10) for LAA occlusion versus warfarin, but no statistically significant effect. Statistical ranking curves placed LAA occlusion as the most efficacious treatment on the outcomes of stroke and mortality when compared to warfarin, aspirin, or placebo. No significant differences between groups were seen in major bleeding or operative time for surgical trials. The overall quality of the evidence was low as assessed by GRADE. LAA occlusion appears to preserve the benefits of OAC therapy for stroke prevention in patients with AF, but the current evidence is of low quality.

  2. Accelerating Progress in Eating Disorders Prevention: A Call for Policy Translation Research and Training.

    Austin, S Bryn

    2016-01-01

    The public health burden of eating disorders is well documented, and over the past several decades, researchers have made important advances in the prevention of eating disorders and related problems with body image. Despite these advances, however, several critical limitations to the approaches developed to date leave the field far from achieving the large-scale impact that is needed. This commentary provides a brief review of what achievements in prevention have been made and identifies the gaps that limit the potential for greater impact on population health. A plan is then offered with specific action steps to accelerate progress in high-impact prevention, most compellingly by promoting a shift in priorities to policy translation research and training for scholars through the adoption of a triggers-to-action framework. Finally, the commentary provides an example of the application of the triggers-to-action framework as practiced at the Strategic Training Initiative for the Prevention of Eating Disorders, a program based at the Harvard T. H. Chan School of Public Health and Boston Children's Hospital. Much has been achieved in the nearly 30 years of research carried out for the prevention of eating disorders and body image problems, but several critical limitations undermine the field's potential for meaningful impact. Through a shift in the field's priorities to policy translation research and training with an emphasis on macro-environmental influences, the pace of progress in prevention can be accelerated and the potential for large-scale impact substantially improved.

    Full Text Available Using research grants administrators and their clients (academic researchers as the lens, this paper investigated the relevance and implication of a fraud prevention policy at a University of Technology (UoT in South Africa. The paper adopted a quantitative approach in which closed-ended questions were complemented by open-ended questions in the survey questionnaire in the attempt to capture the perceptions of both research grants administrators and their clients on the relevance and implications of a fraud and irregularity prevention policy. The results indicate that both research grants administrators (71.4 %, and their clients (73% do not know if UoTx has a fraud and irregularity policy. While only 36% of research grants administrators indicated that they would feel safe reporting deceitful activities, a slight majority (59% of the clients reported same. With regards to the steps to follow to report fraudulent activity, it was noted that while all (100% the research grants administrators noted that they were clueless, ironically an overwhelming majority of their clients indicated otherwise. Notwithstanding, both research grants administrators and their clients (93% and 95% respectively concurred that a fraud prevention policy was necessary for UoTx. The implication is that having phenomenal controls that are not effectively publicized, monitored or worse still overridden by someone are useless.

    This article presents a case study determining the optimal preventive maintenance policy for a light rail rolling stock system in terms of reliability, availability, and maintenance costs. The maintenance policy defines one of the three predefined preventive maintenance actions at fixed time-based intervals for each of the subsystems of the braking system. Based on work, maintenance, and failure data, we model the reliability degradation of the system and its subsystems under the current maintenance policy by a Weibull distribution. We then analytically determine the relation between reliability, availability, and maintenance costs. We validate the model against recorded reliability and availability and get further insights by a dedicated sensitivity analysis. The model is then used in a sequential optimization framework determining preventive maintenance intervals to improve on the key performance indicators. We show the potential of data-driven modelling to determine optimal maintenance policy: same system availability and reliability can be achieved with 30% maintenance cost reduction, by prolonging the intervals and re-grouping maintenance actions.

    The classification of an acute vascular episode, both heart infarct and stroke, as an accident at work poses difficulties not only for post accidental teams, but also to occupational health professionals, experts and judges at labor and social insurance courts. This article presents the case of a 41-year-old office worker, whose job involved client services. While attending a very aggressive customer she developed solid stress that resulted in symptoms of the central nervous system (headache, speech disturbances). During her hospitalisation at the neurological unit ischemic stroke with transient mixed type aphasia was diagnosed. Magnetic resonance imaging (MRI) scan of the head revealed subacute ischemia. After an analysis of the accident circumstances, the employer's post accidental team decided that ischemic stroke had been an accident at work, because it was a sudden incident due to an external cause inducing work-related traumatic stroke. As a primary cause tough stress and emotional strain due to the situation developed while attending the customer were acknowledged. During control medical check up after 5 months the patient was found to be fit for work, so she could return to work. However, it should be noted that such a check up examination of subjects returning to work after stroke must be holistic, including the evaluation of job predispositions and health education aimed at secondary prevention of heart and vascular diseases with special reference to their risk factors.

    Setting up a follow-up secondary prevention program after stroke is difficult due to motor and cognitive impairment, but necessary to prevent recurrence and improve patients' quality of life. To involve a referent nurse and a caregiver from the patient's social circle in nurse-led multimodal and long-term management of risk factors after stroke could be an advantage due to their easier access to the patient and family. The aim of this study is to compare the benefit of optimized follow up by nursing personnel from the vascular neurology department including therapeutic follow up, and an interventional program directed to the patient and a caregiving member of their social circle, as compared with typical follow up in order to develop a specific follow-up program of secondary prevention of stroke. The design is a randomized, controlled, clinical trial conducted in the French Stroke Unit of the Strokavenir network. In total, 410 patients will be recruited and randomized in optimized follow up or usual follow up for 2 years. In both group, patients will be seen by a neurologist at 6, 12 and 24 months. The optimized follow up will include follow up by a nurse from the vascular neurology department, including therapeutic follow up, and a training program on secondary prevention directed to the patient and a caregiving member of their social circle. After discharge, a monthly telephone interview, in the first year and every 3 months in the second year, will be performed by the nurse. At 6, 12 and 24 month, the nurse will give the patient and caregiver another training session. Usual follow up is only done by the patient's general practitioner, after classical information on secondary prevention of risk factors during hospitalization. The primary outcome measure is blood pressure measured after the first year of follow up. Blood pressure will be measured by nursing personnel who do not know the group into which the patient has been randomized. Secondary endpoints are

    School-based bullying and other forms of school violence have been the topic of over 40 years of research in the U.S. and internationally. Within the last 2 decades, research has increasingly informed bullying prevention, policy, and legislative efforts. The purpose of this article is to highlight several critical research areas on bullying and other forms of school violence that have shaped prevention efforts and policy over the last 2 decades. As the recipient of the 2016 Award for Distinguished Contributions to Research in Public Policy , the discussion here will focus largely on research findings from The Espelage Lab and collaborators, but these studies and findings will be situated in the larger literature. Topics covered include conceptualization of bullying from a social-ecological framework, developmental considerations of bullying and associated forms of aggression, identification of populations at heightened risk for bullying, and efficacy of bullying prevention programs. Recommendations are provided for the next generation of scholars, practitioners, and policymakers focused on bullying prevention. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    The treatment of ischaemic stroke with neuroprotective drugs has been unsuccessful, and whether these compounds can be used to reduce disability after recurrent stroke is unknown. The putative neuroprotective effects of antiplatelet compounds and the angiotensin II receptor antagonist telmisartan were investigated in the Prevention Regimen for Effectively Avoiding Second Strokes (PRoFESS) trial. Patients who had had an ischaemic stroke were randomly assigned in a two by two factorial design to receive either 25 mg aspirin (ASA) and 200 mg extended-release dipyridamole (ER-DP) twice a day or 75 mg clopidogrel once a day, and either 80 mg telmisartan or placebo once per day. The predefined endpoints for this substudy were disability after a recurrent stroke, assessed with the modified Rankin scale (mRS) and Barthel index at 3 months, and cognitive function, assessed with the mini-mental state examination (MMSE) score at 4 weeks after randomisation and at the penultimate visit. Analysis was by intention to treat. The study was registered with ClinicalTrials.gov, number NCT00153062. 20,332 patients (mean age 66 years) were randomised and followed-up for a median of 2.4 years. Recurrent strokes occurred in 916 (9%) patients randomly assigned to ASA with ER-DP and 898 (9%) patients randomly assigned to clopidogrel; 880 (9%) patients randomly assigned to telmisartan and 934 (9%) patients given placebo had recurrent strokes. mRS scores were not statistically different in patients with recurrent stroke who were treated with ASA and ER-DP versus clopidogrel (p=0.38), or with telmisartan versus placebo (p=0.61). There was no significant difference in the proportion of patients with recurrent stroke with a good outcome, as measured with the Barthel index, across all treatment groups. Additionally, there was no significant difference in the median MMSE scores, the percentage of patients with an MMSE score of 24 points or less, the percentage of patients with a drop in MMSE

Given its effectiveness and safety profile, the calcium channel blocker amlodipine is among the most frequently prescribed antihypertensive drugs. This analysis was conducted to determine the costs and quality-adjusted life years (QALYs associated with the use of amlodipine and valsartan, an angiotensin II receptor blocker, in preventing stroke and MI in Taiwanese hypertensive patients. A state transition (Markov model was developed to compare the 5-year costs and QALYs for amlodipine and valsartan. Effectiveness data were based on the NAGOYA HEART Study, local studies, and a published meta-analysis. Utility data and costs of MI and stroke were retrieved from the published literature. Medical costs were based on the literature and inflated to 2011 prices; drug costs were based on National Health Insurance prices in 2014. A 3% discount rate was used for costs and QALYs and a third-party payer perspective

    2017-01-01

    Objectives: Changes in policy can reduce violence and injury; however, little is known about how partnerships among organizations influence policy development, adoption, and implementation. To understand partnerships among organizations working on injury and violence prevention (IVP) policy, we examined IVP policy networks in 15 large US cities. Methods: In summer 2014, we recruited 15 local health departments (LHDs) to participate in the study. They identified an average of 28.9 local partners (SD = 10.2) working on IVP policy. In late 2014, we sent survey questionnaires to 434 organizations, including the 15 LHDs and their local partners, about their partnerships and the importance of each organization to local IVP policy efforts; 319 participated. We used network methods to examine the composition and structure of the policy networks. Results: Each IVP policy network included the LHD and an average of 21.3 (SD = 6.9) local partners. On average, nonprofit organizations constituted 50.7% of networks, followed by government agencies (26.3%), schools and universities (11.8%), coalitions (11.2%), voluntary organizations (9.6%), hospitals (8.5%), foundations (2.2%), and for-profit organizations (0.7%). Government agencies were perceived as important by the highest proportion of partners. Perceived importance was significantly associated with forming partnerships in most networks; odds ratios ranged from 1.07 (95% CI, 1.02-1.13) to 2.35 (95% CI, 1.68-3.28). Organization type was significantly associated with partnership formation in most networks after controlling for an organization’s importance to the network. Conclusions: Several strategies could strengthen local IVP policy networks, including (1) developing connections with partners from sectors that are not well integrated into the networks and (2) encouraging indirect or less formal connections with important but missing partners and partner types.

    Patients with atrial fibrillation (AF) have a high risk of stroke and mortality, which can be considerably reduced by oral anticoagulants (OAC). Recently, four non-vitamin-K oral anticoagulants (NOACs) were compared with warfarin in large randomized trials for the prevention of stroke and systemic embolism. Today's clinician is faced with the difficult task of selecting a suitable OAC for a patient with a particular clinical profile or a particular pattern of risk factors and concomitant diseases. We reviewed analyses of subgroups of patients from trials of vitamin K antagonists vs. NOACs for stroke prevention in AF with the aim to identify patient groups who might benefit from a particular OAC more than from another. In the first of a two-part review, we discuss the choice of NOAC for stroke prevention in the following subgroups of patients with AF: (i) stable coronary artery disease or peripheral artery disease, including percutaneous coronary intervention with stenting and triple therapy; (ii) cardioversion, ablation and anti-arrhythmic drug therapy; (iii) mechanical valves and rheumatic valve disease, (iv) patients with time in therapeutic range of >70% on warfarin; (v) patients with a single stroke risk factor (CHA2DS2VASc score of 1 in males, 2 in females); and (vi) patients with a single first episode of paroxysmal AF. Although there are no major differences in terms of efficacy and safety between the NOACs for some clinical scenarios, in others we are able to suggest that particular drugs and/or doses be prioritized for anticoagulation.

    Atrial fibrillation (AF) is an increasingly common cause of stroke and systemic embolism. While warfarin has been the mainstay of stroke prevention in patients with AF, newer novel oral anticoagulant medications are now available. Rivaroxaban, a direct factor Xa inhibitor with a rapid onset and offset after oral administration, offers potential advantages over warfarin, predominantly due to its predictable pharmacokinetics across wide patient populations. It requires no coagulation monitoring, and only two different doses are needed (20 mg daily for patients with normal renal function and 15 mg daily in those with reduced renal function). A large randomized trial (ROCKET AF) has shown non-inferiority to warfarin for preventing stroke or systemic embolism in the per-protocol population and superiority to warfarin in the on-treatment safety population. Several subanalyses confirm that the treatment effect of rivaroxaban is consistent across different patient subgroups, including those with reduced renal function. The tolerability of rivaroxaban appears similar to that of warfarin, with comparable overall bleeding rates in clinical trials. In ROCKET AF, significantly lower rates of fatal and intracranial bleeding were seen with rivaroxaban, while lower rates of gastrointestinal bleeding were seen with warfarin. Important contraindications to rivaroxaban include valvular AF, the presence of a prosthetic valve (mechanical or bioprosthetic) or valve repair, the need for concurrent dual antiplatelet therapy, and creatinine clearance <30 ml/min. Once-daily dosing and the lack of coagulation monitoring may increase utilization and adherence compared with warfarin, potentially decreasing the large burden of care associated with stroke secondary to AF. Overall, rivaroxaban offers a useful alternative to warfarin for stroke prevention in patients with AF.

    Stress ulcer is one ofacute stroke complications. Giving ranitidine or omeprazole may prevent stress ulcer, but may increase the occurrence of pneumonia. Thus, it will affect the outcome of acute stroke. The method was experimental with a randomized control-group pretest - posttest design. This study divided the subjects into two groups, ranitidine 300mg and omeprazole 20mg group.We observed the patients whether stress ulcer or pneumonia occurred during hospitalization. Then, we measured the outcome by the National Institutes of Health Stroke Scaleand modified Rankin Scale. There were 32 subjects in this study. Only 1 (3.1%) subject suffered stress ulcer, and 3 (3.1%) suffered pneumonia in ranitidine group. Moreover, 2 (6.2%) subjects suffered pneumonia in omeprazole group. The differences were not significant between the two groups (p = 0.31 and p = 0.54). There was no significant effect and difference effect on the administration of both medications to the outcome at day 14. These results indicate that ranitidine and omeprazole have anequal effectiveness in the prevention of stress ulcer and also have equal effect on the occurrence of pneumonia, and both have no effect on the outcome of acute stroke patients.

    Full Text Available BACKGROUND: Men who have sex with men (MSM are a high-risk group for HIV. Implementation of effective preventive activities is an important way to combat HIV among MSM. However, in Ukraine there is no real HIV prevention policy among MSM and the need for its formulation is still open. MATERIAL AND METHODS: Analysis of legal acts, national reports and other official documents related to HIV prevention among MSM was carried out for Romania, Slovenia, the Netherlands, and Sweden.RESULTS: European countries use various approaches to HIV prevention among MSM: institutional, structural, and media approach.Countries under consideration have fully specified the minimum standard package for HIV prevention among MSM, who are defined as the highest priority group. Distinct strategies for MSM and ways to achieve them are outlined within the national plans and strategies for combating HIV/AIDS (Slovenia, Romania, the Netherlands. The National plan for HIV prevention among MSM will come into action in 2012 in Sweden. Countries, chosen for this study, use the principle of social contract by which the government provides subsidies and grants to nongovernmental organizations (NGOs working with MSM through its specialized health care units (Slovenia, Sweden, and sometimes only for one national NGO (the Netherlands. Outreach is the most common model of NGO’s activities.. In Sweden, MSM can get counseling and HIV testing in specialized HIV clinic for MSM. HIV prevention among MSM is run by representatives of NGOs through dating sites (Slovenia, Romania, through educating MSM and further promotion of healthy lifestyles among their friends. Along with the behavior modification activities, anti-discrimination strategies are used (Sweden, the Netherlands, Slovenia.CONCLUSIONS: Review of the regulatory frameworks, empowerment of NGOs, implementation of the social contract mechanisms, using interactive tools and providing education for MSM can be key points of HIV

    Full Text Available The article considers main measures of the financial policy realised in the countries of the world, in particular, Europe, USA, China and Japan, directed at prevention and liquidation of consequences of crisis phenomena of the world economy. It considers programmes of support of economy and financial sector of different countries adopted during the period of the world financial crisis of 2007 – 2009. It marks out that an important element of successful realisation of anti-crisis measures is a correct co-ordination of the budget and tax policy and money and loan policy. It positively marks out experience of application of active arbitrary stimulating policy under crisis conditions. In view of increase of efficiency of macro-economic management an important task of the future would be improvement of anti-crisis mechanisms with consideration of their influence upon short-term dynamics and long-term growth. The conducted analysis allows making a conclusion that mistakes of the financial policy are one of the main reasons of overheating the world economy, while analysis and use of experience of the leading countries of the world would allow increase of quality of the financial policy, directed at reduction of crisis vulnerability.

    2017-04-01

    The field of prevention of body image problems and eating disorders has made major advances in recent years, particularly in the development and evaluation of prevention programmes. However, few programmes achieve good long-term results because, among other reasons, the sociocultural influences affecting the development of these problems do not stop. Moreover, accelerating progress in this field is required, transferring their impact onto a larger scale. These reasons justify the need to progress in the development of public policy interventions. This paper describes a recent Catalan initiative in this sphere: the Roundtable on the Prevention of Eating Disorders, made up of different public and private sectors of Catalan society. It specifically details the main actions carried out, such as: media campaigns to reduce weight-related teasing and encouraging self-esteem, encouraging family meals and promoting help-seeking among those affected; the creation of a new informative website about these matters in the Department of Health; the production of a Decalogue of Best Practices for the promotion of self-esteem and positive body image in social media and advertising; and actions to prevent the promotion of eating disorders on the Internet. The Roundtable is the most comprehensive Catalan (and Spanish) public policy activity undertaken until now for the prevention of eating disorders. Copyright © 2016 Elsevier Ltd. All rights reserved.

  5. Prevention-based approaches to social policy: The case of early childhood development

    Directory of Open Access Journals (Sweden)

    Alan Tapper

    2012-08-01

    Full Text Available This article reviews the Australian evidence concerning interventions in early childhood aimed at promoting children’s psychological well-being and preventing social and psychological dysfunction in later life. Two kinds of research are surveyed. One is the Australian social science literature that has emerged in the last twenty years from five major research programs. The other is the evaluation studies that, more recently, have assessed the effectiveness of various early childhood preventive interventions. Together these studies provide an evidentiary platform for reviewing current policy in this field. A full analysis of ‘what works’ would need to include relevant international evidence, which is outside the scope of this article. However, the Australian evidence does support the current policy focus on good parenting programs, while also suggesting that a number of other factors matter in promoting children’s well-being.

  8. A two-stage preventive maintenance policy for a multi-state deterioration system

    International Nuclear Information System (INIS)

    Huang, C.-C.; Yuan, John

    2010-01-01

    This paper is to propose a two-stage preventive maintenance (PM) policy for the multi-state deterioration system under periodic inspection and with multiple candidate actions for PM. Such policy is mainly to schedule PM optimally and also on how to choose the action optimally for each PM. The scheduling includes two tasks: to determine after completing each PM when to make the decision and then at it to schedule the next PM optimally. We assume that: (1) such actions except replacement are imperfect, (2) the inspection and action times can be ignored, (3) the system can be modeled by a multi-state discrete time Markov chain whose transition probabilities will change and be updated only at the instant after completing each PM, and (4) the risks of such imperfect actions will be updated only at the instant after completing each PM. Finally, an example through simulation is presented to illustrate how such policy can be carried out.

    The study analyses the framework conditions, such as the Non-Proliferation Treaty and the international non-proliferation regime and their interlacement with international nuclear energy policies, and evaluates the results achieved so far on an international level by the efforts directed towards preventing the proliferation of nuclear weapons. The conclusion to be drawn as stated by the author is that the classical tool of non-proliferation policy - denial of technology transfer - will lose in importance and give way to enhanced, controlled cooperation between countries of the Third World and the industrialised countries. Another instrument that will maintain its value for non-proliferation policy is cooperation for political stabilisation in those parts of the world where regional conflicts might aggravate.

  11. Searching for sustainability within public health policy: insights from an injury prevention perspective.

    Errington, Gail; Evans, Catrin; Watson, Michael C

    2017-04-01

    Sustaining public health programmes in the long-term is key to ensuring full manifestation of their intended benefits. Although an increasing interest in sustainability is apparent within the global literature, empirical studies from within the European setting are few. The factors that influence sustainability are generally conceptualized at three levels: programme level, the immediate context and the wider environment. To-date attention has focused primarily on the former two. Using a community-based child injury prevention programme in England as an exemplar, this paper explores the concept of sustainability within the wider policy environment, and considers the impact of this on local programmes. A content review of global and UK national public health policies (1981-2014) relevant to child safety was undertaken. Interviews were held with senior representatives of global and UK agencies involved in developing child safety policy. Forty-nine policies were reviewed. The term 'sustain', or its derivatives, featured in 36 (73%) of these. Its' use however, related primarily to conservation of resources rather than continued programme operation. Potential mechanisms for supporting programme sustainability featured within some documents; however, the approach to sustainability was inconsistent between policies and over time. Policy stakeholders identified programme sustainability as relevant to their core business, but its' conceptualization varied according to individual interpretation. Programme sustainability is poorly addressed within global and UK-based public health policy. Strengthening a national and international policy focus on sustainability and incorporating sustainability into public health planning frameworks may create a more supportive environment for local programmes. © The Author 2016.

    Problems related to high levels of gaming and Internet usage are increasingly recognized as a potential public health burden across the developed world. The aim of this review was to present an international perspective on prevention strategies for Internet gaming disorder and related health conditions (e.g., Internet addiction), as well as hazardous gaming and Internet use. A systematic review of quantitative research evidence was conducted, followed by a search of governmental reports, policy and position statements, and health guidelines in the last decade. The regional scope included the USA, UK, Australia, China, Germany, Japan, and South Korea. Prevention studies have mainly involved school-based programs to train healthier Internet use habits in adolescents. The efficacy of selective prevention is promising but warrants further empirical attention. On an international scale, the formal recognition of gaming or Internet use as a disorder or as having quantifiable harms at certain levels of usage has been foundational to developing structured prevention responses. The South Korean model, in particular, is an exemplar of a coordinated response to a public health threat, with extensive government initiatives and long-term strategic plans at all three levels of prevention (i.e., universal, selective, and indicated). Western regions, by comparison, are dominated by prevention approaches led by non-profit organizations and private enterprise. The future of prevention of gaming and Internet problems ultimately relies upon all stakeholders working collaboratively in the public interest, confronting the reality of the evidence base and developing practical, ethical, and sustainable countermeasures.

    The overall analysis of the rivaroxaban versus warfarin in Japanese patients with atrial fibrillation (J-ROCKET AF) trial revealed that rivaroxaban was not inferior to warfarin with respect to the primary safety outcome. In addition, there was a strong trend for a reduction in the rate of stroke/systemic embolism with rivaroxaban compared with warfarin. In this subanalysis of the J-ROCKET AF trial, we investigated the consistency of safety and efficacy profile of rivaroxaban versus warfarin among the subgroups of patients with previous stroke, transient ischemic attack, or non-central nervous system systemic embolism (secondary prevention group) and those without (primary prevention group). Patients in the secondary prevention group were 63.6% of the overall population of J-ROCKET AF. In the secondary prevention group, the rate of the principal safety outcome (% per year) was 17.02 in rivaroxaban-treated patients and 18.26 in warfarin-treated patients (hazard ratio [HR] 0.95; 95% confidence interval [CI] 0.70-1.29), while the rate of the primary efficacy endpoint was 1.66 in rivaroxaban-treated patients and 3.25 in warfarin-treated patients (HR 0.51; 95% CI 0.23-1.14). There were no significant interactions in the principal safety and the primary efficacy endpoints of rivaroxaban compared to warfarin between the primary and secondary prevention groups (P=.090 and .776 for both interactions, respectively). The safety and efficacy profile of rivaroxaban compared with warfarin was consistent among patients in the primary prevention group and those in the secondary prevention group.

    2015-07-01

    Full Text Available Background: The Scottish Government's ‘Route-Map Action Plan' for obesity prevention sets out 62 potential intervention policies across all stages of the life course. We used the ANGELO Framework (Analysis Grid for Environments Linked to Obesity to assess the appropriateness and likely impact of the balance of measures being proposed. Methods: Two assessors (JM & RJ independently allocated a category for each intervention according to its domain (physical, economic, legislative or socio-cultural, scale (macro or micro and predominant ‘focus' (physical activity versus diet. A third assessor (RG examined discordant allocations. Results: Across the four ANGELO domains, the distribution of interventions was skewed towards socio-cultural measures (37.1% and the physical environment (33.1% with less emphasis on legislative or economic interventions (21.8% and 6.4% respectively. Distribution by both intervention scale and focus was more even with just over half of all policies (51.8% at the macro-level scale and just under half (46.7% having a dietary focus. Conclusion: The predominance of socio-culturally orientated interventions over their legislative and economic counterparts is at odds with the balance of international evidence on what would be most effective for obesity prevention. The ANGELO framework provides a useful tool for policy makers to monitor progress towards an appropriately balanced policy mix.

    Neonatal hypernatremic dehydration is prevented by daily neonatal weight monitoring. We aim to provide evidence-based support of this universally promoted weighing policy and to establish the most crucial days of weighing. Weight measurements of 2,359 healthy newborns and of 271 newborns with clinical hypernatremic dehydration were used within the first seven days of life to simulate various weighting policies to prevent hypernatremic dehydration; its sensitivity, specificity and positive predictive value (PPV) of these policies were calculated. Various referral criteria were also evaluated. A policy of daily weighing with a cut-off value of -2.5 Standard Deviation Score (SDS) on the growth chart for weight loss, had a 97.6% sensitivity, 97.6% specificity and a PPV of 2.80%. Weighing at birth and only at days two, four and seven with the same -2.5 SDS cut-off, resulted in 97.3% sensitivity, 98.5% specificity and a PPV of 4.43%. A weighing policy with measurements restricted to birth and day two, four and seven applying the -2.5 SDS cut-off seems an optimal policy to detect hypernatremic dehydration. Therefore we recommend to preferably weigh newborns at least on day two (i.e. ~48h), four and seven, and refer them to clinical pediatric care if their weight loss increases below -2.5 SDS. We also suggest lactation support for the mother, full clinical assessment of the infant and weighing again the following day in all newborns reaching a weight loss below -2.0 SDS.

    Local, state, and national policies that limit the hours that alcoholic beverages may be available for sale might be a means of reducing excessive alcohol consumption and related harms. The methods of the Guide to Community Preventive Services were used to synthesize scientific evidence on the effectiveness of such policies. All of the studies included in this review assessed the effects of increasing hours of sale in on-premises settings (in which alcoholic beverages are consumed where purchased) in high-income nations. None of the studies was conducted in the U.S. The review team’s initial assessment of this evidence suggested that changes of less than 2 hours were unlikely to significantly affect excessive alcohol consumption and related harms; to explore this hypothesis, studies assessing the effects of changing hours of sale by less than 2 hours and by 2 or more hours were assessed separately. There was sufficient evidence in ten qualifying studies to conclude that increasing hours of sale by 2 or more hours increases alcohol-related harms. Thus, disallowing extensions of hours of alcohol sales by 2 or more should be expected to prevent alcohol-related harms, while policies decreasing hours of sale by 2 hours or more at on-premises alcohol outlets may be an effective strategy for preventing alcohol-related harms. The evidence from six qualifying studies was insufficient to determine whether increasing hours of sale by less than 2 hours increases excessive alcohol consumption and related harms. PMID:21084080

    We applied cluster analysis to identify discrete patterns of concomitant responses of systolic (SBP), diastolic (DBP) and pulse pressure (PP) during intensive BP lowering; and to evaluate their clinical relevance and association with risk of mortality, major vascular events (MVEs), and stroke. We used an unsupervised cluster procedure to identify distinct patterns of BP change during the first 9 months of anti-hypertensive therapy intensification among 1,331 participants in the Secondary Prevention of Small Subcortical Strokes Trial who were previously randomized to lower BP target (SBP < 130 mm Hg) after lacunar stroke. The cluster procedure partitioned participants into three groups in the lower SBP target arm, persons with: 1) mildly elevated baseline SBP and minimal visit-to-visit BP variability (mild reducers); 2) moderately elevated baseline SBP and moderate visit-to-visit BP variability (moderate reducers); and 3) very elevated baseline SBP with very large visit-to-visit BP variability during intensification (large reducers). In the lower SBP target group, moderate reducers had a higher risk of death (adjusted HR 1.6 [95% CI 1.0-2.7]), MVE (adjusted HR 2.1 [95% CI 1.4-3.2]), and stroke (adjusted HR 2.6[95% CI 1.7-4.1]) compared to mild reducers. Large reducers had the highest risk of death (adjusted HR 2.3 [95% CI 1.2-4.4]), but risk of MVE (HR = 1.7 [95%CI 0.9-3.1]) and stroke (HR = 1.6 [95%CI: 0.8-3.5]) were not statistically significantly different compared to mild reducers. Among persons with prior lacunar stroke, baseline BP levels, and BP variability in the setting of intensive BP lowering can identify discrete groups of persons at higher risk of adverse outcomes.

    Full Text Available The article’s objective is to determine the mechanism for implementing the financial instruments of the state policy to counter terrorist acts in the territory not controlled by Ukrainian authorities in Donetsk and Luhansk regions. Methodology. Within the scientific research, for the most effective approaches at the national level to prevent the threat of international terrorism, under the conditions of the deep internal political crisis and extremely difficult economic situation, in order to improve the efficiency of public administration in developing and implementing the anti-terrorism state policies in Ukraine, the paper analyses international and domestic regulations on preventing the terrorist financing, considers factors that affect the deterioration of the social and economic situation of the temporarily occupied parts of Donbas. Results of the research allow formulating the definition of financial instruments of antiterrorist policies, the paper develops and proposes a series of organizational measures in order to prevent the terrorist financing in Ukraine. Practical implications. Based on the above, we propose an option of classification of main illegal mechanisms that may be used to finance terrorist activities in the territories of Donetsk and Luhansk regions uncontrolled by Ukrainian authorities, dividing them into internal and external. Given the above studied factors and classification of financing of terrorist acts in eastern Ukraine, we can assume that for the purpose of evading duty payable to relevant state bodies of Ukraine, external supplies of inventories in the uncontrolled areas of the Donetsk region, which are later obtained by illegal armed groups, are possibly carried out as follows: on behalf of a commercial entity registered in a foreign country for the Ukrainian commercial entity, registered in settlements located in the uncontrolled territory; crossing of international transit traffic that moves through the

  20. The Politics of Prevention: Lessons from the Neglected History of US HIV/AIDS Policy.

    Science.gov (United States)

    Padamsee, Tasleem J

    2017-02-01

    The history of government action on HIV/AIDS has much to teach us about the dynamics and possibilities of US public health policy, but it has been insufficiently studied by social scientists of the epidemic. This article draws on a large set of original interviews with policy makers, thousands of news articles, and extensive documentation to reconstruct the history of three areas of debate and decision making about HIV prevention since 1990: needle exchange, HIV testing, and sex education for at-risk groups. These histories illuminate three key lessons. First, scientific evidence has less power to drive public health policy in the United States than in the United Kingdom, which is used as a comparison case to contextualize US choices within a broader range of options. Second, moral concerns weigh so heavily in the United States that a publicly articulated moral argument can countermand the dictates of solid scientific evidence, the voices of experts, and practical considerations to push public health policy in entirely oppositional directions. Third, having the ear of the presidential administration is usually a necessary-although not always sufficient-condition for the success of advocates trying to move US policy in the public health-indicated direction.

  1. On preventive maintenance policy of a critical reliability level for system subject to degradation

    International Nuclear Information System (INIS)

    Zhao, Y.X.

    2003-01-01

    Conventional preventive maintenance (PM) policies generally hold same time interval for PM actions and are often applied with known failure modes. The same time interval will give unavoidably decreasing reliabilities at the PM actions for degradation system with imperfect PM effect and the known failure modes may be inaccurate in practice. Therefore, field managers would prefer policy with an acceptable reliability level to keep system often at a good state. A PM policy with the critical reliability level is presented to address the preference of field managers. Through assuming that system after a PM action starts a new failure process, a parameter so-called degradation ratio is introduced to represent the imperfect effect. The policy holds a law that there is same number of failures in the time intervals of various PM cycles, and same degradation ratio for the system reliability or benefit parameters such as the optimal time intervals and the hazard rates between the neighboring PM cycles. This law is valid to any of the failure modes that could be appropriately referred as a 'general isodegrading model', and the degradation ratio as a 'general isodegrading ratio'. In addition, life cycle availability and cost functions are derived for system with the policy. An analysis of the field data of a loading and unloading machine indicates that the reliability, availability and cost in life cycle might be well modeled by the present theory and approach

    Metaphors can both inspire and mislead the public. Current metaphors for youth violence are inconsistent with scientific evidence about how chronic violence develops and evoke inaccurate or harmful reactions. Popular, problematic metaphors include superpredator, quarantining the contagious, corrective surgery, man as computer, vaccine, and chronic disease. Four new metaphors that more accurately reflect the science of child development are proposed to shape the field. Preventive dentistry offers a lifelong system of universal, selected, and indicated intervention policies. Cardiovascular disease offers concepts of distal risk factors, proximal processes, equifinality and multifinality, and long-term prevention. The Centers for Disease Control and Prevention's public health model focuses on injury and the victim to elicit popular support. Public education for illiteracy offers concepts of long-term universal education coupled with specialized help for high-risk youths and goes beyond metaphor to represent a truly applicable framework. Research is proposed to test the scientific merit for and public receptivity to these metaphors.

    Australian Aboriginal children are over-represented on all negative health indicators compared with non-Aboriginal children.Contributing factors to the disparity include the impact of historical events, racism and social determinants of health. Despite the benefits of child health checks, offered through the Medicare Benefit Schedule and community health services, uptake of these is low. In 2012, Western Australia Health implemented the Enhanced Aboriginal Child Health Schedule (EACHS) policy to address specific health needs of Aboriginal children. The Aboriginal Child Heath Project (the Project), was a five-year initiative funded through the Council of Australian Governments. Project staff promoted the profile of preventative child health and the uptake of the EACHS policy across the state by agencies operating in the sector. Western Australia. Reach of the implementation workshop was measured by the number of staff attending policy implementation and the total number for agencies represented. One measure of impact was the number of agencies requesting the EACHS policy who adapted or adopted it to deliver evidence based comprehensive child health programs. The Project offered policy implementation workshops to health staff delivering services to young Aboriginal children. In addition to the evidence-based policy, a suite of resources were made available to support service delivery. The EACHS is a framework used by agencies to deliver consistent care and support governance when providing child health services to Aboriginal families across Western Australia. Providing a policy that was consistent with identified service strengths allowed agencies to individually build their capacity to deliver child health checks, using existing resources, at their own pace. © 2015 Commonwealth of Australia.

    The visual analogue scale is a self-reported, validated tool to measure quality of life (QoL). Our purpose was to determine whether baseline QoL predicted strokes in the ALLHAT study (Antihypertensive and Lipid Lowering Treatment to Prevent Heart Attack Trial) and evaluate determinants of poststroke change in QoL. In the ALLHAT study, among the 33 357 patients randomized to treatment arms, 1525 experienced strokes; 1202 (79%) strokes were nonfatal. This study cohort includes 32 318 (97%) subjects who completed the baseline visual analogue scale QoL estimate. QoL was measured on a visual analogue scale and adjusted using a Torrance transformation (transformed QoL [TQoL]). Kaplan-Meier curves and adjusted proportional hazards analyses were used to estimate the effect of TQoL on the risk of stroke, on a continuous scale (0-1) and by quartiles (≤0.81, >0.81≤0.89, >0.89≤0.95, >0.95). We analyzed the change from baseline to first poststroke TQoL using adjusted linear regression. After adjusting for multiple stroke risk factors, the hazard ratio for stroke events for baseline TQoL was 0.93 (95% confidence interval, 0.89-0.98) per 0.1 U increase. The lowest baseline TQoL quartile had a 20% increased stroke risk (hazard ratio=1.20 [95% confidence interval, 1.00-1.44]) compared with the reference highest quartile TQoL. Poststroke TQoL change was significant within all treatment groups ( P ≤0.001). Multivariate regression analysis revealed that baseline TQoL was the strongest predictor of poststroke TQoL with similar results for the untransformed QoL. The lowest baseline TQoL quartile had a 20% higher stroke risk than the highest quartile. Baseline TQoL was the only factor that predicted poststroke change in TQoL.

    The Caribbean has the highest prevalence rates of HIV/AIDS outside sub-Saharan Africa, and a broad literature suggests an ecological association between tourism areas and sexual vulnerability. Tourism employees have been shown to engage in high rates of sexual risk behaviours. Nevertheless, no large-scale or sustained HIV prevention interventions have been conducted within the tourism industry. Policy barriers and resources are under-studied. In order to identify the policy barriers and resources for HIV prevention in the tourism sector, our research used a participatory approach involving a multisectoral coalition of representatives from the tourism industry, government, public health and civil society in the Dominican Republic. We conducted 39 in-depth semi-structured interviews with policy makers throughout the country focusing on: prior experiences with HIV prevention policies and programmes in the tourism sector; barriers and resources for such policies and programmes; and future priorities and recommendations. Findings suggest perceptions among policy makers of barriers related to the mobile nature of tourism employees; the lack of centralized funding; fear of the 'image problem' associated with HIV; and the lack of multisectoral policy dialogue and collaboration. Nevertheless, prior short-term experiences and changing attitudes among some private sector tourism representatives suggest emerging opportunities for policy change. We argue that the time is ripe for dialogue across the public-private divide in order to develop regulatory mechanisms, joint responsibilities and centralized funding sources to ensure a sustainable response to the HIV-tourism linkage. Policy priorities should focus on incorporating HIV prevention as a component of occupational health; reinforcing workers' health care rights as guaranteed by existing law; using private sector tourism representatives who support HIV prevention as positive role models for national campaigns; and

    Nonvalvular atrial fibrillation is the most common arrhythmia. Patients with nonvalvular atrial fibrillation are at increased risk of stroke; therefore, we evaluated the efficacy and safety of different approaches to prevent this major complication. We conducted electronic database searches of phase III randomized controlled trials. The groups were novel oral anticoagulants, Watchman left atrial appendage occlusion device (DEVICE), and warfarin. Efficacy outcomes were stroke or systemic embolism, and all-cause mortality. Safety outcome was major bleeding and procedure-related complications. A subgroup analysis of the elderly population was done. We used random-effects model to compare pooled outcomes and tested for heterogeneity. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed for each outcome. Seven randomized controlled trials (n=73,978) were included. There was a significant difference favoring novel oral anticoagulants for systemic embolism (OR, 0.84; 95% CI, 0.72-0.97; P=0.01), all-cause mortality (OR, 0.89; 95% CI, 0.84-0.94; P<0.001), and safety outcomes (OR, 0.79; 95% CI, 0.65-0.97; P=0.026) compared with warfarin. No difference was seen between DEVICE and warfarin for efficacy end points; however, DEVICE had more complications (OR, 1.85; 95% CI, 1.14-3.01; P=0.012). In the elderly (6 randomized controlled trials, n=30,699), systemic embolism was favored with novel oral anticoagulants over warfarin (OR, 0.77; 95% CI, 0.68-0.87; P≤0.001). No evidence of significant publication bias was found. Novel oral anticoagulants is superior to warfarin for stroke prevention in nonvalvular atrial fibrillation. This benefit was also observed in the elderly population. DEVICE is a reasonable noninferior alternative to warfarin for stroke prevention, but cautious use is essential given safety concerns. © 2015 American Heart Association, Inc.

    Full Text Available Abstract Background Stroke is a serious complication of sickle cell disease (SCD in children. Transcranic Doppler (TCD is a well-established predictor of future cerebrovascular symptoms: a blood flow velocity >200 cm/sec in the Middle Cerebral Artery (MCA correlates with a high risk of stroke in cohorts of African-american HbS/HbS patients. In North-East Italy the recent increase in SCD patients is mainly due to immigration from Africa. A comprehensive care program for children with SCD was established in our Center since 2004, but a wide and routine screening for Primary stroke prevention needs to be developed. Methods In order to verify the feasibility of TCD and Transcranial color coded Sonography (TCCS screening in our setting and the applicability of international reference values of blood velocities to our population of African immigrants with HbS/HbS SCD, we performed TCD and TCCD in 12 HbS/HbS African children and two groups of age-matched controls of Caucasian and African origin respectively. TCD and TCCS were performed on the same day of the scheduled routine hematologic visit after parental education. Results All parents accepted to perform the sonography to their children. TCD and TCCD were performed in all patients and an adequate temporal window could be obtained in all of them. Pulsatility index and depth values in both the MCA and the Basilar Artery (BA were similar at TCD and TCCS evaluation in the three groups while time-average maximum velocities (TAMM, peak systolic velocity and diastolic velocity in the MCA and BA were higher in the patients' group on both TCD and TCCS evaluation. African and Caucasian healthy controls had similar lower values. Conclusion Our preliminary data set the base to further evaluate the implementation of a primary stroke prevention program in our setting of HbS/HbS African immigrants and HbS/beta thalassemia Italians. Parental education-preferably in the native language- on stroke risk and

    The purpose of this research is to use the Public Health Workforce Interests and Needs Survey to assess in greater detail state injury prevention staff perceptions of policy development and related skills and their awareness and perception of "Health in All Policies" (HiAP). The Public Health Workforce Interests and Needs Survey gauged public health practitioners' perspectives on workplace environment, job satisfaction, national trends, and training needs, and gathered demographics on the workforce. This study utilizes data from the state health agency frame only, focusing solely on those permanently employed, central office staff in injury prevention. Respondents were sampled from 5 paired Health and Human Services regions. Approximately 25 000 invitations were sent to central office employees. The response rate was 46% (n = 10 246). The analysis in this article includes only injury prevention employees with programmatic roles, excluding clerical and custodial staff, providing us with a total of 97 respondents. When weighted, this resulted in a weighted population size of 365 injury prevention workers. The main outcome measures include demographics, responses to understanding of and skill levels related to policy development, and perceptions of HiAP public health trend. State injury prevention workers reported lower policy-making skill but had an overall appreciation of the importance of policies. In general, state injury prevention workers heard of HiAP, thought there should be more emphasis on it, but did not think that HiAP would have an impact on their day-to-day work. Efforts are needed for all state injury prevention workers to become better skilled in policy development, implementation, and evaluation in order to become stronger injury prevention advocates and role models.

    The Canadian Partnership Against Cancer funded 12 large-scale knowledge to action cancer and chronic disease prevention projects between 2009 and 2016 through the Coalitions Linking Action and Science for Prevention (CLASP) initiative. Two projects, Healthy Canada by Design (HCBD) and Children's Mobility, Health and Happiness (CMHH), developed policies to address physical activity and the built environment through a multisectoral approach. A qualitative analysis involving a review of 183 knowledge products and 8 key informant interviews was conducted to understand what policy changes occurred, and the underlying critical success factors, through these projects. Both projects worked at the local level to change physical activity and built environment policy in 203 sites, including municipalities and schools. Both projects brought multisectoral expertise (e.g., public health, land use planning, transportation engineering, education, etc.) together to inform the development of local healthy public policy in the areas of land use, transportation and school travel planning. Through the qualitative analysis of the knowledge products and key informant interviews, 163 policies were attributed to HCBD and CMHH work. Fourteen "pathways to policy" were identified as critical success factors facilitating and accelerating the development and implementation of physical activity and built environment policy. Of the 14 pathways to policy, 8 had a focus on multisectoral collaboration. The lessons learned from the CLASP experience could support enhanced multisectoral collaborations to accelerate the development and implementation of physical activity and built environment policy in new jurisdictions across Canada and internationally.

    Japan's national suicide prevention efforts following the 1998 surge in the number of suicide deaths can be divided into three stages: the first stage administrated mainly by the health ministry (1998-2005), the second and transitional stage when it was upgraded to a full governmental issue (2005-2006), and the third and present stage following the promulgation of the Basic Act for Suicide Prevention in 2006. In June 2007, the General Principles for Suicide Prevention Policy (GPSP), a guideline on how the national government should act to promote suicide prevention, was announced, urging local governments to tackle the problem of suicide. The GPSP was set to be revised after around five years from its publication, and, thus, a revised GPSP was published in August of 2012. Based on the five years of challenges, the revised GPSP states that suicide prevention strategies should move on to more practical and community-oriented ones. The National Center of Neurology and Psychiatry (NCNP), through its Center for Suicide Prevention, played a coordinating role in putting forward a proposal for the revision, working with 29 academic societies including the Japanese Society of Psychiatry and Neurology (JSPN). In February 2013, by further developing the relationships with academic societies, etc., which were forged in the above-mentioned process, NCNP set up the Preparatory Committee for the Evidence-based Suicide Prevention Consortium in order to contribute to suicide prevention strategies from an academic perspective. Meanwhile, in the World Health Organization's 66th World Health Assembly held in May 2013, the Comprehensive Mental Health Action Plan 2013-2020 was approved. Its core principle is "no health without mental health", and it has the following four objectives: (1) to strengthen effective leadership and governance for mental health; (2) to provide comprehensive, integrated, and responsive mental health and social care services in community-based settings; (3) to

    Elevated concentrations of homocysteine are associated with cerebral small vessel disease (CSVD). B-vitamin supplementation with folate and vitamins B12 and B6 reduces homocysteine concentrations. In a substudy of the VITAmins TO Prevent Stroke (VITATOPS) trial, we assessed the hypothesis that the addition of once-daily supplements of B vitamins would reduce the progression of CSVD-related brain lesions. A total of 359 patients with recent stroke or transient ischemic attack, who were randomly allocated to double-blind treatment with placebo or b vitamins, underwent brain MRI at randomization and after 2 years of B-vitamin supplementation. MR images were analyzed blinded to treatment allocation. Outcomes related to the prespecified hypothesis were progression of white matter hyperintensities and incident lacunes. We also explored the effect of B-vitamin supplementation on the incidence of other ischemic abnormalities. After 2 years of treatment with b vitamins or placebo, there was no significant difference in white matter hyperintensities volume change (0.08 vs 0.13 cm3; P=0.419) and incidence of lacunes (8.0% vs 5.9%, P=0.434; odds ratio=1.38). In a subanalysis of patients with MRI evidence of severe CSVD at baseline, b-vitamin supplementation was associated with a significant reduction in white matter hyperintensities volume change (0.3 vs 1.7 cm3; P=0.039). Daily B-vitamin supplementation for 2 years did not significantly reduce the progression of brain lesions resulting from presumed CSVD in all patients with recent stroke or transient ischemic attack but may do so in the subgroup of patients with recent stroke or transient ischemic attack and severe CSVD. http://vitatops.highway1.com.au/.

    Spina bifida is a serious and largely preventable neural tube birth defect and an important cause of mortality and lifelong disability. The People and Organizations United for Spina Bifida and Hydrocephalus (PUSH!) Global Alliance was formed in 2014 to provide a common platform for various organizations worldwide to raise the visibility of spina bifida and hydrocephalus. In its formative phase, the alliance recognized that in order to accelerate surveillance, prevention, and care for these conditions, there was a need to provide an evidence-based assessment of how nations are performing in specific areas. In this paper, we describe the impetus for, and the process of, developing country-level scorecards for spina bifida surveillance, prevention and care. The PUSH! Executive Committee formulated a comprehensive list of six actionable indicators measuring availability of published studies on population-based folate studies; surveillance of prevalence and mortality; prevention-based policies; access to care; and quality of life associated with spina bifida. Rubrics were developed to score each country on the aforementioned indicators. Country scores were pooled across each indicator and the composite scores ranged between zero and three if there was a need for improvement, four and five if they were in good standing, or six for an excellent status. The scorecard included country-specific recommendations assimilated from the literature and published guidelines to aid policy makers in accelerating surveillance and prevention, and improving the care and quality of life indicators. For comparison, country-level scorecards were grouped by WHO-regions. Score cards were made available publicly through the website "www.pu-sh.org". Copyright © 2017 Elsevier Inc.

    Objective To assess high school athletic programs’ infection prevention policies and procedures and to estimate the frequency of skin and soft tissue infections (SSTIs) among Iowa’s high school athletes. Methods An on-line survey of high school athletic programs. Results Nearly 60% of programs responded. Schools in higher classifications were more likely to have a certified athletic trainer (AT; P athletes with SSTIs from participating in athletic events than were schools in lower classifications (P = 0.0002). Programs that had an AT reported that athletic training equipment (P = 0.01) and tables (P = 0.02) were cleaned more frequently than did programs without ATs. Programs were significantly more likely to provide training equipment than to provide soap or towels. About 57% of programs reported that at least one athlete acquired an SSTI during the prior school year, including methicillin- resistant Staphylococcus aureus (N = 14; 10.8%). Programs that had an AT (P = 0.02) were in higher classifications (P athletes about SSTIs (P athletes with SSTIs (P = 0.01) were more likely than other programs to report having at least one athlete with an SSTI. The estimated SSTI rate per 1000 athletes ranged from 22.0 in 1A to 5.9 in 4A programs. Conclusions SSTIs are common among Iowa’s high school athletes. Staff should review and update their infection prevention policies. Athletic programs need resources to support infection prevention efforts. PMID:24027469

    2017-01-01

    This paper proposes a preventive maintenance policy for a single-unit system whose failure has two competing and dependent causes, i.e., internal deterioration and sudden shocks. The internal failure process is divided into two stages, i.e. normal and defective. Shocks arrive according to a non-homogeneous Poisson process (NHPP), leading to the failure of the system immediately. The occurrence rate of a shock is affected by the state of the system. Both an age-based replacement and finite number of periodic inspections are schemed simultaneously to deal with the competing failures. The objective of this study is to determine the optimal preventive replacement interval, inspection interval and number of inspections such that the expected cost per unit time is minimized. A case study on oil pipeline maintenance is presented to illustrate the maintenance policy. - Highlights: • A maintenance model based on two-stage deterioration and sudden shocks is developed. • The impact of internal system state on external shock process is studied. • A new preventive maintenance strategy combining age-based replacements and periodic inspections is proposed. • Postponed replacement of a defective system is provided by restricting the number of inspections.

    The promotion of healthy eating and physical activity within school settings is an important component of population-based strategies to prevent obesity; however, adolescents may be vulnerable to weight-related messages, as rapid development during this life stage often leads to preoccupation with body size and shape. This study examines secular trends in secondary school curricula topics relevant to the prevention of unhealthy weight-control behaviors; describes cross-sectional associations between weight-related curricula content and students' use of weight-control behaviors; and assesses whether implementation of school-based obesity-prevention policies/practices is longitudinally related to students' weight-control behaviors. The Minnesota School Health Profiles and Minnesota Student Survey (grades 9 and 12) data were used along with National Center for Education Statistics data to examine secular trends, cross-sectional associations (n=141 schools), and longitudinal associations (n=42 schools). Students self-reported their height and weight along with past-year use of healthy (eg, exercise), unhealthy (eg, fasting), and extreme (eg, use laxatives) weight-control behaviors. Descriptive statistics, generalized estimating equations, and generalized linear regression models accounting for school-level demographics. There was no observable pattern during the years 2008 to 2014 in the mean number of curricula topics addressing unhealthy weight-control behaviors, despite an increase in the prevalence of curricula addressing acceptance of body-size differences. Including three vs fewer weight-control topics and specifically including the topic of eating disorders in the curricula was related to a lower school-level percent of students using any extreme weight-control behaviors. In contrast, an overall measure of implementing school-based obesity-prevention policies/practices (eg, prohibited advertising) was unrelated to use of unhealthy or extreme behaviors

    Recent reports have linked the use of phosphodiesterase type 5 (PDE-5) inhibitors with increased rates of high-risk sexual behavior and HIV transmission in some individuals. A National Institute of Mental Health (NIMH)-funded, multidisciplinary conference was convened to evaluate scientific research, clinical and ethical considerations, and public policy implications of this topic. Published and unpublished findings on effects of PDE-5 inhibitors on sexual behavior; published guidelines and management recommendations. Leading investigators in relevant disciplines (e.g., public health, epidemiology, medical ethics, urology, psychology) participated in a 2-day meeting, including representatives of government, scientific, and regulatory agencies (the Centers for Disease Control, Food and Drug Administration, NIMH, and the National Institute on Drug Abuse). Panelists provided critical reviews of substantive areas of research, followed by question and answer sessions on each topic. On the second day, working groups were convened to identify critical gaps and priorities in three major areas: (i) research and evaluation needs; (ii) prevention strategies and clinical management issues; and (iii) policy and prevention implications. Research needs and priorities were categorized into four specific areas: (i) basic and clinical/laboratory research; (ii) epidemiology and risk factors; (iii) social-behavioral processes and interventions; and (iv) prevention/policy and educational needs. Identified gaps in the available data include populations at risk (e.g., risk among heterosexuals, risk profiles among subpopulations of men who have sex with men) and the specific role of PDE-5 inhibitors in HIV seroconversion. Specific areas of emphasis were the need for safer sex counseling, comprehensive sexually transmitted infection (STI) screening and follow-up when indicated, avoidance of potentially dangerous drug interactions, and potential benefits of testosterone replacement for HIV

We assembled a representative secondary prevention cohort from four tertiary care stroke centers to identify factors that independently influence therapeutic decision making 1) not to anticoagulate with either VKA or DOAC and 2) to use DOAC if the patient appears suitable for oral anticoagulant therapy. We identified all patients discharged with the diagnoses 'ischemic stroke' (ICD-10 code I63) or 'transient ischemic attack' (G45) in combination with 'atrial fibrillation' (I48) during 1 year. We performed binary logistic regression analyses to identify factors independently influencing the aforementioned decisions. Our cohort comprised 758 patients. At discharge from the stroke service, 374 patients (49·3%) received oral anticoagulant therapy. Older age, severe stroke, poor recovery in the acute phase, and higher serum creatinine were independent factors to withhold oral anticoagulant therapy, whereas prior oral anticoagulant therapy favored the decision to anticoagulate. Among patients who were anticoagulated, prescription was balanced for VKA (50·3%) and DOAC (49·7%). Renal function and prior oral anticoagulant therapies were the most important factors in this decision. Shortly after their marketing, DOAC are used as frequently as VKA for secondary stroke prevention in patients with atrial fibrillation. The decision between VKA and DOAC is mainly determined by the patient's renal function and the absence or presence of prior oral anticoagulant therapy. © 2014 World Stroke Organization.

    Research on the types of interventions needed for population-level prevention of childhood obesity in complex societal systems can benefit from greater use of systems-science concepts and tools. We report outcomes of a funding programme promoting incorporation of systems-science approaches into studies of imminent policy or environmental changes potentially impacting childhood obesity. Seven funding cycles over 3 years yielded 172 initial submissions from 29 US states and 25 other countries were analyzed. Submissions focused primarily on aspects of school or child-care settings, parks and recreational settings, or access to healthy food; about half reflected attention to systems perspectives. Analysis of initial submissions as well as the 15 funded projects showed some success in motivating use of systems concepts and tools but suggested the need for a more focused effort to educate and prepare the childhood obesity prevention research community for this potentially crucial type of research. © 2016 World Obesity Federation.

    The world faces an unprecedented growth in cancer incidence over the next fifty years, the majority of the burden falling on low-middle income countries. At the same time as the changing demographic profiles, including global population ageing we are also seeing the rapid globalisation of pro-cancer behaviours and commodities such as tobacco. The human and economic impact will continue to be severe unless radical changes occur to current public policy mismatches in cancer prevention. At the same time high level political actions through bodies such as the UN suggest that supra-national approaches are needed to solve these issues. However, we argue that only local nation-state approaches can fundamentally address cancer risk and enhance prevention in a globalised world. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Epidemiological studies suggest that raised plasma concentrations of total homocysteine might be a risk factor for major vascular events. Whether lowering total homocysteine with B vitamins prevents major vascular events in patients with previous stroke or transient ischaemic attack is unknown. We aimed to assess whether the addition of once-daily supplements of B vitamins to usual medical care would lower total homocysteine and reduce the combined incidence of non-fatal stroke, non-fatal myocardial infarction, and death attributable to vascular causes in patients with recent stroke or transient ischaemic attack of the brain or eye. In this randomised, double-blind, parallel, placebo-controlled trial, we assigned patients with recent stroke or transient ischaemic attack (within the past 7 months) from 123 medical centres in 20 countries to receive one tablet daily of placebo or B vitamins (2 mg folic acid, 25 mg vitamin B6, and 0.5 mg vitamin B12). Patients were randomly allocated by means of a central 24-h telephone service or an interactive website, and allocation was by use of random permuted blocks stratified by hospital. Participants, clinicians, carers, and investigators who assessed outcomes were masked to the assigned intervention. The primary endpoint was the composite of stroke, myocardial infarction, or vascular death. All patients randomly allocated to a group were included in the analysis of the primary endpoint. This trial is registered with ClinicalTrials.gov, NCT00097669, and Current Controlled Trials, ISRCTN74743444. Between Nov 19, 1998, and Dec 31, 2008, 8164 patients were randomly assigned to receive B vitamins (n=4089) or placebo (n=4075). Patients were followed up for a median duration of 3.4 years (IQR 2.0-5.5). 616 (15%) patients assigned to B vitamins and 678 (17%) assigned to placebo reached the primary endpoint (risk ratio [RR] 0.91, 95% CI 0.82 to 1.00, p=0.05; absolute risk reduction 1.56%, -0.01 to 3.16).

    Full Text Available Abstract Background Compelling evidence shows that appropriate use of anticoagulation in patients with nonvalvular atrial fibrillation reduces the risk of ischaemic stroke by 67% and all-cause mortality by 26%. Despite this evidence, anticoagulation is substantially underused, resulting in avoidable fatal and disabling strokes. Methods DESPATCH is a cluster randomised controlled trial with concealed allocation and blinded outcome assessment designed to evaluate a multifaceted and tailored implementation strategy for improving the uptake of anticoagulation in primary care. We have recruited general practices in South Western Sydney, Australia, and randomly allocated practices to receive the DESPATCH intervention or evidence-based guidelines (control. The intervention comprises specialist decisional support via written feedback about patient-specific cases, three academic detailing sessions (delivered via telephone, practice resources, and evidence-based information. Data for outcome assessment will be obtained from a blinded, independent medical record audit. Our primary endpoint is the proportion of nonvalvular atrial fibrillation patients, over 65 years of age, receiving oral anticoagulation at any time during the 12-month posttest period. Discussion Successful translation of evidence into clinical practice can reduce avoidable stroke, death, and disability due to nonvalvular atrial fibrillation. If successful, DESPATCH will inform public policy, providing quality evidence for an effective implementation strategy to improve management of nonvalvular atrial fibrillation, to close an important evidence-practice gap.

    Genetic enzyme variation and vitamin intake are important determinants of blood homocyst(e)ine levels. The prevalence of common genetic polymorphisms influencing homocyst(e)ine levels varies by race, and vitamin intake varies by socioeconomic status. Therefore, we examined the effect of vitamin intake, race, and socioeconomic status on the association of homocyst(e)ine with stroke risk. All 59 hospitals in the greater Baltimore-Washington area participated in a population-based case-control study of stroke in young women. One hundred sixty-seven cases of first ischemic stroke among women aged 15 to 44 years were compared with 328 controls identified by random-digit dialing from the same region. Risk factor data were collected by standardized interview and nonfasting phlebotomy. Plasma homocyst(e)ine was measured by high-performance liquid chromatography and electrochemical detection. Blacks and whites did not differ in median homocyst(e)ine levels, nor did race modify the association between homocyst(e)ine and stroke. After adjustment for cigarettes per day, poverty status, and regular vitamin use, a plasma homocyst(e)ine level of >/=7.3 micromol/L was associated with an odds ratio for stroke of 1.6 (95% CI, 1.1 to 2.5). The association between elevated homocyst(e)ine and stroke was independent not only of traditional vascular risk factors but also of vitamin use and poverty status. The degree of homocyst(e)ine elevation associated with an increased stroke risk in young women is lower than that previously reported for middle-aged men and the elderly and was highly prevalent, being present in one third of the control group.

    Although HIV in the Middle East and North Africa is currently characterized as a low seroprevalence epidemic, there are numerous factors that are present in the region that could prevent—or exacerbate—the epidemic. The time to invest substantially in prevention—and gender-specific prevention in particular—is now. Given that most policy makers do not make gender-specific plans as epidemics progress, our research team—which draws upon expertise from both within and outside the region—worked together to make programmatic and policy suggestions in the Middle East and North Africa region in 5 key areas: (1) gender-specific and gender transformative HIV prevention interventions; (2) access to quality education and improvements in life skills and sex education; (3) economic empowerment; (4) property rights; and (5) antiviolence. In short, this work builds upon many ongoing efforts in the region and elucidates some of the links between gendered empowerment and health outcomes around the world, particularly HIV and AIDS.

    Despite significant advances in our understanding of the biological bases of addictions, these disorders continue to represent a huge public health burden that is associated with substantial personal suffering. Efforts to target addictions require consideration of how the improved biological understanding of addictions may lead to improved prevention, treatment, and policy initiatives. In this article, we provide a narrative review of current biological models for addictions with a goal of placing existing data and theories within a translational and developmental framework targeting the advancement of prevention, treatment, and policy strategies. Data regarding individual differences, intermediary phenotypes, and main and interactive influences of genetic and environmental contributions in the setting of developmental trajectories that may be influenced by addictive drugs or behavior indicate complex underpinnings of addictions. Consideration and further elucidation of the biological etiologies of addictions hold significant potential for making important gains and reducing the public health impact of addictions.

    2017-10-01

    Full Text Available Exertional heat stroke (EHS is an emergency with a high mortality rate, characterized by acute onset and identification difficulties. EHS prevention focuses on evaluating the environment by professionals, making preventive measures in advance, identifying internal and external risk factors for the onset of disease, carrying out prior heat adaptation and endurance training, monitoring the status of high risk persons in real time. After occurrence of EHS, the key to success treatment is on-site accurate identification and diagnosis and rapid implementation of effective cooling measures, thus winning time of EHS patients transferred to the hospital for the treatment. This article reviews the current status of EHS prevention and treatment in domestic and foreign from the scene to the hospital. Summarizing the recognition, diagnosis, cooling measures, treatment concepts and principles of EHS, we hope to provide a reference for the rescue of EHS in hospital and outside.

    Full Text Available Background. Limited physical activity (PA is a risk factor for childhood obesity. In Netherlands, as in many other countries worldwide, local policy officials bear responsibility for integrated PA policies, involving both health and nonhealth domains. In practice, its development seems hampered. We explore which obstacles local policy officials perceive in their effort. Methods. Fifteen semistructured interviews were held with policy officials from health and nonhealth policy domains, working at strategic, tactic, and operational level, in three relatively large municipalities. Questions focused on exploring perceived barriers for integrated PA policies. The interviews were deductively coded by applying the Behavior Change Ball framework. Findings. Childhood obesity prevention appeared on the governmental agenda and all officials understood the multicausal nature. However, operational officials had not yet developed a tradition to develop integrated PA policies due to insufficient boundary-spanning skills and structural and cultural differences between the domains. Tactical level officials did not sufficiently support intersectoral collaboration and strategic level officials mainly focused on public-private partnerships. Conclusion. Developing integrated PA policies is a bottom-up innovation process that needs to be supported by governmental leaders through better guiding organizational processes leading to such policies. Operational level officials can assist in this by making progress in intersectoral collaboration visible.

    To assess the awareness, facilitators, and barriers to policy implementation related to obesity prevention for primary school children. A cross-sectional study administered using an online questionnaire. Conducted in 447 primary schools in a state in Malaysia. One school administrator from each school served as a participant. The questionnaires consisted of 32 items on awareness, policy implementation, and facilitators and barriers to policy implementation. Descriptive analysis was used to describe the awareness, facilitators, and barriers of policies implementation. Association between schools' characteristics and policy implementation was assessed using logistic regression. The majority (90%) of school administrators were aware of the policies. However, only 50% to 70% of schools had implemented the policies fully. Reported barriers were lack of equipment, insufficient training, and limited time to complete implementation. Facilitators of policy implementation were commitment from the schools, staff members, students, and canteen operators. Policy implementation was comparable in all school types and locality; except the policy on "Food and Drinks sold at the school canteens" was implemented by more rural schools compared to urban schools (odds ratio: 1.74, 95% confidence interval: 1.13-2.69). Majority of the school administrators were aware of the existing policies; however, the implementation was only satisfactory. The identified barriers to policy implementation were modifiable and thus, the stakeholders should consider restrategizing plans in overcoming them.

    A proper strategy for fighting hospital malnutrition should include nutritional screening of all hospitalized patients, adequate utilization of the Hospital facilities - such as Clinical Nutrition Services or Nutrition Teams - and an adequate algorithm for the adoption of proper nutrition support (oral, enteral or parenteral) with proper timing. The main aim of the present study was to investigate the current policies of different non-intensive wards of our institution (a 1100 beds University Hospital) in terms of prevention of hospital malnutrition. We conducted a one-day survey to verify the current policies of nutritional screening and the indication to nutritional support in adult patients, interviewing nurses and physicians of our non-intensive hospital wards. A total of 29 wards were considered, which sum up to 755 hospitalized patients. We found that nutritional screening at admission is routinely assessed only in 41% of wards and that oral nutrient intake is controlled regularly only in 72%. Indication to clinical nutrition support and specifically to artificial nutrition is not consistent with the current international guidelines. Only 14% of patients were receiving artificial nutrition at the moment of the survey and the majority of them were given parenteral nutrition rather than enteral feeding. Our survey confirmed that in large hospitals the main barriers to the fight against hospital malnutrition are the lack of knowledge and/or commitment by nurses and physicians as well as the lack of well-defined hospital policies on early nutritional screening, surveillance of nutritional status and indication to nutrition support.

    Full Text Available OBJECTIVE: This study aims to perform a budget impact analysis of the use of three available novel oral anticoagulant agents (NOACs for preventing thromboembolic events in Italian patients with non‑valvular atrial fibrillation (NVAF.METHODS: Estimated Italian population of patients was run through a previously published lifetime decision tree/Markov model simulating their treatment with the available therapeutic options: dabigatran at two dose levels (110 mg/bid for the over 80 years old, 150 mg/bid for younger NVAF patients, rivaroxaban (20 mg/uid, and apixaban (5 mg/bid. Effectiveness and safety estimates derive from an adjusted indirect treatment comparison using warfarin as link. The main clinical events considered in the model are ischemic and hemorrhagic stroke, systemic thromboembolism, bleeds (both major and clinically relevant minor and cardiovascular hospitalizations, besides treatment discontinuations. Epidemiological data and unit costs, actualized to 2013, are collected from Italian published sources. The budget impact analysis evaluates the financial impact of apixaban introduction by comparing expected 1,2, and 3 years costs in hypothetical scenarios: with and without apixaban. Italian NVAF patient population estimation is based on official apixaban reimbursement criteria, applying the characteristics of the trial population to national epidemiologic data. Numbers of patients for each regimen are estimated by projecting share evolution. Sensitivity analysis is performed on an alternative non‑experimental population of NVAF patients.RESULTS: Among available NOACs, apixaban was expected to be the least expensive in an estimated patient population of 364,000 Italian patients, allowing for savings of € 1,180,549, € 3,841,429 and € 5,368,918 at 1,2, and 3 years, respectively. Results of the simulation run on an alternative non‑experimental population of NVAF patients yields comparable estimates.CONCLUSIONS: The different

    Full Text Available OBJECTIVES: The aim of this study was to evaluate the cost‑effectiveness of apixaban in the prevention of thromboembolic events in patients with non‑valvular atrial fibrillation (NVAF relatively to standard of care (warfarin or aspirin from the Italian National Health System (SSN perspective.METHODS: A previously published lifetime Markov model was adapted for Italian context. Clinical effectiveness data were acquired from head‑to‑head randomized trials (ARISTOTLE and AVERROES; main events considered in the model were ischemic and hemorrhagic stroke, systemic thromboembolism, bleeds (both major and clinically relevant minor and cardiovascular hospitalizations, besides treatment discontinuations. Expected survival was projected beyond trial duration using national mortality data adjusted for individual clinical risks and adjusted by utility weights for health states acquired from literature. Unit costs were collected from published Italian sources and actualized to 2013. Costs and health gains accruing after the first year were discounted at an annual 3.5% rate. The primary outcome measure of the economic evaluation was the incremental cost effectiveness ratio (ICER, where effectiveness is measured in terms of life‑years and quality adjusted life‑years gained. Deterministic and probabilistic sensitivity analyses (PSA were carried out to assess the effect of input uncertainty.RESULTS: Apixaban is expected to reduce the incidence of ischemic events relative to aspirin and to improve bleeding safety profile when compared to warfarin. Incremental LYs (0.31/0.19, QALYs (0.28/0.20, and costs (1,932/1,104 are predicted with the use of apixaban relative to aspirin and warfarin, respectively.

    Theories of the policy process are recommended as tools to help explain both policy stasis and change. A systematic review of the application of such theoretical frameworks within the field of obesity prevention policy was conducted. A meta-synthesis was also undertaken to identify the key influences on policy decision-making. The review identified 17 studies of obesity prevention policy underpinned by political science theories. The majority of included studies were conducted in the United States (US), with significant heterogeneity in terms of policy level (e.g., national, state) studied, areas of focus, and methodologies used. Many of the included studies were methodologically limited, in regard to rigour and trustworthiness. Prominent themes identified included the role of groups and networks, political institutions, and political system characteristics, issue framing, the use of evidence, personal values and beliefs, prevailing political ideology, and timing. The limited application of political science theories indicates a need for future theoretically based research into the complexity of policy-making and multiple influences on obesity prevention policy processes.

    Cho, Yoshinori; Inagaki, Masatoshi

    2014-01-01

    In view of the fact that the suicide rate in Japan has remained high since 1998, the Basic Act on Suicide Prevention was implemented in 2006 with the objective of comprehensively promoting suicide prevention measures on a national scale. Based on this Basic Act, in 2007, the Japanese government formulated the General Principles of Suicide Prevention Policy as a guideline for recommended suicide prevention measures. These General Principles were revised in 2012 in accordance with the initial plan of holding a review after five years. The Basic Act places an emphasis on the various social factors that underlie suicides and takes the perspective that suicide prevention measures are also social measures. The slogan of the revised General Principles is "Toward Realization of a Society in which Nobody is Driven to Commit Suicide". The General Principles list various measures that are able to be used universally. These contents would be sufficient if the objective of the General Principles were "realization of a society that is easy to live in"; however, the absence of information on the effectiveness and order of priority for each measure may limit the specific effectiveness of the measures in relation to the actual prevention of suicide. In addition, considering that nearly 90% of suicide victims are in a state at the time of committing suicide in which a psychiatric disorder would be diagnosed, it would appear from a psychiatric standpoint that measures related to mental health, including expansion of psychiatric services, should be the top priority in suicide prevention measures. However, this is not the case in the General Principles, in either its original or revised form. Revisions to the General Principles related to clinical psychiatry provide more detailed descriptions of measures for individuals who unsuccessfully attempt suicide and identify newly targeted mental disorders other than depression; however, the overall proportion of contents relating to

    Context Patients with symptomatic atherosclerotic internal carotid artery occlusion (AICAO) and hemodynamic cerebral ischemia are at high risk for subsequent stroke when treated medically. Objective Test the hypothesis that extracranial-intracranial (EC-IC) bypass surgery, added to best medical therapy, reduces subsequent ipsilateral ischemic stroke in patients with recently symptomatic AICAO and hemodynamic cerebral ischemia. Design Parallel group, randomized, open-label, blinded-adjudication clinical treatment trial conducted from 2002–2010. Setting 49 clinical centers and 18 positron emission tomography (PET) centers in the United States and Canada. The majority were academic medical centers. Participants Arteriographically-confirmed AICAO causing hemispheric symptoms within 120 days and hemodynamic cerebral ischemia identified by ipsilateral increased oxygen extraction fraction measured by PET. 195 were randomized: 97 to surgery and 98 to no surgery. Follow-up for the primary endpoint until occurrence, 2 years, or end of trial was 99% complete. No participant withdrew because of adverse events. Interventions Anastomosis of superficial temporal artery branch to a middle cerebral artery cortical branch for the surgical group. Anti-thrombotic therapy and risk factor intervention were recommended for all. Main Outcome Measure For all participants who were assigned to surgery and received surgery, the combination of (1) all stroke and death from surgery through 30 days post surgery and (2) ipsilateral ischemic stroke within 2 years of randomization. For the nonsurgical group and participants assigned to surgery who did not receive surgery was the combination of (1) all stroke and death from randomization to randomization plus 30 days and (2) ipsilateral ischemic stroke within two years of randomization. Results The trial was terminated early for futility. Two-year rates for the primary endpoint were 21.0% (95% CI, 12.8% to 29.2%; 20 events) for the surgical group

    Atrial fibrillation (AF) causes a third of all strokes, but often goes undetected before stroke. Identification of unknown AF in the community and subsequent anti-thrombotic treatment could reduce stroke burden. We investigated community screening for unknown AF using an iPhone electrocardiogram (iECG) in pharmacies, and determined the cost-effectiveness of this strategy.Pharmacists performedpulse palpation and iECG recordings, with cardiologist iECG over-reading. General practitioner review/12-lead ECG was facilitated for suspected new AF. An automated AF algorithm was retrospectively applied to collected iECGs. Cost-effectiveness analysis incorporated costs of iECG screening, and treatment/outcome data from a United Kingdom cohort of 5,555 patients with incidentally detected asymptomatic AF. A total of 1,000 pharmacy customers aged ≥65 years (mean 76 ± 7 years; 44% male) were screened. Newly identified AF was found in 1.5% (95% CI, 0.8-2.5%); mean age 79 ± 6 years; all had CHA2DS2-VASc score ≥2. AF prevalence was 6.7% (67/1,000). The automated iECG algorithm showed 98.5% (CI, 92-100%) sensitivity for AF detection and 91.4% (CI, 89-93%) specificity. The incremental cost-effectiveness ratio of extending iECG screening into the community, based on 55% warfarin prescription adherence, would be $AUD5,988 (€3,142; $USD4,066) per Quality Adjusted Life Year gained and $AUD30,481 (€15,993; $USD20,695) for preventing one stroke. Sensitivity analysis indicated cost-effectiveness improved with increased treatment adherence.Screening with iECG in pharmacies with an automated algorithm is both feasible and cost-effective. The high and largely preventable stroke/thromboembolism risk of those with newly identified AF highlights the likely benefits of community AF screening. Guideline recommendation of community iECG AF screening should be considered.

    This article is a theoretical-reflexive study that aims to discuss the development and changes in the quality of healthcare assistance to the patient over the years in Brazil, in light of the policies of control and prevention of Healthcare-associated Infection (HAI). Aspects of HAI and the process of change in health policy in Brazil, as well as the quality of assistance associated with its control, are approached in relation to policies of patient safety. There are various new theoretical and practical proposals created in Brazil. In spite of the difficulty of measuring patient safety, directed to the prevention and control of HAI, we emphasize that to only create policies and establish norms, guidelines, and indicators is not sufficient. If no structural support or conditions exist for interventions in the practices of healthcare professionals, aiming at results in acceptable levels, the control of HAI will not be achieved. Resumo Trata-se um estudo teórico-reflexivo, que objetiva discutir a evolução e as mudanças na qualidade da assistência ao paciente, ao longo dos anos no Brasil, à luz das políticas de controle e prevenção da Infecção Relacionada à Assistência à Saúde (IRAS). Aspectos sobre IRAS e o processo de mudança nas políticas de saúde no Brasil, bem como a qualidade da assistência associada ao seu controle, são abordados em relação às políticas de segurança do paciente. Há novas e várias propostas teóricas e práticas criadas no Brasil. Apesar da dificuldade de medir a segurança do paciente, direcionada à prevenção e controle das IRAS, enfatiza-se que somente criar políticas, estabelecer normas, diretrizes e indicadores não são suficientes. Se não houver suporte de estrutura e condições para as intervenções nas práticas dos profissionais na assistência prestada ao paciente, visando resultados em níveis aceitáveis, o controle das IRAS não será alcançado.

    In the United States, unintended pregnancy is a serious health, social, and economic concern. However, the existing prevention policies have proven ineffective at decreasing the rate of unintended pregnancy at a national level. This lack of effective national prevention policy is better understood when viewed through the lens of a policy theory that incorporates an understanding of social construction and its effects on policy development. Through the application of one such policy theory, this article explores how the social construction of fertile women in the United States affects previous and recently enacted unintended pregnancy prevention policies.

    Statins are effective in the primary prevention of atherosclerotic cardiovascular disease. The 2013 American College of Cardiology/American Heart Association (ACC/AHA) guideline expands recommended statin use, but its cost-effectiveness has not been compared with other guidelines. We used the Cardiovascular Disease Policy Model to estimate the cost-effectiveness of the ACC/AHA guideline relative to current use, Adult Treatment Panel III guidelines, and universal statin use in all men 45 to 74 years of age and women 55 to 74 years of age over a 10-year horizon from 2016 to 2025. Sensitivity analyses varied costs, risks, and benefits. Main outcomes were incremental cost-effectiveness ratios and numbers needed to treat for 10 years per quality-adjusted life-year gained. Each approach produces substantial benefits and net cost savings relative to the status quo. Full adherence to the Adult Treatment Panel III guideline would result in 8.8 million more statin users than the status quo, at a number needed to treat for 10 years per quality-adjusted life-year gained of 35. The ACC/AHA guideline would potentially result in up to 12.3 million more statin users than the Adult Treatment Panel III guideline, with a marginal number needed to treat for 10 years per quality-adjusted life-year gained of 68. Moderate-intensity statin use in all men 45 to 74 years of age and women 55 to 74 years of age would result in 28.9 million more statin users than the ACC/AHA guideline, with a marginal number needed to treat for 10 years per quality-adjusted life-year gained of 108. In all cases, benefits would be greater in men than women. Results vary moderately with different risk thresholds for instituting statins and statin toxicity estimates but depend greatly on the disutility caused by daily medication use (pill burden). At a population level, the ACC/AHA guideline for expanded statin use for primary prevention is projected to treat more people, to save more lives, and to cost less

    Full Text Available For patients with atrial fibrillation, non-vitamin K oral anticoagulants, or NOACs (dabigatran, rivaroxaban, edoxaban, and apixaban have been proven non-inferior or superior to warfarin in preventing stroke and systemic embolism, and in risk of haemorrhage. In the pivotal NOAC studies, quality of warfarin treatment was poor with mean time in therapeutic range (TTR 55-65%, compared with ≥70% in Swedish clinical practice.We compared NOACs (as a group to warfarin in non-valvular atrial fibrillation, studying all 12,694 patients starting NOAC treatment within the Swedish clinical register and dosing system Auricula, from July 1, 2011 to December 31, 2014, and matching them to 36,317 patients starting warfarin using propensity scoring. Endpoints were thromboembolic events and major bleedings that were fatal or required hospital care. Outcome data were collected from validated Swedish hospital administrative and clinical registers.Mean age was 72.2 vs 72.3 years, proportion of males 58.2% vs 57.0%, and mean follow-up time 299 vs 283 days for NOACs and warfarin. Distribution of NOACs was: dabigatran 40.3%, rivaroxaban 31.2%, and apixaban 28.5%. Mean TTR was 70%. There were no significant differences in rates of thromboembolic/thrombotic events or gastrointestinal bleeding. NOAC treated patients had lower rates of major bleeding overall, hazard ratio 0.78 (95% confidence interval 0.67-0.92, intracranial bleeding 0.59 (0.40-0.87, haemorrhagic stroke 0.49 (0.28-0.86, and other major bleeding 0.71 (0.57-0.89.For patients with atrial fibrillation, NOACs are as effective for stroke prevention as well-managed warfarin but cause fewer major bleedings.

    To assess the cost-effectiveness of apixaban versus acetylsalicylic acid (ASA) in stroke prevention in patients with non-valvular atrial fibrillation (NVAF) with contraindications of vitamin K antagonists in Spain. A Markov model was adapted, simulating the patient's lifetime. The safety and efficacy of the drugs were obtained from AVERROES clinical trial. The analysis was done from the Spanish National Health System (NHS) and societal perspective. The cost of drugs was calculated according to the recommended doses. The cost of NVAF complications and disease management was obtained from Spanish sources. In a cohort of 1,000 patients with NVAF, during their lifetime numerous complications could be avoided with apixaban versus ASA (48 ischemic strokes, 10 systemic embolism and 53 related deaths). In each patient treated with apixaban more life-years (0.303 LYG) and more quality-adjusted life-years (0.277 QALYs) could be gained. Apixaban would generate more costs per patient for the NHS (€1,742 per patient) but savings would result from the social perspective (€2,887 saved per patient). The cost per LYG and QALY gained would be of €5,749 and €6,289 for the NHS. Apixaban would be dominant (more effective with less costs than ASA) from the societal perspective. The results were stable in both deterministic and probabilistic sensitivity analyses. According to this model, when costs and estimated lifetime outcomes achieved with apixaban are compared with those of ASA, apixaban was assessed to be a cost-effective treatment for the prevention of stroke in patients with NVAF in Spain.

    Full Text Available Considering that Mexican injuries prevention strategies have been focused on injuries caused by car accidents and gender violence, a whole analysis of the injuries registered are performed in this paper to have a wider overview of those agents that can cause injuries around the country. Taking into account the amount of information from both public and private sources, obtained from dynamic cubes reported by the Minister of Health, Big Data strategies are used with the objective of finding an appropriate extraction such as to identify the real correlations between the different variables registered by the Health Sector. The results of the analysis show areas of opportunity to improve the public policies on the subject, particularly in diminishing wounds at living place, public road (pedestrians and work.

    2004-01-01

    For a comprehensive approach to policies on smoking, the map of actors related to tobacco and their political ties needs to be identified. The present article constitutes the first attempt at this task in Spain. Analysis of the press, industry publications, and interviews with key people. Active actors favoring smoking in Spain were identified and classified according to their characteristics, the sphere in which they act, and their preferred territorial arena. We identified tobacco companies (Altadis and Philip Morris dominate the market), tobacco trade organizations (tobacconists), front-line organizations created by the tobacco industry (The Smokers for Tolerance Club), organizations of tobacco growers, and processing companies. Distribution to retailers is dominated by Logista, owned by Altadis. Other sectors to take into account are vending companies and those manufacturing related products (cigarette paper, matches or lighters). The contacts of these actors with the public administration are reviewed, notable among which are the role of the Commissioner for the Tobacco Market, the Ministry of Agriculture, the Ministry of Finance and the Ministry of the Economy. Ties were also found with employers' organizations, some political parties, and unions, as well as with other sectors with social influence such as the media and advertising sectors. The map of actors favoring smoking in Spain is complex and goes beyond the confines of the tobacco industry. Understanding this web is crucial to promoting comprehensive prevention policies.

    2013-10-01

    Child trafficking, including commercial sexual exploitation (CSE), is one of the fastest growing and most lucrative criminal activities in the world. The global enslavement of children affects countless numbers of victims who are trafficked within their home countries or transported away from their homes and treated as commodities to be bought, sold, and resold for labor or sexual exploitation. All over the world, girls are particularly likely to be trafficked into the sex trade: Girls and women constitute 98% of those who are trafficked for CSE. Health and safety standards in exploitative settings are generally extremely low, and the degree of experienced violence has been linked with adverse physical, psychological, and social-emotional development. The human-rights-based approach to child trafficking provides a comprehensive conceptual framework whereby victim-focused and law enforcement responses can be developed, implemented, and evaluated. This article highlights promising policies and programs designed to prevent child trafficking and CSE by combating demand for sex with children, reducing supply, and strengthening communities. The literature reviewed includes academic publications as well as international and governmental and nongovernmental reports. Implications for social policy and future research are presented. © 2013 American Orthopsychiatric Association.

    Obesity is a major risk factor for developing type 2 diabetes, cardiovascular disease, hypertension, dyslipidemias, musculoskeletal diseases, and certain types of cancer. In Mexico the prevalence of overweight and obesity is 16.7% in preschool children, 26.2% in school children, and 30.9% in adolescents. For adults, the prevalence of overweight and obesity is 39.7 and 29.9%, respectively (ENSANUT 2006). Based on an analysis of the situation in Mexico, the need for a comprehensive, multisectoral, multilevel policy and an effective coordination policy have been clearly identified to achieve changes in eating patterns and physical activity to enable the prevention of chronic diseases and to reduce the prevalence of overweight and obesity The combination of strategies and actions of the Mexican National Agreement for Healthy Nutrition proposed by the federal government proposes among its aims for 2012: a reversal in the prevalence of overweight and obesity for children aged 2-5 years in comparison with ENSANUT to stop the increasing prevalence in this condition for school children and adolescents (aged 5-19 years), and to slow down the increasing prevalence of overweight and obesity in adults. This challenge will require important regulatory actions, efficient and adaptable implementation, and participation of all sectors of society.

    Full Text Available The obesity epidemic requires the development of prevention policy targeting individuals most likely to benefit. We used self-reported prepregnancy body weight of all women giving birth in Nova Scotia between 1988 and 2006 to define obesity and evaluated socioeconomic, demographic, and temporal trends in obesity using linear regression. There were 172,373 deliveries in this cohort of 110,743 women. Maternal body weight increased significantly by 0.5 kg per year from 1988, and lower income and rural residence were both associated significantly with increasing obesity. We estimated an additional 82,000 overweight or obese women in Nova Scotia in 2010, compared to the number that would be expected from obesity rates of just two decades ago. The critical age for weight gain was identified as being between 20 and 24 years. This age group is an important transition age between adolescence and adulthood when individuals first begin to accept responsibility for food planning, purchasing, and preparation. Policy and public health interventions must target those most at risk, namely, younger women and the socially deprived, whilst tackling the marketing of low-cost energy-dense foods at the expense of healthier options.

    Full Text Available Under the background of the wide application of condition-based maintenance (CBM in maintenance practice, the joint optimization of maintenance and spare parts inventory is becoming a hot research to take full advantage of CBM and reduce the operational cost. In order to avoid both the high inventory level and the shortage of spare parts, an appointment policy of spare parts is first proposed based on the prediction of remaining useful lifetime, and then a corresponding joint optimization model of preventive maintenance and spare parts inventory is established. Due to the complexity of the model, the combination method of genetic algorithm and Monte Carlo is presented to get the optimal maximum inventory level, safety inventory level, potential failure threshold, and appointment threshold to minimize the cost rate. Finally, the proposed model is studied through a case study and compared with both the separate optimization and the joint optimization without appointment policy, and the results show that the proposed model is more effective. In addition, the sensitivity analysis shows that the proposed model is consistent with the actual situation of maintenance practices and inventory management.

    2012-07-01

    Full Text Available Abstract The Village/Commune Safety Policy was launched by the Ministry of Interior of the Kingdom of Cambodia in 2010 and, due to a priority focus on “cleaning the streets”, has created difficulties for HIV prevention programs attempting to implement programs that work with key affected populations including female sex workers and people who inject drugs. The implementation of the policy has forced HIV program implementers, the UN and various government counterparts to explore and develop collaborative ways of delivering HIV prevention services within this difficult environment. The following case study explores some of these efforts and highlights the promising development of a Police Community Partnership Initiative that it is hoped will find a meaningful balance between the Village/Commune Safety Policy and HIV prevention efforts with key affected populations in Cambodia.

    Background Post-stroke Depression, Obstructive sleep apnea (OSA) and Cognitive impairment (“DOC”) are associated with greater mortality, worse recovery and poorer quality of life. Best practice recommendations endorse routine screening for each condition; yet, all are under-assessed, diagnosed and treated. We seek to determine the feasibility and validity of an integrated tool (“DOC” screen) to identify stroke clinic patients at high-risk of depression, OSA, and cognitive impairment. Methods All consecutive new referrals to a regional Stroke Prevention Clinic who were English-speaking and non-aphasic were eligible to be screened. Time for screen completion was logged. DOC screen results were compared to the neuropsychological battery and polysomnogram assessments using a modified receiver operator characteristic and area under the curve analysis. Data is reported to conform to STARD guidelines. Findings 1503 people were screened over 2 years. 89% of eligible patients completed the screen in 5 minutes or less (mean 4.2 minutes), less than half the time it takes to complete the Montreal Cognitive Assessment (MoCA). 437 people consented to detailed testing. Of those, 421 completed the Structured Clinical Interview for Depression within 3 months of screening, 387 completed detailed neuropsychological testing within 3 months, and 88 had overnight polysomnograms. Screening scores combined with demographic variables (age, sex, education, body mass index), had excellent validity compared to gold standard diagnoses: DOC-Mood AUC 0.90; DOC-Apnea AUC 0.80; DOC-Cog AUC 0.81. DOC screen scores can reliably categorize patients in to low-, intermediate- or high-risk groups for further action and can do so with comparable accuracy to more time-consuming screens. Conclusions Systematic screening of depression, obstructive sleep apnea, and cognitive impairment in 5 minutes or less is feasible and valid in a high volume stroke clinic using the DOC screen. The DOC screen may

    Systematic identification of evidence in health policy can be time-consuming and challenging. This study examines three questions pertaining to systematic reviews on obesity prevention policy, in order to identify the most efficient search methods: (1) What percentage of the primary studies selected for inclusion in the reviews originated in scholarly as opposed to gray literature? (2) How much of the primary scholarly literature in this topic area is indexed in PubMed/MEDLINE? (3) Which databases index the greatest number of primary studies not indexed in PubMed, and are these databases searched consistently across systematic reviews? We identified systematic reviews on obesity prevention policy and explored their search methods and citations. We determined the percentage of scholarly vs. gray literature cited, the most frequently cited journals, and whether each primary study was indexed in PubMed. We searched 21 databases for all primary study articles not indexed in PubMed to determine which database(s) indexed the highest number of these relevant articles. In total, 21 systematic reviews were identified. Ten of the 21 systematic reviews reported searching gray literature, and 12 reviews ultimately included gray literature in their analyses. Scholarly articles accounted for 577 of the 649 total primary study papers. Of these, 495 (76%) were indexed in PubMed. Google Scholar retrieved the highest number of the remaining 82 non-PubMed scholarly articles, followed by Scopus and EconLit. The Journal of the American Dietetic Association was the most-cited journal. Researchers can maximize search efficiency by searching a small yet targeted selection of both scholarly and gray literature resources. A highly sensitive search of PubMed and those databases that index the greatest number of relevant articles not indexed in PubMed, namely multidisciplinary and economics databases, could save considerable time and effort. When combined with a gray literature search and

    Full Text Available Abstract Background Population-based association studies are used to identify common susceptibility variants for complex genetic traits. These studies are susceptible to confounding from unknown population substructure. Here we apply a model-based clustering approach to our case-control study of stroke among young women to examine if self-reported ethnicity can serve as a proxy for genetic ancestry. Findings A population-based case-control study of stroke among women aged 15-49 identified 361 cases of first ischemic stroke and 401 age-comparable control subjects. Thirty single nucleotide polymorphisms (SNPs throughout the genome unrelated to stroke risk and with established ancestry-based allele frequency differences were genotyped in all participants. The Structure program was used to iteratively evaluate for K = 1 to 5 potential genetic-based subpopulations. Evaluating the population as a whole, the Structure output plateaued at K = 2 clusters. 98% of self-reported Caucasians had an estimated probability ≥50% of belonging to Cluster 1, while 94% of self-reported African-Americans had an estimated probability ≥50% of belonging to Cluster 2. Stratifying the participants by self-reported ethnicity and repeating the analyses revealed the presence of two clusters among Caucasians, suggesting that potential substructure may exist. Conclusions Among our combined sample of African-American and Caucasian participants there is no large unknown subpopulation and self-reported ethnicity can serve as a proxy for genetic ancestry. Ethnicity-specific analyses indicate that population substructure may exist among the Caucasian participants indicating that further studies are warranted.

  3. Environmental components of OCS policy committee recommendations regarding national oil spill prevention and response program

    The Exxon Valdez oil spill of March 24, 1989 resulted in thousands of pages of analytical reports assessing the environmental, organizational, legal, procedural, social, economic, and political aspects of the event. Even though the accident was a transportation incident, it had a major impact on the public and political perception of offshore oil operations. This caused the OCS Policy Committee, which advises the Secretary of the Interior and the Minerals Management Service on Outer Continental Shelf resource development and environmental matters, to undertake a review of the reports for the purpose of developing recommendations to the secretary for improvements in OCS operations that would insure maximum efforts to prevent spills and optimal ability to deal with any that occur. The Committee felt strongly that 'a credible national spill prevention and response program from both OCS and non-OCS oil spills in the marine environment is needed to create the political climate for a viable OCS program.' The report of the Committee described eight essential elements of this program; four of these focused on the environmental aspects of oil spills, calling for (1) adequate characterization of the marine and coastal environment, including both information and analysis, accessible to decision makers, (2) the capacity to restore economic and environmental resources as quickly as possible if damage occurs, (3) a mechanism for research on oil spill impacts, and (4) a meaningful role for all interested and responsible parties, including the public, in as many of these activities as possible, from spill prevention and contingency planning to environmental oversight of ongoing operations and participation in clean-up and restoration activities

    2010-12-01

    Full Text Available Abstract Background Despite lack of outward signs, most individuals after non-disabling stroke (NDS and transient ischemic attack (TIA have significant cardiovascular and cerebrovascular disease and are at high risk of a major stroke, hospitalization for other vascular events, or death. Most have multiple modifiable risk factors (e.g., hypertension, physical inactivity, hyperlipidaemia, diabetes, tobacco consumption, psychological stress. In addition, accelerated rates of depression, cognitive decline, and poor quality of sleep have been reported following TIA, which correlate with poor functional outcomes and reduced quality of life. Thus, NSD and TIA are important warning signs that should not be overlooked. The challenge is not unlike that facing other 'silent' conditions - to identify a model of care that is effective in changing people's current behaviors in order to avert further morbidity. Methods/Design A single blind, randomized controlled trial will be conducted at two sites to compare the effectiveness of a program of rehabilitative exercise and education versus usual care in modifying vascular risk factors in adults after NDS/TIA. 250 adults within 90 days of being diagnosed with NDS/TIA will be randomly allocated to a 12-week program of exercise and education (PREVENT or to an outpatient clinic assessment and discussion of secondary prevention recommendations with return clinic visits as indicated (USUAL CARE. Primary outcome measures will include blood pressure, waist circumference, 12-hour fasting lipid profile, and 12-hour fasting glucose/hemoglobin A1c. Secondary measures will include exercise capacity, walking endurance, physical activity, cognitive function, depression, goal attainment and health-related quality of life. Outcome assessment will be conducted at baseline, post-intervention, and 6- and 12-month follow-ups. Direct health care costs incurred over one year by PREVENT versus USUAL CARE participants will also be

    Legislation is an effective strategy for reducing road-related fatalities and injuries. Public opinion can be an impetus for passing new laws and can affect the success of their implementation, but little is known about the current state of public opinion toward existing and proposed road-related policies in the United States. This review describes the scope and results of research on public support for state- and local-level evidence-based motor vehicle- and bicycle-related policies. We identify gaps in our understanding of public support for these policies. Published U.S. literature and all reports from the NHTSA from the past decade (2003-2012) were searched for data on opinions about existing or proposed policies related to motor vehicle or bicycle injury prevention. Twenty-six studies fulfilled the inclusion criteria. In all, studies reported public opinion about 7 injury prevention topic areas: all-terrain vehicles (n = 1), automated enforcement with red light and speed cameras (n = 5), distracted driving (n = 4), drinking and driving (n = 5), graduated driver licensing (n = 7), helmets (n = 7), and seat belts (n = 4). Twenty-three studies focused only on one topic, and 3 sought public opinion about multiple topic areas. The studies revealed generally high levels of support for injury prevention policies in all topic areas. Fifteen studies collected information from national samples, and only 7 studies reported data from the state (n = 5) or local (n = 2) level. There is a relatively small evidence base on public opinion related to motor vehicle- and bicycle-related evidence-based policies; even less is less known for state- or county-specific policies. The findings of this review suggest that the public's opinion toward injury prevention legislation is generally favorable. This information can be used to communicate with the media and policy makers to reinforce the need for effective policy solutions to continuing motor vehicle injury problems. More research

    Full Text Available Stroke is the leading cause of death in many countries of Latin America. Population studies are necessary in this region. Objectives: To evaluate the prevalence of stroke and its risk factors in a population of vulnerable communities of southern Brazil. Methods: Population-based crosssectional study with systematic sampling. Individuals aged 20 and over were included (n=3,391. Individuals with previous diagnosis of stroke or identified by a validate stroke questionnaire were compared with those without stroke in many variables. Results: 285 individuals (8.4% had previous stroke. The group without stroke showed greater average of years of study than the group with stroke (p≪0.001. Multivariable analysis identified as risk factors for stroke (p≪0.05: age from 40 to 59, age from 60 to 79, widowhood, present smoking, previous smoking, hypertension and ischemic heart disease. Conclusion: The findings in this population indicate the need of preventive cost-effective public health policies in Brazil.

    The U.S. Preventive Services Task Force (USPSTF) provides independent, objective, and scientifically rigorous recommendations for clinical preventive services. A primary concern is to avoid even the appearance of members having special interests that might influence their ability to judge evidence and formulate unbiased recommendations. The conflicts of interest policy for the USPSTF is described, as is the formal process by which best practices were incorporated to update the policy. The USPSTF performed a literature review, conducted key informant interviews, and reviewed conflicts of interest policies of ten similar organizations. Important findings included transparency and public accessibility; full disclosure of financial relationships; disclosure of non-financial relationships (that create the potential for bias and compromise a member's objective judgment); disclosure of family members' conflicts of interests; and establishment of appropriate reporting periods. Controversies in best practices include the threshold of financial disclosures, ease of access to conflicts of interest policies and declarations, vague definition of non-financial biases, and request for family members' conflicts of interests (particularly those that are non-financial in nature). The USPSTF conflicts of interest policy includes disclosures for immediate family members, a clear non-financial conflicts of interest definition, long look-back period and application of the policy to prospective members. Conflicts of interest is solicited from all members every 4 months, formally reviewed, adjudicated, and made publicly available. The USPSTF conflicts of interest policy is publicly available as part of the USPSTF Procedure Manual. A continuous improvement process can be applied to conflicts of interest policies to enhance public trust in members of panels, such as the USPSTF, that produce clinical guidelines and recommendations.

    Recently, legislative initiatives to prevent sex crime recidivism include the passage of child safety zones (also called loitering zones) that prohibit sex offenders from lingering near places where children congregate. The ability of policies such as these or residence restrictions to curb sexual recidivism depends on the empirical reality of sex offender perpetration patterns. As such, the current study sought to examine locations where sex offenders first come into contact with their victims and whether sex crime locations differ among those who perpetrate offenses against children as compared to those who perpetrate offenses against adults. Further, this study examined actuarial risk scores and recidivism rates among offenders who met victims in child-dense public locations to determine if these offenders are more at risk of re-offense. Descriptive analyses, based on archival sex offender file review (N=1557), revealed that offenders primarily cultivated their offenses in private residential locations (67.0%); relatively few offenders (4.4%) met their victims in child-dense public locations. Further, offenders who perpetrated crimes against children were more likely to meet victims within a residence, while those who perpetrate crimes against adults were more likely to encounter victims in a more public type of location (e.g., bar, workplace). Though only 3.7% of all offenders in this sample sexually recidivated, those who recidivated were more likely to have met their victim in a child-dense public location than those who did not recidivate. Current sex crime policies that focus only on where offenders live may fail to focus on where offenders go and, further, may misdirect efforts away from the place where sex crimes most often occur, namely, in the home.

    In today's global environment, technology is constantly evolving. Being able to stay up-to-date with the very latest technological advances can be extremely hard to accomplish. As a result of these changes and developments in technology, which often come unexpectedly, consumers are frequently tempted to update their devices to the very latest model. The result is that the life cycle of a product is becoming shorter and shorter than before. Manufacturers attempt to respond to consumers' concerns involving environmental issues as well as the more governmentally stringent environmental legislations by establishing facilities which include the minimization of the totality of waste relocated to landfills by recovering materials and components from returned, or End-Of-Life products and reuse them to build a remanufactured product, and/or novel components. With the rapid growth of interest in remanufactured products' market, offering warranty for remanufactured products and components is becoming a necessity for remanufacturer in order to meet customers' requirement and as a marketing mechanism. During that process, maintenance policies are of great importance in order to reduce the warranty cost on the remanufacturer. In this paper, an optimization simulation model for remanufactured items sold with one-dimensional non-renewing money-back guarantee (MBG) warranty policy is proposed from the view of remanufacturer, in which, an End-Of-Life product is subjected to upgrade action at the end of its past life and during the warranty period, preventive maintenance actions are carried out when the remaining life of the product reaches a pre-specified value so that the remanufacturer's expected profit can be maximized. Finally, a numerical example and design of experiment analysis are provided to demonstrate the proposed approach.

    To date, few tools assist policy makers and practitioners in understanding and conveying the implementation costs, potential impacts, and value of policy and environmental changes to address healthy eating, active living, and childhood obesity. For the Evaluation of Healthy Kids, Healthy Communities (HKHC), evaluators considered inputs (resources and investments) that generate costs and savings as well as benefits and harms related to social, economic, environmental, and health-related outcomes in their assessment of 49 HKHC community partnerships funded from 2009 to 2014. Using data collected through individual and group interviews and an online performance monitoring system, evaluators created a socioecological framework to assess investments, resources, costs, savings, benefits, and harms at the individual, organizational, community, and societal levels. Evaluators customized frameworks for 6 focal strategies: active transportation, parks and play spaces, child care physical activity standards, corner stores, farmers' markets, and child care nutrition standards. To illustrate the Value Frameworks, this brief highlights the 38 HKHC communities implementing at least 1 active transportation strategy. Evaluators populated this conceptual Value Framework with themes from the strategy-specific inputs and outputs. The range of factors corresponding to the implementation and impact of the HKHC community partnerships are highlighted along with the inputs and outputs. The Value Frameworks helped evaluators identify gaps in current analysis models (ie, benefit-cost analysis, cost-effectiveness analysis) as well as paint a more complete picture of value for potential obesity prevention strategies. These frameworks provide a comprehensive understanding of investments needed, proposed costs and savings, and potential benefits and harms associated with economic, social, environmental, and health outcomes. This framing also allowed evaluators to demonstrate the interdependence

    Purpose Research of employer policies and practices to manage and prevent disability spans many disciplines and perspectives, and there are many challenges related to stakeholder collaboration, data access, and interventions. The purpose of this article is to synthesize the findings from a conference and year-long collaboration among a group of invited researchers intended to spur new research innovations in this field. Methods A multidisciplinary team of 26 international researchers with published research in employer-based disability management or related fields were invited to attend a 3-day conference in Hopkinton, Massachusetts, USA. The conference goals were to review the status of current research of workplace disability management and prevention, examine its relevance for employer decision-making, compare conceptual frameworks or theoretical perspectives, and recommend future research directions. In this paper, we summarize key points from the 6 resulting papers, compare them with an earlier 2005 conference on improving return-to-work research, and conclude with recommendations for further overarching research directions. Results/Conclusion In comparison with the 2005 conference, a greater emphasis was placed on organizational and social factors, employer roles and responsibilities, methods of implementation, non-clinical approaches, and facilitating stay-at-work as well as return-to-work. A special panel of employer consultants and representatives who were featured at the 2015 conference reinforced the importance of organizational culture, leadership style, and financial decision-making strategies at the employer level. Based on the conference proceedings, we recommend that future research in this area should strive for: (a) broader inclusion of workers and workplaces; (b) attention to multilevel influences in the workplace; (c) a focus on social as well as physical aspects of work; (d) earlier employer collaboration efforts; (e) more attention to

  13. Addressing policy needs for prevention and control of type 2 diabetes in India.

    India carries nearly one-fifth of the global burden of diabetes cases, the majority of which are of type 2 diabetes. Recognising the need for controlling diabetes, the Government of India has initiated a national level programme for prevention and control of diabetes along with other non-communicable diseases in 2008. Despite being piloted and implemented, there is hardly any published literature about the national level situation of diabetes and its control efforts. The present article is written with the aim to fill this gap to some extent and to provide a situational analysis of the diabetes problem in India in a holistic way, addressing policy needs for the national programme. It focuses on three main areas, namely, awareness of diabetes, costs of drugs for its treatment and healthcare-system related issues. It argues that poor coverage and weak implementation of the national level programme are major forces that push patients to seek help in the weakly regulated private sector. Approaching the private sector is likely to increase the cost of care, which in turn can lead to an increased financial burden for patients and their families due to factors such as patients' lack of awareness about diabetes, poor drug price regulation and prescriptions including combinations and/or patented products of medicines used for treating diabetes by the private sector. This article addresses several needs such as strengthening the national programme and increasing its reach to unreached districts, exerting drug price regulation and implementing community-based participatory programmes for prevention and management of type 2 diabetes. It also underscores a need for piloting and implementing a robust national level electronic reporting system for diabetes programmes. © Royal Society for Public Health 2015.

    While a large body of work documents the interconnections between oral health and obesity, less is known about the role that oral health professionals and organizations play to prevent childhood obesity, especially by influencing children's consumption of sugar-sweetened beverages (SSBs). This review identifies efforts by oral health professionals and organizations to influence such policy and advocacy, while informing future opportunities to leverage and expand on existing efforts. A scoping review of peer-reviewed literature and a web-based review of oral health policy and advocacy initiatives addressing prevention of obesity and reducing children's consumption of SSBs were conducted. Of 30 unique references identified, four peer-reviewed and seven non-peer-reviewed references met selection criteria. Qualitative and quantitative data were extracted using a priori determined headings. Findings suggest a strong role for oral health professionals in preventing childhood obesity and reducing children's consumption of SSBs; however, only a few national, state, and local oral-health-advocacy and -policy efforts were identified, such as policy statements by national associations, state and local education campaigns, and clinical guidelines. Evidence was limited on the role of oral health professionals in influencing broader communitywide advocacy and policy efforts such as soda taxation and limiting SSB consumption in schools. This review provides an emerging evidence base to support growing recognition among oral health professionals of their dual role in preventing childhood obesity and dental caries by targeting SSB consumption. It also identifies opportunities for oral health professionals to build on initial efforts to more proactively influence future policy and advocacy. © 2017 American Association of Public Health Dentistry.

    Understanding the genetic architecture of cerebrovascular disease holds promise of novel stroke prevention strategies and therapeutics that are both safe and effective. Apart from a few single-gene disorders associated with cerebral ischemia or intracerebral hemorrhage, stroke is a complex genetic phenotype that requires careful ascertainment and robust association testing for discovery and validation analyses. The recently uncovered shared genetic contribution between clinically manifest stroke syndromes and closely related intermediate cerebrovascular phenotypes offers effective and efficient approaches to complex trait analysis.

    Lifestyle modification programs have improved the achievement of risk factor targets in a variety of clinical settings, including patients who have previously suffered a stroke or transient ischemic attack and those with multiple risk factors. Stenting Aggressive Medical Management for Prevention of Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) was the first vascular disease prevention trial to provide a commercially available lifestyle modification program to enhance risk factor control. We sought to determine the relationship between compliance with this program and risk factor control in SAMMPRIS. SAMMPRIS aggressive medical management included a telephonic lifestyle modification program provided free of charge to all subjects (n = 451) during their participation in the study. Subjects with fewer than 3 expected lifestyle-coaching calls were excluded from these analyses. Compliant subjects (n = 201) had  greater than or equal to 78.5% of calls (median % of completed/expected calls). Noncompliant subjects (n = 200) had less than 78.5% of calls or refused to participate. Mean risk factor values or % in-target for each risk factor was compared between compliant versus noncompliant subjects, using t tests and chi-square tests. Risk factor changes from baseline to follow-up were compared between the groups to account for baseline differences. Compliant subjects had better risk factor control throughout follow-up for low-density lipoprotein, systolic blood pressure (SBP), hemoglobin A1c (HgA1c), non-high-density lipoprotein, nonsmoking, and exercise than noncompliant subjects, but there was no difference for body mass index. After adjusting for baseline differences between the groups, compliant subjects had a greater change from baseline than noncompliant subjects for SBP did at 24 months and HgA1c at 6 months. SAMMPRIS subjects who were compliant with the lifestyle modification program had better risk factor control during the study for almost

    Epidemiological and family studies have provided evidence on the role of genetic factors in stroke, particularly in stroke occurring at young age. However, despite its impact, young stroke continues to be understudied. This article reviews the existing literature on the most investigated monogenic disorders (CADASIL, Fabry disease, MELAS, RVCL, COL4A1, Marfan and Ehlers-Danlos syndromes) causing stroke in young and a number of candidate genes associated with stroke occurring in patients younger than 50 years. Although our study failed in identifying strong and reliable associations between specific genes and young stroke, our detailed literature revision on the field allowed us to compile a panel of genes possibly generating a susceptibility to stroke, which could be a starting point for future research. Since stroke is a potentially preventable disease, the identification of genes associated with young stroke may promote novel prevention strategies and allow the identification of therapeutic disease targets.

    The majority of strokes, both ischaemic and haemorrhagic, are attributable to a relatively small number of risk factors which are readily manageable in primary care setting. Implementation of best-practice recommendations for risk factor management is calculated to reduce stroke recurrence by around 80%. However, risk factor management in stroke survivors has generally been poor at primary care level. A model of care that supports long-term effective risk factor management is needed. To determine whether the model of Integrated Care for the Reduction of Recurrent Stroke (ICARUSS) will, through promotion of implementation of best-practice recommendations for risk factor management reduce the combined incidence of stroke, myocardial infarction and vascular death in patients with recent stroke or transient ischaemic attack (TIA) of the brain or eye.

    Obesity is currently a global public health problem. Obesity in early life increases the risk of long-term energy imbalance and adult obesity and its comorbidities, type 2 diabetes, and cardiovascular disease. Since infancy and childhood are critical periods for the adoption of food preferences and physical activity, prevention strategies must intervene in these early periods to promote healthy habits and reduce risk behaviors. Trends in the prevalence of childhood obesity and overweight in Spain have continuously increased in the last three decades. Obesity and overweight currently affect 15 and 20% of Spanish children, respectively, and these percentages are among the highest in Europe. Childhood obesity is determined by social and economic factors pertaining to sectors other than the health system, such as advertising, the built environment, education and the school environment, transportation and the food environment. Following the Health in All Policies (HiAP) approach, the authors identified a series of multisector policy changes that may help to prevent and control the current rising trend of childhood obesity in Spain. The HiAP approach acknowledges that social factors including socioeconomic status, gender differences and the work-life balance are important to develop effective policy changes in the prevention of childhood obesity. A key to success in the prevention of childhood obesity in Spain through policy changes will depend on the ability to establish a policy with the explicit and primary goal of improving health outcomes, despite the anticipated resistance from various sectors and stakeholders.

    Full Text Available The source of conflict between Supermarkets and Wet-markets arise from the use of market power and economies of scale by one group against the other. This study explores the tensions that exist between modern retailers and their traditional counterparts as a result of the influx of supermarkets in Ghana. The main objective of the study is to compare attributes related to the control of access to consumers by the Supermarket and the Wet-market. In this study, the dot-survey approach of Rapid Market Assessment Technique was used to elicit information from 438 respondents at the Madina market (wet-market and Melcom (supermarket over a period of two weeks and Wilcoxon-Mann-Whitney (WMW comparison test and descriptive statistics were employed for the analysis. The results revealed that consumers patronise the supermarkets for convenience and the wet-market for freshness of product. Their purchasing decisions were affected by their level of education and product selections of the retailer. The highly educated preferred to shop at the Supermarket instead of the Wet-market; however, over 50% of respondents preferred the wet-market for fresh food products and the supermarket for non-food items. Each retailer receives its fair share of purchases from its loyal customers, therefore the revolution arising from the supermarket influx in Ghana has not yet resulted into conflict between supermarkets and their traditional counterparts, though it is inevitable if nothing is done to prevent it from happening. To avoid the conflict, it is recommended that policies should be instituted to (i improve the market infrastructures and shopping environment in the Wet-markets, (ii give tax concession to modern retailers who source products from local farmers and small-scale processors, (iii enable traditional retailers position themselves on the fringe and co-exist with modern retailers and (iv enforce public standards with regards to food safety laws in the traditional

    Despite ongoing investments to improve the obesogenic environments of childcare settings, little is known regarding how these services have changed their physical activity and nutrition-promoting practices. This study aims to describe changes in the proportion of Australian childcare services that have adopted best-practice healthy eating and physical activity practices between 2006 and 2013 and to assess whether adoption varied by socio-economic status and locality. A randomly selected sample of nominated supervisors (n = 358) from childcare services located in New South Wales, Australia, participated in a telephone survey in 2006, 2009, 2010 and 2013. Supervisors reported on their service's adoption of six practices: (i) having written nutrition and physical activity policies; (ii) staff trained in physical activity and nutrition in the past year; (iii) scheduled time for fundamental movement skills and (iv) outdoor play; (v) weekly or less screen time opportunities; and (vi) serving only non-sweetened beverages. A significant increase in the prevalence of services adopting all but one practice, between 2006 and 2013 was identified. Ninety one percent of services adopted four or more practices, a significant increase from 38% in 2006. There were no differences in the proportion of services adopting each practice by locality and socio-economic status. Government investment in obesity prevention programmes can equitably improve childcare service's adoption of healthy eating and physical activity promoting practices on a jurisdiction-wide basis. The establishment of a routine system to monitor adoption of a broader range of practices by childcare services is warranted. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Full Text Available This paper will address the application of legal measures as part of the policy of corruption prevention in the public sphere. At present, corruption offenses have become a very dangerous phenomenon for the stability and security of societies, undermining the institutions and values of democracy, ethical values and justice, and jeopardizing the essential development and the rule of law. Knowing that these criminal offenses carry a high social risk and are conducted with high professionalism from people who have the state power, a greater focus should be placed on its prevention. Naturally, the criminal sanctions against criminal acts of corruption have their positive effect, punitive and preventive, but these are the last measures that the state should use. The state of Kosovo in an effort to prevent corruption, has established in legal terms an advanced legislation in accordance with international laws and comparable to developed countries.

    GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non-vitamin K antagonist oral anticoagulant (NOAC), became available. This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase 1. During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients' baseline characteristics. Atrial fibrillation disease characteristics, medical outcomes, and concomitant diseases and medications were collected.
