Because human and financial resources are limited, health efforts must focus on prevention strategies that yield the most benefit for the investment. Many current strategies identified in the literature offer opportunities to promote health at a reasonable cost. To present a literature-based review of evidence demonstrating that prevention can be an effective and wise use of resources through CDC's An Ounce of Prevention ... What Are the Returns? Second Edition. Systematic review of cost-effectiveness literature for a selected group of prevention strategies. Prevention strategies relevant to the U.S. population. Data indicate that the health conditions considered can be addressed through prevention strategies that are either cost effective or cost saving. An Ounce of Prevention ... What Are the Returns? Second Edition can be used to conveniently access information on prevention strategies, the diseases and injuries they address, and their cost effectiveness. It also complements other comprehensive prevention guides. However, limitations of the available cost-effectiveness studies indicate that standardized procedures should be followed for studies of all recommended prevention strategies. Researchers must standardize review procedures to improve both the quality and comparability of studies.

Due to the arrival of multi-valent HPV vaccines, it is more and more important to have a better understanding of the relationship between vaccination and screening programmes. This review aimed to: (1) collect published evidence on the cost-effectiveness profile of different HPV prevention strategies and, in particular, those combining vaccination with changes in screening practices; (2) explore the cost-effectiveness of alternative preventive strategies based on screening and vaccination. A systematic literature review was conducted in order to identify the relevant studies regarding the cost-effectiveness of prevention strategies against HPV infection. Analysis comparing the modelling approaches between studies was made along with an assessment of the magnitude of impact of several factors on the cost-effectiveness of different screening strategies. A total of 18 papers were quantitatively summarised within the narrative. A high degree of heterogeneity was found in terms of how HPV prevention strategies have been assessed in terms of their economic and epidemiological impact, with variation in screening practice and valence of HPV vaccination found to have large implications in terms of cost-effectiveness. This review demonstrated synergies between screening and vaccination. New prevention strategies involving multi-valence vaccination, HPV DNA test screening, delayed commencement and frequency of screening could be implemented in the future. Strategies implemented in the future should be chosen with care, and informed knowledge of the potential impact of all possible prevention strategies. Highlighted in this review is the difficulty in assessing multiple strategies. Appropriate modelling techniques will need to be utilised to assess the most cost-effective strategies.

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.

To update the current injury prevention strategy evidence base for making recommendations to prevent physical training-related musculoskeletal injury. We conducted a systematic review to update the evidence base on injury prevention strategies for military personnel. Literature was systematically searched and extracted from five databases, and reported according to PRISMA guidelines. Sixty one articles meeting the inclusion criteria and published during the period 2008-2015 were selected for systematic review. The retrieved articles were broadly categorised into six injury prevention strategies; (1) conditioning, (2) footwear modifications, (3) bracing, (4) physical activity volume, (5) physical fitness, and (6) leadership/supervision/awareness. The majority of retrieved articles (n=37 (of 61) evaluated or systematically reviewed a conditioning intervention of some nature. However, the most well-supported strategies were related to reducing physical activity volume and improving leadership/supervision/awareness of injuries and injury prevention efforts. Several injury prevention strategies effectively reduce musculoskeletal injury rates in both sexes, and many show promise for utility with military personnel. However, further evaluation, ideally with prospective randomised trials, is required to establish the most effective injury prevention strategies, and to understand any sex-specific differences in the response to these strategies.

The fast increasing stroke burden across all countries of the world suggests that currently used primary stroke and cardiovascular disease (CVD) prevention strategies are not sufficiently effective. In this article, we overview the gaps in, and pros and cons of, population-wide and high-risk prevention strategies. We suggest that motivating and empowering people to reduce their risk of having a stroke/CVD by using increasingly used smartphone technologies would bridge the gap in the population-wide and high-risk prevention strategies and reduce stroke/CVD burden worldwide. We emphasise that for primary stroke prevention to be effective, the focus should be shifted from high-risk prevention to prevention at any level of CVD risk, with the focus on behavioural risk factors. Such a motivational population-wide strategy could open a new page in primary prevention of not only stroke/CVD but also other non-communicable disorders worldwide. PMID:28589034

Prevention of hospital-acquired pneumonia: European perspective.

Several preventive measures for VAP have been empirically tested. There is clear evidence that antibiotic-containing preventive strategies, such as SDD and oropharyngeal decontamination, are very effective in different patient populations. Selection of antibiotic resistance remains the major disadvantage of these strategies, however, limiting its applicability in settings with high levels of antibiotic resistance. This probably precludes the use of these strategies in many American settings, but may allow their use in European countries with much lower endemic levels of resistance. There is little evidence that systemic prophylaxis is effective for the prevention of VAP, and initial studies were associated with resistance problems. Of the non antibiotic-containing preventive strategies, subglottic aspiration was effective in several studies, whereas other strategies, such as immunonutrition with glutamine or the semirecumbent patient position, were effective in single studies. All these studies were executed in European ICUs. For these interventions, more data are needed on the generalizability, feasibility, and cost effectiveness. Few data support the use of sucralfate for stress ulcer prophylaxis and modulation of enteral nutrition practices as preventive measures for VAP.

Efficient immunization strategies to prevent financial contagion

Many immunization strategies have been proposed to prevent infectious viruses from spreading through a network. In this work, we study efficient immunization strategies to prevent a default contagion that might occur in a financial network. An essential difference from the previous studies on immunization strategy is that we take into account the possibility of serious side effects. Uniform immunization refers to a situation in which banks are ``vaccinated'' with a common low-risk asset. The riskiness of immunized banks will decrease significantly, but the level of systemic risk may increase due to the de-diversification effect. To overcome this side effect, we propose another immunization strategy, called counteractive immunization, which prevents pairs of banks from failing simultaneously. We find that counteractive immunization can efficiently reduce systemic risk without altering the riskiness of individual banks.

This systematic review examined 140 outcome evaluations of primary prevention strategies for sexual violence perpetration. The review had two goals: 1) to describe and assess the breadth, quality, and evolution of evaluation research in this area; and 2) to summarize the best available research evidence for sexual violence prevention practitioners by categorizing programs with regard to their evidence of effectiveness on sexual violence behavioral outcomes in a rigorous evaluation. The majority of sexual violence prevention strategies in the evaluation literature are brief, psycho-educational programs focused on increasing knowledge or changing attitudes, none of which have shown evidence of effectiveness on sexually violent behavior using a rigorous evaluation design. Based on evaluation studies included in the current review, only three primary prevention strategies have demonstrated significant effects on sexually violent behavior in a rigorous outcome evaluation: Safe Dates (Foshee et al., 2004); Shifting Boundaries (building-level intervention only, Taylor, Stein, Woods, Mumford, & Forum, 2011); and funding associated with the 1994 U.S. Violence Against Women Act (VAWA; Boba & Lilley, 2009). The dearth of effective prevention strategies available to date may reflect a lack of fit between the design of many of the existing programs and the principles of effective prevention identified by Nation et al. (2003). PMID:29606897

The Division of Violence Prevention within CDC’s National Center for Injury Prevention and Control recently undertook a systematic review of primary prevention strategies for sexual violence (SV) perpetration. This review identified the lack of community-level strategies to prevent SV as a critical gap in the literature. Community-level strategies function by modifying the characteristics of settings (e.g., schools, workplaces, neighborhoods) that increase the risk for violence victimization and perpetration. Identification of evidence-based strategies at the community level would allow implementation of ecologic approaches to SV prevention with a greater potential for reducing the prevalence of SV perpetration. The field will face several challenges in identifying and evaluating the effectiveness of promising community-level strategies to prevent SV. These challenges include limited knowledge of community-level and societal-level risk factors for SV, a lack of theoretical or empirical guidance in the SV literature for identification of promising community-level approaches, and challenges in evaluating SV outcomes at the community level. Recognition of these challenges should guide future research and foster dialogue within the SV prevention field. The development and evaluation of community-level approaches to SV prevention represent a vital and logical next step toward the implementation of effective, multilevel prevention efforts and a population-level reduction in the prevalence of SV.

In the past 25 years, the field of HIV prevention research has been transformed repeatedly. Today, effective HIV prevention requires a combination of behavioral, biomedical, and structural intervention strategies. Risk of transmitting or acquiring HIV is reduced by consistent male and female-condom use, reductions in concurrent and/or sequential sexual and needle-sharing partners, male circumcision, and treatment with antiretroviral medications. At least 144 behavioral prevention programs have been found effective in reducing HIV transmission acts; however, scale up of these programs has not occurred outside of the United States. A series of recent failures of HIV-prevention efficacy trials for biomedical innovations such as HIV vaccines, treating herpes simplex 2 and other sexually transmitted infections, and diaphragm and microbicide barriers highlights the need for behavioral strategies to accompany biomedical strategies. This challenges prevention researchers to reconceptualize how cost-effective, useful, realistic, and sustainable prevention programs will be designed, delivered, tested, and diffused. The next generation of HIV prevention science must draw from the successes of existing evidence-based interventions and the expertise of the market sector to integrate preventive innovations and behaviors into everyday routines.

"Prevention might be better than treatment in cancer treatment" is brief conclusion drawn from war on cancer through National Cancer Act of 1971 by U.S. President Richard Nixon. However, the clinical practice of chemoprevention is still in its infancy in spite of a wealth of data showing its effectiveness in experimental animals as well as in vitro mechanism research. Recent advances in either high throughput analysis including cancer genomes and tailored medicine or molecular targeted therapeutics, preventive strategies also should be changes as previous preventive strategies including phytoceuticals, life-style modification, and some empirical agents. Furthermore, molecular targeted therapeutics achieved high goal of effectiveness under the concept of therapeutic or preventive "synthetic lethality", of which extended application can be included within the scope of chemoprevention. Here, we will summarize several recent advances in chemopreventive strategy objected to justify optimism that chemoprevention will be an effective approach for the control of human cancer. siTRP (short-term intervention to revert premalignancy) strategy will be introduced for cancers in gastroenterology.

Pressure ulcers are common in many care settings, with adverse health outcomes and high treatment costs. We evaluated the cost-effectiveness of evidence-based strategies to improve current prevention practice in long-term care facilities. We used a validated Markov model to compare current prevention practice with the following 4 quality improvement strategies: (1) pressure redistribution mattresses for all residents, (2) oral nutritional supplements for high-risk residents with recent weight loss, (3) skin emollients for high-risk residents with dry skin, and (4) foam cleansing for high-risk residents requiring incontinence care. Primary outcomes included lifetime risk of stage 2 to 4 pressure ulcers, quality-adjusted life-years (QALYs), and lifetime costs, calculated according to a single health care payer's perspective and expressed in 2009 Canadian dollars (Can$1 = US$0.84). Strategies cost on average $11.66 per resident per week. They reduced lifetime risk; the associated number needed to treat was 45 (strategy 1), 63 (strategy 4), 158 (strategy 3), and 333 (strategy 2). Strategy 1 and 4 minimally improved QALYs and reduced the mean lifetime cost by $115 and $179 per resident, respectively. The cost per QALY gained was approximately $78 000 for strategy 3 and $7.8 million for strategy 2. If decision makers are willing to pay up to $50 000 for 1 QALY gained, the probability that improving prevention is cost-effective is 94% (strategy 4), 82% (strategy 1), 43% (strategy 3), and 1% (strategy 2). The clinical and economic evidence supports pressure redistribution mattresses for all long-term care residents. Improving prevention with perineal foam cleansers and dry skin emollients appears to be cost-effective, but firm conclusions are limited by the available clinical evidence.

Early-onset Group B haemolytic streptococcus infection (EOGBS) is an important cause of neonatal morbidity and mortality in the first week of life. Primary prevention of EOGBS is possible with intra-partum antibiotic prophylaxis (IAP.) Different prevention strategies are used internationally based on identifying pregnant women at risk, either by screening for GBS colonisation and/or by identifying risk factors for EOGBS in pregnancy or labour. A theoretical cost-effectiveness study has shown that a strategy with IAP based on five risk factors (risk-based strategy) or based on a positive screening test in combination with one or more risk factors (combination strategy) was the most cost-effective approach in the Netherlands. IAP for all pregnant women with a positive culture in pregnancy (screening strategy) and treatment in line with the current Dutch guideline (IAP after establishing a positive culture in case of pre-labour rupture of membranes or preterm birth and immediate IAP in case of intra-partum fever, previous sibling with EOGBS or GBS bacteriuria), were not cost-effective. Cost-effectiveness was based on the assumption of 100% adherence to each strategy. However, adherence in daily practice will be lower and therefore have an effect on cost-effectiveness. The aims are to: a.) implement the current Dutch guideline, the risk-based strategy and the combination strategy in three pilot regions and b.) study the effects of these strategies in daily practice. Regions where all the care providers in maternity care implement the allocated strategy will be randomised. Before the introduction of the strategy, there will be a pre-test (use of the current guideline) involving 105 pregnant women per region. This will be followed by a post-test (use of the allocated strategy) involving 315 women per region. The outcome measures are: 1.) adherence to the specific prevention strategy and the determinants of adherence among care providers and pregnant women, 2.) outcomes in pregnant women and their babies and 3.) the costs of each strategy in relation to the effects. This study will provide recommendations for the implementation of the most cost-effective prevention strategy for EOGBS in the Netherlands on the basis of feasibility in daily practice.

Prevention of sport injuries is crucial to maximise the health and societal benefits of a physically active lifestyle. To strengthen the translation and implementation of the available evidence base on effective preventive measures, a range of potentially relevant strategies should be considered. Our aim was to identify and categorise intervention strategies for the prevention of acute sport injuries evaluated in the scientific literature, applying the Haddon matrix, and identify potential knowledge gaps. Five electronic databases were searched (PubMed, EMBASE, SPORTDiscus, CINAHL, Cochrane) for studies that evaluated the effect of interventions on the occurrence of acute sport injuries. Studies were required to include a control group/condition, prospective data collection, and a quantitative injury outcome measure. A total of 155 studies were included, mostly randomised controlled trials (43%). The majority of studies (55%) focussed on strategies requiring a behavioural change on the part of athletes. Studies predominantly evaluated the preventive effect of various training programmes targeted at the 'pre-event' phase (n = 73) and the use of equipment to avoid injury in the 'event phase' (n = 29). A limited number of studies evaluated the preventive effect of strategies geared at rules and regulations (n = 14), and contextual modifications (n = 18). Studies specifically aimed at preventing re-injuries were a minority (n = 8), and were mostly related to ankle sprains (n = 5). Valuable insight into the extent of the evidence base of sport injury prevention studies was obtained for 20 potential intervention strategies. This approach can be used to monitor potential gaps in the knowledge base on sport injury prevention.

Recently, authors have theorized that invasive species prevention is more cost-effective than control in protecting ecosystem services. However, quantification of the effectiveness of prevention is rare because experiments at field scales are expensive or infeasible. We therefore used structured expert judgment to quantify the efficacy of 17 proposed strategies to prevent Asian carp invasion of the Laurentian Great Lakes via the hydrologic connection between the Mississippi and Great Lakes watersheds. Performance-weighted expert estimates indicated that hydrologic separation would prevent 99% (95,100; median, 5th and 95th percentiles) of Asian carp access, while electric and acoustic-bubble-strobe barriers would prevent 92% (85,95) and 92% (75,95), respectively. For all other strategies, estimated effectiveness was lower, with greater uncertainty. When potential invasions by other taxa are considered, the effectiveness of hydrologic separation increases relative to strategies that are effective primarily for fishes. These results could help guide invasive species management in many waterways globally.

To review the current state of breast cancer prevention from primary prevention through survivorship, highlight cross-cutting issues, and discuss strategies for clinical integration and future research. Published articles between 1985 and 2015 and original research. Cancer risk persists across the lifespan. Interprofessional strategies to reduce morbidity and mortality from cancer include primary, secondary, and tertiary prevention (survivorship). Prevention strategies across the cancer care continuum are cross-cutting and focus on measures to: prevent the onset of disease, identify and treat asymptomatic persons who have already developed risk factors or preclinical disease, and restore function, minimize the negative effects of disease, and prevent disease-related complications. Oncology nurses and advanced practice nurses are vital in the delivery of breast cancer prevention strategies. Published by Elsevier Inc.
Strategies to prevent injury in adolescent sport: a systematic review
Abernethy, Liz; Bleakley, Chris
2007-01-01
This systematic review set out to identify randomised controlled trials and controlled intervention studies that evaluated the effectiveness of preventive strategies in adolescent sport and to draw conclusions on the strength of the evidence. A literature search in seven databases (Medline, SportDiscus, EMBASE, CINAHL, PEDro, Cochrane Review and DARE) was carried out using four keywords: adolescent, sport, injury and prevention (expanded to capture any relevant literature). Assessment of 154 papers found 12 studies eligible for inclusion. It can be concluded that injury prevention strategies that focus on preseason conditioning, functional training, education, balance and sport‐specific skills, which should be continued throughout the sporting season, are effective. The evidence for the effectiveness of protective equipment in injury prevention is inconclusive and requires further assessment. PMID:17496070

As engaging men in gender-based violence prevention efforts becomes an increasingly institutionalised component of gender equity work globally, clarity is needed about the strategies that best initiate male-identified individuals' involvement in these efforts. The purpose of this study was to examine the perceived relevance and effectiveness of men's engagement strategies from the perspective of men around the world who have organised or attended gender-based violence prevention events. Participants responded to an online survey (available in English, French and Spanish) and rated the effectiveness of 15 discrete engagement strategies derived from earlier qualitative work. Participants also provided suggestions regarding strategies in open-ended comments. Listed strategies cut across the social ecological spectrum and represented both venues in which to reach men, and the content of violence prevention messaging. Results suggest that all strategies, on average, were perceived as effective across regions of the world, with strategies that tailor messaging to topics of particular concern to men (such as fatherhood and healthy relationships) rated most highly. Open-ended comments also surfaced tensions, particularly related to the role of a gender analysis in initial men's engagement efforts. Findings suggest the promise of cross-regional adaptation and information sharing regarding successful approaches to initiating men's anti-violence involvement.

Objective One promising opportunity for advancing sexual violence (SV) research and identifying new avenues for prevention involves examining other forms of violence that may share risk factors with SV. Youth violence (YV) is ideal for consideration given evidence of overlap in SV and YV risk factors, a large set of established YV risk factors across the social ecology, and the number of evidence-based YV prevention strategies available. The current paper identifies shared and unique risk factors for SV and YV and highlights evidence-based YV prevention strategies that impact these shared risk factors. Conclusions Researchers and program developers should consider adapting and evaluating evidence-based YV prevention strategies to prevent SV. Modifying these programs to address SV’s unique risk factors may maximize their potential effectiveness. In addition, expanding SV research at the outer levels of the social ecology is critical to developing community-level prevention strategies. The YV literature suggests several potential risk factors at these levels in need of research for SV, including school connectedness, social disorganization, and availability of alcohol and drugs. Using the YV literature as a starting point for expanding SV research leverages prior investments in YV research, may help identify new SV prevention strategies at a limited cost, and moves the field more quickly toward implementation of cost-effective, multidomain violence prevention strategies in communities.

Patients who undergo prolonged surgical procedures are at risk of developing pressure ulcers. Recent systematic reviews suggest that pressure redistribution overlays on operating tables significantly decrease the associated risk. Little is known about the cost effectiveness of using these overlays in a prevention program for surgical patients. Using a Markov cohort model, we evaluated the cost effectiveness of an intraoperative prevention strategy with operating table overlays made of dry, viscoelastic polymer from the perspective of a health care payer over a 1-year period. We simulated patients undergoing scheduled surgical procedures lasting ≥90 min in the supine or lithotomy position. Compared with the current practice of using standard mattresses on operating tables, the intraoperative prevention strategy decreased the estimated intraoperative incidence of pressure ulcers by 0.51%, corresponding to a number-needed-to-treat of 196 patients. The average cost of using the operating table overlay was $1.66 per patient. Compared with current practice, this intraoperative prevention strategy would increase slightly the quality-adjusted life days of patients and by decreasing the incidence of pressure ulcers, this strategy would decrease both hospital and home care costs for treating fewer pressure ulcers originated intraoperatively. The cost savings was $46 per patient, which ranged from $13 to $116 by different surgical populations. Intraoperative prevention was 99% likely to be more cost effective than the current practice. In patients who undergo scheduled surgical procedures lasting ≥90 min, this intraoperative prevention strategy could improve patients' health and save hospital costs. The clinical and economic evidence support the implementation of this prevention strategy in settings where it has yet to become current practice. Copyright © 2011 Mosby, Inc. All rights reserved.
Cost-effectiveness of prevention strategies for American tegumentary leishmaniasis in Argentina.

2013-12-01
The aim of this study was to estimate the cost-effectiveness of reducing tegumentary leishmaniasis transmission using insecticide-impregnated clothing and curtains, and implementing training programs for early diagnosis. A societal perspective was adopted, with outcomes assessed in terms of costs per disability adjusted life years (DALY). Simulation was structured as a Markov model and costs were expressed in American dollars (US$). The incremental cost-effectiveness ratio of each strategy was calculated. One-way and multivariate sensitivity analyses were performed. The incremental cost-effectiveness ratio for early diagnosis strategy was estimated at US$ 156.46 per DALY averted, while that of prevention of transmission with insecticide-impregnated curtains and clothing was US$ 13,155.52 per DALY averted. Both strategies were more sensitive to the natural incidence of leishmaniasis, to the effectiveness of mucocutaneous leishmaniasis treatment and to the cost of each strategy. Prevention of vectorial transmission and early diagnosis have proved to be cost-effective measures.

HIV preexposure prophylaxis (PrEP) is an effective tool in preventing HIV infection among high-risk men who have sex with men (MSM). It is unknown how effective PrEP is in the context of other implemented HIV prevention strategies, including condom use, seroadaption, and treatment as prevention (TasP). We evaluate the impact of increasing uptake of PrEP in conjunction with established prevention strategies on HIV incidence in a high-risk population of MSM through simulation. Agent-based simulation models representing the sexual behavior of high-risk, urban MSM in the United States over the period of 1 year were used to evaluate the effect of PrEP on HIV infection rates. Simulations included data for 10,000 MSM and compared increasing rates of PrEP uptake under 8 prevention paradigms: no additional strategies, TasP, condom use, seroadaptive behavior, and combinations thereof. We observed a mean of 103.2 infections per 10,000 MSM in the absence of any prevention method. PrEP uptake at 25% without any additional prevention strategies prevented 30.7% of infections. In the absence of PrEP, TasP, condom use, and seroadaptive behavior independently prevented 27.1%, 48.8%, and 37.7% of infections, respectively, and together prevented 72.2%. The addition of PrEP to the 3 aforementioned prevention methods, at 25% uptake, prevented an additional 5.0% of infections. To achieve a 25% reduction in HIV infections by 2020, HIV prevention efforts should focus on significantly scaling up access to PrEP in addition to HIV testing, access to antiretroviral therapy, and promoting condom use.

Suicide is recognized as a global phenomenon and many countries now have national suicide prevention strategies. International guidance on suicide prevention and accepted epidemiological and treatment-based research underpins healthcare policy relating to suicide reduction. There has been an established comprehensive strategy in England since 2002. However, the rate of suicide continues to be a concern and nurses hold a key role in the implementation of national, regional and local policy into practice. The aim of this paper is to consider the current implications of the national suicide prevention strategy in England for nursing. This discussion paper draws upon both empirical evidence-based literature, governmental guidance and policy-related documentation. The national suicide prevention strategy for England currently continues to have a multifaceted impact on the nursing profession. This ranges from clinical practice issues such as risk assessment through to broader public health responsibilities. If nurses and allied health professionals are to be effective in their role within suicide prevention, they will need to be supported in building awareness of the wider context of the national policy. In particular, this will mean working effectively and collaboratively with the voluntary sector, service users and other non-medical agencies.
Suicide prevention via the Internet: a descriptive review.
Jacob, Nina; Scourfield, Jonathan; Evans, Rhiannon
2014-01-01
While concerns abound regarding the impact of the Internet on suicidal behaviors, its role as a medium for suicide prevention remains underexplored. The study examines what is currently known about the operation and effectiveness of Internet programs for suicide and self-harm prevention that are run by professionals. Systematic searches of scholarly databases and suicide-related academic journals yielded 15 studies that presented online prevention strategies. No professional programs with a sole focus on nonsuicidal self-harm were identified, thus all studies reviewed focused on suicide prevention. Studies were predominantly descriptive and summarized the nature of the strategy and the target audience. There was no formal evaluation of program effectiveness in preventing suicide. Studies either presented strategies that supported individuals at risk of suicide (n = 8), supported professionals working with those at risk (n = 6), or attempted to improve website quality (n = 1). Although the Internet increasingly serves as an important medium for suicidal individuals, and there is concern about websites that both promote and encourage suicidal activity, there is lack of published evidence about online prevention strategies. More attention is needed in the development and evaluation of such preventative approaches.
Women's perspectives on falls and fall prevention during pregnancy.
Brewin, Dorothy; Naninni, Angela
2014-01-01
Falls are the leading cause of unintentional injury in women. During pregnancy, even a minor fall can result in adverse consequences. Evidence to inform effective and developmentally appropriate pregnancy fall prevention programs is lacking. Early research on pregnancy fall prevention suggests that exercise may reduce falls. However, acceptability and effectiveness of pregnancy fall prevention programs are untested. To better understand postpartum women's perspective and preferences on fall prevention strategies during pregnancy to formulate an intervention. Focus groups and individual interviews were conducted with 31 postpartum women using descriptive qualitative methodology. Discussion of falls during pregnancy and fall prevention strategies was guided by a focus group protocol and enhanced by 1- to 3-minute videos on proposed interventions. Focus groups were audio recorded, transcribed, and analyzed using NVivo 10 software. Emerging themes were environmental circumstances and physical changes of pregnancy leading to a fall, prevention strategies, barriers, safety concerns, and marketing a fall prevention program. Wet surfaces and inappropriate footwear commonly contributed to falls. Women preferred direct provider counseling and programs including yoga and Pilates. Fall prevention strategies tailored to pregnant women are needed. Perspectives of postpartum women support fall prevention through provider counseling and individual or supervised exercise programs.

Infectious disease surveillance have played an important role in the national diseases prevention and control strategies. In line with the reporting system, infectious disease surveillance has been greatly improved and played pivotal role in preventing epidemics since 1949 in China. To date, surveillance remains an effective approach to infectious disease control and prevention because of the global serious situation. In this column "infectious disease surveillance" , we have involved articles as systematic analysis of surveillance data and solid evidence related to the development of strategies and measures for infectious diseases control and prevention.

Clinical trials provide evidence of the high effectiveness of Helicobacter pylori eradication for preventing recurrent ulcer-related gastrointestinal hemorrhage. The best strategy for curing the infection in this setting is, however, still under debate. To evaluate four different strategies for prevention of rebleeding in patients with peptic ulcer hemorrhage: 1) test for H. pylori and treatment, if positive; 2) proton pump inhibitor maintenance; 3) no preventive treatment; 4) empirical H. pylori eradication immediately after bleeding. A decision analysis model was used, with a time horizon of 2 years and a third-party payer perspective. Costs were estimated for two different settings: a low-cost-for-care area (Spain) and a high-cost area (USA). Main outcome measure was incremental cost-effectiveness ratio for each upper gastrointestinal hemorrhage avoided. Empirical H. pylori eradication was the dominant strategy: its estimated rate of recurrent bleeding was lower (6.1%) than those of strategies 1 (7.4%), 2 (11.1%), and 3 (18.4%) and it was the least expensive strategy. The results remained stable when variables were changed inside a wide range of plausible values. Sensitivity analysis also showed that the prevalence of H. pylori in bleeding ulcer was the variable that most influenced the results: when it was below 45% in Spain or below 51% in the United States, empirical eradication was not a dominant strategy although it remained cost-effective. In patients with bleeding peptic ulcer, empirical treatment of H. pylori infection immediately after feeding is restarted is the most cost-effective strategy for preventing recurrent hemorrhage.

Sport and recreational activities are the leading cause of injury in youth, yet there is increasing evidence that many sport-related injuries are preventable. For injury prevention strategies to be effective, individuals must understand, adopt and adhere to the recommended prevention strategy or programme. Despite the recognized importance of a behavioural approach, the inclusion of behavioural change strategies in sport injury prevention has been historically neglected. The purpose of this commentary is to outline the rationale for the inclusion and application of behavioural science in reducing the burden of injury by increasing adherence to proven prevention strategies. In an effort to provide an illustrative example of a behavioural change approach, the authors suggest a specific plan for the implementation of a neuromuscular training strategy to reduce the risk of lower limb injury in youth sport. Given the paucity of evidence in the sport injury prevention setting, and the lack of application of theoretical frameworks to predicting adoption and adherence to injury preventive exercise recommendations in youth sport, data from the related physical activity promotion domain is utilized to describe how sound, theory-based injury prevention exercise interventions in youth may be developed. While the question of how to facilitate behavioural change and optimize adherence to preventive exercise recommendations remains an ongoing challenge, the authors detail several strategies based on two prominent behavioural theories to aid the reader in conceptualizing, designing and implementing effective interventions. Despite the minimal application of behavioural theory within the field of sport injury prevention in youth, behavioural science has the potential to make a significant impact on the understanding and prevention of youth sport injury. Appropriate evaluation of adherence and maintenance components based on models of behavioural change should be a critical component of future injury prevention research and practice.

In an era of antiviral treatment, reexamination of the cost-effectiveness of strategies to prevent perinatal hepatitis B virus (HBV) transmission in the United States is needed. We used a decision tree and Markov model to estimate the cost-effectiveness of the current U.S. strategy and two alternatives: (1) Universal hepatitis B vaccination (HepB) strategy: No pregnant women are screened for hepatitis B surface antigen (HBsAg). All infants receive HepB before hospital discharge; no infants receive hepatitis B immunoglobulin (HBIG). (2) Current strategy: All pregnant women are screened for HBsAg. Infants of HBsAg-positive women receive HepB and HBIG ≤12 hours of birth. All other infants receive HepB before hospital discharge. (3) Antiviral prophylaxis strategy: All pregnant women are screened for HBsAg. HBsAg-positive women have HBV-DNA load measured. Antiviral prophylaxis is offered for 4 months starting in the third trimester to women with DNA load ≥10(6) copies/mL. HepB and HBIG are administered at birth to infants of HBsAg-positive women, and HepB is administered before hospital discharge to infants of HBsAg-negative women. Effects were measured in quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICER). Compared to the universal HepB strategy, the current strategy prevented 1,006 chronic HBV infections and saved 13,600 QALYs (ICER: $6,957/QALY saved). Antiviral prophylaxis dominated the current strategy, preventing an additional 489 chronic infections, and saving 800 QALYs and $2.8 million. The results remained robust over a wide range of assumptions. The current U.S. strategy for preventing perinatal HBV remains cost-effective compared to the universal HepB strategy. An antiviral prophylaxis strategy was cost saving compared to the current strategy and should be considered to continue to decrease the burden of perinatal hepatitis B in the United States. Published 2015. This article is a U.S. Government work and is in the public domain in the USA.

This article reviews 35 drug abuse prevention program evaluations employing drug-specific outcome measures. Many of these evaluations assessed the effects of "new generation" prevention strategies: affective, peer-oriented, and multidimensional approaches. Only 14 studies evaluated purely informational programs. Evaluations were analyzed to ascertain (1) characteristics of the programs under study, (2) characteristics of the research designs, and (3) patterns among findings. This review provides some evidence that the newer prevention strategies may produce more positive and fewer negative outcomes than did older drug information approaches. Over 70% of the programs using the newer strategies produced some positive effects; only 29% showed negative effects. In contrast, 46% of informational programs showed positive effects; 46% showed negative effects. These findings must be approached with great caution, since the research was frequently scientifically inadequate, and since rigor of research was negatively correlated with intensity and duration of program services.

Chronic pain is the leading cause of disability in the United States. The transition from acute to persistent pain is thought to arise from maladaptive neuroplastic mechanisms involving three intertwined processes, peripheral sensitization, central sensitization, and descending modulation. Strategies aimed at preventing persistent pain may target such processes. Models for studying preventive strategies include persistent post-surgical pain (PPP), persistent post-trauma pain (PTP) and post-herpetic neuralgia (PHN). Such entities allow a more defined acute onset of tissue injury after which study of the long-term effects is more easily examined. In this review, we examine the pathophysiology, epidemiology, risk factors, and treatment strategies for the prevention of chronic pain using these models. Both pharmacological and interventional approaches are described, as well as a discussion of preventive strategies on the horizon. PMID:22102847

Patients in the ICU are at the greatest risk of contracting healthcare-associated infections like methicillin-resistant Staphylococcus aureus. This study calculates the cost-effectiveness of methicillin-resistant S aureus prevention strategies and recommends specific strategies based on screening test implementation. A cost-effectiveness analysis using a Markov model from the hospital perspective was conducted to determine if the implementation costs of methicillin-resistant S aureus prevention strategies are justified by associated reductions in methicillin-resistant S aureus infections and improvements in quality-adjusted life years. Univariate and probabilistic sensitivity analyses determined the influence of input variation on the cost-effectiveness. ICU. Hypothetical cohort of adults admitted to the ICU. Three prevention strategies were evaluated, including universal decolonization, targeted decolonization, and screening and isolation. Because prevention strategies have a screening component, the screening test in the model was varied to reflect commonly used screening test categories, including conventional culture, chromogenic agar, and polymerase chain reaction. Universal and targeted decolonization are less costly and more effective than screening and isolation. This is consistent for all screening tests. When compared with targeted decolonization, universal decolonization is cost-saving to cost-effective, with maximum cost savings occurring when a hospital uses more expensive screening tests like polymerase chain reaction. Results were robust to sensitivity analyses. As compared with screening and isolation, the current standard practice in ICUs, targeted decolonization, and universal decolonization are less costly and more effective. This supports updating the standard practice to a decolonization approach.

To identify the optimal strategy for gastric cancer (GC) prevention by evaluating the cost-effectiveness of esophagogastroduodenoscopy (EGD)-based preventive strategies. We conducted a model-based cost-effectiveness analysis. Adopting a healthcare payer's perspective, Markov models simulated the clinical experience of the target population (Singaporean Chinese 50-69 years old) undergoing endoscopic screening, endoscopic surveillance and usual care of do-nothing. The screening strategy examined the cohort every alternate year whereas the surveillance strategy provided annual EGD only to people with precancerous lesions. For each strategy, discounted lifetime costs ($) and quality adjusted life years (QALY) were estimated and compared to generate incremental cost-effectiveness ratio (ICER). Deterministic and probabilistic sensitivity analysis was conducted to identify influential parameters and quantify the impact of model uncertainties. Annual EGD surveillance with an ICER of $34 200/QALY was deemed cost-effective for GC prevention within the Singapore healthcare system. To inform implementation, the models identified six influential factors and their respective thresholds, namely discount rate (<4.20%), age of starting surveillance (>51.6 years), proportion of program cost in delivering endoscopy (<65%), cost of follow-up EGD (<$484), utility of stage 1 GC patients (>0.72) and odds ratio of GC for high-risk subjects (>3.93). The likelihood that surveillance is the most cost-effective strategy is 69.5% accounting for model uncertainties. Endoscopic surveillance of gastric premalignancies can be a cost-effective strategy for GC prevention. Its implementation requires careful assessment on factors influencing the actual cost-effectiveness. © 2016 John Wiley & Sons Australia, Ltd.

Recruitment of minorities to cancer prevention trials is difficult and costly. Early-phase cancer prevention trials have fewer resources to promote recruitment. Identifying cost-effective strategies that can replace or supplement traditional recruitment methods and improve minority accrual to small, early-phase cancer prevention trials are of critical importance. To compare the costs of accrual strategies used in a small breast cancer prevention trial and assess their impact on recruitment and minority accrual. A total of 1196 potential subjects with a known recruitment source contacted study coordinators about the SOY study, a breast cancer prevention trial. Recruitment strategies for this study included recruitment from within the Northwestern University network (internal strategy), advertisements placed on public transportation (Chicago Transit Authority (CTA)), health-related events, media (print/radio/television), and direct mail. Total recruitment strategy cost included the cost of study personnel and material costs calculated from itemized receipts. Incremental cost-effectiveness ratios (ICERs) were calculated to compare the relative cost-effectiveness of each recruitment strategy. If a strategy was more costly and less effective than its comparator, then that strategy was considered dominated. Scenarios that were not dominated were compared. The primary effectiveness measure was the number of consents. Separate ICERs were calculated using the number of minority consents as the effectiveness measure. The total cost of SOY study recruitment was US$164,585, which included the cost of materials (US$26,133) and personnel (US$138,452). The internal referral strategy was the largest source of trial contacts (748/1196; 63%), consents (107/150; 71%), and minority consents (17/34; 50%) and was the most expensive strategy (US$139,033). CTA ads generated the second largest number of trial contacts (326/1196; 27%), the most minority contacts (184/321; 57%), and 16 minority consents (16/34; 47%), at a total cost of US$15,562. The other three strategies yielded many fewer contacts and consents. The methods of health events, CTA ads, and the internal strategy showed some evidence of cost-effectiveness (ICER: US$581, US$717, and US$1524, respectively). The CTA strategy was the most cost-effective strategy for minority accrual (ICER: US$908). Recall bias may have limited the accuracy of estimated time spent on recruitment by study personnel. Also, costs spent specifically on minority accrual were unobtainable; results may not be generalizable to other settings; and cost-effectiveness data for the methods of media, health events, and direct mail should be interpreted with caution since these methods generated few consents. Public transportation ads have the potential to generate numerous minority contacts and consents at a reasonable cost within an urban setting. Combined with traditional methods of recruitment, this method can lead to timelier study completion and increased minority accrual. Future research should prospectively track recruitment and costs in order to better assess the cost-effectiveness of recruitment methods used to target minority populations.

Background The hazardous health effects of smoking and second hand smoke have been confirmed in numerous studies. For Germany, the mortality attributable to smoking is estimated at 110,000 to 140,000 deaths per year, associated with annual smoking-related costs of 17 to 21 billion euro. Because the majority of smokers initiate this habit early in life, behavioural preventive strategies usually tried to prevent the uptake of smoking among children and youths. Objectives The goal of this HTA is to summarise the current literature on behavioural strategies for smoking prevention and to evaluate their medical effectiveness/efficacy and cost-effectiveness as well as the ethical, social and legal implications of smoking prevention programs. In addition, this report aims to compare the effectiveness and efficacy of different intervention components and to evaluate the reliability of results in the German context. Methods Relevant publications were identified by means of a structured search of databases accessed through the German Institute of Medical Documentation and Information (DIMDI). In addition a manual search of identified reference lists was conducted. The present report includes German and English literature published between August 2001 and August 2006 targeting youths up to 18 years old. The methodological quality of included studies was assessed according to pre-defined quality criteria, based on the criteria of evidence-based medicine. Results Among 3,580 publications 37 medical studies met the inclusion criteria. Overall study quality was satisfactory but only half the studies reported smoking uptake as an outcome, while the remaining studies reported alternative outcome parameters. The follow-up duration varied between twelve and 120 months. Although overall effectiveness of prevention programs showed considerable heterogeneity, there was evidence for the long-term effectiveness of behavioural smoking prevention programs. However, the reduction in smoking rates was only moderate. Community and multisectorial interventions reported more conclusive evidence for reductions in smoking rates, while the evidence for school-based programs alone was inconclusive. Only one study from Germany fulfilled the methodological criteria and was included in this report. Three included economic studies focused on school-based interventions. Study results suggested, that the cost-effectiveness of school-based behavioural interventions is positive. Discussion Behavioural preventive strategies were effective to delay or decrease uptake of smoking behaviour among children and youth. The effect size, however, was only moderate. Similar to previous research, there was no conclusive evidence for the long-term effectiveness of school-based interventions, whereas community and multisectorial interventions provided more conclusive evidence. However, sustainability of intervention effects has to be regarded with caution. In addition, there is evidence that findings from international studies can be adapted to the German situation and that intervention effectiveness is comparable. The available evidence regarding the cost-effectiveness of school-based interventions is not sufficient to draw reliable conclusions. Conclusion Behavioural preventive strategies can be effective in the prevention of smoking among children and youths. It seems advisable, though, to incorporate community strategies in addition to school-based strategies in order to improve their effectiveness. Future research should, amongst others, attempt to investigate the effectiveness of specific intervention components and the cost-effectiveness in methodologically high-quality studies. PMID:21289916

Disseminating lower-limb injury-prevention exercise programs (LL-IPEPs) with strategies that effectively reach coaches across sporting environments is a way of preventing lower-limb injuries (LLIs) and ensuring safe and sustainable sport participation. The aim of this study was to explore community-Australian Football (community-AF) coaches’ perspectives on the strategies they believed would enhance the dissemination and scale-up of LL-IPEPs. Using a qualitative multiple case study design, semi-structured interviews with community-AF coaches in Victoria, Australia, were conducted. Overall, coaches believed a range of strategies were important including: coach education, policy drivers, overcoming potential problem areas, a ‘try before you buy approach’, presenting empirical evidence and guidelines for injury-prevention exercise programs (IPEPs), forming strategic collaboration and working in partnership, communication and social marketing, public meetings, development of a coach hotline, and targeted multi-focused approaches. A shift to a culture whereby evidence-based IPEP practices in community-AF will take time, and persistent commitment by all involved in the sport is important. This will support the creation of strategies that will enhance the dissemination and scale-up of LL-IPEPs across community sport environments. The focus of research needs to continue to identify effective, holistic and multi-level interventions to support coaches in preventing LLIs. This could lead to the determination of successful strategies such as behavioural regulation strategies and emotional coping resources to implement LL-IPEPs into didactic curricula and practice. Producing changes in practice will require attention to which strategies are a priority and the most effective. PMID:29462913

The aim of this study was to evaluate the cost-effectiveness of a multifaceted implementation strategy for the prevention of hand eczema in comparison with a control group among healthcare workers. A total of 48 departments (n=1,649) were randomly allocated to the implementation strategy or the control group. Data on hand eczema and costs were collected at baseline and every 3 months. Cost-effectiveness analyses were performed using linear multilevel analyses. The probability of the implementation strategy being cost-effective gradually increased with an increasing willingness-to-pay, to 0.84 at a ceiling ratio of €590,000 per person with hand eczema prevented (societal perspective). The implementation strategy appeared to be not cost-effective in comparison with the control group (societal perspective), nor was it cost-beneficial to the employer. However, this study had some methodological problems which should be taken into account when interpreting the results.
The influence of cognitive load on transfer with error prevention training methods: a meta-analysis.

The objective was to conduct research synthesis for the U.S.Army on the effectiveness of two error prevention training strategies (training wheels and scaffolding) on the transfer of training. Motivated as part of an ongoing program of research on training effectiveness, the current work presents some of the program's research into the effects on transfer of error prevention strategies during training from a cognitive load perspective. Based on cognitive load theory, two training strategies were hypothesized to reduce intrinsic load by supporting learners early in acquisition during schema development. A transfer ratio and Hedges' g were used in the two meta-analyses conducted on transfer studies employing the two training strategies. Moderators relevant to cognitive load theory and specific to the implemented strategies were examined.The transfer ratio was the ratio of treatment transfer performance to control transfer. Hedges' g was used in comparing treatment and control group standardized mean differences. Both effect sizes were analyzed with versions of sample weighted fixed effect models. Analysis of the training wheels strategy suggests a transfer benefit. The observed benefit was strongest when the training wheels were a worked example coupled with a principle-based prompt. Analysis of the scaffolding data also suggests a transfer benefit for the strategy. Both training wheels and scaffolding demonstrated positive transfer as training strategies.As error prevention techniques, both support the intrinsic load--reducing implications of cognitive load theory. The findings are applicable to the development of instructional design guidelines in professional skill-based organizations such as the military.

Adequate implementation of work-related stress management interventions can reduce or prevent work-related stress and sick leave in organizations. We developed a multifaceted integral stress-prevention strategy for organizations from several sectors that includes a digital platform and collaborative learning network. The digital platform contains a stepwise protocol to implement work-related stress-management interventions. It includes stress screeners, interventions and intervention providers to facilitate access to and the selection of matching work-related stress-management interventions. The collaborative learning network, including stakeholders from various organizations, plans meetings focussing on an exchange of experiences and good practices among organizations for the implementation of stress prevention measures. This paper describes the design of an integral stress-prevention strategy, Stress Prevention@Work, and the protocol for the evaluation of: 1) the effects of the strategy on perceived stress and work-related outcomes, and 2) the barriers and facilitators for implementation of the strategy. The effectiveness of Stress Prevention@Work will be evaluated in a cluster controlled trial, in a large healthcare organization in the Netherlands, at six and 12 months. An independent researcher will match teams on working conditions and size and allocate the teams to the intervention or control group. Teams in the intervention group will be offered Stress Prevention@Work. For each intervention team, one employee is responsible for applying the strategy within his/her team using the digital platform and visiting the collaborative learning network. Using a waiting list design, the control group will be given access to the strategy after 12 months. The primary outcome is the employees' perceived stress measured by the stress subscale of the Depression, Anxiety, and Stress Scale (DASS-21). Secondary outcome measures are job demands, job resources and the number of preventive stress measures implemented at the team level. Alongside the trial, a process evaluation, including barriers and facilitators of the implementation of Stress Prevention@Work, will be conducted in one healthcare organisation. If Stress Prevention@Work is found to be effective in one healthcare organisation, further implementation on a broader scale might lead to increased productivity and decreased stress and sick leave in other organizations. Results are expected in 2018. NTR5527 . Registered 7 Dec 2015.

The project goal was to compare the effectiveness of strategies to prevent and de-escalate aggressive behaviors among psychiatric patients in acute care settings, including interventions for reducing use of seclusion and restraint. Relevant databases were systematically reviewed for comparative studies of violence prevention and de-escalation strategies involving adult psychiatric patients in acute care settings. Studies (trials and cohort studies) were required to report on aggression or seclusion or restraint outcomes. Both risk of bias, an indicator of quality of individual studies, and strength of evidence (SOE) for each outcome were independently assessed by two study personnel. Seventeen primary studies met inclusion criteria. Evidence was limited for benefits and harms; information about characteristics that might modify the interventions' effectiveness, such as race or ethnicity, was especially limited. All but one study had a medium or high risk of bias and thus presented worrisome limitations. For prevention, risk assessment reduced both aggression and use of seclusion and restraint (low SOE), and multimodal interventions reduced the use of seclusion and restraint (low SOE). SOE for all other interventions, whether aimed at preventing or de-escalating aggression, and for modifying characteristics was insufficient. Available evidence about strategies for preventing and de-escalating aggressive behavior among psychiatric patients is very limited. Two preventive strategies, risk assessment and multimodal interventions consistent with the Six Core Strategies principles, may effectively lower aggressive behavior and use of seclusion and restraint, but more research is needed on how best to prevent and de-escalate aggressive behavior in acute care settings.

Dengue is currently the highest and rapidly spreading vector-borne viral disease, which can lead to mortality in its severe form. The globally endemic dengue poses as a public health and economic challenge that has been attempted to suppress though application of various prevention and control techniques. Therefore, broad spectrum techniques, that are efficient, cost-effective, and environmentally sustainable, are proposed and practiced in dengue-endemic regions. The development of vaccines and immunotherapies have introduced a new dimension for effective dengue control and prevention. Thus, the present study focuses on the preventive and control strategies that are currently employed to counter dengue. While traditional control strategies bring temporary sustainability alone, implementation of novel biotechnological interventions, such as sterile insect technique, paratransgenesis, and production of genetically modified vectors, has improved the efficacy of the traditional strategies. Although a large-scale vector control strategy can be limited, innovative vaccine candidates have provided evidence for promising dengue prevention measures. The use of tetravalent dengue vaccine (CYD-TDV) has been the most effective so far in treating dengue infections. Nonetheless, challenges and limitation hinder the progress of developing integrated intervention methods and vaccines; while the improvement in the latest techniques and vaccine formulation continues, one can hope for a future without the threat of dengue virus.

Dengue is currently the highest and rapidly spreading vector-borne viral disease, which can lead to mortality in its severe form. The globally endemic dengue poses as a public health and economic challenge that has been attempted to suppress though application of various prevention and control techniques. Therefore, broad spectrum techniques, that are efficient, cost-effective, and environmentally sustainable, are proposed and practiced in dengue-endemic regions. The development of vaccines and immunotherapies have introduced a new dimension for effective dengue control and prevention. Thus, the present study focuses on the preventive and control strategies that are currently employed to counter dengue. While traditional control strategies bring temporary sustainability alone, implementation of novel biotechnological interventions, such as sterile insect technique, paratransgenesis, and production of genetically modified vectors, has improved the efficacy of the traditional strategies. Although a large-scale vector control strategy can be limited, innovative vaccine candidates have provided evidence for promising dengue prevention measures. The use of tetravalent dengue vaccine (CYD-TDV) has been the most effective so far in treating dengue infections. Nonetheless, challenges and limitation hinder the progress of developing integrated intervention methods and vaccines; while the improvement in the latest techniques and vaccine formulation continues, one can hope for a future without the threat of dengue virus.

Pressure ulcers are associated with substantial health burden, but could be preventable. Hospital-acquired pressure ulcers (HAPUs) prevention has become a priority for all healthcare settings, as it is considered a sign of quality of care providing. Intensive care unit (ICU) patients are at higher risk for HAPUs development. Despite the availability of published prevention strategies, there is a little evidence about which strategies can be safely integrated into routine standard care and have an impact on HAPUs prevention. The aim was to synthesize the best available evidence regarding the effectiveness of single strategies designed to reduce the incidence and prevalence of HAPUs development in ICUs. The search strategy was designed to retrieve studies published in English across CINAHL, Medline, Cochrane Central Register of Controlled Trials, Embase, Scopus, and Mednar between 2000 and 2015. All adult ICU participants were aged 18 years or over. This review included randomized controlled trials, quasi-experimental and comparative studies. The studies that were selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical-appraisal instruments. The review included 25 studies, and the meta-analysis revealed a statistically significant effect of a silicon foam dressing strategy in reducing HAPUs incidence (effect size = 4.62; 95% CI: 0.05-0.29; p < .00001, effect size = 4.50; 95% CI: 0.05-0.31; p = .00001, respectively) in critically ill patients. Evidence of the effectiveness of nutrition, skin-care regimen, positioning and repositioning schedule, support surfaces, and the role of education in prevention of HAPUs development in the ICU was limited, which precludes strong conclusions. The review provides an evidence-based guide to future priorities for clinical practice. In particular, a silicone foam dressing has positive impact in reducing sacrum and heel HAPUs incidence in the ICU. © 2016 Sigma Theta Tau International.

Introduction Mechanically ventilated critically ill patients frequently develop ventilator-associated pneumonia (VAP), a life-threatening complication. Proposed preventive measures against VAP include, but are not restricted to, selective decontamination of the digestive tract (SDD), selective oropharyngeal decontamination (SOD) and the use of probiotics. Probiotics are live bacteria that could have beneficial effects on the host by altering gastrointestinal flora. Similar to SDD and SOD, a prescription of probiotics aims at the prevention of secondary colonization of the upper and/or lower digestive tract. Methods We performed a literature review to describe the differences and similarities between SDD/SOD and probiotic preventive strategies, focusing on (a) efficacy, (b) risks, and (c) the routing of these strategies. Results Reductions in the incidence of VAP have been achieved with SDD and SOD. Two large randomized controlled trials even showed reduced mortality with these preventive strategies. Randomized controlled trials of probiotic strategies also showed a reduction of the incidence of VAP, but trials were too small to draw firm conclusions. Preventive strategies with antibiotics and probiotics may be limited due to the risk of emerging resistance to the locally applied antibiotics and the risk of probiotic-related infections, respectively. The majority of trials of SDD and SOD did not exhaustively address the issue of emerging resistance. Likewise, trials of probiotic strategies did not adequately address the risk of colonization with probiotics and probiotic-related infection. In studies of SDD and SOD the preventive strategy aimed at decontamination of the oral cavity, throat, stomach and intestines, and the oral cavity and throat, respectively. In the vast majority of studies of probiotic therapy the preventive strategy aimed at decontamination of the stomach and intestines. Conclusions Prophylactic use of antibiotics in critically ill patients is effective in reducing the incidence of VAP. Probiotic strategies deserve consideration in future well-powered trials. Future studies are needed to determine if preventive antibiotic and probiotic strategies are safe with regard to development of antibiotic resistance and probiotic infections. It should be determined whether the efficacy of probiotics improves when these agents are provided to the mouth and the intestines simultaneously. PMID:21232110
Injury prevention in child and adolescent sport: whose responsibility is it?
Emery, Carolyn A; Hagel, Brent; Morrongiello, Barbara A
2006-11-01
Sport and recreational injuries are a leading cause of morbidity in youth. There is a significant body of literature on risk factors for sport-related injuries and a growing body of research supporting the effectiveness of sport-specific prevention strategies in youth. Given the predictability and preventability of injuries in youth sport, the purpose of this article is to develop a model that considers societal responsibility for injury prevention in youth sport, and to discuss the evidence that supports this model. Previously published papers have provided a basis for expert opinion to discuss an approach to examining the shared societal responsibility for implementing countermeasures to reduce the risk of injury to youth during sports. Based on a historical perspective, broad conceptual framework, and specific evidence for prevention strategies in youth sport, the authors have developed and supported a theoretical model that defines a responsibility hierarchy in preventing injuries in youth sport. An argument has been made for a hierarchy of responsibility, with the lowest level of responsibility assigned to the child, and the highest level to those organizations or groups with the potential to effect the most change. The justification for this approach has been discussed in the context of the desirability of passive prevention strategies, the limited evidence for the effectiveness of strategies relying solely on behavior change in children and parents, and the level of perceptual and cognitive development in children that inadequately prepares them to take primary responsibility for their own safety in sport. The development of effective programs to reduce the burden of sport injury among youth necessitates a scientific approach, the identification of key risk factors for injury, a thorough examination of how factors interact to affect risk, and the identification of potential barriers to the effectiveness of injury-prevention programs.

This study sought to determine if knowledge regarding the risk for knee injuries and the potential for their prevention is being translated to female adolescent soccer players (13-18 years), their parents, and coaches. Eligible participants in the 2007 indoor soccer season were surveyed to determine their knowledge of the risk for and the potential to prevent knee injuries, and their knowledge of effective prevention strategies, if they felt that injury prevention was possible. Team selection was stratified to be representative of both competitive and recreational level play and age group distributions within the selected soccer association. Of the study subjects, 773/1396 (55.4%) responded to the survey: 408 (53%) players, 292 (38%) parents, and 73 (9%) coaches. Most respondents (538 [71%]) were aware of the risk for knee injury. Coaches and parents were more likely than players to view knee injuries as preventable; however, appropriate prevention strategies were often not identified. Four hundred eighty-four (63.8%) respondents reported that they had never received information on knee injuries. Substantial knowledge gaps regarding knee injury prevention and effective preventative strategies were identified. Given the predominance of knee injuries in female adolescent soccer players, there is an urgent need for knowledge translation of prevention strategies to decrease both incidence and long-term consequences of knee injuries. © 2011 John Wiley & Sons A/S.
Can we prevent OA? Epidemiology and public health insights and implications.
Runhaar, Jos; Zhang, Yuqing
2018-05-01
This narrative review discusses the potential of prevention of OA in different stages of the disease. The theoretical background for primary prevention (i.e. prevention of occurrence of definite structural or clinical OA in subjects free of the disease) and secondary prevention (i.e. prevention of progression of the disease in subjects with pre-clinical pathological changes to the joint) is provided and evidence for effective strategies is discussed. Since direct evidence for the prevention of OA development and progression is scarce, indirect evidence enhancing our current knowledge on the potential of OA prevention is additionally discussed. Also, implications of preventive strategies for study design and public health are considered. Prevention of OA has great potential, but as deliberated in the current review, there are still large gaps in our current knowledge and the implications of preventive strategies for the development and progression of OA require consideration.

Recurrent variceal hemorrhage is common following an initial bleed in patients with cirrhosis. The current standard of care for secondary prophylaxis is endoscopic band ligation (EBL). Combination of beta-blocker and nitrate therapy, guided by hepatic venous pressure gradient (HVPG) monitoring, is a novel alternative strategy. We sought to determine the cost-effectiveness of these competing strategies. Decision analysis with Markov modeling was used to calculate the cost-effectiveness of three competing strategies: (1) EBL; (2) beta-blocker and nitrate therapy without HVPG monitoring (HVPG-); and (3) beta-blocker and nitrate therapy with HVPG monitoring (HVPG+). Patients in the HVPG+ strategy who failed to achieve an HVPG decline from medical therapy were offered EBL. Cost estimates were from a third-party payer perspective. The main outcome measure was the cost per recurrent variceal hemorrhage prevented. Under base-case conditions, the HVPG+ strategy was the most effective yet most expensive approach, followed by EBL and HVPG-. Compared to the EBL strategy, the HVPG+ strategy cost an incremental 5,974 dollars per recurrent bleed prevented. In a population with 100% compliance with all therapies, the incremental cost of HVPG-versus EBL fell to 5,270 dollars per recurrent bleed prevented. The model results were sensitive to the cost of EBL, the cost of HVPG monitoring, and the probability of medical therapy producing an adequate HVPG decline. Compared to EBL for the secondary prophylaxis of variceal rebleeding, combination medical therapy guided by HVPG monitoring is more effective and only marginally more expensive.

OBJECTIVE To create a national policy model to evaluate the projected cost-effectiveness of multiple hospital-based strategies to prevent methicillin-resistant Staphylococcus aureus (MRSA) transmission and infection. DESIGN Cost-effectiveness analysis using a Markov microsimulation model that simulates the natural history of MRSA acquisition and infection. PATIENTS AND SETTING Hypothetical cohort of 10,000 adult patients admitted to a US intensive care unit. METHODS We compared 7 strategies to standard precautions using a hospital perspective: (1) active surveillance cultures; (2) active surveillance cultures plus selective decolonization; (3) universal contact precautions (UCP); (4) universal chlorhexidine gluconate baths; (5) universal decolonization; (6) UCP + chlorhexidine gluconate baths; and (7) UCP+decolonization. For each strategy, both efficacy and compliance were considered. Outcomes of interest were: (1) MRSA colonization averted; (2) MRSA infection averted; (3) incremental cost per colonization averted; (4) incremental cost per infection averted. RESULTS A total of 1989 cases of colonization and 544 MRSA invasive infections occurred under standard precautions per 10,000 patients. Universal decolonization was the least expensive strategy and was more effective compared with all strategies except UCP+decolonization and UCP+chlorhexidine gluconate. UCP+decolonization was more effective than universal decolonization but would cost $2469 per colonization averted and $9007 per infection averted. If MRSA colonization prevalence decreases from 12% to 5%, active surveillance cultures plus selective decolonization becomes the least expensive strategy. CONCLUSIONS Universal decolonization is cost-saving, preventing 44% of cases of MRSA colonization and 45% of cases of MRSA infection. Our model provides useful guidance for decision makers choosing between multiple available hospital-based strategies to prevent MRSA transmission.

Different intervention strategies can prevent type 2 diabetes (T2DM). Aim of the present systematic review and meta-analysis was to evaluate the effectiveness of different strategies. Studies were grouped into 15 different strategies: 1: diet plus physical activity; 2: physical activity; 3-6: anti-diabetic drugs [glitazones, metformin, beta-cell stimulating drugs (sulphanylureas, glinides), alfa-glucosidase inhibitors]; 7-8: cardiovascular drugs (ACE inhibitors, ARB, calcium antagonists); 9-14 [diets, lipid-affecting drugs (orlistat, bezafibrate), vitamins, micronutrients, estrogens, alcohol, coffee]; 15: bariatric surgery. Only controlled studies were included in the analysis, whether randomized, non-randomized, observational studies, whether primarily designed to assess incident cases of diabetes, or performed with other purposes, such as control of hypertension, of ischemic heart disease or prevention of cardiovascular events. Appropriate methodology [preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement] was used. Seventy-one studies (490 813 subjects), published as full papers, were analysed to identify predictors of new cases of T2DM, and were included in a meta-analysis (random-effects model) to study the effect of different strategies. Intervention effect (new cases of diabetes) was expressed as odds ratio (OR), with 95% confidence intervals (C.I.s). Publication bias was formally assessed. Body mass index was in the overweight range for 13 groups, obese or morbidly obese in lipid-affecting drugs and in bariatric surgery. Non-surgical strategies, except for beta-cell stimulating drugs, estrogens and vitamins, were able to prevent T2DM, with different effectiveness, from 0.37 (C.I. 0.26-0.52) to 0.85 (C.I. 0.77-0.93); the most effective strategy was bariatric surgery in morbidly obese subjects [0.16 (C.I. 0.11,0.24)]. At meta-regression analysis, age of subjects and amount of weight lost were associated with effectiveness of intervention. These data indicate that several strategies prevent T2DM, making it possible to make a choice for the individual subject. © 2014 John Wiley & Sons Ltd.

Due to concerns over Thai adolescent risky behaviors, effective prevention strategies are needed. Determining the role neighborhood context plays in program engagement and outcomes may inform these strategies. This study includes 170 mother-adolescent pairs (M = 13.44, SD = .52) in Bangkok, Thailand in a prevention program for adolescent substance use and sexual risk. Neighborhoods were related to engagement, which was critical to outcomes. Neighborhood disorganization was related to confidence in program effects and program completion. Completion was related to increased ATOD communication. Neighborhood cohesion was related to less program enjoyment, while neighborhood social control was related to more enjoyment. Enjoyment was related to increased ATOD communication and formation and monitoring of alcohol rules. Prevention strategies should focus on neighborhood contexts and enhancing engagement.

To offer an overview of sport-related concussion (SRC) prevention and education strategies in the context of the socioecological framework (SEF). Athletic trainers (ATs) will understand the many factors that interact to influence SRC prevention and the implications of these interactions for effective SRC education. Concussion is a complex injury that is challenging to identify and manage, particularly when athletes fail to disclose symptoms to their health care providers. Education is 1 strategy for increasing disclosure. However, limited information addresses how ATs can integrate the many factors that may influence the effectiveness of SRC education into their specific settings. Public health models provide an example through the SEF, which highlights the interplay among various levels of society and sport that can facilitate SRC prevention strategies, including education. For ATs to develop appropriate SRC prevention strategies, a framework for application is needed. A growing body of information concerning SRC prevention indicates that knowledge alone is insufficient to change concussion-related behaviors. The SEF allows this information to be considered at levels such as policy and societal, community, interpersonal (relationships), and intrapersonal (athlete). The use of such a framework will facilitate more comprehensive SRC prevention efforts that can be applied in all athletic training practice settings. Clinical Applications: Athletic trainers can use this information as they plan SRC prevention strategies in their specific settings. This approach will aid in addressing the layers of complexity that exist when developing a concussion-management policy and plan.

Response strategy is a key for preventing widespread corruption vulnerabilities in the public construction sector. Although several studies have been devoted to this area, the effectiveness of response strategies has seldom been evaluated in China. This study aims to fill this gap by investigating the effectiveness of response strategies for corruption vulnerabilities through a survey in the Chinese public construction sector. Survey data obtained from selected experts involved in the Chinese public construction sector were analyzed by factor analysis and partial least squares-structural equation modeling. Analysis results showed that four response strategies of leadership, rules and regulations, training, and sanctions, only achieved an acceptable level in preventing corruption vulnerabilities in the Chinese public construction sector. This study contributes to knowledge by improving the understanding of the effectiveness of response strategies for corruption vulnerabilities in the public construction sector of developing countries.

Only little is known about costs and effects (i.e., success) of dissemination strategies, although cost-effective dissemination strategies are crucial for the transfer of interventions into routine care. This study investigates the effects and cost-effectiveness of five school-based dissemination strategies for an Internet-based intervention for the prevention and early intervention of eating disorders. Three-hundred ninety-five schools were randomly assigned to one of five dissemination strategies. Strategies varied with respect to intensity from only sending advertisement materials and asking the school to distribute them among students to organizing presentations and workshops at schools. Effects were defined as the number of page visits, the number of screenings conducted, and the number of registrations to the Internet-based intervention. More expensive strategies proved to be more cost-effective. Cost per page visit ranged from 2.83€ (introductory presentation plus workshop) to 20.37€ (dissemination by student representatives/peers). Costs per screening ranged from 3.30€ (introductory presentation plus workshop) to 75.66€ (dissemination by student representatives/peers), and costs per registration ranged from 6.86€ (introductory presentation plus workshop) to 431.10€ (advertisement materials only). Dissemination of an Internet-based intervention for prevention and early intervention is challenging and expensive. More intense, expensive strategies with personal contact proved to be more cost-effective. The combination of an introductory presentation on eating disorders and a workshop in the high school was most effective and had the best cost-effectiveness ratio. The sole distribution of advertisement materials attracted hardly any participants to the Internet-based program.

Schools are often held responsible for preventing or addressing cyberbullying, yet little is known about school administrator perceptions of cyberbullying and the challenges they face in addressing this public health issue. The goal of this study is to examine school administrators' perceptions of the facilitators of cyberbullying and barriers to primary and secondary prevention strategies. Public school administrators ( N = 36) participated in in-depth interviews about bullying and discussed their experiences with cyberbullying and their perceptions of cyberbullying facilitators and barriers to prevention. Three main themes arose from the analysis: (1) cyberbullying as a major challenge; (2) facilitators of cyberbullying and barriers to preventive action, including parents and technology; and (3) prevention efforts, including unclear jurisdiction for action, primary versus secondary prevention efforts, and technology attributes that facilitate school response to bullying. Although administrators perceive cyberbullying as a major challenge facing their schools, they are often unsure about appropriate primary and secondary prevention efforts. Relationships with parents and police complicate response and prevention as schools attempt to navigate unclear jurisdiction. Additionally, technology presents a challenge to schools because it is seen as an enabler of cyberbullying, a facilitator of prevention, and a necessary part of education efforts. Lack of research on prevention strategies, parents' knowledge and attitudes, and confusion about responsibility for addressing cyberbullying are barriers to action. Findings suggest administrators could benefit from additional clarity on which strategies are most effective for primary prevention of cyberbullying, and that prevention strategies should proactively involve parents to promote effective collaboration with schools.

[Efficacy of mental health prevention and promotion strategies in higher education].
Martineau, Marc; Beauchamp, Guy; Marcotte, Diane
Recent studies inform of increases in reported mental health problems in higher education students worldwide, with suicide and homicide being the most dramatic outcomes. Improving first-hand intervention and implementing mental health prevention and promotion strategies in colleges and universities are amongst the most commonly mentioned means of addressing these concerns. While institutions increasingly favor mental health promotion, most programs have not been properly evaluated and most strategies cannot be replicated. The article analyses results obtained from literature reviews and meta-analysis focusing on mental health prevention and promotion strategies targeting college and university students. Mindfulness, cognitive-behavioral and relaxation strategies, as well as social ability training, appeared to be the most effective if they were practiced under supervision. The implementation of supervised mental health prevention strategies within a setting-based systematic and multifactorial promotion frame could significantly decrease mental health problems in higher education students.

There is growing enthusiasm for increasing coverage of antiretroviral treatment among HIV-infected people for the purposes of preventing ongoing transmission. Treatment as prevention will face a number of barriers when implemented in real world populations, which will likely lead to the effectiveness of this strategy being lower than proposed by optimistic modelling scenarios or ideal clinical trial settings. Some settings, as part of their prevention and treatment strategies, have already attained rates of HIV testing and use of antiretroviral therapy—with high levels of viral suppression—that many countries would aspire to as targets for a treatment-as-prevention strategy. This review examines a number of these “natural experiments”, namely, British Columbia, San Francisco, France, and Australia, to provide commentary on whether treatment as prevention has worked in real world populations. This review suggests that the population-level impact of this strategy is likely to be considerably less than as inferred from ideal conditions. PMID:22807656

Although China has paid more attention on the prevention and control of tuberculosis (TB) in schools, several unsolved questions in this field still threaten the progress of TB control. Therefore, there is an urgent need to develop a systematic and practical strategy for Chinese school TB prevention and control system. In this study, we aimed to assess the feasibility of a combined strategy named ESMPE (examination, screening, monitoring, prevention and education) that adhere to the basic principles of Chinese schools TB control strategy. The ESMPE strategy included five sections, namely TB screening during physical examination for the school freshmen entrances, screening of close contacts, monitoring of high-risk schools, preventive treatment and TB education. The effectiveness of ESMPE strategy was evaluated from 2011 to 2016. The original data were provided by the Dalian Tuberculosis Hospital. Descriptive analysis and nonparametric tests were used for comparing statistical differences of results between different years. The detection rate of active pulmonary TB in school freshmen was decreased from 2011 to 2016 (χ2 = 41.941, P = 6.0551E-8). 97.22% (17,043/17,530) of close contacts experienced close contacts screening, and the secondary attack rate (SAR) of TB in schools fell by 146.35/105 from 2011 to 2012, and finally reduced to 85.57/105 in 2016. There was a significant correlation between SAR of student TB and the rate of screened close contacts (r = -0.924, P = 0.009). TB incidence of five monitored schools had a substantial decline after receiving monitoring, and this declining trend continued in 2016. Due to the TB education and advanced screening methods, the mean of diagnostic delay time in students with TB was shortened (15.71 days), while still fewer latent TB infection students received preventive treatment (30.38%). The ESMPE strategy has shown a favorable effect on TB prevention and control in Dalian schools. More systematic evidence is needed on the effect of this strategy in reducing the incidence of TB in schools from other settings prior to its further scaling-up in China.

Cancer is a global health issue as a multi-factorial complex disease, and early detection and novel therapeutic strategies are required for more effective cancer management. With the development of systemic analytical -omics strategies, the therapeutic approach and study of the molecular mechanisms of carcinogenesis and cancer progression have moved from hypothesis-driven targeted investigations to data-driven untargeted investigations focusing on the integrated diagnosis, treatment, and prevention of cancer in individual patients. Predictive, preventive, and personalized medicine (PPPM) is a promising new approach to reduce the burden of cancer and facilitate more accurate prognosis, diagnosis, as well as effective treatment. Here we review the fundamentals of, and new developments in, -omics technologies, together with the key role of a variety of practical -omics strategies in PPPM for cancer treatment and diagnosis. In this review, a comprehensive and critical overview of the systematic strategy for predictive, preventive, and personalized medicine (PPPM) for cancer disease was described in a view of cancer prognostic prediction, diagnostics, and prevention as well as cancer therapy and drug responses. We have discussed multi-dimensional data obtained from various resources and integration of multisciplinary -omics strategies with computational method which could contribute the more effective PPPM for cancer. This review has provided the novel insights of the current applications of each and combined -omics technologies, which showed their powerful potential for the establishment of PPPM for cancer.

Healthcare workers have an increased risk of developing hand eczema. A multifaceted implementation strategy was developed to implement a guideline to prevent hand eczema among healthcare workers. To investigate the effects of the implementation strategy on self-reported hand eczema and preventive behaviour. A randomized controlled trial was performed. A total of 48 departments (n = 1649) were randomly allocated to the multifaceted implementation strategy or the control group. The strategy consisted of education, participatory working groups, and role models. Outcome measures were self-reported hand eczema and preventive behaviour. Data were collected at baseline, and 3, 6, 9 and 12 months of follow-up. Participants in the intervention group were significantly more likely to report hand eczema [odds ratio (OR) 1.45; 95% confidence interval (CI) 1.03-2.04], and they reported significantly less hand washing (B, - 0.38; 95%CI: - 0.48 to - 0.27), reported significantly more frequent use of a moisturizer (B, 0.30; 95%CI: 0.22-0.39) and were more likely to report wearing cotton undergloves (OR 6.33; 95%CI: 3.23-12.41) than participants in the control group 12 months after baseline. The strategy implemented can be used in practice, as it showed positive effects on preventive behaviour. More research is needed to investigate the unexpected effects on hand eczema. © 2014 The Authors. Contact Dermatitis published by John Wiley & Sons Ltd.
A Markov chain model for studying suicide dynamics: an illustration of the Rose theorem
2014-01-01
Background High-risk strategies would only have a modest effect on suicide prevention within a population. It is best to incorporate both high-risk and population-based strategies to prevent suicide. This study aims to compare the effectiveness of suicide prevention between high-risk and population-based strategies. Methods A Markov chain illness and death model is proposed to determine suicide dynamic in a population and examine its effectiveness for reducing the number of suicides by modifying certain parameters of the model. Assuming a population with replacement, the suicide risk of the population was estimated by determining the final state of the Markov model. Results The model shows that targeting the whole population for suicide prevention is more effective than reducing risk in the high-risk tail of the distribution of psychological distress (i.e. the mentally ill). Conclusions The results of this model reinforce the essence of the Rose theorem that lowering the suicidal risk in the population at large may be more effective than reducing the high risk in a small population.

2003-01-01
Musculoskeletal disorders in the workplace cause thousands of injuries and cost industry billions of dollars yearly. Work injury prevention programs have been developed and implemented as a means for cost containment. A variety of preventive strategies have been investigated in primary research. The purpose of this review article is to examine the effectiveness of back injury and pain prevention programs in the workplace. Nine studies published between 1995 and 2000 were reviewed and analyzed. Studies used primarily one of three types of preventive strategies: 1) back belts, 2) education and task modification, and 3) education and task modification with workstation redesign. The effectiveness of back belts to prevent back pain and injury remains inconclusive. Positive outcomes were associated with studies reporting high compliance that used job-specific and individualized/small group education and training approaches. Themes that arose following a critical review of primary research studies are discussed.

Specific intervention strategies ( i.e ., comfort positioning, nonnutritive sucking and sucrose analgesia, distraction) were identified, selected and introduced in three waves, using a Plan-Do-Study-Act framework. System-wide change was measured from baseline to post-intervention by: (1) percent of vaccination visits during which an evidence-based pain prevention strategy was reported as being used; and (2) caregiver satisfaction ratings following the visit. Additionally, self-reported staff and caregiver attitudes and beliefs about pain prevention were measured at baseline and 1-year post-intervention to assess for possible long-term cultural shifts. Significant improvements were noted post-intervention. Use of at least one pain prevention strategy was documented at 99% of patient visits and 94% of caregivers were satisfied or very satisfied with the pain prevention care received. Parents/caregivers reported greater satisfaction with the specific pain prevention strategy used [ t (143) = 2.50, P ≤ 0.05], as well as greater agreement that the pain prevention strategies used helped their children's pain [ t (180) = 2.17, P ≤ 0.05] and that they would be willing to use the same strategy again in the future [ t (179) = 3.26, P ≤ 0.001] as compared to baseline. Staff and caregivers also demonstrated a shift in attitudes from baseline to 1-year post-intervention. Specifically, staff reported greater agreement that the pain felt from vaccinations can result in harmful effects [2.47 vs 3.10; t (70) = -2.11, P ≤ 0.05], less agreement that pain from vaccinations is "just part of the process" [3.94 vs 3.23; t (70) = 2.61, P ≤ 0.05], and less agreement that parents expect their children to experience pain during vaccinations [4.81 vs 4.38; t (69) = 2.24, P ≤ 0.05]. Parents/caregivers reported more favorable attitudes about pain prevention strategies for vaccinations across a variety of areas, including safety, cost, time, and effectiveness, as well as less concern about the pain their children experience with vaccination [4.08 vs 3.26; t (557) = 6.38, P ≤ 0.001], less need for additional pain prevention strategies [3.33 vs 2.81; t (476) = 4.51, P ≤ 0.001], and greater agreement that their doctors' office currently offers pain prevention for vaccinations [3.40 vs 3.75; t (433) = -2.39, P ≤ 0.05]. Quality improvement methodology can be used to help close the gap in implementing pain prevention strategies during routine vaccination procedures for children.

To compare prenatal maternal hepatitis B virus (HBV) screening and infant vaccination strategies to inform policy on HBV prevention in Sub-Saharan Africa. A decision analytic model was created using previously published data to assess the ability of three intervention strategies to prevent HBV infection by age 10 years. Strategy 1 comprised of universal vaccination with a pentavalent vaccine (HBV, diphtheria, tetanus, pertussis, and Haemophilus influenzae) at age 6 weeks. Strategy 2 comprised of universal HBV vaccine at birth plus pentavalent vaccine. Strategy 3 comprised of maternal prenatal HBV screening and targeted HBV vaccine at birth for all exposed infants plus pentavalent vaccine. The reference strategy provided neither maternal screening nor infant vaccination. Rates of HBV infection and costs were compared. The reference strategy had an HBV infection rate of 2360 per 10 000 children. The HBV infection rate for strategy 1 was 813 per 10 000 children vaccinated (1547 cases prevented). Strategies 2 and 3 prevented an additional 384 cases and 362 cases, respectively. Inclusion of HBV vaccination at birth was the preferred approach at a willingness-to-pay threshold of US$150. Including a birth-dose HBV vaccine in the standard schedule was both cost-effective and prevented additional infections. © 2018 International Federation of Gynecology and Obstetrics.

Purpose: The present qualitative study explored adolescents’ perceptions regarding effective strategies to prevent adolescents from using tobacco products (TP). Apart from the commercial TPs, there has been emerging use of alternatives such as vapes, e-cigarettes and shisha. This unfortunate phenomenon continues despite the currently available preventive strategies. Thus, understanding of the perceptions of the current generation would be valuable to provide new insights. Methods: Purposive sampling was utilized to recruit 40 adolescents between the age of 15 and 16 years old attending public daily secondary schools. Eight focus group discussions were conducted among the TP users, ex-users and non-users. Data were analyzed using a thematic content analysis procedure with NVivo. Results: Among barriers with the currently available strategies were having teachers who smoke tobacco, addiction to nicotine and self-perceptions of being healthy. The content of any program should include knowledge on negative outcomes of using tobacco products and awareness of the legislation together with ways to overcome peer and family influence including improving self-efficacy and refusal skills. Strategies were suggested to be delivered using information technology which provides interactive learning and visual effects. Conclusions: Adolescents agreed that the content and delivery of tobacco use prevention strategies need to be revised to suit the current generation to ensure sustainability. PMID:28122443

Current approaches to prevention of contrast induced acute kidney injury.
Blandon, Jimena; Mukherjee, Debabrata
2011-10-01
Contrast-induced acute kidney injury is one of the leading causes of hospital-acquired acute kidney injury. Thus far, no strategies have been clearly shown to be effective in preventing contrast-induced acute kidney injury beyond thorough patient selection, meticulous hydration of the patient, and minimizing the amount of contrast used. Additional studies are needed to define the optimal means of hydration, role of commonly advocated prophylaxis strategies such as N-acetylcysteine and develop newer more novel effective therapies to prevent or minimize the risk of kidney injury.

Background Several approaches have been proposed for risk-stratification and primary prevention of coronary heart disease (CHD), but their comparative and cost-effectiveness is unknown. Methods We constructed a state-transition microsimulation model to compare multiple approaches to the primary prevention of CHD in a simulated cohort of men aged 45–75 and women 55–75. Risk-stratification strategies included the 2013 American College of Cardiology/American Heart Association (ACC/AHA) guidelines on the treatment of blood cholesterol, the Adult Treatment Panel (ATP) III guidelines, and approaches based on coronary artery calcium (CAC) scoring and C-reactive protein (CRP). Additionally we assessed a treat-all strategy in which all individuals were prescribed either moderate-dose or high-dose statins and all males received low-dose aspirin. Outcome measures included CHD events, costs, medication-related side effects, radiation-attributable cancers, and quality-adjusted-life-years (QALYs) over a 30-year timeframe. Results Treat-all with high-dose statins dominated all other strategies for both men and women, gaining 15.7 million QALYs, preventing 7.3 million myocardial infarctions, and saving over $238 billion, compared to the status quo, far outweighing its associated adverse events including bleeding, hepatitis, myopathy, and new-onset diabetes. ACC/AHA guidelines were more cost-effective than ATP III guidelines for both men and women despite placing 8.7 million more people on statins. For women at low CHD risk, treat-all with high-dose statins was more likely to cause a statin-related adverse event than to prevent a CHD event. Conclusions Despite leading to a greater proportion of the population placed on statin therapy, the ACC/AHA guidelines are more cost-effective than ATP III. Even so, at generic prices, treating all men and women with statins and all men with low-dose aspirin appears to be more cost-effective than all risk-stratification approaches for the primary prevention of CHD. Especially for low-CHD risk women, decisions on the appropriate primary prevention strategy should be based on shared decision making between patients and healthcare providers. PMID:26422204

Data on the cost effectiveness of hepatitis B virus (HBV) screening and vaccination strategies for prevention of vertical transmission of HBV in resource limited settings is sparse. A decision tree model of HBV prevention strategies utilised data from a cohort of 7071 pregnant women on the Thailand-Myanmar border using a provider perspective. All options included universal HBV vaccination for newborns in three strategies: (1) universal vaccination alone; (2) universal vaccination with screening of women during antenatal visits with rapid diagnostic test (RDT) plus HBV immune globulin (HBIG) administration to newborns of HBV surface antigen positive women; and (3) universal vaccination with screening of women during antenatal visits plus HBIG administration to newborns of women testing HBV e antigen positive by confirmatory test. At the time of the study, the HBIG after confirmatory test strategy was used. The costs in United States Dollars (US$), infections averted and incremental cost effectiveness ratios (ICERs) were calculated and sensitivity analyses were conducted. A willingness to pay threshold of US$1200 was used. The universal HBV vaccination was the least costly option at US$4.33 per woman attending the clinic. The HBIG after (RDT) strategy had an ICER of US$716.78 per infection averted. The HBIG after confirmatory test strategy was not cost-effective due to extended dominance. The one-way sensitivity analysis showed that while the transmission parameters and cost of HBIG had the biggest impact on outcomes, the HBIG after confirmatory test only became a cost-effective option when a low test cost was used or a high HBIG cost was used. The probabilistic sensitivity analysis showed that HBIG after RDT had an 87% likelihood of being cost-effective as compared to vaccination only at a willingness to pay threshold of US$1200. HBIG following confirmatory test is not a cost-effective strategy for preventing vertical transmission of HBV in the Thailand-Myanmar border population. By switching to HBIG following rapid diagnostic test, perinatal infections will be reduced by nearly one third. This strategy may be applicable to similar settings for marginalized populations where the confirmatory test is not logistically possible.

Ventilator-associated pneumonia (VAP) is a common healthcare-associated infection with high associated cost and poor patient outcomes. Many strategies for VAP reduction have been evaluated. However, the combination of strategies with the optimal cost-benefit ratio remains unknown. To determine the preferred VAP prevention strategy, both from the hospital and societal perspectives. A cost-benefit decision model with a Markov model was constructed. Baseline probability of VAP, death, reintubation, and discharge from the intensive care unit (ICU) alive were ascertained from clinical trial data. Model inputs were obtained from the medical literature and the U.S. Department of Labor; a device cost was obtained from the manufacturer. Sensitivity analyses were completed to test the robustness of model results. Overall least expensive strategy and the strategy with the best cost-benefit ratio, up to a willingness to pay threshold of $50,000-100,000 per case of VAP averted was sought. We examined a total of 120 unique combinations of VAP prevention strategies. The preferred strategy from the hospital perspective included subglottic suction endotracheal tubes, probiotics, and the Institute for Healthcare Improvement VAP Prevention Bundle. The preferred strategy from the point of view of society also included additional prevention measures (oral care with chlorhexidine and selective oral decontamination). No preferred strategies included silver endotracheal tubes or selective gut decontamination. Despite their infrequent use, current data suggest that the use of prophylactic probiotics and subglottic endotracheal tubes are cost-effective for preventing VAP from the societal and hospital perspectives.

The purpose of this research is to study any effects of managerial strategies on prevention of ketosis metabolic disorder in transition period in Shahroud commercial dairy farms. For this purpose, a questionnaire was prepared in order to obtain required information about the performance of these managerial strategies, performance costs, involvement situation with disorders relying upon clinical signs and treatment and health records, producing and economic situation, and fertility rate and its costs. The considered managerial guidelines include body condition score management or type evaluation in transition period, increase in dry matter intake close to parturition, using propylene glycol, using niacin, and high-quality feeding (the importance of feed quality) in transition period. Finally and upon arrangement of data, it was possible to study any effects of mentioned managerial strategies on related variants through multiple linear regressions. Furthermore, in order to study any relation among variables, we considered Pearson correlation coefficients as well. Finally, it was revealed that any application of managerial strategies for prevention from Ketosis in transition period has a significant effect in betterment of managerial and economic parameters.

A Framework for Valuing Investments in a Nurturing Society: Opportunities for Prevention Research.
Crowley, Max; Jones, Damon
2017-03-01
Investing in strategies that aim to build a more nurturing society offers tremendous opportunities for the field of prevention science. Yet, scientists struggle to consistently take their research beyond effectiveness evaluations and actually value the impact of preventive strategies. Ultimately, it is clear that convincing policymakers to make meaningful investments in children and youth will require estimates of the fiscal impact of such strategies across public service systems. The framework offered here values such investments. First, we review current public spending on children and families. Then, we describe how to quantify and monetize the impact of preventive interventions. This includes a new measurement strategy for assessing multisystem service utilization and a price list for key service provision from public education, social services, criminal justice, health care and tax systems.

The use antiretroviral reduces the sexual transmission of HIV, expanding interventions for serodiscordant couples. This article aims to review the use of antiretroviral and other prevention interventions among serodiscordant couples and to analyze its use in Brazil. A retrospective review was performed through the MEDLINE database and bases included in the Biblioteca Virtual em Saúde. The articles recovered exhibit four main strategies: (1) condom; (2) reduction of risks in sexual practices; (3) use of antiretrovirals, particularly early initiation of antiretroviral therapy (TASP) and pre-exposure prophylaxis (PrEP); (4) risk reduction in reproduction. TASP is highly effective in reducing sexual transmission, PrEP was tested in serodiscordant couples and both reduce the sexual transmission risk in different sexual practices, enabling individualized prevention strategies. When used in combination, antiretrovirals and sexual practices with condoms offer greater efficacy than any single strategy. The combined use of new and old strategies allows us to build a prevention policy for all.
Reducing Fatal Opioid Overdose: Prevention, Treatment and Harm Reduction Strategies
Hawk, Kathryn F.; Vaca, Federico E.; D’Onofrio, Gail
2015-01-01
The opioid overdose epidemic is a major threat to the public’s health, resulting in the development and implementation of a variety of strategies to reduce fatal overdose [1-3]. Many strategies are focused on primary prevention and increased access to effective treatment, although the past decade has seen an exponential increase in harm reduction initiatives. To maximize identification of opportunities for intervention, initiatives focusing on prevention, access to effective treatment, and harm reduction are examined independently, although considerable overlap exists. Particular attention is given to harm reduction approaches, as increased public and political will have facilitated widespread implementation of several initiatives, including increased distribution of naloxone and policy changes designed to increase bystander assistance during a witnessed overdose [4-7].

The leading cause of death among firefighters in the United States (U.S.) is cardiovascular events (CVEs) such as sudden cardiac arrest and myocardial infarction. This study compared the cost-effectiveness of three strategies to prevent CVEs among firefighters. We used a cost-effectiveness analysis model with published observational and clinical data, and cost quotes for physiologic monitoring devices to determine the cost-effectiveness of three CVE prevention strategies. We adopted the fire department administrator perspective and varied parameter estimates in one-way and two-way sensitivity analyses. A wellness-fitness program prevented 10% of CVEs, for an event rate of 0.9% at $1440 over 10-years, or an incremental cost-effectiveness ratio of $1.44 million per CVE prevented compared to no program. In one-way sensitivity analyses, monitoring was favored if costs were < $116/year. In two-way sensitivity analyses, monitoring was not favored if cost was ≥ $399/year. A wellness-fitness program was not favored if its preventive relative risk was >0.928. Wellness-fitness programs may be a cost-effective solution to preventing CVE among firefighters compared to real-time physiologic monitoring or doing nothing.

The current study explores community perspectives on alcohol abuse prevention strategies in rural Kenya. Data from focus group discussions with members of community organizations and in-depth interviews with a snowball sample of key informants revealed that rural communities view national alcohol abuse prevention interventions as ineffective and messages as unpersuasive in changing this high-risk behavior. The use of ethnic languages, stronger fear appeals, and visual aids were recommended for alcohol prevention messages aimed at communities with low literacy. Community members favored narratives and entertainment-education strategies, which are more engaging, and print media for their educational value. Health activism, although common, was viewed as less effective in motivating individuals to change drinking behavior but more effective in advocacy campaigns to pressure the government to enforce alcohol regulations. This study suggests further empirical research to inform evidence-based prevention campaigns and to understand how to communicate about alcohol-related health risks within communities that embrace alcohol consumption as a cultural norm.

To provide information from a review of literature about economic evaluations of preventive strategies for pressure injuries (PIs). This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to:1. Identify the purpose and methods used for this study.2. Compare costs and effectiveness related to preventative strategies for PIs. BACKGROUND: Pressure injuries (PIs) are a common and resource-intensive challenge for acute care hospitals worldwide. While a number of preventive strategies have the potential to reduce the cost of hospital-acquired PIs, it is unclear what approach is the most effective. The authors performed a narrative review of the literature on economic evaluations of preventive strategies to survey current findings and identify important factors in economic assessments. Ovid, MEDLINE, NHS Economic Evaluation Databases, and the Cochrane Database of Systematic ReviewsSELECTION CRITERIA: Potentially relevant original research articles and systematic reviews were considered. Selection criteria included articles that were written in English, provided data on cost or economic evaluations of preventive strategies of PIs in acute care, and published between January 2004 and September 2015. Data were abstracted from the articles using a standardized approach to evaluate how the items on the Consolidated Health Economic Evaluation Reporting Standards checklist were addressed. The searches identified 192 references. Thirty-three original articles were chosen for full-text reviews. Nineteen of these articles provided clear descriptions of interventions, study methods, and outcomes considered. Limitations in the available literature prevent firm conclusions from being reached about the relative economic merits of the various approaches to the prevention of PIs. The authors' review revealed a need for additional high-quality studies that adhere to commonly used standards of both currently utilized and emerging ways to prevent hospital-acquired PIs.
Interventions to prevent overweight in children.
Müller, M J; Danielzik, S; Landsberg, B; Pust, S

There are only few controlled studies on prevention of overweight in children and adolescence. These studies differ with respect to strategy, setting, duration, focus, variables of outcome and statistical power. Universal and school-based interventions show some improvement of health knowledge and health-related behaviours but they have only minor or no effects on nutritional status. However they reduce the incidence of overweight. The effects seem to be more pronounced in girls than in boys. Children of middle and high class as well as children with intact families benefit better from intervention than children with low socioeconomic status. Selected prevention in overweight children was most successful when children were treated together with their parents. However there are social barriers limiting the success. Simple interventions in a single area are unlikely to work on their own. The development of effective preventive interventions likely require strategies that affect multiple settings simultaneously. At present there is no concerted action but many strategies are followed in isolation. There is need for national campaigns and action plans on childhood overweight and obesity. It is tempting to speculate that this will also increase the effects of isolated approaches.

Mass media interventions are among the strategies recommended for youth cigarette smoking prevention, but little is known about optimal methods for reaching diverse youth audiences. Grades 4 through 12 samples of youth from four states (n = 1,230) rated smoking-prevention messages in classroom settings. Similar proportions of African American, Hispanic, and White youth participated. Impact of audience characteristics on message appeal ratings was assessed to provide guidance for audience segmentation strategies. Age had a strong effect on individual message appeal. The effect of gender also was significant. Message ratings were similar among the younger racial/ethnic groups, but differences were found for older African American youth. Lower academic achievement was associated with lower appeal scores for some messages. Age should be a primary consideration in developing and delivering smoking-prevention messages to youth audiences. The unique needs of boys and girls and older African American adolescents should also be considered.

Ventilator-associated pneumonia is associated with significant patient morbidity, mortality, and increased health care costs. In the current economic climate, it is crucial to implement cost-effective prevention strategies that have proven efficacy. Multiple prevention measures have been proposed by various expert panels. Global strategies have focused on infection control, and reduction of lower airway colonization with bacterial pathogens, intubation, duration of mechanical ventilation, and length of stay in the intensive care unit. Routine use of the Institute for Healthcare Improvement ventilator care bundle is widespread, and has been clearly demonstrated to be an effective method for reducing the incidence of ventilator-associated pneumonia. In this article, we examine specific aspects of the Institute for Healthcare Improvement bundle, better-designed endotracheal tubes, use of antibiotics and probiotics, and treatment of ventilator-associated tracheobronchitis to prevent ventilator-associated pneumonia.

Prerequisites for effective interventions against severe anaemia and malaria among infants are economic evaluations to aid the setting of priorities and the making of health policy. In the present study we analysed the cost and effectiveness of three control strategies hypothetically delivered through the Expanded Programme on Immunization (EPI). For the prevention of severe anaemia and from the perspective of the health provider, the cost-effectiveness ratios were, respectively, US$ 8, US$ 9, and US$ 21 per disability-adjusted life year (DALY) for malaria chemoprophylaxis with Deltaprim (a combination of 3.125 mg pyrimethamine and 25 mg dapsone) + iron, Deltaprim alone, or iron supplementation alone. For malaria prevention, Deltaprim + iron cost US$ 9.7 per DALY and Deltaprim alone cost US$ 10.2 per DALY. From a sociocultural perspective the cost-effectiveness ratios ranged from US$ 9 to US$ 26 for severe anaemia prevention and from US$ 11 to US$ 12 for the prevention of clinical malaria. These ratios were highly cost-effective, as defined by the World Bank's proposed threshold of less than US$ 25 per DALY for comparative assessments. Furthermore, all the preventive interventions were less costly than the current malaria and anaemia control strategies that rely on clinical case management. This economic analysis supports the inclusion of both malaria chemoprophylaxis and iron supplementation delivered through EPI as part of the control strategies for these major killers of infants in parts of sub-Saharan Africa.

Active and passive smoking are the first and third leading preventable causes of death. Many states are running or initiating antitobacco media campaigns. To review research on the effectiveness of different antismoking messages and published evidence of the effectiveness of paid antismoking advertising. Focus group studies conducted by professional advertising agencies that contract with California, Massachusetts, and Michigan to run their antismoking advertising campaigns, the Centers for Disease Control and Prevention's Media Campaign Resource Book, and copies of the advertisements. In total, we reviewed the results of 186 focus groups involving more than 1500 children and adults dealing with 118 advertisements that had actually been aired and additional concept advertisements that were not produced. Published literature was located using MEDLINE and standard bibliographic sources on the effectiveness of large, paid antitobacco media campaigns. We also reviewed reports and studies conducted by, or for, the California and Massachusetts health departments on program effectiveness, and conducted our own comparison of California vs Massachusetts using cigarette consumption data from the Tobacco Institute. All available studies. Eight advertising strategies to prevent people from starting to smoke and persuading them to stop were reviewed: industry manipulation, secondhand smoke, addiction, cessation, youth access, short-term effects, long-term health effects, and romantic rejection. These focus groups identified strategies that would be expected to be effective and ineffective. Regression analysis was used to compare the cost-effectiveness of the California and Massachusetts programs. Focus group participants indicated that industry manipulation and secondhand smoke are the most effective strategies for denormalizing smoking and reducing cigarette consumption. Addiction and cessation can be effective when used in conjunction with the industry manipulation and secondhand smoke strategies. Youth access, short-term effects, long-term health effects, and romantic rejection are not effective strategies. More aggressive advertising strategies appear to be more effective at reducing tobacco consumption.

Physical education (PE) teachers are at a high risk of musculoskeletal sports or work-related injuries because of the physical activity as inherent part of their profession. Such injuries have a negative impact on work and leisure time activities, and effective injury prevention interventions are needed. The present study aimed at testing the effectiveness of an injury prevention intervention that was developed and optimized according to PE teachers' wishes and values. Fifty-five PE teachers were randomly assigned to intervention or control group. Intervention group teachers engaged in two days of training during which they familiarized with eight injury prevention strategies (seven intrinsic and one extrinsic). A special feature of the intervention was that the way of delivery was based on the self-determination theory in order to stimulate participants' motivation to adhere to the proposed strategies. Prospective registrations during one school year were conducted concerning injuries and preventive behaviours. Results showed that the intervention group teachers had a lower number of injuries per 1000 h time of exposure (TOE) than the controls (INT: 0.49, CON: 1.14 injuries/1000 h TOE, OR: 2.32, 95% CI: 1.06-5.07), and applied a broader variety of strategies including dynamic and static stretching, core stability, balance and strength training, when compared to the controls who mainly engaged in warming-up. In conclusion, with the same amount of time, an injury reduction was found in PE teachers through a more balanced use of provided preventive strategies.

2017-01-01
We propose and analyze a compartmental nonlinear deterministic mathematical model for the typhoid fever outbreak and optimal control strategies in a community with varying population. The model is studied qualitatively using stability theory of differential equations and the basic reproductive number that represents the epidemic indicator is obtained from the largest eigenvalue of the next-generation matrix. Both local and global asymptotic stability conditions for disease-free and endemic equilibria are determined. The model exhibits a forward transcritical bifurcation and the sensitivity analysis is performed. The optimal control problem is designed by applying Pontryagin maximum principle with three control strategies, namely, the prevention strategy through sanitation, proper hygiene, and vaccination; the treatment strategy through application of appropriate medicine; and the screening of the carriers. The cost functional accounts for the cost involved in prevention, screening, and treatment together with the total number of the infected persons averted. Numerical results for the typhoid outbreak dynamics and its optimal control revealed that a combination of prevention and treatment is the best cost-effective strategy to eradicate the disease.
Challenges in pressure ulcer prevention.

Although this article is a stand-alone article, it sets the scene for later articles in this issue. Pressure ulcers are considered to be a largely preventable problem, and yet despite extensive training and the expenditure of a large amount of resources, they persist. This article reviews the current understanding of pressure ulcer aetiology: pressure, shear and microclimate. Individual risk factors for pressure ulceration also need to be understood in order to determine the level of risk of an individual. Such an assessment is essential to determine appropriate prevention strategies. The main prevention strategies in terms of reducing pressure and shear and managing microclimate are studied in this article. The problem of pressure ulceration related to medical devices is also considered as most of the standard prevention strategies are not effective in preventing this type of damage. Finally, the possibility of using dressings as an additional preventive strategy is raised along with the question: is there enough evidence to support their use? © 2013 The Authors.

: For parenting programs to achieve a public health impact, it is necessary to develop more effective marketing strategies to increase public awareness of these programs and promote parental participation. In this article, we compared a promotion-focused and a prevention-focused strategy via two studies. : We designed two ads inviting parents to participate in a universal parenting program; one ad focused on the program increasing the likelihood of positive outcomes for children (promotion-focused) and the other on the program reducing the likelihood of negative outcomes (prevention-focused). In study I, the two ads were run online simultaneously. Those who clicked on an ad were directed to a website where they could read about and sign up for the program. In study II, a community sample of 706 parents answered a questionnaire about the ads. : In study I, over 85 days, the prevention ad generated more clicks. There was no difference in the number of pages visited on the website nor in the number of parents who signed up for the program. In study II, parents showed a preference for the promotion ad, perceiving it as more relevant and rating it as more effective in getting them interested in the program. : A prevention strategy may be more effective in drawing public attention, in general. However, a promotion strategy is more likely to reach parents, in particular, and inspire them to consider participating in parenting programs. These strategies should be developed further and tested in both general and clinical populations. © The Author 2016.

Resource Effective Strategies to Prevent and Treat Cardiovascular Disease
Schwalm, Jon-David; McKee, Martin; Huffman, Mark D.; Yusuf, Salim
2016-01-01
Cardiovascular disease (CVD) is the leading cause of global deaths, with the majority occurring in low- and middle-income countries (LMIC). The primary and secondary prevention of CVD is suboptimal throughout the world, but the evidence-practice gaps are much more pronounced in LMIC. Barriers at the patient, health-care provider, and health system level prevent the implementation of optimal primary and secondary prevention. Identification of the particular barriers that exist in resource-constrained settings is necessary to inform effective strategies to reduce the identified evidence-practice gaps. Furthermore, targeting modifiable factors that contribute most significantly to the global burden of CVD, including tobacco use, hypertension, and secondary prevention for CVD will lead to the biggest gains in mortality reduction. We review a select number of novel, resource-efficient strategies to reduce premature mortality from CVD, including: (1) effective measures for tobacco control; (2) implementation of simplified screening and management algorithms for those with or at risk of CVD, (3) increasing the availability and affordability of simplified and cost-effective treatment regimens including combination CVD preventive drug therapy, and (4) simplified delivery of health care through task-sharing (non-physician health workers) and optimizing self-management (treatment supporters). Developing and deploying systems of care that address barriers related to the above, will lead to substantial reductions in CVD and related mortality. PMID:26903017

The Prevention of Schizophrenia—What Can We Learn From Eco-Epidemiology?
Kirkbride, James B.; Jones, Peter B.
2011-01-01
The search for the causes of schizophrenia has predominantly originated from 2 research paradigms; genetics and epidemiology. While each approach has made important contributions to etiological understanding, neither has fully resolved the exact milieu of risk factors for schizophrenia, and there is growing recognition that several pathways to the onset of such disorders may exist. Eco-epidemiology offers an integrative framework to study schizophrenia etiology, incorporating multiple, interactive levels of causation, including genetic, epigenetic, individual, familial, community, and societal domains over the life course. In this article, we review the current evidence base, through the lens of eco-epidemiology, to determine whether it warrants the design and implementation of putative prevention strategies for schizophrenia. We argue that while there are potentially large public health gains available, we do not currently have sufficient empirical data to design effective prevention strategies. It will be important for the research community to more fully elucidate the likely multifactorial, multilevel, polygenetic, and eco-epidemiological basis of schizophrenia before we can design useful prevention strategies. We conclude by speculating on the forms effective strategies might take. PMID:20974748
Alertness management in two-person long-haul flight operations

1992-01-01
Long-haul flight operations involve cumulative sleep loss, circadian disruption, and extended and irregular duty schedules. These factors reduce pilot alertness and performance on the flightdeck. Conceptually and operationally, alertness management in flight operations can be divided into preventive strategies and operational countermeasures. Preventive strategies are utilized prior to a duty period to mitigate or reduce the effects of sleep loss, circadian disruption and fatigue during subsequent flight operations. Operational countermeasures are used during operations as acute techniques for maintaining performance and alertness. Results from previous NASA Ames field studies document the sleep loss and circadian disruption in three-person long-haul flying and illustrate the application of preventive strategies and operational countermeasures. One strategy that can be used in both a preventive and operational manner is strategic napping. The application and effectiveness of strategic napping in long-haul operations will be discussed. Finally, long-haul flying in two-person highly automated aircraft capable of extended range operations will create new challenges to maintaining pilot alertness and performance. Alertness management issues in this flight environment will be explored.
Mechanism-based strategies for protein thermostabilization.
Mozhaev, V V
1993-03-01
Strategies for stabilizing enzymes can be derived from a two-step model of irreversible inactivation that involves preliminary reversible unfolding, followed by an irreversible step. Reversible unfolding is best prevented by covalent immobilization, whereas methods such as covalent modification of amino acid residues or 'medium engineering' (by the addition of low-molecular-weight compounds) are effective against irreversible 'incorrect' refolding. Genetic modification of the protein sequence is the most effective approach for preventing chemical deterioration.
A Framework for Valuing Investments in a Nurturing Society: Opportunities for Prevention Research
Crowley, Max; Jones, Damon
2017-01-01
Investing in strategies that aim to build a more nurturing society offers tremendous opportunities for the field of prevention science. Yet, scientists struggle to consistently take their research beyond effectiveness evaluations and actually value the impact of preventive strategies. Ultimately, it is clear that convincing policymakers to make meaningful investments in children and youth will require estimates of the fiscal impact of such strategies across public service systems. The framework offered here values such investments. First, we review current public spending on children and families. Then, we describe how to quantify and monetize the impact of preventive interventions. This includes a new measurement strategy for assessing multi-system service utilization and a price list for key service provision from public education, social services, criminal justice, healthcare, and tax systems.

The cost-effectiveness of alternating pressure-relieving devices, mattress replacements, and mattress overlays compared with a standard hospital (high-specification foam mattress) for the prevention and treatment of pressure ulcers in hospital patients in the United Kingdom was investigated. A decision-analytic model was constructed to evaluate different strategies to prevent or treat pressure ulcers. Three scenarios were evaluated: the prevention of pressure ulcers, the treatment of superficial ulcers, and the treatment of severe ulcers. Epidemiological and effectiveness data were obtained from the clinical literature. Expert opinion using a rating scale technique was used to obtain quality of life data. Costs of the devices were obtained from manufacturers, whereas costs of treatment were obtained from the literature. Uncertainty was explored through probabilistic sensitivity analysis. Using 30,000 pounds sterling/QALY (quality-adjusted life year) as the decision-maker's cut off point (the current UK standard), in scenario 1 (prevention), the cost-effective strategy was the mattress overlay at 1, 4, and 12 weeks. In scenarios 2 and 3, the cost-effective strategy was the mattress replacement at 1, 4, and 12 weeks. Standard care was a dominated intervention in all scenarios for values of the decision-maker's ceiling ratio ranging from 5,000 pounds sterling to 100,000 pounds sterling/QALY. However, the probabilistic sensitivity analysis results reflected the high uncertainty surrounding the choice of devices. Current information suggests that alternating pressure mattress overlays may be cost-effective for the prevention of pressure ulcers, whereas alternating pressure mattress replacements appears to be cost-effective for the treatment of superficial and severe pressure ulcers.

We attempted to determine whether multimedia fall prevention education using different instructional strategies increases older adults' knowledge of fall threats and their fall prevention behaviors. Fifty-three community-dwelling older adults were randomized to iwo educational groups or a control group. Multimedia-based educational interventions to increase fall threats knowledge and encourage fall prevention behaviors had two tailoring strategies: (1) improve content realism for individual learners (authenticity group) and (2) highlight program goals and benefits while using participants' content selections (motivation group). Knowledge was measured at baseline and 1-mo follow-up. Participants recorded prevention behaviors for 1 mo. Intervention group participants showed greater knowledge gains and posttest knowledge than did control group participants. The motivation group engaged in more prevention behaviors over 1 mo than did the other groups. Tailoring fall prevention education by addressing authenticity and motivation successfully improved fall threats knowledge. Combining motivational strategies with multimedia education increased the effectiveness of the intervention in encouraging fall prevention behaviors.
Comprehensive Sexuality Education as a Primary Prevention Strategy for Sexual Violence Perpetration.
Schneider, Madeline; Hirsch, Jennifer S
2018-01-01
Sexual violence (SV) represents a serious public health problem with high rates and numerous health consequences. Current primary prevention strategies to reduce SV perpetration have been shown to be largely ineffective-not surprisingly, since as others have pointed out current prevention largely fails to draw on existing knowledge about the characteristics of effective prevention. In this article, we examine the potential of K-12 comprehensive sexuality education (CSE), guided by the National Sexuality Education Standards (NSES), to be an effective strategy. Our discussion uses socioecological and feminist theories as a guide, examines the extent to which NSES-guided CSE could both meet the qualities of effective prevention programs and mitigate the risk factors that are most implicated in perpetration behavior, and considers the potential limitations of this approach. We suggest that sequential, K-12 program has potential to prevent the emergence of risk factors associated with SV perpetration by starting prevention early on in the life course. CSE has not yet been evaluated with SV perpetration behavior as an outcome, and this article synthesizes what is known about drivers of SV perpetration and the potential impacts of CSE to argue for the importance of future research in this area. The primary recommendation is for longitudinal research to examine the impact of CSE on SV perpetration as well as on other sexual and reproductive health outcomes.

As part of a larger study to examine the feasibility and acceptability of a couples-based HIV-prevention intervention, we conducted formative in-depth interviews with 10 couples to explore topics such as challenges in practising safer sex, HIV-prevention strategies, gender power and violence, and issues of trust and infidelity. In this study, both men and women perceived infidelity as ubiquitous in their social context and were therefore unable to discuss HIV risk and prevention without suspicions of infidelity in their own relationship. This impacted couples’ ability openly and effectively to discuss strategies to prevent HIV and thus may have contributed to the limited uptake of HIV-prevention strategies, such as condom use and HIV testing. The contentious nature of safe-sex discussions placed both members of the couple at a higher risk for HIV acquisition within the partnership. This study sheds light on how existing relationship norms in South Africa influence HIV-prevention communication within couples and suggests that new ways of approaching conflictual issues such as mistrust and infidelity are vital in order for HIV-prevention programmes to succeed.

To assess the cost effectiveness of two repositioning strategies and inform the 2014 National Institute for Health and Care Excellence clinical guideline recommendations on pressure ulcer prevention. Pressure ulcers are distressing events, caused when skin and underlying tissues are placed under pressure sufficient to impair blood supply. They can have a substantial impact on quality of life and have significant resource implications. Repositioning is a key prevention strategy, but can be resource intensive, leading to variation in practice. This economic analysis was conducted to identify the most cost-effective repositioning strategy for the prevention of pressure ulcers. The economic analysis took the form of a cost-utility model. The clinical inputs to the model were taken from a systematic review of clinical data. The population in the model was older people in a nursing home. The economic model was developed with members of the guideline development group and included costs borne by the UK National Health Service. Outcomes were expressed as costs and quality adjusted life years. Despite being marginally more clinically effective, alternating 2 and 4 hourly repositioning is not a cost-effective use of UK National Health Service resources (compared with 4 hourly repositioning) for this high risk group of patients at a cost-effectiveness threshold of £20,000 per quality adjusted life years. These results were used to inform the clinical guideline recommendations for those who are at high risk of developing pressure ulcers. © 2015 John Wiley & Sons Ltd.
Typhoid fever vaccination strategies.
Date, Kashmira A; Bentsi-Enchill, Adwoa; Marks, Florian; Fox, Kimberley
2015-06-19
Typhoid vaccination is an important component of typhoid fever prevention and control, and is recommended for public health programmatic use in both endemic and outbreak settings. We reviewed experiences with various vaccination strategies using the currently available typhoid vaccines (injectable Vi polysaccharide vaccine [ViPS], oral Ty21a vaccine, and injectable typhoid conjugate vaccine [TCV]). We assessed the rationale, acceptability, effectiveness, impact and implementation lessons of these strategies to inform effective typhoid vaccination strategies for the future. Vaccination strategies were categorized by vaccine disease control strategy (preemptive use for endemic disease or to prevent an outbreak, and reactive use for outbreak control) and vaccine delivery strategy (community-based routine, community-based campaign and school-based). Almost all public health typhoid vaccination programs used ViPS vaccine and have been in countries of Asia, with one example in the Pacific and one experience using the Ty21a vaccine in South America. All vaccination strategies were found to be acceptable, feasible and effective in the settings evaluated; evidence of impact, where available, was strongest in endemic settings and in the short- to medium-term. Vaccination was cost-effective in high-incidence but not low-incidence settings. Experience in disaster and outbreak settings remains limited. TCVs have recently become available and none are WHO-prequalified yet; no program experience with TCVs was found in published literature. Despite the demonstrated success of several typhoid vaccination strategies, typhoid vaccines remain underused. Implementation lessons should be applied to design optimal vaccination strategies using TCVs which have several anticipated advantages, such as potential for use in infant immunization programs and longer duration of protection, over the ViPS and Ty21a vaccines for typhoid prevention and control.

Based on earlier studies of ski injury, which indicated that youths were at increased risk of injury, that males were most likely to injure the head or face and that females were most likely to injure the knee, a study to identify factors relevant for physicians to use in injury prevention initiatives was undertaken. The authors then conducted a search for effective injury prevention strategies using MEDLINE. The results of both undertakings were the basis for proposed guidelines for prevention strategies that physicians can use when counselling skiers and snowboarders. PMID:20401274

The incidence of Clostridium difficile-associated diarrhoea (CDAD) in hospitalized children and adolescents has been increasing year-on-year. Paediatric CDAD represents a significant economic burden on healthcare systems. Probiotics are live organisms thought to improve the microbial balance of the host, counteract disturbances in intestinal flora, and reduce the risk of colonization by pathogenic bacteria. We conducted a cost-effectiveness analysis to assess the economy of probiotics for the prevention of CDAD in children and adolescents receiving antibiotics. A decision tree model combined clinical effectiveness, utility, and cost data was used. Sensitivity analyses were conducted to determine the robustness of the model outcomes. The Oral probiotics strategy and No probiotics strategy offered patients 0.05876 and 0.056 QALY at a cost of $16668.70 and $20355.28, respectively. The Oral probiotics strategy exhibited higher QALY and lower cost, so it is the cost-saving strategy. The results were robust for sensitivity analyses. From the perspective of the medical system, oral probiotics as a preventive strategy for CDAD in hospitalized children and adolescents who are receiving a therapeutic course of antibiotics reduced the risk of CDAD, and it is a cost-saving strategy.

Background Poor oral health has been a persistent problem in nursing home residents for decades, with severe consequences for residents and the health care system. Two major barriers to providing appropriate oral care are residents’ responsive behaviors to oral care and residents’ lack of ability or motivation to perform oral care on their own. Objectives To evaluate the effectiveness of strategies that nursing home care providers can apply to either prevent/overcome residents’ responsive behaviors to oral care, or enable/motivate residents to perform their own oral care. Materials and methods We searched the databases Medline, EMBASE, Evidence Based Reviews–Cochrane Central Register of Controlled Trials, CINAHL, and Web of Science for intervention studies assessing the effectiveness of eligible strategies. Two reviewers independently (a) screened titles, abstracts and retrieved full-texts; (b) searched key journal contents, key author publications, and reference lists of all included studies; and (c) assessed methodological quality of included studies. Discrepancies at any stage were resolved by consensus. We conducted a narrative synthesis of study results. Results We included three one-group pre-test, post-test studies, and one cross-sectional study. Methodological quality was low (n = 3) and low moderate (n = 1). Two studies assessed strategies to enable/motivate nursing home residents to perform their own oral care, and to studies assessed strategies to prevent or overcome responsive behaviors to oral care. All studies reported improvements of at least some of the outcomes measured, but interpretation is limited due to methodological problems. Conclusions Potentially promising strategies are available that nursing home care providers can apply to prevent/overcome residents’ responsive behaviors to oral care or to enable/motivate residents to perform their own oral care. However, studies assessing these strategies have a high risk for bias. To overcome oral health problems in nursing homes, care providers will need practical strategies whose effectiveness was assessed in robust studies. PMID:28609476
Caught in the Web: A Review of Web-Based Suicide Prevention
Lai, Mee Huong; Maniam, Thambu; Ravindran, Arun V
2014-01-01
Background Suicide is a serious and increasing problem worldwide. The emergence of the digital world has had a tremendous impact on people’s lives, both negative and positive, including an impact on suicidal behaviors. Objective Our aim was to perform a review of the published literature on Web-based suicide prevention strategies, focusing on their efficacy, benefits, and challenges. Methods The EBSCOhost (Medline, PsycINFO, CINAHL), OvidSP, the Cochrane Library, and ScienceDirect databases were searched for literature regarding Web-based suicide prevention strategies from 1997 to 2013 according to the modified PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. The selected articles were subjected to quality rating and data extraction. Results Good quality literature was surprisingly sparse, with only 15 fulfilling criteria for inclusion in the review, and most were rated as being medium to low quality. Internet-based cognitive behavior therapy (iCBT) reduced suicidal ideation in the general population in two randomized controlled trial (effect sizes, d=0.04-0.45) and in a clinical audit of depressed primary care patients. Descriptive studies reported improved accessibility and reduced barriers to treatment with Internet among students. Besides automated iCBT, preventive strategies were mainly interactive (email communication, online individual or supervised group support) or information-based (website postings). The benefits and potential challenges of accessibility, anonymity, and text-based communication as key components for Web-based suicide prevention strategies were emphasized. Conclusions There is preliminary evidence that suggests the probable benefit of Web-based strategies in suicide prevention. Future larger systematic research is needed to confirm the effectiveness and risk benefit ratio of such strategies. PMID:24472876
[Prevention of allergic diseases in childhood: from theory to reality].
2016-06-01
Allergic diseases have an increasing worldwide prevalence and a great impact on the health related costs. The research is focused on the study of etiological and risk factors of allergic diseases that can potentially be modified with primary, secondary and tertiary prevention strategies. Many of these measures do not have a definitively proven effect taking place in a controlled context different to what happens in real life. This paper aims to review the latest evidence on prevention of allergic diseases considering certainties and unresolved issues and focuses mainly on environmental, dietary, pharmacological and immunological preventive strategies for different levels of prevention. It is imperative to have a better understanding of genetic and environmental factors that cause allergic diseases to optimize preventive measures that are effective in reversing the increasing trend in the prevalence of allergic illnesses in childhood.

The costs of HIV prevention strategies in developing countries.
Söderlund, N.; Lavis, J.; Broomberg, J.; Mills, A.
1993-01-01
Since many evaluations of HIV (human immunodeficiency virus) prevention programmes do not include data on costs, a preliminary analysis of the costs and outputs of a sample of HIV prevention projects was attempted. Case studies, representing six broad HIV prevention strategies in developing countries with differing levels of per capita gross domestic product, were sought on the basis of availability of data and potential generalizability. The six prevention strategies studied were mass media campaigns, peer education programmes, sexually transmitted disease treatment, condom social marketing, safe blood provision, and needle exchange/bleach provision programmes. Financial cost data were abstracted from published studies or were obtained directly from project coordinators. Although estimates of cost-effectiveness were not made, calculations of the relative cost per common process measure of output were compared. Condom distribution costs ranged from US$ 0.02 to 0.70 per condom distributed, and costs of strategies involving personal educational input ranged from US$ 0.15 to 12.59 per contact. PMID:8261563

This meta-analysis tested the major theoretical assumptions about behavior change by examining the outcomes and mediating mechanisms of different preventive strategies in a sample of 354 HIV-prevention interventions and 99 control groups, spanning the past 17 years. There were 2 main conclusions from this extensive review. First, the most effective interventions were those that contained attitudinal arguments, educational information, behavioral skills arguments, and behavioral skills training, whereas the least effective ones were those that attempted to induce fear of HIV. Second, the impact of the interventions and the different strategies behind them was contingent on the gender, age, ethnicity, risk group, and past condom use of the target audience in ways that illuminate the direction of future preventive efforts.

Delirium is the most prevalent neuropsychiatric syndrome in the general hospital. Its presence is a marker of poor prognosis for patients. Its prevention could be the most effective strategy for reducing its frequency and its complications. To review recent findings and strategies for the prevention of delirium. A non-systematic review of scientific articles published in the last ten years in Spanish and English. A search was made in databases such as MEDLINE, Cochrane, EMBASE, Ovid, and ScienceDirect, for articles that included the terms, delirium and prevention. Identification of predisposing and precipitating factors for delirium and a better understanding of the pathophysiological mechanisms underlying the onset of delirium have enabled the implementation of various pharmacological and non-pharmacological strategies in patients at high risk to develop hospital delirium. The studies to prevent delirium have focused on surgical patients. The current evidence supports the daily implementation of non-pharmacological measures to prevent delirium, as they are easy and cost effective. The available evidence is still limited to recommend the daily use of pharmacological strategies in delirium prophylaxis, and there is a consensus against the modest use of antipsychotic drugs in surgical patients and dexmedetomidine in patients in intensive care. New high-quality clinical trials and studies involving non-surgical patients are needed to provide more evidence about this subject. Copyright © 2015 Asociación Colombiana de Psiquiatría.

Neuromuscular preventive training programs effectively reduce injury and improve performance in youth athletes. However, program effectiveness is directly linked to program compliance, fidelity, and dosage. Preventive training programs are not widely adopted by youth sport coaches. One way to promote widespread dissemination and compliance is to identify implementation strategies that influence program adoption and maintenance. It is unknown how previously published programs have followed the elements of an implementation framework. The objective of this review was to evaluate how elements of the 7 steps of implementation, developed by Padua et al, have been performed in the evidence of lower extremity preventive training programs. A systematic review of the literature from 1996 through September 2016 was conducted using electronic databases. Investigations that documented implementation of a sport team-based neuromuscular preventive training program in youth athletes and measured lower extremity injury rates were included. Clinical review. Level 4. A total of 12 studies met the inclusion criteria and were reviewed. Information regarding the completion of any of the 7 steps within the implementation framework developed by Padua et al was extracted. None of the 12 articles documented completion of all 7 steps. While each study addressed some of the 7 steps, no study addressed maintenance or an exit strategy for youth athletes. Program implementation appears limited in obtaining administrative support, utilizing an interdisciplinary implementation team, and monitoring or promoting fidelity of the intervention. Despite strong evidence supporting the effectiveness of preventive training programs in youth athletes, there is a gap between short-term improvements and long-term implementation strategies. Future interventions should include all 7 steps of the implementation framework to promote transparent dissemination of preventive training programs.
Population-based prevention of eating disorders: an application of the Rose prevention model.
Austin, S B
2001-03-01
Several decades of concerted research on eating disorders have generated a broad range of proposed causal influences, but much of this etiologic research does not elucidate practical avenues for preventive interventions. Translating etiologic theory into community health interventions depends on the identification of key leverage points, factors that are amenable to public health intervention and provide an opportunity to maximize impact on the outcome of interest. Population-based preventive strategies, elaborated by epidemiologist Geoffrey Rose, can maximize the impact of public health interventions. In the case of eating disorders, Rose's model is instructive: Dieting stands out as risk behavior that may both fit Rose's model well and be a key leverage point for preventive intervention. Grounded in Rose's work, this article lodges a theoretical argument for the population-based prevention of eating disorders. In the introductory section, existing research on the epidemiology of dieting is reviewed, showing that it is extremely common among adolescent girls and women and that the behavior has been implicated as a causal factor for disordered eating. Next, new evidence is offered to build a case for how a population-wide reduction in dieting may be an effective strategy for prevention of eating pathology. Finally Rose's prevention framework is used to introduce a unique and provocative perspective on the prevention of eating disorders. Dieting is a normative behavior in our culture with psychological and physiological effects in the causal chain leading to eating pathology. This behavior may represent an ideal target for population-based prevention. Theoretical and empirical evidence suggests that a population-wide reduction in dieting may be a justifiable and effective strategy for prevention of eating pathology.

The relationship between hand hygiene and health care-associated infection: it’s complicated
McLaws, Mary-Louise
2015-01-01
The reasoning that improved hand hygiene compliance contributes to the prevention of health care-associated infections is widely accepted. It is also accepted that high hand hygiene alone cannot impact formidable risk factors, such as older age, immunosuppression, admission to the intensive care unit, longer length of stay, and indwelling devices. When hand hygiene interventions are concurrently undertaken with other routine or special preventive strategies, there is a potential for these concurrent strategies to confound the effect of the hand hygiene program. The result may be an overestimation of the hand hygiene intervention unless the design of the intervention or analysis controls the effect of the potential confounders. Other epidemiologic principles that may also impact the result of a hand hygiene program include failure to consider measurement error of the content of the hand hygiene program and the measurement error of compliance. Some epidemiological errors in hand hygiene programs aimed at reducing health care-associated infections are inherent and not easily controlled. Nevertheless, the inadvertent omission by authors to report these common epidemiological errors, including concurrent infection prevention strategies, suggests to readers that the effect of hand hygiene is greater than the sum of all infection prevention strategies. Worse still, this omission does not assist evidence-based practice. PMID:25678805

Abstract Preventing neural tube defects (NTDs) easily qualifies as a high‐value opportunity to improve childhood survival and health: the unmet need is significant (major preventable burden), the intervention is transformative (providing sufficient folic acid), and delivery strategies (e.g., fortification) are effective in low‐resource countries. Yet, NTD prevention is lagging. Can public health surveillance help fix this problem? Critics contend that surveillance is largely unnecessary, that limited resources are best spent on interventions, and that surveillance is unrealistic in developing countries. The counterargument is twofold: (1) in the absence of surveillance, interventions will provide fewer benefits and cost more and (2) effective surveillance is likely possible nearly everywhere, with appropriate strategies. As a base strategy, we propose “triple surveillance:” integrating surveillance of cause (folate insufficiency), of disease occurrence (NTD prevalence), and of health outcomes (morbidity, mortality, and disability). For better sustainability and usefulness, it is crucial to refocus and streamline surveillance activities (no recreational data collection), weave surveillance into clinical care (integrate in clinical workflow), and, later, work on including additional risk factors and pediatric outcomes (increase benefits at low marginal cost). By doing so, surveillance becomes not a roadblock but a preferential path to prevention and better care. PMID:29532515

Cardiac surgery patients colonized with Staphylococcus aureus have a greater risk of surgical site infection (SSI). The purpose of this study was to evaluate the cost-effectiveness of decolonization strategies to prevent SSIs. We compared three decolonization strategies: universal decolonization (UD), all subjects treated; targeted decolonization (TD), only S aureus carriers treated; and no decolonization (ND). Decolonization included mupirocin, chlorhexidine, and vancomycin. We implemented a decision tree comparing the costs and quality-adjusted life-years (QALYs) of these strategies on SSI over a 1-year period for subjects undergoing coronary artery bypass graft surgery from a US health sector perspective. Deterministic and probabilistic sensitivity analyses were conducted to address the uncertainty in the variables. Universal decolonization was the dominant strategy because it resulted in reduced costs at near-equal QALYs compared with TD and ND. Compared with ND, UD decreased costs by $462 and increased QALYs by 0.002 per subject, whereas TD decreased costs by $205 and increased QALYs by 0.001 per subject. For 1,000 subjects, UD prevented 19 SSI and TD prevented 10 SSI compared with ND. Sensitivity analysis showed UD to be the most cost-effective strategy in more than 91% of simulations. For the 220,000 coronary artery bypass graft procedures performed yearly in the United States, UD would save $102 million whereas TD would save $45 million compared with ND. Universal decolonization outperforms other strategies. However, the potential costs savings of $57 million per 220,000 coronary artery bypass graft procedures comparing UD versus TD must be weighed against the potential risk of developing resistance associated with universal decolonization.

Several countries have recently established multistakeholder strategies to prevent or control overweight and obesity; however, studies have not yet been done on their effectiveness and likely impact. This study's objectives were to (i) explore sector-wide benefits and impacts likely to accrue from implementing an obesity prevention strategy in the Australian state of New South Wales; (ii) discuss the wider implications of the findings for research and practice; and (iii) strengthen the case for sustained implementation of a comprehensive, intersectoral approach. A case study approach, including evidence reviews and illustrative epidemiological models, was used to show potential benefits from meeting selected targets and objectives specified in the strategy. For adults, improved health outcomes potentially include reductions in all-cause mortality, cardiovascular disease, type 2 diabetes, various cancers, osteoarthritis, infant mortality and healthcare costs. Potential benefits beyond the health sector involve disability payments, absenteeism, worker productivity, workplace injuries and insurance claims. For children and adolescents, improved health outcomes potentially include metabolic risk factors, dental health, prehypertension/hypertension, cardiovascular disease risk factors, depression, rates of mortality in hospitalised children, bullying and otitis media. Sector-wide health, social and economic benefits from successful implementation of multisector obesity prevention strategies are likely to be substantial if specified targets are achieved. Epidemiological modelling described in this paper for selected examples provides illustrative rather than comprehensive evidence for potential benefits. Process evaluation of the extent of implementation of these multisectoral strategies, together with the accumulated data on intervention effectiveness, will determine their potential population health benefit. Quantifying the health and social benefits that are likely to accrue if comprehensive sector-wide obesity prevention and control strategies are established can strengthen advocacy for their sustained implementation.

Abstract Over the last decade, there has been a growing appreciation of the importance of identifying and treating cognitive impairment associated with bipolar disorder, since it persists in remission periods. Evidence indicates that neurocognitive dysfunction may significantly influence patients’ psychosocial outcomes. An ever-increasing body of research seeks to achieve a better understanding of potential moderators contributing to cognitive impairment in bipolar disorder in order to develop prevention strategies and effective treatments. This review provides an overview of the available data from studies examining treatments for cognitive dysfunction in bipolar disorder as well as potential novel treatments, from both pharmacological and psychological perspectives. All these data encourage the development of further studies to find effective strategies to prevent and treat cognitive impairment associated with bipolar disorder. These efforts may ultimately lead to an improvement of psychosocial functioning in these patients. PMID:28498954
Effectively engaging stakeholders and the public in developing violence prevention messages.

Preventing family violence requires that stakeholders and the broader public be involved in developing evidence-based violence prevention strategies. However, gaps exist in between what we know (knowledge), what we do (action), and the structures supporting practice (policy). We discuss the broad challenge of mobilizing knowledge-for-action in family violence, with a primary focus on the issue of how stakeholders and the public can be effectively engaged when developing and communicating evidence-based violence prevention messages. We suggest that a comprehensive approach to stakeholder and public engagement in developing violence prevention messages includes: 1) clear and consistent messaging; 2) identifying and using, as appropriate, lessons from campaigns that show evidence of reducing specific types of violence; and 3) evidence-informed approaches for communicating to specific groups. Components of a comprehensive approach must take into account the available research evidence, implementation feasibility, and the context-specific nature of family violence. While strategies exist for engaging stakeholders and the public in messaging about family violence prevention, knowledge mobilization must be informed by evidence, dialogue with stakeholders, and proactive media strategies. This paper will be of interest to public health practitioners or others involved in planning and implementing violence prevention programs because it highlights what is known about the issue, potential solutions, and implementation considerations.
Prevention and early recognition: the role of family pediatrician.
Moretti, Carlo; Foltran, Francesca
2012-05-14
Even if it is empirically evident that pediatricians play a key role in diagnosis, treatment and prevention of FB injuries, almost all studies have focused on the subset of injured children who receive medical care in the hospital or in the Emergency Department; moreover, a lack of scientific interest to improve information about pediatric injuries in primary care seems to exist. Primary care physicians can play an important role if they promptly identify suspect unrecognized FB aspiration in children. Moreover, prevention is a cornerstone of pediatric practice, and pediatricians, as reliable sources of information, may be efficacious in promoting injury prevention message. Given the paucity of works finalized to evaluate the role of injury preventive strategies in primary care it is arduous to identify an ideal approach to implement counseling strategies. However, evidences obtained elsewhere have suggested that effective preventive strategy origins from an effective communication technique, moreover, the probability of success is greater when the attention toward the problem is greater; particularly, the postpartum period is a time of tremendous change, increased health problems, and emotional upheaval for new parents. General practitioners are in an ideal position to assist families during this period and may consider a sooner rather than later, approach to injury prevention education.

Background Falls are a significant threat to the safety, health and independence of older citizens. Despite the now substantial evidence about effective falls prevention interventions, translation into falls reductions has not yet been fully realised. While the hip fracture rate is decreasing, the number and rate of fall-related hospital admissions among older people is increasing. The challenge now is to deliver the most effective interventions efficiently at a population level, and for these interventions to be taken up by older people. Objective To support the development, and evaluation of, effective falls prevention policy and practice in the state of Victoria, Australia. Methods The RE-AIM model (Reach, Efficacy, Adoption, Implementation, Maintenance) was used to identify strategies for an effective programme. Research objectives were developed to support the strategies. These include: (1) identification of subgroups of older people most frequently admitted to hospital for falls; (2) examining the acceptability of established falls interventions; (3) identification of factors that encourage and support relevant lifestyle changes; (4) identifying opportunities to incorporate confirmed interventions in existing programmes and services; (5) developing guidelines for sustainability. The research results will subsequently guide strategy details for the falls prevention plan. RE-AIM will provide the framework for the evaluation structure. Outcome measures Measures to monitor the implementation of the selected interventions will be determined for each intervention, based on the five key factors of the RE-AIM model. The overall effect of the falls prevention plan will be monitored by time series analysis of fall-related hospital admission rates for community-dwelling older people. PMID:21186224

School-based programs targeting the prevention of tobacco use are a key strategy for reducing the overall tobacco-related mortality and morbidity in the community. While substantial research investment has resulted in the identification of various effective tobacco prevention interventions in schools, this research investment will not result in public health benefits, unless effectively disseminated and implemented. This rapid review aimed to identify effective implementation or dissemination interventions, targeting the adoption of school-based tobacco prevention programs. A systematic search was conducted to identify published systematic reviews that examined the effectiveness of implementation and dissemination strategies for facilitating the adoption of tobacco policies or programs in schools from 1992 to 2012. The search yielded 1028 results, with one relevant systematic review being identified. The review included two controlled studies examining the implementation and dissemination of tobacco prevention programs and guidelines. The two randomised trials examined the delivery of active face-to-face training to implement a school-based curriculum compared with video-delivered or mail-based training. Improvements in the implementation of the programs were reported for the face-to-face training arm in both trials. Little rigorous evidence exists to guide the implementation and dissemination of tobacco prevention programs in schools. SO WHAT? Few systematic reviews exist to inform the implementation of evidence-based tobacco prevention programs in schools. In the absence of a strong evidence base, health care policymakers and practitioners may need to draw on setting-based frameworks or parallel evidence from other settings to design strategies to facilitate the adoption of tobacco prevention initiatives.
Effects of the cyberbullying prevention program media heroes (Medienhelden) on traditional bullying.
Chaux, Enrique; Velásquez, Ana María; Schultze-Krumbholz, Anja; Scheithauer, Herbert

There is considerable debate over whether cyberbullying is just another form of bullying, or whether it is a problem distinct enough to require specific intervention. One way to explore this issue is to analyze whether programs designed to prevent traditional bullying help prevent cyberbullying, and whether programs designed to prevent cyberbullying prevent traditional bullying. The main goal of the current study was to analyze the spillover effects of the cyberbullying prevention program Media Heroes (Medienhelden) on traditional bullying. Media Heroes promotes empathy, knowledge of risks and consequences, and strategies that allow bystanders to defend victims from cyberbullying. Mixed ANOVAs were conducted comparing pretest and post-test (6 months after intervention) measures of 722 students (ages 11-17) assigned to a long (15 sessions) intervention, a short (1 day) intervention, and a control group. In addition to confirming the previously reported effects on cyberbullying, Media Heroes was found to reduce traditional bullying. Effects were larger for the long-version of the program than for the short 1-day version. No effects were found on victimization by either cyberbullying or traditional bullying. Strategies to complement traditional and cyberbullying prevention efforts are discussed. Aggr. Behav. 42:157-165, 2016. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The study's objectives were to: 1) use social support theory to examine factors influencing healthcare workers' opinions about workplace violence (WPV) prevention strategies, and 2) to determine the types of support that general practitioners (GPs) and general nurses sought and expected to use after WPV exposure. A cross-sectional survey was used to assess a sample of 448 GPs and 412 general nurses from 90 township hospitals located in Heilongjiang province, China. Results revealed that workers exposed to physical, psychological or both WPV types had a strong opinion about the necessity of improving diagnosis/treatment competence, developing violence prevention guidelines and plans, using protective equipment, and reinforcing staff by providing back-up support. The last two strategies were also selected by tertiary hospital workers in our previous study. In addition, workers with high anxiety selected the following prevention strategies as most effective: improving doctor-patient communication skills; installing cameras on wards; keeping work areas bright; improvements in violence reporting, statistics, and interventions; security patrols in the key departments; reinforcing staff; and correcting inaccurate media perspectives and reports. The last four strategies were also selected by tertiary hospital workers. All respondents expected to receive organisational and social support. In conclusion, these prevention strategies should be tailored to the different requirements of specific populations. Furthermore, it is necessary for organisations, the public, and policymakers to provide powerful support in WPV prevention.
Therapeutic and prevention strategies against human enterovirus 71 infection
Kok, Chee Choy
2015-01-01
Human enterovirus 71 (HEV71) is the cause of hand, foot and mouth disease and associated neurological complications in children under five years of age. There has been an increase in HEV71 epidemic activity throughout the Asia-Pacific region in the past decade, and it is predicted to replace poliovirus as the extant neurotropic enterovirus of highest global public health significance. To date there is no effective antiviral treatment and no vaccine is available to prevent HEV71 infection. The increase in prevalence, virulence and geographic spread of HEV71 infection over the past decade provides increasing incentive for the development of new therapeutic and prevention strategies against this emerging viral infection. The current review focuses on the potential, advantages and disadvantages of these strategies. Since the explosion of outbreaks leading to large epidemics in China, research in natural therapeutic products has identified several groups of compounds with anti-HEV71 activities. Concurrently, the search for effective synthetic antivirals has produced promising results. Other therapeutic strategies including immunotherapy and the use of oligonucleotides have also been explored. A sound prevention strategy is crucial in order to control the spread of HEV71. To this end the ultimate goal is the rapid development, regulatory approval and widespread implementation of a safe and effective vaccine. The various forms of HEV71 vaccine designs are highlighted in this review. Given the rapid progress of research in this area, eradication of the virus is likely to be achieved. PMID:25964873

Following universal access to antiretroviral therapy in Thailand, evidence from National AIDS Spending Assessment indicates a decreasing proportion of expenditure on prevention interventions. To prompt policymakers to revitalize HIV prevention, this study identifies a comprehensive list of HIV/AIDs preventive interventions that are likely to be effective and cost-effective in Thailand. A systematic review of the national and international literature on HIV prevention strategies from 1997 to 2008 was undertaken. The outcomes used to consider the effectiveness of HIV prevention interventions were changes in HIV risk behaviour and HIV incidence. Economic evaluations that presented their results in terms of cost per HIV infection averted or cost per quality-adjusted life year (QALY) gained were also included. All studies were assessed against quality criteria. The findings demonstrated that school based-sex education plus life-skill programs, voluntary and routine HIV counselling and testing, male condoms, street outreach programs, needle and syringe programs, programs for the prevention of mother-to-child HIV transmission, male circumcision, screening blood products and donated organs for HIV, and increased alcohol tax were all effective in reducing HIV infection among target populations in a cost-effective manner. We found very limited local evidence regarding the effectiveness of HIV interventions amongst specific high risk populations. This underlines the urgent need to prioritise health research resources to assess the effectiveness and cost-effectiveness of HIV interventions aimed at reducing HIV infection among high risk groups in Thailand.

In studies of the mere exposure effect, rapid presentation of items can increase liking without accurate recognition. The effect on liking has been explained as a misattribution of fluency caused by prior presentation. However, fluency is also a source of feelings of familiarity. It is, therefore, surprising that prior experience can enhance liking without also causing familiarity-based recognition. We suggest that when study opportunities are minimal and test items are perceptually similar, people adopt an analytic approach, attempting to recognize distinctive features. That strategy fails because rapid presentation prevents effective encoding of such features; it also prevents people from experiencing fluency and a consequent feeling of familiarity. We suggest that the liking-without-recognition effect results from using an effective (nonanalytic) strategy in judging pleasantness, but an ineffective (analytic) strategy in recognition. Explanations of the mere exposure effect based on a distinction between implicit and explicit memory are unnecessary.
Relapse prevention after index electroconvulsive therapy in treatment-resistant depression
Youssef, Nagy A.; McCall, W. Vaughn
2015-01-01
Background One-third of patients who suffer from depression are resistant to conventional treatments. An acute course of electroconvulsive therapy (ECT) can lead to remission of depressive symptoms in a substantial portion of the treatment-resistant patients. However, prevention of relapse with depressive symptoms after the index course of ECT can be challenging. We review pertinent studies on the topic and analyze the best strategies to avoid relapse and recurrence of depressive symptoms. Methods We performed a systematic literature review of PubMed through April 2014 for clinical trials published in English to determine if continuation ECT, continuation medication, continuation psychotherapy, or combinations of these are the best strategy to avoid relapse and recurrence of depressive symptoms after an acute course of ECT. Clinical trials comparing ≥2 of the above strategies were included in the review. Results Although there are few rigorous randomized clinical trials in this area, most studies suggest that combined continuation ECT (C-ECT) and continuation pharmacotherapy are the most effective strategy in relapse prevention. Conclusions C-ECT and continuation pharmacotherapy may be more effective than either alone for preventing relapse. However, more definitive randomized clinical trials are needed. PMID:25401716

Many countries are developing suicide prevention strategies for which up-to-date, high-quality evidence is required. We present updated evidence for the effectiveness of suicide prevention interventions since 2005. We searched PubMed and the Cochrane Library using multiple terms related to suicide prevention for studies published between Jan 1, 2005, and Dec 31, 2014. We assessed seven interventions: public and physician education, media strategies, screening, restricting access to suicide means, treatments, and internet or hotline support. Data were extracted on primary outcomes of interest, namely suicidal behaviour (suicide, attempt, or ideation), and intermediate or secondary outcomes (treatment-seeking, identification of at-risk individuals, antidepressant prescription or use rates, or referrals). 18 suicide prevention experts from 13 European countries reviewed all articles and rated the strength of evidence using the Oxford criteria. Because the heterogeneity of populations and methodology did not permit formal meta-analysis, we present a narrative analysis. We identified 1797 studies, including 23 systematic reviews, 12 meta-analyses, 40 randomised controlled trials (RCTs), 67 cohort trials, and 22 ecological or population-based investigations. Evidence for restricting access to lethal means in prevention of suicide has strengthened since 2005, especially with regard to control of analgesics (overall decrease of 43% since 2005) and hot-spots for suicide by jumping (reduction of 86% since 2005, 79% to 91%). School-based awareness programmes have been shown to reduce suicide attempts (odds ratio [OR] 0·45, 95% CI 0·24-0·85; p=0·014) and suicidal ideation (0·5, 0·27-0·92; p=0·025). The anti-suicidal effects of clozapine and lithium have been substantiated, but might be less specific than previously thought. Effective pharmacological and psychological treatments of depression are important in prevention. Insufficient evidence exists to assess the possible benefits for suicide prevention of screening in primary care, in general public education and media guidelines. Other approaches that need further investigation include gatekeeper training, education of physicians, and internet and helpline support. The paucity of RCTs is a major limitation in the evaluation of preventive interventions. In the quest for effective suicide prevention initiatives, no single strategy clearly stands above the others. Combinations of evidence-based strategies at the individual level and the population level should be assessed with robust research designs.

Systematic evidence reviews support the efficacy of physical activity programs and multifactorial strategies for fall prevention. However, community settings where fall prevention programs occur often differ substantially from the research settings in which efficacy was first demonstrated. Because of these differences, alternative approaches are needed to judge the adequacy of fall prevention activities occurring as part of standard medical care or community efforts. This paper uses the World Health Organization Innovative Care for Chronic Conditions (ICCC) framework to rethink how fall prevention programs might be implemented routinely in both medical and community settings. We highlight examples of innovative programs and policies that provide fall prevention strategies consistent with the ICCC framework, and provide evidence where available on the effects of these strategies on processes and outcomes of care. We close by proposing a “no wrong door” approach to fall prevention and management, in which older adults who are found to be at risk for falls in either a medical or community setting are linked to a standard fall risk evaluation across three domains (physical activity, medical risks and home safety).

OBJECTIVE We attempted to determine whether multimedia fall prevention education using different instructional strategies increases older adults’ knowledge of fall threats and their fall prevention behaviors. METHOD Fifty-three community-dwelling older adults were randomized to two educational groups or a control group. Multimedia-based educational interventions to increase fall threats knowledge and encourage fall prevention behaviors had two tailoring strategies: (1) improve content realism for individual learners (authenticity group) and (2) highlight program goals and benefits while using participants’ content selections (motivation group). Knowledge was measured at baseline and 1-mo follow-up. Participants recorded prevention behaviors for 1 mo. RESULTS Intervention group participants showed greater knowledge gains and posttest knowledge than did control group participants. The motivation group engaged in more prevention behaviors over 1 mo than did the other groups. CONCLUSION Tailoring fall prevention education by addressing authenticity and motivation successfully improved fall threats knowledge. Combining motivational strategies with multimedia education increased the effectiveness of the intervention in encouraging fall prevention behaviors. PMID:22214115

The past few decades have witnessed an increase in the prevalence of IgE-mediated food allergy (FA). For prevention strategies to be effective, we need to understand the causative factors underpinning this rise. Genetic factors are clearly important in the development of FA, but given the dramatic increase in prevalence over a short period of human evolution, it is unlikely that FA arises through germline genetic changes alone. A plausible hypothesis is that 1 or more environmental exposures, or lack thereof, induce epigenetic changes that result in interruption of the default immunologic state of tolerance. Strategies for the prevention of FA might include primary prevention, which seeks to prevent the onset of IgE sensitization; secondary prevention, which seeks to interrupt the development of FA in IgE-sensitized children; and tertiary prevention, which seeks to reduce the expression of end-organ allergic disease in children with established FA. This review emphasizes the prevention of IgE-mediated FA through dietary manipulation, among other strategies; in particular, we focus on recent interventional studies in this field.

The global burden of breast cancer highlights the need for primary prevention strategies that demonstrate both favorable clinical benefit/risk profile and good value for money. Endocrine therapy with selective estrogen-receptor modulators (SERMs) or aromatase inhibitors (AIs) has been associated with a favorable clinical benefit/risk profile in the prevention of breast cancer in women at high risk of developing the disease. The available endocrine therapy strategies differ in terms of their relative reductions of breast cancer risk, potential side effects, and upfront drug acquisition costs, among others. This review highlights the clinical trials of SERMs and AIs for the primary prevention of breast cancer, and the cost-effectiveness /cost-utility studies that have examined their "value for money" in various health care jurisdictions.

Bovine trichomoniasis has been recognized as a pathogen of the bovine reproductive tract for nearly 100 years. Although characteristics of the causative organism, Tritrichomonas foetus lend to control and there are examples of disease eradication, cattle producers are still faced with this disease. This article highlights the clinical presentation, magnitude of effect, risk factors, epidemiology, and sample collection and suggests applications in developing herd-level control measures for beef cattle producers including testing strategies for control, testing strategies for surveillance, strategies to eliminate trichomoniasis from infected herds, and strategies for prevention in uninfected herds.

2017-01-01
SUMMARY Impairment of varicella zoster virus (VZV)-specific cell-mediated immunity, including impairment due to immunosenescence, is associated with an increased risk of developing herpes zoster (HZ), whereas levels of anti-VZV antibodies do not correlate with HZ risk. This crucial role of VZV-specific cell-mediated immunity suggests that boosting these responses by vaccination will be an effective strategy for reducing the burden of HZ. Other strategies focus on preventing the major complication of HZ – post-herpetic neuralgia. These strategies include pre-emptive treatment with drugs such as tricyclic antidepressants, anticonvulsants and analgesics. PMID:20510262
Translating evidence into policy for cardiovascular disease control in India
2011-01-01
Cardiovascular diseases (CVD) are leading causes of premature mortality in India. Evidence from developed countries shows that mortality from these can be substantially prevented using population-wide and individual-based strategies. Policy initiatives for control of CVD in India have been suggested but evidence of efficacy has emerged only recently. These initiatives can have immediate impact in reducing morbidity and mortality. Of the prevention strategies, primordial involve improvement in socioeconomic status and literacy, adequate healthcare financing and public health insurance, effective national CVD control programme, smoking control policies, legislative control of saturated fats, trans fats, salt and alcohol, and development of facilities for increasing physical activity through better urban planning and school-based and worksite interventions. Primary prevention entails change in medical educational curriculum and improved healthcare delivery for control of CVD risk factors-smoking, hypertension, dyslipidemia and diabetes. Secondary prevention involves creation of facilities and human resources for optimum acute CVD care and secondary prevention. There is need to integrate various policy makers, develop effective policies and modify healthcare systems for effective delivery of CVD preventive care. PMID:21306620

Background. Recurrent urinary tract infections (UTIs) are a common problem among women. However, comparative effectiveness strategies for managing recurrent UTIs are lacking. Methods. We performed a systematic literature review of management of women experiencing ≥3 UTIs per year. We then developed a Markov chain Monte Carlo model of recurrent UTI for each management strategy with ≥2 adequate trials published. We simulated a cohort that experienced 3 UTIs/year and a secondary cohort that experienced 8 UTIs/year. Model outcomes were treatment efficacy, patient and payer cost, and health-related quality of life. Results. Five strategies had ≥2 clinical trials published: (1) daily antibiotic (nitrofurantoin) prophylaxis; (2) daily estrogen prophylaxis; (3) daily cranberry prophylaxis; (4) acupuncture prophylaxis; and (5) symptomatic self-treatment. In the 3 UTIs/year model, nitrofurantoin prophylaxis was most effective, reducing the UTI rate to 0.4 UTIs/year, and the most expensive to the payer ($821/year). All other strategies resulted in payer cost savings but were less efficacious. Symptomatic self-treatment was the only strategy that resulted in patient cost savings, and was the most favorable strategy in term of cost per quality-adjusted life-year (QALY) gained. Conclusions. Daily antibiotic use is the most effective strategy for recurrent UTI prevention compared to daily cranberry pills, daily estrogen therapy, and acupuncture. Cost savings to payers and patients were seen for most regimens, and improvement in QALYs were seen with all. Our findings provide clinically meaningful data to guide the physician–patient partnership in determining a preferred method of prevention for this common clinical problem. PMID:24065333

Whether to cover cardiovascular disease costs is an increasingly pressing question for low- and middle-income countries. We sought to identify the impact of expanding national insurance to cover primary prevention, secondary prevention, and tertiary treatment for cardiovascular disease in India. We incorporated data from coverage experiments into a validated microsimulation model of myocardial infarction and stroke in India to evaluate the cost-effectiveness of alternate coverage strategies. Coverage of primary prevention alone saved 3.6 million disability-adjusted life-years (DALY) per annum at an incremental cost-effectiveness ratio of $469 per DALY averted when compared with the status quo of no coverage. Coverage of primary and secondary preventions was dominated by a strategy of covering primary prevention and tertiary treatment, which prevented 6.6 million DALYs at an incremental cost-effectiveness ratio of $2241 per DALY averted, when compared with that of primary prevention alone. The combination of all 3 categories yielded the greatest impact at an incremental cost per DALY averted of $5588 when compared with coverage of primary prevention plus tertiary treatment. When compared with the status quo of no coverage, coverage of all 3 categories of prevention/treatment yielded an incremental cost-effectiveness ratio of $1331 per DALY averted. In sensitivity analyses, coverage of primary preventive treatments remained cost-effective even if adherence and access to therapy were low, but tertiary coverage would require avoiding unnecessary procedures to remain cost-effective. Coverage of all 3 major types of cardiovascular treatment would be expected to have high impact and reasonable cost-effectiveness in India across a broad spectrum of access and adherence levels. © 2015 American Heart Association, Inc.

Childhood obesity is a major concern for public health. There are multiple factors (e.g., genetic, social, and environmental) that contribute to unhealthy weight gain. Drawing from findings on "obesogenic environments" and core principles of preventive strategies to reduce health inequalities, this paper gives an overview of recent childhood prevention programs that target aspects of the physical environment ("environmental changes"). Out of the ten reviews we screened (including more than 300 studies), we identified very few that addressed aspects of the environment. We focus here on 14 programs that follow different approaches to environmental changes (e.g., access to/quality of playgrounds, changes in school cafeterias). Altering the environment offers opportunities for healthier behaviors and seems to be an effective strategy to prevent childhood obesity. However, the evaluation of those (mostly) multidimensional interventions does not allow drawing firm conclusions about the single effect of environmental changes. We conclude that obesity prevention programs should combine person-based and environmental approaches.

Although the college years prove to be a vulnerable time for students and a critical period for suicide prevention, few school-based prevention strategies have been empirically evaluated. The current study examined the short-term effects of Question, Persuade, and Refer (QPR), a gatekeeper training program that teaches how to recognize warning…
Update on infection control challenges in special pediatric populations.
Balkhy, Hanan H; Zingg, Walter
2014-08-01
Compared with adults, neonatal and pediatric populations are especially vulnerable patients who have specific diagnostic and therapeutic differences; therefore, the standard infection control practices designed for adults are sometimes not effective or need modifications to work. This review focuses on the recent literature addressing the challenges and successes in preventing healthcare-associated infections (HAIs) in children. Improving the implementation of pediatric versions of preventive bundles focusing on proper catheter insertion and maintenance, mainly as a part of a larger multimodal strategy, is effective in reducing the central-line-associated bloodstream infections in neonatal and pediatric populations including oncology patients. Appropriate feeding, antimicrobial stewardship, and infection control measures should be combined in reducing necrotizing enterocolitis in preterm neonates. Implementing a multimodal bundle strategy adapted for pediatric population is successful in preventing ventilator-associated pneumonia. Appropriate use of antimicrobial prophylaxis remains the cornerstone for preventing surgical-site infections irrespective of age, with few additional effective adjuvant preventive practices in specific pediatric patients. Several evidence-based practices are effective in reducing the incidence and the impact of HAIs in children; however, proper implementation remains a challenge. Additionally, several adult preventive practices are still unestablished in children and need further thorough examination.
Use of health economics in the development of a national radon control strategy in Ireland.
Pollard, D; Fenton, D
2014-07-01
A health economics evaluation of different radon intervention strategies was undertaken including the incorporation of prevention into new buildings, the incorporation of potential remedial measures into new buildings and remediation of existing buildings. The analysis shows that (1) the incorporation of prevention into new houses at the time of construction is generally more cost effective than remediation of existing houses and (2) that the cost effectiveness of programmes aimed at encouraging householders to test and remediate their houses may be poor if they are not undertaken within the context of coherent radon reduction strategy. The results of this evaluation were used to identify the most cost-effective radon interventions in an Irish context in support of the development of a National Radon Control Strategy. © The Author 2014.

It is no surprise to educators and prevention specialists that for more than two decades, the majority of evaluation studies of individual psychosocial prevention strategies not only in substance-abuse prevention but in all of social science research have failed to find sustained positive outcomes (Feldman, 1983; Kreft & Brown, 1998).

The effectiveness of oral hydration in preventing contrast-induced acute kidney injury (CI-AKI) in patients undergoing coronary angiography or intervention has not been well established. This study aims to evaluate the efficacy of oral hydration compared with intravenous hydration and other frequently used hydration strategies. PubMed, Embase, Web of Science, and the Cochrane central register of controlled trials were searched from inception to 8 October 2017. To be eligible for analysis, studies had to evaluate the relative efficacy of different prophylactic hydration strategies. We selected and assessed the studies that fulfilled the inclusion criteria and carried out a pairwise and network meta-analysis using RevMan5.2 and Aggregate Data Drug Information System 1.16.8 software. A total of four studies (538 participants) were included in our pairwise meta-analysis and 1754 participants from eight studies with four frequently used hydration strategies were included in a network meta-analysis. Pairwise meta-analysis indicated that oral hydration was as effective as intravenous hydration for the prevention of CI-AKI (5.88 vs. 8.43%; odds ratio: 0.73; 95% confidence interval: 0.36-1.47; P>0.05), with no significant heterogeneity between studies. Network meta-analysis showed that there was no significant difference in the prevention of CI-AKI. However, the rank probability plot suggested that oral plus intravenous hydration had a higher probability (51%) of being the best strategy, followed by diuretic plus intravenous hydration (39%) and oral hydration alone (10%). Intravenous hydration alone was the strategy with the highest probability (70%) of being the worst hydration strategy. Our study shows that oral hydration is not inferior to intravenous hydration for the prevention of CI-AKI in patients with normal or mild-to-moderate renal dysfunction undergoing coronary angiography or intervention.

Over the last decade, there has been a growing appreciation of the importance of identifying and treating cognitive impairment associated with bipolar disorder, since it persists in remission periods. Evidence indicates that neurocognitive dysfunction may significantly influence patients' psychosocial outcomes. An ever-increasing body of research seeks to achieve a better understanding of potential moderators contributing to cognitive impairment in bipolar disorder in order to develop prevention strategies and effective treatments. This review provides an overview of the available data from studies examining treatments for cognitive dysfunction in bipolar disorder as well as potential novel treatments, from both pharmacological and psychological perspectives. All these data encourage the development of further studies to find effective strategies to prevent and treat cognitive impairment associated with bipolar disorder. These efforts may ultimately lead to an improvement of psychosocial functioning in these patients. © The Author 2017. Published by Oxford University Press on behalf of CINP.

There is increasing evidence that exercise is an effective strategy for the prevention and treatment of osteoporosis. The randomized controlled trials and their meta-analyses to date, evaluating the effects of exercise on osteoporosis reveal that the exercise is effective in preserving bone mass, preventing fractures and falls, and improving quality of life in patients with osteoporosis. Emphasis is also given to the importance of the specific protocols of exercises needed to achieve positive effects safely, keeping in view the age and general physical condition of the person.
Inoculation effect in prevention of increased verbal aggression in schools.
Rosenberg, Steven
2004-12-01
This paper presents an argument for the use of intervention programs as inoculation agents in adolescents' social behavior, specifically the prevention of abusive and antisocial verbal aggression. The theoretical substance of the intervention is social-cognitive and eclectic, borrowing from several strategies known to be effective. The bridge between theory and curriculum is an inoculation-like process. Inoculation is not a strategy to change beliefs but rather to reinforce prosocial attitudes and assist students in overcoming influences that might lessen their prosocial stance. Results must include a control group to assess the effect of inoculation.
Tools for Identifying and Prioritizing Evidence-Based Obesity Prevention Strategies, Colorado
Juhl, Ashley L.; Gujral, Indira B.; Hoaglin-Wagner, Andrea L.; Gabella, Barbara A.; McDermott, Kristin M.

Colorado’s adult obesity rate has more than doubled since 1995, prompting its Department of Public Health and Environment to list obesity as its top prevention priority. To initiate comprehensive and effective action, the department used a well-known evidence-based public health framework developed by Brownson and others. This article describes the tools and process developed to conduct 2 of the 7 stages in this framework that challenge public health organizations: reviewing the literature and prioritizing effective strategies from that literature. Forty-five department staff participated in an intensive literature review training to identify physical activity and nutrition strategies that effectively address obesity and worked with external stakeholders to prioritize strategies for the state. Divided into 8 multidisciplinary teams organized by the setting where public health could exert leverage, they scanned the scientific literature to identify potential strategies to implement. These teams were trained to use standardized tools to critique findings, systematically abstract key information, and classify the evidence level for each of 58 identified strategies. Next, departmental subject matter experts and representatives from local public health and nonprofit health agencies selected and applied prioritization criteria to rank the 58 strategies. A team charter, group facilitation tools, and 2 web-based surveys were used in the prioritization stage. This process offered the staff a shared experience to gain hands-on practice completing literature reviews and selecting evidence-based strategies, thereby enhancing Colorado’s obesity prevention efforts and improving public health capacity. Practitioners can use these tools and methodology to replicate this process for other health priorities. PMID:23806801
Global climate change and children's health: threats and strategies for prevention.
Sheffield, Perry E; Landrigan, Philip J
2011-03-01
Global climate change will have multiple effects on human health. Vulnerable populations-children, the elderly, and the poor-will be disproportionately affected. We reviewed projected impacts of climate change on children's health, the pathways involved in these effects, and prevention strategies. We assessed primary studies, review articles, and organizational reports. Climate change is increasing the global burden of disease and in the year 2000 was responsible for > 150,000 deaths worldwide. Of this disease burden, 88% fell upon children. Documented health effects include changing ranges of vector-borne diseases such as malaria and dengue; increased diarrheal and respiratory disease; increased morbidity and mortality from extreme weather; changed exposures to toxic chemicals; worsened poverty; food and physical insecurity; and threats to human habitation. Heat-related health effects for which research is emerging include diminished school performance, increased rates of pregnancy complications, and renal effects. Stark variation in these outcomes is evident by geographic region and socioeconomic status, and these impacts will exacerbate health disparities. Prevention strategies to reduce health impacts of climate change include reduction of greenhouse gas emissions and adaptation through multiple public health interventions. Further quantification of the effects of climate change on children's health is needed globally and also at regional and local levels through enhanced monitoring of children's environmental health and by tracking selected indicators. Climate change preparedness strategies need to be incorporated into public health programs.

To address increases in the incidence of infection with antimicrobial-resistant pathogens, the National Foundation for Infectious Diseases and Centers for Disease Control and Prevention proposed two sets of strategies to (a) optimize antibiotic use and (b) prevent the spread of antimicrobial resistance and control transmission. However, little is known about the implementation of these strategies. Our objective is to explore organizational structural and process factors that facilitate the implementation of National Foundation for Infectious Diseases/Centers for Disease Control and Prevention strategies in U.S. hospitals. We surveyed 448 infection control professionals from a national sample of hospitals. Clinically anchored in the Donabedian model that defines quality in terms of structural and process factors, with the structural domain further informed by a contingency approach, we modeled the degree to which National Foundation for Infectious Diseases and Centers for Disease Control and Prevention strategies were implemented as a function of formalization and standardization of protocols, centralization of decision-making hierarchy, information technology capabilities, culture, communication mechanisms, and interdepartmental coordination, controlling for hospital characteristics. Formalization, standardization, centralization, institutional culture, provider-management communication, and information technology use were associated with optimal antibiotic use and enhanced implementation of strategies that prevent and control antimicrobial resistance spread (all p < .001). However, interdepartmental coordination for patient care was inversely related with antibiotic use in contrast to antimicrobial resistance spread prevention and control (p < .0001). Formalization and standardization may eliminate staff role conflict, whereas centralized authority may minimize ambiguity. Culture and communication likely promote internal trust, whereas information technology use helps integrate and support these organizational processes. These findings suggest concrete strategies for evaluating current capabilities to implement effective practices and foster and sustain a culture of patient safety.
Strategies and Challenges in Preventing Violence Against Canadian Indoor Sex Workers

Objectives. To examine indoor sex workers’ strategies in preventing workplace violence and influential socio-structural conditions. Methods. Data included qualitative interviews with 85 sex workers in British Columbia, Canada, from 2014 through 2016. For analyses, we used interpretive thematic techniques informed by World Health Organization position statements on violence. Results. Robbery, nonpayment, financial exploitation, and privacy violations were frequent types of violence perpetrated by clients, landlords, and neighbors. We identified 2 themes that depicted how sex workers prevented violence and mitigated its effects: (1) navigating physical spaces and (2) navigating client relationships. Conclusions. Sex workers’ diverse strategies to prevent violence and mitigate its effects are creative and effective in many circumstances. These are limited, however, by the absence of legal and public health regulations governing occupational health and safety and stigma associated with sex work. Public Health Implications. Occupational health and safety regulatory policies that set conditions for clients’ substance and condom use within commercial sex transactions are required. Revisions to the current legal regulations governing prostitution are critical to support optimal work environments that reduce the likelihood of violence. These revisions must recognize sex work as a form of labor versus victimization. PMID:29346001

Background A number of treatments have been shown to reduce the risk of postoperative recurrence of Crohn's disease (CD). The optimal strategy is unknown. The aim was to evaluate the comparative cost-effectiveness of postoperative strategies to prevent clinical recurrence of CD. Methods Three prophylactic strategies were compared to “no prophylaxis”; mesalamine, azathioprine (AZA) / 6-mercaptopurine (6-MP), and infliximab. The probability of clinical recurrence, endoscopic recurrence, and therapy discontinuation due to adverse drug reactions (ADRs) were extracted from randomized controlled trials (RCTs). Quality-of-life scores and treatment costs were derived from published data. The primary model evaluated quality-adjusted life years (QALYs) and cost-effectiveness at 1 year after surgery. Sensitivity analysis assessed the impact of a range of recurrence rates on cost-effectiveness. An exploratory analysis evaluated cost-effectiveness outcomes 5 years after surgery. Results A strategy of “no prophylaxis” was the least expensive one at 1 and 5 years after surgery. Compared to this approach, AZA/6-MP had the most favorable incremental cost-effectiveness ratio (ICER) ($299,188/QALY gained), and yielded the highest net health benefits of the medication strategies at 1 year. Sensitivity analysis determined that the ICER of AZA/6-MP was preferable to mesalamine up to a recurrence rate of 52%, but mesalamine dominated at higher rates. In the 5-year exploratory analysis, mesalamine had the most favorable ICER over 5 years ($244,177/QALY gained). Conclusions Compared to no prophylactic treatment, AZA/6-MP has the most favorable ICER in the prevention of clinical recurrence of postoperative CD up to 1 year. At 5 years, mesalamine had the most favorable ICER in this model. PMID:21905173

A recent large-scale randomized controlled trial (RCT) demonstrated that rectal indomethacin administration is effective in addition to pancreatic stent placement (PSP) for preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) in high-risk cases. We performed a post hoc analysis of this RCT to explore whether rectal indomethacin can replace PSP in the prevention of PEP and to estimate the potential cost savings of such an approach. We retrospectively classified RCT subjects into four prevention groups: (1) no prophylaxis, (2) PSP alone, (3) rectal indomethacin alone, and (4) the combination of PSP and indomethacin. Multivariable logistic regression was used to adjust for imbalances in the prevalence of risk factors for PEP between the groups. Based on these adjusted PEP rates, we conducted an economic analysis comparing the costs associated with PEP prevention strategies employing rectal indomethacin alone, PSP alone, or the combination of both. After adjusting for risk using two different logistic regression models, rectal indomethacin alone appeared to be more effective for preventing PEP than no prophylaxis, PSP alone, and the combination of indomethacin and PSP. Economic analysis revealed that indomethacin alone was a cost-saving strategy in 96% of Monte Carlo trials. A prevention strategy employing rectal indomethacin alone could save approximately $150 million annually in the United States compared with a strategy of PSP alone, and $85 million compared with a strategy of indomethacin and PSP. This hypothesis-generating study suggests that prophylactic rectal indomethacin could replace PSP in patients undergoing high-risk ERCP, potentially improving clinical outcomes and reducing healthcare costs. A RCT comparing rectal indomethacin alone vs. indomethacin plus PSP is needed.

Diabetes mellitus is a public health challenge worldwide, and roughly 25% of patients with diabetes in developing countries will develop at least one foot ulcer during their lifetime. The gravest outcome of an ulcerated foot is amputation, leading to premature death and larger economic costs. This study aimed to estimate the economic costs of diabetic foot in high-risk patients in Peru in 2012 and to model the cost-effectiveness of a year-long preventive strategy for foot ulceration including: sub-optimal care (baseline), standard care as recommended by the International Diabetes Federation, and standard care plus daily self-monitoring of foot temperature. A decision tree model using a population prevalence-based approach was used to calculate the costs and the incremental cost-effectiveness ratio (ICER). Outcome measures were deaths and major amputations, uncertainty was tested with a one-way sensitivity analysis. The direct costs for prevention and management with sub-optimal care for high-risk diabetics is around US$74.5 million dollars in a single year, which decreases to US$71.8 million for standard care and increases to US$96.8 million for standard care plus temperature monitoring. The implementation of a standard care strategy would avert 791 deaths and is cost-saving in comparison to sub-optimal care. For standard care plus temperature monitoring compared to sub-optimal care the ICER rises to US$16,124 per death averted and averts 1,385 deaths. Diabetic foot complications are highly costly and largely preventable in Peru. The implementation of a standard care strategy would lead to net savings and avert deaths over a one-year period. More intensive prevention strategies such as incorporating temperature monitoring may also be cost-effective.

Vaccination is an effective strategy to prevent and control the transmission of hepatitis A. Hepatitis A immunization program has been taken into effect since 2001 in Tianjin, China. This study evaluated the effectiveness of strategies in the prevention and control of hepatitis A. Data of serological survey, annual hepatitis A incidence, immunization coverage and the positive rate of hepatitis A IgG before and after the immunization program in residents under 15 years old were used to do the analysis. The results indicated that hepatitis A vaccine induced a striking decrease of hepatitis A incidence and a significant increase in the positive rate of anti-HAV IgG among the children younger than 15 years old. Hepatitis A vaccination in children was proved to be effective in the prevention and control of hepatitis A in Tianjin, China. PMID:24503599

Preventing neural tube defects (NTDs) easily qualifies as a high-value opportunity to improve childhood survival and health: the unmet need is significant (major preventable burden), the intervention is transformative (providing sufficient folic acid), and delivery strategies (e.g., fortification) are effective in low-resource countries. Yet, NTD prevention is lagging. Can public health surveillance help fix this problem? Critics contend that surveillance is largely unnecessary, that limited resources are best spent on interventions, and that surveillance is unrealistic in developing countries. The counterargument is twofold: (1) in the absence of surveillance, interventions will provide fewer benefits and cost more and (2) effective surveillance is likely possible nearly everywhere, with appropriate strategies. As a base strategy, we propose "triple surveillance:" integrating surveillance of cause (folate insufficiency), of disease occurrence (NTD prevalence), and of health outcomes (morbidity, mortality, and disability). For better sustainability and usefulness, it is crucial to refocus and streamline surveillance activities (no recreational data collection), weave surveillance into clinical care (integrate in clinical workflow), and, later, work on including additional risk factors and pediatric outcomes (increase benefits at low marginal cost). By doing so, surveillance becomes not a roadblock but a preferential path to prevention and better care. © 2018 The Authors.

Uncertainties continue regarding effective strategies to prevent and address the consequences of gender-based violence (GBV) among refugees. The databases of PubMed, Cochrane Library, Scopus, PsycINFO, Web of Science, Anthropology Plus, EMBASE, DARE, Google Scholar, MSF Field Research, UNHCR and the regional and global indices of the WHO Global Health Library were searched twice within a 6-month period (April and September 2011) for English-language clinical, public health, basic and social science studies evaluating strategies to prevent and manage health sequelae of GBV among refugees before September 2011. Studies not primarily about prevention and treatment, and not describing population, health outcome and interventions, were excluded. The literature search for the prevention and management arms produced 1212 and 1106 results, respectively. After reviewing the titles and abstracts, 29 and 27 articles were selected for review in their entirety, none of which met the inclusion criteria. Multiple panels of expert recommendations and guidelines were not supported by primary data on actual displaced populations. There is a dire need for research that evaluates the efficacy and effectiveness of various responses to GBV to ultimately allow a transition from largely theoretical and expertise driven to a more evidence-based field. We recommend strategies to improve data collection and to overcome barriers in primary data driven research.

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has emerged as an important cause of healthcare-associated infection. CA-MRSA clones have replaced classic hospital MRSA clones in many countries and have shown higher potential in transmission and virulence than hospital MRSA clones. In particular, the emergence of CA-MRSA in the Asia-Pacific region is concerning owing to insufficient infection control measures in the region. The old strategies for infection prevention and control of MRSA comprised adherence to standard precaution and policy of active screening of MRSA carriers and decolonization, and it has been controversial which strategy is better in terms of outcome and cost-effectiveness. Epidemiological changes in MRSA has made the development of infection prevention strategy more complicated. Based on the literature review and the questionnaire survey, we considered infection prevention strategies for healthcare settings in the Asia-Pacific region in the era of CA-MRSA. © The Author 2017.

Introduction Residents of rural communities in the United States are at higher risk for obesity than their urban and suburban counterparts. Policy and environmental-change strategies supporting healthier dietary intake can prevent obesity and promote health equity. Evidence in support of these strategies is based largely on urban and suburban studies; little is known about use of these strategies in rural communities. The purpose of this review was to synthesize available evidence on the adaptation, implementation, and effectiveness of policy and environmental obesity-prevention strategies in rural settings. Methods The review was guided by a list of Centers for Disease Control and Prevention Recommended Community Strategies and Measurements to Prevent Obesity in the United States, commonly known as the “COCOMO” strategies. We searched PubMed, Cumulative Index of Nursing and Allied Health Literature, Public Affairs Information Service, and Cochrane databases for articles published from 2002 through 2013 that reported findings from research on nutrition-related policy and environmental strategies in rural communities in the United States and Canada. Two researchers independently abstracted data from each article, and resolved discrepancies by consensus. Results Of the 663 articles retrieved, 33 met inclusion criteria. The interventions most commonly focused on increasing access to more nutritious foods and beverages or decreasing access to less nutritious options. Rural adaptations included accommodating distance to food sources, tailoring to local food cultures, and building community partnerships. Conclusions Findings from this literature review provide guidance on adapting and implementing policy and environmental strategies in rural communities. PMID:25927605
Refusal skill ability: an examination of adolescent perceptions of effectiveness.
Nichols, Tracy R; Birnel, Sara; Graber, Julia A; Brooks-Gunn, Jeanne; Botvin, Gilbert J
2010-06-01
This pilot study examined whether refusal assertion as defined by a proven drug prevention program was associated with adolescent perceptions of effectiveness by comparing two sets of coded responses to adolescent videotaped refusal role-plays (N = 63). The original set of codes was defined by programmatic standards of refusal assertion and the second by a group of high school interns. Consistency with programming criteria was found for interns' ratings of several indicators of verbal and non-verbal assertiveness. However, a strategy previously defined by the program as effective was perceived as ineffective by adolescents while another deemed ineffective and problematic by intervention developers was viewed as effective. Interns endorsed presenting detailed and reasonable arguments as an effective refusal strategy while short, simple statements were deemed ineffective. This study suggests the importance of including adolescent perspectives in the design, delivery, and evaluation of drug prevention strategies.

The study’s objectives were to: 1) use social support theory to examine factors influencing healthcare workers’ opinions about workplace violence (WPV) prevention strategies, and 2) to determine the types of support that general practitioners (GPs) and general nurses sought and expected to use after WPV exposure. A cross-sectional survey was used to assess a sample of 448 GPs and 412 general nurses from 90 township hospitals located in Heilongjiang province, China. Results revealed that workers exposed to physical, psychological or both WPV types had a strong opinion about the necessity of improving diagnosis/treatment competence, developing violence prevention guidelines and plans, using protective equipment, and reinforcing staff by providing back-up support. The last two strategies were also selected by tertiary hospital workers in our previous study. In addition, workers with high anxiety selected the following prevention strategies as most effective: improving doctor-patient communication skills; installing cameras on wards; keeping work areas bright; improvements in violence reporting, statistics, and interventions; security patrols in the key departments; reinforcing staff; and correcting inaccurate media perspectives and reports. The last four strategies were also selected by tertiary hospital workers. All respondents expected to receive organisational and social support. In conclusion, these prevention strategies should be tailored to the different requirements of specific populations. Furthermore, it is necessary for organisations, the public, and policymakers to provide powerful support in WPV prevention. PMID:27326460
[Alcohol and drugs in Central Europe--problems and possible solutions].
Nespor, K; Cs emy, L

The high alcohol consumption and increasing abuse of other addictive inducing substances in Central Europe calls for broadley conceived preventive programmes and cheap and widely applicable therapeutic strategies (early treatment at the first contact level, self-help manuals, self-aid organizations). Social instability along with greater availability of alcohol and drugs create a dangerous combination. In addition to strategies of stress prevention at the societal level also strategy at the individual level is important (e.g. relaxation training, yoga, psychotherapy). It is also important to change the "image" of western society and commercial interests of those who make profits on alcohol and drugs should be under control and advertising should be greatly restricted if not prohibited. Prevention of problems caused by alcohol and drugs in particular in youths must be combined and really effective strategies should be used such as peer programmes. The authors mention also their own preventive programme FIT IN and print materials oriented specifically on certain population groups.
Estimating costs of sea lice control strategy in Norway.
Liu, Yajie; Bjelland, Hans Vanhauwaer
2014-12-01
This paper explores the costs of sea lice control strategies associated with salmon aquaculture at a farm level in Norway. Diseases can cause reduction in growth, low feed efficiency and market prices, increasing mortality rates, and expenditures on prevention and treatment measures. Aquaculture farms suffer the most direct and immediate economic losses from diseases. The goal of a control strategy is to minimize the total disease costs, including biological losses, and treatment costs while to maximize overall profit. Prevention and control strategies are required to eliminate or minimize the disease, while cost-effective disease control strategies at the fish farm level are designed to reduce the losses, and to enhance productivity and profitability. Thus, the goal can be achieved by integrating models of fish growth, sea lice dynamics and economic factors. A production function is first constructed to incorporate the effects of sea lice on production at a farm level, followed by a detailed cost analysis of several prevention and treatment strategies associated with sea lice in Norway. The results reveal that treatments are costly and treatment costs are very sensitive to treatment types used and timing of the treatment conducted. Applying treatment at an early growth stage is more economical than at a later stage. Copyright © 2014 Elsevier B.V. All rights reserved.

The goals of this article are to: 1) provide descriptive data about the prevalence and the severity of lower back and upper back disorders in EMTs and paramedics; 2) identify some individual and collective strategies used by EMTs and paramedics to protect their health as they perform prehospital emergency missions; 3) assess the possible effectiveness of strategies in preventing back problems by exploring associations between the use of strategies and the presence and severity of symptoms. The method includes a questionnaire survey (sample n = 334; paramedics and emergency medical technicians) and ergonomics work practice analysis involving shadowing ambulance crews in 12 medical emergency services (over 400 h). A majority of ambulance professionals had experienced back pain in the twelve-month period before the survey. Work practice analysis revealed strategies and tricks of the trade used by ambulance professionals to reduce the chances of back strain while working. Multiple regression analyses showed that self-reported use of such strategies was associated with fewer back symptoms. Preventive strategies should be integrated into specialised training programs for prehospital medical emergency professionals. This approach could also be used in other work settings.

We developed a Markov microsimulation model among hypothetical cohorts of community-dwelling US white women without prior major osteoporotic fractures over a lifetime horizon. At ages 75 and 80, adding 1 year of exercise to 5 years of oral bisphosphonate therapy is cost-effective at a conventionally accepted threshold compared with bisphosphonates alone. The purpose of this study was to examine the cost-effectiveness of the combined strategy of oral bisphosphonate therapy for 5 years and falls prevention exercise for 1 year compared with either strategy in isolation. We calculated incremental cost-effectiveness ratios [ICERs] (2014 US dollars per quality-adjusted life year [QALY]), using a Markov microsimulation model among hypothetical cohorts of community-dwelling US white women with different starting ages (65, 70, 75, and 80) without prior history of hip, vertebral, or wrist fractures over a lifetime horizon from the societal perspective. At ages 65, 70, 75, and 80, the combined strategy had ICERs of $202,020, $118,460, $46,870, and $17,640 per QALY, respectively, compared with oral bisphosphonate therapy alone. The combined strategy provided better health at lower cost than falls prevention exercise alone at ages 70, 75, and 80. In deterministic sensitivity analyses, results were particularly sensitive to the change in the opportunity cost of participants' time spent exercising. In probabilistic sensitivity analyses, the probabilities of the combined strategy being cost-effective compared with the next best alternative increased with age, ranging from 35 % at age 65 to 48 % at age 80 at a willingness-to-pay of $100,000 per QALY. Among community-dwelling US white women ages 75 and 80, adding 1 year of exercise to 5 years of oral bisphosphonate therapy is cost-effective at a willingness-to-pay of $100,000 per QALY, compared with oral bisphosphonate therapy only. This analysis will help clinicians and policymakers make better decisions about treatment options to reduce fracture risk.

Both intimate partner violence (IPV) and community violence are prevalent globally, and each is associated with serious health consequences. However, little is known about their potential links or the possible benefits of coordinated prevention strategies. Using aggregated data on community violence from the São Paulo State Security Department (INFOCRIM) merged with WHO multi-country study on women's health and domestic violence data, random intercept models were created to assess the effect of crime on women's probability of experiencing IPV. The association between IPV and male aggression (measured by women's reports of their partner's fights with other men) was examined using logistic regression models. We found little variation in the likelihood of male IPV perpetration related to neighborhood crime level but did find an increased likelihood of IPV experiences among women whose partners were involved in male-to-male violence. Emerging evidence on violence prevention has suggested some promising avenues for primary prevention that address common risk factors for both perpetration of IPV and male interpersonal violence. Strategies such as early identification and effective treatment of emotional disorders, alcohol abuse prevention and treatment, complex community-based interventions to change gender social norms and social marketing campaigns designed to modify social and cultural norms that support violence may work to prevent simultaneously male-on-male aggression and IPV. Future evaluations of these prevention strategies should simultaneously assess the impact of interventions on IPV and male interpersonal aggression.

Various studies are currently investigating ways to prevent lifestyle-related diseases and obesity among workers through interventions using incentive strategies, including price discounts for low-fat snacks and sugar-free beverages at workplace cafeterias or vending machines, and the provision of a free salad bar in cafeterias. Rather than assessing individual or group interventions, we will focus on the effectiveness of nutrition education programs at the population level, which primarily incorporate financial incentive strategies to prevent obesity. This paper describes the protocol of a systematic review that will examine the effectiveness of financial incentive programs at company cafeterias in improving dietary habits, nutrient intake, and obesity prevention. We will conduct searches in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and PsycINFO. Interventions will be assessed using data from randomized control trials (RCTs) and cluster RCTs. However, if few such trials exist, we will include quasi-RCTs. We will exclude controlled before-and-after studies and crossover RCTs. We will assess food-based interventions that include financial incentive strategies (discount strategies or social marketing) for workplace cafeterias, vending machines, and kiosks. Two authors will independently review studies for inclusion and will resolve differences by discussion and, if required, through consultation with a third author. We will assess the risk of bias of included studies according to the Cochrane Collaboration's "risk of bias" tool. The purpose of this paper is to outline the study protocol for a systematic review and meta-analysis that will investigate the effectiveness of population-level, incentive-focused interventions at the workplace cafeteria that aim to promote and prevent obesity. This review will give an important overview of the available evidence about the effectiveness of incentive-based environmental interventions to improve obesity prevention in the workplace and will guide future research in nutrition education and health promotion globally.

Community Peer-Led Falls Prevention Presentations: What Do the Experts Suggest?

Falls among older adults are a major problem. Despite considerable progress in falls prevention research, older adults often show low motivation to engage in recommended preventive strategies. Peer-led falls prevention education for older adults may have potential for bridging the research evidence-practice gap, thereby promoting the uptake of falls prevention strategies. We evaluated peer educators' presentations of falls prevention education to community-dwelling older adults in regard to established criteria that were consistent with adult learning principles, the framework of health behaviour change, falls prevention guidelines, and recommendations for providing falls prevention information. We conducted a within-stage mixed model study using purposive and snowball sampling techniques to recruit 10 experts to evaluate video recordings of the delivery of three peer-led falls prevention presentations. Each expert viewed three videos and rated them using a questionnaire containing both open-ended and closed items. There was a good level of expert agreement across the questionnaire domains. Though the experts rated some aspects of the presentations highly, they thought that the presentations were mainly didactic in delivery, not consistently personally relevant to the older adult audience, and did not encourage older adults to engage in the preventive strategies that were presented. Based on the experts' findings, we developed five key themes and recommendations for the effective delivery of peer-led falls prevention presentations. These included recommending that peer educators share falls prevention messages in a more interactive and experiential manner and that uptake of strategies should be facilitated by encouraging the older adults to develop a personalised action plan. Findings suggest that if peer-led falls prevention presentations capitalise on older adults' capability, opportunity, and motivation, the older adults may be more receptive to take up falls prevention messages.
Assessment of Food Waste Prevention and Recycling Strategies Using a Multilayer Systems Approach.

Food waste (FW) generates large upstream and downstream emissions to the environment and unnecessarily consumes natural resources, potentially affecting future food security. The ecological impacts of FW can be addressed by the upstream strategies of FW prevention or by downstream strategies of FW recycling, including energy and nutrient recovery. While FW recycling is often prioritized in practice, the ecological implications of the two strategies remain poorly understood from a quantitative systems perspective. Here, we develop a multilayer systems framework and scenarios to quantify the implications of food waste strategies on national biomass, energy, and phosphorus (P) cycles, using Norway as a case study. We found that (i) avoidable food waste in Norway accounts for 17% of sold food; (ii) 10% of the avoidable food waste occurs at the consumption stage, while industry and retailers account for only 7%; (iii) the theoretical potential for systems-wide net process energy savings is 16% for FW prevention and 8% for FW recycling; (iv) the theoretical potential for systems-wide P savings is 21% for FW prevention and 9% for FW recycling; (v) while FW recycling results in exclusively domestic nutrient and energy savings, FW prevention leads to domestic and international savings due to large food imports; (vi) most effective is a combination of prevention and recycling, however, FW prevention reduces the potential for FW recycling and therefore needs to be prioritized to avoid potential overcapacities for FW recycling.

Allergic diseases, such as asthma, allergic rhinitis, eczema, and food allergy, are preventable diseases. Primary prevention strategies of allergic diseases have been in scrutiny. Effective prevention strategies maybe started prenatally, postnatally, during infancy, and even during childhood. These guidelines have been prepared by the Philippine Society of Allergy, Asthma and Immunology and the Philippine Society for Pediatric Gastroenterology, Hepatology and Nutrition. They aim to provide evidence-based recommendations for the dietary primary prevention of allergic diseases in children. The primary audience of these guidelines is all healthcare practitioners who manage patients with potential allergic conditions. These guidelines are based on an exhaustive review of evidences, mostly systematic reviews, randomized controlled trials, and cohort studies. However, there are still many gaps in the evidence of dietary primary prevention of allergic diseases. PMID:28487842
Attitudes and Perceptions of Suicide and Suicide Prevention Messages for Asian Americans

Understanding the context of suicidal behaviors is critical for effective suicide prevention strategies. Although suicide is an important topic for Asian Americans, there is limited information about what Asian Americans’ attitudes are towards suicide and their perceptions about the effectiveness of prevention efforts. These questions are critical to examine to provide foundational knowledge for determining how best to intervene. In this study, Asian American (n = 87) and White (n = 87) participants completed self-report indexes on their knowledge of depression and suicide (e.g., estimates of suicide rates), coping attitudes (e.g., help-seeking) and suicide prevention attitudes (e.g., usefulness of PSAs). The results indicate that in comparison to Whites, Asian Americans perceived suicidal behavior to be more common, perceived a stronger link between depression and suicide, less frequently endorsed help-seeking strategies, and reported more concern or distress after viewing a suicide prevention PSA. These preliminary results also suggest the possibility of cultural differences in perceptions of suicide prevention messages. The implications of these findings are discussed with a focus on providing recommendations for exploring suicide prevention efforts for Asian Americans. PMID:26690227
Social development of commercial sex workers in India: an essential step in HIV/AIDS prevention.
Chattopadhyay, Amit; McKaig, Rosemary G
2004-03-01
India has the highest number of HIV/AIDS cases in the world. Current HIV/AIDS prevention strategies are based on regular and appropriate condom use. However, most commercial sex workers (CSWs), who form the core/high-risk groups toward whom the prevention strategy is directed, are disempowered and socioeconomically marginalized. This does not allow them to insist on condom use by the client, especially in absence of governmental structural support. This paper discusses HIV/AIDS prevention issues that relate to CSWs in India; issues that play a vital role in initiation, perpetuation, and expansion of economic activity of CSWs; and those factors that influence the HIV/AIDS preventive practices of CSWs. This paper argues that CSWs can be empowered and emancipated; that HIV/AIDS control and prevention efforts in India must recognize that ad hoc promotion of condom use or similar such programs will not be effective to control HIV/AIDS; and that more extensive developmental work aimed at betterment of living conditions of CSWs is required for effective HIV/AIDS prevention.

Abstract In response to the elevated rate of suicide among U.S. service members, a congressionally mandated task force recommended that the U.S. Department of Defense (DoD) create a unified, comprehensive strategic plan for suicide prevention research to ensure that DoD–funded studies align with DoD's goals. To help meet this objective, a RAND study cataloged the research funded by DoD and other entities that is directly relevant to military personnel, examined the extent to which current research maps to DoD's strategic research needs, and provided recommendations to ensure that proposed research strategies align with the national research strategy and integrate with DoD's data collection and program evaluation strategies. The study found that although DoD is one of the largest U.S. funders of research related to suicide prevention, its current funding priorities do not consistently reflect its research needs. The study indexed each of 12 research goals according to rankings of importance, effectiveness, cultural acceptability, cost, and learning potential provided by experts who participated in a multistep elicitation exercise. The results revealed that research funding is overwhelmingly allocated to prevention goals already considered by experts to be effective. Other goals considered by experts to be important and appropriate for the military context receive relatively little funding and have been the subject of relatively few studies, meaning that there is still much to learn about these strategies. Furthermore, DoD, like other organizations, suffers from a research–to–practice gap. The most promising results from studies funded by DoD and other entities do not always find their way to those responsible for implementing suicide prevention programs that serve military personnel. The RAND study recommended approaches to thoughtfully integrate the latest research findings into DoD's operating procedures to ensure that evidence–based approaches can benefit suicide prevention programs and prevent the further loss of lives to suicide.

The proportion of adults with positive varicella serology is lower in populations from tropical countries. Therefore immigrants to countries with a temperate climate are at risk of acquiring varicella infection during adulthood. We tested two different strategies to prevent varicella outbreaks in housing facilities for asylum seekers arriving in the Canton of Vaud, Switzerland. The first strategy consisted of a rapid response with isolation of the affected individuals and vaccination of the susceptible contacts. The second strategy consisted of a general vaccination upon arrival of all asylum seekers aged 15-39 years with no history of chickenpox. From May 2008 to January 2009 we applied the rapid response strategy. Eight hundred and fifty-eight asylum seekers arrived in the Canton and an attack rate of 2.8% (seven cases among 248 exposed asylum seekers) was observed. The mean cost was US$ 31.35 per asylum seeker. The general vaccination strategy was applied from February 2009 to May 2010, a period during which 966 asylum seekers were registered. This second strategy completely prevented any outbreak at a mean cost of US$ 83.85 per asylum seeker. Of the two analyzed interventions to prevent varicella outbreaks in housing facilities for asylum seekers, the general vaccination strategy was more effective, more sustainable, and ethically preferable, although more costly.

The aim of this paper is to present an economic evaluation of diagnostic technologies using Helicobacter pylori screening strategies for the prevention of gastric cancer as an illustration. A Markov model was constructed to compare the lifetime cost and effectiveness of 4 potential strategies: no screening, the serology test by enzyme-linked immunosorbent assay (ELISA), the stool antigen test (SAT), and the (13)C-urea breath test (UBT) for the detection of H. pylori among a hypothetical cohort of 10,000 Canadian men aged 35 years. Special parameter consideration included the sensitivity and specificity of each screening strategy, which determined the model structure and treatment regimen. The primary outcome measured was the incremental cost-effectiveness ratio between the screening strategies and the no-screening strategy. Base-case analysis and probabilistic sensitivity analysis were performed using the point estimates of the parameters and Monte Carlo simulations, respectively. Compared with the no-screening strategy in the base-case analysis, the incremental cost-effectiveness ratio was $33,000 per quality-adjusted life-year (QALY) for the ELISA, $29,800 per QALY for the SAT, and $50,400 per QALY for the UBT. The probabilistic sensitivity analysis revealed that the no-screening strategy was more cost effective if the willingness to pay (WTP) was <$20,000 per QALY, while the SAT had the highest probability of being cost effective if the WTP was >$30,000 per QALY. Both the ELISA and the UBT were not cost-effective strategies over a wide range of WTP values. Although the UBT had the highest sensitivity and specificity, either no screening or the SAT could be the most cost-effective strategy depending on the WTP threshold values from an economic perspective. This highlights the importance of economic evaluations of diagnostic technologies.

To perform an incremental cost-effectiveness analysis for screening of trisomy 21 (Down syndrome) in the Czech Republic through a decision tree model designed to evaluate the costs and potential risks involved in using different strategies of screening. METHODS AND DATA ANALYSIS: Using decision-analysis modelling, we compared the cost-effectiveness of nine possible screening strategies for trisomy 21: 1. maternal age > or = 35 in first trimester, 2. maternal age > or = 35 in second trimester, 3. second trimester triple test (AFP, hCG, mu E3), 4. nuchal translucency measurement, 5. first trimester serum test (PAPP-A, fbeta-hCG), 6. first trimester combined (nuchal translucency, PAPP-A, fbeta-hCG) not in OSCAR manner, 7. first trimester combined (nuchal translucency, PAPP-A, fbeta-hCG) in OSCAR manner, 8. first trimester combined (nuchal translucency, nasal bone, PAPP-A, fbeta-hCG) not in OSCAR manner, 9. first trimester combined (nuchal translucency, nasal bone, PAPP-A, fbeta-hCG) in OSCAR manner. The analysis is performed from a health care payer perspective using relevant cost and outcomes related to each screening strategy in a cohort of 118,135 pregnant women presenting around 12 weeks of pregnancy in the Czech Republic. Using a computer spreadsheet Excel (Microsoft Corporation, Redmond, Wash) the following outcomes: overall cost-effectiveness, trisomy 21 cases detected, trisomy 21 live birth prevented and euploid losses from invasive procedures were obtained. The incremental cost-effectiveness ratios were also calculated by a comparison of strategy nine and strategy three (the current practice in the Czech Republic). Under the baseline assumptions, the model favors strategy nine as the most cost-effective trisomy 21 screening strategy. This strategy was the least expensive strategy per trisomy 21 cases averted. Although all the other strategies cost less, they all had lower trisomy 21 detection rates and higher numbers of procedure-related losses (except for strategies six and seven, which had same loss rate) compared with strategy nine. All strategies considered were cheaper compared with screening only by maternal age over 35 years. Adding the nasal bone and the OSCAR manner made strategy nine the most cost-effective one. The incremental cost-effectiveness (cost per additional trisomy 21 case prevented) comparing strategy nine and second trimester triple test (current practice in Czech Republic) yielded an additional baseline cost of 219,326 CZK. This would seem not to save money but due to the low false positive rate the test is less costly than might be expected and it is more cost-effective than the current practice in the Czech Republic (3,580,082 CZK for the current practice and 2,469,833 CZK for our strategy in terms of costs per DS case prevented). In our analysis the NT, NB, PAPP-A and fbeta-hCG combined test carried out in the first trimester was the most cost-effective screening strategy for trisomy 21 in the Czech Republic.

Distracted by the Unthought - Suppression and Reappraisal of Mind Wandering under Stereotype Threat.
Schuster, Carolin; Martiny, Sarah E; Schmader, Toni
2015-01-01
Previous research has found that subtle reminders of negative stereotypes about one's group can lead individuals to underperform on stereotype-relevant tests (e.g., women in math, ethnic minorities on intelligence tests). This so called stereotype threat effect can contribute to systematic group differences in performance that can obscure the true abilities of certain social groups and thereby sustain social inequalities. In the present study, we examined processes underlying stereotype threat effects on women's math performance, specifically focusing on the role of suppression of mind wandering (i.e., task-irrelevant thinking) in stereotype threat (ST) and no threat (NT) situations. Based on a process model of stereotype threat effects on performance, we hypothesized that women under stereotype threat spontaneously suppress mind wandering, and that this suppression impairs performance. An alternative regulation strategy that prevents suppression (i.e., reappraising task-irrelevant thoughts as normal) was predicted to prevent stereotype threat effects on performance. We manipulated stereotype threat (ST vs. NT) and cognitive regulation strategy (suppression, reappraisal, or no strategy) and measured women's performance on a math and a concentration task (N = 113). We expected three groups to perform relatively more poorly: Those in ST with either no strategy or suppression and those in NT with a suppression strategy. We tested the performance of these groups against the remaining three groups hypothesized to perform relatively better: those in NT with no strategy or reappraisal and those in ST with reappraisal. The results showed the expected pattern for participants' math performance, but not for concentration achievement. This pattern suggests that ineffective self-regulation by suppressing mind wandering can at least partly explain stereotype threat effects on performance, whereas a reappraisal strategy can prevent this impairment. We discuss implications for the understanding of processes underlying stereotype threat effects and the benefits of reappraising subjective experience under threat.

Preventing malaria in the Peruvian Amazon: a qualitative study in Iquitos, Peru.

In Peru, despite decades of concerted control efforts, malaria remains a significant public health burden. Peru has recently exhibited a dramatic rise in malaria incidence, impeding South America's progress towards malaria elimination. The Amazon basin, in particular the Loreto region of Peru, has been identified as a target for the implementation of intensified control strategies, aiming for elimination. No research has addressed why vector control strategies in Loreto have had limited impact in the past, despite vector control elsewhere being highly effective in reducing malaria transmission. This study employed qualitative methods to explore factors limiting the success of vector control strategies in the region. Twenty semi-structured interviews were conducted among adults attending a primary care centre in Iquitos, Peru, together with 3 interviews with key informants (health care professionals). The interviews focussed on how local knowledge, together with social and cultural attitudes, determined the use of vector control methods. Five themes emerged. (a) Participants believed malaria to be embedded within their culture, and commonly blamed this for a lack of regard for prevention. (b) They perceived a shift in mosquito biting times to early evening, rendering night-time use of bed nets less effective. (c) Poor preventive practices were compounded by a consensus that malaria prevention was the government's responsibility, and that this reduced motivation for personal prevention. (d) Participants confused the purpose of space-spraying. (e) Participants' responses also exposed persisting misconceptions, mainly concerning the cause of malaria and best practices for its prevention. To eliminate malaria from the Americas, region-specific strategies need to be developed that take into account the local social and cultural contexts. In Loreto, further research is needed to explore the potential shift in biting behaviour of Anopheles darlingi, and how this interacts with the population's social behaviours and current use of preventive measures. Attitudes concerning personal responsibility for malaria prevention and long-standing misconceptions as to the cause of malaria and best preventive practices also need to be addressed.
[Historical overview of medical meteorology - the new horizon in medical prevention].
Boussoussou, Nora; Boussoussou, Melinda; Nemes, Attila
2017-02-01
The aim of this article is to draw attention to the medical meteorology from the perspective of the history of science. Unfortunately medical meteorology is not part of the daily medical practice. The climate change is a new challenge for health care worldwide. It concerns millions of people a higher morbidity and mortality rate. Knowing the effects of the meteorological parameters as risk factors can allow us to create new prevention strategies. These new strategies could help to decrease the negative health effects of the meteorological parameters. Nowadays on the field of the medical prevention the medical meteorology is a new horizon and in the future it could play an important role. Health care professionals have the most important role to fight against the negative effects of the global climate change. Orv. Hetil., 2017, 158(5), 187-191.
The prevention of canine leishmaniasis and its impact on public health.
Otranto, Domenico; Dantas-Torres, Filipe
2013-07-01
Canine leishmaniasis (CanL) caused by Leishmania infantum is a vector-borne disease of great veterinary and medical significance. Prevention of CanL requires a combined approach including measures focused on dogs and the environment where the vectors perpetuate. Over past decades, considerable effort has been put towards developing novel and cost-effective strategies against CanL. Vaccination is considered among the most promising tools for controlling CanL, and synthetic pyrethroids are useful and cost-effective in reducing risk of L. infantum infection in dogs. The effectiveness of the use of vaccines plus repellents in preventing L. infantum infection and subsequent disease development should be assessed by means of large-scale, randomized controlled field trials because this combined strategy may become the next frontier in the control of CanL.

Preventing unsafe abortion and limiting its consequences: what can be done?
Misago, C
1994-12-01
The continued illegality of induced abortion in Latin America has led to substantial, preventable maternal mortality and morbidity. The first strategy for preventing unsafe clandestine abortion is to reduce the incidence of unwanted pregnancy through measures such as improved access to effective contraception, post-abortion family planning counseling, health education campaigns aimed at promoting condom use among young people, involvement of men in family planning decision making, biomedical research on safer and more effective male and female contraceptive methods, and empowering women to demand the use of condoms or avoid unwanted intercourse. The second strategy is to reduce abortion-related mortality and morbidity through more effective clinical management of incomplete illegal abortions, introduction of menstrual regulation services, formation of women's solidarity groups aimed at discouraging the practice of self-induced abortion, and, ultimately, abortion legalization.
Targeting Hispanic populations: future research and prevention strategies.
Ramirez, A G; McAlister, A; Gallion, K J; Villarreal, R
1995-01-01
Minority populations face a wide variety of economic, institutional, and cultural barriers to health care. These barriers and low levels of education and income pose significant challenges for health professionals in developing cancer research and prevention-control strategies. It is suggested that specific segments of Hispanic populations fit the model of an underdeveloped country in the intermediate stage of epidemiological transition. Since noncommunicable diseases have not yet fully emerged in some of these Hispanic population segments, the opportunity exists to apply primordial prevention strategies. Such campaigns would focus on dissuading members of these populations from adopting negative health behaviors while promoting positive lifestyle choices. Optimal programs would increase cancer screening participation and discourage risk behaviors through community-oriented, population-based interventions. Future directions in prevention and control efforts for minority populations should include expanded health insurance coverage, improved access to health care, greater emphasis on minority recruitment in health care fields, focused epidemiologic and clinical research, and identification and replication of effective components within existing prevention-control programs.

An increasing barrier to the development and implementation of effective youth smoking prevention and cessation programs involves recruiting adolescents into research studies. Even for non-intervention studies, issues of consent, confidentiality, and motivation to participate are important considerations. In 1996, 11 Prevention Research Center sites across the country conducted qualitative research using focus groups to explore ethnic differences in smoking among adolescents. The diversity in strategies used to interest, motivate, and retain potential focus group subjects provided a rich data set for information about effective strategies and challenges to recruitment. This article presents an overview of recruitment methods used in a multi-site qualitative study on adolescent tobacco use, reports on successful and less successful strategies, and provides recommendations for future recruitment.
[Postpartum depression: we know the risks, can it be prevented?].
Zinga, Dawn; Phillips, Shauna Dae; Born, Leslie
2005-10-01
In the past 20 years, there has been increasing recognition that for some women, pregnancy may be burdened with mood problems, in particular depression, that may impact both mother and child. With identification of risk factors for postpartum depression and a growing knowledge about a biologic vulnerability for mood change following delivery, research has accumulated on attempts to prevent postpartum depression using various psychosocial, psychopharmacologic, and hormonal strategies. The majority of psychosocial and hormonal strategies have shown little effect on postpartum depression. Notwithstanding, results from preliminary trials of interpersonal therapy, cognitive-behavioural therapy, and antidepressants indicate that these strategies may be of benefit. Information on prevention of postpartum depression using dietary supplements is sparse and the available evidence is inconclusive. Although a few studies show promising results, more rigorous trials are required. The abounding negative evidence in the literature indicates that postpartum depression cannot be easily prevented, yet.

The utility of monogamy (in practice) as a strategy for preventing sexually transmitted infections (STIs) was investigated. By reviewing recent literature surrounding monogamous relationships and sexual behaviors, the authors determined that monogamy might not prevent against STIs as expected. First, the authors elucidate the ways in which public health officials and the general public define and interpret monogamy and discuss how this contributes to monogamy as an ineffectual STI prevention strategy. Second, the authors provide evidence that individuals' compliance with monogamy is likely to be low, similar to rates of compliance with other medical advice. Lastly, the authors draw upon recent research findings suggesting that people who label themselves as monogamous are less likely to engage in safer sex behaviors than people who have an explicit agreement with their partner to be non-monogamous. Future research and clinical directions to promote sexual health and destigmatize sexual behaviors are considered. Copyright © 2015. Published by Elsevier Inc.

To tackle the high prevalence of Hepatitis B virus (HBV) infection in North Korea, it is essential that birth doses of HBV vaccines should be administered within 24 hours of birth. As the country fails to provide a Timely Birth Dose (TBD) of HBV vaccine, the efforts of reducing the high prevalence of HBV have been significantly hampered. To examine the cost-effectiveness of vaccination strategies to prevent perinatal transmission of HBV in North Korea, we established a decision tree with a Markov model consisting of selective, universal, and the country's current vaccination program against HBV. The cost-effectiveness analysis was performed from societal and payer's perspectives and evaluated by Disability Adjusted Life Year (DALY). The results suggest that introducing the universal vaccination would prevent 1,866 cases of perinatal infections per 100,000 of the birth cohort of 2013. Furthermore, 900 cases of perinatal infections per 100,000 could be additionally averted if switching to the selective vaccination. The current vaccination is a dominated strategy both from the societal and payer's perspective. The Incremental Cost-Effectiveness Ratio (ICER) between universal and selective vaccination is $267 from the societal perspective and is reported as $273 from the payer's perspective. Based on the assumption that the 2012 Gross Domestic Product (GDP) per capita in North Korea, $582.6 was set for cost-effectiveness criteria, the result of this study indicates that selective vaccination may be a highly cost-effective strategy compared to universal vaccination.

Despite limited evidence of effectiveness, withdrawal (discontinuation or dose reduction) of high risk medications known as "fall-risk increasing drugs" (FRIDs) is typically conducted as a fall prevention strategy based on presumptive benefit. Our objective is to determine the efficacy of fall-risk increasing drugs (FRIDs) withdrawal on the prevention of falls and fall-related complications. We will search for all published and unpublished randomized controlled trials evaluating the effect of FRID withdrawal compared to usual care on the rate of falls, incidence of falls, fall-related injuries, fall-related fractures, fall-related hospitalizations, or adverse effects related to the intervention in adults aged 65 years or older. Electronic database searches will be conducted in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and CINAHL. A grey literature search will be conducted including clinical trial registries and conference proceedings and abstracts. Two reviewers will independently perform in duplicate citation screening, full-text review, data abstraction, and risk of bias assessment. Conflicts will be resolved through team discussion or by a third reviewer if no consensus can be reached. The Grades of Recommendation, Assessment, Development and Evaluation (GRADE) criteria will be used to independently rate overall confidence in effect estimates for each outcome. Results will be synthesized descriptively, and a random effects meta-analysis will be conducted for each outcome if studies are deemed similar methodologically, clinically, and statistically. We will attempt to determine whether a FRID withdrawal strategy alone is effective at preventing falls in older adults. Our results will be used to optimize and focus fall prevention strategies and initiatives internationally with a goal of improving the health of older adults. PROSPERO CRD42016040203.

Tobacco control strategies have contributed to substantial declines in smoking in the United States. However, smoking still remains the single largest preventable cause of disease and premature deaths in the country. Despite the continuing challenges of implementing tobacco control strategies and the pervasive influence of the tobacco industry to undermine such strategies, there are now unprecedented opportunities to prevent smoking initiation, facilitate cessation, and protect nonsmokers from secondhand smoke. In this paper, we briefly review the most recent literature discussing key strategies that have proven effective in tobacco control including regulations on sales and marketing of tobacco products, taxation, and smoke-free legislation. We focused on these three tobacco control strategies because of their potential to positively influence the environment of both minors and adults regardless of their smoking status. Although research has identified significant individual and social predictors of tobacco use, environmental influences are also important risk factors for tobacco use.

New screening technologies and vaccination against human papillomavirus (HPV), the necessary cause of cervical cancer, may impact optimal approaches to prevent cervical cancer. We evaluated the cost-effectiveness of alternative screening strategies to inform cervical cancer prevention guidelines in Norway. We leveraged the primary epidemiologic and economic data from Norway to contextualise a simulation model of HPV-induced cervical cancer. The current cytology-only screening was compared with strategies involving cytology at younger ages and primary HPV-based screening at older ages (31/34+ years), an option being actively deliberated by the Norwegian government. We varied the switch-age, screening interval, and triage strategies for women with HPV-positive results. Uncertainty was evaluated in sensitivity analysis. Current cytology-only screening was less effective and more costly than strategies that involve switching to primary HPV testing in older ages. For unvaccinated women, switching at age 34 years to primary HPV testing every 4 years was optimal given the Norwegian cost-effectiveness threshold ($83,000 per year of life saved). For vaccinated women, a 6-year screening interval was cost-effective. When we considered a wider range of strategies, we found that an earlier switch to HPV testing (at age 31 years) may be preferred. Strategies involving a switch to HPV testing for primary screening in older women is expected to be cost-effective compared with current recommendations in Norway.

Suicide: An Indian perspective
Radhakrishnan, Rajiv; Andrade, Chittaranjan
2012-01-01
Suicide is the third leading cause of death among young adults worldwide. There is a growing recognition that prevention strategies need to be tailored to the region-specific demographics of a country and to be implemented in a culturally-sensitive manner. This review explores the historical, epidemiological and demographic factors of suicide in India and examines the strategies aimed at the prevention of suicide. There has been an increase in the rates of suicide in India over the years, although trends of both increases and decline in suicide rates have been present. Distinct from global demographic risk factors, In India, marital status is not necessarily protective and the female: male ratio in the rate of suicide is higher. The motives and modes of suicide are also distinct from western countries. Preventive strategies implemented at a community level and identifying vulnerable individuals maybe more effective than global strategies. PMID:23372232

Introduction HIV incidence remains high among young women in sub-Saharan Africa in spite of scale-up of HIV testing, behavioural interventions, antiretroviral treatment and medical male circumcision. There is a critical need to critique past approaches and learn about the most effective implementation of evidence-based HIV prevention strategies, particularly emerging interventions such as pre-exposure prophylaxis (PrEP). Discussion Women in sub-Saharan Africa are at increased risk of HIV during adolescence and into their 20s, in part due to contextual factors including gender norms and relationship dynamics, and limited access to reproductive and sexual health services. We reviewed behavioural, behavioural economic and biomedical approaches to HIV prevention for young African women, with a particular focus on the barriers, opportunities and implications for implementing PrEP in this group. Behavioural interventions have had limited impact in part due to not effectively addressing the context, broader sexual norms and expectations, and structural factors that increase risk and vulnerability. Of biomedical HIV prevention strategies that have been tested, daily oral PrEP has the greatest evidence for protection, although adherence was low in two placebo-controlled trials in young African women. Given high efficacy and effectiveness in other populations, demonstration projects of open-label PrEP in young African women are needed to determine the most effective delivery models and whether women at substantial risk are motivated and able to use oral PrEP with sufficient adherence to achieve HIV prevention benefits. Conclusions Social marketing, adherence support and behavioural economic interventions should be evaluated as part of PrEP demonstration projects among young African women in terms of their effectiveness in increasing demand and optimizing uptake and effective use of PrEP. Lessons learned through evaluations of implementation strategies for delivering oral PrEP, a first-generation biomedical HIV prevention product, will inform development of new and less user-dependent PrEP formulations and delivery of an expanding choice of prevention options in HIV prevention programmes for young African women.

Although HIV/AIDS prevention has presented challenges over the past 25 years, prevention does work! To be most effective, however, prevention must be specific to the culture and the nature of the community. Building the capacity of a community for prevention efforts is not an easy process. If capacity is to be sustained, it must be practical and utilize the resources that already exist in the community. Attitudes vary across communities; resources vary, political climates are constantly varied and changing. Communities are fluid-always changing, adapting, growing. They are "ready" for different things at different times. Readiness is a key issue! This article presents a model that has experienced a high level of success in building community capacity for effective prevention/intervention for HIV/AIDS and offers case studies for review. The Community Readiness Model provides both quantitative and qualitative information in a user-friendly structure that guides a community through the process of understanding the importance of the measure of readiness. The model identifies readiness- appropriate strategies, provides readiness scores for evaluation, and most important, involves community stakeholders in the process. The article will demonstrate the importance of developing strategies consistent with readiness levels for more cost-effective and successful prevention efforts.

OBJECTIVES: AIDS service organizations (ASOs) rarely have access to the information needed to implement research-based HIV prevention interventions for their clients. We compared the effectiveness of 3 dissemination strategies for transferring HIV prevention models from the research arena to community providers of HIV prevention services. METHODS: Interviews were conducted with the directors of 74 ASOs to assess current HIV prevention services. ASOs were randomized to programs that provided (1) technical assistance manuals describing how to implement research-based HIV prevention interventions, (2) manuals plus a staff training workshop on how to conduct the implementation, or (3) manuals, the training workshop, and follow-up telephone consultation calls. Follow-up interviews determined whether the intervention model had been adopted. RESULTS: The dissemination package that provided ASOs with implementation manuals, staff training workshops, and follow-up consultation resulted in more frequent adoption and use of the research-based HIV prevention intervention for gay men, women, and other client populations. CONCLUSIONS: Strategies are needed to quickly transfer research-based HIV prevention methods to community providers of HIV prevention services. Active collaboration between researchers and service agencies results in more successful program adoption than distribution of implementation packages alone. PMID:10897186

Lost productivity represents a considerable portion of the total economic burden of colorectal cancer (CRC), but cost-effectiveness studies of CRC prevention and control have not included these costs and therefore underestimate potential savings from CRC prevention and control. To use microsimulation modeling study to estimate and project productivity costs of CRC and to model the savings from four approaches to reducing CRC incidence and mortality: risk factor reduction, improved screening, improved treatment, and a simultaneous approach where all three strategies are implemented. A model was developed to project productivity losses from CRC using the U.S. population with CRC incidence and mortality projected through the year 2020. Outcome measures were CRC mortality, morbidity, and productivity savings. With 2005 levels in risk factors, screening, and treatment, 48,748 CRC deaths occurred in 2010, amounting to $21 billion of lost productivity. Using prevention and treatment strategies simultaneously, 3586 deaths could have been avoided in 2010, leading to a savings of $1.4 billion. Cumulatively, by 2020, simultaneous strategies that reduce risk factors and increase screening and treatment could result in 101,353 deaths avoided and $33.9 billion in savings in reduced productivity loss. Improved screening rates alone led to nearly $14.7 billion in savings between 2005 and 2020, followed by risk factor reduction ($12.4 billion) and improved treatment ($8.4 billion). The savings in productivity loss from strategies to reduce CRC incidence and mortality are substantial, providing evidence that CRC prevention and control strategies are likely to be cost-saving.

PrEP as peri-conception HIV prevention for women and men
Heffron, Renee; Pintye, Jillian; Matthews, Lynn T.; Weber, Shannon; Mugo, Nelly
2016-01-01
Daily oral tenofovir (TDF)-based pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy and recommended for men and women with substantial risk of HIV acquisition. The peri-conception period, the stage prior to pregnancy when condom use is necessarily reduced, has elevated HIV risk that can be mitigated by PrEP use. Data from a randomized trial suggest that peri-conception PrEP use by HIV-seronegative women does not increase the risk of pregnancy loss, birth defects or congenital anomalies, preterm birth, or infant growth faltering. Women considering PrEP use throughout pregnancy must weigh the known increased risk of HIV acquisition with unknown risks of drug effects on infant growth. PrEP has been used safely by HIV-seronegative men with HIV-seropositive female partners who have become pregnant. As an effective user-controlled HIV prevention strategy, PrEP offers autonomy and empowerment for HIV prevention and can be recommended alongside antiretroviral therapy, fertility screening, vaginal self-insemination, intercourse timed to peak fertility, medically assisted reproduction, and other safer conception strategies to provide multiple options. The integration of PrEP into safer conception programs is warranted and will safely reduce HIV transmission to women, men and children during the peri-conception period. PMID:26993627

Fatigue is common among physicians and adversely affects their performance. To identify strategies that attending physicians use when fatigued to maintain clinical performance in the intensive care unit (ICU). We conducted a qualitative study using focus groups and structured interviews of attending ICU physicians working in academic centers in Canada. In three focus group meetings, we engaged a total of 11 physicians to identify strategies used to prevent and cope with fatigue. In the focus groups, 21 cognitive strategies were identified and classified into 9 categories (minimizing number of tasks, using techniques to improve retention of details, using a structured approach to patient care, asking for help, improving opportunities for focusing, planning ahead, double-checking, adjusting expectations, and modulating alertness). In addition, various lifestyle strategies were mentioned as important in preventing fatigue (e.g., protecting sleep before call, adequate exercise, and limiting alcohol). Telephone interviews were then conducted (n = 15 physicians) with another group of intensivists. Structured questions were asked about the strategies identified in the focus groups that were most useful during ICU activities. In the interviews, the most useful and frequently used strategies were prioritizing tasks that need to be done immediately and postponing tasks that can wait, working systematically, using a structured approach, and avoiding distractions. ICU physicians reported using a variety of deliberate cognitive and lifestyle strategies to prevent and cope with fatigue. Given the low cost and intuitive nature of the majority of these strategies, further investigations should be done to better characterize their effectiveness in improving performance.

Many donors and countries are striving to respond to the HIV/AIDS epidemic by implementing prevention programmes. However, the resources available for providing these activities relative to needs are limited. Hence, decision-makers must choose among various types of interventions. Cost information, both measures of cost and cost-effectiveness, serves as a critical input into the processes of setting priorities and allocating resources efficiently. This paper reviews the cost and cost-effectiveness evidence base of HIV/AIDS prevention programmes in low- and middle-income countries (LMICs). None of the studies found have complete cost data for a full range of HIV/AIDS prevention programmes in any one country. However, the range of studies highlight the relative emphasis of different types of HIV/AIDS prevention strategies by region, reflecting the various modes of transmission and hence, to a certain extent, the stage of the epidemic. The costing methods applied and results obtained in this review give rise to questions of reliability, validity and transparency. First, not all of the studies report the methods used to calculate the costs, and/or do not provide all the necessary data inputs such that recalculation of the results is possible. Secondly, methods that are documented vary widely, rendering different studies, even within the same country and programme setting, largely incomparable. Finally, even with consistent and replicable measurement, the results as presented are generally not comparable because of the lack of a common outcome measure. Therefore, the extent to which the available cost and cost-effectiveness evidence base on HIV/AIDS prevention strategies can provide guidance to decision-makers is limited, and there is an urgent need for the generation of this knowledge for planning and decision-making.
Why don't northern American solutions to drinking and driving work in southern America?
Pechansky, Flavio; Chandran, Aruna
2012-07-01
While individual studies from several South American countries have shown driving while intoxicated to be a problem, there are no objective systematically collected alcohol-associated driving data obtained in most South American countries. This limits their ability to implement and enforce targeted prevention strategies, evaluate whether proven prevention efforts from North America (particularly the United States and Canada) can be transferred to the South, and to sustain momentum for the improvement of road safety by demonstrating that previously implemented legal and policy changes are effective. The aim of this paper is to discuss the abysmal differences that exist between northern and southern American countries regarding the current status of driving while intoxicated prevention strategies-their implementation, impacts and effects-using Brazil as a case example. We propose a three-pronged approach to close this northern-southern American gap in driving while intoxicated prevention and intervention: (a) systematic collection on road traffic crash/injury/death as well as risk factor data, (b) passage of laws without loopholes requiring compliance with blood alcohol concentration testing and (c) provision of appropriate training and equipment to the police in concomitance with vigilant enforcement. Resources and energies must be put towards data collection, implementation of prevention strategies and enforcement in order to decrease the unacceptably high rates of these preventable driving while intoxicated deaths. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.
Eye Injury Prevention for the Pediatric Population.
Hoskin, Annette K; Philip, Swetha S; Yardley, Anne-Marie E; Mackey, David A
2016-05-01
Each year an estimated 3.3 to 5.7 million pediatric eye injuries occur worldwide. It is widely reported that 90% of ocular injuries are preventable. Our aim was to identify legislation and policies, education, and mandatory eye protection strategies that have successfully contributed to reducing rates of children's eye injuries. A literature search was conducted using the terms "pediatric" or "children" or "adolescent" and "ocular" or "eye" and "protection" or "injury prevention." Articles were retrieved based on titles and abstracts and assessed in the context of our research question. Strategies identified aimed at reducing ocular trauma fell into 3 broad categories: legislation and policies, education, and personal eye protection. Policies including restrictions on the sale and supply of certain consumer products, mandatory vehicle seatbelts, and laminated windscreens in vehicles have assisted in reducing children's eye injuries. Educational tools aimed at children and their caregivers have been effective in changing attitudes to eye health and safety. Effective pediatric eye injury prevention systems require a multifactorial approach combining legislation, policies, standards, education, and personal eye protection to limit exposure to ocular hazards. A paucity of standardized measurement and lack of funding have limited advances in the field of children's eye injury prevention. Improved eye injury surveillance and research funding along with collaboration with health care providers are important components for strategies to prevent pediatric ocular trauma.
Uncovering effective strategies for hearing loss prevention
Morata, Thais C.; Meinke, Deanna

Occupational health agencies, researchers and policy makers have recognized the need for evidence on the effectiveness of interventions designed to reduce or prevent workplace injuries and illnesses. While many workplaces comply with legal or obligatory requirements and implement recommended interventions, few publications exist documenting the effectiveness of these actions. Additionally, some workplaces have discovered through their own processes, novel ways to reduce the risk of injury. Peer-reviewed information on the effectiveness of the many strategies and approaches currently in use could help correct weaknesses, or further encourage their adoption and expansion. The evaluation of intervention effectiveness would certainly contribute to improved worker health and safety. This need is particularly relevant regarding noise exposure in the workplace and hearing loss prevention interventions. In a 2006 review of the U.S. National Institute for Occupational Safety and Health (NIOSH) Hearing Loss Research Program, the independent National Academies of Sciences recommended that NIOSH place greater emphasis on identifying the effectiveness of hearing loss prevention measures on the basis of outcomes that are as closely related as possible to reducing noise exposure and work related hearing loss (http://www.nap.edu/openbook.php?record_id=11721). NIOSH used two different approaches to address that recommendation: the first one was to conduct research, including broad systematic reviews on the effectiveness of interventions to prevent occupational noise-induced hearing loss. The second was to create an award program, the Safe-In-Sound Excellence in Hearing Loss Prevention Award™, to identify and honor excellent real-world examples of noise control and other hearing loss prevention practices and innovations.

To estimate the cost-effectiveness of the levonorgestrel intrauterine device (IUD) as an endometrial cancer prevention strategy in obese women. A modified Markov model was used to compare IUD placement at age 50 with usual care among women with a body mass index (BMI, kg/m) 40 or greater or BMI 30 or greater. The effects of obesity on incidence and survival were incorporated. The IUD was assumed to confer a 50% reduction in cancer incidence over 5 years. Costs of IUD and cancer care were included. Clinical outcomes were cancer diagnosis and deaths from cancer. Incremental cost-effectiveness ratios were calculated in 2015 U.S. dollars per year of life saved. One-way and two-way sensitivity analyses and Monte Carlo probabilistic analyses were performed. For a 50 year old with BMI 40 or greater, the IUD strategy is costlier and more effective than usual care with an incremental cost-effectiveness ratio of $74,707 per year of life saved. If the protective effect of the levonorgestrel IUD is assumed to be 10 years, the incremental cost-effectiveness ratio decreases to $37,858 per year of life saved. In sensitivity analysis, a levonorgestrel IUD that reduces cancer incidence by at least 68% in women with BMIs of 40 or greater or costs less than $500 is potentially cost-effective. For BMI 30 or greater, the incremental cost-effectiveness ratio of IUD strategy is $137,223 per year of life saved compared with usual care. In Monte Carlo analysis, IUD placement for BMI 40 or greater is cost-effective in 50% of simulations at a willingness-to-pay threshold of $100,000 per year of life saved. The levonorgestrel IUD is a potentially cost-effective strategy for prevention of deaths from endometrial cancer in obese women.

Tobacco consumption contributes significantly to the global burden of disease. The prevalence of smoking is estimated to be increasing in many low-income countries, including Tanzania, especially among women and youth. Even so, the implementation of tobacco control measures has been discouraging in the country. Efforts to foster investment in tobacco control are hindered by lack of evidence on what works and at what cost. We aim to estimate the cost and cost-effectiveness of population-based tobacco control strategies in the prevention of cardiovascular diseases (CVD) in Tanzania. A cost-effectiveness analysis was performed using an Excel-based Markov model, from a governmental perspective. We employed an ingredient approach and step-down methodologies in the costing exercise following a government perspective. Epidemiological data and efficacy inputs were derived from the literature. We used disability-adjusted life years (DALYs) averted as the outcome measure. A probabilistic sensitivity analysis was carried out with Ersatz to incorporate uncertainties in the model parameters. Our model results showed that all five tobacco control strategies were very cost-effective since they fell below the ceiling ratio of one GDP per capita suggested by the WHO. Increase in tobacco taxes was the most cost-effective strategy, while a workplace smoking ban was the least cost-effective option, with a cost-effectiveness ratio of US$5 and US$267, respectively. Even though all five interventions are deemed very cost-effective in the prevention of CVD in Tanzania, more research on budget impact analysis is required to further assess the government's ability to implement these interventions.

Obesity, the prevalence of which is still on the rise, is related to the main chronic diseases affecting the health of the population. Therefore, in 2004, the World Health Assembly approved the Global Strategy on Diet, Physical Activity and Health with the aim of reducing the risk factors of nontransmittable diseases related to unhealthy diets and physical inactivity. Along this same line, the Spanish Ministry of Health and Consumer Affairs began implementing the NAOS Strategy in 2005 as a platform from which to include and promote all those initiatives contributing to achieving the necessary social change in the promotion of healthy eating and the prevention of a sedentary lifestyle by meeting certain specific challenges within different scopes of action. The NAOS Strategy extends far beyond the healthcare and educational areas, by combining actions in all those sectors of society playing a role in preventing obesity. Informative campaigns, agreements with public and private institutions, voluntary working agreements, educational programs and supporting health promotion initiatives are some of the activities being carried out as part of the NAOS Strategy. Carrying out these activities and incorporating yet others, in conjunction with the work of evaluating and monitoring all of these activities, will be what is going to make it possible to maintain a high degree of effectiveness in preventing obesity.

The development of smoking cessation and relapse-prevention interventions for pregnant and postpartum women is a public health priority. However, researchers have consistently reported substantial difficulty in accruing this population into clinical trials. The problem is particularly acute for relapse-prevention studies, which must recruit women who have already quit smoking because of their pregnancy. Although an important target for tobacco control efforts, these individuals represent an extremely small subgroup of the general population. This paper describes multiple recruitment strategies utilized for a clinical trial of a self-help relapse-prevention program for pregnant women. The effectiveness of the strategies and the direct expense per participant accrued are provided. A proactive recruitment strategy (telephoning women whose phone numbers were purchased from a marketing firm) was ultimately much more successful than a variety of reactive strategies (advertisement, press releases, direct mail, web placement, healthcare provider outreach). There were few differences between proactively and reactively recruited participants on baseline variables; the primary difference was that the former had smoked fewer cigarettes per day and reported lower nicotine dependence prior to quitting. Strengths and limitations of the recruitment strategies are discussed. PMID:18188749

In this commentary, we briefly summarize and give examples of evaluations done by the International Agency for Research on Cancer, WHO (IARC-WHO, Lyon, France) about the identification of carcinogenic substances or agents and the evaluation of the efficacy and effectiveness of cancer preventive substances, agents or strategies. In the 1970's the IARC initiated a series of Monographs on the Evaluation of Carcinogenic Risks to Humans for the purposes of primary prevention. During the last 35 years of the IARC Monographs, many agents that are important to the public health perspective have been evaluated. The agent or exposure is described andmore » classified according to the wording of one of the following groups: group 1, carcinogenic to humans; group 2A, probably carcinogenic to humans; group 2B, possibly carcinogenic to humans; group 3, not classifiable as to its carcinogenicity to humans; group 4, probably not carcinogenic to humans. In 1997, the IARC started a new series of handbooks, the IARC Handbooks of Cancer Prevention, which aimed for the evaluation of efficacy and effectiveness of cancer preventive agents and strategies. The process of evaluation is quite similar to the IARC Monographs. In total, 10 Handbooks were published in topics such as mammography screening, cervical cancer screening, consumption of fruits and vegetables, cruciferous vegetables, and weight control and physical activity. We discuss in general terms ways of preventing cancer and of evaluating preventive strategies, giving as example mammography screening.« less

This study explores perceptions of causes of and solutions for school violence in a sample of 202 parents interviewed in the wake of nationally publicized school shootings. We also investigate the effects the school shootings had on children, parents' perceptions regarding firearms, and changes in parenting behavior. Parents exhibited strong support for almost all proposed causes and solutions, and we address their desire for immediate and often invasive interventions to prevent future violence. We contrast parents' perceptions with their own parenting behaviors and with literature on effective interventions. Results are discussed within the context of policy implications.Editors' Strategic Implications: Parents' perceptions and behaviors are frequently influenced by history effects. The national attention received by school shootings provided an opportunity for exploration of those perceptions and self-reported behaviors. The authors provide evidence from timely surveys that parents struggle with identifying causal factors that may contribute to school violence and consequently support a myriad of strategies for intervention including very invasive environmental preventive strategies. The findings suggest that social scientists should play a proactive role in translating research-supported preventive strategies to effective replications in the community and make research available in formats that are available and comprehensible by the lay public.

We present a combined epidemiological and economic model for control of diseases spreading on local and small-world networks. The disease is characterized by a pre-symptomatic infectious stage that makes detection and control of cases more difficult. The effectiveness of local (ring-vaccination or culling) and global control strategies is analysed by comparing the net present values of the combined cost of preventive treatment and illness. The optimal strategy is then selected by minimizing the total cost of the epidemic. We show that three main strategies emerge, with treating a large number of individuals (global strategy, GS), treating a small number of individuals in a well-defined neighbourhood of a detected case (local strategy) and allowing the disease to spread unchecked (null strategy, NS). The choice of the optimal strategy is governed mainly by a relative cost of palliative and preventive treatments. If the disease spreads within the well-defined neighbourhood, the local strategy is optimal unless the cost of a single vaccine is much higher than the cost associated with hospitalization. In the latter case, it is most cost-effective to refrain from prevention. Destruction of local correlations, either by long-range (small-world) links or by inclusion of many initial foci, expands the range of costs for which the NS is most cost-effective. The GS emerges for the case when the cost of prevention is much lower than the cost of treatment and there is a substantial non-local component in the disease spread. We also show that local treatment is only desirable if the disease spreads on a small-world network with sufficiently few long-range links; otherwise it is optimal to treat globally. In the mean-field case, there are only two optimal solutions, to treat all if the cost of the vaccine is low and to treat nobody if it is high. The basic reproduction ratio, R0, does not depend on the rate of responsive treatment in this case and the disease always invades (but might be stopped afterwards). The details of the local control strategy, and in particular the optimal size of the control neighbourhood, are determined by the epidemiology of the disease. The properties of the pathogen might not be known in advance for emerging diseases, but the broad choice of the strategy can be made based on economic analysis only. PMID:21653570

Australian youth engage in behaviour that threatens their health and wellbeing. National surveys report that about a third of young Australians have tried an illicit drug. High rates of substance use and risky sexual behaviour among young Australians suggest that effective prevention efforts based on empirical evidence need to be expanded. Church-associated organisations are an untapped resource that could be used to improve the health and welfare of young people. We describe eight evidence-based elements to consider in designing strategies to prevent high-risk behaviour in young people.
False fame prevented: avoiding fluency effects without judgmental correction.
Topolinski, Sascha; Strack, Fritz
2010-05-01
Three studies show a way to prevent fluency effects independently of judgmental correction strategies by identifying and procedurally blocking the sources of fluency variations, which are assumed to be embodied in nature. For verbal stimuli, covert pronunciations are assumed to be the crucial source of fluency gains. As a consequence, blocking such pronunciation simulations through a secondary oral motor task decreased the false-fame effect for repeatedly presented names of actors (Experiment 1) as well as prevented increases in trust due to repetition for brand names and names of shares in the stock market (Experiment 2). Extending this evidence beyond repeated exposure, we demonstrated that blocking oral motor simulations also prevented fluency effects of word pronunciation on judgments of hazardousness (Experiment 3). Concerning the realm of judgment correction, this procedural blocking of (biasing) associative processes is a decontamination method not considered before in the literature, because it is independent of exposure control, mood, motivation, and post hoc correction strategies. The present results also have implications for applied issues, such as advertising and investment decisions. 2010 APA, all rights reserved

Background Although highly effective prevention interventions exist, the epidemic of paediatric HIV continues to challenge control efforts in resource-limited settings. We reviewed the cost-effectiveness of interventions to prevent mother-to-child transmission (MTCT) of HIV in low- and middle-income countries (LMICs). This article presents syntheses of evidence on the costs, effects and cost-effectiveness of HIV MTCT strategies for LMICs from the published literature and evaluates their implications for policy and future research. Methods Candidate studies were identified through a comprehensive database search including PubMed, Embase, Cochrane Library, and EconLit restricted by language (English or French), date (January 1st, 1994 to January 17th, 2011) and article type (original research). Articles reporting full economic evaluations of interventions to prevent or reduce HIV MTCT were eligible for inclusion. We searched article bibliographies to identify additional studies. Two authors independently assessed eligibility and extracted data from studies retained for review. Study quality was appraised using a modified BMJ checklist for economic evaluations. Data were synthesised in narrative form. Results We identified 19 articles published in 9 journals from 1996 to 2010, 16 concerning sub-Saharan Africa. Collectively, the articles suggest that interventions to prevent paediatric infections are cost-effective in a variety of LMIC settings as measured against accepted international benchmarks. In concentrated epidemics where HIV prevalence in the general population is very low, MTCT strategies based on universal testing of pregnant women may not compare well against cost-effectiveness benchmarks, or may satisfy formal criteria for cost-effectiveness but offer a low relative value as compared to competing interventions to improve population health. Conclusions and Recommendations Interventions to prevent HIV MTCT are compelling on economic grounds in many resource-limited settings and should remain at the forefront of global HIV prevention efforts. Future cost-effectiveness analyses can help to ensure that pMTCT interventions for LMICs reach their full potential by focussing on unanswered questions in four areas: local assessment of rapidly evolving HIV MTCT options; strategies to improve coverage and reach underserved populations; evaluation of a more comprehensive set of MTCT approaches including primary HIV prevention and reproductive counselling; integration of HIV MTCT and other sexual and reproductive health services.

The authors reviewed studies to identify methods for dental operators to use to prevent the development of musculoskeletal disorders, or MSDs. The authors reviewed studies that related to the prevention of MSDs among dental operators. Some studies investigated the relationship between the biomechanics of seated working postures and physiological damage or pain. Other studies suggested that repeated unidirectional twisting of the trunk can lead to low back pain, while yet other studies examined the detrimental effects of working in one position for prolonged periods. Additional studies confirmed the roles that operators' flexibility and core strength can play in balanced musculoskeletal health and the need for operators to know how to properly adjust ergonomic equipment. This review indicates that strategies to prevent the multifactorial problem of dental operators' developing MSDs exist. These strategies address deficiencies in operator position, posture, flexibility, strength and ergonomics. Education and additional research are needed to promote an understanding of the complexity of the problem and to address the problem's multifactorial nature. A comprehensive approach to address the problem of MSDs in dentistry represents a paradigm shift in how operators work. New educational models that incorporate a multifactorial approach can be developed to help dental operators manage and prevent MSDs effectively.

It is well established that blood pressure lowering is effective for the primary prevention of stroke and other cardiovascular disorders in subjects with blood pressures as low as 140/90 mmHg, and up to 80 years of age. Despite this knowledge, blood pressure levels are controlled in less than 25% of the hypertensive population worldwide. It has taken longer to prove that blood pressure lowering is equally effective for the prevention of recurrent stroke. The results of PROGRESS (Perindopril Protection Against Recurrent Stroke Study) have confirmed that a perindopril-based regimen in subjects with cerebrovascular disease substantially reduces the incidence of secondary stroke and primary myocardial infarction. It is daunting to recall that it has taken almost two decades for beta-blockers to be widely used for the secondary prevention of myocardial infarction, since widespread use of the PROGRESS regimen would prevent more than half a million strokes worldwide each year. The real challenge now is to implement novel and effective strategies for the control of blood pressure and other cardiovascular risk factors worldwide. Strategies should include lifestyle measures, such as stopping smoking, exercise and reducing overweight. There is a real need to identify hypertensive subjects and treat them with blood pressure lowering drugs for primary prevention. In subjects with established cardiovascular disease, consideration should be given to a range of proven interventions for secondary prevention, such as blood pressure lowering, irrespective of current blood pressure, anti-platelet drugs, statins for lowering cholesterol and glycaemic control in diabetics. Among new strategies to lower overall cardiovascular risk, consideration should be given to the development of single-pill combinations of drugs of known efficacy, including various combinations of ACE inhibitors, diuretics, beta-blockers, aspirin and statins, among others.

The purpose of this systematic review was to determine if sock, antiperspirant, or barrier strategies were effective in prevention of friction blisters in wilderness and outdoor pursuits. A search of PubMed and EMBASE was conducted. Title, abstract, and full text articles were screened by 2 authors using predetermined inclusion and exclusion criteria to identify prospective controlled trials investigating prevention methods for friction blisters involving the foot. Only blisters associated with wilderness and outdoor pursuits (running, hiking, marching, etc.) were considered. Extraction of a predetermined data set was accomplished using a piloted form. Confidence in effect estimates were determined utilizing the Scottish Intercollegiate Guidelines Network methodology checklist. Literature search resulted in 806 discrete articles. After screening, 11 studies were identified for inclusion in systematic review. Included studies investigated 5 sock, 3 antiperspirant, and 3 barrier strategies. Only 2 articles were determined to have moderate confidence in effect estimate. Clinical and methodologic diversity precluded meta-analysis. Despite the high frequency, discomfort, and associated cost there is a paucity of high-quality quality evidence in support of socks, antiperspirants, or barriers for the prevention of friction blisters. Moderate confidence in effect estimate suggests that paper tape may be an effective form of barrier prevention. Published by Elsevier Inc.

One of the goals of the Global Measles and Rubella Strategic Plan is the reduction in global measles mortality, with high measles vaccination coverage as one of its core components. While measles mortality has been reduced more than 79%, the disease remains a major cause of childhood vaccine preventable disease burden globally. Measles immunization requires a two-dose schedule and only countries with strong, stable immunization programs can rely on routine services to deliver the second dose. In the Democratic Republic of Congo (DRC), weak health infrastructure and lack of provision of the second dose of measles vaccine necessitates the use of supplementary immunization activities (SIAs) to administer the second dose. We modeled three vaccination strategies using an age-structured SIR (Susceptible-Infectious-Recovered) model to simulate natural measles dynamics along with the effect of immunization. We compared the cost-effectiveness of two different strategies for the second dose of Measles Containing Vaccine (MCV) to one dose of MCV through routine immunization services over a 15-year time period for a hypothetical birth cohort of 3 million children. Compared to strategy 1 (MCV1 only), strategy 2 (MCV2 by SIA) would prevent a total of 5,808,750 measles cases, 156,836 measles-related deaths and save U.S. $199 million. Compared to strategy 1, strategy 3 (MCV2 by RI) would prevent a total of 13,232,250 measles cases, 166,475 measles-related deaths and save U.S. $408 million. Vaccination recommendations should be tailored to each country, offering a framework where countries can adapt to local epidemiological and economical circumstances in the context of other health priorities. Our results reflect the synergistic effect of two doses of MCV and demonstrate that the most cost-effective approach to measles vaccination in DRC is to incorporate the second dose of MCV in the RI schedule provided that high enough coverage can be achieved.

Maximizing both efficiency and equity are core considerations for population health. These considerations can result in tension in population health science as we seek to improve overall population health while achieving equitable health distributions within populations. Limited work has explored empirically the consequences of different population health intervention strategies on the burden of disease and on within- and between-group differences in disease. To address this gap, we compared the impact of four simulated interventions using data from the National Health and Nutrition Examination Survey. In particular, we focus on assessing how population and high-risk primary prevention and population and high-risk secondary interventions efforts to reduce smoking behavior influence systolic blood pressure (SBP) and hypertension, and how such strategies influence inequalities in SBP by income. The greatest reductions in SBP mean and standard deviation resulted from the population secondary prevention. High-risk primary and secondary prevention and population secondary prevention programs all yielded substantial reductions in hypertension prevalence. The effect of population primary prevention did little to decrease population SBP mean and standard deviation, as well as hypertension prevalence. Both high-risk strategies had a larger impact in the low-income population, leading to the greatest narrowing the income-related gap in disease. The population prevention strategies had a larger impact in the high-income population. Population health approaches must consider the potential impact on both the whole population and also on those with different levels of risk for disease within a population, including those in under-represented or under-served groups.

Gastric cancer (GC) surveillance based on oesophagogastroduodenoscopy (OGD) appears to be a promising strategy for GC prevention. By evaluating the cost-effectiveness of endoscopic surveillance in Singaporean Chinese, this study aimed to inform the implementation of such a program in a population with a low to intermediate GC risk. USING A REFERENCE STRATEGY OF NO OGD INTERVENTION, WE EVALUATED FOUR STRATEGIES: 2-yearly OGD surveillance, annual OGD surveillance, 2-yearly OGD screening and 2-yearly screening plus annual surveillance in Singaporean Chinese aged 50-69 years. From a perspective of the healthcare system, Markov models were built to simulate the life experience of the target population. The models projected discounted lifetime costs ($), quality adjusted life year (QALY), and incremental cost-effectiveness ratio (ICER) indicating the cost-effectiveness of each strategy against a Singapore willingness-to-pay of $46,200/QALY. Deterministic and probabilistic sensitivity analyses were used to identify the influential variables and their associated thresholds, and to quantify the influence of parameter uncertainties respectively. With an ICER of $44,098/QALY, the annual OGD surveillance was the optimal strategy while the 2-yearly surveillance was the most cost-effective strategy (ICER = $25,949/QALY). The screening-based strategies were either extendedly dominated or cost-ineffective. The cost-effectiveness heterogeneity of the four strategies was observed across age-gender subgroups. Eight influential parameters were identified each with their specific thresholds to define the choice of optimal strategy. Accounting for the model uncertainties, the probability that the annual surveillance is the optimal strategy in Singapore was 44.5%. Endoscopic surveillance is potentially cost-effective in the prevention of GC for populations at low to intermediate risk. Regarding program implementation, a detailed analysis of influential factors and their associated thresholds is necessary. Multiple strategies should be considered in order to recommend the right strategy for the right population.

Recent increases in cardiovascular risk-factor prevalences have led to new national policy recommendations of universal screening for primary prevention of cardiovascular disease in Malaysia. This study assessed whether the current national policy recommendation of universal screening was optimal, by comparing the effectiveness and impact of various cardiovascular screening strategies. Data from a national population based survey of 24 270 participants aged 30 to 74 was used. Five screening strategies were modelled for the overall population and by gender; universal and targeted screening (four age cut-off points). Screening strategies were assessed based on the ability to detect high cardiovascular risk populations (effectiveness), incremental effectiveness, impact on cardiovascular event prevention and cost of screening. 26.7% (95% confidence limits 25.7, 27.7) were at high cardiovascular risk, men 34.7% (33.6, 35.8) and women 18.9% (17.8, 20). Universal screening identified all those at high-risk and resulted in one high-risk individual detected for every 3.7 people screened, with an estimated cost of USD60. However, universal screening resulted in screening an additional 7169 persons, with an incremental cost of USD115,033 for detection of one additional high-risk individual in comparison to targeted screening of those aged ≥35 years. The cost, incremental cost and impact of detection of high-risk individuals were more for women than men for all screening strategies. The impact of screening women aged ≥45 years was similar to universal screening in men. Targeted gender- and age-specific screening strategies would ensure more optimal utilisation of scarce resources compared to the current policy recommendations of universal screening.

Primary prevention in public health: an analysis of basic assumptions.
Ratcliffe, J; Wallack, L
1985-01-01
The common definition of primary prevention is straightforward; but how it is transformed into a framework to guide action is based on personal and societal feelings and beliefs about the basis for social organization. This article focuses on the two contending primary prevention strategies of health promotion and health protection. The contention between the two strategies stems from a basic disagreement about disease causality in modern society. Health promotion is based on the "lifestyle" theory of disease causality, which sees individual health status linked ultimately to personal decisions about diet, stress, and drug habits. Primary prevention, from this perspective, entails persuading individuals to forgo their risk-taking, self-destructive behavior. Health protection, on the other hand, is based on the "social-structural" theory of disease causality. This theory sees the health status of populations linked ultimately to the unequal distribution of social resources, industrial pollution, occupational stress, and "anti-health promotion" marketing practices. Primary prevention, from this perspective, requires changing existing social and, particularly, economic policies and structures. In order to provide a basis for choosing between these contending strategies, the demonstrated (i.e., past) impact of each strategy on the health of the public is examined. Two conclusions are drawn. First, the health promotion strategy shows little potential for improving the public health, because it systematically ignores the risk-imposing, other-destructive behavior of influential actors (policy-makers and institutions) in society. And second, effective primary prevention efforts entail an "upstream" approach that results in far-reaching sociopolitical and economic change.

In recent decades, numerous studies have shown a significant increase in violence during childhood and adolescence. These data suggest the importance of implementing programs to prevent and reduce violent behavior. The study aimed to design a program of emotional intelligence (EI) for adolescents and to assess its effects on variables related to violence prevention. The possible differential effect of the program on both genders was also examined. The sample comprised 148 adolescents aged from 13 to 16 years. The study used an experimental design with repeated pretest–posttest measures and control groups. To measure the variables, four assessment instruments were administered before and after the program, as well as in the follow-up phase (1 year after the conclusion of the intervention). The program consisted of 20 one-hour sessions. The pretest–posttest ANCOVAs showed that the program significantly increased: (1) EI (attention, clarity, emotional repair); (2) assertive cognitive social interaction strategies; (3) internal control of anger; and (4) the cognitive ability to analyze negative feelings. In the follow-up phase, the positive effects of the intervention were generally maintained and, moreover, the use of aggressive strategies as an interpersonal conflict-resolution technique was significantly reduced. Regarding the effect of the program on both genders, the change was very similar, but the boys increased assertive social interaction strategies, attention, and emotional clarity significantly more than the girls. The importance of implementing programs to promote socio-emotional development and prevent violence is discussed. PMID:26082743

Antibody-Based Preventive and Therapeutic Strategies Against HIV.
Fabra-Garcia, Amanda; Beltran, Carolina; Sanchez-Merino, Victor; Yuste, Eloisa
2016-01-01
Over the years, numerous studies have been carried out demonstrating the role of antibodies in HIV control leading to the development of antibody-based therapeutic and prophylactic strategies. The objective of this review is to provide updated information on the role of antibodies in the prevention and control of HIV infection and the strategies against HIV that have been designed based on this information. Passive transfer of anti-HIV antibodies in animal models has proven the efficacy of certain antibodies in the prevention and treatment of infection. The capacity of antibodies to control the virus was first attributed to their neutralizing capacity. However, we now know that there are other Fc-mediated antibody activities associated with virus protection. When it comes to better understanding protection against HIV, we ought to pay particular attention to mucosal immune responses. The evidence accumulated so far indicates that an effective vaccine against HIV should generate both mucosal IgAs and systemic IgGs. Due to the problematic induction of protective anti-HIV antibodies, several groups have developed alternative approaches based on antibody delivery via gene therapy vectors. Experiments in animal models with these vectors have shown impressive protection levels and this strategy is now being clinically trialed. Taking into account all the information included in this review, it seems evident that anti-HIV-1 antibodies play an important role in virus control and prevention. This review aims to give an overview of the strategies used and the advances in antibody-based preventive and therapeutic strategies against HIV-1.

Centre-based childcare services represent a promising setting to target the prevention of excessive weight gain in preschool-aged children. Staff training is a key component of multi-strategy interventions to improve implementation of effective physical activity and nutrition promoting practices for obesity prevention in childcare services. This randomised controlled trial aimed to examine whether an active telephone-based strategy to invite childcare-service staff to attend a training workshop was effective in increasing the proportion of services with staff attending training, compared with a passive strategy. Services were randomised to an active telephone-based or a passive-recruitment strategy. Those in the active arm received an email invitation and one to three follow-up phone calls, whereas services in the passive arm were informed of the availability of training only via newsletters. The proportion of services with staff attending the training workshop was compared between the two arms. One hundred and twenty-eight services were included in this study. A significantly larger proportion (52%) of services in the active arm compared with those in the passive-strategy arm (3.1%) attended training (d.f.=1, χ2=34.3; P<0.001). An active, telephone-based recruitment strategy significantly increased the proportion of childcare services with staff attending training. Further strategies to improve staff attendance at training need to be identified and implemented. SO WHAT?: Active-recruitment strategies including follow-up telephone calls should be utilised to invite staff to participate in training, in order to maximise the use of training as an implementation strategy for obesity prevention in childcare services.

The last three decades have seen a series of HIV interventions in sub-Saharan Africa. However, youths still have a mixture of correct and incorrect HIV/AIDS knowledge of transmission routes and prevention strategies. Previous studies have identified parents and peers as the most important socializing agents for youths. This paper assesses the relationships between family structure, family/peer communication about sexuality and accurate knowledge of transmission routes and prevention strategies. Data were drawn from the Cameroon Family Life and Health Survey (CFHS) conducted in 2002. The CFHS collected information on a representative sample of 4950 people aged 10 years and over nested within 1765 selected households from the 75 localities forming the administrative prefecture of Bandjoun, using detailed questionnaires about family, HIV/AIDS/STDs knowledge, sexual behaviors, contraception, health, media exposure, household assets and neighborhood characteristics. The survey cooperation rates were high (97%). For the purpose of this study, a sub-sample of 2028 unmarried youths aged 12-29 years was utilized. Overall, 42% of respondents reported accurate knowledge of documented HIV transmission routes whereas 21% of them had inaccurate knowledge such as AIDS can be transmitted through mosquito bites or casual contact with an infected person. Only 9% of respondents were knowledgeable about all HIV prevention strategies. Multivariate analyses showed that family structure, communication with parents/guardians and peers about sexual topics were significantly associated with accurate HIV knowledge. Additionally, age, education, sexual experience and migration had significant effects on accurate knowledge. Finally, living in poor households and disadvantaged neighborhoods significantly increased inaccurate knowledge of HIV transmission modes and prevention strategies. This paper evidenced the limited effects of HIV interventions/programmes in sub-Saharan Africa. Indeed, few respondents reported accurate knowledge about HIV transmission routes and prevention strategies. Findings showed that the role of family environment as source of accurate HIV knowledge transmission routes and prevention strategies is of paramount significance; however, families have been poorly integrated in the design and implementation of the first generation of HIV interventions. There is an urgent need that policymakers work together with families to improve the efficiency of these interventions. Peer influences is likely controversial because of the double positive effect of peer-to-peer communication on both accurate and inaccurate knowledge of HIV transmission routes.

Economic and societal pressures influence modern medical practice to develop and implement prevention strategies. Anterior cruciate ligament (ACL) injury devastates the knee joint leading to short term disability and long term sequelae. Due to the high risk of long term osteoarthritis in all treatment populations following ACL injury, prevention is the only effective intervention for this life-altering disruption in knee health. The “Sequence of Prevention” Model provides a framework to monitor progress towards the ultimate goal of preventing ACL injuries. Utilizing this model, our multidisciplinary collaborative research team has spent the last decade working to delineate injury mechanisms, identify injury risk factors, predict which athletes are at-risk for injury, and develop ACL injury prevention programs. Within this model of injury prevention, modifiable factors (biomechanical and neuromuscular) related to injury mechanisms likely provide the best opportunity for intervention strategies aimed to decrease the risk of ACL injury, particularly in female athletes. Knowledge advancements have led to the development of potential solutions that allow athletes to compete with lowered risk of ACL injury. Design and integration of personalized clinical assessment tools and targeted prevention strategies for athletes at high risk for ACL injury may transform current prevention practices and ultimately significantly reduce ACL injury incidence. This 2016 OREF Clinical Research Award focuses on the authors' work and contributions to the field. The author's acknowledge the many research groups who have contributed to the current state of knowledge in the fields of ACL injury mechanisms, injury risk screening and injury prevention strategies.

Context Population-level coverage for immunization against many vaccine-preventable diseases remains below optimal rates in the U.S. The Community Preventive Services Task Force recently recommended several interventions to increase vaccination coverage based on systematic reviews of the evaluation literature. The present study provides the economic results from those reviews. Evidence acquisition A systematic review was conducted (search period, January 1980 through February 2012) to identify economic evaluations of 12 interventions recommended by the Task Force. Evidence was drawn from included studies; estimates were constructed for the population reach of each strategy, cost of implementation, and cost per additional vaccinated person because of the intervention. Analyses were conducted in 2014. Evidence synthesis Reminder systems, whether for clients or providers, were among the lowest-cost strategies to implement and the most cost effective in terms of additional people vaccinated. Strategies involving home visits and combination strategies in community settings were both costly and less cost effective. Strategies based in settings such as schools and managed care organizations that reached the target population achieved additional vaccinations in the middle range of cost effectiveness. Conclusions The interventions recommended by the Task Force differed in reach, cost, and cost effectiveness. This systematic review presents the economic information for 12 effective strategies to increase vaccination coverage that can guide implementers in their choice of interventions to fit their local needs, available resources, and budget.

Older Adult Falls: Effective Approaches to Prevention
Dellinger, Ann
2017-01-01
Purpose The issue of older adult falls combines a problem with high incidence and high injury susceptibility with an increasing population at risk. A firm understanding of both fall risk factors and effective strategies is required to reduce risk and prevent these injuries. Recent Findings Each year, 28.7% of older adults aged ≥65 sustain a fall. At the national level, this represents 29 million falls resulting in 27,000 deaths and 7 million injuries requiring medical treatment or restricted activity for at least 1 day. There are several strategies that have been shown to effectively reduce the risk or the incidence of falls. Summary More than 90% of older adults see a medical provider at least once a year providing an opportunity to identify and address fall risk factors. Comprehensive fall prevention in the primary care setting is both feasible and practical. PMID:28845383
Obesity and fractures in postmenopausal women.
Compston, Juliet
2015-07-01
Although obesity was previously believed to be protective against fracture, there is now evidence that a significant proportion of fractures in postmenopausal women occur in those who are obese. In this article the epidemiology, pathophysiology and clinical management of fractures in obese postmenopausal women are discussed with particular focus on the site specificity of the effect of BMI on fracture, interactions between fat and bone and risk assessment and prevention of fractures. There is similarity in many respects between risk factors for fracture in obese and nonobese women, although falls may play a particularly important role in the obese. Treatment rates in obese postmenopausal women with fracture are currently low, and further studies are required to establish effective preventive strategies. Fractures in obese postmenopausal women contribute significantly to the overall fracture burden in this population. Further work is required to establish their pathophysiology and to develop effective preventive strategies.

Introduction Young key populations, defined in this article as men who have sex with men, transgender persons, people who sell sex and people who inject drugs, are at particularly high risk for HIV. Due to the often marginalized and sometimes criminalized status of young people who identify as members of key populations, there is a need for HIV prevention packages that account for the unique and challenging circumstances they face. Pre-exposure prophylaxis (PrEP) is likely to become an important element of combination prevention for many young key populations. Objective In this paper, we discuss important challenges to HIV prevention among young key populations, identify key components of a tailored combination prevention package for this population and examine the role of PrEP in these prevention packages. Methods We conducted a comprehensive review of the evidence to date on prevention strategies, challenges to prevention and combination prevention packages for young key populations. We focused specifically on the role of PrEP in these prevention packages and on young people under the age of 24, and 18 in particular. Results and discussion Combination prevention packages that include effective, acceptable and scalable behavioural, structural and biologic interventions are needed for all key populations to prevent new HIV infections. Interventions in these packages should meaningfully involve beneficiaries in the design and implementation of the intervention, and take into account the context in which the intervention is being delivered to thoughtfully address issues of stigma and discrimination. These interventions will likely be most effective if implemented in conjunction with strategies to facilitate an enabling environment, including increasing access to HIV testing and health services for PrEP and other prevention strategies, decriminalizing key populations’ practices, increasing access to prevention and care, reducing stigma and discrimination, and fostering community empowerment. PrEP could offer a highly effective, time-limited primary prevention for young key populations if it is implemented in combination with other programs to increase access to health services and encourage the reliable use of PrEP while at risk of HIV exposure. Conclusions Reductions in HIV incidence will only be achieved through the implementation of combinations of interventions that include biomedical and behavioural interventions, as well as components that address social, economic and other structural factors that influence HIV prevention and transmission.

The problems associated with the use of alcohol, tobacco, and other drugs (ATOD) extract a significant health, social, and economic toll on American society. While the field of substance abuse prevention has made great strides during the past decade, two major challenges remain. First, the field has been disorganized and fragmented with respect to its research and prevention practices; that is, there are often separate ATOD prevention "specialists." Second, both the prevention researchers who test the efficacy of specific prevention strategies and the practitioners who implement prevention efforts often lack an overall perspective to guide strategy selection. To address these limitations, we present an ATOD causal model that seeks to identify those variables (Domains) that are theoretically salient and empirically connected across alcohol, tobacco, and illicit drugs. For the researcher, the model demonstrates important commonalities, as well as gaps, in the literature. For the practitioner, the model is a means to recognize both the complexity of the community system that produces ATOD problems and the multiple intervention points that are possible within this system. Researchers and practitioners are thus challenged to work synergistically to find effective and cost-effective approaches to change or reduce ATOD use and associated problems.

Recent technological advances have increased the interest and ability of lay audiences to create messages; however, the feasibility of incorporating lay multimedia messages into health campaigns has seldom been examined. Drawing on the principle of cultural grounding and narrative engagement theory, this article seeks to examine what types of messages adolescents believe are most effective in persuading their peers to resist substance use and to provide empirical data on the extent to which audience-generated intervention messages are consistent with the associated campaign philosophy and branding. Data for the current study are prevention messages created by students as part of a four-lesson substance use prevention “booster” program delivered to eighth-grade students in 20 rural schools in Pennsylvania and Ohio during 2010–2011. Content analysis results indicate that didactic message strategies were more common in audience-generated messages than narrative strategies, although strategy was somewhat dependent on the medium used. Two of the most common strategies that adolescents used to persuade peers not to use substances were negative consequences and identity appeals, and messages varied in the degree to which they were consistent with the theoretical underpinnings and program philosophy of the prevention campaign. Implications of the current study for understanding the social construction of substance use prevention messages among adolescents and incorporating audience-generated messages in health communication campaigns are discussed.

Gastrointestinal radiation injury: prevention and treatment.
Shadad, Abobakr K; Sullivan, Frank J; Martin, Joseph D; Egan, Laurence J
2013-01-14
With the recent advances in detection and treatment of cancer, there is an increasing emphasis on the efficacy and safety aspects of cancer therapy. Radiation therapy is a common treatment for a wide variety of cancers, either alone or in combination with other treatments. Ionising radiation injury to the gastrointestinal tract is a frequent side effect of radiation therapy and a considerable proportion of patients suffer acute or chronic gastrointestinal symptoms as a result. These side effects often cause morbidity and may in some cases lower the efficacy of radiotherapy treatment. Radiation injury to the gastrointestinal tract can be minimised by either of two strategies: technical strategies which aim to physically shift radiation dose away from the normal intestinal tissues, and biological strategies which aim to modulate the normal tissue response to ionising radiation or to increase its resistance to it. Although considerable improvement in the safety of radiotherapy treatment has been achieved through the use of modern optimised planning and delivery techniques, biological techniques may offer additional further promise. Different agents have been used to prevent or minimize the severity of gastrointestinal injury induced by ionising radiation exposure, including biological, chemical and pharmacological agents. In this review we aim to discuss various technical strategies to prevent gastrointestinal injury during cancer radiotherapy, examine the different therapeutic options for acute and chronic gastrointestinal radiation injury and outline some examples of research directions and considerations for prevention at a pre-clinical level.

The effectiveness of currently available effective preventive strategies for contrast-induced acute kidney injury (CIAKI) is a matter of debate. We performed a Bayesian random-effects network meta-analysis of 124 trials (28 240 patients) comparing a total of 10 strategies: saline, statin, N-acetylcysteine (NAC), sodium bicarbonate (NaHCO 3 ), NAC+NaHCO 3 , ascorbic acid, xanthine, dopaminergic agent, peripheral ischemic preconditioning, and natriuretic peptide. Compared with saline, the risk of CIAKI was reduced by using statin (odds ratio [OR], 0.42; 95% credible interval [CrI], 0.26-0.67), xanthine (OR, 0.32; 95% CrI, 0.17-0.57), ischemic preconditioning (OR, 0.48; 95% CrI, 0.26-0.87), NAC+NaHCO 3 (OR, 0.50; 95% CrI, 0.33-0.76), NAC (OR, 0.68; 95% CrI, 0.55-0.84), and NaHCO 3 (OR, 0.66; 95% CrI, 0.47-0.90). The benefit of statin therapy was consistent across multiple sensitivity analyses, whereas the efficacy of all the other strategies was questioned by restricting the analysis to high-quality trials. Overall, high heterogeneity was observed for comparisons involving xanthine and ischemic preconditioning, although the impact of NAC and xanthine was probably influenced by publication bias/small-study effect. Hydration alone was the least effective preventive strategy for CIAKI. Meta-regressions did not reveal significant associations with baseline creatinine and contrast volume. In patients with diabetes mellitus, no strategy was found to reduce the incidence of CIAKI. In patients undergoing percutaneous coronary procedures, statin administration is associated with a marked and consistent reduction in the risk of CIAKI compared with saline. Although xanthine, NAC, NaHCO 3 , NAC+NaHCO 3 , ischemic preconditioning, and natriuretic peptide may have nephroprotective effects, these results were not consistent across multiple sensitivity analyses. © 2017 American Heart Association, Inc.

The main purpose of our meta-analysis was to investigate the effect of workplace dietary intervention on several variables. We made a systematic literature search by selecting articles published up to September 2009. Only 18 studies were deemed suitable for inclusion criteria considered in our meta-analysis. Among the dietary variables there was significant difference between the two groups after the administration of nutritional intervention programs. A significant improvement was also observed between the anthropometric and metabolic variables. No significant change was instead documented in relation to functional variables (systolic and diastolic pressure). Workplace dietary intervention, improving nutritional, anthropometrical and metabolic variables, can be identified as effective prevention strategy toward chronic diseases.

Zinc deficiency is a major cause of childhood morbidity and mortality. The WHO/UNICEF strategy for zinc supplementation as adjunctive therapy for diarrhea is poorly implemented. A conference of experts in zinc nutrition and gastrointestinal disorders was convened to consider approaches that might complement the current recommendation and what research was needed to develop these approaches. Several key points were identified. The design of novel zinc interventions would be facilitated by a better understanding of how disturbed gut function, such as environmental (or tropical) enteropathy, affects zinc absorption, losses, and homeostasis. Because only 10% of zinc stores are able to be rapidly turned over, and appear to be rapidly depleted by acute intestinal illness, they are probably best maintained by complementary regular supplementation in a primary prevention strategy rather than secondary prevention triggered by acute diarrhea. The assessment of zinc status is challenging and complex without simple, validated measures to facilitate field testing of novel interventions. Zinc bioavailability may be a crucial factor in the success of primary prevention strategies, and a range of options, all still inadequately explored, might be valuable in improving zinc nutrition. Some therapeutic actions of zinc on diarrhea seem attributable to pharmacologic effects, whereas others are related to the reversal of deficiency (ie, nutritional). The distinction between these 2 mechanisms cannot be clarified given the insensitivity of serum zinc to identify subclinical deficiency states. Why zinc seems to be less effective than expected at all ages, and ineffective for secondary prevention of diarrhea in children <12 mo of age, remains unclear. It was concluded that a reframing of the current recommendation is warranted with consideration of how to better optimize and deliver zinc and whether to provide a complementary public health primary prevention zinc strategy. This requires careful consideration of the zinc product to be used as well as strategies for its delivery. PMID:25240082

Early clinical trials of a Clostridium difficile toxoid vaccine show efficacy in preventing C. difficile infection (CDI). The optimal patient group to target for vaccination programmes remains unexplored. This study performed a model-based evaluation of the effectiveness of different CDI vaccination strategies, within the context of existing infection prevention and control strategies such as antimicrobial stewardship. An individual-based transmission model of CDI in a high-risk hospital setting was developed. The model incorporated data on patient movements between the hospital, and catchment populations from the community and long-term care facilities (LTCF), using English national and local level data for model-parameterisation. We evaluated vaccination of: (1) discharged patients who had an CDI-occurrence in the ward; (2) LTCF-residents; (3) Planned elective surgical admissions and (4) All three strategies combined. Without vaccination, 10.9 [Interquartile range: 10.0-11.8] patients per 1000 ward admissions developed CDI, of which 31% were ward-acquired. Immunising all three patient groups resulted in a 43% [42-44], reduction of ward-onset CDI on average. Among the strategies restricting vaccination to one target group, vaccinating elective surgical patients proved most effective (35% [34-36] reduction), but least efficient, requiring 146 [133-162] courses to prevent one ICU-onset case. Immunising LTCF residents was most efficient, requiring just 13 [11-16] courses to prevent one case, but considering this only comprised a small group of our hospital population, it only reduced ICU-onset CDI by 9% [8-11]. Vaccination proved most efficient when ward-based transmission rates and antimicrobial consumption were high. Strategy success depends on the interaction between hospital and catchment populations, and importantly, consideration of importations of CDI from outside the hospital which we found to substantially impact hospital dynamics. Vaccination may be most desirable in settings or patient groups where levels of broad-spectrum antimicrobial use are high and difficult to reduce. Copyright © 2016 Elsevier Ltd. All rights reserved.

Cardiovascular disease is the most important cause of morbidity and mortality in the world and low-dose aspirin is considered the cornerstone of the cardiovascular disease prevention. However, low-dose aspirin use is associated with gastrointestinal adverse effects in the whole gastrointestinal tract. In this setting, co-therapy with a proton pump inhibitor is the most accepted strategy to reduce aspirin related upper gastrointestinal damage. In addition, some adverse effects have been described with proton pump inhibitors long term use. Areas covered: Low-dose aspirin related beneficial and adverse effects in cardiovascular system and gastrointestinal tract are reviewed. In addition, this manuscript summarizes current data on upper gastrointestinal damage prevention and adverse events with proton pump inhibition. Finally, we discuss the benefit/risk ratio of proton pump inhibitor use in patients at risk of gastrointestinal damage taking low-dose aspirin. Expert commentary: Nowadays, with the current available evidence, the combination of low-dose aspirin with proton pump inhibitor is the most effective therapy for cardiovascular prevention in patients at high gastrointestinal risk. However, further studies are needed to discover new effective strategies with less related adverse events.

Clostridium difficile infections are a global clinical concern and are one of the leading causes of nosocomial outbreaks. Preventing these infections has benefited from multidisciplinary infection control strategies and new antibiotics, but the problem persists. Probiotics are effective in preventing antibiotic-associated diarrhea and may also be a beneficial strategy for C. difficile infections, but randomized controlled trials are scarce. This meta-analysis pools 21 randomized, controlled trials for primary prevention of C. difficile infections (CDI) and four trials for secondary prevention of C. difficile recurrences and assesses the efficacy of specific probiotic strains. Four probiotics significantly improved primary CDI prevention: (Saccharomyces boulardii, Lactobacillus casei DN114001, a mixture of L. acidophilus and Bifidobacterium bifidum, and a mixture of L. acidophilus, L. casei and L. rhamnosus). None of the tested probiotics significantly improved secondary prevention of CDI. More confirmatory randomized trials are needed to establish if probiotics are useful for preventing C. difficile infections. PMID:27025619

Background Clinical practice guidelines have traditionally recommended blood pressure treatment based primarily on blood pressure thresholds. In contrast, using predicted cardiovascular risk has been advocated as a more effective strategy to guide treatment decisions for cardiovascular disease (CVD) prevention. We aimed to compare outcomes from a blood pressure-lowering treatment strategy based on predicted cardiovascular risk with one based on systolic blood pressure (SBP) level. Methods and findings We used individual participant data from the Blood Pressure Lowering Treatment Trialists’ Collaboration (BPLTTC) from 1995 to 2013. Trials randomly assigned participants to either blood pressure-lowering drugs versus placebo or more intensive versus less intensive blood pressure-lowering regimens. We estimated 5-y risk of CVD events using a multivariable Weibull model previously developed in this dataset. We compared the two strategies at specific SBP thresholds and across the spectrum of risk and blood pressure levels studied in BPLTTC trials. The primary outcome was number of CVD events avoided per persons treated. We included data from 11 trials (47,872 participants). During a median of 4.0 y of follow-up, 3,566 participants (7.5%) experienced a major cardiovascular event. Areas under the curve comparing the two treatment strategies throughout the range of possible thresholds for CVD risk and SBP demonstrated that, on average, a greater number of CVD events would be avoided for a given number of persons treated with the CVD risk strategy compared with the SBP strategy (area under the curve 0.71 [95% confidence interval (CI) 0.70–0.72] for the CVD risk strategy versus 0.54 [95% CI 0.53–0.55] for the SBP strategy). Compared with treating everyone with SBP ≥ 150 mmHg, a CVD risk strategy would require treatment of 29% (95% CI 26%–31%) fewer persons to prevent the same number of events or would prevent 16% (95% CI 14%–18%) more events for the same number of persons treated. Compared with treating everyone with SBP ≥ 140 mmHg, a CVD risk strategy would require treatment of 3.8% (95% CI 12.5% fewer to 7.2% more) fewer persons to prevent the same number of events or would prevent 3.1% (95% CI 1.5%–5.0%) more events for the same number of persons treated, although the former estimate was not statistically significant. In subgroup analyses, the CVD risk strategy did not appear to be more beneficial than the SBP strategy in patients with diabetes mellitus or established CVD. Conclusions A blood pressure-lowering treatment strategy based on predicted cardiovascular risk is more effective than one based on blood pressure levels alone across a range of thresholds. These results support using cardiovascular risk assessment to guide blood pressure treatment decision-making in moderate- to high-risk individuals, particularly for primary prevention. PMID:29558462

We aimed to compare outcomes from a blood pressure-lowering treatment strategy based on predicted cardiovascular risk with one based on systolic blood pressure (SBP) level. We used individual participant data from the Blood Pressure Lowering Treatment Trialists' Collaboration (BPLTTC) from 1995 to 2013. Trials randomly assigned participants to either blood pressure-lowering drugs versus placebo or more intensive versus less intensive blood pressure-lowering regimens. We estimated 5-y risk of CVD events using a multivariable Weibull model previously developed in this dataset. We compared the two strategies at specific SBP thresholds and across the spectrum of risk and blood pressure levels studied in BPLTTC trials. The primary outcome was number of CVD events avoided per persons treated. We included data from 11 trials (47,872 participants). During a median of 4.0 y of follow-up, 3,566 participants (7.5%) experienced a major cardiovascular event. Areas under the curve comparing the two treatment strategies throughout the range of possible thresholds for CVD risk and SBP demonstrated that, on average, a greater number of CVD events would be avoided for a given number of persons treated with the CVD risk strategy compared with the SBP strategy (area under the curve 0.71 [95% confidence interval (CI) 0.70-0.72] for the CVD risk strategy versus 0.54 [95% CI 0.53-0.55] for the SBP strategy). Compared with treating everyone with SBP ≥ 150 mmHg, a CVD risk strategy would require treatment of 29% (95% CI 26%-31%) fewer persons to prevent the same number of events or would prevent 16% (95% CI 14%-18%) more events for the same number of persons treated. Compared with treating everyone with SBP ≥ 140 mmHg, a CVD risk strategy would require treatment of 3.8% (95% CI 12.5% fewer to 7.2% more) fewer persons to prevent the same number of events or would prevent 3.1% (95% CI 1.5%-5.0%) more events for the same number of persons treated, although the former estimate was not statistically significant. In subgroup analyses, the CVD risk strategy did not appear to be more beneficial than the SBP strategy in patients with diabetes mellitus or established CVD. A blood pressure-lowering treatment strategy based on predicted cardiovascular risk is more effective than one based on blood pressure levels alone across a range of thresholds. These results support using cardiovascular risk assessment to guide blood pressure treatment decision-making in moderate- to high-risk individuals, particularly for primary prevention.

Maintaining transient stability is a basic requirement for secure power system operations. Preventive control deals with modifying the system operating point to withstand probable contingencies. In this article, a decision tree (DT)-based on-line preventive control strategy is proposed for transient instability prevention of power systems. Given a stability database, a distance-based feature estimation algorithm is first applied to identify the critical generators, which are then used as features to develop a DT. By interpreting the splitting rules of DT, preventive control is realised by formulating the rules in a standard optimal power flow model and solving it. The proposed method is transparent in control mechanism, on-line computation compatible and convenient to deal with multi-contingency. The effectiveness and efficiency of the method has been verified on New England 10-machine 39-bus test system.

We systematically searched 9 biomedical and social science databases (1980-2012) for primary and secondary interventions that prevented or reduced 2 or more adolescent health risk behaviors (tobacco use, alcohol use, illicit drug use, risky sexual behavior, aggressive acts). We identified 44 randomized controlled trials of universal or selective interventions and were effective for multiple health risk behaviors. Most were school based, conducted in the United States, and effective for multiple forms of substance use. Effects were small, in line with findings for other universal prevention programs. In some studies, effects for more than 1 health risk behavior only emerged at long-term follow-up. Integrated prevention programs are feasible and effective and may be more efficient than discrete prevention strategies.

[Nudge in prevention… an alternative approach or a dead end?].
Cambon, Linda
2016-01-01
Prevention policies need to be more effective. Practitioners and decision-makers therefore need to innovate in the field of prevention policies and interventions by adapting methods or strategies used in other domains. Nudges, considered to be an attractive technique in view of its efficacy, are one of these innovations.However, the use of nudges in prevention policies raises ethical debates which will be summarized in this article. After recalling the definition of nudging, this article describes the ethical debates concerning three issues and emphasizes the way they can reflect a beneficial, democratic, freedom-based and autonomous society.In conclusion, this article encourages prevention practitioners and decision-makers to adopt a larger view before transferring strategies from other sectors and especially to consider all ethical issues.
[Venous catheter-related infections].
Ferrer, Carmen; Almirante, Benito
2014-02-01
Venous catheter-related infections are a problem of particular importance, due to their frequency, morbidity and mortality, and because they are potentially preventable clinical processes. At present, the majority of hospitalized patients and a considerable number of outpatients are carriers of these devices. There has been a remarkable growth of knowledge of the epidemiology of these infections, the most appropriate methodology for diagnosis, the therapeutic and, in particular, the preventive strategies. Multimodal strategies, including educational programs directed at staff and a bundle of simple measures for implementation, applied to high-risk patients have demonstrated great effectiveness for their prevention. In this review the epidemiology, the diagnosis, and the therapeutic and preventive aspects of these infections are updated. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Chronic fibrotic liver diseases such as viral hepatitis eventually develop liver cirrhosis, which causes occurrence of hepatocellular carcinoma (HCC). Given the limited therapeutic efficacy in advanced HCC, prevention of HCC development could be an effective strategy for improving patient prognosis. However, there is still no established therapy to meet the goal. Studies have elucidated a wide variety of molecular mechanisms and signaling pathways involved in HCC development. Genetically-engineered or chemically-treated experimental models of cirrhosis and HCC have been developed and shown their potential value in investigating molecular therapeutic targets and diagnostic biomarkers for HCC prevention. In this review, we overview potential targets of prevention and currently available experimental models, and discuss strategies to translate the findings into clinical practice. PMID:22873223

Expanding essential health services through non-government organisations (NGOs) is a central strategy for achieving universal health coverage in many low-income and middle-income countries. Human immunodeficiency virus (HIV) prevention services for key populations are commonly delivered through NGOs and have been demonstrated to be cost-effective and of substantial global public health importance. However, funding for HIV prevention remains scarce, and there are growing calls internationally to improve the efficiency of HIV prevention programmes as a key strategy to reach global HIV targets. To date, there is limited evidence on the determinants of costs of HIV prevention delivered through NGOs; and thus, policymakers have little guidance in how best to design programmes that are both effective and efficient. We collected economic costs from the Indian Avahan initiative, the largest HIV prevention project conducted globally, during the first 4 years of its implementation. We use a fixed-effect panel estimator and a random-intercept model to investigate the determinants of average cost. We find that programme design choices such as NGO scale, the extent of community involvement, the way in which support is offered to NGOs and how clinical services are organised substantially impact average cost in a grant-based payment setting. © 2016 The Authors.

Clinical trials have demonstrated that it is possible to prevent diabetes through lifestyle modification, pharmacological intervention, and surgery. This review aims to summarize the effectiveness of these various therapeutic interventions in reducing the risk of progression of prediabetes to diabetes, and address the challenges to implement a diabetes prevention program at a community level. Strategies focusing on intensive lifestyle changes are not only efficient but cost-effective and/or cost-saving. Indeed, lifestyle intervention in people at high risk for type 2 diabetes mellitus (T2DM) has been successful in achieving sustained behavioral changes and a reduction in diabetes incidence even after the counseling is stopped. Although prediabetes is associated with health and economic burdens, it has not been adequately addressed by interventions or regulatory agencies in terms of prevention or disease management. Lifestyle intervention strategies to prevent T2DM should be distinct for different populations around the globe and should emphasize sex, age, ethnicity, and cultural and geographical considerations to be feasible and to promote better compliance. The translation of diabetes prevention research at a population level, especially finding the most effective methods of preventing T2DM in various societies and cultural settings remains challenging, but must be accomplished to stop this worldwide epidemic.

Response to drug administration is a primary determinant for treatment success. Sex and gender disparities play a role in determining the efficacy and safety of the most commonly used medications suggesting the need for a sex-tailored approach in prescription. Statins are a cost-effective strategy for cardiovascular disease (CVD) prevention. While statins are similarly effective in secondary CVD prevention, some concerns raised by conflicting data reported in primary CVD prevention clinical trials. The small representation of women in clinical trials and the fewer rates of events due to the lower female baseline CVD risk may have conditioned contradictory meta-analysis findings. Specifically, benefits outweigh disadvantages of statin therapy in women with a high CVD risk, while several doubts exist for the primary prevention of women at low-intermediate CVD risk. Furthermore, disparities between women and men in medication adherence may influence statin efficacy in CVD prevention. The sex-dependent impact of adverse side effects is one of the reasons advocated for explaining the gender gap, but it is not evidence-proved. The present review summarizes the sex and gender differences in the use of statins, pointing out new perspectives and opening issues in sex-tailored CVD prevention strategy.

Background To tackle the high prevalence of Hepatitis B virus (HBV) infection in North Korea, it is essential that birth doses of HBV vaccines should be administered within 24 hours of birth. As the country fails to provide a Timely Birth Dose (TBD) of HBV vaccine, the efforts of reducing the high prevalence of HBV have been significantly hampered. Methods To examine the cost-effectiveness of vaccination strategies to prevent perinatal transmission of HBV in North Korea, we established a decision tree with a Markov model consisting of selective, universal, and the country’s current vaccination program against HBV. The cost-effectiveness analysis was performed from societal and payer’s perspectives and evaluated by Disability Adjusted Life Year (DALY). Results The results suggest that introducing the universal vaccination would prevent 1,866 cases of perinatal infections per 100,000 of the birth cohort of 2013. Furthermore, 900 cases of perinatal infections per 100,000 could be additionally averted if switching to the selective vaccination. The current vaccination is a dominated strategy both from the societal and payer’s perspective. The Incremental Cost-Effectiveness Ratio (ICER) between universal and selective vaccination is $267 from the societal perspective and is reported as $273 from the payer’s perspective. Conclusion Based on the assumption that the 2012 Gross Domestic Product (GDP) per capita in North Korea, $582.6 was set for cost-effectiveness criteria, the result of this study indicates that selective vaccination may be a highly cost-effective strategy compared to universal vaccination.

Asymptomatic Peripheral Arterial Disease (PAD) is associated with greater risk of acute cardiovascular events. This study aims to determine the cost-effectiveness of one time only PAD screening using Ankle Brachial Index (ABI) test and subsequent anti platelet preventive treatment (low dose aspirin or clopidogrel) in individuals at high risk for acute cardiovascular events compared to no screening and no treatment using decision analytic modelling. A probabilistic Markov model was developed to evaluate the life time cost-effectiveness of the strategy of selective PAD screening and consequent preventive treatment compared to no screening and no preventive treatment. The analysis was conducted from the Dutch societal perspective and to address decision uncertainty, probabilistic sensitivity analysis was performed. Results were based on average values of 1000 Monte Carlo simulations and using discount rates of 1.5% and 4% for effects and costs respectively. One way sensitivity analyses were performed to identify the two most influential model parameters affecting model outputs. Then, a two way sensitivity analysis was conducted for combinations of values tested for these two most influential parameters. For the PAD screening strategy, life years and quality adjusted life years gained were 21.79 and 15.66 respectively at a lifetime cost of 26,548 Euros. Compared to no screening and treatment (20.69 life years, 15.58 Quality Adjusted Life Years, 28,052 Euros), these results indicate that PAD screening and treatment is a dominant strategy. The cost effectiveness acceptability curves show 88% probability of PAD screening being cost effective at the Willingness To Pay (WTP) threshold of 40000 Euros. In a scenario analysis using clopidogrel as an alternative anti-platelet drug, PAD screening strategy remained dominant. This decision analysis suggests that targeted ABI screening and consequent secondary prevention of cardiovascular events using low dose aspirin or clopidogrel in the identified patients is a cost-effective strategy. Implementation of targeted PAD screening and subsequent treatment in primary care practices and in public health programs is likely to improve the societal health and to save health care costs by reducing catastrophic cardiovascular events.

Evaluative conditioning (EC) is defined as the change in the evaluation of a conditioned stimulus (CS) because of its pairing with a valenced unconditioned stimulus (US). Counter to views that EC is the product of automatic learning processes, recent research has revealed various characteristics of nonautomatic processing in EC. The current research investigated the controllability of EC by testing the effectiveness of 3 emotion-focused strategies in preventing the acquisition of conditioned preferences: (a) suppression of emotional reactions to the US, (b) reappraisal of the valence of the US, and (c) facial blocking of emotional responses. Although all 3 strategies reduced EC effects on self-reported evaluations by impairing recollective memory for CS-US pairings, they were ineffective in reducing EC effects on an evaluative priming measure. Regardless of the measure, effective control did not depend on the level of arousal elicited by the US. The results suggest that the 3 strategies can influence deliberate CS evaluations through memory-related processes, but they are ineffective in reducing EC effects on spontaneous evaluative responses. Implications for mental process theories of EC are discussed. (c) 2015 APA, all rights reserved).
Cost-effectiveness of cervical cancer screening with primary human papillomavirus testing in Norway
Burger, E A; Ortendahl, J D; Sy, S; Kristiansen, I S; Kim, J J
2012-01-01
Background: New screening technologies and vaccination against human papillomavirus (HPV), the necessary cause of cervical cancer, may impact optimal approaches to prevent cervical cancer. We evaluated the cost-effectiveness of alternative screening strategies to inform cervical cancer prevention guidelines in Norway. Methods: We leveraged the primary epidemiologic and economic data from Norway to contextualise a simulation model of HPV-induced cervical cancer. The current cytology-only screening was compared with strategies involving cytology at younger ages and primary HPV-based screening at older ages (31/34+ years), an option being actively deliberated by the Norwegian government. We varied the switch-age, screening interval, and triage strategies for women with HPV-positive results. Uncertainty was evaluated in sensitivity analysis. Results: Current cytology-only screening was less effective and more costly than strategies that involve switching to primary HPV testing in older ages. For unvaccinated women, switching at age 34 years to primary HPV testing every 4 years was optimal given the Norwegian cost-effectiveness threshold ($83 000 per year of life saved). For vaccinated women, a 6-year screening interval was cost-effective. When we considered a wider range of strategies, we found that an earlier switch to HPV testing (at age 31 years) may be preferred. Conclusions: Strategies involving a switch to HPV testing for primary screening in older women is expected to be cost-effective compared with current recommendations in Norway. PMID:22441643

This article considers the implications for prevention science of recent advances in research on family poverty and children's mental, emotional, and behavioral health. First, we describe definitions of poverty and the conceptual and empirical challenges to estimating the causal effects of poverty on children's mental, emotional, and behavioral health. Second, we offer a conceptual framework that incorporates selection processes that affect who becomes poor as well as mechanisms through which poverty appears to influence child and youth mental health. Third, we use this conceptual framework to selectively review the growing literatures on the mechanisms through which family poverty influences the mental, emotional, and behavioral health of children. We illustrate how a better understanding of the mechanisms of effect by which poverty impacts children's mental, emotional, and behavioral health is valuable in designing effective preventive interventions for those in poverty. Fourth, we describe strategies to directly reduce poverty and the implications of these strategies for prevention. This article is one of three in a special section (see also Biglan, Flay, Embry, & Sandler, 2012; Muñoz, Beardslee, & Leykin, 2012) representing an elaboration on a theme for prevention science developed by the 2009 report of the National Research Council and Institute of Medicine.
Primordial Prevention of Cardiometabolic Risk in Childhood.
Tanrikulu, Meryem A; Agirbasli, Mehmet; Berenson, Gerald
2017-01-01
Fetal life and childhood are important in the development of cardiometabolic risk and later clinical disease of atherosclerosis, hypertension and diabetes mellitus. Molecular and environmental conditions leading to cardiometabolic risk in early life bring us a challenge to develop effective prevention and intervention strategies to reduce cardiovascular (CV) risk in children and later disease. It is important that prevention strategies begin at an early age to reduce future CV morbidity and mortality. Pioneering work from longitudinal studies such as Bogalusa Heart Study (BHS), the Finnish Youth Study and other programs provide an awareness of the need for public and health services to begin primordial prevention. The impending CV risk beginning in childhood has a significant socioeconomic burden. Directions to achieve primordial prevention of cardiometabolic risk in children have been developed by prior longitudinal studies. Based on those studies that show risk factors in childhood as precursors of adult CV risk, implementation of primordial prevention will have effects at broad levels. Considering the epidemic of obesity, the high prevalence of hypertension and cardiometabolic risk, prevention early in life is valuable. Comprehensive health education, such as 'Health Ahead/Heart Smart', for all elementary school age children is one approach to begin primordial prevention and can be included in public education beginning in kindergarten along with the traditional education subject matter.
Pressure ulcer prevention in frail older people.
Barry, Maree; Nugent, Linda
2015-12-16
Pressure ulcers are painful and cause discomfort, have a negative effect on quality of life, and are costly to treat. The incidence and severity of preventable pressure ulcers is an important indicator of quality of care; it is essential that healthcare providers monitor prevalence and incidence rates to ensure that care strategies implemented are effective. Frail older people are at increased risk of developing pressure ulcers. This article discusses the complexities of preventing pressure ulcers in frail older people and emphasises the importance of structured educational programmes that incorporate effective clinical leadership and multidisciplinary teamwork.

Background Tobacco consumption contributes significantly to the global burden of disease. The prevalence of smoking is estimated to be increasing in many low-income countries, including Tanzania, especially among women and youth. Even so, the implementation of tobacco control measures has been discouraging in the country. Efforts to foster investment in tobacco control are hindered by lack of evidence on what works and at what cost. Aims We aim to estimate the cost and cost-effectiveness of population-based tobacco control strategies in the prevention of cardiovascular diseases (CVD) in Tanzania. Materials and methods A cost-effectiveness analysis was performed using an Excel-based Markov model, from a governmental perspective. We employed an ingredient approach and step-down methodologies in the costing exercise following a government perspective. Epidemiological data and efficacy inputs were derived from the literature. We used disability-adjusted life years (DALYs) averted as the outcome measure. A probabilistic sensitivity analysis was carried out with Ersatz to incorporate uncertainties in the model parameters. Results Our model results showed that all five tobacco control strategies were very cost-effective since they fell below the ceiling ratio of one GDP per capita suggested by the WHO. Increase in tobacco taxes was the most cost-effective strategy, while a workplace smoking ban was the least cost-effective option, with a cost-effectiveness ratio of US$5 and US$267, respectively. Conclusions Even though all five interventions are deemed very cost-effective in the prevention of CVD in Tanzania, more research on budget impact analysis is required to further assess the government’s ability to implement these interventions.

Objective Identify risk factors for fighting, factors that protect against fighting, and strategies to prevent fighting, among adolescents who fight and those uninvolved in fighting. Methods Focus groups were conducted with middle and high-school students, stratified by fighting (fighter/non-fighter) status, race/ethnicity, and gender. Groups were audiotaped, transcribed, and analyzed using margin coding and thematic content analysis. Themes were independently identified by three coders; disagreements were resolved by consensus. Results The 65 participants in the 12 focus groups were 13–17 years old. Reasons for fighting include self-defense, to gain/maintain respect, or due to anger; having goals for the future is protective. Non-fighters state that their parents condone fighting only when physically attacked, and teach adolescents strategies to avoid fighting. Fighters describe mixed messages from parents, and pro-fighting attitudes and modeling of aggressive behavior among some family members. Non-fighters avoid fighting by ignoring insults or walking away. Fighters feel unable to use nonviolent conflict-resolution methods effectively. Peers may instigate or encourage fights. Suggested prevention strategies include anger-management and conflict-resolution programs, relationships with caring adults, and physicians counseling youth about the consequences of fighting. Conclusions Non-fighters use various strategies to avoid fighting, whereas fighters are aware of few alternatives to fighting. Conflicting parental messages about fighting may enhance the likelihood of fighting. Physicians can counsel youth about the negative consequences of fighting. Interventions that teach anger management and conflict resolution, promote adolescent self-efficacy for using non-violent strategies, and address parental attitudes about fighting may be effective in preventing fighting.

2012-01-01
To minimize industrial accidents, it's critical to evaluate a firm's priorities for prevention factors and strategies since such evaluation provides decisive information for preventing industrial accidents and maintaining safety management. Therefore, this paper proposes the evaluation of priorities through statistical testing of prevention factors with a cause analysis in a cause and effect model. A priority matrix criterion is proposed to apply the ranking and for the objectivity of questionnaire results. This paper used regression method (RA), exponential smoothing method (ESM), double exponential smoothing method (DESM), autoregressive integrated moving average (ARIMA) model and proposed analytical function method (PAFM) to analyze trends of accident data that will lead to an accurate prediction. This paper standardized the questionnaire results of workers and managers in manufacturing and construction companies with less than 300 employees, located in the central Korean metropolitan areas where fatal accidents have occurred. Finally, a strategy was provided to construct safety management for the third industrial accident prevention plan and a forecasting method for occupational accident rates and fatality rates for occupational accidents per 10,000 people.

Although a large proportion of healthcare-associated infections are avoidable, healthcare workers do not always practice evidence-based preventive strategies. Marketing technologies might help to improve patient safety. This article presents the basic principles of marketing and its potential use to promote good infection control practices. The marketing mix (Product, Price, Place, and Promotion) should be taken into account to induce behaviour change. By placing the emphasis on the perceived "profits" for healthcare workers the approach might lose its moral aspect and gain in effectiveness. VigiGerme, a non-commercial registered trademark, applies social marketing techniques to infection control and prevention.

This report represents the consensus of a panel of representatives from psychiatry, psychology, pharmacology, epidemiology, internal medicine, and the general public regarding the use of pharmacologic agents to prevent recurrences of mood disorders. The panel concluded that recurrent mood disorders, which have a high prevalence and serious consequences, are underdiagnosed and undertreated. Applying appropriate strategies to the management and use of pharmacologic agents will enhance the likelihood of compliance and the prevention of recurrence with a minimum of bothersome side effects. Such strategies should be used within the context of a supportive relationship among doctor, patient, and family.
Cancer Prevention in HIV-Infected Populations

2016-01-01
People living with human immunodeficiency virus (HIV) are living longer since the advent of effective combined antiretroviral therapy (cART). While cART substantially decreases the risk of developing some cancers, HIV-infected individuals remain at high risk for Kaposi sarcoma, lymphoma and several solid tumors. Currently HIV-infected patients represent an aging group, and malignancies have become a leading cause of morbidity and mortality. Tailored cancer-prevention strategies are needed for this population. In this review we describe the etiologic agents and pathogenesis of common malignancies in the setting of HIV, as well as current evidence for cancer prevention strategies and screening programs.

To investigate the effects of a multifaceted implementation strategy on behaviour, behavioural determinants, knowledge and awareness of healthcare workers regarding the use of recommendations to prevent hand eczema. The Hands4U study is a randomised controlled trial. A total of 48 departments (n=1649 workers) were randomly allocated to the multifaceted implementation strategy or the control group (minimal implementation strategy). Within the departments designated to the multifaceted implementation strategy, participatory working groups were set up to enhance the implementation of the recommendations for hand eczema. In addition, working group members were trained to become role models, and an education session was given within the department. Outcome measures were awareness, knowledge, receiving information, behaviour and behavioural determinants. Data were collected at baseline, with a 3- and 6-month follow-up. Statistically significant effects were found after 6 months for awareness (OR 6.30; 95% CI 3.41 to 11.63), knowledge (B 0.74; 95% CI 0.54 to 0.95), receiving information (OR 9.81; 95% CI 5.60 to 17.18), washing hands (B -0.40; 95% -0.51 to -0.29), use of moisturiser (B 0.29; 95% CI 0.20 to 0.38), cotton under gloves (OR 3.94; 95% CI 2.04 to 7.60) and the overall compliance measure (B 0.14; 95% CI 0.02 to 0.26), as a result of the multifaceted implementation strategy. No effects were found for behavioural determinants. The multifaceted implementation strategy can be used in healthcare settings to enhance the implementation of recommendations for the prevention of hand eczema. NTR2812.

Evolving Use of Natriuretic Peptides as Part of Strategies for Heart Failure Prevention.
McDonald, Ken; Wilkinson, Mark
2017-01-01
Heart failure (HF) remains one of the major cardiovascular challenges to the Western world. Once established, HF is characterized by compromised life expectancy and quality of life with considerable dependence on hospital care for episodic clinical deterioration. Much is understood about the risk factors that predispose to the development of HF. With such a broad range of factors, it is clear that there is a large population at risk, potentially in excess of 25% of the adult population. Therein lies the major challenge at the outset of our efforts to prevent HF. With such a large population at risk, how do we develop an effective prevention strategy? HF prevention requires a multimodal approach. In this review, we focus primarily on the role of natriuretic peptide (NP) as a tool in a prevention strategy. Prevention of HF is a major public health challenge, underlined by the concerning epidemiological trends, the associated costs, and the continued difficulty to find effective therapies for the growing number of patients with preserved systolic function HF. Population-based approaches focusing on lifestyle and risk factor control have made some impact but not to a satisfactory level and also tend to result in a uniform approach across a population with different risk profiles. Individualizing risk is therefore required, with emerging data indicating that NP-guided risk stratification and intervention can reduce downstream incident HF and other cardiovascular events. © 2016 American Association for Clinical Chemistry.
Using Social Media to Target Cancer Prevention in Young Adults: Viewpoint.
Sarkar, Urmimala; Le, Gem M; Lyles, Courtney R; Ramo, Danielle; Linos, Eleni; Bibbins-Domingo, Kirsten
2018-06-05
Focusing on primary cancer prevention can reduce its incidence. Changing health behaviors is critical to cancer prevention. Modifiable cancer risk factors include lifestyle behaviors related to vaccination, physical activity, weight control and maintenance, alcohol consumption, and tobacco use. These health habits are often formed in young adulthood, a life stage which currently intersects with the growing population of digital natives whose childhood occurred in the internet era. Social media is a critical communication medium to reach this population of digital natives. Using a life course perspective, the purpose of this viewpoint paper is to describe the current landscape of nascent research using social media to target cancer prevention efforts in young adults and propose future directions to strengthen the scientific knowledge supporting social media strategies to promote cancer prevention behaviors. Leveraging social media as a health promotion tool is a promising strategy to impact modifiable behavioral risk factors for cancer and warrants further research on developing effective communication strategies in young adults to prevent cancer in the future generations. ©Urmimala Sarkar, Gem M Le, Courtney R Lyles, Danielle Ramo, Eleni Linos, Kirsten Bibbins-Domingo.

Cetinel, Sibel; Montemagno, Carlo
2015-01-01
The purpose of this article was to review recent advances in the applications of nanotechnology in cataract treatment and prevention strategies. A literature review on the use of nanotechnology for the prevention and treatment of cataract was done. Research articles about nanotechnology-based treatments and prevention technologies for cataract were searched on Web of Science, and the most recent advances were reported. Nonsteroid anti-inflammatory drugs, natural antioxidants, biologic and chemical chaperones, and chaperones such as molecules have found great application in preventing and treating cataracts. Current scientific research on new treatment strategies, which focuses on the biochemical basis of the disease, will likely result in new anticataract agents. However, none of the drug formulations will be approved for use unless efficient delivery is promised. Nanoparticle engineering together with biomimetic strategies enable the development of next-generation, more efficient, less complex, and personalized treatments. The only currently available treatment for cataracts, surgical replacement of the opacified lens, is not an easily accessible option in developing countries. New treatment strategies based on topical drugs would enable treatment to reach massive populations facing the threat of blindness and more effectively deal with the postsurgical complications. Nanotechnology plays a key role in improving drug delivery systems with enhanced controlled release, targeted delivery, and bioavailability to overcome diffusion limitations in the eye.

Recent research has suggested that women who experience preterm delivery (PTD) may be identified earlier in pregnancy and before onset of symptoms. Interventions commenced at this earlier asymptomatic stage may offer an opportunity to prevent PTD or lengthen gestation sufficiently to reduce adverse perinatal outcome. Our objective was to examine the evidence that supports or refutes this approach to preventing PTD. We therefore conducted a systematic search and critical appraisal of the identified literature. We found evidence that introducing screening-preventative strategies for asymptomatic pregnancies may reduce the rate of PTD. Evidence for screening and selective treatment exists for: asymptomatic bacteriuria; bacterial vaginosis in low-risk population groups; elective cervical cerclage in high-risk pregnancies; indicated cervical cerclage in women with short cervical length on ultrasound; prophylactic progesterone supplementation in high-risk pregnancies, and smoking cessation. However, for most other strategies, such as increased antenatal attendance, or routine administration of prophylactic micronutrients, the evidence is inconsistent and conflicting. Information on neonatal outcomes apart from PTD (such as serious neonatal morbidity and mortality) was found to be lacking in most studies. It was therefore not possible to establish whether preventing PTD or prolonging gestation would correlate to improved perinatal outcome, and this lessened the potential clinical usefulness of any proposed preventative strategy. No studies were found that evaluated the effectiveness of combining screening-preventative strategies. The review concludes with a suggested an antenatal management plan designed to prevent PTD based on current practice and the evidence presented in this article.
A strategy for cancer prevention and control research*

Cancer is an important cause of morbidity and mortality in industrial countries. Recently changes in life-style and the environment in developing countries have coincided with increases in the incidence of certain cancers which might be related to these factors. A strategy for the prevention of all such cancers is presented, which involves research in a sequence of five phases to identify suitable interventions and to confirm their effectiveness in population studies, prior to their application on a nationwide scale.

Indigenous communities often face disproportionate challenges across a variety of health domains, and effective prevention strategies are sorely needed. Unfortunately, evidence is scant regarding what approaches are effective for these communities. A common approach is to take an evidence-based practice or program with documented effectiveness in other populations and implement it with Indigenous populations. While a science of intervention adaptation is emerging, there remains little guidance on processes for adaptation that strategically leverage both existing scientific evidence and Indigenous prevention strategies. In this paper, two case studies illustrate promising practices for adaptation, documenting the approaches of two research teams funded under the National Institutes of Health's initiative to support Intervention Research to Improve Native American Health (IRINAH). These teams worked with distinct Indigenous populations in the USA and Canada to culturally adapt the same prevention program, the Iowa Strengthening Families Program for Parents and Youth 10-14. The approaches of these two teams and the programs that resulted are compared and contrasted, and critical elements of adaptation in partnership with Indigenous communities are discussed.
Cost considerations in implementing a screening and surveillance strategy for Barrett's oesophagus.
Inadomi, John M
2015-02-01
There is increasing concern over the rising costs of healthcare leading to debate regarding the use of resources to implement preventive strategies. Oesophageal adenocarcinoma and its precursor, Barrett's oesophagus provides an excellent opportunity to highlight this issue since cancer is uncommon even among individuals with documented Barrett's oesophagus. This review provides a brief introduction to economic analysis in healthcare and summarizes published studies of the cost-effectiveness of strategies to reduce mortality from cancer. Current best estimates highlight the cost-effectiveness of endoscopic ablation among patients with Barrett's oesophagus and high-grade dysplasia and the low cost-effectiveness of ablation among patients without dysplasia. The cost-effectiveness of ablation among patients with Barrett's and low-grade dysplasia is poorly defined due to the ambiguity of diagnosing dysplasia, the unknown risk of cancer among patients with low-grade dysplasia, and the uncertain durability of ablation to maintain remission from metaplasia and dysplasia and prevent cancer.

We examined intervention effectiveness of strategies to prevent image- and performance-enhancing drug use. Comprehensive searches identified 14 interventions that met review inclusion criteria. Interventions were predominantly educational and delivered within school sport settings, but targeted a wide range of mediating factors. Identification of effective components was limited across studies by brief or imprecise descriptions of intervention content, lack of behavioural outcome measures and short-term follow-up times. However, studies with components in addition to information provision may be more promising. Interventions outside of sport settings are required to reflect the transition of this form of substance use to the general population.
Empirically Based Strategies for Preventing Juvenile Delinquency.
Pardini, Dustin
2016-04-01
Juvenile crime is a serious public health problem that results in significant emotional and financial costs for victims and society. Using etiologic models as a guide, multiple interventions have been developed to target risk factors thought to perpetuate the emergence and persistence of delinquent behavior. Evidence suggests that the most effective interventions tend to have well-defined treatment protocols, focus on therapeutic approaches as opposed to external control techniques, and use multimodal cognitive-behavioral treatment strategies. Moving forward, there is a need to develop effective policies and procedures that promote the widespread adoption of evidence-based delinquency prevention practices across multiple settings.

Preventing infective complications relating to induced abortion.
Mary, Nirmala; Mahmood, Tahir A
2010-08-01
Infective complications following induced abortions are still a common cause of morbidity and mortality. This review focusses on defining the strategies to improve care of women seeking an induced abortion and to reduce infective complications. We have considered the evidence for screening and cost-effectiveness for antibiotic prophylaxis. Current evidence suggests that treating all women with prophylactic antibiotics in preference to screening and treating is the most cost-effective way of reducing infective complications following induced abortions. The final strategy to prevent infective complications should be individualized for each region/area depending on the prevalence of organisms causing pelvic infections and the resources available. 2010 Elsevier Ltd.

A review of 'green' strategies to prevent or mitigate microbiologically influenced corrosion.
Little, Brenda; Lee, Jason; Ray, Richard
2007-01-01
Two approaches to control microbiologically influenced corrosion (MIC) have been developed that do not require the use of biocides. These strategies include the following: i) use of biofilms to inhibit or prevent corrosion, and ii) manipulation (removal or addition) of an electron acceptor, (e.g. oxygen, sulphate or nitrate) to influence the microbial population. In both approaches the composition of the microbial community is affected by small perturbations in the environment (e.g. temperature, nutrient concentration and flow) and the response of microorganisms cannot be predicted with certainty. The following sections will review the literature on the effectiveness of these environmentally friendly, "green," strategies for controlling MIC.

There are substantial differences between the costs of medical masks and N95 respirators. Cost-effectiveness analysis is required to assist decision-makers evaluating alternative healthcare worker (HCW) mask/respirator strategies. This study aims to compare the cost-effectiveness of N95 respirators and medical masks for protecting HCWs in Beijing, China. We developed a cost-effectiveness analysis model utilising efficacy and resource use data from two cluster randomised clinical trials assessing various mask/respirator strategies conducted in HCWs in Level 2 and 3 Beijing hospitals for the 2008-09 and 2009-10 influenza seasons. The main outcome measure was the incremental cost-effectiveness ratio (ICER) per clinical respiratory illness (CRI) case prevented. We used a societal perspective which included intervention costs, the healthcare costs of CRI in HCWs and absenteeism costs. The incremental cost to prevent a CRI case with continuous use of N95 respirators when compared to medical masks ranged from US $490-$1230 (approx. 3000-7600 RMB). One-way sensitivity analysis indicated that the CRI attack rate and intervention effectiveness had the greatest impact on cost-effectiveness. The determination of cost-effectiveness for mask/respirator strategies will depend on the willingness to pay to prevent a CRI case in a HCW, which will vary between countries. In the case of a highly pathogenic pandemic, respirator use in HCWs would likely be a cost-effective intervention.

Extensive water damage after major hurricanes and floods increases the likelihood of mold contamination in buildings. This report provides information on how to limit exposure to mold and how to identify and prevent mold-related health effects. Where uncertainties in scientific knowledge exist, practical applications designed to be protective of a person's health are presented. Evidence is included about assessing exposure, clean-up and prevention, personal protective equipment, health effects, and public health strategies and recommendations. The recommendations assume that, in the aftermath of major hurricanes or floods, buildings wet for <48 hours will generally support visible and extensive mold growth and should be remediated, and excessive exposure to mold-contaminated materials can cause adverse health effects in susceptible persons regardless of the type of mold or the extent of contamination. For the majority of persons, undisturbed mold is not a substantial health hazard. Mold is a greater hazard for persons with conditions such as impaired host defenses or mold allergies. To prevent exposure that could result in adverse health effects from disturbed mold, persons should 1) avoid areas where mold contamination is obvious; 2) use environmental controls; 3) use personal protective equipment; and 4) keep hands, skin, and clothing clean and free from mold-contaminated dust. Clinical evaluation of suspected mold-related illness should follow conventional clinical guidelines. In addition, in the aftermath of extensive flooding, health-care providers should be watchful for unusual mold-related diseases. The development of a public health surveillance strategy among persons repopulating areas after extensive flooding is recommended to assess potential health effects and the effectiveness of prevention efforts. Such a surveillance program will help CDC and state and local public health officials refine the guidelines for exposure avoidance, personal protection, and clean-up and assist health departments to identify unrecognized hazards.
Economic optimization of a global strategy to address the pandemic threat.

Emerging pandemics threaten global health and economies and are increasing in frequency. Globally coordinated strategies to combat pandemics, similar to current strategies that address climate change, are largely adaptive, in that they attempt to reduce the impact of a pathogen after it has emerged. However, like climate change, mitigation strategies have been developed that include programs to reduce the underlying drivers of pandemics, particularly animal-to-human disease transmission. Here, we use real options economic modeling of current globally coordinated adaptation strategies for pandemic prevention. We show that they would be optimally implemented within 27 y to reduce the annual rise of emerging infectious disease events by 50% at an estimated one-time cost of approximately $343.7 billion. We then analyze World Bank data on multilateral "One Health" pandemic mitigation programs. We find that, because most pandemics have animal origins, mitigation is a more cost-effective policy than business-as-usual adaptation programs, saving between $344.0.7 billion and $360.3 billion over the next 100 y if implemented today. We conclude that globally coordinated pandemic prevention policies need to be enacted urgently to be optimally effective and that strategies to mitigate pandemics by reducing the impact of their underlying drivers are likely to be more effective than business as usual.

Background Lost productivity represents a considerable portion of the total economic burden of colorectal cancer (CRC), but cost-effectiveness studies of CRC prevention and control have not included these costs and therefore underestimate potential savings from CRC prevention and control. Purpose To use microsimulation modeling study to estimate and project productivity costs of CRC and to model the savings from four approaches to reducing CRC incidence and mortality: risk factor reduction, improved screening, improved treatment, and a simultaneous approach where all three strategies are implemented. Methods A model was developed to project productivity losses from CRC using the U.S. population with CRC incidence and mortality projected through the year 2020. Outcome measures were CRC mortality, morbidity, and productivity savings. Results With 2005 levels in risk factors, screening, and treatment, 48,748 CRC deaths occurred in 2010, amounting to $21 billion of lost productivity. Using prevention and treatment strategies simultaneously, 3586 deaths could have been avoided in 2010, leading to a savings of $1.4 billion. Cumulatively, by 2020, simultaneous strategies that reduce risk factors and increase screening and treatment could result in 101,353 deaths avoided and $33.9 billion in savings in reduced productivity loss. Improved screening rates alone led to nearly $14.7 billion in savings between 2005 and 2020, followed by risk factor reduction ($12.4 billion) and improved treatment ($8.4 billion). Conclusions The savings in productivity loss from strategies to reduce CRC incidence and mortality are substantial, providing evidence that CRC prevention and control strategies are likely to be cost-saving.

Overview of gastrointestinal cancer prevention in Asia.
Park, Jong-Min; Lee, Ho-Jae; Yoo, Jun Hwan; Ko, Weon Jin; Cho, Joo Young; Hahm, Ki Baik
2015-12-01
"War on cancer" was declared through the National Cancer Act by President Richard Nixon in 1971, but cancer statistics from the American Cancer Society and other sources indicated the failure of this war, suggesting instead focus on the message that a "prevention strategy" might be much more effective than cancer treatment. While cancer statistics notoriously showed sharp increases in incidence as well as in mortality concurrent with economic growth in Asia, fortunately Asian countries benefit from plentiful resources of natural compounds, which can prevent cancer. Just like cancer chemotherapeutics targeted to kill cancer cells in Western countries, natural agents activating molecular mechanisms for cancer prevention, reversion of premalignant tumors, and even ablation of cancer stem cells, are very abundant in Asia. Currently, these natural agents are under very active investigations targeting the hallmarks of cancer prevention, including selective induction of apoptosis in cancer cells, suppression of growth factors or their signaling, suppression of cell proliferation and of cancer-promoting angiogenesis, induction of mesenchymal-epithelial transition, and disruption of the tumor microenvironment, developing promising cancer preventive agents. However, Asia is the most populous continent in the world and some Asian countries do not have the resources to implement cancer screening programs for early detection or treatment. In addition, despite the excellent cancer preventive screening strategies in some Asian countries, well-designed clinical trials for cancer prevention are somewhat delayed compared to Western countries. In this review article, several phytochemicals/phytoceuticals produced and studied in different Asian countries will be introduced, including Korean red ginseng (pride of Korea), curcumin (Indian spice for life), black or green tea (popular in Japan/Sri Lanka), genistein from tofu (famous Chinese food), diallylsulfide or S-allylcysteine (garlic, popularly consumed as a food ingredient in many Asian countries), capsaicin, 6-gingerol, flavopiridol, and silymarin (abundant in various Asian foods). Whereas in Western countries cancer chemotherapeutics involve strategies not only to block the growth of the primary tumor, but also to inhibit its progression to metastatic disease, the endless pursuit of effective agents for cancer prevention may be a unique and featured strategy in Asia. More active efforts for clinical application of these principles should be supported. Copyright © 2015 Elsevier Ltd. All rights reserved.
Population-based dietary approaches for the prevention of noncommunicable diseases.
Somasundaram, Noel P; Kalupahana, Nishan Sudheera
2016-04-01
As the incidence of noncommunicable diseases such as diabetes continues to rise at an alarming rate in South-East Asia, it is imperative that urgent and population-wide strategies are adopted. The most important contributors to the rise in noncommunicable disease are a rise in mean caloric intake and a decrease in physical activity. The evidence for population-based dietary approaches to counter these factors is reviewed. Several structural and cohesive interdepartmental coordination efforts are required for effective implementation of prevention strategies. Since low- and middle-income countries may lack the frameworks for effective and integrated multi-stakeholder intervention, implementation of population-based dietary and physical-activity approaches may be delayed and may be too late for effective prevention in current at-risk cohorts. Evidence-based strategies to decrease energy intake and increase physical activity are now well established and their urgent adoption by Member States of the World Health Organization South-East Asia Region is essential. In the context of Sri Lanka, for example, it is recommended that the most effective and easy-to-implement interventions would be media campaigns, restrictions on advertisement of unhealthy foods, taxation of unhealthy foods, subsidies for production of healthy foods, and laws on nutrition labelling that introduce colour coding of packaged foods.

Cancer is the leading cause of death in Puerto Rico, suggesting a need for improved strategies, programs, and resources devoted to cancer prevention. Enhanced prevention needs in Puerto Rico were initially identified in pilot studies conducted by the Ponce School of Medicine (PSM) in collaboration with the H. Lee Moffitt Cancer Center (MCC). In the current study, we used community engagement to identify specific needs in cancer prevention and education and strategies to create culturally attuned, effective cancer prevention education programs. A total of 37 participants attended a community forum and were assigned to one of three discussion groups: patients/survivors (n = 14); family/caregivers (n = 11); or healthcare providers (n = 12). Most participants were women (73 %), over 35 years of age, and a majority were married (58 %) and had a university education (81 %). The sessions were recorded and transcribed and analyzed for key themes. Participants wanted improved awareness of cancer prevention in Puerto Rico and believed cancer prevention education should start early, ideally in elementary school. Participants also stressed the importance of creating partnerships with private and government agencies to coordinate educational efforts. Suggested strategies included outreach to communities with limited resources, incorporating the testimony of cancer survivors, and utilizing social media to disseminate cancer prevention information.
Prevention of Overweight and Obesity: How Effective is the Current Public Health Approach
Chan, Ruth S.M; Woo, Jean
2010-01-01
Obesity is a public health problem that has become epidemic worldwide. Substantial literature has emerged to show that overweight and obesity are major causes of co-morbidities, including type II diabetes, cardiovascular diseases, various cancers and other health problems, which can lead to further morbidity and mortality. The related health care costs are also substantial. Therefore, a public health approach to develop population-based strategies for the prevention of excess weight gain is of great importance. However, public health intervention programs have had limited success in tackling the rising prevalence of obesity. This paper reviews the definition of overweight and obesity and the variations with age and ethnicity; health consequences and factors contributing to the development of obesity; and critically reviews the effectiveness of current public health strategies for risk factor reduction and obesity prevention.

The aim of this study was to evaluate the efficacy of cognitive-behavioural therapy (CBT) in the prevention of post partum depression (PPD) in pregnant women at risk. PubMed, Medline, PsychInfo, Embase, and the Cochrane Library databases were searched from January 1991 to June 2011 to review studies on the efficacy of CBT in the prevention of PD. The literature analyzed recommends that depression in pregnancy requires an efficient management to provide mother's symptoms relief as well as to prevent PD. While several studies demonstrated the efficacy of CBT in the treatment of PD, only a few controlled studies focused on its efficacy in the prevention of PD in women identified at risk during pregnancy. The efficacy of CBT in preventing PD in pregnant women at risk is supported by only a few studies, presenting some methodological flaws. Better designed trials are needed to strongly support the efficacy of such psychotherapeutic preventive strategy in women at risk for PD.

Men are at greater risk than women of dying by suicide. One in eight will experience depression--a leading contributor to suicide--in their lifetime and men often delay seeking treatment. Previous research has focused on men's use of unhelpful coping strategies, with little emphasis on men's productive responses. The present study examines the positive strategies men use to prevent and manage depression. A national online survey investigated Australian men's use of positive strategies, including 26 strategies specifically nominated by men in a previous qualitative study. Data were collected regarding frequency of use or openness to using untried strategies, depression risk, depression symptoms, demographic factors, and other strategies suggested by men. Multivariate regression analyses explored relationships between regular use of strategies and other variables. In total, 465 men aged between 18 and 74 years participated. The mean number of strategies used was 16.8 (SD 4.1) for preventing depression and 15.1 (SD 5.1) for management. The top five prevention strategies used regularly were eating healthily (54.2 %), keeping busy (50.1 %), exercising (44.9 %), humour (41.1 %) and helping others (35.7 %). The top five strategies used for management were taking time out (35.7 %), rewarding myself (35.1 %), keeping busy (35.1 %), exercising (33.3 %) and spending time with a pet (32.7 %). With untried strategies, a majority (58 %) were open to maintaining a relationship with a mentor, and nearly half were open to using meditation, mindfulness or gratitude exercises, seeing a health professional, or setting goals. In multivariate analyses, lower depression risk as measured by the Male Depression Risk Scale was associated with regular use of self-care, achievement-based and cognitive strategies, while lower scores on the Patient Health Questionnaire-9 was associated with regular use of cognitive strategies. The results demonstrate that the men in the study currently use, and are open to using, a broad range of practical, social, emotional, cognitive and problem-solving strategies to maintain their mental health. This is significant for men in the community who may not be in contact with professional health services and would benefit from health messages promoting positive strategies as effective tools in the prevention and management of depression.

Education to improve health professionals' responses to suicide is considered an important suicide prevention strategy. However, the effectiveness of this approach for nurses is unclear. To systematically review the peer-reviewed literature regarding the effectiveness of suicide prevention education programs for nurses. Nine academic databases (CINAHL, Cochrane Reviews & Trials, Embase, Informit Health Collection, Joanna Briggs Institute, Medline, PsycINFO, Scopus, and Web of Science) were searched in November 2016, utilizing search terms related to suicide, education, and nurses, with no limits placed on publication date or study design. The search yielded 5,456 identified articles, 11 of which met the inclusion criteria. Studies were primarily quantitative (RCTs n = 3; quasi-experimental n = 6; qualitative n = 2), and involved nurses (range = 16-561) working in a diversity of settings, particularly hospitals (n = 9). Studies revealed positive changes in nurses' competence, knowledge, and attitudes associated with training over the short term. The heterogeneity of education programs and methodological weaknesses of included studies limit the conclusions drawn. There is a moderate body of evidence to support the effectiveness of suicide prevention education programs for nurses. Future research should examine longer-term changes in clinical practice and strategies for continuing education, with more rigorous study designs.
Strategies for improving safety performance in construction firms.
Alarcón, Luis Fernando; Acuña, Diego; Diethelm, Sven; Pellicer, Eugenio
2016-09-01
Over the years many prevention management practices have been implemented to prevent and mitigate accidents at the construction site. However, there is little evidence of the effectiveness of individual or combined practices used by companies to manage occupational health and safety issues. The authors selected a sample of 1180 construction firms and 221 individual practices applied in these companies to analyze their effectiveness reducing injury rates over a period of four years in Chile. Different methods were used to study this massive database including: visual analyses of graphical information, statistical analyses and classification techniques. Results showed that practices related to safety incentives and rewards are the most effective from the accident rate viewpoint, even though they are seldom used by companies; on the other hand, practices related to accidents and incidents investigation had a slight negative impact on the accident rate because they are frequently used as a reactive measure. In general, the higher the percentage of prevention practices implemented in a strategy, the lower the accident rate. However, the analysis of the combined effect of prevention practices indicated that the choice of the right combination of practices was more important than just the number of practices implemented.

Making the workplace a more effective site for prevention of noncommunicable diseases in adults.
Tryon, Katherine; Bolnick, Howard; Pomeranz, Jennifer L; Pronk, Nicolaas; Yach, Derek
2014-11-01
Efforts to realize the potential of disease prevention in the United States have fallen behind those of peer countries, and workplace disease prevention is a major gap. This article investigates the reasons for this gap. Literature review and expert discussions. Obstacles to effective use of workplace disease prevention include limited leadership and advocacy, poor alignment of financial incentives, limitations in research quality and investment, regulation that does not support evidence-based practice, and a dearth of community-employer partnerships. We make recommendations to address these obstacles, such as the inclusion of health metrics in corporate reporting, making the workplace a central component of the strategy to combat the effect of noncommunicable diseases, and linking prevention directly benefit businesses' bottom lines.

To test the effectiveness of a central venous catheter (CVC) insertion strategy and a hand hygiene (HH) improvement strategy to prevent central venous catheter-related bloodstream infections (CRBSI) in European intensive care units (ICUs), measuring both process and outcome indicators. Adult ICUs from 14 hospitals in 11 European countries participated in this stepped-wedge cluster randomised controlled multicentre intervention study. After a 6 month baseline, three hospitals were randomised to one of three interventions every quarter: (1) CVC insertion strategy (CVCi); (2) HH promotion strategy (HHi); and (3) both interventions combined (COMBi). Primary outcome was prospective CRBSI incidence density. Secondary outcomes were a CVC insertion score and HH compliance. Overall 25,348 patients with 35,831 CVCs were included. CRBSI incidence density decreased from 2.4/1000 CVC-days at baseline to 0.9/1000 (p < 0.0001). When adjusted for patient and CVC characteristics all three interventions significantly reduced CRBSI incidence density. When additionally adjusted for the baseline decreasing trend, the HHi and COMBi arms were still effective. CVC insertion scores and HH compliance increased significantly with all three interventions. This study demonstrates that multimodal prevention strategies aiming at improving CVC insertion practice and HH reduce CRBSI in diverse European ICUs. Compliance explained CRBSI reduction and future quality improvement studies should encourage measuring process indicators.
The use of H2 antagonists in treating and preventing NSAID-induced mucosal damage.
Tuskey, Anne; Peura, David
2013-01-01
Pain affects the quality of life for millions of individuals and is a major reason for healthcare utilization. As populations age, medical personnel will need to manage more and more patients suffering from pain associated with degenerative and inflammatory musculoskeletal disorders. Nonsteroidal anti-inflammatory drugs (NSAIDs) are an effective treatment for both acute and chronic musculoskeletal pain; however, their use is associated with potentially significant gastrointestinal (GI) toxicity. Guidelines suggest various strategies to prevent problems in those at risk for NSAID-associated GI complications. In this article, we review the data supporting one such strategy - the use of histamine type-2 receptor antagonists (H2RAs) - for the prevention of GI adverse events in NSAID users. Older studies suggest that high-dose H2RAs are effective in preventing upper GI ulcers and dyspepsia. This suggestion was recently confirmed during clinical trials with a new ibuprofen/famotidine combination that reduced the risk of ulcers by 50% compared with ibuprofen alone.

Guidelines suggest various strategies to prevent problems in those at risk for NSAID-associated GI complications. In this article, we review the data supporting one such strategy - the use of histamine type-2 receptor antagonists (H2RAs) - for the prevention of GI adverse events in NSAID users. Older studies suggest that high-dose H2RAs are effective in preventing upper GI ulcers and dyspepsia. This suggestion was recently confirmed during clinical trials with a new ibuprofen/famotidine combination that reduced the risk of ulcers by 50% compared with ibuprofen alone. PMID:24267478
Antiretroviral Therapy for the Prevention of HIV Transmission: What Will It Take?
McNairy, Margaret L.; El-Sadr, Wafaa M.
2014-01-01
The evidence in support of use of antiretroviral therapy (ART) for prevention of human immunodeficiency virus (HIV) transmission is encouraging and has stimulated optimism for achieving a dramatic change in the trajectory of the HIV epidemic. Yet, there are substantial challenges that, if not addressed, could be the Achilles’ heel for this concept. These challenges require strengthening every step of the HIV care continuum, including expansion of HIV testing to reach all those with HIV infection, effective linkage to and retention in care, timely initiation of ART, and high levels of treatment adherence with viral load suppression. Also important is the identification of individuals with acute HIV infection whose contribution to HIV transmission may be substantial. Implementation research is needed to identify strategies that address these challenges and to determine the efficacy of ART for prevention in key populations as well as to evaluate the effectiveness of combination strategies for HIV prevention at the population level.

Preventing Rehospitalization through effective home health nursing care.
Vasquez, Monica S
2009-01-01
To identify strategies to improve patient outcomes and prevent rehospitalizations in home healthcare. PRIMARY PRACTICE SETTINGS(S): Primarily for home healthcare but can also be a tool for all other fields in nursing. Through team collaboration and the proper resources, patient outcomes can improve and be cost-effective for home healthcare agencies despite the changes implemented after the Medicare change in payment for services, the prospective payment system. The main goal for home healthcare is to improve patient outcomes. Nurses experienced in case management can devise creative strategies to ensure patient outcomes are met in a cost-effective manner. With continuous changes in reimbursement and payment incentives, case managers in every level of care must know about, and be responsible for, fiscal initiatives.

Transcatheter left atrial appendage occlusion (LAAO) is a promising therapy for stroke prophylaxis in non-valvular atrial fibrillation (NVAF) but its cost-effectiveness remains understudied. This study evaluated the cost-effectiveness of LAAO for stroke prophylaxis in NVAF. A Markov decision analytic model was used to compare the cost-effectiveness of LAAO with 7 pharmacological strategies: aspirin alone, clopidogrel plus aspirin, warfarin, dabigatran 110 mg, dabigatran 150 mg, apixaban, and rivaroxaban. Outcome measures included quality-adjusted life years (QALYs), lifetime costs and incremental cost-effectiveness ratios (ICERs). Base-case data were derived from ACTIVE, RE-LY, ARISTOTLE, ROCKET-AF, PROTECT-AF and PREVAIL trials. One-way sensitivity analysis varied by CHADS2 score, HAS-BLED score, time horizons, and LAAO costs; and probabilistic sensitivity analysis using 10,000 Monte Carlo simulations was conducted to assess parameter uncertainty. LAAO was considered cost-effective compared with aspirin, clopidogrel plus aspirin, and warfarin, with ICER of US$5,115, $2,447, and $6,298 per QALY gained, respectively. LAAO was dominant (i.e. less costly but more effective) compared to other strategies. Sensitivity analysis demonstrated favorable ICERs of LAAO against other strategies in varied CHADS2 score, HAS-BLED score, time horizons (5 to 15 years) and LAAO costs. LAAO was cost-effective in 86.24 % of 10,000 simulations using a threshold of US$50,000/QALY. Transcatheter LAAO is cost-effective for prevention of stroke in NVAF compared with 7 pharmacological strategies. The transcatheter left atrial appendage occlusion (LAAO) is considered cost-effective against the standard 7 oral pharmacological strategies including acetylsalicylic acid (ASA) alone, clopidogrel plus ASA, warfarin, dabigatran 110 mg, dabigatran 150 mg, apixaban, and rivaroxaban for stroke prophylaxis in non-valvular atrial fibrillation management.

Peer education remains a popular strategy for health promotion and prevention, but evidence of its effectiveness is still limited. This article presents a systematic review of peer education interventions in the European Union that were published between January 1999 and May 2010. The objective of the review is to determine the effectiveness of peer education programs for human immunodeficiency virus (HIV) prevention, adolescent pregnancy prevention and promotion of sexual health among young people. Standardized methods of searching and data extraction were utilized and five studies were identified. Although a few statistically significant and non-significant changes were observed in the studies, it is concluded that, overall, when compared to standard practice or no intervention, there is no clear evidence of the effectiveness of peer education concerning HIV prevention, adolescent pregnancy prevention and sexual health promotion for young people in the member countries of the European Union. Further research is needed to determine factors that contribute to program effectiveness.

We systematically searched 9 biomedical and social science databases (1980–2012) for primary and secondary interventions that prevented or reduced 2 or more adolescent health risk behaviors (tobacco use, alcohol use, illicit drug use, risky sexual behavior, aggressive acts). We identified 44 randomized controlled trials of universal or selective interventions and were effective for multiple health risk behaviors. Most were school based, conducted in the United States, and effective for multiple forms of substance use. Effects were small, in line with findings for other universal prevention programs. In some studies, effects for more than 1 health risk behavior only emerged at long-term follow-up. Integrated prevention programs are feasible and effective and may be more efficient than discrete prevention strategies. PMID:24625172

Background The HIV/AIDS epidemic has been strongly felt in Hispanic/Latino communities. Estimates of AIDS prevalence among Latinos in the US reveal that just nine States and the Commonwealth of Puerto Rico account for 89% of the Latinos living with AIDS in 2004. Previous research reveals social and cultural factors play an important role in HIV prevention. Methods Four focus groups were conducted, with 39 women, ages 21–67, participating in the discussions. The objectives of this research were to assess knowledge regarding HIV transmission among women living in low-income households, to ascertain barriers to safe sex in this population, and to elicit opinions about effective prevention strategies. Results Our results suggest that participants recognized HIV/AIDS modes of transmission and risk behaviors, as well as their barriers to practicing safe sex. They identified promiscuity, unprotected sex, infidelity, drug and alcohol use, and sharing syringes as behaviors which would place them at risk of HIV/AIDS transmission. They specifically identified lack of negotiating skills, fear of sexual violence, partner refusal to use condoms, and lack of control over their partner’s sexual behavior as barriers to practicing safe sex. Finally results also indicate that current HIV/AIDS prevention strategies in Puerto Rico are inadequate for these women. Discussion To address these issues the authors suggest cultural and social factors to be considered for the development of more effective HIV/AIDS prevention programs. PMID:18712603

Acute kidney injury is a common complication after cardiac surgery and is associated with increased morbidity and mortality and increased length of stay in the intensive care unit. Considering the high prevalence of acute kidney injury and its association with worsened prognosis, the development of strategies for renal protection in hospitals is essential to reduce the associated high morbidity and mortality, especially for patients at high risk of developing acute kidney injury, such as patients who undergo cardiac surgery. This integrative review sought to assess the evidence available in the literature regarding the most effective interventions for the prevention of acute kidney injury in patients undergoing cardiac surgery. To select the articles, we used the CINAHL and MedLine databases. The sample of this review consisted of 16 articles. After analyzing the articles included in the review, the results of the studies showed that only hydration with saline has noteworthy results in the prevention of acute kidney injury. The other strategies are controversial and require further research to prove their effectiveness.
A review about the effect of life style modification on diabetes and quality of life.
Shrestha, Prabha; Ghimire, Laxmi
2012-10-10
The aim of this review is to examine diabetes and quality of life improvements through modifying life style. The data was collected by reviewing published articles from PubMed, Medline, Web of Science, and Google open access publications. The review identified prevention strategies can reduce the risk and complications of diabetes. Life style modification in relation to obesity, eating habit, and physical exercise can play a major role in the prevention of diabetes. Nowadays, there has been progress in the development of behavioural strategies to modify these life style habits and it is not easy to accept for long term basis. If people maintain a balanced diet and physical exercise this can have real and potential benefits for their prevention and control of complications from chronic diseases particularly for cardiovascular risk and diabetes. Healthy life style may best be achieved through public private partnerships involving government, partners organizations, health services providers, community and people living with diabetes. Effective strategies to reduce the incidence of diabetes globally and assist in managing the disease are urgently required.

Through cost-benefit analysis (CBA), cost-effectiveness analysis (CEA) and quantitative optimization analysis to understand the economic benefit and outcomes of strategy regarding preventing mother-to-child transmission (PMTCT) on hepatitis B virus. Based on the principle of Hepatitis B immunization decision analytic-Markov model, strategies on PMTCT and universal vaccination were compared. Related parameters of Shenzhen were introduced to the model, a birth cohort was set up as the study population in 2013. The net present value (NPV), benefit-cost ratio (BCR), incremental cost-effectiveness ratio (ICER) were calculated and the differences between CBA and CEA were compared. A decision tree was built as the decision analysis model for hepatitis B immunization. Three kinds of Markov models were used to simulate the outcomes after the implementation of vaccination program. The PMTCT strategy of Shenzhen showed a net-gain as 38 097.51 Yuan/per person in 2013, with BCR as 14.37. The universal vaccination strategy showed a net-gain as 37 083.03 Yuan/per person, with BCR as 12.07. Data showed that the PMTCT strategy was better than the universal vaccination one and would end with gaining more economic benefit. When comparing with the universal vaccination program, the PMTCT strategy would save 85 100.00 Yuan more on QALY gains for every person. The PMTCT strategy seemed more cost-effective compared with the one under universal vaccination program. In the CBA and CEA hepatitis B immunization programs, the immunization coverage rate and costs of hepatitis B related diseases were the most important influencing factors. Outcomes of joint-changes of all the parameters in CEA showed that PMTCT strategy was a more cost-effective. The PMTCT strategy gained more economic benefit and effects on health. However, the cost of PMTCT strategy was more than the universal vaccination program, thus it is important to pay attention to the process of PMTCT strategy and the universal vaccination program. CBA seemed suitable for strategy optimization while CEA was better for strategy evaluation. Hopefully, programs as combination of the above said two methods would facilitate the process of economic evaluation.
Problem solving as a core strategy in the prevention of schizophrenia and other mental disorders.
Falloon, I R
2000-11-01
To outline the rationale for implementing training in structured problem solving as a primary prevention strategy for major mental disorders. The evidence that training people in a structured method of solving their personal problems is an effective strategy in the treatment of established cases of schizophrenic and major mood disorders, is selectively reviewed. Most of the relevant research focused on the prevention of major recurrent episodes of psychosis. There is some evidence to support the hypothesis that this strategy may assist many people to achieve a full and sustained recovery from the clinical and social impairments of these disorders, especially when patients are taught to use structured problem solving with members of their personal resource groups, and they continue to take optimal doses of psychoactive medication. There is support for the hypothesis that the key therapeutic factor associated with these benefits is the improved efficiency of the management of life stress. The simplicity of problem solving, the educational methods used, and the widespread application to a person's lifestyle would appear to make this a possible candidate for a primary prevention program for major mental disorders. Guidebooks and teaching aids have been developed and show excellent consumer acceptance.
A new paradigm for primary prevention strategy in people with elevated risk of stroke.
Feigin, Valery L; Norrving, Bo
2014-07-01
Existing methods of primary stroke prevention are not sufficiently effective. Based on the recently developed Stroke Riskometer app, a new 'mass-elevated risk stroke/cardiovascular disease prevention' approach as an addition to the currently adopted absolute risk stroke/cardiovascular disease prevention approach is being advocated. We believe this approach is far more appealing to the individuals concerned and could be as efficient as the conventional population-based approach because it allows identification and engagement in prevention of all individuals who are at an increased (even slightly increased) risk of stroke and cardiovascular disease. The key novelty of this approach is twofold. First, it utilizes modern far-reaching mobile technologies, allowing individuals to calculate their absolute risk of stroke within the next 5 to 10 years and to compare their risk with those of the same age and gender without risk factors. Second, it employs self-management strategies to engage the person concerned in stroke/cardiovascular disease prevention, which is tailored to the person's individual risk profile. Preventative strategies similar to the Stroke Riskometer could be developed for other non-communicable disorders for which reliable predictive models and preventative recommendations exist. This would help reduce the burden of non-communicable disorders worldwide. © 2014 The Authors.

To inform policy and decision makers, a cost-effectiveness model was developed to predict the cost-effectiveness of implementing two hypothetical management strategies separately and concurrently on the mitigation of deployment-associated travelers' diarrhea (TD) burden. The first management strategy aimed to increase the likelihood that a deployed service member with TD will seek medical care earlier in the disease course compared with current patterns; the second strategy aimed to optimize provider treatment practices through the implementation of a Department of Defense Clinical Practice Guideline. Outcome measures selected to compare management strategies were duty days lost averted (DDL-averted) and a cost effectiveness ratio (CER) of cost per DDL-averted (USD/DDL-averted). Increasing health care and by seeking it more often and earlier in the disease course as a stand-alone management strategy produced more DDL (worse) than the base case (up to 8,898 DDL-gained per year) at an increased cost to the Department of Defense (CER $193). Increasing provider use of an optimal evidence-based treatment algorithm through Clinical Practice Guidelines prevented 5,299 DDL per year with overall cost savings (CER -$74). A combination of both strategies produced the greatest gain in DDL-averted (6,887) with a modest cost increase (CER $118). The application of this model demonstrates that changes in TD management during deployment can be implemented to reduce DDL with likely favorable impacts on mission capability and individual health readiness. The hypothetical combination strategy evaluated prevents the most DDL compared with current practice and is associated with a modest cost increase.

Nearly 13 million new cancer cases and 7.6 million cancer deaths occur worldwide each year; 63% of cancer deaths occur in low- and middle-income countries. A substantial proportion of all cancers are attributable to carcinogenic exposures in the environment and the workplace. We aimed to develop an evidence-based global vision and strategy for the primary prevention of environmental and occupational cancer. We identified relevant studies through PubMed by using combinations of the search terms "environmental," "occupational," "exposure," "cancer," "primary prevention," and "interventions." To supplement the literature review, we convened an international conference titled "Environmental and Occupational Determinants of Cancer: Interventions for Primary Prevention" under the auspices of the World Health Organization, in Asturias, Spain, on 17-18 March 2011. Many cancers of environmental and occupational origin could be prevented. Prevention is most effectively achieved through primary prevention policies that reduce or eliminate involuntary exposures to proven and probable carcinogens. Such strategies can be implemented in a straightforward and cost-effective way based on current knowledge, and they have the added benefit of synergistically reducing risks for other noncommunicable diseases by reducing exposures to shared risk factors. Opportunities exist to revitalize comprehensive global cancer control policies by incorporating primary interventions against environmental and occupational carcinogens.

We determined the effectiveness of a community-based breast cancer education intervention among understudied populations in the New York State (NYS) Capital Region by assessing and comparing baseline and post-education breast cancer knowledge. Participants included 417 students recruited from five colleges/universities and 67 women from four community group organizations. Baseline and post-education knowledge was assessed via self-administered mostly multiple-choice questionnaires. An open-ended question soliciting opinions about public health prevention strategies against breast cancer was included on college/university students' questionnaires. Effectiveness of education intervention was estimated through a paired t test. Stratified analysis was done using demographic and descriptive variables. Answers to the open-ended questions were analyzed qualitatively. The mean percentage of correct answers increased from 39.9% at baseline to 80.8% post-education (P < 0.0001) among college/university students and from 43.5% to 77.8% (P < 0.0001) among community group members. Effectiveness remained statistically significant in all stratified analyses with similarly high percentage of correct answers achieved post-education irrespective of knowledge level at baseline. Stratified analysis also revealed similar patterns of improvement in overall knowledge and narrowing of the gap in post-education knowledge. Primary prevention emerged as the dominant theme post-education in students' responses to the open-ended question, signifying the effectiveness of our education in raising awareness about modifiable risk factors and inspiring proactive thinking about public health prevention strategies. This community-based education intervention was effective in increasing breast cancer knowledge among demographically diverse groups with low levels of baseline knowledge in the NYS Capital Region. Our findings provide leads for future public health prevention strategies.
Using Learning Strategies to Inhibit the Nocebo Effect.
Quinn, Veronica F; Colagiuri, Ben
2018-01-01
Learning is a key mechanism underpinning the development of the nocebo effect. The learning literature has cataloged and explored numerous ways in which the environment can be manipulated to prevent, reduce, or eradicate learning. Knowledge of these processes could be used to both inhibit the development of nocebo effects and reduce already established nocebo learning. This review describes the available evidence on how such learning strategies have, or could be, applied to reduce the nocebo effect in both healthy participants and patients to date. These learning strategies include overshadowing, latent inhibition, extinction, and contingency degradation. These strategies represent important new avenues for investigation and should be used by researchers to design and test interventions to reduce nocebo effects. © 2018 Elsevier Inc.

Environmental Strategies for Prevention of Drug Use and Risks in Clubs
Miller, Brenda A.; Holder, Harold D.; Voas, Robert B.
2009-01-01
Environmental prevention strategies in club settings where music and dance events are featured could provide an important new arena for the prevention of drug use and other risky behaviors (e.g., sexual risk taking, intoxication and drug use, aggression, and driving under the influence). Electronic music dance events (EMDEs) occur in clubs that attract young, emerging adults (18–25 years of age) and attract individuals who engage in various types of drug use. Borrowing from the environmental prevention studies that focus on reducing alcohol use and related problems, a model for drug prevention in the club setting is proposed. Initially, an overview of the relationships between EMDEs and drug use and other risky behaviors are presented. Next, rationales for environmental strategies are provided. Finally, an environmental approach to prevention of drug use and risky behaviors in clubs is described. This comprehensive set of environmental strategies, is designed to be mutually supportive and interactive. Environmental strategies are believed to provide potential for developing an efficacious prevention strategy. The environmental prevention approach presented here is composed of three intervention domains: (1) Mobilization, (2) Strategies for the Exterior Environment, and (3) Strategies for the Interior Environment.

Challenges and opportunities in suicide prevention in South-East Asia.
Vijayakumar, Lakshmi
2017-04-01
Suicide is a global public health problem, with over 800 000 people worldwide dying by suicide in 2012, according to the World Health Organization (WHO). The WHO South-East Asia Region is especially affected, with 39% of global suicides occurring in the 11 countries in this region. Women are a particularly vulnerable population, for a variety of social and cultural reasons. In India specifically, deaths by suicide for women peak in the age range 15-29 years. There is sufficient evidence to show that reduction of easy access to means of suicide is an effective prevention strategy. A common method of suicide in the region is by ingestion of pesticides. Strategies that have targeted limiting access to pesticides as a means of preventing suicide, such as the use of central storage and locked boxes, have shown promising results. Given the limited human and economic resources in these countries, it is essential to involve all stakeholders, including health services, voluntary and community organizations, teachers, social workers, traditional healers and other gatekeepers, in suicide prevention. A multisectoral approach, specifically targeting women and reducing easy access to pesticides, should be the way forward to reducing suicides in this region. In addition, more research is needed, to identify cost-effective and sustainable strategies.

2017-04-26
Colorectal cancer is a major healthcare concern worldwide. Many experimental and clinical studies have been conducted to date to discover agents that help in the prevention of this disease. Chronic inflammation in colonic mucosa and obesity, and its related metabolic abnormalities, are considered to increase the risk of colorectal cancer. Therefore, treatments targeting these factors might be a promising strategy to prevent the development of colorectal cancer. Among a number of functional foods, various phytochemicals, including tea catechins, which have anti-inflammatory and anti-obesity properties, and medicinal agents that ameliorate metabolic disorders, might also be beneficial in the prevention of colorectal cancer. In this review article, we summarize the strategies for preventing colorectal cancer by targeting obesity-related disorders and inflammation through nutraceutical and pharmaceutical approaches, and discuss the mechanisms of several phytochemicals and medicinal drugs used in basic and clinical research, especially focusing on the effects of green tea catechins.

Head and neck squamous cell carcinoma affects >45,000 Americans annually. Patients who are successfully treated for their primary tumor are at high risk of developing a second primary tumor, making effective preventive strategies highly desirable for this disease. Although a landmark study in 1990 suggested some benefit of high-dose retinoids in head and neck cancer prevention, subsequent trials using more tolerable doses have shown limited clinical success. Newer preventive strategies have included bioadjuvant therapy combining retinoids with interferon and {alpha}-tocopherol, combinations of molecularly targeted agents, and oncolytic viruses. Furthermore, considerable evidence has supported a cancer protective role for several nutrients,more » including green tea and curcumin analogs. Natural compounds such as these with favorable long-term safety profiles might be particularly suited to the cancer prevention setting, in which patients will usually tolerate only moderate risk and toxicity.« less
Child Sexual Abuse in Zimbabwe.
Mantula, Fennie; Saloojee, Haroon
2016-01-01
Although child sexual abuse is a significant public health problem globally, its incidence, prevention, and management is less well described in resource-poor settings. In poorer settings prevention initiatives assume even more importance since resources for managing abused children are severely limited. This article examines the current status of policy and practice related to the prevention of child sexual abuse in Zimbabwe. It identifies implementation challenges and highlights opportunities that could be embraced to reduce CSA in Zimbabwe, based on evidence synthesized from recent work. Although Zimbabwe has a well-established legal and regulatory framework to protect children from child sexual abuse, implementation of existing policies is weak. Financial, human, and material resource constraints are frequently cited to explain limited prevention activity. Effective strategies for the prevention of child sexual abuse should focus on implementing existing legislation, targeting schoolchildren, and getting community involvement. A dedicated budget would help entrench these strategies, but gains can be achieved even in the absence of this.

Prevention of early childhood caries: a public health perspective.
Weintraub, J A
1998-01-01
This paper proposes strategies for preventing early childhood caries (ECC), preferably for the greatest number of children at the lowest cost. Population-based, public health approaches are more likely to reach the target population groups at risk of developing ECC than individual, private practice-based approaches. Different prevention and early intervention strategies are discussed and the following recommendations are made: 1) Continue to promote community water fluoridation. 2) Evaluate the effectiveness of other public health oriented measures to prevent ECC. 3) Develop a national ECC and rampant caries registry. 4) Link oral health screening and easily implemented, low-cost interventions with immunization schedules and public health nursing activities. 5) Increase opportunities for community-based interventions conducted by dental hygienists. 6) Change insurance reimbursement schedules to provide incentives for dentists to prevent disease. 7) Include dentistry in new child health insurance legislation for children as well as parents of infants and preschool children.

Despite the widespread increase in online poker playing and the risk related to excessive poker playing, research on online poker websites is still lacking with regard to pathological gambling prevention strategies offered by the websites. The aim of the present study was to assess the pathological gambling-related prevention strategies of online poker websites. Two keywords ("poker" and "poker help") were entered into two popular World Wide Web search engines. The first 20 links related to French and English online poker websites were assessed. Seventy-four websites were assessed with a standardized tool designed to rate sites on the basis of accountability, interactivity, prevention strategies, marketing, and messages related to poker strategies. Prevention strategies appeared to be lacking. Whereas a substantial proportion of the websites offered incitation to gambling such as betting "tips," few sites offered strategies to prevent or address problem gambling. Furthermore, strategies related to poker, such as probability estimation, were mostly reported without acknowledging their limitations. Results of this study suggest that more adequate prevention strategies for risky gambling should be developed for online poker.

Background Younger adults are difficult to engage in preventive health, yet in Australia they are gaining more weight and increasing in waist circumference faster than middle-to-older adults. A further challenge to engaging 18- to 35-year-olds in interventions is the limited reporting of outcomes of recruitment strategies. Objective This paper describes the outcomes of strategies used to recruit young adults to a randomized controlled trial (RCT), healthy lifestyle mHealth program, TXT2BFiT, for prevention of weight gain. The progression from enquiry through eligibility check to randomization into the trial and the costs of recruitment strategies are reported. Factors associated with nonparticipation are explored. Methods Participants were recruited either via letters of invitation from general practitioners (GPs) or via electronic or print advertisements, including Facebook and Google—social media and advertising—university electronic newsletters, printed posters, mailbox drops, and newspapers. Participants recruited from GP invitation letters had an appointment booked with their GP for eligibility screening. Those recruited from other methods were sent an information pack to seek approval to participate from their own GP. The total number and source of enquiries were categorized according to eligibility and subsequent completion of steps to enrolment. Cost data and details of recruitment strategies were recorded. Results From 1181 enquiries in total from all strategies, 250 (21.17%) participants were randomized. A total of 5311 invitation letters were sent from 12 GP practices—16 participating GPs. A total of 131 patients enquired with 68 participants randomized (68/74 of those eligible, 92%). The other recruitment methods yielded the remaining 182 randomized participants. Enrolment from print media was 26% of enquiries, from electronic media was 20%, and from other methods was 3%. Across all strategies the average cost of recruitment was Australian Dollar (AUD) $139 per person. The least expensive modality was electronic (AUD $37), largely due to a free feature story on one university Web home page, despite Facebook advertising costing AUD $945 per enrolment. The most expensive was print media at AUD $213 and GP letters at AUD $145 per enrolment. Conclusions The research indicated that free electronic media was the most cost-effective strategy, with GP letters the least expensive of the paid strategies in comparison to the other strategies. This study is an important contribution for future research into efficacy, translation, and implementation of cost-effective programs for the prevention of weight gain in young adults. Procedural frameworks for recruitment protocols are required, along with systematic reporting of recruitment strategies to reduce unnecessary expenditure and allow for valuable public health prevention programs to go beyond the research setting.

Younger adults are difficult to engage in preventive health, yet in Australia they are gaining more weight and increasing in waist circumference faster than middle-to-older adults. A further challenge to engaging 18- to 35-year-olds in interventions is the limited reporting of outcomes of recruitment strategies. This paper describes the outcomes of strategies used to recruit young adults to a randomized controlled trial (RCT), healthy lifestyle mHealth program, TXT2BFiT, for prevention of weight gain. The progression from enquiry through eligibility check to randomization into the trial and the costs of recruitment strategies are reported. Factors associated with nonparticipation are explored. Participants were recruited either via letters of invitation from general practitioners (GPs) or via electronic or print advertisements, including Facebook and Google-social media and advertising-university electronic newsletters, printed posters, mailbox drops, and newspapers. Participants recruited from GP invitation letters had an appointment booked with their GP for eligibility screening. Those recruited from other methods were sent an information pack to seek approval to participate from their own GP. The total number and source of enquiries were categorized according to eligibility and subsequent completion of steps to enrolment. Cost data and details of recruitment strategies were recorded. From 1181 enquiries in total from all strategies, 250 (21.17%) participants were randomized. A total of 5311 invitation letters were sent from 12 GP practices-16 participating GPs. A total of 131 patients enquired with 68 participants randomized (68/74 of those eligible, 92%). The other recruitment methods yielded the remaining 182 randomized participants. Enrolment from print media was 26% of enquiries, from electronic media was 20%, and from other methods was 3%. Across all strategies the average cost of recruitment was Australian Dollar (AUD) $139 per person. The least expensive modality was electronic (AUD $37), largely due to a free feature story on one university Web home page, despite Facebook advertising costing AUD $945 per enrolment.

This study assessed the cost-effectiveness of a new, rapid human papillomavirus (HPV)-DNA screening test for cervical cancer prevention in the high-risk region of Shanxi, China. Using micro-costing methods, we estimated the resources needed to implement preventive strategies using cervical cytology or HPV-DNA testing, including the Hybrid Capture 2 (hc2) test (QIAGEN Corp., Gaithersburg, MD) and the rapid HPV-DNA careHPV test (QIAGEN). Data were used in a previously published model and empirically calibrated to country-specific epidemiological data. Strategies differed by initial test, targeted age, frequency of screening, number of clinic visits required (1, 2 or 3) and service delivery setting (national, county and township levels). Outcomes included lifetime risk of cancer, years of life saved (YLS), lifetime costs and incremental cost-effectiveness ratios (cost per YLS). For all screening frequencies, the most efficient strategy used 2-visit rapid HPV-DNA testing at the county level, including screening and diagnostics in the first visit, and treatment in the second visit. Screening at ages 35, 40 and 45 reduced cancer risk by 50% among women compliant with all 3 screening rounds, and was US$ 150 per YLS, compared with this same strategy applied twice per lifetime. This would be considered very cost-effective evaluated against China's per-capita gross domestic product (US$ 1,702). By enhancing the linkage between screening and treatment through a reduced number of visits, rapid HPV-DNA testing 3 times per lifetime is more effective than traditional cytology, and is likely to be cost-effective in high-risk regions of China.
The SOBANE strategy for the management of risk, as applied to whole-body or hand-arm vibration.
Malchaire, J; Piette, A
2006-06-01
The objective was to develop a coherent set of methods to be used effectively in industry to prevent and manage the risks associated with exposure to vibration, by coordinating the progressive intervention of the workers, their management, the occupational health and safety (OHS) professionals and the experts. The methods were developed separately for the exposure to whole-body and hand-arm vibration. The SOBANE strategy of risk prevention includes four levels of intervention: level 1, Screening; level 2, Observation; level 3, Analysis and; level 4, Expertise. The methods making it possible to apply this strategy were developed for 14 types of risk factors. The article presents the methods specific to the prevention of the risks associated with the exposure to vibration. The strategy is similar to those published for the risks associated with exposure to noise, heat and musculoskeletal disorders. It explicitly recognizes the qualifications of the workers and their management with regard to the work situation and shares the principle that measuring the exposure of the workers is not necessarily the first step in order to improve these situations. It attempts to optimize the recourse to the competences of the OHS professionals and the experts, in order to come more rapidly, effectively and economically to practical control measures.

The present study investigated the moderating effects of prevention-focus on the paths from the dimensions of insecure attachment (attachment avoidance and attachment anxiety) to depression. Two hundred twenty eight Korean college students completed the Experience in Close Relationship - Revised Scale; the Regulatory Focus Strategies Scale; and the Center for Epidemiologic Studies Depression Scale. Results revealed a significant moderating effect for prevention-focus on the path from attachment avoidance to depression, but not on the path from attachment anxiety to depression. They further suggest that different interventions are needed for different combinations of persons' insecure attachment dimensions and levels of prevention-focus. Counseling implications and suggestions for future research are discussed.

Colorectal cancer (CRC) is a leading cause of cancer-related mortality. CRC incidence and mortality can be reduced by several screening strategies, including colonoscopy, but randomized CRC prevention trials face significant obstacles such as the need for large study populations with long follow-up. Therefore, CRC screening strategies will likely be designed and optimized based on computer simulations. Several computational microsimulation tools have been reported for estimating efficiency and cost-effectiveness of CRC prevention. However, none of these tools is publicly available. There is a need for an open source framework to answer practical questions including testing of new screening interventions and adapting findings to local conditions. We developed and implemented a new microsimulation model, Colon Modeling Open Source Tool (CMOST), for modeling the natural history of CRC, simulating the effects of CRC screening interventions, and calculating the resulting costs. CMOST facilitates automated parameter calibration against epidemiological adenoma prevalence and CRC incidence data. Predictions of CMOST were highly similar compared to a large endoscopic CRC prevention study as well as predictions of existing microsimulation models. We applied CMOST to calculate the optimal timing of a screening colonoscopy. CRC incidence and mortality are reduced most efficiently by a colonoscopy between the ages of 56 and 59; while discounted life years gained (LYG) is maximal at 49-50 years. With a dwell time of 13 years, the most cost-effective screening is at 59 years, at $17,211 discounted USD per LYG. While cost-efficiency varied according to dwell time it did not influence the optimal time point of screening interventions within the tested range. Predictions of CMOST are highly similar compared to a randomized CRC prevention trial as well as those of other microsimulation tools. This open source tool will enable health-economics analyses in for various countries, health-care scenarios and CRC prevention strategies.

Background Given the increase in overweight and obesity prevalence in adolescents in the last decade, effective prevention strategies for these conditions in adolescents are urgently needed. The PRALIMAP (Promotion de l'ALImentation et de l'Activité Physique) trial aims to evaluate the effectiveness for these conditions of 3 health promotion strategies -- educational, screening and environmental -- applied singly or in combination in high schools over a 2-year intervention period. Methods PRALIMAP is a stratified 2 × 2 × 2 factorial cluster randomised controlled trial including 24 state high schools in Lorraine, northeastern France, in 2 waves: 8 schools in 2006 (wave 1) and 16 in 2007 (wave 2). Students entering the selected high schools in the 4 academic years from 2006 to 2009 are eligible for data collection. Interventional strategies are organized over 2 academic years. The follow-up consists of 3 visits: at the entry of grade 10 (T0), grade 11 (T1) and grade 12 (T2). At T0, 5,458 (85.7%) adolescents participated. The educational strategy consists of nutritional lessons, working groups and a final party. The screening strategy consists in detecting overweight/obesity and eating disorders in adolescents and proposing, if necessary, an adapted care management program of 7 group educational sessions. The environmental strategy consists in improving dietary and physical activity offerings in high schools and facilities, especially catering. The main outcomes are body size evolution over time, nutritional behaviour and knowledge, health and quality of life. An evaluation process documents how each intervention strategy is implemented in the schools and estimates the dose of the intervention, allowing for a per protocol analysis after the main intention-to-treat analysis. Discussion PRALIMAP aims at improving the prevention and management of overweight and obesity in adolescents by translating current evidence into public health practice. Particular attention is paid to clustering, multiple factorials and long-term duration to address common pitfalls in health promotion trials. The results should inform how best to implement, in a school environment, effective nutrition prevention programs targeting adolescents who are at a point their lives when they develop responsibilities and empowerment for health attitude behaviours.

The purpose of this study was to establish landslide risk analysis procedures that can be used to analyze landslide risk in a watershed scale and to assess the effectiveness of risk mitigation strategies. Landslide risk analysis encompassed the landslide hazard, the vulnerability of elements at risk, and community resilience capacity. First, landslide spatial probability, landslide temporal probability, and landslide area probability were joined to estimate the probability of landslides with an area exceeding a certain threshold in each slope unit. Second, the expected property and life losses were both analyzed in vulnerability analysis. Different elements at risk were assigned corresponding values, and then used in conjunction with the vulnerabilities to carry out quantitative analysis. Third, the resilience capacity of different communities was calculated based on the scores obtained through community checklists and the weights of individual items, including "the participation experience of disaster prevention drill," "real-time monitoring mechanism of community," "autonomous monitoring of residents," and "disaster prevention volunteer." Finally, the landslide probabilities, vulnerability analysis results, and resilience capacities were combined to assess landslide risk in Shihmen Watershed. In addition, the risks before and after the implementation of non-structural disaster prevention strategies were compared to determine the benefits of various strategies, and subsequently benefit-cost analysis was performed. Communities with high benefit-cost ratios included Hualing, Yisheng, Siouluan, and Gaoyi. The watershed as a whole had a benefit-cost ratio far greater than 1, indicating that the effectiveness of strategies was greater than the investment cost, and these measures were thus cost-effective. The results of factor sensitivity analysis revealed that changes in vulnerability and mortality rates would increase the uncertainty of risk, and that raise in annual interest rates or reduction in life cycle of measures would decrease the benefit-cost ratio. However, with regard to effectiveness analysis, these changes did not reverse the cost-effective inference.

BACKGROUND Metachronous Colorectal Cancer (MCRC) incidence amongst colorectal cancer (CRC) survivors varies significantly and the optimal colonoscopy surveillance practice to mitigate MCRC incidence is unknown. METHODS We conducted a cost-effectiveness analysis by comparing performances of the US Multi-Society Task Force guideline and all clinically-reasonable colonoscopy surveillance strategies among 50–79-year-old post-treatment CRC patients using a computer-simulation model. RESULTS The US guideline [(1,3,5)] recommends the first colonoscopy 1-year after treatment while the second and third colonoscopies are repeated with 3- and 5-year intervals. We identified some promising alternative cost-effective strategies. Compared to the US guideline under various scenarios for 20-year period, 1) reducing the surveillance interval of the guideline after the first colonoscopy by 1-year [(1,2,5)] saves/prevents up to 78 discounted-life-years and 23 MCRCs per 1000-patients (incremental cost-effectiveness ratio (ICER)≤$23,270/life-year); 2) reducing the intervals after the first and second negative colonoscopy by 1-year [(1,2,4)] saves/prevents up to 109 discounted-life-years and 36 MCRCs (ICER≤$52,155/life-year); 3) (1,2,3) saves/prevents up to 141 discounted-life-years and 50 MCRCs (ICER≤$68,822/life-year). These strategies require up to 1100 additional colonoscopies per 1000-patients. Although, the US guideline may not be cost-effective compared to less-intensive oncology guideline (3,3,5) (ICER can be as high as $140,000/LY), the promising strategies are cost-effective compared to such less-intensive guidelines unless cumulative MCRC incidence is very low. CONCLUSIONS The US guideline might be improved by slightly increasing the surveillance intensity at the expense of moderately increased cost. More research is warranted to explore the benefits/harms of such practices. PMID:27248907
The economics of pit and fissure sealants in preventive dentistry: a review.
Kitchens, Dinah H
2005-08-15
Oral diseases are progressive, cumulative, and become more intricate to treat with advancement. While dental caries is an infectious transmissible disease with children being at the highest risk, primary prevention can reduce this risk. Primary prevention in dentistry is usually considered to be community fluoridated water supplies, professional fluoride treatments, and pit and fissure sealants. While community fluoridated water supplies have been proven to be cost-effective, the cost-effectiveness of pit and fissure sealants has primarily been studied in school-based programs of children from low socio-economic backgrounds. Dental sealant programs are just one way to help increase primary prevention in the oral health disparities of children. The purpose of this paper is to review the literature regarding the cost-effectiveness of pit and fissure sealants as a preventive strategy in preventive dentistry.

In the Americas, mean energy intake from added sugar exceeds recent World Health Organization recommendations for free sugars in the diet. As a leading contributor to this excess, sugar-sweetened beverage (SSB) overconsumption represents a risk for the population's health. This article provides an overview of clinical and epidemiological evidence, marketing practices, corporate influence and prevention strategies related to added sugar and SSB. For each aspect of this multidimensional profile, we briefly compare SSB to the case of tobacco pointing to similarities but also major differences. Tobacco control has demonstrated the effectiveness of long term multifaceted prevention strategies in multiple settings supported by strong public policies which may be applied to the consumption of SSB. However, translating these policies to the specific case of SSB is urgently needed, to inform preventive actions, decide which intervention mix will be used, and evaluate the process and impact of the chosen strategy.

Disease simulation models of the health and economic consequences of different prevention and treatment strategies can guide policy decisions about cancer control. However, models that also consider health disparities can identify strategies that improve both population health and its equitable distribution. We devised a typology of cancer disparities that considers types of inequalities among black, white, and Hispanic populations across different cancers and characteristics important for near-term policy discussions. We illustrated the typology in the specific example of cervical cancer using an existing disease simulation model calibrated to clinical, epidemiological, and cost data for the United States. We calculated average reduction in cancer incidence overall and for black, white, and Hispanic women under five different prevention strategies (Strategies A1, A2, A3, B, and C) and estimated average costs and life expectancy per woman, and the cost-effectiveness ratio for each strategy. Strategies that may provide greater aggregate health benefit than existing options may also exacerbate disparities. Combining human papillomavirus vaccination (Strategy A2) with current cervical cancer screening patterns (Strategy A1) resulted in an average reduction of 69% in cancer incidence overall but a 71.6% reduction for white women, 68.3% for black women, and 63.9% for Hispanic women. Other strategies targeting risk-based screening to racial and ethnic minorities reduced disparities among racial subgroups and resulted in more equitable distribution of benefits among subgroups (reduction in cervical cancer incidence, white vs. Hispanic women, 69.7% vs. 70.1%). Strategies that employ targeted risk-based screening and new screening algorithms, with or without vaccination (Strategies B and C), provide excellent value. The most effective strategy (Strategy C) had a cost-effectiveness ratio of $28,200 per year of life saved when compared with the same strategy without vaccination. We identify screening strategies for cervical cancer that provide greater aggregate health benefit than existing options, offer excellent cost-effectiveness, and have the biggest positive impact in worst-off groups. The typology proposed here may also be useful in research and policy decisions when trade-offs between fairness and cost-effectiveness are unavoidable.

Abstract Expanding essential health services through non‐government organisations (NGOs) is a central strategy for achieving universal health coverage in many low‐income and middle‐income countries. Human immunodeficiency virus (HIV) prevention services for key populations are commonly delivered through NGOs and have been demonstrated to be cost‐effective and of substantial global public health importance. However, funding for HIV prevention remains scarce, and there are growing calls internationally to improve the efficiency of HIV prevention programmes as a key strategy to reach global HIV targets. To date, there is limited evidence on the determinants of costs of HIV prevention delivered through NGOs; and thus, policymakers have little guidance in how best to design programmes that are both effective and efficient. We collected economic costs from the Indian Avahan initiative, the largest HIV prevention project conducted globally, during the first 4 years of its implementation. We use a fixed‐effect panel estimator and a random‐intercept model to investigate the determinants of average cost. We find that programme design choices such as NGO scale, the extent of community involvement, the way in which support is offered to NGOs and how clinical services are organised substantially impact average cost in a grant‐based payment setting. © 2016 The Authors.

Chronic diseases are a serious and urgent problem, requiring at-scale, multi-component, multi-stakeholder action and cooperation. Despite numerous national frameworks and agenda-setting documents to coordinate prevention efforts, Australia, like many countries internationally, is yet to substantively impact the burden from chronic disease. Improved evidence on effective strategies for the prevention of chronic disease is required. This research sought to articulate a priority set of important and feasible action domains to inform future discussion and debate regarding priority areas for chronic disease prevention policy and strategy. Using concept mapping, a mixed-methods approach to making use of the best available tacit knowledge of recognised, diverse and well-experienced actors, and national actions to improve the prevention of chronic disease in Australia were identified and then mapped. Participants (ranging from 58 to 78 in the various stages of the research) included a national sample of academics, policymakers and practitioners. Data collection involved the generation and sorting of statements by participants. A series of visual representations of the data were then developed. A total of 95 statements were distilled into 12 clusters for action, namely Inter-Sectoral Partnerships; Systems Perspective/Action; Governance; Roles and Responsibilities; Evidence, Feedback and Learning; Funding and Incentive; Creating Demand; Primary Prevention; Social Determinants and Equity; Healthy Environments; Food and Nutrition; and Regulation and Policy. Specific areas for more immediate national action included refocusing the health system to prevention over cure, raising the profile of public health with health decision-makers, funding policy- and practice-relevant research, improving communication about prevention, learning from both global best-practice and domestic successes and failures, increasing the focus on primary prevention, and developing a long-term prevention strategy with an explicit funding commitment. Preventing chronic diseases and their risk factors will require at-scale, multi-component, multi-stakeholder action and cooperation. The concept mapping procedures used in this research have enabled the synthesis of views across different stakeholders, bringing both divergent and convergent perspectives to light, and collectively creating signals for where to prioritise national action. Previous national strategies for chronic disease prevention have not collated the tacit knowledge of diverse actors in the prevention of chronic disease in this structured way.

Chronicles in Drug Discovery features special interest reports on advances in drug discovery. This month we highlight new options to prevent oral mucositis, a treatment-limiting adverse effect of chemotherapy. Studies are currently focusing on mechanism-based therapies to prevent or repair DNA damage to epithelial and submucosal cells and the cascade or events that follow to cause tissue damage or analgesics to ease the associated oral cavity pain. Therapeutic limitations also exist for the use of the highly effective antibiotic gentamicin, as it evokes acute renal failure. Mechanistic investigations have shed some light on potential targets: the kallikreins, peroxynitrite-related pathways, superoxide production and the accumulation of aminoglycosides. New antibiotic strategies for trachoma, the leading cause of preventable blindness, are also explored along with studies to aid the development of vaccine candidates. Finally, we discuss the utility of allosteric-potentiating ligands to modulate nicotinic acetylcholine receptors, mimicking the reward/addictive effects of nicotine, as potential strategies for smoking cessation.

The development of anemia after birth in very premature, critically ill newborn infants is a universal well-described phenomenon. Although preventing anemia in this population, along with efforts to establish optimal red blood cell (RBC) transfusion and pharmacologic therapy continue to be actively investigated, the present review focuses exclusively on nonpharmacological approaches to the prevention and treatment of neonatal anemia. We begin with an overview of topics relevant to nonpharmacological techniques. These topics include neonatal and fetoplacental hemoglobin levels and blood volumes, clinical and laboratory practices applied in critically ill neonates, and current RBC transfusion practice guidelines. This is followed by a discussion of the most effective and promising nonpharmacological blood conservation strategies and techniques. Fortunately, many of these techniques are feasible in most neonatal intensive care units. When applied together, these techniques are more effective than existing pharmacotherapies in significantly decreasing neonatal RBC transfusions. They include increasing hemoglobin endowment and circulating blood volume at birth; removing less blood for laboratory testing; and optimizing nutrition. PMID:22818543
Implementing a pressure ulcer prevention bundle in an adult intensive care.
Tayyib, Nahla; Coyer, Fiona; Lewis, Peter A
2016-12-01
The incidence of pressure ulcers (PUs) in intensive care units (ICUs) is high and numerous strategies have been implemented to address this issue. One approach is the use of a PU prevention bundle. However, to ensure success care bundle implementation requires monitoring to evaluate the care bundle compliance rate, and to evaluate the effectiveness of implementation strategies in facilitating practice change. The aims of this study were to appraise the implementation of a series of high impact intervention care bundle components directed at preventing the development of PUs, within ICU, and to evaluate the effectiveness of strategies used to enhance the implementation compliance. An observational prospective study design was used. Implementation strategies included regular education, training, audit and feed-back and the presence of a champion in the ICU. Implementation compliance was measured along four time points using a compliance checklist. Of the 60 registered nurses (RNs) working in the critical care setting, 11 participated in this study. Study participants demonstrated a high level of compliance towards the PU prevention bundle implementation (78.1%), with 100% participant acceptance. No significant differences were found between participants' demographic characteristics and the compliance score. There was a significant effect for time in the implementation compliance (Wilks Lambda=0.29, F (3, 8)=6.35, p<0.016), indicating that RNs needed time to become familiar with the bundle and routinely implement it into their practice. PU incidence was not influenced by the compliance level of participants. The implementation strategies used showed a positive impact on compliance. Assessing and evaluating implementation compliance is critical to achieve a desired outcome (reduction in PU incidence). This study's findings also highlighted that while RNs needed time to familiarise themselves with the care bundle elements, their clinical practice was congruent with the bundle elements.

If Suicide Is a Public Health Problem, What Are We Doing to Prevent It?
Knox, Kerry L.; Conwell, Yeates; Caine, Eric D.
2004-01-01
Although not a disease, suicide is a tragic endpoint of complex etiology and a leading cause of death worldwide. Just as preventing heart disease once meant that specialists treated myocardial infarctions in emergency care settings, in the past decade, suicide prevention has been viewed as the responsibility of mental health professionals within clinical settings. By contrast, over the past 50 years, population-based risk reduction approaches have been used with varying levels of effectiveness to prevent morbidity and mortality associated with heart disease. We examined whether the current urgency to develop effective interventions for suicide prevention can benefit from an understanding of the evolution of population-based strategies to prevent heart disease.

Despite the potential to reach at-risk children in childcare, there is a significant gap between current practices and evidence-based obesity prevention in this setting. There are few investigations of the impact of implementation strategies on the uptake of evidence-based practices (EBPs) for obesity prevention and nutrition promotion. This study protocol describes a three-phase approach to developing and testing implementation strategies to support uptake of EBPs for obesity prevention practices in childcare (i.e., key components of the WISE intervention). Informed by the i-PARIHS framework, we will use a stakeholder-driven evidence-based quality improvement (EBQI) process to apply information gathered in qualitative interviews on barriers and facilitators to practice to inform the design of implementation strategies. Then, a Hybrid Type III cluster randomized trial will compare a basic implementation strategy (i.e., intervention as usual) with an enhanced implementation strategy informed by stakeholders. All Head Start centers (N = 12) within one agency in an urban area in a southern state in the USA will be randomized to receive the basic or enhanced implementation with approximately 20 classrooms per group (40 educators, 400 children per group). The educators involved in the study, the data collectors, and the biostastician will be blinded to the study condition. The basic and enhanced implementation strategies will be compared on outcomes specified by the RE-AIM model (e.g., Reach to families, Effectiveness of impact on child diet and health indicators, Adoption commitment of agency, Implementation fidelity and acceptability, and Maintenance after 6 months). Principles of formative evaluation will be used throughout the hybrid trial. This study will test a stakeholder-driven approach to improve implementation, fidelity, and maintenance of EBPs for obesity prevention in childcare. Further, this study provides an example of a systematic process to develop and test a tailored, enhanced implementation strategy. ClinicalTrials.gov, NCT03075085.

An estimated 1 in 150 infants is born each year with congenital cytomegalovirus (CMV); nearly 1 in 750 suffers permanent disabilities. Congenital CMV is the result of a pregnant woman becoming infected with CMV. Educating pregnant women about CMV is currently the best approach to prevention. Limited research is available on how to effectively communicate with women about CMV. We conducted formative research on fear appeals theory-based messages about CMV and prevention with U.S. women. Fear appeal theories suggest that message recipients will take action if they feel fear. First, we conducted in-depth interviews (N = 32) with women who had young children who tested positive for CMV. Second, we conducted eight focus groups (N = 70) in two phases and two cities (Phase 2: Atlanta, GA; Phase 3: San Diego, CA) with pregnant women and non-pregnant women who had young children. Few participants knew about CMV before the focus groups. Participants reviewed and gave feedback on messages created around fear appeals theory-based communication concepts. The following concepts were tested in one or more of the three phases of research: CMV is severe, CMV is common, CMV is preventable, CMV preventive strategies are similar to other behavior changes women make during pregnancy, CMV preventive strategies can be incorporated in moderation to reduce exposure, and CMV is severe but preventable. Participants recommended communicating that CMV is common by using prevalence ratios (e.g., 1 in 150) or comparing CMV to other well-known disabilities. To convey the severity of CMV, participants preferred stories about CMV along with prevention strategies. Participants also welcomed prevention strategies when it included a message about risk reduction. In general, participants said messages were motivating, even if they felt that it could be difficult to make certain behavior changes. Findings from this research can contribute to future efforts to educate pregnant women about CMV, especially regarding use of fear appeals-based messages. Pregnant women may face certain challenges to practicing prevention strategies but, overall, are motivated make changes to increase their chances of having a healthy baby.

Summary Background Cardiovascular disease is the leading cause of death, with 80% of cases occurring in developing countries. We therefore aimed to establish whether use of evidence-based multidrug regimens for patients at high risk for cardiovascular disease would be cost-effective in low-income and middle-income countries. Methods We used a Markov model to do a cost-effectiveness analysis with two combination regimens. For primary prevention, we used aspirin, a calcium-channel blocker, an angiotensin-converting-enzyme inhibitor, and a statin, and assessed them in four groups with different thresholds of absolute risks for cardiovascular disease. For secondary prevention, we assessed the same combination of drugs in one group, but substituted a β blocker for the calcium-channel blocker. To compare strategies, we report incremental cost-effectiveness ratios (ICER), in US$ per quality-adjusted life-year (QALY). Findings We recorded that preventive strategies could result in a 2-year gain in life expectancy. Across six developing World Bank regions, primary prevention yielded ICERs of US$746–890/QALY gained for patients with a 10-year absolute risk of cardiovascular disease greater than 25%, and $1039–1221/QALY gained for those with an absolute risk greater than 5%. ICERs for secondary prevention ranged from $306/QALY to $388/QALY gained. Interpretation Regimens of aspirin, two blood-pressure drugs, and a statin could halve the risk of death from cardiovascular disease in high-risk patients. This approach is cost-effective according to WHO recommendations, and is robust across several estimates of drug efficacy and of treatment cost. Developing countries should encourage the use of these inexpensive drugs that are currently available for both primary and secondary prevention. PMID:16920473
From modeling to morals: imagining the future of HIV PREP in Lesotho.
Kenworthy, Nora J; Bulled, Nicola
2013-08-01
Amidst growing global endorsements of new biomedical HIV prevention strategies, ARV-based pre-exposure prophylaxis (ARV PrEP) has garnered considerable attention as a potentially promising prevention strategy. Though it may offer more effective protection for certain at-risk groups than conventional prevention strategies (such as sexual partner reduction, condom use, and prevention of mother-to-child transmission), PrEP is more costly. PrEP requires more ongoing contact between individuals and providers, and a level of surveillance from the health system that is not necessary with other preventive measures. In this sense, it represents a new bio-technology for HIV prevention that poses particular challenges for worldwide implementation, given developing countries' struggling health systems and incomplete HIV treatment programs. Since the emergence of PrEP has stimulated ethical discussions premised on incomplete knowledge of efficacy and implementation, this paper explores the ethical parameters of a likely scenario for PrEP usage in a single, resource-poor country. We first develop a plausible model for PrEP deployment and utilization based on current PrEP research, while carefully considering the reigning institutional values of feasibility and effectiveness in global health approaches. Drawing on ethnographic research of HIV treatment and prevention approaches in Lesotho, we address ethical questions arising from this scenario of PrEP delivery. Lesotho presents a compelling and emblematic case study of PrEP's potential successes and pitfalls in a developing country, given the country's high HIV prevalence, struggles to achieve universal access to HIV treatment regimes, continued existence of stigma around the epidemic, and difficulties in addressing persistent social inequalities that fuel infections. © 2013 John Wiley & Sons Ltd.

Between 2006 and 2009 the largest human Q fever epidemic ever described occurred in the Netherlands. The source of infection was traced back to dairy goat herds with abortion problems due to Q fever. The first aim of control measures taken in these herds was the reduction of human exposure. To analyze Q fever dynamics in goat herds and to study the effect of control measures, a within-herd model of Coxiella burnetii transmission in dairy goat herds was developed. With this individual-based stochastic model we evaluated six control strategies and three herd management styles and studied which strategy leads to a lower Q fever prevalence and/or to disease extinction in a goat herd. Parameter values were based on literature and on experimental work. The model could not be validated with independent data. The results of the epidemiological model were: (1) Vaccination is effective in quickly reducing the prevalence in a dairy goat herd. (2) When taking into account the average time to extinction of the infection and the infection pressure in a goat herd, the most effective control strategy is preventive yearly vaccination, followed by the reactive strategies to vaccinate after an abortion storm or after testing BTM (bulk tank milk) positive. (3) As C. burnetii in dried dust may affect public health, an alternative ranking method is based on the cumulative amount of C. burnetii emitted into the environment (from disease introduction until extinction). Using this criterion, the same control strategies are effective as when based on time to extinction and infection pressure (see 2). (4) As the bulk of pathogen excretion occurs during partus and abortion, culling of pregnant animals during an abortion storm leads to a fast reduction of the amount of C. burnetii emitted into the environment. However, emission is not entirely prevented and Q fever will not be eradicated in the herd by this measure. (5) A search & destroy (i.e. test and cull) method by PCR of individual milk samples with a detection probability of 50% of detecting and culling infected goats - that excrete C. burnetii intermittently - will not result in eradication of Q fever in the herd. This control strategy was the least effective of the six evaluated strategies. Subject to model limitations, our results indicate that only vaccination is capable of preventing and controlling Q fever outbreaks in dairy goat farms. Thus, preventive vaccination should be considered as an ongoing control measure. Copyright © 2015 Elsevier B.V. All rights reserved.

To compare the effectiveness of a digital video disc (DVD) with that of a written workbook delivering falls prevention education to older hospital patients on self-perceived risk of falls, perception of falls epidemiology, knowledge of prevention strategies, and motivation and confidence to engage in self-protective strategies. To compare the effect of receiving either education approach versus no education on patients' perception of falls epidemiology. Randomized trial (DVD vs workbook) with additional quasi-experimental control group. Geriatric, medical, and orthopedic wards in Perth and Brisbane, Australia. One hundred (n=51 DVD, n=49 workbook) hospital inpatients aged 60 and older receiving an intervention (mean age 75.3+/-10.1) and 122 in the control group (mean age 79.3+/-8.3). Participants randomly assigned to receive identical educational material on falls prevention delivered on a DVD or in a workbook. Control group received usual care. Custom-designed survey addressing elements of the Health Belief Model of health behavior change. Participants randomized to DVD delivery had a higher self-perceived risk of falling (P=.04) and higher levels of confidence (P=.03) and motivation (P=.04) to engage in self-protective strategies than participants who received the workbook. A higher proportion of participants who received either form of the education provided "desired" responses than of control group participants across all knowledge items (P<.001). Delivery of falls prevention education on a DVD compared to a written workbook is more likely to achieve important changes in parameters likely to affect successful uptake of falls prevention messages in the hospital setting.

While the reduction in fall rates has not kept pace with the reduction of other hospital-acquired conditions, patient safety research and quality improvement (QI) initiatives at the system and hospital levels have achieved positive results and provide insights into potentially effective risk reduction strategies. An academic medical center developed a QI-based multicomponent strategy for fall prevention and pilot tested it for six months in three high-risk units-the Neuroscience Acute Care Unit, the Myelosuppression/Stem Cell Transplant Unit, and the Acute Care for the Elderly Unit-before implementing and evaluating the strategy hospitalwide. The multicomponent fall strategy was evaluated using a pre-post study design. The main outcome measures were falls and falls with harm measured in events per 1,000 patient-days. Fall rates were monitored and compared for three classes of falls: (1) accidental, (2) anticipated physiologic, and (3) unanticipated physiologic. Statistical process control charts showed that the pilot units had achieved significant reductions in falls with harm during the last five months of data collection. Wald test and segmented regression analyses revealed significant improvements in pooled postintervention fall rates, stratified by fall type. The hospitalwide implementation of the program resulted in a 47% overall reduction in falls in the postintervention period. A fall prevention strategy that targeted the spectrum of risk factors produced measurable improvement in fall rates and rates of patient harm. Hospitals must continue developing, rigorously testing, and sharing their results and experiences in implementing and sustaining multicomponent fall prevention strategies.

Pressure ulcer prevention and management strategies in Turkey.
Acaroglu, Rengin; Sendir, Merdiye
2005-01-01
Pressure ulcers are a serious problem that can lead to pain and delayed recovery. In Turkey, the selection of dressing products is usually left to the nurse managing the patient and depends on several factors, including the condition of the wound, the nurse's knowledge, and the nurse's experience. The aim of this study was to determine prevention and management strategies for pressure ulcer care in hospitalized patients in Turkey and to identify the factors that influence the selection of products by nurses. The descriptive study was carried out in various departments (orthopedic, neurological, oncology, and intensive care) where bedridden patients were found. A total of 110 nurses volunteered to participate. Data were collected by means of a questionnaire developed after a review of the literature. Only 32% of the nurses made use of a pressure ulcer care risk evaluation scale (Norton scale), and air mattresses were used by 89% as a preventive measure with patients who were at risk. When pressure ulcers occurred, advanced wound care products were preferred by most of the nurses. Seventy four percent of nurses considered the condition of wound for selection of products. Despite correctly noting several strategies for prevention of pressure ulcers, 9% of nurses also described massage around boney prominence and the use of inflatable rings as effective preventive strategies. This descriptive study shows that nurses in Turkey are primarily responsible for prevention and management of pressure ulcer care and that both traditional dressing products and advanced wound care products are used in the care of all stages of pressure ulcers in Turkey. It also illustrates the need for ongoing pressure ulcer education to promote evidence-based practice and reduce the use of ineffective (or harmful) strategies.

More than 1 billion children - half the children in the world - are victims of violence every year. As part of the Post-2015 sustainable development agenda, the UN has issued a global call-to-action: to eliminate violence against children. Essential to preventing violence against children is guidance to countries on using the best available evidence to address this problem. THRIVES provides this evidence. It represents a framework of complementary strategies that, taken together, have potential to achieve and sustain efforts to prevent violence against children. These strategies, which span health, social services, education, and justice sectors, include Training in parenting, Household economic strengthening, Reduced violence through legislative protection, Improved services, Values and norms that protect children, Education and life skills, and Surveillance and evaluation. For each THRIVES area, we review evidence for effectiveness and identify programmatic or policy examples. This framework will facilitate commitments to effective, sustainable, and scalable action.
Adolescents' perceptions of substance abuse prevention strategies.
Lisnov, L; Harding, C G; Safer, L A; Kavanagh, J
1998-01-01
As part of a 3-year evaluation of substance abuse prevention strategies (Harding, Safer, Kavanagh, Bania, Carty, Lisnov, & Wysockey, 1996), this study examined the perceptions of 719 sixth- through ninth-grade Chicago public school students. School-based programs were rated as significantly more effective on six prevention objectives than were television ads, testimonials by famous people, billboards, and print ads displayed on public transportation. Students perceived the two school-based programs, Project DARE (a national program conducted through local police departments) and Captain Clean (an intense live theater program coordinated with student participation), as being equally effective overall, although the interactive theater program was rated as significantly better at encouraging students to talk about their feelings concerning substance abuse issues and at relating to the students' ethnic/racial backgrounds. When students were categorized according to frequency of alcohol use, nonusers, infrequent users, and frequent users differed significantly in their ratings of the school-based programs.
[Evidence-based prevention: a new model for public health].
Vitale, Francesco; Cusimano, Rosanna; Bruno, Giuseppe; Firenze, Alberto; De Crescenzo, Loredana; Romano, Nino
2005-01-01
The concept of evidence-based prevention (EBP), was developed during the last decade as the counterpart, in Public Health, of Evidence-Based Medicine (EBM) in Clinical Medicine. The growing debate on EBP reflects the increasing recognition that successful evaluation of public health interventions will necessarily entail the use of research designs other than controlled trials as well as the use of various other types of evidence, often in combination. Evidence-based prevention, therefore, aims to implement those prevention strategies that have been found to be useful and effective through a formal evaluation based on scientific methodology. A the same it aims to progressively discard all preventive practices for which usefulness and effectiveness have not been proved.

Compliant flooring, broadly defined as flooring systems or floor coverings with some level of shock absorbency, may reduce the incidence and severity of fall-related injuries in older adults; however, a lack of synthesized evidence may be limiting widespread uptake. Informed by the Arksey and O'Malley framework and guided by a Research Advisory Panel of knowledge users, we conducted a scoping review to answer: what is presented about the biomechanical efficacy, clinical effectiveness, cost-effectiveness, and workplace safety associated with compliant flooring systems that aim to prevent fall-related injuries in healthcare settings? We searched academic and grey literature databases. Any record that discussed a compliant flooring system and at least one of biomechanical efficacy, clinical effectiveness, cost-effectiveness, or workplace safety was eligible for inclusion. Two independent reviewers screened and abstracted records, charted data, and summarized results. After screening 3611 titles and abstracts and 166 full-text articles, we included 84 records plus 56 companion (supplementary) reports. Biomechanical efficacy records (n = 50) demonstrate compliant flooring can reduce fall-related impact forces with minimal effects on standing and walking balance. Clinical effectiveness records (n = 20) suggest that compliant flooring may reduce injuries, but may increase risk for falls. Preliminary evidence suggests that compliant flooring may be a cost-effective strategy (n = 12), but may also result in increased physical demands for healthcare workers (n = 17). In summary, compliant flooring is a promising strategy for preventing fall-related injuries from a biomechanical perspective. Additional research is warranted to confirm whether compliant flooring (i) prevents fall-related injuries in real-world settings, (ii) is a cost-effective intervention strategy, and (iii) can be installed without negatively impacting workplace safety. Avenues for future research are provided, which will help to determine whether compliant flooring is recommended in healthcare environments.

PPACA epitomizes comprehensive health care reform legislation. Public health, disease prevention, and wellness were integral considerations in its development. This article reveals the author's personal experiences while working on the framework for health care reform in the United States Senate and reviews activity in the United States House of Representatives. This insider's perspective delineates PPACA's positive effect on public health by examining the infrastructure Congress designed to focus on prevention, wellness, and public health, with a particular focus on the National Prevention, Health Promotion and Public Health Council; the National Prevention, Health Promotion, Public Health, and Integrative Health Care Strategy; and the Prevention and Public Health Fund. The Council, strategy, and fund are especially important because they reflect compliance with some of the Institute of Medicine's recommendations to improve public health in the United States, as well as international health and human rights norms that protect the right to health. © 2011 American Society of Law, Medicine & Ethics, Inc.
RANKL/RANK: from bone loss to the prevention of breast cancer.
Sigl, Verena; Jones, Laundette P; Penninger, Josef M
2016-11-01
RANK and RANKL, a receptor ligand pair belonging to the tumour necrosis factor family, are the critical regulators of osteoclast development and bone metabolism. Besides their essential function in bone, RANK and RANKL have also been identified as the key factors for the formation of a lactating mammary gland in pregnancy. Mechanistically, RANK and RANKL link the sex hormone progesterone with stem cell expansion and proliferation of mammary epithelial cells. Based on their normal physiology, RANKL/RANK control the onset of hormone-induced breast cancer through the expansion of mammary progenitor cells. Recently, we and others were able to show that RANK and RANKL are also critical regulators of BRCA1-mutation-driven breast cancer. Currently, the preventive strategy for BRCA1-mutation carriers includes preventive mastectomy, associated with wide-ranging risks and psychosocial effects. The search for an alternative non-invasive prevention strategy is therefore of paramount importance. As our work strongly implicates RANK and RANKL as key molecules involved in the initiation of BRCA1-associated breast cancer, we propose that anti-RANKL therapy could be a feasible preventive strategy for women carrying BRCA1 mutations, and by extension to other women with high risk of breast cancer. © 2016 The Authors.
Strategies for the prevention of knee osteoarthritis.
Roos, Ewa M; Arden, Nigel K
2016-02-01
Osteoarthritis (OA) has been thought of as a disease of cartilage that can be effectively treated surgically at severe stages with joint arthroplasty. Today, OA is considered a whole-organ disease that is amenable to prevention and treatment at early stages. OA develops slowly over 10-15 years, interfering with activities of daily living and the ability to work. Many patients tolerate pain, and many health-care providers accept pain and disability as inevitable corollaries of OA and ageing. Too often, health-care providers passively await final 'joint death', necessitating knee and hip replacements. Instead, OA should be viewed as a chronic condition, where prevention and early comprehensive-care models are the accepted norm, as is the case with other chronic diseases. Joint injury, obesity and impaired muscle function are modifiable risk factors amenable to primary and secondary prevention strategies. The strategies that are most appropriate for each patient should be identified, by selecting interventions to correct--or at least attenuate--OA risk factors. We must also choose the interventions that are most likely to be acceptable to patients, to maximize adherence to--and persistence with--the regimes. Now is the time to begin the era of personalized prevention for knee OA.
The elite young athlete: strategies to ensure physical and emotional health
Sabato, Todd M; Walch, Tanis J; Caine, Dennis J
2016-01-01
This article presents a current review of the risk of physical and psychological injury associated with participation in elite youth sport, and suggests strategies to ensure the physical and emotional health of these young athletes. Although there is lack of epidemiological data, especially with regard to psychological injury, preliminary data suggest that the risk of injury is high in this population. While there is lack of incident and follow-up data, there is also concern regarding burnout, disordered eating, and the long-term consequences of injury. Modifiable injury risk factors identified include postural control, competition anxiety, life events, previous injury, and volume of training. There are presently no studies designed to determine the effectiveness of injury prevention measures in elite youth sports. However, there is adequate evidence arising from injury prevention studies of youth sports participants – including neuromuscular training, protective equipment, mental training to enhance self-esteem, and sport rules modification – to prevent injuries in elite youth sports settings. Although not tested, psychosocial prevention strategies such as adoption of task-oriented coping mechanisms, autonomous support from parents, and a proactive organizational approach also show promise in injury prevention.

Childhood and adolescence are particularly vulnerable periods of life to the effects of cardiometabolic risk and later development of atherosclerosis, hypertension, and diabetes mellitus. Developing countries with limited resources suffer most heavily from the consequences of cardiometabolic risk in children and its future implications to the global health burden. A better understanding of mechanisms leading to cardiometabolic risk in early life may lead to more effective prevention and intervention strategies to reduce metabolic stress in children and later disease. Longitudinal "tracking" studies of cardiometabolic risk in children provide a tremendous global resource to direct prevention strategies for cardiovascular disease. In this review, we will summarize the pathophysiology, existing definitions for cardiometabolic risk components in children. Screening and identifying children and adolescents of high cardiometabolic risk and encouraging them and their families through healthy lifestyle changes should be implemented to as a global public health strategy. © 2015 John Wiley & Sons Ltd.

This paper presents the results of theory-based intervention strategies to increase the adoption of a tobacco prevention program. The adoption intervention followed a series of dissemination intervention strategies targeted at 128 school districts in Texas. Informed by Social Cognitive Theory, the intervention provided opportunities for districts to learn about and model themselves after 'successful' school districts that had adopted the program, and to see the potential for social reinforcement through the knowledge that the program had the potential to have an important influence on students' lives. The proportion of districts in the Intervention condition that adopted the program was significantly greater than in the Comparison condition (P < 0.001). Stepwise logistic regression indicated that the variables most closely related to adoption among intervention districts were teacher attitudes toward the innovation and organizational considerations of administrators. Recommendations for the development of effective strategies for the diffusion of innovations are presented.
Prevention and control of blood stream infection using the balanced scorecard approach.

to obtain formulation of an effective and efficient strategy to overcome blood stream infection (BSI). operational research design with qualitative and quantitative approach. The study was divided into two stages. Stage I was an operational research with problem solving approach using qualitative and quantitative method. Stage II was performed using quantitative method, a form of an interventional study on strategy implementation, which was previously established in stage I. The effective and efficient strategy for the prevention and control of infection in neonatal unit Cipto Mangunkusumo (CM) Hospital was established using Balanced Scorecard (BSC) approach, which involved several related processes. the BSC strategy was proven to be effective and efficient in substantially reducing BSI from 52.31°/oo to 1.36°/oo in neonates with birth weight (BW) 1000-1499 g (p=0.025), and from 29.96°/oo to 1.66°/oo in BW 1500-1999 g (p=0.05). Gram-negative bacteria still predominated as the main cause of BSI in CMH Neonatal Unit. So far, the sources of the microorganisms were thought to be from the environment of treatment unit (tap water filter and humidifying water in the incubator). Significant reduction was also found in neonatal mortality rate weighing 1000-1499 g at birth, length of stay, hospitalization costs, and improved customer satisfaction. effective and efficient infection prevention and control using BSC approach could significantly reduce the rate of BSI. This approach may be applied for adult patients in intensive care unit with a wide range of adjustment.

This paper reports a review that assessed the effectiveness and characteristics of fall prevention interventions implemented in hospitals. A multi-systemic fall prevention model that establishes a practical framework was developed from the evidence. Falls occur through complex interactions between patient-related and environmental risk factors, suggesting a need for multifaceted fall prevention approaches that address both factors. We searched Medline, CINAHL, PsycInfo and the Web of Science databases for references published between January 1990 and June 2009 and scrutinized secondary references from acquired papers. Due to the heterogeneity of interventions and populations, we conducted a quantitative systematic review without a meta-analysis and used a narrative summary to report findings. From the review, three distinct characteristics of fall prevention interventions emerged: (1) the physical environment, (2) the care process and culture and (3) technology. While clinically significant evidence shows the efficacy of environment-related interventions in reducing falls and fall-related injuries, the literature identified few hospitals that had introduced environment-related interventions in their multifaceted fall intervention strategies. Using the multi-systemic fall prevention model, hospitals should promote a practical strategy that benefits from the collective effects of the physical environment, the care process and culture and technology to prevent falls and fall-related injuries. By doing so, they can more effectively address the various risk factors for falling and therefore, prevent falls. Studies that test the proposed model need to be conducted to establish the efficacy of the model in practice. © 2011 The Authors. Journal of Advanced Nursing © 2011 Blackwell Publishing Ltd.

Actions to prevent early onset disease in neonates are based on different strategies including administering antibiotic prophylaxis during labour in case of 1) maternal GBS colonisation (screening strategy), 2) identified risk factors (risk-based strategy) or 3) a combination of these two conditions (maternal GBS colonisation and identified risk factors: combination strategy and the Dutch guideline). Low adherence to guidelines preventing EOGBS has been reported. Each strategy has drawbacks and clinical outcomes are affected by care providers' and women's adherence. The actual impact of any preventive strategy is the product of efficacy of the strategy and the level of implementation. In order to reduce neonatal death due to EOGBS by developing the optimal guideline, we analysed barriers and facilitators of current used strategies. Focus group and personal interviews with care providers and women were performed. Impeding and enhancing factors in adherence to the preventive strategies were discussed and scored using the Measurement Instrument for Determinants of Innovations (MIDI) and analysed by two independent researchers. Overall, care providers identified 3.6 times more factors that would impede (n = 116) rather than facilitate (n = 32) adherence to the preventive strategies. 28% facilitative factors were reported in relation to the combination strategy and 86% impeding factors in relation to the Dutch guideline. The most preferred strategy was the combination strategy by 74% of the care providers and by 86% of the women. We obtained a detailed understanding of factors that influence adherence to preventive strategies. This insight can be used to develop implementation activities to improve the uptake of new strategies. The trial is registered in the Dutch Trial Register NTR3965 .

Medication-induced side effects, called untoward effects by pharmacologists, can be a problem with any medication. Few therapies are perfectly specific for the desired physiological activity; rather they act on multiple biological targets and result in multiple physiological effects. There are several strategies that are employed to prevent, alleviate or counteract medication-induced side effects. The administered dose may be optimized to the lowest possible amount that provides the desired therapeutic effect, with the expectation that untoward effects will be minimized by a lower dose. Empirical trials of different therapies for a particular medical problem may be used in the hopes of finding a drug with minimal side effects for a particular patient, or at least of finding a set of side effects that the patient considers tolerable. If these two strategies have been exhausted, it may be possible to administer another medication to block or ameliorate side effects. A recent search of published scientific literature has revealed that there are medications used in spaceflight that seem to be associated with a significant number of reports of untoward effects. To prevent future medical problems and to improve the well-being and productivity of crew members, it would be best to eliminate (or at least reduce) untoward effects. Reports from the literature will be examined, with the aim of identifying a strategy for reducing untoward effects.

This study evaluated the relative efficacy of strategies for the prevention of multidrug-resistant gram-negative bacteria (MDR-GNB) in adult intensive care units (ICUs). A systematic review and network meta-analysis was performed; searches of the Cochrane Library, PubMed, Embase, and CINAHL (Cumulative Index to Nursing and Allied Health Literature) included all randomized controlled trials and observational studies conducted in adult patients hospitalized in ICUs and evaluating standard care (STD), antimicrobial stewardship program (ASP), environmental cleaning (ENV), decolonization methods (DCL), or source control (SCT), simultaneously. The primary outcomes were MDR-GNB acquisition, colonization, and infection; secondary outcome was ICU mortality. Of 3805 publications retrieved, 42 met inclusion criteria (5 randomized controlled trials and 37 observational studies), involving 62068 patients (median age, 58.8 years; median APACHE [Acute Physiology and Chronic Health Evaluation] II score, 18.9). The majority of studies reported extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae and MDR Acinetobacter baumannii. Compared with STD, a 4-component strategy composed of STD, ASP, ENV, and SCT was the most effective intervention (rate ratio [RR], 0.05 [95% confidence interval {CI}, .01-.38]). When ENV was added to STD+ASP or SCT was added to STD+ENV, there was a significant reduction in the acquisition of MDR A. baumannii (RR, 0.28 [95% CI, .18-.43] and 0.48 [95% CI, .35-.66], respectively). Strategies with ASP as a core component showed a statistically significant reduction the acquisition of ESBL-producing Enterobacteriaceae (RR, 0.28 [95% CI, .11-.69] for STD+ASP+ENV and 0.23 [95% CI, .07-.80] for STD+ASP+DCL). A 4-component strategy was the most effective intervention to prevent MDR-GNB acquisition. As some strategies were differential for certain bacteria, our study highlighted the need for further evaluation of the most effective prevention strategies. © The Author 2017.

Over 1.1 million Americans are living with human immunodeficiency virus (HIV), and African-American youth and young adults are disproportionately affected. Condoms are the most effective prevention tool, yet data regarding condom use patterns for African-American college youth are lacking. To inform and strengthen HIV prevention strategies with African-American college-age youth, we surveyed students attending 24 historically Black colleges and universities regarding condom use patterns. Students were administered anonymous questionnaires online to explore knowledge, attitudes, and practices related to condom use during last sexual intercourse (LSI). Among 824 sexually active respondents (51.8% female, median age 20 years, 90.6% heterosexuals), 526 (63.8%) reported condom use during LSI. Students who used condoms for disease prevention, whose mothers completed high school or had some college education or completed college were more likely to have used a condom during LSI. Spontaneity of sexual encounters, not feeling at risk of HIV, and partner-related perceptions were associated with condom non-use during LSI (p<0.05). Over a third of our college youth sample did not use a condom during LSI and may benefit from increased condom education efforts. These efforts should highlight condoms' effectiveness in protection from HIV. Future HIV education and prevention strategies with similar groups of young adults should explore the implications of maternal education, clarify perceptions of HIV risk, and consider strategies that increase consistent condom use to interrupt sexual transmission of HIV.

Objective To compare the use of four different social media sites to recruit men who have sex with men (MSM) and transgender women to a phase 2b HIV prevention vaccine trial, HVTN 505. Design Retrospective, observational study. Methods The University of Pennsylvania HIV Vaccine Trials Unit (Penn HVTU) employed street outreach and online recruitment methods to recruit participants for HVTN 505 using a combination of national recruitment images/messages with Philadelphia-specific language and imagery. We compared the efficiency (number of enrolled participants per number of completed phone screens) and effectiveness (number of enrolled participants per time interval employed) of each strategy, as well as the demographics and risk behaviors of the populations. Results Online recruitment strategies populated 37% (71/191) of trial participants at our site. Among the four social media strategies employed, 45.1% (32/71) were enrolled through Facebook, 16.9% (12/71) through Craigslist, 15.5% (11/71) through a web-based marketing company (WBMC), and 22.5% (16/71) via GRINDR. The number of participants enrolled per month of strategy and the months the strategy was employed were Facebook - 32(33 months), Craigslist - 12(33 months), WBMC -11(6 months), and GRINDR – 16(0.56 months). In-person and online recruitment strategies yielded participants of similar demographics and levels of risk behavior. Conclusion Use of several social media recruitment modalities produced large numbers of MSM engaging in high risk behavior and willing to participate in an HIV prevention vaccine trial. In comparison to other social media and online strategies, recruitment via GRINDR was the most effective. PMID:28526330

To apply the Theory of Planned Behaviour to examine the relationship between the constructs of background factors and beliefs towards using policy, systems and environmental (PSE) strategies and reported use of PSE strategies to prevent obesity by a group of professional nutrition educators. Cross-sectional study using self-reported survey. Cooperative Extension in New York, USA. Nutrition educators (n 58); survey response rate 100 %. Nutrition educators' reported use of PSE strategies to prevent obesity were positively associated with background factors of their community networking and number of staff they managed, their belief of other people's expectations of them to make PSE changes and the belief that their communities were ready to use PSE strategies; and negatively associated with their belief that individual-level factors contributed to obesity. The relationships among these variables were complicated and their use of PSE strategies occurred only when they utilized their professional networks at a moderately high level (above mean of 5·3 on a scale of 1-7), given that their community was also ready to use PSE strategies. Nutrition educators' use of PSE strategies depends on several internal and external factors. Community networking needs to be emphasized as one of the most significant factors contributing to nutrition educators' work in this area. Organizational and community support should be in place in order to facilitate nutrition educators' effective use of PSE strategies.
A qualitative study of rural black adolescents' perspectives on primary STD prevention strategies.

Primary STD prevention relies on five key strategies: practicing abstinence, choosing low-risk partners, discussing partners' sexual history, using condoms consistently and not having multiple partners. Few studies have examined all of these strategies simultaneously, and few have focused on rural black adolescents, whose rates of early sexual initiation and STDs are among the highest in the nation. In 2006, a sample of 37 black adolescents (20 female, 17 male) from two rural North Carolina counties participated in focus groups that explored their understanding of how primary prevention strategies reduce STD transmission, the common barriers they encounter in trying to adopt these strategies and the risk reduction strategies that they employ. Transcripts were analyzed using a grounded theory approach. Adolescents understood how primary prevention strategies reduce STD transmission. However, they perceived sex as normal and abstinence as unlikely during adolescence. Furthermore, they considered the remaining primary prevention strategies difficult to implement because these strategies depend on partner cooperation and incorrectly assume that STD prevention is paramount when adolescents make sexual decisions. Adolescents reported using alternative strategies to reduce their STD risk; the most commonly used approaches were indirect assessments of partner characteristics (e.g., evaluating partners' physical appearance and sexual history) and STD testing (to identify and treat infections). Adolescents try to reduce their STD risk, but do so by using ineffective practices. Promoting primary prevention strategies requires helping adolescents to identify opportunities to successfully employ these strategies. Copyright © 2012 by the Guttmacher Institute.

Prevention strategies have made a major contribution to the considerable successes in reductions in cardiovascular disease and cancer mortality seen in recent decades. However, in the field of psychiatry, similar population-level initiatives in the prevention of common mental disorders, depression and anxiety, are noticeably lacking. This paper aims to provide a brief overview of the existing literature on the topic of the prevention of common mental disorders and a commentary regarding the way forward for prevention research and implementation. This commentary considers what we currently know, what we might learn from the successes and failures of those working in prevention of other high prevalence health conditions, and where we might go from here. Taking cognisance of previous preventive models, this commentary additionally explores new opportunities for preventive approaches to the common mental disorders. The consensus from a large body of evidence supports the contention that interventions to prevent mental disorders across the lifespan can be both effective and cost-effective. However, funding for research in the area of prevention of common mental disorders is considerably lower than that for research in the areas of treatment, epidemiology and neurobiology. Thus, there is a clear imperative to direct funding towards prevention research to redress this imbalance. Future prevention interventions need to be methodologically rigorous, scalable to the population level and include economic evaluation. Evidence-based knowledge translation strategies should be developed to ensure that all stakeholders recognise preventing mental disorders as an imperative, with appropriate resources directed to this objective. There has been a recent expansion of research into potentially modifiable risk factors for depression, and it is now timely to make a concerted effort to advance the field of prevention of common mental disorders.

Background With 249,007 new leprosy patients detected globally in 2008, it remains necessary to develop new and effective interventions to interrupt the transmission of M. leprae. We assessed the economic benefits of single dose rifampicin (SDR) for contacts as chemoprophylactic intervention in the control of leprosy. Methods We conducted a single centre, double blind, cluster randomised, placebo controlled trial in northwest Bangladesh between 2002 and 2007, including 21,711 close contacts of 1,037 patients with newly diagnosed leprosy. We gave a single dose of rifampicin or placebo to close contacts, with follow-up for four years. The main outcome measure was the development of clinical leprosy. We assessed the cost effectiveness by calculating the incremental cost effectiveness ratio (ICER) between the standard multidrug therapy (MDT) program with the additional chemoprophylaxis intervention versus the standard MDT program only. The ICER was expressed in US dollars per prevented leprosy case. Findings Chemoprophylaxis with SDR for preventing leprosy among contacts of leprosy patients is cost-effective at all contact levels and thereby a cost-effective prevention strategy. In total, $6,009 incremental cost was invested and 38 incremental leprosy cases were prevented, resulting in an ICER of $158 per one additional prevented leprosy case. It was the most cost-effective in neighbours of neighbours and social contacts (ICER $214), slightly less cost-effective in next door neighbours (ICER $497) and least cost-effective among household contacts (ICER $856). Conclusion Chemoprophylaxis with single dose rifampicin given to contacts of newly diagnosed leprosy patients is a cost-effective intervention strategy. Implementation studies are necessary to establish whether this intervention is acceptable and feasible in other leprosy endemic areas of the world. PMID:21072235

Community Health Workers are widely utilised in low- and middle-income countries and may be an important tool in reducing maternal and child mortality; however, evidence is lacking on their effectiveness for specific types of programmes, specifically programmes of a preventive nature. This review reports findings on a systematic review analysing effectiveness of preventive interventions delivered by Community Health Workers for Maternal and Child Health in low- and middle-income countries. A search strategy was developed according to the Evidence for Policy and Practice Information and Co-ordinating Centre's (EPPI-Centre) guidelines and systematic searching of the following databases occurred between June 8-11th, 2012: CINAHL, Embase, Ovid Nursing Database, PubMed, Scopus, Web of Science and POPLINE. Google, Google Scholar and WHO search engines, as well as relevant systematic reviews and reference lists from included articles were also searched. Inclusion criteria were: i) Target beneficiaries should be pregnant or recently pregnant women and/or children under-5 and/or caregivers of children under-5; ii) Interventions were required to be preventive and delivered by Community Health Workers at the household level. No exclusion criteria were stipulated for comparisons/controls or outcomes. Study characteristics of included articles were extracted using a data sheet and a peer tested quality assessment. A narrative synthesis of included studies was compiled with articles being coded descriptively to synthesise results and draw conclusions. A total of 10,281 studies were initially identified and through the screening process a total of 17 articles detailing 19 studies were included in the review. Studies came from ten different countries and consisted of randomized controlled trials, cluster randomized controlled trials, before and after, case control and cross sectional studies. Overall quality of evidence was found to be moderate. Five main preventive intervention categories emerged: malaria prevention, health education, breastfeeding promotion, essential newborn care and psychosocial support. All categories showed some evidence for the effectiveness of Community Health Workers; however they were found to be especially effective in promoting mother-performed strategies (skin to skin care and exclusive breastfeeding). Community Health Workers were shown to provide a range of preventive interventions for Maternal and Child Health in low- and middle-income countries with some evidence of effective strategies, though insufficient evidence is available to draw conclusions for most interventions and further research is needed.

Despite over a decade of research and programming, little evidence is available on effective strategies to reduce HIV risks among Central American men who have sex with men (MSM). The Pan-American Social Marketing Organization (PASMO) and partners are implementing a HIV Combination Prevention Program to provide key populations with an essential package of prevention interventions and services: 1) behavioral, including interpersonal communications, and online outreach; 2) biomedical services including HIV testing and counseling and screening for STIs; and 3) complementary support, including legal support and treatment for substance abuse. Two years into implementation, we evaluated this program's effectiveness for MSM by testing whether exposure to any or a combination of program components could reduce HIV risks. PASMO surveyed MSM in 10 cities across Guatemala, El Salvador, Nicaragua, Costa Rica, and Panama in 2012 using respondent-driven sampling. We used coarsened exact matching to create statistically equivalent groups of men exposed and non-exposed to the program, matching on education, measures of social interaction, and exposure to other HIV prevention programs. We estimated average treatment effects of each component and all combined to assess HIV testing and condom use outcomes, using multivariable logistic regression. We also linked survey data to routine service data to assess program coverage. Exposure to any program component was 32% in the study area (n = 3531). Only 2.8% of men received all components. Men exposed to both behavioral and biomedical components were more likely to use condoms and lubricant at last sex (AOR 3.05, 95% CI 1.08, 8.64), and those exposed to behavioral interventions were more likely to have tested for HIV in the past year (AOR 1.76, 95% CI 1.01, 3.10). PASMO's strategies to reach MSM with HIV prevention programming are still achieving low levels of population coverage, and few men are receiving the complete essential package. However, those reached are able to practice HIV prevention. Combination prevention is a promising approach in Central America, requiring expansion in coverage and intensity.

Objective To model the long term effectiveness and cost effectiveness of daily dark chocolate consumption in a population with metabolic syndrome at high risk of cardiovascular disease. Design Best case scenario analysis using a Markov model. Setting Australian Diabetes, Obesity and Lifestyle study. Participants 2013 people with hypertension who met the criteria for metabolic syndrome, with no history of cardiovascular disease and not receiving antihypertensive therapy. Main outcome measures Treatment effects associated with dark chocolate consumption derived from published meta-analyses were used to determine the absolute number of cardiovascular events with and without treatment. Costs associated with cardiovascular events and treatments were applied to determine the potential amount of funding required for dark chocolate therapy to be considered cost effective. Results Daily consumption of dark chocolate (polyphenol content equivalent to 100 g of dark chocolate) can reduce cardiovascular events by 85 (95% confidence interval 60 to 105) per 10 000 population treated over 10 years. $A40 (£25; €31; $42) could be cost effectively spent per person per year on prevention strategies using dark chocolate. These results assume 100% compliance and represent a best case scenario. Conclusions The blood pressure and cholesterol lowering effects of dark chocolate consumption are beneficial in the prevention of cardiovascular events in a population with metabolic syndrome. Daily dark chocolate consumption could be an effective cardiovascular preventive strategy in this population. PMID:22653982

Every company situated within a chemical cluster faces domino effect risks, whose magnitude depends on every company's own risk management strategies and on those of all others. Preventing domino effects is therefore very important to avoid catastrophes in the chemical process industry. Given that chemical companies are interlinked by domino effect accident links, there is some likelihood that even if certain companies fully invest in domino effects prevention measures, they can nonetheless experience an external domino effect caused by an accident which occurred in another chemical enterprise of the cluster. In this article a game-theoretic approach to interpret and model behaviour of chemical plants within chemical clusters while negotiating and deciding on domino effects prevention investments is employed.
Rose's population strategy of prevention need not increase social inequalities in health.
McLaren, Lindsay; McIntyre, Lynn; Kirkpatrick, Sharon
2010-04-01
Geoffrey Rose's 1985 paper, Sick individuals and sick populations, continues to spark debate and discussion. Since this original publication, there have been two notable challenges to Rose's population strategy of prevention. First, identification of high-risk individuals has improved considerably in accuracy, which some believe obviates the need for population-wide prevention strategies. Secondly, and more recently, it has been suggested that population strategies of prevention may inadvertently worsen social inequalities in health. We argue that population prevention will not necessarily worsen social inequalities in health, and the likelihood of it doing so will depend on whether the prevention strategy is more structural (targets conditions in which behaviours occur) or agentic (targets behaviour change among individuals) in nature. Also, there are potential drawbacks of approaches that focus on discrete populations (i.e. high risk or vulnerable) that need to be considered when selecting a strategy. Although Rose's ideas need to be continually scrutinized, his population strategy of prevention still holds considerable merit for improving population health and narrowing social inequalities in health.

Nonsteroidal anti-inflammatory drugs (NSAIDs) increase the risk of peptic ulcer disease by 5- to 7-fold in the first 3 months of treatment. This study examined the relative cost-effectiveness of different strategies for the primary prevention of NSAID-induced ulcers in patients that are starting NSAID treatment. A decision analysis model was developed to compare the cost-effectiveness of 6 prophylactic strategies relative to no prophylaxis for patients 65 years of age starting a 3-month course of NSAIDs: (1) testing for Helicobacter pylori infection and treating those with positive tests; (2) empiric treatment of all patients for Helicobacter pylori; (3) conventional-dose histamine2 receptor antagonists; (4) high-dose histamine2 receptor antagonists; (5) misoprostol; and (6) omeprazole. Costs were estimated from 1997 Medicare reimbursement schedules and the Drug Topics Red Book. Empiric treatment of Helicobacter pylori with bismuth, metronidazole, and tetracycline was cost-saving in the baseline analysis. Selective treatment of Helicobacter pylori, misoprostol, omeprazole, and conventional-dose or high-dose histamine2 receptor antagonists cost $23,800, $46,100, $34,400, and $15,600 or $21,500 per year of life saved, respectively, relative to prophylaxis. The results were sensitive to the probability of an ulcer, the probability and mortality of ulcer complications, and the cost of, efficacy of, and compliance with prophylaxis. The cost-effectiveness estimates did not change substantially when costs associated with antibiotic resistance of Helicobacter pylori were incorporated. Several strategies for primary prevention of NSAID-induced ulcers in patients starting NSAIDs were estimated to have acceptable cost-effectiveness relative to prophylaxis. Empirically treating all patients for Helicobacter pylori with bismuth, metronidazole, and tetracycline was projected to be cost-saving in older patients.

We discuss the role of implementation science in cancer and summarize the need for this perspective. Following a summary of key implementation science principles and lessons learned, we review the literature on implementation of cancer prevention and control activities across the continuum from prevention to palliative care. We identified 10 unique relevant reviews, four of which were specific to cancer. Multicomponent implementation strategies were found to be superior to single-component interventions, but it was not possible to draw conclusions about specific strategies or the range of conditions across which strategies were effective. Particular gaps identified include the need for more studies of health policies and reports of cost, cost-effectiveness, and resources required. Following this review, we summarize the types of evidence needed to make research findings more actionable and discuss emerging implementation science opportunities for psychological research on cancer prevention and control. These include innovative study designs (i.e., rapid learning designs, simulation modeling, comparative effectiveness, pragmatic studies, mixed-methods research) and measurement science (i.e., development of context-relevant measures; practical, longitudinal measures to gauge improvement; cost-effectiveness data; and harmonized patient report data). We conclude by identifying a few grand challenges for psychologists that if successfully addressed would accelerate integration of evidence into cancer practice and policy more consistently and rapidly.

A U.S. Biodefense Strategy Primer
DOE Office of Scientific and Technical Information (OSTI.GOV)
Poulin, D
2009-05-11
The anthrax mailings that followed the attacks of September 11, 2001 highlighted the need for a comprehensive national strategy to prevent, prepare for, respond to, and mitigate the effects of biological attacks. The goal of U.S. biodefense strategy is to reduce the likelihood of a future biological event, improve overall U.S. public health security, and minimize the economic and social disruption of a biological incident. Presidential communications, federal legislation, and executive agency planning documents provide the foundation for this strategy. Central to current U.S. biodefense strategy is the 2004 Homeland Security Presidential Directive (HSPD) 10, Biodefense for the 21st Century,more » which states that ''the United States will use all means necessary to prevent, protect against, and mitigate biological weapons attacks perpetrated against our homeland and our global interests.'' HSPD-10 also sets forth four pillars of U.S. biodefense: {sm_bullet} Threat awareness includes timely, accurate, and relevant intelligence, threat assessment, and the anticipation of future threats. {sm_bullet} Prevention and protection involve continuing and expanding efforts to limit access to agents, technologies, and knowledge to certain groups and countries as well as protecting critical infrastructure from the effects of biological attacks. {sm_bullet} Surveillance and detection provide early warning or recognition of biological attacks to permit a timely response and mitigation of consequences as well as attribution. {sm_bullet} Response and recovery include pre-attack planning and preparedness, capabilities to treat casualties, risk communications, physical control measures, medical countermeasures, and decontamination capabilities.« less
Global strategies for cervical cancer prevention.
Pimple, Sharmila; Mishra, Gauravi; Shastri, Surendra
2016-02-01
Cervical cancer still remains the fourth most common cancer, affecting women worldwide with large geographic variations in cervical cancer incidence and mortality rates. There exist vast disparities in cervix cancer control and prevention efforts globally. The present review addresses the current developments in cervical cancer prevention and control across both high-income countries and low-middle income countries and attempts to identify new strategies that might help address the gaps in cervical cancer care disparities globally. Paradigms for cervix cancer screening are changing in high-resource settings from cytology-based screening to adoption of molecular screening and cotesting to achieve program effectiveness. Low-middle income countries with larger burden of cervical cancer continue to face financial and logistic limitations to make both cervix cancer screening and human papillomavirus vaccine available to their populations. Alternative low-cost screening technologies, operationally feasible implementation strategies, reduction of cost of procurement and delivery approaches for human papillomavirus vaccine need assessment to decrease cancer care disparities. Efforts directed toward cervix cancer prevention and early detection for improvements in cervical cancer outcomes of incidence and mortality have to be proportionately matched by access to acceptable standards of cancer care.
Reflecting and shaping the discourse: the role of music in AIDS communication in Tanzania.
Bastien, Sheri
2009-04-01
Failure to recognize the importance of oral traditions in Africa and the potential of music and song for stimulating social and behavior change would represent a missed opportunity in HIV prevention strategies. Local narratives concerning AIDS are often utilized in popular songs and constitute rich sources of contextual information about the epidemic that have thus far been un- or underutilized in HIV prevention strategies. Endogenously conceived messages delivered via a channel such as music increase the likelihood of messages being contextually appropriate and culturally engaging. This form of media also presents the greatest opportunity for wide dissemination. Drawing on field work conducted in the Kilimanjaro region, this paper presents examples of how music and musicians in Tanzania reflect and potentially shape AIDS discourse. Three broad recurrent themes addressed in songs are discussed: AIDS metaphors, stigma and broader HIV prevention messages. By tapping into the wealth of information about AIDS discourse contained within popular songs, and by recognizing musicians as potential opinion leaders and agents of social change, the effectiveness of prevention strategies may be increased.
A knock to the system: A new sociotechnical systems approach to sport-related concussion.

Broader contextual factors that influence concussion management have tended to be overlooked. To address this, the present study used a sociotechnical systems approach to identify perceived responsibilities and applied strategies for three domains of concussion management (i.e., prevention, identification and treatment). Participants were 118 members of the community rugby union system in Australia (69.2% male). Participants from throughout the rugby system (e.g., players, parents, coaches, club management) were asked open-ended questions about their perceived responsibilities and the strategies they use for concussion management. It was found that (a) proper training, technique correction and education were recurrent prevention themes; (b) the majority of key stakeholders felt that they could consistently identify concussion; however, medical aids (medics) were the only system actors who stated a responsibility to use standardised concussion assessment measures and (c) less than one third of the respondents indicated their involvement in treating concussion. This study identifies specific junctures in the system that prevents effective concussion management strategies. A sociotechnical systems approach improves the understanding of concussion prevention, and management beliefs and behaviours.

Despite many recommended strategies for obesity prevention during infancy, effectively delivering recommendations to parents in clinical settings is challenging, especially among high-risk populations. This study describes and compares mothers' and clinicians' priorities for obesity prevention during infancy, to facilitate more-effective obesity prevention messaging. A discrete choice experiment using maximum difference scaling was administered in 2013 and analyzed in 2013-2014. Twenty-nine low-income, obese mothers of infants and 30 pediatric clinicians from three urban primary care practices rated the relative importance of 16 items relevant to obesity prevention during infancy, in response to this question: Which topic would be most helpful [for new mothers] to learn about to prevent your [their] child from becoming overweight? Response options encompassed the domains of feeding, sleep, parenting (including physical activity and screen time), and maternal self-care. Mothers (all Medicaid-enrolled and black; mean age, 27 years; mean BMI, 35 kg/m(2)) and clinicians (97% female, 87% pediatricians, 13% nurse practitioners) both highly prioritized recognizing infant satiety and hunger cues, and appropriate feeding volume. Mothers rated infant physical activity and maintaining regular routines as 3.5 times more important than clinicians did (p<0.001). Clinicians rated breastfeeding as 3.4 times more important than mothers did (p<0.001). Neither group prioritized learning about screen time or maternal self-care. Low-income, obese, black mothers of infants highly prioritized learning about many effective obesity prevention strategies, including recognizing hunger and satiety cues, promoting infant activity, and maintaining regular routines. Clinicians may frame preventive guidance to be responsive to these priorities. Copyright © 2016 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

Among the existing sexual assault prevention efforts on college campuses, few use mass communication strategies designed to simultaneously entertain and educate. Although many entertainment-education efforts are guided by social cognitive theory, other theories may be useful in entertainment-education design. Previous research has found that social cognitive theory and social norms theory can successfully influence participants' perceived norms and efficacy related to sexual assault reduction; however, whether such results can be replicated in a naturalistic setting and the extent to which the guiding theoretical foundation may influence outcomes remain unknown. We used a pre- and posttest field experiment with college students in residence halls to assess how different theoretical foundations may influence effects. Over the course of a semester, the participants viewed eight mini-magazines developed using (1) social cognitive theory, (2) social norms theory, (3) a combination of both theoretical frameworks, or (4) a control condition with no sexual assault prevention messaging. Participants in the combined content condition had greater levels of self-efficacy related to sexual assault prevention and more accurate norm perceptions. There were also effects for the mini-magazines developed with only one theoretical framework. Overall, we found that multiple theories can effectively guide entertainment-education message development.

Prevention of hospital-acquired pressure ulcers requires the implementation of evidence-based interventions. A quality improvement project was conducted to provide nurses with data on the frequency with which pressure ulcer prevention interventions were performed as measured by documentation. Documentation reports provided feedback to stakeholders, triggering reminders and reeducation. Intervention reports and modifications to the documentation system were effective both in increasing the documentation of pressure ulcer prevention interventions and in decreasing the number of avoidable hospital-acquired pressure ulcers.
Patient participation in pressure injury prevention: giving patient's a voice.

Pressure injuries burden patients and healthcare organisations, with some preventative practices having little impact on prevalence reduction. Patient participation in care may be an effective pressure injury prevention strategy, yet patient preferences are unknown. The aim of this interpretive study was to describe patients' perceptions of their current and future role in pressure injury prevention. Semi-structured interviews were conducted with 20 adult inpatients recruited from four medical units, at two Australian metropolitan hospitals. Interview data were analysed using content analysis, with three categories emerging: 'experiencing pressure injuries'; 'participating in pressure injury prevention'; and 'resourcing pressure injury prevention and treatment'. These categories reflect the complex nature of participants' pressure injury experience. The findings suggest participants gather pressure injury knowledge from first-hand and vicarious experience; knowledge they bring to hospital. Most participants preferred a proactive pressure injury prevention role. Many identified barriers in the healthcare environment that impeded their participation and affected their experience of pressure injuries and pressure injury prevention. If patient participation as a pressure injury prevention strategy is to be considered, nurses and organisations need to view patients as partners. © 2013 Nordic College of Caring Science.

Nursing homes for older people provide an environment likely to promote the acquisition and spread of meticillin-resistant Staphylococcus aureus (MRSA), putting residents at increased risk of colonisation and infection. It is recognised that infection prevention and control strategies are important in preventing and controlling MRSA transmission. To determine the effects of infection prevention and control strategies for preventing the transmission of MRSA in nursing homes for older people. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2011, Issue 2), the Cochrane Wounds Group Specialised Register (searched May 27th, 2011). We also searched Ovid MEDLINE (from 1950 to April Week 2 2011), OVID MEDLINE (In-process and Other Non-Indexed Citations, April 26th 2011) Ovid EMBASE (1980 to 2011 Week 16), EBSCO CINAHL (1982 to April 21st 2011), DARE (1992 to 2011, week 16), Web of Science (1981 to May 2011), and the Health Technology Assessment (HTA) website (1988 to May 2011). Research in progress was sought through Current Clinical Trials (www.controlled-trials.com), Medical Research Council Research portfolio, and HSRPRoj (current USA projects). All randomised and controlled clinical trials, controlled before and after studies and interrupted time series studies of infection prevention and control interventions in nursing homes for older people were eligible for inclusion. Two review authors independently reviewed the results of the searches. Another review author appraised identified papers and undertook data extraction which was checked by a second review author. For this second update only one study was identified, therefore it was not possible to undertake a meta-analysis. A cluster randomised controlled trial in 32 nursing homes evaluated the effect of an infection control education and training programme on MRSA prevalence. The primary outcome was MRSA prevalence in residents and staff, and a change in infection control audit scores which measured adherence to infection control standards. At the end of the 12 month study, there was no change in MRSA prevalence between intervention and control sites, while mean infection control audit scores were significantly higher in the intervention homes compared with control homes. There is a lack of research evaluating the effects on MRSA transmission of infection prevention and control strategies in nursing homes. Rigorous studies should be conducted in nursing homes, to test interventions that have been specifically designed for this unique environment.

Occupational slips, trips and falls on the same level (STFL) result in substantial injuries worldwide. This paper summarises the state of science regarding STFL, outlining relevant aspects of epidemiology, biomechanics, psychophysics, tribology, organisational influences and injury prevention. This review reaffirms that STFL remain a major cause of workplace injury and STFL prevention is a complex problem, requiring multi-disciplinary, multi-faceted approaches. Despite progress in recent decades in understanding the mechanisms involved in STFL, especially slipping, research leading to evidence-based prevention practices remains insufficient, given the problem scale. It is concluded that there is a pressing need to develop better fall prevention strategies using systems approaches conceptualising and addressing the factors involved in STFL, with considerations of the full range of factors and their interactions. There is also an urgent need for field trials of various fall prevention strategies to assess the effectiveness of different intervention components and their interactions. Practitioner Summary: Work-related slipping, tripping and falls on the same level are a major source of occupational injury. The causes are broadly understood, although more attention is needed from a systems perspective. Research has shown preventative action to be effective, but further studies are required to understand which aspects are most beneficial.
Behavioural strategies to reduce HIV transmission: how to make them work better
Coates, Thomas J; Richter, Linda; Caceres, Carlos
2009-01-01
This paper makes five key points. First is that the aggregate effect of radical and sustained behavioural changes in a sufficient number of individuals potentially at risk is needed for successful reductions in HIV transmission. Second, combination prevention is essential since HIV prevention is neither simple nor simplistic. Reductions in HIV transmission need widespread and sustained efforts, and a mix of communication channels to disseminate messages to motivate people to engage in a range of options to reduce risk. Third, prevention programmes can do better. The effect of behavioural strategies could be increased by aiming for many goals (eg, delay in onset of first intercourse, reduction in number of sexual partners, increases in condom use, etc) that are achieved by use of multilevel approaches (eg, couples, families, social and sexual networks, institutions, and entire communities) with populations both uninfected and infected with HIV. Fourth, prevention science can do better. Interventions derived from behavioural science have a role in overall HIV-prevention efforts, but they are insufficient when used by themselves to produce substantial and lasting reductions in HIV transmission between individuals or in entire communities. Fifth, we need to get the simple things right. The fundamentals of HIV prevention need to be agreed upon, funded, implemented, measured, and achieved. That, presently, is not the case. PMID:18687459

Vaccines and immunization strategies for dengue prevention
Liu, Yang; Liu, Jianying; Cheng, Gong
2016-01-01
Dengue is currently the most significant arboviral disease afflicting tropical and sub-tropical countries worldwide. Dengue vaccines, such as the multivalent attenuated, chimeric, DNA and inactivated vaccines, have been developed to prevent dengue infection in humans, and they function predominantly by stimulating immune responses against the dengue virus (DENV) envelope (E) and nonstructural-1 proteins (NS1). Of these vaccines, a live attenuated chimeric tetravalent DENV vaccine developed by Sanofi Pasteur has been licensed in several countries. However, this vaccine renders only partial protection against the DENV2 infection and is associated with an unexplained increased incidence of hospitalization for severe dengue disease among children younger than nine years old. In addition to the virus-based vaccines, several mosquito-based dengue immunization strategies have been developed to interrupt the vector competence and effectively reduce the number of infected mosquito vectors, thus controlling the transmission of DENV in nature. Here we summarize the recent progress in the development of dengue vaccines and novel immunization strategies and propose some prospective vaccine strategies for disease prevention in the future.

Therapeutic options for diseases due to potential viral agents of bioterrorism.
Bronze, Michael S; Greenfield, Ronald A
2003-02-01
The etiologic agents of smallpox and viral hemorrhagic fever have emerged as potential agents of bioterrorism due to their virulence, potential for human to human dissemination and limited strategies for treatment and prevention. Cidofovir has shown significant promise in animal models, and limited case reports in humans are encouraging. Ribavirin is the treatment of choice for certain hemorrhagic fever viral infections, but has no current application to Ebola and Marburg infections. Current vaccine strategies for smallpox are effective, but carry significant risk for complications. Licensed vaccines for hemorrhagic fever viruses are limited to yellow fever, but animal studies are promising. Genomic analysis of the viral pathogen and the animal model response to infection may provide valuable information enabling the development of novel treatment and prevention strategies. Current knowledge of these strategies is reviewed.
Primary Prevention of Sexual Violence in Aotearoa New Zealand.
Dickson, Sandra; Willis, Gwenda M
2017-03-01
The extensive and sometimes profoundly damaging effects of sexual violence and large numbers of victims necessitate dedicated attention to primary prevention efforts. Few studies have examined the scope of current prevention activities or their fit with empirical research into effective prevention strategies. The current article presents findings from a survey of primary prevention activities in non-Māori and bicultural communities within Aotearoa New Zealand. Forty-four respondents representing 42 agencies responded to a comprehensive survey that canvased types of sexual violence primary prevention activities undertaken, sexual violence primary prevention programs, and barriers and supports to sexual violence prevention work. Consistent with findings from previous international surveys, the focus of primary prevention work in New Zealand was on sexual violence education and increasing awareness. Findings are discussed in the context of the sexual violence prevention literature and what works in prevention more broadly to help identify promising initiatives as well as gaps in current practices. Recommendations for advancing sexual violence primary prevention research are also provided.
Modification of the surfaces of medical devices to prevent microbial adhesion and biofilm formation.
Desrousseaux, C; Sautou, V; Descamps, S; Traoré, O
2013-10-01
The development of devices with surfaces that have an effect against microbial adhesion or viability is a promising approach to the prevention of device-related infections. To review the strategies used to design devices with surfaces able to limit microbial adhesion and/or growth. A PubMed search of the published literature. One strategy is to design medical devices with a biocidal agent. Biocides can be incorporated into the materials or coated or covalently bonded, resulting either in release of the biocide or in contact killing without release of the biocide. The use of biocides in medical devices is debated because of the risk of bacterial resistance and potential toxicity. Another strategy is to modify the chemical or physical surface properties of the materials to prevent microbial adhesion, a complex phenomenon that also depends directly on microbial biological structure and the environment. Anti-adhesive chemical surface modifications mostly target the hydrophobicity features of the materials. Topographical modifications are focused on roughness and nanostructures, whose size and spatial organization are controlled. The most effective physical parameters to reduce bacterial adhesion remain to be determined and could depend on shape and other bacterial characteristics. A prevention strategy based on reducing microbial attachment rather than on releasing a biocide is promising. Evidence of the clinical efficacy of these surface-modified devices is lacking. Additional studies are needed to determine which physical features have the greatest potential for reducing adhesion and to assess the usefulness of antimicrobial coatings other than antibiotics.

Adolescent pregnancy, HIV, and other sexually transmitted infections (STIs) are major public health problems in the U.S. Implementing group-based interventions that address the sexual behavior of adolescents may reduce the incidence of pregnancy, HIV, and other STIs in this group. Methods for conducting systematic reviews from the Guide to Community Preventive Services were used to synthesize scientific evidence on the effectiveness of two strategies for group-based behavioral interventions for adolescents: (1) comprehensive risk reduction and (2) abstinence education on preventing pregnancy, HIV, and other STIs. Effectiveness of these interventions was determined by reductions in sexual risk behaviors, pregnancy, HIV, and other STIs and increases in protective sexual behaviors. The literature search identified 6579 citations for comprehensive risk reduction and abstinence education. Of these, 66 studies of comprehensive risk reduction and 23 studies of abstinence education assessed the effects of group-based interventions that address the sexual behavior of adolescents, and were included in the respective reviews. Meta-analyses were conducted for each strategy on the seven key outcomes identified by the coordination team-current sexual activity; frequency of sexual activity; number of sex partners; frequency of unprotected sexual activity; use of protection (condoms and/or hormonal contraception); pregnancy; and STIs. The results of these meta-analyses for comprehensive risk reduction showed favorable effects for all of the outcomes reviewed. For abstinence education, the meta-analysis showed a small number of studies, with inconsistent findings across studies that varied by study design and follow-up time, leading to considerable uncertainty around effect estimates. Based on these findings, group-based comprehensive risk reduction was found to be an effective strategy to reduce adolescent pregnancy, HIV, and STIs. No conclusions could be drawn on the effectiveness of group-based abstinence education. Published by Elsevier Inc.

This report summarizes current (as of 2011) guidelines or recommendations published by multiple agencies of the U.S. Department of Health and Human Services (DHHS) for prevention and control of human immunodeficiency virus (HIV) infection, viral hepatitis, sexually transmitted diseases (STDs), and tuberculosis (TB) for persons who use drugs illicitly. It also summarizes existing evidence of effectiveness for practices to support delivery of integrated prevention services. Implementing integrated services for prevention of HIV infection, viral hepatitis, STDs, and TB is intended to provide persons who use drugs illicitly with increased access to services, to improve timeliness of service delivery, and to increase effectiveness of efforts to prevent infectious diseases that share common risk factors, behaviors, and social determinants. This guidance is intended for use by decision makers (e.g., local and federal agencies and leaders and managers of prevention and treatment services), health-care providers, social service providers, and prevention and treatment support groups. Consolidated guidance can strengthen efforts of health-care providers and public health providers to prevent and treat infectious diseases and substance use and mental disorders, use resources efficiently, and improve health-care services and outcomes in persons who use drugs illicitly. An integrated approach to service delivery for persons who use drugs incorporates recommended science-based public health strategies, including 1) prevention and treatment of substance use and mental disorders; 2) outreach programs; 3) risk assessment for illicit use of drugs; 4) risk assessment for infectious diseases; 5) screening, diagnosis, and counseling for infectious diseases; 6) vaccination; 7) prevention of mother-to-child transmission of infectious diseases; 8) interventions for reduction of risk behaviors; 9) partner services and contact follow-up; 10) referrals and linkage to care; 11) medical treatment for infectious diseases; and 12) delivery of integrated prevention services. These strategies are science-based, public health strategies to prevent and treat infectious diseases, substance use disorders, and mental disorders. Treatment of infectious diseases and treatment of substance use and mental disorders contribute to prevention of transmission of infectious diseases. Integrating prevention services can increase access to and timeliness of prevention and treatment.

It is a hard work to develop an hightly effective cure and prevention of HIV/AIDS. The widespread used of some therapy approaches such as highly active anti retroviral therapy (HAART) has improved life quality and span of infected individuals. However, some limitations of these approaches prevent them achieving further advancement. Recent research on drug delivery approaches indicates that engineered nanosystems may bring positive effect on the improvement of current antiretroviral therapy. Furthermore, the basic researches of nanotechnology- based systems which prevent HIV transmission have been started. Therefore, nanotechnology may become a potential approach in the field of HIV/AIDS treatment and prevention. This chapter reviews the latest advancement in the field of nanotechnology-based systems which improve the fields of HIV/AIDS treatment and prevention.
Childhood Vaccination: Implications for Global and Domestic Public Health.
Younger, David S; Younger, Adam P J; Guttmacher, Sally
2016-11-01
The role of vaccination in the control and prevention of endemic and emerging diseases cannot be overemphasized. Induction of host protective immunity may be the most powerful tool and effective strategy in preventing the spread of potentially fatal disease and emerging illnesses, in particular in susceptible immunologically naive hosts. The strategy for vaccination programs is engrained in population studies recognizing benefit for the health and economic welfare of at-risk indigenous populations. Worldwide collaboration is a necessary aspect of vaccine-preventable diseases recognizing that even a small number of wild-type cases of an eradicated disease in one region presents opportunities for re-emergence of the disease in geographically remote areas.

Towards a Chlamydia trachomatis vaccine: how close are we?
Cochrane, Melanie; Armitage, Charles W; O'Meara, Connor P; Beagley, Kenneth W
2010-12-01
Chlamydia trachomatis is the leading cause of bacterial sexually transmitted infections and preventable blindness worldwide. The incidence of chlamydial sexually transmitted infections has increased rapidly and current antibiotic therapy has failed as an intervention strategy. The most accepted strategy for protection and/or control of chlamydial infections is a vaccine that induces both local neutralizing antibodies to prevent infections by the extracellular elementary bodies and a cell-mediated immune response to target the intracellular infection. This article will discuss the challenges in vaccine design for the prevention of chlamydial urogenital infection and/or disease, including selection of target antigens, discussion of effective delivery systems, immunization routes and adjuvants for induction of protective immunity at the targeted mucosal surface whilst minimizing severe inflammatory disease sequelae.

Background New York City (NYC) remains an epicenter of the HIV epidemic in the United States. Given the variety of evidence-based HIV prevention strategies available and the significant resources required to implement each of them, comparative studies are needed to identify how to maximize the number of HIV cases prevented most economically. Methods A new model of HIV disease transmission was developed integrating information from a previously validated micro-simulation HIV disease progression model. Specification and parameterization of the model and its inputs, including the intervention portfolio, intervention effects and costs were conducted through a collaborative process between the academic modeling team and the NYC Department of Health and Mental Hygiene. The model projects the impact of different prevention strategies, or portfolios of prevention strategies, on the HIV epidemic in NYC. Results Ten unique interventions were able to provide a prevention benefit at an annual program cost of less than $360,000, the threshold for consideration as a cost-saving intervention (because of offsets by future HIV treatment costs averted). An optimized portfolio of these specific interventions could result in up to a 34% reduction in new HIV infections over the next 20 years. The cost-per-infection averted of the portfolio was estimated to be $106,378; the total cost was in excess of $2 billion (over the 20 year period, or approximately $100 million per year, on average). The cost-savings of prevented infections was estimated at more than $5 billion (or approximately $250 million per year, on average). Conclusions Optimal implementation of a portfolio of evidence-based interventions can have a substantial, favorable impact on the ongoing HIV epidemic in NYC and provide future cost-saving despite significant initial costs.

Falls in older persons are prevalent and costly for the individual and the health system. Falls prevention guidelines have been developed from best evidence to minimise falls in older persons. To synthesise the literature on falls prevention strategies used by community dwelling older persons and/or their informal carers and to compare the commonly adopted strategies with those recommended by falls prevention guidelines. Health sciences databases for full text articles published in English plus reference list searching of included articles. An integrative review approach. Studies were included if they identified fall prevention management strategies used by community dwelling older adults and/or their informal carers. Quality appraisal was undertaken using appropriate Joanna Briggs Institute critical appraisal tools. Information relevant to the aim of the review were extracted and coded into categories then inductively sorted into sub-themes and themes. Of the seventeen studies included in the review, eleven identified older adults' falls prevention strategies, two investigated fall prevention strategies used by carers, and four explored perspectives of older persons together with their carers, representing the perspectives of an estimated 501 older persons and 102 carers. Strategies used by older adults arose because of self-awareness about their changing physical ability, and advice and support mainly from family or friends. Carer fall prevention strategy was predominantly around protection of the older adult from falling by discouraging independence. The fall self-management strategies adopted by older adults and their carers to prevent falls, in the main, do not align with international best practice fall prevention guidelines. Copyright © 2018.

Youth suicide prevention: does access to care matter?
Campo, John V
2009-10-01
Recent increases in adolescent suicide rates after a decade of decline highlight the relevance of pediatric suicide prevention. Existing strategies to intervene with youth at risk for suicide are largely based on the premise that access to effective services is of critical importance. This review aims to examine the relationship between youth suicide and access to care. Promising reductions in suicidal thinking and behavior have been associated with the application of manualized psychotherapies, collaborative interventions in primary care, lithium for mood-disordered adults, and clozapine in schizophrenia. Suicide rates correlate inversely with indices of care access across the lifespan, including antidepressant prescription rates. Suicide is a preventable cause of death, and any public health relevant effort to prevent youth suicide must include improving access to effective care for at-risk youth as a strategy. Education and training of professionals and consumers, the integration of mental health services in primary care, and the use of novel technologies to track and maintain contact with at-risk youth are worthy of study. Additional research on the relationship between specific treatments, especially antidepressants, and youth suicide risk reduction is desperately needed.
HIV Issues and Mapuches in Chile.
Cianelli, Rosina; Ferrer, Lilian; Cabieses, Báltica; Araya, Alejandra; Matsumoto, Cristina; Miner, Sarah
2008-01-01
Chile is a country with an incipient HIV epidemic. Just as in other countries, disadvantaged groups in Chile are contributing to the increased incidence of the disease. The Mapuche indigenous population is one such group that has been affected by the spread of HIV. However, no prevention programs are tailored to the culturally specific needs of this community. In recognition of this discrepancy, an academic-community partnership was formed to develop an HIV educational module for a Mapuche community. The module was developed for use as part of an already established health-related program. The aims of the module were to identify perceptions about HIV among Mapuches and present information specific to HIV and its prevention. Focus was placed on cultural sensitivity. A total of 16 Mapuches participated voluntarily and showed some knowledge regarding HIV, but they lacked an overall understanding as to how it is transmitted and why prevention strategies are effective. Continued collaboration between academia and affected communities as well as incorporating HIV information into established programs are effective strategies for delivering prevention information to disadvantaged populations and for further understanding their perceptions and health care needs.

The need for allergy prevention strategies has never been greater. Surging rates of food allergy and eczema are now adding to the already substantial burden of asthma and respiratory allergic diseases. The parallel rise in many other immune diseases suggests that the developing immune system is highly vulnerable to modern environmental changes. These strong environmental pressures may be one reason why simple allergen avoidance strategies have not been successful. Another more recent strategy to curtail the allergy epidemic has been to identify factors associated with modern lifestyle that may be causally linked with allergic disease, in an attempt to restore more favourable conditions for immune tolerance during early development. More hygienic conditions and disruption of microbial exposure have prompted strategies to restore this balance using probiotic and prebiotic supplements. Modern dietary changes linked with allergic diseases have prompted supplementation studies to assess the preventive merits of specific immunomodulatory dietary nutrients such as polyunsaturated fatty acids. Other nutrients such as antioxidants, folate, and vitamin D are also currently under investigation. Modern environmental pollutants have also been associated with adverse effects on immune development and the risk of disease. While many of these avenues have provided some promise, they have not yet translated into specific recommendations. Current evidence-based guidelines for allergy prevention remain limited to avoidance of cigarette smoke, promotion of breastfeeding and the use of hydrolysed formula when breastfeeding is not possible. Allergen avoidance strategies have been largely removed from most guidelines. It is hoped that a number of ongoing studies will help provide clearer recommendations around the use of probiotics, prebiotics, specific dietary nutrients and the role of early introduction of allergenic foods for the promotion of tolerance. Despite the current uncertainties, prevention remains the best long-term strategy to reduce the growing burden of allergic disease. Copyright © 2011 S. Karger AG, Basel.

Policy, systems, and environmental approaches are recommended for preventing childhood obesity. The objective of our study was to evaluate the Healthy Lifestyles Initiative, which aimed to strengthen community capacity for policy, systems, and environmental approaches to healthy eating and active living among children and families. The Healthy Lifestyles Initiative was developed through a collaborative process and facilitated by community organizers at a local children's hospital. The initiative supported 218 partners from 170 community organizations through training, action planning, coalition support, one-on-one support, and the dissemination of materials and sharing of resources. Eighty initiative partners completed a brief online survey on implementation strategies engaged in, materials used, and policy, systems, and environmental activities implemented. In accordance with frameworks for implementation science, we assessed associations among the constructs by using linear regression to identify whether and which of the implementation strategies were associated with materials used and implementation of policy, systems, and environmental activities targeted by the initiative. Each implementation strategy was engaged in by 30% to 35% of the 80 survey respondents. The most frequently used materials were educational handouts (76.3%) and posters (66.3%). The most frequently implemented activities were developing or continuing partnerships (57.5%) and reviewing organizational wellness policies (46.3%). Completing an action plan and the number of implementation strategies engaged in were positively associated with implementation of targeted activities (action plan, effect size = 0.82; number of strategies, effect size = 0.51) and materials use (action plan, effect size = 0.59; number of strategies, effect size = 0.52). Materials use was positively associated with implementation of targeted activities (effect size = 0.35). Community-capacity-building efforts can be effective in supporting community organizations to engage in policy, systems, and environmental activities for healthy eating and active living. Multiple implementation strategies are likely needed, particularly strategies that involve a high level of engagement, such as training community organizations and working with them on structured action plans.

Women in Nigeria face some of the highest maternal mortality risks in the world. We explore the benefits and cost-effectiveness of individual and integrated packages of interventions to prevent pregnancy-related deaths. We adapt a previously validated maternal mortality model to Nigeria. Model outcomes included clinical events, population measures, costs, and cost-effectiveness ratios. Separate models were adapted to Southwest and Northeast zones using survey-based data. Strategies consisted of improving coverage of effective interventions, and could include improved logistics. Increasing family planning was the most effective individual intervention to reduce pregnancy-related mortality, was cost saving in the Southwest zone and cost-effective elsewhere, and prevented nearly 1 in 5 abortion-related deaths. However, with a singular focus on family planning and safe abortion, mortality reduction would plateau below MDG 5. Strategies that could prevent 4 out of 5 maternal deaths included an integrated and stepwise approach that includes increased skilled deliveries, facility births, access to antenatal/postpartum care, improved recognition of referral need, transport, and availability quality of EmOC in addition to family planning and safe abortion. The economic benefits of these strategies ranged from being cost-saving to having incremental cost-effectiveness ratios less than $500 per YLS, well below Nigeria's per capita GDP. Early intensive efforts to improve family planning and control of fertility choices, accompanied by a stepwise effort to scale-up capacity for integrated maternal health services over several years, will save lives and provide equal or greater value than many public health interventions we consider among the most cost-effective (e.g., childhood immunization).
Predicting Use of Outdoor Fall Prevention Strategies: Considerations for Prevention Practices.
Chippendale, Tracy
2018-01-01
Outdoor falls are just as common as indoor falls, but have received less attention in research and practice. Behavioral strategies play an important role in outdoor fall prevention. The purpose of this study was to examine predictors of strategy use. Backward stepwise regression was used to study factors associated with use of outdoor fall prevention strategies among a random sample ( N = 120) of community-dwelling seniors. Significant negative predictors of strategy use included higher education levels ( p < .01) and living in an urban versus a suburban environment ( p < .01). Concern about falls and number of identified risks were positive predictors ( ps < .05). Differences were found between outdoor fallers and nonfallers in the use of three different types of strategies ( ps < .05). There are some differences in the profiles of people who use and do not use outdoor fall prevention strategies. Further study of additional factors is warranted.
Regional meeting on behavioral interventions for STD and AIDS prevention.
1991-01-01
The abstract of the regional meeting on behavioral interventions for sexually transmitted disease (STD) and AIDS prevention held in Jamaica in 1990, and sponsored by the Pan American Health Organization (PAHO)/WHO, is provided. The conference objectives were to assess existing STD intervention programs in the Americas, to improve coordination of health approaches, to evaluate knowledge and the implication for prevention interventions, to develop evaluation procedures on program effectiveness, and to provide guidelines and regional strategies for prevention and control of STD/HIV. In the inaugural session the idea that further spread of AIDS is minimized through both HIV and STD prevention programs was introduced. Effective strategies for AIDS prevention can be adapted for STD prevention. The new sexual candor has positively affected public understanding and comprehensive research, and applies to the discussion of all STDs. Coordination of STD and AIDS activity makes more efficient use of resources, and can be adapted to specific country needs. Coordination involved information sharing on effective prevention strategies, joint planning and provision of services such as serological testing and counseling, and integration of administration, personnel, and infrastructure for HIV/AIDS and STD prevention. Primary prevention and longterm change are desired. Coordination also involves joint efforts with other health care activities such as maternal and child health. Plenary session 1 was devoted to expert opinion on specific STDs, their physical and mental impact, and their economic and environmental impact. The day 2 plenary session reported on the increases in HIV and STD prevalence, and the various opportunities and needs for intervention. Target audiences were identified as those at high risk and teens and children as anticipatory risks. Religious opinions, societal norms, and public opinion were obstacles to program support. Other sessions dealt with condom promotion, the role and training of health workers, and counseling and partner notification. The final day's discussion focused on methods and materials approaches: general public, STD service, outreach, youth, and women. The findings of the last plenary session focused on funding and staffing shortages and lack of coordinated national programs. The Kingston Declaration, which proposes a plan for action for governments, community groups, nongovernment organizations, and others, was agreed upon. Basic components of any program should be accessibility, targeted risk groups, cultural sensitivity, and local design.

Recent outbreaks of chytridiomycosis, the disease of amphibians caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), have contributed to population declines of numerous amphibian species worldwide. The devastating impacts of this disease have led researchers to attempt drastic conservation measures to prevent further extinctions and loss of biodiversity. The conservation measures can be labour-intensive or expensive, and in many cases have been unsuccessful. We developed a mathematical model of Bd outbreaks that includes the effects of demographic stochasticity and within-host fungal load dynamics. We investigated the impacts of one-time treatment conservation strategies during the disease outbreak that occurs following the initial arrival of Bd into a previously uninfected frog population. We found that for all versions of the model, for a large fraction of parameter space, none of the one-time treatment strategies are effective at preventing disease-induced extinction of the amphibian population. Of the strategies considered, treating frogs with antifungal agents to reduce their fungal load had the greatest likelihood of a beneficial outcome and the lowest risk of decreasing the persistence of the frog population, suggesting that this disease mitigation strategy should be prioritized over disinfecting the environment or reducing host density.

We performed a systematic review to evaluate the evidence-based medicine regarding the main botanical extracts and their nutraceutical compounds correlated to skeletal muscle health in order to identify novel strategies that effectively attenuate skeletal muscle loss and enhance muscle function and to improve the quality of life of older subjects. This review contains all eligible studies from 2010 to 2015 and included 57 publications. We focused our attention on effects of botanical extracts on growth and health of muscle and divided these effects into five categories: anti-inflammation, muscle damage prevention, antifatigue, muscle atrophy prevention, and muscle regeneration and differentiation.

Outdoor professionals such as mountain guides are at a substantial risk of developing non-melanoma skin cancer (NMSC) due to solar ultraviolet radiation (UVR) exposure. Despite major recent primary prevention efforts, studies on secondary skin cancer prevention efforts are limited and corresponding data on outdoor workers scarce. To assess the sun protective behaviour and individual motivations for or against skin cancer screening examinations in the German mountain guide population to aid in the development of effective awareness and prevention strategies. A cross-sectional study among all registered mountain guides in Germany was conducted using a 35-item online questionnaire on primary and secondary prevention of NMSC as well as perceived barriers for prevention. A total of 145 mountain guides participated in the study in January 2017. Of these, 86.2% reported using sunscreen often or always, 62.1% with a sun protection factor (SPF) of 30-50% and 60.7% had undergone dermatological examination by a medical professional. The most common reasons for using secondary prevention efforts were hope of an early diagnosis (77.3%), fear of skin cancer (73.9%) and the intention to be aware of one's own health (70.5%). The main reasons for not doing so were absence of conspicuous skin conditions (63.2%) and feeling healthy (59.6%). Awareness of prevention strategies recommended by the scientific community is low among affected occupationally high-risk mountain guide populations. Understanding the specific needs of this high-risk group is essential for the development of sustainable awareness and prevention strategies. © 2018 European Academy of Dermatology and Venereology.

An ecological and theoretical deconstruction of a school-based obesity prevention program in Mexico.
Safdie, Margarita; Cargo, Margaret; Richard, Lucie; Lévesque, Lucie

Ecological intervention programs are recommended to prevent overweight and obesity in children. The National Institute of Public Health (INSP) in Mexico implemented a successful ecological intervention program to promote healthy lifestyle behaviors in school age children. This study assessed the integration of ecological principles and Social Cognitive Theory (SCT) constructs in this effective school-based obesity prevention program implemented in 15 elementary schools in Mexico City. Two coders applied the Intervention Analysis Procedure (IAP) to "map" the program's integration of ecological principles. A checklist gauged the use of SCT theory in program activities. Thirty-two distinct intervention strategies were implemented in one setting (i.e., school) to engage four different target-groups (students, parents, school representatives, government) across two domains (Nutrition and Physical Activity). Overall, 47.5% of the strategies targeted the school infrastructure and/or personnel; 37.5% of strategies targeted a key political actor, the Public Education Secretariat while fewer strategies targeted parents (12.5%) and children (3%). More strategies were implemented in the Nutrition domain (69%) than Physical Activity (31%). The most frequently used SCT construct within both intervention domains was Reciprocal Determinism (e.g., where changes to the environment influence changes in behavior and these behavioral changes influence further changes to the environment); no significant differences were observed in the use of SCT constructs across domains. Findings provide insight into a promising combination of strategies and theoretical constructs that can be used to implement a school-based obesity prevention program. Strategies emphasized school-level infrastructure/personnel change and strong political engagement and were most commonly underpinned by Reciprocal Determinism for both Nutrition and Physical Activity.

OBJECTIVES. Project DARE (Drug Abuse Resistance Education) is the most widely used school-based drug use prevention program in the United States, but the findings of rigorous evaluations of its effectiveness have not been considered collectively. METHODS. We used meta-analytic techniques to review eight methodologically rigorous DARE evaluations. Weighted effect size means for several short-term outcomes also were compared with means reported for other drug use prevention programs. RESULTS. The DARE effect size for drug use behavior ranged from .00 to .11 across the eight studies; the weighted mean for drug use across studies was .06. For all outcomes considered, the DARE effect size means were substantially smaller than those of programs emphasizing social and general competencies and using interactive teaching strategies. CONCLUSIONS. DARE's short-term effectiveness for reducing or preventing drug use behavior is small and is less than for interactive prevention programs. PMID:8092361
Clustering, climate and dengue transmission.
Junxiong, Pang; Yee-Sin, Leo
2015-06-01
Dengue is currently the most rapidly spreading vector-borne disease, with an increasing burden over recent decades. Currently, neither a licensed vaccine nor an effective anti-viral therapy is available, and treatment largely remains supportive. Current vector control strategies to prevent and reduce dengue transmission are neither efficient nor sustainable as long-term interventions. Increased globalization and climate change have been reported to influence dengue transmission. In this article, we reviewed the non-climatic and climatic risk factors which facilitate dengue transmission. Sustainable and effective interventions to reduce the increasing threat from dengue would require the integration of these risk factors into current and future prevention strategies, including dengue vaccination, as well as the continuous support and commitment from the political and environmental stakeholders.

Cardiovascular disease (CVD) places great financial strain on the health care system and dramatically affects individual quality of life. As primary health care providers, nurse practitioners (NPs) are ideally positioned to advise clients on risk factor and lifestyle modifications that ameliorate the impact of CVD. While the lifestyle targets for CVD prevention are established, the most effective means of achieving these goals remain uncertain. Behaviour modification strategies, including motivational interviewing (MI) and the transtheoretical model (TTM), have been suggested, but neither approach is established as being more efficacious than the other. In this paper, evidence on the effectiveness of the two approaches for modifying smoking, diet, and exercise behaviour are presented, and a recommendation for NP practice is made.

This study examines the effect of condom negotiation strategies on condom use and partner type and substance use before sex as moderators of strategy effectiveness. Women reported their daily sexual behavior during the last month. Withholding sex was more strongly associated with condom use when utilized with a non-casual sex partner. Directly requesting condom use was more strongly and using deceptive reasons to influence condom use was less strongly related to condom use during substance use. Results underscore the importance of understanding the contexts in which condom negotiation strategies are successful in order to improve HIV/sexually transmitted infection prevention efforts among women.
A strategy of clinical tolerance for the prevention of HIV and AIDS in China.
Wang, Y
2000-02-01
HIV infection and AIDS create many dilemmas in Chinese AIDS/HIV prevention policy. A strategy of clinical tolerance is proposed to address these dilemmas. The immediate purpose of the strategy of clinical tolerance is to win the cooperation of members of stigmatized groups at high risk for contracting HIV infection and AIDS, which occurs as a result of acts done in private and thus beyond the reach of regulation. The strategy of clinical tolerance differs from both tolerance as liberal tolerance and tolerance as a moral ideal of tolerance. A strategy of clinical tolerance does not ask the government, health worker, health official or the public to change either laws or the disapproval of prostitution, homosexuality and drug use. A strategy of clinical tolerance asks, instead, that we weigh what we may regard as the wrong involved in prostitution, homosexuality, and drug use against the greater evil of an HIV/AIDS epidemic. A strategy of clinical tolerance offers the most effective and practical way to confront a growing and significant public health problem in China.
Preventive strategies for mental health.

Available treatment methods have shown little effect on the burden associated with mental health disorders. We review promising universal, selective, and indicated preventive mental health strategies that might reduce the incidence of mental health disorders, or shift expected trajectories to less debilitating outcomes. Some of these interventions also seem to be cost-effective. In the transition to mental illness, the cumulative lifetime effect of multiple small effect size risk factors progressively increases vulnerability to mental health disorders. This process might inform different levels and stages of tailored interventions to lessen risk, or increase protective factors and resilience, especially during sensitive developmental periods. Gaps between knowledge, policy, and practice need to be bridged. Future steps should emphasise mental health promotion, and improvement of early detection and interventions in clinical settings, schools, and the community, with essential support from society and policy makers.

Assessing the quality of mental health promotion and prevention in Croatia: the case of Istria.
Mihic, Josipa; Novak, Miranda; Hosman, Clemens; Domitrovich, Celene
2017-06-01
While the availability of mental health promotion and prevention programs worldwide is growing, there is divergence in their level of effectiveness that has led to increasing interest in the development of 'effect management' strategies. Mental health promotion and prevention science and practice has a relatively young history in Croatia, but major investments towards its development have been made over the last decade. This paper reports on a research project that took place within the Istrian Region. The long-term goal of the initiative is to establish quality assurance indicators for mental health promotion and prevention interventions. The current study involved adapting the Dutch Preffi 2.0 instrument for use in Croatia. The content of the Preffi reflects the literature regarding research-based effect predictors. An instrument allows users to assess whether programs have been designed and implemented in ways that maximize their ability to be effective. The Preffi scores can be used for improving a program and the quality with which it is implemented. The first aim of the study is to determine if independent researchers can use the Preffi reliably as a quality assessment instrument. The second aim is to use the Preffi to describe the quality of one cohort of mental health promotion and prevention programs. The study represents the first steps toward developing a strategy for quality assurance that strengthens community capacity for effective service delivery and that could inform other countries whose mental health promotion and prevention efforts are in early stages of development. © The Author 2015.

Introduction Despite progress in scaling up antiretroviral treatment, HIV prevention strategies have not been successful in significantly curbing HIV incidence in Latin America. HIV prevention interventions need to be expanded to target the most affected key populations with a combination approach, including new high impact technologies. Oral pre-exposure prophylaxis (PrEP) is recommended as additional prevention choice for individuals at higher risk of infection and could become a cost-effective prevention tool. We discuss the barriers and solutions for a fair consideration of PrEP as part of combination HIV prevention strategies in Latin America. Discussion Although demonstration projects are ongoing or being planned in a number of countries, to date no Latin American country has implemented a public PrEP programme. The knowledge of policymakers about PrEP implementation needs to be strengthened, and programmatic guidance and cost estimate tools need to be developed to support adequate planning. Despite high levels of awareness among health providers, especially if engaged in HIV or key population care, willingness to prescribe PrEP is still low due to the lack of national policies and guidelines. Key populations, especially men who have sex with men, transgender women and sex workers, have been engaged in demonstration projects, and qualitative research shows high awareness and willingness to use PrEP, especially if accessible in the public sector for free or at affordable price. Concerns of safety, adherence, effectiveness and risk compensation need to be addressed through targeted social communication strategies to improve PrEP knowledge and stimulate demand. Alliance among policymakers, civil society and representatives from key populations, healthcare providers and researchers will be critical for the design and successful implementation of PrEP demonstration projects of locally adapted delivery models. The use of mechanisms of joint negotiation and procurement of antiretrovirals could reduce costs and significantly increase the cost-effectiveness of PrEP. Conclusions PrEP is an additional prevention tool and should be implemented in combination and synergy with other prevention interventions. PrEP programmes should target high-risk individuals from key populations for higher cost-effectiveness. Demonstration projects may generate strategic information for and lead to the implementation of full-scale PrEP programmes. PMID:27760687

Cardiovascular disease (CVD) is the leading cause of death worldwide. Herbal medicine and exercise interventions have individually been shown to be effective in the prevention and management of CVD. However, the complementary roles of herbal medicine and exercise interventions for CVD prevention and management have not been adequately reported. 1. Identify studies analysing complementary roles of herbal medicine and exercise intervention in CVD prevention and management, 2. Identify herbs and exercise strategies that have been reported to exhibit complementary roles in CVD prevention and management, and 3. Summarize evidence of complementary roles of herbal medicine and exercise interventions for CVD prevention and management. PubMed, CINAHL and Web of Science were searched with a customised search strategy in May 2015. Two reviewers screened the search results for inclusion using pre-specified criteria. Data were extracted from full text of selected abstracts in a predetermined template by two reviewers and verified by the third reviewer when needed. A total of 35 titles were identified for full texts review after screening 827 abstracts. Data were extracted from 23 titles, representing 12 human studies and six animal studies. This review identified effects of 14 different herbs and 10 exercise strategies on over 18 CVD risk factors and markers. Complementary roles of herbal medicine and exercise were reported from five studies. Evidence of complementary role of herbal medicine and exercise is emerging from animal studies. More robust clinical studies on proven risk factors are needed before they can be recommended for clinical practice.

The evidence that supports the preventive effect of combination antiretroviral treatment (cART) in HIV sexual transmission suggested the so-called 'treatment as prevention' (TAP) strategy as a promising tool for slowing down HIV transmission. As the messages and attitudes towards condom use in the context of TAP appear to be somehow confusing, the aim here is to assess whether relying on cART alone to prevent HIV transmission can currently be recommended from the Public Health perspective. A review is made of the literature on the effects of TAP strategy on HIV transmission and the epidemiology of other sexual transmitted infections (STIs) in the cART era, and recommendations from Public Health institutions on the TAP as of February 2014. The evolution of HIV and other STIs in Barcelona from 2007 to 2012 has also been analysed. Given that the widespread use of cART has coincided with an increasing incidence of HIV and other STIs, mainly amongst men who have sex with men, a combination and diversified prevention methods should always be considered and recommended in counselling. An informed decision on whether to stop using condoms should only be made by partners within stable couples, and after receiving all the up-to-date information regarding TAP. From the public health perspective, primary prevention should be a priority; therefore relying on cART alone is not a sufficient strategy to prevent new HIV and other STIs.

Systematic reviews with meta-analyses and meta-regression suggest that timely probiotic use can prevent Clostridium difficile infection (CDI) in hospitalized adults receiving antibiotics, but the cost effectiveness is unknown. We sought to evaluate the cost effectiveness of probiotic use for prevention of CDI versus no probiotic use in the United States. We programmed a decision analytic model using published literature and national databases with a 1-year time horizon. The base case was modeled as a hypothetical cohort of hospitalized adults (mean age 68) receiving antibiotics with and without concurrent probiotic administration. Projected outcomes included quality-adjusted life-years (QALYs), costs (2013 US dollars), incremental cost-effectiveness ratios (ICERs; $/QALY), and cost per infection avoided. One-way, two-way, and probabilistic sensitivity analyses were conducted, and scenarios of different age cohorts were considered. The ICERs less than $100000 per QALY were considered cost effective. Probiotic use dominated (more effective and less costly) no probiotic use. Results were sensitive to probiotic efficacy (relative risk <0.73), the baseline risk of CDI (>1.6%), the risk of probiotic-associated bactermia/fungemia (<0.26%), probiotic cost (<$130), and age (>65). In probabilistic sensitivity analysis, at a willingness-to-pay threshold of $100000/QALY, probiotics were the optimal strategy in 69.4% of simulations. Our findings suggest that probiotic use may be a cost-effective strategy to prevent CDI in hospitalized adults receiving antibiotics age 65 or older or when the baseline risk of CDI exceeds 1.6%.
